The most significant advantages of the CQD technology are ease of fabrication, small pixel size, and extended wavelength range. The devices are fabricated directly onto the ROIC substrate at low temperatures compatible with CMOS, and arrays can be fabricated at wafer scale. We will discuss recent advances in device architecture and processing that result in measured dark currents of 15 nA/cm(2) at room temperature and enhanced SWIR responsivity 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.

However, its development has been hindered by many problems in relation to the out-diffusion of dissolved lithium polysulphide (PS, Li2Sn with 4 <= n <= 8), the series of sulphur reduction intermediates. In this paper we demonstrate a proof of concept for blocking the out-diffusion of the dissolved PS by employing a dual-layer structural sulphur cathode with a porous poly(acrylic acid) (PAA) membrane coated on the top surface. Upon activation with the liquid electrolyte, the porous PAA membrane becomes a gel and the resulting gel chemically blocks the out-diffusion of PS anions by forming hydrogen bonds between the COOH groups in the gelled PAA and the negatively charged PS anions. Verified visually by a potentiostatic polarization experiment at 1.7 V vs. Li/Li+, the out-diffusion of PS in an electrolyte-flooded Li/S cell is effectively blocked by the dual-layer structural sulphur cathode. As a result, the Li/S cell consisting of a dual-layer structural sulphur cathode exhibits much improved capacity retention while still providing a similar specific capacity, as compared with the cell using the conventional sulphur cathode.

However as the communication range increases, the communication performance deteriotes due to NLOS UV turbulence, even with special UV turbulence mitigation. In this work, we conducted a series of outdoor experiments to investigate the received signal energy distribution, which is the product of the complex interaction of transmitted UV radiation, by utlizing both a UV LED array and a UV laser, with the atmosphere. Separation distance, pointing angles and UV light source were taken into considerate as key parameters to affect the distribution. These experimental results will be valuable for studying NLOS UV communication performance.

The nanoparticles were pressed into ceramic discs that exhibited optical transmission approaching the theoretical limit and showed very high optical-to-optical lasing slope efficiency. We have also synthesized sesquioxide nanoparticles using a Flame Spray Pyrolysis (FSP) technique that leads to the synthesis of a metastable phase of sesquioxide which allows fabricating excellent optical quality transparent windows with very fine grain sizes. Finally, we present our research in the synthesis of rare earth doped boehmite nanoparticles where the rare-earth ion is encased in a cage of aluminum and oxygen to prevent ion-ion proximity and energy transfer. The preforms have been drawn into fibers exhibiting long lifetimes and high laser efficiencies. C1 [Baker, C.; Kim, W.; Friebele, E. J.; Villalobos, G.; Frantz, J.; Shaw, L.

Nano-structured thermoelectric materials are predicted to offer higher ZT over bulk materials by reducing thermal conductivity and increasing electrical conductivity. Consolidation of nano-structured powders into dense materials without losing nanostructure is essential towards practical device development. Using the gas atomization process, amorphous nano-structured powders were produced. Shockwave consolidation is accomplished by surrounding the nanopowder-containing tube with explosives and then detonating. The resulting shock wave causes rapid fusing of the powders without the melt and subsequent grain growth. We have been successful in generating consolidated nanostructured bismuth telluride alloy powders by using the shockwave technique. Using these consolidated materials, several types of thermoelectric power generating devices have been developed. Shockwave consolidation is anticipated to generate large quantities of nanostructred materials expeditiously and cost effectively. In this paper, the technique of shockwave consolidation will be presented followed by Seebeck Coefficient and thermal conductivity measurements of consolidated materials. Preliminary results indicate a substantial increase in electrical conductivity due to shockwave consolidation technique.

Hits bearing an electron-rich aromatic residue across strand from a reactive histidine were found to competitively become N-acylated. In addition to displaying rapid N-acylation rates the hit peptide was additionally deacylated in the presence of a nucleophile, thus closing a putative catalytic cycle. Variants of the hit peptide were studied to elucidate both the magnitude (up to 18 000-fold over background, k(cat)/k(uncat) = 94 000 000, or 45-fold over Boc-histidine methyl ester) and mechanism of acyl transfer catalysis. A combination of CH-pi, cation-pi and HisH(+)-O interactions in the cationic imidazole transition state is implicated in the rate acceleration, in addition to the fidelity of the beta hairpin fold. Moreover, NMR structural data on key intermediates or models thereof suggest that a key feature of this catalyst is the ability to access several different stabilizing conformations along the catalysis reaction coordinate.

Our in-house developed adaptive optics (AO) system, which contains high-performance deformable mirrors (DMs) and the fast stochastic parallel gradient decent (SPGD) control mechanism, allows effective compensation of such turbulence-induced wavefront aberrations and result in significant improvement on the image quality. In addition, we developed advanced digital synthetic imaging and processing technique, "lucky-region" fusion (LRF), to mitigate the image degradation over large field-of-view (FOV). The LRF algorithm extracts sharp regions from each image obtained from a series of short exposure frames and fuses them into a final improved image. We further implemented such algorithm into a VIRTEX-7 field programmable gate array (FPGA) and achieved real-time video processing. Experiments were performed by combining both AO and hardware implemented LRF processing technique over a near-horizontal 2.3km atmospheric propagation path. Our approach can also generate a universal real-time imaging and processing system with a general camera link input, a user controller interface, and a DVI video output.

Nevertheless, improvements to existing battery technology are necessary to expand their utility for larger-scale applications, such as electric vehicles. Advances may be realized from improvements to the liquid electrolyte; however, current understanding of the liquid structure and properties remains incomplete. X-ray absorption spectroscopy of solutions of LiBF4 in propylene carbonate (PC), interpreted using first-principles electronic structure calculations within the eXcited electron and Core Hole (XCH) approximation, yields new insight into the solvation structure of the Li+ ion in this model electrolyte. By generating linear combinations of the computed spectra of Li+- associating and free PC molecules and comparing to the experimental spectrum, we find a Li+ -solvent interaction number of 4.5. This result suggests that computational models of lithium ion battery electrolytes should move beyond tetrahedral coordination structures.

Channels influence ebb shoal formation and sediment bypassing, which includes attachment bars where the shoal abuts the shoreline. Interruption or modification of sediment bypassing mechanisms at coastal inlets alters sediment supply to adjacent beaches, frequently resulting in shoreline erosion. Historically, structures and/or periodic beach fill have been implemented on impacted shorelines. The US Army Corps of Engineers maintains an entrance channel on the Savannah River near Tybee Island, GA, USA. This deep-draught navigation channel has influenced sediment bypassing by the ebb shoal and appears to have contributed to shoreline recession on the north part of Tybee Island. The Corps has addressed this recession issue by beach-placement of sand from an offshore borrow site. The Corps also dredges a significant amount of material from the entrance channel each year to maintain navigability. This dredged material is often greater than 70% sand. However, it is not considered suitable for beach placement. The Corps is investigating nearshore placement of this dredged material along Tybee Island. The goal of nearshore placement is to indirectly nourish the beach by increasing sand supply in the littoral zone. The proposed method of using dredged material will potentially provide a lower-cost alternative to expensive sand-mining and direct beach placement. Nearshore placement of this non-beach quality material will permit natural surf-zone processes to winnow the unwanted fine-grained material and transport it offshore. The Corps initiated a study to investigate the feasibility of nearshore placement for beneficial use of dredged material to nourish the littoral zone. This paper describes a portion of the issues and study methods. Specifically, hydrodynamic, wave and sediment transport models were utilised to assess the fate of dredged material placed in the nearshore. Optimal placement sites were selected based on the study findings. C1 [Gailani, Joseph Zane; Smith, Stanley Jarrell] US Army Corps Engineers, Engineer Res & Dev Ctr, Vicksburg, MS USA.

Chris BE Harmon, RS Baker, SE McDonald, EV TI Environmental security revived: A global security threat SO MILITARY GEOSCIENCES IN THE TWENTY-FIRST CENTURY SE Reviews in Engineering Geology LA English DT Article; Book Chapter AB National defense is viewed by many as a uniquely military activity to fight and win our nation's wars. The world that we live in today causes us to rethink this idea as the realities of today's defense missions take shape. The wars in Iraq and Afghanistan are part of what is reshaping our image of national defense, but also emerging is the recognition that large-scale environmental degradation manifests security threats that can be global in scope. This paper examines this issue in the context of environmental security analysis. Although, the security implication of climate change is the issue that has brought new focus to this concept, this one environmental calamity is not the only environmental security challenge we will face in the future. The paper outlines an approach to analyzing environmental security threats on a regional and world scale. It is a fusion of science, political science, and strategic defense analysis.

We focus here on when, where, and why military installations, primarily those of the Army, were created and placed on the landscape, and we examine some of the ways in which their situation changed as the country shifted from a domestic protection stance to a more internationalist projection-oriented operational philosophy. The 1790s, the 1890s, and the 1990s each presented challenges-but of very different types. Were we responding to external or internal threats? What were the needs of the era? Were they focused on materiel production, on leadership and training, on protecting our coastlines, on protecting travel routes within the country, or on preparing to project force hundreds or thousands of miles outside the United States? At one time, one or more of these differing concerns were the driving reasons behind the establishment of a military installation. The current "landscape" of installations reflects a response to these differing threats across our entire nation's history. This is why the U.S. Defense Department has recently been reviewing the inventory of military bases, to determine if they are all still relevant and useful. Do we now have too many or too few installations? Or, are they in the wrong place to answer the current and emerging threats? Finally, what happens when an installation is believed to no longer be needed? When and how may an installation be converted to another life?

Fundamental geographic factors such as radiation balance, wind and dust, and unique terrain have affected the outcome of desert campaigns and battles throughout history. While the scientific community understands desert geography, the fundamental effects of environmental factors on military operations are rarely well known or understood. Some level of understanding is necessary to provide context for researchers solving military problems. The purpose of this paper is to offer a military context for the work in this volume. This study provides a brief summary of the influences selected environmental factors may have on modern military forces operating in hot desert environments. In particular, this research examines the effects of unique desert terrain, aeolian processes and dust, and radiation balance with regard to troops, equipment, and tactics; historical and modern examples illustrate these effects.

BE Harmon, RS Baker, SE McDonald, EV TI Dust storms and the 1980 Iran hostage rescue attempt SO MILITARY GEOSCIENCES IN THE TWENTY-FIRST CENTURY SE Reviews in Engineering Geology LA English DT Article; Book Chapter AB Dust storms, or haboobs, can have a significant effect on military operations in arid regions. Not only does dust cause maintenance problems and slow offensive ground operations, but it can also substantially disrupt air operations. This paper presents a historic vignette of how a dust storm contributed to the failure of Operation Eagle Claw, the mission undertaken to rescue U.S. hostages in Iran in 1980. The flight crews that were involved in that mission encountered a dust storm that was likely generated by thunderstorm activity in the Zagros Mountains of Iran. Weather forecasters were aware that dust storms were a possibility in the region, but they did not forecast haboobs. The pilots were expecting clear weather and had no contingency plans to cope with the adverse weather conditions. The dust storm caused confusion, slowed the helicopters, and greatly increased pilot fatigue. These factors appeared to have contributed to mission failure, and, as a result, the U.S. military later implemented many improvements in mission planning, pilot training, and weather forecasting techniques to manage the risk associated with operations in areas where dust storms are likely.

It is imperative that military equipment is designed and tested for use in this environment; that soldiers are trained to operate in the desert; and that they can accomplish their missions under the extreme conditions presented by this distinct operating environment. Understanding desert processes and terrain is fundamental to accomplishing these goals. Scientists have long debated demarcation and classification of deserts, considering many measurable factors. However, few have classified deserts in a way that specifically supports the military missions of operating, training, and testing. This research was undertaken to classify deserts using both physical and military variables and to develop a system that examines deserts from a military perspective. A panel of scientists and military officers developed and tested a model of warm and hot desert classification. The robustness of the model was tested at the Yuma Proving Ground, Arizona, and the National Training Center at Fort Irwin, California. This work is a preliminary step toward a thorough examination of desert training and testing sites and potential conflict areas in desert locations throughout the world.

Airborne dust is commonly generated in the desert by surface and near-surface operations during operational, testing, and training missions. Currently, there is no standardized procedure for testing dust suppressants, and the U.S. military lacks a specific test operations procedure (TOP) designed to provide realistic testing of the performance and durability of commercial products sold for dust abatement. The primary purpose of this study is to provide recommendations for the future development of a TOP for testing dust suppressants applied to desert soils. Recommendations were developed from the evaluation of a polyvinyl-based synthetic polymer as a dust suppressant, which was tested at four test intervals over a 19-week period in the late spring and summer of 2008 at the U.S. Army Yuma Proving Ground. The dust suppressant was applied at three separate test sites having different surface characteristics and soil properties ranging from loose, sandy gravel to gravelly sand, alluvial-fan soils to soft, sandy-silt, alluvial-plain soils. Each test site was subjected to a variety of traffic impact types consisting of an increasing number of cumulative passes by different vehicle types-including a low-flying helicopter, a light-weight armored tracked vehicle, and heavy-, medium-, and lightweight wheeled vehicles, plus pedestrian foot traffic. In addition to the sites of traffic impact, three types of control plots were concurrently tested to act as reference sites, as well as to evaluate the longevity of the suppressant, which included: disturbed and static (undisturbed) baseline plots and a static benchline plot. Surface soil and dust-suppressant physical properties were measured following each traffic impact in the form of shear strength and bearing capacity, plus dust-emission flux as measured by a Portable In Situ Wind ERosion Laboratory (PI-SWERL). Results from this study show that dust-emission flux and surface-strength measurements from a layout of control and traffic impact test plots provide a quantifiable and repeatable approach in measuring the efficacy of a dust suppressant for a TOP used by the U.S. Army.

The relative value of military lands as bioreserves compared to land holdings of other federal agencies is not proportional to total land area. Ironically, a significant reason that U.S. military installations have become important bioreserves is that they were not established with the purpose of conserving or extracting natural resources. This historical factor has resulted in a broad representation of U.S. ecoregions on military lands and largely has shielded those lands from the habitat loss and degradation that has occurred in surrounding regions due to urbanization, agricultural development, and other non-military land uses. Fort Hood, Texas, is used as a case study to illustrate the characteristics of military installations that fit the model for bioreserves as areas for conservation of biological resources and processes in the context of human use of the environment. A major current challenge for management of natural resources on military lands is that the value of U.S. military lands as bioreserves is increasing as surrounding habitats and natural communities continue to be degraded.

BE Harmon, RS Baker, SE McDonald, EV TI Overview of Department of Defense land use in the desert southwest, including major natural resource management challenges SO MILITARY GEOSCIENCES IN THE TWENTY-FIRST CENTURY SE Reviews in Engineering Geology LA English DT Article; Book Chapter ID MOJAVE DESERT AB Department of Defense military land use of the desert southwest includes a wide spectrum of military weapons testing, force-on-force training, and various types of flight training. The desert southwest provides a critical asset for the U.S. military-open space. Installations in the desert southwest tend to be much larger than installations in other regions of the nation, with several exceeding 400,000 ha. This open-space asset has allowed the military to historically establish large training areas and ranges on installations and to define expansive air maneuver regions above these ranges and above the vast public lands of other agencies. It also offers critical training and testing areas that are analogs to similar worldwide environments where the military operates. Training and testing activities are conducted in the three-dimensional land and air space that replicates the modern battle space. Land and air space use is highly variable among installations depending on mission requirements. Natural resource management challenges include the large spatial extent of lands and air space under Department of Defense management, highly variable military land-use requirements, significant endangered species regulatory and conservation requirements, encroachment and Base Realignment and Closure requirements, competition for water resources, and climate change. Department of Defense natural resource managers attempt to meet these challenges through interagency cooperative agreements, integrated natural resource management plans, and Department of Defense sustainable range programs.

In addition, feedbacks among (1) nearshore bathymetry, (2) waves and nearshore circulation, and (3) underlying geology directly affect the morphology of the adjacent beach as well as the shoreline's response to storm events, resulting in localized erosional "hotspots." These hotspots are potentially hazardous for equipment and personnel staging along the beach, but they are not easily identifiable from a time-series of aerial photographs alone. We identify several environmental metrics necessary for the reliable prediction of potential coastal landing and staging hazards, including: (1) nearshore bathymetric gradients, (2) nearshore sediment volume, and (3) changes in shoreline and vegetation line position. Coupled with a quantitative understanding of the relevant coastal processes, these data allow an assessment of potential nearshore bathymetric hazards and realistic predictions of short-term shoreline stability and thus suitability for the temporary staging of equipment and personnel. These metrics are applied to Onslow Beach, North Carolina, Marine Corps Base Camp Lejeune, the largest amphibious training ground in the United States, and they are used to identify potential amphibious transit and staging hazards along the entire coastal zone, from the beach out to similar to 11 m water depth.

However, thermal-to-visible face recognition is a highly challenging problem, due to the large modality gap between thermal and visible imaging. In this paper, we propose a thermal-to-visible face recognition approach based on multiple kernel learning (MKL) with support vector machines (SVMs). We first subdivide the face into non-overlapping spatial regions or blocks using a method based on coalitional game theory. For comparison purposes, we also investigate uniform spatial subdivisions. Following this subdivision, histogram of oriented gradients (HOG) features are extracted from each block and utilized to compute a kernel for each region. We apply sparse multiple kernel learning (SMKL), which is a MKL-based approach that learns a set of sparse kernel weights, as well as the decision function of a one-vs-all SVM classifier for each of the subjects in the gallery. We also apply equal kernel weights (non-sparse) and obtain one-vs-all SVM models for the same subjects in the gallery. Only visible images of each subject are used for MKL training, while thermal images are used as probe images during testing. With subdivision generated by game theory, we achieved Rank-1 identification rate of 50.7% for SMKL and 93.6% for equal kernel weighting using a multimodal dataset of 65 subjects. With uniform subdivisions, we achieved a Rank-1 identification rate of 88.3% for SMKL, but 92.7% for equal kernel weighting.

Thus, the validity of the doctrine of defensive jihad is inherently linked to its universal application to all Muslims. Jihadi ideologues and leaders, however, have either purposely refrained from calling on women to make their presence felt on the battlefield as warriors or have explicitly excluded them. This article is an investigation into this lacuna in jihadi ideology. It addresses a dimension that is hardly, if ever, discussed in the academic literature, namely the jihadis' exclusion of women from combat. This exclusion represents a gaping hole in jihadi ideology and undermines the validity of the jihadis' defensive jihad.

These threats include explosives in the form of improvised explosive devices (IEDs) as well as low volatility chemical agents and toxic industrial chemicals (TICs). The ability to assess surface hazards, even at standoff distances as short as 1 m, would provide an increased level of safety to those tasked with assessing sites with possible weapons of mass destruction (WMD). A number of optical spectroscopy techniques have been investigated to solve this problem. Laser-induced breakdown spectroscopy (LIBS), fluorescence, and Raman all show promise for meeting this challenge of surface detection, with each having both advantages and disadvantages. While most of the work to date has been on assessing these techniques individually, more emphasis is being placed on combining orthogonal detection techniques for improved probability of detection and the reduction in false positives.

The chapter begins with a brief discussion of the basic theory of each of the three techniques: laser-induced fluorescence spectroscopy (LIF), Raman spectroscopy, and laser-induced breakdown spectroscopy (LIBS). Once the basic theory has been introduced, the remainder of the chapter focuses on review of the current research, and applications of these techniques for the analysis of various types of forensic evidence. The forensic topics that are the focus of this chapter are explosives, glass, paint, inks, bodily fluids, and fibers. C1 [Rinke-Kneapler, C.

Translation, rotation and reflection of the potential, q(0) induce transformations of the scattered wave. The latter can be represented by means of Born sequences, where q(0) appears under the integral sign: non-local formulas are thus derived, the properties of which are discussed. Next, the symmetries induced by the 1st Born approximation are addressed. Invariance of the squared modulus of the scattering amplitude holds for translation and reflection. The transformation T-is an element of:= 1(3) + Sigma(3)(l=1) epsilon(l)A(l), with {epsilon(l)} real and {A(l)} the generators of rotations in IR3, is investigated. Conditions on the {epsilon(l)} are derived, by which the scattering amplitude coming from the first Born approximation is invariant to T-epsilon. As an application, these "false symmetries" are compared to those induced by limited angular resolution of a detector in light scattering experiments. Namely, scattering patterns are made available by the TAOS (Two-dimensional Angle-resolved Optical Scattering) method, which consists of detecting single airborne aerosol particles and collecting the intensity of the light they scatter from a pulsed, monochromatic laser beam. The optics and the detector properties determine the resolution at which a pattern is saved. The implications on the performance of TAOS pattern analysis are briefly discussed.

Many recent studies attempt to relate turbulence characteristics to habitat utilization, but results are inconsistent for two reasons. First, turbulence is a complex, multi-scale manifestation of fluid flow that can be characterized in different ways with different interpretations. Second, fish behavioral response to flow field features is also complex because both acclimation and learning are important. For example, some studies show that turbulence decreases swimming stability, increases energy expenditure for a given swimming speed, and alters feeding behavior, whereas others show turbulence to decrease energy needed to swim at a given speed and correlates with fish abundance. We describe a Turbulence Attraction and Avoidance (TAA) hypothesis to reconcile inconsistent, even seemingly contradictory, findings. The TAA hypothesis creates a new perspective of turbulence, habitat complexity, and fish habitat occupancy by acknowledging that fish, like all animals, perceive their environment at their own relevant scales and in a conditional manner, dependent on their prior exposure history.

Although this research has primarily focused on short-range applications, the achievable range of a NLOS UV system can be extended (e. g., up to a few kilometers) with the use of a pulsed UV laser transmitter. However, the short-duration high-intensity pulses of such a laser have the potential to overwhelm the response time of photomultiplier detectors, which are often employed by a receiver to implement high-sensitivity photon-counting detection. In particular, after the detection of a photon, there exists a period of time, called dead time, during which the detector is unable to detect subsequently impinging photons, resulting in missed photon detections and, hence, altered received signal statistics relative to an ideal photon counter. In this paper, we examine the effect of receiver dead time on a NLOS UV system. We extend an existing UV NLOS channel model to account for nonzero dead time at the receiver and then use this extended model to examine the significance of dead-time effects for various representative system configurations. The results suggest the importance of accounting for dead time when designing practical UV communication systems.

Emphases are also put on data quality, qualitative validation of expected atmospheric spectral features, and qualitative comparison against another dataset of the same site using a different LWIR hyperspectral sensor. SPICE is a collaborative effort between the Army Research Laboratory, U.S. Army Armament RDEC, and more recently the Air Force Institute of Technology. It focuses on the collection and exploitation of longwave and midwave infrared (LWIR and MWIR) hyperspectral and polarimetric imagery. We concluded from this work that the quality of SPICE hyperspectral LWIR data is categorically comparable to other datasets recorded by a different sensor of similar specs; and adequate for algorithm research, given the scope of SPICE. The scope was to conduct a long-term infrared data collection of the same site with targets, using both sensing modalities, under various weather and non-ideal conditions. Then use the vast dataset and associated ground truth information to assess performance of the state of the art algorithms, while determining performance degradation sources. The expectation is that results from these assessments will spur new algorithmic ideas with the potential to augment pattern recognition performance in remote sensing applications. Over time, we are confident the SPICE database will prove to be an asset to the wide open remote sensing community. C1 [Rosario, Dalton] Army Res Lab, 2800 Powder Mill Rd, Adelphi, MD 20783 USA.

Tritium is a biologically benign beta emitter and low-cost isotope acquired from commercial vendors for this purpose. The power source combines tritium encapsulated with a radioluminescent phosphor coupled to a commercial PV cell. The tritium, phosphor, and PV components are packaged inside a BA5590-style military-model enclosure. The package has been approved by the nuclear regulatory commission (NRC) for use by DOD. The power source is designed to produce 100 mu W electrical power for an unattended radiation sensor (scintillator and avalanche photodiode) that can detect a 20 mu Ci source of Cs-137 at three meters. This beta emitting indirect photon conversion design is presented as step towards the development of practical, logistically acceptable, low-cost long-lived compact power sources for unattended sensor applications in battlefield awareness and environmental detection.

However, research about which factors (trait and state) affect how real a simulation is to a person and how this "realness" affects cognition is lacking. Presence research lacks the assessment of interactions between psychological and physiological responses in interactive immersive environments. This paper provides empirical results from both trait and state psychological and physiological measures to identify and provide operationally relevant information regarding the realism of presence in a 300 degrees immersive simulation and its effects on a Shoot-Don't-Shoot decision-making task. Participants engaged in a Shoot-Don't-Shoot simulation under three types of feedback conditions: (1) small shock, (2) life bar, and (3) no feedback. Results indicate that (1) trait uncertainty mitigates the stress experience and (2) both immersion and errors were significantly greater in the shock condition. Recommendations for future research are discussed. C1 US Army, Ballist Res Lab, Aberdeen Proving Ground, MD 21005 USA.

Elements of self-regulatory learning traditionally include the metacognitive strategies of the students (e. g., their knowledge of their planning, and assessment of their own progress), their management of educational goals (e. g., what information is most important to them, and should receive their primary attention), and the strategies that students use in order to study and retain the provided information [1, 2]. By incorporating feedback and guidance within computer-based learning activities it can encourage students to engage in successful self-regulated learning with a better awareness of their own cognition, and strategies. Intelligent tutoring systems can utilize adaptive scaffolding and guidance in order to support self-regulated student learning [3]. The Generalized Intelligent Framework for Tutoring (GIFT) [4] is an open-source adaptive tutoring system framework. The included tools within GIFT can be used to structure courses which guide individuals through the learning environment and are consistent with self-regulated best practices. The current paper includes a brief review of research into self-regulated learning in the context of computer-based and adaptive instruction. Further, the authoring capabilities of GIFT are discussed, and recommendations are given for future feature additions to GIFT which will benefit instructors who wish to develop courses that facilitate self-regulated learning.

Analysis of open source information provides valuable insights into determining opinions, values, cultural nuances and other socio-political aspects within a military area of interest.

For example, SM could provide ongoing assessment of disaster relief and humanitarian operations from a local perspective, or offer an understanding of risk levels to which the operators in question are exposed. Despite its potential value, there are significant technological barriers to leveraging SM. SM collection and analysis are difficult in the dynamic SM environment and deception is a real concern. This paper introduces a credibility analysis approach and prototype fact-finding technology called the "Apollo Fact-finder" that mitigates the problem of inaccurate or falsified SM data. Apollo groups data into sets (or claims), corroborating specific observations, then iteratively assesses both claim and source credibility resulting in a ranking of claims by likelihood of occurrence. These credibility analysis approaches are discussed in the context of a hypothetical humanitarian mission executed in an area of active conflict and applied to public domain tweets collected in the aftermath of a Syrian crisis.

Motivated by use cases in the domain of Company Intelligence Support Team (CoIST) tasks, this paper presents an approach to information collection, fusion and sense-making based on the use of natural language (NL) and controlled natural language (CNL) to support richer forms of human-machine interaction. The approach uses a conversational protocol to facilitate a flow of collaborative messages from NL to CNL and back again in support of interactions such as: turning eyewitness reports from human observers into actionable information (from both soldier and civilian sources); fusing information from humans and physical sensors (with associated quality metadata); and assisting human analysts to make the best use of available sensing assets in an area of interest (governed by management and security policies). CNL is used as a common formal knowledge representation for both machine and human agents to support reasoning, semantic information fusion and generation of rationale for inferences, in ways that remain transparent to human users. Examples are provided of various alternative styles for user feedback, including NL, CNL and graphical feedback. A pilot experiment with human subjects shows that a prototype conversational agent is able to gather usable CNL information from untrained human subjects.

Fiber-based transmission of quantum information over long distances may be achieved using quantum memory elements and quantum repeater protocols. However, atom-based quantum memories typically involve interactions with light fields outside the telecom window needed to minimize absorption in transmission by optical fibers. We report on progress towards a quantum memory based on the generation of 795 nm spontaneously emitted single photons by a write-laser beam interacting with a cold Rb-87 ensemble. The single photons are then frequency-converted into (out of) the telecomm band via difference (sum) frequency generation in a PPLN crystal. Finally, the atomic state is read out via the interaction of a read-pulse with the quantum memory. With such a system, it will be possible to realize a long-lived quantum memory that will allow transmission of quantum information over many kilometers with high fidelity, essential for a scalable, long-distance quantum network.

The future of PTSD treatment may specifically target the molecular mechanisms of PTSD. In the US, approximately 20% of adults report taking herbal products to treat medical illnesses. L-theanine is the amino acid in green tea primarily responsible for relaxation effects. No studies have evaluated the potential therapeutic properties of herbal medications on gene expression in PTSD. We evaluated gene expression in PTSD-induced changes in the amygdala and hippocampus of Sprague-Dawley rats. The rats were assigned to PTSD-stressed and nonstressed groups that received either saline, midazolam, L-theanine, or L-theanine + midazolam. Amygdala and hippocampus tissue samples were analyzed for changes in gene expression. One-way ANOVA was used to detect significant difference between groups in the amygdala and hippocampus. Of 88 genes examined, 17 had a large effect size greater than 0.138. Of these, 3 genes in the hippocampus and 5 genes in the amygdala were considered significant (P < 0.05) between the groups. RT-PCR analysis revealed significant changes between groups in several genes implicated in a variety of disorders ranging from PTSD, anxiety, mood disorders, and substance dependence.

Often the reconstruction problem is ill-posed resulting in unrealistic reconstructions of signals and images. This paper examines the consequences of using extremal entropy metrics in the reconstruction. These range from inducing sparsity to the closer conformance of the reconstruction boundaries to the support of the actual signal source.

The incidences of overuse injuries and attrition of 85 male and 235 female recruits in a light infantry brigade was followed in a three-year prospective study. Females were shorter (162 cm, CI 161-163 cm) than males (174 cm, CI 173-176), had more body fat (18.9 kg, CI 18.2-19.6 kg) than males (12.6 kg, 11.3-13.8 kg), had lower VO2 max (36.8 mL.min(-1).kg(-1), CI 35.8-37.78 mL.min(-1).kg(-1)) than males (50.48 mL.min(-1).kg(-1), CI 48.4 to 52.48 mL.min(-1).kg(-1)), had more stress fractures (21.0%, 95% CI 16.2-26.5%) than males (2.3%, CI 0.3-8.2%), and had more anterior knee pain (41.2%, CI 34.9-47.7%) than males (24.7%, CI 16.0-35.2%). Three-year attrition was 28% CI 22-34% for females and 37% CI 26-48% for males. The females in this study successfully served as light infantry soldiers. Their lower fitness and high incidence of overuse injuries might impede service as regular infantry soldiers.

To examine plant communities along spring watercourse- upland gradients, we sampled 12 springs at low (desert) and high (forest) elevations on the Desert National Wildlife Refuge in the Mojave and Great Basin Deserts in southern Nevada. In contrast to the commonly reported positive relationship between native and exotic species richness in sampling studies, we did not find strong correlations (r(2) < 0.05) between native and exotic richness at any distance from watercourses. Additionally, exotic species cover was lower nearest (0 and 2 m) watercourses than at uplands 20 m from watercourses, which also differs from the hypothesis that watercourses are more heavily invaded than uplands. Exotic species were more pervasive at low-elevation compared to high-elevation springs, but the proportion of total plant cover comprised by exotics was still small (0.03 - 0.06) at low-elevation springs. Species distributions and ordinations suggested that compositional watercourse- upland gradients were often readily detectable, but the composition of springs was individualistic. Some springs contained wetland species such as Juncus saximontanus, while other springs contained species of dry-site affinity. This study also illustrated challenges associated with estimating reference conditions for arid-land springs, as there are no known data prior to the development (i.e., modifying surface flow) of the springs and no known unmodified springs on this landscape.

The WA uses a doctrinally-based knowledge representation to model role-specific workflows and continuously monitors the state of the operational environment to enable decision-support, delivering the right information to the right person at the right time. Capabilities include: (1) analyzing combat events reported in chat rooms and other sources for relevance based on role, order-of-battle, time, and geographic location, (2) combining seemingly disparate pieces of data into meaningful information, (3) driving displays to provide users with map based and textual descriptions of the current tactical situation, and (4) recommending courses of action with respect to necessary staff collaborations, execution of battle-drills, re-tasking of ISR assets, and required reporting. The results of a scenario-based human-in-the-loop experiment are reported. The underlying WA knowledge-graph representation serves as state traces, measuring aspects of Soldier decision-making performance (e.g. improved efficiency in allocating limited ISR assets) across runtime as dynamic events unfold on a simulated battlefield.

Researchers at ARL and the Network Science Collaborative Technology Alliance (NS-CTA), a collaborative research alliance funded by ARL, conducted experimentation to determine if automated network monitoring tools and task-aware agents deployed within an emulated tactical wireless network could potentially increase the retrieval of relevant data from heterogeneous distributed information nodes. ARL and NS-CTA required the capability to perform this experimentation over clusters of heterogeneous nodes with emulated wireless tactical networks where each node could contain different operating systems, application sets, and physical hardware attributes. Researchers utilized the Dynamically Allocated Virtual Clustering Management System (DAVC) to address each of the infrastructure support requirements necessary in conducting their experimentation. The DAVC is an experimentation infrastructure that provides the means to dynamically create, deploy, and manage virtual clusters of heterogeneous nodes within a cloud computing environment based upon resource utilization such as CPU load, available RAM and hard disk space. The DAVC uses 802.1Q Virtual LANs (VLANs) to prevent experimentation crosstalk and to allow for complex private networks. Clusters created by the DAVC system can be utilized for software development, experimentation, and integration with existing hardware and software. The goal of this paper is to explore how ARL and the NS-CTA leveraged the DAVC to create, deploy and manage multiple experimentation clusters to support their experimentation goals.

Research conducted under the ITA was extended through collaboration between ARL and IBM UK to characterize and define a software stack and tooling that has become the reference framework for network science experimentation in support for validation of theoretical research. This paper discusses the composition of the reference framework for experimentation resulting from the ARL/IBM UK collaboration and its use, by the Network Science Collaborative Technology Alliance (NS CTA)(2), in a recent network science experiment conducted at ARL. It also discusses how the experiment was modeled using the reference framework, the integration of two new components, the Apollo Fact-Finder(3) tool and the Medusa Crowd Sensing(4) application, the limitations identified and how they shall be addressed in future work.

Reducing the converter size is largely motivated by creating power supplies for micro-robotic platforms (with millimeter and milligram scales) without negatively impacting robotic system functionality. MEMS power passives are first presented where thin-film piezoelectric transformers and resonators are shown as an electromechanical approach to achieve ultra-miniature passives at the chip scale. Piezoelectric transformers fabricated with thin-film lead zirconate titanate (PZT) on silicon are measured and show similar to 60% efficiencies with 240 and 75 Omega loads. These transformers have resonant frequencies ranging between 14 and 20 MHz. Work towards creating transmission lines fabricated with air-core inductors and ferroelectric capacitors is also presented. Finally, a fullyintegrated bi-directional converter in CMOS is shown driving mm-scale robotic wings made with PZT. The converter's maximum efficiency is 77% at similar to 800 mu W load with 9V output and demonstrates >3x voltage boost in 0.13-mu m triple-well CMOS.

Although batteries offer a well known solution, limits on the chemistry developed to date constrain the energy density to 0.2 kWh/kg, whereas many hydrocarbon fuels have energy densities closer to 13 kWh/kg. The fundamental challenge remains: how efficiently and robustly can these widely available chemical fuels be converted into electricity in a millimeter to centimeter scale systems? Here we explore two promising technologies for high energy density power generators: thermophotovoltaics (TPV) and thermoelectrics (TE). These heat to electricity conversion processes are appealing because they are fully static leading to quiet and robust operation, allow for multifuel operation due to the ease of generating heat, and offer high power densities. We will present some previous work done in the TPV and TE fields. In addition we will outline the common technological barriers facing both approaches, as well as outline the main differences. Performance for state of the art research generators will be compared as well as projections for future practically achievable systems. A viable TPV or TE power source for a ten watt for one week mission can be built from a >10% efficient device which is achievable with current state of the art technology such as photonic crystals or advanced TE materials.

As on board state sensing and processing improves, actuation bandwidth is becoming a significant bottleneck that limits the performance of the entire closed loop system. The performance of the commercial products can be greatly enhanced through the implementation of classical control methods directly at the powertrain level. In this paper, reduced order open loop models for three representative commercially available powertrains were estimated and were compared with closed loop equivalents. Further performance improvement is realized by the addition of a static inverse to mitigate the steady state structured uncertainty of the system.

However, one of the major drawbacks for this technology currently, has been their poor endurance, usually below 10 minutes. This is a direct result of the inefficiencies inherent in their design. Often times, designers do not consider the various components in the vehicle design and match their performance to the desired mission for the vehicle. These vehicles lack a prescribed set of design guidelines or empirically derived design equations which often limits their design to selection of commercial off-the-shelf components without proper consideration of their affect on vehicle performance. In the current study, the design space for different vehicle configurations has been examined including insect flapping, avian flapping, rotary wing, and fixed wing, and their performance bounds are established. The propulsion system typical of a rotary wing vehicle is analyzed to establish current baselines for efficiency of vehicles at this scale. The power draw from communications is analyzed to determine its impact on vehicle performance. Finally, a representative fixed wing MAV is examined and the effects of adaptive structures as a means for increasing vehicle endurance and range are examined. This paper seeks to establish the performance bounds for micro air vehicles and establish a path forward for future designs so that efficiency may be maximized.

Each of these power circuits is generally implemented with discrete passive and active electronic components soldered next to the load devices on the printed circuit board. As greater levels of functionality are demanded within diminishing size and weight allowances, power management solutions will increasingly demand highly miniaturized power converters that are more tightly integrated into single-package solutions or even directly integrated onto the points of source and load. Experimental converters have demonstrated great potential in switching at very high frequencies (100+ MHz) to reduce the size of the requisite passive storage elements (inductors, transformers, and capacitors) to values that may be suitable for in-package or on-chip integration. However, integrating the passives into the same package as the active switching and control circuitry remains a significant fabrication challenge due to material incompatibility and inadequate performance of the passives. This paper discusses progress towards a fully integrated power converter module with a focus on microfabrication processes for both passive component development and wafer-level packaging. The passive components have been optimized for high performance at hundreds of MHz through the use of thick copper traces, intricate three-dimensional winding patterns. The capability of detaching the passives from the fabrication wafer produces a passives substrate that can serve directly as a routing platform for full integration of all components into a single-package solution.

We investigate the QD devices with various 1-mu m InAs /GaAs QD media placed in a 3-mu m base GaAs p-n junction. We found that n-charging of quantum dots (QDs) create potential barriers around QDs. QD growth between ultrathin AlGaAs layers leads to the formation of AlGaAs "fence" barriers, and reduces the wetting layers (WLs). The barriers around QDs and reduction of the wetting layer substantially suppress recombination processes via QDs. The n-doping of interdot space in QD media enhances electron extraction from QDs. All of our QD devices show short-circuit current, J(SC), higher than that of the reference cell, but smaller open-circuit voltage, V-OC.. In the QD devices, the short circuit currents increase by similar to 0.1 mA/cm(2) per dot layer. J(SC) reaches 28.4 mA/cm(2) in the device with QD media that combines dot charging, fence barriers, and WL reduction. C1 [Sablon, K. A.; Little, J. W.] US Army Res Lab, Adelphi, MD 20783 USA.

Both fieldable systems (man-portable or handheld) as well as benchtop systems in field and home base laboratories are desired for screening and attribution purposes. Laser Induced Breakdown Spectroscopy (LIBS) continues to show significant capability as a promising new tool for materials identification, matching, and provenance. With the use of the broadband, high resolution spectrometer systems, the LIBS devices can not only determine the elemental inventory of the sample, but they are also capable of elemental fingerprinting to signify sources of origin of various materials. We present the results of an initial study to differentiate and match spent cartridges from different manufacturers and countries. We have found that using Partial Least Squares Discriminant Analysis (PLS-DA) we are able to achieve on average 93.3% True Positives and 5.3% False Positives.

In this paper, we describe a software middleware architecture and implementation that allows fine-grained access control to the MMSDB at a dataset, table, and row level. Result sets from MMSDB queries issued in the client portal are filtered with the use of a policy enforcement proxy, with minimal changes to the existing client software and database. Before resulting data is returned to the client, policies are evaluated to determine if the user or role is authorized to access the data. Policies can be authored to filter data at the row, table or column level of a result set. The system uses various technologies developed in the International Technology Alliance in Network and Information Science (ITA) for policy-controlled information sharing and dissemination(1). Use of the Policy Management Library provides a mechanism for the management and evaluation of policies to support finer grained access to the data in the MMSDB system. The GaianDB is a policy-enabled, federated database that acts as a proxy between the client application and the MMSDB system.

Often times, the polarization signature of a manmade target is different than the surrounding background. Furthermore, that difference is often present even when the thermal signature of the same target blends into the background. This paper will present maritime, airborne and ground data sets of polarization signatures of several objects that allow detection when other methods fall short. C1 [Pezzaniti, J.

E-field sensors can likely complement traditional acoustic sensors, and help provide a more robust and effective solution for bullet detection and tracking. By far, the acoustic sensor is the most prevalent technology in use today for hostile fire defeat systems due to compact size and low cost, yet they come with a number of challenges that include multipath, reverberant environments, false positives and low signal-to-noise. Studies have shown that these systems can benefit from additional sensor modalities such as E-field sensors. However, E-field sensors are a newer technology that is relatively untested beyond basic experimental trials; this technology has not been deployed in any fielded systems. The U.S. Army Research Laboratory (ARL) has conducted live-fire experiments at Aberdeen Proving Grounds (APG) to collect data from E-field sensors. Three types of E-field sensors were included in these experiments: (a) an electric potential gradiometer manufactured by Quasar Federal Systems (QFS), (b) electric charge induction, or "D-dot" sensors designed and built by the Army Research Lab (ARL), and (c) a varactor based E-field sensor prototype designed by University of North Carolina-Charlotte (UNCC). Sensors were placed in strategic locations near the bullet trajectories, and their data were recorded. We analyzed the performance of each E-field sensor type in regard to small-arms bullet detection capability. The most recent experiment in October 2013 allowed demonstration of improved versions of the varactor and D-dot sensor types. Results of new real-time analysis hardware employing detection algorithms were also tested. The algorithms were used to process the raw data streams to determine when bullet detections occurred. Performance among the sensor types and algorithm effectiveness were compared to estimates from acoustics signatures and known ground truth. Results, techniques and configurations that might work best for a given sensor platform are discussed.

The IITET effort develops a reusable and extensible training architecture that supports the Army Learning Model and trains Manned-Unmanned Teaming (MUM-T) concepts to Shadow Unmanned Aerial Systems (UAS) payload operators. The training challenge of MUM-T during aviation operations is that UAS payload operators traditionally learn few of the scout-reconnaissance skills and coordination appropriate to MUM-T at the schoolhouse. The IITET effort leveraged the simulation experience and capabilities at NVESD and ARI's research to develop a novel payload operator training approach consistent with the Army Learning Model. Based on the training and system requirements, the team researched and identified candidate capabilities in several distinct technology areas. The training capability will support a variety of training missions as well as a full campaign. Data from these missions will be captured in a fully integrated AAR capability, which will provide objective feedback to the user in near-real-time. IITET will be delivered via a combination of browser and video streaming technologies, eliminating the requirement for a client download and reducing user computer system requirements. The result is a novel UAS Payload Operator training capability, nested within an architecture capable of supporting a wide variety of training needs for air and ground tactical platforms and sensors, and potentially several other areas requiring vignette-based serious games training.

Over the past decade, CCHF cases in humans have emerged in Turkey and reemerged in the Balkan countries, Ukraine and Tajikistan. Occupational contact with infected livestock has been recognized as a common cause of the disease. A cross-sectional seroprevalence study in livestock was conducted in farming communities of an endemic area in Bulgaria, southeastern Europe. Overall, 72% of the tested animals were positive for IgG antibodies to CCHF virus. By the time the animals were one-year old almost 50% had serologic evidence of CCHF infection, and by two years already 80% of them had been infected. The data obtained in this study reflect current situation of CCHF virus infection among livestock in Bulgaria. The results showed active CCHF virus circulation that poses risk for humans to be infected during contacts with animals and requires public health awareness.

We have previously demonstrated favorable PAS gas detection characteristics when the system dimensions are scaled to a micro-system design. This design includes quantum cascade laser (QCL)-based microelectromechanical systems (MEMS)-scale photoacoustic sensors that provide detection limits at parts-per-billion (ppb) levels for chemical targets. Current gas sensing research utilizes an ultra compact QCL, SpriteIR, in combination with a MEMS-scale photoacoustic cell for trace gas detection. At approximately one tenth the size of a standard commercially available QCL, SpriteIR is an essential element in the development of an integrated sensor package. We will discuss these results as well as the envisioned sensor prototype. Finally, expanding on our previously reported photoacoustic detection of condensed phase samples, we are investigating standoff photoacoustic chemical detection of these materials and will discuss preliminary results.

This method routinely exhibits detection limits at the parts-per-million (ppm) or parts-per-billion (ppb) level for gaseous samples. PAS also possesses favorable detection characteristics when the system dimensions are scaled to a microelectromechanical system (MEMS) design. One of the central issues related to sensor miniaturization is optimization of the photoacoustic cell geometry, especially in relationship to high acoustical amplification and reduced system noise. Previous work relied on a multiphysics approach to analyze the resonance structures of the MEMS scale photo acoustic cell. This technique was unable to provide an accurate model of the acoustic structure. In this paper we describe a method that relies on techniques developed from musical instrument theory and electronic transmission line matrix methods to describe cylindrical acoustic resonant cells with side branches of various configurations. Experimental results are presented that demonstrate the ease and accuracy of this method. All experimental results were within 2% of those predicted by this theory.

TI Speech Intelligibility While Wearing Full-Facepiece Air-Purifying Respirators SO JOURNAL OF OCCUPATIONAL AND ENVIRONMENTAL HYGIENE LA English DT Article DE Modified Rhyme Test; CBRN; communications; operational performance ID TELEPHONE AB Intelligible speech communication while wearing air-purifying respirators is critical for law enforcement officers, particularly when they are communicating with each other or the public. The National Institute for Occupational Safety and Health (NIOSH) requires a 70% overall performance rating to pass speech intelligibility certification for commercial chemical, biological, radiological, and nuclear air-purifying respirators. However, the speech intelligibility of certified respirators is not reported and the impact on operational performance is unknown. The objective of this effort was to assess the speech intelligibility of 12 certified air-purifying respirators and to predict their impact on operational performance. The NIOSH respirator certification standard testing procedures were followed. Regression equations were fit to data from studies that examined the impact of degraded speech intelligibility on operational performance of simple and complex missions. The impact of the tested respirators on operational performance was estimated from these equations. Performance ratings observed for each respirator were: MSA Millennium (90%), 3M FR-M40 (88%), MSA Ultra Elite (87%), Scott M110 (86%), North 5400 (85%), ScottM120 (85%), Avon C50 (84%), Avon FM12 (84%), Survivair Optifit (81%), Drager CDR 4500 (81%), Peltor-AOSafetyM-TAC (79%), and 3M FR-7800B (78%). The Millennium and FR-M40 had statistically significantly higher scores than the FR-7800B. The Millennium also scored significantly higher than the M-TAC. All of the tested respirators were predicted to have little impact on simple and complex mission performance times and on simple mission success rate. However, the regression equations showed that 75% of missions that require complex communications would be completed while wearing the Millennium, FR-M40, or Ultra Elite but that only 60% would be completed successfully while wearing the FR-7800B. These results suggest that some certified respirators may have a greater impact on speech communications than others.

This paper analyzes the spectral and azimuthal scattering characteristics of various types of individual furniture targets and compares these to humans. Radar cross section (RCS) values of furniture and humans are obtained using the finite difference time domain (FDTD) technique over the 1-5 GHz frequency range and the 0-360 azimuth angle range for both co- and cross-polarized scattering. In the case of furniture, RCS responses show to the highest returns when viewing the planar surfaces of the clutter objects. Objects consisting primarily of smaller planar surfaces with more complex geometrical features showed a more uniform response with no preferred orientation showing a larger response. Human RCS produced from the biological models showed a more constant RCS when viewing the co-polarized response, where the back produced the highest response due to the more planar surface. The cross-polarized response was more varied providing for a wider range of RCS values. C1 [Bufler, Travis D.; Narayanan, Ram M.] Penn State Univ, Dept Elect Engn, University Pk, PA 16802 USA.

However, such operation inevitably produces significant harmonics at the output, thereby degrading the performance of the microwave systems. An automated method for canceling harmonics generated by a power amplifier is presented in this paper. Automated tuning is demonstrated over 400 MHz of bandwidth with a minimum cancellation of 110 dB. The intended application for the harmonic cancellation is to create a linear radar transmitter for the remote detection of non-linear targets. The signal emitted from the non-linear targets is often very weak. High transmitter linearization is required to prevent the harmonics generated by the radar itself from masking this weak signal.

Atmospheric penetration properties, the ability to form high-resolution imagery with modest apertures, and available source power make the extremely high-frequency (EHF) portion of the spectrum promising for the development of radio frequency (RF) sensors capable of penetrating visual obscurants. Comprehensive phenomenology studies including polarization and backscatter properties of relevant targets are lacking at these frequencies. The Army Research Laboratory (ARL) is developing a fully-polarimetric frequency-modulated continuous-wave (FMCW) instrumentation radar to explore polarization and backscatter properties of in-situ rain, scattering from natural and man-made surfaces, and the radar cross section and micro-Doppler signatures of humans at EHF frequencies, specifically, around the 220 GHz atmospheric window. This work presents an overview of the design and construction of the radar system, hardware performance, data acquisition software, and initial results including an analysis of human micro-Doppler signatures.

The rail- SAR is located in a multi-use facility that also provides a base for research and development in the area of autonomous robotic navigation. Radar explosive hazard detection is one key sensordevelopment area to be investigated at this indoor facility. In particular, the mostly wooden, multi-story building houses a two (2) story housing structure and an open area built over a large sandbox. The housing structure includes reconfigurable indoor walls which enable the realization of multiple See-Through-The-Wall (STTW) scenarios. The open sandbox, on the other hand, allows for surface and buried explosive hazard scenarios. The indoor facility is not rated for true explosive hazard materials so all targets will need to be inert and contain surrogate explosive fills. In this paper we discuss the current system status and describe data collection exercises conducted using canonical targets and frequencies that may be of interest to designers of ultrawideband (UWB) airborne, ground penetrating SAR systems. A bi-static antenna configuration will be used to investigate the effects of varying airborne SAR parameters such as depression angle, bandwidth, and integration angle, for various target types and deployment scenarios. Canonical targets data were used to evaluate overall facility capabilities and limitations. These data is analyzed and summarized for future evaluations. Finally, processing techniques for dealing with RF multi-path and RFI due to operating inside the indoor facility are described in detail. Discussion of this facility and its capabilities and limitations will provide the explosive hazard community with a great airborne platform asset for sensor to target assessment.

Although the impulse-based architecture offers its own advantages, one of the important challenges is that when using this architecture it is very difficult to transmit a radar signal with an arbitrary bandwidth and shape. This feature is crucial for the radar to be compliant with the local frequency authority. In addition, being able to transmit signals with an arbitrary spectral shape is an important step in creating the next generation of smart (cognitive) radars. Therefore, we have designed a next-generation prototype radar to take advantage of the stepped frequency architecture. The design and building of the radar hardware is underway. In this paper, we study the radar transmit and acquisition scheme; the trade-offs between SAR image performance and various key radar parameters; and data reconstruction techniques for radar signals with an arbitrary spectrum. This study demonstrates performance, provides some guidelines for the radar design, and serves as a foundation for the signal and image processing stage. C1 US Army Res Lab, Adelphi, MD 20783 USA.

Two energy detection techniques are used to select an unoccupied frequency. The first technique requires the fast Fourier transform and a weighting function to test the energy in neighboring frequency bins; both of these procedures may require a high degree of computational resources. The second technique uses multirate digital signal processing and the fast binary search techniques to lower the overall computational complexity while satisfying the requirements for an unoccupied frequency.

One technology that is capable of separating RF electronic targets from clutter, however, is nonlinear radar. Presented in this paper is a combination of stepped-frequency ultra-wideband radar with nonlinear detection. By stepping the transmit frequency across an ultra-wide bandwidth and recording the amplitude and phase of the harmonic return signal, a nonlinear frequency response of the radar environment is constructed. An inverse Fourier transform of this response reveals the range to a nonlinear target.

However, there is no control of the radiated spectrum in this system. As part of ARL's Partnerships in Research Transition (PIRT) program, the above deficiency is addressed by the design of a Stepped-Frequency Radar (SFR) which allows for precise control over the radiated spectrum, while still maintaining an effective ultra-wide bandwidth. The SFR utilizes a frequency synthesizer which can be configured to excise prohibited and interfering frequency bands and also implement frequency-hopping capabilities. The SFR is designed to be a forward-looking groundpenetrating (FLGPR) Radar utilizing a uniform linear array of sixteen (16) Vivaldi notch receive antennas and two (2) Quad-ridge horn transmit antennas. While a preliminary SFR consisting of four (4) receive channels has been designed, this paper describes major improvements to the system, and an analysis of expected system performance. The 4-channel system will be used to validate the SFR design which will eventually be augmented in to the full 16-channel system. The SFR has an operating frequency band which ranges from 300 2000 MHz, and a minimum frequency step-size of 1 MHz. The radar system is capable of illuminating range swaths that have maximum extents of 30 to 150 meters (programmable). The transmitter has the ability to produce approximately -2 dBm/MHz average power over the entire operating frequency range. The SFR will be used to determine the practicality of detecting and classifying buried and concealed landmines and IEDs from safe stand-off distances.

In particular, tip-over events can potentially end or substantially disrupt mission performance and jeopardize asset recovery. To facilitate recovery from tip-over events (i.e. self-righting), the robot should be able to discern the ground angle on which it lies even when it is not in its preferred upright orientation. In this paper, we present a methodology for determining unknown ground angles using recursive Bayesian estimation. First, we briefly review our previous framework for autonomous self-righting, which we use to generate conformation space maps correlating stable robot configurations and orientations on various ground angles. Using these maps, we compare sensor orientation to predicted orientation for the robot configuration on all mapped ground angles. We then compute the best fit ground angle and assign it a confidence level based on filters such as predicted stability margin and measured rate of orientation change. We compare ground angle prediction error as a function of time using a variety of methods, and show a sensitivity analysis comparing accuracy as a function of the discretization of the ground angle dimension of the conformation space map. Finally, we demonstrate a physical robot's ability to self-right on unknown ground using this methodology. C1 [Collins, Jason] Engility Corp, 3750 Centerview Dr, Chantilly, VA 20151 USA.

The method provides an estimate of the global horizontal position of a vehicle strictly based on finding a geometric match between a map of observed tree stems, scanned in 3D by Light Detection and Ranging (LiDAR) sensors onboard the vehicle, to another stem map generated from the structure of tree crowns analyzed from high resolution aerial orthoimagery of the forest canopy. Extraction of stems from 3D data is achieved by using Support Vector Machine (SVM) classifiers and height above ground filters that separate ground points from vertical stem features. Identification of stems from overhead imagery is achieved by finding the centroids of tree crowns extracted using a watershed segmentation algorithm. Matching of the two maps is achieved by using a robust Iterative Closest Point (ICP) algorithm that determines the rotation and translation vectors to align the datasets. The alignment is used to calculate the absolute horizontal location of the vehicle. The method has been tested with real-world data and has been able to estimate vehicle geoposition with an average error of less than 2 m. It is noted that the algorithm's accuracy performance is currently limited by the accuracy and resolution of aerial orthoimagery used. The method can be used in real-time as a complement to the Global Positioning System (GPS) in areas where signal coverage is inadequate due to attenuation by the forest canopy, or due to intentional denied access. The method has two key properties that are significant: i) It does not require a priori knowledge of the area surrounding the robot. ii) Uses the geometry of detected tree stems as the only input to determine horizontal geoposition.

Accurate modeling of the world around the robot and describing the interaction of the robot with the world greatly increases the ability of the robot to act autonomously. This paper demonstrates the ability of autonomous robotic teams to find objects of interest. A novel feature of our approach is the object discovery and the use of it to augment the mapping and navigation process. The generated map can then be decomposed into into semantic regions while also considering the distance and line of sight to anchor points. The advantage of this approach is that the robot can return a dense map of the region around an object of interest. The robustness of this approach is demonstrated in indoor environments with multiple platforms with the objective of discovering objects of interest.

Our approach generates an over-segmentation based on voxel cloud connectivity, where a modified k-means algorithm selects supervoxel seeds and associates similar neighboring voxels to form segments. Given the data stream from a potentially mobile sensor, we solve for the camera transformation between consecutive frames using a joint optimization over point correspondences and image appearance. The aligned point cloud may then be integrated into a consistent model coordinate frame. Previously labeled points are used to mask incoming points from the new frame, while new and previous boundary points extend the existing segmentation. We evaluate the algorithm on newly-generated RGB-D datasets. C1 [Owens, Jason L.] Army Res Lab, Aberdeen Proving Ground, MD 21005 USA. [Osteen, Philip R.] Engil, Chantilly, VA USA.

Canid is a free-standing, power-autonomous quadrupedal machine constructed from standard commercially available electromechanical and structural elements, incorporating compliant C-shaped legs like those of the decade old RHex design, but departing from that standard (and, to the best of our knowledge, from any prior) robot platform in its parallel actuated elastic spine. We have used a commercial modeling package to develop a finite-element model of the actuated, cable-driven, rigid-plate-reinforced harness for the carbon-fiber spring that joins the robot's fore-and hind-quarters. We compare a numerical model of this parallel actuated elastic spine with empirical data from preliminary physical experiments with the most important component of the spine assembly: the composite leaf spring. Specifically, we report our progress in tuning the mechanical properties of a standard modal approximation to a conventional compliant beam model whose boundary conditions represent constraints imposed by the actuated cable driven vertebral plates that comprise the active control affordance over the spine. We conclude with a brief look ahead at near-term future experiments that will compare predictions of this fitted composite spring model with data taken from the physical spine flexed in isolation from the actuated harness.

Size, weight, power and cost constraints impose significant practical limitations on perception systems intended for small ground robots. In recent years, the Army Research Laboratory (ARL) developed a LADAR architecture based on a MEMS mirror scanner that fundamentally improves the trade-offs between these limitations and sensor capability. We describe how the characteristics of a highly developed prototype correspond to and satisfy the requirements of autonomous navigation and the experimental scenarios of the ARL Robotics Collaborative Technology Alliance (RCTA) program. In particular, the long maximum and short minimum range capability of the ARL MEMS LADAR makes it remarkably suitable for a wide variety of scenarios from building mapping to the manipulation of objects at close range, including dexterous manipulation with robotic arms. A prototype system was applied to a small (approximately 50 kg) unmanned robotic vehicle as the primary mobility perception sensor. We present the results of a field test where the perception information supplied by the LADAR system successfully accomplished the experimental objectives of an Integrated Research Assessment (IRA).

These "rapidly fielded" systems did not follow the standard Department of Defense procurement process to become what is termed a "Program of Record", or PoRs, meaning a program which has a funding stream to continue fielding and support. Now that the war effort is winding down, these systems will either be terminated or become PoR. One such system is the Buckeye system. This system provides very high-definition 3D photo capabilities which can provide Army units with near real-time pictures of the terrain which they are about to walk through or, in the case of helicopters, land on. To become a Program of Record, the Army must determine if the system provides the most cost-beneficial solution. In this paper, we evaluate the value of systems which can be used to evaluate terrain data for Army units using a process known as the Systems Decision Process.

Analysis of the experiment resulted in two major findings: (1) UI composition and information presentation have an impact on human trust and cooperation behavior, and (2) a strong positive correlation between Situation Awareness (SA) and performance is confirmed. There was a significant effect for UI levels on our main performance metric, total participant dining points, at the p= 0.041 level. Also, there was a marginal effect for UI levels on participant cooperation at the p= 0.084 level. Total participant dining points and SA were strongly correlated, r (92) = 0.62. Similarly, participant cooperation and SA were strongly correlated, r (92) = 0.61. C1 [Onal, Emrah] SA Technol, Lewisville, TX 75057 USA.

To better understand the emerging topic of transparency, we have varied the levels of information that a robotic teammate provided to participants and measured their trust responses. Additionally, we varied the modality (text, auditory, and graphic) the robotic teammate used when communicating with the participant. Participants reported higher trust levels in the constant level of information, the condition in which they were provided with a constant information stream from the robotic team member. Differences in communication modality had little influence on trust ratings. C1 [Sanders, Tracy L.; Hancock, P. A.] Univ Cent Florida, Inst Simulat & Training, Orlando, FL 32816 USA.

The modeling and analysis of these components usually require multi-disciplinary approaches. This paper presents a modeling and dynamic analysis of a distributed cyber control system for situational awareness by taking advantage of control theory and time Petri net. Linear time-invariant systems are used to model the target system, attacks, assets influences, and an anomaly-based intrusion detection system. Time Petri nets are used to model the impact and timing relationships of attacks, vulnerability, and recovery at every node. To characterize those distributed control systems that are perfectly attackable, algebraic and topological attackability conditions are derived. Numerical evaluation is performed to determine the impact of attacks on distributed control system.

But, there are two major challenges to achieve this goal. First, it is very costly to capture the experience of experts for the complex task of cyber analysis using traditional approaches such as protocol analysis. Second, it is difficult to identify previous experiences of experts that are relevant to the dynamic context of an analyst's cyber analysis task. To address the first challenge, a system has been developed to capture non-intrusively the analytical reasoning processes of analysts. To tackle the second challenge, this paper presents an effective and efficient approach for retrieving relevant experiences based on the dynamically changing context of cyber analysis. We define an experience as a process of analytical reasoning and adopt an Action-Observation-Hypothesis (A-O-H) model to represent the processes in cyber analysis. Based on this model, a tool for capturing and supporting the analytical reasoning processes is shown to be able to support the elusive cognitive process in dynamic cyber situations. The experience retrieval approach of this paper supports the efficient experience retrieval, and dynamically updates the results as the context of analysis evolves. The experience retrieval approach is evaluated, based on the precision and recall with respect to the ground truth. The evaluation results suggest that the proposed approach supports significantly the analytical reasoning of analysts by leveraging the experiences of experts.

Hydrellia pakistanae and Hydrellia balciunasi were introduced for classical biological control of the invasive aquatic weed Hydrilla verticillata in the 1980s and acquired T. columbiana post-release. Several life history parameters of T. columbiana were investigated in the laboratory, including fecundity, egg shape and size, number and location of egg(s) deposited per host, preferred host age, description and number of instars, mode of respiration and host-selection behaviour. Field studies included seasonal abundance of T. columbiana and the introduced Hydrellia spp., parasitism levels, overwintering stage and adult winter sex ratio. T. columbiana is a synovigenic solitary endoparasitoid that developed from egg to adult in 21.9 +/- 0.2 days under laboratory conditions. Eggs of T. columbiana are hydropic, hymenopteriform in shape and possess a double membrane. Larvae have three instars; first instars have sclerotised mandibles, bifurcated abdominal appendages and are free floating in the host's haemolymph. Second and third instars are grub-like and remain attached to the host's tracheal system until pupation. Individual females produced on average 23.2 +/- 0.6 eggs and survived 15.6 +/- 1.8 days. Highest parasitism levels of early and intermediate stage pupae occurred when wasps were 8-9 days old. Field parasitism rates of the two introduced Hydrellia spp. averaged 19.1%. C1 [Coon, B.

TI The influence of edge effects on crack propagation in snow stability tests SO CRYOSPHERE LA English DT Article ID SLAB AVALANCHES; SHEAR FRACTURE; MECHANISM; FAILURE; ENERGY; LAYERS; SIZE AB The Extended Column Test (ECT) and the Propagation Saw Test (PST) are two commonly used tests to assess the likelihood of crack propagation in a snowpack. Guidelines suggest beams with lengths of around 1 m, yet little is known about how test length affects propagation. Thus, we performed 163 ECTs and PSTs 1.0-10.0 m long. On days with full crack propagation in 1.0-1.5 m tests, we then made videos of tests 2.0-10.0 m long. We inserted markers for particle tracking to measure collapse amplitude, propagation speed, and wavelength. We also used a finite element (FE) model to simulate the strain energy release rate at fixed crack lengths. We find that (1) the proportion of tests with full propagation decreased with test length; (2) collapse was greater at the ends of the beams than in the centers; (3) collapse amplitude was independent of beam length and did not reach a constant value; (4) collapse wavelengths in the longer tests were around 3 m, two times greater than what is predicted by the anticrack model. We also confirmed the prediction that centered PSTs had double the critical length of edge PSTs. Based on our results, we conclude that cracks propagated more frequently in the shorter tests because of increased stress concentration from the far edge. The FE model suggests this edge effect occurs for PSTs of up to 2m long or a crack to beam length ratio >= 0.20. Our results suggest that ECT and PST length guidelines may need to be revisited.

Due to the hygroscopy of AN, this HME is expected to be an intermediate electrical conductivity material (IECM), defined here as one having electrical conductivity greater than soils, which have conductivities 0.1 to 1000 mS.m(-1) but less than metals, which have electrical conductivities on the order of 10 MS.m(-1). Our preliminary experimental and numerical modeling have established that AN-containing HME in the subsurface can, in all likelihood, be detected by electromagnetic exploration geophysics techniques, specifically by ground penetrating radar (GPR) and by electromagnetic induction (EMI). The electromagnetic induction signatures of HME for these techniques are distinctive. For example, in the case of EMI, the maximum quadrature response frequencies for IECM targets have been found to be greater than 100 kHz C1 [Grant, Steven A.; Barrowes, Benjamin E.; Arcone, Steven A.] US Army Engineer Res & Engn Ctr, 72 Lyme Rd, Hanover, NH 03755 USA.

We used the MetalMapper sensor, from which extrinsic and intrinsic parameters are determined by the combined Differential Evolution (DE) and Ortho-Normalized Volume Magnetic Source (ONVMS) algorithms. The inversion provides spatial locations and intrinsic time-series total ONVMS principal eigenvalues. These are fit to a power-decay empirical model, providing dimensionality reduction to 3 coefficients (k, b, and g) for polarizability decay. Anomaly target features are grouped using the unsupervised clustering Weighted-Pair Group Method with Averaging (WPGMA) algorithm. Central elements of each cluster are dug, and the results are used to train the next round of dig requests. A Naive Bayes classifier is used as a supervised learning algorithm, in which the product of each feature's independent probability density represents each class of UXO in the feature space. We request ground truths for anomalies in rounds, until there are no more Targets of Interest (TOT) in consecutive requests. This fully automatic procedure requires no expert intervention, saving time and money. Naive Bayes outperformed previous efforts with Gaussian Mixture Models(GMM) in all cases.

This has the potential to provide smaller, cheaper, and lower bandwidth imaging systems. To properly assess the value of such systems, it is necessary to fully characterize the image quality, including artifacts, sensitivity to noise, and CS limitations. Full resolution imagery of an eight tracked vehicle target set at range was used as an input for simulated single-pixel CS camera measurements. The CS algorithm then reconstructs images from the simulated single-pixel CS camera for various levels of compression and noise. For comparison, a traditional camera was also simulated setting the number of pixels equal to the number of CS measurements in each case. Human perception experiments were performed to determine the identification performance within the trade space. The performance of the nonlinear CS camera was modeled with the Night Vision Integrated Performance Model (NVIPM) by mapping the nonlinear degradations to an equivalent linear shift invariant model. Finally, the limitations of compressive sensing modeling will be discussed. C1 [Du Bosq, Todd W.; Haefner, David P.; Preece, Bradley L.] US Army RDECOM CERDEC NVESD, Ft Belvoir, VA 22060 USA.

The recent Defense Advanced Research Projects Agency (DARPA) Super Resolution Vision System (SRVS) program developed novel post-processing system components to mitigate turbulence effects on visible and infrared sensor systems. As part of the program, the US Army RDECOM CERDEC NVESD and the US Army Research Laboratory Computational & Information Sciences Directorate (CISD) collaborated on a field collection and atmospheric characterization of a two-handed weapon identification dataset through a diurnal cycle for a variety of ranges and sensor systems. The robust dataset is useful in developing new models and simulations of turbulence, as well for providing as a standard baseline for comparison of sensor systems in the presence of turbulence degradation and mitigation. In this paper, we describe the field collection and atmospheric characterization and present the robust dataset to the defense, sensing, and security community. In addition, we present an expanded model validation of turbulence degradation using the field collected video sequences.

Information input into the model is the time dependence of P-infinity and T, two parameters that describe observer-sensor-atmosphere-range-target properties of the target acquisition system for the case where neither the sensor nor target is moving. The parameter Poo can be calculated by the NV-IPM model and T is estimated empirically from P. In this model n, m and k are integers and k can be less than, equal to or greater than n Increasing n and k results in a substantial increase in target acquisition probabilities. Because the sensors are networked, a target is said to be detected the moment the first of the k observers declares the target. The model applies to time-limited or time-unlimited search, and applies to any imaging sensors operating in any wavelength band provided each sensor can be described by Poo and T parameters.

S. Army Aviation and Missile Research, Development, and Engineering Center (AMRDEC) has specialized in characterizing the performance of infrared (IR) imaging systems in the laboratory and field. In the late 90's, AMRDEC developed the Automated IR Sensor Test Facility (AISTF) which allowed efficient deployment testing of aviation and missile IR sensor systems. More recently, AMRDEC has tested many uncooled infrared (UCIR) sensor systems that have size, weight, power, and cost (SWAPC) benefits for certain fielded U. S. Army imaging systems. To compensate for relatively poor detector sensitivities, most UCIR systems operate with very fast focal ratio or F-number (f/#) optics. AMRDEC has recently found that measuring the Noise Equivalent Temperature Difference (NETD) with traditional techniques used with cooled infrared systems produce biased results when applied to systems with faster f/# values or obscurations. Additionally, in order to compare these camera cores or sensor systems to one another, it is imperative to scale the NETD values for f/#, focus distance, and waveband differences accurately. This paper will outline proper measurement techniques to report UCIR camera core and system-level NETD, as well as demonstrate methods to scale the metric for these differences.

Microbial cultures, which were spiked with DSSN+, exhibit a similar to 2.2-fold increase in charge collected, a similar to 3.1-fold increase in electrode colonization by S. oneidensis, and a similar to 1.7-fold increase in coulombic efficiency from 51 +/- 10% to an exceptional 84 +/- 7% without obvious toxicity effects. Direct microbial biofilm voltammetry reveals that DSSN+ rapidly and sustainably increases cytochrome-based direct electron transfer and subsequently increases flavin-based mediated electron transfer. Control experiments indicate that DSSN+ does not contribute to the current in the absence of bacteria.

The nondestructive technique of the falling weight deflectometer and the layered elastic model are commonly used to identify pavement structural condition. The approach in this article is mechanistic-empirical, with the intent to correlate the strain at the bottom of the asphalt layer with the number of coverages to failure. Strains were computed through mathematical approximation of the deflection basin measured at failure. The proposed asphalt criterion showed the same trend of the subgrade strain criterion developed in conjunction with the reformulation of the California bearing ratio (CBR)-Beta design criteria. The approach provided encouraging results when compared with the other analyses in the development of the CBR-Beta criteria. The database was from the full-scale flexible pavement testing at the US Army Engineer Research and Development Center in Vicksburg, MS, USA.

TI Full-scale field testing of precast Portland cement concrete panel airfield pavement repairs SO INTERNATIONAL JOURNAL OF PAVEMENT ENGINEERING LA English DT Article DE precast; rapid repair; PCC; full-scale; airfields AB A series of various sized Portland cement concrete (PCC) airfield repairs was performed using precast panels. The repairs received simulated C-17 aircraft traffic, and each repair was trafficked to failure. A heavy weight deflectometer was used to measure the panels' response to loading with increasing traffic applications. The results of traffic testing were used to evaluate the suitability of the precast panel repair technique for rapidly repairing PCC airfield pavements. Test results showed that the repair system was capable of supporting at least 5000 passes and possibly as many as 10,000 passes of C-17 traffic. Compared with other rapid airfield repair methods, the precast panel repair alternative may provide similar return-to-service timeliness and traffic performance at a slightly higher cost. Modifications to the system design and placement procedures are recommended to improve the field performance of the panels.

Design/methodology/approach - The paper opted for a survey design using the Screen for Caregiver Burden, Perceived Stress Scale, Short Form 36 Health Survey, Symptom Questionnaire, Center for Epidemiologic Depression, Sense of Coherence, Coping Resources Inventory, and the Personal Resource Questionnaire (PRQ-85). A total of 202 participants with 53 Latino caregivers (majority were Mexican-Americans) and 149 NH white caregivers also completed an in-depth qualitative interview describing their experience as caregivers. Findings - Latino caregivers, as compared to NH white caregivers, have higher subjective and objective caregiver burden and lower general health, social function, and physical function. They also reported higher levels of bodily pain and somatic symptoms. Caregivers experience a great deal of stress that can adversely affect their emotional and physical well-being. Latino cultural values influence the meaning ascribed to caregiving and how caregivers attempt to balance a perceived duty to family. Research limitations/implications - The sample was a convenience sample of caregivers responding to an invitation to participate. The Latino sample included primarily caregivers of Mexican-American descent and represented Latinos living in the South West section of the USA. Future research needs to include Latinos of diverse nationalities. Practical implications - The paper points out crucial differences between NH white and Latino caregivers. Understanding how Latino cultural values influence how Latinos perform and feel about caregiving duties may facilitate support for caregivers. Originality/value - This paper fulfills an identified need to study Latino caregiving.

TI Optimal Dredge Fleet Scheduling Within Environmental Work Windows SO TRANSPORTATION RESEARCH RECORD LA English DT Article ID GENERALIZED ASSIGNMENT PROBLEM; ALGORITHM AB The U.S. Army Corps of Engineers oversees dredging in hundreds of navigation projects annually, through its fleet of government equipment and through individual contracts with private industry. The research presented here sought to examine the decision to allocate dredge resources to projects systemwide under necessary constraints. These constraints included environmental restrictions on when dredging could take place in response to the migration patterns of turtles, birds, fish, and other wildlife; dredge equipment resource availability; and varying equipment productivity rates that affected project completion times. The paper discusses problem definition and model formulation of optimal dredge fleet scheduling within environmental work windows. In addition, a sensitivity analysis was conducted to provide decision makers with quantitative insights into dredging program efficiency gains that could be realized systemwide if environmental restrictions were relaxed. Opportunities exist to provide decision makers with quantitative insights into how efficiencies might be obtained if targeted research were to show that particular restricted periods could be relaxed without adverse consequences to sensitive and endangered species.

Scully, Brandan TI Waterway Performance Monitoring with Automatic Identification System Data SO TRANSPORTATION RESEARCH RECORD LA English DT Article AB Fiscal constraints at the federal level drive the need for more robust and objective performance evaluation methodologies for use by the U.S. Army Corps of Engineers as it carries out its civil works mission in support of the nation's water resources infrastructure. One specific area of need concerns functional performance evaluation of dredged navigation channels at the local level as well as performance evaluation of systems of navigation projects. The nationwide automatic identification system (NAIS) for vessels that operate in coastal waters was instituted after the terrorist attacks of September 2001 and is maintained by the U.S. Coast Guard. The system constitutes an enabling technology to provide the data required for quantitative performance assessments of corps-maintained navigation infrastructure. In this paper, several applications are presented of archival NAIS data toward waterway performance evaluation. An assessment and comparison also are presented of several deep-draft coastal ports with respect to the sensitivity of vessel transit timing to tidal elevations. The NAIS data archive is applied toward a point-to-point transit time monitoring strategy at the local and regional levels. The corps confronts an uncertain fiscal outlook and constrained budgets for annual operations and maintenance activities. These metrics, as well as other potential applications of archival NAIS data, can play a valuable role in the provision of objective, quantitative assessments of waterway performance.

One such capability is to explain anomalous sensor readings. Towards that end, in this paper, we build an automated anomaly clarification service, called ClariSense. It explains sensor anomalies using social network feeds. Explanation goes beyond detection. When a sensor network detects anomalous conditions, our system automatically suggests hypotheses that explain the likely causes of the anomaly to a human by identifying unusual social network feeds that seem to be correlated with the sensor anomaly in time and in space. To evaluate this service, we use real-time data feeds from the California traffic system that shares vehicle count and traffic speed on major California highways at 5 minute intervals. When anomalies are detected, our system automatically diagnoses their root cause by correlating the anomaly with feeds on Twitter. The identified cause is then compared to official traffic and incident reports, showing a great correspondence with ground truth.

Millions of people, most from resource-constrained countries, seek treatment every year for dengue-related disease. Despite more than 70 years of effort, a safe and efficacious vaccine remains unavailable. Antidengue antiviral drugs also do not exist despite attempts to develop or repurpose drug compounds. Gaps in the knowledge of dengue immunology, absence of a validated animal or human model of disease, and suboptimal assay platforms to measure immune responses following infection or experimental vaccination are obstacles to drug and vaccine development efforts. The limited success of one vaccine candidate in a recent clinical endpoint efficacy trial challenges commonly held beliefs regarding potential correlates of protection. If a dengue vaccine is to become a reality in the near term, vaccine developers should expand development pathway explorations beyond those typically required to demonstrate safety and efficacy.

Experimental seismic, blast, and fire testing of concrete filled fiber reinforced polymer (FRP) tube (CFFT) columns have unveiled the superb multihazard performance of this particular system. As a result of the CFFT system exhibiting superior seismic performance to RC columns in shake table experiments conducted at the University of Nevada, an analytical model calibrated with experimental results was used to quantify and compare the seismic resilience of the CFFT system to conventional RC columns through residual axial capacity analysis after experiencing two levels of biaxial ground motion. Additionally, the results of experimental axial capacity tests following experimental blast and fire testing conducted by the University of Connecticut were used to substantiate the CFFT system as a multihazard resilient alternative to conventional RC bridge columns.

In addition, several construction benefits of the CFFT system have been noted during previously conducted and current experimental studies making the CFFT system an applicable option for acceleration bridge construction (ABC). To further extend the applicability of the system, the blast resilience of CFFT bridge columns was studied through experimental blast testing by the University of Connecticut (UConn) in collaboration with the U. S. Army Engineer Research and Development Center (ERDC). Two one-fifth scale CFFT columns were subjected to two levels of realistic bridge column blast threats, and their performance during and after blast loading was studied. The CFFT columns were able to withstand significant blast threats without compromising axial performance after the extreme event validating this system for the accelerated construction of blast resilient bridge columns.

However, the capacity of connections in compression, estimated by buckling instability theories, remains a subject of debate among subject matter experts. The equations provided by North American Standards seem to produce very conservative results in many typical gusset plate configurations found in existing steel bridges. Furthermore, the computational analysis of connections consisting of built-up sections is complex due to its geometry, boundary conditions, load conditions and interactions between elements (plates and rivets). The main objective of this study is to perform computational non-linear buckling analyses of typical steel bridge gusset plate connections using the commercial software Abaqus CAE. The study was divided in the following two stages: i) study the effect of thickness reductions and increments of unbraced length in the gusset plates buckling capacity and ii) compare the methods used to estimate the buckling capacity. The stability analysis demonstrated that for a reduction of 15% of its original thickness and an increment of 30% of its unbraced length, the gusset plate have a structural reduction capacity of 20% and 6%, respectively. Finally, according to the FEA, results showed that the Thornton method used in the Federal Highway Administration guidance leads to highly conservative results. The Yoo method is in very close agreement to the FEA, and this study recommends its use for future applications.

TI A Hantavirus Pulmonary Syndrome (HPS) DNA Vaccine Delivered Using a Spring-powered Jet Injector Elicits a Potent Neutralizing Antibody Response in Rabbits and Nonhuman Primates SO CURRENT GENE THERAPY LA English DT Article DE DNA vaccine; hantavirus; jet injection ID HANTAAN VIRUS; ANDES VIRUS; SIN-NOMBRE; HEMORRHAGIC-FEVER; PROTECTS HAMSTERS; RENAL SYNDROME; IMMUNIZATION; INFECTIONS; MODEL; HFRS AB Sin Nombre virus (SNV) and Andes virus (ANDV) cause most of the hantavirus pulmonary syndrome (HPS) cases in North and South America, respectively. The chances of a patient surviving HPS are only two in three. Previously, we demonstrated that SNV and ANDV DNA vaccines encoding the virus envelope glycoproteins elicit high-titer neutralizing antibodies in laboratory animals, and (for ANDV) in nonhuman primates (NHPs). In those studies, the vaccines were delivered by gene gun or muscle electroporation. Here, we tested whether a combined SNV/ANDV DNA vaccine (HPS DNA vaccine) could be delivered effectively using a disposable syringe jet injection (DSJI) system (PharmaJet, Inc). PharmaJet intramuscular (IM) and intradermal (ID) needle-free devices are FDA 510(k)-cleared, simple to use, and do not require electricity or pressurized gas. First, we tested the SNV DNA vaccine delivered by PharmaJet IM or ID devices in rabbits and NHPs. Both IM and ID devices produced high-titer anti-SNV neutralizing antibody responses in rabbits and NHPs. However, the ID device required at least two vaccinations in NHP to detect neutralizing antibodies in most animals, whereas all animals vaccinated once with the IM device seroconverted. Because the IM device was more effective in NHP, the Stratis (R) (PharmaJet IM device) was selected for follow-up studies. We evaluated the HPS DNA vaccine delivered using Stratis (R) and found that it produced high-titer anti-SNV and anti-ANDV neutralizing antibodies in rabbits (n=8/group) as measured by a classic plaque reduction neutralization test and a new pseudovirion neutralization assay. We were interested in determining if the differences between DSJI delivery (e. g., high-velocity liquid penetration through tissue) and other methods of vaccine injection, such as needle/syringe, might result in a more immunogenic DNA vaccine. To accomplish this, we compared the HPS DNA vaccine delivered by DSJI versus needle/syringe in NHPs (n=8/group). We found that both the anti-SNV and anti-ANDV neutralizing antibody titers were significantly higher (p-value 0.0115) in the DSJI-vaccinated groups than the needle/syringe group. For example, the anti-SNV and anti-ANDV PRNT50 geometric mean titers (GMTs) were 1,974 and 349 in the DSJI-vaccinated group versus 87 and 42 in the needle/syringe group. These data demonstrate, for the first time, that a spring-powered DSJI device is capable of effectively delivering a DNA vaccine to NHPs. Whether this HPS DNA vaccine, or any DNA vaccine, delivered by spring-powered DSJI will elicit a strong immune response in humans, requires clinical trials.

A better understanding of the metabolic processes required during the asexual blood-stage reproduction will enhance our basic knowledge of P. falciparum and help identify critical metabolic reactions and pathways associated with blood-stage malaria. We developed a metabolic network model that mechanistically links time-dependent gene expression, metabolism, and stage-specific growth, allowing us to predict the metabolic fluxes, the biomass production rates, and the timing of production of the different biomass components during the IDC. We predicted time-and stage-specific production of precursors and macromolecules for P. falciparum (strain HB3), allowing us to link specific metabolites to specific physiological functions. For example, we hypothesized that coenzyme A might be involved in late-IDC DNA replication and cell division. Moreover, the predicted ATP metabolism indicated that energy was mainly produced from glycolysis and utilized for non-metabolic processes. Finally, we used the model to classify the entire tricarboxylic acid cycle into segments, each with a distinct function, such as superoxide detoxification, glutamate/glutamine processing, and metabolism of fumarate as a byproduct of purine biosynthesis. By capturing the normal metabolic and growth progression in P. falciparum during the IDC, our model provides a starting point for further elucidation of strain-specific metabolic activity, host-parasite interactions, stress-induced metabolic responses, and metabolic responses to antimalarial drugs and drug candidates.

Two of the haptens, with a 2-oxopropyl functionality at either C6, or at both the C3 and C6 positions on the 4,5-epoxymorphinan framework, as well as the third hapten (DiAmHap) with diamido moieties at both the C3 and C6 positions, should be much more stable in solution, or in vivo in a vaccine, than a hapten with an ester in one of those positions, as found in many heroin-based haptens. A "classical" opioid synthetic scheme enabled the formation of a 3-amino-4,5-epoxymorphinan which could not be obtained using palladium chemistry. Our vaccines are aimed at the reduction of the abuse of heroin and, as well, at the reduction of the effects of its predominant metabolites, 6-acetylmorphine and morphine. One of the haptens, DiAmHap, has given interesting results in a heroin vaccine and is clearly more suited for the purpose than the other two haptens. C1 [Li, Fuying; Cheng, Kejun; Antoline, Joshua F.

TI Electronic stability and electron transport properties of atomic wires anchored on the MoS2 monolayer SO PHYSICAL CHEMISTRY CHEMICAL PHYSICS LA English DT Article ID TRANSITION-METAL DICHALCOGENIDES; SCANNING TUNNELING MICROSCOPE; NANOPARTICLES; GRAPHENE; SE; TE; SEMICONDUCTORS; PROGRESS; ARRAYS; X=S AB The stability, electronic structure, and electron transport properties of metallic monoatomic wires anchored on the MoS2 monolayer are investigated within the density functional theory. The anchoring of the atomic wires on the semiconducting monolayer significantly modifies its electronic properties; the metallic characteristics of the assembled monolayers appear in the density of states and band structure of the system. We find that Cu, Ag and Au wires induce the so-called n-type doping effect, whereas Pt wires induce a p-type doping effect in the monolayer. The distinctly different behavior of Pt-MoS2 compared to the rest of the metallic wires is reflected in the calculated current-voltage characteristics of the assembled monolayers with a highly asymmetric behavior of the out-of-the-plane tunneling current with respect to the polarity of the external bias. The results of the present study are likely to extend the functionality of the MoS2 monolayer as a candidate material for the novel applications in the areas of catalysis and optoelectronic devices.

TI A simple method for fabricating silver nanotubes SO RSC ADVANCES LA English DT Article ID NANOSTRUCTURES; NANOFIBERS; NANOWIRES AB We report an easy and simple approach for making silver nanotubes (NTs) using electrospinning. Silver nanoparticles were first deposited on an electrospun polymer nanofiber template by dip-coating in aqueous medium. Subsequently, selective dissolution of the polymer core led to the formation of silver NTs. Average diameter of the NTs was 250 nm and wall thickness was about 50 nm. This method allows the synthesis of a large quantity of silver NTs with high yield. Wall thickness and porosity of the NTs could be readily tuned by varying the dipping time and concentration of the metal precursor. The approach developed is very general and could be used for fabricating NTs of a variety of noble metals, bi-metals and metal oxides.

The use of compost as soil amendment is a universal practice well known for its benefits to soil properties and plant growth. This study aimed to assess the possible benefits of compost addition on the growth parameters of four switchgrass populations, the octaploids Shelter, Shawnee and Dacotah, and the tetraploid Alamo, in pot experiments. Three growing media were prepared by mixing peat (P) with each of three different composts, a green compost (GC), a mixed compost (MC) and a coffee compost (CC), at the percentages of 5%, 10% and 20% (v/v). Results obtained showed that, with respect to the use of P only, all compost mixtures exerted positive effects on root, shoot and primary leaf lengths and on the fresh weight of the different switchgrass populations. In particular, GC/P and MC/P mixtures appeared more efficient at 5% and 10% of compost, whereas CC/P mixtures produced the best results at 10% and 20% of compost. The effects of composts were more evident for the Shawnee population and less for the Shelter one, thus indicating an involvement of the genotype in the plant response.

The Passive Fuel Cell SO JOURNAL OF THE ELECTROCHEMICAL SOCIETY LA English DT Article ID ANION-EXCHANGE MEMBRANE; GAS-DIFFUSION LAYERS; TRANSPORT-PROPERTIES; ALKALINE ELECTRODES; CARBON-DIOXIDE; PTRU CATALYSTS; PERFORMANCE; MODEL; MEDIA; OXIDATION AB The bi-cell, or pseudo-bipolar electrode, configuration provides a compact cell design that is well suited for small and portable fuel cell systems. This format places two membrane electrode assemblies (MBAs) within a unit. The MEAs' anodes are mirrored around a common fuel reservoir, or channel, with the anode of the first MEA electrically connected to the cathode of the second. A hybrid bi-cell format using a first acidic proton exchange membrane (PEM) based MEA and a second alkaline anion exchange membrane (AEM) based MEA is put forth. In this scenario, the respective anodes balance faradaic water requirements. A computational approach is used to explore transport in passive direct methanol bi-cell units, which are fueled from a fixed internal reservoir. The merit of the hybrid hi-cell approach is examined by comparing to a passive standard bi-cell.unit configuration using two PEM based MEAs. Relative to the standard bi-cell, our model shows that the balanced water stoichiometry of the acidic and alkaline methanol oxidations reactions in the hybrid bi-cell reduces the overall rate/volume of water loss from the fuel reservoir during discharge. This benefit is exploited in our complementary manuscript [K. N. Grew and D. Chu, J. Electrochem. Soc., Accepted for publication]. (c) 2014 The Electrochemical Society. All rights reserved.

Concentrated methanol is typically carried as a DMFC fuel source and fed to an internal reservoir, which maintains a dilute fuel mixture feeding the fuel cell stack. Active water and fuel management are required to maintain the concentration and volume of this internal reservoir. Water produced and/or carried to the cathode is condensed and recycled to the anode, requiring a radiator and other components. These components are largely responsible for the size and mass of portable DMFCs. A hybrid hi-cell stack approach is put forth here, which reduces the need for active water and fuel management. This configuration combines membrane electrode assemblies (MEAs) made of proton exchange membrane (PEM) and anion exchange membrane (AEM) electrolytes within individual hi-cell units. The water stoichiometry of the electrochemical oxidation and reduction reactions are complementary for the acidic PEM and alkaline AEM MEAs. A transport model is used to show that standard PEM hi-cell stacks have about 4x the demand for active water recycling that hybrid bi-cell stacks do at typical operating conditions. Opportunities to completely eliminate the need for water recycling are shown. (c) 2014 The Electrochemical Society. All rights reserved.

TI Risk Factors for Disability Retirement Among Active Duty Air Force Personnel SO MILITARY MEDICINE LA English DT Article ID US ARMY; PHYSICAL-FITNESS; MILITARY; INJURY; DISCHARGE; HEALTH; EPIDEMIOLOGY; PREVENTION; PREDICTORS; ATTRITION AB Objective: To determine risk factors for disability retirement in Air Force personnel, as well as the conditions contributing to disability retirement. Methods: A matched case-control study was conducted. Air Force personnel with accession records who were disability retired between 2002 and 2011 were included as cases. Controls were matched by accession year from the population of accessions not evaluated for disability at a ratio of 2:1. Conditional logistic regression was used to determine the odds of disability retirement. Results: Women and those aged 25 or older were significantly more likely to be disability retired. Deployment was also associated with disability retirement but was significantly protective. Among women, the odds of disability retirement did not vary when stratified by deployment history. Preexisting medical conditions were not associated with disability retirement. Psychiatric conditions were the most common condition type among those who were disability retired in the Air Force. Conclusions: Additional studies are needed to assess risk factors for psychiatric disability, the most common disability retired condition, as well as to describe the role of occupation and combat exposure in disability retirement from the Air Force.

TI Lower Extremity Biomechanical Changes Associated With Symmetrical Torso Loading During Simulated Marching SO MILITARY MEDICINE LA English DT Article ID TREADMILL WALKING; LOWER-LIMB; CARRIAGE; KINEMATICS; GAIT; MASS; PARAMETERS AB The dose response relationship between biomechanical variables and the magnitude of external loads is unclear. The use of different load distributions (e.g., pack types) may confound results because of changes in torso center of mass. Therefore, we examined the relationship between load magnitude and sagittal plane lower extremity mechanics of Soldiers walking with two symmetrically distributed loads. Fourteen Soldiers marched on a force-sensing treadmill at 1.34 m/s for 10 minutes with no load (BW_00) and while wearing vest-borne loads of 15 kg (BW_15) and 55 kg (BW_55). The effects of the loads on sagittal plane joint angles and moments were compared using 1-way repeated measures analyses of variance. Compared with BW_00, knee extension moment increased with the 15- and the 55-kg loads (both p < 0.003), confirming previously reported load-related biomechanical responses. Knee moment increases during early stance appeared to be the primary means by which the lower extremity counteracted BW_15 during early stance; in contrast, hip extensors and ankle dorsiflexors appeared to be the primary muscular efforts responsible for propulsion during late stance. Findings elucidated the effects of load magnitude on lower extremity mechanics without postural changes that result from pack-related shifts in torso center of mass.

High FFP:RBC ratio was associated with improved survival compared to low ratio in the EXPL group (p < 0.01). The GSW group had similar survival in the high and low FFP:RBC ratio groups (p = 0.06). After propensity matching, a high FFP:RBC ratio was associated with improved survival compared to low ratio in both the EXPL (p < 0.01) and GSW groups (p = 0.05). Conclusions: High FFP:RBC ratios are associated with improved survival in combat casualties regardless of injury mechanism.

There is a question whether IO-administered epinephrine is equivalent to intravenously administered epinephrine during CA. Methods: The question guiding this evidence-based review was as follows: in adults suffering CA given epinephrine via the IO route, what is the resulting serum concentration of the drug compared to when administered intravenously? A search was conducted and the evidence appraised and leveled. Results: Four animal studies met the inclusion criteria. The sources showed no definitive evidence supporting equivalence between intravenous and IO epinephrine administered during CA. Intravenously administered epinephrine provides increased and faster appearing serum concentrations than IO-administered epinephrine. Evidence indicated epinephrine given via the sternal IO route more closely approaches equivalence with intravenously administered epinephrine than when administered by the tibial IO route. Conclusions: The clinician should consider using proximal IO infusion sites such as the sternum or humerus when administering advanced cardiac life support drugs to rapidly achieve maximal therapeutic concentrations. Further studies are needed to determine the differences seen when epinephrine is administered by these routes during CA.

Here, we investigate the ability of the suggested molecular mechanisms to account for fibrin generation and degradation kinetics in diverse, physiologically relevant in vitro systems. We represented the protein interaction network responsible for thrombin generation, fibrin formation, and fibrinolysis as a computational kinetic model and benchmarked it against published and newly generated data reflecting diverse experimental conditions. We then applied the model to investigate the ability of fibrinogen and a recently proposed prothrombin complex concentrate composition, PCC-AT (a combination of the clotting factors II, IX, X, and antithrombin), to restore normal thrombin and fibrin generation in diluted plasma. The kinetic model captured essential features of empirically detected effects of prothrombin, fibrinogen, and thrombin-activatable fibrinolysis inhibitor titrations on fibrin formation and degradation kinetics. Moreover, the model qualitatively predicted the impact of tissue factor and tPA/tenecteplase level variations on the fibrin output. In the majority of considered cases, PCC-AT combined with fibrinogen accurately approximated both normal thrombin and fibrin generation in diluted plasma, which could not be accomplished by fibrinogen or PCC-AT acting alone. We conclude that a common network of protein interactions can account for key kinetic features characterizing fibrin accumulation and degradation in human blood plasma under diverse experimental conditions. Combined PCC-AT/fibrinogen supplementation is a promising strategy to reverse the deleterious effects of dilution-induced coagulopathy associated with traumatic bleeding.

This paper develops optimization models and heuristics to maximize the benefits of the maintenance projects selected for funding in a multimodal transportation network. This paper includes a mixed linear integer model to maximize the overall network capacity while allowing for partial funding of each project. The model is further extended to account for the random nature of shoaling and subsequent vessel draft restrictions after dredging to maximize the expected capacity over a multiyear study period. In addition, two heuristics are proposed to provide approximate solutions efficiently. All the models and heuristics are tested on real network examples.

For K the boundary of a bounded open set in R-N, this is the space to which the boundary functions for the Dirichlet problem belong. The space of polynomials of degree less than or equal to m, and the subspace of polynomials homogeneous of degree k, are finite dimensional spaces discussed here and which are used in the approximate solution of the Dirichlet problem. The Hahn-Banach Theorem is proved, and is a key ingredient in proving that the complex variable boundary element method will provide approximate solutions to the Dirichlet problem.

Certainly detecting trace levels of threat agents against a complex background is chief among these challenges; however, the related issues of multiple target distances (from standoff to proximity) and sampling time scales (from passive mines to rapid rate of march convoy protection) for different applications make it unlikely that a single technique will be ideal for all sensing situations. A number of methods for spanning the range of optical sensor technologies exist which, when integrated, could produce a fused sensor system possessing a high level of sensitivity to threat agents and a moderate standoff real-time capability appropriate for portal screening of personnel or vehicles. In this work, we focus on several promising, and potentially synergistic, laser-based methods for sensing threat agents. For each method, we have briefly outlined the technique and report on the current level of capability. C1 [Johnson, J.

Using a standardized battery of tests, an artificial neural network was used to create an algorithm to perform pattern analysis matching (PAM) functions that can be used to assist with diagnosis. PAM analyzes a patient's neuropsychological data and provides a best fit classification, according to one of four groups: TBI, PTSD, malingering/invalid data, or "other'' (depressed/anxious/postconcussion syndrome/normal). The original PAM was modeled on civilian data; the current study was undertaken using a database of 100 active-duty army service personnel who were referred for neuropsychological assessment in a military TBI clinic. The PAM classifications showed 90% overall accuracy when compared with clinicians' diagnoses. The PAM function is able to classify detailed neuropsychological profiles from a military population with a high degree of accuracy and is able to distinguish between TBI, PTSD, malingering/invalid data, or "other.'' PAM is a useful tool to help with clinical decision-making. C1 [Meyers, John E.] Concuss Clin, Schofield Barracks, HI 96857 USA. [Miller, Ronald M.; Tuita, Alexa R.

The preparation of CNTs coated with magnetically sensitive Fe2O3 nanoparticles has implications to the development of advanced heat transfer nanofluids and high capacity lithium ion batteries. In this paper, various characterization methods confirm that single-walled carbon nanotubes (SWNTs) were uniformly coated with Fe2O3 nanoparticles through solution mixture. Scanning and transmission electron microscopy were used to compare the morphology of pristine SWNTs and as-prepared SWNTs coated with Fe2O3 nanoparticles. Raman spectroscopy and thermo gravimetric analysis presented the extent of defects and the amount of Fe2O3 nanoparticles present in the sample.

TI Assessment of Subyearling Chinook Salmon Survival through the Federal Hydropower Projects in the Main-Stem Columbia River SO NORTH AMERICAN JOURNAL OF FISHERIES MANAGEMENT LA English DT Article ID ACOUSTIC TELEMETRY SYSTEM; WATER-RESOURCES; CLIMATE-CHANGE; JUVENILE; TRANSMITTERS; PERFORMANCE; TRACKING; BASIN AB High survival through hydropower projects is an essential element in the recovery of Pacific salmon Oncorhynchus spp. populations in the Columbia River. High dam passage survival is also a regulatory requirement under the 2008 Biological Opinion (BiOp; established under the Endangered Species Act) on Federal Columbia River Power System operation. The BiOp requires dam passage survival to be at least 0.96 and at least 0.93 for spring and summer out-migrating juvenile salmonids, respectively, and to be estimated with an SE of 0.015 or lower. An innovative virtual/paired-release design was used to estimate dam passage survival, which was defined as survival from the upstream face of a dam to the tailrace mixing zone. A coordinated four-dam study was conducted during the 2012 summer out-migration using 14,026 subyearling Chinook Salmon O. tshawytscha out-migrants with surgically implanted acoustic micro-transmitter tags. The release-recapture design consisted of 9 different release locations and 14 different detection arrays. Each of the four estimates of dam passage survival exceeded BiOp requirements, with values ranging from 0.9414 to 0.9747 (SE = 0.0031-0.0114). The virtual/paired-release design illustrated here has potential applicability wherever dam passage survival of migrant juvenile fish stocks must be estimated.

TI Long-Term Population Response of Triploid Grass Carp Stocked in Piedmont and Coastal Plain Reservoirs to Control Hydrilla SO NORTH AMERICAN JOURNAL OF FISHERIES MANAGEMENT LA English DT Article ID SANTEE-COOPER RESERVOIRS; SOUTH-CAROLINA; MANAGEMENT; IMPACTS; GROWTH AB The triploid Grass Carp Ctenopharyngodon idella has been used to control hydrilla Hydrilla verticillata infestations in southern U. S. reservoirs for several decades. After eliminating hydrilla in the water column, Grass Carp must be maintained in sufficient densities to control hydrilla regrowth from the tuber banks in the hydrosoil. We monitored the long-term response of triploid Grass Carp populations that had eliminated hydrilla within the water column in two Piedmont (Lake Norman and Mountain Island Lake, North Carolina) and two Coastal Plain reservoirs (the Santee Cooper system comprising Lakes Marion and Moultrie, as well as the connecting canal in South Carolina). Triploid Grass Carp stocked in Lake Norman and Mountain Island Lake exhibited both slow growth and erratic, but potentially high, mortality. Due to erratic survival in the two Piedmont reservoirs, we could not estimate mortality using a catch curve. Fish stocked into the Santee Cooper system not only grew larger and faster, they also persisted (i.e., significant numbers of age-16-21 fish were collected during sampling in 2011). We hypothesize that Piedmont reservoirs without hydrilla in the water column and with little naturally occurring aquatic vegetation have a very low carrying capacity for triploid Grass Carp. Consistent, long-term survival of triploid Grass Carp in the Santee Cooper system may be due to available food provided by hydrilla regrowth in the water column, floating vegetation, and less-palatable, native, submersed vegetation. Hydrilla management in systems with residual plant food could involve estimating an average mortality rate and maintaining enough fish (i.e., about one fish per four hectares of surface area) to control hydrilla regrowth. In Piedmont reservoirs, possible management alternatives could include maintenance stockings based upon (1) yearling stocking rates that were successful in the past, (2) stockings determined from indirect measures of mortality such as from von Bertalanffy growth equation parameters, or (3) stockings derived from measures or indices of abundance such as counts conducted at night by bowfishers.

The MS-222 exposure effects and appropriate exposure times for juvenile Chinook Salmon undergoing intracoelomic implantation were determined using blood analytes (Na+, K+, Ca2+), blood pH, plasma cortisol, and survival immediately following anesthetic exposure (3, 6, 9, and 12 min on day 0) and over a recovery period (days 1, 7, and 14). In addition, effects were examined in surgically implanted and nonimplanted fish (but exposed to MS-222 for 3 min) over a 14-d recovery period. Regardless of anesthetic exposure time, there were no mortalities during exposure on day 0 or over the recovery period. On day 0, MS-222 exposure treatments of 9 and 12 min resulted in significantly higherNa(+) and Ca2+ and lower K+, indicating a reduced ability to maintain osmotic balance; however, MS-222 effectively dampened the cortisol release following surgical implantation and anesthetic exposure. Cortisol concentration was significantly higher in surgically implanted fish than in those not surgically implanted over the recovery period. Given these results, we recommend MS-222 exposure (80 mg/L) times of 6 min or less for compliance programs and studies involving age-1 Chinook Salmon. In addition, we recommend for other monitoring programs, regardless of species, that maximum MS-222 exposure times are implemented to minimize stress and surgical effect and that exposure times are specific to a species' life stage to prevent overexposure and long-term effects. Furthermore, the knowledge of effects and the development of maximum exposure times are beneficial for hatchery programs, fish barging or transportation programs, and most studies in which fish behavior and physiological responses would need to be dampened using MS-222 without adverse side effects.

Four performance tests, intended to screen for rutting susceptibility, were performed on 26 hot mix asphalt (HMA) mixtures using one neat binder. Eight of these mixtures were also prepared with a polymer-modified binder. Results from four candidate tests are presented: asphalt pavement analyzer, triaxial creep, triaxial repeated load, and dynamic modulus test. Preliminary criteria associated with these tests that can be used to screen or select airport HMA paving mixtures are proposed. The efficacy of the screening tests and associated criteria were evaluated by constructing and trafficking full-scale pavements using an accelerated pavement tester.

(And it is shown that if f is a polynomial, the result is false.) The proof uses the Hahn-Banach Theorem. If the function f is taken to have a power series convergent about zero, the solution, harmonic in D and approximating g on the boundary, is the real part of a finite sum of terms of the form c(n)(f (a(n)(z + b(n))). In applications the real parameters a(n), b(n), c(n), n = 1, 2,..., M are obtained by computer minimization of the error of the fit to the given function g on the boundary of the domain. The proof depends on the Walsh-Lebesgue Theorem, which is shown to be equivalent to the complex variable approximate boundary value result as stated in this chapter. Note that the approximation is to the boundary function g on the boundary of the domain, the approximating functions satisfy the Laplace equation exactly in D C1 [Hromadka, Theodore] US Mil Acad, West Point, NY 10996 USA.

The Dirichlet problem is to find such a function of N variables, satisfying the Laplace equation in the interior of a domain D and being equal to a given continuous complex-valued function g on the boundary Gamma of D. The case of interest in applications is N=3, but there is no essential difference in considering general N. In addition to specifying that the bounded open set D not have any holes, bubbles in three dimensions, which was enough in two dimensions, additional conditions are necessary in three or higher dimensions, and the relevant Poincare condition is discussed. The proof uses the Hahn-Banach Theorem applied in the space C(K) of complex-valued continuous functions defined on the boundary K of the domain. In the final result it is shown that there is an approximate solution using any one chosen function f (z), which is not a polynomial and which has a power series convergent (about z = 0). This approximate solution is a finite sum of the form c(n) f (a((n)) . x + b(n) . x + d(n)) where c(n) and d(n) are complex numbers, a((n)) and bn are vectors in RN with the same length, ||a((n))|| = ||b((n))||, which are perpendicular a((n)) . b(n) = 0, and x is a point in R-N. The proof relies on a lemma which shows how to construct a harmonic function in N variables from a harmonic function in two variables, which will be applied to the real and imaginary parts of f (z), and a representation theorem for the space of harmonic polynomials in N-variables which are homogeneous of degree m.

The purposes were not just to save lives, but to benefit the military by returning more patients to duty and reducing the size of the hospital system through fewer infections and shorter hospital stays. The Army examined the utility of the units at the end of the war and retained them for any future conflicts, but opposition also survived. The question was the utility for the Army: was it worth making a substantial investment, and reducing care for other wounded soldiers, for the most grievously wounded, perhaps 1 percent of the total? Devising an effective way to organize forward SHs was a problem in the interwar years and early in World War II (WWII). But from the late 1930s, the Army never reexamined whether it should provide forward surgery, only how to do so, including pushing surgeons even further forward on the battlefield. At the end of WWII, the Mobile Army Surgical Hospital (MASH) was created to perform the mission, although the MASH was only the latest format.

The devices, based on elastomeric polymers and shear thickening fluids, exhibit low resistance to extension at rates below 10 mm/s, but when stretched at 100 mm/s or higher resist with up to 7x. higher force. A link between the shear thickening fluid's rheology and the dynamic ligament's tensile performance is presented to explain the rate-dependent response. Future recommendations for improving device performance are presented, along with a host of different potential application areas including safety equipment, adaptive braces, sporting goods, and military equipment.

The device consists of a polycrystalline galfenol (Fe-Ga alloy) strip bonded to a brass cantilever beam. Two brass pieces, each containing a permanent magnet, are used to mass load each end of the beam and to provide a magnetic bias field through the galfenol strip. The voltage induced in an induction coil closely wound around the cantilever beam captures the time rate of change of magnetic flux within the galfenol strip as the beam vibrates. The first bending-mode resonant frequency of the device was 69.42 Hz. To dissipate the electrical voltage from the device, a shunt circuit is attached. The effective mechanical impedance for the magnetostrictive shunt circuit is derived. The shunted model is specialized for two shunt circuits: the case of a resistor and that of a capacitance. The experimental results for both the resistive and capacitance shunt circuits validate the shunted magnetostrictive damping model for couple of cased of resistance and capacitance.

TI Polyhedra faster than spheres? SO ENGINEERING COMPUTATIONS LA English DT Article DE DEM; Discrete element modelling; Polyhedral grains ID DISCRETE ELEMENT METHOD; MODEL AB Purpose - The purpose of this paper is to present a new and efficient technique for discrete element modelling using non-convex polyhedral grain shapes. Design/methodology/approach - The efficiency of the technique follows from the use of grains that are dilated versions of the basic polyhedral grain shapes. Dilation of an arbitrary polyhedral grain is accomplished by placing the center of a sphere of fixed radius at every point on the surface. The dilated vertices become sphere segments and the edges become cylinder segments. The sharpness of the vertices and edges can be adjusted by varying the dilation radius. Contacts between two dilated polyhedral grains can be grouped into three categories; vertex on surface, vertex on edge, and edge on edge, or in the grammar of the model, sphere on polygonal surface, sphere on cylinder, and cylinder on cylinder. Simple, closed-form solutions exist for each of these cases. Findings - The speed of the proposed polyhedral discrete element model is compared to similar models using spherical and ellipsoidal grains. The polyhedral code is found to run about 40 percent as fast as an equivalent code using spherical grains and about 80 percent as fast as an equivalent code using ellipsoidal grains. Finally, several applications of the polyhedral model are illustrated. Originality/value - Few examples of discrete element modeling studies in the literature use polyhedral grains. This dearth is because of the perceived complexity of the polyhedral coding challenges and the slow speed of the codes compared to codes for other grain shapes. This paper presents a much simpler approach to discrete element modeling using polyhedral grain shapes. C1 US Army, Cold Reg Res & Engn Lab, Hanover, NH 03755 USA.

LNMO-based cells, however, tend to suffer from capacity fading due to transition metal dissolution that is exacerbated by increased temperatures. In this study, the electrolyte additives LiDFOB, HFiP, FEC and combinations of the three were investigated to determine which additives are able to properly passivate the LNMO surface to hinder Ni and Mn dissolution and thus enable high temperature cycling with a reduced fade rate. A combination of FEC and HFiP additives yielded the best high temperature performance with a Coulombic efficiency >97% and a decreased electrolyte decomposition above 4.8 V.

Many students realized modest to moderate improvement in performance on homework assignments and exams by using the videos as a review. Based on student feedback and access patterns, the videos are shown to serve as a valuable supplement (but not a replacement) for traditional in-classroom instruction.

What is less clear is how these advances translate into functional benefits for the user with amputation. Study aims were to (1) quantify outcomes including dexterity, performance of daily activities, and prosthetic skill and spontaneity of users of the DEKA Arm and (2) compare outcomes when using the DEKA Arm with scores using the existing prosthesis. This was a quasi-experimental study. Descriptive analyses examined outcomes by DEKA Arm configuration level. Of the 39 subjects fit with a DEKA Arm, 32 were trained in use and completed end-of-study testing. Data from 26 prosthetic users were used to compare outcomes using existing prostheses with outcomes with the DEKA Arm. Dexterity and activity performance with the DEKA Arm varied by amputation level (p < 0.01). Self-reported function and number of activities performed using the prosthesis were similar across levels. Comparisons with existing prostheses showed the effect on dexterity varied by level. Activity performance and spontaneity of prosthetic use improved for users of the shoulder configuration level, while use of the prosthesis to perform activities and perceived difficulty performing self-selected tasks improved for all levels.

The p-n(-) SiC- metal diodes, employing a transparent window metal, have a nearly flat response between 200-270 nm with peak external quantum efficiency (EQE) of 45%. A peak QE of 76% is observed for the p-n(-) SiC - n-AlxGa1-xN diodes at 242 nm. The significant enhancement in short wavelength response observed in both diodes is attributed to preferential absorption of deep ultraviolet photons within the depletion region of these structures as compared to that in the top doped layer of a p-i-n SiC photodiode, and the more efficient collection of photo-generated carriers through drift despite the presence of surface/interface states.

Plasmonic sensor research has contributed to chemical and biological sensing needs by monitoring ultrafast temporal and spatial changes in optoelectronic systems. Nonlinear plasmonic waveguides with subwavelength confinement can further enhance the capabilities of plasmonic devices. Results in this paper highlight the derivation of the full-vector Maxwell Equations for the single metal-dielectric slot waveguide and the metal - dielectric - metal waveguide with the dielectric having a Kerr-like nonlinearity. These waveguides, typically have metallic losses that compete with nonlinearity at certain frequencies that can hinder surface plasmon wave propagation. By considering temporal and spatial beam propagation in these waveguides one expects to observe novel effects that could be used for sensing applications such as femtosecond pulse propagation with plasmon self-focusing, self-trapping, and frequency conversion with reduction in metallic losses.

Metamaterials made of two and three dimensional lattices of periodically placed electromagnetic resonant cells can achieve absorption and propagation of incident electromagnetic radiation as confined electromagnetic fields confined to a waveguide as surface plasmon polaritons, which can be used for shielding an object from in-tune electromagnetic radiation. The periodicity and dimensions of resonant cavity determine the frequency, which are very small as compared to the wavelength of incident light. Till now the phenomena have been demonstrated only for lights in near infrared spectrum. Recent advancements in fabrication techniques have made it possible to fabricate array of three dimensional nanostructures with cross-sections as small as 25 nm that are required for negative refractive index for wavelengths in visible light spectrum of 400-700 nm and for wider view angle. Two types of metamaterial designs, three dimensional concentric split ring and fishnet, are considered. Three dimensional structures consisted of metal-dielectric-metal stacks. The metal is silver and dielectric is yttrium oxide, other than conventional materials such as FR4 and Duroid. High. dielectric and high refractive index as well as large crystal symmetry of Yttrium oxide has been investigated as encapsulating medium. Dependence of refractive index on wavelength and bandwidth of negative refractive index region are analyzed for application towards cloaking from light in visible spectrum.

Cold sprayed Ni+Al and explosively compacted mixtures of Ni+Al+W and Ni+Al+W+Zr powders were fabricated into ring shaped samples and explosively fragmented. Ring velocity was monitored and fragments were soft captured in order to study the fragmentation process. It was determined that the fragments produced by these structural energetic materials are much smaller than those typically produced by ductile metals such as steel or aluminum. This has implications for combustion processes that may occur subsequent to the fragmentation process.

IR and Raman spectra of amorphous p-CO, calculated at 5.02 GPa from the dielectric tensor, are presented and show significant contributions of intact CO molecules, CO fragments decorating chains, and lactones of amorphous p-CO structures. DFT simulations of formation of amorphous polymeric structures were also done with the addition (as a result of replacement of CO molecules) of N or He atoms to the crystalline delta phase of CO. For the CO-N mixtures, the concentration of N was varied in the range from 6.25 % to 50% with different distribution patterns of N atoms in the unit cell. For all studied CO-N concentrations, isotropic compression led to CO polymerization beginning at a pressure of 11 GPa; the N was not incorporated in significant numbers (up to pressures of 20 GPa) in the random p-CO which starts to polymerize. This transition pressure is higher than that for pure p-CO to start to polymerize at 8 GPa. For the CO-He mixtures, the concentration of He atoms in the delta phase of CO was 12.5% of the number of atoms. Formation of random networks begins at 9 GPa and at 11 GPa all CO molecules have formed a combination of closed rings and chain type structures without any isolated CO molecules with a density of 2.40 g/cm(3). He atoms appear to facilitate complete formation of the random structure at a lower pressure than that for pure poly-CO, which is almost completely polymerized at a pressure of 18 GPa. He atoms also help stabilize the structure while lowering the pressure down to 100 Bar with only few CO molecules detaching in the process. Without He atoms at the same pressure there are approximately ten times the number CO molecules occupying voids in the random network. C1 [Batyrev, I. G.; Mattson, W.

The single-crystal HSRVP model tracks the nucleation, multiplication, annihilation, and trapping of dislocations, as well as thermally activated and phonon drag limited glide kinetics. The steady plastic wave formulation is used to model the elastic-plastic response with respect to a propagating longitudinal wave, and assumes that the magnitudes of quasi-transverse waves are negligible. This steady wave analysis does not require specification of artificial viscosity, which can give rise to spurious dissipative effects. The constitutive model and its numerical implementation are applied to single-crystal pure Al and results are compared with existing experimental data. Dislocation density evolution, lattice reorientation, and macroscopic velocity-time histories are tracked for different initial orientations subjected to varying peak shock pressures. Results suggest that initial material orientation can significantly influence microstructure evolution, which can be captured using the modified Taylor factor. C1 [Lloyd, J. T.; McDowell, D.

The evolution of the spectra over the first 300 ps was recorded in each case. All spectra show monotonic decay of all peaks with increasing time after shock. No new peaks due to either chemical reaction or pressure shifting of the vibrational frequencies were observable. This loss of signal after shock is attributed to the decreased coherence time in the shock heated liquids, which leads to rapid signal loss in the nonresonant background free version of CARS used in the measurements. These results suggest that more complex methods may be required to measure picosecond shock induced chemistry with coherent Raman techniques that are free of nonresonant background interference.

The symmetrical impact of an RDX impactor and target plates with 1 m diameter spheres is simulated at planar impact velocities of 208 m/s and 876 m/s with a Lennard-Jones-like potential, dissipative, and random forces, and artificial viscosity force between particles. The in situ shock quantities were obtained using Hardy's averaging. In situ longitudinal stresses from simulations were 0.84 and 3.82 GPa. Values from the literature are 0.81 and 2.92 GPa at the two impact velocities, respectively. The uniaxial strain condition was predicted with equal lateral stresses and negligible shear stresses. The higher stress value at 876 m/s may be due to lack of inelasticity in the interparticle potential. The temperature increases of 5.5 K-0 and 93.7 K-0, respectively, were predicted assuming dissipation of a fraction of the potential energy. It is concluded that the DPDE method holds promise for a unified computational framework for multi-scale simulations of HE.

Available experimental thermodynamic properties and Hugoniot values have been analyzed to establish the equations of state for the carbon phases. The diamond-graphite transition curve results from the equality of the chemical potentials of the phases. The resulting relationships are utilized to examine the actual phase behaviour of carbon under shock conditions. The existence of metastable carbon states is established by analyses of Hugoniot data for hydrocarbons and explosives at elevated temperatures and pressures. The accuracy of the resulting relationships is demonstrated by comparisons for several properties, including the Hugoniot behaviour of oxygen-deficient explosives at overdriven conditions.

Al 5083 is a light-weight and strain-hardenable aluminum alloy used for armor plating in military transport vehicles, thus requiring the highest achievable spall strength and HEL. Materials that were processed by ECAP displayed a highly refined grain structure with little texture and a large degree of plastic deformation, whereas subsequent rolling resulted in a textured microstructure with both grains and inclusions aligning along the rolling direction. The spall behavior of Al 5083 was determined using plate-impact gas-gun experiments with rear free surface velocity measurements for a variety of processing conditions involving both ECAP and rolling. The spall strength and HEL increased from that of the as-received material after processing with ECAP. Subsequent rolling further increased the HEL but reduced the spall strength. Rolling also resulted in directional dependence of the spall strength, with the lowest spall strength occurring for impact through the plate thickness and highest spall strength in the rolling direction. The trends in the spall behavior correlate with the size and preferential alignment of manganese dispersoids and iron and silicon rich inclusions that are evolved during processing. C1 [Whelchel, R.

Seventy specimens collected between 2001 and 2010 (99%: 2006-2010) were dissected and gut contents analyzed. The macrohabitats and habits associated with sturgeon prey items (primarily benthic macroinvertebrates) were used to make inferences about habitat use by young-of-year river sturgeon. These findings indicate that young river sturgeon inhabiting the Lower Mississippi River feed primarily over sandy benthos, most likely in channel habitats. The majority of prey items (64.0%) consumed by young-of-year river sturgeon belong to a single subgroup of Chironomidae (Diptera: Chironominae: Harnischia complex) of which several genera, including Chernovskiia, Cryptochironomus, Gillotia, Paracladopelma, Robackia, and Saetheria, are known to be primary inhabitants of this macrohabitat.

TI Use of Automated Radio Telemetry to Detect Nesting Activity in Ornate Box Turtles, Terrapene Ornata SO AMERICAN MIDLAND NATURALIST LA English DT Article ID WINTER ACTIVITY PATTERNS; LONG-LIVED ORGANISMS; NORTHWESTERN ILLINOIS; EMYDOIDEA-BLANDINGII; LIFE-HISTORY; MUD TURTLE; CONSERVATION; POPULATION; MANAGEMENT; DEMOGRAPHY AB Researchers often employ radio telemetry to locate study animals efficiently, but the time required to locate individuals can make monitoring large populations difficult and costly. In 2010-2011 we located nesting ornate box turtles (Terrapene ornata) in a large group of radio-tagged animals. To minimize search efforts, we investigated whether automated radio telemetry and the signal change method could be used to identify nesting activity before locating animals. The signal change method relies on the principle that any movement of a radio transmitter, including minor changes in orientation, can strongly affect the intensity of the transmitter's signal at a stationary receiving station. Using video recordings of free-ranging radio-tagged turtles, we confirmed that transmitter signal strength values can be analyzed to identify periods of box turtle activity. Early in the 2010 nesting season, automated telemetry observations indicated that some females engaged in nocturnal activity. Previous reports indicate that ornate box turtles often nest at night but are otherwise inactive after dark. Based upon this information and relatively little indication of nocturnal activity by males, we hypothesized that nocturnal activity corresponded to nesting. We subsequently monitored female nighttime activity in near real time, hand-tracked four night-active individuals, and found three of these turtles nesting. In 2011 we again selectively hand-tracked night-active females and located nests for 12 of 18 study animals, which approximates the expected annual reproductive rate for our population. We demonstrate that the signal change method can be used to identify nesting activity in ornate box turtles and suggest this method may be of use in other species that nest outside of their normal activity periods.

The combination of mercury cadmium telluride detectors and Fabry Perot filters (FPFs) is highly desirable for hyperspectral detection over a broad wavelength range. The geometries of distributed Bragg reflector (DBR)-based tunable FPFs are modeled to achieve a desired spectral resolution and wavelength range. Additionally, acceptable fabrication tolerances are determined by modeling the spectral performance of the FPFs as a function of DBR surface roughness and membrane curvature. These fabrication nonidealities are then mitigated by developing an optimized DBR process flow yielding high-performance FPF cavities suitable for integration with hyperspectral imagers.

TI Fabrication of resonator-quantum well infrared photodetector test devices SO JOURNAL OF MICRO-NANOLITHOGRAPHY MEMS AND MOEMS LA English DT Article DE inductively coupled plasma etching; resonator-quantum well infrared photodetectors focal plane array; GaAs substrate removal ID DAMAGE; GAAS; INP AB An optimized detector fabrication process is developed for resonator-quantum well infrared photodetectors (R-QWIPs). The R-QWIPs are the next generation of QWIP detectors that use resonances to increase the quantum efficiency (QE). To achieve the expected performance, the detector geometry must be produced in precise specification. In particular, the height of the diffractive elements and the thickness of the active resonator must be uniformly and accurately realized to within 0.05-mu m accuracy. To achieve this specification, an optimized inductively coupled plasma etching process with a nearly infinite etching selectivity for the GaAs over the AlxGa1-xAs etch-stop layer was developed. Using this etching technique, we have fabricated a number of R-QWIP test detectors with the required dimensions. Their QE spectra were tested to be in close agreement with the QE predictions.

TI An Event History Analysis of First-Term Soldier Attrition SO MILITARY PSYCHOLOGY LA English DT Article DE US military; attrition; attitudes; confidence in term completion; ambivalence ID PLANNED BEHAVIOR; ATTITUDES; TURNOVER; FORCE; NAVY AB The study of attrition has largely focused on identifying demographic or biographic characteristics that predict whether soldiers complete their enlistment term. As a result, much is known about who attrites. Less is known about why soldiers attrite. This research assessed the influence of two psychological factors on U. S. Army soldier attrition: self-reported confidence that one could complete one's term of service and ambivalence regarding the decision to enlist. The study sample consisted of first-term enlisted soldiers (N = 14,808) who were respondents to Army surveys. Results of fitting three longitudinal models indicated that confidence in being able to complete one's term of obligation was more predictive of attrition for those reporting greater ambivalence regarding the decision to enlist. This effect was significant throughout a 3-year period. This work adds to our understanding of attrition by highlighting the role of confidence and ambivalence. Implications for strategies to reduce attrition are discussed. C1 [Gibson, Jennifer Lee] US Army Res Inst, Consortium Res Fellows Program, Arlington, VA USA.

Our approach is guided by protein-protein interactions in natural systems and focuses on the heterotrimeric complex of cardiac troponin I (cTnI), C (cTnC) and T (cTnT). A key premise of this work is that cTnC and cTnT, owing to their innate ability to bind cTnI, are potential templates for the design and discovery of cTnI-binding peptides. Relying only on the knowledge of primary sequences of cTnC and cTnT, we designed a library of short overlapping peptides that span the entirety of cTnC and cTnT and tested them for binding to cTnI. We were successful in identifying several peptides that display high affinity (1-100 nM) for cTnI. The specific implication of this work is that mimicking natural protein-protein interactions is an excellent starting point for the discovery and rational design of peptide ligands. The knowledge of secondary or tertiary structures of the proteins involved is not a necessary precondition for this approach. Nevertheless, we show that structural information can be used to validate the results of a fragment-based peptide design, and can be potentially beneficial for refining the lead candidates. Our approach is broadly applicable to any protein with at least one natural binding ligand with known primary sequence. For protein targets with multiple natural ligands, this approach can potentially yield several distinct affinity peptides capable of simultaneously binding the target protein via orthogonal modes or at complementary interfaces.

Little is known of the recognition of the vaccine by the host's innate immune system and how it affects the acquired immune response to the vaccine. Thus, we vaccinated Toll-like receptor (Tlr) 2, 4, and 2/4-double deficient, as well as signal adaptor protein Myd88-deficient mice. We found that Tlr4 and Myd88 appeared to be required for an optimal immune response to the F1-V vaccine but not Tlr2 when compared to wild-type mice. However, there was a difference between the requirement for Tlr4 and MyD88 in vaccinated animals. When F1-V vaccinated Tlr4 mutant (lipopolysaccharide tolerant) and Myd88-deficient mice were challenged by aerosol with Y. pestis CO92, all but one Tlr4 mutant mice survived the challenge, but no vaccinated Myd88-deficient mice survived the challenge. Spleens from these latter nonsurviving mice showed that Y. pestis was not cleared from the infected mice.

Social factors, specifically societal-level social capital, play a far more important role in explaining patterns of terrorist activity than previously recognized. Social capital can exert pressures that act as both restraint and catalyst for terrorism, making explicit exposition of these differential effects critical. Analysis shows that higher stocks of social capital positively correlate with the number of terrorist groups, but the average attack activity of those groups increase as measures of social capital decline. The complex relationship makes it difficult to draw simple policy implications, but it does offer insight into the role that social dynamics play in terrorist activity.

Wideband spectrum sensors remain the most challenging block in the software defined radio hardware design. The use of passive switched capacitors provides a very low power signal conditioning front end that enables parallel digitization and software control and cognitive capabilities in the digital domain. In this paper, existing architectures are reviewed followed by a discussion of high speed passive switched capacitor designs. A passive analog FFT front end design is presented as an example analog conditioning circuit. Design methodology, modeling, and optimization techniques are outlined. Measurements are presented demonstrating a 5 GHz broadband front end that consumes only 4 mW power. C1 [Sadhu, Bodhisatwa; Sturm, Martin; Harjani, Ramesh] Univ Minnesota, Minneapolis, MN 55455 USA.

TI Balancing the Rates of New Bone Formation and Polymer Degradation Enhances Healing of Weight-Bearing Allograft/Polyurethane Composites in Rabbit Femoral Defects SO TISSUE ENGINEERING PART A LA English DT Article ID CALCIUM-PHOSPHATE CEMENT; LOCALLY HIGH-CONCENTRATIONS; TIBIAL PLATEAU FRACTURES; TRABECULAR BONE; CANCELLOUS BONE; MORPHOGENETIC PROTEIN-2; MECHANICAL-PROPERTIES; COMPUTED-TOMOGRAPHY; INTERNAL-FIXATION; SHEAR-STRENGTH AB There is a compelling clinical need for bone grafts with initial bone-like mechanical properties that actively remodel for repair of weight-bearing bone defects, such as fractures of the tibial plateau and vertebrae. However, there is a paucity of studies investigating remodeling of weight-bearing bone grafts in preclinical models, and consequently there is limited understanding of the mechanisms by which these grafts remodel in vivo. In this study, we investigated the effects of the rates of new bone formation, matrix resorption, and polymer degradation on healing of settable weight-bearing polyurethane/allograft composites in a rabbit femoral condyle defect model. The grafts induced progressive healing in vivo, as evidenced by an increase in new bone formation, as well as a decrease in residual allograft and polymer from 6 to 12 weeks. However, the mismatch between the rates of autocatalytic polymer degradation and zero-order (independent of time) new bone formation resulted in incomplete healing in the interior of the composite. Augmentation of the grafts with recombinant human bone morphogenetic protein-2 not only increased the rate of new bone formation, but also altered the degradation mechanism of the polymer to approximate a zero-order process. The consequent matching of the rates of new bone formation and polymer degradation resulted in more extensive healing at later time points in all regions of the graft. These observations underscore the importance of balancing the rates of new bone formation and degradation to promote healing of settable weight-bearing bone grafts that maintain bone-like strength, while actively remodeling.

However, while planning and scientific assessments have advanced substantially, successful re-operation of infrastructure to achieve environmental benefits has been more limited. The Sustainable Rivers Project (SRP) was formalized in 2002, as a national partnership between the United States Army Corps of Engineers and The Nature Conservancy to define and implement environmental flows through adaptive reservoir management. The project has focused on eight demonstration basins containing 36 Corps dams, but is designed to direct the collective experience from these sites to help guide agency-wide operational changes for as many as 600 dams to benefit up to 80 000 river kilometres and tens of thousands of hectares of related floodplain and estuarine habitat. This article summarizes the progress to date on defining and implementing environmental flows through the SRP, and evaluates the technical, social, legal, and institutional factors that act as dominant enabling conditions and constraints to implementation.

With the assistance of microbial endosymbionts, termites are responsible for the conversion of complex biopolymers into simple carbon substrates. Termites also rely on endosymbionts for fixing and recycling nitrogen. As a result, we hypothesize that termite bacterial endosymbionts are a novel source of metabolic pathways for the transformation of nitrogen-rich compounds like explosives. Methods: Explosives transformation capability of termite (Reticulitermes flavipes)-derived endosymbionts was determined in media containing the chemical constituents nitrotriazolone (NTO) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) that comprise new insensitive explosive formulations. Media dosed with 40 mu g/ml of explosive was inoculated with surface-sterilized, macerated termites. Bacterial isolates capable of explosives transformation were characterized by 16S rRNA sequencing. Results: Termite-derived enrichment cultures demonstrated degradation activity towards the explosives NTO, RDX, as well as the legacy explosive 2,4,6-trinitrotoluene (TNT). Three isolates with high similarity to the Enterobacteriaceae (Enterobacter, Klebsiella) were able to transform TNT and NTO within 2 days, while isolates with high similarity to Serratia marcescens and Lactococcus lactis were able to transform RDX. Conclusion: Termite endosymbionts harbor a range of metabolic activities and possess unique abilities to transform nitrogen-rich explosives. (C) 2014 S.

Acquisition of resistance genes has proven to be difficult to characterize and is largely uncontrollable in the environment. Here we sought to characterize conjugal horizontal gene transfer of plasmid-encoded fluoroquinolone resistance genes from two strains of Enterobacteriaceae, one clinical and one from a municipal waste-water treatment plant environment. Conjugation was dissimilar between the two strains. Escherichia coli strain LR09, containing a plasmid with the aac(6 ')-lb-cr fluoroquinolone resistance gene, did not conjugate with any of the 15 strains tested, while Enterobacter aerogenes strain YS11 conjugated with two strains of E. coli. The resultant transconjugants were also dissimilar in their stability and potential persistence. The observations presented herein exemplify the difficulties in understanding and controlling the spread of antimicrobial resistance. Thus, it may be prudent to address drug disposal and destruction, incorporating a life-cycle assessment plan 'from cradle to grave', treating antimicrobials as chemical or environmental contaminants.

Many uncertainties remain in our understanding of ODE characteristics, including the temporal and spatial scales, as well as environmental drivers. Measurements of ozone, bromine monoxide (BrO), and meteorology were obtained during several deployments of autonomous, ice-tethered buoys (O-Buoys) from both coastal sites and over the Arctic Ocean; these data were used to characterize observed ODEs. Detected decreases in surface ozone levels during the onset of ODEs corresponded to a median estimated apparent ozone depletion timescale (based on both chemistry and the advection of O-3-depleted air) of 11 h. If assumed to be dominated by chemical mechanisms, these timescales would correspond to larger-than-observed BrO mole fractions based on known chemistry and assumed other radical levels. Using backward air mass trajectories and an assumption that transport mechanisms dominate observations, the spatial scales for ODEs (defined by time periods in which ozone levels <= 15 nmol mol(-1)) were estimated to be 877 km (median), while areas estimated to represent major ozone depletions (< 10 nmol mol(-1)) had dimensions of 282 km (median). These observations point to a heterogeneous boundary layer with localized regions of active, ozone-destroying halogen chemistry, interspersed among larger regions of previously depleted air that retain reduced ozone levels through hindered atmospheric mixing. Based on the estimated size distribution, Monte Carlo simulations showed it was statistically possible that all ODEs observed could have originated upwind, followed by transport to the measurement site. Local wind speed averages were low during most ODEs (median of similar to 3.6 m s(-1)), and there was no apparent dependence on local temperature. C1 [Halfacre, J. W.; Knepp, T. N.; Shepson, P.

We evaluated whether the recommended reduction in chemoprophylaxis in the presence of RA increases VTE rates. METHODS: We collected data each hospital day for all soldiers admitted to the Walter Reed Army Medical Center following injury in Iraq or Afghanistan. We analyzed thromboprophylaxis and RA rates and assessed risk factors for VTE. We separated outcomes by whether RA was central neuraxial (cNAB) or peripheral blockade. RESULTS: Among 1,259 patients, 323 received RA for a median of 12 days (5-27 days). Those with RA were younger and more likely to have been injured in combat or by an improvised explosive device. They also received more packed red blood cell transfusions and had longer admissions. Patients with RA spent a greater percentage of days on enoxaparin 40 mg daily compared with those without RA (34.4% vs. 22.0%, p < 0.001) and more hospital days without any chemoprophylaxis (2.0 [1.0-6.0] vs. 1.0 [0.0-3.0], p G 0.001). Patients with cNAB were less likely to be placed on enoxaparin 30 mg twice daily. Patients with RA in place had mechanical prophylaxis ordered at the same rate as those without RA. Neither the presence of any RA nor cNAB specifically was associated with an increased risk for VTE. No bleeding or neurologic complications occurred in those receiving RA. CONCLUSION: Despite changes to chemoprophylaxis, soldiers wounded in combat who receive RA are not at increased risk for VTE.

The strata are dark-gray mudstone with interbedded first-cycle volcanogenic sandstone and conglomerate-breccia and contain the Tithonian marine pelecypod Buchia piochii. Laser-ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) zircon Pb-206/U-238 ages of 147.9 +/- 3.2 Ma, 145.6 +/- 5.3 Ma, and 144.5 +/- 3.0 Ma measured on volcaniclastic samples from Los Penasquitos and Rancho Valencia Canyons are interpreted as magmatic crystallization ages and are consistent with the Tithonian depositional age indicated by fossils. Whole-rock geochemistry is consistent with an island-arc volcanic source for most of the rocks. The strata of the Penasquitos Formation have been assigned to the Santiago Peak volcanics by many workers, but there are major differences. The Penasquitos Formation is marine; older (150-141Ma); deformed everywhere and overturned in places; and locally is altered to pyrophyllite. In contrast, the Santiago Peak volcanics are nonmarine and contain paleosols in places; younger (128-110 Ma); undeformed and nearly flat lying in many places; and not altered to pyrophyllite. The Penasquitos Formation rocks have also been assigned to the Bedford Canyon Formation by previous workers, but the Bedford Canyon is distinctly less volcanogenic and contains chert, pebbly mudstones, and limestone olistoliths(?) with Bajocian-to Callovian-age fossils. Here, we interpret the Penasquitos Formation as deep-water marine forearc basin sedimentary and volcanic strata deposited outboard of the Peninsular Ranges magmatic arc. The Upper Jurassic Mariposa Formation of the western Sierra Nevada Foothills is a good analog. Results of detrital zircon U/Pb dating from an exposure of continentally derived sandstone at Lusardi Creek are consistent with a mixed volcanic-continental provenance for the Penasquitos Formation. A weighted mean U/Pb age of 144.9 +/- 2.8 Ma from the youngest cluster of detrital grain ages is interpreted as the likely depositional age. Pre-Cordilleran arc zircon age distributions (>285 Ma) are similar to Jurassic deposits from the Colorado Plateau, with dominant Appalachian-derived Paleozoic (300-480 Ma), Pan African (531-641 Ma), and Grenville (950-1335 Ma) grains, consistent with derivation either directly, or through sediment recycling, from the Colorado Plateau Mesozoic basins and related fluvial transport systems. Appalachian-and Ouachita-like detrital zircon age distributions are characteristic of Jurassic Cordilleran forearc basins from northeast Oregon to west-central Baja California, indicating deposition within the same continentfringing west-facing arc system.

The Salton Sea Stochastic Simulation Model ((SM)-M-4) was developed to assist planners and residents of the Salton Sea (SS) transboundary watershed (USA and Mexico) in making sound policy decisions regarding complex water-related issues. In order to develop the (SM)-M-4 with a higher degree of climate forecasting resolution, an in-depth analysis was conducted regarding precipitation and evapotranspiration for the semiarid region of the watershed. Weather station data were compiled for both precipitation and evapotranspiration from 1980 to 2004. Several logistic regression models were developed for determining the relationships among precipitation events, that is, duration and volume, and evapotranspiration levels. These data were then used to develop a stochastic weather generator for S-4 M. Analyses revealed that the cumulative effects and changes of +/- 10 percent in SS inflows can have significant effects on sea elevation and salinity. The aforementioned technique maintains the relationships between the historic frequency distributions of both precipitation and evapotranspiration, and not as separate unconnected and constrained variables.

TI Epidural Lysis of Adhesions for Failed Back Surgery and Spinal Stenosis: Factors Associated with Treatment Outcome SO ANESTHESIA AND ANALGESIA LA English DT Article ID WORKERS-COMPENSATION; PERIDURAL SCAR; PRIMARY-CARE; PAIN; INJECTIONS; SCIATICA; DISEASE; FUSION; HYALURONIDASE; DEGENERATION AB BACKGROUND: Failed back surgery syndrome (FBSS) is a challenging problem. One treatment advocated to treat FBSS is epidural lysis of adhesions (LOA). The results of studies examining LOA for FBSS have been mixed, but are limited because no study has ever sought to identify factors associated with outcomes. METHODS: We performed this multicenter, retrospective study in 115 patients who underwent LOA for FBSS (n = 104) or spinal stenosis (n = 11) between 2004 and 2007. Twenty-seven demographic, clinical, and procedural variables were extracted from medical records and correlated with the outcome, defined as 50% pain relief lasting 1 month. Univariable analysis was performed, followed by multivariable logistic regression. RESULTS: Overall, 48.7% (95% confidence interval [CI], 39.3%-58.1%) of patients experienced a positive outcome. In univariable analysis, those who had a positive outcome were older (mean age 64.1 years; 95% CI, 59.7-68.6 vs 57.2; 95% CI, 53.0-61.4 years; P = 0.02), while higher baseline numerical rating scale pain scores were associated with a negative outcome (mean 6.7 years; 95% CI, 6.0-7.3 vs 7.5; 95% CI, 6.9-8.0; P = 0.07). Use of hyaluronidase did not correlate with outcomes in univariable analysis (odds ratio [OR], 1.2; 95% CI, 0.6-2.5; P = 0.65). In multivariable analysis, age 81 years (OR, 7.8; 95% CI, 1.4-53.7), baseline numerical rating scale score 9 (OR, 4.4; 95% CI, 1.4-16.3, P = 0.02), and patients on or seeking disability or worker's compensation (OR, 4.4; 95% CI, 1.1-19.5, P = 0.04) were significantly more likely to experience a positive outcome. CONCLUSIONS: Considering our modest success rate, selecting patients for epidural LOA based on demographic and clinical factors may help better select treatment candidates. Procedural factors such as the use of hyaluronidase that increase risks and costs did not improve outcomes, so further research is needed before these become standard practice.

TI Serum Free Ropivacaine Concentrations Among Patients Receiving Continuous Peripheral Nerve Block Catheters: Is It Safe for Long-Term Infusions? SO ANESTHESIA AND ANALGESIA LA English DT Article ID PLASMA-CONCENTRATIONS; SCIATIC-NERVE; BUPIVACAINE; TOXICITY; SURGERY; MECHANISMS; UPDATE; TRAUMA; TIME AB BACKGROUND: Ropivacaine is a long-acting local anesthetic used for continuous peripheral nerve catheter infusions. Catheters may remain in situ for prolonged time periods. In the present study, patients were enrolled to receive continuous peripheral nerve catheters with measurement of free serum ropivacaine concentrations. METHODS: Peripheral nerve catheters were placed for postoperative pain management in trauma patients and infused with ropivacaine 0.2% or bolused with 0.5%. Blood samples were obtained from each subject on days 0 (preinfusion), 3, 5, 7, 10, and every third day until catheter removal. Serum free ropivacaine concentrations were measured via high-performance liquid chromatography and were compared using the Wilcoxon signed rank test. RESULTS: One hundred thirty-three blood samples were analyzed in 35 patients; all serum free ropivacaine concentrations after infusion initiation (99 samples from 35 subjects) were below 0.34 mg/L (previously determined toxic threshold). The highest concentration achieved in a blood sample was 0.19 mg/L; all other values were <0.09 mg/L. The total amount of drug received during the study ranged from 1146 to 22,320 mg (median of 3722 mg). Catheters remained in situ for a median of 7 days (range: 3-23). From day 0 to 3 (preinfusion), 77% of the study participants had an increase in the serum free-fraction ropivacaine concentrations. The median concentration on day 3 was 0.025 mg/L (95% upper confidence limit for mean: 0.05, range: <0.01-0.19); P < 0.001 compared with preinfusion levels). From day 3 to 5, 68% of the participants had a decrease in the serum free ropivacaine concentrations (median level 0.016 mg/L [95% upper confidence limit for mean: 0.021] P = 0.007 for day 5 compared with day 3). CONCLUSIONS: In this study, free serum ropivacaine concentrations remained well below toxic values despite large amounts of drug administration in combat-wounded patients. The administration of continuous ropivacaine infusions over prolonged time periods, coupled with multiple drug boluses, did not produce toxic or near-toxic serum concentrations.

However, the structure-property relationship associated with the rostrum has yet to be explored. In this study, the stellate bone properties of the rostrum are examined as a function of spatial location on the rostrum using nanoindentation and Fourier transform infrared spectroscopy. Nanoindentation results indicated a constant elastic modulus along the middle section of the rostrum. However, the elastic modulus exhibited a gradient along the side of the rostrum, with the maximum modulus at the base of the rostrum. This study is part of an overall research project examining the electrosensory capabilities, hydrodynamics and structure-property relationships of the rostrum to develop new materials for force protection applications.

First the theoretical description of this new concept is presented, second GaN:Mg is used as a model system and as an experimental example to show its feasibility. It is shown that above bandgap UV-light illumination during the growth can reduce the passivation and compensation of Mg acceptors in GaN: Mg. The amount of hydrogen impurities, which usually passivates Mg at doping concentrations around Mg: 2x10(19) cm(-3), is significantly reduced by UV-illumination. The resistivity of samples grown with UV is similar to the resistivity of post-growth annealed samples. No post growth annealing was needed to achieve free carrier concentrations consistent with full activation of the p-type GaN. In contrast samples that are doped below Mg:<1x10(18) cm(-3) become n-type conductive when the samples are grown with UV illumination. This observation suggests a reduced incorporation of Mg acceptors due to the UV light. At low Mg doping concentrations the native incorporation of O donors dominates the conductivity over Mg acceptors. UV-illumination therefore reduces compensation of donors by Mg acceptors. Thus, these observations support the concept of UV illumination as a way to control the Fermi level of different charged point defects to control compensation in doped semiconductors.

TI Recent accumulation variability in northwest Greenland from ground-penetrating radar and shallow cores along the Greenland Inland Traverse SO JOURNAL OF GLACIOLOGY LA English DT Article DE accumulation; ground-penetrating radar; ice-sheet mass balance; polar firn ID SHEET MASS-BALANCE; ICE-SHEET; SNOW ACCUMULATION; TRACE-ELEMENT; FIRN CORES; SUMMIT; ANTARCTICA; LAYERS; RATES AB Accumulation is a key parameter governing the mass balance of the Greenland ice sheet. Several studies have documented the spatial variability of accumulation over wide spatial scales, primarily using point data, remote sensing or modeling. Direct measurements of spatially extensive, detailed profiles of accumulation in Greenland, however, are rare. We used 400 MHz ground-penetrating radar along the 1009 km route of the Greenland Inland Traverse from Thule to Summit during April and May of 2011, to image continuous internal reflecting horizons. We dated these horizons using ice-core chemistry at each end of the traverse. Using density profiles measured along the traverse, we determined the depth to the horizons and the corresponding water-equivalent accumulation rates. The measured accumulation rates vary from similar to 0.1 m w.e. a(-1) in the interior to similar to 0.7 m w.e. a(-1) near the coast, and correspond broadly with existing published model results, though there are some excursions. Comparison of our recent accumulation rates with those collected along a similar route in the 1950s shows a similar to 10% increase in accumulation rates over the past 52 years along most of the traverse route. This implies that the increased water vapor capacity of warmer air is increasing accumulation in the interior of Greenland.

[1] Using an array of FPTF as an approach to hyperspectral imaging relaxes wavelength tuning requirements considerably because of the reduced portion of the spectrum that is covered by each element in the array. In this paper, Pacific Advanced Technology and ARL present the results of a concept design and performed analysis of a MOEMS based tunable Fabry-Perot array (FPTF) to perform simultaneous multispectral and hyperspectral imaging with relatively high spatial resolution. The concept design was developed with support of an Army SBIR Phase I program The Fabry-Perot tunable MOEMS filter array was combined with a miniature optics array and a focal plane array of 1024 x 1024 pixels to produce 16 colors every frame of the camera. Each color image has a spatial resolution of 256 x 256 pixels with an IFOV of 1.7 mrads and FOV of 25 degrees. The spectral images are collected simultaneously allowing high resolution spectral-spatial-temporal information in each frame of the camera, thus enabling the implementation of spectral-temporal-spatial algorithms in real-time to provide high sensitivity for the detection of weak signals in a high clutter background environment with low sensitivity to camera motion. The challenge in the design was the independent actuation of each Fabry Perot element in the array allowing for individual tuning. An additional challenge was the need to maximize the fill factor to improve the spatial coverage with minimal dead space. This paper will only address the concept design and analysis of the Fabry-Perot tunable filter array. A previous paper presented at SPIE DSS in 2012 explained the design of the optical array.

TI DIFFERENTIAL CHANGES IN HEPATIC SYNTHESIS OF ALBUMIN AND FIBRINOGEN AFTER SEVERE HEMORRHAGIC SHOCK IN PIGS SO SHOCK LA English DT Article DE Acute phase proteins; stable isotope infusion; protein synthesis; and gas chromatography and mass spectrometry ID LACTATED RINGERS RESUSCITATION; ACUTE-PHASE PROTEINS; COAGULATION FUNCTION; HYDROXYETHYL STARCH; TRAUMA PATIENTS; CLINICAL-TRIAL; METABOLISM; PLASMA; COAGULOPATHY; INJURY AB Introduction Changes of plasma albumin and fibrinogen after various insults have been described as acute phase responses. This study investigated the acute changes of hepatic synthesis of albumin and fibrinogen after hemorrhage and resuscitation with lactated Ringer's (LR) solution or normal saline (NS) in pigs. Methods Twenty anesthetized pigs were randomized into control (n = 6), LR solution (n = 7), and NS (n = 7) groups. Hemorrhage of 60% estimated blood volume was induced in the LR and NS groups by removing blood from the left femoral artery with a computer-controlled pump, followed by resuscitation with either LR solution at three times the bled volume, or NS to reach the same mean arterial pressure as in the LR group. Stable isotope 1-C-13-phenylalanine was infused for 6 h with hourly blood sampling and subsequent gas chromatography and mass spectrometry analysis to quantify hepatic protein synthesis. Results Hemorrhage decreased mean arterial pressure and increased heart rate. Resuscitation with LR solution or NS corrected these changes. Compared with baseline, hemorrhage and resuscitation decreased albumin levels to 49% 2% and 44% +/- 3% and fibrinogen levels to 50% +/- 2% and 53% +/- 2% in LR solution and NS (all P < 0.05), respectively. Albumin synthesis was impaired from 8.8 +/- 1.4 mg/kg per hour (control) to 5.3 +/- 0.8 mg/kg per hour in LR solution and 3.9 +/- 0.6 mg/kg per hour in NS (both P < 0.05). No changes were observed in fibrinogen synthesis after hemorrhage and resuscitation with LR solution (4.4 +/- 0.7 mg/kg per hour) or NS (3.3 +/- 0.4 mg/kg per hour), compared with the control (3.5 +/- 0.3mg/kg per hour). Conclusions Hemorrhage and resuscitation compromised albumin synthesis, but not fibrinogen synthesis. There were no differences in hepatic synthesis of albumin or fibrinogen between LR solution and NS resuscitation.

A comprehensive and detailed study on the performance of GSZO TFTs has been carried out by studying the effects of processing parameters such as deposition temperature and annealing temperature/duration, as well as the channel thickness with all temperatures held below 150 degrees C. Variety of characterization techniques, namely Rutherford backscattering (RBS), x-ray photoelectron spectroscopy (XPS) and x-ray reflectivity (XRR) in addition to I-V and C-V measurements were employed to determine the effects of the above parameters on the composition and quality of the channel. Optimized TFT characteristics of I-D= 3x10(-7) A, I-ON/OFF = 2x10(6), V-ON similar to -2 V, SS similar to 1 V/dec and mu(FE) = 0.14 cm(2) /V center dot s with a Delta V-ON of 3.3 V under 3 hours electrical stress were produced.

The use of a single cavity results in common mode rejection of the noise and drift that would be present in a system of two coupled cavities. We show that the scale-factor-to-mode-width ratio is increased above unity for this system and demonstrate tuning of the scale factor by (i) directly varying the mode coupling via rotation of an intracavity half wave plate, and (ii) coherent control of the cavity reflectance which is achieved simply by varying the incident polarization superposition. These tuning methods allow us to achieve unprecedented enhancements in the scale factor and in the scale-factor-to-mode-width ratio by closely approaching the critical anomalous dispersion condition.

We present a dynamical simulation of Brillouin scattering in a Yb-doped fiber amplifier that numerically solves the differential equations in z and t describing the laser, Stokes and pump waves, the inversion, and the density fluctuations that seed the scattering process. We compare the model to experimental data, and show that a linearly chirped seed laser is an efficient form of SBS suppression; especially for long delivery fibers. The frequency chirp decreases the interaction length by chirping through the Brillouin resonance in a time that is short compared to the fiber transit time. The seed has a highly linear chirp of 10(14)-10(16) Hz/s at 1064 nm which preserves a well-defined phase relationship in time. This method of SBS suppression retains a long effective coherence length for purposes of coherent combining, while at high chirps appears to the SBS as a large linewidth, increasing the threshold. An increase in fiber length increases the laser bandwidth as seen by the SBS, leading to a fiber-length-independent SBS threshold.

Operating a conventional vertical cavity surface-emitting diode laser in an optoelectronic feedback loop can yield a linear frequency chirp of similar to 10(16) Hz/s at a constant output power. The simple and deterministic variation of phase with time preserves temporal coherence, in the sense that it is straightforward to coherently combine multiple amplifiers despite a large length mismatch. The seed bandwidth as seen by the counter-propagating SBS is large, and also increases linearly with fiber length, resulting in a nearly-length-independent SBS threshold. Experimental results at the 600W level will be presented. The impact of a chirped seed on multimode instability is also addressed theoretically.

Despite technological advancements in protective equipment and medical care available during recent military conflicts, TBI is the most common neurological condition among Soldiers and Marines evaluated for discharge from service. This study describes the demographic, service-related, and disability characteristics of Soldiers and Marines referred for combat-related TBI disability evaluation. Methods: Cross-sectional analysis of Soldiers and Marines evaluated for combat-related disability between October 1, 2004 and September 30, 2010 was performed. Traumatic brain injury cases were identified using the Veterans Affairs Schedule for Rating Disabilities code for TBI and compared with other combat-related disabilities. Results: Combat-related TBI disability rates have significantly increased in both the Army and the Marine Corps since 2005. Significantly more unfitting conditions are present on average in combat-related TBI cases than in other combat-related disability cases. Combat-related TBI disability cases are more likely to be medically retired than other types of combat-related disability. Conclusions: Because veterans with combat-related TBI disabilities are likely to require chronic care for TBI-associated medical conditions, disability evaluation policy and programs must ensure that combat-related TBI disabilities are accurately identified and compensated, and the potential long-term care needs are addressed.

Although recent studies have documented safe usage in an adult population, no study to date has investigated its use in a pediatric setting. In addition, most emergency departments feel that splint placement is safer than casting after acute forearm fracture reduction in the pediatric population. However, to our knowledge there is no such study that documents the complication rates associated with immediate casting. The goal of this study was to assess the safety and efficacy of Bier block regional anesthesia and immediate cast application after closed reduction of pediatric forearm fractures. Methods: A retrospective review was conducted of patients treated for forearm fractures in a 2-year period at a major metropolitan pediatric hospital. Rates of complications and length and costs of the 2 procedures were analyzed. Results: A total of 600 patients were treated with Bier block regional anesthesia and 645 were treated with conscious sedation for displaced fractures of the forearm in the 2-year study period. No complications requiring admission were seen in either group. No patient experienced compartment syndrome or a need for readmission secondary to cast application. 2.2% and 4.3% (P=0.0382) of patients in the Bier block and sedation groups, respectively, needed their cast bivalved secondary to swelling. The average time from initiation of procedural sedation to discharge was 1 hour and 42 minutes, whereas the time to discharge from initiation of Bier block regional anesthesia was 47 minutes (P < 0.0001). The average cost for a patient treated with procedural sedation was $6313, whereas the average cost for the Bier block regional anesthesia group was $4956. Conclusions: Bier block regional anesthesia is a safe, efficient, and cost-effective method of reducing pediatric forearm fractures. Immediate cast application can be used without fear of major complications. Levels of Evidence: Level III-retrospective review.

The LPS were grown by MOCVD using patterned low temperature AlN/sapphire substrates: the Al-polar and N-polar AlN grew on AlN buffer layer and nitrided sapphire, respectively. AFM images showed a height difference between the two adjacent domains of different polarity on the order of 30 nm, which was equivalent to the low temperature AlN buffer layer thickness. SEM images provided an insight in the growth mode of the two polarities. It was shown that Al-polar AlN grew two-dimensionally, leading to a smooth well coalesced layer, while N-polar AlN grew primarily three-dimensionally, leading to a columnar structure. This difference in the growth mode led to different properties of domains with opposite polarity, including strain and defect incorporation, as observed by X-ray diffraction, photoluminescence, and Raman spectroscopy measurements. Finally, an outlook on the applicability and future development of AlN-based LPS is given. (C) 2014 WILEY-VCH Verlag GmbH & Co.

Although prior research has not well specified these pathways at the anatomical level, some evidence, both theoretical and empirical, suggest that emotional reactions influence the experience of disease and non-disease-related pains. Other studies suggest that treatments directed at negative emotional responses reduce suffering associated with pain. The current study was conducted to explore the influence of emotional reactions to pain as a predictor of psychological distress in a sample of adult Blacks with Sickle Cell Disease (SCD). Using cross-sectional survey data, we evaluated whether negative emotional reactions to the experience of pain were predictive of psychological distress after controlling for the somatic dimension of pain and age in n = 67 Black patients with Sickle Cell Disease (SCD). Results showed that greater negative emotion associated with pain predicted Somatization (p < .01), Anxiety (p < .05), Phobic Anxiety (p < .05), and Psychoticism (p < .05). Increased negative emotion associated with pain was also predictive of the General Symptoms Index (p < .05) and the Positive Symptoms Total from the SCL-90-R (p < .01). We believe the current study demonstrates that negative emotional reactions to the experience of pain in adults with SCD are predictive of psychological distress above and beyond the influences of age and the direct nociceptive experience. We also believe these data to be valuable in conceptualizing the allocation of treatment resources toward a proactive approach with early identification of patients who are responding poorly for the purpose of potentially reducing later psychopathology. A deeper understanding of the ways that subpopulations cope with chronic disease-related pain may produce models that can be ultimately generalized to the consumers of the majority of healthcare resources.

TI A simple approach for superior performance of lithium/sulphur batteries modified with a gel polymer electrolyte SO JOURNAL OF MATERIALS CHEMISTRY A LA English DT Article ID HIGH-CAPACITY DENSITY; LI-ION BATTERY AB A gel polymer electrolyte (GPE) is superior to a liquid electrolyte in reducing electrolyte leakage and flammability for the safety of rechargeable batteries. However, using GPE in lithium/sulphur (Li/S) batteries reduces the capacity because the highly viscous GPE traps lithium polysulfide (PS) within the electrolyte and makes the PS electrochemically inactive. In order to compensate for the loss of capacity, a porous poly(ethylene oxide)-sulphur composite has been selected to modify the commercial separator. It is shown that elemental sulphur in the composite layer not only serves as the pore-making agent (or called wetting agent) to facilitate filling of the liquid electrolyte in the cell assembly, but also provides additional sulphur to increase the cell's capacity. As a result, the Li/S cell with a GPE-modified separator has even higher capacity than the liquid electrolyte cell while still retaining the advantages of GPE. In this paper we discuss the effect of the composite's composition on the morphology, electrolyte wettability and cell's performance.

Unique features in the electron transport characteristics consisting of a significant enhancement of current at the Si site, diode-like asymmetric current-voltage response, and negative differential resistance are noted for the doped BN monolayer. These features are found to result from new "tunnel" channels induced by the substitutional Si atom near Fermi level in the band gap. The calculated position-projected tunneling currents providing scanning tunneling micrograph clearly discern the site-dependence of the Si atom and can be used to distinguish substitutional sites of atomic dopants in the monolayer.

The objective is to review some of the basic approaches used in the analytical and experimental methods for kinematic and dynamic analysis of flexible mechanical systems, and to identify future directions in this research area. In addition, comparison between uniaxial and multiaxial excitations and their impact on a structure's life-cycles is provided. Theimportance of understanding failure mechanisms in complex structures has led to the development of a vast range of theoretical, numerical, and experimental techniques to address complex dynamical effects. Therefore, it is imperative to identify the failure mechanisms of structures through experimental and virtual failure assessment based on correctly identified dynamic loads. For that reason, techniques for mapping the dynamic loads to fatigue were provided. Future research areas in structural dynamics due to multiaxial excitation are identified as (i) effect of dynamic couplings, (ii) modal interaction, (iii) modal identification and experimental methods for flexible structures, and (iv) computational models for large deformation in response to multiaxial excitation.

The IGVC is a multidisciplinary exercise in product realization that challenges college engineering student teams to integrate advanced control theory, machine vision, vehicular electronics and mobile platform fundamentals to design and build an unmanned system. Teams from around the world focus on developing a suite of dual-use technologies to equip ground vehicles of the future with intelligent driving capabilities. Over the past 21 years, the competition has challenged undergraduate, graduate and Ph.D. students with real world applications in intelligent transportation systems, the military and manufacturing automation. To date, teams from over 80 universities and colleges have participated. This paper describes some of the applications of the technologies required by this competition and discusses the educational benefits. The primary goal of the IGVC is to advance engineering education in intelligent vehicles and related technologies. The employment and professional networking opportunities created for students and industrial sponsors through a series of technical events over the four-day competition are highlighted.

DNA vaccines have been utilized as candidate HIV vaccines because of their ability to generate cellular and humoral immune responses, the lack of anti-vector response allowing for repeat administration, and their ability to prime the response to viral-vectored vaccines. Because the HIV epidemic has disproportionately affected the developing world, the favorable thermostability profile and relative ease and low cost of manufacture of DNA vaccines offer additional advantages. In vivo electroporation (EP) has been utilized to improve immune responses to DNA vaccines as candidate HIV-1 vaccines in standalone or prime-boost regimens with both proteins and viral-vectored vaccines in several animal models and, more recently, in human clinical trials.

Further, we demonstrate its application as a highly sensitive and selective electrochemical sensor for selective determination of As(III) in the presence of other elements, such as Cu and some organic and inorganic molecules. The GO sheets provided the surface for the reduction of silver ions. The composite can be easily used for the construction of a disposable electrochemical sensor on a glassy carbon electrode (GCE) using a drop deposition method. The composite was characterized by scanning and transmission electron microscopies, energy dispersive X-ray spectroscopy, X-ray diffraction and electrochemical impedance spectroscopy. Cyclic voltammetry and anodic stripping voltammetry measurements were employed to evaluate the electrochemical properties of beta cyclodextrin stabilized AgNPs-GO/GCE towards arsenic(III) detection. The AgNPs-GO film exhibited distinctly higher activity for the anodic stripping analysis of As(III) compared to the GO film alone with approximately three times enhancement of the peak current. This nanostructured electrode applied for As(III) analysis displayed a wide linear range (13.33-375.19 nM), a high sensitivity (180.5(mu A mu M-1)) including a 0.24 nM detection limit. We demonstrate the real-life application of the developed sensor by selectively determining the As content in ground and river water samples.

S. Army Engineer Research and Development Center to further investigate the adequacy of the coupling factor approach to shallow-buried or near-surface detonations. Comparisons between these recent experimental results and results of numerical simulations of the ground shock propagation in soil are presented. It was found that the coupling factor curve currently adopted in design of buried structures does not accurately represent the actual ground shock propagation in soil and that different coupling factor curves are needed for different physical quantities of interest in design. The results presented in this paper also suggest that the coupling factor curves are functions of several parameters in addition to the depth of burial and that numerical simulations can capture reasonably well the ground shock propagation of soil stresses and particle velocities.

TI Surface modification of ionic liquid-spun chitin fibers for the extraction of uranium from seawater: seeking the strength of chitin and the chemical functionality of chitosan SO GREEN CHEMISTRY LA English DT Article ID SHRIMP SHELLS AB Chitin fibers, prepared by extracting chitin directly from shrimp shell waste and dry-jet wet spinning from the resulting ionic liquid (1-ethyl-3-methylimidazolium acetate) solution in a one-pot process, were surface modified by taking advantage of the insolubility of chitin in common solvents (e. g., water, organics). In this proof of concept example, the chitin fiber surfaces were first deacetylated using aqueous NaOH to make available the primary amine (the functional group of chitosan) on the surface. Further treatment of the fibers allowed for the task-specific tailoring of the functionality (here we appended amidoxime for the extraction of aqueous uranyl ions from seawater). Compositional analysis and physical property measurements (e. g., tensile strength and thermal decomposition) of the fibers before and after surface modification indicated minimal change to the bulk material; however, spectroscopy and sorption studies of uranyl ions from aqueous solution demonstrated surface modification. The lower cost, one-pot process used in this study resulted in weak and brittle fibers, suggesting that additional purification of the chitin before pulling fibers will greatly improve the strength and utility of the resulting material. Overall, a platform has been developed for the surface modification of chitin fibers that provides both the physical properties of chitin and the functional properties of chitosan, resulting in an advanced material from a biorenewable resource with reduced chemical input.

In the adjuvant setting, appropriate surgical and pathological evaluation guides adjuvant treatment and follow up care focuses on detecting recurrent disease with the intention of improving long term survival. In the neoadjuvant setting, assessing response to chemotherapy prior to surgery to include evaluation for pathologic response can provide prognostic information to help guide follow up care. In the metastatic setting, for those undergoing treatment, it is crucial to determine responders versus non-responders in order to help guide treatment decisions. In this review, we present the current guidelines for monitoring treatment response in the adjuvant, neoadjuvant, and metastatic setting. In addition, we also discuss challenges that are faced in each setting.

Objective: Lung navigation study which is an uncommon soft tissue approach. Methods: As no effective organ radiation dose levels were available for this kind of Cone Beam Computed Tomography application we simulated in our DynaCT (Siemens AG, Forchheim, Germany) suite 2 measurements including 3D acquisition and again for 3D acquisition and 4 endobronchial navigation maneuvers under fluoroscopy towards a nodule after the 8th segmentation in the right upper lobe over a total period of 20 minutes (min). These figures reflect the average complexity and time in our experience. We hereby describe the first time the exact protocol of lung navigation by a Cone Beam Computed Tomography approach. Measurement: The hereby first time measured body radiation doses in that approach showed very promising numbers between 0,98-1,15mSv giving specific lung radiation doses of 0,42-0,38 mSv. Main results: These figures are comparable or even better to other lung navigation systems. Cone Beam Computed Tomography offers some unique features for lung interventionists as a realtime 1-step navigation system in an open structure feasible for endobronchial and transcutaneous approach. Conclusions: Due to this low level of radiation exposure Cone Beam Computed Tomography is expected to attract interventionists interested in using and guiding endobronchial lesions.

In several situations one technique is not enough for efficient diagnosis, therefore we investigated a new diagnostic technique of endobronchial guided biopsies by a Cone Beam Computertomography (CBCT) called DynaCT (SIEMENS AG Forchheim, Germany). Method and Material: In our study 33 incidental solitary pulmonary nodules (iSPNs) (28 malignant, 5 benign; mean diameter 25+/-12mm, shortest distance to pleura 25+/-18mm) were eligible according to in-and exclusion criteria. Realtime and onsite navigation were performed according to our standard protocol. 22 All iSPN were controlled with a second technique when necessary and clinical feasible in case of unspecific or unexpected histological result. In all cases common guidelines of treatment of different iSPNs were followed in a routine manner. Results: Overall navigational yield (ny) was 91% and diagnostic yield (dy) 70%, dy for all accomplished malignant cases (n=28) was 82%. In the subgroup analysis of the invisible iSPN (n=12, 11 malignant, 1 benign; mean diameter 15+/-3mm) we found an overall dy of 75%. For the first time we describe a significant difference in specifity of biopsy results in regards to the position of the forceps in the 3-dimensional volume (3DV) of the iSPN in the whole sample group. Comparing the specifity of biopsies of a 3D-uncentered but inside the outer one third of an iSPN-3DV with the specifity of biopsies of centered forceps position (meaning the inner two third of an iSPN-3DV) reveals a significant (p=0,0375 McNemar) difference for the size group (>1cm) of 0,9 for centered biopsies vs. 0,3 for uncentered biopsies. Therefore only 3D-centered biopsies should be relied on especially in case of a benign result. Conclusion: The diagnostic yield of DynaCT navigation guided transbronchial biopsies (TBB) only with forceps is at least up to twofold higher than conventional TBB for iSPNs <2cm. The diagnostic yield of DynaCT navigation guided forceps TBB in invisible SPNs is at least in the range of other navigation studies which were performed partly with multiple navigation tools and multiple instruments. For future diagnostic and therapeutic approaches it is so far the only onsite and realtime extrathoracic navigation approach (except for computed tomography (CT)-fluoroscopy) in the bronchoscopy suite which keeps the working channel open. The system purchase represents an important investment for hospitals but it is a multidisciplinary and multinavigational tool with possible access via bronchial airways, transthoracical or vascular approach at the same time and on the same table without the need for an expensive disposable instrument use.

Tingle, Jeb S. TI Development of expedient military concrete airfield pavement repairs SO MAGAZINE OF CONCRETE RESEARCH LA English DT Article AB Recent military operations have highlighted the need for modernisation of airfield damage repair capabilities for concrete pavements to eliminate long closure periods. Damaged or distressed military airfield pavements must be repaired using expedient methods and durable materials to minimise the time the pavement is removed from service, and to reduce or eliminate additional closure times for subsequent repairs. As a result of this need, extensive research was conducted to develop multiple concrete pavement repair techniques that could be applied across the full spectrum of military airfield repair operations. Developed methods included placing rapid-setting cementitious materials, foreign object debris covers and precast concrete panels over various backfill materials. Newly developed backfill techniques included poured and injected polyurethane foams and dry-placed, rapid-setting flowable fill. The combination of these materials resulted in several new repair techniques that could return a damaged pavement to aircraft traffic within 4-6 h of initiation of the repair. This paper summarises the development of these repair technologies, and describes their performances under accelerated pavement testing and aircraft validation tests. The paper also includes recommendations as to the suitability of each technique for specific operational scenarios, based on field evaluations.

The cluster-continuum approach was used, where the oxidized PCn cluster was surrounded by the implicit solvent modeled via a polarized continuum model (PCM). The oxidative stability of the PCn (n = 2, 3, and 4) complexes was found to be around 5.4-5.5 V vs. Li+/Li, which is not only lower than the stability of an isolated PC but also lower than the stability of the PC-PF6-, PC-BF4- or PC-ClO4- complexes surrounded by the implicit solvent. The oxidation-induced decomposition reactions were studied. The decomposition products of the oxidized PC2 contained CO2, acetone, propanal, propene, and carboxylic acid in agreement with the previous experimental studies.

TI Assessment of Missouri River floodplain invertebrates during historic inundation: implications for river restoration SO KNOWLEDGE AND MANAGEMENT OF AQUATIC ECOSYSTEMS LA English DT Article DE floodplain; river restoration; inundation; prey base ID SACRAMENTO RIVER; HABITATS; USA; CONNECTIVITY; ZOOPLANKTON; CALIFORNIA; LAKE AB Floodplain connectivity is important to aquatic organisms in large rivers. Anthropogenic alterations regulating the Missouri River have limited connectivity and negatively affected native fauna. Determining the biological response to rare inundation events may be important when considering potential restoration options on a regulated river; thus, we assessed benthic invertebrate and zooplankton communities at three floodplain sites during a historic Missouri River high-water event. Chironomid larvae dominated during most sampling trips and densities were often highest during initial sampling trips with lower densities as high water persisted. Similar trends were evident for rotifer, cladoceran, and copepod densities. Nonmetric multidimensional scaling also showed relatively high dissimilarity of densities between early and late sampling trips for benthic invertebrate and zooplankton communities. As such, short-term inundation may be more beneficial to Missouri River benthic invertebrate (mainly chironomid larvae) and zooplankton production than more prolonged inundation lasting a month or more. Furthermore, restoration projects may be designed at elevations allowing more short-term inundation, which would likely benefit native fishes with additional spawning, nursery, and foraging habitat. Levee setbacks may be an effective restoration option for increasing the amount of habitat available for short-term inundation while potentially providing socioeconomic, flood-risk reduction benefits by enhancing flow conveyance.

TI An interatomic potential for saturated hydrocarbons based on the modified embedded-atom method SO PHYSICAL CHEMISTRY CHEMICAL PHYSICS LA English DT Article ID MOLECULAR-DYNAMICS SIMULATIONS; REACTIVE FORCE-FIELD; ATOMISTIC SIMULATIONS; SURFACE-ENERGY; HCP METALS; MECHANICS; SILICON; REAXFF; ETHANE; PVT AB In this work, we developed an interatomic potential for saturated hydrocarbons using the modified embedded-atom method (MEAM), a reactive semi-empirical many-body potential based on density functional theory and pair potentials. We parameterized the potential by fitting to a large experimental and first-principles (FP) database consisting of (1) bond distances, bond angles, and atomization energies at 0 K of a homologous series of alkanes and their select isomers from methane to n-octane, (2) the potential energy curves of H2, CH, and C2 diatomics, (3) the potential energy curves of hydrogen, methane, ethane, and propane dimers, i. e., (H 2) 2, (CH4) 2, (C 2 H6) 2, and (C3H8) 2, respectively, and (4) pressure-volume-temperature (PVT) data of a dense high-pressure methane system with the density of 0.5534 g cc(-1). We compared the atomization energies and geometries of a range of linear alkanes, cycloalkanes, and free radicals calculated from the MEAM potential to those calculated by other commonly used reactive potentials for hydrocarbons, i. e., second-generation reactive empirical bond order (REBO) and reactive force field (ReaxFF). MEAM reproduced the experimental and/or FP data with accuracy comparable to or better than REBO or ReaxFF. The experimental PVT data for a relatively large series of methane, ethane, propane, and butane systems with different densities were predicted reasonably well by the MEAM potential. Although the MEAM formalism has been applied to atomic systems with predominantly metallic bonding in the past, the current work demonstrates the promising extension of the MEAM potential to covalently bonded molecular systems, specifically saturated hydrocarbons and saturated hydrocarbon-based polymers. The MEAM potential has already been parameterized for a large number of metallic unary, binary, ternary, carbide, nitride, and hydride systems, and extending it to saturated hydrocarbons provides a reliable and transferable potential for atomistic/ molecular studies of complex material phenomena involving hydrocarbon-metal or polymer-metal interfaces, polymer-metal nanocomposites, fracture and failure in hydrocarbon-based polymers, etc. The latter is especially true since MEAM is a reactive potential that allows for dynamic bond formation and bond breaking during simulation. Our results show that MEAM predicts the energetics of two major chemical reactions for saturated hydrocarbons, i. e., breaking a C-C and a C-H bond, reasonably well. However, the current parameterization does not accurately reproduce the energetics and structures of unsaturated hydrocarbons and, therefore, should not be applied to such systems.

The energetic properties of the copper(I) nitrotetrazolate starting material are lost since the nitrotetrazolate is removed into the aqueous phase during rinsing, leaving only non-explosive copper(II) iodate and copper(II) periodate. Based on the results of this investigation, the use of oxidizing components in DBX-1 formulations may be limited due to the readiness of copper(I) to be oxidized to copper(II).

As a polyanionic molecule with high water-binding capacity, PSA increases the intercellular space generating permissive conditions for cell motility. PSA enhances stem cell migration and axon path finding and promotes repair in the lesioned peripheral and central nervous systems, thus contributing to regeneration. As a next step in developing an improved PSA-based approach to treat nervous system injuries, we searched for small organic compounds that mimic PSA and identified as a PSA mimetic 5-nonyloxytryptamine oxalate, described as a selective 5-hydroxytryptamine receptor 1B (5-HT1B) agonist. Similar to PSA, 5-nonyloxytryptamine binds to the PSA-specific monoclonal antibody 735, enhances neurite outgrowth of cultured primary neurons and process formation of Schwann cells, protects neurons from oxidative stress, reduces migration of astrocytes and enhances myelination in vitro. Furthermore, nonyloxytryptamine treatment enhances expression of the neural cell adhesion molecule (NCAM) and its polysialylated form PSA-NCAM and reduces expression of the microtubule-associated protein MAP2 in cultured neuroblastoma cells. These results demonstrate that 5-nonyloxytryptamine mimics PSA and triggers PSA-mediated functions, thus contributing to the repertoire of molecules with the potential to improve recovery in acute and chronic injuries of the mammalian peripheral and central nervous systems.

TI Real-time reverse transcription polymerase chain reaction method for detection of Canine distemper virus modified live vaccine shedding for differentiation from infection with wild-type strains SO JOURNAL OF VETERINARY DIAGNOSTIC INVESTIGATION LA English DT Article DE diagnosis; vaccine virus shedding; real-time reverse transcription polymerase chain reaction; Canine distemper virus ID GENETIC-CHARACTERIZATION; RT-PCR; DOGS; ANIMALS; SHELTER; REGION AB Canine distemper virus (CDV) remains a common cause of infectious disease in dogs, particularly in high-density housing situations such as shelters. Vaccination of all dogs against CDV is recommended at the time of admission to animal shelters and many use a modified live virus (MLV) vaccine. From a diagnostic standpoint for dogs with suspected CDV infection, this is problematic because highly sensitive diagnostic real-time reverse transcription polymerase chain reaction (RT-PCR) tests are able to detect MLV virus in clinical samples. Real-time PCR can be used to quantitate amount of virus shedding and can differentiate vaccine strains from wild-type strains when shedding is high. However, differentiation by quantitation is not possible in vaccinated animals during acute infection, when shedding is low and could be mistaken for low level vaccine virus shedding. While there are gel-based RT-PCR assays for differentiation of vaccine strains from field strains based on sequence differences, the sensitivity of these assays is unable to match that of the real-time RT-PCR assay currently used in the authors' laboratory. Therefore, a real-time RT-PCR assay was developed that detects CDV MLV vaccine strains and distinguishes them from wild-type strains based on nucleotide sequence differences, rather than the amount of viral RNA in the sample. The test is highly sensitive, with detection of as few as 5 virus genomic copies (corresponding to 10(-1) TCID50). Sequencing of the DNA real-time products also allows phylogenetic differentiation of the wild-type strains. This test will aid diagnosis during outbreaks of CDV in recently vaccinated animals.

An ELISA kit manufactured in France employs ovine placenta-sourced antigen and has been used in Europe. Sera from goats experiencing a Q fever abortion storm in the United States were used to compare the sensitivity and specificity of these 2 ELISA formats and the Q fever complement fixation test (CFT). Latent class estimates of sensitivity ranged from 97% to 100% with a specificity of 95-100% for the 2 ELISA kits. Estimates for sensitivity and specificity of the CFT were 89% and 82%, respectively. There was not a significant increase in ELISA sensitivity observed with the ovine-sourced antigen kit in this study. Real-time polymerase chain reactions performed on a portion of the sera found that 15 out of 20 sera were congruent across 4 tests for positive and negative sera.

TI A parameter model of gas exchange for the seasonal sea ice zone SO OCEAN SCIENCE LA English DT Article ID OCEAN MOMENTUM EXCHANGE; FLOE SIZE DISTRIBUTION; ENERGY-TRANSFER; BOUNDARY-LAYER; WAVE SPECTRUM; WIND-SPEED; SIMILARITY; SUMMER; RN-222; FLUXES AB Carbon budgets for the polar oceans require better constraint on air-sea gas exchange in the sea ice zone (SIZ). Here, we utilize advances in the theory of turbulence, mixing and air-sea flux in the ice-ocean boundary layer (IOBL) to formulate a simple model for gas exchange when the surface ocean is partially covered by sea ice. The gas transfer velocity (k) is related to shear-driven and convection-driven turbulence in the aqueous mass boundary layer, and to the mean-squared wave slope at the air-sea interface. We use the model to estimate k along the drift track of ice-tethered profilers (ITPs) in the Arctic. Individual estimates of daily-averaged k from ITP drifts ranged between 1.1 and 22 m d(-1), and the fraction of open water (f) ranged from 0 to 0.83. Converted to area-weighted effective transfer velocities (k(eff)), the minimum value of k(eff) was 10(-5)5 m d(-1) near f = 0 with values exceeding k(eff) = 5 m d(-1) at f = 0.4. The model indicates that effects from shear and convection in the sea ice zone contribute an additional 40% to the magnitude of k(eff), beyond what would be predicted from an estimate of k(eff) based solely upon a wind speed parameterization. Although the ultimate scaling relationship for gas exchange in the sea ice zone will require validation in laboratory and field studies, the basic parameter model described here demonstrates that it is feasible to formulate estimates of k based upon properties of the IOBL using data sources that presently exist.

Retinal pigmented epithelium derived from human induced pluripotent stem (iPS) cells (iPS-RPE) may be a source of cells for transplantation. For this reason, it is essential to determine the functional competence of iPS-RPE. One key role of the RPE is uptake and processing of retinoids via the visual cycle. The purpose of this study is to investigate the expression of visual cycle proteins and the functional ability of the visual cycle in iPS-RPE. METHODS. iPS-RPE was derived from human iPS cells. Immunocytochemistry, RT-PCR, and Western blot analysis were used to detect expression of RPE genes lecithin-retinol acyl transferase (LRAT), RPE65, cellular retinaldehyde-binding protein (CRALBP), and pigment epithelium-derived factor (PEDF). All-trans retinol was delivered to cultured cells or whole cell homogenate to assess the ability of the iPS-RPE to process retinoids. RESULTS. Cultured iPS-RPE expresses visual cycle genes LRAT, CRALBP, and RPE65. After incubation with all-trans retinol, iPS-RPE synthesized up to 2942 +/- 551 pmol/mg protein all-trans retinyl esters. Inhibition of LRAT with N-ethylmaleimide (NEM) prevented retinyl ester synthesis. Significantly, after incubation with all-trans retinol, iPS-RPE released 188 +/- 88 pmol/mg protein 11-cis retinaldehyde into the culture media. CONCLUSIONS. iPS-RPE develops classic RPE characteristics and maintains expression of visual cycle proteins. The results of this study confirm that iPS-RPE possesses the machinery to process retinoids for support of visual pigment regeneration. Inhibition of all-trans retinyl ester accumulation by NEM confirms LRAT is active in iPS-RPE. Finally, the detection of 11-cis retinaldehyde in the culture medium demonstrates the cells' ability to process retinoids through the visual cycle. This study demonstrates expression of key visual cycle machinery and complete visual cycle activity in iPS-RPE.

The crack density parameters before and after exposure were estimated from the shear modulus measured wet and dry of 1 in. thick by 4 in. diameter (25 x 100 mm) disks. Mixtures examined included both granitic and lightweight coarse aggregates in combination with cementitious systems containing either 20% fly ash, 60% fly ash, termed enhanced sustainability, or 60% slag cement. This study found that the changes in crack density parameter resulting from exposure to elevated temperatures appear to be more sensitive to differences between cementitious materials than to differences between aggregate type or cementitious material proportions. A critical finding was that the relationship between initial crack density parameter and changes in crack density parameter were similar regardless of fly ash content.

The importance of osmolality and volume are emphasized when discussing the physiology, assessment, and performance effects of dehydration. The underappreciated physiologic distinction between a loss of hypo-osmotic body water (intracellular dehydration) and an iso-osmotic loss of body water (extracellular dehydration) is presented and argued as the single most essential aspect of dehydration assessment. The importance of diagnostic and biological variation analyses to dehydration assessment methods is reviewed and their use in gauging the true potential of any dehydration assessment method highlighted. The necessity for establishing proper baselines is discussed, as is the magnitude of dehydration required to elicit reliable and detectable osmotic or volume-mediated compensatory physiologic responses. The discussion of physiologic responses further helps inform and explain our analysis of the literature suggesting a >= 2% dehydration threshold for impaired endurance exercise performance mediated by volume loss. In contrast, no clear threshold or plausible mechanism( s) support the marginal, but potentially important, impairment in strength, and power observed with dehydration. Similarly, the potential for dehydration to impair cognition appears small and related primarily to distraction or discomfort. The impact of dehydration on any particular sport skill or task is therefore likely dependent upon the makeup of the task itself (e. g., endurance, strength, cognitive, and motor skill).

In this work, we utilized a new Voronoi-based approach for spatial point pattern analysis that was applied to an experimental dendritic microstructure. This technique utilizes a Voronoi tessellation of space surrounding the dendrite cores to determine nearest neighbors and the local primary dendrite arm spacing. In addition, we compared this technique to a recent distance-based technique and a modification to this using Voronoi tessellations. Moreover, a convex hull-based technique was used to include edge effects for such techniques, which can be important for thin specimens. These methods were used to quantify the distribution of local primary dendrite arm spacings, their spatial distribution, and their correlation with interdendritic eutectic particles for an experimental directionally solidified Ni-based superalloy micrograph. This can be an important step for correlating processing and properties in directionally solidified dendritic microstructures.

OBJECTIVE: To evaluate comprehensively the effect of oculomotor-based vision rehabilitation (OBVR) in individuals with mTBI. METHODS: Twelve subjects with mTBI participated in a cross-over, interventional study involving oculomotor training (OMT) and sham training (ST). Each training was performed for 6 weeks, 2 sessions a week. During each training session, all three oculomotor subsystems (vergence/accommodation/version) were trained in a randomized order across sessions. All laboratory and clinical parameters were determined before and after OMT and ST. In addition, nearvision-related symptoms using the Convergence Insufficiency Symptom Survey (CISS) scale and subjective visual attention using the Visual Search and Attention Test (VSAT) were assessed. RESULTS: Following the OMT, over 80% of the abnormal parameters significantly improved. Reading rate, along with the amplitudes of vergence and accommodation, improved markedly. Saccadic eye movements demonstrated enhanced rhythmicity and accuracy. The improved reading-related oculomotor behaviorwas reflected in reduced symptoms and increased visual attention. None of the parameters changed with ST. CONCLUSIONS: OBVR had a strong positive effect on oculomotor control, reading rate, and overall reading ability. This oculomotor learning effect suggests considerable residual neuroplasticity following mTBI.

For example, rules for predicting the surface chemistry of agents can be applied to the creation of next generation decontaminants, reactive coatings, and protective materials for the warfighter. Here, we describe a multifunctional ultra-high vacuum instrument for conducting comprehensive studies of the adsorption, desorption, and surface chemistry of chemical warfare agents on model and militarily relevant surfaces. The system applies reflection-absorption infrared spectroscopy, x-ray photoelectron spectroscopy, and mass spectrometry to study adsorption and surface reactions of chemical warfare agents. Several novel components have been developed to address the unique safety and sample exposure challenges that accompany the research of these toxic, often very low vapor pressure, compounds. While results of vacuum-based surface science techniques may not necessarily translate directly to environmental processes, learning about the fundamental chemistry will begin to inform scientists about the critical aspects that impact real-world applications.

As the cracks propagate, the natural frequency lowers, leading to a changing stress state. A new method has been developed where the damage accumulation rate is computed in the frequency domain using Linear Elastic Fracture Mechanics (LEFM), stress intensity, and the natural frequency. A finite element model was developed to predict the stress intensity and natural frequency during damage accumulation. Validation of the LEFM technique was done through comparison to experimental data. Reasonably good correlations between the FEM and the analytic model were achieved for the stress intensity and natural frequency.

Enhanced knowledge of the electrochemistry of the anodic oxidation of methanol at platinum electrodes could assist in the attempts to improve the platinum-based electrocatalysts that are commonly employed in that technology. There have been numerous studies of the overall kinetics of the methanol anode including identification of dissolved products and adsorbed species but little has been reported on the quantitative rate of the adsorption process. In the lower range of potentials, where no oxidative products are released to the electrolyte, the adsorption is initiated by an electrochemical dehydrogenation and follows Elovich kinetics over most of the range of fractional surface coverage with methanolic species. Specifically adsorbed anions affect both the rate of methanol adsorption and its oxidation to desorbed products. Published by Elsevier B.V.

TI Maximum Likelihood Analysis of Conflicting Observations in Social Sensing SO ACM TRANSACTIONS ON SENSOR NETWORKS LA English DT Article DE Algorithms; Social sensing; truth discovery; conflicting observations; maximum likelihood estimation; expectation maximization ID EM ALGORITHM; WEB AB This article addresses the challenge of truth discovery from noisy social sensing data. The work is motivated by the emergence of social sensing as a data collection paradigm of growing interest, where humans perform sensory data collection tasks. Unlike the case with well-calibrated and well-tested infrastructure sensors, humans are less reliable, and the likelihood that participants' measurements are correct is often unknown a priori. Given a set of human participants of unknown trustworthiness together with their sensory measurements, we pose the question of whether one can use this information alone to determine, in an analytically founded manner, the probability that a given measurement is true. In our previous conference paper, we offered the first maximum likelihood solution to the aforesaid truth discovery problem for corroborating observations only. In contrast, this article extends the conference paper and provides the first maximum likelihood solution to handle the cases where measurements from different participants may be conflicting. The article focuses on binary measurements. The approach is shown to outperform our previous work used for corroborating observations, the state-of-the-art fact-finding baselines, as well as simple heuristics such as majority voting.

A combinatorial methodology using dye-tagged substrate analogs is described for determining which components of a His-containing helical library display acyl transfer activity. We found that helical peptides display high activity, and amino acids that reinforce this propensity are advantaged. Through this approach two new structural motifs have been discovered that are capable of activating esters in organic solvents. Unlike most acyl transfer catalysts functioning in organic solvents, these catalysts are histidine-rather than N-alkyl histidine-based. Longer peptides with localization of reactive groups on the C-terminal end of the peptide were found to further enhance catalytic activity up to similar to 2800-fold over background.

Stressing with an applied bias reversed the hysteresis rotation in the high temperature I-ds-V-gs transfer characteristics and this behavior, indicative of a multilevel trap model, was explained by charge carriers interacting with traps possibly at the MoS2/dielectric interface and within the CVD grown MoS2. High temperature FET characteristics measured up to 125 degrees C demonstrated pinch-off degradation and the influence of trapping/detrapping rates in both the top and bottom gate dielectric. This indicates the importance of maintaining oxide and interface quality for good FET performance. Published by Elsevier Ltd. C1 [Shah, P. B.; Amani, M.; Chin, M. L.; O'Regan, T. P.; Crowne, F.

While the development of new antibiotics remains one option in the fight against bacteria that have become resistant to currently available antibiotics, an attractive alternative is the development of adjuvant therapeutics that restore the efficacy of existing antibiotics. We report a small molecule adjuvant that suppresses colistin resistance in multidrug resistant Acinetobacter baumannii and Klebsiella pneumoniae by interfering with the expression of a two-component system. The compound downregulates the pmrCAB operon and reverses phosphoethanolamine modification of lipid A responsible for colistin resistance. Furthermore, colistin-susceptible and colistin-resistant bacteria do not evolve resistance to combination treatment. This represents the first definitive example of a compound that breaks antibiotic resistance by directly modulating two-component system activity.

This extended response, combined with its natural abundance, low cost, and amenability to manufacturing processes, makes aluminum a highly promising material for commercial applications. Fabricating Al-based nanostructures whose optical properties correspond with theoretical predictions, however, can be a challenge. In this work, the Al plasmon resonance is observed to be remarkably sensitive to the presence of oxide within the metal. For Al nanodisks, we observe that the energy of the plasmon resonance is determined by, and serves as an optical reporter of, the percentage of oxide present within the Al. This understanding paves the way toward the use of aluminum as a low-cost plasmonic material with properties and potential applications similar to those of the coinage metals.

Cyanide and thiocyanate were simultaneously analyzed by high-performance liquid chromatography tandem mass spectrometry in negative ionization mode after rapid and simple sample preparation. Isotopically labeled internal standards, (NaCN)-C-13-N-15 and (NaSCN)-C-13-N-15, were mixed with swine plasma (spiked and nonspiked), proteins were precipitated with acetone, the samples were centrifuged, and the supernatant was removed and dried. The dried samples were reconstituted in 10 mM ammonium formate. Cyanide was reacted with naphthalene-2,3-dicarboxaldehyde and taurine to form N-substituted 1-cyano[f]benzoisoindole, while thiocyanate was chemically modified with monobromobimane to form an SCN-bimane product. The method produced dynamic ranges of 0.1-50 and 0.2-50 mu M for cyanide and thiocyanate, respectively, with limits of detection of 10 nM for cyanide and 50 nM for thiocyanate. For quality control standards, the precision, as measured by percent relative standard deviation, was below 8 %, and the accuracy was within +/- 10 % of the nominal concentration. Following validation, the analytical procedure successfully detected cyanide and thiocyanate simultaneously from the plasma of cyanide-exposed swine.

Perhaps surprisingly, existing results regarding its uniqueness properties are rather limited, and there is much room for improvement in terms of algorithms as well. Uniqueness aspects of NMF are revisited here from a geometrical point of view. Both symmetric and asymmetric NMF are considered, the former being tantamount to element-wise non-negative square-root factorization of positive semidefinite matrices. New uniqueness results are derived, e. g., it is shown that a sufficient condition for uniqueness is that the conic hull of the latent factors is a superset of a particular second-order cone. Checking this condition is shown to be NP-complete; yet this and other results offer insights on the role of latent sparsity in this context. On the computational side, a new algorithm for symmetric NMF is proposed, which is very different from existing ones. It alternates between Procrustes rotation and projection onto the non-negative orthant to find a non-negative matrix close to the span of the dominant subspace. Simulation results show promising performance with respect to the state-of-art. Finally, the new algorithm is applied to a clustering problem for co-authorship data, yielding meaningful and interpretable results.

These spherical image states exist within surface potentials formed by the competition between the attractive image potential and the repulsive centripetal force arising from the angular motion. The image potential has a power law rather than a logarithmic behavior. This leads to fundamental differences in the nature of the effective potential for the two geometries. Our calculations have shown that the captured charge is more strongly localized closest to the surface for fullerenes than for cylindrical nanotube.

TI Concurrent Computational and Dimensional Analyses of Design of Vehicle Floor-Plates for Landmine-Blast Survivability SO JOURNAL OF MATERIALS ENGINEERING AND PERFORMANCE LA English DT Article DE dimensional analysis; landmine detonation; vehicle hull-floor design ID MULTIPURPOSE WHEELED VEHICLE; MATERIAL MODEL; WATER SATURATION; SAND; PERFORMANCE; DETONATION AB Development of military vehicles capable of surviving landmine blast is seldom done using full-scale prototype testing because of the associated prohibitively-high cost, the destructive nature of testing, and the requirements for major large-scale experimental-test facilities and a large crew of engineers committed to the task. Instead, tests of small-scale models are generally employed and the model-based results are scaled up to the full-size vehicle. In these scale-up efforts, various dimensional analyses are used whose establishment and validation requires major experimental testing efforts and different-scale models. In the present work, an approach is proposed within which concurrent and interactive applications of the computational analyses (of landmine detonation and the interaction of detonation products and soil ejecta with the vehicle hull-floor) and the corresponding dimensional analysis are utilized. It is argued that this approach can guide the design of military-vehicle hull-floors which provide the required level of protection to the vehicle occupants under landmine blast attack without introducing unnecessarily high weight to the vehicle. To validate this approach, a combined Eulerian/Lagrangian formulation for landmine detonation and the interaction of detonation products and soil ejecta with the vehicle hull-floor (developed in our previous work) has been utilized along with the experimental results pertaining to small-scale model and full-scale vehicle testing.

TI A Fatigue Model for Discontinuous Particulate-Reinforced Aluminum Alloy Composite: Influence of Microstructure SO JOURNAL OF MATERIALS ENGINEERING AND PERFORMANCE LA English DT Article DE aluminum alloy 6061-T6; discontinuous reinforcement; fatigue; metal matrix composites; microstructure; modeling ID METAL-MATRIX COMPOSITES; LOW-CYCLE FATIGUE; SILICON-CARBIDE PARTICULATE; FRACTURE-BEHAVIOR; CRACK-GROWTH; AL2O3-PARTICLE-REINFORCED 6061-ALUMINUM-ALLOY; ELEVATED-TEMPERATURE; TENSILE PROPERTIES; HIGH-RATES; STRAIN AB In this paper, the use of a microstructure-sensitive fatigue model is put forth for the analysis of discontinuously reinforced aluminum alloy metal matrix composite. The fatigue model was used for a ceramic particle-reinforced aluminum alloy deformed under conditions of fully reversed strain control. Experimental results revealed the aluminum alloy to be strongly influenced by volume fraction of the particulate reinforcement phase under conditions of strain-controlled fatigue. The model safely characterizes the evolution of fatigue damage in this aluminum alloy composite into the distinct stages of crack initiation and crack growth culminating in failure. The model is able to capture the specific influence of particle volume fraction, particle size, and nearest neighbor distance in quantifying fatigue life. The model yields good results for correlation of the predicted results with the experimental test results on the fatigue behavior of the chosen aluminum alloy for two different percentages of the ceramic particle reinforcement. Further, the model illustrates that both particle size and volume fraction are key factors that govern fatigue lifetime. This conclusion is well supported by fractographic observations of the cyclically deformed and failed specimens. C1 [McCullough, R. R.; Jordon, J. B.; Brammer, A.

Change in snow albedo values associated with changing climate conditions can be monitored remotely from satellite platforms viewing the entire Greenland ice sheet, yet comparisons to high quality surface measurements are necessary to assess the accuracy of satellite measurements as new snow albedo algorithms are developed with higher spatial and temporal resolution. During May, June, and July 2011, we obtained daily measurements of spectral albedo at Summit, Greenland with an Analytical Spectral Devices (ASD) spectroradiometer, scanning at 350-2200 nm. We compare our spectral albedo field measurements to the Moderate Resolution Imaging Spectrometer (MODIS), using both the Version 005 Direct Broadcast daily albedo product and the recently developed Version 006 MCD43A daily albedo product. The spectral field measurements allow calculation of weighted integrals to compare to seven MODIS narrow bandwidths ranging the UV through Infrared, as well as a broadband integration to compare to the MODIS shortwave albedo. We additionally compare our field measurements to albedo measured at the Baseline Surface Radiation Network (BSRN) station at Summit. Using the MODIS Version 005 Direct Broadcast product, high-quality retrievals only, comparison to field measurements results in root mean square error (RMSE) of 0.033 for the MODIS shortwave product, and RMSE for the MODIS narrow bandwidths ranging 0.022-0.077. The new MODIS Version 006 product shows considerable improvement, with shortwave RMSE of 0.026, and narrow bandwidths ranging 0.020-0.048. These error values for the Version 006 albedo product show an improvement in reported error values from previous MODIS field validations in Greenland, which have been limited to broadband data from the Greenland Climate Network Automatic Weather Stations.

TI Thermal deconvolution: Accurate retrieval of multispectral infrared emissivity from thermally-mixed volcanic surfaces SO REMOTE SENSING OF ENVIRONMENT LA English DT Article DE Thermal infrared; ASTER; Emissivity; Deconvolution; Shortwave infrared ID REFLECTION RADIOMETER ASTER; ACTIVE LAVA FLOW; KILAUEA VOLCANO; LASCAR VOLCANO; SATELLITE DATA; 2003 ERUPTION; TIR DATA; SPACEBORNE; FIELD; SPECTROSCOPY AB The thermal infrared (TIR) wavelength region has proved highly useful for remotely extracting important parameters of volcanic activity, such as the composition, texture, and temperature of either the surface or gas/aerosol emissions. However, each of these characteristics can vary within the area of one pixel of a remote sensing dataset. which ultimately affects the accuracy of the retrieval of these characteristics. For example, where multiple temperatures occur in a particular pixel, the derived emissivity spectrum and pixel-integrated brightness temperature for that pixel are inaccurate. We present a new approach for deconvolving thermally-mixed pixels in a day/night pair of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) thermal infrared (TIR) scenes over Kilauea volcano, acquired during an active effusive phase in October 2006. The thermal deconvolution algorithm identifies thermally-mixed pixels and determines the multiple temperature components and their area, using data from the higher spatial resolution short wave infrared (SWIR) channels of ASTER. The effects of thermal mixing on the emissivity retrievals were quantified using a spectral deconvolution approach comparing the original to the thermally deconvolved data. The root mean squared (RMS) error improved slightly from.0.879 to 0.813, whereas the compositional end-members changed more dramatically (e.g., glass decreased from 70.2% to 49.3% and the vesicularity increased from 0.7% to 16.3%). The results provide more accurate temperature and emissivity data derived from ASTER data over thermally-elevated surfaces such as volcanoes and fires. This approach also serves as rapid means for accurately identifying sub-pixel temperatures, commonly obscured in low to medium spatial resolution orbital datasets. Moreover, it minimizes processing time, allowing critical information to be quickly disseminated. Published by Elsevier Inc.

Vehicle systems with transient thermal profiles are classified according to operating temperatures in the range of 0-800 degrees C. Thermal conditions of those applications are examined relative to their impact on thermal buffer requirements, and prior phase change thermal enhancement studies for these applications are discussed. In addition a comprehensive overview of phase change materials covering the relevant operating range is given, including selection criteria and a detailed list of over 700 candidate materials from a number of material classes. Promising material candidates are identified for each vehicle system based on system temperature, specific and volumetric latent heat, and thermal conductivity. Based on the results of previous thermal load leveling efforts, there is the potential for making significant improvements in both emissions reduction and overall energy efficiency by further exploration of PCM thermal buffering on vehicles. Recommendations are made for further material characterization, with focus on the need for improved data for metallic and solid-state phase change materials for high energy density applications.

Primary, or nonmotile, cilia function as sensory organelles involved in the regulation of cell growth, differentiation, and homeostasis. Cilia are present in nearly every cell in the body and mutations of genes encoding ciliary proteins affect multiple organs, including the kidneys, liver, pancreas, retina, central nervous system (CNS), and skeletal system. Genetic mutations causing ciliary dysfunction result in a large number of heterogeneous phenotypes that can manifest with a variety of overlapping abnormalities in multiple organ systems. Renal manifestations of ciliopathies are the most common abnormalities and include collecting duct dilatation and cyst formation in autosomal recessive polycystic kidney disease (ARPKD), cyst formation anywhere in the nephron in autosomal dominant polycystic kidney disease (ADPKD), and tubulointerstitial fibrosis in nephronophthisis, as well as in several CNS and skeletal malformation syndromes. Hepatic disease is another common manifestation of ciliopathies, ranging from duct dilatation and cyst formation in ARPKD and ADPKD to periportal fibrosis in ARPKD and several malformation syndromes. The unifying molecular pathogenesis of this emerging class of disorders explains the overlap of abnormalities in disparate organ systems and links diseases of widely varied clinical features. It is important for radiologists to be able to recognize the multisystem manifestations of these syndromes, as imaging plays an important role in diagnosis and follow-up of affected patients.

The Karp genotype was found in all of the chiggers examined, whereas Gilliam and UT302 genotypes were only observed in combination with the Karp genotype. From analysis of these OT genotypes after transmission from chiggers to mice it was determined that with the Lc and Li mites, the OT genotype composition in the rodent spleens post-infection had not changed and therefore resembled that observed in the feeding chiggers. However, only the Karp genotype was found in rodents after feeding by Ld chiggers carrying Karp and Gilliam genotypes. The current findings reveal a complex association among the host, pathogen, and vector. C1 US Army Med Component Armed Forces Res Inst Med S, Dept Entomol, Bangkok, Thailand.

Assays used to measure antibodies against viral proteins involved in protection included a hemagglutination inhibition (HI) assay and a neuraminidase inhibition (NI) assay. Viral neutralization by antibodies against avian influenza H5N1 and 2009 pH1N1 was assessed by influenza (H5) pseudo-typed lentiviral particle-based and H1N1 microneutralization assays. Some US military personnel had cross-neutralizing antibodies against H5N1 (14%) and 2009 pH1N1 (16.5%). The odds of having cross-neutralizing antibodies against 2009 pH1N1 were 4.4 times higher in subjects receiving more than five inactivated whole influenza virus vaccinations than those subjects with no record of vaccination. Although unclear if the result of prior vaccination or disease exposure, these preexisting antibodies may prevent or reduce disease severity.

SO AQUATIC BOTANY LA English DT Article DE Zostera japonica; Zostera marina; Light; Photosynthesis; Carbon balance; Introduced species ID TEMPORAL PATTERNS; RESPONSE CURVES; NORTH-AMERICA; GROWTH; BAY; USA; TEMPERATURE; WASHINGTON; IRRADIANCE; SEEDLINGS AB On the Pacific coast of North America two seagrass species in the genus Zostera co-exist; the native species Zostera marina, and an introduced species, Zostera japonica. These two species typically occupy separate tidal elevations, with Z. marina occupying the lower intertidal and shallow subtidal zones, and Z. japonica occupying the mid- to upper intertidal zone. This study was designed to compare the photosynthetic characteristics of Z. japonica and Z. marina after exposure to high and low light. Nursery pots containing Z. japonica and Z. marina were grown intermixed in replicate mesocosm tanks at two different light levels (50 and 150 mu mol photons m(-2) s(-1)). We measured photosynthetic parameters for Z. japonica and Z. marina leaf segments and whole plants (WP). Z. japonica leaf segment photosynthetic efficiency (alpha) was greater than that of Z. marina and based on the high photosynthetic rate, alpha and saturating irradiance, we suggest that Z. japonica is high light adapted. Whole plant (WP) photosynthetic rates were similar 123 +/- 11 vs. 155 +/- 21 mu mol O-2 gDW(-1) h(-1) for Z. marina and Z. japonica respectively. However, the WP respiration rate of Z. japonica was 2 fold greater than Z. marina. Consequently, Z. marina would be expected to acquire and store more carbon than Z. japonica. We suggest that light limitation does not explain the observed disjunct vertical distribution of these two species and that other factors (e.g. rhizome growth, branching frequency and seed germination, etc.) likely play a large role in controlling Z. japonica colonization.

S. military, the most common types of disability conditions, and the prevalence of combat exposures in the disability population. Previous studies of disability in the U. S. military have focused on a particular service or condition rather than examining the epidemiology of disability in the military overall. Objective: This study's objective is to describe rates of disability evaluation and retirement in U. S. Army, Navy, and Marine Corps. Methods: A cross-sectional study of 126,170 service members evaluated for disability discharge from the U. S. military in fiscal years 2005-2011 was conducted. Crude and standardized rates of disability evaluation and retirement were calculated per 10,000 service members by year of disability, demographic characteristics, and type of disability evaluation or retirement. Temporal trends in the prevalence of combat-related disability in the disability evaluated and retired population were also examined. Results: Rates of disability evaluation and retirement were highest among female, enlisted, and active duty service members. Overall rates of disability evaluation significantly decreased, while rates of disability retirement increased. Rates of psychiatric disability evaluation and retirement significantly increased in all services during the same time period from 2005 to 2011. Combat-related disability evaluations and retirements have substantially increased in all services particularly among psychiatric disability cases. Conclusions: Psychiatric disability, combat-related disability, and disability retirement continue to increase in the military, despite observed decreases in the rates of disability the Department of Defense since 2005.

The phase behavior of ethylene carbonate (EC)-LiTFSI mixtures indicates that two crystalline solvates form-(EC)(3):LiTFSI and (EC)(1):LiTFSI. Crystal structures for these were determined to obtain insight into the ion and solvent coordination. Between these compositions, however, a crystallinity gap exists. A Raman spectroscopic analysis of the EC solvent bands for the 3-1 and 2-1 EC-LiTFSI liquid electrolytes indicates that similar to 86 and 95%, respectively, of the solvent is coordinated to the Li+ cations. This extensive coordination results in significantly improved anodic oxidation and thermal stabilities as compared with more dilute (i.e., 1 M) electrolytes. Further, while dilute EC-LiTFSI electrolytes extensively corrode the Al current collector at high potential, the concentrated electrolytes do not. A new mechanism for electrolyte corrosion of Al in Li-ion batteries is proposed to explain this. Although the ionic conductivity of concentrated EC-LiTFSI electrolytes is somewhat low relative to the current state-of-the-art electrolyte formulations used in commercial Li-ion batteries, using an EC-diethyl carbonate (DEC) mixed solvent instead of pure EC markedly improves the conductivity.

TI Untangling drivers of species distributions: Global sensitivity and uncertainty analyses of MAXENT SO ENVIRONMENTAL MODELLING & SOFTWARE LA English DT Article DE GLOBAL sensitivity analysis; Uncertainty analysis; MAXENT; Snowy Plover; Land cover; Sea level rise ID SAMPLE SELECTION BIAS; SEA-LEVEL RISE; GEOGRAPHIC DISTRIBUTIONS; SNOWY PLOVERS; MODELS; PERSPECTIVE; HABITAT; DESIGN AB Untangling drivers of systems and uncertainty for species distribution models (SDMs) is important to provide reliable predictions that are useful for conservation campaigns. This is particularly true for species whose habitat is threatened by climate change that enhances the uncertainty in future species distributions. Global sensitivity and uncertainty analyses (GSUA) is a robust method to globally investigate the uncertainty of SDMs and the importance of species distributions' drivers in space and time. Here we apply GSUA to MAXENT that is one of the popular presence-only SDMs. We consider the Snowy Plover (Charadrius alexandrinus nivosus) (SP) in Florida that is a shorebird whose habitat is affected by sea level rise due to climate change. The importance of intrinsic and exogenous input factors to the uncertainty of the species distribution is evaluated for MAXENT. GSUA is applied for three projections of the habitat (2006, 2060, and 2100) according to the A1B sea level rise scenario. The large land cover variation determines a moderate decrease in habitat suitability in 2060 and 2100 prospecting a low risk of decline for the SP. The regularization parameter for the environmental features, the uncertainty into the classification of salt-marsh, transitional marsh, and ocean beach, and the maximum number of iterations for the model training are in this order the most important input factors for the average habitat suitability. These results are related to the SP but, in general MAXENT appears as a very non-linear model where uncertainty mostly derives from the interactions among input factors. The uncertainty of the output is a species-specific variable. Thus, GSUA need be performed for each case considering local exogenous input factors of the model. GSUA allows quantitative informed species-management decisions by providing scenarios with controlled uncertainty and confidence over factors' importance that can be used by resource managers.

The thickness of the CNT sheet was found to have a significant impact on the radiation performance of the patch antenna due to the material skin depth, with an similar to 5.5-dB improvement to the realized gain achieved when the CNT sheet thickness was increased from 0.5 mu m to 5 mu m, likely due to lower surface impedance. The 5 mu m-CNT sheet patch antenna exhibited 2.1-dBi total realized gain compared with 5.6-dBi realized gain for baseline copper patch antenna yielding a 3.5-dB reduction attributable to the material substitution. A unique polarization sensitivity behavior was seen by adjusting the alignment of the CNTs within the CNT sheet patch structure. Optimal RF performance was observed when the CNTs within the sheet material were aligned with the E-plane of the patch antenna. When the CNT alignment was orthogonal to that of the E-plane of the patch antenna, the realized gain was reduced by over 8 dB. The input reactance changes from inductive to capacitive due to the geometry and alignment of the CNTs within the patch.

However, there are currently no accurate and reliable diagnostic methods to provide critical, real-time information for early detection of DENV within the vector populations to implement appropriate vector control and personal protective measures. In this article, we report the ability of an immuno-chromatographic assay developed by VecTOR Test Systems Inc. to detect DENV in a pool of female Aedes mosquitoes infected with any of the four viral serotypes. The DENV dipstick assay was simple to use, did not require a cold chain, and provided clear results within 30 min. It was highly specific and did not cross-react with samples spiked with West Nile, yellow fever, Japanese encephalitis, Rift Valley fever, chikungunya, Venezuelan equine encephalomyelitis, Ross River, LaCrosse, or Caraparu viruses. The DENV assay can provide real-time critical information on the presence of DENV in mosquitoes to public health personnel. Results from this assay will allow a rapid threat assessment and the focusing of vector control measures in high-risk areas.

DUGV was mostly recovered from R. pulchellus from sheep and cattle, and DHOV from R. pulchellus from sheep. All Kupe virus isolates were from Isiolo ticks, including R. pulchellus from all the livestock, A. gemma and Amblyomma variegatum F. from cattle, and H. truncatum from goat. NRIV was obtained from R. pulchellus and A. gemma sampled from cattle in Isiolo and Garissa, respectively, while all DHOV and most DUGV (n = 12) were from R. pulchellus sampled from cattle in Garissa. DUGV was also recovered from H. truncatum and Amblyomma hebraeum Koch from cattle and from Rhipicephalus annulatus Say from camel. This surveillance study has demonstrated the circulation of select tick-borne viruses in parts of eastern and northeastern provinces of Kenya, some of which are of public health importance. The isolation of NRIV from ticks is particularly significant because it is usually known to be a mosquito-borne virus affecting humans.

Since quantitative indicators could not accurately measure who was winning the "War in the Villages," it relies instead upon qualitative assessments made by U.S. Province Senior Advisors the Americans best qualified to make such judgments.

TI Sleep and sadness: exploring the relation among sleep, cognitive control, and depressive symptoms in young adults SO SLEEP MEDICINE LA English DT Article DE Sleep; Circadian rhythm; Actigraphy; Cognitive control; Depression; CLOCK gene ID CIRCADIAN-RHYTHMS; ATTENTIONAL BIAS; WORKING-MEMORY; DEPRIVATION; PERFORMANCE; QUALITY; MOOD; INFORMATION; DISRUPTION; ACTIGRAPHY AB Background: Sleep disturbance is a common feature of depression. However, recent work has found that individuals who are vulnerable to depression report poorer sleep quality compared to their low-risk counterparts, suggesting that sleep disturbance may precede depression. In addition, both sleep disturbance and depression are related to deficits in cognitive control processes. Thus we examined if poor sleep quality predicts subsequent increases in depressive symptoms and if levels of cognitive control mediated this relation. Methods: Thirty-five undergraduate students participated in two experimental sessions separated by 3 weeks. Participants wore an actigraph watch between sessions, which provided an objective measure of sleep patterns. We assessed self-reported sleep quality and depressive symptoms at both sessions. Last, individuals completed an exogenous cuing task, which measured ability to disengage attention from neutral and negative stimuli during the second session. Results: Using path analyses, we found that both greater self-reported sleep difficulty and more objective sleep stability measures significantly predicted greater difficulty disengaging attention (i.e., less cognitive control) from negative stimuli. Less cognitive control over negative stimuli in turn predicted increased depression symptoms at the second session. Exploratory associations among the circadian locomotor output cycles kaput gene, CLOCK, single nucleotide polymorphism (SNP), rs11932595, as well as sleep assessments and depressive symptoms also are presented. Conclusions: These preliminary results suggest that sleep disruptions may contribute to increases in depressive symptoms via their impact on cognitive control. Further, variation in the CLOCK gene may be associated with sleep quality. (C) 2013 Elsevier B. V. All rights reserved. C1 [Vanderlind, W.

TI Ranking Site Vulnerability to Increasing Temperatures in Southern Appalachian Brook Trout Streams in Virginia: An Exposure-Sensitivity Approach SO TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY LA English DT Article ID POTENTIAL HABITAT LOSS; CLIMATE-CHANGE; NATIVE RANGE; FISH; POPULATIONS; FRAGMENTATION; MOUNTAINS; REGIME; LIMITS; MODEL AB Models based on simple air temperature-water temperature relationships have been useful in highlighting potential threats to coldwater-dependent species such as Brook Trout Salvelinus fontinalis by predicting major losses of habitat and substantial reductions in geographic distribution. However, spatial variability in the relationship between changes in air temperature to changes in water temperature complicates predictions. We directly measured paired summer air and water temperatures over 2years in a stratified representative sample of watersheds (<1-274km(2)) supporting wild Brook Trout throughout Virginia near the southern edge of the species distribution. We used the temperature data to rank streams in terms of two important components of habitat vulnerability: sensitivity (predicted change in water temperature per unit increase in air temperature) and exposure (predicted frequency, magnitude, and duration of threshold water temperatures). Across all sites, sensitivity was substantially lower (median sensitivity = 0.35 degrees C) than the 0.80 degrees C assumed in some previous models. Median sensitivity across all sites did not differ between the 2years of the study. In contrast, median exposure was considerably greater in 2010 (a particularly warm summer) than in 2009, but exposure ranks of habitat patches were highly consistent. Variation in sensitivity and exposure among habitat patches was influenced by landscape metrics (percent forested riparian corridor, patch area, and elevation), but considerable unexplained variation in sensitivity and exposure among sites was likely due to local-scale differences in the extent of groundwater influence. Overall, our direct measurement approach identified significantly more Brook Trout habitat patches with low sensitivity and low exposure that may persist under warming air temperatures than did previous large-scale models. Our sensitivity and exposure classification should provide a useful general framework for managers in making investment decisions for protecting and restoring Brook Trout habitat.

The HP germination of multiple individual Bacillus subtilis spores in a diamond anvil cell (DAC) was monitored with phase-contrast microscopy. Major conclusions were that (i) >95% of wild-type spores germinated in 40 min in a DAC at similar to 150 MPa and 37 degrees C but individual spores' germination kinetics were heterogeneous; (ii) individual spores' HP germination kinetic parameters were similar to those of nutrient-triggered germination with a variable lag time (T-lag) prior to a period of the rapid release (Delta T-release) of the spores' dipicolinic acid in a 1:1 chelate with Ca2+ (CaDPA); (iii) spore germination at 50 MPa had longer average T-lag values than that at similar to 150 MPa, but the Delta T-release values at the two pressures were identical and HPs of <10 MPa did not induce germination; (iv) B. subtilis spores that lacked the cortex-lytic enzyme CwlJ and that were germinated with an HP of 150 MPa exhibited average Delta T-release values similar to 15-fold longer than those for wild-type spores, but the two types of spores exhibited similar average T-lag values; and (v) the germination of wild-type spores given a >= 30-s 140-MPa HP pulse followed by a constant pressure of 1 MPa was the same as that of spores exposed to a constant pressure of 140 MPa that was continued for >= 35 min; (vi) however, after short 150-MPa HP pulses and incubation at 0.1 MPa (ambient pressure), spore germination stopped 5 to 10 min after the HP was released. These results suggest that an HP of similar to 150 MPa for <= 30 s is sufficient to fully activate spores' GRs, which remain activated at 1 MPa but can deactivate at ambient pressure.

Recently a mouse model was generated in which a chimeric protein consisting of HIF-1 alpha oxygen-dependent degradation domain (ODD) fused to luciferase was ubiquitously expressed in all tissues. Hypoxic stress leads to the accumulation of ODD-luciferase in the tissues of this mouse model which can be identified by noninvasive bioluminescence measurement. Crossing this transgenic mouse with tumorigenic mice yields solid tumors with hypoxic cores that may be successfully imaged and characterized using the technique described herein.

A data assimilation methodology focused on the surface and the PBL, previously tested in a one-dimensional version of MM5, is applied to 29 May, 6 June, and 7 June 2002 during the International Project over the Southern Great Plains. Model-predicted PBL depth is evaluated against PBL depth diagnosed from data across 4,800 km of airborne lidar data (flight tracks 100-300 km long). The forecast with data assimilation verifies better against observations and is thus used to investigate the environmental conditions that govern PBL depth. The spatial structure in PBL depth is found to be most affected by spatial variations in surface buoyancy flux and capping inversion strength. The spatial scales of surface flux forcing reflected in the PBL depth are found through Fourier analysis and multiresolution decomposition. Correlations are at scales of 64 km or less and increase at larger scales for 29 May and 6 June, but on 7 June low correlations are found at all scales, possibly due to greater within-PBL wind speeds, a stronger capping inversion on this day, and clouds. The results suggest a minimum scale, a function of wind speed, below which heterogeneity in surface buoyancy fluxes is not reflected directly in PBL depth.

Transparent nylon monofilaments are mechanically worked to form flattened nylon ribbons, which are then combined with index-matched epoxy resin to create transparent composites. A range of optical and mechanical experiments are performed on composites and surrogate systems in order to quantify properties and guide system design. The results show that these polymer-polymer composites provide good transparency over a wide temperature range, and superior ballistic penetration resistance compared to monolithic transparent polymers.

On the Pacific coast of North America, at least two congeners of Zostera occur: native Zostera marina, and introduced, Zostera japonica. Z. japonica is considered "invasive" and therefore, ecologically and economically harmful by some, while others consider it benign or perhaps beneficial. Z. japonica does not appear on the Federal or the Oregon invasive species or noxious weed lists. However, the State of California lists it as both an invasive and noxious weed; Washington State recently listed it as a noxious weed. We describe the management dynamics in North America with respect to these congener species and highlight the science and policies behind these decisions. In recent years, management strategies at the state level have ranged from historical protection of Z. japonica as a priority habitat in Washington to eradication in California. Oregon and British Columbia, Canada appear to have no specific policies with regard to Z. japonica. This fractured management approach contradicts efforts to conserve and protect seagrass in other regions of the US and around the world. Science must play a critical role in the assessment of Z. japonica ecology and the immediate and long-term effects of management actions. The information and recommendations provided here can serve as a basis for providing scientific data in order to develop better informed management decisions and aid in defining a uniform management strategy for Z. japonica.

TI Assessment of extracellular dehydration using saliva osmolality SO EUROPEAN JOURNAL OF APPLIED PHYSIOLOGY LA English DT Article DE Hypohydration; Hypovolemia; Volume depletion; Hydration assessment; Furosemide ID HYDRATION STATUS; FLUID; VOLUME; HYPOHYDRATION; CHILDREN; PLASMA; FUROSEMIDE; SECRETION; DIURESIS; EXERCISE AB When substantial solute losses accompany body water an isotonic hypovolemia (extracellular dehydration) results. The potential for using blood or urine to assess extracellular dehydration is generally poor, but saliva is not a simple ultra-filtrate of plasma and the autonomic regulation of salivary gland function suggests the possibility that saliva osmolality (Sosm) may afford detection of extracellular dehydration via the influence of volume-mediated factors. This study aimed to evaluate the assessment of extracellular dehydration using Sosm. In addition, two common saliva collection methods and their effects on Sosm were compared. Blood, urine, and saliva samples were collected in 24 healthy volunteers during paired euhydration and dehydration trials. Furosemide administration and 12 h fluid restriction were used to produce extracellular dehydration. Expectoration and salivette collection methods were compared in a separate group of eight euhydrated volunteers. All comparisons were made using paired t-tests. The diagnostic potential of body fluids was additionally evaluated. Dehydration (3.1 +/- A 0.5 % loss of body mass) decreased PV (-0.49 +/- A 0.12 L; -15.12 +/- A 3.94 % change), but Sosm changes were marginal (< 10 mmol/kg) and weakly correlated with changes in absolute or relative PV losses. Overall diagnostic accuracy was poor (AUC = 0.77-0.78) for all body fluids evaluated. Strong agreement was observed between Sosm methods (Expectoration: 61 +/- A 10 mmol/kg, Salivette: 61 +/- A 8 mmol/kg, p > 0.05). Extracelluar dehydration was not detectable using plasma, urine, or saliva measures. Salivette and expectoration sampling methods produced similar, consistent results for Sosm, suggesting no methodological influence on Sosm.

Predicting the temporal course of a stimulus and dynamically synchronizing the required action with the stimulus are critical for offsetting this constraint, and this prediction-synchronization capacity can be tested using visual tracking of a target with predictable motion. Although the role of temporal prediction in visual tracking is assumed, little is known of how internal predictions interact with the behavioral outcome or how changes in the cognitive state influence such interaction. We quantified and compared the predictive visual tracking performance of military volunteers before and after one night of sleep deprivation. The moment-to-moment synchronization of visual tracking during sleep deprivation deteriorated with sensitivity changes greater than 40 %. However, increased anticipatory saccades maintained the overall temporal accuracy with near zero phase error. Results suggest that acute sleep deprivation induces instability in visuomotor prediction, but there is compensatory visuomotor adaptation. Detection of these visual tracking features may aid in the identification of insufficient sleep. C1 [Tong, Jianliang; Maruta, Jun; Ghajar, Jamshid] Brain Trauma Fdn, New York, NY 10007 USA.

TI Multispectral Image Denoising With Optimized Vector Bilateral Filter SO IEEE TRANSACTIONS ON IMAGE PROCESSING LA English DT Article DE Vector bilateral filtering; Stein's unbiased risk estimator; parameter optimization ID MULTIVALUED IMAGES; NATURAL IMAGES; NOISE REMOVAL; ESTIMATORS; HYDICE AB Vector bilateral filtering has been shown to provide good tradeoff between noise removal and edge degradation when applied to multispectral/hyperspectral image denoising. It has also been demonstrated to provide dynamic range enhancement of bands that have impaired signal to noise ratios (SNRs). Typical vector bilateral filtering described in the literature does not use parameters satisfying optimality criteria. We introduce an approach for selection of the parameters of a vector bilateral filter through an optimization procedure rather than by ad hoc means. The approach is based on posing the filtering problem as one of nonlinear estimation and minimization of the Stein's unbiased risk estimate of this nonlinear estimator. Along the way, we provide a plausibility argument through an analytical example as to why vector bilateral filtering outperforms band-wise 2D bilateral filtering in enhancing SNR. Experimental results show that the optimized vector bilateral filter provides improved denoising performance on multispectral images when compared with several other approaches.

Using the National Electronic Injury Surveillance System (NEISS) database, the number of clavicle fractures presenting to a representative sample of US hospitals was retrospectively calculated and weighted estimates used to extrapolate this data to the US population. Incidence estimates were obtained using validated analyses and US census data, with sports injuries being noted and fractures stratified by sport. A total of 9428 fractures of the clavicle were reported, representing 357155 injuries in the US population over 5 years. The estimated incidence of clavicle fractures in the US presenting for emergency care is 24.4 fractures per 100000 person-years (95% confidence intervals (CI), 22.8-26.1). The peak incidence was highest between ages 10-19 years. Men were nearly 3 times as likely to sustain a clavicle fracture. Sports were a factor in 45% of all clavicle fractures. In sports-related injuries, 16% of fractures occurred from bicycling, followed by football (12%) and soccer (6%). In summary, injuries from bicycling were the most common cause of clavicle fracture, followed by contact sports. Male gender and younger age are risk factors for clavicle fractures.

TI A fatigue failure formula and a new measure of the roughness of a terrain profile SO INTERNATIONAL JOURNAL OF VEHICLE DESIGN LA English DT Article DE terrain roughness; terrain modelling AB There have been complaints that the root mean square (RMS) does not describe the roughness of terrain profiles well. Similar complaints can be made about the international roughness index (IRI) as a measurement of roughness of terrain profiles. In this paper, by using the rainflow count of the oscillations of the terrain profiles, we shall first propose a fatigue failure formula and then we shall modify it to define a new measure of roughness of terrain profiles. We shall show that this new measure can describe the roughness better than the RMS and the IRI and hence, can be used, either independently or in conjunction with RMS and IRI, as a new measure of roughness of terrain profiles.

RMS calculation requires centimetre-scale terrain elevation data; however, previous work by the authors has shown that RMS can be modelled using a 5-metre terrain profile's Fractal Dimension (FD) and Power Spectral Density (PSD) DC offset. Presented is a study of the effects of surface elevation data resolution on the model. Forty-nine ride courses were down-sampled from 30 centimetre to 0.91, 1.83, 2.74, 3.66, 4.57, 5.49, 6.40, 7.32, and 8.23 metre spacings, and an RMS model at each spacing was generated using linear regression techniques. The effects of data resolution on the RMS model were studied, and a continuous model for RMS as a function of FD and DC offset across elevation data resolutions for up to 7 metre sample spacing was developed. Results of the model's use in predicting off road military vehicle mobility are presented.

TI Grain Boundary Segregation of Interstitial and Substitutional Impurity Atoms in Alpha-Iron SO JOM LA English DT Article ID STRUCTURE-ENERGY CORRELATION; SYMMETRICAL TILT BOUNDARIES; CSL TWIST BOUNDARIES; FCC METALS; DISLOCATION NUCLEATION; COMPUTER-SIMULATION; ELECTRON-MICROSCOPE; MOLECULAR-DYNAMICS; SOLUTE SEGREGATION; CUBIC METALS AB The macroscopic behavior of polycrystalline materials is influenced by the local variation of properties caused by the presence of impurities and defects. The effect of these impurities at the atomic scale can either embrittle or strengthen grain boundaries (GBs) within. Thus, it is imperative to understand the energetics associated with segregation to design materials with desirable properties. In this study, molecular statics simulations were employed to analyze the energetics associated with the segregation of various elements (helium, hydrogen, carbon, phosphorous, and vanadium) to four aOE (c) 100 > (I 5 pound and I 13 pound GBs) and six aOE (c) 110 > (I 3 pound, I 9 pound, and I 11 pound GBs) symmetric tilt grain boundaries in alpha-Fe. This knowledge is important for designing stable interfaces in harsh environments. Simulation results show that the local atomic arrangements within the GB region and the resulting structural units have a significant influence on the magnitude of binding energies of the impurity (interstitial and substitutional) atoms. These data also suggest that the site-to-site variation of energies within a boundary is substantial. Comparing the binding energies of all 10 boundaries shows that the I 3(112) pound boundary possesses a much smaller binding energy for all interstitial and substitutional impurity atoms among the boundaries examined in this study. Additionally, based on the Rice-Wang model, our total energy calculations show that V has a significant beneficial effect on the Fe grain boundary cohesion, while P has a detrimental effect on grain boundary cohesion, much weaker than H and He. This is significant for applications where extreme environmental damage generates lattice defects and grain boundaries act as sinks for both interstitial and substitutional impurity atoms. This methodology provides us with a tool to effectively identify the local as well as the global segregation behavior that can influence the GB cohesion. C1 [Rajagopalan, M.; Solanki, K.

Gamma- T-cells have been shown to be important in postburn inflammation and wound healing; however, their cytokine phenotype at the burn wound site is unknown. C57BL/6 male mice were subjected to a major burn (25% TBSA, third degree) or sham treatment. At 3 hours, 3 days, and 7 days thereafter, skin samples were collected and subjected to dispase and trypsin digestion to isolate single cells. The cells were phenotyped and evaluated for cytokine profiles by flow cytometry. Th1 cells were defined as interferon (IFN) positive, Th2 cells were defined as interleukin (IL)-10 positive, and Th17 cells were defined as IL-17 positive. At 7 days after burn a shift toward Th2 and Th17 positive T-cells at the wound site was observed. Further analysis revealed that at 3-hour postinjury the percentage of T-cells positive for IFN, IL-10, and IL-17 were comparable between sham and burn skin samples. At 3 days and 7 days postinjury the percentage of cells positive for each cytokine increased; however, the increase was significantly greater for IL-10 and IL-17, as compared with IFN (ie, 9-20-fold vs 3-fold). Skin T-cells preferentially produced IFN (similar to 20%), which was unaffected by burn injury. These data demonstrate that burn wound T-cells are activated for enhanced cytokine production and display a shift toward a Th2 and/or Th17 phenotype. In contrast, burn wound T-cells were not activated for enhanced cytokine production.

TI Disseminated vaccine-strain varicella as initial presentation of the acquired immunodeficiency syndrome: A case report and review of the literature SO JOURNAL OF CLINICAL VIROLOGY LA English DT Review DE Varicella; Varicella vaccine; HIV-1; AIDS; Operation Enduring Freedom ID HIV-INFECTED ADULTS; KILLER T-CELLS; ZOSTER-VIRUS; CHILD; IMMUNITY AB Varicella-zoster virus (VZV) infections have declined in many industrialized countries due to vaccination with the attenuated Oka strain virus. Rare cases of severe, disseminated vaccine-strain VZV infection have occurred in the immunocompromised, although rarely in HIV-infected persons. We describe a man with previously-undiagnosed human immunodeficiency virus (HIV) infection who received VZV vaccination and subsequently presented to a combat hospital in Afghanistan with disseminated varicella, respiratory failure, and sepsis. The patient recovered with ventilator and hemodynamic support, intravenous acyclovir, and empiric antibiotic therapy. DNA sequencing detected Oka strain virus from patient blood specimens. Although safe in most populations, the VZV vaccine may cause life-threatening disease in immunocompromised patients. Improved detection of HIV infection may be useful in preventing such cases.

TI Comparison of Outcomes After Minimally Invasive Versus Open Partial Nephrectomy with Respect to Trainee Involvement Utilizing the American College of Surgeons National Surgical Quality Improvement Program SO JOURNAL OF ENDOUROLOGY LA English DT Article ID LAPAROSCOPIC PARTIAL NEPHRECTOMY; RENAL TUMORS; RESIDENT INVOLVEMENT; ACS-NSQIP AB Purpose: Complication rates of open partial nephrectomies (OPN) and minimally invasive partial nephrectomies (MIPN) have largely been reported by single and multi-institutional tertiary care centers. We sought to identify complication rates of these approaches and how they are influenced by trainee involvement utilizing an independent national surgical database. Materials and Methods: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) is a risk-adjusted data collection analyzing risk factors, demographics, and 30-day perioperative outcomes. From 2005 to 2010, we identified 1251 partial nephrectomies, of which 525 were MIPN and 726 were OPN. Results: Analysis showed a decreased risk of overall morbidity, serious morbidity, and surgical site infections (SSIs); specifically superficial SSI, urinary tract infection, and bleeding (p<0.005) in MIPN than OPN. Resident and fellow versus attending only involvement was associated with increased rates of overall, serious, and nonserious morbidity, superficial and overall SSI, bleeding, and sepsis or septic shock (p<0.05). Postgraduate year (PGY) 6 residents and fellows had a significantly higher likelihood of nonserious morbidity, organ space and overall SSI, and sepsis or septic shock compared to PGY 1-5 residents. Length of stay, which was significantly shorter with MIPN than OPN (3.2 vs 5.1 days; p<0.0001), however, was associated with longer operative times (185.7 vs 209.7 minutes, p<0.001). Conclusions: This is the first report utilizing ACS NSQIP to review surgical approaches as well as the impact of trainee involvement on clinical outcomes. The increased complication rates and cost of healthcare might be mitigated by awareness, investment in surgical simulation laboratories, and competency assessment.

TI Patient-based outcomes and quality of life after salvageable wartime extremity vascular injury SO JOURNAL OF VASCULAR SURGERY LA English DT Article ID OPERATION-ENDURING-FREEDOM; ARTERIAL INJURIES; HEALTH-STATUS; LIMB LOSS; TRAUMA; MANAGEMENT; REGISTRY; THEATER; EXPERIENCE; AMPUTATION AB Objective: To date, contemporary studies on wartime vascular trauma have focused on acute management strategies and early results, with no characterization of enduring functional limb salvage or its relation to quality of life. The objective of this study was to describe long-term, patient-based quality of life and function after extremity vascular injury (EVI). Methods: The Joint Theater Trauma Registry was queried for U.S. troops with EVI. Injury and management data was obtained and the Medical Outcomes Study Short Form 36 (SF-36) Health Survey administered after patient contact and consent. Demographic, injury, and management variables were analyzed and examined for correlation with the primary end points of favorable or unfavorable outcome defined by SF-36 Mental (MCS) or Physical Component Summary (PCS) scores of >42 or <42 (effect size >= 0.8). Results: Surveys were completed by 214 patients, who were a median age of 25 years (range, 19-52 years). The Injury Severity Score was 15.3 +/- 8.6 and the Mangled Extremity Severity Score was 5.65 +/- 1.4. Amputation-free survival was 84% at mean follow-up of 61 +/- 24 months. Overall SF-36 PCS and MCS scores were 43.0 +/- 9.2 and 46.6 +/- 12.4, respectively, with 92 respondents (43%) reporting favorable outcomes on both MCS and PCS. On multivariate analysis, older age, severe extremity injury (Mangled Extremity Severity Scores >= 7), and chronic pain were predictive of unfavorable physical outcomes (P < .05).
