AB Neuroimaging technology has previously confined research to the laboratory setting, an environment that limits the generalizability of results to the real world. With the recent advent of high-density, wireless EEG technology, the promise of truly naturalistic neuroimaging research is closer than ever. This project presents a multi-aspect wearable neuroimaging system designed for use in daily life and tailored for studying stress. This system addresses several obstacles to collecting highly informative real-world neuroimaging data. First, neurophysiological data collected in a natural setting produces a rich dataset that is difficult to interpret without extensive contextual information. Our system provides this information from both user input and continuously collected physiological and actigraphy data. Second, the approach must minimally interfere with the user's life in order to avoid altering natural behavior. Our fully wearable, light-weight design integrates multiple components to maximize user comfort, while burden on the user is minimized by the use of a typical Android-based cell phone for occasional, brief interaction and also as the sole integration center for the system. While this system is optimized for the study of stress, the advances of this approach could be applied to study other naturally occurring psychological phenomena.

AB Background: The BIG score (Admission base deficit (B), International normalized ratio (I), and Glasgow Coma Scale (G)) has been shown to predict mortality on admission in pediatric trauma patients. The objective of this study was to assess its performance in predicting mortality in an adult trauma population, and to compare it with the existing Trauma and Injury Severity Score (TRISS) and probability of survival (PS09) score.
Materials and methods: A retrospective analysis using data collected between 2005 and 2010 from seven trauma centers and registries in Europe and the United States of America was performed. We compared the BIG score with TRISS and PS09 scores in a population of blunt and penetrating trauma patients. We then assessed the discrimination ability of all scores via receiver operating characteristic (ROC) curves and compared the expected mortality rate (precision) of all scores with the observed mortality rate.
Results: In total, 12,206 datasets were retrieved to validate the BIG score. The mean ISS was 15 +/- 11, and the mean 30-day mortality rate was 4.8%. With an AUROC of 0.892 (95% confidence interval (CI): 0.879 to 0.906), the BIG score performed well in an adult population. TRISS had an area under ROC (AUROC) of 0.922 (0.913 to 0.932) and the PS09 score of 0.825 (0.915 to 0.934). On a penetrating-trauma population, the BIG score had an AUROC result of 0.920 (0.898 to 0.942) compared with the PS09 score (AUROC of 0.921; 0.902 to 0.939) and TRISS (0.929; 0.912 to 0.947).
Conclusions: The BIG score is a good predictor of mortality in the adult trauma population. It performed well compared with TRISS and the PS09 score, although it has significantly less discriminative ability. In a penetrating-trauma population, the BIG score performed better than in a population with blunt trauma. The BIG score has the advantage of being available shortly after admission and may be used to predict clinical prognosis or as a research tool to risk stratify trauma patients into clinical trials.

AB Introduction: The clinical use of serial quantitative computed tomography (CT) to characterize lung disease and guide the optimization of mechanical ventilation in patients with acute respiratory distress syndrome (ARDS) is limited by the risk of cumulative radiation exposure and by the difficulties and risks related to transferring patients to the CT room. We evaluated the effects of tube current-time product (mAs) variations on quantitative results in healthy lungs and in experimental ARDS in order to support the use of low-dose CT for quantitative analysis.
Methods: In 14 sheep chest CT was performed at baseline and after the induction of ARDS via intravenous oleic acid injection. For each CT session, two consecutive scans were obtained applying two different mAs: 60 mAs was paired with 140, 15 or 7.5 mAs. All other CT parameters were kept unaltered (tube voltage 120 kVp, collimation 32 x 0.5 mm, pitch 0.85, matrix 512 x 512, pixel size 0.625 x 0.625 mm). Quantitative results obtained at different mAs were compared via Bland-Altman analysis.
Results: Good agreement was observed between 60 mAs and 140 mAs and between 60 mAs and 15 mAs (all biases less than 1%). A further reduction of mAs to 7.5 mAs caused an increase in the bias of poorly aerated and nonaerated tissue (-2.9% and 2.4%, respectively) and determined a significant widening of the limits of agreement for the same compartments (-10.5% to 4.8% for poorly aerated tissue and -5.9% to 10.8% for nonaerated tissue). Estimated mean effective dose at 140, 60, 15 and 7.5 mAs corresponded to 17.8, 7.4, 2.0 and 0.9 mSv, respectively. Image noise of scans performed at 140, 60, 15 and 7.5 mAs corresponded to 10, 16, 38 and 74 Hounsfield units, respectively.
Conclusions: A reduction of effective dose up to 70% has been achieved with minimal effects on lung quantitative results. Low-dose computed tomography provides accurate quantitative results and could be used to characterize lung compartment distribution and possibly monitor time-course of ARDS with a lower risk of exposure to ionizing radiation. A further radiation dose reduction is associated with lower accuracy in quantitative results.

AB Introduction: Severe trauma is accompanied by a period of hypermetabolism and disuse. In this study, a rat model was used to determine the effects of burn and disuse independently and in combination on body composition, food intake and adipokines.
Methods: Male rats were assigned to four groups 1) sham ambulatory (SA), 2) sham hindlimb unloaded (SH), 3) 40% total body surface area full thickness scald burn ambulatory (BA) and 4) burn and hindlimb unloaded (BH). Animals designated to the SH and BH groups were placed in a tail traction system and their hindlimbs unloaded. Animals were followed for 14 days. Plasma, urine, fecal and tissue samples were analyzed.
Results: SA had a progressive increase in body mass (BM), SH and BA no change and BH a reduction. Compared to SA, BM was reduced by 10% in both SH and BA and by 17% when combined in BH. Compared to SA, all groups had reductions in lean and fat body mass with BH being greater. The decrease in lean mass was associated with the rate of urinary corticosterone excretion. The loss in fat mass was associated with decreases in plasma leptin and adiponectin and an increase in ghrelin. Following the acute response to injury, BH had a greater food intake per 100 g BM. Food intake was associated with the levels of leptin, adiponectin and ghrelin.
Conclusions: The effects of the combination of burn and disuse in this animal model were additive, therefore in assessing metabolic changes with severe trauma both injury and disuse should be considered. Furthermore, the observed changes in adipokines, corticosterone and ghrelin provide insights for interventions to attenuate the hypermetabolic state following injury, possibly reducing catabolism and muscle loss and subsequent adverse effects on recovery and function.

AB Clostridium botulinum is a species of spore-forming anaerobic bacteria defined by the expression of any one or two of seven serologically distinct botulinum neurotoxins (BoNTs) designated BoNT/A-G. This Gram-positive bacterium was first identified in 1897 and since then the paralyzing and lethal effects of its toxin have resulted in the recognition of different forms of the intoxication known as food-borne, infant, or wound botulism. Early microbiological and biochemical characterization of C. botulinum isolates revealed that the bacteria within the species had different characteristics and expressed different toxin types. To organize the variable bacterial traits within the species, Group I-IV designations were created. Interestingly, it was observed that isolates within different Groups could express the same toxin type and conversely a single Group could express different toxin types. This discordant phylogeny between the toxin and the host bacteria indicated that horizontal gene transfer of the toxin was responsible for the variation observed within the species. The recent availability of multiple C. botulinum genomic sequences has offered the ability to bioinformatically analyze the locations of the bont genes, the composition of their toxin gene clusters, and the genes flanking these regions to understand their variation. Comparison of the genomic sequences representing multiple serotypes indicates that the bont genes are not in random locations. Instead the analyses revealed specific regions where the toxin genes occur within the genomes representing serotype A, B, C, E, and F C. botulinum strains and C. butyricum type E strains. The genomic analyses have provided evidence of horizontal gene transfer, site-specific insertion, and recombination events. These events have contributed to the variation observed among the neurotoxins, the toxin gene clusters and the bacteria that contain them, and has supported the historical microbiological, and biochemical characterization of the Group classification within the species.

AB Many socially important search tasks are characterized by low target prevalence, meaning that targets are rarely encountered. For example, transportation security officers (TSOs) at airport checkpoints encounter very few actual threats in carry-on bags. In laboratory-based visual search experiments, low prevalence reduces the probability of detecting targets (Wolfe, Horowitz, & Kenner, 2005). In the lab, this "prevalence effect" is caused by changes in decision and response criteria (Wolfe & Van Wert, 2010) and can be mitigated by presenting a burst of high-prevalence search with feedback (Wolfe et al., 2007). The goal of this study was to see if these effects could be replicated in the field with TSOs. A total of 125 newly trained TSOs participated in one of two experiments as part of their final evaluation following training. They searched for threats in simulated bags across five blocks. The first three blocks were low prevalence (target prevalence <= .05) with no feedback; the fourth block was high prevalence (.50) with full feedback; and the final block was, again, low prevalence. We found that newly trained TSOs were better at detecting targets at high compared to low prevalence, replicating the prevalence effect. Furthermore, performance was better (and response criterion was more "liberal") in the low-prevalence block that took place after the high-prevalence block than in the initial three low-prevalence blocks, suggesting that a burst of high-prevalence trials may help alleviate the prevalence effect in the field.

AB In the U. S., the Department of Defense manages more than 5500 military installations that occupy approximately 12 million ha of land. These lands are used for various military training programs. Training activities inevitably degrade the land condition, and the degraded land condition, in turn, limits the land's military training carrying capacity. To sustain the military training land carrying capacity and the environment, land managers must monitor and predict changes to the land condition under various military training schemes. The objective of this study is to develop prediction models for land condition based on military training intensity and on independent variables that play a significant role in driving land condition changes at Fort Riley, Kansas. It is assumed that land condition can be quantified using soil erosion as a surrogate measure, which is mainly determined by a ground and vegetation cover factor, in which the larger the factor, the poorer the land condition. In addition to military training intensity, the independent variables used in these prediction models of land condition included distance from the location to roads, terrain slope (which affects military training access), ground cover, landscape fragmentation (an indirect measure of military training induced disturbance), and spatial variability of canopy cover and military training induced disturbance (as reflected in Landsat Thematic Mapper [TM] images). Various regression models were developed, and predictions made by linear and nonlinear models were compared with and without TM images, with and without stepwise regression procedures, and with and without historical land condition variables. Results showed that the absolute Pearson product moment correlation coefficients of ground cover with the cover factor were larger than 0.63; the correlation was greatest and significant at a risk level of 5%. Ground cover was thus involved in all the stepwise regression and nonlinear models. Although military training intensity was significantly correlated with the cover factor, training intensity was excluded from the best models mainly because both ground cover and landscape fragmentation that existed in the models also reflected the military training induced disturbance. Compared to models in which all the variables were involved, the stepwise regression models reduced the number of the independent variables from 11 or 15 to 3 or 6 (depending on analysis year) with no significant loss of accuracy. In most cases, adding the near and middle infrared TM images, which revealed the spatial variability of military training induced disturbance, improved the prediction of land condition. Based on the correlation coefficient and root mean square error (RMSE) between the predicted and observed values of the cover factor, the nonlinear models that used significant independent variables led to more accurate predictions than the linear regression models. This suggests that the combination of stepwise regression and nonlinear models could increase the accuracy of prediction. Moreover, adding the historical land condition variables, such as historical cover factor and ground cover, into the models could greatly decrease prediction errors.

AB Budget allocation to annual maintenance dredging projects conducted by the U.S. Army Corps of Engineers is addressed. Of the many projects requested, only a subset may be selected for funding because of budgetary constraints. The benefits of conducting maintenance dredging at one dredging project depend on other projects in the system that also are being dredged to take advantage of transportation efficiency gains derived from deeper navigable waterways. The proposed integer programming models and heuristic solution algorithms selected dredging projects for funding, while taking into account interdependent benefits. The models considered the waterway network topology, which was derived from flow data of historic waterborne cargo. The solution algorithms ensured efficient computational performance and quality of solutions. The models and algorithms were tested on example port systems from the Great Lakes region, as well as from mainline coastal ports and inland waterways. The models were shown to increase the amounts of system cargo throughput directly supported by dredging relative to traditional rank-order approaches that did not consider project interdependencies. This result was true especially for scenarios in which the overall budget was small relative to the total of all funding requests in question.

AB We consider the problem of distributed detection in a large network of sensors under network communication constraints. Sensor nodes are randomly deployed and follow a random sleep/wake schedule. When awake, sensor nodes perform local detection tests and communicate detections over a multiple-access channel to a fusion center. The fusion center can detect both successful communications and communication collisions in the channel. We show that the optimum fusion rule is a weighted sum of the number of detections received and the number of collisions detected by the fusion node. We derive analytical expressions that characterize the performance of the system. Simulation examples compare theoretical predictions with numerical results.

AB With heavy reliance on neurocognitive testing for concussion status assessments in the U.S. warfighter, there is a need to investigate the impact of testing environment on neurocognitive functioning. The current study compared scores on computerized neurocognitive tests of 166 soldiers who were deployed to Iraq. Predeployment baseline scores (n = 53) were compared to baseline scores collected while deployed (n = 113) on the battery of tests. There was no significant difference between baseline scores acquired from the predeployment group versus the deployed group. Furthermore, only one subtest revealed a significant difference in change scores from the follow-up test session when comparing the location of initial baseline testing. The results suggest that testing environment does not significantly influence baseline neurocognitive testing. The findings also provide support for the use of neurocognitive testing in a deployment environment.

AB As more engineered nanomaterials (eNM) are developed for a wide range of applications, it is crucial to minimize any unintended environmental impacts resulting from the application of eNM. To realize this vision, industry and policymakers must base risk management decisions on sound scientific information about the environmental fate of eNM, their availability to receptor organisms (eg, uptake), and any resultant biological effects (eg, toxicity). To address this critical need, we developed a model-driven, data mining system called NEIMiner, to study nanomaterial environmental impact (NEI). NEIMiner consists of four components: NEI modeling framework, data integration, data management and access, and model building. The NEI modeling framework defines the scope of NEI modeling and the strategy of integrating NEI models to form a layered, comprehensive predictability. The data integration layer brings together heterogeneous data sources related to NEI via automatic web services and web scraping technologies. The data management and access layer reuses and extends a popular content management system (CMS), Drupal, and consists of modules that model the complex data structure for NEI-related bibliography and characterization data. The model building layer provides an advanced analysis capability for NEI data. Together, these components provide significant value to the process of aggregating and analyzing large-scale distributed NEI data. A prototype of the NEIMiner system is available at http://neiminer.i-a-i.com/.

AB Background: Predictive modeling of the biological effects of nanomaterials is critical for industry and policymakers to assess the potential hazards resulting from the application of engineered nanomaterials.
Methods: We generated an experimental dataset on the toxic effects experienced by embryonic zebrafish due to exposure to nanomaterials. Several nanomaterials were studied, such as metal nanoparticles, dendrimer, metal oxide, and polymeric materials. The embryonic zebrafish metric (EZ Metric) was used as a screening-level measurement representative of adverse effects. Using the dataset, we developed a data mining approach to model the toxic endpoints and the overall biological impact of nanomaterials. Data mining techniques, such as numerical prediction, can assist analysts in developing risk assessment models for nanomaterials.
Results: We found several important attributes that contribute to the 24 hours post-fertilization (hpf) mortality, such as dosage concentration, shell composition, and surface charge. These findings concur with previous studies on nanomaterial toxicity using embryonic zebrafish. We conducted case studies on modeling the overall effect/impact of nanomaterials and the specific toxic endpoints such as mortality, delayed development, and morphological malformations. The results show that we can achieve high prediction accuracy for certain biological effects, such as 24 hpf mortality, 120 hpf mortality, and 120 hpf heart malformation. The results also show that the weighting scheme for individual biological effects has a significant influence on modeling the overall impact of nanomaterials. Sample prediction models can be found at http://neiminer.i-a-i.com/nei_models.
Conclusion: The EZ Metric-based data mining approach has been shown to have predictive power. The results provide valuable insights into the modeling and understanding of nanomaterial exposure effects.

AB Cell surface peptide display systems are large and diverse libraries of peptides (7-15 amino acids) which are presented by a display scaffold hosted by a phage (virus), bacteria, or yeast cell. This allows the self-sustaining peptide libraries to be rapidly screened for high affinity binders to a given target of interest, and those binders quickly identified. Peptide display systems have traditionally been utilized in conjunction with organic-based targets, such as protein toxins or carbon nanotubes. However, this technology has been expanded for use with inorganic targets, such as metals, for biofabrication, hybrid material assembly and corrosion prevention. While most current peptide display systems employ viruses to host the display scaffold, we have recently shown that a bacterial host, Escherichia coli, displaying peptides in the ubiquitous, membrane protein scaffold eCPX can also provide specific peptide binders to an organic target. We have, for the first time, extended the use of this bacterial peptide display system for the biodiscovery of aluminum binding 15mer peptides. We will present the process of biopanning with macroscopic inorganic targets, binder enrichment, and binder isolation and discovery.

AB The ability to conveniently and immediately test and diagnose in a diverse and rapidly changing environment is critical for field diagnostics. Smart biomedical sensors employ many different diagnostic/therapeutic methodologies; however, an ideal system would include the ability for results to be shared instantaneously with all members of the team through a software interface. We discuss our efforts towards the development and use of a robust, mobile platform (Android-based smart phone) that incorporates stable molecular recognition elements in sensor development. The inexpensive, compact, robust, archival, and portable design is ideal for rapid field diagnostics.

AB As software and methodology develop, key aspects of molecular interactions such as detailed energetics and flexibility are continuously better represented in docking simulations. In the latest iteration of the XPairIt API and Docking Protocol, we perform a blind dock of a peptide into the cleavage site of the Anthrax lethal factor (LF) metalloprotein. Molecular structures are prepared from RCSB:1JKY and we demonstrate a reasonably accurate docked peptide through analysis of protein motion and, using NCI Plot, visualize and characterize the forces leading to binding. We compare our docked structure to the 1JKY crystal structure and the more recent 1PWV structure, and discuss both captured and overlooked interactions. Our results offer a more detailed look at secondary contact and show that both van der Waals and electrostatic interactions from peptide residues further from the enzyme's catalytic site are significant.

AB Side effects of chemotherapy are major problems associated with current cancer treatment. An effective way to minimize these side effects and improve the efficacy of cancer treatment is to deliver drugs specifically targeted to tumors. This can be achieved by encapsulating chemotherapy drugs inside nanoparticles that aggregate in tumors due to the enhanced permeability and retention effect.
In order to monitor the delivery of nanoparticle-drug conjugates, it is important to develop systems that can image the nanoparticles. Since two-photon fluorescent probes can lead to significant reduction of background fluorescence compared to single photon fluorescent probes, two-photon fluorescent nanoparticles were developed through the miniemulsion process, using a conjugated polymer-poly [2-(3-thienyl)ethanol butoxycarbonyl-methyl urethane])-and two surfactants-sodium dodecyl sulfate (SDS) and cetyl trimethylammonium bromide (CTAB).
Nanoparticle size decreased as surfactant concentration increased, and particle size remained constant for surfactant concentrations above the critical micellar concentration (CMC), which was 8.2 mu M for SDS and 1 mu M for CTAB. The average size of the nanoparticles with surfactants at CMC was 31.67 nm for SDS nanoparticles and 25.60 nm for CTAB nanoparticles. Both nanoparticle systems exhibited strong one-photon and two-photon fluorescent signals. Fluorescence microscopy demonstrated these nanoparticles were able to penetrate rat cardiomyocytes. The results suggest these nanoparticles may potentially be used for high-contrast cell imaging.

AB Bacteria use an intricate set of communication systems for sensing and interpreting environmental cues that coordinate population-based behavior. Quorum sensing is one of these systems, and it involves the production, release, and detection of small chemical signaling molecules. Recent research has revealed the role of quorum sensing molecules in the control of microbial activities such as biofilm formation. In this presentation we outline the development of a recombinant E. coli cell-based sensor for detection of the quorum sensing molecule Autoinducer-2 (AI-2), as well as engineering strategies to remove sugar and anoxic inhibition of the strain.

AB This paper reports on the potential of a heterogeneous/homogeneous (HH) reactor for use as a fuel-flexible heat source, meeting the needs of the next generation of high temperature thermal-to-electric (TEC) portable power converters. In this class of reactor, low activation energy catalytic reactions provide a means to stabilize high activation energy homogeneous reactions. Diffusion limited surface reactions play a critical role in HH reactor operation. Surface conversion must be sufficiently fast to generate the high temperatures (similar to 1000 K) necessary to initiate gas phase reactions. Therefore, fuel diffusivity and the reactor dimension are important parameters in governing HH reactor operation. We examine the performance of an HH reactor fuelled by propane and n-dodecane, representing two extremes of liquid hydrocarbon diffusivity, as a function of confining reactor dimension. Unburned fuel/air mixtures are close to stoichiometric, which is an important factor in minimizing the amount of excess air and, therefore, balance of plant energy costs. At moderate levels of confinement, the reactor is capable producing high, uniform temperatures for both fuels.

Water and silica models have been created separately, relaxed and then put side by side to study the silica-water interface. All the intra- and inter-molecular interactions have been described by the reactive force field ReaxFF. From the molecular simulations, structural properties of water and silica, silica surface reactivity, diffusion of water molecule into silica have been investigated. For molecular simulations, open source MD code LAMMPS has been used.

AB Ballistic tests are performed on a continuous filament knitted aramid (CFKA) to determine the protective capabilities. CFKAs are candidates for implementation into garments that protect extremities, such as arms, legs, and the neck, from debris and other projectiles. These garments are expected to be designed at lower areal densities than conventional torso body armors, and have more demanding comfort requirements to accommodate flexible body joints. These unique requirements have prompted exploration of non-traditional armor materials such as knits and felts. The V-50 performance of a CFKA is compared to a woven aramid and commercial-off-the-shelf materials including: silk, polyester, Army Combat Uniform nylon-cotton blend fabric, staple yarn aramids, and aramid felts. Ballistic tests involve impacting each target multiple times with 0.22 caliber glass spheres in a pre-determined shot pattern. All targets are backed with ballistic gelatin and maximum likelihood estimation is used to calculate V50 values. Target areal densities range from approximately 200 g/m(2) to 1200 g/m(2). The results show that non-traditional materials like knits and felts can play an important role in extremity protection, and that unique design approaches are required for this emerging application area. Furthermore, the CFKA material appears to provide a unique combination of comfort and ballistic performance that may be well-suited to extremity protection applications.

AB In the present investigation novel needle-processed S2-glass laminates are fabricated and several key failure modes are characterized. Double cantilever beam testing shows that mode I fracture toughness improves up to 270% compared to non-needled baseline material. In-plane compressive strength of needled material improves by up to 475%. In plane tensile strength shows mixed results, improving by 6% for moderate volume fractions of through-thickness reinforcement (TTR) and decreasing by 6% at larger volume fractions. Double lap shear tests show that interlaminar shear strength improves as much as 17% for TTR inserted at +/- 45 degrees relative to the laminate plane.
X-ray micro-computed tomography (micro-CT) is used to investigate the unique 3D microstructure resulting from the needling process for 90 degrees TTR samples. The micro-CT reconstructions show that the dimensions of the disturbances of the in-plane fabric are significantly smaller than those imparted by the conventional tufting or stitching processes at each penetration site. Micro-CT reveals that some penetration sites are aggregates of closely spaced neighbors, resulting from the lack of precise spatial control with the needling process used in the present research. At these aggregate locations the in-plane disturbances are roughly equal in size to those from tufting/stitching.
Modifications to the automated processing equipment are shown and discussed. The modifications allow better spatial control at the penetration sites and the ability to insert TTR at +/- 45 degrees relative to the laminate plane.

ID SENSITIVITY-ANALYSIS; SIMULATIONS
AB In this work, the uncertainty in progressive failure of a composite is studied. Damage progression and failure of a composite is analyzed deterministically using the Generalized Method of Cells. Monte Carlo simulations are performed to determine the probabilistic distribution of the failure load and associated reliability. A new probabilistic methodology is employed that uses a single set of sample results to conduct a probabilistic sensitivity analysis, which can identify parameters that have significant or negligible influence on failure load. The accuracy of this approach is investigated. The methodology is verified using Monte Carlo simulation.

ID FIBER UNDULATIONS; STRENGTH
AB In filament wound composites, the combination of undulated fiber architecture and a compliant matrix introduces unique challenges in the prediction of stiffness and strength using traditional laminated composite theories. Available micromechanical models incorporating the effects of undulated fibers on the stiffness and strength of filament wound composites have not been evaluated with high fidelity experimental data. Therefore, the objective of the current investigation is to measure full-field strains and out-of-plane displacements in compressively loaded filament wound cylinders made with rigid and flexible matrix materials. A series of [+/-theta/89/+/-theta] cylinders with multiple helical fiber angles, winding patterns, and matrix materials were manufactured and tested. Digital image correlation was used to measure outside surface displacements and strains. Axial and hoop direction strain fluctuations within with the filament winding pattern were found to be of the order of 20-30% of the mean values throughout the cylinders. Qualitatively, these fluctuations can be related to non-classical elastic couplings in the anti-symmetric regions of the pattern. Winding pattern affected compressive strength only in the flexible matrix composite, while it did not affect the axial modulus of elasticity appreciably in either material system. Failure of the cylinder occurred by fiber microbuckling, which initiated near the crossing of circumferential and helical cross-over bands. Based on a statistical analysis of surface strains in the local fiber coordinate system, it was determined that fiber-and shear-direction strains at incipient microbuckling were two to four times greater than their respective global counterparts. These results indicate the magnitude of strain concentration existing in the cylinders immediately before failure and highlight the importance of fiber-and shear-direction strains in the failure process.

AB This paper presents an experimental investigation on the flexural response of 3D hybrid textile composites subjected to quasi-static three-point bending. The term "hybrid" here refers to different constituent fibers, including carbon, glass, and Kevlar, that are integrally woven into a single preform. Three different hybrid architectures, manufactured by varying the percentages and lay-ups of each constituent fiber, were examined to understand the effect of hybridization and the resulting performance enhancement, including the bending modulus, flexural strength, and strain to failure. Although the experimental results show architecture-dependent flexural response, fiber tow kinking on the compressive side of the specimen is determined to be a strength limiting mechanism for this class of materials.

AB A new approach to predict the service life of critical components via study of damage precursors is emerging and is the topic of this paper. To date most service life predictions are based on measurements of damage indicators and their growth towards criticality or failure, e.g. fatigue crack length, material loss due to corrosion or wear, etc. For many cases of concern, especially fatigue, the critical, direct damage indicator, D-i, i.e. crack length, increases exponentially towards criticality, roughly
dD(i)/dN alpha D-i(n)
where n can exceed 4. This makes lifetime estimates based on measurements of damage, e.g. around half-life, or even at 80 percent life, difficult and inaccurate, even for cases where the damage progress is well modeled and understood. To improve the accuracy and reliability of lifetime prediction, efforts are now underway to determine the state awareness of a critical component during service, based on property characterizations, in addition to the measurements of the direct damage indicators, such as crack length, acoustic emission, ultrasound signals, eddy current measurements, etc. These characterizations will include indirect damage indicators, i.e. precursors, and allied or affiliated damage indicators. Precursors, e.g. to fatigue crack formation, include electrical resistivity changes, dislocation distribution changes and crazing. For affiliated damage indicators residual stress relaxation or development, phase changes, electrical property (resistivity, dielectric constant, permeability), microstructural characterization, must be considered. The selection of the optimal combination of direct and indirect damage indicators will be application specific. For example for ultra-high strength steels and aluminum alloys, with high damage exponents n, where the critical crack length may also be very small and difficult to detect, measurements of reliable precursors and indirect damage indicators could significantly improve service life prediction. It is proposed to assess the efficacy of damage indicators on the basis of their D-i/D(f)vs.N-i/N-f, i.e. damage ratio vs. life fraction curves, (referred to as damage indicator ratio curves, or DIR curves) searching for indicators with DIR curves that best meet the needs of the application.

ID POLYMERS
AB Glass-epoxy composite structures are frequently used in many aerospace applications, such as landing gear struts, satellite frames, aircraft nose cones, and interior fuselage stiffeners. In glass fiber/epoxy composite systems, damage precursors such as micro-cracking have significant implications in impacting the performance and life span of the structure. As a consequence, it is necessary to gain a better understanding of the response under fatigue loading. The focus of this study is to identify the stress levels responsible for crazing, micro-crack formation and coalescence into macrocrack in S2 Glass Cycom381 Epoxy matrices (8 plies woven). Fatigue tests are performed at 1, 100, 1,000, 10,000, 100,000, and 1,000,000 cycles under tensile loading conditions (R=0.1). Strategies for monitoring the damage prior to, during, and after cyclic loading conditions include ultrasound and acoustic emission (AE) non-destructive evaluation techniques. AE is used during the fatigue loading tests to identify and localize real-time the presence of rupture, delamination, and crack formations. The high frequency ultrasound immersion technique is conducted for high fidelity interlaminar evaluation prior to fatigue testing. After each test, an examination of the fracture surface is conducted by several image characterization techniques including optical microscopy and Scanning Electron Microscopy (SEM). By this systematic evaluation, the phenomena of crazing, the propagation of micro-cracks, delaminations and other factors that lead to catastrophic failure are investigated. At the end of this study, an empirical framework is developed that maps the relationship between the sizing and location of the damage pre-cursors and the corresponding matrix/fiber degradation mechanisms.

AB Steroidal and adamantane aminoacridine derivatives were prepared and tested as both botulinum neurotoxin (BoNT) inhibitors and antimalarials.. Steroid-bound acridines provided good potency against both the BoNT/A and BoNT/B light chains (LCs). The observed inhibition of the BoNT/B LC by ca. 50 % is the highest attained inhibitory activity against this serotype by acridine-based compounds to date. With respect to the antimalarial activity, the adamantane acridines were the most potent derivatives (IC50 = 6-9 nM, SI>326), indicating that an adamantyl group is a better carrier than a steroidal motif for this indication.

AB The Department of Defense (DoD) is currently maintaining the aircraft operability and functionality past the original design intention for many military aircraft. This practice imposes an additional burden on the inspection systems at the DoD logistic centers to ensure the aircraft in operation are airworthy and will be able to complete mission assignments for a specified period of time. Condition-Based Maintenance Plus (CBM+) has evolved into the U.S. Army leader priority program and becomes a critical technology for the future of the Army to reduce the logistic footprint, maximize the aircraft availability, and increase the component time on wing. To achieve these goals, the Army Research Laboratory (ARL) has initiated the CBM+ Science and Technology (S&T) Enterprise that spreads across ARL research organizations and supports the Army Research, Development, and Engineering Command CBM+ initiative in the Army fleet. The CBM+ S&T Enterprise has three Integrated Product Teams (IPTs), which focus on Hardware and Sensing, Prognostics and Diagnostics, and Data Transfer and Fusion Architecture technologies. The fourth IPT is the Technology Demonstration and Integration.
It has been established that CBM, when joined with the system and/or sub-system prognostic capability (CBM+), could result in tremendous inspection savings, improved aircraft safety and availability, and decreased aircraft downtime and maintenance costs. Under these IPTs, diverse research efforts are being conducted and coordinated by the Technology Focus Working Groups (TFWGs) to combine diagnostics and prognostics capabilities. TFWGs concentrate on many technologies and processes including Structural Health Monitoring (SHM) and Maintenance Credit Validation. One of the challenges for researchers has been the development of the SHM capability that is not only effective and reliable but also relatively low cost and easy to install and maintain while performing the desired function of monitoring DoD systems and sub-systems for loss of structural integrity. SHM methods can be used to monitor the condition of critical structural components and, with other technologies, can determine the structural remaining useful life. As a result, potential maintenance credits, e.g., increased time-between-overhaul or fatigue life adjustment, can be formulated and proposed. Formulated maintenance credits are based on full understanding of physics of failure of monitored components, direct and/or indirect data that may contain some uncertainties, and methodologies that may be complex and advanced.
This paper will document the ARL CBM+ S&T Enterprise strategies in supporting the Army CBM+ implementation goals and developing a process to validate maintenance credits or formulate maintenance-related decisions. Examples of CBM+ actions include the formulation of usage credits and early replacement of monitored parts before using up its component retirement life.

ID MOISTURE DAMAGE; PERFORMANCE; MIXTURES
AB This paper presents the results of tests of warm-mix asphalt (WMA) mixtures designed for airfield pavements. The study was conducted in two phases. The first phase included laboratory tests on 11 WMA technologies. The tests in Phase 2 were performed on three WMA mixtures and one hot-mix asphalt (HMA) mixture produced in an asphalt plant. The evaluation included performance tests to assess WMA susceptibility to permanent deformation and moisture damage compared with that of HMA produced with the same aggregate blend. Test results indicated that WMA potentially was a viable product for surface mixtures on airfield pavements. Although WMA exhibited poorer performance than BMA in moisture damage tests on laboratory-produced specimens, the plant-produced mix indicated little difference compared with HMA. Rutting potential for WMA was somewhat greater than for HMA for mixtures produced both in the laboratory and in an asphalt plant according to asphalt pavement analyzer and Hamburg wheel tracking tests. Differences in performance of WMA mixtures were not attributed to a specific WMA technology category. Variations in performance test results between laboratory-produced specimens and plant-produced specimens were noted and indicated a need to require performance testing as part of a comprehensive quality assurance plan.

While still imperfect, today's military command posts represent centuries of refinement and maturation enhanced by cutting-edge technology. Cyberspace's emergence as an operational domain, however, presents unresolved challenges to this status quo. Techniques for maintaining situational awareness and command and control of cyber operations, particularly joint cyber/kinetic operations, are ill-defined, and no current solutions provide military decision-makers with a comprehensive cyber common operating picture, or CCOP. This paper provides a framework for designing such systems. We focus on the problem of cyber-only operations as well as joint cyber-kinetic operations. Our analysis indicates that the CCOP problem is tractable, but non-trivial, requiring substantial effort realized through evolutionary and revolutionary research approaches.

AB With the recognition of cyberspace as a warfighting domain by the U. S. Department of Defense, we anticipate increased use of malicious software as weapons during hostilities between nation-states. Such conflict could occur solely on computer networks, but increasingly will be used in conjunction with traditional kinetic attack, or even to eliminate the need for kinetic attack. In either context, precise targeting and effective limiting of collateral damage from cyber weaponry are desired goals of any nation seeking to comply with the law of war. Since at least the Morris Worm, malicious software found in the wild has frequently contained mechanisms to target effectively, limit propagation, allow self-destruction, and minimize consumption of host resources to prevent detection and damage. This paper surveys major variants of malicious software from 1982 to present and synthesizes the control measures they contain that might limit collateral damage in future cyber weapons. As part of this work, we provide a framework for critical analysis of such measures. Our results indicate that a compelling framework for critical analysis emerges by studying these measures allowing classification of new forms of malware and providing insight into future novel technical mechanisms for limiting collateral damage.

AB The microwave ceramic Ba(Y,Sb)(0.05)Ti0.90O3, based upon random B-site dipole-like substitutions is structurally and electrically characterized over the temperature range -55 degrees C to 120 degrees C. X-ray diffraction information coupled together with scanning electron microscopy reveals that the material is single phase and has submicron grain sizes. Results show the tetragonal phase ranges from -30 degrees C to 200 degrees C, which is a broader temperature range than that of the parent material BaTiO3, 0 degrees C to 120 degrees C. The material Ba(Y,Sb)(0.05)Ti0.90O3 also has a diffuse relative high dielectric constant of about 10,000 that peaks at the orthorhombic-tetragonal structural phase transition around -30 degrees C.

AB This paper presents the formulation of distributed Kalman-Bucy filter algorithm for a network of autonomous sensors, which is modeled as a connected undirected graph. Development of the distributed Kalman-Bucy filter is formulated as two average consensus problems in terms of weighted inverse of measurement noise covariance matrices and weighted measurements. The proposed algorithm utilizes the static average consensus protocol to solve the first consensus problem and the proportional-integral based dynamic average consensus protocol to solve the latter. The distributed Kalman-Bucy filter algorithm is optimal in the sense that the performance of the proposed algorithm asymptotically approaches that of a centralized filter. Numerical simulations are presented to demonstrate the performance of the proposed scheme.

DE metamaterials; anisotropic Green's function; Hertzian Dipole
AB In this paper, the excitation of lateral (surface) waves in a layered media consisting of a ground plane, a metamaterial layer and free space is investigated. It is presumed an effective media approximation yields the anisotropic constitutive parameters for the metamaterial layer. Using these approximations, Green's functions are developed for the electromagnetic fields resulting from a Hertzian dipole excitation located at the metamaterial and free space interface. As the formulation of the problem is accomplished in the spectral domain, the strength of the lateral waves is found from the residues of poles circled in the complex plane. This is first done for the case of an anisotropic media in the x- and y- directions (parallel to the ground plane). Because the unit cell patterning of the metamaterials gives the microwave designer increased flexibility, it is possible to undertake a similar analysis using anisotropic constitutive parameters expressed in cylindrical coordinates. This analysis is fundamental for applied microwave applications such as the realization of an antenna on a layered media and demonstrates the enormous design flexibility made possible for metamaterials.

AB The opportunity for wounded servicemembers (SMs) to return to high-level activity and return to duty has improved with advances in surgery, rehabilitation, and prosthetic technology. As a result, there is now a need for a high-level mobility outcome measure to assess progress toward high-level mobility during and after rehabilitation. The purpose of this study was to develop and determine the reliability of a new outcome measure called the Comprehensive High-Level Activity Mobility Predictor (CHAMP). The CHAMP consists of the Single Limb Stance, Edgren Side Step Test, T-Test, and Illinois Agility Test. CHAMP reliability was determined for SMs with lower-limb loss (LLL) (interrater: n = 118; test-retest: n = 111) and without LLL (n = 97). A linear system was developed to combine the CHAMP items and produce a composite score that ranges from 0 to 40, with higher scores indicating better performance. Interrater and test-retest intraclass correlation coefficient values for the CHAMP were 1.0 and 0.97, respectively. A CHAMP score equal to or greater than 33 points is within the range for SMs without LLL. The CHAMP was found to be a safe and reliable measure of high-level mobility in SMs with traumatic LLL.

AB This study examined the convergent construct validity of a new performance-based assessment instrument called the Comprehensive High-Level Activity Mobility Predictor (CHAMP) as a measure of high-level mobility in service-members (SMs) with traumatic lower-limb loss (LLL). The study was completed by 118 SMs. Convergent construct validity of the CHAMP was established using the 6-minute walk test (6MWT) as a measure of overall mobility and physical function and the Amputee Mobility Predictor (AMP) as a measure of basic prosthetic mobility. The known group methods construct validity examined disparities in high-level mobility capability among SMs with different levels of LLL. The CHAMP score demonstrated a strong positive relationship between 6MWT distance (r = 0.80, p < 0.001) and AMP score (r = 0.87,p < 0.001), respectively. In addition, the CHAMP can discriminate between different levels of LLL. Study findings support the CHAMP as a valid performance-based assessment instrument of high-level mobility for SMs with traumatic LLL.

AB The rehabilitation of U.S. military servicemembers (SMs) who have sustained a traumatic loss of one or both lower limbs requires outcome measures that can assess their physical capabilities in comparison with their uninjured colleagues. Describing reference ranges for the 6-minute walk test (6MWT) in both populations will help clinicians develop appropriate goals for rehabilitation and document progress toward those goals. A convenience sample of 118 male U.S. SMs with and 97 without traumatic lower-limb loss participated in this study. All participants completed a 6MWT, and comparisons were made between SMs with and without limb loss and among the levels of limb loss. The SMs without lower-limb loss performed significantly better than all SMs with lower-limb loss. The SMs with transtibial limb loss performed significantly better than those with all other levels of limb loss. Statistically significant and clinically relevant differences were also noted between the other levels of limb loss. No differences were found between different prosthetic components. Reference ranges were established for U.S. SMs with and without various levels of limb loss, and the 6MWT was able to identify functional differences between groups.

AB Performance-based outcomes such as the T-Test, Edgren Side Step Test (ESST), and Illinois Agility Test (IAT) have been used to assess agility in athletes and nonathletes; however, the reliability and validity of these tests have not been established. The purpose of this study was to establish the reliability and convergent construct validity of the ESST, T-Test, and IAT in young, nondisabled, physically active male servicemembers (SMs). Ninety-seven male Active Duty U.S. Army SMs completed the study. Statistically significant differences were not found between the ESST (p = 0.10), T-Test (p = 0.09), and IAT (p = 0.23) when administered twice within a 24 to 48 h period. These tests were found to have excellent interrater reliability and moderate to good test-retest reliability. A good positive relationship exists between the IAT and T-Test (r = 0.76, p < 0.001) and a moderate negative relationship exists between the ESST and both the T-Test (r = -0.69, p < 0.001) and IAT (r = -0.65, p < 0.001). The results suggest that these tests are valid measures of agility that uniquely assess movement in different planes, thus providing a comprehensive assessment of high-level mobility.

AB The purpose of this study was to examine the possible relationship between factors modifiable by rehabilitation interventions (rehabilitation factors), other factors related to lower-limb loss (other factors), and high-level mobility as measured by the Comprehensive High-Level Activity Mobility Predictor (CHAMP) in servicemembers (SMs) with traumatic lower-limb loss. One-hundred eighteen male SMs with either unilateral transtibial amputation (TTA), unilateral transfemoral amputation (TFA), or bilateral lower-limb amputation (BLLA) participated. Stepwise regression analysis was used to develop separate regression models of factors predicting CHAMP score. Regression models containing both rehabilitation factors and other factors explained 81% (TTA), 36% (TFA), and 91% (BLLA) of the variance in CHAMP score. Rehabilitation factors such as lower-limb strength and dynamic balance were found to be significantly related to CHAMP score and can be enhanced with the appropriate intervention. Further, the findings support the importance of salvaging the knee joint and its effect on high-level mobility capabilities. Lastly, the J-shaped energy storage and return feet were found to improve high-level mobility for SMs with TTA. These results could help guide rehabilitation and aid in developing appropriate interventions to assist in maximizing high-level mobility capabilities for SMs with traumatic lower-limb loss.

Twenty-One-Year Field Performance
SO TRANSPORTATION RESEARCH RECORD

DT Article
AB In 1989, the U.S. Army Engineer Research and Development Center and Crafco, Inc., initiated a research effort to develop improved materials and processes for sealing joints in portland cement concrete pavements. Objectives were to develop specifications for improved hot-applied, jet fuel resistant (JFR) and non jet fuel resistant (non-OR) sealants and to determine the impact of installation configuration on field performance. The laboratory phase identified desired sealant properties, evaluated sealants for those properties, and developed sealants with improved low-temperature and aging properties. The field phase was installed in June 1991 at Fairchild Air Force Base, Washington, to determine performance of developed sealants compared with standard sealants and to determine whether performance could be improved by changing installation geometry. Thirteen sealants were installed. The field study documented installation and evaluations at 6 and 12 months. After study completion, the installations were monitored several additional times. Detailed papers were prepared after Sand 10 years. At 10 years, some sealants had greater than a 10-year life. In 2011, the installations reached 20 years of age. The JFR sections had been replaced, and non-JFR sections were still intact and were evaluated in April 2012. Results of the 21-year evaluation are presented. One silicone sealant and the improved non-JFR sealant achieved a 21-year life. Results also show that the flush-fill installation geometry increased life of the hot-applied asphalt sealants by more than 50% compared with the standard recessed configuration and should be considered for joint sealant installations.

The results show an increased potential for energy extraction from naturally occurring vibration sources. An analytical model was used to model the effective mechanical properties of multilayered MEMS cantilevers while the natural frequencies were obtained by applying a finite element code. Results were obtained for two geometries of arc-based cantilevers as well as their linear counterparts. These results demonstrate that arc-based cantilevers vibrate at frequencies significantly lower than their linear components (up to 40% reduction in natural frequency).

AB Development of a robust Kalman filter for uncertain stochastic systems under persistent excitation and unknown measurement model is presented. The given discrete-time stochastic formulation does not require the knowledge of any bounds on parametric uncertainties and excitations. When there are no system uncertainties, the performance of the proposed robust estimator is similar to that of the traditional Kalman filter and the proposed approach asymptotically recovers the desired optimal performance in the presence of uncertainties and/or persistent excitation.

AB This paper presents a linear matrix inequality (LMI)-based robust fault detection and isolation scheme that can precisely detect/isolate simultaneously occurring actuator and sensor faults within uncertain linear stochastic systems. This robust fault detection scheme would be able to distinguish between model uncertainties and actuator failures, therefore eliminating the problem of false alarms even in the presence of matched uncertainties. The proposed approach can also be used for sensor fault identification and the reconstruction of true outputs from faulty sensor outputs. Simulation results presented here validate the effectiveness of the proposed robust fault detection and isolation system.

DE Experience-aided; Analytical Reasoning
AB Cyber analysis is a difficult task for analysts due to huge amounts of noise-abundant monitoring data and increasing complexity of the reasoning tasks. Therefore, experience from experts can provide guidance for analysts' analytical reasoning and contribute to training. Despite its great potential benefits, experience has not been effectively leveraged in the existing reasoning support systems due to the difficulty of elicitation and reuse. To fill the gap, we propose an experience-aided reasoning support system which can automatically capture experts' experience and subsequently guide the novices' reasoning in a step-by-step manner. Drawing on cognitive theory, we model experience as a reasoning process involving "actions", "observations", and "hypotheses". Computability and adaptability are the comparative advantages of this model: the "hypotheses" capture analysts' internal mental reasoning as a black box, while the "actions" and "observations" formally representing the external context and analysts' evidence exploration activities. This paper demonstrates how this system, built on this experience model, can capture and utilize experience effectively.

AB A previously unrecognized type of gas fractionation occurs in firn air columns subjected to intense convection. It is a form of kinetic fractionation that depends on the fact that different gases have different molecular diffusivities. Convective mixing continually disturbs diffusive equilibrium, and gases diffuse back toward diffusive equilibrium under the influence of gravity and thermal gradients. In near-surface firn where convection and diffusion compete as gas transport mechanisms, slow-diffusing gases such as krypton (Kr) and xenon (Xe) are more heavily impacted by convection than fast diffusing gases such as nitrogen (N-2) and argon (Ar), and the signals are preserved in deep firn and ice. We show a simple theory that predicts this kinetic effect, and the theory is confirmed by observations using a newly-developed Kr and Xe stable isotope system in air samples from the Megadunes field site on the East Antarctic plateau. Numerical simulations confirm the effect's magnitude at this site. A main purpose of this work is to support the development of a proxy indicator of past convection in firn, for use in ice-core gas records. To this aim, we also show with the simulations that the magnitude of the kinetic effect is fairly insensitive to the exact profile of convective strength, if the overall thickness of the convective zone is kept constant. These results suggest that it may be feasible to test for the existence of an extremely deep (similar to 30-40 m) convective zone, which has been hypothesized for glacial maxima, by future ice-core measurements.

AB Lung cancer first line treatment has been directed from the non-specific cytotoxic doublet chemotherapy to the molecular targeted. The major limitation of the targeted therapies still remains the small number of patients positive to gene mutations. Furthermore, the differentiation between second line and maintenance therapy has not been fully clarified and differs in the clinical practice between cancer centers. The authors present a segregation between maintenance treatment and second line and present a possible definition for the term "maintenance" treatment. In addition, cancer cell evolution induces mutations and therefore either targeted therapies or non-specific chemotherapy drugs in many patients become ineffective. In the present work pathways such as epidermal growth factor, anaplastic lymphoma kinase, met proto-oncogene and PI3K are extensively presented and correlated with current chemotherapy treatment. Future, perspectives for targeted treatment are presented based on the current publications and ongoing clinical trials.

AB A methodology is demonstrated for the rapid evaluation of the bulk electrolyte characteristics of the salt lithium difluoro(oxalato)borate (LiDFOB) (or lithium oxalyldifluoroborate (LiODFB)). Acetonitrile (AN) has been used as a model solvent. Utilizing information from a combination of methods-i.e., the determination of the (AN)(n)-LiDFOB thermal phase behavior (phase diagram and the corresponding solvate crystal structures), a Raman spectroscopic evaluation of the solvation/ionic association interactions and molecular dynamics (MD) simulations-detailed insight into the coordination interactions of the DFOB- anion is obtained and explanations are readily available for the solution behavior and variability in the transport properties (viscosity and ionic conductivity) of AN solutions with this salt relative to other lithium salts.

SO JOURNAL OF THE ELECTROCHEMICAL SOCIETY

ID NONAQUEOUS SOLVENTS; SPINEL OXIDES; BATTERIES
AB LNMO/LTO cells represent an excellent vehicle with which to test the impact of electrolyte additives on cell performance due to the high potential of LNMO which leads to electrolyte oxidation. Additives that prevent this oxidation are desired. Electrolyte additive researchers normally compare the capacity retention versus cycle number of cells with and without additives. If the capacity retention is improved, the additive is "good". In this paper, this logic is shown to be flawed. One additive, LiO-t-C4F9, which does improve capacity retention versus cycle number, is shown to do so by increasing electrolyte oxidation at the positive electrode. This causes increased charge end point capacity slippage and increased self discharge rates. As such, these additives, like many promoted in the literature, are not "good", but are "bad". On the other hand, one additive, Al(HFiP)(3), is shown to reduce parasitic reactions at the LNMO electrode but does not lead to improved capacity retention. A full understanding of the impact of the additive on the parasitic reaction rates at both positive and negative electrodes is required before a sound judgment about the impact of an additive can be made. Therefore, additive researchers must pay attention to coulombic efficiency, capacity end point slippage, reversible and irreversible capacity loss during storage as well as voltage drop during storage in addition to the long-time cycling performance for cells to get an overall evaluation of electrolyte additives.

AB PC-based games are currently being used for military training, but the instructional and motivational features of such technology are not well understood. To identify features of training games that influence instruction and motivation, a popular first-person-perspective game with a military theme was analyzed empirically. Twenty-one participants played the "basic training" portion of the game, which included Army background information, virtual marksmanship training, an obstacle course, virtual weapons familiarization, and an urban terrain training mission. The results of this research provide useful information to individuals developing training games, desktop simulations, and interactive multimedia course-ware to meet optimal training objectives and strategies.

AB Improving human systems integration through technologically advanced training and performance aids has become increasingly important to military transformation. Measures of improved cognitive and coordination processes arising from the employment of transformational tools are necessary to guide the refinement and future development of such technologies. In this article, we describe a cognitive load theory approach to developing a combinatory measure of individual workload and team performance following an experimental intervention involving training and a decision support system. We discuss how indicators of what we term team cognitive efficiency can improve assessing the effectiveness of transformational processes and technologies.

AB We examined the effects of climate (i.e. temperature, precipitation, moisture index, river discharge) on the radial growth of eastern white pine (Pious strobus) in two contrasting microhabitats (floodway versus terrace) in relation to an elevational and moisture gradient along the banks of the Red Cedar River, Michigan. We hypothesized that trees growing on the terrace sites would have a greater sensitivity to climatic factors than trees growing in the floodway. Increment cores were sampled and crossdated from dominant and co-dominant trees in the floodway and terrace sites and standardized growth chronologies were developed. Mean sensitivity, standard deviation, percentage of absent rings, and intertree correlation were generally greater for eastern white pine on the terrace compared to the floodway forests. Dendroclimatic relationships were examined with bootstrapped correlation analysis, which indicated that radial growth of eastern white pine in both floodway and terrace sites was negatively associated with summer temperature (i.e. June and July) of the current growing season. Radial growth in both floodway and terrace sites were positively related to current May precipitation, moisture index, and river discharge. Dendroclimatic response of eastern white pine in floodway and terrace sites differed in that the effect of summer moisture stress was more persistent in the terrace sites into later summer (i.e. current July) whereas floodway sites showed a negative response to prior-year May precipitation and moisture index. Although precipitation and hydrological conditions of the river were generally favorable during the summer months, which appeared to have promoted soil moisture recharge, flooding in early winter (i.e. prior November) had a negative impact on growth in both microhabitats. The effect of winter river discharge was significantly negative in January (t) in the floodway sites compared to the terrace sites.

AB Soldiers know firsthand the criticality of having mission essential supplies and equipment arrive at the right place, at the right time. This is of particular importance when operating in remote locations around the world where hostilities are prevalent, terrain is restrictive and mission accomplishment has strategic implications. The Joint Precision Airdrop System (JPADS) is a guided logistical resupply platform that delivers supplies and equipment in a precise manner to Soldiers operating in restrictive or hostile terrain from a high altitude when conventional means of resupply are unavailable, unrealistic or ill-advised. Our current force structure requires a system that can operate in a dynamic and mercurial environment in order to rapidly adjust to changes on the ground. The research paper will explore the JPADS from a Systems Architecture perspective in order to decompose the system and provide critical system details, which will aid in the Design Structure Matrix (DSM) analysis that will follow. The outcome of this research is to not only provide recommendations to the project sponsors working on the JPADS, but to illustrate the value of using Systems Engineering methodologies and tools to analyze complex systems and challenges.

DE Federal Air Marshal Service; Value Focused Thinking
AB The Federal Air Marshal Service's (FAMS) mission is to promote confidence in the nation's civil aviation system through effective deployment of Federal Air Marshals (FAMs) to detect, deter, and defeat hostile acts targeting United States air carriers, airports, passengers, and crews. To accomplish this mission, the FAMS has established field offices across the United States and assigned marshals to these offices. As with all of government, the FAMS continues to work to operate efficiently as well as effectively. To this end, they seek to determine the best field office and marshal assignment set to maximize risk coverage at the minimum cost.
In this work, we take a two-phased approach to solve this problem: risk assessment and field office allocation. In the first phase, we use Value Focused Thinking (VFT) to formulate a detailed risk profile for each flight. In the second phase, we iteratively apply a separate application of VFT in a heuristic manner to determine the best from a set of assignment/field office alternatives until we achieve a near-optimal solution. Then, we use cost benefit analysis to decide among the final candidate solutions.
The results provided in this study will be used by the FAMS to realign their field offices and the marshal allocation as well as provide the analytic rigor to defend their future budget submissions to Congress. Due to the sensitive nature of the assignment information, our presentation will focus on our approach and use derived vice actual data to obtain a solution set.

AB In autonomous ground systems, developing a clear model of the surroundings is crucial for operating in any environment. Three-dimensional light detection and ranging (LIDAR) sensors, such as the Velodyne HDL-64E S2, are powerful tools for robotic perception. However, these sensors generate large data sets exceeding one million points per second that can be difficult to use on space, power, and processing constrained platforms. We report on GPU assisted processing within a Robotic Operating System (ROS) environment capable of achieving greater than an order of magnitude reduction in point cloud ground segmentation processing time using a gradient field algorithm with only a small increase in power consumption.

AB This paper identifies the need for a standard method of benchmarking emerging robotic systems with a focus on military, multi-robot convoys. Benchmarking is commonly used throughout academia and industry as a method of evaluating and comparing products. In this paper we propose a generic form that these benchmarks may take in the future. Classification categories, such as, obstacle avoidance, area mapping, and convoy coherence are all possible elements of this benchmark. The goal is a standard benchmark that can be used to evaluate military multi-robot convoy systems.

AB Covalent attachment of pre-formed nanosilica particles to the surface of ultra-high molecular weight polyethylene (UHMWPE) was attained through a grafting reaction using 3-glycidoxypropyltrimethoxysilane (GPS) once the surface had been exposed to a plasma treatment. Scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and contact angle measurements showed a change in both the morphology and composition of the surface with the appearance of micro-depressions, grafting of oxygen containing functional groups, and improved wettability upon exposure to the plasma. Attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and Rutherford backscattering spectrometry (RBS) confirmed that plasma activation and a silane intermediary were required for the efficient chemical grafting of the nanosilica. Attempts at grafting the nanosilica to as-received polyethylene films proved unsuccessful due to the absence of covalent bonding sites.

ID DIELECTRIC BARRIER DISCHARGE; SURFACE MODIFICATION; POLYMERS
AB Non-thermal atmospheric-pressure plasmas, specifically dielectric barrier discharges (DBDs), have attracted significant attention due to their ease of formation of stable plasmas, low cost of operation, fast materials processing, and scalability. Furthermore, DBDs have been shown to be effective in functionalizing the surface of polymeric materials. In this study, the surface of ultra-high molecular weight polyethylene (UHMWPE) films was treated with He-air, He-H2O, He-O-2, and He-N-2 dielectric barrier discharges to assess the effect of the surface functionalization on their adhesion strength. Changes in wettability, surface chemistry, and surface morphology were studied using water contact angle goniometry, x-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM), respectively. Adhesion was assessed using T-peel tests on all samples using a polyurethane adhesive. Results indicate that samples treated with He-H2O and He-O-2 plasmas had similar oxygen functionalities, however, He-O-2 plasmas caused significantly more roughening of the surface than He-H2O plasma. He-air and He-N-2 plasmas showed nitrogen incorporation to the surface in the form of amine, and possibly nitrate and amide groups, with the highest concentration at 4 atomic percent. In addition, He-air and He-N-2 plasmas were highly filamentary which caused increased roughness to the surface. Furthermore, He-air and He-N-2 had, similarly, high adhesion strength although they did not show the highest roughness. The adhesion strength of UHMWPE films exhibited the following trend He-air > He-N-2 > He-O-2 > He-H2O. These results indicate that He-air or He-N-2 plasmas are effective in treating polymer surfaces for adhesion purposes.

AB Among the various functions of the paddlefish rostrum, it is also believed to serve as a stabilizer to counteract the downward force that would otherwise occur during the process of filter feeding. From its unique shape, it is hypothesized that the paddlefish rostrum serves to generate a substantial amount of lift that naturally occurs as the rostrum is elevated at the same time the fish opens its mouth. The present, numerical study is an attempt to quantify the amount of lift (and drag) that is generated by the rostrum of a juvenile paddlefish. Additionally, this data is compared with other hydrofoils. The results suggest that the paddlefish rostrum does indeed produce substantial lift at certain angles of attack. In fact, the results indicate that the amount of lift is comparable to that produced by a symmetric foil (NACA 0012).

AB This study examined the protective effects of hardiness (dispositional resilience) on self-reported posttraumatic stress disorder (PTSD) symptoms in a sample of postdeployed service members. Hardiness was negatively related to PTSD symptoms. Time in the military, number of deployments, and total time spent on deployment were all positively related to PTSD symptoms. Hardiness moderated the effects of time in the military on PTSD symptoms, such that time in the military had no effect on those who were high in hardiness. Hardiness did not moderate the effects of either deployment measure. Suggestions to modify current military resilience training programs to most effectively enhance the benefits of hardiness are discussed.

AB The U.S. military has developed prophylactic interventions to mitigate effects from stress. The project reported is a first of its kind descriptive assessment of the delivery of resilience training in a deployed environment. The Connor-Davidson Resilience Scale and an inventory of stress, morale, performance, and use of specific behaviors were administered before and after resilience training was implemented for all personnel assigned to a military facility in Afghanistan. There was a small positive relation between resilient thinking and self-reported morale, but, despite the training, both resilient thinking and morale were observed to decline across the deployment period. This descriptive effort can provide some baseline for commanders' expectations in implementation of resilience training.

AB We evaluated the efficacy of a computer-based situation awareness (SA) measurement system for training dismounted infantry SA in an urban terrain virtual reality (VR) simulation. Based on past research, we hypothesized that the SA measures would be sensitive to individual (squad leader) differences, and that the frequency of specific probes would reveal differences in critical SA requirements among scenarios. Three infantry squads performed multiple trials across two different scenarios. A confederate platoon leader posed probes to squad leaders during trials and experts made ratings afterward. Results revealed squad leaders had similar responses to probes, despite differences in combat experience. Analysis of probe frequency revealed different high priority SA elements and decisions for each scenario. The SA behavior and communication ratings revealed differences among squads, which trended with experience. Measures of SA were also consistent across the test scenario as a result of similar mission types and task difficulties. We discuss the implication of our findings for future research and theory within this area.

AB Heavy and abusive alcohol use is a major health problem facing military service members. We reviewed literature on alcohol intervention programs targeting military personnel to assess the methodological quality and effectiveness of the programs. Although the search yielded more than 42,000 citations, only 150 met initial screening criteria. Eighteen studies had sufficient evidence to meet secondary screening and of these only 10 studies were included in the review. These studies employed several types of interventions, but only 1 used a randomized controlled trial. Our findings indicate that there is greater need to assess intervention strategies, and there is a particular need for high-quality studies using randomized controlled trials with standardized assessment tools to improve the generalizability of the findings. We discuss the implications of our findings for future research in this area.

AB CD8+ T cells have been reported to play an important role in defense against B. abortus infection in mouse models. In the present report, we use CD8 knockout mice to further elucidate the role of these cells in protection from B. melitensis infection. Mice were immunized orally by administration of B. melitensis WR201, a purine auxotrophic attenuated vaccine strain, then challenged intranasally with B. melitensis 16M. In some experiments, persistence of WR201 in the spleens of CD8 knockout mice was slightly longer than that in the spleens of normal mice. However, development of anti-LPS serum antibody, antigen-induced production of gamma-interferon (IFN-gamma) by immune splenic lymphocytes, protection against intranasal challenge, and recovery of nonimmunized animals from intranasal challenge were similar between normal and knockout animals. Further, primary Brucella infection was not exacerbated in perforin knockout and Fas-deficient mice and these animals' anti-Brucella immune responses were indistinguishable from those of normal mice. These results indicate that CD8+ T cells do not play an essential role as either cytotoxic cells or IFN-gamma producers, yet they do participate in a specific immune response to immunization and challenge in this murine model of B. melitensis infection.

AB The increased availability of end use measurement studies allows for mechanistic and detailed approaches to estimating household water demand and conservation potential. This study simulates water use in a single-family residential neighborhood using end-water-use parameter probability distributions generated from Monte Carlo sampling. This model represents existing water use conditions in 2010 and is calibrated to 2006-2011 metered data. A two-stage mixed integer optimization model is then developed to estimate the least-cost combination of long- and short-term conservation actions for each household. This least-cost conservation model provides an estimate of the upper bound of reasonable conservation potential for varying pricing and rebate conditions. The models were adapted from previous work in Jordan and are applied to a neighborhood in San Ramon, California in the eastern San Francisco Bay Area. The existing conditions model produces seasonal use results very close to the metered data. The least-cost conservation model suggests clothes washer rebates are among most cost-effective rebate programs for indoor uses. Retrofit of faucets and toilets is also cost-effective and holds the highest potential for water savings from indoor uses. This mechanistic modeling approach can improve understanding of water demand and estimate cost-effectiveness of water conservation programs.

AB We experimentally demonstrate turbulence-free space-time quantum imaging. Quantum images of remote objects are produced with two sensors measuring at different space-time points under turbulent conditions. The quantum images generated move depending on the time delay between the two sensor measurements and the speed of a rotating ground glass that is part of a chaotic laser light source. For small delay times turbulence has virtually no adverse affect on the moving quantum images. The experimental setup and findings contribute to understanding the fundamentals of multi-photon quantum interference in complex media. Furthermore, the space-time memory demonstrated in our research provides important new pathways for investigating quantum imaging, quantum information storage and quantum computing. The turbulence-free space-time quantum imaging procedure greatly increases the information content of each photon measured. The moved quantum images are in fact new images that are stored in a space-time virtual memory process. The images are stored within the same quantum imaging data sets and thus quantum imaging can produce more information per photon measured than was previously realized.

AB A nine-month in situ bioremediation study was conducted in Makua Military Reservation (MMR) in Oahu, Hawaii (USA) to evaluate the potential of molasses to enhance biodegradation of royal demolition explosive (RDX) and high-melting explosive (HMX) contaminated soil below the root zone. MMR has been in operation since the 1940's resulting in subsurface contamination that in some locations exceeds USEPA preliminary remediation goals for these chemicals. A molasses-water mixture (1 : 40 dilution) was applied to a treatment plot and clean water was applied to a control plot via seven flood irrigation events. Pore water samples were collected from 12 lysimeters installed at different depths in 3 boreholes in each test plot. The difference in mean concentrations of RDX in pore water samples from the two test plots was very highly significant (p < 0.001). The concentrations differences with depth were also very highly significant (p < 0.001) and degradation was greatly enhanced at depths from 5 to 13.5 ft. biodegradation was modeled as first order and the rate constant was 0.063 per day at 5 ft and decreased to 0.023 per day at 11 ft to 13.5 ft depth. Enhanced biodegradation of HMX was also observed in molasses treated plot samples but only at a depth of 5 ft. The difference in mean TOC concentration (surrogate for molasses) was highly significant with depth (p = 0.003) and very highly significant with treatment (p < 0.001). Mean total nitrogen concentrations also differed significantly with treatment (p < 0.001) and depth (p = 0.059). The molasses water mixture had a similar infiltration rate to that of plain water (average 4.12 ft per day) and reached the deepest sensor (31 ft) within 5 days of application. Most of the molasses was consumed by soil microorganisms by about 13.5 feet below ground surface and treatment of deeper depths may require greater molasses concentrations and/or more frequent flood irrigation. Use of the bioremediation method described herein could allow the sustainable use of live fire training ranges by enhancing biodegradation of explosives in situ and preventing them from migrating to through the vadose zone to underlying ground water and off-site.

AB Mercury-specific diffusive gradient in thin films (DGTs) were used in laboratory microcosms as a biomonitoring tool to assess the lability of mercury (Hg) total and monomethylmercury Hg (MeHg), and to develop a relationship between chemical lability and bioavailability in estuarine sediments. Time-series deployment of DGTs in sediments showed that sediment-bound MeHg is more labile than sediment-bound inorganic Hg. In subsequent experiments, DGTs were deployed simultaneously with three benthic macroinvertebrates (the estuarine amphipod, Leptocheirus plumulosus; the estuarine polychaete, Nereis virens; and the marine clam, Macoma nasuta) in sediments for up to 55 days. All organisms and their co-deployed DGTs exhibited an initial period of rapid Hg uptake followed by slower uptake reaching apparent steady state. Strong correlative relationships were generally observed between paddle-type DGTs and macroinvertebrate tissue data (r(2) between 0.57 and 0.97). Further, %MeHg: Total Hg ratios for M. nasuta and N. virens (38.5 +/- 12.2 and 19.2 +/- 5.2) were similar to their corresponding ratios for the DGTs (33.1 +/- 13.3 and 24.4 +/- 11.0), and they were significantly higher than the same ratios for sediment (2.9 +/- 0.3) and pore water (8.5 +/- 4.9). The %MeHg: Total Hg ratios for L. plumulosus (68.5 +/- 6.2) were significantly higher than those for the DGTs. This may be because the tissue and DGT data for this organism were not truly co-located as L. plumulosus burrows close to the sediment surface, and the DGTs sampled the sediment surface. Overall, our results suggest that for benthic macroinvertebrates in estuarine sediments studied here, (a) sediment MeHg is more bioavailable than inorganic Hg, (b) sediment and pore-water concentration measurements are not good predictors for the extent of bioaccumulation of Hg species, and (c) DGTs are an effective biomonitoring tool for the assessment of bioavailability of Hg species.

AB Energy consumption by the US Army is becoming an increasingly important issue. The cost of providing fuel to Army outposts in deployed environments is particularly expensive due to numerous precautions required to defend fuel convoys from enemy attacks. This work is part of the Army's Construction Engineering Research Laboratory (CERL) efforts to reduce the amount of energy consumed by temporary barracks structures commonly referred to as "B-Huts". A prototype is being developed utilizing structurally insulated panels (SIP) and is referred to as a "SIP-Hut". This paper explores the benefits of incorporating photovoltaic (PV) panels into the SIP-Hut's power system. Powering a SIP-Hut is a unique challenge because SIP-Huts are typically located in remote and dangerous locations and, in addition, are temporary structures. A main thrust of this work was to examine if PV could be economically beneficial within this unique environment and short time span. However, the findings from this study can be applied to other remote locations where fossil fuels are not readily available. The SIP-Hut was modeled, solar resources estimated and analysis was performed using Hybrid Optimization Model for Electric Renewable (HOMER) software. Our analysis indicates that PV incorporation can have a significant positive impact on the amount of diesel fuel consumed and the overall cost of energy production.

AB As part of a year-long study for the Department of Systems Engineering at West Point, our Capstone project seeks to provide Tobyhanna Army Depot with a decision support tool that will quantify how changes in Depot Maintenance programs, to include the exploration of reset and recap maintenance for the AN/TPQ 37 Firefinder will affect the readiness, time, cost, reliability, and support costs of the Firefinder.
The AN/TPQ 37 Firefinder is a mobile radar system that provides detection of incoming artillery and rocket fire and tracks its movement in order to provide a location for counter-battery fire. This study is important because it incorporates an interdisciplinary approach to solving a complex problem using elements of industrial engineering, systems thinking, as well as modeling in producing a decision support tool that will allow Tobyhanna to make changes to their resources and service times in order to analyze these effects on turnaround times.
The problem will be solved in two phases. The first phase will be to model the current operations at Tobyhanna Army Depot by using the AnyLogic simulation tool. This will be done by analyzing maintenance data and using the AnyLogic simulation tool in order to model their current system turnaround of 180 days. Once this is complete and approved by Tobyhanna Army Depot, inputs in AnyLogic will be altered in order to show how these changes will impact service turnaround times.
So far, we have achieved an average turnaround time of 6 months with our current model. We have also succeeded in providing a decision support tool to Tobyhanna Army Depot that will allow them to alter their resource and labor constraints in order to accurately model what its impact on turnaround time will be.

AB Improvised Explosive Devices are the most dangerous threat to United States troops in Iraq and Afghanistan. Regardless of where troops deploy next, there is a strong likelihood of IED use in future conflicts. While great progress in analysis and exploitation of IED data has been made, the data is generally limited to historical attacks in current theaters of operation. The purpose of this analysis is to develop a tool that generates IED placement data based on statistically valid assumptions and distributions in any theater. These distributions can be used to train analysts prior to deployment to new environments. The research will generate data representing hypothetical IED attacks in a table structured like the CIDNE database. IED data from the CIDNE database will be used to develop distributions for each attack detailing IED location and type (type includes: command detonated, victim detonated, timer operated and radio controlled). Hypotheses will be tested using CIDNE data to determine some trends, including: seasonality, distance from road and location relative to terrain features. Results of these tests will shape the distributions used in the generation of synthetic datasets. The datasets will be generated based on road networks, terrain and population centers in Colorado, but shape files could be used from any region of the world. The results will generate various datasets that can be used for training analysts on IED attacks specific to any Operating Environment. This simulation will expose analysts to realistic data better preparing them for combat operations in their theater.

AB In a coalition context, data fusion involves combining of soft (e. g., field reports, intelligence reports) and hard (e. g., acoustic, imagery) sensory data such that the resulting output is better than what it would have been if the data are taken individually. However, due to the lack of explicit semantics attached with such data, it is difficult to automatically disseminate and put the right contextual data in the hands of the decision makers. In order to understand the data, explicit meaning needs to be added by means of categorizing and/or classifying the data in relationship to each other from base reference sources.
In this paper, we present a semantic framework that provides automated mechanisms to expose real-time raw data effectively by presenting appropriate information needed for a given situation so that an informed decision could be made effectively. The system utilizes controlled natural language capabilities provided by the ITA (International Technology Alliance) Controlled English (CE) toolkit to provide a human-friendly semantic representation of messages so that the messages can be directly processed in human/machine hybrid environments. The Real-time Semantic Enrichment (RTSE) service adds relevant contextual information to raw data streams from domain knowledge bases using declarative rules. The rules define how the added semantics and context information are derived and stored in a semantic knowledge base. The software framework exposes contextual information from a variety of hard and soft data sources in a fast, reliable manner so that an informed decision can be made using semantic queries in intelligent software systems.

machine; network emulation
AB The U.S Army Research Laboratory (ARL) has built a "Wireless Emulation Lab" to support research in wireless mobile networks. In our current experimentation environment, our researchers need the capability to run clusters of heterogeneous nodes to model emulated wireless tactical networks where each node could contain a different operating system, application set, and physical hardware. To complicate matters, most experiments require the researcher to have root privileges. Our previous solution of using a single shared cluster of statically deployed virtual machines did not sufficiently separate each user's experiment due to undesirable network crosstalk, thus only one experiment could be run at a time. In addition, the cluster did not make efficient use of our servers and physical networks. To address these concerns, we created the Dynamically Allocated Virtual Clustering management system (DAVC). This system leverages existing open-source software to create private clusters of nodes that are either virtual or physical machines. These clusters can be utilized for software development, experimentation, and integration with existing hardware and software. The system uses the Grid Engine job scheduler to efficiently allocate virtual machines to idle systems and networks. The system deploys stateless nodes via network booting. The system uses 802.1Q Virtual LANs (VLANs) to prevent experimentation crosstalk and to allow for complex, private networks eliminating the need to map each virtual machine to a specific switch port. The system monitors the health of the clusters and the underlying physical servers and it maintains cluster usage statistics for historical trends. Users can start private clusters of heterogeneous nodes with root privileges for the duration of the experiment. Users also control when to shutdown their clusters.

DE Airborne acoustic sensors; source localization; refraction corrections
AB Acoustic sensors are being employed on airborne platforms, such as Persistent Threat Detection System (PTDS) and Persistent Ground Surveillance System (PGSS), for source localization. Under certain atmospheric conditions, airborne sensors offer a distinct advantage over ground sensors. Among other factors, the performance of airborne sensors is affected by refraction of sound signals due to vertical gradients in temperature and wind velocity. A comprehensive experiment in source localization with an aerostat-mounted acoustic system was conducted in summer of 2010 at Yuma Proving Ground (YPG). Acoustic sources on the ground consisted of one-pound TNT denotations and small arms firings. The height of the aerostat was approximately 1 km above the ground. In this paper, horizontal, azimuthal, and elevation errors in source localization and their statistics are studied in detail. Initially, straight-line propagation is assumed; then refraction corrections are introduced to improve source localization and decrease the errors. The corrections are based on a recently developed theory [Ostashev, et. al, JASA 2008] which accounts for sound refraction due to vertical profiles of temperature and wind velocity. During the 2010 YPG field test, the vertical profiles were measured only up to a height of approximately 100 m. Therefore, the European Center for Medium-range Weather Forecasts (ECMWF) is used to generate the profiles for July of 2010.

ID MOBILITY MANAGEMENT
AB In this paper, we consider a problem related to service management and deployment in tactical military networks. Tactical networks are typically hybrid wireless networks in which there are both static and mobile nodes with several wireless interfaces, such as 802.11, 3G, satellite, etc. In tactical networks, performance degradation in services could prove fatal, so it must be diagnosed quickly. This degradation could be due to mobility or bottlenecks in capacity at network layer. We provide a cross-layer framework to detect and diagnose these causes of performance degradation as part of service management; it includes a monitoring model of services and a network model for hybrid wireless networks. In addition, we give a working example in tactical military networks to illustrate our framework. We provide an experimental setup to simulate our hybrid wireless tactical network scenario along with preliminary results.

DE network emulation; network simulation; experimentation; software stack
AB In 2006, the US Army Research Laboratory (ARL) and the UK Ministry of Defence (MoD) established a collaborative research alliance with academia and industry, named the International Technology Alliance in Network and Information Science (ITA) 1 to address fundamental issues concerning Network and Information Sciences. Research performed under the ITA was extended through a collaboration between ARL and IBM UK to characterize and define a software stack and tooling that will become the reference framework for network science experimentation. A key element to the success and validation of ITA theoretical research is experimentation in a controlled environment that can, as best as possible, emulate the real world conditions and context. Experimental validation in a network emulation environment contributes to the validation of theoretical concepts and algorithms, the investigation of more complex scenarios that span multiple research areas, exposing gaps in the theory that may need special attention, identifying additional areas where the research might focus and develop, and reproducible experimentation, which enables and facilitates the comparison of results from multiple executions of the same experiment. To accomplish these experimentation goals, the framework needs to foster the collaboration across multiple disciplines and facilitate the sharing of existing and new assets in a common emulation environment. The framework also needs to be extensible for the integration of new features, emulation models, monitoring, and integration with real, external assets that can be linked to any given experiment. This paper discusses the work resulting from the ARL/ IBM UK collaboration to build a framework to support experimentations and foster collaboration within and across different research groups.

AB RTI has demonstrated a novel photodiode technology based on IR-absorbing solution-processed PbS colloidal quantum dots (CQD) that can overcome the high cost, limited spectral response, and challenges in the reduction in pixel size associated with InGaAs focal plane arrays. The most significant advantage of the CQD technology is ease of fabrication. The devices can be fabricated directly onto the ROIC substrate at low temperatures compatible with CMOS, and arrays can be fabricated at wafer scale. Further, device performance is not expected to degrade significantly with reduced pixel size. We present results for upward-looking detectors fabricated on Si substrates with sensitivity from the UV to similar to 1.7 mu m, compare these results to InGaAs detectors, and present measurements of the CQD detectors temperature dependent dark current.

ID LOW-REFRACTIVE-INDEX; ANTIREFLECTION COATINGS; TECHNOLOGY
AB Electro-optical/infrared nanosensors are being developed for a variety of defense and commercial systems applications. One of the critical technologies that will enhance EO/IR sensor performance is the development of advanced antireflection coatings with both broadband and omnidirectional characteristics. In this paper, we review our latest work on high quality nanostructure-based antireflection structures, including recent efforts to deposit nanostructured antireflection coatings on large area substrates. Nanostructured antireflection coatings fabricated via oblique angle deposition are shown to enhance the optical transmission through transparent windows by minimizing broadband reflection losses to less than one percent, a substantial improvement over conventional thin-film antireflection coating technologies. Step-graded antireflection structures also exhibit excellent omnidirectional performance, and have recently been demonstrated on 6-inch diameter substrates.

AB InAs/GaSb type-II superlattices (T2-SLs) are of great interest as they provide a lot of band engineering flexibility. A wide variety of unipolar barrier structures have been investigated with this material system. In this report, we will present our recent work on the development of low noise long-wave infrared (LWIR) InAs/GaSb T2-SLs photodetectors. By adopting a so-called pBiBn design, the dark current of LWIR photodetectors is greatly suppressed. The LWIR pBiBn device has demonstrated a dark current density as low as 1.42x10(-5) A/cm(2) at -60 mV, and R(0)A of 5365 Omega cm(2) at 76 K. A peak detectivity at 7.8 mu m of 7.7x10(11) cmHz(1/2)W(-1) is obtained at 76 K. Further effort to reduce the operating bias is also reported. By refining the energy-band alignment, a 2-mu m-thick LWIR pBiBn device has demonstrated a single pass (no AR coating) quantum efficiency of 20% at 10 mu m under zero-bias at 77 K. We have recently extended our efforts to further reduce the dark current by using an interband cascade (IC) photodetector structure. Some further details about the device operation and results will be discussed.

AB We report a new concept for making poly(ethylene oxide) (PEO) based composite gel polymer electrolyte (CGPE) lithium batteries by demonstrating the fabrication of a lithium/sulfur (Li/S) cell, in which the CGPE is in situ formed by gelling a 50PEO-50SiO(2) (wt) composite membrane with a gel-forming liquid electrolyte. The composite membrane can be either coated onto the sulfur cathode to form an electrode-supporting electrode-membrane-assemble (EMA) or cast onto a Teflon substrate to form a freestanding membrane. Attributed to the presence of a large amount of inorganic SiO2 filler, the membrane can instantly absorb and retain various types of electrolyte solvents and ionic liquids without shrinkage. Using a gel-forming liquid electrolyte, the CGPE Li/S cell can be facilely prepared by heating an electrolyte-activated cell. In this paper, we demonstrate the preparation of a freestanding and highly flexible 50PEO-50SiO(2) composite membrane, and discuss the electrochemical characteristics of its resulting CGPE and the CGPE Li/S cell.

AB Higher energy density batteries are desired, especially for mobile electronic devices. Lithium metal anodes are a possible route to achieving high energy and power density due to their light weight compared to current graphite anodes. However, whisker growth during lithium electrodeposition (i.e. charging) represents a serious safety and efficiency concern for both lithium metal batteries and overcharging of graphite anodes in lithium-ion batteries. The initial morphology of deposited lithium nuclei can have a significant impact on the bulk material deposited. The nucleation of lithium metal from an organic ethylene carbonate: dimethyl carbonate (EC:DMC) and an ionic liquid (trimethylbutylammonium bis(triflouromethanesulfonyl)imide) electrolyte has been studied. Whisker extrusion and tip-based dendrite growth was observed ex-situ, and confirmed by in-situ optical microscopy experiments. The nucleation of a non-dendritic sodium co-deposit is also discussed. A model based on nuclei geometry is provided which gives insight into the deposition rate at constant overpotential. (C) 2013 The Electrochemical Society. All rights reserved.

AB Anion exchange membranes (AEMs) are being developed for potential use in fuel cell systems which include portable power applications. In a fuel cell, these membranes transport hydroxide ions from the cathode to the anode. If carbon dioxide is present, carbonate and bicarbonate ions can form, displacing the hydroxide ions. Among the challenges this presents, the carbonate and bicarbonate are less mobile than the hydroxide and therefore the ionic conductivity of the membrane suffers. A procedure is outlined to take data from a permeation based water flux experiment and determine diffusion coefficients and the ionic conductivity of the membrane. The water-membrane diffusion coefficients can be measured from a water flux experiment. Using principles from kinetic theory, the water-membrane diffusion coefficient can be converted to an appropriate ion-membrane diffusion coefficient. Finally, an equation derived from the dusty fluid model can be used to calculate the ionic conductivity of the membrane in different counter ion forms. The calculated ionic conductivities have been shown to agree well with reported values for proton and anion exchange membranes. (C) 2013 The Electrochemical Society. All rights reserved.

DE Information Fusion; Trust; Uncertainty; Description Logics
AB A limitation of standard Description Logics is its inability to reason with uncertain and vague knowledge. Although probabilistic and fuzzy extensions of DLs exist, which provide an explicit representation of uncertainty, they do not provide an explicit means for reasoning about second order uncertainty. Dempster-Shafer theory of evidence (DST) overcomes this weakness and provides means to fuse and reason about uncertain information. In this paper, we combine DL-Lite with DST to allow scalable reasoning over uncertain semantic knowledge bases. Furthermore, our formalism allows for the detection of conflicts between the fused information and domain constraints. Finally, we propose methods to resolve such conflicts through trust revision by exploiting evidence regarding the information sources. The effectiveness of the proposed approaches is shown through simulations under various settings.

AB This paper studies the relationship between trust and Situation Awareness (SA) in a 3-Player Iterated Diner's Dilemma game. We ran an experiment in which 24 participants each played against two computer opponents for six blocks of gameplay, with different opponent strategies in each block. Based on SA theory and design principles, we developed three different user interfaces, each supporting a specific SA Level. Each SA Level is inclusive of components from the previous level(s). We assess several trust-related metrics during the study, including percentage of cooperation over time and subjective level of self-reported trust towards the opponents, and analyze the interdependencies of trust, SA, and opponent strategy. Results from the experiment reveal highest levels of cooperation at SA Level 1 overall, and a higher level of cooperation for the group of cooperation-encouraging opponent strategies at SA Level 1 and 2 compared to cooperation-discouraging strategies. There is also a positive relationship between self-reported trust in the opponents and cooperation behavior for these strategies, but this relationship was not present in the cooperation-discouraging group. These results show that participants do respond to strategy type in terms of behavior, and that cooperation level is an indicator of the trust that participants place in the opponent players when cooperation emerges.

ID FACE RECOGNITION; IMAGES
AB A multistage algorithm suite is proposed for a specific target detection/verification scenario, where a visible/near infrared hyperspectral (HS) sample is assumed to be available as the only cue from a reference image frame. The target is a suspicious dismount. The suite first applies a biometric based human skin detector to focus the attention of the search. Using as reference all of the bands in the spectral cue, the suite follows with a Bayesian Lasso inference stage designed to isolate pixels representing the specific material type cued by the user and worn by the human target (e.g., hat, jacket). In essence, the search focuses on testing material types near skin pixels. The third stage imposes an additional constraint through RGB color quantization and distance metric checking, limiting even further the search for material types in the scene having visible color similar to the target visible color. Using the proposed cumulative evidence strategy produced some encouraging range-invariant results on real HS imagery, dramatically reducing to zero the false alarm rate on the example dataset. These results were in contrast to the results independently produced by each one of the suite's stages, as the spatial areas of each stage's high false alarm outcome were mutually exclusive in the imagery. These conclusions also apply to results produced by other standard methods, in particular the kernel SVDD (support vector data description) and matched filter, as shown in the paper.

AB This paper presents a preliminary study of the effects residual plastic strains have on Lamb wave velocities and time of flight measurements. The potential application of this research is non-destructive evaluation and structural health monitoring, particularly reconstructing plastic strain fields. The finite deformation of a semi-infinite plate due to residual plastic strain is used to accommodate the changes in plate thickness and elongation. The results show that the S-0 mode exhibits significant variations in group velocity in the highly dispersive regions, as much as a 2% increase in velocity with a 1% plastic strain. However, for time of flight measurements, the plate elongation had an order of magnitude effect rather than showing velocity changes. By exploiting time delay measurements, it may be possible to use wave speed measurements to determine plastic zones through Lamb-like waves.

TI Graphene-Based and Other Electrochemical Double Layer Capacitors for
Energy Harvesting Systems
SO ECS JOURNAL OF SOLID STATE SCIENCE AND TECHNOLOGY

DT Article
AB A piezoelectric energy harvesting system that generates energy from the oscillation of a mass-spring and stores the energy on a capacitor is being developed for replacing batteries in some applications. Typically, this energy is stored in an electrolytic capacitor. Here, we explore a number of electrolytic- and electrochemical double layer capacitors (EDLCs, aka supercapacitors), including a graphene-array-based EDLC, for storing this energy. EDLCs are of interest because they are potentially smaller, lighter, and more reliable than conventional capacitors and batteries. One issue with using EDLCs in this application is that the piezoelectric voltage output can greatly exceed the EDLC electrolyte breakdown voltage of a single cell, and the oscillation frequency greatly exceeds the frequency response of most commercial EDLCs. We find that electrolyte breakdown is not a serious limitation with transient overvoltage, as electrolyte breakdown is kinetically limited, and further, any breakdown is self-healing. In this study, we report results from capacitors of different sizes and response times, and find that capacitors of similar size store similar quantities of energy, with faster capacitors charging more quickly.

AB A meshed carbon nanotube thread patch antenna is proposed and analyzed through full-wave electromagnetic simulation. The effects of thread spacing and of fabricating the feedline and ground-plane layers from meshed thread are explored. Results indicate that minimal impact on antenna radiation efficiency and usable bandwidth is achieved with a thread spacing of d <= lambda/30. A minor center frequency shift and reduction in realized gain and bandwidth occurs when the thread spacing is increased. When the feedline and/or ground plane is constructed from meshed carbon nanotube thread material, the realized gain is significantly reduced. Improvements to carbon nanotube thread conductivity should mitigate this reduction in realized gain.

AB This paper provides a demand based balance of flow manpower model premised in mathematical programming to provide insight into the potential futures of the Afghan Education System. Over the previous three decades, torn from multiple wars and an intolerant governing regime, the education system in Afghanistan has been decimated. Over the past 10 years Afghanistan and the international community have dedicated a substantial amount of resources to educate the youth of Afghanistan. By forecasting student demand we are able to determine points of friction in the teacher production policy regarding grade level, gender, and province across a medium-term time horizon. We modify the model to provide sensitivity analysis to inform policies. Examples of such policies are accounting for the length of teacher training programs and encouragement of inter-provincial teacher moves. By later applying a stochastic optimization model potential outcomes regarding changes in teacher retention attributed to policy decisions, incentives to teach, or security concerns are highlighted. This model was developed in support of the validation of a large scale simulation regarding the same subject.

AB Visual sensing is an attractive method to allow small, palm-sized flying vehicles to navigate complex environments without collisions. Visual processing for unmanned vehicles, however, is typically computationally intense. Insects are able to extract structural information about the environment by appropriate control of self-motion and efficient processing of the visual field. This paper presents a methodology that attempts to capture the insect's ability to do this by constructing a nonlinear observer with provable stability via a Lyapunov analysis. Furthermore, the persistency of excitation condition for the observer illustrates the need for a zig-zagging flight style exhibited by certain insects.

AB Due to the costliness of destructive evaluation methods for assessing the aging and shelf-life of missile and rocket components, the identification of nondestructive evaluation methods has become increasingly important to the Army. Verifying that there is a sufficient concentration of stabilizer is a dependable indicator that the missile's double-based solid propellant is viable. The research outlined in this paper summarizes the Army Aviation and Missile Research, Development, & Engineering Center's (AMRDEC's) comparative use of nanoporous membranes, carbon nanotubes, and optical spectroscopic configured sensing techniques for detecting degradation in rocket motor propellant. The first sensing technique utilizes a gas collecting chamber consisting of nanoporous structures that trap the smaller solid propellant particles for measurement by a gas analysis device. In collaboration with NASA-Ames, sensing methods are developed that utilize functionalized single-walled carbon nanotubes as the key sensing element. The optical spectroscopic sensing method is based on a unique light collecting optical fiber system designed to detect the concentration of the propellant stabilizer. Experimental setups, laboratory results, and overall effectiveness of each technique are presented in this paper. Expectations are for the three sensing mechanisms to provide nondestructive evaluation methods that will offer cost-savings and improved weaponry health monitoring.

AB This paper presents the one soliton modulated cosine solution to the Biswas-Milovic equation with log law nonlinearity. The approach is to use the ansatz method to obtain relations for the velocity of the soliton or spatial Gausson with equations for dispersion and the amplitude of the soliton. It turns out that the modulated beam requires an additional periodic relation for the one soliton solution existence. Published by Elsevier GmbH.

AB In this work the performance of bottom gate thin film transistors (TFTs) with transparent amorphous gallium tin zinc oxide (GSZO) active layers fabricated by radio frequency sputter deposition using a single GSZO target on SiO2/Si wafers will be presented. Trap density and its energetic distribution, and oxygen chemisorption were found to play a critical role in determining the operational characteristics of the device, all of which can be controlled by the oxygen incorporation and substrate temperature during deposition, along with the post-deposition annealing. In addition device instability, with respect to the electrical stress and optical illumination, can be suppressed by suitably tailoring these parameters. TFTs exhibiting a drain current (ID) of 10(-6) A and on/off current ratio (I-on/off) of 106 was achieved. A stable TFT has been achieved under electrical stress for 2% oxygen flow exhibiting.Delta V-T as low as similar to 0.5 V for 3hr stress under a gate bias of 1.2 and 12 V, with good optical stability.

AB Recently, the US Army developed a prototype shortwave infrared (SWIR) multispectral polarized scene projector (MPSP) system. This system is capable of projecting single spectral images as well as videos with full polarization content from 850 to 1650 nm with variable spectral bandwidth. The bandwidth can vary between 12 and 100 nm. A multistage liquid crystal tunable filter is used to tune the wavelength of light with desired bandwidth and three reflective 512x512 liquid crystal on silicon (LCoS) spatial light modulators (SLMs) with 37.5 mu m pixel pitch are used to project an image with all Stokes parameters. This scene projector is intended to characterize hardware-in-the loop spectral and polarization performance of spectropolarimetric imagers operating in the SWIR region. We used this projector to characterize a SWIR hyperspectral imager with a single polarization based on an acousto-optic tunable filter (AOTF). Here, we will briefly describe the scene projector and the hyperspectral imager, discuss the experimental setup and present the results of our characterization.

AB Currently almost all antibiotics are administered by the intravenous route. Since several systems and situations require more efficient methods of administration, investigation and experimentation in drug design has produced local treatment modalities. Administration of antibiotics in aerosol form is one of the treatment methods of increasing interest. As the field of drug nanotechnology grows, new molecules have been produced and combined with aerosol production systems. In the current review, we discuss the efficiency of aerosol antibiotic studies along with aerosol production systems. The different parts of the aerosol antibiotic methodology are presented. Additionally, information regarding the drug molecules used is presented and future applications of this method are discussed.

ID V-SEMICONDUCTORS; LIFETIME
AB Time-resolved photoluminescence (TRPL) is used to study the minority carrier lifetime in type-II superlattice (T2SL) infrared detector materials to investigate the recombination mechanisms, trap states and transport properties that currently limit their performance. Measurements of carrier lifetime have shown that InAs/Ga1-xInxSb T2SLs are dominated by non-radiative Shockley-Read-Hall (SRH) recombination, resulting in short minority carrier lifetimes (10's of nanoseconds at 77 K). A trap energy of similar to 60 meV above the valence band is identified in mid-wavelength infrared n-type InAs/Ga1-xInxSb T2SLs, where trap saturation (non-exponential decay) is observed under high injection levels due to a significantly faster hole capture rate than electron capture rate. Lifetime measurements in "Ga-free" InAs/InAs1-xSbx T2SLs exhibit an order-of-magnitude increase in lifetime (100's of nanoseconds at 77 K) with contributions from both radiative and non-radiative recombination. This improvement is attributed to the reduction of non-radiative recombination centers from the superlattice with the elimination of Ga and suggests that the SRH trap(s) limiting the carrier lifetime of InAs/Ga1-xInxSb T2SLs is native to the Ga1-xInxSb layer. Additionally, radiative recombination is observed in an InAs/GaSb T2SL using a sub-bandgap CW laser to saturate the SRH recombination centers, yielding a radiative lifetime of similar to 140 ns at 77 K. Since carrier transport is a concern in Ga-free T2SLs, it is investigated by studying samples grown with and without barriers (to contain injected carriers to the absorber region). It is determined that carrier transport is poor in InAs/InAs1-xSbx T2SLs because negligible differences are observed in the carrier lifetime.

AB Sensor technologies are undergoing revolutionary advances, as seen in the rapid growth of multispectral methodologies. Increases in spatial, spectral, and temporal resolution, and in breadth of spectral coverage, render feasible sensors that function with unprecedented performance. A system was developed that addresses many of the key hardware requirements for a practical dual-band multispectral acquisition system, including wide field of view and spectral/temporal shift between dual bands. The system was designed using a novel dichroic beam splitter and dual band-pass filter configuration that creates two side-by-side images of a scene on a single sensor. A high-speed CMOS sensor was used to simultaneously capture data from the entire scene in both spectral bands using a short focal-length lens that provided a wide field-of-view. The beam-splitter components were arranged such that the two images were maintained in optical alignment and real-time intra-band processing could be carried out using only simple arithmetic on the image halves. An experiment related to limitations of the system to address multispectral detection requirements was performed. This characterized the system's low spectral variation across its wide field of view. This paper provides lessons learned on the general limitation of key hardware components required for multispectral muzzle flash detection, using the system as a hardware example combined with simulated multispectral muzzle flash and background signatures.

AB High-order cognitive functions require the integration of information across functionally related modules. This relationship suggests that cognitive ability is related to the efficiency and processing speed of basic integrative function. In order to examine individual differences for this relationship, we compared standardized tests of intelligence to visual perceptual grouping abilities, which represents a basic process of integration. Sixty participants discriminated perceived grouping of dot patterns based upon similarity in luminance. Psychophysical measurements were made of the functional limits and processing speed of grouping. We assessed cognitive abilities with the Wechsler Abbreviated Scale of Intelligence (WASI) and found that measures of grouping efficiency as well as speed varied considerably across subjects, indicating substantial individual differences at this relatively early level of visual processing. Faster grouping speed was associated with higher scores on all WASI subtests, whereas grouping ability, when not restricted by time, was associated only with the performance IQ components. These results demonstrate an association between a basic integrative function, in which cognitive and motoric factors were minimized, with measures of high-order cognition, which include both verbal and spatial cognitive components.

AB In recent years, the bio-refining industry has developed a number of cyclic molecules with unique attributes derived from renewable carbohydrate feedstocks. Isosorbide is one such compound that has a distinctive fused bicyclic ring system that provides a scaffold for the development of novel bio-based resin systems. We synthesized isosorbide-methacrylate (IM) by the direct esterification of isosorbide using highly reactive species such as methacryloyl chloride or methacrylic anhydride and a base catalyst. IM is a low viscosity (157 cP) cross-linking resin that free radically reacts to form a thermoset polymer with extent of cure at 85%. The resulting polymer has a T-g greater than 240 degrees C and main degradation temperature of similar to 400 degrees C. Mechanical test results showed that IM had a modulus of similar to 4 GPa and strength of 85 MPa. These thermal and mechanical properties show that IM has a significantly higher temperature operating window than any known vinyl ester resin and has similar performance to expensive high temperature epoxy resins. As such, this material has good potential for use in composite applications where a moderate to high temperature free radical cured polymer matrix is needed.

AB We apply the equivalence particle principle to several nonlinear Schrodinger equations (NLSEs) that model the propagation of a spatial beam with logarithmic law nonlinearity. Using this principle, expressions for acceleration, spatial frequency, spatial period and other variables for a spatial soliton can be derived from the solution of the homogenous NLSE with logarithmic law nonlinearity. These results agree well with numerical simulations of the perturbed NLSE. We show that if the expression of the acceleration is bounded this means the spatial soliton propagates with a swing effect.

AB The micro- and nano-mechanical properties of a CoCrMo medical implant alloy and a novel micro-textured carbide-coated CoCrMo alloy (MTCC) surface hardness and roughness were examined using micro- and nano-indentation and surface profilometry. The MTCC surfaces may be a successful alternative bearing material for artificial joints. Understanding the micro- and nano-mechanical, material properties and surface morphology of the MTCC-CoCrMo surface are important for designing wear resistant artificial joints. The micro- textured carbide surfaces were created using a microwave plasma assisted chemical vapor deposition reaction (MPCVD). Micro- and nano-mechanical properties, volumetric wear properties, and surface morphology were measured and used to determine the performance of the conventional CoCrMo alloy and MTCC surfaces (processed for either 2 or 4 hours) in static environments and under severe wear conditions. The hardness and surface parameters of the 4h MTCC surfaces were always greater than the 2h MTCC and CoCrMo alloy surfaces. The mirco- and nano-mechanical properties changed for the CoCrMo alloy, 2h, and 4h MTCC surfaces after, in contrast to before, wear testing. This indicates that the wear mechanisms affect the micro- and nano-mechanical results. Overall, the 4h MTCC surfaces had greater wear resistance than the 2h MTCC or CoCrMo alloy surfaces.

ID EDUCATION; CONFIDENCE
AB Objective. To compare second- and third-year pharmacy students' competence, attitudes, and self-confidence in providing diabetes care before and after completing a hand-on diabetes training program and to determine if the program had an impact on students' attitude and self-confidence based on their year in the curriculum.
Design. The program included classroom lectures and hands-on learning sessions in 5 facets of diabetes care. Pre- and post-test instruments measured students' competence, attitudes, and confidence in diabetes care.
Assessment. Students' competence and the mean overall confidence score significantly improved after completing the program, while mean overall attitude score did not. Third-year students had significantly higher confidence scores than did second-year students on both pre- and post-program tests. No significant difference was found for attitude scores between second-and third-year students.
Conclusion. The hands-on learning program was an effective approach to training pharmacy students in diabetes care, improving both their competence and confidence.

ID POWDER PARTICLES; SUBSTRATE; ALUMINUM; DESIGN; NOZZLE
AB Magnesium alloys are widely used in aircraft and automotive components because of their inherent light weight compared to other engineering metals. However, premature corrosion is one of the challenges associated with magnesium. In the aerospace industry, many expensive castings cannot be reclaimed adequately because current methods are often inappropriate due to excessive porosity, oxidation and thermal damage. Cold spray is a solid-state coating process that uses a supersonic gas jet to accelerate small particles against a substrate to produce metal bonding by rapid plastic deformation of the impacting particles. Significantly, magnesium components can be repaired, restored and protected by cold spray deposition of pure aluminum which has thus already been specified by some aerospace users as a standard technique for magnesium repair. In this chapter, the state of the art of commercial cold spray technologies for magnesium repair will be discussed, as well as their advantages and limitations compared to traditional thermal processes.

STATISTICS
AB We report the synthesis and characterisation of mixed-metal binuclear ruthenium(II)-vanadium(IV) complexes, which were used as potential photodynamic therapeutic agents for melanoma cell growth inhibition. The novel complexes, [Ru(pbt)(2)(phen(2)DTT)](PF6)(2)center dot 1.5H(2)O 1 (where phen(2)DTT = 1,4-bis(1,10-phenanthrolin-5-ylsulfanyl)butane-2,3-diol and pbt = 2-(2'-pyridyl)benzothiazole) and [Ru(pbt)(2)(tpphz)](PF6)(2)center dot 3H(2)O 2 (where tpphz = tetrapyrido[3,2-a:2',3'-c:3 '',2 ''-h:2 ''',3 ''';-j]phenazine) were synthesised and characterised. Compound 1 was reacted with [VO(sal-L-tryp)(H2O)] (where sal-L-tryp = N-salicylidene-L-tryptophanate) to produce [Ru(pbt)(2)(phen(2)DTT)VO(sal-L-tryp)](PF6)(2)center dot 5H(2)O 4; while [VO(sal-L-tryp)(H2O)] was reacted with compound 2 to produce [Ru(pbt)(2)(tpphz)VO(sal-L-tryp)](PF6)(2)center dot 6H(2)O 3. All complexes were characterised by elemental analysis, HRMS, ESI MS, UV-visible absorption, ESR spectroscopy, and cyclic voltammetry, where appropriate. In vitro cell toxicity studies (with the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) colorimetric assay) via dark and light reaction conditions were carried out with sodium diaqua-4,4',4 '',4 ''' tetrasulfophthalocyaninecobaltate(II) (Na-4[Co(tspc)(H2O)(2)]), [VO(sal-L-tryp)(phen)]center dot H2O, and the chloride salts of complexes 3 and 4. Such studies involved A431, human epidermoid carcinoma cells; human amelanotic malignant melanoma cells; and HFF, non-cancerous human skin fibroblast cells. Both chloride salts of complexes 3 and 4 were found to be more toxic to melanoma cells than to non-cancerous fibroblast cells, and preferentially led to apoptosis of the melanoma cells over non-cancerous skin cells. The anti-cancer property of the chloride salts of complexes 3 and 4 was further enhanced when treated cells were exposed to light, while no such effect was observed on non-cancerous skin fibroblast cells. ESR and V-51 NMR spectroscopic studies were also used to assess the stability of the chloride salts of complexes 3 and 4 in aqueous media at pH 7.19. This research illustrates the potential for using mixed-metal binuclear ruthenium(II)-vanadium(IV) complexes to fight skin cancer.

AB Optical mapping is a technique that produces an ordered restriction map of a bacterial or eukaryotic chromosome. We have developed a new method, the BOP method, to compare experimental optical maps with insilico optical maps of complete genomes to infer the presence/absence of short DNA sequences (bops) in each genome. The BOP method, as implemented by the Optical Mapping suite of four programs, circumvents the necessity of whole-genome multiple alignments and permits reliable strain typing and clustering on the basis of optical maps. We have applied the Optical Mapping Suite to 125 strains of Acinetobacter sp., including 11 completely sequenced genomes and 114 Acinetobacter complex from three US military hospitals. We found that optical mapping completely resolves all 125 strains. Signal to noise analysis showed that when the 125 strains were considered together almost 1/3 of the experimental fragments were misidentified. We found that the set of 125 genomes could be divided into three clusters, two of which included sequenced genomes. Signal to noise analysis after clustering showed that only 3.5% of the experimental restriction fragments were misidentified. Minimum spanning trees of the two clusters that included sequenced genomes are presented. The programs we have developed provide a more rigorous approach for analyzing optical map data than previously existed.

AB The U.S. Army Corps of Engineers (USACE) Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX) collected its first airborne coastal mapping data on the Great Lakes in 1995. Since then, the JALBTCX has collected nearly 5 billion elevation and depth measurements and created over 2000 geographic information system (GIS) products for the shorelines of the Great Lakes. With improvements in airborne coastal mapping technology and the introduction of regional management for the USACE, surveys expanded into the regional scale, multi-sensor National Coastal Mapping Program (NCMP). The NCMP was initiated in 2004 to produce recurrent, regional, high-resolution light detection and ranging (lidar) elevation data and hyperspectral and aerial imagery to support regional sediment management, regulatory functions, flood damage reduction, asset management, emergency operations, and environmental stewardship. The JALBTCX is a collaboration among the USACE, the U.S. Naval Oceanographic Office (NAVOCEANO), and the National Oceanic and Atmospheric Administration (NOAA). The partners have worked together on airborne coastal mapping and charting since the late 1980s with the goal of advancing airborne lidar bathymetry and associated technologies. The collaboration has fielded three generations of airborne sensors and has transferred this technology to the commercial sector, supporting an expanding market for bathymetric lidar. The purpose of this paper is to provide an overview of the history of USACE survey efforts in the Great Lakes (1995-2012), an in-depth review of the resulting imagery and lidar data products, and new information product developments and applications to support environmental and coastal engineering throughout the Great Lakes region.

AB LiDAR (light detection and ranging) data can be used to create fine digital elevation and bathymetric models (DEMs). Here we examine natural coastal erosion in Grand Traverse Bay, Michigan, a part of Keweenaw Bay in Lake Superior, and discuss how a variety of geological features (submersed river bed and channels associated with the Houghton Low; Nipissing dunes) interact with long-term sediment accumulation patterns. The geological features also modify migrating tailings from a legacy mining site. The combination of LiDAR derived images and aerial photographs allowed us to reconstruct the historical movement of tailings along the coastline. A total of 22.8 million metric tonnes (Mt) of stamp sand were discharged into the coastal environment off Gay, MI. Over a span of 80 years, beaches to the southwest of Gay have progressively received 7.0 Mt (30.7%) of the mass eroded from the original pile, whereas 11.1 Mt (48.7%) have moved into the bay. The total amount accumulated along the beaches now greatly exceeds the mass remaining on the original tailings pile (3.7 Mt; 16.2%). Bathymetric differences between two LiDAR surveys (2008 and 2010) were also used to estimate the mass, and to track the movement of migrating underwater stamp sand bars. These bars are moving southwesterly towards Buffalo Reef, creating a threat to the lake trout and lake whitefish breeding ground. (C) 2013 International Association for Great Lakes Research.

TI Energy Dissipation and the High-Strain Rate Dynamic Response of
Vertically Aligned Carbon Nanotube Ensembles Grown on Silicon Wafer
Substrate
SO JOURNAL OF NANOMATERIALS
LA English
DT Article
AB The dynamic mechanical behavior and high-strain rate response characteristics of a functionally graded material (FGM) system consisting of vertically aligned carbon nanotube ensembles grown on silicon wafer substrate (VACNT-Si) are presented. Flexural rigidity (storage modulus) and loss factor (damping) were measured with a dynamic mechanical analyzer in an oscillatory three-point bending mode. It was found that the functionally graded VACNT-Si exhibited significantly higher damping without sacrificing flexural rigidity. A Split-Hopkinson pressure bar (SHPB) was used for determining the system response under high-strain rate compressive loading. Combination of a soft and flexible VACNT forest layer over the hard silicon substrate presented novel challenges for SHPB testing. It was observed that VACNT-Si specimens showed a large increase in the specific energy absorption over a pure Si wafer.

AB Asystematic study of electrolytes has been conducted to explore howsolution structure dictates electrolyte properties. Specifically, the transport properties (viscosity, conductivity and molar conductivity) of acetonitrile-lithium salt mixtures, (AN)(n)-LiX, are reported for electrolytes with LiPF6, LiTFSI (i.e., LiN(SO2CF3)(2)), LiClO4, LiBF4 and LiCF3CO2. These salts have widely varying ion solvation/ionic association behavior which is directly reflected in the transport properties of the AN solutions. Information about the solution structure has been utilized, in concert with molecular dynamic (MD) simulations, to provide mechanistic explanations for the variability noted in the transport properties of the electrolyte mixtures.

AB A mixture of iron (II) phthalocyanine and polyacrylonitrile (PAN) was electrospun into fibers and pyrolyzed to form Fe-containing carbon fibers (Fe-PAN). Subsequent atomic layer deposition (ALD) coated the fibers with TiOy deposits (TiOy-Fe-PAN). Scanning transmission electron microscopy equipped with energy dispersive spectroscopy (STEM-EDS) detected C, Fe, and Ti across the diameter of the fiber, and X-ray photoelectron spectroscopy (XPS) revealed Fe(III) and CNx species present. After the ALD process, XPS revealed TiOy species on the Fe-PAN fibers, and heat-treating the TiOy-Fe-PAN samples created TiNxOy and TiNx species. Heat-treating Fe-PAN and TiOy-Fe-PAN samples resulted in a slight decrease in the Fe wt.% but affected an increase in the oxygen reduction reaction (ORR) activity in 0.5M H2SO4 at room temperature compared to the samples not heat treated. Moreover, the presence of Ti species decreased the production of H2O2 and increased the mass activity of the ORR on fibers subjected to cyclic potential excursions relative to samples without Ti species.

AB We report on the synthesis of a novel type of ultrathin hydrogel with remarkably high, fast and reversible swelling/shrinkage and sharp surface wettability transitions in response to pH changes. The poly(4-vinylpyridine) (PVP) hydrogels are produced by the selective cross-linking of PVP copolymer layers in PVP/poly(methacrylic acid) (PVP/PMAA) layer-by-layer (LbL) films assembled by a spin-assisted method on surfaces. These multilayer hydrogels exhibit drastic and reversible 10-fold swelling when pH is switched from neutral to acidic. Importantly, hydrogels at pH > 5 collapse to the thickness of dry films, evincing sharp hydrophilic-to-hydrophobic transitions. The swelling amplitude of these multilayer hydrogel coatings is controlled by varying cross-link densities within the hydrogel. Further, the pH-triggered swelling properties of PVP hydrogels are significantly affected by the multilayer assembly method. PVP films produced using the spin-assisted method experienced almost a 4-fold greater swelling enhancement over their conventionally "dipped" counterparts. Finally, PVP hydrogels dehydrated from basic and acidic solutions show drastically different surface morphology and wettability properties. The hydrogel contact angles vary from 70 degrees to 20 degrees for the films dried from neutral and acidic solutions, respectively. Our study provides better understanding of regulated volume and surface wettability transitions in polymer networks which is critical for developing novel materials for a wide variety of applications including sensing, transport regulation, and self-cleaning coatings.

AB The U.S. Army Research Laboratory (ARL) supports the development of classification, detection, tracking, and localization algorithms using multiple sensing modalities including acoustic, seismic, E-field, magnetic field, PIR, and visual and IR imaging. Multimodal sensors collect large amounts of data in support of algorithm development. The resulting large amount of data, and their associated high-performance computing needs, increases and challenges existing computing infrastructures. Purchasing computer power as a commodity using a Cloud service offers low-cost, pay-as-you-go pricing models, scalability, and elasticity that may provide solutions to develop and optimize algorithms without having to procure additional hardware and resources. This paper provides a detailed look at using a commercial cloud service provider, such as Amazon Web Services (AWS), to develop and deploy simple signal and image processing algorithms in a cloud and run the algorithms on a large set of data archived in the ARL Multimodal Signatures Database (MMSDB). Analytical results will provide performance comparisons with existing infrastructure. A discussion on using cloud computing with government data will discuss best security practices that exist within cloud services, such as AWS.

AB Field and laboratory measurements of Light Detection and Ranging (LIDAR) sensor interactions with dust have been performed for two types of common ground-based LIDAR sensors. A strong correlation (R-2 > 0.95) between the probability for a return from the dust and the optical depth of the dust was found in the analysis. Based on the experimental correlation, a probabilistic model for LIDAR interactions with dust was developed and verified in field experiments. Finally, the model was integrated into a high-fidelity ray-tracing simulation of LIDAR systems

ID FEATURE-EXTRACTION; HUMAN GAIT; MODEL
AB Wideband radar provides a significant improvement over traditional narrowband radars for micro-Doppler analysis because the high bandwidth can be used to separate many of the signals in range, allowing a simpler decomposition of the micro-Doppler signals. Recent wideband radar work has focused on micro-Doppler, but there is a point where the narrowband approach used to analyze the micro-Doppler signals breaks down. The effect is shown to be independent of frequency, but the error relative to the bandwidth is shown to be inversely proportional to the frequency and proportional to the velocity of the subject. This error can create a smearing effect in the observed Doppler if it is not corrected, leading to reduced signal-to-noise and the appearance of more diffuse targets in Doppler space. In range-space, wideband data can also break the subject into several range bins, affecting the observed signal to noise ratio. The possible applications of wideband micro-Doppler radar are also shown, including the separation of arm movement from human motion which implies that the arms are not encumbered.

AB This study investigates a lumped-parameter human body model which includes lower leg in seated posture within a quarter-car model for blast injury assessment simulation. To simulate the shock acceleration of the vehicle, mine blast analysis was conducted on a generic land vehicle crew compartment (sand box) structure. For the purpose of simulating human body dynamics with non-linear parameters, a physical model of a lumped-parameter human body within a quarter car model was implemented using multi-body dynamic simulation software. For implementing the control scheme, a skyhook algorithm was made to work with the multi-body dynamic model by running a co-simulation with the control scheme software plug-in. The injury criteria and tolerance levels for the biomechanical effects are discussed for each of the identified vulnerable body regions, such as the relative head displacement and the neck bending moment. The desired objective of this analytical model development is to study the performance of adaptive semi-active magnetorheological damper that can be used for vehicle-occupant protection technology enhancements to the seat design in a mine-resistant military vehicle.

AB Multiplex coherent anti-Stokes Raman spectroscopy (MCARS) is used to detect an explosive precursor material and two chemical warfare simulants. The spectral bandwidth of the femtosecond laser pulse used in these studies is sufficient to coherently and simultaneously drive all the vibrational modes in the molecule of interest. The research performed here demonstrates that MCARS has the capability to detect an explosive precursor (e. g., acetone) and hazardous materials, such as dimethyl methylphosphonate and 2-chloroethyl methyl sulfide (a sarin and a mustard gas chemical warfare simulant, respectively), with high specificity. Evidence shows that MCARS is capable of overcoming common the sensitivity limitations of spontaneous Raman scattering, thus allowing for the detection of the target material in milliseconds with standard USB spectrometers as opposed to seconds with intensified spectrometers. The exponential increase in the number of scattered photons suggests that the MCARS technique may be capable of overcoming range detection challenges common to spontaneous Raman scattering.

AB Reliable, robust, and portable technologies are needed for the rapid identification and detection of chemical, biological, and explosive (CBE) materials. A key to addressing the persistent threat to U. S. troops in the current war on terror is the rapid detection and identification of the precursor materials used in development of improvised explosive devices, homemade explosives, and bio-warfare agents. However, a universal methodology for detection and prevention of CBE materials in the use of these devices has proven difficult. Herein, we discuss our efforts towards the development of a modular, robust, inexpensive, pervasive, archival, and compact platform (android based smart phone) enabling the rapid detection of these materials.

AB The secreted proteins of the enterohemorrhagic and enteropathogenic E. coli (EHEC and EPEC) are the most common cause of hemorrhagic colitis, a bloody diarrhea with EHEC infection, which often can lead to life threatening hemolytic-uremic syndrome (HUS). We are employing a metaproteomic approach as an effective and complimentary technique to the current genomic based approaches. This metaproteomic approach will evaluate the secreted proteins associated with pathogenicity and utilize their signatures as differentiation biomarkers between EHEC and EPEC strains. The result showed that the identified tryptic peptides of the secreted proteins extracted from different EHEC and EPEC growths have difference in their amino acids sequences and could potentially utilized as biomarkers for the studied E. coli strains. Analysis of extract from EHEC O104:H4 resulted in identification of a multidrug efflux protein, which belongs to the family of fusion proteins that are responsible of cell transportation. Experimental peptides identified lies in the region of the HlyD haemolysin secretion protein-D that is responsible for transporting the haemolysin A toxin. Moreover, the taxonomic classification of EHEC O104:H4 showed closest match with E. coli E55989, which is in agreement with genomic sequencing studies that were done extensively on the mentioned strain. The taxonomic results showed strain level classification for the studied strains and distinctive separation among the strains. Comparative proteomic calculations showed separation between EHEC O157:H7 and O104:H4 in replicate samples using cluster analysis. There are no reported studies addressing the characterization of secreted proteins in various enhanced growth media and utilizing them as biomarkers for strain differentiation. The results of FY-2012 are promising to pursue further experimentation to statistically validate the results and to further explore the impact of environmental conditions on the nature of the secreted biomarkers in various E. coli strains that are of public health concerns in various sectors.

AB The research areas of tissue engineering and drug development have displayed increased interest in organ-on-a-chip studies, in which physiologically or pathologically relevant tissues can be engineered to test pharmaceutical candidates. Microfluidic technologies enable the control of the cellular microenvironment for these applications through the topography, size, and elastic properties of the microscale cell culture environment, while delivering nutrients and chemical cues to the cells through continuous media perfusion. Traditional materials used in the fabrication of microfluidic devices, such as poly(dimethylsiloxane) (PDMS), offer high fidelity and high feature resolution, but do not facilitate cell attachment. To overcome this challenge, we have developed a method for coating microfluidic channels inside a closed PDMS device with a cell-compatible hydrogel layer. We have synthesized photocrosslinkable gelatin and tropoelastin-based hydrogel solutions that were used to coat the surfaces under continuous flow inside 50 mm wide, straight microfluidic channels to generate a hydrogel layer on the channel walls. Our observation of primary cardiomyocytes seeded on these hydrogel layers showed preferred attachment as well as higher spontaneous beating rates on tropoelastin coatings compared to gelatin. In addition, cellular attachment, alignment and beating were stronger on 5% (w/v) than on 10% (w/v) hydrogel-coated channels. Our results demonstrate that cardiomyocytes respond favorably to the elastic, soft tropoelastin culture substrates, indicating that tropoelastin-based hydrogels may be a suitable coating choice for some organ-on-a-chip applications. We anticipate that the proposed hydrogel coating method and tropoelastin as a cell culture substrate may be useful for the generation of elastic tissues, e.g. blood vessels, using microfluidic approaches.

AB A Finite Element model has been developed for a Pratt truss railroad bridge located at Ft. Leonard Wood, MO. This model was used to investigate the vibration responses of a bridge under vehicle loading. Modeling results have been obtained for a single axle with two wheels traversing the bridge at different speeds. The current model does not include the effects of vehicle suspension. Superposition of multiple axles has been used to represent a locomotive transiting the bridge. The output of the vibration response was used as an input to an acoustic FE model to determine which vibrational modes radiate infrasound. The vibration and acoustic models of the railroad bridge will be reviewed, and results from the analysis will be presented. Measurements from an accelerometer mounted on the bridge agree reasonably well with model results. Infrasound could potentially be used to remotely provide information on the capacity and number of the vehicles traversing the bridge and to monitor the bridge for significant structural damage.

AB Cadence analysis has been the main focus for discriminating between the seismic signatures of people and animals. However, cadence analysis fails when multiple targets are generating the signatures. We analyze the mechanism of human walking and the signature generated by a human walker, and compare it with the signature generated by a quadruped. We develop Fourier-based analysis to differentiate the human signatures from the animal signatures. We extract a set of basis vectors to represent the human and animal signatures using non-negative matrix factorization, and use them to separate and classify both the targets. Grazing animals such as deer, cows, etc., often produce sporadic signals as they move around from patch to patch of grass and one must characterize them so as to differentiate their signatures from signatures generated by a horse steadily walking along a path. These differences in the signatures are used in developing a robust algorithm to distinguish the signatures of animals from humans. The algorithm is tested on real data collected in a remote area.

AB The mechanical response of p-phenylene terephthalamide (PPTA) single fibers when subjected to uniaxial compression is investigated computationally using coarse-grained molecular statics/dynamics methods. In order to construct the coarse-grained PPTA model (specifically, in order to define the nature of the coarse-grained particles/beads and to parameterize various components of the bead/bead force-field functions), the results of an all-atom molecular-level computational investigation are used. In addition, the microstructure/topology of the fiber core, consisting of a number of coaxial crystalline fibrils, is taken into account. Also, following our prior work, various PPTA crystallographic/topological defects are introduced into the model (at concentrations consistent with the prototypical PPTA synthesis/processing conditions). The analysis carried out clearly revealed (a) formation of the kink bands during axial compression; (b) the role of defects in promoting the formation of kink bands; (c) the stimulating effects of some defects on the fiber-fibrillation process; and (d) the detrimental effect of the prior compression, associated with fiber fibrillation, on the residual longitudinal-tensile strength of the PPTA fibers.

AB Pedemis (PortablE Decoupled Electromagnetic Induction Sensor) is a time-domain man-portable electromagnetic induction (EMI) instrument with the intended purpose of improving the detection and classification of UneXploded Ordnance (UXO). Pedemis sports nine coplanar transmitters (the Tx assembly) and nine triaxial receivers held in a fixed geometry with respect to each other (the Rx assembly) but with that Rx assembly physically decoupled from the Tx assembly allowing flexible data acquisition modes and deployment options. Such flexibility is expected to be instrumental in non-trivial terrains exhibiting either an abundant vegetation or being highly contaminated by large or dense clutter. Before validating the sensor in such challenging configurations, however, Pedemis was taken to Aberdeen Proving Ground, MD, for its first test site validation. We describe Pedemis, including its operation and data acquisition modes along with our Aberdeen Proving Ground results.

AB The U.S. Army Engineer Research and Development Center (ERDC) executes inspection programs as part of the U.S. Army Transportation Infrastructure Program (ATIP). These inspection, monitoring and assessment programs include airfields, bridges, dams, railroads, waterfront facilities and ranges. To date, the process for these inspection programs has been manually intensive, time consuming and difficult to scale. The US Army Corps is bringing digital business and spatial data collection methods to its inspection program for the military's railroad infrastructure. By combining GPS and GIS technologies into a mobile data collection solution, added efficiency and data quality has been brought to the field inspection workflow. This modernization effort also results in streamlined data processing and reporting. These improved processes will lead to higher quality data, better analysis of the new richer data content and better decisions made by the end users and stakeholders.

AB A new strategy was developed for improving basic dye sensitized solar cell (DSSC) performance, using push-pull organic triarylamines with tunable frontier energy levels as additives in the DSSC electron shuttling electrolyte solution. A significant improvement in the device performance was observed and attributed to improved dye regeneration and hole transport.

DE Pedestrian detection; anomaly detection; support vector data
description; unsupervised learning
AB In this paper, an unsupervised pedestrian detection algorithm is proposed. An input image is first divided into overlapping detection windows in a sliding fashion and Histogram of Oriented Gradients (HOG) features are collected over each window using non-overlapping cells. A distance metric is used to determine the distance between histograms of corresponding cells in each detection window and the average pedestrian HOG template (determined a priori). These distances over a group of cells are concatenated to obtain the feature vector pertaining to a block of cells. The feature vectors over overlapping blocks of cells are concatenated to form the distance feature vector of a detection window. Each window provides a data sample and the data samples extracted from the whole image are then modeled as a normalcy class using Support Vector Data Description (SVDD). The benefit of using the state-of-the-art SVDD technique to model the normalcy class is that it can be controlled by setting an upper limit on the permissible outliers during the modeling process. Assuming that most of the image is covered by background, the outliers that are detected during the modeling of the normalcy class can be hypothesized as detection windows that contain pedestrians in them. The detections are obtained at different scales in order to account for the different sizes of pedestrians. The final pedestrian detections are generated by applying non-maximal suppression on all the detections at all scales. The system is tested on the INRIA pedestrian dataset and its performance analyzed with respect to accuracy and detection rate.

AB An energy harvester is proposed consisting of a unimorph where the active layer is a magnetostrictive Iron-Gallium alloy. A theory for predicting the open voltage of the energy harvester in a bending-mode configuration is derived. A constrained optimization is performed using the open voltage as the objective function to identify key geometric and physical parameters that produce the highest root-mean-square voltage. Conclusions about the sensitivity of the voltage to variations in the parameters are also presented. The useful power is calculated, and the effect of changing the pickup-coil configuration is explored.

DE quantum-dot solar cell; potential barriers; photoelectron capture;
photovoltaic efficiency
ID BUILT-IN CHARGE; TRANSITIONS; PLASMONICS
AB Most of investigations of quantum dot photovoltaic devices are aimed at the development of the intermediate band solar cell. To form the intermediate band by quantum dot electron levels, the dots should be placed close to one to another. This leads to strain accumulation and defects, which increase the photocarrier recombination, and recombination losses. To avoid the nanostructuring-induced recombination, we proposed and studied an alternative approach, which is based on the separation of quantum dots (QDs) or QD clusters from the conducting channels by potential barriers created by quantum dots with built-in charge (Q-BIC). Charging of QDs improves the performance of QD solar cells due to the following factors: Negative dot charging increases electron coupling to sub-bandgap photons and provides effective harvesting of IR energy. Because of the strong difference in effective masses of electrons and holes, an electron level spacing in QDs substantially exceeds a level spacing for holes. Therefore, QDs act as deep traps for electrons, but they are shallow traps for holes. Thus, the holes trapped in QDs may be excited by thermal phonons, while excitation of localized QDs electrons requires IR radiation or the interaction with hot electrons. Therefore, n-doping of QD structures is strongly preferable for photovoltaic applications. Charging of QDs is also an effective tool for managing the potential profile at micro-and nanoscales. Filling QDs predominantly from dopants in the QD medium allows one to maintain the macroscale profile analogous to that in the best conventional single-junction solar cells.

AB The Environmental Awareness for Sensor and Emitter Employment (EASEE) software models the impacts of terrain and weather on a diverse range of battlefield sensing systems. The goal is to provide mission planning tools that realistically capture complex environmental factors impacting sensor performance, yet are simple enough for users with little specialized training. This paper describes incorporation of infrared (IR) modeling into EASEE, and the subsequent challenges of supporting imaging sensors within a framework that had previously evolved primarily for non-imaging sensors, such as acoustic and seismic. The design requires independently interchangeable modules for signature generation, propagation, and signal processing. Sensor performance metrics, such as probability of detection, are characterized statistically rather than through simulation of actual images. Some key enhancements needed to support imaging sensors were: (1) geometric models for targets, (2) packaging of multiple attributes representing target image properties (radiance, projected area, and spatial spectrum), (3) explicitly distinguishing between signals for the background, target of interest, and nuisance targets, and (4) calculation of apparent temperature differences (as opposed to incoherent energy summation). Target signatures are generated using MuSES (Multi-Service Electro-optic Signature), whereas the IR background properties are generated using FASST (Fast All-Season Soil STrength) and numerical weather prediction models. Propagation is handled primarily with MODTRAN (MODerate resolution atmospheric TRANsmission), although simpler models such as a line-of-sight calculation can also be employed. The Johnson criteria were added to the available library of detection algorithms.

AB The Environmental Awareness for Sensor and Emitter Employment (EASEE) software, being developed by the U. S. Army Engineer Research and Development Center (ERDC), provides a general platform for predicting sensor performance and optimizing sensor selection and placement in complex terrain and weather conditions. It incorporates an extensive library of target signatures, signal propagation models, and sensor systems. A flexible object-oriented design supports efficient integration and simulation of diverse signal modalities. This paper describes the integration of modeling capabilities for radio-frequency (RF) transmission and radar systems from the U. S. Navy Electromagnetic Propagation Integrated Resource Environment (EMPIRE), which contains nearly twenty different realistic RF propagation models. The integration utilizes an XML-based interface between EASEE and EMPIRE to set inputs for and run propagation models. To accommodate radars, fundamental improvements to the EASEE software architecture were made to support active-sensing scenarios with forward and backward propagation of the RF signals between the radar and target. Models for reflecting targets were defined to apply a target-specific, directionally dependent reflection coefficient (i.e., scattering cross section) to the incident wavefields.

AB This paper describes the ongoing development of a robotic control architecture that inspired by computational cognitive architectures from the discipline of cognitive psychology. The Symbolic and Sub-Symbolic Robotics Intelligence Control System (SS-RICS) combines symbolic and sub-symbolic representations of knowledge into a unified control architecture. The new architecture leverages previous work in cognitive architectures, specifically the development of the Adaptive Character of Thought-Rational (ACT-R) and Soar. This paper details current work on learning from episodes or events. The use of episodic memory as a learning mechanism has, until recently, been largely ignored by computational cognitive architectures. This paper details work on metric level episodic memory streams and methods for translating episodes into abstract schemas. The presentation will include research on learning through novelty and self generated feedback mechanisms for autonomous systems.

Two possible configurations are considered, corresponding to an airborne spotlight and a ground-based strip-map geometry. The paper details all the steps involved in this analysis: creating the computational meshes, calculating the radar signals scattered by the target, forming the radar images, and processing the images for visualization and interpretation. Particular attention is given to the scattering phenomenology and its dependence on the system geometry. The images are created via the backprojection algorithm and further processed using a constant false-alarm rate (CFAR) detector. We discuss methods of 3-D image visualization and interpretation of the results.

AB Experimental results from recent field testing with the noise correlation radar (NCR) are presented as a proof of concept. In order to understand the effectiveness of the NCR, a pre-determined set of measures is established. We discuss the three experimental configurations used in evaluating the system's range resolution/error, robustness to interference, and secure radio frequency (RF) emission. We show that the advanced pulse compression noise (APCN) radar waveform has low range measurement error, is robust to interference, and is spectrally non-deterministic. In addition, we determine that an improvement in range resolution due to phase modulation is achieved as a function of the random code length rather than the compressed pulse length.

AB Providing situational awareness to the warfighter requires radar, communications, and other electronic systems that operate in increasingly cluttered and dynamic electromagnetic environments. There is a growing need for cognitive RF systems that are capable of monitoring, adapting to, and learning from their environments in order to maintain their effectiveness and functionality. Additionally, radar systems are needed that are capable of adapting to an increased number of targets of interest. Cognitive nonlinear radar may offer critical solutions to these growing problems. This work focuses on ongoing efforts at the U.S. Army Research Laboratory (ARL) to develop a cognitive nonlinear radar test-bed. ARL is working toward developing a test-bed that uses spectrum sensing to monitor the RF environment and dynamically change the transmit waveforms to achieve detection of nonlinear targets with high confidence. This work presents the architecture of the test-bed system along with a discussion of its current capabilities and limitations. A brief outlook is presented for the project along with a discussion of a future cognitive nonlinear radar test-bed.

AB Large-scale, full-wave modeling of multistatic target imaging in a rough ground environment is described. The emulation methodology employs a parallelized three-dimensional "near-field" finite-difference time-domain algorithm in characterizing the electromagnetic scattering from the ground surface and buried and on-surface targets in the form of landmines and unexploded ordnances; subsequent focusing of the scattered fields into an image is obtained with the time-reversal technique. The emphasis of this study is on investigating the detectability of discrete ground targets in the presence of distributed variable ground clutter as relevant to performance prediction for ultra-wideband forward-looking radar applications.

AB An increasingly cluttered electromagnetic environment (EME) is a growing problem for radar systems. This problem is becoming critical as the available frequency spectrum shrinks due to growing wireless communication device usage and changing regulations. A possible solution to these problems is cognitive radar, where the cognitive radar learns from the environment and intelligently modifies the transmit waveform. In this paper, a cognitive nonlinear radar processing framework is introduced where the main components of this framework consist of spectrum sensing processing, target detection and classification, and decision making. The emphasis of this paper is to introduce a spectrum sensing processing technique that identifies a transmit-receive frequency pair for nonlinear radar. It will be shown that the proposed technique successfully identifies a transmit-receive frequency pair for nonlinear radar from data collected from the EME.

AB Nonlinear radar exploits the electronic response from a target whose reflected frequencies are different from those transmitted. Reception of frequencies that are not part of the transmitted probe distinguishes the received signal from a linear return produced by clutter and indicates the presence of electronics. Presented in this paper is a type of nonlinear radar that transmits multiple frequencies and listens for a harmonic of these frequencies as well as other frequencies near that harmonic. A laboratory test-bed has been constructed to demonstrate the multitone radar concept. Measurements of nonlinear responses from RF devices probed by multiple tones are reported.

AB Multiple-input multiple-output (MIMO) radar systems have been shown to have significant performance improvements over their single-input multiple-output (SIMO) counterparts. For transmit and receive elements that are collocated, the waveform diversity afforded by this radar is exploited for performance improvements. These improvements include but are not limited to improved target detection, improved parameter identifiability and better resolvability. In this paper, we present the Synchronous Impulse Reconstruction Radar (SIRE) Ultra-wideband (UWB) radar designed by the Army Research Lab (ARL) for landmine and improvised explosive device (IED) detection as a 2 by 16 MIMO radar (with collocated antennas). Its improvement over its SIMO counterpart in terms of beampattern/cross range resolution are discussed and demonstrated using simulated data herein. The limitations of this radar for Radio Frequency Interference (RFI) suppression are also discussed in this paper. A relaxation method (RELAX) combined with averaging of multiple realizations of the measured data is presented for RFI suppression; results show no noticeable target signature distortion after suppression. In this paper, the back-projection (delay and sum) data independent method is used for generating SAR images. A side-lobe minimization technique called recursive side-lobe minimization (RSM) is also discussed for reducing side-lobes in this data independent approach. We introduce a data-dependent sparsity based spectral estimation technique called Sparse Learning via Iterative Minimization (SLIM) as well as a data-dependent CLEAN approach for generating SAR images for the SIRE radar. These data-adaptive techniques show improvement in side-lobe reduction and resolution for simulated data for the SIRE radar.

DE Ground-Penetrating Radar; Concealed Targets; Spectrum Control;
Stepped-Frequency Radar
AB The design of high-resolution radars which can operate in theater involves a careful consideration of the radar's radiated spectrum. While a wide bandwidth yields better target detectability and classification, it can also interfere with other devices and/or violate federal and international communication laws. Under the Army Research Laboratory (ARL) Partnerships in Research Transition (PIRT) program, we are developing a Stepped-Frequency Radar (SFR) which allows for manipulation of the radiated spectrum, while still maintaining an effective ultra-wide bandwidth for achieving good range resolution. The SFR is a forward-looking, ultra-wideband (UWB) imaging radar capable of detecting concealed targets. This paper presents the research and analysis undertaken during the design of the SFR which will eventually complement an existing ARL system, the Synchronous Impulse REconstruction (SIRE) radar. The SFR is capable of excising prohibited frequency bands, while maintaining the down-range resolution capability of the original SIRE radar. The SFR has two transmit antennas and a 16-element receive antenna array, and this configuration achieves suitable cross-range resolution for target detection. The SFR, like the SIRE radar, is a vehicle mounted, forward-looking, ground penetrating radar (GPR) capable of using synthetic aperture radar (SAR) technology for the detection of subsurface targets via 3D imaging. Many contradicting design considerations are analyzed in this paper. The selection of system bandwidth, antenna types, number of antennas, frequency synthesizers, digitizers, receive amplifiers, wideband splitters, and many other components are critical to the design of the SFR. Leveraging commercial components and SIRE sub-systems were design factors offering an expedited time to the initial implementation of the radar while reducing overall costs. This SFR design will result in an ARL asset to support obscured target detection such as improvised explosive devices (IEDs) and landmines.

AB The problem of detecting buried objects has engaged radar system developers for quite some time. Many systems-both experimental and commercial-have been developed, including vehicle-mounted systems that look beneath road surfaces. Most of these downward-looking systems exploit multiple transmit and receive channels to enhance resolution in the final radar imagery used for target detection. In such a system, the configuration and operation of the various transmit and receive elements play a critical role in the quality of the output imagery. In what follows, we leverage high-fidelity electromagnetic model data to examine a multistatic downward-looking radar system. We evaluate the signatures produced by various targets of interest and describe, both qualitatively and quantitatively, the variations in target signatures produced by different system configurations. Finally, we analyze the underlying physics of the problem to explain certain characteristics in the observed target signatures.

AB The Synchronous Impulse Reconstruction (SIRE) forward-looking radar, developed by the U. S. Army Research Laboratory (ARL), can detect concealed targets using ultra-wideband synthetic aperture technology. The SIRE radar has been mounted on a Ford Expedition and combined with other sensors, including a pan/tilt/zoom camera, to test its capabilities of concealed target detection in a realistic environment. Augmented Reality (AR) can be used to combine the SIRE radar image with the live camera stream into one view, which provides the user with information that is quicker to assess and easier to understand than each separated.
In this paper we present an AR system which utilizes a global positioning system (GPS) and inertial measurement unit (IMU) to overlay a SIRE radar image onto a live video stream. We describe a method for transforming 3D world points in the UTM coordinate system onto the video stream by calibrating for the intrinsic parameters of the camera. This calibration is performed offline to save computation time and achieve real time performance. Since the intrinsic parameters are affected by the zoom of the camera, we calibrate at eleven different zooms and interpolate. We show the results of a real time transformation of the SAR imagery onto the video stream. Finally, we quantify both the 2D error and 3D residue associated with our transformation and show that the amount of error is reasonable for our application.

AB This paper presents a processing technique that can be used to detect and classify pedestrians group based on the micro-Doppler signature gathered with a millimeter wave radar. The evaluation of the number of pedestrians moving in a group can be a difficult task using a traditional micro-Doppler spectrogram because of a tendency for people to partially synchronize their steps when walking together. The new approach, based on multi-range variation as well as the micro-Doppler variations, provides promising results. The range-spectrogram processing technique was developed and tested using a database composed of hundreds of pedestrian and vehicle signatures gathered in an urban test site over a two year period in a variety of weather conditions. We associate image detections with radar detections through motion extracted from both radar and imagery. We also explain how radar and video together can produce an inexpensive alternative to 3-D imaging.

radiation
AB Passive infrared (PIR) sensors are widely used as a part of unattended ground sensor suite for situational awareness. Currently, the PIR sensor is mainly used as a wakeup sensor for the imaging sensor in order to conserve power. Since the PIR sensor mainly responds to the thermal radiation from the target, animals in the vicinity of the sensor can cause many false alarms. The number of false alarms can be cut drastically, if the target's size can be estimated and a decision is made based on target size. For example, if the target is 5 ft 9 in tall and 1.5 ft wide, it is most likely a human being as opposed to an animal. In this paper, we present a technique to estimate target size using two PIR sensors with Fresnel lens arrays. One of the PIR sensors is mounted such that its Fresnel zones are horizontal to the ground, and the second PIR sensor is mounted such that its Fresnel zones are at a slant angle to the horizontal plane. The former is used to estimate the width/length, while the latter is used to estimate the height of the target. The relative signal strength between the two sensors is used to estimate the distance of the target from the sensor. The time it takes to cross the Fresnel zones is used to estimate the speed of the target. The algorithm is tested using the data collected in the woods, where several animals are observed roaming.

DE social network analysis; visualization software; graph matching
AB Software tools for Social Network Analysis (SNA) are being developed which support various types of analysis of social networks extracted from social media websites (e.g., Twitter). Once extracted and stored in a database such social networks are amenable to analysis by SNA software. This data analysis often involves searching for occurrences of various subgraph patterns (i.e., graphical representations of entities and relationships). The authors have developed the Graph Matching Toolkit (GMT) which provides an intuitive Graphical User Interface (GUI) for a heuristic graph matching algorithm called the Truncated Search Tree (TruST) algorithm. GMT is a visual interface for graph matching algorithms processing large social networks. GMT enables an analyst to draw a subgraph pattern by using a mouse to select categories and labels for nodes and links from drop-down menus. GMT then executes the TruST algorithm to find the top five occurrences of the subgraph pattern within the social network stored in the database. GMT was tested using a simulated counter-insurgency dataset consisting of cellular phone communications within a populated area of operations in Iraq. The results indicated GMT (when executing the TruST graph matching algorithm) is a time-efficient approach to searching large social networks. GMT's visual interface to a graph matching algorithm enables intelligence analysts to quickly analyze and summarize the large amounts of data necessary to produce actionable intelligence.

ID FIELD-EFFECT TRANSISTOR; RADIATION; FLUID
AB In the Dyakonov-Shur terahertz (THz) detector, nonlinearities in the plasma wave propagation in the conduction channel of a heterostructure High Electron Mobility Transistor (HEMT) lead to a constant source-to-drain voltage providing the detector output. For a small signal, the perturbation theory treatment shows that the response is proportional to the intensity of the radiation. The proportionality factor can have a resonant or a broad dependence on the signal frequency. For submicron HEMTs, the typical measured response falls within the range of 0.1 to 4.5 THz. The deviations from this relation have been studied and reported in the approximation of the local Ohm's law and transmission line model for the non-resonant response. Here we present the results obtained with the hydrodynamic model using the electron plasma Navier-Stokes equation, thus fully accounting for the hydrodynamic non-linearity, the viscosity and pressure gradients in the detector response. The model is applicable to both resonant and broadband operations of the HEMT based plasmonic detectors. The relation between the electron channel density and gate voltage was modeled by the unified charge control model applicable both above and below the threshold voltage. The theoretical results are compared with the response measured in the short channel InGaAs HEMT and the analytical approximation. The THz source was operating at 1.63 THz and the response was measured at varying signal intensities. The response of the detector operated in the open drain mode was measured above and below the threshold. The theoretical and experimental results are in good agreement.

AB A simple, quantitative measure for encapsulating the autonomous capabilities of unmanned systems (UMS) has yet to be established. Current models for measuring a UMS's autonomy level require extensive, operational level testing, and provide a means for assessing the autonomy level for a specific mission/task and operational environment. A more elegant technique for quantifying autonomy using component level testing of the robot platform alone, outside of mission and environment contexts, is desirable. Using a high level framework for UMS architectures, such a model for determining a level of autonomy has been developed. The model uses a combination of developmental and component level testing for each aspect of the UMS architecture to define a non-contextual autonomous potential (NCAP). The NCAP provides an autonomy level, ranging from fully non-autonomous to fully autonomous, in the form of a single numeric parameter describing the UMS's performance capabilities when operating at that level of autonomy.

AB Autonomous systems operating in militarily-relevant environments are valuable assets due to the increased situational awareness they provide to the Warfighter. To further advance the current state of these systems, a collaborative experiment was conducted as part of the Safe Operations of Unmanned Systems for Reconnaissance in Complex Environments (SOURCE) Army Technology Objective (ATO). We present the findings from this large-scale experiment which spanned several research areas, including 3D mapping and exploration, communications maintenance, and visual intelligence.
For 3D mapping and exploration, we evaluated loop closure using Iterative Closest Point (ICP). To improve current communications systems, the limitations of an existing mesh network were analyzed. Also, camera data from a Microsoft Kinect was used to test autonomous stairway detection and modeling algorithms. This paper will detail the experiment procedure and the preliminary results for each of these tests.

AB Currently fielded small unmanned ground vehicles (SUGVs) are operated via teleoperation. This method of operation requires a high level of operator involvement within, or near within, line of sight of the robot. As advances are made in autonomy algorithms, capabilities such as automated mapping can be developed to allow SUGVs to be used to provide situational awareness with an increased standoff distance while simultaneously reducing operator involvement.
In order to realize these goals, it is paramount the data produced by the robot is not only accurate, but also presented in an intuitive manner to the robot operator. The focus of this paper is how to effectively present map data produced by a SUGV in order to drive the design of a future user interface. The effectiveness of several 2D and 3D mapping capabilities was evaluated by presenting a collection of pre-recorded data sets of a SUGV mapping a building in an urban environment to a user panel of Soldiers. The data sets were presented to each Soldier in several different formats to evaluate multiple factors, including update frequency and presentation style. Once all of the data sets were presented, a survey was administered. The questions in the survey were designed to gauge the overall usefulness of the mapping algorithm presentations as an information generating tool. This paper presents the development of this test protocol along with the results of the survey.

AB We document initial experiments with Canid, a freestanding, power-autonomous quadrupedal robot equipped with a parallel actuated elastic spine. Research into robotic bounding and galloping platforms holds scientific and engineering interest because it can both probe biological hypotheses regarding bounding and galloping mammals and also provide the engineering community with a new class of agile, efficient and rapidly-locomoting legged robots. We detail the design features of Canid that promote our goals of agile operation in a relatively cheap, conventionally prototyped, commercial off-the-shelf actuated platform. We introduce new measurement methodology aimed at capturing our robot's "body energy" during real time operation as a means of quantifying its potential for agile behavior. Finally, we present joint motor, inertial and motion capture data taken from Canid's initial leaps into highly energetic regimes exhibiting large accelerations that illustrate the use of this measure and suggest its future potential as a platform for developing efficient, stable, hence useful bounding gaits.

AB Tactical situational awareness in unstructured and mixed indoor/ outdoor scenarios is needed for urban combat as well as rescue operations. Two of the key functionalities needed by robot systems to function in an unknown environment are the ability to build a map of the environment and to determine its position within that map. In this paper, we present a strategy to build dense maps and to automatically close loops from 3D point clouds; this has been integrated into a mapping system dubbed OmniMapper. We will present both the underlying system, and experimental results from a variety of environments such as office buildings, at military training facilities and in large scale mixed indoor and outdoor environments.

AB The market for military-use Generation 2 and Generation 3 image intensifier (I2) tubes has become truly global, with major manufacturers and customers spanning five continents. This worldwide market is becoming increasingly important to U. S. manufacturers, with the majority of U. S. Army intensifier fielding having been completed in 2012. Given this keen global competition, it is not surprising that the advertised tube performance of a given source is often discounted by competitors, and the customers have no objective "honest broker" to determine the relative accuracy of these claims. To help fill this void, the U. S. Army RDECOM CERDEC NVESD recently measured a number of domestic and foreign image intensifier tubes, using consistent test equipment/procedures with which the U. S. industry must correlate for Army tube deliveries. Data and analysis will be presented for the major tube parameters of luminance gain, equivalent background input (EBI), signal-to-noise ratio (SNR), limiting resolution, halo, and modulation transfer function (MTF). The bright-light resolution provided by various auto-gated and non-gated tubes will also be addressed, since this area has been an important factor in the international market. RDECOM CERDEC NVESD measurement data will be compared to the corresponding manufacturer specifications whenever possible.

Infrared Cameras; Calibration
AB Infrared imaging is commonly used for performing thermography based on field calibration that simply relates image levels to apparent temperature levels using field blackbodies. Under normal conditions, the correlation between the image levels and blackbody temperature is strong, allowing conversion of the raw data into units of blackbody-equivalent temperature without consideration of other factors. However, if certain instrument anomalies are present, a compensation procedure that involves more in-depth sensor characterization may be required. The procedure, which uses an analysis of temperature-dependent dark current, optical emissions, and detector response, is described along with results for a specific case. The procedure involves first cold soaking a thermal camera and then observing the cooldown behavior of the sensor under non-stressing conditions. Variations in environmental temperature levels are then used to observe cooler performance and dark current levels. A multi-variate linear regression is performed that allows temperature-dependent dark current, lens emission, lens transmission, and detector quantum efficiency to be fully characterized. The resulting data describe for each image pixel a relationship between the scene temperature and the observed values of image signal, detector temperature, and camera temperature. The procedure has been applied successfully to a thermal imager used to collect field data while suffering from instrument anomalies due to a faulty cooler. Using the resulting characterization data for the pixel-dependent dark current, image data collected with the thermal imager was compensated. The compensation involved using spatial filtering to determine temperature shifts caused by the faulty cooler based on the predictable pattern of pixel-to-pixel variations in dark current. The estimated temperature shift was used to compute a compensation offset for each pixel based on its known dark current coefficient. The compensated image data, while still degraded, was sufficiently corrected for the predictable effects of dark current variations to allow valid thermography to be performed.

AB In this paper the mean time to acquire a stationary target by n stationary imaging sensors is computed using probability theory by making use of the well established result that the detection time for a single imaging sensor is a random variable from an exponential probability density function. Each imaging sensor is characterized by a separate P-infinity value which describes the probability an observer using that sensor will eventually acquire the target and a separate tau value which describes the mean time to acquire the target using that sensor. There is no restriction on the wavelength band used by the imaging sensor. There are no empirical constants in the model presented here and the results are in agreement with and generalize previously published equations. The newly developed equations have been verified by numerical simulations and also yield the expected mean detection time for all limiting values of the input parameters. The code used in the numerical simulations is exhibited. For any given scenario, the separate observer-sensor-target parameters P-infinity and tau can be estimated using the NV-IPM model or measured in perception experiments. Thus the input parameters needed by the model are generally available. Comparing results presented here with results from war game simulations such as OneSAF may improve the quality of both products.

AB The spectroscopic properties of Ho3+-doped YVO4 were studied at cryogenic and room temperatures in the 2 mu m spectral region to clarify recent observations of efficient dual-wavelength laser operation in this material. Polarized absorption cross sections were measured, and stimulated emission cross sections were determined using the reciprocity method coupled with Fuchtbauer-Ladenburg calculations. The observed laser emission wavelengths were at 2041.7 nm, 2054.2 nm, and 2068.5 nm; the first two corresponding to pi transitions and the third to a sigma transition. Gain cross section calculations were used to predict which of the three wavelengths would lase for a given output coupler reflectivity. In depth analysis of the gain cross section in the region between 80 K and 100 K showed that the laser output wavelength is very susceptible to minor changes in temperature.

DE sesquioxide; erbium; Lu2O3; Sc2O3; Y2O3; absorption; stimulated emission
AB Due to the favorable thermal properties of sesquioxides as hosts for rare earth laser ions, we have recently studied the spectroscopy of Er:Lu2O3 in the 1400-1700 nm wavelength range, and here report its comparison with our earlier results on Er:Y2O3 and Er:Sc2O3. These studies include absorption and fluorescence spectra, fluorescence lifetimes, and inference of absorption and stimulated emission cross sections, all as a function of temperature. At room temperature, optical absorption limits practical laser operation to wavelengths longer than about 1620 nm. In that spectral range, the strongest stimulated emission peak is that at 1665 nm in Er:Sc2O3, with an effective cross section considerably larger than those of Er:Y2O3 and Er:Lu2O3. At 77K, the absorption is weak enough for efficient laser operation at considerably shorter wavelengths, where there are peaks with much larger stimulated emission cross sections. The three hosts all have peaks near 1575-1580 nm with comparably strong cross sections. As we have reported earlier, it is possible to lase even shorter wavelengths efficiently at this temperature, in particular the line at 1558 nm in Er:Sc2O3. Our new spectroscopic studies of Er:Lu2O3 indicate that its corresponding peak, like that of Er:Y2O3, has a less favorable ratio of stimulated emission to absorption cross sections. Reasons for the differences will be discussed. We conclude that for most operating scenarios, Er:Sc2O3 is the most promising of the Er-doped sesquioxides studied for laser operation around 1.5-1.6 microns.

AB We demonstrated nearly a quantum defect limited CW operation of a 41-mm-long Er:YAG large area crystalline waveguide laser with a diffraction limited output, which was resonantly pumped by a fiber laser at 1532 nm. Using a Er(0.25%): YAG, 62 mu m x 62 mu m waveguide, surrounded by a 3 x 5 mm rectangular cladding of undoped YAG, an output power of 9.1 W with slope efficiency of 92.8% has been achieved. The output laser beam had a Gaussian profile with a similar to 2.8 x 10(-2) rad divergence, which is in good agreement with the divergence expected from a waveguide with a low NA value. The waveguide laser operated simultaneously at two wavelengths, 1617 nm and 1645 nm, when the transmission of the laser cavity output coupler was less than 20-25%, and operated only at 1617 nm when the laser output mirror had a higher transmission.

AB Cotton seed oil is a renewable resource that can potentially be blended with fossil fuels for power generation. The primary objective of this work was to identify analytical techniques that can be performed on the field to discern poppy seed oil from cotton seed oil. It was determined that it is feasible to distinguish poppy and cotton seed oil samples using reverse phase high performance thin layer chromatography (HPTLC) and viscosity measurement. Other seed oils including soybean and canola seed oils were also evaluated to understand the limitations of these analytical techniques. Viscosity measurement was determined to be effective to distinguish cotton seed oil from poppy or soybean seed oil, but it failed to distinguish cotton and canola seed oils. To maximize the HPTLC separation of the oils without pretreatment, different solvent mixtures were studied: isopropyl alcohol, 1-butanol, methanol, hexane, dioxane, and distilled water. The purpose of mixing solvents was to tailor a solution with moderate polarity to achieve the best separation with the HPTLC plates. The most promising mixtures were butanol-methanol at the ratio of 80:20% and 90:10%. In the 80:20 mixture, R-f values increased in the order of poppy, canola, cotton, and soybean, while in the 90:10 mixture the order was reversed. With this technique the oil polarity can be ranked in increasing polarity: poppy < canola < cotton < soybean. This showed that the various compounds making up the oil have varying levels of polarity, and thus lessen in concentration at varying levels as the analyte moves up the plate. Raman spectroscopy (microscopy) was employed to characterize the oils by locating cis C=C vibrational peak at 1654cm(-1) on the oil smear that decreased as the analyte moved up the stationary phase.

AB Glutamate is the primary excitatory neurotransmitter used by the central nervous system (CNS) for synaptic communication, and its extracellular concentration is tightly regulated by glutamate transporters located on nearby astrocytes. Both animal models and human clinical studies have demonstrated elevated glutamate levels immediately following a traumatic brain event, with the duration and severity of the rise corresponding to prognosis. This rise in extracellular glutamate likely results from a combination of excessive neurotransmitter release from damaged neurons and down regulation of uptake mechanisms in local astrocytes. The immediate results of a traumatic event can lead to necrotic tissue in severely injured regions, while prolonged increases in excitatory transmission can cause secondary excitotoxic injury through activation of delayed apoptotic pathways. Initial TBI animal studies utilized a variety of broad glutamate receptor antagonists to successfully combat secondary injury mechanisms, but unfortunately this same strategy has proven inconclusive in subsequent human trials due to deleterious side effects and heterogeneity of injuries. More recent treatment strategies have utilized specific glutamate receptor subunit antagonists in an effort to minimize side effects and have shown promising results. Future challenges will be detecting the concentration and kinetics of the glutamate rise following injury, determining which patient populations could benefit from antagonist treatment based on their extracellular glutamate concentrations and when drugs should be administered to maximize efficacy.

AB We have developed a new type of Si-based 3D cage-like high-contrast metastructure waveguide with both "slow-light" and low-loss properties, which has applications in providing a long time-delay line or a high Q cavity in chip-scale opto-electronic integrated circuits (OEIC). Traditional semiconductor optical waveguides always have high loss when used in a high dispersion (slow-light) region. A preliminary computational model has predicted that there is a slow-light and low propagation loss region within cage-like hollow-core waveguide formed by 4 high-contrast-gratings walls/claddings. Using our new processing technique, we fabricated several such waveguides on a Si wafer with different core sizes/shapes and different HCGs for 1550 operation wavelength. We have conducted experimental waveguide delay test measurements using a short optical pulse which indicate that the group velocity of these metastructure waveguides are in the range of 20- 30% of the speed of the light. Using a waveguide "cut-back" method, we have experimentally determined the propagation loss of these waveguides are in the range of 2-5dB/cm. We are also developing this type of high-contrast metastructure hollow-core waveguide for different operating wavelength/frequency such as THz for different applications.

AB Laser altimetry (lidar) is a remote-sensing technology that holds tremendous promise for mapping snow depth in snow hydrology and avalanche applications. Recently lidar has seen a dramatic widening of applications in the natural sciences, resulting in technological improvements and an increase in the availability of both airborne and ground-based sensors. Modern sensors allow mapping of vegetation heights and snow or ground surface elevations below forest canopies. Typical vertical accuracies for airborne datasets are decimeter-scale with order 1 m point spacings. Ground-based systems typically provide millimeter-scale range accuracy and sub-meter point spacing over 1 m to several kilometers. Many system parameters, such as scan angle, pulse rate and shot geometry relative to terrain gradients, require specification to achieve specific point coverage densities in forested and/or complex terrain. Additionally, snow has a significant volumetric scattering component, requiring different considerations for error estimation than for other Earth surface materials. We use published estimates of light penetration depth by wavelength to estimate radiative transfer error contributions. This paper presents a review of lidar mapping procedures and error sources, potential errors unique to snow surface remote sensing in the near-infrared and visible wavelengths, and recommendations for projects using lidar for snow-depth mapping.

AB A molecular dynamics simulation study of electric double layer (EDL) structure and differential capacitance (DC) of two 1-butyl-3-methylimidazolium (BMIM)-based room temperature ionic liquids, i.e. [BMIM][BF4] and [BMIM][PF6], has been conducted on basal and prismatic graphite as well as (001) and (011) gold electrode surfaces. The influence of the electrode surface and electrolyte structure on electrode capacitance and EDL structure are discussed. For a given electrode surface both the [BMIM][BF4] and [BMIM][PF6] electrolytes generate very similar DC and EDL structures. The DC for these ionic liquids in contact with atomically flat surfaces (i.e. basal graphite and (001)Au) shows very small variations within the electrolyte chemical stability potential window and fluctuates around an average value of similar to 5 mu F cm(-2). On atomically more corrugated surfaces (i.e., Au(011) and prismatic graphite) the DC shows more variation with electrode potential and depends on the correspondence between dimensions of the surface roughness and electrolyte ion sizes. The trends and dependencies obtained for DC are used to discriminate between mutually contradictory experimental data reported in the literature for related systems.

AB Measurements of gaseous elemental mercury (GEM), reactive gaseous mercury (RGM) and particulate mercury (PHg) were collected on the Beaufort Sea ice near Barrow, Alaska, in March 2009 as part of the Ocean-Atmosphere-Sea Ice-Snowpack (OASIS) and OASIS-Canada International Polar Year programmes. These results represent the first atmospheric mercury speciation measurements collected on the sea ice. Concentrations of PHg averaged 393.5 pg m(-3) (range 47.1-900.1 pg m(-3)) and RGM concentrations averaged 30.1 pg m(-3) (range 3.5-105.4 pg m(-3)) during the two-week-long study. The mean concentration of GEM during the study was 0.59 ng m(-3) (range 0.01-1.51 ng m(-3)) and was depleted compared to annual Arctic ambient boundary layer concentrations. It is shown that when ozone (O-3) and bromine oxide (BrO) chemistry were active there is a positive linear relationship between GEM and O-3, a negative one between PHg and O-3, a positive correlation between RGM and BrO, and none between RGM and O-3. For the first time, GEM was measured simultaneously over the tundra and the sea ice. The results show a significant difference in the magnitude of the emission of GEM from the two locations, with significantly higher emission over the tundra. Elevated chloride levels in snow over sea ice are proposed to be the cause of lower GEM emissions over the sea ice because chloride has been shown to suppress photoreduction processes of RGM to GEM in snow. Since the snowpack on sea ice retains more mercury than inland snow, current models of the Arctic mercury cycle may greatly underestimate atmospheric deposition fluxes because they are based predominantly on land-based measurements. Land-based measurements of atmospheric mercury deposition may also underestimate the impacts of sea ice changes on the mercury cycle in the Arctic. The predicted changes in sea ice conditions and a more saline future snowpack in the Arctic could enhance retention of atmospherically deposited mercury and increase the amount of mercury entering the Arctic Ocean and coastal ecosystems.

ID MODEL
AB Airborne laser scanning light detection and ranging (LiDAR) systems are used for remote sensing topology and bathymetry. The most common data collection technique used in LiDAR systems employs a linear mode scanning. The resulting scanning data form a non-uniformly sampled 3D point cloud. To interpret and further process the 3D point cloud data, these raw data are usually converted to digital elevation models (DEMs). In order to obtain DEMs in a uniform and upsampled raster format, the elevation information from the available non-uniform 3D point cloud data are mapped onto the uniform grid points. After the mapping is done, the grid points with missing elevation information are filled by using interpolation techniques. In this paper, partial differential equations (PDE) based approach is proposed to perform the interpolation and to upsample the 3D point cloud onto a uniform grid. Due to the desirable effects of using higher order PDEs, smoothness is maintained over homogeneous regions, while sharp edge information in the scene well preserved. The proposed algorithm reduces the draping effects near the edges of distinctive objects in the scene. Such annoying draping effects are commonly associated with existing point cloud rendering algorithms. Simulation results are presented in this paper to illustrate the advantages of the proposed algorithm.

AB Current Army acquisition policy states that systems shall demonstrate reliability requirements with high confidence, but the policy fails to state what 'high' confidence means. Despite this, for every system there is an optimal confidence level with which to demonstrate the reliability requirement. The optimal confidence level may be driven by many competing factors including cost, schedule, Soldier safety, and mission criticality. Most of these factors are difficult to quantify, and leave the community to make a judgment call on the appropriate confidence level. In the absence of other driving or quantifiable metrics, one way to choose an optimal confidence level is to balance test cost against the risk to life cycle cost.
This method deals in a natural metric: money. It is easily understood by the layman, and is straightforward to compare to most other programmatic risks. Conveniently it provides objective support for the common sense solution that inexpensive systems (to buy and test) that will be purchased in large quantities should be tested at higher confidence, while expensive systems (to buy and test) bought in low quantities possibly should be tested at lower confidence. If the other factors are not overwhelming, or do not suggest a particular confidence level, confidence can be optimized by balancing test cost against life cycle cost.

AB In military applications electronic devices play a vital role in the success of a mission. These devices which provide control, guidance, communication, and reconnaissance are critical components in modern unmanned vehicular applications. The current trend is to provide a human interface to control theses systems via portable devices. This trend in modern warfare has increased the complexity of electronic equipment, especially in low volume, highly sophisticated, and dense electronic systems. These modern devices take advantage of the remarkable advances made in low cost commercial electronics. This current movement of using commercial-off-the-shelf (COTS) electronics and devices for military applications has led to concerns about their reliability in harsh battlefield environments. The increase in the use of COTS components lead to the need to improve the reliability of these components by understanding the failure mechanisms due to thermal loads, dynamic vibration, and shock through Physics of Failure (PoF) analyses.
Unfortunately, current military standards do not provide an adequate approach to analyze, design, or test for those types of complex portable electronic systems. In some cases, the loading profiles may be over-conservative and in others under-conservative and not representative of the operational conditions. In this paper, a PoF approach is provided to understand the failure mechanisms experienced by these devices during their life-cycle. In this study, the life-cycle of portable handheld electronic device was modeled. The life-cycle included thermal loading from diurnal cycles and power cycles and vibration loads due to transportation.. The transient response of electronic assemblies to mechanical loading encountered in drop and shock conditions was simulated. These loads may impose significant stresses on the Printed Circuit Board (PCB) substrate, component packages, leads, and solder joints. Explicit finite element analysis combined with computational thermal analysis and analytical models have been utilized to uncover potential failure modes. To reduce the computational time and cost, modified shell elements were used to model the circuit card assemblies (CCAs). Failure modes predicted by the modeling and simulation were utilized to assess the overall reliability of the portable device.
This study demonstrates how a PoF approach may provide an understanding of the loads experienced by the electronics and how they affect the reliability of the device. This is critical to developing and acquiring more reliable systems as the DoD begins to utilize more advanced portable electronics systems.

AB The quantity and frequency of non-destructive testing (NDT) across the life cycle of a missile inventory must be carefully considered. This paper provides a process for optimizing the quantity of missiles subject to NDT across the life of the missile inventory. This process ensures that the program does not exceed the minimum test quantity necessary to ensure that the inventory continues to meet the user's reliability requirement based on the predicted failure probability and annual test quantity. The methodology takes into account the age distribution of the inventory, tested/untested populations, removal of failing hardware, and items with multiple tests through the system life. The analysis also provides an estimate of the minimum and maximum test time that missiles will be exposed to across the projected life of the inventory. The paper provides an example of the process as applied to a representative Army missile system. This example demonstrates the practicality and simplicity of the process. The affect of varying levels of NDT on the inventory reliability is readily apparent in graphical form that facilitates the Reliability Engineer in presenting options to the Program Manager for making sustainment decisions. Overall, the U. S. Army Stockpile Reliability Program (SRP) has repeatedly demonstrated successes in identifying trends, ensuring readiness, and justifying missile shelf life extensions. However, under the current era of decreasing defense budgets, and expectations to push the life of existing missile systems out without replacement, NDT costs should be minimized while simultaneously minimizing the wear of those tests on the inventory. The approach outlined in this paper can be used to accomplish this on either the existing NDT program for a fielded system, or by the Program Manager developing a SRP program plan for a new missile system.

AB The objective of this paper on Software Reliability (SWR) is to provide a practical approach to implementing a SWR program for Army software intensive system acquisition planning and subsequent software development activities. The goal of this paper will be to leave the reader with the understanding that there is no magic to implement a robust SWR strategy and also to show that there is an abundance of information available from a myriad of industry sources on the subject. I don't intend to list those sources here; the reader can just do an internet search. The point I am making is that like any good "Bootlegger", my intent is to "distill" various ingredients, in this case, industry knowledge on software reliability and adopt a strategy that bests suits my particular organization. This strategy can be adopted in its entirety or tweaked to suit specific organizational needs. Regardless of any strategy that is adopted, it is critical that appropriate statement of work or contract language needs to be specified when acquiring software from a supplier or developing it from an in-house source. Finally, like any idea this one needs a home. There were Software Reliability requirements in the Software Development Plan of a large, now cancelled, software intensive Army program but the requirements were nebulous and some of the reference documents were out of date. Unfortunately, a good number of software problems ultimately labeled "Software Reliability defects" caused both formal laboratory and field testing delays. A robust SWR program may have avoided those costly rework efforts and delays. Unlike System Safety (incl Software) (MIL-STD-882E) or Information Assurance Certification (DIACAP), there is no official mandate or specific policy for Software Reliability Process compliance for Army Programs. However, I did manage to defend getting SWR contract language into the Ground Combat Systems contract. It called for collaboration between software and reliability subject matter experts to take appropriate steps to include software into the reliability case for the system. I also managed to obtain one fulltime equivalent work year of SWR engineering support to the Program. It was like planting a seed and the fruits of this labor are yet to be realized but progress has been made.

AB Efficient statistical techniques for designing and analyzing experiments are often misunderstood or underutilized, despite possessing great potential when well-informed decision-making and significant cost-savings are desired. Destructive testing with binary response data is a 'worst-case' scenario with regards to cost and efficiency; however, in armaments engineering (especially with explosives, energetic mixes, propellants, pyrotechnics, and other one-shot devices) binary response data is often all that is available. This paper illustrates modern methods and best-practices to employ when dealing with these types of analyses, and contrasts two very different types of testing strategies applied to the munitions used in training and battle by the Warfighter.
First, we introduce the topic of test design and experimentation. To motivate the subject and illustrate some basic aspects of sensitivity testing, we present an example common to the general public: impact-resistant cases for smart-phones.
Next, we elaborate on some of the finer details of Logit Analysis/Binary Logistic Regression and Generalized Linear Models (GLM), while highlighting some of the mathematical underpinnings inherent in these methods.
An overview of testing strategies follows, which compares some of the different methods available for data generation. These methods can be roughly divided into two groups - those dealing with pre-manufactured test samples, and those where sequential testing is an option. Sequential tests are generally applicable when the stress level of interest is adjustable during the test's execution, which, with regard to sample size, allows for a more efficient test.
Then we detail two recent successful examples in armament munitions testing: one where sequential testing was not possible (9mm ammunition propellant critical threshold development), and one where sequential testing was utilized (NMT - Networked Munition Technology).
Finally, we discuss some best-practices, limitations, and rules-of-thumb to be mindful of when considering these methods for different applications.

AB Crevasse initiation is linked to strain rates that range over three orders of magnitude (0.001 and 0.163 a(-1)) as a result of the temperature-dependent nonlinear rheological properties of ice and from water and debris inclusions. Here we discuss a small cold glacier that contains buried crevasses at and near an ice divide. Surface-conformable stratigraphy, the glacier's small size, and cold temperatures argue for limited rheological variability at this site. Surface ice-flow velocities of (1.2-15.5) +/- 0.472 m a(-1) imply classic saddle flow surrounding the ice divide. Numerical models that incorporate field-observed boundary conditions suggest extensional strain rates of 0.003-0.015 a(-1), which fall within the published estimates required for crevasse initiation. The occurrence of one crevasse beginning at 50 m depth that appears to penetrate close to the bed suggests that it formed at depth. Field data and numerical models indicate that a higher interior stress at this crevasse location may be associated with steep convex bed topography; however, the dynamics that caused its formation are not entirely clear.

AB Dynamic ice models use stress tensor to describe the forces arising from internal ice friction. The model stress values are typically one to two magnitudes smaller than values measured by stressmeters deployed on ice floes. The synthesis of the pack-ice stress state from the measurements has been complicated by the peaky character of stress records, and the means to connect them with spatial stress distribution of the floe system have been lacking. Here a reanalysis of Arctic Sea Ice Mechanics Initiative (SIMI) data is made in terms of extreme value statistics. The basic quantity is the maximum stress observed during a time period. The records exhibit self-affine scaling. The statistics are then determined by two parameters, the Hurst exponent H and a reference stress level. Similar analysis is possible for the kinematic data. This establishes the comparability of stress records with each other and with kinematic records. The results suggest that the exponent is related to the stress state of the regional floe system, while the stress level is determined by local floe characteristics. Based on this a characterization of spatial distribution of pack-ice stresses is given.

AB The high cost of titanium has historically prevented widespread use in military ground vehicles. Two strategies to make this material more cost effective and viable are to reduce the cost of titanium armors or to improve the ballistic performance of titanium and reduce the amount of material required. This paper investigates the latter strategy. Mixtures of titanium powders and TiO2 particles were employed as starting materials and consolidated by spark plasma sintering (SPS) and hot extrusion. The content of TiO2 particles was 0 similar to 1.5% of the mass mixture. Solidification of oxygen atoms (from TiO2 particles) into Ti matrix occurred at 1073K for 1800 seconds in a vacuum. Tensile testing showed that Tensile Strength (TS) and Yield Strength (YS) increased in proportion to TiO2 content but elongation decreased slightly with increased TiO2 content. Extruded pure Ti powder material with 1.5% TiO2 particles produced 1040 MPa TS, 902 MPa YS and 25.1% elongation when tested. When using Ti-6Al-4V (Ti-64) alloy powders with 0.5% TiO2 particles, the final extruded Ti-64 powder bars with oxygen solid solution showed 1226 MPa TS and 22.7% elongation. Initial ballistic evaluation showed the Ti-64 powder bars with 0.5% TiO2 particles yielded a marked improvement over the conventionally rolled Ti-64 alloy plate.

In this paper, we describe batch experiments where samples of three Hawaiian acidic upland soils (collected from western Oahu, Hawaii) were equilibrated for 16 h with simulated seawaters, ranging from 0.25-25 g L-1 (or ppT) of total salt, and then washed three times with 20 mu S cm(-1) solutions containing dilute concentration of NaCl (approx. 0.01 g.L-1) to simulate rainfall events. Solution data showed that the exchangeable sodium (ExNa) loads were high on all soils. While much of this ExNa was lixiviated with the rainwater washes, the soil exhibited significant remaining exchangeable sodium percentages (ESP). Consequences of the residual ESP after intensive washings were exhibited in the enhanced dispersiveness (i.e., increased settling time) of the soil colloids. In balance of the continuous sea spray and lower rainfall of the site, it is likely that high salt, high sodium effects would be manifested for extended periods of time in these soils.

AB We have fabricated prototype frequency tripled Nd:YAG lasers using 808nm Vertical Cavity Surface emitting laser (VCSEL) arrays for end-pumping. The passively Q-switched Nd:YAG laser generated 15mJ pulses with a duration of 2-4 ns. Used as a source for third harmonic generation, the laser produced in excess of 2mJ at 355nm. Of particular concern was the impact of temperature variation on conversion efficiency, which included effects for both the source laser and non-linear crystals. Various solutions to the temperature effects were explored to enable operation of the frequency tripled laser over a wide temperature range.

AB The light-harvesting and charge-transfer abilities of Photosystem I (PSI) have generated interest in the development of this system for alternative energy production and energy conversion. We describe multi-scale computational approaches that were used to study electron transfer at the PSI-biological and inorganic interfaces and to model this large protein complex. Our work in the development of an all molecular dynamics model of the PSI monomer is shown and compared to the published experimental and ONIOM optimized models with differences noted in protein and ligand structure, electron branch characterization, and ionization and orbital potentials in the P700 chlorophylls. Differences between the docking of cytochrome c(6) and plastocyanin to PSI using established docking algorithms and molecular dynamics are described. Finally, dipole calculations, luminal surface hydropathicity and polarity characterization were used to predict improvements in surface-assembled monolayer design.

AB Strategies to enhance the already established doublet chemotherapy regimen for lung cancer have been investigated for more than 20 years. Initially, the concept was to administer chemotherapy drugs locally to the tumor site for efficient diffusion through passive transport within the tumor. Recent advances have enhanced the diffusion of pharmaceuticals through active transport by using pharmaceuticals designed to target the genome of tumors. In the present study, five patients with non-small cell lung cancer epidermal growth factor receptor (EGFR) negative stage IIIa-IV International Union Against Cancer 7 (UICC-7), and with Eastern Cooperative Oncology Group (ECOG) 2 scores were administered platinum-based doublet chemotherapy using combined intratumoral-regional and intravenous route of administration. Cisplatin analogues were injected at 0.5%-1% concentration within the tumor lesion and proven malignant lymph nodes according to pretreatment histological/cytological results and the concentration of systemic infusion was decreased to 70% of a standard protocol. This combined intravenous plus intratumoral-regional chemotherapy is used as a first line therapy on this short series of patients. To the best of our knowledge this is the first report of direct treatment of involved lymph nodes with cisplatin by endobronchial ultrasound drug delivery with a needle without any adverse effects. The initial overall survival and local response are suggestive of a better efficacy compared to established doublet cisplatin-based systemic chemotherapy in (higher) standard concentrations alone according to the UICC 7 database expected survival. An extensive search of the literature was performed to gather information of previously published literature of intratumoral chemo-drug administration and formulation for this treatment modality. Our study shows a favorable local response, more than a 50% reduction, for a massive tumor mass after administration of five sessions of intratumoral chemotherapy plus two cycles of low-dose intravenous chemotherapy according to our protocol. These encouraging results (even in very sick ECOG 2 patients with central obstructive non-small cell lung cancer having a worse prognosis and quality of life than a non-small cell lung cancer in ECOG 0 of the same tumor node metastasis [TNM]-stage without central obstruction) for a chemotherapy-only protocol that differs from conventional cisplatin-based doublet chemotherapy by the route, target site, and dose paves the way for broader applications of this technique. Finally, future perspectives of this treatment and pharmaceutical design for intratumoral administration are presented.

AB Certain porous silicon (PS) structures have demonstrated energetic characteristics when mixed with an appropriate oxidizer [1-4]. However, limited studies on the effect of PS structure on its combustion have been performed. This work investigates how various material properties of PS films; surface area, porosity and pore size, affect the combustion process. With pore sizes in the range of 2.6-5.2 nm and surface area reaching over 900 m(2)/g, these materials are capable of considerably fast reactions. Combustion characterization is performed through high speed imaging at a rate of 930,000 frames per second. Propagation speeds in the current study range from 300 - 1950 m/s, and some relationships between the pore characteristics and the propagation velocity are observed.

AB We used measurements of radar-detected stratigraphy, surface ice-flow velocities and accumulation rates to investigate relationships between local valley-glacier and regional ice-sheet dynamics in and around the Schmidt Hills, Pensacola Mountains, Antarctica. Ground-penetrating radar profiles were collected perpendicular to the long axis of the Schmidt Hills and the margin of Foundation Ice Stream (FIS). Within the valley confines, the glacier consists of blue ice, and profiles show internal stratigraphy dipping steeply toward the nunataks and truncated at the present-day ablation surface. Below the valley confines, the blue ice is overlain by firn. Data show that upward-progressing overlap of actively accumulating firn onto valley-glacier ice is slightly less than ice flow out of the valleys over the past similar to 1200 years. The apparent slightly negative mass balance (-0.25 cm a(-1)) suggests that ice-margin elevations in the Schmidt Hills may have lowered over this time period, even without a change in the surface elevation of FIS. Results suggest that (1) mass-balance gradients between local valley glaciers and regional ice sheets should be considered when using local information to estimate regional ice surface elevation changes; and (2) interpretation of shallow ice structures imaged with radar can provide information about local ice elevation changes and stability.

AB One of the most scrutinized contemporary techniques for geospatial data collection and production is crowdsourcing. This inverts the traditional top-down geospatial data production and distribution methods by emphasizing on the participation of the end user or community. The technique has been shown to be particularly useful in the domain of accessibility mapping, where it can augment traditional mapping methods and systems by providing information about transitory obstacles in the built environment. This research paper presents details of techniques and applications of crowdsourcing and related methods for improving the presence of transitory obstacles in accessibility mapping systems. The obstacles are very difficult to incorporate with any other traditional mapping workflow, since they typically appear in an unplanned manner and disappear just as quickly. Nevertheless, these obstacles present a major impediment to navigating an unfamiliar environment. Fortunately, these obstacles can be reported, defined, and captured through a variety of crowdsourcing techniques, including gazetteer-based geoparsing and active social media harvesting, and then referenced in a crowdsourced mapping system. These techniques are presented, along with context from research in tactile cartography and geo-enabled accessibility systems.

AB Four interlaboratory tests were designed to evaluate the performance of match criteria for forensic comparisons of elemental composition of glass by mu-XRF, solution nebulization SN-ICP-MS, LA-ICP-OES and LA-ICP-MS. A total of 24 analysts in 18 laboratories participated in the tests. Glass specimens were selected to study the capabilities of the techniques to discriminate glass produced in the same manufacturing plant at different time intervals and to associate samples that originated from a single source. The assessment of the effectiveness of several match criteria included: confidence interval (+6s, +5s, +4s, +3s, +2s), modified confidence interval, t-test, range overlap, and Hotelling's T-2. Error rates are reported for each of these criteria. Recommended match criteria were those found to produce the lowest combinations of type 1 and type 2 error rates. Performance of the studied match criteria was dependent on the homogeneity of the glass sources, the repeatability between analytical measurements, and the number of elements that were measured. The best results for mu-XRF data were obtained using spectral overlay followed by a +/-3s confidence interval or range overlap. For ICP-based measurements, a wider match criterion, such as a modified confidence interval based on a fixed minimum relative standard deviation (+/-4s, > 3-5% RSD), is recommended due to the inherent precision of those methods (typically < 1-5% RSD) and the greater number of elements measured. Glass samples that were manufactured in different plants, or at the same plant weeks or months apart, were readily differentiated by elemental composition when analyzed by these sensitive methods.

AB It is known that the spin-transfer torque (STT) effect provides a new method of manipulation of magnetization in nano-scale devices. According to the STT effect, bias DC current traversing magnetic multilayers can transfer angular magnetic moments from one layer to another, which can give rise to microwave dynamics of magnetization in the layer. However, it is clear that an inverse effect is also possible. This inverse effect leads to the so-called spin-torque diode effect, first originally observed experimentally in 2005. The spin-torque diode effect is a rectification effect of the input microwave current in a magnetoresistive junction. In this case, the resonance oscillations of the junction resistance can mix with the oscillations of the input microwave current and produce a large enough output DC voltage across the junction. The devices which utilize this effect are called the spin-torque microwave detectors (STMD). In this chapter, we review the general properties of STMDs and consider the performance of a STMD in two different dynamic regimes of detector operation: in the well-known traditional in-plane regime of STMD operation and in the recently discovered novel out-of-plane regime of STMD operation. We analyze the performance of a STMD and consider the typical applications for such detectors in both regimes.

AB High fidelity treatments of the generation and propagation of seismic waves in naturally occurring granular materials is becoming more practical given recent advancements in our ability to model complex particle shapes and their mechanical interaction. Of particular interest are the grain-scale processes that are activated by impact events and the characteristics of force transmission through grain contacts. To address this issue, we have developed a physics based approach that involves laboratory experiments to quantify the dynamic contact and impact behavior of granular materials and incorporation of the observed behavior indiscrete element models.
The dynamic experiments do not involve particle damage and emphasis is placed on measured values of contact stiffness and frictional loss. The normal stiffness observed in dynamic contact experiments at low frequencies (e.g., 10 Hz) are shown to be in good agreement with quasistatic experiments on quartz sand. The results of impact experiments - which involve moderate to extensive levels of particle damage - are presented for several types of naturally occurring granular materials (several quartz sands, magnesite and calcium carbonate ooids). Implementation of the experimental findings in discrete element models is discussed and the results of impact simulations involving up to 5 x 10(5) grains are presented.

AB The application of guided waves to interrogate remote areas of structural components has been researched extensively in characterizing damage. However, there exists a sparsity of work in using piezoelectric transducer-generated guided waves as a method of assessing stress intensity factors (SIF). This quantitative information enables accurate estimation of the remaining life of metallic structures exhibiting cracks, such as military and commercial transport vehicles. The proposed full wavefield approach, based on 3D laser vibrometry and piezoelectric transducer-generated guided waves, provides a practical means for estimation of dynamic stress intensity factors (DSIF) through local strain energy mapping via the J-integral. Strain energies and traction vectors can be conveniently estimated from wavefield data recorded using 3D laser vibrometry, through interpolation and subsequent spatial differentiation of the response field. Upon estimation of the J-integral, it is possible to obtain the corresponding DSIF terms. For this study, the experimental test matrix consists of aluminum plates with manufactured defects representing canonical elliptical crack geometries under uniaxial tension that are excited by surface mounted piezoelectric actuators. The defects' major to minor axes ratios vary from unity to approximately 133. Finite element simulations are compared to experimental results and the relative magnitudes of the J-integrals are examined.

The method is adapted from optical coherence-domain reflectometry (OCDR) which is widely used today in optical coherence tomography (OCT) for medical applications. The paper discusses the coherence multiplexing technique as applied to SAW RFID. A broadband white Gaussian noise source is used as the interrogation signal and one of the major advantages is the large signal dynamic range obtained. A prototype transceiver system was built at 915MHz and used for wireless interrogation of SAW tags. The signal processing technique is discussed and the results of wireless multiplexing of four RFID SAW tags are shown.

AB The imperiled Williams' Crayfish, Orconectes williamsi Fitzpatrick, 1966 is endemic to southwestern Missouri and northwestern Arkansas, U.S.A., an area experiencing rapid urbanization and other land use changes. Populations of O. williamsi in two small streams were studied for 26 months to describe annual reproductive cycles, and gather information about fecundity, sex ratio, size at maturity, size-class structure, and growth. We captured a monthly average of more than 120 O. williamsi from each of the two study populations. The life history of O. williamsi appeared generally similar to what has been reported for several other stream-dwelling species of Orconectes. Breeding season occurred in mid to late autumn and perhaps into early winter. Egg brooding occurred during late winter and early spring, although it was difficult to locate females carrying eggs or hatchlings. Young of year first appeared in samples during May and June. We estimated that these populations of O. williamsi contained 3 or 4 size-classes; smaller O. williamsi grew faster than larger individuals and the mean specific growth rate was about 2% per day during summer. Life history information presented herein will be important if expected future conservation efforts are required.

AB The objectives of this review are to assess the current state of hypertonic saline as a prehospital resuscitation fluid in hypotensive trauma patients, particularly after the 3 major Resuscitation Outcomes Consortium trauma trials in the US and Canada were halted due to futility. Hemorrhage and traumatic brain injury are the leading causes of death in both military and civilian populations. Prehospital fluid resuscitation remains controversial in civilian trauma, but small-volume resuscitation with hypertonic fluids is of utility in military scenarios with prolonged or delayed evacuation times. A large body of pre-clinical and clinical literature has accumulated over the past 30 years on the hemodynamic and, most recently, the anti-inflammatory properties of hypertonic saline, alone or with dextran-70. This review assesses the current state of hypertonic fluid resuscitation in the aftermath of the failed Resuscitation Outcomes Consortium trials.

Results showed that RoboLeader's level of autonomy had a significant impact of participants concurrent target detection task. Participants detected more targets in the Semi-Auto and Full-Auto conditions than in the Manual condition. Participants reported significantly higher workload in the Manual condition than in the two RoboLeader conditions (Semi-Auto and Full-Auto). Operator spatial ability also had a significant impact on target detection and situation awareness performance measures.

AB Long-lived nuclear excited states (isomers) have proven important to understanding nuclear structure. With some isomers having half-lives of decades or longer, and intrinsic energy densities reaching 10(12) J/kg, they have also been suggested for a wide range of applications. The ability to effectively transfer a population of nuclei from an isomer to shorter-lived levels will determine the feasibility of any applications. Here is described a first demonstration of the induced depletion of a population of the 438 year isomer of Ag-108 to its 2.38 min ground state, using 6 MeV bremsstrahlung from a modified medical electron linac. The experiment suggests refinements to be implemented in the future and how a similar approach might be applied to study induced depletion of the 1200 year isomer of Ho-166.

AB Spinal cord injury (SCI) often affects a person's ability to perform critical activities of daily living and can negatively affect his or her quality of life. Assistive technology aims to bridge this gap in order to augment function and increase independence. It is critical to involve consumers in the design and evaluation process as new technologies such as brain-computer interfaces (BCIs) are developed. In a survey study of 57 veterans with SCI participating in the 2010 National Veterans Wheelchair Games, we found that restoration of bladder and bowel control, walking, and arm and hand function (tetraplegia only) were all high priorities for improving quality of life. Many of the participants had not used or heard of some currently available technologies designed to improve function or the ability to interact with their environment. The majority of participants in this study were interested in using a BCI, particularly for controlling functional electrical stimulation to restore lost function. Independent operation was considered to be the most important design criteria. Interestingly, many participants reported that they would consider surgery to implant a BCI even though non-invasiveness was a high-priority design requirement. This survey demonstrates the interest of individuals with SCI in receiving and contributing to the design of BCIs.

AB Doped semiconductor nanocrystals offer great potential for microelectronics and integrated optoelectronics. Nanocrystal based technology is promising for several fields of technology such as thin conducting films, light emitting devices, tunable lasers, transistors, photovoltaics, and less harmful alternatives to toxic fluorescent dyes for application in bio-imaging, to name a few, While properties of nanocrystals are tunable through their size, considerable research is underway to explore the influence of dopants on the properties of semiconductor nanocrystals. The introduction of dopants has been elusive for these confined structures due to their nanoscale sizes as well as the possibility of making them degenerate even with the addition of very small quantities of the dopant. Here, we present a facile, low-cost procedure that we have developed for the synthesis of non-degenerate doped semiconductor nanocrystals and study their properties.

AB Purpose: Oxygen consumption (VO2; mLO(2)/kg/min), gait efficiency (GE; mlO(2)/kg/m) and heart rate (HR; beats per minute) are measures of physiological gait performance. However, the collection device, procedures for data normalization, and biological factors can affect measurement variability. The purpose of this study was to determine the test- retest reliability and minimum detectable change (MDC) for VO2, GE, and HR with the K4b(2) at submaximal walking speeds in healthy young adults. A second purpose was to determine if net measures improved reproducibility. Method: Twenty- two participants completed 2 identical treadmill tests on separate days at submaximal walking speeds from 0.71 m/s to 1.65 m/s. Results: Intraclass correlation coefficient (ICC) values for gross VO2, gross GE, and HR were greater than.85 for all walking speeds. Associated MDC values were approximately 7% to 10% for gross VO2 and GE, and approximately 9% to 12% for HR. ICC values for resting VO2 were lower, with MDC values approaching 25%. Subtracting out resting values to derive net VO2 and GE values produced ICC values below. 76 for the 2 slowest speeds but ICC values greater than.83 for the faster speeds. MDC values for net VO2 and GE were up to 20% for the slowest speeds. Conclusions: The results demonstrate metabolic cost can be assessed reliably using the K4b(2) during submaximal walking and that gross measures are more reliable than net measures. Furthermore, changes at self- selected speeds exceeding 1.0 mLO(2)/kg/min in gross VO2 and 0.01 mLO(2)/kg/m in gross GE can be considered a true change in walking performance.

AB Since power devices such as DMOSFETs will operate at higher temperatures with accelerated degradation mechanisms, it is essential to understand the effects of typical operating conditions for power electronics applications. We have found that SiC MOSFETs when gate-biased at 150 degrees C show an increasing charge pumping current over time, suggesting that interface traps (or perhaps near-interface oxide traps) are being created under these conditions. This trapping increase occurs slightly above linear-with-log-time and mimics previously observed threshold voltage instabilities, though a causal relationship has not yet been determined. We found the charge trapping after 104 s of BTS increased at a rate of 1x10(11) cm(-2)/dec for NBTS (-3 MV/cm), 0.7x10(11) cm(-2)/dec for PBTS (3 MV/cm), and 0.3x10(11) cm(-2)/dec when grounded. The observed increase in charge trapping has negative implications for the long term stability and reliability of SiC MOS devices under operating conditions.

AB Although high-temperature measurements show a dramatic reduction in the bias-temperature stress-induced threshold-voltage instability of present state-of-the-art devices, a more thorough test methodology shows that several different conclusions may actually be drawn. The particular conclusion depends on the specific post-BTS measurement technique employed. Immediate room-temperature measurements suggest that significant oxide-trap activation may still be occurring. A significant, yet rapid, post-BTS recovery is observed as well. These results underline the importance of making both high-temperature and room-temperature measurements, as a function of stress and recovery time, to better ensure that the full effect of the BTS is observed. Initial AC BTS results suggest a similar level of device degradation as occurs from a DC BTS.

ID VOLTAGE SIC DEVICES
AB The multiple-zone junction termination extension (MJTE) is a widely used SiC edge termination technique that reduces sensitivity to implantation dose variations. It is typically implemented in multiple lithography and implantation events. To reduce process complexity, cycle time, and cost, a single photolithography/implantation (P/I) MJTE technique was developed and diodes with 3-zone and 120-zone JTEs were fabricated on the same wafer. Here, the process tolerance of the single (P/I) MJTE technique is evaluated by performing CCD monitored blocking voltage measurements on diodes from the same wafer with the 3-zone and 120-zone single (P/I) JTE. The 3-zone JTE diodes exhibited catastrophic localized avalanches at the interface between the 2nd and 3rd zones due to abrupt zone transitions. Diodes with the smooth transitioning 120-zone JTE exhibited no CCD detectable avalanches in their JTE regions up to the testing limit of 12 kV. Under thick dielectric (deposited for on-wafer diode interconnection), diodes with the single P/I 3-zone JTE failed due to significant loss of high-voltage capability, while their 120-zone JTE diode counterparts were minimally affected. Overall, the single (P/I) 120-zone JTE provides a process-tolerant and robust single P/I edge termination at no additional fabrication labor.

DE PiN diode; high voltage; silicon carbide; carrier lifetime; high

AB In this work, we report our recently developed 16 kV, 1 cm(2), 4H-SiC PiN diode results. The SiC PiN diode was built on a 120 mu m, 2x10(14)/cm(3) doped n-type SiC drift layer with a device active area of 0.5175 cm(2). Forward conduction of the PiN diode was characterized at temperatures from 20 degrees C to 200 degrees C. At high injection-current density (J(F)) of 350 similar to 400 A/cm(2), the differential on-resistance (R-ON,R-diff) of the SiC PiN diode decreased from 6.08 m Omega.cm(2) at 20 degrees C to 5.12 m Omega.cm(2) at 200 degrees C, resulting in a very small average temperature coefficient of -5.33 mu Omega.cm(2)/degrees C, while the forward voltage drop (V-F) at 100 A/cm(2) reduced from 4.77 V at 20 degrees C to 4.17 V at 200 degrees C. This is due to an increasing high-level carrier lifetime with an increase in temperature, resulting in reduced forward voltage drop. We also observed lower R-ON,R-diff at higher injection-current densities, suggesting that a higher carrier lifetime is needed in this lightly doped n-type SiC thick epi-layer in order to achieve full conductivity modulation. The anode to cathode reverse blocking leakage current was measured as 0.9 mu A at 16 kV at room temperature.

AB A necessity for the successful commercialization of SiC power devices is their long term reliability under the switching conditions encountered in the field. Normally-ON 1200 V SiC JFETs were stressed in repetitive hard-switching conditions to determine their fault handling capabilities. The switching pulses were generated from an RLC circuit, where energy initially stored in capacitors discharges through the JFET into a resistive load. The hard-switching included one million repetitive pulsed hard-switching events at 25 degrees C from a drain blocking-voltage of 600 V to an on-state current of 67 A, and an additional one million 600-V/63-A pulsed hard-switching events at 150 degrees C. The JFET conduction and blocking-voltage characteristics are virtually unchanged after over two million hard switching events proving the devices are reliable for handling high surge-current faults like those encountered in bidirectional circuit breaker applications.

AB In this paper, we report our recently developed 1 cm(2), 15 kV SiC p-GTO with an extremely low differential on-resistance (R-ON,R-diff) of 4.08 m Omega.cm(2) at a high injection-current density (J(AK)) of 600 similar to 710 A/cm(2). The 15 kV SiC p-GTO was built on a 120 mu m, 2x10(14)/cm(3) doped p-type SiC drift layer with a device active area of 0.521 cm(2). Forward conduction of the 15 kV SiC p-GTO was characterized at 20 degrees C and 200 degrees C. Over this temperature range, the R-ON,R-diff at J(AK) of 600 similar to 710 A/cm(2) decreased from 4.08 m Omega.cm(2) at 20 degrees C to 3.45 m Omega.cm(2) at J(AK) of 600 similar to 680 A/cm(2) at 200 degrees C. The gate to cathode blocking voltage (V-GK) was measured using a customized high-voltage test setup. The leakage current at a V-GK of 15 kV were measured 0.25 mu A and 0.41 mu A at 20 degrees C and 200 degrees C respectively.

ID AD HOC NETWORKS; SECURITY ISSUES
AB Mobile Ad Hoc Networks (MANETs) have been widely used in commercial and tactical domains. MANETs commonly demand a robust, diverse, energy-efficient, and resilient communication and computing infrastructure, enabling network-centric operation with minimal downtime. MANETs face security risks and energy consumption. However, conducting cyber attack monitoring and detection in a MANET becomes a challenging issue because of limited resources and its infrastructureless network environment. To address this issue, we develop both lossless and lossy aggregation techniques to reduce the energy cost in information transition and bandwidth consumption while preserving the desired detection accuracy. In particular, we develop two lossless aggregation techniques: compression-based and event-based aggregation and develop a lossy aggregation technique: feature-based aggregation. We conduct real-world experiments and simulation study to evaluate the effectiveness of our proposed data aggregation techniques in terms of the energy consumption and detection accuracy.

AB This paper presents a microfluidic electrical impedance flow cytometer (FC) for identifying the differentiation state of single stem cells. This device is comprised of a novel dual micropore design, which not only enhances the processing throughput, but also allows the associated electrodes to be used as a reference for one another. A signal processing algorithm, based on the support vector machine (SVM) theory, and a data classification method were developed to automate the identification of sample types and cell differentiation state based on measured impedance values. The device itself was fabricated using a combination of standard and soft lithography techniques to generate a PDMS-gold electrode construct. Experimental testing with non-biological particles and mouse embryonic carcinoma cells (P19, undifferentiated and differentiated) was carried out using a range of excitation frequencies. The effects of the frequency and the interrogation parameters on sample identification performance were investigated. It was found that the real and imaginary part of the detected impedance signal were adequate for distinguishing the undifferentiated P19 cells from non-biological polystyrene beads at all tested frequencies. A higher frequency and an opacity index were required to resolve the undifferentiated and differentiated P19 cells by capturing capacitive changes in electrophysiological properties arising from differentiation. The experimental results demonstrated salient accuracy of the device and algorithm, and established its feasibility for non-invasive, label-free identification of the differentiation state of the stem cells.

AB Problems of poverty, poor health, and incarceration are unevenly distributed among racial and ethnic minorities in the United States. We argue that this is due, in part, to the ascendance of United States-style neoliberalism, a prevailing political and economic doctrine that shapes social policy, including public health and anti-poverty intervention strategies. Public health research most often associates inequalities in health outcomes, poverty, and incarceration with individual and cultural risk factors. Contextual links to structural inequality and the neoliberal doctrine animating state-sanctioned interventions are given less attention. The interrelationships among these are not clear in the extant literature. Less is known about public health and incarceration. Thus, the authors describe the linkages between neoliberalism, public health, and criminal justice outcomes. We suggest that neoliberalism exacerbates racial disparities in health, poverty, and incarceration in the United States. We conclude by calling for a new direction in public health research that advances a pro-poor public health agenda to improve the general well-being of disadvantaged groups.

AB Surface enhanced Raman scattering (SERS) is rapidly emerging as a sensitive transduction platform for the trace detection of chemical and biological analytes. A critical challenge that needs to be addressed to propel this technique into real world applications is the poor chemical selectivity of the existing SERS substrates. In this communication, we demonstrate a novel biomimetic approach to enhance the selectivity of plasmonic nanostructures to target chemical analytes. In particular, we demonstrate that material-binding peptides, identified through phage-display, serve as recognition elements for selective capture of target chemical species from a complex chemical mixture. As a proof of concept, we show that a nitroaromatic explosive molecule, trinitrotoluene (TNT), can be detected down to 100 pM concentration even in a complex organic chemical mixture. This ultrasensitive and selective detection is enabled by TNT-binding peptides appended to gold nanorods, which serve as selective SERS media. To the best of our knowledge, this is the first demonstration of a biomimetic SERS substrate facilitating selective and sensitive detection of a target chemical analyte in the presence of numerous unknown interfering species.

AB Direct plating on solid agar media has been widely used in microbiology laboratories for presumptive-positive pathogen detection, although it is often subjective and labour-intensive. Rainbow agar is a selective and differential chromogenic medium used to isolate pathogenic Escherichia coli (E. coli) strains. However, it is challenging to differentiate colonies of the six representative pathogenic non-0157 Shiga-toxin producing E. coli (STEC) serogroups (026, 045, 0103, 0111, 0121 and 0145) on Rainbow agar due to the phenotypic differences and the presence of background microflora. Therefore, there is a need for a method or technology to objectively, rapidly and accurately perform high-throughput screening of non-0157 STEC colonies on agar plates. In this paper, we report the development of a visible-near infrared hyperspectral imaging technique and prediction model for differentiating colony types of the six non-0157 STEC serogroups in spread plates of pure cultures inoculated on Rainbow agar. The prediction model was based on supervised linear classification of factor scores obtained by principal component analysis (PCA). Both PCA-MD (Mahalanobis distance) and PCA-kNN (k-nearest neighbour) classifiers were used for model development. From the 24 hyperspectral images measured from two replicates, 51,173 spectral samples were collected from 1421 colonies. Chemometric preprocessing methods and other operating parameters, such as scatter correction, first derivative, moving average, sample size and number of principal components (PCs), were compared with a classification and regression tree (CART) method, configured as a classification tree and followed by brute-force searching from candidates selected by the CART. The number of PCs, scatter correction and moving average were selected as the most important elements to consider before selecting a set of candidate models. Cross-validation (CV), such as hold out and k-fold CV, was used to validate the prediction performance of candidate models. Serogroups 0111 and 0121 consistently showed over 99% classification accuracy regardless of the classification algorithms. However, the classification accuracies of serogroups 026, 045, 0103 and 0145 showed varying results from 84% up to 100%, depending on which preprocessing treatment and prediction model were adopted. The best overall mean classification accuracy of 95.06% was achieved with PCA-kNN (k=3), six PCs, five-pixel sample size defined around each colony centre, standard normal variate and detrending, first derivative with 11-point gaps and moving average with 11-point gaps. Future studies will focus on automating colony segmentation, further improving detection accuracy of the developed models, expanding the spectral library to include background microflora from ground beef and developing prediction models to detect the target bacteria in the presence of background microflora.

AB OBJECTIVE: Drawing on prior occupational choice research on entrepreneurs and self-employed business owners, we examined personality predictors of their occupational business success and work satisfaction.
PARTICIPANTS AND PROCEDURES: A sample of 147 small business owners completed a web-based assessment of 14work-related personality traits - Adaptability, Autonomy, Competitiveness, Dependability, Emotional Resilience, Goal-Setting, Optimism, Persistence, Risk Tolerance, Self-Promotion, Networking, and Tolerance for Financial Insecurity, Work-Based Locus of Control, and Work Drive - and three self-reported indices of business success - revenue growth, profit growth, and income growth - as well as multiple facets of individual satisfaction. Criterion variables included composite business success and overall satisfaction.
RESULTS: Ten traits correlated with business success. The top four personality predictors of success - Goal-Setting, Social Networking, Emotional Resilience, and Work Drive - together accounted for 16% of the variance. Similarly, 12 of 14 personality traits were positively related to overall satisfaction. The top three personality predictors of satisfaction - Optimism, Work-based Locus of Control, and Work Drive - accounted for 29% of the variability in satisfaction. An expectancy analysis revealed that the percent of participants who reported at least a 20% increase in sales and profits the preceding year was 26% versus 54% for individual scoring in the lower and upper third of a personality composite measure.
CONCLUSIONS: Results carry implications for future research, and have direct, practical applications for prospective and current entrepreneurs and self-employed owners of small businesses.

AB Carbon nanotubes (CNTs) have the potential to enhance the strength, toughness, and multifunctional ability of composite materials. However, suitable dispersion and interfacial bonding remain as key challenges. Composites that are formed by reactions with water, like Portland cement concrete and mortar, pose a special challenge for dispersing the inherently hydrophobic nanotubes. The hydration of Portland cement also offers a specific chemical framework for interfacial bonding. In this study, nanoscale silica functional groups are covalently bonded to CNTs to improve their dispersion in water while providing interfacial bond sites for the proposed matrix material. The bond signatures of treated nanotubes are characterized using Fourier transform infrared spectroscopy. In situ dispersion is characterized using cryogenic transmission electron microscopy and point of zero charge (PZC) measurements. At the nanoscale, inter-particle spacing was greatly increased. A slight increase in the PZC after treatment indicates the importance of steric effects in the dispersion mechanism. Overall, results indicate successful functionalization and dramatically improved dispersion stability in water.

AB The Soft Catch Gun at Picatinny Arsenal is regularly used for component testing. Most shots contain accelerometers which record accelerations as a function of time. Statistics of accelerometer data indicate that the muzzle exit accelerations are, on average, higher than tactical firings. For that reason, Soft Catch Gun tests with unusually high accelerations may not be scored for Lot Acceptance Tests (LAT) by some customers. The 95/50 Normal Tolerance Limit (NTL) is proposed as a means of determining which test results should be scored. This paper presents comparisons of Shock Response Spectra (SRS) used for the 95/50 scoring criteria. The paper also provides a Discussion Section outlining some concerns with scoring LAT results based on test results outside of the proposed 95/50 criteria.

AB Colorectal cancer (CRC) is a major burden to healthcare systems worldwide accounting for approximately one million of new cancer cases worldwide. Even though, CRC mortality has decreased over the last 20 years, it remains the third most common cause of cancer-related mortality, accounting for approximately 600,000 deaths in 2008 worldwide. A multitude of risk factors have been linked to CRC, including hereditary factors, environmental factors and inflammatory syndromes affecting the gastrointestinal tract. Recently, various pathogens were added to the growing list of risk factors for a number of common epithelial cancers, but despite the multitude of correlative studies, only suggestions remain about the possible relationship between selected viruses and bacteria of interest and the CRC risk. United States military service members are exposed to various risk factors impacting the incidence of cancer development. These exposures are often different from that of many sectors of the civilian population. Thereby, cancer risk identification, screening and early detection are imperative for both the military health care beneficiaries and the population as a whole. In this review, we will focus on several pathogens and their potential roles in development of CRC, highlighting the clinical trials evaluating this correlation and provide our personal opinion about the importance of risk reduction, health promotion and disease prevention for military health care beneficiaries.

AB Laser illumination makes it possible to perform high resolution imaging when ambient light level is insufficient to overcome camera noise. The relatively long coherence length of most lasers, however, causes coherent speckle in the camera image plane, which can result in a significant decrease of the image quality and the maximum achievable target identification range. We characterized several types of NIR and SWIR laser diode illumination sources, with emphasis placed on measuring the properties of coherent speckle observed in the camera image plane. Image plane speckle contrast was measured by illuminating the imaged Lambertian surface with single-mode laser, multi-mode laser, wide-stripe laser with two active junctions and broad-band emission, and NIR and SWIR vertical cavity surface emitting laser (VCSEL) arrays. The impact of various imaging system parameters, including pixel size, imaging lens focal length, F-number, and IFOV on the contrast and characteristic size of the speckle intensity distribution were determined. Speckle contrast dependence on the polarization properties of various reflecting surfaces was measured. The reduction of speckle contrast with increasing source spectral width, and increasing size of spatially incoherent VCSEL emitter arrays will be described. We show that a speckle contrast of 5-10% is achievable for a typical long range SWIR imaging system.

AB This is the second paper in a series of two that describe our research in intelligent energy management in a hybrid electric vehicle (HEV). In the first paper, we presented the machine-learning framework ML_EMO_HEV, which was developed for learning the knowledge about energy optimization in an HEV. The framework consists of machine-learning algorithms for predicting driving environments and generating the optimal power split of the HEV system for a given driving environment. In this paper, we present the following three online intelligent energy controllers: 1) IEC_HEV_SISE; 2) IEC_HEV_MISE; and 3) IEC_HEV_MIME. All three online intelligent energy controllers were trained within the machine-learning framework ML_EMO_HEV to generate the best combination of engine power and battery power in real time such that the total fuel consumption over the whole driving cycle is minimized while still meeting the driver's demand and the system constraints, including engine, motor, battery, and generator operation limits. The three online controllers were integrated into the Ford Escape hybrid vehicle model for online performance evaluation. Based on their performances on ten test drive cycles provided by the Powertrain Systems Analysis Toolkit library, we can conclude that the roadway type and traffic congestion level specific machine learning of optimal energy management is effective for in-vehicle energy control. The best controller, IEC_HEV_MISE, trained with the optimal power split generated by the DP optimization algorithm with multiple initial SOC points and single ending point, can provide fuel savings ranging from 5% to 19%. Together, these two papers cover the innovative technologies for modeling power flow, mathematical background of optimization in energy management, and machine-learning algorithms for generating intelligent energy controllers for quasioptimal energy flow in a power-split HEV.

AB Efficient methods for solving linear algebraic equations are crucial to creating fast and accurate numerical simulations in many applications. In this paper, an algebraic multigrid (AMG) method, which combines the classical coarsening scheme by [19] with an energy-minimizing interpolation algorithm by [26], is employed and tested for subsurface water simulations. Based on numerical tests using real field data, our results suggest that the energy-minimizing algebraic multigrid method is efficient and, more importantly, very robust.

AB We evaluated the Minnesota Multiphasic Personality Inventory-Second Edition (MMPI-2) Response Bias Scale (RBS). Archival data from 83 individuals who were referred for neuropsychological assessment with no formal diagnosis (n=10), following a known or suspected traumatic brain injury (n=36), with a psychiatric diagnosis (n=20), or with a history of both trauma and a psychiatric condition (n=17) were retrieved. The criteria for malingered neurocognitive dysfunction (MNCD) were applied, and two groups of participants were formed: poor effort (n=15) and genuine responders (n=68). Consistent with previous studies, the difference in scores between groups was greatest for the RBS (d=2.44), followed by two established MMPI-2 validity scales, F (d=0.25) and K (d=0.23), and strong significant correlations were found between RBS and F (rs=.48) and RBS and K (r=.41). When MNCD group membership was predicted using logistic regression, the RBS failed to add incrementally to F. In a separate regression to predict group membership, K added significantly to the RBS. Receiver-operating curve analysis revealed a nonsignificant area under the curve statistic, and at the ideal cutoff in this sample of >12, specificity was moderate (.79), sensitivity was low (.47), and positive and negative predictive power values at a 13% base rate were .25 and .91, respectively. Although the results of this study require replication because of a number of limitations, this study has made an important first attempt to report RBS classification accuracy statistics for predicting poor effort at a range of base rates.

The resulting interferograms, with superimposed diffractive signals, were recorded using digital means and reproduced using N-slit interferometric calculations. We also show, for the first time, very slight and subtle alterations of the propagating interferograms via the soft insertion of spider web silk fibers into the intra-interferometric path. The experiments were performed at an overall intra-interferometric propagation path length of 7.235 m.

AB We study complex processes whose evolution in time rests on the occurrence of a large and random number of events. The mean time interval between two consecutive critical events is infinite, thereby violating the ergodic condition and activating at the same time a stochastic central limit theorem that supports the hypothesis that the Mittag-Leffler function is a universal property of nature. The time evolution of these complex systems is properly generated by means of fractional differential equations, thus leading to the interpretation of fractional trajectories as the average over many random trajectories each of which satisfies the stochastic central limit theorem and the condition for the Mittag-Leffler universality.

AB This paper compares between the methods of growing carbon nanotubes (CNTs) on diamond substrates and evaluates the quality of the CNTs and the interfacial strength. One potential application for these materials is a heat sink/spreader for high-power electronic devices. The CNTs and diamond substrates have a significantly higher specific thermal conductivity than traditional heat sink/spreader materials making them good replacement candidates. Only limited research has been performed on these CNT/diamond structures and their suitability of different growth methods. This study investigates three potential chemical vapor deposition (CVD) techniques for growing CNTs on diamond: thermal CVD (T-CVD), microwave plasma-enhanced CVD (MPE-CVD), and floating catalyst thermal CVD (FCT-CVD). Scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (TEM) were used to analyze the morphology and topology of the CNTs. Raman spectroscopy was used to assess the quality of the CNTs by determining the I-D/I-G. peak intensity ratios. Additionally, the CNT/diamond samples were sonicated for qualitative comparisons of the durability of the CNT forests. T-CVD provided the largest diameter tubes, with catalysts residing mainly at the CNT/diamond interface. The MPE-CVD process yielded non uniform defective CNTs, and FCT-CVD resulted in the smallest diameter CNTs with catalyst particles imbedded throughout the length of the nanotubes.

AB . In a unique longitudinal study of teen driving, risky driving behaviour and the occurrence of crashes or near crashes are measured prospectively over the first 18 months of licensure. Of scientific interest is relating the two processes and developing a predictor of crashes from previous risky driving behaviour. In this work, we propose two latent class models for relating risky driving behaviour to the occurrence of a crash or near-crash event. The first approach models the binary longitudinal crash or near-crash outcome by using a binary latent variable which depends on risky driving covariates and previous outcomes. A random-effects model introduces heterogeneity among subjects in modelling the mean value of the latent state. The second approach extends the first model to the ordinal case where the latent state is composed of K ordinal classes. Additionally, we discuss an alternative hidden Markov model formulation. Estimation is performed by using the expectationmaximization algorithm and Monte Carlo expectationmaximization. We illustrate the importance of using these latent class modelling approaches through the analysis of the teen driving behaviour.

AB Red abalone (Haliotis rufescens) were assessed inside and outside a "de facto" reserve before fishing, after 3 and then 6 years of fishing. In just 3 years, there was a 65% decline (p < 0.001) in the subtidal and a 78% decline (p < 0.001) in the intertidal abalone populations. Size frequency distributions differed significantly following fishing and there was a sharp decrease in the potential egg production (>72% decline). Before fishing began, the intertidal density at the reserve was 86% greater (p = 0.001) than at a nearby fished site, however after 3 years of fishing there was no difference (p = 0.764). Abalone fishing report cards revealed a 950% increase in local catch once the reserve site was opened, however after just 1.5 years of fishing, catch declined sharply (59%) compared to the previous year. In 3 years, mean abalone catch per hour declined significantly (p < 0.001) from 7.01 (SD 6.14) to 2.44 (SD 1.98) as did abalone catch/picker from 2.83 (SD 0.47) to 2.38 (SD 0.92, p < 0.01). Estimates of illegal take inside the former reserve were 2.5 times greater than the legal catch. We demonstrate that for areas with high value, slow growing species such as red abalone, temporarily opening reserves may lead to density, size structure and egg production similar to heavily fished areas in just 3 years. These results caution against the use of temporal (rotating) reserves for abalone and emphasize the importance of marine spatial planning. (C) 2012 Elsevier Ltd. All rights reserved.

AB Public-private partnerships can serve as an effective mechanism to collectively strengthen community disaster preparedness and critical infrastructure resilience. This process involves multiple intersecting elements, including Federal, State, regional, local, and private-sector stakeholders, each with unique operating conditions and risks within its own environment. The 2010 Dams Sector Exercise Series (DSES-10) represents an example of the type of public-private effort that can lead to enhanced resilience on a regional scale. This paper discusses the findings and outcomes resulting from the DSES-10 effort, including its capstone Regional Resilience Strategy. The strategy was designed to assist public and private stakeholders in the identification of integrated post-disaster recovery solutions with respect to a catastrophic flood event, prioritization of actions to improve regional disaster resilience, and development of sustainable public-private partnerships to enhance planning and multi-jurisdictional coordination in the context of a wide range of potential threats and hazards.

AB Objective: To evaluate factors that are predictive of delayed abdominal closure in patients injured during military conflict.
Design, Setting, and Patients: Seventy-one patients managed with an open abdomen were identified from records at Landstuhl Regional Medical Center from 2005 and 2006. Follow-up data were available from Walter Reed Army Medical Center. Records were reviewed through all echelons of care. Ordinal logistic regression was used to predict delayed abdominal closure.
Results: Patients sustained injury from blunt (n = 2), penetrating (n = 30), and blast (n = 39) mechanisms. The median Injury Severity Score was 25 (interquartile range, 17-34). Abdominal injury was observed in 85% of patients, and 48% underwent a massive transfusion. The median time to transfer to the United States was 5.3 days (interquartile range, 4.3-6.8 days). Abdomens were definitively closed downrange (11%), at Landstuhl Regional Medical Center (33%), or at Walter Reed Army Medical Center (56%). The median time until abdominal closure was 13 days (interquartile range, 4-40 days) in 2005 compared with 4 days (interquartile range, 1-14.5 days) in 2006 (P = .02). The multivariate model identified massive transfusion (odds ratio, 3.9), presence of complications (odds ratio, 5.1), and an injury date in 2005 (odds ratio, 3.4) as independently predictive variables for later abdominal closure.
Conclusions: Massive transfusion, occurrence of complications, and earlier injury date were predictive of delayed abdominal closure in casualties managed with an open abdomen. These data suggest an evolving approach to the management of severely injured combat casualties that involves earlier abdominal closure. JAMA Surg. 2013;148(1):59-64.

THRESHOLD; SNOWDRIFT; SURFACE
AB Historically, there has been considerable interest in establishing the relationship between wind-blown snow flux (Q) and wind speed. By monitoring the drift growth at snow fences in Arctic Alaska during three winters, we computed Q for 36 distinct transport events. Each fence was instrumented with depth sounders to measure deposition rates. The majority of events (31) occurred between November and February, despite winter extending from October to June. On average, five substantial snow deposition events (SDEs) occurred at each fence per winter. The mean flux during SDEs was 0.16, 0.19 and 0.29 kg s(-1) m(-1) at Barrow, Imnavait Creek and Franklin Bluffs, respectively, the differences in Q explained by the different wind regimes at the three sites. To place these flux measurements in perspective, we reviewed all previous experimental values of Q, with special attention to height and time over which the fluxes were measured. The new data help fill a range of wind speeds (12-18 m s(-1)) where prior results have been sparse. Combined, the full data define a diffuse cloud best represented by upper and lower bounding equations Q(U) = 1.3 x 10(-3)W(2.5) and Q(L) =3.3 x10(-9)W(6.5), where W is wind speed (>5 m s(-1)). We suggest that these bounds, rather than a single equation, provide the best way to estimate snow fluxes.

AB Introduction: The purpose of this research is to describe the leading circumstances of military vehicle crashes to guide prioritization and implementation of crash avoidance and/or warning technologies. Methods: A descriptive study using narrative text analysis on 3,944 military vehicle crash narratives. Crash data on drivers, from 2001 to 2006, were assembled from the U.S. Army Combat Readiness/Safety Center. Reviewers collected information on the circumstances of crashes and determined if vehicle technology could have prevented the crash. Results: Nearly 98% of the crashes were nonfatal; 63% occurred in the U.S. and 24% in Iraq. Among crash events where the direction of the impact was recorded, 32% were to the front of the vehicle and 16% involved a vehicle being rear-ended. Rollovers were mentioned in 20% of the narratives. Technology was determined to have the potential to prevent 26% of the crashes, with the forward collision warning system, rear end collision avoidance, emergency brake assistance, and rollover stability control system likely to have the greatest impacts. Conclusions: Some technologies available for civilian vehicles may prevent certain military crash circumstances. Impact on Industry: The results of this research are significant in light of ongoing global military operations that rely on military vehicles. Improving the preventive technology featured on military vehicles may be an effective strategy to reduce the occurrence of military crashes. (C) 2013 National Safety Council and Elsevier Ltd.

AB OBJECTIVE: To evaluate the association of pre-accession physical fitness, as measured by a five-minute step test, with incidence of overuse injuries and outpatient healthcare utilization among male United States (US) Army recruits.
PARTICIPANTS: US Army male trainees who met weight standards and took a pre-accession fitness test.
METHODS: In this prospective cohort study, incidence and outpatient healthcare visits for overuse injuries during the first 90 days of military service were compared between recruits who failed the pre-accession step test with those who passed.
RESULTS: The hazard rate ratio for injury among recruits who failed the fitness test compared to those who passed the test was 1.31 (95% C. I = 1.20-1.44). Among the subset of recruits with at least one medical encounter for an overuse injury, the utilization rate ratio for subjects who failed the fitness test versus those who passed was 1.15 (95% C. I = 1.09-1.22). Other factors associated with increased risk of injury or healthcare utilization include age, body mass index, and smoking history.
CONCLUSIONS: Risk of injury and utilization were associated with fitness test results. These findings may have implications for military accession and training policy as well as for other physically demanding training programs such as police, fire fighters and athletes.

AB Robust host innate immune response to staphylococcal enterotoxin B (SEB) and structurally related superantigens causes toxic shock and various autoimmune diseases. While proinflammatory cytokines are known for mediating SEB-induced toxicity, the role of complement C5a in SEB-mediated shock is less well-understood. An ELISA was developed to measure the complement activation product, C5a, in different murine models of toxic shock. This assay provides easy, quantifiable data for complement activation and its role in various SEB-induced toxic shock models.

AB It is well known that projectiles equipped with liquid payloads experience large destabilizing moments induced by internal motion of the fluid. For some configurations, these moments may lead to catastrophic flight instabilities. This paper explores how payload geometry, fluid spin-up rate, and the magnitude of launch perturbations affect the flight trajectories of projectiles with a liquid payload, including projectile instability. A dynamic simulation model is used in which a projectile rigid-body dynamics representation incorporates liquid moments generated from linearized Navier-Stokes predictions. A novel feature of this simulation is its use of linear filtering within the model, which determines fast- and slow-mode angle-of-attack contributions at each time step to be used in computation of liquid moments. Example cases and Monte Carlo simulations demonstrate how design factors and launch perturbations affect the projectile's tendency to exhibit flight instability. The paper concludes with a summary of advantageous design characteristics that are likely to mitigate the effects of destabilizing liquid moments.

AB Few would argue against the position that spatial cognition involves cognition. Much of spatial cognition research has focused on illuminating the domain-general processes (e.g. attention, memory, or representation) active in this domain-specific field. In this chapter, we suggest that researchers view this domain-general to domain-specific relationship in the opposite direction. In other words, we review spatial cognition research within the context of its utility for understanding domain-general processes. For a cognitive process to be domain-general, it should be evident across a wide variety of domain-specific tasks, including verbal and spatial ones. Yet, the majority of data supporting domain-general models comes from verbal tasks, such as list learning. Thus, we suggest that considering spatial cognition tasks and findings along with those from other domains would enhance our understanding of truly domain-general processing.

AB OBJECTIVE: During interviews with Health Care Specialist military cadre, instructors voiced concern that symptoms associated with attention deficit and hyperactivity disorder (SoADHD) and oppositional defiant disorder (SoODD) were interfering with soldiers' ability to complete training. The purpose of this research was to examine the relationship between SoADHD and SoODD with soldiers' grade point average (GPA), Army Physical Fitness Test (APFT) scores, and musculoskeletal injuries during Health Care Specialist (HCS) Advanced Individual Training (AIT).
METHOD: Participants included 122 soldiers attending HCS training. Participants completed a demographic survey and Barkley and Murphy's ADHD and ODD self-report symptom surveys. Their ADHD and ODD self-report scores were correlated with course performance metrics at the conclusion of their 16 weeks of training.
RESULTS: Pearson Correlation Coefficients revealed a significant negative relationship between ratings on the Oppositional Defiant Disorder scale with soldiers' GPA (p < 0.05), however the relationship was weak accounting for 4% of the variance. No significant findings were noted between SoADHD and GPA, nor were significant relationships found between SoADHD or SoODD with APFT scores or musculoskeletal injuries.
CONCLUSION: Symptoms associated with ADHD and ODD had little impact on the academic and physical performance of soldiers attending HCS training. Implications and future research are explored, in this article.

AB The objective of this study was to describe trends in the diagnostic rates for anxiety disorders (ADs) types in the U.S. military from 2000 to 2009. Data for the numbers of diagnosed cases for the first documented occurrence of ADs during ambulatory visits while serving in the military were obtained from the Defense Medical Epidemiology Database for all active duty service members and examined across branch of service and by gender. Results indicate that Anxiety Not Otherwise Specified (ANOS) was the most frequently diagnosed AD type in each of the 10 years between 2000 and 2009, with an average rate of 0.8 per 100 service members for first service occurrence, followed by PTSD at a rate of 0.5 out of every 100. Starting in 2002, the yearly first occurrence rates of ANDS and PTSD were significantly higher (p < 0.001) compared to each proceeding year, with the same pattern present among males and females separately. The majority of first occurrence AD diagnoses were diagnosed in the Army (47% of Anxiety NOS and 60% of PTSD cases) compared to the other service branches (i.e., Navy, Air Force, and Marines).

AB Visible and infrared video cameras are the most common imaging sensors used for video surveillance systems. Fusing concurrent visible and infrared imageries may further improve the overall detection and tracking performance of a video surveillance system. We performed image fusion using 13 pixel-based image fusion algorithms and examined their effects on the detection and tracking performance of a given target tracker. We identified five fusion methods that produced significantly better performance, three of which also managed to achieve that with a relatively high efficiency.

AB High molecular weight chitin fibers were electrospun in a one-pot process directly from a 1-ethyl-3-methylimidazolium acetate solution of chitin extracted from dried shrimp shell. Such a technology obviates the need not only for the many chemicals and the energy used in industrial isolation of chitin from crustacean shells but also saves the chemicals, energy, and time needed to prepare chitin spinning dopes.

AB A recombinant ricin toxin A-chain 1-33/44-198 vaccine (RVEc (TM)), developed at the United States Army Medical Research Institute of Infectious Diseases as a vaccine candidate, is under investigation in a phase 1 clinical study. To effectively evaluate the immunogenicity of this ricin vaccine and to eliminate the use of radioactive material, an EL4 cell-based colorimetric toxin neutralization activity (TNA) assay using a Cell Titer 96 (R) AQ(ueous) One Solution Cell Proliferation Assay Reagent has been developed, optimized, and applied in the vaccine efficacy studies. The TNA assay measures the protective neutralizing anti-ricin antibodies in animal sera by determining the cell viability after ricin exposure in the assay system and comparing it to a purified mouse polyclonal anti-ricin IgG standard curve. The standard curve of the anti-ricin TNA assay closely fits a four-parameter logistic regression model. The unknown test sample concentration was expressed as mu g/mL, but not the 50% effective concentration (EC50), which was determined by most TNA assays. The neutralizing endpoint titers, not the 50% effective dilution (ED50), of human specimens were measured with the TNA assay in support of the clinical study of the RVEc vaccine. The optimal amount of ricin toxin, EL4 cells, and concentration of standards used in the assay system was established to minimize false-negative and false-positive results of serum specimens from the nonclinical and clinical studies of RVEc. The testing conditions were adjusted to optimize assay performance. The colorimetric TNA assay replaced a radioactive TNA assay previously used in the ricin vaccine studies.

AB Accidents and trauma are the leading cause of hospital admissions and major contributors to mortality in children and adolescents. There are age-specific injury patterns and differences in the clinical presentation of pediatric trauma and treatment both at the scene and in the emergency department can be observed. In general, pediatric trauma-scores to appreciate injury severity are adapted from the adult population.
The most important factor to increase mortality in the severely injured pediatric population is the extent of a concomitant traumatic brain injury (TBI). In addition, the acute trauma-associated coagulopathy, which is triggered multifactorial, is an independent prognostic marker for mortality in severe trauma. The complexity of all currently available trauma-scores for the pediatric population is one reason why these scores are not unequivocal recommended for the early use in pediatric trauma care.
The pediatric BIG-Score was developed to allow an early prognostic stratification for pediatric trauma patients and includes with base excess (BE), INR (International Normalized Ratio) and GCS (Glasgow Coma Scale) relevant prognostic factors for poor outcome.
Early risk stratification is crucial in pediatric trauma due to mortality rates ranging between 9% and 15% and with 50% of all fatalities to occur within the first 24h of hospital admission.

MORTALITY; OUTCOMES; PROGNOSIS
AB Background/Aims: Dysnatremias have been evaluated in many populations and have been found to be significantly associated with mortality. However, this relationship has not been well described in the burn population. Methods: Admissions to the burn center at our institution from January 2003 to December 2008 were examined. Independent variables included gender, age, percentage total body surface area burned (%TBSA), percentage of third-degree burn, inhalation injury, injury severity score (ISS), Acute Kidney Injury Network (AKIN) stage, hypernatremia, and hyponatremia. They were examined via Cox proportional hazard regression models against death. Moderate to severe hypo-and hypernatremia were defined as serum sodium < 130 and > 150 mmol/l, respectively. Results: In 1,969 subjects with a mean age of 36.3 +/- 16.4 years, a median %TBSA of 9 (interquartile range 4-20) and a median ISS of 5 (interquartile range 1-16) hypernatremia occurred in 9.9% (n = 194), while hyponatremia occurred in 6.8% (n = 134) with mortality rates of 33.5 and 13.8%, respectively. Patients without a dysnatremia had a mortality rate of 4.3%. On Cox proportional hazard regression age, %TBSA, ISS, and AKIN stage were found to be significant predictors of mortality. Hypernatremia (HR 2.00, 95% CI 1.212-3.31; p = 0.0066), but not hyponatremia (HR 1.72, 95% CI 0.89-3.34; p = 0.1068) was associated with mortality. Conclusions: In the burn population, hypernatremia, but not hyponatremia, is an independent predictor of mortality.

ID LIFE-HISTORY STAGE; TERRAPINS MALACLEMYS-TERRAPIN; PREDATION; EMERGENCE;
MOVEMENTS; SURVIVAL; SIZE; NEST
AB Understanding space-use patterns of freshwater turtle hatchlings is critical to guide conservation efforts, yet little is known because of the difficulties in studying this early life-history stage. We investigated post-emergence movements and habitat associations of western pond turtles (Actinemys marmorata) at two study sites in western Oregon using microtransmitters and harmonic radar methods. Hatchlings delayed emergence until spring, with few exceptions. Hatchlings typically remained within 2 m of nests for as long as 59 d after initial emergence. During migration from their nests to aquatic habitat, hatchlings embedded themselves in soil for up to 22 d at stop-over sites. Movements between successive stop-over sites averaged 27 m. Although the number of days turtles remained within 2 m of their nest following emergence varied widely among and within nests, hatchlings entered aquatic habitat relatively synchronously. Hatchlings entered aquatic habitat on average 49 d after initial emergence, and traveled an average of 89 m from their nest site. Hatchlings detected in water were always within 1 m of shore and in areas with dense submerged vegetation and woody debris. Because of delayed emergence and extended post-emergent use of the area adjacent to nests, managers must consider the trade-offs of managing vegetation for nest habitat and the potential harm to hatchlings by vegetation management near nests.

AB Thiourea catalysts accelerate aminolysis of N-acyl homoserine lactones (AHLs), molecules integral to bacterial quorum sensing. The catalysts afford rate enhancement of up to 10 times the control in CD3CN. Mild catalysis in other polar aprotic solvents is still observed, while the activity is attenuated in polar protic solvents.

AB Large river ecology has evolved through time, from perceiving rivers as big streams to accepting rivers as spatiotemporally diverse and complex ecosystems spanning terrestrial, aquatic, and socio-political realms. This review summarizes past and present concepts in large river ecology and highlights uncertainties facing the science and management of large rivers, and provides examples of tools (river restoration and adaptive management) that may be used to continue the advancement of large river ecology into the future. We need to ask, "Where do we go from here?" and, "How do we get there?" The science, management, and policy of large rivers are inseparable and decisions formulated by river stakeholders today will inevitably shape how rivers are studied and managed into the future.

AB This study was undertaken to ascertain the extent of polymorphism in the C-terminal region of Plasmodium falciparum merozoite surface protein (MSP-1) from 119 malaria patients in Tak Province on the western border of Thailand, who were admitted to the Bangkok Hospital for Tropical Diseases, Faculty of Tropical Medicine, Mahidol University, Bangkok, Thailand. P. falciparum infection was confirmed by microscopic examination of peripheral blood smears. Clinical manifestations were categorized into 2 groups: uncomplicated (94 cases) and complicated/severe (25 cases). A 1,040 basepair fragment of P. falciparum MSP-1 gene was compared with MSP-1 of reference strains retrieved from GenBank. The consensus sequences of MSP-1 block 16 showed it belonged to MAD20 genotype, which is the major allele of falciparum malaria from the western border of Thailand. MSP-1 block 16 amino acid fragment could be separated into 2 groups: similar and dissimilar to reference sequence. Four variations in MSP-1 block 16 were similar to 1494K, D1510G, D1556N, and K1696I. MSP-1 block 16 diversity is not significantly associated with clinical manifestation although MAD 20 genotype is the predominant genotype in this area. The genetic data of MSP1 gene of faciparum, malaria isolated from western Thai border contribute, to the existing genetic database of Thai P. falciparum strain.

AB We derived the jump conditions for Faraday's induction law at the interface of two contacting bodies in both Eulerian and Lagrangian descriptions. An algorithm to implement the jump conditions in the potential formulation of Maxwell equation is presented. Calculations show that the use of the correct jump conditions leads to good agreement with experimental data, whereas the use of incorrect jump conditions can lead to severe inaccuracies in the computational results. Our derivation resolves the jump condition discrepancy found in the literature and is validated with experimental results. Copyright 2013 Author(s).

AB The Chesapeake Bay, USA, suffers from multiple water quality impairments including poor water clarity. A management strategy aimed at improving water clarity through reduction of nutrient and solids loads to the bay is under development. The strategy is informed through the use of the Chesapeake Bay Environmental Modeling Package. We describe herein aspects of the model devoted to suspended solids, a major contributor to poor water clarity. Our approach incorporates a dynamic model of inorganic solids into an eutrophication model, in order to account for interactions between physical and biotic factors which influence suspended solids transport and fate. Solids budgets based on the model indicate that internal production of organic solids is the largest source of suspended solids to the mainstem bay. Scenario analysis indicates that control of solids loads reduces solids concentration in the vicinity of the loading sources. Control of nutrient loads provides more widespread but lesser reductions in suspended solids. Published by Elsevier Ltd.

AB Effects of trailing-edge flap gaps on rotor performance are investigated using a high-fidelity coupled computational fluid dynamics computational structural dynamics analysis. Both integral flap (the flap is an integral part of the blade such that there are no physical gaps at the flap ends) and discrete flap (the flap is a separate entity with physical gaps in the span and chord directions) are examined on an UH-60A rotor at high-speed forward-flight conditions. A novel grid deformation scheme based on the Delaunay graph mapping is developed and implemented to allow the computational fluid dynamics modeling of the gaps with minimal distortion of mesh around the flap gap regions. This method offers an alternative to the traditional approach of modeling such configurations using overset meshes. The simulation results show that the effectiveness of the flap is minimally affected with span gaps; the penalty on rotor performance is of the order of 1% compared to the integral flap. On the other hand, the chord gaps significantly degrade the benefits of active flap on rotor performance due to the flow penetration between the upper and lower surfaces of the flap.

TI Experimental Investigation of Parachute Canopies with Rectangular
Parallelepiped Geometries
SO JOURNAL OF AIRCRAFT
LA English
DT Article
AB A series of wind-tunnel experiments were conducted in which the drag characteristics and inflated geometry of model parachute canopies with rectangular parallelepiped geometries (polyhedron) were examined. The model-canopy layouts were the same as cross canopies with the adjacent sides completely attached together. All models had a base dimension of 0.2 m, and aspect ratios ranged from 0.2 to 1.2. The models did not have a central vent or any other geometric porosity. The data show the inflated geometry of the canopy differs from the constructed geometry with the smallest change occurring at a constructed aspect of 0.8 and the variation becomes larger for increasing or decreasing constructed aspect ratios. The data also indicate the aerodynamic drag coefficient, based on the projected area, has a maximum value of approximately one for the constructed aspect ratio of 0.3 corresponding to an inflated aspect ratio of 0.53. The drag coefficient is less for smaller and larger aspect-ratio models. If scaled by the canopy surface area drag of the rectangular parallelepiped canopies is lower than flat circular canopy designs. These findings are consistent with the past findings on other flexible parachute canopies and rigid bluff bodies.

AB In the three decades since the eradication of smallpox and cessation of routine vaccination, the collective memory of the devastating epidemics caused by this orthopoxvirus has waned, and the human population has become increasingly susceptible to a disease that remains high on the list of possible bioterrorism agents. Research using surrogate orthopoxviruses in their natural hosts, as well as limited variola virus research in animal models, continues worldwide; however, interpretation of findings is often limited by our relative lack of knowledge about the naturally occurring disease. For modern comparative pathologists, many of whom have no first-hand knowledge of naturally occurring smallpox, this work provides a contemporary review of this historical disease, as well as discussion of how it compares with human monkeypox and the corresponding diseases in macaques.

AB Flight tests with a German Army Sikorsky CH-53G helicopter were performed to evaluate the applicability and repeatability of the U.S. Army's Aeronautical Design Standard (ADS)-33E-PRE cargo helicopter handling qualities requirements. The objectives were to corroborate earlier findings and to propose modifications if deemed necessary. The CH-53G was chosen because it is the largest helicopter operated by the German Army, and its dedicated role is cargo and troop transport. The quantitative criteria and the associated boundaries as specified in the standard were largely confirmed. Several flight test maneuvers were revised and tailored. Generally, the heights for performing the near-earth maneuvers were increased. The time/tolerances experienced were borderline desired/adequate or adequate.

AB Flight control design and analysis requires an accurate flight dynamics model of the bare airframe and its associated uncertainties, as well as the integrated system model (block diagrams), across the frequency range of interest. Frequency response system identification methods have proven to efficiently fulfill these modeling requirements in recent rotorcraft flight control applications. This paper presents integrated system identification methods for control law design with flight-test examples of the Fire Scout MQ-8B, S-76, and ARH-70A. The paper also looks toward how system identification could be used in new modeling challenges such as large tilt-rotors and uniquely configured unmanned aircraft.

AB Objective: To explore the cross-sectional relationships between blood eicosapentaenoic acid + docosahexaenoic acid (HSOmega-3 Index (R)) and sleep disorders, depression, anxiety, and neurocognitive performance in Servicemembers deployed to Iraq.
Methods: Servicemembers with mild-to-moderate depression by the Patient Health Questionnarie-9 from two US military camps were invited to participate in this study. A battery of validated psychosocial (Pittsburgh Sleep Quality Index, and Zung Depression, Zung Anxiety, Epworth Sleepiness, and Combat Experiences scales) and computerized neurocognitive tests were completed by each participant. Five neurocognitive domain scores were calculated - Processing Speed, Complex Attention, Reaction Time, Cognitive Flexibility (CF), and Executive Function (EF). A drop of blood was also collected on an anti-oxidant-treated filter paper card and sent for HS-Omega-3 Index (R) analysis. An analysis of variance contrast was used to test for linear trends between quartiles of the HS-Omega-3 Index (R) for both EF and CF.
Results: The mean HS-Omega-3 Index (R) was 3.5 +/- 0.7% (n = 78). The HS-Omega-3 Index (R) was not significantly associated with scores for anxiety, depression, or sleep, whether assessed as continuous or dichotomous variables, but was directly associated with CF and EF (P < 0.02 and 0.01, respectively), especially in the 81% who reported poor sleep quality. In those with poor sleep quality (n = 63), EF and CF were higher (P = 0.005) in subjects with Omega-3 levels above versus below the mean.
Conclusion: Optimal neurocognitive performance is essential during deployment. Our finding that EF and CF were positively related to HS-Omega-3 Index (R) suggests that improving omega-3 status through an increase in omega-3 intake may improve neurocognitive performance and confer an element of resilience to poor sleep.

AB Mechanistic modeling of water resources systems is a broad field with abundant challenges. We consider classes of model formulations that are considered routine, the focus of current work, and the foundation of foreseeable work over the coming decade. These model formulations are used to assess the current and evolving state of solution algorithms, discretization methods, nonlinear and linear algebraic solution methods, computational environments, and hardware trends and implications. The goal of this work is to provide guidance to enable modelers of water resources systems to make sensible choices when developing solution methods based upon the current state of knowledge and to focus future collaborative work among water resources scientists, applied mathematicians, and computational scientists on productive areas.

AB A direct, sensitive, and rapid method for the detection of smokeless powder components, from five different types of ammunition, is demonstrated using laser electrospray mass spectrometry (LEMS). Common components found in powder, such as ethyl centralite, methyl centralite, dibutyl phthalate, and dimethyl phthalate, are detected under atmospheric conditions without additional sample preparation. LEMS analysis of the powders revealed several new mass spectral features that have not been identified previously. Offline principal component analysis and discrimination of the LEMS mass spectral measurements resulted in perfect classification of the smokeless powder with respect to manufacturer.

AB The US Army owns and maintains approximately 2000 bridges on its installations spread out in the United States and around the world. From this inventory, 67% are concrete bridges, most of which do not have design or as-built plans to effectively evaluate their condition/capacity. In addition, military vehicles have unique characteristics that are difficult to take into account when analytical analyses are performed. For these purposes, the US Army Engineer Research and Development Center has been adapting non-destructive techniques. The most promising concept explored thus far involves bridge rating through non-destructive load testing in combination with Ground Penetrating Radar (GPR) techniques. Field load testing techniques are valuable for evaluating the capacity of existing bridges and accurately characterize the structure's live-load response while GPR techniques provide valuable information regarding the internal reinforcement as well as the condition of the concrete. This article will provide a brief description as well as the results from recent evaluations performed on reinforced concrete bridges at military installations. (C) 2010 Published by Elsevier Ltd.

AB A model-based correlation detection scheme is presented with the aim of detecting and localizing subsurface tunnel infrastructure in an automated fashion. Our goal is to develop a comprehensive detection technology that can be fielded and successfully used by nonexperts, while simultaneously being sufficiently robust as to be effective. Our correlation detection algorithm relies on a library of model signals that are generated using an analytical model of a thin subsurface wire in a homogeneous half-space. The wire is illuminated using an active transmitter source (12, 20, or 200 kHz), and its response is sensed using a man-portable electromagnetic gradiometer (EMG) system. The performance of the detector is assessed using synthetic data and receiver operating characteristic (ROC) analysis as well as experimental data collected during a field test. Preliminary ROC results indicate that at sufficient signal-to-noise ratio, the detector can achieve detection probabilities greater than 0.9 with corresponding false alarm rates of less than one every 1000 m. Results from the field tests revealed that the responses from the EMG can be used to detect and localize (to within 0.5 m in the horizontal) a wire target down to a depth of at least 7 m. We believe the EMG system and correlation detector combine to form a promising technology for detecting tunnel infrastructure that can be used by experts and, more importantly, nonexperts as well.

AB In this paper, a novel nonlinear technique for hyperspectral image (HSI) classification is proposed. Our approach relies on sparsely representing a test sample in terms of all of the training samples in a feature space induced by a kernel function. For each test pixel in the feature space, a sparse representation vector is obtained by decomposing the test pixel over a training dictionary, also in the same feature space, by using a kernel-based greedy pursuit algorithm. The recovered sparse representation vector is then used directly to determine the class label of the test pixel. Projecting the samples into a high-dimensional feature space and kernelizing the sparse representation improve the data separability between different classes, providing a higher classification accuracy compared to the more conventional linear sparsity-based classification algorithms. Moreover, the spatial coherency across neighboring pixels is also incorporated through a kernelized joint sparsity model, where all of the pixels within a small neighborhood are jointly represented in the feature space by selecting a few common training samples. Kernel greedy optimization algorithms are suggested in this paper to solve the kernel versions of the single-pixel and multi-pixel joint sparsity-based recovery problems. Experimental results on several HSIs show that the proposed technique outperforms the linear sparsity-based classification technique, as well as the classical support vector machines and sparse kernel logistic regression classifiers.

AB We consider the quadratic family of complex maps given by , where c is the centre of a hyperbolic component in the Mandelbrot set. Then, we introduce a singular perturbation on the corresponding bounded super-attracting cycle by adding one pole to each point in the cycle. When c = - 1, the Julia set of q - 1 is the well-known basilica and the perturbed map is given by , where are integers, and ? is a complex parameter such that |?| is very small. We focus on the topological characteristics of the Julia and Fatou sets of f ? that arise when the parameter ? becomes non-zero. We give sufficient conditions on the order of the poles so that for small ?, the Julia sets consist of the union of homeomorphic copies of the unperturbed Julia set, countably many Cantor sets of concentric closed curves, and Cantor sets of point components that accumulate on them.

AB We exploit plausibly exogenous variation in overseas deployment assignment to estimate the effect of combat exposure on psychological well-being. Controlling for pre-deployment mental health, we find that active-duty soldiers deployed to combat zones are more likely to suffer from post-traumatic stress disorder (PTSD) than their counterparts deployed outside the United States in non-combat zones. Among those deployed to combat zones, those deployed to locales where they engage in enemy firefight or witness allied or civilian deaths are at an increased risk for suicidal ideation and PTSD relative to their active-duty counterparts deployed to combat zones without enemy firefight.

TI "The Best Little Army"
SO JOURNAL OF MILITARY HISTORY
LA English
DT Article
AB Historians have generally assumed that the poor showing made by the South Korean military in the opening stages of the Korean War was inevitable and have attributed much of the blame for this to the U.S. Army advisory group in Korea, known colloquially as "KMAG." However, a closer look at the documentary evidence shows that KMAG was keenly aware of the South Korean military's shortcomings and was doing its best to correct them as war came. Although KMAG's program to improve the equipment and leadership of the South Korean military and to focus its efforts on conventional defense, as opposed to counterinsurgency activities, proved insufficient to stop the North Korean invasion, U.S. advisors did succeed in forging an infrastructure that allowed the South Korean army to survive and eventually to grow into a potent military force during the war.

TI Eating Soup with a Spoon: The U.S. Army as a "Learning Organization" in
the Vietnam War
SO JOURNAL OF MILITARY HISTORY
LA English
DT Article
AB Standard Vietnam War narratives often argue that the U.S. Army lost the war because it failed to learn and adapt to the conditions of an unconventional conflict. Based on a reappraisal of learning processes rather than on the outcome of the war, this essay argues that as an organization, the U.S. Army did learn and adapt in Vietnam; however, that learning was not sufficient, in itself, to preserve a South Vietnam in the throes of a powerful nationalist upheaval. A reexamination of the Army's strategic approach, operational experiences, and organizational changes reveals that significant learning did occur during the Vietnam War despite the conflict's final result.

AB Context: G-protein coupled receptor (GPCR) signaling in skeletal muscle is incompletely understood; in particular, the signaling pathways that regulate GPCR-mediated signaling in skeletal muscle are only beginning to be established. Lysophosphatidic acid (LPA) is a GPCR agonist that has previously been shown to activate protein kinase D (PKD) in non-muscle cells; however, whether PKD is activated in response to LPA in skeletal muscle myoblasts, and the identities of signaling intermediates that regulate this activation, have not been defined. Objective: To determine whether PKD is activated in response to LPA administration in myoblasts, and to define the signaling pathways that mediate LPA-stimulated PKD phosphorylation. Methods: C2C12 myoblasts were treated with LPA and signaling pathways examined by means of Western immunoblotting and real-time PCR (RT-PCR). Pharmacological inhibition and RNA-interference were used to target specific molecules to determine their involvement in LPA-induced PKD phosphorylation. Results: Treatment of myoblasts with exogenous LPA revealed that PI3K p110 beta mediated PKD phosphorylation at Ser 748 and at Ser 916 through kinase-dependent and kinase-independent mechanisms. Loss of PKC delta, but not the loss of PKC alpha, prevented LPA-induced PKD phosphorylation. The PKD isoform responsive to LPA treatment was identified as PKD2. Conclusion: These results indicate that LPA-stimulated PKD2 phosphorylation requires PKC delta and non-catalytic actions of PI3K p110 beta, and provide new information with respect to GPCR-mediated signal transduction in myoblasts.

AB Objective To describe the patient population, injuries, and treatment received on the battlefield, and ultimate outcome of U.S. military working dogs that incurred gunshot wound (GSW) injury in Operation Enduring Freedom (Afghanistan) or Operation Iraqi Freedom (Iraq). Design Retrospective study between January 2003 and December 2009. Animals Twenty-nine military working dogs from the U.S. military with confirmed GSW injuries incurred in combat in Operation Enduring Freedom or Operation Iraqi Freedom. Interventions None. Measurements and Main Results Clinical data from battlefield treatment, which includes care from the point of injury through arrival to, but not including, a designated veterinary treatment facility. Twenty-nine dogs were injured between 2003 and 2009. All but one of the injuries were from high caliber, high velocity weapons. Of the 29 injured dogs, 11 survived the injuries and 18 died (38% survival rate). Of the dogs that died, all but 1 died from catastrophic nonsurvivable injuries before treatment or evacuation could be instituted. The thorax was the most common site of injury (50%) followed by extremity wounds (46%). The leading cause of death from GSWs was from thoracic wounds, followed by head wounds. Dogs with extremity wounds as their only injury were most likely to survive, and dogs with multiple injuries were least likely to survive. All surviving dogs received treatment at the point of injury by military medics and dog handlers consistent with Tactical Combat Casualty Care guidelines for combat injuries in human service members. Of the 11 that survived, all dogs returned to full duty with subsequent deployment to combat zones. Location of wounds and injury severity at the time of presentation to veterinary care was not correlated with length of time until return to duty.

AB Hemorrhage is responsible for a large percentage of trauma-related deaths but the mechanisms underlying tissue ischemia are complex and not well understood. Despite the evidence linking glycocalyx degradation and hemorrhagic shock, there is no direct data obtained in vivo showing glycocalyx thickness reduction in skeletal muscle venules after hemorrhage. We hypothesize that damage to the endothelial glycocalyx is a key element in hemorrhage pathophysiology and tested the hypothesis that hemorrhage causes glycocalyx degradation in cremaster muscle microvessels. We utilized intravital microscopy to estimate glycocalyx thickness in 48 microvessels while other microvascular parameters were measured using non-invasive techniques. Systemic physiological parameters and blood chemistry were simultaneously collected. We studied 27 post-capillary venules (<16 mu m diameter) of 8 anesthetized rats subjected to hemorrhage (40% of total blood volume). Six control rats were equally instrumented but not bled. Dextrans of different molecular weights labeled with FITC or Texas Red were injected. Glycocalyx thickness was estimated from the widths of the fluorescence columns and from anatomical diameter. While control rats did not show remarkable responses, a statistically significant decrease of about 59% in glycocalyx thickness was measured in venules after hemorrhagic shock. Venular glycocalyx thickness and local blood flow changes were correlated: venules with the greatest flow reductions showed the largest decreases in glycocalyx. These changes may have a significant impact in shock pathophysiology. Intravital microscopy and integrated systems such as the one described here may be important tools to identify mechanisms by which resuscitation fluids may improve tissue recovery and outcome following hemorrhage.

AB Escherichia coli were genetically modified to enable programmed motility, sensing, and actuation based on the density of features on nearby surfaces. Then, based on calculated feature density, these cells expressed marker proteins to indicate phenotypic response. Specifically, site-specific synthesis of bacterial quorum sensing autoinducer-2 (AI-2) is used to initiate and recruit motile cells. In our model system, we rewired E. coli's AI-2 signaling pathway to direct bacteria to a squamous cancer cell line of head and neck (SCCHN), where they initiate synthesis of a reporter (drug surrogate) based on a threshold density of epidermal growth factor receptor (EGFR). This represents a newtype of controller for targeted drug delivery as actuation (synthesis and delivery) depends on a receptor density marking the diseased cell. The ability to survey local surfaces and initiate gene expression based on feature density represents a new area-based switch in synthetic biology that will find use beyond the proposed cancer model here.

TI Frequent In-Migration and Highly Focal Transmission of Dengue Viruses

AB Revealing the patterns and determinants of the spread of dengue virus (DENV) at local scales is central to understanding the epidemiology and evolution of this major human pathogen. We performed a phylogenetic analysis of the envelope (E) genes of DENV-1, -2, -3, and -4 isolates (involving 97, 23, 5, and 74 newly collected sequences, respectively) sampled from school-based cohort and village-based cluster studies in Kamphaeng Phet, Thailand, between 2004 and 2007. With these data, we sought to describe the spatial and temporal patterns of DENV spread within a rural population where a future vaccine efficacy trial is planned. Our analysis revealed considerable genetic diversity within the study population, with multiple lineages within each serotype circulating for various lengths of time during the study period. These results suggest that DENV is frequently introduced into both semi-urban and rural areas in Kamphaeng Phet from other populations. In contrast, the persistence of viral lineages across sampling years was observed less frequently. Analysis of phylogenetic clustering indicated that DENV transmission was highly spatially and temporally focal, and that it occurred in homes rather than at school. Overall, the strength of temporal clustering suggests that seasonal bottlenecks in local DENV populations facilitate the invasion and establishment of viruses from outside of the study area, in turn reducing the extent of lineage persistence.

AB Many decadal climate prediction efforts have been initiated under phase 5 of the World Climate Research Programme Coupled Model Intercomparison Project. There is considerable ongoing discussion about model deficiencies, initialization techniques, and data requirements, but not much attention is being given to decadal climate information (DCI) needs of stakeholders for decision support. Here, the authors report the results of exploratory activities undertaken to assess DCI needs in water resources and agriculture sectors, using the Missouri River basin as a case study. This assessment was achieved through discussions with 120 stakeholders.
Stakeholders' awareness of decadal dry and wet spells and their societal impacts in the basin are described, and stakeholders' DCI needs and potential barriers to their use of DCI are enumerated. The authors find that impacts, including economic impacts, of decadal climate variability (DCV) on water and agricultural production in the basin are distinctly identifiable and characterizable. Stakeholders have clear notions about their needs for DCI and have offered specific suggestions as to how these might be met. However, while stakeholders are eager to have climate information, including decadal climate outlooks (DCOs), there are many barriers to the use of such information. The first and foremost barrier is that the credibility of DCOs is yet to be established. Second, the nature of institutional rules and regulations, laws, and legal precedents that pose obstacles to the use of DCOs must be better understood and means to modify these, where possible, must be sought. For the benefit of climate scientists, these and other stakeholder needs are also articulated in this paper.

AB The development of barium-free pyrotechnic illuminants is described. Heavy metal barium nitrate oxidizer and strontium nitrate oxidizer were replaced with sodium nitrate to adequately address environmental concerns while providing the brightest possible illuminant. The new formulations further address environmental concerns and mitigate single-point-of-failure through the replacement of polyester-based Laminac 4116/Lupersol binder system with the epoxy-based Epon 813/Versamid 140 binder system. The new formulations were found to burn longer and brighter than the control with a low sensitivity to various ignition stimuli.

AB The prevalence of hearing loss varies with age, affecting at least 25 percent of patients older than 50 years and more than 50 percent of those older than 80 years. Adolescents and young adults represent groups in which the prevalence of hearing loss is increasing and may therefore benefit from screening. If offered, screening can be performed periodically by asking the patient or family if there are perceived hearing problems, or by using clinical office tests such as whispered voice, finger rub, or audiometry. Audiometry in the family medicine clinic setting is a relatively simple procedure that can be interpreted by a trained health care professional. Pure-tone testing presents tones across the speech spectrum (500 to 4,000 Hz) to determine if the patient's hearing levels fall within normal limits. A quiet testing environment, calibrated audiometric equipment, and appropriately trained personnel are required for in-office testing. Pure-tone audiometry may help physicians appropriately refer patients to an audiologist or otolaryngologist. Unilateral or asymmetrical hearing loss can be symptomatic of a central nervous system lesion and requires additional evaluation. (Am Fam Physician. 2013;87(1) :41-47.

AB Two formulations of a new live tetravalent dengue virus (DENV) vaccine produced using re-derived master seeds from a precursor vaccine and that same precursor vaccine as a control were compared in a placebo-controlled, randomized, observer-blind, phase II trial of 86 healthy adults. Two vaccine doses were administered 6 months apart; a third dose was offered to a subset. Symptoms and signs of dengue-like illness reported after vaccination were mild to moderate, transient, and occurred with similar frequency among recipients of the new DENV vaccine and placebo, except for rash. Neither dengue nor vaccine-related serious adverse events were reported. The first DENV vaccine dose was moderately immunogenic; the second dose increased the potency and breadth of the neutralizing antibody response. Tetravalent response rates to the new formulations were 60% and 66.7% in unprimed subjects. A third dose did not increase tetravalent antibody rates. The new DENV vaccine candidates merit additional evaluation.

ID NEAREST-NEIGHBORS; MAMMOTH MOUNTAIN; SLAB AVALANCHES; STABILITY;

AB At ski areas, a majority of avalanches fail in storm snow. Using thousands of observations from avalanche control work at Mammoth Mountain, CA, USA, a large coastal ski area, I analyzed important predictors of avalanche activity. New (24 h) precipitation increased avalanche activity, while changing temperatures and different wind patterns had no effect. If slopes remained undisturbed for one day after snowfall, the number and size of avalanches as well as the explosive yield (avalanches per shot) were all significantly reduced. I also examined a smaller dataset of Extended Column Test (ECT) results and their relation to avalanche activity. ECT propagation was a powerful predictor; days with ECTs that propagated had significantly more avalanches and larger sizes. Days with propagating ECTs also had significantly greater new snow amounts, with a threshold value of 0.29 m of new snow, very close to the 031 m threshold from Atwater's 10 factors. That new precipitation above a threshold causes greater avalanche activity is not a new finding; the new finding is that ECT propagation (versus non-propagation) also has a similar new snow threshold. Thus, I suggest that ECT propagation is an important tool to predict explosively-triggered avalanches in storm snow. (C) 2012 Elsevier B.V. All rights reserved.

TI Pili Annulati Associated With Hair Fragility: Cause or Coincidence?
SO CUTIS
LA English
DT Article
ID MICROSCOPY; FOLLICLES
AB Pili annulati is a disorder that produces a spangled appearance to the hair, caused by alternating light and dark banding of hair shafts. This phenomenon is created by abnormal cavities in the cortex of the hair shaft, which produces lighter bands seen on clinical examination. Complications of pili annulati are limited; the most noicoworthy complication is increased breakage secondary to weathering of the abnormal hair shafts. We report a case of a 14-year-old adolescent girl with pili annulati and progressive hair loss of 2 months' duration. Most of her hairs were notably short, spangled, and lusterless with light and dark banding observed with handheld magnification. light microscopy demonstrated alternating light and dark bands, and the dark bands had the typical appearance of air-filled spaces. Gentler hair grooming practices were recommended, and at a follow-up visit, the appearance of the hair had improved with darker and longer shafts. This case should alert clinicians to look for,pili annulati when hair fragility is present. Cutis. 2013;91:36-38.

Upon functional analysis, immune response was the most enriched biological process, and most of the transcripts associated with the immune response were downregulated. Microbial pattern recognition, chemotaxis, antigen presentation and T-cell activation were among the most downregulated immune processes. Transcription factors predicted to be stress-inhibited (IRF7, RELA, NF kappa B1, CREB1, IRF1 and HMGB) regulated genes involved in inflammation, maturation of dendritic cells and glucocorticoid receptor signaling. Many altered transcripts were predicted to be targets of stress-regulated microRNAs. Post-RASP leukocytes exposed ex vivo to Staphylococcal enterotoxin B showed a markedly impaired immune response to this superantigen compared with pre-RASP leukocytes, consistent with the suppression of the immune response revealed by transcriptome analyses. Our results suggest that suppression of antigen presentation and lymphocyte activation pathways, in the setting of normal blood cell counts, most likely contribute to the poor vaccine response, impaired wound healing and infection susceptibility associated with chronic intense stress.

ID PHASE
AB This research considers the linear-FM (LFM) of a noise radar waveform for resolving targets when channel noise and four popular radar sidelobe weighting functions are considered. By using large time-bandwidth products and systematically varying the phase scaling factor kappa, results from the digital matched filter output provide evidence that the LFM noise waveform 1) has range-Doppler resolution similar to conventional chirp waveforms and 2) has a low probability of intercept (LPI) similar to random noise waveforms. We acquire the results using a computer-based simulation and verify the location of target peaks using the chirp waveform output for both stationary and moving target cases.

AB Staphylococcus pseudintermedius is an opportunistic pathogen in dogs. Four housekeeping genes with allelic polymorphisms were identified and used to develop an expanded multilocus sequence typing (MLST) scheme. The new seven-locus technique shows S. pseudintermedius to have greater genetic diversity than previous methods and discriminates more isolates based upon host origin.

AB Li, H.; Lin, L., and Burks-Copes, K.A., 2013. Modeling of coastal inundation, storm surge, and relative sea-level rise at Naval Station Norfolk, Norfolk, Virginia, U.S.A. Journal of Coastal Research, 29(1), 18-30. Coconut Creek (Florida), ISSN 0749-0208. The potential risk and effects of storm-surge damage caused by the combination of hurricane-force waves, tides, and relative sea-level-rise (RSLR) scenarios were examined at the U.S. Naval Station, Norfolk, Virginia. A hydrodynamic and sediment transport modeling system validated with measured water levels from Hurricane Isabel was used to simulate two synthesized storms representing 50-year and 100-year return-period hurricanes, a northeaster, and five future RSLR scenarios to evaluate the combined impacts of inundation on this military installation in the lower Chesapeake Bay. The naval base topography and nearshore water body of Hampton Roads were included in the coastal modeling system (CMS), a suite of surge, circulation, wave, sediment transport, and morphology evolution models. The modeling domain was a rectangular area covering the entire Naval Station Norfolk in the Hampton Roads and the mouths of the James and Elizabeth rivers. A variable-resolution grid system was created with a finer resolution of 10 m in the naval base and a coarser resolution of 300 m in the regions away from the base. The boundary-forcing conditions to the CMS were regional storm surge produced by the ADvanced CIRCulation (ADCIRC),and wave conditions by the Simulating WAve Nearshore (SWAN) model. The CMS calculated the local water-surface elevation and storm-surge inundation for combined RSLR, surge, waves, and wind. Results indicate that synthetic storms would cause extensive inundation of coastal land around the naval base. Approximately 60% of the land would be under water with the 100-year storm for the present sea level, and 80% for estimated RSLR of 2 m.

AB Dimethyl Sulfoxide (DMSO) was evaluated as a practical solvent for the rechargeable lithium air battery. Redox characteristics of the dissolved oxygen and its reduction products in the presence of lithium hexafluorophosphate (LiPF6) supporting electrolyte were studied via cyclic, rotating disk (RDE) and ring-disk (RRDE) electrode voltammetry. The DMSO medium facilitates reversible reduction and oxidation processes in contrast to other solvent-based electrolytes studied. Galvanostatic discharge-charge cycling of the Li-O-2 cells has shown characteristics of rechargeability expected from voltammetric studies. Multiple high-efficiency discharge-charge cycles are possible if the depth of discharge of the carbon cathode is limited to avoid excessive passivation by the discharge products. The discharge voltage of this Li-O-2 cell is higher than cells assembled with other non-aqueous organic electrolytes, an attribute ascribed to the stability of superoxide (O-2(-)), the one-electron reduction product of oxygen.

AB p-side-down, single heterostructure n-InGaN/p-GaN light emitting diodes grown by molecular beam epitaxy exhibited stable peak emission wavelengths as long as 550nm for current densities in excess of 100 A/cm(2), and minimal efficiency droop up to 150 A/cm(2) without the use of an electron blocking layer. This behavior is consistent with the formation of a two-dimensional hole gas in the n-InGaN layer and a higher barrier to electron overflow in the conduction band due to the negative polarization charge at the n-InGaN/p-GaN interface.

AB Pentas micrantha is used in the East African indigenous medicine to treat malaria. In the first investigation of this plant, the crude methanol root extract showed moderate antiplasmodial activity against the W2- (3.37 mu g/mL) and D6-strains (4.00 mu g/mL) of Plasmodium falciparum and low cytotoxicity (>450 mu g/mL, MCF-7 cell line). Chromatographic separation of the extract yielded nine anthraquinones, of which 5,6-dihydroxylucidin-11-O-methyl ether is new. Isolation of a munjistin derivative from the genus Pentas is reported here for the first time. The isolated constituents were identified by NMR and mass spectrometric techniques and showed low antiplasmodial activities.

AB Supercapacitors with both high energy and high power densities are critical for many practical applications. In this paper, we discuss the design and demonstrate the fabrication of flexible asymmetric supercapacitors based on nanocomposite electrodes of MnO2, activated carbon, carbon nanotubes and graphene. The combined unique properties of each of these components enable highly flexible and mechanically strong films that can serve as electrodes directly without using any current collectors or binders. Using these flexible electrodes and a roll-up approach, asymmetric supercapacitors with 2 V working voltage were successfully fabricated. The fabricated device showed excellent rate capability, with 78% of the original capacitance retained when the scan rate was increased from 2 mV s(-1) to 500 mV s(-1). Owing to the unique composite structure, these supercapacitors were able to deliver high energy density (24 W h kg(-1)) under high power density (7.8 kW kg(-1)) conditions. These features could enable supercapacitor based energy storage systems to be very attractive for a variety of critical applications, such as the power sources in hybrid electric vehicles and the back-up powers for wind and solar energy, where both high energy density and high power density are required.

AB Objective: To describe the prevalence of neurocognitive impairment (NCI) among early diagnosed and managed HIV-infected persons (HIV+) compared to HIV-negative controls.
Methods: We performed a cross-sectional study among 200 HIV+ and 50 matched HIV-uninfected (HIV-) military beneficiaries. HIV+ patients were categorized as earlier (<6 years of HIV, no AIDS-defining conditions, and CD4 nadir >200 cells/mm(3)) or later stage patients (n = 100 in each group); both groups were diagnosed early and had access to care. NCI was diagnosed using a comprehensive battery of standardized neuropsychological tests.
Results: HIV+ patients had a median age of 36 years, 91% were seroconverters (median window of 1.2 years), had a median duration of HIV of 5 years, had a CD4 nadir of 319, had current CD4 of 546 cells/mm(3), and 64% were on highly active antiretroviral therapy (initiated 1.3 years after diagnosis at a median CD4 of 333 cells/mm(3)). NCI was diagnosed among 38 (19%, 95% confidence interval 14%-25%) HIV+ patients, with a similar prevalence of NCI among earlier and later stage patients (18% vs 20%, p = 0.72). The prevalence of NCI among HIV+ patients was similar to HIV- patients.
Conclusions: HIV+ patients diagnosed and managed early during the course of HIV infection had a low prevalence of NCI, comparable to matched HIV-uninfected persons. Early recognition and management of HIV infection may be important in limiting neurocognitive impairment. Neurology (R) 2013;80:371-379

AB This study examined the nature, concomitants, and consequences of stress-related biological reactivity and regulation among Army nurses. Saliva was collected, heart rate (HR) and blood pressure (BP) recorded from 38 Army nurses (74% female; mean age 28.5 years [SD = 6.5]) before, during, and after participation in the Combat Casualty Stress Scenario (CCSS). Saliva was assayed for cortisol and alpha-amylase (sAA). The CCSS simulates emergency combat rescue, employing two simulated combat casualties, aversive body odors, recorded battlefield sounds, and smoke in a low light environment. Participants locate and conduct preliminary assessments of the simulated patients, triage based on injury severity, initiate treatment, and coordinate medical evacuation by radio. Results revealed large magnitude increases in cortisol, sAA, HR, systolic BP and diastolic BP in response to the CCSS, followed by recovery to baseline levels 30 min after the task for all physiological parameters except cortisol. Age, gender, perceived difficulty of the CCSS, and previous nursing experience were associated with individual differences in the magnitude of the physiological responses. Lower levels of performance related to triage and treatment were associated with higher levels of reactivity and slower recovery for some of the physiological measures. The findings raise important questions regarding the utility of integrating measures of the psychobiology of the stress response into training programs designed to prepare first responders to handle highly complex and chaotic rescue situations.

AB Hydride vapor phase epitaxy (HVPE) grown GaN was evaluated for high power Schottky diodes (SDs) because it contains much less carbon and grows much more rapidly than other typical growth methods. The results are encouraging for applications <1000 V in that breakdown voltages (V-B) near this value can be readily obtained with figures of merit (FOM) of approximate to 250 MW/cm(2) that most likely can be improved upon. The properties of the SDs, however, vary dramatically from point to point, and cannot be attributed solely to processing issues. It is much more likely this variation across the wafer can be attributed to material inhomogeneities such as dislocations and point defects. (C) 2012 Elsevier Ltd. All rights reserved.

AB Background: Effective written communication is a core competency for medical students, but it is unclear whether or how this skill is evaluated in clinical clerkships. Purpose: This study identifies current requirements and practices regarding required written work during internal medicine clerkships. Methods: In 2010, Clerkship Directors of Internal Medicine (CDIM) surveyed its institutional members; one section asked questions about students written work. Results were compared to similar, unpublished CDIM 2001 survey questions. Results: Requirements for student-written work were nearly universal (96% in 2001 and 100% in 2010). Only 23% used structured evaluation forms and 16% reported written work was weighted as a percentage of the final grade, although 72% of respondents reported that written work was factored into global ratings. Conclusions: Despite near universal requirements for student written work, structured evaluation was not commonly performed, raising concern about the validity of factoring these assessments into grades.

AB Structural transparent material systems are critical for many military and civilian applications. Transparent armor systems can consist of a wide variety of glass laminate assemblies with polymeric bonding interfaces and backing as well as the inclusion of polycrystalline ceramic (AlON, spinel) and single crystals (sapphire) as front facing materials. Over the last 20 years as the threats have escalated and become more varied, the challenges for rapidly developing optimized threat specific transparent armor packages have become extremely complex. Ultimate failure of structural ceramics in impact events is a function of the temporal and spatial interaction of the macro-stresses at the macro-, micro- and nano-structural scale, including elastic and inelastic (plastic) deformation, crack nucleation, damage evolution and resulting failure from the macro-scale (top down) and/or from the nano-scale (bottom up). In order to accelerate the development of validated design and predictive performance models, a systematic series of experimental investigations have been carried out on various non-crystalline ceramics (glass), single crystal (sapphire) and polycrystalline ceramics (AlON). The Edge-on Impact (EOI) test coupled with a high-speed Cranz-Schardin film camera has been extensively used on a variety of monolithic and laminated glasses, AlON and crystallographically controlled sapphire single crystals to visualize and quantify stress wave, crack and damage propagation. A modified Kolsky bar technique instrumented with a high speed digital camera has been utilized in an unconfined and confined test sample mode to examine the dynamic deformation and failure of AlON undergoing uniaxial, high strain rate compression. Real time photography has clearly demonstrated the critical influence of defects and post mortem characterization of fragments resulting from these tests have revealed the influence of micro-deformational twining and cleavage down to the nano-scale. Finally, a brief summary of work using ultra-high-speed photography of the impact of conventional projectiles on glass and AlON will be presented. These experimental results will be absolutely critical to help evolve and validate existing models used in computer codes to simulate the impact performance of brittle materials.

AB Borosilicate (BS) and soda-lime silicate (SLS) glasses are being considered for use as the strike-face in transparent armor systems. This effort examined the effect of surface scratches generated with 1, 5, 10, and 30 N scratching loads on the equibiaxial flexure strength of both glasses including versions of each that had been thermally-tempered. At lower scratch loads there is more lateral cracking associated with the scratches in the BS while the scratches in the SLS predominantly exhibit plastic deformation. At the highest scratch load the damage is dominated by chips and lateral cracking within and along the scratch length. The tempered versions of the SLS appear to have less lateral cracking than the tempered version of the BS glass. In all instances the flexure strength decreases significantly when a 1 N scratch is introduced on the tin surface but when the scratch load increases any additional strength loss is minimal.

DE Color filter array (CFA) demosaicing; edge slope measure; false color
measure; no-reference quality assessment
ID COLOR; INTERPOLATION
AB To address the frequent lack of a reference image or ground truth when performance testing Bayer pattern color filter array demosaicing algorithms, we propose two new no-reference quality assessment algorithms. These algorithms provide a relative comparison of two demosaicing algorithms by measuring the presence of two common artifacts, zippering and false coloring, in their output images. The first algorithm, the edge slope measure, tests the overall sharpness of each of the three color channels, thus estimating the relative edge reconstruction accuracy of each demosaicing algorithm. The second algorithm, the false color measure, estimates deviations from the established constant color difference image model and performs on green-red and green-blue color difference planes, therefore estimating the red and blue channel reconstruction of each demosaicing algorithm. We evaluate and rank common demosaicing algorithms using these new algorithms. Furthermore, we present real image examples for subjective evaluation to justify the rankings suggested by the new quality assessment algorithms.

ACTIVITY; INTEGRAL MEMBRANE; DEATH PATHWAY; PHASE-II
AB Despite efforts to understand and treat acute myeloid. leukemia (AML), there remains a need for more comprehensive therapies to prevent AML-associated relapses. To identify new therapeutic strategies for AML, we screened a library of on- and off-patent drugs and identified the antimalarial agent mefloquine as a compound that selectively kills AML cells and AML stem cells in a panel of leukemia cell lines and in mice. Using a yeast genome-wide functional screen for mefloquine sensitizers, we identified genes associated with the yeast vacuole, the homolog of the mammalian lysosome. Consistent with this, we determined that mefloquine disrupts lysosomes, directly permeabilizes the lysosome membrane, and releases cathepsins into the cytosol. Knockdown of the lysosomal membrane proteins LAMP1 and LAMP2 resulted in decreased cell viability, as did treatment of AML cells with known lysosome disrupters. Highlighting a potential therapeutic rationale for this strategy, leukemic cells had significantly larger lysosomes compared with normal cells, and leukemia-initiating cells overexpressed lysosomal biogenesis genes. These results demonstrate that lysosotnal disruption preferentially targets AML cells and AML progenitor cells, providing a rationale for testing lysosomal disruption as a novel therapeutic strategy for AML.

AB A functionalization method for the specific and selective immobilization of the streptavidin (SA) protein on semiconductor nanowires (NWs) was developed. Silicon (Si) and silicon carbide (SiC) NWs were functionalized with 3-aminopropyltriethoxysilane (APTES) and subsequently biotinylated for the conjugation of SA. Existence of a thin native oxide shell on both Si and SiC NWs enabled efficient binding of APTES with the successive attachment of biotin and SA as was confirmed with x-ray photoelectron spectroscopy, high-resolution transmission electron microscopy, and atomic force microscopy. Fluorescence microscopy demonstrated nonspecific, electrostatic binding of the SA and the bovine serum albumin (BSA) proteins to APTES-coated NWs. Inhibition of nonspecific BSA binding and enhancement of selective SA binding were achieved on biotinylated NWs. The biofunctionalized NWs have the potential to be used as biosensing platforms for the specific and selective detection of proteins.

AB An engorged female Amblyomma helvolum Koch tick was removed from an adult Varanus salvator Laurenti lizard during field collection in Thailand. After using polymerase chain reaction to amplify three genes (16S rDNA, gltA, and OmpA), we discovered the presence of a Rickettsia sp. of the Spotted Fever Group. Phylogenetic analysis revealed that this Rickettsia sp. is closely related to Rickettsia raoultii Mediannikov. Therefore, we report herein for the first time the detection of a novel Spotted Fever Group Rickettsia in an Amblyomma helvolum from a Varanus salvator in Thailand.

DE Buildings; Connections; Full-scale tests; Progressive collapse; Seismic
design; Steel structures
AB This paper presents an experimental study of two full-scale steel beam-column assemblies, each comprising three columns and two beams, to (1) define their response characteristics under a column-removal scenario, including the capacity of the beams and their connections to carry loads through catenary action, and (2) provide experimental data for validation of beam-to-column connection models for assessing the robustness of structural systems. The assemblies represent portions of the exterior moment-resisting frames of two 10-story steel-frame buildings. One test specimen had welded unreinforced flange, bolted web connections, and the other had reduced beamesection connections. When subjected to monotonically increasing vertical displacement of the unsupported center column, both specimens exhibited an initial elastic response dominated by flexure. With increased vertical displacement, the connections yielded, and axial tension developed in the beams. The axial tension in the beams increased until the connections failed under combined bending and axial stresses. The test results show that the rotational capacities of both connections under monotonic column displacement are about twice as large as those based on seismic-test data.

DE Health care; quality control; ischemia; trauma system
ID MAJOR LIMB TRAUMA; TOURNIQUET USE
AB BACKGROUND: In 2008, we showed that incomplete or delayed extremity fasciotomies were associated with mortality and muscle necrosis in war casualties with limb injury. Subsequently, we developed an education program focused on surgeon knowledge gaps regarding the diagnosis of compartment syndrome and prophylactic fasciotomy. The program included educational alerts, classroom training, video instruction, and a research publication. We compared casualty data before and after the program implementation to determine whether the education altered outcomes.
METHODS: Similar to the previous study, a case series was made from combat casualty medical records. Casualties were US military servicemen with fasciotomies performed in Iraq, Afghanistan, or Germany between two periods (periods 1 and 2).
RESULTS: In both periods, casualty demographics were similar. Most fasciotomies were performed to the lower leg and forearm. Period 1 had 336 casualties with 643 fasciotomies, whereas Period 2 had 268 casualties with 1,221 fasciotomies (1.9 vs. 4.6 fasciotomies per casualty, respectively; p < 0.0001). The mortality rate decreased in Period 2 (3%, 8 of 268 casualties) from Period 1 (8%, 26 of 336 casualties; p = 0.0125). Muscle excision and major amputation rates were similar in both periods (p > 0.05). Rates of casualties with revision fasciotomy decreased to 8% in Period 2, (22 of 268 casualties) versus 15% in Period 1 (51 of 336 casualties; p = 0.009).
CONCLUSION: Combat casualty care following implementation of a fasciotomy education program was associated with improved survival, higher fasciotomy rates, and fewer revisions. Because delayed fasciotomy rates were unchanged, further effort to educate providers may be indicated. (J Trauma Acute Care Surg. 2013;74: 259-263.

AGENDA
AB Damage control resuscitation (DCR) is emerging as a standard practice in civilian and military trauma care. Primary objectives include resolution of immediate life threats followed by optimization of physiological status in the perioperative period. To accomplish this, DCR employs a unique hypotensivehemostatic resuscitation strategy that avoids traditional crystalloid intravenous fluids in favor of early blood component use in ratios mimicking whole blood. The presence of uncontrolled major hemorrhage (UMH) coupled with a delay in access to hemostatic surgical intervention remains a primary contributor to preventable death in both combat and in many domestic settings, including rural areas and disaster sites. As a result, civilian and military emergency care leaders throughout the world have sought a means to project DCR principles forward of the traditional trauma resuscitation bay, into such remote environments as disaster scenes, rural health facilities, and the contemporary battlefield. After reflecting on experiences from past conflicts, defining current capability gaps, and examining available and potential solutions, a strategy for remote damage control resuscitation (RDCR) has been proposed. In order for RDCR to progress from concept to clinical strategy, it will be necessary to define existing gaps in knowledge and clinical capability; develop a lexicon so that investigators and operators may understand each other; establish coherent research and development agendas; and execute comprehensive investigations designed to predict, diagnose, and mitigate the consequences of hemorrhagic shock and acute traumatic coagulopathy before they become irreversible. This article seeks to introduce the concept of RDCR; to reinforce the importance of identifying and optimally managing UMH and the resulting shock state as part of a comprehensive approach to out-of-hospital stabilization and en route care; and to propose investigational strategies to enable the development and broad implementation of RDCR principles.

resuscitation in the French Armed Forces Health Service
SO TRANSFUSION

ID FREEZE-DRIED PLASMA
AB Freeze-dried plasma was developed by the US Army for the resuscitation of combat casualties during World War II. The French Military Blood Institute began producing French lyophilized plasma (FLYP) in 1949, in accordance with French blood product guidelines. Since 2010, a photochemical pathogen inactivation process has been implemented to reduce the remaining transfusion-related infectious risk. All quality controls for this procedure verify that the hemostatic properties of FLYP are conserved. FLYP is compatible with all blood types, can be stored at room temperature for 2 years, and its reconstitution requires less than 6 minutes. As a result, FLYP allows quick delivery of all the coagulation proteins and the application of a 1:1 ratio of FLYP and red blood cells in the context of a massive transfusion. Hemovigilance data collected in France since 1994 have included FLYP. Results indicate no reporting of infection related to the use of FLYP. Clinical monitoring with a focus on hemostasis was implemented in 2002 and expanded in 2010. The data, obtained from overseas operations, confirmed the indications, the safety and the clinical efficacy of FLYP. Further research is needed to determine specific indications for FLYP in the therapeutic management of civilian patients with severe hemorrhage.

AB Background After major traumatic injury, patients often require multiple transfusions of fresh frozen plasma (FFP) to correct coagulopathy and to reduce bleeding. A spray-dried plasma (SDP) product has several logistical benefits over FFP use in trauma patients with coagulopathy. These benefits include ease of transport, stability at room temperature, and rapid reconstitution for infusion. Our past work suggests that FFP promotes endothelial stability by inhibiting endothelial permeability.
Study Design and Methods The main goal of this project is to determine if solvent-detergent-treated SDP is equivalent to FFP in inhibiting vascular endothelial cell (EC) permeability and inflammation in vitro. Furthermore, this study aimed to determine if solvent-detergent treatment and spray drying of plasma alters the protective effects of FFP on EC function. The five groups tested in our studies are the following: 1) fresh frozen-thawed plasma (FFP); 2) solvent-detergent-treated FFP; 3) solvent-detergent-treated SDP; 4) lactated Ringer's solution; and 5) Hextend.
Results This study demonstrates that in vitro SDP and FFP equivalently inhibit vascular EC permeability, EC adherens junction breakdown, and endothelial white blood cell binding, an effect that is independent of changes in Vascular Cell Adhesion Molecule 1, Intracellular Adhesion Molecule 1, or E-selectin expression on ECs. Solvent-detergent treatment of FFP does not alter the protective effects of FFP on endothelial cell function in vitro.
Conclusion These data suggest the equivalence of FFP and SDP on modulation of endothelial function and inflammation in vitro.

AB With the advent of remote damage control resuscitation and far-forward surgery, a renewed emphasis has been placed on examining a variety of pharmacologic adjuncts to controlling blood loss before definitive operative intervention. In this paper, the authors review the current state of the art for tranexamic acid (TXA) and its potential benefits to those patients who are in need of a massive transfusion. Specifically addressed are its biologic and pharmacologic properties, as well the results of a number of recent studies. The 2010 CRASH-2 trial randomized in excess of 20,000 patients and demonstrated a reduction in all-cause mortality from 16.0 to 14.5% and death due to bleeding from 5.7 to 4.9%. The 2012 Military Application of Tranexamic Acid in Trauma Emergency Resuscitation study provided a retrospective analysis of 896 wounded cared for at a military hospital in Afghanistan. This study demonstrated a 23.9%-17.4% reduction in all-cause mortality. Finally, they discuss the potential complications associated with TXA use as well as areas of future research, which are needed to solidify our knowledge of TXA and its potential beneficial effects on controlling bleeding.

TRANSFUSION; COMBAT; OPERATIONS; BATTLEFIELD; EVOLUTION; INJURIES;

AB Background In Afghanistan, a substantial portion of resuscitative combat surgery is performed by US Army forward surgical teams (FSTs). Red blood cells (RBCs) and fresh frozen plasma (FFP) are available at these facilities, but platelets are not. FST personnel frequently encounter high-acuity patient scenarios without the ability to transfuse platelets. An analysis of the use of fresh whole blood (FWB) at FSTs therefore allows for an evaluation of outcomes associated with this practice.
Study Design and Methods A retrospective analysis was performed in prospectively collected data from all transfused patients at six FSTs from December 2005 to December 2010. Univariate analysis was performed, followed by two separate propensity score analyses. In-hospital mortality was predicted with the use of a conditional logistic regression model that incorporated these propensity scores. Subset analysis included evaluation of patients who received uncrossmatched Type O FWB compared with those who received type-specific FWB.
Results A total of 488 patients received a blood transfusion. There were no significant differences in age, sex, or Glasgow Coma Scale in those who received or did not receive FWB. Injury Severity Scores were higher in patients transfused FWB. In our adjusted analyses, patients who received RBCs and FFP with FWB had improved survival compared with those who received RBCs and FFP without FWB. Of 94 FWB recipients, 46 FWB recipients (49%) were given uncrossmatched Type O FWB, while 48 recipients (51%) received type-specific FWB. There was no significant difference in mortality between patients that received uncrossmatched Type O and type-specific FWB.
Conclusions The use of FWB in austere combat environments appears to be safe and is independently associated with improved survival to discharge when compared with resuscitation with RBCs and FFP alone. Mortality was similar for patients transfused uncrossmatched Type O compared with ABO type-specific FWB in an austere setting.

AB The Blood Far Forward (BFF) research program was established to conduct blood product efficacy and safety studies, donor performance studies, and research on optimal training methods to improve the safety of blood collection and transfusion performed by Norwegian Naval Special Operation Commando soldiers. The use of intravenous fluids for volume replacement during hemorrhagic shock is controversial, but it is currently the standard of care. In the far-forward environment, large volume resuscitation for massive bleeding is a great challenge. Crystalloid and colloid solutions add weight and bulk to the medic's kit, require temperature sensitive storage, and should be warmed before infusion to prevent hypothermia. Excessive use of these solutions causes a dilutional coagulopathy, acidosis, and potentially increased inflammatory injury compared with blood products. Type-specific whole blood from an uninjured combat companion on the other hand is almost always available. It is warm, replaces intravascular volume, and provides oxygen delivery and hemostatic capacity to prevent or treat shock and coagulopathy. Whole blood may be ideal for the resuscitation of combat casualties with hemorrhagic shock. BFF program pilot studies on use of platelet-sparing leukoreduction filters, whole blood transport tolerance, donor performance, and autologous reinfusion of 24-hour ambient temperature stored whole blood have been performed and suggest the feasibility of expanding whole blood use in resuscitation. If successful, the BFF program will change tactics, techniques, and procedures with a new lifesaving capability.

AB Background Whole blood (WB) has been used in combat since World War I as it is readily available and replaces every element of shed blood. Component therapy has become standard; however, recent military successes with WB resuscitation have revived the debate regarding wider WB use. Characterization of optimal WB storage is needed. We hypothesized that refrigeration preserves WB function and that a pathogen reduction technology (PRT) based on riboflavin and ultraviolet light has no deleterious effect over 21 days of storage.
Study Design and Methods WB units were stored for 21 days either at 4 degrees C or 22 degrees C. Half of each temperature group underwent PRT, yielding four final treatment groups (n?=?8 each): CON 4 (WB at 4 degrees C); CON 22 (WB at 22 degrees C); PRT 4 (PRT WB at 4 degrees C); and PRT 22 (PRT WB at 22 degrees C). Testing was at baseline, Days 1-7, 10, 14, and 21. Assays included coagulation factors; platelet activation, aggregation, and adhesion; and thromboelastography (TEG).
Results Prothrombin time (PT) and partial thromboplastin time increased over time; refrigeration attenuated the effects on PT (p?=?0.009). Aggregation decreased over time (p?=?0.001); losses were attenuated by refrigeration (p?=?0.001). Refrigeration preserved TEG parameters (p?=?0.001) and PRT 4 samples remained within normal limits throughout the study. Refrigeration in combination with PRT inhibited fibrinolysis (p?=?0.001) and microparticle formation (p?=?0.031). Cold storage increased shear-induced platelet aggregation and ristocetin-induced platelet agglutination (p?=?0.032), as well as GPIb-expressing platelets (p?=?0.009).
Conclusion The in vitro hemostatic function of WB is largely unaffected by PRT treatment and better preserved by cold storage over 21 days. Refrigerated PRT WB may be suitable for trauma resuscitation. Clinical studies are warranted.

AB The thermodynamic properties and phase equilibria of the Cu-Hf binary system with five intermetallic compounds were studied by experiments, first-principles calculations and CALPHAD modeling. The experimental investigations included differential thermal analysis, scanning electron microscopy, energy dispersive X-ray microanalysis and micro-X-ray diffraction focusing on the 30-60 at.% Hf composition range to determine the invariant reaction temperatures. Cu10Hf7 was confirmed to melt incongruently. The enthalpies of formation of all five binary Cu-Hf compounds were predicted through first-principles calculations. The atomic configuration of one of the compounds, Cu51Hf14, was postulated through systematic first-principles calculations with 65 atoms instead of 68 atoms, denoted by hp68 in the literature. The thermodynamic description of the Cu-Hf binary system was then obtained from the new experimental data and first-principles calculations. (c) 2012 Acta Materialia Inc. Published by Elsevier Ltd.

SODIUM; PLASMA; FLUID; MASS; HYPERNATREMIA
AB Background: The water-deficit equation {WD1 = 0.6 x B-m X [1 - (140 divided by Na+)]; B-m denotes body mass} is used in medicine and nutrition to estimate the volume (L) of water required to correct dehydration during the initial stages of fluid-replacement therapy. Several equation assumptions may limit its accuracy, but none have been systematically tested.
Objectives: We quantified the potential error in WD1 for the estimation of free water (FW) and total body water (TBW) losses and systematically evaluated its assumptions.
Design: Thirty-six euhydrated volunteers were dehydrated (2.2-5.8% B-m) via thermoregulatory sweating. Assumptions within WD1 were tested by substituting measured euhydrated values for assumed or unknown values. These included the known (premorbid) Bm (WD2), a proposed correction for unknown B-m (WD3), the TBW estimated from body composition (WD4), the actual plasma sodium (WD5), the substitution of plasma osmolality (Posm) for sodium (WD6), and actual Posm (WD7).
Results: Dehydration reduced TBW by 3.49 +/- 0.91 L, 57% of which (2.02 +/- 0.96 L) was FW loss, and increased plasma sodium from 139 (range: 135-143 mmol/L) to 143 (range: 141-148 mmol/L) mmol/L. Calculations for WD1 through WD7 all underestimated TBW loss by 1.5-2.5 L (P < 0.05). WD1 through WD3 underestimated FW by 0.5 L to 1.0 L (P < 0.05), but WD6 and WD7 estimated FW loss to within 0.06-0.16 L (P > 0.05).
Conclusions: WD1 grossly underestimates TBW and FW losses. Corrections for unknowns and assumptions (WD2 through WD5) improved estimates little. The use of WD6 = 0.6 X B-m X [1 - (290 divided by Posm)] accurately estimates FW but still underestimates TBW losses by >40%. Am J Clin Nutr 2013;97:79-85.

TI Virus nomenclature below the species level: a standardized nomenclature
for natural variants of viruses assigned to the family Filoviridae
SO ARCHIVES OF VIROLOGY
LA English
DT Article
ID TAXONOMY; NAMES; IDENTIFICATION; VIROLOGISTS; EBOLAVIRUS; PROPOSAL
AB The task of international expert groups is to recommend the classification and naming of viruses. The International Committee on Taxonomy of Viruses Filoviridae Study Group and other experts have recently established an almost consistent classification and nomenclature for filoviruses. Here, further guidelines are suggested to include their natural genetic variants. First, this term is defined. Second, a template for full-length virus names (such as "Ebola virus H.sapiens-tc/COD/1995/Kikwit-9510621") is proposed. These names contain information on the identity of the virus (e.g., Ebola virus), isolation host (e.g., members of the species Homo sapiens), sampling location (e.g., Democratic Republic of the Congo (COD)), sampling year, genetic variant (e.g., Kikwit), and isolate (e.g., 9510621). Suffixes are proposed for individual names that clarify whether a given genetic variant has been characterized based on passage zero material (-wt), has been passaged in tissue/cell culture (-tc), is known from consensus sequence fragments only (-frag), or does (most likely) not exist anymore (-hist). We suggest that these comprehensive names are to be used specifically in the methods section of publications. Suitable abbreviations, also proposed here, could then be used throughout the text, while the full names could be used again in phylograms, tables, or figures if the contained information aids the interpretation of presented data. The proposed system is very similar to the well-known influenzavirus nomenclature and the nomenclature recently proposed for rotaviruses. If applied consistently, it would considerably simplify retrieval of sequence data from electronic databases and be a first important step toward a viral genome annotation standard as sought by the National Center for Biotechnology Information (NCBI). Furthermore, adoption of this nomenclature would increase the general understanding of filovirus-related publications and presentations and improve figures such as phylograms, alignments, and diagrams. Most importantly, it would counter the increasing confusion in genetic variant naming due to the identification of ever more sequences through technological breakthroughs in high-throughput sequencing and environmental sampling.

AB Objective: To evaluate the test-retest reliability of event-related power changes in the 30-150 Hz gamma frequency range occurring in the first 150 ms after presentation of an auditory stimulus.
Methods: Repeat intracranial electrocorticographic (ECoG) recordings were performed with 12 epilepsy patients, at >= 1 day intervals, using a passive odd-ball paradigm with steady-state tones. Time-frequency matching pursuit analysis was used to quantify changes in gamma-band power relative to pre-stimulus baseline. Test-retest reliability was estimated based on within-subject comparisons (paired t-test, McNemar's test) and correlations (Spearman rank correlations, intra-class correlations) across sessions, adjusting for within-session variability. Reliability estimates of gamma-band response robustness, spatial concordance, and reproducibility were compared with corresponding measurements from concurrent auditory evoked N1 responses.
Results: All patients showed increases in gamma-band power, 50-120 ms post-stimulus onset, that were highly robust across recordings, comparable to the evoked N1 responses. Gamma-band responses occurred regardless of patients' performance on behavioral tests of auditory processing, medication changes, seizure focus, or duration of test-retest interval. Test-retest reproducibility was greatest for the timing of peak power changes in the high-gamma range (65-150 Hz). Reliability of low-gamma responses and evoked N1 responses improved at higher signal-to-noise levels.
Conclusions: Early cortical auditory gamma-band responses are robust, spatially concordant, and reproducible over time.
Significance: These test-retest ECoG results confirm the reliability of auditory gamma-band responses, supporting their utility as objective measures of cortical processing in clinical and research studies.

AB Chemical warfare agents (CWAs) as well as biological toxins present a significant inhalation injury risk to both deployed warfighters and civilian targets of terrorist attacks. Inhalation of many CWAs and biological toxins can induce severe pulmonary toxicity leading to the development of acute lung injury (ALI) as well as acute respiratory distress syndrome (ARDS). The therapeutic options currently used to treat these conditions are very limited and mortality rates remain high. Recent evidence suggests that human stem cells may provide significant therapeutic options for ALI and ARDS in the near future. The threat posed by CWAs and biological toxins for both civilian populations and military personnel is growing, thus understanding the mechanisms of toxicity and potential therapies is critical. This review will outline the pulmonary toxic effects of some of the most common CWAs and biological toxins as well as the potential role of stem cells in treating these types of toxic lung injuries.

AB The objective of this study was to demonstrate that stem cells isolated from discarded skin obtained after debridement can be used with collagen and fibrin-based scaffolds to develop a tissue-engineered vascularized dermal equivalent. Discarded tissue samples were collected from severely burned patients undergoing wound debridement. Stem cells were isolated from the adipose tissue layer and their growth and immunophenotype characterized. To develop a skin equivalent, debrided skin adipose stem cells (dsASCs) were added to a collagen-polyethylene glycol (PEG) fibrin-based bilayer hydrogel and analyzed in vitro. The effect of the bilayered hydrogels on wound healing was demonstrated using an excision wound model in athymic rats. The dsASCs isolated from all samples were CD90, CD105, and stromal cell surface protein-1 positive, similar to adipose stem cells isolated from normal human lipoaspirates. Within the bilayer hydrogels, dsASCs proliferated and differentiated, maintained a spindle-shaped morphology in collagen, and developed a tubular microvascular network in the PEGylated fibrin. Rat excision wounds treated with bilayer hydrogels showed less wound contraction and exhibited better dermal matrix deposition and epithelial margin progression than controls. Stem cells can be isolated from the adipose layer of burned skin obtained during debridement. When dsASCs are incorporated within collagen-PEGylated fibrin bilayer hydrogels, they develop stromal and vascular phenotypes through matrix-directed differentiation without use of growth factors. Preliminary in vivo studies indicate that dsASC-bilayer hydrogels contribute significantly to wound healing and provide support for their use as a vascularized dermal substitute for skin regeneration to treat large surface area burns.

AB The purpose of this study was to determine whether systemic inflammatory response syndrome (SIRS) and American Burn Association (ABA) criteria predict sepsis in the burn patient and develop a model representing the best combination of novel clinical sepsis predictors. A retrospective, case-controlled, within-patient comparison of burn patients admitted to a single intensive care unit from January 2005 to September 2010 was made. Blood culture results were paired with documented sepsis: positive-sick, negative-sick (collectively defined as sick), and negative-not sick. Data for all predictors were collected for the 72 hours before blood culture. Variables were evaluated using regression and area under the curve (AUC) analyses. Fifty-nine subjects represented 177 culture periods. SIRS criteria were not discriminative: 98% of the subjects met criteria. ABA sepsis criteria were different on the day before (P = .004). The six best-fit variables identified for the model included heart rate > 130 beats per min, mean arterial pressure < 60 mm Hg, base deficit < -6 mEq/L, temperature < 36 degrees C, use of vasoactive medications, and glucose > 150 mg/dl. The model was significant in predicting positive-sick and sick, with an AUC of 0.775 (P < .001) and 0.714 (P < .001), respectively; comparatively, the ABA criteria AUC was 0.619 (P = .028) and 0.597 (P = .035), respectively. Usefulness of the ABA criteria to predict sepsis is limited to the day before blood culture is obtained. A significant contribution of this research is the identification of six novel sepsis predictors for the burn patient. (J Burn Care Res 2013;34:31-43)

MORTALITY; SCORE
AB The aim of this article was to determine the effect of cirrhosis on mortality in thermally injured adult patients. We conducted a retrospective review of patients admitted to our burn center during 2003 to 2010. Eight hundred eight patients were included in this study, of whom 24 had the diagnosis of cirrhosis established from electronic medical records and/or autopsy reports. The mortality rate for the cirrhotic patients was 50%, and for the noncirrhotic patients it was 14.8%. On logistic regression, age (odds ratio [OR], 1.08; confidence interval [CI], 1.06-1.10), TBSA (OR, 1.08; CI, 1.06-1.10), inhalation injury (OR, 3.17, CI, 1.61-6.25), and cirrhosis (OR, 8.78; CI, 2.97-25.98) had independent effects on mortality. Of the 24 cirrhotic patients in this study, the admission Model for End-Stage Liver Disease score for the patients who survived hospitalization was 12.1 +/- 4.0, and for the patients who died it was 13.8 +/- 6.0 (P = .4). When comparing patients with 10 to 50% TBSA burn, the mortality rate for cirrhotic patients was 83.3% (10/12), and for the noncirrhotic patients it was only 12.7% (50/394), P < .0001. Adults with cirrhosis are rarely able to survive burn injuries > 10% TBSA. Although we did not detect a significant association between admission Model for End-Stage Liver Disease score and death, the presence of cirrhosis is a high premorbid contributor and, therefore, new strategies are needed to improve outcomes.

DT Article
ID DONOR SKIN; TRANSPLANTATION; BURNS
AB This study provides objective data on the practice of allograft usage in severely burned patients. Furthermore, gaps in our knowledge are identified, and areas for further research are delineated. Using an institutional review board-approved protocol, active duty military patients injured while deployed in support of overseas contingency operations and treated at our burn center between March 2003 and December 2010 were identified. Their electronic medical records were reviewed for allograft use, TBSA burned, injury severity score, anatomic distribution of burns, operative burden, length of stay, transfusions, and outcome. Among 844 patients, 112 (13.3%) received allograft and 732 (86.7%) did not. The amount of allograft used per patient varied and was not normally distributed (median, 23.5; interquartile range, 69.5). Patients received allograft skin an average of 12.75 times during their admission. Allografted patients sustained severe burns (mu, 53.8% TBSA); most were transfused (71.2%) and grafted frequently, averaging every 7.45 days. Most commonly, allograft was placed on the extremities (66.5%) followed by the trunk (44.2%); however, the vast majority of allografted patients also had concomitant burns of the head (91.1%) and hands (87.5%). All-cause mortality among the allografted patients was 19.1%. In conclusion, allograft is commonly used in the surgical treatment of severe burns. Although there are no anatomic limitations to allograft placement, there are distinct patterns of use. Given the role of allograft in the acute management of large burns, there is need for further investigation of its effect on mortality, morbidity, and antigenicity. (J Burn Care Res 2013;34:168-175)

AB The purpose of this study was to evaluate the accuracy of nine predictive equations for calculating energy expenditure in severely burned adult subjects. The selected equations have been reported as commonly used or determined to be the most accurate. This prospective, observational study was conducted on adult subjects admitted between October 2007 and July 2010 with >= 20% TBSA full-thickness burns (excluding electrical burns or severe head injury). Indirect calorimetry measurements were conducted as a convenience sample during the first 30 days after injury. Demographic data were collected, and resting energy expenditure was calculated using the nine selected predictive equations and compared to measured energy expenditure (MEE) using descriptive and comparative statistics. Data were collected on 31 subjects with an average age of 46 +/- 19 years and %TBSA burn of 48 +/- 21%. For all equations, slopes and intercepts were significantly different from the line of identity when compared with MEE. A calorie-dependent bias was present for all equations, in that lower calorie range was overestimated and the higher calorie range was underestimated. Only the Carlson and Milner equations had results that were not significantly different from the MEE and mean differences that were not significant in all burn size ranges. None of the equations had a strong correlation with MEE. Of the equations available, the Milner and Carlson equations are the most satisfactory in predicting resting energy expenditure in severely burned adults when indirect calorimetry is unavailable.

AB Accurate burn estimation affects the use of burn resuscitation formulas and treatment strategies, and thus can affect patient outcomes. The objective of this process-improvement project was to compare the accuracy of a computer-based burn mapping program, Wound-Flow (WF), with the widely used hand-mapped Lund-Browder (LB) diagram. Manikins with various burn representations (from 1% to more than 60% TBSA) were used for comparison of the WF system and LB diagrams. Burns were depicted on the manikins using red vinyl adhesive. Healthcare providers responsible for mapping of burn patients were asked to perform burn mapping of the manikins. Providers were randomized to either an LB or a WF group. Differences in the total map area between groups were analyzed. Also, direct measurements of the burn representations were taken and compared with LB and WF results. The results of 100 samples, compared using Bland-Altman analysis, showed no difference between the two methods. WF was as accurate as LB mapping for all burn surface areas. WF may be additionally beneficial in that it can track daily progress until complete wound closure, and can automatically calculate burn size, thus decreasing the chances of mathematical errors.

AB Current specifications for facility handover information require contractors to produce and deliver a set of documents that provide little practical value to the facility manager. Facility managers begin their duties by rekeying the information found in these handover documents. This paper describes the facility management handover (FM) model view definition (MVD), an open-standard information exchange format that may replace current construction handover document requirements. The work was accomplished in conjunction with three buildingSMART chapters to ensure the widest possible international acceptance. The specification of the underlying industry foundation class (IFC) model with required business rules for use in the United States is called the construction-operations building information exchange (COBie) format. Procedures used to test software production and consumption of COBie were developed. Use of COBie has now been documented in several case studies. DOI: 10.1061/(ASCE)CP.1943-5487.0000196.

AB The U. S. Army is seeking to produce safer, less sensitive munitions through the addition of two new energetics, 2,4-dinitroanisole (DNAN) and N-methyl paranitro aniline (MNA), to the munitions' formula. Production of these munitions would add them to the waste stream. The use of an anaerobic fluidized-bed bioreactor (AFBB) was studied for treating these compounds in a simulated wastewater with ethanol as the electron donor. The reactor degraded both of the compounds to below detection limits over a wide range of ethanol concentrations. The degradation was found to be a transformation into secondary products for both energetics: diaminoanisole (for DNAN) and N-methyl-p-phenylenediamine (for MNA). Both of these by-products reacted upon exposure to air, forming azobond dimers. Potassium perchlorate was added to the feed stream to test if additional energetics would disrupt the transformation. The AFBB continued transformation and was able to remove the perchlorate after a two week acclimation period. The AFBB was an effective treatment method for DNAN and MNA, but further study is required to investigate the transformation products more thoroughly. DOI: 10.1061/(ASCE)EE.1943-7870.0000592.

AB The impact of mat porosity of polycaprolactone (PCL) electrospun fibers on the infiltration of neuron-like PC12 cells was evaluated using two different approaches. In the first method, bi-component aligned fiber mats were fabricated via the co-electrospinning of PCL with polyethylene oxide (PEO). Variation of the PEO flow rate, followed by selective removal of PEO from the PCL/PEO mesh, allowed for control of the porosity of the resulting scaffold. In the second method, aligned fiber mats were fabricated from various concentrations of PCL solutions to generate fibers with diameters between 0.13 +/- A 0.06 and 9.10 +/- A 4.1 mu m. Of the approaches examined, the variation of PCL fiber diameter was found to be the better method for increasing the infiltration of PC12 cells, with the optimal infiltration into the ca. 1.5-mm-thick meshes observed for the mats with the largest fiber diameters, and hence largest pore sizes.

AB Based on the Job Demands-Resources (JDR) model (E. Demerouti, A. B. Bakker, F. Nachreiner, & W. B. Schaufeli, 2001, The job demands-resources model of burnout. Journal of Applied Psychology, 86, 499-512) and Conservation of Resources (COR) theory (S. E. Hobfoll, 2002, Social and psychological resources and adaptation. Review of General Psychology, 6, 307-324), we tested three competing models that predict different directions of causation for relationships over time between family-supportive work environments (FSWE) and psychological strain, with two waves of data from a military sample. Results revealed support for both the JDR and COR theories, first in the static model where FSWE at Time predicted psychological strain at Time 2 and when testing the opposite direction, where psychological strain at Time 1 predicted FSWE at Time 2. For change models, FSWE predicted changes in psychological strain across time, although the reverse causation model was not supported (psychological strain at Time 1 did not predict changes in FSWE). Also, changes in FSWE across time predicted psychological strain at Time 2, whereas changes in psychological strain did not predict FSWE at Time 2. Theoretically, these results are important for the work family interface in that they demonstrate the application of a systems approach to studying work and family interactions, as support was obtained for both the JDR model with perceptions of FSWE predicting psychological strain (in both the static and change models), and for COR theory where psychological strain predicts FSWE across time.

AB This work enables an elegant bottom-up solution to engineer 3D microbattery arrays as integral power sources for microelectronics. Thus, multilayers of functional materials were hierarchically architectured over tobacco mosaic virus (TMV) templates that were genetically modified to self-assemble in a vertical manner on current-collectors, so that optimum power and energy densities accompanied with excellent cycle-life could be achieved on a minimum footprint. The resultant microbattery based on self-aligned LiFePO4 nanoforests of shell-core-shell structure, with precise arrangement of various auxiliary material layers including a central nanometric metal core as direct electronic pathway to current collector, delivers excellent energy density and stable cycling stability only rivaled by the best Li-ion batteries of conventional configurations, while providing rate performance per foot-print and on-site manufacturability unavailable from the latter. This approach could open a new avenue for microelectromechanical systems (MEMS) applications, which would significantly benefit from the concept that electrochemically active components be directly engineered and fabricated as an integral part of the integrated circuit (IC).

AB Subscapularis tendon tears are a well-established cause of shoulder pain. The objective of the current study was to evaluate the associated shoulder pathology in patients with full-thickness subscapularis tendon tears using magnetic resonance imaging. Forty-seven magnetic resonance imaging studies taken between 2008 and 2009 with a diagnosis of full-thickness subscapularis tendon tears were reviewed. The size of the subscapularis tendon tear, amount of muscle volume loss, Goutallier grade, biceps tendon pathology, coracohumeral distance, and associated rotator cuff tears were recorded. Statistical analysis was performed. Patients 55 years and older vs those 54 years and younger had an average subscapularis tear size of 35 vs 19 mm, an average Goutallier grade of 2.7 vs 0.8, and a total muscle volume loss of 25% vs 5%, respectively. Patients with a dislocated vs normal biceps tendons had an average subscapularis tear size of 37 vs 23 mm, an average Goutallier grade of 3 vs 0.9, and a total muscle volume loss of 28% vs 7%, respectively. Patients with vs without concomitant rotator cuff tears had an average subscapularis tear size of 32 vs 17 mm, an average Goutallier grade of 2.3 vs 0.6, and a total muscle volume loss of 21% vs 3%, respectively. Overall average coracohumeral distance measured in the axial plane was 10.8+/-4.6 mm. Average coracaohumeral distance was 14.8 vs 8.1 mm in patients with a Goutallier grade of 0 vs 3 or 4, resepectively, and 13.6 vs 8.5 mm in patients with no rotator cuff tear vs those with a supra-and infraspinatus tear, respectively.
Increased age, dislocated biceps tendons, and concomitant rotator cuff tears in patients with full-thickness subscapularis tendon tears are associated with larger subscapularis tendon tear size, higher Goutallier grades, and increased subscapularis muscle volume loss. Decreased coracohumeral distance is associated with a higher Goutallier grade and rotator cuff tears.

AB Injury to the proximal tibiofibular joint is uncommon. Previous studies regarding the anatomy of this region have predominantly focused on joint orientation. As radiographic technology has advanced, later studies have attempted to evaluate the capsular anatomy. However, no reports specifically map the ligaments to this joint. The objectives of the current study were to define specific ligamentous structures that provide stability to the proximal tibiofibular joint, describe easily identifiable and reproducible surgical landmarks to aid in surgical reconstruction, and add to the understanding of the posterolateral structures of the knee previously described by other authors.
The proximal tibiofibular joint ligaments were identified in 10 fresh-frozen cadaveric specimens. Average ligament length, width, and thickness and area of the footprints of the tibial and fibular attachments were measured. Distances from the ligament footprints to known anatomic landmarks (eg, Gerdy's tubercle, tibial articular surface, and fibular styloid) were also measured. The anterior ligament tibial attachment was a mean of 15.6 mm lateral and posterior to Gerdy's tubercle and 17.3 mm anterior and inferior from the fibular styloid. Posterior ligament tibial insertion was a mean of 15.7 mm inferior to the tibial articular surface on the tibial side and 14.2 mm medial and slightly inferior from the fibular styloid.
Definable ligaments provide stability to the proximal tibiofibular joint and can be reconstructed in an anatomic fashion using the landmarks and parameters described. This information allows for an anatomic reconstruction of the proximal tibiofibular joint, which should provide patients with better outcomes and fewer postoperative sequelae.

ID INFECTIONS; SAFETY; STATES; KENYA
AB BACKGROUND: The purpose of this study was to assess functionality and resources of facilities providing blood collection and transfusion services in Afghanistan. STUDY DESIGN AND METHODS: This national cross-sectional assessment included facilities collecting or transfusing blood identified through official data sources and private key informants. At each facility, study representatives completed a standardized instrument assessing presence of records logbook, electricity, refrigeration, and required transfusion-transmitted infection (TTI; human immunodeficiency virus, syphilis, and hepatitis B and C) test kits. Descriptive statistics were generated, with differences analyzed using chi-square or Fisher's exact tests. RESULTS: Between August and November 2010, a total of 243 facilities were surveyed with public (52.3%, n = 127) and private (43.2%, n = 105) sector comprising the majority. Most (63%) facilities were urban, with 23.5% located in Kabul province. Of 92,682 units collected nationally in the 12 months before evaluation, 7.5% (n = 6952) had no disposition record. Many (62%, n = 151) facilities had an established recordkeeping system; the remainder provided estimates. Half of surveyed facilities had regular power supply (57.8%), refrigerators for storing blood (52.3%), or all necessary TTI test kits (62.1%). Military (83.3%) and public (74.8%) facilities were more likely to have all TTI test kits present compared to private (46.7%, p < 0.01) but not nongovernmental organization (40.0%, p = 0.37) facilities. CONCLUSION: In Afghanistan, blood donation and transfusion occur with substantial differences in data recording and TTI test availability, with private facilities less likely to have these resources. Efforts are needed to improve available resources and ensure that facilities are in compliance with national standards for donor screening.

AB BACKGROUND: Availability of platelets (PLTs) is severely limited by shelf life in some settings. Our objective was to determine and compare to Food and Drug Administration (FDA) criteria the PLT recovery and survival of autologous PLTs cryopreserved at -65 degrees C or less in 6% dimethyl sulfoxide (DMSO) reconstituted with a no-wash method (cryopreserved PLTs [CPPs]) compared to autologous fresh PLTs. STUDY DESIGN AND METHODS: This was a randomized, Phase I study analyzing PLT viability and in vitro function in consenting healthy subjects. Apheresis PLTs (APs) were collected in plasma. APs were suspended in 6% DMSO, concentrated, and placed at not more than -65 degrees C for 7 to 13 days. Frozen CPPs were thawed at 37 degrees C and resuspended into 25 mL of 0.9% NaCl. Control PLTs (fresh autologous) and CPPs were labeled with 111In or 51Cr, and recovery and survival after reinfusion were determined using standard methods. A panel of in vitro assays was completed on APs and CPPs. RESULTS: After frozen storage, CPPs retained 82% of AP yield and showed increased PLT associated P-selectin and reduced responses to agonists. CPP 24-hour recovery (41.6 +/- 9.7%) was lower than for fresh PLTs (68.4 +/- 8.2%; p < 0.0001) and did not meet the current FDA criterion. CPPs had diminished survival compared to fresh PLTs (7.0 +/- 2.1 days vs. 8.4 +/- 1.2 days, respectively; p = 0.018), but did meet and exceed the FDA criterion for survival. CONCLUSION: While 24-hour recovery does not meet FDA criteria for liquid-stored PLTs, the CPP survival of circulating PLTs was surprisingly high and exceeded the FDA criteria. These data support proceeding with additional studies to evaluate the clinical effectiveness of CPPs.

ID ACROMIOCLAVICULAR JOINT DISLOCATIONS; TENDON GRAFT; INJURIES
AB Background: Modern techniques for the treatment of acromioclavicular (AC) joint dislocations have largely centered on free tendon graft reconstructions. Recent biomechanical studies have demonstrated that an anatomic reconstruction with 2 clavicular bone tunnels more closely matches the properties of native coracoclavicular (CC) ligaments than more traditional techniques. No study has analyzed tunnel position in regard to risk of early failure.
Purpose: To evaluate the effect of clavicular tunnel position in CC ligament reconstruction as a risk of early failure.
Study Design: Case series; Level of evidence, 4.
Methods: A retrospective review was performed of a consecutive series of CC ligament reconstructions performed with 2 clavicular bone tunnels and a free tendon graft. The population was largely a young, active-duty military group of patients. Radiographs were analyzed for the maintenance of reduction and location of clavicular bone tunnels using a picture archiving and communication system. The distance from the lateral border of the clavicle to the center of each bone tunnel was divided by the total clavicular length to establish a ratio. Medical records were reviewed for operative details and functional outcome. Failure was defined as loss of intraoperative reduction.
Results: The overall failure rate was 28.6% (8/28) at an average of 7.4 weeks postoperatively. Comparison of bone tunnel position showed that medialized bone tunnels were a significant predictor for early loss of reduction for the conoid (a ratio of 0.292 vs 0.248; P = .012) and trapezoid bone tunnels (a ratio of 0.171 vs 0.128; P = .004); this correlated to an average of 7 to 9 mm more medial in the reconstructions that failed. Reconstructions performed with a conoid ratio of >= 0.30 were significantly more likely to fail (5/5, 100%) than were those performed lateral to a ratio of 0.30 (3/23, 13.0%) (P < .01). There were no failures when the conoid ratio was <0.25 (0/10, 0%). Conoid tunnel placement was also statistically significant for predicting return to duty in our active-duty population.
Conclusion: Medial tunnel placement is a significant factor in risk for early failures when performing anatomic CC ligament reconstructions. Preoperative templating is recommended to evaluate optimal placement of the clavicular bone tunnels. Placement of the conoid tunnel at 25% of the clavicular length from the lateral border of the clavicle is associated with a lower rate of lost reduction and a higher rate of return to military duty.

AB We used a large population-based data set to create a clinical decision support system (CDSS) for real-time estimation of overall survival (OS) among colon cancer (CC) patients. Patients with CC diagnosed between 1969 and 2006 were identified from the Surveillance Epidemiology and End Results (SEER) registry. Low- and high-risk cohorts were defined. The tenfold cross-validation assessed predictive utility of the machine-learned Bayesian belief network (ml-BBN) model for clinical decision support (CDS).
A data set consisting of 146,248 records was analyzed using ml-BBN models to provide CDS in estimating OS based on prognostic factors at 12-, 24-, 36-, and 60-month post-treatment follow-up.
Independent prognostic factors in the ml-BBN model included age, race; primary tumor histology, grade and location; Number of primaries, AJCC T stage, N stage, and M stage. The ml-BBN model accurately estimated OS with area under the receiver-operating-characteristic curve of 0.85, thereby improving significantly upon existing AJCC stage-specific OS estimates. Significant differences in OS were found between low- and high-risk cohorts (odds ratios for mortality: 17.1, 16.3, 13.9, and 8.8 for 12-, 24-, 36-, and 60-month cohorts, respectively).
A CDSS was developed to provide individualized estimates of survival in CC. This ml-BBN model provides insights as to how disease-specific factors influence outcome. Time-dependent, individualized mortality risk assessments may inform treatment decisions and facilitate clinical trial design.

As planning continues for commercial spaceflight, attention is turned to NASA to assess whether its human system risk management approach can be applied to mitigate the risks associated with commercial suborbital and orbital flights. NASA uses a variety of methods to assess the risks to the human system based on their likelihood and consequences. In this article, we review these methods and categorize the risks in the system as "definite," "possible," or "least" concern for commercial spaceflight. As with career astronauts, these risks will be primarily mitigated by screening and environmental control. Despite its focus on long-duration exploration missions, NASA's human system risk management approach can serve as a preliminary knowledge base to help medical planners prepare for commercial spaceflights.

AB Bacillus anthracis spores are the infectious form of the organism for humans and animals. However, the approved human vaccine in the United States is derived from a vegetative culture filtrate of a toxigenic, nonencapsulated B. anthracis strain that primarily contains protective antigen (PA). Immunization of mice with purified spore proteins and formalin-inactivated spores (FIS) from a nonencapsulated, nontoxigenic B. anthracis strain confers protection against B. anthracis challenge when PA is also administered. To investigate the capacity of the spore particle to act as a vaccine without PA, we immunized mice subcutaneously with FIS from nontoxigenic, nonencapsulated B. cereus strain G9241 pBCXO1(-)/pBC210(-) (dcG9241), dcG9241 Delta bclA, or 569-UM20 or with exosporium isolated from dcG9241. FIS vaccination provided significant protection of mice from intraperitoneal or intranasal challenge with spores of the virulent B. anthracis Ames or Ames Delta bclA strain. Immunization with dcG9241 Delta bclA FIS, which are devoid of the immunodominant spore protein BclA, provided greater protection from challenge with either Ames strain than did immunization with FIS from BclA-producing strains. In addition, we used prechallenge immune antisera to probe a panel of recombinant B. anthracis Sterne spore proteins to identify novel immunogenic vaccine candidates. The antisera were variably reactive with BclA and with 10 other proteins, four of which were previously tested as vaccine candidates. Overall our data show that immunization with FIS from nontoxigenic, nonencapsulated B. cereus strains provides moderate to high levels of protection of mice from B. anthracis Ames challenge and that neither PA nor BclA is required for this protection.

AB Influenza remains a serious worldwide health threat with numerous deaths attributed to influenza-related complications. It is likely that transmission of influenza and both the morbidity and mortality of influenza could be reduced if inexpensive but reliable influenza screening assays were more available to the general public or local medical treatment facilities. This report provides the initial evaluation of a pilot system designed by Lucigen Corp. (Middleton, WI, USA) as a potential rapid near point-of-care screening system for influenza A and influenza B. The evaluation of specificity and sensitivity was conducted on stored nasal swab samples collected from emergency department patients presenting with influenza-like symptoms at a large military academic hospital and on de-identified nasal swabs and isolated RNA from a local epidemiology laboratory. The gold standard for assessment of specificity and sensitivity was the Luminex (R) Respiratory Viral Panel. Published by Elsevier Inc.

AB In this paper, we present one multi-scale integrated simulation technology for emergency preparedness with a holistic approach in hurricane, related storm surge and flood forecasting; infrastructure assessment; and emergency planning. This is an emergency management tool to aid the decision-makers and first responders in preparation for the appropriate response to an impending hurricane disaster.
Three primary models, hurricane forecasting, storm surge, and overland flooding, are executed in sequence to generate the necessary results for the proposed integrated emergency planning and preparedness tool. Two of these are open source codes in the public domain and the overland flooding model is an "in-house" code developed by the authors. Using the results of the primary models, two secondary models are executed to assess local infrastructure vulnerability and to determine the optimal evacuation routes for impacted inhabitants. The results from each model are post-processed and saved as Keyhole Markup Language (KML) files that are viewable in Google Earth for overlay analysis and decision-making. Hurricane Katrina (2005) in the Mississippi coastal area is chosen as a case study to validate the developed tool.
The models are run in sequence to generate the layers of data necessary during an actual event. The sequence is fully automated using Python and Shell scripts, which allow users to interact with each model through a series of Graphical User Interfaces. The development of technology described here would not only satisfy the scope of the project, but also be of great significance to national homeland security in the area of emergency preparedness and response.

AB Development of a robust estimator for uncertain stochastic systems under persistent excitation is presented. The given continuous-time stochastic formulation assumes norm bounded parametric uncertainties and excitations. When there are no system uncertainties, the performance of the proposed robust estimator is similar to that of the Kalman-Bucy filter and the proposed approach asymptotically recovers the desired optimal performance in the presence of uncertainties and or persistent excitation.

AB High-performance heterogeneous computers that employ field programmable gate arrays (FPGAs) as computational elements are known as high-performance reconfigurable computers (HPRCs). For floating-point applications, these FPGA-based processors must satisfy a variety of heuristics and rules of thumb to achieve a speedup compared with their software counterparts. By way of a simple sparse matrix Jacobi iterative solver, this paper illustrates some of the issues associated with mapping floating-point kernels onto HPRCs. The Jacobi method was chosen based on heuristics developed from earlier research. Furthermore, Jacobi is relatively easy to understand, yet is complex enough to illustrate the mapping issues. This paper is not trying to demonstrate the speedup of a particular application nor is it suggesting that Jacobi is the best way to solve equations. The results demonstrate a nearly threefold wall clock runtime speedup when compared with a software implementation. A formal analysis shows that these results are reasonable. The purpose of this paper is to illuminate the challenging floating-point mapping process while simultaneously showing that such mappings can result in significant speedups. The ideas revealed by research such as this have already been and should continue to be used to facilitate a more automated mapping process.

AB Purpose: Bicaval dual-lumen catheters allow for single-site cannulation venovenous extracorporeal gas exchange and facilitate early mobilization of patients. Using these catheters blood is drained from the superior and inferior venae cavae, pumped through a respiratory membrane, and returned into the right atrium. The insertion of these catheters is challenging as their correct positioning is fundamental to reduce recirculation and avoid severe complications. We describe here a new technique for the positioning of bicaval dual-lumen catheters. Materials and methods: The right internal jugular vein was percutaneously cannulated in nine sheep. The distance between skin and tricuspid valve was measured from the point of pressure change in the waveform of a Swan-Ganz catheter being retracted from the right ventricle into the right atrium. The atrium-tricuspid valve-ventricle axis was determined by observing the fluctuations of the tip of the Swan-Ganz entering the ventricle during fluoroscopy. A bicaval dual-lumen catheter was placed on the basis of these evaluations and connected to an extracorporeal respiratory support system. Results: The position of the catheter was verified at necropsy approximately 18 h after insertion. In all cases the catheter was correctly placed, with the central port situated in front of the tricuspid valve. Conclusions: The described technique may help to position bicaval dual-lumen catheters for venovenous extracorporeal gas exchange without the use of transesophageal echocardiography or contrast media during fluoroscopy.

ID INDENTATION; CERAMICS; SIZE; PENETRATION; ARMOR
AB It has long been known that a relation exists between a material's hardness and its gross impact performance; however, the nature of this relationship has not been understood to a degree useful in materials development. Many studies have shown that harder ceramics tend to display better ballistic performance. In addition, some research has suggested that a material's potential for inelastic deformation (or its quasi-plasticity a bulk property) may also play an important role in its resistance to penetration. Methods of quantifying the bulk plasticity of a ceramic material are, however, extremely limited. The current study continues an investigation into a recently proposed technique to (1) quantify bulk quasi-plasticity in SiC materials, and (2) use the plasticity value along with a hardness value to predict the transition velocity of potential armor ceramics. The transition velocity values predicted by this approach generally show excellent agreement (within 5% in most cases) with experimentally determined velocities. In addition, the robustness of this predictive technique is demonstrated through the use of multiple operators and multiple hardness testing units.

ID MECHANICAL-PROPERTIES; BAR; PARENCHYMA
AB In this study, both the dynamic shear (torsion) and axial compressive responses of porcine lung tissue were examined using modified Kolsky bar techniques. High-rate compression data were collected using a Kolsky bar with a hollow transmission bar on annular specimens at strain rates between 1000-3000 s(-1). The radial deformation of the annular specimen was recorded on a modified single loading Kolsky bar using highspeed imaging capabilities. The collected images and analysis of boundary movement indicated inhomogeneous specimen deformation induced by radial inertia, which significantly altered the desired uniaxial stress state in such high-rate compression test techniques. A novel torsion experimental technique was developed to obtain the dynamic pure shear behavior of lung tissue at shear strain rates above 500 s(-1) without inertia effects. The pure shear response was found to be two orders of magnitude weaker than the uniaxial compressive response when compared by equivalent stress-strain relations. [DOI: 10.1115/1.4007222]

AB Plantar fasciitis is a common cause of heel pain in the U. S. Army soldier, resulting in a significant loss of man hours. Given the heavy operations tempo of the U. S. military, successful treatment options need to be considered and used as quickly as possible. Plantar fasciitis can be successfully treated in up to 90% of patients using conservative measures. Operative intervention might need to be considered for those in whom conservative measures have failed. The present report is a review of 105 consecutive uniport endoscopic plantar fascial release procedures performed by the principal investigator during a 9-year period. The following data were collected and analyzed: gender, age, weight, height, body mass index, medical treatment facility, procedure laterality, preoperative pain levels, postoperative pain levels at 3 months, first ambulatory day in the controlled ankle motion boot, return to activity as tolerated, and complications. Three major points were of interest: evidence of improvement in chronic plantar fasciitis when treated with uniport endoscopic procedures; the patient attributes associated with self-reported pain levels 90 days postoperatively; and the patient attributes associated with the average time until patients were able to return to activities as tolerated in a controlled ankle motion boot. It was noted that 44.5% of those with a body mass index of 29.80 kg/m(2) or greater reported a postoperative pain level of 0; and 96.3% of those with a body mass index of 25.53 kg/m(2) or less reported postoperative pain levels of 0. The analyzed data were used to characterize the clinical outcomes of the procedure, identify changes in outcome with surgeon experience, and identify whether certain patient subgroups have better outcomes, allowing surgeons to identify which patient might be the best candidates for an endoscopic release procedure.

AB A critical assessment is carried out of the microstructural changes in respect of the associated reductions in material mechanical properties and of the attendant ballistic-impact failure mechanisms in prototypical friction stir welding (FSW) joints found in armor structures made of high-performance aluminum alloys (including solution-strengthened and age-hardenable aluminum alloy grades). It is argued that due to the large width of FSW joints found in thick aluminum-armor weldments, the overall ballistic performance of the armor is controlled by the ballistic limits of its weld zones (e.g., heat-affected zone, the thermomechanically affected zone, the nugget, etc.). Thus, in order to assess the overall ballistic survivability of an armor weldment, one must predict/identify welding-induced changes in the material microstructure and properties, and the operative failure mechanisms in different regions of the weld. Toward this end, a procedure is proposed in the present study which combines the results of the FSW process modeling, basic physical-metallurgy principles concerning microstructure/property relations, and the fracture mechanics concepts related to the key blast/ballistic-impact failure modes. The utility of this procedure is demonstrated using the case of a solid-solution strengthened and cold-worked aluminum alloy armor FSW-weld test structure.

TI Efficacy of the GluK1/AMPA Receptor Antagonist LY293558 against Seizures

AB Control of brain seizures after exposure to nerve agents is imperative for the prevention of brain damage and death. Animal models of nerve agent exposure make use of pretreatments, or medication administered within 1minute after exposure, in order to prevent rapid death from peripheral toxic effects and respiratory failure, which then allows the testing of anticonvulsant compounds. However, in a real-case scenario of an unexpected attack with nerve agents, pretreatment would not be possible, and medical assistance may not be available immediately. To determine if control of seizures and survival are still possible without pretreatment or immediate pharmacologic intervention, we studied the anticonvulsant efficacy of the GluK1 (GluR5)/alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor antagonist (3S,4aR,6R,8aR)-6-[2-(1(2)H-tetrazole-5-yl)ethyl]decahydroisoquinoline-3-carboxylic acid (LY293558) in rats that did not receive any treatment until 20 minutes after exposure to the nerve agent soman. We injected LY293558 intramuscularly, as this would be the most likely route of administration to humans. LY293558 (15 mg/kg), injected along with atropine and the oxime HI-6 at 20 minutes after soman exposure, stopped seizures and increased survival rate from 64% to 100%. LY293558 also prevented neuronal loss in the amygdala and hippocampus, and reduced neurodegeneration in a number of brain regions studied 7 days after soman exposure. Analysis of the LY293558 pharmacokinetics after intramuscular administration showed that this compound readily crosses the blood-brain barrier. There was good correspondence between the time course of seizure suppression by LY293558 and the brain levels of the compound.

AB Sulfur mustard (SM) is a vesicant chemical warfare and terrorism agent. Besides skin and eye injury, respiratory damage has been mainly responsible for morbidity and mortality after SM exposure. Previously, it was shown that suppressing the death receptor (DR) response by the dominant-negative Fas-associated death domain protein prior to SM exposure blocked apoptosis and microvesication in skin. Here, we studied whether antagonizing the Fas receptor (FasR) pathway by small-interfering RNA (siRNA) applied after SM exposure would prevent apoptosis and, thus, airway injury. Normal human bronchial/tracheal epithelial (NHBE) cells were used as an in vitro model with FasR siRNA, FasR agonistic antibody CH11, and FasR antagonistic antibody ZB4 as investigative tools. In NHBE cells, both SM (300 mu M) and CH11 (100 ng/ml) induced caspase-3 activation, which was inhibited by FasR siRNA and ZB4, indicating that SM-induced apoptosis was via the Fas response. FasR siRNA inhibited SM-induced caspase-3 activation when added to NHBE cultures up to 8 hours after SM. Results using annexin V/propidium iodide-stained cells showed that both apoptosis and necrosis were involved in cell death due to SM; FasR siRNA decreased both apoptotic and necrotic cell populations. Bronchoalveolar lavage fluid (BALF) of rats exposed to SM (1 mg/kg, 50 minutes) revealed a significant (P < 0.05) increase in soluble Fas ligand and active caspase-3 in BALF cells. These findings suggest an intervention of Fas-mediated apoptosis as a postexposure therapeutic strategy with a therapeutic window for SM inhalation injury and possibly other respiratory diseases involving the Fas response.

AB Three-dimensional manganese dioxide (MnO2)-functionalized multiwalled carbon nanotube (MWCNT) electrodes have been produced by a simple and scalable thermal decomposition process. The electrodes are prepared by treating planar MWCNT sheets with manganese(II) nitrate (Mn(NO3)(2)) solution and annealing at low temperature (200-300 A degrees C) and ambient pressure. The morphology, chemical composition, and structure of the resulting matrices have been investigated with scanning electron microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, and X-ray diffraction. Supercapacitors assembled with three-dimensional electrodes exhibit a 14-fold increase in specific capacitance (C (sp)) in comparison to those containing pristine, two-dimensional MWCNT electrodes. C (sp) varies linearly with Mn(NO3)(2) thermal decomposition temperature (from 100 to 61 F/g at 0.2 A/g), a trend that is discussed in the context of nitrate reaction chemistry and MWCNT structure. This efficient and promising approach allows for simultaneous enhancement of electrode-electrolyte contact area and incorporation of redox-based charge storage within electrochemical capacitors.

ID MAGNETIC-RESONANCE VELOCIMETRY; GAS-TURBINE AIRFOILS; COOLING
EFFECTIVENESS; CUTBACK
AB Aircraft turbine blade trailing edges commonly are cooled by blowing air through pressure-side cutback slots. The surface effectiveness is governed by the rate of mixing of the coolant with the mainstream, which is typically much faster than predicted by CFD models. Three-dimensional velocity and coolant concentration fields were measured in and around a cutback slot using a simple uncambered airfoil with a realistic trailing edge cooling geometry at a Reynolds number of 110,000 based on airfoil chord length, which is lower than practical engines but still in the turbulent regime. The results were obtained using magnetic resonance imaging (MRI) techniques in a water flow apparatus. Magnetic resonance concentration (MRC) scans measured the concentration distribution with a spatial resolution of 0.5 mm(3) (compared to a slot height of 5 mm) and an uncertainty near 5%. Magnetic resonance velocimetry (MRV) was used to acquire 3D, three-component mean velocity measurements with a resolution of 1.0 mm(3). Coupled concentration and velocity measurements were used to identify flow structures contributing to the rapid mixing, including longitudinal vortices and separation bubbles. Velocity measurements at several locations were compared with an unsteady RANS model. Concentration measurements extrapolated to the surface provided film cooling effectiveness and showed that the longitudinal vortices decreased effectiveness near the lands and reduced the average film cooling effectiveness.

AB A 2010 study exposed Staphylococcus aureus to ultraviolet (UV) radiation and thermal heating from pulsed xenon flash lamps. The results suggested that disinfection could be caused not only by photochemical changes from UV radiation, but also by photophysical stress damage caused by the disturbance from incoming pulses. The study called for more research in this area. The recent advances in light-emitting diode (LED) technology include the development of LEDs that emit in narrow bands in the ultraviolet-C (UV-C) range (100280 nm), which is highly effective for UV disinfection of organisms. Further, LEDs would use less power, and allow more flexibility than other sources of UV energy in that the user may select various pulse repetition frequencies (PRFs), pulse irradiances, pulse widths, duty cycles and types of waveform output (e.g. square waves, sine waves, triangular waves, etc.). Our study exposed Escherichia coli samples to square pulses of 272 nm radiation at various PRFs and duty cycles. A statistically significant correlation was found between E. colis disinfection sensitivity and these parameters. Although our sample size was small, these results show promise and are worthy of further investigation. Comparisons are also made with pulsed disinfection by LEDs emitting at 365 nm, and pulsed disinfection by xenon flash lamps.

AB This study determined the sensitivity of vaccinia virus, an orthopox virus commonly used as a surrogate for variola virus (etiological agent of smallpox), exposed to UVB radiation emitted by a solar simulator, or to direct natural sunlight. The data obtained indicate that: (1) the virucidal effect of natural sunlight can be mimicked adequately by an artificial light source with similar spectral characteristics in the UVB, (2) viral sensitivity to UVB or to solar radiation can be correlated with experimental data previously obtained with UVC, (3) the correlation factor between virus inactivation by solar radiation (measured at 300 +/- 5 nm) and by UVC (254 nm) is between 33 and 60, and (4) the sensitivity of viruses either dry on glass surfaces or in liquid suspension is similar when in the presence of similar amounts of cellular debris and growth media. The findings reported in this study should assist in estimating the threat posed by the persistence of virus during epidemics or after an accidental or intentional release.

TI Evaluating Sterile Human Acellular Dermal Matrix in Immediate
Expander-Based Breast Reconstruction: A Multicenter, Prospective, Cohort
Study

AB Background: Human acellular dermal matrices have gained increasing use in immediate expander-based breast reconstruction. However, some studies suggest that these grafts may be associated with a higher incidence of infection and seroma. To evaluate complication rates after matrix-based breast reconstruction, the authors conducted a prospective, multicenter, cohort study to evaluate a sterile human acellular dermal matrix in immediate expander-based breast reconstruction, specifically, to determine whether it offered a more favorable risk profile with respect to infection and seroma. A secondary purpose was to determine whether the sterilization process affects graft incorporation.
Methods: The authors performed 65 consecutive tissue expander-based breast reconstructions in a cohort of patients over a 1-year period using a single protocol. Sterile human matrix was used in all cases. The patients were evaluated for early complications (infection, seroma) and graft incorporation at the time of exchange or definitive reconstruction. Biopsies were performed in the first 20 reconstructions to provide histologic correlation of graft incorporation.
Results: Complications occurred in three breasts (4.6 percent), including one case of cellulitis (1.5 percent) and two cases of partial mastectomy flap necrosis (3.0 percent) that required debridement. There were no seromas or explantations. The grafts were incorporated in all cases and verified histologically in the first 20 biopsies.
Conclusions: Sterile human acellular dermal matrix can offer reliable matrix incorporation and a low complication rate. Sterilization does not negatively impact incorporation of the graft. The infection and seroma rates in this prospective study compare favorably to those in previous studies with nonsterilized (aseptic) acellular dermal matrix. (Plast. Reconstr. Surg. 131: 9e, 2013.)

AB Engineered fabrics are desired for military protective clothing applications. Such fabrics, exhibiting high tactile comfort, can be computationally designed. Through the use of an extensive database that contains handfeel, mechanical, construction, and tactile comfort data for fabrics, desired comfort can be predicted by measuring a limited number of properties. Output systems can be optimized to exhibit the highest level of comfort by engineering a fabric with specific properties.
Using an extensive fabric database, we identify the most significant handfeel, mechanical, and construction properties influencing tactile fabric comfort. This is done through the use of regression analysis of handfeel, mechanical, construction fabric properties, and perceived tactile comfort, using B un-standardized coefficients and Beta standardized coefficients.

AB We report experimental infection and transmission of Leishmania tropica (Wright), by the blood-feeding sand fly Phlebotomus duboscqi (Neveu-Lemaire). Groups of laboratory-reared female sand flies that fed "naturally" on L tropica-infected hamsters, or artificially, via membrane feeding device, on a suspension of L tropica amastigotes, were dissected at progressive time points post-feeding. Acquisition, retention and development of L tropica through procyclic, nectomonad, and leptomonad stages to the infective metacyclic promastigote stage, and anterior progression of the parasites from abdominal midgut blood-meal to the thoracic midgut were demonstrated in both groups. Membrane feeding on the concentrated amastigote suspension led to metacyclic promastigote infections in 60% of sand flies, whereas only 3% of P. duboscqi that fed naturally on an infected hamster developed metacyclics. Sand flies from both groups re-fed on naive hamsters, but despite infections in 25-50% of membrane-fed and 2-3.5% of naturally fed flies, no skin lesions developed in the hamsters. After four months of observation these animals were euthanized and necropsied. Screening of the organs and tissue by polymerase cinain reaction (PCR) that targeted the small subunit RNA gene, amplified generic Leishmania DNA from liver, spleen, bone marrow, and blood, but only from hamsters bitten by membrane-infected P. duboscqi. These results are notable in demonstrating the ability of P. duboscqi, originating from Kenya, to acquire, retain, develop, and transmit a Turkish strain of L tropica originally isolated from a human case of cutaneous leishmaniasis. This marks the first demonstration of complete development and transmission of L tropica by a member of the Phlebotomus subgenus of sand flies. Published by Elsevier B.V.

AB Introduction: Hypermetabolism is universal in the severely burned and is characterized by catabolism of lean mass and body fat with associated insulin resistance. Adipokines are likely to play a role in these changes but have not been identified to date in burn patients.
Methods: From a single burn ICU, 17 burn patients with an expected stay >14 days were studied. Study period began within 14 days of admission. Over 7 days, plasma samples were collected for measurement of leptin, adiponectin, resistin, ghrelin, insulin, and cortisol by ELISA. For comparison, samples from 15 healthy controls of similar age, BMI, and blood glucose were obtained.
Results: Mean age was 33 +/- 17 years and BMI 26 +/- 3.4. Average burn size was 45 +/- 20% TBSA and ISS 32 +/- 10 with 72% having inhalation injury; in-hospital mortality was 29%. Estimated energy needs were 3626 +/- 710 kcal, of which 84 +/- 21% were met by enteral feeding with intensive insulin treatment (glucose 80-110 mg/ml). Using the homeostasis model assessment of insulin resistance, burned subjects were more resistant than controls (17 +/- 11.3 and 8 +/- 10.0). Insulin levels were elevated (57 +/- 35.6 mu U/ml in burned subject vs. 26 +/- 31.1 mu U/ml in controls), and cortisol concentrations increased (50 +/- 41.2 mu g/dl vs. 12 +/- 3.9 mu g/dl). These traditional hormone changes were associated with increased resistin (16.6 +/- 5.5 ng/ml vs. 3.8 +/- 0.9 ng/ml) and decreased leptin (8.8 +/- 8.9 ng/ml vs. 19.4 +/- 23.5 ng/ml), adiponectin (9 +/- 3.5 ng/ml vs. 17 +/- 10.2 ng/ml), and ghrelin (0.37 +/- 0.14 ng/ml vs.0.56 +/- 0.26 ng/ml).
Conclusion: Patients with burns, who are characteristically hypermetabolic with hypercortisolism and insulin resistant, have significant changes in adipokine levels that appear independent of the magnitude of initial injury or metabolic derangement. In addition, suppression of ghrelin in the presence of decreased leptin and adiponectin levels in combination with increased insulin and resistin levels represent unexpected changes in the metabolic milieu of the injured patient possibly due to dramatic activation of inflammatory pathways, indicating strategies for treatment.

AB Various international and national regulations hold polluters liable for the cleanup of released hazardous substances and the restoration/rehabilitation of natural resources to preincident baseline conditions, a process often referred to as natural resource damage assessment and restoration (NRDAR). Here, we, the authors, describe how global climate change (GCC) will challenge each of the steps of NRDAR processes and offer eight recommendations to improve these processes in light of GCC. First, we call for a better understanding of the net effects of GCC and contaminants on natural resources. Second, we urge facilities and environmental managers to plan for GCC-related factors that are expected to increase the probability of contaminant releases. Third, we suggest re-evaluating definitions of baseline and reference conditions given that GCC will alter both their trajectories and variability. Fourth, we encourage long-term monitoring to improve the quantification of baseline conditions that will change as climate changes. This will enhance the accuracy of injury assessments, the effectiveness of restoration, and the detection of early warning signs that ecosystems are approaching tipping points. Fifth, in response to or anticipation of GCC, restoration projects may need to be conducted in areas distant from the site of injury or focused on functionally equivalent natural resources; thus, community involvement in NRDAR processes will be increasingly important. Sixth, we promote using NRDAR restoration projects as opportunities to mitigate GCC-related impacts. Seventh, we recommend adaptive management approaches to NRDAR processes and communication of successes and failures widely. Finally, we recommend focusing on managing the stressors that might be exacerbated by GCC, such as pollution and habitat loss, because there is a long history of successfully mitigating these stressors, which can be more easily managed on local scales than climate change. We believe that adoption of these recommendations will lead to a more efficacious NRDAR process, despite the challenges posed by climate change. Environ. Toxicol. Chem. 2013;32:93101. (c) 2012 SETAC

Acute mountain sickness (AMS) and large decrements in endurance exercise performance occur when unacclimatized individuals rapidly ascend to high altitudes. Six altitude and hypoxia preacclimatization strategies were evaluated to determine their effectiveness for minimizing AMS and improving performance during altitude exposures. Strategies using hypobaric chambers or true altitude were much more effective overall than those using normobaric hypoxia (breathing, <20.9% oxygen).

DE Sodium-cooled fast reactor; ERANOS; VISION; Fast reactor recycle;
Multi-tiered recycle
AB The Sodium-Cooled Heterogeneous Innovative Burner Reactor (SCHIBR) model created at the University of South Carolina uses heterogeneous minor actinide targets. To improve minor actinide transmutation, a hybrid fuel management scheme is utilized involving initially moderated assemblies on the core periphery followed by a second period of irradiation in a fast flux with the moderating rods removed. A multi-tiered recycling strategy was developed to increase plutonium utilization in the SCHIBR model through the recycle of the driver fuel. An equilibrium fuel cycle was evaluated with the computer code ERANOS to determine the improvements in fuel utilization, reduction in high level waste, and safety of the SCHIBR design. Fuel depletion studies were conducted to determine the composition of input and output streams in order to develop reactor recipes for use in the fuel cycle simulation code, VISION. The once-through SCHIBR model reduces the radiotoxicity of high level waste by 66% of the once-through LWR model after 300 years in storage. The multi-tiered recycling strategy offers improvements over the previous once-through SCHIBR model by reducing the radiotoxicity by 86% after 300 years in storage. (C) 2012 Elsevier Ltd.

AB Evidence of an actual or perceived gap in ideological beliefs between civilian and military communities informs current debates on the military and its relationship to broader society. The authors examine one cohort of the military and its members' perception of their own ideology in relation to their civilian counterparts using a 2009 survey of cadets at the United States Military Academy. The authors ascertain cadet perceptions of (1) cadet ideological leanings on individual and aggregate levels, (2) the ideological leanings of the civilian population, and (3) the civilian population's assessment of the military's ideological leanings. The authors attempt to discern whether or not this military subpopulation perceives itself as different from the rest of society. The authors find that while members of the Army's future officer corps perceive themselves as more conservative than their civilian peers and society writ large, as a group they hold rather moderate political views.

AB A series of 36 synthetic antimicrobial peptides containing unnatural amino acids were screened to determine their effectiveness to treat Enterococcus faecium, Staphylococcus aureus, Klebsiella pnemoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species (ESKAPE) pathogens, which are known to commonly infect chronic wounds. The primary amino acid sequences of these peptides incorporate either three or six dipeptide units consisting of the unnatural amino acids Tetrahydroisoquinolinecarboxylic acid (Tic) and Octahydroindolecarboxylic acid (Oic). The Tic-Oic dipeptide units are separated by SPACER amino acids with specific physicochemical properties that control how these peptides interact with bacterial cell membranes of different chemical compositions. These peptides exhibited minimum inhibitory concentrations (MIC) against these pathogens in the range from >100 to 6.25 mu g/mL. The observed diversity of MIC values for these peptides against the various bacterial strains are consistent with our hypothesis that the complementarity of the physicochemical properties of the peptide and the lipid of the bacteria's cell membrane determines the resulting antibacterial activity of the peptide.

AB Recent interest in bio-inspired materials has led to the development of techniques that can be used to synthesize hierarchical structures with controlled morphology and mineralogy. One such technique investigated in this study consists of the use of electromigration and electrodeposition techniques to deposit mineral phases with controlled morphology and mineralogy by infilling a predefined porous templates. Here, the utility of precipitating various polymorphs of calcium carbonate in three-dimensional templates is demonstrated. Applied potentials and times were varied while scanning electron microscopy and X-ray diffraction were used to determine polymorph formed and its morphology. It was found that higher applied potentials and shorter operating times resulted in the formation of metastable polymorphs of calcium carbonate (e.g., vaterite) that infilled the porous media. Results provide insights for developing bio-inspired composite materials for various structural and medical applications, such as synthetic bone.

AB Background: The American Academy of Orthopaedic Surgeons position statement on the treatment of pediatric femoral shaft fractures could not comment on the safety of flexible intramedullary (IM) rod removal because of a lack of published evidence. This study reviews the acute complications of flexible IM rod removal from pediatric patients treated for femoral shaft fractures.
Methods: A retrospective clinical and radiographic analysis at a single institution over a 5-year period. Demographic and radiographic parameters were analyzed to determine their influence on intraoperative and immediate postoperative complications.
Results: One hundred sixty-three subjects (133 males, 30 females), mean age of 9.3 +/- 2.8 years (range, 2.7 to 14.8 y) and mean weight of 34.4 +/- 15.3 kg (range, 14.0 to 139.0 kg), underwent femoral flexible IM rod removal a mean 12.4 +/- 10.8 months (range, 2.4 to 63.8 mo) after placement with mean operative time of 51.1 +/- 22.3 minutes (range, 10 to 131 min). One hundred fifty-one subjects (92.6%) had stainless-steel Ender rods and the remaining nails were titanium. There were no significant demographic, intraoperative, or radiographic differences comparing subjects with Ender versus titanium rods. Indications for rod removal were pain at insertion site, family request, or surgeon's recommendation. There were 4 (2.5%) minor intraoperative difficulties, including the inability to remove 1 of 2 rods secondary to IM migration (n = 1) and complete bone overgrowth at insertion site resulting in prolonged extraction time (n = 3). Three of the 4 subjects had the rods placed >60 months before removal. Immediately postoperative (n = 134), there were 4 (3.0%) complications, including superficial wound infection (n = 3, 2.2%) and knee contracture (n = 1, 0.8%). Subjects were released to full activities at a mean 4.7 +/- 1.8 weeks postoperatively with no known postoperative fractures.
Conclusions: The rate of intraoperative and immediate postoperative complications is low. Neither patient demographics, fracture characteristics, nor operative technique influenced the complication rate. Intraoperative difficulties may be minimized with removal of rods before signs of overgrowth.

AB Background: There is an increased risk of specimen labeling errors with the generation of a high volume of pathology specimens. Measuring specimen labeling accuracy has been suggested as a possible measure for patient safety.
Objective: We sought to identify operational areas for improvement around specimen handling with the institution of a standardized specimen labeling protocol in the Duke University Medical Center Department of Dermatology. The average rates of specimen labeling events before and after implementation of this protocol were analyzed to determine the efficacy of this systematic approach.
Methods: We collected the monthly aggregated rates of specimen labeling events occurring with skin specimens processed through the Duke University Medical Center Department of Pathology from December 2008 through June 2011. The average monthly rates of events per 1000 cases for the time periods from December 2008 through March 2010 and June 2010 through September 2011 were compared.
Results: The data collected showed a statistically significant decline in the average monthly rate of specimen labeling errors after institution of the protocol. Before implementation, specimen labeling events occurred at a rate of 5.79 events per 1000 with a decrease to 3.53 events per 1000 after integration of this system (P = .028).
Limitations: Limitations of this study include possible sampling error and regression toward the mean.
Conclusions: Low-cost, process-driven interventions are effective in the reduction of specimen handling errors. (J Am Acad Dermatol 2013;68:53-6.)

AB Large-scale rodent control can help to manage endangered species that are vulnerable to invasive rodent consumption. A 26 ha rodent snap-trap grid was installed in montane forest on Oahu Island, Hawaii, in order to protect endangered snails and plants. To assess the effectiveness of this trapping operation in reducing fruit consumption and seed predation of the endangered Hawaiian lobeliad, Cyanea superba subsp. superba, pre- and post-dispersal C. superba fruit consumption were monitored for 36 plants at the site with rodent control (Kahanahaiki) and 42 plants at an adjacent site without rodent control (Pahole). Over 47 % of all monitored fruit were eaten on the plants at Pahole compared to 4 % at Kahanahaiki. Images captured using motion-sensing cameras suggest that black rats (Rattus rattus) were the only pre-dispersal fruit consumers. To quantify post-dispersal fruit consumption, and to identify the culprit frugivore(s), mature fruit were placed in tracking tunnels positioned on the forest floor and checked daily. At Pahole, all of the fruit were consumed by rats compared to 29 % at Kahanahaiki. Lastly, to determine if rodents from the sites were predators or dispersers of C. superba seed, fruit were fed to captive black rats and house mice (Mus musculus). Black rats consumed entire fruit, killing all the seed, while mice did little damage to the fruit and seed. Therefore, large-scale rat trapping can directly benefit the reproduction of C. superba subsp. superba. Controlling black rats at restoration sites appears integral to the successful restoration of this endangered plant species.

AB In this paper the effects of projectile size and shape on the impact response of a single-layer fully-clamped flexible woven fabric are numerically studied using a finite element analysis. Six projectiles of spherical, cylindrical, and conical shapes with varying sizes but of the same mass are considered. A yam-level fabric model with a deterministic implementation of experimental mean yarn tensile strength and inter-yarn friction is considered. A single impact velocity is chosen for the six different projectiles to compare the fabric impact responses in terms of residual projectile velocities, fabric energy dissipations, and number of failed yarns. Two impact locations are considered, at a yarn cross-over and at the gap in-between the yarns. The sensitivity of fabric impact response to projectile geometrical characteristics and impact location is demonstrated. (c) 2012 Elsevier Ltd. All rights reserved.

AB Crosslink density is one of the important parameters that govern the physical properties of fiber reinforced polymer (FRP) composites. Enhancement of crosslink density by effective matrix modification through nanoparticle incorporation is the most prominent way to improve mechanical and thermo-mechanical properties of FRP composites. In this study, at first, 0.1-0.4 wt.% amino-functionalized multi-walled carbon nanotubes (NH2-MWCNTs) were incorporated in SC-15 epoxy system and the variation in crosslink density was investigated using rubber elasticity theory. Subsequently, the effect of these MWCNTs on interlaminar shear strength (ILSS) of e-glass/epoxy composites was studied. Result obtained from the tests showed a linearly increasing trend in crosslink density and ILSS properties from 0 to 0.3 wt.% MWCNTs loading. Better dispersion of MWCNTs facilitated more crosslinking sites, whereas, the three-way reaction between amine functional groups of MWCNTs with epoxide groups of resin and epoxy silanes of fiber surfaces improved the crosslinking and thereby ILSS properties of e-glass/epoxy composites.

AB We analyzed 91 relict grain-bearing micrometeorites (MMs) from two Antarctic collections: Tottuki icefield and the South Pole Water Well. To determine if the MMs are related to specific meteorite groups, we analyzed their relict olivines and low-Ca pyroxenes and compared them with olivines and pyroxenes we analyzed in various meteorites: an enstatite chondrite (EH3), a suite of carbonaceous chondrites (CM2, CR2, CV3.2, CO3.0, and CO3.2), an ungrouped carbonaceous chondrite (Tagish Lake), various unequilibrated ordinary chondrites (H3.2, L3.7, LL3.0, LL3.2, LL3.3), and a Rumuruti chondrite (R3.5/5 breccia).
Mg-rich olivines are the most common relict mineral in the MMs studied (42%), followed by Fe-rich olivines (16%), Mg-rich low-Ca pyroxenes (15%), and MMs containing both Mg-rich olivine and low-Ca pyroxene (13%). If one corrects for the effects of atmospheric heating on the proportion of olivines and pyroxenes, then 59% of MMs are related to carbonaceous chondrites, 22% to ordinary chondrites (mostly unequilibrated, UOCs), and 19% to a high-Mn group. Results of textural observations suggest that four MMs resemble chondrules from CO3 carbonaceous chondrites, and one is a shock-melted H chondrite. MMs from the high-Mn group appear to have crystallized from a melt and might be fragments of chondrule-like objects similar to those found in comet 81P/Wild 2. (C) 2012 Elsevier Ltd.

AB OBJECTIVE. Occupational exposures to blood and other bodily fluids occur in approximately 5 per 100 persons every year in US hospitals. Since the provision of health care in the deployed environment poses unique challenges to hospital personnel, it is important to characterize the rates of occupational exposures and understand the prevalence of blood-borne pathogens (BBPs) in host nations.
METHODS. A retrospective review of public health and laboratory records at a US military trauma center in Afghanistan from October 1, 2010, to March 31, 2012.
RESULTS. A total of 65 occupational exposures were reported, including 47 (72%) percutaneous and 18 (28%) mucocutaneous, with a yearly rate of 8.6 exposures per 100 persons. During 6-month deployment cycles, the majority of exposures (46.2%) occurred in the first 2 months after arrival in Afghanistan. Physicians reported the most exposures (26%), and the operating room (48%) was the most common hospital location. The prevalence of hepatitis B and hepatitis C among local national source patients (n = 59) was 8.9% and 2.3%, respectively, with no cases of HIV or syphilis detected. In contrast, there were no BBPs detected in coalition source (n = 12) or exposed (n = 57) patients.
CONCLUSIONS. The characteristics of occupational exposures in this deployed environment were comparable to those of US-based hospitals. Standard practices used to reduce occupational exposures, such as use of personal protective equipment and safety devices, should continue to be prioritized in the deployed setting. Although BBP rates are not well defined in Afghanistan, our results were consistent with those of prior epidemiologic studies. Infect Control Hosp Epidemiol 2013;34(1):74-79

ID DYNAMIC ANALYSIS; BEAM
AB The focus of this paper is on establishing a robust signal processing approach for damaged vehicles (i.e., cracked structures) with structural variability such as thicknesses of various components and Young's modulus variations. The approach assumes that vibration-type data is collected during the operation of a vehicle. Next, the collected data is used in a novel combined sensor selection and signal processing methodology. The new methodology resolves two key issues for complex structures with variability: (i) decides which field data channels are statistically optimal to be used, and (ii) establishes which data channels should correlate and how. The overall algorithm is based on a generalised version of the effective independence distribution vector. Also, the correlations among channels are used for noise rejection. Furthermore, the dynamics of the vehicle (i. e., a complex structure with variabilities) is modelled using Parametric Reduced Order Models (PROMs) and the concept of bilinear mode shapes introduced recently by the authors for cracked structures. PROMs are used to address the presence of variability and account for their effects on the data collected from various channels. The bilinear modes are used to capture the effects of the crack. The proposed methodology is demonstrated for a complex/realistic model of a HMMWV frame with parameter variability and a crack.

AB The degree to which an Internet-Distributed Hardware-In-the-Loop (ID-HIL) simulation loses fidelity relative to the single-location alternative is referred to as distortion. This paper shows that, besides delay, the choice of coupling point, i.e., the port at which the system model is integrated across the Internet, also affects distortion. To quantify distortion, a frequency-domain metric is proposed using a linear systems framework. This metric is then used to analyse how the choice of coupling point affects distortion, leading to guidelines for selecting a coupling point that gives minimal distortion. The theory is demonstrated on a quarter-car model.

AB This paper proposes a battery power management strategy using Critical Surface Charge (CSC) information estimated by Extended Kalman Filter (EKF) in real time. The insight from CSC characterisation is used to propose a novel approach for supervisory control design of a series Hybrid Electric Vehicle (HEV). The underlying phenomenon determining the battery allowable power limits is closely connected to the CSC. The estimated CSC is processed with a Finite Impulse Response (FIR) filter to smoothen short-term fluctuations and highlight longer-term trajectories. The battery allowable power limits are adjusted based on the filtered CSC information to prevent undesirable battery operations.

ID OPTIMIZATION; STIFFNESS
AB The need exists for robust and efficient optimal design methods for application to multibody systems, in which the components to be designed represent connections between large displacement, large rotation motions of the subsystems' bodies. One specific application is occupant restraint systems, such as the Gunner Restraint System (GRS), in which both the vehicle and the gunner can undergo large relative and absolute motions under extreme driving or external threat conditions. In addition, the restraint/connection components can have amplitude-dependent, time-dependent, and timing-dependent behaviour, such as an active belt retractor. Current optimisation methodologies are ill suited for this problem, suffering from infeasibility, lack of robustness, and/or high computational expense. This paper presents an extension of topology optimisation techniques to consider multibody dynamics systems and to treat a much more open design space, which can include passive, active, and reactive structures/devices. The objective is to obtain an optimally combined structural and material system, considering the best use of passive, active and reactive members.

AB Military ground vehicle design must consider the threat posed by underbody blasts to new vehicles and their occupants, while also accounting for weight reduction goals for improving fuel economy and mobility. A two-stage process is presented to model the blast event, using LS-DYNA for simulating vehicle response and MADYMO for the occupant's response. Issues including computational expense, objective function formulation and multi-objective seating system design optimisation are addressed in detail, and three different blastworthiness optimisation formulations are presented and evaluated.

Specifically, we present the three major building blocks of our framework: (1) the introduction of an appropriate validation metric for dealing with the multivariate functional data that are the output of dynamic vehicle systems; (2) the robust implementation of a Bayesian interval-based hypothesis testing technique for quantifying the confidence in simulation models used for design under uncertainty; (3) the development of a sequential design optimisation and calibration-based validation methodology that addresses the inadequacy of current validation practices in simulation-based design optimisation. We present a simple yet illustrative example and discuss the techniques being developed currently that will complete the proposed framework.

AB Background: Complement is invariably activated during trauma and contributes to tissue injury. Recombinant human decay-accelerating factor (DAF), a complement regulatory protein that inhibits both classical and alternative pathways, improves survival and reduces tissue damage in animal models of tissue injury. The extent to which DAF may facilitate resuscitation in hemorrhaged large animals is not known.
Methods: Male Yorkshire swine assigned to one of six groups were subjected to controlled, isobaric hemorrhage over 15 min to a target mean arterial pressure (MAP) of 35 mm Hg. Hypotension was maintained for 20 min followed by a bolus intravenous injection of DAF or vehicle followed by Hextend resuscitation. Animals were observed for 3 h after hypotensive Hextend resuscitation. Survival, blood chemistry, and physiological parameters were recorded. Additionally, tissue from lung, small intestine, liver, and kidney were subjected to histopathologic evaluation and tissue deposition of complement proteins was determined by immunohistochemistry, dot-blot, and Western blot analyses.
Results: Administration of DAF (25 mu g/kg) to animals subjected to hemorrhage prior to Hextend infusion significantly improved survival (73% versus 27%); protected gut, lung, liver, and kidney tissue from damage; and resulted in reduced resuscitation fluid requirements when compared with animals subjected to hemorrhage and resuscitation with Hextend alone. Animals treated with a higher dose of DAF (50 mu g/kg) followed by Hextend fluid resuscitation did not experience the same benefit, suggesting a narrow therapeutic range for use of DAF as adjunct to Hextend fluid.
Conclusion: DAF improved survival and reduced early Hextend fluid resuscitation requirements in swine subjected to hemorrhagic shock. These benefits are attributed to decreased complement deposition and limited organ damage. Published by Elsevier Inc.

AB Introduction: Hemorrhage alone without concomitant trauma often results in a hypercoagulable state that makes it difficult to prevent clotting within the blood withdrawal catheters. Although systemic administration of heparin can ameliorate this problem, heparin use has many additional actions that may confound interpretation of the hemorrhage experiments. The problem can be resolved by the use of a dual lumen catheter that anti-coagulates only the blood within the withdrawal circuit. We describe the design of such a catheter and evaluate its function in studies of hemorrhagic shock in rats.
Materials and methods: Construction directions are provided for the dual lumen catheter along with a commercial source. The catheters were connected to computer controllable infusion syringes. Either citrate or heparin was used for regional extracorporeal anticoagulation. Rats were anesthetized and hemorrhaged to 40 mm Hg for more than 15 min through the use of a computer program written in Labview. Ionized calcium measurements were obtained pre- and posthemorrhage.
Results: The catheters remained patent throughout the experiments. There was no significant difference in the ionized calcium whether citrate or heparin was used for extracorporeal anticoagulation.
Conclusion: The dual lumen catheters are suitable for the study of hemorrhagic shock in rats without the need for systemic anticoagulation. The catheters can be used with computer-controlled hemorrhage procedures. (C) 2013 Elsevier Inc. All rights reserved.

ID MANAGEMENT
AB A temporary coalition is often formed to pursue a common goal based on the collaboration of multiple partners who may have their own objectives. The coalition network must attain multiple objectives, under resource constraints and time deadlines. We propose a task assignment algorithm for a scenario where tasks are dynamic, with different arrival times and deadlines. We propose a heuristic coalition formation technique that uses multiple dimensions of trust (i.e., integrity, competence, social connectedness, and reciprocity) to assess trust of each entity. The proposed scheme enables task leaders to make critical assignment decisions based on assessed trustworthiness of entities. We consider three different objectives, namely, maximizing resilience and resource utilization while minimizing delay to task completion. We devise a ranking-based heuristic with linear runtime complexity to select members based on risk derived from trust assessment of nodes. We validate the performance of our proposed scheme by comparing our scheme with a non-trust-based baseline scheme as well as a global optimal solution implemented with the Integer Linear Programming technique.

DE Synthetic aperture radar (SAR); rate up-conversion; low-rank matrix
completion; robust PCA
AB The radar data to form synthetic aperture radar (SAR) imagery is normally transmitted and received by moving platforms like aircraft or vehicles. In many situations, the platforms move at high speed; which reduces the number of sampling records collected to the synthetic aperture, hence degrades the quality of the reconstructed SAR images. Therefore, it is necessary to develop an algorithm that is capable of increasing the temporal frequency rate of the received data. In this paper, we propose a novel technique to generate intermediate records from the existing ones by a locally-adaptive low-rank matrix recovery framework. The system first fills in the blank records using a bi-directional motion estimation scheme. The initialized aperture records are then refined by a robust low-rank matrix completion algorithm using the reference from neighborhood clean records. Experiments demonstrate that the proposed method provides comparative results when up-converting the aperture rate by a factor of two or four, both in mean square error of the raw SAR signal and PSNR performance of the recovered SAR images.

AB Slow-light effect has potential for applications ranging from optical information processing to optical switching. It is well-known that material dispersion can induce slow-light near some resonances, such as electromagnetically induced transparency. Additionally, structural dispersion can also be applied to realize slow-light, e.g. photonic crystal waveguides (PhCWs). Here we study the Bloch modes of a silicon periodic waveguide with an ultra-large hollow-core. With three-dimensional fully-vectorial calculations, we successively find that the proposed periodic waveguide can support guided Bloch modes (below the air light line). Moreover, this cage waveguide is quite flexible for geometric tailoring of dispersion relation, and can be a promising device for integrated nanophotonics.

We develop a novel model-based approach to identify the best protocol setting under which trust bias is minimized, that is, the peer-to-peer subjective trust as a result of executing our distributed trust management protocol is close to ground truth status over a wide range of operational and environment conditions with high resiliency to malicious attacks and misbehaving nodes.

AB Structured, competition-based learning activities have been used in the process of educating aspiring civil engineers for many years. Some of the better known and more widely adopted intercollegiate competitions include the American Society of Civil Engineers' Concrete Canoe Competition and the American Society of Civil Engineers/American Institute for Steel Construction's National Steel Bridge Competition. Beyond these common competitions, it is estimated that upwards of 38 additional competitions, sponsored by various organizations, are in use to varying extents by civil engineering programs throughout the United States.
Data collected during this study enabled a thorough investigation of national and regional civil engineering competitions. A detailed analysis of each identified competition has been performed by the investigation team. In addition, a survey of ABET, Inc. accredited civil engineering programs heads was performed to capture the frequency and distribution of individual competitions, as well as an assessment of the department heads' perceived educational value to the participants of each competition. An existing, well-established, and validated education metric has been used as the tool by which each competition is evaluated.
Given the resource investment required to participate in many of the competitions currently in use, it is anticipated that the results of this study will be of interest to civil engineering program administrators, faculty members, sponsoring agencies associated with current competitions, and developers of future civil engineering competitions.

AB Summer immersive experiences for undergraduate students in Aeronautical and Mechanical Engineering programs come in varied forms and can represent a substantial effort by staff and faculty, as well as considerable financial resources to coordinate. Experiences range from work in governmental laboratories and research centers to collaboration with industry partners, and may include graduate research at distant academic locations. This study seeks to evaluate the utility of these work experiences, measuring their effectiveness across ABET program outcomes and assessing their contribution to student learning and motivation to continue to learn. A survey of 53 students who conducted immersive experiences related to Aeronautical and Mechanical Engineering disciplines from the United States Air Force Academy and the United States Military Academy has been conducted. Survey results are analyzed to determine the overall value provided by the experience as measured across program outcomes outlined in ABET criteria 3 (a-k). The unique contributions available from the experience are balanced with the administrative requirements to suggest a best practice in leveraging the most from these experiences and to assist programs that might consider initiating or refining their own participation in similar programs.

AB In the Computer Aided Design ( CAD) course at the United States Military Academy ( West Point, NY), students learn two different design software packages, SolidWorks (TM) and MATLAB (TM). In the past, faculty members who are responsible for teaching the course have observed a difference in performance by the students in course homework assignments and examinations between the two applications. In general, students performed higher on SolidWorks assignments. This poses the question: Does learning style preference affect the ability to learn different computer aided design tools?
One hundred and eleven students enrolled in either the Spring 2012 (n = 61) or Fall 2013 (n = 50) semesters of Computer-Aided Design were asked to participate in this Institutional Review Board exempted study. Each student was asked to take Felder's and Soloman's "Index of Learning Styles" questionnaire(1). Of the four learning dimensions that are evaluated in the questionnaire, only the scores for two, Visual versus Verbal and Sequential versus Global, were examined in this study. These two dimensions seem to be most relevant to the research question. We expected that SolidWorks was more suited to learners who tend to be more visually and globally-oriented. Conversely, we expected MATLAB to be more suited for more verbally and sequentially-oriented students.
This paper discusses the results of our study. The raw data in the Visual/Verbal domain appear to support our hypothesis to suggest that verbal learners perform better in MATLAB programming than in SolidWorks modeling, whereas visual learners have a less distinct difference in performance. A survey of students also indicates that a higher percentage of verbal learners prefer MATLAB compared to their visual counterparts.

AB The American Institute of Steel Construction (AISC) and American Society of Civil Engineers (ASCE) Steel Bridge and ASCE's Concrete Canoe competitions are a staple of civil engineering education. These two competitions provide a technical design problem for students to solve under very tight performance requirements, solution envelopes, and evaluation standards which tend to drive competitors to similar, optimized solutions. In contrast to these highly structured problems, both the National Academy of Engineering (NAE) and the American Society of Civil Engineers (ASCE) report that the engineer of the 21st Century will also be called upon to solve extremely complex, daunting, and ill-structured problems. The authors and their institutions are currently developing the Goethals Infrastructure Challenge as a new student competition built around solving the social-technical, complex adaptive, and 'wicked' problems associated with designing, constructing, operating and maintaining the world's infrastructure. This paper explains the organization of the Goethals Infrastructure Challenge, the student learning objectives for participating in the challenge, the annual process used to formulate the challenge, required funding mechanism, submission procedures, judging and evaluation plans, and budgeting and funding. In addition to being educational, this competition is designed to inspire a new generation of engineers to address the challenges we face in "restoring and improving urban infrastructure" and "providing access to clean water" as suggested by the NAE, managing the $2.2 trillion necessary to improve our infrastructure, and defining what infrastructure should be and do when functioning optimally in the knowledge-based, global economy of the 21st Century. For this reason, the challenge is named for George Washington Goethals who, with the building of the Panama Canal, transformed 20th Century infrastructure in the hope that this event will inspire the participants and the engineering profession to transform the 21st Century infrastructure in a similar way.

AB Many universities have real environmental problems in areas such as energy efficiency, water efficiency, and solid waste management, but do not always have the time or resources to examine the problems in depth. The United States Military Academy (USMA) employs an introductory environmental engineering and science course required for environmental engineering and environmental science majors, which is taken during the first semester of their junior year. Additionally, USMA requires that all non-engineering majors take a three-course engineering sequence, and a slightly modified version of the introductory course is taught each year to approximately 170 such students in the first semester of their junior year. Within the context of the course, we maintain a semester-long term project that examines real environmental problems, which our student teams (3-4 students of varying academic majors) observe or clients (such as the Department of Public Works or our student government) identify. Preparation for the project requires student teams to develop a hypothesis and a basic sampling and evaluation protocol. Students then use the protocol to conduct sampling in the local community and analyze results in light of their hypothesis. Students are required to submit a final written report. This term project model also encourages interdisciplinary collaboration with non-STEM disciplines, such as the Marketing course in USMA's Department of Behavioral Sciences and Leadership. This cross-cutting educational method can create more holistic solutions to the identified problems and enhance student learning. To date, assessment of students who participated in the real-world, client-based project versus a general environmental project indicated an improvement in several important areas: valuation of results, motivation and understanding, and confidence in problem solving skills. This work presents the methods our program developed to incorporate the scientific method, hypothesis development, and sampling methodologies to help solve these relevant real-world problems. The methods required to implement this educational experience in environmental engineering programs to meet ABET accreditation requirements are also discussed.

AB In-well-pumped blue InGaN/GaN vertical-external-cavity surface-emitting lasers are demonstrated. The laser structures were grown on bulk GaN substrates by using metal-organic vapor phase epitaxy near atmospheric pressure. The active zone consisted of up to 20 InGaN quantum wells distributed in a resonant periodic gain configuration. High-reflectivity dielectric distributed Bragg-reflectors were used as mirrors. Laser emission with a single longitudinal mode at 440 nm was achieved by exclusively pumping the quantum wells with the 384 nm emission line of a dye-/N2-laser.

High performance is achieved through highly parallel core algorithms, executed on multiple compute devices across a heterogeneous architecture using low-level OpenCL kernels. Algorithms for calculating line-of-sight ballistic threat, visual observability, ground plane extraction, and Markov chain Monte Carlo optimization provide an augmented geospatial intelligence and situational awareness in three-dimensional urban environments.

AB The estimation of temperature inside a battery cell requires accurate information about the cooling condition even when the battery surface temperature is measured. This paper presents a model-based approach for estimating the temperature distribution inside a cylindrical battery under the unknown convective cooling condition. A reduced order thermal model using a polynomial approximation of the temperature profile inside the battery is used. A Dual Extended Kalman Filter (DEKF) is then applied for the identification of the convection coefficient and the estimation of the battery core temperature. Experimental results show that the proposed DEKF-based estimation method can provide an accurate prediction of the core temperature under the unknown cooling condition by measuring the battery current and voltage along with surface and ambient temperatures.

AB In the real world, various systems can be modeled using heterogeneous networks which consist of entities of different types. People like to discover groups (or cliques) of entities linked to each other with rare and surprising associations from such networks. We define such anomalous cliques as Association-Based Clique Outliers (ABCOutliers) for heterogeneous information networks, and design effective approaches to detect them. The need to find such outlier cliques from networks can be formulated as a conjunctive select query consisting of a set of (type, predicate) pairs. Answering such conjunctive queries efficiently involves two main challenges: (1) computing all matching cliques which satisfy the query and (2) ranking such results based on the rarity and the interestingness of the associations among entities in the cliques. In this paper, we address these two challenges as follows. First, we introduce a new low-cost graph index to assist clique matching. Second, we define the outlierness of an association between two entities based on their attribute values and provide a methodology to efficiently compute such outliers given a conjunctive select query. Experimental results on several synthetic datasets and the Wikipedia dataset containing thousands of entities show the effectiveness of the proposed approach in computing interesting ABCOutliers.

AB In this paper we introduce the Organization, Relationship, and Contact Analyzer (ORCA) that is designed to aide intelligence analysis for law enforcement operations against violent street gangs. ORCA is designed to address several police analytical needs concerning street gangs using new techniques in social network analysis. Specifically, it can determine "degree of membership" for individuals who do not admit to membership in a street gang, quickly identify sets of influential individuals (under the tipping model), and identify criminal ecosystems by decomposing gangs into sub-groups. We describe this software and the design decisions considered in building an intelligence analysis tool created specifically for countering violent street gangs as well as provide results based on conducting analysis on real-world police data provided by a major American metropolitan police department who is partnering with us and currently deploying this system for real-world use.

AB Team science is a collaborative approach to research, typically with researchers drawn from different disciplines. Team science networks have certain unique characteristics in their conception and intent that set them apart from other commonly studied social and collaboration networks. We study the structural properties, and present metrics for collaborative performance assessment in two real-world team science networks initiated by the Army Research Lab. We model a team using a higher-order generalization of an edge called a simplex. A simplex captures group relationships distinct from the union of pairwise relationships. Our evaluation using a rigorous methodology reveals that the distributions of vertex and facet degrees (the number of maximal groups that a vertex belongs to) follow a power law, but with exponential cut-off at the tail in most cases. We propose metrics for quantitatively assessing the extent of intra-team and extra-team collaborations, and compare their effectiveness vis-a-vis our intuitive notions. Our work can be used as the basis for generative models, and for evaluating the collaborative performance of team science networks.

AB Because of exponential growth in smart mobile devices, malware attacks on smart mobile devices have been growing and pose serious threats to mobile device users. To address this issue, we develop a malware detection system, which uses a behavior-based detection approach to deal with the detection of a large number of unknown malware. To accurately detect malware, we examine system calls to capture the runtime behavior of software, which interacts with an operating system and adopt machine learning approaches such as Support Vector Machine (SVM) and Naive Bayes learning schemes to learn the dynamic behavior of software execution. Using real-world malware and benign samples, we conduct experiments on Android devices and evaluate the effectiveness of our developed system in terms of learning algorithms, the size of training set, the length of n-grams, and the overhead in training and detection processes. Our experimental data demonstrates the effectiveness of our proposed detection system to detect malware.

AB We investigate the problem of identifying individual link performance metrics in a communication network by measuring end-to-end metrics of selected paths between monitors, under the assumption that link metrics are additive and constant during the measurement, and measurement paths cannot contain cycles. In a previous work, we developed an algorithm that places the minimum number of monitors to identify all link metrics. However, even the minimum number can be large in some practical networks (e.g., 60% of all the nodes), suggesting high monitor deployment cost. In this paper, we study the dual problem where given a fixed number of monitors, we want to place them to maximize the number of identifiable link metrics, with concrete results for the case of two monitors. The significance of the two-monitor case is that all the tomographic computation can be performed at the destination monitor without shipping measurements to a central node, thus enabling endhost-based network monitoring. We develop an efficient algorithm to determine all identifiable links in an arbitrary network with a given placement of two monitors, based on which we propose an optimal two-monitor placement algorithm to maximize the number of identifiable links. Our evaluation on real ISP topologies shows that although a large number of monitors is needed to identify all link metrics, we can usually identify a substantial portion (up to 97%) of the links using a single pair of optimally placed monitors.

AB Multi-cell cooperation (MCC) mitigates intercell interference and improves throughput at the cell edge. This paper considers a cooperative downlink, whereby cell-edge mobiles are served by multiple cooperative base stations. The cooperating base stations transmit identical signals over paths with nonidentical path losses, and the receiving mobile performs diversity combining. The analysis in this paper is driven by a new expression for the conditional outage probability when signals arriving over different paths are combined in the presence of noise and interference, where the conditioning is with respect to the network topology and shadowing. The channel model accounts for path loss, shadowing, and Nakagami fading, and the Nakagami fading parameters do not need to be identical for all paths. To study performance over a wide class of network topologies, a random spatial model is adopted, and performance is found by statistically characterizing the rates provided on the downlinks. To model realistic networks, the model requires a minimum separation among base stations. Having adopted a realistic model and an accurate analysis, the paper proceeds to determine performance under several resource-allocation policies and provides insight regarding how the cell edge should be defined.

AB We consider the problem of collaborative target localization by several observers, called players, where the reliability of each player is unknown. As in our previous work [1] we formulate this problem as a 20 questions game with noise for collaborative players under a minimum entropy criterion. We extend the setting of [1] to the case where the players' error channels have unknown crossover probabilities. First, we use dynamic programming to characterize the structure of the optimal policy for constructing the sequence of questions. This generalizes the multiplayer policies derived in [1] for the known error channel setting. Second, we prove a separation theorem showing that a sequential bisection scheme achieves the same performance as the optimal joint queries. This generalizes the separation theorem recently derived for the known error channel case in [1]. Third, we derive bounds for the maximum entropy loss per iteration. Finally, we show that even for the one-dimensional case, the optimal query policy for the unknown error channel is not equivalent to a probabilistic bisection policy. This framework provides a methodology for simultaneous sequential estimation of target location and learning the error channels associated with the players.

AB We consider the problem of quickest localization of anomaly in a resource-constrained cyber network consisting of multiple components. Due to resource constraints, only one component can be probed at each time. The observations are random realizations drawn from two different distributions depending on whether the component is normal or anomalous. Components are assigned priorities. Components with higher priorities in an abnormal state should be fixed before components with lower priorities to reduce the overall damage to the network. The objective is to minimize the expected weighted sum of completion times of abnormal components subject to error probability constraints. We consider two different anomaly models: the independent model in which each component can be abnormal independent of other components, and the exclusive model in which there is one and only one abnormal component. We develop index policies under both models. Optimal low-complexity algorithms are derived for the simple hypotheses case, where the distribution is completely known under both hypotheses. Asymptotically (as the error probability approaches zero) optimal low-complexity algorithms are derived for the composite hypotheses case, where there is uncertainty in the distribution parameters. Simulation results then illustrate the performance of the algorithms.

DE Hole Localization; Simplicial Complex; Simplicial Collapse; Sensor
Network Coverage; Homology
AB Algebraic topology has been successfully applied to detect and localize sensor network coverage holes with minimal assumptions on sensor locations. These methods all use a computation of topological invariants called homology spaces. We develop a distributed algorithm for collapsing a sensor network, hence simplifying its analysis. We prove that the collapse is equivalent to a previously developed strong collapse in that it preserves coverage hole locations. In this way, the collapse simplifies the network without losing crucial information about the coverage region. We show that the algorithm requires only one-hop information in a communication network, making it faster than clique-finding algorithms that increase the number of computations necessary for hole localization. This makes it an effective pre-processing step to finding network coverage holes.

AB Recently, new techniques for passive imaging based on distributed aperture imagers have been developed. One promising approach utilizes photonic sampling, routing, and processing of the millimeter-wave energy for image generation. Many signal processing aspects of this approach that have been explored to date, from engineering phase profiles across the array to achieve dynamically adjustable point spread functions, to noise reduction techniques in the optical image regeneration. Herein, we focus on a method to reduce image bias in a distributed aperture millimeter wave imager by switching the phase in individual channels by pi-phase. Our simulations indicate this approach has better bias performance than random phase switching.

AB We present a minimalist model for estimating point-to- point wireless connectivity in robotic networks where every node in the network is mobile, i.e., the space of the problem is truly R-2 x R-2. This model is built on the idea that the geometry of an environment leads to a region-based decomposition where communication between pairs of regions can be approximated accurately by simple stochastic models. We develop an estimation framework that allows for these simple stochastic models to be predicted and updated based on sparse measurements as demonstrated experimentally.

AB A new analysis is presented for the direct-sequence code-division multiple access (DS-CDMA) cellular uplink. For a given network topology, closed-form expressions are found for the outage probability and rate of each uplink in the presence of path-dependent Nakagami fading and log-normal shadowing. The topology may be arbitrary or modeled by a random spatial distribution for a fixed number of base stations and mobiles placed over a finite area with the separations among them constrained to exceed a minimum distance. The analysis is more detailed and accurate than existing ones and facilitates the resolution of network design issues, including the influence of the minimum base-station separation, the role of the spreading factor, and the impact of various power-control and rate-control policies. It is shown that once power control is established, the rate can be allocated according to a fixed-rate or variable-rate policy with the objective of either meeting an outage constraint or maximizing throughput. An advantage of the variable-rate policy is that it allows an outage constraint to be enforced on every uplink, whereas the fixed-rate policy can only meet an average outage constraint.

AB This paper considers ad hoc networks that use the combination of coded continuous-phase frequency-shift keying (CPFSK) and frequency-hopping multiple access. Although CPFSK has a compact spectrum, some of the signal power inevitably splatters into adjacent frequency channels, thereby causing adjacent-channel interference (ACI). The amount of ACI is controlled by setting the fractional in-band power; i.e., the fraction of the signal power that lies within the band of each frequency channel. While this quantity is often selected arbitrarily, a tradeoff is involved in the choice. This paper presents a new analysis of frequency-hopping ad hoc networks that carefully incorporates the effect of ACI. The analysis accounts for the shadowing, Nakagami fading, CPFSK modulation index, code rate, number of frequency channels, fractional in-band power, and spatial distribution of the interfering mobiles. Expressions are presented for both outage probability and transmission capacity. With the objective of maximizing the transmission capacity, the optimal fractional in-band power that should be contained in each frequency channel is identified.
