In particular, the effects of the primary blast pressure wave are poorly understood. Animal models have proven invaluable for the study of primary bTBI, because it rarely occurs in isolation in human subjects. Even less is known about the effects of repeated primary blast wave exposure, but existing data suggest cumulative increases in brain damage with a second blast. MRI and, in particular, diffusion tensor imaging (DTI), have become important tools for assessing bTBI in both clinical and preclinical settings. Computational statistical methods such as voxelwise analysis have shown promise in localizing and quantifying bTBI throughout the brain. In this study, we use voxelwise analysis of DTI to quantify white matter injury in a rat model of repetitive primary blast exposure. Our results show a significant increase in microstructural damage with a second blast exposure, suggesting that primary bTBI may sensitize the brain to subsequent injury.

The results obtained indicate that surface potential changes at the semiconductor/dielectric interface due to the presence of different work function metals can be detected from HAXPES measurements. Changes in the semiconductor band bending at zero gate voltage and the flat band voltage values derived from C-V measurements are in agreement with the semiconductor core level shifts measured from the HAXPES spectra. These results highlight the potential application of this measurement approach in the evaluation of the efficacy of surface passivation treatments: HAXPES hard x-ray photoelectron spectroscopy; C-V capacitance voltage; D-it-interface state density; BE binding energy, at reducing defect states densities in MOS structures.

Comparative whole genome analysis revealed high sequence homogeneity among these brucellaphage genomes and resolved three genetic groups consistent with defined host range phenotypes. Group I was composed of Tb and Fz phages that are predominantly lytic for Brucella abortus and Brucella neotomae; Group II included Bk, R/C, and Pr phages that are lytic mainly for B. abortus, Brucella melitensis and Brucella suis; Group III was composed of Wb and S708 phages that are lytic for B. suis, B. abortus and B. neotomae. We found that the putative phage collar protein is a variable locus with features that may be contributing to the host specificities exhibited by different brucellaphage groups. The presence of several candidate host range determinants is illustrated herein for future dissection of the differential host specificity observed among these phages. Published by Elsevier B.V.

However, LiCoPO4 has relatively poor electronic conductivity which may be improved by chemical substitution. In this work, the ionic and electronic conductivities of dense, polycrystalline LiCoPO4 and Fe2+/Fe3+-substituted LiCoPO4 (Li(1-)xCo(0.9)Fe(0.1)PO(4)) are measured and compared. Both materials are predominantly ionic conductors with relatively good bulk ionic and relatively poor electronic conductivities. Li(1-)xCo(0.9)Fe(0.1)PO(4) exhibits both higher bulk ionic and electronic conductivity. The increased bulk ionic conductivity of Li(1-)xCo(0.9)Fe(0.1)PO(4) is believed to originate mainly from extra Li vacancies and the increased electronic conductivity is believed to originate mainly from creating more mobile hole polarons compared to LiCoPO4 as a result of Fe2+/Fe3+ substitution.

In addition, a silica surface was tested as a representative hydrophilic substrate. The polymer-coated surfaces showed significantly lower fouling levels than uncoated controls. Because of the anti-polyelectrolyte nature of sulfobetaine zwitterionic polymers, the effect of salt concentration on the coating solutions and the quality of the polymer coating against fouling are studied. The coating method involves only water-based solutions, which is compatible with most surfaces and is environmentally friendly. To demonstrate the versatility of the reported method, we evaluated the fouling levels of the polymer coating on commonly used polymeric surfaces such as polypropylene (PP), polydirnethylsiloxane (PDMS), polystyrene (PS), nylon, polyvinyl chloride (PVC), and poly(methyl methacrylate) (PMMA).

A sample mounting technique on a curved surface is presented that ensures contact between an unmodified fiber and substrate. The indentation analysis considers three separate corrections to the well-known Oliver and Pharr method: (i) overestimation of the projected contact area due to sample curvature, (ii) overestimation of projected contact area due to substrate curvature, and (iii) underestimation of fiber stiffness due to the structural compliance of the sample. The method is applied to four types of high performance ballistic fibers: KM2 Plus, Twaron, AuTx, and Dyneema; the results are presented according to both the modified analyses as well as the standard Oliver and Pharr analysis. The modified analyses resulted in an increase in the elastic modulus and hardness of up to 35 and 60%, respectively, compared to the Oliver-Pharr method. The technique has the potential to be applied to single microfilaments under various environmental conditions that may otherwise be compromised by traditional fiber mounting methods.

Here, we present coarse-grained molecular dynamics simulations of the effects of solvent molecular weight on the toughness of entangled and non-entangled polymer gels in the ballistic impact regime. Our results demonstrate that higher molecular weight solvents enhance gel toughness, and that mechanical properties including strength and toughness can be influenced by bond scission. Further, we find a remarkable two-step gel fracture mechanism on the molecular level: network chains undergo scission first (and well before fracture), followed by scission of solvent chains. For strain rates greater than inverse relaxation time of the solvent, long, highly entangled solvent chains provide fracture resistance even after the network chains break by effectively increasing the number of chains that must be broken as a crack propagates.

TI Multi-Faceted Proteomic Characterization of Host Protein Complement of Rift Valley Fever Virus Virions and Identification of Specific Heat Shock Proteins, Including HSP90, as Important Viral Host Factors SO PLOS ONE LA English DT Article ID OXIDATIVELY DAMAGED PROTEINS; MASS-SPECTROMETRY ANALYSIS; TRANSPORT CHAIN COMPLEXES; RAPID DETECTION; CYCLOPHILIN-A; HIV-1 VIRIONS; LASSA VIRUS; CELLS; INFECTION; REPLICATION AB Rift Valley fever is a potentially fatal disease of humans and domestic animals caused by Rift Valley fever virus (RVFV). Infection with RVFV in ruminants can cause near 100% abortion rates and recent outbreaks in naive human populations have suggested case fatality rates of greater than thirty percent. To elucidate the roles that host proteins play during RVFV infection, proteomic analysis of RVFV virions was conducted using complementary analytical approaches, followed by functional validation studies of select identified host factors. Coupling the more traditional Gel LC/MS/MS approach (SDS PAGE followed by liquid chromatography tandem mass spectrometry) with an alternative technique that preserves protein complexes allowed the protein complement of these viral particles to be thoroughly examined. In addition to viral proteins present within the virions and virion-associated host proteins, multiple macromolecular complexes were identified. Bioinformatic analysis showed that host chaperones were among over-represented protein families associated with virions, and functional experiments using siRNA gene silencing and small molecule inhibitors identified several of these heat shock proteins, including heat shock protein 90 (HSP90), as important viral host factors. Further analysis indicated that HSP inhibition effects occur during the replication/transcription phase of the virus life cycle, leading to significant lowering of viral titers without compromising the functional capacity of released virions. Overall, these studies provide much needed further insight into interactions between RVFV and host cells, increasing our understanding of the infection process and suggesting novel strategies for anti-viral development. In particular, considering that several HSP90 inhibitors have been advancing through clinical trials for cancer treatment, these results also highlight the exciting potential of repurposing HSP90 inhibitors to treat RVF.

People with lower limb amputation experience considerable impairments in walking ability, including increased fall risk. Understanding the biomechanical aspects of the gait of these patients is crucial in improving their gait function and their quality of life. In the present study, 9 persons with unilateral transtibial amputation and 13 able-bodied controls walked on a large treadmill in a Computer Assisted Rehabilitation Environment (CAREN). While walking, subjects were either not perturbed, or were perturbed either by continuous mediolateral platform movements or by continuous mediolateral movements of the visual scene. Means and standard deviations of both step lengths and step widths increased significantly during both perturbation conditions (all p < 0.001) for both groups. Measures of variability, local and orbital dynamic stability of trunk movements likewise exhibited large and highly significant increases during both perturbation conditions (all p <0.001) for both groups. Patients with amputation exhibited greater step width variability (p = 0.01) and greater trunk movement variability (p = 0.04) during platform perturbations, but did not exhibit greater local or orbital instability than healthy controls for either perturbation conditions. Our findings suggest that, in the absence of other co-morbidities, patients with unilateral transtibial amputation appear to retain sufficient sensory and motor function to maintain overall upper body stability during walking, even when substantially challenged. Additionally, these patients did not appear to rely more heavily on visual feedback to maintain trunk stability during these walking tasks. (C) 2014 Elsevier Ltd. All rights reserved.

The measured room-temperature magnetization for the as-prepared magnetic nanoparticles (MNP) synthesized via polyol-reduction and coprecipitation is 69 Am-2 kg(-1) and 14 Am-2 kg(-1), respectively. X-ray diffraction measurements confirm spinel structure of the particles with an estimated grain size of similar to 80 nm obtained from the polyol-reduction and 28 nm obtained from these coprecipitation techniques. Upon calcination under atmospheric conditions at different temperatures between 800 degrees C and 1000 degrees C, the magnetization, M, of the coprecipitated MNP increases to 76 Am-2 kg(-1) with an estimated grain size of 90 nm. The MNP-polymer nanocomposites made from the synthesized MNP in various loading fraction and high density polyethylene exhibit interesting electromagnetic properties. The measured permeability and permittivity of the magnetic nanoparticle-polymer nanocomposites increases with the loading fractions of the magnetic nanoparticles, suggesting control for impedance matching for antenna applications.

TI Adjusting magnetic nanostructures for high-performance magnetic sensors SO JOURNAL OF APPLIED PHYSICS LA English DT Article; Proceedings Paper CT 58th Annual Conference on Magnetism and Magnetic Materials CY NOV 04-08, 2013 CL Denver, CO ID TUNNELING JUNCTIONS AB The magnetic properties of the soft ferromagnetic layer in magnetic tunnel junctions are one of key factors to determine the performance of magnetoresistance sensors. We use a three-step orthogonal annealing procedure to modify the nanostructures of the free layer in the magnetic tunnel junction to control features such as magnetization reversal, coercivity, exchange field, and tunnel magnetoresistance ratio. We present a sensor with an improved sensitivity as high as 3944%/mT. This magnetic sensor only dissipates 200 mu W of power while operating under an applied voltage of 1 V.

TI Discrepant Amplification Results during the Development of an Assay Leads to Reclassification of Two AIDS Reagent Repository HIV-2 Isolates as HIV-1 SO PLOS ONE LA English DT Article ID IMMUNODEFICIENCY-VIRUS TYPE-2; VIRAL LOAD ASSAY; CLINICAL-USE; INFECTION; QUANTIFICATION; VALIDATION AB The development and verification of HIV-2 assays depends in part on the availability of well-characterized samples, including those from reagent repositories. During the development of an HIV-2 RNA quantification assay, two HIV-2 viral isolates (CDC 301340 and CDC 301342) obtained from the NIAID AIDS Reagent and Reference Repository were not detected leading to an investigation. Two HIV-2 primers/probe sets of known performance in real-time viral RNA quantification assays, targeting different regions of the virus, also failed to generate RT-PCR products for these two isolates. These isolates were tested in the HIV-1 specific COBAS AmpliPrep/COBAS TaqMan HIV-1 Test v2.0 (Roche Molecular Diagnostics) and were quantified at high copy number. Other HIV-2 isolates tested were not amplified in the COBAS HIV-1 TaqMan assay. Furthermore, the discrepant isolates were highly reactive in an HIV-1 p24 antigen test while the other HIV-2 isolates showed very weak, if any, cross-reactivity with the HIV-1 p24 assay. Phylogenetic tree analysis of sequences from the protease-reverse transcriptase regions of the discrepant HIV-2 isolates mapped with HIV-1 Group M, Subtype CRF02_AG confirming these isolates were of HIV-1 origin and had been misclassified as HIV-2. The use of misclassified isolates in the verification of molecular and immunological assays can lead to misinterpretation of test results, misdirection of efforts into assay redesign and increased development costs. The results of this study were shared with the NIAID AIDS Reagent Program, leading to the reclassification of the two discrepant isolates as HIV-1.

TI Design of dual-link (wide- and narrow-beam) LED communication systems SO OPTICS EXPRESS LA English DT Article ID WIRELESS NETWORKS; RF; LIGHT AB We explore the design of an LED-based communication system comprising two free space optical links: one narrow-beam (primary) link for bulk data transmission and one wide-beam (beacon) link for alignment and support of the narrow-beam link. Such a system combines the high throughput of a highly directional link with the robust insensitivity to pointing errors of a wider-beam link. We develop a modeling framework for this dual-link configuration and then use this framework to explore system tradeoffs in power, range, and achievable rates. The proposed design presents a low-cost, compact, robust means of communication at short-to medium-ranges, and calculations show that data rates on the order of Mb/s are achievable at hundreds of meters with only a few LEDs.

We demonstrate that placing the GaAsSb QW beneath the QDs forms type-II characteristics that initiate at 12% Sb composition. Current density-voltage measurements demonstrate a decrease in power efficiency with increasing Sb composition. This could be attributed to increased valence band potential in the GaAsSb QW that subsequently limits hole transportation in the QD region. To reduce the confinement energy barrier, a 2 nm GaAs wall is inserted between GaAsSb QW and InAs QDs, leading to a 23% improvement in power efficiency for QDSCs.

TI Effects of Respirator Ambient Air Cooling on Thermophysiological Responses and Comfort Sensations SO JOURNAL OF OCCUPATIONAL AND ENVIRONMENTAL HYGIENE LA English DT Article DE full-facepiece respirator; ambient cooling; comfort; thermal sensation ID PROTECTIVE DEVICES; EXERCISE PERFORMANCE; RATING-SCALE; INTERMITTENT; HYPERTHERMIA; WORK; HUMANS; REST; PAIN AB This investigation assessed the thermophysiological and subjective impacts of different respirator ambient air cooling options while wearing chemical and biological personal protective equipment in a warm environment (32.7 +/- 0.4 degrees C, 49.6 +/- 6.5% RH). Ten volunteers participated in 90-min heat exposure trials with and without respirator (Control) wear and performed computer-generated tasks while seated. Ambient air cooling was provided to respirators modified to blow air to the forehead (FHC) or to the forehead and the breathing zone (BZC) of a full-facepiece air-purifying respirator using a low-flow (45 Lmin(-1)) mini-blower. An unmodified respirator (APR) trial was also completed. The highest body temperatures (T-TY) and least favorable comfort ratings were observed for the APR condition. With ambient cooling over the last 60min of heat exposure, T-TY averaged 37.4 +/- 0.6 degrees C for Control, 38.0 +/- 0.4 degrees C for APR, 37.8 +/- 0.5 degrees C for FHC, and 37.6 +/- 0.7 degrees C for BZC conditions independent of time. Both the FHC and BZC ambient air cooling conditions reduced facial skin temperatures, reduced the rise in body temperatures, and led to more favorable subjective comfort and thermal sensation ratings over time compared to the APR condition; however statistical differences among conditions were inconsistent. Independent of exposure time, average breathing apparatus comfort scores with BZC (7.2 +/- 2.5) were significantly different from both Control (8.9 +/- 1.4) and APR (6.5 +/- 2.2) conditions when ambient cooling was activated. These findings suggest that low-flow ambient air cooling of the face under low work rate conditions and mild hyperthermia may be a practical method to minimize the thermophysiological strain and reduce perceived respirator discomfort.

To understand its folding mechanism, we performed urea denaturation experiments and theoretical modeling using BoNT serotype A (BoNT/A). We found that the extent of BoNT/A denaturation from the native state (N) shows a nonmonotonic dependence on urea concentration indicating a unique multistep denaturation process, N -> I-1 I-2 U, with two intermediate states I-1 and I-2. BoNT/A loses almost all its secondary structure in 3.75 M urea (I-1), yet it displays a native-like secondary structure in 5 M urea (I-2). This agrees with the results of theoretical modeling, which helped to determine the molecular basis of unique behavior of BoNT/A in solution. Except for I-2, all the states revert back to full enzymatic activity for SNAP-25 including the unfolded state U stable in 7 M urea. Our results stress the importance of structural flexibility in the toxin's mechanism of survival and action, an unmatched evolutionary trait from billion-year-old bacteria, which also correlates with the long-lasting enzymatic activity of BoNT inside neuronal cells. BoNT/A provides a rich model to explore protein folding in relation to functional activity.

TI Potential Partners in the Pacific? Mutual interests and the Sino-NATO relationship SO JOURNAL OF CONTEMPORARY CHINA LA English DT Article AB Is there mutual benefit in a relationship between the People's Republic of China and the North Atlantic Treaty Alliance (NATO)? At first glance, China and NATO appear to have little to offer one another, and many obstacles to cooperation exist. But distinct (and different) benefits exist for both parties should they elect to pursue a relationship based on interests. NATO and China share a common interest in maintaining international security, and increased interaction can thus appeal to NATO's desire to extend cooperative security beyond the Euro-Atlantic area while offering the Chinese a means for protecting their interests on the global stage in a constructive, non-threatening manner. While both NATO and China have interests in Afghanistan, the most fertile ground for a future relationship lies in mutual interests in four 'politically acceptable' domains: crisis management, humanitarian assistance/disaster relief, counter-proliferation and counter-piracy. Increased interaction will present both NATO and China with risks, but these are ultimately outweighed by the potential benefits.

TI A systematic review and meta-analysis on the prevalence of dietary supplement use by military personnel SO BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE LA English DT Article DE Vitamins; Minerals; Multivitamins; Vitamin C; Vitamin E; Calcium; Iron; Protein; Creatine; Sport drink ID HEALTH INTERVIEW SURVEY; UNITED-STATES; ENERGY DRINKS; NATIONAL-HEALTH; CREATINE SUPPLEMENTATION; CARDIOVASCULAR-DISEASE; MINERAL SUPPLEMENTS; ARMY SOLDIERS; MULTIMINERAL SUPPLEMENTATION; NUTRITIONAL SUPPLEMENTS AB Background: Although a number of studies have been conducted on the prevalence of dietary supplement (DS) use in military personnel, these investigations have not been previously summarized. This article provides a systematic literature review of this topic. Methods: Literature databases, reference lists, and other sources were searched to find studies that quantitatively examined the prevalence of DS use in uniformed military groups. Prevalence data were summarized by gender and military service. Where there were at least two investigations, meta-analysis was performed using a random model and homogeneity of the prevalence values was assessed. Results: The prevalence of any DS use for Army, Navy, Air Force, and Marine Corps men was 55%, 60%, 60%, and 61%, respectively; for women corresponding values were 65%, 71%, 76%, and 71%, respectively. Prevalence of multivitamin and/or multimineral (MVM) use for Army, Navy, Air Force, and Marine Corps men was 32%, 46%, 47%, and 41%, respectively; for women corresponding values were 40%, 55%, 63%, and 53%, respectively. Use prevalence of any individual vitamin or mineral supplement for Army, Navy, Air Force, and Marine Corps men was 18%, 27%, 25%, and 24%, respectively; for women corresponding values were 29%, 36%, 40%, and 33%, respectively. Men in elite military groups (Navy Special Operations, Army Rangers, and Army Special Forces) had a use prevalence of 76% for any DS and 37% for MVM, although individual studies were not homogenous. Among Army men, Army women, and elite military men, use prevalence of Vitamin C was 15% for all three groups; for Vitamin E, use prevalence was 8%, 7%, and 9%, respectively; for sport drinks, use prevalence was 22%, 25% and 39%, respectively. Use prevalence of herbal supplements was generally low compared to vitamins, minerals, and sport drinks, <= 5% in most investigations. Conclusions: Compared to men, military women had a higher use prevalence of any DS and MVM. Army men and women tended to use DSs and MVM less than other service members. Elite military men appeared to use DSs and sport drinks more than other service members.

TI Diffusion Tensor Imaging Reveals Acute Subcortical Changes after Mild Blast-Induced Traumatic Brain Injury SO SCIENTIFIC REPORTS LA English DT Article ID LONG-TERM CONSEQUENCES; AXONAL INJURY; MILITARY; CONCUSSION; BIOMARKERS; VETERANS; COMBAT; MODEL; RATS; MRI AB Mild blast-induced traumatic brain injury (mbTBI) poses special diagnostic challenges due to its overlapping symptomatology with other neuropsychiatric conditions and the lack of objective outcome measures. Diffusion tensor imaging (DTI) can potentially provide clinically relevant information toward a differential diagnosis. In this study, we aimed to determine if single and repeated (5 total; administered on consecutive days) mild blast overpressure exposure results in detectable structural changes in the brain, especially in the hippocampus. Fixed rat brains were analyzed by ex vivo DTI at 2 h and 42 days after blast (or sham) exposure(s). An anatomy-based region of interest analysis revealed significant interactions in axial and radial diffusivity in a number of subcortical structures at 2 h only. Differences between single-and multiple-injured rats were largely in the thalamus but not the hippocampus. Our findings demonstrate the value and the limitations of DTI in providing a better understanding of mbTBI pathobiology.

TI Prevalence of Supranormal Pulmonary Function Test Values Between a Military and Nonmilitary Cohort SO RESPIRATORY CARE LA English DT Article DE pulmonary junction testing; military personnel; supranormal values ID LUNG-FUNCTION; RESPIRATORY MUSCLE; EXERCISE; SWIMMERS; PERFORMANCE; ASTHMA AB BACKGROUND: The study objective was to determine differences in the proportion of supranormal pulmonary function tests (PFTs) between active duty (AD) military personnel and a similar non-active duty (non-AD) population. Given the emphasis on cardiovascular fitness in the military, it has been hypothesized that regular exercise in this cohort leads to an increased proportion of supranormal PFTs. We hypothesized that a comparison of PFTs would identify no differences in the ratio of supranormal to normal PFTs between the AD and non-AD populations. METHODS: A retrospective chart review was conducted of all PFT studies at the Brooke Army Medical Center from 2006 to 2011. Studies were included with either an FVC or FEV1 > 110% of predicted, with both values > 100% of predicted. A comparative analysis was performed for patients between 18 and 50 years of age based on AD status. Further analysis was performed on all ages to determine the distribution of supranormal findings in the entire study population. RESULTS: A total of 16,600 interpreted PFTs were queried. Of those, 4.303 (31.6%) were AD patients, and 9,306 (68.4%) were non-AD patients. From all of the PFTs reviewed, a total of 912 (6.7%) were identified as supranormal. When further analyzed, 381 (9.4%) of AD patients 18-50 years old were supranormal, 175 (12.4%) of non-AD patients 18-50 years old were supranormal, and 356 (4.7%) of non-AD patients older than 50 years were supranormal. CONCLUSIONS: This study revealed no significant difference in the proportion of supranormal-to-normal PFTs in an AD versus non-AD duty population of the same age range. Based on these findings, no assumption should be made that supranormal PFTs are more common in military personnel. Interpretation of normal PFTs in AD personnel undergoing evaluation should not differ from that in any typical patient.

TI Investigating the Consistency of Asphalt Density Measurement Methods Over a Wide Range of Air Voids SO JOURNAL OF TESTING AND EVALUATION LA English DT Article DE Asphalt Mixture; Flexible Pavements; Bulk Density; Bulk Specific Gravity; Air Voids ID BULK SPECIFIC-GRAVITY; CONCRETE; MIXTURES AB The overall purpose of this paper is to identify the most reliable bulk mixture specific gravity (G(mb)) measurement method for dense graded asphalt concrete that can be used for a wide range of air voids and specimen types. A secondary purpose is to identify ranges of conditions where less established G(mb) measurement methods are suitable. A comprehensive literature review was performed to identify promising density test methods for further study. Findings from studies comparing AASHTO T166 (saturated surface dry method) and AASHTO T331 (Corelok method) were used to provide a succinct summary of the relative behaviors of the two methods at mix design, performance testing, and field construction air void levels. Density measurement was performed using four methods (AASHTO T166, T269, T331, and TP82) on dense graded mixture specimens. In total, approximately 2500 data points were used herein, with approximately 30 % of this total coming from literature review and 70 % coming from the authors of this paper. Review of literature along with the evidence presented in this paper indicates that T331 is the most reasonably accurate and versatile G(mb) measurement method for a wide range of air voids all the way from mix design through performance testing to construction acceptance testing. T331 has also been recommended (or at least evaluated favorably) by several previous researchers over the last ten years. Based on the evidence presented in this paper, the provisional TP82 test method in its current form does not provide acceptable G(mb) measurements relative to T166 or T331 over a wide range of air voids. The magnitude of the discrepancy begins to increase dramatically as air voids increase.

TI A New Test for Cementation Potential of Embankment Dam Granular Filter Material SO GEOTECHNICAL TESTING JOURNAL LA English DT Article DE embankment dam; granular filter material; cohesion; cementation; cracking; modified sand castle test; internal erosion ID SOILS AB Granular filters are used in embankment dams to protect against uncontrolled flow and internal erosion either through the embankment or the foundation. For proper performance, the filter material must not be able to sustain a crack even if the core material becomes cracked itself. Historically, the mechanism used to limit cracking potential is a restriction of no more than 5 % nonplastic fines. It has been recognized though that this requirement has not been effective in identifying cracking potential for all materials. Since the requirement is related to the exclusion of clay and silt size particles (i.e., fines) it appears to not always identify other minerals that can act as cementing agents. A supplemental test known as the Sand Castle Test was also developed, and although it did not specifically focus on detecting other binding agents it was thought to hold promise. However, since the original test lacked a precise procedure and sensitivity to some binding agents, a modification of the Sand Castle Test is being undertaken. This paper outlines the need for a new test and describes specimen preparation, Modified Sand Castle Test procedures, and results from 16 source materials from across the United States. A petrographic examination was carried out to investigate the cementing mechanisms in selected materials. Additionally, unconfined compression tests were performed on each material to help quantify the strength from cementation. The sand equivalency value was also determined for all materials to see how well it correlated with the Modified Sand Castle Test results. The Modified Sand Castle Test is shown to be a good indicator of cementation potential and correlates well with unconfined compressive strength, but to a lesser degree with sand equivalency value.

Over the past decade, attrition rates in the Army have averaged between 25% and 30% during first-term periods of enlistment. Historically, the services have relied on education credentials, with special emphasis on possessing a high school diploma, as a primary indicator of completion rates after enlistment and as a proxy for the ability to adapt to a military lifestyle. A primary purpose of this paper is to describe Army research to develop new indicators of adaptability to augment the current system based on education credentials. This work has focused primarily on noncognitive, personality measures and how such measures can be combined with other existing measures for attrition screening during enlistment processing. These advances represent a new paradigm that relies less heavily on education credentials and can provide a more comprehensive and inclusive approach. This new approach incorporates advances in testing methodology to make it more viable for use in large-scale, high-stakes testing applications.

TI A Retrospective Cohort Study of Military Deployment and Postdeployment Medical Encounters for Respiratory Conditions SO MILITARY MEDICINE LA English DT Article ID PARTICULATE MATTER; LUNG-DISEASE; HEALTH; AFGHANISTAN; PERSONNEL; SYMPTOMS; IRAQ; EXPOSURE; SOLDIERS; BIAS AB Deployed military personnel are exposed to inhalational hazards that may increase their risk of chronic lung conditions. This evaluation assessed associations between Operation Iraqi Freedom (OIF) deployment and post-deployment medical encounters for respiratory symptoms and medical conditions. This retrospective cohort study was conducted among military personnel who, between January 2005 and June 2007, were deployed to either of two locations with burn pits in Iraq, or to either of two locations without burn pits in Kuwait. Incidence rate ratios (IRRs) were estimated using two nondeployed reference groups. Rates among personnel deployed to burn pit locations were also compared directly to those among personnel deployed to locations without burn pits. Significantly elevated rates of encounters for respiratory symptoms (IRR = 1.25; 95% confidence interval [CI]: 1.20-1.30) and asthma (IRR = 1.54; 95% CI: 1.33-1.78) were observed among the formerly deployed personnel relative to U.S.-stationed personnel. Personnel deployed to burn pit locations did not have significantly elevated rates for any of the outcomes relative to personnel deployed to locations without burn pits. These results are consistent with the hypothesis that OIF deployment is associated with subsequent risk of respiratory conditions. Elevated medical encounter rates were not uniquely associated with burn pits.

This investigation examined PTRP admission incidence among recruits in IET at Forts Jackson, Leonard Wood, Benning, and Sill during Fiscal Year 2011 (FY11). PTRP admission data were collected from a spreadsheet completed monthly by PTRP commanders. Total number of recruits was obtained from each post's Directorate of Programs, Training, and Management. In FY11, 368 men and 268 women were admitted into PTRPs at all installations. For Forts Jackson, Leonard Wood, Benning, and Sill, male admission incidences (cases/1,000 recruits) were 2.6, 3.0, 6.2, and 5.4, respectively; female admission incidences for Forts Jackson, Leonard Wood, and Sill, were 11.1, 10.1, and 22.6, respectively. Most injuries sent to PTRP were bone stress injuries (65%) or fractures (21%). 76% of recruits were returned to duty. Differences in admission incidence between posts appear primarily related to different local policies regarding convalescent leave and admission criteria. PTRP admission rates are lower than in the past, presumably related to policy changes and injury-reduction efforts. A cost-benefit analysis would assist in determining the value of the PTRP.

Although military nursing services recently have been able to meet their nursing recruitment quotas, national studies have predicted a long-term nursing shortage that may affect future recruitment for the Nurse Corps of the three military services. Data are needed to plan for recruitment incentives and the impact of those incentives on targeted populations of likely future nurses. Methods: Data are drawn from three online surveys conducted in 2011-2012, including surveys of 1,302 Army, Navy, and Air Force personnel serving on major military bases, 914 nursing students at colleges with entry Bachelor of Science in Nursing programs located nearby major military bases, and a qualitative survey of 1,200 young adults, age 18-39, in the general public. Findings: The three populations are different in several demographic characteristics. We explored perceptions of military careers, nursing careers and barriers, and incentives to pursue military nursing careers in all populations. Perceptions differ among the groups. Conclusion: The results of this study may help to inform strategies for reaching out to specific populations with targeted messages that focus on barriers and facilitators relevant to each to successfully recruit a diverse Nurse Corps for the future.

TI TSALLIS ENTROPY-BASED FLOW DURATION CURVE SO TRANSACTIONS OF THE ASABE LA English DT Article DE Duration curve; Entropy; Flow duration curve; Lagrange multipliers; Principle of maximum entropy; Tsallis entropy ID VELOCITY DISTRIBUTION; OPEN CHANNELS AB The flow duration curve (FDC) is employed for addressing a multitude of problems in water resources engineering, such as prediction of the distribution of future flows, forecasting of future recurrence frequencies, comparison of watersheds, construction of load duration curves, and determination of low flow thresholds. Usually, the FDC is constructed empirically for a given set of flow data, and the FDC so constructed is found to vary from one year to another and from one gauging station to another within the same watershed This article attempts to analytically derive the FDC by maximizing the Tsallis entropy based on the knowledge that the mean discharge is known, thus obviating the need for any fitting. The mean discharge is found to be strongly related to the drainage area. The Tsallis entropy-based FDC is tested using field data and is found to be in agreement with the observed curve. The entropy method permits a probabilistic characterization of the FDC and hence a quantitative assessment of its uncertainty. With this method, the flow duration curve can also be forecasted for different recurrence intervals. The entropy is found to monotonically increase with the increase in time interval, indicating that the flow system becomes more complex but the degree of complexity decreases with increasing time interval after a certain time, eventually reaching a constant value, reflecting a reduced influence of land use change and other human influences on the flow regime.

TI DETECTION OF NON-O157 SHIGA TOXIN-PRODUCING ESCHERICHIA COLI (STEC) SEROGROUPS WITH HYPERSPECTRAL MICROSCOPE IMAGING TECHNOLOGY SO TRANSACTIONS OF THE ASABE LA English DT Article DE Acousto-optic tunable filter; Bacteria; Dark-field illumination; Escherichia coli; Foodborne pathogen; Hyperspectral; Microscopy; STEC ID OUTBREAKS; SAFETY; SYSTEM; SKIN AB Non-O157 Shiga toxin-producing Escherichia coli (STEC) serogroups such as 026, 045, 0103, 0111, 0121, and 0145 are recognized as serious risks to human health due to their toxicity. The conventional microbiological detection method of cell counting on agar plates is laborious and time-consuming. Because optical methods are promising for real-time, in situ foodborne pathogen detection, a hyperspectral microscope imaging (HMI) method based on acousto-optic tunable filters (AOTF) was developed for detecting pathogenic bacteria with a capability to differentiate the spectral characteristics of each bacterial cell from microcolony samples. Using the AOTF-based HMI method, a total of 89 contiguous spectral images were acquired within approximately 45 s with 250 ms exposure time. In this study, we developed a protocol for successfully immobilizing live cells on glass slides to acquire quality spectral images of STEC bacterial cells using a modified drying method. Among the contiguous spectral imagery between 450 and 800 nm, the intensities at 458, 498, 522, 546, 570, 586, 670, and 690 nm were distinct for STEC bacteria under dark-field illumination. With two different classification algorithms, i.e., support vector machine (SVM) and sparse kernel-based ensemble learning (SKEL), STEC serogroup 045 could be classified with 92% detection accuracy. However, the mean accuracies in identifying the six STEC serogroups with SVM and SKEL were not high enough for use in classification models. C1 [Park, B.; Windham, W. R.; Yoon, S. C.; Lawrence, K.

TI AB5075, a Highly Virulent Isolate of Acinetobacter baumannii, as a Model Strain for the Evaluation of Pathogenesis and Antimicrobial Treatments SO MBIO LA English DT Article ID GALLERIA-MELLONELLA; SYSTEM; OSTEOMYELITIS; RESISTANCE; INFECTION; IDENTIFICATION; VALIDATION; MILITARY; COLISTIN; CLONING AB Acinetobacter baumannii is recognized as an emerging bacterial pathogen because of traits such as prolonged survival in a desiccated state, effective nosocomial transmission, and an inherent ability to acquire antibiotic resistance genes. A pressing need in the field of A. baumannii research is a suitable model strain that is representative of current clinical isolates, is highly virulent in established animal models, and can be genetically manipulated. To identify a suitable strain, a genetically diverse set of recent U. S. military clinical isolates was assessed. Pulsed-field gel electrophoresis and multiplex PCR determined the genetic diversity of 33 A. baumannii isolates. Subsequently, five representative isolates were tested in murine pulmonary and Galleria mellonella models of infection. Infections with one strain, AB5075, were considerably more severe in both animal models than those with other isolates, as there was a significant decrease in survival rates. AB5075 also caused osteomyelitis in a rat open fracture model, while another isolate did not. Additionally, a Tn5 transposon library was successfully generated in AB5075, and the insertion of exogenous genes into the AB5075 chromosome via Tn7 was completed, suggesting that this isolate may be genetically amenable for research purposes. Finally, proof-of-concept experiments with the antibiotic rifampin showed that this strain can be used in animal models to assess therapies under numerous parameters, including survival rates and lung bacterial burden. We propose that AB5075 can serve as a model strain for A. baumannii pathogenesis due to its relatively recent isolation, multidrug resistance, reproducible virulence in animal models, and genetic tractability. IMPORTANCE The incidence of A. baumannii infections has increased over the last decade, and unfortunately, so has antibiotic resistance in this bacterial species. A. baumannii is now responsible for more than 10% of all hospital-acquired infections in the United States and has a > 50% mortality rate in patients with sepsis and pneumonia. Most research on the pathogenicity of A. baumannii focused on isolates that are not truly representative of current multidrug-resistant strains isolated from patients. After screening of a panel of isolates in different in vitro and in vivo assays, the strain AB5075 was selected as more suitable for research because of its antibiotic resistance profile and increased virulence in animal models. Moreover, AB5075 is susceptible to tetracycline and hygromycin, which makes it amenable to genetic manipulation. Taken together, these traits make AB5075 a good candidate for use in studying virulence and pathogenicity of this species and testing novel antimicrobials.

However, there are currently no common standards used to convey the quality, and therefore utility, of these various genome sequences. Here, we propose five "standard" categories that encompass all stages of viral genome finishing, and we define them using simple criteria that are agnostic to the technology used for sequencing. We also provide genome finishing recommendations for various downstream applications, keeping in mind the cost-benefit trade-offs associated with different levels of finishing. Our goal is to define a common vocabulary that will allow comparison of genome quality across different research groups, sequencing platforms, and assembly techniques.

The neurotoxins responsible for PSP, collectively referred to as the saxitoxins or paralytic shellfish toxins (PSTs), are natural toxins, produced by certain dinoflagellates, that may accumulate in seafood, particularly filter-feeding bivalves. Illnesses are rare because of effective monitoring programs, yet occasional poisonings occur. Rarely are contaminated food and human clinical samples (e.g., urine and serum) available for testing. There are currently few methods, none of which are validated, for determining PSTs in clinical matrices. This study evaluated AOAC (Association of Analytical Communities) Official Method of Analysis (OMA) 2005.06. [AOAC Official Method 2005.06 Paralytic Shellfish Poisoning Toxins in Shellfish: Prechormatographic Oxidation and Liquid Chromatography with Fluorescence Detection. In Official Methods of Analysis of AOAC International < http://www.eoma.aoac.org >],validatedonlyfor shellfish extracts, for its extension to human urine and serum samples. Initial assessment of control urine and serum matrices resulted in a sample cleanup modification when working with urine to remove hippuric acid, a natural urinary compound of environmental/dietary origin, which co-eluted with saxitoxin. Commercially available urine and serum matrices were then quantitatively spiked with PSTs that were available as certified reference materials (STX, dcSTX, BI, GTX2/3, C1/2, NEO, and GTX1/4) to assess method performance characteristics. The method was subsequently applied successfully to a PSP case study that occurred in July 2007 in Maine. Not only were PSTs identified in the patient urine and serum samples, the measured time series also led to the first report of human PST-specific urinary elimination rates. The LC-FD data generated from this case study compared remarkably well to results obtained using AOAC OMA 2011.27 [AOAC Official Method 2011.27 Paralytic Shellfish Toxins (PSTs) in Shellfish, Receptor Binding Assay. In Official Methods of Analysis of AOAC International < http://www.eoma.aoac.org >], further demonstrating successful extension of the LC-FD method to these clinical matrices. Moreover, data generated from this poisoning event reiterated that urine is a preferable clinical matrix, compared to serum, for diagnostic purposes due to higher accumulation and longer residence times in urine.

By contrasting the responses to cyanide (CN) poisoning versus hemorrhage in animal models, we demonstrate that diffuse optical spectroscopy (DOS) can detect cytochrome c oxidase (CcO) redox states. Intermittent decreases in inspired O-2 from 100% to 21% were applied before, during, and after CN poisoning, hemorrhage, and resuscitation in rabbits. Continuous DOS measurements of total hemoglobin, oxyhemoglobin, deoxyhemoglobin, and oxidized and reduced CcO from muscle were obtained. Rabbit hemorrhage was accomplished with stepwise removal of blood, followed by blood resuscitation. CN treated rabbits received 0.166 mg/min NaCN infusion. During hemorrhage, CcO redox state became reduced concurrently with decreases in oxyhemoglobin, resulting from reduced tissue oxygen delivery and hypoxia. In contrast, during CN infusion, CcO redox state decreased while oxyhemoglobin concentration increased due to CN binding and reduction of CcO with resultant inhibition of the electron transport chain. Spectral absorption similarities between hemoglobin and CcO make noninvasive spectroscopic distinction of CcO redox states difficult. By contrasting physiological perturbations of CN poisoning versus hemorrhage, we demonstrate that DOS measured CcO redox state changes are decoupled from hemoglobin concentration measurement changes.

Machine-learned Bayesian Belief Networks (ml-BBNs) accurately estimate outcomes in CC, providing clinicians with Clinical Decision Support System (CDSS) tools to facilitate treatment planning. We evaluated ml-BBNs ability to estimate survival and recurrence in CC. We performed a retrospective analysis of registry data of patients with CC to train-test-crossvalidate ml-BBNs using the Department of Defense Automated Central Tumor Registry (January 1993 to December 2004). Cases with events or follow-up that passed quality control were stratified into 1-, 2-, 3-, and 5-year survival cohorts. ml-BBNs were trained using machine-learning algorithms and k-fold crossvalidation and receiver operating characteristic curve analysis used for validation. BBNs were comprised of 5301 patients and areas under the curve ranged from 0.85 to 0.90. Positive predictive values for recurrence and mortality ranged from 78 to 84 per cent and negative predictive values from 74 to 90 per cent by survival cohort. In the 12-month model alone, 1,132,462,080 unique rule sets allow physicians to predict individual recurrence/mortality estimates. Patients with Stage II (N0M0) CC benefit from chemotherapy at different rates. At one year, all patients older than 73 years of age with T2-4 tumors and abnormal carcinoembryonic antigen levels benefited, whereas at five years, all had relative reduction in mortality with the largest benefit amongst elderly, highest T-stage patients. ml-BBN can readily predict which high-risk patients benefit from adjuvant therapy. CDSS tools yield individualized, clinically relevant estimates of outcomes to assist clinicians in treatment planning.

TI Modular Extracorporeal Life Support: Effects of Ultrafiltrate Recirculation on the Performance of an Extracorporeal Carbon Dioxide Removal Device SO ASAIO JOURNAL LA English DT Article DE extracorporeal carbon dioxide removal; hemofiltration; recirculation; respiratory dialysis ID ACUTE LUNG INJURY; POSITIVE-PRESSURE VENTILATION; RESPIRATORY-DISTRESS-SYNDROME; CO2 REMOVAL; MECHANICAL VENTILATION; MEMBRANE-OXYGENATION; 6 ML/KG; COAGULATION; EXPERIENCE; MORTALITY AB The combination of extracorporeal carbon dioxide removal (ECCO2R) and hemofiltration is a possible therapeutic strategy for patients needing both lung and renal support. We tested the effects of the recirculation of ultrafiltrate on membrane lung (ML) CO2 removal (VCO2ML). Three conscious, spontaneously breathing sheep were connected to a commercially produced ECCO2R device (Hemolung; Alung Technologies, Pittsburgh, PA) with a blood flow of 250 ml/min and a gas flow of 10 L/min. A hemofilter (NxStage, NxStage Medical, Lawrence, MA) was interposed in series after the ML. Ultrafiltrate flow was generated and recirculated before the ML. We tested four ultrafiltrate flows (0, 50, 100, and 150 ml/min) for 25 min each, eight times per animal, resulting in 24 randomized test repetitions. We recorded VCO2ML, hemodynamics and ventilatory variables, and natural lung CO2 transfer (VCO2NL) and collected arterial and circuitry blood samples. VCO2ML was unchanged by application of ultrafiltrate recirculation (40.5 +/- 4.0, 39.7 +/- 4.2, 39.8 +/- 4.2, and 39.2 +/- 4.1 ml/min, respectively, at ultrafiltrate flow of 0, 50, 100, and 150 ml/min). Minute ventilation, respiratory rate, VCO2NL, and arterial blood analyses were not affected by ultrafiltrate recirculation. In the tested configuration, ultrafiltrate recirculation did not affect VCO2ML. This modular technology may provide a suitable platform for coupling CO2 removal with various forms of blood purification.

We tested sera from individuals immunized with adenovirus type 4 and 7 (Ad4 and Ad7, respectively) vaccine or naturally infected with Ad4 for their ability to neutralize a panel of E1-deleted human and chimpanzee adenoviruses (ChAd). Small statistically significant increases in titers to ChAd63, ChAd3, human Ad35, and human Ad5 were observed. Neutralizing antibodies elicited by Ad4 infection or immunization results in a small amount of adenovirus cross-reactivity.

Substantial evidence now exists showing how, and under what conditions, ecosystems can play a valuable function in wave and storm surge attenuation, erosion reduction, and in the longer term maintenance of the coastal profile. Both through their capacity for self repair and recovery, and through the often considerable cobenefits they provide, ecosystems can offer notable advantages over traditional engineering approaches in some settings. They can also be combined in hybrid engineering designs. We make 10 recommendations to encourage the utilization of existing knowledge and to improve the incorporation of ecosystems into policy, planning and funding for coastal hazard risk reduction.

The purpose of this article is to critically analyze the evidence on maternal and neonatal outcomes of waterbirth to help inform evidence-based clinical practice in the United States. Methods A literature search was performed using electronic databases CINAHL, Ovid MEDLINE, PubMed, EMBASE, and PsycINFO. Thirty-eight studies, including 2 randomized controlled trials and 36 observational studies, were reviewed. Studies were conducted in 11 countries, mostly outside the United States. More than 31,000 waterbirths were described. Results Aggregate results suggest that waterbirth is associated with high levels of maternal satisfaction with pain relief and the experience of childbirth, and may increase the likelihood of an intact perineum. Waterbirth is associated with decreased incidence of episiotomy and severe perineal lacerations, and may contribute to reduced postpartum hemorrhage. Data indicate no difference in maternal or neonatal infection rates or nursery admissions after waterbirth. Neonatal mortality rates are low and similar after waterbirth and uncomplicated conventional birth. The calculated cord avulsion rate is 2.4 per 1000 waterbirths; it is unknown how this compares to conventional birth due to a lack of data that permits direct comparison. Discussion The majority of waterbirth research to date is observational and descriptive; thus, reported outcomes do not demonstrate causal associations. However, existing evidence is reassuring. Case-controlled studies have included thousands of women who gave birth underwater without an apparent increase in maternal or neonatal morbidity or mortality. Potential risks associated with waterbirth for women and neonates appear minimal, and outcomes are comparable to those expected in any healthy childbearing population.

The exact tests reported in the literature assume that data samples for each variable are sequentially independent and identically distributed (iid). In general, time series data have dependencies (Markov structure) that violate this condition. The algorithm given in this paper is the first exact significance test of mutual information that takes into account the Markov structure. When the Markov order is not known or indefinite, an exact test is used to determine an effective Markov order. C1 [Pethel, Shawn D.] US Army RDECOM, RDMR WDS WO, Redstone Arsenal, AL 35898 USA.

To ascertain which elements of the immune system respond to infection, we explored transcriptional responses following infection of fathead minnow cells with either wild type (wt) FV3 or a knock out (KO) mutant targeting the 18 kDa immediate early gene (18K). At 8 h post infection we observed marked upregulation of multiple transcripts encoding proteins affecting innate and acquired immunity. Sequences expressed 4-fold or higher in wt-infected cells included transcripts encoding interferon (IFN), IFN regulatory factors (IRFs), IFN stimulated genes (ISGs) such as Mx and MHC class I, and interleukins IL-1 beta, IL-8, IL-17C and IL-12. Cells infected with the 18K KO mutant (Delta 18K) showed qualitative differences and lower levels of induction. Collectively, these results indicate that ranavirus infection induced expression of multiple cellular genes affecting both innate and acquired immunity. (C) 2014 Elsevier Inc. All rights reserved.

TI Temporal alterations in aquaporin and transcription factor HIF1 alpha et expression following penetrating ballistic-like brain injury (PBBI) SO MOLECULAR AND CELLULAR NEUROSCIENCE LA English DT Article DE Penetrating brain injury; PBBI; Edema; Aquaporins ID EDEMA FORMATION; WATER CHANNELS; RAT-BRAIN; BLOOD; MODEL; MECHANISMS; HEMORRHAGE; CELLS; HIF-1; FLUID AB Objectives: Brain edema is a primary factor in the morbidity and mortality of traumatic brain injury (TBI). The various isoforms of aquaporin 4 (AQP4) and aquaporin 9 (AQP9) are important factors influencing edema following TBI. Others have reported that these AQPs are regulated by the transcription factor hypoxia inducible factor (HIF)1 alpha. Therefore, we examined the temporal alterations in the multiple isoforms of AQP4 and AQP9, and its possible upstream regulation by HIF1 alpha, and evaluated whether different severities of penetrating injury influence these mechanisms. Methods: In the penetrating ballistic-like brain injury (PBBI) model, a temporary cavity and resultant injury was formed by the rapid inflation/deflation (i.e. <40 ms) of an elastic balloon attached to the end of the custom probe, injuring 10% of total rat brain volume. Tissue from the ipsilateral core and perilesional injury zones was collected. Total RNA was isolated at 4, 12, and 24 h, 3 and 7 days post-injury (sham and PBBI, n = 6 per group). cDNA was synthesized using oligodT primers. Quantitative real time PCR was performed using Taqman expression assays for aqp4 (recognizing all isoforms), aqp9, and hif1 alpha. Using separate animals, tissue lysate was collected at 4 and 24 h, 3 and 7 days post-injury and analyzed by immunoblot for protein expression of multiple isoforms of AQP4, the single known isoform of AQP9 and for expression of transcription factor HIF1 alpha (sham, probe only control, and PBBI, n = 8-10 per group). Results: Global aqp4 mRNA was decreased at 24 h (p < 0.01) with PBBI. Three of the four known protein isoforms of AQP4 were detected, M1 (34 kDa), M23 (32 kDa) and isoform 3 (30 kDa). AQP4 M1 decreased at 3 and 7 days post-injury (p < 0.001; p < 0.01). AQP4 M23 levels were highly variable with no significant changes. AQP4 isoform 3 levels were decreased 3 days post-PBBI (p < 0.05). From 4, 12, and 24 h aqp9 mRNA levels were decreased with injury (p < 0.01, p < 0.05, p < 0.01) while AQP9 levels were decreased at 3 and 7 days after PBBI (p < 0.001, p < 0.01). At 12 and 24 h post-PBBI hif1 alpha mRNA levels increased (p < 0.05, p < 0.01) but at 3 and 7 days mRNA levels decreased (p < 0.05, p < 0.01). From 24 h and 3 and 7 days HIF1 alpha protein levels were decreased (p < 0.0001, p < 0.0001, p < 0.0001). In comparison to probe control, PBBI led to greater decreases in protein for AQP4 M1 (trend), AQP4 isoform 3 (trend), AQP9 (p < 0.05) and HIFI (p < 0.05). Conclusion: PBBI is characterized by a loss of AQP4 Ml, AQP4 isoform 3 and AQP9 at delayed time-points. The severity of the injury (PBBI versus probe control) increased these effects. Therefore, AQP9 and the AQP4 M1 isoform may be regulated by HIF1 alpha, but not AQP4 isoform 3. This delayed loss of aquaporins may markedly reduce the ability of the brain to efflux water, contributing to the protracted edema that is a characteristic following severe penetrating TBI. Factors contributing to edema differ with different types and severities of TBI. For example, cellular based edema is more prominent in diffuse non-penetrating TBI whereas vasogenic edema is more prevalent with TBI involving hemorrhage. Molecular regulation leading to edema will likely also differ, such that treatments which have been suggested for non-hemorrhagic moderate TBI, such as the suppression of aquaporins, may be detrimental in more severe forms of TBI.

However, the majority of studies assessing energy requirements of SOF have been conducted on soldiers going through intense SOF initiation training. The objective of the current investigation was to determine the energy expenditure of SOF conducting military training operations. Thirty-one soldiers taking part in Pre-Mission Training (PMT n = 15) and Combat Diver Qualification Courses (CDQC n = 16) volunteered to participate in this observational study. Energy expenditure was determined using doubly labeled water. Body weight (83 7 kg) remained stable during both training periods. Overall energy expenditure adjusted for body composition was 17,606 +/- 2326 kJ center dot day(-1). Energy expenditure was 19,110 +/- 1468 kJ center dot day(-1) during CDQC and 16,334 +/- 2180 kJ center dot day(-1) during PMT, with physical activity levels of 2.6 +/- 0.2 and 2.2 +/- 0.3 during CDQC and PMT, respectively. Compared to the Military Dietary Reference Intakes for energy (13,598 kJ center dot day(-1)), these data are in agreement with previous reports that energy requirement for SOF Soldiers exceed that of the average soldier.

The Trauma Hemostasis and Oxygenation Research Network is a multidisciplinary group of investigators with a common interest in improving outcomes and safety in patients with severe traumatic injury. The network's mission is to reduce the risk of morbidity and mortality from traumatic hemorrhagic shock, in the prehospital phase of resuscitation through research, education, and training. The concept of remote damage control resuscitation is in its infancy, and there is a significant amount of work that needs to be done to improve outcomes for patients with life-threatening bleeding secondary to injury. The prehospital phase of resuscitation is critical in these patients. If shock and coagulopathy can be rapidly identified and minimized before hospital admission, this will very likely reduce morbidity and mortality. This position statement begins to standardize the terms used, provides an acceptable range of therapeutic options, and identifies the major knowledge gaps in the field.

TI REFRIGERATED PLATELETS FOR THE TREATMENT OF ACUTE BLEEDING: A REVIEW OF THE LITERATURE AND REEXAMINATION OF CURRENT STANDARDS SO SHOCK LA English DT Review DE Cold platelets; severe hemorrhage; acute hemorrhage; hypoproliferative thrombocytopenia; trauma; platelet storage temperature; damage control resuscitation; massive transfusion protocols ID FRESH WHOLE-BLOOD; TRAUMA PATIENTS; HEMOSTATIC EFFECTIVENESS; APHERESIS PLATELETS; IMPROVED SURVIVAL; INCREASED PLASMA; TRANSFUSION; STORAGE; TEMPERATURE; 22-DEGREES-C AB This review is a synopsis of the decisions that shaped global policy on platelet (PLT) storage temperature and a focused appraisal of the literature on which those discussions were based. We hypothesize that choices were centered on optimization of preventive PLT transfusion strategies, possibly to the detriment of the therapeutic needs of acutely bleeding patients. Refrigerated PLTs are a better hemostatic product, and they are safer in that they are less prone to bacterial contamination. They were abandoned during the 1970s because of the belief that clinically effective PLTs should both be hemostatically functional and survive in circulation for several days as indicated for prophylactic transfusion; however, clinical practice may be changing. Data from two randomized controlled trials bring into question the concept that stable autologous stem cell transplant patients with hypoproliferative thrombocytopenia should continue to receive prophylactic transfusions. At the same time, new findings regarding the efficacy of cold PLTs and their potential role in treating acute bleeding have revived the debate regarding optimal PLT storage temperature. In summary, a "one-size-fits-all'' strategy for PLT storage may not be adequate, and a reexamination of whether cold-stored PLTs should be offered as a widely available therapeutic product may be indicated.

TI HEMOSTATIC FUNCTION OF APHERESIS PLATELETS STORED AT 4 degrees C AND 22 degrees C SO SHOCK LA English DT Article DE Hemostasis; coagulation; aggregation; clot strength; cold storage; activation ID CHILLED BLOOD-PLATELETS; IN-VITRO; BUFFY-COAT; STORAGE-TEMPERATURE; SHAPE CHANGE; WHOLE-BLOOD; TRANSFUSION; ACTIVATION; AGGREGATION; RECEPTORS AB Introduction: Platelet refrigeration decreases the risk of bacterial contamination and may preserve function better than standard-of-care room temperature (RT) storage. Benefits could include lower transfusion-related complications, decreased costs, improved hemostasis in acutely bleeding patients, and extended shelf life. In this study, we compared the effects of 22 degrees C and 4 degrees C storage on the functional and activation status of apheresis platelets. Methods: Apheresis platelets (n = 5 per group) were stored for 5 days at 22 degrees C with agitation (RT) versus at 4 degrees C with agitation (4 degrees C + AG) and without (4 degrees C). Measurements included platelet counts, mean platelet volume, blood gas analytes, aggregation response, thromboelastography, thromboxane B-2 and soluble CD40 ligand release, activation markers, and microparticle formation. Results: Sample pH levels were within acceptable limits for storage products (pH 6.2-7.4). Platelet glucose metabolism (P < 0.05), aggregation response (adenosine diphosphate: RT 0; 4 degrees C + AG 5.0 +/- 0.8; 4 degrees C 5.6 +/- 0.9; P < 0.05), and clot strength (maximum amplitude: RT 58 +/- 2; 4 degrees C + AG 63 +/- 2; 4 degrees C 67 +/- 2; P < 0.05) were better preserved at 4 degrees C compared with RT storage. Refrigerated samples were more activated compared with RT (P < 0.05), although thromboxane B-2 (P < 0.05) and soluble CD40 ligand release (P < 0.05) were higher at RT. Agitation did not improve the quality of 4 degrees C-stored samples. Conclusions: Apheresis platelets stored at 4 degrees C maintain more viable metabolic characteristics, are hemostatically more effective, and release fewer proinflammatory mediators than apheresis platelets stored at RT over 5 days. Given the superior bacteriologic safety of refrigerated products, these data suggest that cold-stored platelets may improve outcomes for acutely bleeding patients.

TI LOW TITER GROUP O WHOLE BLOOD IN EMERGENCY SITUATIONS SO SHOCK LA English DT Article DE Whole blood; ABO-titers; universal blood; blood transfusion; damage control resuscitation ID DAMAGE CONTROL RESUSCITATION; ABO-INCOMPATIBLE PLASMA; APHERESIS PLATELETS; TRAUMA PATIENTS; IMPROVED SURVIVAL; ANTI-A; TRANSFUSION; HEMOLYSIS; AFGHANISTAN; ANTIBODIES AB In past and ongoing military conflicts, the use of whole blood (WB) as a resuscitative product to treat trauma-induced shock and coagulopathy has been widely accepted as an alternative when availability of a balanced component-based transfusion strategy is restricted or lacking. In previous military conflicts, ABO group O blood from donors with low titers of anti-A/B blood group antibodies was favored. Now, several policies demand the exclusive use of ABO group-specific WB. In this short review, we argue that the overall risks, dangers, and consequences of "the ABO group-specific approach,'' in emergencies, make the use of universal group O WB from donors with low titers of anti-A/B safer. Generally, risks with ABO group-specific transfusions are associated with in vivo destruction of the red blood cells transfused. The risk with group O WB is from the plasma transfused to ABO-incompatible patients. In the civilian setting, the risk of clinical hemolytic transfusion reactions (HTRs) due to ABO group-specific red blood cell transfusions is relatively low (approximately 1: 80,000), but the consequences are frequently severe. Civilian risk of HTRs due to plasma incompatible transfusions, using titered donors, is approximately 1: 120,000 but usually of mild to moderate severity. Emergency settings are often chaotic and resource limited, factors well known to increase the potential for human errors. Using ABO group-specific WB in emergencies may delay treatment because of needed ABO typing, increase the risk of clinical HTRs, and increase the severity of these reactions as well as increase the danger of underresuscitation due to lack of some ABO groups. When the clinical decision has been made to transfuse WB in patients with life-threatening hemorrhagic shock, we recommend the use of group O WB from donors with low anti-A/B titers when logistical constraints preclude the rapid availability of ABO groupYspecific WB and reliable group matching between donor and recipient is not feasible.

TI EMERGENCY WHOLE-BLOOD USE IN THE FIELD: A SIMPLIFIED PROTOCOL FOR COLLECTION AND TRANSFUSION SO SHOCK LA English DT Article DE Shock; prehospital; remote; damage control; trauma; combat ID IMPROVED SURVIVAL; PLATELETS; PLASMA; PRODUCTS AB Military experience and recent in vitro laboratory data provide a biological rationale for whole-blood use in the treatment of exsanguinating hemorrhage and have renewed interest in the reintroduction of fresh whole blood and cold-stored whole blood to patient care in austere environments. There is scant evidence to support, in a field environment, that a whole bloodYbased resuscitation strategy is superior to a crystalloid/colloid approach even when augmented by a limited number of red blood cell (RBC) and plasma units. Recent retrospective evidence suggests that, in this setting, resuscitation with a full compliment of RBCs, plasma, and platelets may offer an advantage, especially under conditions where evacuation is delayed. No current evacuation system, military or civilian, is capable of providing RBC, plasma, and platelet units in a prehospital environment, especially in austere settings. As a result, for the vast minority of casualties, in austere settings, with life-threatening hemorrhage, it is appropriate to consider a whole bloodYbased resuscitation approach to provide a balanced response to altered hemostasis and oxygen debt, with the goal of reducing the risk of death from hemorrhagic shock. To optimize the successful use of fresh whole blood/cold-stored whole blood in combat field environments, proper planning and frequent training to maximize efficiency and safety will be required. Combat medics will need proper protocol-based guidance and education if whole-blood collection and transfusion are to be successfully and safely performed in austere environments. In this article, we present the Norwegian Naval Special Operation Commando unitYspecific remote damage control resuscitation protocol, which includes field collection and transfusion of whole blood. This protocol can serve as a template for others to use and adjust for their own military or civilian unitYspecific needs and capabilities for care in austere environments.

TI On power and actuation requirement in swashplateless primary control of helicopters using trailing-edge flapes SO AERONAUTICAL JOURNAL LA English DT Article ID MACH-SCALED ROTOR AB This paper examines three specific aspects pertaining to the trailing-edge flap (TEF) enabled swashplateless primary control of a helicopter. The study is based on a utility helicopter very similar to the UH-60A Blackhawk helicopter, with rotor torsion frequency reduced to 2.1/rev, and 20% chord TEFs extending from 70-90% span. The questions addressed in the paper are the power penalty due to aerodynamic drag associated with TEF control, the pitch-index required to limit the range of TEF deflections over variations in aircraft gross-weight and airspeed, and the influence of rotor RPM variation on swashplateless primary control. Results indicate that the power penalty associated with TEF enabled primary control at high speeds is in the range of 6-7%, due to increased drag on the advancing side in the region of the TEFs and at the blade tips. At low to moderate speeds the increase in power is 2-4% on average, more dependent on the pitch-index, and due to drag increase over most of the azimuth in the region of the TEFs. A variation in pitch-index from 16 degrees for lower speeds and gross weights, to 20-22 degrees for higher speeds and gross weights, would reduce the steady level flight TEF deflection requirements to under +/- 3 degrees, leaving sufficient control margin. Increase in rotor RPM does not increase directly increase thrust (as with a stiff-torsion rotor) but reduces the rotating torsion frequency, and together with the increased dynamic pressures increases the sensitivity to TEF control. At low to moderate speeds a 9% increase in RPM reduces the maximum TEF deflections required by about 1 degrees, but is accompanied by a large increase in rotor power. Conversely, a 9% RPM reduction decreases rotor power required, but the TEF deflections required increase by 1-1-5 degrees. C1 [Gandhi, F.] Rensselaer Polytech Inst, Troy, NY 12180 USA.

Two designs were tested in batch cycles using landfill leachate as a substrate without inoculation (908 to 3,200 mg/L chemical oxygen demand (COD)): Circle (934 mL) and large-scale microbial fuel cells (MFC) (18.3 L). A total of seven cycles were completed for the Circle MFC and two cycles for the larger-scale MFC. Maximum power densities of 24 to 31 mW/m(2) (653 to 824 mW/m(3)) were achieved using the Circle MFC, and a maximum voltage of 635 mV was produced using the larger-scale MFC. In the Circle MFC, COD, biological oxygen demand (BOD), total organic carbon (TOC), and ammonia were removed at an average of 16%, 62%, 23%, and 20%, respectively. The larger-scale MFC achieved an average of 74% BOD removal, 27% TOC removal, and 25% ammonia reduction while operating over 52 days. Analysis of the microbial characteristics of the leachate indicates that there might be both supportive and inhibiting bacteria in landfill leachate for operation of an MFC. Issues related to scale-up and heterogeneity of a mixed substrate remain. C1 [Damiano, Lisa] Univ New Hampshire, Durham, NH 03824 USA. [Jambeck, Jenna R.] Univ Georgia, Athens, GA 30602 USA.

TI Synthesizing antipodal chaotic waveforms SO JOURNAL OF THE FRANKLIN INSTITUTE-ENGINEERING AND APPLIED MATHEMATICS LA English DT Article ID CARDIAC ALTERNANS; DYNAMIC CONTROL; COMMUNICATION; SYSTEMS AB Chaotic waveforms are natural information carriers since a correspondence can be established between the symbolic dynamics of a chaotic oscillator and the symbols of a message. Message symbols can be efficiently encoded in a chaotic waveform by applying vanishingly small perturbations to an oscillator to guide its symbolic dynamics to follow a desired course. Recently, two chaotic hybrid dynamical systems were shown to have matched filters enabling robust reception of chaotic communication waveforms in the presence of noise. The first of these, the exact shift oscillator, produces waveforms with desirable properties similar to antipodal signaling, but a physical implementation may be difficult to control using small perturbations. The second oscillator, the exact folded-band oscillator, produces less optimal waveforms but is more easily controlled. Here we introduce a method for generating waveforms of the exact shift oscillator by summing waveforms from a bank of easily controlled exact folded-band oscillators. We show that any solution of the exact shift oscillator can be so constructed using only three folded-band oscillators.

TI Assessment of an Alternative Postdeployment Reintegration Strategy With Soldiers Returning From Iraq SO PSYCHOLOGICAL SERVICES LA English DT Article DE behavioral health; alcohol; aggression; risk behavior; deployment reintegration ID MENTAL-HEALTH PROBLEMS; COMBAT; AFGHANISTAN; PREVALENCE; DEPLOYMENT; BEHAVIORS; CHECKLIST; COMPONENT; VETERANS; CARE AB The present study examined behavioral health outcomes, risk behaviors, aggression, alcohol misuse, marital satisfaction, and attitudes toward reintegration associated with an alternative, front-loaded reintegration strategy compared with a more standardized reintegration process in soldiers returning from combat deployments. The type of reintegration strategy used did not predict differences in posttraumatic stress disorder (PTSD) symptoms, alcohol misuse, aggression, and marital satisfaction, although slightly higher reports of risk behaviors were found in the unit using the standard reintegration approach even after controlling for demographic covariates and combat exposure. These findings may help guide leadership when making decisions regarding reintegration approaches in the future.

TI Perceived Organizational Support, Posttraumatic Stress Disorder Symptoms, and Stigma in Soldiers Returning From Combat SO PSYCHOLOGICAL SERVICES LA English DT Article DE perceived organizational support; stigma; symptoms ID MENTAL-HEALTH PROBLEMS; NATIONAL-GUARD SOLDIERS; GULF-WAR; BARRIERS; IRAQ; CARE; EXPOSURE; SATISFACTION; AFGHANISTAN; COMMITMENT AB Research has shown that perceived organizational support (POS), or how much employees believe their organizations value their contributions and well-being, is an important predictor of employee mental health outcomes. To support employee mental health in high-risk occupations, organizations may want to identify variables that explain the relationship between POS and posttraumatic stress disorder (PTSD). Using a longitudinal design and a military sample, the present study found a relationship between POS and stigma as well as PTSD symptoms. Stigma partially mediated the relationship between POS at Time 1 and PTSD symptoms at Time 2. The partial mediation indicates that a supportive environment may also create a climate of reduced stigma in which soldiers may be comfortable addressing PTSD symptoms. Both results suggest positive actions that organizations can take to support employee mental health. C1 [Kelley, Christie L.; Britt, Thomas W.] Clemson Univ, Dept Psychol, Clemson, SC 29631 USA.

TI The Epidemiology of Medial Collateral Ligament Sprains in Young Athletes SO AMERICAN JOURNAL OF SPORTS MEDICINE LA English DT Article DE knee injuries; risk factor; epidemiology; medial collateral ligament ID ICE HOCKEY INJURIES; KNEE INJURIES; COLLEGE FOOTBALL; SKIING INJURIES; SPORTS; TEAM; LEAGUE; BRACE; RATES; RISK AB Background: A medial collateral ligament (MCL) knee sprain is a prevalent injury in athletic populations that may result in significant time lost to injury. Remarkably little is known of the epidemiology of this injury. Purpose: To define the incidence of MCL tears and to determine the demographic and athletic risk factors. Study Design: Descriptive epidemiological study. Methods: A longitudinal cohort study was performed to examine the epidemiology of isolated MCL sprains at the United States Military Academy (USMA) between 2005 and 2009. Charts and radiographic studies were reviewed by an independent orthopaedic surgeon to identify all new isolated MCL sprains resulting in time lost to sport and activity that occurred within the study period. Incidence rates (IRs) with 95% confidence intervals (CIs) were calculated per 1000 person-years at risk and by sex, sport, and level of competition. The IR per 1000 athlete-exposures (AEs) was also determined. Incidence rate ratios (IRRs) and respective 95% CIs were calculated between male and female students, intercollegiate and intramural athletes, and male and female intercollegiate athletes involved in selected sports. Chi-square and Poisson regression analyses were used to examine the relationship between the variables of interest and the incidence of MCL sprains, with statistical significance set at P < .05. Results: A total of 128 cadets sustained isolated MCL injuries during 17,606 student person-years from 2005 to 2009. This resulted in an IR of approximately 7.3 per 1000 person-years. Of the 128 injuries, 114 were in male athletes (89%) and 14 were in female athletes (11%). Male cadets had a 44% higher IR than did female cadets (7.60 vs 5.36, respectively), although this was not significant (P = .212). Of 5820 at-risk intercollegiate athletes, 59 (53 male, 6 female) sustained an isolated MCL sprain during 528,523 (407,475 male, 121,048 female) AEs for an overall IR of 10.14 per 1000 person-years and 0.11 per 1000 AEs. The IRR of MCL sprains of men compared with women involved in intercollegiate athletics was 2.87 (95% CI, 1.24-8.18) per 1000 person-years and 2.62 (95% CI, 1.13-7.47) per 1000 AEs. Of 21,805 at-risk intramural athletes, with quarterly participation, 16 (all male) sustained isolated MCL injuries during 225,683 AEs for an overall IR of 0.07 per 1000 AEs. The IRs of MCL injuries of intercollegiate and intramural athletes did not differ significantly. In intercollegiate sports, wrestling (0.57), judo (0.36), hockey (0.34), and rugby (men's, 0.22; women's, 0.23) had the highest IRs per 1000 AEs. When examining men's intercollegiate athletics, the IRRs of wrestling (13.41; 95% CI, 1.80-595.27) and hockey (8.12; 95% CI, 0.91-384.16) were significantly higher compared with that of lacrosse. Among women's intercollegiate sports as well as intramural sports, there were no significant differences in IRs. A median of 16 days was lost to injury, with 2407 total days lost for all injuries. Grade 1 MCL injuries lost a median of 13.5 days, while higher grade injuries lost a median of 29 days. Conclusion: Medial collateral ligament injuries are relatively common in athletic cohorts. The most injurious sports are contact sports such as wrestling, hockey, judo, and rugby. Male athletes are at a greater risk than female athletes. Intercollegiate athletes are at a greater risk than intramural athletes. The average amount of time lost per injury was 23.2 days, with greater time lost with higher grade sprains than grade 1 sprains.

TI A probabilistic technique for entrained air void analysis in hardened concrete SO CEMENT AND CONCRETE RESEARCH LA English DT Article DE Characterization (B); Image analysis (B); Microstructure (B); Durability (C); Freezing and thawing (C) ID FLAT-BED SCANNER AB A novel method that utilizes the lineal-path function to ascertain a probability density function for the three-dimensional size distribution of entrained air voids directly from plane polished sections of hardened concrete is proposed. The results then treat the sparing factor in terms of a probabilistic maximum distance from a random point in the cement paste matrix to the periphery of an air void, where air voids are treated as a polydispersed sphere system. The model was applied to concretes with various air entrainment admixture types and dosages. The results suggest that the model may offer a better assessment of the system for use in assessing durability and studying admixtures, as well as providing a new tool for spatial characterization of heterogeneous and porous materials.

TI INFLUENCE OF CARBON AND METAL OXIDE NANOMATERIALS ON AQUEOUS CONCENTRATIONS OF THE MUNITION CONSTITUENTS CYCLOTRIMETHYLENETRINITRAMINE (RDX) AND TUNGSTEN SO ENVIRONMENTAL TOXICOLOGY AND CHEMISTRY LA English DT Article DE Nanomaterial; Environmental fate; Munitions constituent; Military; Adsorption ID TITANIUM-DIOXIDE NANOPARTICLES; ACTIVATED CARBON; ORGANIC-MATTER; ALUMINUM-OXIDE; NANOTUBES; ADSORPTION; SORPTION; NANO; REMOVAL; BIOACCUMULATION AB There is an increasing likelihood of interactions between nanomaterials and munitions constituents in the environment resulting from the use of nanomaterials as additives to energetic formulations and potential contact in waste streams from production facilities and runoff from training ranges. The purpose of the present research was to determine the ability of nano-aluminum oxide (Al2O3) and multiwalled carbon nanotubes (MWCNTs) to adsorb the munitions constituents cyclotrimethylenetrinitramine (RDX) and tungsten (W) from aqueous solution as a first step in determining the long-term exposure, transport, and bioavailability implications of such interactions. The results indicate significant adsorption of RDX by MWCNTs and of W by nano-Al2O3 (but not between W and MWCNT or RDX and nano-Al2O3). Kinetic sorption and desorption investigations indicated that the most sorption occurs nearly instantaneously (<5min), with a relatively slower, secondary binding leading to statistically significant but relatively smaller increases in adsorption over 30 d. The RDX sorption that occurred during the initial interaction was irreversible, with long-term, reversible sorption likely the result of a secondary interaction; as interaction time increased, however, the portion of W irreversibly sorbed onto nano-Al2O3 also increased. The present study shows that strong interactions between some munitions constituents and nanomaterials following environmental release are likely. Time-dependent binding has implications for the bioavailability, migration, transport, and fate of munitions constituents in the environment. Environ Toxicol Chem 2014;33:1035-1042.

TI Evaluation of an Oxygen-Diffusion Dressing for Accelerated Healing of Donor-Site Wounds SO JOURNAL OF BURN CARE & RESEARCH LA English DT Article AB Accelerating the healing process and reducing pain during healing are beneficial for the following reasons: faster return to work, lower risk of wound infection, improved quality of life, and possibly reduced need for analgesia. This clinical study assessed the effectiveness of a new oxygen-diffusion dressing (OxyBand; Oxyband Technologies, St. Louis, MO) compared with standard Xeroform gauze dressings (Convidien, Mansfield, MA), in the care of skin-graft donor sites in burn patients. Time to healing was the primary endpoint, and pain scores and cosmetic outcome were also assessed. This was a prospective, randomized, controlled study of burn patients undergoing harvesting of two donor sites. Patients were followed at predetermined time points for 30 to 45 days to determine the time to reepithelialization, cosmetic appearance, and pain. Subjects were adult burn patients with less than 30% TBSA burns admitted to the burn center, who required excision and grafting. Twenty patients were enrolled, of whom 17 completed the study. Average age was 35 years. Average burn size was 9.2% TBSA. Patients underwent harvesting of split-thickness skin grafts with one donor wound dressed with OxyBand and the other dressed in Xeroform gauze. Wounds were inspected and photographed on postoperative days 4 and 8, and then every 2 days until the donor wounds were healed. Pain scores at each site were also collected at these visits (rated by patients on a scale from 0 to 10). Mean time to wound healing for OxyBand was 9.3 +/- 1.7 days; for Xeroform, 12.4 +/- 2.7 days (P < .001). Pain scores were lower (P < .01) at the OxyBand site compared with the Xeroform site at all time points during postoperative days 4 to 12. There was no difference in the cosmetic outcome of the wounds at 30 to 45 days postoperatively. This study revealed a decrease in the time to healing and in pain at donor sites dressed with an oxygen-diffusion dressing.

TI Simple and Effective Approach for Polar Decomposition of the Deformation Gradient Tensor SO JOURNAL OF ENGINEERING MECHANICS LA English DT Article DE Deformation; Nonlinear analysis; Finite element method; Structural dynamics; Transient response; Decomposition; Nonlinear analysis; Finite-element method (FEM); Structural dynamics; Transient response ID PARALLEL COMPUTATION; FINITE; METHODOLOGIES; INTEGRATION; ROTATION AB A precise iterative strategy to compute the polar decomposition of the three-dimensional deformation gradient tensor is presented for nonlinear solid mechanics analysis software. By exploiting relationships between various stretch tensors, polar decomposition is transformed into the solution of six nonlinear (quadratic) simultaneous equations, via Newton-Raphson (N-R), and a subsequent 3x3 matrix inversion and multiplication. The approach is easy to program and is versatile in its applicability to statics or dynamics. With only modest computational increases, the approximations and potential numerical drift of incremental decomposition schemes is avoided. Convergence can be accelerated using stretch histories, which, coupled with a modified N-R approach, can reduce computer times. Using an explicit central difference time integration scheme, convergence is shown to be attained in only a few iterations with very tight tolerances for severe deformations. Numerical examples compare different method variations that are demonstrated to be robust and efficient. The results also demonstrate its effectiveness for large time increments (the entire analysis), which can be especially useful for static and implicit solvers.

TI Urinary Polycyclic Aromatic Hydrocarbon (OH-PAH) Metabolite Concentrations and the Effect of GST Polymorphisms Among US Air Force Personnel Exposed to Jet Fuel SO JOURNAL OF OCCUPATIONAL AND ENVIRONMENTAL MEDICINE LA English DT Article ID GENETIC POLYMORPHISMS; INHALATION EXPOSURE; NAPHTHALENE; BIOMARKERS; 1-HYDROXYPYRENE; 2-NAPHTHOL; NAPHTHOLS; CYP1A1; CYP2E1; JP-8 AB Objective: To evaluate the association between inhalation exposure to jet propulsion fuel 8 (JP-8) and urinary metabolites among US Air Force (USAF) personnel, and investigate the role of glutathione S-transferase polymorphisms. Methods: Personal air samples were collected from 37 full-time USAF personnel during 4 consecutive workdays and analyzed for JP-8 constituents and total hydrocarbons. Pre- and postshift urine samples were collected each day and analyzed for polycyclic aromatic hydrocarbon urinary metabolites. Results: Work shift exposure to total hydrocarbons was significantly associated with postshift urinary 1-naphthol ( = 0.17; P = <0.0001), 2-naphthol ( = 0.09; P = 0.005), and 2-hydroxyfluorene concentrations ( = 0.08; P = 0.006), and a significant gene-environment interaction was observed with glutathione S-transferase mu-1. Conclusions: USAF personnel experience inhalation exposure to JP-8, which is associated with absorption of JP-8 constituents while performing typical job-related tasks, and in our data the glutathione S-transferase mu-1 polymorphism was associated with differential metabolism of naphthalene.

TI Trends in Caffeine Use and Association between Clinical Outcomes and Timing of Therapy in Very Low Birth Weight Infants SO JOURNAL OF PEDIATRICS LA English DT Article ID EXTREMELY PRETERM INFANTS; PATENT DUCTUS-ARTERIOSUS; BLOOD-FLOW-VELOCITY; BRONCHOPULMONARY DYSPLASIA; INTENSIVE-CARE; PREMATURITY; APNEA; PREVENTION; MORTALITY; AGE AB Objective To examine the effect of early initiation of caffeine therapy on neonatal outcomes and characterize the use of caffeine therapy in very low birth weight (VLBW) infants. Study design We analyzed a cohort of 62 056 VLBW infants discharged between 1997 and 2010 who received caffeine therapy. We compared outcomes in infants receiving early caffeine therapy (initial dose before 3 days of life) and those receiving late caffeine therapy (initial dose at or after 3 days of life) through propensity scoring using baseline and early clinical variables. The primary outcome was the association between the timing of caffeine initiation and the incidence of bronchopulmonary dysplasia (BPD) or death. Results We propensity score-matched 29 070 VLBW infants at a 1: 1. Of infants receiving early caffeine therapy, 3681 (27.6%) died or developed BPD, compared with 4591 infants (34.0%) receiving late caffeine therapy (OR, 0.74; 99% CI, 0.69-0.80). Infants receiving early caffeine had a lower incidence of BPD (23.1% vs 30.7%; OR, 0.68; 95% CI, 0.63-0.73) and a higher incidence of death (4.5% vs 3.7%; OR, 1.23; 95% CI, 1.05-1.43). Infants receiving early caffeine therapy had less treatment of patent ductus arteriosus (OR, 0.60; 95% CI, 0.55-0.65) and a shorter duration of mechanical ventilation (mean difference, 6 days; P < .001). Conclusion Early caffeine initiation is associated with a decreased incidence of BPD. Randomized trials are needed to determine the efficacy and safety of early caffeine prophylaxis in VLBW infants.

SO JOURNAL OF SURGICAL EDUCATION LA English DT Article DE orthopaedic in-training examination; American Board of Orthopaedic Surgeons; study resources; orthopaedic review ID IN-TRAINING EXAMINATION; CERTIFYING EXAMINATION; PERFORMANCE; SECTION; USMLE; PREDICTORS; QUESTIONS; PATHOLOGY; SUCCESS AB BACKGROUND: Previous studies have shown that certain orthopaedic in-training examination scores can be used to identify which residents may be at risk for failing the American Board of Orthopaedic Surgeons (ABOS) Part 1 examination. However, no studies have examined how study resources may affect residents' ABOS Part 1 scores. The goal of this study is to determine which review sources or review courses, if any, are associated with improved ABOS Part 1 scores. METHODS: A survey was sent to 221 of the 865 examinees who took the ABOS Part 1 examination in 2012. The questions inquired the respondents how well they performed on previous orthopaedic in-training examinations and ABOS Part 1, along with the study sources they most commonly used, review courses they attended, and resources they would recommended if they were to retake ABOS Part 1 examination. RESULTS: Overall, 118 of the 221 (53%) survey recipients completed the survey. Six (5%) of the respondents failed ABOS Part 1 examination. Orthobullets and the American Academy of Orthopaedic Surgeons self-assessment examinations were recommended as the primary study source significantly more (p < 0.01) than most other resources, but there was no significant association between study source and passing ABOS Part 1 or scoring in a certain percentile on ABOS Part 1. Similarly, there were no associations between attending a review course and either passing or scoring in a certain percentile for ABOS Part 1. Half of the respondents who failed ABOS Part 1 attended multiple review courses. CONCLUSIONS: There does not appear to be an association between improved ABOS Part 1 scores and orthopedic study materials or review courses. Further research into the value of certain educational modalities should be conducted to determine the best ways to educate orthopedic residents and determine the value of some of these commonly used orthopedic review modalities.

TI Blood-Banking Techniques for Plateletpheresis in Swine SO JOURNAL OF THE AMERICAN ASSOCIATION FOR LABORATORY ANIMAL SCIENCE LA English DT Article ID DAMAGE CONTROL RESUSCITATION; HEMORRHAGIC-SHOCK; HUMAN COAGULATION; PIG PLATELETS; DOMESTIC PIGS; PORCINE BLOOD; ANIMAL-MODELS; STORAGE; CELLS; LEUCOREDUCTION AB During the past several years, trauma resuscitation in human patients has evolved from decreased use of crystalloids to increased use of blood products. Of high interest is the role of platelets in trauma resuscitation. Because conducting prehospital resuscitation in human trauma patients is very difficult, swine are often the animal model of choice for such studies because their coagulation and hemodynamic systems are similar to those in humans. However, consistent production of sufficient swine platelets for such studies has not previously been achieved. We developed a method for producing swine platelets by using standard human techniques and equipment. We assessed pH, pO(2), pCO(2), lactate, thromboelastography, and platelet aggregation over 5 d of storage to determine whether the swine platelet product met the American Association of Blood Banks (AABB) standards for transfusion. Swine platelets met AABB standards at 24 h but not at later time points. In addition, we fluorescently labeled nonautologous platelets and then measured their percentage recovery over 5 h (the time used in subsequent experimental studies) when transfused into a recipient pig. We showed that 80% of the platelets stored for 24 h remained in the circulation and increased the recipient pigs' thromboelastographic responses, indicating that the platelets were viable and active. Therefore, swine platelets stored for 24 h by using standard human products met the AABB criteria and were functional.

Vicariance between the island of Borneo, the remaining Indonesian archipelago and mainland Southeast Asia caused by elevated sea levels during interglacial periods has been proposed to lead to diversification in the littoral zone mosquito Anopheles (Cellia) sundaicus (Rodenwaldt) sensu lato. To test this biogeographical hypothesis, we inferred the population history and assessed gene flow of A.sundaicus s.l. sampled from 18 populations across its pan-Asian species range, using sequences from mitochondrial cytochrome c oxidase subunit 1 (CO1), the internal transcribed spacer 2 (ITS2) and the mannose phosphate isomerase (Mpi) gene. A hypothesis of ecological speciation for A.sundaicus involving divergent adaptation to brackish and freshwater larval habitats was also previously proposed, based on a deficiency of heterozygotes for Mpi allozyme alleles in sympatry. This hypothesis was not supported by Mpi sequence data, which exhibited no fixed differences between brackish and freshwater larval habitats. Mpi and CO1 supported the presence of up to eight genetically distinct population groupings. Counter to the hypothesis of three allopatric species, divergence was often no greater between Borneo, Sumatra/Java and the Southeast Asian mainland than it was between genetic groupings within these landmasses. An isolation-with-migration (IM) model indicates recurrent gene flow between the current major landmasses. Such gene flow would have been possible during glacial periods when the current landmasses merged, presenting opportunities for dispersal along expanding and contracting coastlines. Consequently, Pleistocene climatic variation has proved a homogenizing, rather than diversifying, force for A.sundaicus diversity.

We describe this phenomenon with a general treatment of light scattering from a multiresonant nanostructure that is spherical or nonspherical but subwavelength in size. With multiple resonances in the same channel (i.e., same angular momentum and polarization), coherent interference always leads to scattering dark states in the low-absorption limit, regardless of the system details. The coupling between resonances is inevitable and can be interpreted as arising from far-field or near-field. This is a realization of coupled-resonator-induced transparency in the context of light scattering, which is related to but different from Fano resonances. Explicit examples are given to illustrate these concepts. C1 [Hsu, Chia Wei; Joannopoulos, John D.; Soljacic, Marin] MIT, Dept Phys, Cambridge, MA 02139 USA.

Study Design Prospective randomized trial. Setting Academic, tertiary medical center. Methods Forty first-year residents across a variety of disciplines with fewer than 5 total live intubations were recruited for the study. Testing took place during orientation prior to commencement of clinical duties. The entire group was provided training by faculty otolaryngologists and anesthesiologists using both laryngoscope types on a manikin airway simulator in a standard intubating scenario. Subjects were then randomized into 2 testing groups, using either a Macintosh laryngoscope or video-assisted laryngoscope in a difficult intubation scenario. The difficult airway simulation entailed oral cavity/oropharyngeal obstruction using inflation of the tongue, as well as cervical spine immobilization with a rigid collar preventing extension and elevation of the head and limiting oral cavity opening. Success was defined as a confirmed endotracheal intubation by the testing instructor in 120 seconds or less. Results The Macintosh laryngoscope group (n = 19) had an intubation success rate of 47.4% with a mean intubation time of 69.0 seconds (95% confidence interval [CI]: 52.7, 85.2). The video-assisted group (n = 21) demonstrated a significantly higher success rate of 100% (P < .0001) and a decreased mean intubation time of 23.1 seconds (95% CI: 18.4, 27.8; P < .0001). The mean difference in success rate between groups was 52.6% (95% CI: 30.0%, 75.3%). Conclusions Novice physicians with little to no prior intubation experience showed significantly higher intubation success with lower intubation times using a video-assisted laryngoscope in a difficult airway manikin simulator.

This study compares the experience of otolaryngology residents at military programs with the experience of their civilian counterparts. Study Design Retrospective review. Setting Academic military medical centers. Subjects and Methods Resident caseload data and board examination passing rates were requested from each of the 6 Department of Defense otolaryngology residency programs for 2001 to 2010. The American Board of Otolaryngology and the Accreditation Council for Graduate Medical Education provided the national averages for resident caseload. National board passing rates from 2004 to 2010 were also obtained. Two-sample t tests were used to compare the pooled caseloads from the military programs with the national averages. Board passing rates were compared with a test of proportions. Results Data were available for all but one military program. Regarding total cases, only 2001 and 2003 showed a significant difference (P < .05), with military residents completing more cases in those years. For individual case categories, the military averages were higher in Otology (299.6 vs 261.2, P = .033) and Plastics/Reconstruction (248.1 vs 149.2, P = .003). Only the Head & Neck category significantly favored the national average over the military (278.3 and 226.0, P = .039). The first-time board passing rates were identical between the groups (93%). Conclusion Our results suggest that the military otolaryngology residency programs are equal in terms of caseload and board passing rates compared with civilian programs over this time period.

It is known to be an aggressive and nondiscriminatory biter and is by far the most common human-biting tick encountered in Virginia. Few studies of human pathogen prevalence in ticks have been conducted in our state since the mid-twentieth century. We developed a six-plex real-time PCR assay to detect three Ehrlichia species (E. chaffeensis, E. ewingii, and Panola Mountain Ehrlichia) and three spotted fever group Rickettsiae (SFGR; R. amblyommii, R. parkeri, and R. rickettsii) and used it to test A. americanum from around the state. Our studies revealed a presence of all three Ehrlichia species (0-24.5%) and a high prevalence (50-80%) of R. amblyommii, a presumptively nonpathogenic SFGR, in all regions surveyed. R. parkeri, previously only detected in Virginia's Amblyomma maculatum ticks, was found in A. americanum in several surveyed areas within two regions having established A. maculatum populations. R. rickettsii was not found in any sample tested. Our study provides the first state-wide screening of A. americanum ticks in recent history and indicates that human exposure to R. amblyommii and to Ehrlichiae may be common. The high prevalence of R. amblyommii, serological cross-reactivity of all SFGR members, and the apparent rarity of R. rickettsii in human biting ticks across the eastern United States suggest that clinical cases of tick-borne disease, including ehrlichiosis, may be commonly misdiagnosed as Rocky Mountain spotted fever, and that suspicion of other SFGR as well as Ehrlichia should be increased. These data may be of relevance to other regions where A. americanum is prevalent. C1 [Gaines, David N.; Broyhill, James] Virginia Dept Hlth, Richmond, VA 23219 USA.

Multiple factors such as an ideal graft, the appropriate biochemical and mechanical wound environment, and viable cell populations are essential components in promoting healing. While bony tissue performs many functions, critical is mechanical strength, followed closely by structure. Many tools are available to evaluate bone quality in terms of quantity, structure, and strength; the purpose of this article is to identify the factors that can be evaluated and the advantages and disadvantages of each in assessing the quality of bone healing in both preclinical research and clinical settings.

This study was conducted to examine the effect of patterned topographies on bacterial fouling using Enterobacter cloacae as the test model. E. cloacae is an opportunistic pathogen involved frequently in nosocomial infections. It is an important model organism to be studied in the context of healthcare associated infections (HAI) and polydimethylsiloxane (PDMS) based urinary catheter fouling. Patterned surfaces, such as SharkletTM, have shown the promise of being a benign surface treatment for prevention of catheter associated urinary tract infections (CAUTI). To the best of our knowledge, inhibition of fouling by E. cloacae has not been demonstrated on microscale patterned PDMS surfaces. In this study, the SharkletTM and smooth PDMS surfaces were used as controls. All pattern surfaces had statistically significantly lower percentage area coverage compared to the smooth PDMS control. A cross type feature (C-1-PDMS), demonstrated the most significant reduction in percent area coverage, 89% (p < 0.01, alpha= 0.05), compared to the smooth PDMS control and all other patterned test surfaces. Additionally, theoretical calculations show that C-1-PDMS is the only surface predicted to hold the thermodynamically stable Cassie state, which occurs due to trapping air pockets at the liquid solid interface. Combined the results provide new insights for designing environmentally benign, novel, microscale patterned surfaces for restricting bacterial fouling. (C) 2014 Elsevier B.V. All rights reserved.

The Ag/GNP catalyzes the O-2 molecule through a 4-electron reduction to water in 0.1 M KOH electrolyte. The half-wave potential for the ORR on Ag/GNP is similar to a Pt black coated electrode (i.e -0.27V at Ag/GNP, and -0.18V at 40% Pt/C vs.SCE). The kinetic rate for the ORR on Ag/GNP is 3.16 x 10(-2) cm.s(-1) at -0.4V vs. SCE. The effect of alcohols and other impurities on the ORR catalytic activity for Ag/GNP was examined and found to be highly tolerant to methanol, ethanol and ethylene glycol. The Ag/GNP catalyst is also tolerant to tetraalkyl ammonium hydroxides; i.e. functional groups related to the chemical structure of common alkaline electrolyte membranes. Published by Elsevier Ltd.

CA Army STARRS Collaborators TI Predictors of Suicide and Accident Death in the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) Results From the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) SO JAMA PSYCHIATRY LA English DT Article ID US MILITARY; PSYCHOPATHOLOGY; ATTRITION; PERSONNEL; SOLDIERS AB IMPORTANCE The Army Study to Assess Risk and Resilience in Servicemembers ( Army STARRS) is a multicomponent study designed to generate actionable recommendations to reduce Army suicides and increase knowledge of risk and resilience factors for suicidality. OBJECTIVES To present data on prevalence, trends, and basic sociodemographic and Army experience correlates of suicides and accident deaths among active duty Regular Army soldiers between January 1, 2004, and December 31, 2009, and thereby establish a foundation for future Army STARRS investigations. DESIGN, SETTING, AND PARTICIPANTS Analysis of trends and predictors of suicide and accident deaths using Army and Department of Defense administrative data systems. Participants were all members of the US Regular Army serving at any time between 2004 and 2009. MAIN OUTCOMES AND MEASURES Death by suicide or accident during active Army service. RESULTS The suicide rate rose between 2004 and 2009 among never deployed and currently and previously deployed Regular Army soldiers. The accident death rate fell sharply among currently deployed soldiers, remained constant among the previously deployed, and trended upward among the never deployed. Increased suicide risk was associated with being a man (or a woman during deployment), white race/ethnicity, junior enlisted rank, recent demotion, and current or previous deployment. Sociodemographic and Army experience predictors were generally similar for suicides and accident deaths. Time trends in these predictors and in the Army's increased use of accession waivers (which relaxed some qualifications for new soldiers) do not explain the rise in Army suicides. CONCLUSIONS AND RELEVANCE Predictors of Army suicides were largely similar to those reported elsewhere for civilians, although some predictors distinct to Army service emerged that deserve more in-depth analysis. The existence of a time trend in suicide risk among never-deployed soldiers argues indirectly against the view that exposure to combat-related trauma is the exclusive cause of the increase in Army suicides.

The delay performance, ignition sensitivity, and aging characteristics were examined in aluminum microchannels similar in diameter to common delay housings (4.7 mm). Stoichiometries with measured combustion temperatures between 1358 and 2113 K were self-sustaining with combustion velocities ranging from 2.4 to 7.3 mm s(-1). The Mn/MnO2 system produced less gas than W/BaCrO4/KCIO4/diatomaceous earth compositions allowing consideration for use in sealed delay housings. Accelerated aging at 70 degrees C and 30% relative humidity for 8 weeks resulted in no measurable loss of performance. Safety characterization showed that this composition is not sensitive to ignition by friction or electrostatic stimuli. The combustion products (as determined by X-ray diffraction) appear to be benign based on current regulations. Therefore, the Mn/MnO2 system appears to be a suitable low gas-producing, nonsensitive, less toxic delay composition with good longevity.

Sieve testing has revealed a fine granulation for the candidate mixture, centered at 53 mu m. In addition, compressive strain testing has shown that the mechanical (crush) strength of pellets derived from the candidate mixture was 391 kg. Both of these properties validate the viability of the candidate composition during manufacturing and deployment. Extensive static burn testing in full-sized prototype signal assembly hardware provides insight into new ignition train concepts. The full sized prototype assembly has also been demonstrated by flight tests in actual system hardware containing the rocket motor and associated propellant.

Antibody-based immunity to sand fly salivary gland proteins in human populations remains a complex contextual problem that is not yet fully understood. We profiled the immunoreactivities of plasma antibodies to sand fly salivary gland sonicates (SGSs) from 229 human blood donors residing in different regions of sand fly endemicity throughout Jordan and Egypt as well as 69 US military personnel, who were differentially exposed to P. papatasi bites and L. major infections in Iraq. Compared with plasma from control region donors, antibodies were significantly immunoreactive to five salivary proteins (12, 26, 30, 38, and 44 kDa) among Jordanian and Egyptian donors, with immunoglobulin G4 being the dominant anti-SGS isotype. US personnel were significantly immunoreactive to only two salivary proteins (38 and 14 kDa). Using k-means clustering, donors were segregated into four clusters distinguished by unique immunoreactivity profiles to varying combinations of the significantly immunogenic salivary proteins. SGS-induced cellular proliferation was diminished among donors residing in sand fly-endemic regions. These data provide a clearer picture of human immune responses to sand fly vector salivary constituents.

Given these nonspecific symptoms, the diagnosis of vertebrobasilar ischemia may be difficult to distinguish from more benign conditions. A healthy 37-year-old man presented to our clinic with near syncope upon turning his head to the left. Dynamic angiography revealed occlusion of the left vertebral artery at C7 with 90 degrees head rotation to the left, consistent with bow hunter's syndrome. No obvious bony abnormalities were identified on computed tomography or magnetic resonance imaging scans. Transient rotational vertebral artery syndrome, a rare cause of vertebrobasilar insufficiency, has most often been reported at the C1-2 level, and the majority of cases occur in patients >50 years of age because of degenerative osteophytes and contralateral atherosclerosis. We present the unusual case of a young man with symptoms of vertebrobasilar insufficiency and discuss the potential effects of weightlifting and neck muscle hypertrophy on vertebral artery flow dynamics.

SO CURRENT OPINION IN ONCOLOGY LA English DT Review DE aggressiveness; biomarkers; genomics; prostate cancer; proteomics ID RADICAL PROSTATECTOMY; HEALTH INDEX; ANTIGEN; MEN; MULTICENTER; PCA3; SURVEILLANCE; DIAGNOSIS; BIOPSIES; UTILITY AB Purpose of reviewThis review is intended to provide an overview of the current state of biomarkers for prostate cancer (PCa), with a focus on biomarkers approved by the US Food and Drug Administration (FDA) as well as biomarkers available from Clinical Laboratory Improvement Amendment (CLIA)-certified clinical laboratories within the last 1-2 years.Recent findingsDuring the past 2 years, two biomarkers have been approved by the US FDA. These include proPSA as part of the Prostate Health Index (phi) by Beckman Coulter, Inc and PCA3 as Progensa by Gen Probe, Inc. With the advances in genomic and proteomic technologies, several new CLIA-based laboratory-developed tests have become available. Examples are Oncotype DX from Genomics Health, Inc, and Prolaris from Myriad Genetics, Inc. In most cases, these new tests are based on a combination of multiple genomic or proteomic biomarkers.SummarySeveral new tests, as discussed in this review, have become available during the last 2 years.

TI Power lines, roads, and avian nest survival: effects on predator identity and predation intensity SO ECOLOGY AND EVOLUTION LA English DT Article DE Brown-headed cowbirds; edge effects; habitat fragmentation; nest cameras; nest predation; rat snakes ID SNAKES ELAPHE-OBSOLETA; HABITAT USE; FOREST FRAGMENTATION; SUCCESS; BIRDS; LANDSCAPE; SELECTION; THERMOREGULATION; METAANALYSIS; ENVIRONMENT AB Anthropogenic alteration of landscapes can affect avian nest success by influencing the abundance, distribution, and behavior of predators. Understanding avian nest predation risk necessitates understanding how landscapes affect predator distribution and behavior. From a sample of 463 nests of 17 songbird species, we evaluated how landscape features (distance to forest edge, unpaved roads, and power lines) influenced daily nest survival. We also used video cameras to identify nest predators at 137 nest predation events and evaluated how landscape features influenced predator identity. Finally, we determined the abundance and distribution of several of the principal predators using surveys and radiotelemetry. Distance to power lines was the best predictor of predator identity: predation by brown-headed cowbirds (Molothrus ater), corvids (Corvus sp. and Cyanocitta cristata), racers (Coluber constrictor), and coachwhips (Masticophis flagellum) increased with proximity to power lines, whereas predation by rat snakes (Elaphe obsoleta) and raptors decreased. In some cases, predator density may reliably indicate nest predation risk because racers, corvids, and cowbirds frequently used power line right-of-ways. Of five bird species with enough nests to analyze individually, daily nest survival of only indigo buntings (Passerina cyanea) decreased with proximity to power lines, despite predation by most predators at our site being positively associated with power lines. For all nesting species combined, distance to unpaved road was the model that most influenced daily nest survival. This pattern is likely a consequence of rat snakes, the locally dominant nest predator (28% of predation events), rarely using power lines and associated areas. Instead, rat snakes were frequently associated with road edges, indicating that not all edges are functionally similar. Our results suggest that interactions between predators and landscape features are likely to be specific to both the local predators and landscape. Thus, predicting how anthropogenic changes to landscapes affect nesting birds requires that we know more about how landscape changes affect the behavior of nest predators and which nest predators are locally important.

TI Accelerated hematopoietic syndrome after radiation doses bridging hematopoietic (H-ARS) and gastrointestinal (GI-ARS) acute radiation syndrome: Early hematological changes and systemic inflammatory response syndrome in minipig SO INTERNATIONAL JOURNAL OF RADIATION BIOLOGY LA English DT Article DE Animal model; minipig; ARS; radiation; SIRS; blood ID GOTTINGEN MINIPIG; CITRULLINE; EXPOSURE; DAMAGE AB Purpose: To characterize acute radiation syndrome (ARS) sequelae at doses intermediate between the bone marrow (H-ARS) and full gastrointestinal (GI-ARS) syndrome. Methods: Male minipigs, approximately 5 months old, 9-12 kg in weight, were irradiated with Cobalt-60 (total body, bilateral gamma irradiation, 0.6 Gy/min). Endpoints were 10-day survival, gastrointestinal histology, plasma citrulline, bacterial translocation, vomiting, diarrhea, vital signs, systemic inflammatory response syndrome (SIRS), febrile neutropenia (FN). Results: We exposed animals to doses (2.2-5.0 Gy) above those causing H-ARS (1.6-2.0 Gy), and evaluated development of ARS. Compared to what was observed during H-ARS (historical data: Moroni et al. 2011a, 2011c), doses above 2 Gy produced signs of increasingly severe pulmonary damage, faster deterioration of clinical conditions, and faster increases in levels of C-reactive protein (CRP). In the range of 4.6-5.0 Gy, animals died by day 9-10; signs of the classic GI syndrome, as measured by diarrhea, vomiting and bacterial translocation, did not occur. At doses above 2 Gy we observed transient reduction in circulating citrulline levels, and animals exhibited earlier depletion of blood elements and faster onset of SIRS and FN. Conclusions: An accelerated hematopoietic subsyndrome (AHARS) is observed at radiation doses between those producing H-ARS and GI-ARS. It is characterized by early onset of SIRS and FN, and greater lung damage, compared to H-ARS.

To develop an infection mouse model, a mite-derived isolate of O. tsutsugamushi was established from a laboratory-maintained colony of Leptotrombidium chiangraiensis (O. tsutsugamushi Lc-1). This Lc-1 isolate was initially presented to ICR (CD-1) mice by feeding an infected Lc chigger on the ear of a mouse. Once the Lc-1 was adapted to the ICR mice, quantitative real-time polymerase chain reaction was used to investigate O. tsutsugamushi genomic equivalent copies in tissues and sera. Furthermore, times to onset of the signs of infection are reported in this study. This study provides information useful for future research on this host pathogen interaction and the associated vaccine effieacy trials.

TI Adolescent traumatic stress experience results in less robust conditioned fear and post-extinction fear cue responses in adult rats SO PHARMACOLOGY BIOCHEMISTRY AND BEHAVIOR LA English DT Article DE Adolescence; Development; Stress; Fear conditioning; Operant behavior; Conditioned suppression ID EARLY-LIFE STRESS; BASOLATERAL AMYGDALA; POTENTIATED STARTLE; UNDERWATER TRAUMA; POSTTRAUMATIC-STRESS; CHILDHOOD ADVERSITY; PAVLOVIAN FEAR; MEMORY; SUPPRESSION; JUVENILE AB Early exposure to a traumatic event may produce lasting effects throughout the lifespan. Traumatic stress during adolescence may deliver a distinct developmental insult compared with more-often studied neonatal or juvenile traumatic stress paradigms. The present study describes the lasting effects of adolescent traumatic stress upon adulthood fear conditioning. Adolescent rats were exposed to a traumatic stressor (underwater trauma, UWT), then underwent fear conditioning during adulthood. Fear extinction was tested over five conditioned suppression extinction sessions three weeks later. The efficacies of two potential extinction-enhancing compounds, endocannabinoid reuptake inhibitor AM404 (10 mg/kg) and M1 muscarinic positive allosteric modulator BQCA (10 mg/kg), were also assessed. Finally, post-extinction fear responses were examined using a fear cue (light) as a prepulse stimulus. Rats traumatically stressed during adolescence showed blunted conditioned suppression on day 1 of extinction training, and AM404 reversed this effect. Post-extinction startle testing showed that fear conditioning eliminates prepulse inhibition to the light cue. Startle potentiation was observed only in rats without adolescent UWT exposure. AM404 and BQCA both ameliorated this startle potentiation, while BQCA increased startle in the UWT group. These results suggest that exposure to a traumatic stressor during adolescence alters developmental outcomes related to stress response and fear extinction compared to rats without adolescent traumatic stress exposure, blunting the adulthood fear response and reducing residual post-extinction fear expression. Efficacy of pharmacological interventions may also vary as a factor of developmental traumatic stress exposure. (C) 2014 Elsevier Inc. All rights reserved. C1 [Moore, Nicole L.

TI Effects of Protein Supplements on Muscle Damage, Soreness and Recovery of Muscle Function and Physical Performance: A Systematic Review SO SPORTS MEDICINE LA English DT Review ID CHAIN AMINO-ACID; ENDURANCE CYCLING PERFORMANCE; FORCE ECCENTRIC EXERCISE; WELL-TRAINED MEN; RESISTANCE EXERCISE; CARBOHYDRATE-PROTEIN; SKELETAL-MUSCLE; FED STATE; DIETARY SUPPLEMENTATION; MICRORNA EXPRESSION AB Background Protein supplements are frequently consumed by athletes and recreationally-active individuals, although the decision to purchase and consume protein supplements is often based on marketing claims rather than evidence-based research. Objective To provide a systematic and comprehensive analysis of literature examining the hypothesis that protein supplements enhance recovery of muscle function and physical performance by attenuating muscle damage and soreness following a previous bout of exercise. Data Source English language articles were searched with PubMed and Google Scholar using protein and supplements together with performance, exercise, competition and muscle, alone or in combination as keywords. Study Selection Inclusion criteria required studies to recruit healthy adults less than 50 years of age and to evaluate the effects of protein supplements alone or in combination with carbohydrate on performance metrics including time-to-exhaustion, time-trial or isometric or isokinetic muscle strength and markers of muscle damage and soreness. Twenty-seven articles were identified of which 18 dealt exclusively with ingestion of protein supplements to reduce muscle damage and soreness and improve recovery of muscle function following exercise, whereas the remaining 9 articles assessed muscle damage as well as performance metrics during single or repeat bouts of exercise. Study Appraisal and synthesis Methods Papers were evaluated based on experimental design and examined for confounders that explain discrepancies between studies such as dietary control, training state of participants, sample size, direct or surrogate measures of muscle damage, and sensitivity of the performance metric. Results High quality and consistent data demonstrated there is no apparent relationship between recovery of muscle function and ratings of muscle soreness and surrogate markers of muscle damage when protein supplements are consumed prior to, during or after a bout of endurance or resistance exercise. There also appears to be insufficient experimental data demonstrating ingestion of a protein supplement following a bout of exercise attenuates muscle soreness and/or lowers markers of muscle damage. However, beneficial effects such as reduced muscle soreness and markers of muscle damage become more evident when supplemental protein is consumed after daily training sessions. Furthermore, the data suggest potential ergogenic effects associated with protein supplementation are greatest if participants are in negative nitrogen and/or energy balance. Limitations Small sample numbers and lack of dietary control limited the effectiveness of several investigations. In addition, studies did not measure the effects of protein supplementation on direct indices of muscle damage such as myofibrillar disruption and various measures of protein signaling indicative of a change in rates of protein synthesis and degradation. As a result, the interpretation of the data was often limited. Conclusion Overwhelmingly, studies have consistently demonstrated the acute benefits of protein supplementation on post-exercise muscle anabolism, which, in theory, may facilitate the recovery of muscle function and performance. However, to date, when protein supplements are provided, acute changes in post-exercise protein synthesis and anabolic intracellular signaling have not resulted in measureable reductions in muscle damage and enhanced recovery of muscle function. Limitations in study designs together with the large variability in surrogate markers of muscle damage reduced the strength of the evidence-base.

TI On the proper formulation of Maxwellian electrodynamics for continuum mechanics SO CONTINUUM MECHANICS AND THERMODYNAMICS LA English DT Article DE Convective coordinates; Continuum mechanics; Electrodynamics; Relativity theory AB Despite the importance of electromagnetomechanical physics to processes ranging from piezoelectricity to the dynamics of electron beams, confusion abounds in the continuum mechanics literature as to how Maxwell's equations of electrodynamics should be formulated in the material frame of continuum mechanics. Current formulations in the literature conflict as to the manner in which the authors define fields, derive constitutive relations, and interpret contradictory formulations. The difficulties persist even when the phenomena described are electrostatic. This paper will demonstrate that the perplexity arises from two sources: a misunderstanding of the limitations of material frame descriptions, and the failure to appreciate the centrality of relativity theory to the formulation of electrodynamic equations in the vicinity of mechanical motion. Two new formulations of Maxwell's equations are provided that avoid the paradoxes of earlier formulations and thus describe the physics clearly and without self-contradiction.

If left unrepaired, the crack could grow to reach a critical length and threaten the integrity of the structure. Although the cracks are typically characterized by stable propagation rate, the scatter in fatigue performance is difficult to quantify and could be on the order of thousands or even millions of cycles. The development of maintenance and management programs for ship structures should therefore account for the inherent scatter in performance through probabilistic fatigue assessment. Probabilistic assessment by testing a large number of specimens can be very costly. Therefore, the assessment can be performed through conducting large number of numerical or analytical simulations that account for the inherent statistical scatter in both load and resistance. This paper presents a framework for probabilistic assessment of the propagation rate of cracks in welded stiffened panels using finite element Monte Carlo simulations. The parameters influencing the propagation rate are treated as random variables with predefined statistical distributions. The results can be used for proposing inspection intervals for ships. In addition, very useful insight can be drawn on the most sensitive parameters affecting crack growth in the panels and the probability of failure at a given inspection period. (C) 2014 Elsevier Ltd.

A model predictive controller (MPC) is developed to achieve improved system performance subject to input and state constraints. The subsystem dynamic couplings and control authority limitations under thermal constraints are investigated by both static and dynamic analysis. Through judicious allocation of penalty parameters in the cost function associated with the fuel cell current, anode fuel flow rate, and generator load, several different MPC implementations are derived to explore different control design degree of freedom and their performance is evaluated. Simulation results show the efficacy of the MPC design by demonstrating the fast load transition while maintaining the stack temperature within the allowable operation limits.

TI Development of an Aotus nancymaae Model for Shigella Vaccine Immunogenicity and Efficacy Studies SO INFECTION AND IMMUNITY LA English DT Article ID 2A SOMATIC ANTIGEN; FLEXNERI 2A; RHESUS-MONKEYS; COLONIC LESIONS; ANIMAL-MODEL; CAMPYLOBACTER-JEJUNI; BACILLARY DYSENTERY; DIARRHEAL DISEASE; SUBUNIT VACCINE; INVASIN COMPLEX AB Several animal models exist to evaluate the immunogenicity and protective efficacy of candidate Shigella vaccines. The two most widely used nonprimate models for vaccine development include a murine pulmonary challenge model and a guinea pig keratoconjunctivitis model. Nonhuman primate models exhibit clinical features and gross and microscopic colonic lesions that mimic those induced in human shigellosis. Challenge models for enterotoxigenic Escherichia coli (ETEC) and Campylobacter spp. have been successfully developed with Aotus nancymaae, and the addition of a Shigella-Aotus challenge model would facilitate the testing of combination vaccines. A series of experiments were designed to identify the dose of Shigella flexneri 2a strain 2457T that induces an attack rate of 75% in the Aotus monkey. After primary challenge, the dose required to induce an attack rate of 75% was calculated to be 1 Chi 10(11) CFU. Shigella-specific immune responses were low after primary challenge and subsequently boosted upon rechallenge. However, preexisting immunity derived from the primary challenge was insufficient to protect against the homologous Shigella serotype. A successive study in A. nancymaae evaluated the ability of multiple oral immunizations with live-attenuated Shigella vaccine strain SC602 to protect against challenge. After three oral immunizations, animals were challenged with S. flexneri 2a 2457T. A 70% attack rate was demonstrated in control animals, whereas animals immunized with vaccine strain SC602 were protected from challenge (efficacy of 80%; P = 0.05). The overall study results indicate that the Shigella-Aotus nancymaae challenge model may be a valuable tool for evaluating vaccine efficacy and investigating immune correlates of protection.

The US Army Surgeon General's vision to transition from a health care system to a system of health requires the identification of key health enablers to facilitate the adoption of healthy behaviors. In support of this vision, the US Army Telemedicine add Advanced Technology Research Center hosted a workshop in April 2013 titled "Intentives to Create and Sustain Change for Health." Members of government and academia participated to identify key. health enablers that could ultimately be leveraged by technology. The key health enablers discussed included (1) public health messaging, (2) changing health habits and the environmental influence on health, (3) goal setting and tracking, (4) the role of incentives in behavior-change intervention, and (5) the role of peer and social networks on change. This. report summarizes leading evidence and the group consensus on evidence-based practices with respect to the key enablers in creating healthy behavior change.

Clinical measures associated with dynamic balance and functional movement. J Strength Cond Res 28(5): 1272-1283, 2014-Decreased balance and impaired functional movement have been linked with increased injury risk. The purpose of our study was to determine the association between specific measures of power, strength, flexibility, balance, and endurance compared with more global measures of dynamic balance, using the Y-Balance Test (YBT), and functional movement, using the functional movement screen (FMS), in healthy soldiers. Our participants (n = 64; 53 men, 11 women) were healthy active duty service members (25.2 +/- 3.8 years, 25.1 +/- 3.1 kg center dot m(-2)). Seventeen tests with 38 associated measures of strength, power, flexibility, endurance, balance, and functional measures were assessed. A significant Pearson product moment correlation (r > 0.2 and p < 0.01) was used to narrow the number of variables of interest. Two hierarchical stepwise regression analyses were performed to determine the most parsimonious set of variables associated with the YBT and FMS performance scores. Our results included a 4 variable model (F = 13.4, p < 0.001) that was associated with YBT scores (R = 0.72, R-2 = 0.51). Superior performance on the YBT was associated with better performance on the FMS lunge and upper trunk mobility tests, decreased number of hops during a 6-m hop test, and greater gastrocnemius flexibility. A second 4 variable model (F = 11.813, p < 0.001) was associated with FMS scores (R = 0.70, R-2 = 0.50). Superior performance on the FMS was associated with greater anterior reach on the YBT, greater distance on the crossover hop test, increased hamstring flexibility, and higher levels of self-reported function through the lower-extremity functional scale. Physical fitness leaders and clinicians could use these models to inform decision making when developing and assessing the outcomes of a personalized intervention program for those with low FMS and YBT scores.

Reliability and smallest worthwhile difference of the NFL-225 test in NCAA Division I football players. J Strength Cond Res 28(5): 1427-1432, 2014-The NFL-225 test is widely used to assess the strength level and evaluate the progress of college football players during resistance training. Despite the studies evaluating the validity of this test, there are no reports assessing its reliability. The purpose of this study was to determine the reliability and smallest worthwhile difference (SWD) of the NFL-225 test in Division I college football players. Seventy-two players were assessed for more than 3 weeks for the number of repetitions completed with a constant load of 102.3 kg (225 lbs) during winter conditioning. Test sessions occurred on the same day and at the same time 1 week apart. Intraclass correlation coefficients (ICCs) between weeks 1 and 2 (ICC = 0.987), weeks 2 and 3 (ICC = 0.981), and across weeks 1, 2, and 3 (ICC = 0.988) indicated high relative reliability. A small technical error (TE) (TE = 0.5 repetitions) provided strong absolute reliability. The SWD suggests that a change in performance of 3 repetitions or more after training would indicate a meaningful improvement in performance for this test. C1 [Mann, J.

TI High protein diets do not attenuate decrements in testosterone and IGF-I during energy deficit SO METABOLISM-CLINICAL AND EXPERIMENTAL LA English DT Article DE Weight loss; Anabolic hormones; Androgen ID GROWTH-FACTOR-I; RESISTANCE EXERCISE; SKELETAL-MUSCLE; PHYSICAL-ACTIVITY; BODY-COMPOSITION; BALANCE; MEN; RESPONSES; RESTRICTION; HORMONE AB Objective. Energy deficit (ED) diminishes fat-free mass (FFM) with concomitant reductions in anabolic hormone secretion. A modest increase in protein to recommended dietary allowance (RDA) levels during ED minimally attenuates decrements in insulin-like growth factor-I (IGF-I). The impact of dietary protein above the RDA on circulating anabolic hormones and their relationships with FFM in response to ED are not well described. Materials/Methods. Thirty-three adults were assigned diets providing protein at 0.8 (RDA), 1.6 (2x-RDA), and 2.4 (3x-RDA) g/kg/d for 31 days. Testosterone, sex-hormone binding globulin (SHBG) and IGF-I system components were assessed after a 10-day period of weight-maintenance (VIM) and after a 21-day period of ED (40%) achieved by an increase in energy expenditure and decreased energy intake. Associations between the change in FFM and anabolic hormone levels were determined. Results. As compared to WM and regardless of dietary protein intake, total and free testosterone, total IGF-I, and acid-labile subunit decreased (P < 0.05), whereas SHBG and IGF binding proteins-1, -2, and -3 increased (P < 0.05) during ED. There were no energy-by-protein interactions on any hormones or IGF-I system components measured. Changes in FFM in response to ED were negatively associated with acid-labile subunit (ALS) (r = -0.62, P < 0.05) in 2x-RDA; however, no other relationships were observed. Conclusion. Consuming a high protein diet does not impact the androgenic and IGF-I system response to ED. These data suggest that the protective effects of high protein diets on FFM during ED are likely not influenced by anabolic hormone concentrations. Published by Elsevier Inc.

These complex injuries require advanced methods of reconstruction, involving prolonged ischemic periods and reperfusion injury. Using our group's validated porcine model of gracilis myocutaneous flap transplantation, this study demonstrates that an interim perfusion of hydrogen sulfide (H2S) mitigates the effects of reperfusion injury in the setting of delayed restoration of blood flow. Methods A gracilis myocutaneous flap (200-400 g; surface area, 250 cm(2)) was procured from the hind limb of a Yorkshire swine (70-90 kg, n = 16). The right external carotid artery and the internal jugular vein are the recipient axis. Group 1 (control, n = 6) underwent delayed anastomosis with a 3-hour ischemic period. Group 2 (n = 10) underwent a similar delayed anastomosis with an interim perfusion of H2S during the ischemic period. The animals survived for 14 days. Systemic biomarker assays for skeletal muscle tissue injury (creatine kinase, lactate dehydrogenase, and aspartate transaminase) and proinflammatory markers (tumor necrosis factor alpha and interleukin 6) provide assessment of reperfusion injury at the cellular level. Results The control animals (3 hours of ischemia with an interim perfusion of heparinized saline) demonstrated increased levels of injury biomarkers and proinflammatory cytokines compared with the animals receiving H2S infusion and identical ischemic interval. The control flaps had a mean creatine kinase level of 280 x 10(3) U/L (+/- 80 x 10(3)), compared with the H2S group, which had a mean of 99 x 10(3) U/L (+/- 14 x 10(3); P = 0.0007 at postoperative day 2). lactate dehydrogenase levels (mean) were 26 x 10(3) U/L (+/- 8 x 10(3)) versus 9 x 10(3) U/L (+/- 3 x 10(3); P = 0.0004) and aspartate transaminase levels (mean) were 1651 U/L (+/- 324) versus (873 U/L [+/- 279]; P = 0.0013) for the control and treatment groups, respectively. Similarly, an intergroup difference in IL-6 was found, although not statistically significant. Tumor necrosis factor alpha levels (mean) were 93 pg/mL (+/- 14) versus 39 pg/mL (+/- 4; P = 0.0013) for the control and treatment groups, respectively. Conclusions This study demonstrated the mitigating properties of H2S on reperfusion injury. Interim perfusion with H2S resulted in diminution of ischemia-dependent biomarkers after 3 hours of ischemia. Follow-up studies will translate these findings as an evolving method for reconstructing previously unreconstructable injuries.

Early detection of fatigue-related performance decrements is an important component of injury prevention and can help to ensure optimal performance and mission readiness. This study used a predictive visual tracking task and a computer-based measure of attention to characterize fatigue-related attention decrements in healthy Army personnel during acute sleep deprivation. Methods: Serving as subjects in this laboratory-based study were 87 male and female service members between the ages of 18 and 50 with no history of brain injury with loss of consciousness, substance abuse, or significant psychiatric or neurologic diagnoses. Subjects underwent 26 h of sleep deprivation, during which eye movement measures from a continuous circular visual tracking task and attention measures (reaction time, accuracy) from the Attention Network Test (ANT) were collected at baseline, 20 h awake, and between 24 to 26 h awake. Results: Increases in the variability of gaze positional errors (46-47%), as well as reaction time-based ANT measures (9-65%), were observed across 26 h of sleep deprivation. Accuracy of ANT responses declined across this same period (11%). Discussion: Performance measures of predictive visual tracking accurately reflect impaired attention due to acute sleep deprivation and provide a promising approach for assessing readiness in personnel serving in diverse occupational areas, including flight and ground support crews.

TI Mission, Physical, and War Stressors' Impact on Aircrew Psychological Strain SO AVIATION SPACE AND ENVIRONMENTAL MEDICINE LA English DT Article DE work stress; well-being; sleep; PTSD; depression; nervousness ID PHQ-9 AB Background: Little is known about the relative impact of the organization of missions on aircrew well-being. Using an occupational stress model we investigate a previously little studied concept of mission stressors and determine its relative impact in comparison to physical and war stressors in the prediction of four strains in deployed aircrews. Method: Questionnaires were completed by 272 deployed in-aircraft crewmembers. Three new stressors were developed for this study: mission stressors, physical stressors, and war stressors. In addition, four strains were measured: PTSD, depression, sleepiness, and nervousness. Regression analyses were used to examine the relative impact of each stressor on the four strain measures while controlling for age and occupation. Results: All three stressors played a significant role in the prediction strains with the total explained variance in the analyses ranging from 15% and 39%. Interestingly, mission stressors played the most important role in the prediction of strains possessing the largest partial eta squared in each analysis. The second most important stressor was physical stressors followed by war stressors. Conclusion: The importance of mission stressors may be because current training is designed to inoculate crewmembers to stressors such as the physical/environmental conditions and violentwar actions, but there is no training or acknowledgment of the importance of dealing with mission stressors. Our findings suggest it might be beneficial for commanders to address these stressors, as it may improve short-term psychological well-being, which may ultimately impact mission success and safety.

TI Enhancement of on-chip combustion via nanoporous silicon microchannels SO COMBUSTION AND FLAME LA English DT Article DE Porous silicon; Energetic materials; Microstructure; Acoustic initiation ID POROUS SILICON; INFRARED-SPECTROSCOPY; HYDROGEN TERMINATION; SURFACE-MORPHOLOGY; EXPLOSIVE DEVICES; HF TREATMENT; DETONATION; THERMITE; SI(111) AB Due to its high energy density and MEMS compatible fabrication methods, on-chip porous silicon shows considerable promise as an energetic material. Rapid combustion events have been demonstrated with flame propagation speeds eclipsing 3 km/s, but much is still unknown about the controlling parameters of porous silicon combustion. Recent studies show that implementation of microstructure within a nanoporous silicon film greatly increases reaction rate of a relatively slow burning system. The present work utilizes porous silicon microchannels to enhance an already rapidly-reacting system. Reactions in channeled porous silicon regions of this system propagated at speeds up to 1.2 km/s faster than similar neat porous silicon films. The fastest propagation speed was 3660 m/s, the highest reported flame speed for comparable nanoenergetic systems to date. We provide evidence that the enhancement of flame propagation rates by channeled porous silicon is mechanistically different from the convectively controlled burning of neat porous silicon. This evidence suggests the presence of acoustically aided reactions for porous silicon channel combustion where the channels more readily ignite compared to neat porous silicon. We predict this allows for propagation of the reaction by intense sound waves within the porous medium. (C) 2013 The Combustion Institute. Published by Elsevier Inc. All rights reserved.

TI Oxidation and mobilization of metallic antimony in aqueous systems with simulated groundwater SO GEOCHIMICA ET COSMOCHIMICA ACTA LA English DT Article ID RAY-DIFFRACTION PATTERNS; QUANTITATIVE INTERPRETATION; HYDROGEN-PEROXIDE; NONTRONITE NAU-1; SHOOTING RANGES; HEAVY-METALS; HUMIC-ACID; SORPTION; SB(III); ENVIRONMENT AB Antimony (Sb) is a contaminant of concern that can be present in elevated concentrations in shooting range soils due to mobilization from spent lead/antimony bullets. Antimony in shooting range soils has been observed as either metallic Sb(0) or as Sb(V) immobilized by iron (hydr)oxides. The absence of Sb(III) in soils is indicative of rapid Sb(III) oxidation to Sb(V) under surface soil conditions. However, the major controls on antimony oxidation and mobility are poorly understood. To better understand these controls we performed multiple batch experiments under oxic conditions to quantify the oxidation and dissolution of antimony in systems where Sb(0) is oxidized to Sb(III) and further to Sb(V). We also tested how variations in the aqueous matrix composition and the presence of metallic lead (Pb) affect the dissolution, solid phase speciation, and oxidation of antimony. We monitored changes in the aqueous antimony speciation using liquid chromatography inductively coupled plasma mass spectrometry (LC-ICP-MS). To test which solid phases form as a result of Sb(0) oxidation, and therefore potentially limit the mobility of antimony in our studied systems, we characterized the partially oxidized Sb(0) powders by means of extended X-ray absorption fine structure (EXAFS) spectroscopy and powder X-ray diffraction (XRD). The observed oxidation of Sb(0) to Sb(III) and mobilization to solution is rapid: after 5-15 min of reaction the aqueous antimony concentration reached 50-600 mu M. The amount of dissolved antimony and the rate of Sb(III) oxidation to Sb(V) in deionized water is lower than what we measured in the simulated groundwater systems. Senarmontite (Sb2O3), the primary crystalline oxidation product of Sb(0), was detected after one month from the beginning of Sb(0) oxidation. The maximum aqueous Sb(III) concentration is about 30 times larger than the predicted equilibrium concentration with respect to senarmontite in the initial stages (<65 h) of our experiment. Concentrations reach equilibrium within 146-222 days. The maximum concentration of Sb(V) is controlled by cation availability for the precipitation of an antimonate. In the systems where sodium Na(I) exceeded 20 mM precipitation of mopungite is observed. No crystalline phases were detected in the systems with added lead, and the dissolved Sb(V) concentration is several orders of magnitude higher than would be expected in equilibrium with bindheimite (Pb2Sb2O7). The observed solubility of Sb(V) in the systems with Ca(II) is several orders of magnitude larger than the solubility reported for romeite (Ca2Sb2O7). The addition of Pb(0) lowered the extent of Sb(0) oxidation due to competitive oxidation or to the coupling of antimony and lead redox reactions. The results from our research can be used to identify substrates that promote precipitation of relatively insoluble antimony compounds in target berm soils and thus prevent the offsite migration of antimony from shooting range target berms.

In this paper, we design and validate a dynamic trust management protocol for secure routing optimization in DTN environments in the presence of well-behaved, selfish and malicious nodes. We develop a novel model-based methodology for the analysis of our trust protocol and validate it via extensive simulation. Moreover, we address dynamic trust management, i.e., determining and applying the best operational settings at runtime in response to dynamically changing network conditions to minimize trust bias and to maximize the routing application performance. We perform a comparative analysis of our proposed routing protocol against Bayesian trust-based and non-trust based (PROPHET and epidemic) routing protocols. The results demonstrate that our protocol is able to deal with selfish behaviors and is resilient against trust-related attacks. Furthermore, our trust-based routing protocol can effectively trade off message overhead and message delay for a significant gain in delivery ratio. Our trust-based routing protocol operating under identified best settings outperforms Bayesian trust-based routing and PROPHET, and approaches the ideal performance of epidemic routing in delivery ratio and message delay without incurring high message or protocol maintenance overhead.

Klosky, J. Ledlie Katalenich, Scott TI Conceptual Models for Infrastructure Leadership SO JOURNAL OF MANAGEMENT IN ENGINEERING LA English DT Article DE Leadership; Infrastructure; Conceptual models AB In policy and aspirational documents both the American Society of Civil Engineers and the National Academy of Engineering have called for engineers of the 21st century to take a leading role in infrastructure discussions about and decisions. These discussions and decisions routinely involve stakeholders, constituencies, and organizations that are unfamiliar with traditional engineering modeling and analysis techniques; removing communication barriers is essential, but many find our engineering tools, methods, and explanations difficult to comprehend. Assuming a leadership role in these conversations requires engineers to adopt new conceptual models that enhance communication between people with dissimilar backgrounds and promote shared understanding. The West Point infrastructure models introduced in this paper provide engineers, decision makers, and members of society with a universal framework for understanding, visualizing, assessing, and describing complex infrastructure systems in a manner that facilitates communication, fosters participation in infrastructure decisions, and allows broad-based engagement with design processes. The Conceptual Model provides a basis for identifying, visualizing, and understanding the elements of an infrastructure, the functions they perform, and their relationships to each other. The Assessment Model consists of six prompts, which guide the formulation of focused assessment questions that consider the performance of systems and components, identified in the Conceptual Model, under both normal and adverse circumstances. The Resilience Model provides a framework for the design of resilient infrastructures that incorporates risk management, engineering design, emergency response, and rationally sequenced recovery. Conceptual models are essential tools for leaders seeking to effectively engage stakeholders in complex decision-making processes by building toward advancing a shared understanding; the models proposed in this paper are an effective tool in that role, and their adoption and use would facilitate deeper engagement by the public, and, ultimately, wiser societal decisions about infrastructure.

We investigated how fire influences exotic woody invasion through its effects on granivore activity, and whether these effects depend on the habitat in which seed predation takes place. We quantified seed removal for four species of exotic woody plants (Albizia julibrissin, Elaeagnus umbellata, Melia azedarach and Triadica sebifera) in 17 sites in longleaf pine savanna that varied in time since fire (one or three growing seasons post-fire) in the sandhills region of North Carolina, USA. Within each site, we established paired plots in upland and upland-wetland ecotone communities and presented seeds in depots that allowed either arthropod, or arthropod and small vertebrate access. We found that differences in seed removal with time since fire were contingent on habitat and granivore community. In ecotones, three of four species had higher proportions of seeds removed from plots that were three growing seasons post-fire than plots one growing season post-fire, whereas only T. sebifera showed this pattern in upland habitat. Allowing vertebrate granivores access to seeds enhanced seed removal, and this effect was strongest in ecotone habitat. While granivores removed seeds of all four plant species, removal of E. umbellata was significantly higher than that of the other species, suggesting that granivores exhibited seed selection. These findings suggest that ecotone habitats in this system experience greater seed removal than upland habitats, particularly as time since fire increases, and differences are mainly due to the activity of vertebrate granivores. Such differences in seed removal, together with seed selection, may contribute to variation in exotic woody invasion of longleaf pine savannas.

(Gama) TI Progressive damage modeling of plain weave E-glass/phenolic composites SO COMPOSITES PART B-ENGINEERING LA English DT Article DE Glass fibers; Finite element analysis (FEA); Damage tolerance; Ballistic limit AB An optimized set of material properties and parameters for E-glass/phenolic composites is determined for use in the rate dependent composite damage model MAT162 in LS-DYNA. The model requires 39 material properties and parameters, and is able to capture the seven different damage modes and post damage softening behavior of composites. The unknown MAT162 parameters were determined by conducting parametric simulations of low velocity impact (LVI), depth of penetration (DOP), and ballistic impacts. The modulus reduction parameter OMGMX is found by simulating LVI tests and varying the values of OMGMX to find the best agreement with LVI experimental data. The limit of compressive volume strain for element eroding was found by simulating DOP experiments and comparing the results to the experimental data. Then the element eroding axial strain E_LIMT and EEXPN were determined by simulating ballistic impact experiments. When the optimized values were determined, analysis of ballistic experiments were conducted and compared to the experimental impact versus residual velocity curve. The results of the simulations were in excellent agreement with the experimental data. Published by Elsevier Ltd.

This study consisted of more than 8,000 individuals in each arm of the trial, representing the four major regions of Thailand. Human leukocyte antigen (HLA) class I and killer cell immunoglobulin-like receptor (KIR) genes, as well as 96 genome-wide ancestry informative markers (AIMs) were genotyped in 450 placebo HIV-1-uninfected individuals to identify the immunogenetic diversity and population structure of this cohort. High-resolution genotyping identified the common HLA alleles as A*02:03, A*02:07, A*11:01, A*24:02, A*24:07, A*33:03, B*13:01, B*15:02, B*18:01, B*40:01, B*44:03, B*46:01, B*58:01, C*01:02, C*03:02, C*03:04, C*07:01, C*07:02, C*07:04, and C*08:01. The most frequent three-loci haplotype was B*46:01-C*01:02-A*02:07. Framework genes KIR2DL4, 3DL2, and 3DL3 were present in all samples, and KIR2DL1, 2DL3, 3DL1, 2DS4, and 2DP1 occurred at frequencies greater than 90 %. The combined HLA and KIR profile suggests admixture with neighboring Asian populations. Principal component and correspondence analyses comparing the RV144 samples to the phase 3 International HapMap Project (HapMap3) populations using AIMs corroborated these findings. Structure analyses identified a distinct profile in the Thai population that did not match the Asian or other HapMap3 samples. This shows genetic variability unique to Thais in RV144, making it essential to take into account population stratification while performing genetic association studies. The overall analyses from all three genetic markers indicate that the RV144 samples are representative of the Thai population. This will inform subsequent host genetic analyses in the RV144 cohort and provide insight for future genetic association studies in the Thai population.

TI Position Estimation for Projectiles Using Low-Cost Sensors and Flight Dynamics SO JOURNAL OF AEROSPACE ENGINEERING LA English DT Article DE Precision projectiles; Point mass model; Flight dynamics; and control; Loosely coupled global positioning system/inertial navigation system (GPS/INS); Microelectromechanical system sensors; Guidance; State estimation; Extended Kalman filter (EKF); navigation ID NAVIGATION; GUIDANCE; SYSTEM AB Navigation of gun-launched precision munitions using affordable technologies is investigated. Estimation algorithms were developed to blend flight dynamic models with measurements from inertial sensors. The launch and flight characteristics of the unique, gun-launched environment were exploited both in the state estimator and for novel heuristic parameter identification. Using the heuristic parameter, the inertial navigation system was calibrated without a global positioning system (GPS), and its performance was compared with a similar calibration performed with a GPS. The experimental results from guided mortar flights indicate that the algorithm with only inertial sensor measurements yields position errors of less than 40 m over a 30-s flight. Trade studies were conducted in simulation to assess algorithm performance over a wider range of conditions such as variation in the flight dynamic model parameters. These results demonstrate that position errors are less than tens of meters for flight times of interest to munitions. Estimation is tolerant to inertial sensor errors because of the novel manner in which known flight dynamics are used to compensate measurements. Overall, this effort shows that navigation error resulting from a low-throughput algorithm using affordable inertial sensors is sufficient to increase system accuracy for munitions in GPS-denied environments.

TI A Host-Oriented Inhibitor of Junin Argentine Hemorrhagic Fever Virus Egress SO JOURNAL OF VIROLOGY LA English DT Article ID TSG101 UEV DOMAIN; FINGER PROTEIN-Z; ARENAVIRUS INFECTIONS; ANTIVIRAL STRATEGIES; LASSA VIRUS; EBOLA; THERAPY; MOTIFS; ESCRT; VP40 AB There are currently no U. S. Food and Drug Administration (FDA)-approved vaccines or therapeutics to prevent or treat Argentine hemorrhagic fever (AHF). The causative agent of AHF is Junin virus (JUNV); a New World arenavirus classified as a National Institute of Allergy and Infectious Disease/Centers for Disease Control and Prevention category A priority pathogen. The PTAP late (L) domain motif within JUNV Z protein facilitates virion egress and transmission by recruiting host Tsg101 and other ESCRT complex proteins to promote scission of the virus particle from the plasma membrane. Here, we describe a novel compound (compound 0013) that blocks the JUNV Z-Tsg101 interaction and inhibits budding of virus-like particles (VLPs) driven by ectopic expression of the Z protein and live-attenuated JUNV Candid-1 strain in cell culture. Since inhibition of the PTAP-Tsg101 interaction inhibits JUNV egress, compound 0013 serves as a prototype therapeutic that could reduce virus dissemination and disease progression in infected individuals. Moreover, since PTAP L-domain-mediated Tsg101 recruitment is utilized by other RNA virus pathogens (e.g., Ebola virus and HIV-1), PTAP inhibitors such as compound 0013 have the potential to function as potent broad-spectrum, host-oriented antiviral drugs.

TI Composite Risk Assessment for the Sacramento-San Joaquin Delta Levee System SO JOURNAL OF WATER RESOURCES PLANNING AND MANAGEMENT LA English DT Article DE Risk; San Joaquin River; Levee; Sacramento River; Flooding; California AB The objectives of this project were to analyze available Sacramento-San Joaquin Delta, California, levee risk information in a Composite Risk Management matrix and examine the results for management decision support. U.S. Army Corps of Engineers (USACE) guidance documents define risk as the "probability and severity of loss linked to hazards" and prescribe a composite risk assessment method. The Delta Risk Management Strategy performed for a group of state and federal partners provided analyses of the relative probability of hazards and severity of risks in the Delta and provide the information needed for a risk analysis compliant with USACE requirements. Composite Risk assessment provides rank-ordered lists of the highest risk zones-those with the greatest probability of failure combined with the most severe consequences-for several hundred protected areas in the Delta. Although uncertainties in the absolute magnitude of the results make them most useful for comparisons, the actual values of the probabilities and consequences are alarming. For example, Sargent Barnhart Tract, northwest of Stockton, has a mean annual failure rate of 0.07, or an expected levee failure every 14years, with a probable 96 fatalities for a nighttime seismic-induced failure. Adjacent tracts with only slightly lower failure probabilities put another 500 lives at risk. An area of the Suisun Marsh has a projected failure rate of 0.5, or once every two years, with maximum possible damages exceeding $250million. The Sacramento Pocket Area, with a mean annual failure rate of 0.006, has over $9billion at risk. Although refinements to these risk estimates are possible, this paper and the Delta Risk Management Strategy analyses provide more than sufficient evidence that flooding in the Sacramento-San Joaquin Delta presents significant risks to California and the nation. Hundreds of lives and billions of dollar damages are at risk. Urgent action is necessary to manage those risks. C1 [McAnally, William H.] Dynam Solut LLC, Columbus, MS 39705 USA.

TI Application of TREECS Modeling System to Strontium-90 for Borschi Watershed near Chernobyl, Ukraine SO JOURNAL OF ENVIRONMENTAL RADIOACTIVITY LA English DT Article DE TREECS; Sr-90; Chernobyl; Borschi; Radioactive modeling; Contaminant fate and transport ID RADIONUCLIDES; TRANSPORT; SOIL; STREAM; AREA; RDX AB The Training Range Environmental Evaluation and Characterization System (TREECS (TM)) (http://el.erdc.usace.army.mil/treecs/) is being developed by the U.S. Army Engineer Research and Development Center (ERDC) for the U.S. Army to forecast the fate of munitions constituents (MC) (such as high explosives (HE) and metals) found on firing/training ranges, as well as those subsequently transported to surface water and groundwater. The overall purpose of TREECS (TM) is to provide environmental specialists with tools to assess the potential for MC migration into surface water and groundwater systems and to assess range management strategies to ensure protection of human health and the environment. The multimedia fate/transport models within TREECS (TM) are mathematical models of reduced form (e.g., reduced dimensionality) that allow rapid application with less input data requirements compared with more complicated models. Although TREECS (TM) was developed for the fate of MC from military ranges, it has general applicability to many other situations requiring prediction of contaminant (including radionuclide) fate in multi-media environmental systems. TREECS (TM) was applied to the Borschi watershed near the Chernobyl Nuclear Power Plant, Ukraine. At this site. TREECS (TM) demonstrated its use as a modeling tool to predict the fate of strontium 90 (Sr-90). The most sensitive and uncertain input for this application was the soil-water partitioning distribution coefficient (Kd) for Sr-90. The TREECS (TM) soil model provided reasonable estimates of the surface water export flux of Sr-90 from the Borschi watershed when using a Kd for Sr-90 of 200 L/kg. The computed export for the year 2000 was 0.18% of the watershed inventory of Sr-90 compared to the estimated export flux of 0.14% based on field data collected during 1999-2001. The model indicated that assumptions regarding the form of the inventory, whether dissolved or in solid phase form, did not appreciably affect export rates. Also, the percentage of non-exchangeable adsorbed Sr-90, which is uncertain and affects the amount of Sr-90 available for export, was fixed at 20% based on field data measurements. A Monte Carlo uncertainty analysis was conducted treating Kd as an uncertain input variable with a range of 100-300 L/kg. This analysis resulted in a range of 0.13-0.27% of inventory exported to surface water compared to 0.14% based on measured field data. Based on this model application, it was concluded that the export of Sr-90 from the Borschi watershed to surface water is predominantly a result of soil pore water containing dissolved Sr-90 being diverted to surface waters that eventually flow out of the watershed. The percentage of non-exchangeable adsorbed Sr-90 and the soil-water K-d are the two most sensitive and uncertain factors affecting the amount of export. The 200-year projections of the model showed an exponential decline in Sr-90 export fluxes from the watershed that should drop by a factor of 10 by the year 2100. This presentation will focus on TREECS capabilities and the case study done for the Borschi Watershed. Published by Elsevier Ltd.

The objectives of this study were to evaluate the ability of freshly isolated bone marrow cells to home to injured skeletal muscle and to determine their effects on muscle regeneration. Materials and methods: Freshly isolated lineage-depleted bone marrow cells (Lin(-) BMCs) were injected intravenously 2 d after I/R. Bioluminescent imaging was used to evaluate cell localization for up to 28 d after injury. Muscle function, the percentage of fibers with centrally located nuclei, and the capillary-to-fiber ratio were evaluated 14 d after delivery of either saline (Saline) or saline containing Lin(-) BMCs (Lin(-) BMCs). Results: Bioluminescence was higher in the injured leg than the contralateral control leg for up to 7 d after injection (P < 0.05) suggestive of cell homing to the injured skeletal muscle. Fourteen days after injury, there was a significant improvement in maximal tetanic torque (40% versus 22% deficit; P < 0.05), a faster rate of force production (+dP/dt) (123.6 versus 94.5 Nmm/S; P < 0.05), and a reduction in the percentage of fibers containing centrally located nuclei (40 versus 17%; P < 0.05), but no change in the capillary-to-fiber ratio in the Lin(-) BMC as compared with the Saline group. Conclusions: The homing of freshly isolated BMCs to injured skeletal muscle after I/R is associated with an increase in functional outcomes. Published by Elsevier Inc.

Background: Burned patients are admitted to specialty Burn Centers where highly complex nursing care is provided. Successful orientation and integration into such a specialized work environment is a fundamental component of a nurse's ability to provide safe and holistic patient care. Design: A systematic review of the literature was performed for the period 1995-2011 using electronic databases within PUBMED and Ovid search engines. Data sources: Databases included Medline, CINHAL, ProQuest for Dissertations and Thesis, and Cochran Collaboration using key search terms: preceptor, preceptee, preceptorship, precept*, nurs*, critical care, personality types, competency-based education, and learning styles. Review methods: Nurses graded the level and quality of evidence of the included articles using a modified 7-level rating system and the Johns Hopkins Nursing Quality of Evidence Appraisal during journal-club meetings. Results: A total of 43 articles related to competency (n = 8), knowledge acquisition and personality characteristics (n = 8), learning style (n = 5), preceptor development (n = 7), and Precepting Programs (n = 14). Conclusions: A significant clinical gap existed between the scientific evidence and actual precepting practice of experienced nurses at the Burn Center. Based on this extensive review of the literature, it was determined that a sufficient evidence base existed for development of an evidence-based Precepting Program. (C) 2013 Elsevier Ltd and ISBI.

We developed candidate DNA vaccines for HFRS expressing the Gn and Gc genes of HTNV or PUUV and evaluated them in an open-label, single-centre Phase 1 study. Three groups of nine participants each were vaccinated on days 0, 28 and 56 with the DNA vaccines for HTNV, PUUV, or a mixture of both vaccines using the Ichor Medical Systems TriGrid (TM) Intramuscular Delivery System. All vaccinations consisted of a total dose of 2.0mg DNA in an injected volume of 1mL saline. For the combined vaccine, the mixture contained equal amounts (1.0mg) of each DNA vaccine. There were no study-related serious adverse events. Neutralizing antibody responses were measured by a plaque reduction neutralization test. Neutralizing antibody responses were detected in five of nine and seven of nine individuals who completed all three vaccinations with the HTNV or PUUV DNA vaccines, respectively. In the combined vaccine group, seven of the nine volunteers receiving all three vaccinations developed neutralizing antibodies to PUUV. The three strongest responders to the PUUV vaccine also had strong neutralizing antibody responses to HTNV. These results demonstrate that the HTNV and PUUV DNA vaccines delivered by electroporation separately or as a mixture are safe. In addition, both vaccines were immunogenic, although when mixed together, more participants responded to the PUUV than to the HTNV DNA vaccine. C1 [Hooper, J.

These decision makers are increasingly informed by systems models. Diverse audiences for environmental science and sustainability policies magnify the importance of clear model communication. This essay offers a summary of best communication practices for situations in which bridging modelers' and non-modelers' conceptions of a given system their respective mental models is a principal challenge. Synthesizing social research from technical communication, educational psychology, and science communication disciplines, we discuss common areas of confusion in comprehending and explaining complex information, and present strategies model developers can use to ensure their model presentations are understandable and meaningful to audiences. We argue that accessible and socially adoptable explanations benefit from modelers listening to target audiences and anticipating how and why audiences may fail to understand aspects of a model.

To test the hypothesis that cell-seeded HA scaffolds improve bone regeneration, HA scaffolds without cell seeding (HA-empty), HA scaffolds with 1.5 x 10(4) BMSCs (HA-low), and HA scaffolds with 1.5 x 10(6) BMSCs (HA-high) were implanted in a 10-mm rabbit radius segmental defect model for 4 and 8 weeks. Three different fluorochromes were administered at 2, 4, and 6 weeks after implantation to identify differences in temporal bone growth patterns. It was observed from fluorescence histomorphometry analyses that an increased rate of bone infiltration occurred from 0 to 2 weeks (p < 0.05) of implantation for the HA-high group (2.9 +/- 0.5 mm) as compared with HA-empty (1.8 +/- 0.8 mm) and HA-low (1.3 +/- 0.2 mm) groups. No significant differences in bone formation within the scaffold or callus formation was observed between all groups after 4 weeks, with a significant increase in bone regenerated for all groups from 4 to 8 weeks (28.4% across groups). Although there was no difference in bone formation within scaffolds, callus formation was significantly higher in HA-empty scaffolds (100.9 +/- 14.1 mm(3)) when compared with HA-low (57.8 +/- 7.3 mm(3); p <= 0.003) and HA-high (69.2 +/- 10.4 mm(3); p <= 0.02) after 8 weeks. These data highlight the need for a better understanding of the parameters critical to the success of cell-seeded HA scaffolds for bone regeneration. (c) 2013 Wiley Periodicals, Inc.

TI Effects of hyaluronic acid conjugation on anti-TNF-alpha inhibition of inflammation in burns SO JOURNAL OF BIOMEDICAL MATERIALS RESEARCH PART A LA English DT Article DE TNF-alpha; burn wound, inflammation; hyaluronic acid; wound healing ID NECROSIS-FACTOR-ALPHA; EXPRESSION; PROGRESSION; MACROPHAGE; MOLECULES; RABBIT; WOUNDS; CELLS; RATS; TIME AB Biomaterials capable of neutralizing specific cytokines could form the basis for treating a broad range of conditions characterized by intense, local inflammation. Severe burns, spanning partial- to full-thickness of the dermis, can result in complications due to acute inflammation that contributes to burn progression, and early mediation may be a key factor in rescuing thermally injured tissue from secondary necrosis to improve healing outcomes. In this work, we examined the effects on burn progression and influence on the inflammatory microenvironment of topical application of anti-tumor necrosis factor-alpha (anti-TNF-alpha) alone, mixed with hyaluronic acid (HA) or conjugated to HA. We found that non-conjugated anti-TNF-alpha decreased macrophage infiltration to a greater extent than that conjugated to HA; however, there was little effect on the degree of progression or IL-1 beta levels. A simple transport model is proposed to analyze the results, which predicts qualitative and quantitative differences between untreated burn sites and those treated with the conjugates. Our results indicate that conjugation of anti-TNF-alpha to high molecular weight HA provides sustained, local modulation of the post-injury inflammatory responses compared to direct administration of non-conjugated antibodies.

A substantial, albeit suboptimal, effort has been made to define diagnostic criteria for mTBI and improve diagnostic accuracy. Thus, biomarkers that can accurately and objectively detect brain injury after mTBI and, ideally, aid in clinical management are needed. In this review, we discuss the current research on serum biomarkers for mTBI including their rationale and diagnostic performances. Sensitive and specific biomarkers reflecting brain injury can provide important information regarding TBI pathophysiology and serve as candidate markers for predicting abnormal computed tomography findings and/or the development of residual deficits in patients who sustain an mTBI. We also outline the roles of biomarkers in settings of specific interest including pediatric TBI, sports concussions and military injuries, and provide perspectives on the validation of such markers for use in the clinic. Finally, emerging proteomics-based strategies for identifying novel markers will be discussed. C1 [Mondello, Stefania] Univ Messina, Dept Neurosci, I-98125 Messina, Italy.

By calculating the stability of the liquid phase at low temperatures, this method could be a useful and cost-effective tool for the design of bulk metallic glasses. Based on the thermodynamic modeling of the constituent binary and ternary systems of W with Fe, Hf, Pd, Ta, Si, or C, thermodynamic databases are built to search for W-based metallic glasses in these alloying systems. Modeling of intermetallic phases combines input from first-principles total energy calculations and predictions of finite temperature properties from the Debye-Grfineisen model. Several plausible W-rich glass-forming alloys are identified in the W-Fe-Si-C quaternary system. (C) 2013 Elsevier Ltd. All rights reserved. C1 [Hu, Y. J.; Lieser, A. C.; Saengdeejing, A.; Liu, Z.

TI Three-Dimensional Mass Fraction Distribution of a Spray Measured by X-Ray Computed Tomography SO JOURNAL OF ENGINEERING FOR GAS TURBINES AND POWER-TRANSACTIONS OF THE ASME LA English DT Article ID FUEL SPRAYS; RADIOGRAPHY; MECHANICS AB In order to design a spraying system with the desired characteristics, the atomization process has to be understood in detail, including the primary breakup of the liquid core. Accurate prediction of primary breakup is a major barrier to computer-based analysis of spray combustion. The development of models is hindered by the lack of validation data in a region where the fluid is dense, and optical access is therefore limited. The present experimental study is aimed at probing the spray structure by means of X-ray computed tomography (CT). A full-cone atomizer (0.79 mm orifice diameter) spraying in air at ambient pressure is investigated as a proof of concept. A mixture of water and iodine is used as the working fluid, providing elevated X-ray absorption and therefore, improved signal-to-noise ratio. Several hundreds of X-ray projections are acquired as the spraying atomizer is rotated in front of the detector. Standard software for medical imaging is used to reconstruct the three-dimensional time-averaged distribution of liquid mass fraction in the full field of view, from the intact liquid core to the dilute spray region. A spatial resolution of 0.6 mm is obtained along the spraying direction, while the resolution is 0.3 mm in the other two directions. Significant asymmetries in the structure of the spray are revealed. C1 [Coletti, Filippo; Eaton, John K.] Stanford Univ, Dept Mech Engn, Stanford, CA 94305 USA.

Participants were grouped into one of three categories on the basis of clinical norm criteria: PTSD only, HSU only, and PTSD + HSU. Participants completed the PTSD Checklist-Military, Experiences in Close Relationships Scale-Short Form, Center for Epidemiologic Studies-Depression scale, Alcohol Use Disorders Identification Test, Drug Use Disorders Identification Test, and Psychological Aggression and Physical Violence subscales of the Conflict Tactics Scale. Most participants were male and Caucasian. Significant differences were found between groups on depression, avoidant attachment, psychological aggression perpetration and victimization, and physical violence perpetration and victimization. Post hoc analyses revealed that the PTSD + HSU group had significantly higher levels of depression, avoidant attachment, and psychological aggression than the HSU only group. The PTSD + HSU group had significantly higher levels of physical violence than did the PTSD only group, but both groups had similar mean scores on all other variables.

Recently, characterization of a 1200-V, 800-A all-SiC dual module designed for large-scale electric military vehicle applications has been reported. This paper expands on the previous work by presenting details and results obtained from a long-term evaluation of a similar module. The module has successfully operated in an experimental circuit at a switching frequency of 10 kHz while running vehicle load profiles for over 1000 h and exhibited little change in device characteristics. Of all measured characteristics, none had a significant unfavorable change greater than 10% from its initial value. The 1000 h of circuit operation represents 11 783 miles of use or over half of the expected lifecycle in a military vehicle traction inverter.

In addition, placing graphene within the defect layer of an asymmetric, one-dimensional photonic crystal triggers nearly 100% narrowband absorption. We demonstrate that the improved field localization within the defect state enhances third-harmonic generation by nearly five orders of magnitude compared with bare monolayer graphene. Saturation of the third-order susceptibility plays a role at both fundamental and third-harmonic frequencies. We discuss the benefits of including graphene within the structure for both signals.

Unmixing algorithms are derived from an objective function. The objective function incorporates the linear mixture model for macroscopic unmixing and a nonlinear mixture model for microscopic unmixing. The nonlinear mixture model is derived from a bidirectional reflectance distribution function for microscopic mixtures. The algorithm is designed to unmix hyperspectral images composed of macroscopic or microscopic mixtures. The mixture types and abundances at each pixel can be estimated directly from the data without prior knowledge of mixture types. Endmembers can also be estimated. Results are presented using synthetic data sets of macroscopic and microscopic mixtures and using well-known, well-characterized laboratory data sets. The unmixing accuracy of this new physics-based algorithm is compared to linear methods and to results published for other nonlinear models. The proposed method achieves the best unmixing accuracy.

TI Variance of matrix metalloproteinase (MMP) and tissue inhibitor of metalloproteinase (TIMP) concentrations in activated, concentrated platelets from healthy male donors SO JOURNAL OF ORTHOPAEDIC SURGERY AND RESEARCH LA English DT Article DE Platelet-rich plasma (PRP); MMP; TIMP; ADAMTS13; Wound healing; Tissue remodeling ID RICH PLASMA; SPORTS-MEDICINE; GROWTH-FACTOR; MEGAKARYOCYTES; EFFICACY; TENDON AB Background: The use of autologous blood concentrates, such as activated, concentrated platelets, in orthopaedic clinical applications has had mixed results. Research on this topic has focused on growth factors and cytokines, with little directed towards matrix metalloproteinases (MMPs) which are involved in post-wound tissue remodeling. Methods: In this study, the authors measured the levels of MMP-2, MMP-9 and a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 (ADAMTS13), in activated platelets derived from blood of healthy, male volunteers (n = 92), 19 to 60 years old. The levels of the natural inhibitors of these proteases, tissue inhibitor of metalloproteinase 1 (TIMP-1), TIMP-2 and TIMP-4 were also assessed. Results: Notably, there was no significant change in concentration with age in four of six targets tested. However, TIMP-2 and TIMP-4 demonstrated a statistically significant increase in concentration for subjects older than 30 years of age compared to those 30 years and younger (P = 0.04 and P = 0.04, respectively). Conclusion: TIMP-2 and TIMP-4 are global inhibitors of MMPs, including MMP-2 (Gelatinase A). MMP-2 targets native collagens, gelatin and elastin to remodel the extracellular matrix during wound healing. A decreased availability of pharmacologically active MMP-2 may diminish the effectiveness of the use of activated, concentrated platelets from older patients, and may also contribute to longer healing times in this population.

TI Sample-ready multiplex qPCR assay for detection of malaria SO MALARIA JOURNAL LA English DT Article ID TIME PCR ASSAY; PLASMODIUM-FALCIPARUM; QUANTITATIVE PCR; IMPORTED MALARIA; DIAGNOSIS; AMPLIFICATION; MICROSCOPY; PARASITES; RNA; DNA AB Background: Microscopy and antigen detecting rapid diagnostic tests are the diagnostic tests of choice in management of clinical malaria. However, due to their limitations, the need to utilize more sensitive methods such as real-time PCR (qPCR) is evident as more studies are now utilizing molecular methods in detection of malaria. Some of the challenges that continue to limit the widespread utilization of qPCR include lack of assay standardization, assay variability, risk of contamination, and the need for cold-chain. Lyophilization of molecular assays can overcome some of these limitations and potentially enable widespread qPCR utilization. Methods: A recently published multiplex malaria qPCR assay was lyophilized by freezing drying into Sample-Ready T format (MMSR). MMSR assay contained all the required reagents for qPCR including primers and probes, requiring only the addition of water and sample to perform qPCR. The performance of the MMSR assay was compared to the non-freeze dried, "wet" assay. Stability studies were done by maintaining the MMSR assays at four different ambient temperatures of 4 degrees C, room temperature (RT), 37 degrees C and 42 degrees C over a period of 42 days, tested at seven-day intervals. Plasmodium falciparum and Plasmodium vivax DNAs were used for analysis of the MMSR assay either as single or mixed parasites, at two different concentrations. The CT values and the standard deviations (SD) were used in the analysis of the assay performance. Results: The limit of detection for the MMSR assay was 0.244 parasites/mu L for Plasmodium spp. (PLU) and P. falciparum (FAL) assay targets compared to "wet" assay which was 0.39 and 3.13 parasites/mu L for PLU and FAL assay targets, respectively. The MMSR assay performed with high efficiencies similar to those of the "wet" assay and was stable at 37 degrees C for 42 days, with estimated shelf-life of 5 months. When used to analyse field clinical samples, MMSR assay performed with 100% sensitivity and specificity compared to the "wet" assay. Conclusion: The MMSR assay has the same robust performance characteristics as the "wet" assay and is highly stable. Availability of MMSR assay allows flexibility and provides an option in choosing assay for malaria diagnostics depending on the application, needs and budget.

As a result, significant variation exists in the reported results. Recently, we found that one source of variation was the use of various catalysts, and have therefore evaluated its three forms. In this paper, we characterize three substrates under near uniform reaction conditions using the most active catalytic form of the toxin. Bovine serum albumin at varying optimum concentrations stimulated enzymatic activity with all three substrates. Sodium chloride had a stimulating effect on the full length synaptosomal-associated protein of 25 kDa (SNAP25) and its 66-mer substrates but had an inhibitory effect on the 17-mer substrate. We found that under optimum conditions, full length SNAP25 was a better substrate than its shorter 66-mer or 17-mer forms both in terms of k(cat), K-m, and catalytic efficiency k(cat)/K-m. Assay times greater than 15 min introduced large variations and significantly reduced the catalytic efficiency. In addition to characterizing the three substrates, our results identify potential sources of variations in previous published results, and underscore the importance of using well-defined reaction components and assay conditions.

The Bp genome encodes a repertoire of virulence factors, including the cluster 3 type III secretion system (T3SS-3), the cluster 1 type VI secretion system (T6SS-1), and the intracellular motility protein BimA, that enable the pathogen to invade both phagocytic and non-phagocytic cells. A unique hallmark of Bp infection both in vitro and in vivo is its ability to induce cell-to-cell fusion of macrophages to form multinucleated giant cells (MNGCs), which to date are semi-quantitatively reported following visual inspection. Results: In this study we report the development of an automated high-content image acquisition and analysis assay to quantitate the Bp induced MNGC phenotype. Validation of the assay was performed using T6SS-1 (Delta hcp1) and T3SS-3 (Delta bsaZ) mutants of Bp that have been previously reported to exhibit defects in their ability to induce MNGCs. Finally, screening of a focused small molecule library identified several Histone Deacetylase (HDAC) inhibitors that inhibited Bp-induced MNGC formation of macrophages. Conclusions: We have successfully developed an automated HCI assay to quantitate MNGCs induced by Bp in macrophages. This assay was then used to characterize the phenotype of the Bp mutants for their ability to induce MNGC formation and identify small molecules that interfere with this process. Successful application of chemical genetics and functional reverse genetics siRNA approaches in the MNGC assay will help gain a better understanding of the molecular targets and cellular mechanisms responsible for the MNGC phenotype induced by Bp, by other bacteria such as Mycobacterium tuberculosis, or by exogenously added cytokines.

In this work, we report the changes in band gaps in a few layers of chemical vapor deposition processed as-grown h-BN using a simple oxygen plasma treatment. Optical absorption spectra show a trend of band gap narrowing monotonically from 6 eV of pristine h-BN to 4.31 eV when exposed to oxygen plasma for 12 s. The narrowing of band gap causes the reduction in electrical resistance by similar to 100 fold. The x-ray photoelectron spectroscopy results of plasma treated hexagonal boron nitride surface show the predominant doping of oxygen for the nitrogen vacancy. Energy sub-band formations inside the band gap of h-BN, due to the incorporation of oxygen dopants, cause a red shift in absorption edge corresponding to the band gap narrowing.

To identify pre-enlistment, demographic, and servicerelated risk factors for back-related disability in enlisted US soldiers and Marines comparing those who were deployed with those who did not deploy during the service term. Summary of Background Data. Back conditions are a major cause of morbidity and lost work days in both the US working population and military. Back-related conditions are among the most prevalent causes of military disability discharge but little research has been conducted to identify risk factors for back-related disabilities in this population. Methods. Cases included enlisted Army and Marine Corps service members evaluated for back-related disability. Controls, frequency matched by year of military entrance and service, were selected from the enlisted service member population. Pre-enlistment demographic and medical characteristics, deployment, and ambulatory care data collected from existing military databases were used. Crude and adjusted odds of back-related disability were modeled using conditional logistic regression. Results. In adjusted models, service members who were overweight (odds ratio [OR]: 1.17; 95% confidence interval [95% CI]: 1.12-1.23) and obese (OR: 1.35; 95% CI: 1.26-1.44), between ages 25 and 29 years (OR: 1.23; 95% CI: 1.16-1.31), or 30 years or older (OR: 1.43; 95% CI: 1.34-1.52) at military entrance were at increased odds of a back-related disability. History of a back diagnosis at the pre-enlistment medical examination (OR: 1.94; 95% CI: 1.50-2.50) and deploying once (OR: 1.09; 95% CI: 1.05-1.14) were also associated with increased odds of a back-related disability. Conclusion. Enlisted soldiers and marines with back-related disabilities were more likely to be older, have a higher body mass index, have a history of pre-enlistment back conditions, and were deployed once, compared with controls without a back-related disability. Additional research is necessary to further examine the complex relationship between deployment to combat zones, onset of musculoskeletal symptoms, and back-related disability in soldiers and marines.

Electrical characterization and LFN measurements were conducted on MoS2 FETs with Al2O3 top-surface passivation. We also studied the effect of top-surface passivation etching on the electrical characteristics of the device. Significant decrease in channel current and transconductance was observed in these devices after the Al2O3 passivation etching. For passivated devices, the two-terminal resistance variation with temperature showed a good fit to the activation energy model, whereas for the etched devices the trend indicated a hopping transport mechanism. A significant increase in the normalized drain current noise power spectral density (PSD) was observed after the etching of the top passivation layer. The observed channel current noise was explained using a standard unified model incorporating carrier number fluctuation and correlated surface mobility fluctuation mechanisms. Detailed analysis of the gate-referred noise voltage PSD indicated the presence of different trapping states in passivated devices when compared to the etched devices. Etched devices showed weak temperature dependence of the channel current noise, whereas passivated devices exhibited near-linear temperature dependence.

In recent years, plants have been used to produce recombinant proteins, including subunit vaccines. A subunit influenza vaccine, HAC1, based on recombinant hemagglutinin from the 2009 pandemic A/California/04/2009 (HI NI) strain of influenza virus, has been manufactured using a plant virus-based transient expression technology in Nicotiana benthamiana plants and demonstrated to be immunogenic and safe in pre-clinical studies (Shoji et al., 2011). Methods: A first-in-human, Phase 1, single-center, randomized, placebo-controlled, single-blind, dose escalation study was conducted to investigate safety, reactogenicity and immunogenicity of an HAC1 formulation at three escalating dose levels (15 mu g, 45 mu g and 90 mu g) with and without Alhydrogel (R), in healthy adults 18-50 years of age (inclusive). Eighty participants were randomized into six study vaccine groups, a saline placebo group and an approved monovalent H1N1 vaccine group. Recipients received two doses of vaccine or placebo (except for the monovalent HI NI vaccine cohort, which received a single dose of vaccine, later followed by a dose of placebo). Results: The experimental vaccine was safe and well tolerated, and comparable to placebo and the approved monovalent HI NI vaccine. Pain and tenderness at the injection site were the only local solicited reactions reported following vaccinations. Nearly all adverse events were mild to moderate in severity. The HAC1 vaccine was also immunogenic, with the highest seroconversion rates, based on serum hemagglutination-inhibition and virus microneutralization antibody titers, in the 90 mu g non-adjuvanted HAC1 vaccine group after the second vaccine dose (78% and 100%, respectively). Conclusions: This is the first study demonstrating the safety and immunogenicity of a plant-produced subunit HI NI influenza vaccine in healthy adults. The results support further clinical investigation of the HAC1 vaccine as well as demonstrate the feasibility of the plant-based technology for vaccine antigen production.

TI Simultaneous removal of perchlorate and energetic compounds in munitions wastewater by zero-valent iron and perchlorate-respiring bacteria SO JOURNAL OF ENVIRONMENTAL SCIENCE AND HEALTH PART A-TOXIC/HAZARDOUS SUBSTANCES & ENVIRONMENTAL ENGINEERING LA English DT Article DE Munitions wastewater; zero-valent iron; perchlorate; RDX; perchlorate-respiring bacteria ID PACKED-BED BIOREACTOR; ELEMENTAL IRON; MICROBIAL REDUCTION; GAS-PHASE; AZO DYES; BIODEGRADATION; 2,4-DINITROTOLUENE; PRETREATMENT; DEGRADATION; NITRATE AB Ammonium perchlorate is one of the main constituents in Army's insensitive melt-pour explosive, PAX-21 in addition to RDX and 2,4-dinitroanisole (DNAN). The objective of this study is to develop an innovative treatment process to remove both perchlorate and energetic compounds simultaneously from PAX-21 production wastewater. It was hypothesized that the pretreatment of PAX-21 wastewater with zero-valent iron (ZVI) would convert energetic compounds to products that are more amenable for biological oxidation and that these products serve as electron donors for perchlorate-reducing bacteria. Results of batch ZVI reduction experiments showed that DNAN was completely reduced to 2,4-diaminoanisole and RDX was completely reduced to formaldehyde. Anaerobic batch biodegradation experiments showed that perchlorate (30mg L-1) in ZVI-treated PAX-21 wastewater was decreased to an undetectable level after 5days. Batch biodegradation experiments also confirmed that formaldehyde in ZVI-treated wastewater was the primary electron donor for perchlorate-respiring bacteria. The integrated iron-anaerobic bioreactor system was effective in completely removing energetic compounds and perchlorate from the PAX-21 wastewater without adding an exogenous electron donor. This study demonstrated that ZVI pretreatment not only removed energetic compounds, but also transformed energetic compounds to products that can serve as the source of electrons for perchlorate-respiring bacteria.

We explored whether polyvinylpyrrolidone-coated silver nanoparticles (PVP-AgNPs) cause effects through intact nanoparticles or dissolved silver. Females of the model species fathead minnow (Pimephales promelas) were exposed to either 4.8 mu g/L of AgNO3 or 61.4 mu g/L of PVP-AgNPs for 96h. Microarray analyses were used to identify impacted receptors and toxicity pathways in liver and brain tissues that were confirmed using in vitro mammalian assays. AgNO3 and PVP-AgNP exposed fish had common and distinct effects consistent with both intact nanoparticles and dissolved silver causing effects. PVP-AgNPs and AgNO3 both affected pathways involved in Na+, K+, and H+ homeostasis and oxidative stress but different neurotoxicity pathways. In vivo effects were supported by PVP-AgNP activation of five in vitro nuclear receptor assays and inhibition of ligand binding to the dopamine receptor. AgNO3 inhibited ligand binding to adrenergic receptors alpha 1 and alpha 2 and cannabinoid receptor CB1, but had no effect in nuclear receptor assays. PVP-AgNPs have the potential to cause effects both through intact nanoparticles and metal ions, each interacting with different initiating events. Since the in vitro and in vivo assays examined here are commonly used in human and ecological hazard screening, this work suggests that environmental health assessments should consider effects of intact nanoparticles in addition to dissolved metals.

TI Evaluation of Elbow Pain in Adults SO AMERICAN FAMILY PHYSICIAN LA English DT Article ID OLECRANON BURSITIS; UPPER EXTREMITY; NERVE INJURIES; EPICONDYLITIS; MANAGEMENT; ENTRAPMENT; NEUROPATHIES; DIAGNOSIS; OVERUSE; ATHLETE AB The elbow is a complex joint designed to withstand a wide range of dynamic exertional forces. The location and quality of elbow pain can generally localize the injury to one of the four anatomic regions: anterior, medial, lateral, or posterior. The history should include questions about the onset of pain, what the patient was doing when the Pain started, and the type and frequency of athletic and occupational activities. Lateral and medial epicondylitis are two of the more common diagnoses and often occur as a result of occupational activities. Patients have pain and tenderness over the affected tendinous insertion that are accentuated with specific movements. If lateral and medial epicondylitis treatments are unsuccessful, ulnar neuropathy and radial tunnel syndrome should be considered. Ulnar collateral ligament injuries occur in athletes participating in sports that involve overhead throwing. Biceps tendinopathy is a relatively common source of pain in the anterior elbow; history often includes repeated elbow flexion with forearm supination and pronation. Olecranon bursitis is a common cause of posterior elbow pain and swelling. It can be septic or aseptic, and is diagnosed based on history, physical examination, and bursal fluid analysis if necessary. Plain radiography is the initial choice for the evaluation of acute injuries and is best for showing bony injuries, soft tissue swelling, and joint effusions. Magnetic resonance imaging is the preferred imaging modality for chronic elbow pain. Musculoskeletal ultrasonography allows for an inexpensive dynamic evaluation of commonly injured structures.

TI Fifteen node tetrahedral elements for explicit methods in nonlinear solid dynamics SO COMPUTER METHODS IN APPLIED MECHANICS AND ENGINEERING LA English DT Article DE Nonlinear solid dynamics; Second-order finite elements; Tetrahedron Explicit time integration; Mass matrix diagonalization; Mass lumping ID ASSUMED STRAIN STABILIZATION; COMPOSITE FINITE-ELEMENTS; QUADRATURE-FORMULAS; HOURGLASS CONTROL AB Despite the ease in meshing and benefits for modeling flexure, curved shapes, etc., secondorder tetrahedral elements are not contained in typical explicit solid dynamic programs. This is primarily due to the lack of both a satisfactory consistent nodal loading distribution and mass lumping technique. Row summation lumping, for instance, produces negative vertex node masses for the popular ten node "serendipity" tetrahedron, which also has zero vertex node loads resulting from a constant pressure on an element face. This has led to piecewise composites of four node tetrahedrons to represent a ten node one in explicit codes. In this paper, truly second-order fifteen node formulations for compressible and for nearly incompressible materials are presented and evaluated. In addition to producing all positive nodal loads from a uniform traction, row summation mass lumping for the fifteen node element is shown to produce all positive nodal masses. Performance is assessed in standard benchmark problems and practical applications using various elastic and elastic plastic material models and involving very large strains/deformations, severe distortions, and contact-impact. Comparisons are also made with several first-order elements and second-order hexahedral formulations. The offered elements performed satisfactorily in all examples. As recently found for second-order hexahedral elements, it is shown that the inclusion of face and centroidal nodes is vital for robust performance with row summation lumping, and high-order quadrature rules are crucial with explicit methods. These second-order elements are shown to be viable for practical applications, especially using today's parallel computers. Whereas the reliable performance is generally attained at significant computational expense compared with first-order and brick types, these elements can be more computationally competitive in flexure and have the desirable trait that they are amenable to automatic tetrahedral meshing software.

TI Applying EEG phase synchronization measures to non-linearly coupled neural mass models SO JOURNAL OF NEUROSCIENCE METHODS LA English DT Article DE Phase synchronization; Neural mass models; Phase locking value; Phase lag index; Imaginary coherence ID BRAIN ACTIVITY; FUNCTIONAL CONNECTIVITY; VISUAL-CORTEX; LAG INDEX; DYNAMICS; OSCILLATIONS; NETWORKS; RHYTHMS; MEG; ORGANIZATION AB Background: Recent neuroimaging analyses aim to understand how information is integrated across brain regions that have traditionally been studied in isolation; however, detecting functional connectivity networks in experimental EEG recordings is a non-trivial task. New method: We use neural mass models to simulate 10-s trials with coupling between 1-3 and 5-8 s and compare how well three phase-based connectivity measures recover this connectivity pattern across a set of experimentally relevant conditions: variable oscillation frequency and power spectrum, feed forward connections with or without feedback, and simulated signals with and without volume conduction. Results: Overall, the results highlight successful detection of the onset and offset of significant synchronizations for a majority of the 28 simulated configurations; however, the tested phase measures sometimes differ in their sensitivity and specificity to the underlying connectivity. Comparison with existing methods: Prior work has shown that these phase measures perform well on signals generated by a computational model of coupled oscillators. In this work we extend previous studies by exploring the performance of these measures on a different class of computational models, and we compare the methods on 28 variations that capture a set of experimentally relevant conditions. Conclusions: Our results underscore that no single phase synchronization measure is substantially better than all others, and experimental investigations will likely benefit from combining a set of measures together that are chosen based on both the experimental question of interest, the signal to noise ratio in the EEG data, and the approach used for statistical significance.

The US Army is developing tafenoquine (TQ), an analogue of primaquine (PQ), which is expected to be more effective in preventing malaria in deployed military personnel. Methods: To compare the prophylactic efficacy of TQ and PQ, a transgenic Plasmodium berghei parasite expressing the bioluminescent reporter protein luciferase was utilized to visualize and quantify parasite development in C57BL/6 albino mice treated with PQ and TQ in single or multiple regimens using a real-time in vivo imaging system (IVIS). As an additional endpoint, blood stage parasitaemia was monitored by flow cytometry. Comparative pharmacokinetic (PK) and liver distribution studies of oral and intravenous PQ and TQ were also performed. Results: Mice treated orally with three doses of TQ at 5 mg/kg three doses of PQ at 25 mg/kg demonstrated no bioluminescence liver signal and no blood stage parasitaemia was observed suggesting both drugs showed 100% causal activity at the doses tested. Single dose oral treatment with 5 mg TQ or 25 mg of PQ, however, yielded different results as only TQ treatment resulted in causal prophylaxis in P. berghei sporozoite-infected mice. TQ is highly effective for causal prophylaxis in mice at a minimal curative single oral dose of 5 mg/kg, which is a five-fold improvement in potency versus PQ. PK studies of the two drugs administered orally to mice showed that the absolute bioavailability of oral TQ was 3.5-fold higher than PQ, and the AUC of oral TQ was 94-fold higher than oral PQ. The elimination half-life of oral TQ in mice was 28 times longer than PQ, and the liver tissue distribution of TQ revealed an AUC that was 188-fold higher than PQ. Conclusions: The increased drug exposure levels and longer exposure time of oral TQ in the plasma and livers of mice highlight the lead quality attributes that explain the much improved efficacy of TQ when compared to PQ.

The UV-LIF-RDI technique measured LIF spectra via direct laser beam illumination onto the particles that were impacted on a RDI strip with a spatial resolution of 1.2 mm, equivalent to an averaged time resolution in the aerosol sampling of 3.6 h. Excited by a 263 nm or 351 nm laser, more than 2000 LIF spectra within a 3-week aerosol collection time period were obtained from the eight individual RDI strips that collected particles in eight different sizes ranging from 0.09 to 10 mu m in Djibouti. Based on the known fluorescence database from atmospheric aerosols in the US, the LIF spectra obtained from the Djibouti aerosol samples were found to be dominated by fluorescence clusters 2,5, and 8 (peaked at 330, 370, and 475 nm) when excited at 263 nm and by fluorescence clusters 1, 2, 5, and 6 (peaked at 390 and 460 nm) when excited at 351 nm. Size- and time-dependent variations of the fluorescence spectra revealed some size and time evolution behavior of organic and biological aerosols from the atmosphere in Djibouti. Moreover, this analytical technique could locate the possible sources and chemical compositions contributing to these fluorescence clusters. Advantages, limitations, and future developments of this new aerosol analysis technique are also discussed. Published by Elsevier B.V.

CA Infect Dis Clinical Res Program Tr TI Biofilms and persistent wound infections in United States military trauma patients: a case-control analysis SO BMC INFECTIOUS DISEASES LA English DT Article DE Biofilm; Risk factors; Trauma-related infections; Persistent infections; Chronic infections; Extremity wound infections ID IN-VITRO MODEL; OPERATION ENDURING FREEDOM; FIELD GEL-ELECTROPHORESIS; D-AMINO ACIDS; EXTREMITY INJURIES; ACINETOBACTER-CALCOACETICUS; ESCHERICHIA-COLI; OUTCOMES; IRAQ; WAR AB Background: Complex traumatic injuries sustained by military personnel, particularly when involving extremities, often result in infectious complications and substantial morbidity. One factor that may further impair patient recovery is the persistence of infections. Surface-attached microbial communities, known as biofilms, may play a role in hindering the management of infections; however, clinical data associating biofilm formation with persistent or chronic infections are lacking. Therefore, we evaluated the production of bacterial biofilms as a potential risk factor for persistent infections among wounded military personnel. Methods: Bacterial isolates and clinical data from military personnel with deployment-related injuries were collected through the Trauma Infectious Disease Outcomes Study. The study population consisted of patients with diagnosed skin and soft-tissue infections. Cases (wounds with bacterial isolates of the same organism collected 14 days apart) were compared to controls (wounds with non-recurrent bacterial isolates), which were matched by organism and infectious disease syndrome. Potential risk factors for persistent infections, including biofilm formation, were examined in a univariate analysis. Data are expressed as odds ratios (OR; 95% confidence interval [CI]). Results: On a per infected wound basis, 35 cases (representing 25 patients) and 69 controls (representing 60 patients) were identified. Eight patients with multiple wounds were utilized as both cases and controls. Overall, 235 bacterial isolates were tested for biofilm formation in the case-control analysis. Biofilm formation was significantly associated with infection persistence (OR: 29.49; CI: 6.24-infinity) in a univariate analysis. Multidrug resistance (OR: 5.62; CI: 1.02-56.92), packed red blood cell transfusion requirements within the first 24 hours (OR: 1.02; CI: 1.01-1.04), operating room visits prior to and on the date of infection diagnosis (OR: 2.05; CI: 1.09-4.28), anatomical location of infected wound (OR: 5.47; CI: 1.65-23.39), and occurrence of polymicrobial infections (OR: 69.71; CI: 15.39-infinity) were also significant risk factors for persistent infections. Conclusions: We found that biofilm production by clinical strains is significantly associated with the persistence of wound infections. However, the statistical power of the analysis was limited due to the small sample size, precluding a multivariate analysis. Further data are needed to confirm biofilm formation as a risk factor for persistent wound infections.

One limitation to mitigating the impacts of dams on fish is that we have a poor understanding of why some fish enter routes engineered for their safe travel around the dam but others pass through more dangerous routes. To understand fish movement through hydropower dam environments, we combine a computational fluid dynamics model of the flow field at a dam and a behavioral model in which simulated fish adjust swim orientation and speed to modulate their experience to water acceleration and pressure (depth). We fit the model to data on the passage of juvenile Pacific salmonids (Oncorhynchus spp.) at seven dams in the Columbia/Snake River system. Our findings from reproducing observed fish movement and passage patterns across 47 flow field conditions sampled over 14 y emphasize the role of experience and perception in the decision making of animals that can inform opportunities and limitations in living resources management and engineering design.

A III-V semiconductor gain chip is edge-coupled into a SOI cavity chip through a SiNx spot size converter and Si grating couplers are incorporated to enable wafer-scale characterization. The laser output power reaches 20 mW and the highest wall-plug efficiency of 7.8% is measured at 17.3 mW in un-cooled condition. The laser wavelength tuning ranges are 8 nm for the single ring reflector cavity and 35 nm for the vernier ring reflector cavity, respectively. The Si hybrid laser is a promising light source for energy-efficient Si CMOS photonic links.

TI Why the Internet Is Not Increasing Terrorism SO SECURITY STUDIES LA English DT Article AB Policymakers and scholars fear that the Internet has increased the ability of transnational terrorists, like al Qaeda, to attack targets in the West, even in the face of increased policing and military efforts. Although access to the Internet has increased across the globe, there has been no corresponding increase in completed transnational terrorist attacks. This analysis examines the causal logics-which have led to the conventional wisdom-and demonstrates both theoretically and empirically that the Internet is not a force multiplier for transnational terrorist organizations. Far from being at a disadvantage on the Internet, state security organs actually gain at least as much utility from the Internet as terrorist groups do, meaning that at worst the Internet leaves the state in the same position vis-a-vis terrorist campaigns as it was prior to the Internet.

The size and composition of these bioclusters contribute to the protection of the organisms within the core of cluster from the harmful effects of ambient UV light. The use of ultraviolet irradiation has been evaluated in the past as an option for decontaminating surfaces and air; however, previous studies were conducted with single spores, or poorly characterized polydispersed aerosols making comparisons between studies difficult. This study is intended to evaluate the effect of UV-C irradiation on monodispersed particles of spore clusters with mean diameters of 2.8 mu m and 4.4 mu m, and single spores of Bacillus atrophaeus var. globigii on fixed surfaces and as aerosol. The D-90, the UV-C irradiation doses at which 90% of the colony forming units were rendered nonculturable, for single spores and spore clusters of 2.8 and 4.4 mu m on surfaces were 138, 725, and 1128 J/m(2), respectively. The respective values for airborne spores were 27, 42, and 86-94 J/m(2). The first-stage decay rate constant for the surface exposure ranged from 0.012 for single spores to 0.003 for 4.4 mu m clusters. Similarly, the aerosol decay rate constant ranged from 0.12 for single spores to 0.04 for 4.4 mu m clusters. The results of this study demonstrate that the decay rate of spores contained in clusters is proportional to the overall particle size, and that it is harder to inactivate large clusters on surfaces.

Driven by the need, the current article reports for the first time gold nanocage-graphene oxide hybrid platform for the spectral fingerprint and the trace level identification of RDX and TNT. Reported experimental data using RDX show that the surface-enhanced Raman spectroscopy (SERS) enhancement factor for graphene oxide (GO) attached gold nanocage assembly is 4 orders of magnitude higher than only nanocage, and it is due to the enormous field enhancement for the nanocage assembly. The current article demonstrates that label-free nitro-explosive identification limits using hybrid platform can be as low as 10 fM for TNT and 500 fM for RDX, which indicate that gold nanocage graphene oxide assembly can be very attractive for a variety of practical applications.

We extend the notion of local-centrality, a centrality measure previously shown to correspond with a node's ability to spread an epidemic, to sets of nodes by introducing combinatorial local centrality. Though we prove that finding a set of nodes that maximizes this new measure is NP-hard, good approximations are available. We show that a strictly greedy approach obtains the best approximation ratio unless P = NP and then formulate a modified version of this approach that leverages qualities of the network to achieve a faster runtime while maintaining this theoretical guarantee. We perform an experimental evaluation on samples from several different network structures which demonstrate that our algorithm maximizes combinatorial local centrality and consistently chooses the most effective set of nodes to spread infection under the SIR model, relative to selecting the top nodes using many common centrality measures. We also demonstrate that the optimized algorithm we develop scales effectively. C1 [Moores, Geoffrey; Shakarian, Paulo] US Mil Acad, Elect Engn & Comp Sci Dept, West Point, NY 10996 USA.

TI Heat Removal Using Microclimate Foot Cooling: A Thermal Foot Manikin Study SO AVIATION SPACE AND ENVIRONMENTAL MEDICINE LA English DT Article DE heat strain; heat transfer; liquid cooling ID SKIN TEMPERATURE; EXERCISE; FEET AB Background: It has been proposed that microclimate cooling systems exploit the peripheral extremities because of more efficient heat transfer. The purpose of this study was to quantify, using a patented microclimate cooling technique, the heat transfer from the plantar surface of the foot for comparison to other commonly cooled body regions. Methods: A military boot was fitted with an insole embedded with a coiled, 1.27 m length of hollow tubing terminating in inlet and outlet valves. A thermal foot manikin with a surface temperature of 34 degrees C was placed in the boot and the valves were connected to a system that circulated water through the insole at a temperature of 20 degrees C and flow rate of 120 ml.min(-1). The manikin foot served as a constant heat source to determine heat transfer provided by the insole. Testing was done with the foot model dry and sweating at a rate of 500 ml.h(-1).m(-2). Climatic chamber conditions were 30 degrees C with 30% RH. Results: Heat loss was similar to 4.1 +/- 0.1 and similar to 7.7 +/- 0.3 W from the dry and sweating foot models, respectively. On a relative scale, the heat loss was 3.0 W and 5.5 W per 1% (unit) body surface area, respectively, for the dry and sweating conditions. Discussion:The relative heat loss afforded by plantar foot cooling was similar compared to other body regions, but the absolute amount of heat removal is unlikely to make an impact on whole body heat balance.

TI Periorbital nodular fasciitis arising during pregnancy SO INDIAN JOURNAL OF OPHTHALMOLOGY LA English DT Article DE Nodular fasciitis; periorbital; pregnancy; sarcoma AB Nodular fasciitis (NF) is a benign proliferation of fibroblasts and myofibroblasts that rarely occurs in the periorbital region. We report what we believe to be the first case of periorbital NF associated with pregnancy. A case of intravascular fasciitis, a NF variant, has been reported during pregnancy, but it was not located in the periorbital region. A weak presence of estrogen receptors has been reported in NF. This may make it more susceptible to the hormone-related changes during pregnancy and contribute to the development of the lesion by stimulating fibroblasts and smooth muscle cell types. Although rare, NF should be considered in the differential diagnosis of periorbital soft-tissue masses arising during pregnancy.

Unlike most previous approaches in compressed sensing for radar in general and SAR in particular, we take advantage of the sparsity of the scene and the correlation between the transmitted and received signal directly in the raw time domain even before attempting image formation. Our framework can be viewed as a collection of practical sparsity-driven preprocessing algorithms for radar applications that restores and denoises raw radar signals at each aperture position independently, leading to a significant reduction in the memory requirement as well as the computational complexity of the sparse recovery process. Recovery results from real-world data collected by the U. S. Army Research Laboratory (ARL) UWB SAR systems illustrate the robustness and effectiveness of our proposed framework on two critical applications: 1) recovery of missing spectral information in multiple frequency bands and 2) adaptive extraction and/or suppression of radio frequency interference (RFI) signals from SAR data records.

TI Asymmetric Acoustic Scattering for Structural Health Monitoring SO JOURNAL OF THE AMERICAN HELICOPTER SOCIETY LA English DT Article ID DAMAGE DETECTION; COMPOSITE PLATES; LOCALIZATION; PROPAGATION; INTEGRITY; DIAGNOSIS; AIRCRAFT; SYSTEMS AB Methods for constructing damage localization maps from networks of piezoelectric lead zirconate titanate (PZT) acoustic sensor measurements were investigated. A new approach, asymmetric acoustic Scattering (AAS), for damage detection and localization using PZT sensor arrays was developed, and the conclusions were favorable compared to commercial software results. The AAS method is simple, computationally efficient, and general because it does not require geometric details of the component or complex physical models. The approach estimates damage in five stages: (1) damage index (DI) measures are computed for individual sensors, (2) DI-weighted averages are computed for pairs of sensors, (3) DI-weighted averages are used to generate local DI maps, (4) local DI maps are combined into frequency-dependent global DI maps, and (5) frequency-dependent DI maps are combined into global DI maps. The AAS algorithm generates temporal DI curves to increase the confidence of damage detection, whereas damage localization is accomplished with static distributed DI maps. Accuracy, robustness, and sensor array minimization methods for improving damage detection and localization were also investigated.

TI Reduced In-Plane, Low-Frequency Noise of an Active Flap Rotor SO JOURNAL OF THE AMERICAN HELICOPTER SOCIETY LA English DT Article AB Results from a joint DARPA/Boeing/NASA/Army wind tunnel test demonstrated the ability to reduce in-plane, low-frequency noise of the full-scale Boeing-SMART(Smart Material Actuated Rotor Technology) rotor with active flaps. Test data reported in this paper illustrated that near-field acoustic energy in the first six blade-passing harmonics could be reduced by up to 6 dB at a moderate-airspeed, level flight condition at an advance ratio of 0.30. Reduced noise levels were attributed to selective active flap schedules that modified in-plane blade airloads on the advancing side of the rotor, generating counteracting acoustic pulses that partially offset the negative pressure peaks associated with in-plane, steady thickness noise. These favorable reduced-noise operating states are a strong function of the active flap actuation amplitude, frequency, and phase. The reduced noise levels resulted in reduction of predicted aural detection distance, but incurred vibratory load penalties due to increased hub shear forces.

TI Fractal Inductors SO IEEE TRANSACTIONS ON MAGNETICS LA English DT Article DE Fractals; inductor geometries; inductors; space filling curves; stretchable electronics ID THIN-FILM INDUCTORS AB This paper investigates the performance of planar inductors based on space filling curves, a family of fractals with the property of completely filling a bounded area. Fractal-based inductor design is a method for obtaining a very long trace lengths-and thus inductance densities-in 2-D space as a replacement for the serpentines currently used in one layer inductors. Because of the intricate course created by a fractal curve, these types of inductors are particularly well suited for stretchable electronics, where a tortuous path relieves mechanical stress and creates a more compliant structure. Inductors based on seven common space filling curves, all bounded within a one square millimeter area, were both simulated and measured experimentally and found to vary between 3.0 and 7.1 nH. Lower order fractals were found to give comparable performance to serpentine inductors with similar inductance density. More complicated fractals, after more than two iterations, were found to have lower inductance density than similar resistance serpentines. Mechanical simulations demonstrate a reduction in stress by a factor of 10 or more compared with the loop and serpentine designs.

Based on Andersson and Pearson's (1999) concept of the incivility spiral, Naylor, Pritchard, and Ilgen's (1980) theory of behavior in organizations, and social interactionist theory (Felson & Tedeschi, 1993), we proposed an interaction between incivility experiences, organizational climate for incivility (organizational tolerance and policies), and gender in predicting incivility perpetration. Results indicate that incivility experiences predict incivility perpetration and that men are more likely to be uncivil to others when their organization tolerates rudeness. Women's incivility experiences were associated with increased incivility perpetration, but were unaffected by incivility climate. Implications for research and practice are discussed.

Methods: The Department of Defense's Joint Theater Trauma Registry was queried for all combat casualties injured from February 1, 2002 through February 1, 2011. The search was limited to patients who required admission to the intensive care unit and survived to be evacuated to Landstuhl Regional Medical Center. Results: The query yielded 6,011 patients. The mean age was 25.7 +/- 6.2 years. The majority of patients were male (98.3%), injured in Iraq (80%) and were members of the U. S. Army (72.6%). Most patients (58.0%) had an injury severity score in the lowest severity category (0-15). The mortality rate was 1.8%. The median day of death after injury (interquartile range) was 6 (3-14). Conclusions: We identified a cohort of critically wounded combat casualties that encompasses the majority of such patients injured in the course of the wars in Iraq and Afghanistan. When this database is fully populated, rigorous epidemiologic analysis will seek to identify factors associated with morbidity and mortality to improve future care.

The objective of this study was to evaluate the effectiveness of omega-3 FAs (eicosapentaenoic + docosahexaenoic; Harris-Schacky [HS]-Omega-3 Index) on neuropsychological functioning among U.S. Soldiers deployed to Iraq. This randomized, double-blind, placebo-controlled trial included Soldiers between the ages of 18 and 55 years who were randomly assigned to either the active treatment group (n = 44) or placebo group (n = 34). Active treatment was 2.5 g per day of eicosapentaenoic + docosahexaenoic (Lovaza; GlaxoSmithKline, Research Triangle Park, North Carolina). The placebo was corn oil ethyl esters. HS-Omega-3 Index, a neurocognitive battery (Central Nervous System-Vital Signs, Morrisville, North Carolina), and psychological health scales were assessed at baseline and after 60 days of treatment. Although the results revealed that omega-3 FAs significantly increased the HS-Omega-3 Index (p = 0.001), there were no significant effects on indices psychological health and neurocognitive functioning by treatment group. Nevertheless, there was a significant inverse correlation between the changes in the HS-Omega-3 Index and daytime sleepiness (r = 0.30, p = 0.009). Short-term treatment with 2.5 g of omega-3 FAs did not alter measures of neurocognition or psychological health, but there was evidence of a relationship between omega-3 levels and daytime sleepiness.

TI Military Healthcare Providers Reporting of Adverse Events Following Immunizations to the Vaccine Adverse Event Reporting System SO MILITARY MEDICINE LA English DT Article ID SAFETY AB Objectives: We studied military health care provider (HCP) practices regarding reporting of adverse events following immunization (AEFI). Methods: A convenience sample of HCP was surveyed to assess familiarity with Vaccine Adverse Event Reporting System (VAERS), AEFI they were likely to report, methods used and preferred for reporting, and perceived barriers to reporting. We analyzed factors associated with HCP reporting AEFI to VAERS. Results: A total of 547 surveys were distributed with 487 completed and returned for an 89% response rate. The percentage of HCP aware of VAERS (54%) varied by occupation. 47% of respondents identified knowledge of at least one AEFI with only 34% of these indicating that they had ever reported to VAERS. More serious events were more likely to be reported. Factors associated with HCP reporting AEFIs in bivariate analysis included HCP familiarity with filing a paper VAERS report, HCP familiarity with filing an electronic VAERS report, HCP familiarity with VAERS, and time spent on immunization tasks. In a multivariable analysis, only HCP familiarity with filing a paper VAERS report was statistically significant (Odds ratio = 115.3; p < 0.001). Conclusions: Specific educational interventions targeted to military HCP likely to see AEFIs but not currently filing VAERS reports may improve vaccine safety reporting practices.

TI Intravenous Angiocatheters as a Novel Alternative to Semmes-Weinstein Monofilament Evaluation in Testing Protective Sensation SO MILITARY MEDICINE LA English DT Article ID DIABETIC FOOT ULCERATION; PERIPHERAL NEUROPATHY; HIGH-RISK; OUTCOMES AB Semmes-Weinstein monofilament (SWM) evaluation for protective sensation in diabetic feet is a widely used tool to guide patient care. Little evidence is available for alternative testing modalities for use when monofilament is not available or is deformed. Multiple varieties of intravenous angiocatheter tubing were subjected to biomechanical testing on a digital scale to assess the force generated once bending was observed by five independently tested raters. A 5.07 SWM (10 g) was tested in similar manner to establish a baseline and validate testing methodology. The 24 gauge x 0.75 in angiocatheter measured the closest to the 5.07 SWM (10 g) at an average force of 22 +/- 0.91 g compared with 10.2 +/- 0.13 g. Large-gauge angiocatheters measured greater forces. High intra-rater and inter-rater reliability was observed with all values greater than 0.98 (p < 0.001). A 24 gauge x 0.75 in angiocatheter tubing can be used as an alternative to the standard 5.07 SWM (10 g) for testing protective sensation in diabetic feet. Reviewing previously published receiver operating characteristics, this modality would yield estimated sensitivity and specificity values greater than 0.8 and 0.7, respectively, for detecting insensate feet tested at the bilateral metatarsal heads.

TI An Analysis of Staphylococcus aureus Infections at a Military Medical Center Using the PLEX-ID Combined Polymerase Chain Reaction-Mass Spectrometry System SO MILITARY MEDICINE LA English DT Article ID TOXIC-SHOCK-SYNDROME; METHICILLIN-RESISTANT; STRAINS; ORIGIN; USA300 AB Staphylococcus aureus (S. aureus) is a major cause of morbidity in the military health care setting. Culture-based methods are the most common means of identifying infections caused by this agent. However, culture-based methods lack sensitivity and specificity. The Abbott PLEX-ID instrument uses a combination of the polymerase chain reaction and mass spectrometry for the identification of bacterial isolates. We investigated whether the Abbott PLEX-ID system could identify S. aureus in clinical material and facilitate the epidemiological analysis of individual isolates. The PLEX-ID system positively identified 100% of isolates previously found to be methicillin resistant S. aureus by culture. In addition, analysis using the PLEX-ID software revealed that the majority of S. aureus isolates at Tripler Army Medical Center derive from clonal complex 8 and nearly 100% of these strains express the R-variant of the Panton-Valentine leukocidin virulence factor. These results demonstrate the utility of the PLEX-ID system in identifying clinical isolates and reveal an unexpected level of homogeneity among clinical S. aureus isolates recovered at Tripler Army Medical Center. These results also demonstrate the utility of the PLEX-ID system in identifying the resistance patterns, predicting the virulence properties, and tracking the migration of bacterial pathogens in the clinical setting.

Surface NMR (sNMR) and TEM soundings, laboratory NMR, complex resistivity, and X-Ray Diffraction (XRD) analysis were all conducted to characterise the distribution of water within Sherman Crater on Mt. Baker, WA. Clay rich rocks, particularly if water saturated, can weaken volcanoes, thereby increasing the potential for catastrophic sector collapses that can lead to far-travelled, destructive debris flows. Detecting the presence and volume of shallow groundwater is critical for evaluating these landslide hazards. The TEM data identified a low resistivity layer (<10 ohm-m), under 60 m of glacial ice related to water saturated clays. The TEM struggles to resolve the presence or absence of a plausible thin layer of bulk liquid water on top of the clay. The sNMR measurements did not produce any observable signal, indicating the lack of substantial accumulated bulk water below the ice. Laboratory analysis on a sample from the crater wall that likely represented the clays beneath the ice confirmed that the controlling factor for the lack of sNMR signal was the fine-grained nature of the media. The laboratory measurements further indicated that small pores in clays detected by the XRD contain as much as 50% water, establishing an upper bound on the water content in the clay layer. Forward modelling of geologic scenarios revealed that bulk water layers as thin as m between the ice and clay layer would have been detectable using sNMR. The instrumentation conditions which would allow for sNMR detection of the clay layer are investigated. Using current instrumentation the combined analysis of the TEM and sNMR data allow for valuable characterisation of the groundwater system in the crater. The sNMR is able to reduce the uncertainty of the TEM in regards to the presence of a bulk water layer, a valuable piece of information in hazard assessment.

Internal erosion can be a difficult failure mode of dams and levees to assess using traditional techniques. Surface nuclear magnetic resonance is a promising technology for monitoring these structures due to its direct sensitivity to liquid water. This is a new application for the method, and requires the formulation of a robust modelling framework capable of incorporating three dimensional water content models and topography. Adaptive octree meshes represent an efficient means to perform these calculations, as they are able to adapt and refine in areas where the kernel function is changing rapidly. Given the non-trivial challenges associated with the development of realistic water content models, we focus on first-order effects and present six 2.5D flow models representing seepage through a loaded earthen embankment under varying levels of erosional piping. Simulation results show that the employment of multiple surface nuclear magnetic resonance transmitter and receiver loops can provide early detection and effective monitoring of piping under the assumption of a 2.5D water content model. Therefore, the surface nuclear magnetic resonance technique has promise as a means for detection and/or monitoring of internal erosion and piping in earthen embankments.

We map a broad class of related problems for data fusion in wireless sensor networks into an integer programming problem and provide an iterative Lagrangian relaxation technique to solve it. Each iteration step involves solving for a maximum-weight independent set of an appropriately constructed graph, which, in many cases, can be obtained in polynomial time. We apply our methodology to the problem of tracking targets moving over a period of time through a nonhomogeneous, energy-constrained sensor field. With rewards represented by the quality of information attained in tracking, we study its trade-offs and relationship with energy consumption and periodic measurement taking. We finally illustrate other applications of our framework in sensor networks. C1 [Hariharan, Srikanth] AT&T Labs, Austin, TX 78759 USA.

TI Texture Control in Lead Zirconate Titanate Multilayer Thin Films SO IEEE TRANSACTIONS ON ULTRASONICS FERROELECTRICS AND FREQUENCY CONTROL LA English DT Article ID MEMS APPLICATIONS; TECHNOLOGIES; ACTUATOR AB Multilayer actuators (MLAs) offer an increase of force per unit area, a reduction in power consumption, and a reduction in required driving voltages compared with single-layer actuators. For example, switching from a single 0.5- or 1.0-mu m layer of PZT to multiple 250-nm-thick layers would enable a 2/3 to 3/4 reduction in actuation voltage and an increase of 2 to 3 times in actuation force per area for a PZT MEMS switches and robotics. Efforts have been focused on developing actuators using four 250-nm-thick layers of PZT with a Zr/Ti ratio of 52/48 (i.e., the morphotropic phase boundary). The PZT films used a previously established method of achieving greater than 98% (001/100) oriented PZT by chemical solution deposition (CSD). By performing X-ray diffraction measurements between each layer, the texture within the films could be monitored during the growth process. To electrically measure the quality of the PZT multilayer stack, a series of six-sided capacitors were fabricated. The devices were connected in parallel with an average dielectric constant of 1150 for each PZT layer and an average total capacitance of 45 nF. In addition to capacitors, cantilever actuators were fabricated to measure the piezoelectric induced deformation. Comparisons with 100-mu m-long cantilever between a single 1-mu m-thick PZT and four 250-nm-thick layer PZT stack have shown comparable displacements of vertical bar 3.7 vertical bar mu m and vertical bar 4.0 vertical bar mu m, respectively, with an applied electric field of 10 V/mu m across the film. These measurements on MLA PZT films demonstrate high piezoelectric coefficients that are suitable for tactile radio and milimeter-scale robotic devices.

This analysis expands on a 2011 study that examined characteristics of a tilt-phase component discovered in the standard theory of SE turbulence effects characterization. The analysis introduces an improved integration technique and a reformulated phase structure function, facilitating computation of a 38,007 element database of MTF results at low-to high-angular frequencies covering a wide range of diffraction and turbulence conditions. Analysis of this database is described, yielding a new analytic SE MTF, accurate to a root-mean-square error of 0.000218 versus the database. Comparisons show that the new expression is well correlated to an alternative computationally intensive method, and it is a factor 29 to 64 improvement over prior analytic expressions. Limits of applicability of the approach for incoherent imaging are also discussed. The low-computational cost of the new method is suitable for systems performance modeling of turbulence impacts, including path-varying turbulence scenarios. (C) The Authors.

TI Magnetic defects in chemically converted graphene nanoribbons: electron spin resonance investigation SO AIP ADVANCES LA English DT Article ID CARBON NANOTUBES; TRANSPORT; RELAXATION; FUNCTIONALIZATION; ADSORPTION; NITROGEN; ESR AB Electronic spin transport properties of graphene nanoribbons (GNRs) are influenced by the presence of adatoms, adsorbates and edge functionalization. To improve the understanding of the factors that influence the spin properties of GNRs, local (element) spin-sensitive techniques such as electron spin resonance (ESR) spectroscopy are important for spintronics applications. Here, we present results of multi-frequency continuous wave (CW), pulse and hyperfine sublevel correlation (HYSCORE) ESR spectroscopy measurements performed on oxidatively unzipped graphene nanoribbons (GNRs), which were subsequently chemically converted (CCGNRs) with hydrazine. ESR spectra at 336 GHz reveal an isotropic ESR signal from the CCGNRs, of which the temperature dependence of its line width indicates the presence of localized unpaired electronic states. Upon functionalization of CCGNRs with 4-nitrobenzene diazonium tetrafluoroborate, the ESR signal is found to be 2 times narrower than that of pristine ribbons. NH3 adsorption/desorption on CCGNRs is shown to narrow the signal, while retaining the signal intensity and g value. The electron spin-spin relaxation process at 10 K is found to be characterized by slow (163 ns) and fast (39 ns) components. HYSCORE ESR data demonstrate the explicit presence of protons and C-13 atoms. With the provided identification of intrinsic point magnetic defects such as proton and C-13 has been reported, which are roadblocks to spin travel in graphene-based materials, this work could help in advancing the present fundamental understanding on the edge-spin (or magnetic)-based transport properties of CCGNRs.

Human operators are required to teleoperate the current generation of mobile robots for such applications; however, teleoperation is increasingly difficult as the number of robots is expanded. As the number of robots is increased, each robot may also interfere with one another and eventually decrease mapping performance. As presented here, through careful consideration of robot team coordination and exploration strategy, large numbers of mobile robots can be allocated to accomplish the mapping task more quickly and accurately. We present both the coordination and exploration strategies and present results from experiments in simulation as well as with up to nine mobile platforms.

TI Common Factors and Outcome in Late Upper Extremity Amputations After Military Injury SO JOURNAL OF ORTHOPAEDIC TRAUMA LA English DT Article DE combat-related amputation; late amputation; upper extremity amputation ID OPERATION ENDURING FREEDOM; TRAUMATIC LIMB LOSS; CURRENT CONFLICTS; ORTHOPEDIC INJURIES; OIF/OEF CONFLICTS; AMPUTEE SOLDIERS; SEVERITY SCORES; PROSTHETIC USE; IRAQ; RECONSTRUCTION AB Objectives: Much attention has been given to lower extremity amputations that occur more than 90 days after injury, but little focus has been given to analogous upper extremity amputations. The purpose of this study was to determine the reason(s) for desired amputation and the common complications after amputation for those combat-wounded service members who underwent late upper extremity amputation. Design: Retrospective case series. Setting: Tertiary trauma center. Patients/Participants: All US service members who sustained major extremity amputations from September 2001 to July 2011 were analyzed. Intervention: Late (>90 days after injury) upper extremity amputations. Main Outcome Measurements: Amputation level(s), time to amputation, age, number of operations, pre/postoperative complications, reason(s) for desiring amputation, and disability outcomes were analyzed. Results: Seven of 218 (3.2%) upper extremity amputees had a late upper extremity amputation (>90 days from injury to amputation). The mean and median number of days from injury to amputation was 689 and 678, respectively. The most common preamputation complications were loss of wrist or finger motion (7, 100%), neurogenic pain (4, 57%), and heterotopic ossification (4, 57%). Three (43%) patients (2 persistent and 1 new onset) had neurogenic pain and 2 (29%) had heterotopic ossification after amputation. Only 57% (4 of 7) of amputees used their prostheses regularly. Conclusions: Service members undergoing late upper extremity amputation seem to have different pre- and postoperative complications than those patients undergoing late lower extremity amputations. It was common for the amputee to not wear their prostheses and to experience similar complications after amputation, albeit in a less severe form. Level of Evidence: Prognostic Level IV.

TI Intraobserver and Interobserver Reliability and the Role of Fracture Morphology in Classifying Femoral Shaft Fractures in Young Children SO JOURNAL OF PEDIATRIC ORTHOPAEDICS LA English DT Article DE femoral fracture; classification; interobserver and intraobserver reliability ID CALVE-PERTHES-DISEASE; CLASSIFICATION-SYSTEM; IDIOPATHIC SCOLIOSIS; NONACCIDENTAL INJURY; ABUSE; EXPERIENCE; PATTERNS; TRAUMA; LEVEL; LENKE AB Background: Spiral fractures of long bones have long been cited as indications of non-accidental trauma (NAT) in children; however, fracture types are only loosely defined in the literature, and intraobserver and interobserver variability in defining femoral fracture patterns is rarely mentioned. We sought to determine reliability in classifying femoral fractures in young children using a standard series of radiographs shown to physicians with varied backgrounds and training and to determine if a quantitative approach based on objective measurements made on plain radiographs could improve definition of these fractures. Methods: On 50 radiographs, the fracture ratio-fracture length divided by bone diameter-was determined and radiographs were reviewed by 14 observers, including pediatric orthopaedic surgeons, emergency room physicians, and musculoskeletal radiologists, who classified the fractures as transverse, oblique, or spiral. A second review of the images in a different order was carried out at least 10 days after the first. Results: Overall, intraobserver agreement was strong, whereas interobserver reliability was moderate. Experience level did not correlate with either result. Complete agreement among all observers occurred for only 5 fractures: 3 transverse and 2 spiral. An average fracture ratio near 1.0 appeared to be predictiveof a transverse fracture and a ratio of > 3.0, a spiral fracture; ratios between these 2 values resulted in essentially random classification. Conclusions: The ability to reproducibly classify femoral fractures in young children is highly variable among physicians of different specialties. These results support the belief that fracture morphology has little predictive value in NAT because of the wide variability in what observers classify as a spiral fracture of the femur. Caution should be used in the use of descriptive terms such as spiral, oblique, or transverse when classifying femoral fractures, as well as when evaluating children for possible NAT, because of the variability in classification. Level of Evidence: Level III-diagnostic study.

TI Endovascular Skills for Trauma and Resuscitative Surgery (ESTARS) course: Curriculum development, content validation, and program assessment SO JOURNAL OF TRAUMA AND ACUTE CARE SURGERY LA English DT Article DE Endovascular; trauma; hemorrhage; resuscitation; aortic balloon occlusion ID NONCOMPRESSIBLE TORSO HEMORRHAGE; AORTIC BALLOON OCCLUSION; CHANGING LANDSCAPE; VASCULAR TRAUMA; EVOLVING ROLE; MANAGEMENT; EPIDEMIOLOGY; SHOCK; INJURY; MODEL AB BACKGROUND The management of hemorrhage shock requires support of central aortic pressure including perfusion to the brain and heart as well as measures to control bleeding. Emerging endovascular techniques including resuscitative endovascular balloon occlusion of the aorta serve as potential lifesaving adjuncts in this setting. The Endovascular Skills for Trauma and Resuscitative Surgery (ESTARS) course was developed to provide fundamental endovascular training for trauma surgeons. METHODS ESTARS 2-day course incorporated pretest/posttest examinations, precourse materials, lectures, endovascular and open vascular instruments, Vascular Intervention System Trainer endovascular simulator, and live animal laboratories for training and testing. Curriculum included endovascular techniques for trauma; review of wires, sheaths, and catheters; as well as regional vascular injury management. Animal laboratories integrated arterial access, angiography, coil embolization, resuscitative endovascular balloon occlusion of the aorta, control of iliac artery injury, and vascular shunt placement. Students completed a knowledge test (precourse/postcourse) and a summative skills assessment. The test measured knowledge and judgment in vascular injury management as defined in the course objectives. Vascular Intervention System Trainer and animal laboratory were used for final examinations. Subjective performance was graded by expert observers using a global assessment scale and performance metrics. RESULTS Four pilot ESTARS courses were completed, with four participants each. Knowledge and performance significantly improved after ESTARS. Mean test examination scores increased by 77% to 85%, with a mean change of 9 percentage points [paired t (15) = 7.82, p < 0.0001]. The test was unidimensional (Cronbach's = 0.67). Technical skill significantly improved for both endovascular simulation and live animal laboratory examinations. All participants passed the live animal laboratory practical examination. CONCLUSION The ESTARS curriculum is effective at teaching a basic set of endovascular skills for resuscitation and hemorrhage control to trauma surgeons. ESTARS was confirmed as a stepwise and hierarchical curriculum demonstrating measurable improvements in performance metrics and should serve as a model for future competency-based structured training in endovascular trauma skills.

TI Strain Rate Effects in CFRP Used For Blast Mitigation SO POLYMERS LA English DT Article DE carbon fiber reinforced polymers; blast loads; reinforced concrete; strain rate; tensile strength ID CONCRETE SLABS; COMPOSITE-MATERIALS; FIBER; STRENGTH; BEHAVIOR AB The purpose of this research is to gain a better understanding of strain rate effects in carbon fiber reinforced polymer (CFRP) laminates exposed to blast loading. The use of CFRP offers an attractive option for mitigating structures exposed to blasts. However, the effect of high strain rates in CFRP composites commonly used in the civil industry is unknown. This research conducted tensile tests of 21 CFRP coupons using a hydraulically powered dynamic loader. The strain rates ranged from 0.0015 s(-1) to 7.86 s(-1) and are representative of strain rates that CFRP may see in a blast when used to strengthen reinforced concrete structures. The results of the testing showed no increase in the tensile strength or stiffness of the CFRP at the higher strain rates. In addition, the results showed significant scatter in the tensile strengths possibly due to the rate of loading or manufacture of the coupon.

Limited information is available about tick populations or pathogens in this area, and no data regarding frequency of tick bites or prevention measures among Gettysburg NMP employees are available. To address these gaps, ticks were collected, classified, and replaced (to minimize disruptions to tick populations) at two sites within Gettysburg NMP during April-September, 2009, among eight nonremoval samplings. On two additional occasions during May and June, 2009, ticks were collected and removed from the two original sites plus 10 additional sites and tested for tick-borne pathogens by using PCR. A self-administered anonymous survey of Gettysburg NMP employees was conducted to determine knowledge, attitudes, and practices regarding tick-borne diseases. Peak Ixodes scapularis nymph populations were observed during May-July. Of 115 I. scapularis ticks tested, 21% were infected with Borrelia burgdorferi, including 18% of 74 nymphs and 27% of 41 adults; no other pathogen was identified. The entomologic risk index was calculated at 1.3 infected nymphs/hour. An adult and nymph Amblyomma americanum were also found, representing the first confirmed field collection of this tick in Pennsylvania, but no pathogens were detected. The survey revealed that most park employees believed Lyme disease was a problem at Gettysburg NMP and that they frequently found ticks on their skin and clothing. However, use of personal preventive measures was inconsistent, and 6% of respondents reported contracting Lyme disease while employed at Gettysburg NMP. These findings indicate a need to improve surveillance for tick bites among employees and enhance prevention programs for park staff and visitors.

We survey state-of-the-art low-power CMOS building blocks as potential candidates for realizing such an architecture. For the critical analog-to-digital converter, we compare time-interleaved and frequency-interleaved architectures, including system-level simulations, and frequency-interleaving is shown to provide significant advantages. Measurement results from a 3.8 mW 5 GHz bandwidth analog domain frequency interleaver are presented to confirm the possibility of a very low-energy frequency domain digitizer. Coupled with DSP for calibration and signal feature extraction, this architecture has significant promise for cognitive spectrum sensing.

Continuing interest in finite body effects via image stresses has extended DD numerical approaches to improve the handling of surfaces. However, a physically accurate, yet computationally scalable, implementation has been elusive. This paper presents a new framework and implementation of a finite element-based discrete DD code that (1) treats arbitrarily shaped non-convex surfaces through image tractions, (2) allows for systematic refinement of the finite element mesh both in the bulk and on the surface and (3) provides a platform to scale to relatively larger and lengthier simulations. The approach is based on the capabilities of the Parallel Dislocation Simulator coupled through a distributed shared memory implementation for the calculation of large numbers of dislocation segments interacting with an independently large number of surface finite elements. Surface tracking approaches enable topological features at surfaces to be modeled. We verify the computed results via comparisons with analytical solutions for an infinite screw dislocation and prismatic loop near a surface and examine surface effects on a Frank-Read source. Convergence of the image force error with h- and p-refinement is shown to indicate the computational robustness. Additionally, through larger numerical experiments, we demonstrate the new capabilities in a three-dimensional elastic body of finite extent.

When compared with their civilian counterparts, military women are at a three-fold increased risk for suicide and, once they enter Veteran status, they are 79% more likely to die by suicide than civilian women. This article provides an overview of the problem of suicide among military women. Guidance on how to best assess and manage suicide risk among military women is provided. Providers are encouraged to adopt a bio-psychosocial approach and carefully evaluate each patient's traumatic life events, history of self-injurious behaviors with and without intention to die, postpartum depression, psychosis, relational problems, other psychiatric conditions, and/or occupational stressors. A series of clinical recommendations, such as implementing a safety plan, are discussed. Advances in epidemiologic and behavioral health research are needed to best understand the suicide risk assessment and treatment needs of military women.

TI Size-dependent enhancement of water relations during post-fire resprouting SO TREE PHYSIOLOGY LA English DT Article DE leaf area; leaf-specific whole-plant hydraulic conductance; mid-day leaf water potential; root hydraulic conductance; stem height; stomatal conductance ID NEOTROPICAL SAVANNA TREES; HYDRAULIC CONDUCTANCE; STOMATAL CONTROL; PRESCRIBED-FIRE; PONDEROSA PINE; PREDAWN PLANT; GAS-EXCHANGE; FINE-ROOT; GROWTH; SOIL AB In resprouting species, fire-induced topkill causes a reduction in height and leaf area without a comparable reduction in the size of the root system, which should lead to an increase in the efficiency of water transport after fire. However, large plants undergo a greater relative reduction in size, compared with small plants, so we hypothesized that this enhancement in hydraulic efficiency would be greatest among large growth forms. In the ecotone between long-leaf pine (Pinus palustris Mill.) savannas and wetlands, we measured stomatal conductance (g(s)), mid-day leaf water potential (Psi(leaf)), leaf-specific whole-plant hydraulic conductance (K-L.p), leaf area and height of 10 species covering a range of growth forms in burned and unburned sites. As predicted, K-L.p was higher in post-fire resprouts than in unburned plants, and the post-fire increase in K-L.p was positively related to plant size. Specifically, large-statured species tended to undergo the greatest relative reductions in leaf area and height, and correspondingly experienced the greatest increases in K-L.p. The post-fire increase in K-L.p was smaller than expected, however, due to a decrease in absolute root hydraulic conductance (i.e., not scaled to leaf area). The higher K-L.p in burned sites was manifested as an increase in gs rather than an increase in Psi(leaf). Post-fire increases in gs should promote high rates of photosynthesis for recovery of carbohydrate reserves and aboveground biomass, which is particularly important for large-statured species that require more time to recover their pre-fire size.

In conventional sparse kernel learning techniques, feature selection algorithms are optimal up to linear kernel because the contributions of individual features in the input space to the margin of the classifier can be determined explicitly for a linear kernel. But the use of nonlinear kernels leads to high dimensional, possibly infinite dimensional, Reproducing Kernel Hilbert Spaces (RKHS). Here, feature selection problem is highly combinatorial, and is NP-hard to solve because the number of all the possible combinations of the input features mapped from the input space into the RKHS is often prohibitively large to determine the contributions of subsets of features. To tackle this issue, in the proposed work, feature selection is explicitly and optimally performed in the EKFS instead of in the corresponding RKHS. Unlike the RKHS, the EKFS associated with any positive definite kernel including Gaussian RBF kernel can explicitly be built by using empirical kernel mapping. The feature selection in the EKFS has the same effect as the feature selection in the RKHS since both the EKFS and RKHS associated with same kernel have the same geometrical structure. The features in the EKFS are a kernel representation of each input vector with respect to all the training samples available. Thus, they represent nonlinear similarity measure of each data point with respect to reference samples with known labels. The proposed sparse kernel learning can optimally select multiple subsets of newly mapped features in the EKFS in order to improve the generalization performance of the classifier. The sparse kernel-based learning is tested on several hyperspectral datasets and a performance comparison among different feature selection techniques is presented.

TI Full-Scale Instrumented Testing and Three-Dimensional Modeling of Airfield Matting Systems SO INTERNATIONAL JOURNAL OF GEOMECHANICS LA English DT Article DE Full-scale tests; Instrumentation; Finite-element method; Three-dimensional analysis; Airport and airfield runways AB Matting systems are used for temporary applications on soft soils to reduce ground pressure exerted by aircraft, heavy equipment, vehicles, and construction material. They have been used for military airfields, construction platforms, and similar applications. Previous evaluation studies of matting systems have typically consisted of full-scale testing, with only a limited amount of numerical modeling found in the literature. This paper presents results of full-scale accelerated testing of 21 test sections encompassing five matting systems, five soil-support conditions, and two aircraft loadings. One of the soil-support conditions was instrumented and tested in conjunction with three matting systems and one aircraft loading. Three-dimensional finite-element modeling was performed on the instrumented sections using the measured test data for calibration. Good matches of measured soil stresses were obtained with the model for two of the mats, whereas the model underpredicted stresses in the third mat. Modeling of the type performed in this paper was capable of correctly ranking the performance of the matting systems modeled relative to the full-scale test results.

TI Prediction of High Incidence of Dengue in the Philippines SO PLOS NEGLECTED TROPICAL DISEASES LA English DT Article ID OUTBREAK DETECTION; FEVER; SURVEILLANCE; DISEASES; TRANSMISSION; TEMPERATURE; INFECTIONS; DYNAMICS; FOREST; VIRUS AB Background Accurate prediction of dengue incidence levels weeks in advance of an outbreak may reduce the morbidity and mortality associated with this neglected disease. Therefore, models were developed to predict high and low dengue incidence in order to provide timely forewarnings in the Philippines. Methods Model inputs were chosen based on studies indicating variables that may impact dengue incidence. The method first uses Fuzzy Association Rule Mining techniques to extract association rules from these historical epidemiological, environmental, and socio-economic data, as well as climate data indicating future weather patterns. Selection criteria were used to choose a subset of these rules for a classifier, thereby generating a Prediction Model. The models predicted high or low incidence of dengue in a Philippines province four weeks in advance. The threshold between high and low was determined relative to historical incidence data. Principal Findings Model accuracy is described by Positive Predictive Value (PPV), Negative Predictive Value (NPV), Sensitivity, and Specificity computed on test data not previously used to develop the model. Selecting a model using the F-0.5 measure, which gives PPV more importance than Sensitivity, gave these results: PPV = 0.780, NPV = 0.938, Sensitivity = 0.547, Specificity = 0.978. Using the F-3 measure, which gives Sensitivity more importance than PPV, the selected model had PPV = 0.778, NPV = 0.948, Sensitivity = 0.627, Specificity = 0.974. The decision as to which model has greater utility depends on how the predictions will be used in a particular situation. Conclusions This method builds prediction models for future dengue incidence in the Philippines and is capable of being modified for use in different situations; for diseases other than dengue; and for regions beyond the Philippines. The Philippines dengue prediction models predicted high or low incidence of dengue four weeks in advance of an outbreak with high accuracy, as measured by PPV, NPV, Sensitivity, and Specificity. Author Summary A largely automated methodology is described for creating models that use past and recent data to predict dengue incidence levels several weeks in advance for a specific time period and a geographic region that can be sub-national. The input data include historical and recent dengue incidence, socioeconomic factors, and remotely sensed variables related to weather, climate, and the environment. Among the climate variables are those known to indicate future weather patterns that may or may not be seasonal. The final prediction models adhere to these principles: 1) the data used must be available at the time the prediction is made (avoiding pitfalls made by studies that use recent data that, in actual practice, would not be available until after the date the prediction was made); and 2) the models are tested on data not used in their development (thereby avoiding overly optimistic measures of accuracy of the prediction). Local public health preferences for low numbers of false positives and negatives are taken into account. These models appear to be robust even when applied to nearby geographic regions that were not used in model development. The method may be applied to other vector borne and environmentally affected diseases.

We investigated the spatial dynamics of DENV-1, DENV-2 and DENV-3 in Brazil by applying a statistical framework to complete genome sequences. For all three serotypes, we estimated that the introduction of new lineages occurred within 7 to 10-year intervals. New lineages were most likely to be imported from the Caribbean region to the North and Northeast regions of Brazil, and then to disperse at a rate of approximately 0.5 km/day. Joint statistical analysis of evolutionary, epidemiological and ecological data indicates that aerial transportation of humans and/or vector mosquitoes, rather than Aedes aegypti infestation rates or geographical distances, determine dengue virus spread in Brazil. Author Summary Dengue virus serotypes are associated with millions of infections and thousands of deaths globally each year, primarily in tropical and subtropical regions. We investigated the spatial dynamics of DENV (serotypes 1-3) in Brazil by applying a statistical framework to complete genome sequences. Co-circulation of distinct genotypes, lineage extinction and replacement and multiple viral introduction events were found for all three serotypes. New lineages were typically introduced from the Caribbean into Northern Brazil and dispersed thereafter at a rate of approximate to 0.5 km/year. Our analysis indicates that aerial transportation is a more important determinant of viral dispersal than Aedes aegypti infestation rates or geographical distance. C1 [Nunes, Marcio R.

This includes broadband dielectric analysis, solid-state nuclear magnetic resonance (NMR), plate impact, and impulsive stimulated scattering. Dielectric relaxation measurements applicable at frequencies up to 10(6) Hz are useful for interpreting the high strain-rate deformation response; i.e. at the moment of target interaction with an accelerating impact or MHz stress wave excitation. Additionally, the capability of solid-state NMR to differentiate the microstructure-mediated segmental dynamics; correspondingly, the presence of a rigid phase (those in the phase-mixed regions) and a mobile phase associated with the soft-segment domains is demonstrated. These new insights not only further elucidate the microstructure details discerned through atomic force microscopy, but also enable the prediction of the macroscopically dynamic response in these model PUUs, particularly on the temporal scale over the range of mu s-ns.

It therefore follows that native microbial communication systems are a conspicuous target for developing engineered populations and networks. Quorum sensing (QS) is a highly conserved mechanism of bacterial cell-cell communication communication and QS-based synthetic signal transduction pathways represent a new generation of biotechnology toolbox members. Specifically, the E. coli QS master regulator, LsrR, is uniquely positioned to actuate gene expression in response to a QS signal. In order to expand the use of LsrR in synthetic biology, two novel LsrR switches were generated through directed evolution: an "enhanced" repression and derepression eLsrR and a reversed repression/derepression function "activator" aLsrR. Protein modeling and docking studies are presented to gain insight into the QS signal binding to these two evolved proteins and their newly acquired functionality. We demonstrated the use of the aLsrR switch using a coculture system in which a QS signal, produced by one bacterial strain, is used to inhibit gene expression via aLsrR in a different strain. These first ever AI-2 controlled synthetic switches allow gene expression from the lsr promoter to be tuned simultaneously in two distinct cell populations. This, work expands the tools available to create engineered microbial populations capable of carrying out complex functions necessary for, the development of advanced synthetic products.

TI Reproductive Hormone Influences on Thermoregulation in Women SO COMPREHENSIVE PHYSIOLOGY LA English DT Article ID SKIN BLOOD-FLOW; GANIRELIX ANTAGON/ORGALUTRAN-ASTERISK; ACTIVE CUTANEOUS VASODILATION; HEALTHY FEMALE VOLUNTEERS; HUMAN MENSTRUAL-CYCLE; UP HERS-II; REFLEX CONTROL; PHARMACODYNAMIC CHARACTERISTICS; ESTROGEN/PROGESTIN REPLACEMENT; THERMOEFFECTOR RESPONSES AB The present discussion reviews current knowledge regarding influences of the primary reproductive hormones on mechanisms of thermoregulatory control in women. The human body is remarkably capable of maintaining body temperature within a few tenths of a degree of normal (37 degrees C) over a wide range of activity and environmental exposures; this regulation is accomplished via integration of central and peripheral thermal information at the preoptic area of the anterior hypothalamus (PO/AH). We describe both central and peripheral mechanisms involved in controlling thermoregulation in humans, and how these mechanisms are affected by sex and hormone exposure. Estrogens generally promote vasodilation, heat dissipation, and lower body temperature and progesterone or progestins generally have the opposite effect. Estrogens and progesterone/progestins can also interact with androgens; this is an important point because androgens in the body can increase in both older and younger women. The study of reproductive hormone (estrogens, progesterone, luteinizing, and follicle stimulating hormones) effects on body systems is challenging because of the complex and multifaceted influences of these hormones, both individually and in combination. Thus, a number of methods to alter hormone exposure are explained in this article. We conclude that men and women do not exhibit major quantitative differences in physiological thermoregulatory responses to exercise and/or body heating when factors such as fitness and body size are taken into account. However, female and male reproductive hormones have important influences that can significantly alter individual thermoregulatory responses at various points throughout the lifespan.

In the present article, we review the physiology of sympathetic neural control of cardiovascular function with a focus on integrative mechanisms in humans. Direct measurement of sympathetic neural activity (SNA) in humans can be accomplished using microneurography, most commonly performed in the peroneal (fibular) nerve. In humans, muscle SNA (MSNA) is composed of vasoconstrictor fibers; its best-recognized characteristic is its participation in transient, moment-to-moment control of arterial blood pressure via the arterial baroreflex. This property of MSNA contributes to its typical "bursting" pattern which is strongly linked to the cardiac cycle. Recent evidence suggests that sympathetic neural mechanisms and the baroreflex have important roles in the long term control of blood pressure as well. One of the striking characteristics of MSNA is its large interindividual variability. However, in young, normotensive humans, higher MSNA is not linked to higher blood pressure due to balancing influences of other cardiovascular variables. In men, an inverse relationship between MSNA and cardiac output is a major factor in this balance, whereas in women, beta-adrenergic vasodilation offsets the vasoconstrictor/pressor effects of higher MSNA. As people get older (and in people with hypertension) higher MSNA is more likely to be linked to higher blood pressure. Skin SNA (SSNA) can also be measured in humans, although interpretation of SSNA signals is complicated by multiple types of neurons involved (vasoconstrictor, vasodilator, sudomotor and pilomotor). In addition to blood pressure regulation, the sympathetic nervous system contributes to cardiovascular regulation during numerous other reflexes, including those involved in exercise, thermoregulation, chemoreflex regulation, and responses to mental stress.

TI Annular Slot Loaded High-Impedance Ground Plane SO IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION LA English DT Article DE High-impedance ground plane; low-profile antenna ID ANTENNA AB High-impedance surfaces like electromagnetic band gap (EBG) ground planes have been used to realize low profile antennas. In this paper, an alternative ground plane design is presented for antennas with circular current distributions, which consists of an annular slot backed by a thin grounded substrate. The slot ring generates a high-impedance condition at a resonant frequency in the vicinity of the slot. This annular slot loaded ground plane results in efficient radiation of the low profile antenna in the broadside direction. Since the slot loaded ground plane consists of a single slot ring rather than periodic structures, it is much simpler to construct than the standard EBG ground plane. Numerical simulations and experimental measurements are shown to validate the design concept and are compared with a mushroom-type EBG ground plane. A parametric analysis was also conducted by varying the slot ring's dimensions and tuning varactors are shown to vary the ground plane's resonant frequency.

There is a lack of research that evaluates the ability of different solvents to soften MTA-based sealers during retreatment. This study tested the ability of 4 commonly used endodontic solvents to soften gutta-percha and MTA Fillapex to allow for the re-establishment of apical patency. Methods: Eighty-six extracted maxillary anterior teeth were instrumented to the working length to a size 45 (.04 taper size). Teeth were divided into 2 groups (n = 43 for each group). MTA Fillapex was placed into all canals. Group 1 was obturated with gutta-percha to the working length, and group 2 was obturated 2 mm short of the working length to ensure the apical 2 mm was filled with sealer only. Both groups were divided into 4 subgroups (n = 10). The remaining teeth served as the control group. Each subgroup was exposed to 1 of the following solvents: chloroform; Endosolv R (Septodont, Saint-Maur, France), Endosolv E (Septodont), or eucalyptol. Results: Patency was re-established in 100% of the teeth in groups 1 and,2 when tested with chloroform or Endosolv E, 80% of the teeth in group 1 and 90% in group 2 when tested with eucalyptol, and 10% of the teeth in group 1 and 50% in group 2 tested when with Endosolv R. The chi-square test indicated there was a statistical difference between Endosolv R and the other tested solvents for both groups. Conclusions: Chloroform, Endosolv E, and Eucalyptol soften GP and MTA Fillapex sufficiently to aid in re-establishing apical patency during endodontic retreatment.

Materials and Methods: We identified 2,608 patients with localized renal cell carcinoma who were treated surgically between 1995 and 2010 at our tertiary referral center. Competing risks Cox proportional hazards models were used to evaluate the relationship between statin use and time to local recurrence or progression (metastases or death from renal cell carcinoma) and overall survival. Statin use was modeled as a time dependent covariate as a sensitivity analysis. Models were adjusted for clinical and demographic features. Results: Of 2,608 patients 699 (27%) were statin users at surgery. Statin users had similar pathological characteristics compared to nonusers. At a median followup of 36 months there were 247 progression events. Statin use was associated with a 33% reduction in the risk of progression after surgery (HR 0.67, 95% CI 0.47-0.96, p = 0.028) and an 11% reduction in overall mortality that was not significant (HR 0.89, 95% CI 0.71-1.13, p = 0.3). Modeling statin use as a time dependent covariate attenuated the risk reduction in progression to 23% (HR 0.77, p = 0.12) and augmented the risk reduction in overall survival (HR 0.71, p = 0.002). Conclusions: In our cohort statin use was associated with a reduced risk of progression and overall mortality, although this effect was sensitive to the method of analysis. If validated in other cohorts, this finding warrants consideration of prospective research on statins in the adjuvant setting. C1 [Hamilton, Robert J.; Bernstein, Melanie; Hakimi, A.

Clausius-Clapeyron relationships were assumed for each case and the vapor pressures were estimated from the Langmuir equation over an appropriate temperature range just below substance melting/decomposition points. For vapor pressures extrapolated to room temperature, the rank with respect to decreasing volatility was found to be: DNAN>IMX-104>IMX-101>NQ>RDX>NTO. Interestingly, vapor pressure depression is observed in IMX formulations, where the formulation has a lower vapor pressure than its most volatile component, DNAN. The enthalpy of sublimation was determined for each substance and formulation from Clausius-Clapeyron equations generated by analysis of the thermogravimetric data. The general trends in vapor pressures and sublimation enthalpies associated with the component materials were in good agreement with previous experimental and computational results. The results obtained by this study have importance for future investigations of IMX, specifically for chemical detection and assessment of environmental fate.

TI Energetic Residues from the Detonation of IMX-104 Insensitive Munitions SO PROPELLANTS EXPLOSIVES PYROTECHNICS LA English DT Article DE Insensitive munitions; Detonation residues; IMX-104; NTO; Environment ID DEPOSITION RATES AB The development of insensitive munitions by NATO countries is an ongoing effort. Less-sensitive ingredients in both explosives and propellants will ensure the protection of deployed troops against an unwanted reaction to an external stimulus on the munitions stockpile. In the US Army, current efforts are directed towards the development of melt cast insensitive explosive formulations. Various formulations, mainly based on DNAN and NTO, have been developed and are now being fielded. Our research goal is to measure the deposition rate of energetics compounds from various insensitive munitions detonation scenarios. Our hypothesis is that the relative insensitiveness of these formulations leads to slightly higher deposition rates than conventional explosive formulations. This paper describes detonation residues research on mortar rounds containing IMX-104 explosive. Analyses indicate that high-order detonation residues are slightly greater for this formulation than for conventional munitions. However, blow-in-place detonations (BIPs) resulted in much higher residues deposition, indicating that a larger donor charge is required for efficient detonation. The highly soluble compound NTO was particularly problematic, with BIP deposition approaching 95% of the original load. Toxicological studies of NTO are not finalized, leaving considerable uncertainty regarding the feasibility of approving these rounds for distribution.

Raw water quality and its potential for effective removal were characterized by the specific ultraviolet absorbance (SUVA) components of absorbance of ultraviolet light at 254 nm wavelength (UV254) and dissolved organic carbon (DOC). The results demonstrate that, for the source water qualities tested (hydrophobic SUVA with moderate DOC content, 2.0 to 4.8 L/(mg.m) and 4.1 to 6.3 mg DOC/L), there was a tendency to produce a higher percentage of total trihalomethane (TTHM) over the five regulated species of haloacetic acid (HAA5). The treatment sequence and chemical selection play a critical role in the ability of a small community system operator to achieve compliance with the concentration of regulated disinfection by-products. For the waters tested ferric chloride coagulants perform better at reducing the higher molecular weight, hydrophobic organic precursors. Powdered activated carbon does not perform as well with these source waters unless its application is followed by a clarification process that effectively forms a sludge blanket. This research provides additional criteria for linking source water quality with treatment sequence for sustainable management of disinfection by-product (DBP) compliance. C1 [Roberts, C.

TI Fiberwalk: a random walk approach to fiber representative volume element creation SO ACTA MECHANICA LA English DT Article; Proceedings Paper CT Prager Medal Symposium in honor of George Weng CY JUL 28-31, 2013 CL Providence, RI SP Soc Engn Sci, Brown Univ, ASME, Appl Mech Div ID PACKING ALGORITHM; PARTICLES; COMPOSITES; MODEL AB Attaining accurate representative geometry for a finite element analysis at various scales can be a challenging research task. Added complications arise when the geometry is representing a manufactured or biological composite. In this study, a representative geometry of linear fibrous composites was created at the microscale and is employed to reproduce crystalline microfibril stacking of Kevlar to form a single fibril joined by a non-ordered crystal structure. The structure can have ellipsoidal or rectangular microfibrils stacked in ellipsoidal or rectangular fibrils and may have any desired packing ratio within the 1-100% range. In order to build a fibrous structure along a path, a Random Walk methodology was used. Since the directionality of the fibers is random, but always stepping from one side of the path toward the other, the fibers can wind around each other and tangle or terminate if needed. Another key concept of this method is the addition of a rotation matrix operation for the path of the fibers. This allows the path around the three local coordinates to be in a linear or sinusoidal direction. The resultant geometry produced can represent the tortuous path nanofibrils undergo. Moreover, rotation about the path axis allows for the twisted geometry of ring spun yarn, and metal cable to be reproduced. Inclusion of spherical objects to the path of the fibers has been accommodated to reproduce fiber projection around, or end at, an obstruction in their path. This approach allows representing impurities at the fibril, fiber, or yarn level of composite fabric manufacturing.

More than two decades of ongoing conflicts have degraded its healthcare system. A broad range of tropical diseases, along with opportunities for collaborative medical engagements (CMEs), are prevalent. However, reports from such events in this country are sparse. In June 2013, a CME was conducted in the western town of Muanda. Twenty-two hours of didactic sessions were collaboratively presented, and 158 patients were collaboratively evaluated. Durable dental and respiratory equipment, infrastructure improvements, and training opportunities were the top needs identified by the providers. Whether the regional referral hospital received sustainable benefit remains under investigation. However, the approach and needs assessment described herein provide a framework for future engagements or assistance. This CME established a precedence of medical partnership in the region because it led to the largest multidisciplinary joint collaboration in the history of the Democratic Republic of the Congo.

TI Three Enzymatically Active Neurotoxins of Clostridium botulinum Strain Af84: BoNT/A2, /F4, and /F5 SO ANALYTICAL CHEMISTRY LA English DT Article ID TOXIN PROTEOMICS; ENDOPEP-MS; SEROTYPE-A; SNAP-25; IDENTIFICATION; CLEAVAGE; GROWTH; PH; VAMP/SYNAPTOBREVIN; PROTEOLYSIS AB Botulinum neurotoxins (BoNTs) are produced by various species of clostridia and are potent neurotoxins which cause the disease botulism, by cleaving proteins needed for successful nerve transmission. There are currently seven confirmed serotypes of BoNTs, labeled A-G, and toxin-producing clostridia typically only produce one serotype of BoNT. There are a few strains (bivalent strains) which are known to produce more than one serotype of BoNT, producing either both BoNT/A and /B, BoNT/A and /F, or BoNT/B and /F, designated as Ab, Ba, Af, or BE Recently, it was reported that Clostridium botulinum strain Af84 has three neurotoxin gene clusters: bont/A2, bont/F4, and bont/F5. This was the first report of a clostridial organism containing more than two neurotoxin gene clusters. Using a mass spectrometry based proteomics approach, we report here that all three neurotoxins, BoNT/A2, /F4, and /F5, are produced by C. botulinum Af84. Label free MSE quantification of the three toxins indicated that toxin composition is 88% BoNT/A2, 1% BoNT/F4, and 11% BoNT/F5. The enzymatic activity of all three neurotoxins was assessed by examining the enzymatic activity of the neurotoxins upon peptide substrates, which mimic the toxins' natural targets, and monitoring cleavage of the substrates by mass spectrometry. We determined that all three neurotoxins are enzymatically active. This is the first report of three enzymatically active neurotoxins produced in a single strain of Clostridium botulinum.

Despite the variety of SA options, the output of resident presentations and publications remains disappointingly low, and many residents voice frustration with fulfilling the research requirements. A resident-driven process improvement project was undertaken with the goal of achieving a 100% increase of peer-reviewed publications and scholarly presentations by residents with secondary goals of doubling the involvement of staff, residents, and visiting medical or physician assistant students. METHODS: This project involves (1) increasing awareness of conferences for scholarly submission, (2) assignment of residents in a resident research team to lead efforts, (3) pairing of interns/students with senior mentors with similar interests, (4) faculty to include one resident on all projects, and (5) monthly SA meetings to track research progress, share ideas, and troubleshoot areas of difficulty. Scholarly totals were compared between the 2011-2012 and 2012-2013 academic years. RESULTS: The SA goals were achieved on all fronts. The number of resident presentations increased from three to 28 (seven regional, 10 national, and 11 international presentations), and resident peer-reviewed publications increased from two to six when compared to the previous year. Scholarly participation doubled at all levels. CONCLUSIONS: The authors recommend that other residencies consider promoting increased resident-to-resident scholarly mentorship, early planning with scheduled timeline, and increasing awareness of SA opportunities yearly.

The substrates were an intentionally doped and a UID freestanding hydride vapor phase epitaxy substrate, an MOCVD GaN template grown on a sapphire wafer, and a bulk GaN substrate grown via an ammonothermal method. Capacitance-voltage (C-V) results showed the carrier concentration was similar to 2 x 10(16) cm(-3) for films grown on each of the four substrates. With that doping level, the theoretical breakdown voltage (V (b)) is similar to 1600 V. However, measured V (b) for the devices tested on each of the four substrates fell short of this value. Also, the breakdown voltages across each of the four substrates were not substantially different. This result was especially surprising for films grown on bulk GaN substrates, because of their superior crystal quality, as determined from their x-ray rocking curve widths. Simple probability calculations showed that most of the diodes tested on the bulk substrate did not cover a single threading dislocation. Although optimization of edge-termination schemes is likely to improve V (b), we believe that point defects, not threading dislocations, are the main reason for the reduced performance of these devices.

The aim of the study was to determine the temporal expression of genes involved in early biofilm formation and eDNA production. We used qPCR to investigate expression of agrB, which is associated with secreted virulence factors and biofilm dispersal, cidA, which is associated with biofilm adherence and genomic DNA release, and alsS, which is associated with cell lysis, eDNA release and acid tolerance. The contribution of eDNA to the stability of the biofilm matrix was assessed by digesting with DNase I (Pulmozyme) and quantifying structure by confocal microscopy and comstat image analysis. AgrB expression initially increased at 24h but then dramatically decreased at 72h in an inverse relationship to biomass, supporting its role in regulating biofilm dispersal. cidA and alsS expression steadily increased over 72h, suggesting that eDNA was an important component of early biofilm development. DNase I had no effect on biomass, but did cause the biofilms to become more heterogeneous. Carbohydrates in the matrix appeared to play an important role in structural stability.

However, angular momentum has not been investigated during stair walking, which is an activity that presents a biomechanical challenge for balance-impaired populations. We investigated three-dimensional whole-body angular momentum during stair ascent and descent and compared it to level walking. Three-dimensional body-segment kinematic and ground reaction force (GRF) data were collected from 30 healthy subjects. Angular momentum was calculated using a 13-segment whole-body model. GRFs, externalmoment arms and net joint moments were used to interpret the angular momentum results. The range of frontal plane angular momentum was greater for stair ascent relative to level walking. In the transverse and sagittal planes, the range of angular momentum was smaller in stair ascent and descent relative to level walking. Significant differences were also found in the ground reaction forces, external moment arms and net joint moments. The sagittal plane angular momentum results suggest that individuals alter angular momentum to effectively counteract potential trips during stair ascent, and reduce the range of angular momentum to avoid falling forward during stair descent. Further, significant differences in joint moments suggest potential neuromuscular mechanisms that account for the differences in angular momentum between walking conditions. These results provide a baseline for comparison to impaired populations that have difficulty maintaining dynamic balance, particularly during stair ascent and descent. (C) 2014 Elsevier B.V.

Asymmetric predictors for humor appreciation and humor production SO JOURNAL OF RESEARCH IN PERSONALITY LA English DT Article DE Humor appreciation; Humor production; Motivation; Personality ID SENSE; PERSONALITY; DIMENSIONS; INTELLIGENCE; COMPETENCE; VALIDATION; ABILITY; TRAITS; STYLES; MODEL AB A "sense of humor" can be fractionated into appreciation (enjoying jokes), production fluency (making jokes), and production success (making funny jokes). There is scant research on how appreciation and production relate, and their relation to individual differences. Participants (N = 159) rated the humor of captioned cartoons and created captions for different cartoons. People who wrote funnier captions were less amused by the professionally-captioned cartoons. Production fluency, in contrast, was not related to appreciation. Personality predicted humor appreciation, but not production success. Demographics predicted production success, but not appreciation. Appreciation and production success appear to rely on separable mechanisms and motivations. Our results were also inconsistent with the idea that humor creators are motivated by dominance and humor appreciators by affiliation. (C) 2013 Elsevier Inc. All rights reserved.

TI Generalized stacking fault energy, ideal strength and twinnability of dilute Mg-based alloys: A first-principles study of shear deformation SO ACTA MATERIALIA LA English DT Article DE Stacking and twin fault energies; Twin propensity; Ideal shear strength; First-principles calculations; Pure alias shear deformation ID DENSITY-FUNCTIONAL THEORY; CROSS-SLIP STRESS; MAGNESIUM ALLOYS; HIGH-TEMPERATURE; SOLID-SOLUTION; GRADIENT APPROXIMATION; INCIPIENT PLASTICITY; AB-INITIO; METALS; ALUMINUM AB In an effort to establish a scientific foundation for the computational development of advanced Mg-based alloys, a systematic study of the generalized stacking fault (GSF) energy curves has been undertaken. Additionally, the associated stable and unstable stacking and twinning fault energies, ideal shear strengths, and comparative twinnability have been investigated in terms of first-principles calculations for dilute Mg-based alloys of type Mg95X. These GSF properties are predicted using the simple and especially the pure alias shear deformations on the basal (0 0 0 1) plane and along the [1 0 1 0] direction of the hexagonal close-packed (hcp) lattice. Fourteen alloying elements (X) are considered herein, namely Al, Ca, Cu, La, Li, Mn, Sc, Si, Sn, Sr, Ti, Y, Zn and Zr. The following conclusions are obtained: (i) the fault energies and the ideal shear strengths of Mg95X alloys decrease approximately linearly with an increasing equilibrium volume of X (or Mg95X), with the exceptions being for alloying elements Al, Cu, Si and Zn; (ii) alloying elements Sr and La greatly increase the twin propensity of hcp Mg, while Mn, Ti and Zr exhibit opposite trends; and (iii) the observed variation in GSF properties for hcp Mg caused by alloying elements X can be directly traced to the distribution of the differential charge density (triangle p) a spherical distribution of triangle p facilitates the redistribution of charge and shear deformation, resulting in lower shear-related properties, such as stacking fault energy and ideal shear strength. Computed GSF properties of Mg95X are shown to agree with available experimental and other theoretical results in the literature. (c) 2013 Acta Materialia Inc Published by Elsevier Ltd.

TI A computational approach to determining CVBEM approximate boundaries SO ENGINEERING ANALYSIS WITH BOUNDARY ELEMENTS LA English DT Article DE Cauchy integral; Complex variables; Collocation; Dirichlet; Approximate boundary; Complex variable boundary element method (CVBEM) ID FUNDAMENTAL-SOLUTIONS AB The complex variable boundary element method (CVBEM) provides solutions of partial differential equations of the Laplace and Poisson type. Because the CVBEM is based upon convex combinations from a basis set of functions that are analytic throughout the problem domain, boundary, and exterior of the problem domain union boundary (except along branch cuts), both the real and imaginary parts of the CVBEM approximations satisfy the Laplace equation, leaving the modeling error reduction effort to be that of fitting the problem boundary conditions. In this paper, the approximate boundary approach is used to depict the goodness of fit between the CVBEM results and the problem boundary conditions. The approximate boundary is the locus of points where the CVBEM approximation function meets the values of the problem boundary conditions. Because of the collocation method, the approximate boundary necessarily intersects the problem boundary at least at the collocation points specified on the problem boundary. Consequently, adding nodes and collocation points on the problem boundary results in reducing the departure between the approximate boundary and the true problem boundary. Thus, the approximate boundary is developed by tracking level curves from the real and/or imaginary parts of the CVBEM approximation function. Published by Elsevier Ltd.

TI Knee Extension and Stiffness in Osteoarthritic and Normal Knees: A Videofluoroscopic Analysis of the Effect of a Single Session of Manual Therapy SO JOURNAL OF ORTHOPAEDIC & SPORTS PHYSICAL THERAPY LA English DT Article DE manipulation; mobilization; osteoarthritis; stiffness ID JOINT STIFFNESS; RHEUMATIC CONDITIONS; COX-2 INHIBITORS; PHYSICAL-THERAPY; EXERCISE THERAPY; LEG STIFFNESS; UNITED-STATES; IN-VIVO; PREVALENCE; HIP AB STUDY DESIGN: Descriptive biomechanical study using an experimental repeated-measures design. OBJECTIVE: To quantify the response of participants with and without knee osteoarthritis (OA) to a single session of manual physical therapy. The intervention consisted primarily of joint mobilization techniques, supplemented by exercises, aiming to improve knee extension. (D BACKGROUND: While manual therapy benefits patients with knee OA, there is limited research quantifying the effects of a manual therapy treatment session on either motion or stiffness of osteoarthritic and normal knees. METHODS: The study included 5 participants with knee OA and 5 age-, gender-, and body mass index-matched healthy volunteers. Knee extension motion and stiffness were measured with videofluoroscopy before and after a 30-minute manual therapy treatment session. Analysis of variance and intraclass correlation coefficients were used to analyze the data. RESULTS: Participants with knee OA had restricted knee extension range of motion at baseline, in contrast to the participants with normal knees, who had full knee extension. After the therapy session, there was a significant increase in knee motion in participants with knee OA (P =.004) but not in those with normal knees (P =.201). For stiffness data, there was no main effect for time (P =.903) or load (P =.274), but there was a main effect of group (P =.012), with the participants with healthy knees having greater stiffness than those with knee OA. Reliability, using intraclass correlation coefficient model 3,3, for knee angle measurements between imaging sessions for all loading conditions was 0.99. Reliability (intraclass correlation coefficient model 3,1) for intraimage measurements was 0.97. CONCLUSION: End-range knee extension stiffness was greater in the participants with normal knees than those with knee OA. The combination of lesser stiffness and lack of motion in those with knee OA, which may indicate the potential for improvement, may explain why increased knee extension angle was observed following a single session of manual therapy in the participants with knee OA but not in those with normal knees. Videofluoroscopy of the knee appears reliable and relevant for future studies attempting to quantify the underlying mechanisms of manual therapy.

Jump-landing differences between varsity, club, and intramural athletes: The jump-ACL study. J Strength Cond Res 28(4): 1164-1171, 2014-Abnormal movement patterns have been identified as important prospective risk factors for lower extremity injury, including anterior cruciate ligament injury. Specifically, poor neuromuscular control during the early landing phase has been associated with increased injury risk. Although it is commonly assumed that higher division collegiate athletes generally exhibit better movement patterns than lower division athletes, few studies compare the biomechanical differences on basic tasks such as jump landing between various levels of athletic groups. The objective of this study was to evaluate jump-landing and fitness differences among college-aged Intramural, Competitive Club, and National Collegiate Athletic Association (NCAA) Division I level athletes. Two hundred seventy-seven student-athletes (222 men, 55 women; age 19.3 +/- 0.8 years) categorized as NCAA Division I, Competitive Club, or Intramural level athletes were evaluated during a jump-landing task using the Landing Error Scoring System (LESS), a validated qualitative movement assessment. Fitness was measured using the Army Physical Fitness Test (APFT). Results showed no significant differences in landing errors between the levels of athletic group (F-2,F-267 = 0.36, p = 0.70). There was a significant difference in landing errors between genders (F-1,F-268 = 3.99, p = 0.05). Significant differences in APFT scores were observed between level of athletic group (F-2,F-267 = 11.14, p < 0.001) and gender (F-1,F-268 = 9.27, p = 0.003). There was no significant correlation between the APFT and LESS scores (p = 0.26). In conclusion, higher level athletes had better physical fitness as measured by the APFT but did not as a group exhibit better landing technique. The implications of this research suggest that "high-risk" movement patterns are prevalent in all levels of athletes. C1 [Theiss, Justin L.; Gerber, J.

These functions make glycans attractive molecules for stimulating repair of the injured nervous system. Yet, glycans are often difficult to synthesize or isolate and have the disadvantage to be unstable in a complex tissue environment. To circumvent these issues, we have screened a library of small organic compounds to search for structural and functional mimetics of the neurostimulatory glycan polysialic acid (PSA) and identified the 5-HT4 receptor agonist tegaserod as a PSA mimetic. The PSA mimicking activity of tegaserod was shown in cultures of central and peripheral nervous system cells of the mouse and found to be independent of its described function as a serotonin (5-HT4) receptor agonist. In an in vivo model for peripheral nerve regeneration, mice receiving tegaserod at the site of injury showed enhanced recovery compared to control mice receiving vehicle control as evidenced by functional measurements and histology. These data indicate that tegaserod could be repurposed for treatment of nervous system injuries and underscores the potential of using small molecules as mimetics of neurostimulatory glycans.

TI Quality of information-aware mobile applications SO PERVASIVE AND MOBILE COMPUTING LA English DT Article DE Quality of Information; QoI; Resource allocation; Networking framework; Tactical networks; Timeliness; Accuracy AB In this paper, we propose a framework for providing Quality of Information (QoI) aware networking. QoI quantifies how useful information is for a given application. Its value is comprised of both intrinsic and contextual attributes related to the information. Intrinsic attributes include freshness and accuracy of the information. Contextual metrics include completeness and timeliness. To design QoI-aware network control algorithms, such as resource control algorithms, attributes of data must be mapped to QoI. Then, network algorithms may deliver the data in such a way that the ultimate information derived from the data is of sufficient quality for its purpose. We propose our QoI framework, and present the concept of QoI functions that capture tradeoffs between different attributes of QoI. We use optical character recognition (OCR) as a model image processing application. We focus on two attributes of QoI for the OCR application: accuracy and timeliness. We show how network controls and data processing, such as error recovery and compression, operating on data, impact the QoI delivered to a recipient. We then show how reductions in the required QoI may have a drastic impact on the amount of network resources required to support a QoI-aware transaction. Our results are based on an implementation on Android phones. (C) 2013 Elsevier B. V. All rights reserved. C1 [Edwards, James; La Porta, Thomas F.] Penn State Univ, University Pk, PA 16802 USA.

TI Prevention of low back pain in the military cluster randomized trial: effects of brief psychosocial education on total and low back pain-related health care costs SO SPINE JOURNAL LA English DT Article DE Costs; Low back pain; Prevention; Biopsychosocial; Military ID CORE STABILIZATION EXERCISES; OPERATION IRAQI FREEDOM; LOST PRODUCTIVE TIME; MANAGEMENT; SOLDIERS; VALIDITY; POLM; INTERVENTION; NCT00373009; RELIABILITY AB BACKGROUND CONTEXT: Effective strategies for preventing low back pain (LBP) have remained elusive, despite annual direct health care costs exceeding $85 billion dollars annually. In our recently completed Prevention of Low Back Pain in the Military (POLM) trial, a brief psychosocial education program (PSEP) that reduced fear and threat of LBP reduced the incidence of health care-seeking for LBP. PURPOSE: The purpose of this cost analysis was to determine if soldiers who received psychosocial education experienced lower health care costs compared with soldiers who did not receive psychosocial education. STUDY DESIGN/SETTING: The POLM trial was a cluster randomized trial with four intervention arms and a 2-year follow-up. Consecutive subjects (n=4,295) entering a 16-week training program at Fort Sam Houston, TX, to become a combat medic in the U.S. Army were considered for participation. METHODS: In addition to an assigned exercise program, soldiers were cluster randomized to receive or not receive a brief psychosocial education program delivered in a group setting. The Military Health System Management Analysis and Reporting Tool was used to extract total and LBP-related health care costs associated with LBP incidence over a 2-year follow-up period. RESULTS: After adjusting for postrandomization differences between the groups, the median total LBP-related health care costs for soldiers who received PSEP and incurred LBP-related costs during the 2-year follow-up period were $26 per soldier lower than for those who did not receive PSEP ($60 vs. $86, respectively, p=.034). The adjusted median total health care costs for soldiers who received PSEP and incurred at least some health care costs during the 2-year follow-up period were estimated at $2 per soldier lower than for those who did not receive PSEP ($2,439 vs. $2,441, respectively, p=.242). The results from this analysis demonstrate that a brief psychosocial education program was only marginally effective in reducing LBP-related health care costs and was not effective in reducing total health care costs. Had the 1,995 soldiers in the PSEP group not received PSEP, we would estimate that 16.7% of them would incur an adjusted median LBP-related health care cost of $517 compared with the current 15.0% soldiers incurring an adjusted median cost of $399, which translates into an actual LBP-related health care cost savings of $52,846 during the POLM trial. However, it is likely that the unaccounted for direct and indirect costs might erase even these small cost savings. CONCLUSION: The results of this study will help to inform policy- and decision-making regarding the feasibility of implementing psychosocial education in military training environments across the services. It would be interesting to explore in future research whether cost savings from psychosocial education could be enhanced given a more individualized delivery method tailored to an individual's specific psychosocial risk factors.

PURPOSE: To determine the incidence rate and demographic risk factors of low back pain in an ethnically diverse and physically active population of US military vehicle operators. STUDY DESIGN/SETTING: Retrospective database analysis. PATIENT SAMPLE: All active-duty military service members between 1998 and 2006. OUTCOME MEASURES: Low back pain requiring visit to a health-care provider. METHODS: A query was performed using the US Defense Medical Epidemiology Database for the International Classification of Diseases, Ninth Revision, Clinical Modification code for low back pain (724.20). Multivariate Poisson regression analysis was used to estimate the rate of low back pain among military vehicle operators and control subjects per 1,000 person-years, while controlling for sex, race, rank, service, age, and marital status. RESULTS: A total of 8,447,167 person-years of data were investigated. The overall unadjusted low back pain incidence rate for military members whose occupation is vehicle operator was 54.2 per 1,000 person-years. Compared with service members with other occupations, motor vehicle operators had a significantly increased adjusted incidence rate ratio (IRR) for low back pain of 1.15 (95% confidence interval [CI] 1.13-1.17). Female motor vehicle operators, compared with males, had a significantly increased adjusted IRR for low back pain of 1.45 (95% CI 1.39-1.52). With senior enlisted as the referent category, the junior enlisted rank group of motor vehicle operators had a significantly increased adjusted IRR for low back pain: 1.60 (95% CI 1.52-1.70). Compared with Marine service members, those motor vehicle operators in both the Army, 2.74 (95% CI 2.60-2.89), and the Air Force, 1.98 (95% CI 1.84-2.14), had a significantly increased adjusted IRR for low back pain. The adjusted IRRs for the less than 20-year and more than 40-year age groups, compared with the 30- to 39-year age group, were 1.24 (1.15-1.36) and 1.23 (1.10-1.38), respectively. CONCLUSIONS: Motor vehicle operators have a small but statistically significantly increased rate of low back pain compared with matched control population. Published by Elsevier Inc.

Hero, Alfred O., III TI Collaborative 20 Questions for Target Localization SO IEEE TRANSACTIONS ON INFORMATION THEORY LA English DT Article DE Optimal query selection; machine-machine interaction; target localization; convergence rate; minimum entropy; human-aided decision making AB We consider the problem of 20 questions with noise for multiple players under the minimum entropy criterion in the setting of stochastic search, with application to target localization. Each player yields a noisy response to a binary query governed by a certain error probability. First, we propose a sequential policy for constructing questions that queries each player in sequence and refines the posterior of the target location. Second, we consider a joint policy that asks all players questions in parallel at each time instant and characterize the structure of the optimal policy for constructing the sequence of questions. This generalizes the single player probabilistic bisection method for stochastic search problems. Third, we prove an equivalence between the two schemes showing that, despite the fact that the sequential scheme has access to a more refined filtration, the joint scheme performs just as well on average. Fourth, we establish convergence rates of the mean-square error and derive error exponents. Finally, we obtain an extension to the case of unknown error probabilities. This framework provides a mathematical model for incorporating a human in the loop for active machine learning systems.

In the current study, codon-harmonized recombinant Pfs25 (CHrPfs25) was expressed in Escherichia coli, and purified protein after simple oxidative refolding steps retained reduction-sensitive conformational epitopes of transmission-blocking monoclonal antibodies. CHrPfs25 formulated in several adjuvants elicited strong immunogenicity in preclinical studies in mice. Antibodies elicited after immunization recognized native Pfs25 on the surface of live gametes of P. falciparum and demonstrated complete malaria transmission-blocking activity. The transmission-blocking efficacy was 100% even after a 1:128 dilution of sera from immunized mice in the complete Freund's adjuvant and Montanide ISA51 groups and after a 1:16 dilution of sera from mice in the alum group. The blocking was mediated by antibodies; purified IgG at concentrations as low as 31.25 mu g/ml exhibited 100% transmission blocking in membrane feeding assays employing two different species of mosquitoes, Anopheles gambiae and Anopheles stephensi. This study provides the first evidence for successful expression of biologically functional rPfs25 in E. coli. The extremely potent malaria transmission-blocking activity of antibodies elicited by immunization with purified protein provides strong support for further evaluation of E. coli-derived CHrPfs25 as a malaria transmission-blocking vaccine in human clinical trials.

This paper presents a simplified method to evaluate the increase in elastic buckling strength and corresponding unbraced length due to improved warping restraint provided by split pipe stiffeners located at the ends of doubly symmetric W-shapes. The solution is based on analytical studies and results from a finite-element parametric study validated using large-scale laboratory tests. The laboratory tests include specimens exposed to concentrated loads with split pipe warp-restraining devices and others with standard plate stiffeners. The proposed analytic method is based on uniform moment and shows that warping restraint can increase the elastic buckling capacity of a girder by 30-100%. The improved warping stiffness can result in increases in the unbraced length in the range of 20-35% compared with systems with plate stiffeners.

TI Reconceptualization and Optimization of a Rapidly Deployable Floating Causeway SO JOURNAL OF BRIDGE ENGINEERING LA English DT Article DE Military engineering; Bridges; Optimization; Floating structures; Composite material ID BRIDGE DECK; MULTIOBJECTIVE OPTIMIZATION; HEURISTIC OPTIMIZATION; DESIGN; ALGORITHMS AB There is an increasing demand for rapidly deployable causeways that can provide access from ship-to-shore for military and disaster relief operations. Existing systems have major limitations including only being transportable and emplaceable by large strategic sealift vessels, having high weight and packaged volumes, and requiring intensive on-site assembly. In response to the demand for a lightweight, air-liftable, quickly emplaceable causeway, the Engineer Research and Development Center (Vicksburg, Mississippi) developed a prototype comprised of aluminum modules joined by compliant connections and supported by pneumatic floats. As research and development progressed and experience was gained, eliminating the heavy and complex compliant connections was identified as a potential improvement. To eliminate these compliant connections, this paper shows how this design can be reconceptualized so a desired superstructure flexibility (that takes advantage of buoyancy while meeting deflection limits) is achieved. The superstructure has been designed for a target stiffness to permit a desired curvature under a design moment. This paper will review existing causeways, present this reconceptualization, and discuss the optimization implemented to achieve this new design.

The Military Amputation Database of all U. S. military amputations during the same 10-y period was also reviewed. Demographic data, injury characteristics, and outcomes were evaluated. Results: Among 26,634 subjects, 587 (2.2%) had a VTE. This number included 270 subjects (1.0%) with deep venous thrombosis (DVT), 223 (0.8%) with PE, and 94 (0.4%) with both DVT and PE. Lower extremity amputation was independently associated with PE (odds ratio [OR], 1.70; 95% confidence interval [CI], 1.07-2.69). A total of 1003 subjects suffered a lower extremity amputation, with 174 (17%) having a VTE. Of these, 75 subjects (7.5%) were having DVT, 70 (7.0%) were having PE, and 29 (2.9%) were found to have both a DVT and a PE. Risk factors found to be independently associated with VTE in amputees were multiple amputations (OR, 2; 95% CI, 1.35-3.42) and above the knee amputation (OR, 2.11; 95% CI, 1.3-3.32). Conclusions: Combat wounded are at a high risk for thromboembolic complications with the highest risk associated with multiple or above the knee amputations. Published by Elsevier Inc.

TI Increased sensitivity to physical activity among individuals with knee osteoarthritis: Relation to pain outcomes, psychological factors, and responses to quantitative sensory testing SO PAIN LA English DT Article DE Activity-related pain; Chronic pain; Depression; Knee osteoarthritis; Mechanical pain; Musculoskeletal pain; Pain catastrophizing; Pain threshold; Pain-related function; Physical activity; Psychological factors; Quantitative sensory testing; Sensitivity to physical activity; Temporal summation of pain ID QUALITY-OF-LIFE; CLINICAL-PRACTICE GUIDELINES; ACTIVITY-RELATED SUMMATION; SLOW TEMPORAL SUMMATION; FEAR-AVOIDANCE MODEL; FIBER-EVOKED PAIN; BACK-PAIN; CATASTROPHIZING SCALE; FIBROMYALGIA PATIENTS; CENTRAL SENSITIZATION AB Recent findings suggest that certain individuals with musculoskeletal pain conditions have increased sensitivity to physical activity ( SPA) and respond to activities of stable intensity with increasingly severe pain. This study aimed to determine the degree to which individuals with knee osteoarthritis (OA) show heightened SPA in response to a standardized walking task and whether SPA cross-sectionally predicts psychological factors, responses to quantitative sensory testing (QST), and different OA-related outcomes. One hundred seven adults with chronic knee OA completed self-report measures of pain, function, and psychological factors, underwent QST, and performed a 6-min walk test. Participants rated their discomfort levels throughout the walking task; an index of SPA was created by subtracting first ratings from peak ratings. Repeated-measure analysis of variance revealed that levels of discomfort significantly increased throughout the walking task. A series of hierarchical regression analyses determined that after controlling for significant covariates, psychological factors, and measures of mechanical pain sensitivity, individual variance in SPA predicted self-report pain and function and performance on the walking task. Analyses also revealed that both pain catastrophizing and the temporal summation of mechanical pain were significant predictors of SPA and that SPA mediated the relationship between catastrophizing and self- reported pain and physical function. The discussion addresses the potential processes contributing to SPA and the role it may play in predicting responses to different interventions for musculoskeletal pain conditions.

In this article, we use the discrete slip-link model to predict its linear and nonlinear rheology. Model parameters are obtained from the dynamic modulus data of pure solvent. Network rheology predictions also require an estimate of the fraction and architecture of dangling or inactive strands in the network, which is not directly measurable. The active strand fraction is estimated from dynamic modulus measurements, and the molecular weight is adjusted to fit the dynamic modulus data. Then, the nonlinear rheology can be predicted without adjustments. These successful predictions strongly suggest that the observed rheological modification in the swollen blend arises from the constraint dynamics between the network chains and the dangling ends.

In this study, we compared estimates of genetic diversity and patterns of population genetic structure in a rare cliff endemic, Erigeron lemmonii, to those of a widespread congener, E. arisolius. Our goals were to assess whether rarity and small population size have negatively affected levels of genetic diversity in E. lemmonii and to identify genetic threats that may limit the ability of E. lemmonii to persist. Levels of observed and expected heterozygosity and allelic richness in E. lemmonii were approximately 60 % of those found in E. arisolius. After correcting for null alleles, inbreeding coefficients in both species of Erigeron were very small, suggesting that both species are highly outcrossing and may demonstrate self-incompatibility. Patterns of genetic structure in both species revealed almost no population substructuring, indicating that widespread gene flow is occurring within each species. Because we found no evidence for inbreeding or a genetic bottleneck in E. lemmonii, it is likely that the species' lower genetic diversity may be the result of genetic drift. Because E. lemmoni exists in a single population, no other populations exist to bolster population size or genetic diversity in the event of declines; thus, conservation efforts should focus on seed collection from as many individuals as possible to protect against possible future losses of genetic diversity. We also recommend continued monitoring of both population size and genetic diversity in E. lemmonii to ensure the species' long-term persistence and viability.

The differential roles of complement receptor type 3 (CR3) and Dectin-1, the known beta-glucan receptors, and their associated signaling pathways in the generation of oxidative burst induced by different physical forms of Saccharomyces cerevisiae-derived beta-glucan were examined in human peripheral blood mononuclear cells (PBMC). In this study whole glucan particle (WGP) or immobilized soluble beta-glucan (ISG) was used to represent the phagocytizable or the nonphagocytizable form of a fungus, respectively. Oxidative burst as measured by the formation of superoxide (SO) was detected in PBMC in response to WGP and ISG. SO induction with WGP was concluded to be Dectin-1-mediated and required Src family kinases, phosphatidylinositol-3 kinase and protein kinase B/Akt. In contrast, the SO induction generated by ISG was CR3-mediated and required focal adhesion kinase, spleen tyrosine kinase, phosphatidylinositol-3 kinase, Akt, p38 mitogen activated protein kinase, phospholipase C and protein kinase C. The study results support the hypothesis that human PBMC, specifically monocytes, utilize distinct receptors and overlapping, but distinct, signaling pathways for the oxidative burst in response to challenge by different physical forms of beta-glucan.

The purpose of this research was to develop a reliable method for determining HRC continuously in real time in critically ill patients using multiple waveform channels that also compensates for noisy and unreliable data. Using simultaneously acquired electrocardiogram (Leads I, II, V) and arterial blood pressure waveforms sampled at 360 Hz from 250 patients (over 375 h of patient data), we evaluated a new data fusion framework for computing HRC in real time. The framework employs two algorithms as well as signal quality indices. HRC was calculated (via the method of sample entropy), and equivalence tests were then performed. Bland-Altman plots and box plots of differences between mean HRC values were also obtained. Finally, HRC differences were analyzed by paired t tests. The gold standard for obtaining true means was manual verification of R waves and subsequent entropy calculations. Equivalence tests between mean HRC values derived from manually verified sequences and those derived from automatically detected peaks showed that the "Fusion" values were the least statistically different from the gold standard. Furthermore, the fusion of waveform sources produced better error density distributions than those derived from individual waveforms. The data fusion framework was shown to provide in real-time a reliable continuously streamed HRC value, derived from multiple waveforms in the presence of noise and artifacts. This approach will be validated and tested for assessment of HRC in critically ill patients.

These effects are largest for high-ability proteegees. Junior officers who were exposed to multiple high-performing mentors did not experience an additional increase in promotion rates.

The investigation was performed as part of a larger effort to improve the design methodologies for reinforced masonry subjected to blast loading. The masonry walls were non-load-bearing and vertically spanning, which represents a significant amount of common construction in the United States. Both single-wythe and veneer wall sections were evaluated. Two types of concrete masonry units were used, i.e., conventional and A-block concrete masonry units. The results of the program provide a better understanding of the ultimate dynamic capacities and ductility of reinforced masonry wallsboth single-wythe and veneer wallswhich will ultimately help engineers produce designs that are safer and more economical.

Study Design Analysis of a national database for all US civil trials. Methods The Westlaw database was reviewed from 2001 to 2011. Data were compiled on the demographics of the plaintiffs, use of expert witnesses, procedures, nature of the injury, legal allegations, verdicts, and indemnities. Results One hundred ninety-eight cases met inclusion criteria. Verdicts for the defendant/otolaryngologist predominated (58%), whereas the average award when the verdict favored the plaintiff was $1,782,514. When otolaryngologists were used as expert witnesses by the defense, the verdict outcome statistically favored the defendant. Two of the most commonly cited legal allegations were improper performance and failure to diagnose and treat. Fifty-one cases involved allegations of wrongful death, with the overall outcome favoring the plaintiffs (51%). The average indemnities in these cases were significantly higher for plaintiff verdicts at $2,552,580 versus settlements at $992,896. Forty-two cases involved malignancy, with the two most common allegations being failure to diagnose and treat (79%) and delay in diagnosis (74%). Conclusions Our study reveals that in the past decade, in significant malpractice litigations, overall outcomes favored otolaryngologists. The average awards was significantly higher when cases involved malignancy. Our analysis reveals the importance of meticulous surgical techniques and thorough preoperative evaluations. Last, when otolaryngologists are defendants in litigation, our review reiterates the value of the otolaryngologist as the defense's expert witnesses.

TI Performance of synthetic jet fuels in a meso-scale heat recirculating combustor SO APPLIED ENERGY LA English DT Article DE Alternative fuel; JP-8; Microcombustion; Heat recirculating combustor; Flame stability; Combustion characteristics ID SURROGATE FUEL AB The performance of two synthetic aviation fuels was evaluated in a meso-scale heat recirculating combustor and the respective results compared with the combustion characteristics of a conventional petroleum-based jet fuel. One of the alternative jet fuels was synthesized via a Fischer-Tropsch (F-.T fuel) process, while the other was produced from tallow (bin-jet fuel). The petroleum-based fuel used in this study was JP-8. The combustion and extinction behavior of the above fuels and their mixtures (50% synthetic fuel and 50% JP-8 by volume in JP-8) in the meso-scale combustor using oxygen under fuel-rich and fuel-lean non-premixed combustion conditions was examined. The synthetic fuels exhibited stable combustion over a range of equivalence ratios at each fuel flow rate; however, stable combustion was not achieved for JP-8 under any of the examined conditions. The mixtures also exhibited somewhat unstable combustion phenomena as those seen with JP-8, but dampened enough such that mostly stable combustion could occur. Fuel characterization analysis was performed for each fuel, and their respective thermal performances evaluated. Both the F-T and bio-jet fuels reached a maximum thermal efficiency of about 95% near their respective rich extinction limits. The mixtures exhibited somewhat poor thermal performances, with a maximum thermal efficiency of about 75%. The results reveal that composition of the fuel plays a prominent role in the flame stability and thermal performance in meso-scale combustors, as more complex species (such as aromatics, found in JP-8) have a slower reaction rate than simple species. The short residence time available in the combustion zone of the micro-combustion chamber does not allow to fully combust the complex fuel species, resulting in flame instability and formation of soot.

The scales are calculated using sonic anemometer data from two elevations, 5 and 50 m above the ground at the main tower site of the CASES-99 field campaign. In general, none of these scales agrees with the other, although the scale of maximum TKE is often similar to the boundary-layer depth during daytime hours, and the length scales derived from anisotropy characteristics are sometimes similar to , and depending on scale definition and thermal stability. Except for the scale with the strictest isotropy threshold, the turbulence is anisotropic for each of the various candidates for the outer scale. Length scales for maximum buoyancy flux and temperature variance are evaluated and the turbulence characteristics at these scales are almost always found to be anisotropic.

TI Effect of resistance spot welding parameters on weld pool properties in a DP600 dual-phase steel: A parametric study using thermomechanically-coupled finite element analysis SO MATERIALS & DESIGN LA English DT Article ID 6061-T6 ALUMINUM-ALLOY; CONTACT CONDITIONS; SIMULATION; SIZE; TRANSFORMATIONS; MICROSTRUCTURE; SHEETS AB The objective of this research is to quantify the effects of resistance spot welding (RSW) parameters on different weld properties of a dual-phase steel. A finite element based model was used which accounted for the following required physical interactions: the interaction between (1) the electro-kinetics and heat transfer via the Joule effect, (2) the heat transfer and phase transformations through latent heat, and (3) the heat transfer, electro-kinetics, and mechanical behavior via the contact conditions. The effects of the RSW parameters on weld properties were investigated within a design of experiments framework by altering (1) the electrical current intensity, (2) the welding time, (3) the sheet thickness, (3) the electrode face radius, and (5) the squeeze force at multiple levels. The simulation results were analyzed using the analysis of variance (ANOVA) technique to show the effects of these parameters and their potential interactions, along with their significance. The current intensity was the most influential factor and resulted in an increased size of molten zone and the heat affected zone. The sheet thickness and welding time also showed significant contributions in changing the weld properties. The effects of the other parameters were less significant. The importance of this study is that finding the optimal process window for RSW parameters can help to engineer the desired weld properties. (C) 2013 Elsevier Ltd. All rights reserved.

An estimated 402 479 (95% confidence interval = 335 116-469 842) injuries associated with high chairs and chairs were treated in United States emergency departments, with an average of 9421 high chair-related injuries and 40 889 chair-related injuries annually. The number of high chair-related injuries significantly increased by 22.4% from 8926 injuries in 2003 to 10 930 injuries in 2010. Falling was the most common injury mechanism associated with high chairs (92.8%) and chairs (87.3%). Closed head injury was the most common diagnosis associated with high chairs (37.3%), and increased in number (P = .005) and rate (P = .006) from 2003 to 2010. Child caregivers should properly engage high chair safety restraint systems and encourage appropriate behaviors by young children when using chairs.

This sterile inflammatory response is believed to be, in part, associated with danger-associated molecular patterns (DAMPs). Mitochondrial DAMPs (MTDs) have been shown to be important in trauma-induced neutrophil activation, but it is unknown whether MTDs activate other innate immune cells, such as gamma delta T-cells. To study this, splenic CD3(+) gamma delta T-cells were isolated from alpha beta T-cell-deficient C57BL/6 mice and mitochondria isolated from wild type mouse livers. MTDs were isolated from mitochondria by sonication and centrifugation. Gamma delta T-cells were incubated with various concentrations of MTDs (0-500 mu g/ml) for 24 h. T-cells were phenotyped for TLR expression by flow cytometry and the supernatants assayed for cytokine and growth factor content. MTDs caused a dose-dependent increase in TLR2 and TLR4 expression by gamma delta T-cells. Both the percentage of cells positive for TLRs and the degree of expression increased. MTDs also induced the production of IL-1 beta, IL-6, IL-10, RANTES, fibroblast growth factor-basic and vascular endothelial growth factor by gamma delta T-cells. These findings support the concept that the MTDs released after tissue/cellular injury are capable of activating gamma delta T-cells, thus initiating sterile inflammation, as well as subsequent healing processes.

Our calculations are the first to show that adsorption of dissociated water changes the (110) surface structure. The characteristic III-V bond rotation through an angle of 30 is reversed. The buckled III-V bond at the semiconductor/water interface rotates into the surface through a new angle, which we calculate to be approximately 11 degrees on all three binaries. Only dissociation of water - as opposed to chemisorption or physisorption - leads to this pseudo-unrelaxed configuration. We calculate geometries and reaction energies for several different adsorption mechanisms and find that molecular adsorption is the most favorable. We are able to reproduce binding configurations and energies for known adsorption sites on GaAs(110), but we also show new calculations for water on GaSb(110) and InAs(110). Lastly, we calculate the shift in electronic work function and induced surface dipole moment due to adsorbed water. We show that shifts in work function maximize at 1 ML of water, consistent with previous experimental works. Analysis of the partial charges and electron density reveals that adsorption of water polarizes the (110) surface, leading to local charge transfer across the semiconductor/water interface.

The decrease in absorbance at 268 nm with the presence of dimethyl sulfoxide (DMSO) allows measurement of the ascorbate disappearance in the reaction with excess chlorite. The measured rate constant at 25 +/- 0.02 degrees C, 3.67 x 10(-4) M DMSO, ionic strength 0.51 M (NaClO4), and in the presence of 3.32 x 10(-9) M ethylenediaminetetraacetic acid is 13.81 +/- 1.30 M-1 s(-1). Rate constant measurements over the range 15-35 degrees C gave an Arrhenius activation energy of 75.51 +/- 4.53 kJ mol(-1). This result is the first reported determination of the kinetics of this reaction and is consistent with either electron- or oxygen-transfer mechanisms. Anomalously, reduction of chlorite results in its oxidation, because intermediate hypochlorite oxidizes chlorite.

The expression of NANOGP8 has been documented in several cancers and is related to cell proliferation and tumor development. However, the regulation of NANOGP8 expression has not been investigated. Therefore, the role of NANOGP8 in cell proliferation has not been completely understood. METHODSWe evaluate the expression of NANOG1 and NANOGP8 in prostate cancer cell lines and primary cultures of prostate tissues. We investigate clonogenicity, sphere formation, and xenograft tumor growth of prostate cancer cells with an activated 5flanking region of NANOGP8. We examine the role of NANOGP8 in cell cycle progression. RESULTSIn the prostate cells the NANOG RNA was transcribed from NANOGP8 and not from NANOG1. Cells with the activated 5flanking region of NANOGP8 exhibited enhanced clonogenicity, sphere formation, and xenograft tumor growth. The sphere culture and tumor initiation mouse mode promoted the activation of the 5flanking region of NANOGP8. Forced expression of NANOGP8 increased the entry into the cell cycle. DISCUSSIONIn prostate cells NANOGP8 is a predominant molecule of NANOG. The activation of 5flanking sequence of NANOGP8 could play a role in the regulation of the stem-like properties of cancer stem cells and prostate tumor initiation and development. The microenvironment favoring cancer stem cells could promote the activation of the 5flanking region of NANOGP8. Prostate 74:381-394, 2014. (c) 2013 Wiley Periodicals, Inc.

We comprehensively compared various normalization of gene expression profiles, feature selection and classification algorithms for the classification of these 105 chemicals into14 compound classes. We found that normalization had little effect on the averaged classification accuracy. Two support vector machine (SVM) methods, LibSVM and sequential minimal optimization, had better classification performance than other methods. SVM recursive feature selection (SVM-RFE) had the highest overfitting rate when an independent dataset was used for a prediction. Therefore, we developed a new feature selection algorithm called gradient method that had a relatively high training classification as well as prediction accuracy with the lowest overfitting rate of the methods tested. Analysis of biomarkers that distinguished the 14 classes of compounds identified a group of genes principally involved in cell cycle function that were significantly downregulated by metal and inflammatory compounds, but were induced by anti-microbial, cancer related drugs, pesticides, and PXR mediators. Conclusions: Our results indicate that using microarrays and a supervised machine learning approach to predict chemical toxicants, their potential toxicity and mechanisms of action is practical and efficient. Choosing the right feature and classification algorithms for this multiple category classification and prediction is critical.

Relative stability of the configurations is identified and bandgap tunability is demonstrated through the application of an external, perpendicularly applied electric field. We carefully examine the bandgap's sensitivity to both magnitude of the applied field as well as separation between the graphene and hexagonal boron nitride layers. Features of the band structure are examined and configuration-dependent relationships between the field and bandgap are revealed and elucidated through the atom-projected density of states. These findings suggest the potential for opening and modulating a bandgap in graphene as high as several hundred meV. (C) 2014 AIP Publishing LLC.

An exponential line-shape of the absorption tail in HgCdTe is identified by IPE fittings of the near-threshold quantum yield spectra. The reduction of quantum yield (at higher photon energy) below the fitting value is explained as a result of carrier-phonon scatterings. In addition, the obtained bias independence of the IPE threshold indicates a negligible electron barrier at the heterojunction interface. (C) 2014 AIP Publishing LLC. C1 [Lao, Yan-Feng; Perera, A. G.

Here we examine sea ice conditions during nine summers between 2000 and 2013 in the interior of the ice pack, using autonomous measurements of sea ice mass balance deployed near the North Pole. Results exhibit no definitive trends. There is large interannual variability, with surface melt ranging from 0.02m to 0.50m and bottom melt from 0.10m to 0.57m. The largest amounts of bottom melt have occurred in the past few years. For all 9 years the ice at the end of the melt season was at least 1.2m thick.

Underlying the limits are restrictive sum rules that constrain the distribution of quasistatic eigenvalues. Surprisingly, optimally designed spheroids, with only a single quasistatic degree of freedom, reach the upper bounds for four permittivity values. Away from these permittivities, we demonstrate computationally optimized structures that surpass spheroids and approach the fundamental limits. C1 [Miller, O. D.; Reid, M. T. H.; Johnson, S.

In this work, we designed and fabricated a free-standing, binder-free Na2/3Fe1/2Mn1/2O2@graphene composite via a filtration process. The porous composite led to excellent electrochemical performance due to the facile transport for electrons and ions that was characterized by electrochemical impedance spectroscopy at different temperatures. The electrode delivered a reversible capacity of 156 mAh/g with high Coulombic efficiency. The importance of a fluorinated electrolyte additive with respect to the performance of this high-voltage cathode in Na-ion batteries was also investigated.

The alloys were studied with the aim of comparing the effect of substituting Y and Zr in place of Al, in Cu-Al alloys, on the grain size stability at elevated temperatures. The as-milled alloys were subjected to annealing at various temperatures between 200 and 900 degrees C and the resulting grain morphology has been studied using X-ray diffraction and transmission electron microscopy. The addition of Y results in significantly reduced susceptibility to grain growth whereas in case of CuAl and CuAlZr alloys, the susceptibility to grain growth was much higher. The hardness is substantially increased due to Zr and Y addition in the as-milled CuAl powders. However, the hardness of Cu-12Al-2Zr gradually decreases and approaches that of Cu-14Al alloy after the annealing treatment whereas in case of Cu-12Al-2Y alloy, the relative drop in the hardness is much lower after annealing. Accordingly, the efficacy of grain size stabilization by Y addition at high homologous temperatures has been explained on the basis of a recent thermodynamic stabilization models.

Freshly harvested suspensions of S. flexneri 2a vaccine candidates WRSf2G12 and WRSf2G15 as well as S. sonnei vaccine candidate WRSs3 were nasogastrically administered to groups of rhesus monkeys, Macaca mulatto, either in a monovalent form or when combined with each other. The animals were monitored daily for physical well-being, stools were subjected to quantitative colony immunoblot assays for bacterial excretion and blood and stools were evaluated for humoral and mucosal immune responses. No clinical symptoms were noted in any group of animals and the vaccine candidates were excreted robustly for 48-72 h without significant changes in either the magnitude or duration of excretion when given as a monovalent or as bivalent mixtures. Similarly, immunological interferences were not apparent in the magnitude of humoral and mucosal immune responses observed toward Shigella-specific antigens when monkeys were fed monovalent or bivalent formulations. These results predict that a multivalent live oral vaccine of more than one serotype can have a favorable outcome for protection against shigellosis. Published by Elsevier Ltd. C1 [Ranaallo, R.

Zeolite adsorbents are used in a variety of applications due to their high surface area and abilities to adsorb or desorb sorbates depending upon the applied conditions. With increasing numbers of applications, the ability to predict the performance of zeolites for a wide range of adsorbates would be very valuable in pre-optimizing systems and reducing product development time. The seventh challenge focused, in particular, on the adsorption of perfluorohexane in BCR-704 Faujasite Zeolite. Entrants were challenged to predict the adsorption of perfluorohexane in the zeolite at 293 K and at relative pressures of 0.01, 0.05, 0.1, 0.2, 0.4, 0.6, and 0.8. The relative pressure is defined as that relative to the bulk saturation pressure predicted by the model at a given temperature (293 K in this case). The predictions were judged by comparison to a benchmark set of experimentally determined values. Overall good agreement and consistency were found between the predictions of most entrants.

We compared two regimens of dihydroartemisinin-piperaquine in military and civilians on the Thai-Cambodian border to evaluate national treatment policy. Methods: Efficacy and safety of two and three-day regimens of dihydroartemisinin-piperaquine were compared as a nested open-label evaluation within a malaria cohort study in 222 otherwise healthy volunteers (18% malaria-infected at baseline). The first 80 volunteers with slide-confirmed Plasmodium falciparum or vivax malaria were randomized 1: 1 to receive either regimen (total dose 360mg dihydroartemisinin and 2880mg piperaquine) and followed weekly for up to 6 months. The primary endpoint was malaria recurrence by day 42. Volunteers with vivax infection received primaquine at study discharge with six months follow-up. Results: Eighty patients (60 vivax, 15 falciparum, and 5 mixed) were randomized to dihydroartemisinin-piperaquine. Intention-to-treat all-species efficacy at Day 42 was 85% for the two-day regimen (95% CI 69-94) and 90% for the three-day regimen (95% CI 75-97). PCR-adjusted falciparum efficacy was 75% in both groups with nearly half (45%) still parasitemic at Day 3. Plasma piperaquine levels were comparable to prior published reports, but on the day of recrudescence were below measurable in vitro piperaquine IC50 levels in all falciparum treatment failures. Conclusions: In the brief period since introduction of dihydroartemisinin-piperaquine, there is early evidence suggesting declining efficacy relative to previous reports. Parasite IC50 levels in excess of plasma piperaquine levels seen only in treatment failures raises concern for clinically significant piperaquine resistance in Cambodia. These findings warrant improved monitoring of clinical outcomes and follow-up, given few available alternative drugs.

TI Human Traumatic Brain Injury Induces Autoantibody Response against Glial Fibrillary Acidic Protein and Its Breakdown Products SO PLOS ONE LA English DT Article ID SPINAL-CORD-INJURY; ALPHA-II-SPECTRIN; CENTRAL-NERVOUS-SYSTEM; GLASGOW OUTCOME SCALE; MULTIPLE-SCLEROSIS; ANTIMYELIN ANTIBODIES; ALZHEIMERS-DISEASE; ANTIPITUITARY ANTIBODIES; CEREBROSPINAL-FLUID; HEAD-INJURY AB The role of systemic autoimmunity in human traumatic brain injury (TBI) and other forms of brain injuries is recognized but not well understood. In this study, a systematic investigation was performed to identify serum autoantibody responses to brain-specific proteins after TBI in humans. TBI autoantibodies showed predominant immunoreactivity against a cluster of bands from 38-50 kDa on human brain immunoblots, which were identified as GFAP and GFAP breakdown products. GFAP autoantibody levels increased by 7 days after injury, and were of the IgG subtype predominantly. Results from in vitro tests and rat TBI experiments also indicated that calpain was responsible for removing the amino and carboxyl termini of GFAP to yield a 38 kDa fragment. Additionally, TBI autoantibody staining co-localized with GFAP in injured rat brain and in primary rat astrocytes. These results suggest that GFAP breakdown products persist within degenerating astrocytes in the brain. Anti-GFAP autoantibody also can enter living astroglia cells in culture and its presence appears to compromise glial cell health. TBI patients showed an average 3.77 fold increase in anti-GFAP autoantibody levels from early (0-1 days) to late (7-10 days) times post injury. Changes in autoantibody levels were negatively correlated with outcome as measured by GOS-E score at 6 months, suggesting that TBI patients with greater anti-GFAP immune-responses had worse outcomes. Due to the long lasting nature of IgG, a test to detect anti-GFAP autoantibodies is likely to prolong the temporal window for assessment of brain damage in human patients. C1 [Zoltewicz, J.

Lambrechts, Louis TI Differential Susceptibility of Two Field Aedes aegypti Populations to a Low Infectious Dose of Dengue Virus SO PLOS ONE LA English DT Article ID FRENCH-POLYNESIA; DISEASE SEVERITY; VIREMIA; THAILAND; TRANSMISSION; CHILDREN; VILLAGES; STRAINS; BURDEN AB Background: The infectious dose required to infect mosquito vectors when they take a blood meal from a viremic person is a critical parameter underlying the probability of dengue virus (DENV) transmission. Because experimental vector competence studies typically examine the proportion of mosquitoes that become infected at intermediate or high DENV infectious doses in the blood meal, the minimum blood meal titer required to infect mosquitoes is poorly documented. Understanding the factors influencing the lower infectiousness threshold is epidemiologically significant because it determines the transmission potential of humans with a low DENV viremia, possibly including inapparent infections, and during the onset and resolution of the viremic period of acutely infected individuals. Methodology/Principal Findings: We compared the susceptibility of two field-derived Aedes aegypti populations from Kamphaeng Phet, Thailand when they were orally exposed to low titers of six DENV-2 isolates derived from the serum of naturally infected humans living in the same region. The infectious dose, time-point post-blood feeding, viral isolate and mosquito population, were significant predictors of the proportion of mosquitoes that became infected. Importantly, the dose-response profile differed significantly between the two Ae. aegypti populations. Although both mosquito populations had a similar 50% oral infectious dose (OID50), the slope of the dose-response was shallower in one population, resulting in a markedly higher susceptibility at low blood meal titers. Conclusions/Significance: Our results indicate that mosquitoes in nature vary in their infectious dose-response to DENV. Thus, different mosquito populations have a differential ability to acquire DENV infection at low viremia levels. Future studies on human-to-mosquito DENV transmission should not be limited to OID50 values, but rather they should be expanded to account for the shape of the dose-response profile across a range of virus titers.

This study quantified mediolateral margins of stability (MOS) and MOS sub-components in young individuals with traumatic unilateral transtibial amputation (TTA) and young able-bodied individuals (AB). Thirteen AB and nine TTA completed five 3-min walking trials in a Computer Assisted Rehabilitation ENvironment (CAREN) system under each of three test conditions: no perturbations, pseudo-random mediolateral translations of the platform, and pseudo-random mediolateral translations of the visual field. Compared to the unperturbed trials, TTA exhibited increased mean MOS and MOS variability during platform and visual field perturbations (p < 0.010). AB exhibited increased mean MOS during visual field perturbations and increased MOS variability during both platform and visual field perturbations (p < 0.050). During platform perturbations, TTA exhibited significantly greater values than AB for mean MOS (p < 0.050) and MOS variability (p < 0.050); variability of the lateral distance between the center of mass (COM) and base of support at initial contact (p < 0.005); mean and variability of the range of COM motion (p < 0.010); and variability of COM peak velocity (p < 0.050). As determined by mean MOS and MOS variability, young and otherwise healthy individuals with transtibial amputation achieved lateral stability similar to that of their able-bodied counterparts during unperturbed and visually-perturbed walking. However, based on mean and variability of MOS, unilateral transtibial amputation was shown to have affected lateral walking stability during platform perturbations. Published by Elsevier Ltd.

By contrast, vaccination with VAX003 (consisting of only AIDSVAX B/E) was not protective. Because protection within RV144 was observed in the absence of neutralizing antibody activity or cytotoxic T cell responses, we speculated that the specificity or qualitative differences in Fc-effector profiles of nonneutralizing antibodies may have accounted for the efficacy differences observed between the two trials. We show that the RV144 regimen elicited nonneutralizing antibodies with highly coordinated Fc-mediated effector responses through the selective induction of highly functional immunoglobulin G3 (IgG3). By contrast, VAX003 elicited monofunctional antibody responses influenced by IgG4 selection, which was promoted by repeated AIDSVAX B/E protein boosts. Moreover, only RV144 induced IgG1 and IgG3 antibodies targeting the crown of the HIV envelope V2 loop, albeit with limited coverage of breakthrough viral sequences. These data suggest that subclass selection differences associated with coordinated humoral functional responses targeting strain-specific protective V2 loop epitopes may underlie differences in vaccine efficacy observed between these two vaccine trials.

Antibodies of the same epitope specificity but of a different subclass therefore can have different antibody effector functions. The study of IgG subclass profiles between different vaccine regimens used in clinical trials with divergent efficacy outcomes can provide information on the quality of the vaccine-induced B cell response. We show that HIV-1-specific IgG3 distinguished two HIV-1 vaccine efficacy studies (RV144 and VAX003 clinical trials) and correlated with decreased risk of HIV-1 infection in a blinded follow-up case-control study with the RV144 vaccine. HIV-1-specific IgG3 responses were not long-lived, which was consistent with the waning efficacy of the RV144 vaccine. These data suggest that specific vaccine-induced HIV-1 IgG3 should be tested in future studies of immune correlates in HIV-1 vaccine efficacy trials.

MEAM and EAM potentials were used for MD simulations, and DFT calculations were performed to test the accuracy of different common parameter sets for MEAM and EAM potentials in predicting GSF with different fractions of vacancy defects. Vacancy defects were placed at the stacking fault plane or at nearby atomic layers. The effect of vacancy defects at the stacking fault plane and the plane directly underneath of it was dominant compared to the effect of vacancies at other adjacent planes. The effects of vacancy fraction, the distance between vacancies, and lateral relaxation of atoms on the GSF curves with vacancy defects were investigated. A very similar variation of normalized SFEs with respect to vacancy fractions were observed for Ni and Cu. MEAM potentials qualitatively captured the effect of vacancies on GSF.

TI Anti-sporozoite antibodies as alternative markers for malaria transmission intensity estimation SO MALARIA JOURNAL LA English DT Article DE Malaria; Antibody seroconversion rate; Seroreversion rate; Transmission intensity; Sporozoite antigens; ELISA ID PLASMODIUM-FALCIPARUM TRANSMISSION; SPOROZOITE SURFACE-ANTIGENS; ACQUIRED-IMMUNITY; NORTHERN TANZANIA; EXPOSURE; GHANA; VIVAX; AREA; IDENTIFICATION; PERSISTENCE AB Background: Reported malaria cases continue to decline globally, and this has been attributed to strategic implementation of multiple malaria control tools. Gains made would however need to be sustained through continuous monitoring to ensure malaria elimination and eradication. Entomological inoculation rate (EIR) is currently the standard tool for transmission monitoring but this is not sensitive enough, especially in areas of very low transmission. Transmission estimation models based on seroconversion rates (lambda) of antibodies to Plasmodium falciparum blood stage antigens are gaining relevance. Estimates of lambda, which is the measure of transmission intensity, correlate with EIR but are limited by long-term persistence of antibodies to blood stage antigens. Seroprevalence of antibodies to sporozoite antigens may be better alternatives since these antigens usually have shorter immune exposure times. The aim of this study was to develop transmission estimation models based on the seroprevalence of antibodies to two P. falciparum sporozoite antigens (CSP, CelTOS) and compare with models based on the classical blood stage antigen AMA1. Methods: Antibody levels in archived plasma from three cross-sectional surveys conducted in 2009 in a low transmission area of Southern Ghana were assessed by indirect ELISA. Seroprevalence of antibodies against CSP, CelTOS and AMA1 were fitted to reversible catalytic models to estimate lambda and corresponding seroreversion rates (rho) for each antibody. Results: Of the three models developed, the anti-CSP model predicted a 13-fold decrease in lambda four years prior to the time of sampling (2009). Anti-AMA1 antibodies formed at a four-fold greater rate compared to that of anti-CelTOS antibodies, and anti-CSP antibodies during the period of decreased lambda. In contrast, anti-AMA1 antibodies decayed at a five-fold slower rate relative to that of anti-CSP antibodies while anti-AMA1 and anti-CelTOS antibody decay rates were not significantly different. Anti-CSP antibodies were relatively short-lived as they formed at an 11.6-fold slower rate relative to their decay during the period of decreased lambda. Conclusions: These features of anti-CSP antibodies can be exploited for the development of models for predicting seasonal, short-term changes in transmission intensity in malaria-endemic areas, especially as the elimination phase of malaria control is approached.

TI Trapping of individual airborne absorbing particles using a counterflow nozzle and photophoretic trap for continuous sampling and analysis SO APPLIED PHYSICS LETTERS LA English DT Article ID FORCE OPTICAL TRAP; DIELECTRIC PARTICLES; RADIATION PRESSURE; AIR; MANIPULATION; LEVITATION; AEROSOL AB We describe an integrated opto-aerodynamic system and demonstrate that it enables us to trap absorbing airborne micron-size particles from air, hold them and then release them, and to repeat this sequence many times as would be appropriate for continuous sampling of particles from air. The key parts of the system are a conical photophoretic optical trap and a counter-flow coaxial-double-nozzle that concentrates and then slows particles for trapping. This technology should be useful for on-line applications that require monitoring (by single particle analyses) of a series of successively arriving particles (e.g., from the atmosphere or pharmaceutical or other production facilities) where the total sampling time may last from minutes to days, but where each particle must be held for a short time for measurements (e.g., Raman scattering).

Case studies were first reviewed to investigate feasibility of the concept. Next, an overall emergency paving framework was developed, complemented by a two-component laboratory investigation. Component one developed a series of short-term ageing protocols for use in preparation of test specimens; component two evaluated those specimens for compactability and rut resistance. Results indicated that (1) material could be hauled up to 6h and still be effectively used in emergency paving, (2) the two warm mix additives studied improved compactability of hot-mixed and warm-compacted asphalt and (3) rut resistance was acceptable for emergency applications. A discussion on the post natural disaster permanent residual value of the hot-mixed and warm-compacted material is also provided.

In gene set enrichment analysis (GSEA), a score that can combine fold change and P-value together is needed for better gene ranking. Results: We defined a gene significance score pi-value by combining expression fold change and statistical significance (P-value), and explored its statistical properties. When compared to various existing methods, pi-value based approach is more robust in selecting DE genes, with the largest area under curve in its receiver operating characteristic curve. We applied pi-value to GSEA and found it comparable to P-value and t-statistic based methods, with added protection against false discovery in certain situations. Finally, in a gene functional study of breast cancer profiles, we showed that using pi-value helps elucidating otherwise overlooked important biological functions.

TI Facial recognition of heroin vaccine opiates: Type 1 cross-reactivities of antibodies induced by hydrolytically stable haptenic surrogates of heroin, 6-acetylmorphine, and morphine SO VACCINE LA English DT Article DE Haptens; Heroin; 6-Acetylmorphine; Morphine; Type 1 and type 2 cross-reactivity; Liposomes; Monophosphoryl lipid A; Tetanus toxoid; Vaccines to drugs of abuse ID CONJUGATE VACCINE; ADJUVANT SYSTEM; RELAPSE; BEHAVIORS; LIPOSOMES; ABUSE; RATS AB Novel synthetic compounds similar to heroin and its major active metabolites, 6-acetylmorphine and morphine, were examined as potential surrogate haptens for the ability to interface with the immune system for a heroin vaccine. Recent studies have suggested that heroin-like haptens must degrade hydrolytically to induce independent immune responses both to heroin and to the metabolites, resulting in antisera containing mixtures of antibodies (type 2 cross-reactivity). To test this concept, two unique hydrolytically stable haptens were created based on presumed structural facial similarities to heroin or to its active metabolites. After conjugation of a heroin-like hapten (DiAmHap) to tetanus toxoid and mixing with liposomes containing monophosphotyl lipid A, high titers of antibodies after two injections in mice had complementary binding sites that exhibited strong type 1 ("true") specific cross-reactivity with heroin and with both of its physiologically active metabolites. Mice immunized with each surrogate hapten exhibited reduced antinociceptive effects caused by injection of heroin. This approach obviates the need to create hydrolytically unstable synthetic heroin-like compounds to induce independent immune responses to heroin and its active metabolites for vaccine development. Facial recognition of hydrolytically stable surrogate haptens by antibodies together with type 1 cross-reactivities with heroin and its metabolites can help to guide synthetic chemical strategies for efficient development of a heroin vaccine.

TI Evaluation of Dengue Virus strains for human challenge studies SO VACCINE LA English DT Article DE Dengue; Virus; Vaccine; Challenge ID DOG KIDNEY-CELLS; HEMORRHAGIC-FEVER; NEUTRALIZING ANTIBODIES; VOLUNTEER CHALLENGE; PROTECTIVE EFFICACY; FALCIPARUM-MALARIA; ATTENUATED DENGUE; SERIAL PASSAGE; VACCINE; CANDIDATE AB Discordance between the measured levels of dengue virus neutralizing antibody and clinical outcomes in the first-ever efficacy study of a dengue tetravalent vaccine (Lancet, Nov 2012) suggests a need to re-evaluate the process of pre-screening dengue vaccine candidates to better predict clinical benefit prior to large-scale vaccine trials. In the absence of a reliable animal model and established correlates of protection for dengue, a human dengue virus challenge model may provide an approach to down-select vaccine candidates based on their ability to reduce risk of illness following dengue virus challenge. We report here the challenge of flavivirus-naive adults with cell culture-passaged dengue viruses (DENV) in a controlled setting that resulted in uncomplicated dengue fever (DF). This sets the stage for proof-of-concept efficacy studies that allow the evaluation of dengue vaccine candidates in healthy adult volunteers using qualified DENV challenge strains well before they reach field efficacy trials involving children. Fifteen flavivirus-naive adult volunteers received 1 of 7 DENV challenge strains (n = 12) or placebo (n = 3). Of the twelve volunteers who received challenge strains, five (two DENV-1 45AZ5 and three DENV-3 CH53489 cl24/28 recipients) developed DF, prospectively defined as >= 2 typical symptoms, >= 48 h of sustained fever (> 100.4 degrees F) and concurrent viremia. Based on our study and historical data, we conclude that the DENV-1 and DENV-3 strains can be advanced as human challenge strains. Both of the DENV-2 strains and one DENV-4 strain failed to meet the protocol case definition of DF. The other two DENV-4 strains require additional testing as the illness approximated but did not satisfy the case definition of DF. Three volunteers exhibited effusions (1 pleural/ascites, 2 pericardial) and 1 volunteer exhibited features of dengue (rash, lymphadenopathy, neutropenia and thrombocytopenia), though in the absence of fever and symptoms. The occurrence of effusions in milder DENV infections counters the long-held belief that plasma leakage syndromes are restricted to dengue hemorrhagic fever/dengue shock syndromes (DHF/DSS). Hence, the human dengue challenge model may be useful not only for predicting the efficacy of vaccine and therapeutic candidates in small adult cohorts, but also for contributing to our further understanding of the mechanisms behind protection and virulence.

TI Multi-scale coarse-graining of non-conservative interactions in molecular liquids SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID DISSIPATIVE PARTICLE DYNAMICS; MESOSCOPIC SIMULATION; INTERACTION POTENTIALS; BIOMOLECULAR SYSTEMS; COMPUTER-SIMULATION; OPTIMAL PREDICTION; BROWNIAN-MOTION; POLYMER MELT; NITROMETHANE; SURFACTANTS AB A new bottom-up procedure for constructing non-conservative (dissipative and stochastic) interactions for dissipative particle dynamics (DPD) models is described and applied to perform hierarchical coarse-graining of a polar molecular liquid (nitromethane). The distant-dependent radial and shear frictions in functional-free form are derived consistently with a chosen form for conservative interactions by matching two-body force-velocity and three-body velocity-velocity correlations along the microscopic trajectories of the centroids of Voronoi cells (clusters), which represent the dissipative particles within the DPD description. The Voronoi tessellation is achieved by application of the K-means clustering algorithm at regular time intervals. Consistently with a notion of many-body DPD, the conservative interactions are determined through the multi-scale coarse-graining (MS-CG) method, which naturally implements a pairwise decomposition of the microscopic free energy. A hierarchy of MS-CG/DPD models starting with one molecule per Voronoi cell and up to 64 molecules per cell is derived. The radial contribution to the friction appears to be dominant for all models. As the Voronoi cell sizes increase, the dissipative forces rapidly become confined to the first coordination shell. For Voronoi cells of two and more molecules the time dependence of the velocity autocorrelation function becomes monotonic and well reproduced by the respective MS-CG/DPD models. A comparative analysis of force and velocity correlations in the atomistic and CG ensembles indicates Markovian behavior with as low as two molecules per dissipative particle. The models with one and two molecules per Voronoi cell yield transport properties (diffusion and shear viscosity) that are in good agreement with the atomistic data. The coarser models produce slower dynamics that can be appreciably attributed to unaccounted dissipation introduced by regular Voronoi re-partitioning as well as by larger numerical errors in mapping out the dissipative forces. The framework presented herein can be used to develop computational models of real liquids which are capable of bridging the atomistic and mesoscopic scales.

TI A methodology to identify and quantify mobility-reducing defects in 4H-silicon carbide power metal-oxide-semiconductor field-effect transistors SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID 4H-SIC MOSFETS; SIC/SIO2 INTERFACE; PASSIVATION AB In this paper, we present a methodology for the identification and quantification of defects responsible for low channel mobility in 4H-Silicon Carbide (SiC) power metal-oxide-semiconductor field-effect transistors (MOSFETs). To achieve this, we use an algorithm based on 2D-device simulations of a power MOSFET, density functional simulations, and measurement data. Using physical modeling of carrier mobility and interface traps, we reproduce the experimental I-V characteristics of a 4H-SiC doubly implanted MOSFET through drift-diffusion simulation. We extract the position of Fermi level and the occupied trap density as a function of applied bias and temperature. Using these inputs, our algorithm estimates the number of possible trap types, their energy levels, and concentrations at 4H-SiC/SiO2 interface. Subsequently, we use density functional theory (DFT)-based ab initio simulations to identify the atomic make-up of defects causing these trap levels. We study silicon vacancy and carbon di-interstitial defects in the SiC side of the interface. Our algorithm indicates that the D-it spectrum near the conduction band edge (3.25 eV) is composed of three trap types located at 2.8-2.85 eV, 3.05 eV, and 3.1-3.2 eV, and also calculates their densities. Based on DFT simulations, this work attributes the trap levels very close to the conduction band edge to the C di-interstitial defect. (C) 2014 AIP Publishing LLC. C1 [Ettisserry, D.

Above threshold, the emission was transverse-electric polarized and as narrow as 1.8 nm without a cavity. The DH and MQW structures showed gain values of 50-60 cm(-1) when pumped at 1 MW/cm(2). The results demonstrated the excellent optical quality of the AlGaN-based heterostructures grown on AlN substrates and their potential for realizing electrically pumped sub-280 nm laser diodes.

Fish oil as dietary supplements, however, show moderate clinical efficacy, highlighting an immediate scope of systematic in vitro feedback. Our transcriptomic study was designed to investigate the genomic shift of murine brains fed on fish oil enriched diets. A customized fish oil enriched diet (FD) and standard lab diet (SD) were separately administered to two randomly chosen populations of C57BL/6J mice from their weaning age until late adolescence. Statistical analysis mined 1,142 genes of interest (GOI) differentially altered in the hemibrains collected from the FD- and SD-fed mice at the age of five months. The majority of identified GOI (similar to 40%) encodes proteins located in the plasma membrane, suggesting that fish oil primarily facilitated the membrane-oriented biofunctions. FD potentially augmented the nervous system's development and functions by selectively stimulating the Src-mediated calcium-induced growth cascade and the downstream PI3K-AKT-PKC pathways. FD reduced the amyloidal burden, attenuated oxidative stress, and assisted in somatostatin activation-the signatures of attenuation of Alzheimer's disease, Parkinson's disease, and affective disorder. FD induced elevation of FKBP5 and suppression of BDNF, which are often linked with the improvement of anxiety disorder, depression, and post-traumatic stress disorder. Hence we anticipate efficacy of FD in treating illnesses such as depression that are typically triggered by the hypoactivities of dopaminergic, adrenergic, cholinergic, and GABAergic networks. Contrastingly, FD's efficacy could be compromised in treating illnesses such as bipolar disorder and schizophrenia, which are triggered by hyperactivities of the same set of neuromodulators. A more comprehensive investigation is recommended to elucidate the implications of fish oil on disease pathomechanisms, and the result-driven repositioning of fish oil utilization may revitalize its therapeutic efficacy.

TI Genomic Characterization of Group C Orthobunyavirus Reference Strains and Recent South American Clinical Isolates SO PLOS ONE LA English DT Article ID ARTHROPOD-BORNE VIRUSES; FAMILY BUNYAVIRIDAE; PHYLOGENETIC-RELATIONSHIPS; MOLECULAR EPIDEMIOLOGY; SCHMALLENBERG VIRUS; SEQUENCE ALIGNMENTS; RNA VIRUSES; S SEGMENT; IDENTIFICATION; PROTEIN AB Group C orthobunyaviruses (family Bunyaviridae, genus Orthobunyavirus), discovered in the 1950s, are vector-borne human pathogens in the Americas. Currently there is a gap in genomic information for group C viruses. In this study, we obtained complete coding region sequences of reference strains of Caraparu (CARV), Oriboca (ORIV), Marituba (MTBV) and Madrid (MADV) viruses, and five clinical isolates from Peru and Bolivia, using an unbiased de novo approach consisting of random reverse transcription, random anchored PCR amplification, and high throughput pyrosequencing. The small, medium, and large segments encode for a 235 amino acid nucleocapsid protein, an approximately 1430 amino acid surface glycoprotein polyprotein precursor, and a 2248 amino acid RNA-dependent RNA polymerase, respectively. Additionally, the S segment encodes for an 83 amino acid non-structural protein, although this protein is truncated or silenced in some isolates. Phylogenetically, three clinical isolates clustered with CARV, one clustered with MTBV, and one isolate appeared to be a reassortant or a genetic drift resulted from the high variability of the medium segment which was also seen in a few other orthobunyaviruses. These data represent the first complete coding region sequences for this serocomplex of pathogenic orthobunyaviruses. The genome-wide phylogeny of reference strains is consistent with the antigenic properties of the viruses reported in the original serological studies conducted in the 1960s. Comparative analysis of conserved protein regions across group C virus strains and the other orthobunyavirus groups revealed that these group C viruses contain characteristic domains of potential structural and functional significance. Our results provide the basis for the developments of diagnostics, further genetic analyses, and future epidemiologic studies of group C viruses.

The PSI monomer is isolated by disassembling a purified PSI trimer using a freeze thaw technique in presence of the short-chain surfactant, octylthioglucoside. Photoactive electrodes are constructed with PSI, functioning as both light absorber and charge-separator, embedded within a conductive polymer film. Despite structural differences between PSI trimers and monomers, electrodes cast with equal chlorophyll-a concentration generate similar photoactivities. Photoaction spectra show that all photocurrent derived from electrodes of PSI and conductive polymer originates solely from PSI with no photocurrent caused by redox mediators in the conductive polymer film. Longevity studies show that the two forms of PSI photodegrade at the same rate while exposed to equal intensities of 676 nm light. Direct photo-oxidation measurements indicate that PSI's monomeric form has fewer light harvesting antennae than trimer, and also shows energy sharing between monomeric subunits in the trimer. The structure of PSI is also found to impact cell performance when applying light at incident powers above 1.5 mW/cm(2) due to the reduced optical cross-section in the monomer, causing saturation at lower light intensities than the trimer.

In the adult, TrkA and its ligand NGF are peripheral pain mediators, particularly in inflammatory pain states. However, how TrkA regulates the function of nociceptive neurons and whether its activity levels may lead to sensory abnormalities is still unclear. Here we report the characterization of a 3 aa (KFG) domain that negatively regulates TrkA level and function in response to NGF. Deletion of this domain in mouse causes a reduction of TrkA ubiquitination leading to an increase in TrkA protein levels and activity. The number of dorsal root ganglia neurons is not affected by the mutation. However, mutant mice have enhanced thermal sensitivity and inflammatory pain. Together, these data suggest that ubiquitination is a mechanism used in nociceptive neurons to regulate TrkA level and function. Our results may enhance our understanding of how ubiquitination affects TrkA activation following noxious thermal stimulation and inflammatory pain.

The most effective experimental vaccines confer only limited and short-lived protection despite production of protective antibodies. However, immunization with irradiated sporozoites, or with live sporozoites under chloroquine cover, has resulted in long-term protection apparently due to the generation of protective CD8+ T cells. The nature and function of these protective CD8+ T cells has not been elucidated. In the current study, the phenotype of CD8+ T cells generated after immunization of C57BL/6 mice with live Plasmodium berghei sporozoites under chloroquine cover was investigated. Methods: Female C57BL/6 mice, C57BL/6 mice B2 macroglobulin -/- [KO], or invariant chain-/- [Ic KO] [6-8 weeks old] were immunized with P. berghei sporozoites and treated daily with 800 mu g/mouse of chloroquine for nine days. This procedure of immunization is referred to as "infection/cure". Mice were challenged by inoculating intravenously 1,000 infectious sporozoites. Appearance of parasitaemia was monitored by Giemsa-stained blood smears. Results: By use of MHC I and MHC II deficient animals, results indicate that CD8+ T cells are necessary for full protection and that production of protective antibodies is either CD4+ T helper cells dependent and/or lymphokines produced by CD4 cells contribute to the protection directly or by helping CD8+ T cells. Further, the phenotype of infection/cure P. berghei responsive CD8+ T cells was determined to be KLRG1(high) CD27(low) CD44(high) and CD62L(low). Conclusion: The KLRG1(high) CD27(low) CD44(high) and CD62L(low) phenotype of CD8+ T cells is associated with protection and should be investigated further as a candidate correlate of protection.

We have performed nanoindentation strain rate jump experiments to measure the hardness values at different loading rates, and determine the strain rate sensitivity (SRS). In turn, the activation volume (V*) associated with plastic deformation of the ECAE Cu has,been derived and analyzed. Based on the dislocation-mediated processes during ECAE, including dislocation accumulation, dynamic recovery and recrystallization, combined with creep theory, a strain rate dependent constitutive model has been constructed for the ECAE Cu. We have reached good agreement between the model predictions and the experimental results. It was found that the model can provide a plausible understanding of the various aspects of the mechanical behavior of the ECAE Cu. (C) 2014 Elsevier B.V. All rights reserved.

TI Patient-Reported Quality of Supportive Care Among Patients With Colorectal Cancer in the Veterans Affairs Health Care System SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID CELL LUNG-CANCER; OF-LIFE; DISTRESS MANAGEMENT; PROSTATE-CANCER; NCCN GUIDELINES; RECALL BIAS; DISPARITIES; ONCOLOGY; COMMUNICATION; COORDINATION AB Purpose High-quality supportive care is an essential component of comprehensive cancer care. We implemented a patient-centered quality of cancer care survey to examine and identify predictors of quality of supportive care for bowel problems, pain, fatigue, depression, and other symptoms among 1,109 patients with colorectal cancer. Patients and Methods Patients with new diagnosis of colorectal cancer at any Veterans Health Administration medical center nationwide in 2008 were ascertained through the Veterans Affairs Central Cancer Registry and sent questionnaires assessing a variety of aspects of patient-centered cancer care. We received questionnaires from 63% of eligible patients (N = 1,109). Descriptive analyses characterizing patient experiences with supportive care and binary logistic regression models were used to examine predictors of receipt of help wanted for each of the five symptom categories. Results There were significant gaps in patient-centered quality of supportive care, beginning with symptom assessment. In multivariable modeling, the impact of clinical factors and patient race on odds of receiving wanted help varied by symptom. Coordination of care quality predicted receipt of wanted help for all symptoms, independent of patient demographic or clinical characteristics. Conclusion This study revealed substantial gaps in patient-centered quality of care, difficult to characterize through quality measurement relying on medical record review alone. It established the feasibility of collecting patient-reported quality measures. Improving quality measurement of supportive care and implementing patient-reported outcomes in quality-measurement systems are high priorities for improving the processes and outcomes of care for patients with cancer.

Previously developed Fe and C single-element potentials were used to develop a Fe-C alloy MEAM potential, using a statistics-based optimization scheme to reproduce structural and elastic properties of cementite, the interstitial energies of C in bcc Fe, and heat of formation of Fe-C alloys in L-12 and B-1 structures. The stability of cementite was investigated by molecular dynamics simulations at high temperatures. The nine single-crystal elastic constants for cementite were obtained by computing total energies for strained cells. Polycrystalline elastic moduli for cementite were calculated from the single-crystal elastic constants of cementite. The formation energies of (001), (010), and (100) surfaces of cementite were also calculated. The melting temperature and the variation of specific heat and volume with respect to temperature were investigated by performing a two-phase (solid/liquid) molecular dynamics simulation of cementite. The predictions of the potential are in good agreement with first-principles calculations and experiments. C1 [Liyanage, Laalitha S.

Here, we report the controllable growth of h-BN on a copper substrate using the atmospheric pressure chemical vapor deposition (APCVD) method using ammonia borane as the precursor. The advantages of using APCVD include its ease of setup utilizing fewer resources, low cost and fast growth, all of which are essential for full film coverage and the mass production of 2D h-BN. In this study, we observed a substrate-position dependent evolution of h-BN domains at various stages of growth as the density and size of the domains increased downstream along the quartz tube. Other critical parameters such as growth temperature, deposition time, temperature and mass of precursor were also systemically investigated in order to understand the factors influencing the growth of the h-BN film. Importantly, with a slight increase in the growth temperature of 50 degrees C, we observe a significant (similar to 17-fold) increase in the average domain size, and its further expansion for a longer duration of growth. Likewise, our parametric study highlights the impact of other crucial parameters on domain size, coverage, and thickness of the h-BN film.

Among the possible structures of the adsorption complexes, the most stable systems possess nitrogen-containing heterocycles in a parallel orientation toward the modeled carbon surface. The adsorption enthalpies, calculated using the rigid rotor-harmonic oscillator approach (RRHO), were in good agreement with available experimental data. This approach was shown to provide sufficiently accurate adsorption enthalpies from the gas phase for the HNC-carbon systems. The vibrational, rotational, and translation contributions to the adsorption entropy were also analyzed by the approach extended beyond the RRHO scheme. The effects of anharmonic vibrations and internal rotations of the adsorbate on the adsorption sites of the modeled carbon surface were estimated. The Gibbs free energies calculated using the RRHO approach were adjusted to take into account the heterogeneity of the carbon surfaces and underestimation of the adsorption enthalpies at the BLYP-D2(PBC) level. The corrected Gibbs free energy values of adsorption are negative for all of the investigated HNC-carbon systems, and they agree well with available experimental data. This suggests an effective adsorption of selected high nitrogen compounds on carbonaceous materials from the gas phase at 298.15 K. Partition coefficients for distribution of high nitrogen compounds on modeled carbon surfaces were also predicted in good agreement with the experimental results.

TI Assessment of Floodplain Vulnerability during Extreme Mississippi River Flood 2011 SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID SENSITIVITY; VALLEY; SEDIMENTATION AB Regional change in the variability and magnitude of flooding could be a major consequence of future global climate change. Extreme floods have the capacity to rapidly transform landscapes and expose landscape vulnerabilities through highly variable spatial patterns of inundation, erosion, and deposition. We use the historic activation of the Birds Point-New Madrid Floodway during the Mississippi and Ohio River Flooding of 2011 as a scientifically unique stress experiment to analyze indicators of floodplain vulnerability. We use pre- and postflood airborne Light Detection and Ranging data sets to locate erosional and depositional hotspots over the 540 km(2) agricultural Floodway. While riparian vegetation between the river and the main levee breach likely prevented widespread deposition, localized scour and deposition occurred near the levee breaches. Eroded gullies nearly 1 km in length were observed at a low ridge of a relict meander scar of the Mississippi River. Our flow modeling and spatial mapping analysis attributes this vulnerability to a combination of erodible soils, flow acceleration associated with legacy fluvial landforms, and a lack of woody vegetation to anchor soil and enhance flow resistance. Results from this study could guide future mitigation and adaptation measures in cases of extreme flooding.

Physicochemical and spectroscopic properties of graphite nanocarbon-impregnated alginate beads (ABGNC) were characterized and compared with those of AB. Co(II) adsorption on ABGNC was quantitatively evaluated by determining kinetics and thermodynamics parameters. The Co(II) adsorption capacity onto ABGNC was highest at neutral pH condition. Increasing the temperature from 288 to 318K resulted in a 2.5-fold higher Co(II) adsorption onto AB, while thermal dependence of Co(II) adsorption on ABGNC was not found. Kinetic studies showed an applicability of the pseudo-second-order kinetic model for both AB and ABGNC. Monolayer adsorption was the dominant mechanism of Co(II) adsorption on both AB and ABGNC. Thermodynamic studies revealed that Co(II) adsorption was an endothermic and spontaneous process. Positive values of entropy indicate randomness in solid/aqueous phases, and mean free energy (E-a) fits in the range of chemisorption.

Vala, Jiri TI Phase-controlled two-qubit quantum gates SO PHYSICAL REVIEW A LA English DT Article ID TRAPPED IONS; ENTANGLEMENT; COMPUTATION AB We consider an implementation of a two-qubit entangling gate between trapped ions controlled by fully overlapping laser pulses. We particularly address the role of a relative phase between the pulses in the gate design. Though, in general, the relative phase determines the exact form of the two-qubit operation, it is shown that it affects only its single qubit part and has no effect on its entangling content. Based on a general canonical decomposition of the evolution operator we demonstrate that the controlled-NOT ( CNOT) gate can be decomposed in terms of a two-qubit entangled gate and single qubit phase gates. Our study shows that any relative phase errors in two-qubit operations related to phase fluctuations of the external fields can be successfully corrected locally by single-qubit operations, which are usually easy to implement.

The increasing number of analogs being identified in edible marine organisms complicates the estimation of the real hazard associated with the presence of PLTXlike compounds. So far, 42-OH-PLTX is one of the few congeners available, and the study of its toxicity represents an important step toward a better comprehension of the mechanism of action of this family of compounds. From this perspective, the aim of this work was to investigate the in vivo and in vitro effect of 42-OH-PLTX on skeletal muscle, one of the most sensitive targets for PLTXs. Our results demonstrate that 42-OH-PLTX causes damage at the skeletal muscle level with a cytotoxic potency similar to that of PLTX. 42-OH-PLTX induces cytotoxicity and cell swelling in a Na+-dependent manner similar to the parent compound. However, the limited Ca2+-dependence of the toxic insult induced by 42-OH-PLTX suggests a specific mechanism of action for this analog. Our results also suggest an impaired response to the physiological agonist acetylcholine and altered cell elasticity. (C) 2013 Elsevier Ireland Ltd. All rights reserved.

The MPAs are surveyed by remotely operated vehicle (ROV) as part of a larger, ongoing effort to evaluate their effectiveness. To determine macroinvertebrate species distribution and richness, we analyzed the ROV video data collected at five paired sites during 2007-2009. Percent occurrence was used to estimate species richness. Macroinvertebrates observed included harvested species and species with structure-forming potential. Fifty-three invertebrate species were identified along with 20 higher taxonomic complex level classifications when identification to species level was not possible. Two of the five site-pairs formed clusters in two different cluster analyses. Site clustering suggested an island effect or clinal change in the biogeographic regions from the Oregonian Province through the Transition Zone to the Californian Province. The ROV surveys yielded new depth records for three invertebrate species. In addition, the cnidarian Stylaster californicus was found offshore of Santa Rosa Island, expanding its documented distribution within the northern Channel Islands. C1 [Miller, Rebecca E.

ERDC-CERL performed building envelope leakage tests on Army facilities to test their general integrity and the effect of increased airtightness on building energy consumption. Results were used to develop airtightness criteria and performance requirements for new construction and major renovation projects, which have been included in Army design/construction strategies. Since 2009, the U. S. Army Corps of Engineers (USACE) has implemented an airtightness requirement in all new construction and building enclosure renovation projects. Engineering and Construction Bulletin (ECB) 2012-16 set levels of airtightness for building enclosures at the material, assembly, and system level. ECB 2012-16 requires whole building air leakage tests to be conducted at completion of construction to verify the constructed air barrier system's performance. The current Air Leakage Test Protocol for Building Envelopes developed by ERDC-CERL, the Air Barrier Association of America (ABAA), and other industrial partners was published in May 2012. This paper presents the results of airtightness tests before and after the new requirements were established, updated results for air leakage tests of more than 285 newly constructed and renovated large buildings, and a performance analysis of the design and construction process, air barrier materials, building use, and construction types. These data may support future decisions regarding airtightness levels to be adopted for commercial buildings.

In controlled laboratory settings this classification approach works well; however, transitioning these approaches into more dynamic, unconstrained environments will present several significant challenges. One such challenge is an increase in temporal variability in measured behavioral and neural responses, which often results in suboptimal classification performance. Previously, we reported a novel classification method designed to account for temporal variability in the neural response in order to improve classification performance by using sliding windows in hierarchical discriminant component analysis (HDCA), and demonstrated a decrease in classification error by over 50% when compared to the standard HDCA method (Marathe et al., 2013). Here, we expand upon this approach and show that embedded within this new method is a novel signal transformation that, when applied to EEG signals, significantly improves the signal-to-noise ratio and thereby enables more accurate single-trial analysis. The results presented here have significant implications for both brain-computer interaction technologies and basic science research into neural processes.

Army OTs have been involved in Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) providing BR treatment to service members, serving in Brigade Combat Teams, and Combat Stress Control Units, however, the impact of the OT BR mission has been scarcely documented. Although the theoretical deployment role of OTs in Combat and Operational Stress Control (COSC) operations has been described, the literature provides minimal experiential application of OTs in the COSC role. This article describes the deployed operational roles of three OTs, two deployed during OIF and one in OEF during 2008-2010. Deployed assignments included positions as Officers in Charge of restoration centers, and of prevention centers to include animal-assisted therapy, and disaster response. Occupational therapists play a vital role within the COSC unit as they add the unique perspective of assessing the service member's functional performance in daily living occupations.

Data collection were conducted in a 5-year span in which 1,323 Special Operations Forces Soldiers were surveyed anonymously from 3 to 6 months after returning from deployment to Iraq/Afghanistan regarding their combat experiences and mental health. Combat items were independently analyzed and placed into the following categories: (1) Fighting, (2) Killing, (3) Threat to oneself, (4) Death/Injury of others, and (5) Atrocities. Alcohol misuse was measured using the Alcohol Use Disorders Identification Test-Consumption. Of the Soldiers sampled, 15% (N = 201) screened positive for alcohol misuse 3 to 6 months postdeployment. Combat experiences relating to fighting, threat to oneself, and atrocities were significantly related to alcohol misuse when analyzed individually. However, when factors were analyzed simultaneously, combat experiences in the fighting category were significantly associated with a positive screen for alcohol misuse. In conclusion, Soldiers belonging to certain elite combat units are significantly more likely to screen positive for alcohol misuse if they are exposed to specific types of fighting combat experiences versus any other type of combat exposure.

TI Impact of Race in Using PSA Velocity to Predict for Prostate Cancer SO MILITARY MEDICINE LA English DT Article ID ANTIGEN VELOCITY; RADICAL PROSTATECTOMY; DOUBLING TIME; GLEASON SCORE; MORTALITY; BIOPSY; RISK AB Objective: To assess whether race is a significant factor in the ability of prostate-specific antigen velocity (PSAV) for predicting high-grade prostate cancer (HGPC). Methods: Records of men who underwent prostate biopsy between January 2003 and December 2007 were retrospectively reviewed to collect demographic data, self-reported race, prostate-specific antigen (PSA) data, and pathology results. PSAV was calculated using linear regression. Subjects were stratified by the presence or absence of HGPC. Median PSA and PSAV values were compared within each racial group using receiver operating characteristic analysis and Student t test. Results: Static PSA was significantly higher in Caucasian men with HGPC (4.81 vs. 8.3 ng/mL, p = 0.0000001) while PSAV was also higher in men with HGPC (0.639 vs. 1.15 ng/mL/yr, p = 0.081). Static PSA in Asians did not perform well in predicting HGPC (5.3 vs. 9.42 ng/mL, p = 0.11), but fared much better than PSAV (0.51 vs. 0.93 ng/mL/yr, p = 0.27). PSA in African Americans did not significantly predict HGPC (6.27 vs. 7.7 ng/mL, p = 0.474), but PSAV showed a stronger trend toward significance (0.615 vs. 1.54 ng/mL/yr, p = 0.068). Conclusions: PSAV may complement static PSA in African Americans and help identify early stage aggressive cancers. C1 [Kallingal, George J.

The study consisted of Millennium Cohort Study participants and used self-reported symptoms. Repeated measures modeling assessed PTSD and depression continuously and dichotomously over time. A subanalysis among only recently deployed personnel was conducted. Of the 52,653 participants for the PTSD analysis, the adjusted PCL-C means were 34.6 for Reservists, 34.4 for National Guardsmen, and 34.7 for active duty members, respectively. Of the 53,073 participants for depression analysis, the adjusted PHQ-9 means were 6.8, 6.7, and 7.2, respectively. In dichotomous models, Reservists and National Guardsmen did not have a higher risk of PTSD or depression compared with active duty members. Among deployers, Reservists and National Guardsmen had higher odds (odds ratio = 1.16, 95% confidence limit [CL] [1.01, 1.34] and OR = 1.19, 95% CL [1.04, 1.36], respectively) of screening positive for PTSD, but not depression. Although Reserve and National Guard deployers had modestly increased odds of PTSD compared with active duty members, overall there were minimal differences in the risk and symptom scores of PTSD and depression between service components.

However, general-purpose computers are not designed with the millisecond-level accuracy of operation required for such applications. Software that does not control for the various sources of delay may return reaction time values that are substantially different from the true reaction times. We have developed and characterized a freely available system for PC-based simple visual reaction time testing that is analogous to the widely used psychomotor vigilance task (PVT). In addition, we have integrated individualized prediction algorithms for near-real-time neurobehavioral performance prediction. We characterized the precision and accuracy with which the system as a whole measures reaction times on a wide range of computer hardware configurations, comparing its performance with that of the "gold standard" PVT-192 device. We showed that the system is capable of measuring reaction times with an average delay of less than 10 ms, a margin of error that is comparable to that of the gold standard. The most critical aspect of hardware selection is the type of mouse used for response detection, with gaming mice showing a significant advantage over standard ones.

Recent reports have described that the growth cone extension is superior across gradients of the ECM protein laminin compared to growth across uniformly distributed laminin. In this work, the authors have prepared gradients of laminin on aligned electrospun nanofibers for use as substrates for neuronal growth. The substrates therefore presented both topographical and chemical guidance cues. Step gradients were prepared by the controlled robotic immersion of plasma-treated polycaprolactone fibers reacted with N-hydroxysuccinimide into the protein solution. The gradients were analyzed using x-ray photoelectron spectroscopy and confocal laser scanning microscopy. Gradients with a dynamic range of protein concentrations were successfully generated and neurite outgrowth was evaluated using neuronlike pheochromocytoma cell line 12 (PC12) cells. After 10 days of culture, PC12 neurite lengths varied from 32.7+/-14.2 mu m to 76.3+/-9.1 mu m across the protein concentration gradient. Neurite lengths at the highest concentration end of the gradient were significantly longer than neurite lengths observed for cells cultured on samples with uniform protein coverage. Gradients were prepared both in the fiber direction and transverse to the fiber direction. Neurites preferentially aligned with the fiber direction in both cases indicating that fiber alignment has a more dominant role in controlling neurite orientation, compared to the chemical gradient.

Fifty-six participants-16 PD participants who underwent LSVT, 12 PD participants who underwent articulation treatment (ARTIC), 17 untreated PD participants, and 11 controls without PD-produced monologues about happy emotional experiences at pre- and post-treatment timepoints ("T1" and "T2," respectively), 1 month apart. The groups of LSVT, ARTIC, and untreated PD participants were matched on demographic and health status variables. The frequency and variability of facial expressions (Frequency and Variability) observable on 1-min monologue videorecordings were measured using the Facial Action Coding System (FACS). At T1, the Frequency and Variability of participants with PD were significantly lower than those of controls. Frequency and Variability increases of LSVT participants from T1 to T2 were significantly greater than those of ARTIC or untreated participants. Whereas the Frequency and Variability of ARTIC participants at T2 were significantly lower than those of controls, LSVT participants did not significantly differ from controls on these variables at T2. The implications of these findings, which suggest that LSVT reduces parkinsonian hypomimia, for PD-related psychosocial problems are considered.

An overview is presented of the biphasic solid-fluid mixture theory at finite strain, including inertia terms. The solid skeleton is modeled as an isotropic, compressible, hyperelastic material. FEA simulations include: (1) compressive uniaxial strain loading on a column of lung parenchyma with either pore air or water fluid, (2) out-of-plane pressure loading on a thin slab of lung parenchyma with either pore air or water fluid, and (3) pressure loading on a 1/8th symmetry vertebral disc (nucleus and annulus) with pore water. For the simulations, mixed formulation Q27P8 and stabilized Q8P8 finite elements are compared ("Q" indicates the number of solid skeleton displacement nodes, and "P" the number of pore fluid pressure nodes). The PEA results demonstrate the interplay of dynamics (wave propagation through solid skeleton and pore fluid), large deformations, effective stress and pore fluid pressure coupling, compressibility and viscosity of pore fluid, and three-dimensional effects for soft biological tissues treated as biphasic porous media.

Typical investigations of multitasking impairments have focused on the performance of two tasks presented in close temporal proximity on discrete trials; however, such paradigms do not match well with the continuous performance situations more typically encountered outside the laboratory. As a result, the stages of information processing that are affected during multisensory continuous dual tasks and how these changes in processing relate to behavior remain unclear. To address these issues, participants were presented simultaneous rapid visual and auditory stimulus sequences under three conditions: attend visual only, attend auditory only, and dual attention (attend both visual and auditory). Performance, measured in terms of response time and perceptual sensitivity (d'), revealed dual-task impairments only in the auditory task. Neural activity, measured by the ERP technique, revealed that both early stage sensory processing and later cognitive processing of the auditory task were affected by dual-task performance, but similar stages of processing of the visual task were not. Critically, individual differences in neural activity at both early and late stages of information processing accurately rank-ordered individuals based on the observed difference in behavioral performance between the single and dual attention conditions. These results reveal relationships between behavioral performance and the neural correlates of both early and late stage information processing that provide key insights into the complex interplay between the brain and behavior when multiple tasks are performed continuously.

TI Spontaneous Mentalizing Predicts the Fundamental Attribution Error SO JOURNAL OF COGNITIVE NEUROSCIENCE LA English DT Article ID MEDIAL PREFRONTAL CORTEX; TEMPORO-PARIETAL JUNCTION; FUNCTIONAL CONNECTIVITY; SOCIAL COGNITION; BRAIN; FMRI; KNOWLEDGE; BEHAVIOR; AUTISM; MINDS AB When explaining the reasons for others' behavior, perceivers often overemphasize underlying dispositions and personality traits over the power of the situation, a tendency known as the fundamental attribution error. One possibility is that this bias results from the spontaneous processing of others' mental states, such as their momentary feelings or more enduring personality characteristics. Here, we use fMRI to test this hypothesis. Participants read a series of stories that described a target's ambiguous behavior in response to a specific social situation and later judged whether that act was attributable to the target's internal dispositions or to external situational factors. Neural regions consistently associated with mental state inference-especially, the medial pFC-strongly predicted whether participants later made dispositional attributions. These results suggest that the spontaneous engagement of mentalizing may underlie the biased tendency to attribute behavior to dispositional over situational forces.

SAMPLE: A total of 46 patients diagnosed with tibia stress fractures. METHODS: The study employed a pre-/postintervention design. Retrospective and prospective information was collected from an electronic health record to obtain patient data. The pre- and postintervention groups were compared on the number of patients diagnosed with tibia stress fractures. Provider adherence to the treatments recommended by the algorithm was assessed by chart audits postintervention. RESULTS: There was a significant increase (87.5%) in tibia stress fracture diagnosis, from 16 preintervention to 30 postintervention. Provider adherence to the LPS&RT was 93.3% postintervention. Common treatments were activity restriction, oral medication, and/or specialty referrals. CONCLUSION: The LPS&RT was an effective, uniform measure to standardize the plan of care for tibia stress fractures in one outpatient clinic.

We evaluated the effect of repeated blast exposures on the integrity of brain DNA and tested the utility of cell-free DNA (CFD) in plasma as a biomarker for the diagnosis and prognosis of blast-induced polytrauma. The results revealed time-dependent breakdown in cellular DNA in different brain regions, with the maximum damage at 24 h post-blast exposures. CFD levels in plasma showed a significant transient increase, which was largely independent of the timing and severity of brain DNA damage; maximum levels were recorded at 2?h after repeated blast exposure and returned to baseline at 24?h. A positive correlation was observed between the righting reflex time and CFD level in plasma at 2?h after blast exposure. Brain DNA damage subsequent to repeated blast was associated with decreased mitochondrial membrane potential, increased release of cytochrome C, and up-regulation of caspase-3, all of which are indicative of cellular apoptosis. Shock-wave-induced DNA damage and initiation of mitochondrial-driven cellular apoptosis in the brain after repeated blast exposures indicate that therapeutic strategies directed toward inhibition of DNA damage or instigation of DNA repair may be effective countermeasures.

TI Long-term silencing of autoimmune diabetes and improved life expectancy by a soluble pHLA-DR4 chimera in a newly-humanized NOD/DR4/B7 mouse SO HUMAN VACCINES & IMMUNOTHERAPEUTICS LA English DT Article DE HLA-peptide chimera; HLA-humanized NOD mouse; T1D prevention and stabilization ID MOLECULE B7-1; II CHIMERA; BETA-CELLS; T-CELLS; TYPE-1; MICE; REVERSAL; MELLITUS; EPITOPE; ISLETS AB Several human MHC class II (HLA) molecules are strongly associated with high incidence of autoimmune diseases including type 1 diabetes (T1D). The HLA-humanized mice may thus represent valuable tools to test HLA-based vaccines and therapeutics for human autoimmune diseases. Herein, we have tested the therapeutic potential of a soluble HLA-DR4-GAD65(271-280) (hu DEF-GAD65) chimera of human use in a newly-generated NOD/DR4/B7 double transgenic (dTg) mouse that develops spontaneously an accelerated T1D regardless the gender. The NOD/DR4/B7 dTg mice generated by a two-step crossing protocol express the HLA-DR*0401 molecules on 20% of antigen presenting cells, the human B7 molecules in pancreas, and HLA-DR4/GAD65-specific T-cells in the blood. Some 75% of pre-diabetic NOD/DR4/B7 dTg mice treated with hu DEF-GAD65 chimera remained euglycemic and showed a stabilized pancreatic insulitis 6 months after treatment. The 25% non responders developing hyperglycemia survived 3-4 months longer than their untreated littermates. T1D prevention by this reagent occurred by a Th2/TR-1 polarization in the pancreas. This study strongly suggests that the use of soluble pHLA reagents to suppress/stabilize the T1D progression and to extend the life expectancy in the absence of side effects is an efficient and safe therapeutic approach.
