TI Combat amputees' health-related quality of life and psychological outcomes: A brief report from the wounded warrior recovery project SO JOURNAL OF TRAUMA AND ACUTE CARE SURGERY LA English DT Article DE Quality of life; combat amputees; Wounded Warrior Recovery Project ID VIETNAM VETERANS; LIMB LOSS; AFGHANISTAN; IRAQ; SERVICEMEMBERS; INJURY AB BACKGROUND This study extends what is known about long-term health-related quality of life (HrQoL) and other psychosocial outcomes (i.e., depression, posttraumatic stress disorder [PTSD]) among US military combat amputees serving in Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn. METHODS A total of 63 combat amputees were identified from the Wounded Warrior Recovery Project, a study assessing long-term self-reported HrQoL and psychological outcomes among those wounded during military service. Another 477 service members from the Wounded Warrior Recovery Project were identified as a comparison group (i.e., nonamputees with moderate to severe extremity injuries). RESULTS After adjusting for age, time since injury, overall injury severity, and traumatic brain injury, amputees had poorer functional HrQoL than those in the nonamputee comparison group overall and in the specific area related to performance of usual activities, and, to some degree, chronic and acute symptoms, and mobility/self-care. On the other hand, depression and PTSD symptoms were not different for the two groups. CONCLUSION Results suggest that when assessed over 5 years postinjury, on average, amputees have unique physical and functional limitations, yet do not report greater depression or PTSD symptoms than others seriously injured in combat. It may be that state-of-the-art integrated amputee care that includes support networks and emphasis on adjustment and psychological health may increase successful coping and adjustment, at least to a level that is on par with other types of serious combat injury.

TI Effect of Load Magnitude and Distribution on Lumbar Spine Posture in Active-duty Marines SO SPINE LA English DT Article DE load carriage; load distribution; load magnitude; lumbar spine; military; posture; sacral slope ID CARRIAGE; KINEMATICS; BACKPACK; CURVATURE; CHILDREN AB Study Design. Repeated measures. Objective. The purpose of this study was to quantify the effect of operationally relevant loads and distributions on lumbar spine (LS) in a group of active-duty Marines. Summary of Background Data. Low-back pain has been associated with heavy load carriage among military personnel. Although there are data describing the LS posture in response to load, the effect of varying load characteristics on LS posture remains unknown. Methods. Magnetic resonance images of Marines (n = 12) were acquired when standing unloaded and when carrying 22, 33, and 45 kg of load distributed both 50% to 50% and 20% to 80% anteriorly and posteriorly. Images were used to measure LS and pelvic postures. Two-way repeated-measures ANOVA and posthoc tests were used to compare LS posture across load magnitudes and distributions (alpha = 0.05). This project was founded by the US Army Medical Research Acquisition Activity, Award No. W81XWH-13-2-0043, under Work Unit No. 1310. Results. No changes in LS posture were induced when load was evenly distributed. When load was carried in the 20% to 80% distribution lumbosacral flexion increased as a result of sacral anterior rotation and overall reduced lumbar lordosis. This pattern was greater as load was increased between 22 and 33 kg, but did not increase further between 33 and 45 kg. We observed that the inferior LS became uniformly less lordotic, independently of load magnitude. However, the superior LS became progressively more lordotic with increasing load magnitude Conclusion. Postural adaptations were found only when load was carried with a posterior bias, suggesting that load-carriage limits based on postural changes are relevant when loads are nonuniformly distributed. Although the tendency would be to interpret that loads should be carried symmetrically to protect the spine, the relationship between postural changes and injury are not clear. Finally, the operational efficiency of carrying load in this distribution needs to be tested.

TI Mechanical abuse simulation and thermal runaway risks of large-format Li-ion batteries SO JOURNAL OF POWER SOURCES LA English DT Article DE Large format Li-ion battery; Mechanical abuse; Pinch-torsion; Thermal runaway risk ID CELLS AB Internal short circuit of large-format Li-ion pouch cells induced by mechanical abuse was simulated using a modified mechanical pinch test. A torsion force was added manually at similar to 40% maximum compressive loading force during the pinch test. The cell was twisted about 5 degrees to the side by horizontally pulling a wire attached to the anode tab. The combined torsion-compression force created small failure at the separator yet allowed testing of fully charged large format Li-ion cells without triggering thermal runaway. Two types of commercial cells were tested using 4-6 cells at each state-of-charge (SOC). Commercially available 18 Ahr LiFePO4 (LFP) and 25 Ahr Li(NiMnCo)(1/3)O-2 (NMC) cells were tested, and a thermal runaway risk (TRR) score system was used to evaluate the safety of the cells under the same testing conditions. The aim was to provide the cell manufacturers and end users with a tool to compare different designs and safety features. (C) 2017 Elsevier B.V. All rights reserved.

Various sequences of increasing depth indentations were carried out using a 1.0 inch (25.4 mm) diameter steel ball with steel plate as a rigid support surface. The indentation depths were between 0.025" and 0.250" with main indentation increments tests of 0.025" steps. Increment steps of 0.100" and 0.005" were used to pinpoint the onset of internal-short that occurred between 0.245" and 0.250". The indented cells were disassembled and inspected for internal damage. Load vs. time curves were compared with the developed computer models. Separator thinning leading to the short circuit was simulated using both isotropic and anisotropic mechanical properties. Our study show that separators behave differently when tested as a single layer vs. a stack in a typical pouch cell. The collective responses of the multiple layers must be taken into account in failure analysis. A model that resolves the details of the individual internal cell components was able to simulate the internal deformation of the large format cells and the onset of failure assumed to coincide with the onset of internal short circuit.

The CMC targets were subject to ballistic impact at a normal incidence angle while being loaded under different levels of tensile loading in order to simulate conditions of rotating aeroengine airfoils. The impact damage of frontal and back surfaces was assessed with respect to impact velocity and load factor. Subsequent postimpact residual strength was also estimated to determine quantitatively the severity of impact damage. Impact force was predicted based on the principles of energy conservation.

To develop better strategies to monitor and control metallic biofilms, it is necessary to resolve the bacterial composition within the biofilm. This study aimed to determine if differences in electrochemical current could influence the composition of dominant bacteria in a metallic biofilm, and if so, determine the level of resolution using metagenomic amplicon sequencing. Current was generated by creating galvanic couples between cathodes made from stainless steel and anodes made from carbon steel, aluminum, or copper nickel and exposing them in the Delaware Bay. Stainless steel cathodes (SSCs) coupled to aluminum or carbon steel generated a higher mean current (0.39 mA) than that coupled to copper nickel (0.17 mA). Following 3 months of exposure, the bacterial composition of biofilms collected from the SSCs was determined and compared. Dominant bacterial taxa from the two higher current SSCs were different from that of the low-current SSC as determined by DGGE and verified by Illumina DNA-seq analysis. These results demonstrate that electrochemical current could influence the composition of dominant bacteria in metallic biofilms and that amplicon sequencing is sufficient to complement current methods used to study metallic biofilms in marine environments.

This paper examines factors contributing to second stage survey non-response during the baseline data collection for the Millennium Cohort Family Study, a large longitudinal study of US service members and their spouses from all branches of the military. Methods: Multivariate logistic regression analysis was used to develop a comprehensive response propensity model. Results: Results showed the majority of service member sociodemographic, military, and administrative variables were significantly associated with non-response, along with various health behaviours, mental health indices, and financial and social issues. However, effects were quite small for many factors, with a few demographic and survey administrative variables accounting for the most substantial variance. Conclusions: The Millennium Cohort Family Study was impacted by a number of non-response factors that commonly affect survey research. In particular, recruitment of young, male, and minority populations, as well as junior ranking personnel, was challenging. Despite this, our results suggest the success of representative population sampling can be effectively augmented through targeted oversampling and recruitment, as well as a comprehensive survey weighting strategy.

We conducted retrospective analysis of Department of Defense and Department of Veterans Affairs health data for lower extremity combat-injured patients with (1) unilateral amputation within 90 days postinjury (early amputation, n = 440), (2) unilateral amputation more than 90 days postinjury (late amputation, n = 78), or (3) leg-threatening injuries without amputation (limb salvage, n = 107). Patient medical records were analyzed for four years postinjury. After adjusting for group differences, early amputation was generally associated with a lower or similar prevalence for adverse physical and psychological diagnoses (e. g., pain, osteoarthritis, posttraumatic stress disorder) versus late amputation and/or limb salvage. By contrast, early amputation was associated with an increased likelihood of osteoporosis during the first year postinjury. The prevalence of posttraumatic stress disorder increased for all patient groups over four years postinjury, particularly in the second year. The different clinical outcomes among combat extremity injured patients treated with early amputation, late amputation, or limb salvage highlight their different healthcare requirements. These findings can inform and optimize the specific treatment pathways that address the physical and psychological healthcare needs of such patients over time.

TI Could Circumcision of HIV-Positive Males Benefit Voluntary Medical Male Circumcision Programs in Africa? Mathematical Modeling Analysis SO PLOS ONE LA English DT Article ID SUB-SAHARAN AFRICA; RANDOMIZED CONTROLLED-TRIAL; TRANSMISSION; RISK; INFECTION; UGANDA; IMPACT; WOMEN; MEN; PREVENTION AB Background The epidemiological and programmatic implications of inclusivity of HIV-positive males in voluntary medical male circumcision (VMMC) programs are uncertain. We modeled these implications using Zambia as an illustrative example. Methods and Findings We used the Age-Structured Mathematical (ASM) model to evaluate, over an intermediate horizon (2010-2025), the effectiveness (number of VMMCs needed to avert one HIV infection) of VMMC scale-up scenarios with varying proportions of HIV-positive males. The model was calibrated by fitting to HIV prevalence time trend data from 1990 to 2014. We assumed that inclusivity of HIV positive males may benefit VMMC programs by increasing VMMC uptake among higher risk males, or by circumcision reducing HIV male-to-female transmission risk. All analyses were generated assuming no further antiretroviral therapy (ART) scale-up. The number of VMMCs needed to avert one HIV infection was projected to increase from 12.2 VMMCs per HIV infection averted, in a program that circumcises only HIV-negative males, to 14.0, in a program that includes HIV-positive males. The proportion of HIV-positive males was based on their representation in the population (e.g. 12.6% of those circumcised in 2010 would be HIV-positive based on HIV prevalence among males of 12.6% in 2010). However, if a program that only reaches out to HIV-negative males is associated with 20% lower uptake among higher-risk males, the effectiveness would be 13.2 VMMCs per infection averted. If improved inclusivity of HIV-positive males is associated with 20% higher uptake among higher-risk males, the effectiveness would be 12.4. As the assumed VMMC efficacy against male-to-female HIV transmission was increased from 0% to 20% and 46%, the effectiveness of circumcising regardless of HIV status improved from 14.0 to 11.5 and 9.1, respectively. The reduction in the HIV incidence rate among females increased accordingly, from 24.7% to 34.8% and 50.4%, respectively. Conclusion Improving inclusivity of males in VMMC programs regardless of HIV status increases VMMC effectiveness, if there is moderate increase in VMMC uptake among higher-risk males and/or if there is moderate efficacy for VMMC against male-to-female transmission. In these circumstances, VMMC programs can reduce the HIV incidence rate in males by nearly as much as expected by some ART programs, and additionally, females can benefit from the intervention nearly as much as males.

It is well established that growth of the secondary beta phase is temperature driven, however there is little understanding about the role of prior strain in the beta phase nucleation and growth process. Understanding the effect of cold rolling will also bring new insight into better thermomechanical treatments leading to a more appropriate temper to improve sensitization resistance. In this study cold rolled AA5456-H116 is observed during in situ transmission electron microscopy heating experiments. The results of this study show the impact of an increased dislocation density, due to cold rolling, on beta phase precipitation as well as the effect of misorientation on growth and kinetics. The effect of additional dislocations is also observed to show an increase in precipitate density and a lowering of nucleation temperature attributed to Mg pipe diffusion.

TI Diabetes and breast cancer mortality in Black women SO CANCER CAUSES & CONTROL LA English DT Article DE Black women; Diabetes; Breast cancer; Mortality ID MELLITUS; SURVIVAL; INSULIN; COHORT; IMPACT AB Breast cancer mortality is higher in Black women than in White women. The prevalence of type 2 diabetes mellitus is also higher, yet data on whether diabetes affects breast cancer mortality in this population are lacking. We investigated the relation of diabetes at the time of breast cancer diagnosis to breast cancer mortality in the Black Women's Health Study, a prospective cohort study. 1,621 Black women with invasive breast cancer diagnosed in 1995-2013 were followed by mailed questionnaires and searches of the National Death Index. Multivariable Cox regression analysis was used to compute hazard ratios (HRs) for diabetes in relation to breast cancer mortality and all-cause mortality, with adjustment for age, stage, treatment modality, estrogen receptor (ER) status, and body mass index. There were 368 deaths during follow-up, of which 273 were due to breast cancer. Breast cancer mortality was significantly increased in women who had been diagnosed with diabetes at least 5 years before breast cancer occurrence, HR 1.86 (95% CI 1.20-2.89), with elevations observed for both ER+ and ER- breast cancer. All-cause mortality was also higher in diabetics, with HRs of 1.54 (95% CI 1.12-2.07) overall and 2.26 (95% CI 1.62-3.15) for ae 5-year duration of diabetes relative to non-diabetics. Our results present the first solid evidence of a positive association of type 2 diabetes with breast cancer mortality in Black women. Given the higher prevalence and earlier onset of type 2 diabetes in Black women, it is likely that diabetes contributes to racial disparities in breast cancer mortality.

Since this variance may be explained by the difference in structural arrangement of bone. tissue, micro-computed tomography (mu CT) was used in conjunction with mechanical testing to study the relationship between the microstructure of human skull cortical coupons and their mechanical response. Ninety-seven bone samples were machined from the cortical tables of the calvaria of ten fresh post mortem human surrogates and tested in dynamic tension until failure. A linear response between stress and strain was observed until close to failure, which occurred at 0.6% strain on average. The effective modulus of elasticity for the coupons was 12.01 +/- 3.28 GPa. Porosity of the test specimens, determined from mu CT, could explain only 51% of the variation of their effective elastic modulus. Finite element (FE) models of the tested specimens built from mu CT images indicated that modeling the microstructural arrangement of the bone, in addition to the porosity, led to a marginal improvement of the coefficient of determination to 54%. Modulus for skull cortical bone for an element size of 50 mu m was estimated to be 19 GPa at an average. Unlike the load bearing bones of the body, almost half of the variance in the mechanical properties of cortical bone from the skull may be attributed to differences at the sub-osteon (< 50 mu m) level. ANOVA tests indicated that effective failure stress and strain varied significantly between the frontal and parietal bones, while the bone phase modulus was different for the superior and inferior aspects of the calvarium. The micro FE models did not indicate any anisotropy attributable to the pores observable under mu CT.

TI Frequency of influenza H3N2 intra-subtype reassortment: attributes and implications of reassortant spread SO BMC BIOLOGY LA English DT Article DE Influenza; Reassortment; H3N2; Spread ID CIRCULATING RECOMBINANT FORM; A VIRUS REVEALS; A(H3N2) VIRUSES; PHYLOGENETIC INFERENCE; MAXIMUM-LIKELIHOOD; MOSAIC STRUCTURE; GENOME ANALYSIS; HIV TYPE-1; EVOLUTION; SEQUENCES AB Background: Increasing evidence suggests that influenza reassortment not only contributes to the emergence of new human pandemics but also plays an important role in seasonal influenza epidemics, disease severity, evolution, and vaccine efficacy. We studied this process within 2091 H3N2 full genomes utilizing a combination of the latest reassortment detection tools and more conventional phylogenetic analyses. Results: We found that the amount of H3N2 intra-subtype reassortment depended on the number of sampled genomes, occurred with a steady frequency of 3.35%, and was not affected by the geographical origins, evolutionary patterns, or previous reassortment history of the virus. We identified both single reassortant genomes and reassortant clades, each clade representing one reassortment event followed by successful spread of the reassorted variant in the human population. It was this spread that was mainly responsible for the observed high presence of H3N2 intra-subtype reassortant genomes. The successfully spread variants were generally sampled within one year of their formation, highlighting the risk of their rapid spread but also presenting an opportunity for their rapid detection. Simultaneous spread of several different reassortant lineages was observed, and despite their limited average lifetime, second and third generation reassortment was detected, as well as reassortment between viruses belonging to different vaccine-associated clades, likely displaying differing antigenic properties. Some of the spreading reassortants remained confined to certain geographical regions, while others, sharing common properties in amino acid positions of the HA, NA, and PB2 segments, were found throughout the world. Conclusions: Detailed surveillance of seasonal influenza reassortment patterns and variant properties may provide unique information needed for prediction of spread and construction of future influenza vaccines.

TI Theoretical Study of Cu/Mg Core-shell Nanocluster Formation SO JOURNAL OF PHYSICAL CHEMISTRY A LA English DT Article ID GENERALIZED GRADIENT APPROXIMATION; HELIUM DROPLETS; EXCHANGE; NANOPARTICLES; COMPOSITES; NANOSCALE; ALUMINUM; GROUP-11; BEHAVIOR; SYSTEM AB In a recently reported helium droplet-mediated deposition experiment to produce copper-coated magnesium core-shell nanoclusters, structural inversion was observed, which resulted in copper in the nanocluster interior, surrounded by oxidized magnesium on the copper surface. This study utilizes density functional theory methods to model the migration of copper atoms into the interior of a magnesium nanocluster to probe the energetics of this process and to compare it to the complementary process of magnesium atom migration into the interior of a copper nanocluster. Potential energy surfaces describing the forced migration of copper (magnesium) atoms into the interior of a 30-atom magnesium (copper) cluster were generated using the B3PW91 hybrid generalized gradient approximation functional with the augmented correlation consistent core valence polarized triple-zeta basis set for magnesium and a pseudopotential plus valence-only basis set for copper. The estimated barrier for atomic copper to penetrate the surface of Mg-30 is 0.6 kcal mol(-1). In contrast, the migration of atomic magnesium into the interior of Cum crosses an estimated barrier of 6 kcal mol(-1). These results are qualitatively consistent with the observed structural inversion of copper-coated magnesium nanoclusters and also suggest that inversion of a magnesium coated copper duster is less likely to occur.

A desirable goal would be the possibility to tune between all three regimes of nearly perfect reflection, absorption, and transmission within the same device, thus swapping between the cases R -> 1, A -> 1, and T -> 1 dynamically. We here show that a dielectric interfaced with a graphene layer on each side allows for precisely this: by tuning only the Fermi level of graphene, all three regimes can be reached in the THz regime and below. Moreover, we show that the inclusion of cylindrical defects in the system offers a different type of control of the scattering of electromagnetic waves by means of the graphene layers.

TI Scheduled evening sleep and enhanced lighting improve adaptation to night shift work in older adults SO OCCUPATIONAL AND ENVIRONMENTAL MEDICINE LA English DT Article DE aging ID CIRCADIAN PHASE; AGE; PERFORMANCE; SAFETY; RISK; TIME; LIFE; CONSEQUENCES; METAANALYSIS; PREVALENCE AB Objectives We tested whether a sleep and circadian-based treatment shown to improve circadian adaptation to night shifts and attenuate negative effects on alertness, performance and sleep in young adults would also be effective in older adults. Methods We assessed subjective alertness, sustained attention (psychomotor vigilance task, PVT), sleep duration (actigraphy) and circadian timing (salivary dim-light melatonin onset, DLMO) in 18 older adults (57.23.8years; meanSD) in a simulated shift work protocol. 4 day shifts were followed by 3 night shifts in the laboratory. Participants slept at home and were randomised to either the treatment group (scheduled evening sleep and enhanced lighting during the latter half of night shifts) or control group (ad-lib sleep and typical lighting during night shifts). Results Compared with day shifts, alertness and sustained attention declined on the first night shift in both groups, and was worse in the latter half of the night shifts. Alertness and attention improved on nights 2 and 3 for the treatment group but remained lower for the control group. Sleep duration in the treatment group remained similar to baseline (6-7hours) following night shifts, but was shorter (3-5hours) following night shifts in the control group. Treatment group circadian timing advanced by 169.3 +/- 16.1min (mean +/- SEM) but did not shift (-9.7 +/- 9.9min) in the control group. Conclusions The combined treatment of scheduled evening sleep and enhanced lighting increased sleep duration and partially aligned circadian phase with sleep and work timing, resulting in improved night shift alertness and performance.

TI Visualization of Whole-Night Sleep EEG From 2-Channel Mobile Recording Device Reveals Distinct Deep Sleep Stages with Differential Electrodermal Activity SO FRONTIERS IN HUMAN NEUROSCIENCE LA English DT Article DE EEG; sleep; spectral decomposition; electrodermal activity; deep sleep; slow wave sleep; sleep scoring algorithm ID HIDDEN MARKOV MODEL; HEALTHY-INDIVIDUALS; ELECTROENCEPHALOGRAM; HUMANS; STATES; LIFE AB Brain activity during sleep is a powerful marker of overall health, but sleep lab testing is prohibitively expensive and only indicated for major sleep disorders. This report demonstrates that mobile 2-channel in-home electroencephalogram (EEG) recording devices provided sufficient information to detect and visualize sleep EEG. Displaying whole-night sleep EEG in a spectral display allowed for quick assessment of general sleep stability, cycle lengths, stage lengths, dominant frequencies and other indices of sleep quality. By visualizing spectral data down to 0.1 Hz, a differentiation emerged between slow-wave sleep with dominant frequency between 0.11 Hz or 13 Hz, but rarely both. Thus, we present here the new designations, Hi and Lo Deep sleep, according to the frequency range with dominant power. Simultaneously recorded electrodermal activity (EDA) was primarily associated with Lo Deep and very rarely with Hi Deep or any other stage. Therefore, Hi and Lo Deep sleep appear to be physiologically distinct states that may serve unique functions during sleep. We developed an algorithm to classify five stages (Awake, Light, Hi Deep, Lo Deep and rapid eye movement (REM)) using a Hidden Markov Model (HMM), model fitting with the expectation-maximization (EM) algorithm, and estimation of the most likely sleep state sequence by the Viterbi algorithm. The resulting automatically generated sleep hypnogram can help clinicians interpret the spectral display and help researchers computationally quantify sleep stages across participants. In conclusion, this study demonstrates the feasibility of in-home sleep EEG collection, a rapid and informative sleep report format, and novel deep sleep designations accounting for spectral and physiological differences.

A prospective cohort study. Objective. Activities performed during military operations vary in complexity and physical demand. The risk for mental illness following military combat deployment has been well documented. However, information regarding the possible contribution of back pain to decreased mental and functional health is scarce. To our knowledge, this is the first study to prospectively assess deployment and self-reported recent back pain in a population-based U.S. military cohort. Summary of Background Data. The study consisted of Millennium Cohort participants who were followed for the development of back pain for an average of 3.9 years. Methods. Descriptive statistics and longitudinal analyses were used to assess the temporal relationship of deployment with self-reported recent back pain at follow-up (N = 53,933). Results. Recent back pain was self-reported by 8379 (15.5%) participants at follow-up. After adjusting for covariates, deployers with combat experiences had higher odds [odds ratio (OR) = 1.38, 95% confidence interval (95% CI): 1.28-1.50] of recent back pain than noncombat deployers. There was no association between recent back pain and nondeployers compared with noncombat deployers. Service support/supply handlers were at an increased odds of reporting recent back pain (OR = 1.11, 95% CI: 1.02-1.21) than functional support/administration occupations. Occupations associated with a physically demanding work environment had a higher risk of back pain. Conclusion. Deployers with combat experiences were more likely to report back pain postdeployment. This well-defined group of military personnel may potentially benefit from integrated prevention efforts.

TI A population-based epidemiologic study of adult-onset narcolepsy incidence and associated risk factors, 2004-2013 SO JOURNAL OF THE NEUROLOGICAL SCIENCES LA English DT Article DE Narcolepsy; Incidence; Epidemiology; Excessive daytime sleepiness; Pandemic H1N1; Autoimmunity ID MULTIPLE-SCLEROSIS; VITAMIN-D; INFLUENZA; CATAPLEXY; VIRUS AB An increase in narcolepsy incidence was noted after the novel pandemic influenza of 2009, leading to further interest in risk factors associated with this disease. However, there is limited data on the epidemiology of narcolepsy, particularly in the adult population. Therefore, we sought to examine narcolepsy incidence rates in the United States and describe associated characteristics. We performed a population based epidemiologic study of active duty military personnel. All outpatient clinics in the continental United States providing care for active duty military between 2004 through 2013 were included utilizing existing databases. Narcolepsy was defined in 3 ways: (1) 2 diagnoses of narcolepsy within 6 months of each other, one made by a sleep expert; (2) 2 diagnoses by any provider followed by a narcolepsy prescription within 14 days of last visit; and (3) procedure code for a sleep study followed by a narcolepsy diagnosis by a sleep expert within 6 months. There were 1675 narcolepsy cases. Overall incidence of narcolepsy trended from 14.6 to 27.3 cases per 100,000 person-years, with an increase starting after 2005-2006 and peaking during the 2011-2012 influenza season. Higher frequencies were seen among females, non-Hispanic blacks, and members living in the south. Narcolepsy incidence rates among active duty military members are higher than previously described. The reason for the steady rise of incidence from 2005 to 2006 through 2011-2012 is unknown; however, these findings require further exploration. We detected risk factors associated with the development of narcolepsy which may aid in future study efforts. Published by Elsevier B.V.

The legislation mandated the Department of Defense (DoD) and Department of Veterans Affairs (VA) to implement a comprehensive plan and strategy for the mitigation, treatment, and rehabilitation of traumatic extremity injuries and amputation. The EACE also was tasked with conducting clinically relevant research, fostering collaborations, and building partnerships across multidisciplinary international, federal, and academic networks to optimize the quality of life of service members and veterans who have sustained extremity trauma or amputations. To fulfill themandate to conduct research, the EACE developed a Research and Surveillance Division that complements and collaborates with outstanding DoD, VA, and academic research programs across the globe. The EACE researchers have efforts in four key research focus areas relevant to extremity trauma and amputation: (1) Novel Rehabilitation Interventions, (2) Advanced Prosthetic and Orthotic Technologies, (3) Epidemiology and Surveillance, and (4) Medical and Surgical Innovations. This overview describes the EACE efforts to innovate, discover, and translate knowledge gleaned from collaborative research partnerships into clinical practice and policy.

TI Descriptive Characteristics and Amputation Rates With Use of Intrepid Dynamic Exoskeleton Orthosis SO MILITARY MEDICINE LA English DT Article ID OPERATION ENDURING FREEDOM; LOWER-EXTREMITY TRAUMA; IRAQI FREEDOM; INJURY; RETURN; WOUNDS; DUTY AB Advancements in ankle-foot orthotic devices, such as the Intrepid Dynamic Exoskeletal Orthosis (IDEO), are designed to improve function and reduce pain of the injured lower extremity. There is a paucity of research detailing the demographics, injury patterns and amputation outcomes of patients who have been prescribed an IDEO. The purpose of this study was to describe the demographics, presenting diagnosis and patterns of amputation in patients prescribed an IDEO at the Center for the Intrepid (CFI). The study population was comprised of 624 service members who were treated at the CFI and prescribed an IDEO between 2009 and 2014. Data were extracted from the Expeditionary Medical Encounter Database, Defense Manpower Data Center, Military Health System Data Repository, and CFI patient records for demographic and injury information as well as an amputation outcome. The most common injury category that received an IDEO prescription was injuries at or surrounding the ankle joint (25.0%), followed by tibia injuries (17.5%) and nerve injuries below the knee (16.4%). Over 80% of the sample avoided amputation within a one year time period using this treatment modality. Future studies should longitudinally track IDEO users for a longer term to determine the long term viability of the device.

However, CAR research is routinely challenged by its innate complexity, sensitivity to confounds, and methodological inconsistencies. In this unprecedented characterization of CAR in elite military men (N = 58), we established summary parameters, evaluated sampling stability across two consecutive days, and explored the effect of subject compliance. Average salivary cortisol concentrations increased nearly 60% within 30 minutes of waking, followed by a swift recovery to waking values at 60 minutes. Approximately one in six were classified as negative responders (i.e., < 0% change from waking to 30-minute postawakening). Three summary parameters of magnitude, as well as three summary parameters of pattern, were computed. Consistent with our hypothesis, summary parameters of magnitude displayed superior stability compared with summary parameters of pattern in the total sample. As expected, compliance with target sampling times was relatively good; average deviations of self-reported morning sampling times in relation to actigraph-derived wake times across both days were within +/- 5 minutes, and nearly two-thirds of the sample was classified as CAR compliant across both days. Although compliance had equivocal effects on some measures of magnitude, it substantially improved the stability of summary parameters of pattern. The first of its kind, this study established the foundation for a program of CAR research in a profoundly resilient yet chronically stressed population. Building from this, our forthcoming research will evaluate demographic, biobehavioral, and clinical determinants of CAR in this unique population.

Results: The strongest predictors of early attrition because of drug use were being a smoker, African American race, moving around often as a child, not having a high school diploma, joining the military to leave problems behind, and having a prior arrest record. The results also indicate that approximately 3.1 million person-days were lost in this cohort because of early discharge for drug abuse. Conclusions: Despite effective policies that prohibit drug use, these findings suggest that a significant loss in manpower and training costs still occurs because of early attrition for drug use. Postenlistment interventions for those recruits at higher risk for drug abuse may help to reduce this attrition.

Both spherical polystyrene beads and a commercial antacid are used to determine the effect of scattering particle size and shape on the results. Varying concentrations of the scattering agents were used to study the propagation of light in both minimally scattered and multiply scattered regimes (over 20 attenuation lengths). To study temporal dispersion, a custom diode seeded fiber amplified laser source is used to modulate beams up to 1 GHz, and diffractive spiral phase plates are used to compare performance over different spatial modes. We observe an increase in received signal with increasing OAM order (vertical bar m vertical bar = 0, 8, and 16) under multiple scattering conditions. Initial experimental results suggest that this variation is dependent on particle shape and size. We do not observe any dependency of OAM order on temporal dispersion.

TI Independent component analysis for enhancement of an FMCW optical ranging technique in turbid waters SO APPLIED OPTICS LA English DT Article AB Optical detection and ranging in turbid waters are challenged by the effects of absorption and scattering. In particular, backscatter creates a clutter return, which can mask the presence of weak underwater targets. This work explores the use of independent component analysis (ICA), a statistical signal processing approach, to recover weak targets from strong backscatter in turbid waters using a frequency-modulated continuous-wave optical rangefinder. ICA uses statistical differences between target and backscatter returns to suppress the backscatter return. In laboratory test tank experiments, the use of ICA is observed to improve probability of detection at various turbidities and extend target detection range by four optical attenuation lengths.

However, detecting mTBI using conventional clinical techniques is difficult, time intensive, and subject to observer bias. We examine the use of a simple visuomotor tracking task as a screening tool for mTBI. Thirty participants, 16 with clinically diagnosed mTBI (mean time since injury: 36.4 +/- A 20.9 days (95 % confidence interval); median = 20 days) were asked to squeeze a hand dynamometer and vary their grip force to match a visual, variable target force for 3 min. We found that controls outperformed individuals with mTBI; participants with mTBI moved with increased variability, as quantified by the standard deviation of the tracking error. We modeled participants' feedback response-how participants changed their grip force in response to errors in position and velocity-and used model parameters to classify mTBI with a sensitivity of 87 % and a specificity of 93 %, higher than several standard clinical scales. Our findings suggest that visuomotor tracking could be an effective supplement to conventional assessment tools to screen for mTBI and track mTBI symptoms during recovery.

This study examined the reciprocal relationships between psychological symptoms and stressful life events over time among veterans of Operations Iraqi Freedom and Enduring Freedom. Service members (N = 1,599) completed surveys when separating from service and approximately one year later. Surveys assessed demographic characteristics, impulsivity, combat exposure, noncombat-related stressful life events, and symptoms of PTSD, depression, and substance abuse. Structural equation modeling showed that both depression and PTSD symptoms predicted future stressful life events; this relationship was fully mediated by substance abuse for depression, but not for PTSD symptoms. Consistent with some previous research, noncombat stressors showed stronger and more pervasive effects on mental health symptoms than did combat exposure. Impulsivity emerged as a shared vulnerability factor for depression, PTSD, substance use, and stressful experiences. Prior to and following separation, service members should receive interventions to improve their response to stressful life events, including coping skills and substance abuse prevention training.

This cross-sectional study examined caffeine use in Navy and Marine Corps personnel, including prevalence, amount of daily consumption, and factors associated with use. A random sample of Navy and Marine Corps personnel was contacted and asked to complete a detailed questionnaire describing their use of caffeine-containing substances, in addition to their demographic, military, and lifestyle characteristics. A total of 1708 service members (SMs) completed the questionnaire. Overall, 87% reported using caffeinated beverages >= 1 time/week, with caffeine users consuming a mean +/- standard error of 226 +/- 5 mg/day (242 +/- 7 mg/day for men, 183 +/- 8 mg/day for women). The most commonly consumed caffeinated beverages (% users) were coffee (65%), colas (54%), teas (40%), and energy drinks (28%). Multivariable logistic regression modeling indicated that characteristics independently associated with caffeine use (>= 1 time/week) included older age, white race/ethnicity, higher alcohol consumption, and participating in less resistance training. Prevalence of caffeine use in these SMs was similar to that reported in civilian investigations, but daily consumption (mg/day) was higher.

TI Characterizing rapid capacity fade and impedance evolution in high rate pulsed discharged lithium iron phosphate cells for complex, high power loads SO JOURNAL OF POWER SOURCES LA English DT Article DE Pulsed power systems; Lithium-ion; High rate cycling; Electrochemical impedance spectroscopy; Surface films ID RAY-ABSORPTION SPECTROSCOPY; ION BATTERIES; ELECTROCHEMICAL IMPEDANCE; INTERCALATION; ELECTRODES; TRANSITION; GRAPHITE; RAILGUN; IFEFFIT; MODELS AB Three 26650 LiFePO4 (LFP) cells are cycled using a 40 A pulsed charge/discharge profile to study their performance in high rate pulsed applications. This profile is used to simulate naval pulsed power loads planned for deployment aboard future vessels. The LFP cells studied experienced an exponential drop in their usable high-rate recharge capacity within sixty cycles due to a rapid rise in their internal resistance. Differential capacitance shows that the voltage window for charge storage is pushed outside of the recommended voltage cutoff limits. Investigation into the state of health of the electrodes shows minimal loss of active material from the cathode to side reactions. Post-mortem examination of the anodic surface films reveals & large increase in the concentration of reduced salt compounds indicating that the pulsed profile creates highly favorable conditions for LiPF6 salt to break down into LiF. This film slows the ionic movement at the interface, affecting transfer kinetics, resulting in charge buildup in the bulk anode without successful energy storage. The results indicate that the use of these cells as a power supply for high pulsed power loads is hindered because of ionically resistant film development and not by an increasing rate of active material loss.

Jeff TI Development and analysis of a lithium carbon monofluoride battery-lithium ion capacitor hybrid system for high pulse-power SO JOURNAL OF POWER SOURCES LA English DT Article DE Hybrid; Lithium ion capacitor; Li/CFxMnO2 battery ID DISCHARGE REACTION; PERFORMANCE; CELL; DEVICES; CATHODE; ENERGY; LOADS AB Although Li/CFx and Li/CFxMnO2 have two of the highest energy densities of all commercial lithium primary batteries known to date, they are typically current-limited and therefore are not used in high power applications. In this work, a Li/CFxMnO2 battery (BA-5790) was hybridized with a 1000 F lithium ion capacitor to allow its use for portable electronic devices requiring 100 W 1-min pulses. An intelligent, power-management board was developed for managing the energy flow between the components. The hybrid architecture was shown to maintain the battery current to a level that minimized energy loss and thermal stress. The performance of the Li/CFxMnO(2) hybrid was compared to the standard Li/SO2 battery (BA-5590). The hybrid was shown to deliver the same number of 100 W pulse cycles as two BA-5590 batteries, resulting in a weight savings of 30% and a volumetric reduction of 20%. For devices requiring 8 h of operational time or less, a 5-cell Li/CFxMnO2 hybrid was found to be a lighter (55%) and smaller (45%) power source than the existing two BA-5590 battery option, and a lighter (42%) and smaller (27%) option than 1 1/2 BA-5790 batteries alone. At higher power requirements (>100 W), further weight and size improvements can be expected. (C) 2016 Published by Elsevier B.V.

TI Vitamin D levels and influenza vaccine immunogenicity among HIV-infected and HIV-uninfected adults SO VACCINE LA English DT Article DE Influenza vaccine; HIV-infected persons; Vitamin D level; Immunogenicity ID MUCOSAL IMMUNE-RESPONSES; D DEFICIENCY; D SUPPLEMENTATION; 1,25-DIHYDROXYVITAMIN D-3; HIV-1-INFECTED PATIENTS; RANDOMIZED-TRIAL; UNITED-STATES; EFFICACY; IMMUNIZATION; MORTALITY AB Background: Vaccination is the most important preventive strategy against influenza, however post-vaccination antibody responses are often inadequate especially among HIV-infected persons. Vitamin D deficiency has been suggested to adversely influence immune responses and is highly prevalent among HIV-infected adults. Therefore, we evaluated the association between 25-hydroxyvitamin D [25(OH)D] levels and post-influenza vaccination responses. Methods: We conducted a prospective cohort study evaluating the immunogenicity of monovalent influenza A (H1N1) vaccination among both HIV-infected and HIV-uninfected adults (18-50 years of age) during the 2009-2010 influenza season. Antibody titers were evaluated at baseline, day 28, and 6 months post-vaccination using hemagluttination inhibition assays. Serum 25(OH)D levels were measured at day 28. Univariate and multivariate regression analyses examined the association between 25(OH)D levels [categorized as <20 ng/ml (deficiency) vs. >= 20 ng/ml]with the primary outcome of seroconversion. Secondary outcomes included seroprotection; a >= 4-fold increase in titers; and geometric mean titers post-vaccination. Analyses were repeated using 25(OH)D levels as a continuous variable. Results: A total of 128 adults [64 HIV-infected (median CD4 count 580 cells/mm(3)) and 64 HIV-uninfected] were included. Seroconversion at day 28 post-vaccination was achieved in fewer HIV- infected participants compared with HIV-uninfected participants (56% vs. 74%, p = 0.03). Vitamin D deficiency was more prevalent among HIV-infected persons vs. HIV-uninfected persons (25% vs. 17%), although not significantly different (p = 0.39). There were no associations found between lower 25(OH) D levels and poorer antibody responses at day 28 or 6 months for any of the study outcomes among either HIV-infected or HIV-uninfected adults. Conclusion: Vitamin D deficiency was common among both HIV-infected and HIV-uninfected adults, but lower levels did not predict antibody responses after H1N1 (2009) influenza vaccination. Low 25(OH)D levels do not explain poorer post-vaccination responses among HIV-infected persons. (C) 2016 Elsevier Ltd. All rights reserved.

TI Type-specific clinical characteristics of adenovirus-associated influenza-like illness at five US military medical centers, 2009-2014 SO INFLUENZA AND OTHER RESPIRATORY VIRUSES LA English DT Article DE Adenovirus; influenza-like illness; military ID CHILDREN; INFECTIONS; EPIDEMIOLOGY; OUTBREAK; SEROTYPE; DISEASE AB Background Adenovirus is a recognized cause of influenza-like illness (ILI). The proportion of ILI attributable to adenovirus is not known. Moreover, knowledge gaps remain with respect to the epidemiologic, virologic, and clinical characteristics of adenovirus-associated ILI among otherwise healthy individuals. Methods An observational, longitudinal study of <65-year-old patients with febrile ILI at five medical centers was conducted from 2009 to 2014. Nasopharyngeal specimens obtained at enrollment were first tested by single-reaction PCR for adenovirus, then further evaluated by a multiplex PCR assay for other respiratory viral pathogens. Symptoms over a 28-day period were collected. Results We enrolled 1536 individuals, among whom 43 (2.8%) were positive for adenovirus. The median age of cases was 3.4 years (range: 4 months to 41 years). Three were hospitalized. Species and serotype information was available for 33 (76.7%) cases. Species C (n = 21) was the most common, followed by B3 (n = 9) and one each of E4a, D46, and A. Species C infections were more frequent in children (P < 0.01). Half of the cases were positive for at least one other respiratory viral pathogen. Symptoms were generally mild and most commonly included cough (90%), fatigue (79%), rhinorrhea (74%), loss of appetite (71%), and sore throat (64%). Children with non-C adenovirus infection were more likely to report sore throat (P = 0.05) and hoarseness (P = 0.06) than those with species C infection. Conclusions Adenovirus is frequently detected with other respiratory viruses. Persons with non-C adenovirus infections reported more severe symptoms, suggesting there may be species-specific differences in virulence and/or host response to infection.

Five types of pesticide sprayers, representing 3 spray technologies (1 mister, 2 ultra-low volume [ULV] cold foggers, and 2 ULV thermal foggers), were evaluated for their ability to control adult and immature stages of Ae. aegypti in indoor and outdoor environments. Cages holding adult mosquitoes and larvae were placed in cryptic sites for indoor sprays and placed among dense vegetation for outdoor sprays. Adult and pupal mortality data were recorded following applications of a mixture of synergized pyrethrins and pyriproxyfen. We found that no single sprayer was best suited for controlling Ae. aegypti in indoor and outdoor environments, nor was one best for controlling adult and immature mosquitoes. Sprayers producing larger droplets (misters and cold foggers) were more effective in controlling immature mosquitoes indoors and outdoors. Thermal fogging was more effective in controlling adults indoors, whereas cold fogs and misters were more effective for outdoor control.

TI Effect of Cadmium Plating Thickness on the Charpy Impact Energy of Hydrogen-Charged 4340 Steel SO JOURNAL OF MATERIALS ENGINEERING AND PERFORMANCE LA English DT Article DE 4340 steel; cadmium plating; Charpy impact test; hydrogen charging ID MECHANICAL-PROPERTIES; INDUCED CRACKING; EMBRITTLEMENT; TRANSPORT; BEHAVIOR; FRACTURE; MICROSTRUCTURE; DEFORMATION AB Hydrogen was intentionally introduced into ultra-high strength steel by cadmium plating. The purpose was to examine the effect of cadmium plate thickness and hence hydrogen on the impact energy of the steel. The AISI 4340 steel was austenitized at 1000 A degrees C for 1 h, water quenched, and tempered at temperatures between 257 and 593 A degrees C in order to achieve a range of targeted strength levels. The specimens were cadmium plated with 0.00508 mm (0.2 mils), 0.00762 mm (0.3 mils), and 0.0127 mm (0.5 mils). Results demonstrated that the uncharged specimens exhibited higher impact energy values when compared to the plated specimens at all tempering temperatures. The cadmium-plated specimens had very low Charpy impact values irrespective of their ultimate tensile strength values. The model of hydrogen transport by mobile dislocations to the fracture site appears to provide the most suitable explanation of the results. C1 [Es-Said, O.

TI Prevalence, Adverse Events, and Factors Associated with Dietary Supplement and Nutritional Supplement Use by US Navy and Marine Corps Personnel SO JOURNAL OF THE ACADEMY OF NUTRITION AND DIETETICS LA English DT Article DE Vitamin; Mineral; Prohormone; Sport drinks; Sport bars/gels ID ACUTE LIVER-INJURY; WEIGHT-LOSS; UNITED-STATES; GENDER-DIFFERENCES; NATIONAL-HEALTH; NO-XPLODE; CARE UTILIZATION; ACUTE HEPATITIS; OXYELITE PRO; HYDROXYCUT AB Background About 50% of Americans and 60% to 70% of US military personnel use dietary supplements, some of which have been associated with adverse events (AEs). Nutritional supplements like sport drinks and sport bars/gels are also commonly used by athletes and service members. Previous dietary supplement and nutritional supplement surveys were conducted on Army, Air Force, and Coast Guard personnel. Objective The aim of this cross-sectional study was to investigate dietary and nutritional supplement use in Navy and Marine Corps personnel, including the prevalence, types, factors associated with use, and AEs. Design A random sample of 10,000 Navy and Marine Corps personnel were contacted. Service members were asked to complete a detailed questionnaire describing their personal characteristics, supplement use, and AEs experienced. Results In total, 1,708 service members completed the questionnaire during August through December 2014, with 1,683 used for analysis. Overall, 73% reported using dietary supplements one or more times per week. The most commonly used dietary supplements (used one or more times per week) were multivitamins/multiminerals (48%), protein/amino acids (34%), combination products (33%), and individual vitamins and minerals (29%). About 31% of service members reported using five or more dietary supplements. Sport drinks and sport bars/gels were used by 45% and 23% of service members, respectively. Monthly expenditures on dietary supplements averaged $39; 31% of service members spent >=$50/mo. Multivariate logistic regression modeling indicated that female sex (women/men; odds ratio [OR]=1.76, 95% CI 1.32 to 2.36), higher educational level (college degree/no college degree; OR=2.23, 95% CI 1.62 to 3.30), higher body mass index (calculated as kg/m(2)) (>= 30/<25; OR=1.67, 95% CI 1.06 to 2.63), and a greater amount of resistance training (>= 271/0 to 45 min/week; OR=2.85, 95% CI 1.94 to 4.17) were associated with dietary supplement use. Twenty-two percent of dietary supplement users and 6% of nutritional supplement users reported one or more AEs. For combination products alone, 29% of users reported one or more AEs. Conclusions The prevalence of dietary supplement use in Navy and Marine Corps personnel was considerably higher than reported in civilian investigations for almost all types of dietary supplements, although similar to most other military services. Factors associated with dietary supplement use were similar to those reported in previous military and civilian investigations. Prevalence of self-reported AEs was very high, especially for combination products.

TI Appendage Drag Prediction on Submerged Axisymmetric Bodies SO JOURNAL OF SHIP RESEARCH LA English DT Article DE hydrodynamics (general); resistance (general); boundary layer ID BODY JUNCTION; FILLET AB A new appendage resistance prediction method, which mitigates the technical issues with the existing test procedure, has been developed and presented in this paper. The primary aspects of the new method are 1) the Froude's equivalent flat plate friction drag concept extensively used in the marine industry will not be used in the present method, instead, an aerodynamic profile drag concept for resistance prediction is presented, 2) the turbulent stimulators extensively used in existing model appendage resistance tests will not be used in the proposed test procedure, which eliminates the need for high-speed tests and the problematic issue of estimating the parasitic drag associated with turbulence stimulators, 3) the important juncture vortex drag associated with appendages is considered, 4) the effective velocity entering the stern appendages on resistance is considered, 5) the new scaling formula to relate model profile drag and juncture vortex drag to full-scale appendage drag is developed and presented in this paper.

These were characterized by mass spectrometry, anion photoelectron spectroscopy, and density functional theory based calculations. Agreement between the experimentally and theoretically determined vertical detachment energies and adiabatic detachment energies validated the computed geometrical structures. Reactions between aluminum hydride cluster anions and ligands provide a new avenue for discovering low oxidation state, ligated aluminum clusters. Published by AIP Publishing.

Many emergency department (ED) patients may not routinely seek care elsewhere. In a survey of ED visitors, 36.8% of unvaccinated respondents were willing to consider influenza vaccination during their visit. Participants at high risk for influenza complications were more likely to have been previously vaccinated, but unvaccinated participants at high risk were not significantly more likely to consider ED-based vaccination compared with other participants. ED-based influenza vaccination may be an effective method to expand vaccine coverage.

METHODS: Patients with amputation in Iraq or Afghanistan from 2009 through 2011 were eligible. Details of postinjury care, date of diagnosis of DVT/PE, and injury specific data were collected. Military databases and chart reviews were used. RESULTS: In 366 patients, 103 (28%) had DVT/PE; PE was diagnosed in 59 (16%) and DVT in 59 (16%). Most DVT (69%) and PE (66%) occurred within 10 days. Increasing ventilator days (odds ratio [OR], 1.97; 95% CI, 1.16 to 3.37) and units of blood transfused (OR, 1.72; 95% CI, 1.11 to 2.68) were associated with DVT. Increasing units of fresh-frozen plasma were associated with PE (OR, 1.31; 95% CI, 1.10 to 1.55). CONCLUSIONS: The incidence of DVT/PE is high after combat-related amputation. Most DVT/PE occur early and prophylaxis is indicated. Published by Elsevier Inc.

TI Immune Responses in US Military Personnel Who Received Meningococcal Conjugate Vaccine (MenACWY) Concomitantly with Other Vaccines Were Higher than in Personnel Who Received MenACWY Alone SO CLINICAL AND VACCINE IMMUNOLOGY LA English DT Article ID NEISSERIA-MENINGITIDIS SEROGROUP; DIPHTHERIA-TETANUS-PERTUSSIS; SERUM BACTERICIDAL ASSAYS; UNITED-STATES MILITARY; GROUP-C; ANTIBODY CONCENTRATIONS; INFLUENZA VACCINE; B VACCINE; GROUP-A; IMMUNOGENICITY AB Immunological responses to vaccination can differ depending on whether the vaccine is given alone or with other vaccines. This study was a retrospective evaluation of the immunogenicity of a tetravalent meningococcal conjugate vaccine for serogroups A, C, W, and Y (MenACWY) administered alone (n = 41) or concomitantly with other vaccines (n = 279) to U.S. military personnel (mean age, 21.6 years) entering the military between 2006 and 2008. Concomitant vaccines included tetanus/diphtheria (Td), inactivated polio vaccine (IPV), hepatitis vaccines, and various influenza vaccines, among others; two vaccine groups excluded Tdap and IPV. Immune responses were evaluated in baseline and postvaccination sera for Neisseria meningitidis serogroups C and Y 1 to 12 months (mean, 4.96 months) following vaccination. Functional antibodies were measured by using a serum bactericidal antibody assay with rabbit complement (rSBA) and by measurement of serogroup- specific immunoglobulin G (IgG) antibodies. The percentage of vaccinees reaching threshold levels (IgG concentration in serum, >= 2 = mu g/ml; rSBA titer, >= 8) corresponding to an immunologic response was higher postvaccination than at baseline (P < 0.001). Administration ofMenACWYalong with other vaccines was associated with higher geometric means of IgG concentrations and rSBA titers than those measured 4.60 months after a single dose of Men ACWY. In addition, higher percentages of vaccinees reached the immunological threshold (range of odds ratios [ORs], 1.5 to 21.7) and more of them seroconverted (OR range, 1.8 to 4.8) when Men ACWY was administered with any other vaccine than when administered alone. Additional prospective randomized clinical trials are needed to confirm the observed differences among groups in the immune response to Men ACWY when given concomitantly with other vaccines to U.S. military personnel.

TI Pre-deployment Alcohol Misuse Among Shipboard Active-Duty US Military Personnel SO AMERICAN JOURNAL OF PREVENTIVE MEDICINE LA English DT Article ID BINGE-DRINKING; AUDIT-C; COLLEGE-STUDENTS; PRIMARY-CARE; HEALTH; RISK; POPULATION; CONSUMPTION; PREVALENCE; DISORDERS AB Introduction: The burden of alcohol misuse is unknown among shipboard U.S. Navy and Marine Corps military personnel immediately prior to deployment and may be elevated. Methods: Anonymous survey data on hazardous, dependent, and binge alcohol misuse and involuntary drug consumption were collected during 2012-2014 among shipboard personnel within approximately 2 weeks of deployment. Using the Alcohol Use Disorders Identification Test Consumption (AUDIT-C), hazardous alcohol misuse was defined using two cut-point scoring criteria: (1) >= 3 for women and >= 4 for men; and (2) >= 4 for women and >= 5 for men; binge drinking as >= 4 drinks for women and >= 5 drinks for men on a typical day in past 30 days; and dependent alcohol misuse as an AUDIT-C score of >= 8. Demographic-and sex-stratified self-reported alcohol misuse prevalence was reported for analysis conducted during 2014-2015. Results: Among 2,351 male and female shipboard personnel, 39%-54% screened positive for hazardous, 27% for binge, and 15% for dependent alcohol use. Seven percent reported involuntary drug consumption history. A larger proportion of those aged 17-20 years screened positive for dependent alcohol use compared with the overall study population prevalence. Conclusions: A large proportion of shipboard personnel screened positive for hazardous and dependent alcohol use (18% among those aged <21 years) at deployment onset. These data can inform interventions targeting shipboard personnel engaging in hazardous use before progression to dependent use and enable early identification and care for dependent users. Future studies should include more comprehensive assessment of factors associated with involuntary drug consumption. (C) 2016 American Journal of Preventive Medicine. Published by Elsevier Inc.

JIT-ADM is a novel asynchronous parallel programming pattern that unifies various levels of asynchronous concurrency available with distributed heterogeneous computing. The computational performance of this DSB algorithm was analyzed on a 50 node Cray XC30 with a single 10-core Intel Xeon E5-2670 v2 and NVIDIA Tesla K20X general purpose Graphics Processing Unit (GPU) on each node. The algorithm exhibits well behaved weak scalability with 92.7 percent parallel efficiency at 50 nodes compared to maximum performance observed. It is also shown that the algorithm efficiently utilizes a large portion of the available hardware. During beamforming the GPU is utilized at 51.8 percent of its maximum double precision floating point throughput whereas a comparable Central Processing Unit (CPU) version utilizes 60.0 percent of its maximum expected floating point throughput. Across the weak scalability study, utilizing GPUs for processing, a 2-5x performance gain is achieved compared to using CPUs. A brief derivation and validation of the implemented DSB is also presented. C1 [Sarofeen, Christian] Naval Surface Warfare Ctr, Computat Anal & Design, Carderock Div, West Bethesda, MD 20817 USA.

The methodology was to investigate how different material property assumptions in a simulation affect meltpool prediction and by corrolary how different material properties affect meltpool formation in AM processes. The sensitvity of meltpool variations to each material property can be used as a guide to help drive future research and to help prioritize material specifications in requirements documents. By identifying which material properties have the greatest affect on outcomes, metrology can be tailored to focus on those properties which matter most; thus reducing costs by eliminating unnecessary testing and property charaterizations. Futhermore, this sensitivity study provides insight into which properties require more accurate measurements, thus motivating development of new metrology methods to measure those properties accurately.

The method modifies the derivative of a perfect antireflective wave amplitude distribution rather than the index of refraction distribution. Modifying the derivative of the wave amplitude distribution minimizes the potential index of refraction distributions and ensures perfect antireflection at one frequency, incidence angle, and linear polarization combination. Additional combinations of frequency, incident angle, and linear polarization can be targeted at a particular reflection coefficient within the optimization. After the method is outlined, three examples are shown with one being fabricated and validated at radiofrequencies.

Reed, Jason Stegman, Peter Bock, Naomi TI Assessing Progress, Impact, and Next Steps in Rolling Out Voluntary Medical Male Circumcision for HIV Prevention in 14 Priority Countries in Eastern and Southern Africa through 2014 SO PLOS ONE LA English DT Article ID COSTS AB Background In 2007, the World Health Organization and the Joint United Nations Programme on HIV/AIDS (UNAIDS) identified 14 priority countries across eastern and southern Africa for scaling up voluntary medical male circumcision (VMMC) services. Several years into this effort, we reflect on progress. Methods Using the Decision Makers' Program Planning Tool (DMPPT) 2.1, we assessed age-specific impact, cost-effectiveness, and coverage attributable to circumcisions performed through 2014. We also compared impact of actual progress to that of achieving 80% coverage among men ages 15-49 in 12 VMMC priority countries and Nyanza Province, Kenya. We populated the models with age-disaggregated VMMC service statistics and with population, mortality, and HIV incidence and prevalence projections exported from country-specific Spectrum/Goals files. We assumed each country achieved UNAIDS' 90-90-90 treatment targets. Results More than 9 million VMMCs were conducted through 2014: 43% of the estimated 20.9 million VMMCs required to reach 80% coverage by the end of 2015. The model assumed each country reaches the UNAIDS targets, and projected that VMMCs conducted through 2014 will avert 240,000 infections by the end of 2025, compared to 1.1 million if each country had reached 80% coverage by the end of 2015. The median estimated cost per HIV infection averted was $4,400. Nyanza Province in Kenya, the 11 priority regions in Tanzania, and Uganda have reached or are approaching MC coverage targets among males ages 15-24, while coverage in other age groups is lower. Across all countries modeled, more than half of the projected HIV infections averted were attributable to circumcising 10- to 19-year-olds. Conclusions The priority countries have made considerable progress in VMMC scale-up, and VMMC remains a cost-effective strategy for epidemic impact, even assuming near-universal HIV diagnosis, treatment coverage, and viral suppression. Examining circumcision coverage by five-year age groups will inform countries' decisions about next steps. C1 [Kripke, Katharine; Stegman, Peter] Avenir Hlth, Project SOAR, Washington, DC USA.

TI Influenza vaccine effectiveness: Maintained protection throughout the duration of influenza seasons 2010-2011 through 2013-2014 SO VACCINE LA English DT Article DE Vaccine effectiveness; Influenza; Postvaccination; Age groups ID ELDERLY POPULATION; IMMUNE-RESPONSE; PERSISTENCE; IMPACT AB Background: Factors, such as age, comorbidities, vaccine type, herd immunity, previous influenza exposure, and antigenic shift may impact the immune response to the influenza vaccine, protection against circulating strains, and antibody waning. Evaluating vaccine effectiveness (VE) is important for informing timing of vaccine administration and evaluating overall vaccine benefit. Methods: VE was assessed using febrile respiratory illness surveillance among Department of Defense non active duty beneficiaries from influenza seasons 2010-2011 through 2013-2014. Respiratory specimens were taken from participants meeting the case definition and tested by polymerase chain reaction for influenza. VE was calculated using logistic regression and by taking 1 minus the odds ratio of being vaccinated in the laboratory confirmed positive influenza cases versus laboratory confirmed negative controls. Results: This study included 1486 participants. We found an overall adjusted VE that provided significant and fairly consistent protection ranging from 54% to 67% during 0-180 days postvaccination. This VE dropped to -11% (95% confidence interval: -102% to 39%) during 181-365 days. Conclusions: Our study found moderate VE up to 6 months postvaccination. Since the influenza season starts at different times each year, optimal timing is difficult to predict. Consequently, early influenza vaccination may still offer the best overall protection.

TI Organic Crystal Engineering of Thermosetting Cyanate Ester Monomers: Influence of Structure on Melting Point SO CRYSTAL GROWTH & DESIGN LA English DT Article ID 4 PHENYLENE RINGS; POLYCYANURATE BLENDS; PHYSICAL-PROPERTIES; BISPHENOL-A; RESINS; DICYANATE; NETWORKS; POLYMERIZATION; STABILITY; LIQUID AB Key principles needed for the rational design of thermosetting monomer crystals, in order to control the melting point, have been elucidated using both theoretical and experimental investigations of cyanate esters. A determination of the thermodynamic properties associated with melting showed that the substitution of silicon for the central quaternary carbon in the di(cyanate ester), 2,2-bis(4-cyanatophenyl)propane, resulted in an increase in the entropy of melting along with a decrease in the enthalpy of melting, leading to a decrease in the melting temperature of 21.8 +/- 0.2 K. In contrast, the analogous silicon substitution in the tri(cyanate ester), 1,1,1-tris(4-cyanatophenyl)ethane, resulted in no significant changes to the enthalpy and entropy of melting, accompanied by a small increase of 1.5 +/- 0.3 K in the melting point. The crystal structure of 1,1,1-tris(4-cyanatophenyl)ethane was determined via single crystal X-ray diffraction, and the structures of these four di(cyanate esters) and tri(cyanate esters) were examined. Although both the empirical models of Lian and Yalkowsky, as well as Chickos and Acree, provided reasonable estimates of the entropy of melting of 2,2-bis(4-cyanatophenyl)propane, they successfully predicted only certain effects of silicon substitution and did not capture the difference in behavior between the di(cyanate esters) and the tri(cyanate esters). Semiempirical molecular modeling, however, helped to validate an explanation of the mechanism for the increase in the entropy of melting of the silicon-containing di(cyanate ester), while providing insight into the reason for the difference in behavior between the di(cyanate esters) and tri(cyanate esters). Taken together, the results assist in understanding how freedom of molecular motions in the liquid state may control the entropy of melting and can be utilized to guide the development of compounds with optimal melting characteristics for high-performance applications.

TI Longitudinal Associations Among Posttraumatic Stress Disorder, Disordered Eating, and Weight Gain in Military Men and Women SO AMERICAN JOURNAL OF EPIDEMIOLOGY LA English DT Article DE binge eating; eating disorders; military; obesity ID COMORBIDITY SURVEY-REPLICATION; MILLENNIUM COHORT; ADULT OBESITY; US MILITARY; HEALTH; PREVALENCE; QUESTIONNAIRE; PREDICTORS; ENROLLMENT; VETERANS AB Obesity is a major health problem in the United States and a growing concern among members of the military. Posttraumatic stress disorder (PTSD) has been associated with overweight and obesity and may increase the risk of those conditions among military service members. Disordered eating behaviors have also been associated with PTSD and weight gain. However, eating disorders remain understudied in military samples. We investigated longitudinal associations among PTSD, disordered eating, and weight gain in the Millennium Cohort Study, which includes a nationally representative sample of male (italic toggle="yes"n = 27,741) and female (italic toggle="yes"n = 6,196) service members. PTSD at baseline (time 1; 2001-2003) was associated with disordered eating behaviors at time 2 (2004-2006), as well as weight change from time 2 to time 3 (2007-2008). Structural equation modeling results revealed that the association between PTSD and weight change from time 2 to time 3 was mediated by disordered eating symptoms. The association between PTSD and weight gain resulting from compensatory behaviors (vomiting, laxative use, fasting, overexercise) was significant for white participants only and for men but not women. PTSD was both directly and indirectly (through disordered eating) associated with weight change. These results highlight potentially important demographic differences in these associations and emphasize the need for further investigation of eating disorders in military service members.

TI DsRNA-mediated targeting of ribosomal transcripts RPS6 and RPL26 induces long-lasting and significant reductions in fecundity of the vector Aedes aegypti SO JOURNAL OF INSECT PHYSIOLOGY LA English DT Article DE Aedes aegypti; Ribosome; dsRNA; siRNA; Oviposition; Fecundity; Trigger; Gene silencing ID DOUBLE-STRANDED-RNA; MOSQUITO VITELLOGENIN; GENE KNOCKDOWN; BLOOD MEAL; INTERFERENCE; EXPRESSION; DROSOPHILA; ANOPHELES; TRANSPORT; ELEGANS AB Ribosomal transcripts produce critical proteins that are involved in most cellular production processes. Targeting ribosomal transcripts has produced mortality in mites and ticks but the effect of ribosomal transcript knockdown has not been thoroughly examined in mosquitoes. We examine the effects of triggers targeting four ribosomal proteins (RP) transcripts. Although no significant mortality was observed after dsRNA microinjection and subsequent blood feeding, significant contrasts were observed on fecundity. Triggers targeting RPS6 and RPL26 effectively reduced gene expression but more importantly, reduced reproductive output by more than 96% and 91% at the first oviposition while triggers targeting RPL1 and RPS2 did not cause a reduction although gene expression was reduced. Significantly reduced fecundity continued through a second oviposition cycle in dsRPS6 and dsRPL26 cohorts, although the effect was not as strong. Relative gene expression levels confirmed specific transcript knockdown up to 20 days post-injection in mosquitoes that did not oviposit or produced reduced clutch sizes. Dissections at 36 h post-blood meal indicated defects in oocyte provisioning. The strong phenotype produced by d5RPS6 allowed us to examine the effects in various tissues as well as the dose response, trigger format, delivery method and trigger specificity in Aedes aegypti. Strong knockdown was observed in the abdomen and the ovaries. Greater than 50 ng of dsRPS6 significantly reduced fecundity but not when delivered in a sugar meal or as an siRNA. Similar bioassays with mutated d5RPS6 triggers indicates that up to three mismatches per possible siRNA are still effective in reducing fecundity. These studies indicate that while active and effective triggers can be developed for vector species, the lack of an efficient delivery method is the biggest barrier to use as a potential control method.

Methods: Data from three survey cycles (2001-2008) of the Millennium Cohort Study were used to examine the prevalence of obesity and associated health outcomes. Results: Of the 42,200 individuals, 25% were of normal weight in 2007/2008. Rates of obesity were significantly higher among veterans (32%) compared with service members (20%). Over a 7-year period, obesity rates doubled among both service members (10%-20%) and veterans (14%-32%). Participants with obesity were significantly more likely to be male, older, less educated, in the Army or Navy, and separated/retired from the military. Hypertension, diabetes, and sleep apnea were significantly more common among individuals with obesity compared with participants with normal weight (all P<0.05). Individuals with obesity also had significantly higher rates of depression and post-traumatic stress disorder than individuals with normal weight and had lower mental and physical functional scores (all P<0.05). Conclusions: These findings indicate an urgent need to enhance strategies for preventing and reducing excess weight gain within the military and veteran populations. Such strategies should aim to ensure a fit military force and promote health after military service.

TI Probing the Reaction Mechanism of Aluminum/Poly(vinylidene fluoride) Composites SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID THERMAL-DEGRADATION; COMBUSTION; NANOCOMPOSITES AB Energetic thin films with high mass loadings of nanosized components have been recently fabricated using electrospray deposition. These films are composed of aluminum nanoparticles (nAl) homogeneously dispersed in an energetic fluoropolymer binder, poly(vinylidene fluoride) (PVDF). The nascent oxide shell of the nAl has been previously shown to undergo a preignition reaction (PIR) with fluoropolymers such as polytetrafluoroethylene (PTFE). This work examines the PIR between alumina and PVDF to further explain the reaction mechanism of the Al/PVDF system. Temperature jump (T-jump) ignition experiments in air, argon, and vacuum environments showed that the nAl is fluorinated by gas phase species due to a decrease in reactivity in a vacuum. Thermogravimetric analysis coupled with differential scanning calorimetry (TGA/DSC) was used to confirm the occurrence of a PIR, and gas phase products during the PIR and fluorination of nAl were investigated with temperature jump time-of-flight mass spectrometry (T-jump TOFMS). Results show a direct correlation between the amount of alumina in the PVDF film and the relative signal intensity of hydrogen fluoride release (HF). Although the PIR between alumina and PVDF plays an important role in the Al/PVDF reaction mechanism, burn speeds of Al/PVDF films containing additional pure alumina particles showed no burn speed enhancement.

A homogeneous distribution of T-Nb2O5 nano particles in a highly conductive matrix represents a promising approach to maximize its energy and power densities. Here we report a one-step CO2 oxidation of two-dimensional (2D) Nb2CTx, a member of the MXenes family of 2D transition metal carbides, which leads to a hierarchical hybrid material with T-Nb2O5 nanoparticles uniformly supported on the surface of Nb2CTx sheets with disordered carbon. The oxidation temperature, duration, and CO2 flow rate determine the T-Nb2O5 crystallite size as well as the structure, composition, and the charge storage properties of the hybrid material. Fifty micrometer thick electrodes of the hybrid material exhibit high capacitance (330 C g(-1) and 660 mF cm(-2) at a charge-discharge time of 4 min) and good cycling performance in a nonaqueous lithium electrolyte. The charge storage kinetics are dominated by a surface-controlled process. The observed electrochemical performance is attributed to the intrinsic pseudocapacitive response and excellent energy storage capability of T-Nb2O5 coupled with the fast charge transfer pathways provided by the conductive 2D Nb2CTx sheets and the as-formed disordered carbon.

Methods: Calculated age and sex adjusted incidence rates of mental and behavioral conditions determined by validated instruments and electronic medical records. Results: Of 10,671 service members, 3,379 (32%) deployed between baseline and follow-up, of whom 49% reported combat experience. Combat deployers had highest incidence rates of post-traumatic stress disorder (PTSD) (25 cases/1,000 person-years [PY]), panic/anxiety (21/1,000 PY), and any mental disorder (34/1,000 PY). Nondeployers had substantial rates of mental conditions (11, 13, and 18 cases/1,000 PY). Among combat deployers, 12% screened positive for mental disorder, 59% binge drinking, 16% alcohol problem, 19% cigarette smoking, and 20% smokeless tobacco at follow-up. Of those with recent PTSD, 73% concurrently developed >1 incident mental or behavioral conditions. Of those screening positive for PTSD, 11% had electronic medical record diagnosis. Conclusions: U.S. service members joining during recent conflicts experienced high rates of mental and behavioral disorders. Highest rates were among combat deployers. Most cases were not represented in medical codes, suggesting targeted interventions are needed to address the burden of mental disorders among service members and Veterans.

TI Dissolvable Metal Supports for 3D Direct Metal Printing SO 3D PRINTING AND ADDITIVE MANUFACTURING LA English DT Article ID NITRIC-ACID; CORROSION; BEHAVIOR AB Additive manufacturing (AM) offers the ability to fabricate complex metallic structures and shapes in a layer-by-layer process. However, overhanging surfaces often require support structures to be fabricated and minimize thermally induced distortion. Unlike polymer AM processes, soluble sacrificial support materials have not been identified and characterized for metallic materials, and, as a result, support structures in 3D printed metals must be removed using additional machining operations. In this work, we demonstrate that sacrificial metal supports can be fabricated by taking advantage of differences in the chemical and electrochemical stability between different metals. As a demonstration, a stainless steel bridged structure with a 90 degrees overhang was fabricated using a carbon steel sacrificial support that was later removed through electrochemical etching in 41wt.% nitric acid with bubbling O-2. Open circuit potentials and potentiodynamic polarization curves were gathered to verify etch selectivity. No machining, grinding, or finishing operations were required to remove the metallic supports using this approach. This novel approach introduces new capabilities to AM that could drastically reduce the postprocessing needed for 3D printed metal components.

In this study HTPB pyrolysis is investigated using a CO2 laser as the energy source. The formulation of the solid fuel samples is systematically changed to isolate the effects of carbon black, metal fuel additives, and small amounts of oxidizer. In addition, chemical changes to the fuels including curative type and base polymer are varied. Rates of pyrolysis reaction are reported for a wide range of solid fuels applicable to ramjet application. Processes involving the sintering together of metal particles, accumulation of carbon black, and formation of a melt layer are found to affect the reaction rate. It is determined that the surface composition is the most influential factor influencing the regression rate of HTPB based fuels. (C) 2016 National Laboratory for Aeronautics and Astronautics.

Men who have sex with men (MSM) are highly vulnerable to human immunodeficiency virus (HIV) infection and more likely to migrate due to widespread stigma and discrimination in China. Their mobility complicates estimation of local MSM population sizes and the provision of HIV services, and may also contribute to the spread of HIV. Methods. Between 1 January 2008 and 31 December 2012, the visits of all individuals to the largest Chinese MSM dating website were recorded. After a predesigned de-identification procedure by the website, we analyzed Internet Protocol addresses for migration patterns. Migrants were defined as individuals who were away from their registered residence for >6 months in the last 12 months. Results. The website contained data on 794 912 MSM eligible for the study, of which 34.5% were migrants. The median age was 26 years (range, 18-61 years), and 85.5% were unmarried. Compared with nonmigrant MSM, migrants were less likely to be married to a woman (8.6% vs 13.5%; P<.001). The 5 provinces with the highest migrant inflow ratios were Guangdong, Shanghai, Beijing, Tianjin, and Zhejiang. Eastern coastal cities were the primary destination of MSM from southwestern China. Conclusions. Preferential MSM migration may influence MSM population sizes in both originating and destination provinces, particularly for provinces with uneven inflow and outflow. MSM migration from southwestern China, which has the highest HIV prevalence in this population, to coastal cities with lower prevalence may have implications for the spread of the HIV epidemic as well as HIV care services.

Because of the complexity of its sequelae, treatment strategies pose a challenge. Given this complexity, TBI provides a unique target of opportunity for complementary and alternative medicine (CAM) treatments. The present review describes and discusses current opportunitites and challenges associated with CAM research and clinical applications in civilian, veteran and military service populations. In addition to a brief overview of CAM, the translational capacity from basic to clinical research to clinical practice will be described. Finally, a systematic approach to developing an adoptable evidence base, with proof of effectiveness based on the literature will be discussed. Inherent in this discussion will be the methodological and ethical challenges associated with CAM research in those with TBI and associated comorbidities, specifically in terms of how these challenges relate to practice and policy issues, implementation and dissemination.

Aedes albopictus is a high priority for mosquito control efforts in the state. The efficacy of DeltaGard (R) (AI 2% deltamethrin) application against Ae. albopictus was evaluated in a residential area in St. Augustine, FL. DeltaGard was applied using a truck-mounted ultra-low-volume aerosol generator along 3 streets in a residential neighborhood. Caged mosquito mortality and droplet density data were recorded. Leaf clippings from houses on treated streets were bioassayed against laboratory-reared Ae. albopictus. Overall, the DeltaGard application was found to be more effective in the front yard of the houses, resulting in 78.3% mortality in caged mosquitoes, 42 % mortality in leaf bioassays, and 50.5 nl/cc in spray density. Based on the amount of vegetation and residential barriers around the houses, the application caused only 46.3% mortality in caged mosquitoes, 7.5% mortality in leaf bioassays, and 5.4 nl/cc in spray density in the back yard sites.

The ignited particles continued to burn in room temperature air. The air flow pattern was varied in different experiments to produce both laminar and turbulent flow conditions. The flow pattern was described using a computational fluid dynamics model; characteristics of the turbulent flow were established and correlated with the particle combustion characteristics. Particle burn times and temperatures were measured optically. Effect of turbulent flow conditions was observed on combustion characteristics for both aluminum and titanium powders. For both powders, luminous combustion streaks became shorter. For aluminum, the brightness of the streak and the optically measured temperature were also substantially reduced in the turbulent flow conditions. For titanium, reduction in both streak brightness and temperature were minor for different flow conditions. The burn rates of aluminum were observed to increase more than 4 times in the turbulent flows compared to the burn rates measured for the same powder in laminar flow. For titanium, the burn rates in turbulent flows were approximately twice as fast as in the laminar flow. Simple empirical correlations are proposed for both metals enabling one to predict the increase in the metal particle mass burn rate for turbulent flow conditions taking into account the particle size and such flow characteristics as Kolmogorov length scale and average kinetic energy.

The objectives of this study were to quantify effects of spinal orientation on lumbar spine injuries during single-cycle compressive loads and understand lumbar spine endplate injury tolerance. Twenty lumbar motion segments were compressed to failure. Two methods were used in the preparation of the lumbar motion segments. Group 1 (n=7) preparation maintained pre-test sagittal lordosis, whereas Group 2 (n=13) specimens had a free-rotational end condition for the cranial vertebra, allowing sagittal rotation of the cranial vertebra to create parallel endplates. Five Group 1 specimens experienced posterior vertebral body fracture prior to endplate fracture, whereas two sustained endplate fracture only. Group 2 specimens sustained isolated endplate fractures. Group 2 fractures occurred at approximately 41% of the axial force required for Group 1 fracture (p<0.05). Imaging and specimen dissection indicate endplate injury consistently took place within the confines of the endplate boundaries, away from the vertebral periphery. These findings indicate that spinal alignment during compressive loading influences the resulting injury pattern. This investigation identified the specific mechanical conditions under which an endplate breach will take place. Development of endplate injuries has significant clinical implication as previous research identified internal disc disruption (IDD) and degenerative disc disease (DDD) as long-term consequences of the axial load-shift that occurs following a breach of the endplate.

TI Anabolic hormone profiles in elite military men SO STEROIDS LA English DT Article DE Stress; Anabolic; Dehydroepiandrosterone; Testosterone; Military; Special operations ID SALIVARY TESTOSTERONE; DIURNAL PATTERNS; RESISTANCE EXERCISE; DEHYDROEPIANDROSTERONE-SULFATE; CORTISOL; STRESS; DHEA; ADOLESCENTS; DEPLOYMENT; PROTOCOLS AB We recently characterized the awakening responses and daily profiles of the catabolic stress hormone cortisol in elite military men. Anabolic hormones follow a similar daily pattern and may counteract the catabolic effects of cortisol. This companion report is the first to characterize daily profiles of anabolic hormones dehydroepiandrosterone (DHEA) and testosterone in this population. Overall, the men in this study displayed anabolic hormone profiles comparable to that of healthy, athletic populations. Consistent with the cortisol findings in our prior report, summary parameters of magnitude (hormone output) within the first hour after awakening displayed superior stability versus summary parameters of pattern for both DHEA (r range: 0.77-0.82) and testosterone (r range: 0.62-0.69). Summary parameters of evening function were stable for the two hormones (both p < 0.001), while the absolute decrease in testosterone across the day was a stable proxy of diurnal function (p < 0.001). Removal of noncompliant subjects did not appreciably affect concentration estimates for either hormone at any time point, nor did it alter the repeatability of any summary parameter. The first of its kind, this report enables accurate estimations of anabolic balance and resultant effects upon health and human performance in this highly resilient yet chronically stressed population.

TI Incidence, Etiology and Risk Factors for Travelers' Diarrhea during a Hospital Ship-Based Military Humanitarian Mission: Continuing Promise 2011 SO PLOS ONE LA English DT Article ID UNITED-STATES-NAVY; US MILITARY; CRUISE SHIP; PERSONNEL; DISEASE; DEPLOYMENT; IDENTIFICATION; PREVENTION; INFECTION; OUTBREAKS AB Travelers' diarrhea (TD) is the most common ailment affecting travelers, including deployed U.S. military. Continuing Promise 2011 was a 5-month humanitarian assistance/disaster response (HA/DR) military and non-governmental organization training mission aboard the hospital ship USNS Comfort, which deployed to Central and South America and the Caribbean between April and September 2011. Enhanced TD surveillance was undertaken during this mission for public health purposes. Passive surveillance (clinic visits), active surveillance (self-reported questionnaires), and stool samples were collected weekly from shipboard personnel. Descriptive statistics and multivariate-logistic regression methods were used to estimate disease burden and risk factor identification. Two polymerase chain reaction methods on frozen stool were used for microbiological identification. TD was the primary complaint for all clinic visits (20%) and the leading cause of lost duties days due to bed rest confinement (62%), though underreported, as the active self-reported incidence was 3.5 times higher than the passive clinic-reported incidence. Vomiting (p = 0.002), feeling lightheaded or weak (p = 0.005), and being a food handler (p = 0.017) were associated with increased odds of lost duty days. Thirty-eight percent of self-reported cases reported some amount of performance impact. Based on the epidemiological curve, country of exercise and liberty appeared to be temporally associated with increased risk. From the weekly self-reported questionnaire risk factor analysis, eating off ship in the prior week was strongly associated (adjusted odds ratio [OR] 2.4, p<0.001). Consumption of seafood increased risk (aOR 1.7, p = 0.03), though consumption of ice appeared protective (aOR 0.3, p = 0.01). Etiology was bacterial (48%), with enterotoxigenic Escherichia coli as the predominant pathogen (35%). Norovirus was identified as a sole pathogen in 12%, though found as a copathogen in an additional 6%. Despite employment of current and targeted preventive interventions, ship-board HA/DR missions may experience a significant risk for TD among deployed US military personnel and potentially impact mission success.

TI A compressible two-phase model for dispersed particle flows with application from dense to dilute regimes SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID TO-DETONATION TRANSITION; GRANULAR-MATERIALS; SOLID PARTICLES; MIXTURES; INTERFACES; SHOCKS; WAVES; FIELD AB Multiphase flows are present in many important fields ranging from multiphase explosions to chemical processing. An important subset of multiphase flow applications involves dispersed materials, such as particles, droplets, and bubbles. This work presents an Eulerian-Eulerian model for multiphase flows containing dispersed particles surrounded by a continuous media such as air or water. Following a large body of multiphase literature, the driving force for particle acceleration is modeled as a direct function of both the continuous-phase pressure gradient and the gradient of intergranular stress existing within the particle phase. While the application of these two components of driving force is well accepted in much of the literature, other models exist in which the particle-phase pressure gradient itself drives particle motion. The multiphase model treats all phases as compressible and is derived to ensure adherence to the 2nd Law of Thermodynamics. The governing equations are presented and discussed, and a characteristic analysis shows the model to be hyperbolic, with a degeneracy in the case that the intergranular stress, which is modeled as a configuration pressure, is zero. Finally, results from a two sample problems involving shock-induced particle dispersion are presented. The results agree well with experimental measurements, providing initial confidence in the proposed model. Published by AIP Publishing.

The crystalline compounds have been characterized by single-crystal X-ray diffraction, electrochemical experiments, EPR, magnetic susceptibility, and density functional theory (DFT) studies. The collective data show that 1 and 2 contain Al3+ metal centers coordinated by three bipyridine (bpy(center dot))(1) monoanion radicals. Electrochemical studies show that six redox states are accessible from the neutral complexes, three oxidative and three reductive, that involve oxidation or reduction of the coordinated bpy ligands to give neutral (R)bpy or (R)bpy(2) dianions, respectively. Magnetic susceptibility measurements (4-300 K) coupled with DFT studies show strong antiferromagnetic coupling of the three unpaired electrons located on the Rbpy ligands to give S = 1/2 ground states with low lying S = 3/2 excited states that are populated above 110 K (1) and 80 K (2) in the solid-state. Complex 2 shows weak 3D magnetic interactions at 19 K, which is not observed in 1 or the related [Al(bpy)3] complex.

TI A comparison of compliance rates with anti-vectorial protective measures during travel to regions with dengue or chikungunya activity, and regions endemic for Plasmodium falciparum malaria SO JOURNAL OF TRAVEL MEDICINE LA English DT Article DE Anti-vectorial protective measures; malaria; dengue; chikungunya; compliance ID PERSONAL PROTECTION; KNOWLEDGE; ATTITUDES; OUTBREAK; MISSIONS; VIRUS; RISK; IRAQ AB Background. There is limited information on compliance rates with anti-vectorial protective measures (AVPMs) during travel to countries with risk of dengue and chikungunya. We evaluated differences in mosquito exposures, and factors associated with AVPM compliance in travellers going to countries where the principal mosquito- borne infectious disease threat is falciparum malaria and those where risk of dengue or chikungunya predominates. Methods. Department of Defence beneficiaries with planned travel to regions where the predominant mosquito-borne infection is falciparum malaria, and those with predominantly dengue or chikungunya risk, were included. Regions were divided into three groups: 'high-risk falciparum malaria', 'low-risk falciparum malaria' and 'chikungunya/dengue risk'. Demographics, trip characteristics, arthropod exposure and AVPM compliance were captured using pre- and post-travel surveys. Skin repellent compliance was defined as self-reported use, categorized as 'often/every day'. A logistic regression model was used to estimate factors associated with AVPM compliance. Results. 183 (9%), 185 (9%) and 149 (7%) travelled to high and low falciparum malaria risk regions, and chikungunya/dengue risk regions, respectively. Overall, 53% (95% CI: 48-57%) and 16% (95% CI: 12-19%) were compliant with repellent use on skin and clothing, respectively. Daytime bites were reported more frequently in chikungunya/dengue risk regions than high malaria risk regions (37% vs. 10%), while night time bites were frequently in high malaria risk regions (53% vs 20%; P < 0.001). Compliance with skin repellents was associated with female gender [RR: 1.54 (95% CI: 1.05-2.28)], observing mosquitoes during travel [RR: 2.77 (95% CI: 1.76-4.36)] and travel during the rainy season [RR: 2.45 (95% CI: 1.66-3.71)]). Conclusions. Poor AVPM compliance was observed in the overall cohort. Compliance with skin repellent use was associated with female gender, observing mosquitoes and travelling during the rainy season, and was not associated with the risk of malaria or chikungunya/dengue at the travel destination.

TI Sleep and Health Resilience Metrics in a Large Military Cohort SO SLEEP LA English DT Article DE cohort; military; resilience; sleep ID MILLENNIUM COHORT; US MILITARY; MENTAL-HEALTH; CARE UTILIZATION; RISK-FACTORS; PRIME-MD; DEPRIVATION; PREVALENCE; DEPLOYMENT; PERSONNEL AB Study Objectives: Examine the relationship between self-reported sleep parameters and indicators of resilience in a US military population (n = 55,021). Methods: Longitudinal analyses (2001-2008) were conducted using subjective data collected from Millennium Cohort Study questionnaires and objective data from military records that included demographics, military health, and deployment information. Subjective sleep duration and insomnia symptoms were collected on the study questionnaire. Resilience metrics included lost work days, self-rated health, deployment, frequency and duration of health care utilization, and early discharge from the military. Generalized estimating equations and survival analyses were adjusted for demographic, military, behavioral, and health covariates in all models. Results: The presence of insomnia symptoms was significantly associated with lower self-rated health, more lost work days, lower odds of deployment, higher odds of early discharge from military service early, and more health care utilization. Those self-reporting < 6 h (short sleepers) or > 8 h (long sleepers) of sleep per night had similar findings, except for the deployment outcome in which those with the shortest sleep were more likely to deploy. Conclusions: Poor sleep is a detriment to service members' health and readiness. Leadership should redouble efforts to emphasize the importance of healthy sleep among military service members, and future research should focus on the efficacy of interventions to promote healthy sleep and resilience in this population.

The EHD body force model is based on solving the electrostatic equations for electric potential and net charge density. The boundary condition for net charge density on the dielectric surface is obtained from a space-time lumped-element (STLE) circuit model or an empirical model. The DBD-URANS/LES coupled solver has been implemented using a multiple-domain approach and a multiple subcycle technique. The DBD plasma-induced flow in a quiescent environment is used to validate the coupled solver, evaluate different EHD body force models, and compare the performance of the actuator driven by voltage with various waveforms and amplitudes.

TI Surveillance for severe acute respiratory infections in Southern Arizona, 2010-2014 SO INFLUENZA AND OTHER RESPIRATORY VIRUSES LA English DT Article DE Arizona; influenza; respiratory tract diseases; surveillance ID INFLUENZA; VIRUSES; IDENTIFICATION; CHILDREN; STATES AB BackgroundThe Binational Border Infectious Disease Surveillance program began surveillance for severe acute respiratory infections (SARI) on the US-Mexico border in 2009. Here, we describe patients in Southern Arizona. MethodsPatients admitted to five acute care hospitals that met the SARI case definition (temperature 378 degrees C or reported fever or chills with history of cough, sore throat, or shortness of breath in a hospitalized person) were enrolled. Staff completed a standard form and collected a nasopharyngeal swab which was tested for selected respiratory viruses by reverse transcription polymerase chain reaction. ResultsFrom October 2010-September 2014, we enrolled 332 SARI patients. Fifty-two percent were male and 48% were white non-Hispanic. The median age was 63 years (47% 65 years and 52% <5 years). During hospitalization, 51 of 230 (22%) patients required intubation, 120 of 297 (40%) were admitted to intensive care unit, and 28 of 278 (10%) died. Influenza vaccination was 56%. Of 309 cases tested, 49 (16%) were positive for influenza viruses, 25 (81%) for human metapneumovirus, 20 (65%) for parainfluenza viruses, 16 (52%) for coronavirus, 11 (36%) for respiratory syncytial virus, 10 (32%) for rhinovirus, 4 (13%) for rhinovirus/enterovirus, 3 (10%) for enteroviruses, and 3 (10%) for adenovirus. Among the 49 influenza-positive specimens, 76% were influenza A (19 H3N2, 17 H1N1pdm09, and 1 not subtyped), and 24% were influenza B. ConclusionInfluenza viruses were a frequent cause of SARI in hospitalized patients in Southern Arizona. Monitoring respiratory illness in border populations will help better understand the etiologies. Improving influenza vaccination coverage may help prevent some SARI cases.

TI Sexual Trauma and Adverse Health and Occupational Outcomes Among Men Serving in the US Military SO JOURNAL OF TRAUMATIC STRESS LA English DT Article ID ASSAULT HISTORY; MILLENNIUM COHORT; GENERAL-POPULATION; VETERANS; AFGHANISTAN; INSTRUMENTS; HARASSMENT; WOMEN; PTSD; IRAQ AB Although absolute counts of U.S. service men who experience sexual trauma are comparable to service women, little is known about the impact of sexual trauma on men. The association of recent sexual trauma (last 3 years) with health and occupational outcomes was investigated using longitudinal data (2004-2013) from the Millennium Cohort Study. Of 37,711 service men, 391 (1.0%) reported recent sexual harassment and 76 (0.2%) sexual assault. In multivariable models, sexual harassment or assault, respectively, was associated with poorer mental health: AOR = 1.60, 95% CI [1.22, 2.12], AOR = 4.39, 95% CI [2.40, 8.05]; posttraumatic stress disorder: AOR = 2.50, 95% CI [1.87, 3.33], AOR = 6.63, 95% CI [3.65, 12.06]; depression: AOR = 2.37, 95% CI [1.69, 3.33], AOR = 5.60, 95% CI [2.83, 11.09]; and multiple physical symptoms: AOR = 2.22, 95% CI [1.69, 2.92]; AOR = 3.57, 95% CI [1.98, 6.42], after adjustment for relevant covariates. Sexual harassment was also associated with poorer physical health: AOR = 1.68, 95% CI [1.27, 2.22]. Men who reported sexual trauma were more likely to have left military service: AOR = 1.60, 95% CI [1.14, 2.24], and be disabled/unemployed postservice: AOR = 1.76, 95% CI [1.02, 3.02]. Results suggest that sexual trauma was significantly associated with adverse health and functionality extending to postmilitary life. Findings support the need for developing better prevention strategies and services to reduce the burden of sexual trauma on service men.

TI Treatment of Mental or Physical Health Problems in a Combat Zone: Comparisons of Postdeployment Mental Health and Early Separation From Service SO JOURNAL OF TRAUMATIC STRESS LA English DT Article ID MILITARY PERSONNEL; US MILITARY; PSYCHIATRIC DIAGNOSES; TRAUMA REGISTRY; IRAQ; THEATER; DEPLOYMENT; DISORDERS; ADHERENCE; VETERANS AB The primary aim of this study was to evaluate whether being treated for mental health or nonbattle physical injury during military combat deployment was associated with higher risk for postdeployment mental disorders and poorer career outcomes than seen in the general combat-deployed population. Service members treated in theater for mental health (n = 964) or noncombat injury (n = 853) were compared with randomly sampled personnel (n = 7,220) from the general deployed population on diagnosed mental disorders and early separation from service. Deployment, medical, and career information were obtained from Department of Defense archival databases. Over half of the personnel who received mental health treatment while deployed were diagnosed with 1 or more mental disorders postdeployment and/or were separated from service before completing their full-term enlistment. This was significantly higher than expected compared to the general deployed group, adjusting for demographic/military characteristics and mental health history (adjusted odds ratios [ORs] ranging 1.62 to 2.96). Frequencies of problems also were higher in the mental health-treated group than in the group treated for nonbattle physical injuries (significant adjusted ORs ranging 1.65 to 2.58). The documented higher risks for postdeployment adjustment problems suggested that especially those treated in theater by mental health providers might benefit from postdeployment risk-reduction programs.

TI Exercise training with blood flow restriction has little effect on muscular strength and does not change IGF-1 in fit military warfighters SO GROWTH HORMONE & IGF RESEARCH LA English DT Article DE Blood flow restriction; Exercise; Insulin-like growth factor-1; IGF axis; Warfighters ID INTENSITY RESISTANCE EXERCISE; GROWTH-FACTOR-I; VASCULAR OCCLUSION; BINDING PROTEIN-3; MUSCLE; HORMONE; INSULIN; THRESHOLD; RESPONSES; IGFBP-3 AB Objective: Aerobic exercise with blood flow restriction (aBFR) has been proposed as an adjunctive modality in numerous populations, potentially via an enhanced growth factor response. However, the effects of aBFR on highly trained warfighters have yet to be examined. The purpose of this study was to determine if adjunctive aBFR as part of a regular physical training regimen would increase markers of aerobic fitness and muscle strength in elite warfighters. In addition, we sought to determine whether the changes in blood lactate concentration induced by aBFR would be associated with alterations in the insulin-like growth factor (IGF) axis. Design: Active-duty US Naval Special Warfare Operators (n = 18, age = 36.8 +/- 2.2 years, weight = 89.1 +/- 1.2 kg, height = 181.5 +/- 1.4 cm) from Naval Amphibious Base Coronado were recruited to participate in 20 days of adjunctive aBFR training. Peak oxygen consumption (VO2 peak), ventilatory threshold (VT), and 1-repetition max (1-RM) bench press and squat were assessed pre- and post-aBFR training. Blood lactate and plasma IGF-1 and IGF-binding protein-3 (IGFBP-3) were assessed pre-, 2 min post-, and 30 min post-aBFR on days 1, 9, and 20 of aBFR training. Results: Following aBFR training there were no changes in VO2 peak or VT, but there was an increase in the 1-RM for the bench press and the squat (5.0 and 3.9%, respectively, P < 0.05). Blood lactate concentration at the 2-min post-exercise time point was 4.5-7.2-fold higher than pre-exercise levels on all days (P < 0.001). At the 30-min post-exercise time point, blood lactate was still 1.6-2.6-fold higher than pre-exercise levels (P < 0.001), but had decreased by 49-56% from the 2-min post-exercise time point (P < 0.001). Plasma IGF-1 concentrations did not change over the course of the study. On day 9, plasma IGFBP-3 concentration was 4-22% lower than on day 1 (P < 0.01) and 22% lower on day 9 than on day 20 at the 30-min post-exercise time point (P < 0.001). Conclusions: Our data suggest that aBFR training does not lead to practical strength adaptations or alterations in the IGF axis in a population of highly trained warfighters.

Due to the novelty of this rapidly developing technology, a very limited, yet swiftly evolving literature exists on the topic. Motivated by these two points, we have attempted to catalog and analyze the published fatigue performance data of an additively manufactured alloy of significant technological interest, Ti-6Al-4V. Focusing on uniaxial fatigue performance, we compare to traditionally manufactured Ti-6Al-4V, discussing failure mechanisms, defects, microstructure, and processing parameters. We then attempt to identify key knowledge gaps that must be addressed before AM technology can safely and effectively be employed in critical load bearing applications. (C) 2015 Elsevier Ltd.

The method leverages FDM's ability to fabricate spatially varying 3D structures with variable polymer fill volumes, thus producing a spatially varying effective permittivity profile. The method is validated experimentally within the Ka-band. Experimental results closely match predictions, and AR treated samples demonstrate much less transmission loss than non-AR treated samples.

Evaluations were conducted with 7 machine chemical combinations, 3 depths of spray, and 3 species of laboratory-reared mosquitoes, Anopheles quadrimaculatus, Culex quinquefasciatus, and Aedes aegypti. Combinations of these factors were analyzed in conjunction with environmental parameters. Data showed statistical significance between all machines. The Bonide machine maintained integrity and durability for the longest period of time compared with the other 2 machines. When evaluating the 3 machines with DUET (TM), mortality was highest with the Bonide and lowest with the Burgess machine.

AM has already been implemented in naval facilities with notable successes in the areas of rapid fabrication, legacy part development and repair, custom, tooling, rapid prototyping, and novel designs. Though AM has afforded many positive successes in naval applications, additional technology development in areas such as the production of quality metal parts and rapid qualification are needed to fully capture the manufacturing advantages to the warfighter that AM offers.

TI A Hybrid Agent Type-1 Fuzzy Logic System for Set-Based Conceptual Ship Design Communications and Negotiations SO NAVAL ENGINEERS JOURNAL LA English DT Article ID ENGINEERING DESIGN; OPTIMIZATION AB A methodology for the implementation of set-based design communications and negotiations in the conceptual ship design phase is outlined. The newly developed methodology relies on a hybrid agent type-1 fuzzy logic system (FLS). The hybridization stems from the use of human designers who fulfill agent roles by interacting with a computational fuzzy logic system, graphical user interfaces, and a networked software tool. The authors outline the motivation for the development of the hybrid agent set based type-1 FLS, including the differences and benefits between point-based and set-based design methods. Details of the hybrid agent FLS components, as well as the communications and negotiations process, are also discussed. Conceptual container ship designs were performed in order to verify the functionality of the method and associated tools. The results show the ability of the hybrid agent type-1 FLS to facilitate the core set-based design values of set-based communication and gradual narrowing of the solution space. The FLS method was also compared to an unstructured chat window, Internet based, communications method commonly used by design groups working from multiple locations. A comparison of the two methods showed the structured FLS to be more capable of facilitating SBD qualities than the chat window method.

The sensor is fabricated using a femto-second (fs) laser. The fs-laser-based fabrication makes the sensor thermally stable to sustain operating temperatures as high as 800 degrees C. The sensor has low sensitivity toward the temperature as compared to its response toward the applied strain. The performance of the EFPI sensor is tested in an embedded application. The host material is carbon fiber/bismaleimide (BMI) composite laminate that offer thermally stable characteristics at high ambient temperatures. The sensor exhibits highly linear response toward the temperature and strain. Analytical work done with embedded optical-fiber sensors using the out-of-autoclave BMI laminate was limited until now. The work presented in this paper offers an insight into the strain and temperature interactions of the embedded sensors with the BMI composites.

Preparing for combat readiness for the fight: physical performance profile of female US Marines. J Strength Cond Res 30(3): 595-604, 2016Females have been restricted from serving in direct combat arms' positions for decades. One reason for the exclusion derives from the perceived physical demands of these positions. As a result, many current efforts are directed toward defining the physical demands of combat arms' positions. The purpose of this study was to develop a physical performance and body composition profile of females who could overcome the physical demands of combat tasks that rely primarily on upper body strength. This study is based on an analysis of archival data from 2 separate samples of active-duty female Marines (n = 802), who had been recruited to participate in heavy lifting tasks. These tasks included lifting a heavy machine gun (HMG) lift (cohort 1, n = 423) and Clean and Press lifts (29.5-52.3 kg) (cohort 2, n = 379). To develop the physical performance profile, data from annual physical fitness tests were collected, which included run times, ammunition can lift, 804. Seven-meter (880-yard) movement to contact, and the maneuver under fire. In cohort 1, 65 females (approximate to 15%; n = 423 females) successfully completed HMG; in cohort 2, 33 females (approximate to 9%; n = 379 females) successfully completed another strength task, a Clean and Press of 52.3 kg. In both samples, female Marines who were successful on these tasks also outperformed their unsuccessful counterparts on the annual physical fitness tests. In addition, larger females typically outperformed their smaller counterparts. Females seeking assignment to closed combat arms' positions would thus be well served by targeting upper body strength, while maintaining overall physical fitness.

In this paper, the design of a volume-phase holographic grating, simultaneously optimized to operate in the red, green, and blue wavelengths, is presented along with a study of its fabrication tolerances. The grating is optimized to produce 98% efficiency at lambda = 532 nm and at least 75% efficiency in the region between 400 and 700 nm, when the incident light is unpolarized. The optimization is done for recording in dichromated gelatin with a thickness of 12 mu m, an average refractive index of 1.5, and a refractive index modulation of 0.022.

Static pressure, unsteady surface pressure, and velocity measurements were made throughout the trailing-edge region of an airfoil model with three interchangeable, symmetric trailing-edge sections. The data of the present study were used to develop a new model for estimation of fluctuating surface pressure autospectra beneath two-dimensional turbulent boundary layer flow experiencing an adverse pressure gradient of variable strength. This new model has been used to compare with data from six separate experimental investigations from literature, and has been compared against a separately developed empirical model of the fluctuating surface pressure. Additional empirical modeling of the coherent extents of the fluctuating pressure field in the longitudinal and lateral directions, as well as the convection velocity, is presented as a function of nondimensional variables dependent on the adverse pressure gradient flow condition.

This study examined longitudinal trends in MPS status and its relationship to deployment in U.S. military service members. Methods: Using longitudinal data from panel 1 participants in the Millennium Cohort Study (n = 76,924), MPS status was assessed at three time points (2001-2008) using the 15 -item Patient Health Questionnaire. Probability of reporting MPS was analyzed using mixed-effects multinomial logit regression, with time and deployment experience as main explanatory variables. Results: After adjustment for demographic, military, and health characteristics, service members who deployed with combat were significantly more likely to report MPS at each time point compared with those not deployed (odds ratio [OR] and 95% confidence interval [CI] for wave 1 =1.49 [1.47-1.52], wave 2 = 1.73 [1.69-1.78], wave 3 = 2.08 [2.03-2.12]), and those who deployed without combat (OR and CI for wave 1 = 2.66 [2.59-2.74], wave 2 = 1.81 [1.75-1.87]; wave 3 = 1.68 [1.63-1.74]). Conclusions: Longitudinal trends indicate that the probability of reporting MPS has increased consistently over time only for those deployed, regardless of combat experience. (C) 2016 Elsevier Inc.

TI Small-Scale Safety Testing of Ammonium Nitrate and Mixtures SO PROPELLANTS EXPLOSIVES PYROTECHNICS LA English DT Article DE Safety testing; Ammonium nitrate; Gunpowder; Impact sensitivity; Ammonium nitrate mixtures AB Ammonium nitrate (AN), gunpowder (GP), and an ammonium nitrate gunpowder mixture (AN/GP) were studied for impact sensitivity by four laboratories using the drop hammer apparatus. Bruceton and Neyer methods were used as experimental protocols and for data reduction. The results are presented as 50% probability of reaction (DH50). For AN, the DH50 values are widely varied among the participants, from sensitive to completely insensitive (limit of the equipment), with no real correlation among results. GP and the AN/GP mixture exhibited much more sensitivity overall and were in some cases within statistical values extrapolated from previous studies of RDX. The variability in results for the AN data is attributed to the difficulty in determining a positive reaction event for AN, as detailed by Neyer experiments and photography during positive reactions. Variability in results for the GP and AN/GP mixtures is attributed to equipment environment and detection criteria. This work was performed by the Integrated Data Collection Analysis (IDCA) program, a multi-laboratory effort to standardize safety testing of improvised or homemade explosives funded by the Department of Homeland Security.

TI Small-Scale Thermal Studies of Volatile Homemade Explosives SO PROPELLANTS EXPLOSIVES PYROTECHNICS LA English DT Article DE Small-scale safety testing; Thermal screening; Differential scanning calorimetry; Homemade explosives; HME; Round-robin test; Proficiency test ID AMMONIUM-NITRATE; POTASSIUM PERCHLORATE; STABILITY; DSC AB Several homemade or improvised explosive mixtures that either contained volatile components or produced volatile products were examined using standard small-scale safety and thermal (SSST) testing that employed differential scanning calorimetry (DSC) techniques (constant heating rate and standard sample holders). KClO3 and KClO4 mixtures with dodecane exhibited different enthalpy behavior when using a vented sample holder in contrast to a sealed sample holder. The standard configuration produced profiles that exhibited only endothermic transitions. The sealed system produced profiles that exhibited additional exothermic transitions absent in the standard configuration produced profiles. When H2O2/fuel mixtures were examined, the volatilization of the peroxide (endothermic) dominated the profiles. When a sealed sample holder was used, the energetic releases of the mixture could be clearly observed. For AN and AN mixtures, the high temperature decomposition appears as an intense endothermic event. Using a nominally sealed sample holder also did not adequately contain the system. Only when a high-pressure rated sample holder was used the high temperature decomposition of the AN could be detected as an exothermic release. The testing was conducted during a proficiency (or round-robin type) test that included three U.S. Department of Energy and two U.S. Department of Defense laboratories. In the course of this proficiency test, certain HMEs exhibited thermal behavior that was not adequately accounted for by standard techniques. Further examination of this atypical behavior highlighted issues that may have not been recognized previously because some of these materials are not routinely tested. More importantly, if not recognized, the SSST testing results could lead to inaccurate safety assessments. This study provides examples, where standard techniques can be applied, and results can be obtained, but these results may be misleading in establishing thermal properties.

TI High dynamic range thermometry at 5kHz in hydrogen-air diffusion flame using chirped-probe-pulse femtosecond coherent anti-stokes Raman scattering SO JOURNAL OF RAMAN SPECTROSCOPY LA English DT Article DE CARS; ultrafast; combustion diagnostics ID SPECTROSCOPY AB Chirped probe pulse femtosecond coherent anti-Stokes Raman scattering (CPP fs-CARS) thermometry was performed at 5kHz in a hydrogen jet diffusion flame with an air co-flow. Measurements were performed at different heights and radial locations within the jet diffusion flame, up to 16 nozzle exit diameters downstream (x/d=16). The near-nozzle measurements were characterized by large, organized, buoyancy-driven instabilities that become more chaotic at the downstream locations x/d4. The diffusion flame results highlight temperature fluctuations characteristic of the buoyancy-driven Kelvin-Helmholtz-type instability and provide new insights into the transient structure of these flames. At some measurement locations, the time-varying temperatures ranged from 300K to nearly 2400K. The CPP fs-CARS signal intensity is a factor of approximately 1000 times lower at 2400K compared with 300K. A dual-channel detection system was used to increase the dynamic range of the CARS measurements. The determination of temperature from the single shot spectra is discussed in detail. Laser and detection system parameters were determined from CPP fs-CARS spectra obtained from a near-adiabatic laminar calibration flame apparatus. The temperature precision of the system was determined from these calibration measurements and was found to be better than 2.0% at 2200K. The influence of an instrument response function on spectral fitting parameters is systematically assessed. Published 2015.

TI Survey of Detection, Mitigation, and Repair Technologies to Address Problems Caused by Sensitization of Al-Mg Alloys on Navy Ships SO CORROSION LA English DT Article DE aluminum alloy; marine environments; sensitization; stress corrosion cracking ID ULTRASONIC IMPACT TREATMENT; STRESS-CORROSION CRACKING; BETA-PHASE PRECIPITATION; ALUMINUM-ALLOY; INTERGRANULAR CORROSION; BEHAVIOR; FATIGUE; DELAMINATION; ORIENTATION; MECHANISM AB Structural aluminum alloys are used in marine applications where light weight and increased speed are paramount. The 5xxx series alloys are the ideal choice, providing an optimum combination of as-welded strength and general corrosion resistance. A particular concern is sensitization in service. Aluminum is considered sensitized when a nearly continuous network of beta phase forms along the grain boundaries. The beta phase is anodic to the Al matrix, and, when exposed to sea water and sufficient loading, provides a clear pathway to stress corrosion cracking (SCC). The degree of beta-phase precipitation is driven by a combination of time and elevated temperature. For over a decade, SCC of Al superstructures has plagued Navy ships. To address this issue, relevant technologies have been adopted, adapted, and developed to combat this issue. More specifically, the technology areas involve the detection of sensitization, the mitigation of SCC, and the replacement of corrupt materials. The technologies discussed herein are all currently used on the waterfront, and their use is summarized in a case study at the end of this survey. C1 [Golumbfskie, W. J.; Tran, K. T.; Noland, J.

TI X-ray photoelectron spectroscopy of select multi-layered transition metal carbides (MXenes) SO APPLIED SURFACE SCIENCE LA English DT Article DE MXene; XPS; Metal carbides ID 2-DIMENSIONAL TITANIUM CARBIDE; HIGH VOLUMETRIC CAPACITANCE; THIN-FILMS; ELECTRONIC-PROPERTIES; MOLYBDENUM-DISULFIDE; THERMAL-STABILITY; GRAPHITE OXIDE; ION BATTERIES; ATOMIC LAYERS; XPS ANALYSIS AB In this work, a detailed high resolution X-ray photoelectron spectroscopy (XPS) analysis is presented for select MXenes a recently discovered family of two-dimensional (2D) carbides and carbonitrides. Given their 2D nature, understanding their surface chemistry is paramount. Herein we identify and quantify the surface groups present before, and after, sputter-cleaning as well as freshly prepared vs. aged multi layered cold pressed discs. The nominal compositions of the MXenes studied here are Ti-3 C2Tx,Ti3CNTx, Nb2CTx and Nb4C3Tx where T represents surface groups that this work attempts to quantify. In all the cases, the presence of three surface terminations, O, OH and F, in addition to OH-terminations relatively strongly bonded to H2O molecules, was confirmed. From XPS peak fits, it was possible to establish the average sum of the negative charges of the terminations for the aforementioned MXenes. Based on this work, it is now possible to quantify the nature of the surface terminations. This information can, in turn, be used to better design and tailor these novel 2D materials for various applications. Published by Elsevier B.V.

TI A temperature-mapping molecular sensor for polyurethane-based elastomers SO APPLIED PHYSICS LETTERS LA English DT Article ID VISIBLE-LIGHT; EXPLOSIVES; DESIGN AB We present a crosslinked polyurethane elastomer featuring a thermochromic molecular sensor for local temperature analysis. The thermochrome is a modified donor-acceptor Stenhouse adduct (DASA) that was dispersed homogeneously into the polymer blend in minuscule amounts. Rapid temperature jump measurements in a pyroprobe and impacts in a Hopkinson bar show that the DASA has suitable kinetics for detecting localized temperature increase following impact or rapid heating. The thermochrome retains a signature of the peak temperature in the elastomer, allowing post-mortem mapping of micron-scale temperature localization in materials such as explosive and propellant composites. We demonstrate the concept by using the kinetics of the DASA activation to determine peak temperatures reached during bullet perforation of the polyurethane. (C) 2016 AIP Publishing LLC.

TI Development of the Flu-PRO: a patient-reported outcome (PRO) instrument to evaluate symptoms of influenza SO BMC INFECTIOUS DISEASES LA English DT Article DE Influenza; Symptoms; Patient-reported outcomes; Endpoints; Outcome assessments; Content validity ID TASK-FORCE REPORT; CONTENT VALIDITY AB Background: To develop content validity of a comprehensive patient-reported outcome (PRO) measure following current best scientific methodology to standardize assessment of influenza (flu) symptoms in clinical research. Methods: Stage I (Concept Elicitation): 1:1 telephone interviews with influenza-positive adults (>= 18 years) in the US and Mexico within 7 days of diagnosis. Participants described symptom type, character, severity, and duration. Content analysis identified themes and developed the draft Flu-PRO instrument. Stage II (Cognitive Interviewing): The Flu-PRO was administered to a unique set of influenza-positive adults within 14 days of diagnosis; telephone interviews addressed completeness, respondent interpretation of items and ease of use. Results: Samples: Stage I: N = 46 adults (16 US, 30 Mexico); mean (SD) age: 38 (19), 39 (14) years; % female: 56 %, 73 %; race: 69 % White, 97 % Mestizo. Stage II: N = 34 adults (12 US, 22 Mexico); age: 37 (14), 39 (11) years; % female: 50 %, 50 %; race: 58 % White, 100 % Mestizo. Symptoms: Symptoms identified by >50 %: coughing, weak or tired, throat symptoms, congestion, headache, weakness, sweating, chills, general discomfort, runny nose, chest (trouble breathing), difficulty sleeping, and body aches or pains. No new content was uncovered during Stage II; participants easily understood the instrument. Conclusions: Results show the 37-item Flu-PRO is a content valid measure of influenza symptoms in adults with a confirmed diagnosis of influenza. Research is underway to evaluate the suitability of the instrument for children and adolescents. This work can form the basis for future quantitative tests of reliability, validity, and responsiveness to evaluate the measurement properties of Flu-PRO for use in clinical trials and epidemiology studies.

However, the high energy manufacturers continue to rely on traditional chemicals to meet their needs. New energetic materials must be developed to extend their capabilities and handling capabilities. The new materials which have been prepared recently have led to new possibilities. Important advances have been made especially in the area of high-nitrogen compounds, organic difluoramine derivatives. Computational simulations have also led not only to a greater insight into the basic thermodynamics and kinetics of these materials but also their practical behavior in the field. This chapter summarizes new developments that have been achieved since Volume 126 of Structure and Bonding, which was published in 2007 and gave a comprehensive review of the field.

The XPS spectra were collected using conventional Mg X-rays with energy of 1253.6 eV as well as synchrotron X-rays with energies of 2493.6 and 3498.4 eV in order to examine the depth distribution of various surface chemical species induced during cycling. The XPS spectra revealed a 5 - 10 nm surface layer of organic and LixPFyOz-type species formed as result of electrolyte decomposition, and a comparatively thinner layer composed of transition metal fluorides and LiF. These results suggest that electrolyte decomposition is a major contributor to parasitic reactions in LNMO battery electrochemistry. Limiting electrolyte decomposition with the use of solvents with wide electrochemical stability windows thus comprises a promising strategy for ensuring the practical feasibility of high voltage spinel materials in future Li-ion systems.

Although many experimental and numerical investigations have indicated that the spanwise-oriented DBD plasma actuator is an effective flow control method, the application is difficult to extend from model-scale to full-scale problems, partly due to the required high amplitude and high bandwidth excitation. Also, the flow control mechanism associated with a spanwise-oriented DBD actuator is mainly direct momentum injection, therefore, the effectiveness of actuation is sensitive to the location of the DBD actuator relative to the location of flow separation. On the other hand, a few experimental studies have shown promising results using the DBD Vortex Generator (DBD-VG) consisting of multiple plasma DBD actuators oriented in the streamwise direction. By generating streamwise vortices extending a long distance downstream, the DBD-VGs enhance the mixing of the inner and outer layers of turbulent boundary layer flows. As a result, the boundary layer can better withstand an adverse pressure gradient. When applied to flow separation control, the effectiveness of the DBD-VGs should be less sensitive to location of flow separation. The present work extends the capability of the integrated numerical simulation tool from a single spanwise-oriented DBD plasma actuator to multiple DBD plasma actuators oriented in any direction, including the streamwise direction. As a demonstration of the new capability in the DBD-URANS coupled solver, numerical simulations of flow induced by a DBD-VG actuator with an array of exposed electrodes in a quiescent environment, as well as in a turbulent boundary layer over a flat plate, are carried out. The numerical simulation successfully reproduced the longitudinal vortices embedded in the boundary layer.

The rough wall model is implemented as a wall function and is used in conjunction with the k-omega turbulence model. The roughness model is validated against experiments conducted on rough plates in a water tunnel and towed in a channel. Two sets of simulations, single-phase Reynolds-Averaged Navier-Stokes (RANS) and two-phase unsteady RANS were conducted to validate the current roughness model. Current results show good agreement with the roughness functions (Delta U+) and is within 1.5% of the experimental results. The overall frictional resistance predicted for the rough plates towed in a water channel is within 2% of the experimentally obtained results. With these promising results, the aim is to develop a computational capability for predicting added hull resistance due to biofouling.

The forecasted ship motion is particularly useful in sea states above SS3 when unanticipated large motions can suddenly occur. A 5- to 10-second forecast of future ship motion provides the operator time to compensate for the motion to avoid serious collisions. Ship motion forecasting can enable autonomous landing during higher sea states and can also provide an alternative ship location estimate during emergency procedures such as loss of communication link. This paper summarizes the evaluation of four categories of forecasting methodologies: subspace algorithms, autoregressive algorithms, nonlinear autoregressive using a wavelet network, and perturbation error methods. Simulated Model 5415 ship motion was evaluated in 24 conditions including sea states 4-6, ship speeds of 5, 10, 20, and 30 kts, and wave headings 150 and 180 deg (bow and head seas). For each condition, the simulation motion data was divided into twenty 7.5-minute segments consisting of 0.5 to 5 minutes of training data and 2.5 minutes of testing data. Two types of forecasting accuracy metrics were developed. One metric was based on forecasting simulated ship motion and the other metric involved forecasting periods when the motion exceeds threshold limits within a 4-second window, representing a quiescent period. The results indicate that for simulation forecast accuracy, the correlation coefficient between forecasted and actual motion was greater than 80% for 5-sec forecast horizons, and greater than 60% for 10-sec forecast horizons. For motion threshold forecasting, the forecasting accuracy was greater than 90% for 5-sec horizons and greater than 60% for 10-sec horizons. A qualitative assessment of both simulation and threshold metrics indicated that 80% accuracy produces a good forecast and 60% accuracy produces an acceptable forecast. Threshold forecasting can forecast the presence and duration of near-future quiescent periods, enabling safer, more efficient operations and reduced cost of ship-based aviation operations such as launch, recovery, and movement of aircraft.

A critical element to the evolving predictive capability is development of improved model forms that account for the complex interactions between the threat, armor, and human body. These improved models require validation data from appropriate experiments to insure accurate and representative simulation results, as well as the insights gained through analysis of experimental data. Thus to support the development of improved behind armor injury models, an experimental methodology was developed and executed in which the extent of injuries resulting from residual velocities of ballistic projectiles were directly measured; specifically dynamic pressure and strain during the wound cavity formation, collapse, and final depth of projectile penetration.

Unlike in-air propagation of electromagnetic fields, the finite conductivity of seawater results in a frequency-dependent phase velocity, attenuation, intrinsic impedance, and reflection and transmission coefficients at the ocean's surface. After giving a short summary of the electric and magnetic properties of the ocean, this chapter begins with Maxwell's equations and develops the mathematical descriptions of electromagnetic fields and dipole sources within a conducting media. The differences between plane wave reflection and transmission at the surface of fresh water and seawater are used to highlight how electromagnetic propagation within the electrically conducting ocean is so very different than the more familiar radio frequency transmissions in air. In addition, equations are presented that describe the fields from submerged electric and magnetic dipoles that are located both far and near the sea surface. These formulations are valid over the frequency range from 0 Hz to a few MHz. Finally, a brief discussion of ocean electromagnetics at optical wavelengths is given at the end of this chapter.

They typically do not demonstrate a consistent understanding of integrated diagnostics, or have an appreciation of the need. These same "fresh out" engineers will ultimately derive the low-level requirements for developing diagnostic systems, and this lack of knowledge of testing environments will have a significant impact. Failure to adequately address the integrated diagnostics and testing needs of a system greatly impacts its supportability and, consequently, the cost of that system throughout its life cycle. Integrated diagnostics is a career field for which there currently exists no standard set of basic qualifications, few educational opportunities to study at the university level, no clear processes within most organizations for practicing integrated diagnostics as a systems engineering activity, and no uniform method of sharing techniques and lessons learned with new employees. Studies have found that the majority of test engineer training is on-the-job, rather than knowledge acquired as part of a higher education degree program, or a formal training process [1]-[7]. As a result, it requires two to three years for any recent graduate to become competent in the field of test engineering. There are three main inhibiting factors to teaching design for testability as part of post-secondary education. The first factor is cost. The high cost, and quick obsolescence, of many ATE systems is a barrier to entry to any small-or medium-sized college's engineering department budget. Even accounting for corporate donations, there are hidden costs, such as facilities and equipment maintenance, which make ATE prohibitively expensive. Moreover, in the United States, all engineering curricula must be accredited by the Accreditation Board for Engineering and Technology (ABET). It is an arduous process, even for such well-worn topics as electrical engineering or mechanical engineering. A department chair is unlikely to risk the department's accreditation, or prolong the accreditation process, by including an exotic topic such as DFT or diagnostics. Finally, it is the goal of most institutions that their students will obtain employment upon graduation. To that end, curricula are often tailored to the demands of local employers. If surrounding industry is not asking for skilled diagnostic or DFT engineers, then there is no incentive for an engineering department to include it in a degree curriculum.

Industry research is now focused on breaking the historical construct of test equipment. Advances in the field of Synthetic Instruments have opened the door to test avionics in new ways. Every year new capabilities are developed using core hardware and increasingly capable software modules to create complex waveforms. This research creates a Digital Radio Frequency Memory (DRFM) Synthetic Instrument that can be programmed to perform a wide array of low latency Radio Frequency (RF) tests. Synthetic Instruments are defined as a concatenation of hardware and software modules used in combination to emulate a traditional piece of electronic instrumentation. This Synthetic Instrument couples high speed Analog-to-Digital Converters (ADC) to high speed Digital-to-Analog Converters (DAC) with Field Programmable Gate Arrays (FPGA) in between for digital signal processing. An RF front end is used to down convert the RF to baseband where it is sampled, modified, and up converted back to RF. The FPGA performs Digital Signal Processing (DSP) on the signal to achieve the desired output. Application of this DRFM in automated testing is demonstrated using a Reconfigurable Transportable Consolidated Automated Support System (RTCASS) tester at Naval Air Systems Command (NAVAIR) Jacksonville, FL. The Unit Under Test (UUT) is an ALQ-162 Defensive Electronic Countermeasures (DECM) receiver-transmitter. Ultra-low latency signals are generated to simulate enemy jamming stimulus. As the ALQ-162 detects and responds to the input, the DRFM switches to a new frequency. The time taken by the ALQ-162 to acquire, respond, and re-acquire is measured. This test confirms the internal Yttrium Iron Garnet (YIG) oscillator meets slew specifications. Currently Navy ATE can only test RF units using high latency steady state tests. This research project developed a supplemental unit that can be added to the VXI chassis in the CASS family of testers and conduct ultra-low latency active tests. The instrument acts as hardware-in-the-loop to perform real-time tests including a new capability to measure jamming response time from DECM avionics. Demonstrated performance capabilities include: latency < 100 ns, output Spurious-Free Dynamic Range (SFDR) > 80 dBc, input SFDR > 60 dBc, frequency tuning resolution < 2 Hz, and frequency settling time < 0.5 ns. New RF capabilities developed by this effort parallel similar research ongoing for digital test instruments like the Teradyne High Speed Subsystem. Incorporating this Digital RF Memory synthetic instrument into current and future ATE will improve readiness and supportability of the fleet. Improvements demonstrated by this research project will expand the type and quantity of assets able to be tested by current and future ATE.

The experimental parameters that may contribute to the difficulty can be summarized as: specimen width and thickness, interface coating thickness, mixed mode failure evolution, and interlaminar defects. Modes I crack growth resistances, G(1) were analytically determined at ambient temperature using wedge test, a modified double cantilever beam (DCB). Several Finite Element (FE) based Multi-scale modeling potential techniques were investigated: a) Multi-scale progressive failure analysis (MS-PFA); b) Virtual Crack Closure Technique (VCCT). Advantages and disadvantages of each were identified. The final modeling algorithm recommended was an integrated damage and fracture evolution methodology using combined MS-PFA and VCCT. The material tested in this study was a slurry-cast melt infiltrated SiC/SiC composite with Tyranno ZMI fibers (Ube Industries, Kyoto, Japan) and a BN interphase. The fiber architecture consisted of eight plies of balanced 2-D woven five-harness satin. The total fiber volume fraction was about 30% with half of the fibers in the 0 degrees direction and half in the 90 direction. All specimens had a nominal thickness of 4 mm. An alumina wedge with 18 degrees head angle (2 alpha) was used. In this method, a splitting force is created by inserting a vertically moving wedge in a notch causing the arms to separate and forcing an interlaminar crack at the sharpest end of the notch The MS-PFA numerical model predicted the damage and fracture evolution and utilized the GENOA UMAT (User Material Subroutine) for Damage and FEM (Finite Element Model) stress intensity and LEFM (Linear elastic Fracture Model), Cohesive Model for Fracture. The analysis results (Fracture energy vs. crack length, Fracture energy vs. load, Fracture energy vs. crack opening displacement) matched the Mode I coupon tests and revealed the following key findings. Mode I-Wedge specimen exhibits: 1) failure mode is due to interlaminar tension (ILT) only in the interface section and a zig-zag pattern observed; 2) VCCT crack growth resistance is well matched to the test data; and 3) failure mode is a mixed mode behavior of Interlaminar tension (ILT) to interlaminar shear (ILS). The final Wedge test specimen configuration optimization includes the sensitivity of design parameters to CGR: a) wedge contact coefficient of friction; b) lever arms thickness, and c) inclined head angle, distance between the initial crack and wedge tip.

Experiments, nondestructive evaluations (NDE), and simulations have illustrated good correlations between impact energy and foreign object damage (FOD) and fatigue life after impact at room and 1200 degrees C temperatures. Flat and curved five-harness satin (5HS) woven CMCs specimens, consisting of Hi-Nicalon Type S (Goodrich) and Hi-Nicalon (Rolls Royce) in MI SiC matrix, were tested and simulated. Tests measured electrical resistivity (ER), acoustic emission (AE), and microscopy. Simulations used a building block validation strategy and the Multi-Scale Progressive Failure Analysis (MS-PFA) method. Simulations complemented experiments in understanding and predicting the damage states, of impact, and fatigue residual strength after impact of CMCs to form a more complete understanding of the damage mechanisms involved in such events. The GENOA software developed by Alpha STAR Corporation [1, 2, 3] is capable of Durability and Damage Tolerance (D&DT), life, and reliability predictions by means of multi-scale progressive failure analysis (damage and fracture evolution). In general, CMCs are modeled using effective fiber, matrix, and interface constitutive behaviors, from which the lamina stiffness, strengths, and the strain rate effect can be derived. Similarly, the fatigue strength and stiffness degradation, and the effect of defects in a matrix micro crack density, voids, as well as fibers waviness, and damages after impact can be characterized. The final simulation is static loading and impact on a generic CMC SiC/SiC (Sylramic MI 5HS) blade which is to be used in future blade optimization based on minimizing damage incurred. The GENOA software platform supports FAA recommended ASTM standard Building-Block Validation Strategy with reduced tests conducting: 1) Material Calibration and Qualification, and 2) FEM Verification, Validation, and 3) Blind Predictions (Accreditation). The simulation and test comparisons performed included the damage size for both the CMC (fracture) and the steel impactor (plastic deformation), rebound velocities, SN curves for fatigue of pristine and impacted specimens at room and high temperatures. All simulations showed good correlation. The MS-PFA tool demonstrated a great potential for CMC post FOD fatigue life for part certification supported with reduced tests.

In this study, ER of woven silicon carbide fiber-reinforced silicon carbide composite systems in their pristine and impacted state were measured under cyclic loading conditions at room and high temperature (1200C). In addition, modal acoustic emission (AE) was also monitored, which can reveal the occasion of matrix cracks and fiber. ER measurement and AE technique are shown in this study to be useful methods to monitor damage and indicate the failure under cyclic loading. Based on the slope of the ER evolution, an initial attempt has been made to develop a method allowing a critical damage phase to be identified. While the physical meaning of the critical point is not yet clear, it has the potential to allow the failure to be indicated at its early stage.

The CMC targets were subject to ballistic impact at a normal incidence angle while being loaded under different levels of tensile loading in order to simulate conditions of rotating aeroengine airfoils. The impact damage of frontal and back surfaces was assessed with respect to impact velocity and load factor. Subsequent post-impact residual strength was also estimated to determine quantitatively the severity of impact damage. Impact force was predicted based on the principles of energy conservation.

Assessments of thermal stability of the samples were made using weight change, oxidation, microstructural evolution, and post-exposure mechanical properties such as Vickers microhardness and compressive yield stress. The three samples included bare Alloy "A" (9Cr-6A1-1.5Hf), Alloy "A" with.an overlay coating, and bare Alloy "B" (12Cr-3A1), were not much different in compositions. At 1850F, oxidation as measured by weight change was insignificant up to 2000 h in all the three samples. At 2000F, however, noticeable weight change occurred, increasing linearly with time all in the three samples. The oxidation penetration from surface to matrix for these samples was more intense when exposed to above 1000 hours, forming various oxides, gamma-prime (Upsilon') depletion zones, and TCP phases. The size and area fraction of Upsilon' precipitates were determined as a function of temperature and exposure time. Post-exposure mechanical properties were also assessed through Vickers hardness and compressive yield stress. A maximum change in Vickers hardness was about 10% at both temperatures up to 2000 hrs. The change in compressive yield stress was more pronounced than the change in Vickers hardness as a function of thermal exposure and time. C1 [Shifler, D. A.] Off Naval Res, Arlington, VA 22203 USA.

The experiments have been performed in the JHU optically index-matched facility, where the refractive index of the fluid is matched with that of the acrylic rotor blades and casing, facilitating unobstructed Stereo Particle Image Velocimetry (SPIV) measurements. The blade geometries are based on the first one and a half stages of the Low Speed Axial Compressor (LSAC) facility at NASA Glenn. The tip gap sizes are 0.49% and 2.3% of the blade chordlength, and measurements are performed for two flow rates, the lower of which is just above stall conditions. The presence and trajectories of the tip leakage vortex (TLV) and secondary structures are visualized by recording high speed movies of cavitation at lower pressures. The results consist of performance curves, distributions of velocity, circumferential vorticity and turbulent kinetic energy, as well as the strength and trajectory of vortices. Increasing the tip gap reduces the static-to-static pressure coefficient for all flow conditions. For the higher flow rate, a wider tip gap has several effects: (i) It delays the rollup of the TLV and its detachment from the suction side (SS) corner of the blade, presumably due to the larger distance from the endwall casing and the 'image vortex'. (ii) It alters the blade loading and reduces the circulation shed from the blade. (iii) It delays the onset of TLV bursting in the aft part of the rotor passage. (iv) For both gaps, the endwall boundary layer separates at the point where the leakage flow meets the opposite-direction main passage flow. For the wide gap, the separated layer with opposite sign vorticity remains above the TLV; while for the narrow gap, the TLV entrains this layer around itself. And (v) consistent with the major differences in flow structure, the spatial distributions and magnitudes of all the turbulence intensity are also very different. Trends and flow structure are quite different at pre-stall conditions. Most notably, TLV rollup is still delayed for the wide gap, but vortex bursting and associated arrival of multiple secondary structures to the pressure side (PS) of the next blade occur earlier. Consequently, the turbulence level on both sides of the blade tip is substantially higher, and remnants of the previous TLV are ingested into the next tip gap.

Cameras are effective in clear water, but have extremely poor performance in degraded visual environments (DVEs) such as turbid coastal waters and harbors. This is due to the multiple scattering of the light from the particulates and organic matter in the water. Laser-based sensors have been developed to enhance optical imaging in DVEs1,3,4,5,6. However, since conventional approaches require that the illuminator and receiver be located on the same platform, the size, weight, and power (SWaP) requirements are incompatible with small ROVs. Researchers at NAVAIR have developed a low cost optical imager utilizing a bistatic geometry where the illuminator and receiver are mounted on separate, smaller platforms. The illuminator steers a modulated laser beam with a microelectromechanical system (MEMS) scanner to sequentially illuminate an underwater object. A distant receiver collects the object reflected laser light and reconstructs the imagery. Communications information, including a synchronization sequence, is encoded onto the modulation which is used by the receiver to build the image. The SWaP of the illuminator's components have been optimized and integrated into a modified version of the OpenROV, a miniature, commercial off-the-shelf ROV. This paper reports on the efforts to reduce the SWaP of the modulated illuminator and the results of testing this system in a laboratory water tank environment.

Independent component analysis is a statistical signal processing technique which can separate a return of interest from clutter in a statistical domain. After highlighting the statistical processing concepts, we demonstrate that underwater lidar target and backscatter returns have very different distributions, facilitating their separation in a statistical domain. Example profiles are provided showing the results of this separation, and ranging experiment results are presented. In the ranging experiment, performance is compared to a more conventional frequency-domain filtering approach. Target tracking is maintained to 14.5 attenuation lengths in the laboratory test tank environment, a 2.5 attenuation length improvement over the baseline.

The system uses two recently introduced, low-cost, commercially available 462 nm multimode InGaN laser diodes, which are synchronized by a bi-directional optical link. This synchronization results in a noise-like chaotic intensity modulation with over 1 GHz bandwidth and strong modulation depth. An advantage of this approach is its simple transmitter architecture, which uses no electrical signal generator, electro-optic modulator, or optical frequency doubler.

While this groundbreaking work successfully showed that it is possible to cool solids using laser cooling, rare-earth materials are governed by Boltzmann statistics limiting their cooling ability to about 100 K. Direct-bandgap semiconductors, on the other hand, are governed by Fermi-Dirac statistics, which allows for a theoretical cooling limit of 10 K as well as higher cooling efficiencies. Recently, it was demonstrated that it is possible to cool CdS nanoribbons by 40 K. That success was attributed to CdS strong electron-phonon coupling, which makes it possible to resonantly annihilate more than one longitudinal optical phonon during each up conversion cycle. To further increase the cooling power, large external quantum efficiency is required. A nanostructure is preferred because it creates confined excitons of tunable wavelength and reduces the self-absorption of the anti-Stokes fluorescence owing to the shorter path length for photons to escape the crystal. However, organically passivated quantum dots have a low quantum yield due to surface related trap states. A core-shell nanostructure alleviates this problem by passivating the surface trap states and protecting against environmental changes and photo-oxidative degradation. As such, we chose to investigate CdSe/ZnS core shell structure for laser cooling applications. This article highlights the measurement of the anti-Stokes luminescence, the dependence of the laser wavelength on the anti-Stokes emission of colloidal quantum dots, and the successful incorporation of CdSe/ZnS into polymers.

In order to examine the effects of blast injury on hearing sensitivity, we developed a large database composed of demographic, audiometric, point of injury, and medical outcome data, with the primary aim of developing a long-standing and integrated capability for the surveillance, assessment, and investigation of blast -related hearing outcomes. Methods used to develop the dataset are described. Encompassing more than 16,500 Navy and Marine Corps personnel, the Blast -Related Auditory Injury Database (BRAID) includes individuals with a blast -related injury and nonblast control subjects. Using baseline and postdeployment hearing threshold data, a retrospective analysis of the cohort revealed that the rate of hearing loss for the injured service members was 39%. The BRAID will be useful for studies that assess hearing patterns following deployment -related injury, such as blast exposures, that facilitate exploration of health outcomes and whether they are predictive of audiometric disposition and that help establish hearing loss prevention strategies and program policies for affected military commands and servicemembers.

However, existing quality assessment tools either fail to account for proper technical quality and patient selection or are not validated. We developed and validated a simple scale for ESIs to provide a quality assessment and rating of technique for injections of the spine (AQUARIUS). Methods: Seven experts generated items iteratively based on prior ESI technique studies and professional judgment. Following testing for face and content validity, a 17-item instrument was used by 8 raters from 2 different backgrounds to assess 12 randomized controlled trials, selected from 3 different categories. Using frequency of assessment, a 12-item instrument was also generated. Both instruments underwent reliability (intraclass correlation coefficient), validity (ability to distinguish "low," "random," and "high" study categories), and diagnostic accuracy (receiver operating characteristics) testing. Results: Both 17- and 12-item instruments were scored consistently by raters regardless of background, with overall intraclass correlation coefficients of 0.72 (95% confidence interval [CI], 0.53-0.89) and 0.71 (95% CI, 0.51-0.89), respectively. Both instruments discriminated between clinical trials from all 3 categories. Diagnostic accuracy was similar for the 2 instruments, with areas under receiver operating characteristic curves of 0.89 (95% CI, 0.82-0.96) and 0.90 (95% CI, 0.82-0.97), respectively. Conclusions: The instrument in both 17- and 12-item formats demonstrates good reliability and diagnostic accuracy in rating ESI studies. As a complement to other tools that assess bias, the instrument may improve the ability to evaluate evidence for systematic reviews and improve clinical trial design.

TI Performance of a Portable Sleep Monitoring Device in Individuals with High Versus Low Sleep Efficiency SO JOURNAL OF CLINICAL SLEEP MEDICINE LA English DT Article DE automated analyses; mobile sleep assessment; sleep monitoring; sleep staging ID AUTOMATED WIRELESS SYSTEM; DRY HEADBAND TECHNOLOGY; HEALTHY-ADULTS; VALIDATION; ACTIGRAPHY; AGREEMENT; INSOMNIA; KAPPA AB Study Objectives: Portable and automated sleep monitoring technology is becoming widely available to consumers, and one wireless system (WS) has recently surfaced as a research tool for sleep and sleep staging assessment outside the hospital/laboratory; however, previous research findings indicate low sensitivity for wakefulness detection. Because difficulty discriminating between wake and sleep is likely to affect staging performance, we sought to further evaluate the WS by comparing it to the gold-standard polysomnography (PSG) and actigraphy (ACT) for overall sleep/wakefulness detection and sleep staging, within high and low sleep efficiency sleepers. Methods: Twenty-nine healthy adults (eight females) underwent concurrent WS, PSG, and ACT assessment in an overnight laboratory study. Epoch-byepoch agreement was determined by comparing sleep/wakefulness decisions between the WS to both PSG and ACT, and for detection of light, deep, and rapid eye movement (REM) sleep stages between the WS and PSG. Results: Sensitivity for wakefulness was low (40%), and an overestimation of total sleep time and underestimation of wake after sleep onset was observed. Prevalence and bias adjusted kappa statistic indicated moderate-to-high agreement between the WS and PSG for sleep staging. However, upon further inspection, WS performance varied by sleep efficiency, with the best performance during high sleep efficiency. Conclusions: The benefit of the WS as a sleep monitoring device over ACT is the ability to assess sleep stages, and our findings suggest this benefit is only realized within high sleep efficiency. Care should be taken to collect data under conditions where this is expected.

These negative consequences provide a unifying purpose for the maritime industry and biosecurity managers to prevent biofouling accumulation and transfer, but important gaps exist between these sectors. This mini-review examines the approach to assessments of ship biofouling among sectors (industry, biosecurity and marine science) and the implications for existing and emerging management of biofouling. The primary distinctions between industry and biosecurity in assessment of vessels biofouling revolve around the resolution of biological information collected and the specific wetted surface areas of primary concern to each sector. The morphological characteristics of biofouling and their effects on propulsion dynamics are of primary concern to industry, with an almost exclusive focus on the vertical sides and flat bottom of hulls and an emphasis on antifouling and operational performance. In contrast, the identity, biogeography, and ecology of translocated organisms is of highest concern to invasion researchers and biosecurity managers and policymakers, especially as it relates to species with known histories of invasion elsewhere. Current management practices often provide adequate, although not complete, provision for hull surfaces, but niche areas are well known to enhance biosecurity risk. As regulations to prevent invasions emerge in this arena, there is a growing opportunity for industry, biosecurity and academic stakeholders to collaborate and harmonize efforts to assess and manage biofouling of ships that should lead to more comprehensive biofouling solutions that promote industry goals while reducing biosecurity risk and greenhouse gas emissions.

The scarcity of recent naval combat data makes accurate forecasting difficult. Furthermore, current forecasts are based on single injuries only, even though empirical evidence indicates most battle casualties suffer multiple injuries. These anticipated single-injury casualty streams underestimate the needed medical resources. This article describes a method of simulating realistic multi-injury casualty streams in a maritime environment by combining available shipboard data with ground combat blast data. The simulations, based on the Military Combat Injury Scale, are expected to provide a better tool for medical logistics planning.

Unfortunately, conventional magnetic resonance imaging (MRI) findings and clinical symptoms do not necessarily correlate in the lumbar spine. With upright imaging, disc pathologies or foraminal stenosis may become more salient, leading to improvements in diagnosis. Materials and Methods: Seventeen adults (10 asymptomatic and 7 symptomatic volunteers) provided their informed consent and participated in the study. A 0.6T upright MRI scan was performed on each adult in the seated position. Parameters were obtained from the L2/3 level to the L5/S1 level including those pertaining to the foramen [cross-sectional area (CSA), height, mid-disc width, width, thickness of ligamentum flavum], disc (bulge, height, width), vertebral body (height and width), and alignment (lordosis angle, wedge angle, lumbosacral angle). Each parameter was compared based on the spinal level and volunteer group using two-factor analysis of variance (ANOVA). Bonferroni post hoc analysis was used to assess the differences between individual spinal levels. Results: Mid-disc width accounted for 56% of maximum foramen width in symptomatic volunteers and over 63% in asymptomatic volunteers. Disc bulge was 48% greater in symptomatic volunteers compared to asymptomatic volunteers. CSA was generally smaller in symptomatic volunteers compared to asymptomatic volunteers, particularly at the L4-L5 and L5-S1 spinal levels. Thickness of ligamentum flavum (TLF) generally increased from the cranial to caudal spinal levels where the L4-L5 and L5-S1 spinal levels were significantly thicker than the L1-L2 spinal level. Conclusions: The data implied that upright MRI could be a useful diagnostic option, as it can delineate pertinent differences between symptomatic volunteers and asymptomatic volunteers, especially with respect to foraminal geometry.

In a relatively straightforward way, the materiel necessary to treat a stream of patients can be calculated by summing across the supplies necessary for each malady in any given patient stream. This method was formalized by the Naval Health Research Center in the patented process embodied in the Estimating Supplies Program. The success of this method depends on an accurate probability estimate for the occurrence of each illness and trauma. There are several methods for estimating these discrete probabilities. This paper documents and defines the various types of estimates and explains the differences between them to reduce confusion and to standardize nomenclature.

We previously showed that the "AlPO4" coating promotes the formation of metal fluorides, which could act as a stable surface film and protect LiCoO2 from continuous degradation upon cycling. In this work, we removed the fluorine source in the LiPF6 salt by using the LiClO4 salt and investigated the effectiveness of the "AlPO4" coating. Interestingly, the "AlPO4" coating was found to improve the voltage efficiency and capacity retention when cycling in the LiPF6 electrolyte, but was detrimental when cycling in the LiClO4 electrolyte. XPS revealed that the "AlPO4" coating promotes the formation of metal fluoride in both electrolytes, with the surface film formed in LiClO4 being more electrically resistive compared to that formed in LiPF6. The source of fluorine in the coated electrode cycled in LiPF6 is largely attributed to the LiPF6 salt whereas the source of fluorine in the coated electrode cycled in LiClO4 is the binder PVDF. We believe that the coating could react with HF impurity in the LiPF6 electrolyte or from the binder PVDF and form stable metal fluoride films on the surface. (C) The Author(s) 2015.

Forty-six individuals were divided into three groups of resilience Low (LowRes), high (HighRes), and normal (Norm-Res), based on the Connor-Davidson Resilience Scale (2003). Participants then completed a task involving anticipation and experience of loaded breathing during functional magnetic resonance imaging (fMRI) recording. Compared to HighRes and NormRes groups, LowRes self-reported lower levels of interoceptive awareness and demonstrated higher insular and thalamic activation across anticipation and breathing load conditions. Thus, individuals with lower resilience show reduced attention to bodily signals but greater neural processing to aversive bodily perturbations. In low resilient individuals, this mismatch between attention to and processing of interoceptive afferents may result in poor adaptation in stressful situations. (C) 2015 Elsevier B.V.

TI Vaccine-associated reduction in symptom severity among patients with influenza A/H3N2 disease SO VACCINE LA English DT Article DE Influenza; Vaccine; Severity; Military ID ACUTE RESPIRATORY ILLNESS; LABORATORY-CONFIRMED INFLUENZA; VIRUS-INFECTION; CHILDREN; EFFICACY; ADULTS; SEASON; POPULATION; OUTPATIENT; VALIDATION AB Background: The moderate level of protection conferred by influenza vaccines is well-known, but the vaccine's ability to attenuate symptom severity among vaccinated individuals (i.e., vaccine failures) has not been established. Methods: We enrolled otherwise healthy adults who presented with influenza-like illness (ILI) at five US military hospitals between 2009 and 2014. Influenza was diagnosed and subtyped by PCR. Individual and composite severity scores were compared between those who had vs. had not received the seasonal influenza vaccine >14 days prior to enrollment. Results: A total of 155 cases of influenza (A/H1N1, n=69; A/H3N2, n=66; A/untyped, n=3; B, n=17) were identified, of whom 111(72%; A/H1N1, n =44; A/H3N2, n = 52; A/untyped, n=3; B, n =12) had been vaccinated. Women were significantly less likely to be vaccinated than men (49% vs. 89%; p< 0.01). In multivariate analysis, vaccinated individuals were significantly less likely to report a fever >101 degrees F (OR 0.24; 95% CI [0.10, 0.62]) and more likely to report myalgias (OR 3.31; 95% CI [1.22, 8.97]) than vaccinated individuals. Among patients with A/H3N2 infection, upper respiratory and total symptom severity scores were significantly lower for vaccinated patients during the first 2 days of illness, and differences in total symptom severity persisted over 7 days (p <0.05 for all comparisons). Differences across additional symptom categories (lower respiratory and systemic) were also observed throughout 7 days of illness in bivariate analyses. Differences in symptom severity were not observed between vaccinated and unvaccinated participants with A/H1N1 infection. Conclusions: Among patients with A/H3N2 infection, receipt of seasonal influenza vaccine was associated with reduced symptom severity. Patient-centered discussion about the benefits of influenza vaccination should be expanded to include the possibility that the vaccine could attenuate symptoms. (C) 2015 Elsevier Ltd.

TI Changes in Posttraumatic Cognitions Predict Changes in Posttraumatic Stress Disorder Symptoms During Cognitive Processing Therapy SO JOURNAL OF CONSULTING AND CLINICAL PSYCHOLOGY LA English DT Article DE posttraumatic stress disorder; depression; therapy; cognitive processing therapy; cognitions ID ADMINISTERED PTSD SCALE; VETERANS; VICTIMS AB Objective: Although cognitive processing therapy (CPT) has strong empirical support as a treatment for posttraumatic stress disorder (PTSD), studies have not directly examined the proposed change mechanisms that underlie CPT-that change in trauma-related cognitions produces change in PTSD and depression symptoms. To improve the understanding of underlying mechanisms of psychotherapeutic change, this study investigated longitudinal association between trauma-related cognitions, PTSD, and depression among veterans receiving CPT during a 7-week residential PTSD treatment program. Method: All 195 veterans met DSM-IV-TR diagnosis for PTSD. The sample was 53% male with a mean age of 48 years. Self-reported race was 50% White and 45% African American. The Posttraumatic Cognitions Inventory was used to assess trauma-related cognitions. The PTSD Checklist and Beck Depression Inventory-II were used to assess PTSD and depression, respectively. Cross-lagged panel models were used to test the longitudinal associations between trauma-related cognitions, PTSD, and depression. Measures were administered at three time points: pre-, mid-, and posttreatment. Results: Change in posttraumatic cognitions (self-blame; negative beliefs about the self) preceded change in PTSD. In addition, (a) change in negative beliefs about the self preceded change in depression, (b) change in depression preceded change in self-blame cognitions, and (c) change in depression preceded change in PTSD. Conclusion: Findings support the hypothesized underlying mechanisms of CPT in showing that change in trauma-related cognitions precedes change in PTSD symptoms. Results suggest that reduction of depression may be important in influencing reduction of PTSD among veterans in residential PTSD treatment.

TI A Study of Propeller Operation Near a Free Surface SO JOURNAL OF SHIP RESEARCH LA English DT Article DE propulsor hydrodynamics; free surface; oblique flow; computational fluid dynamics ID PHASE LEVEL SET; SIMULATION; FLOWS; TURBULENCE; GRIDS AB This paper presents a study of the effects of the interaction of the free surface with a marine propeller operating close to it, including the effects of depth and cross flow. Extensive simulations using the naval hydrodynamics computational fluid dynamics solver REX were conducted to study the open water characteristics, transient blade loads, and flow behavior of propeller 4661, with comparison to fully submerged experimental data at 0 degrees and 30 degrees shaft inclination with respect to the incoming flow. Deeply submerged computations and experiments show that the cross flow results in an increase in thrust and torque and lower efficiency relative to uniform inflow. Near the surface, computations show that effects on thrust and torque increase more dramatically as the propeller load increases. Furthermore, the presence of the free surface breaks the symmetry resulting in highest blade force losses when the blade is near top dead center. As the propeller approaches the surface, the amplitude of the higher harmonics of blade force increases. A demonstration calculation for a self-propelled submarine sailing deep and near the surface shows that operating closer to the surface results in higher propeller loads and lower efficiency.

Although an isolated propeller in open-water conditions can be simulated in a rotating reference frame, in a computation involving the body of an appended submarine, e.g., the relative motion needs to be properly treated. This increases the computational cost and reduces the accuracy/robustness of typical body-fitted approaches. In this work, an immersed boundary formulation is utilized to perform large-eddy simulations of a propeller in open-water conditions and in the presence of an upstream appendage at zero incidence. In such case, the requirement for the grid to conform to the moving body is relaxed solution is locally reconstructed to satisfy boundary conditions and efficient, conservative structured solvers can be used. This enables us to capture the detailed dynamics of the tip vortices and their footprint on the statistics of the wake. The influence of the upstream appendage is also assessed.

Military Service Members SO JOURNAL OF TRAUMATIC STRESS LA English DT Article ID POSTTRAUMATIC-STRESS-DISORDER; MILLENNIUM COHORT; PREVALENCE; AFGHANISTAN; VALIDATION; VETERANS; FATIGUE; ADULTS; MISUSE; DUTY AB Posttraumatic stress disorder (PTSD) is a prevalent condition among military service members and civilians who have experienced traumatic events. Stimulant use has been postulated to increase the risk of incident PTSD; however, research in this area is lacking. In this study, the association between receipt of prescription stimulants and PTSD was examined in a secondary analysis among active duty U.S. military members (n = 25,971), participating in the Millennium Cohort Study, who completed a baseline (2001-2003) and two follow-up surveys (between 2004-2008). Prescription stimulant data were obtained from the military Pharmacy Data Transaction Service. PTSD was assessed using the PTSD Checklist-Civilian Version and incident PTSD was defined as meeting the criteria at follow-up among those who did not have a history of PTSD at baseline. Overall, 1,215 (4.7%) persons developed new-onset PTSD during follow-up. Receipt of prescription stimulants were significantly associated with incident PTSD, hazard ratio = 5.09, 95% confidence interval [3.05, 8.50], after adjusting for sociodemographic factors, military characteristics, attention-deficit/hyperactivity disorder, baseline mental and physical health status, deployment experiences, and physical/sexual trauma. Findings suggested that prescription stimulants are associated with incident PTSD among military personnel; these data may inform the underlying pathogenesis of and preventive strategies for PTSD.

We examined STI prevalence and sexual behaviour in the predeployment time period (12 months prior) among recently deployed shipboard US Navy and Marine Corps military personnel. Methods Data were collected from 1938 male and 515 female service members through an anonymous, self-completed survey assessing sexual behaviours and STI acquisition characteristics in the past 12 months. Cross-sectional sex-stratified descriptive statistics are reported. Results Overall, 67% (n=1262/1896) reported last sex with a military beneficiary (spouse, n=931, non-spouse service member, n=331). Among those with a sexual partner outside their primary partnership, 24% (n=90/373) reported using a condom the last time they had sex and 30% (n=72/243) reported their outside partner was a service member. In total, 90% (n=210/233) reported acquiring their most recent STI in the USA (88%, n=126/143 among those reporting >= 1 deployments and an STI >= 1 year ago) and a significantly higher proportion (p<0.01) of women than men acquired the STI from their regular partner (54% vs 21%) and/or a service member (50% vs 26%). Conclusions Findings suggest a complex sexual network among service members and military beneficiaries. Findings may extend to other mobile civilian and military populations. Data suggest most STI transmission within the shipboard community may occur in local versus foreign ports but analyses from later time points in deployment are needed. These data may inform more effective STI prevention interventions.

Initially, inductive loops and high, permeability cored search coil sensors were installed beneath the seafloor, inside protective nonmagnetic tubes, to measure the magnetic signatures of ,of Ships, and to ,actively reduce them using a field cancellation technique called degaussing. Eventually, the sensor arrays were upgraded with triaxial magnetometers and, later with electric field sensors. The historical developments to improve the underwater electromagnetic measurement arrays from 1,940 to the present Will be along with a discussion of potential future innovations that might materialize.

TI The safety of early fresh, whole blood transfusion among severely battle injured at US Marine Corps forward surgical care facilities in Afghanistan SO JOURNAL OF TRAUMA AND ACUTE CARE SURGERY LA English DT Article; Proceedings Paper CT Scientific Assembly of the American-College-of-Emergency-Physicians (ACEP) CY OCT 27-30, 2014 CL Chicago, IL SP Amer Coll Emergency Phys DE Whole blood; transfusion; coagulopathy; mortality; apheresis platelets ID IMPROVED SURVIVAL; TRANEXAMIC ACID; TRAUMA PATIENTS; COMBAT; COAGULOPATHY; MILITARY; EXPERIENCE; OPERATIONS; PLATELETS; MEDICINE AB BACKGROUND In Afghanistan, care of the acutely injured trauma patient commonly occurred in facilities with limited blood banking capabilities. Apheresis platelets were often not available. Component therapy consisted of 1:1 packed red blood cells and fresh frozen plasma. Fresh, whole blood transfusion often augmented therapy in the severely injured patient. This study analyzed the safety of fresh, whole blood use in a resource-limited setting. METHODS A retrospective analysis was performed on a prospectively collected data set of US battle injuries presenting to three US Marine Corps (USMC) expeditionary surgical care facilities in Helmand Province, Afghanistan, between January 2010 and July 2012. Included in the review were patients with Injury Severity Scores (ISSs) of 15 or higher receiving blood transfusions. Univariate analyses were performed, followed by multivariable logistic regression to describe the relationship between the treatment group and posttreatment complications such as trauma-induced coagulopathy, infection, mortality, venous thromboembolism, and transfusion reaction. Propensity scores were calculated and included in multivariable models to adjust for potential bias in treatment selection. RESULTS A total of 61 patients were identified; all were male marines with a mean (SD) age of 23.5 (3.6) years. The group receiving fresh, whole blood was noted to have higher ISSs and lower blood pressure, pH, and base deficits on arrival. Traumatic coagulopathy was significantly less common in the group receiving fresh, whole blood (odds ratio, 0.01; 95% confidence interval, 0.00-0.18). Multivariable models found no other significant differences between the treatment groups. CONCLUSION The early use of fresh, whole blood in a resource-limited setting seems to confer a benefit in reducing traumatic coagulopathy. This study's small sample size precludes further statement on the overall safety of fresh, whole blood use. LEVEL OF EVIDENCE Therapy study, level IV.

The purpose of this preliminary study was to evaluate the feasibility and safety of providing U.S. military service members with a behavioral health treatment delivered directly to the home using videoconferencing.Materials and Methods:Ten previously deployed soldiers volunteered to complete eight sessions of a novel behavioral activation treatment for posttraumatic stress disorder. The primary clinical outcomes assessed included symptoms of posttraumatic stress and depression. Patient safety data and attitudes about seeking mental health services, treatment satisfaction, treatment adherence, and treatment compliance were also assessed.Results:Clinically significant reductions in posttraumatic stress symptom severity and depression symptoms were observed. Soldiers indicated high levels of satisfaction with the treatment, and there were no adverse events requiring activation of emergency safety procedures. Technical problems associated with the network were observed but successfully mitigated.Conclusions:The results provide initial support for the feasibility and safety of telemental health treatments delivered by videoconferencing to the homes of soldiers. The optimal technical infrastructure needs to be determined to support expansion of synchronous videoconferencing capabilities to the home. The findings provide preliminary evidence of the feasibility, safety, and high user satisfaction with home-based telemental health in the military setting.

These alignment changes (doglegs) are proposed to allow ships to reach deeper water in less distance, with reduced dredging costs. The Channel Analysis and Design Evaluation Tool (CADET) was used to predict the underkeel clearance and annual days of accessibility. The clearance and accessibility results were calculated for each channel option and include vertical ship motion allowances based on the wave-induced coupled heave, roll, and pitch. This provides a risk-based method of determining channel project depth based on two ship loading conditions for the three channel alignment options. Published by Elsevier Ltd. C1 [Briggs, M.

We recently reported that 5HTTLPR modulates cortisol response in healthy military men exposed to intense stress. Less is known of its combined effects with environmental factors in this context, or of its effect on neuroprotective stress responses. In this follow-up study, we examined the unique and combined effects of 5HTTLPR and prior trauma exposure on neuroprotective (salivary nerve growth factor [sNGF]), anabolic (dehydroepiandrosterone sulfate [DHEAS] and testosterone), and catabolic (cortisol) stress responses. Ninety-three healthy, active-duty military men were studied before, during, and 24 h after a stressful 12-day survival course. Distinct and interactive effects of 5HTTLPR long allele carriage [L] versus homozygous short allele carriage [SS]) and prior trauma exposure (low versus high) were evaluated, after which a priori group comparisons were performed between hypothesized high resilience (L/low) and low resilience (SS/high) groups. For sNGF, L/low produced the greatest sNGF throughout stress exposure while SS/high demonstrated the smallest; L/high and SS/low bisected these two extremes and were nearly identical to each other (i.e., SS/high < SS/low = L/high < L/low). Thus, 5HTTLPR and prior trauma exposure demonstrated counterbalancing (additive) forces. Similar patterns were found for DHEAS. To our knowledge, this study is the first to report counterbalancing genetic and environmental effects on novel biomarkers related to resilience in humans exposed to real-world stress. These findings have profound implications for health, performance and training in high-stress occupational settings. (C) 2015 Published by Elsevier Inc.

As its use becomes more widespread, it is important to understand the sensitivity of the extracted wave parameters to the characteristics of the radar and the scatterers. To examine such issues, experiments were performed offshore of the Scripps Institution of Oceanography pier in July 2010. Radar measurements in low wind speeds were performed with a dual-polarized high-resolution X-band pulse-Doppler radar at low grazing angles along with two independent measurements of the surface waves using conventional sensors, a GPS-based buoy, and an ultrasonic array. Comparison between radar cross section (RCS) and Doppler modulations shows peak values occurring nearly in-phase, in contrast with tilt modulation theory. Spectral comparisons between Doppler-based and RCS-based spectra show that Doppler-based spectra demonstrate greater sensitivity to swell-induced modulations, whereas RCS-based spectra show greater sensitivity to small-scale modulations (or generally have more noise at high frequency), and they equally capture energy at the wind wave peak. Doppler estimates of peak period were consistent with the conventional sensors, whereas the RCS differed in assignment of peak period to wind seas rather than swell in a couple of cases. Higher order period statistics of both RCS and Doppler were consistent with the conventional sensors. Radar-based significant wave heights are lower than buoy-based values and contain nontrivial variability of similar to 33%. Comparisons between HH and VV polarization data show that VV data more accurately represent the wave field, particularly as the wind speeds decrease.

TI Nucleation and growth model for {110}- and {111}-truncated nanoparticles SO JOURNAL OF MATERIALS RESEARCH LA English DT Article ID ULTRAFINE METAL PARTICLES; FERRITE NANOPARTICLES; CRYSTAL-SURFACES; GAS-EVAPORATION AB Nanoparticle-sized powders have seen more and more use in many of today's applications. As particle size decreases, many properties change including the ability to embed the small particles in liquids and other media. With decreasing size, however, surface energy becomes more important and can dictate the final shape of the particle. In applications based on polar molecules attaching to the nanoparticle surface, the surface morphology can become a key design parameter. A nucleation and growth model has been constructed for truncated body-centered cubic derivative materials, along with an update to previously published work on face-centered cubic materials. The model shows that for (110)- and (111)-truncations of a cube with a specified surface energy for each surface, the critical nuclei and equilibrium growth shapes are the same, supporting the theory of self-similar growth that had only been mentioned previously, but never proven. In this analysis, saddle points play an important role in determining the critical nuclei for comparison with the equilibrium growth shapes.

This functional dependence is presumably related to the giant flux-creep domain. It is shown that this constitutive relation reflects the statistical spread of the pinning potential associated with creep motion of vortex bundles. The AC losses emanating from a power-law constitutive relation are calculated in an approach focused on the superconductor's electric field. For a slab geometry in the presence of a parallel AC magnetic field or transport current, the calculated AC-loss scaling laws are consistent with BSCCO data and the critical state model.

The overall aims of the training were to provide discussion tools highlighting the experiences of Marines seeking help for stress concerns, improve communication between leaders and their Marines around the issue of help seeking, and familiarize Marines with behavioral health treatment. Senior enlisted leaders and officers (N = 52) from a Marine Corps battalion participated in a pretest, 2-h stigma-reduction training and immediate posttest. Acceptability of the training was measured by querying participants about the usefulness and helpfulness of the training among other factors, and stigma awareness was measured with 10 items about mental health stigma. The stigma-reduction training and materials were well accepted by participants. In addition, there was a significant improvement in four of ten stigma-reduction awareness concepts measured before and immediately after the training, which included an increase in agreement that mental health treatments are usually effective in reducing stress reactions [t(51) = -3.35, p = 0.002], and an increase in disagreement that seeking counseling after a deployment will jeopardize future deployments [t(51) = -3.05, p = 0.004]. Level of agreement with several statements including those regarding perceptions of invincibility, and malingering, among others, did not change significantly after the training. The stigma-reduction training containing educational and contact strategies was highly acceptable to the leaders and may have promise for initially dispelling myths associated with seeking help for stress concerns among military service members; however, results indicate that there is clearly more work to be done in combatting stigma.

TI Airway Management in Severe Combat Maxillofacial Trauma SO OTOLARYNGOLOGY-HEAD AND NECK SURGERY LA English DT Article DE tracheostomy; airway trauma; intubation; facial trauma; inhalation injury ID OPERATION-IRAQI-FREEDOM; PENETRATING NECK TRAUMA; INJURY SEVERITY; ENDURING-FREEDOM; SCORE; REGISTRY; DEATH; HEAD AB Objectives Airway stabilization is critical in combat maxillofacial injury as normal anatomical landmarks can be obscured. The study objective was to characterize the epidemiology of airway management in maxillofacial trauma. Study Design Retrospective database analysis. Setting Military treatment facilities in Iraq and Afghanistan and stateside tertiary care centers. Subjects In total, 1345 military personnel with combat-related maxillofacial injuries sustained March 2004 to August 2010 were identified from the Expeditionary Medical Encounter Database using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes. Methods Descriptive statistics, including basic demographics, injury severity, associated injuries, and airway interventions, were collected. A logistic regression was performed to determine factors associated with the need for tracheostomy. Results A total of 239 severe maxillofacial injuries were identified. The most common mechanism of injury was improvised explosive devices (66%), followed by gunshot wounds (8%), mortars (5%), and landmines (4%). Of the subjects, 51.4% required intubation on their initial presentation. Of tracheostomies, 30.4% were performed on initial presentation. Of those who underwent bronchoscopy, 65.2% had airway inhalation injury. There was a significant relationship between the presence of head and neck burn and association with airway inhalation injury (P < .0001). There was also a significant relationship between the severity of facial injury and the need for intubation (P = .002), as well as the presence of maxillofacial fracture and the need for tracheostomy (P = .0001). Conclusions There is a high incidence of airway injury in combat maxillofacial trauma, which may be underestimated. Airway management in this population requires a high degree of suspicion and low threshold for airway stabilization.

TI Carbon Nanotube Based Sensor to Monitor Crack Growth in Cracked Aluminum Structures Underneath Composite Patching SO APPLIED COMPOSITE MATERIALS LA English DT Article DE Crack sensor; Composite patching; Carbon nanotubes ID ELECTRICAL-PROPERTIES; NETWORKS; MATRIX AB The paper investigates a carbon nanotube-based sensor to detect crack propagation in aluminum structures underneath composite patching. Initial tests are conducted to determine the correct procedure and materials to properly fabricate a carbon nanotube (CNT) based sensor, which is then placed in between a composite patch and the aluminum structure. The CNTs have been utilized as sensors in previous studies but only for sensing crack propagation within the composite itself. This study focuses on crack propagation in the base material and is not concerned with the composite. In this application, the composite is only a patch and can be replaced if damaged. The study conducts both tension and fatigue testing to determine the usefulness of the CNT sensor. The CNT sensor is shown to be effective in giving an indication of the crack propagation in the aluminum. Correlation is done between the crack propagation length and the increase in electrical resistance in the CNT sensor under tensile and cyclic loading, respectively. C1 [Olson, T. M.; Kwon, Y.

The circulation of human adenovirus type 21 (HAdV21) in the United States has been documented since the 1960s in association with outbreaks of febrile respiratory illness (FRI) in military boot camps and civilian cases of respiratory disease. Methods.aEuro integral To describe the molecular epidemiology of HAdV21 respiratory infections across the country, 150 clinical respiratory isolates obtained from continuous surveillance of military recruit FRI, and 23 respiratory isolates recovered from pediatric and adult civilian cases of acute respiratory infection were characterized to compile molecular typing data spanning 37 years (1978-2014). Results.aEuro integral Restriction enzyme analysis and genomic sequencing identified 2 clusters of closely related genomic variants readily distinguishable from the prototype and designated 21a-like and 21b-like. A-like variants predominated until 1999. A shift to b-like variants was noticeable by 2007 after a 7-year period (2000-2006) of cocirculation of the 2 genome types. US strains are phylogenetically more closely related to European and Asian strains isolated over the last 4 decades than to the Saudi Arabian prototype strain AV-1645 isolated in 1956. Conclusions.aEuro integral Knowledge of circulating HAdV21 variants and their epidemic behavior will be of significant value to local and global FRI surveillance efforts.

It was determined that the proper combination of reaction time and temperature allows for the control of PbSe nanorod length and diameter and therefore control over their electronic states, as probed through absorbance and photoluminescence measurements. Similar to PbSe nanowires, nanorods display higher Stokes shifts than for spherical nanocrystals due to intrananorod diameter fluctuations.

The catalyst for this project was a new ship class requirement to have an Unrep system that could deliver current system loads at twice the speed or twice as heavy loads at current systems speeds, Heavy E-STREAM (Electronic-Standard Tensioned REplenishment Alongside Method). Legacy technologies proved to be ineffectual for these difficult requirements while modern components and electronic controls proved highly capable to solve this complex at-sea, intership cargo transfer system. Obsolescence and maintenance issues with the legacy system, along with demonstrated performance gains and proposed engineering improvements reducing Total Ownership Costs (TOC) of this new system, led to the sponsor tasking development of two additional Unrep systems, one fuel and one cargo. These systems would be designed with legacy capability, utilizing the controls developed during the Heavy E-STREAM, maximizing any development work put into reducing TOC, and would become the Navy's new Standard Unrep system. These two new systems are E-STREAM Fueling-At-Sea (E-FAS) and E-STREAM Cargo (E-RAS - E-STREAM Replenishment-At-Sea). The following paper discusses why and how the system was modernized, how the new design will decrease maintenance requirements, both preventative and corrective, and what the current status is of the system development.

For this reason multiple companies have designed traps to specifically target those species. Recently the standard trap for DENV and CHIKV vectors, the BG-Sentinel (BGS) trap, has been remodeled to be more durable and better suited for use in harsh field conditions, common during military operations, and relabeled the BG-Sentinel 2 (BGS2). This new trap was evaluated against the standard Centers for Disease Control and Prevention (CDC) light trap, Zumba Trap, and BG-Mosquitito Trap to determine relative effectiveness in collecting adult Aedes aegypti and Ae. albopictus. Evaluations were conducted under semifield and field conditions in suburban areas in northeastern Florida from May to August 2014. The BGS2 trap collected more DENV and CHIKV vectors than the standard CDC light trap, Zumba Trap, and BG-Mosquitito Trap, but attracted fewer species, while the BG-Mosquitito Trap attracted the greatest number of mosquito species.

Exactly 475 nightmares and 433 unpleasant dreams were collected from Dreamboard users, while 135 nightmares were collected from individuals who reported having recurrent nightmares via a SurveyMonkey survey. Results demonstrated that physical aggression and anxiety levels were significantly higher for nightmares from individuals who reported recurrent nightmares relative to nightmares from people not reporting recurrent nightmares who in turn reported nightmares, which evidenced higher physical aggression levels relative to unpleasant dreams. Use of personal pronouns, verbs, and social terms were significantly reduced in recurrent nightmares relative to regular nightmares and unpleasant dreams. Aggressors were most often supernatural agents in recurrent nightmares; unfamiliar males in regular nightmares and familiar males in unpleasant dreams. Physical aggression against the dreamer was the most common theme in nightmares while interpersonal conflict was the most common theme in unpleasant dreams. Nightmares associated with awakenings evidenced significantly higher levels of aggression relative to nightmares not associated with awakenings. People with recurrent nightmares were 3 times more likely to report a relative on their maternal side with recurrent nightmares. We conclude that levels of physical aggression within the dream and targeted against the dreamer distinguishes recurrent from nonrecurrent nightmares and unpleasant dreams.

A 2-way multivariate analysis of variance (MANOVA) was conducted to explore the relationship of hardiness dimensions on several psychological and physical factors. Compared with other military samples, this cohort reported similar levels on hardiness control and rigidity subscales. Recruits who reported higher scores on a measure of positive hardiness also reported higher scores on measures of grit, grit ambition, sensation seeking, training expectations, positive ways of coping, physical and mental health, fitness scores, and lower scores on a measure of depression. This study provides a more complete understanding of the complex array of attributes of Marine recruits and forms a foundation for predictive models of injury risk and/or attrition.

US military members from the Millennium Cohort Study deployed in support of the recent operations were followed for approximately 7 years from baseline through 2 follow-up periods between 2001 and 2008. Propensity score matching was used to match 1 male to each female using demographic, military, and behavioral factors including baseline sexual assault. Analyses were stratified by combat experience defined as reporting at least one of five exposures during follow-up. Outcome measures included a positive screen for PTSD and severity scores measured by the PTSD Patient Checklist Civilian Version. Discrete-time survival analysis quantified the association between gender and incident PTSD. Among 4684 matched subjects (2342 women and men), 6.7% of women and 6.1% of men developed PTSD during follow-up. Results showed no significant gender differences for the likelihood of developing PTSD or for PTSD severity scores among women and men who reported combat experience and among those who did not. This study is the first of its kind to match a large population of male and female service members on important baseline characteristics including sexual assault. Findings suggest that while combat deployed personnel develop PTSD, women do not have a significantly different risk for developing PTSD than men after experiencing combat. Published by Elsevier Ltd.

TI Postpartum depression and timing of spousal military deployment relative to pregnancy and delivery SO ARCHIVES OF GYNECOLOGY AND OBSTETRICS LA English DT Article DE Postpartum depression; Women's health; Military deployment; Mental health ID BIRTH-DEFECTS SURVEILLANCE; MATERNAL DEPRESSION; TREATMENT FACILITY; PRIMARY-CARE; RISK-FACTORS; HEALTH; WIVES; SYMPTOMS; IMPACT; PREVALENCE AB This study aimed to determine the relationship between spousal deployment and postpartum depression diagnosis among U.S. military wives, accounting for the timing of deployment with respect to pregnancy and delivery. A retrospective cohort study was conducted to evaluate the association between spousal deployment and postpartum depression among pregnant wives of active-duty service members. Electronic medical records for 161,454 births occurring between 2004 and 2009 were used to define postpartum depression. Three non-mutually exclusive exposure variables were created to categorize deployments as occurring before, during, or after the infant's delivery. A multivariable logistic regression model mutually adjusted for these exposure variables was fitted, producing an odds ratio for each of the three timing categories. A modest significant association was detected only in those whose husbands deployed in pregnancy and returned after delivery (i.e., deployed during delivery) [odds ratio (OR) 1.10, 95 % confidence interval (CI) 1.04-1.15]. An interactive effect between preexisting depression or anxiety and deployment during delivery was also detected in the data (OR 1.13, 95 % CI 1.07-1.20 for those without a preexisting diagnosis; OR 0.87, 95 % CI 0.80-0.95 for those with a preexisting diagnosis). Health care providers should continue to be aware of spousal deployment as a military-unique stressor in this population and rigorously screen for potential symptoms of postpartum depression, especially among those whose husbands are absent at delivery.

Approximately 65% of NSVIPR participants also inadvertently received Anthrax Vaccine Adsorbed (AVA) while pregnant, providing a ready opportunity to evaluate pregnancy and infant health outcomes among these women. AVA-exposed pregnancies were ascertained using NSVIPR and electronic healthcare data. Rates of pregnancy loss and infant health outcomes, including major birth defects, were compared between AVA-exposed and AVA-unexposed pregnancies. Analyses included AVA-exposed and AVA-unexposed pregnant women who also received smallpox vaccine 28 days prior to or during pregnancy. Rates of adverse outcomes among the AVA-exposed group were similar to or lower than expected when compared with published reference rates and the AVA-unexposed population. The findings provide reassurance of the safety of AVA when inadvertently received by a relatively young and healthy population during pregnancy. (C) 2015 Elsevier Ltd. All rights reserved.

Here, the structure of stable silver carbon alloys is described, which are produced by thermoelectrically charging molten silver with carbon ions. Transmission electron microscopy and Raman scattering are combined to establish that large amount of carbon is accommodated in the form of epitaxial graphene-like sheets. The carbon bonds covalently to the silver matrix as predicted from density functional theory (DFT) calculations with bond energies in the range 1.1-2.2 eV per atom or vacancy. Graphitic-like sheets embedded in the crystal lattice of silver form 3D epitaxial structures with the host metal with a strain of approximate to 13% compared to equilibrium graphene. The carbon nanostructures persist upon remelting and resolidification. A DFT-based analysis of the phonon density of states confirms the presence of intense vibration modes related to the AgC bonds observed in the Raman spectra of the alloy. The solid silver-high carbon alloy, termed Ag-covetic, displays room temperature electrical conductivity of 5.62 x 10(7) S m(-1) even for carbon concentrations of up to approximate to 6 wt% (36 at%). This process of incorporation of carbon presents a new paradigm for electrocharging assisted bulk processing.

TI Improvements in dizziness and imbalance results from using a multi disciplinary and multi sensory approach to Vestibular Physical Therapy - a case study SO FRONTIERS IN SYSTEMS NEUROSCIENCE LA English DT Article DE CAREN; vestibular physical therapy; virtual reality; treadmill; traumatic brain injury; TBI ID TRAUMATIC BRAIN-INJURY; DYSFUNCTION; POSTURE AB This paper discusses a case study of a 41-year-old active duty male service member who sustained head trauma from a motorcycle accident and underwent multidisciplinary vestibular physical therapy rehabilitation. He was initially treated with traditional physical therapy applications of treadmill walking and standing balance with some symptom improvements, but was not able to maintain a running speed that would allow him to return to full active duty status. Further treatment utilizing a Computer Assisted Rehabilitation Environment was performed in order to increase level of difficulty and further enhance function. This treatment is able to elicit vestibular deficits seen in the community as it requires subjects to walk and balance while performing tasks within a virtual scenario incorporating platform motion, visual surround and flow, and cognitive processing. After 6 weeks of therapy, twice weekly, improvements in clinical vestibular measures were observed as well as walking speed and patient confidence. The patient was able to return to full duty after treatment. This case study provides supportive evidence that multidimensional tasking in a virtual environment provides a safe but demanding form of vestibular therapy for patients needing more challenging tasks than those provided with traditional therapy techniques. Those persons requiring higher levels of performance before returning to full duty (e.g., pilots, special operators, etc.) may find this type of therapy beneficial.

TI The LatMix Summer Campaign: Submesoscale Stirring in the Upper Ocean SO BULLETIN OF THE AMERICAN METEOROLOGICAL SOCIETY LA English DT Article ID INTERNAL WAVES; MIXED-LAYER; VERTICAL MOTION; PART I; DISPERSION; INSTABILITIES; SIMULATIONS; DISSIPATION; PYCNOCLINE; TURBULENCE AB Lateral stirring is a basic oceanographic phenomenon affecting the distribution of physical, chemical, and biological fields. Eddy stirring at scales on the order of 100 km (the mesoscale) is fairly well understood and explicitly represented in modern eddy-resolving numerical models of global ocean circulation. The same cannot be said for smaller-scale stirring processes. Here, the authors describe a major oceanographic field experiment aimed at observing and understanding the processes responsible for stirring at scales of 0.1-10 km. Stirring processes of varying intensity were studied in the Sargasso Sea eddy field approximately 250 km southeast of Cape Hatteras. Lateral variability of water-mass properties, the distribution of microscale turbulence, and the evolution of several patches of inert dye were studied with an array of shipboard, autonomous, and airborne instruments. Observations were made at two sites, characterized by weak and moderate background mesoscale straining, to contrast different regimes of lateral stirring. Analyses to date suggest that, in both cases, the lateral dispersion of natural and deliberately released tracers was O(1) m(2) s(-1) as found elsewhere, which is faster than might be expected from traditional shear dispersion by persistent mesoscale flow and linear internal waves. These findings point to the possible importance of kilometer-scale stirring by submesoscale eddies and nonlinear internal-wave processes or the need to modify the traditional shear-dispersion paradigm to include higher-order effects. A unique aspect of the Scalable Lateral Mixing and Coherent Turbulence (LatMix) field experiment is the combination of direct measurements of dye dispersion with the concurrent multiscale hydrographic and turbulence observations, enabling evaluation of the underlying mechanisms responsible for the observed dispersion at a new level.

TI Post-traumatic Stress Disorder Among Navy Health Care Personnel Following Combat Deployment SO MILITARY MEDICINE LA English DT Article ID AUSTRALIAN ARMY NURSES; ALLOSTATIC LOAD; BURNOUT; PROVIDERS; VIETNAM; ADAPTATION; DISEASE; ERRORS; WAR AB U.S. Navy health care personnel are exposed to an array of psychological stressors during combat deployment. This study compared rates of post-traumatic stress disorder (PTSD) among Navy health care personnel with nonhealth care personnel following single and repeated combat deployments. The study sample was identified from electronic records indicating deployment to Iraq, Kuwait, or Afghanistan, and included 3,416 heath care and 4,648 nonhealth care personnel. Health care personnel had higher PTSD rates and an increasing trend in PTSD rates across repeated deployments. After adjusting for combat exposure and other covariates, health care compared with nonhealth care personnel were more likely to be diagnosed with PTSD after one (odds ratio [OR] 2.02; 95% confidence interval [CI] 1.45-2.80), two (OR 2.27; 95% CI 1.26-4.08), and three deployments (OR 4.37; 95% CI 1.25-15.28). Exposure to wounded/dead friendly forces was associated with higher PTSD rates in health care personnel (OR 1.53; 95% CI 1.13-2.07). Health care personnel occupy a unique and essential role in current wartime operations, and are a high-risk group for PTSD. These findings suggest that further research is needed on the effects of caregiver stress, and refinements to postdeployment screening for health care personnel should be pursued.

TI CK-MM Polymorphism is Associated With Physical Fitness Test Scores in Military Recruits SO MILITARY MEDICINE LA English DT Article ID CREATINE-KINASE GENE; SKELETAL-MUSCLE; VARIANTS; EXERCISE; PERFORMANCE; STRENGTH AB Objective: Muscle-specific creatine kinase is thought to play an integral role in maintaining energy homeostasis by providing a supply of creatine phosphate. The genetic variant, rs8111989, contributes to individual differences in physical performance, and thus the purpose of this study was to determine if rs8111989 variant is predictive of Physical Fitness Test (PFT) scores in male, military infantry recruits. Methods: DNA was extracted from whole blood, and genotyping was performed in 176 Marines. Relationships between PFT measures (run, sit-ups, and pull-ups) and genotype were determined. Results: Participants with 2 copies of the T allele for rs8111989 variant had higher PFT scores for run time, pull-ups, and total PFT score. Specifically, participants with 2 copies of the TT allele (variant) (n = 97) demonstrated an overall higher total PFT score as compared with those with one copy of the C allele (n = 79) (TT: 250 +/- 31 vs. CC/CT: 238 +/- 31; p = 0.02), run score (TT: 82 +/- 10 vs. CC/CT: 78 +/- 11; p = 0.04) and pull-up score (TT: 78 +/- 11 vs. CC/CT: 65 +/- 21; p = 0.04) or those with the CC/CT genotype. Conclusion: These results demonstrate an association between physical performance measures and genetic variation in the muscle-specific creatine kinase gene (rs8111989).

The association of sexual trauma with health and occupational outcomes was investigated using longitudinal data from the Millennium Cohort Study. Of 13,001 U.S. service women, 1,364 (10.5%) reported recent sexual harassment and 374 (2.9%) recent sexual assault. Women reporting recent sexual harassment or assault were more likely to report poorer mental health: OR = 1.96, 95% CI [1.71, 2.25], and OR = 3.45, 95% CI [2.67, 4.44], respectively. They reported poorer physical health: OR = 1.39, 95% CI [1.20, 1.62], and OR = 1.39, 95% CI [1.04, 1.85], respectively. They reported difficulties in work/activities due to emotional health: OR = 1.80, 95% CI [1.59, 2.04], and OR = 2.70, 95% CI [2.12, 3.44], respectively. They also reported difficulties with physical health: OR = 1.55, 95% CI [1.37, 1.75], and OR = 1.52 95% CI [1.20, 1.91], respectively, after adjustment for demographic, military, health, and prior sexual trauma characteristics. Recent sexual harassment was associated with demotion, OR = 1.47, 95% CI [1.12, 1.93]. Findings demonstrated that sexual trauma represents a potential threat to military operational readiness and draws attention to the importance of prevention strategies and services to reduce the burden of sexual trauma on military victims.

Las mujeres que reportaron acoso sexual o abuso reciente fueron las que con mayor probabilidad reportaron salud mental mas deteriorada (OR = 1.96 95% CI [1.71, 2.25]; y OR = 3.45 95% CI [2.67,4.44], respectivamente), Salud fisica mas deteriorada(OR = 1.39 95% CI [1.20,1.62], y OR = 1.39 95% CI [1.04, 1.85], respectivamente), y dificultades en el trabajo/ actividades debido a la Salud emocional (OR = 1.80 95% CI [1.59, 2.04]; y OR = 2.70 95% CI [2.12-3.44], respectivamente) despues del ajuste por caracteristicas demograficas, militares, salud y trauma sexual previo. El acoso sexual reciente se asocio con descenso de categoria (OR = 1.47 95% CI [1.12, 1.93]. Los hallazgos demuestran que el trauma sexual representa una amenaza potencial para la preparacion operacion militar y llama la atencion sobre la importancia de las estrategias y los servicios de prevencion para reducir la carga de trauma sexual en victimas militares.

TI Analysis and Comparison of Single-Crystal and Polycrystalline Nd:YAG, Scatter SO IEEE JOURNAL OF QUANTUM ELECTRONICS LA English DT Article DE Polycrystalline YAG; single crystal YAG; Nd:YAG; optical properties; scatterance; BSDF; TIS; Kubelka-Munk; anomalous diffraction; ADA ID ND-YAG CERAMICS; LASER; PERFORMANCE; SILICA AB The extrinsic scatterance properties of polycrystalline and single crystal Nd:YAG materials are reported. Materials include undoped, 1%, 1.5%, 2%, 4%, and 6% Nd doped polycrystalline YAG, and undoped and 1% Nd doped single crystal YAG. The motivation of this study is to determine the ideal material type, and doping percentage gain media for use in 0.946 mu m Nd: YAG lasers. In-plane bidirectional scatterance distribution function measurements are collected at multiple wavelengths from 0.405 mu m to 1.55 mu m for all samples. Scatterance data is fit to standard models and a total integrated scatter (TIS) for each sample at various wavelengths is determined. Using the TIS at multiple wavelengths, some conclusions on material quality and suitability are presented. A coated sphere anomalous diffraction (ADA) model is developed and applied to known sources of scatter in polycrystalline and single-crystal Nd: YAG. A Kubelka-Munk wavelength-dependant scatter coefficient model is developed using our ADA model. The model provides an accurate estimate of scatter at 0.946 mu m. A comparison of strengths and weaknesses of single-crystal and polycrystalline materials is presented. This comparison reveals a possible continuing problem with background scatter present in single-crystal YAG.

TI Non-planar mixed-mode growth of initially straight-fronted surface cracks, in cylindrical bars under tension, torsion and bending, using the symmetric Galerkin boundary element method-finite element method alternating method SO FATIGUE & FRACTURE OF ENGINEERING MATERIALS & STRUCTURES LA English DT Article DE fatigue crack growth; round bar; SGBEM-FEM alternating method; stress intensity factor ID STRESS INTENSITY FACTORS; ENERGY-RELEASE RATES; FATIGUED ROUND BARS; ANALYSES SGBEM-FEM; FRACTURE-MECHANICS; SINGULAR TRACTION; CIRCULAR BAR; EDGE CRACK; EQUATION; INTEGRALS AB In this paper, the stress intensity factor (SIF) variations along an arbitrarily developing crack front, the non-planar fatigue-crack growth patterns, and the fatigue life of a round bar with an initially straight-fronted surface crack, are studied by employing the 3D symmetric Galerkin boundary element method-finite element method (SGBEM-FEM) alternating method. Different loading cases, involving tension, bending and torsion of the bar, with different initial crack depths and different stress ratios in fatigue, are considered. By using the SGBEM-FEM alternating method, the SIF variations along the evolving crack front are computed; the fatigue growth rates and directions of the non-planar growths of the crack surface are predicted; the evolving fatigue-crack growth patterns are simulated, and thus, the fatigue life estimations of the cracked round bar are made. The accuracy and reliability of the SGBEM-FEM alternating method are verified by comparing the presently computed results to the empirical solutions of SIFs, as well as experimental data of fatigue crack growth, available in the open literature. It is shown that the current approach gives very accurate solutions of SIFs and simulations of fatigue crack growth during the entire crack propagation, with very little computational burden and human-labour cost. The characteristics of fatigue growth patterns of initially simple-shaped cracks in the cylindrical bar under different Modes I, III and mixed-mode types of loads are also discussed in detail.

Twenty-nine Naval Special Warfare (NSW) Operators wore an actiwatch for an 8-day/7-night period for objective sleep assessment and completed a nightly sleep log. A total of 170 nights of actigraphically recorded sleep were collected. When comparing objectively versus subjectively recorded sleep parameter data, statistically significant differences were found. Compared with sleep log data, actigraphy data indicate NSW Operators took longer to fall asleep (an average of 25.82 minutes), spent more time awake after sleep onset (an average of 39.55 minutes), and demonstrated poorer sleep efficiency (83.88%) (ps < 0.05). Self-reported sleep quality during the study period was 6.47 (maximum score = 10). No relationships existed between the objectively derived sleep indices and the self-reported measure of sleep quality (rs = -0.29 to 0.09, all ps > 0.05). Strong inter-relationships existed among the subjectively derived sleep indices (e.g., between self-reported sleep quality and sleep efficiency; r = 0.61, p < 0.001). To our knowledge, this is the first study to objectively and subjectively quantify sleep among NSW Operators. These findings suggest sleep maintenance and sleep efficiency are impaired when compared to normative population data.

Research design: Participants were male, US military personnel treated in Afghanistan within 4 days following an IED-related mTBI event (n=239). Methods and procedures: Demographics, diagnosis of ASR, injury history and self-reported mTBIs, blast exposures and psychological health histories were recorded. Main outcomes and results: In total, 12.5% of patients met ASR criteria. Patients with ASR were significantly younger and junior in rank (p<0.05). Patients with ASR were more likely to experience the IED-blast while dismounted, report a loss of consciousness (LOC) and higher pain levels (p<0.05). Adjusting for age and rank, multivariate logistic regression showed an association between mTBI history and ASR (AOR = 1.405; 95% CI = 1.105-1.786, p<0.01). Adjusting for mechanism of injury (dismounted vs. mounted), LOC and pain, multivariate logistic regression showed an association between mTBI history and ASR (AOR = 1.453; 95% CI = 1.132-1.864, p<0.01). Prior blast exposure and past psychological health issues were not associated with ASR. Conclusions: A history of multiple mTBIs is associated with increased risk of ASR. Future research is warranted. C1 [Norris, Jacob N.] Naval Med Res Ctr, Neurotrauma Dept, Silver Spring, MD 20910 USA. [Smith, Scottie] Branch Hlth Clin Kings Bay, Kings Bay, GA USA.

Millions of soldiers around the world represent one of the most vulnerable populations regarding exposure to human immunodeficiency virus (HIV) infection. The programs for HIV prevention remain the most viable approach to reducing the spread of HIV infection. Very few studies have tested the effectiveness of HIV preventive interventions undertaken in military population. The aim of this study was to determine the effectiveness of educational film to transfer knowledge about HIV infection to soldiers. Methods. We performed a quasi-experimental study among 102 soldiers of the Serbian Armed Forces. The experimental intervention consisted of the HIV knowledge prequestionnaire, watching a film on HIV knowledge, then the post-HIV knowledge questionnaire. The results of pre-and post-HIV knowledge questionnaires were compared. Results. There were 23 questions in the test. The average total score on the questionnaire before watching the film was 18.23 and after watching it was 20.14, which was statistically significant difference (p < 0.001). Conclusions. The results of the study show that viewing a film on HIV infection is an effective method of transferring knowledge about HIV to the Serbian military population.

TI Evaluating Liquid and Granular Bacillus thuringiensis var. israelensis Broadcast Applications for Controlling Vectors of Dengue and Chikungunya Viruses in Artificial Containers and Tree Holes SO JOURNAL OF MEDICAL ENTOMOLOGY LA English DT Article DE Aedes aegypti; larval mosquito control; backpack sprayer; ground applications; Stihl SR 450 ID AEDES-AEGYPTI DIPTERA; ASIAN TIGER MOSQUITO; SPRAY APPLICATION; BORNE DISEASES; ALBOPICTUS; CULICIDAE; HABITATS; OVIPOSITION; PREFERENCES; EFFICACY AB The principal vectors of chikungunya and dengue viruses typically oviposit in water-filled artificial and natural containers, including tree holes. Despite the risk these and similar tree hole-inhabiting mosquitoes present to global public health, surprisingly few studies have been conducted to determine an efficient method of applying larvicides specifically to tree holes. The Stihl SR 450, a backpack sprayer commonly utilized during military and civilian vector control operations, may be suitable for controlling larval tree-hole mosquitoes, as it is capable of delivering broadcast applications of granular and liquid dispersible formulations of Bacillus thuringiensis var. israelensis (Bti) to a large area relatively quickly. We compared the application effectiveness of two granular (AllPro Sustain MGB and VectoBac GR) and two liquid (Aquabac XT and VectoBac WDG) formulations of Bti in containers placed on bare ground, placed beneath vegetative cover, and hung 1.5 or 3m above the ground to simulate tree holes. Aedes aegypti (L.) larval mortality and Bti droplet and granule density data (when appropriate) were recorded for each formulation. Overall, granular formulations of Bti resulted in higher mortality rates in the simulated tree-hole habitats, whereas applications of granular and liquid formulations resulted in similar levels of larval mortality in containers placed on the ground in the open and beneath vegetation.

TI Heat generation rate measurement in a Li-ion cell at large C-rates through temperature and heat flux measurements SO JOURNAL OF POWER SOURCES LA English DT Article DE Lithium-ion batteries; Heat generation rate measurement; Heat flux sensor; Thermal conduction; Battery safety ID THERMAL-BEHAVIOR; HIGH-POWER; BATTERIES; ELECTRODES; SYSTEMS; MODEL AB Understanding the rate of heat generation in a Li-ion cell is critical for safety and performance of Li-ion cells and systems. Cell performance, cycle life, and system safety all depend on temperature distribution in the cell, which, in turn, depends on heat generation rate within the cell and on heat removal rate at the cell surface. Despite the existence of a number of theoretical models to predict heat generation rate, there is not much literature on experimental measurement at high C-rates. This paper reports measurement of heat generation rate from a Li-ion cell at high discharge rates, up to 9.6C, using measurements of cell temperature and surface heat flux. As opposed to calorimetry-based approaches, this method can be applied in situ to yield measurements of heat generation rate in laboratory or field use provided that at least one a priori test is performed to measure the temperature gradient within a cell in the same ambient condition. This method is based on simultaneous determination of heat stored and heat lost from the cell through heat flux and temperature measurements. A novel method is established for measurement of the internal temperature of the cell. Heat generation measurements are shown to agree with well-established theoretical models. The effect of actively cooling the cell is briefly discussed. (C) 2015 Elsevier B.V. All rights reserved. C1 [Drake, S. J.; Jain, A.] Univ Texas Arlington, Mech & Aerosp Engn Dept, Arlington, TX USA.

Given the unique stressors experienced by U.S. service members, including lengthy and/or multiple deployments, this study aimed to examine the associations of recent divorce on health and military outcomes among a cohort of U.S. service members. Methods: Millennium Cohort participants from the first enrollment panel, married at baseline (2001-2003), and married or divorced at follow-up (2004-2006), (N = 29,314). Those divorced were compared to those who remained married for mental, behavioral, physical health, and military outcomes using logistic regression models. Results: Compared to those who remained married, recently divorced participants were significantly more likely to screen positive for new-onset posttraumatic stress disorder, depression, smoking initiation, binge drinking, alcohol-related problems, and experience moderate weight gain. However, they were also more likely be in the highest 15th percentile of physical functioning, and be able to deploy within the subsequent 3-year period after divorce. Conclusions: Recent divorce among military members was associated with adverse mental health outcomes and risky behaviors, but was also associated with higher odds of subsequent deployment. Attention should be given to those recently divorced regarding mental health and substance abuse treatment and prevention strategies.

TI Effect of multiple, simultaneous vaccines on polio seroresponse and associated health outcomes SO VACCINE LA English DT Article DE Polio vaccine; IPV; Simultaneous vaccination; Multiple vaccinations; Td; Tdap ID TETANUS-ACELLULAR PERTUSSIS; RANDOMIZED CONTROLLED-TRIAL; T-CELL RESPONSES; GULF-WAR; CONJUGATE VACCINE; CHILDHOOD ASTHMA; ATOPIC DISEASE; RISK-FACTORS; B VACCINE; DIPHTHERIA AB Background: Administration of multiple simultaneous vaccines to infants, children, and military recruits is not uncommon. However, little research exists to examine associated serological and health effects, especially in adults. Method: We retrospectively examined 416 paired serum specimens from U.S. military subjects who had received the inactivated polio vaccine (IPV) alone or in combination with either 1 other vaccine (<3 group) or 4 other vaccines (>4 group). Each of the 2 groups was subdivided into 2 subgroups in which Tdap was present or absent. Results: The >4 group was associated with a higher proportion of polio seroconversions than the <3 group (95% vs. 58%, respectively, p<0.01). Analysis of the <3 subgroup that excluded Tdap vs. the >4 subgroup that excluded Tdap showed no difference between them (p>0.1). However, the >4 subgroup that included Tdap had significantly more seroconversions than either the <3 subgroup that excluded Tdap or the >4 subgroup that excluded Tdap (p<0.01). Overall, at least 98% of subjects were at or above the putative level of seroprotection both pre- and post-vaccination, yet at least 81% of subjects seroconverted. In an analysis of 400 of the subjects in which clinic in- and outpatient encounters were counted over the course of 1 year following vaccinations, there was no significant difference between the 2 groups (p>0.1). Conclusion: A combination of >4 vaccines including IPV appeared to have an immunopotentiation effect on polio seroconversion, and Tdap in particular was a strong candidate for an important role. The dose of IPV we studied in our subjects, who already had a high level of seroprotection, acted as a booster. In addition, there appear to be no negative health consequences from receiving few versus more multiple simultaneous vaccinations. Published by Elsevier Ltd.

TI Longitudinal Investigation of Smoking Initiation and Relapse Among Younger and Older US Military Personnel SO AMERICAN JOURNAL OF PUBLIC HEALTH LA English DT Article ID POSTTRAUMATIC-STRESS-DISORDER; READJUSTMENT RATING-SCALE; DEPARTMENT-OF-DEFENSE; TOBACCO USE; CIGARETTE-SMOKING; UNITED-STATES; PROSPECTIVE COHORT; MILLENNIUM COHORT; SERVICE MEMBERS; BODY-WEIGHT AB Objectives. We examined whether military service, including deployment and combat experience, were related to smoking initiation and relapse. Methods. We included older (panel 1) and younger (panel 2) participants in the Millennium Cohort Study. Never smokers were followed for 3 to 6 years for smoking initiation, and former smokers were followed for relapse. Complementary log-log regression models estimated the relative risk (RR) of initiation and relapse by military exposure while adjusting for demographic, health, and lifestyle factors. Results. Deployment with combat experience predicted higher initiation rate (panel 1: RR = 1.44; 95% confidence interval [CI] = 1.28, 1.62; panel 2: RR = 1.26; 95% CI = 1.04, 1.54) and relapse rate (panel 1 only: RR = 1.48; 95% CI = 1.36, 1.62). Depending on the panel, previous mental health disorders, life stressors, and other military and nonmilitary characteristics independently predicted initiation and relapse. Conclusions. Deployment with combat experience and previous mental disorder may identify military service members in need of intervention to prevent smoking initiation and relapse.

TI Bilocal current densities and mean trajectories in a Young interferometer with two Gaussian slits and two detectors SO JOURNAL OF MATHEMATICAL PHYSICS LA English DT Article ID DELAYED-CHOICE EXPERIMENT AB The recent single-photon double-slit experiment of Steinberg et al., based on a weak measurement method proposed by Wiseman, showed that, by encoding the photon's transverse momentum behind the slits into its polarization state, the momentum profile can subsequently be measured on average, from a difference of the separated fringe intensities for the two circular polarization components. They then integrated the measured average velocity field, to obtain the average trajectories of the photons enroute to the detector array. In this paper, we propose a modification of their experiment, to demonstrate that the average particle velocities and trajectories change when the mode of detection changes. The proposed experiment replaces a single detector by a pair of detectors with a given spacing between them. The pair of detectors is configured so that it is impossible to distinguish which detector received the particle. The pair of detectors is then analogous to the simple pair of slits, in that it is impossible to distinguish which slit the particle passed through. To establish the paradoxical outcome of the modified experiment, the theory and explicit three-dimensional formulas are developed for the bilocal probability and current densities, and for the average velocity field and trajectories as the particle wavefunction propagates in the volume of space behind the Gaussian slits. Examples of these predicted results are plotted. Implementation details of the proposed experiment are discussed. (c) 2015 AIP Publishing LLC. C1 [Withers, L.

A BVA dilution oil was used for the control. Oil-based adulticides were sprayed using a truck-mounted Curtis DynaFog Maxi-Pro 4 ultra-low volume (ULV) sprayer. Malathion (Fyfanon ULV, 96% active ingredient [AI]), resmethrin (Scourge 4 + 12, 4% AI), pyrethrins (ULD BP-300, 3% AI), and BVA Spray 13 (100% refined petroleum distillate) were mixed with Uvitex optical brightener fluorescent dye and applied at 2 speeds on evenings when wind speed was less than 16.1 km/h (10 mph). Collection targets using biodegradable cotton ribbons (I m x 2.5 cm) were later read with a fluorometer to quantify the amount of insecticide deposited on targets set at heights of 15.2, 76.2, and 152.4 cm (6, 30, and 60 in.) and distances of 1.5, 6.1, 15.2, 30.5, 61.0, and 91.4 m (5, 20, 50, 100, 200, and 300 ft). Mean insecticide deposition across all distances was 31% on 76.2-cm targets and 49% on 152.4-cm targets, while 15.2-cm targets typically collected <20% of test spray. Mean ground temperatures were typically within 5 degrees C of air temperatures at 152.4 cm and within 1 to 5 degrees C of air at 15.2 cm or 76.2 cm. Collectively, mean insecticide deposition was 80% at or above 76.2 cm for all insecticides. This finding may explain in part why control of low-flying phlebotomine sand flies with ULV insecticides has been met with less than optimal success by US military forces deployed in the Middle East.

Two battery-powered sprayers, Birchmeier and Hudson, were coriwared with the standard hand-pump SOLO 425 sprayer, which is currently used in pest management operations. Physical characteristics, droplet analysis, and overall ease of use were documented. Multiple dilutions of the insecticide were also evaluated. The results indicated that the Birchmeier sprayer was the preferable machine in terms of its physical characteristics and operator use. There was no significant difference in percent mortality of the test mosquitoes between the sprayers. Multiple dilutions ranging from 1:9 to 1:1050 of the insecticide resulted in greater than 80% mean mortality.

TI Resistance Prediction on Submerged Axisymmetric Bodies Fitted with Turbulent Spot Inducers SO JOURNAL OF SHIP RESEARCH LA English DT Article DE resistance (general); model testing; hydrodynamics (general) ID BOUNDARY-LAYER; TRANSITION AB A method to predict bare hull ship resistance is presented in this article. Hull resistance is assumed to consist of friction drag and residual drag. The friction drag coefficient is represented by an equivalent flat plate coefficient multiplied by a form factor to incorporate effects of body geometry and boundary layer (BL) characteristics on drag. Theories of form factors including the effect of BL transition locations have been successfully derived. Form factors are shown to have a noticeable effect on body drag at high Reynolds numbers (Re) and a significant effect at model Re. Residual drag coefficient is obtained from model tests with application of scaling formulae to relate model scale residual drag coefficient to full scale drag coefficient. To address the issue of laminar flow on models in residual drag measurements, a new device termed a "turbulent spot inducer" is introduced in model tests. Finally, a new scaling formula to relate model scale residual drag coefficient to full scale residual drag coefficient with the flow on body surface partly laminar and partly turbulent is derived. It is shown that a traditional 1+K scaling method used in the marine industry is a special case of the newly derived residual drag scaling formula.

The stepped solver is applicable to hysteretic materials and supports a permanent magnetization. A locally corrected Nystrom discretization of the magnetostatic volume integral equation is used to implement the stepped solver. Characterization of the stepped solver is performed using various magnetic material models which support hysteresis. Solver accuracy is validated using Team Workshop Problem 13, analytic results of a magnetic sphere with hysteresis, and against measured data for a hollow steel pipe.

The basic strategy is to incorporate nanoaluminum in the form of a micrometer scale particle containing a gas-generator, to enable easier processing, and potential benefits resulting from reduced sintering prior to combustion. The mesoparticles were made by electrospray and comprised aluminum nanoparticles (50 nm) and nitrocellulose to form micrometer scale particles. In this study, 80% solids loaded composite propellants (AP/HTPB based) were made with the addition of micrometer sized (2-3 mm) aluminum (10 wt-%), and compared directly to propellants made by directly substituting aluminum mesoparticles for traditional micrometer sized particles. Propellant burning rate was relatively insensitive for mesoparticles containing between 5-15 wt-% nitrocellulose. However, direct comparison between a mesoparticle based propellant, to a propellant containing micrometer scale aluminum particles showed burning rates approximately 35% higher while having a nearly identical burning rate exponent. High speed imaging indicate that propellants using mesoparticles have less agglomeration of particles on the propellant surface.

TI Neuraminidase inhibitor therapy in a military population SO JOURNAL OF CLINICAL VIROLOGY LA English DT Article DE Influenza; Neuraminidase inhibitors; Severity; Prescription; Antivirals ID VIRUS-INFECTION; UNITED-STATES; INFLUENZA; OSELTAMIVIR; ILLNESS; ONSET AB Background: Although neuraminidase inhibitors (NI) are the mainstay of treatment for influenza infection, prescribing practice for these agents is not well described. Additionally, benefit is contested. Objectives: We examined provider prescriptions of NI during the 2009 pandemic and post-pandemic periods. We also evaluated the effectiveness of NI in reducing severity of influenza infection. Study design: Data on NI prescription and severity of influenza infection were compiled in healthy pediatric and adult beneficiaries enrolled in a prospective study of influenza like illness conducted at five military medical centers over five years. Subjects underwent nasal swabs to determine viral etiology of their infection. Demographic, medication and severity data were collected. Subjects with positive influenza were included. Results: Two hundred sixty three subjects were influenza positive [38% [H1N1] pdm09, 38.4% H3N2, and 20.5% B); 23.9% were treated with NI. NI were initiated within 48 h in 63% of treated subjects. Although NI use increased over the five years of the study, early use declined. Most measures for severity of illness were not significantly reduced with NI; adults treated within 48 h had only a modest reduction in duration and severity of some of their symptoms. Conclusions: NI use in our population is increasing, but early use is not. NI use resulted in no reduction in complications of illness. Resolution of symptoms and reduction in severity of some symptoms were slightly better in adults who were treated early. These modest benefits do not support routine treatment with NI in otherwise healthy individuals with influenza. (C) 2015 Elsevier B.V. All rights reserved.

TI Nanocarbon-copper thin film as transparent electrode SO APPLIED PHYSICS LETTERS LA English DT Article ID NANOWIRE NETWORKS; METAL; NANOFIBERS; DEPOSITION; SURFACE AB Researchers seeking to enhance the properties of metals have long pursued incorporating carbon in the metallic host lattice in order to combine the strongly bonded electrons in the metal lattice that yield high ampacity and the free electrons available in carbon nanostructures that give rise to high conductivity. The incorporation of carbon nanostructures into the copper lattice has the potential to improve the current density of copper to meet the ever-increasing demands of nanoelectronic devices. We report on the structure and properties of carbon incorporated in concentrations up to 5 wt. % (similar to 22 at. %) into the crystal structure of copper. Carbon nanoparticles of 5 nm-200 nm in diameter in an interconnecting carbon matrix are formed within the bulk Cu samples. The carbon does not phase separate after subsequent melting and re-solidification despite the absence of a predicted solid solution at such concentrations in the C-Cu binary phase diagram. This material, so-called, Cu covetic, makes deposition of Cu films containing carbon with similar microstructure to the metal possible. Copper covetic films exhibit greater transparency, higher conductivity, and resistance to oxidation than pure copper films of the same thickness, making them a suitable choice for transparent conductors.

TI Rhombohedral magnetostriction in dilute iron (Co) alloys SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID CONSTANTS AB Iron is a well-utilized material in structural and magnetic applications. This does not mean, however, that it is well understood, especially in the field of magnetostriction. In particular, the rhombohedral magnetostriction of iron, lambda(111), is anomalous in two respects: it is negative in sign, in disagreement with the prediction of first principles theory, and its magnitude decreases with increasing temperature much too rapidly to be explained by a power law dependence on magnetization. These behaviors could arise from the location of the Fermi level, which leaves a small region of the majority 3d t(2g) states unfilled, possibly favoring small internal displacements that split these states. If this view is correct, adding small amounts of Co to Fe fills some of these states, and the value of lambda(111) should increase toward a positive value, as predicted for perfect bcc Fe. We have measured the magnetostriction coefficients (lambda(111) and lambda(100)) of pure Fe, Fe97Co3, and Fe94Co6 single crystals from 77K to 450 K. Resonant ultrasound spectroscopy has been used to check for anomalies in the associated elastic constants, c(44) and c'. The additional electrons provided by the cobalt atoms indeed produced positive contributions to both magnetostriction constants, lambda(111) and lambda(100), exhibiting an increase of 2.8 x 10(-6) per at.% Co for lambda(111) and 3.8 x 10(-6) per at.% Co for lambda(100).

TI Effects of Zn additions to highly magnetoelastic FeGa alloys SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID GA; MAGNETOSTRICTION AB Fe1-xMx (M = Ga, Ge, Si, Al, Mo and x similar to 0.18) alloys offer an extraordinary combination of magnetoelasticity and mechanical properties. They are rare-earth-free, can be processed using conventional deformation techniques, have high magnetic permeability, low hysteresis, and low magnetic saturation fields, making them attractive for device applications such as actuators and energy harvesters. Starting with Fe-Ga as a reference and using a rigid-band-filling argument, Zhang et al. predicted that lowering the Fermi level by reducing the total number of electrons could enhance magnetoelasticity. To provide a direct experimental validation for Zhang's hypothesis, elemental additions with lower-than-Ga valence are needed. Of the possible candidates, only Be and Zn have sufficient solubility. Single crystals of bcc Fe-Ga-Zn have been grown with up to 4.6 at.% Zn in a Bridgman furnace under elevated pressure (15 bars) in order to overcome the high vapor pressure of Zn and obtain homogeneous crystals. Single-crystal measurements of magnetostriction and elastic constants allow for the direct comparison of the magnetoelastic coupling constants of Fe-Ga-Zn with those of other magnetoelastic alloys in its class. The partial substitution of Ga with Zn yields values for the magnetoelastic coupling factor, -b(1), comparable to those of the binary Fe-Ga alloy. (C) 2015 AIP Publishing LLC.

Methods: Using data from 28,866 Millennium Cohort Study participants (n = 3782 of whom were discharged during the years between assessments), we 1) investigated changes in meeting federal PA guidelines for moderate-to-vigorous activity (MVPA) following military discharge and 2) determined predictors of meeting these guidelines after discharge. Results: MVPA declined more in those who were discharged than in those who were not (-17.8 percentage points vs. 2.7 percentage points), with greater declines in former active-duty personnel, those who had deployed with combat exposures, had 14 to 25 years of service, and had been discharged more recently (>2 years prior). In those who were discharged, being normal or overweight (vs. obese), and a nonsmoker or former smoker (vs. current smoker) were positively associated with meeting MVPA Guidelines at follow-up, while meeting MVPA Guidelines at baseline and depression were inversely associated. Conclusions: Reductions in MVPA were substantial and unexpected. Increased understanding of transitional periods that may benefit from interventions to mitigate declines in PA will help prevent excess weight gain and physical inactivity-associated health consequences.

The demands for information from these visits require interoperable data exchange standards. While multiple data exchange specifications are in use, none have undergone rigorous standards review. This paper describes the creation and balloting of the Health Level Seven (HL7) Data Elements for Emergency Department Systems (DEEDS). Methods Existing data exchange specifications were collected and organized into categories reflecting the workflow of emergency care. The concepts were then mapped to existing standards for vocabulary, data types, and the HL7 information model. The HL7 community then processed the specification through the normal balloting process addressing all comments and concerns. The resulting specification was then submitted for publication as an HL7 informational standard. Results The resulting specification contains 525 concepts related to emergency care required for operations and reporting to external agencies. An additional 200 of the most commonly ordered laboratory tests were included. Each concept was given a unique identifier and mapped to Logical Observation Identifiers, Names, and Codes (LOINC). HL7 standard data types were applied. Discussion The HL7 DEEDS specification represents the first set of common ED related data elements to undergo rigorous standards development. The availability of this standard will contribute to improved interoperability of emergency care data.

TI A Descriptive Study of the US Marine Corps Fitness Tests (2000-2012) SO MILITARY MEDICINE LA English DT Article ID PHYSICAL-FITNESS; INFANTRY SOLDIERS; INJURIES AB This article describes the performance of active duty U.S. Marines on the Physical Fitness Test (PFT) and Combat Fitness Test (CFT) during calendar years 2000 through 2012. Our study sample included PFT composite scores (n = 543,185), PFT and CFT composite scores (n = 160,936), and PFT and CFT event scores (n = 135,926 and n = 201,953, respectively). In general, all Marines performed very well on each fitness test, with overall annual improvements. Interestingly, the majority of female Marines passed the minimum male standard on the CFT. Further studies will evaluate the relationship of fitness test performance and injury.

TI A Performance Prediction Model for Low-Speed Centrifugal Fans SO JOURNAL OF FLUIDS ENGINEERING-TRANSACTIONS OF THE ASME LA English DT Article ID COMPRESSORS AB A generalized model for mapping the trend of the performance characteristics of a double-discharge centrifugal fan is developed based on the work by Casey and Robinson (C&R), which formulated compressor performance maps for tip-speed Mach numbers ranging from 0.4 to 2 using test data obtained from turbochargers with vaneless diffusers. The current paper focuses on low-speed applications for Mach number below 0.4. The C&R model uses four nondimensional parameters at the design condition including the flow coefficient, the work input coefficient, the tip-speed Mach number, and the polytropic efficiency, in developing a prediction model that requires limited geometrical knowledge of the centrifugal turbomachine. For the low-speed fan case, the C&R formulas are further extended to a low-speed, incompressible analysis. The effort described in this paper begins by comparing generalized results using efficiency data obtained from a series of fan measurements to that using the C&R model. For the efficiency map, the C&R model is found to heavily depend on the ratio of the flow coefficient at peak efficiency to that at the choke flow condition. Since choke flow is generally not applicable in the low-speed centrifugal fan operational environment, an alternate, but accurate estimation method based on fan free delivery derived from the fan test data is presented. Using this new estimation procedure, the modified C&R model predicts reasonably well using the double-discharge centrifugal fan data for high-flow coefficients, but fails to correlate with the data for low-flow coefficients. To address this undesirable characteristic, additional modifications to the C&R model are also presented for the fan application at low flow conditions. A Reynolds number correction is implemented in the work input prediction of the C&R model to account for low-speed test conditions. The new model provides reasonable prediction with the current fan data in both work input and pressure rise coefficients. Along with the developments for the efficiency and work input coefficient maps, the use of fan shut-off and free delivery conditions are also discussed for low-speed applications.

CA IDCRP TravMil Study Grp TI Epidemiology and Self-Treatment of Travelers' Diarrhea in a Large, Prospective Cohort of Department of Defense Beneficiaries SO JOURNAL OF TRAVEL MEDICINE LA English DT Article ID IRRITABLE-BOWEL-SYNDROME; RESOURCE-LIMITED DESTINATIONS; DEVELOPING-COUNTRIES; EUROPEAN TRAVELERS; UNITED-STATES; LOPERAMIDE; SYMPTOMS; MEXICO; RISK; AZITHROMYCIN AB BackgroundInfectious diarrhea is a common problem among travelers. Expert guidelines recommend the prompt use of antibiotics for self-treatment of moderate or severe travelers' diarrhea (TD). There is limited data on whether travelers follow these self-treatment guidelines. We evaluated the risk factors associated with TD, the use of TD self-treatment, and the risk of irritable bowel syndrome (IBS) during travel. MethodsDepartment of Defense beneficiaries traveling outside the United States for 6.5months were enrolled in a prospective cohort study. Participants received pre- and post-travel surveys, and could opt into a travel illness diary and follow-up surveys for symptoms of IBS.Standard definitions were used to assess for TD and IBS. Suboptimal self-treatment was defined as the use of antibiotics (with or without antidiarrheal agents) for mild TD, or the use of antidiarrheals alone or no self-treatment in cases of moderate or severe TD. ResultsTwenty-four percent of participants (270/1,120) met the criteria for TD. The highest incidence was recorded in Africa [8.6 cases/100 person-weeks, 95% confidence interval (CI): 6.7-10.5]. Two hundred and twelve participants with TD provided information regarding severity and self-treatment: 89 (42%) had mild TD and 123 (58%) had moderate or severe TD. Moderate or severe TD was independently associated with suboptimal self-treatment [OR 10.4 (95% CI: 4.92-22.0)]. Time to last unformed stool did not differ between optimal and suboptimal self-treatment. IBS occurred in 4.5% (7/154) of TD cases and in 3.1% (16/516) of cases without TD (p=0.39). Among TD cases, a lower incidence of IBS was noted in participants who took antibiotics [4.8% (5/105) vs 2.2% (1/46)] in those who did not, but the difference did not reach statistical significance (p=0.60). ConclusionsOur results suggest the underutilization of antibiotics in travelers with moderate or severe TD. Further studies are needed to systematically evaluate pre-travel instruction and traveler adherence to self-treatment guidelines, and the impact of suboptimal self-treatment on outcomes.

Experiments and non-destructive evaluation (NDE) have illustrated good correlations between impact energy and foreign object damage (FOD) assessed using electrical resistivity (ER), acoustic emission (AE), and microscopy. A progressive failure dynamic analysis (PFDA) method is explored in understanding and predicting the damage states, ER, and residual strength after impact of CMCs. To accurately correlate the damage state with ER, the PFDA tool has been improved to incorporate the physical damage mechanisms in CMCs, which are matrix microcrack density due to both longitudinal and transverse tensile loads and the fiber breakage due to probabilistic fiber strength distribution. The predicted damage states and ER are correlated with the measurement of FOD and validated with tension after impact tests using high temperature ER. The PFDA tool has demonstrated a great potential for CMCs' FOD and residual strength predictions. C1 [Abdi, Frank; Xue, Yibin] AlphaSTAR Corp, Long Beach, CA 90804 USA.

TI A bilocal picture of quantum mechanics SO JOURNAL OF PHYSICS A-MATHEMATICAL AND THEORETICAL LA English DT Article DE propagators; bilocal events; probability density; current density; Born's rule; probabilistic Schrodinger equation AB A new, bilocal picture of quantum mechanics is developed. We show that Born's rule supports a virtual probability for a particle to arrive, as a wave, at any two locations (but no more). We discuss two ways to implement twin detectors suitable for detecting bilocal arrivals. The bilocal picture sheds light on currents in quantum mechanics. We find there are two types of bilocal current density, whose polar form and related mean velocities are given. In the bilocal context, the definitions of both current types simplify. In the unilocal case, the two types become the usual current and a fluctuation current. Their respective mean velocity fields are the usual de Broglie-Madelung-Bohm velocity and the imaginary (osmotic) velocity. We obtain a new, probabilistic Schrodinger equation for the bilocal probability by itself, solve the example of a free particle, develop the dyadic stationary states, and find that the von Neumann equation for time-varying density of states follows directly from the new equation. We also show how to include the electromagnetic potentials in this probabilistic Schrodinger equation. C1 [Withers, L.

Standardized methods of searching and data abstraction were used.Results:Ninety-two studies met the eligibility criteria: 24 articles related to adherence counseling and support, 13 on risk reduction education and condom provision, 19 on partner HIV testing and counseling, 14 on provision of family planning services, and 22 on assessment and treatment of other sexually transmitted infections. Findings indicate good evidence that adherence counseling and sexually transmitted infection treatment can have a high impact on morbidity, whereas risk reduction education, partner HIV testing and counseling, and family planning counseling can prevent transmission of HIV. More limited evidence was found to support the impact of these interventions on retention in care and quality of life. Most studies did not report cost information, making it difficult to draw conclusions about the cost-effectiveness of these interventions.Conclusions:This evidence suggests that these prevention interventions, if brought to sufficient scale and coverage, can help support and optimize the impact of core treatment and prevention interventions in RLS. Further operational research with more rigorous study designs, and ideally with biomarkers and costing information, is needed to determine the best model for providing these interventions in RLS.

Survival-time estimates should be grounded in empirical observations. Unfortunately, research in this domain has been limited to a single paper describing the development of died-of-wounds curves for combat casualties with life-threatening injuries. The curves developed from that research were based on a small dataset (n = 160, with 26 deaths and 134 survivors) of forward surgical (Role II) casualties and subject matter experts' judgments. This paper reports the first empirically based time-to-death curves for combat casualties based on a large sample. The results indicate that survival time varied across roles of care at which casualties died but was at most weakly associated with injury severity. Time-to-death curves were, therefore, developed for the overall study population of valid times to death and for Role I, Role II and Role III care. The log-logistic probability distribution provided the best representation of the survival times for the overall study population, while the log-normal distribution was the best choice for Role I, Role II and Role III care. The proposed time-to-death curves should refine the survival-time estimates used in combat medical logistics planning.

Methods Associations of latitude and UVB irradiance with age-standardized incidence rates of multiple myeloma were analyzed for 175 countries while controlling for sex-specific obesity prevalence, cigarette consumption, and alcohol consumption using multiple linear regression. Results Incidence rates of multiple myeloma were greater at higher latitudes (R-2 for latitude for males = 0.31, p < 0.0001; females R-2=0.27, p < 0.0001). In regression models for males (R-2=0.62, p < 0.0001) and females (R-2=0.51, p < 0.0001), UVB irradiance was independently inversely associated with incidence rates. Conclusions Age-adjusted incidence rates of multiple myeloma were higher in countries with lower solar UVB irradiance.

MethodsLongitudinal analysis techniques were used to examine data (2001-2008) from Millennium Cohort Study participants, consisting of U.S. service members and veterans. Using the PTSD Checklist-Civilian Version, PTSD was assessed as none, resolved, new onset, or persistent. Subsequent weight change was assessed as stable (loss or gain), >3% weight loss, >3% but <10% weight gain, and 10% weight gain. ResultsOf the 38,352 participants, 2391 (6.2%) had PTSD (838 resolved, 1024 new onset, and 529 persistent), and 11% of participants subsequently had 10% weight gain. In multivariable models, PTSD was associated with higher odds of 10% weight gain (new onset OR: 1.44 [95% CI: 1.20-1.73]; persistent OR: 1.51 [CI: 1.17-1.96]; resolved OR: 1.30 [CI: 1.05-1.60]) compared with those without PTSD. New-onset and persistent PTSD were also associated with higher odds of >3% weight loss (OR: 1.41 [CI: 1.17-1.71]; OR: 1.42 [CI: 1.09-1.86], respectively). ConclusionsPTSD is independently associated with a higher risk of weight gain and loss, the former of which leads to a higher prevalence of overweight and obesity and a higher risk of comorbidities associated with excessive body adiposity.

TI Three-Dimensional SGBEM-FEM Alternating Method for Analyzing Fatigue-Crack Growth in and the Life of Attachment Lugs SO JOURNAL OF ENGINEERING MECHANICS LA English DT Article ID SURFACE CRACKS; FRACTURE-MECHANICS; SINGULAR TRACTION; ROUND BARS; ELEMENTS; ELASTICITY; INTEGRALS; TENSION; HOLE; BIE AB In the present paper, stress intensity factor (SIF) analyses and fatigue-crack-growth simulations of corner cracks emanating from loaded pinholes of attachment lugs in structural assemblies are carried out for different load cases. A three-dimensional (3D) symmetric Galerkin boundary-element method (SGBEM) and FEM alternating method is developed to analyze the nonplanar growth of these surface cracks under general fatigue. The 3D SGBEM-FEM alternating method involves two very simple and coarse meshes that are independent of each other: (1) a very coarse FEM mesh to analyze the uncracked lug, and (2) a very coarse SGBEM mesh to model only the growing crack surface. By using the SGBEM-FEM alternating method, the nonplanar growth of cracks in 3D (surfaces of discontinuity) up to the failure of structures are efficiently simulated, and accurate estimations of fatigue lives are made. The accuracy and reliability of the SGBEM-FEM alternating method are verified by comparing them to other FEM solutions, as well as experimental data for fatigue-crack growth available in the open literature. The SIF calculations, crack surface evolutions, and fatigue-life estimations are all in good agreement with other detailed FEM solutions and experimental observations. It is noted that for fracture and fatigue analyses of complex 3D structures such as attachment lugs, a pure FEM requires several hundreds of thousands or even millions of elements, whereas the present 3D SGBEM-FEM alternating method requires only up to 1,000 FEM elements and similar to 100 SGBEM elements. It thus demonstrates that the present SGBEM-FEM alternating method, among the many Schwartz-Neumann-type alternating methods developed in the past 20-30 years are suitable for analyzing fracture and fatigue-crack propagation in complex 3D structures in a very computationally efficient manner, as well as with very low human labor costs.

A batch of as-received desert sand was melted into calcium magnesium aluminosilicate (CMAS) glass at similar to 1500 degrees C. From inductively coupled plasma-atomic emission spectrometry, chemical composition of the CMAS glass was analyzed to be 27.8CaO-4MgO-5Al(2)O(3)-61.6SiO(2)-0.6Fe(2)O(3)-1K(2)O (mole %). Various physical, thermal, and mechanical properties of the glass have been evaluated. Bulk density of CMAS glass was 2.69 g/cm(3), Young's modulus 92 GPa, Shear modulus 36 GPa, Poisson's ratio 0.28, dilatometric glass transition temperature (;) 706 degrees C, softening point (T-d) 764 degrees C, Vickers microhardness 6.3 +/- 0.4 GPa, indentation fracture toughness 0.75 +/- 0.15 MPa.m(1/2), and coefficient of thermal expansion (CTE) 9.8 x 10(-6)/degrees C in the temperature range 25 to 700 degrees C. Temperature dependence of viscosity has also been estimated from various reference points of the CMAS glass using the Vogel-FulcherTamman (VFT) equation as well as from the glass composition. The glass remained amorphous after heat treating at 850 degrees C for 10 h but crystallized into CaSiO3 and Ca2Mg0.5AlSi1.5O7 phases at 900 degrees C or higher temperatures. Crystallization kinetics of the CMAS glass has also been investigated by differential thermal analysis (DTA). Published by Elsevier Ltd and Techna Group S.r.l.

TI Seroprotective Antibodies to 2011 Variant Influenza A(H3N2v) and Seasonal Influenza A(H3N2) among Three Age Groups of US Department of Defense Service Members SO PLOS ONE LA English DT Article ID LONG-TERM IMMUNOGENICITY; UNITED-STATES; HUMAN INFECTIONS; IMMUNE-RESPONSE; H1N1 2009; VACCINE; VIRUS; ADULTS; EFFICACY; H3N2V AB Background In 2011, a new variant of influenza A(H3N2) emerged that contained a recombination of genes from swine H3N2 viruses and the matrix (M) gene of influenza A(H1N1)pdm09 virus. New combinations and variants of pre-existing influenza viruses are worrisome if there is low or nonexistent immunity in a population, which increases chances for an outbreak or pandemic. Methods Sera collected in 2011 were obtained from US Department of Defense service members in three age groups: 19-21 years, 32-33 years, and 47-48 years. Pre- and post-vaccination samples were available for the youngest age group, and postvaccination samples for the two older groups. Specimens were tested using microneutralization assays for antibody titers against H3N2v (A/Indiana/10/2011) and seasonal H3N2 virus (A/Perth/16/2009). Results The youngest age group had significantly (p<0.05) higher geometric mean titers for H3N2v with 165 (95% confidence interval [CI]: 105-225) compared with the two older groups, aged 32-33 and 47-48 years, who had geometric mean titers of 68 (95% CI: 55-82) and 46 (95% CI: 24-65), respectively. Similarly, the youngest age group also had the highest geometric mean titers for seasonal H3N2. In the youngest age group, the proportion of patients who seroconverted after vaccination was 12% for H3N2v and 27% for seasonal H3N2. Discussion Our results were similar to previous studies that found highest seroprotection among young adults and decreasing titers among older adults. The proportion of 19- to 21-year-olds who seroconverted after seasonal vaccination was low and similar to previous findings. Improving our understanding of H3N2v immunity among different age groups in the United States can help inform vaccination plans if H3N2v becomes more transmissible in the future.

The nominal Mach and Reynolds numbers are 1.3 and 1 million, respectively. No-control, symmetrically controlled, and under-expanded jets are also simulated for comparison purposes. Parametric variation of actuation frequency and duty cycle indicate that asymmetric control can alter the trajectory, and, within the confines of the parameters investigated, the optimal forcing scheme was found to correspond to the jet's column-mode frequency and a duty cycle of approximately 60%. Increasing frequency and duty cycle beyond these values have a detrimental effect on control, which is consistent with experimental findings. Asymmetric actuation resulted in significant mixing enhancement on the actuated side, as evidenced by the increased growth rate of the non-dimensional momentum thickness. The effectiveness of control is reduced for under-expanded jet conditions. C1 [Gonzalez, D. R.] Naval Surface Warfare Ctr, Warhead & Prop Technol Branch, Indian Head, MD 20640 USA. [Gaitonde, D.

TI Epidemiologic, clinical, and virologic characteristics of human rhinovirus infection among otherwise healthy children and adults Rhinovirus among adults and children SO JOURNAL OF CLINICAL VIROLOGY LA English DT Article DE Rhinovirus; HRV genotypes; Viral shedding; Military ID RESPIRATORY-TRACT INFECTION; A VIRUS-INFECTION; HOSPITALIZED CHILDREN; PHYLOGENETIC ANALYSIS; MOLECULAR-FEATURES; DIVERSITY; RESPONSES; SEVERITY; SEQUENCE; STRAINS AB Background: human rhinovirus (HRV) is a major cause of influenza-like illness (ILI) in adults and children. Differences in disease severity by HRV species have been described among hospitalized patients with underlying illness. Less is known about the clinical and virologic characteristics of HRV infection among otherwise healthy populations, particularly adults. Objectives: to characterize molecular epidemiology of HRV and association between HRV species and clinical presentation and viral shedding. Study design: observational, prospective, facility-based study of ILI was conducted from February 2010 to April 2012. Collection of nasopharyngeal specimens, patient symptoms, and clinical information occurred on days 0, 3, 7, and 28. Patients recorded symptom severity daily for the first 7 days of illness in a symptom diary. HRV was identified by RT-PCR and genotyped for species determination. Cases who were co-infected with other viral respiratory pathogens were excluded from the analysis. We evaluated the associations between HRV species, clinical severity, and patterns of viral shedding. Results: eighty-four HRV cases were identified and their isolates genotyped. Of these, 62 (74%) were > 18 years. Fifty-four were HRV-A, 11HRV-B, and 19HRV-C. HRV-C infection was more common among children than adults (59% vs. 10%, P < 0.001). Among adults, HRV-A was associated with higher severity of upper respiratory symptoms compared to HRV-B (P = 0.02), but no such association was found in children. In addition, adults shed HRV-A significantly longer than HRV-C (P trend = 0.01). Conclusions: among otherwise healthy adults with HRV infection, we observed species-specific differences in respiratory symptom severity and duration of viral shedding. (C) 2015 Elsevier B.V.

Infection intensity in workers averaged 8.2 x 10(7) spores/bee. The main site of infection was adipose tissue where hypertrophy of adipocytes resulted in cyst-like body formation. Mature spores were ovoid and monomorphic. They measured 4.00 mu m x 2.37 mu m (fresh) or 3.98 mu m x 1.88 mu m (fixed). All stages were diplokariotic and developed in direct contact with host cytoplasm. Isofilar polar filament was arranged in 16 coils in one or, posteriorly, two layers. Coiling angle was variable, between perpendicular and almost parallel to major spore axis. Late meronts and sporogonial stages were surrounded by vesicles of approximately 60 nm in diameter. Based on both new and already designed primers, a 1827 bp (SSUrRNA, ITS, LSUrRNA) sequence was obtained. Data analyses suggest that this microsporidium is a new species of the genus Tubulinosema. The name Tubulinosema pampeana sp. n. is proposed. (C) 2015 Elsevier Inc. All rights reserved.

We measured novelty seeking to test whether side of onset of Parkinson disease predicted patients' risk for impulsivity. Methods: We evaluated 38 patients with Parkinson disease (19 right onset, 19 left onset) and 44 community-dwelling neuro-typical controls. All participants completed demographic and mood measures and the Temperament and Character Inventory personality questionnaire. The right-and left-onset groups were nearly the same in background and clinical variables, including use of dopamine agonists. Results: The patients with right-onset disease exhibited significantly higher levels of novelty seeking than the patients with left-onset disease. Conclusions: Our results suggest that patients with right-onset Parkinson disease who are taking dopamine agonists and who exhibit high novelty seeking are at greater risk for developing impulse control disorders than are patients with left onset who are also taking dopamine agonists.

In the direct simulation approach, rudders, stern planes, and propellers are gridded and treated as moving objects using dynamic overset technology. The second approach couples the overset computational fluid dynamics (CFD) solver and a potential flow propeller code, with both codes exchanging velocities at the propeller plane and wake, body forces, and propeller forces and moments, whereas rudders and stern planes are still explicitly resolved. It is shown that during the maneuvers, the range of advance coefficients does not deviate much from the design point, making a coupled approach a valid choice for standard maneuvering simulations. By allowing time steps about an order of magnitude larger than for the direct simulation approach, the coupled approach can run about five times faster. The drawback is a loss of resolution in the wake as the direct propeller simulation can resolve blade vortical structures. Open water propeller curves were simulated with both the direct propeller approach and the coupled approach, showing that the coupled approach can match the direct approach performance curves for a wide range of advance coefficients. Simulations of a horizontal overshoot maneuver at two approach speeds were performed, as well as vertical overshoot and controlled turn maneuvers at high speed. Results show that both CFD approaches can reproduce the experimental results for all parameters, with errors typically within 10%. C1 [Martin, J.

Efficacy evaluations were determined through adult population collections and excised leaf bioassays. Trapping results showed a mean reduction of 77% in mosquito populations in the treated area for 5 sampling events up to 4 wk posttreatment. Leaf bioassays revealed an average mortality of 80% at 2.7 m and 51% at 5.5 m against laboratory-reared Aedes aegypti for 5 posttreatment samples. Leaves collected from the treated areas caused higher mortality at distances closer to the sprayer, though the distance and coverage of bifenthrin application was effective up to 5 m.

These injuries may affect the natural ability to stabilize the head while walking. A simple method of utilizing motion capture equipment to measure head movement while walking was used to assess improvements in head stabilization of persons undergoing computerized vestibular physical therapy and virtual reality training for treatment of their vestibular problems. Movement data from the head and sacrum during gait were obtained over several visits and then analyzed to determine improved oscillatory head movement relative to the sacrum. The data suggest that, over time with treatment, head stabilization improves and moves toward a pattern similar to that of a healthy control population. This simple analysis of measuring head stability could be transferred to smaller, portable systems that are easily utilized to measure head stability during gait for use in gait assessment and physical therapy training.

This study measured improvements in gait speed and weight shift for subjects receiving vestibular physical therapy using a Computer-Assisted Rehabilitation Environment (CAREN). A 6-session CAREN, 6-session traditional vestibular therapy group was compared with a 12-session CAREN only (0 traditional sessions) therapy group. These two groups were compared to each other and with data from healthy controls performing similar tasks on the CAREN. Those participating in 12 CAREN sessions had greater improvements in gait speed (p = 0.014) and weight shift scores (p < 0.001) and demonstrated similar values achieved by a healthy control population.

TI Changes in Combat Task Performance Under Increasing Loads in Active Duty Marines SO MILITARY MEDICINE LA English DT Article; Proceedings Paper CT Military Health Systems Research Symposium (MHSRS) CY AUG 13-16, 2012 CL Fort Lauderdale, FL ID BODY ARMOR; FEMALE HIKERS; BACKPACK LOAD; CARRIAGE; PAIN; FIREFIGHTERS; EQUIPMENT; RESPONSES; SOLDIERS; WORK AB U.S. Marines perform mission tasks under heavy loads which may compromise performance of combat tasks. However, data supporting this performance decrement are limited. Purpose: The aim of this study was to determine the effects of load on performance of combat-related tasks. Methods: Subjects (N = 18) ran a modified Maneuver Under Fire ([MANUF], 300 yards [yd] total: two 25-yd sprints, 25-yd crawl, 75-yd casualty drag, 150-yd ammunition can carry, and grenade toss) portion of the U.S. Marine Corps Combat Fitness Test under 4 trial conditions: neat (no load), 15%, 30%, and 45% of body weight, with a shooting task pre-and post-trial. Results: There was a significant increase in total time to completion as a function of load (p < 0.0001) with a relationship between load and time (r = 0.592, p < 0.0001). Pre- to post-MANUF shot accuracy (p = 0.005) and precision (p < 0.0001) was reduced. Conclusion: Short aerobic performance is significantly impacted by increasing loads. Marksmanship is compromised as a function of fatigue and load. These data suggest that loads of 45% body weight increase time to cover distance and reduce the ability to precisely hit a target.

We performed a retrospective chart review of the Expeditionary Medical Encounter Database from 2004 to 2010. 1,345 military personnel with combat-related maxillofacial injuries were identified. Injury severity was quantified with the Abbreviated Injury Scale and Injury Severity Score. Service members with maxillofacial injury and severe combat trauma (Injury Severity Score 3 16) were included. The distribution of facial fractures, types, and outcomes of surgical repairs, incidence of traumatic brain injury, concomitant head and neck injuries, burn rate/severity, and rates of Acinetobacter baumannii colonization and surgical site infection were analyzed. The prevalence of maxillofacial injury in the Expeditionary Medical Encounter Database was 22.7%. The most common mechanism of injury was improvised explosive device (65.7%). Midface trauma and facial burns were common. Approximately 64% of the study sample sustained traumatic brain injury. Overall, 45.6% (109/239) had at least one facial bone fracture. Of those with facial fractures, 64.2% (n = 70) underwent surgical repair. None of the service members who underwent in-theater facial fracture repair developed A. baumannii facial wound infection or implant extrusion.

Near-term benefits of cessation may motivate active young people to quit or avoid smoking. Military basic training includes mandatory tobacco cessation, as well as uniform physical conditioning regimes, creating an opportunity to evaluate changes in physical performance metrics in direct relation to smoking cessation. These analyses included data from all men who completed Marine Corps recruit training in San Diego, California, between 2002 and 2006. Recruits reported tobacco use and other health metrics on a pretraining survey. Initial and final aerobic run-times were recorded over the 3-month training period. Multivariable linear regression analyses assessed changes in run-speed relative to pre-enlistment smoking history. Among 52,419 young men included in analyses, 13,248 (25.3%) reported smoking before enlistment. Average run-speeds improved among all groups of recruits; however, improvement was greater among prior smokers compared to recruits with no history of smoking (average increase of 0.31 vs. 0.21 miles per hour) and statistically significant in multivariate analyses. Smoking cessation in this cohort of young men resulted in improved physical aerobic performance, independent of other behavioral health characteristics. These data may be useful in promoting and motivating smoking cessation among young, active adults. C1 [Feinberg, Jeffrey H.; Ryan, Margaret A.

TI A direct search approach to optimization for nonlinear model predictive control SO OPTIMAL CONTROL APPLICATIONS & METHODS LA English DT Article DE model predictive control; real-time optimization ID RECEDING HORIZON CONTROL; CONSTRAINED OPTIMIZATION; SYSTEMS; BLACK AB Nonlinear model predictive control (NMPC) depends on performing a constrained nonlinear optimization, based on predictions of future system behavior, during a sampling interval to determine the control action to be applied to the system during the next time step. The difficulty in designing an optimization procedure to solve a constrained NMPC problem is due to the finite time horizon to which the predictive model is evaluated, the state and control actuator constraints, and sampling interval length. The resulting objective function, which is to be optimized is typically not differentiable. Although there are many commercial, shareware, and open-source optimization packages available that can perform a nonlinear constrained optimization for most cases, there are NMPC implementations requiring embedded code or that must meet stringent timing requirements that preclude the use of off-the-shelf packages. In cases where the predictive model is known, such as aerodynamic or hydrodynamic systems, a direct-search optimization algorithm can perform well enough in a real-time environment. Direct search algorithms are simple to implement and can be made more efficient by applying differential geometric techniques to the search methodology. The typical smoothness of the equations of motion for vehicular systems allows the objective function's stationarities to be handled in a straight-forward way.

However, the prevalence and correlates of relapse are unknown. We sought to identify socio-demographic, military, behavioral, and health characteristics associated with relapse among current and former military members with remittent problem drinking. Methods: Participants in the longitudinal Millennium Cohort Study who reported problem drinking at baseline (2001-2003) and were remittent at first follow-up (2004-2006) were included (n = 6909). Logistic regression models identified demographic, military service, behavioral, and health characteristics that predicted relapse (report of >= 1 past-year alcohol-related problem on the validated Patient Health Questionnaire) at the second follow-up (2007-2008). Results: Sixteen percent of those with remittent problem drinking relapsed. Reserve/National Guard members compared with active-duty members (odds ratio [OR] = 1.71,95% confidence interval [CI]: 1.45-2.01), members separated from the military during follow-up (OR= 1.46, 95% CI: 1.16-1.83), and deployers who reported combat exposure (OR = 1.32, 95% CI: 1.07-1.62, relative to non-deployers) were significantly more likely to relapse. Those with multiple deployments were significantly less likely to relapse (OR= 0.73,95% CI: 0.58-0.92). Behavioral factors and mental health conditions also predicted relapse. Conclusion: Relapse was common and associated with military and non-military factors. Targeted intervention to prevent relapse may be indicated for military personnel in particular subgroups, such as Reservists, veterans, and those who deploy with combat exposure.

This work was an extension and companion of the previous work conducted in dynamic fatigue. Four different applied stresses ranging from 120 to 170 MPa was incorporated with a total of 20-23 test specimens used at each of four applied stresses. The slow crack growth (SCG) parameters n and D were found to be n = 19 and D = 45 with a coefficient of correlation of r(coef) = 0.9653. The Weibull modulus of time to failure was in a range of m(sf) = 1.6-1.9 with an average of m(sf) = 1.7 +/- 0.2. A life prediction using the previously determined dynamic fatigue data was in excellent agreement with the static fatigue data. The life prediction approach was also applied to advanced monolithic ceramics and ceramic matrix composites (CMCs) based on their dynamic and static fatigue data determined at elevated temperatures. All of these results indicated that a SCG mechanism governed by a power-law crack growth formulation was operative, a commonality of SCG in these materials systems. C1 [Choi, Sung R.; Faucett, D.

Estimates of HIV prevalence in African military personnel are scarce and inconsistent. We conducted a serosurvey between June and September 2007 among 4043 Armed Forces personnel of the Democratic Republic of Congo (FARDC) stationed in Kinshasa, Democratic Republic of Congo (DRC) to determine the prevalence of HIV and syphilis infections and describe associated risk behaviours. Participants provided blood for HIV and syphilis testing and responded to a demographic and risk factor questionnaire. The prevalence of HIV was 3.8% and the prevalence of syphilis was 11.9%. Women were more likely than men to be HIV positive, (7.5% vs. 3.6% respectively, aOR: 1.66, 95% C. I: 1.21-2.28, p<0.05). Factors significantly associated with HIV infection included gender and self-reported genital ulcers in the 12 months before date of enrollment. The prevalence of HIV in the military appears to be higher than the general population in DRC (3.8% vs. 1.3%, respectively), with women at increased risk of infection. C1 [Rimoin, A. W.; Hoff, N.

We here review the evidence for this claim, with illustrations drawn from recent work on sensors made from gold nanoparticles, carbon nanotubes, and reduced graphene oxide nanoplatelets. These examples can be regarded as being prototypical of disordered nanostructured films formed of primitive objects that are nanoscopic in 3-D, 2-D, and 1-D, respectively.

TI Unusual behavior in magnesium-copper cluster matter produced by helium droplet mediated deposition SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID GENERALIZED GRADIENT APPROXIMATION; MG-CU; EXCHANGE; SYSTEM; FILMS; NANOCOMPOSITE; NANOPARTICLES; COMBUSTION; GROUP-11; ALLOYS AB We demonstrate the ability to produce core-shell nanoclusters of materials that typically undergo intermetallic reactions using helium droplet mediated deposition. Composite structures of magnesium and copper were produced by sequential condensation of metal vapors inside the 0.4 K helium droplet baths and then gently deposited onto a substrate for analysis. Upon deposition, the individual clusters, with diameters similar to 5 nm, form a cluster material which was subsequently characterized using scanning and transmission electron microscopies. Results of this analysis reveal the following about the deposited cluster material: it is in the un-alloyed chemical state, it maintains a stable core-shell 5 nm structure at sub-monolayer quantities, and it aggregates into unreacted structures of similar to 75 nm during further deposition. Surprisingly, high angle annular dark field scanning transmission electron microscopy images revealed that the copper appears to displace the magnesium at the core of the composite cluster despite magnesium being the initially condensed species within the droplet. This phenomenon was studied further using preliminary density functional theory which revealed that copper atoms, when added sequentially to magnesium clusters, penetrate into the magnesium cores.

This study evaluated the effectiveness of the 23-valent polysaccharide pneumococcal vaccine (PPV23) in reducing pneumonia in healthy military trainees. Methods: From 2000-2003, 152 723 military trainees from 5 US training camps were enrolled in a doubleb-lind, placebo-controlled trial of PPV23. Participants were closely monitored during basic training for radiographically confirmed pneumonia etiology and loss-of-training days. Participants were also followed using electronic medical encounter data until I June 2007 for three additional outcomes: any-cause pneumonia, any acute respiratory disease, and meningitis. Results: Comparison of demographic data by study arm suggested the randomization procedures were sound. During basic training, 371 study participants developed radiographically confirmed pneumonia. None had evidence of S. pneumoniae infection, but other etiologies included adenovirus (38%), Chlamydophila pneumoniae (9%), and Mycoplasma pneumoniae (8%). During the follow-up period, many study participants, in both the vaccine and placebo groups, had clinical encounters for the medical outcomes of interest. However, Cox's proportional hazard modeling revealed no evidence of a protective vaccine effect during recruit training (radiographically confirmed pneumonia) or up to 6.7 years after enrollment (any-cause pneumonia, any acute respiratory disease, or meningitis). Conclusions: Data from this large, double-blind, placebo controlled trial do not support routine use of PPV23 among healthy new military trainees. Published by Elsevier Ltd.

This research was undertaken to understand the extent to which microscale (10's of mu m) particles are produced when macroscale residues are weathered by artificial precipitation. Initial experiments, in which artificial rainwater was applied drip-wise to single chunks of Composition B detonation residues from multiple heights, confirmed that microscale particles were produced during precipitation-driven aging, with 30% of the explosive mass collected detected as particulate Composition B (e.g., particles >0.45 mu m in diameter). Follow-on experiments, during which multiple cm-sized residue chunks were subjected to realistic simulated precipitation, demonstrated an initial large pulse of particulate Composition B, followed by sustained production of microscale particles that represented 15-20% of recovered explosives. These findings indicate that the effective footprint of detonation residues likely increases as particulates are produced by the production and spreading of microscale particles across the soil surface. Combined with results published elsewhere that microscale particles can move into porous media to become a distributed source term, these findings point to the need for inclusion of these processes in explosive contaminant fate and transport modeling.

TI Composite-Light-Pulse Technique for High-Precision Atom Interferometry SO PHYSICAL REVIEW LETTERS LA English DT Article ID STIMULATED RAMAN TRANSITIONS; MAGNETOMETER AB We realize beam splitters and mirrors for atom waves by employing a sequence of light pulses rather than individual ones. In this way we can tailor atom interferometers with improved sensitivity and accuracy. We demonstrate our method of composite pulses by creating a symmetric matter-wave interferometer which combines the advantages of conventional Bragg- and Raman-type concepts. This feature leads to an interferometer with a high immunity to technical noise allowing us to devise a large-area Sagnac gyroscope yielding a phase shift of 6.5 rad due to the Earth's rotation. With this device we achieve a rotation rate precision of 120 nrad s(-1) Hz(-1/2) and determine the Earth's rotation rate with a relative uncertainty of 1.2%.

TI Variation of Methods in Small-Scale Safety and Thermal Testing of Improvised Explosives SO PROPELLANTS EXPLOSIVES PYROTECHNICS LA English DT Article DE Small-scale safety testing; Homemade explosives; Improvised explosives; Impact; Friction; Electrostatic discharge ID INITIATION; IMPACT AB One of the first steps in establishing safe handling procedures for explosives is small-scale safety and thermal (SSST) testing. To better understand the response of homemade or improvised explosives (HMEs) to SSST testing, 16 HME materials were compared to three standard military explosives in a proficiency-type round robin study among five laboratories, two U.S. Department of Defense and three U.S. Department of Energy, sponsored by the Department of Homeland Security, Science & Technology Directorate, Explosives Division. The testing included impact, friction, electrostatic discharge (ESD) and thermal. The testing matrix was designed to address problems encountered with improvised materials: powder mixtures, liquid suspensions, partially wetted solids, immiscible liquids, and reactive materials. All testing materials and/or precursors came from the same batch distributed to each of the participants and were handled, pretreated, and mixed by standardized procedures. For this proficiency test, the participants had similar equipment, usually differing by vintage. This allowed for a direct comparison of the results from each participant to the average of the results from all the participants. Some general trends observed for each series of tests were: (1) Drop hammer - LLNL usually found the materials less sensitive than the average with materials that have high sensitivity to impact and LANL usually found the materials less sensitive than the average with materials that have high sensitivity to impact; (2) friction - LLNL found the materials less sensitive than the average; (3) and ESD - IHD usually found the materials less sensitive than the average. In this report, the proficiency test data from all the participants is compared and contrasted for impact, selected friction, and ESD testing. Other friction and thermal data will be addressed elsewhere as well as the statistical analysis of several repeated measurements on the proficiency test standards.

TI Optical characterization and confocal fluorescence imaging of mechanochromic acrylate polymers SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID POLYMERIZATION; SPIROPYRAN; ACTIVATION AB The development of mechanochromic molecules has opened new pathways for the study of localized stress and failure in polymers. Their application as stress or temperature diagnostics, however, requires suitable measurement techniques capable of detecting the force-and temperature-sensitive chemical species with high spatial resolution. Confocal imaging techniques offer excellent spatial resolution but the energy input during these measurements can itself affect the activation state of the mechanochromic species. Here, we present a systematic study of the effects of laser-based imaging on the activation and fluorescence behavior of mechanochromic spiropyran (SP) integrated into poly( methyl acrylate) (PMA) and poly(methyl methacrylate) matrices using a confocal Raman microspectrometer. Localized stress and temperature activation were studied by means of high-rate compressive loading and dynamic fracture. Laser illumination of SP in PMA revealed a strong excitation wavelength-and power-dependence. Suitable correction functions were established and used to account for the observed laser effects. The presented study demonstrates that confocal imaging using conventional Raman spectrometers is a powerful characterization tool for localized stress analysis in mechanochromic polymers, offering quantifiable information on the activation state with high spatial resolution. However, laser-mechanophore interactions must be well understood and effects of laser excitation and exposure times must be taken into consideration when interpreting the obtained results.

To determine kia, we measured the trap loading and loss rates from both a Na magneto-optical trap (MOT) and a linear radio-frequency quadrupole Paul trap. We found the total rate coefficient to be 7.4 +/- 1.9 x 10(-8) cm(3)/s for the type-I Na MOT immersed within an approximate to 140-K ion cloud and 1.10 +/- 0.25 x 10(-7) cm(3)/s for the type-II Na MOT within an approximate to 1070-K ion cloud. Our measurements show excellent agreement with previously reported theoretical fully quantal ab initio calculations. In the process of determining the total rate coefficient, we demonstrate that a MOT can be used to probe an optically dark ion cloud's spatial distribution within a hybrid trap. C1 [Goodman, D.

Their large platform size also makes them unfavorable for compact, autonomous systems. In recent years, researchers at NAVAIR in Patuxent River, MD have developed a compact submersible laser imaging system based on a multistatic system architecture, allowing the source and multiple receivers to reside on separate, smaller, independent platforms. The system geometry can be better optimized for the environment, allowing it to obtain high quality imagery through much higher attenuation lengths (between the target and receiver) when compared to conventional imaging systems. The smaller source also lends itself to integration into an autonomous underwater vehicle (AUV). A compact, multistatic imaging system designed for integration into a REMUS 600 AUV has been developed and is currently being tested in a laboratory environment. System design and laboratory test plans will be presented. C1 [Alley, Derek; Cochenour, Brandon; Mullen, Linda] Naval Air Syst Command, Patuxent River, MD 20670 USA.

The goal is to show that high resolution time of flight measurements to underwater targets can be obtained utilizing far fewer samples than dictated by Nyquist sampling theorems. Traditional mixing/down-conversion and matched filter signal processing methods are reviewed and compared to the Compressive Sampling and Sparse Reconstruction methods. Simulated evidence is provided to show the possible sampling rate reductions, and experiments are used to observe the effects that turbid underwater environments have on recovery. Results show that by using compressive sensing theory and sparse reconstruction, it is possible to achieve significant sample rate reduction while maintaining centimeter range resolution.

The transmitter approach is based on small-footprint, low-cost components, using low coherence time laser diodes and passive fiber processors to generate wideband noise-like intensity modulation signals in the blue-green optical spectrum. Prototype transmitters are demonstrated using both blue and green laser diodes with passive fiber interferometer structures. Laboratory water tank experiments using a two-diode 516/518 nm prototype transmitter show centimeter range error and 30 cm range resolution while detecting a submerged gray target in up to ten attenuation lengths of turbid water. Experimentally observed challenges for target rangefinding are discussed, including shot noise, backscatter returns, and self-clutter. Strategies are proposed to mitigate these challenges and enhance performance when operating at long standoff distances in turbid waters.

GP IEEE TI The Influence of High C Rate Pulsed Discharge on Lithium-ion Battery Cell Degradation SO 2015 IEEE PULSED POWER CONFERENCE (PPC) LA English DT Proceedings Paper CT 2015 IEEE Pulsed Power Conference (PPC) CY MAY 31-JUN 04, 2015 CL Austin, TX ID MECHANISMS; SEI AB Over the past decade, lithium-ion battery (LIB) technology has advanced beyond the scope of simple consumer electronic devices. Nowadays, LIBS of advanced, high power chemistries are being used as a prime power source for many large scale applications, such as electric automobiles and pulsed power platforms, which require a higher standard of performance. LIB degradation mechanisms have been studied thoroughly for decades in nominal rate cycling applications. The common mechanisms that attribute to cell capacity fade and failure are well documented in these cases. However, recent studies into cells cycled at rates above five times their nominal capacity rate show that some degradation mechanisms become more favorable than others. In some extreme cases, cell failure can occur abruptly during ultra-high rate pulsed discharged cells as a result of accelerated degradation phenomenon occurring at the surface of the cell electrode materials. In the work presented here, lithium iron phosphate (LFP) cells have been cycled at 15C with a pulsed discharge profile and the results show unique capacity fade when compared to previously published studies. An abrupt decrease in the usable capacity fade occurs within forty cycles of high rate operation. Electrochemical impedance spectroscopy (EIS) shows that there is a separation in the EIS spectrum over the lifetime of the cell indicating a dominant failure mechanism which is responsible for failure. Electron micrographs of the electrodes surfaces show large SEI buildup on the surface of the graphite anode. However, the buildup is uneven across the length of the roll with the bulk of the growth occurring on the material near the cell core. Areas of graphite anode near the edge of the cell show far less growth and contain small areas that are relatively unaffected by solid-electrolyte interphase (SET) layer buildup. Overall, the evidence further indicates that the previously presented studies on LIB degradation mechanisms is insufficient for characterizing degradation in cells cycled at ultra-high rates with a pulsed discharge profile. These mechanisms must be understood in order to fully understand how these cells will behave and perform when they are used at high pulsed rates in future, compact, high energy, and high pulsed power systems.

Currently, there are number of American Society for Testing and Materials (ASTM) test standards for CMC's at both ambient and elevated temperatures, including interlaminar tension and shear strength test methods. However, there are no standardized test methods for determination of interlaminar fracture toughness in CMC's. Although research work exists on interlaminar Mode I and Mode II fracture toughness of various types of CMC's, the test methods applied particularly in Mode II fracture toughness testing showed definite drawbacks and limitations. ASTM test standards for CMC's may exhibit a zig-zag (wavy) crack path pattern, and fiber bridging. The experimental parameters that may contribute to the difficulty can be summarized as: specimen width and thickness, interface coating thickness, mixed mode failure evolution, and interlaminar defects. Modes I and II crack growth resistances, G(I) and G(II), were analytically determined at ambient temperature using double cantilever beam (DCB) and End Notched Flexure (ENF) geometries. Three (3) CMC material systems were analyzed (Sylramic/IBN/MI, SiC/SiC CVI, and SiC/CAS). Several Finite Element (FE) based potential techniques were investigated: a) Multi-scale progressive failure analysis (MS-PFA); b) Virtual Crack Closure Technique (VCCT); and c) Contour Integral (CI). Advantages and disadvantages of each were identified. The final modeling algorithm recommended was an integrated damage and fracture evolution methodology using MS-PFA and VCCT. The analysis results (Fracture energy vs. crack length, Fracture energy vs. load, Fracture energy vs. crack opening displacement) matched the Mode I and Mode II coupon tests and revealed the following key findings. Mode I-DCB specimen: 1) Sylramic/IBN/MI failure mode is due to interlaminar tension (ILT) only in the interface section and a zigzag pattern observed 2) VCCT crack growth resistance of Sylramic/IBN/MI is well matched to the test data and 3) SiC/SiC CVI failure mode is a mixed mode behavior (ILT to interlaminar shear (ILS). Mode II ENF specimen MS-PFA analysis suggests mixed mode behavior and the zig-zag pattern similar to Mode I coupon tests.

The effectiveness and reliability of a repair are highly reliant on the patch design, bondline properties, and processing and fabrication parameters. To explore an optimal repair within a design space, most of the current modeling and simulations are performed based on a single failure mechanism along the bondline without considering other aging and damage mechanisms in the composite patch and aluminum structures. A Hybrid Structure Evaluation and Fatigue Damage Assessment (HYSEFDA) toolkit based on an Abaqus/Implicit platform has been developed to access the residual strength and fatigue life of a composite patch repaired metallic structure. A mesh independent, phantom-paired element based extended finite element method (XFEM) and a cohesive spring element is employed to describe the discrete cracks in the metallic layer and the adhesive interface between the metal layer and the composite patch, respectively. A virtual crack closure technique (VCCT) approach is adopted to extract the energy release rate at the crack tip and delamination front, which is tracked by a developed geometrical mapping algorithm. In order to capture other damage and aging mechanisms, a continuum damage mechanics (CDM) approach is applied to characterize inter and intra ply damage. In addition, the plasticity induced crack closure effect is also investigated by implementing a plastic hardening model into the HYSEFDA toolkit. The HYSEFDA toolkit is used to evaluate the fatigue life of an aluminum plate repaired by E-Glass epoxy composite patch tested by the Naval Surface Warfare Center, Carderock Division. Parametric studies are performed to examine the effects of patch damage on the bridging of a fatigue crack in an aluminum plate.

Because sexual harassment and assault are more closely intertwined in the military than in most civilian contexts, the military context affords a unique opportunity to study the interrelationships between these two types of sexual violence. In this review, we briefly summarize existing research on military sexual trauma prevalence rates, effects on victims, and risk factors, as well as prevention and response programs in the military context. In each of these topic areas, we emphasize issues unique to the complex interplay between sexual harassment and assault in the military and make recommendations for future research.

The symposium was held to provide a state-of-the-science meeting on the U.S. DoD's rescinding of the ground combat exclusion policy opening up combat-centric occupations to women. Physiological, metabolic, body composition, bone density, cardiorespiratory fitness, and thermoregulation differences between men and women were briefly reviewed. Injury epidemiological data are presented within military training and operational environments demonstrating women to be at a higher risk for musculoskeletal injuries than men. Physical training considerations for improved muscle strength and power, occupational task performance, load carriage were also reviewed. Particular focus of this article was given to translating physiological and epidemiological findings from the literature on these topics toward actionable guidance and policy recommendations for military leaders responsible for military physical training doctrine: (1) inclusion of resistance training with special emphasis on strength and power development (i.e., activation of high-threshold motor units and recruitment of type II high-force muscle fibers), upper-body strength development, and heavy load carriage, (2) moving away from "field expediency" as the major criteria for determining military physical training policy and training implementation, (3) improvement of load carriage ability with emphasis placed on specific load carriage task performance, combined with both resistance and endurance training, and (4) providing greater equipment resources, coaching assets, and increased training time dedicated to physical readiness training.

U.S. service-women who sustained combat-related injury in Operation Iraqi Freedom (OIF) or Operation Enduring Freedom (OEF) between January 2003 and May 2014 were identified from the Expeditionary Medical Encounter Database. Injuries were characterized using Abbreviated Injury Scale and International Classification of Diseases, 9th Revision codes. Of the 844 combat-related injury episodes in women, 51% (n = 433) were OIF injuries and 49% (n = 411) were OEF injuries. Blast events were responsible for 90% of injuries. The average Injury Severity Score was 3, with no statistical difference in means between OIF and OEF. Of significance were increased head injuries in OEF compared with OIF (80% vs. 48%; p < 0.001). Although the majority of combat-related injuries suffered by women were mild, some women suffered life-threatening injuries, and nearly 65% of the injury episodes resulted in more than one injury. More research is needed as the roles of women in the military continue to expand. Future studies will investigate quality of life outcomes and gender differences in combat-related injuries.

Probability distributions, in general, describe the percentage of items that have a particular value in a data set. Empirical examples of power law distributions typically involve a small group of "bad actors" within a population that cause the tail of the distribution to skew away from that of a straight line. Avionics failures within the Naval Air Enterprise (NAE) also typically involve a small population of bad actors which account for a large portion of failure conditions. Therefore, the authors were eager to investigate whether Navy and Marine Corps avionics systems failures fit a power law distribution. If so, it would suggest that radical change is needed to current maintenance practices, including a change in investments in automatic test equipment. To address this question, the top five hundred avionics degraders from across the NAE were analyzed using a method laid out by Clauset, et al [1]. First, data was gathered and candidate systems were identified using visual inspection of the data. Data from candidates was then analyzed such that the tail of the distribution could be compared to the power law distribution. Finally, a goodness of fit calculation was performed to find whether or not the power law distribution appropriately described the behavior of the candidate system. All power law candidates were then compared to other types of distributions. This information was used to determine if the power law distribution truly is the favored distribution for a given data set. Analysis was done on two data sets: one from 2000 to 2010 and with data from 2010 to mid-2015. It was found that the results from this comparison favored other types of distributions over the power law in almost every case. Furthermore, it was found that no-fault-found maintenance actions can create the illusion of power law failure behavior in some systems, where none actually exists.

An integrated numerical model consisting of a DBD electro-hydrodynamic (EHD) body force model and computational fluid dynamics (CFD) package called NavyFoam is employed in this study. The EHD body force is calculated by solving the Partial Deferential Equation (PDE)-based electrostatic equations for electric potential due to applied voltage and net charged density due to ionized air. The electric potential equation, the net charge density equation, and the flow equations are solved in separate computational domains. Comparison of current computational results against experimental data indicates reasonable agreement between the two studies for the baseline flow as well as controlled cases using two AC waveforms including sine and pulse-amplitude modulated sine with different modulation frequencies. Performance of the actuator is also examined for the square and pulse AC waveforms. It is found that at the experimental conditions, the pulse amplitude-modulated sine waveform provides the most lift enhancement in comparison with other waveforms used in this study, despite the least power input that it requires to operate. The effect of the input voltage amplitude on the performance of the actuator is also examined for the sine and pulse-amplitude-modulated sine waveforms. It is shown that beyond a critical voltage, the sine wave is more effective in improving the aerodynamic performance of the airfoil than the other waveform.

The model is applied to reduce the ideal tangential velocity and provides an estimation of the impeller exit velocity and blade loading for use in turbomachinery meanline modeling. Wiesner reviewed all the proposed models in 1967 and came up with a set of formulations which are only dependent on the impeller geometry, such as number of blades, exit blade angle and blade inlet-to-exit radius ratio. In order to cover flow induced effects and off-design conditions, Qiu recently proposed a formula which contains the effects from the radial rotation, blade turning and passage width variation. For a centrifugal impeller, often the impeller exit condition is affected by downstream components. Pfleiderer's model of 1961 includes effects of downstream vaned diffuser, vaneless diffuser, or a volute. This paper focuses on the comparisons of the three models in predicting blade loading for a centrifugal-fan impeller with a double-discharge volute at both design and off-design conditions. The comparisons reveal not only each model's prediction accuracy, but also the flexibility of each model. C1 [Lee, Yu -Tai] Naval Surface Warfare Ctr, Carderock Div, Bethesda, MD USA.

The EHD body force model is based on solving the electrostatic equations for the electric potential due to applied voltage and the net charge density due to ionized air. The boundary condition for the charge density on the dielectric surface is obtained from a Space-Time Lumped-Element (STLE) circuit model that accounts for the time and space dependence of air ionization on the input voltage amplitude, frequency, electrode geometry, and dielectric properties. The development of the numerical simulation. tool is based on the framework of NavyFOAM using a multi-domain approach. The electric potential equation, the net charge density equation, and the flow equations are solved in separate computational domains. All equations are discretized in space using the cell-centered finite volume method. Parallel computation is implemented using domain-decomposition and message passing interface (MPI). Due to a large disparity in time scales between the electric discharge and the flow, a multiple sub-cycle technique is used in coupling the plasma solver and the flow solver. This paper focuses on its application to numerical simulation of flow separation and control over a high-lift flapped airfoil at a Reynolds number of 240,000. The 2-D unsteady RANS simulation utilized the Wilcox k-omega, the SST k-omega, and the k-kl-omega turbulence models. For the baseline case, in comparison with the measurement, the k-kl-omega model captures the feature of the unsteadiness of flow field associated with flow separation and shedding of vortices, better than the Wilcox k-omega and SST k-omega models. In the RANS simulations for flow separation control with DBD plasma actuation, the actuator is driven by voltage signals of a continuous or an amplitude-modulated sine waveform with a range of voltage amplitudes. The numerical results indicate that the modulated forcing is more effective than the continuous forcing for a certain range of applied voltages. The electrical power consumption calculated by the plasma model fits to a parabolic curve as a function of the root-mean-square of applied voltage.

For flow problems consisting of both stationary and rotating parts, e.g. the stator and the rotor of a turbine, or the hull and propeller of a ship, the multiple reference frames (MRF) approach has been widely used. In most existing MRF models, the computation domain is divided into stationary and rotating zones. In the stationary zone, the flow equations are formulated in the inertial frame, while in the rotating zone, the equations are solved in the non-inertial rotating frame. Also, the flow is assumed to be steady in both zones and the flow solution in the rotating zone can be interpreted as the phase-locked time average result. Compared with other approaches, such as the actuator disk (body-force) model, the MRF approach is superior because it accounts for the actual geometry of the rotating part, e.g. propeller blades. A more complicated situation occurs when the flow solver is coupled to the six degrees of freedom (6-DOF) equations of rigid-body motion in predicting the maneuver of a self-propelled surface or underwater vehicle. In many applications, the propeller is replaced by the actuator disk model. The current work attempts to extend the MRF approach to the 6-DOF maneuvering problems. The governing equations for unsteady incompressible flow in a non-inertial frame have been extended to the flow equations in multiple reference frames: a hull-fixed frame that undergoes translation and rotation predicted by the 6-DOF equations of motion and a propeller-fixed frame in relative rotation with respect to the hull. Because of the large disparity between time scales in the 6-DOF rigid body motion of the hull and the relative rotational motion of the propeller, the phase-locked solution in the propeller MRF zone is considered a reasonable approximation for the actual flow around the propeller. The flow equations are coupled to the 6-DOF equations of motion using an iterative coupling algorithm. The coupled solver has been developed as part of NavyFOAM. The theoretical framework and the numerical implementation of the coupled solver are outlined in this paper. Some numerical test results are also presented.

Patients had serious lower-limb injuries (n = 170) or unilateral (n = 460) or bilateral (n = 153) lower-limb amputation(s). Total costs over the follow-up period (2003 to 2012) and annual costs were analyzed. Unadjusted mean costs per year in 2012 U.S. dollars were $7,200, $ 14,700, and $18,700 for limb injuries and unilateral and bilateral lower-limb amputation(s), respectively (p < 0.001). Multivariate modeling indicated that annual cost declined after the first year in the VA for Veterans with limb injuries (p < 0.001, repeated measures). In contrast, annual costs doubled after 3-5 years with unilateral (p < 0.001) and bilateral amputation(s) (p < 0.001). Among amputees, prosthetics comprised more than 50% of outpatient cost; unadjusted mean cost per year for prosthetics was 7-9 times higher in comparison with Veterans with limb injuries. Amputation status was associated with an adjusted 3.12-fold increase in mean prosthetic cost per year (p < 0.001, general linear model). In addition, posttraumatic stress disorder (PTSD) was associated with increased prosthetic cost by amputation status (p < 0.001) and increased psychiatric and pharmacy costs (both p < 0.001). Results indicate relatively high and sustained outpatient costs driven by prosthetics following amputation. Finally, PTSD affected cost for multiple domains of health, highlighting the importance of accurate diagnosis, treatment, and support for PTSD.

Recently, dust flames have become a promising candidate to counter biological warfare. Sulfur in particular is one of the elements that is of interest, but sulfur dust flames are not well understood. Flame temperature and flame speed were measured for sulfur flames with particle concentrations of 280 and 560 g/m(3) and oxygen concentration between 10% and 42% by volume. The flame temperature increased with oxygen concentration from approximately 900 K for the 10% oxygen cases to temperatures exceeding 2000 K under oxygen enriched conditions. The temperature was also observed to increase slightly with particle concentration. The flame speed was observed to increase from approximately 10 cm/s with 10% oxygen to 57 and 81 cm/s with 42% oxygen for the 280 and 560 g/m(3) cases, respectively. A scaling analysis determined that flames burning in 21% and 42% oxygen are diffusion limited. Finally, it was determined that pressure-time data may likely be used to measure flame speed in constant volume dust explosions.

Direct band gap semiconductors have high radiative efficiency and have the potential of high photon yield per unit energy deposited, which are desirable features for a scintillator used for pulse height analysis. In this paper we present our computational results obtained using SRIM software for select materials. The expected depth profiles of implanted hydrogen ions have been applied to the n-p elastic recoil process in both InP and GaN. It is shown that, under ideal conditions, neutron irradiation of hydrogen implanted InP and GaN creates proton recoil scintillation with photon output being directly proportional to incoming neutron energy. It has been found that for the desirable dynamic range of neutron energies, loss to phonon creation in the lattice is negligible compared to energy used in electron excitation which results in the linear response in energy versus pulse height spectrum.

Fused multi-sensor systems are desirable to ensure these operations are highly reliable under the most demanding at-sea conditions, particularly in degraded visual environments. The US Navy Sea-Based Automated Launch & Recovery System (SALRS) program aims at enabling automated/semi-automated launch and recovery of sea-based, manned and unmanned, fixed-and rotary-wing naval aircraft, and to utilize automated or pilot-augmented flight mechanics for carefree shipboard operations. This paper describes the goals and current results of SALRS Phase 1, which aims at understanding the capabilities and limitations of various sensor types through sensor characterization, modeling, and simulation, and assessing how the sensor models can be used for aircraft navigation to provide sufficient accuracy, integrity, continuity, and availability across all anticipated maritime conditions.

In particular, the characterization of temporal dispersion is of paramount importance in order to predict the bandwidth and capacity of underwater optical channels. While the temporal aspects of underwater laser propagation have received attention from the modeling community in the past, few if any of these models have been validated with experimental data. However recent advances in hardware technology now enable experimental characterization at high speeds (GHz). Such measurements have been made by the authors.1 In this work, we develop a Monte Carlo model, and present initial results validated against the aforementioned experimental data.

In adapting this technique from the radar community, a laser is intensity-modulated with a linear frequency ramp. A custom wideband laser source modulated by a new wideband digital synthesizer board is used to transmit an 800 MHz wide chirp into the underwater channel. The transmitted signal is mixed with a reference copy to obtain a "beat" signal representing the distance to the desired object. The expected form of the return signal is derived for turbid waters, a highly scattering environment, indicating that FMCW can detect both the desired object and the volumetric center of the backscatter "clutter" signal. This result is verified using both laboratory experiments and a realistic simulation model of the underwater optical channel. Ranging performance is explored as a function of both object position and water turbidity. Experimental and simulated results are in good agreement and performance out to ten attenuation lengths is reported, equivalent to 100 meters in open ocean or 5 meters in a turbid harbor condition.

Ideal host materials have low loss at the laser transition frequency. This becomes more important as the gain length increases or a low gain transition is of interest. Unfortunately, single crystal YAG suffers from relatively high scatter caused by strain induced index of refraction variations generated by the growth method. For this reason polycrystalline YAG has been developed with virtually no strain. Furthermore, this material can be doped with concentrations that vary spatially. This can provide a tremendous advantage in matching the gain volume to the mode volume in a laser. However, because of the grain boundaries and porosity, polycrystalline materials have scatter loss. Angle resolved, in-plane scatter measurements of polycrystalline YAG and Nd: YAG are reported from 405 to 1064 nm. This covers the range of interest for laser operation but also with enough bandwidth to derive a physical understanding of the scatter mechanisms. A model is also applied to provide physical insight and interpolation and meaningful extrapolation of the experimental results. C1 [Springer, R.

Aluminum hydride particles were heated on a platinum filament at heating rates of approximately 1 x 10(5) K/s in a pressure vessel for pressures ranging up to about 7 MPa, in order to quantify the ignition temperature and to observe the ignition process. Experiments were conducted in air, argon, and nitrogen as the pressurizing environment. This study revealed that the dehydrogenation of aluminum hydride is not a function of pressure under the conditions tested. In addition, ignition temperatures were found to be approximately linearly related to pressure until pressures exceeded about 0.4 MPa, at which point they remained constant through the highest pressures tested. High speed imaging of the ignition process showed a dramatic change in the ignition behavior for pressures above 0.4 MPa, corresponding to what we believe is a threshold for H-2/air autoginition or perhaps even an explosion limit. We find that the combustion behavior of aluminum hydride particles shared many traits similar to what has been previously observed with aluminum particles including a diffusion flame surrounding the particle, spinning, jetting, and explosions/fragmentation. Quenched particles also showed clear evidence of gas phase combustion with parent particles containing nanofeatures, which were condensed from the gas phase. The results of this study provide additional understanding on the ignition and combustion process of aluminum hydride at extreme conditions, which may be useful in modeling efforts or in the development of solid propellants.

TI Defective by design: vanadium-substituted iron oxide nanoarchitectures as cation-insertion hosts for electrochemical charge storage SO JOURNAL OF MATERIALS CHEMISTRY A LA English DT Article ID LITHIUM-ION BATTERIES; K-EDGE; AEROGELS; V2O5; NANOPARTICLES; GAMMA-FE2O3; MONOLITHS; EPOXIDES; IFEFFIT; CATHODE AB Vanadium-substituted iron oxide aerogels (2 : 1 Fe : V ratio; VFe2Ox) are synthesized using an epoxide-initiated sol-gel method to form high surface-area, mesoporous materials in which the degree of crystallinity and concentration of defects are tuned via thermal treatments under controlled atmospheres. Thermal processing of the X-ray amorphous, as-synthesized VFe2Ox aerogels at 300 degrees C under O-2-rich conditions removes residual organic byproducts while maintaining a highly defective gamma-Fe2O3-like local structure with minimal long-range order and vanadium in the +5 state. When as-synthesized VFe2Ox aerogels are heated under low partial pressure of O-2 (e.g., flowing argon), a fraction of vanadium sites are reduced to the +4 state, driving crystallization to a Fe3O4-like cubic phase. Subsequent thermal oxidation of this nanocrystalline VFe2Ox aerogel re-oxidizes vanadium +4 to +5, creating additional cation vacancies and re-introducing disordered oxide domains. We correlate the electrochemical charge-storage properties of this series of VFe2Ox aerogels with their degree of order and chemical state, as verified by X-ray diffraction, X-ray photoelectron spectroscopy, and X-ray absorption spectroscopy. We find that the disordered O-2-heated VFe2Ox aerogel yields the highest Li+- and Na+-insertion capacities among this series, approaching 130 mA h g(-1) and 70 mA h g(-1), respectively. Direct heat-treatment of the VFe2Ox aerogel in flowing argon to yield the partially reduced, nanocrystalline form results in significantly lower Li+-insertion capacity (77 mA h g(-1)), which improves to 105 mA h g(-1) by thermal oxidation to create additional vacancies and structural disorder.

Samples were deposited on filaments, which were rapidly heated by joule heating under various conditions. Dehydrogenation experiments were conducted under vacuum conditions at heating rates of up to 4 x 10(5) K/s. The results of these experiments suggest that, at high heating rates, the onset of dehydrogenation is limited by intraparticle diffusion. The ignition and combustion behavior was studied in air and for ambient pressures ranging from atmospheric up to 7 MPa in a windowed pressure vessel. Broadband light emission was used to quantify the ignition temperature. The experiments revealed that the ignition temperature decreased linearly with increasing pressure from approximately 1700 K to 1475 K. Comparison of the dehydrogenation temperatures to the ignition temperatures over the entire pressure range suggests that the onset of the dehydrogenation process is not likely to be affected by ambient pressure. Finally, observation of the steady state combustion process by high speed imaging and post mortem analysis revealed many similar combustion characteristics to pure titanium. Particle explosions were observed and quenched particles were found to consist of titanium, nitrogen, and oxygen.

The experiment consisted of creating a periodic water jet array inside a focused beam measurement system. The focused beam system measures the radio frequency (RF) response to a finite array of free flowing water jets. The results of the experiment are compared to a one-dimensional Rigorous Coupled-Wave Analysis (RCWA) prediction for infinitely periodic cylinders of water. The consistency between the measured and predicted values appears to validate the permittivity of fresh water at 13 degrees C in C-Band as predicted by the Meissner and Wentz model. This method for measuring and predicting the one-dimensional RCWA solver could be used to characterize properties of other liquids.

Surveys assessed demographics, service characteristics, PTSS, and coping strategies used during mock captivity. Participants used seven coping strategies: denial, self-blame, religion, self-distraction, behavioral disengagement, positive reframing, and planning. Women used denial (p <= .05), self-blame (p <= .05), and positive reinterpretation (p <= .05) strategies more frequently than men, and they had higher PTSS levels following the exercise. Structural equation modeling showed that the relationship between sex and PTSS was fully Mediated by coping strategies. The results of this study suggest that reducing the use of maladaptive coping strategies may mitigate PTSS among females. Future efforts should target improving coping during highly stressful and traumatic experiences. (C) 2014 Elsevier Ltd. All rights reserved.

TI Modeling Rotor Unsteady Forces and Sound Due to Homogeneous Turbulence Ingestion SO AIAA JOURNAL LA English DT Article ID GRID-GENERATED TURBULENCE; INFERRING PROPELLER INFLOW; NEAR-FIELD RESPONSE; ASYMPTOTIC THEORY; PART 2; NOISE; RADIATION; THRUST AB An analytical approach is presented to model the broadband unsteady force cross-correlations exerted on a rotor due to a spatially homogeneous turbulent inflow. In addition, the rotor unsteady force cross-correlation matrix is treated as a set of correlated, compact dipole acoustic sources to predict the low-frequency radiated sound field of a subsonic rotor ingesting a turbulent flow. It is shown that turbulence-induced rotor forces in the radial and axial directions are uncorrelated for the special condition when spatially homogeneous turbulence is ingested, and further it is shown that radial-to-axial force correlation can exist when the turbulent inflow velocity field contains a coherent once-per-revolution variation. Equations to estimate rotor turbulence ingestion sound from noncompact dipole sources are also developed for situations when the compact acoustic assumption is invalid. A numerical simulation of the turbulence force and acoustic response for a 10-bladed rotor ingesting a spatially homogeneous turbulent inflow closely match an available experimental data set. A numerical simulation was also performed for a variation in rotor blade pitch, which indicated that radial force dipole source strength becomes nearly comparable to axial force dipole source strength when the blade-tip pitch angle reaches a value of pi/4.

Data were drawn from the Millennium Cohort Study. Self-reported data and objective military service data were used to assess exposures and outcomes. Among all 48,540 participants, 7.5% self-reported new-onset hearing loss. Self-reported hearing loss showed moderate to substantial agreement (k = 0.57-0.69) with objective audiometric measures. New-onset hearing loss was associated with combat deployment (adjusted odds ratio [AOR] = 1.63, 95% confidence interval [CI] = 1.49-1.77), as well as male sex and older age. Among deployers, new-onset hearing loss was also associated with proximity to improvised explosive devices (AOR = 2.10, 95% CI = 1.62-2.73) and with experiencing a combat-related head injury (AOR = 6.88, 95% CI = 3.77-12.54). These findings have implications for health care and disability planning, as well as for prevention programs. C1 [Wells, Timothy S.] Adv Analyt Optum, Ann Arbor, MI USA.

There has been little scientific evidence of the effectiveness of this type of system for rehabilitation. OBJECTIVE: A systematic review of the literature was completed to determine what type of work has been performed on the CAREN and report findings of clinical significance. METHODS: Specific terms were searched on electronic databases to include journal articles, abstracts, and peer-reviewed conference proceedings related to the CAREN. RESULTS: Twenty-six publications were elicited that met our criteria. These were divided by their primary focus: rehabilitation, clinical research, and technical reports. DISCUSSION: Results from published articles have determined that the system is a capable tool for both assessment and rehabilitation, but little has currently been published, particularly on patient populations. CONCLUSION: More research needs to be performed to evaluate its effectiveness as a rehabilitation tool compared to other rehabilitation methods. It is expected that a system, such as the CAREN, will challenge patients multifactorially (e.g. physically and cognitively) and provide biofeedback while decreasing rehabilitation time and increasing effectiveness of treatment.

Zhao, Weifeng TI Inverse Kinematic Control of a Dual Crane System Experiencing Base Motion SO IEEE TRANSACTIONS ON CONTROL SYSTEMS TECHNOLOGY LA English DT Article DE Control design; kinematics; motion compensation AB For over 30 years, many active and passive antipendulation concepts have been explored for use on cranes in the marine environment. These range from simple tension member restraints to command filtering strategies and advanced feedback control laws, where both measured ship/platform motion and payload swing are required. Single crane control systems that compensate for own ship or target ship motion and payload swing damping are well developed, and have been demonstrated. Cargo transfer control is more complex when multiple ship-mounted cranes are used, representing a closed kinematic chain. However, the potential benefits include larger capacity and better load control. In this brief, an inverse kinematic control strategy is presented that uses two cranes' actuation capability (hoist lengths and boom angles) to keep its load fixed in inertial space regardless of the motion of the ship on which the cranes are mounted. An underdetermined solution is developed. Unique crane commands can then be computed using a minimum norm solution. A dynamic simulation is described for use in algorithm development and initial validation. Final verification was performed using two cranes mounted on a motion controlled platform.

This study incorporated a whole column axial acceleration model and an isolated vertebral body model to quantify compression rates during realistic loading and compressive tolerance of vertebrae. Eight lumbar columns and 53 vertebral bodies from 23 PMHS were used. Three-factor ANOVA was used to determine significant differences (p <0.05) in physiologic and failure biomechanics based on compression rate, spinal level, and gender. Results demonstrated a significant increase in ultimate force (i.e., fracture) from lower to higher compression rates. Ultimate stress also increased with compression rate. Displacement and strain to failure were consistent at both compression rates. Differences in ultimate mechanics between vertebral bodies obtained from males and females demonstrated non-significant trends, with female vertebral bodies having lower ultimate force that would be associated with decreased injury tolerance. This was likely a result of smaller vertebrae in that population. Combined with existing literature, results presented in this manuscript contribute to the understanding of lumbar spine tolerance during axial loading events that occur in both military and civilian environments with regard to effects of compression rate and gender.

TI Epidemiology of Pathogen-Specific Respiratory Infections among Three US Populations SO PLOS ONE LA English DT Article ID INFLUENZA-LIKE ILLNESSES; VIRAL-INFECTIONS; CLINICAL SIGNS; PCR; SURVEILLANCE; CHILDREN; VIRUSES; COINFECTIONS; PNEUMONIA; COMMUNITY AB Background: Diagnostic tests for respiratory infections can be costly and time-consuming. Improved characterization of specific respiratory pathogens by identifying frequent signs, symptoms and demographic characteristics, along with improving our understanding of coinfection rates and seasonality, may improve treatment and prevention measures. Methods: Febrile respiratory illness (FRI) and severe acute respiratory infection (SARI) surveillance was conducted from October 2011 through March 2013 among three US populations: civilians near the US-Mexico border, Department of Defense (DoD) beneficiaries, and military recruits. Clinical and demographic questionnaire data and respiratory swabs were collected from participants, tested by PCR for nine different respiratory pathogens and summarized. Age stratified characteristics of civilians positive for influenza and recruits positive for rhinovirus were compared to other and no/unknown pathogen. Seasonality and coinfection rates were also described. Results: A total of 1444 patients met the FRI or SARI case definition and were enrolled in this study. Influenza signs and symptoms varied across age groups of civilians. Recruits with rhinovirus had higher percentages of pneumonia, cough, shortness of breath, congestion, cough, less fever and longer time to seeking care and were more likely to be male compared to those in the no/unknown pathogen group. Coinfections were found in 6% of all FRI/SARI cases tested and were most frequently seen among children and with rhinovirus infections. Clear seasonal trends were identified for influenza, rhinovirus, and respiratory syncytial virus. Conclusions: The age-stratified clinical characteristics associated with influenza suggest that age-specific case definitions may improve influenza surveillance and identification. Improving identification of rhinoviruses, the most frequent respiratory infection among recruits, may be useful for separating out contagious individuals, especially when larger outbreaks occur. Overall, describing the epidemiology of pathogen specific respiratory diseases can help improve clinical diagnoses, establish baselines of infection, identify outbreaks, and help prioritize the development of new vaccines and treatments.

The solution-based pyrolysis of a series of heterobimetallic Schiff base complexes ensures a rigorous control of the size, morphology and composition of 3 nm M0.1Ce0.9O2-x crystallites for CO oxidation catalysis and other applications. X-ray absorption spectroscopy confirms the dispersion of aliovalent (M3+ and M2+) transition metal ions into the ceria matrix without the formation of any bulk transition metal oxide phases, while steady-state CO oxidation catalysis reveals an order of magnitude increase in catalytic activity with copper substitution. Density functional calculations of model slabs of these compounds confirm the stabilization of M3+ and M2+ in the lattice of CeO2. These results highlight the role of the host CeO2 lattice in stabilizing high oxidation states of aliovalent transition metal dopants that ordinarily would be intractable, such as Cu3+, as well as demonstrating a rational approach to catalyst design. The current work demonstrates, for the first time, a generalizable approach for the preparation of transition-metal-substituted CeO2 for a broad range of transition metals with unparalleled synthetic control and illustrates that Cu3+ is implicated in the mechanism for CO oxidation on CuO-CeO2 catalysts.

TI An experimentally validated transient thermal model for cylindrical Li-ion cells SO JOURNAL OF POWER SOURCES LA English DT Article DE Lithium-ion cells; Energy conversion; Transient thermal management; Battery cooling; Laplace transforms ID MANAGEMENT-SYSTEM; PHASE-CHANGE; BATTERIES; LITHIUM; PACKS AB Measurement and modeling of thermal phenomena in Li-ion cells is a critical research challenge that directly affects both performance and safety. Even though the operation of a Li-ion cell is in most cases a transient phenomenon, most available thermal models for Li-ion cells predict only steady-state temperature fields. This paper presents the derivation, experimental validation and application of an analytical model to predict the transient temperature field in a cylindrical Li-ion cell in response to time-varying heat generation within the cell. The derivation is based on Laplace transformation of governing energy equations, and accounts for anisotropic thermal conduction within the cell. Model predictions are in excellent agreement with experimental measurements on a thermal test cell. The effects of various thermophysical properties and parameters on transient thermal characteristics of the cell are analyzed. The effect of pulse width and cooling time for pulsed operation is quantified. The thermal response to multiple cycles of discharge and charge is computed, and cell-level trade-offs for this process are identified. The results presented in this paper may help understand thermal phenomena in Li-ion cells, and may contribute towards thermal design and optimization tools for energy conversion and storage systems based on Li-ion cells.

In the present study, we quantified self-reported symptoms from participants in the Millennium Cohort Study, a prospective study representing all US service branches, including both active duty and Reserve/National Guard components (2001-2008). Self-reported symptoms were uniquely compared with those in a cohort of subjects from the 1991 Gulf War to gain context for the present report. Symptoms were then aggregated to identify cases of chronic multisymptom illness (CMI) based on the case definition from the Centers for Disease Control and Prevention. The prevalence of self-reported CMI symptoms was compared with that collected in 1997-1999 from a study population of US Seabees from the 1991 Gulf War, as well as from deployed and nondeployed subgroups. Although overall symptom reporting was much less in the Millennium Cohort than in the 1991 Gulf War cohort, a higher prevalence of reported CMI was noted among deployed compared with nondeployed contemporary cohort members. An increased understanding of coping skills and resilience and development of well-designed screening instruments, along with appropriate clinical and psychological follow-up for returning veterans, might help to focus resources on early identification of potential long-term chronic disease manifestations.

Adenovirus and influenza are the most common etiological agents responsible for febrile respiratory illness (FRI) among trainees and present with similar clinical signs and symptoms. Identifying demographic and clinical factors associated with the primary viral pathogens causing FRI epidemics among trainees will help improve differential diagnosis and allow for appropriate distribution of antiviral medications. The objective of this study was to determine what demographic and clinical factors are associated with influenza and adenovirus among military trainees. Methods: Specimens were systematically collected from military trainees meeting FRI case definition (fever >= 38.0 degrees C with either cough or sore throat; or provider-diagnosed pneumonia) at eight basic training centers in the USA. PCR and/or cell culture testing for respiratory pathogens were performed on specimens. Interviewer-administered questionnaires collected information on patient demographic and clinical factors. Polychotomous logistic regression was employed to assess the association between these factors and FRI outcome categories: laboratory-confirmed adenovirus, influenza, or other FRI. Sensitivity, specificity, positive and negative predictive value were calculated for individual predictors and clinical combinations of predictors. Results: Among 21,570 FRI cases sampled between 2004 and 2009, 63.6% were laboratory-confirmed adenovirus cases and 6.6% were laboratory-confirmed influenza cases. Subjects were predominantly young men (86.8% men; mean age 20.8 +/- 3.8 years) from Fort Jackson (18.8%), Great Lakes (17.1%), Fort Leonard Wood (16.3%), Marine Corps Recruit Depot (MCRD) San Diego (19.0%), Fort Benning (13.3%), Lackland (7.5%), MCRD Parris Island (8.7%), and Cape May (3.2%). The best multivariate predictors of adenovirus were the combination of sore throat (odds ratio [OR], 2.94; 95% confidence interval [CI], 2.66-3.25), cough (OR, 2.33; 95% CI, 2.11-2.57), and fever (OR, 2.07; 95% CI, 1.90-2.26) with a PPV of 77% (p <= .05). A combination of cough, fever, training week 0-2 and acute onset were most predictive of influenza (PPV = 38%; p <= .05). Conclusions: Specific demographic and clinical factors were associated with laboratory-confirmed influenza and adenovirus among military trainees. Findings from this study can guide clinicians in the diagnosis and treatment of military trainees presenting with FRI.

TI Highly Realistic, Immersive Training for Navy Corpsmen: Preliminary Results SO MILITARY MEDICINE LA English DT Article AB Highly realistic, immersive training has been developed for Navy corpsmen based on the success of the Infantry Immersion Trainer. This new training is built around scenarios that are designed to depict real-life, operational situations. Each scenario used in the training includes sights, sounds, smells, and distractions to simulate realistic and challenging combat situations. The primary objective of this study was to assess corpsmen participants' satisfaction with highly realistic training. The study sample consisted of 434 male Navy service members attending Field Medical Training Battalion-West, Camp Pendleton, California. Corpsmen participants completed surveys after receiving the training. Participants expressed high levels of satisfaction with the training overall and with several specific elements of the training. The element of the training that the corpsmen rated the highest was the use of live actors. The vast majority of the participants reported that the training had increased their overall confidence about being successful corpsmen and had strengthened their confidence in their ability to provide care under pressure. Additional research should extend highly realistic training to other military medical provider populations.

The impact damage was in the form of craters, matrix/fiber tow breakage, compaction of the material, delamination and cone cracks, and their occurrence and degree depended on both impact velocity and type of target supports. The partial support resulted in significant damage with increasing impact velocity, accompanying substantial strength degradation. The presence of tensile stress and presumably stress wave interaction at the backside of a target could have been responsible for greater impact damage in partial support. Although the CMC targets impacted at 340m/s were on the verge of being penetrated, the targets still survived catastrophic failure retaining about 68% of the as-received strength, indicative of relatively superior FOD resistance as compared to monolithic ceramic counterparts. A quasi-static analysis of impact force prediction was made based on the energy balance principle and was validated indirectly using the experimental data on frontal impact damage size.

For mode-I cracks in the I-beam, the computed SIFs by using the SGBEM-FEM Alternating Method are in very good agreement with available empirical solutions. The predicted fatigue life of cracked I-beams agrees well with experimental observations in the open literature. For mixed-mode cracks in the web or in the flange of the I-beams, no analytical or empirical solutions are available in the literature. Thus mixed-mode SIFs for mixed-mode web and flange cracks are presented, and non-planar fatigue growth simulations are given, as benchmark examples for future studies. Moreover, because very minimal efforts of preprocessing and very small computational burden are needed, the current SGBEM-FEM Alternating Method is very suitable for fracture and fatigue analyses of 3D structures such as I-beams.

In this work, a multi-scale micromechanics based finite element framework is used to predict, and understand the effect of microstructure on the tensile deformation behavior, including progressive damage and failure, of ceramic fiber and fabric reinforced MMCs. A hierarchal approach is implemented in which a micro-scale model is used to determine the transversely isotropic elasto-plastic mechanical behavior of unidirectional fiber reinforced MMC based on the properties of an aluminum alloy matrix, individual ceramic fibers, and the fiber-matrix interface. The validated transversely isotropic constitutive behavior is then input into a unit cell model for a woven fabric MMC consisting of unidirectional MMC tows in an aluminum matrix. Parallel experimental tensile testing and characterization of fracture mechanisms are used to validate our model for unidirectional and 2D weave fabric MMC. Cohesive zones are used to model the interfacial properties at both scales and we are able to quantify the contribution of various deformation and damage mechanisms such as ductile matrix failure, interfacial decohesion, transverse plasticity, and axial fiber fracture to the overall mechanical response of the MMC. It was found that interfacial debonding contributes significantly to the inelastic response of unidirectional and woven fabric MMC and that experimental data are relatively well reproduced by a model that assumes a weak interfacial debonding cohesive law (maximum allowable interface stresses on the order of 100 MPa and total work of decohesion = 75 J/m(2)).

In both cases, dye evolved into a series of rolls with their major axes approximately aligned with the wind and/or near-surface current. In both cases, roll spacing was also of order 5-10 times the mixed layer depth, considerably larger than the 1-2 aspect ratio expected for Langmuir cells. Numerical large-eddy simulations under similar forcing showed similar features, even without Stokes drift forcing. In one case, inertial shear driven by light winds induced large aspect ratio large-eddy circulation. In the second, a preexisting lateral mixed layer density gradient provided the dominant forcing. In both cases, the growth of the large-eddy structures and the strength of the resulting dispersion were highly dependent on the type of forcing.

These are qualitatively distinct superconductors due to their energy-gap symmetries, d-wave (l = 2), i-wave (l = 6) and s-wave (l = 0), respectively. The calculations are compared with previously published IMD and surface-resistance measurements of impurity-doped YBCO and Nb. The agreement between the data and fitted calculations is excellent in all cases. In the absence of IMD and surface-resistance measurements for doped MgB2, we present representative predictions. The calculations are based on a Green's-function approach that yields analytical expressions for the penetration depth and the nonlinear kernel in the constitutive relation. This penetration-depth expression reproduces the measured T-2 low-temperature variation for doped superconductors and the surface-resistance reduction over that of the pure material. Regarding the IMD in superconductors with a nodal energy gap, the effect of doping is to enhance its magnitude and suppress its low-temperature 1/T-2 divergence predicted by the nonlinear Meissner effect.

Lofthouse, Andrew Kraft, Neal TI Dynamic Store Release of Ice Models from a Cavity into Mach 2.9 Flow SO JOURNAL OF AIRCRAFT LA English DT Article; Proceedings Paper CT 51st AIAA Aerospace Sciences Meeting and Exhibit Including the New Horizons Forum and Aerospace Exposition CY JAN 06-11, 2013 CL Grapevine, TX SP AIAA AB An investigation was conducted into store separation from a cavity in a Mach 2.94 freestream using both experimental and computational methods. Both approaches used an open cavity with a length-to-depth ratio of 4.5, and for the sake of simplicity, release of a spherical model was analyzed. The experimental process used a piezoresistive pressure transducer to collect the time-varying content of the pressure signal, while schlieren visualization and high-speed photography capture the dynamic response of a store released from the cavity. Computationally, the OVERFLOW solver was applied with higher-order numerical methods, Chimera grids, and the delayed detached-eddy simulation/ shear-stress transport hybrid turbulence model. Tests were performed in a blow downtunnel exhausting to a vacuum, which enabled robust control of the total pressure, and computational conditions were selected to match the experiment. The studies demonstrated that the shock wave formed on the bottom surface of the sphere led to the loss of vertical momentum for the sphere and, subsequently, its ascent back into the cavity for all but the lowest stagnation pressure conditions. Vortex-generating spoiler devices and an Mk-82 ice model were also experimentally tested to determine their effect, and the spoiler increased the vertical displacement of the store during separation, as expected.

In the U.S. shipbuilding industry, improvements to shipbuilding facilities and processing technology have not kept pace with the rate of change in ship design. Additionally, new designs using thinner steels are subject to legacy weld-sizing criteria, which may inappropriately size welds on lightweight materials. These two factors result in widespread overwelding, causing severe plate buckling in naval vessels during construction. The problem of overwelding has two distinct sources: 1) the weld-sizing methods developed in the 1980s are still used in most shipbuilding specifications regardless of ship class. This prevents the incentive of application of latest technologies that can make strong, precision fillet welds for modern lightweight thin steel naval surface combatants; and 2) shipyard welders tend to make welds even larger than design requirements to satisfy naval production specifications, which do not allow for any undersized welds. On average, production welds are 3 mm larger than design, which can more than double the heat input and distortion caused by welding. The approach to the solution of this overwelding problem will be described in detail in this article: 1) develop appropriate weld-sizing criteria for thin plate structures; this can be facilitated by numerical modeling to ensure adequate static shear, tensile, bending, fatigue, and dynamic impact capacity of structural welds; and 2) perform a robust designed experiment to establish confidence that small weld sizes can provide necessary performance and strength to meet the design service life of the vessel and provide data to NAVSEA technical warrant holders to support the implementation of an underweld tolerance for ship production to prevent overwelding.

TI Structural health monitoring-based methodologies for managing uncertainty in aircraft structural life assessment SO STRUCTURAL HEALTH MONITORING-AN INTERNATIONAL JOURNAL LA English DT Article DE Structural health monitoring; rotorcraft; composites; wide-area inspection; impact identification; uncertainty management; aircraft maintenance; risk reduction ID STIFFENED COMPOSITE PANELS; IMPACT IDENTIFICATION; PIEZOELECTRIC SENSORS; LOCATION; SYSTEM AB Aircraft maintenance approaches that rely on only scheduled inspections have an intrinsic amount of uncertainty and risk because intervals do not reflect the loading and damage history of individual aircraft. This risk is more pronounced in composite aircraft, because damage is often not visually apparent. This work presents two case studies of complementary structural health monitoring methods that are designed to reduce the risk in aircraft maintenance, as well as the cost of frequent, lengthy inspections. The first is an impact identification system which is capable of locating impacts to a full-scale fuselage using only three sensors. This impact identification method is able to quantify the severity of impacts, allowing maintenance personnel to focus inspections on areas that have sustained frequent and/or high-amplitude impacts. Using this method, over 97% of impacts to a heavy-lift helicopter fuselage are located within 9 in of the true impact location. The second case study details the development of a noncontact wide-area inspection method, which has the potential to reduce inspection times and uncertainty as compared to labor-intensive inspection methods such as coin tap testing. This inspection method exploits the nonlinear forced vibration characteristics of damaged areas through surface velocity measurements acquired by a scanning laser vibrometer. By comparing the structure's response to forcing functions of differing magnitudes, the local nonlinear characteristics of damage are identified. This automated inspection method is shown to be effective in locating subsurface damage in composite helicopter panels and has the potential to reduce both labor costs and damage detection uncertainty.

TI A Population Pharmacokinetic Modeling Approach Shows that Serum Penicillin G Concentrations Are Below Inhibitory Concentrations by Two Weeks after Benzathine Penicillin G Injection in the Majority of Young Adults SO ANTIMICROBIAL AGENTS AND CHEMOTHERAPY LA English DT Article ID A STREPTOCOCCAL PHARYNGITIS; RHEUMATIC-FEVER; VITRO SUSCEPTIBILITY; US ARMY; CHILDREN; ANTIBIOTICS; METAANALYSIS; PROPHYLAXIS; FAMILIES; BURDEN AB Serum penicillin G falls to low levels 2 weeks after injection as benzathine penicillin G (BPG) in young adults. Using Pmetrics and previously reported penicillin G pharmacokinetic data after 1.2 million units were given as BPG to 329 male military recruits, here we develop the first reported population pharmacokinetic model of penicillin G after BPG injection. We simulated time-concentration profiles over a broad range of pediatric and adult weights after alternative doses and dose frequencies to predict the probability of maintaining serum penicillin G concentrations of >0.02 mg/liter, a proposed protective threshold against group A Streptococcus pyogenes ( GAS). The final population model included linear absorption into a central compartment, distribution to and from a peripheral compartment, and linear elimination from the central compartment, with allometrically scaled volumes and rate constants. With 1.2 million units of BPG given intramuscularly every 4 weeks in four total doses, only 23.2% of 5,000 simulated patients maintained serum penicillin G trough concentrations of >0.02 mg/liter 4 weeks after the last dose. When the doses were 1.8 million units and 2.4 million units, the percentages were 30.2% and 40.7%, respectively. With repeated dosing of 1.2 million units every 3 weeks and every 2 weeks for 4 doses, the percentages of simulated patients with a penicillin G trough concentration of >0.02 mg/liter were 37.8% and 65.2%, respectively. Our simulations support recommendations for more frequent rather than higher BPG doses to prevent recurrent rheumatic heart disease in areas of high GAS prevalence or during outbreaks.

TI Deployment-Related Depression Screening, 2001-2008 Comparing Clinical Versus Research Surveys SO AMERICAN JOURNAL OF PREVENTIVE MEDICINE LA English DT Article ID POSTTRAUMATIC-STRESS-DISORDER; MILITARY SERVICE MEMBERS; HEALTH-CARE UTILIZATION; MILLENNIUM COHORT; US MILITARY; SMALLPOX VACCINATION; COMBAT DEPLOYMENT; ENROLLMENT; IMPACT; AFGHANISTAN AB Background: Potential adverse mental health effects of deployment, including depression, are an ongoing concern. Although a previous study assessed under-reporting of depression on post-deployment health assessments compared to anonymous surveys, those results were not examined at the individual level to identify demographic or military factors that may be associated with unwillingness to report depression symptoms. Purpose: To compare self-reported depression symptoms on post-deployment health assessments with responses to the same depression questions on a research survey. Methods: This cross-sectional study analyzed depression screening responses from 2001 to 2008 from participants of the Millennium Cohort Study, a longitudinal military cohort study, who completed a post-deployment health assessment within 30 days of a research survey. Kappa statistics and percent positive and negative agreement were calculated. Demographic and military characteristics associated with discordant screening results were examined. Initial analyses were performed in 2011, with additional analyses in 2013. Results: Moderate agreement (kappa=0.464) was observed between paired survey responses. A higher proportion of active duty members, the unmarried, and new accessions into military service endorsed depression symptoms on the research survey but not the military-linked survey. In stratified analyses, agreement was higher in Reserve/National Guard members than active duty (kappa=0.561 vs 0.409). New active duty accessions showed lower agreement (kappa=0.388), as did unmarried active duty participants (kappa=0.304). Conclusions: Deployment health surveys are important tools for identifying returning service members experiencing depression symptoms. However, these findings suggest that ongoing stigma and barriers to appropriate follow-up mental health care remain to be addressed in the military setting.

We assessed the effect of hepatitis B virus (HBV) and hepatitis C virus (HCV) co-infection on HIV outcomes in patients in China. Methods We did a nationwide retrospective observational cohort study with data from the China National Free Antiretroviral Treatment Program from 2010-11. Patients older than 18 years starting standard antiretroviral therapy for HIV who had tested positive for HBV and HCV were followed up to Dec 31, 2012. We used Kaplan-Meier analysis and Cox proportional hazard models to evaluate survival, and logistic regression models to estimate virological failure, immunological response, and retention in care. Findings 33 861 patients with HIV met eligibility criteria. 2958 (8.7%) participants had HBV co-infection, 6149 (18.2%) had HCV co-infection, and 1114 (3.3%) had triple infection. All-cause mortality was higher in participants with triple infection (adjusted hazard ratio 1.90, 95% CI 1.53-2.37) and HCV co-infection (1.46, 1.25-1.70) than in those with HIV only, but not in those with HBV co-infection (1.06, 0.89-1.26). People with triple infection were also more likely to have virological failure (adjusted odds ratio [OR] 1.26, 95% CI 1.02-1.56) than were those with HIV only, whereas the difference was not significant for those with HBV co-infection (0.93, 0.80-1.10) or HCV co-infection (1.10, 0.97-1.26). No co-infection was significantly associated with a difference in CD4 cell count after 1 year of treatment. Loss to follow-up was more common among participants with triple infection (OR 1-37, 95% CI 1.16-1.62) and HCV co-infection (1.30, 1.17-1.45), but not HBV co-infection (0.93, 0.82-1.05), than among those with HIV only. Interpretation Screening for viral hepatitis is important in individuals diagnosed as HIV positive. Effective management for viral hepatitis should be integrated into HIV treatment programmes. Long-term data are needed about the effect of hepatitis co-infection on HIV disease progression.

While patients with either PTSD or mTBI share abnormal activation of multiple frontal brain areas, anterior cingulate cortex (ACC) activity during inhibitory processing may be particularly affected by PTSD. To further test this hypothesis, we recorded electroencephalography from 32 combat veterans with mTBI-17 of whom were also comorbid for PTSD (mTBI+PTSD) and 15 without PTSD (mTBI-only). Subjects performed the Stop Task, a validated inhibitory control task requiring inhibition of initiated motor responses. We observed a larger inhibitory processing eventrelated potential (ERP) in veterans with mTBI+PTSD, including greater N200 negativity. Furthermore, greater N200 negativity correlated with greater PTSD severity. This correlation was most dependent on contributions from the dorsal ACC. Support vector machine analysis demonstrated that N200 and P300 amplitudes objectively classified veterans into mTBI-only or mTBI+PTSD groups with 79.4% accuracy. Our results support a model where, in combat veterans with mTBI, larger ERPs from cingulate areas are associated with greater PTSD severity and likely related to difficulty controlling ongoing brain processes, including trauma-related thoughts and feelings.

TI High Strain-Rate Response of Spiropyran Mechanophores in PMMA SO JOURNAL OF POLYMER SCIENCE PART B-POLYMER PHYSICS LA English DT Article DE compression; dyes/pigments; failure; fluorescence; impact resistance; mechanical properties; sensors ID POLYMER MECHANOCHEMISTRY; DYNAMIC FRACTURE; FORCE; ACTIVATION; STRESS; COPOLYMERS AB We report the high strain-rate response of a spiropyran (SP) mechanophore in poly(methylmethacrylate). Previous work on this system has demonstrated a reversible bond scission in the SP under local tensile force, converting it to a fluorescent merocyanine form. A Hopkinson bar was used to apply fast compressive loads at rates from 10(2) to 10(4) s(-1), resulting in significant activation of the SP near fracture surfaces. However, comparison with a similar thermochromic SP reveals that much of the observed activation likely arises from thermal effects during high-rate fracture. These results show the importance of a thermally active control system in distinguishing mechanochromic response during high-rate loading. Microscale fluorescence mapping of the fracture surfaces using a confocal Raman microspectrometer suggests that some distinct mechanical activation may be occurring in craze-like regions during fibril rupture. The thermal response of the SP is useful in its own right for characterizing plastic heating regions during dynamic fracture. Published 2014.

TI Dramatic Decline of Respiratory Illness Among US Military Recruits After the Renewed Use of Adenovirus Vaccines SO CLINICAL INFECTIOUS DISEASES LA English DT Article DE adenovirus; febrile respiratory illness; military; surveillance; vaccine ID COST-EFFECTIVENESS; TRAINING FACILITY; OUTBREAK; DISEASE; TYPE-4; TRAINEES; REEMERGENCE; VACCINATION; INFECTIONS; CAMP AB Background. In late 2011, after a 12-year hiatus, oral vaccines against adenovirus types 4 (Ad4) and 7 (Ad7) were again produced and administered to US military recruits. This study examined the impact of the new adenovirus vaccines on febrile respiratory illness (FRI) and adenovirus rates and investigated if new serotypes emerged. FRI rates and their associated hospitalizations had markedly risen since vaccine production ceased in 1999. Methods. From 1996 to 2013, the Naval Health Research Center conducted FRI surveillance at 8 military recruit training centers in the United States. During this period, 58 103 FRI pharyngeal swab specimens were studied, yielding 37 048 adenovirus-positive cases, among which 64% were typed. Results. During the 2 years after reintroduction of the vaccines, military trainees experienced a 100-fold decline in adenovirus disease burden (from 5.8 to 0.02 cases per 1000 person-weeks, P < .0001), without evidence that vaccine pressure had increased the impact of adenovirus types other than Ad4 and Ad7. Although the percentage of type 14 increased following reintroduction of the vaccination, the actual number of cases decreased. We estimate that the vaccines prevent approximately 1 death, 1100-2700 hospitalizations, and 13 000 febrile adenovirus cases each year among the trainees. Conclusions. These data strongly support the continued production and use of Ad4 and Ad7 vaccines in controlling FRI among US military trainees. Continued surveillance for emerging adenovirus subtypes is warranted.

TI Mechanical yield of the lumbar annulus: a possible contributor to instability SO JOURNAL OF NEUROSURGERY-SPINE LA English DT Article DE biomechanics; annulus fibrosus; mechanical yield; instability; lumbar spine ID TENSILE PROPERTIES; ANULUS FIBROSUS; DISC DEGENERATION; BEHAVIOR; INJURY; SPINE; SPONDYLOLISTHESIS; FLEXIBILITY; JOINT; SITE AB Object. Segmental instability in the lumbar spine can result from a number of mechanisms including intervertebral disc degeneration and facet joint degradation. Under traumatic circumstances, elevated loading may lead to mechanical yield of the annular fibers, which can decrease load-carrying capacity and contribute to instability. The purpose of this study was to quantify the biomechanics of intervertebral annular yield during tensile loading with respect to spinal level and anatomical region within the intervertebral disc. Methods. This laboratory-based study incorporated isolated lumbar spine annular specimens from younger and normal or mildly degenerated intervertebral discs. Specimens were quasi-statically distracted to failure in an environmentally controlled chamber. Stress and strain associated with yield and ultimate failure were quantified, as was stiffness in the elastic and postyield regions. Analysis of variance was used to determine statistically significant differences based on lumbar spine level, radial position, and anatomical region of the disc. Results. Annular specimens demonstrated a nonlinear response consisting of the following: toe region, linear elastic region, yield point, postyield region, and ultimate failure point. Regional dependency was identified between deep and superficial fibers. Mechanical yield was evident prior to ultimate failure in 98% of the specimens and occurred at approximately 80% and 74% of the stress and strain, respectively, to ultimate failure. Fiber modulus decreased by 34% following yield. Conclusions. Data in this study demonstrated that yielding of intervertebral disc fibers occurs relatively early in the mechanical response of the tissues and that stiffness is considerably decreased following yield. Therefore, yielding of annular fibers may result in decreased segmental stability, contributing to accelerated degeneration of bony components and possible idiopathic pain.

TI Injury-Reduction Effectiveness of Prescribing Running Shoes on the Basis of Foot Arch Height: Summary of Military Investigations SO JOURNAL OF ORTHOPAEDIC & SPORTS PHYSICAL THERAPY LA English DT Article DE footprints; foot type; pronation ID PLANTAR SHAPE; RUNNERS; MOTION; MECHANICS; FORCES; LEG AB STUDY DESIGN: Secondary analysis of 3 randomized controlled trials. OBJECTIVE: Analysis of studies that examined whether prescribing running shoes on the basis of foot arch height influenced injury risk during military basic training. BACKGROUND: Prior to 2007, running magazines and running-shoe companies suggested that imprints of the bottom of the feet (plantar shape) could be used as an indication of foot arch height and that this could be used to select individually appropriate types of running shoes. METHODS: Similar studies were conducted in US Army (2168 men, 951 women), Air Force (1955 men, 718 women), and Marine Corps (840 men, 571 women) basic training. After foot examinations, recruits were randomized to either an experimental or a control group. Recruits in the experimental group selected or were assigned motion-control, stability, or cushioned shoes to match their plantar shape, which represented a low, medium, or high foot arch, respectively. The control group received a stability shoe regardless of plantar shape. Injuries during basic training were assessed from outpatient medical records. RESULTS: Meta-analyses that pooled results of the 3 investigations showed little difference between the experimental and control groups in the injury rate (injuries per 1000 person-days) for either men (Summary rate ratio = 0.97; 95% confidence interval [CI]: 0.88, 1.06) or women (summary rate ratio = 0.97; 95% CI: 0.85, 1.08). When injury rates for specific types of running shoes were compared, there were no differences. CONCLUSION: Selecting running shoes based on arch height had little influence on injury risk in military basic training.

SO CLINICAL ORTHOPAEDICS AND RELATED RESEARCH LA English DT Article ID TRANSTIBIAL AMPUTATION; AMPUTEES; WALKING; LEVEL AB Two surgical techniques for performing a transtibial amputation include a traditional approach and a bone bridge approach. To date, there is no conclusive evidence of superiority of either technique in terms of temporal-spatial, kinetic, and mechanical work parameters. We sought to compare instrumented three-dimensional gait parameters and mechanical work measurements of patients who had undergone a traditional or bone bridge amputation at the transtibial level. Residual limb length and its effect on those functional outcomes was a secondary interest irrespective of amputation type. This retrospective comparative study included 14 active-duty military men with a mean age of 25 years (range, 20-28 years). Comparisons were made between seven patients with traditional and seven patients with bone bridge amputations at the transtibial level. The patients walked at self-selected and fast paces while three-dimensional gait analysis data were collected and comparisons were made between patients with the two amputation types as well as by length of the residual limb. With the numbers available, we observed no differences between the two surgical groups at either speed for the temporal-spatial parameters or mechanical work metrics. However, the bone bridge group did demonstrate greater rolloff vertical ground reaction force during the fast walking condition with a median 1.02% of body weight compared with 0.94% (p = 0.046), which suggests a more stable platform in terminal stance. When the two groups were combined into one to test the effect of residual limb length, the linear regression resulted in an R-2 value of 0.419 (p = 0.012), in which patients with longer residual limbs had improved F3 force values during self-selected walking. Overall, limited functional differences were found between the two groups in this small pilot study, so a superior surgical technique could not be determined; whereas our limited sample size prevents a firm conclusion of no difference, our data can be considered hypothesis-generating for future, larger studies. Although some evidence indicated that patients with a bone bridge have improved loading at higher speeds, a regression of all patients walking at self-selected speed indicates that as residual limb length increases, loading increases regardless of amputation type. Thus, our data suggest it is important to preserve residual limb length to allow for improved loading in terminal stance. Level III, therapeutic study.

TI Task-specific Fall Prevention Training Is Effective for Warfighters With Transtibial Amputations SO CLINICAL ORTHOPAEDICS AND RELATED RESEARCH LA English DT Article ID LOWER-LIMB AMPUTATION; TRIP-RELATED FALLS; OLDER-ADULTS; BALANCE CONFIDENCE; INPATIENT REHABILITATION; STEPPING RESPONSES; STANDING BALANCE; RISK-FACTORS; MOTOR SKILL; AMPUTEES AB Key factors limiting patients with lower extremity amputations to achieve maximal functional capabilities are falls and fear of falling. A task-specific fall prevention training program has successfully reduced prospectively recorded trip-related falls that occur in the community by the elderly. However, this program has not been tested in amputees. In a cohort of unilateral transtibial amputees, we aimed to assess effectiveness of a falls prevention training program by (1) quantifying improvements in trunk control; (2) measuring responses to a standardized perturbation; and (3) demonstrating retention at 3 and 6 months after training. Second, we collected patient-reported outcomes for balance confidence and falls control. Fourteen male military service members (26 +/- A 3 years) with unilateral transtibial amputations and who had been walking without an assistive device for a median of 10 months (range, 2-106 months) were recruited to participate in this prospective cohort study. The training program used a microprocessor-controlled treadmill designed to deliver task-specific postural perturbations that simulated a trip. The training consisted of six 30-minute sessions delivered over a 2-week period, during which task difficulty, including perturbation magnitude, increased as the patient's ability progressed. Training effectiveness was assessed using a perturbation test in an immersive virtual environment. The key outcome variables were peak trunk flexion and velocity, because trunk kinematics at the recovery step have been shown to be a determinant of fall likelihood. The patient-reported outcomes were also collected using questionnaires. The effectiveness of the rehabilitation program was also assessed by collecting data before perturbation training and comparing the key outcome parameters with those measured immediately after perturbation training (0 months) as well as both 3 and 6 months posttraining. Mean trunk flexion angle and velocity significantly improved after participating in the training program. The prosthetic limb trunk flexion angle improved from pretraining (42A degrees; 95% confidence interval [CI], 38A degrees-47A degrees) to after training (31A degrees; 95% CI, 25A degrees-37A degrees; p < 0.001). Likewise, the trunk flexion velocity improved from pretraining (187A degrees/sec; 95% CI, 166A degrees-209A degrees) to after training (143A degrees/sec; 95% CI, 119A degrees-167A degrees; p < 0.004). The results display a significant side-to-side difference for peak trunk flexion angle (p = 0.01) with perturbations of the prosthetic limb resulting in higher peak angles. Prosthetic limb trips also exhibited significantly greater peak trunk flexion velocity compared with trips of the prosthetic limb (p = 0.005). These changes were maintained up to 6 months after the training. The peak trunk flexion angle of the subjects when the prosthetic limb was perturbed had a mean of 31A degrees (95% CI, 25A degrees-37A degrees) at 0 month, 32A degrees (95% CI, 28A degrees-37A degrees) at 3 months, and 30A degrees (95% CI, 25A degrees-34A degrees) at 6 months. Likewise, the peak trunk flexion velocity for the prosthetic limb was a mean of 143A degrees/sec (95% CI, 118A degrees-167A degrees) at 0 months, 143A degrees/sec (95% CI, 126A degrees-159A degrees) at 3 months, and 132A degrees (95% CI, 115A degrees-149A degrees) at 6 months. The peak trunk flexion angle when the nonprosthetic limb was perturbed had a mean of 22A degrees (95% CI, 18A degrees-24A degrees) at 0 months, a mean of 26A degrees (95% CI, 20A degrees-32A degrees) at 3 months, and a mean of 23A degrees (95% CI, 19A degrees-28A degrees) at 6 months. The peak trunk flexion velocity for the nonprosthetic limb had a mean of 85A degrees/sec (95% CI, 71A degrees-98A degrees) at 0 months, a mean of 96A degrees (95% CI, 68A degrees-124A degrees) at 3 months, and 87A degrees/sec (95% CI, 68A degrees-105A degrees) at 6 months. There were no significant changes in the peak trunk flexion angle (p = 0.16) or peak trunk flexion velocity (p = 0.35) over time after the training ended. The skill retention was present when either the prosthetic or nonprosthetic limb was perturbed. There were side-to-side differences in the trunk flexion angle (p = 0.038) and trunk flexion velocity (p = 0.004). Perturbations of the prosthetic side resulted in larger trunk flexion and higher trunk flexion velocities. Subjects prospectively reported decreased stumbles, semicontrolled falls, and uncontrolled falls. These results indicate that task-specific fall prevention training is an effective rehabilitation method to reduce falls in persons with lower extremity transtibial amputations.

The damage is termed foreign object damage (FOD) and results in various issues to coatings as well as to substrates, from plastic impression to delamination to spallation to cracking, depending on the severity of impact. The FOD experiments were conducted utilizing a ballistic impact gun for vane airfoil components coated with 220 mu m-thick, 7% yttria-stabilized zirconia (7YSZ) by electron beam physical vapor deposit (EB-PVD). The testing was performed with impact velocities ranging from 150 m/s to Mach 1 using 1.6-mm hardened chrome-steel ball projectiles. The resulting FOD was in the forms of impact impressions, cone cracking, and delamination of the coatings/substrates. Prediction of delamination crack size as a function of impact velocity was made based on an energy-balance approach through a quasistatic, first-order approximation. The prediction was in reasonable agreement with experimental data considering a presumable compaction of the TBCs upon impact. C1 [Choi, Sung R.; Wright, Jennifer M.; Faucett, D.

TI Relative cost-effectiveness of a norovirus vaccine in the deployed military setting compared to a vaccine against Campylobacter sp., ETEC, and Shigella sp. SO VACCINE LA English DT Article DE Economic analysis; Norovirus; Military ID VIRAL GASTROENTERITIS OUTBREAK; NORWALK VIRUS; PASSENGER BEHAVIORS; US MILITARY; DISEASE; DIARRHEA; IMPACT; PREVENTION; INFECTION; FORCES AB Norovirus (NoV) has been identified as a significant cause of acute gastrointestinal illness among deployed military troops. We conducted a cost-effectiveness analysis for the use of a NoV vaccine in the military using a previously developed model that evaluated vaccines for ETEC, Campylobacter, and Shigella for prevention of non-outbreak associated travelers' diarrhea. Under conservative assumptions, acquisition of a NoV vaccine by the Department of Defense is estimated to result in a cost-effectiveness ratio per duty day lost to illness (CERDDL) of $1344 compared to a CERDDL of $776, $800, and $1275 for ETEC, Campylobacter sp., and Shigella sp., respectively compared to current management strategies. The absolute value of avoiding a duty day lost is likely to vary under different scenarios, and further study is needed to evaluate how improved diagnostics and prevention of outbreaks may impact the relative value of this vaccine. Overall, this study demonstrates the utility of a previously established evidence-based decision tool for prioritization of vaccine acquisition in an important target population.

TI High Rate of A(H1N1)pdm09 Infections among Rural Thai Villagers, 2009-2010 SO PLOS ONE LA English DT Article ID A H1N1 VIRUS; APRIL-MAY 2009; NEW-YORK-CITY; INFLUENZA-A; PANDEMIC INFLUENZA; HOUSEHOLD TRANSMISSION; CLINICAL-DIAGNOSIS; SEASONAL INFLUENZA; OUTBREAK; ANTIBODY AB Background: Pandemic influenza A(H1N1)pdm09 emerged in Thailand in 2009. A prospective longitudinal adult cohort and household transmission study of influenza-like illness (ILI) was ongoing in rural Thailand at the time of emergence. Symptomatic and subclinical A(H1N1)pdm09 infection rates in the cohort and among household members were evaluated. Methods: A cohort of 800 Thai adults underwent active community-based surveillance for ILI from 2008-2010. Acute respiratory samples from ILI episodes were tested for A(H1N1)pdm09 by qRT-PCR; acute and 60-day convalescent blood samples were tested by A(H1N1)pdm09 hemagglutination inhibition assay (HI). Enrollment, 12-month and 24-month followup blood samples were tested for A(H1N1)pdm09 seroconversion by HI. Household members of influenza A-infected cohort subjects with ILI were enrolled in household transmission investigations in which day 0 and 60 blood samples and acute respiratory samples were tested by either qRT-PCR or HI for A(H1N1)pdm09. Seroconversion between annual blood samples without A(H1N1)pdm09-positive ILI was considered as subclinical infection. Results: The 2-yr cumulative incidence of A(H1N1)pdm09 infection in the cohort in 2009/2010 was 10.8% (84/781) with an annual incidence of 1.2% in 2009 and 9.7% in 2010; 83.3% of infections were subclinical (50% in 2009 and 85.9% in 2010). The 2-yr cumulative incidence was lowest (5%) in adults born <= 1957. The A(H1N1) pdm09 secondary attack rate among household contacts was 47.2% (17/36); 47.1% of these infections were subclinical. The highest A(H1N1)pdm09 secondary attack rate among household contacts (70.6%, 12/17) occurred among children born between 1990 and 2003. Conclusion: Subclinical A(H1N1)pdm09 infections in Thai adults occurred frequently and accounted for a greater proportion of all A(H1N1)pdm09 infections than previously estimated. The role of subclinical infections in A(H1N1)pdm09 transmission has important implications in formulating strategies to predict and prevent the spread of A(H1N1)pdm09 and other influenza virus strains.

TI Assessing fuel-cell coolant flow fields with numerical models and infrared thermography SO INTERNATIONAL JOURNAL OF HYDROGEN ENERGY LA English DT Article DE Thermal management; IR thermography; Cooling channels; Visualization ID METALLIC BIPOLAR PLATES; COOLING PLATES; PEMFC STACK AB Proper thermal management is important to the successful operation and durability of proton exchange membrane fuel cell (PEMFC) systems. In liquid cooled fuel cell systems, the planar temperature distribution of the cell is largely controlled by the coolant flow field (CFF) design inside bipolar plates (BPPs). We characterize the temperature distribution of the coolant in two different CFF designs made out of Ti-6Al-4V titanium alloy by using infrared (IR) thermography and a coupled heat-transfer numerical model. Numerical models show that the two CFFs have nearly equivalent global heat transfer characteristics and temperature distributions but very different coolant flow characteristics; one design has uneven flow through parallel cooling channels and the other design has even flow through parallel cooling channels. These two designs are used to probe the capability of IR thermography to resolve subtle differences in temperature distribution in the CFFs. We find that the temperature distribution in CFFs measured using IR thermography matches the predicted numerical model results. We conclude that IR thermograph is a useful tool for characterizing CFFs because it can visualize local temperature differences caused by trapped bubbles in addition to the overall in-plane temperature distribution.

In this brief report, we examine the relationship between spontaneous and deliberate subtypes of dissociation, and objective military performance in Special Forces and non-Special Forces personnel enrolled in survival school. Inverse relationships between dissociation and military performance were observed in both Special Forces and general soldier subgroups. Military performance did not differ between spontaneous and deliberate dissociators, nor did it differ between those who appraised dissociative states as facilitative versus debilitative to stress coping. This study evolves our understanding of factors influencing human performance in the high-stakes survival context.

Understanding the impact of the recent conflicts on families is a national priority, however, most studies have examined spouses and children individually, rather than concurrently as families. The Department of Defense (DoD) has recently initiated the largest study of military families in US military history (the Millennium Cohort Family Study), which includes dyads of military service members and their spouses (n>10,000). This study includes US military families across the globe with planned follow-up for 21+ years to evaluate the impact of military experiences on families, including both during and after military service time. This review provides a comprehensive description of this landmark study including details on the research objectives, methodology, survey instrument, ancillary data sets, and analytic plans. The Millennium Cohort Family Study offers a unique opportunity to define the challenges that military families experience, and to advance the understanding of protective and vulnerability factors for designing training and treatment programs that will benefit military families today and into the future.

Bacillus thuringiensis israelensis was applied at maximum label rate in a 232.26-m(2) field plot located in north-central Florida with containers placed at 2 heights (ground level and 1.52 m above ground) on stakes positioned 3.04, 6.09, 9.14, 12.19, and 15.24 m from the spray line. Results indicated that there was no significant (P > 0.05) difference in 24- and 48-h larval mortality between the 2 sprayers or between the 2 heights. There was significant difference (P < 0.05) among the 5 rows, with mortality continuously decreasing with increasing distance from sprayer. Both sprayers provided on average >70% larval mortality 3.04-9.14 m from the spray line, and <60% mortality at 12.19 and 15.24 m. The data suggest that the SR450 and Superhawk XP may be comparable sprayers for use with Bti to control mosquito larvae.

Gordon TI Methodology for Rotorcraft Brownout Mitigation Through Flight Path Optimization SO JOURNAL OF GUIDANCE CONTROL AND DYNAMICS LA English DT Article ID HELICOPTER BROWNOUT; WAKES AB A methodology is presented for the selection of approach-to-landing maneuvers that may result in improved brownout characteristics. The methodology is based upon a brownout metric that assesses the relative brownout cloud volume densities in critical regions of the pilot's field of view. The metric becomes the objective function of a procedure in which a typical visual approach profile is parameterized and optimized to minimize brownout in a representative landing maneuver. The optimization is constrained to avoid maneuvers that would be conducive to the onset of vortex ring state or would result in flight within the "avoid" regions of a typical helicopter height velocity diagram. The analysis uses a free-vortex wake model and simulates the dynamics of the dust particles immersed in the rotor downwash. The results show that the optimal approach trajectories affect the resulting flowfield, particularly the development of a ground vortex ahead of the rotor disk, which influences the rate of development, size, and volume density of the brownout cloud. The results are compared with prior experimental results, and potential operational interpretations of the outcomes are examined. C1 [Tritschler, John K.] Univ Maryland, College Pk, MD 20742 USA.

Little is known of neuroprotective-neurotrophic effects of DHEAS during stress exposure, either in men or women. This translational study was designed to examine neuroprotective-neurotrophic effects of DHEAS throughout intense stress exposure in healthy men and women. The study took place within a stressful 12-day military survival course. Utilizing a longitudinal cross-sectional repeated measures design, One hundred sixteen healthy active-duty military personnel (80% male) were studied before, during, and 24 h after the course. The dependent variable was the neurotrophin salivary nerve growth factor (sNGF). In terms of total hormone output, the effect of DHEAS on sNGF was mediated by testosterone. Unlike testosterone or cortisol, DHEAS reliably predicted sNGF at each time point, and change in DHEAS predicted change in sNGF across time points. Baseline DHEAS predicted total sNGF output across the stress trajectory. Consistent with preclinical as well as cross-sectional human research, this study demonstrates neuroprotective-neurotrophic effects of DHEAS in healthy men and women exposed to intense stress. Results are evaluated in relation to established criteria for causation. Published by Elsevier Inc.

TI Structural characterization of Bi2Te3 and Sb2Te3 as a function of temperature using neutron powder diffraction and extended X-ray absorption fine structure techniques SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID THERMOELECTRIC-MATERIALS; BISMUTH TELLURIDE; STRUCTURE SPECTRA; CRYSTAL-STRUCTURE; OPTIMIZATION; AMPLITUDE; IFEFFIT; ALLOYS; MERIT; FILMS AB The structure of Bi2Te3 (Seebeck coefficient Standard Reference Material (SRM (TM) 3451)) and the related phase Sb2Te3 have been characterized as a function of temperature using the neutron powder diffraction (NPD) and the extended X-ray absorption fine structure (EXAFS) techniques. The neutron structural studies were carried out from 20K to 300K for Bi2Te3 and from 10K to 298K for Sb2Te3. The EXAFS technique for studying the local structure of the two compounds was conducted from 19K to 298 K. Bi2Te3 and Sb2Te3 are isostructural, with a space group of R (3) over barm. The structure consists of repeated quintuple layers of atoms, Te2-M-Te1-M-Te2 (where M = Bi or Sb) stacking along the c-axis of the unit cell. EXAFS was used to examine the bond distances and static and thermal disorders for the first three shells of Bi2Te3 and Sb2Te3 as a function of temperature. The temperature dependencies of thermal disorders were analyzed using the Debye and Einstein models for lattice vibrations. The Debye and Einstein temperatures for the first two shells of Bi2Te3 are similar to those of Sb2Te3 within the uncertainty in the data. However, the Debye and Einstein temperatures for the third shell of Bi-Bi are significantly lower than those of the third shell of Sb-Sb. The Einstein temperature for the third shell is consistent with a soft phonon mode in both Bi2Te3 and Sb2Te3. The lower Einstein temperature of Bi-Bi relative to Sb-Sb is consistent with the lower value of thermal conductivity of Bi2Te3 relative to Sb2Te3. C1 [Mansour, A.

The self-consistency ensures that the spin and charge conservation laws are properly satisfied. We consider forward and angularly averaged conductances over a broad range of the strength of the exchange fields and F thicknesses, as the relative in-plane magnetization angle, phi, between the two ferromagnets varies. The f dependence of the self-consistent conductance curves in the trilayers can differ substantially from that obtained via a non-self-consistent approach. The zero-bias forward conductance peak exhibits, as phi varies, resonance effects intricately associated with particular combinations of the geometrical and material parameters. We find, when the magnetizations are noncollinear, signatures of the anomalous Andreev reflections in the subgap regions of the angularly averaged conductances. When F-1 is half metallic, the angularly averaged subgap conductance chiefly arises from anomalous Andreev reflection. The in-plane components of the spin current are strongly bias dependent, while the out-of-plane spin current component is only weakly dependent upon voltage. The components of the spin current aligned with the local exchange field of one of the F layers are conserved in that layer and in the S region, while they oscillate in the other layer. We compute the spin transfer torques, in connection with the oscillatory behavior of spin currents, and verify that the spin continuity equation is strictly obeyed in our method.

The influence of temperature on the viscosity of the uncured resin was measured to optimize the injection conditions for high resin infiltration into the delaminations. The repair efficiency of the resin was evaluated by varying the panel thickness and the method by which the delamination damage was created in the composite specimens. Ultrasonic scanning (C-scan), flash thermography images, and cross-section analysis of repaired panels revealed excellent resin infiltration into the damaged region. Evaluation of mechanical repair efficiency using both bending stiffness and in-plain compressive strength of the composite panels as the repair metrics showed values exceeding 100%.

Development of simple chemistry to exfoliate and intercalate graphite and graphite mimics in large quantities is required for numerous applications. To determine the macroscopic behavior of restacked, exfoliated bulk materials, a systematic approach is presented using a simple, redox-liquid sonication process along to obtain large quantities of 2D and 3D hexagonally layered graphite, molybdenum disulfide, and boron nitride, which are subsequently characterized to observe chemical and structural changes. For MoS2 sonicated with the antioxidant sodium bisulfite, results from Raman spectroscopy, X-ray diffraction, and electron microscopy indicate the presence of distorted phases from different polymorphs, and apparent nanotube structures in the bulk, restacked powder. Furthermore, using thermograviemtric analysis, the antioxidant enhances the resistance to oxidative degradation of MoS2, upon thermal treatment up to 900 degrees C. The addition of the ionic antioxidant decreased dispersion stability in non-polar solvent, suggesting decreased compatibility with non-polar systems. Using simple chemical methods, the ability to generate tailored multidimensional layered materials with unique macroscopic properties is critical for numerous applications, including electrical devices, reinforced polymer composites, lithium-ion capacitors, and chemical sensing.

Little is known of their combined effects, especially in high stress environments. This study evaluated distinct and combined effects of polymorphisms in the serotonin transporter (5HTTLPRL/S), glucocorticoid receptor (Bcl1C/G), and mineralocorticoid (-2C/G) receptor genes on adrenocortical and cardiovascular responses to intense, realistic stress. One hundred and forty four healthy, active-duty military men were studied before, during, and 24h after a stressful 12-day survival course. Dependent variables were cortisol, heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP). 5HTTLPR SS carriers revealed higher overall cortisol concentrations than L carriers (p =.022). 5HTTLPR L carriers demonstrated higher stress-induced HR than non-carriers (SS) yet rebounded to a lower recovery value (p =.026), while Bcl1 G carriers showed higher mean stress-induced HR than non-carriers (CC) (p =.047). For DBP, 5HTTLPR S carriers showed higher overall values than non-carriers (LL) (p =.043), Bcl1 GG were higher than C carriers (p =.039), and -2C/G G carriers exceeded non-carriers (CC) (p =.028). A "high" composite genotype group revealed substantially higher overall cortisol concentrations than a "low" composite genotype group (p < .001), as was the case for DBP (p =.037). This study revealed a synergistic effect of common polymorphisms on the acute stress response in healthy men. Pending additional study, these findings may have implications for drug discovery, gene therapy, and stress inoculation strategies. (C) 2014 Published by Elsevier B.V.

We conducted a prospective, longitudinal study among 350 HIV-infected adults attending a HIV clinic in San Diego, CA (USA) from January 2010 to December 2011 to examine both established and novel predictors of adherence, including religious practices and beliefs. Statistically significant (p < .05) variables identified in bivariate analyses were included in multivariate analyses predicting >= 90% adherence. Higher annual household income (p = .004) and religious affiliation (p = .031) were predictive of greater adherence. Participants who said their beliefs gave meaning to their lives, made them feel they had a connection with a higher being, were influential during their recovery, and helped them feel connected to humanity were more likely to be >= 90% adherent (p < .015). Conversely, participants who believed God created all things in the universe; that God will not turn his back on them; and those who regularly attended religious services, participated in religious rituals, and prayed and meditated to get in touch with God were less likely to be >= 90% adherent (p <= .025). Results indicate that a patient's religious beliefs and practices may predict medication adherence. Interventions should be designed to emphasize the use of positive religious coping strategies and address the adverse implications of religious fatalism.

TI Modifying Resilience Mechanisms in At-Risk Individuals: A Controlled Study of Mindfulness Training in Marines Preparing for Deployment SO AMERICAN JOURNAL OF PSYCHIATRY LA English DT Article ID COGNITIVE-BEHAVIORAL TREATMENT; FUNCTIONAL MAGNETIC-RESONANCE; IRRITABLE-BOWEL-SYNDROME; INTEROCEPTIVE EXPOSURE; INSULA ACTIVATION; PANIC DISORDER; ANXIETY; STRESS; EMOTION; MEDITATION AB Objective: Military deployment can have profound effects on physical and mental health. Few studies have examined whether interventions prior to deployment can improve mechanisms underlying resilience. Mindfulness-based techniques have been shown to aid recovery from stress and may affect brain-behavior relationships prior to deployment. The authors examined the effect of mindfulness training on resilience mechanisms in active-duty Marines preparing for deployment. Method: Eight Marine infantry platoons (N=281) were randomly selected. Four platoons were assigned to receive mindfulness training (N=147) and four were assigned to a training-as-usual control condition (N=134). Platoons were assessed at baseline, 8 weeks after baseline, and during. and after a stressful combat training session approximately 9 weeks after baseline. The mindfulness training condition was delivered in the form of 8 weeks of Mindfulness-Based Mind Fitness Training (MMFT), a program comprising 20 hours of classroom instruction plus daily homework exercise's. MM FT emphasizes interoceptive awareness, attentional control, and tolerance of present-moment experiences. The main outcome measures were heart rate, breathing rate, plasma neuropeptide Y concentration, score on the Response to Stressful Experiences Scale, and brain activation as measured by functional MRI. Results: Marines who received MMFT showed greater reactivity (heart rate [d=0.43]) and enhanced recovery (heart rate [d=0.67], breathing rate [d=0.93]) after stressful training; lower plasma neuropeptide Y concentration after stressful training (d=0.38); and attenuated blood-oxygen-level-dependent signal in the right insula and anterior cingulate. Conclusions: The results show that mechanisms related to stress recovery can be modified in healthy individuals prior to stress exposure, with important implications for evidence-based mental health research and treatment.

This peridomestic mosquito deposits eggs in natural and artificial containers. Container larval habitats tend to be cryptic and, therefore, difficult to reach by conventional insecticide treatments. We have developed an autodissemination station that transfers the insect growth regulator, pyriproxyfen, from the station to oviposition sites. Mosquitoes visiting the station become contaminated with an oil sticker followed by pyriproxyfen powder before exiting. RESULTS: In a room (31 m(3)) bioassay a single station consistently achieved 100% Ae. albopictus pupal mortality against 10 oviposition containers. In a greenhouse (200 m(3)) assay with two stations and 12 oviposition cups, 91.7% of the cups had been contaminated as shown, and 57.1% pupal mortality was recorded. Pyriproxyfen transfer was also detected by visualizing mosquito 'tarsal prints' using a fluorescent dye. CONCLUSIONS: The oil and pyriproxyfen powder dual-treatment station enhanced autodissemination efficacy by increasing toxicant attachment and retention on contaminated females. The autodissemination station offers a targeted, less environmentally damaging approach to manage cryptic container species.

TI Methane and carbon dioxide adsorption and diffusion in amorphous, metal-decorated nanoporous silica SO MOLECULAR SIMULATION LA English DT Article DE Grand canonical Monte Carlo simulation; spherosilicate; metal-decorated silica; physisorption ID ORGANIC FRAMEWORKS; MOLECULAR-DYNAMICS; BUILDING-BLOCK; SUSTAINABLE DEVELOPMENT; HYDROGEN; ENERGY; STORAGE; STATE; CO2; SILSESQUIOXANES AB The adsorptive and diffusive behaviour of methane and carbon dioxide in amorphous nanoporous adsorbents composed of spherosilicate building blocks, in which isolated metal sites have been distributed, is examined. The adsorbent contains cubic silicate building blocks (spherosilicate units: Si8O20), which are cross linked by SiCl2O2 bridges and decorated with either -OTiCl3 or -OSiMe3 groups of the other cube corners. The model structures were generated to correspond to experimentally synthesised materials, matching physical properties including density, surface area and accessible volume. It is shown that both methane and carbon dioxide adsorb via physisorption only in the modelled materials. Adsorption isotherms and energies at 300K for pressures up to 100bar were generated via molecular simulation. The maximum gravimetric capacity of CH4 is 16.9wt%, occurring at 300K and 97bar. The maximum gravimetric capacity of CO2 is 50.3wt%, occurring at 300K and 51.6bar. The best performing adsorbent was a low-density (high accessible volume) material with no -OTiCl3 groups. The presence of -OTiCl3 did not enhance physisorption even on a volumetric basis, and the high molecular weight of -OTiCl3 groups is a significant penalty on a gravimetric basis. Based on the pair correlation functions, the most favourable adsorption sites for both adsorbates are located in front of the faces of spherosilicate cubes. The self-diffusivity and activation energy for diffusion are also reported. C1 [Suraweera, Nethika S.] Univ Tennessee, Dept Chem & Biomol Engn, Knoxville, TN 37996 USA.

TI Modeling of steady-state convective cooling of cylindrical Li-ion cells SO JOURNAL OF POWER SOURCES LA English DT Article DE Lithium-ion batteries; Convective cooling; Thermal management; Safety; Thermal runaway ID THERMAL MANAGEMENT; LITHIUM BATTERIES; ELECTRODES; PACKS AB While Lithium-ion batteries have the potential to serve as an excellent means of energy storage, they suffer from several operational safety concerns. Temperature excursion beyond a specified limit for a Lithium-ion battery triggers a sequence of decomposition and release, which can preclude thermal runaway events and catastrophic failure. To optimize liquid or air-based convective cooling approaches, it is important to accurately model the thermal response of Lithium-ion cells to convective cooling, particularly in high-rate discharge applications where significant heat generation is expected. This paper presents closed-form analytical solutions for the steady-state temperature profile in a convectively cooled cylindrical Lithium-ion cell. These models account for the strongly anisotropic thermal conductivity of cylindrical Lithium-ion batteries due to the spirally wound electrode assembly. Model results are in excellent agreement with experimentally measured temperature rise in a thermal test cell. Results indicate that improvements in radial thermal conductivity and axial convective heat transfer coefficient may result in significant peak temperature reduction. Battery sizing optimization using the analytical model is discussed, indicating the dependence of thermal performance of the cell on its size and aspect ratio. Results presented in this paper may aid in accurate thermal design and thermal management of Lithium-ion batteries. (C) 2014 Elsevier B.V. All rights reserved. C1 [Shah, K.; Drake, S.

The HSR-MS steady state flux (J(ss)) was highly dependent on omega and D ranging from 10 to 433 L/m(2) hr (LMH). For every 100 rpm increase in omega, J(ss) increased on average by 26 LMH. The outer membrane third provided >= 50% of the total flow, with the inner third providing about 15%. The J(ss)-gamma relationship was extended to larger membranes (312 and 374 mm) and predicted that J(ss) increased by about 15% for each increase in size. Q(ss) was much more sensitive to increases in diameter and corresponding surface area - Q increased by 45% for D=267 mm -> 312 mm and 65% increased for D=312 mm -> 374 mm (approximate to 1% increase in Q per mm increase in diameter). Collectively, the results show that larger discs, rotated at lower rotations, can produce similar or greater Q compared to smaller discs rotating faster (C) 2014 Published by Elsevier B.V.

Grain growth occurs above 300 degrees C with significant growth at similar to 400 degrees C. Grain growth continued upon heating to 450 degrees C; the grain size did not significantly increase when the temperature was held at 450 degrees C long term. In situ TEM revealed a duplex microstructure that was not fully recrystallized. The activation energy for grain growth was determined to be similar to 32 kJ/mol. The submicrometer grains produced by UIT offer improved resistance to fatigue and corrosion. The majority of sensitized 5456-H116 failures are sensitive to the material's surface properties and operational service temperature; the stability of the submicrometer grains in the UIT Al- Mg makes them more stable in practical operations where increase in the material temperature is an issue.

Though health behaviors are known to affect immunity and vaccine delivery modes utilize different immune processes, data regarding the preferred influenza vaccine type among adults endorsing specific health-related behaviors (alcohol use, tobacco use, and exercise level) are limited. Methods: The relative effectiveness of two currently available influenza vaccines were compared for prevention of influenza-like illness during 2 well-matched influenza seasons (2006/2007, 2008/2009) among US military personnel aged 18-49 years. Relative vaccine effectiveness was compared between those self-reporting and not reporting recent smoking history and potential alcohol problem, and by exercise level using Cox proportional hazard modeling adjusted for sociodemographic and military factors, geographic area, and other health behaviors. Results: 28,929 vaccination events and 3936 influenza-like illness events over both influenza seasons were studied. Of subjects, 27.5% were smokers, 7.7% had a potential alcohol-related problem, 10.5% reported minimal exercise, and 4.4% reported high exercise levels. Overall, the risk of influenza-like illness did not significantly differ between live attenuated and trivalent inactivated influenza vaccine recipients (hazard ratio, 0.98; 95% confidence interval, 0.90-1.06). In the final adjusted model, the relative effectiveness of the 2 vaccine types did not differ by smoking status (p = 0.10), alcohol status (p = 0.21), or activity level (p = 0.11). Conclusions: Live attenuated and trivalent inactivated influenza vaccines were similarly effective in preventing influenza-like illness among young adults and did not differ by health-related behavior status. Influenza vaccine efforts should continue to focus simply on delivering vaccine.

Formative work with the BDF found that scented condoms and military-inspired (camouflage) wrapper graphics were appealing to personnel. A non-randomized intervention study was implemented to determine whether condom wrapper graphics and scent improved condom use in the BDF. Four military sites were selected for participation. Two sites in the south received the intervention condom wrapped in a generic wrapper and two sites in the north received the intervention condom wrapped in a military-inspired wrapper; intervention condoms were either scented or unscented. Two hundred and eleven male soldiers who ever had sex, aged 18-30 years, and stationed at one of the selected sites consented to participate. Sexual activity and condom use were measured pre- and post-intervention using sexual behavior diaries. A condom use rate (CUR; frequency of protected sex divided by the total frequency of sex) was computed for each participant. Mean CURs significantly increased over time (85.7% baseline vs. 94.5% post-intervention). Adjusted odds of condom use over time were higher among participants who received the intervention condom packaged in the military wrapper compared with the generic wrapper. Adjusted odds of condom use were also higher for participants who reported using scented vs. unscented condoms. Providing scented condoms and condoms packaged in a miltiary-inspired wrapper may help increase condom use and reduce HIV infection among military personnel.

TI Longitudinal Assessment of Mental Disorders, Smoking, and Hazardous Drinking Among a Population-Based Cohort of US Service Members SO JOURNAL OF ADDICTION MEDICINE LA English DT Article DE alcohol drinking; cohort studies; mental disorders; military personnel; smoking ID POSTTRAUMATIC-STRESS-DISORDER; MILLENNIUM COHORT; MILITARY SERVICE; COMBAT DEPLOYMENT; HEALTH PROBLEMS; ALCOHOL-USE; PSYCHIATRIC-DISORDERS; PRIMARY-CARE; FOLLOW-UP; PRIME-MD AB Objectives: Combat exposure is known to increase the risk for mental disorders; however, less is known about the temporal relationship between mental disorders and alcohol misuse or smoking. To better understand these interrelationships, this study investigated mental disorders in association with hazardous drinking and cigarette smoking. Methods: Using data from a large population-based military cohort, standardized instruments were used to screen for posttraumatic stress disorder, depression, panic, and other anxiety syndromes. Self-reported use of cigarettes and hazardous drinking was also assessed. Subjects were classified as having "new-onset," "persistent," or " resolved" mental disorders and health risk behaviors on the basis of screening results from baseline to follow-up (n = 50,028). Multivariable logistic regression models were used to investigate temporal patterns between the development of mental disorders and the uptake of smoking or hazardous drinking. Results: The strongest associations of new-onset mental disorders were among those who newly reported smoking or hazardous drinking (odds ratio [OR], 1.82; 95% confidence interval [CI], 1.28-2.59 and OR, 2.49; 95% CI, 2.15-2.89, respectively), even after adjustment for combat deployment experience. In addition, persistent smokers and hazardous drinkers had elevated odds for developing a mental disorder at follow-up. Conclusions: This study demonstrates a positive association between the onset of mental disorders with the uptake of smoking and hazardous drinking and the likelihood that multiple temporal sequence patterns exist to explain the relationship between mental disorders and hazardous drinking and smoking. Clinical approaches to mitigate deployment-related mental disorders should include alcohol and tobacco-related assessments and interventions.

The outcome includes all International Classification of Diseases, 9th Revision codes related to injuries resulting from cumulative microtrauma (overuse injuries). The short survey asked about the subject's demographics, smoking habits, prior injuries sustained, physical activity level, self-perceived fitness, and (for women) menstrual history. From the survey, 4 questions established smoking behavior: smoked at least 100 cigarettes in lifetime, age smoked a whole cigarette for the first time, how many cigarettes smoked during the last 30 days, and how many cigarettes smoked per day during the last 30 days. None of the adjusted hazard ratios for the smoking questions were associated with an increased risk of overuse injury for either sex. Furthermore, this study did not find a significant association with respect to smoking and all injuries in either men or women. In conclusion, smoking does not appear to be an independent risk factor for overuse injury in either young men or women during 12 weeks of standardized military instruction.

This study was designed to quantify the prevalence and mental health correlates of sleep disruption among military personnel serving within a ground combat zone during Operation Enduring Freedom. This was a large, cross-sectional survey of active duty and reserve U.S. Navy personnel (N = 3,175). Self-reported sleep measures included total hours of sleep per day, total hours of sleep required to feel well-rested, difficulty falling asleep, and difficulty staying asleep. The survey also measured mental health symptoms, including post-traumatic stress symptoms, anxiety, and depression. Participants reported an average of 5.9 hours of sleep per day despite requiring on average 6.8 hours to feel well rested. More than half (56%) were classified as sleep deficient, and 67% reported 6 or fewer hours of sleep per day. Adjusted for covariates, individuals endorsing sleep disruption were at substantially elevated risk of meeting criteria for post-traumatic stress disorder, generalized anxiety disorder, and major depressive disorder. This study documents the prevalence of sleep disruption in a very large and difficult-to-access sample of military members serving in a combat zone, and details robust associations with mental health.

TI Military HIV Policy Assessment in Sub-Saharan Africa SO MILITARY MEDICINE LA English DT Article AB While HIV/AIDS continues to inflict a heavy toll on African militaries, the military commitment and leadership response has been inconsistent, as reflected by variable presence of a written my policy. The Department of Defense HIV/AIDS Prevention Program collaborates with most sub-Saharan military HIV/AIDS programs. In 2010, 28 invited countries (80%) completed a self-administered survey describing their program, including policy. Descriptive and nonparametric measures were calculated. The majority (57%) of respondents reported having a written military HIV policy. Of these, 86% included HIV testing, 88% required recruit testing, and 96% denied entry for those testing HIV-positive. Mandatory HIV testing was reported by 71%, occurring before deployments, peacekeeping missions, foreign training, and when clinically indicated. Southern African militaries were most likely to require HIV testing. The majority of militaries allowed deployment of HIV-positive personnel in-country, whereas few allowed foreign deployment. Most sub-Saharan militaries screen applicants for HIV and other diseases to determine duty fitness, resulting in near universal HIV negative recruit cohorts. No militaries discharge personnel from service if they acquire HIV. Legal challenges to military HIV policies may hinder finalization and dissemination of policies. Lack of HIV policies impedes routine testing and earlier care and treatment for HIV-infected personnel.

TI Predictors of Continued Problem Drinking and Substance Use Following Military Discharge SO JOURNAL OF STUDIES ON ALCOHOL AND DRUGS LA English DT Article ID POSTTRAUMATIC-STRESS-DISORDER; MENTAL-HEALTH PROBLEMS; ALCOHOL-USE; WAR VETERANS; COLLEGE-STUDENTS; GULF-WAR; IRAQ WAR; PTSD; AFGHANISTAN; DEPRESSION AB Objective: The goals of the present study were to (a) examine change in rates of problem alcohol/substance use among a sample of veterans between their last year of military service and their first year following separation, (b) identify predictors of continued problem use in the first year after separation, and (c) evaluate the hypothesis that avoidant coping, posttraumatic stress disorder (PTSD) symptoms, and chronic stress place individuals at particularly high risk for continued problem use. Method: Participants (N = 1,599) completed self-report measures before and during the year following separation. Participants who endorsed either having used more than intended or wanting or needing to cut down during the past year were considered to have problem use. Results: Of 742 participants reporting problem substance use at baseline, 42% reported continued problem substance use at follow-up ("persistors"). Persistors reported more trouble adjusting to civilian life, had a greater likelihood of driving while intoxicated, and had a greater likelihood of aggression. Multivariate analyses showed that avoidant coping score at baseline and higher PTSD symptom score and greater sensation seeking at follow up predicted continued problem use. Conclusions: Understanding risk factors for continued problem use is a prerequisite for targeted prevention of chronic problems and associated negative life consequences.

As part of a broad study to assess the efficacy of dengue vector control tools for the U.S. Military, two pesticide delivery systems (ultra-low volume [ULV] and thermal fog) were evaluated for their ability to provide immediate control of Ae. aegypti mosquitoes with a contact insecticide inside simulated urban structures. An insect growth regulator was also applied to determine how well each sprayer delivered lethal doses of active ingredient to indoor water containers for pupal control. Mortality of caged Ae. aegypti, pesticide droplet size, and droplet deposition were recorded after applications. In addition, larval and pupal mortality was measured from treated water samples for 4 wk after the applications. The ULV and the thermal fogger performed equally well in delivering lethal doses of adulticide throughout the structures. The ULV resulted in greater larval mortality and adult emergence inhibition in the water containers for a longer period than the thermal fogger. Therefore, the ULV technology is expected to be a better tool for sustained vector suppression when combined with an effective insect growth regulator. However, during a dengue outbreak, either delivery system should provide an immediate knockdown of vector populations that may lower the risk of infection and allow other suppression strategies to be implemented.

We evaluated anti-MenC antibody persistence in U.S. military personnel vaccinated with either MenACYWD or meningococcal polysaccharide vaccine (MPSV4). Twelve hundred subjects vaccinated with MenACYW(D) from 2006 to 2008 or MPSV4 from 2002 to 2004 were randomly selected from the Defense Medical Surveillance System. Baseline serologic responses to MenC were assessed in all subjects; 100 subjects per vaccine group were tested during one of the following six post-vaccination time-points: 5-7, 11-13, 17-19, 23-25, 29-31, or 35-37 months. Anti-MenC geometric mean titers (GMT) were measured by rabbit complement serum bactericidal assay (rSBA) and geometric mean concentrations (GMC) by enzyme-linked immunosorbent assay (ELISA). Continuous variables were compared using the Wilcoxon rank sum test and the proportion of subjects with an rSBA titer >= 8 by chi-square. Pre-vaccination rSBA GMT was <8 for the MenACWY(D) group. rSBA GMT increased to 703 at 5-7 months post-vaccination and decreased by 94% to 43 at 3 years post-vaccination. GMT was significantly lower in the MenACWY(D) group at 5-7 months post-vaccination compared to the MPSV4 group. The percentage of MenACWY(D) recipients achieving an rSBA titer of >= 8 decreased from 87% at 5-7 months to 54% at 3 years. There were no significant differences between vaccine groups in the proportion of subjects with a titer of >= 8 at any time-point. GMC for the MenACWYD group was 0.14 mu g/mL at baseline, 1.07 mu g/mL at 5-7 months, and 0.66 mu g/mL at 3 years, and significantly lower than the MPSV4 group at all time-points. Anti-MenC responses wane following vaccination with MenACYW(D); a booster dose is needed to maintain protective levels of circulating antibody. Published by Elsevier Ltd.

TI High-Yield Synthesis of Mesoscopic Conductive and Dispersible Carbon Nanostructures via Ultrasonication of Commercial Precursors SO INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH LA English DT Article ID LIQUID-PHASE EXFOLIATION; REDUCED GRAPHENE OXIDE; ORGANIC-SOLVENTS; GRAPHITE OXIDE; RAMAN-SPECTROSCOPY; AQUEOUS-SOLUTION; THIN-FILMS; REDUCTION; NANOSCROLLS; SOLUBILITY AB The need to produce large quantities of graphenic materials displaying excellent conductivity, thermal resistance, and tunable properties for industrial applications has spurred interest in new techniques for exfoliating graphite. In this paper, sonication-assisted exfoliation of graphitic precursors in the presence of chloroform is shown to produce chemically and structurally unique exfoliated graphitic materials in high yields. These exfoliated graphites, referred to as mesographite and mesographene, respectively, exhibit unique properties which depend on the number of layers and exfoliation conditions. Structural characterization of mesographene reveals the presence of nanoscale two-dimensional graphene layers, and three-dimensional carbon nanostructures sandwiched between layers, similar to those found in ball-milled and intercalated graphites. The conductivities of mesographite and mesographene are 2700 and 2000 S/m, respectively, indicating high conductivity despite flake damage. Optical absorption measurements of mesographite sonicated in various solvents showed significant changes in dispersion characteristics, and also indicated significant changes to mesoscopic colloidal behavior. A mechanism for functionalization and formation of capped carbon nanostructures is proposed by integrating the chemical and structural characterization in relation to the various carbon structures observed by electron microscopy. Composites based on common polymers were prepared by solution processing, and changes in thermal properties indicate improved dispersion of mesographite in polar polymers.

In addition to the model development, a rigorous validation methodology was developed to quantify model performance. Experimental data for the geometry and dynamic properties of the ALL and PLL were used to create probabilistic FE models capable of predicting not only the mean dynamic relaxation response but also the observed experimental variation of that response. The probabilistic FE model uses a quasilinear viscoelastic material constitutive model to capture the time-dependent behaviour of the ligaments. The probabilistic analysis approach yields a statistical distribution for the model-predicted response at each time point rather than a single deterministic quantity (e.g. ligament force) and that response can be statistically compared to experimental data for validation. A quantitative metric that compares the cumulative distribution functions of the experimental data and model response is computed for both the ALL and PLL throughout the time histories and is used to quantify model performance.

Even though the rudder jam angle of five degrees was small and occurred during a planned movement of the rudder to affect a heading change, the jam was detected 97 seconds after it happened. The AIS design allowed the fault to be identified according to whether the fault affected the ship's vertical plane motion, horizontal plane motion, or transverse plane motion. The fault detection and identification was accomplished without any direct knowledge of the rudder motion or rudder angle. C1 Naval Surface Warfare Ctr, Carderock Div, West Bethesda, MD 20817 USA.

The nanosheets exhibited 2.7 times faster growth rate and much greater specific capacitance for a given growth time than CH4 synthesized films. Raman spectra showed that the intensity ratio of the D band to G band versus temperature initially decreased to a minimum value of 0.45 at a growth temperature of 750 degrees C, but increased rapidly with further temperature increase (1.15 at 850 degrees C). The AC specific capacitance at 120 Hz of these EDLC devices increased in a linear fashion with growth temperature, up to 265 mu F/cm(2) (2 mu m high film, 850 degrees C with 10 min growth). These devices exhibited ultrafast frequency response: the frequency response at -45 degrees phase angle reached over 20 kHz. Consistent with the increase in D band to G band ratio, the morphology of the films became less vertical, less crystalline, and disordered at substrate temperatures of 800 degrees C and above. This deterioration in morphology resulted in an increase in graphene surface area and defect density, which, in turn, contributed to the increased capacitance, as well as a slight decrease in frequency response. The low equivalent series resistance varied from 0.07 to 0.08 Omega and was attributed to the significant carbon incorporation into the Ni substrate.

TI Posttraumatic Stress Disorder After Combat Zone Deployment Among Navy and Marine Corps Men and Women SO JOURNAL OF WOMENS HEALTH LA English DT Article ID GENDER-DIFFERENCES; OEF/OIF VETERANS; HEALTH; IRAQ; AFGHANISTAN; SYMPTOMS; DEPRESSION; EXPOSURE; FEMALE; CARE AB Background: As more women are deployed into combat environments, preliminary findings have been inconsistent regarding gender differences in symptoms of posttraumatic stress disorder (PTSD) following deployment. Very little is known about the experiences of Navy and Marine Corps personnel deployed to combat zones. Methods: The study population consisted of Navy and Marine Corps personnel who completed a Post-Deployment Health Assessment upon return from deployment to Iraq, Afghanistan, or Kuwait during 2008 and 2009 and a Post-Deployment Health Reassessment approximately 6 months later. These instruments included screening questions for PTSD. Results: The final sample of 31,534 service members included 29,640 men and 1,894 women. Within occupation categories, women were overrepresented relative to men in the roles of functional support/administration and healthcare specialists, whereas men were overrepresented in the role of combat specialist. Screening rates were similar by gender, with a slightly higher percentage of women compared with men screening positive for PTSD (6.6% vs. 5.3%). These symptoms of PTSD among men and women in this sample could not be attributed to combat exposure or other deployment-related characteristics. Conclusions: Relative to men, women in this sample had a similar probability of screening positive for PTSD following deployment.

Prototype ship motions and environmental data were obtained in May 1999 in the deep-draft entrance channel at Barbers Point, HI. These field measurements were reproduced in controlled laboratory studies in 2000 and 2002 with a model of the World Utility (WU) bulk carrier. These measurements constitute some of the data being used to validate the Corps's Channel Analysis and Design Evaluation Tool (CADET), a suite of programs to determine the optimum dredge depth for entrance channels. In general, the CADET predictions matched the field and laboratory measurements within cm-accuracy for wave heights that ranged from 45 cm to 75 cm.

The objective of this study was to identify predictors of recovery among U.S. Marines who had musculoskeletal injuries of the back, knee, or shoulder. Methods A sample of 134 participants was assessed at baseline and followed for 1 year to determine outcome information. Results The strongest predictor of injury recovery at the 1-year follow-up was recovery expectations. In a multivariate logistic model with key demographic and psychosocial factors controlled, individuals who had high recovery expectations at baseline were over five times as likely to be recovered at follow-up as individuals who had low expectations (OR = 5.18, p < .01). Conclusions This finding is consistent with a large body of research that has linked recovery expectations with better recovery outcomes in patients with musculoskeletal injuries as well as with research linking recovery expectations with better outcomes across a wide range of medical conditions. Applied to military populations, interventions designed to modify recovery expectations may have the potential to improve rates of return to duty and to reduce rates of disability discharge.

In order to test the portability of a previously developed Della Torre-Oti-Kadar (DOK) stress-dependent Preisach model for high strength steels, a numerical model was implemented to replicate data taken on a non-trivial geometry made of the same material. The data used for comparison were measured previously by the National Institute of Standards and Technology on a toroidal-like sample which allowed for the simultaneous application of longitudinal stresses and transverse magnetic fields. The geometry was modeled in a finite element modeling package and coupled with a DOK model via material parameters. A coupling framework was developed and B-H loops were modeled and compared to the NIST data available with some agreement. In the future, this modeling approach will be extended to incorporate more complex field and stress interactions and applied to additional data sets as available. (C) 2014 AIP Publishing LLC.

The study investigates the effect of a constant transverse magnetic field and a cycling longitudinal magnetic field, applied sequentially, on the major hysteresis loop of solid cylinders of high strength steel. A coupled-hysteron vector Preisach model is extended to model the longitudinal magnetization of the samples under the effect of an applied transverse field. Insights about the microstructure of the rods and the contribution of different domains and magnetization mechanisms to the magnetic response are drawn. (C) 2014 AIP Publishing LLC.

TI Impact of Combat Deployment and Posttraumatic Stress Disorder on Newly Reported Coronary Heart Disease Among US Active Duty and Reserve Forces SO CIRCULATION LA English DT Article DE coronary disease; epidemiology; etiology; heart diseases; stress ID MILLENNIUM COHORT; MYOCARDIAL-INFARCTION; SELF-REPORT; MENTAL-DISORDERS; MILITARY SERVICE; PTSD CHECKLIST; PRIMARY-CARE; HEALTH; PREVALENCE; SYMPTOMS AB Background The recent conflicts in Iraq and Afghanistan have exposed thousands of service members to intense stress, and as a result, many have developed posttraumatic stress disorder (PTSD). The role of military deployment experiences and PTSD in coronary heart disease (CHD) is not well defined, especially in young US service members with recent combat exposure. Methods and Results We conducted a prospective cohort study to investigate the relationships between wartime experiences, PTSD, and CHD. Current and former US military personnel from all service branches participating in the Millennium Cohort Study during 2001 to 2008 (n=60 025) were evaluated for newly self-reported CHD. Electronic medical record review for International Classification of Diseases, Ninth Revision, Clinical Modification codes for CHD was conducted among a subpopulation of active duty members (n=23 794). Logistic regression models examined the associations between combat experiences and PTSD with CHD with adjustment for established CHD risk factors. A total of 627 participants (1.0%) newly reported CHD over an average of 5.6 years of follow-up. Deployers with combat experiences had an increased odds of newly reporting CHD (odds ratio, 1.63; 95% confidence interval, 1.11-2.40) and having a diagnosis code for new-onset CHD (odds ratio, 1.93; 95% confidence interval, 1.31-2.84) compared with noncombat deployers. Screening positive for PTSD symptoms was associated with self-reported CHD before but not after adjustment for depression and anxiety and was not associated with a new diagnosis code for CHD. Conclusions Combat deployments are associated with new-onset CHD among young US service members and veterans. Experiences of intense stress may increase the risk for CHD over a relatively short period among young adults.

Backscattered photons reduce image contrast as weak target returns compete against a large background of backscattered light. Forward scattering broadens the interrogating laser beam, thereby reducing the spatial resolution of the target. Prior research has shown that intensity modulation (<100 MHz) can be used to "wash-out" the backscatter, resulting in better discrimination of the target and higher contrast. We show that the higher modulation frequencies (>100 MHz) can be also used to suppress forward scattered light, thereby increasing spatial resolution.

TI Syndrome of Acute Anxiety Among Marines After Recent Arrival at High Altitude SO MILITARY MEDICINE LA English DT Article ID MENTAL-HEALTH PROBLEMS; PANIC DISORDER; AFGHANISTAN; IRAQ AB Management of mental health is critical for maintenance of readiness in austere military environments. Emerging evidence implicates hypoxia as an environmental trigger of anxiety spectrum symptomatology. One thousand thirty-six unacclimatized infantry Marines ascended from sea level to the Marine Corps Mountain Warfare Training Center (2,061-3,383 m) for a 30-day exercise. Within the first 6 days of training, 7 servicemen presented with severe, acute anxiety/panic with typical accompanying signs of sympathetic activation and no classic symptoms of acute mountain sickness (including headache). Four had a history of well-controlled psychiatric diagnoses. Invariably, cardiopulmonary and neurological evaluations were unrevealing, and acute cardiopulmonary events were excluded within limits of expeditionary diagnostic capabilities. All patients responded clinically to oxygen, rest, and benzodiazepines, returning to baseline function the same day. The unexpected onset of 7 cases of acute anxiety symptomatology coincident with recent arrival at moderate-to-high altitudes represents a highly unusual incidence and temporal distribution, suggestive of hypobaric hypoxemia as the proximal cause. We propose acute hypoxic physiological anxiety (AHPA) as a unique member of the spectrum of altitude-associated neurological disorders. Recognition of AHPA is particularly relevant in a military population; warfighters with anxiety spectrum diagnoses may have a recognizable and possibly preventable vulnerability.

Thomas, Anne Njeuhmeli, Emmanuel TI Achieving the HIV Prevention Impact of Voluntary Medical Male Circumcision: Lessons and Challenges for Managing Programs SO PLOS MEDICINE LA English DT Review ID SUB-SAHARAN AFRICA; MEN; HIV/AIDS; KISUMU; TRIAL; KENYA; INDIA AB Voluntary medical male circumcision (VMMC) is capable of reducing the risk of sexual transmission of HIV from females to males by approximately 60%. In 2007, the WHO and the Joint United Nations Programme on HIV/AIDS (UNAIDS) recommended making VMMC part of a comprehensive HIV prevention package in countries with a generalized HIV epidemic and low rates of male circumcision. Modeling studies undertaken in 2009-2011 estimated that circumcising 80% of adult males in 14 priority countries in Eastern and Southern Africa within five years, and sustaining coverage levels thereafter, could avert 3.4 million HIV infections within 15 years and save US$16.5 billion in treatment costs. In response, WHO/UNAIDS launched the Joint Strategic Action Framework for accelerating the scale-up of VMMC for HIV prevention in Southern and Eastern Africa, calling for 80% coverage of adult male circumcision by 2016. While VMMC programs have grown dramatically since inception, they appear unlikely to reach this goal. This review provides an overview of findings from the PLOS Collection "Voluntary Medical Male Circumcision for HIV Prevention: Improving Quality, Efficiency, Cost Effectiveness, and Demand for Services during an Accelerated Scale-up.'' The use of devices for VMMC is also explored. We propose emphasizing management solutions to help VMMC programs in the priority countries achieve the desired impact of averting the greatest possible number of HIV infections. Our recommendations include advocating for prioritization and funding of VMMC, increasing strategic targeting to achieve the goal of reducing HIV incidence, focusing on programmatic efficiency, exploring the role of new technologies, rethinking demand creation, strengthening data use for decision-making, improving governments' program management capacity, strategizing for sustainability, and maintaining a flexible scale-up strategy informed by a strong monitoring, learning, and evaluation platform.

Scott, Nikki LaSala, Victor MacKiewicz, James TI Composite materials dynamic back face deflection characteristics during ballistic impact SO JOURNAL OF COMPOSITE MATERIALS LA English DT Article DE resin-fiber composites; Ballistic response; digital image correlation; back face signature AB The current rationale for development of composite combat helmets is to either maintain performance at reduced weight or maintain weight with a significantly higher level of ballistic performance. Typically, weight reduction with maintained performance is the design approach used. In order to reduce weight with the same materials requires a reduction of material thickness. Thinner structural materials then introduce the complicating and often limiting factor of greater back face deflection. To further understand the tradeoffs of ballistic performance and efficiency, weight and back face deflection, a research project was undertaken. In this research project, a set of 17 composite materials were investigated. The digital image correlation method was used to directly measure the characteristics of the dynamic back face deflection of targets engaged by a set of threats. The analysis of this data, which includes dynamic deflection time histories, back face velocity time histories, strain time histories and spatial distributions of these quantities, allowed for assessment of candidate material performance and characterization of back face deflection. The details of this experimental program and key data results are presented in this paper.

Thermal analysis techniques such as differential scanning calorimetry (DSC) and thermogravimetric analysis were used to characterize the materials and for further understanding of reaction kinetics of the pyrophoric iron mixtures. The experimental results demonstrated that iron micron particles react exothermically to the oxygen in atmosphere and produced iron oxide with ignition temperature of 427.87 A degrees C and heat generation of 4,844 J g(-1). However, in this study, the pyrophoric iron mixture acts as a heat source for the thermoelectric power generators, the final mixture composition is determined to compose of iron powder, activated carbon, and sodium chloride with the mass ratio of approximately 5/1/1. The mixture generated two exothermic peaks DSC curves that showed ignition temperature of 431.53 and 554.85 A degrees C and with a higher heat generation of 9,366 J g(-1) at higher temperature. The effects of test pan materials and heating rate on the ignition were also examined by DSC method. Kinetic data such as the activation energy (E (a)), the entropy of activation (Delta S (#) ), enthalpy of activation (Delta H (#) ), and Gibbs energy of activation (Delta G (#) ) on the ignition processes was also derived from the DSC analysis. From the ignition temperature, heat generation, and kinetics test data, the mass ratio of 5/1/1 proved to generate the most amount of heat with high temperatures for the standalone thermoelectric power generators.

Although many studies examine stress hormone secretion and receptor activity, exciting new developments signify a shift in focus to neuromodulatory systems influencing neuronal development, survival, and neuroplasticity. The purpose of this study was to characterize salivary nerve growth factor (sNGF) responses to intense stress exposure in healthy military members undergoing survival training. A second purpose was to explore effects of age, sex, education, and body mass index (BMI). One hundred sixteen military members (80% male) were studied before, during, and 24 h after a stressful mock-captivity exercise. sNGF was measured at all three time points. Reactivity, recovery, and residual elevation of sNGF were computed. General linear modeling with repeated measures evaluated effect of stress exposure, as well as the roles of age, sex, education, and BMI. sNGF increased 137% from baseline to intense stress. During recovery, sNGF remained elevated an average of 67% above baseline (i.e., residual elevation). Men showed greater sNGF reactivity than women quantified by larger absolute T1 - T2 Delta (+148.1 pg/mL vs. +64.9 pg/mL, p < 0.017). A noteworthy trend of higher sNGF concentrations in low BMI participants was observed (p = 0.058). No effects of age or education were shown.

TI Hybrid technique for enhanced optical ranging in turbid water environments SO OPTICAL ENGINEERING LA English DT Article DE Lidar; laser range finders; modulation; scattering; optical properties; water; absorption; sensors ID MODULATED LASER IMAGER; LIGHT-PROPAGATION; SCATTERING; SYSTEMS; CLOUDS AB A hybrid approach is described that enhances the performance of an underwater optical ranging system. This approach uses high-frequency modulation and a spatial delay line filter to suppress unwanted backscatter. A dual frequency approach is also implemented to reduce the effects of forward scatter and remove the ambiguity associated with using the phase of the single, high-frequency modulation envelope to measure range. Controlled laboratory experiments were conducted to evaluate the effectiveness of the hybrid technique to reject multiple scattered light and improve range precision. The experimental results were compared with data generated from a theoretical model developed to predict the performance of the technique as a function of system and environmental variables. Model and experimental results are shown that reveal the ability of the approach to provide accurate ranging to an underwater object in a variety of water environments. Model predictions also indicate that advancements in transmitter and receiver technology will extend the range and improve the accuracy of the technique beyond what has been achieved thus far.

Cochenour, Brandon TI Underwater modulated pulse laser imaging system SO OPTICAL ENGINEERING LA English DT Article DE underwater; laser; three-dimensional imaging; modulation; forward-scatter suppression ID IMAGER AB The detection and identification of underwater threats in coastal areas are of interest to the Navy. When identifying a potential target, both two-dimensional (amplitude versus position) and three-dimensional (amplitude and range versus position) information are important. Laser imaging in turbid coastal waters makes this task challenging due to absorption and scattering in both the forward and backward directions. Conventional imaging approaches to suppress scatter rely on a pulsed laser and a range-gated receiver or an intensity-modulated continuous wave laser and a coherent RF receiver. The modulated pulsed laser imaging system is a hybrid of these two approaches and uses RF intensity modulation on a short optical pulse. The result is an imaging system capable of simultaneously acquiring high-contrast images along with high-precision unambiguous ranges. A working modulated pulsed laser line scanner was constructed and tested with a custom-built transmitter, a large-bandwidth optical receiver, and a high-speed digitizing oscilloscope. The effectiveness of the modulation to suppress both backscatter and forward scatter, as applied to both magnitude and range images, is discussed.

TI Dwell Time and Psychological Screening Outcomes Among Military Service Members With Multiple Combat Deployments SO MILITARY MEDICINE LA English DT Article ID MENTAL-HEALTH PROBLEMS; US MILITARY; GULF-WAR; ALCOHOL-USE; STRESS; VETERANS; IRAQ; AFGHANISTAN; DEPRESSION; PERSONNEL AB Recent studies have found that longer dwell times, or the period of time between deployments, may be protective against combat-related psychological outcomes. The purpose of this study was to examine the association between dwell time and psychological morbidity, while accounting for combat exposure. U.S. Marines with two combat deployments between 2005 and 2008 were identified from electronic deployment records. Those who screened positive for post-traumatic stress disorder and depression, and who were referred for mental health services were identified from the Post-Deployment Health Assessment. For the final study sample of 3,512 Marines, dwell time was calculated as time between deployments, and was analyzed as a ratio over length of first deployment. After adjustment for all covariates, there was an interaction (p = 0.01) between dwell time and combat exposure on mental health referral outcome. For personnel with maximum reported combat exposure, longer dwell times were associated with a 49% to 92% reduced odds of mental health referral. Longer dwell times may be protective against combat-related psychological outcomes. Because multiple deployments are likely to be the norm in future military operations, regulating dwell time, particularly for those with greater risk of combat exposure, should continue to be explored.

TI Changes in healthcare use across the transition from civilian to military life SO INTERNATIONAL JOURNAL OF HEALTH PLANNING AND MANAGEMENT LA English DT Article DE healthcare use; military; young adulthood; longitudinal; disparities ID UNITED-STATES; YOUNG-ADULTS; DISPARITIES; SERVICES; ACCESS AB Patterns of healthcare use in a sample of young adults entering the US Navy (N=1137) were examined in a longitudinal survey study. Baseline data provided information about healthcare use as a civilian, whereas follow-up data were used to examine changes in patterns of use over time following entry into the Military Health System (MHS). Entrance into the MHS was marked by increased use of preventive care. Although few systematic differences were noted with respect to socioeconomic status or race/ethnicity, women consistently used more healthcare than did men, and women's use increased more over time; however, this increase was largely driven by pregnancy during military service. Findings suggest that individuals with access to universal healthcare are likely to increase their overall use of services. However, these effects were quite small in absolute terms, and they were strongest for preventive care rather than more intensive and expensive services. Published 2013.

J increased with , BP, and CSC. BP and CSC provided the most benefit at lower . Incorporating BP and CSC improved the inner area J. A volumetric flow rate analysis conveyed the importance of disc diameterthe outer membrane area produced the majority of the total flow. Collectively, the results indicate that BP and CSC enhanced the standard HSR-MS flux performance at low by replacing the loss of or augmenting the rotationally induced shear. This conclusion supports HSR-MS operation at lower , which allows the use of larger disc diameters, providing an increase in performance per disc and a reduction in the number of membrane discs required.

Properties in the longitudinal direction are compared to transverse measurements made at the same locations. Compared to the BM the longitudinal direction shows strength and ductility increases throughout the weld. The outer SZ showed mechanical properties in the longitudinal direction to be similar to the SZ properties in the transverse direction. These observations and measured properties serve to link the local material properties to the complex flow, heat, and deformation imparted to the material during the FSW process.

Constant extension rate and rising step load testing on armor steel were conducted to evaluate the effect of the Zn-rich coating on environmentally assisted crack (EAC) initiation and propagation in a marine environment. It was found that the presence of the Zn-rich coating did moderately degrade the resistance to crack initiation compared to uncoated steel during immersion in artificial seawater. It was also found that the presence of the Zn-rich coating approximately doubled the crack propagation rates compared to uncoated steel in seawater immersion. Adding a chemical agent resistant coating (CARC) topcoat to the Zn-rich coating improved the resistance to crack initiation in the constant extension rate tests, but had no effect on the crack propagation rates. Intergranular and quasi-cleavage fracture modes were noted for the environment-affected test specimens. Seawater exposures followed by a drying time had no residual effect on crack initiation behavior in air as evaluated by the constant extension rate test. In the presence of a precrack, seawater exposure can serve to initiate cracking, and subsequent arrest during the drying period will depend on the mechanical driving force (i.e., applied stress intensity). The subcritical crack growth rates for Zn-coated material during the drying period is slower than under full immersion conditions, and is similar to, or less than, values obtained for the uncoated condition.

TI Mechanical Response of Silicon MEMS Diaphragms to Applied Pressure SO JOURNAL OF MICROELECTROMECHANICAL SYSTEMS LA English DT Article DE Microelectromechanical devices; silicon; pressure measurement ID SINGLE-CRYSTAL SILICON; INDENTATION; DEFORMATION; BEHAVIOR; SENSORS; FRACTURE; SYSTEMS AB The response of silicon-based MEMS diaphragms to applied pressure was studied to determine their ability to effectively measure the extent of blast overpressure. Different pressures (0-100 psi) were applied to silicon diaphragms of different diameters (1200, 1500, and 2200 mu m) to study their mechanical response under both static and dynamic conditions using experimental and finite element analysis. A laser triangulation sensor was used to determine the diaphragm displacement as a function of blast pressure. High speed camera images were obtained to understand the response of the diaphragm at an applied blast pressure. Results show consistent behavior for deflections (10, 14, and 26 mu m, respectively, at 40 psi) under dynamic conditions. Finite element analysis indicates that the dynamic deflection is larger than the corresponding static deflection for the same applied pressures. Burst strengths were not consistent, although the diaphragms fractured at their circumferential edges and showed a small degree of plastic deformation. It also appears that the diaphragm manifests a hemispherical as well as a conical deflection depending on applied blast pressures.

TI Child Maltreatment Before and After Combat-Related Deployment Among Active-Duty United States Air Force Maltreating Parents SO PSYCHOLOGY OF VIOLENCE LA English DT Article DE deployment; child maltreatment; Air Force; Operation Iraqi Freedom; Operation Enduring Freedom ID MENTAL-HEALTH PROBLEMS; POSTTRAUMATIC GROWTH; DIAGNOSTIC-CRITERIA; MILITARY; STRESS; IRAQ; AFGHANISTAN; SOLDIERS; ABUSE; ADVERSITY AB Objective: To conduct the first population-based study comparing the frequency of child maltreatment among active-duty United States Air Force (USAF) maltreating parents before and after combat-related deployment. Method: By combining archival databases, we identified 2,287 children with a total of 2,563 substantiated maltreatment incidents perpetrated by USAF parents who deployed during an 85-month study period during Operation Iraqi Freedom/Operation Enduring Freedom. Results: Contrary to expectations, overall the frequency of child maltreatment was significantly lower after than before deployment, and this pattern did not vary as a function of the number of combat-related deployments. Further, the frequency of child maltreatment was lower postdeployment relative to predeployment for emotional abuse, mild neglect, and maltreatment not involving alcohol, but the frequency was higher postdeployment for child sexual abuse and severe child neglect, particularly when severe child neglect involved alcohol. Conclusions: In general, among children who experienced parental maltreatment by a deploying USAF parent, milder forms of child maltreatment were less common postdeployment, whereas severe types of child maltreatment were more common. Possible explanations implicate predeployment differences in resources and functioning or postdeployment differences in posttraumatic growth and maturation between parental perpetrators of mild versus more severe maltreatment. Postdeployment child maltreatment surveillance efforts should be vigilant for signs of severe forms of child maltreatment, which appear to be most likely to increase.

We hypothesized that an extended period of impaired consciousness or early treatment with morphine could prevent consolidation of traumatic memory and the development of PTSD. To examine this hypothesis, we retrospectively reviewed 258 combat casualty records from the Iraq or Afghanistan conflicts from 2001-2008 in the Expeditionary Medical Encounter Database, including medications and Glasgow Coma Scale (GCS) scores recorded at in-theater facilities within hours of the index injury. All patients sustained amputations from injuries. Psychological diagnoses were extracted from medical records for 24 months postinjury. None of 20 patients (0%) with GCS scores of 12 or lower had PTSD compared to 20% of patients with GCS scores of 12 or greater who did have PTSD. For patients with traumatic brain injury, those treated with intravenous morphine within hours of injury had a significantly lower prevalence of PTSD (6.3%) and mood disorders (15.6%) compared to patients treated with fentanyl only (prevalence of PTSD = 41.2%, prevalence of mood disorder = 47.1%). GCS scores and morphine and fentanyl treatments were not significantly associated with adjustment, anxiety, or substance abuse disorders.

TI Deployment Experiences and Motor Vehicle Crashes Among US Service Members SO AMERICAN JOURNAL OF PREVENTIVE MEDICINE LA English DT Article ID WAR-ERA VETERANS; MILLENNIUM COHORT; VIETNAM VETERANS; GULF-WAR; MILITARY PERSONNEL; MENTAL-DISORDERS; PRIMARY-CARE; PRIME-MD; HEALTH; MORTALITY AB Background: Motor vehicle crashes (MVCs) continue to account for a third of service member fatalities each year. Sociodemographic factors associated with MVCs among service members have been evaluated, but whether deployment-specific experiences during the recent operations are associated with a higher risk of MVCs is unclear. Purpose: Evaluate if military members with specific deployment experiences are at an increased risk of MVCs, while taking into account several potential confounders. Methods: Millennium Cohort Study participants who enrolled during 2001-2006 and were on active-duty service were evaluated. The Military Health System Data Repository (MDR) was used to investigate MVC-related injuries occurring 6 months postdeployment in relation to service-related factors, while adjusting for demographic, behavioral, and mental and physical health factors. Analysis conducted in 2012 used Cox proportional hazards modeling. Results: There were 13,620 deployed personnel included in this study. After adjusting for covariates, deployers with combat experiences (hazard ratio [HR]=1.86, 95% CI=1.33, 2.62) and those with more than one deployment (two deployments, HR=1.93, 95% CI=1.32, 2.83; three or more deployments, HR=2.83, 95% CI=1.71, 4.67) had an increased risk for an MVC within 6 months postdeployment. Enlisted rank and non-Hispanic black race/ethnicity were also associated with increased risk for MVCs. Conclusion: Experiencing combat during deployment and multiple deployments are both strong predictors for MVCs within 6 months of returning home among U. S. military members. These data provide critical information for targeting prevention strategies to decrease MVCs among personnel postdeployment.

Evidence suggests that anti-M2 antibody responses following influenza A virus infection are weak and/or transient. We show that the seroprevalence of anti-M2 antibodies increased with age in 317 serum samples from healthy individuals in the United States in 2007-2008. Infection with 2009 pandemic H1N1 influenza A virus (A[H1N1]pdm09) elicited a recall serum antibody response to M2 protein of A(H1N1)pdm09 in 47% of the affected 118 individuals tested. Anti-M2 antibody responses were more robust among individuals with preexisting antibodies to M2 protein. Moreover, the antibodies induced as a result of infection with A(H1N1)pdm09 were cross-reactive with M2 protein of seasonal influenza A viruses. These results emphasize the need to further investigate the possible roles of anti-M2 antibodies in human influenza A virus infection.

Initial beta formation occurs more readily at low-angle grain boundaries than at high-angle boundaries; however, larger precipitates are found at high-angle boundaries. We propose a mechanism for beta formation based on boundary energy and grain boundary free volume. These results advance the understanding of beta phase formation, aiding future corrosion prevention.

Methods: The study population included active duty military personnel and the general population aged 18 to 56 years. Data were obtained from the U.S. Department of Defense medical data systems and from the Surveillance Epidemiology and End Results program. Melanoma risk was estimated by incidence rate ratios (IRRs). Results: Melanoma risk was higher among active duty personnel than the general population (IRR = 1.62, 95% confidence interval = 1.40-1.86). Incidence rates were higher for white military personnel than for white rates in general population (36.89 and 23.05 per 100,000 person-years, respectively). Rates were also increased for military men and women compared with SEER (men, 25.32 and 16.53 per 100,000; women, 30.00 and 17.55 per 100,000). Air Force service personnel had the highest rates and Army had the lowest. Conclusion: Melanoma rates were marginally higher among active duty military personnel than the general population between 2000 and 2007. C1 [Lea, C.

We describe the study design and methods of the Wounded Warrior Recovery Project, a study supported by the Department of Defense that will track close to 10,000 military personnel wounded in Operations Enduring Freedom and Iraqi Freedom. The overall objective of the 6-year longitudinal study is to track changes in QOL and describe variations in those changes as they relate to sociodemographic factors, injury characteristics, service-related factors, clinical/diagnostic measures including traumatic brain injury and posttraumatic stress disorder, and medical procedures and services. The Wounded Warrior Recovery Project study will be among the first longitudinal population-based investigations of QOL outcomes after combat injury and will provide a basis upon which large-scale epidemiological studies can be conducted.

TI Paradoxical Reduction in HDL-C With Fenofibrate and Thiazolidinedione Therapy in Type 2 Diabetes: The ACCORD Lipid Trial SO DIABETES CARE LA English DT Article ID HIGH-DENSITY-LIPOPROTEIN; PROLIFERATOR-ACTIVATED RECEPTOR; ROSIGLITAZONE; CHOLESTEROL; ALPHA; METABOLISM; EXPRESSION; MELLITUS; DISEASE; FIBRATE AB OBJECTIVETo determine the occurrence of extremely low HDL cholesterol (HDL-C) among participants in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) Lipid Trial and to examine the relationship of this finding with treatment with fenofibrate and thiazolidinedione (TZD).RESEARCH DESIGN AND METHODSThe ACCORD Lipid Trial was a randomized, double-blind, placebo-controlled study conducted in patients with type 2 diabetes at 77 clinical centers across the U.S. and Canada in a 5,518-patient subset of the larger 10,251 ACCORD Glycemia Trial. Patients were enrolled from 11 January 2001 to 29 October 2005 and followed until the end of study visits between 1 March and 30 June 2009. Follow-up in the ACCORD Lipid Trial was 4-8 years (mean 4.7 years). Patients were treated with blinded fenofibrate or placebo on a background of simvastatin therapy. The main outcome measures for these descriptive, post hoc analyses was the occurrence of extremely low HDL-C (defined as <25 mg/dL [0.647 mmol/L]) during the trial.RESULTSAmong ACCORD Lipid Trial participants, the occurrence of extremely low HDL-C ever during study follow-up was 106% higher among those randomized to fenofibrate (10.1% fenofibrate vs. 4.9% placebo, P < 0.001). The occurrence of low HDL-C was associated with concurrent treatment with fenofibrate and TZD (7.0% for both vs. 2.2% for neither at 48 months postrandomization).CONCLUSIONSIdiosyncratic and marked reduction in HDL-C can occur in some patients treated with both fenofibrate and TZD. Practitioners should recognize this important potential idiosyncratic reaction and take appropriate corrective action. C1 [Linz, Peter E.] US Naval Hosp, San Diego, CA 92134 USA.

TI A Method to Predict Rudder Stall Inception from Two-dimensional Airfoil Data SO JOURNAL OF SHIP RESEARCH LA English DT Article DE rudders; rudder stall; maneuvering; hydrofoil theory; airfoil stall ID DYNAMIC STALL AB The behavior of the force on a rudder changes significantly after the inception of stall, requiring different mathematical formulae to compute rudder forces prior- and poststall. Determining the inception angle at which stall occurs is important for predicting the rudder force on a maneuvering ship. A method to compute the inception angle of stall on a rudder is presented in this article. The theoretical formulation is based on a flow similarity approach, which relates three-dimensional rudder stall inception with two-dimensional airfoil data. Rudders are low-aspect ratio wings, and the three-dimensional lift is based on the low-aspect ratio wing theory. The two-dimensional airfoil stall data are obtained from National Advisory Committee for Aeronautics (NACA) reports. The derived theory is first validated with wind tunnel data from foils with a NACA 0015 profile of aspect ratios 1, 2, and 3. The theory is also validated with data from foils with a NAPA 0012 profile and an aspect ratio of 2, 3, and 6.

Materials and Methods: A meta-analysis was performed of five studies of the relationship between 25(OH)D and mortality from breast cancer. A pooled hazard ratio was calculated using a random-effects model. The Der Simonian-Laird test was used to assess homogeneity. Results: Higher serum concentrations of 25(OH)D were associated with lower case-fatality rates after diagnosis of breast cancer. Specifically, patients in the highest quintile of 25(OH)D had approximately half the death rate from breast cancer as those in the lowest. Conclusion: High serum 25(OH)D was associated with lower mortality from breast cancer. Serum 25(OH)D in all patients with breast cancer should be restored to the normal range (30-80 ng/ml), with appropriate monitoring. Clinical or field studies should be initiated to confirm that this association was not due to reverse causation.

Although PTSD comorbidity has been associated with more severe and chronic symptomology, relationships among commonly co-occurring disorders are not well understood. The purpose of this study was to review the literature regarding the development of depression comorbid with combat-related PTSD among military personnel. We summarize results of commonly tested hypotheses about the etiology of PTSD and depression comorbidity, including (1) causal hypotheses, (2) common factor hypotheses, and (3) potential confounds. Evidence suggests that PTSD may be a causal risk factor for subsequent depression; however, associations are likely complex, involving bidirectional causality, common risk factors, and common vulnerabilities. The unique nature of PTSD-depression comorbidity in the context of military deployment and combat exposure is emphasized. Implications of our results for clinical practice and future research are discussed. Published by Elsevier Ltd.

TI Prediction of the Sandia Fracture Challenge using a shear modified porous plasticity model SO INTERNATIONAL JOURNAL OF FRACTURE LA English DT Article DE Plasticity; Ductile fracture; Gurson model; Sandia Fracture Challenge ID DUCTILE CRACK-GROWTH; STRAIN; VOIDS AB Blind analyses of the localization and ductile fracture behavior of an arbitrarily shaped coupon, performed for the Sandia Fracture Challenge, are presented. These analyses were performed using a shear-modified Gurson porous plasticity model that was calibrated using standard mechanical test data. The blind predictions were found to be in good agreement with experimental data, thus increasing confidence in the calibration methodology where test data is not available. In addition to the analyses submitted to the Challenge, additional non-blind analyses examining the role of both as-machined versus nominal coupon geometry and the selected value of initial porosity were conducted. It was found that by capturing the as-machined, out of tolerance, geometry in numerical calculations the fracture mode was altered from tension to shear. This agrees well with the experimental observation that all in-tolerance coupons failed in a tensile mode while all out-of-tolerance coupons failed in a shear mode. Additionally, it was found that by modifying the initial void volume fraction to a lower value still within the range that the calibration methodology provided, calculations capturing this as-machined geometry were able to closely match experimental results.

The results typically show multiple patterns which vary depending On the specimen under study and the mechanism by which the stress is applied. The measurements presented in the literature for iron, nickel, and steels show two unique magnetic features; the stress crossover and the bulging of the magnetization loop. The existence of these features in the magnetization measurements of different sets of high strength steel is studied. A statistical interpretation of the Preisach diagram is utilized to explain and model their existence. The modified DOK Preisach model effectively simulated the two features. (c) 2013 Elsevier B.V.

Previous studies on the magnetostriction in high strength steels have ignored the internal anisotropies due to prior material handling. To this end, a measurement utilizing two perpendicular fields was designed to interrogate the magnetic texture and microstructure of high-strength steel rods. These magnetization and magnetostriction measurements were then fitted to an energy-based domain rotation model which had been altered to address vector fields and uniaxial anisotropies. Given the simplicity of the model it is surprising to see that it captures a number of the general trends in the Data, however the fit is generally poor. Improving upon this data set will allow us to determine general magnetic characteristics of microstructure in the steels. These measurements will be incorporated into a future Vector Preisach model allowing detailed predictions of the magnetic state after stress and field changes in multiple directions.

TI Geometric Effects on Stress Wave Propagation SO JOURNAL OF BIOMECHANICAL ENGINEERING-TRANSACTIONS OF THE ASME LA English DT Article DE guided wave propagation; elastic wave interaction and reflection; finite element analysis; dispersion in waveguides; stress wave mitigation; bioinspired design; geometric effects ID BIGHORN SHEEP; SHOCK; WOODPECKER; DESIGN; GUIDES AB The present study, through finite element simulations, shows the geometric effects of a bioinspired solid on pressure and impulse mitigation for an elastic, plastic, and viscoelastic material. Because of the bioinspired geometries, stress wave mitigation became apparent in a nonintuitive manner such that potential real-world applications in human protective gear designs are realizable. In nature, there are several toroidal designs that are employed for mitigating stress waves; examples include the hyoid bone on the back of a woodpecker's jaw that extends around the skull to its nose and a ram's horn. This study evaluates four different geometries with the same length and same initial cross-sectional diameter at the impact location in three-dimensional finite element analyses. The geometries in increasing complexity were the following: (1) a round cylinder, (2) a round cylinder that was tapered to a point, (3) a round cylinder that was spiraled in a two dimensional plane, and (4) a round cylinder that was tapered and spiraled in a two-dimensional plane. The results show that the tapered spiral geometry mitigated the greatest amount of pressure and impulse (approximately 98% mitigation) when compared to the cylinder regardless of material type (elastic, plastic, and viscoelastic) and regardless of input pressure signature. The specimen taper effectively mitigated the stress wave as a result of uniaxial deformational processes and an induced shear that arose from its geometry. Due to the decreasing cross-sectional area arising from the taper, the local uniaxial and shear stresses increased along the specimen length. The spiral induced even greater shear stresses that help mitigate the stress wave and also induced transverse displacements at the tip such that minimal wave reflections occurred. This phenomenon arose although only longitudinal waves were introduced as the initial boundary condition (BC). In nature, when shearing occurs within or between materials (friction), dissipation usually results helping the mitigation of the stress wave and is illustrated in this study with the taper and spiral geometries. The combined taper and spiral optimized stress wave mitigation in terms of the pressure and impulse; thus providing insight into the ram's horn design and woodpecker hyoid designs found in nature.

TI Traumatic Brain Injury and PTSD Screening Efforts Evaluated Using Latent Class Analysis SO REHABILITATION PSYCHOLOGY LA English DT Article DE traumatic brain injury; posttraumatic stress disorder; latent class analysis; postconcussive symptoms; postdeployment health assessment ID POSTTRAUMATIC-STRESS-DISORDER; CONFIRMATORY FACTOR-ANALYSIS; CONCUSSION SYMPTOMS QUESTIONNAIRE; MENTAL-HEALTH PROBLEMS; POSTCONCUSSIVE SYMPTOMS; MILITARY PERSONNEL; GULF-WAR; VETERANS; COMBAT; IRAQ AB Objective: To empirically identify latent classes of service members according to persistent postconcussive symptom patterns and to characterize the identified classes relative to other postdeployment variables including posttraumatic stress disorder (PTSD) and mild traumatic brain injury (TBI) screening results. Such comparisons may directly inform policy regarding these routine assessments and translate to improved treatment decisions. Method: Self-report data were obtained for 12,581 combat-exposed male U. S. Navy and Marine Corps personnel who returned from deployment in 2008-2009 and completed a Post-Deployment Health Assessment (PDHA) and an associated Post-Deployment Health Reassessment (PDHRA). Persistent postconcussive symptoms indicated on the PDHRA were used as manifest variables in a latent class analysis yielding 4 distinct classes: systemic, cognitive/behavioral, comorbid, and nonpresenting. Results: Although the nonpresenting class endorsed few or no postconcussive symptoms, the systemic and cognitive/behavioral classes displayed elevated likelihoods of neurological and mental health symptoms, respectively. Members of the comorbid class had an increased probability of reporting a wide range of symptoms across both domains. Characterization of identified classes suggested that class membership may indicate the presence or absence of persistent conditions resulting from head injury and/or mental health issues. Under this assumption, estimated class membership probabilities implied a rate of probable neurological injury among this sample to be 17.9%, whereas the standard assessments aimed at identifying repercussions of mild TBI reported a positive screening rate of only 13.1%. Conclusions: Findings suggest that the routinely administered PDHA and PDHRA appear to underestimate the true prevalence of service members experiencing postdeployment health problems. Supplemental items or an alternative screening algorithm incorporating persistent postconcussive symptoms may enable identification of additional cases requiring treatment following return from deployment.

CA Marine Resiliency Study Team TI Association Between Traumatic Brain Injury and Risk of Posttraumatic Stress Disorder in Active-Duty Marines SO JAMA PSYCHIATRY LA English DT Article ID ADMINISTERED PTSD SCALE; PERSISTENT POSTCONCUSSIVE SYMPTOMS; DEPLOYED MILITARY PERSONNEL; OPERATION IRAQI FREEDOM; MENTAL-HEALTH; PSYCHOLOGICAL SYMPTOMS; PSYCHIATRIC DIAGNOSES; ANXIETY DISORDERS; UNITED-STATES; SUICIDE RISK AB IMPORTANCE Whether traumatic brain injury (TBI) is a risk factor for posttraumatic stress disorder (PTSD) has been difficult to determine because of the prevalence of comorbid conditions, overlapping symptoms, and cross-sectional samples. OBJECTIVE To examine the extent to which self-reported predeployment and deployment-related TBI confers increased risk of PTSD when accounting for combat intensity and predeployment mental health symptoms. DESIGN, SETTING, AND PARTICIPANTS As part of the prospective, longitudinal Marine Resiliency Study (June 2008 to May 2012), structured clinical interviews and self-report assessments were administered approximately 1 month before a 7-month deployment to Iraq or Afghanistan and again 3 to 6 months after deployment. The study was conducted at training areas on a Marine Corps base in southern California or at Veterans Affairs San Diego Medical Center. Participants for the final analytic sample were 1648 active-duty Marine and Navy servicemen who completed predeployment and postdeployment assessments. Reasons for exclusions were nondeployment (n = 34), missing data (n = 181), and rank of noncommissioned and commissioned officers (n = 66). MAIN OUTCOMES AND MEASURES The primary outcome was the total score on the Clinician-Administered PTSD Scale (CAPS) 3 months after deployment. RESULTS At the predeployment assessment, 56.8% of the participants reported prior TBI; at postdeployment assessment, 19.8% reported sustaining TBI between predeployment and postdeployment assessments (ie, deployment-related TBI). Approximately 87.2% of deployment-related TBIs were mild; 250 of 287 participants (87.1%) who reported posttraumatic amnesia reported less than 24 hours of posttraumatic amnesia (37 reported >= 24 hours), and 111 of 117 of those who lost consciousness (94.9%) reported less than 30 minutes of unconsciousness. Predeployment CAPS score and combat intensity score raised predicted 3-month postdeployment CAPS scores by factors of 1.02 (P < .001; 95% CI, 1.02-1.02) and 1.02 (P < .001; 95% CI, 1.01-1.02) per unit increase, respectively. Deployment-related mild TBI raised predicted CAPS scores by a factor of 1.23 (P < .001; 95% CI, 1.11-1.36), and moderate/severe TBI raised predicted scores by a factor of 1.71 (P < .001; 95% CI, 1.37-2.12). Probability of PTSD was highest for participants with severe predeployment symptoms, high combat intensity, and deployment-related TBI. Traumatic brain injury doubled or nearly doubled the PTSD rates for participants with less severe predeployment PTSD symptoms. CONCLUSIONS AND RELEVANCE Even when accounting for predeployment symptoms, prior TBI, and combat intensity, TBI during the most recent deployment is the strongest predictor of postdeployment PTSD symptoms.

The co-occurrence of alcohol misuse and mental health disorders is termed dual disorder and has been associated with adverse outcomes. Methods: The study included 812 high-risk (i.e., endorsing combat exposure with documented combat injury) male U.S. veterans of Operation Iraqi Freedom, injured between October 2004 and November 2007, identified from the Expeditionary Medical Encounter Database. Results: PTSD and depression symptoms were significant correlates of alcohol misuse. Veterans with dual disorder symptoms reported a significantly higher mean number of health complaints on the Post-Deployment Health Reassessment compared with those endorsing only mental health symptoms. Conclusions: These results highlight how mental health disorders among injured service members increases the odds of problem drinking and those with dual disorder have elevated health complaints.

Combat personnel with histories of mTBI exhibit abnormal activation of distributed brain networks including emotion processing and default mode networks. How developing PTSD further affects these abnormalities has not been directly examined. We recorded electroencephalography in combat veterans with histories of mTBI, but without active PTSD (mTBI only, n=16) and combat veterans who developed PTSD after mTBI (mTBI + PTSD, n = 16) during the Reading the Mind in the Eyes Test (RMET), a validated test of empathy requiring emotional appraisal of facial features. Task-related event related potentials (ERPs) were identified, decomposed using independent component analysis (ICA) and localized anatomically using dipole modeling. We observed larger emotional face processing ERPs in veterans with mTBI + PTSD, including greater N300 negativity. Furthermore, greater N300 negativity correlated with greater PTSD severity, especially avoidance/numbing and hyperarousal symptom clusters. This correlation was dependent on contributions from the precuneus and posterior cingulate cortex (PCC). Our results support a model where, in combat veterans with histories of mTBI, larger ERPs from overactive posterior-medial cortical areas may be specific to PTSD, and is likely related to negative selfreferential activits.

The objective of this study was to investigate the effectiveness of an amorphous silica encapsulation (ASE) technology by evaluating its silica coating efficiency (SCE), particle morphology, and its impact on the weld's mechanical properties. Tetramethylsilane (TMS) added to the welding shielding gas decomposed at the high-temperature arc zone to enable the silica coating. Collected welding fume particles were digested by two acid mixtures with different degrees of silica solubility, and the measured mass differences in the digests were used to determine the SCE. The SCEs were around 48-64% at the low and medium primary shielding gas flow rates. The highest SCE of 76% occurred at the high shielding gas flow rate (30 Lpm) with a TMS carrier gas flow of 0.64 Lpm. Transmission electron microscopy (TEM) images confirmed the amorphous silica layer on the welding fume particles at most gas flow rates, as well as abundant stand-alone silica particles formed at the high gas flow rate. Metallography showed that welds from the baseline and from the ASE technology were similar except for a tiny crack found in one particular weld made with the ASE technology. Tensile tests showed no statistical difference between the baseline and the ASE welds. All the above test results confirm that welding equipment retrofitted with the ASE technology has the potential to effectively address the toxicity problem of welding fume particles without affecting the mechanical properties of the welds.

Commercially pure (CP) aluminum feedstock powder has been deposited on Al2024-T351 samples using a cold-spray coating technique known as high velocity particle consolidation. Substrate specimens were prepared by surface grit blasting or shot peening prior to coating. The fatigue behavior of both coated and uncoated specimens was then tested under rotating bend conditions at two stress levels, 180 MPa and 210 MPa. Scanning electron microscopy was used to analyze failure surfaces and identify failure mechanisms. The results indicate that the fatigue strength was significantly improved on average, up to 50% at 180 MPa and up to 38% at 210 MPa, by the deposition of the cold-sprayed CP-Al coatings. Coated specimens first prepared by glass bead grit blasting experienced the largest average increase in fatigue life over bare specimens. The results display a strong dependency of the fatigue strength on the surface preparation and cold spray parameters. (C) 2013 Elsevier Ltd. All rights reserved. C1 [Ziemian, C. W.; Sharma, M.

To address the CMAS attack some approaches have been advanced based upon sealing the TBC or altering the TBC composition. A new strategy is presented based upon the application of a MoSiB based coating applied by pack cementation. The interaction between the MoSiB-based coating on a Mo substrate and CMAS is evaluated on two types of natural CMAS sands and on a commonly studied synthetic CMAS. The MoSiB-based coating arrests CMAS melt penetration by an in-situ reaction that yields crystallization products that act to immobilize the CMAS. The coating design is demonstrated to be effective in preventing CMAS attack during isothermal exposure at temperatures up to at least 1500 degrees C and during thermal cycling.

Utilizing the U.S. military healthcare system, which minimizes confounding from healthcare access, we analyzed whether timing of HAART initiation and the appropriate initiation of primary prophylaxis among those at high risk for pneumocystis pneumonia (PCP) varies by race/ethnicity. Methods: Participants in the U. S. Military HIV Natural History Study from 1998-2009 who had not initiated HAART before 1998 and who, based on DHHS guidelines, had a definite indication for HAART (CD4 <200, AIDS event or severe symptoms; Group A), an indication to consider HAART (including CD4 <350; Group B) or electively started HAART (CD4 >350; Group C) were analyzed for factors associated with HAART initiation. In a secondary analysis, participants were also evaluated for factors associated with starting primary PCP prophylaxis within four months of a CD4 count <200 cells/mm(3). Multiple logistic regression was used to compare those who started vs. delayed therapy; comparisons were expressed as odds ratios (OR). Results: 1262 participants were evaluated in the analysis of HAART initiation (A = 208, B = 637, C = 479 [ 62 participants were evaluated in both Groups A and B]; 94% male, 46% African American, 40% Caucasian). Race/ethnicity was not associated with HAART initiation in Groups A or B. In Group C, African American race/ethnicity was associated with lower odds of initiating HAART (OR 0.49, p = 0.04). Race and ethnicity were also not associated with the initiation of primary PCP prophylaxis among the 408 participants who were at risk. Conclusions: No disparities in the initiation of HAART or primary PCP prophylaxis according to race/ethnicity were seen among those with an indication for therapy. Among those electively initiating HAART at the highest CD4 cell counts, African American race/ethnicity was associated with decreased odds of starting. This suggests that free healthcare can potentially overcome some of the observed disparities in HIV care, but that unmeasured factors may contribute to differences in elective care decisions.

This paper describes a treadmill-based method for delivering postural perturbations during locomotion to evoke a trip-like response and serve as a surrogate for an overground trip. Subjects walked at a normalized velocity in a Computer Assisted Rehabilitation Environment (CAREN). During single-limb stance, the treadmill belt speed was rapidly changed, thereby requiring the subject to perform a compensatory stepping response to avoid falling. Peak trunk flexion angle and peak trunk flexion velocity during the initial compensatory step following the perturbation were smaller for responses associated with recoveries compared to those associated with falls. These key fall prediction variables were consistent with the outcomes observed for laboratory-induced trips of older adults. This perturbation technique also demonstrated that this method of repeated but randomly delivered perturbations can evoke consistent, within-subject responses. (C) 2013 Elsevier Ltd.

We theoretically show that by adjusting the number of pulses and the -pulse timing, we can control the frequency selectivity of the interferometer to time varying and DC magnetic fields. We present experimental data demonstrating increased coherence time due to bandwidth filtering with the inclusion of a pulse between the initial and final pulses, which mitigates sensitivity to low frequency magnetic fields.

Hypoxia is a medical condition affecting portions of the body that are deprived of oxygen supply. Prolonged exposure to cerebral oxygen deficiency can lead to unconsciousness or even death. The onset of hypoxia in humans is of concern for those operating in high altitudes, and in military flights characterized by high-acceleration maneuvers. Using oximeters for measuring blood oxygen saturation levels is a common means to detect hypoxia in real time. Many types of oximeters can be used for this task but all are prone to complicated noise characteristics and bias inaccuracies. It may therefore be advisable to collect and combine data streams from multiple oximeters for more reliable Hypoxia/No Hypoxia decisions (compared to decisions made by a single oximeter). Here we develop statistical noise models for three popular types of oximeters (Respironics Novametrix 515B, Nonin forehead pulse oximeter 9847, and Masimo Rad-87). We also combine data streams from these oximeters using a Kalman filter. The result is a smooth and reliable estimate of blood oxygen saturation level which can be used to detect the onset of Hypoxia.

Some metrics focus on estimation accuracy by comparing estimated quantities to the truth. Other metrics assess the accuracy of the estimation uncertainty by determining the consistency of the estimation error covariance. In this paper we define two metrics that quantify the data association algorithm's performance (whether the data are measurements or tracks). We compare the metric to a few existing metrics that quantify the effects of data association and evaluate the new metrics both with some notional examples and with some simulated data run through a track-to-track (T2T) fusion algorithm. Finally, we discuss a direct analogy between the data association problem and the information retrieval problem and reference two metrics in the information retrieval domain that are equivalent to the two metrics proposed in this paper.

In this work, a high-fidelity, fluid-structure coupled computational approach is developed to simulate such an event. It allows quantitative prediction of the dynamics of acoustic and shock waves in water and the initiation and propagation of cracks in the structure. This computational approach features an extended finite element method ()OEM) for the highly-nonlinear structural dynamics characterized by large plastic deformation and fracture. It also features a finite volume method with exact two-phase Riemann solvers (FIVER) for the solution of the multi-material flow problem arising from the contact of gas and water after the structure fractures. The Eulerian computational fluid dynamics (CFD) solver and the Lagrangian computational structural dynamics (CSD) solver are coupled by means of an embedded boundary method of second-order accuracy in space. The capabilities and performance of this computational approach are explored and discussed in the full-scale simulations of a laboratory implosion experiment with hydrostatic loading and a three-dimensional manufactured implosion problem with explosion loading.

Experiments and nondestructive evaluation (NDE) have illustrated good correlations between impact energy and foreign object damage (POD) assessed using electrical resistivity (ER), acoustic emission (AE), and microscopy. In this paper, a progressive failure dynamic analysis (PFDA) method is explored in understanding and predicting the damage states, electrical resistivity, and residual strength after impact of CMCs. In general, CMCs are modeled using effective fiber, matrix, and interface constitutive behaviors, from which the lamina stiffness and strengths can be derived. Similarly, the electrical resistivity of a lamina is homogenized based on the percolation theory for inclusion/discontinuities dispersion in a matrix for voids and Si particles, as well as fibers, and damages after impact. To accurately correlate the damage state with ER, the PFA tool has been improved to incorporate the physical damage mechanisms in CMCs, which are matrix microcrack density due to both longitudinal and transverse tensile loads and the fiber breakage due to probabilistic fiber strength distribution. The predicted damage states and ER are correlated with the measurement of FOD and validated with tension after impact tests using high temperature ER. The PFDA tool has demonstrated a great potential for CMCs' POD and residual strength predictions. C1 [Abdi, Frank; Xue, Yibin] AlphaSTAR Corp, Long Beach, CA 90804 USA.

As the aerospace industry draws closer to implementing ceramic matrix composites (CMCs) in gas turbines, the corresponding behavior in these materials after such events needs to be understood. To address this requirement, several silicon infiltrated fiber reinforced SiC/SiC coupons were impacted with high speed projectiles with velocities up to 360 m/s with an impact rig built at the University of Akron and NAVAIR. The resulting damage states were assessed using several non-destructive evaluation (NDE) techniques and compared to actual damage condition observed through the sectioning of impacted coupons. Ultimately, the true consequence of the damage was revealed by measuring the post-impact, residual strengths via uniaxial tensile tests to failure at both room and elevated temperatures. Lastly, the NDE results revealed a complicated damage morphology consisting of in-and-out-of plane damage that significantly affected the retained mechanical properties.

This work was an extension and companion of the previous work conducted in dynamic fatigue. Four different applied stresses ranging from 120 to 170 MPa was incorporated with a total of 20-23 test specimens used at each of four applied stresses. The slow crack growth parameters n and D were found to be n=19 and D=45 with a coefficient of correlation of r(coef) = 0.9653. The Weibull modulus of time to failure was in a range of m(sf)=1.6 to 1.9 with an average of m(sf)=1.7 +/- 0.2. A life prediction using the previously-determined dynamic fatigue data was in excellent agreement with the static fatigue data. The life prediction approach was also applied to advanced monolithic ceramics and ceramic matrix composites based on their dynamic and static fatigue data determined at elevated temperatures. All of these results indicated that a SCG mechanism governed by a power-law crack-growth formulation was operative, a commonality of slow crack growth in these materials systems.

GP ASME TI Blast Overpressure Measured on a Bare vs. Helmeted Rigid Headform SO PROCEEDINGS OF THE ASME INTERNATIONAL MECHANICAL ENGINEERING CONGRESS AND EXPOSITION, 2013, VOL 3A LA English DT Proceedings Paper CT ASME International Mechanical Engineering Congress and Exposition (IMECE2013) CY NOV 15-21, 2013 CL San Diego, CA SP ASME ID INJURY AB There is significant concern that blast overpressure can cause mild traumatic brain injury (mTBI). An accurate understanding of the blast flow and overpressure event as well as it's interaction with the head and helmet system is a necessary first step in establishing loading conditions to the head. It also provides a means for model validation and other predictive capabilities. A custom-designed Blast Overpressure Bust (BOB) containing 22 surface pressure sensors was rigidly mounted in a live-fire blast event. The blast field tests were conducted in an open field using 4 lbs. of cylindrical C4 charges suspended 48 '' above the pad. The BOB was mounted to a torso surrogate and positioned 92 '' from the hanging charge. The BOB was oriented at blast impact angles of 0 (front-facing), 45, 90, and 180 degrees. The BOB was tested in both bare and helmeted configurations. Data recorded across a bare headform at each angle established a baseline for the pressure trace at each sensor location. Two helmeted cases were investigated: Advanced Combat Helmet (ACH) with the sling suspension system and ACH with Team Wendy pads. Results showed peak pressures on exposed surfaces normal to the blast were similar to 200kPa with side-on pressures of similar to 400kPa. The addition of a helmet did not alter the peak normal pressures, but showed slight to moderate increases in pressure beneath the helmet based on the amount of cushioning present. The sling suspension, which leaves an open gap between the head and helmet, resulted in several recorded amplification points beneath the helmet with the peaks reaching similar to 800kPa. The Team Wendy pads trials, which effectively fill the gap between the head and helmet, showed amplifications with peaks of similar to 500kPa. An additional set of tests was conducted using an ingress barrier positioned between the head and helmet at the brim. Results showed pressures under the helmet that were lower than the bare headform trials. While it was shown that adding a helmet did in fact increase pressures relative to the bare headform case, these amplifications were still far less than the peak pressure exerted on the exposed surfaces of the headform. The data presented herein is the most robust data set to date for pressures exerted on a helmeted headform and is considered applicable to the first 3-5ms of an unconstrained system, during which time motion is minimal.

This research is fundamental to preventing and mitigating injuries sustained by those exposed to dangerous conditions including but not limited to occupational hazards, warfighter risks, automotive accidents, etc. Unlike traditional mechanical system research, biological systems are difficult and costly to test resulting in a need for robust and accurate numerical simulations. Models of the cervical spine are complex, nonlinear systems that must accurately model dynamic loading, large deflections, elastic, and viscoelastic behavior. In addition to individual complexities, population variance in both material properties and shape must be taken into account for accurate injury prediction. As part of a hierarchical validation and verification (V&V) methodology, lateral impact cadaveric cervical spine experiments were compared to a high fidelity statistical shape finite element model (SSFEM) of the cervical spine and head. Specimens were mounted to a sled and accelerated using a pendulum impact with 1, 2, and 3 m/s impact velocities. The kinematics of the head and all individual cervical vertebrae were recorded with a Vicon motion capture system along with sled acceleration data. Sled accelerations were used as input boundary conditions for the probabilistic study using the SSFEM. Head and vertebrae rotations between the experimental and model responses were then compared. A latin hypercube probabilistic analysis was performed for each impact velocity to determine the probabilistic response of each rotation metric. When comparing these responses, both the average and variation must be taken into consideration. This is accomplished using a quantitative validation metric based on the area between the cumulative distribution functions (CDF) of experimental response and the computed probabilistic response. Our results showed a very good match between the model and experiment at the higher impact velocities and a slightly stiffer response at lower rates. These results are consistent with previous validation studies performed with this SSFEM. By expanding the validation data set with lateral impact loading, greater confidence in the model is obtained under different loading modes. This confidence allows the model to be used for probability of injury predictions as well as to identify important system variables in preventing injuries. High fidelity numeric modeling allows for rapid and cost effective assessment of hazardous loading conditions and safety equipment compared to experimental modeling. The knowledge gained from these modeling studies is fundamental and necessary for safe and effective design and injury mitigation.

GP ASME TI Reducing the Effects of Blast to the Head through Load Partitioning SO PROCEEDINGS OF THE ASME INTERNATIONAL MECHANICAL ENGINEERING CONGRESS AND EXPOSITION, 2013, VOL 3A LA English DT Proceedings Paper CT ASME International Mechanical Engineering Congress and Exposition (IMECE2013) CY NOV 15-21, 2013 CL San Diego, CA SP ASME ID TRAUMATIC BRAIN-INJURY AB Warfighters who survive encounters with improvised explosive devices (IEDs) may incur mild traumatic brain injury (mTBI) due to blast overpressure effects. Since existing head injury criteria are mostly based on head kinematics, head acceleration is one key metric to be measured. A blast wave travels at supersonic speed with a very sharp peak overpressure rise followed by a rapid decay within a short duration. For the surface area that is covered by the helmet, the cushion/suspension subsystem is responsible for mitigating the blast effects on the head, while the exposed area of the head or face would receive a direct blast loading. Computational fluid dynamic (CFD) simulations of a blast on an upright warfighter show a significant reduction in peak force to the head when a helmet is worn. For a helmet with an attached eye-shield, the load to the head from a front blast can be reduced further. A field study was conducted to verify that the increased load partitioned away from face and to the helmet and cushioning system would result in decreased head acceleration. Blast field tests were conducted using 4 lbs. of cylindrical C4 charges at 92 '' standoff Head acceleration was measured using combinations of a free hanging mid-size standard ISO headform fitted with Team Wendy (TW) pads, an advanced combat helmet (ACH), and an eye-shield. Tests were performed with the blast hitting the front, side and back of the helmeted headform system. Headform accelerations ranging from 120-465g were recorded based on blast direction and the amount of head protection. To validate the three-dimensional Navier-Stokes' based CFD simulations, a custom-designed blast overpressure bust (BOB) containing 22 surface pressure sensors was mounted on top of the BTD to measure the pressure distribution over the head and face when exposed to a blast. The incident overpressure of the blast was 0.25MPa, with reflected pressures reaching 1.0MPa.

A simplified Rayleigh-Plesset equation is used to obtain the phase change rate from the local pressure. The phase change rate is expressed as mass flux jump conditions. The phase interface is tracked using a second-order volume-of-fluid method with a constructed level set function. The interface normal velocity jump is extended into the flow field using a fast marching method. A ghost fluid method is used to prevent difficulties computing high-order derivatives near the interface. Two separate intermediate velocity fields from the momentum equation are solved considering the velocity jump conditions.

Design: We conducted a retrospective study. Methods: All individuals aged 15 years and older who initiated ART between 2008 and 2010 in Henan Province with completed CTX prophylaxis treatment information were included. The effect of CTX prophylaxis was estimated using Kaplan-Meier survival analysis and multivariate Cox proportional hazard modeling for mortality at 3-months and 12-months after ART initiation. Results: Overall mortality among patients receiving both ART and CTX was nearly double at 3-months after ART initiation compared with that at 12-months (12.4 per 100 PY vs 6.3 per 100 PY, p<0.01). After adjusting for gender, age, TB history, year of ART initiation and CD4 count at ART initiation, CTX was associated with a significant reduction in 12-month mortality (adjusted hazard ratio (AHR) = 0.65, 95% confidence interval (CI): 0.44 - 0.95; p = 0.027) compared with persons not receiving CTX. The protective effect was more pronounced in the first 3 months after ART initiation (AHR = 0.53, 95% CI: 0.32 - 0.89; p = 0.017). Conclusion: CTX prophylaxis together with ART reduced mortality of adult HIV patients during the first 12 months of ART in Henan Province, China. The effect was highest in the first 3 months of ART. CTX should be prescribed to all HIV-infected adults who initiate ART.

The main challenge for optical imaging in turbid water is the collection of light that is scattered multiple times on its path to and from the scene of interest. Sophisticated techniques using pulsed or modulated lasers and gated, high speed photo receivers have been developed to reject scattered light and enhance image quality. Although advancements in laser and receiver hardware have made it possible to reduce the size, weight and power of these laser imaging systems, it is still a significant challenge to make these systems compatible with small, autonomous platforms that are desirable for undersea surveillance. Researchers at NAVAIR have developed a multistatic laser imaging approach where the transmitter(s) and receiver(s) are located on separate, smaller platforms. Each laser illuminator is temporally encoded with information that is used by the receiver(s) to construct an image. Recently, this multistatic configuration was modified so that both 2D (amplitude) and 3D (amplitude and range) underwater imagery was collected. This new system design enables the system to identify low contrast objects that contain distinct range relief features. Results from recent laboratory water tank experiments will be presented to evaluate the performance of this new 3D, multistatic laser imaging system in different water environments.

Both approaches use a combination of multi-frequency and single frequency modulation with the goal of simultaneously providing good range accuracy, unambiguous range, and backscatter suppression. The first approach uses a combination of dual and single frequency modulation. The performance is explored as a function of increasing average frequency while keeping the difference frequency of the dual tones constant. The second approach uses a combination of a stepped multi-tone modulation called frequency domain reflectometry (FDR) and single frequency modulation. The FDR technique is shown to allow simultaneous detection of the range of both the volumetric center of the backscattered "clutter" signal and the desired object. Experimental and simulated results are in good agreement for both techniques and performance out to ten attenuations lengths is reported.

However, as targets get smaller and better camouflaged, new techniques are needed to enhance system sensitivity. Researchers at NAVAIR have been developing several techniques that use RF modulation to suppress background clutter and enhance target detection. One approach in particular uses modulation to encode a pulse in a synchronous line scan configuration. Previous results have shown this technique to be effective at both forward and backscatter suppression. Nearly a perfect analog to modulated pulse radar, this technique can leverage additional signal processing and pulse encoding schemes to further suppress background clutter, pull signals out of noise, and improve image resolution. Additionally, using a software controlled transmitter, we can exploit this flexibility without the need to change out expensive hardware. Various types of encoding schemes were tested and compared. We report on their comparative effectiveness relative to a more conventional non-coded pulse scheme to suppress background clutter and improved target detection.

Among combat amputees, intravenous (IV) morphine (vs IV fentanyl) after injury was associated with reduced likelihood of posttraumatic stress disorder (PTSD). The previous results were based on military health diagnoses over 2 yr postinjury. The present study followed psychological diagnoses of patients with amputation for 4 yr using military and Department of Veterans Affairs health data. In-theater combat casualty records (n = 145) documented Glasgow Coma Scale (GCS) scores and/or morphine, fentanyl, or no opioid treatment within hours of injury. We found that (1) GCS scores were not significantly associated with PTSD; (2) longitudinal modeling using four (yearly) time points showed significantly reduced odds of PTSD for patients treated with morphine (vs fentanyl) across years (adjusted odds ratio = 0.40; 95% confidence interval = 0.17-0.94); (3) reduced PTSD prevalence for morphine (vs IV fentanyl; morphine = 25%, fentanyl = 59%, p < 0.05) was significant, specifically among patients with traumatic brain injury during the first 2 yr postinjury; and (4) PTSD prevalence, but not other disorders (e. g., mood), increased between year 1 (PTSD = 18%) and years 2 through 4 postinjury (PTSD range = 30%-32%).

Recruits completed a confidential survey during their first week of training at the Marine Corps Recruit Depot in San Diego, California. Demographics, behaviors, and health information were analyzed for trends from 2001 to 2010 using the Cochran-Armitage trend test and F statistic. Data from 131,961 male recruits with a mean age of 19.8 years were analyzed. Overall, entry characteristics remained stable exhibiting only modest changes over the study period. Favorable trends included recent (2009-2010) improvements in body mass index and physical activity levels. Unfavorable trends included increases in smokeless tobacco and caffeine use, and angry outbursts. Although many recruit characteristics remained similar over the past decade, both favorable and unfavorable trends in sociobehavioral characteristics were noted. The ongoing assessment of preservice characteristics is important for detecting emerging trends over time. Findings may guide leadership's understanding of changes to help develop early-service trainings promoting a healthier force and potentially reducing future adverse outcomes.

However, little prospective work has examined the risk and protective factors for functional difficulties among Veterans. In a sample of recently separated Marines, we used stepwise logistic and multiple regressions to identify predictors of functional impairment, including work-related problems, financial problems, unlawful behavior, activity limitations due to mental health symptoms, and perceived difficulty reintegrating into civilian life. Posttraumatic stress disorder symptoms assessed both before and after military separation significantly predicted functional difficulties across all domains except unlawful behavior. Certain outcomes, such as unlawful behavior and activity limitations due to mental health symptoms, were predicted by other or additional predictors. Although several forms of functioning were examined, the list was not exhaustive. The results highlight a number of areas where targeted interventions may facilitate the reintegration of military servicemembers into civilian life.

The small-scale arrangement consisted of a 2-g booster and 10-g sample mounted at the closed end of a 127-mm diameter by 4.6-m long steel tube with pressure transducers along its length. The three performance characteristics considered were peak pressure, initial energy release, and impulse. The relative performance from five explosives was compared to that from a 1.16-m diameter by 30-m long tunnel that used 2.27-kg samples. The peak pressure values didn't correlate between the tunnels. Partial impulse for the explosives did rank similarly. The initial energy release was determined from a one-dimensional point-source analysis, which nearly tracked with impulse suggesting additional energy released further down the tunnel for some explosives. This test is a viable tool for optimizing compositional variations for blast performance in target scenarios of similar geometry. C1 [Felts, J. E.; Lee, R.

However, studying energetic materials can be challenging when extracting information from static high-pressure measurements. Energetic materials are traditionally C, H, N, O compounds with low crystalline symmetry, producing weak signal in commonly performed x-ray diffraction measurements. The small sample volume available in a static high-pressure cell exacerbates this issue. Additionally, typical hydrostatic compression media, such as methanol/ethanol, may react with many energetic materials. However, characterization of their thermodynamic parameters and phase stability is critical to understanding explosive performance and sensitivity. Crystalline properties, such as bulk modulus and thermal expansion, are necessary to accurately predict the behaviour of shocked solids using hydrodynamic codes. In order to obtain these values, equations of state of various energetic materials were investigated using synchrotron angle-dispersive x-ray diffraction experiments at static high-pressure and temperature. Intense synchrotron radiation overcomes the weak x-ray scattering of energetic materials in a pressure cell. The samples were hydrostatically compressed using a non-reactive hydrostatic medium and heated using a heated diamond anvil cell. Pressure - volume data for the materials were fit to the Birch-Murnaghan and Vinet formalisms to obtain bulk modulus and its first pressure derivative. Temperature - volume data at ambient pressure were fit to obtain the volume thermal expansion coefficient. Data from several energetic materials will be presented and compared.

Peak quasi-static pressures from five explosive formulations were measured, and energy released per gram was calculated. The smaller test used 12-g charges loaded in a steel holder, while data selected from the larger test was from bare charges between 2.7 and 21 kg. The energies for a given explosive were comparable for each size charge tested in the larger chamber. In the smaller chamber the energies were less, most likely due to heat losses to the holder. Explosives with the highest concentration of explosive ingredients incurred the highest energy losses in the small chamber. The current design of the smaller test provides a reasonable ranking of explosives with similar concentrations of explosive ingredients, thereby validating the use of the test for the newer explosives being assessed. However, it may be possible to obtain consistent rankings for all explosives given a change to the holder design in the smaller test.

To better understand the response of improvised materials or homemade explosives (HMEs) to SSST testing, 16 HME materials were compared to three standard military explosives in a proficiency-type round robin study among five laboratories-two DoD and three DOE-sponsored by DHS. The testing matrix has been designed to address problems encountered with improvised materials-powder mixtures, liquid suspensions, partially wetted solids, immiscible liquids, and reactive materials. More than 30 issues have been identified that indicate standard test methods may require modification when applied to HMEs to derive accurate sensitivity assessments needed for developing safe handling and storage practices. This paper presents a generalized comparison of the results among the testing participants, comparison of friction results from BAM (German Bundesanstalt fur Materialpr fung) and ABL (Allegany Ballistics Laboratory) designed testing equipment, and an overview of the statistical results from the RDX (1,3,5-Trinitroperhydro-1,3,5-triazine) standard tested throughout the proficiency test.

Similar phenomenon has now been observed for the highly insensitive PBXIH-140, whose critical diameter of similar to 100 mm required an even larger gap test with a sample diameter of 178 mm. When just exceeding the critical gap for HVD, LVD propagated at similar velocities as in PBXN-109 and would punch clean holes in a witness plate like HVD. For somewhat greater gaps, there was enough shock reaction to drive LVD at constant but reduced velocities as the input shock decreased to similar to 1/2 of critical. With a different formulation now exhibiting LVD, it may be more prevalent than previously realized. It is speculated to occur in various confinements when small percentages of easily detonable ingredients fail to initiate the remainder of less shock sensitive ingredients. C1 [Sandusky, H.

Two HTPB/Fe compositions were developed, the first without plasticizer and the second containing plasticizer. Samples were tested with and without the application of a 0.01 Tesla magnetic field. Strain gauge data taken from the Split Hopkinson Pressure Bar has been used to determine the extent of change in mechanical properties by inducing a mild electromagnetic field onto each sample. Raw data from strain gages was processed using commercial software (Signo) and Excel spreadsheet. It is of particular interest to determine whether the mechanical properties of binder systems can be manipulated by adding ferrous or Magnetostrictive particulates. Data collected from the Split Hopkinson Pressure bar indicate changes in the Mechanical Stress-Strain curves and suggest that the impedance of a binder system can be altered by means of a magnetic field.

Research design: Clinicians saw US military personnel within 72 hours of sustaining a blast-related mTBI and at a follow-up visit 48-72 hours later (n = 210). Methods and procedures: Demographics, post-concussive symptoms, diagnosis of acute stress reaction (ASR) and simple reaction time data from the Automated Neuropsychological Assessment Metric (ANAM) were collected. Main outcomes and results: ASRs were significantly more likely in patients reporting LOC versus patients reporting no LOC. At the first post-injury visit, LOC was associated with difficulty sleeping, hearing loss, memory problems and reporting more symptoms. A follow-up analysis explored if symptomatic differences were influenced by ASR. Adjusting for ASR, the statistical relationships between LOC and symptoms were weaker (i.e. reduced Odds Ratios). At the follow-up visit, difficulty sleeping was associated with LOC before and after adjusting for ASR. Patients with both ASR and LOC had the slowest simple reaction times. Conclusions: Results suggest ASR may partially mediate symptom presentation and cognitive dysfunction in the acute phase following blast-related mTBI. Future research is warranted.

This human head surrogate fills the void between Post-Mortem Human Subject testing (with biofidelity but handling restrictions) and commercial ballistic head forms (with no biofidelity but ease of use). This unique human head surrogate is based on refreshed human craniums and surrogate materials representing human head soft tissues such as the skin, dura, and brain. A methodology for refreshing the craniums is developed and verified through material testing. A test methodology utilizing these unique human head surrogates is also developed and then demonstrated in a series of experiments in which non-perforating ballistic impact of combat helmets is performed with and without supplemental ceramic appliques for protecting against larger caliber threats. Sensors embedded in the human head surrogates allow for direct measurement of intracranial pressure, cranial strain, and head and helmet acceleration. Over seventy (70) fully instrumented experiments have been executed using this unique surrogate. Examples of the data collected are presented. Based on these series of tests, the Southwest Research Institute (SwRI) Human Head Surrogate has demonstrated great potential for providing insights in to injury mechanics resulting from non-perforating ballistic impact on combat helmets, and directly supports behind helmet blunt trauma studies.

TI Experiments with an ion-neutral hybrid trap: cold charge-exchange collisions SO APPLIED PHYSICS B-LASERS AND OPTICS LA English DT Article ID STATES; ATOMS AB Due to their large trap depths (similar to 1 eV or 10,000 K), versatility, and ease of construction, Paul traps have important uses in high-resolution spectroscopy, plasma physics, and precision measurements of fundamental constants. An ion-neutral hybrid trap consisting of two separate but spatially concentric traps [a magneto-optic trap (MOT) for the neutral species and a mass-selective linear Paul trap for the ionic species] is an ideal apparatus for sympathetic cooling. However, over the past few years, hybrid traps have proven most useful in measuring elastic and charge-exchange rate constants of ion-neutral collisions over a wide temperature range from kilo-Kelvin to nano-Kelvin. We report some initially surprising results from a hybrid trap system in our laboratory where we have loaded the Paul trap with Ca+ ions in the presence of a Na MOT (localized dense gas of cold Na atoms). We find a strong loss of Ca+ ions with MOT exposure, attributed to an exothermic, non-resonant ion-neutral charge-exchange process with an activation barrier, which leads to the formation of Na+ ions. We propose a detailed mechanism for this process. We obtain an estimated measure of the rate constant for this charge exchange of similar to 2 x 10(-11) cm(3)/s, much less than the Langevin rate, which suggests that the Langevin assumption of unit efficiency in the reaction region is not correct in this case.

Participant consent for genetic studies enables randomized trials to examine effects of interventions compared to control in participants with different genotypes. Methods: Unadjusted and multivariate associations between genetic consent rates and participant, study, and consent characteristics in 9573 participants approached for genetics consent in the multicenter Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial, which used a layered genetics consent. Results: Eighty-nine percent of eligible participants consented to genetic studies ("Any Consent") and 64.7% consented to studies of any genes by any investigator ("Full Consent"), with similar rates in randomized groups. Controlling for multiple characteristics, African-Americans had lower consent rates than others (Any Consent Odds Ratio, OR = 0.62, p = 0.0004; Full Consent OR = 0.67, p < 0.0001). Those with high school or higher education level had higher rates than less than high school graduates (Full Consent ORs 1.41-1.69, p-values < 0.0001). Consent rates were lower when genetics consent was separate from the main trial consent on the same day (Any Consent OR 030; Full Consent OR 0.52, p values < 0.0001) or on a subsequent day (Any Consent OR 0.70, p = 0.0022; Full Consent OR 0.76, p = 0.0002). Conclusion: High rates of consent for genetic studies can be obtained in complex randomized trials, with lower consent rates in African-Americans, in participants with less than high-school education, and for sharing samples with other investigators. A genetics consent separated from the main trial consent was associated with lower consent rates. Published by Elsevier Inc.

This comprehensive review of the literature (20012012) examined whether US servicewomen were more likely than men to experience post-traumatic stress disorder (PTSD) after returning from deployments to the Iraq and Afghanistan conflicts. Findings from 18 studies from 8 unique study populations were reviewed. Seven studies found that women had a higher risk for screening positive for PTSD compared with men, including prospectively designed studies that evaluated new-onset PTSD among members from all service branches. Although results from studies with Veterans Affairs samples found women at decreased risk in 4 analyses, these studies used the same source databases, were conducted in treatment-seeking populations, and were mostly unable to account for combat experience. Seven studies detected no differences by gender. In summary, women appeared to have a moderately higher risk for postdeployment PTSD, although there was a lack of consensus among the studies, and even those with the most rigorous methods were not designed specifically to evaluate potential gender differences. Given the limitations of the published literature, further research should use longitudinal study designs and comprehensive evaluations of deployment experiences while adjusting for predeployment factors to confirm that gender differences exist with regard to postdeployment PTSD.

Maximum peak power tracking algorithms, which emphasize high renewable energy utilization, may cause a supply-demand imbalance when the available renewable generation is more than demanded, especially for autonomous microgrids. Currently, droop control is one of the most popular decentralized methods for sharing active and reactive loads among the distributed generators. However, conventional droop control methods suffer from slow and oscillating dynamic response and steady state deviations. To overcome these problems, this paper proposes a distributed subgradient-based solution to coordinate the operations of different types of distributed renewable generators in a microgrid. By controlling the utilization levels of renewable generators, the supply-demand balance can be well maintained and the system dynamic performance can be significantly improved. Simulation results demonstrate the effectiveness of the proposed control solution. C1 [Xu, Yinliang; Zhang, Wei; Liu, Wenxin] New Mexico State Univ, Las Cruces, NM 88001 USA.

Because females may be at higher risk for PTSD development, it is important to evaluate sex differences in acute stress reactions. This study characterized sex differences in cardiovascular and subjective stress reactions among military survival trainees. One hundred and eighty-five military members (78% males) were studied before, during, and 24 h after stressful mock captivity. Cardiovascular (heart rate [HR], systolic blood pressure [SBP], diastolic blood pressure [DBP]) and dissociative states were measured at all three time points. Psychological impact of mock captivity was assessed during recovery. General linear modeling with repeated measures evaluated sex differences for each cardiovascular endpoint, and causal steps modeling was used to explore interrelationships among sex, cardiovascular reactions and psychological impact of mock captivity. Although females had lower SBP than males at all three time points, the difference was most pronounced at baseline and during stress. Accordingly, females showed greater residual elevation in SBP during recovery. Females had lower DBP at all three time points. In addition, females reported greater psychological impact of mock captivity than males. Exploratory causal steps modeling suggested that stress-induced HR may partially mediate the effect of sex on psychological impact of mock captivity. In conclusion, this study demonstrated sex-specific cardiovascular stress reactions in military personnel, along with greater psychological impact of stress exposure in females. This research may elucidate sex differences in PTSD development.

This is because MOGA provides reliable search results covering wide and multi-variable design spaces. Most importantly when an optimization problem involves using mixed design variables, i.e. continuous and discrete variables, MOGA is still applicable. However, in such a condition MOGA needs to be programmed in a binary mode, which requires a minimum number of bits to represent each real and integer design variable. The accuracy of the prediction of the optimization calculation is expected to depend on the number of bits used. This paper introduces such a problem based on a general turbomachinery design problem. The design variables of the centrifugal impeller design consist of discrete and continuous variables. Some puzzling behavior occurred when the optimization calculation was carried out, related to the prediction accuracy when applying different number of bits to represent the continuous and discrete design variables. It is found that the accuracy is independent of the number of binary bits used. Detailed analyses were performed using simplified analytic formulations for the objective functions to determine why the calculated results show such a behavior. In addition, objective functions are developed and verified that do not show this behavior. C1 Carderock Div, Naval Surface Warfare Ctr, West Bethesda, MD 20817 USA.

GP ASME TI A PERFORMANCE PREDICTION MODEL FOR LOW-SPEED CENTRIFUGAL FANS SO PROCEEDINGS OF THE ASME FLUIDS ENGINEERING DIVISION SUMMER MEETING - 2014, VOL 1A: SYMPOSIA LA English DT Proceedings Paper CT 4th ASME Joint US-European Fluids Engineering Diviison Summer Meeting CY AUG 03-07, 2014 CL Chicago, IL SP ASME, Fluids Engn Div AB A generalized model for mapping the trend of the performance characteristics of a double-discharge centrifugal fan is developed based on the work by Casey and Robinson (C&R) which formulated compressor performance maps for tip-speed Mach numbers ranging from 0.4 to 2 using test data obtained from turbochargers with vaneless diffusers. The current paper focuses on low-speed applications for Mach number below 0.4. The C&R model uses four non-dimensional parameters at the design condition including the flow coefficient, the work input coefficient, the tip-speed Mach number and the polytropic efficiency, in developing a prediction model that requires limited geometrical knowledge of the centrifugal turbomachine. For the low-speed fan case, the C&R formulas are further extended to a low-speed, incompressible analysis. The effort described in this paper begins by comparing generalized results using efficiency data obtained from a series of fan measurements to that using the C&R model. For the efficiency map, the C&R model is found to heavily depend on the ratio of the flow coefficient at peak efficiency to that at the choke flow condition. Since choke flow is generally not applicable in the low-speed centrifugal fan operational environment, an alternate, but accurate estimation method based on fan free delivery derived from the fan test data is presented. Using this new estimation procedure, the modified C&R model predicts reasonably well using the double discharge centrifugal fan data for high flow coefficients, but fails to correlate with the data for low flow coefficients. To address this undesirable characteristic, additional modifications to the C&R model are also presented for the fan application at low flow conditions. A Reynolds number correction is implemented in the work input prediction of the C&R model to account for low-speed test conditions. The new model provides reasonable prediction with the current fan data in both work input and pressure rise coefficients. Along with the developments for the efficiency and work input coefficient maps, the use of fan shut-off and free delivery conditions are also discussed for low-speed applications.

Compared to other means of active flow controls, the DBD plasma actuations have several advantages, including absence of moving parts, a fast time response for unsteady applications, a very low mass of the device, no cavities or holes on control surfaces, and possibly low energy consumption. These features are especially important for applications with high g-loads, such as turbomachinery blades rotating at high speed. A computational method has been developed to couple a DBD electro-hydrodynamic (EHD) body force model with the Reynolds averaged Navier-Stokes (RANS) model for incompressible flows. The EHD body force model is based on solving the electrostatic equations for the electric potential due to applied voltage and the net charge density due to ionized air. The boundary condition for charge density on the dielectric surface is obtained from a Space-Time Lumped-Element (STLE) circuit model that accounts for time and space dependence of the air ionization on the input voltage amplitude, frequency, electrode geometry, and dielectric properties. Alternatively, an empirical formulation representing a Gaussian distribution of charge density on the dielectric-surface can also be used. The EHD body force is calculated using the solutions obtained from solving the electric potential and the net charge density equations. As a comparison, a much simpler Linearized Electric Body Force (LEBF) model is also used to directly specify the spatial distribution of the averaged EHD body force. The coupled computational models have been implemented using a multiple-domain approach. The electric potential equation, the net charge density equation, and the flow equations are solved in separate computational domains. All equations are discretized in space using a cell-centered finite volume method. Parallel computation is implemented using domain-decomposition and message passing interface (MPI). Due to a large disparity in time scales between the electric discharge and the flow, a multiple sub-cycle technique is used in coupling the plasma solver and the flow solver. The DBD plasma induced flow in quiescent air is used as a test case and the computational results are validated against experimental measurement. A comparison between different EHD body force models is also presented.

Composites were prepared using molybdenum trioxide (MoO3) and aluminum (Al) fuel particles with and without surface functionalization. The surface functionalization consisted of a 5-nm-thick layer (35% by weight) of perfluorotetradecanoic add (PFTD) bonded to the Al2O3 surface of the Al particles. The first composite consisted of Al functionalized with PFTD and MoO3, the second consisted of Al with MoO3 and added PFTD particles to the same weight percentage as in the Al functionalized PFTD, and the third composite consisted of Al with MoO3. The results showed a dramatic increase in FFV from 100 to 500 m/s resulting from the surface functionalization. The results of the experiments show that the surface functionalized Al composite (Al-PFTD/MoO3) has a reaction rate 2 x than that of the simple Al/MoO3 and 3.5x than that of the Al/MoO3/PFTD composite.

During lithiation of the negative carbon electrode, the electrolyte reacts with the electrode surface and undergoes decomposition to form a solid electrolyte interphase (SEI) layer that passivates the surface of the carbon electrode from further reactions between Li and the electrolyte. The reduction reactions that the solvent undergoes also form insoluble and gaseous by-products. In this work, those gaseous by-products generated by reductive decomposition of a carbonate-based electrolyte, 1.2 M LiPF6 in EC/PC/DEC(3:1:4), were analyzed at different stages during the lithiation process of an amorphous carbon electrode. The stages in the generation of gaseous by-products were determined to come as a result of two, 1-electron reduction steps of the cyclic carbonate components of the electrolyte. Electrochemical impedance spectroscopy was also used to investigate the two distinct electrochemical processes and the development of the two phases of the SEI structure. This is the first time that the state of an electrochemical cell during the formation of the SEI layer has been systematically correlated with theoretical reaction mechanisms through the use of in situ electrochemical-MS and impedance spectroscopy analyses.

The plate may be subjected to inplane or out-of-plane bending loading. Furthermore, the plate may be flat or curved in a cylindrical shape. The model helps to select patch material (i.e., elastic modulus of the material) and the appropriate patch size in order to reduce the SERR at the crack tip of the patched base plate. In other words, the analytical model can be utilized to select the patch material and patch dimensions required to achieve the desired SERR for a cracked base plate with known modulus, thickness, and crack size. The model is based on axial and bending stresses of the single-side strap joint configuration, which are related to the SERR at the crack tip of a plate with a single-side patch repair. In order to verify the analytical model, finite element analyses were conducted to determine stresses as well as SERR in many different patched plates. The numerical study confirmed the validity of the analytical model in predicting the reduction ratio of SERR resulting from the single-side patch repair. C1 [Kwon, Y. W.; Lee, W. Y.; McGee, A.

One hundred sixty-one male participants, aged 18-30, completed two weekly prospective diaries and a retrospective survey querying them about behaviors reported during the same time frame as the diaries. Most reported behaviors were similar between the two data collection methods. However, there was low agreement for reporting sex with a spouse and exchanging material goods for sex with a casual partner; frequency of sex and condom use rates (CURs) among married participants also differed. When comparing survey condom use frequencies to diary CURs, the level of agreement diminished from the always to occasionally condom use categories. Inconsistencies in reporting may be due to the frequency of the sexual behavior, question sensitivity, the data collection setting, and the interpretation of response categories. Further research is needed to improve accurate reporting of sexual behaviors.

First and second generation lithium-ion capacitors were cycled at temperatures ranging from -30 degrees C to 65 degrees C, with rates from 5 degrees C to 200 degrees C. Unlike acetonitrile-based electric double-layer capacitors, whose performance has been reported to be relatively insensitive to temperatures between -30 degrees C and 40 degrees C, lithium-ion capacitor performance degrades at low temperatures and displays characteristics typical of a lithium-ion battery. Three-electrode lithium-ion capacitor cycling tests revealed that reduced capacity at low temperatures is due to the polarization of the lithiated, negative electrode. The self-discharge of cells at the various temperatures was studied and compared to an electric double-layer capacitor and a lithium-ion battery cell. Lithium-ion capacitors and batteries were observed to have significantly lower self-discharge rates than electric double-layer capacitors. Accelerating rate calorimetry and differential scanning calorimetry were used to assess the thermal runaway behavior of full cells along with the thermal properties of the cell components. Our study showed that the thermal behavior of the lithium-ion capacitor is in between those of an electric double-layer capacitor and a lithium-ion battery. Published by Elsevier B.V.

Mass selective resonant quenching (MSRQ) is implemented in LPT either to identify a charged particle's mass or to remove unwanted ions from a controlled experimental environment. In the latter case, MSRQ can introduce undesired heating to co-trapped ions of different mass, whose secular motion is off resonance with the quenching ac field, which we call off-resonance energy absorption (OREA). We present simulations and experimental evidence that show that the OREA increases exponentially with the number of ions loaded into the trap and with the amplitude of the off-resonance external ac field.

TI The Association of Predeployment and Deployment-Related Factors on Dimensions of Postdeployment Wellness in US Military Service Members SO AMERICAN JOURNAL OF HEALTH PROMOTION LA English DT Article DE Wellness; Health Promotion; Military Personnel; Physical Fitness; Combat; Prevention Research ID POSTTRAUMATIC-STRESS-DISORDER; QUALITY-OF-LIFE; READJUSTMENT RATING-SCALE; HEALTH-CARE UTILIZATION; MILLENNIUM COHORT; MENTAL-HEALTH; GENDER-DIFFERENCES; CIGARETTE-SMOKING; PSYCHOMETRIC PROPERTIES; LONGITUDINAL ASSESSMENT AB Purpose. To assess the effects of predeployment and deployment-related factors on dimensions of wellness following deployment. Design. Prospective longitudinal study. The dependent variable was dimensions of wellness. Independent variables were measured in terms of modifiable, nonmodifiable, and military factors, such as sex, race/ethnicity, service branch, smoking status, and combat experience. Setting. A large military cohort participating in the Millennium Cohort Study. Subjects. Included 10,228 participants who deployed in support of the operations in Iraq and Afghanistan. Measures. Dimensions of wellness were measured by using standardized instruments assessing self-reported physical health, mental health, and stress. Covariates were measured by using self-reported and electronic data. Analysis. Factors of postdeployment wellness were assessed by using ordinal logistic regression. Results. Most participants (78.7%) were categorized as "moderately well" post deployment. Significant modifiable predeployment predictors of postdeployment wellness included normal/underweight body mass index (odds ratio [OR] = 1.72, p < .05). Military factors significantly associated with wellness included not experiencing combat (OR = .56, p < .05), member of Air Force (OR = 2.02, p < .05) or Navy/Coast Guard (OR = 1.47, p < .05), and combat specialist occupation (OR = 1.22, p < .05). Conclusion. Multiple modifiable factors associated with postdeployment wellness were identified, which may help inform medical and military leadership on potential strategies to ensure a well force. Those trained in combat roles were more likely to be well post deployment though this apparent benefit was not conferred onto those reporting combat experiences.

The first study group resided in an area with a known Q fever outbreak history (Al Asad, Iraq). Of this population, 7.2% seroconverted for an incidence rate of 10.6 seroconversions per 1,000 person-months. The second population included personnel transiting through Qatar on mid-deployment leave from southwest/central Asia. In this group, we found 2.1% prevalence with 0.92 seroconversions per 1,000 person-months. However, no significant risk factors for Q fever seroconversion were found in either population.

TI Calculation of the Impedance Matrix Inner Integral of the Magnetic-Field Integral Equation to Prescribed Precision SO IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION LA English DT Article DE Impedance-matrix; magnetic-field integral equation (MFIE); method of moments; numerical integration; significant digits; solid-angle integral; Taylor's theorem with a remainder AB We present a new method to evaluate the inner integral of the impedance matrix elements in the traditional Rao-Wilton-Glisson formulation of the method of moments for the magnetic-field integral equation. The evaluation is to a prescribed precision. We show that we can write the inner integral in terms of two scalar integrals: 1) a surface integral over the integration triangle (IT) and 2) a line integral over the boundary of the IT. Just as with the original integral, neither of these integrals can be evaluated analytically. In our method, we bypass this obstacle by replacing the original integrand (modified by a constant phase factor) by its Taylor series and by keeping enough terms to guarantee a number of significant digits in the integration outcome. We have accomplished this for the surface and the line integral. We present a systematic derivation of the formulas for the two integrals and we conduct extensive testing of our results.

HIV prevention research is needed to monitor existing programme, identify areas for modification, and develop new interventions. Correct and consistent condom use is highly effective against HIV. However, use among soldiers is lower than ideal. This study describes condom use behaviours and examines correlates of use in the Botswana Defence Force (BDF). Analyses were based on 211 male BDF personnel, aged 18-30, who completed a cross-sectional survey that collected baseline data for an intervention study. Results showed that 51% of participants reported always using condoms, 35% used condoms most times, and 14% used condoms occasionally/never. Condom use varied by partner type and was typically higher with casual partners in comparison to regular partners. After adjustment for age and marital status, factors associated with lower condom use included excessive alcohol use, perception that using condoms reduce sexual pleasure, and having a trusted partner. However, higher levels of HIV knowledge and reports of being circumcised were protective against lower condom use. HIV interventions aimed at increasing condom use in the BDF should address condom perceptions, alcohol abuse, and issues of trust. Innovative ways to increase condom use in this population should also be explored.

Previous research on the association between deployment-related injury and posttraumatic stress disorder (PTSD) has yielded mixed results. Objectives: To examine the effect of battle injury (BI) relative to non-battle injury (NBI) on the manifestation of PTSD symptoms in military personnel and to assess the demographic, injury-specific, and pre-injury factors associated with PTSD following a BI. Patients and methods: A total of 3403 personnel with deployment-related injury (1777 BI and 1626 NBI) were identified from the Expeditionary Medical Encounter Database. Records were electronically matched to Post-Deployment Health Assessment (PDHA) data completed 1-6 months post-injury. The PTSD screening outcome was identified using a four-item screening tool on the PDHA. Results: Compared to those with NBI, personnel with BI had more severe injuries, reported higher levels of combat exposure, and had higher rates of positive PTSD screen. After adjusting for covariates, personnel with BI were twice as likely to screen positive for PTSD compared to those with NBI (odds ratio [OR], 2.10; 95% confidence interval [CI], 1.60-2.75). In multivariable analysis among battle-injured personnel only, moderate and serious-severe injury (OR, 1.49; 95% CI, 1.12-2.00 and OR, 1.64; 95% CI, 1.01-2.68, respectively), previous mental health diagnosis within 1 year of deployment (OR, 2.69; 95% CI, 1.50-4.81), and previous BI (OR, 1.96; 95% CI, 1.22-3.16) predicted a positive PTSD screen. Conclusions: Military personnel with BI have increased odds of positive PTSD screen following combat deployment compared to those with NBI. Post-deployment health questionnaires may benefit from questions that specifically address whether service members experienced an injury during combat. Published by Elsevier Ltd.

TI Development of a Large-scale Surface Effect Ship Bow Seal Testing Platform SO JOURNAL OF SHIP PRODUCTION AND DESIGN LA English DT Article DE surface effect ship; bow seal; resistance; free surface channel AB A large-scale surface effect ship (SES) bow seal testing platform was constructed by the University of Michigan and is presently being commissioned at the U.S. Navy's Large Cavitation Channel (LCC) in Memphis, TN. Using a recently installed (2008) free-surface forming gate, the test platform is capable of investigating the physics of the two-dimensional planing seal and three-dimensional finger-type bow seal in calm water conditions and at scales relevant to SES designers and numerical modelers. The LCC environment permits extended run times at high Reynolds number and provides unfettered optical access to the seal geometry and flow field. This article describes the development of the testing platform and presents some preliminary results. The test platform is nominally 7.9 m long, 1.52 m wide, and 2.0 m tall and of welded and bolted steel construction. The seals are nominally sized similar to those currently used by the U.S. Navy's Landing Craft Air Cushion class. An extensive measurement suite was integrated with the test platform. The goal was to provide numerical modelers a data set with sufficient spatial and temporal resolution to validate their models of the experiment and, where appropriate, to develop new analytic models. The results of this effort demonstrate a feasible system for investigating surface effect ship seal physics within a large free surface water channel.

This study investigated the rates of comorbid psychiatric diagnoses among 81,720 U.S. Marines, and assessed the relationships between preexisting comorbid disorders and risk of psychiatric hospitalizations and attrition from service. The study used medical, deployment, and personnel records for all Marines who enlisted between 2002 and 2005. The baseline rate of comorbidity was 1.3% for Marines who deployed during the first term of service, and 6.3% for Marines who did not deploy. The most common baseline comorbidity among deployed Marines was mood disorders with anxiety disorders, and mood and adjustment disorders among nondeployed Marines. Logistic regression analyses revealed Marines with comorbid diagnoses before deployment were over three times more likely to attrite (odds ratio = 3.4, p < 0.001) and over five times more likely to be hospitalized for psychiatric symptoms (odds ratio = 5.1, p < 0.001) following deployment than those with no diagnoses. Similar patterns emerged among nondeployers. Outcomes associated with comorbid conditions were substantially worse than outcomes for single conditions. These findings demonstrate that Marines with a history of comorbid psychiatric diagnoses are at a much greater risk for adverse outcomes, specifically attrition from the military and psychiatric hospitalization.

TI Depression and Pain: Independent and Additive Relationships to Anger Expression SO MILITARY MEDICINE LA English DT Article ID MENTAL-HEALTH PROBLEMS; PRIMARY-CARE; TRAIT-ANGER; RISK-TAKING; COMBAT; IRAQ; COMORBIDITY; AFGHANISTAN; EPIDEMIOLOGY; AGGRESSION AB Anger and anger expression (ANGX) are concerns in the U.S. military population and have been linked to stress dysregulation, heart. disease, and poor coping behaviors. Objective: We examined associations between depression, pain, and anger expression among military veterans. Method: Subjects (N = 474) completed a depression scale, a measure of pain across the last 4 weeks, and an ANGX scale. A multiple regression model assessed the independent and additive relationships of depression and pain to ANGX. Results: Almost 40% of subjects met the case definition for either major or minor depression. Subjects reported low-to-moderate levels of pain (mean = 6.3 of possible 20) and somewhat frequent episodes of ANGX. As expected, depression and pain were positively associated (r = 0.42, p < 0.001) and crossover effects of antidepressant and pain medication were shown. Specifically, frequency of antidepressant medication use was inversely associated with pain symptoms (r = 0.20, p < 0.001) and frequency of pain medication use was inversely linked to depressive symptoms (r = 0.21, p < 0.001). In a multiple regression model, depression (beta = 0.58, p < 0.001) and pain (beta = 0.21, p < 0.05) showed independent and additive relationships to ANGX (F = 41.5, p < 0.001, R-adj(2) = 0.31). Conclusions: This study offers empirical support for depression pain comorbidity and elucidates independent and additive contributions of depression and pain to ANGX.

Merrill TI Urinary Tract Calculi in Military Aviators SO AVIATION SPACE AND ENVIRONMENTAL MEDICINE LA English DT Article DE urinary calculi; military personnel; epidemiology; aviator ID STONE DISEASE; NEPHROLITHIASIS; UROLITHIASIS; EPIDEMIOLOGY; PREVALENCE; TIME; RISK AB Background: Urinary tract calculi are a common affliction in the United States and estimates of the adult lifetime risk of developing this condition range from 10 to 15%. Although highly variable, the clinical presentation of someone afflicted with urinary tract calculi typically involves varying degrees of pain, nausea, hematuria, and dysuria. Current disease, as well as a history of urinary tract calculi, is potentially disqualifying for aviation duties in the United States military as well as for commercial aviators. Methods: Utilizing population based data from the Defense Medical Epidemiology Database (DMED), the current descriptive epidemiology of urinary tract calculi among military aviators was examined. Results: Based on the data collected, the overall annual incidence density of urinary tract calculi for DoD personnel is approximately 4.8 events/1000 PY. The overall annual incidence density of urinary tract calculi is slightly lower in aviators as compared to the nonaviator DoD population (4.4 events/1000 PY vs. 4.8 events/1000 PY). Discussion: Even though in-flight incapacitation from this malady is believed to be exceedingly rare, the incidence of urinary tract stones and their related morbidity should remain an important area of clinical focus.

Flaherty, Stephen TI Combat injury coding: A review and reconfiguration SO JOURNAL OF TRAUMA AND ACUTE CARE SURGERY LA English DT Review DE Combat; trauma; injury severity scoring; impairment ID SEVERITY SCORE; SCALE; PREDICTOR; MORTALITY; DEATH; CARE; WAR AB BACKGROUND: The current civilian Abbreviated Injury Scale (AIS), designed for automobile crash injuries, yields important information about civilian injuries. It has been recognized for some time, however, that both the AIS and AIS-based scores such as the Injury Severity Score (ISS) are inadequate for describing penetrating injuries, especially those sustained in combat. Existing injury coding systems do not adequately describe (they actually exclude) combat injuries such as the devastating multi-mechanistic injuries resulting from attacks with improvised explosive devices (IEDs). METHODS: After quantifying the inapplicability of current coding systems, the Military Combat Injury Scale (MCIS), which includes injury descriptors that accurately characterize combat anatomic injury, and the Military Functional Incapacity Scale (MFIS), which indicates immediate tactical functional impairment, were developed by a large tri-service military and civilian group of combat trauma subject-matter experts. Assignment of MCIS severity levels was based on urgency, level of care needed, and risk of death from each individual injury. The MFIS was developed based on the casualty's ability to shoot, move, and communicate, and comprises four levels ranging from "Able to continue mission" to "Lost to military." Separate functional impairments were identified for injuries aboard ship. Preliminary evaluation of MCIS discrimination, calibration, and casualty disposition was performed on 992 combat-injured patients using two modeling processes. RESULTS: Based on combat casualty data, the MCIS is a new, simpler, comprehensive severity scale with 269 codes (vs. 1999 in AIS) that specifically characterize and distinguish the many unique injuries encountered in combat. The MCIS integrates with the MFIS, which associates immediate combat functional impairment with minor and moderate-severity injuries. Predictive validation on combat datasets shows improved performance over AIS-based tools in addition to improved face, construct, and content validity and coding inter-rater reliability. Thus, the MCIS has greater relevance, accuracy, and precision for many military-specific applications. CONCLUSION: Over a period of several years, the Military Combat Injury Scale and Military Functional Incapacity Scale were developed, tested and validated by teams of civilian and tri-service military expertise. MCIS shows significant promise in documenting the nature, severity and complexity of modern combat injury.

Historically, there have been few experimental measurements of the frequency response of the underwater channel, particularly with regard to wireless communication systems. In this work, the frequency response is measured out to 1 GHz over a wide range of water clarities (approximately 1-20 attenuation lengths). Both spatial and temporal dispersions are measured as a function of pointing angle between the transmitter and the receiver. We also investigate the impact of scattering function and receiver field of view. The impact of these results to the link designer is also presented.

However, studies have not thoroughly assessed the potential confounding effects of mental health conditions associated with alterations in sleep.RESEARCH DESIGN AND METHODSWe prospectively assessed the association between sleep characteristics and self-reported incident diabetes among Millennium Cohort Study participants prospectively followed over a 6-year time period. Surveys are administered approximately every 3 years and collect self-reported data on demographics, height, weight, lifestyle, features of military service, sleep, clinician-diagnosed diabetes, and mental health conditions assessed by the PRIME-MD Patient Health Questionnaire and the PTSD Checklist-Civilian Version. Statistical methods for longitudinal data were used for data analysis.RESULTSWe studied 47,093 participants (mean 34.9 years of age; mean BMI 26.0 kg/m(2); 25.6% female). During 6 years of follow-up, 871 incident diabetes cases occurred (annual incidence 3.6/1,000 person-years). In univariate analyses, incident diabetes was significantly more likely among participants with self-reported trouble sleeping, sleep duration <6 h, and sleep apnea. Participants reporting incident diabetes were also significantly older, of nonwhite race, of higher BMI, less likely to have been deployed, and more likely to have reported baseline symptoms of panic, anxiety, posttraumatic stress disorder, and depression. After adjusting for covariates, trouble sleeping (odds ratio 1.21 [95% CI 1.03-1.42]) and sleep apnea (1.78 [1.39-2.28]) were significantly and independently related to incident diabetes.CONCLUSIONSTrouble sleeping and sleep apnea predict diabetes risk independent of mental health conditions and other diabetes risk factors.

METHODS: Electronic International Classification of Diseases data from the US Department of Defense (DoD) Birth and Infant Health Registry were used to identify infants born to military families from 1998 through 2005 (N = 676 827) who met the study definition for AHT. DoD Family Advocacy Program data were used to identify infants with substantiated reports of abuse. Rates within the military were compared with civilian population rates by applying an alternate AHT case definition used in a civilian study. RESULTS: Applying the study definition, the estimated rate of substantiated military AHT was 34.0 cases in the first year of life per 100 000 live births. Using the alternate case definition, the estimated AHT rate was 25.6 cases per 100 000 live births. Infant risk factors for AHT included male sex, premature birth, and a diagnosed major birth defect. Parental risk factors included young maternal age (<21 years), lower sponsor rank or pay grade, and current maternal military service. CONCLUSIONS: This is the first large database study of AHT with the ability to link investigative results to cases. Overall rates of AHT were consistent with civilian populations when using the same case definition codes. Infants most at risk, warranting special attention from military family support programs, include infants with parents in lower military pay grades, infants with military mothers, and infants born premature or with birth defects.

TI Seroepidemiologic investigation of an outbreak of pandemic influenza A H1N1 2009 aboard a US Navy Vessel-San Diego, 2009 SO INFLUENZA AND OTHER RESPIRATORY VIRUSES LA English DT Article DE Disease outbreaks; epidemiology; H1N1 subtype; influenza A virus; military personnel ID VIRUS; SHIP; CHEMOPROPHYLAXIS; INFECTION; CHILDREN; ADULTS AB Background During summer 2009, a US Navy ship experienced an influenza-like illness outbreak with 126 laboratory-confirmed cases of pandemic influenza A (H1N1) 2009 virus among the approximately 2000-person crew. Methods During September 24-October 9, 2009, a retrospective seroepidemiologic investigation was conducted to characterize the outbreak. We administered questionnaires, reviewed medical records, and collected post-outbreak sera from systematically sampled crewmembers. We used real-time reverse transcription-PCR or microneutralization assays to detect evidence of H1N1 virus infection. Results Retrospective serologic data demonstrated that the overall H1N1 virus infection attack rate was 32%. Weighted H1N1 virus attack rates were higher among marines (37%), junior-ranking personnel (34%), and persons aged 19-24 years (36%). In multivariable analysis, a higher risk of illness was found for women versus men (odds ratio [OR]=2.2; 95% confidence interval [CI]: 1.1-4.4), marines versus navy personnel (OR=1.7; 95% CI, 1.0-2.9), and those aged 19-24 versus >= 35 years (OR=3.9; 95% CI, 1.2-12.8). Fifty-three percent of infected persons did not recall respiratory illness symptoms. Among infected persons, only 35% met criteria for acute respiratory illness and 11% for influenza-like illness. Conclusions Approximately half of H1N1 infections were asymptomatic, and thus, the attack rate was higher than estimated by clinical illness alone. Enhanced infection control measures including pre-embarkation illness screening, improved self-reporting of illness, isolation of ill and quarantine of exposed contacts, and prompt antiviral chemoprophylaxis and treatment might be useful in controlling shipboard influenza outbreaks.

Against Aedes aegypti larvae, N-(2,6-dichloro-4-(trifluoromethyl)phenyl)-3,5dinitrobenzamide (le) was the most toxic compound (24 h LC50 1940 nM), while against adults N-(2,6-dichloro-4-(trifluoromethyl)phenyl)-2,2,2-trifluoroacetamide (1c) was most active (24 h LD50 19.182 nM, 0.5 mu L/insect). However, the 24 h LC50 and LD50 values of fipronil against Ae. aegypti larvae and adults were significantly lower: 13.55 nM and 0.787 x 10(-4) nM, respectively. Compound 1c was also active against Drosophila melanogaster adults with 24 h LC50 values of 5.6 and 4.9 mu g/cm(2) for the Oregon-R and 1675 strains, respectively. Fipronil had LC50 values of 0.004 and 0.017 mu g/cm(2) against the two strains of D. melanogaster, respectively. In repellency bioassays against female Ae. aegypti, 2,2,2-trifluoro-N-(2-(trifluoromethyl)phenyl)acetamide (4c) had the highest repellent potency with a minimum effective dosage (MED) of 0.039 mu mol/cm(2) compared to DEET (MED of 0.091 mu mol/cm(2)). Compound N(2-(trifluoromethyl)phenyl)hexanamide (4a) had an MED of 0.091 mu mol/cm(2) which was comparable to DEET. Compound 4c was the most potent fungicide against Phomopsis obscurans. Several trends were discerned between the structural configuration of these molecules and the effect of structural changes on toxicity and repellency. Para- or meta- trifluoromethylphenyl amides with an aromatic ring attached to the carbonyl carbon showed higher toxicity against Ae. aegypti larvae, than ortho- trifluoromethylphenyl amides. Ortho- trifluoromethylphenyl amides with trifluoromethyl or alkyl group attached to the carbonyl carbon produced higher repellent activity against female Ae. aegypti and Anopheles albimanus than meta- or para- trifluoromethylphenyl amides. The presence of 2,6-dichloro- substitution on the phenyl ring of the amide had an influence on larvicidal and repellent activity of para- trifluoromethylphenyl amides. (C) 2013 The Authors.

TI Low-field critical current density in porous MgB2 powders SO PHYSICA C-SUPERCONDUCTIVITY AND ITS APPLICATIONS LA English DT Article DE Sintered MgB2 powders; Critical current density field dependence; Vortex pinning; Superconductor cylinder ID SUPERCONDUCTING DISK AB Porous MgB2 powders are comprised of an ensemble of irregularly shaped constituents. In this work we introduce a model for the critical current density in such powders in the presence of a low external field H (H < 4 T) and in the high-porosity limit, where effects of vortex-lattice elasticity can be neglected and vortex pinning takes place within the powder-constituents. The ensuing critical current-density expression is a product of three decoupled factors: The first sets the scale for the critical current-density magnitude, while the second and third factors contain the field and powder-constituent size-parameters dependencies, respectively. The field dependent factor is of the form H-n and 0.5 <= n <= 1.0, where the limiting exponents n = 0.5 and n = 1.0 correspond to vortex configurations within a powder-constituent of a linear array and a two-dimensional lattice, respectively. For the calculations, we assume for the powder constituent shape a cylinder of arbitrary height and radius, where an external field and a single pinned vortex are aligned in parallel to the cylinder's axis. The exact fields of this configuration are derived. The size-parameters dependence implies enhanced critical current density for a cigar-like shape powder-constituent aligned with the field, and of radius smaller than about three times the penetration depth. These conclusions are consistent with pertaining data. (C) 2013 Elsevier B. V. All rights reserved. C1 Naval Surface Warfare Ctr, Carderock Div, Bethesda, MD 20817 USA.

TI Antibodies to Trichomonas vaginalis surface glycolipid SO SEXUALLY TRANSMITTED INFECTIONS LA English DT Article DE ANTIBODIES; ANTIGEN; GENITAL TRACT INFECT; TRICHOMONAS ID TRITRICHOMONAS-FETUS; BOVINE TRICHOMONIASIS; EPITHELIAL-CELLS; LIPOPHOSPHOGLYCAN; ANTIGEN; PROTEINASES; EXPRESSION; INFECTION AB Background Human trichomoniasis is the most common non-viral sexually transmitted disease, yet immune responses are not well studied. Methods Since the Trichomonas vaginalis lipophosphoglycan (TvLPG) is an important virulence factor, a bank of eight monoclonal antibodies was generated to define the antigen in clinical isolates. The TvLPG-specific antibody response of women who were culture positive (n=33) or negative (n=33) for T vaginalis infection was determined by isotype-specific ELISA. Results The bank of monoclonal antibodies reacted with conserved surface TvLPG epitopes in 27 isolates from pregnant women at their first prenatal visit. Conserved TvLPG epitopes were shown to be surface exposed by immunofluorescence. Sera collected from the same patients at the same time were assayed for specific antibodies. Serum and vaginal secretions from 33 T vaginalis-positive women had statistically higher IgG anti-TvLPG levels than age-matched and race-matched negative controls in the same clinical study (p<0.01). Vaginal IgA anti-TvLPG levels of the women with trichomoniasis were almost significantly higher than controls (p=0.055). Infected women with normal pregnancies had significantly higher vaginal IgG anti-TvLPG values than infected women with adverse outcomes of pregnancy. Conclusions These antibody responses show that infected women can respond to the conserved TvLPG antigen. Since antibodies to trichomonad surface LPG protect in a bovine model of trichomoniasis, the role of these antibodies in the human disease should be investigated. C1 [Bastida-Corcuera, F.

Multivariate logistic regression was used to examine the association between occupation and postdeployment PTSD and depression diagnoses by branch of service. Navy health care specialists had higher odds of new-onset PTSD (odds ratio [OR] 4.53, 95% confidence interval [CI] 2.58-7.94) and depression (OR 2.58, 95% CI 1.53-4.34) compared with Navy functional support/other personnel. In addition, Marine combat specialists had higher odds of new-onset PTSD (OR 1.91, 95% CI 1.48-2.47) and depression (OR 1.36, 95% CI 1.10-1.68) compared with Marine functional support/other personnel. Occupation is associated with the development of new-onset PTSD and depression. The high rates of PTSD and depression among health care specialists warrant further investigation into the potential effects of caregiver stress on mental health.

TI Prospective Study of Avian Influenza Virus Infections among Rural Thai Villagers SO PLOS ONE LA English DT Article ID A H5N1 VIRUS; SWINE WORKERS; UNITED-STATES; SURVEILLANCE; PNEUMONIA; OUTBREAKS; POULTRY; ASSAYS; RISK; PCR AB Background: In 2008, 800 rural Thai adults living within Kamphaeng Phet Province were enrolled in a prospective cohort study of zoonotic influenza transmission. Serological analyses of enrollment sera suggested this cohort had experienced subclinical avian influenza virus (AIV) infections with H9N2 and H5N1 viruses. Methods: After enrollment, participants were contacted weekly for 24mos for acute influenza-like illnesses (ILI). Cohort members confirmed to have influenza A infections were enrolled with their household contacts in a family transmission study involving paired sera and respiratory swab collections. Cohort members also provided sera at 12 and 24 months after enrollment. Serologic and real-time RT-PCR assays were performed against avian, swine, and human influenza viruses. Results: Over the 2 yrs of follow-up, 81 ILI investigations in the cohort were conducted; 31 (38%) were identified as influenza A infections by qRT-PCR. Eighty-three household contacts were enrolled; 12 (14%) reported ILIs, and 11 (92%) of those were identified as influenza infections. A number of subjects were found to have slightly elevated antibodies against avian-like A/Hong Kong/1073/1999(H9N2) virus: 21 subjects (2.7%) at 12-months and 40 subjects (5.1%) at 24-months. Among these, two largely asymptomatic acute infections with H9N2 virus were detected by >4-fold increases in annual serologic titers (final titers 1: 80). While controlling for age and influenza vaccine receipt, moderate poultry exposure was significantly associated with elevated H9N2 titers (adjusted OR = 2.3; 95% CI, 1.04-5.2) at the 24-month encounter. One subject had an elevated titer (1: 20) against H5N1 during follow-up. Conclusions: From 2008-10, evidence for AIV infections was sparse among this rural population. Subclinical H9N2 AIV infections likely occurred, but serological results were confounded by antibody cross-reactions. There is a critical need for improved serological diagnostics to more accurately detect subclinical AIV infections in humans.

The pheromone biosynthesis activating neuropeptide (PBAN)/pyrokinin family is a major group of insect neuropeptides and is well conserved in Insecta. This family of peptides has at least two closely related G-protein-coupled receptors (GPCRs) activated by PBAN and a diapause hormone (DH). They have been shown to control several biological activities including pheromone production and diapause induction in moths. However, beyond some moth species, the biological function(s) of PBAN/pyrokinin peptides are largely unknown although these peptides are found in all insects. In this study we identified and characterized PBAN/pyrokinin peptides and corresponding GPCRs from the mosquito, Aedes aegypti. Ae. aegypti PBAN mRNA encodes four putative peptides including PBAN and DH, and is expressed in females and males during all life stages. The PBAN receptor (PBAN-R) and the DH receptor (DH-R) were functionally expressed and confirmed through binding assays with PBAN and DH peptides. These receptors are differentially expressed from eggs to adults with the relative gene expression of the PBAN-R significantly lower during the 4th instar larval (L4) and pupal (P1-P2) stages compared to the 2nd and 3rd instar larval stages (L2 and L3). However, DH-R expression level is consistently 4-10 times higher than the PBAN-R in the same period, suggesting that PBAN-R is downregulated in the late larval and pupal stages, whereas DH-R stays upregulated throughout all developmental stages. PBAN/pyrokinin mRNA expression remains high in all stages since it produces PBAN and DH peptides. This study provides the foundation for determining the function(s) of the PBAN/pyrokinin peptides in mosquitoes and establishes data critical to the development of methods for disruption of these hormone actions as a novel strategy for mosquito control.

TI Risk Factors Associated With Suicide in Current and Former US Military Personnel SO JAMA-JOURNAL OF THE AMERICAN MEDICAL ASSOCIATION LA English DT Article ID POSTTRAUMATIC-STRESS-DISORDER; NATIONAL-DEATH-INDEX; MILLENNIUM COHORT; SERVICE MEMBERS; PRIMARY-CARE; VITAL STATUS; FOLLOW-UP; PRIME-MD; HEALTH; POPULATION AB IMPORTANCE Beginning in 2005, the incidence of suicide deaths in the US military began to sharply increase. Unique stressors, such as combat deployments, have been assumed to underlie the increasing incidence. Previous military suicide studies, however, have relied on case series and cross-sectional investigations and have not linked data during service with postservice periods. OBJECTIVE To prospectively identify and quantify risk factors associated with suicide in current and former US military personnel including demographic, military, mental health, behavioral, and deployment characteristics. DESIGN, SETTING, AND PARTICIPANTS Prospective longitudinal study with accrual and assessment of participants in 2001, 2004, and 2007. Questionnaire data were linked with the National Death Index and the Department of Defense Medical Mortality Registry through December 31, 2008. Participants were current and former US military personnel from all service branches, including active and Reserve/National Guard, who were included in the Millennium Cohort Study (N = 151 560). MAIN OUTCOMES AND MEASURES Death by suicide captured by the National Death Index and the Department of Defense Medical Mortality Registry. RESULTS Through the end of 2008, findings were 83 suicides in 707 493 person-years of follow-up (11.73/100 000 person-years [95% CI, 9.21-14.26]). In Cox models adjusted for age and sex, factors significantly associated with increased risk of suicide included male sex, depression, manic-depressive disorder, heavy or binge drinking, and alcohol-related problems. None of the deployment-related factors (combat experience, cumulative days deployed, or number of deployments) were associated with increased suicide risk in any of the models. In multivariable Cox models, individuals with increased risk for suicide were men (hazard ratio [HR], 2.14; 95% CI, 1.17-3.92; P = .01; attributable risk [AR], 3.5 cases/10 000 persons), and those with depression (HR, 1.96; 95% CI, 1.05-3.64; P = .03; AR, 6.9/10 000 persons), manic-depressive disorder (HR, 4.35; 95% CI, 1.56-12.09; P = .005; AR, 35.6/10 000 persons), or alcohol-related problems (HR, 2.56; 95% CI, 1.56-4.18; P < .001; AR, 7.7/10 000 persons). A nested, matched case-control analysis using 20: 1 control participants per case confirmed these findings. CONCLUSIONS AND RELEVANCE In this sample of current and former military personnel observed July 1, 2001-December 31, 2008, suicide risk was independently associated with male sex and mental disorders but not with military-specific variables. These findings may inform approaches to mitigating suicide risk in this population.

The present study provides systematic health outcome data to inform decisions on the definitive surgical treatment, namely amputation versus limb salvage, for the most serious leg injuries. METHODS: This was a retrospective analysis of health records for patients who sustained serious lower-extremity injuries in the Iraq and Afghanistan conflicts, 2001 to 2008. Patients had (1) amputation during the first 90 days after injury (early amputees, n = 587), (2) amputation more than 90 days after injury (late amputees, n = 84), or (3) leg-threatening injuries without amputation (limb salvage [LS], n = 117). Injury data and health outcomes were followed up to 24 months. RESULTS: After adjusting for group differences, early amputees and LS patients had similar rates for most physical complications. Early amputees had significantly reduced rates of psychological diagnoses (posttraumatic stress disorder, substance abuse) and received more outpatient care, particularly psychological, compared with LS patients. Late amputees had significantly higher rates of many mental and physical health diagnoses, including prolonged infections and pain issues, compared with early amputees or LS patients. CONCLUSION: Early amputation was associated with reduced rates of adverse health outcomes relative to late amputation or LS in the short term. Most evident was that late amputees had the poorest physical and psychological outcomes. These findings can inform health care providers of the differing clinical consequences of early amputation and LS. These results indicate the need for separate health care pathways for early and late amputees and LS patients. (J Trauma Acute Care Surg. 2013; 75: S247YS254.

CASE: A 22-year-old woman presented with a high-grade Pap test result. Work-up demonstrated cervical intraepithelial neoplasia 3 and vaginal intraepithelial neoplasia 3 with extensive condyloma. She presented 6 months after her initial treatment with recurrent disease and was referred to the immunology department, where she was found to have profound lymphopenia. After further evaluation, idiopathic CD4 lymphocytopenia was diagnosed. CONCLUSION: Idiopathic CD4 lymphocytopenia is a rare acquired immunodeficiency. Although genital dysplasia is common in young women, this case demonstrates the importance of determining other etiologies of recurrent human papillomavirus infections and possible immunodeficiencies that may affect management and outcomes.

TI Influence of Combat Blast-Related Mild Traumatic Brain Injury Acute Symptoms on Mental Health and Service Discharge Outcomes SO JOURNAL OF NEUROTRAUMA LA English DT Article DE combat blast injury; functional outcomes; mental health; traumatic brain injury ID POSTTRAUMATIC-STRESS-DISORDER; PROFESSIONAL FOOTBALL PLAYERS; RECURRENT CONCUSSION; US SOLDIERS; IRAQ; PREDICTORS; REGISTRY; RISK AB Assessment of acute mild traumatic brain injury (mTBI) symptoms after a combat blast could aid diagnosis and guide follow-up care. Our objective was to document acute mTBI symptoms following a combat blast and to examine associations between acute symptoms and mental health and service discharge outcomes. A retrospective cohort study was conducted with 1656 service personnel who experienced a combat blast-related mTBI in Iraq. Acute mTBI symptoms were ascertained from point-of-injury medical records. The associations between acute symptoms and posttraumatic stress disorder (PTSD), postconcussion syndrome (PCS), and type of service discharge were examined. Disability discharge occurred in 11% of patients, while 36% had a non-disability discharge and 52% had no recorded discharge. A PTSD and PCS diagnosis was made in 19% and 15% of the sample, respectively. The most common acute mTBI symptoms were headache (62.8%), loss of consciousness (LOC) (34.5%), and tinnitus (33.2%). LOC was predictive of PTSD (odds ratio [OR] 1.54; 95% confidence interval [CI] 1.18, 2.00) and PCS (OR 2.08; 95% CI 1.56, 2.77), while altered mental status (OR 1.53; 95% CI 1.07, 2.17) and previous blast history (OR 1.83; 95% CI 1.15, 2.90) also were predictive of PCS. While no acute mTBI symptoms were associated with discharge outcomes, injury severity was associated with disability discharge. LOC after blast-related mTBI was associated with PTSD and PCS, and injury severity was predictive of disability discharge. The assessment of cognitive status immediately after a blast could assist in diagnosing mTBI and indicate a need for follow-up care.

Participants completed the Clinician-Administered Dissociative States Scale (CADSS) after a stressful mock-captivity event. They were also asked to indicate whether the dissociative experiences just happened (i.e., spontaneous), or whether they chose to have them happen (i.e., deliberate); and whether they appraised the dissociative experience as helpful (i.e., facilitative) or hurtful (i.e., debilitative) to their ability to cope with the stressful event. A majority (95.4%) endorsed dissociative states during stress. More than half (57.4%) described dissociative experiences as spontaneous, 13.0% as deliberate, and 29.5% endorsed neither. In Special Forces soldiers only, those who endorsed facilitative dissociation exhibited higher total CADSS scores than those who endorsed debilitative dissociation. Seventy-three percent of spontaneous dissociators described the experience as debilitative to coping with stress; conversely, 76% of deliberate dissociators said these experiences facilitated coping with stress. Individuals with prior trauma exposure tended to appraise dissociative states as more debilitative to coping. This research may enhance the fidelity of studies of dissociation constructs and may offer pivot points for prevention and treatment of stress-related disorders.

TI Broad-Spectrum Biosensor Capable of Detecting and Identifying Diverse Bacterial and Candida Species in Blood SO JOURNAL OF CLINICAL MICROBIOLOGY LA English DT Article ID IONIZATION MASS-SPECTROMETRY; UNIVERSAL BIOSENSOR; MULTILOCUS PCR; IDENTIFICATION; MICROBIOLOGY; SPECIMENS AB We describe an assay which uses broad-spectrum, conserved-site PCR paired with mass spectrometry analysis of amplicons (PCR/electrospray ionization-mass spectrometry [ESI-MS]) to detect and identify diverse bacterial and Candida species in uncultured specimens. The performance of the assay was characterized using whole-blood samples spiked with low titers of 64 bacterial species and 6 Candida species representing the breadth of coverage of the assay. The assay had an average limit of detection of 100 CFU of bacteria or Candida per milliliter of blood, and all species tested yielded limits of detection between 20 and 500 CFU per milliliter. Over 99% of all detections yielded correct identifications, whether they were obtained at concentrations well above the limit of detection or at the lowest detectable concentrations. This study demonstrates the ability of broad-spectrum PCR/ESI-MS assays to detect and identify diverse organisms in complex natural matrices that contain high levels of background DNA.

MethodsConsenting active-duty male RDF personnel, aged 21years, completed an anonymous sexual risk survey linked to HIV rapid testing that included standardised assessments for PTSD (PCL-M), depression (CES-D) and alcohol use (AUDIT). PTSD and depression prevalence were calculated (data available for 1238 and 1120 participants, respectively), and multivariable regression analyses were conducted. Results22.5% screened positive for depression, 4.2% for PTSD and 3.4% for both. In adjusted analyses, odds of either depression or PTSD were significantly higher in participants reporting STI symptoms (OR=2.27, 2.78, respectively) and harmful alcohol use (OR=3.13, 3.21, respectively). Sex with a high-risk sex partner, lower rank and never deploying were also significantly associated with depression in adjusted analyses. ConclusionsNearly one-fourth of RDF participants screened positive for PTSD or depression, which impacts sexual risk behaviour, HIV acquisition risk and military readiness. Findings may extend to other deploying militaries and provide additional evidence of an association between mental health status and sexual risk behaviour. Effective mental health treatment interventions that also include alcohol use assessments, STI identification/treatment and sexual risk behaviour reduction are needed.

Materials include undoped, 1%, 1.5%, 2%, 4%, 6%, and 10% at. Nd doped polycrystalline YAG and undoped and 1% at. Nd doped single crystal YAG. The motivation of this paper is to determine the ideal material type and doping percentage gain media for use in a high energy 0.946 mu m Nd: YAG laser. Room temperature transmittance measurements for all samples are performed between the midinfrared and ultraviolet edges of absorption. From this calibrated transmittance data, an extinction coefficient and extinction cross section are calculated across the entire spectra. We determine that, for the doping percentages measured, the extinction cross section is independent of doping level. Our measured extinction cross sections are consistent with previously reported values. Temperature dependent transmittance measurements are conducted on 1% and 6% polycrystalline Nd: YAG material. A classical oscillator model for the diode pump band absorption coefficient is presented. A comparison of strengths and weaknesses of single crystal and polycrystalline is presented. This comparison reveals areas of parasitic absorption in polycrystalline YAG. C1 [Springer, Ryan M.] Naval Air Warfare Ctr, Div Aircraft, Patuxent River, MD 20670 USA.

A major challenge in cohort studies is recruiting individuals representative of the targeted sample population to ensure the generalizability of the study's findings. Methods: We evaluated nearly 350,000 invited subjects (from 2004-2008) of the Millennium Cohort Study, a prospective cohort study of the health of US military personnel, for factors prior to invitation associated with study enrollment. Multivariable logistic regression was utilized, adjusting for demographic and other confounders, to determine the associations between both deployment experience and prior healthcare utilization with enrollment into the study. Results: Study enrollment was significantly greater among those who deployed prior to and/or during the enrollment cycles or had at least one outpatient visit in the 12 months prior to invitation. Mental disorders and hospitalization for more than two days within the past year were associated with reduced odds of enrollment. Conclusions: These findings suggest differential enrollment by deployment experience and health status, and may help guide recruitment efforts in future studies.

Objectives: In response to elevated rates of influenza-like illness among U. S. military base camps in Kuwait, U. S. Naval Medical Research Unit No. 3 partnered with local U. S. Army medical units to conduct an A(H1N1) pdm09 outbreak investigation. Patients/Methods: Initial clinical data and nasal specimens were collected via the existent passive surveillance system and active surveillance was conducted using a modified version of the World Health Organization/U.S. Centers for Disease Control and Prevention influenza-like illness case definition [fever (T > 100.5 degrees F/38 degrees C) in addition to cough and/or sore throat in the previous 72 hours] as the screening criteria. Samples were tested via real-time reverse-transcription PCR and sequenced for comparison to global A(H1N1) pdm09 viruses from the same time period. Results: The screening criteria used in Kuwait proved insensitive, capturing only 16% of A(H1N1) pdm09-positive individuals. While still not ideal, using cough as the sole screening criteria would have increased sensitivity to 73%. Conclusions: The results of and lessons learned from this outbreak investigation suggest that pandemic influenza risk management should be a dynamic process (as information becomes available regarding true attack rates and associated mortality, screening and isolation criteria should be re-evaluated and revised as appropriate), and that military operational environments present unique challenges to influenza surveillance.

Although some countries are successfully scaling up VMMC, not all are doing this. When VMMC scale-up experiences are viewed in the context of models for the diffusion of innovation, some important themes emerge. Successful VMMC programs have in common locally led campaigns, a cultural tolerance of VMMC, strong political leadership and coordination, and adequate human and material resources. Challenges with VMMC scale-up have been marked by less flexible implementation models that seek a full-integration of VMMC services at public medical facilities and by struggles to achieve geographic parity in access to care. Innovation diffusion models, especially the endogenous technology model, and multiple levels of influence on diffusion-individual males and their sex partners, communities, and health systems-remind us that the adoption of a prevention intervention, such as VMMC, is expected to start out slowly and, as information spreads, gradually speed up. In addition, the diffusion models suggest that customizing approaches to different populations is likely to accelerate VMMC scale-up and help achieve a long-term, sustainable impact on the HIV epidemic.

A brief description of the theoretical basis and risk assessment in CADET is presented. Validation comparisons between CADET predictions and field measurements of wave-induced vertical motions at Ambrose Channel, New York, are presented. Prototype ship motions were measured with a differential global positioning system in April 1998 along three 488-m-long reaches. Comparisons were made with six ships, three tankers and three containerships, during inbound and outbound transits. In general, the CADET predictions matched the field measurements reasonably well, especially considering the wave heights were relatively small during the measurement period.

This system is capable of acquiring a two-dimensional projection with a 225 cm 2 area of measurement through 21 cm of water. The images can be acquired at rates on the order of 1 kHz. Common sources of error in X-ray imaging, such as X-ray scatter, image distortion, veiling glare, and beam hardening, were considered and mitigated. The measured average void fraction was compared successfully to that of a phantom target and found to be within 1 %. To evaluate the performance of the new system, the flow in and downstream of a ventilated nominally two-dimensional partial cavity was investigated and compared to measurements from dual-tip fiber optical probes and high-speed video. The measurements were found to have satisfactory agreement for void fractions above 5 % of the selected void fraction measurement range.

Performance of a complete IPE system can be determined from the knowledge of the performance characteristics of the IPE subsystems, or components. Here, particle penetration characteristics of a cylindrical-shaped component, consisting of an outer fabric sleeve enclosing an inner appendage, were studied as a function of particle size and ambient wind conditions. A component particle penetration model was developed by combining a potential flow model to calculate flow through and around a component with a filtration model. The filtration model combines classical filtration theory with simple bench-top experiments to determine net particle penetration. The component model predictions of particle penetration through a cylindrical component suggest that its filtration performance is strongly dependent on particle size and ambient wind velocities. To test model predictions, wind-tunnel experiments were conducted over an ambient wind velocity range of 10-80 mph (5-40m s(-1)) and particle diameter range of 10nm to 2m. The experimental results validated model predictions of particle penetration through a cylindrical component. The component model can be extended to model the integrated IPE system considering it to be composed of a combination of cylindrical components.

Design: Longitudinal cohort study. Setting: The Millennium Cohort Study survey is administered via a secure website or US mail. Participants: Data were from 15,204 participants who completed their first deployment between the submissions of 2 consecutive Millennium Cohort questionnaires (2001-2008). Interventions: N/A. Measurements and Results: Using self-reported data from the Millennium Cohort Study we evaluated the association of predeployment sleep duration and insomnia symptoms on the development of new-onset mental disorders among deployers. Multivariable logistic regression was used to estimate the odds of developing posttraumatic stress disorder (PTSD), depression, and anxiety, while adjusting for relevant covariates including combat-related trauma. The study outcomes were assessed using validated instruments, including the PTSD checklist-civilian version, and the PRIME-MD Patient Health Questionnaire. We identified 522 people with new-onset PTSD, 151 with anxiety, and 303 with depression following deployment. In adjusted models, combat-related trauma and predeployment insomnia symptoms were significantly associated with higher odds of developing posttraumatic stress disorder, depression, and anxiety postdeployment. Conclusions: Sleep characteristics, especially insomnia symptoms, are related to the development of mental disorders following military deployments. Assessment of insomnia symptoms predeployment may help to better identify those at highest risk for subsequent adverse mental health outcomes.

The study's aim is to evaluate the prognostic utility of the ANAM4 TBI. In 165 concussed active duty personnel (all ultimately returned to duty) seen and tested on the ANAM4 TBI on days 3 and 5 (median times) from their injury, Spearman's rho statistics showed that all performance subtests (at day 5) were associated with fewer days return-to-duty (RTD) time, whereas concussion history or age did not. Kruskal Wallis statistics showed that ANAM4 TBI, loss of consciousness, and post-traumatic amnesia were associated with increased RTD time; ANAM4 TBI reaction time-based subtests, collectively, showed the largest effect sizes. A survival analysis using a Kaplan-Meier plot showed that the lowest 25% on the reaction time-based subtests had a median RTD time of 19 days, whereas those in the upper 25% had a median RTD time of approximately 7 days. Results indicate that until validated neurocognitive testing is introduced, the ANAM4 TBI battery, especially reaction time-based tests, has prognostic utility.

CA Millennium Cohort Study Team TI Combat Deployment Is Associated with Sexual Harassment or Sexual Assault in a Large, Female Military Cohort SO WOMENS HEALTH ISSUES LA English DT Article ID HEALTH-CARE UTILIZATION; WOMEN VETERANS; HEART-DISEASE; PREVALENCE; MULTIMORBIDITY; AFGHANISTAN; SLEEP; IRAQ AB Background: Previous studies have examined the prevalence, risk factors, and health correlates of sexual stressors in the military, but have been limited to specific subpopulations. Furthermore, little is known about sexual stressors' occurrence and their correlates in relation to female troops deployed to the current operations in Iraq and Afghanistan. Methods: Using longitudinal data from Millennium Cohort participants, the associations of recent deployment as well as other individual and environmental factors with sexual harassment and sexual assault were assessed among U. S. female military personnel. Multivariable analyses were used to investigate the associations. Findings: Of 13,262 eligible participants, 1,362 (10.3%) reported at least one sexual stressor at follow-up. Women who deployed and reported combat experiences were significantly more likely to report sexual harassment (odds ratio [OR], 2.20; 95% confidence interval [CI], 1.84-2.64) or both sexual harassment and sexual assault (OR, 2.47; 95% CI, 1.61-3.78) compared with nondeployers. In addition, significant risk factors for sexual stressors included younger age, recent separation or divorce, service in the Marine Corps, positive screen for a baseline mental health condition, moderate/severe life stress, and prior sexual stressor experiences. Conclusions: Although deployment itself was not associated with sexual stressors, women who both deployed and reported combat were at a significantly increased odds for sexual stressors than other female service members who did not deploy. Understanding the factors associated with sexual stressors can inform future policy and prevention efforts to eliminate sexual stressors. Copyright (C) 2013 by the Jacobs Institute of Women's Health.

We conducted a multi-center, randomized, double-blind, placebo-controlled phase 3 study of the new vaccine to assess its safety and efficacy. Healthy adults at two basic training sites were randomly assigned to receive either vaccine (two enteric-coated tablets consisting of no less than 4.5 log(10) TCID50 of live ADV-4 or ADV-7) or placebo in a 3:1 ratio. Volunteers were observed throughout the approximate eight weeks of their basic training and also returned for four scheduled visits. The primary endpoints were prevention of febrile ARD due to ADV-4 and seroconversion of neutralizing serum antibodies to ADV-7, which was not expected to circulate in the study population during the course of the trial. A total of 4151 volunteers were enrolled and 4040 (97%) were randomized and included in the primary analysis (110 were removed prior to randomization and one was removed after randomization due to inability to swallow tablets). A total of 49 ADV-4 febrile ARD cases were identified with 48 in the placebo group and 1 in the vaccine group (attack rates of 4.76% and 0.03%, respectively). Vaccine efficacy was 99.3% (95% CI, 96.0-99.9; P<0.001). Seroconversion rates for vaccine recipients for ADV-4 and ADV-7 were 94.5% (95% Cl, 93.4-95.5%) and 93.8% (95% CI: 93.4-95.2%), respectively. The vaccine was well tolerated as compared to placebo. We conclude that the new live, oral ADV-4 and ADV-7 vaccine is safe and effective for use in groups represented by the study population.

TI Effect of Load Carriage on Lumbar Spine Kinematics SO SPINE LA English DT Article DE low back pain; backpack; military; load carriage; MRI; upright MRI; lumbar spine kinematics ID LOW-BACK-PAIN; IN-VIVO; MEDICAL ASPECTS; AXIAL LOAD; CURVATURE; POSTURE; SCOLIOSIS; DIAGNOSIS; RESPONSES; ROTATION AB Study Design. Feasibility study on the acquisition of lumbar spine kinematic data from upright magnetic resonance images obtained under heavy load carrying conditions. Objective. To characterize the effect of the load on spinal kinematics of active Marines under typical load carrying conditions from a macroscopic and lumbar-level approach in active-duty US Marines. Summary of Background Data. Military personnel carry heavy loads of up to 68 kg depending on duty position and nature of the mission or training; these loads are in excess of the recommended assault loads. Performance and injury associated with load carriage have been studied; however, knowledge of lumbar spine kinematic changes is still not incorporated into training. These data would provide guidance for setting load and duration limits and a tool to investigate the potential contribution of heavy load carrying on lumbar spine pathologies. Methods. Sagittal T-2 magnetic resonance images of the lumbar spine were acquired on a 0.6-T upright magnetic resonance imaging scanner for 10 active-duty Marines. Each Marine was scanned without load (UN1), immediately after donning load (LO2), after 45 minutes of standing (LO3) and walking (LO4) with load, and after 45 minutes of side-lying recovery (UN5). Custom-made software was used to measure whole spine angles, intervertebral angles, and regional disc heights (L1-S1). Repeated measurements analysis of variance and post hoc Sidak tests were used to identify significant differences between tasks (alpha = 0.05). Results. The position of the spine was significantly (P < 0.0001) more horizontal relative to the external reference frame and lordosis was reduced during all tasks with load. Superior levels became more lordotic, whereas inferior levels became more kyphotic. Heavy load induced lumbar spine flexion and only anterior disc and posterior intervertebral disc height changes were observed. All kinematic variables returned to baseline levels after 45 minutes of side-lying recovery. Conclusion. Superior and inferior lumbar levels showed different kinematic behaviors under heavy load carrying conditions. These findings suggest a postural, lumbar flexion strategy aimed at centralizing a heavy posterior load over the base of support.

TI Comparison of Measured Ship Squat with Numerical and Empirical Methods SO JOURNAL OF SHIP RESEARCH LA English DT Article DE ship squat; numerical models; empirical formulas; ship measurements AB The Beck, Newman and Tuck (BNT) numerical predictions are used in the Coastal and Hydraulics Laboratory (CHL) Channel Analysis and Design Evaluation Tool (CADET) model for predicting underkeel clearance (UKC) resulting from ship motions and squat. The Ankudinov empirical squat prediction formula has been used in the CHL ship simulator and was recently updated. The World Association for Waterborne Transport Infrastructure (formerly The Permanent International Association of Navigation Congresses, PIANC) has recommended several empirical and physics-based formulas for the prediction of ship squat. Some of the most widely used formulas include those of Barrass, Eryuzlu, Huuska, ICORELS, Romisch, Tuck, and Yoshimura. The purpose of this article is to compare BNT, Ankudinov, and PIANC predictions with measured DGPS squat data from the Panama Canal for four ships. These comparisons demonstrate that the BNT, Ankudinov, and PIANC predictions fall within the range of squat measurements and can be used with confidence in deep draft channel design.

Overall prevalence was 2.6 % (95 % CI: 1.84-3.66); personnel who were divorced, separated or widowed, served a parts per thousand yen6 years, never deployed, uncircumcised, reported STI symptoms, had a parts per thousand yen6 lifetime sex partners, or screened positive for harmful alcohol use (via Alcohol Use Disorders Identification Test) had higher HIV prevalence. Ever being divorced, separated or widowed (OR = 29.8; 95 % CI: 5.5-159.9), and STI symptoms (OR = 3.4; 95 % CI: 1.5-7.6) were significantly associated with infection, after multivariable adjustment, while circumcision was protective (OR = 0.4; 95 % CI: 0.2-0.9). Despite mobility and other factors that uniquely influence HIV transmission in militaries, RDF prevalence was similar to the general population. A reason for this finding may be conservative sexual behavior combined with effective leadership-supported prevention programs. Data suggest a concentrated rather than generalized epidemic, with targets identified for intervention.

Methods Former US active duty military service members participating in the Millennium Cohort Study, a population-based sample of US military personnel that began in July of 2001, were prospectively followed from the time of baseline health reporting to self-reported employment status after military separation. Results Of the 9099 separated personnel meeting inclusion criteria, 17% reported unemployment after military service. In multivariable modelling, prior deployment experiences, with or without reported combat, and post-traumatic stress disorder (PTSD) were not significantly associated with employment status postservice. Among those who routinely retired from service with a pension, positive screens for depression (OR, 1.67; 95% CI, 1.05 to 2.63) and panic/anxiety (OR, 1.63; 95% CI, 1.10 to 2.43) were significantly associated with subsequent unemployment. Poor physical health, female sex, black race, lower education and disabling illnesses/injuries were also predictive of postservice unemployment. Conclusions After stratifying for reason for military separation, mental disorders like depression or panic/anxiety and poor physical health may have greater impact than prior deployment experiences or PTSD on the ability to find or maintain employment postservice. These findings may guide support for veterans most in need of job placement services after military service.

Although apathy is a risk factor for dementia, its causes and clinical correlates have not been adequately studied. In particular, side of onset of disease, though a likely predictor of apathy and dementia, has not been thoroughly investigated. Methods: A total of 30 mid-stage patients with PD and 35 community-dwelling elderly control patients (CPs) were administered the AES (self version) along with a battery of cognitive and neuropsychiatric assessments. Persons close to patients with PD and CPs completed the AES-other (informant) version about the patient or CP. Multiple linear regression analysis examined predictors of apathy severity after controlling for mood, levodopa dosage equivalents (LDEs), gender, age, and disease severity (Hoehn-Yahr [H-Y] stage). Results: Patients with right-onset disease more frequently exhibited apathy and evidenced significantly higher total AES scores than left-onset patients with PD or CPs (P < .03). Of all the patients, 42% with right-onset PD versus 11.1% of the patients with left-onset PD exhibited clinically significant levels of apathy. There were no differences for self versus informant scores for right-onset patients with PD. The AES scores were not correlated with depression, stress, anxiety, LDEs, gender, age, and H-Y stage. There were no gender differences for any AES variables. Conclusion: Clinically significant levels of apathy are much more likely to occur in patients with right-onset disease. These patients may be at greater risk of PD-related dementia. C1 [Harris, Erica] USN, Dept Behav Sci & Epidemiol, Hlth Res Ctr, San Diego, CA 92106 USA.

TI A comparison of the PRIME-MD PHQ-9 and PHQ-8 in a large military prospective study, the Millennium Cohort Study SO JOURNAL OF AFFECTIVE DISORDERS LA English DT Article DE Depression; Epidemiology; Assessment/diagnosis; Measurement/psychometrics; Mood disorders ID POSTTRAUMATIC-STRESS-DISORDER; PRIMARY-CARE; SUICIDAL IDEATION; MAJOR DEPRESSION; MENTAL-DISORDERS; HEALTH; VALIDITY; AFGHANISTAN; VALIDATION; VETERANS AB Background: In light of increased concerns about suicide in the military, institutional review boards have mandated increased scrutiny of the final item on the depression screening tool, the PHQ-9, which asks about suicidal thoughts. Since real-time monitoring of all individual responses in most observational studies is not feasible, many investigators have adopted the PHQ-8, choosing to remove the ninth item. This study compares the performance of the PHQ-8 with the PHQ-9 in a population-based sample of military or nonmilitary subjects. Methods: The Millennium Cohort Study administers a self-reported questionnaire that includes the PHQ-9 at 3-year intervals to current and former U.S. military personnel. PHQ-9 responses of 143,705 Millennium Cohort members were investigated. Cross-sectional comparisons of the PHQ-9 and PHQ-8 and prospective analyses to detect a 5-unit change in these measures were performed. Results: Greater than substantial agreement was found between the PHQ-8 and 9 instruments (kappas, 0.966-0.974 depending on survey cycle). There was similarly high agreement between the PHQ-8 and 9 in detecting a 5-point increase (kappa=0.987) or decrease (kappa=0.984) in score. Limitations: One potential limitation of this study is that participants completed the PHQ-9, and PHQ-8 scores were extrapolated from the PHQ-9. In addition, the Millennium Cohort may not fully represent the U.S. military; though previous evaluations have shown the cohort to be a well-representative sample. Conclusions: Since excellent agreement was detected between the PHQ-8 and PHQ-9 instruments, the PHQ-8 would capture nearly all the same cases of depression as the PHQ-9 in populations similar to the one in this study.

The objective of this longitudinal investigation was to identify predictors of psychiatric disorders among Marines who deployed to combat in Iraq and Afghanistan. Methods: The study sample consisted of 1113 Marines who had deployed to Iraq or Afghanistan. Demographic and psychosocial predictor variables from a survey that all Marines in the sample had completed were studied in relation to subsequent psychiatric diagnoses. Univariate and multivariate logistic regression were used to determine the influence of the predictors on the occurrence of psychiatric disorders. Results: In a sample of Marines with no previous psychiatric disorder diagnoses, 18% were diagnosed with a new-onset psychiatric disorder. Adjusting for other variables, the strongest predictors of overall psychiatric disorders were female gender, mild traumatic brain injury symptoms, and satisfaction with leadership. Service members who expressed greater satisfaction with leadership were about half as likely to develop a mental disorder as those who were not satisfied. Unique predictors of specific types of mental disorders were also identified. Conclusions: Overall, the study's most relevant result was that two potentially modifiable factors, low satisfaction with leadership and low organizational commitment, predicted mental disorder diagnoses in a military sample. Additional research should aim to clarify the nature and impact of these factors on combatant mental health.

Herein, for the first time, the curing of a cyanate ester via thermal frontal polymerization is described with two different external heat sources. However, issues of bubbling due to vaporization of the amine catalyst generally resulted in incomplete frontal polymerization when a soldering iron was used as the external heat source. To counter this issue, dual-strip polymerization systems were used, wherein the heat from the exothermic polymerization of a free-radical system was used to initiate the frontal polymerization of a cyanate ester system with an amine catalyst. As a result, complete frontal polymerization occurred. Additionally, the effect of the width of the acrylate strip and its impact on the front temperature, initial velocity, and steady-state velocity of the adjacent cyanate ester system were studied.

TI Detecting Rickettsia parkeri Infection from Eschar Swab Specimens SO EMERGING INFECTIOUS DISEASES LA English DT Article ID SPOTTED-FEVER; UNITED-STATES; TICK; TYPHUS; PCR AB The typical clinical presentation of several spotted fever group Rickettsia infections includes eschars. Clinical diagnosis of the condition is usually made by analysis of blood samples. We describe a more sensitive, noninvasive means of obtaining a sample for diagnosis by using an eschar swab specimen from patients infected with Rickettsia parkeri.

TI Crackle Noise in Heated Supersonic Jets SO JOURNAL OF ENGINEERING FOR GAS TURBINES AND POWER-TRANSACTIONS OF THE ASME LA English DT Article ID SIMULATION AB Crackle noise from heated supersonic jets is characterized by the presence of strong positive pressure impulses resulting in a strongly skewed far-field pressure signal. These strong positive pressure impulses are associated with N-shaped waveforms involving a shocklike compression and, thus, is very annoying to observers when it occurs. Unlike broadband shock-associated noise which dominates at upstream angles, crackle reaches a maximum at downstream angles associated with the peak jet noise directivity. Recent experiments (Martens et al., 2011, "The Effect of Chevrons on Crackle-Engine and Scale Model Results," Proceedings of the ASME Turbo Expo, Paper No. GT2011-46417) have shown that the addition of chevrons to the nozzle lip can significantly reduce crackle, especially in full-scale high-power tests. Because of these observations, it was conjectured that crackle is associated with coherent large scale flow structures produced by the baseline nozzle and that the formation of these structures are interrupted by the presence of the chevrons, which leads to noise reduction. In particular, shocklets attached to large eddies are postulated as a possible aerodynamic mechanism for the formation of crackle. In this paper, we test this hypothesis through a high-fidelity large-eddy simulation (LES) of a hot supersonic jet of Mach number 1.56 and a total temperature ratio of 3.65. We use the LES solver CHARLES developed by Cascade Technologies, Inc., to capture the turbulent jet plume on fully-unstructured meshes.

Smeets, Tom TI Delayed memory effects after intense stress in Special Forces candidates: Exploring path processes between cortisol secretion and memory recall SO STRESS-THE INTERNATIONAL JOURNAL ON THE BIOLOGY OF STRESS LA English DT Article DE Delayed recall; glucocorticoids; immediate recall; multiple mediation; real-life stress; Rey-Osterrieth Complex Figure ID HEALTHY-YOUNG MEN; DECLARATIVE MEMORY; SALIVARY CORTISOL; NEUROPEPTIDE-Y; RETRIEVAL; HUMANS; CONSOLIDATION; PERFORMANCE; MEDIATION; HARDINESS AB The aim of this paper is twofold. First, it explores delayed effects of high endogenously evoked cortisol concentrations on visuo-spatial declarative memory. Subsequently, it applies multiple mediation (MM) analyses to reveal path processes between stress and cognitive performance in a sample of 24 male Special Forces (SF) candidates (mean age = 27.0 years, SD = 4.1). The SF candidates were randomly assigned to a control (n = 12) or an intense stress group (n = 12), and cortisol secretion for the intense stress condition was triggered by a brusque 60 min prisoner of war exercise. Stress exposure provoked robust increases in cortisol concentrations and a significant decline in immediate recall performance, measured with the Rey-Osterrieth Complex Figure (ROCF). The relative retrieval differences in regard to the ROCF persisted even after a recovery period of 24 h, as both groups showed similar levels of memory decline over 24 h. Next, the study applied a MM design that involved distribution-independent asymptotic and resampling strategies to extend traditional bivariate analyses. MM results showed that ROCF performance was mediated by increases in cortisol concentrations. Considering the studied variables, the current analysis was the first to provide statistical support for the generally accepted thesis that cortisol secretion in itself, rather than subjective strain or the experimental treatment, affects cognitive performance. The revelation of such path processes is important because it establishes process identification and may refine existing paradigms.
