TI Preparation and Testing of Impedance-based Fluidic Biochips with RTgill-W1 Cells for Rapid Evaluation of Drinking Water Samples for Toxicity SO JOVE-JOURNAL OF VISUALIZED EXPERIMENTS LA English DT Article DE Environmental Sciences; Issue 109; Fish cells; impedance; sensors; biochip; water toxicity; ECIS; monolayer; field-portable ID CYTOTOXICITY; BIOSENSORS AB This manuscript describes how to prepare fluidic biochips with Rainbow trout gill epithelial (RTgill-W1) cells for use in a field portable water toxicity sensor. A monolayer of RTgill-W1 cells forms on the sensing electrodes enclosed within the biochips. The biochips are then used for testing in a field portable electric cell-substrate impedance sensing (ECIS) device designed for rapid toxicity testing of drinking water. The manuscript further describes how to run a toxicity test using the prepared biochips. A control water sample and the test water sample are mixed with pre-measured powdered media and injected into separate channels of the biochip. Impedance readings from the sensing electrodes in each of the biochip channels are measured and compared by an automated statistical software program. The screen on the ECIS instrument will indicate either "Contamination Detected" or "No Contamination Detected" within an hour of sample injection. Advantages are ease of use and rapid response to a broad spectrum of inorganic and organic chemicals at concentrations that are relevant to human health concerns, as well as the long-term stability of stored biochips in a ready state for testing. Limitations are the requirement for cold storage of the biochips and limited sensitivity to cholinesterase-inhibiting pesticides. Applications for this toxicity detector are for rapid field-portable testing of drinking water supplies by Army Preventative Medicine personnel or for use at municipal water treatment facilities.

TI Self-reported side-effects associated with use of dietary supplements in an armed forces population SO DRUG TESTING AND ANALYSIS LA English DT Article DE protein supplements; combination products; body mass index; physical fitness ID MILITARY PERSONNEL; SAFETY; SOLDIERS AB Approximately 60-70% of Armed Forces personnel consume a dietary supplement (DS) at least once a week and there have been numerous reports of severe adverse events among DS users. This study assessed patterns of DS use and self-reported side-effects among 4400 Armed Forces personnel using a paper-and-pencil survey. Multivariable logistic regression was used to examine associations between patterns of DS use and self-reported side-effects. Sixty-nine percent of personnel surveyed reported using a DS. Seven percent of DS users reported experiencing abnormal heart beats, 6% tremors, 5% stomach pain, 3% dizziness, and 3% numbness/tingling and they believed these symptoms were associated with the use of DS. After adjustment for use of other DS classes, total supplement use, and demographic characteristics, protein supplement users were more likely than non-users to report numbness/tingling; combination product users were more likely to report experiencing abnormal heart beats, stomach pain, dizziness, tremors, and numbness/tingling; and users of purported steroid analogues were more likely to report dizziness. Use of more than one DS per week was associated with an increased likelihood of reporting side-effects. Respondents with a higher body mass index were more likely to report side-effects. Further research is necessary to determine whether self-reported side-effects associated with multiple DS use and some DS classes impact the long-term health or performance of service members. Surveillance of military populations using surveys like this one may provide a method for detecting adverse health events of DS before they are apparent in the civilian population.

TI Excitation intensity dependence of photoluminescence from monolayers of MoS2 and WS2/MoS2 heterostructures SO 2D MATERIALS LA English DT Article DE Raman; molybdenum disulfide; CVD; excitation intensity dependence; heterostructure; exciton; trion ID TRANSITION-METAL DICHALCOGENIDES; MOLYBDENUM-DISULFIDE; LAYER MOS2; TRIONS AB A detailed study of the excitation dependence of the photoluminescence (PL) from monolayers of MoS2 and WS2/MoS2 heterostructures grown by chemical vapor deposition on Si substrates has revealed that the luminescence from band edge excitons from MoS2 monolayers shows a linear dependence on excitation intensity for both above band gap and resonant excitation conditions. In particular, a band separated by similar to 55 meV from the A exciton, referred to as the C band, shows the same linear dependence on excitation intensity as the band edge excitons. A band similar to the C band has been previously ascribed to a trion, a charged, three-particle exciton. However, in our study the C band does not show the 3/2 power dependence on excitation intensity as would be expected for a three-particle exciton. Further, the PL from the MoS2 monolayer in a bilayer WS2/MoS2 heterostructure, under resonant excitation conditions where only the MoS2 absorbs the laser energy, also revealed a linear dependence on excitation intensity for the C band, confirming that its origin is not due to a trion but instead a bound exciton, presumably of an unintentional impurity or a native point defect such as a sulfur vacancy. The PL from the WS2/MoS2 heterostructure, under resonant excitation conditions also showed additional features which are suggested to arise from the interface states at the heteroboundary. Further studies are required to clearly identify the origin of these features.

TI Wavefunction collapse through backaction of counting weakly interacting photons SO JOURNAL OF MATHEMATICAL PHYSICS LA English DT Article ID VON-NEUMANN MEASUREMENT; QUANTUM; DECOHERENCE; MODELS AB We apply the formalism of quantum measurement theory to the idealized measurement of the position of a particle with an optical interferometer, finding that the backaction of counting entangled photons systematically collapses the particle's wave-function toward a narrow Gaussian wavepacket at the location x(est) determined by the measurement without appeal to environmental decoherence or other spontaneous collapse mechanism. Further, the variance in the particle's position, as calculated from the post-measurement wavefunction, agrees precisely with shot-noise limited uncertainty of the measured x(est). Both the identification of the absolute square of the particle's initial wavefunction as the probability density for x(est) and the de Broglie hypothesis emerge as consequences of interpreting the intensity of the optical field as proportional to the probability of detecting a photon. Linear momentum information that is encoded in the particle's initial wavefunction survives the measurement, and the pre-measurement expectation values are preserved in the ensemble average.

In addition, the purposes were to compare the concentration maximum (Cmax), time to maximum concentration (Tmax), and odds of ROSC. Methods: This was a between-subjects, prospective experimental study. Yorkshire swine (N=21) were randomly assigned to 1 of 3 groups: TIO, IV, or control groups. The swine were anesthetized and instrumented, and then cardiac arrest was induced and sustained for 2 minutes. Cardiopulmonary resuscitation was initiated and continued for 2 minutes. Vasopressin was then administered via the TIO or IV route. Blood samples were collected for 4 minutes to determine the Cmax and Tmax of vasopressin. Concentration maximum and Tmax were calculated by use of liquid chromatography with mass spectrometry. Results: There was no difference in ROSC between the TIO and IV groups (P=.63). The Cmax of vasopressin was significantly higher in the IV group compared to the TIO group (P=.017). However, there was no significant difference in ROSC, time to ROSC, or Tmax between groups (P>.05). All subjects had ROSC in both the IV and TIO groups, and none had ROSC in the control group. There was 225 times greater chance of survival for both the IV and TIO groups compared to the control group. Conclusion: The data support that the TIO is an effective route for vasopressin in a cardiac arrest model. Published by Elsevier Inc.

TI Gardony Map Drawing Analyzer: Software for quantitative analysis of sketch maps SO BEHAVIOR RESEARCH METHODS LA English DT Article DE Sketch maps; Cognitive mapping; Spatial memory; Mental models ID VISUAL WORKING-MEMORY; BIDIMENSIONAL REGRESSION; ENVIRONMENTS; PERFORMANCE; ABILITIES; LOCATION AB Sketch maps are effective tools for assessing spatial memory. However, despite their widespread use in cognitive science research, sketch map analysis techniques remain unstandardized and carry limitations. In the present article, we present the Gardony Map Drawing Analyzer (GMDA), an open-source software package for sketch map analysis. GMDA combines novel and established analysis techniques into a graphical user interface that permits rapid computational sketch map analysis. GMDA calculates GMDA-unique measures based on pairwise comparisons between landmarks, as well as bidimensional regression parameters (Friedman & Kohler, 2003), which together reflect sketch map quality at two levels: configural and individual landmark. The configural measures assess the overall landmark configuration and provide a whole-map analysis. Individual landmark measures, introduced in GMDA, assess individual landmark placement and indicate how individual landmarks contribute to the configural scores. Together, these measures provide a more complete psychometric picture of sketch map analysis, allowing for comparisons between sketch maps and between landmarks. The calculated measures reflect specific and cognitively relevant aspects of interlandmark spatial relationships, including distance and angular representation. GMDA supports complex environments (up to 48 landmarks) and two software modes that capture aspects of maps not addressed by existing techniques, such as landmark size and shape variation and interlandmark containment relationships. We describe the software and its operation and present a formal specification of calculation procedures for its unique measures. We then validate the software by demonstrating the capabilities and reliability of its measures using simulation and experimental data. The most recent version of GMDA is available at www.aarongardony.com/tools/map-drawing-analyzer.

TI A history of low back pain affects pelvis and trunk coordination during a sustained manual materials handling task SO JOURNAL OF SPORT AND HEALTH SCIENCE LA English DT Article DE Lifting; Lowering; Occupational biomechanics; Relative phase; Relative phase variability ID DYNAMICAL-SYSTEMS APPROACH; RISK-FACTORS; WALKING; INJURY; VARIABILITY; WORKERS AB Purpose: The purpose of this study was to compare the coordination between the trunk and the pelvis during a sustained asymmetric repetitive lifting task between a group with a history of low back pain (LBP; HBP) and a group with no history of LBP (NBP). Methods: Volunteers lifted a 11-kg box from ankle height in front to a shelf 45 degrees off-center at waist height, and lowered it to the start position at 12 cycles/min for 10 min. Lifting side was alternated during the trial. Continuous relative phase was used to calculate coordination between the pelvis and trunk rotation at the beginning (Min 1), middle (Min 5), and end of the bout (Min 9). Results: While there were no main effects for group, a significant interaction between time and group indicated that, in the frontal plane, the NBP group coordination was more anti-phase toward the end of the bout, with no such differences for the HBP group. Analysis of sagittal-axial (bend and twist) coordination revealed the HBP group coordination was more in-phase at the end of the bout over the entire cycle and for the lifting phase alone, with no such differences for the NBP group. Conclusion: Differences between groups demonstrate residual consequences of LBP in an occupational scenario, even though the HBP group was pain-free for >6 months prior to data collection. More in-phase coordination in the HBP group may represent a coordination pattern analogous to "guarded gait" which has been observed in other studies, and may lend insight as to why these individuals are at increased risk for re-injury.

In the present work, an analytical model has been developed to predict the elastic modulus, the yield stress, the failure stress, and the failure strain taking into consideration the effect of temperatures for precipitation-hardenable Al-Mg-Cu-Si Alloys (Al-A319 alloys). In addition, other important mechanical properties of Al-A319 alloys including the strain hardening exponent, the strength coefficient, and the ductility parameter can be estimated using the current model. It is demonstrated that the prediction results based on the proposed model are in good agreement with those obtained experimentally in Al-A319 alloys in the as-cast condition and after W and T7 heat treatments.

TI What Patients Really Want: Optimizing the Military Preoperative Evaluation Clinic SO MILITARY MEDICINE LA English DT Article ID WAITING-TIMES AB The idea of the preoperative anesthesia clinic as a means of examining and treating the patient so that he will arrive in the operating theater as strong and healthy as possible is well established in practice and literature. However, problems in clinic design and execution often result in high patient waiting times, decreased patient and staff satisfaction, decreased patient capacity, and high clinic costs. Although the details of clinic design, outcomes, and satisfaction have been extensively evaluated at civilian hospitals, we have not found corresponding literature addressing these issues specifically within military preoperative evaluation clinics. We find that changing to an appointment-based (versus walk-in) system and eliminating data collection step redundancies will likely result in lower wait times, higher satisfaction, lower per patient costs, and a more streamlined and resource-efficient structure.

Purpose: To determine if ETAP would reduce unintentional MSIs in a group of 101st Airborne Division (Air Assault) Soldiers. Methods: ETAP-trained noncommissioned led physical training. 1,720 Soldiers were enrolled (N = 1,136 experimental group [EXP], N = 584 control group [CON]) with injuries tracked before and after initiation of ETAP. The International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes were analyzed and described the anatomic locations, anatomic sub-locations, onset, and injury types. McNemar tests compared the proportions of injured subjects within each group. Results: There was a significant reduction in the proportion of Soldiers with preventable MSIs in the EXP (pre: 213/1,136 (18.8%), post: 180/1,136 (15.8%), p = 0.041) but not in the CON. In addition, there was a significant reduction in stress fractures in the EXP (pre: 14/1,136 (1.2%), post: 5/1,136 (0.4%), p = 0.022) but no significant differences in the CON. Conclusion: The current analysis demonstrated that ETAP reduces preventable MSIs in garrison. The capability of ETAP to reduce injuries confirms the vital role of a scientifically designed training program on force readiness and health.

TI Postdeployment Respiratory Health Care Encounters Following Deployment to Kabul, Afghanistan: A Retrospective Cohort Study SO MILITARY MEDICINE LA English DT Article ID US MILITARY PERSONNEL; MEDICAL ENCOUNTERS; PARTICULATE MATTER; SOUTHWEST ASIA; SYMPTOMS; IRAQ; PREVALENCE; EXPOSURE; SOLDIERS; WARRIOR AB Inhalational hazards are numerous in operational environments. A retrospective cohort study was conducted to investigate associations between deployment to Kabul, Afghanistan and subsequent respiratory health among U.S. military personnel. The study population consisted of personnel who deployed to Kabul, select Operation Enduring Freedom locations, personnel stationed in the Republic of Korea, and U.S.-stationed personnel. Incidence rate ratios (IRRs) were estimated for respiratory symptoms, signs, and ill-defined conditions, asthma, and chronic obstructive pulmonary disease. A significantly elevated rate of symptoms, signs, and ill-defined conditions was observed among Kabul-deployed personnel compared to personnel deployed or stationed in Bagram (IRR 1.12; 95% confidence interval [CI], 1.05-1.19), Republic of Korea (IRR 1.20; 95% CI, 1.10-1.31), and the United States (IRR 1.52; 95% CI, 1.43-1.62). A statistically elevated rate of asthma was observed among personnel deployed to Kabul, relative to U.S.-stationed personnel (IRR 1.61; 95% CI, 1.22-2.12). Statistically significant rates were not observed for chronic obstructive pulmonary disease among Kabul-deployed personnel compared to other study groups. These findings suggest that deployment to Kabul is associated with an elevated risk of postdeployment respiratory symptoms and new-onset asthma.

TI Short-Term Outcomes and Complications of Damage Control and Definitive Laparotomy in Deployed Combat Environments: 2002 to 2011 SO MILITARY MEDICINE LA English DT Article ID CONTROL SURGERY; MANAGEMENT; BATTLEFIELD; CASUALTIES; SURVIVAL; INJURY; TRAUMA; TIME AB Introduction: Damage control laparotomy (DCL) in an austere environment is an evolving surgical modality. Methods: A retrospective evaluation of all patients surviving 24 hours who underwent a laparotomy from 2002 to 2011 in Iraq and Afghanistan was performed. DCL was defined as a patient undergoing laparotomy at two distinct North American Treaty Organization (NATO) Role 2 or 3 medical treatment facilities (MTFs); a NATO Roles 2 and 3 MTFs, and/or having the International Classification of Diseases, 9th Revision, Clinical Modification procedure code 54.12, for reopening of recent laparotomy site. Definitive laparotomy (DL) was defined as patients undergoing one operative procedure at one NATO Role 2 or 3 MTF. Demographic data including injury severity scores, hematological transfusion, mortality, intraperitoneal or retroperitoneal operative interventions, and complications were compared. Results: DCL composed of 26.5% (n = 331) of all 1,248 laparotomies performed between March 2002 and September 2011. Total intra-abdominal, acute respiratory distress syndrome, and thromboembolic complications for DCL versus DL were 8.5% and 5.6% (p = 0.07), 2.1% and 0.8% (p = 0.06), and 1.5% and 0.7% (p = 0.17), respectively. Theater discharge mortality from DCL and DL were 1.5% (n = 5), and 1.4% (n = 13) (p = 0.90), respectively. Conclusions: In conclusion, excluding deaths with the first 24 hours, DCL and DL had comparable mortality and complication rates at NATO Roles 2 and 3 MTFs.

He was diagnosed with classic juvenile (type III) pityriasis rubra pilaris (PRP) and treated with oral isotretinoin for 6 months. His skin findings resolved quickly during the treatment period, with residual postinflammatory hypopigmentation resolving within a year. PRP is rare in pediatric patients and standard recommended treatment algorithms for this population are not currently available. Diagnostic and treatment guidelines for PRP are based almost exclusively on case reports or case series, most of which focus on adult patients.

TI A fiber optic, ultraviolet light-emitting diode-based, two wavelength fluorometer for monitoring reactive adsorption SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article ID PHOTOLUMINESCENCE PROPERTIES; ZIRCONIUM HYDROXIDE; SURFACE-CHEMISTRY; SULFUR-DIOXIDE; REMOVAL; THIOL; FILMS AB Construction and use of an ultraviolet light-emitting diode-based fluorometer for measuring photoluminescence (PL) from powder samples with a fiber optic probe is described. Fluorescence at two wavelengths is detected by miniature photomultiplier tubes, each equipped with a different band pass filter, whose outputs are analyzed by a microprocessor. Photoluminescent metal oxides and hydroxides, and other semiconducting nanoparticles, often undergo changes in their emission spectra upon exposure to reactive gases, and the ratio of the PL intensities at two wavelengths is diagnostic of adsorption. Use of this instrument for reactive gas sensing and gas filtration applications is illustrated by measuring changes in the PL ratio for zirconium hydroxide and zinc oxide particles upon exposure to air containing low concentrations of sulfur dioxide.

Pati, Shibani TI Platelets regulate vascular endothelial stability: assessing the storage lesion and donor variability of apheresis platelets SO TRANSFUSION LA English DT Article ID TRAUMATIC BRAIN-INJURY; FRESH-FROZEN PLASMA; LARGE ANIMAL-MODEL; 22 DEGREES C; HEMORRHAGIC-SHOCK; MOLECULAR-BASIS; RESUSCITATION; PERMEABILITY; TRANSFUSION; MAINTENANCE AB BACKGROUNDIn current blood banking practices, platelets (PLTs) are stored in plasma at 22 degrees C, with gentle agitation for up to 5 days. To date, the effects of storage and donor variability on PLT regulation of vascular integrity are not known. STUDY DESIGN AND METHODSIn this study, we examined the donor variability of leukoreduced fresh (Day 1) or stored (Day 5) PLTs on vascular endothelial barrier function in vitro and in vivo. In vitro, PLT effects on endothelial cell (EC) monolayer permeability were assessed by analyzing transendothelial electrical resistances (TEER). PLT aggregation, a measure of hemostatic potential, was analyzed by impedance aggregometry. In vivo, PLTs were investigated in a vascular endothelial growth factor A (VEGF-A)-induced vascular permeability model in NSG mice, and PLT circulation was measured by flow cytometry. RESULTSTreatment of endothelial monolayers with fresh Day 1 PLTs resulted in an increase in EC barrier resistance and decreased permeability in a dose-dependent manner. Subsequent treatment of EC monolayers with Day 5 PLTs demonstrated diminished vasculoprotective effects. Donor variability was noted in all measures of PLT function. Day 1 PLT donors were more variable in their effects on TEER than Day 5 PLTs. In mice, while all PLTs regardless of storage time demonstrated significant protection against VEGF-A-induced vascular leakage, Day 5 PLTs exhibited reduced protection when compared to Day 1 PLTs. Day 1 PLTs demonstrated significant donor variability against VEGF-A-challenged vascular leakage in vivo. Systemic circulating levels of Day 1 PLTs were higher than those of Day 5 PLTs CONCLUSIONSIn vitro and in vivo, Day 1 PLTs are protective in measures of vascular endothelial permeability. Donor variability is most prominent in Day 1 PLTs. A decrease in the protective effects is found with storage of the PLT units between Day 1 and Day 5 at 22 degrees C, thereby suggesting that Day 5 PLTs are diminished in their ability to attenuate vascular endothelial permeability.

In this study, we compared the effects of room temperature (22 degrees C) stored and (4 degrees C) stored PLTs on the regulation of vascular endothelial cell (EC) permeability in vitro and in vivo. STUDY DESIGN AND METHODSDay 1, Day 5, and Day 7 leukoreduced apheresis PLTs stored at 4 or 22 degrees C were studied in vitro and in vivo. In vitro, PLT effects on EC permeability and barrier function, adhesion, and impedance aggregometry were investigated. In vivo, using a mouse model of vascular leak, attenuation of vascular leak and circulating PLT numbers were measured. RESULTSTreatment of EC monolayers with Day 5 or Day 7 PLTs, stored at both 22 degrees C and 4 degrees C, resulted in similar decreases in EC permeability on average. However, analysis of individual samples revealed significant variation that was donor dependent. Additional in vitro measurements revealed a decrease in inflammatory mediators, nonspecific PLT-endothelial aggregation and attenuated loss of aggregation over time to TRAP, ASPI, ADP, and collagen with 4 degrees C storage. In mice, while 22 degrees C and 4 degrees C PLTs both demonstrated significant protection against vascular endothelial growth factor A (VEGF-A)-induced vascular leak 22 degrees C PLTs exhibited increased protection compared to 4 degrees C PLTs. Systemic circulating levels of 4 degrees C PLTs were decreased compared to 22 degrees C PLTs. CONCLUSIONSIn vitro, 4 degrees C-stored PLTs exhibit a greater capacity to inhibit EC permeability than 22 degrees C-stored PLTs. In vivo, 22 degrees C PLTs provide superior control of vascular leak induced by VEGF-A. This discrepancy may be due to increased clearance of 4 degrees C PLTs from the systemic circulation.

TI Bioenergetic profiling of platelet mitochondria during storage: 4 degrees C storage extends platelet mitochondrial function and viability SO TRANSFUSION LA English DT Article ID CHILLED BLOOD-PLATELETS; HEMOSTATIC EFFECTIVENESS; VIABLE PLATELETS; COLD-STORAGE; WHOLE-BLOOD; AGGREGATION; TRANSFUSION; OXYGEN; RESPIRATION; REACTIVITY AB BACKGROUNDPlatelets (PLTs) are stored at room temperature (RT) to preserve in vivo circulation time, but PLT quality is degraded. The PLT storage lesion is mitigated by refrigeration, but questions remain regarding effects of cold storage (4 degrees C) on mitochondrial function. Mitochondrial reactive oxygen species (ROS) generation may adversely affect PLT function and viability during storage, and refrigeration may mitigate these effects. STUDY DESIGN AND METHODSPLTs were stored under two temperature conditions (RT, 20-24 degrees C; or 4 degrees C, 1-6 degrees C) and four storage durations (baseline [BL] and Days 3, 5, and 7). Mitochondrial respiration and maximal oxygen utilization were assessed with high-resolution respirometry. Mitochondrial ROS generation was assessed using a superoxide stain. Rotational thromboelastometry (ROTEM) was performed at BL and on Day 5 to assess PLT function. Collagen-induced PLT aggregation was measured by impedance aggregometry. RESULTSMitochondrial ROS in 4 degrees C-stored samples were lower compared to RT and retained a greater capacity to generate ROS after activation. Mitochondrial respiration and maximal mitochondrial utilization was conserved in PLTs stored at 4 degrees C. ROTEM data demonstrated that net maximum clot firmness was higher in 4 degrees C samples compared to RT and prevented fibrinolysis. The aggregation response to collagen was preserved in the 4 degrees C samples versus RT-stored PLTs. Aggregation impairment correlated well with attenuated mitochondrial respiration and elevated production of intracellular mitochondrial ROS in the RT PLTs. CONCLUSIONMitochondrial damage and ROS production may contribute to loss of PLT viability during storage, whereas cold storage is known to preserve PLT function. Here we demonstrate that 4 degrees C storage results in less oxidant stress and preserves mitochondrial function and potential compared to RT. C1 [Bynum, James A.; Meledeo, M.

TI Treatment of blood with a pathogen reduction technology using ultraviolet light and riboflavin inactivates Ebola virus in vitro SO TRANSFUSION LA English DT Article ID HERPES-SIMPLEX VIRUS; TRANSFUSION-TRANSMITTED MALARIA; NORMAL HUMAN-FIBROBLASTS; ENHANCED REACTIVATION; PHOTOCHEMICAL INACTIVATION; IRRADIATED ADENOVIRUS; DNA-DAMAGE; PLATELET; PLASMA; INFECTION AB BACKGROUNDTransfusion of plasma from recovered patients after Ebolavirus (EBOV) infection, typically called convalescent plasma, is an effective treatment for active disease available in endemic areas, but carries the risk of introducing other pathogens, including other strains of EBOV. A pathogen reduction technology using ultraviolet light and riboflavin (UV+RB) is effective against multiple enveloped, negative-sense, single-stranded RNA viruses that are similar in structure to EBOV. We hypothesized that UV+RB is effective against EBOV in blood products without activating complement or reducing protective immunoglobulin titers that are important for the treatment of Ebola virus disease (EVD). STUDY DESIGN AND METHODSFour in vitro experiments were conducted to evaluate effects of UV+RB on green fluorescent protein EBOV (EBOV-GFP), wild-type EBOV in serum, and whole blood, respectively, and on immunoglobulins and complement in plasma. Initial titers for Experiments 1 to 3 were 4.21 log GFP units/mL, 4.96 log infectious units/mL, and 4.23 log plaque-forming units/mL. Conditions tested in the first three experiments included the following: 1EBOV-GFP plus UV+RB; 2EBOV-GFP plus RB only; 3EBOV-GFP plus UV only; 4EBOV-GFP without RB or UV; 5virus-free control plus UV only; and 6virus-free control without RB or UV. RESULTSUV+RB reduced EBOV titers to nondetectable levels in both nonhuman primate serum (2.8- to 3.2-log reduction) and human whole blood (3.0-log reduction) without decreasing protective antibody titers in human plasma. CONCLUSIONOur in vitro results demonstrate that the UV+RB treatment efficiently reduces EBOV titers to below limits of detection in both serum and whole blood. In vivo testing to determine whether UV+RB can improve convalescent blood product safety is indicated.

National and International Blood Bank authorities have noted that the US Army research and development efforts in providing new blood products and improving blood safety operate on the cutting edge of technology and are transformational for the global blood industry. Over the past 14 years, the Army has transformed how blood support is provided and improved the survival rate of casualties. Almost every product or process developed by or for the military has found an application in treating civilian patients. Conflicts have many unwanted consequences; however, in times of conflict, one positive aspect is the identification of novel solutions to improve the safety and efficacy of the blood supply.

There are significant logistic factors that limit the ability to deliver plasma where needed in austere environments, such as the battlefield or during a significant civilian emergency. While some countries have access to more logistically supportable dried plasma, there is no such product approved for use in the United States. There is a clear need for a Food and Drug Administration (FDA)-approved dried plasma for military and emergency-preparedness uses, as well as for civilian use in remote or austere settings. The Department of Defense (DoD) and Biomedical Advanced Research and Development Authority are sponsoring development of three dried plasma products, incorporating different technologic approaches and business models. At the same time, the DoD is sponsoring prospective, randomized clinical studies on the prehospital use of plasma. These efforts are part of a coordinated program to provide a dried plasma for military and civilian applications and to produce additional information on plasma use so that, by the time we have an FDA-approved dried plasma, we will better understand how to use it.

Reifman, Jaques TI Muscle Oxygen Saturation Improves Diagnostic Association Between Initial Vital Signs and Major Hemorrhage: A Prospective Observational Study SO ACADEMIC EMERGENCY MEDICINE LA English DT Article ID TISSUE; TRANSFUSION; PREDICTS; TRAUMA AB ObjectivesDuring initial assessment of trauma patients, vital signs do not identify all patients with life-threatening hemorrhage. We hypothesized that a novel vital sign, muscle oxygen saturation (SmO2), could provide independent diagnostic information beyond routine vital signs for identification of hemorrhaging patients who require packed red blood cell (RBC) transfusion. MethodsThis was an observational study of adult trauma patients treated at a Level I trauma center. Study staff placed the CareGuide 1100 tissue oximeter (Reflectance Medical Inc., Westborough, MA), and we analyzed average values of SmO2, systolic blood pressure (sBP), pulse pressure (PP), and heart rate (HR) during 10 minutes of early emergency department evaluation. We excluded subjects without a full set of vital signs during the observation interval. The study outcome was hemorrhagic injury and RBC transfusion 3 units in 24 hours (24-hr RBC 3). To test the hypothesis that SmO2 added independent information beyond routine vital signs, we developed one logistic regression model with HR, sBP, and PP and one with SmO2 in addition to HR, sBP, and PP and compared their areas under receiver operating characteristic curves (ROC AUCs) using DeLong's test. ResultsWe enrolled 487 subjects; 23 received 24-hr RBC 3. Compared to the model without SmO2, the regression model with SmO2 had a significantly increased ROC AUC for the prediction of 3 units of 24-hr RBC volume, 0.85 (95% confidence interval [CI], 0.75-0.91) versus 0.77 (95% CI, 0.66-0.86; p < 0.05 per DeLong's test). Results were similar for ROC AUCs predicting patients (n = 11) receiving 24-hr RBC 9. ConclusionsSmO(2) significantly improved the diagnostic association between initial vital signs and hemorrhagic injury with blood transfusion. This parameter may enhance the early identification of patients who require blood products for life-threatening hemorrhage.

The potential of MoS2 mono- and few-layers in electronics, opto electronics, and flexible devices requires the fundamental understanding of their properties as a function of strain. While previous reports have studied mechanically exfoliated flakes, tensile strain experiments on chemical vapor deposition (CVD)-grown few-layered MoS2 have not been examined hitherto, although CVD is a state of the art synthesis technique with clear potential for scale-up processes. In this report, we used CVD-grown terrace MoS2 layers to study how the number and size of the layers affected the physical properties under uniaxial and biaxial tensile strain. Interestingly, we observed significant shifts in both the Raman in-plane mode (as high as -5.2 cm(-1)) and photoluminescence (PL) energy (as high as -88 meV) for the few-layered MoS2 under similar to 1.5% applied uniaxial tensile strain when compared to monolayers and few-layers of MoS2 studied previously. We also observed slippage between the layers which resulted in a hysteresis of the Raman and PL spectra during further applications of strain. Through DFT calculations, we contended that this random layer slippage was due to defects present in CVD-grown materials. This work demonstrates that CVD-grown few-layered MoS2 is a realistic, exciting material for tuning its properties under tensile strain.

TI Vertical 2D/3D Semiconductor Heterostructures Based on Epitaxial Molybdenum Disulfide and Gallium Nitride SO ACS NANO LA English DT Article DE 2D material heterostructures; transition metal dichalcogenides; MoS2; van der Waals epitaxy; GaN; conductive atomic force microscopy; vertical transport ID CHEMICAL-VAPOR-DEPOSITION; HEXAGONAL BORON-NITRIDE; SINGLE-LAYER MOS2; MONOLAYER MOS2; ATOMIC LAYERS; TRANSISTORS; GRAPHENE; GROWTH AB When designing semiconductor heterostructures, it is expected that epitaxial alignment will facilitate low-defect interfaces and efficient vertical transport. Here, we report lattice-matched epitaxial growth of molybdenum disulfide (MoS2) directly on gallium nitride (GaN), resulting in high-quality, unstrained, single-layer MoS2 with strict registry to the GaN lattice. These results present a promising path toward the implementation of high-performance electronic devices based on 2D/3D vertical heterostructures, where each of the 3D and 2D semiconductors is both a template for subsequent epitaxial growth and an active component of the device. The MoS2 monolayer triangles average 1 mu m along each side, with monolayer blankets (merged triangles) exhibiting properties similar to that of single-crystal MoS2 sheets. Photoluminescence, Raman, atomic force microscopy, and X-ray photoelectron spectroscopy analyses identified monolayer MoS2 with a prominent 20-fold enhancement of photoluminescence in the center regions larger triangles. The MoS2/GaN structures are shown to electrically conduct in the out-of-plane direction, confirming the potential of directly synthesized 2D/3D semiconductor heterostructures for vertical, current flow. Finally, we estimate a MoS2/GaN contact resistivity to be less than 4 Omega.cm(2) and current spreading in the MoS2 monolayer of approximately 1 mu m in diameter.

MethodsTo vary AMS, we manipulated ambient oxygen, barometric pressure, and exercise duration. Thirty-six subjects were tested before, during and after 8 h exposures in (1) normobaric normoxia (NN; 300m elevation equivalent); (2) normobaric hypoxia (NH; 4400m equivalent); and (3) hypobaric hypoxia (HH; 4400m equivalent). After a passive 15 min ascent, each subject participated in either 10 or 60min of cycling exercise at 50% of heart rate reserve. We measured tissue absorption and scattering via radio-frequency near-infrared spectroscopy (NIRS), optic nerve sheath diameter (ONSD) via ultrasound, and AMS symptoms before, during, and after environmental exposures. ResultsWe observed significant increases in NIRS tissue scattering of 0.350.11cm(-1) (P=0.001) in subjects with AMS (i.e., AMS+), consistent with mildly increased cerebral edema. We also noted a small, but significant increase in total hemoglobin concentrations with AMS+, 3.2 +/- 0.8molL(-1) (P<0.0005), consistent with increased cerebral perfusion. No effect of exercise duration was found, nor did we detect differences between NH and HH. ONSD assays documented a small but significant increase in ONSD (0.11 +/- 0.02mm; P<0.0005) with AMS+, suggesting mildly elevated ICP, as well as further increased ONSD with longer exercise duration (P=0.005). ConclusionIn AMS+, we found evidence of cerebral edema, elevated cerebral perfusion, and elevated ICP. The observed changes were small but consistent with the reversible nature of AMS.

CASE: A woman with history of benign metastasizing leiomyoma underwent medical treatment for 5 years with ulipristal acetate. Endometrial biopsies were performed at established intervals to monitor for intraepithelial neoplasia or progesterone receptor modulator associated endometrial changes (PAECs). The patient tolerated UPA therapy well; there was no evidence of hyperplasia or proliferative changes associated with progesterone-associated endometrial changes. CONCLUSION: In this case prolonged exposure to ulipristal acetate did not result in premalignant or malignant endometrial pathology.

Key to our strategy is to generate acetyl nitrate at 30-35 degrees C in the presence of the reactant melamine. The main advantage of our procedure is that it utilized a homogeneous reagent and a homogeneous reactant solution. This allowed control of the reaction exotherm much easier. The robustness of this process is successfully demonstrated by producing DNAM in multikilogram quantities using a 20 L reactor.

We have grown films of Cr2O3 on top of graphite and graphene by pulsed laser deposition that shows this crucial functionality. We demonstrate that the Cr2O3 films are magnetoelectric by poling them in combined electric and magnetic fields and then using magnetic force microscopy to observe spontaneous surface domain structure as a function of poling field. In addition, we show that the electric field created by a conducting AFM tip can be used to write magnetic patterns in the film that demonstrate the kind of continuous magnetoelectric control needed for a prototype spin-FET.

The approach takes into account both geometric corrections with data on local topography and photometric conjunctions using our simple photometric model. New mosaics obtained with the technique allow more reliable studies of structural and chemical characteristics of the lunar surface. This approach has been applied to analyze the photometric anomaly (21.6 S, 17.7 W, similar to 40 km in size) in Mare Nubium detected earlier with our Earth-based observations. For each point of the scene the parameters were calculated using the least-square method for several tens of source WAC images. Clementine mosaics also were used in the analysis, e.g., in order to estimate the parameter of maturity degree I-s/FeO. The anomaly has low FeO and TiO2 abundance and reveals a higher slope of the phase function than surroundings. Thermal data from LRO Diviner measurements do not show anomalies in this region. We consider this area as a shallow flooding of an elevated formation of highland composition, the material of which could have been excavated and mixed up with upper layers of the lunar surface through meteoroid impacts. The anomalous behavior of the phase function can be explained by the difference of surface structure in the anomaly and surrounding regions on the scale of less than several centimeters. This may be due to larger quantities of small fragments of rocks and clumps on the surface and/or the presence of agglomerates having open structure. (c) 2016 Elsevier Ltd. All rights reserved.

TI Exercise Testing: Who, When, and Why? SO PM&R LA English DT Review ID AMERICAN-HEART-ASSOCIATION; SCIENTIFIC STATEMENT; FUNCTIONAL-CAPACITY; CLINICAL CARDIOLOGY; CARDIOPULMONARY; REHABILITATION; PREVENTION; COMMITTEE; FAILURE; PROTOCOLS AB There are different modalities of exercise testing that can provide valuable information to physicians about patient and athlete fitness and cardiopulmonary status. Cardiopulmonary exercise testing (CPX) is a form of exercise testing that measures ventilatory and gas exchange, heart rate, electrocardiogram, and blood pressures to provide detailed information on the cardiovascular, pulmonary, and muscular systems. This testing allows an accurate quantification of functional capacity/measure of exercise tolerance, diagnosis of cardiopulmonary disease, disease-progression monitoring or response to intervention, and the prescription of exercise and training. CPX directly measures inhaled and exhaled ventilator gases to determine the maximal oxygen uptake, which reflects the body's maximal use of oxygen and defines the limits of the cardiopulmonary system. CPX is the ideal modality to evaluate causes of exertional fatigue and dyspnea, especially in complex cases in which the etiology could be cardiac, pulmonary, or deconditioning. Exercise tolerance has become an important outcome measure in patients with chronic obstructive pulmonary disease and congestive heart failure, as well as other chronic diseases, and is a well recognized predictor of mortality. Older athletes or those with underlying medical conditions could benefit from exercise testing for risk stratification and clearance to participate, as well as to help set their training zones and determine their functional limitations.

TI Transfer of spatial reference frame using singlet states and classical communication SO QUANTUM INFORMATION PROCESSING LA English DT Article DE Quantum algorithm; Reference frame transfer; Quantum orientation ID LUMINOUS ETHER; INTERFEROMETER; INFORMATION; ROTATION AB A simple protocol is described for transferring spatial orientation from Alice to Bob (two spatially separated observers). The two observers are assumed to share quantum singlet states and classical communication. The protocol assumes that Alice and Bob have complete free will (measurement independence) and is based on maximizing the Shannon mutual information between Alice and Bob's measurement outcomes. Repeated use of this protocol for each spatial axis of Alice allows transfer of a complete three-dimensional reference frame, up to inversion of each of the axes. The technological complexity of this protocol is similar to that needed for BB84 quantum key distribution and hence is much simpler to implement than recently proposed schemes for transmission of reference frames. A second protocol based on a Bayesian formalism is also discussed. C1 [Bahder, Thomas B.] US Army, RDECOM, Aviat & Missile Res Dev & Engn Ctr, Charles M Bowden Lab, Redstone Arsenal, AL 35898 USA.

TI SENSITIVITY STUDY OF INPUT PARAMETERS FOR SEEPAGE FLOW SIMULATIONS USING PARALLEL COMPUTERS SO SCALABLE COMPUTING-PRACTICE AND EXPERIENCE LA English DT Article DE high performance computing; sensitivity analysis; finite element method; seepage flow modeling ID MODELS AB This paper describes a comprehensive sensitivity study that was performed using high performance parallel computers to understand the importance of input parameters to a transient partially saturated finite element seepage analysis for a levee with separate soil layers of sand, silty sand, and clay. Seepage flow in this paper refers to the type of flow of water that occurred through the failed levees in New Orleans, Louisiana, USA, as a result of Hurricane Katrina. The input parameters tested were saturated hydraulic conductivity, volumetric compressibility, residual moisture content, saturated moisture content, and two van Genuchten unsaturated flow parameters. The output data compiled to show the sensitivity of the input parameters were the simulation times (days) to achieve 25%, 50%, and 75% of the steady-state values of pore pressure at the toe of the levee beneath its blanket, flow rate through the landside flux section, and the level of saturation in the levee. The use of high performance parallel computers enabled the running of thousands of scenarios using different values for the input variables. A sensitivity investigation of this magnitude has not been previously performed. The results of this investigation indicated that the more sensitive soil parameters were the saturated hydraulic conductivity and the volumetric compressibility. The unsaturated van Genuchten parameters of the landside blanket had a larger than anticipated impact on the duration of time to achieve steady state. This practical example is an excellent success story for high performance computing in that running a given simulation for a couple of hours on thousands of processors in parallel replaced over a year's work using a PC.

Here, the oxygen plasma decouples the individual layers in MoS2 by perturbing the weak interlayer van der Waals forces without damaging the lattice structure. This decoupling causes a transition from an indirect to a direct band gap material, which causes a strong enhancement of the photoluminescence intensity. Furthermore, up to 80% circularly polarized photoluminescence is observed after plasma treatment of few layer MoS2 flakes, consistent with high spin polarization of the optically excited carriers. A strong degree of polarization continues up to room temperature, further indicating that the quality of the crystal does not suffer degradation due to the oxygen plasma exposure. Our results show that the oxygen plasma treatment not only engineers the van der Waals separation in these TMDC multilayers for enhanced PL quantum yields, but also produces high quality multilayer samples for strong circularly polarized emission, which offers the benefit of layer index as an additional degree of freedom, absent in monolayer MoS2.

In this paper, photonic crystals fabricated in thick tantalum (Ta) coatings, sputtered onto a metallic substrate, were investigated as a potential replacement for photonic crystals fabricated in bulk refractory metal substrates in TPV applications. A 2-D photonic crystal was fabricated in a 30-mu m thick Ta sputtered coating using standard semiconductor processes as a proof-of-concept for a selective emitter/solar absorber. The reflectance of the fabricated photonic crystal coating was characterized before and after 1 h anneals at 700, 900, and 1100. degrees C, and after a 24 h anneal at 900. degrees C. To protect its surface during the anneals, a thin conformal hafnia (HfO2) layer was deposited by atomic layer deposition on the photonic crystal. The photonic crystal showed high spectral selectivity in good agreement with numerical simulations and sustained the anneals with minimal structural degradation or change in its optical properties. This study presents a promising alternative to bulk substrates as a relatively low-cost and easily integrated platform for nanostructured devices in high-temperature energy conversion systems.

TI Improved Neural Signal Classification in a Rapid Serial Visual Presentation Task Using Active Learning SO IEEE TRANSACTIONS ON NEURAL SYSTEMS AND REHABILITATION ENGINEERING LA English DT Article DE Active learning; brain-computer interface; electroencephalography; rapid-serial visual presentation ID COUPLED COMPUTER VISION; FALSE DISCOVERY RATE; TARGET DETECTION; PERFORMANCE; RESPONSES; SEARCH; TRIAGE AB The application space for brain-computer interface (BCI) technologies is rapidly expanding with improvements in technology. However, most real-time BCIs require extensive individualized calibration prior to use, and systems often have to be recalibrated to account for changes in the neural signals due to a variety of factors including changes in human state, the surrounding environment, and task conditions. Novel approaches to reduce calibration time or effort will dramatically improve the usability of BCI systems. Active Learning (AL) is an iterative semi-supervised learning technique for learning in situations in which data may be abundant, but labels for the data are difficult or expensive to obtain. In this paper, we apply AL to a simulated BCI system for target identification using data from a rapid serial visual presentation (RSVP) paradigm to minimize the amount of training samples needed to initially calibrate a neural classifier. Our results show AL can produce similar overall classification accuracy with significantly less labeled data (in some cases less than 20%) when compared to alternative calibration approaches. In fact, AL classification performance matches performance of 10-fold cross-validation (CV) in over 70% of subjects when training with less than 50% of the data. To our knowledge, this is the first work to demonstrate the use of AL for offline electroencephalography (EEG) calibration in a simulated BCI paradigm. While AL itself is not often amenable for use in real-time systems, this work opens the door to alternative AL-like systems that are more amenable for BCI applications and thus enables future efforts for developing highly adaptive BCI systems.

TI Osteoid Osteoma of the Femoral Neck in Athletes: Two Case Reports Differentiating From Femoral Neck Stress Injuries SO SPORTS HEALTH-A MULTIDISCIPLINARY APPROACH LA English DT Article DE osteoid osteoma; femoral neck stress fracture; athletes; bone tumor ID LOWER-EXTREMITY; BONE-SCINTIGRAPHY; IMAGING FINDINGS; FRACTURES; RECRUITS; CT AB The diagnosis of an intra-articular osteoid osteoma can be a challenging and lengthy process, with reports of delayed diagnosis of greater than 2 years. In the young, athletic patient with an atraumatic onset of groin pain, an overuse injury or muscle strain is the most likely etiology. However, an overuse injury of femoral neck stress fracture must be identified because of the potentially disastrous outcome of fracture completion. The similar clinical presentation of a femoral neck stress fracture and intra-articular osteoid osteoma of the femoral neck can further delay the diagnosis of the osteoid osteoma. In a patient with these differential diagnoses that do not improve with a period of nonweightbearing activity, a more intensive workup must ensue. The purpose of this case report is to describe the initial presentations, subsequent follow-up, and imaging findings leading to the diagnosis of osteoid osteoma as well as to differentiate an osteoid osteoma from femoral neck stress injuries.

Filoviruses require processing by host cell-derived cysteine cathepsins for productive infection. Here we report the generation of a focused library of cysteine cathepsin inhibitors and subsequent screening to identify compounds with potent activity against viral entry and replication. Our top compounds show highly potent and broad-spectrum activity against cysteine cathepsins and were able to effectively block entry of Ebola and Marburg viruses. These agents are promising leads for development as antifilovirus therapeutics.

Are Some Kinases Better than Others for Inhibitor Repurposing? SO ACS INFECTIOUS DISEASES LA English DT Article DE preferred lead repurposing; Trypanosoma brucei; Trypanosoma cruzi; Leishmania major; Plasmodium falciparum; Published Kinase Inhibitor Set ID TRYPANOSOMA-BRUCEI; DRUG DISCOVERY; COMPOUND; POTENT AB A kinase-targeting cell-based high-throughput screen (HTS) against Trypanosoma brucei was recently reported, and this screening set included the Published Kinase Inhibitor Set (PKIS). From the PKIS was identified 53 compounds with pEC(50) >= 6. Utilizing the published data available for the PKIS, a statistical analysis of these active antiparasitic compounds was performed, allowing identification of a set of human kinases having inhibitors that show a high likelihood for blocking T. brucei cellular proliferation in vitro. This observation was confirmed by testing other established inhibitors of these human kinases and by mining past screening campaigns at GlaxoSmithKline. Overall, although the parasite targets of action are not known, inhibitors of this set of human kinases displayed an enhanced hit rate relative to a random kinase-targeting HTS campaign, suggesting that repurposing efforts should focus primarily on inhibitors of these specific human kinases. We therefore term this statistical analysis-driven approach "preferred lead repurposing".

Extensive tailoring to 12 of the 14 amino acid residues in the mature natural product endows PZN with not only a rigid, polyheterocyclic structure, but also antibacterial activity. Here we report the remarkably discriminatory activity of PZN toward Bacillus anthracis, which rivals a previously described gamma (gamma) phage lysis assay in distinguishing B. anthracis from other members of the Bacillus cereus group. We evaluate the underlying cause of this selective activity by measuring the RNA expression profile of PZN-treated B. anthracis, which revealed significant up-regulation of genes within the cell envelope stress response. PZN depolarizes the B. anthracis membrane like other cell envelope-acting compounds but uniquely localizes to distinct foci within the envelope. Selection and whole-genome sequencing of PZN-resistant mutants of B. anthracis implicate a relationship between the action of PZN and cardiolipin (CL) within the membrane. Exogenous CL increases the potency of PZN in wild type B. anthracis and promotes the incorporation of fluorescently tagged PZN in the cell envelope. We propose that PZN localizes to and exacerbates structurally compromised regions of the bacterial membrane, which ultimately results in cell lysis.

However, due to the paucity of cases, this has been difficult to study. Using a population-based national database, patient demographics and survival trends were analyzed to further elucidate the management of this malignancy. Methods: The SEER database was queried for patients diagnosed with ceruminous adenocarcinoma between 1973 and 2010. Results: Twenty-two patients were identified in the database. The average age of diagnosis was between 60 and 64 years. All of the patients underwent surgical resection of the primary malignancy. Eight patients (36%) also had postoperative radiation. Conclusions: Ceruminous adenocarcinoma is uncommon but may not have as poor a prognosis as previously thought. Surgical resection alone appears to be a reasonable treatment option. Larger prospective studies are needed, but database analysis like this may provide clarity on the management of uncommon diseases. Published by Elsevier Inc.

TI Reverse posterior interosseous flap for defects of the dorsal ulnar wrist using previously burned and recently grafted skin SO BURNS LA English DT Article DE Hand burn; Posterior interosseous artery flap ID LOCAL FASCIOCUTANEOUS FLAPS; RECONSTRUCTION; HAND AB Background: In the severely burned patient, coverage of exposed bone in the dorsal ulnar wrist can be a difficult problem. This is especially challenging in patients with a high percentage total body surface area (TBSA) where donor flaps can be scarce. The use of previously burned and/or recently grafted skin as flaps is an option. It has been postulated that use of previously burned skin can result in higher rates of local or distant flap failures. The reverse posterior interosseous flap (PIF) is an axial flap, based on the retrograde posterior interosseous artery, to provide coverage of the hand. Here we describe utilization of the PIF, using previously burned and/or recently grafted skin for coverage of dorsal ulnar wrist defects. Methods: This is a case series of three patients, with extensive burns (range 35-83% TBSA), where defects of the dorsal ulnar wrist necessitated coverage. Each patient underwent PIF(s) utilizing previously burned and/or grafted skin, all within three months after their initial burn event. Results: Case 1: 28 year old male who suffered 35% TBSA via blast mechanism developed a chronic open wound over the dorsal ulnar wrist with exposed tendon. The patient successfully underwent a left PIF using previously grafted skin. Case 2: 23 year old male with 83% TBSA. Bilateral ulnar styloids were exposed. PIFs were performed bilaterally, using previously burned and recently grafted skin. Coverage was successful but received leech therapy post-operatively for venous congestion. Case 3: 37 year old male with 52% TBSA, with the most severe burns isolated to his bilateral upper extremities; the ulnar head was exposed. The posterior interroseous artery was explored and PIF was attempted, but there was no retrograde flow in the distal artery due to a deeper injury than previously recognized. The patient ultimately underwent a pedicled abdominal flap for coverage. Conclusions: Defects of the distal ulnar wrist after deep and extensive burns can be problematic. Use of the reverse PIF using previously burned skin, even those that has just been recently grafted is a viable option for this difficult patient population. However, it may not be possible in all patients. Vigilance and early intervention for post-operative venous congestion are important. (C) 2015 Elsevier Ltd and ISBI. All rights reserved.

TI A nationwide assessment comparing nonelective open with minimally invasive complex colorectal procedures SO COLORECTAL DISEASE LA English DT Article DE Nonelective; emergent; colorectal surgery; laparoscopy ID RISK-ADJUSTED ANALYSIS; OPEN COLECTOMY; LAPAROSCOPIC COLECTOMY; SURGICAL OUTCOMES; COLON-CANCER; ARTHROPLASTY; MANAGEMENT; MORTALITY; COLITIS; DISEASE AB AimThe use of minimally invasive colorectal surgery has increased greatly for both benign and malignant disease. Studies evaluating complex procedures have been largely limited to elective indications. We aimed to compare the outcome of a laparoscopic with an open transverse (TC) and total abdominal colectomy (TAC) in the nonelective setting. MethodComparative analysis was made using the Nationwide Inpatient Sample (2008-11) of patients undergoing a nonelective TC or TAC identified by ICD-9-CM procedure codes. The risk-adjusted 30-day outcome was assessed using regression modelling accounting for patient characteristics, comorbidity and surgical procedure. ResultsWe identified 7261 admissions including 818 laparoscopic and 6443 open procedures. The mean age of the population was 6517years and patients in the laparoscopic group were younger (56 +/- 20 vs 66 +/- 17years; P<0.05). The rate of a single complication was lower in the laparoscopic group (26% vs 38%; P<0.01), but this did not remain significant following a logistic regression analysis. Mortality was significantly lower in the laparoscopic group (3.1% vs 17%; P<0.01) and this remained true after adjusting for covariates (OR=0.62; P<0.05). Laparoscopic cases were associated with a shorter median length of stay (10 vs 13days; P<0.01) and hospital charge ($75758 vs $98833; P<0.01). ConclusionA nonelective laparoscopic TC or TAC is associated with an equivalent complication rate and lower mortality compared with an open operation. The results should encourage surgeons with the appropriate skills to consider a laparoscopic approach for nonelective pathology requiring a complex colectomy. C1 [Schlussel, A.

Meanwhile, nonsteroidal anti-inflammatory medications are frequently associated with gastrointestinal side effects and acetaminophen liver toxicity. A trained physician can rapidly use certain acupuncture techniques in an austere environment with potentially fewer side effects. Current medical literature notes low to moderate quality evidence for the use of acupuncture in lower back pain and osteoarthritis of the knee. There is emerging evidence for the use of acupuncture in traumatic brain injury. The U.S. military uses acupuncture in deployed settings to treat battlefield injuries with promising results. This article reviews the military's current use of acupuncture to treat injuries in a deployed setting and how this may translate to the care of a sports injury in an austere environment.

With surfing at the core, a multitude of activities have evolved that attempt to harness the power of ocean waves. The unique qualities of each wave-riding sport, in combination with the environmental factors of the ocean, define the risk for potential injuries. As wave-riding sports have become more advanced, athletes continue to push physical barriers. Taller waves are attempted while incorporating aerial maneuvers, all without protective equipment.

TI Erosional Impacts of Modified Inlets, Beach Encroachment, and Beach Nourishment on the East Coast of Florida SO JOURNAL OF COASTAL RESEARCH LA English DT Article DE Beach; erosion; inlets; beach nourishment; shoreline change AB Most of the 21 inlets along the 588 km of sandy shoreline on the Florida east coast have been modified, primarily to improve navigation efficiency and safety. These modifications have usually caused significant downdrift shoreline erosion. Shoreline change data for the Florida east coast during the period from about 1869 to 1971, which was before widespread beach nourishment, are analyzed. Modified inlets during this period impacted about 25% of the shoreline and conservatively caused about 70% of the shoreline area recession and about 75-85% if counties are excluded that did not have modified inlets that caused net downdrift recession. During this same period of about 100 years, the remaining 75% of the shoreline advanced on average 46 m seaward. However, before Florida began regulating coastal construction, development often encroached on accreting shorelines, effectively masking much of the accretion. From about 1971 to 2007, a period of widespread beach nourishment, only about half of the nourishment sand was placed on eroding shorelines. About half was placed on shorelines that accreted or were stable from about 1869 to 1971 but where encroachment by development made the nourishment necessary. Over half of the recession caused by modified inlets still exists. The criteria used by the Florida Department of Environmental Protection to designate the erosional state of Florida east coast beaches was found to be problematic, since it currently designates 65% of this shoreline as eroding when only 20% eroded during the period of widespread beach nourishment from about 1971 to 2007.

TI Clinical data, clinicopathologic findings and outcome in dogs with amegakaryocytic thrombocytopenia and primary immune-mediated thrombocytopenia SO JOURNAL OF SMALL ANIMAL PRACTICE LA English DT Article ID BONE-MARROW; PURPURA AB OBJECTIVESThe aim of this study was to identify distinguishing characteristics between dogs diagnosed with amegakaryocytic thrombocytopenia and those diagnosed with presumed primary peripheral immune-mediated thrombocytopenia. Presenting clinical and clinicopathologic data and outcomes were compared between the two groups. METHODSRetrospective study performed on seven client-owned dogs diagnosed with amegakaryocytic thrombocytopenia and 34 client-owned dogs with primary peripheral immune-mediated thrombocytopenia. RESULTSAll dogs in the amegakaryocytic thrombocytopenia group were anaemic on presentation with a median haematocrit of 23% (range 94 to 36), while the primary peripheral immune-mediated thrombocytopoenia group had a median presenting haematocrit of 35% (range 10 to 53). Dogs with amegakaryocytic thrombocytopenia had a median of five (range 4 to 7) clinical signs of bleeding compared to a median of three (range 0 to 6) in the primary peripheral immune-mediated thrombocytopenia group with 86% (6 of 7) of amegakaryocytic thrombocytopenia dogs requiring a blood transfusion compared to 41% (14 of 34) of primary peripheral immune-mediated thrombocytopenia dogs. Six of the seven amegakaryocytic thrombocytopenia dogs did not survive to discharge, while only five of the 34 primary peripheral immune-mediated thrombocytopenia dogs did not survive to discharge. CLINICAL SIGNIFICANCEThe clinical presentation of dogs with amegakaryocytic thrombocytopenia and primary peripheral immune-mediated thrombocytopenia is similar, but dogs with amegakaryocytic thrombocytopenia had a more severe clinical course compared to primary peripheral immune-mediated thrombocytopenia dogs. The prognosis for dogs with amegakaryocytic thrombocytopenia is poor. C1 [Cooper, S. A.; Huang, A. A.; Scott-Moncrieff, J. C.] Purdue Univ, Coll Vet Med, Dept Vet Clin Sci, W Lafayette, IN 47907 USA.

TI Rhabdomyolysis among critically ill combat casualties: Associations with acute kidney injury and mortality SO JOURNAL OF TRAUMA AND ACUTE CARE SURGERY LA English DT Article DE Rhabdomyolysis; acute kidney injury; trauma; war; mortality ID ACUTE-RENAL-FAILURE; TRAUMA PATIENTS; SERUM CREATININE; MARMARA EARTHQUAKE; RIFLE CRITERIA; CRUSH SYNDROME; RISK-FACTORS; CARE; MYOGLOBIN; SEVERITY AB BACKGROUND Rhabdomyolysis has been associated with poor outcomes in patients with traumatic injury, especially in the setting of acute kidney injury (AKI). However, rhabdomyolysis has not been systematically examined in a large cohort of combat casualties injured in the wars in Iraq and Afghanistan. METHODS We conducted a retrospective study of casualties injured during combat operations in Iraq and Afghanistan who were initially admitted to the intensive care unit from February 1, 2002, to February 1, 2011. Information on age, sex, Abbreviated Injury Scale (AIS) score, Injury Severity Score (ISS), mechanism of injury, shock index, creatine kinase, and serum creatinine were collected. These variables were examined via multivariate logistic and Cox regression analyses to determine factors independently associated with rhabdomyolysis, AKI, and death. RESULTS Of 6,011 admissions identified, a total of 2,109 patients met inclusion criteria and were included for analysis. Rhabdomyolysis, defined as creatine kinase greater than 5,000 U/L, was present in 656 subjects (31.1%). Risk factors for rhabdomyolysis identified on multivariable analysis included injuries to the abdomen and extremities, increased ISS, male sex, explosive mechanism of injury, and shock index greater than 0.9. After adjustment, patients with rhabdomyolysis had a greater than twofold increase in the odds of AKI. In the analysis for mortality, rhabdomyolysis was significantly associated with death until AKI was added, at which point it lost statistical significance. CONCLUSION We found that rhabdomyolysis is associated with the development of AKI in combat casualties. While rhabdomyolysis was strongly associated with mortality on the univariate model and in conjunction with both ISS and age, it was not associated with mortality after the inclusion of AKI. This suggests that the effect of rhabdomyolysis on mortality may be mediated by AKI. LEVEL OF EVIDENCE Prognostic and epidemiologic study, level III.

Tailoring graphene's properties toward a selected application requires precise control of the atomic layer growth process, transfer, and postprocessing procedures. To date, the mechanical properties of graphene are largely controlled through postprocess defect engineering techniques. In this work, we demonstrate the role of varied catalytic surface morphologies on the tailorability of subsequent graphene film quality and breaking strength, providing a mechanism to tailor the physical, electrical, and mechanical properties at the growth stage. A new surface planarization methodology that results in over a 99% reduction in Cu surface roughness allows for smoothness parameters beyond that reported to date in literature and clearly demonstrates the role of Cu smoothness toward a decrease in the formation of bilayer graphene defects, altered domain sizes, monolayer graphene sheet resistance values down to 120 Omega/rectangle and a 78% improvement in breaking strength. The combined electrical and mechanical enhancements achieved through this methodology allows for the direct growth of application quality flexible transparent conductive films with monolayer graphene.

TI Process, Policy, and Implementation of Pool-Wide Drawdowns on the Upper Mississippi River: A Promising Approach for Ecological Restoration of Large Impounded Rivers SO RIVER RESEARCH AND APPLICATIONS LA English DT Article DE drawdown; navigation pool; restoration; upper Mississippi River; water level management ID WATER-LEVEL MANAGEMENT; VEGETATION; EXPOSURE AB The Upper Mississippi River (UMR) has been developed and subsequently managed for commercial navigation by the U.S. Army Corps of Engineers (USACE). The navigation pools created by a series of lock and dams initially provided a complex of aquatic habitats that supported a variety of fish and wildlife. However, biological productivity declined as the pools aged. The River Resources Forum, an advisory body to the St. Paul District of the USACE, established a multiagency Water Level Management Task Force (WLMTF) to evaluate the potential of water level management to improve ecological function and restore the distribution and abundance of fish and wildlife habitat. The WLMTF identified several water level management options and concluded that summer growing season drawdowns at the pool scale offered the greatest potential to provide habitat benefits over a large area. Here we summarize the process followed to plan and implement pool-wide drawdowns on the UMR, including involvement of stakeholders in decision making, addressing requirements to modify reservoir operating plans, development and evaluation of drawdown alternatives, pool selection, establishment of a monitoring plan, interagency coordination, and a public information campaign. Three pool-wide drawdowns were implemented within the St. Paul District and deemed successful in providing ecological benefits without adversely affecting commercial navigation and recreational use of the pools. Insights are provided based on more than 17years of experience in planning and implementing drawdowns on the UMR. Copyright (c) 2015 John Wiley & Sons, Ltd. C1 [Kenow, K. P.; Newton, T.

Formulations employing KNO3 as the oxidizer, MgB2 as the fuel, and various binders and additives were investigated. Upon combustion, the compositions were found to generate the photochemically active BO2 radical, which emits green light. Fixing the MgB2 content at 21 wt % gave the closest dominant wavelength (561.4 nm) to that desired for green illuminants and a spectral purity of 33%. The addition of burning rate modifiers to this system was found to inhibit the formation of the BO2 radical. Exchanging the KNO3 oxidizer for NH4ClO4 increased the spectral purity to 45%. Correlations between the results of thermodynamic modeling and the experimental data are also reported. C1 [Brusnahan, Jason S.] Def Sci & Technol Grp, Edinburgh, SA 5111, Australia.

Recent Advances: Our knowledge of the molecular pathways involved in burn wounds has increased dramatically, and technological advances now allow large-scale genomic studies, providing a global view of wound healing processes. Critical Issues: Translating findings from a large number of in vitro and preclinical animal studies into clinical practice represents a gap in our understanding, and the failures of a number of clinical trials suggest that targeting single pathways or cytokines may not be the best approach. Significant opportunities for improvement exist. Future Directions: Study of the underlying molecular influences of burn wound healing progression will undoubtedly continue as an active research focus. Increasing our knowledge of these processes will identify additional therapeutic targets, supporting informed clinical studies that translate into clinical relevance and practice.

TI Noninvasive assessment of extracellular and intracellular dehydration in healthy humans using the resistance-reactance-score graph method SO AMERICAN JOURNAL OF CLINICAL NUTRITION LA English DT Article DE volume depletion; hydration assessment; BIVA; hypohydration; hypovolemia ID BODY-WATER COMPARTMENTS; BIOELECTRICAL-IMPEDANCE; BIOIMPEDANCE SPECTROSCOPY; DIAGNOSTIC-ACCURACY; MARKERS; STRESS; PLASMA; VOLUME; BLOOD; MEN AB Background: Few dehydration assessment measures provide accurate information; most are based on reference change values and very few are diagnostically accurate from a single observation or measure. Bioelectrical impedance may lack the precision to detect common forms of dehydration in healthy individuals. Limitations in bioimpedance may be addressed by a unique resistance reactance (RXc)-score graph method, which transforms vector components into z scores for use with any impedance analyzer in any population. Objective: We tested whether the RXc-score graph method provides accurate single or serial assessments of dehydration when compared with gold-standard measures of total body water by using stable isotope dilution (deuterium oxide) combined with body weight changes. Design: We retrospectively analyzed data from a previous study in which 9 healthy young men participated in 3 trials: euhydration (EUH), extracellular dehydration (ED; via a diuretic), and intracellular dehydration (ID; via exercise in the heat). Results: Participants lost 4-5% of their body weight during the dehydration trials; volume loss was similar between trials (ID compared with ED group: 3.5 +/- 0.8 compared with 3.0 +/- 0.6 L; P > 0.05). Despite significant losses of body water, most RXc vector scores for ED and ID groups were classified as "normal" (within the 75% population tolerance ellipse). However, directional displacement of vectors was consistent with loss of volume in both ED and ID conditions compared with the EUH condition and tended to be longer in ED than in ID conditions (P = 0.054). Conclusions: We conclude that, whereas individual RXc-score graph values do not provide accurate detection of dehydration from single measurements, directional changes in vector values from serial measurements are consistent with fluid loss for both ED and ID conditions. The RXc-score graph method may therefore alert clinicians to changes in hydration state, which may bolster the interpretation of other recognized change measures of hydration.

TI The Effects of an Injury Prevention Program on Landing Biomechanics Over Time SO AMERICAN JOURNAL OF SPORTS MEDICINE LA English DT Article DE biomechanics; neuromuscular training; military ID RANDOMIZED-CONTROLLED-TRIAL; CRUCIATE LIGAMENT INJURY; LOWER-EXTREMITY INJURY; ERROR SCORING SYSTEM; JUMP-ACL; SOCCER PLAYERS; FEMALE SOCCER; BALANCE; DESIGN; TOOL AB Background: Knowledge is limited regarding how long improvements in biomechanics remain after completion of a lower extremity injury prevention program. Purpose: To evaluate the effects of an injury prevention program on movement technique and peak vertical ground-reaction forces (VGRF) over time compared with a standard warm-up (SWU) program. Study Design: Controlled laboratory study. Methods: A total of 1104 incoming freshmen (age range, 17-22 years) at a military academy in the United States volunteered to participate. Participants were cluster-randomized by military company to either the Dynamic Integrated Movement Enhancement (DIME) injury prevention program or SWU. A random subsample of participants completed a standardized jump-landing task at each time point: immediately before the intervention (PRE), immediately after (POST), and 2 (POST2M), 4 (POST4M), 6 (POST6M), and 8 months (POST8M) after the intervention. VGRF data collected during the jump-landing task were normalized to body weight (%BW). The Landing Error Scoring System (LESS) was used to evaluate movement technique during the jump landing. The change scores () for each variable (LESS, VGRF) between the group's average value at PRE and each time point were calculated. Separate univariate analyses of variance were performed to evaluate group differences. Results: The results showed a greater decrease in mean (SD) VGRF in the DIME group compared with the SWU group at all retention time points: POST2M (SWU [(%BW)], -0.13 0.82; DIME, -0.62 +/- 0.91; P = .001), POST4M (SWU, -0.15 +/- 0.98; DIME,-0.46 +/- 0.64; P = .04), POST6M (SWU, -0.04 +/- 0.96; DIME, -0.53 +/- 0.83; P = .004), and POST8M (SWU, 0.38 +/- 0.95; DIME, -0.11 +/- 0.98; P = .003), but there was not a significant improvement in the DIME group between PRE and POST8M ((%BW), -0.11 +/- 0.98). No group differences in LESS were observed. Conclusion: The study findings demonstrated that an injury prevention program performed as a warm-up can reduce vertical ground-reaction forces compared with a standard warm-up but a maintenance program is likely necessary in order for continued benefit. Clinical Relevance: Injury prevention programs may need to be performed constantly, or at least every sport season, in order for participants to maintain the protective effects against injury.

Over the past decade, our team has investigated interindividual variability in human blood pressure regulation. What advances does it highlight? In men, we have found a tight relationship between indices of sympathetic activity and vascular resistance across the age span. This relationship is absent in young women but seen in postmenopausal women. These sex and age differences in vascular resistance are largely a result of changes in the balance of vasodilating and vasoconstricting adrenergic receptor tone. When these changes are considered along with cardiac output, a coherent picture is beginning to emerge of why blood pressure rises more with age in women than men. Arterial pressure is a key regulated variable in the cardiovascular system with important health implications. Over the last 12years, we have used physiological measurements, including muscle sympathetic nerve activity (MSNA), to explore the balance among mean arterial blood pressure, cardiac output and total peripheral resistance (TPR) in normotensive humans. We have shown that these determinants of blood pressure can vary widely in different subjects and how they vary depends on sex and age. In young men, there is a direct relationship between MSNA and TPR but no relationship with blood pressure. This is because cardiac output is proportionally lower in those with high MSNA and TPR. In contrast, in young women there is no relationship between MSNA and TPR (or cardiac output); this is because -adrenergic vasodilator mechanisms offset -adrenergic vasoconstriction. Thus, blood pressure is unrelated to MSNA in young women. In older women, -adrenergic vasodilator mechanisms are diminished, and a direct relationship between MSNA and TPR is seen. In older men, the relationships among these variables are less clear cut, perhaps owing to age-related alterations in endothelial function. With ageing, the relationship between MSNA and blood pressure becomes positive, more so in women than in men. The finding that the physiological control of blood pressure is so different in men and women and that it varies with age suggests that future studies of mechanisms of hypertension will reveal corresponding differences among groups.

TI Clinical Pharmacists as Educators in Family Medicine Residency Programs: A CERA Study of Program Directors SO FAMILY MEDICINE LA English DT Article ID BOARD CERTIFICATION; ECONOMIC OUTCOMES; TRAINING-PROGRAM; SERVICES; MANAGEMENT; CARE; RECOMMENDATIONS; PRACTITIONERS; SPECIALISTS; EXPERIENCE AB BACKGROUND AND OBJECTIVES: The clinical pharmacist's role within family medicine residency programs (FMRPs) is well established. However, there is limited information regarding perceptions of program directors (PDs) about clinical pharmacy educators. The study objectives were (1) to estimate the prevalence of clinical pharmacists within FMRPs and (2) to determine barriers and motivations for incorporation of clinical pharmacists as educators. METHODS: The Council of Academic Family Medicine Educational Research Alliance (CERA) distributed an electronic survey to PDs. Questions addressed formalized pharmacotherapy education, clinical pharmacists in educator roles, and barriers and benefits of clinical pharmacists in FMRPs. RESULTS: The overall response rate was 50% (224/451). Seventy-six percent (170/224) of the responding PDs reported that clinical pharmacists provide pharmacotherapy education in their FMRPs, and 57% (97/170) consider clinical pharmacists as faculty members. In programs with clinical pharmacists, 72% (83/116) of PDs reported having a systematic approach for teaching pharmacotherapy versus 22% (21/95) in programs without. In programs without clinical pharmacists, the top barrier to incorporation was limited ability to bill for clinical services 48% (43/89) versus 29% (32/112) in programs with clinical pharmacists. In both programs with and without clinical pharmacists, the top benefit of having clinical pharmacists was providing a collaborative approach to pharmacotherapy education for residents (35% and 36%, respectively). CONCLUSIONS: Less than half of FMRPs incorporate clinical pharmacists as faculty members. Despite providing collaborative approaches to pharmacotherapy education, their limited ability to bill for services is a major barrier.

Astronauts with neuro-ophthalmic findings, which were not present at the start of a space flight mission and only seen on return from long-duration space missions to the International Space Station, will be discussed.Results:After 6 months of space flight, 7 astronauts had ophthalmic findings consisting of optic disc edema in 5, globe flattening in 5, choroidal folds in 5, cotton-wool spots in 3, nerve fiber layer thickening detected by optical coherence tomography in 6, and decreased near vision in 6. Five of 7 astronauts with near vision complaints had a hyperopic shift +0.50 diopters (D) between pre-/post-mission spherical equivalent refraction in 1 or both eyes (range, +0.50 to +1.75 D). These 5 astronauts showed globe flattening on magnetic resonance imaging. A total of 6 lumbar punctures have been performed to date (4 in the originally described cohort) and documented opening pressures of 18, 22, 21, 21.5, 28, and 28.5 cm H2O. These were performed at 8, 66, 19, 7, 12, and 57 days after mission, respectively. The 300 postflight questionnaires documented that approximately 29% and 60% of astronauts on short-duration and long-duration missions, respectively, experienced a degradation in distant and near visual acuity. Some of these vision changes remain unresolved for years after flight. Several possible pathogenic mechanisms, as well as potential countermeasures and discussion of possible terrestrial implications, are described.Conclusions:We previously hypothesized that the optic nerve and ocular changes that we described in astronauts may be the result of orbital and cranial cephalad fluid shifts brought about by prolonged microgravity exposure. The findings we reported previously and continue to see in astronauts may represent parts of a spectrum of ocular and cerebral responses to extended microgravity exposure. Future investigations hopefully will lead to countermeasures that can be used to eliminate or lessen the magnitude of these potentially harmful findings before long-duration space flight including the possibility of a manned mission to Mars.

TI An Impedance-Based Model for the Assessment of Cardiopulmonary Function in Rabbits SO JOURNAL OF THE AMERICAN ASSOCIATION FOR LABORATORY ANIMAL SCIENCE LA English DT Article ID PNEUMOGRAPH AB Improving the quality of physiologic data collected from research animals is most easily accomplished by collecting as much information as possible from a single subject, thereby reducing animal use and error associated with satellite groups. We investigated the feasibility of using a large-animal implantable telemetry device in New Zealand white rabbits (n = 6). The first task was to develop an implantation technique that yielded calibrated tidal volume (Vt) measurements that were within 10% of those obtained simultaneously from a pneumotachograph, a low-noise electrocardiogram, and stable blood pressure. The second task was to challenge implanted rabbits with the respiratory stimulant doxapram to assess linearity of the calibration across a range of Vt. Of the 3 electrode placements attempted, only one resulted in calibrations consistently below 10% error. Optimal electrode placement resulted in calibrated Vt measurements within 1.7% +/- 0.3% of those obtained from a pneumotachograph during normal tidal breathing, 7.3% +/- 0.7% of those after saline injection, and 6.0% +/- 0.5% of those after doxapram injection. The Vt range was 9 to 15 mL for normal tidal breathing and saline injection and 25 to 30 mL after doxapram injection. Increases in mean arterial pressure of 25.0 +/- 6.82 mm Hg and decreases in heart rate of 56.3 +/- 6.82 bpm were associated with doxapram injection only. Our findings represent the first time that multiple cardiopulmonary endpoints have been assessed by telemetry in conscious, restrained rabbits. Whether animal position affects calibration accuracy warrants investigation. C1 [Horsmon, Michael S.; Kristovich, Robert L.] US Army, Edgewood Chem Biol Ctr, Gunpowder, MD USA.

Recently we derived an approximate formula for predicting the frequency shift between near-and far-field intensity peaks in the case of a dielectric sphere. In this work we demonstrate that almost an identical formula can be used to predict the resonance shift of a dielectric cylinder and a perfectly conducting cylinder. We find the redshift of the resonance peak of the perfect electric conducting cylinder to be approximately 2 orders of magnitude greater than for the dielectric cylinder. The errors in our approximate analytic formula for predicting the redshift are approximately only twice as great. Furthermore, we apply the redshift formula to a silicon cylinder and discuss its magneto-dielectric properties, which may be of interest in design of metamaterials.

TI Nautical Depth for US Navigable Waterways: A Review SO JOURNAL OF WATERWAY PORT COASTAL AND OCEAN ENGINEERING LA English DT Review DE Dredging; Fluid mud; Channels; Ports; Harbors; Nautical depth; Bathymetric survey; Echo sounder ID FLUID MUD; NAVIGATION; AREAS; MANAGEMENT; ESTUARIES; LAKES; BAYS AB The present state of navigation engineering knowledge concerning nautical depth in ports and waterways with fluid mud is summarized to examine the potential for successful application of the nautical depth concept in U.S. navigable waterways. Nautical depth defines a safe and effective channel bottom criterion in areas where fluid mud confounds conventional acoustic (echo sounder) surveying methods. Fluid mud is a high-concentration suspension that typically behaves as a non-Newtonian fluid. It occurs in ports and channels on all U.S. coastlines and accounts for a significant portion of the United States' $1 billion dredging expense. Nautical depth has been adopted in multiple ports on three continents. Where nautical depth application is appropriate, it often reduces dredging frequency and dredged material volume and can provide water quality benefits. Multiple experiments and field experience have shown that vessels can safely transit areas with fluid mud below the keel. The United States' adoption of the nautical depth concept for select ports and waterways can be expected to reduce dredging frequency and volumes. It offers potential economic and environmental benefits but will require a consensus among federal, state, and local organizations with responsibilities for constructing, operating, maintaining, marking, and using navigable waterways.

Kimberley TI Postmortem Propofol Levels A Case of Residual Detection Long After Administration SO AMERICAN JOURNAL OF FORENSIC MEDICINE AND PATHOLOGY LA English DT Article DE propofol; residual; Diprivan; forensic pathology; postmortem; detection ID PHARMACOKINETICS; LETHAL; ABUSE; DEATH; PHARMACODYNAMICS; INTOXICATION; SEDATION AB Propofol has gained notoriety in recent years because of its involvement in high-profile deaths and has increasingly become a drug of misuse and abuse particularly by health care personnel with easy access to it. In addition, propofol has also been used for more nefarious purposes such as murder and suicide. These, coupled with the drug's routine use for both major and minor medical procedures, provide ample opportunities for it to be implicated as a cause of death or contributing factor. In such instances, forensic investigators may be faced with the task of not only detecting the presence of propofol on postmortem toxicology screening, but also determining if it was indeed responsible for the decedent's demise. While propofol has a high volume of distribution, it is thought to equilibrate and be eliminated rapidly and not show significant tissue accumulation. However, this article presents a case illustrating that propofol can accumulate in the tissues and may be found up to a week after administration. This capacity to accumulate implies that postmortem detection does not necessarily confirm administration near the time of death, and further investigation needs to be undertaken to determine the timeline of events in order to rule out other factors, such as recent medical interventions, before attributing the cause of death to the presence of the drug.

Methods: Six spontaneously breathing healthy ewes were connected to an extracorporeal circuit with blood flow 250 ml/min and gas flow 10 l/min. Sheep underwent two randomly ordered experimental sequences, each consisting of two 12-h alternating phases of ALCO(2)R and ECCO2R. During ALCO(2)R, lactic acid (1.5 mEq/min) was infused before the membrane lung. Caloric intake was not controlled, and animals were freely fed. VCO2ML, natural lung carbon dioxide extraction, total carbon dioxide production, and minute ventilation were recorded. Oxygen consumption and EE were calculated. Results: ALCO(2)R enhanced VCO2ML by 48% relative to ECCO2R (55.3 +/- 3.1 vs. 37.2 +/- 3.2 ml/min; P less than 0.001). During ALCO(2)R, minute ventilation and natural lung carbon dioxide extraction were not affected (7.88 +/- 2.00 vs. 7.51 +/- 1.89 l/min, P = 0.146; 167.9 +/- 41.6 vs. 159.6 +/- 51.8 ml/min, P = 0.063), whereas total carbon dioxide production, oxygen consumption, and EE rose by 12% each (223.53 +/- 42.68 vs. 196.64 +/- 50.92 ml/min, 215.3 +/- 96.9 vs. 189.1 +/- 89.0 ml/min, 67.5 +/- 24.0 vs. 60.3 +/- 20.1 kcal/h; P less than 0.001). Conclusions: ALCO(2)R was effective in enhancing VCO2ML. However, lactic acid caused a rise in EE that made ALCO(2)R no different from standard ECCO2R with respect to ventilation. The authors suggest coupling lactic acid-enhanced ALCO(2)R with active measures to control metabolism.

We derive expressions for the stress, velocity, and electric displacement in the target at all times after impact. A combined d'Alembert and Laplace transform method is used to derive new numerically based solutions for this class of transient wave propagation problems. A modified Dubner-Abate-Crump (DAC) algorithm is used to invert the analytical Laplace transform domain solutions to the time domain. Unlike many authors who neglect electromechanical coupling in the initially unstressed region ahead of the shock, we consider this effect, which gives rise to the development of a tensile stress wave within the piezoelectric target ahead of the shock. To solve the problem, we derive a new piezoelectric impact boundary condition and apply it to the problem of a finite quartz (Si) flyer impacting a lead zirconate titanate (PZT-4) target and find that the solutions obtained using the modified DAC algorithm compare well with those obtained using both a finite-difference time-domain method, and the commercial finite element code, COMSOL multiphysics.

Background: Increased information is often associated with an improvement of SA and decision-making performance in networked organizations. However, previous research suggests that increasing information without considering the task relevance and the presentation can impair performance. Method: We used a simulated C2 task across two experiments. Experiment 1 varied the information volume provided to individual participants and measured the speed and accuracy of decision making for task performance. Experiment 2 varied information volume and information reliability provided to two participants acting in different roles and assessed decision-making performance, SA, and trust between the paired participants. Results: In both experiments, increased task-relevant information volume did not improve task performance. In Experiment 2, increased task-relevant information volume reduced self-reported SA and trust, and incorrect source reliability information led to poorer task performance and SA. Conclusion: These results indicate that increasing the volume of information, even when it is accurate and task relevant, is not necessarily beneficial to decision-making performance. Moreover, it may even be detrimental to SA and trust among team members. Application: Given the high volume of available and shared information and the safety-critical and time-sensitive nature of many decisions, these results have implications for training and system design in C2 domains. To avoid decrements to SA, interpersonal trust, and decision-making performance, information presentation within C2 systems must reflect human cognitive processing limits and capabilities.

TI Risk of postoperative urinary tract infections following midurethral sling operations in women undergoing hysterectomy SO INTERNATIONAL UROGYNECOLOGY JOURNAL LA English DT Article; Proceedings Paper CT 40th Meeting of the International-Urogynecological-Association CY JUN 11, 2015 CL Nice, FRANCE SP Amer Urogynecol Soc DE Hysterectomy; Midurethral sling; Prolapse operations; TOT; TVT; Urinary tract infection ID RANDOMIZED-CONTROLLED-TRIAL; SURGERY; COMPLICATIONS; PROPHYLAXIS AB Introduction and hypothesis Urinary tract infections (UTIs) are the most common complication following hysterectomy and mid-urethral sling procedures (MUS). As a MUS is often placed at the time of hysterectomy, we sought to determine if the addition of an MUS procedure significantly increases the risk of UTI in the first 30 days following hysterectomy. Methods This retrospective cohort study utilizes the National Surgical Quality Improvement Program (NSQIP) data bank for the years 2006-2012. The database collects data on all enrolled patients preoperatively and in the first 30 days postoperatively.The database was searched using procedural codes for various types of hysterectomies and MUS procedures. We assessed the incidence of postoperative UTIs following hysterectomy (HYST) only, MUS only, and hysterectomy combined with MUS (HYST+MUS). Adjusted logistic regression analyses were performed to evaluate the effects of individual risk factors and models of interaction. Results The NSQIP cohort included 3,757 in the HYST+MUS group, 9,851 in the MUS-only group, and 57,398 in the HYST-only group. The rates of postoperative UTI, which was the most common postoperative morbidity, were 5.3, 3.4, and 2.5 % respectively. Multivariate logistic regression analysis showed a persistent significant increase in rates of UTI (p<0.001) between the MUS+HYST group and the HYST-only group. This significance was not maintained between the MUS-only group and the MUS+HYST group. Conclusions Data from the NSQIP databank indicate that performing an MUS in combination with hysterectomy nearly doubles the risk of postoperative UTI over a hysterectomy alone.

In this work, a novel segmentation technique is proposed, starting with octree decomposition to recursively divide the scene into octants or voxels, followed by a novel split and merge framework that uses graph theory and a series of connectivity analyses to intelligently merge components into larger connected components. The connectivity analysis, based on a combination of proximity, orientation, and curvature connectivity criteria, is designed for the segmentation of pipes, vessels, and walls from terrestrial LiDAR data of piping systems at industrial sites, such as oil refineries, chemical plants, and steel mills. The proposed segmentation method is exercised on two terrestrial LiDAR datasets of a steel mill and a chemical plant, demonstrating its ability to correctly reassemble and segregate features of interest.

Applications like motor drive require power MOSFETs to drive highly inductive loads which increase the switching power loss by extending the voltage and current crossover, a situation which gets exacerbated by the presence of parasitic inductance. A 2D model of a 1200 V 4H-SiC vertical DMOSFET half-cell was developed using a commercially available TCAD software package to investigate the electro-thermal switching characteristics using clamped inductive switching circuit for ON state drain current density values up to at an ambient lattice temperature of 300 K. Device physics-based models were included to account for carrier mobility, carrier generation and recombination, impact ionization and lattice heating. In order to analyze the areas of localized lattice heating, the lattice temperature distribution was monitored during simulation. The clamped inductive switching circuit simulations were performed with and without the addition of parasitic electrode inductance to observe the difference in switching energy loss.

This is particularly the case for atmospheric sciences, which have long relied on either simplistic analytical solutions or computationally expensive numerical models. The simpler solutions are inadequate for many problems, while the cost of numerical models makes their use impossible for many problems, most notably high-resolution climate downscaling applications spanning large areas, long time periods, and many global climate projections. Here the Intermediate Complexity Atmospheric Research model (ICAR) is presented to provide a new step along the modeling complexity continuum. ICAR leverages an analytical solution for high-resolution perturbations to wind velocities, in conjunction with numerical physics schemes, that is, advection and cloud microphysics, to simulate the atmosphere. The focus of the initial development of ICAR is for predictions of precipitation, and eventually temperature, humidity, and radiation at the land surface. Comparisons between ICAR and the Weather Research and Forecasting (WRF) Model for simulations over an idealized mountain are presented, as well as among ICAR, WRF, and the Parameter-Elevation Regressions on Independent Slopes Model (PRISM) observation-based product for a year-long simulation over the Colorado Rockies. In the ideal simulations, ICAR matches WRF precipitation predictions across a range of environmental conditions with a coefficient of determination r(2) of 0.92. In the Colorado Rockies, ICAR, WRF, and PRISM show very good agreement, with differences between ICAR and WRF comparable to the differences between WRF and PRISM in the cool season. For these simulations, WRF required 140-800 times more computational resources than ICAR.

It was found that the chemical shifts of both O-17 and Li-6 changed with the concentration of LiFSI, indicating the changes of solvation structures with concentration. For the quantum chemistry calculations, the coordinated cluster LiFSI(DME)(2) forms at first, and its relative ratio increases with increasing LiFSI concentration to 1 M. Then the solvation structure LiFSI(DME) become the dominant component. As a result, the coordination of forming contact ion pairs between Li+ and FSI- ion increases, but the association between Li+ and DME molecule decreases. Furthermore, at LiFSI concentration of 4 M the solvation structures associated with Li+(FSI-)(2)(DME), Li-2(+)(FSI-)(DME)(4) and (LiFSI)(2)(DME)(3) become the dominant components. For the molecular dynamics simulation, with increasing concentration, the association between DME and Li+ decreases, and the coordinated number of FSI- increases, which is in perfect accord with the DFT results.

However, the critical challenges for these materials come from the absence of Li source in them, and low power density and poor cycling stability. Herein, pre-lithiated FeF3 with extremely small size of Fe and LiF nanoparticles (both similar to 6 nm) homogeneously embedded in the carbon matrix were synthesized using a facile and scalable in situ strategy. Benefited from the ultra-small Fe and LiF nanoparticles, uniform distribution, and intimate contact between the active species and the carbon matrix, the particle-to-particle interfacial resistance and diffusion length for Li and F are dramatically reduced. As a result, a high specific capacity of over 400 mA h g(-1) with a discharge energy density of similar to 700 W h kg(-1) and favorable cycling performance are achieved, making such composite a promising high-capacity cathode for LIBs. Furthermore, the built-in Li source in this composite renders it a drop-in replacement for cathode materials used in the current LIB configurations, thus paving the way for the practical applications in the text generation of high energy density LIBs.

However, in the past two decades, drug-induced sleep endoscopy (DISE) has been used as a method of tridimensional evaluation of the upper airway during pharmacologically induced sleep. This study aimed to systematically review the evidence regarding the usefulness of DISE compared with that of traditional awake examination for surgical decision making in patients with obstructive sleep apnea (OSA). Data SourcesScopus, PubMed, and Cochrane Library databases were searched. Review MethodsOnly studies with a primary objective of evaluating the usefulness of DISE for surgical decision making in patients with OSA were selected. The included studies directly compared awake examination data with DISE outcome data in terms of possible influences on surgical decision making and operation success. ResultsA total of eight studies with 535 patients were included in this review. Overall, the surgical treatment changed after DISE in 50.24% (standard deviation 8.4) cases. These changes were more frequently associated with structures contributing to hypopharyngeal or laryngeal obstruction. However, these differences do not automatically indicate a higher success rate. ConclusionThis review emphasized the direct impact of DISE compared with that of awake examination on surgical decision making in OSA patients. However, it is also clear that the available published studies lack evidence on the association between this impact and surgical outcomes.

TI Reorganization and expansion of the nidoviral family Arteriviridae SO ARCHIVES OF VIROLOGY LA English DT Article ID SIMIAN HEMORRHAGIC-FEVER; EQUINE ARTERITIS VIRUS; RESPIRATORY SYNDROME VIRUS; SUBGENOMIC MESSENGER-RNAS; ISOLATE ATCC VR-2332; INTERNATIONAL COMMITTEE; STANDARDIZED NOMENCLATURE; TAXONOMIC PROPOSALS; RATIFICATION VOTE; SPECIES LEVEL AB The family Arteriviridae presently includes a single genus Arterivirus. This genus includes four species as the taxonomic homes for equine arteritis virus (EAV), lactate dehydrogenase-elevating virus (LDV), porcine respiratory and reproductive syndrome virus (PRRSV), and simian hemorrhagic fever virus (SHFV), respectively. A revision of this classification is urgently needed to accommodate the recent description of eleven highly divergent simian arteriviruses in diverse African nonhuman primates, one novel arterivirus in an African forest giant pouched rat, and a novel arterivirus in common brushtails in New Zealand. In addition, the current arterivirus nomenclature is not in accordance with the most recent version of the International Code of Virus Classification and Nomenclature. Here we outline an updated, amended, and improved arterivirus taxonomy based on current data. Taxon-specific sequence cut-offs are established relying on a newly established open reading frame 1b phylogeny and pairwise sequence comparison (PASC) of coding-complete arterivirus genomes. As a result, the current genus Arterivirus is replaced by five genera: Equartevirus (for EAV), Rodartevirus (LDV + PRRSV), Simartevirus (SHFV + simian arteriviruses), Nesartevirus (for the arterivirus from forest giant pouched rats), and Dipartevirus (common brushtail arterivirus). The current species Porcine reproductive and respiratory syndrome virus is divided into two species to accommodate the clear divergence of the European and American "types" of PRRSV, both of which now receive virus status. The current species Simian hemorrhagic fever virus is divided into nine species to accommodate the twelve known simian arteriviruses. Non-Latinized binomial species names are introduced to replace all current species names to clearly differentiate them from virus names, which remain largely unchanged.

This has increased interest in growing cellulosic biofuel feedstocks on marginal lands. Switchgrass (Panicum virgatum L.), a warm-season perennial, is a viable bioenergy crop candidate because it produces high yields on marginal lands under low fertility conditions. In other studies, switchgrass dry matter (DM) yields on marginal croplands varied from 5.0 to 10.0 Mg ha(-1) annually. West Virginia contains immense areas of reclaimed surface mined lands that could support a switchgrass-based biofuel industry, but yield data on these lands are lacking. Field experiments were established in 2008 to determine yields of three switchgrass cultivars on two West Virginia mine sites. One site reclaimed with topsoil and municipal sludge produced biomass yields of 19.0 Mg DM ha(-1) for Cave-in-Rock switchgrass after the sixth year, almost double the varieties Shawnee and Carthage, at 10.0 and 5.7 Mg ha(-1), respectively. Switchgrass yields on another site with no topsoil were 1.0 Mg ha(-1) after the sixth year, with little variation among cultivars. A second experiment was conducted at two other mine sites with a layer of topsoil over gray overburden. Cave-in-Rock was seeded with fertilizer applications of 0, 34, and 68 kg N-P2O5-K2O ha(-1). After the third year, the no fertilizer treatment averaged biomass yields of 0.3 Mg ha(-1), while responses to the other two rates averaged 1.1 and 2.0 Mg ha(-1), respectively. Fertilization significantly increased yields on reclaimed mine soils. Where mine soil fertility was good, yields were similar to those reported on agricultural soils in the Northeastern USA.

Our objective was to simultaneously evaluate factors influencing 4-year BMD change. Methods: This was a longitudinal cohort study of healthy, physically active women in the US Military Academy (n = 91; average age = 18.4 years). Assessments over four years included: height, weight, calcium intake, physical fitness, menstrual function (annual number cycles), oral contraceptives (OCs) or depotmedroxyprogesterone acetate (DMPA) use, and eating disorder behavior (Eating Disorder Inventory; (EDI)). BMD was measured annually at the lumbar spine and total hip by dual X-ray absorptiometry and calcaneal BMD by PIXI. Slope of 4 year BMD change at each skeletal site (spine total hip and calcaneus) was calculated for each woman. Results: BMD gains occurred at the spine in 50% and the hip in 36% of women. In unadjusted analyses, spine bone gain was positively related to menstrual cycle frequency (p = 0.04). Spine and hip BMD loss occurred in those using DMPA (p < 0.01) and those with the highest EDI quartile scores (p < 0.05). BMD change was unrelated to OC use. Hip and calcaneus BMD decreased with weight loss (average 4.8 + 2.2 lb/year) as compared to those with stable weight/weight gain (p < 0.05). In multivariable analysis, spine BMD increase was significantly related to African American (AA) race, normal EDI score and normal menses. Hip BMD increase was related to AA race, weight increase and normal menses. DMPA use was associated with spine, hip, and calcaneus bone loss. Conclusion: On average, BMD may modestly increase in college-aged women, in the absence of risk factors. However, risk factors including subclinical eating disorders, weight loss, menstrual dysfunction and DMPA use can have significant detrimental effects on BMD in young healthy physically active women.

However, these compounds are frequently found in the environment as components of mixtures that may also contain chlorinated ethanes and methanes. Under these conditions, the implementation of bioremediation may be complicated by inhibition effects, particularly when multiple dehalorespirers are present. We investigated the ability of the 1,1,2,2-tetrachloroethane (TeCA)-dechlorinating culture WBC-2 to biotransform TeCA alone, or a mixture of TeCA plus PCE and carbon tetrachloride (CT), in microcosms. The microcosms contained electron donors provided to biostimulate the added culture and sediment collected from a wetland where numerous "hotspots" of contamination with chlorinated solvent mixtures exist. The dominant TeCA biodegradation mechanism mediated by the WBC-2 culture in the microcosms was different in the presence of these wetland sediments than in the sediment-free enrichment culture or in previous WBC-2 bioaugmented microcosms and column tests conducted with wetland sediment collected at nearby sites. The co-contaminants and their daughter products also inhibited TeCA biodegradation by WBC-2. These results highlight the need to conduct biodegradability assays at new sites, particularly when multiple contaminants and dehalorespiring populations are present. (C) 2015 Elsevier Ltd.

The CNTs were grown on the E-glass fabric using a floating catalyst chemical vapor deposition procedure. The E-glass fabric with attached CNTs was then incorporated into resin based composites and compared to similar composites without CNTs. Long and short beam bending tests, uniaxial compression measurements for energy dissipation, high strain-rate Split Hopkinson pressure bar measurements, and ballistic performance (V50) tests were performed to characterize the mechanical properties of the CNT composites. The CNT composites showed a reduction in interlaminar shear strength by 25.9%. They also showed an increase in the specific energy absorption by 106% at high strain rates and an increase in energy density dissipation by 643% after 5 cycles at quasi static strain rates. In ballistic V50 tests, the CNT based composites showed a higher V50 value by 11.1%. Due to their reduced weight and energy dissipation properties, the direct growth of CNTs on E-glass fabrics incorporated into composites have potential defense applications such as blast protection.

It suggests that James Madison drew inspiration for innovative elements of the American Constitution from the Achaean League. It also claims that attention to Madison's debts, which he tallied in both Federalist no. 18 and the earlier 'Notes on Ancient and Modem Confederacies,' helps us to appreciate what Madison took to be perhaps the most innovative feature of the American founding not necessarily the Constitution that was established, but the manner in which its establishment was recorded and defended.

By utilizing improved turbulence and heat transfer sub-models, the combustion and heat transfer characteristics of the engine were satisfactorily reproduced for operation under conventional diesel combustion, homogeneous charge compression ignition, and reactivity controlled compression ignition regimes. The results indicated that the total heat transfer losses of conventional diesel combustion are the largest among the three combustion regimes due to the direct interaction of the high-temperature flame with the piston wall, while the heat transfer losses of reactivity controlled compression ignition are the lowest and nearly are independent of combustion phasing because of the avoidance of high-temperature regions adjacent to the cylinder walls. Compared to conventional diesel combustion, homogeneous charge compression ignition shows more potential for the reduction of exhaust energy and improvement of fuel efficiency. In reactivity controlled compression ignition combustion, the reduction of heat transfer and exhaust losses outweigh its increase in combustion losses and offer the opportunity for further improvement of fuel efficiency. Furthermore, by evaluating the widely used Woschni and Chang et al.'s empirical heat transfer correlations, it was found that both correlations considerably overestimate the heat transfer rate for the reactivity controlled compression ignition regime. It is necessary to improve empirical heat transfer models to take account of the flow and combustion characteristics under various combustion modes.

Untreated concomitant posterolateral corner (PLC) injury is an identified cause of failed ACL reconstruction; however, the injury pattern has yet to be defined for the paediatric population. Methods Magnetic resonance imaging (MRI) studies of the knee performed between 1 January 2009 and 1 January 2013 were retrospectively reviewed. Imaging reports indicating an intra-substance injury of the ACL were reviewed, and all associated injured structures were recorded. Injury patterns were categorised by age, gender, physis status and associated injuries. Logistic regression and chi-square analyses compared ACL disruptions with and without concomitant PLC injuries. Results One hundred and twenty-eight patients (74 boys and 54 girls, average age 15.27 years) sustained an ACL disruption. Concomitant injury to the PLC was seen in 13.3 % of injuries. Associated PLC injuries were significantly associated with lateral meniscus injury and Segond fractures. Lateral meniscus injury was predictive of PLC injury (p= 0.05) upon logistic regression analysis. Conclusion Concomitant PLC injuries were found in 13.3 % of all ACL disruptions on MRI analysis. Lateral meniscus injuries associated with an ACL disruption were predictive of concomitant PLC injury. Combined injury of the ACL and lateral meniscus should prompt close scrutiny to PLC structures.

Although recent analytical advances are rapidly improving taxonomic annotations, identifying functional darkmatter remains problematic. Here, we apply paired metaproteomics and dsDNA-targeted metagenomics to identify 1,875 virion-associated proteins from the ocean. Over one-half of these proteins were newly functionally annotated and represent abundant and widespread viral metagenome-derived protein clusters (PCs). One primarily unannotated PC dominated the dataset, but structural modeling and genomic context identified this PC as a previously unidentified capsid protein from multiple uncultivated tailed virus families. Furthermore, four of the five most abundant PCs in the metaproteome represent capsid proteins containing the HK97-like protein fold previously found in many viruses that infect all three domains of life. The dominance of these proteins within our dataset, as well as their global distribution throughout the world's oceans and seas, supports prior hypotheses that this HK97-like protein fold is the most abundant biological structure on Earth. Together, these culture-independent analyses improve virion-associated protein annotations, facilitate the investigation of proteins within natural viral communities, and offer a high-throughput means of illuminating functional viral dark matter.

From a regulatory perspective, it is of crucial importance to determine the confidence for the AOP in question as well as the quality of data available in supporting this evaluation. A weight of evidence approach has been proposed for this task, but many of the existing frameworks for weight of evidence evaluation are qualitative and there is not clear guidance regarding how weight of evidence should be calculated for an AOP. In this paper we advocate the use of a subject matter expertise driven approach for weight of evidence evaluation based on criteria and metrics related to data quality and the strength of causal linkages between key events. As a demonstration, we notionally determine weight of evidence scores for two AOPs: Non-competitive ionotropic GABA receptor antagonism leading to epileptic seizures, and Antagonist-binding and stabilization of a co-repressor to the peroxisome proliferator-activated receptor alpha (PPAR alpha) signaling complex ultimately causing starvation like weight loss.

The functional importance of KIR-HLA interactions has been demonstrated for a number of chronic viral infections, but to date only a few studies have been performed in the context of acute self-limited viral infections. During our investigation of CD8(+) T cell responses to a conserved HLA-B57-restricted epitope derived from dengue virus (DENV) non-structural protein-1 (NS1), we observed substantial binding of the tetrameric complex to non-T/non-B lymphocytes in peripheral blood mononuclear cells (PBMC) from a long-standing clinical cohort in Thailand. We confirmed binding of the NS1 tetramer to CD56(dim) NK cells, which are known to express KIRs. Using depletion studies and KIR-transfected cell lines, we demonstrated further that the NS1 tetramer bound the inhibitory receptor KIR3DL1. Phenotypical analysis of PBMC from HLA-B57(+) subjects with acute DENV infection revealed marked activation of NS1 tetramer-binding natural killer (NK) cells around the time of defervescence in subjects with severe dengue disease.

We suggest that the reason some judge such scenarios as wrong (using intuitive feelings) and others do not (using deliberative reasons) is due to an important motivational distinction. Consistent with this view, across 7 studies, we demonstrate that negative judgments of such moral scenarios are more intense when processed in the promotion focus compared to the prevention focus, and that this is due to differences in whether eager (intuitive feelings) versus vigilant (deliberative reasons) means are employed in judging these moral wrongs. By examining both boundary conditions and possible underlying mechanisms for regulatory focus differences in moral judgment intensity, we expand our understanding of the differences between promotion and prevention regarding how proscriptive judgments are processed, while integrating these differences with existing theories in moral psychology.

A growing problem for dam owners is the aging of such structures. As spillway systems age, more rigorous maintenance, inspection/testing, and repair/replacement of parts are required to ensure their long-term safe operation. Executing these measures may be very costly to dam owners and, if not conducted appropriately, may not have the desired effect on the reliability of the system. The first objective of this paper is to investigate the effect of inspection, testing, repair, and replacement strategies on the availability of spillway gate components. The second objective is to model the availability of the entire spillway gate system under flood and load rejection scenarios to determine the ability of the system as a whole to operate safely under emergency conditions. These two objectives are then used with cost optimization to develop recommendations on the type and frequency of inspections and tests for different types of spillway gate systems. A software application was developed to achieve the objectives by modeling the spillway gate components and system, determining component/system unavailability based on type and frequency of inspections/tests, and obtaining the optimum inspection/testing strategy.

TI A Survey of Mechanical Ventilator Practices Across Burn Centers in North America SO JOURNAL OF BURN CARE & RESEARCH LA English DT Article ID RESPIRATORY-DISTRESS-SYNDROME; ACUTE LUNG INJURY; FREQUENCY PERCUSSIVE VENTILATION; RANDOMIZED CONTROLLED-TRIAL; END-EXPIRATORY PRESSURE; INHALATION INJURY; OSCILLATORY VENTILATION; TIDAL VOLUMES; TRACHEOSTOMY; METAANALYSIS AB Burn injury introduces unique clinical challenges that make it difficult to extrapolate mechanical ventilator (MV) practices designed for the management of general critical care patients to the burn population. We hypothesize that no consensus exists among North American burn centers with regard to optimal ventilator practices. The purpose of this study is to examine various MV practice patterns in the burn population and to identify potential opportunities for future research. A researcher designed, 24-item survey was sent electronically to 129 burn centers. The (2), Fisher's exact, and Cochran-Mantel-Haenszel tests were used to determine if there were significant differences in practice patterns. We analyzed 46 questionnaires for a 36% response rate. More than 95% of the burn centers reported greater than 100 annual admissions. Pressure support and volume assist control were the most common initial MV modes used with or without inhalation injury. In the setting of Berlin defined mild acute respiratory distress syndrome (ARDS), ARDSNet protocol and optimal positive end-expiratory pressure were the top ventilator choices, along with fluid restriction/diuresis as a nonventilator adjunct. For severe ARDS, airway pressure release ventilation and neuromuscular blockade were the most popular. The most frequently reported time frame for mechanical ventilation before tracheostomy was 2 weeks (25 of 45, 55%); however, all respondents reported in the affirmative that there are certain clinical situations where early tracheostomy is warranted. Wide variations in clinical practice exist among North American burn centers. No single ventilator mode or adjunct prevails in the management of burn patients regardless of pulmonary insult. Movement toward American Burn Association-supported, multicenter studies to determine best practices and guidelines for ventilator management in burn patients is prudent in light of these findings.

Given a large edge-labeled network, e.g., a time-evolving network, how can we find interesting patterns? We propose Com , a novel, fast and incremental tensor analysis approach which can discover communities appearing over subsets of the labels. The method is (a) scalable, being linear on the input size, (b) general, (c) needs no user-defined parameters and (d) effective, returning results that agree with intuition. We apply our method to real datasets, including a phone call network, a computer-traffic network and a flight information network. The phone call network consists of 4 million mobile users, with 51 million edges (phone calls), over 14 days, while the flights dataset consists of 7733 airports and 5995 airline companies flying 67,663 different routes. We show that Com spots intuitive patterns regarding edge labels that carry temporal or other discrete information. Our findings include large "star"-like patterns, near-bipartite cores, as well as tiny groups (five users), calling each other hundreds of times within a few days. We also show that we are able to automatically identify competing airline companies.

TI Surrogate modeling for peak or time-dependent storm surge prediction over an extended coastal region using an existing database of synthetic storms SO NATURAL HAZARDS LA English DT Article DE Surrogate model; Kriging; Principal component analysis; Time-dependent output; Storm surge; High-fidelity hurricane surge model ID RESPONSE FUNCTION-APPROACH; HAZARD ASSESSMENT; RISK-ASSESSMENT; WAVE; ATTRIBUTES; SIMULATION; HURRICANES; WIND AB This paper investigates the development of a kriging surrogate model for storm surge prediction utilizing an existing database of high-fidelity, synthetic storms. This surrogate model (metamodel) provides a fast-to-compute mathematical approximation to the input/output relationship of the computationally expensive simulation model that created this database. The implementation is considered over a large coastal region composed of nearshore nodes (locations where storm surge is predicted) and further examines the ability to provide time-series forecasting. This setting creates a high-dimensional output (over a few thousand surge responses) for the surrogate model with anticipated high spatial/temporal correlation. Kriging is considered as a surrogate model, and special attention is given to the appropriate parameterization of the synthetic storms, based on the characteristics of the given database, to determine the input for the metamodel formulation. Principal component analysis (PCA) is integrated in this formulation as a dimension reduction technique to improve computational efficiency, as well as to provide accurate and continuous predictions for time-dependent outputs without the need to introduce time averaging in the time-series forecasting. This is established by leveraging the aforementioned correlation characteristics within the initial database. A range of different implementation choices is examined within the integrated kriging/PCA setting, such as the development of single or multiple metamodels for the different outputs. The metamodel accuracy for inland nodes that have remained dry in some of the storms in the initial database is also examined. The performance of the surrogate modeling approach is evaluated through a case study, utilizing a database of 446 synthetic storms for the Gulf of Mexico (Louisiana coast). The output considered includes time histories for 30 locations over a period of 45.5 h with 92 uniform time steps, as well as peak responses over a grid of 545,635 nearshore nodes. High accuracy and computational efficiency are observed for the proposed implementation, whereas including the prediction error statistics provides estimations with significant safety margins.

In a previous study, it was shown that by adjusting various compositional and nano-structural properties of both inorganic xerogels and polymers, zero-order release kinetics over 7 days can be achieved in vitro. In this study, in vitro release properties are confirmed in vivo using a model that tests for actual functionality of the released local anesthetics. Composite materials made with tyrosine-polyethylene glycol(PEG)-derived poly(ether carbonate) copolymers and silica-based sol-gel (xerogel) were synthesized. The in vivo release from the composite controlled release materials was demonstrated by local anesthetics delivery in a rat incisional pain model. The tactile allodynia resulting from incision was significantly attenuated in rats receiving drug-containing composites compared with the control and sham groups for the duration during which natural healing had not yet taken place. The concentration of drug (bupivacaine) in blood is dose dependent and maintained stable up to 120 h post-surgery, the longest time point measured. These in vivo studies show that polymer-xerogel composite materials with controlled release properties represent a promising class of controlled release materials for pain management.

Two fibers were laid parallel and compressed between two tool steel platens. The new experimental setup ensures that the individual fibers are being compressed evenly along the length and that the platens are parallel during compression. Nominal stress-strain curves were obtained for quasi-static loading of both types of fibers. To evaluate the rate effects on the transverse behavior, high-rate transverse compression experiments were also performed using a miniature Kolsky bar loading on single-fiber specimens to obtain the corresponding stress-strain response of these high performance fibers at high rates of deformation.

TI Comprehensive Evaluation of Neuroprotection Achieved by Extended Selective Brain Cooling Therapy in a Rat Model of Penetrating Ballistic-Like Brain Injury SO THERAPEUTIC HYPOTHERMIA AND TEMPERATURE MANAGEMENT LA English DT Article ID NONDISRUPTIVE AXONAL INJURY; RANDOMIZED CONTROLLED-TRIAL; POSTTRAUMATIC HYPOTHERMIA; MODERATE HYPOTHERMIA; INTRACEREBRAL HEMORRHAGE; STATUS EPILEPTICUS; MILD HYPOTHERMIA; INFLAMMATION; SEIZURES; TRAUMA AB Brain hypothermia has been considered as a promising alternative to whole-body hypothermia in treating acute neurological disease, for example, traumatic brain injury. Previously, we demonstrated that 2-hours selective brain cooling (SBC) effectively mitigated acute (<= 24 hours postinjury) neurophysiological dysfunction induced by a penetrating ballistic-like brain injury (PBBI) in rats. This study evaluated neuroprotective effects of extended SBC (4 or 8 hours in duration) on sub-acute secondary injuries between 3 and 21 days postinjury (DPI). SBC (34 degrees C) was achieved via extraluminal cooling of rats' bilateral common carotid arteries (CCA). Depending on the experimental design, SBC was introduced either immediately or with a 2- or 4-hour delay after PBBI and maintained for 4 or 8 hours. Neuroprotective effects of SBC were evaluated by measuring brain lesion volume, axonal injury, neuroinflammation, motor and cognitive functions, and post-traumatic seizures. Compared to untreated PBBI animals, 4 or 8 hours SBC treatment initiated immediately following PBBI produced comparable neuroprotective benefits against PBBI-induced early histopathology at 3 DPI as evidenced by significant reductions in brain lesion volume, axonal pathology (beta-amyloid precursor protein staining), neuroinflammation (glial fibrillary acetic protein stained-activated astrocytes and rat major histocompatibility complex class I stained activated microglial cell), and post-traumatic nonconvulsive seizures. In the later phase of the injury (7-21 DPI), significant improvement on motor function (rotarod test) was observed under most SBC protocols, including the 2-hour delay in SBC initiation. However, SBC treatment failed to improve cognitive performance (Morris water maze test) measured 13-17 DPI. The protective effects of SBC on delayed axonal injury (silver staining) were evident out to 14 DPI. In conclusion, the CCA cooling method of SBC produced neuroprotection measured across multiple domains that were evident days/weeks beyond the cooling duration and in the absence of overt adverse effects. These proof-of-concept results suggest that SBC may provide an attractive neuroprotective approach for clinical considerations.

Immune activation during acute infection is driven by many factors including pyroptosis, replicative capacity of the infecting virus, and loss of Th17 cells within the gut. Early antiretroviral therapy (ART), particularly if initiated in Fiebig I (HIV IgM-), preserved mucosal CD4(+) T cells, possibly preventing the release of microbial products associated with immune activation. Viral reservoirs were restricted by the early initiation of ART, and heightened systemic immune activation was partially prevented compared with chronic HIV infection. A strong correlation was found between the size of the viral reservoir and cellular immune activation.SummaryThe timing of immune activation during acute infection occurs shortly after exposure. Recent studies demonstrated that ART mitigates inflammatory responses, preserves CD4(+) T cells, and limits reservoir seeding if provided early in acute HIV infection.

In the coating process, we used three different polysiloxane materials containing different amine groups including, 35-45% (trimethylammoniummethylphenythyl)-methyl siloxane-55-65% dimethyl siloxane copolymer chloride salt (QMS-435), aminoethylaminopropyl silsesquioxane-methylsilsesquioxane copolymer oligomer (WSA-7021) and aminopropyl silesquioxane oligomers (WSA-991), as a positive polyelectrolyte. Thermo-gravimetric analysis showed that coated fabric has char yield around 40% at 600 degrees C whereas control fabric was completely consumed. The vertical flame test (VFT) on the LbL-coated Nyco fabric was passed with after flame time, 2s, and the char length of 3.81cm. Volatile and nontoxic degradation products of flame retardant-coated fabric were analyzed by pyrolysis gas chromatography mass spectroscopy (Py-GCMS). Surface morphology of coated fabrics and burned fabric residues were studied by scanning electron microscopy. Copyright (c) 2014 John Wiley & Sons, Ltd.

TI Failure processes governing high-rate impact resistance of epoxy resins filled with core-shell rubber nanoparticles SO JOURNAL OF MATERIALS SCIENCE LA English DT Article ID ELASTOMER-MODIFIED EPOXIES; CROSS-LINK DENSITY; HIGH-STRAIN RATES; TOUGHENING MECHANISMS; FRACTURE-TOUGHNESS; BALLISTIC IMPACT; DEFORMATION-BEHAVIOR; SILICA NANOPARTICLES; ENERGY-DISSIPATION; TRIBLOCK COPOLYMER AB Epoxy resins are classically toughened by rubber additives, but the effectiveness of rubber toughening tends to diminish with increasing strain rate, decreasing temperature, and decreasing matrix ductility. In this study, we demonstrate that low loadings of 100-200-nm core-shell rubber (CSR) particulate additives can improve high strain rate (10(4)-10(5) s(-1)) impact resistance by nearly 200 % for epoxy resins with glass transition temperatures T (g) in a range between 60 and 110 A degrees C, without large reductions in T (g) or stiffness. In addition, CSR additives improve low-temperature impact resistance of the epoxies down to 0 A degrees C. Size and surface chemistry of the CSR particles influence the ballistic response, with 200-nm diameter, weakly bound, and poorly dispersed CSR particles providing the greatest toughening performance at low filler loadings and high rates. Impact resistance for a systematic series of CSR-modified epoxies covers a transition from brittle to tough behavior, where the failure mechanism changes with effective fracture resistance. For brittle resins, failure is dominated by initiation of Hertzian cone fracture which depends strongly on fracture toughness K (IC), while for tough resins, failure is dominated by plastic yield at the impact site and is independent of fracture toughness above a minimum K (IC) value of approximately 1.2-1.5 MPa m(1/2). Interestingly, quasistatic mechanical properties are reasonably effective qualitative predictors of high-rate impact resistance, suggesting that the toughening mechanisms of CSR particles are similar over the rates studied here. The insights gained from this study are valuable for design of next generation adhesives, polymers, and polymer composite matrices for lightweight protective applications.

CO32- substituted HAP (HAP-CO3) has showed enhanced oxide ion conductivity than bare HAP in high temperature solid oxide fuel cells. Substitutions for both cations and anions in HAP structure (Pb-HAP-CO3) are promising to integrate the catalytic property of Pb-HAP and oxide ion conductive property of HAP-CO3 into one apatite-based ceramic material that can be manufactured into membrane reactors for possessing CH4 activation and O-2 permeation capabilities for efficient OCM reactions. In this work, the effects of substitutions for both cation (Pb2+) and anion (CO32-) in HAP structure on OCM reactions were studied. The composition and physicochemical properties of HAP catalysts were changed by the cation and anion substitutions, respectively, and as consequences, they influenced the catalytic performances of HAP structure in OCM reactions. The selectivity to C-2 (ethylene and ethane) products increased in the order of HAP-CO3 < HAP < Pb-HAP-CO3 < Pb-HAP, while Pb-HAP-CO3 showed the best stability and comparable C-2 yield (under optimized reaction conditions) to Pb-HAP catalyst. Under different reaction temperature and/or CH4/O-2 ratio in the OCM reactions, the CH4 conversion and C-2 or COx (CO and CO2) selectivity showed a strong dependence on the composition of HAP-based catalysts. The present study forms a basis for understanding of the correlations between the composition, structure, and catalytic performance of HAP and other apatite structured catalysts, which are potential membrane materials for OCM reactions in membrane reactors.

Shucked abalone meats were processed at 100 or 300 MPa for 5 or 10min, and stored at 2 degrees C for 35 days. Treatments were analyzed for aerobic plate count (APC), total volatile base nitrogen (TVBN), K-value, biogenic amines, color, and texture. APC did not exceed 10(6) and TVBN levels remained below 35 mg/100 g for 35 days for the 300 MPa treatments. No biogenic amines were detected in the 300 MPa treatments, but putrescine and cadaverine were detected in the control and 100 MPa treatments. Color and texture were not affected by HPP or storage time. These results indicate that post-rigor processing at 300 MPa for 10 min can significantly increase refrigerated shelf-life of abalone without affecting chemical or physical quality characteristics important to consumers.

After respiratory exposure, Bm establishes itself within host macrophages before spreading into major organ systems, which can lead to chronic infection, sepsis, and death. Previously, we combined computational prediction of host-pathogen interactions with yeast two-hybrid experiments and identified novel virulence factor genes in Bm, including BMAA0553, BMAA0728 (tssN), and BMAA1865. In the present study, we used recombinant allelic exchange to construct deletion mutants of BMAA0553 and tssN (Delta BMAA0553 and Delta TssN, respectively) and showed that both deletions completely abrogated virulence at doses of >100 times the LD50 of the wild-type Bm strain. Analysis of Delta BMAA0553- and Delta TssN-infected mice showed starkly reduced bacterial dissemination relative to wild-type Bm, and subsequent in vitro experiments characterized pathogenic phenotypes with respect to intracellular growth, macrophage uptake and phagosomal escape, actin-based motility, and multinucleated giant cell formation. Based on observed in vitro and in vivo phenotypes, we explored the use of Delta TssN as a candidate live-attenuated vaccine. Mice immunized with aerosolized Delta TssN showed a 21-day survival rate of 67% after a high-dose aerosol challenge with the wild type Bm ATCC 23344 strain, compared to a 0% survival rate for unvaccinated mice. However, analysis of histopathology and bacterial burden showed that while the surviving vaccinated mice were protected from acute infection, Bm was still able to establish a chronic infection. Vaccinated mice showed a modest IgG response, suggesting a limited potential of Delta TssN as a vaccine candidate, but also showed prolonged elevation of pro-inflammatory cytokines, underscoring the role of cellular and innate immunity in mitigating acute infection in inhalational glanders.

TI Conceptual approaches for treatment of phosgene inhalation-induced lung injury SO TOXICOLOGY LETTERS LA English DT Article DE Phosgene; Inhalation; Whole-body; Mechanism; Survival; Treatment; Toxicity; Mice; Exposure ID SMOOTH-MUSCLE-CELLS; ION-CHANNEL TRPA1; ENDOTHELIAL-CELLS; NITRIC-OXIDE; CALCIUM-CHANNELS; PULMONARY-EDEMA; CARDIOVASCULAR-SYSTEM; COVALENT MODIFICATION; CA2+ CURRENTS; UP-REGULATION AB Toxic industrial chemicals are used throughout the world to produce everyday products such as household and commercial cleaners, disinfectants, pesticides, pharmaceuticals, plastics, paper, and fertilizers. These chemicals are produced, stored, and transported in large quantities, which poses a threat to the local civilian population in cases of accidental or intentional release. Several of these chemicals have no known medical countermeasures for their toxic effects. Phosgene is a highly toxic industrial chemical which was used as a chemical warfare agent in WWI. Exposure to phosgene causes latent, non-cardiogenic pulmonary edema which can result in respiratory failure and death. The mechanisms of phosgene-induced pulmonary injury are not fully identified, and currently there is no efficacious countermeasure. Here, we provide a proposed mechanism of phosgene-induced lung injury based on the literature and from studies conducted in our lab, as well as provide results from studies designed to evaluate survival efficacy of potential therapies following whole-body phosgene exposure in mice. Several therapies were able to significantly increase 24 h survival following an LCt(50-70) exposure to phosgene; however, no treatment was able to fully protect against phosgene-induced mortality. These studies provide evidence that mortality following phosgene toxicity can be mitigated by neuro- and calcium-regulators, antioxidants, phosphodiesterase and endothelin receptor antagonists, angiotensin converting enzymes, and transient receptor potential cation channel inhibitors. However, because the mechanism of phosgene toxicity is multifaceted, we conclude that a single therapeutic is unlikely to be sufficient to ameliorate the multitude of direct and secondary toxic effects caused by phosgene inhalation.

Ion channels of the transient receptor potential (TRP) family have been identified to act as specific chemosensory molecules in the respiratory tract in the detection, control of adaptive responses and initiation of detrimental signaling cascades upon exposure to various toxic inhalation hazards (TIH); their activation due to TIH exposure may result in broncho- and vasoconstriction. We studied changes in the regulation of intracellular free Ca2+ concentration ([Ca2+](i)) in cultures of human bronchial smooth muscle cells (BSMC) and human pulmonary microvascular endothelial cells (HPMEC) exposed to CG (16 ppm, 8 min), using an air/liquid interface exposure system. CG increased [Ca2+](i) (p < 0.05) in both cell types, The CG-induced [Ca2+](i) was blocked (p < 0.05) by two types of TRP channel blockers, SKF-96365, a general TRP channel blocker, and RR, a general TRPV (vanilloid type) blocker, in both BSMC and HPMEC. These effects correlate with the in vivo efficacies of these compounds to protect against lung injury and 24 h lethality from whole body CG inhalation exposure in mice (8-10 ppm x 20 min). Thus the TRP channel mechanism appears to be a potential target for intervention in CG toxicity. Published by Elsevier Ireland Ltd.

T-s >= 800 degrees C leads to epitaxial layers with a cube-on-cube relationship to the substrate: (001)(NbN) parallel to(001)(MgO) and [100](NbN)parallel to[100](MgO). The layers are nearly stoichiometric with x = 0.95-0.98 for T-s <= 800 degrees C, but become nitrogen deficient with x = 0.81 and 0.91 for T-s = 900 and 1000 degrees C. X-ray diffraction reciprocal space maps indicate a small in-plane compressive strain of-0.0008 +/- 0.0004 for epitaxial layers, and a relaxed lattice constant that decreases from 4372 A for x = 0.81 to 4363 A for x = 0.98. This unexpected trend is attributed to increasing Nb and decreasing N vacancy concentrations, as quantified by first-principles calculations of the lattice parameter vs. point defect concentration, and consistent with the relatively small calculated formation energies for N and Nb vacancies of 1.00 and-0.67 eV at 0 K and-0.53 and 0.86 eV at 1073 K, respectively. The N-deficient NbN0.81(001) layer exhibits the highest crystalline quality with in-plane and out-of-plane x-ray coherence lengths of 4.5 and 13.8 nm, attributed to a high Nb-adatom diffusion on an N-deficient growth front. However, it also contains inclusions of hexagonal NbN grains which lead to a relatively high measured hardness H = 28.0 +/- 5.1 GPa and elastic modulus E = 406 +/- 70 GPa. In contrast, the nearly stoichiometric phase-pure epitaxial cubic NbN0.98(001) layer has a H = 17.8 +/- 0.7 GPa and E = 315 +/- 13 GPa. The latter value is slightly smaller than 335 and 361 GPa, the isotropic elastic modulus and the [100]-indentation modulus, respectively, predicted for NbN from the calculated c(11) = 641 GPa, c(12) = 140 GPa, and c(44) = 78 GPa. The electrical resistivity ranges from 171 to 437 mu Omega cm at room temperature and 155-646 mu Omega cm at 77 K, suggesting carrier localization due to disorder from vacancies and crystalline defects.

TI Small-World Propensity and Weighted Brain Networks SO SCIENTIFIC REPORTS LA English DT Article ID COMPLEX NETWORKS; FUNCTIONAL CONNECTIVITY; COMMUNITY STRUCTURE; PREFRONTAL CORTEX; ORGANIZATION; SCHIZOPHRENIA; NEURODEVELOPMENT; ARCHITECTURE; MODEL AB Quantitative descriptions of network structure can provide fundamental insights into the function of interconnected complex systems. Small-world structure, diagnosed by high local clustering yet short average path length between any two nodes, promotes information flow in coupled systems, a key function that can differ across conditions or between groups. However, current techniques to quantify small-worldness are density dependent and neglect important features such as the strength of network connections, limiting their application in real-world systems. Here, we address both limitations with a novel metric called the Small-World Propensity (SWP). In its binary instantiation, the SWP provides an unbiased assessment of small-world structure in networks of varying densities. We extend this concept to the case of weighted brain networks by developing (i) a standardized procedure for generating weighted small-world networks, (ii) a weighted extension of the SWP, and (iii) a method for mapping observed brain network data onto the theoretical model. In applying these techniques to compare realworld brain networks, we uncover the surprising fact that the canonical biological small-world network, the C. elegans neuronal network, has strikingly low SWP. These metrics, models, and maps form a coherent toolbox for the assessment and comparison of architectural properties in brain networks.

We derive fundamental limits to the optical response of absorptive systems, bounding the largest enhancements possible given intrinsic material losses. Through basic conservation-of-energy principles, we derive geometry-independent limits to per-volume absorption and scattering rates, and to local-density-of-states enhancements that represent the power radiated or expended by a dipole near a material body. We provide examples of structures that approach our absorption and scattering limits at any frequency; by contrast, we find that common "antenna" structures fall far short of our radiative LDOS bounds, suggesting the possibility for significant further improvement. Underlying the limits is a simple metric, vertical bar x vertical bar(2)/Im x for a material with susceptibility x, that enables broad technological evaluation of lossy materials across optical frequencies.

How TNF regulates disability during progressive disease remains unresolved. Using a progressive EAE model characterized by sustained TNF and increasing morbidity, this study evaluates the role of unregulated TNF in exacerbating central nervous system (CNS) pathology and inflammation. Methods: Progressive MS was mimicked by myelin oligodendrocyte glycoprotein (MOG) peptide immunization of mice expressing a dominant negative IFN-gamma receptor alpha chain under the human glial fibrillary acidic protein promoter (GFAP gamma R1 Delta). Diseased GFAP gamma R1 Delta mice were treated with anti-TNF or control monoclonal antibody during acute disease to monitor therapeutic effects on sustained disability, demyelination, CNS inflammation, and blood brain barrier (BBB) permeability. Results: TNF was specifically sustained in infiltrating macrophages. Anti-TNF treatment decreased established clinical disability and mortality rate within 7 days. Control of disease progression was associated with a decline in myelin loss and leukocyte infiltration, as well as macrophage activation. In addition to mitigating CNS inflammation, TNF neutralization restored BBB integrity and enhanced CNS anti-inflammatory responses. Conclusions: Sustained TNF production by infiltrating macrophages associated with progressive EAE exacerbates disease severity by promoting inflammation and disruption of BBB integrity, thereby counteracting establishment of an anti-inflammatory environment required for disease remission.

TI Integration of ecosystem-based models into an existing interactive web-based tool for improved aquaculture decision-making SO AQUACULTURE LA English DT Article DE Shellfish; Aquaculture; GIS; Decision support tool ID DATA-POOR ENVIRONMENTS; SHELLFISH AQUACULTURE; CARRYING-CAPACITY; SITE SELECTION; MANAGEMENT; CULTURE; ESTUARY; GIS; INDICATORS; SOUND AB Proper site selection is critical to the development and expansion of marine aquaculture. Major considerations for site selection include: potential for competing uses, environmental interactions, and animal productivity. Two types of existing site selection tools, mapping and modeling, have proven useful independently, and in some recent studies have proven useful when used together. GIS-based mapping tools have become important in the decision-making process. These tools provide access to marine and coastal datasets allowing farmers and extension agents to gather information on availability of cultivation sites. They are also used by resource managers to assess potential use conflicts (e.g. existence of commercial fishing, mooring areas, fixed fishing gear) and possible environmental interactions (e.g. presence of seagrasses, contaminants, threatened or endangered species). Models have been used separately to predict animal growth, farm productivity, and farm-related effects on the surrounding water and sediment quality. The integration of the Farm Aquaculture Resource Management (FARM) model (http://www.farmscale.org) into the U.S. state of Connecticut's Aquaculture Mapping Atlas (http://seagrant.uconn.edu/whatwedo/aquaculture/shellmap.php) was tested in three geographically distinct waterbodies within Connecticut (CT) waters of Long Island Sound. Nearshore waters within the towns of Mystic, Milford, and Westport were selected as pilot locations to determine usability and capability of the combined tools. Data from two long-term offshore sampling stations adjacent to existing shellfish leases were used to test spatial and temporal sampling variability impacts on model results. Partnerships with local monitoring programs and growers were important for acquisition of water quality data, oyster measurement data, and information about local culture practices. All sites were deemed suitable for oyster aquaculture based on model results that predicted Moderate to High growth based on estimated time to reach harvest size from one in (2.54 cm) seed oysters (Crassostrea virginica). Time to harvest varied from 282 days (High growth) to 645 days (Moderate growth) among the 22 stations in the three nearshore sites, and 724-956 days (Moderate growth) at the two offshore sites. Results from the two long-term offshore stations indicate that data from the same year must be used when comparing production-based suitability of sites. Addition of potential production estimates improved the ability to select between suitable mapping-based sites. This mapping and modeling combination should be encouraged to provide a strong basis for successful siting and expansion of aquaculture while minimizing user conflict and adverse environmental interactions. This approach may be particularly useful in waterbodies where shellfish aquaculture is possible but is not well established. Published by Elsevier B.V.

A wide range of fluid intakes are compatible with euhydration, whereby total body water varies narrowly from day to day by 600 to 900mL (<1% body mass). One measure of fluid intake adequacy involves enough fluid to prevent meaningful body water deficits outside this euhydration range (i.e., dehydration). Another measure of fluid intake adequacy involves enough fluid to balance the renal solute load, which can vary widely inside the euhydration range. The subtle but important distinction between the 2 types of adequacy may explain some of the ambiguity surrounding the efficacy of hydration status markers. Both perspectives of fluid intake adequacy are discussed in detail and a simple tool is reviewed that may help healthy, active, low-risk populations answer the question, Am I drinking enough?Key Teaching Points center dot Adequate fluid intake can be dually defined as a volume of fluid (from water, beverages, and food) sufficient to replace water losses and provide for solute excretion.center dot Fluid needs can differ greatly among individuals due to variation in the factors that influence both water loss and solute balance; thus, adequacy is consistent with a wide range of fluid intakes and is better gauged using hydration assessment methods.center dot Adequacy of fluid intake for replacing meaningful water losses (dehydration) can be assessed simply, inexpensively, and with reasonable fidelity among healthy, active, low-risk individuals.center dot Adequacy of fluid intake for solute excretion per se can also be assessed among individuals but is more difficult to define and less practical to measure.

South African family physicians provided 42 responses via a social media and online survey. Two word cloud images were created based on two iconsrecognised as being truly South African around the world - that of the national flag and former president Nelson Mandela. The #1WorldforFamilyMedicine initiative was promoted by the World Organization of Family Doctors across the globe to help celebrate World Family Doctor Day on 19 May 2015. To date, over 70 images have been created in 50 different countries on six continents. The images represent family physicians' love for their profession and the community they serve.

During transient periods of inattention, drivers may shift their attention towards internally-directed thoughts or feelings at the expense of staying focused on the road. This study examined whether increasing task difficulty by manipulating involved sensory modalities as the driver detected the lane-departure in a simulated driving task would promote a shift of brain activity between different modes of processing, reflected by brain network dynamics on electroencephalographic sources. Results showed that depriving the driver of salient sensory information imposes a relatively more perceptually-demanding task, leading to a stronger activation in the task-positive network. When the vehicle motion feedback is available, the drivers may rely on vehicle motion to perceive the perturbations, which frees attentional capacity and tends to activate the default mode network. Such brain network dynamics could have major implications for understanding fluctuations in driver attention and designing advance driver assistance systems.

This study reports charge, conviction, and prosecution rates for trauma patients at 2 level I trauma centers servicing a large metropolitan city. Methods: A retrospective review of the trauma databases was completed to identify patients meeting inclusion criteria. Four hundred sixty patients were identified and their records were compared with the district attorney's records for DUI charges and convictions. Results: The conviction rate for this study was 8.7%, demonstrating continued low rates of conviction despite growing interest and public awareness of drinking and driving. Conclusions: We discuss legal considerations that providers should consider when treating patients who have been drinking and driving.

Using a combination of angle-resolved ultraviolet photoemission and angle-resolved two-photon photoemission (AR-2PPE) spectroscopy, we characterize the band structure of bulk SnS2. Comparison with density functional theory calculations shows excellent quantitative agreement in the valence band region and reveals several localized bands that likely originate from defects such as sulfur vacancies. Evidence for a moderate density of defects is also observed by AR-2PPE in the conduction band region, leading to localized bands not present in the computational results. The energetic structure and dispersion of the conduction bands is captured well by the computational treatment, with some quantitative discrepancies remaining. Our results provide a broader understanding of the electronic structure of SnS2 in particular and van der Waals-layered semiconductors in general. C1 [Racke, David A.; Monti, Oliver L.

We derive a dispersion function that incorporates the polarization function of both the graphene monolayers and the semi-infinite electron liquid at whose surface the electrons scatter specularly. We find a surface plasmon-polariton that is not damped by particle-hole excitations or the bulk modes and which separates below the continuum mini-band of bulk plasmon modes. The surface plasmon frequency of the hybrid structure always lies below omega(s)=p/root 2, the surface plasmon frequency of the conducting substrate. The intensity of this mode depends on the distance of the graphene layers from the conductor's surface, the energy band gap between valence and conduction bands of graphene monolayer and, most importantly, on the number of two-dimensional layers. For a sufficiently large number of layers (N greater than or similar to 7) the hybrid structure has no surface plasmon. The existence of plasmons with different dispersion relations indicates that quasiparticles with different group velocity may coexist for various ranges of wavelengths determined by the number of layers in the superlattice.

With complementary European ERA-Interim reanalysis, National Centers for Environmental Prediction (NCEP) Climate forecast system version 2 (CFSv2) analysis and satellite passive microwave data, we examine the evolution of atmospheric and surface melt conditions in the two differing melt seasons. Prevailing atmospheric conditions contributed to a longer and more continuous melt season in summer 2012 than in 2013, which was corroborated by in situ observations. ERA-Interim reanalysis data showed that longwave radiation likely played a key role in delaying the snowmelt onset in 2013. The earlier melt onset in 2012 reduced the albedo, providing a positive ice-albedo feedback at a time when solar insolation was high. Due to earlier melt onset and later freeze-up in 2012, more solar heat was deposited into the ice-ocean system than in 2013. Summer 2013 was characterized by later melt onset, intermittent freezing events and an earlier fall freeze-up, resulting in considerably fewer effective days of surface melt and a higher average albedo. Calculations for idealized seasonal albedo evolution show that moving the melt onset just 1week earlier in mid-June increases the total absorbed solar radiation by nearly 14% for the summer season. Therefore, the earlier melt onset may have been one of the most important factors driving the more dramatic melt season in 2012 than 2013, though atmospheric circulation patterns, e.g., cyclone in early August 2012, likely contributed as well.

Memory effects are considered to be the result of interactions between a system and its surrounding environment. The analysis leads to the decomposition of a nonlinear system with memory into modes whose temporal behavior is anomalous and lacks a characteristic scale. On average, the time evolution of a mode follows a Mittag-Leffler function, and the system can be described using the fractional calculus. The general theory is demonstrated on the fractional linear harmonic oscillator and the fractional nonlinear logistic equation. When analyzing data from an ill-defined (black-box) system, the spectral decomposition in terms of Mittag-Leffler functions that we propose may uncover inherent memory effects through identification of a small set of dynamically relevant structures that would otherwise be obscured by conventional spectral methods. Consequently, the theoretical concepts we present may be useful for developing more general methods for numerical modeling that are able to determine whether observables of a dynamical system are better represented by memoryless operators, or operators with long-term memory in time, when model details are unknown.

However, artemisinin resistant parasites have recently emerged in South-East Asia. Novel intervention strategies are therefore urgently needed to maintain the current momentum for control and elimination of this disease. In the present study we characterize the phenotypic and genetic properties of the multi drug resistant (MDR) P. falciparum Thai C2A parasite strain in the non-human Aotus primate model, and across multiple passages. Aotus infections with C2A failed to clear upon oral artesunate and mefloquine treatment alone or in combination, and ex vivo drug assays demonstrated reduction in drug susceptibility profiles in later Aotus passages. Further analysis revealed mutations in the pfcrt and pfdhfr loci and increased parasite multiplication rate (PMR) across passages, despite elevated pfmdr1 copy number. Altogether our experiments suggest alterations in parasite population structure and increased fitness during Aotus adaptation. We also present data of early treatment failures with an oral artemisinin combination therapy in a pre-artemisinin resistant P. falciparum Thai isolate in this animal model.

Outbreak years are unpredictable and cases often misdiagnosed. Here we analyzed age-specific data from 2 serological studies (from 1973 and 2012) in Cebu, Philippines, to reconstruct both the annual probability of infection and population-level immunity over a 60-year period (1952-2012). We also explored whether seroconversions during 2012-2013 were spatially clustered. Our models identified 4 discrete outbreaks separated by an average delay of 17 years. On average, 23% (95% confidence interval [CI], 16%-37%) of the susceptible population was infected per outbreak, with >50% of the entire population remaining susceptible at any point. Participants who seroconverted during 2012-2013 were clustered at distances of <230 m, suggesting focal transmission. Large-scale outbreaks of chikungunya did not result in sustained multiyear transmission. Nevertheless, we estimate that >350 000 infections were missed by surveillance systems. Serological studies could supplement surveillance to provide important insights on pathogen circulation.

Sprague-Dawley rats were anesthetized with 1-2% isoflurane/100% oxygen, and their left femoral artery and vein were cannulated. Polytrauma included right femur fracture, and damage to the small intestines, the left and medial liver lobes, and right leg skeletal muscle. Rats were then bled 40% of blood volume. Plasma samples were taken before trauma, and at 30, 60, 120, and 240 min. Polytrauma and hemorrhage led to a significant fall in prothrombin levels. However, circulating thrombin activity did not change significantly over time. Antithrombin III and alpha 2 macroglobulin fell significantly by 2 h, then rose by 4 h. Soluble thrombomodulin was significantly elevated over the 4 h. Circulating plasmin activity, plasminogen, and D-dimers were elevated for the entire 4 h. Tissue plasminogen activator (tPA) was elevated at 30 min, then decreased below baseline levels after 1 h. Plasminogen activator inhibitor-1 was significantly elevated at 2-4 h. Neither tissue factor pathway inhibitor nor thrombin activatable fibrinolysis inhibitor changed significantly over time. The levels of prothrombin and plasminogen were 30-100 times higher than their respective active enzymes. Polytrauma and hemorrhage in rats lead to a fibrinolytic coagulopathy, as demonstrated by an elevation in plasmin activity, D-dimers, and tPA. These results are consistent with the observed clinical benefit of tranexamic acid in trauma patients. C1 US Army Inst Surg Res, Blood Res, Ft Sam Houston, TX 78234 USA.

These measurements reveal the influence of layer thickness on carrier dynamics when probing near the band gap. Furthermore, fluencedependent measurements indicate that carrier relaxation is primarily influenced by surface-related defect and trap states after above-bandgap photoexcitation. The ability to probe femtosecond carrier dynamics in individual flakes can thus give much insight into light-matter interactions in these twodimensional nanosystems.

While most previous work on synthesizing nanocrystalline (NC) metal-matrix nanocomposites (MMNCs) has used cryomilling technique with liquid nitrogen and stearic acid followed by high temperature/high vacuum drying, we employed an advanced room temperature method that involves milling in ethanol followed by low temperature atmospheric drying - a much less expensive process. To understand the strengthening mechanisms of MMNCs, pure NC Al was reinforced with varying concentrations of Al2O3 nanoparticles (NPs) and graphene nanoplatelets (GNPs). The results show that i) room temperature milling in ethanol followed by a relatively low temperature drying treatment can produce NC Al and NC Al MMNCs with grain sizes comparable to materials produced by cryomilling, ii) grain boundary strengthening as described by the Hall-Petch relation accounts for the strength of Al-Al2O3 MMNCs, and iii) grain boundary strengthening and solute strengthening seem to account for the strength in Al-GNP MMNCs.

TI Bacterial vaginosis: a synthesis of the literature on etiology, prevalence, risk factors, and relationship with chlamydia and gonorrhea infections SO MILITARY MEDICAL RESEARCH LA English DT Review DE Bacterial vaginosis; Chlamydia; Gonorrhea; Military; Epidemiology; STI ID SEXUALLY-TRANSMITTED-DISEASES; HAEMOPHILUS-VAGINALIS; GARDNERELLA-VAGINALIS; NONSPECIFIC VAGINITIS; NEISSERIA-GONORRHOEAE; PREGNANT-WOMEN; TRACHOMATIS INFECTIONS; GENITAL-INFECTION; SEX WORKERS; GRAM STAIN AB Bacterial vaginosis (BV) is a common vaginal disorder in women of reproductive age. Since the initial work of Leopoldo in 1953 and Gardner and Dukes in 1955, researchers have not been able to identify the causative etiologic agent of BV. There is increasing evidence, however, that BV occurs when Lactobacillus spp., the predominant species in healthy vaginal flora, are replaced by anaerobic bacteria, such as Gardenella vaginalis, Mobiluncus curtisii, M. mulieris, other anaerobic bacteria and/or Mycoplasma hominis. Worldwide, it estimated that 20-30 % of women of reproductive age attending sexually transmitted infection (STI) clinics suffer from BV, and that its prevalence can be as high as 50-60 % in high-risk populations (e.g., those who practice commercial sex work (CSW). Epidemiological data show that women are more likely to report BV if they: 1) have had a higher number of lifetime sexual partners; 2) are unmarried; 3) have engaged in their first intercourse at a younger age; 4) have engaged in CSW, and 5) practice regular douching. In the past decade, several studies have provided evidence on the contribution of sexual activity to BV. However, it is difficult to state that BV is a STI without being able to identify the etiologic agent. BV has also emerged as a public health problem due to its association with other STIs, including: human immunodeficiency virus (HIV), herpes simplex virus type 2 (HSV-2), Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG). The most recent evidence on the association between BV and CT/NG infection comes from two secondary analyses of cohort data conducted among women attending STI clinics. Based on these studies, women with BV had a 1.8 and 1.9-fold increased risk for NG and CT infection, respectively. Taken together, BV is likely a risk factor or at least an important contributor to subsequent NG or CT infection in high-risk women. Additional research is required to determine whether this association is also present in other low-risk sexually active populations, such as among women in the US military. It is essential to conduct large scale cross-sectional or population-based case-control studies to investigate the role of BV as a risk factor for CT/NG infections. These studies could lead to the development of interventions aimed at reducing the burden associated with bacterial STIs worldwide.

Rats orally exposed to NTO have demonstrated testicular toxicity in both subacute and subchronic studies; however, toxicity has not been verified in mice. Also, previous studies have not demonstrated the nature of NTO-induced testicular toxicity due to the prolonged dosing regimen utilized and effects of maturation depletion. In this study, a time-course design was used and the earliest pathological changes in testes of adult BALB/c mice orally dosed with NTO in corn oil suspensions at 0, 500 or 1000mg/kg-day NTO for 1, 3, 7 or 14 d were evaluated. The earliest NTO-induced testicular changes occurred in the 1000mg/kg-day group at day 7 and the 500mg/kg-day group at day 14 as evident by the presence of bi- and multinucleated giant cells (MNGCs) of almost all spermatids in an isolated stage II-III tubule/step 2-3 and a stage IX tubule/step 9 in the 1000 and 500mg/kg-day groups, respectively. Testicular toxicity was characterized by degeneration and the presence of bi- and MNGCs of spermatids (stages II-III and IX), which progressed to additional germ cell degeneration as dosing duration increased. Occasional step 16 spermatid retention was also noted in stage XII and I tubules in the day 14, 1000mg/kg-day group. These data indicate that NTO is a testicular toxicant in mice and that spermatids are the most sensitive cell. The presence of retained spermatids warrants further investigation regarding NTO's role as a direct Sertoli cell toxicant.

While there are many tools at a physician's disposal to monitor patients in a hospital setting, the reality is that none of these tools allow hi-fidelity assessment or continuous monitoring towards early detection of hemodynamic instability. We present an advanced automated analytical system which would act as a continuous monitoring and early warning mechanism that can indicate pending decompensation before traditional metrics can identify any clinical abnormality. This system computes novel features or bio-markers from both heart rate variability (HRV) as well as the morphology of the electrocardiogram (ECG). To compare their effectiveness, these features are compared with the standard HRV based bio-markers which are commonly used for hemodynamic assessment. This study utilized a unique database containing ECG waveforms from healthy volunteer subjects who underwent simulated hypovolemia under controlled experimental settings. A support vector machine was utilized to develop a model which predicts the stability or instability of the subjects. Results showed that the proposed novel set of features outperforms the traditional HRV features in predicting hemodynamic instability.

The aim of this study was to produce CNF-polyethylene (PE) nanocomposites by melt compounding followed by injection molding to investigate the possibility of using polyvinyl alcohol (PVA) to improve the dispersion of CNF in the PE matrix. The tensile strength of CNF- filled composites was 17.4 MPa with the addition of 5 wt % CNF-PVA, which was 25% higher than the strength of neat PE. The tensile modulus of elasticity increased by 40% with 5% CNF-PVA addition. Flexural properties also significantly increased with increased CNF loading. Shear viscosity increased with increasing CNF content. The elastic moduli of the PE/CNF composites from rheological measurements were greater than those of the neat PE matrix because of the intrinsic rigidity of CNF. Melt creep compliance decreased by about 13% and 45% for the composites with 5 wt % CNF and 10 wt % CNF, respectively. It is expected that the PVA carrier system can contribute to the development of a process methodology to effectively disperse CNFs containing water in a polymer matrix.

Given the system goal states of attackers and defenders, we study what strategies attackers or defenders can take to reach their respective system goal state (i.e., winning system state) with minimum resource consumption. However, due to the dynamics of a network caused by a node's mobility, failure or its resource depletion over time or action(s), this optimization problem becomes NP-complete. We propose two heuristic strategies in a greedy manner based on a node's two characteristics: resource level and influence based on k-hop reachability. We analyze complexity and optimality of each algorithm compared to optimal solutions for a small-scale static network. Further, we conduct a comprehensive experimental study for a large-scale temporal network to investigate best strategies, given a different environmental setting of network temporality and density. We demonstrate the performance of each strategy under various scenarios of attacker/defender strategies in terms of win probability, resource consumption, and system vulnerability.

The aim of this study was to analyse changes in the genetic diversity of P. vivax genes from field isolates collected at different times along the Thai-Myanmar border. Methods: Two hundred and fifty-four P. vivax isolates collected during two periods 10 years apart along the Thai-Myanmar border were analysed. The parasites were genotyped by nested-PCR and PCR-RFLP targeting selected polymorphic loci of Pvmsp1, Pvmsp3a and Pvcsp genes. Results: The total number of distinguishable allelic variants observed for Pvcsp, Pvmsp1, and Pvmsp3a was 17, 7 and 3, respectively. High genetic diversity was observed for Pvcsp (H-E = 0.846) and Pvmsp1 (H-E = 0.709). Of the 254 isolates, 4.3 and 14.6 % harboured mixed Pvmsp1 and Pvcsp genotypes with a mean multiplicity of infection (MOI) of 1.06 and 1.15, respectively. The overall frequency of multiple genotypes was 16.9 %. When the frequencies of allelic variants of each gene during the two distinct periods were analysed, significant differences were noted for Pvmsp1 (P = 0.018) and the Pvcsp (P = 0.033) allelic variants. Conclusion: Despite the low malaria transmission levels in Thailand, P. vivax population exhibit a relatively high degree of genetic diversity along the Thai-Myanmar border of Thailand, in particular for Pvmsp1 and Pvcsp, with indication of geographic and temporal variation in frequencies for some variants. These results are of relevance to monitoring the emergence of drug resistance and to the elaboration of measures to control vivax malaria.

Here we antigenically and genetically characterized 93 AIV isolates from North America (85 from migratory waterfowl [1976-2010], 7 from domestic poultry [1971-2012], and 1 from a seal [1980]). The hemagglutinin gene of these H7 viruses are separated from those from Eurasia. Gradual accumulation of nucleotide and amino acid substitutions was observed in the hemagglutinin of H7 AIVs from waterfowl and domestic poultry. Genotype characterization suggested that H7 AIVs in wild birds form diverse and transient internal gene constellations. Serologic analyses showed that the 93 isolates cross-reacted with each other to different extents. Antigenic cartography showed that the average antigenic distance among them was 1.14 units (standard deviation [SD], 0.57 unit) and that antigenic diversity among the H7 isolates we tested was limited. Our results suggest that the continuous genetic evolution has not led to significant antigenic diversity for H7 AIVs from North America. These findings add to our understanding of the natural history of IAVs and will inform public health decision-making regarding the threat these viruses pose to humans and poultry.

Twenty-eight male, active duty soldiers walked on an instrumented treadmill while external force data and kinematics were recorded. A rigid body model was used to estimate joint moments and reaction forces. A musculoskeletal model was used to gather muscle length, muscle velocity, moment arm and orientation information. Optimization procedures were used to estimate muscle forces and finally internal bone forces and moments were applied to an inhomogeneous, subject specific bone model obtained from CT scans to estimate stress in the bone cross section. Validity was assessed by comparison to stresses calculated from strain gage data in the literature and sensitivity was investigated using two simplified versions of the bone model-a homogeneous model and an ellipse approximation. Peak compressive stress occurred on the posterior aspect of the cross section ( -47.5 +/- 14.9 MPa). Peak tensile stress occurred on the anterior aspect (27.0 +/- 11.7 MPa) while the location of peak shear was variable between subjects (7.2 +/- 2.4 MPa). Peak compressive, tensile and shear stresses were within 0.52 MPa, 0.36 MPa and 3.02 MPa respectively of those calculated from the converted strain gage data. Peak values from a inhomogeneous model of the bone correlated well with homogeneous model (normal: 0.99; shear: 0.94) as did the normal ellipse model (r=0.89-0.96). However, the relationship between shear stress in the inhomogeneous model and ellipse model was less accurate (r=0.64). The procedures detailed in this paper provide a non-invasive and relatively quick method of estimating cross sectional stress that holds promise for assessing injury and osteogenic stimulus in bone during normal physical activity.

Using an expanded deformation potential approach, we present a theoretical study of the electron-phonon self-energy and scattering matrix elements across the entire Brillouin zone. We elucidate the roles of modulated hopping and conventional deformation potential coupling, parameterized via standard deformation potentials, the in-plane phonon modes, intra- and interband contributions, and umklapp processes. Applying the theory to nonlinear optical transmission spectroscopy in the vicinity of the M point, we find very good agreement with recently published experimental data.

In this paper, surface buckling and its effect on its electronic properties are investigated by using molecular dynamics simulations together with density functional theory calculations. We find that phosphorene shows superior structural flexibility along the armchair direction allowing it to have large curvatures. The semiconducting and direct band gap nature are retained with buckling along the armchair direction; the band gap decreases and transforms to an indirect band gap with buckling along the zigzag direction. The structural flexibility and electronic robustness along the armchair direction facilitate the fabrication of devices with complex shapes, such as folded phosphorene and phosphorene nano-scrolls, thereby offering new possibilities for the application of phosphorene in flexible electronics and optoelectronics.

In this work, those issues are significantly relieved by entrapping sulfur species in carbon host rich in oxygen functionalities. Sulfur species in such C/S composite are highly stabilized by their interaction with oxygen, and can deliver a reversible capacity of 508 mAh/(g of S) for 2000 cycles when coupled with Li, representing the best cycling stability up to date. More interestingly, extra capacity can be accessed by simply prelithiating the oxygen-stabilized C/S composites down to 0.6 V for a few cycles, which enables a high capacity of 1621 mAh/(g of S) that eventually stabilizes at 820 mAh/(g of S) for 600 cycles. The mechanism for this electrochemical activation process is investigated with both spectroscopic and electrochemical techniques, which reveal that the inactive sulfur bonded to oxygen is liberated in the initial deep lithiation precycles and becomes electrochemically active. The oxygen-stabilized sulfur can also be coupled with Na anode to form Na/S cell, confirming that the formation of S-O interaction in C/S composite generates promising sulfur-based cathode materials for Li-S and Na-S batteries.

Its increasing detection during Ostreopsis blooms and in seafood highlights the need to characterize its toxic effects and to set up appropriate detection methods. OVTX-a is about 100 fold less potent than PLTX in reducing HaCaT cells viability (EC50 = 1.1 X 10(-9) M vs 1.8 X 10(-11) M, MTT test) in agreement with a reduced binding affinity (Kd = 1.2 X 10(-9) vs 2.7 X 10(-11) M, saturation experiments on intact cells). Similarly, OVTX-a hemolytic effect is lower than that of the reference PLTX compound. OstD shows the lowest cytotoxicity toward HaCaT keratinocytes, suggesting the lack of a hydroxyl group at C44 as a critical feature for PLTXs cytotoxic effects. A sandwich ELISA developed for PLTX detects also OVTX-a in a sensitive (LOD = 4.2 and LOQ = 5.6 ng/mL) and accurate manner (Bias = 0.3%), also in 0. cf. ovata extracts and contaminated mussels. Although in vitro OVTXa appears less toxic than PLTX, its cytotoxicity at nanomolar concentrations after short exposure time rises some concern for human health. The sandwich ELISA can be a viable screening method for OVTXs detection in monitoring program.

These protein toxins bind directly to specific V beta regions of T-cell receptors (TCR) and major histocompatibility complex (MHC) class II on antigen-presenting cells, resulting in hyperactivation of T lymphocytes and monocytes/macrophages. Activated host cells produce excessive amounts of proinflammatory cytokines and chemokines, especially tumor necrosis factor alpha, interleukin 1 (IL-1), IL-2, interferon gamma (IFN gamma), and macrophage chemoattractant protein 1 causing clinical symptoms of fever, hypotension, and shock. Because of superantigen-induced T cells skewed toward TH1 helper cells, and the induction of proinflammatory cytokines, superantigens can exacerbate autoimmune diseases. Upon TCR/MHC ligation, pathways induced by superantigens include the mitogen-activated protein kinase cascades and cytokine receptor signaling, resulting in activation of NF kappa B and the phosphoinositide 3-kinase/mammalian target of rapamycin pathways. Various mouse models exist to study SEB-induced shock including those with potentiating agents, transgenic mice and an "SEB-only" model. However, therapeutics to treat toxic shock remain elusive as host response genes central to pathogenesis of superantigens have only been identified recently. Gene profiling of a murine model for SEB-induced shock reveals novel molecules upregulated in multiple organs not previously associated with SEB-induced responses. The pivotal genes include intracellular DNA/RNA sensors, apoptosis/DNA damage-related molecules, immunoproteasome components, as well as antiviral and IFN-stimulated genes. The host-wide induction of these, and other, antimicrobial defense genes provide evidence that SEB elicits danger signals resulting in multi-organ damage and toxic shock. Ultimately, these discoveries might lead to novel therapeutics for various superantigen-based diseases.

Nicolaus, Marcel TI Geometric Effects of an Inhomogeneous Sea Ice Cover on the under Ice Light Field SO Frontiers in Earth Science LA English DT Article DE optics; irradiance; inherent optical properties; spatial variability; extinction coefficient ID TRANSMISSION; OCEAN; MELT AB Light measurements in the ocean provide crucial information about the energy fluxes in the climate and ecosystem. Currently radiative transfer problems are usually considered in horizontally homogeneous layers although it is known to be a crude assumption in many cases. In this paper, we examine the effects of a horizontally inhomogeneous sea ice layer on the light field in the water underneath. We implemented a three dimensional model, capable to simulate the light field underneath arbitrary surface geometries using ray optics. The results show clear effects of the measurement geometry on measured fluxes obtained with different sensor types, which need to be taken into account for the correct interpretation of the data. Radiance sensors are able to better sense the spatial variability of ice optical properties as compared to irradiance sensors. Furthermore, we show that the determination of the light extinction coefficient of water from vertical profiles is complicated under a horizontally inhomogeneous ice cover. This uncertainty in optical properties of the water, as well as the measurement geometry also limits the possibility to correct light measurements taken at depth for the influence of water in between the sea ice and the sensor.

TI Effect of sulfates on passivation in alkaline environments SO PROCEEDINGS OF THE INSTITUTION OF CIVIL ENGINEERS-CONSTRUCTION MATERIALS LA English DT Article DE concrete technology & manufacture; corrosion; materials technology ID SIMULATED PORE SOLUTIONS; STAINLESS-STEELS; CORROSION-RESISTANCE; BEHAVIOR AB Studies investigating passivation behaviour and corrosion resistance in simulated alkaline environments have typically been conducted in solutions containing sodium hydroxide (NaOH), potassium hydroxide (KOH) and calcium hydroxide (Ca(OH)(2)), with limited study of the effect of sulfates (SO42-). These sulfates are known to be present in the pore solution of materials like Portland cement-based concrete and may also ingress by the exposure to sulfate-rich environments. This study investigates the passivation behaviour and potentiodynamic polarisation behaviour of a high-strength carbon steel and high-strength stainless steels (austenitic and duplex) in saturated calcium hydroxide solutions containing up to 2000 ppm SO42-. Results indicate a negligible impact on the passivation behaviours of single-phase carbon steel and austenitic stainless steels. However, in duplex stainless steels, 1000 ppm of SO42- promotes passivation, whereas higher concentrations of 2000 ppm inhibit passivation. Additional research is necessary to correlate the altered passivation behaviour resulting from the presence of SO42- with chloride-induced corrosion resistance.

TI Variability in integration of mechanisms associated with high tolerance to progressive reductions in central blood volume: the compensatory reserve SO PHYSIOLOGICAL REPORTS LA English DT Article DE Presyncope; hypovolemia; hemorrhage; compensatory reserve ID BODY NEGATIVE-PRESSURE; HEART-RATE-VARIABILITY; CENTRAL HYPOVOLEMIA; ARTERIAL-PRESSURE; BAROREFLEX; TRAUMA; EPIDEMIOLOGY; OSCILLATIONS; SENSITIVITY; INFARCTION AB High tolerance to progressive reductions in central blood volume has been associated with higher heart rate (HR), peripheral vascular resistance (PVR), sympathetic nerve activity (SNA), and vagally mediated cardiac baroreflex sensitivity (BRS). Using a database of 116 subjects classified as high tolerance to presyncopal-limited lower body negative pressure (LBNP), we tested the hypothesis that subjects with greater cardiac baroreflex withdrawal (i.e., BRS > 1.0) would demonstrate greater LBNP tolerance associated with higher HR, PVR, and SNA. Subjects underwent LBNP to presyncope. Mean and diastolic arterial pressure (MAP; DAP) was measured by finger photoplethysmography and BRS (down sequence) was autocalculated (WinCPRS) as Delta R-R Interval/Delta DAP. Down(BRS) (ms/mmHg) was used to dichotomize subjects into two groups (Group 1 = Down(BRS) > 1.0, N = 49, and Group 2 = Down(BRS) < 1.0, N = 67) at the time of presyncope. Muscle SNA was measured directly from the peroneal nerve via microneurography (N = 19) in subjects from Groups 1 (n = 9) and 2 (n = 10). Group 1 (Down(BRS) > 1.0) had lower HR (107 +/- 19 vs. 131 +/- 20 bpm), higher stroke volume (45 +/- 15 vs. 36 +/- 15 mL), less SNA (45 +/- 13 vs. 53 +/- 7 bursts/min), and less increase in PVR (4.1 +/- 1.3 vs. 4.5 +/- 2.6) compared to Group 2 (Down(BRS) < 1.0). Both groups had similar tolerance times (1849 +/- 260 vs. 1839 +/- 253 sec), MAP (78 +/- 11 vs. 79 +/- 12 mmHg), compensatory reserve index (CRI) (0.10 +/- 0.03 vs. 0.09 +/- 0.01), and cardiac output (4.5 +/- 1.2 vs. 4.7 +/- 1.1 L/min) at presyncope. Contrary to our hypothesis, higher HR, PVR, SNA, and BRS were not associated with greater tolerance to reduced central blood volume. These data are the first to demonstrate the variability and uniqueness of individual human physiological strategies designed to compensate for progressive reductions in central blood volume. The sum total of these integrated strategies is accurately reflected by the measurement of the compensatory reserve.

We discuss the role of early phase clinical trials, including pharmacokinetic-pharmacodynamic (PK-PD) trials, and the value of including both placebo and active standards of comparison in acute pain trials. This article focuses on single-dose and short-duration trials with emphasis on the perioperative and study design factors that influence assay sensitivity. Recommendations are presented on assessment measures, study designs, and operational factors. Although most of the methodological advances have come from studies of postoperative pain after dental impaction, bunionectomy, and other surgeries, the design considerations discussed are applicable to many other acute pain studies conducted in different settings.

TI Production of Mucosally Transmissible SHIV Challenge Stocks from HIV-1 Circulating Recombinant Form 01_AE env Sequences SO PLOS PATHOGENS LA English DT Article ID VACCINE EFFICACY TRIAL; RHESUS-MONKEYS; VIRUS; NEUTRALIZATION; INDUCTION; INFECTION; ASSAY; TIME AB Simian-human immunodeficiency virus (SHIV) challenge stocks are critical for preclinical testing of vaccines, antibodies, and other interventions aimed to prevent HIV-1. A major unmet need for the field has been the lack of a SHIV challenge stock expressing circulating recombinant form 01_AE (CRF01_AE) env sequences. We therefore sought to develop mucosally transmissible SHIV challenge stocks containing HIV-1 CRF01_AE env derived from acutely HIV-1 infected individuals from Thailand. SHIV-AE6, SHIV-AE6RM, and SHIV-AE16 contained env sequences that were >99% identical to the original HIV-1 isolate and did not require in vivo passaging. These viruses exhibited CCR5 tropism and displayed a tier 2 neutralization phenotype. These challenge stocks efficiently infected rhesus monkeys by the intrarectal route, replicated to high levels during acute infection, and established chronic viremia in a subset of animals. SHIV-AE16 was titrated for use in single, high dose as well as repetitive, low dose intrarectal challenge studies. These SHIV challenge stocks should facilitate the preclinical evaluation of vaccines, monoclonal antibodies, and other interventions targeted at preventing HIV-1 CRF01_AE infection.

Differences in perceived barriers to care by type of help used were also assessed. Methods: Active-duty soldiers from four brigade combat teams (N=3,380) were surveyed in 2008-2009. Items assessed posttraumatic stress disorder; depression; anxiety; help needed because of a stress, emotional, alcohol, or family problem; stigma; negative attitudes toward care; and organizational barriers. Participants reported receipt of help in the past three months from providers (mental health or medical professionals or an Army resource hotline) or nonproviders (fellow soldier, medic, chaplain, or chain of command). Results: Nearly a third (31%) were identified as being in need of mental health care. Of those, 5% reported using nonprovider help exclusively, 14% used provider help exclusively, and 7% used both types. Stigma was rated significantly lower as a barrier among those who used help exclusively from providers than among those who did not use help from any source; however, no significant differences in stigma scores were found between those who used help from nonproviders and those who did not use help from any source. Soldiers who used help from nonproviders were more likely than those who used help from providers to perceive organizational barriers. Conclusions: Results show that soldiers may view nonproviders as alternative sources of mental health help, suggesting that the Army should ensure that such resources are adequately trained and integrated into the mental health community so that soldiers can receive the help they need.

TI On the formation of Friedlander waves in a compressed-gas-driven shock tube SO PROCEEDINGS OF THE ROYAL SOCIETY A-MATHEMATICAL PHYSICAL AND ENGINEERING SCIENCES LA English DT Article DE blast waves; shock tubes; Friedlander waves ID TRAUMATIC BRAIN-INJURY; BLAST; MODELS AB Compressed-gas-driven shock tubes have become popular as a laboratory-scale replacement for field blast tests. The well-known initial structure of the Riemann problem eventually evolves into a shock structure thought to resemble a Friedlander wave, although this remains to be demonstrated theoretically. In this paper, we develop a semi-analytical model to predict the key characteristics of pseudo blast waves forming in a shock tube: location where the wave first forms, peak over-pressure, decay time and impulse. The approach is based on combining the solutions of the two different types of wave interactions that arise in the shock tube after the family of rarefaction waves in the Riemann solution interacts with the closed end of the tube. The results of the analytical model are verified against numerical simulations obtained with a finite volume method. The model furnishes a rational approach to relate shock tube parameters to desired blast wave characteristics, and thus constitutes a useful tool for the design of shock tubes for blast testing.

To address these disparities in access to care, we propose streamlining graduate medical education to increase efficiency and enhance cost-effectiveness while simultaneously increasing the number ofpsychiatric subspecialists in these key areas. We propose that trainees interested in subspecialties complete their general training in 3 years, while meeting ACGME required milestones, and then utilize their 4th year to complete subspecialty fellowship training. Eligible trainees would then qualify' for psychiatry subspecialty certification and general psychiatry ABPN certification at the end of 4 years.

Both sides of these sensory benefits have long been appreciated, yet less is known of how the perception of events from the perspectives of both prey and predator can interact to influence their encounters. Here we examined how a visual sensory mechanism impacts the collective motion of prey and, subsequently, how their resulting movements influenced predator confusion and capture ability. We presented virtual prey to human players in a targeting game and measured the speed and accuracy with which participants caught designated prey. As prey paid more attention to neighbor movements their collective coordination increased, yet increases in prey coordination were positively associated with increases in the speed and accuracy of attacks. However, while attack speed was unaffected by the initial state of the prey, accuracy dropped significantly if the prey were already organized at the start of the attack, rather than in the process of self-organizing. By repeating attack scenarios and masking the targeted prey's neighbors we were able to visually isolate them and conclusively demonstrate how visual confusion impacted capture ability. Delays in capture caused by decreased coordination amongst the prey depended upon the collection motion of neighboring prey, while it was primarily the motion of the targets themselves that determined capture accuracy. Interestingly, while a complete loss of coordination in the prey (e.g., a flash expansion) caused the greatest delay in capture, such behavior had little effect on capture accuracy. Lastly, while increases in collective coordination in prey enhanced personal risk, traveling in coordinated groups was still better than appearing alone. These findings demonstrate a trade-off between the sensory mechanisms that can enhance the collective properties that emerge in social animals and the individual group member's predation risk during an attack.

Efforts are being made to reprogram, maintain, and differentiate iPSCs in defined conditions to provide a safe source of stem cells for regenerative medicine. Recently, human fibroblasts were successfully reprogrammed into pluripotent stem cells using four recombinant proteins (OCT4, c-Myc, KLF4, and SOX2) fused with a cell-penetrating peptide (9R). These protein-induced pluripotent stem cells (piPSCs) are maintained and propagated on a feeder layer of mouse embryonic fibroblasts. Use of animal-derived products in maintenance and differentiation of iPSCs poses risks of zoonotic disease transmission and immune rejection when transplanted into humans. To avoid potential incorporation of xenogenic products, we cultured piPSCs on recombinant human matrix proteins. We then tested whether recombinant human matrix proteins can support self-renewal and pluripotency of piPSCs. After long-term culture on recombinant human vitronectin in xeno-free conditions, piPSCs retained the expression of pluripotent markers. The pluripotency of these cells was further evaluated by differentiating toward ectoderm, mesoderm, and endoderm lineages in vitro. In conclusion, recombinant human vitronectin can support the long-term culture and maintain the stemness of piPSCs in defined nonxenogenic conditions.

The challenge focused on the adsorption of perfluorohexane in the activated carbon standard BAM-P109. Entrants were challenged to predict the adsorption of perfluorohexane in the activated carbon at a temperature of 273K and at relative pressures of 0.1, 0.3, and 0.6. The relative pressure (P/P-o) is defined as that relative to the bulk saturation pressure predicted by the fluid model at a given temperature (273K in this case). The predictions were judged by comparison to a set of experimentally determined values, which are published here for the first time and were not disclosed to the entrants prior to the challenge. Benchmark experimental studies, described herein, were also carried out and provided to entrants in order to aid in the development of new force fields and simulation methods to be employed in the challenge. These studies included argon, carbon dioxide, and water adsorption in the BAM-P109 activated carbon as well as X-ray diffraction, X-ray microtomography, photoelectron spectroscopy, and atomic emission spectroscopy studies of BAM-P109. Several concurrent studies were carried out for the BAM-P108 activated carbon. These are included in the current manuscript for comparison.

TI Stress-dependent ultrasonic scattering in polycrystalline materials SO JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA LA English DT Article ID RESIDUAL-STRESSES; WAVE PROPAGATION; ACOUSTOELASTICITY; BACKSCATTER; ALUMINUM; TEXTURE; MICROSTRUCTURE; DEFORMATION; ATTENUATION; CRYSTALS AB Stress-dependent elastic moduli of polycrystalline materials are used in a statistically based model for the scattering of ultrasonic waves from randomly oriented grains that are members of a stressed polycrystal. The stress is assumed to be homogeneous and can be either residual or generated from external loads. The stress-dependent elastic properties are incorporated into the definition of the differential scattering cross-section, which defines how strongly an incident wave is scattered into various directions. Nine stress-dependent differential scattering cross-sections or scattering coefficients are defined to include all possibilities of incident and scattered waves, which can be either longitudinal or (two) transverse wave types. The evaluation of the scattering coefficients considers polycrystalline aluminum that is uniaxially stressed. An analysis of the influence of incident wave propagation direction, scattering direction, frequency, and grain size on the stress-dependency of the scattering coefficients follows. Scattering coefficients for aluminum indicate that ultrasonic scattering is much more sensitive to a uniaxial stress than ultrasonic phase velocities. By developing the stress-dependent scattering properties of polycrystals, the influence of acoustoelasticity on the amplitudes of waves propagating in stressed polycrystalline materials can be better understood. This work supports the ongoing development of a technique for monitoring and measuring stresses in metallic materials. (C) 2016 Acoustical Society of America.

Maternal antibodies in each of these four categories were detected in cord blood and decreased to their lowest level by approximately 6 months of age. Serologic antibodies to 3 preerythrocytic and 10 blood-stage antigens subsequently increased, reaching peak prevalence by 36 months. In contrast, antibodies measured by VSA, GIA, and IIA remained low even up to 36 months. Infants sensitized to P. falciparum in utero, defined by cord blood lymphocyte recall responses to malaria antigens, acquired antimalarial antibodies at the same rate as those who were not sensitized in utero, indicating that fetal exposure to malaria antigens did not affect subsequent infant antimalarial responses. Infants with detectable serologic antibodies at 12 months of age had an increased risk of P. falciparum infection during the subsequent 24 months. We conclude that serologic measures of antimalarial antibodies in children 36 months of age or younger represent biomarkers of malaria exposure rather than protection and that functional antibodies develop after 36 months of age in this population.

Analysis of rater assessment reliability included both total score agreement and agreement across individual push-up repetitions. This study utilized 8 Raters who assessed 15 different videotaped push-up performances over 4 iterations separated by a minimum of 1 week. The 15 push-up participants were videotaped during the semiannual Army Physical Fitness Test. Each Rater randomly viewed the 15 push-up and verbally responded with a "yes" or "no" to each push-up repetition. The data generated were analyzed using the Pearson product-moment correlation as well as the kappa, modified kappa and the intra-class correlation coefficient (3,1). An attribute agreement analysis was conducted to determine the percent of inter-rater and intra-rater agreement across individual push-ups. The results indicated that Raters varied a great deal in assessing push-ups. Over the 4 trials of 15 participants, the overall scores of the Raters varied between 3.0 and 35.7 push-ups. Post hoc comparisons found that there was significant increase in the grand mean of push-ups from trials 1-3 to trial 4 (p < 0.05). Also, there was a significant difference among raters over the 4 trials (p < 0.05). Pearson correlation coefficients for inter-rater and intra-rater reliability identified inter-rater reliability coefficients were between 0.10 and 0.97. Intra-rater coefficients were between 0.48 and 0.99. Intra-rater agreement for individual push-up repetitions ranged from 41.8% to 84.8%. The results indicated that the raters failed to assess the same push-up repetition with the same score (below 70% agreement) as well as failed to agree when viewed between raters (29%). Interestingly, as previously mentioned, scores on trial 4 increased significantly which might have been caused by rater drift or that the Raters did not maintain the push-up standard over the trials. It does appear that the final push-up scores received by each participant was a close approximation of actual performance (within 65%) but when assessing physical performance for retention in the Army, a more reliable test might be considered.

Loss in physical readiness may be a function of age and the operational demands associated with increasing years of service. The purpose of this study was to assess strength and physiological characteristics in different cohorts of U.S. Army Soldiers based on years of service and age. A total of 253 Soldiers (age: 28.1 +/- 6.8 years; height: 1.76 +/- 0.11 m; mass: 84.1 +/- 12.2 kg) participated. Individual subject cohorts were created based on years of service (1-5 years, 6-10 years, 11-15 years) and age (20-24 years, 25-29 years, 30-34 years, 35-39 years, 40-44 years). Testing included shoulder, knee, ankle, and torso strength, aerobic capacity/lactate threshold, anaerobic power/capacity, and body composition/total mass. Those with 11 to 15 years of service and between ages 30 and 34 had a higher percentage of body fat, and lower aerobic capacity and lactate threshold than younger Soldiers with fewer years of service. Physical training interventions should focus on maintenance of physiological characteristics to offset the loss of readiness at the similar time point of 11 to 15 years of service and 30 to 34 years of age.

We examine and compare the communication efficiency of transcriptional networks extracted from the bacterium Escherichia coli and the baker's yeast Saccharomyces cerevisiae using discrete event simulation based in silico experiments. The packet receipt rate is used as a dynamical metric to understand information flow, while unsupervised machine learning techniques are used to examine underlying relationships inherent to the network topology. To this effect, we defined sixteen features based on structural/topological significance, such as transcriptional motifs, and other traditional metrics, such as network density and average shortest path, among others. Support vector classification is used with these features after parameters were identified using a cross-validation grid-search method. Feature ranking is performed using analysis of variance F-value metric. We found that feed-forward loop (FFL) based features consistently show up as significant in both the bacterial and yeast networks, even at different noise levels. We then use a supervised machine learning technique (random forests) to investigate the structural prominence of the FFL motif in information transmission using subnetworks (larger sample size compared to the unsupervised approach) extracted from Escherichia coli transcriptional regulatory network. Further, we study the role of FFLs in signal transduction within the complete Escherichia coli regulatory network. Although our work reveals a minimal role of FFLs in signal transduction, it highlights the structural role of FFLs in information transmission captured by random forest regression. This work paves the way to design specialized engineered systems, such as wireless sensor networks, that exploit topological properties of natural networks to attain maximum efficiency.

A list of hydrophytes and their wetland indicator rating is published by the U.S. Army Corps of Engineers as the National Wetland Plant List (NWPL) and is the basis for assessing the vegetation criteria of Federal wetland delineation manuals. Ratings are primarily based on expert opinion and few empirical studies have been done, particularly at landscape scales. In this study, we developed an approach for quantifying plant indicator ratings at broad spatial scales and used it to estimate the frequency that Picea pungens Engelm. (Colorado blue spruce) occurs in wetlands across a 22,921 km(2) study area in the southern Rocky Mountains. Species distribution models were developed and used to inform a multistage field sampling design. Wetland soil and hydrology indicators were assessed around 423 randomly selected trees in 22 HUC12 watersheds. Only 16.5 % of trees occurred in wetlands, suggesting that a rating of facultative upland (FACU) is more appropriate than the currently published rating of facultative (FAC) for our study area. This study demonstrates that it is feasible to quantitatively evaluate ratings for species even at broad landscape scales.

We infected rhesus macaques orally and also treated them orally with a small and non-absorbable polypropyletherimine dendrimer glucosamine that is a Toll-like receptor-4 (TLR4) antagonist. Antibiotics were not given for this life-threatening infection. Six days later, the clinical score for diarrhoea, mucus and blood was 54% lower, colon interleukin-8 and interleukin-6 were both 77% lower, and colon neutrophil infiltration was 75% less. Strikingly, vasculitis did not occur and tissue fibrin thrombi were reduced by 67%. There was no clinical toxicity or adverse effect of dendrimer glucosamine on systemic immunity. This is the first report in non-human primates of the therapeutic efficacy of a small and orally bioavailable TLR antagonist in severe infection. Our results show that an oral TLR4 antagonist can enable controlled resolution of the infection-related-inflammatory response and can also prevent neutrophil-mediated gut wall necrosis in severe infectious diarrhoeas.

TI Phase 1/2a Trial of Plasmodium vivax Malaria Vaccine Candidate VMP001/AS01(B) in Malaria-Naive Adults: Safety, Immunogenicity, and Efficacy SO PLOS NEGLECTED TROPICAL DISEASES LA English DT Article ID CIRCUMSPOROZOITE PROTEIN; SPOROZOITES; RTS,S/AS02A; VOLUNTEERS; ANTIBODIES; PRIMAQUINE AB Background A vaccine to prevent infection and disease caused by Plasmodium vivax is needed both to reduce the morbidity caused by this parasite and as a key component in efforts to eradicate malaria worldwide. Vivax malaria protein 1 (VMP001), a novel chimeric protein that incorporates the amino-and carboxy-terminal regions of the circumsporozoite protein (CSP) and a truncated repeat region that contains repeat sequences from both the VK210 (type 1) and the VK247 (type 2) parasites, was developed as a vaccine candidate for global use. Methods We conducted a first-in-human Phase 1 dose escalation vaccine study with controlled human malaria infection (CHMI) of VMP001 formulated in the GSK Adjuvant System AS01(B). A total of 30 volunteers divided into 3 groups (10 per group) were given 3 intramuscular injections of 15 mu g, 30 mu g, or 60 mu g respectively of VMP001, all formulated in 500 mu L of AS01(B) at each immunization. All vaccinated volunteers participated in a P. vivax CHMI 14 days following the third immunization. Six non-vaccinated subjects served as infectivity controls. Results The vaccine was shown to be well tolerated and immunogenic. All volunteers generated robust humoral and cellular immune responses to the vaccine antigen. Vaccination did not induce sterile protection; however, a small but significant delay in time to parasitemia was seen in 59% of vaccinated subjects compared to the control group. An association was identified between levels of anti-type 1 repeat antibodies and prepatent period. Significance This trial was the first to assess the efficacy of a P. vivax CSP vaccine candidate by CHMI. The association of type 1 repeat-specific antibody responses with delay in the prepatency period suggests that augmenting the immune responses to this domain may improve strain-specific vaccine efficacy. The availability of a P. vivax CHMI model will accelerate the process of P. vivax vaccine development, allowing better selection of candidate vaccines for advancement to field trials.

We sought to determine the incidence of dengue virus (DENV) infection in adults and children in a prospective cohort study in the Philippines where dengue is hyperendemic. Methodology/Principal Findings A prospective cohort of subjects >= 6 months old in Cebu City, Philippines, underwent active community-based surveillance for acute febrile illnesses by weekly contact. Fever history within the prior seven days was evaluated with an acute illness visit followed by 2, 5, and 8-day, and 3-week convalescent visits. Blood was collected at the acute and 3-week visits. Scheduled visits took place at enrolment and 12 months that included blood collections. Acute samples were tested by DENV PCR and acute/convalescent samples by DENV IgM/IgG ELISA to identify symptomatic infections. Enrolment and 12-month samples were tested by DENV hemagglutination inhibition (HAI)assay to identify subclinical infections. Of 1,008 enrolled subjects, 854 completed all study activities at 12 months per-protocol undergoing 868 person-years of surveillance. The incidence of symptomatic and subclinical infections was 1.62 and 7.03 per 100 person-years, respectively. However, in subjects > 15 years old, only one symptomatic infection occurred whereas 27 subclinical infections were identified. DENV HAI seroprevalence increased sharply with age with baseline multitypic HAIs associated with fewer symptomatic infections. Using a catalytic model, the historical infection rate among dengue naive individuals was estimated to be high at 11-22%/year. Conclusions/Significance In this hyperendemic area with high seroprevalence of multitypic DENV HAIs in adults, symptomatic dengue rarely occurred in individuals older than 15 years. Our findings demonstrate that dengue is primarily a pediatric disease in areas with high force of infection. However, the average age of dengue could increase if force of infection decreases over time, as is occurring in some hyperendemic countries such as Thailand.

AVI-7288, a positively charged antisense phosphorodiamidate morpholino oligomer (PMOplus) targeting the viral nucleoprotein gene, was evaluated as a potential therapeutic intervention for MARV infection following delayed treatment of 1, 24, 48, and 96 h post-infection (PI) in a nonhuman primate lethal challenge model. A total of 30 cynomolgus macaques were divided into 5 groups of 6 and infected with 1,830 plaque forming units of MARV subcutaneously. AVI-7288 was administered by bolus infusion daily for 14 days at 15 mg/kg body weight. Survival was the primary endpoint of the study. While none (0 of 6) of the saline group survived, 83-100% of infected monkeys survived when treatment was initiated 1, 24, 48, or 96 h post-infection (PI). The antisense treatment also reduced serum viremia and inflammatory cytokines in all treatment groups compared to vehicle controls. The antibody immune response to virus was preserved and tissue viral antigen was cleared in AVI-7288 treated animals. These data show that AVI-7288 protects NHPs against an otherwise lethal MARV infection when treatment is initiated up to 96 h PI.

Only then do subsequent larger scale formulations proceed to detonation testing, which will be covered in this paper. Recent advances in characterization techniques have led to unparalleled precision in the characterization of early-time evolution of detonations. The new technique of photo-Doppler velocimetry (PDV) for the measurement of detonation pressure and velocity will be shared and compared with traditional fiber-optic detonation velocity and plate-dent calculation of detonation pressure. In particular, the role of aluminum in explosive formulations will be discussed. Recent developments led to the development of explosive formulations that result in reaction of aluminum very early in the detonation product expansion. This enhanced reaction leads to changes in the detonation velocity and pressure due to reaction of the aluminum with oxygen in the expanding gas products.

TI Nonlinear Control of Robotic Manipulators Driven by Pneumatic Artificial Muscles SO IEEE-ASME TRANSACTIONS ON MECHATRONICS LA English DT Article DE Adaptive control; manipulator control; McKibben actuator; neural network control; pneumatic artificial muscle (PAM); robotic manipulator; sliding mode control ID SLIDING-MODE CONTROL; ADAPTIVE-CONTROL; ACTUATORS AB Lightweight, compliant actuators are particularly desirable in safety-conscious robotic systems intended for interaction with humans. Pneumatic artificial muscles (PAMs) exhibit these characteristics and are capable of higher specific work than comparably sized hydraulic actuators and electric motors. However, control of PAM-actuated systems has proven difficult due to the highly nonlinear nature of the actuators and the pneumatic systems driving their actuation. This study develops and investigates the performance of three advanced control strategies-sliding mode control, adaptive sliding mode control, and adaptive neural network (ANN) control-each containing a distinct level of a priori model knowledge, to enable smooth and accurate motion tracking of a single degree-of-freedom PAM-actuated manipulator. Originally developed by J.-J. Slotine and R.M. Sanner, the specific controllers employed in this study are significantly modified for application to pneumatically actuated open-chain manipulators with complex nonlinear dynamics. The two adaptive controllers are updated online and require no pretraining step. Several experiments are performed with each controller to evaluate and compare closed-loop tracking performance. Results highlight the dependence of a preferred control strategy on the level of model completeness and quality, and suggest that in most PAM-actuated manipulator scenarios, the ANN controller is preferable because it does not require a model of the pneumatic system or joint mechanism design, which can be difficult and time consuming to characterize, and is robust to changes in PAM actuator characteristics (due to fatigue or replacement).

TI Cardiometabolic Health in Submariners Returning from a 3-Month Patrol SO NUTRIENTS LA English DT Article DE adipokines; chemokines; diet; inflammation; insulin resistance; metabolic syndrome; physical activity; obesity ID METABOLIC SYNDROME; INSULIN-RESISTANCE; WEIGHT REGAIN; RISK-FACTORS; MASS INDEX; SHIFT WORK; OBESITY; DISEASE; LEPTIN; FAT AB Confined space, limited exercise equipment, rotating shift work and reduced sleep may affect cardiometabolic health in submariners. To test this hypothesis, 53 male U.S. Submariners (20-39 years) were studied before and after a 3-month routine submarine patrol. Measures included anthropometrics, dietary and physical activity, biomarkers of cardiometabolic health, energy and appetite regulation, and inflammation. Before deployment, 62% of submariners had a body fat % (BF%) 25% (obesity), and of this group, 30% met the criteria for metabolic syndrome. In obese volunteers, insulin, the homeostatic model assessment of insulin resistance (HOMA-IR), leptin, the leptin/adiponectin ratio, and pro-inflammatory chemokines growth-related oncogene and macrophage-derived chemokine were significantly higher compared to non-obese submariners. Following the patrol, a significant mean reduction in body mass (5%) and fat-mass (11%) occurred in the obese group as a result of reduced energy intake (similar to 2000 kJ) during the patrol; and, independent of group, modest improvements in serum lipids and a mean reduction in interferon -induced protein 10 and monocyte chemotactic protein 1 were observed. Since 43% of the submariners remained obese, and 18% continued to meet the criteria for metabolic syndrome following the patrol, the magnitude of weight loss was insufficient to completely abolish metabolic dysfunction. Submergence up to 3-months, however, does not appear to be the cause of obesity, which is similar to that of the general population.

TI Analytically solvable chaotic oscillator based on a first-order filter SO CHAOS LA English DT Article AB A chaotic hybrid dynamical system is introduced and its analytic solution is derived. The system is described as an unstable first order filter subject to occasional switching of a set point according to a feedback rule. The system qualitatively differs from other recently studied solvable chaotic hybrid systems in that the timing of the switching is regulated by an external clock. The chaotic analytic solution is an optimal waveform for communications in noise when a resistor-capacitor-integrate-and-dump filter is used as a receiver. As such, these results provide evidence in support of a recent conjecture that the optimal communication waveform for any stable infinite-impulse response filter is chaotic.

We assess the scope and status of these projects and report on challenges implementing them. We suggest that all intensively monitored watersheds should contain key elements based on sound experimental design concepts and be implemented within an adaptive management framework to maximize learning. The most significant challenges reported by groups were (1) improving coordination between funders, restoration groups, and researchers so that restoration and monitoring actions occur based on the project design and (2) maintaining consistent funding to conduct annual monitoring and evaluation of data. However, we conclude that despite these challenges, the intensively monitored watershed approach is the most reliable means of assessing the efficacy of watershed-scale restoration.

Three general habitats were surveyed: grasses (grasses and herbaceous and crawling vegetation), forests (pine, larch, deciduous, and mixed), and forests+grasses. A total of 27,029 ticks (1,534 adults; 11,755 nymphs; 13,740 larvae) belonging to three genera and five species were collected. Haemaphysalis longicornis (64.76%; 17,504) was the most commonly collected tick, followed by Haemaphysalis flava (29.22%; 7,899), Ixodes nipponensis (5.83%; 1,575), Amblyomma testudinarium (0.17%; 46), and Haemaphysalis phasiana (0.02%; 5). Overall, adult ticks accounted for only 5.68% of all ticks collected, while nymphs and larvae accounted for 43.49% and 50.83%, respectively. Haemaphysalis longicornis nymphs were commonly collected from April-June, followed by increased numbers of adults from June-August, and large numbers of larvae from August-September, while low numbers of all stages were collected during October. Haemaphysalis flava adults and nymphs were commonly collected from April-June and September-October, while large numbers of larvae were collected from July-August. Although fewer I. nipponensis were collected, seasonal developmental stage patterns followed those of H. flava. Similar proportions of males (47.96%) and females (52.04%) of H. flava were collected. However, the proportion of H. longicornis females (85.83%) collected was significantly higher than for males (14.17%), while the proportion of I. nipponensis males (57.62%) was significantly higher than for females (42.38%). Overall, the mean number of ticks collected/hour of collection was highest for forests+grasses (108.54), followed by grasses (97.28) and forests (66.64).

TI Botulinum and Tetanus Neurotoxin-Induced Blockade of Synaptic Transmission in Networked Cultures of Human and Rodent Neurons SO TOXICOLOGICAL SCIENCES LA English DT Article DE neurons; botulinum toxins; tetanus toxin; synaptic transmission; electrophysiology; spontaneous postsynaptic currents ID TOXIN TYPE-A; IN-VIVO; MOLECULAR-MECHANISMS; HIPPOCAMPAL-NEURONS; CELL-CULTURE; STEM-CELLS; SYNAPSES; RELEASE; ASSAY; IDENTIFICATION AB Clinical manifestations of tetanus and botulism result from an intricate series of interactions between clostridial neurotoxins (CNTs) and nerve terminal proteins that ultimately cause proteolytic cleavage of SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins and functional blockade of neurotransmitter release. Although detection of cleaved SNARE proteins is routinely used as a molecular readout of CNT intoxication in cultured cells, impaired synaptic function is the pathophysiological basis of clinical disease. Work in our laboratory has suggested that the blockade of synaptic neurotransmission in networked neuron cultures offers a phenotypic readout of CNT intoxication that more closely replicates the functional endpoint of clinical disease. Here, we explore the value of measuring spontaneous neurotransmission frequencies as novel and functionally relevant readouts of CNT intoxication. The generalizability of this approach was confirmed in primary neuron cultures as well as human and mouse stem cell-derived neurons exposed to botulinumneurotoxin serotypes A-G and tetanus neurotoxin. The sensitivity and specificity of synaptic activity as a reporter of intoxication was evaluated in assays representing the principal clinical and research purposes of in vivo studies. Our findings confirm that synaptic activity offers a novel and functionally relevant readout for the in vitro characterizations of CNTs. They further suggest that the analysis of synaptic activity in neuronal cell cultures can serve as a surrogate for neuromuscular paralysis in the mouse lethal assay, and therefore is expected to significantly reduce the need for terminal animal use in toxin studies and facilitate identification of candidate therapeutics in cell-based screening assays.

Compositional changes and varying electron density markedly affect the position and intensity of the plasmon resonance. We report a photo chemically induced" phenomenon of modulating the plasmon resonance in a controlled fashion. As photo generated reduced methyl viologen radicals transfer electrons to Cu2-xS in inert solutions, " we observe a decrease in localized surface plasmon resonance (LSPR) absorbance at 1160 nm. Upon exposure to air, the plasmon resonance band recovers as stored electrons are scavenged away by oxygen. This cycle of electron charge and discharge of Cu2-xS nanocrystals is reversible and can be repeated through photoirradiation in N-2 saturated solution followed by exposure of the suspension to air. The spectroscopic studies that provide mechanistic insights into the reversible charging and discharging of plasmonic Cu2-xS are discussed.

The skill of such predictions derives from the ability to estimate a watershed's initial moisture and energy conditions and to forecast future weather and climate. These sources of predictability are investigated in an idealized (i.e., perfect model) experiment using calibrated hydrologic simulation models for 424 watersheds that span the continental United States. Prior work in this area also followed an ensemble-based strategy for attributing streamflow forecast uncertainty, but focused only on two end points representing zero and perfect information about future forcings and initial conditions. This study extends the prior approach to characterize the influence of varying levels of uncertainty in each area on streamflow prediction uncertainty. The sensitivities enable the calculation of flow forecast skill elasticities (i.e., derivatives) relative to skill in either predictability source, which are used to characterize the regional, seasonal, and predictand variations in flow forecast skill dependencies. The resulting analysis provides insights on the relative benefits of investments toward improving watershed monitoring (through modeling and measurement) versus improved climate forecasting. Among other key findings, the results suggest that climate forecast skill improvements can be amplified in streamflow prediction skill, which means that climate forecasts may have greater benefit for monthly-to-seasonal flow forecasting than is apparent from climate forecast skill considerations alone. The results also underscore the importance of advancing hydrologic modeling, expanding watershed observations, and leveraging data assimilation, all of which help capture initial hydrologic conditions that are often the dominant influence on hydrologic predictions.

Therefore, ICP etching is a promising process for pattern transfer required during microelectronic and optoelectronic fabrication. Resonator-quantum well infrared photodetectors (R-QWIPs) are the next generation of QWIP detectors that use resonances to increase the quantum efficiency (QE). To fabricate R- QWIP focal plane arrays (FPAs), two optimized ICP etching processes are developed. Using these etching techniques, we have fabricated R- QWIP FPAs of several different formats and pixel sizes with the required dimensions and completely removed the substrates of the FPAs. Their QE spectra were tested to be 30 to 40%. The operability and spectral non-uniformity of the FPA is similar to 99.5 and 3%, respectively. (C) The Authors.

This analysis is used to construct microscale yield surfaces for selected deformation mechanisms in rolled AZ31B. Two-dimensional projections of these surfaces are plotted along sample directions to quantify the relative activity of each mechanism for various loading conditions. By assigning each mechanism realistic strengths, the analysis is used to quantify the influence of each deformation mechanism on macroscale yield behaviour. Due to its simplicity, this analysis can be easily carried out to probe and visualize projections of material response in any part of stress space given the material's texture, its relevant deformation mechanisms and realistic initial strengths of these mechanisms.

The surrogate fuels feature increasing levels of compositional accuracy (i.e., increasing exactness in matching hydrocarbon structural characteristics) relative to the single target diesel fuel upon which the surrogate fuels are based. This approach was taken to assist in determining the minimum level of surrogate-fuel compositional accuracy that is required to adequately emulate the performance characteristics of the target fuel under different combustion modes. For each of the four surrogate fuels, an approximately 30 L batch was blended, and a number of the physical aid chemical properties were measured. This work documents the surrogate-fuel creation process= and the results of the property measurements. C1 [Mueller, Charles J.] Sandia Natl Labs, 7011 East Ave,MS 9053, Livermore, CA 94550 USA.

TI Efficient Attitude Estimation for a Spin-Stabilized Projectile SO JOURNAL OF GUIDANCE CONTROL AND DYNAMICS LA English DT Article ID FLIGHT AB An algorithm using an extended Kalman filter is presented for estimating the full attitude of a nose-controlled spin-stabilized projectile using magnetometers and a velocity vector estimate with increased computational efficiency. A dynamic model based on the projectile equations of motion is used in the predictor step of the Kalman filter. A new coordinate system is introduced that enables both the process and measurement models of the Kalman filter to be described by linear, slowly time-varying systems. This property is exploited to generate a steady-state Kalman filter which per current knowledge, has never been done for this problem. Both the extended Kalman filter and steady-state Kalman filter are shown to perform well in simulation studies, and the difference in performance between the two filters is very small.

Subjects walked on a treadmill at 0% and 15% grades for 30 min while we recorded electroencephalography (EEG). We used independent component (IC) analysis to parse EEG signals into maximally independent sources and then computed dipole estimations for each IC. We clustered cortical source ICs and analyzed event-related spectral perturbations synchronized to gait events. Theta power fluctuated across the gait cycle for both conditions, but was greater during incline walking in the anterior cingulate, sensorimotor and posterior parietal clusters. We found greater gamma power during level walking in the left sensorimotor and anterior cingulate clusters. We also found distinct alpha and beta fluctuations, depending on the phase of the gait cycle for the left and right sensorimotor cortices, indicating cortical lateralization for both walking conditions. We validated the results by isolating movement artifact. We found that the frequency activation patterns of the artifact were different than the actual EEG data, providing evidence that the differences between walking conditions were cortically driven rather than a residual artifact of the experiment. These findings suggest that the locomotor pattern adjustments necessary to walk on an incline compared with level surface may require supraspinal input, especially from the left sensorimotor cortex, anterior cingulate, and posterior parietal areas. These results are a promising step toward the use of EEG as a feed-forward control signal for ambulatory brain-computer interface technologies. C1 [Bradford, J.

TI Thirty-Day Outcomes after Elective Percutaneous or Open Endovascular Repair of Abdominal Aortic Aneurysms SO ANNALS OF VASCULAR SURGERY LA English DT Article ID QUALITY IMPROVEMENT PROGRAM; PRECLOSE TECHNIQUE; ACCESS; EXPERIENCE; SUCCESS AB Background: Percutaneous endovascular aneurysm repair (PEVAR) has become accepted as a suitable alternative to open EVAR (OEVAR) in the treatment of abdominal aortic aneurysms (AAAs). Direct comparisons between the 2 techniques have been infrequently reported and have predominantly focused on immediate procedural outcomes. The objective of this study was to compare contemporary 30-day postoperative outcomes between successfully completed elective PEVAR and OEVAR. Methods: The 2012 National Surgical Quality Improvement Program database was queried for all elective primary AAA repairs. Procedures on ruptured AAAs and those involving adjunctive thoracic, abdominal, or extremity procedures were excluded. Cases completed with at least one surgical exposure of the femoral artery for access (OPEN) were compared with those completed without such exposure (PERC). Preoperative, intraoperative, and 30-day postoperative variables were compared using appropriate univariate statistical tests. A P value of <= 0.05 was considered significant for all comparisons. Results: A total of 1,589 (51%) OPEN and 1,533 (49%) PERC cases met inclusion and exclusion criteria. Preoperative characteristics did not differ between groups. OPEN cases took significantly longer (150 +/- 69 min) than PERC cases (134 +/- 65 min, P < 0.001). No significant differences were found between the groups in any postoperative occurrence, but the rate of venous thromboembolism twice as high in OPEN (16, 1.0%) than PERC cases (7, 0.5%, P = 0.07). In addition, wound complications (36, 2.3% OPEN vs. 23, 1.3% PERC, P = 0.11) were more common in OPEN cases but were diagnosed a week sooner on average in PERC cases (19 days OPEN and 12 days PERC). Median postoperative length of stay was 2 days among OPEN cases versus 1 day in PERC cases (P = 0.11). Female gender and obesity predicted wound complications in the OPEN group but not in the PERC group. Conclusions: Successfully completed PEVAR and OEVAR have similar rates of overall complications. Female gender and obesity predict wound complications in OEVAR but not in PEVAR, which appears to be a safe alternative to OEVAR. PEVAR has the advantage of shorter operative time and the potential for a shorter postoperative stay, and may offer the advantage of fewer wound complications in females and obese patients.

TI Drug-Motivated Behavior in Rats With Lesions of the Thalamic Orosensory Area SO BEHAVIORAL NEUROSCIENCE LA English DT Article DE trigeminal orosensory area; thalamus; motivated behavior; morphine; cocaine ID PHYSICAL-DEPENDENCE LIABILITY; CONDITIONED PLACE PREFERENCE; PAIRED TASTE CUE; LITHIUM-CHLORIDE; SACCHARIN INTAKE; ANTICIPATORY CONTRAST; INDUCED SUPPRESSION; GUSTATORY THALAMUS; CORN-OIL; EXCITOTOXIC LESIONS AB Rats suppress intake of a palatable taste cue when paired with a rewarding or an aversive stimulus in appetitive or aversive conditioning, respectively. A similar phenomenon occurs with drugs of abuse, but the nature of this conditioning has been subject for debate. While relatively little is known about the underlying neural circuitry, we recently reported bilateral lesions of the thalamic trigeminal orosensory area isolate drug-induced suppression of intake of a taste cue. The lesion blocks avoidance of the taste cue when paired with experimenter delivered drugs of abuse, yet has no effect on avoidance of the same cue when paired with an aversive agent or when it predicts access to a highly palatable sucrose solution. We hypothesize the lesion may blunt the rewarding properties of the drug. To test this, we used a runway apparatus, as running speed has been shown to increase with increasing reward value. Our hypothesis was supported by failure of the lesioned rats to increase running speed for morphine. Interestingly, lesioned rats did avoid intake of the drug-paired cue when presented in the runway apparatus and displayed naloxone-precipitated withdrawal. Using a partial crossover design, the lesion prevented avoidance of a cocaine-paired cue when presented in the home cage. We conclude that the lesion disrupts avoidance of a taste cue in anticipation of the rewarding properties of a drug but, at least in the presence of contextual cues, allows for avoidance of a taste cue as it elicits the onset of an aversive conditioned state of withdrawal.

TI Randomized Controlled Trial to Compare Immunogenicity of Standard-Dose Intramuscular Versus Intradermal Trivalent Inactivated Influenza Vaccine in HIV-Infected Men Who Have Sex With Men in Bangkok, Thailand SO CLINICAL INFECTIOUS DISEASES LA English DT Article DE influenza; vaccine; HIV; immunogenicity; intradermal ID A H1N1 VACCINE; ANTIBODY-RESPONSE; HIV-1-INFECTED PATIENTS; IMMUNE-RESPONSE; CLINICAL-TRIAL; SPLIT VIRION; DOUBLE-BLIND; ADULTS; EFFICACY; INDIVIDUALS AB Background. Individuals infected with human immunodeficiency virus (HIV) are at increased risk for severe influenza, yet immune responses to standard-dose intramuscular (IM) influenza vaccine are suboptimal in this population. Intradermal (ID) delivery of influenza vaccine might improve immune response through enhanced stimulation of dendritic cells. Methods. We conducted a randomized, double-blind, controlled trial to compare the immunogenicity of off-label standard-dose (15 mu g) ID vs standard-dose (15 mu g) IM inactive influenza vaccine in HIV-infected men in Bangkok, Thailand. The primary study outcome was seroconversion (minimum titer of 1:40 and >= 4-fold rise in antibody titer) at 1 month postvaccination based on serum hemagglutination inhibition antibody titers against each vaccine strain. Adverse events (AEs) in the 7 days following vaccination were also assessed. Results. We enrolled 400 HIV-infected participants; 200 were randomly assigned to receive IM and 200 ID vaccine. Vaccine arms were well-balanced with respect to age, CD4 cell count, HIV RNA load, and antiretroviral treatment. Percentage of seroconversion to all (ID 14% vs IM 15%; P=.8) or at least 1 (ID 69% vs IM 68%; P=.7) of the 3 vaccine strains did not differ significantly between ID vs IM vaccine recipients. A higher proportion of participants who received ID vaccine had mild injection-site AEs compared with participants who received IM vaccine (77% vs 27%). Conclusions. There were no significant differences in the immunogenicity of standard-dose ID vs IM influenza vaccine in this HIV-infected population in Thailand. Additional strategies to enhance immune responses to influenza vaccine among HIV-infected persons are needed.

Since observations are not available at the same density as the model grid points, spatial and temporal error correlations must be specified in order to effectively assimilate the observations into the model. Overdrying is found while applying the Weather Research and Forecasting Model to five cases centered over Southern California. This overdrying is caused by incorporation of observations in the initial conditions both at a discrete time and over a preforecast data assimilation period. Nonphysical dryness results from the assumption that model moisture error at the observation location is correlated with model moisture error at other locations in the model without regard to the relative magnitude of the moisture at those two locations. Modifying the model and its preprocessor to remove this assumption greatly reduces the occurrence of excessive model dryness without degrading the overall model performance in predicting moisture.

However, analytical techniques that quantify and compare alternative research investments are increasingly recommended. Here, we apply value of information and portfolio decision analysis methods commonly applied in financial and operations management to prioritize risk research for multiwalled carbon nanotubes and nanoparticulate silver and titanium dioxide. We modify the widely accepted CB Nanotool hazard evaluation framework, which combines nano- and bulk-material properties into a hazard score, to operate probabilistically with uncertain inputs. Literature is reviewed to develop uncertain estimates for each input parameter, and a Monte Carlo simulation is applied to assess how different research strategies can improve hazard classification. The relative cost of each research experiment is elicited from experts, which enables identification of efficient research portfolios combinations of experiments that lead to the greatest improvement in hazard classification at the lowest cost. Nanoparticle shape, diameter, solubility and surface reactivity were most frequently identified within efficient portfolios in our results.

TI Permeability Measurements and Flow Simulation for Polyaniline Carbon Nanofibers Modified Nanopaper on Glass Fiber Preform SO POLYMER COMPOSITES LA English DT Article ID MECHANICAL-PROPERTIES; COMPOSITES; REINFORCEMENT; FABRICATION; ELASTOMERS; COATINGS; MOLDS; MATS; PART AB Carbon nanofibers (CNFs) nanopapers have shown great potential to improve the surface of fiber-reinforced polymeric composites, including providing electromagnetic interference shielding and erosion resistance. During typical resin transfer molding (RTM) process, the CNF nanopaper is incorporated into the fiber preform as a surface layer. To learn how resin flows through the fiber preform and nanopaper layer, permeabilities of the fiber preform and nanopaper need to be measured. As is well known, measuring the permeability of fiber preforms is experimentally challenging. Results usually exhibit large experimental variability. Measuring permeability of nanopapers is even more complicated. To improve the accuracy of results, permeability of CNF-based nanopapers was measured using different experimental setups. In-plane permeability of nanopaper was measured by both unidirectional microslit flow and radial flow approaches. Trans-plane permeability was measured as well, using a trans-plane flow cell and a flow visualization mold. In this article, we discuss the methods used and provide experimental results. We also conducted computational fluid dynamics simulations to study the detailed flow patterns of the nanopaper/RTM process and compared the simulated effect of the nanopaper on retarding the flow (length of the lag) with respect to the glass preform with flow visualization results.

In this study, formulations consisting of 90% hexanitro-hexaazaisowurtzitane (CL-20) or cyclotrimethylene trinitramine (RDX) and 10% polyvinyl alcohol (PVOH) were prepared with mean crystal sizes ranging from 200nm to 2m. The process to create these materials used a combination of aqueous mechanical crystal size reduction and spray drying. The basic physical characteristics of these formulations were determined using a variety of techniques, including scanning electron microscopy, X-ray diffraction, and Raman spectroscopy. Compressive stress-strain tests on pressed pellets revealed that the mechanical properties of the compositions improved with decreasing crystal size, consistent with Hall-Petch mechanics. In the most extreme case (involving CL-20/PVOH formulations), crystal size reduction from 2m to 300nm improved compressive strength and Young's modulus by 126% and 61%, respectively. These results serve to highlight the relevance of structure-property relationships in explosive compositions, and particularly elucidate the substantial benefits of reducing the high explosive crystal size to nanoscale dimensions.

While the highest density and stability of HEs is only attainable in the crystalline state, the unique properties exhibited by glasses may offer significant practical advantages. In this work, the production and properties of glassy molecular dispersions based on CL-20 with HMX and polyvinyl acetate additives were investigated. The glassy form was achieved by rapid precipitation of the composite ingredients using spray drying. The role of the additives on glass formation was examined. Characterization revealed multiple novel properties in comparison to the traditional crystalline HE-based compositions. Differential scanning calorimetry (DSC) analysis showed that in the glassy state the materials have a higher configurational enthalpy, by as much as 42Jg(-1). Thermomechanical analysis (TMA) results indicate that the glassy materials undergo a glass transition at around 50 degrees C, during which a transformation from a rigid to a liquid-like state occurs. The glasses showed a tendency to crystallize, as was observed with TMA and DSC analysis. It was observed that the stability of the amorphous phase with respect to crystallization improved with increasing pellet density. These findings serve to highlight the unique opportunity presented by glassy energetics to achieve improvements beyond those attainable with traditional crystalline materials.

TI Combustion of Energetic Porous Silicon Composites Containing Different Oxidizers SO PROPELLANTS EXPLOSIVES PYROTECHNICS LA English DT Article DE Porous silicon; On-chip energetic materials; Combustion; Sulfur; Nitrate ID FILMS AB We present a quantitative investigation of combustion of on-chip porous silicon (PS) energetic materials using oxidizers with improved moisture stability and/or minimized environmental impact compared to sodium perchlorate (NaClO4). Material properties of the PS films were characterized using gas adsorption porosimetry and profilometry to determine specific surface area, porosity, and etch depth. PS energetic composites were formed using melt-penetrated or solution-deposited oxidizers into the pores. Combustion was characterized by high speed imaging and bomb calorimetry. The flame speeds quantified for PS/sulfur and PS/nitrate systems varied in the ranges of 2.9-3.7ms(-1)and 3.1-21ms(-1), respectively. The experimental combustion enthalpies are reported for different oxidizer systems in both inert and oxidizing environments. For the PS/sulfur and the PS/nitrate systems, the experimental heats of combustion were comparable to those calculated for the thermodynamic equilibrium and taking into account an increased reactivity of PS due to the hydrogen terminated silicon surface.

Highly immunodeficient mouse strains, such as NOD/SCID/gamma chain(null) (NSG, NOG), support better human hematopoietic cell engraftment. Another improvement is the derivation of highly immunodeficient mice, transgenic with human leukocyte antigens (HLAs) and cytokines that supported development of HLA-restricted human T cells and heightened human myeloid cell engraftment. Humanized mice are also used to study the HIV reservoir using new imaging techniques. Despite these advances, there are still limitations in HIV immune responses and deficits in lymphoid structures in these models in addition to xenogeneic graft-versus-host responses. To understand and disseminate the improvements and limitations of humanized mouse models to the scientific community, the NIH sponsored and convened a meeting on April 15, 2015 to discuss the state of knowledge concerning these questions and best practices for selecting a humanized mouse model for a particular scientific investigation. This report summarizes the findings of the NIH meeting. C1 [Akkina, Ramesh] Colorado State Univ, Dept Microbiol Immunol & Pathol, Ft Collins, CO 80523 USA.

TI The Functional Movement Screen and Injury Risk: Association and Predictive Value in Active Men SO AMERICAN JOURNAL OF SPORTS MEDICINE LA English DT Article DE military training; epidemiology; injury prevention; Functional Movement Screen; predictive value ID INTERRATER RELIABILITY; INTRARATER RELIABILITY; INFANTRY; SOLDIERS; FITNESS AB Background: The Functional Movement Screen (FMS) is a series of 7 tests used to assess the injury risk in active populations. Purpose: To determine the association of the FMS with the injury risk, assess predictive values, and identify optimal cut points using 3 injury types. Study Design: Cohort study; Level of evidence, 2. Methods: Physically active male soldiers aged 18 to 57 years (N = 2476) completed the FMS. Demographic and fitness data were collected by survey. Medical record data for overuse injuries, traumatic injuries, and any injury 6 months after the FMS assessment were obtained. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated along with the receiver operating characteristic (ROC) to determine the area under the curve (AUC) and identify optimal cut points for the risk assessment. Risks, risk ratios (RRs), odds ratios (ORs), and 95% CIs were calculated to assess injury risks. Results: Soldiers who scored 14 were at a greater risk for injuries compared with those who scored >14 using the composite score for overuse injuries (RR, 1.84; 95% CI, 1.63-2.09), traumatic injuries (RR, 1.26; 95% CI, 1.03-1.54), and any injury (RR, 1.60; 95% CI, 1.45-1.77). When controlling for other known injury risk factors, multivariate logistic regression analysis identified poor FMS performance (OR [score 14/19-21], 2.00; 95% CI, 1.42-2.81) as an independent risk factor for injuries. A cut point of 14 registered low measures of predictive value for all 3 injury types (sensitivity, 28%-37%; PPV, 19%-52%; AUC, 54%-61%). Shifting the injury risk cut point of 14 to the optimal cut points indicated by the ROC did not appreciably improve sensitivity or the PPV. Conclusion: Although poor FMS performance was associated with a higher risk of injuries, it displayed low sensitivity, PPV, and AUC. On the basis of these findings, the use of the FMS to screen for the injury risk is not recommended in this population because of the low predictive value and misclassification of the injury risk.

TI Energy dissipation in intercalated carbon nanotube forests with metal layers SO APPLIED PHYSICS A-MATERIALS SCIENCE & PROCESSING LA English DT Article ID MECHANICAL-PROPERTIES; COMPOSITES; GROWTH; ARRAYS; WIRES; TIPS AB Vertically aligned carbon nanotube (CNT) forests were synthesized to study their quasi-static mechanical properties in a layered configuration with metallization. The top and bottom surfaces of CNT forests were metalized with Ag, Fe, and In using paste, sputtering, and thermal evaporation, respectively. Stacks of one, two, and three layers of these forests were assembled and compressed to measure their mechanical properties. The samples were strain limited to 0.7, and the results indicate that energy dissipation is approximately linear with respect to the number of layers and relatively independent of metal type. The energy per unit volume was approximately the same for all samples. Successive stacking of CNT forests reduces local buckling events, which is enhanced with a thick Ag deposition on the CNT forest surface. Young's modulus was also observed to increase as the number of layers was increased. These results are useful in the design of composite materials for high energy absorption and high stiffness applications.

SM cutaneous lesions are characterized by both vesication and severe inflammation, but the molecular mechanisms that lead to these signs and symptoms are not well understood. There is a pressing need for effective therapeutics to treat this injury. An understanding of the molecular mechanisms of injury and identification of potential therapeutic targets is necessary for rational therapeutic development. We have applied a high-throughput small interfering RNA (siRNA) screening approach to the problem of SM cutaneous injury in an effort to meet these needs. Our siRNA screening efforts have initially focused on SM-induced inflammation in cutaneous injury since chronic inflammation after exposure appears to play a role in progressive clinical pathology, and intervention may improve clinical outcome. Also, targets that mitigate cellular injury should reduce the inflammatory response. Historical microarray data on this injury were mined for targets and pathways implicated in inflammation, and a siRNA library of 2,017 targets was assembled for screening. Primary screening and library deconvolution were performed using human HaCaT keratinocytes and focused on cell death and inflammatory markers as end points. Using this in vitro approach, we have identified and validated novel targets for the potential treatment of SM-induced cutaneous injury.

The International Medical Prevention Registry on Venous Thromboembolism (IMPROVE) bleeding risk score (BRS) was derived from a well-defined population of medical inpatients but it has not been validated externally. We sought to externally validate the IMPROVE BRS. METHODS: We prospectively collected characteristics on admission and VTE prophylaxis data each hospital day for all patients admitted for a medical illness to the Walter Reed Army Medical Center over an 18-month period. We calculated the IMPROVE BRS for each patient using admission data and reviewed medical records to identify bleeding events. RESULTS: From September 2009 through March 2011, 1,668 inpatients met the IMPROVE inclusion criteria. Bleeding events occurred during 45 separate admissions (2.7%); 31 events (1.9%) were major and 14 (0.8%) were nonmajor but clinically relevant. Two hundred fiftysix patients (20.7%) had an IMPROVE BRS >= 7.0. Kaplan-Meier curves showed a higher cumulative incidence of major (P = .02) and clinically important (major plus clinically relevant nonmajor) (P = .06) bleeding within 14 days in patients with an IMPROVE BRS >= 7.0. An IMPROVE BRS >= 7.0 was associated with major bleeding in Cox-regression analysis adjusted for administration of chemical prophylaxis (OR, 2.6; 95% CI, 1.1-5.9; P = .03); there was a trend toward a significant association with clinically important bleeding (OR, 1.9; 95% CI, 0.9-3.7; P = .07). CONCLUSIONS: The IMPROVE BRS calculated at admission predicts major bleeding in medical inpatients. This model may help assess the relative risks of bleeding and VTE before chemoprophylaxis is administered.

In addition, we assessed adherence and response to positive airway pressure (PAP) therapy in this population. METHODS: This was a case-controlled observational cohort study at the Sleep Disorders Center of an academic military medical center. Two hundred consecutive patients with PTSD underwent sleep evaluations. Patients with PTSD with and without OSAS were compared with 50 consecutive age-matched patients with OSAS without PTSD and 50 age-matched normal control subjects. Polysomnographic data, sleep-related symptoms and QoL measures, and objective PAP usage were obtained. RESULTS: Among patients with PTSD, more than one-half (56.6%) received a diagnosis of OSAS. Patients with PTSD and OSAS had lower QoL and more somnolence compared with the other groups. Patients with PTSD demonstrated significantly lower adherence and response to PAP therapy. Resolution of sleepiness occurred in 82% of patients with OSAS alone, compared with 62.5% of PAP-adherent and 21.4% of nonadherent patients with PTSD and OSAS (P < .001). Similarly, posttreatment Functional Outcomes of Sleep Questionnaire >= 17.9 was achieved in 72% of patients with OSAS, compared with only 56.3% of patients with PTSD and OSA who were PAP adherent and 26.2% who were nonadherent (P < .03). CONCLUSIONS: In patients with PTSD, comorbid OSAS is associated with worsened symptoms, QoL, and adherence and response to PAP. Given the negative impact on outcomes, the possibility of OSAS should be considered carefully in patients with PTSD. Close follow-up is needed to optimize PAP adherence and efficacy in this at-risk population.

TI Sympathetic regulation of blood pressure in normotension and hypertension: when sex matters SO EXPERIMENTAL PHYSIOLOGY LA English DT Article ID RENIN-ANGIOTENSIN SYSTEM; POINT CHRONIC ACTIVATION; ALL-CAUSE MORTALITY; NERVE ACTIVITY; DOMINANT CONTRIBUTOR; ARTERIAL STIFFNESS; POSTMENOPAUSAL WOMEN; AUTONOMIC SUPPORT; COUNTERPOINT ACTIVATION; CARDIOVASCULAR EVENTS AB New Findings What is the topic of this review? Hypertension is a major problem in Western society. Risk of hypertension increases with age, especially in women, who have lower risk compared with men until menopause. This review outlines the sex differences in the sympathetic control of blood pressure and how these mechanisms change with age. What advances does it highlight? It has recently been recognized that men and women regulate blood pressure by different physiological mechanisms. This is important for both the understanding and the clinical management of individual patients with hypertension. This review summarizes recent advances in understanding how the regulation of blood pressure in hypertension by the sympathetic nervous system differs between men and women. The sympathetic nervous system has a central role in the regulation of arterial blood pressure (BP) and in the development of hypertension in humans. Recent evidence points to differences between the sexes in the integrative mechanisms by which BP is controlled, suggesting that the development of hypertension may follow distinct pathways in women compared with men. An important aspect of sympathetic control of BP is its substantial interindividual variability. In healthy young men, the variability in sympathetic nerve activity (SNA) is balanced by variability in cardiac output and vascular adrenergic responses, such that BP remains similar, and normal, across a severalfold range of resting SNA values. In young women, variability in resting SNA is similar to that seen in men, but the balancing' mechanisms are strikingly different; women exhibit greater -adrenergic vasodilatation compared with men, which minimizes the pressor effects of a given level of SNA. Ageing is associated with increased SNA and a loss of the balancing factors seen in younger people, leading to an increased risk of hypertension in older people. Loss of oestrogen with menopause in women appears to be linked mechanistically with the decrease in -adrenergic vasodilatation and the increased risk of hypertension in older women. Other important factors contributing to hypertension via sympathetic mechanisms are obesity and arterial stiffening, both of which increase with ageing. We conclude with a discussion of important areas in which more work is needed to understand and manage appropriately the sex-specific mechanisms in the development and maintenance of hypertension.

TI Outcomes and Return to Activity After Operative Repair of Chronic Latent Syndesmotic Instability SO FOOT & ANKLE INTERNATIONAL LA English DT Article DE arthritis; biomechanics; sports; trauma; outcome studies ID DISTAL TIBIOFIBULAR SYNDESMOSIS; RADIOGRAPHIC EVALUATION; ANKLE SYNDESMOSIS; DIAGNOSIS; ARTHROSCOPY; FIXATION; FRACTURE; SPRAINS AB Background: This study is a retrospective review of prospectively gathered data determining the postoperative outcomes of patients who underwent operative treatment to address chronic syndesmotic instability. Methods: The cohort is composed of 19 individuals who elected to undergo operative treatment of chronic syndesmotic instability. The operative repair consisted of arthroscopic debridement in all cases with reduction and suture button fixation of those patients who had greater than 4 mm of syndesmotic diastasis on arthroscopic evaluation. All patients had a minimum of 24 months follow-up. This study retrospectively examined the prospectively gathered preoperative and postoperative outcome scores to include a Visual Analog Scale (VAS) pain score and an American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score. In addition, patients were questioned on their ability to return to their preinjury level of activity and their ability to continue running sports. Fourteen patients returned their postoperative surveys. Results: Mean AOFAS scores improved significantly from 48 to 82.7 (P = .014). Mean VAS scores improved from 6.1 to 1.0 (P = .002). Overall, 86% (12/14) of patients were able to return to running and 79% (11/14) of patients were able to return to their preinjury level of sport. Preoperative and postoperative weight-bearing ankle radiographs were reviewed to evaluate the tibiofibular clear space and overlap. The clear space measured on anteroposterior (AP) radiographs decreased from 5.4 mm to 4.6 mm (P = .005), the clear space evaluated on the mortise radiograph decreased from 4.5 mm to 3.6 mm (P = .006), and the overlap measured on the AP radiograph increased from 5.7 mm to 6.9 mm (P = .019). All radiographs were measured by a board-certified musculoskeletal radiologist. Conclusion: This study presents a treatment method that can be instituted at the time of diagnosis for syndesmotic injuries with greater than 4 mm of diastasis that were treated with debridement and stabilization. The results of this treatment technique are promising, with significant improvements in subjective outcome scores and a high rate of return to running sports.

TI Management of Postoperative Pain: A Clinical Practice Guideline From the American Pain Society, the American Society of Regional Anesthesia and Pain Medicine, and the American Society of Anesthesiologists' Committee on Regional Anesthesia, Executive Committee, and Administrative Council SO JOURNAL OF PAIN LA English DT Article DE Postoperative pain management; clinical practice guidelines; analgesia; education; multi-modal therapy; patient assessment; regional analgesia; neuraxial analgesia ID TOTAL KNEE ARTHROPLASTY; CRUCIATE LIGAMENT RECONSTRUCTION; PATIENT-CONTROLLED ANALGESIA; RANDOMIZED CONTROLLED-TRIAL; ELECTRICAL NERVE-STIMULATION; NONSTEROIDAL ANTIINFLAMMATORY DRUGS; INTRAARTICULAR BUPIVACAINE INFUSION; PERSISTENT POSTSURGICAL PAIN; LIDOCAINE-PRILOCAINE CREAM; PLACEBO-CONTROLLED TRIAL AB Most patients who undergo surgical procedures experience acute postoperative pain, but evidence suggests that less than half report adequate postoperative pain relief. Many preoperative, intra-operative, and postoperative interventions and management strategies are available for reducing and managing postoperative pain. The American Pain Society, with input from the American Society of Anesthesiologists, commissioned an interdisciplinary expert panel to develop a clinical practice guideline to promote evidence-based, effective, and safer postoperative pain management in children and adults. The guideline was subsequently approved by the American Society for Regional Anesthesia. As part of the guideline development process, a systematic review was commissioned on various aspects related to various interventions and management strategies for postoperative pain. After a review of the evidence, the expert panel formulated recommendations that addressed various aspects of postoperative pain management, including preoperative education, perioperative pain management planning, use of different pharmacological and nonpharmacological modalities, organizational policies, and transition to outpatient care. The recommendations are based on the underlying premise that optimal management begins in the preoperative period with an assessment of the patient and development of a plan of care tailored to the individual and the surgical procedure involved. The panel found that evidence supports the use of multimodal regimens in many situations, although the exact components of effective multi modal care will vary depending on the patient, setting, and surgical procedure. Although these guidelines are based on a systematic review of the evidence on management of postoperative pain, the panel identified numerous research gaps. Of 32 recommendations, 4 were assessed as being supported by high-quality evidence, and 11 (in the areas of patient education and perioperative planning, patient assessment, organizational structures and policies, and transitioning to outpatient care) were made on the basis of low-quality evidence.

TI The Effect of Target Position on the Accuracy of Cervical-Spine-Rotation Active Joint-Position Sense SO JOURNAL OF SPORT REHABILITATION LA English DT Article DE proprioception; neck; helicopter pilots ID CERVICOCEPHALIC KINESTHETIC SENSIBILITY; NECK PAIN; SENSORIMOTOR SYSTEM; WHIPLASH INJURY; MUSCLE-SPINDLES; MOTION; MANAGEMENT; RANGE; HEAD; PROPRIOCEPTION AB Context: The cervical spine can be divided into upper and lower units, each making a different contribution to the magnitude of rotation and proprioception. However, few studies have examined the effect of the cervical rotation positions on proprioception. Objective: To compare cervical-spine rotation active joint-position sense (AJPS) near midrange of motion (mid-ROM; 30 degrees) and near end-ROM (60 degrees). Design: Cross-sectional study. Setting: Human performance research laboratory. Participants: 53 military helicopter pilots (age 28.4 +/- 6.2 y, height 175.3 +/- 9.3 cm, weight 80.1 +/- 11.8 kg). Main Outcome Measures: A motion-analysis system was used to record cervical-rotation kinematics. Subjects sat in a chair wearing a headband and blindfold. First, they actively rotated the head right or left to a target position (30 degrees/60 degrees), with real-time verbal cues provided by the tester. Subjects held the target position for 5 s and then returned to the start position. After this, they replicated the target position as closely as possible. Five trials were performed in both directions to both target positions (R30/R60/L30/L60). Order of direction/position was randomized. The difference between target and replicated positions was calculated and defined as absolute error (AE), and the mean of 5 trials was used for analyses. Wilcoxon signed-ranks tests were used to compare AJPS at the different target positions (P <.0125 with Bonferroni adjustments). Results: End-ROM AEs were significantly more accurate than mid-ROM AEs (P =.001). Conclusion: Cervical-spine-rotation AJPS is more accurate near end-ROM than mid-ROM. Both target positions should be used to examine cervical-spine-rotation AJPS of both the upper and lower units. C1 [Nagai, Takashi] Univ Pittsburgh, Dept Sports Med & Nutr, Pittsburgh, PA USA.

A two-year case study was conducted in the San Antonio and Guadalupe basins during dry and wet years (2008 and 2009, respectively). This article investigates TN export in urbanized (San Antonio) vs. rural (Guadalupe) drainage basins and considers the effect of reservoirs on TN transport. Simulated TN export values are within 10 percent of measured export values for selected stations in 2008 and 2009. Results show that in both years the San Antonio basin contributed a larger quantity than the Guadalupe basin of delivered TN to the coastal ocean. The San Antonio basin is affected by urban activities including point sources, associated with the city of San Antonio, in addition to greater agricultural activities. The Guadalupe basin lacks major metropolitan areas and is dominated by rangeland, rather than fertilized agricultural fields. Both basins delivered more TN to coastal waters in 2009 than in 2008. Furthermore, TN removal in the San Antonio and Guadalupe basins is inversely related to stream orders: the higher the order the more TN delivery (or the less TN removal).

TI BENCHMARKING OPTICAL/THERMAL SATELLITE IMAGERY FOR ESTIMATING EVAPOTRANSPIRATION AND SOIL MOISTURE IN DECISION SUPPORT TOOLS SO JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION LA English DT Article DE soil moisture; evapotranspiration; GSSHA; SEBAL; METRIC; DPWM; distributed hydrologic modeling; optical/thermal satellite imagery; Landsat; MODIS; groundwater recharge; water management; hydrograph ID ENERGY BALANCE ALGORITHM; CROP COEFFICIENT METHOD; LATENT-HEAT FLUXES; ROOT WATER-UPTAKE; OPTICAL IMAGERY; MAPPING EVAPOTRANSPIRATION; ESTIMATING EVAPORATION; MODEL; SURFACE; LAND AB Generally, one expects evapotranspiration (ET) maps derived from optical/thermal Landsat and MODIS satellite imagery to improve decision support tools and lead to superior decisions regarding water resources management. However, there is lack of supportive evidence to accept or reject this expectation. We benchmark three existing hydrologic decision support tools with the following benchmarks: annual ET for the ET Toolbox developed by the United States Bureau of Reclamation, predicted rainfall-runoff hydrographs for the Gridded Surface/Subsurface Hydrologic Analysis model developed by the U.S. Army Corps of Engineers, and the average annual groundwater recharge for the Distributed Parameter Watershed Model used by Daniel B. Stephens & Associates. The conclusion of this benchmark study is that the use of NASA/USGS optical/thermal satellite imagery can considerably improve hydrologic decision support tools compared to their traditional implementations. The benefits of improved decision making, resulting from more accurate results of hydrologic support systems using optical/thermal satellite imagery, should substantially exceed the costs for acquiring such imagery and implementing the remote sensing algorithms. In fact, the value of reduced error in estimating average annual groundwater recharge in the San Gabriel Mountains, California alone, in terms of value of water, may be as large as $1 billion, more than sufficient to pay for one new Landsat satellite.

Study Design and Setting A retrospective review of bibliographic references in 5 otolaryngology journals. Subjects and Methods Five high-impact otolaryngology journals were reviewed over a 3-month period between January and March 2014 to identify the pattern of author self-citations. Data included study type, otolaryngology topic, authorship, total citations, author self-citations, and country of origin. Results Nearly two-thirds of articles contained at least 1 self-citation, with an average of 2.6 self-citations per article. Self-citations represented nearly 10% of total citations. Articles with at least 1 self-citation had more authors (5.8 vs 4.9, P < .01) and more citations (30.4 vs 22.2, P < .01) per article than did those without self-citations. There was no difference in self-citation practices between articles originating within the United States and abroad (P = .65). Last authors were the most frequent self-citers and were more likely than lead authors to cite themselves (P < .01). Original reports contained the highest percentage of self-citations per article as compared with reviews and case reports (P < .01). Conclusion Author self-citation in the otolaryngology literature is common and compares similarly to other medical specialties previously studied. Self-citation should not be considered inappropriate, as it is often done to expand on earlier research. Nevertheless, editors, researchers, and readers should be aware of this increasingly recognized phenomenon and its associated potential implications to the process of scientific inquiry.

Identifying optimal resuscitation products for restoring plasma homeostasis following injury is important for improving management of these patients.Objectives:To determine the effects of crystalloid versus plasma resuscitation on thrombin generation in a rat model of trauma and hemorrhagic shock (HS).Patients/Methods:Rats were subjected to trauma and HS followed by resuscitation with Lactated Ringer's solution (LR) or fresh frozen plasma (FFP). Blood was collected at baseline, decompensation, and 3-h post-resuscitation. Thrombin generation was measured by calibrated automated thrombogram and antithrombin III (AT) by ELISA. In a prospective observational study, admission blood samples were collected on highest-level activation trauma patients and diluted with LR or FFP for thrombin generation analysis.Results:Resuscitation with LR resulted in persistent hypercoagulability; however, FFP resuscitation reversed this hypercoagulability to baseline thrombin generation or below. Plasma AT levels decreased following HS and remained low in rats receiving LR, but were corrected in rats receiving FFP. Similarly, in trauma patient plasma LR increased thrombin generation while FFP reduced it. However, results with AT-deficient plasma dilution were similar to LR. In patients with admission hypocoagulability, FFP slightly increased thrombin generation.Conclusions:HS in rats is associated with increased thrombin generation and resuscitation with FFP, not LR, reverses hypercoagulability. Dilution of trauma patient plasma with LR or FFP yielded similar results; however, the modulatory effects of FFP were attenuated when AT was absent. Importantly, FFP reduced thrombin generation in hypercoagulable patient plasma, but slightly increased thrombin generation in hypocoagulable patient plasma. Thus, FFP restores hemostatic balance following trauma and HS which is, in part, by delivering AT.

TI ENDOTHELIUM-DERIVED INHIBITORS EFFICIENTLY ATTENUATE THE AGGREGATION AND ADHESION RESPONSES OF REFRIGERATED PLATELETS SO SHOCK LA English DT Article DE Apheresis platelets; cold storage; hemostatic function; inhibition ID NITRIC-OXIDE; THROMBIN GENERATION; FACTOR-V; PROSTACYCLIN; STORAGE; CGMP; COLLAGEN; ASPIRIN; CELLS; ASSAY AB Refrigeration of platelets (4 degrees C) provides the possibility of improving transfusion practice over the current standard-of-care, room temperature (RT) storage. However, the increased level of platelet activation observed at 4 degrees C in vitro is cause for concern of uncontrolled thrombosis in vivo. In this study, we assessed the safety of 4 degrees C-stored platelets by evaluating their response to physiologic inhibitors prostacyclin (PGI(2)) and nitric oxide (NO). Apheresis platelets were collected from healthy donors (n=4) and tested on Day 1 (fresh) or Day 5 (RT- and 4 degrees C-stored) after treatment with PGI(2) and NO or not for: thrombin generation; factor V (FV) activity; intracellular free calcium, cAMP and cGMP; ATP release; TRAP-induced activation; aggregation to ADP, collagen, and TRAP, and adhesion to collagen under arterial flow. Data were analyzed using two-way ANOVA and post-hoc Tukey test for multiple comparisons, with significance set at P<0.05. Treatment with inhibitors increased intracellular cAMP and cGMP levels in fresh and stored platelets. Thrombin generation was significantly accelerated in stored platelets consistent with increased factor V levels, PS exposure, CD62P expression, intracellular free calcium, and ATP release. While treatment with inhibitors did not attenuate thrombin generation in stored platelets, activation, aggregation, and adhesion responses were inhibited by both PGI(2) and NO in 4 degrees C-stored platelets. In contrast, though RT-stored platelets were activated, they did not adhere or aggregate in response to agonists. Thus, refrigerated platelets maintain their intracellular machinery, are responsive to agonists and platelet function inhibitors, and perform hemostatically better than RT-stored platelets.

Cutaneous leishmaniasis (CL) is the most common form of this disease, and CL infections often result in serious skin lesions and scars. CL remains a public health problem in many endemic countries worldwide because of the absence of effective, safe, and cost-effective drugs for treatment. One of the strategies we chose to use to find novel chemical entities worthy of further development as antileishmanials involved screening synthetic and natural products libraries. In our study, we developed a Leishmania major intracellular amastigote assay that uses the activity of luciferase as a measure of parasite proliferation and used this assay to screen a collection of 400 compounds obtained from Medicines for Malaria Venture (MMV) for their antileishmanial activity. Our results showed that 14 compounds identified by MMV as antimalarial drugs have antileishmanial activity and can potentially be optimized for CL drug development.

High performance liquid chromatography electron spray tandem mass spectrometry was used for organic analysis and fluoride was measured using a fluoride-specific electrode. PFOA pseudo-1st order transformation rates (k(1,PFOA)) increased with increasing temperature (half-lives from 0.1 to 7 d for 60 to 30 degrees C) sequentially removing CF2 groups ('unzipping') to shorter chain perfluoroalkyl carboxylic acids (PFCAs) and F. At 50 degrees C, a 5-fold increase in S2O82- led to a 5-fold increase in k(1,PFOA) after which self-scavenging by sulfate radicals decreased the relative rate of increase with more S2O82-. Benzene, toluene, ethylbenzene and xylene did not affect k(1,PFOA) even at 40 times higher molar concentrations than PFOA. A modeling approach to explore pathways strongly supported that for 6:2 FTSA, both the ethyl linkage and CF2-CH2 bond of 6:2 FTSA oxidize simultaneously, resulting in a ratio of similar to 25/75 PFHpA/PFHxA. The effectiveness of heat-activated S2O82- on PFOA oxidation was reduced in a soil slurry; therefore, repeated persulfate injections are required to efficiently achieve complete oxidation in the field. However, PFOS remained unaltered even at higher activation temperatures, thus limiting the sole use of heat-activated persulfate for perfluoroalkyl substances removal in the field.

TI Aquapheresis Versus Intravenous Diuretics and Hospitalizations for Heart Failure SO JACC-HEART FAILURE LA English DT Article DE aquapheresis; congestion; fluid overload; heart failure; hospitalizations; loop diuretics; worsening renal function ID CONTINUOUS ULTRAFILTRATION; CARDIORENAL SYNDROME; TRIAL; FLUID AB OBJECTIVES The AVOID-HF (Aquapheresis versus Intravenous Diuretics and Hospitalization for Heart Failure) trial tested the hypothesis that patients hospitalized for HF treated with adjustable ultrafiltration (AUF) would have a longer time to first HF event within 90 days after hospital discharge than those receiving adjustable intravenous loop diuretics (ALD). BACKGROUND Congestion in hospitalized heart failure (HF) patients portends unfavorable outcomes. METHODS The AVOID-HF trial, designed as a multicenter, 1-to-1 randomized study of 810 hospitalized HF patients, was terminated unilaterally and prematurely by the sponsor (Baxter Healthcare, Deerfield, Illinois) after enrollment of 224 patients (27.5%). Aquadex FlexFlow System (Baxter Healthcare) was used for AUF. A Clinical Events Committee, blinded to the randomized treatment, adjudicated whether 90-day events were due to HF. RESULTS A total of 110 patients were randomized to AUF and 114 to ALD. Baseline characteristics were similar. Estimated days to first HF event for the AUF and ALD group were, respectively, 62 and 34 (p = 0.106). At 30 days, compared with the ALD group, the AUF group had fewer HF and cardiovascular events. Renal function changes were similar. More AUF patients experienced an adverse effect of special interest (p = 0.018) and a serious study product-related adverse event (p = 0.026). The 90-day mortality was similar. CONCLUSIONS Compared with the ALD group, the AUF group trended toward a longer time to first HF event within 90 days and fewer HF and cardiovascular events. More patients in the AUF group experienced special interest or serious product-related adverse event. Due to the trial's untimely termination, additional AUF investigation is warranted.

Philip TI Altered Appetite-Mediating Hormone Concentrations Precede Compensatory Overeating After Severe, Short-Term Energy Deprivation in Healthy Adults SO JOURNAL OF NUTRITION LA English DT Article DE calorie restriction; energy density; satiety; weight loss; gut hormone; intermittent fasting; energy balance ID GLUCAGON-LIKE PEPTIDE-1; FOOD-INTAKE; WEIGHT-LOSS; BODY-WEIGHT; OBESE MEN; DIETARY RESTRICTION; INTAKE RESPONSES; GHRELIN LEVELS; CENTRAL LEPTIN; EATING RATE AB Background: Adaptive responses of appetite-mediating hormones to negative energy balance are thought to contribute to a counterregulatory response that drives weight regain, but they have not been studied while controlling for reduced diet volume. Objective: In this secondary analysis, we aimed to determine the effects of short-term, severe energy deprivation (ED) on appetite and appetite-mediating hormone concentrations. Methods: Twenty-one adults with a mean +/- SD age of 21 +/- 3 y and body mass index of 25 +/- 3 kg/m(2) consumed isovolumetric diets provided over separate 48-h periods while increasing habitual energy expenditure by 1683 +/- 329 kcal/d through light- and moderate-intensity exercise. Energy intake was matched to energy expenditure to maintain energy balance (EB) (-44 +/- 92 kcal/d) or was <10% of energy expenditure to generate a 3696 +/- 742-kcal/d energy deficit. Postprandial appetite, glucose, insulin, acyl ghrelin, peptide YY, pancreatic polypeptide (PP), and glucagon-like peptide-1 (GLP-1) responses and ad libitum energy intake were measured as secondary outcomes after both experimental periods. Results: Fasting insulin (-56% +/- 42%) and acyl ghrelin (-60% +/- 17%) concentrations decreased during ED but not during EB (condition-by-time interaction; P-interaction <= 0.01), whereas fasting leptin concentrations decreased more during ED compared with during EB (-47% +/- 27% compared with 20% +/- 27%; P-interaction = 0.05). Postprandial insulin (57% +/- 63%; P < 0.001), GLP-1 (14% +/- 28%; P = 0.04), and PP (54% +/- 52%; P < 0.001) areas under the curve (AUCs) were higher, whereas the acyl ghrelin AUC was lower (-56% +/- 13%; P < 0.001) after ED compared with after EB. After ED, self-rated appetite was greater, and ad libitum energy intake was 811 kcal/36 h (95% CI: 184, 1439 kcal/36 h) higher relative to after EB (P = 0.01). Conclusions: Short-term, severe ED suppressed acyl ghrelin concentrations and increased postprandial anorexigenic hormone concentrations. These effects preceded compensatory overeating, suggesting that in adults without obesity, altered sensitivity to appetite-mediating hormones may contribute to an adaptive counterregulatory response during the initial stages of negative EB. This trial was registered at clinicaltrials.gov as NCT01603550. C1 [O'Connor, Kristie L.; Scisco, Jenna L.; Smith, Tracey J.; Young, Andrew J.; Montain, Scott J.; Lieberman, Harris R.; Karl, J.

TI Breast Milk Protects Against Gastrointestinal Symptoms in Infants at High Risk for Autism During Early Development SO JOURNAL OF PEDIATRIC GASTROENTEROLOGY AND NUTRITION LA English DT Article DE abdominal discomfort/pain; breast milk; breast-feeding; constipation; pervasive developmental disorder ID SPECTRUM DISORDERS; INTESTINAL PERMEABILITY; NECROTIZING ENTEROCOLITIS; MUCOSAL INJURY; FATTY-ACIDS; OLEIC-ACID; CHILDREN; MUCUS; INDIVIDUALS; POPULATION AB Objectives: Parents of children with autism spectrum disorders (ASDs) often report gastrointestinal (GI) dysfunction in their children. The objectives of the present study were to determine whether infants at high risk for developing ASD (ie, siblings of children diagnosed as having ASD) show greater prevalence of GI problems and whether this prevalence is associated with diet and age at weaning from breast milk. Methods:Using questionnaires, diet history and GI problems were tracked prospectively and retrospectively in 57 high-risk infants and for comparison in 114 low-risk infants (infants from families without ASD history). Results: In low-risk infants, prevalence of GI symptoms, in aggregate, did not vary with diet or age of weaning. By contrast, high-risk infants with GI symptoms were weaned earlier than those without symptoms (P<0.04), and high-risk infants showed greater prevalence of GI symptoms, in aggregate, on a no breast milk diet than on an exclusive breast milk diet (P<0.017). Constipation, in particular, was more prevalent in high-risk infants compared with low-risk infants (P=0.01), especially on a no breast milk diet (P=0.002). High-risk infants who completed weaning earlier than 6 months showed greater prevalence of constipation (P=0.001) and abdominal distress (P=0.004) than those fully weaned after 6 months. Conclusions:The greater prevalence of GI symptoms in high-risk infants suggests that GI dysfunction during early infant development may be a part of the ASD endophenotype. Late weaning and exclusive breast milk were associated with protection against GI symptoms in high-risk infants.

Recent progress in the direct conversion of light into photocurrent has been well documented using Photosystem I. In plants, PSI consists of a core complex and multiple light-harvesting complexes, denoted LHCI and LHCII. Most of the methods for isolating PSI from plants involve a selective, detergent solubilization from thylakoids followed by sucrose gradient density centrifugation. These processes isolate one variant of PSI with a specific ratio of Chl:P-700. In this study, we have developed a simple and potentially scalable method for isolating multiple PSI variants using Hydroxyapatite chromatography, which has been well documented in other Photosystem I isolation protocols. By varying the wash conditions, we show that it is possible to change the Chl:P-700 ratios. These different PSI complexes were cast into a PSI-Nafion-osmium polymer film that enabled their photoactivity to be measured. Photocurrent increases nearly 400 % between highly washed and untreated solutions based on equal chlorophyll content. Importantly, the mild washing conditions remove peripheral Chl and some LHCI without inhibiting the photochemical activity of PSI as suggested by SDS-PAGE analysis. This result could indicate that more P-700 could be loaded per surface area for biohybrid devices. Compared with other PSI isolations, this protocol also allows isolation of multiple PSI variants without loss of photochemical activity. C1 [Carter, J. Ridge; Witt, T.

For non-planar molecules like phosphole, aromaticity of their planar transition states was also studied, and a special modification of ASE index was proposed to that end. It was found that the presence of two lone pairs is generally preferable for aromaticity of all heterocycles except CPD and silolyl dianions. Heterocycles with group 16 heteroatoms have consistently lower aromaticity compared to other groups. A lot of structures should be classified as moderate aromatic and non-aromatic. Energies of out-of-plane deformation do not correlate with other indices studied, but reveal the same qualitative trends. Generally, aromaticity of five-membered monoheterocycles depends strongly on both heteroatom type and number of lone pairs on it.

In this study, we applied the QSAR/QSPR models previously developed by our group for virtual screening of energetic compounds, their precursors and other compounds containing nitro groups. To make predictions on the environmental impact of nitro compounds, we analyzed the trends in the change of the experimentally obtained and QSAR/QSPR-predicted values of aqueous solubility, lipophilicity, Ames mutagenicity, bioavailability, blood-brain barrier penetration, aquatic toxicity on T. pyriformis and acute oral toxicity on rats as a function of chemical structure of nitro compounds. All the models were developed using simplex descriptors in combination with random forest (RF) modeling techniques. We interpreted the possible environmental impact (different toxicological properties) in terms of dividing considered nitro compounds based on hydrophobic and hydrophilic characteristics and in terms of the influence of their molecular fragments that promote and interfere with toxicity. In particular, we found that, in general, the presence of amide or tertiary amine groups leads to an increase in toxicity. Also, it was predicted that compounds containing a NO2 group in the para-position of a benzene ring are more toxic than meta-isomers, which, in turn, are more toxic than ortho-isomers. In general, we concluded that hydrophobic nitroaromatic compounds, especially the ones with electron-accepting substituents, halogens and amino groups, are the most environmentally hazardous.

There are six known species of HCoV: HCoV-229E, HCoV-NL63, HCoV-HKU1, HCoV-OC43, MERS-CoV and SARS-HCoV. Although studies have shown evidence of global distribution of HCoVs, there is limited information on their presence and distribution in Kenya. Methods: HCoV strains that circulated in Kenya were retrospectively diagnosed and molecularly characterized. A total of 417 nasopharyngeal specimens obtained between January 2009 and December 2012 from around Kenya were analyzed by a real time RT-PCR using HCoV-specific primers. HCoV-positive specimens were subsequently inoculated onto monolayers of LL-CMK2 cells. The isolated viruses were characterized by RT-PCR amplification and sequencing of the partial polymerase (pol) gene. Results: The prevalence of HCoV infection was as follows: out of the 417 specimens, 35 (8.4 %) were positive for HCoV, comprising 10 (2.4 %) HCoV-NL63, 12 (2.9 %) HCoV-OC43, 9 (2.1 %) HCoV-HKU1, and 4 (1 %) HCoV-229E. The Kenyan HCoV strains displayed high sequence homology to the prototypes and contemporaneous strains. Evolution analysis showed that the Kenyan HCoV-OC43 and HCoV-NL63 isolates were under purifying selection. Phylogenetic evolutionary analyses confirmed the identities of three HCoV-HKU1, five HCoV-NL63, eight HCoV-OC43 and three HCoV-229E. Conclusions: There were yearly variations in the prevalence and circulation patterns of individual HCoVs in Kenya. This paper reports on the first molecular characterization of human Coronaviruses in Kenya, which play an important role in causing acute respiratory infections among children.

In doing so, we sought to develop models of behavior that would enable the identification of common cross-participant and cross-task EEG features. To accomplish this we had participants perform both simulated driving and guard duty tasks while we recorded their EEG. For each participant we developed models to estimate their behavioral performance during both tasks. Sequential forward floating selection was used to identify the montage of independent components for each model. Linear regression was then used on the combined power spectra from these independent components to generate a continuous estimate of behavior. Our results show that oscillatory processes, evidenced in EEG, can be used to successfully capture slow fluctuations in behavior in complex, multi-faceted tasks. The average correlation coefficients between the actual and estimated behavior was 0.548 +/- 0.117 and 0.701 +/- 0.154 for the driving and guard duty tasks respectively. Interestingly, through a simple clustering approach we were able to identify a number of common components, both neural and eye-movement related, across participants and tasks. We used these component clusters to quantify the relative influence of common versus participant-specific features in the models of behavior. These findings illustrate the potential for estimating complex behavioral dynamics from concurrent measures from EEG using a finite library of universal features. Published by Elsevier B.V.

Highly potent broadly neutralizing HIV-1 monoclonal antibodies (MAbs) can reduce plasma viremia when administered during chronic HIV-1 infection, but the therapeutic potential of these antibodies during acute infection is unknown. We tested the ability of HIV-1 envelope glycoprotein-specific broadly neutralizing MAbs to suppress acute simian-human immunodeficiency virus (SHIV) replication in rhesus macaques. Four groups of macaques were infected with SHIV-SF162P3 and received (i) the CD4-binding-site MAb VRC01; (ii) a combination of a more potent clonal relative of VRC01 (VRC07-523) and a V3 glycan-dependent MAb (PGT121); (iii) daily cART, all on day 10, just prior to expected peak plasma viremia; or (iv) no treatment. Daily cART was initiated 11 days after MAb administration and was continued for 13 weeks in all treated animals. Over a period of 11 days after a single administration, MAb treatment significantly reduced peak viremia, accelerated the decay slope, and reduced total viral replication compared to untreated controls. Proviral DNA in lymph node CD4 T cells was also diminished after treatment with the dual MAb. These data demonstrate the virological effect of potent MAbs and support future clinical trials that investigate HIV-1-neutralizing MAbs as adjunctive therapy with cART during acute HIV-1 infection.

Deep mutagenesis of haploid human cells was used to identify host factors required for RVFV infection. This screen identified a suite of enzymes involved in glycosaminoglycan (GAG) biogenesis and transport, including several components of the cis-oligomeric Golgi (COG) complex, one of the central components of Golgi complex trafficking. In addition, disruption of PTAR1 led to RVFV resistance as well as reduced heparan sulfate surface levels, consistent with recent observations that PTAR1-deficient cells exhibit altered Golgi complex morphology and glycosylation defects. A variety of biochemical and genetic approaches were utilized to show that both pathogenic and attenuated RVFV strains require GAGs for efficient infection on some, but not all, cell types, with the block to infection being at the level of virion attachment. Examination of other members of the Bunyaviridae family for GAG-dependent infection suggested that the interaction with GAGs is not universal among bunyaviruses, indicating that these viruses, as well as RVFV on certain cell types, employ additional unidentified virion attachment factors and/or receptors.

Data SourcesPubMed, Scopus, Embase, Google Scholar, Book Citation Index-Science, CINAHL, Conference Proceedings Citation Index-Science, The Cochrane Collaboration Databases, and Web of Science. Review MethodThe searches were performed from the first year of each database through March 5, 2015. ResultsFourteen studies about the prevalence of epiglottis collapse in obstructive sleep apnea (OSA) were found. Most involved drug-induced sleep endoscopy studies that indirectly reported their findings about epiglottis collapse. The data suggests that the prevalence of epiglottis collapse in OSA is higher than previously described. The epiglottis has been implicated in 12% of cases of snoring, and sound originating from it has a higher pitch than palatal snoring. Continuous positive pressure (CPAP) surgery and positional therapy in the treatment of epiglottis collapse were also considered. Lateral position of the head may reduce the frequency of epiglottis collapse. With regard to CPAP, available reports suggest that it may accentuate collapse of the epiglottis. Surgery may help reduce snoring in some patients with a lax epiglottis and improve OSA in patients undergoing multilevel surgery. ConclusionKnowledge regarding the role of the epiglottis in adult OSA and snoring patients is limited. The prevalence of this phenomenon in OSA seems to be greater than previously reported, and more research is needed to understand its role in OSA and the best way to treat it.

TI Quantitative Model of Sustained Physical Task Duration at Varying Altitudes SO MEDICINE AND SCIENCE IN SPORTS AND EXERCISE LA English DT Article DE HYPOXIA; HYPOBARIC HYPOXIA; ALGORITHM; ENDURANCE PERFORMANCE; SUBMAXIMAL EXERCISE; UNACCLIMATIZED LOWLANDERS ID SEA-LEVEL; ENDURANCE PERFORMANCE; EXERCISE PERFORMANCE; RUNNING PERFORMANCE; HYPOXIA; CAPACITY; EXPOSURE; RUNNERS; MEN AB Purpose: The objective of this study is to develop a quantitative model that can be used before ascent to altitude (ALT) to predict how much longer a sustained physical task would take for unacclimatized individuals in the early hours of exposure. Methods: Using multiple linear regression, we analyzed time-trial (TT) performance on 95 unacclimatized men (n = 83) and women (n = 12) at sea level (SL) and at an ALT ranging from 2500 to 4300 m. The TT was initiated within 4 h of ascent to ALT. The independent variables known before ascent were as follows: ALT, age, height, weight, sex, SL peak oxygen uptake, SL task duration time, and body mass index (BMI) classification (normal weight vs overweight). The dependent variable was the percent increase in TT duration from SL to ALT. Results: The most significant factor in the model was ALT (P = 0.0001), followed by BMI classification (P = 0.0009) and the interaction between BMI classification and ALT (P = 0.003). The model is as follows: percent increase in TT duration = [100 + e((-1.517+1.323 (ALT)+3.124 (BMI class)-0.769 (ALT) (BMI class))]. The percent increase in TT duration in overweight individuals was 129% greater than for normal-weight individuals at 3000 m. However, as ALT increased beyond 3000 m, the disparity between groups decreased until 4050 m where the percent increase in TT duration became greater for normal-weight individuals. Conclusions: This model provides the first quantitative estimates of the percent increase in sustained physical task duration during initial exposure to a wide range of elevations. Because only two easily obtainable factors are required as inputs for the model (ALT and BMI classification), this model can be used by many unacclimatized individuals to better plan their activities at ALT.

Little is known about how NGF elicits faster axon outgrowth or how growth cones integrate and transform signal input to motor output. Using cultured mouse dorsal root ganglion neurons, we found that myosin II (MII) is required for NGF to stimulate faster axon outgrowth. From experiments inducing loss or gain of function of MII, specific MII isoforms, and vinculin-dependent adhesion-cytoskeletal coupling, we determined that NGF causes decreased vinculin-dependent actomyosin restraint of microtubule advance. Inhibition of MII blocked NGF stimulation, indicating the central role of restraint in directed outgrowth. The restraint consists of myosin IIB- and IIA-dependent processes: retrograde actin network flow and transverse actin bundling, respectively. The processes differentially contribute on laminin-1 and fibronectin due to selective actin tethering to adhesions. On laminin-1, NGF induced greater vinculin-dependent adhesion-cytoskeletal coupling, which slowed retrograde actin network flow (i.e., it regulated the molecular clutch). On fibronectin, NGF caused inactivation of myosin IIA, which negatively regulated actin bundling. On both substrates, the result was the same: NGF-induced weakening of MII-dependent restraint led to dynamic microtubules entering the actin-rich periphery more frequently, giving rise to faster elongation.

TI Highly compliant shape memory polymer gels for tunable damping and reversible adhesion SO SMART MATERIALS AND STRUCTURES LA English DT Article DE shape memory polymer; reversible damping; polymer gel ID BIOMEDICAL APPLICATIONS; MECHANICAL-PROPERTIES; GRANULAR MEDIA; ACRYLIC-ACID; HYDROGELS; NETWORKS; BEHAVIOR; ROBOT; SURFACES; RHEOLOGY AB Materials that can dynamically change their properties to better adapt to the local environment have potential utility in robotics, aerospace, and coatings. For some of these applications, most notably robotics, it is advantageous for these responsive materials to be highly compliant in an effort to provide dynamic changes in adhesion and mechanical damping within a broad temperature operational environment. In this report, non-aqueous, highly compliant shape-memory polymer gels are developed by incorporating a low density of chemical cross-links into a physically cross-linked thermoplastic elastomer gel. Chemical cross-linkers were evaluated by varying there size and degree of functionality to determine the impact on the mechanical and adhesive properties. As a result of the chemical cross-linking, the gels exhibit modulus plateaus around room temperature and at elevated temperatures above 100 degrees C, where the thermoplastic elastomer gel typically melts. The materials were designed so that moduli in the plateaued regions were above and below the Dahlquist criteria of 4 x 10(4) Pa, respectively, where materials with a modulus below this value typically exhibit an increase in adhesion. The shape memory polymer gels were also integrated into fiber-reinforced composites to determine the temperature-dependent changes in mechanical damping. It is anticipated that this work will provide insight into materials design to provide dynamic changes in adhesion and damping to improve robotic appendage manipulation and platform mobility.

TI A simple nonradioactive method for the determination of the binding affinities of antibodies induced by hapten bioconjugates for drugs of abuse SO ANALYTICAL AND BIOANALYTICAL CHEMISTRY LA English DT Article DE Heroinhapten; Competition ELISA; Equilibrium dialysis; UPLC/MS/MS; Apparent dissociation constant (K-d); Antibody affinity ID LINKED IMMUNOSORBENT ASSAY; SIMPLE CHEMICAL-COMPOUNDS; MINIMAL CROSS-REACTIVITY; DIACETYLMORPHINE HEROIN; MONOCLONAL-ANTIBODIES; MASS-SPECTROMETRY; MORPHINE; RADIOIMMUNOASSAY; VACCINE; SPECIFICITY AB The accurate analytical measurement of binding affinities of polyclonal antibody in sera to heroin, 6-acetylmorphine (6-AM), and morphine has been a challenging task. A simple nonradioactive method that uses deuterium-labeled drug tracers and equilibrium dialysis (ED) combined with ultra performance liquid chromatography/tandem mass spectrometry (UPLC/MS/MS) to measure the apparent dissociation constant (K (d)) of antibodies to 6-AM and morphine is described. The method can readily detect antibodies with K (d) in the low nanomolar range. Since heroin is rapidly degraded in sera, esterase inhibitors were included in the assay, greatly reducing heroin hydrolysis. MS/MS detection directly measured the heroin in the assay after overnight ED, thereby allowing the quantitation of % bound heroin in lieu of K (d) as an alternative measurement to assess heroin binding to polyclonal antibody sera. This is the first report that utilizes a solution-based assay to quantify heroin-antibody binding without being confounded by the presence of 6-AM and morphine and to measure K (d) of polyclonal antibody to 6-AM. Hapten surrogates 6-AcMorHap, 6-PrOxyHap, MorHap, DiAmHap, and DiPrOxyHap coupled to tetanus toxoid (TT) were used to generate high affinity antibodies to heroin, 6-AM, and morphine. In comparison to competition ED-UPLC/MS/MS which gave K (d) values in the nanomolar range, the commonly used competition enzyme-linked immunosorbent assay (ELISA) measured the 50 % inhibition concentration (IC50) values in the micromolar range. Despite the differences in K (d) and IC50 values, similar trends in affinities of hapten antibodies to heroin, 6-AM, and morphine were observed by both methods. Competition ED-UPLC/MS/MS revealed that among the five TT-hapten bioconjugates, TT-6-AcMorHap and TT-6-PrOxyHap induced antibodies that bound heroin, 6-AM, and morphine. In contrast, TT-MorHap induced antibodies that poorly bound heroin, while TT-DiAmHap and TT-DiPrOxyHap induced antibodies either did not bind or poorly bound to heroin, 6-AM, and morphine. This simple and nonradioactive method can be extended to other platforms, such as oxycodone, cocaine, nicotine, and methamphetamine for the selection of the lead hapten design during substance abuse vaccine development.

In particular, we measured optical, acoustic and photoelastic parameters of the following alloy compounds: germanium-selenium-tellurium (Ge-Se- Te), germanium-selenium-sulfur-tellurium (Ge-Se-S-Te), germanium-silicon-tellurium (Ge-Si-Te) and silicon-tellurium (Si-Te). Like single-crystal tellurium, the glasses demonstrate good acousto-optic (AO) diffraction efficiency and have reasonable optical transparency in a wide spectral region covering wavelengths from 1.5 to 20 mu m. The optical, acoustic and photoelastic properties of the tellurium-based compounds were measured using infrared lamp sources of radiation as well as He-Ne and CO2 lasers. In this paper, we report on the optical, acoustic and photoelastic parameters of a selection of these compounds and discuss the advantages and disadvantages of using these glasses for AO device applications. We also present the measured characteristics of an AO cell fabricated in a Si20Te80 glass material which exhibited high optical uniformity and long-term chemical stability. C1 [Voloshinov, V.

Misdiagnosis frequently results in ineffective treatment. We investigated the utility of a biomarker panel as a diagnostic test for BD. Methods and findings: We performed a meta-analysis of eight case-control studies to define a diagnostic biomarker panel for BD. After validating the panel on established BD patients, we applied it to undiagnosed BD patients. We analysed 249 BD, 122 pre-diagnostic BD, 75 pre-diagnostic schizophrenia and 90 first onset major depression disorder (MDD) patients and 371 controls. The biomarker panel was identified using ten-fold cross-validation with lasso regression applied to the 87 analytes available across the meta-analysis studies. We identified 20 protein analytes with excellent predictive performance [area under the curve (AUC) >= 0.90]. Importantly, the panel had a good predictive performance (AUC 0.84) to differentiate 12 misdiagnosed BD patients from 90 first onset MDD patients, and a fair to good predictive performance (AUC 0.79) to differentiate between 110 pre-diagnostic BD patients and 184 controls. We also demonstrated the disease specificity of the panel. Conclusions: An early and accurate diagnosis has the potential to delay or even prevent the onset of BD. This study demonstrates the potential utility of a biomarker panel as a diagnostic test for BD. (C) 2015 The Authors. Published by Elsevier Inc.

Before transcriptomic information can be used in monitoring and risk assessment, it is necessary to determine its reproducibility and detect key steps impacting the reliable identification of differentially expressed genes. A custom 15K-probe microarray was used to conduct transcriptomics analyses across six laboratories with estuarine amphipods exposed to cyfluthrin-spiked or control sediments (10 days). Two sample types were generated, one consisted of total RNA extracts (Ex) from exposed and control samples (extracted by one laboratory) and the other consisted of exposed and control whole body amphipods (WB) from which each laboratory extracted RNA. Our findings indicate that gene expression microarray results are repeatable. Differentially expressed data had a higher degree of repeatability across all laboratories in samples with similar RNA quality (Ex) when compared to WB samples with more variable RNA quality. Despite such variability a subset of genes were consistently identified as differentially expressed across all laboratories and sample types. We found that the differences among the individual laboratory results can be attributed to several factors including RNA quality and technical expertise, but the overall results can be improved by following consistent protocols and with appropriate training.

Data on NTO fate and transport is needed to determine its environmental behavior and potential for groundwater contamination. We conducted a series of kinetic and equilibrium batch experiments to characterize the fate of NTO in soils and the effect of soil geochemical properties on NTO-soil interactions. A set of experiments was also conducted using sterilized soils to evaluate the contribution of biodegradation to NTO attenuation. Measured pH values for NTO solutions decreased from 5.98+/-0.13 to 3.50+/-0.06 with increase in NTO concentration from 0.78 to 100 mg L-1. Conversely, the pH of soil suspensions was not significantly affected by NTO in this concentration range. NTO experienced minimal adsorption, with measured adsorption coefficients being less than 1 cm(3) g(-1) for all studied soils. There was a highly significant inverse relationship between the measured NTO adsorption coefficients and soil pH (P = 0.00011), indicating the role of NTO and soil charge in adsorption processes. In kinetic experiments, 1st order transformation rate constant estimates ranged between 0.0004 h(-1) and 0.0142 h(-1) (equivalent to half-lives of 72 and 2 d, respectively), and correlated positively with organic carbon in the soil. Total attenuation of NTO was higher in untreated versus sterilized samples, suggesting that NTO was being biodegraded. The information presented herein can be used to help evaluate NTO potential for natural attenuation in soils. (C) 2015 Elsevier Ltd. All rights reserved.

TI Costs and Consequences: Hepatitis C Seroprevalence in the Military and Its Impact on Potential Screening Strategies SO HEPATOLOGY LA English DT Article ID TASK-FORCE RECOMMENDATION; VIRUS-INFECTION; UNITED-STATES; WHOLE-BLOOD; SOFOSBUVIR; REGIMENS AB Knowledge of the contemporary epidemiology of hepatitis C viral (HCV) infection among military personnel can inform potential Department of Defense screening policy. HCV infection status at the time of accession and following deployment was determined by evaluating reposed serum from 10,000 service members recently deployed to combat operations in Iraq and Afghanistan in the period 2007-2010. A cost model was developed from the perspective of the Department of Defense for a military applicant screening program. Return on investment was based on comparison between screening program costs and potential treatment costs avoided. The prevalence of HCV antibody-positive and chronic HCV infection at accession among younger recently deployed military personnel born after 1965 was 0.98/1000 (95% confidence interval 0.45-1.85) and 0.43/1000 (95% confidence interval 0.12-1.11), respectively. Among these, service-related incidence was low; 64% of infections were present at the time of accession. With no screening, the cost to the Department of Defense of treating the estimated 93 cases of chronic HCV cases from a single year's accession cohort was $9.3 million. Screening with the HCV antibody test followed by the nucleic acid test for confirmation yielded a net annual savings and a $3.1 million dollar advantage over not screening. Conclusions: Applicant screening will reduce chronic HCV infection in the force, result in a small system costs savings, and decrease the threat of transfusion-transmitted HCV infection in the battlefield blood supply and may lead to earlier diagnosis and linkage to care; initiation of an applicant screening program will require ongoing evaluation that considers changes in the treatment cost and practice landscape, screening options, and the epidemiology of HCV in the applicant/accession and overall force populations.

TI Bridging atomistic simulations and experiments via virtual diffraction: understanding homophase grain boundary and heterophase interface structures SO JOURNAL OF MATERIALS SCIENCE LA English DT Article ID STRUCTURE-ENERGY CORRELATION; X-RAY-DIFFRACTION; FCC METALS; MOLECULAR-DYNAMICS; TILT BOUNDARIES; GOLD; ALUMINUM; ANGLE; DEFORMATION; NUCLEATION AB Virtual diffraction is a computational technique that enables a synergistic coupling between experiments and atomistic simulations, which can help to elucidate nanoscale structure-property relationships. The research objective herein is to highlight recent advances in the use of virtual diffraction as a method to study the geometry and structure of homophase grain boundaries and heterophase interfaces with direct experimental validation. Virtual selected area diffraction patterns for two types of boundaries-homophase Al twist grain boundaries and heterophase Al2O3/Al interfaces-are created without a priori assumption of the periodic interface structure by computing diffraction intensities across high-resolution, 3-D reciprocal space meshes. In this work, computed diffraction patterns clearly identify Al grain boundary misorientation angles, reveal subsidiary peaks created by the dislocation arrays within select Al grain boundaries, and allow experimental validation of the minimum energy orientation relationship for the Al2O3/Al interface. Due to its advanced implementation, virtual diffraction characterization used throughout this work can be easily extended providing routes for similar analysis and experimental validation of atomistic simulations.

TI Mobility algorithm evaluation using a consolidated database developed for wheeled vehicles operating on dry sands SO JOURNAL OF TERRAMECHANICS LA English DT Article DE Mobility; Sand; Drawbar pull; Motion resistance; Sinkage; Vehicle Terrain Interface (VTI); Database AB A substantial number of laboratory and field tests have been conducted to assess performance of various wheel designs in loose soils. However, there is no consolidated database which includes data from several sources. In this study, a consolidated database was created on tests conducted with wheeled vehicles operating in loose dry sand to evaluate existing soil mobility algorithms. The database included wheels of different diameters, widths, heights, and inflation pressures, operating under varying loading conditions. Nine technical reports were identified containing 5253 records, based on existing archives of laboratory and field tests of wheels operating in loose soils. The database structure was assembled to include traction performance parameters such as drawbar pull, torque, traction, motion resistance, sinkage, and wheel slip. Once developed, the database was used to evaluate and support validation of closed form solutions for these variables in the Vehicle Terrain Interface (VTI) model. The correlation between predicted and measured traction performance parameters was evaluated. Comparison of the predicted versus measured performance parameters suggests that the closed form solutions within the VTI model are functional but can be further improved to provide more accurate predictions for off-road vehicle performance.

Previous results and literature indicated higher reactor temperatures to yield superior results. The well-insulated reactor developed incorporated elements of the low temperature reactor design. The syngas obtained was of better quality in terms of gas species component present and the syngas heating value than that reported previously from a non-catalytic reformer. The syngas composition consisted of 19.2% hydrogen and 20.8% carbon monoxide and these values are higher than the previously reported data. Lower series of hydrocarbons (acetylene and propane) were only detected in trace amounts (less than 15 ppm). Elevated reactor temperatures promoted the dissociation of lower series of hydrocarbons (methane, acetylene, and ethylene), which provided additional syngas formation. The gas species concentrations obtained approached that of catalytic reforming. Flame regime was determined through numerical diagnostics. As reaction regime became less distributed with higher injection temperature, reformate quality was adversely impacted. The mitigation of thermal losses from the well-insulated reactor promoted superior reformer efficiency by allowing the reactor to achieve conditions not possible in low temperature reactors.

TI Band structure modulation in MoS2 multilayers and heterostructures through electric field and strain SO COMPUTATIONAL MATERIALS SCIENCE LA English DT Article DE MoS2; Heterostructures; Electric field; Band gap ID TRANSITION-METAL DICHALCOGENIDES; MONOLAYER MOS2 AB We use density functional theory to investigate the effect of finite external electric fields along with strain on the electronic structure of MoS2 multilayers and heterostructures composed of MoS2/MoSe2/MoS2 and MoS2/WS2/MoS2. We find that the presence of an electric field decreases the values of both direct and indirect band gaps, in agreement with earlier works. However, when either compressive or tensile strain is applied to the system the strength of the coupling between the electric field and direct band gap is increased while the coupling strength between the electric field and the indirect band gap is decreased. In contrast, in the heterostructures the coupling with the direct band gap remains unchanged while the coupling with indirect band gap is decreased. Taken together, these results show rich behavior of the electric field effects in MoS2 multilayers and heterostructures. (C) 2015 Elsevier B.V. All rights reserved.

TI A regression method for estimating performance in a rapid serial visual presentation target detection task SO JOURNAL OF NEUROSCIENCE METHODS LA English DT Article DE RSVP; Hit rate; False alarm rate; Response time; Simulation ID COUPLED COMPUTER VISION; ATTENTIONAL BLINK; IDENTIFICATION; CLASSIFICATION; RECOGNITION; PICTURES AB Background: Estimating target detection performance in the rapid serial visual presentation (RSVP) target detection paradigm can be challenging when the inter-stimulus interval is small relative to the variability in human response time. The challenge arises because assigning a particular response to the correct image cannot be done with certainty. Existing solutions to this challenge establish a heuristic for assigning responses to images and thereby determining which responses are hits and which are false alarms. New method: We developed a regression-based method for estimating hit rate and false alarm rate that corrects for expected errors in a likelihood-based assignment of responses to stimuli. Results: Simulations show that this regression method results in an unbiased and accurate estimate of target detection performance. Comparison with existing methods: The regression method had lower estimation error compared to three existing methods, and in contrast to the existing methods, the errors made by the regression method do not depend strongly on the true values of hit rate and false alarm rate. The most commonly used existing method performed well when simulated performance was nearly perfect, but not when behavioral error rates increased. Conclusions: Based on its better estimation of hit rate and false alarm rate, the regression method proposed here would seem the best choice when estimating the hit rate and false alarm rate is the primary interest.

Male Sprague-Dawley rats (300-350 g) were exposed to 9000, 20 000, 23 000, 26 000, 30 000 or 35 000 ppm of ammonia for 20 min in a custom head-out exposure system. The exposure atmosphere, which attained steady state within 3 min for all ammonia concentrations, was monitored and verified using a Fourier transform infrared spectroscopy (FTIR) gas analyzer. Animals exposed to ammonia resulted in dose-dependent increases in observed signs of intoxication, including increased chewing and licking, ocular irritation, salivation, lacrimation, oronasal secretion and labored breathing. The LCt(50) of ammonia within this head-out inhalation exposure model was determined by probit analysis to be 23 672 ppm (16 489 mg/m(3)) for the 20 min exposure in male rats. Exposure to 20 000 or 23 000 ppm of ammonia resulted in significant body weight loss 24-h post-exposure. Lung edema increased in all ammonia-exposed animal groups and was significant following exposure to 9000 ppm. Bronchoalveolar fluid (BALF) protein concentrations significantly increased following exposure to 20 000 or 23 000 ppm of ammonia in comparison to controls. BAL cell (BALC) death and total cell counts increased in animals exposed to 20 000 or 23 000 ppm of ammonia in comparison to controls. Differential cell counts of white blood cells, neutrophils and platelets from blood and BALF were significantly increased following exposure to 23 000 ppm of ammonia. The following studies describe the validation of a head-out inhalation exposure model for the determination of acute ammonia-induced toxicity; this model will be used for the development and evaluation of potential therapies that provide protection against respiratory and systemic toxicological effects.

TI Dislocation evolution and peak spall strengths in single crystal and nanocrystalline Cu SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID VOID GROWTH; DUCTILE FRACTURE; MAXIMUM STRENGTH; DYNAMIC FAILURE; STRAIN-RATE; COPPER; NUCLEATION; BEHAVIOR; METALS; SIMULATION AB The dynamic evolution and interaction of defects under the conditions of shock loading in single crystal and nanocrystalline Cu are investigated using a series of large-scale molecular dynamics simulations for an impact velocity of 1 km/s. Four stages of defect evolution are identified during shock simulations that result in deformation and failure. These stages correspond to: the initial shock compression (I); the propagation of the compression wave (II); the propagation and interaction of the reflected tensile wave (III); and the nucleation, growth, and coalescence of voids (IV). The effect of the microstructure on the evolution of defect densities during these four stages is characterized and quantified for single crystal Cu as well as nanocrystalline Cu with an average grain size of 6 nm, 10 nm, 13 nm, 16 nm, 20 nm, and 30 nm. The evolution of twin densities during the shock propagation is observed to vary with the grain size of the system and affects the spall strength of the metal. The grain sizes of 6 nm and 16 nm are observed to have peak values for the twin densities and a spall strength that is comparable with the single crystal Cu. (C) 2016 AIP Publishing LLC.

TI Fish connectivity mapping: linking chemical stressors by their mechanisms of action-driven transcriptomic profiles SO BMC GENOMICS LA English DT Article DE Fish; Gene expression profiles; Connectivity mapping ID MINNOWS PIMEPHALES-PROMELAS; GENE-EXPRESSION SIGNATURES; BISPHENOL-A; ANDROGEN RECEPTOR; RISK-ASSESSMENT; HYDROCARBON RECEPTOR; MOLECULAR TARGET; ECOLOGICAL RISK; FATHEAD MINNOW; ZEBRAFISH AB Background: A very large and rapidly growing collection of transcriptomic profiles in public repositories is potentially of great value to developing data-driven bioinformatics applications for toxicology/ecotoxicology. Modeled on human connectivity mapping (Cmap) in biomedical research, this study was undertaken to investigate the utility of an analogous Cmap approach in ecotoxicology. Over 3500 zebrafish (Danio rerio) and fathead minnow (Pimephales promelas) transcriptomic profiles, each associated with one of several dozen chemical treatment conditions, were compiled into three distinct collections of rank-ordered gene lists (ROGLs) by species and microarray platforms. Individual query signatures, each consisting of multiple gene probes differentially expressed in a chemical condition, were used to interrogate the reference ROGLs. Results: Informative connections were established at high success rates within species when, as defined by their mechanisms of action (MOAs), both query signatures and ROGLs were associated with the same or similar chemicals. Thus, a simple query signature functioned effectively as an exposure biomarker without need for a time-consuming process of development and validation. More importantly, a large reference database of ROGLs also enabled a query signature to cross-interrogate other chemical conditions with overlapping MOAs, leading to novel groupings and subgroupings of seemingly unrelated chemicals at a finer resolution. This approach confirmed the identities of several estrogenic chemicals, as well as a polycyclic aromatic hydrocarbon and a neuro-toxin, in the largely uncharacterized water samples near several waste water treatment plants, and thus demonstrates its future potential utility in real world applications. Conclusions: The power of Cmap should grow as chemical coverages of ROGLs increase, making it a framework easily scalable in the future. The feasibility of toxicity extrapolation across fish species using Cmap needs more study, however, as more gene expression profiles linked to chemical conditions common to multiple fish species are needed.

Herein, we report a bridging coligand strategy to prepare new types of polyMOFs, demonstrating that polyMOFs are compatible with additional MOF architectures besides that of the earlier reported IRMOF-1 type polyMOF. Gas sorption studies revealed that these polyMOF materials exhibited relatively high CO2 sorption but very low N-2 sorption, making them promising materials for CO2/N-2 separations. Moreover, these polyMOFs demonstrated exceptional water stability attributed to the hydrophobicity of polymer ligands as well as the cross-linking of the polymer chains within the MOF.

In addition, a microstructure-sensitive fatigue model is employed to further elucidate cause-effect relationships. Experimental strain-controlled fatigue testing revealed an increase in the cyclic strain hardening and the number-of cycles to failure as the tool rotational speed was increased. At higher applied strain amplitudes (> 0.3%), the corresponding stress amplitude increased and the plastic strain amplitude decreased, as the number of cycles increased. However, at 0.2% strain amplitude, the plastic strain decreased until it was almost negligible. Inspection of the hysteresis loops demonstrated that at low strain amplitudes, there was an initial stage of strain hardening that increased until it reached a maximum strain hardening level, afterwards a nearly perfect elastic behavior was observed. Under fully-reversed fatigue loading, all samples failed at the region between the heat-affected and thermomechnically-affected zones. Inspection of the fractured surfaces under scanning electron microscopy revealed that the cracks initiated at either the crown or the root surface of the weld, and from secondary intermetallic particles located near the free surface of the weld. Lastly, a microstructure-sensitive multistage fatigue model was employed to correlate the fatigue life of the dissimilar FSW of AA6061-to-AA7050 considering microstructural features such as grain size, intermetallic particles and mechanical properties.

In this work, the effect of lithium salt concentration in 1,2-dimethoxyethane (DME)-based electrolytes on the cycling stability of Li-O-2 batteries is investigated systematically. Cells with highly concentrated electrolyte demonstrate greatly enhanced cycling stability under both full discharge/charge (2.0-4.5 V vs Li/Li+) and the capacity-limited (at 1000 mAh g(-1)) conditions. These cells also exhibit much less reaction residue on the charged air-electrode surface and much less corrosion of the Li-metal anode. Density functional theory calculations are used to calculate molecular orbital energies of the electrolyte components and Gibbs activation energy barriers for the superoxide radical anion in the DME solvent and Li+-(DME) (n) solvates. In a highly concentrated electrolyte, all DME molecules are coordinated with salt cations, and the C-H bond scission of the DME molecule becomes more difficult. Therefore, the decomposition of the highly concentrated electrolyte can be mitigated, and both air cathodes and Li-metal anodes exhibit much better reversibility, resulting in improved cyclability of Li-O-2 batteries.

The material is composed of well dispersed silver nanoparticles confined within the mesochannels of aluminum doped MCM-41 nanoparticles. With an average initial desulfurization capacity of 15 mg S.g(-1), 79% desulfurization capacity is retained after six cycles for the removal of dibenzothiophene from n-decane. The addition of intraframework aluminum to form a mesoporous aluminosilicate nanoparticle (MASN) aids in the retention and dispersion of silver ions within the mesochannels (Ag-MASN). The nanoparticles are subsequently reduced by glow discharge plasma treatment in argon (PT-Ag-MASN). The size dispersion, surface area, and structural integrity were characterized by scanning electron microscopy, annular dark-field scanning transmission electron microscopy (ADF-STEM), nitrogen adsorption analysis (BET), and powder X-ray diffraction. Silver nanoparticle formation within the mesochannels of MASN was confirmed by ADF-STEM and diffuse reflectance UV-vis spectroscopy. Model fuel testing revealed that PT Ag-MASN had the highest regeneration capacity after six cycles compared to non-plasma-treated (Ag-MASN) and aluminum-free materials (Ag-MSN and PT-Ag-MSN). Initial testing of the military jet fuel JP-8 also shows a high desulfurization capacity of 41 mg S.g(-1). C1 [Hauser, Jesse L.; Conley, Edward T.; Saunders, John M.; Oliver, Scott R.

We created a model and simulated range-wide population and breeding habitat dynamics for an endangered woodland warbler, the golden-cheeked warbler (Setophaga chrysoparia). Habitat-transition probabilities were estimated across the warbler's breeding range by combining National Land Cover Database imagery with multistate modeling. Using these estimates, along with recently published demographic estimates, we examined if the species can remain viable into the future given the current conditions. Lastly, we evaluated if protecting a greater amount of habitat would increase the number of warblers that can be supported in the future by systematically increasing the amount of protected habitat and comparing the estimated terminal carrying capacity at the end of 50 years of simulated habitat change. The estimated habitat-transition probabilities supported the hypothesis that habitat transitions are unidirectional, whereby habitat is more likely to diminish than regenerate. The model results indicated population viability could be achieved under current conditions, depending on dispersal. However, there is considerable uncertainty associated with the population projections due to parametric uncertainty. Model results suggested that increasing the amount of protected lands would have a substantial impact on terminal carrying capacities at the end of a 50-year simulation. Notably, this study identifies the need for collecting the data required to estimate demographic parameters in relation to changes in habitat metrics and population density in multiple regions, and highlights the importance of establishing a common definition of what constitutes protected habitat, what management goals are suitable within those protected areas, and a standard operating procedure to identify areas of priority for habitat conservation efforts. Therefore, we suggest future efforts focus on these aspects of golden-cheeked warbler conservation and ecology. (C) 2015 Elsevier B.V. All rights reserved.

TI Phosphatidylinositol 3-kinase p110 alpha mediates phosphorylation of AMP-activated protein kinase in myoblasts SO BIOCHEMICAL AND BIOPHYSICAL RESEARCH COMMUNICATIONS LA English DT Article DE Phosphatidylinositol 3-kinase (PI3K); AMP-Activated protein kinase (AMPK); p110 alpha; Akt; Myoblast ID SKELETAL-MUSCLE; EXERCISE INTENSITY; AKT ACTIVATION; INSULIN; P110-BETA; CELLS; SER(485/491); DOWNSTREAM; AGENTS; HEART AB AMP-activated protein kinase (AMPK) is a serine/threonine kinase that functions as a sensor of intracellular energy. Activation of AMPK is associated with increased phosphorylation of the a-subunit at threonine 172 (T172) and decreased phosphorylation at serine 485 in AMPK alpha 1 and serine 491 in AMPK alpha 2 (S485/491). One potential mediator of AMPK phosphorylation is phosphatidylinositol 3-kinase (PI3K); however, the mechanism and the identities of the specific PI3K isoforms that regulate AMPK activation are not known. To determine whether PI3K p110 alpha regulated AMPK activation in muscle cells, C2C12 myoblasts were subjected to pharmacological inhibition of p110 alpha, siRNA directed against p110 alpha, or overexpression of constitutively-active or dominant negative p110 alpha. Chemical inhibition, siRNA, and expression of dominant-negative p110 alpha were all associated with increased AMPK T172 phosphorylation, whereas expression of constitutively-active p110 alpha reduced T172 phosphorylation. Conversely, pharmacological inhibition of p110 alpha reduced AMPK S485/491 phosphorylation, while constitutively-active p110 alpha increased AMPK S485/491 phosphorylation. This p110 alpha-mediated increase in AMPK S485/491 phosphorylation was eliminated in the presence of the Akt inhibitor MK2206, suggesting that p110 alpha-mediated phosphorylation of AMPK alpha at S485/491 is Akt-dependent. In response to oligomycin or serum starvation, AMPK T172 phosphorylation was elevated in p11 alpha-deficient myoblasts compared to control myoblasts. Overall, our findings identify PI3K p110a as a mediator of AMPK phosphorylation in myoblasts. (C) Published by Elsevier Inc.

Unfortunately, there have only been a handful of studies on the effects of CWNA in pediatric animal models, and more research is needed to confirm this hypothesis. Using a stagewise, adaptive dose design, we estimated the 24 h median lethal dose for subcutaneous exposure to seven CWNA in both male and female Sprague-Dawley rats at six different developmental times. Perinatal (postnatal day [PND] 7, 14 and 21) and adult (PND 70) rats were more susceptible than pubertal (PND 28 and 42) rats to the lethal effects associated with exposure to tabun, sarin, soman and cyclosarin. Age-related differences in susceptibility were not observed in rats exposed to VM, Russian VX or VX. Published by Elsevier Ireland Ltd. C1 [Wright, Linnzi K.

This protocol is designed for systems where no a priori information of ligand structure (beyond sequence) or binding location is known. It provides for efficient incorporation of both ligand and target flexibility, is HPC-ready and is easily extensible for use of custom code. We apply this protocol to a set of 11 test cases drawn from benchmarking databases and from previously published studies for direct comparison with existing protocols. Strengths, weaknesses and areas of improvement are discussed. C1 [Sellers, Michael S.; Hurley, Margaret M.] US Army, Res Lab, Weap & Mat Res Directorate, Aberdeen Proving Ground, MD 21005 USA.

Brain tissue compression/tension due to blast-induced cranial deformations and shear waves due to head rotation may generate diffuse micro-damage to neuro-axonal structures and trigger a cascade of neurobiological events culminating in cognitive and neurodegenerative disorders. Although diffuse axonal injury is regarded as a signature wound of mild TBI (mTBI), blast loads may also cause synaptic injury wherein neuronal synapses are stretched and sheared. This synaptic injury may result in temporary disconnect of the neural circuitry and transient loss in neuronal communication. We hypothesize that mTBI symptoms such as loss of consciousness or dizziness, which start immediately after the insult, could be attributed to synaptic injury. Although empirical evidence is beginning to emerge; the detailed mechanisms underlying synaptic injury are still elusive. Coordinated in vitro-in vivo experiments and mathematical modeling studies can shed light into the synaptic injury mechanisms and their role in the potentiation of mTBI symptoms.

Huynh, Kim TI Manganese Oxide Nanoarchitectures as Broad-Spectrum Sorbents for Toxic Gases SO ACS APPLIED MATERIALS & INTERFACES LA English DT Article DE manganese oxide; ammonia; sulfur dioxide; hydrogen sulfide; air filtration ID SELECTIVE CATALYTIC-REDUCTION; NANOCRYSTALLINE METAL-OXIDES; SULFUR-DIOXIDE; REACTIVE ADSORPTION; SURFACE-CHEMISTRY; AQUEOUS-SOLUTIONS; HYDROGEN-SULFIDE; ETHYL SULFIDE; FT-IR; OXIDATION AB We demonstrate that sol-gel-derived manganese oxide (MnOx) nanoarchitectures exhibit broad-spectrum filtration activity for three chemically diverse toxic gases: NH3, SO2, and H2S. Manganese oxides are synthesized via the reaction of NaMnO4 and fumaric acid to form monolithic gels of disordered, mixed-talent Na-MnOx; incorporated Na+ is readily exchanged for H+ by subsequent acid rinsing to form a more crystalline H-MnOx phase. For both Na-MnOx and H-MnOx forms, controlled pore-fluid removal yields either densified, yet still mesoporous, xerogels or low-density aerogels (prepared by drying from supercritical CO2). The performance of these MnOx nanoarchitectures as filtration media is assessed using dynamic-challenge microbreakthrough protocols. We observe technologically relevant sorption capacities under both dry conditions and wet (80% relative humidity) for each of the three toxic industrial chemicals investigated. The Na-MnOx xerogels and aerogels provide optimal performance with the aerogel exhibiting maximum sorption capacities of 39, 200, and 680 mg g(-1) for NH3, SO2, and H2S, respectively. Postbreakthrough characterization using X-ray photoelectron spectroscopy (XPS) and diffuse-reflectance infrared Fourier transform spectroscopy (DRIFTS) confirms that NH3 is captured and partially protonated within the MnOx structure, while SO2 undergoes oxidation by the redox-active oxide to form adsorbed sulfate at the MnOx surface. Hydrogen sulfide is also oxidized to form a combination of sulfate and sulfur/polysulfide products, concomitant with a decrease in the average Mn oxidation state from 3.43 to 2.94 and generation of a MnOOH phase.

TI Safety and immunogenicity of a mutagenized, live attenuated Rift Valley fever vaccine, MP-12, in a Phase 1 dose escalation and route comparison study in humans SO VACCINE LA English DT Article DE MP-12; Rift Valley fever; Vaccine; Clinical trial ID VIRUS-VACCINE; AEROSOL CHALLENGE; RHESUS-MONKEYS; PREGNANT SHEEP; SAUDI-ARABIA; NSM GENES; PATHOGENICITY; PROTECTION; INFECTION; EFFICACY AB Rift Valley fever (RVF) poses a risk as a potential agent in bioterrorism or agroterrorism. A live attenuated RVF vaccine (RVF MP-12) has been shown to be safe and protective in animals and showed promise in two initial clinical trials. In the present study, healthy adult human volunteers (N=56) received a single injection of (a) RVF MP-12, administered subcutaneously (SQ) at a concentration of 10(4.7) plaque-forming units (pfu) (SQ Group); (b) RVF MP-12, administered intramuscularly (IM) at 10(3.4) pfu (IM Group 1); (c) RVF MP-12, administered IM at 10(4.4) pfu (IM Group 2); or (d) saline (Placebo Group). The vaccine was well tolerated by volunteers in all dose and route groups. Infrequent and minor adverse events were seen among recipients of both placebo and RVF MP-12. One subject had viremia detectable by direct plaque assay, and six subjects from IM Group 2 had transient low-titer viremia detectable only by nucleic acid amplification. Of the 43 vaccine recipients, 40 (93%) achieved neutralizing antibodies (measured as an 80% plaque reduction neutralization titer [PRNT80]) as well as RVF-specific IgM and IgG. The highest peak geometric mean PRNT80 titers were observed in IM Group 2. Of 34 RVF MP-12 recipients available for testing 1 year following inoculation, 28 (82%) remained seropositive (PRNT80 >= 1:20); this included 20 of 23 vaccinees (87%) from IM Group 2. The live attenuated RVF MP-12 vaccine was safe and immunogenic at the doses and routes studied. Given the need for an effective vaccine against RVF virus, further evaluation in humans is warranted.

The fractional change in resistance of the sensor upon exposure to these compounds exhibits a similar response magnitude among compounds, whereas large variation is observed within repetitions for each compound, causing a response overlap. Therefore, traditional features depending on maximum response change will cause confusion during further discrimination and classification analysis. More robust features that are less sensitive to concentration, sampling, and drift variability would provide higher quality information. In this work, we have explored the advantage of using transient-based exponential fitting coefficients to enhance the discrimination of similar compounds. The advantages of such feature analysis to discriminate each compound is evaluated using principle component analysis (PCA). In addition, machine learning-based classification algorithms were used to compare the prediction accuracies when using fitting coefficients as features. The additional features greatly enhanced the discrimination between compounds while performing PCA and also improved the prediction accuracy by 34% when using linear discrimination analysis.

The feasibility of using peripheral blood counterparts of lymph node Tfh cells to assess the immune response and the influence of viral and vaccine antigens on their helper functions remain obscure. We assessed circulating HIV-specific IL-21(+) CD4(+) T cells and showed transcriptional and phenotypic similarities to lymphoid Tfh cells, and hence representing peripheral Tfh (pTfh) cells. pTfh cells were functionally active and B cell helper quality differed depending on antigen specificity. Furthermore, we found higher frequency of pTfh cells in peripheral blood mononuclear cell specimens from the ALVAC+AIDSVAX (RV144) HIV vaccine trial associated with protective antibody responses compared to the non-protective DNA+Ad5 vaccine trial. Together, we identify IL-21(+) CD4(+) T cells as pTfh cells, implicating them as key populations in the generation of vaccine-evoked antibody responses.

Kott, Alexander Mangoubi, Rami Linkov, Igor TI Operational resilience: concepts, design and analysis SO SCIENTIFIC REPORTS LA English DT Article ID INFRASTRUCTURE SYSTEMS; DYNAMICAL NETWORKS; COMPLEX NETWORKS; FRAMEWORK; FRAGILITY; FAILURES AB Building resilience into today's complex infrastructures is critical to the daily functioning of society and its ability to withstand and recover from natural disasters, epidemics, and cyber-threats. This study proposes quantitative measures that capture and implement the definition of engineering resilience advanced by the National Academy of Sciences. The approach is applicable across physical, information, and social domains. It evaluates the critical functionality, defined as a performance function of time set by the stakeholders. Critical functionality is a source of valuable information, such as the integrated system resilience over a time interval, and its robustness. The paper demonstrates the formulation on two classes of models: 1) multi-level directed acyclic graphs, and 2) interdependent coupled networks. For both models synthetic case studies are used to explore trends. For the first class, the approach is also applied to the Linux operating system. Results indicate that desired resilience and robustness levels are achievable by trading off different design parameters, such as redundancy, node recovery time, and backup supply available. The nonlinear relationship between network parameters and resilience levels confirms the utility of the proposed approach, which is of benefit to analysts and designers of complex systems and networks.

TI Repeated exposure to neurotoxic levels of chlorpyrifos alters hippocampal expression of neurotrophins and neuropeptides SO TOXICOLOGY LA English DT Article DE Chlorpyrifos; Cholinesterase inhibition; Gene expression; Microarray; miRNA Organophosphorus pesticide ID LONG-TERM EXPOSURE; NEUROBEHAVIORAL PERFORMANCE; ORGANOPHOSPHATE PESTICIDES; UP-REGULATION; RNA-SEQ; WORKERS; MEMORY; NEURONS; RATS; CARBAMATE AB Chlorpyrifos (CPF), an organophosphorus pesticide (OP), is one of the most widely used pesticides in the world. Subchronic exposures to CPF that do not cause cholinergic crisis are associated with problems in cognitive function (i.e., learning and memory deficits), but the biological mechanism(s) underlying this association remain speculative. To identify potential mechanisms of subchronic CPF neurotoxicity, adult male Long Evans (LE) rats were administered CPF at 3 or 10 mg/kg/d (s.c.) for 21 days. We quantified mRNA and non-coding RNA (ncRNA) expression profiles by RNA-seq, microarray analysis and small ncRNA sequencing technology in the CA1 region of the hippocampus. Hippocampal slice immunohistochemistry was used to determine CPF-induced changes in protein expression and localization patterns. Neither dose of CPF caused overt clinical signs of cholinergic toxicity, although after 21 days of exposure, cholinesterase activity was decreased to 58% or 13% of control levels in the hippocampus of rats in the 3 or 10 mg/kg/d groups, respectively. Differential gene expression in the CA1 region of the hippocampus was observed only in the 10 mg/kg/d dose group relative to controls. Of the 1382 differentially expressed genes identified by RNA-seq and microarray analysis, 67 were common to both approaches. Differential expression of six of these genes (Bdnf,Cort, Crhbp, Nptx2, Npy and Pnoc) was verified in an independent CPF exposure study; immunohistochemistry demonstrated that CRHBP and NPY were elevated in the CAl region of the hippocampus at 10 mg/kg/d CPF. Gene ontology enrichment analysis suggested association of these genes with receptor-mediated cell survival signaling pathways. miR132/212 was also elevated in the CAl hippocampal region, which may play a role in the disruption of neurotrophin-mediated cognitive processes after CPF administration. These findings identify potential mediators of CPF-induced neurobehavioral deficits following subchronic exposure to CPF at a level that inhibits hippocampal cholinesterase to less than 20% of control. An equally significant finding is that subchronic exposure to CPF at a level that produces more moderate inhibition of hippocampal cholinesterase (approximately 50% of control) does not produce a discernable change in gene expression.

TI The Transcription Factor ARID3a Is Important for In Vitro Differentiation of Human Hematopoietic Progenitors SO JOURNAL OF IMMUNOLOGY LA English DT Article ID SYSTEMIC-LUPUS-ERYTHEMATOSUS; B-CELL DIFFERENTIATION; DNA-BINDING PROTEINS; STEM-CELL; FACTOR BRIGHT; MYELOID LINEAGE; RINGER GENE; V-REGION; FAMILY; EXPRESSION AB We recently reported that the transcription factor ARID3a is expressed in a subset of human hematopoietic progenitor stem cells in both healthy individuals and in patients with systemic lupus erythematosus. Numbers of ARID3a(+) lupus hematopoietic stem progenitor cells were associated with increased production of autoreactive Abs when those cells were introduced into humanized mouse models. Although ARID3a/Bright knockout mice died in utero, they exhibited decreased numbers of hematopoietic stem cells and erythrocytes, indicating that ARID3a is functionally important for hematopoiesis in mice. To explore the requirement for ARID3a for normal human hematopoiesis, hematopoietic stem cell progenitors from human cord blood were subjected to both inhibition and overexpression of ARID3a in vitro. Inhibition of ARID3a resulted in decreased B lineage cell production accompanied by increases in cells with myeloid lineage markers. Overexpression of ARID3a inhibited both myeloid and erythroid differentiation. Additionally, inhibition of ARID3a in hematopoietic stem cells resulted in altered expression of transcription factors associated with hematopoietic lineage decisions. These results suggest that appropriate regulation of ARID3a is critical for normal development of both myeloid and B lineage pathways.

TI Ability of Serum Glial Fibrillary Acidic Protein, Ubiquitin C-Terminal Hydrolase-L1, and S100B To Differentiate Normal and Abnormal Head Computed Tomography Findings in Patients with Suspected Mild or Moderate Traumatic Brain Injury SO JOURNAL OF NEUROTRAUMA LA English DT Article ID NEW-ORLEANS CRITERIA; INTRACRANIAL LESIONS; NEUROSURGICAL INTERVENTION; RULE; BIOMARKERS; MANAGEMENT; S100-BETA; DIAGNOSIS; ACCURACY; BLOOD AB Head computed tomography (CT) imaging is still a commonly obtained diagnostic test for patients with minor head injury despite availability of clinical decision rules to guide imaging use and recommendations to reduce radiation exposure resulting from unnecessary imaging. This prospective multicenter observational study of 251 patients with suspected mild to moderate traumatic brain injury (TBI) evaluated three serum biomarkers' (glial fibrillary acidic protein [GFAP], ubiquitin C-terminal hydrolase-L1 [UCH-L1] and S100B measured within 6h of injury) ability to differentiate CT negative and CT positive findings. Of the 251 patients, 60.2% were male and 225 (89.6%) had a presenting Glasgow Coma Scale score of 15. A positive head CT (intracranial injury) was found in 36 (14.3%). UCH-L1 was 100% sensitive and 39% specific at a cutoff value >40pg/mL. To retain 100% sensitivity, GFAP was 0% specific (cutoff value 0pg/mL) and S100B had a specificity of only 2% (cutoff value 30pg/mL). All three biomarkers had similar values for areas under the receiver operator characteristic curve: 0.79 (95% confidence interval; 0.70-0.88) for GFAP, 0.80 (0.71-0.89) for UCH-L1, and 0.75 (0.65-0.85) for S100B. Neither GFAP nor UCH-L1 curve values differed significantly from S100B (p=0.21 and p=0.77, respectively). In our patient cohort, UCH-L1 outperformed GFAP and S100B when the goal was to reduce CT use without sacrificing sensitivity. UCH-L1 values <40pg/mL could potentially have aided in eliminating 83 of the 215 negative CT scans. These results require replication in other studies before the test is used in actual clinical practice.

The production of PDLs leads to void growth and particle decoherence. In this work we use dislocation dynamics simulations to characterize two mechanisms for PDL formation. The first mechanism corresponds to a classical model of PDL generation from dislocation nucleation. The second mechanism considers PDL generation through cross-slip of a screw dislocation intersecting the particle. We systematically study the effect of the crystal lattice and defect type on PDL generation for both mechanisms as a function of pressure. The simulations show image stresses produced by the dislocation's interaction with the free surface of a void suppresses PDL generation. The highest PDL generation rates are found for a dislocation nucleated from a void in a body-centered cubic lattice. Our simulations also show helical coiling of screw dislocations produces a continuous emission of PDLs without the need for dislocation nucleation at pressures as low as 1.0 GPa.

Adsorption of such gas streams by activated carbon fiber cloths (ACFCs) and subsequent controlled desorption can provide gas streams of well-defined concentration that can then be more efficiently treated by biofiltration than streams exhibiting large variability in concentration. In this study, we passed VOC-containing gas through an ACFC vessel for adsorption and then desorption in a concentration-controlled manner via electrothermal heating. Set-point concentrations (40-900 ppm(v)) and superficial gas velocity (6.3-9.9 m/s) were controlled by a data acquisition and control system. The results of the average VOC desorption, desorption factor and VOC in-and-out ratio were calculated and compared for various gas set-point concentrations and superficial gas velocities. Our results reveal that desorption is strongly dependent on the set-point concentration and that the VOC desorption rate can be successfully equalized and controlled via an electrothermal adsorption system.

TI Detection of palytoxin-like compounds by a flow cytometry-based immunoassay supported by functional and analytical methods SO ANALYTICA CHIMICA ACTA LA English DT Article DE Palytoxin; Palytoxin-like molecules; Microsphere-based array; Flow-cytometry system; Screening method ID SHELLFISH POISONING TOXINS; OSTREOPSIS-CF. SIAMENSIS; OF-THE-ART; MASS-SPECTROMETRY; 1ST EVIDENCE; OVATOXIN-A; ANALOGS; SYSTEM; ASSAY; INHIBITION AB Palytoxin (PLTX) is a complex marine toxin produced by zoanthids (i.e. Palythoa), dinoflagellates (Ostreopsis) and cyanobacteria (Trichodesmium). PLTX outbreaks are usually associated with Indo-Pacific waters, however their recent repeated occurrence in Mediterranean-European Atlantic coasts demonstrate their current worldwide distribution. Human sickness and fatalities have been associated with toxic algal blooms and ingestion of seafood contaminated with PLTX-like molecules. These toxins represent a serious threat to human health. There is an immediate need to develop easy-to-use, rapid detection methods due to the lack of validated protocols for their detection and quantification. We have developed an immuno-detection method for PLTX-like molecules based on the use of microspheres coupled to flow-cytometry detection (Luminex 200 (TM)). The assay consisted of the competition between free PLTX-like compounds in solution and PLTX immobilized on the surface of microspheres for binding to a specific monoclonal anti-PLTX antibody. This method displays an IC50 of 1.83 +/- 0.21 nM and a dynamic range of 0.47-6.54 nM for PLTX. An easy-to-perform extraction protocol, based on a mixture of methanol and acetate buffer, was applied to spiked mussel samples providing a recovery rate of 104 +/- 8% and a range of detection from 374 +/- 81 to 4430 +/- 150 mu g kg(-1) when assayed with this method. Extracts of Ostreopsis cf. siamensis and Palythoa tuberculosa were tested and yielded positive results for PLTX-like molecules. However, the data obtained for the coral sample suggested that this antibody did not detect 42-OH-PLTX efficiently. The same samples were further analyzed using a neuroblastoma cytotoxicity assay and UPLC-IT-TOF spectrometry, which also pointed to the presence of PLTX-like compounds. Therefore, this single detection method for PLTX provides a semi-quantitative tool useful for the screening of PLTX-like molecules in different matrixes. (C) 2015 Elsevier B.V. All rights reserved.

Specifically, oxalic acid and sodium hydroxide (NaOH) were used as additives to promote the conversion of titanium tetraisopropoxide (TTIP) into a one-dimensional TiO2 morphology. All resultant products were characterized by X-ray powder diffraction and scanning electron microscopy. Influential factors on the growth mechanisms of TiO2 nanorods are discussed. This approach contrasts the typical approach of using spherical TiO2 as a starting material in the fabrication of one-dimensional TiO2 structures, and instead allows for the direct synthesis of TiO2 nanorods from TTIP precursors.

The compounds exhibited pronounced in vitro and in vivo activity against Plasmodium berghei in the Thompson test. Tethering a fluorine atom to the aminoquinoline C(3) position afforded fluoroaminoquinolines that act as intrahepatocytic parasite inhibitors, with compound 25 having an IC50 = 0.31 mu M and reducing the liver load in mice by up to 92% at 80 mg/kg dose. Screening our peroxides as inhibitors of liver stage infection revealed that the tetraoxane pharmacophore itself is also an excellent liver stage P. berghei inhibitor (78: IC50 = 0.33 mu M). Up to 91% reduction of the parasite liver load in mice was achieved at 100 mg/kg. Examination of tetraoxane 78 against the transgenic 3D7 strain expressing luciferase under a gametocyte-specific promoter revealed its activity against stage IV-V Plasmodium falciparum gametocytes (IC50 = 1.16 +/- 0.37 mu M). To the best of our knowledge, compounds 25 and 78 are the first examples of either an 4-aminoquinoline or a tetraoxane liver stage inhibitors.

In this work, we studied nonlinear dielectric properties of a biaxially oriented poly(vinylidene fluoride) (BOPVDF) film under both low and high electric fields. For fundamental nonlinear dielectric constants at low fields (<30 MV/m), Novocontrol high-voltage broadband dielectric spectroscopy (HVBDS) was accurate enough to measure up to the third harmonics. It was observed that the low-field dielectric nonlinearity for the BOPVDF disappeared above 10 Hz at room temperature, suggesting that the low-field dielectric nonlinearity originated from ionic migration of impurity ions rather than dipolar relaxation of the amorphous segments. Above the coercive field (E-C approximate to 70 MV/m), bipolar electric displacement-electric field (D-E) loop tests were used to extract the nonlinear behavior for pure PVDF crystals, which had a clear origin of ferroelectric switching of polar crystalline dipoles and domains and nonpolar-to-polar (alpha -> delta -> beta) phase transformations. By using HVBDS, it was observed that the ferroelectric switching of polar crystalline dipoles and domains in BOPVDF above the E-C always took place between 20 and 500 Hz regardless of a broad range of temperature from -30 to 100 degrees C. This behavior was drastically different from that of the amorphous PVDF dipoles, which had a strong dependence on frequency over orders of magnitude.

Corresponding unconfined pillars were also fabricated. The samples were coated with 1.5, 3, or 6 nm of Al2O3 ALD. These samples were tested in electrolytes of 3:7 by weight ethylene carbonate:ethyl methyl carbonate (EC:EMC) with 1.2 M LiPF6 salt with and without 2% fluoroethylene carbonate (FEC) and in a pure FEC electrolyte with 10 wt % LiPF6. The samples were imaged with an atomic force microscope during electrochemical cycling to evaluate morphology evolution and solid electrolyte interphase (SEI) formation. The partially confined alpha-Si structures had superior cycle efficiency relative to the unconfined alpha-Si pillars. Additionally, samples with 3 nm of ALD achieved higher charge capacity and enhanced cycle life compared to samples without ALD, demonstrated thinner SEI formation, and after 10 cycles at a 1 C rate remained mostly intact and had actually decreased in diameter. Finally, the samples with 3 nm of ALD had better capacity retention in the baseline 3:7 EC:EMC than in either of the FEC containing electrolytes.

TI Bispecific Antibody Affords Complete Post-Exposure Protection of Mice from Both Ebola (Zaire) and Sudan Viruses SO SCIENTIFIC REPORTS LA English DT Article ID ENVELOPE GLYCOPROTEIN; NONHUMAN-PRIMATES; MONOCLONAL-ANTIBODIES; SYNTHETIC ANTIBODIES; CRYSTAL-STRUCTURE; INFECTION; PROPHYLAXIS; DISEASE; MODEL; GP2 AB Filoviruses (Ebola and Marburg) cause severe hemorrhagic fever. There are five species of ebolavirus; among these, the Ebola (Zaire) and Sudan viruses (EBOV and SUDV, respectively) are highly pathogenic and have both caused recurring, large outbreaks. However, the EBOV and SUDV glycoprotein (GP) sequences are 45% divergent and thus antigenically distinct. Few antibodies with cross-neutralizing properties have been described to date. We used antibody engineering to develop novel bispecific antibodies (Bis-mAbs) that are cross-reactive toward base epitopes on GP from EBOV and SUDV. These Bis-mAbs exhibit potent neutralization against EBOV and SUDV GP pseudotyped viruses as well as authentic pathogens, and confer a high degree (in one case 100%) post-exposure protection of mice from both viruses. Our studies show that a single agent that targets the GP base epitopes is sufficient for protection in mice; such agents could be included in panfilovirus therapeutic antibody cocktails.

TI Predicting Fecundity of Fathead Minnows (Pimephales promelas) Exposed to Endocrine-Disrupting Chemicals Using a MATLAB (R)-Based Model of Oocyte Growth Dynamics SO PLOS ONE LA English DT Article ID TERM REPRODUCTION ASSAY; PITUITARY-GONADAL AXIS; COMPUTATIONAL MODEL; FISH; INHIBITOR; 17-BETA-TRENBOLONE; STEROIDOGENESIS; ECOTOXICOLOGY; BIOSYNTHESIS; KETOCONAZOLE AB Fish spawning is often used as an integrated measure of reproductive toxicity, and an indicator of aquatic ecosystem health in the context of forecasting potential population-level effects considered important for ecological risk assessment. Consequently, there is a need for flexible, widely-applicable, biologically-based models that can predict changes in fecundity in response to chemical exposures, based on readily measured biochemical endpoints, such as plasma vitellogenin (VTG) concentrations, as input parameters. Herein we describe a MATLAB1 version of an oocyte growth dynamics model for fathead minnows (Pimephales promelas) with a graphical user interface based upon a previously published model developed with MCSim software and evaluated with data from fathead minnows exposed to an androgenic chemical, 17 beta-trenbolone. We extended the evaluation of our new model to include six chemicals that inhibit enzymes involved in steroid biosynthesis: fadrozole, ketoconazole, propiconazole, prochloraz, fenarimol, and trilostane. In addition, for unexposed fathead minnows from group spawning design studies, and those exposed to the six chemicals, we evaluated whether the model is capable of predicting the average number of eggs per spawn and the average number of spawns per female, which was not evaluated previously. The new model is significantly improved in terms of ease of use, platform independence, and utility for providing output in a format that can be used as input into a population dynamics model. Model-predicted minimum and maximum cumulative fecundity over time encompassed the observed data for fadrozole and most propiconazole, prochloraz, fenarimol and trilostane treatments, but did not consistently replicate results fromketoconazole treatments. For average fecundity (eggs.female(-1).day(-1)), eggs per spawn, and the number of spawns per female, the range of model-predicted values generally encompassed the experimentally observed values. Overall, we found that the model predicts reproduction metrics robustly and its predictions capture the variability in the experimentally observed data.

Methods: In order to better assess the potential use of MSP1 serology in malaria chemoprophylaxis trials in endemic areas, an analysis for the prevalence of antibodies to both Plasmodium falciparum and Plasmodium vivax MSP1(42) in healthy Cambodian adults was conducted at two sites as part of an active, observational cohort evaluating the efficacy of dihydroartemisinin-piperaquine (DP) for uncomplicated malaria (ClinicalTrials.gov identifier NCT01280162). Results: Rates of baseline sero-positivity were high (59 and 73 % for PfMSP1(42) and PvMSP1(42), respectively), and titers higher in those who lived in a higher transmission area, although there was little correlation in titers between the two species. Those volunteers who subsequently went on to develop malaria had higher baseline MSP1(42) titers than those who did not for both species. Titers to both antigens remained largely stable over the course of the 4-6 month study, except in those infected with P. falciparum who had multiple recurrences. Conclusion: These findings illuminate the difficulties in using MSP1(42) serology as either a screening criterion and/or biomarker of exposure in chemoprophylaxis studies. Further work remains to identify useful markers of malarial infection and/or immunity.

A coordination preference for EC over DMC to a Li+ was found at low salt concentrations, while a slightly higher preference for DMC over EC was found at high salt concentrations. Analysis of the relative binding energies of the (EC)(n)(DMC)(m) Li+ and (EC)(n)(DMC)(m)-LiPF6 solvates in the gas-phase and for an implicit solvent (as a function of the solvent dielectric constant) indicated that the DMC-containing Li+ solvates were stabilized relative to (EC4)-Li+ and (EC)(3)-LiPF6 by immersing them in the implicit solvent. Such stabilization was more pronounced in the implicit solvents with a high dielectric constant. Results from previous Raman and IR experiments were reanalyzed and reconciled by correcting them for changes of the Raman activities, IR intensities and band shifts for the solvents which occur upon Li+ coordination. After these correction factors were applied to the results of BOMD simulations, the composition of the Li+ solvation shell from the BOMD simulations was found to agree well with the solvation numbers extracted from Raman experiments. Finally, the mechanism of the Li+ diffusion in the dilute (EC:DMC)LiPF6 mixed solvent electrolyte was studied using the BOMD simulations.

The many-body polarizable APPLE&P force field has been utilized. The influence of anion polarization on the structure of the first coordination shell of Li+ was examined. In particular, the reduction of the oxygen of the TFSI anion (O-TFSI) polarizability from 1.36 angstrom(3) to 1.00 angstrom(3) resulted in an increased fraction of the TFSI anion bidentate coordination to the Li+. While the overall dynamics in [pyr(13)][TFSI]-based ILEs was slower than in [emim][TFSI]-based ILEs, the exchange of TFSI anions in and out of the first coordination shell of Li+ was found to be faster in pyr(13)-based systems. The Li+ ion transference number is higher for these systems as well. These trends can be related to the difference in interaction of TFSI with the IL cation which is stronger for pyr(13) than for emim.

TI Importance of Ion Packing on the Dynamics of Ionic Liquids during Micropore Charging SO JOURNAL OF PHYSICAL CHEMISTRY LETTERS LA English DT Article ID SUBNANOMETER PORES; FILLED NANOPORES; SLIT NANOPORE; CAPACITANCE; CARBON; SUPERCAPACITORS; SIMULATIONS; SIZE; ELECTRODES; STORAGE AB Molecular simulations of the diffusion of EMIM+ and TESI- ions in slit-shaped micropores under conditions similar to those during charging show that in pores that accommodate only a single layer of ions, ions diffuse increasingly faster as the pore becomes charged (with diffusion coefficients even reaching similar to 5 x 10(-9) m(2)/s), unless the pore becomes very highly charged. In pores wide enough to fit more than one layer of ions, ion diffusion is slower than in the bulk and changes modestly as the pore becomes charged. Analysis of these results revealed that the fast (or slow) diffusion of ions inside a micropore during charging is correlated most strongly with the dense (or loose) ion packing inside the pore. The molecular details of the ions and the precise width of the pores modify these trends weakly, except when the pore is so narrow that the ion conformation relaxation is strongly constrained by the pore walls.

Linkov, Igor TI Emerging Technologies for Environmental Remediation: Integrating Data and Judgment SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID MULTICRITERIA DECISION-ANALYSIS; SYNTHETIC-BIOLOGY; RISK-ASSESSMENT; NANOMATERIALS; NZVI AB Emerging technologies present significant challenges to researchers, decision-makers, industry professionals, and other stakeholder groups due to the lack of quantitative risk, benefit, and cost data associated with their use. Multi-criteria decision analysis (MCDA) can support early decisions for emerging technologies when data is too sparse or uncertain for traditional risk assessment. It does this by integrating expert judgment with available quantitative and qualitative inputs across multiple criteria to provide relative technology scores. Here, an MCDA framework provides preliminary insights on the suitability of emerging technologies for environmental remediation by comparing nanotechnology and synthetic biology to conventional remediation methods. Subject matter experts provided judgments regarding the importance of criteria used in the evaluations and scored the technologies with respect to those criteria. The results indicate that synthetic biology may be preferred over nanotechnology and conventional methods for high expected benefits and low deployment costs but that conventional technology may be preferred over emerging technologies for reduced risks and development costs. In the absence of field data regarding the risks, benefits, and costs of emerging technologies, structuring evidence-based expert judgment through a weighted hierarchy of topical questions may be helpful to inform preliminary risk governance and guide emerging technology development and policy.

TI Sex and Urbanicity Contribute to Variation in Lymphocyte Distribution across Ugandan Populations SO PLOS ONE LA English DT Article ID REFERENCE INTERVALS; IMMUNE-RESPONSES; HEALTHY UGANDANS; REFERENCE VALUES; REFERENCE RANGES; VACCINE; TRIALS; ADULTS; EOSINOPHILS; INFECTION AB Management of patient care and interpretation of research data require evaluation of laboratory results in the context of reference data from populations with known health status to adequately diagnose disease or make a physiological assessment. Few studies have addressed the diversity of lymphocyte subsets in rural and urban Ugandan populations. Here, 663 healthy blood bank donors from semi-urban centers of Kampala consented to participate in a study to define lymphocyte reference ranges. Whole blood immunophenotyping was performed to determine the frequency and absolute counts of T, B, and NK cells using clinical flow cytometry. Results from blood bank donors were compared to a rural cohort from the district of Kayunga and more urban clinical trial participants from the capital city, Kampala. Relationships between hematological and lymphocyte parameters were also explored. In the semi-urban blood donors, females were significantly different from males in all parameters except the frequency of CD8 T and B cells. Females had higher absolute counts of CD4 T, CD8 T and B cells, whereas males had higher NK cell counts. NK cell frequency and counts were significantly higher in semi-urban blood donors, regardless of sex, compared to more urban study participants. CD8 T cell frequency and counts were significantly higher in the blood donors compared to the rural participants, irrespective of sex. Interestingly, basophil counts were positively associated with overall T cell counts. These findings suggest that both sex and level of cohort urbanicity may influence lymphocyte subset distributions in Ugandans.

Multiple studies have tried to determine if cinnamon is an effective treatment for diabetes. Cinnamon extract is an insulin sensitizer, protects mesangial cells, decreases inflammatory markers, and lowers glucose, lipids, and blood pressure in patients with type 2 diabetes, so we developed a protocol to study whether ingestion of water-soluble cinnamon extract prevents progression from pre-diabetes to diabetes. Methods/design: This is a randomized, double-blind, placebo-controlled trial comparing cinnamon extract versus placebo in subjects with pre-diabetes who have committed to participate in a lifestyle change program. The trial will be conducted at five sites and will include 428 subjects who take cinnamon extract or placebo for 1 year. Follow-up for these subjects will be for a total of 2 years (nine study visits). The primary outcomes to be assessed are 1) conversion of patients from pre-diabetes to diabetes and 2) impact of water-soluble cinnamon extract on hepatic transaminases, renal function, and QT interval on electrocardiogram. Secondary outcomes include changes in HbA1c, lipids, waist circumference, weight, blood pressure, and fasting plasma glucose. The trial protocol has been approved by the Institutional Review Board of the US Air Force 59th Medical Wing, Wilford Hall Ambulatory Surgical Center (Protocol FWH20110035H). Investigator-sponsored Investigational New Drug status (114078) was granted by the US Food and Drug Administration. Discussion: This study will provide high-quality evidence of the efficacy of water-soluble cinnamon extract in conjunction with lifestyle intervention for preventing patients with pre-diabetes from converting to diabetes. Additionally, it will provide important safety information about water-soluble cinnamon extract. C1 [Crawford, Paul] Nellis Family Med Residency, Las Vegas, NV 89191 USA.

Quantitative mobility spectrum analysis (QMSA) was employed to study the mobility and to isolate and identify surface carriers following SAM treatments on planar samples. QMSA data collected following the deposition of the SAMs on InAs/GaSb material correlates well with dark current measurements, demonstrating the usefulness of QMSA as a tool for evaluating surface conductivity and predicting device performance. All samples displayed a reduction in surface conductivity and dark current density following thiol treatment. Dark current densities were reduced to 1.1 x 10(-5), 1.3 x 10(-5), 1.6 x 10(-5), and 5 x 10(-6) A/cm(2) for hexanethiol, dodecanethiol, octadecanethiol, and cysteamine, respectively, from 5.7 x 10(-4) A cm(2) for unpassivated devices.

Despite its disease burden, a safe and effective RSV vaccine has remained elusive. In recent years, improved understanding of RSV biology and innovations in immunogen design has resulted in the advancement of multiple vaccine candidates into the clinical development pipeline. Given the growing number of vaccines in clinical trials, the rapid pace at which they are being tested, and the likelihood that an RSV vaccine will reach the commercial market in the next 5-10 years, consensus and guidance on clinical development pathways and licensure routes are needed now, before large-scale efficacy trials commence. In pursuit of this aim, the World Health Organization convened the first RSV vaccine consultation in 15 years on the 23rd and 24th of March, 2015 in Geneva, Switzerland. The meeting's primary objective was to provide guidance on clinical endpoints and development pathways for vaccine trials with a focus on considerations of low- and middle-income countries. Meeting participants reached consensus on candidate case definitions for RSV disease, considerations for clinical efficacy endpoints, and the clinical development pathway for active and passive immunization trials in maternal and pediatric populations. The strategic focus of this meeting was on the development of high quality, safe and efficacious RSV preventive interventions for global use and included; (1) maternal/passive immunization to prevent RSV disease in infants less than 6 months; (2) pediatric immunization to prevent RSV disease in infants and young children once protection afforded by maternal immunization wanes.

The methodology employs geospatial analyses and a geostatistical approach, and data from ground-based sensors and satellite-based estimates of solar insolation (i.e. total amount of solar radiation energy received on a given surface area during a given time) considering the spatial variability of the data. The applicability of the methodology is demonstrated by using Geostationary Operational Environmental Satellite (GOES)-estimated and 29 ground sensor-based observed solar insolation data in the South Florida region of the USA. Results indicate that the optimal design of network depends on the spatial variability of insolation, analysis block size defined based on region-specific radiation characteristics, and the standard error used as a metric of network estimation accuracy.

TI A survey of anthropometry and physical accommodation in ergonomics curricula SO ERGONOMICS LA English DT Article DE Ergonomics tools and methods; anthropometry; ergonomics education; physical ergonomics ID DESIGN AB The size and shape of users are an important consideration for many products and environments. Designers and engineers in many disciplines must often accommodate these attributes to meet objectives such as fit and safety. When practitioners have academic training in addressing these issues, it is typically through courses in Human Factors/Ergonomics (HF/E). This paper investigates education related to physical accommodation and offers suggestions for improvement. A survey was conducted wherein 21 instructors at 18 universities in the United States provided syllabi for 29 courses, which were analysed to determine topics related to anthropometry and resources used for the courses. The results show that within the US, anthropometry is covered in the majority of courses discussing physical ergonomics, but important related concepts were often omitted (e.g. digital human modelling, multivariate accommodation and variability across global populations). Curricula could be improved by incorporating more accurate anthropometry, multivariate problems and interactive online tools. Practitioner Summary: This paper describes a study investigating collegiate ergonomics courses within the US in the area of physical accommodation. Course schedules and texts were studied for their treatment of several topics related to accommodating the spatial requirements (anthropometry) of users. Recommendations are made for improving course curricula. C1 [Parkinson, Matthew B.] Penn State Univ, Engn Design Mech Engn & Ind Engn, University Pk, PA 16802 USA.

Exploring the Connection Between Women's Rights and Terrorism SO JOURNAL OF HUMAN RIGHTS LA English DT Article ID TRANSNATIONAL TERRORISM; GENDER INEQUALITY; INTERNAL CONFLICT; FEMALE TERRORISM; CHILD WITNESSES; VETO PLAYERS; CIVIL-WAR; VIOLENCE; DEMOCRACY; EQUALITY AB Previous large-N studies have found that the advancement of women's rights leads to a decline in conflict, but no large-N research has explored the possibility of a similar relationship between women's rights and terrorism. Nevertheless, policymakers have long argued that the advancement of women's rights forms a key component of counterterrorism policy. Simply put, we lay out a rationale for the argument that increased women's rights reduce the likelihood of terrorism. We test this hypothesis using CIRI's women's rights data combined with two datasets accounting for domestic terrorism and the production of transnational terrorism. While the results show that women's rights overall are not a panacea for both types of terrorism, the provision of women's rights is shown to have a negative relationship with domestic terrorism. States and international institutions should take the differing effects of women's rights across different types of terrorism into account when designing counterterrorism policies.

In this study, male Sprague-Dawley rats (300-350g) were exposed to 600mgxmin/m(3) of soman or vehicle in a customized head-out inhalation system for 7min. Convulsant animals were observed for clinical signs and various regions of the brain (dorsolateral thalamus, basolateral amygdala, piriform cortex, and lateral cortex) were collected for pathological observations 24h post-exposure. Signs of CWNA-induced cholinergic crises including salivation, lacrimation, increased urination and defecation, and tremors were observed in all soman-exposed animals. Soman-exposed animals at 24h post-exposure lost 11% of their body weight in comparison to 2% in vehicle-exposed animals. Whole blood acetylcholinesterase (AChE) activity was significantly inhibited in all soman-exposed groups in comparison to controls. Brain injury was confirmed by the neurological assessment of hematoxylin-eosin (H&E) staining and microscopy in the piriform cortex, dorsolateral thalamus, basolateral amygdala, and lateral cortex. Severe damage including prominent lesions, edematous, congested, and/or hemorrhagic tissues was observed in the piriform cortex, dorsolateral thalamus, and lateral cortex in soman-exposed animals 24h post-exposure, while only minimal damage was observed in the basolateral amygdala. These results indicate that inhalation exposure to soman vapor causes neurological toxicity and brain injury in untreated unanesthetized rats. This study demonstrates the ability of the described soman vapor inhalation exposure model to cause neurological damage 24h post-exposure in rats.

Analyze US combat casualty data from the Department of Defense Trauma Registry (DoDTR) with a primary focus on prehospital pain assessment, analgesic administration and documentation. Retrospective cohort study of battlefield prehospital and hospital casualty data were abstracted by DoDTR from available records from 1 September 2007 through 30 June 2011. Data included demographics; injury mechanism; prehospital and initial combat hospital pain assessment documented by standard 0-to-10 numeric rating scale; analgesics administered; and survival outcome. Records were available for 8,913 casualties (median ISS of 5 [IQR 2 to 10]; 98.7% survived). Prehospital analgesic administration was documented for 1,313 cases (15%). Prehospital pain assessment was recorded for 581 cases (7%; median pain score 6 [IQR 3 to 8]), hospital pain assessment was recorded for 5,007 cases (56%; median pain score5 [CI95% 3 to 8]), and 409 cases (5%) had both prehospital and hospital pain assessments that could be paired. In this paired group, 49.1% (201/409) had alleviation of pain evidenced by a decrease in pain score (median 4,, IQR 2 to 5); 23.5% (96/409) had worsening of pain evidenced by an increase in pain score (median 3, CI95 2.8 to 3.7, IQR 1 to 5); 27.4% (112/409) had no change; and the overall difference was an average decrease in pain score of 1.1 (median 0, IQR 0 to 3, p < 0.01). Time-series analysis showed modest increases in prehospital and hospital pain assessment documentation and prehospital analgesic documentation. Our study demonstrates that prehospital pain assessment, management, and documentation remain primary targets for performance improvement on the battlefield. Results of paired prehospital to hospital pain scores and time-series analysis demonstrate both feasibility and benefit of prehospital analgesics. Future efforts must also include an expansion of the prehospital battlefield analgesic formulary. C1 [Gerhardt, Robert T.] Brooke Army Med Ctr, Emergency Med, San Antonio, TX 78234 USA.

The quadrotor needs to be tracked by the ground robot with a monocular camera, and hence its motion should facilitate the ground vision-based tracking process by remaining in the effective camera sensing area. We design a model predictive controller (MPC) strategy where the visibility constraints of the camera and the control input constraints of the quadrotor are encoded into the cost function via barrier functions, and we adopt a fast MPC solver that is able to solve the optimization problem in real time. We also propose a method to enhance the robustness of the algorithm by suitably defining a restart method for the MPC solver. The applicability of the proposed algorithm is demonstrated through simulations and experimental results on real setups.

Quantization occurs in many applications and systems and can usually be neglected in cases where the quantization interval is small. If this is not the case, the quantization effects cannot be ignored, and the nonlinearity induced by the quantizer must be addressed. Particle filters can be used, but are computationally expensive. Recently, the Tobit Kalman filter has been used to provide estimates when the measurement is a piecewise nonlinear censored regression model. The Tobit Kalman filter for quantized measurements derived in this paper is a computationally efficient algorithm, which converges to the optimal Kalman filter when quantization intervals become small. The derived estimator is compared to the Cramer Rao lower bound and the particle filter. C1 [Allik, Bethany] US Army Res Lab, Aberdeen Proving Ground, MD 21005 USA.

These communication technologies are complementary and by coordinating them it is possible to mitigate their respective weaknesses. A challenging problem is positioning the flying robot within optical communication range, especially when the distance is large and the sensor location is unknown. In this work, we propose a solution to the problem of autonomously localizing the sensor node relative to the aerial vehicle. We take advantage of the hybrid communication scheme by developing a control strategy that uses the radio signal to guide the aerial platform to the sensor node. Once the optical-based signal strength is over a desired threshold the robot hovers within optical range. The control strategy is demonstrated through simulations that incorporate a realistic model for the hybrid communication link.

The contextual deep CNN first concurrently applies multiple 3-dimensional local convolutional filters with different sizes jointly exploiting spatial and spectral features of a hyperspectral image. The initial spatial and spectral feature maps obtained from applying the variable size convolutional filters are then combined together to form a joint spatio-spectral feature map. The joint feature map representing rich spectral and spatial properties of the hyperspectral image is then fed through fully convolutional layers that eventually predict the corresponding label of each pixel vector. The proposed approach is tested on two benchmark datasets: the Indian Pines dataset and the Pavia University scene dataset. Performance comparison shows enhanced classification performance of the proposed approach over the current state of the art on both datasets.

We describe an experiment designed to investigate the impact of the identity, presentation form, and perspective of a virtual storyteller on a human user who engages in a story-swapping activity with two virtual characters. For each interaction, the user was given 10 "ice-breaker" questions to ask a virtual character and respond to the character's reciprocal request. Participants also filled out a post-interaction survey, measuring rapport with the character and impressions of the character's personality. Results generally show that participants prefer characters who tell first person stories, however there were some interactions with presentation order. No significant preferences were established for the form or identity variables.

Specialized agents at the source need to process unstructured, ad-hoc queries, identifying both the context and the intent to determine the implied task. Knowing the task will allow the distributed agents that service the requests to filter, summarize, or transcode data prior to responding, lessening the network impact. This paper describes an approach that uses natural language processing (NLP) techniques, multi-valued logic based inferencing, distributed intelligent agents, and task-relevant metrics for information retrieval.

For the first phase of our research reported here, wizards play the role of dialogue manager, acting as a robot's dialogue processing. We describe a novel step within WOz methodology that incorporates two wizards and control sessions: the wizards function much like corpus annotators, being asked to make independent judgments on how the robot should respond when receiving the same verbal commands in separate trials. We show that inter-wizard discussion after the control sessions and the resolution with a reconciled protocol for the follow-on pilot sessions successfully impacts wizard behaviors and significantly aligns their strategies. We conclude that, without control sessions, we would have been unlikely to achieve both the natural diversity of expression that comes with multiple wizards and a better protocol for modeling an automated system.

Models of neuronal networks allow scientists to explore the impact of differential neuronal connectivity using analysis techniques and information not available experimentally. However, modeling realistic neurobiological processes and encoding them in computer simulations is challenging, as increasing computing and data requirements are all of concern. In this work we study the performance of neocortex simulations using GEneral NEural SImulation System (GENESIS), a well-known multi-function brain simulation package, supported by high performance computing resources. The contribution of our work is threefold. First, we study the impact of platforms (i.e., single fat nodes versus high-end clusters) and their features on the performance and data generation for a small scale model of neocortex. Second, we assess the impact of the model complexity (i.e., number of cells and cell connectivity) on the performance and data generation for increasingly large versions of the neocortex model on high-end clusters. Third, we provide selected scientific results obtained by increasing the model complexity. We show that the more realistic and rigorous modeling of neocortex functions is computationally feasible but requires high performance computing resources to mitigate the growing computing and data requests of the associated simulations.

MCONF, which was developed in an earlier work, enables mass configuration changes in a MANET using multiple modes of operation based on the underlying network scenario. However, MCONF relies on classic flooding approach to disseminate configuration changes and gather feedback information to/from nodes. In this paper we propose: S-MCONF - a Simple Mass Configuration protocol focusing on efficiency, and E-MCONF - an Efficient Mass Configuration protocol focusing on reliability. Both of these are developed based on MCONF while utilizing underlying efficient broadcasting framework that computes a Minimum Connected Dominating Set (MCDS) to forward messages in a MANET. Our proposed S-MCONF and E-MCONF protocols utilize three different relay selection algorithms, namely Essential Connecting Dominating Set (E-CDS), Source based MultiPoint Relay (S-MPR) and Non-source specific MultiPoint Relay (NS-MPR), to optimize performance. We evaluate the performance of our S-MCONF and E-MCONF protocols by emulating MANET on Common Open Research Emulator (CORE) for dynamic topologies based on mobility of nodes. Performance is measured in terms of reliability and packet redundancy. Based on our findings as part of the study, it is observed that S-MCONF is very well suited for low node mobility scenarios in the MANETs. On the other hand, E-MCONF provides reliability of packet delivery in MANETs even for high node mobility scenarios. Both S-MCONF and E-MCONF are able to improve their packet efficiency significantly at low mobility as compared to MCONF protocol.

Deception in the cyber domain poses an immensely difficult challenge for states to differentiate between espionage activities in cyberspace and cyber attacks. The inability to distinguish between cyber activities places US cyber infrastructure in a perilous position and increases the possibility of a disproportionate or inadequate response to cyber incidents.

Existing analytic training teaches analysts about common cognitive biases and then aims to correct them with structured analytic techniques. On its face, this approach is eminently reasonable; on close inspection, incomplete and imbalanced. Current training is anchored in a mid-twentieth century understanding of psychology that focuses on checking over-confidence and rigidity but ignores the problems of under-confidence and excessive volatility. Moreover it has never been validated against objective benchmarks of good judgment. We propose a new approach: (a) adopting scientifically validated content and regularly testing training to avoid institutionalizing new dogmas; (b) incentivizing analysts to view training guidelines as means to the end of improved accuracy, not an end in itself.

However, a major challenge for this approach is the development of a stable and active interfacial region (i.e., junction) that adjoins the CEM and AEM layers. Moreover, a fundamental understanding of transport at the CEM-AEM junction is lacking. Therefore, the present study focuses on the theoretical development and analysis of the nature of the BPM interface. A Poisson-Nernst-Planck (PNP) theory is formalized and applied to a representative BPM interface. The findings are reported in terms of bias (i.e., overpotential) in a galvanic device with respect to CEM and AEM material requirements. Specific attention is paid to our interests in the application of the BPM to a fuel cell device with an acidic (CEM) anode and alkaline (AEM) cathode. We demonstrate that a BPM with an acidic CEM anode and alkaline AEM cathode must promote a trap-assisted type of recombination mechanism under forward bias. Without such a mechanism, large overpotentials are needed to drive ionic recombination processes. (C) The Author(s) 2016. Published by ECS. All rights reserved.

We present a simpler methodology, suitable for widespread adoption of FTIR QA as a standard laboratory technique across disciplines by occasional users. Algorithm is straightforward and intuitive, yet it is also fast, accurate, and robust. Relies on component spectra, minimization of errors, and local adaptive mesh refinement. Tested successfully on real mixtures of up to nine components. We show that our methodology is robust to challenging experimental conditions such as similar substances, component percentages differing by three orders of magnitude, and imperfect (noisy) spectra. As examples, we analyze biological, chemical, and physical aspects of bio-hybrid fuel cells. Published by Elsevier B.V.

Although more than 60 tools have been developed, there is no systematic evidence-based comparison with regard to their strength and weakness, especially in terms of correction accuracy. Here we report a full factorial simulation study to examine how NGS dataset characteristics (genome size, coverage depth and read length in particular) affect error correction performance (precision and F-score), as well as to compare performance sensitivity/resistance of six k-mer spectrum-based methods to variations in dataset characteristics. Multi-way ANOVA tests indicate that choice of correction method and dataset characteristics had significant effects on performance metrics. Overall, BFC, Bless, Bloocoo and Musket performed better than Lighter and Trowel on 27 synthetic datasets. For each chosen method, read length and coverage depth showed more pronounced impact on performance than genome size. This study shed insights to the performance behavior of error correction methods in response to the common variables one would encounter in real-world NGS datasets. It also warrants further studies of wet lab-generated experimental NGS data to validate findings obtained from this simulation study.

Such predictions are a critical component of any modern control approach that utilizes uncertainty information to provide robustness in control design. We use an online learning algorithm based on matrix factorization techniques to fit a statistical model of error that provides enough expressive power to enable prediction directly from motion control signals and low-level visual features. Moreover, we empirically demonstrate that this technique compares favorably to predictors that do not incorporate this information.

Some of these environments are so complex that they preclude persistent, nearby operator oversight. This absence of oversight motivates the need for an online monitoring system, specifically for robots operating in difficult environments. We develop a test methodology and set of online monitoring metrics by extending methods for characterizing robotic-systems using offline metrics. We implement this test methodology in an unstructured, outdoor environment and show the resulting performance information gained from our online monitoring solution. This online monitoring approach is generalizable such that it characterizes any robotic system that meets our set of hardware and software criteria.

Small insects like cockroaches can rapidly right themselves when upside down, yet small fast-running legged robots are much less capable of ground-based self-righting. Inspired by the discoid cockroach that opens its wings to push against the ground to self-right, we designed actuated wings for robot self-righting based on recently-developed rounded shells for obstacle traversal In We measured the self-righting performance of a robot using these actuated wings, and systematically studied the effects and trade-offs of wing opening magnitude, speed, symmetry, and wing geometry. Our study provided a proof-of-concept that robots can take advantage of an existing body structure (rounded shell) in novel ways (as actuated wings) to serve new locomotor functions, analogous to biological exaptations [2]. Our results demonstrated that the robot self-rights dynamically, with active wing pushing followed by passive falling, and benefits from increasing kinetic energy by pushing faster and longer. Our experiments also showed that opening both wings asymmetrically increases righting probability at low wing opening magnitudes. C1 [Li, Chen] Johns Hopkins Univ, Baltimore, MD 21218 USA.

Rapid Serial Visual Presentation (RSVP) is one well-established technique that has shown promise integrating human perception into a machine perception system. In this paper, we apply computer vision techniques to image data filtered through human RSVP. We introduce "task conversions" to integrate the two modalities, applying the precise localization capabilities of computer vision with the detection capabilities of RSVP. We employ naive Bayesian fusion and a novel method, dynamic belief fusion (DBF), in a joint scheme as fusion approaches. Preliminary experiments demonstrate that DBF extracts complementary information from both human and machine sources to improve performance for both target classification and object detection.

Supervised visual classifiers are typically trained with large sets of images, hand annotated by humans with region boundary outlines followed by label assignment. This annotation is time consuming, and unfortunately, a change in environment requires new or additional labeling to adapt visual perception. The time is takes for a human to label new data is what we call adaptation latency. High adaptation latency is not simply undesirable but may be infeasible for scenarios with limited labeling time and resources. In this paper, we introduce a labeling framework to the environment perception domain that significantly reduces adaptation latency using unsupervised learning in exchange for a small amount of label noise. Using two real-world datasets we demonstrate the speed of our labeling framework, and its ability to collect environment labels that train high performing multi-concept classifiers. Finally, we demonstrate the relevance of this label collection process for visual perception as it applies to navigation in outdoor environments.

Offering affordable agility and maneuverability, multi-rotor aircrafts have become the most commonly used platforms for robotics applications. Amongst the most promising applications are inspection of power-lines, cell-towers, large and constrained infrastructures and precision agriculture. While GPS offers an easy solution for outdoor autonomy, using on-board sensors is the only solution for autonomy in constrained indoor environments. In this paper, we present our results on autonomous inspection of completely dark, featureless, symmetric dam penstocks using cameras and range sensors. We use a hex-rotor platform equipped with an IMU, four cameras and two lidars. One of the cameras tracks features on the walls using the on-board illumination to estimate the position along the tunnel axis unobservable to range sensors while all of the cameras are used for panoramic image construction. The two lidars estimate the remaining degrees of freedom (DOF). Outputs of the two estimators are fused using an Unscented Kalman Filter (UKF). A moderately trained operator defines waypoints using the Remote Control (RC). We demonstrate our results from Carters Dam, GA and Glen Canyon Dam, AZ which include panoramic images for cracks and rusty spot detection and 6-DOF estimation results with ground truth comparisons. To our knowledge ours is the only study that can autonomously inspect environments with no geometric cues and poor to no external illumination using MAVs.

These methods enjoy strong convergence and have manageable memory requirements. Implicitly-restarted Lanczos methods naturally find approximations to both the largest and smallest eigenpairs of the input matrix, but stagnation of Ritz values may lead to slow convergence, especially when one only wants eigenvalues from one end of the spectrum and memory is constrained. We develop a filtering strategy that breaks Ritz value stagnation for these one-sided eigenvalue problems. We demonstrate the reduction in matrix-vector product costs and note that this new variant has marked advantages when memory is constrained and when matrix-vector products are expensive.

While current research has put a strong focus on detecting events, there is no clear guidance on how those storylines should be processed such that they would make sense to a human analyst. In this paper, we present DISTL, an event processing platform which takes as input a set of storylines (a sequence of entities and their relationships) and processes them as follows: (1) uses different algorithms (LDA, SVM, information gain, rule sets) to identify events with different themes and allocates storylines to them; and (2) combines the events with location and time to narrow down to the ones that are meaningful in a specific scenario. The output comprises sets of events in different categories. DISTL uses in-memory distributed processing that scales to high data volumes and categorizes generated storylines in near real-time. It uses Big Data tools, such as Hadoop and Spark, which have shown to be highly efficient in handling millions of tweets concurrently.

However, traditional design processes applied to SUAS produce a single design for a single set of requirements. Off-design mission performance is often greatly degraded due to the vehicle's small scale. This paper considers a different approach to SUAS design aimed at addressing this issue. In this approach, a hybrid modular and scalable product family is coupled with linked engineering analyses in order to automatically formulate a design given a set of mission requirements. This allows multiple SUAS designs to be rapidly synthesized from multiple sets of design requirements using a common set of components. Designs are then rapidly generated and manufactured "on-demand" using automated manufacturing techniques in order to address unforeseen mission needs. The design approach, named "Aggregate Derivative Approach to Product Design" (ADAPt Design), consists of four actions: (1) requirements analysis, (2) architecture selection, (3) interface design, and (4) concept refinement and design. The outcomes of the method are a family of designs which are highly compatible with design automation, and a toolset that automatically translates changes in requirements to changes in detailed 3-D models. Results of the application of this approach are presented via the design of several SUAS. The capability of the design paradigm is assessed through a comparison of design requirements to the measured performance of the designed vehicle, and conclusions are drawn about the approach's applicability and scalability.

However, the simulation model could be biased. Accordingly, when the conventional RBDO design is manufactured, the product may not satisfy the target reliability. Therefore, model validation, which corrects model bias, should be integrated in the RBDO process by incorporating experimental data. The challenge is that only a limited number of experimental data is usually available due to the cost of actual product testing. Consequently, model validation for RBDO needs to account for the uncertainty induced by insufficient experimental data as well as variability inherently existing in the products. In this paper, a confidence-based model validation process that captures the uncertainty and corrects model bias at user-specified target conservativeness level is developed. Thus, RBDO can be performed using confidence-based model validation to obtain conservative RBDO design. It is found that RBDO with model bias correction becomes a moving-target problem because the feasible domain changes as the design moves. Consequently, the RBDO optimum may not be easily found due to the convergence problem. To resolve the issue, an efficient process is proposed by carrying out deterministic design optimization (DDO) and RBDO without validation, followed by RBDO with confidence-based model validation. Finally, we demonstrate that the proposed RBDO approach can achieve a conservative and practical optimum design given a limited number of experimental data. C1 [Moon, Min-Yeong; Choi, K.

However, the independent input variable and the constant STD may not correctly describe reliability problems because, for certain problems, the input variable is correlated, and its STD varies as the mean changes. For this kind of design problem, the input correlation should be considered, and the input STD should be changed as the design iteration proceeds and the corresponding design variable - the input mean - changes. Specifically, the varying input STD causes the input variability to fluctuate so that the probability of failure (PoF) of the design becomes a moving target. Hence, RBDO with varying input STD suffers difficulty in convergence unless accurate design sensitivity is available. In sensitivity-based RBDO, the sensitivity for the most probable point (MPP) search and the design sensitivity of probabilistic constraints are required. In this paper, it is found that the input correlation significantly affects the sensitivity for the MPP search and that the varying STD has large impact on the design sensitivity for RBDO. Therefore, sensitivities considering both the input correlation and the varying input STD have been developed for an efficient and effective optimization process. For the reliability analysis method, the enriched performance measure approach (PMA+) is used, as it is efficient and more stable during the RBDO process. To represent the input correlation, a copula is used in the sensitivity derivations. Using a mathematical example, the accuracy and efficiency of the developed sensitivities are verified. The RBDO result for the mathematical example indicates that the developed methods provide accurate sensitivities in the optimization process. C1 [Cho, Hyunkyoo; Choi, K.

A series of drop tower tests were conducted on twelve models of blast energy-attenuating (EA) seats to determine the effects of vertical accelerative loading on ground vehicle occupants. Two previous technical publications evaluated specific aspects of the results of these drop tower tests on EA seats containing the three sizes of anthropomorphic test devices (ATDs) including the Hybrid III 50th percentile female, the Hybrid III 50th percentile male, and the Hybrid III 95th percentile male. The first publication addressed the overall trends of the forces, moments, and accelerations recorded by the ATDs when compared to Injury Assessment Reference Values (IARVs), as well as validating the methodology used in the drop tower evaluationsl. Review of ATD data determined that the lumbar spine compression in the vertical direction could be used as the "go/no-go" indicator of seat performance. The second publication assessed the quantitative effects of Personal Protective Equipment (PPE) on the small occupant, as theaddition of a helmet and Improved Outer Tactical Vest (IOTV) with additional gear increased the weight of the 5th percentile female ATD more than 50%(2). Comparison of the loading data with and without PPE determined that the additional weight of PPE increased the overall risk of compressive injury to the lumbar and upper neck of the small occupant during an underbody blast event. Using the same data set, this technical paper aimed to evaluate overall accelerative loading trends of the 5th percentile female ATD when compared to those of the 50th percentile male ATD in the same seat and PPE configuration. This data trend comparison was conducted to gain an understanding of how seat loading may differ with a smaller occupant. The focus of the data analysis centered around the lumbar spine compression, as this channel was the most likely to exceed the IARV limit for the 5th percentile female ATD. Based on the previous analysis of this data set, the lightest occupant trends showed difficulty in protecting against lumbar compression injuries with respect to the 5th percentile female's IARV, whereas the larger occupants experienced fewer issues in complying with their respective IARVs for lumbar compression. A review of pelvis acceleration was also conducted for additional kinetic insight into the motion of the ATDs as the seat strokes. This analysis included a review of how the weight and size of the occupant may affect the transmission of forces through a stroking seat during the vertical accelerative loading impulse.

This is possible by exploiting the redundancy of the drive system to generate additional yaw moment and to maximize the utilization of individual tire-road contacts without significant extra power consumption by the drive motors. This paper aims at improving the efficiency of torque allocation with the addition of active steering while enhancing the dynamic performance of the independent hub motor driven multi-axle vehicles. The control algorithm outlined here employs a two level scheme. The higher level computes the desired global control efforts that are needed to track the reference yaw rate and slip angle state responses generated by a reference vehicle model, and the lower level executes optimal control allocation with a cost function that simultaneously takes into account I) maximization of the tire utilization on all axles considering dominant tire nonlinearities, and 2) minimization of the actuation efforts of the active steering system and the distributed motor torques. The validity of the proposed algorithm is verified via comparison of the simulations of the control allocation scheme applied to a high fidelity multi-axle vehicle under several aggressive test maneuvers with different actuation configurations. The results suggest that the addition of active steering provides lower actuator power consumption and tire usage while ensuring enhanced lateral and longitudinal dynamic performance for the vehicle.

GP ASME TI INSTRUMENTING A FLAPPING WING AIR VEHICLE SYSTEM FOR FREE FLIGHT MEASUREMENT SO PROCEEDINGS OF THE ASME INTERNATIONAL DESIGN ENGINEERING TECHNICAL CONFERENCES AND COMPUTERS AND INFORMATION IN ENGINEERING CONFERENCE, 2016, VOL 5A LA English DT Proceedings Paper CT ASME International Design Engineering Technical Conferences and Computers and Information in Engineering Conference (IDETC/CIE) CY AUG 21-24, 2016 CL Charlotte, NC SP ASME, Design Engn Div, ASME, Computers & Informat Engn Div ID ANIMAL FLIGHT; BIRDS AB Flapping wing flight is a challenging system integration problem for designers due to tight coupling between propulsion and flexible wing subsystems with variable kinematics. Due to the fluid-structure interactions present in such a system, models must be tailored to a particular design instantiation to provide high accuracy and a clear picture of underlying physical phenomena. However, a practical design approach requires an extensible model that enables exploration of several design alternatives. The difficulty of generating models that are both highly accurate and extensible suggest a combined experimental and simplified modeling approach may offer a more tractable approach to system design and integration. However, experimental data on flapping wing air vehicles that is collected in a static laboratory test or a wind tunnel test is limited because of the rigid mounting of the vehicle, which alters the natural body response to flapping forces generated. Therefore, we undertake the design of a flapping wing air vehicle system that is instrumented to provide data that may be used to create and validate a simplified aerodynamics model that is capable of freely flying. The sensor suite includes measurements of attitude, heading, altitude, position, wing angle, as well as voltage and current supplied to the drive motors. With this approach, a complete energetic picture of flight is constructed, and by varying the parameters of the vehicle, the envelope of feasible performance is investigated. Finally, the results of the experimental testing are compared to a simplified aerodynamic model to establish the effectiveness of the proposed approach to system design.

To this end, a continuum soil model using multiplicative plasticity theory with Drucker-Prager failure criterion is integrated with the high-fidelity flexible tire model developed using the shear deformable laminated composite shell elements for deformable tire/terrain interaction simulation. The element locking of the standard 8-node brick element caused by the tri-linear polynomial can be alleviated by introducing an additional node defining the second derivative of the global position vector at the center of the element, allowing for describing the linear strain distribution over the element volume without introducing enhanced assumed strain (EAS). The benchmark test result indicates that the identical rate of convergence to that of the locking-free 8-node brick element with 9-parameter EAS is obtained using the brick element presented in this study. Since the constitutive equation for soil models is highly nonlinear in nature, involving iterative return mapping algorithm to find the plastic strain every time step, elimination of EAS using the 9 node brick element leads to straightforward implementation for soil model and computationally efficient procedure for tire/soil interaction simulation. Numerical example of deformable tire and terrain interaction simulation is presented to demonstrate the numerical procedure developed in this study.

Complex systems are marked by high level of ambiguity, uncertainty, and emergence. These conditions impose challenges and difficulties for practitioners responsible to successfully manage and design complex systems. There is a fundamental need to have a cadre of individuals who are capable of dealing with increasingly complex systems and their problems. One response is Systems Thinking, which can provide a holistic thinking paradigm that opens new channels and opportunities to think differently about complex systems as a whole unit. This paradigm will enable individuals to avoid solving the wrong problems. The emphasis of this paper is to explore possible applications of a research-based instrument developed to capture the level of systems thinking for individuals who engage and design complex systems. The Systems Thinking Profiles produced by the instrument represent individual inclination to adapt a systemic perspective for engaging and solving complex system problems, and reflects a state that can be enhanced through training and/or education to improve capacity for systems thinking.

A multi-layer feedforward network with backpropagation learning is used as the model framework. The model is trained, tested, and validated using 5100 student samples with data compiled from admissions records and institutional research databases. Nine input variables consist of categorical and numeric data elements including: high school rank, high school quality, standardized test scores, high school faculty assessments, extra-curricular activity score, parent's education status, and time since high school graduation. These inputs and the multi-layer neural network model are used to classify students as: graduates, late graduates, or non-graduates. Several neural network architectures are examined and compared by run time, minimum mean square error achieved (MSE), mean correct classification rate, precision, recall, and specificity. A multi-layer neural network with 50 hidden neurons, momentum value of 0.8, and learning rate of 0.1, with hyperbolic tangent hidden neuron activation functions was able to accurately predict graduation success and achieved the best performance with classification accuracy exceeding 95%, high recall, high precision, and high specificity. This prediction model may be used to inform admission decisions and identify opportunities for required remediation with the potential to improve graduation rates, increase student retention, reduce late graduation, and reduce first-term course failures.

Within the approach, the system's structure, behavior, requirements, and parametrics are defined as elements within an integrated model. System Engineers use nine SysML diagrams to display unique views of these system elements. A significant limitation of SysML is that it is only descriptive in nature and cannot produce analytical results to inform system effectiveness. In order to achieve the full benefit of the MBSE approach the systems engineering community must also rely on external models that capture more sophisticated analysis across a wide variety of domains. These domain models include simulations that measure operational effectiveness, life cycle costing models, physics-based computational simulations, manufacturing models, and many more. The purpose of this paper is to propose an approach that integrates these external simulation models with the MBSE integrated model using statistical metamodels that act as surrogates to the simulations. We demonstrate the approach using a simple system design problem and an agent-based simulation. (C) 2016 Published by Elsevier B.V.

Ras Labs Synthetic Muscle (TM) - electroactive polymers (EAPs) that contract and expand at low voltages - which mimic the unique gentle-yet-strong nature of human tissue, is a potential asset to manned space travel through protective gear and human assist robotics and for unmanned space exploration through deep space. Generation 3 Synthetic Muscle T was proven to be resistant to extreme temperatures, and there were indications that these materials may also be radiation resistant. The purpose of the Ras Labs-CASIS-ISS Experiment is to test the radiation resistivity of the third and fourth generation of these EAPs, as well as to make them even more radiation resistant or radiation hardened. On Earth, exposure of the Generation 3 and Generation 4 EAPs to a Cs-137 radiation source for 47.8 hours with a total dose of 305.931 kRad of gamma radiation was performed at the US Department of Energy's Princeton Plasma Physics Laboratory (PPPL) at Princeton University, followed by pH, peroxide, Shore Hardness Durometry, and electroactivity testing to determine the inherent radiation resistivity of these contractile EAPs and to determine whether the EAPs could be made even more radiation resistant through the application of appropriate additives and coatings. The on Earth preliminary tests determined that selected Ras Labs EAPs were not only inherently radiation resistant, but with the appropriate coatings and additives, could be made even more radiation resistant. G-force testing to over 10 G's was performed at US Army's ARDEC Labs, with excellent results, in preparation for space flight to the International Space Station National Laboratory (ISS-NL). Selected samples of Generation 3 and Generation 4 Synthetic Muscle (TM), with various additives and coatings, were launched to the ISS-NL on April, 14 2015 on the SpaceX-6 payload, and will return to Earth in 2016. The most significant change from the on Earth radiation exposure was color change in the irradiated EAP samples, which in polymers can be indicative of accelerated aging. There was visible yellowing in the irradiated samples compared to the control samples, which were not irradiated and were clear and colorless. On Earth, surface motion analysis for speed of onset of actuation after electric input at the nano-level on selected Synthetic Muscle (TM) samples was determined using high speed digital photography. While the Synthetic Muscle Experiment is in orbit on the ISS-NL, photo events occur every 4 to 6 weeks to observe any changes, such as color, in the samples. The bulk of the testing will occur when these EAP samples return back to Earth, and will be compared to the duplicate experiment that remains on Earth (the control experiment). Newly developed fifth generation Synthetic Muscle (TM) EAPs, in addition to being electroactive and shape-morphing, are also extremely impact resistant. These Generation 5 EAPs were tested at the nanometer level for exact speed of onset following electric input, with start of electro-actuation within 20 milliseconds. Smart electroactive polymer based materials and actuators promise to transform prostheses and robots, allowing for the treatment, reduction, and prevention of debilitating injury and fatalities, and to further our exploration by land, sea, air, and space.

Their practical application, however, has been prevented by the poor electrochemical stability of aqueous electrolytes, which severely restricts the choice of anode and cathode materials for such batteries and leads to low energy densities. It has been demonstrated that "water-in-salt'' electrolytes can provide an expanded voltage window of similar to 3.0 V, which can accommodate electrode materials that were otherwise forbidden in conventional aqueous electrolytes. In this study, we showed that the presence of an additive could further stabilize the aqueous electrolyte at a high voltage cathode surface. By forming a cathode electrolyte interphase (CEI) through electrochemical oxidation of tris(trimethylsilyl) borate (TMSB), we successfully stabilized LiCoO2 in water-in-salt electrolyte at a high cut-off voltage that corresponds to 0.7e electron charge transfer. To the best of our knowledge, this is also the first electrolyte additive known to form an interphase in aqueous electrolytes. The formed CEI significantly suppressed electrolyte oxidation as well as cobalt dissolution from LiCoO2 into electrolytes, allowing LiCoO2 to be stably charged/discharged at a higher cut-off voltage with a high capacity utilization of 170 mA h g(-1). When paired with an Mo6S8 anode, the 2.5 V aqueous full cell delivered a high energy density of 120 W h kg(-1) for 1000 cycles with an extremely low capacity decay rate of 0.013% per cycle.

GP IEEE TI CLUSTERING-AWARE STRUCTURE-CONSTRAINED LOW-RANK REPRESENTATION MODEL FOR LEARNING HUMAN ACTION ATTRIBUTES SO 2016 IEEE 12TH IMAGE, VIDEO, AND MULTIDIMENSIONAL SIGNAL PROCESSING WORKSHOP (IVMSP) LA English DT Proceedings Paper CT 12th IEEE Image, Video, and Multidimensional Signal Processing Workshop (IVMSP) CY JUL 11-12, 2016 CL Bordeaux, FRANCE SP IEEE ID ALGORITHM; RECOGNITION; DISTANCE AB This paper addresses the problem of learning meaningful human action attributes from high-dimensional video sequences based on union-of-subspaces (UoS) model. The model hypothesizes that each action attribute is represented by a subspace. It puts forth an extension of existing low-rank representation (LRR), termed the clustering-aware structureconstrained low-rank representation (CS-LRR) model, for unsupervised learning of human action attributes. The proposed CS-LRR model overcomes the shortcomings of existing techniques by its ability to handle disjoint subspaces, and by performing optimal spectral clustering of the subspaces. An efficient linear alternating direction method (LADM) is developed to solve the CS-LRR optimization problem. A human action or activity is represented as a sequence of transitions from one action attribute to another and can be uniquely represented by a subspace transition vector. These subspace transition vectors are used for human action recognition. The effectiveness of the proposed model is demonstrated through experiments on two real-world datasets for action recognition.

In addition to the usual key-press and key-release timing features available from mechanical keyboards, the touchscreen features also included pressure, screen location, accelerometer, and gyroscope information. Short numeric input data, ten-digit numeric strings, were collected from 52 participants on identical Android smartphones. Several user authentication biomefric experiments were performed on these data to measure overall system performance and to quantify the biomefric value of various feature subsets. Two validation procedures (repeated random sub-sampling and leave-one-out cross-validation) and two distance metrics (Euclidean and Manhattan) were compared in the study, and the best results were compared to previous keystroke biomefric studies. The best equal-error-rate performances on the key-press/release timing features, the touchscreen features, and all features combined were 19.7%, 4.0%, and 3.9%, respectively. Of the various touchscreen feature subsets, the gyroscope features performed best with an equal error rate of 4.3% C1 [Coakley, Michael J.; Tappert, Charles C.] Pace Univ, CSIS, Seidenberg Sch, Pleasantville, NY 10570 USA.

GP IEEE TI Crossing Domains with the Inductive Transfer Encoder: Case Study in Keystroke Biometrics SO 2016 IEEE 8TH INTERNATIONAL CONFERENCE ON BIOMETRICS THEORY, APPLICATIONS AND SYSTEMS (BTAS) SE International Conference on Biometrics Theory Applications and Systems LA English DT Proceedings Paper CT 8th IEEE International Conference on Biometrics - Theory, Applications and Systems (BTAS) CY SEP 06-09, 2016 CL Niagara Falls, NY SP IEEE, NVIDIA, Safran Ident & Secur, Cognitec, IBM Res, Progeny Syst Corp, IEEE Biometr Council AB Keystroke biometric samples are often collected under various conditions, such as different device types, increasing levels of practice through repetition, and subject impairment. Cross-domain comparisons, in which query samples are collected under different conditions than the template, generally lead to degraded performance. The difficulty in comparing samples from different domains can be viewed as an inductive transfer learning problem, in which general knowledge of the mapping between a source and target domain can be applied to increase task performance, such as verification accuracy, by transferring source domain samples to the target domain. In this light, we propose the inductive transfer encoder, which utilizes pairwise correspondences from an independent dataset to learn a general transformation between domains. When the transformation is applied to template samples in the source domain, and query samples are in the target domain, increased verification performance is observed. We evaluate four different strategies for establishing the pairwise correspondences between source and target domains, and two cross-domain problems: low vs high practice levels and one vs two typing hands. Empirical results demonstrate that the inductive transfer encoder captures general rules that can be applied to transfer source domain samples to the target domain.

Despite the challenging task, we effectively demonstrate the ability to produce a visible image from a probe polarimetric-thermal image. Moreover, we are able to demonstrate the same capability with conventional thermal imagery, but we report a significant improvement by incorporating polarization-state information.

The advantage of harmonic radar is that it can separate linear clutter from the harmonic target response. Possible disadvantages of harmonic radar include the need for highly sensitive receiver components, which can result in degraded performance in the presence of radio frequency interference (RFI). The authors have previously investigated multiple spectrum sensing techniques for harmonic radar. In this paper, an overview of these techniques are presented. These techniques mitigate the impact of RFI on harmonic radar performance, require a low computational complexity so that an up-to-date measure of the RFI is known, and are applicable to multiple radar types.

The vast majority of that portfolio is earthen structures. Findings from the assessments have shown that the major risk drivers for these earth structures are related to erosion (internal and external), overtopping, poorly designed and constructed intrusions (such as pipe crossings), and other factors to a lesser degree (such as burrowing animals). Therefore, the US ACE is currently investigating several of these failure modes with emphasis on internal and external erosion. This paper will highlight efforts to investigate surface erosion, which may lead to breach formation and growth, by use of laboratory scale model testing to understand and properly capture the physics of the problem. These data are informing improvement and development of numeral methods for use in ongoing risk assessments.

However, software to directly support these requirements has not been available. The current software used within USACE to perform these types of analyses, HEC-FDA (Flood Damage Reduction Analysis), has a number of limitations. For this reason and others, USACE's Hydrologic Engineering Center (CEIWR-HEC) developed the Watershed Analysis Tool (HEC-WAT). HECWAT was initially developed to assist USACE personnel conduct water resources studies of complex riverine systems with an integrated, comprehensive and systems based approach. However, since USACE also requires a life-cycle analysis, CEIWR-HEC added capability through the Flood Risk Analysis (FRA) compute option that allows risk analysis computations while incorporating a life-cycle approach. HEC-WAT/FRA includes systems and life-cycle approaches, event-based sampling, parameter sampling, and the ability to do scenario and alternative analyses. Applications of the FRA compute include levee certification studies, dam and levee safety studies, and planning and design studies. This paper will introduce HEC-WAT/FRA, describe scientific advancements included within it and provide applications to demonstrate how it will advance USACE modeling approaches.

A related topic concerns evacuation and emergency management (EEM). The magnitude of life loss is directly influenced by the effectiveness of EEM. Different models can be used to define the effectiveness of evacuation. The main objective of this study is to compare Dutch and American methods for evacuation as part of flood risk management strategies for a number of case studies in the US. A second, additional objective is to explore how approaches for EEM that have been recently developed in the Netherlands, can be applied in the United States. This research shows the benefits and limitations for the application of different types of models. This research contributes to the improvement of methods for emergency management, in the Netherlands, the US and other countries. C1 [Kolen, B. (Bas); Maaskant, B.

These relationships are described using paired data relationships of depth and damage. Generally, the curves utilized are based on an Elicitation of Experts (EoE). This paper will present an alternative methodology which takes empirical data of damage and depth, stratified by building classifications, and use Non Linear Least Squares Estimation to fit a parameterized function to compute depth-damage estimates. The general function will be described, and the parameters will be discussed. Parameters include foundation height, ground elevation, percent damages below ground, number of stories, height of stories, maximum damage as a percent, and the beginning elevation for damage. The advantages of this approach include the ability to utilize empirical data, and the ability to change parameters based on building practices across the world. Additionally, the paper will illustrate a bootstrapping approach to the empirical data to assist in describing confidence limits around the parameterized functional depth damage relationship. A Figure (Figure 1) is provided to illustrate the output of the process. C1 [Lehman, Will] USACE, 209 Second St, Davis, CA 95616 USA. [Nafari, R.

By estimating the consequences, the benefits of existing and future flood risk management measures can be evaluated and compared. HEC-FIA utilizes geospatial datasets to help users build structure inventories and assign values and population per structure. Using this information and geospatially derived flood depth grids (provided by most hydraulic models), HEC-FIA estimates direct economic, indirect economic, agricultural, and life loss consequences for flood hazards. HEC-FIA can compute results for a single event in either deterministic mode or in uncertainty mode which utilizes a Monte Carlo approach. The user can define the uncertainties about any structure in the floodplain in many ways, and each has various impacts on the different consequence calculations. For example, foundation heights, structure values, and depth-damage relationships impact economic consequences, while foundation heights, warning issuance times, and fatality rates impact the life loss calculations. All of these parameters can be defined with uncertainty. HEC-FIA can also be linked into HEC-WAT (Watershed Analysis Tool) with the FRA (Flood Risk Analysis) compute option to randomize the hydraulic events being evaluated in HEC-FIA so that hydrologic, hydraulic, geotechnical, and economic uncertainties can all be represented and evaluated by alternative within the floodplain. This paper will describe how HEC-FIA can be utilized to help evaluate the indirect economic consequences for various alternatives within a floodplain. The computational methods for indirect economic losses utilize a Computable General Equilibrium model to describe the secondary and tertiary impacts of loss of service, loss of laborers, and reductions in demand for intermediary goods.

Water level range, magnitude of extremes, and frequency will all contribute to the stability, operation, and performance of a given project. Understanding which component of total water level or combination of components controls performance (and at what time scale) is critical to the design and evaluation of a project. Being aware of the different cross shore zones of total water level calculation and impacts informs exposure and impact assessments. Estimating future conditions over the project life recognizes that there will be both stationary and nonstationary contributions to the total water level (TWL) over time, necessitating the consideration of scenarios in project alternative development. An adaptive management approach provides a process for dealing with future uncertainties and involves developing plans that envisage a range of futures, incorporates ongoing monitoring, and permits transitions from one approach to another. Identifying thresholds beyond which stability or performance are adversely impacted is an important way to understand current and future vulnerability with respect to water levels, especially within the flood risk mission area. The USACE total water level Engineering Technical Letter (ETL) in development will guide how to evaluate total water levels for USACE coastal missions.

Accurate computation of the flood flow magnitude and timing associated with a levee breach remains one of the most difficult and uncertain components of levee risk analysis. Contemporary methods are largely empirical and approximate, introducing substantial uncertainty to the damage and life loss models. Levee breach progressions are often extrapolated to the final width and breach formation time based on limited experience with past breaches or using regression equations developed from a limited data base of dam failures. Physically based embankment erosion models could improve levee breach modeling. However, while several mechanistic embankment breach models are available, they were developed for dams. Several aspects of the levee breach problem are distinct, departing from dam breach assumptions. This study applies three embankments models developed for dam breach analysis (DL Breach, HR BREACH, and WinDAM C) to historic levee breaches with observed (or inferred) breach rates, assessing the limitations, and applicability of each model to the levee breach problem.

BEP has been shown, historically, to be the cause of approximately one third of all internal erosion related failures. As such, the probability of BEP is commonly evaluated as part of routine risk assessments for dams and levees in the United States. Currently, average gradient methods are predominantly used to perform these assessments, supported by mean trends of critical gradient observed in laboratory flume tests. Significant uncertainty exists surrounding the mean trends of critical gradient used in practice. To quantify this uncertainty, over 100 laboratory-piping tests were compiled and analysed to assess the variability of laboratory measurements of horizontal critical gradient. Results of these analyses indicate a large amount of uncertainty surrounding critical gradient measurements for all soils, with increasing uncertainty as soils become less uniform.

However, sandbag structures are labor intensive and time consuming to construct and may not always be the best choice when selecting a flood-fighting barrier. To compare different barriers, the U.S. Army Engineer Research and Development Center (ERDC) developed a standard protocol to evaluate flood-fighting structures. Rapid Deployment Flood Wall (RDFW), Portadam, and Hesco Bastion were selected for testing based on technical merit from proposals submitted by companies that manufacture barrier-type, flood-fighting products. A standard sandbag structure was also tested. The evaluation included time, ease, and cost of construction, performance under hydrostatic and wave loading, overtopping, debris impact, possible repair, reuse, environmental impact, and cost. The results of the evaluation showed that the RDFW performed well but is more expensive than the other structures and also not easy to disassemble. The Portadam was efficient under hydraulic loading but did not test well in the debris impact tests. The Hesco levee performed well except for the amount of seepage that was observed. The Hesco levee was later retested after the company improved the product, and much less seepage was observed during the retest. The sandbag levee failed during the overtopping test. These results provide the flood-fighting community with results that will assist in the selection of the product that best fits their need.

This political identity is itself a multi-dimensional concept shaped not only by the political ideology, practices and institutions established by the rebel organisation, but also by the relationship with the state and its political institutions. Far from functioning in a vacuum or isolated, rebel groups, especially when operating as alternative providers of governance, build multi-layered networks of relations with the state, the pre-existing traditional society institutions as well as with other domestic and international political actors. The study focuses specifically on two complex armed groups, Hezbollah and Hamas, relying on primary sources as well as in-depth fieldwork on these groups' socio-political institution (In this case field work refers to both in-depth direct observation of the groups' social networks and political infrastructures as well direct interviews and meetings with key stakeholders involved in the administration of those activities. The time-frame for the field work spans between 2008 and 2013). The research tracks their multiple interactions with the state through grassroots activism, institutional politics and governance. Despite their considerable differences, at their cores, both organisations operate in a liminal space between open war and fragile post-conflict setting; between grassroots activism and institutional politics; between armed resistance and political accommodation; and between competition and cooperation with the state. As such, they represent useful starting points to begin deconstructing and problematising existing dichotomies still prevalent in studying both rebel governance and rebel-to-political transitions, including the binary staten-on-state opposition. In doing so, the analysis highlights the importance of taking into account the often hybrid and multi-layered political legacies adopted by armed groups during wartime and their impact in shaping their political trajectories as well as the potential roles for these groups in post-conflict settings.

This includes damage precursor formation on fiber surfaces, within the matrix, and at the fiber-matrix interface/interphase. In this effort, we present a micro-/nano-scale technique for characterizing damage precursor formation on individual carbon fibers exposed to cyclic tensile loads. Nanoindentation and atomic force microscopy (AFM) were used to study the local properties of the individual microfibers before and after global loading events. An AFM image analysis was used to track evolution of topography on the fiber surfaces. The work is a first step toward understanding damage precursor formation in individual microfibers; the work is expected to enable multiscale composites modeling efforts as well as enable the development of future self-sensing materials.

The cantilever devices were fabricated on a silicon wafer using standard micro fabrication techniques, and may therefore be applicable to microelectromechanical systems (MEMS) switch or actuator applications. This paper details the development of a co-sputtering process to yield a SMA film with controllable composition of Ni50Ti50 and transformation temperature around 60 degrees C. Shape memory effects were characterized and verified using Differential Scanning Calorimetry (DSC), which demonstrated a martensite-austenite phase change near 60 degrees C for a co-sputter deposited film onto a Si wafer at 600 degrees C for in-situ crystallization. We used wafer stress versus temperature measurements as additional confirmation for the repeatable measurement of reversible phase transformation which completed by 80 degrees C upon heating. Up to 900 MPa completely reversible stress change was available for actuation during the thermally induced phase change. The tightest curling devices were based on a 600 nm NiTi film on 20 nm Pt and were actuated between a 200 mu m curl at 25 degrees C and flat states when heated beyond 70 degrees C. Using a 532 nm (green), 440 mW laser, we also characterized actuation times of NiTi on Pt cantilever actuators from 4 - 240 milliseconds using optical intensities ranging from 2 - 24 W/cm(2).

When the operating condition of the engine changes, the flow incidence angles may not be optimum with the blade geometry resulting in reduced off-design performance. Articulating the pitch angle of turbine blades in coordination with adjustable nozzle vanes can improve performance by maintaining flow incidence angles within the optimum range at all operating conditions of a gas turbine engine. Maintaining flow incidence angles within the optimum range can prevent the likelihood of flow separation in the blade passage and also reduce the thermal stresses developed due to aerothermal loads for variable speed gas turbine engine applications. U.S. Army Research Laboratory has partnered with University of California San Diego and Iowa State University Collaborators to conduct high fidelity stator-rotor interaction analysis for evaluating the aerodynamic efficiency benefits of articulating turbine blade concept. The flow patterns are compared between the baseline fixed geometry blades and articulating conceptual blades. The computational fluid dynamics studies were performed using a stabilized finite element method developed by the Iowa State University and University of California San Diego researchers. The results from the simulations together with viable smart material based technologies for turbine blade actuations are presented in this paper.

In contrast with typical piezo-ceramic materials, Galfenol is ductile and has an excellent ability to withstand mechanical shock. Galfenol also changes its permeability in response to applied stress. This stress-based permeability change is not time dependent and can measure static loads. The variation of magnetic induction with stress depends strongly on bias magnetic field. Typically, the performance of Galfenol is measured in a compressional load region because it has higher response there. However, in this study, we are aiming to develop a sensor for tensile stress measurement. To achieve a compression load in the sensing element, a Galfenol strip is aligned perpendicular to a tension bar, so that tension in the bar creates compression in the strip, via the Poisson effect. The experimental setup in this study consists of a polycrystalline Galfenol strip bonded in the horizontal direction of a steel dog-bone shaped tension specimen. Two permanent magnets are attached at both ends of the Galfenol strip to provide a magnetic bias field through the strip. The magnetic flux through the Galfenol strip is measured with a non-contact Hall sensor during the tensile load test. The design reported here aims at low frequency applications, such as static and dynamic tension monitoring.

GP ASME TI EQUIVALENT ELECTROMECHANICAL CIRCUIT ANALYSIS FOR ELECTRICAL TUNING OF MAGNETOSTRICTIVE UNIMORPH SYSTEM DYNAMICS SO PROCEEDINGS OF THE ASME CONFERENCE ON SMART MATERIALS, ADAPTIVE STRUCTURES AND INTELLIGENT SYSTEMS, 2016, VOL 2 SE Proceedings of the ASME Conference on Smart Materials Adaptive Structures and Intelligent Systems LA English DT Proceedings Paper CT ASME Conference on Smart Materials, Adaptive Structures and Intelligent Systems CY SEP 28-30, 2016 CL Stowe, VT SP ASME, Aerosp Div AB Equivalent electromechanical circuit analysis models provide efficient tools for analysis of power flow across multiple physical domains. In this work, we use this tool to develop a model of the power flow through mechanical, magnetic and electrical domains for analysis of magnetostrictive material based devices. The magnetostrictive unimorph system in this study consists of a magnetostrictive galfenol (Fe-Ga alloy) layer bonded to a non-magnetic flexible metal layer, a pickup coil wound around the bimetallic strip and an electrical load. Permanent magnets are used to set a magnetic bias field and to provide a tip mass load at the free end of the cantilevered unimorph. The electrical load is connected to the pickup coil, such that vibration in the magnetostrictive alloy layer caused by the vibrating structure generates electrical energy that is dissipated by the electrical load, thereby damping the vibrations in the structure. The pickup coil output voltage varies with fluctuation in the magnetic flux density due to vibration of the beam. The electrical load discussed in this paper includes an inductance and a resistor (work that also includes capacitance is ongoing). An electromechanical circuit model of the electrically loaded magnetostrictive unimorph system is used to study system dynamics. For this purpose the circuit description is simplified by a transformation of the electrical and magnetic elements into the mechanical domain. The network model of this system and simulations of its dynamic behavior are presented. C1 [Germer, M.; Marschner, U.] Tech Univ Dresden, Chair Polymer Microsyst, D-01062 Dresden, Germany. [Yoo, J.

GP ASME TI THERMAL MODEL OF A THIN FILM PULSED PYROELECTRIC GENERATOR SO PROCEEDINGS OF THE ASME SUMMER HEAT TRANSFER CONFERENCE, 2016, VOL 1 LA English DT Proceedings Paper CT ASME Summer Heat Transfer Conference CY JUL 10-14, 2016 CL Washington, DC SP ASME, Heat Transfer Div ID ENERGY CONVERTER; CONVERSION; HEAT AB Recent high energy density thin film material development has led to an increased interest in pyroelectric energy conversion. Using state-of-the-art lead-zirconate-titanate piezoelectric films capable of withstanding high electric fields we previously demonstrated single cycle energy conversion densities of 4.28 J/cm(3). While material improvement is ongoing, an equally challenging task involves developing the thermal and thermodynamic process though which we can harness this thermalptopelectric energy conversion capability. By coupling high speed thermal transients from pulsed heating with rapid charge and discharge cycles, there is potential for achieving high energy conversion efficiency. We briefly present thermodynamic equivalent models for pyroelectric power generation based on the traditional Brayton and Ericsson cycles, where temperature pressure states in a working fluid are replaced by temperature field states in a solid pyroelectric material. Net electrical work is then determined by integrating the path taken along the temperature dependent polarization curves for the material. From the thermodynamic cycles we identify the necessary cyclical thermal conditions to realize net power generation, including a figure of merit, r(EC), or the electrocaloric ratio, to aid in guiding generator design. Additionally, lumped transient analytical heat transfer models of the pyroelectric system with pulsed thermal input have been developed to evaluate the impact of reservoir temperatures, cycle frequency, and heating power on cycle output. These models are used to compare the two thermodynamic cycles. This comparison shows that as with traditional thermal cycles the Ericsson cycle provides the potential for higher cycle work while the Brayton cycle can produce a higher output power at higher thermal efficiency. Additionally, limitations to implementation of a high-speed Ericsson cycle were identified, primarily tied to conflicts between the available temperature margin and the requirement for isothermal electrical charging and discharging.

GP ASME TI NUMERICAL EVALUATION OF MULTIPLE PHASE CHANGE MATERIALS FOR PULSED ELECTRONICS APPLICATIONS SO PROCEEDINGS OF THE ASME SUMMER HEAT TRANSFER CONFERENCE, 2016, VOL 2 LA English DT Proceedings Paper CT ASME Summer Heat Transfer Conference CY JUL 10-14, 2016 CL Washington, DC SP ASME, Heat Transfer Div ID SYSTEMS AB A simple and easy to implement 1-D heat transfer modeling approach is presented in order to investigate the performance of various phase change materials (PCMs) under fast transient thermal loads. Three metallic (gallium, indium, and Bi/Pb/Sn/In alloy) and two organic (erythritol and n-octadecane) PCMs were used for comparison. A finite-difference method was used to model the transient heat transfer through the system while a heat integration or post iterative method was used to model the phase change. To improve accuracy, the material properties were adjusted at each iteration depending on the state of matter of the PCM. The model assumed that the PCM was in direct contact with the heat source, located on the top of the chip, without the presence of a thermal conductivity enhancement. Results show that the three metallic PCMs outperform organic PCMs during fast transient pulses in spite of the fact that two of the metallic PCMs (i.e. indium and Bi/Pb/Sn/In) have considerably lower volumetric heats of fusion than erythritol. This is due to the significantly higher thermal conductivity values of metals which allow faster absorption of the heat energy by the PCM, a critical need in high-energy short pulses. The most outstanding case studied in this paper, Bi/Pb/Sn/In having only 52% of erythritol's heat of fusion, showed a maximum temperature 20 degrees C lower than erythritol during a 32 J and 0.02 second pulse. This study has shown thermal buffering benefits by using a metallic PCM directly in contact with the heat source during short transient heat loads.

ULS formulations are easily reformulated as Unit-modulus Quadratic Programs (UQPs), to which Semi-Definite Relaxation (SDR) can be applied, and is often the state-of-the-art approach. SDR has the drawback of squaring the number of variables, which lifts the problem to much higher dimension and renders SDR ill-suited for large-scale ULS/UQP. In this work, we propose first-order algorithms that meet or exceed SDR performance in terms of (approximately) solving ULS problems, and also exhibit much more favorable runtime performance relative to SDR. We specialize to phase-only beamformer design, which entails additional degrees of freedom that we point out and exploit in two custom algorithms that build upon the general first-order algorithm for ULS/UQP. Simulations are used to showcase the effectiveness of the proposed algorithms. C1 [Tranter, John; Sidiropoulos, Nicholas D.; Fu, Xiao] Univ Minnesota, Dept ECE, Minneapolis, MN 55455 USA.

These 1:1 CNTs/Co3O4 and MLG/Co3O4 nano-composites were prepared by a one-step ultrasonic treatment in sodium dodecylbenzene sulfonate (SDBS) surfactant. Structure and morphology of the composites were verified using X-ray diffraction, scanning and transmission electron microscopy, and Raman spectroscopy. Magnetization (M)vs. magnetic field (H) measurements at room temperature in H up to 2.5 kOe showed that the measured M= MS at 2.5 kOe in both the CNT/Co3O4 and MLG/Co3O4 nanocomposites is enhanced by a factor of about 2.5 as compared to MS expected from the simple addition of MS measured for the two components of the nanocomposites. This is surprising since Co3O4 is a paramagnet at room temperature. These enhanced magnetic properties in the nanocomposites likely result from contributions from Co3+ ions which being in the low-spin S=0 state are non-magnetic in pristine Co3O4 but become magnetic in the reduced crystalline symmetry of the interface layers in CNTs/Co3O4 and MLG/Co3O4.

There is a trade-off among the Quality of Information (QoI) requirement and energy consumption for computation and communication. We formulate the energy-efficient data aggregation problem as a non-linear optimization problem to optimize the trade-off and control the degree of information reduction at each node subject to given QoI requirement. Using the theory of duality optimization, we prove that under a set of reasonable cost assumptions, the optimal solution can be obtained despite non-convexity of the problem. Moreover, we propose a distributed, iterative algorithm that will converge to the optimal solution. Extensive numerical results are presented to confirm the validity of the proposed solution approach. C1 [Nazemi, Sepideh; Leung, Kin K.] Imperial Coll, London, England.

In the previous study, 926 stool samples were collected from children aged 3-60 months with acute diarrhea (cases) and without diarrhea (controls) with reported 6.7% of cases and 3.2% of controls being positive for norovirus. The initial norovirus diagnostic assay was performed with real-time reverse transcription-polymerase chain reaction (real-time RT PCR) which also distinguished between genogroups I and II (GI and GII). Norovirus infection was most commonly detected in children aged 12-23 months in both cases and controls. Norovirus Genotyping Tool and phylogenetic analysis of partial sequences of the 3'. end of the RNA-dependent RNA Polymerase (RdRp) and the capsid domain region were employed to assign genotypes of the norovirus strains. GII. 4 was the most predominant capsid genotype detected at 39.5% followed by GII. 6 at 14.9%. The GII. 4 Hunter 2004 variant was the predominant strain detected. Six RdRP/capsid recombinants including GII. P7/GII.6, GII.P7/GII.14, GII.P7/GII.20, GII.P12/GII.13, GII.P17/GII.16, and GII.P21/GII.3 were also identified. This study of norovirus infection in young children in Cambodia suggests genetic diversity of norovirus as reported worldwide.

Previous efforts have shown that numerous machine learning models are vulnerable to adversarial manipulations of their inputs taking the form of adversarial samples. Such inputs are crafted by adding carefully selected perturbations to legitimate inputs so as to force the machine learning model to misbehave, for instance by outputting a wrong class if the machine learning task of interest is classification. In fact, to the best of our knowledge, all previous work on adversarial samples crafting for neural networks considered models used to solve classification tasks, most frequently in computer vision applications. In this paper, we investigate adversarial input sequences for recurrent neural networks processing sequential data. We show that the classes of algorithms introduced previously to craft adversarial samples misclassified by feed-forward neural networks can be adapted to recurrent neural networks. In a experiment, we show that adversaries can craft adversarial sequences misleading both categorical and sequential recurrent neural networks.

In this model, routing is formulated in a distributed setting where each node operating with local information only finds the next-hop node, among all social and mobile ad hoc network (MANET) communication link neighbors, whose normalized delay is the smallest. This approach minimizes the end-to-end delay and readily extends to optimize other metrics, e.g., success probability. Delay performance is analytically evaluated as a function of distance to the destination node, which is estimated in social-cognitive learning under two social-cognitive features, frequency of encounters and social pressure metric. Different mobility models (random waypoint and group) are considered for the communication topology and different graph models (uniform random or scale-free) are considered for the underlying social network. Analysis is provided for both infinite and finite node models with different levels of granularity. In addition, real social network data is used to evaluate the analysis. Results show that online learning can closely track the actual distances to the destination and the expected delay with learning is close to that with perfect knowledge of network dynamics, while it saturates with hop distance, implying that the small-world phenomenon is captured.

This paper analyzes and compares the performance of two new antenna array designs including a 4x8 right hand circularly polarized long slot antenna array and a 4x8 dual fed stacked patch antenna array, over the 4-6 GHz and 4.5-5 GHz band, respectively. The radiation characteristics were compared in terms of bandwidth, beamwidth, gain and axial ratio. Both antenna arrays have favorable axial ratio (< 1.8 dB) over their bands with average measured gain of 17 dB and 18 dB. The arrays were combined with a recently developed compact Butler matrix, and measured beam directions were all in well agreement with simulation results.

Various Location-Privacy Preserving Mechanisms (LPPMs) exist to reduce the probability of success of inference attacks on location data. However, such mechanisms have been shown to be less effective when the adversary is informed of the protection mechanism adopted, also known as white-box attacks. We propose a novel approach that makes use of targeted agility maneuvers as a more robust defense against white-box attacks. Agility maneuvers are systematically activated in response to specific system events to rapidly and continuously control the rate of change in system configurations and increase diversity in the space of readings, which would decrease the probability of success of inference attacks by an adversary. Experimental results, performed on a real data set, show that the adoption of agility maneuvers reduces the probability of success of white-box attacks to 2.68% on average, compared to 56.92% when using state-of-the-art LPPMs. C1 [Petracca, Giuseppe; Jaeger, Trent] Penn State Univ, Comp Sci & Engn, University Pk, PA 16802 USA.

Moreover, an advanced attacker may choose to approach insiders within the organization. Insider information can not only reduce the attack cost significantly but also make the attack more covert. Although stealthy attacks and insider threats have been considered separately in previous works, the coupling of the two is not well understood. As both types of threats are incentive driven, game theory is an appropriate tool to reason about the strategic behavior for each participant. We propose a non-zero sum three-player game model to study the interplay between APT and insider threats. Our model is built upon the two-player FlipIt game model for stealthy takeover with two extensions. First, we consider an asymmetric feedback structure where the defender is observable, while the attacker is stealthy and obtains delayed feedback about the defender's security updates. Second, we consider a three-player setting by introducing an insider with a double role, where it can help either the attacker or the defender according to the payoffs. We characterize the subgame perfect equilibria of a sequential game with the defender as the leader, and the insider and the attacker as the followers. We derive various insights from the game model, and discuss approaches for achieving more efficient defense in the face of both a stealthy attacker and an insider with double roles.

Stealthy malware can spread through a network undetected by utilizing zero-day exploits to propagate and hiding malicious behavior in normal activity, potentially doing significant damage before exploited vulnerabilities can be identified or patches developed. In this work, we consider a scenario in which an attacker deploys propagating malware enabling the exfiltration of data from infected devices, and a defender deploys detection and recovery mechanisms designed to control malware spread while obeying network-wide resource constraints. We use a stochastic model to represent changes in the state of the network and analytically derive an upper bound on the total rate at which an optimal attacker can exfiltrate data from the network, expressed in terms of several network parameters, when the detection rate is proportional to the outgoing data rate at each infected device. Our results can help inform cybersecurity decision-makers in judiciously allocating resources to manage risk.

Previous work is expanded using data from both an emulated network, and the validated ns-3 simulation model. Behavioral modeling is used to break up the network and applications into individual behaviors, allowing for accurate mapping between simulators, and the emulated applications. By scaling the previous validation tests beyond the limit of the emulation network, the ns-3 model can show potential scalability, while being used to validate the new CyAMS simulator. Results demonstrate that the CyAMS simulation model is capable of matching both the emulation based experiments and the previous ns-3 validation experiment results. In addition, several tests show the potential scaling power of the CyAMS model including a test featuring similar to 1 billion virtual hosts.

The ability of malware to exploit the vulnerabilities of a wireless mobile platform is often a function of the mix of software and hardware which define its platform. In this paper, we utilize a proactive strategy which takes advantage of platform diversity metrics to defend against cyber worm attacks in tactical networks. This strategy uses dynamic K-Distance pruning to minimize the total number of shared edges between nodes with similar platforms while retaining access to mission-critical services. To achieve this we introduce a new neighborhood diversity metric and show how it can be used to limit the spread of malware in a multi-platform mobile network by reducing contact between machines with similar vulnerabilities. We test our assumptions via an agent-based simulation of epidemic malware in a synthetic tactical network. C1 [Morris-King, James R.; Cam, Hasan] US Army, Res Lab, Adelphi, MD 20783 USA.

The four datasets encompass progressively complex scenarios: 1) malware infection injection via a phishing email attachment; 2) propagating botnet injection via phishing email attachment with a Single Fast Flux algorithm for bot master identification/communication; 3) propagating botnet injection via email link using a Domain Generation Algorithm for bot master identification/communication; 4) propagating botnet injection via corruption of a legitimate internal web server with Double Fast Flux for bot master identification/communication. The full datasets along with relevant documentation is available for public download. Additional datasets containing tactical network scenarios and environments will be added to the repository in the future with the goal of enabling reproducible cyber security research that will advance the science of cyber security.

These networks are designed to support the soldier to maintain situation awareness in extreme network environments. We present initial steps to enabling the study of parameters of a multi-genre network and the impact they have on other layers as well as global mission performance metrics. The framework in this paper provides experimental results of a multi-genre network consisting of EMANE, a communications network emulation platform and ELICIT, a command and control experiment platform that represents the social network layer. With these, we explore several parameters of the framework to demonstrate the impact of one parameter on the performance of other layers of the network. As a result, we are able to gain insight into enhancing performance of such networks. We are able to see initial results in terms of the impact of parameters between network layers and on the global network performance.

Current techniques do not have the ability to discern unusual features or patterns that are not a priori known. We investigate the use of deep learning for network analysis. Over the last few years, deep learning has had unprecedented success in areas such as image classification, speech recognition, etc. However, research on the use of deep learning to network or graph analysis is limited. We present three preliminary techniques that we have developed as part of the ARL Network Science CTA program: (a) unsupervised classification using a very highly trained image recognizer, namely Caffe; (b) supervised classification using a variant of convolutional neural networks on node features such as degree and assortativity; and (c) a framework called node2vec for learning representations of nodes in a network using a mapping to natural language processing.

Army tactical vehicles are increasingly crowded with many combat and communications systems. The concept of distributed terminals has been developed to address vehicle integration problems, with the premise that SOTM systems consisting of several smaller components will present fewer integration issues. These system components are distributed around the vehicle as space and function dictate. The development of open standard architecture (OSA) for DSTs will enable flexible engineering design and integration of diverse technologies to realize these systems. Furthermore, OSA will enable competitive acquisition of system components to reduce acquisition and life-cycle costs, and will enable faster fielding of incremental and innovative solutions.

The open standardized interfaces between system components are intended to increase market competition and reduce acquisition and life-cycle costs for DST components. Furthermore, the modular architecture defined in the DST OSA will enable research and development efforts to be more efficient and lower risk by focusing on the component level. Modular component development will in turn increase the speed and frequency of system technology refresh and new deployment. Current developments in system architecture are described in this paper.

In this paper, we consider the problem of verifying and repairing the visibility-based communication network formed among a number of servicing vehicles and military units that are dispersed in an environment with obstacles. We first formulate the problem in terms of algebraic graph theory to verify its connectivity. If any disconnection occurs due to a unit going out of the visibility polygons of all the vehicles, we propose a solution to repair it by dispatching a single vehicle that is optimal in terms of visibility and relocation cost. We tested our ideas through computer simulations in several case studies based on different mobility models.

Classical approaches to multi-user communications relying on tight node synchronization and/or power control are infeasible in ad hoc infrastructure-poor scenarios. In this paper, we study multi-user coding strategies with greatly reduced synchronization requirements (compared to conventional systems such as cellular) ideally suited for mobile near-ground nodes in harsh tactical environments. We exploit quasi-synchronous (QS) direct sequence (DS) code division multiple access (CDMA) codes transmitted over multiple carriers (MC). These codes are characterized by a zero cross-correlation zone (ZCZ), a measure of the delay tolerance among transmitters over which perfect code orthogonality still holds at the receiver. Using multiple carriers extends the ZCZ in time, thereby relaxing the time synchronization requirement, but tightening the frequency synchronization requirement. We study this tradeoff in this paper. We also argue that the QS MC-DS-CDMA system will have superior performance at lower VHF because of reduced multipath, reduced frequency offset, and better penetration relative to UHF or microwave systems in dense urban environments [1]-[4]. We develop an experimental testbed based on software-defined radios (SDR) and analyze the proposed approach at the lower VHF band.

We developed and validated the Pcapreplay program, which allowed us to characterize the manifestation of SLPL. We conducted experiments using Pcapreplay and Snort to explore the impact of SLPL. We graphed and analyzed this impact against our previous theoretical work. We conducted experiments using Pcapreplay and Snort to measure the impact on network intrusion detection.

Efficient and timely threat detection requires careful examination of network packets as well as integration of observed packet level behaviors into a coherent view of the network. We focus on a method to capture the semantic properties of packet transmission at different levels of granularity, making the case for using modular ontologies as a tool to capture and integrate behaviors for threat detection. This study extends the existing work on ontologies of cyber security, embracing a holistic approach and providing a well-grounded modular representation of network behaviors. We demonstrate how beaconing behavior is represented using a vocabulary of network behavior features. Then, we show how this approach can be used to detect malware beaconing to a command-and-control server. Further implications and extensions are discussed in the context of network intrusion and cyber security. C1 [Ben-Asher, Noam] US Army, Res Lab, 2800 Powder Mill Rd, Adelphi, MD 20783 USA.

We highlight a unique partnership between the cybersecurity training and research communities with the common goal of capturing human team performance. Whether in the context of a training assessment or a research endeavor; both are two sides of the same coin. As cybersecurity training events and competitions have evolved, there is increasing interest in analyzing the performance of the defenders as well as identifying the best methods of training, assessing, and educating the cybersecurity workforce. This includes analysis of the types of training, pedagogy, and the relationship between education, training, and commercial Information Technology (IT) certifications. In this work, we present a high-level look along with some initial findings from the premiere cybersecutity training event for the Army National Guard Bureau focused on enhancing the capabilities of cyber defense teams to mitigate threats to critical national infrastructure. Our first year data collection effort was conducted in the spring of 2015 and involved multiple threads of data collection. The main realization to come from this study is that improved systems and procedures should be put in place to effectively monitor and quantify team behavior for valid analyses. As the research and training partnership matures, we hope to significantly improve the data collection and assessment of human team performance in follow-on exercises.

ACyDS provides a unique virtual network view to each host in an enterprise network. That is, a host's view of its network, including subnet topology and IP address assignments of reachable hosts and servers, does not reflect physical network configurations and is different than the view of any other host in the network. ACyDS generates network views with the desired properties dynamically; it also changes every host's network view on-the-fly. ACyDS's deception approach (i) deters reconnaissance if an intruder has compromised a host in the network, (ii) prevents collusion if multiple hosts have been compromised, and (iii) increases the likelihood and confidence of detecting the presence of intruders.

This calls for routing protocols that can quickly and efficiently route the application traffic to their destinations. This paper proposes a distance-based routing protocol, named as Smallworld, which finds efficient routes to target nodes often through a very short chain of intermediate nodes, without using any routing table like other standard routing protocols. This protocol exploits the "smallworld" phenomenon of social networks where source-destination pairs typically get connected through few intermediate friends and the individuals can collectively discover such short paths. The key idea behind this routing protocol is that for forwarding an incoming packet to the destination, a node picks the next hop from between a one-hop neighbor, from its one-hop neighborhood that is closest to the destination, and a randomly selected long-distance neighbor, i.e., from outside of its one-hop neighborhood, based on which of these two neighbors is closer to the destination. This simple but effective algorithm can meet mission performance objectives by reducing packet losses, end-to-end delays, hop-counts, connectivity drops and control overheads in many tactical scenarios of interest.

In order to cope with node mobility, constrained resources, and link unreliability, communication solutions designed for Tactical Edge Networks typically present highly configurable interfaces to be adaptable for various networking conditions. However, the extreme dynamicity and heterogeneity of tactical scenarios call for network-aware, adaptive communication systems that continuously re-tune their configuration parameters to match the ever-changing network conditions. This paper presents the Dynamic Detect and Adapt Mechanism (DDAM) of the Agile Communication Middleware, a distributed solution to perform network monitoring and communication adaptation specifically designed for Tactical Edge Networks. The present work focuses on two components of the DDAM: NetSensor, which provides efficient monitoring of the network status, and NetSupervisor, which is responsible for characterizing the network technology used to connect a pair of nodes in the network. The presented results show that our solution can accurately identify the technology used to establish links between nodes.

These graphs are used to assess risk and to determine components that, when hardened, contribute most to risk reduction. While these graphs are powerful and widely used in enterprise network systems they focus on application vulnerabilities; they currently do not incorporate weaknesses in the network backbone (e.g., routing) that could lead to traffic hijacking, spoofing, eavesdropping, and several others. In this paper, we describe our work in augmenting the MulVAL attack graph software to incorporate network layer misconfigurations. Through a case study, we show how our modular data pipeline, leveraging previous work in network layer attack impact prediction, can aid system stakeholders in identifying risk and deciding on risk reduction strategies.

The goal of tactical HPC project is to advance computational capabilities of individual Soldiers at the tactical edge by leveraging mobile HPC systems. Since tactical edge is complex, dynamic, and uncertain, significant opportunities exist for real-time computing. As an example of enabling new capabilities at the tactical edge, compute-intensive urban reconnaissance planning application is presented. With GPU accelerator augmented systems, this computationally expensive algorithm was solved at interactive speeds.

A configuration problem arising is that how we can assign the antennas to JALN High Capacity Backbone (HCB) links to maximize the link availability where each JALN aircraft has four mounting points for directional antennas? The antenna assignment problem was first formulated as a Mixed Integer Linear Programming (MILP) problem, and a greedy approach was developed [1]. The goal of this work is to develop an efficient approach based on branch-and-bound method to find an optimal solution for the antenna assignment problem. The key to the success is that the problem-specific branch strategy can significantly reduce the optimization space by removing the redundant vertices that could not appear in the optimal solutions. Also, a better formulation of the antenna assignment problem reduces the constraint space by explicitly finding all maximal cliques in the conflict graph. Thus, the proposed efficient approach constructs a sequence of subproblems that monotonically converge to an optimal solution.

Such a measurement indicates whether a system is working properly and meeting its requirements. Although security and dependability metrics are regarded as key metrics for measuring the quality of systems, they are not sufficient for measuring the quality of systems that are placed in a multi-domain environment including hardware, software, network, human factors, and physical environments. In order to embrace multidimensional aspects of the quality of a system, we introduce a trustworthiness metric framework that supports three key submetrics of trust, resilience, and agility, and propose an ontology-based framework with three corresponding sub-ontologies. We also discuss how the key metrics are related to the severity of threats and the quality of assessment tools. This work is part of the cyber defense effort conducted by the Trustworthy Systems Working Group (TSWG) under the Cyber Strategic Challenge Group (CSCG) of The Technical Cooperation Program (TTCP), which is an international cooperation organization for enhancing defense science and technology.

Additionally, applications running in Tactical Edge Networks often follow one-to-many and many-to-many communication models that require the nodes' cooperation to enable data delivery. Many studies proposed the use of peer-to-peer systems in mobile ad hoc networks to remove any dependency on centralized nodes and to cope with link disruptions and network partitioning phenomena that derive from the extreme dynamicity of Tactical Edge Networks. In this paper, we compare the performance of file sharing in mobile ad hoc networks using an implementation of the BitTorrent peer-to-peer protocol and DisService, a middleware for information dissemination specifically designed for Tactical Edge Networks. DisService supports applications with routing and peer-to-peer content delivery in mobile ad hoc networks. We ran several experiments in an emulated environment to evaluate the performance of each solution when sharing large files. The obtained results show that TEN-specific solutions such as DisService can outperform traditional peer-to-peer solutions like BitTorrent.

A corresponding set of visible spectrum imagery was also collected, to facilitate cross-spectrum (also referred to as heterogeneous) face recognition research. The database consists of imagery acquired at three distances under two experimental conditions: neutral/baseline condition, and expressions condition. Annotations (spatial coordinates of key fiducial points) are provided for all images. Cross-spectrum face recognition performance on the database is benchmarked using three techniques: partial least squares, deep perceptual mapping, and coupled neural networks.

Most approaches to this problem involve modeling the relationship between corresponding images from the visible and sensing domains. This is typically done at the patch level and/or with shallow models with the aim to prevent over-fitting. In this work, rather than modeling local patches or using a simple model, we propose to use a complex, deep model to learn the relationship between the entirety of cross-modal face images. We describe a deep convolutional neural network based method that leverages a large visible image face dataset to prevent overfitting. We present experimental results on two benchmark datasets showing its effectiveness. C1 [Reale, Christopher; Kwon, Heesung] US Army Res Lab, Adelphi, MD 20783 USA.

Today, most systems that provide network services employ a fixed software stack that typically includes an operating system, web servers, and database software. This software mix as a whole constitutes the attack surface of the host, and a vulnerability in one or more of its components is a threat to the security of the entire system. Moving target defense (MTD) aims to increase the security of a system against successful intrusion by increasing an attacker's uncertainty of the attack surface. Platform migration defense (PMD) is a form of MTD that entails changing the software stack of a system. We consider a scenario in which an attacker gathers information and then selects and launches an attack against a target system that is using PMD. We perform simulations using a multi-agent model to evaluate the effectiveness of PMD against a spectrum of attackers ranging from "script-kiddies" to state-sponsored actors. In particular, we focus on two core characteristics of PMD: (i) migration rate, the frequency at which the platform is changed, and (ii) platform diversity, the number of platform configurations available, as well as two dimensions of an attacker's capabilities: (i) reconnaissance skill, the ability to collect accurate information regarding the target system, and (ii) arsenal size, the number of usable exploits at the attacker's disposal. Our results indicate that increasing migration rate and platform diversity results in a lower rate of successful attacks, even in cases where the attacker has near-perfect information regarding the target system, but that this may come at a cost in system performance. Furthermore, although the strength of an attacker is often measured by their ability to develop or acquire a large arsenal of available exploits, reconnaissance skill may be just as important a determinant for the success of an attack as the arsenal size. Our analysis provides insight into the relationship between attacker and defender capabilities, which can help inform decision-making processes of cyber defenders and lay the grounds for effective automation of cyber maneuvers.

According to Hofstede et al. (2010), culture influences behaviour and motivation for behaviour. This phenomenon may also be connected to underlying behaviours that inadvertently lead to successful exploitation. This study was undertaken in order to determine if a statistical relationship between culture and successfully exploited government and military websites housed in victim countries. The researchers relied on the use of quantitative statistical techniques to inform and support decisions. While the researchers provide some cursory analysis on the meaning of the results, the nature of the study is quantitative, and reliant upon statistical findings. The mental software referred to by Hofstede et al. (2010) should logically extend into computer network attack behaviours. Sample (2013), Sample and Karamanian (2014), successfully inferred this relationship when examining the relationship between nationalistic, patriotic website defacements and Hofstede's cultural dimensions. In 2015 Sample & Karamanian (2015) extended the research by statistically comparing Domain Name System Security Extensions adoption and rejection rates; thereby, adding defence characteristics to the body of knowledge. However, these studies did not directly address specific attack vectors success against target countries assets. This study advances the research by examining the existence of the culture and cyber relationship along with the direct relationship between successful attacks types and target countries' culture. The preliminary findings affirm the existence of a relationship between culture, specifically masculine cultural values and defaced. mil and. gov websites. The analysed data displayed significant findings across the masculine/feminine dimension. The tests performed were quantitative and included group means comparison tests. Additionally, differences were observed between SQL-injection sites and brute force attack on IIS sites. C1 [Karamanian, Andre] Cisco, San Jose, CA 95134 USA.

Network traffic from an ICS has a much lower volume than that from a typical IT enterprise network, and the traffic is much more regular (periodic) and predictable. Most intrusion detection systems for ICSs require additional capabilities. ICS network traffic is relatively predictable and regular and anomaly-based intrusion detection methods have been shown in the literature to work reasonably well. We use anomaly-based methods as one line of defense. We propose to strengthen ICS intrusion detection methods by adding two process-oriented alerting methods. Unlike most anomaly detection methods, these two methods are not configured solely by a network engineer based on inspection of network traffic. We utilize Critical Process Variables, which are defined by the plant operators themselves. The advantage is that the plant operators have the best knowledge of the critical assets of their system. Limiting values of the Critical Process Variables are defined collaboratively by the plant operator and the network security engineer. A network sensor then alerts a Human Analyst when Critical Process Variables values exceed the defined ranges. We also introduce a third method, which employs Process Network Parameter Metrics, which are also defined collaboratively with the plant operator. Process Network Parameter Metrics are pre-defined measurements from network traffic that may indicate that either process components are missing or there is additional traffic present that the process should not normally produce. After initial discussions with the plant operator, the network security engineer designs network models and metrics with appropriate alerting functions in the network sensor. Alerts from Process Network Parameter Metrics may not indicate a critical security incident as Critical Process Variables would, but they may provide an important warning that suspicious behavior is present.

These are consistent with their other provocations such as their nuclear weapons programs and aggressive activities along the border. The damage of these attacks is increasing, and they are a significant annoyance that is preventing progress on resolving the conflict between the two states. This paper will first survey the dramatic differences between North Korea and South Korea in cyberspace, and summarize the continuing evolution of North Korean cyberattacks. Attribution of most attacks to North Korea is not difficult because many of the same methods are used repeatedly, and many of the attacks are timed to coincide with important anniversaries. Thus, unlike with cybercriminals, these cyberattacks can often be predicted and recognized, and preparations can be made for them. North Korean cyberattacks often violate international law since they indiscriminately target civilians since the state considers itself not subject to international law. Nonetheless, there are many things South Korea can do to respond. International law can be invoked even without cooperation by the parties, and sanctions can be imposed. Defenses can be strengthened by better coordination of defenses between the private and governmental sectors through a unified early-warning defense. Repeated cyberattacks also justify a counterattack according to international law. North Korea has a limited set of state-mandated software on a small set of networks, and this makes widespread effects of cyberattacks on them quite possible. The main difficulty is getting access to these networks, but there are ways, especially given the growing use of smartphones in North Korea. As for attack goals, what North Korea fears the most is information about the rest of the world getting to their citizens, so sending accurate such information should be a major goal of cyber-counterattacks -- data destruction is unnecessary.

However, a large number of well-labeled training images may not always be available. To alleviate this problem, the web resources-aided scene classification framework was proposed. The present paper is a new development based on our previously proposed framework [1], with the following improvements. First, a text-based filtering algorithm is developed to remove irrelevant web search returns since irrelevant web search returns provide irrelevant or even wrong information about the class of an image. Second, an adaptive fusion algorithm is developed for the integration of visual feature-based and web textual feature-based classification results. This adaptive fusion algorithm is inspired by the multisensory integration mechanism of human whose adaptability is achieved by reliability-dependent weighting of different sensory modalities. Experimental results show that the proposed web textual resources aided image classification framework can improve classification accuracy of some classes by 13% and 12% in the UIUC-Sports and LabelMe8 datasets, respectively.

In cooperative or hostile environments, agents communicate their subjective opinions about various phenomenon. However, sources of these opinions are not always competent and honest but often erroneous or even malicious. Furthermore, malicious sources may adopt certain behaviors to mislead the decision maker in a specific way. Fortunately, the reports of such misleading sources are correlated to ground truth. Using statistical methods, one can learn how likely a source distorts the ground truth and the associated distortion models so that reports from these sources can still be fused to enhance estimation of the ground truth. In this work, we propose to learn a number of statistically meaningful opinion transformations that represent various behaviors of information sources. Then, we exploit these transformations while fusing opinions from unreliable sources. Using real data from the Web and through extensive comparison with recent trust-based approaches over simulations, we show that our approach can be used to determine set of transformations that may lead to more accurate estimation of the truth.

Subjective networks generalize Bayesian networks from being based on probability calculus, to being based on subjective logic. In addition, subjective networks generalise Bayesian networks from assuming a global view of input arguments by a single analyst, to taking subjective view of input arguments by multiple agents who might have conflicting opinions. The result is a highly flexible and expressive framework for modelling and analysing realistic situations, which is also backwards compatible with traditional Bayesian networks.

This paper develops subjective belief propagation (SBP) that extends regular belief propagation (BP) to efficiently infer uncertain marginal probabilities in subjective Bayesian networks. It is shown that SBP's runtime exhibits only slightly slower performance than standard BP but is able to effectively characterize a distribution for the marginals. Simulations affirm that unlike the valuation-based system, a previous uncertain probabilistic reasoning framework, SBP is able to effectively capture bounds for the actual error in a consistent manner.

The information on the joint distribution of the sources available at the two sides is asymmetric, in that one user knows the true distribution, whereas the other user observes a different distribution. This paper considers the minimum worst-case zero-error codeword length under such asymmetric prior distributions. We investigate the cases for which reconciling the information mismatch is better or worse than not reconciling it, but instead using an encoding scheme that ensures zero-error with possibly increased communication rate. Our results indicate a reconciliation-communication tradeoff and that there exist cases for which partially reconciling the mismatched information is better than both perfect reconciliation and no reconciliation.

Body heat in a MWD increases due to work, and the primary means for reducing this heat are resting and panting. Body-worn sensors can enable monitoring of work level and respiratory rate in real time. They can thereby provide real-time objective indicators of thermal strain in MWDs. In this paper a system is proposed for using collar-worn accelerometer, global positioning system (GPS), and audio recorder sensors to provide real-time estimates of work level and respiration (breathing and panting) rate. Automated methods are demonstrated for using a collar-worn accelerometer and GPS sensor to estimate work levels during multiple short-duration activities, and for estimating respiration rates from a collar worn audio recorder. The potential utility of these estimates for forecasting and monitoring thermal strain is assessed based on performance in out of sample prediction of core temperature (Tc) statistics, which are obtained from ingestible sensors. Using cross-validation, regression models are trained from accelerometer- and GPS-based activity estimates to predict rate of change in Tc, obtaining a correlation of r=0.59 between actual and predicted Tc change rates. Regression models are also trained from audio-based respiration rate estimates during recovery to predict the Tc values immediately prior to recovery, obtaining a correlation of r=0.49 between actual and predicted Tc.

The X-band element is a combination of a concentric annular ring slot shorted on the outer edge and a narrowband patch. All elements achieve circular polarization by truncating opposing corners of the rings. Both bands utilize two orthogonal feeds to allow either right hand or left hand circular polarization.

Virtually all current approaches estimate the DoA based on the phase of the impinging signal on a sensor array. This approach has several challenges: for example, it requires tight synchronization amongst array elements, and the estimated DoA is very sensitive to the specification of the array geometry. We propose a Bayesian DoA estimation procedure based on the received signal strength (RSS) gradient. RSS is readily computed by most sensors, and the RSS gradient points towards the source when the received signal's dominant component is the direct path. Though non-uniform shadowing, small-scale fading, and multipath generally corrupt the accuracy of the RSS gradient as a DoA estimate, these effects are significantly less at lower VHF. We show through simulations and applications to actual datasets that our approach provides a simple and accurate method to estimate DoA and its associated uncertainty, even in cluttered environments.

The formulation of interest here is from the volumetric current integration method, combined with a ray-based approach for the treatment of ground effects. Through comparisons with a reference solution provided by a full-wave solver, the region of validity of the closed-form approximate solution as a function of trunk length, trunk radius, incidence angle, and polarization is derived. Trunks with and without tapering along their lengths are considered. It is noted that in general the error behavior of the vv solution exhibits more complexity compared to that of the hh solution, due to the Brewster angle effects of the trunk and the ground; consequently, the hh solution is valid over a wider range of length and radius values. The backscattering signatures of the trunks are also examined in the imaging domain. It is found that the analytical solution can correctly predict the single ground-bounce returns but may not consistently capture other less prominent effects such as scattering from the top of the trunk and higher-order interactions.

This work is in the context of humanitarian-assistance, disaster-relief missions where an operator tasks the robot from large standoff distances through extreme, real-world environments and robust operations are required to ensure optimized information gathering. Our proposed approach, referred to as the informed recovery behavior, identities and selects from candidate regions by modeling both navigation and communication costs using experience-based samples. Finally, we experimentally validate the feasibility of our method and demonstrate an improvement in reducing the time required to navigate and transmit data to an operator, compared to a realistic, baseline approach, through a series of trials in an uncontrolled, real-world environment.

In this work we create a novel ground and aerial autonomous robotic system to surveil a human-robot team's surroundings for targets of interest, which could be e.g., disaster victims, infrastructure inspection, data to support research or public safety, or threats to the human team members' safety. To represent this general case, our system identifies threats to human safety by surveilling the team's surroundings, identifying threats, and notifying the human team member. We provide an interface that visualizes threat targets and allows the human operator to create and modify the surveillance plan. We note that this 31) surveillance task resembles the Art Gallery Problem (AGP) with a time-sensitive route planning aspect similar to the Traveling Salesman Problem (TSP), both of which are NP-hard. We incorporate a human operator into the decision making process of a surveillance system to address the viewpoint selection and route minimization problems, and to extract semantic information from the scene to increase search effectiveness. We construct a system for this collaborative, human-robot team surveillance task using a low-cost Unmanned Aerial Vehicle (UAV) and a more-capable Unmanned Ground Vehicle (UGV). We evaluate the resulting system with a large experiment set (120 trials) conducted in a real-world, 31), cluttered, urban setting and examine the difference a scenario specific plan makes to the detection of threat targets compared to a baseline algorithmically-generated plan.

In practice, most results have focused on protocol design, showing that by restricting the complexity of protocols it is possible to design parsers with desirable and formally verifiable properties, such as correctness and equivalence. When we consider existing protocols, however, many of these were not subjected to formal analysis during their design, and many are not implemented in a manner consistent with their formal documentation. Determining a grammar for such protocols is the first step in analyzing them, which places this problem in the domain of grammatical inference, for which a deep theoretical literature exists. In particular, although it has been shown that the higher level categories of the Chomsky hierarchy cannot be generically learned, it is also known that certain subcategories of that hierarchy can be effectively learned. In this paper, we summarize some theoretical results for inferring wellknown Chomsky grammars, with special attention to contextfree grammars (CFGs) and their generated languages (CFLs). We then demonstrate that, despite negative learnability results in the theoretical regime, we can use long short-term memory (LSTM) networks, a type of recurrent neural network (RNN) architecture, to learn a grammar for URIs that appear in Apache HTTP access logs for a particular server with high accuracy. We discuss these results in the context of grammatical inference, and suggest avenues for further research into learnability of a subgroup of the context-free grammars.

The nanoparticles were doped into the silica soot of preforms, which were drawn into fibers. The Er luminescence lifetimes of the NP-doped cores are longer than those of corresponding solution-doped silica, and substantially less Al is incorporated into the NP-doped cores. Optical-to-optical slope efficiencies of greater than 71% have been measured. Initial investigations of stimulated Brillouin scattering (SBS) have indicated that SBS suppression is achieved by NP doping, where we observed a low intrinsic Brillouin gain coefficient, of similar to 1x 10(-11) m/W and the Brillouin bandwidth was increased by 2.5x compared to fused silica.

It is passively Q-switched via a Cr4+:YAG saturable absorber and generates 2.4W at 1030nm in a 110 mu J pulse train. Lithium triborate (LBO) and beta-barium borate (BBO) are used to achieve 325mW average power at the fourth harmonic.

Similar to the conventional Ultraviolet (UV)-Visible ( Vis) LIBS, a broad band emission spectrum of condensed phase samples covering the entire 5.6 to 10 mu m region can be acquired from just a single laser-induced micro-plasma or averaging a few single laser-induced micro-plasmas. This setup has enabled probing samples "as is" without the need for extensive sample preparation and also offers the possibility of a simultaneous UV-Vis and LWIR LIBS measurement. A Martian regolith simulant (JSC Mars-1A) was studied with this novel Vis + LWIR LIBS array system. A broad SiO2 vibrational emission feature around 9.5 mu m and multiple strong emission features between 6.5 to 8 mu m can be clearly identified. The 6.5 to 8 mu m features are possibly from biological impurities of the simulant. JSC Mars-1A samples with organic methyl salicylate (MeS, wintergreen oil) and Dimethyl methyl-phosphonate ( DMMP) residues were also probed using the LWIR LIBS array system. Both molecular spectral signature around 6.5 mu m and 9.5 mu m of Martian regolith simulant and MeS and DMMP molecular signature emissions, such as Aromatic CC stretching band at 7.5 mu m, C-CH3O asymmetric deformation at 7.6 mu m, and P=O stretching band at 7.9 mu m, are clearly observed from the LIBS emission spectra in the LWIR region.

In the current world environment of rapidly changing and progressing technologies, adaptability is the lynchpin for success. Tunable sources, such as Quantum Cascade Lasers (QCLs), are becoming more common to address the adaptability need on the proactive side. It follows that sensors themselves must then be able to expand and adapt to aid in this endeavor. The research outlined in this paper further explores the relationship between the frame rate of a sensor and the modulation frequency of an incoming signal. Signals modulated at frequencies matching or near the frame rate of a sensor cause aliasing effects more consistently and frequently than those further from the sensor's frame rate. These situations affect the sensor's accuracy in these regions, creating a "blind spot" for the sensor where fluctuations in the signal are indistinguishable from frame to frame. The relationship between the frame rate of a sensor and the modulation frequency of a signal, quantified by a change in irradiance from frame to frame, was previously explored. From these primary findings, an algorithm was developed utilizing a method analogous to that of on-off keying, to improve frame rate adaptability. This algorithm was tested and expanded to include more complex scenarios. The potential for this method, including further testing, project scope and direction, as well as future complexities involving the inclusion of a feedback loop to the laser modulation controller are presented. The paper concludes with discussions on applications of these results to improve current and future sensor technology development, testing, and characterization.

The agent's true intentions, which may be adversarial or helpful, is unknown to the communicating parties. Actions taken by the agent are governed by its intentions, and they may improve or deteriorate the communication performance. We characterize the optimal transmission policies to minimize the end-to-end average semantic error, i.e., difference between the meanings of intended and recovered messages, under the uncertainty in the agent's true intentions. We formulate the semantic communication problem as a Bayesian game, and investigate the conditions under which a pure strategy Bayesian Nash equilibrium exists. We then explore the structure of the encoding and decoding functions under the mixed strategy Bayesian Nash equilibrium, which for the semantic communication problem at hand always exists. Our results show that the optimal policies are strongly influenced by the belief the parties hold about the agent's true intention.

In such settings, mobile nodes use Delay Tolerant Network (DTN) protocols for exchanging location specific data. High transmission delay, packet loss and intermittent connectivity increases the need for efficient data transmission in such scenarios. In this paper, we evaluate network coding for efficient data exchange between mobile wireless nodes under the presence of an intermittent backhaul network, like a satellite or cellular link. We analyze the upper bound of savings achievable with network coding for single-hop packet transmission, and introduce a network coding algorithm focused on reducing the required number of packet transmissions in such a setting. Evaluation of our proposed data exchange protocol shows how network coding can be applied to reduce transmission delay and minimize the dependency on an intermittent backhaul network in a communication scenario typical of a military environment.

Although the complete structure of a D2D-MSN plays a key role in understanding its performance, such knowledge is not readily available due to the difficulty of collecting connectivity information from the vast amount of users. To model the structure, we define a D2D-MSN network that jointly captures the social connectivity over the MSN and the opportunistic D2D contacts among users. A random walk with self loop (RWSL) scheme that quickly converges to its stationary distribution is proposed to collect a subset of D2D-MSN nodes. An estimator is then introduced to obtain an unbiased estimate of the D2D-MSN graph's joint degree distribution, p(ij), from-the set of visited nodes, leading to an unbiased RWSL scheme. The resulting estimate of p(ij) can be used as a statistic for creating synthetic graph and generating functions for analyzing robustness of D2D-MSN. Numerical results show that the proposed unbiased RWSL converges faster to its stationary distribution, achieves higher joint degree distribution accuracy, and visits less number of nodes, compared to existing graph exploration schemes.

The growing involvement of individuals create the situation that colliding, even contradicting information coexist and propagate in the same network, which gives rise to an interesting question: how will the conflicting information propagate? To answer this question, the propagation process is described to be an Susceptible-Infected-Cured (SIC) epidemic, and we propose an inference algorithm to study the transient behavior of the competing propagation processes in connected networks. Moreover, we provide an analytic method to derive the conditional infection count distribution for networks with special topologies, as a step further to understand the evolution. A trace collected from the Internet is analyzed to validate our model and methods. C1 [Wang, Jie; Wang, Wenye] North Carolina State Univ, Dept Elect & Comp Engn, Raleigh, NC 27606 USA.

In this problem, a player wishes to successively refine an estimate of the value of a continuous random variable by posing binary queries and receiving noisy responses. When the queries are designed non-adaptively as a single block and the noisy responses are modeled as the output of a binary symmetrie channel the 20 questions problem can be mapped to an equivalent problem of channel coding with unequal error protection (UEP). A superposition coding strategy with UEP is introduced that has error exponent that is significantly better than that of the UEP repetition code introduced by Variani et al. [1].

It is shown that if the minimum image cardinality of a source set over a DMC has a specific entropy characterization, then the image of this source set will be information stable. In many applications, this requirement on the source set can be satisfied using the method of equal-image-size source partitioning. A construction of a strong secrecy subcode from a weak secrecy code for the wiretap channel is provided as an example to illustrate the use of the information stabilization technique.

The proliferation of improvised explosive devices of all types in the Iraqi and Afghan theaters has demonstrated that inexpensive, commercial off-the-shelf technology and some electronics knowledge can be combined to significantly impact high-tech operations. Autonomous GPS-guided and semi-autonomous unmanned aerial vehicles will change the paradigm in their employment in the very near future. While a single attack might be insignificant, a swarm of robotic devices could prove a credible threat. In this paper we discuss the impact and limitations of commercially off-the-shelf drones and what measures might be used to counter these devices. We back up our findings with flight tests and observations on systems commonly used for research but also easily available to adversaries and bad actors. Finally, we present some speculation on the potential implementation of swarms using these vehicles as a continuation to the discussion.

A genetic algorithm is combined with space partitioning methods to find an optimized path to ensure complete coverage of a desired area with necessary overlap for generating a 3D map. This path provides for the collection of detailed information of man-made structures within the area and also consider areas of avoidance and adjust for problematic terrain (such as tall vegetation). The result is a flight path for a multirotor that includes waypoint, altitude, heading, and camera angle for all points along the flight path.

Existing off-the-shelf radios at this band are bulky, usually operate at high power levels (a few watts), and require relatively large antennas to enable long range communications. To remedy these shortcomings, we develop a small-form-factor low-VHF radio that leverages the ZigBee technology with a frequency conversion technique. A bi-directional frequency converter for the radio is designed to translate ZigBee signals into low-VHF carriers and optimized to minimize power consumption, and simultaneously maximize system gain and sensitivity. This radio also comes with a newly developed miniaturized antenna [1] (<= 0.02 lambda(0) in height and lateral dimensions at 40 MHz) having much higher efficiency compared to antennas of similar sizes. This antenna allows the compact radio system to operate at lower power and on small robotic platforms needed for military or rescue missions.

Key to antenna miniaturization is to reduce the overall size of the antenna as well as the height of the radiating dipoles above its ground plane. In the following paper, we examine the height reduction and antenna performance using a magneto-dielectric material consisting of Nickel Zinc Ferrite nano particles. Through simulation and measurements, we demonstrate that a standard UHF SATCOM antenna requiring a 9.5" separation from its radiating element to ground plane will exhibit equal to or better performance when placed 4.5" above a magneto-dielectric ground plane - a reduction of approximately 50%.

This ongoing research project, conducted off the coast of Duck, NC, during October-November of 2015, provided an opportunity to measure EM propagation during the CASPER at-sea experimental campaigns. The measured signal is used to invert for the evaporation duct refractivity profile based on Terrain Parabolic Equation Model (TPEM) and compared to the profile predicted from NAVSLaM using concurrent meteorological and oceanographic measurements as input.

To such networks, when a query reaches an expert who does not have sufficient expertise, this query needs to be routed to other experts for further processing until it is completely solved; therefore, query answering efficiency is sensitive to the underlying query routing mechanism being used. Among all possible query routing mechanisms, decentralized search, operating purely on each expert's local information without any knowledge of network global structure, represents the most basic and scalable routing mechanism. however, there is still a lack of fundamental understanding of the efficiency of decentralized search in expert networks. Tu this regard, we investigate decentralized search by quantifying its performance under a variety of network settings. Our key findings reveal the existence of network conditions, under which decentralized search can achieve significantly short query routing paths (i.e., between O(log n) and O(log(2) n) hops, n: total number of experts in the network). Based on Stiehl theoretical foundation, we then study how the unique properties of decentralized search in expert networks is related to the anecdotal small-world phenomenon. To the best of our knowledge, this is the first work studying fundamental behaviors of decentralized search in expert networks. The developed performance bounds, confirmed by real datasets, can assist in predicting network performance and designing complex expert networks.

In particular, we take the network approach to understanding the teams and consider optimizing the teams with several operations (e.g., replacement, expansion, shrinkage). We develop TEAMOPT, a system to assist users in optimizing the team performance interactively to support the changes to a team. TEAMOPT takes as input a large network of individuals (e.g., co-author network of researchers) and is able to assist users in assembling a team with specific requirements and optimizing the team in response to the changes made to the team. It is effective in finding the best candidates, and interactive with users' feedback in the loop. The system is developed using HTML5, JavaScript, D3.js (front-end) and Python CGI (back-end). A prototype system is already deployed. We will invite the audience to experiment with our TEAMOPT in terms of its effectiveness, efficiency and applicability to various scenarios.

These tests were developed between 1929 and 1932 to quantify a fuel's anti-knock performance in spark-ignition engines. Since knock imposes limits on the maximum engine compression ratio, which correlates to engine performance, the anti-knock property of a fuel is a crucial design constraint. Prior to the development of the octane number tests, engines were designed to run at very low compression ratios to avoid knock, significantly limiting their performance. The octane number tests created standards that allowed for better engine development and advancements in fuel technology. Engines could now be designed to handle a specific octane number of fuel allowing for increased performance. The demand for better performing engines resulted in an increase in the average fuel octane number from 50 to 75 during this period, with the Great Depression and World War II setting the stage for this advancement. These advancements in fuel technology played a crucial role in the survival of the American automobile industry during the Great Depression, the Allied success in World War II, in addition to creating the 'American obsession' with powerful automobiles. This paper provides an overview of knock, a historical summary on the development of the octane number tests, the corresponding advancements in fuel technology, and the implications of these advancements on American society.

The newest education institution in the U.S. Army was created to unify the training and educational institutions of the Army, making the large learning organization more effective and efficient for its soldiers, bringing together 37 different institutions in 23 states, with an annual student throughput of 500,000. Encompassing two different degree-producing schools, the university seeks to improve opportunities for soldiers in credentialing and licensure, along with exploring the ability to grant a limited number of military-focused undergraduate degrees. Just as critical, the university has the responsibility to grow relationships with civilian learning partners in the educational and corporate communities to aid active Army, National Guard, and Army Reserve soldiers while in service and in thousands of cities and towns throughout the United States.

These devices are well suited for high voltage, high temperature pulsed power and continuous power electronic systems. A pulse-forming network (PFN) circuit and a low inductance, series resistor-capacitor (LRC) circuit were developed to evaluate both the fast dI/dt capability and the pulse safe operating area (SOA) of the SiC SGTO. Transient simulations of the high voltage SiC SGTOs were also performed on a narrow pulse LRC circuit to investigate the device's switching behavior under extreme pulsed conditions.

There is lack of material models that capture the mechanical deformation under transient dynamic loads at elevated temperatures. Electronics in downhole drilling, automotive and aerospace applications may often be exposed to high temperature during storage, operation and handling in addition to high strain rate transient dynamic loads. Strain rates in the neighborhood of 1-100 per sec may be encountered during operation. Anand Viscoplasiticity models which have been widely used for modeling of material behavior of solder alloys require nine-constants to describe material constitutive behavior. Prior published data on Anand Constants for SAC leadfree solder alloys is limited to either low strain rates or lower temperatures in the neighborhood of 125 degrees C. In this study, mechanical properties of lead free SAC105 has been measured for strain rates 1-100 per sec at elevated temperatures higher than 125 degrees C. Stress-Strain curves have been plotted over a wide range of strain rates and temperatures for pristine specimen which have been fabricated using reflow profiles representative of solder-joint production assemblies. The fabricated SAC105 leadfree alloys specimen have been tested at strain rates of 10, 35, 50 and 75 per sec at various operating temperatures including 150 degrees C, 175 degrees C, and 200 degrees C. Experimental data for the specimen has been fit to the Anand's viscoplastic model. Furthermore, the Anand Model has been used to model the uniaxial tensile test and predict the stress-strain behavior of the solder alloys at elevated temperature. The comparison of the model predictions with the experimental data indicates that the model constants capture the non-linear material behavior for the SAC105 solder alloy accurately.

A type-1 fuzzy assessor is used to transform crisp performance attribute inputs into a meta-architecture assessment for use as part of the fitness function of a genetic algorithm. This algorithm is applied to the generation, assessment, and selection of a meta-architecture for a hypothetical lethal, non-line of sight fires SoS for which the key performance attributes are affordability, flexibility, performance, robustness, and reliability. Combinations of existing systems that have nonlinear interactions are assessed and compared to the United States Military Future Combat System.

DDFM is the application and integration of appropriate processes, technologies, and knowledge based capabilities to improve the reliability and maintenance effectiveness of Army Aircraft Systems and components. Uses a systems engineering approach to collect data, enable analysis, and support the decision-making processes system acquisition, sustainment, and operations. As part of an effort to mitigate rising costs, the Department of Defense has invested in the development of Digital Source Collectors as an onboard aircraft data recording system used to collect data. As a result, Army Aviation has installed thousands of DSCs. As part of its DDFM initiative, DSCs support actionable information and has enabled Army Aviation's airworthiness authority to remediate certain time-based maintenance practices. This enables substantial cost avoidance, eases the Warfighter's maintenance burden, and thereby promotes greater fleetwide emphasis on the performance of higher overall quality maintenance. Army Aviation does this to support mission readiness. Algorithms provide vibration based diagnostics capability, enabling rotor track and balance, or rotor smoothing, to reduce rotor vibrations. Rotor smoothing minimizes loads on life-limited dynamic components in the rotor system. It improves aircrew human factors, reduces vibration in non-rotor system components, and supports the reduction of vibration induced failures. The algorithms automate condition monitoring, reducing time-based visual inspection requirements and component replacements that can result from human error within austere environments under the extreme pressures of combat. Data analysis shows that the technology supports fleetwide mitigation of cost and maintenance burden; where sustainment constitutes up to 70% of ownership costs. Time extensions enabled through proper DSC utilization result in significant cost avoidance benefits. This increases time on and wing, thereby reducing the frequency and magnitude of costly component replacement. The Army Aviation and Missile Command Logistics Center produced the Post Implementation Assessment methodology featured in this paper as a repeatable procedure to measure, capture, and communicate how DDFM supports efficiency.

Little research, however, has been directed toward understanding how stress influences subjective SA, an individual's assumption of their objective SA accuracy. The present experiment uses newly developed methods for highly controlled manipulations of stress, and newly designed measurements of risk-taking in a complex combat simulation. Results of this research indicated that high levels of acute stress may lead individuals to be overconfident in their SA and take more risks. Results are discussed in terms of their importance for individuals who require adequate SA in order to perform occupational tasks effectively, such as air-traffic controllers, pilots, and military personnel.

One of the popular social engineering attacks is a phishing attack, exploiting humans' vulnerability in order to obtain individuals' private or credential information. Recent studies have found that the so called phishing susceptibility' (i.e., the likelihood of being phished) is closely correlated with the individuals' personality traits. In particular, the relations between phishing susceptibility and Big Five personality traits have been analyzed via empirical studies in diverse domains. However, little prior work has proposed a mathematical model investigating the effect of an individual's personality traits on perceived trust or risk and decision performance. This work proposes a probability model using Stochastic Petri Nets in order to examine the effect of an individual human's personality traits on perceived trust and risk, and decision performance. Our results show that agreeableness and neuroticism have significant effect on perceived trust and risk, and decision performance particularly when openness and conscientiousness is very low. The developed mathematical model can be applied to predict what personality profiles in an organization are more exposed to social engineering, suggesting customized security training scenarios.

Volunteers played a negotiation game in which an embodied, digital virtual agent both displayed an angry, happy, or neutral facial expression and played either cooperatively or competitively. Results indicated that users who negotiated with the angry virtual agent performed significantly worse on the Mind in the Eye Task compared to those who interacted with the happy virtual agent. The results indicate that exposure to an angry virtual agent decreased humans' ability to take the mental perspective of another person. These results offer speculations about how negative affect associated with virtual agents can have detrimental implications for human-agent interactions that requires theory of mind type situational awareness, especially regarding virtual agent technology for rehabilitating theory of mind deficits (e.g., for individuals on the Autism spectrum).

Degraded SA is one reason that human users make poor interaction decisions that cause joint system performance to suffer. One key reason for degraded SA is the hierarchical design where the human user is at the apex of the command hierarchy. Within this structure the human user is not able to be fully integrated into the system, which can lead to 'out of the loop' performance issues. We propose that SA could be measured in real time by leveraging psychophysiological methods often used in cognitive neuroscience research. We then discuss a potential framework that could not only identify degraded SA in real time, but could mitigate these degradations. Such a framework would be successful because it would genuinely integrate the human user into the system, essentially closing the loop that underlies joint system failures.

Controlled Natural Languages (languages built from a subset of natural language, which are both computer-and human-readable) hold promise for Human Computer Collaboration via these platforms, especially when the human user needs to add information to a knowledgebase or make queries, as they provide a transparent, shared representation. Controlled Natural Languages, however, are typically not optimized for human use and understanding. This paper presents the development and implementation of a framework to test the relative ease of comprehension of different Controlled Natural Language statements. The experiments presented in this paper show an advantage for one particular Controlled Natural Language statement over another, but only when responses are made under strict time pressure. These types of experiments allow researchers to make recommendations on how to improve the use and design of a Controlled Natural Language for more robust comprehension, particularly in tactical environments.

As such, the role of someone onboard the vehicle will change from the active role of a driver to the passive role of a passenger. The goal of this work is to provide an initial assessment of this interaction, with a specific focus on the impact of different available control interfaces on trust, usability, and performance. Participants interacted with two simulated driverless passenger vehicles that were designed to mirror a real-world prototype vehicle for Soldier transit on a U.S. military installation. Vehicle 1 had a traditional wheel and pedal control interface, as well as two buttons to disengage or reengage the vehicle's automation system. Vehicle 2 only had the button system available with which to disengage the automation and bring the vehicle to a safe stop in the simulation and then reengage. Both vehicles were designed to function optimally throughout the virtual environment. Findings suggested equal trust and usability ratings between the two vehicles. However, participants tended to intervene more often with the traditional control interface. Individual differences and preference ratings are reported.

A simple yet robust method for sizing of the renewable generators is developed. Two operation schemes are investigated. A case study at a farm in California suggests that, by using renewable energy, the hybrid system can save over $600K for the farm over 20 years. Furthermore, non-critical farm loads, such as water pumping system, can be operated flexibly to achieve greater saving of energy. In addition, the farm power supply can be maintained in part or in full by islanding the farm. C1 [Giourdjian, Arthur] San Diego Gas & Elect, San Diego, CA USA.

Despite their tremendous success in various image processing tasks, synthesis-based and analysis-based sparse models fall short in classification tasks. It was hypothesized that this is partly due to the linear dependence of the dictionary atoms. In this work, we aim at improving classification performances by compensating for such dependence. The proposed methodology consists in grouping the atoms of the dictionary using clustering methods. This allows to sparsely model images from various scene classes and use such a model for classification. Experimental evidence shows the benefit of such an approach. Finally, we propose a supervised way to train the baseline representation for each class-specific dictionary, and achieve multiple classification by finding the minimum distance between the learned baseline representation and the data's sub-dictionary representation. Experiments seem to indicate that such approach achieves scene-classification performances that are comparable to the state of the art.

The team carried out a technical review into the current status of theoretical and practical developments of methods, tools and techniques supporting joint exploitation of multimedia data sources. In particular, content-based information retrieval and analytics was considered as a means to allow military experts to exploit multiple data sources in a rapid fashion for sensemaking and knowledge generation. Elements included contextual understanding of complex events through computational/human processing techniques, event prediction through the automated extraction of network features, temporal trends, hidden clusters and resource flows, and the use of machine processing for automated translation, parsing, information extraction, and summarization of unstructured and semistructured data. The main conclusions of the study are that important research gaps exist in all the technical areas covered in this report. Though the research areas and developments are being advanced in the military sector and the civil sector, in particular, they remain at low levels of technical maturity for defense and security system applications. It is recommended that NATO collaborative research effort be expanded to advance those approaches that are most pertinent to our overall aim of enhancing the contextual understanding of complex events through CBA of heterogeneous multimedia streams.

An immediate research question is whether contemporary IoT concepts can be applied also to military battlefield environments and can realize benefits similar to those in industry. Military environments, especially those that depend on tactical communications, are much more challenging than commercial environments. Thus it is likely many commercial IoT architectures and technologies may not translate into the military domain and others will require additional research to enable deployment and efficient implementation. This paper investigates these issues and describes potential military operational activities that could benefit from commercial IoT technologies, including logistics, sensing/surveillance, and situation awareness. In addition, the paper lays out a roadmap for future research necessary to leverage IoT and apply it to the tactical battlefield environment.

Powering systems at a distance using lasers to either recharge batteries or run devices offers significant advantages. Using remote lasers can untether the user, unburden the individual from transporting extra batteries, as well as eliminate the down time associated with recall of critical assets for related battery swap-out and charging. In this paper, we focus on selecting a wavelength and power level that can be implemented with relative safety margins for transmission of electrical power at distances for energizing unmanned systems. We shall also discuss the planning, laser selection and testing, laser hazard analysis and the detector selection for a laser based power transfer system.
