TI Algae Based Hydroprocessed Fuel Use on a Marine Gas Turbine
SO JOURNAL OF ENGINEERING FOR GAS TURBINES AND POWER-TRANSACTIONS OF THE
ASME
LA English
DT Article
AB The Naval Surface Warfare Center, Carderock Division (NSWCCD) Philadelphia conducted a full scale gas turbine engine test using Rolls Royce engine models 501-K34 and 250-KS4 to assess engine performance and fuel combustion characteristics of an algae based hydroprocessed fuel. The fuel, hereafter described as alternate fuel, consisted of a 50/50 blend of NATO F-76 fuel and the algae based formulation. It is the first time that the U. S. Navy has used a nonpetroleum based fuel on a marine gas turbine. The test was conducted at the DDG 51 Land Based Engineering Site (LBES) of NSWCCD during Jan. 16-21, 2011. The alternate fuel test conducted on the 501-K34 engine consisted of seven cycles of engine operation, one using NATO F-76 fuel to develop a baseline run and six cycles using alternate fuel. Each cycle was 7 h and 20 min in duration and was composed of 27 distinct load scenarios. The total duration of the test was 44 h. The 250-KS4 engine was used as the starter mechanism for the 501-K34 engine. During the test, parameters for combustion temperature, fuel demand, fuel manifold pressure, engine start time, and operation under various load conditions were recorded. This paper discusses the results of the above test by comparing engine operation using alternate fuel to engine performance using NATO F-76 fuel. [DOI: 10.1115/1.4007339]

AB This study describes the application of porphyrin-embedded porous organosilicate materials to the adsorption of ammonia gas. Organosilicate scaffolds were synthesized through a surfactant-templating process combined with a phase separation technique. The structure offers a macro-textured scaffold to facilitate flow through the sorbent material and provide enhanced access to the available surface area provided by a combination of micro- and mesopores distributed over a range of sizes. The materials were grafted post-synthesis to provide sites for covalent immobilization of porphyrins. These porphyrins were utilized for incorporation of metal sites into the organosilicate materials. The removal of ammonia was evaluated for a number of materials incorporating copper metalloporphyrins of varied structure at varied loading levels. Results have been compared to removal of ammonia by a carbon material. Copper deuteroporphyrin IX bis-ethylene glycol provided the strongest interactions with ammonia. High loading levels of this porphyrin within the sorbent structure showed increasing evidence of stacking and did not improve the performance of the material.

AB We examine the impact of atmospheric correction, specifically aerosol model selection, on retrieval of bio-optical properties from satellite ocean color imagery. Uncertainties in retrievals of bio-optical properties (such as chlorophyll, absorption, and backscattering coefficients) from satellite ocean color imagery are related to a variety of factors, including errors associated with sensor calibration, atmospheric correction, and the bio-optical inversion algorithms. In many cases, selection of an inappropriate or erroneous aerosol model during atmospheric correction can dominate the errors in the satellite estimation of the normalized water-leaving radiances (L-n(w)), especially over turbid, coastal waters. These errors affect the downstream bio-optical properties. Here, we focus on the impact of aerosol model selection on the L-n(w) radiance estimates by comparing Aerosol Robotic Network-Ocean Color (AERONET-OC) measurements of L-n(w) and aerosol optical depth (AOD) to satellite-derived values from Moderate Resolution Imaging Spectroradiometer (MODIS) and Sea-viewing Wide Field-of-view Sensor (SeaWiFS). We also apply noise to the satellite top-of-atmosphere (TOA) radiance values in the two near-infrared (NIR) wavelengths used for atmospheric correction, to assess the effect on aerosol model selection and L-n(w) retrievals. In general, for the data sets examined, we found that as little as 1% uncertainty (noise) in the NIR TOA radiances can lead to the selection of a different pair of bounding aerosol models, thus changing L-n(w) retrievals. We also compare aerosol size fraction retrieved from AERONET and size fraction represented by aerosol models selected during atmospheric correction.

In preparation for a phase 1 clinical testing, the vaccine and the adjuvant were manufactured under current good manufacturing practice guidelines. The formulated vaccine and the adjuvant were tested for safety and/or immunogenicity in New Zealand white rabbits using a repeat dose toxicology study. The formulated vaccine and the adjuvant were found to be well tolerated by the animals. Animals injected with formulated vaccine produced strong neutralizing antibody response to all four dengue serotypes.

AB Fretting nucleation models and three-dimensional finite element analyses are used to compute the fretting fatigue life for metallic components. The models predict crack nucleation cycles and location(s). Discrete crack growth simulations provide stress intensity factor histories, with multiple, non-planar, three-dimensional cracks possible. The histories are input into crack growth rate model(s) to compute propagation cycles. The sum of fretting nucleation plus propagation cycles is the total life. Experimental fretting data, including crack nucleation location and cycles, and crack growth trajectory and propagation cycles, are used to validate the approach. Predictions for a realistic turbine blade/disk are comparable to field observations. (C) 2012 Elsevier Ltd. All rights reserved.

AB While the general catalytic mechanism of the widespread serine hydrolase superfamily has been documented extensively, much less is known about its varied modes of functional modulation within biological systems. Under oxidizing conditions, inhibition of Saccharomyces cerevisiae S-formylglutathione hydrolase (SFGH, homologous to human esterase D) activity is attributable to a cysteine (Cys-60) adjacent to its catalytic triad and approximately 8.0 angstrom away from the O gamma of the nucleophilic serine. Cys-60 is oxidized to a sulfenic acid in the structure of the Paraoxon-inhibited W197I variant (PDB 3C6B). The structural snap-shot captured an unstable reversibly oxidized state, but it remained unclear as to whether the oxidation occurred before, during, or after the reaction with the organophosphate inhibitor. To determine if the oxidation of Cys-60 was functionally linked to ester hydrolysis, we used kinetic analysis and site-directed mutagenesis in combination with X-ray crystallography. The essential nature of Cys-60 for oxidation is demonstrated by the C6OS variant, which is not inhibited by peroxide in the presence or absence of substrate. In the presence of substrate, the rate of inhibition of the WT SFGH by peroxide increases 14-fold, suggesting uncompetitive behavior linking oxidation to ester hydrolysis. Here we found one variant, H160I, which is activated by peroxide. This variant is activated at comparable rates in the presence or absence of substrate, indicating that the conserved His-160 is involved in the inhibitory mechanism linking ester hydrolysis to the oxidation of Cys-60. Copper chloride inhibition experiments show that at least two metal ions bind and inhibit both WT and H160I. A structure of the Paraoxon-inhibited W197I variant soaked with CuCl2 shows density for one metal ion per monomer at the N-terminus, and density around the Cys-60 sulfur consistent with a sulfinic acid, Cys-SO2. A Dali structural similarity search uncovered two other enzymes (Bacillus subtilis RsbQ, 1WOM and Clostridium acetobutylicum Lipase esterase, 3E0X) that contain a similar Cys adjacent to a catalytic triad. We speculate that the regulatory motif uncovered is conserved in some D-type esterases and discuss its structural similarities in the active site of human protective protein (HPP; also known as Cathepsin A).

AB The factors that influence the selection of a healthcare provider once the decision to seek care has been made can be summarized using a triad of cost, location and reputation. The goal of this study was to identify which of these factors is the primary consideration when women in urban Bo, Sierra Leone, select a healthcare provider for themselves or their children. We interviewed 1091 mothers during a household census of two neighbourhoods of Bo in April 2010. Reputation was the top consideration for about half of the women, cost was the second most common priority, and the location of the healthcare facility was the primary consideration for less than 7% of the participants. The majority of women said they would select a new provider if cost was not a barrier. Socioeconomic characteristics were not significant predictors of whether cost, location or reputation was selected as the highest-ranked consideration. This evidence for the importance of reputation in healthcare decision-making even in low-resource areas highlights the need for health systems to address issues of quality and responsiveness, and not just cost, in order to increase access to and utilization of health services.

AB The 49 type I natural pink diamonds examined exhibit color restricted to lamellae or bands oriented along {111} that are created by plastic deformation. Pink diamonds fall into two groups: (1) diamonds from Argyle in Australia and Santa Elena in Venezuela are heavily strained throughout and exhibit pink bands alternating with colorless areas, and (2) diamonds from other localities have strain localized near the discrete pink lamellae. Growth zones are highlighted by a blue cathodoluminescence (CL) and crosscut by the pink lamellae that emit yellowish-green CL that originates from the H3 center. This center probably forms by the recombination of nitrogen-related centers (A-aggregates) and vacancies mobilized by natural annealing in the Earth's mantle. Twinning is the most likely mechanism through which plastic deformation is accommodated for the two groups of diamonds. The plastic deformation creates new centers visible through spectroscopic methods, including the one responsible for the pink color, which remains unidentified. The differences in the plastic deformation features, and resulting CL properties, for the two groups might correlate to the particular geologic conditions under which the diamonds formed; those from Argyle and Santa Elena are deposits located within Proterozoic cratons, whereas most diamonds originate from Archean cratons.

TI Why the Torpedo Engagement Kill Chain Underestimates the Probability of
Kill, and How to Fix It

AB For the past several years, the U.S. Navy has assessed the performance of lightweight torpedoes (LWT) as a critical issue. The current de facto assessment is based primarily on the testing of Recoverable Exercise Torpedoes (REXTORP) and Exercise Torpedoes (EXTORP) LWTs. Because a kill never actually occurs and the REXTORPs are only partial runs, the U.S. Navy assesses LWTs by evaluating the following three events of the engagement kill chain: System Reliability (R-sys), Torpedo Reliability, and Torpedo Effectiveness. These events are assessed independently, and they are averaged to obtain probability values for the kill chain factors. These probabilities are then multiplied, and the result is reported as the Probability of Kill (P-k). This assessment is problematic because the kill does not actually occur. The grading of R-sys is linked to proficiency standards rather than to mission success. Dependencies across events in a torpedo run are not accounted for, such as an unsatisfactory torpedo grade that would otherwise allow for continuation of the kill chain and a potential mission success (e.g., target hit). Averages combine data from a wide range of tests with conditions that can significantly affect performance of the events. This paper proposes a multi-state engagement kill chain to account for such degraded events, including compensatory effects associated with functional redundancy. This would provide a holistic approach with a focus on mission success similar to the assessment of Heavyweight Torpedoes (HWT). A hypothetical example that uses this more realistic assessment indicates that the LWT R-sys and P-k are significantly higher than currently reported.

AB The present work describes the operation and simulation of a microfluidic laminar-flow mixer. Diffusive mixing takes place between a core solution containing lipids in ethanol and a sheath solution containing aqueous buffer, leading to self assembly of liposomes. Present device architecture hydrodynamically focuses the lipid solution into a cylindrical core positioned at the center of a microfluidic channel of 125 x 125-mu m(2) cross-section. Use of the device produces liposomes in the size range of 100-300 nm, with larger liposomes forming at greater ionic strength in the sheath solution and at lower lipid concentration in the core solution. Finite element simulations compute the concentration distributions of solutes at axial distances of greater than 100 channel widths. These simulations reduce computation time and enable computation at long axial distances by utilizing long hexahedral elements in the axial flow region and fine tetrahedral elements in the hydrodynamic focusing region. Present meshing technique is generally useful for simulation of long microfluidic channels and is fully implementable using comsol Multiphysics. Confocal microscopy provides experimental validation of the simulations using fluorescent solutions containing fluorescein or enhanced green fluorescent protein.

AB Bottlenose dolphins can have iron overload (that is, hemochromatosis), and managed populations of dolphins may be more susceptible to this disease than are wild dolphins. Serum iron, total iron-binding capacity (TIBC), transferrin saturation, and ferritin were measured in 181 samples from 141 dolphins in 2 managed collections and 2 free-ranging populations. Although no iron indices increased with age among free-ranging dolphins, ferritin increased with age in managed collections. Dolphins from managed collections had higher iron, ferritin, and transferrin saturation values than did free-ranging dolphins. Dolphins with high serum iron (exceeding 300 mu g/dL) were more likely to have elevated ferritin but not ceruloplasmin or haptoglobin, demonstrating that high serum levels of iron are due to a true increase in total body iron. A time-series study of 4 dolphins with hemochromatosis that were treated with phlebotomy demonstrated significant decreases in serum ferritin, iron, and TIBC between pre- and posttreatment samples; transferrin saturation initially fell but returned to prephlebotomy levels by 6 mo after treatment. Compared with those in managed collections, wild dolphins were 15 times more likely to have low serum iron (100 mu g/dL or less), and this measure was associated with lower haptoglobin. In conclusion, bottlenose dolphins in managed collections are more likely to have greater iron stores than are free-ranging dolphins. Determining why this situation occurs among some dolphin populations and not others may improve the treatment of hemochromatosis in dolphins and provide clues to causes of nonhereditary hemochromatosis in humans.

AB Oxide-bridged phenylmorphans were conceptualized as topologically distinct, structurally rigid ligands with 3-dimensional shapes that could not be appreciably modified on interaction with opioid receptors. An enantiomer of the N-phenethyl-substituted ortho-f isomer was found to have high affinity for the mu-receptor (K-i = 7 nM) and was about four times more potent than naloxone as an antagonist. In order to examine the effect of introduction of a small amount of flexibility into these molecules, we have replaced the rigid 5-membered oxide ring with a more flexible 6-membered carbon ring. Synthesis of the new N-phenethyl-substituted tricyclic N-substituted-2,3,4,9,10,10a-hexahydro-1H-1,4a-(epiminoethano)phenanthren-6- and 8-ols resulted in a two carbon-bridged relative of the f-isomers, the dihydrofuran ring was replaced by a cyclohexene ring. The carbocyclic compounds had much higher affinity and greater selectivity for the mu-receptor than the f-oxide-bridged phenylmorphans. They were also much more potent mu-antagonists, with activities comparable to naltrexone in the [S-35]GTP-gamma-S assay. Published by Elsevier Masson SAS.

AB Heavy ion, neutron, and laser experimental data are used to evaluate the effectiveness of various single event latchup (SEL) hardening strategies, including silicon-on-insulator (SOI), triple well, and guard rings. Although SOI technology is widely reported to be immune to SEL, conventional pnpn latchup can occur and has been observed in non-dielectrically isolated SOI processes. Triple well technologies are shown to be more robust against SEL than dual well technologies under all conditions used in this study, suggesting that the introduction of a deep N-well is an excellent zero-area-penalty hardening strategy. A single guard ring is shown to be sufficient for SEL immunity in the 180 nm CMOS technology investigated, and is likely sufficient for more modern CMOS technologies.
After triggering latchup in a certain pnpn region, latchup was observed to spread to neighboring pnpn regions, which then infected other more distant regions until it had spread over a total distance of 700 micrometers. We discuss the physical mechanism of this latchup domino effect and its implications for device characterization and hardness assurance.

AB Experimental evidence confirming single-event transient generation from ion strikes directly into the drain region of an InAlSb/InAs/AlGaSb high electron mobility transistor is presented. A rectifying drain alloy-buffer layer interface is shown to be responsible for the generation of single-event transients far from the active regions of the device. Charge collection in these depletion-mode devices is maximum at threshold, decreasing in both depletion and accumulation. In depletion, direct recombination of radiation-generated electrons at the drain dominates charge collection. In accumulation, the electric field in the channel strongly influences charge collection. In threshold, both source-to-channel charge injection as well as the electric field in the channel are simultaneously high, resulting in more charge collection than depletion and accumulation.

AB Neutron irradiation of a multiple bit upset sensitive bulk CMOS SRAM prior to heavy ion exposure is shown to significantly increase the number of bits upset per event observed. The displacement damage induced by the neutron exposure prior to the single event experiment is shown to have little to no impact on the performance of the SRAM. However, the neutron fluence is able to induce small changes in the resistivity of the underlying silicon of the SRAM which leads to a large change in the multiple bit upset response. From the results of this experiment, critical insight into the mechanisms behind multiple bit upsets in bulk CMOS technologies is gained.

AB 3-D histograms grading the frequency of occurrence of pulsed-laser and heavy-ion induced ASETs against their durations and amplitudes are collected and interpreted on both radiation-hardened and commercial 16-bit ADCs operated at 10 MSps. The histograms encompass traditional cross-section tabulations, modeled after digital upset scoring techniques based on counting events that exceed an arbitrary threshold; yet, they provide a more exhaustive alternative. This data representation technique offers an intuitive visual assessment of the circuit response to radiation, which helped us identify in heavy-ion test results the same trend of ASET width increase, peak decrease versus LET recently published for laser data. The method proposed in this work hinges on a database structure that allows for the definition of custom figures of merit, providing a comprehensive tool for rating radiation hardness in complex analog and mixed-signal circuits.

AB Analog Single Event Transients (ASETs) in two different shunt voltage references used in power management systems are investigated. Little has been published regarding how the dynamic parameter changes induced by external circuit design, such as time constant, damping coefficient or natural frequency affect ASET shapes. Modifications of the dynamic parameters of the circuit are measured by step response measurement. A correlation between dynamic parameters and ASET laser testing results is proposed. This study establishes the correlation between the dynamic parameters of a shunt voltage reference and ASET parameters such as pulse duration, and positive and negative amplitude.

AB Pulsed laser test results for NAND flash memories are compared with broad beam heavy ion results and also with heavy ion results obtained with the collimated Milli-Beam (TM) source. The pulsed laser measurements reported here, with smaller focused spot sizes and as a function of the incident pulse energy, serve to reconcile the previously reported inconsistencies. The Milli-Beam (TM) and pulsed laser results appear to be consistent, and differences from the broad beam heavy ion results can be explained. The results suggest that the high current SEFIs reported by us and others arise from multiple ion (or multiple photon) interactions, and are not associated with single ion strikes.

ID 2-PHOTON ABSORPTION
AB A novel RHBD technique utilizing charge sharing to mitigate single-event voltage transients in differential circuits is demonstrated experimentally. Differential charge cancellation (DCC) layout leverages the inherent common-mode rejection of differential circuits to mitigate voltage transients induced by ion strikes. A simple layout variation transforms normally single-ended error signals into common-mode signals that are mitigated by the differential signal path. This layout change maintains the matching achieved via a standard common-centroid layout but incurs negligible area penalty.
DCC layouts can provide more than an order of magnitude reduction in sensitive area across a wide range of laser energies. Evidence is presented that suggests this hardening technique will be even more effective for angled strikes and smaller device geometries.

AB The Variable Depth Bragg Peak (VDBP) method uses long-range high-energy heavy ions to measure the Single Event Effect (SEE) cross-section as a function of linear energy transfer (LET(Si)) for commercially packaged integrated circuits with sensitive volumes at unknown depths. This is done by lowering the energy of the ions incident on the device-under-test (DUT) in steps, by insertion of polyethylene degraders of increasing thickness, until the maximum event cross-section is observed, which indicates that ions with the highest average LET(Si) (at the peak of the Bragg Peak) are depositing energy in the sensitive volume. The present paper describes use of the VDBP method to test for single event latchup (SEL) in packaged parts that do and do not fail catastrophically and to certify a device by assuring that every depth in the packaged device is exposed to a fluence of ions with average LET(Si) values greater than a specified value, in this case 60 MeV/mg/cm(2).

AB We investigate total ionizing dose effects in (TID) graphene field effect transistors comprised of chemical vapor deposition grown graphene transferred onto trimethylsiloxy(TMS)-passivated SiO2Si substrates. TID exposure with a positive gate bias increases the concentration of positive oxide trapped charges near the SiO2/TMS/graphene interface making Coulomb-potential scatterer limited mobility more apparent. In particular, we observe asymmetric degradation in electron and hole mobility, the former degrading more rapidly. Consistent with the electron-hole puddle description, we observe an increase in intrinsic electron carrier density that varies linearly with the oxide trapped charge density, while the hole carrier density remains largely unaltered. These effects give rise to an increasing minimum conductivity.

AB We present the results of a radiation damage experiment on AlxGa1-xN/GaN high electron mobility transistors. The basic mechanism underlying the observed high radiation tolerance appears to be a strong internal piezoelectric field near the two-dimensional electron gas that causes scattered carriers to be reinjected.

AB This paper is dedicated to the characterization of a novel diamond microdosimeter prototype with 3D sensitive volumes produced by high energy boron implantation. Diamond has been chosen in order to further improve solid state based microdosimeter in terms of radiation hardness and tissue equivalency. IBIC measurements were undertaken to determine the charge collection efficiency map of the device. It was demonstrated that the proposed ion implantation technology allows for the formation of an array of well defined 3D SVs. A Geant4 application was developed to explain the effect of Al electrode thickness on observed anomaly in deposited energy. Specifics of the results and an update on the current status of the project is presented.

AB The calculation of the displacement damage dose (DDD) in a material is not often as straightforward as simply combining the particle fluence and the nonionizing energy loss (NIEL) but often requires a consideration of the degradation parametrics of a particular microelectronic device. This paper defines an Equivalent Displacement Damage Dose (EDDD) which is more representative of the degradation of the device. Displacement damage radiation effects in solar cells will be used to illustrate the model.

FABRICATION
AB Silicon microdosimeters for the characterisation of mixed radiation fields relevant to the space radiation environment have been under continual development at the Centre for Medical Radiation Physics for over a decade. These devices are useful for the prediction of single event upsets in microelectronics and for radiation protection of spacecraft crew. The latest development in silicon microdosimetry is a family of large-area n-SOI microdosimeters for real-time dosimetry in space radiation environments. The response of n-SOI microdosimeters to 2 MeV H and 5.5 MeV He ions has been studied to investigate their charge collection characteristics. The studies have confirmed 100% yield of functioning cells, but have also revealed a charge sharing effect due to diffusion of charge from events occurring outside the sensitive volume and an enhanced energy response due to the collection of charge created beneath the insulating layer. The use of a veto electrode aims to reduce collection of diffused charge. The effectiveness of the veto electrode has been studied via a coincidence analysis using IBIC. It has been shown that suppression of the shared events allows results in a better defined sensitive volume corresponding to the region under the core electrode where the electric field is strongest.

ID AMPLITUDE STATISTICS; PROPAGATION
AB Using simulated data with varying Rician K-factor, averaging block length (N), and sample size (P), this letter proposes and validates two new moment-based, unbiased estimators for block-averaged Rician data and presents a model for their standard errors. One estimator, (K) over cap (1,2), has standard error that varies linearly with K and requires iterative calculation. The other estimator, (K) over cap (2,4), has standard error that can be orders of magnitude larger than the estimates, but has a closed-form solution. (K) over cap (2,4) can, however, be recommended when (N <= 16, P >= 100) if real-time constraints require it. (K) over cap (1,2) is recommended otherwise.

AB In natural waters, exopolymers or extracellular polymeric substances (EPS) exuded by microorganisms interact with clay particles, resulting in the flocculation of clays and hence alteration to the properties of suspended cohesive sediments. To investigate and further understand how neutral EPS affect cohesive sediment transport and the final sediment yield, an experimental study was conducted on laboratory-prepared clay and guar gum (used as an analog for neutral EPS) suspensions to characterize EPS-induced flocculation and the settling velocity of resultant flocs. Four different clays consisting of kaolinite, illite, Ca-montmorillonite, and Na-montmorillonite were studied to examine the influence of different layer charges on clay flocculation induced by neutral EPS. Floc size was determined by a laser particle size analyzer, and settling velocity estimated by analyzing the time-series floc settling images captured by an optical microscope. Results indicate that neutral EPS promote clay-EPS flocculation for all four clays with the particle/floc size significantly increased from similar to 0.1-60 mu m to as large as similar to 600 mu m. Clays' layer charge has a profound influence on the clayEPS flocculation. With the same floc size, the settling velocity of clay-EPS flocs is typically smaller than that of pure clay flocs, which is attributed to the reduced density of flocs caused by the EPS. However, for flocs of the same composition (e.g. pure clay or hybrid clay-EPS mixture), the settling velocity increases with size. The fractal dimension of these clay-EPS flocs estimated from settling velocity ranges from 1.39 to 1.47, which are smaller than that of pure clay flocs, indicating that these flocs are less compacted than the pure clay flocs.

AB A new, fully conserved minimal adjustment scheme with temperature and salinity (T, S) coherency is presented for eliminating false static instability generated from analyzing and assimilating stable ocean (T, S) profiles data, that is, from generalized averaging over purely observed data (data analysis) or over modeled/observed data (data assimilation). This approach consists of a variational method with (a) fully (heat, salt, and potential energy) conserved conditions, (b) minimal adjustment, and (c) (T, S) coherency. Comparison with three existing schemes (minimal adjustment, conserved minimal adjustment, and convective adjustment) using observational profiles and a simple one-dimensional ocean mixed layer model shows the superiority of this new scheme.

AB BACKGROUND: The Armed Services Blood Program (ASBP) provides the farthest-reaching blood supply in the world. This article provides statistics and a review of blood operations in support of combat casualty care during the last 10 years. It also outlines changes in blood doctrine in support of combat casualty care.
METHODS: This is a descriptive overview and review of blood product use and transfusions used by ASBP personnel to support combat operations in Iraq and Afghanistan between October 2001 and November 2011.
RESULTS: The ASBP initiated major changes in blood availability and age of blood in theater. In support of data published by physicians in theater, showing improved patient survival when a higher ratio of fresh frozen plasma and red blood cells (RBCs) is achieved, plus the use of platelets, the ASBP increased availability of plasma and established platelet collection facilities in theater. New capabilities included emergency collection of apheresis platelets in the battlefield, availability and transfusion of deglycerolized red cells, rapid diagnostic donor screening, and a new modular blood detachment. Forward surgical facilities that were at one time limited to a blood inventory consisting of RBCs now have a complete arsenal of products at their fingertips that may include fresher RBCs, fresh frozen plasma, cryoprecipitate, and platelets. A number of clinical practice guidelines are in place to address these processes. Changes in blood doctrine were made to support new combat casualty care and damage-control resuscitation initiatives.
CONCLUSION: Despite the challenges of war in two theaters of operation, a number of improvements and changes to blood policy have been developed during the last 10 years to support combat casualty care. The nature of medical care in combat operations will continue to be dynamic and constantly evolving. The ASBP needs to be prepared to meet future challenges.

AB In the late 1990s, a Department of Defense subcommittee screened more than 100 civilian trauma centers according to the number of admissions, percentage of penetrating trauma, and institutional interest in relation to the specific training missions of each of the three service branches. By the end of 2001, the Army started a program at University of Miami/Ryder Trauma Center, the Navy began a similar program at University of Southern California/Los Angeles County Medical Center, and the Air Force initiated three Centers for the Sustainment of Trauma and Readiness Skills (C-STARS) at busy academic medical centers: R. Adams Cowley Shock Trauma Center at the University of Maryland (C-STARS Baltimore), Saint Louis University (C-STARS St. Louis), and The University Hospital/University of Cincinnati (C-STARS Cincinnati). Each center focuses on three key areas, didactic training, state-of-the-art simulation and expeditionary equipment training, as well as actual clinical experience in the acute management of trauma patients. Each is integral to delivering lifesaving combat casualty care in theater. Initially, there were growing pains and the struggle to develop an effective curriculum in a short period. With the foresight of each trauma training center director and a dynamic exchange of information with civilian trauma leaders and frontline war fighters, there has been a continuous evolution and improvement of each center's curriculum. Now, it is clear that the longest military conflict in US history and the first of the 21st century has led to numerous innovations in cutting edge trauma training on a comprehensive array of topics. This report provides an overview of the decade-long evolutionary process in providing the highest-quality medical care for our injured heroes. (J Trauma Acute Care Surg. 2012;73: S483-S489.

AB Limited prospective studies exist that evaluate the mental health status of military health care professionals who have deployed. This study used prospective data from the Millennium Cohort Study with longitudinal analysis techniques to examine whether health care professionals deployed in support of the operations in Iraq and Afghanistan were more likely to screen positive for new-onset posttraumatic stress disorder (PTSD) or depression after deployment than individuals from other occupations. Of 65,108 subjects included, 9,371 (14.4%) reported working as health care professionals. The rates of new positive screens for PTSD or depression were similar for those in health care occupations (4.7% and 4.3%) compared with those in other occupations (4.6% and 3.9%) for the first and second follow-up, respectively. Among military personnel deployed with combat experience, health care professionals did not have increased odds for new-onset PTSD or depression over time. Among deployed health care professionals, combat experience significantly increased the odds: adjusted odds ratio = 2.01; 95% confidence interval [1.06, 3.83] for new-onset PTSD or depression. These results suggest that combat experience, not features specific to being a health care professional, was the key exposure explaining the development of these outcomes.

AB High resolution infrared imagery of breaking waves in a wave-tank free of wind shear or current reveals the production of a "streaky," quasi-periodic thermal pattern produced during the breaking process. The streaks, or elongated patterns of warm and cold fluid, are found to form only when surface turbulence is present before wave breaking occurs. This suggests that wave-turbulence interaction is one mechanism that can lead to streak formation in breaking wave systems. More specifically, the streaky structures observed in these experiments may be caused by an intense, rapid tilting, and stretching of pre-existing vertical vorticity by the Stokes drift generated at or near the breaking wave crests, thereby generating a coherent system of counter-rotating vortices. We attempt to relate our observations to the recent theory of Teixeira and Belcher [J. Fluid Mech. 458, 229-267 (2002)]. Some properties of the streaks, such as the dependence of their lifetimes and spanwise scale on wave amplitude, are presented. (C) 2012 American Institute of Physics.

AB Relatively few studies have been carried out as to the conditions leading to the formation of monsoon depressions in the western North Pacific. Two monsoon depression formations during July 2007 were analyzed using ECMWF analyses and satellite observations. Wave-activity flux calculations indicated that cross-equatorial flow from the Southern Hemisphere played an important role in the formation of these monsoon depressions. A new conceptual model of monsoon depression formation in the western North Pacific is proposed that includes three southerly airstreams in the Southern Hemisphere that lead to cross-equatorial flows into the Northern Hemisphere. Examination of 44 monsoon depressions from April to December 2009 confirms the critical role of these cross-equatorial flows in monsoon depression formation. All of the monsoon depressions in the 2009 sample for which formation conditions could be established had at least one of three possible airstreams that interacted with a confluent region and, thus, may be a necessary condition for monsoon depression formation. This conceptual model of monsoon depression formation was further confirmed by means of wave-activity flux calculations and backward trajectory ensembles for the 2009 cases.

AB Semiconductor nanocrystals, or quantum dots (QDs), are one of the most widely utilized nanomaterials for biological applications. Their cumulative physicochemical and optical properties are both unique among nanomaterials and highly advantageous. In particular, Forster resonance energy transfer (FRET) has been widely utilized as a spectroscopic tool with QDs, whether for characterizing QD bioconjugates as a "molecular ruler" or for modulating QD luminescence "on" and "off' in biosensing configurations. Here, we investigate the assembly and utility of a new "concentric" FRET relay that comprises a central QD conjugated with multiple copies of two different peptides, each labeled with one of two fluorescent dyes, Alexa Fluor 555 (A555) or Alexa Fluor 647 (A647). Energy transfer occurs from the QD to the A555 (FRET1) then to the A647 (FRET2) and, to a lesser extent, directly from the QD to the A647 (FRET3). We show that such an arrangement can provide insight into the interfacial distribution of peptides assembled to the QD and can further be utilized for sensing proteolytic activity. In the latter, progress curves for digestion of the assembled peptides by two prototypical proteases, trypsin and chymotrypsin, were measured from the relative QD, A555 and A647 PL contributions, and used to extract Michaelis-Menten kinetic parameters. We further show that the concentric FRET relay, as a single nanoparticle vector, can track the tryptic activation of a proenzyme, chymotrypsinogen, to active chymotrypsin. The concentric FRET relay is thus a potentially powerful tool for the characterization of QD bioconjugates and multiplexed sensing of coupled biological activity.

AB The state of the California Current System (CCS) since spring 2011 has evolved in response to dissipation of La Nina through spring and summer, resurgence of cooler La Nina conditions in fall and winter, and finally a transition towards ENSO-neutral conditions in spring 2012. The resurgence of La Nina was uneven, however, as indicated by variable responses in broad climate indices such as the Pacific Decadal Oscillation and the multi-variate ENSO index, and by latitudinal variability in the timing, strength, and duration of upwelling relative to climatological means. Across the CCS, various measures of ecosystem productivity exhibited a general decline in 2011 relative to 2010, but the magnitude of these declines varied substantially among taxa. Available observations indicate regional variability in climate forcing and ecosystem responses throughout the CCS, continuing a pattern that has emerged with increasing clarity over the past several years. In 2011-12, regional variability was again a consequence of southern regions exhibiting a relatively mild response to climate forcing, in this case tending towards climatological means, while northern regions showed somewhat greater effects of delayed or weaker-than-normal upwelling. In addition to the effects of local and basin-scale forcing, long-term observations off southern California show declines in dissolved oxygen and increases in nutrient concentrations in waters below the mixed layer, trends that are consistent with recent predictions of how global warming will affect the characteristics of upwelling source waters in the CCS. Such trends must be accounted for more comprehensively in ongoing assessment of the state of the California Current and its responses to environmental forcing. At the time of writing, tropical conditions are ENSO neutral and forecast to transition into El Nino in late 2012. This, combined with unusually high abundances of diverse gelatinous taxa throughout much of the CCS during spring 2012, suggests that the ongoing evolution of the state of the California Current might take a particularly unusual path in the coming year.

AB Two series of boronium-cation-based ionic liquids were prepared and fully characterized by 1H, 13C, and 11B NMR and infrared spectroscopy, differential scanning calorimetry (DSC), and elemental analysis. The structure of bis(1-methyl-1H-imidazole-3-yl)dihydroboronium dicyanoborohydride (5?a) was determined by single-crystal X-ray diffraction. The densities of these ionic liquids range from 1.05 to 1.28 g?cm-3, and the heats of formation, predicted on the basis of Gaussian 03 calculations, fall between -164.6 and 430.5 kJ?mol-1. Compound 5?b, bis(1-allyl-1H-imidazole-3-yl)dihydroboronium dicyanoborohydride, exhibits the lowest viscosity (35 mPa?s) and shortest ignition-delay time (14 ms) in combination with 100?% HNO3.

TI Simulation Of Quitting Smoking In The Military Shows Higher Lifetime
Medical Spending More Than Offset By Productivity Gains
SO HEALTH AFFAIRS
LA English
DT Article
ID WEIGHT; RISK; OVERWEIGHT; CESSATION
AB Despite the documented benefits of quitting smoking, studies have found that smokers who quit may have higher lifetime medical costs, in part because of increased risk for medical conditions, such as type 2 diabetes, brought on by associated weight gain. Using a simulation model and data on 612,332 adult smokers in the US Department of Defense's TRICARE Prime health plan in 2008, we estimated that cessation accompanied by weight gain would increase average life expectancy by 3.7 years, and that the average lifetime reduction in medical expenditures from improved health ($5,600) would be offset by additional expenditures resulting from prolonged life ($7,300). Results varied by age and sex: For females ages 18-44 at time of cessation, there would be net savings of $1,200 despite additional medical expenditures from prolonged life. Avoidance of weight gain after quitting smoking would increase average life expectancy by four additional months and reduce mean extra spending resulting from prolonged life by $700. Overall, the average net lifetime health care cost increase of $1,700 or less per ex-smoker would be modest and, for employed people, more than offset by even one year's worth of productivity gains. These results boost the case for smoking cessation programs in the military in particular, along with not selling cigarettes in commissaries or at reduced prices.

AB Experiments with various wire loads from midatomic-number wires, which were performed on the university-scale 1-MA Zebra generator at the University of Nevada, Reno, during the last few years, are analyzed to assess the highest electron temperature reached. In particular, the results from experiments with planar wire arrays (PWAs) were considered. Load materials from mid-atomic-number such as stainless steel, Alumel, Cu, brass, Mo, and up to Ag were used to generate L-shell plasmas and to study plasma parameters. Though the full diagnostic set was utilized, the main focus was on X-ray spectroscopic data and on the non-local thermodynamic equilibrium kinetic modeling. As a result, the scaling of the maximum T-e with the load material atomic number is presented for the first time in the range from Fe to Ag for L-shell plasmas from PWAs. The highest values of the electron temperature in L-shell plasmas, which are estimated from the modeling, were from both Ag PWAs and X-pinches. This work is important for the development of efficient X-ray radiators on university-scale Z-pinch generators.

AB The fabrication of a unilateral device to treat microstomia after trauma is presented. Maximum opening was recorded before treatment. A dual arch impression that captured the dentition and commissure on the affected side was made with vinyl polysiloxane (VPS) impression material. A 1 mm vacuum formed template (VFT) was fabricated over the maxillary dentition, and a 2 mm VFT was fabricated around the commissure. A 0.9 mm (0.036 '') stainless steel wire was attached with acrylic resin to both templates in order to apply a constant force to the commissure. The use of a helix in the wire allowed for flexibility and adjustment of the retractor. The patient was instructed to wear the retractor for 6 hours per day, and, during a 10-week period, the maximum opening increased from 30 mm to 45 mm. ( J Prosthet Dent 2012;108:398-400)

AB Published annual-to-decadal-resolution stalagmite delta 18O records since AD 900 from six caves (Dongge, Furong, Heshang, Buddha, Shihua and Wanxiang) in China were analyzed to detect temporal and spatial variability of the East Asian Summer Monsoon strength, which strongly affects wet/dry conditions in eastern China. The empirical mode decomposition method was used to obtain trends of the six cave records. After the base trend was determined, delta 18O anomalies of each record were computed by subtracting the base trend. Mean delta 18O anomaly values of the detrended time series for each cave record were calculated for four periods: (i) Medieval Warm Period (MWP; AD 9001250): (ii) Little Ice Age phase 1 (LIA-1; AD 12501550); (iii) Little Ice Age phase 2 (LIA-2; AD 15501850); and (iv) modern period (MD; AD 18502000). From these anomalies, the temporal and spatial variability of wet/dry conditions has been identified. Positive values of the mean delta 18O anomalies indicating drier conditions appeared in the lower Yangtze River Drainage Area and Southeast Coast Area during MD-1, LIA-1 and MWP, whereas negative values existed in north, south and Yangtze areas of eastern China during LIA-2. The results agree with the dryness/wetness index reconstructed by Chinese historic records in general. These results illustrate that wet and dry conditions in different regions of eastern China could be opposite under monsoon influence, so that no single speleothem delta 18O record could represent the monsoonal climate in this vast region. Climatic patterns in the monsoonal region can be either a combination of warm/wet and cold/dry or a combination of cold/wet and warm/dry on annual-to-centennial scales. A 128-year periodic cycle exists in all six cave records, whereas 64-year (possibly a harmonic of 128-year periodicity) and 42-year periodicities appear in Shihua, Heshang and Dongge records. These cycles may reflect the influence of solar activity on the East Asian Summer Monsoon. Copyright (c) 2012 John Wiley & Sons, Ltd.

SYSTEM; CONVECTIVE SCHEME; MOIST CONVECTION; FIELD EXPERIMENT
AB The sensitivity of tropical cyclogenesis and subsequent intensification is explored by applying small perturbations to the initial state in the presence of organized mesoscale convection and synoptic-scale forcing using the adjoint and tangent linear models for the Coupled Ocean Atmosphere Mesoscale Prediction System (COAMPS). The forward, adjoint, and tangent linear models are used to compare and contrast predictability characteristics for the disturbance that became Typhoon Nuri and a nondeveloping organized convective cluster in the western Pacific during The Observing System Research and Predictability Experiment (THORPEX) Pacific Asian Regional Campaign (T-PARC) and the Tropical Cyclone Structure-2008 (TCS-08) experiments.
The adjoint diagnostics indicate that the intensity (e.g., maximum surface wind speed, minimum surface pressure) of a tropical disturbance is very sensitive to perturbations in the moisture and temperature fields and to a lesser degree the wind fields. The highest-resolution adjoint simulations (grid increment of 13 km) indicate that the most efficient intensification is through moistening in the lower and middle levels and heating in banded regions that are coincident with vorticity maxima in the initial state. Optimal adjoint perturbations exhibit rapid growth for the Nun case and only modest growth for the nondeveloping system. The adjoint results suggest that Nun was near the threshold for development, indicative of low predictability. The low-level sensitivity maximum and tendency for optimal perturbation growth to extend vertically through the troposphere are consistent with a "bottom up" development process of TC genesis, although a secondary midlevel sensitivity maximum is present as well. Growth originates at small scales and projects onto the scale of the vortex, a manifestation of perturbations that project onto organized convection embedded in regions of cyclonic vorticity.

AB The impact of gravity waves on marine stratocumulus is investigated using a large-eddy simulation model initialized with sounding profiles compositecl from the Variability of American Monsoon Systems (VAMOS) Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-Rex) aircraft measurements and forced by convergence or divergence that mimics mesoscale diurnal, semidiurnal, and quarter-diurnal wave;. These simulations suggest that wave-induced vertical motion can dramatically modify the cloud albedo and morphology through nonlinear cloud-aerosol-precipitation-circulation-turbulence feedback.
In general, wave-induced ascent tends to increase the liquid water path (LWP) and the cloud albedo. With a proper aerosol number concentration, the increase in the LWP leads to enhanced precipitation, which triggers or strengthens mesoscale circulations in the boundary layer and accelerates cloud cellularization. Precipitation also tends to create a decoupling structure by weakening the turbulence in the subcloud layer. Wave-induced descent decreases the cloud albedo by dissipating clouds and forcing a transition from overcast to scattered clouds or from closed to open cells. The overall effect of gravity waves on the cloud variability and morphology depends on the cloud property, aerosol concentration, and wave characteristics. In several simulations, a transition from closed to open cells occurs under the influence of gravity waves, implying that some of the pockets of clouds (POCs) observed over open oceans may be related to gravity wave activities.

AB A super-elastic collision is an unusual process in which some mechanism causes the kinetic energy of the system to increase. Most studies have focused on solid-like objects, and have rarely considered gases or liquids, as the collision of these is primarily a mixing process. However, magnetized plasmoids are different from ordinary gases-as cross-field diffusion is effectively prohibited-but it remains unclear how they behave during a collision. Here we present a comprehensive picture of a unique collision between two coronal mass ejections in the heliosphere, which are the largest magnetized plasmoids erupting from the Sun. Our analysis reveals that these two magnetized plasmoids collided as if they were solid-like objects, with a likelihood of 73% that the collision was super-elastic. The total kinetic energy of the plasmoid system increased by about 6.6% through the collision, significantly influencing its dynamics.

Each of the salts were characterized chemically, thermally, morphologically, as well as with respect to destructive stimuli (impact, electrostatic discharge, friction, thermal). These salts show promise as propellant ingredient additives, and in particular, the bis-triaminoguanidinium salt of N4BIM displays excellent burn rate and combustion behavior. Our combustion studies have shown that TAGN4BIM displays a fast burning rate and has the lowest pressure dependence exponent yet measured for a triaminoguanidinium salt.

AB In 2005, sulphadoxine-pyrimethamine (SP) became the drug of choice for intermittent preventive treatment of Plasmodium falciparum malaria in pregnancy (IPTp) in Ghana. Reports suggest the use of SP by others to treat uncomplicated malaria. Because of the increased use of SP, the prevalence of mutations in the genes, dihydrofolate reductase (dhfr), and dihydropteroate synthetase (dhps), linked to SP resistance in P. falciparum were determined. Blood samples from 945 children with uncomplicated malaria collected at nine sites from 2003 to 2010 were analyzed using polymerase chain reaction and restriction fragment length polymorphism. Prevalence of the dhfr triple and dhfr plus dhps quadruple mutations showed significant increase in trend from 2003 to 2010 (chi(2) = 18.78, P < 0.001, chi(2) = 15.11, P < 0.001, respectively). For dhps double mutant G437 + E540 the prevalence was low (1.12%) caused by the very low prevalence of E540. Our findings show the wide use of SP in Ghana and therefore its use for IPTp needs to be closely monitored.

ID CHILDREN; EPIDEMIOLOGY
AB Objective: To determine the current public health burden of injuries due to caustic ingestion in children.
Design: The 2009 Kids' Inpatient Database provides data on a sample of all pediatric hospital discharges in the United States during that year. Children with caustic ingestion injuries requiring hospitalization were identified by corresponding codes from the International Classification of Diseases, Ninth Revision. Database analysis generated national estimates of summary statistics.
Setting: A national database.
Patients: Representative sample of all hospital discharge data on patients 18 years or younger.
Main Outcome Measures: Public health burden related to caustic injury, including potential factors related to admission outcome, the necessity of a procedure during the admission, admission length of stay, and total charges for the admission.
Results: We estimated the prevalence of pediatric caustic ingestion injuries requiring hospitalization in the United States in 2009 to be 807 (95% CI, 731-882) children. The annual economic burden was estimated at $22 900 000 (95% CI, $15 400 000-$30 400 000) in total hospital charges. The mean charge per patient was estimated at $28 860 (95% CI, $19 799-$37 922) with a median of $9848. The mean length of admission was 4.13 (95% CI, 3.22-5.03) days with a median of 2 days. Among the 807 patients, 45.3% underwent esophagoscopy, and those admitted to teaching hospitals were more likely to undergo a procedure during their stay (P =. 02). Logistic regression models suggested significant median income (P <.001) and sex (P <.001) variations.
Conclusions: The current public health burden of pediatric caustic ingestion injuries may be less than commonly cited. This finding supports the notion that legislative efforts have been successful. Despite these successes, these injuries continue to impose a significant burden on health care resources. Arch Otolaryngol Head Neck Surg. 2012;138(12):1111-1115

AB We present an online catalog containing spectra and supporting information for cataclysmic variables that have been observed with the Far-Ultraviolet Spectroscopic Explorer (FUSE). For each object in the catalog we list some of the basic system parameters such as (R.A., decl.), period, inclination, and white dwarf mass, as well as information on the available FUSE spectra: data ID, observation date and time, and exposure time. In addition, we provide parameters needed for the analysis of the FUSE spectra such as the reddening E(B - V), distance, and state (high, low, intermediate) of the system at the time it was observed. For some of these spectra we have carried out model fits to the continuum with synthetic stellar and/or disk spectra using the codes TLUSTY and SYNSPEC. We provide the parameters obtained from these model fits; this includes the white dwarf temperature, gravity, projected rotational velocity, and elemental abundances of C, Si, S, and N, together with the disk mass accretion rate, the resulting inclination, and model-derived distance (when unknown). For each object one or more figures are provided (as gif files) with line identification and model fit(s) when available. The FUSE spectra and the synthetic spectra are directly available for download as ASCII tables. References are provided for each object, as well as for the model fits. In this article we present 36 objects, and additional ones will be added to the online catalog in the future. In addition to cataclysmic variables, we also include a few related objects, such as a wind-accreting white dwarf, a pre-cataclysmic variable, and some symbiotics.

AB Evidence continues to accumulate showing the benefits of breastfeeding to infants, mothers, and society as a whole. However, breastfeeding success rates nationwide have consistently fallen short of recommendations set forth by the American Academy of Pediatrics. There are several potential barriers to successful breastfeeding, and many of these could be magnified in the demanding careers of military members and their families. We surveyed 254 women at a regional military medical facility, both active duty members and dependents of active duty members, regarding their ability to successfully breastfeed their infants. We found that American Academy of Pediatrics target goals in this population as a whole were indeed nearly met at this facility, but also found that active duty members and those who encountered military-related difficulty fell well short of these goals. These findings suggest potential barriers to breastfeeding success that warrant further study from the U.S. Department of Defense.

AB The home space for optimal control is a Sobolev space. The home space for pseudospectral theory is also a Sobolev space. It thus seems natural to combine pseudospectral theory with optimal control theory and construct "pseudospectral optimal control theory", a term coined by Ross. In this paper, we review key theoretical results in pseudospectral optimal control that have proven to be critical for a successful flight. Implementation details of flight demonstrations onboard NASA spacecraft are discussed along with emerging trends and techniques in both theory and practice. The 2011 launch of pseudospectral optimal control in embedded platforms is changing the way in which we see solutions to challenging control problems in aerospace and autonomous systems.

AB Spin-orbit coupling is often described in an approach known as "the MacDonald torque", which has long become the textbook standard due to its apparent simplicity. Within this method, a concise expression for the additional tidal potential, derived by MacDonald (Rev Geophys 2:467-541, 1994), is combined with a convenient assumption that the quality factor Q is frequency-independent (or, equivalently, that the geometric lag angle is constant in time). This makes the treatment unphysical because MacDonald's derivation of the said formula was, very implicitly, based on keeping the time lag frequency-independent, which is equivalent to setting Q scale as the inverse tidal frequency. This contradiction requires the entire MacDonald treatment of both non-resonant and resonant rotation to be rewritten. The non-resonant case was reconsidered by Efroimsky and Williams (Cel Mech Dyn Astron 104:257-289, 2009), in application to spin modes distant from the major commensurabilities. In the current paper, we continue this work by introducing the necessary alterations into the MacDonald-torque-based model of falling into a 1-to-1 resonance. (The original version of this model was offered by Goldreich (Astron J 71:1-7, 1996). Although the MacDonald torque, both in its original formulation and in its corrected version, is incompatible with realistic rheologies of minerals and mantles, it remains a useful toy model, which enables one to obtain, in some situations, qualitatively meaningful results without resorting to the more rigorous (and complicated) theory of Darwin and Kaula. We first address this simplified model in application to an oblate primary body, with tides raised on it by an orbiting zero-inclination secondary. (Here the role of the tidally-perturbed primary can be played by a satellite, the perturbing secondary being its host planet. A planet may as well be the perturbed primary, its host star acting as the tide-raising secondary). We then extend the model to a triaxial primary body experiencing both a tidal and a permanent-figure torque exerted by an orbiting secondary. We consider the effect of the triaxiality on both circulating and librating rotation near the synchronous state. Circulating rotation may evolve toward the libration region or toward a spin faster than synchronous (the so-called pseudosynchronous spin). Which behaviour depends on the orbit eccentricity, the triaxial figure of the primary, and the mass ratio of the secondary and primary bodies. The spin evolution will always stall for the oblate case. For libration with a small amplitude, expressions are derived for the libration frequency, damping rate, and average orientation. Importantly, the stability of pseudosynchronous spin hinges upon the dissipation model. Makarove and Efroimsky (Astrophys J, 2012) have found that a more realistic tidal dissipation model than the corrected MacDonald torque makes pseudosynchronous spin unstable. Besides, for a sufficiently large triaxiality, pseudosynchronism is impossible, no matter what dissipation model is used.

AB While flow across long tube bundles is considered classical data, pin-fin arrays made up of short tubes have become a growing topic of interest for use in cooling gas turbine airfoils. Data from the literature indicate that decreasing streamwise spacing increases heat transfer in pin-fin arrays; however, the specific mechanism that causes increased heat transfer coefficients remains unknown. The present work makes use of time-resolved PIV to quantify the effects of streamwise spacing on the turbulent near wake throughout various pin-fin array spacings. Specifically, proper orthogonal decomposition was used to separate the (quasi-) periodic motion from vortex shedding and the random motion from turbulent eddies. Reynolds number flow conditions of 3.0 x 10(3) and 2.0 x 10(4), based on pin-fin diameter and velocity at the minimum flow area, were considered. Streamwise spacing was varied from 3.46 pin diameters to 1.73 pin diameters while the pin-fin height-to-diameter ratio was unity and the spanwise spacing was held constant at two diameters. Results indicated that (quasi-) periodic motions were attenuated at closer streamwise spacings while the level of random motions was not strongly dependent on pin-fin spacing. This trend was observed at both Reynolds number conditions considered. Because closer spacings exhibit higher heat transfer levels, the present results imply that periodic motions may not contribute to heat transfer, although further experimentation is required.

AB Active imaging can provide significantly larger signal margins in the millimeter-wave spectral region than passive imaging, especially indoors-an important application for which there is no cold sky illumination. However, coherent effects, such as speckle, negate much of this advantage by destroying image clarity and target recognition. Moreover, active imaging demonstrations often use strategically chosen target orientations to optimally reflect power from the active illuminator back to the imaging receiver. In this paper we will discuss and show experimental results for a new active imaging approach that largely eliminates coherent effects and the need for optimized target orientation. The work described uses a synthesized harmonic multiplier chain to drive a 5 W extended interaction klystron at 218.4 GHz, a mechanical mode mixer to illuminate and modulate many modes, and a heterodyne receiver coupled into a 60 cm scanning mirror. Large signal margins were obtained in this similar to 50 m range work, showing paths to imaging at similar to 1 km, imaging with considerably less powerful illuminators, and the use of focal plane arrays.

AB The objective of this study is to examine the Fluid Structure Interaction (FSI) effect on transient dynamic response and failure of sandwich composite structures under impact loading. The primary sandwich composite used in this study consisted of a 6.35 mm balsa core and a multi-ply symmetrical plain weave 6 oz E-glass skin. Both clamped sandwich composite plates and beams were studied using a uniquely designed vertical drop-weight testing machine. There were three impact conditions on which these experiments focused. The first of these conditions was completely dry (or air surrounded) testing. The second condition was completely water submerged. The final condition was also a water submerged test with air support at the backside of the plates. The tests were conducted sequentially, progressing from a low to high drop height to determine the onset and spread of damage to the sandwich composite when impacted with the test machine. The study showed the FSI effect on sandwich composite structures is very critical such that impact force, strain response, and damage size are generally much greater with FSI under the same impact condition. As a result, damage initiates at much lower impact energy conditions with the effect of FSI. Neglecting to account for FSI effects on sandwich composite structures results in very non-conservative analysis and design. Additionally, it was observed that the damage location changed for sandwich composite beams with the effect of FSI.

AB Little data exist regarding the acute assessment of blast concussion and the course of recovery in the combat zone, as most research has examined service members long after they have returned home. This manuscript examined a case series of 377 service members seen for acute concussion evaluation following medical evacuation from the battlefield in Helmand Province, Afghanistan. Of these, 111 were assessed for concussion prior to their return to the continental USA for other severe physical injuries. Of the remainder, and when comparing those who returned to duty (RTD)/recovered from concussion in the combat zone and those who did not, data indicate that those who did not RTD were older and were more likely to endorse symptoms of combat stress. Quicker recovery times were associated with less severe headaches and fewer acute symptoms at the time of injury as well as the absence of combat stress reaction. Variables that were not associated with RTD and/or recovery were Military Acute Concussion Evaluation (MACE) cognitive scores and whether or not individuals suffered loss of consciousness. While MACE scores were not associated with recovery, they were deemed clinically useful as a part of a serial concussion evaluation if the initial MACE was given within 6 h of the blast. Implications for battlefield concussion assessment and management as well as future research directions are discussed.

ID SNAPPING SCAPULA SYNDROME; MANAGEMENT; RESECTION; ANATOMY
AB Purpose: The purpose of this study was to assess the efficacy of arthroscopic scapulothoracic bursectomy in patients with snapping scapula syndrome with a minimum of 2 years' follow-up. Methods: In this institutional review board-approved retrospective study, 23 shoulders in 21 consecutive patients were identified that had undergone arthroscopic treatment of snapping scapula syndrome. Each patient described mechanical symptoms with failure of nonsurgical modalities and reported symptomatic relief from a local anesthetic injection before surgical intervention. Preoperative and postoperative pain and functioning levels were assessed with the American Shoulder and Elbow Surgeons (ASES), QuickDASH (shortened version of the Disabilities of the Arm, Shoulder and Hand questionnaire), and Single Assessment Numeric Evaluation (SANE) shoulder scores, and patient satisfaction was recorded on a 10-point visual analog scale. Univariate and paired t tests were used for data analysis. Significance was established at P <= .05. Results: The mean age at the time of surgery was 33 years (SD, 14 years). A scapulothoracic bursectomy alone was performed in 2 shoulders, and the remaining 21 shoulders underwent both bursectomy and scapuloplasty of the superomedial or inferomedial scapular border. At a mean follow-up of 2.5 years (SD, 0.57 years), a significant improvement in the median ASES score was noted, from 53 points (range, 17 to 83 points) preoperatively to 73 points (range, 32 to 100 points) postoperatively (P = .001). The mean SANE and QuickDASH scores at follow-up were 73 (SD, 27) and 35 (SD, 30), respectively. Overall, median patient satisfaction with surgical outcome was 6 of 10 (range, 1 to 10). Of the shoulders, 3 (13%) underwent revision for persistent scapulothoracic pain. Conclusions: Snapping scapula syndrome can be a debilitating disorder. Although significant pain and functional improvement can be expected after arthroscopic bursectomy and scapuloplasty, the average postoperative ASES and SANE scores remain lower than expected. Level of Evidence: Level IV, retrospective case series.

AB The effect of preloading on thin composite plates subjected to underwater explosive loading has been studied through computational simulations. In this study the effects of three types of in plane preloading are considered: (1) directly applied compression, (2) indirectly applied compression, and (3) directly applied tension. The effects of the preloading conditions are assessed using the plate center point deflection, material damage, and delamination evolution. The results show that for thin composite plates subjected to underwater shock loading conditions there is a minimal effect of preload on the response of the plates or the amount of damage and delamination sustained.

AB The stopbands of a cascaded integrator-comb (CIC) decimation filter are ordinarily very narrow, as each results from a single multiple zero. Here response sharpening with a Chebyshev polynomial, using a previously reported CIC variant, separates each such multiple zero into an equiripple stopband. By trading unneeded depth at stopband center for improved depth at the stopband edge, the latter depth improves by some 6(N-1) dB in an Nth-order system. Increased computational complexity is modest: a few low-speed additions and multiplications by small integer coefficients that can often be chosen as powers of two. Alternatively, parameters can be configured to replace the many small stopbands with one large one, and this is demonstrated here with example spatial-processing CIC designs that create pencil beams for 1D and 2D receive antenna arrays.

AB We study the problem of allocating limited feedback resources across multiple users in an orthogonal-frequency-division-multiple-access downlink system with slow frequency-domain scheduling. Many flavors of slow frequency-domain scheduling (e. g., persistent scheduling, semi-persistent scheduling), that adapt user-sub-band assignments on a slower time-scale, are being considered in standards such as 3GPP Long-Term Evolution. In this paper, we develop a feedback allocation algorithm that operates in conjunction with any arbitrary slow frequency-domain scheduler with the goal of improving the throughput of the system. Given a user-sub-band assignment chosen by the scheduler, the feedback allocation algorithm involves solving a weighted sum-rate maximization at each (slow) scheduling instant. We first develop an optimal dynamic-programming-based algorithm to solve the feedback allocation problem with pseudo-polynomial complexity in the number of users and in the total feedback bit budget. We then propose two approximation algorithms with complexity further reduced, for scenarios where the problem exhibits additional structure.

AB One of the most popular radiation boundary conditions for the Helmholtz equation in exterior 3-D regions has been the sequence of operators developed by Bayliss et al. 1 for computational domains with spherical exterior boundaries. The present paper extends those spherical operators to triaxial ellipsoidal boundaries by utilizing two mathematical constructs originally developed for ellipsoidal acoustic infinite elements. 2 The two constructs are: (i) a radial/angular coordinate system for ellipsoidal geometry, and (ii) a convergent ellipsoidal radial expansion for exterior fields, analogous to the classical spherical multipole expansion. The ellipsoidal radial and angular coordinates are smooth generalizations of the traditional radial and angular coordinates used in spherical, prolate spheroidal and oblate spheroidal systems. As a result, all four coordinate systems and their corresponding radiation boundary conditions are included within this single ellipsoidal system, varying smoothly from one to the other. The geometric flexibility of this system enables the exterior boundary of the computational domain to closely circumscribe objects with a wide range of aspect ratios, thereby reducing the size and cost of 3-D computational models.

ID OPTIMIZATION
AB Discretization algorithms for semiinfinite minimax problems replace the original problem, containing an infinite number of functions, by an approximation involving a finite number, and then solve the resulting approximate problem. The approximation gives rise to a discretization error, and suboptimal solution of the approximate problem gives rise to an optimization error. Accounting for both discretization and optimization errors, we determine the rate of convergence of discretization algorithms, as a computing budget tends to infinity. We find that the rate of convergence depends on the class of optimization algorithms used to solve the approximate problem as well as the policy for selecting discretization level and number of optimization iterations. We construct optimal policies that achieve the best possible rate of convergence and find that, under certain circumstances, the better rate is obtained by inexpensive gradient methods.

AB TiH2 and TiD2 thick targets were bombarded with 170 keV protons and with 170 keV deuterons. Charged particles from nuclear reactions were observed by means of a surface barrier particle detector shielded by an energy absorbing foil. Deuteron irradiation of TiD2 produced these observations: copious similar to 2.5MeV neutrons and similar to 3MeV protons from direct d-d reactions, gamma rays from p,gamma and n,gamma reactions, similar to 14MeV protons from the secondary d(He-3,p)alpha reaction, and an anomalous, broad energy distribution proton signal between similar to 5-11 MeV. Our observations confirm the anomalous proton emission at a rate similar to 4 x 10(-5) of the d-d fusion rate.

AB The performance of mesoscale meteorological models is evaluated for the coastal zone and Los Angeles area of Southern California, and for the San Joaquin Valley. Several configurations of the Weather Research and Forecasting Model (WRF) with differing grid spacing, initialization, planetary boundary layer (PBL) physics, and land surface models are compared. One configuration of the Coupled Ocean-Atmosphere Mesoscale Prediction System (COAMPS) model is also included, providing results from an independent development and process flow. Specific phenomena of interest for air quality studies are examined. All model configurations are biased toward higher wind speeds than observed. The diurnal cycle of wind direction and speed (land-sea-breeze cycle) as modeled and observed by a wind profiler at Los Angeles International Airport is examined. Each of the models shows different flaws in the cycle. Soundings from San Nicolas Island, a case study involving the Research Vessel (R/V) Atlantis and the NOAA P3 aircraft, and satellite images are used to evaluate simulation performance for cloudy boundary layers. In a case study, the boundary layer structure over the water is poorly simulated by all of the WRF configurations except one with the total energy-mass flux boundary layer scheme and ECMWF reanalysis. The original WRF configuration had a substantial bias toward low PBL heights in the San Joaquin Valley, which are improved in the final configuration. WRF runs with 12-km grids have larger errors in wind speed and direction than those present in the 4-km grid runs.

AB Hurricane Dolly (2008) exhibited dramatic inner-core structural variability during a 6-h rapid intensification and deepening event just prior to making landfall in southern Texas at 1800 UTC 23 July. In particular, the eyewall was highly asymmetric from 0634-1243 UTC, with azimuthal wavenumber m = 4-7 patterns in the eyewall radar reflectivity and prominent mesovortex and polygonal eyewall signatures. Evidence is presented that the most likely cause of the high-wavenumber asymmetries is a convectively modified form of barotropic instability of the thin eyewall potential vorticity ring. The rapid intensification and deepening event occurred while Dolly was in a favorable environment with weak deep-layer vertical wind shear and warm sea surface temperatures; however, the environmental conditions were becoming less favorable during the period of rapid intensification. Therefore, it is plausible that the internal vortex dynamics were dominant contributors to the rapid intensification and deepening.

TI Observations of increasing carbon dioxide concentration in Earth's
thermosphere
SO NATURE GEOSCIENCE
LA English
DT Article
ID ATMOSPHERE; CO2
AB Carbon dioxide occurs naturally throughout Earth's atmosphere. In the thermosphere, CO2 is the primary radiative cooling agent and fundamentally affects the energy balance and temperature of this high-altitude atmospheric layer(1,2). Anthropogenic CO2 increases are expected to propagate upward throughout the entire atmosphere, which should result in a cooler, more contracted thermosphere(3-5). This contraction, in turn, will reduce atmospheric drag on satellites and may have adverse consequences for the orbital debris environment that is already unstable(6,7). However, observed thermospheric mass density trends derived from satellite orbits are generally stronger than model predictions(8,9), indicating that our quantitative understanding of these changes is incomplete. So far, CO2 trends have been measured only up to 35 km altitude(10-12). Here, we present direct evidence that CO2 concentrations in the upper atmosphere-probably the primary driver of long-term thermospheric trends-are increasing. We analyse eight years of CO2 and carbon monoxide mixing ratios derived from satellite-based solar occultation spectra. After correcting for seasonal-latitudinal and solar influences, we obtain an estimated global increase in COx (CO2 and CO, combined) concentrations of 23.5 +/- 6.3 ppm per decade at an altitude of 101 km, about 10 ppm per decade faster than predicted by an upper atmospheric model. We suggest that this discrepancy may explain why the thermospheric density decrease is stronger than expected.

AB Let mu and nu = (nu(1), . . . , nu (k) ) be partitions such that mu is obtained from nu by adding m parts of size r. Descouens and Morita proved algebraically that the modified Macdonald polynomials (H) over tilde (mu) (X; q, t) satisfy the identity (H) over tilde (mu)=(H) over tilde (nu)(H) over tilde ((rm)) when the parameter t is specialize to an mth root of unity. Descouens, Morita, and Numata proved this formula bijectively when r <= nu(k) and r is an element of {1, 2}. This note gives a bijective proof of the formula for all r <= nu(k) .

AB Low serum 25-hydroxyvitamin D [25(OH)D] concentration may increase risk of insulin-requiring diabetes.
A nested case-control study was performed using serum collected during 2002-2008 from military service members. One thousand subjects subsequently developed insulin-requiring diabetes. A healthy control was individually matched to each case on blood-draw date (+/- 2 days), age (+/- 3 months), length of service (+/- 30 days) and sex. The median elapsed time between serum collection and first diagnosis of diabetes was 1 year (range 1 month to 10 years). Statistical analysis used matched pairs and conditional logistic regression.
ORs for insulin-requiring diabetes by quintile of serum 25(OH)D, from lowest to highest, were 3.5 (95% CI 2.0, 6.0), 2.5 (1.5, 4.2), 0.8 (0.4, 1.4), 1.1 (0.6, 2.8) and 1.0 (reference) (p (trend) < 0.001). The quintiles (based on fifths using serum 25(OH)D concentration in the controls) of serum 25(OH)D in nmol/l, were < 43 (median 28), 43-59 (median 52), 60-77 (median 70), 78-99 (median 88) and a parts per thousand yen100 (median 128).
Individuals with lower serum 25(OH)D concentrations had higher risk of insulin-requiring diabetes than those with higher concentrations. A 3.5-fold lower risk was associated with a serum 25(OH)D concentration a parts per thousand yen60 nmol/l.

AB Motivated by new photothermal techniques to detect trace quantities of illicit substances, we are examining the heat transfer of small particles randomly distributed on surfaces that are selectively heated by a laser beam. For an optimal choice of laser power, illumination time and other parameters, we need formulas describing how the thermal signal depends on particle size, their distribution on the substrate surface and thermo-physical properties of the materials involved.
In this manuscript we compare very simple physical models and computational simulations with experimental data from polyethylene microspheres on a polished copper surface, with diameters ranging from 20 to 200 mu m. Heat transfer through air dominates the process, both for single particles and between particles in clusters. The influence of high particle densities per substrate area on the heat transfer process is factored into the simulation by using a cell with just one particle and symmetric boundary conditions. Further simulations where irregular-shaped carbon pieces were approximated as lying cylinders indicate that our simple model can also describe the thermal behavior of a wider class of realistic particles on solid surfaces.

AB Purpose Reduction in anterior cruciate ligament (ACL) injuries in young, active individuals continues to be a major goal in sports medicine. The purpose of this study was to determine the head-neck offset, as measured by AP pelvis alpha angles, in patients presenting to a single surgeon with isolated ACL and non-ACL knee injuries.
Methods In a group of 48 patients with complete, primary ACL rupture and 42 controls with non-ACL injury (i.e., meniscus tear, cartilage defect), a single surgeon, blinded to the diagnosis, took radiographic measures of the AP alpha angle of both hips and the weight-bearing line at both knees. All knee pathology was confirmed with knee arthroscopy. Inclusion criteria included no previous hip or knee surgery, and long-leg standing alignment radiographic series completed at index visit.
Results There was no difference in gender distribution, height, BMI or age between groups. ACL-injured patients had a significantly higher alpha angle (mean = 84, SD = 14) on the injured side than the controls (mean = 59, SD = 7, p < 0.0001). Ninety-four percent of the ACL-injured group had alpha angles over 60 degrees, while only 35% of the non-ACL-injured group had alpha angles over 60 degrees (p = 0.001). Those patients with alpha angle over 60 degrees were 27 times more likely (95% CI 6.4-131) to be in the ACL injury group than those patients with alpha angle 60 degrees or less (p = 0.001).
Conclusion Our findings establish an important preliminary correlation between ACL injury and diminished femoral head-neck offset, as characterized by abnormal, elevated alpha angles.

AB We present a frequency multiplication in Metglas/Pb(Zr,Ti)O-3 (PZT) magnetoelectric (ME) composites which can be tuned by geomagnetic field. Such effect was observed under small dc magnetic biases, and can be operated over a broad frequency range. Moreover, the geomagnetic field can serve as the "ON-OFF" switch for control of the frequency multiplication in ME composites. Thus, a guidance device could be developed to lock onto the direction with largest component of Earth's field. (C) 2012 Elsevier B.V. All rights reserved.

AB Epitaxial graphene (EG) has attracted considerable interest because of its extraordinary properties and ability to be synthesized on the wafer scale. These attributes have enabled EG to be applied in field-effect transistors with extrinsic operating frequencies in the hundreds-of-gigahertz range. Although the quality of EG grown on SiC has improved, there are still obstacles, such as low carrier mobility and large-area thickness nonuniformity, that limit applications in a wide range of truly wafer-scale technologies. In this article, key elements of epitaxial graphene synthesis are highlighted and discussed with regard to impacts on large-area uniformity, structure, and electrical properties. The effects of specific components such as growth-reactor design and substrate quality are examined in an effort to provide a pathway for future advancements in EG production. Finally, key future directions for research in EG are briefly discussed.

AB We present results from the first self-consistent multi-fluid simulations of chromospheric magnetic reconnection in a weakly ionized reacting plasma. We simulate two-dimensional magnetic reconnection in a Harris current sheet with a numerical model which includes ion-neutral scattering collisions, ionization, recombination, optically thin radiative loss, collisional heating, and thermal conduction. In the resulting tearing mode reconnection the neutral and ion fluids become decoupled upstream from the reconnection site, creating an excess of ions in the reconnection region and therefore an ionization imbalance. Ion recombination in the reconnection region, combined with Alfvenic outflows, quickly removes ions from the reconnection site, leading to a fast reconnection rate independent of Lundquist number. In addition to allowing fast reconnection, we find that these non-equilibria partial ionization effects lead to the onset of the nonlinear secondary tearing instability at lower values of the Lundquist number than has been found in fully ionized plasmas. These simulations provide evidence that magnetic reconnection in the chromosphere could be responsible for jet-like transient phenomena such as spicules and chromospheric jets.

AB The 2005 January 21 interplanetary coronal mass ejection (ICME) observed by multiple spacecraft at L1 was also observed from January 21-February 4 at Ulysses (5.3 AU). Previous studies of this ICME have found evidence suggesting that the flanks of a magnetic cloud like structure associated with this ICME were observed at L1 while a more central cut through the associated magnetic cloud was observed at Ulysses. This event allows us to study spatial variation across the ICME and relate it to the eruption at the Sun. In order to examine the spatial dependence of the heating in this ICME, we present an analysis and comparison of the heavy ion composition observed during the passage of the ICME at L1 and at Ulysses. Using SWICS, we compare the heavy ion composition across the two different observation cuts through the ICME and compare it with predictions for heating during the eruption based on models of the time-dependent ionization balance throughout the event.

AB We present observations of ro-vibrational OH and CO emission from the Herbig Be star HD 100546. The emission from both molecules arises from the inner region of the disk extending from approximately 13 AU from the central star. The velocity profiles of the OH lines are narrower than the velocity profile of the [O I] lambda 6300 line, indicating that the OH in the disk is not cospatial with the O I. This suggests that the inner optically thin region of the disk is largely devoid of molecular gas. Unlike the ro-vibrational CO emission lines, the OH lines are highly asymmetric. We show that the average CO and average OH line profiles can be fit with a model of a disk comprised of an eccentric inner wall and a circular outer disk. In this model, the vast majority of the OH flux (75%) originates from the inner wall, while the vast majority of the CO flux (65%) originates on the surface of the disk at radii greater than 13 AU. Eccentric inner disks are predicted by hydrodynamic simulations of circumstellar disks containing an embedded giant planet. We discuss the implications of such a disk geometry in light of models of planet-disk tidal interactions and propose alternative explanations for the origin of the asymmetry.

AB Purpose of review
The treatment for pediatric tracheal stenosis has evolved over the past 50 years. Open airway reconstruction has traditionally been the treatment of choice for this condition. Numerous recent publications now support the use of endoscopic techniques to both augment and sometimes replace open procedures.
Recent findings
During the past 12 months, a significant interest in expanding the role of airway dilation with balloons to manage airway stenoses has emerged. Development of novel airway stents, to include bioabsorbable products, holds promise to decrease the morbidity of stenting procedures. Continued improvement in preoperative imaging, in the form of virtual bronchoscopy, may someday replace airway endoscopy for planning purposes. Additionally, perioperative management strategies and the use of novel adjuvants have been introduced with a goal of improving outcomes in both endoscopic and open techniques through better control of granulation. Ultimately, advances in tissue engineering may provide yet another reconstructive option in the future.
Summary
Endoscopic techniques have an increasing role in the management of pediatric subglottic and tracheal stenosis. However, open airway reconstructive procedures are still required in cases of mature scar, high-grade stenosis, and long-segment stenosis.

TI Proposed Test of Relative Phase as Hidden Variable in Quantum Mechanics
SO FOUNDATIONS OF PHYSICS
LA English
DT Article
DE Quantum measurement; Measurement postulate; Born rule
AB We consider the possibility that the relative phase in quantum mechanics plays a role in determining measurement outcome and could therefore serve as a "hidden" variable. The Born rule for measurement equates the probability for a given outcome with the absolute square of the coefficient of the basis state, which by design removes the relative phase from the formulation. The value of this phase at the moment of measurement naturally averages out in an ensemble, which would prevent any dependence from being observed, and we show that conventional frequency-spectroscopy measurements on discrete quantum systems cannot be imposed at a specific phase due to a straightforward uncertainty relation. We lay out general conditions for imposing measurements at a specific value of the relative phase so that the possibility of its role as a hidden variable can be tested, and we discuss implementation for the specific case of an atomic two-state system with laser-induced fluorescence for measurement.

DE Brillouin scattering; chirped lasers; fiber amplifiers; numerical
simulation
ID SUPPRESSION; AMPLIFIERS; STEADY
AB Numerical simulations are used to solve the coupled partial differential equations describing stimulated Brillouin scattering (SBS) built up from random thermal phonons as a function of time and the longitudinal spatial coordinate in an optical fiber. In the case of a passive fiber, a laser beam is incident with constant power, but its frequency is linearly ramped at 1.55 mu m at a rate of up to 10(16) Hz/s. High chirp rates lead to an increased Brillouin spectral bandwidth and decreased gain. The resulting SBS suppression is well described by an adiabatic model and agrees with experimental results. For an 18-m active fiber pumped at 1.06 mu m and chirped at up to 2 x 10(16) Hz/s, the suppression enables output laser powers in the kilowatt range while maintaining a narrow instantaneous linewidth.

AB The deformation-induced nucleation, growth, distortion, and coalescence of voids have been the subject of numerous experimental, theoretical, and computational studies. However, a vast majority of prior work does not consider the role of the local microstructure on void behavior. The present work considers an isolated cylindrical hole undergoing far-field tensile deformation in cartridge brass (70% Cu, 30% Zn). A polycrystal plasticity model was employed to examine the role of grain-size-to-void-size ratios of 0.14, 1, and 7. These numerical simulations clearly demonstrated that when the grain size is comparable to or larger than the void, inhomogeneous deformation of the microstructure can distort and even overwhelm the role of the void in concentrating plastic strain. To confirm and further elucidate these effects, deformation of brass tensile bars with microscale cylindrical holes was performed in situ in a Scanning Electron Microscope (SEM). This approach permitted Electron Backscattered Diffraction (EBSD) measurements of the evolution of local intra-grain misorientation and full-field Digital Image Correlation (DIC) measurements of the evolution of intragranular strain fields. As expected, when the hole diameter decreased in relation to the grain size, the effects of local microstructure became increasingly important. In an extreme case, the strain localization due to the hole was completely confined within a single grain. In light of these results, existing continuum-based methodologies to represent ductile fracture, such as the Gurson-Tvergaard-Needleman approach and shear-modified variants, may need to be further modified to include these prominent microstructural effects. Such microstructurally-sensitive representations provide one pathway towards stochastic/statistical models for ductile tearing. (c) 2012 Elsevier Ltd. All rights reserved.

AB Rickettsia prowazekii, the etiologic agent of epidemic typhus, is a potential biological threat agent. Its outer membrane protein B (OmpB) is an immunodominant antigen and plays roles as protective envelope and as adhesins. The observation of the correlation between methylation of lysine residues in rickettsial OmpB and bacterial virulence has suggested the importance of an enzymatic system for the methylation of OmpB. However, no rickettsial lysine methyltransferase has been characterized. Bioinformatic analysis of genomic DNA sequences of Rickettsia identified putative lysine methyltransferases. The genes of the potential methyltransferases were synthesized, cloned, and expressed in Escherichia coli, and expressed proteins were purified by nickel-nitrilotriacetic acid (Ni-NTA) affinity chromatography. The methyltransferase activities of the purified proteins were analyzed by methyl incorporation of radioactively labeled S-adenosylmethionine into recombinant fragments of OmpB. Two putative recombinant methyltransferases (rRP789 and rRP027-028) methylated recombinant OmpB fragments. The specific activity of rRP789 is 10- to 30-fold higher than that of rRP027-028. Western blot analysis using specific antibodies against trimethyl lysine showed that both rRP789 and rRP027-028 catalyzed trimethylation of recombinant OmpB fragments. Liquid chromatography-tandem mass spectrometry (LC/MS-MS) analysis showed that rRP789 catalyzed mono-, di-, and trimethylation of lysine, while rRP027-028 catalyzed exclusively trimethylation. To our knowledge, rRP789 and rRP027-028 are the first biochemically characterized lysine methyltransferases of outer membrane proteins from Gram-negative bacteria. The production and characterization of rickettsial lysine methyltransferases provide new tools to investigate the mechanism of methylation of OmpB, effects of methylation on the structure and function of OmpB, and development of methylated OmpB-based diagnostic assays and vaccine candidates.

AB Introduction: Mild traumatic brain injury (MTBI) has emerged as the preeminent injury of combat from the recent conflicts in Iraq and Afghanistan. Very little is known about short-and long-term outcomes after combat-related MTBI. As a measure of outcome after injury, self-rated health is a reliable, widely used measure that assesses perceived health. The primary aim of this study was to determine the effect of combat-related MTBI on self-reported health status after return from deployment. The secondary objective was to examine predictors of a decline in self-reported health status amongst US service members with MTBI, as compared to those service members with other minor non-TBI injuries.
Patients and methods: MTBI cases and an injured comparison group were identified from the Expeditionary Medical Encounter Database records of 1129 male, US service members who experienced blast-related injuries in Iraq from March 2004 to March 2008. Self-rated health was assessed from the routinely administered pre- and post-deployment health assessment questionnaires by the following question, "Overall, how would you rate your health during the past month?" Possible responses were "poor", "fair", "good", "very good", or "excellent." A distinction was made between minor and major negative changes in health (i.e., very good to fair) based on these self-rated health outcomes captured post-injury.
Results: For all personnel, post-injury levels of self-rated health were statistically significantly worse than pre-injury health rating. At 6 months post-injury, service members with MTBI were 5 times more likely to report a major negative change in health as compared to members with other mild injuries. This association was independent of age, rank, branch of service, Injury Severity Score, mental health diagnosis prior to injury, and having been referred to a health care professional.
Discussion: Blast-related injuries, specifically MTBI, during deployment have negative consequences on service members' perception of health. Future research is needed to improve our understanding of the overall effects of MTBI on health and quality of life. (C) 2011 Elsevier Ltd. All rights reserved.

DE Multidisciplinary trauma; Multinational medical staff; Kandahar,

AB Multidisciplinary trauma care systems have been shown to improve patient outcomes. Medical care in support of the global war on terror has provided opportunities to refine these systems.
We report on the multidisciplinary trauma care system at the Role III Hospital at Kandahar Airfield, Afghanistan. We reviewed the Joint Trauma System Registry, Kandahar database from 1 October 2009 to 31 December 2010 and extracted data regarding patient demographics, clinical variables and outcomes. We also queried the operating room records from 1 January 2009 to 31 December 2010.
In the study period of 1 October 2009 to 31 December 2010, 2599 patients presented to the trauma bay, with the most common source of injury being from Improvised Explosive Device (IED) blasts (915), followed by gunshot wounds (GSW) (327). Importantly, 19 patients with triple amputations as a result of injuries from IEDs were seen. 127 patients were massively transfused. The in-hospital mortality was 4.45%.
From 1 January 2010 to 31 December 2010, 4106.24 operating room hours were logged to complete 1914 patient cases. The mean number of procedures per case in 2009 was 1.27, compared to 3.11 in 2010.
Multinational, multidisciplinary care is required for the large number of severely injured patients seen at Kandahar Airfield. Multidisciplinary trauma care in Kandahar is effective and can be readily employed in combat hospitals in Afghanistan and serve as a model for civilian centres. Published by Elsevier Ltd.

AB In this paper, we establish the solvability of martingale solutions for the stochastic Navier-Stokes equations with Ito-Levy noise in bounded and unbounded domains in Rd, d = 2, 3. The tightness criteria for the laws of a sequence of semimartingales is obtained from a theorem of Rebolledo as formulated by Metivier for the Lusin space valued processes. The existence of martingale solutions (in the sense of Stroock and Varadhan) relies on a generalization of Minty-Browder technique to stochastic case obtained from the local monotonicity of the drift term.

TI Biomechanical Analysis of a Transverse Olecranon Fracture Model Using
Tension Band Wiring
SO JOURNAL OF HAND SURGERY-AMERICAN VOLUME
LA English
DT Article
DE Tension band wire; olecranon fracture; biomechanical; osteotomy
olecranon; olecranon fixation
AB Purpose To determine (1) the most distal site at which a tension band construct can maintain bony alignment during dynamic loading of a transverse, length-stable olecranon osteotomy; (2) the location of displacement during cyclical loading; and (3) the ultimate load to failure of the fixation.
Methods We divided 23 non-osteoporotic, fresh-frozen upper extremities into 4 groups. We created transverse osteotomies at 25% of the olecranon surface in group 1, 50% in group II, 75% in group III, and 100% in group IV. We used standard tension band wiring technique to stabilize each osteotomy. We mounted specimens on a biomechanical testing machine at 90 degrees elbow flexion and subjected them to a 150-N sinusoidal load through the triceps tendon at 1 Hz for 500 cycles. An optical motion tracking system synchronized with the testing machine-measured displacement of the osteotomy in any plane. On completion of cycling, we loaded specimens at 1 mm/s until 2-mm displacement occurred. We analyzed data to determine the effect of the location of the osteotomy on load to failure and location of displacement.
Results Of the 23 specimens, 21 survived the cycling process. The 2 specimens that failed were both in group II (50%). Excluding these 2 specimens, the average displacement at the 3 virtual points was less than 1.05 mm in all 4 osteotomy groups. There were no statistical differences between groups. Load to failure was 476, 361, 511, and 610 N for groups I to IV, respectively. Differences between groups were not statistically significant.
Conclusions The stability achieved with tension band wire fixation did not vary with the location of the osteotomy.
Clinical relevance Based on this biomechanical study, when it is properly executed, tension band wire fixation may be used effectively for transverse, length-stable fractures of the olecranon regardless of the amount of articular surface included on the proximal fragment.

DE ballast water; microzooplankton; management; zooplankton; methods
AB In this study, live plankton (epsilon 50 m in minimum dimension) in samples were counted by three analysts to determine counting rates, accuracy and precision of manual microscopy. Counting rates were compared with sample characteristics (e.g. concentration of dead organisms). In separate experiments, plankton proxies, spherical microbeads (49 and 150 m in diameters), were added to samples with varying degrees of debris loading, including samples from full-scale, replica ballast tanks. These analyses were used to test the hypothesis that as debris loading increases, counting rate increases and accuracy decreases. Highly concentrated samples and samples with high concentrations of dead plankton resulted in significantly slower counting rates. The recovery of 50-m microbeads was lowest (75) in laboratory samples that contained the highest debris load. The recovery of 150-m microbeads was very high (98) in laboratory samples with and without debris. Field samples from the replica ballast tank were highly turbid, and microbead recoveries were low for both microbead sizes. Sample quality, therefore, will affect counting rates and accuracy and will limit the volume of the sample that can be analyzed within short-time windows available for counting live plankton samples.

AB Background: Renal cell carcinoma is the seventh leading cause of cancer deaths. Studies have shown patients with solitary osseous metastases have a better prognosis; however, methods of resection are not well defined. The purpose of this study was to review factors associated with survival and assess the impact of wide versus intralesional management on function and disease-specific outcomes in patients with renal cell carcinoma metastases.
Methods: Sixty-nine patients with 86 osseous renal cell metastases were reviewed. Potential factors associated with survival were evaluated with KaplanMeier curves. ANOVA was performed to compare means between groups.
Results: One year survival for the group was 77% and 32.5% at 5 years. The absence of metastatic disease at presentation, nephrectomy, and pre-operative status were associated with improved survival. There was a lower rate of local recurrence with wide resection (5%) versus intralesional procedures (27%).
Conclusions: Improved pre-operative status, nephrectomy, and metachronous lesions had better overall survival. Wide resection results in decreased local recurrence and revision surgeries. However, it did not reliably predict improved survival. Our recommendation is for individual evaluation of each patient with osseous renal cell carcinoma metastases. Wide excision may be used for resectable lesions to prevent local progression and subsequent surgeries. J. Surg. Oncol. 2012; 106:850855. (C) 2012 Wiley Periodicals, Inc.

AB The purpose of this research is twofold. First, we present a new generalized form of the discrete Smoluchowski agglomeration equations derived from a weak formulation of the continuous equations which provides a direct extension of the equations to poly-sized particles. This formulation is shown to preserve particle mass conservation provided the test functions form a partition of unity, and yields a class of algorithms having straightforward and efficient implementations. Verifications and computed convergence rates of the numerical algorithm, comparisons to other methods, and validations of agglomeration due to turbulent shear are provided. Secondly, we use these algorithms for a study of two-species (agent-countermeasure) particle agglomeration. Computations based on the solution of the non-dimensional equations are provided and applied to an analysis of agent reduction through the introduction of counter-measure particles for both turbulent shear and acoustic agglomeration.

DE system-of-systems (SoS) acquisition; contracting structures; contracting
processes; organizational structures
AB Acquisition of a system-of-systems can be an all new acquisition of multiple systems that are intended to operate together as a system-of-systems. Much more common in the U.S. Department of Defense (DoD) is acquisition of one or more new systems that are intended to interoperate with existing systems as a system of systems (SoS) with new capabilities. In either case, successful SoS acquisition necessarily depends on effective contracting structures and processes for SoS acquisition. In this paper, a set of issues that need to be addressed in SoS acquisition are identified, and the current findings discussed. The findings suggest maintaining an extensive systems engineering effort within the SoS acquisition and changes to the existing contracting processes, structures, and organizational structures to maximize the probability of SoS acquisition success. The resulting changes are recommended to current and future DoD SoS acquisitions. (C) 2012 Wiley Periodicals, Inc. Syst Eng 15

DE Random vibration; Accelerated life; Fatigue; Frequency shift; Life
estimation
AB Life estimation of structures subjected to non-uniform random vibration analysis has historically been done through the use of fatigue properties. In general, evaluation of the severity of the vibration environment is performed at the initial natural frequency. It is widely known, however, that many structures will undergo a frequency change during failure. If the random vibration is non-uniform with large peaks and valleys, the frequency change will result in a changing stress state that must be accounted for. Evaluation of the accumulated damage can be done through accounting for the natural frequency change. This model uses experimental data to determine two empirical constants to predict time to failure for various complex random vibration profiles. Although the new model will utilize an experimental component in lieu of FEA, the physics of the underlying failure will be retained. Additionally the model has shown good correlation to experimental data, and improvements over existing techniques. Published by Elsevier Ltd.

ID CLASSIFICATION; SECURITY
AB Unintentional modulations of the electromagnetic signal of radio-frequency (RF) emitters are used to identify individual sources of signals as unique from emitters of the same type in a procedure known as RF fingerprinting. It allows for the identification and tracking of physical threats, prevention of unauthorized access, and detecting cloning of sensitive devices. Machine learning techniques assist RF fingerprinting by providing automatic recognition of these unique aspects of individual RF emitters. RF identification (RFID) tags are a common RF emitter used to track supplies and are also present in credit cards and passports to allow for automatic recognition or monetary transfers. Despite advances in RFID cryptography, RFID tags can still be easily cloned and tracked. Here, we implement RF fingerprinting to authenticate individual RFID tags at the physical layer. Features are extracted using the dynamic wavelet fingerprint, and supervised pattern classification techniques are used to identify unique RFID tags with up to 99% accuracy.

AB The potential for encapsulating RNA within tunable, semi-permeable structures for storage and transportation purposes offers an interesting approach to the reduction of stringent storage requirements that often hamper the field application of genetic analysis methods. In this study, we assessed the potential for application of functionalized, porous silicate sorbents in maintaining nucleic acid integrity. Mesoporous silica nanoparticles (MSNs) with and without incorporated stabilizing reagents were used to encapsulate triosephosphate isomerase mRNA of Arabidopsis thaliana. The absorption, elution, and the long-term stability of the RNA were monitored by using quantitative real-time RT-PCR. The results indicate that adsorbed RNA can be eluted from the sorbents using simple buffers and employed directly for downstream molecular diagnostic assays without any further processing. RNA integrity can be maintained for extended time periods under refrigeration temperatures in the presence of covalently immobilized stabilizing compounds. This study provides initial evidence of the potential for application of MSNs in transportation and storage. They may also have utility in sample collection and processing in restrictive environments.

AB We present a study of various aspects of proximity effects in F/S (ferromagnet/superconductor) bilayers, where F has a spiral magnetic texture such as that found in holmium, erbium, and other materials, and S is a conventional s-wave superconductor. We numerically solve the Bogoliubov-de Gennes (BdG) equations self-consistently and use the solutions to compute physical quantities relevant to the proximity effects in these bilayers. We obtain the relation between the superconducting transition temperature T-c and the thicknesses d(F) of the magnetic layer by solving the linearized BdG equations. We find that the T-c (d(F)) curves include multiple oscillations. Moreover, the system may be reentrant not only with d(F), as is the case when the magnet is uniform, but also with temperature T : the superconductivity disappears in certain ranges of d(F) or T. The T reentrance reported here occurs when d(F) is larger than the spatial period of the conical exchange field. We compute the condensation free energies and entropies from the full BdG equations and find the results are in agreement with T-c values obtained by linearization. The inhomogeneous nature of the magnet makes it possible for all odd triplet pairing components to be induced. We have investigated their properties and found that, as compared to the singlet amplitude, both the m = 0 and +/- 1 triplet components exhibit long-range penetration. For nanoscale bilayers, the proximity lengths for both layers are also obtained. These lengths oscillate with d(F) and they are found to be long range on both sides. These results are shown to be consistent with recent experiments. We also calculate the reverse proximity effect described by the three-dimensional local magnetization, and the local density of states, which reveals important energy-resolved signatures associated with the proximity effects.

AB The light emitted by stars and accreting compact objects through the history of the universe is encoded in the intensity of the extragalactic background light (EBL). Knowledge of the EBL is important to understand the nature of star formation and galaxy evolution, but direct measurements of the EBL are limited by galactic and other foreground emissions. Here, we report an absorption feature seen in the combined spectra of a sample of gamma-ray blazars out to a redshift of z similar to 1.6. This feature is caused by attenuation of gamma rays by the EBL at optical to ultraviolet frequencies and allowed us to measure the EBL flux density in this frequency band.

AB The lattice thermal conductivity (kappa) of the thermoelectric materials, Mg2Si, Mg2Sn, and their alloys, are calculated for bulk and nanowires, without adjustable parameters. We find good agreement with bulk experimental results. For large nanowire diameters, size effects are stronger for the alloy than for the pure compounds. For example, in 200 nm diameter nanowires kappa is lower than its bulk value by 30%, 20%, and 20% for Mg2Si0.6Sn0.4, Mg2Si, and Mg2Sn, respectively. For nanowires less than 20 nm thick, the relative decrease surpasses 50%, and it becomes larger in the pure compounds than in the alloy. At room temperature, kappa of Mg2SixSn1-x is less sensitive to nanostructuring size effects than SixGe1-x, but more sensitive than PbTexSe1-x. This suggests that further improvement of Mg2SixSn1-x as a nontoxic thermoelectric may be possible.

AB A parameter that is often used to characterize the dynamics of supercooled liquids is the dynamic fragility, however it is still debated how the fragility is related to other physical properties. Recent experimental data on colloidal systems have found that fragility decreases with increasing softness of the intermolecular potential. This result is in apparent disagreement with recent molecular dynamics simulations reporting the opposite behavior. Herein, using the thermodynamical scaling exponent gamma as a measure of the steepness of the potential we show how these different results can be reconciled and also agree with previous results obtained for the dynamics of supercooled liquids at high pressures.

AB From the Surface Velocity Program (SVP) drifter current and QuikSCAT wind data, the relationship between the observed near-surface current vectors and surface wind vectors for the northwestern Pacific Ocean under high winds (20-50 m s(-1)) are obtained with quantitative estimations of near-surface drift ratio (current speed versus wind speed) r (similar to 2%) and near-surface drift angle alpha (similar to 0 degrees-10 degrees to the right of the winds). These estimations keep unchanged after removing the surface geostrophic component. From the SVP drifter current and daily WindSat wind data, the estimated r is still approximately 2%. Three linear regression equations are obtained between the observed near-surface current speeds and the surface wind stress for the high wind range.

AB We probe the degree of circular polarization of the emitted photoluminescence from a single MoS2 as a function of the circularly polarized photo-excitation energy. A Single layer of MoS2 has strong emission at around 1.9 eV associated with a direct transition at the K-point of the Brillouin zone. The circular polarization of the photoluminescence is very high for excitation near the bandgap and has a power-law decrease as the excitation energy increases. We identify phonon-assisted intervalley scattering as the primary spin relaxation mechanism and present a model that explains the wide variation in values for the polarization reported in the literature.

AB Combustion analysis of three different thermites consisting of aluminum (Al) particles with and without surface functionalization combined with molybdenum trioxide (MoO3) was performed to study the effect of surface functionalization on flame propagation velocity (FPV). Two types of Al particles had self-assembled monolayers (SAMs) of perfluoro tetradecanoic (PFTD) and perfluoro sebacic (PFS) acids around the alumina shell, respectively; the other one did not. Flame speeds for Al with PFTD acid combined with MoO3 are 86% higher than Al/MoO3 whereas those for Al with PFS acid combined with MoO3 are almost half of Al/MoO3. The Al-PFTD structure is more sterically hindered and exhibits lower bond dissociation energy. This chemistry promotes increased flame speeds. Thermal equilibrium studies were performed using a differential scanning calorimeter and a thermogravimetric analyzer to determine activation energy (E-a) of the thermites. Results are consistent with flame speed observations and showed an inverse relationship between flame speed and E-a. This study shows that Surface functionalization can be used as an approach to control the reactivity of Al particles.

AB A new inversion algorithm based on the maximum entropy method (MEM) is proposed to remove unwanted effects in fast neutron imaging which result from an uncollimated source interacting with a finitely thick scintillator. The algorithm takes as an input the image from the thick scintillator (TS) and the radiography setup geometry. The algorithm then outputs a restored image which appears as if taken with an infinitesimally thin scintillator (ITS). The inversion is accomplished by numerically generating a probabilistic model relating the ITS image to the TS image and then inverting this model on the TS image through MEM. Algorithm details as well as numerical results using MCNP simulated images are presented. This reconstruction technique can reduce the exposure time or the required source intensity without undesirable object blurring on the image by allowing the use of both thicker scintillators with higher efficiencies and closer source-to-detector distances to maximize incident radiation flux. The technique should also be applicable to high energy gamma or x-ray radiography using thick scintillators. (C) 2012 Elsevier B.V. All rights reserved.

AB Recent numerical experiments of Pecora et al. [Phys. Rev. E 83, 065201 (2011)] have investigated tunneling between two-dimensional symmetric double wells separated by a tunneling barrier. The wells were bounded by hard walls and by the potential barrier which was created by a step increase from the zero potential within a well to a uniform barrier potential within the barrier region, which is a situation potentially realizable in the context of quantum dots. Numerical results for the splitting of energy levels between symmetric and antisymmetric eigenstates were calculated. It was found that the splittings vary erratically from state to state, and the statistics of these variations were studied for different well shapes with the fluctuation levels being much less in chaotic wells than in comparable nonchaotic wells. Here we develop a quantitative theory for the statistics of the energy level splittings for chaotic wells. Our theory is based on the random plane wave hypothesis of Berry. While the fluctuation statistics are very different for chaotic and nonchaotic well dynamics, we show that the mean splittings of differently shaped wells, including integrable and chaotic wells, are the same if their well areas and barrier parameters are the same. We also consider the case of tunneling from a single well into a region with outgoing quantum waves.

AB Photolytic transformation of the propellants 2,4-dinitrotoluene (2,4-DNT) and 2,6-dinitrotoluene (2,6-DNT) produces 2,4-dinitrobenzyl alcohol (2,4-DNBOH), 2,6-dinitrobenzyl alcohol (2,6-DNBOH), 2,4-dinitrobenzaldehyde (2,4-DNBCHO), 2,6-dinitrobenzaldehyde (2,6-DNCHO), 2,4-dinitrobenzoic acid (2,4-DNBCOOH) and 2-amino 4-nitrobenzoic acid (2A4NBA). In this work, the photolysis rates of the products of the parent dinitrotoluenes in both natural and laboratory-prepared waters were measured. The photochemical degradation was studied using a Suntest CPS+(R) solar simulator equipped with various filters designed to select specific regions of the solar spectrum. HPLC analysis was used to determine the degradation rates of the compounds. Photolysis rates of the alcohols and aldehydes were influenced by the wavelength of the light irradiating the compound; 295, 305, and 320 nm long-pass filter exposures produced similar rates of degradation while the 395 nm filter exposure produced minimal degradation. Under the 295-nm filter, the first-order degradation rate constants were highest for 2,6-DNBOH (4 h(-1)), followed by 2,4-DNBCHO and 2,6-DNBCHO (3 h(-1)), with the smallest for 2,4-DNBOH (2 h(-1)). The aqueous phase composition (filtered seawater, estuary water, ultrapure water) had minimal impact on the photolysis rates. All four compounds were degraded faster than the parent 2,4-DINFT and 2,6-DNT. In contrast, the 2,4-DNBCOOH and 2A4NBA were not photolyzed under any of the conditions studied.

AB Semiconductor quantum dots (QDs) are attractive probes for optical sensing and imaging due to their unique photophysical attributes and nanoscale size. In particular, the development of assays and biosensors based on QDs and Forster resonance energy transfer (FRET) continues to be a prominent focus of research. Here, we demonstrate the application of QDs as simultaneous donors and acceptors in a time-gated FRET relay for the multiplexed detection of protease activity. In contrast to the current state-of-the-art, which uses multiple colors of QDs, multiplexing was achieved using only a single color of QD. The other constituents of the FRET relay, a luminescent terbium complex and fluorescent dye, were assembled to QDs via peptides that were selected as substrates for the model proteases trypsin and chymotrypsin. Loss of prompt FRET between the QD and dye signaled the activity of chymotrypsin; loss of time-gated FRET between the terbium and QD signaled the activity of trypsin. We applied the FRET relay in a series of quantitative, real-time kinetic assays of increasing biochemical complexity, including multiplexed sensing, measuring inhibition in a multiplexed format, and tracking the proteolytic activation of an inactive pro-protease to its active form in a coupled, multienzyrne system. These capabilities were derived from a ratiometric analysis of the two FRET pathways in the relay and permitted extraction of initial reaction rates, enzyme specificity constants, and apparent inhibition constants. This work adds to the growing body of research on multifunctional nanoparticles and introduces multiplexed sensing as a novel capability for a single nanoparticle vector. Furthermore, the ability to track both enzymes within a coupled biological system using one vector represents a significant advancement for nanoparticle-based biosensing. Prospective applications in biochemical research, applied diagnostics, and drug discovery are discussed.

ID OCEAN
AB In this paper, an optimal out-of-band (OOB) correction transform (OOBCT) for dealing with onboard Visible/Infrared Imaging Radiometer Suite (VIIRS) OOB effects is proposed. This paper addresses the OOB response issue without consideration of the impact of other error sources on the correction processing. The OOBCT matrix is derived by minimizing an objective function of error summation between the expected and realistic recovered band-averaged spectral radiances. Using the VIIRS filter transmittance functions for all multiband sensors obtained from prelaunch laboratory measurements and a simulated dataset obtained from Airborne Visible InfraRed Imaging Spectrometer (AVIRIS) hyperspectral data, the OOBCT matrix is numerically computed. The processing of the OOB correction is straightforward and can be performed by a product between the OOBCT matrix and a measured multispectral image vector. The experimental results with both AVIRIS and Hyperspectral Imager for the Coastal Ocean datasets demonstrate that the ratios of average errors of recovered band-averaged spectral radiances divided by the measured radiances with the OOB responses are less than 4%. The average values of the relative errors for all pixels and bands indicate that the OOBCT method outperforms the works reported in literature. (C) 2012 Optical Society of America

AB We have investigated the onset and acceleration of coronal mass ejections (CMEs) and eruptive flares. To isolate the eruption physics, our study uses the breakout model, which is insensitive to the energy buildup process leading to the eruption. We performed 2.5D simulations with adaptive mesh refinement that achieved the highest overall spatial resolution to date in a CME/eruptive flare simulation. The ultra-high resolution allows us to separate clearly the timing of the various phases of the eruption. Using new computational tools, we have determined the number and evolution of all X- and O-type nulls in the system, thereby tracking both the progress and the products of reconnection throughout the computational domain. Our results show definitively that CME onset is due to the start of fast reconnection at the breakout current sheet. Once this reconnection begins, eruption is inevitable; if this is the only reconnection in the system, however, the eruption will be slow. The explosive CME acceleration is triggered by fast reconnection at the flare current sheet. Our results indicate that the explosive eruption is caused by a resistive instability, not an ideal process. Moreover, both breakout and flare reconnections begin first as a form of weak tearing characterized by slowly evolving plasmoids, but eventually transition to a fast form with well-defined Alfvenic reconnection jets and rapid flux transfer. This transition to fast reconnection is required for both CME onset and explosive acceleration. We discuss the key implications of our results for CME/flare observations and for theories of magnetic reconnection.

AB We present findings for DoAr 24E, a binary system that includes a classical infrared companion. We observed the DoAr 24E system with the Spitzer Infrared Spectrograph (IRS), with high-resolution, near-infrared spectroscopy of CO vibrational transitions, and with mid-infrared imaging. The source of high extinction toward infrared companions has been an item of continuing interest. Here we investigate the disk structure of DoAr 24E using the column densities, temperature, and velocity profiles of two CO absorption features seen toward DoAr 24Eb. We model the spectral energy distributions found using T-ReCS imaging and investigate the likely sources of extinction toward DoAr 24Eb. We find the lack of silicate absorption and small CO column density toward DoAr 24Eb suggest that the mid-infrared continuum is not as extinguished as the near-infrared, possibly due to the mid-infrared originating from an extended region. This, along with the velocity profile of the CO absorption, suggests that the source of high extinction is likely due to a disk or disk wind associated with DoAr 24Eb.

TI CHARACTERIZING THE OPTICAL VARIABILITY OF BRIGHT BLAZARS:

AB We investigate the use of optical photometric variability to select and identify blazars in large-scale time-domain surveys, in part to aid in the identification of blazar counterparts to the similar to 30% of gamma-ray sources in the Fermi 2FGL catalog still lacking reliable associations. Using data from the optical LINEAR asteroid survey, we characterize the optical variability of blazars by fitting a damped random walk model to individual light curves with two main model parameters, the characteristic timescales of variability tau, and driving amplitudes on short timescales (sigma) over cap Imposing cuts on minimum tau and (sigma) over cap allows for blazar selection with high efficiency E and completeness C. To test the efficacy of this approach, we apply this method to optically variable LINEAR objects that fall within the several-arcminute error ellipses of gamma-ray sources in the Fermi 2FGL catalog. Despite the extreme stellar contamination at the shallow depth of the LINEAR survey, we are able to recover previously associated optical counterparts to Fermi active galactic nuclei with E >= 88% and C = 88% in Fermi 95% confidence error ellipses having semimajor axis r < 8'. We find that the suggested radio counterpart to Fermi source 2FGL J1649.6+5238 has optical variability consistent with other gamma-ray blazars and is likely to be the gamma-ray source. Our results suggest that the variability of the non-thermal jet emission in blazars is stochastic in nature, with unique variability properties due to the effects of relativistic beaming. After correcting for beaming, we estimate that the characteristic timescale of blazar variability is similar to 3 years in the rest frame of the jet, in contrast with the similar to 320 day disk flux timescale observed in quasars. The variability-based selection method presented will be useful for blazar identification in time-domain optical surveys and is also a probe of jet physics.

AB High-resolution spectra from the Hinode EUV Imaging Spectrometer have revealed that coronal spectral line profiles are sometimes asymmetric, with a faint enhancement in the blue wing on the order of 100 km s(-1). These asymmetries could be important since they may be subtle yet diagnostically useful signatures of coronal heating or solar wind acceleration processes. It has also been suggested that they are signatures of chromospheric jets supplying mass and energy to the corona. Until now, however, there have been no studies of the physical properties of the plasma producing the asymmetries. Here we identify regions of asymmetric profiles in the outflows of AR 10978 using an asymmetric Gaussian function and extract the intensities of the faint component using multiple Gaussian fits. We then derive the temperature structure and chemical composition of the plasma producing the asymmetries. We find that the asymmetries are dependent on temperature, and are clearer and stronger in coronal lines. The temperature distribution peaks around 1.4-1.8 MK with an emission measure at least an order of magnitude larger than that at 0.6 MK. The first ionization potential bias is found to be 3-5, implying that the high-speed component of the outflows may also contribute to the slow-speed wind. Observations and models indicate that it takes time for plasma to evolve to a coronal composition, suggesting that the material is trapped on closed loops before escaping, perhaps by interchange reconnection. The results, therefore, identify the plasma producing the asymmetries as having a coronal origin.

AB A synthetic polymeric lens was designed and fabricated based on a bio-inspired, "Age=5" human eye lens design by utilizing a nanolayered polymer film-based technique. The internal refractive index distribution of an anterior and posterior GRIN lens were characterized and confirmed against design by mu ATR-FTIR. 3D surface topography of the fabricated aspheric anterior and posterior lenses was measured by placido-cone topography and exhibited confirmation of the desired aspheric surface shape. Furthermore, the wavefronts of aspheric posterior GRIN and PMMA lenses were measured and simulated by interferometry and Zemax software, respectively. Their results show that the gradient index distribution reduces the overall wavefront error as compared a homogenous PMMA lens of an identical geometry. Finally, the anterior and posterior GRIN lenses were assembled into a bio-inspired GRIN human eye lens through which a clear imaging was possible. (C)2012 Optical Society of America

AB We have theoretically and experimentally investigated using a dual parallel Mach-Zehnder modulator (DP-MZM) in an RF photonic link to cancel the second harmonic distortion due to the photodiode. Biasing the DP-MZM for single sideband modulation, the second harmonic generated by the DP-MZM can be set out of phase with the second harmonic generated at the photodiode. We measure the output intercept point of the second harmonic distortion of the link to be 55.3 dBm, which is an improvement of over 32 dB as compared to only the photodiode.

AB Lung disease is common among wild and managed populations of bottlenose dolphins Tursiops truncatus. The purpose of the study was to apply standardized techniques to the ultrasound evaluation of dolphin lungs, and to identify normal and abnormal sonographic findings associated with pleuropulmonary diseases. During a 5 yr period (2005 to 2010), 498 non-cardiac thoracic ultrasound exams were performed on bottlenose dolphins at the Navy Marine Mammal Program in San Diego, California, USA. Exams were conducted as part of routine physical exams, diagnostic workups, and disease monitoring. In the majority of routine exams, no abnormal pleural or pulmonary findings were detected with ultrasound. Abnormal findings were typically detected during non-routine exams to identify and track disease progression or resolution; therefore, abnormal results are overrepresented in the study. In order of decreasing prevalence, abnormal sonographic findings included evidence of alveolar-interstitial syndrome, pleural effusion, pulmonary masses, and pulmonary consolidation. Of these findings, alveolar-interstitial syndrome was generally nonspecific as it represented several possible disease states. Pairing ultrasound findings with clinical signs was critical to determine relevance. Pleural effusion, pulmonary masses, and pulmonary consolidation were relatively straightforward to diagnose and interpret. Further diagnostics were performed to obtain definitive diagnoses when appropriate, specifically ultrasound-guided thoracocentesis, fine needle aspirates, and lung biopsies, as well as radiographs and computed tomography (CT) exams. Occasionally, post mortem gross necropsy and histopathology data were available to provide confirmation of diagnoses. Thoracic ultrasound was determined to be a valuable diagnostic tool for detecting pleural and pulmonary diseases in dolphins.

AB Background: Limited research has examined the association between physical activity, health-related fitness, and disease outcomes in breast cancer survivors. Here, we present the rationale and design of the Alberta Moving Beyond Breast Cancer (AMBER) Study, a prospective cohort study designed specifically to examine the role of physical activity and health-related fitness in breast cancer survivorship from the time of diagnosis and for the balance of life. The AMBER Study will examine the role of physical activity and health-related fitness in facilitating treatment completion, alleviating treatment side effects, hastening recovery after treatments, improving long term quality of life, and reducing the risks of disease recurrence, other chronic diseases, and premature death.
Methods/Design: The AMBER Study will enroll 1500 newly diagnosed, incident, stage I-IIIc breast cancer survivors in Alberta, Canada over a 5 year period. Assessments will be made at baseline (within 90 days of surgery), 1 year, and 3 years consisting of objective and self-reported measurements of physical activity, health-related fitness, blood collection, lymphedema, patient-reported outcomes, and determinants of physical activity. A final assessment at 5 years will measure patient-reported data only. The cohort members will be followed for an additional 5 years for disease outcomes.
Discussion: The AMBER cohort will answer key questions related to physical activity and health-related fitness in breast cancer survivors including: (1) the independent and interactive associations of physical activity and health-related fitness with disease outcomes (e.g., recurrence, breast cancer-specific mortality, overall survival), treatment completion rates, symptoms and side effects (e.g., pain, lymphedema, fatigue, neuropathy), quality of life, and psychosocial functioning (e.g., anxiety, depression, self-esteem, happiness), (2) the determinants of physical activity and health-related fitness including demographic, medical, social cognitive, and environmental variables, (3) the mediators of any observed associations between physical activity, health-related fitness, and health outcomes including biological, functional, and psychosocial, and (4) the moderators of any observed associations including demographic, medical, and biological/disease factors. Taken together, these data will provide a comprehensive inquiry into the outcomes, determinants, mechanisms, and moderators of physical activity and health-related fitness in breast cancer survivors.

AB Currently, a consensus exists that low intensity non-impact blast wave exposure leads to mild traumatic brain injury (mTBI). Considerable interest in this "invisible injury" has developed in the past few years but a disconnect remains between the biomedical outcomes and possible physical mechanisms causing mTBI. Here, we show that a shock wave travelling through the brain excites a phonon continuum that decays into specific acoustic waves with intensity exceeding brain tissue strength. Damage may occur within the period of the phonon wave, measured in tens to hundreds of nanometers, which makes the damage difficult to detect using conventional modalities.

SO JOURNAL OF APPLIED PHYSICS

AB Terahertz time-domain spectroscopy has found widespread application due to a number of attractive features including phase-sensitive detection and subpicosecond temporal resolution. Recently, the application of this technique to study ensembles of sub-wavelength ferromagnetic particles resulted in the observation of novel and unusual effects. The shape, relative transmission amplitude, and time delay of a broadband terahertz waveform were sensitive to the magnitude and direction of an applied magnetic field and to the magnetization states of the particles. Furthermore, the addition of a thin coating of nonmagnetic metal (Au) at the surface of the particles had a profound effect on these characteristics. To better understand the new phenomena, a terahertz time-domain spectroscopy investigation of ensembles of ferromagnetic particles is presented in which the test range of magnetic field is extended, including significantly larger magnitude as well as both field polarities. By sweeping the applied field continuously through zero, hysteretic effects are now observed. Furthermore, we show that the effects of a thin nonmagnetic metal coating are not unique to Au. These effects are also observed in particle ensembles in which the ferromagnetic particles are coated with thin Al or Ag films. (C) 2012 American Institute of Physics.

AB A systematic study is presented for centrality, transverse momentum (p(T)), and pseudorapidity (eta) dependence of the inclusive charged hadron elliptic flow (v(2)) at midrapidity (vertical bar eta vertical bar < 1.0) in Au + Au collisions at root s(NN) = 7.7, 11.5, 19.6, 27, and 39 GeV. The results obtained with different methods, including correlations with the event plane reconstructed in a region separated by a large pseudorapidity gap and four-particle cumulants (v(2){4}), are presented to investigate nonflow correlations and v(2) fluctuations. We observe that the difference between v(2){2} and v(2){4} is smaller at the lower collision energies. Values of v(2), scaled by the initial coordinate space eccentricity, v(2)/epsilon, as a function of p(T) are larger in more central collisions, suggesting stronger collective flow develops in more central collisions, similar to the results at higher collision energies. These results are compared to measurements at higher energies at the Relativistic Heavy Ion Collider (root s(NN) = 62.4 and 200 GeV) and at the Large Hadron Collider (Pb + Pb collisions at root s(NN) = 2.76 TeV). The v(2)(pT) values for fixed pT rise with increasing collision energy within the pT range studied (<2 GeV/c). A comparison to viscous hydrodynamic simulations is made to potentially help understand the energy dependence of v(2)(pT). We also compare the v(2) results to UrQMD and AMPT transport model calculations, and physics implications on the dominance of partonic versus hadronic phases in the system created at beam energy scan energies are discussed.

AB Excited levels of Te-128 to 3.3 in MeV excitation have been studied using gamma-ray spectroscopy following inelastic scattering of accelerator-produced neutrons. Spectroscopic information, including transition energies, level spins, E2/M1 multipole-mixing ratios, and gamma-ray branching ratios, was determined from gamma-ray excitation functions measured from E-n = 2.15-3.33 MeV in 90-keV increments, gamma-ray angular distributions measured at E-n = 2.2, 2.8, and 3.3 MeV, and gamma gamma coincidences measured at E-n = 3.6 MeV. Lifetimes of levels in Te-128 were deduced using Doppler-shift attenuation techniques. Absolute transition probabilities were determined for many levels and compared to interacting boson model and particle-core coupling model calculations to identify few particle and collective structures; states exhibiting the decay characteristics expected for two-phonon, mixed-symmetry, and quadrupole-octupole coupled states are identified.

To understand the toxicology of these alloys, male F344 rats were intramuscularly implanted with pellets of tungsten/nickel/cobalt, tungsten/nickel/iron, or pure tungsten, with tantalum pellets as a negative control. Between 6 and 12 months, aggressive rhabdomyosarcomas formed around tungsten/nickel/cobalt pellets, while those of tungsten/nickel/iron or pure tungsten did not cause cancers. Electron microscopy showed a progressive corrosion of the matrix phase of tungsten/nickel/cobalt pellets over 6 months, accompanied by high urinary concentrations of nickel and cobalt. In contrast, non-carcinogenic tungsten/nickel/iron pellets were minimally corroded and urinary metals were low; these pellets having developed a surface oxide layer in vivo that may have restricted the mobilization of carcinogenic nickel. Microarray analysis of tumors revealed large changes in gene expression compared with normal muscle, with biological processes involving the cell cycle significantly up-regulated and those involved with muscle development and differentiation significantly down-regulated. Top KEGG pathways disrupted were adherens junction, p53 signaling, and the cell cycle. Chromosomal enrichment analysis of genes showed a highly significant impact at cytoband 7q22 (chromosome 7) which included mouse double minute (MDM2) and cyclin-dependant kinase (CDK4) as well as other genes associated with human sarcomas. In conclusion, the tumorigenic potential of implanted tungsten alloys is related to mobilization of carcinogenic metals nickel and cobalt from corroding pellets, while gene expression changes in the consequent tumors are similar to radiation induced animal sarcomas as well as sporadic human sarcomas.

AB Many sea surface temperature (SST) gap-free gridded analysis (Level 4, or L4) fields are produced by various groups in different countries. The Group for High Resolution SST (GHRSST) is an international collaboration body which has formed the inter-comparison technical advisory group (IC-TAG), to advise SST producers and users on the relative performance of these SST fields. This two-part paper describes two of the three major systems developed under GHRSST coordination towards this goal. Part one (this paper) describes the GHRSST Multi-Product Ensemble (GMPE) system, which runs on a daily basis at the UK Met Office, taking various L4 analyses as inputs, transferring them onto a common grid, and producing an ensemble median and standard deviation. The various analysis systems contributing to the GHRSST inter-comparisons are discussed, highlighting areas of commonality between the systems as well as those parts of the systems where there is less agreement on the appropriate algorithmic or parametric choices. The characteristics of the contributing L4 analyses are demonstrated by comparing them to near-surface Argo profile temperature data, which provide an independent measurement of SST and have been shown to provide a good estimate of foundation SST (the SST free of diurnal warming). The feature resolution characteristics of the L4 analyses are demonstrated by calculating horizontal gradients of the SST fields (on their original grid). The accuracy and resolution of the GMPE median are compared with those of the input analyses using the same metrics, showing that the GMPE median is more accurate than any of the contributing analyses with a standard deviation error of 0.40 K globally with respect to near-surface Argo data. For use in climate applications such as trend analysis or assimilation into climate models, it is important to have a good measure of uncertainty, so the suitability of the GMPE standard deviation as a measure of uncertainty is explored. This assessment shows that, over large spatial and temporal scales, the spread in the ensemble does have a strong relationship with the error in the median, although it underestimates the error by about one third.

AB There are a growing number of level 4 (L4; gap-free gridded) sea surface temperature (SST) products generated by blending SST data from various sources which are available for use in a wide variety of operational and scientific applications. In most cases, each product has been developed for a specific user community with specific requirements guiding the design of the product. Consequently differences between products are implicit. In addition, anomalous atmospheric conditions, satellite operations and production anomalies may occur which can introduce additional differences. This paper describes a new web-based system called the L4 SST Quality Monitor (L4-SQUAM) developed to monitor the quality of L4 SST products.
L4-SQUAM intercompares thirteen L4 products with 1-day latency in an operational environment serving the needs of both L4 SST product users and producers. Relative differences between products are computed and visualized using maps, histograms, time series plots and Hovmoller diagrams, for all combinations of products. In addition, products are compared to quality controlled in situ SST data (available from the in situ SST Quality Monitor, iQUAM, companion system) in a consistent manner. A full history of products statistics is retained in L4-SQUAM for time series analysis. L4-SQUAM complements the two other Group for High Resolution SST (GHRSST) tools, the GHRSST Multi Product Ensemble (GMPE) and the High Resolution Diagnostic Data Set (HRDDS) systems, documented in part 1 of this paper and elsewhere, respectively.
Our results reveal significant differences between SST products in coastal and open ocean areas. Differences of > 2 degrees C are often observed at high latitudes partly due to different treatment of the sea-ice transition zone. Thus when an ice flag is available, the intercomparisons are performed in two ways: including and excluding ice-flagged grid points. Such differences are significant and call for a community effort to understand their root cause and ensure consistency between SST products. Future work focuses on including the remaining daily L4 SST products, accommodating for newer L4 SSTs which resolve the diurnal variability and evaluating retrospectively regenerated L4 SSTs to support satellite data reprocessing efforts aimed at generating improved SST Climate Data Records.

AB The magnocellular neurons (MCNs) in the supraoptic nucleus ( SON) of the hypothalamus selectively express either oxytocin (Oxt) or vasopressin (Avp) neuropeptide genes. In this paper we examine the cis-regulatory domains in the Avp gene promoter that are responsible for its cell-type specific expression. AAV vectors that contain various Avp gene promoter deletion constructs using EGFP as the reporter were stereotaxically injected into the rat SON. Two weeks following the injection immunohistochemical assays of EGFP expression from these constructs were done to determine whether the expressed EGFP reporter co-localizes with either the Oxt- or Avp-immunoreactivity in the MCNs. The results identify three major enhancer domains located at -2.0 to -1.5 kbp, -1.5 to -950 bp, and -950 to -543 bp in the Avp gene promoter that regulate the expression in Avp MCNs. The results also show that cell-type specific expression in Avp MCNs is maintained in constructs containing at least 288 bp of the promoter region upstream of the transcription start site, but this specificity is lost at 116 bp and below. Based on these data, we hypothesize that the -288 bp to -116 bp domain contains an Avp MCN specific activator and a possible repressor that inhibits expression in Oxt- MCNs, thereby leading to the cell-type specific expression of the Avp gene only in the Avp-MCNs.

AB Long-lasting mesoscale convective systems (MCSs) may occur in the outer region of tropical cyclones in the western North Pacific, especially in conjunction with the southwest monsoon as in the case of Typhoon Morakot that caused great flooding and landslides in Taiwan. These "outer-MCSs" are linear convective systems that develop from distant rainbands, have a large cold cloud shield, and last more than six hours. These outer-MCSs are important for typhoon rainfall forecasting because of the torrential rainfall when they interact with land and terrain to produce serious flooding that is separate from the rainfall near the center. A total of 109 outer-MCSs that occurred during 1999-2009 are identified using infrared and passive microwave images. About 22% of all typhoons in the western North Pacific have at least one outer-MCS during their life cycle. In 85% of the QuikSCAT oceanic 10-m wind observations of outer-MCSs, positive shear vorticity on the left side of mesoscale surface jets below the stratiform precipitation regions may be contributing to the continuous formation of new convective cells.

TI Origin of the Structural Phase Transition in Li7La3Zr2O12
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID DYNAMICS; AL
AB Garnet-type Li7La3Zr2O12 is a solid electrolyte material for Li-ion battery applications with a low-conductivity tetragonal and a high-conductivity cubic phase. Using density-functional theory and variable cell shape molecular dynamics simulations, we show that the tetragonal phase stability is dependent on a simultaneous ordering of the Li ions on the Li sublattice and a volume-preserving tetragonal distortion that relieves internal structural strain. Supervalent doping introduces vacancies into the Li sublattice, increasing the overall entropy and reducing the free energy gain from ordering, eventually stabilizing the cubic phase. We show that the critical temperature for cubic phase stability is lowered as Li vacancy concentration (dopant level) is raised and that an activated hop of Li ions from one crystallographic site to another always accompanies the transition. By identifying the relevant mechanism and critical concentrations for achieving the high conductivity phase, this work shows how targeted synthesis could be used to improve electrolytic performance.

AB We systematically investigate the effects of divalent anions on the assembly of polyelectrolyte multilayers by fabricating polystyrene sulfonate (PSS)/polyallylamine hydrochloride (PAH) multilayer films from aqueous solutions containing SO42-, HPO42-, or organic dicarboxylate dianions. The chosen concentrations of these anions (i.e., <= 0.05 M) allow us to isolate their effects on the assembly process from those of the polyelectrolyte solubility or solution ionic strength (maintained constant at mu = 1.00 M by added NaCl). Compared to a control film prepared from solutions containing only Cl- anions, stratified multilayers deposited in the presence of dianions exhibit increased UV absorbance, thickness, and roughness. From the dependence of film properties on the solution concentration of SO42- and number of polyelectrolyte layers deposited, we derive a generic model for the PSS/PAH multilayer formation that involves adsorption of PAH aggregates formed in solution via electrostatic interactions of PAH with bridging dianions. Experiments using HPO42- and organic dicarboxylate species of varying structure indicate that the separation, rigidity, and angle between the discrete negatively charged sites in the dianion govern the formation of the PAH aggregates, and therefore also the properties of the multilayer film. A universal linear relationship between film UV absorbance and thickness is observed among all dianion types or concentrations, consistent with the model.

AB Background: Identification of risk factors of acute hepatitis C virus (HCV) infection in Egypt is crucial to develop appropriate prevention strategies.
Methods: We conducted a case-control study, June 2007-September 2008, to investigate risk factors for acute HCV infection in Egypt among 86 patients and 287 age and gender matched controls identified in two infectious disease hospitals in Cairo and Alexandria. Case-patients were defined as: any patient with symptoms of acute hepatitis; lab tested positive for HCV antibodies and negative for HBsAg, HBc IgM, HAV IgM; and 7-fold increase in the upper limit of transaminase levels. Controls were selected from patients' visitors with negative viral hepatitis markers. Subjects were interviewed about previous exposures within six months, including community-acquired and health-care associated practices.
Results: Case-patients were more likely than controls to have received injection with a reused syringe (OR=23.1, CI 4.7-153), to have been in prison (OR=21.5, CI 2.5-479.6), to have received IV fluids in a hospital (OR=13.8, CI 5.3-37.2), to have been an IV drug user (OR=12.1, CI 4.6-33.1), to have had minimal surgical procedures (OR=9.7, CI 4.2-22.4), to have received IV fluid as an outpatient (OR=8, CI 4-16.2), or to have been admitted to hospital (OR=7.9, CI 4.2-15) within the last 6 months. Multivariate analysis indicated that unsafe health facility practices are the main risk factors associated with transmission of HCV infection in Egypt.
Conclusion: In Egypt, focusing acute HCV prevention measures on health-care settings would have a beneficial impact.

AB We present a theoretical description of excitons and positively and negatively charged trions in "giant" CdSe/CdS core-shell nanocrystals (NCs). The developed theory provides the parameters describing the fine structure of excitons in CdSe/CdS core/thick shell NCs as a function of the CdSe/CdS conduction band offset and the CdSe core radius. We have also developed a general theory describing the fine structure of positively charged trions created in semiconductor NCs with a degenerate valence band. The calculations take into account the complex structure of the CdSe valence band and interparticle Coulomb and exchange interaction. Presented in this paper are the CdSe core size and CdSe/CdS conduction band offset dependencies (i) of the positively charged trion fine structure, (ii) of the binding energy of the negatively charged trion, and (iii) of the radiative decay time for excitons and trions. The results of theoretical calculations are in qualitative agreement with available experimental data.

AB Background: Nuclei in the A approximate to 190 mass region show gradual shape changes from prolate through nonaxial deformed shapes and ultimately towards spherical shapes as the Pb region is approached. Exploring how this shape evolution occurs will help us understand the evolution of collectivity in this region.
Purpose: The level scheme of the (192)Aunucleus in A approximate to 190 region was studied in order to deduce its deformations.
Methods: High-spin states of Au-192 have been populated in the W-186(B-11, 5n) reaction at a beam energy of 68 MeV and their gamma decay was studied using the YRAST Ball detector array at the Wright Nuclear Structure Laboratory (WNSL), Yale University.
Results: Based on double and triple gamma-ray coincidence data the level scheme of 192Au has been extended up to I-pi = 32(+) at an excitation energy of similar to 6 MeV.
Conclusion: The results are discussed in the framework of pairing and deformation self-consistent total Routhian surface (TRS) and cranked shell model (CSM) calculations. The comparison of the experimental observations with the calculations indicates that this nucleus takes a nonaxial shape similar to other Au nuclei in this region.

AB Straightforward novel methods for stabilizing, tuning, and controlling a twin Mach-Zehnder interferometer for the purpose of observing a subtle dynamical quantum nonlocality effect in a recent optical experiment are presented and discussed. Weak measurements were required for observing a subtle quantum dynamical nonlocality effect that reveals itself in a change of a weak value. Consequently, emphasis is placed upon describing the approaches to apparatus stabilization and interaction strength control between photons and the apparatus. The details discussed in this paper should be of general interest to experimentalists engaging in weak measurement and weak value research.

AB We perform four numerical magnetohydrodynamic simulations in 2.5 dimensions ( 2.5D) of fast coronal mass ejections (CMEs) and their associated shock fronts between 10 Rs and 300 Rs. We investigate the relative change in the shock standoff distance, Delta, as a fraction of the CME radial half-width, D-OB (i.e., Delta/D-OB). Previous hydrodynamic studies have related the shock standoff distance for Earth's magnetosphere to the density compression ratio (DR; rho(u)/rho(d)) measured across the bow shock. The DR coefficient, k(dr), which is the proportionality constant between the relative standoff distance (Delta/D-OB) and the compression ratio, was semi-empirically estimated as 1.1. For CMEs, we show that this value varies linearly as a function of heliocentric distance and changes significantly for different radii of curvature of the CME's leading edge. We find that a value of 0.8 +/- 0.1 is more appropriate for small heliocentric distances (<30 Rs) which corresponds to the spherical geometry of a magnetosphere presented by Seiff. As the CME propagates its cross section becomes more oblate and the k(dr) value increases linearly with heliocentric distance, such that k(dr) = 1.1 is most appropriate at a heliocentric distance of about 80 Rs. For terrestrial distances (215 Rs) we estimate k(dr) = 1.8 +/- 0.3, which also indicates that the CME cross-sectional structure is generally more oblate than that of Earth's magnetosphere. These alterations to the proportionality coefficients may serve to improve investigations into the estimates of the magnetic field in the corona upstream of a CME as well as the aspect ratio of CMEs as measured in situ.

AB The recent analysis of observations taken with the EUV Imaging Spectrometer and X-Ray Telescope instruments on Hinode suggests that well-constrained measurements of the temperature distribution in solar active regions can finally be made. Such measurements are critical for constraining theories of coronal heating. Past analysis, however, has suffered from limited sample sizes and large uncertainties at temperatures between 5 and 10 MK. Here we present a systematic study of the differential emission measure distribution in 15 active region cores. We focus on measurements in the "inter-moss" region, that is, the region between the loop footpoints, where the observations are easier to interpret. To reduce the uncertainties at the highest temperatures we present a new method for isolating the Fe XVIII emission in the AIA/SDO 94 angstrom channel. The resulting differential emission measure distributions confirm our previous analysis showing that the temperature distribution in an active region core is often strongly peaked near 4 MK. We characterize the properties of the emission distribution as a function of the total unsigned magnetic flux. We find that the amount of high-temperature emission in the active region core is correlated with the total unsigned magnetic flux, while the emission at lower temperatures, in contrast, is inversely related. These results provide compelling evidence that high-temperature active region emission is often close to equilibrium, although weaker active regions may be dominated by evolving million degree loops in the core.

AB We use the weak-curvature, slow-time asymptotics of detonation shock dynamics (DSD) to calculate an intrinsic relation between the normal acceleration, the normal velocity and the curvature of a lead detonation shock for self-sustained detonation waves in condensed phase explosives. The formulation uses the compressible Euler equations for an explosive that is described by a general equation of state with multiple reaction progress variables. The results extend an earlier asymptotic theory for a polytropic equation of state and a single-step reaction rate model discussed by Kasimov (Theory of instability and nonlinear evolution of self-sustained detonation waves. PhD thesis, University of Illinois Urbana-Champaign, Urbana, Illinois) and by Kasimov & Stewart (Phys. Fluids, vol. 16, 2004, pp. 3566-3578). The asymptotic relation is used to study the dynamics of ignition events in solid explosive PBX-9501 and in porous PETN powders. In the case of porous or powdered explosives, two composition variables are used to represent the extent of exothermic chemical reaction and endothermic compaction. Predictions of the asymptotic formulation are compared against those of alternative DSD calculations and against shock-fitted direct numerical simulations of the reactive Euler equations.

AB A mooring section at each end of the Dardanelles Strait was deployed by the Naval Research Laboratory on 28-29 August 2008 and maintained until 11 October 2009. Each section was equipped with two bottom-mounted Barny moorings and a vertical string that together delivered concurrent bottom pressure, temperature, salinity, and almost full-water column current velocity observations. These observations at the mooring sections indicated that on longer timescales (monthly or longer), the exchange through the Dardanelles Strait showed little variability and had a two-layer structure with brackish waters moving approximately southward in the upper layer and more saline Aegean waters flowing roughly northward underneath. On shorter time scales (synoptic), there were pronounced fluctuations in both layers. In the northern section, some manifested as almost simultaneous reversals of the flow direction in both layers with lighter upper-layer waters backing into the Sea of Marmara and dense lower-layer waters moving toward the Aegean Sea. In the southern section, some of the exchange variability consisted of a three-layer flow structure with upper brackish and bottom salty layers moving toward the Aegean Sea and a middle salty layer flowing toward the Sea of Marmara. This three-layer exchange persisted from a day to a week. Synoptic flow variability in the upper layer was partly related to both the along-strait wind stress and the bottom pressure anomaly gradient, while lower-layer current fluctuations were coherent with the bottom pressure anomaly gradient.

AB Background: HIV-associated neurocognitive disorders (HAND) remain prevalent despite improved antiretroviral treatment (ART), and it is essential to have a sensitive and specific HAND screening tool.
Methods: Participants were 200 HIV-infected US military beneficiaries, managed early in the course of HIV infection, had few comorbidities, and had open access to ART. Participants completed a comprehensive, seven-domain (16-test), neuropsychological battery (similar to 120 min); neurocognitive impairment (NCI) was determined using a standardized score derived from demographically adjusted T-scores (global deficit score >= 0.5). Restricting the estimated administration time of the screening battery to < = 20 minutes, we examined the sensitivity and specificity of detecting NCI for all possible combinations of 2-, 3-, and 4- tests from the comprehensive battery.
Results: Participants were relatively healthy (median CD4 count: 546 cells/mm(3)) with 64% receiving ART. Prevalence of NCI was low (19%). The best 2- test screener included the Stroop Color Test and the Hopkins Verbal Learning Test-Revised (11 min; sensitivity = 73%; specificity = 83%); the best 3- test screener included the above measures plus the Paced Auditory Serial Addition Test (PASAT; 16 min; sensitivity = 86%; specificity = 75%). The addition of Action Fluency to the above three tests improved specificity (18 min; sensitivity = 86%; specificity = 87%).
Conclusions: Combinations of widely accepted neuropsychological tests with brief implementation time demonstrated good sensitivity and specificity compared to a time intensive neuropsychological test battery. Tests of verbal learning, attention/working memory, and processing speed are particularly useful in detecting NCI. Utilizing validated, easy to administer, traditional neuropsychological tests with established normative data may represent an excellent approach to screening for NCI in HIV.

ID NANOCRYSTALLINE BATIO3; DIELECTRIC-PROPERTIES; PARTICLES
AB Barium titanate (BaTiO3) is one of the most widely used electronic materials. The origin of changing structural and electronic behavior between larger and smaller nano particles in BaTiO3 has been extensively investigated. Here, the dielectric loss measured for BaTiO3 or BaZrO3 particles in a cavity at audio frequencies (10-10(5) Hz) and low temperatures (5.5-350 K) is reported. Distinct differences were found between small (50-100 nm diameter/cubic) and large (>200 nm diameter/tetragonal at room temperature) BaTiO3 particles. Isochronal relaxation features observed around 20 K showed differing shape and dynamics (50-100 nm particles: broad peak, E-act approximate to 0.04 eV, log(10)(f(pre)(s)) approximate to 14.7; >200 nm particles: sharp peak, E-act approximate to 0.025 eV and log(10)(f(pre)(s)) approximate to 12, with a shoulder). The low-temperature relaxations are attributed to the motion of off-center titanium ions. In support of this identification, low-temperature relaxations were not observed in BaZrO3 nanoparticles. Finally, structural change features were observed at about 180 and 270 K in the larger BaTiO3 particles (rhombohedral at low temperature) but not in the smaller particles (cubic at all temperatures). The results provide a new set of testable bounds that should contribute to the understanding of nanoparticle-sized BaTiO3, in particular, and ferroelectric behavior in perovskites, in general.

AB We apply a phenomenological theory of continua put forth by Rubin, Rosenau and Gottlieb in 1995 to an important class of compressible media. Regarding the material characteristic length coefficient, a, not as constant, but instead as a quadratic function of the velocity gradient, we carry out an in-depth analysis of one-dimensional acoustic travelling waves in inviscid, non-thermally conducting fluids. Analytical and numerical methods are employed to study the resulting waveforms, a special case of which exhibits compact support. In particular, a phase plane analysis is performed; simplified approximate/asymptotic expressions are presented; and a weakly nonlinear, KdV-like model that admits compact travelling wave solutions (TWSs), but which is not of the class K(m, n), is derived and analysed. Most significantly, our formulation allows for compact, pulse-type, acoustic waveforms in both gases and liquids.

AB Flexible bell margins are characteristic components of rowing medusan morphologies and are expected to contribute towards their high propulsive efficiency. However, the mechanistic basis of thrust augmentation by flexible propulsors remained unresolved, so the impact of bell margin flexibility on medusan swimming has also remained unresolved. We used biomimetic robotic jellyfish vehicles to elucidate that propulsive thrust enhancement by flexible medusan bell margins relies upon fluid dynamic interactions between entrained flows at the inflexion point of the exumbrella and flows expelled from under the bell. Coalescence of flows from these two regions resulted in enhanced fluid circulation and, therefore, thrust augmentation for flexible margins of both medusan vehicles and living medusae. Using particle image velocimetry (PIV) data we estimated pressure fields to demonstrate a mechanistic basis of enhanced flows associated with the flexible bell margin. Performance of vehicles with flexible margins was further enhanced by vortex interactions that occur during bell expansion. Hydrodynamic and performance similarities between robotic vehicles and live animals demonstrated that the propulsive advantages of flexible margins found in nature can be emulated by human-engineered propulsors. Although medusae are simple animal models for description of this process, these results may contribute towards understanding the performance of flexible margins among other animal lineages.

TI Na2IrO3 as a Molecular Orbital Crystal
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
AB Contrary to previous studies that classify Na2IrO3 as a realization of the Heisenberg-Kitaev model with a dominant spin-orbit coupling, we show that this system represents a highly unusual case in which the electronic structure is dominated by the formation of quasimolecular orbitals (QMOs), with substantial quenching of the orbital moments. The QMOs consist of six atomic orbitals on an Ir hexagon, but each Ir atom belongs to three different QMOs. The concept of such QMOs in solids invokes very different physics compared to the models considered previously. Employing density functional theory calculations and model considerations we find that both the insulating behavior and the experimentally observed zigzag antiferromagnetism in Na2IrO3 naturally follow from the QMO model.

AB The modulation of electron transport through an ensemble of ligand-stabilized gold nanoclusters by the sorption of vapors is made exceptionally sensitive and selective by terminal carboxylic acid functionalization of the alkanethiol ligand. Of further importance, the directionality of the response (conductance increase or decrease) is strongly dependent on the nanoscale dimensions of the gold core and ligand shell thickness. Films of gold nanoclusters composed of a 2 nm metal core with a 0.5 nm -S(CH2)(5)COOH shell are compared to those based on an 8 nm core and a 1.5 nm -S(CF12)(15)COOH shell with the finding of very strong and selective responses to amine vapors but with a reversal of response in the direction of the conductance transduction. This unexpected result cannot be accommodated by known vapor response transduction mechanisms based on a swelling expansion and a dielectric alteration of the ligand shell to modulate conductance in the ensemble. A speculative new mechanism is proposed on the basis of intercluster nanodomains of low and high dielectric character whose domain dimensions are determined by the ligand molecular structure and dielectric character that can range up to that associated with an ionic capacitance if generated by a vapor interaction.

AB Observations of enhanced growth of melanized fungi under low-dose ionizing radiation in the laboratory and in the damaged Chernobyl nuclear reactor suggest they have adapted the ability to survive or even benefit from exposure to ionizing radiation. However, the cellular and molecular mechanism of fungal responses to such radiation remains poorly understood. Using the black yeast Wangiella dermatitidis as a model, we confirmed that ionizing radiation enhanced cell growth by increasing cell division and cell size. Using RNA-seq technology, we compared the transcriptomic profiles of the wild type and the melanin-deficient wdpks1 mutant under irradiation and non-irradiation conditions. It was found that more than 3000 genes were differentially expressed when these two strains were constantly exposed to a low dose of ionizing radiation and that half were regulated at least two fold in either direction. Functional analysis indicated that many genes for amino acid and carbohydrate metabolism and cell cycle progression were down-regulated and that a number of antioxidant genes and genes affecting membrane fluidity were up-regulated in both irradiated strains. However, the expression of ribosomal biogenesis genes was significantly up-regulated in the irradiated wild-type strain but not in the irradiated wdpks1 mutant, implying that melanin might help to contribute radiation energy for protein translation. Furthermore, we demonstrated that long-term exposure to low doses of radiation significantly increased survivability of both the wild-type and the wdpks1 mutant, which was correlated with reduced levels of reactive oxygen species (ROS), increased production of carotenoid and induced expression of genes encoding translesion DNA synthesis. Our results represent the first functional genomic study of how melanized fungal cells respond to low dose ionizing radiation and provide clues for the identification of biological processes, molecular pathways and individual genes regulated by radiation.

AB Orographic gravity-wave (OGW) parameterizations in models produce waves over subtropical mountain ranges in Australia and Africa that propagate into the stratosphere during austral winter and deposit momentum, affecting weather and climate. Satellite sensors have measured stratospheric GWs for over a decade, yet find no evidence of these waves. So are parameterizations failing here? Here we argue that the short wavelengths of subtropical OGWs place them near or below the detection limits of satellite sensors. To test this hypothesis, we reanalyze nine years of stratospheric radiances from the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite during austral winter, applying new averaging techniques to maximize signal-to-noise and improve thresholds for OGW detection. Deep climatological enhancements in stratospheric OGW variance over specific mountain ranges in Australia and southern Africa are revealed for the first time, which exhibit temporal and vertical variations consistent with predicted OGW responses to varying background winds.

AB We study the effects of discrete, randomly distributed time delays on the dynamics of a coupled system of self-propelling particles. Bifurcation analysis on a mean field approximation of the system reveals that the system possesses patterns with certain universal characteristics that depend on distinguished moments of the time delay distribution. Specifically, we show both theoretically and numerically that although bifurcations of simple patterns, such as translations, change stability only as a function of the first moment of the time delay distribution, more complex patterns arising from Hopf bifurcations depend on all of the moments.

AB A major challenge to the space weather forecasting community is accurate prediction of Coronal Mass Ejections (CMEs) induced Shock Arrival Time (SAT) at Earth's environment. In order to improve the current accuracy, one of the steps is to understand the physical processes of the acceleration and deceleration of a CME's propagation in the heliosphere. We employ our previous study of a three-dimensional (3D) magnetohydrodynamic (MHD) simulation for the evolution of two interacting CMEs in a realistic ambient solar wind during the period 28-31 March 2001 event to illustrate these acceleration and deceleration processes. The forces which caused the acceleration and deceleration are analyzed in detail. The forces which caused the acceleration are the magnetic pressure term of Lorentz force and pressure gradient. On the other hand, the forces which caused the deceleration are aerodynamic drag, the Sun's gravity and the tension of magnetic field. In addition the momentum exchange between the solar wind and the moving CMEs can cause acceleration and deceleration of the CME which are now analyzed. In this specific CME event 28-31 March 2001 we have analyzed those forces which cause acceleration and deceleration of CME with and without interaction with another CME. It shows that there are significant momentum changes between these two interacting CMEs to cause the acceleration and deceleration.

AB We report a study of the valence band dispersion of twisted bilayer graphene using angle-resolved photoemission spectroscopy and ab initio calculations. We observe two noninteracting cones near the Dirac crossing energy and the emergence of van Hove singularities where the cones overlap for large twist angles (> 5 degrees). Besides the expected interaction between the Dirac cones, minigaps appeared at the Brillouin zone boundaries of the moire superlattice formed by the misorientation of the two graphene layers. We attribute the emergence of these minigaps to a periodic potential induced by the moire. These anticrossing features point to coupling between the two graphene sheets, mediated by moire periodic potentials.

AB We sought to determine whether sex had a significant effect on the hematologic and serum chemistry analytes in adult sand rats (Psammomys obesus) maintained under normal laboratory conditions. According to the few data available for this species, we hypothesized that levels of hematologic and serum chemistry analytes would not differ significantly between clinically normal male and female sand rats. Data analysis revealed several significant differences in hematologic parameters between male and female sand rats but none for serum biochemistry analytes. The following hematologic parameters were greater in male than in female sand rats: RBC count, hemoglobin, hematocrit, red cell hemoglobin content, and percentage monocytes. Red cell distribution width, hemoglobin distribution width, mean platelet volume, and percentage lymphocytes were greater in female than in male sand rats. The sex of adult sand rats is a source of variation that must be considered in terms of clinical and research data. The data presented here likely will prove useful in the veterinary medical management of sand rat colonies and provide baseline hematologic and serum chemistry analyte information for researchers wishing to use this species.

AB Introduction: Acute diarrhea continues to be a major cause of morbidity and mortality in children from developing countries. Determination of the frequency of diarrhea in an area, along with the proportion of disease caused by specific enteric agents of different origins, is considered the first step in controlling diarrheal diseases.
Methodology: From 2005 to 2007, a hospital-based surveillance was conducted in two locations in Egypt to determine the causes of acute diarrhea in children younger than 5-years seeking treatment. Five additional enteric viral and parasitic pathogens were tested using commercially-available enzyme immunoassays (EIA) to re-evaluate the prevalence of diarrheal pathogens in undiagnosed cases.
Results: Adenovirus, astrovirus, norovirus and G. lamblia were detected as the sole pathogen in 2% (n=34), 3% (n=56), 9% (n=191) and 7% (n=146) of the cases, respectively. E. histolytica was never detected as the sole pathogen. The percentage of diarrheal cases with a known cause increased significantly, from 48% (n=1,006) to 74% (n=1,568) (P<0.0001).
Conclusion: In our study, the incorporation of immunoassays yielded useful data in identifying pathogens in previously pathogen-negative diarrhea cases.

AB The continuum fusion (CF) methodology produces new classes of multivariate detection algorithms, some of which have been used in spectral applications. CF principles apply to model-based problems in which not all parameter values are known, a common circumstance in hyperspectral operations. We reviewed the principal theoretical and applied CF results devised to date, summarized recent experimental results, and discussed in detail an important class of algorithms that illustrate the design freedom CF affords. Finally, we reviewed the fundamental CF principles as applied to a new category of model parameters only recently considered, involving a distinction in the form of a constraint that is not recognized by older methods.

AB Fundamental shortcomings of ferroelectrics (FEs) are low induced strain and high electric field often required for practical application in actuation, sensors, and acoustics. Although domain engineered FE single crystals deliver an order of magnitude improvement, fatigue remains another drawback in achieving reliable multiple domain switching crucial for memory storage. We demonstrate that under specially compressive stresses FE relaxors exhibit low field induced reversible and sustainable strain associated with FE-FE phase switching and unusual and unexpected lack of fatigue after several millions cycles is believed due to strain accommodation occurring in ferroics. Polarized light microscopy and X-ray diffraction are in a very good agreement with macroscopic observation and phenomenological model confirming proposed transformational path. The phenomena presented in this work are envisioned to be universal in domain engineered ferroics enabling mechanical stress to be used for strain and polarization control of electromechanical energy conversion.

ID ELECTRICITY; HYDROGEN
AB A DC/DC booster circuit was fabricated and tested for use with microbial fuel cells (MFCs) to increase the typical operational voltage (100-300 mV) to a maximum power of >3V. In steady state, the low power DC/DC voltage booster circuit was sustainable, i.e., powered by the MFCs alone, but required an external power source to start (but not needed to maintain) the oscillator. The operating principle and function of each part of the circuit is described. A procedure for determining the optimal set of values for each component in the circuit was established. The performance of the circuit was demonstrated using three Shewanella oneidensis MR-1 based MFCs connected in parallel. The power consumption of the booster circuit was less than 20 mu W, which was less than the output from the three MFCs. After the output capacitor was charged to 5 V. the booster circuit can be powered by the MFCs alone. Under normal operation, the MFCs were able to power the booster circuit and a light emitting diode. (C) 2011 Published by Elsevier Ltd.

AB This paper proposes a fully distributed multiagent-based reinforcement learning method for optimal reactive power dispatch. According to the method, two agents communicate with each other only if their corresponding buses are electrically coupled. The global rewards that are required for learning are obtained with a consensus-based global information discovery algorithm, which has been demonstrated to be efficient and reliable. Based on the discovered global rewards, a distributed Q-learning algorithm is implemented to minimize the active power loss while satisfying operational constraints. The proposed method does not require accurate system model and can learn from scratch. Simulation studies with power systems of different sizes show that the method is very computationally efficient and able to provide near-optimal solutions. It can be observed that prior knowledge can significantly speed up the learning process and decrease the occurrences of undesirable disturbances. The proposed method has good potential for online implementation.

AB Coastal dunes can act as a method of soft coastal protection against inundation and direct impact of waves during storms if they are substantially large enough in volume to withstand erosion without breaching. However, the time evolution of sand dunes under direct wave impact is not well understood and many available models require site specific calibration and have had limited verification at field scales. Here we test three models of varying complexity in their ability to predict both dry beach erosion volumes and dune to a retreat for an East Coast Low storm event that occurred on the Gold Coast, Australia. The process-based model, XBeach, which models the entire profile was able to reproduce both dune toe retreat and dry beach volume, however, was sensitive to calibration parameters. The two parametric models that only modeled erosion above the initial dune toe position were capable of accurately predicting dune toe retreat, however, under-estimated dry beach erosion volumes. With no calibration, the parametric model proposed by Palmsten and Holman (2012) produced the smallest errors of dune toe retreat with mean error in final dune position of 6.6 m, or 18% of the total measured dune retreat. With minimal calibration estimated absolute error in average dune toe retreat was less than 13% of observed retreat for all three models. (C) 2012 Elsevier B.V. All rights reserved.

ID ETIOLOGY
AB Patients are often referred to the emergency department for further evaluation, yet the astute physician will maintain a broad differential to avoid anchoring on prior diagnoses. In this case, a 56-year-old man was referred to our emergency department from the radiology suite secondary to concerns for an "allergic reaction" to prior magnetic resonance imaging contrast. Upon presentation, he was noted to have facial swelling with ruddy appearance and vascular congestion extending to the midchest region; no airway compromise or dyspnea was noted. He had a smoking history and recent diagnosis of brain mass, which, combined with his current appearance, was concerning for superior vena cava syndrome. A chest x-ray that demonstrated right mediastinal mass was ordered, and a computed tomographic scan confirmed compression of the superior vena cava. A brief discussion on the history, etiologies, presentation, and evaluation of superior vena cava syndrome is discussed.

AB Society depends decisively on the availability of infrastructure systems such as energy, telecommunication, transportation, banking and finance, health care and governmental and public administration. Even selective damages of one of these infrastructures may result in disruptions of governmental, industrial or public functions. Vulnerability of infrastructures therefore provides spectacular leverage for natural disasters as well as criminal and terrorist actions. Threats and risks are part of the technological, economical, and societal development. This article focuses on the development and characterization of an integrative risk-management which, from the perspective of "resilient systems", can be seen as an innovative and pro-active crisis management approach dealing with the increasing amount of complexity in societies in a comprehensive, agile and adaptive way.

AB A through-dielectric switched-antenna-array radar imaging system is shown that produces near real-time imagery of targets on the opposite side of a lossy dielectric slab. This system operates at S-band, provides a frame rate of 0.5 Hz, and operates at a stand-off range of 6 m or greater. The antenna array synthesizes 44 effective phase centers in a linear array providing lambda/2 element-to-element spacing by time division multi-plexing the radar's transmit and receive ports between 8 receive elements and 13 transmit elements, producing 2D (range vs. cross-range) imagery of what is behind a slab. Laboratory measurements agree with simulations, the air-slab interface is range gated out of the image, and target scenes consisting of cylinders and soda cans are imaged through the slab. A 2D model of a slab, a cylinder, and phase centers shows that blurring due to the slab and bistatic phase centers on the array is negligible when the radar sensor is located at stand-off ranges of 6 m or greater.

AB Background: Risk of abnormal bleeding in surgery patients prescribed serotonin reuptake inhibitors (SRIs) is unclear. Considering the quantity of literature on abnormal gastrointestinal (GI) bleeding with SRIs, relatively little exists on SRI bleeding risks in surgical procedures. We investigated whether SRIs increase the risk of surgical bleeding in patients undergoing knee and hip total joint replacement. Methods: RA retrospective case-control study was conducted among subjects undergoing primary total hip and knee replacement surgeries from January 2005 to March 2011 at a single institution. The experimental group was defined by utilization of SRIs at the time of surgery (the independent variable). The control group was matched for age, sex, ethnicity, and type of surgery (hip or knee). Any case with preoperative hematocrit <30, platelets <100,000; abnormal prothrombin time, partial-prothrombin time, and international normalized ratio (INR), primary bleeding disorder, medical conditions, or medications associated with increased bleeding was excluded. All cases were randomly selected. Results: RA total of 194 subjects (hip 104, knee 90) were included. Statistical analysis was performed on the SRI group (n = 71) and the control, non-SRI group (n = 123). No difference was found between the groups in estimated blood loss, hemoglobin, hematocrit, platelets, PT, PTT, and INR from preoperative to postoperative day I, 2, and 3. Furthermore, no subjects in either group required blood transfusions. Conclusion: SRIs were not associated with increased risk of bleeding in primary knee or hip replacement surgeries in this study. The hypothesis that SRIs increase the risk of bleeding based on presumptions about their action on platelet aggregation is uncertain and warrants further study. (Psychosomatics 2012; 53:559-565)

CONTRACTURE; IMPROVEMENT; LAXITY; DEVICE
AB Background: Skin compromised by traumatic scars and contractures can manifest decreased resistance to shearing and other forces, while increased tension and skin fragility contribute to chronic erosions and ulcerations. Chronic wounds possess inflammatory mediator profiles and other characteristics, such as the presence of biofilms, that can inhibit healing.
Observations: Three patients with multiple traumatic scars related to blast injuries initiated a course of ablative fractional laser therapy for potential mitigation of contractures, poor pliability, and textural irregularity. Patients also had chronic focal erosions or ulcerations despite professional wound care. All patients experienced incidental rapid healing of their chronic wounds within 2 weeks of their initial ablative fractional laser treatment. Healing was sustained throughout the treatment course and beyond and was associated with gradual enhancements in scar pliability, texture, durability, and range of motion.
Conclusions: The unique pattern of injury associated with ablative fractional laser treatment may have various potential wound-healing advantages. These advantages include the novel concept of photomicrodebridement, including biofilm disruption and the stimulation of de novo growth factor secretion and collagen remodeling. If confirmed, ablative fractional resurfacing could be a potent new addition to traditional wound and scar treatment paradigms. Arch Dermatol. 2012;148(11):1289-1293

ID MOLECULAR-CRYSTALS; DENSITY
AB Spiro-cyclic compounds frequently have screw-type symmetry (C-2) and are therefore optically active even though they do not contain an asymmetric carbon atom. (R/S)-1,6-Dinitro-3,8-dioxa-1,6-diazaspiro[4.4]nonane-2,7-dione is such a molecule. A blind crystal structure prediction study of structures containing one molecule in the asymmetric unit and considering all 230 space groups was undertaken using a dispersion-corrected density functional approach, which found a packing that matched the experimental structure of the (R/S) form as the lowest energy packing alternative. The densities of (R/S); and (S)- or (R)-1,6-dinitro-3,8-dioxa-1,6-diazaspiro[4.4]nonane-2,7-dione calculated for the Optimized experimental crystal structures confirmed that there is a small difference in the densities of the racemate and the optically active compound, with the optically active material being slightly more dense (1.875 versus 1.842 g/cm(3)). (R/S)-1,6-Dinitro-3,8-dioxa-1,6-diazaspiro[4.4]nonane-2,7-dione was synthesized as previously described Synthesis of the pure (S)-stereoisomer was accomplished by resolution of the racemic dithiourethane using a previously described method, followed by reaction of the pure enantiomer with acetyl nitrate. The absolute configuration of the l-3,8-dioxa-1,6-diazaspiro[4.4]nonane-2,7-dithione was established as (S)- by redetermining the crystal structure at 150 K. The racemate crystallizes in space group P2(1)/n with a density of 1.835 g/cm(3) (296 K). The (S)-compound crystallizes in space group P2(1)2(1)2(1) with a density of 1.854 g/cm(3) (296 K). This is the first demonstration of a difference in the density between the racemic mixture and the optically pure stereoisomer of an energetic material. It is also an apparent violation of Wallach's rule, which states that racemic crystals tend to be denser than their optically active counterparts.

AB When introduced in the 1990s, immunization with DNA plasmids was considered potentially revolutionary for vaccine development, particularly for vaccines intended to induce protective CD8 T cell responses against multiple antigens. We conducted, in 1997-1998, the first clinical trial in healthy humans of a DNA vaccine, a single plasmid encoding Plasmodium falciparum circumsporozoite protein (PfCSP), as an initial step toward developing a multi-antigen malaria vaccine targeting the liver stages of the parasite. As the next step, we conducted in 2000-2001 a clinical trial of a five-plasmid mixture called MuStDO5 encoding pre-erythrocytic antigens PfCSP, PfSSP2/TRAP, PfEXP1, PfLSA1 and PfLSA3. Thirty-two, malaria-naive, adult volunteers were enrolled sequentially into four cohorts receiving a mixture of 500 mu g of each plasmid plus escalating doses (0, 20, 100 or 500 mu g) of a sixth plasmid encoding human granulocyte macrophage-colony stimulating factor (hGM-CSF). Three doses of each formulation were administered intramuscularly by needle-less jet injection at 0, 4 and 8 weeks, and each cohort had controlled human malaria infection administered by five mosquito bites 18 d later. The vaccine was safe and well-tolerated, inducing moderate antigen-specific, MHC-restricted T cell interferon-gamma responses but no antibodies. Although no volunteers were protected, T cell responses were boosted post malaria challenge. This trial demonstrated the MuStDO5 DNA and hGM-CS F plasmids to be safe and modestly immunogenic for T cell responses. It also laid the foundation for priming with DNA plasmids and boosting with recombinant viruses, an approach known for nearly 15 y to enhance the immunogenicity and protective efficacy of DNA vaccines.

AB For electro-optic modulators, traveling wave designs are implemented due to the long interaction area necessary to efficiently modulate a signal with low voltages as a result of LiNbO3's modest electro-optic coefficient (r(33) = 30 pm/V). However, with metamaterial inspired, electrically small resonator antennas, high field enhancements can be produced which allow the modulation of optical signals directly from the antennas, bypassing the need for a separate modulator [1]. For this work, Laser Direct Write (LDW) proved to be a useful tool in fabricating various meta-antenna array structures. The additive techniques of laser direct write, coupled with more traditional micromachining, have allowed the quick fabrication of these resonator meta-antennas so that the desired specifications, including resonant frequency and field enhancement, can be tested quickly and appropriate updates to the design can be made. This allows a designer to shift the resonant frequency and increase the field enhancement necessary to get the required device performance. The Laser Induced Forward Transfer (LIFT) technique was used initially for lower frequency designs (X-band); however, Laser Decal Transfer (LDT) was used subsequently for designs with higher frequencies by employing a digital mirror device to modulate the image of the beam. The resulting designs showed good fabrication consistency in terms of resonant frequency and comparable field enhancement to resonators fabricated through traditional lithography.

AB Thick-film electrodes (LiCoO2 cathode and carbon anode) are laser-printed onto metallic current collectors for fabricating Li-ion microbatteries. Microbatteries fabricated with these laser-printed thick-film electrodes demonstrate a significantly higher discharge capacity and power density than those made by sputter-deposited thin-film techniques. This increased performance is attributed to the porous structure of the laser-printed electrodes that allows improved ionic and electronic transport through the thick electrodes (up to similar to 100 mu m) without a significant increase in internal resistance. Laser structuring process is applied to increase active surface area of the laser-printed LiCoO2 cathode films for improving cycle stability of microbatteries at high charging/discharging currents. Laser structuring parameters, including laser pulse number and laser fluence, are optimized for improving surface morphology of the films. DOI:10.2961/jlmn.2012.03.0016

AB Objectives: A preponderance of literature supports the safety of office-based flexible endoscopic procedures of the upper aerodigestive tract; however, until recently there were no data regarding hemodynamic stability during these procedures. A recent study showed intraprocedure changes in patients' hemodynamic parameters, raising the concern that perhaps patients should be monitored during these procedures. The aim of our study was to determine whether physiologically significant alterations in vital signs occur during office-based flexible endoscopic procedures.
Methods: We performed a retrospective review of 100 consecutive patients who underwent office-based flexible endoscopic procedures of the upper aerodigestive tract from July 2010 to October 2011. Baseline values and the maximal changes in systolic blood pressure, diastolic blood pressure, heart rate, and oxygen saturation were recorded and compared.
Results: One hundred consecutive patients were included in the study. Twenty-one patients (21%) had severe hypertension and 40 patients (40%) had tachycardia during the procedure. The mean change overall in systolic blood pressure was 26.2 mm Hg (p < 0.001), the mean change in diastolic blood pressure was 13.9 mm Hg (p < 0.001), the mean change in heart rate was 16.6 beats per minute (p < 0.001), and the mean change in oxygen saturation was 1.6% (p < 0.001). These changes were significant. On further breakdown into groups, patients over 50 years of age and patients who were undergoing esophageal or laser procedures had significant elevations in heart rate (p = 0.01 and p = 0.04, respectively). An elevation in diastolic blood pressure was also significant in patients who were undergoing esophageal or laser procedures (p = 0.04 for both).
Conclusions: These data concur with those of the previous report that found potentially significant hemodynamic changes during office-based procedures. Although preliminary, our findings suggest that it may be wise to monitor vital signs in patients over 50 years of age and patients who are undergoing an esophageal or laser procedure who are at risk for complications that could arise from tachycardia and hypertension.

AB Relative to the high-sulfur diesel in use for decades, the U.S. Navy is facing exposure to new fuels that may behave differently in the marine environment. This laboratory work investigated the effects of biofouling and seawater exposure to high-sulfur diesel, ultralow-sulfur diesel, Fischer-Tropsch synthetic diesel, fatty acid methyl ester (FAME) biodiesel, and hydrotreated renewable diesel fuels. Bulk chemical changes were not detectable under the laboratory test conditions, but changes in fuel lubricity, controlled by traces of polar compounds in fuel, were detectable in several fuels by both physical and chemical testing. A marine microbial assemblage rapidly metabolized the lubricity improver (as C-14-linoleic acid) as it partitioned to seawater from hydrotreated renewable and ultralow-sulfur diesel fuels. Equipment dependent upon fuel lubricity, such as fuel pumps and fuel injectors, may be at risk when new fuels enter use in the near future, given that certain U.S. Navy ship classes store fuel wet, in seawater-compensated tanks. Our results have implications for improperly stored fuels, as well.

AB An analytic methodology was developed to predict the fatigue life of a structure experiencing stationary, Gaussian random vibration excitation. This method allows the estimation of fatigue life using a frequency domain method, where only the input power spectral density and damping factor are required. The methodology uses linear elastic fracture mechanics for fatigue crack propagation and accounts for the frequency shifting that occurs due to fatigue crack evolution. Good results have been obtained comparing the analytic model to both finite element analysis (FEA) and experimental results, for mild-steel cantilever beams.

AB Objective: To evaluate the current evidence regarding the safety and efficacy of medical management for deep neck abscesses in children.
Data sources: Pubmed and Embase databases accessed 3/27/2012.
Review methods: An a priori protocol defining inclusion and exclusion criteria was developed to identify all articles addressing medical therapy of pediatric deep neck abscesses where details regarding diagnostic criteria, specifics of medical therapy and definitions of failure were presented. The search included electronic databases to identify candidate articles as well as a manual crosscheck of references. The level of evidence was assessed and data extracted by three authors independently. Data were pooled using a random effects model due to significant study heterogeneity.
Results: Eight articles met inclusion criteria. The overall level of evidence was grade C. There was significant heterogeneity among the studies (I-2=98.8%; p<.001). However, each article uniformly presented cases suggesting that medical therapy may be a viable alternative to surgical drainage in some patients. The pooled success rate of medical therapy in avoiding surgical drainage in children with deep neck infections was 0.517 (95%CI: 0.335, 0.700). When patients taken immediately to surgery were excluded and patients were placed on author defined medical protocols, the success rate increased to 0.951 (95%CI: 0.851, 1.051). Subgroup analysis by duration of intravenous antibiotic trial greater than 48 h demonstrated a pooled success rate of 0.740 (95%CI: 0.527, 0.953).
Conclusion: The current literature suggests medical management may be a safe alternative to surgical drainage of deep neck abscesses in children. However, the level of evidence lacks strength and further investigation is warranted. Published by Elsevier Ireland Ltd.

AB Congenital laryngeal atresia is a rare cause of respiratory distress of the newborn. The defect may be isolated or occur in association with other congenital abnormalities, notably the presence of a tracheoesophageal fistula, esophageal atresia, encephalocele, or Congenital High Airway Obstructive Syndrome (CHAOS). We present the case of a newborn with no identified intrapartum abnormalities with respiratory distress at birth secondary to near-complete laryngeal atresia. Management included tracheostomy, repeated endoscopic incisions, and serial balloon dilatations employing the topical use of Mitomycin C. Seven year follow-up was significant for mobilization of the true vocal cords bilaterally, as well as successful decannulation. Published by Elsevier Ireland Ltd.

AB Boundary-layer separation control with pulsed vortex generator jets has been studied on a very high lift, low-pressure turbine airfoil in the presence of unsteady wakes. Experiments were done in a linear cascade under low (0.6%) and high (4%) freestream-turbulence conditions at low Reynolds numbers. Wakes were produced from moving rods upstream of the cascade. The vortex generator jets were injected at the beginning of the adverse-pressure-gradient region with maximum jet velocity equal to the local freestream velocity and a jet duty cycle of 10%. Several different timings of the vortex generator jets with respect to the wakes were considered. In cases without vortex generator jets, the boundary layer momentarily reattached in response to the wake passing, but separated between wakes. The vortex generator jets also caused reattachment, and if the vortex-generator-jet pulsing frequency was sufficiently high, separation was largely suppressed for the full wake passing cycle. The timing of the vortex generator jets with respect to the wakes was not very important. The jet pulsing frequency needed for separation control was about the same as found previously in cases without wakes. The background freestream-turbulence effect was negligible in the presence of the larger wake and vortex-generator-jet disturbances.

AB OBJECTIVES: An advanced hemostatic dressing, Rapid Trauma Hemostat (RTH), was developed using nano-engineered inorganic nanofibers with hemostatic surface properties.
METHODS: Yorkshire swine were treated with RTH or Combat Gauze (CBG) to stop bleeding from either an arterial puncture (G-RTH and G-CBG) or a liver lobe laceration (L-RTH and L-CBG). All animals received 500 mL of Hextend at 10 minutes after injury and were monitored for a total time of 180 minutes.
RESULTS: Uncontrolled hemorrhage was similar in all animals in both models and was immediately controlled with the application of either dressing. After blood pressure was restored with fluid resuscitation, the RTH hemostatic treatment was less effective than CBG in the groin (puncture) model (rebleeding incidence, four of seven for G-RTH vs. one of seven for G-CBG; p = 0.034) but showed similar efficacy in the liver injury model (lower pressure bleeding). Interestingly, RTH exhibited a trend for higher efficacy in terms of hemostatic plug formation at the end of the experiment (no bleeding occurred after dressing removal) in the liver injury model.
CONCLUSION: Overall, RTH was not as effective at stopping high-shear rate (arterial) bleeding, but it presented some advantages for intracavitary treatment with potential for long-term evacuation. (J Trauma Acute Care Surg. 2012;73:1180-1187. Copyright (c) 2012 by Lippincott Williams & Wilkins)

AB The flat spectrum radio quasar (FSRQ) PKS 2123-463 was associated in the first Fermi-Large Area Telescope (LAT) source catalogue with the gamma-ray source 1FGL J2126.1-4603, but when considering the full first two years of Fermi observations, no gamma-ray source at a position consistent with this FSRQ was detected, and thus PKS 2123-463 was not reported in the second Fermi-LAT source catalogue. On 2011 December 14 a gamma-ray source positionally consistent with PKS 2123-463 was detected in flaring activity by Fermi-LAT. This activity triggered radio-to-X-ray observations by the Swift, Gamma-ray Optical/Near-Infrared Detector (GROND), Australia Telescope Compact Array (ATCA), Ceduna and Seven Dishes Karoo Array Telescope (KAT-7) observatories. Results of the localization of the gamma-ray source over 41 months of Fermi-LAT operation are reported here in conjunction with the results of the analysis of radio, optical, ultraviolet (UV) and X-ray data collected soon after the gamma-ray flare. The strict spatial association with the lower energy counterpart together with a simultaneous increase of the activity in optical, UV, X-ray and gamma-ray bands led to a firm identification of the gamma-ray source with PKS 2123-463. A new photometric redshift has been estimated as z = 1.46 +/- 0.05 using GROND and Swift Ultraviolet/Optical Telescope (UVOT) observations, in rough agreement with the disputed spectroscopic redshift of z = 1.67. We fit the broad-band spectral energy distribution with a synchrotron/external Compton model. We find that a thermal disc component is necessary to explain the optical/UV emission detected by Swift/UVOT. This disc has a luminosity of similar to 1.8 x 10(46) erg s(-1), and a fit to the disc emission assuming a Schwarzschild (i.e. non-rotating) black hole gives a mass of similar to 2 x 10(9) M-circle dot. This is the first black hole mass estimate for this source.

AB In May of 2011, an enteroaggregative Escherichia coli O104:H4 strain that had acquired a Shiga toxin 2-converting phage caused a large outbreak of bloody diarrhea in Europe which was notable for its high prevalence of hemolytic uremic syndrome cases. Several studies have described the genomic inventory and phylogenies of strains associated with the outbreak and a collection of historical E. coli O104: H4 isolates using draft genome assemblies. We present the complete, closed genome sequences of an isolate from the 2011 outbreak (2011C-3493) and two isolates from cases of bloody diarrhea that occurred in the Republic of Georgia in 2009 (2009EL-2050 and 2009EL-2071). Comparative genome analysis indicates that, while the Georgian strains are the nearest neighbors to the 2011 outbreak isolates sequenced to date, structural and nucleotide-level differences are evident in the Stx2 phage genomes, the mer/tet antibiotic resistance island, and in the prophage and plasmid profiles of the strains, including a previously undescribed plasmid with homology to the pMT virulence plasmid of Yersinia pestis. In addition, multiphenotype analysis showed that 2009EL-2071 possessed higher resistance to polymyxin and membrane-disrupting agents. Finally, we show evidence by electron microscopy of the presence of a common phage morphotype among the European and Georgian strains and a second phage morphotype among the Georgian strains. The presence of at least two stx2 phage genotypes in host genetic backgrounds that may derive from a recent common ancestor of the 2011 outbreak isolates indicates that the emergence of stx2 phage-containing E. coli O104: H4 strains probably occurred more than once, or that the current outbreak isolates may be the result of a recent transfer of a new stx2 phage element into a pre-existing stx2-positive genetic background.

AB We have previously described the application of novel porous organosilicate materials to the preconcentration of nitroenergetic targets from aqueous solution prior to HPLC analysis. The performance of the sorbents and the advantages of these types of materials over commercially available solid phase extraction sorbents have been demonstrated. Here, the development of systems for application of those sorbents to in situ monitoring is described. Considerations such as column pressure, particulate filtration, and component durability are discussed. The diameter of selected column housings, the sorbent bed depth, and the frits utilized significantly impact the utility of the sorbent columns in the prototype system. The impact of and necessity for improvements in the morphological characteristics of the sorbents as they relate to reduction in column pressure are detailed. The results of experiments utilizing a prototype system are presented. Data demonstrating feasibility for use of the sorbents in preconcentration prior to ion mobility spectrometry is also presented.

AB Coronal holes can produce several types of solar wind with a variety of compositional properties, depending on the location and strength of the heating along their open magnetic field lines. High-speed wind is associated with (relatively) slowly diverging flux tubes rooted in the interiors of large holes with weak, uniform footpoint fields; heating is spread over a large radial distance, so that most of the energy is conducted outward and goes into accelerating the wind rather than increasing the mass flux. In the rapidly diverging open fields present at coronal hole boundaries and around active regions, the heating is concentrated at low heights and the temperature maximum is located near the coronal base, resulting in high oxygen freezing-in temperatures and low asymptotic wind speeds. Polar plumes have a strong additional source of heating at their bases, which generates a large downward conductive flux, raising the densities and enhancing the radiative losses. The relative constancy of the solar wind mass flux at Earth reflects the tendency for the heating rate in coronal holes to increase monotonically with the footpoint field strength, with very high mass fluxes at the Sun offsetting the enormous flux-tube expansion in active region holes. Although coronal holes are its main source, slow wind is also released continually from helmet streamer loops by reconnection processes, giving rise to plasma blobs (small flux ropes) and the heliospheric plasma sheet.

AB The phase behavior and ionic conductivity of tetraethylammonium bis(trifluoromethane-sulfonyl)imide (Et4NTFSI) salt mixtures with LiTFSI have been examined. In addition, the phase behavior and crystal structure of neat LiTFSI is also reported. Two (1-x) Et4NTFSI-(x) LiTFSI (x = 0.50 and 0.67, where x is the mol fraction) mixed-salt crystalline phases form. Large variations in ionic conductivity are observed; these are attributed to solid-solid phase transitions of the neat Et4NTFSI salt creating disordered plastic crystalline phases and the formation of a low-melting eutectic composition between the neat Et4NTFSI salt and the 1/1 Et4NTFSI/LiTFSI (x = 0.50) phase. Although Et4NTFSI and LiTFSI melt at 102 and 234 degrees C, respectively, the two salts form a eutectic system with a melting temperature of 32 degrees C. Based upon the findings reported, a new conductivity mechanism is proposed for plastic crystalline salt-lithium salt electrolytes which is not ascribed to solid-state diffusion/conduction.

AB We have evaluated the energetics of 38 solar eruptive events observed by a variety of spacecraft instruments between 2002 February and 2006 December, as accurately as the observations allow. The measured energetic components include: (1) the radiated energy in the Geostationary Operational Environmental Satellite 1-8 angstrom band, (2) the total energy radiated from the soft X-ray (SXR) emitting plasma, (3) the peak energy in the SXR-emitting plasma, (4) the bolometric radiated energy over the full duration of the event, (5) the energy in flare-accelerated electrons above 20 keV and in flare-accelerated ions above 1MeV, (6) the kinetic and potential energies of the coronal mass ejection (CME), (7) the energy in solar energetic particles (SEPs) observed in interplanetary space, and (8) the amount of free (non-potential) magnetic energy estimated to be available in the pertinent active region. Major conclusions include: (1) the energy radiated by the SXR-emitting plasma exceeds, by about half an order of magnitude, the peak energy content of the thermal plasma that produces this radiation; (2) the energy content in flare-accelerated electrons and ions is sufficient to supply the bolometric energy radiated across all wavelengths throughout the event; (3) the energy contents of flare-accelerated electrons and ions are comparable; (4) the energy in SEPs is typically a few percent of the CME kinetic energy (measured in the rest frame of the solar wind); and (5) the available magnetic energy is sufficient to power the CME, the flare-accelerated particles, and the hot thermal plasma.

AB The Fermi Large Area Telescope (Fermi-LAT, hereafter LAT), the primary instrument on the Fermi Gamma-ray Space Telescope (Fermi) mission, is an imaging, wide field-of-view, high-energy gamma-ray telescope, covering the energy range from 20 MeV to more than 300 GeV. During the first years of the mission, the LAT team has gained considerable insight into the in-flight performance of the instrument. Accordingly, we have updated the analysis used to reduce LAT data for public release as well as the instrument response functions (IRFs), the description of the instrument performance provided for data analysis. In this paper, we describe the effects that motivated these updates. Furthermore, we discuss how we originally derived IRFs from Monte Carlo simulations and later corrected those IRFs for discrepancies observed between flight and simulated data. We also give details of the validations performed using flight data and quantify the residual uncertainties in the IRFs. Finally, we describe techniques the LAT team has developed to propagate those uncertainties into estimates of the systematic errors on common measurements such as fluxes and spectra of astrophysical sources.

AB Gaussian process emulators are a powerful tool for understanding complex geophysical simulators, including oceanic and atmospheric general circulation models. Concern has been raised about their ability to emulate complex nonlinear systems. For the first time, using the simple Stommel model, the way in which emulators can reasonably represent the full sampling space of an extreme nonlinear, bimodal system is illustrated. This simple example also shows how an emulator can help to elucidate interactions between parameters. The ideas are further illustrated with a second, more realistic, intermediate complex climate simulator. The paper describes what is meant by an emulator, the methodology of emulators, how emulators can be assessed, and why they are useful. It is shown how simple emulators can be useful to explore the parameter space (initial conditions, process parameters, and boundary conditions) of complex computer simulators, such as ocean and climate general circulation models, even when simulator outcomes contain steps in the response.

AB Blast related traumatic brain injury (TBI) has been a major cause of injury in the wars in Iraq and Afghanistan. A striking feature of the mild TBI (mTBI) cases has been the prominent association with post-traumatic stress disorder (PTSD). However, because of the overlapping symptoms, distinction between the two disorders has been difficult. We studied a rat model of mTBI in which adult male rats were exposed to repetitive blast injury while under anesthesia. Blast exposure induced a variety of PTSD-related behavioral traits that were present many months after the blast exposure, including increased anxiety, enhanced contextual fear conditioning, and an altered response in a predator scent assay. We also found elevation in the amygdala of the protein stathmin 1, which is known to influence the generation of fear responses. Because the blast overpressure injuries occurred while animals were under general anesthesia, our results suggest that a blast-related mTBI exposure can, in the absence of any psychological stressor, induce PTSD-related traits that are chronic and persistent. These studies have implications for understanding the relationship of PTSD to mTBI in the population of veterans returning from the wars in Iraq and Afghanistan.

AB The majority of engineering optimization problems (design, identification, design of controlled systems, optimization of large-scale systems, operational development of prototypes, and so on) are essentially multicriteria. The correct determination of the feasible solution set is a major challenge in engineering optimization problems. In order to construct the feasible solution set, a method called PSI (Parameter Space Investigation) has been created and successfully integrated into various fields of industry, science, and technology. Owing to the PSI method, it has become possible to formulate and solve a wide range of multicriteria optimization problems. In addition to giving an overview of the PSI method, this paper also describes the methods for approximation of the feasible and Pareto optimal solution sets, identification, decomposition, and aggregation of the large-scale systems.

The purpose of this prospective study was to identify and characterize the unique cytokine and chemokine profile associated with the development of HO as it pertained to the systemic inflammatory response after penetrating combat-related trauma.
Methods: Patients with high-energy penetrating extremity wounds were prospectively enrolled. Surgical debridement along with the use of a pulse lavage and vacuum-assisted-closure device was performed every 48-72 hours until definitive wound closure. Wound bed tissue biopsy, wound effluent, and serum were collected before each debridement. Effluent and serum were analyzed for 22 relevant cytokines and chemokines. Tissue was analyzed quantitatively for bacterial colonization. Correlations between specific wound and patient characteristics were also analyzed. The primary clinical outcome measure was the formation of HO as confirmed by radiographs at a minimum of 2 months of follow-up.
Results: Thirty-six penetrating extremity war wounds in 24 patients were investigated. The observed rate of HO in the study population was 38%. Of the 36 wounds, 13 (36%) demonstrated HO at a minimum follow-up of 2 months. An elevated injury severity score was associated with the development of HO (P = 0.006). Wound characteristics that correlated with the development of HO included impaired healing (P = 0.005) and bacterial colonization (P < 0.001). Both serum (interleukin-6, interleukin-10, and MCP-1) and wound effluent (IP-10 and MIP-1 alpha) cytokine and chemokine bioprofiles were individually associated and suggestive of the development of HO (P < 0.05).
Conclusions: A severe systemic and wound-specific inflammatory state as evident by elevated levels of inflammatory cytokines, elevated injury severity score, and bacterial wound colonization is associated with the development of HO. These findings suggest that the development of HO in traumatic combat-related wounds is associated with a hyper-inflammatory systemic response to injury.

insights using a focused ion beam

AB Focused ion beam (FIB) milling permits the accurate extraction of ultrathin (c. 100nm) cross sectional lamellae from microfossils found in geological thin sections. Subsequent TEM analysis of these lamellae can provide unique insights into the ultrastructure, chemistry and taphonomy of Precambrian microfossils at the micrometer to nanometer scale. Combining serial FIB milling with SEM imaging extends this capability to three dimensional (3D) tomographic reconstruction and visualization of Precambrian microfossils, revealing information not available in light microscopy.
Here we apply these techniques to two iconic silicified microfossil assemblages, from the similar to 3400 Ma Strelley Pool Formation of Western Australia and the similar to 1900 Ma Gunflint Formation of Canada. All the examined microfossils have carbonaceous walls surrounded by pure silica. Impregnation of microfossil walls by nano-grains of silica is common, together with variable degrees of wall displacement and replacement by silica. All microfossils are rigidly preserved in 3D and show little or no folding or compression. However, there are also notable differences in taphonomic preservation. Our examples of the spheroidal Gunflint microfossil Huroniospora showed the highest fidelity of preservation with a continuous carbonaceous wall fossilized by spheroidal nano-silica grains that resemble those found on bacterial surfaces in modern silicifying hot-spring environments. The nucleation of these silica nano-spheres on the microfossil walls has induced an artificial 'saw-tooth-like' ridged wall texture that may subsequently hinder species-level identification. The Strelley Pool microfossils in comparison show a lower fidelity of preservation with small parts of the microfossil walls completely replaced by silica, plus extensive recrystallization of spheroidal silica nano-grains to angular micro-quartz. Our examples of the sheath-like filamentous Gunflint microfossil Siphonophycus showed the lowest fidelity of preservation with many gaps in the carbonaceous walls and significant redistribution of carbon by recrystallizing silica grains. A model is presented to explain these observations.
Criteria for distinguishing highly probable microfossils from non-cellular carbonaceous microstructures (e.g., botryoids and grain coatings) using FIB-based imaging are put forward for the first time here, using examples drawn from the Strelley Pool Formation and comparisons with younger Gunflint material.
The combined in situ techniques of FIB-TEM and FIB-SEM nano-tomography potentially provide a wealth of new nano-scale information regarding the biogenicity, antiquity and taphonomy of Precambrian microfossils. However, the destructive nature of both techniques makes their application to unique palaeontological specimens problematical. (C) 2012 Elsevier B.V. All rights reserved.

ID BEHAVIORAL-APPROACH; COCAINE ABSTINENCE
AB Objective. To provide insight on the feasibility and utility of implementing a broad based incentive program for health within the Military Health System (MHS).
Method. Published studies, articles, and information on the use of financial incentives in the military setting and to promote healthy behaviors were reviewed.
Results. Health care costs in the MHS have more than doubled over the past decade. The high prevalence of modifiable risk behaviors such as tobacco abuse, physical inactivity and obesity and their associated chronic diseases are accounting for a significant percentage of the growth. One evidence-based approach to address this issue would be the implementation of a broad based incentive program for health whereby all MHS beneficiaries would be eligible to receive some type of financial remuneration for meeting positive personal health metrics (e.g. not smoking or a normal body mass index). This approach if designed appropriately has the potential to have a high level of acceptance within the current beneficiary population since financial incentives are already used widely in the military to help meet overall manpower requirements.
Conclusion. The use of a MHS wide financial incentives program to instill healthy behaviors in beneficiaries' may be an effective means to curb rising healthcare cost. (C) 2012 Elsevier Inc. All rights reserved.

ID SHOCK-ASSOCIATED NOISE; LARGE-SCALE STRUCTURES; MIXING LAYER; FIELD;
TABS; FCT
AB This paper describes a joint experimental and computational study of the flowfield and acoustics of conical convergent divergent nozzles such as those found on high-performance military aircraft. The influence of chevrons on a nozzle with an area ratio corresponding to a design Mach number of 1.5 (design pressure ratio of 3.67) is examined. The nozzle is tested at its design condition, at overexpanded conditions with pressure ratios of 2.5, 3.0, and 3.5 and at underexpanded conditions with pressure ratios of 4.0, 4.5, and 5.0. Each case is compared to a baseline nozzle at the same condition without chevrons. Shadowgraph images show that chevrons reduce the shock cell spacing. Near-field acoustic measurements show that sources of broadband shock-associated noise move downstream when chevrons are applied. Near-field acoustics also reveal that, for supersonic jets, chevrons produce significant noise near the nozzle exit across the whole range of frequencies. Far-field acoustic measurements show that the application of chevrons reduces screech, broadband shock-associated noise, and mixing noise, except for frequencies above the broadband shock-associated noise peak for overexpanded and perfectly expanded conditions.

AB Linear polarization of the clear daytime sky has often been measured as a spectrally integrated or quasi-monochromatic variable, but seldom as a spectral one. So we use a hyperspectral imaging system to measure skylight polarization at high spectral and angular resolutions for clear and hazy skies at our coastal site. The resulting polarization maps and spectra exhibit both commonalities and differences that seem unexplained by an existing polarized radiative transfer model. Comparing the measured polarization spectra with those predicted by aerosol single scattering suggests some basic verisimilitude tests for improving such models. (C) 2012 Optical Society of America

AB Many of the commonly used high strength steels have small amounts of magnetostriction. This magnetostriction can be utilized, for example to measure the torque on a rotating shaft. Previous studies on the magnetostriction in high strength steels have ignored the internal anisotropies due to previous material handling. This paper presents data taken on rods of a high strength steel that have been machined parallel, perpendicular and 45 to the rolling direction. Magnetization, magnetostriction, susceptibility, and stress-strain curves have been measured under various stresses and fields. In general, the parallel cylinders showed altered B - H, susceptibility, and magnetostriction curves compared to the other two orientations. These measurements will be incorporated into a future Vector Preisach model allowing detailed predictions of the magnetic state after stress and field changes.

AB We report measured ferromagnetic susceptibility and our unifield model of hysteresis, physically describing hysteresis from minor to saturate loops and virgin and anhysteretic susceptibilities. Normal susceptibility for reversals, Delta M/Delta H, and for the virgin curve, M/H, is the sum of anisotropic reversible and cooperative irreversible susceptibilities. Effective field is derived from Maxwell's thermodynamic and electromagnetic equations as the sum of Amperian, shape demagnetization, internal and external stress, eddy current and thermal fields. Rate dependence is modeled by time shifts and amplitude changes to our functions. We measure Faraday induction of ring and plate samples and vibrating sample magnetometer moments of a disc sample of mild steel, discussing procedures and precision. We find anhysteretic susceptibility to be our saturate susceptibility for positive magnetization, reflected in symmetry, with maximum susceptibility modified by each of the five fields.

AB We consider the inverse problem of identifying the location and shape of a finitely supported electromagnetic source function, separable with respect to space and frequency, from measurements of the electromagnetic field on a surface for many frequencies. A simple uniqueness proof and error estimate for the unknown source function are presented. From the uniqueness proof, an efficient numerical algorithm for the solution is developed. The algorithm is tested using numerically generated data.

AB Clostridium difficile causes one of the leading nosocomial infections in developed countries, and therapeutic choices are limited. Some strains of C. difficile produce phage tail-like particles upon induction of the SOS response. These particles have bactericidal activity against other C. difficile strains and can therefore be classified as bacteriocins, similar to the R-type pyocins of Pseudomonas aeruginosa. These R-type bacteriocin particles, which have been purified from different strains, each have a different C. difficile-killing spectrum, with no one bacteriocin killing all C. difficile isolates tested. We have identified the genetic locus of these "diffocins" (open reading frames 1359 to 1376) and have found them to be common among the species. The entire diffocin genetic locus of more than 20 kb was cloned and expressed in Bacillus subtilis, and this resulted in production of bactericidal particles. One of the interesting features of these particles is a very large structural protein of similar to 200 kDa, the product of gene 1374. This large protein determines the killing spectrum of the particles and is likely the receptor-binding protein. Diffocins may provide an alternate bactericidal agent to prevent or treat infections and to decolonize individuals who are asymptomatic carriers.

TI Clutter reduction using Doppler sonar in a harbor environment
SO JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA
LA English
DT Article
ID AMBIGUITY FUNCTION; SIGNALS; SUPPRESSION; CHANNEL
AB A high frequency experiment was conducted in the Woods Hole Harbor in Massachusetts to evaluate the effectiveness of Doppler sonar for discriminating targets from reverberation. Using a pulsed linear frequency modulated signal, one finds that the matched filtered outputs are filled with high-level discrete backscattered returns, referred to as clutter, which are often confused with the target echo. The high level non-target returns have an amplitude distribution that is heavy-tailed. Using a Doppler-sensitive binary-phase-shift-keying signal coded with an m-sequence, the target echo and clutter can be separated by Doppler and delay, and tracked using the Doppler spectrogram (Dopplergram). The Doppler filtered time series show a background reverberation with a Rayleigh-like amplitude distribution, with an improved signal-to-(peak) reverberation ratio compared with that without Doppler filtering. The reduced reverberation level with Doppler processing decreases the probability of false alarm (Pfa) for a given threshold level. Conversely, for a given Pfa, the higher signal-to-(peak) reverberation ratio implies a higher probability of detection. Transmission loss measurement was conducted to estimate some of the system parameters, e. g., the source level and target strength relative to the noise level. [http://dx.doi.org/10.1121/1.4756921]

AB Laboratory grade bistatic scattering measurements are conducted in order to examine the acoustic response of realistic fully buried unexploded ordnance (UXO) from above-critical angle insonification, between 2 and 40 kHz. A 127 mm diameter rocket UXO, a 155 mm diameter artillery shell, a natural rock of approximately the same size, and a cinder block are fully buried in water-saturated medium grained sand (mean grain diameter, 240 mu m) at depths of 10 cm below the water-sediment interface. A two-dimensional array of bistatic scattering measurements is generated synthetically by scanning a single hydrophone in steps of 3 cm over a 1m x 1m patch directly above the targets at a height of 20 cm above the water-sediment interface. Three-dimensional volumetric acoustic images generated from the return waveforms reveal scattering components attributed to geometric and elastic scattering, as well as multiple-scattering interactions of returns between the sediment-water interface and the buried objects. The far-field target strength of the objects is estimated through extrapolation of the angular spectrum. Agreement is found between experimental data and simulated data generated from a finite-element-based, three-dimensional time-harmonic model (2-25 kHz). Separation of the measured UXO from the clutter objects is demonstrated through exploitation of structural-acoustics-based features. [http://dx.doi.org/10.1121/1.4757098]

AB Spin manipulation in a semiconductor offers a new paradigm for device operation beyond Moore's law. Ferromagnetic metals are ideal contacts for spin injection and detection, but the intervening tunnel barrier required to accommodate the large difference in conductivity introduces defects, trapped charge and material interdiffusion, which severely compromise performance. Here, we show that single-layer graphene successfully circumvents the classic issue of conductivity mismatch between a metal and a semiconductor for electrical spin injection and detection, providing a highly uniform, chemically inert and thermally robust tunnel barrier. We demonstrate electrical generation and detection of spin accumulation in silicon above room temperature, and show that the contact resistance-area products are two to three orders of magnitude lower than those achieved with oxide tunnel barriers on silicon substrates with identical doping levels. Our results identify a new route to low resistance-area product spin-polarized contacts, a key requirement for semiconductor spintronic devices that rely on two-terminal magnetoresistance, including spin-based transistors, logic and memory.

AB Objective: Drawing on two different populations, Israeli police and Hungarian civilians, the present study assessed the ability of individuals with posttraumatic stress disorder (PTSD) to generalize previous learning to novel situations. Past neuroimaging studies have demonstrated diminished medial temporal lobe (MTL) activation and/or reduced hippocampal volume in individuals with PTSD. Our earlier computational models of cortico-hippocampal function and subsequent experimental tests of these models in MTL-impaired clinical populations argue that even mild hippocampal dysfunction may result in subtle impairments in generalization. Therefore, we predicted that individuals with PTSD would show impaired generalization. Method: We compared the performance of five groups from two countries, including 19 Israeli police with PTSD and 22 trauma-exposed police without PTSD, and 22 Hungarian civilians with PTSD, 25 trauma-exposed civilians without PTSD, and 25 individuals without PTSD unexposed to the same trauma. Participants were tested on a two-phase learning paradigm, the Acquired Equivalence Task, which measures the ability to generalize past learning to novel situations. Results: We found that both PTSD and non-PTSD participants were capable of learning the initial stimulus-outcome associations, F(4, 108) = 1.79, p = .14. However, as predicted, only individuals with PTSD showed a selective deficit in generalization of this learning to novel situations (F(4, 108) = 8.35, p < .001, Partial eta(2) = 0.26). Conclusions: Individuals with PTSD show a selective impairment in generalization of past learning similar to other clinical populations with MTL/hippocampal dysfunction. This is consistent with an emerging view of PTSD as being not only an anxiety disorder but also a learning disorder.

DE Coronal mass ejection
AB We identify 565 coronal mass ejections (CMEs) between January 2007 and December 2010 in observations from the twin STEREO/SECCHI/COR2 coronagraphs aboard the STEREO mission. Our list is in full agreement with the corresponding SOHO/LASCO CME Catalog (http://cdaw.gsfc.nasa.gov/CME_list/) for events with angular widths of 45 degrees and up. The monthly event rates behave similarly to sunspot rates showing a three- to fourfold rise between September 2009 and March 2010. We select 51 events with well-defined white-light structure and model them as three-dimensional (3D) flux ropes using a forward-modeling technique developed by Thernisien, Howard and Vourlidas (Astrophys. J. 652, 763-773, 2006). We derive their 3D properties and identify their source regions. We find that the majority of the CME flux ropes (82 %) lie within 30 degrees of the solar equator. Also, 82 % of the events are displaced from their source region, to a lower latitude, by 25 degrees or less. These findings provide strong support for the deflection of CMEs towards the solar equator reported in earlier observations, e.g. by Cremades and Bothmer (Astron. Astrophys. 422, 307-322, 2004).

AB A major, albeit serendipitous, discovery of the SOlar and Heliospheric Observatory mission was the observation by the Extreme Ultraviolet Telescope (EIT) of large-scale extreme ultraviolet (EUV) intensity fronts propagating over a significant fraction of the Sun's surface. These so-called EIT or EUV waves are associated with eruptive phenomena and have been studied intensely. However, their wave nature has been challenged by non-wave (or pseudo-wave) interpretations and the subject remains under debate. A string of recent solar missions has provided a wealth of detailed EUV observations of these waves bringing us closer to resolving the question of their nature. With this review, we gather the current state-of-the-art knowledge in the field and synthesize it into a picture of an EUV wave driven by the lateral expansion of the CME. This picture can account for both wave and pseudo-wave interpretations of the observations, thus resolving the controversy over the nature of EUV waves to a large degree but not completely. We close with a discussion on several remaining open questions in the field of EUV waves research.

AB During 2 -aEuro parts per thousand 18 January 2008 a pair of low-latitude opposite-polarity coronal holes (CHs) were observed on the Sun with two active regions (ARs) and the heliospheric plasma sheet located between them. We use the Hinode/EUV Imaging Spectrometer (EIS) to locate AR-related outflows and measure their velocities. Solar-Terrestrial Relations Observatory (STEREO) imaging is also employed, as are the Advanced Composition Explorer (ACE) in-situ observations, to assess the resulting impacts on the solar wind (SW) properties. Magnetic-field extrapolations of the two ARs confirm that AR plasma outflows observed with EIS are co-spatial with quasi-separatrix layer locations, including the separatrix of a null point. Global potential-field source-surface modeling indicates that field lines in the vicinity of the null point extend up to the source surface, enabling a part of the EIS plasma upflows access to the SW. We find that similar upflow properties are also observed within closed-field regions that do not reach the source surface. We conclude that some of plasma upflows observed with EIS remain confined along closed coronal loops, but that a fraction of the plasma may be released into the slow SW. This suggests that ARs bordering coronal holes can contribute to the slow SW. Analyzing the in-situ data, we propose that the type of slow SW present depends on whether the AR is fully or partially enclosed by an overlying streamer.

AB On 27 June 2009 the Wind and Advanced Composition Explorer (ACE) spacecraft near Earth detected a magnetic cloud (MC). The MC can be traced back to a slow coronal mass ejection (CME) launched from the Sun on 22 June 2009 but this connection relies entirely on heliospheric imaging of the Sun-Earth line from the two STEREO spacecraft, illustrating the value of such imaging. The STEREO and SOHO/LASCO views of this event collectively suggest strongly that the CME has the shape of a magnetic flux rope. The arrival times of two density peaks at ACE are consistent with the expected arrival times of the front and back of the flux rope observed in the images, and the velocity of the CME seen by ACE is also consistent with the STEREO measurements. However, the complex nature of the MC signature of this event complicates attempts to compare the flux rope orientations inferred from the imaging and in situ data. Various analyses of the in situ data, performed using both force-free and Grad-Shafranov approaches to MC modeling, yield a wide range of flux rope orientations depending on the type of analysis and on the exact time interval used. The best reproduction of the image-inferred orientation occurs when the first third of the MC time interval is ignored.

DT Article
DE Fibre Bragg grating; structural health monitoring; modal analysis;

structural irregularity and damage evaluation routine
AB This article reports on the development of a technique for broad area detection of structural irregularities in composites using an integrated fibre optic sensing network. The technique is founded on a broadband vibration-based methodology known as the structural irregularity and damage evaluation routine that uses features in complex curvature operating shapes to locate damage and other areas with structural stiffness variations. The original structural irregularity and damage evaluation routine methodology relied on impact excitation at a series of grid points on the structure with the response recorded using a small number of reference accelerometers to determine the operating curvature shapes. This methodology has been modified to allow for single-point or environmental excitation with measurement of the curvature shapes provided by a spatially dense network of fibre Bragg grating strain sensors' surface mounted on the structure. This modified approach is known as the inverse structural irregularity and damage evaluation routine and has been experimentally validated on an impact-damaged composite panel. The technique was then applied to a full size composite structure (ship's rudder) containing structural features, where it was shown to successfully locate impact damage.

AB There has been significant research in the study of in-plane charge-carrier transport in graphene in order to understand and exploit its unique electrical properties; however, the vertical graphene-semiconductor system also presents opportunities for unique devices. In this letter, we investigate the epitaxial graphene/p-type 4H-SiC system to better understand this vertical heterojunction. The I-V behavior does not demonstrate thermionic emission properties that are indicative of a Schottky barrier but rather demonstrates characteristics of a semiconductor heterojunction. This is confirmed by the fitting of the temperature-dependent I-V curves to classical heterojunction equations and the observation of band-edge electroluminescence in SiC.

These modifications include changes to innovation covariance portioning, covariance binning, and analysis increment calculation. A validation of the modified OI technique is presented, comparing the retrievals with the original technique in each case.

AB Aims To develop test methods and evaluate the survival of Bacillus anthracis ?Sterne and Bacillus thuringiensis Al Hakam spores after exposure to hot, humid air. Methods and Results Spores (>7 logs) of both strains were dried on six different test materials. Response surface methodology was employed to identify the limits of spore survival at optimal test combinations of temperature (60, 68, 77 degrees C), relative humidity (60, 75, 90%) and time (1, 4, 7days). No spores survived the harshest test run (77 degrees C, 90% r.h., 7days), while>6.5 logs of spores survived the mildest test run (60 degrees C, 60% r.h., 1day). Spores of both strains inoculated on nylon webbing and polypropylene had greater survival rates at 68 degrees C, 75% r.h., 4days than spores on other materials. Electron microscopy showed no obvious physical damage to spores using hot, humid air, which contrasted with pH-adjusted bleach decontamination. Conclusions Test methods were developed to show that hot, humid air effectively inactivates B.anthracis Delta Sterne and B.thuringiensis Al Hakam spores with similar kinetics. Significance and Impact of the Study Hot, humid air is a potential alternative to conventional chemical decontamination.

AB Progressive vaccinia (PV) is a rare but potentially lethal complication that develops in smallpox vaccine recipients with severely impaired cellular immunity. We describe a patient with PV who required treatment with vaccinia immune globulin and who received 2 investigational agents, ST-246 and CMX001. We describe the various molecular, pharmacokinetic, and immunologic studies that provided guidance to escalate and then successfully discontinue therapy. Despite development of resistance to ST-246 during treatment, the patient had resolution of PV. This case demonstrates the need for continued development of novel anti-orthopoxvirus pharmaceuticals and the importance of both intensive and timely clinical and laboratory support in management of PV.

AB Purpose: The purpose of this descriptive correlational study was to describe the coping behaviors used by Army wives during deployment separation, the perceived effectiveness of the coping behaviors used, and the correlation between the two variables. Data sources: A secondary analysis was conducted to examine coping use and perceived effectiveness, measured by the Jalowiec Coping Scale (JCS), in a sample of 102 Army wives surveyed during deployment separation. Conclusions: The most used coping subscales from the JCS were the optimistic and supportant and the most effective were the supportant and confrontive. The strongest correlations between coping use and effectiveness were found in the supportant subscale, which measures use of support systems (r= 0.77, p < .00), and the confrontive subscale, which includes behaviors of constructive problem solving (r= 0.62, p < .00). The use and effectiveness of individual behaviors are also identified. Implications for practice: Identifying effective and ineffective coping behaviors of spouses of deployed troops can potentially reduce stress and improve well-being. Primary care providers should encourage military spouses to engage in optimistic thinking, seek out spiritual support, talk to others in a similar situation, and participate in physical activity.

AB Quantifying air-sea exchanges of enthalpy and momentum is important for understanding and skillfully predicting tropical cyclone intensity, but the magnitude of the corresponding wind speed-dependent bulk exchange coefficients is largely unknown at major hurricane wind speeds greater than 50 m s(-1). Since direct turbulent flux measurements in these conditions are extremely difficult, the momentum and enthalpy fluxes were deduced via absolute angular momentum and total energy budgets. An error analysis of the methodology was performed to quantify and mitigate potentially significant uncertainties resulting from unresolved budget terms and observational errors. An analysis of six missions from the 2003 Coupled Boundary Layers Air-Sea Transfer (CBLAST) field program in major hurricanes Fabian and Isabel was conducted using a new variational technique. The analysis indicates a near-surface mean drag coefficient C-D of 2.4 X 10(-3) with a 46% standard deviation and a mean enthalpy coefficient C-K of 1.0 x 10(-3) with a 40% standard deviation for wind speeds between 52 and 72 m s-1. These are the first known estimates of C-K and the ratio of enthalpy to drag coefficient C-K/C-D in major hurricanes. The results suggest that there is no significant change in the magnitude of the bulk exchange coefficients estimated at minimal hurricane wind speeds, and that the ratio C-K/C-D does not significantly increase for wind speeds greater than 50 m s(-1).

AB In this article, we review our efforts to continuously tune mechanical and thermal properties in multilayer chemically modified graphene (CMG) films. An alteration of the graphene lattice by functional groups, by defects created during reduction, or by defect re-crystallization is used to control CMG mechanical and thermal properties. We attribute a notable increase in Young's modulus and film strength to an emerging network of sp(2)-sp(3) crosslinks established between graphene layers. Control over the film stress and strength enabled us to dramatically improve the performance of radio frequency CMG resonators by fine tuning the fabrication process. Published by Elsevier Ltd.

Introduction: Effective hypoxia-related mishap prevention relies upon aircrew rapid recognition of hypoxia symptoms. The objectives of this experiment were twofold: to compare the effectiveness of a forehead-mounted reflectance oximeter and finger-mounted pulse oximeter for application in a hypoxia early warning detection system, and to determine whether the forehead-mounted sensor could be placed within an aviation helmet. Methods: Subjects donned an aviation flight mask and were instrumented with a forehead reflectance oximeter, a finger pulse oximeter, a blood pressure cuff, and a skin temperature sensor. Following instrumentation, subjects breathed ambient air for 10 min through the Reduced Oxygen Breathing Device (ROBD) to allow for acclimation. The baseline period was followed by one of two counterbalanced ascent profiles used to model rapid exposures to altitude. Data were collected at 1 Hz from both sensors for the duration of the protocol. Results: Analyses indicated an exceptionally strong agreement between the forehead and finger sensors at all ranges of desaturation. The sensitivity data revealed that the forehead sensor was significantly faster when responding to rapid changes in SpO2 than the finger. The sensor was successfully integrated inside the helmet; however, once donned by the subject, there was considerable artifact due to pressure fluctuations. Discussion: While these data may seem to suggest that the forehead sensor is accurate and sensitive to altitude induced changes in SpO2, major drawbacks exist for the technology utilized in the current study. Significant improvements aimed at diminishing noise, curbing motion artifact, and improving reliability are required to reduce errant measurements.

AB Spatial arrangement of information can have large effects on problem solving. Although such effects have been observed in various domains (e.g., instruction and interface designs), little is known about the cognitive processing mechanisms underlying these effects, nor its applicability to complex visual problem solving. In three experiments, we showed that the impact of spatial arrangement of information on problem solving time can be surprisingly large for complex real world tasks. It was also found that the effect can be caused by large increases in slow, external information searches (Experiment I), that the spatial arrangement itself is the critical factor and the effect is domain-general (Experiment 2a), and that the underlying mechanism can involve micro-strategy selection for information encoding in a response to differing information access cost (Experiment 2b). Overall, these studies show a large slowdown effect (i.e., approximately 30%) that stacking information produces over spatially distributed information, and multiple paths by which this effect can be produced.

AB In this study, we evaluated a recently developed multilocus variable-number tandem-repeat (VNTR) analysis (MLVA) method for the molecular typing of Mycoplasma pneumoniae. The method is based on GeneScan analysis of five VNTR loci throughout the genome which define a specific genotype based on the number of tandem repeats within each locus. A retrospective analysis of 154 M. pneumoniae clinical isolates collected over the last 50 years and a limited (n = 4) number of M. pneumoniae-positive primary specimens acquired by the CDC was performed using MLVA. Eighteen distinct VNTR types were identified, including two previously unidentified VNTR types. Isolates from several M. pneumoniae community outbreaks within the United States were also analyzed to examine clonality of a specific MLVA type. Observed in vitro variability of the Mpn1 VNTR locus prompted further analysis, which showed multiple insertions or deletions of tandem repeats within this locus for a number of specimens and isolates. To our knowledge, this is the first report showing variation within the Mpn1 locus, thus affecting precise and reliable classification using the current MLVA typing system. The superior discriminatory capability of MLVA provides a powerful tool for greater resolution of M. pneumoniae strains and could be useful during outbreaks and epidemiological investigations.

AB Aerospace alloys, often aluminums, are frequently exposed to corrosive environments resulting from naval service. These environments may produce significant changes in crack growth characteristics in these materials. An experiment was designed to characterize the effects of environment on crack growth thresholds and fracture characteristics for existing cracks in aluminum 7050-T7451 plate material. This data will be comparatively analyzed against aluminum 7075-T7631, an alloy with known susceptibility to corrosion, in order to determine a relative susceptibility of 7050-T7451, generally considered a superior aluminum alloy in terms of strength and corrosion resistance. The resulting data and subsequent analysis can in turn be used in more accurate determination of aircraft component service life in common corrosive environments experienced by aircraft in naval service.

AB White matter is composed primarily of myelinated axons which form fibrous, organized structures and can act as waveguides for the anisotropic propagation of sound. The evaluation of their elastic properties requires both knowledge of the orientation of these waveguides in space, as well as knowledge of the waves propagating along and through them. Here, we present waveguide elastography for the evaluation of the elastic properties of white matter tracts in the human brain, in vivo, using a fusion of diffusion tensor imaging, magnetic resonance elastography, spatial-spectral filtering, a Helmholtz decomposition, and anisotropic inversions, and apply this method to evaluate the material parameters of the corticospinal tracts of five healthy human volunteers. We begin with an Orthotropic inversion model and demonstrate that redundancies in the solution for the nine elastic coefficients indicate that the corticospinal tracts can be approximated by a Hexagonal model (transverse isotropy) comprised of five elastic coefficients representative of a medium with fibers aligned parallel to a central axis, and provides longitudinal and transverse wave velocities on the order of 5.7 m/s and 2.1 m/s, respectively. This method is intended as a new modality to assess white matter structure and health by means of the evaluation of the anisotropic elasticity tensor of nerve fibers. Magn Reson Med, 2012.

AB We formulate a rational choice model of popular behavior during an insurgency. An individual in the population either supports the insurgents or the government depending upon his attitude and the actions taken by each side. We focus on the effect of insurgency actions: benefits, impositions, and coercion. While benefits and impositions are applied uniformly throughout, the insurgents intend to only coerce those actively providing information to the government. However, due to the "fog of war", which may lead to limited situational awareness, the insurgents may mistakenly coerce their own supporters and potentially drive them to aid the government. We examine how popular behavior varies under different situational awareness scenarios. When the insurgents have little situational awareness, they should take few coercive actions. This implies that the government will be able to foster intelligence sources within the population. If the insurgents have perfect situational awareness, tipping points may occur that result in a significant reduction in active support for the government. In this case the government should take actions to decrease the coercing effectiveness of the insurgents and increase incentives to the population so they continue to provide information.

AB To assess the regenerative properties and potential therapeutic value of adipose-derived stem cells (ASCs) in the bottlenose dolphin, there is a need to determine whether an adequate adipose depot exists, in addition to the development of a standardized technique for minimally invasive adipose collection. In this study, an ultrasound-guided liposuction technique for adipose collection was assessed for its safety and efficacy. The ultrasound was utilized to identify and measure the postnuchal adipose depot and aid in the guidance of the liposuction cannula during aspiration. Liposuction procedures from 6 dolphins yielded 0.9-12.7 g of adipose. All samples yielded sufficient nucleated cells to initiate primary cell cultures, and at passage 2, were successfully differentiated into adipogenic, chondrogenic, neurogenic, and osteogenic cell lineages. The cultured dolphin cells expressed known stem-cell-associated CD markers, CD44 and CD90. Ultrasound-guided liposuction proved to be a safe and minimally invasive procedure that resulted in the successful isolation of ASCs in bottlenose dolphins. This is the first article that conclusively establishes the presence of stem cells in the dolphin.

AB Morphodynamic models of coastal evolution require relatively simple parameterizations of sediment transport for application over larger scales. Calantoni and Thaxton (2008) [6] presented a transport parameterization for bimodal distributions of coarse quartz grains derived from detailed boundary layer simulations for sheet flow and near sheet flow conditions. The simulation results, valid over a range of wave forcing conditions and large-to small-grain diameter ratios, were successfully parameterized with a simple power law that allows for the prediction of the transport rates of each size fraction. Here, we have applied the simple power law to a two-dimensional cellular automaton to simulate sheet flow transport. Model results are validated with experiments performed in the small oscillating flow tunnel (S-OFT) at the Naval Research Laboratory at Stennis Space Center, MS, in which sheet flow transport was generated with a bed composed of a bimodal distribution of non-cohesive grains. The work presented suggests that, under the conditions specified, algorithms that incorporate the power law may correctly reproduce laboratory bed surface measurements of bimodal sheet flow transport while inherently incorporating vertical mixing by size.

AB We introduce a novel task that arises in underwater search and inspection. In this task, an underwater vehicle must re-acquire and identify clusters of discrete objects. The challenge is to generate an efficient path for the vehicle given a probabilistic description of potential target locations. We propose an algorithm that generates an efficient path and show that the algorithm is superior to standard approaches. Hardware implementation and field experiments using this algorithm are presented using a REMUS-100 autonomous underwater vehicle on simulated targets. The use of this algorithm is compared to two baseline methods of performing a multiple-aspect coverage mission. The field experiments imply that the proposed algorithm is superior in speed to the baseline methods. Published by Elsevier Ltd.

AB The primary mission of the US Navy (USN) is to maintain superior naval forces capable of winning wars, deterring aggression, and maintaining freedom of the seas. However, a major core capability of the present-day USN includes the ability to effectively and rapidly provide humanitarian assistance and disaster response whenever the need arises. Occurring annually since 2006, Pacific Partnership is an ongoing USN operation that aims to strengthen regional alliances and improve delivery of humanitarian assistance and disaster relief. A major focus of Pacific Partnership 2010 was the delivery of medical care to underserved communities in the region. A significant portion of the medical mission was specifically directed toward the treatment of patients with cleft lip and palate. As the main operational platform, the USN Ship Mercy provided an unparalleled environment in which to provide state-of-the-art multidisciplinary treatment to patients with cleft lip and palate. With the cooperation of host nations and locally active non-governmental organizations, a sustainable model for providing treatment for cleft lip and palate can be developed.

DE resistance; powering; stern bulb; stern flap; wave-making
AB Unlike the bow bulb, the stern end bulb (SEB) has been used on just a few ships to improve performance. In one of these rare, full-scale applications, a maximum resistance reduction in the 5% to 7% range is claimed. A few applications of SEBs are shown along with some model test data for a Naval Auxiliary ship. The rationale for SEB is discussed along with the hydrodynamic mechanism associated with a SEB. In addition to wave-making reduction, the SEB can reduce eddy-making and possibly improve course-keeping. The results of several fluid flow computations with initial SEB designs are shown for two ship classes: the T-AKE LEWIS and CLARK dry cargo ship and the DDG 51 ARLEIGH BURKE destroyer. The calculations use the Ship Wave Inviscid Flow Theory potential flow computer code and the FreeRans viscous flow free surface computer code. Several SEBs were designed and investigated analytically for the T-AKE class ships, and the best of these is predicted to reduce resistance by 4.5% at 20 knots. In addition, several initial SEB/Stern Flap configurations were designed for the DDG 51 Class Flight IIa destroyers and five configurations, some with just an SEB added to the hull and others with a combined SEB-Stern Flap configuration were model-tested. The examination of these initial efforts led to the design of several new-style combined SEB-Stern flap configurations, the best of which is predicted to save at least 745 Bbls of fuel per ship per year.

AB Stern flaps have now been at sea for more than two decades on a variety of U.S. Navy (USN) and U.S. Coast Guard classes, including destroyers, cruisers, frigates, cutters, and patrol craft. Application of flaps to large-deck amphibious-type ships is a fairly recent extension of the technology. Ship performance improvements such as delivered power reduction and fuel savings, and maximum speed increases, have been proven during at-sea trials and are well documented (Cusanelli 2002). USN amphibious ships contain well decks, which are accessed through large folding stern gates. When open, the gates are supported by sizable structures, which are partially submerged and affixed to the transom. A new concept, the hydrodynamic and supportive structure for gated ship sterns, i.e., the amphibious stern flap, was developed and patented by the author (Cusanelli 2004a). This design combines a stern flap's hydrodynamic performance surface with the stern gate support structure. The Naval Surface Warfare Center, Carderock Division, has now designed and implemented this new type of integrated stern flap and gate support structure on several USN amphibious ship classes. USN ship design and research and development (R&D) programs have resulted in amphibious stern flaps being implemented as new construction items on two new Navy amphibious ship classes and one new subclass. The Fleet Readiness R&D Program has funded amphibious stern flap design, retrofit installations, and evaluation trials on two existing amphibious ships. Each amphibious stern flap design spiral, model-test series, optimization, full-scale implementation as well as performance benefits and fuel savings are discussed.

AB We evaluated repeated exposures of mice to a trained aggressor mouse as a model (adapted from "social stress" models of traumatic stress) for aspects of post-traumatic stress disorder (PTSD). Using a "cage-within-cage resident-intruder" protocol, subject C57BL/6J mice were exposed to aggressors for 6 h daily for 5 or 10 days. At one to three random times during each 6-h session, subjects were exposed directly to aggressor for 1 min or 10 bites, whichever came first. Behavioral, physiological, and histological changes associated with aggressor-exposure were assessed for up to 6 weeks. During aggressor exposure, subjects displayed less territorial behavior, gained weight, and increased body temperature. One day after the last aggressor exposure, inflammatory cardiac histopathologies were prevalent; after 10 days, only mild myocardial degeneration with fibrosis or fibroplasias was evident, while controls showed almost no cardiac abnormalities at any time. After 4 weeks, the medial prefrontal cortex of control mice showed increased dendritic spine density, but aggressor-exposed mice showed no increase. Behaviors affected by aggressor exposure were evaluated in a partition test wherein the subject mouse is separated from the aggressor by a fenestrated partition that permits sensory cues to pass but prevents direct physical interaction. For up to 4-6 weeks after the last aggressor exposure, subjects showed prolonged grooming, freezing, retarded locomotion and no tail rattling. PTSD and its co-morbidities are often consequent to repeated aggravated "social" assaults (e.g., combat) and manifest socially over time, suggesting the relevance of this repeated aggressor-exposure model to clinical aspects of PTSD.

AB The ability of an antimicrobial, cationic polyethylenimine (PEI+) to induce the three known extracytoplasmic stress responses of Escherichia coli was quantified. Exposure of E. coli to PEI+ in solution revealed specific, concentration-dependent induction of the Cpx extracytoplasmic cellular stress response, similar to 2.0-2.5-fold at 320 mu g/mL after 1.5 h without significant induction of the sigma(E) or Bae stress responses. In comparison, exposure of E. coli to a non-antimicrobial polymer, poly(ethylene oxide) (PEO), resulted in no induction of the three stress responses. The antimicrobial small molecule vanillin, a known membrane pore-forming compound, was observed to cause specific, concentration-dependent induction of the sigma(E) stress response, similar to 6-fold at 640 mu g/mL after 1.5 h, without significant induction of the Cpx or Bae stress responses. The different stress response induction profiles of PEI+ and vanillin suggest that although both are antimicrobial compounds, they interact with the bacterial membrane and extracytoplasmic area by unique mechanisms.

AB This paper presents the Attitude, Skills, Knowledge, and Experience-Knowledge Value Added (ASKE-KVA) methodology developed from the designed Individual Technical Competence (ITC) of a value chain to assess changes in the Human Capital of a company. It is based on the Knowledge Value Added (KVA) method, which proposes the use of a proxy variable for measuring the flow of knowledge used in a key Process. This variable creates a relationship between the company's financial results and the resources used in each of the business processes. The KVA method uses an indicator that measures the result of knowledge per unit (K mu), which transforms costs and investments in the same unit. The ASKE-KVA methodology expands the previous concept, using fuzzy logic to measure the flow of knowledge associated with each ITC and, therefore, making it possible to obtain the return on investment of a particular business process.

AB The United States used a combination of economic, political, and military means to effect change in Iraq. Most notably, the United States used a buildup of security forces, the "surge", as an intervention to stabilize Iraq. This article uses structural change tests to determine the effect of the intervention on security and economic metrics of success. There appears to be compelling evidence that several events may have had a direct influence on security variables with the surge being one of the events. There is little to suggest that the surge was the primary intervention that enhanced economic development and political order. Published by Elsevier B.V.

AB NUCu-140 is a copper-precipitation-strengthened steel that exhibits excellent mechanical properties with a relatively simple chemical composition and processing schedule. As a result, NUCu-140 is a candidate material for use in many naval and structural applications. Before NUCu-140 can be implemented as a replacement for currently used materials, the weldability of this material must be determined under a wide range of welding conditions. This research represents an initial step toward understanding the microstructural and mechanical property evolution that occurs during fusion welding of NUCu-140. Microhardness traverses and tensile testing using digital image correlation show local softening in the heat-affected zone (HAZ). Microstructural characterization using light optical microscopy (LOM) revealed very few differences in the softened regions compared with the base metal. Local-electrode atom-probe (LEAP) tomography demonstrates that local softening occurs as a result of dissolution of the Cu-rich precipitates. MatCalc kinetic simulations (Vienna, Austria) were combined with welding heat-flow calculations to model the precipitate evolution within the HAZ. Reasonably good agreement was obtained between the measured and calculated precipitate radii, number density, and volume fraction of the Cu-rich precipitates in the weld. These results were used with a precipitate-strengthening model to understand strength variations within the HAZ.

AB This work presents I-131 (t(1/2) = 8.04 d) concentrations in sewage effluent from the Stony Brook Water Pollution Control Plant (WPCP), a small plant serving a regional thyroid cancer treatment facility in Stony Brook, NY, USA. The concentrations detected in sewage effluent ranged from 1.8 +/- 0.3 to 227 +/- 2 Bq L-1. The primary source of I-131 is excreta from thyroid cancer inpatients treated at the Stony Brook University Medical Center. Based on several time series measurements following known inpatient treatments, the mean sewage half-life (T-s) of iodine is 3 d in this plant. The T-s, analogous to a radioactive half-life, describes the time it takes for half of a wastewater component to be removed from a WPCP. Flow recycling, or activated sludge, used to maintain bacterial populations necessary for sewage treatment causes iodine to remain in this plant far longer than its hydraulic retention time. The experimental results suggest that most I-131 entering the Stony Brook WPCP leaves in sewage effluent, not in sewage sludge. Patient treatments can result in continuous discharges of I-131 to surface waters where it can be used as a tracer of sewage-derived material and to understand the behavior of I-131 in aquatic environments.

TI Structural evolution of carbide-derived carbons upon vacuum annealing
SO CARBON
LA English
DT Article
ID GRAPHITE
AB Microstructure and surface moieties of porous carbons play a significant role in affecting their performance in a variety of applications. While it is well known that high-temperature treatments of porous carbons can influence the microstructure, no systematic studies have been done on carbide-derived carbons. We show that vacuum annealing increases the pore volume and specific surface area of titanium carbide-derived carbon with no significant change in the pore size up to 1500 degrees C. This treatment produces porous carbons with subnanometer porosity and a specific surface area up to 2000 m(2)/g, while treating the samples at temperatures above 1600 degrees C increases the pore size above 1 nm because of graphitization and collapse of the micropore structure. The results demonstrate that vacuum treatment can be used to further tune the pore structure and potentially the surface functionality of carbide-derived carbons for supercapacitor electrodes, gas chromatography, sorption, sensing and other applications. Vacuum annealing of carbide-derived carbon is therefore a suitable alternative to conventional microstructure modification methods, such as gas or liquid phase activation, which are subject to substantial sample loss and result in additional surface functionalization.

AB Exposure to intense sounds often leads to loss of hearing of environmental sounds and hearing of a monotonous tonal sound not actually present, a condition known as tinnitus. Chronic physiological effects of exposure to intense tones have been reported for animals and should be accompanied by chemical changes present at long times after the intense sound exposure. By using a microdissection mapping procedure combined with high-performance liquid chromatography (HPLC), we have measured concentrations of nine amino acids, including those used as neurotransmitters, in the cochlear nucleus, inferior colliculus, medial geniculate, and auditory cortex of hamsters 5 months after exposure to an intense tone, compared with control hamsters of the same age. No very large differences in amino acid concentrations were found between exposed and control hamsters. However, increases of glutamate and ?-aminobutyrate (GABA) in some parts of the inferior colliculus of exposed hamsters were statistically significant. The most consistent differences between exposed and control hamsters were higher aspartate and lower taurine concentrations in virtually all regions of exposed hamsters, which reached statistical significance in many cases. Although these amino acids are not considered likely neurotransmitters, they indirectly have roles in excitatory and inhibitory neurotransmission, respectively. Thus, there is evidence for small, widespread, long-term increases in excitatory transmission and decreases in inhibitory transmission after a level of acoustic trauma previously shown to produce hearing loss and tinnitus.

AB We consider the problem of finding a sparse multiple of a polynomial. Given faF[x] of degree d over a field F, and a desired sparsity t, our goal is to determine if there exists a multiple haF[x] of f such that h has at most t non-zero terms, and if so, to find such an h. When F=a"e and t is constant, we give an algorithm which requires polynomial-time in d and the size of coefficients in h. When F is a finite field, we show that the problem is at least as hard as determining the multiplicative order of elements in an extension field of F (a problem thought to have complexity similar to that of factoring integers), and this lower bound is tight when t=2.

AB We developed a model for inexpensive Direct Numerical Simulations of particle-laden flow by fully resolving the hydrodynamics at all times except when the gap between colliding particles becomes comparable to the grid step. The resolved hydrodynamics were obtained with a previously developed pressure boundary integral method for direct fluid-particle simulations on Cartesian grids. The unresolved part of the lubrication pressure/shear force in the subgrid gap was predicted using theoretical Stokes flow models. Singular lubrication forces were avoided by postulating that contact begins when the gap distance between the particles becomes equal to the size of micro-asperities. The mechanical contact between particles is dynamically resolved and particle interactions are both inelastic and frictional. The proposed numerical model was validated through resolution tests and comparison with experimental data for immersed binary collisions. Published by Elsevier Ltd.

AB Social science is broadly defined as the analysis of human behavior whether it be at an individual or a group level. In this work, we explore the analysis of human behavior encoded as a trail of their events over time and space, which we refer to as behavioral event data. We show that such data offers challenges to data mining algorithm designers as the data to analyze is naturally multi-way, involves complex patterns that form/reform over time, and has complex interactions between groups in the population. Though the data naturally lends itself to be represented as graphs and tensors we show how existing techniques are limited in their usefulness and outline our own algorithms to overcome these challenges. In this paper, using the adversarial event behavior of blue and red forces, we show three core problems and solutions in event behavior analysis: (1) Decomposing behavior to identify areas of intense activity, (2) Predicting what groups of events are likely to occur, and (3) Analysis to identify interacting behavior given a known template.

FRAMEWORK
AB An algorithm for computing wavefronts, based on the high frequency approximation to the wave equation, is presented. This technique applies the level set method to underwater acoustic wavefront propagation in the time domain. The level set method allows for computation of the acoustic phase function using established numerical techniques to solve a first order transport equation to a desired order of accuracy. Traditional methods for solving the eikonal equation directly on a fixed grid limit one to only the first arrivals, so these approaches are not useful when multi-path propagation is present. Applying the level set model to the problem allows for the time domain computation of the phase function on a fixed grid, without having to restrict to first arrival times. The implementation presented has no restrictions on range dependence or direction of travel, and offers improved efficiency over solving the full wave equation which under the high frequency assumption requires a large number of grid points to resolve the highly oscillatory solutions. Boundary conditions are discussed, and an approach is suggested for producing good results in the presence of boundary reflections. An efficient method to compute the amplitude from the level set method solutions is also presented. Comparisons to analytical solutions are presented where available, and numerical results are validated by comparing results with exact solutions where available, a full wave equation solver, and with wavefronts extracted from ray tracing software.

AB The application of luminescent semiconductor quantum dots (QDs) within a wide range of biological imaging and sensing formats is now approaching its 15th year. The unique photophysical properties of these nanomaterials have long been envisioned as having the potential to revolutionize biosensing within cellular studies that rely on fluorescence. However, it is only now that these materials are making the transition towards accomplishing this goal. With the idea of understanding how to actively incorporate QDs into different types of cellular biosensing, we review the progress in many of the areas relevant to achieving this goal. This includes the synthesis of the QDs themselves, with an emphasis on minimizing potential toxicity, along with the general methods for making these nanocrystalline structures stable in aqueous media. We next survey some methods for conjugating QDs to biomolecules to allow them to participate in active biosensing. Lastly, we extensively review many of the applications where QDs have been demonstrated in an active role in cellular biosensing. These formats cover a wide range of possibilities including where the QDs have contributed to: monitoring the cell's interaction with its extracellular environment; elucidating the complex molecular interplay that characterizes the plasma membrane; understanding how cells continuously endocytose and exocytose materials across the cellular membrane; visualizing organelle trafficking; and, perhaps most importantly, monitoring the intracellular presence of target molecules such as nucleic acids, nutrients, cofactors, and ions or, alternatively, intracellular responses to external changes in the environment. We illustrate these processes with examples from the recent literature and focus on what QDs can uniquely contribute along with discussing the benefits and liabilities of each sensing strategy. A perspective on where this field is expected to develop in both the near and long-term is also provided. Published by Elsevier B.V.

AB We report measurements of charmed-hadron (D-0, D*) production cross sections at midrapidity in p + p collisions at a center-of-mass energy of 200 GeV by the STAR experiment. Charmed hadrons were reconstructed via the hadronic decays D-0 -> K- pi(+), D*(+) -> D-0 pi(+) -> K-pi(+)pi(+) and their charge conjugates, covering the p(T) range of 0.6-2.0 and 2.0-6.0 GeV/c for D-0 and D*(+), respectively. From this analysis, the charm-pair production cross section at midrapidity is d sigma/dy vertical bar(c (c) over bar)(y-0) = 170+/-45(stat)(-59)(+38()sys) mu b. The extracted charm-pair cross section is compared to perturbative QCD calculations. The transverse momentum differential cross section is found to be consistent with the upper bound of a fixed-order next-to-leading logarithm calculation.

AB This review examines vestibular compensation and vestibular rehabilitation from a unified translational research perspective. Laboratory studies illustrate neurobiological principles of vestibular compensation at the molecular, cellular and systems levels in animal models that inform vestibular rehabilitation practice. However, basic research has been hampered by an emphasis on 'naturalistic' recovery, with time after insult and drug interventions as primary dependent variables. The vestibular rehabilitation literature, on the other hand, provides information on how the degree of compensation can be shaped by specific activity regimens. The milestones of the early spontaneous static compensation mark the re-establishment of static gaze stability, which provides a common coordinate frame for the brain to interpret residual vestibular information in the context of visual, somatosensory and visceral signals that convey gravitoinertial information. Stabilization of the head orientation and the eye orientation (suppression of spontaneous nystagmus) appear to be necessary by not sufficient conditions for successful rehabilitation, and define a baseline for initiating retraining. The lessons from vestibular rehabilitation in animal models offer the possibility of shaping the recovery trajectory to identify molecular and genetic factors that can improve vestibular compensation.

AB The fast oxygen-conducting cubic phase of zirconia is commonly stabilized by the substitution of group III cations such as yttrium and scandium, which creates vacancies in the oxygen sublattice. While scandia stabilized zirconia can achieve higher conductivity in freshly prepared specimens, it has previously been shown that yttria provides better stabilization characteristics than scandia, especially after extended operation at high temperatures. Density functional simulations of yttria and scandia zirconia show that oxygen ions neighboring vacancies can move into interstitial locations, effectively causing partial occupancy of neighboring anion sites, particularly in specimens containing scandia. Such partial occupancies can stabilize the substance in an ordered arrangement, causing age-related degradation over time, and can explain the diffuse scattering seen in X-ray diffraction studies of aged electrolytes. This tendency is reduced by increasing the yttria content of the mixture. Comparisons against rigid ion models show that the bonding is primarily ionic, but when cations become lower coordinated, the strength of the ionic bond increases, which can pull oxygen ions away from their ideal cubic lattice sites into interstitial locations that are shown to be stable at low temperature, a phenomenon which is more common in proximity to scandium ions than near yttrium ions.

AB Global comparisons of barotropic and internal tides generated in an eddy-resolving ocean circulation model are made with tidal estimates obtained from altimetric sea surface heights and an altimetry-constrained tide model. As far as we know, our Hybrid Coordinate Ocean Model (HYCOM) simulations shown here and in an earlier paper are the only published high-resolution global simulations to contain barotropic tides, internal tides, the general circulation, and mesoscale eddies concurrently. Comparing the model barotropic tide with a global data-assimilative shallow water tide model shows that the global tidal elevation differences are approximately evenly split between discrepancies in tidal amplitude and phase. Both the model and observations show strong generation of internal tides at a limited number of "hot spot" regions with propagation of beams of energy for thousands of kilometers away from the sources. The model internal tidal amplitudes compare well with observations near these energetic tidal regions. Averaged over these regions, the model and observation internal tide amplitude estimates agree to approximately 15% for the four largest semidiurnal constituents and 23% for the four largest diurnal constituents. Away from the hot spots, the comparison between the model and altimetric amplitude is not as good due, in part, to two problems, errors in the model barotropic tides and overestimation of the altimetric tides in regions of strong mesoscale eddy activity. Examining the general energy distribution of the simulated internal tide is an important first step in the evaluation of internal tides in HYCOM.

AB Background: We recently developed two Bayesian networks, referred to as the Bayesian-Estimated Tools for Survival (BETS) models, capable of estimating the likelihood of survival at 3 and 12 months following surgery for patients with operable skeletal metastases (BETS-3 and BETS-12, respectively). In this study, we attempted to externally validate the BETS-3 and BETS-12 models using an independent, international dataset.
Methods: Data were collected from the Scandinavian Skeletal Metastasis Registry for patients with extremity skeletal metastases surgically treated at eight major Scandinavian referral centers between 1999 and 2009. These data were applied to the BETS-3 and BETS-12 models, which generated a probability of survival at 3 and 12 months for each patient. Model robustness was assessed using the area under the receiver-operating characteristic curve (AUC). An analysis of incorrect estimations was also performed.
Results: Our dataset contained 815 records with adequate follow-up information to establish survival at 12 months. All records were missing data including the surgeon's estimate of survival, which was previously shown to be a first-degree associate of survival in both models. The AUCs for the BETS-3 and BETS-12 models were 0.79 and 0.76, respectively. Incorrect estimations by both models were more commonly optimistic than pessimistic.
Conclusions: The BETS-3 and BETS-12 models were successfully validated using an independent dataset containing missing data. These models are the first validated tools for accurately estimating postoperative survival in patients with operable skeletal metastases of the extremities and can provide the surgeon with valuable information to support clinical decisions in this patient population.

AB We develop a theory describing the operation of an opto-mechanical oscillator as a phonon laser using a set of coupled equations that is analogous to the standard set of laser rate equations. We show that laser-like parameters that characterize gain, stored energy, threshold, efficiency, oscillation frequency linewidth, and saturation power can be introduced for an opto-mechanical oscillator driven by photo-thermal or radiation pressure forces. We then apply the theoretical model to the experimental results for photo-thermally driven oscillations in a Si waveguide opto-mechanical resonator and show good agreement between the theory and experiments. We also consider the microscopic mechanism that transforms the energy of incoherent thermal phonons into coherent oscillations of a single phonon mode and show remarkable parallels with the three-wave parametric interactions in optics and also with opto-electronic oscillators used in microwave photonics.

ID BAND-GAP
AB A single phase InN epitaxial film is grown on a bulk In2O3(111) wafer by plasma-assisted molecular beam epitaxy. The InN/In2O3 orientation relationship is found to be (0001) parallel to (111) and [1 (1) over bar 00] parallel to [11 (2) over bar]. High quality of the layer is confirmed by the small widths of the x-ray rocking curves, the sharp interfaces revealed by transmission electron microscopy, the narrow spectral width of the Raman E-2(h) vibrational mode, and the position of the photoluminescence band close to the fundamental band gap of InN.

TI Wire ablation dynamics model and its application to imploding wire

AB The paper presents an extended description of the amplified wire ablation dynamics model (WADM), which accounts in a single simulation for the processes of wire ablation and implosion of a wire array load of arbitrary geometry and wire material composition. To investigate the role of wire ablation effects, the implosions of cylindrical and planar wire array loads at the university based generators Cobra (Cornell University) and Zebra (University of Nevada, Reno) have been analyzed. The analysis of the experimental data shows that the wire mass ablation rate can be described as a function of the current through the wire and some coefficient defined by the wire material properties. The aluminum wires were found to ablate with the highest rate, while the copper ablation is the slowest one. The lower wire ablation rate results in a higher inward velocity of the ablated plasma, a higher rate of the energy coupling with the ablated plasma, and a more significant delay of implosion for a heavy load due to the ablation effects, which manifest the most in a cylindrical array configuration and almost vanish in a single-planar array configuration. The WADM is an efficient tool suited for wire array load design and optimization in wide parameter ranges, including the loads with specific properties needed for the inertial confinement fusion research and laboratory astrophysics experiments. The data output from the WADM simulation can be used to simplify the radiation magnetohydrodynamics modeling of the wire array plasma.

AB We report on the detection of high-energy gamma-ray emission from the Moon during the first 24 months of observations by the Fermi Large Area Telescope (LAT). This emission comes from particle cascades produced by cosmic-ray (CR) nuclei and electrons interacting with the lunar surface. The differential spectrum of the Moon is soft and can be described as a log-parabolic function with an effective cutoff at 2-3 GeV, while the average integral flux measured with the LAT from the beginning of observations in 2008 August to the end of 2010 August is F(> 100 MeV) = (1.04 +/- 0.01 [statistical error] +/- 0.1 [systematic error]) x 10(-6) cm(-2) s(-1). This flux is about a factor 2-3 higher than that observed between 1991 and 1994 by the EGRET experiment on board the Compton Gamma Ray Observatory, F(> 100 MeV) approximate to 5 x 10(-7) cm-2 s-1, when solar activity was relatively high. The higher gamma-ray flux measured by Fermi is consistent with the deep solar minimum conditions during the first 24 months of the mission, which reduced effects of heliospheric modulation, and thus increased the heliospheric flux of Galactic CRs. A detailed comparison of the light curve with McMurdo Neutron Monitor rates suggests a correlation of the trends. The Moon and the Sun are so far the only known bright emitters of gamma-rays with fast celestial motion. Their paths across the sky are projected onto the Galactic center and high Galactic latitudes as well as onto other areas crowded with high-energy gamma-ray sources. Analysis of the lunar and solar emission may thus be important for studies of weak and transient sources near the ecliptic.

AB We analyze blazar jet apparent speeds and accelerations from the RDV series of astrometric and geodetic very long baseline interferometry (VLBI) experiments. From these experiments, we have produced and analyzed 2753 global VLBI images of 68 sources at 8 GHz with a median beam size of 0.9 milliarcseconds (mas) and a median of 43 epochs per source. From this sample, we analyze the motions of 225 jet components in 66 sources. The distribution of the fastest measured apparent speed in each source has a median of 8.3c and a maximum of 44c. Sources in the 2FGL Fermi LAT catalog display higher apparent speeds than those that have not been detected. On average, components farther from the core in a given source have significantly higher apparent speeds than components closer to the core; for example, for a typical source, components at similar to 3 mas from the core (similar to 15 pc projected at z similar to 0.5) have apparent speeds about 50% higher than those of components at similar to 1 mas from the core (similar to 5 pc projected at z similar to 0.5). We measure accelerations of components in orthogonal directions parallel and perpendicular to their average velocity vector. Parallel accelerations have significantly larger magnitudes than perpendicular accelerations, implying that observed accelerations are predominantly due to changes in the Lorentz factor (bulk or pattern) rather than projection effects from jet bending. Positive parallel accelerations are significantly more common than negative ones, so the Lorentz factor (bulk or pattern) tends to increase on the scales observed here. Observed parallel accelerations correspond to modest source frame increases in the bulk or pattern Lorentz factor.

AB We report on the determination of radial magnetic field strength in the heliocentric distance range from 6 to 120 solar radii (R-circle dot) using data from Coronagraph 2 (COR2) and Heliospheric Imager I (HI1) instruments on board the Solar Terrestrial Relations Observatory spacecraft following the standoff-distance method of Gopalswamy & Yashiro. We measured the shock standoff distance of the 2008 April 5 coronal mass ejection (CME) and determined the flux-rope curvature by fitting the three-dimensional shape of the CME using the Graduated Cylindrical Shell model. The radial magnetic field strength is computed from the Alfven speed and the density of the ambient medium. We also compare the derived magnetic field strength with in situ measurements made by the Helios spacecraft, which measured the magnetic field at the heliocentric distance range from 60 to 215 R-circle dot. We found that the radial magnetic field strength decreases from 28 mG at 6 R-circle dot to 0.17 mG at 120 R-circle dot. In addition, we found that the radial profile can be described by a power law.

AB We present results from a study of nuclear emission from a nearby radio galaxy, 4C+29.30, over a broad 0.5-200 keV X-ray band. This study used new XMM-Newton (similar to 17 ks) and Chandra (similar to 300 ks) data, and archival Swift/BAT data from the 58 month catalog. The hard (>2 keV) X-ray spectrum of 4C+29.30 can be decomposed into an intrinsic hard power law (Gamma similar to 1.56) modified by a cold absorber with an intrinsic column density N-H,N- z similar to 5 x 10(23) cm(-2), and its reflection (vertical bar Omega/2 pi vertical bar similar to 0.3) from a neutral matter including a narrow iron K alpha emission line at a rest-frame energy similar to 6.4 keV. The reflected component is less absorbed than the intrinsic one with an upper limit on the absorbing column of N-H, z(refl) < 2.5 x 10(22) cm(-2). The X-ray spectrum varied between the XMM-Newton and Chandra observations. We show that a scenario invoking variations of the normalization of the power law is favored over a model with variable intrinsic column density. X-rays in the 0.5-2 keV band are dominated by diffuse emission modeled with a thermal bremsstrahlung component with temperature similar to 0.7 keV, and contain only a marginal contribution from the scattered power-law component. We hypothesize that 4C+29.30 belongs to a class of "hidden" active galactic nuclei containing a geometrically thick torus. However, unlike the majority of hidden AGNs, 4C+29.30 is radio-loud. Correlations between the scattering fraction and Eddington luminosity ratio, and between black hole mass and stellar velocity dispersion, imply that 4C+29.30 hosts a black hole with similar to 10(8) M-circle dot mass.

AB We investigate the dynamics of photoinduced index changes in chalcogenide As2S3 fibers. Using a novel phase sensitive technique for measuring the photoinduced index change, we find that the index evolution is a two-stage process: it consists of a fast reduction and a subsequent slow increase in the refractive index. We show that the index change depends strongly on the beam intensity with both positive and negative changes possible. These findings can have application in design and fabrication of photoinduced devices such as Bragg gratings and photonic cavities. (C) 2012 Optical Society of America

AB Solid oxide fuels cells (SOFCs) are promising devices for versatile and efficient power generation with fuel flexibility, but viability ability is contingent upon understanding chemical and material processes to improve their performance and durability. Newly developed in situ optical methods provide new insight into how carbon deposition varies with different hydrocarbon and alcohol fuels and depends on operating conditions. Some findings, such as heavier hydrocarbon fuels forming more carbon than lighter fuels, are expected, but other discoveries are surprising. For example, methanol shows a greater tendency to form carbon deposits than methane at temperatures below 800 degrees C, and kinetically controlled steam reforming with ethanol at high temperatures (similar to 800 degrees C) is less detrimental to SOFC performance than operating the device with dry methanol as the fuel.

TI CEDAR Electrodynamics Thermosphere Ionosphere (ETI) Challenge for

ID LOWER ATMOSPHERE; PROFILES; MIDDLE
AB In an effort to quantitatively assess the current capabilities of Ionosphere/Thermosphere (IT) models, an IT model validation study using metrics was performed. This study is a main part of the CEDAR Electrodynamics Thermosphere Ionosphere (ETI) Challenge, which was initiated at the CEDAR workshop in 2009 to better comprehend strengths and weaknesses of models in predicting the IT system, and to trace improvements in ionospheric/thermospheric specification and forecast. For the challenge, two strong geomagnetic storms, four moderate storms, and three quiet time intervals were selected. For the selected events, we obtained four scores (i.e., RMS error, prediction efficiency, ratio of the maximum change in amplitudes, and ratio of the maximum amplitudes) to compare the performance of models in reproducing the selected physical parameters such as vertical drifts, electron and neutral densities, NmF2, and hmF2. In this paper, we present the results from comparing modeled values against space-based measurements including NmF2 and hmF2 from the CHAMP and COSMIC satellites, and electron and neutral densities at the CHAMP satellite locations. It is found that the accuracy of models varies with the metrics used, latitude and geomagnetic activity level.

TI Propagation of gamma rays and production of free electrons in air
SO JOURNAL OF APPLIED PHYSICS
LA English
DT Article
ID AVERAGE ENERGY; ION PAIR; GASES
AB This paper is devoted to the analysis of production of free electrons in air by gamma-rays leaking from radioactive materials. A model based on the Klein-Nishina scattering theory is used to calculate scattering cross sections and approximate the electron production rate. The model includes the effects of primary gamma-quanta radiated by the source as well as that scattered in air. Comparison of the model with the MCNPX kinetic code (http://mcnpx.lanl.gov/) in a sample problem shows excellent agreement. The motivation for this research comes from the recently proposed concept of remote detection of concealed radioactive materials [V. L. Granatstein and G. S. Nusinovich, J. Appl. Phys. 108, 063304 (2010)]. The concept is based on the breakdown in air at the focal point of a high-power beam of electromagnetic waves produced by a THz gyrotron with a 10-20 mu s pulse. The presence of a radioactive material can greatly exceed the production rate of free electrons over the natural background rate. Additional electrons act as seeds to initiate the breakdown and create sufficiently dense plasma at the focal region. The dense plasma can then be remotely detected as an unambiguous effect of the concealed radioactive material. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4762007]

Concentrations of H:Pd (D:Pd) up to 1:1 in 0.1 M LiOH (LiOD) in H2O (D2O) electrolyte were obtained, as determined by both the Pd lattice parameter and cathode resistivity. In addition, some indications on the kinetics of loading and deloading of hydrogen from the Pd surface were obtained.

AB This paper describes a unified, element based Galerkin (EBG) framework for a three-dimensional, nonhydrostatic model for the atmosphere. In general, EBG methods possess high-order accuracy, geometric flexibility, excellent dispersion properties and good scalability. Our nonhydrostatic model, based on the compressible Euler equations, is appropriate for both limited-area and global atmospheric simulations. Both a continuous Galerkin (CG), or spectral element, and discontinuous Galerkin (DG) model are considered using hexahedral elements. The formulation is suitable for both global and limited-area atmospheric modeling, although we restrict our attention to 3D limited-area phenomena in this study; global atmospheric simulations will be presented in a follow-up paper. Domain decomposition and communication algorithms used by both our CG and DG models are presented. The communication volume and exchange algorithms for CG and DG are compared and contrasted. Numerical verification of the model was performed using two test cases: flow past a 3D mountain and buoyant convection of a bubble in a neutral atmosphere; these tests indicate that both CG and DG can simulate the necessary physics of dry atmospheric dynamics. Scalability of both methods is shown up to 8192 CPU cores, with near ideal scaling for DG up to 32,768 cores. (C) 2012 Elsevier Inc. All rights reserved.

AB We report on the characterization of two-dimensionally confined phonon-polaritons at terahertz frequencies in suspended waveguides using Raman scattering. The cross-sectional dimensions of the waveguides are commensurate with the wavelength of the phonon-polariton in forward scattering leading to Raman spectra that depend strongly on the physical size of the waveguide. We use finite element numerical computations to predict the polariton frequencies and find excellent agreement with measurements. Our observations and analysis advance the understanding of polariton propagation in guiding geometries and also have significant practical implications in integrated terahertz generation and stimulated Raman amplification.

AB A field test of emulsified zero valent iron (EZVI) nanoparticles was conducted at Parris Island, SC, USA and was monitored for two and half years to assess the treatment of subsurface-source zone chlorinated volatile organic compounds (CVOCs) dominated by tetrachloroethene (PCE) and its chlorinated daughter products. Two EZVI delivery methods were used: pneumatic injection and direct injection. In the pneumatic injection plot, 2180 L of EZVI containing 225 kg of iron (Toda RNIP-10DS), 856 kg of corn oil, and 22.5 kg of surfactant were injected to remedy an estimated 38 kg of CVOCs. In the direct injection plot, 572 L of EZVI were injected to treat an estimated 0.155 kg of CVOCs. After injection of the EZVI, significant reductions in PCE and trichloroethene (TCE) concentrations were observed in downgradient wells with corresponding increases in degradation products including significant increases in ethene. In the pneumatic injection plot, there were significant reductions in the downgradient groundwater mass flux values for PCE (>85%) and TCE (>85%) and a significant increase in the mass flux of ethene. There were significant reductions in total CVOC mass (86%); an estimated reduction of 63% in the sorbed and dissolved phases and 93% reduction in the PCE DNAPL mass. There are uncertainties in these estimates because DNAPL may have been mobilized during and after injection. Following injection, significant increases in dissolved sulfide, volatile fatty acids (VFA), and total organic carbon (TOC) were observed. In contrast, dissolved sulfate and pH decreased in many wells. The apparent effective remediation seems to have been accomplished by direct abiotic dechlorination by nanoiron followed by biological reductive dechlorination stimulated by the corn oil in the emulsion.

AB We use cyclic and rotating disk electrode voltammetry to study glycol-based coolant formulations to show that individual constituents have either negligible or significant poisoning effects on the nanoscale Pt/carbon catalysts used in proton exchange membrane fuel cells. The base fluid in all these coolants is glycol (1, 3 propanediol), commercially available in a BioGlycol coolant formulation with an ethoxylated nonylphenol surfactant, and azole- and polyol-based non-ionic corrosion inhibitors. Exposure of a Pt/Vulcan carbon electrode to glycol-water or glycol-water-surfactant mixtures causes the loss of Pt electrochemical surface area (ECSA), but the Pt ECSA is fully recovered in clean electrolyte. Only mixtures with the azole corrosion inhibitor cause irreversible losses to the Pt ECSA and oxygen reduction reaction (ORR) activity. The Pt ECSA and ORR activity can only be recovered to within 70% of its initial values after aggressive voltammetric cycling to 1.50 V after azole poisoning. When poisoned with a glycol mixture containing the polyol corrosion inhibitor instead, the Pt ECSA and ORR activity is completely recovered by exposure to a clean electrolyte. The results suggest that prior to incorporation in a fuel cell, voltammetric evaluation of the constituents of coolant formulations is worthwhile. (C) 2012 Elsevier B.V. All rights reserved.

AB Several N-polar GaN/AlGaN/GaN heterostructures intended for high electron mobility transistor (HEMT) devices were grown by molecular beam epitaxy using either SiC or freestanding GaN substrates. The microstructure of these heterostructures has been compared using transmission electron microscopy and associated analytical techniques. Considerable 1:1 ordering was observed within the AlxGa1-xN layers (where x similar to 0.34-0.37) for both substrate types. Threading dislocations were the most common defects observed in structures grown on SiC substrates, whereas interfacial misfit dislocations and surface pits were the primary defects observed in samples grown on the freestanding GaN substrates.

AB The local ensemble transform (ET) analysis perturbation scheme is adapted to generate perturbations to both atmospheric variables and sea-surface temperature (SST). The adapted local ET scheme is used in conjunction with a prognostic model of SST diurnal variation and the Navy Operational Global Atmospheric Prediction System (NOGAPS) global spectral model to generate a medium-range forecast ensemble. When compared to a control ensemble, the new forecast ensemble with SST variation exhibits notable differences in various physical properties including the spatial patterns of surface fluxes, outgoing longwave radiation (OLR), cloud radiative forcing, near-surface air temperature and wind speed, and 24-h accumulated precipitation. The structure of the daily cycle of precipitation also is substantially changed, generally exhibiting a more realistic midday peak of precipitation. Diagnostics of ensemble performance indicate that the inclusion of SST variation is very favorable to forecasts in the Tropics. The forecast ensemble with SST variation outscores the control ensemble in the Tropics across a broad set of metrics and variables. The SST variation has much less impact in the Midlatitudes. Further comparison shows that SST diurnal variation and the SST analysis perturbations are each individually beneficial to the forecast from an overall standpoint. The SST analysis perturbations have broader benefit in the Tropics than the SST diurnal variation, and inclusion of the SST analysis perturbations together with the SST diurnal variation is essential to realize the greatest gains in forecast performance.

SO RADIO SCIENCE

DT Article
ID RADIO INTERFEROMETER
AB The results of a climatological study of ionospheric disturbances derived from observations of cosmic sources from the Very Large Array (VLA) Low-frequency Sky Survey (VLSS) are presented. We have used the ionospheric corrections applied to the 74 MHz interferometric data within the VLSS imaging process to obtain fluctuation spectra for the total electron content (TEC) gradient on spatial scales from a few to hundreds of kilometers and temporal scales from less than one minute to nearly an hour. The observations sample nearly all times of day and all seasons. They also span latitudes and longitudes from 28 degrees N to 40 degrees N and 95 degrees W to 114 degrees W, respectively. We have binned and averaged the fluctuation spectra according to time of day, season, and geomagnetic (K-p index) and solar (F10.7) activity. These spectra provide a detailed, multiscale account of seasonal and intraday variations in ionospheric activity with wavelike structures detected at wavelengths between about 35 and 250 km. In some cases, trends between spectral power and K-p index and/or F10.7 are also apparent. In addition, the VLSS observations allow for measurements of the turbulent power spectrum down to periods of 40 s (scales of similar to 0.4 km at the height of the E-region). While the level of turbulent activity does not appear to have a strong dependence on either K-p index or F10.7, it does appear to be more pronounced during the winter daytime, summer nighttime, and near dusk during the spring.

Strong surface segregation of hydrogen with a depletion zone behind is observed in the palladium hydride nanowires. We also show that lattice reorientation is controlled by the hydrogen concentration as well as the nanowire size. The interplay of surface stresses and hydrogen induced stresses is responsible for the observations. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4757999]

space shuttle's final launch

ID WATER-VAPOR; ODIN SATELLITE; ART.; ICE; INSTRUMENT; DESIGN; NLC
AB The space shuttle launched for the last time on 8 July 2011. As with most shuttle launches, the three main engines injected about 350 t of water vapor between 100 and 115 km off the east coast of the United States during its ascent to orbit. We follow the motion of this exhaust with a variety of satellite and ground-based data sets and find that (1) the shuttle water vapor plume spread out horizontally in all directions over a distance of 3000 to 4000 km in 18 h, (2) a portion of the plume reached northern Europe in 21 h to form polar mesospheric clouds (PMCs) that are brighter than over 99% of all PMCs observed in that region, and (3) the observed altitude dependence of the particle size is reversed with larger particles above smaller particles. We use a one- dimensional cloud formation model initialized with predictions of a plume diffusion model to simulate the unusually bright PMCs. We find that eddy mixing can move the plume water vapor down to the mesopause near 90 km where ice particles can form. If the eddy diffusion coefficient is 400 to 1000 m(2)/s, the predicted integrated cloud brightness is in agreement with both satellite and ground-based observations of the shuttle PMCs. The propellant mass of the shuttle is about 20% of that from all vehicles launched during the northern 2011 PMC season. We suggest that the brightest PMC population near 70 degrees N is formed by space traffic exhaust.

ID RADIO-WAVES; DRIFT MEASUREMENTS; AIRGLOW; MODEL
AB We report on satellite observations of plasma density enhancements (ducts) in the topside ionosphere during four HAARP/BRIOCHE campaigns during 2009-2010. Artificial ducts, caused by high-power HF radio wave injections from the HAARP transmitter toward the magnetic zenith, are detected by the DEMETER and DMSP satellites on a regular basis when there is a perceptible ionospheric F-2 peak density. Overall, the plasma density enhancements detected between 0930 and 1230 LT varied from 3-13%, while those during similar to 1730-2215 LT were typically 15-40%. We also used a modified SAMI2 model to study the artificial ducts' mechanism driven by HF electron heating in the bottomside F-2 region. The heating builds up the plasma pressure, thus pushing plasma along the magnetic field. The simulation results performed for the input parameters similar to the conditions of the heating experiments are in fair agreement with the pertinent observations. The ducts seem to be produced most efficiently for heating frequencies quite close to the critical frequency f(o)F(2).

Metalloporphyrin variants were generated based on a Deuteroporphyrin IX 2,4 bis-ethylene glycol functionalized sorbent. The copper(II) variant removed phosgene at rates significantly higher than that of the bare sorbent. It was further demonstrated that the sorbent was reusable and that illumination resulted in additional target removal. The column effluent from the Cu(II) functionalized sorbent was shown to contain chloride: however, the levels were significantly less than would be expected based on a mass balance.

AB Many theorists argue that the probabilities of unique events, even real possibilities such as President Obama's re-election, are meaningless. As a consequence, psychologists have seldom investigated them. We propose a new theory (implemented in a computer program) in which such estimates depend on an intuitive non-numerical system capable only of simple procedures, and a deliberative system that maps intuitions into numbers. The theory predicts that estimates of the probabilities of conjunctions should often tend to split the difference between the probabilities of the two conjuncts. We report two experiments showing that individuals commit such violations of the probability calculus, and corroborating other predictions of the theory, e. g., individuals err in the same way even when they make non-numerical verbal estimates, such as that an event is highly improbable.

ID GRAPHENE NANORIBBONS; CHAINS; LIQUID; WAVE
AB The step edges on the Si(553)-Au surface undergo a 1x3 reconstruction at low temperature which has recently been interpreted theoretically as the x3 ordering of spin-polarized silicon atoms at the edges of the graphitic Si nanowires on this vicinal surface. This predicted magnetic ground state has a clear spectroscopic signature-a silicon step-edge state at 0.5 eV above the Fermi level-that arises from strong exchange splitting and hence would not occur without spin polarization. Here we report spatially resolved scanning tunneling spectroscopy data for these nanowires. At low temperature we find an unoccupied state at 0.5 eV above every third ste-pedge silicon atom, in excellent agreement with the spin-polarized ground state predicted theoretically. This spin-polarized state survives up to room temperature where the position of the spins rapidly fluctuates among all Si step-edge sites.

TI Coherent perfect absorption in epsilon-near-zero metamaterials
SO PHYSICAL REVIEW B

AB In conventional materials, strong absorption usually requires that the material have either high loss or a large thickness-to-wavelength ratio (d/lambda >> 1). We find the situation to be vastly different for bilayer structures composed of ametallic substrate and an anisotropic epsilon-near-zero (ENZ) metamaterial, where the permittivity in the direction perpendicular to its surface, epsilon(z), vanishes. Remarkably, perfect absorption can occur in situations where the metamaterial is arbitrarily thin (d/lambda << 1) and arbitrarily low loss. Our numerical and analytical solutions reveal that under the conditions epsilon(z) -> 0 and J(epsilon(z)) >> R(epsilon(z)), at perfect absorption there is a linear relationship between the thickness and the loss, which means the thickness of the absorber can be pushed to zero by reducing the material loss to zero. This counterintuitive behavior is explained in terms of coherent perfect absorption (or stimulated absorption) via critical coupling to a fast wave propagating along the ENZ layer.

AB Soft elastomeric materials that mimic real soft human tissues are sought to provide realistic experimental devices to simulate the human body's response to blast loading to aid the development of more effective protective equipment. The dynamic mechanical behavior of these materials is often measured using a Kolsky bar because it can achieve both the high strain rates (>100 s(-1)) and the large strains (>20%) that prevail in blast scenarios. Obtaining valid results is challenging, however, due to poor dynamic equilibrium, friction, and inertial effects. To avoid these difficulties, an inverse method was employed to determine the dynamic response of a soft, prospective biomimetic elastomer using Kolsky bar tests coupled with high-speed 3D digital image correlation. Individual tests were modeled using finite elements, and the dynamic stiffness of the elastomer was identified by matching the simulation results with test data using numerical optimization. Using this method, the average dynamic response was found to be nearly equivalent to the quasi-static response measured with stress-strain curves at compressive strains up to 60%, with an uncertainty of +/- 18%. Moreover, the behavior was consistent with the results in stress relaxation experiments and oscillatory tests although the latter were performed at lower strain levels. Published by Elsevier Ltd.

AB Nanoporous alumina templates and titania nanotube arrays have emerged as highly important materials due to their many potential applications in a variety of research areas. The templates are prepared using an electrochemical anodization process starting from metallic Al or Ti films. Several different synthesis routes for the deposition of such templates have been demonstrated in literature. This article provides an overview of the various synthesis routes that may be employed. The templates have diverse applications and may also be utilized in the electrodeposition of nanowire arrays of a variety of materials, such as metals, semiconductors, etc. A brief overview of these deposition methods is also provided.

AB A lumped parameter equivalent circuit basis for calculating and allocating heat power sources in a transducer is presented along with experimental results. The simple model allows heat power calculations at resonance based on readily attainable parameters for transducers with uniform fields. Measured and finite element analysis of steady state thermal results are compared for the monopole mode of the single crystal driven modal transducer projector. The model serves as a physical and computational aid in the evaluation of piezoelectric transducer heating and may be used for evaluating highly coupled single crystal as well as ceramic piezoelectric transducers.

STRATIFIED FLOW; EXPANSIONS; EQUATIONS
AB A modeling and simulation study is performed in a littoral ocean waveguide subject to uncertainty in four quantities: source depth, tidal forcing, initial thermocline structure, and sediment sound speed. In this partially known shelf-break environment, tidal forcing over a density-stratified water column produces internal tides and solitary wave packets. The resulting uncertainty in the space-time oceanographic field is mapped into the sound speed distribution which, in turn, introduces uncertainty into the acoustic wave field. The latter is treated as a stochastic field whose intensity is described by a polynomial chaos expansion. The expansion coefficients are estimated through constrained multivariate linear regression, and an analysis of the chaos coefficients provides insight into the relative contribution of the uncertain acoustic and oceanographic quantities. Histograms of acoustic intensity are estimated and compared to a reference solution obtained through Latin Hypercube sampling. A sensitivity analysis is performed to illustrate the relative importance of the four contributions of incomplete information about the environment. The simulation methodology represents an end-to-end analysis approach including both oceanographic and acoustic field uncertainty where the latter is quantified using stochastic basis expansions in the form of a polynomial chaos representation.

AB During a recent experiment in Kauai, Hawaii, reciprocal transmissions were conducted between two acoustic transceivers mounted on the seafloor at a depth of 100 m. The passage of moving surface wave crests was shown to generate focused and intense coherent acoustic returns, which had increasing or decreasing delay depending on the direction of propagation relative to the direction of surface wave crests. It is shown that a rough surface two-dimensional parabolic equation model with an evolving sea surface can produce qualitative agreement with data for the dynamic surface returns.

AB Absorption features from K-shell aluminum z-pinch plasmas have recently been studied on Zebra, the 1.7 MA pulse power generator at the Nevada Terawatt Facility. In particular, tungsten plasma has been used as a semi-backlighter source in the generation of aluminum K-shell absorption spectra by placing a single Al wire at or near the end of a single planar W array. All spectroscopic experimental results were recorded using a time-integrated, spatially resolved convex potassium hydrogen phthalate (KAP) crystal spectrometer. Other diagnostics used to study these plasmas included x-ray detectors, optical imaging, laser shadowgraphy, and time-gated and time-integrated x-ray pinhole imagers. Through comparisons with previous publications, Al K-shell absorption lines are shown to be from much lower electron temperature (similar to 10-40 eV) plasmas than emission spectra (similar to 350-500 eV).

AB Close to an x-ray filter's K-edge the transmission depends strongly on the photon energy. For a few atom pairs, the K-edge of one is only a few tens of eV higher than a K-line energy of another, so that a small change in the line's energy becomes a measurable change in intensity behind such a matching filter. Lutetium's K-edge is similar or equal to 27 eV above iridium's K alpha(2) line, similar or equal to 63.287 keV for cold Ir. A Lu filter reduces this line's intensity by similar or equal to 10 % when it is emitted by a plasma, indicating an ionization shift Delta epsilon similar or equal to 10 +/- 1 eV.

AB A high-resolution x-ray spectrometer utilizing a thin quartz transmission crystal and covering the 6 keV-18 keV energy range has been developed and tested. The spectrometer consists of a cylindrically bent crystal in a vacuum housing. The crystal position and the range of Bragg angles that are incident on the crystal can be adjusted to record an approximate to 4 keV wide spectrum in the 6 keV-18 keV range. The spectrometer is of the Cauchois type and has a compact linear geometry that is convenient for deployment at laser-produced plasma, EBIT, and other x-ray sources. Test spectra of the W L and Mo K lines from laboratory sources have linewidths as small as 11 eV, approaching the natural widths, and instrumental resolving power as high as 1800. Techniques for enhancing the energy resolution are experimentally demonstrated. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4732184]

TI REGULARIZATION OF TUNNELING RATES WITH QUANTUM CHAOS
SO INTERNATIONAL JOURNAL OF BIFURCATION AND CHAOS
LA English
DT Article
DE Quantum; chaos; tunneling; billiards
ID POINCARE SECTIONS; ELEMENT
AB We study tunneling in various shaped, closed, two-dimensional, flat-potential, double wells by calculating the energy splitting between symmetric and antisymmetric state pairs. For shapes that have regular or nearly regular classical behavior (e. g. rectangular or circular) the tunneling rates vary greatly over wide ranges often by several orders of magnitude. However, for well shapes that admit more classically chaotic behavior (e. g. the stadium, the Sinai billiard) the range of tunneling rates narrows, often by orders of magnitude. This dramatic narrowing appears to come from destabilization of periodic orbits in the regular wells that produce the largest and smallest tunneling rates and causes the splitting versus energy relation to take on a possibly universal shape. It is in this sense that we say the quantum chaos regularizes the tunneling rates.

ID UNDERWATER ACOUSTIC COMMUNICATIONS; PASSIVE-PHASE CONJUGATION;
COMMUNICATION; SYSTEMS
AB Time-reversed orthogonal frequency division multiplexing (TR-OFDM) has recently received attention as a promising scheme for supporting single-input multiple-output communications over time-dispersive fading channels with high bandwidth efficiency. In TR-OFDM, the use of passive time reversal processing offers a simple means of reducing channel time dispersion. Consequently, a cyclic prefix (CP) with a length shorter than the channel order can be used without inducing much inter-block interference (IBI). This paper tackles a technical challenge critical to the success of TR-OFDM, that is, how to minimize the CP length while satisfying certain performance requirements. Based on a data model derived for TR-OFDM, a quantitative relationship between the CP length and error performance is first established and a design procedure is then proposed. Our design reveals that the optimal CP length depends on the power delay profiles of underlying channels. Our design also leads to new insight in the time reversal operation and helps identify channel situations where TR-OFDM might not work effectively. The merits of our design are confirmed by both theoretical analysis and numerical simulations.

AB Preliminary Atacama Large Millimeter/Submillimeter Array (ALMA) science verification data for a single pixel centered on the hot core of Orion KL (R. A. = 05 h 35 m 14.35 s, Dec = -05 degrees 22'35 '' (J2000)) are available as this special issue on broadband spectroscopy is coming to press. As part of this verification process it is useful to compare simulations based on laboratory spectroscopy with ALMA results. This provides not only a test of instrumentation and analysis, but also a test of astrophysical assumptions such as local thermodynamic equilibrium (LIE) and the temperature variations within telescope beams. However, these tests are spectroscopically limited because it is well known that astrophysical spectra contain large numbers of unknown lines, many of which are presumably due to unanalyzed rotational spectra in excited vibrational states of a relatively few molecules. To address this issue we have previously discussed the use of broadband complete experimental spectra (CES) that is obtained from the analysis of several hundred intensity calibrated spectra taken over a range of temperatures. In this paper we will compare these CES with the similarly complete astrophysical spectra. (C) 2012 Elsevier Inc. All rights reserved.

AB In complex environments, the ability to identify the constituent chemicals within a mixture is extremely important. By utilizing a Pearson correlation algorithm to compare sets of multi-wavelength resonance-Raman signatures, we demonstrate the automated identification of chemicals within a mixture. Applying a linear mixture model, we are also able to estimate the fractional volumetric abundances contained therein. The multi-wavelength resonance-Raman signature used for identification is obtained by illuminating the unknown mixture with a series of 21 sequential laser wavelengths. This signature is then compared with the signatures of a set of known chemicals. By maximizing the Pearson correlation coefficient between the signature of the mixture and a weighted superposition of the signatures of the pure chemicals, we are able to determine the mixture components with 100% accuracy. The linear superposition of the selected chemicals, which minimizes the least squares distance between the signatures of the mixture, and its mathematical recreation determines the corresponding fraction, by volume, of each chemical within the mixture.

At sub-megabar shock pressure, planar jets manifesting the development of the Richtmyer-Meshkov-type instability in a non-accelerated target are observed. As the shock pressure exceeds 1 Mbar, an oscillatory rippled expansion wave is observed, followed by the "feedout" of the rear-surface perturbations to the ablation front and the development of the Rayleigh-Taylor instability, which breaks up the accelerated target.

TI Co-existence of whistler waves with kinetic Alfven wave turbulence for
the high-beta solar wind plasma
SO PHYSICS OF PLASMAS
LA English
DT Article
ID CASCADE
AB It is shown that the dispersion relation for whistler waves is identical for a high or low beta plasma. Furthermore, in the high-beta solar wind plasma, whistler waves meet the Landau resonance with electrons for velocities less than the thermal speed, and consequently, the electric force is small compared to the mirror force. As whistlers propagate through the inhomogeneous solar wind, the perpendicular wave number increases through refraction, increasing the Landau damping rate. However, the whistlers can survive because the background kinetic Alfven wave (KAW) turbulence creates a plateau by quasilinear (QL) diffusion in the solar wind electron distribution at small velocities. It is found that for whistler energy density of only similar to 10(-3) that of the kinetic Alfven waves, the quasilinear diffusion rate due to whistlers is comparable to KAW. Thus, very small amplitude whistler turbulence can have a significant consequence on the evolution of the solar wind electron distribution function. (C) 2012 American Institute of Physics.

AB For some high atomic number atoms, the energy of the K-edge is tens of eVs higher than the K-line energy of another atom, so that a few eV increase in the line's energy results in a decreasing transmission of the x-ray through a filter of the matching material. The transmission of cold iridium's similar or equal to 63: 287 keV K alpha(2) line through a lutetium filter is 7% lower when emitted by ionized iridium, consistent with an energy increase of Delta epsilon similar or equal to 10 +/- 1 eV associated with the ionization. Likewise, the transmission of the K beta(1) line of ytterbium through a near-coincident K-edge filter changes depending on plasma parameters that should affect the ionization. Systematic exploration of filter-line pairs like these could become a unique tool for diagnostics of suitable high energy density plasmas. (C) 2012 American Institute of Physics.

AB We describe an "active" antenna system for HF/VHF (long wavelength) radio astronomy that has been successfully deployed 256-fold as the first station (LWA1) of the planned Long Wavelength Array. The antenna system, consisting of crossed dipoles, an active balun/preamp, a support structure, and a ground screen has been shown to successfully operate over at least the band from 20 MHz (15 m wavelength) to 80 MHz (3.75 m wavelength) with a noise figure that is at least 6 dB better than the Galactic background emission-noise temperature over that band. Thus, we met the goal to design and construct a compact, inexpensive, rugged, and easily assembled antenna system that can be deployed many-fold to form numerous large individual "stations" for the purpose of building a large, long wavelength synthesis array telescope for radio astronomical and ionospheric observations.

AB Context. We report the detection of oxygen-rich circumstellar envelopes in stars of the nearby (700 kpc) starburst galaxy IC 10. The star-formation history and the chemical environment of this galaxy make it an ideal target to observe dust production by massive stars in a metal-poor environment.
Aims. The goal of this study is to identify oxygen-rich stars in IC 10 and to constrain their nature between asymptotic giant branch stars (AGBs), red supergiants (RSGs), and other bright infrared sources. We examine the mass-loss rates of the stars and compare to results obtained for the Magellanic Clouds. Our objectives are to (1) assess whether RSGs can be significant dust producers in IC 10, and (2), solve the discrepancy between the star-formation history of IC 10 and the relatively low number of RSGs detected in the optical.
Methods. We search for silicate dust in emission by using the spectral map observed with the Infrared Spectrograph on board the Spitzer Space Telescope. The optical (UBVRI) and infrared (JHK, Spitzer/IRAC and Spitzer/MIPS) photometry are used to assert the membership of the stars to IC 10 and distinguish between AGBs and RSGs. Radiative models are used to infer mass-loss rates and stellar luminosities.
Results. The luminosity and colors of at least 9 silicate emission sources are consistent with stars within IC 10. Furthermore, the photometry of 2 of these sources is consistent with RSGs. We derive dust mass-loss rates similar to the values found in the Magellanic Clouds. Accounting for the sample completeness, RSGs are not important contributors to the dust mass budget in IC 10.

AB A study to investigate the use of the acoustic vector field, separately or in combination with the scalar field, to invert for geoacoustic properties of the seafloor was conducted. The analysis was performed in the context of the 2004 Sediment Acoustics Experiment (SAX04) conducted in the Northern Gulf of Mexico (GOM) where a small number of acoustic vector sensors were deployed in close proximity to the seafloor. The acoustic vector sensors were located both above and beneath the seafloor interface where they measured the acoustic pressure and the acoustic particle acceleration. A variety of acoustic waveforms were transmitted into the seafloor at normal incidence. Motion data provided by the buried vector sensors were affected by a suspension response that was sensitive to the mass properties of the sensor, the sediment density, and shear wave speed. The suspension response for the buried vector sensors included a resonance within the analysis band of 0.4-2.0 kHz. The response was sufficiently sensitive to the local geoacoustic properties, that it was integrated into the inverse methods developed for this study. Inversions of real and synthetic data sets showed that information about sediment shear wave speed was carried by the suspension response of the buried sensors, as opposed to being contained inherently within the vector acoustic field.

ID INTERFERENCE MITIGATION; WIRELESS NETWORKS; COMMUNICATION; EQUALIZATION
AB In this paper, we investigate the multicarrier transmission in one particular type of underwater acoustic channels, which have extremely long delay spreads (e. g., around 1 s) but clustered multipath arrivals (e. g., two clusters). These channels show up in certain practical scenarios, such as in the deep-water horizontal transmissions and in the underwater broadcasting networks, and introduce both interblock interference and intercarrier interference (IBI/ICI) in the received signal. For joint IBI and ICI mitigation, we propose a factor-graph-based equalization method, in which estimation of information symbols is performed via messages passing over a well-designed graph. We also present a sparse channel estimator by treating the two clusters of the long channel as two virtual quasi-synchronous channels. Both channel estimation and equalization are integrated into a progressive receiver framework. Simulation and experimental results are provided to validate the receiver performance in both deep-water horizontal channels and underwater broadcasting networks.

AB Analyses of thermodynamic data gathered from airborne dropwindsondes released from the upper troposphere during the Pre-Depression Investigation of Cloud Systems in the Tropics (PREDICT) experiment are presented. We focus on two systems that finally became hurricanes Karl and Matthew, and one system (Gaston) that attained tropical storm status, but subsequently weakened and never redeveloped during five days of monitoring. Data for all events show that the largest values of total precipitable water are collocated with the surface trough and with values of convective available potential energy that seem high enough to support convective organization. These values coincide mostly with low values of convective inhibition. Vertical profiles of virtual potential temperature show little variability between soundings on a particular day, but the system means from day to day show a slight warming. In contrast, vertical profiles of pseudo-equivalent potential temperature, ?e, show much more variability between soundings on a particular day on account of the variability in moisture. In all systems, there was is a tendency for the lower troposphere to moisten, but in the non-developing system, the troposphere became progressively drier in the height range between approximately 2 and 9 km during the five days of observations. In the developing systems, the troposphere moistened. The most prominent difference between the non-developing system and the two developing systems was the much larger reduction of ?e between the surface and a height of 3 km, typically 25 K in the non-developing system, compared with only 17 K in the developing systems. Conventional wisdom would suggest that, for this reason, the convective downdraughts would be stronger in the non-developing system and would thereby act to suppress the development. Here we propose an alternative hypothesis in which the drier air weakens the convective updraughts and thereby the convective amplification of absolute vorticity necessary for development.

AB Nonuniformity in charge transport properties is a limiting factor in energy resolution of radiation detectors. In this paper, we investigate variations in the low temperature ambipolar diffusion length and the mobility-lifetime (mu tau) product in bulk doped TlBr using cathodoluminescence (CL) and transport imaging. One TlBr crystal was doped with sodium (Na), aluminum (Al), and silver (Ag). A second TlBr crystal was doped with copper (Cu), iron (Fe), and zinc (Zn). We report the first low temperature high resolution CL spectroscopy and mapping in bulk doped TlBr, showing spatial variation in recombination luminescence on a scale of similar to 10 mu m. Transport imaging is applied to quantify these variations in TlBr at 5 K. Ambipolar diffusion lengths and mu tau products, dominated by the transport of holes, are mapped across a 40 mu m segment of TlBr at a resolution of 2 mu m. Ambipolar diffusion lengths are found to vary between 4.6 mu m and 11.2 mu m, on a spatial scale comparable to the variation observed in the CL map.

AB Long-term passive acoustic monitoring of marine mammals on navy ranges provides the opportunity to better understand the potential impact of sonar on populations. The navy range in Tongue of the Ocean (TOTO), Bahamas contains extensive hydrophone arrays, potentially allowing estimation of the density of deep diving, vocally active species such as the sperm whale (Physeter macrocephalus). Previous visual surveys in TOTO have been of limited spatiotemporal coverage and resulted in only sporadic sightings of sperm whales, whereas passive acoustic observations suggest the species is present year round. However, until now the means of acoustically determining the specific number of individuals in each cluster has been limited. We used recently developed algorithms to identify the number of echolocating whales present during a 42 d study period. We screened a 297 h acoustic data set to determine the proportion of time animals were present; fifty 10 min samples during presence were analyzed to estimate the number of individuals vocalizing during each sample. These counts were combined with an independent estimate of the proportion of 10 min periods when tagged animals vocalize. The estimated average density was 0.16 whales/1,000 km2 (CV 27%; 95% CI 0.0950.264). The method is potentially applicable to other areas containing dense hydrophone arrays.

ID DIFFERENTIAL EVOLUTION; NONLINEAR MODELS; TIME-SERIES; IDENTIFICATION
AB A method for estimating model parameters based on chaotic system response data is described. This estimation problem is made challenging by sensitive dependence to initial conditions. The standard maximum likelihood estimation method is practically infeasible due to the non-smooth nature of the likelihood function. We bypass the problem by introducing an alternative, smoother function that admits a better-defined maximum and show that the parameters that maximize this new function are asymptotically equivalent to maximum likelihood estimates. We use simulations to explore the influence of noise and available data on model Duffing and Lorenz oscillators. We then apply the approach to experimental data from a chaotic Duffing system. Our method does not require estimation of initial conditions and parameter estimates may be obtained even when system dynamics have been estimated from a delay embedding.

AB Psychologists are ethically obligated to ensure their own competence. When problems of professional competence occur, psychologists must take appropriate steps to regain competence while protecting those they serve. Yet conceptualizations of the competence obligation are thoroughly intertwined with Western ideals of individualism and a model of the person as self-contained, self-controlled, and perpetually rational. Research in health care, education, and multicultural and social psychology raise serious doubts about psychologists' capacity for consistently accurate self-assessments of competence. To address this problem, the authors advocate that education, training, professional ethics standards, and credentialing criteria be infused with a robust communitarian ethos and a culturally pervasive ethic of care. The authors propose a shift in discourse about competence to incorporate both competent individuals and competent communities.

TI An Improved Empirical Model for Radar Sea Clutter Reflectivity
SO IEEE TRANSACTIONS ON AEROSPACE AND ELECTRONIC SYSTEMS
LA English
DT Article
AB A fundamental characteristic of radar sea clutter, important for radar performance evaluations, is its apparent reflectivity defined as sigma degrees (m(2)/m(2)). "Apparent" is used as a reminder that any measurement of sea clutter reflectivity includes the effects of propagation and shadowing close to the sea surface. Sea clutter reflectivity depends on many factors, including sea state, wind velocity, grazing angle, polarization, and radar frequency. An empirical sea clutter model proposed by Horst, et al. (1978), the so-called GIT model, has found widespread acceptance in the radar community.
However, this model does not always agree with what is the most complete experimental database of sea clutter reflectivity available to the radar systems engineer. The 1991 edition of F. E. Nathanson's book provides seven tables of measured sea clutter reflectivity data summarized from approximately 60 sources. The large deviation between the GIT model and this database, in particular at lower sea states, has prompted NRL to develop an improved model for sea clutter reflectivity based on these tables. The model is a function of radar frequency, polarization, sea state, and grazing angle. The functional form of this empirical model was chosen such that the average absolute deviation (in dB) between the model and the experimental data was minimized.

AB We consider a general swarm model of self-propelling agents interacting through a pairwise potential in the presence of noise and communication time delay. Previous work has shown that a communication time delay in the swarm induces a pattern bifurcation that depends on the size of the coupling amplitude. We extend these results by completely unfolding the bifurcation structure of the mean field approximation. Our analysis reveals a direct correspondence between the different dynamical behaviors found in different regions of the coupling-time delay plane with the different classes of simulated coherent swarm patterns. We derive the spatiotemporal scales of the swarm structures, as well as demonstrate how the complicated interplay of coupling strength, time delay, noise intensity, and choice of initial conditions can affect the swarm. In particular, our studies show that for sufficiently large values of the coupling strength and/or the time delay, there is a noise intensity threshold that forces a transition of the swarm from a misaligned state into an aligned state. We show that this alignment transition exhibits hysteresis when the noise intensity is taken to be time dependent.

AB Purpose To evaluate the incidence of tendon rupture after nonoperative and operative management of distal radius fractures, report clinical outcomes after tendon repair or transfer, and examine volar plate and dorsal screw prominence as a predictor of tendon rupture.
Methods We performed a retrospective chart review on patients treated for tendon rupture after distal radius fracture. We evaluated active range of motion, Disabilities of Arm, Shoulder, and Hand score, grip strength, and pain score, and performed radiographic evaluation of volar plate and dorsal screw prominence in both the study group and a matched control group.
Results There were 6 tendon ruptures in 1,359 patients (0.4%) treated nonoperatively and 8 tendon ruptures in 999 patients (0.8%) treated with volar plate fixation. At the time of final follow-up, regardless of treatment, we noted that patients had minimal pain and excellent motion and grip strength. Mean Disabilities of the Shoulder, Arm, and Hand scores were 6 for patients treated nonoperatively and 4 for those treated with volar plating.
Conclusions We were unable to verify volar plate or dorsal screw prominence as independent risk factors for tendon rupture after distal radius fractures. However, we recommend continued follow-up and plate removal for symptomatic patients who have volar plate prominence or dorsal screw prominence. In the event of tendon rupture, we report excellent clinical outcomes after tendon repair or tendon transfer. (J Hand Surg 2012;37A:2035-2040.

AB Purpose Distal biceps rupture is a relatively uncommon injury. Surgical repair is performed in patients who seek increased flexion and supination strength over that which results from nonoperative treatment. The purpose of this study was to evaluate complications associated with surgical repair of the distal biceps tendon in a large series of patients.
Methods We retrospectively reviewed 198 consecutive patients with distal biceps ruptures treated with surgical repair, and evaluated time from injury to repair, surgical technique, and complications.
Results A total of 72 patients (36%) developed complications; 6 patients underwent additional surgery. Minor complications included lateral antebrachial cutaneous nerve paresthesia (26%), radial sensory nerve paresthesia (6%), and superficial infection (2%). Major complications included posterior interosseous nerve injury (4%), symptomatic heterotropic ossification (3%), and re-rupture (2%).
Conclusions Minor complications were common after distal biceps tendon repair; however, most were sensory nerve injuries that resolved with time. Major complications were infrequent, and few patients required revision surgery. Complications were more common after distal biceps tendon repair performed more than 28 days after rupture.

AB Navies in the age of sail required artisans familiar with the working of a sailing vessel as well as a warship's operations. The years 1797 to 1812 were formative for the body of skilled petty officers on whom commissioned and warrant officers relied to turn their armed ships into effective instruments of warfare. This essay provides an overview of the early U.S. Navy's process of recruiting and training petty officers, how the character of subordination and discipline was negotiated between commissioned and lesser officers, and the petty officers' life aboard ship in the era of the War of 1812.

AB It proved difficult for Britain's Royal Navy to fight the War of 1812 while already at war with France. This ongoing conflict had lasted for nearly two decades and had left Britain with few reserves. Moreover, war with America necessitated a massive westward shift in naval deployments even while the European war intensified with Napoleon's invasion of Russia and the expansion of Wellington's Peninsular Campaign. The following article analyzes how the Royal Navy balanced operations between Napoleon's Empire and the United States with an emphasis on 1812 and 1813.

ID BRAIN-TUMORS; GLIOMA; CHILDREN
AB In the United States, the 5-year survival rate for patients of all ages with all types of brain tumors is approximately 20%, with the scale skewed toward even poorer survival in patients with gliomas. Although surgery and radiotherapy are primary treatment options, surgery is rarely curative and radiotherapy has had little impact on overall survival. Predominantly studied in adults with advanced high-grade gliomas, photodynamic therapy (PDT) represents a paradigmatic shift in the treatment of brain tumors. With no clear standard of care for brain tumors, PDT may emerge as a potential alternative, although challenges regarding its clinical use remain and studies confirming its promise are necessary.

ID SOLAR ERUPTION; ACCELERATION; FLOWS; LOOPS
AB We investigate the initiation and formation of Coronal Mass Ejections (CMEs) via a detailed two-viewpoint analysis of low corona observations of a relatively fast CME acquired by the SECCHI instruments aboard the STEREO mission. The event which occurred on 2 January 2008, was chosen because of several unique characteristics. It shows upward motions for at least four hours before the flare peak. Its speed and acceleration profiles exhibit a number of inflections which seem to have a direct counterpart in the GOES light curves. We detect and measure, in 3D, loops that collapse toward the erupting channel while the CME is increasing in size and accelerates. We suggest that these collapsing loops are our first evidence of magnetic evacuation behind the forming CME flux rope. We report the detection of a hot structure which becomes the core of the white light CME. We observe and measure unidirectional flows along the erupting filament channel which may be associated with the eruption process. Finally, we compare these observations to the predictions from the standard flare-CME model and find a very satisfactory agreement. We conclude that the standard flare-CME concept is a reliable representation of the initial stages of CMEs and that multi-viewpoint, high cadence EUV observations can be extremely useful in understanding the formation of CMEs.

ID SMALL-ANGLE APPROXIMATION; IMAGING-SYSTEMS; BEAM; PARTICLES
AB The point spread and modulation transfer functions for natural waters are derived using the small-angle approximation to radiative transfer theory. The functional forms are expanded into a summation of terms that represent each order-of-scattering contribution to the total. The beam spread function is shown to be a product of an angle function that depends only on the phase function of the medium and a weighting factor that depends only on the optical properties and depth. The modulation transfer function is similarly shown as a product of a function depending only on the spatial frequency and a weighting function. These results are compared with Monte Carlo calculations using two different phase functions, with excellent agreement. The results suggest the small-angle approximation to be valid over a much larger angular range than previously thought.

AB Objective To assess anthropometric changes from birth to hospital discharge in infants born preterm and compare with a reference birth cohort of infants born full-term.
Study design Retrospective chart review was conducted of 501 preterm and 1423 full-term infants. We evaluated birth and hospital discharge weight, length, and waist circumference (WC). WC/length ratio (WLR), ponderal index, and body mass index (BMI) were calculated. Preterm infants were categorized into quartiles (Q1-4) based on birth weight (BW).
Results At birth mean length, WC, WLR, BMI, and ponderal index were all significantly less for preterm infants in the lowest BW quartile (Q1) than preterm infants in higher BW quartiles or full-term infants. Although their weight, length, and BMI remained significantly less at discharge, preterm infants in Q1 had a disproportionate increase in WLR and ponderal index such that at discharge their WLR and ponderal index were greater than infants in Q2-3 and comparable with infants in Q4 and full-term infants. Discharge WLR and ponderal index in Q1 were significantly higher with decreasing postmenstrual age at birth.
Conclusions Preterm infants of a lower birth postmenstrual age have disproportionate increases in WLR and ponderal index that are suggestive of increased visceral and total adiposity. (J Pediatr 2012;161:735-41).

AB Objective: The objective was to estimate the self-reported prevalence of domestic violence in a pregnant military population presenting for emergency care, and to determine the acceptability of domestic violence screening.
Study Design: A prospective observational survey of patients presenting for obstetric emergency care. Women were anonymously screened for domestic violence using the Abuse Assessment Screen.
Result: A total of 499 surveys were distributed, with 26 duplicate surveys. After excluding the 12 blank surveys, a total of 461 surveys were included in the final analysis. The lifetime prevalence of domestic violence (including physical, emotional and sexual abuse) was 22.6% (95% CI = 19.0 to 26.4) with 4.1% (95% CI = 2.3-6.0) of women reporting physical abuse in the past year and 2.8% (95% CI = 1.3-4.3) reporting abuse since becoming pregnant. The majority of women 91.8% (95% CI = 88.7-94.2) were not offended by domestic violence screening and 88.8% (95% CI = 82.0-88.9) felt that patients should be routinely screened.
Conclusion: The self-reported prevalence of domestic violence in a pregnant military population presenting for emergency care was 22.6%. Most women are not offended by domestic violence screening and support routine screening. Journal of Perinatology (2012) 32, 763-769; doi:10.1038/jp.2011.188; published online 2 February 2012

AB Congenital aortic aneurysms are a rare, life-threatening disorder that present complex treatment challenges. The authors describe a congenital thoracic aortic aneurysm treated by endovascular means with stent-assisted coil deployment. Because of rapid in utero aneurysm growth and cardiac dysfunction, a 2.6-kg male was delivered expeditiously by Cesarean section at 35 2/7 weeks' gestation. On day of life 1, bilateral femoral arterial access was used to deliver a balloon-expandable stent across the wide-necked aneurysm. Microcoil embolization of the aneurysm via a prepositioned microcatheter was then performed. The child had an uncomplicated hospital course and is asymptomatic 5 months later, with complete aneurysm thrombosis.

ID MICROCANTILEVER ARRAYS; PERFORMANCE; DESIGN
AB In this Letter, we describe the fabrication of an array of bimaterial detectors for infrared (IR) imaging that utilize SiO2 as a structural material. All the substrate material underneath the active area of each detector element was removed. Each detector element incorporates an optical resonant cavity layer in the IR-absorbing region of the sensing element. The simplified microfabrication process requires only four photolithographic steps with no wet etching or sacrificial layers. The thermomechanical deflection sensitivity was 7.9 x 10(-3) rad/K, which corresponds to a noise equivalent temperature difference (NETD) of 2.9 mK. In the present work, the array was used to capture IR images while operating at room temperature and atmospheric pressure without the need for vacuum packaging. The average measured NETD of our IR detector system was approximately 200 mK, but some sensing elements exhibited an NETD of 50 mK. (C) 2012 Optical Society of America

An X-ray crystallographic analysis confirms the structure of this material, as well as displays intramolecular hydrogen bonding. A gas pycnometry density for this material was measured to be 1.79 g?cm-3. The heat of formation of this material was also measured. These data, along with the molecular formula were used as inputs to calculate the detonation velocity and detonation pressure using the Cheetah thermochemical code. The sensitivity of this material towards impact, spark and friction was also measured, as well as its vacuum thermal stability. The 3-azido derivative 2 was also prepared and its properties are described as well. The above data show that (ANTA-NQ) may be a high performing material with low sensitivity and good thermal stability.

AB Scholars of corporate social responsibility (CSR), which refers to the responsibilities of a firm to society in four domains: economic, legal, ethical, and discretionary, have typically excluded defense firms from their research, mainly on ideological grounds. This study challenges these assumptions and measures the CSR orientations of managers of defense firms. The findings reveal the orientations of defense firm managers to be consistent with those of other corporate populations, though the highly regulated environment of defense contracting causes some differences. The findings help to redeem the social standing of defense firms, and by implication, their employees and the military members who use their products, from unwarranted antimilitary biases.

AB We use dense seismic network recordings of accurately located surface explosions in northern Utah to shed light on the propagation of infrasound through the stratosphere. The data clearly show propagation of infrasound downwind from the source, as expected. The data also clearly show the penetration of infrasound into geometric shadow zones near the source and the spread of infrasound to a distance of 800 km from the source. The spread of infrasound both toward and away from the source is not predicted by applying either ray theory or the full-wave finite-difference technique to smooth ground-to-space (G2S) models. The mismatch between synthetics and data suggest a missing component in these models, possibly a small-scale gravity-wave structure. Comparison of the network recordings of approximately 1500 infrasound signals with travel-time predictions based on rays shows no significant average bias in the travel times. On average, recorded signals arrived 1 s earlier than predictions. Travel-time residuals are normally distributed about the mean with a standard deviation of 15 s. The small bias of the travel-time predictions indicates that despite the fact that small-scale structure is averaged out of commonly used G2S models, the large-scale structure of the atmosphere is accurately represented. The scatter of travel-time residuals is suggestive of small-scale structure missing from the models that we used to make the predictions, but firm conclusions would require a more in-depth study.

AB Minimizing scar size, width, and contour of elevation is a common goal for the facial plastic surgeon. Various standard techniques are employed to reduce tension and enhance the rapid and uneventful healing of incisions. In some cases, these routine measures are not judged to be adequate, and additional intraoperative and postsurgical measures are employed to control the body's innate healing processes. Mitomycin C and self-drying silicone gel have been particularity useful in our practice.

AB 1. Natural sunlight gradients occur on multiple scales in space and time. However, the direct (via habitat) and indirect effects (via plant quality) of light environment are often confounded, obscuring the relative importance of each in influencing herbivore responses. 2. Potted saplings of Quercus alba (white oak, Fagaceae) were grown in either full sun or full shade from budburst to leaf hardening to manipulate leaf phenotype (creating sun or shade leaves), then placed in either sunny light gaps or adjacent shaded forest understorey habitats. This two-way factorial design isolated the effects of sunlight level during leaf expansion from light environment late in the growing season on leaf phenology, leaf traits associated with host plant quality for herbivores, herbivore density and folivory. 3. Sunlight level during leaf expansion and hardening had strong and persistent effects on Q.alba leaf phenology and phenotype. Shade saplings had later budburst (c. 4days), and fewer but larger leaves, resulting in greater total leaf area compared with sun leaf saplings. Shade leaves had higher water content, specific leaf area and nitrogen content, and lower toughness, carbon content, C/N ratios and concentrations of hydrolysable and condensed tannins than sun leaves. 4. Despite the apparent higher quality of shade leaves, forest habitat better predicted damage by folivores than leaf type, suggesting that the direct effects of light environment predominate for herbivory. Potted saplings of both leaf types placed in the shaded understorey suffered almost two times more folivory, on average, than saplings in sunny light gaps, despite more than three times higher mid-season herbivore density on sun leaf saplings relative to shade leaf saplings. 5. Taken together, these results suggest that both leaf phenotype and forest habitat, two factors frequently confounded in nature, have significant but distinct effects on leaf quality and herbivory. These findings have implications for plantherbivore interactions following disturbances such as treefalls, when shade leaves may be present in sunny habitats, and may help explain patterns of herbivory in understorey plants with early leaf flushing phenology relative to the canopy, when sun leaves are present in the shaded understorey.

AB We report direct radio-frequency (RF) and millimeter-wave detection of epitaxial graphene field-effect transistors (FETs) up to 110 GHz with no dc biases applied, leveraging the nonlinearity of the channel resistance. A linear dynamic range of > 40 dB was measured, providing at least 20-dB greater linear dynamic range compared to conventional CMOS detectors at transistor level. The measured noise power of the graphene FETs was similar to 7.5 x 10(-18) V-2/Hz at zero bias and without 1/f noise. At a 50-Omega load, measured detection responsivity was 71 V/W at 2 GHz to 33 V/W at 110 GHz. The noise-equivalent power at 110 GHz was estimated to be similar to 80 pW/Hz(0.5). For the first time, we demonstrated graphene FETs as zero-bias ultrawideband direct RF detectors with comparable or better performance than state-of-the-art FET-based detectors without dc biases applied.

AB Introduction: Explosions have caused a greater percentage of injuries in Iraq and Afghanistan than in any other large-scale conflict. Improvements in body armour and field medical care have improved survival and changed the injury profile of service personnel. This study's objective was to determine the nature, body region, and severity of injuries caused by an explosion episode in male service personnel.
Materials and methods: A descriptive analysis was conducted of 4623 combat explosion episodes in Iraq between March 2004 and December 2007. The Barell matrix was used to describe the nature and body regions of injuries due to a combat explosion.
Results: A total of 17,637 International Classification of Diseases, Ninth Revision (ICD-9) codes were assigned to the 4623 explosion episodes, with an average of 3.8 ICD-9 codes per episode. The most frequent single injury type was a mild traumatic brain injury (TBI; 10.8%). Other frequent injuries were open wounds in the lower extremity (8.8%) and open wounds of the face (8.2%), which includes tympanic membrane rupture. The extremities were the body regions most often injured (41.3%), followed by head and neck (37.4%) and torso (8.8%).
Conclusion: The results of this study support previous observations of TBI as a pre-eminent injury of the wars in Iraq and Afghanistan, with mild TBI as the most common single injury in this large cohort of explosion episodes. The extremities had the highest frequency of injuries for any one body region. The majority of the explosion episodes resulted in more than one injury, and the variety of injuries across nearly every body region and injury type suggests a complex nature of explosion injuries. Understanding the constellation of injuries commonly caused by explosions will assist in the mitigation, treatment, and rehabilitation of the effects of these injuries. (c) 2012 Elsevier Ltd.

AB Introduction: Improvised explosive devices (IEDs) are the defining mechanism of injury during Operation Enduring Freedom. This is a retrospective analysis of initialmanagement for IED blast injuries presenting with bilateral, traumatic, lower-extremity (LE) amputations with and without pelvic and perineal involvement.
Methods: A database of trauma admissions presenting to a North Atlantic Treaty Organization (NATO) Role 3 combat hospital in southern Afghanistan over a 7-month period was created to evaluate the care of this particular injury pattern. Patients were included if they were received from point of injury with at least bilateral traumatic LE amputations and had vital signs with initial resuscitation efforts.
Results: Thirty-two presented with double LE amputations (36%) and nine with triple amputations (10%). After excluding 10 patients who failed to meet the inclusion criteria, 22 patients were analysed. The mean age was 29 years, and the average ISS and admission haemoglobin were 22 and 11.3 mg l (1), respectively. Patients received an average of 54 units of blood products and underwent 1.6 operations with a mean operative time of 142.5 min. The pattern of injury was associated with an increase in the total blood products required for resuscitation (pelvis n = 12, p = 0.028, gastrointestinal tract (GI) n = 14, p = 0.02, perineal n = 15, p = 0.036). There was no relationship between ISS or admission haemoglobin and the need for massive transfusion. Low Glasgow Coma Scale (GCS) was associated with increased 30-day mortality. Hollow viscus injury and operative hemipelvectomy were also associated with mortality.
Conclusions: Early 30-day follow-up demonstrated that IED injuries with bilateral LE amputations with and without pelvic and perineal involvement are survivable injuries. Standard measures of injury and predictors of survival bore little relationship to observed outcomes and may need to be re-evaluated. Long-term follow-up is needed to assess the extent of functional recovery and overall morbidity and mortality. Published by Elsevier Ltd.

Sailors and Marines newly diagnosed as HIV positive from 2005 to 2010 were invited to participate in an online survey. A structured questionnaire elicited risk information about the 3-year period before HIV diagnosis. Respondents reported engaging commonly in same sex sexual activity, having concurrent partners, and poor condom use for anal sex. In this first post-DADT repeal report of self-reported behaviors, male-to-male sexual contact was a much more common mode of infection than previously reported. Several opportunities for primary prevention messaging now possible after DADT repeal are evident.

AB We report Fermi Large Area Telescope (LAT) observations of the radio-loud active galactic nucleus SBS 0846+513 (z = 0.5835), optically classified as a narrow-line Seyfert 1 galaxy, together with new and archival radio-to-X-ray data. The source was not active at ?-ray energies during the first two years of Fermi operation. A significant increase in activity was observed during 2010 October2011 August. In particular, a strong ?-ray flare was observed in 2011 June reaching an isotropic ?-ray luminosity (0.1300?GeV) of 1.0 X 1048?erg?s-1, comparable to that of the brightest flat spectrum radio quasars, and showing spectral evolution in ? rays. An apparent superluminal velocity of (8.2 +/- 1.5)c in the jet was inferred from 2011 to 2012 Very Long Baseline Array (VLBA) images, suggesting the presence of a highly relativistic jet. Both the power released by this object during the flaring activity and the apparent superluminal velocity are strong indications of the presence of a relativistic jet as powerful as those of blazars. In addition, variability and spectral properties in radio and ?-ray bands indicate blazar-like behaviour, suggesting that, except for some distinct optical characteristics, SBS 0846+513 could be considered as a young blazar at the low end of the blazar's black hole mass distribution.

AB BACKGROUND: One of the most important decisions in the treatment of osteoarticular infections is the time at which parenteral therapy can be changed to oral therapy. C-reactive protein (CRP) is an acute inflammatory indicator with a half-life of 19 hours and thus can be helpful in assessing the adequacy of therapy for bacterial infections. At our institution, a combination of CRP and clinical findings is used to determine the transition to oral therapy.
METHODS: A search of 8 years of electronic records identified children with osteoarticular infections. Only children with culture-positive acute bacterial arthritis (ABA) or acute bacterial osteomyelitis (ABO) were studied further. A primary chart review of demographic and clinical data was conducted, and a secondary chart review of complicated outcomes was performed.
RESULTS: Of 194 total patients, complicated outcomes occurred in 40, of which 35 were prolonged therapy. Only 1 microbiologic failure occurred, presumably due to a retained intra-articular fragment of infected bone. CRP was highest initially among patients with simultaneous ABO + ABA and among those with complicated outcomes, and was lower at the transition to oral therapy in the complicated outcome group (1.5 vs 2.1 mg/dL; P = .012).
CONCLUSIONS: The combination of clinical findings and CRP is a useful tool to transition children with osteoarticular infections to oral therapy. Complicated outcomes were associated with higher early CRP at diagnosis and lower CRP at the end of parenteral therapy, suggesting that clinicians were more conservative with prolonged initial parenteral therapy in this group.

AB BACKGROUND: Current quantitative methods for airborne dichlorodiphenyltrichloroethane (DDT) require collection and extraction times of = 12 h. The aim of this study was to develop a method for quantifying airborne DDT with a short (<4 h) collection and analysis time. RESULTS: Precision [relative standard deviation (RSD)] for each calibration point (0.89.0), linearity (R2 = 0.99) and apparent recovery (R' = 96.5%) were determined from thermal desorption (TD) gas chromatographymass spectrometry (GC-MS) analyses of Tenax-TA-packed sampling tubes spiked with 1250 ng of DDT. Recovery of 13C-labeled 4,4'-DDT from tubes spiked before and after air sampling was 97.3 and 90.3% respectively. DDT was detected and quantified in 13 L samples of air collected during 10180 min sampling events. A significant difference was observed in DDT air concentration between 28 and 33 degrees C during microchamber studies. CONCLUSIONS: The results demonstrate that the TD GC-MS method developed in this study is precise, reproducible and linear over the span of 1250 ng of DDT spiked onto TD tubes. By avoiding dilution of the sample, the method described allows the measurement of DDT vapor concentrations during short sampling periods (10180 min) relevant to mosquito behavior studies.

AB Solar energetic particle (SEP) events reaching rigidities > 1 GV are observed at 1 AU as ground-level events (GLEs). They are considered to be extreme cases of gradual SEP events, produced by shocks driven by wide and fast CMEs that are usually associated with long-duration (> 1 hour) soft X-ray (SXR) flares. However, some large gradual SEP events, including GLEs, are associated with flares of short-duration (< 1 hour) timescales comparable to those of flares seen with impulsive, low-energy SEP events with enhanced charge states, heavy-element abundances, and e/p ratios. The association of some GLEs with short-duration SXR events challenges us to understand the GLE event-to-event variation with SXR durations and whether it truly reflects the nature of the particle acceleration processes or simply the characteristics of the solar regions from which large, fast CMEs arise. We examine statistically the associated flare, active region (AR), and CME characteristics of similar to 40 GLEs observed since 1976 to determine how the GLE e/p and Fe/O ratios, each measured in two energy ranges, depend on those characteristics. The abundance ratios trend weakly to lower, more coronal, and less scattered values with increasing flare timescales, thermal and nonthermal peak fluxes, and measures of source AR sizes. These results and the wide range of solar longitude connections for GLEs with high abundance ratios argue against a significant role for flare effects in the GLEs. We suggest that GLE SEPs are accelerated predominately in CME-driven shocks and that a coupling of flare size and timescales with CME properties could explain the SEP abundance correlations with flare properties.

AB We present calculations of absorption spectra arising from molecular vibrations at THz frequencies for molecular clusters of the explosive HMX using density functional theory (DFT). The features of these spectra can be shown to follow from the coupling of vibrational modes. In particular, the coupling among ground-state vibrational modes provides a reasonable molecular-level interpretation of spectral features associated with the vibrational modes of molecular clusters. THz excitation from the ground state is associated with frequencies that characteristically perturb molecular electronic states, in contrast to frequencies, which are usually substantially above the mid-infrared (mid-IR) range, that can induce appreciable electronic-state transition. Owing to this characteristic of THz excitation, one is able to make a direct association between local oscillations about ground-state minima of molecules, either isolated or comprising a cluster, and THz absorption spectra. The DFT software program GAUSSIAN was used for the calculations of the absorption spectra presented here.

VIRUS
AB Background. The US Centers for Disease Control and Prevention estimates 20.9 million norovirus infections annually in the United States. Although the acute disease burden is sizeable, emerging data suggest norovirus may be associated with chronic gastrointestinal problems. We identified known outbreaks in US military recruits and used the Defense Medical Encounter Database (DMED) to identify the risk of new onset functional gastrointestinal disorders (FGD) and gastroesophageal reflux disease (GERD).
Methods. Subjects reporting for care of acute gastroenteritis (AGE) at a military treatment clinic during 3 known norovirus outbreaks were identified. Each AGE subject was matched with up to 4 subjects with unrelated medical encounters. Medical encounter data were analyzed for the duration of military service time (or a minimum of 1 year) to assess for incident FGD or GERD. Relative risks were calculated using regression models.
Results. We identified 1718 subjects from 3 outbreaks. After controlling for important demographic covariates, the incidence of constipation, dyspepsia, and GERD was approximately 1.5-old higher (P < .01) in AGE-exposed subjects than matched subjects. We also noted variability in outcome incidence across outbreaks.
Conclusions. It appears that the risk of dyspepsia, constipation, and GERD are higher among those who have AGE during a confirmed norovirus outbreak. Although these findings need confirmation, they suggest that dysmotility may result subsequent to these infections. If confirmed, the costs and morbidity associated with the chronic consequences of norovirus should be considered.

AB Prior research on the labor market success of secondary vocational education has produced mixed results, with several studies finding wage gains only for individuals who work in training-related occupations. We contribute to this debate by focusing on a single occupation and organization and by comparing the careers of employees with and without occupation-related training in high school. We use longitudinal data on the careers of military recruits who completed high school Junior Reserve Officers' Training Corps (JROTC), a military science program that has features of a vocational training and school-to-work program. We find that the occupation-specific training received via JROTC reduces early turnover and improves long-run job stability for those who choose military jobs, suggesting that an important effect of vocational training is to improve job match quality. We also. find that promotion rates for vocational graduates are similar to their peers, suggesting that vocational education in general works by improving occupational sorting.

AB The electrochemical behavior of magnesium perchlorate in ionic liquids is characterized using Co3O4 as the working electrode and Mg foil as the anode material. The cations of the ionic liquids were 1,2-dimethy1-3-R-imidazolium with R = butyl (MMBI) or octyl (MMOI), and the anion was bis(trifluoromethanesulfonyl)imide (TFSI). The TFSI ionic liquids exhibited large electrochemical windows, with MMOITFSI possessing an electrochemical window of 5 V. Ionic conductivity studies indicated a higher ionic conductivity of 3.67 ms/cm for 1.0 M Mg(ClO4)(2) in MMBITFSI when compared to 2.16 mS/cm for 1.0 M Mg(ClO4)(2). MMOITFSI was selected as the electrolyte for the electrochemical characterizations of Co3O4, due to its larger electrochemical window and its inability to intercalate, and therefore degrade, graphitic material added to the Co3O4 electrode. Electrochemical results indicated that the maximum attainable value for x in MgxCo3O4 was 0.33, with an initial capacity of only 78 mAh/g. X-ray diffraction studies of the Mg intercalated Co3O4 indicated a 20% expansion of the unit cell and a decrease in the symmetry of the metal oxide from cubic to orthorhombic symmetry. Charge/discharge experiments at a C/3 rate were performed vs. Mg metal. Results indicated that after 10 cycles, the capacity decreased linearly with cycling, most likely due to the inability to deintercalate the more strongly interacting Mg++. (C) 2012 Elsevier Ltd.

AB The solar outer atmosphere is an extremely dynamic environment characterized by the continuous interplay between the plasma and the magnetic field that generates and permeates it. Such interactions play a fundamental role in hugely diverse astrophysical systems, but occur at scales that cannot be studied outside the solar system. Understanding this complex system requires concerted, simultaneous solar observations from the visible to the vacuum ultraviolet (VUV) and soft X-rays, at high spatial resolution (between 0.1'' and 0.3''), at high temporal resolution (on the order of 10 s, i.e., the time scale of chromospheric dynamics), with a wide temperature coverage (0.01 MK to 20 MK, from the chromosphere to the flaring corona), and the capability of measuring magnetic fields through spectropolarimetry at visible and near-infrared wavelengths. Simultaneous spectroscopic measurements sampling the entire temperature range are particularly important. These requirements are fulfilled by the Japanese Solar-C mission (Plan B), composed of a spacecraft in a geosynchronous orbit with a payload providing a significant improvement of imaging and spectropolarimetric capabilities in the UV, visible, and near-infrared with respect to what is available today and foreseen in the near future. The Large European Module for solar Ultraviolet Research (LEMUR), described in this paper, is a large VUV telescope feeding a scientific payload of high-resolution imaging spectrographs and cameras. LEMUR consists of two major components: a VUV solar telescope with a 30 cm diameter mirror and a focal length of 3.6 m, and a focal-plane package composed of VUV spectrometers covering six carefully chosen wavelength ranges between 170 and 1270 . The LEMUR slit covers 280'' on the Sun with 0.14'' per pixel sampling. In addition, LEMUR is capable of measuring mass flows velocities (line shifts) down to 2 km s (-aEuro parts per thousand 1) or better. LEMUR has been proposed to ESA as the European contribution to the Solar C mission.

AB High-time-resolution X-ray observations of compact objects provide direct access to strong-field gravity, to the equation of state of ultradense matter and to black hole masses and spins. A 10 m(2)-class instrument in combination with good spectral resolution is required to exploit the relevant diagnostics and answer two of the fundamental questions of the European Space Agency (ESA) Cosmic Vision Theme "Matter under extreme conditions", namely: does matter orbiting close to the event horizon follow the predictions of general relativity? What is the equation of state of matter in neutron stars? The Large Observatory For X-ray Timing (LOFT), selected by ESA as one of the four Cosmic Vision M3 candidate missions to undergo an assessment phase, will revolutionise the study of collapsed objects in our galaxy and of the brightest supermassive black holes in active galactic nuclei. Thanks to an innovative design and the development of large-area monolithic silicon drift detectors, the Large Area Detector (LAD) on board LOFT will achieve an effective area of similar to 12 m(2) (more than an order of magnitude larger than any spaceborne predecessor) in the 2-30 keV range (up to 50 keV in expanded mode), yet still fits a conventional platform and small/medium-class launcher. With this large area and a spectral resolution of < 260 eV, LOFT will yield unprecedented information on strongly curved spacetimes and matter under extreme conditions of pressure and magnetic field strength.

headphones
SO INTERNATIONAL JOURNAL OF AUDIOLOGY

DE Hearing protection; HPD; earplugs; attenuation; fit-testing;
supra-aural; circumaural; headphones; TDH
AB Objective: Supra-aural audiometric headphones are generally not recommended for use in measuring the attenuation of earplugs, because contact between the headphone and pinna and/or earplug could alter the attenuation obtained, and because of concerns of non-comparability between modes of excitation from supra-aural headphones and the sound-field procedure required by the standardized method. In this study, we compared measurements of earplug attenuation obtained under Telephonics TDH-50P supra-aural headphones with measurements obtained under circumaural headphones designed expressly for such testing. Design: The attenuation of three types of earplugs (foam, premolded quadruple-flange, and custom-molded) was measured in a repeated-measures design. Study sample: The study sample comprised 42 normal-hearing adults (21 females, 21 males). Results: With the foam earplugs, nearly all of the attenuation measurements under the supra-aural headphones fell within 10 dB of the measurements under the circumaural headphones. With the flange and custom earplugs, approximately 10% of individuals obtained spuriously high attenuation under the supra-aural headphones. Conclusions: We conclude that standard supra-aural audiometric headphones are suitable for measuring the attenuation provided by foam earplugs. However, supra-aural headphones should not be used to measure the attenuation of flange or custom-molded earplugs. The potential exists for substantial over-estimation of attenuation, especially of custom plugs.

AB Major revolts have recently erupted in parts of the Middle East with substantial international repercussions. Predicting, coping with and winning those revolts have become a grave problem for many regimes and for world powers. We propose a new model of such revolts that describes their evolution by building on the classic Lanchester theory of combat. The model accounts for the split in the population between those loyal to the regime and those favouring the rebels. We show that, contrary to classical Lanchesterian insights regarding traditional force-on-force engagements, the outcome of a revolt is independent of the initial force sizes; it only depends on the fraction of the population supporting each side and their combat effectiveness. The model's predictions are consistent with the situations currently observed in Afghanistan, Libya and Syria ( September 2011), and it points to how those situations might evolve.

AB Optimality functions define stationarity in nonlinear programming, semi-infinite optimization, and optimal control in some sense. In this paper, we consider optimality functions for stochastic programs with nonlinear, possibly nonconvex, expected value objective and constraint functions. We show that an optimality function directly relates to the difference in function values at a candidate point and a local minimizer. We construct confidence intervals for the value of the optimality function at a candidate point and, hence, provide a quantitative measure of solution quality. Based on sample average approximations, we develop an algorithm for classes of stochastic programs that include CVaR-problems and utilize optimality functions to select sample sizes.

AB Microstructures produced by isothermal hot rolling of a NiAl bronze material were evaluated by quantitative microscopy methods and parameters describing the contributions of precipitate dispersions, grain size, solute content, and dislocation density to the yield strengths of the individual constituents of microstructure were determined. Models for the strengths of the individual constituents were combined to predict the temperature dependence of the yield strength as a function of hot rolling temperature, and the prediction was found to be in good agreement with measured yield strengths. The models were applied to microstructures in a stir zone produced by multipass friction-stir processing (FSP) and, again, found to predict measured yield strengths with high accuracy. Such models may aid in assessing the role of microstructure gradients produced during FSP and other processes.

AB A nonhydrostatic, fully compressible spectral element (SE) model is evaluated in a series of two-dimensional idealized simulations. A dry formulation of the model is evaluated for a linear hydrostatic mountain-wave case, and a version with moisture is tested for a squall line. In the SE method, two setup parameters control the spatial resolution: the number of elements (h) and the polynomial order (p) of the basis functions. In this paper, the h=p parameter space is systematically explored, with the average horizontal resolution (Delta x) varying from 0.2 to 10 km in 91 simulations.
The dry experiments are evaluated using an analytic solution. The ratio of Delta x/a < 0.2, where a is the mountain half-width, is sufficient to accurately resolve the mountain wave. Accuracy. computational cost, and convergence to the analytic solution are evaluated and compared to a second-order finite-difference (FD) model. The increase in computational cost by refining the spatial resolution yields a significant accuracy gain for the SE, with only a marginal improvement for the FD model.
The squall line is evaluated across the control parameter space by assessing three integrated quantities: total precipitation accumulation, maximum vertical velocity, and maximum precipitation rate. The squall line is adequately resolved with Delta x < 2 km and p > 5. There is little variation in metrics due to the varying nodal spacing within an element at the same average Delta x. When the spatial resolution is refined, the analyzed metrics no longer converge. The nonlinear nature of moist convection is responsible for this resolution dependence as a result of localized buoyancy sources, evident in the vertical velocity spectrum.

TI Impact of Physics Representations in the HWRFX on Simulated Hurricane

AB A series of idealized experiments with the NOAA Experimental Hurricane Weather Research and Forecasting Model (HWRFX) are performed to examine the sensitivity of idealized tropical cyclone (TC) intensification to various parameterization schemes of the boundary layer (BL), subgrid convection, cloud microphysics, and radiation. Results from all the experiments are compared in terms of the maximum surface 10-m wind (VMAX) and minimum sea level pressure (PMIN)-operational metrics of TC intensity-as well as the azimuthally averaged temporal and spatial structure of the tangential wind and its material acceleration.
The conventional metrics of TC intensity (VMAX and PMIN) are found to be insufficient to reveal the sensitivity of the simulated TC to variations in model physics. Comparisons of the sensitivity runs indicate that (i) different boundary layer physics parameterization schemes for vertical subgrid turbulence mixing lead to differences not only in the intensity evolution in terms of VMAX and PMIN, but also in the structural characteristics of the simulated tropical cyclone; (ii) the surface drag coefficient is a key parameter that controls the VMAX PMIN relationship near the surface; and (iii) different microphysics and subgrid convection parameterization schemes, because of their different realizations of diabatic heating distribution, lead to significant variations in the vortex structure.
The quantitative aspects of these results indicate that the current uncertainties in the BL mixing, surface drag, and microphysics parameterization schemes have comparable impacts on the intensity and structure of simulated TCs. The results also indicate that there is a need to include structural parameters in the HWRFX evaluation.

TI DISCOVERY OF AN UNUSUALLY RED L-TYPE BROWN DWARF

AB We report the discovery of an unusually red brown dwarf found in a search for high proper motion objects using WISE and 2MASS data. WISEP J004701.06+680352.1 is moving at 0 ''.44 yr(-1) and lies relatively close to the Galactic plane (b = 5 degrees.2). Near-infrared photometry and spectroscopy reveals that this is one of the reddest (2MASS J - K-s = 2.55 +/- 0.08 mag) field L dwarfs yet detected, making this object an important member of the class of unusually red L dwarfs. We discuss evidence for thick condensate clouds and speculate on the age of the object. Although models by different research groups agree that thick clouds can explain the red spectrum, they predict dramatically different effective temperatures, ranging from 1100 K to 1600 K. This brown dwarf is well suited for additional studies of extremely dusty substellar atmospheres because it is relatively bright (K-s = 13.05 +/- 0.03 mag), which should also contribute to an improved understanding of young gas-giant planets and the transition between L and T brown dwarfs.

TI GRB110721A: AN EXTREME PEAK ENERGY AND SIGNATURES OF THE PHOTOSPHERE

AB GRB110721A was observed by the Fermi Gamma-ray Space Telescope using its two instruments, the Large Area Telescope (LAT) and the Gamma-ray Burst Monitor (GBM). The burst consisted of one major emission episode which lasted for similar to 24.5 s (in the GBM) and had a peak flux of (5.7 +/- 0.2) x 10(-5) erg s(-1) cm(-2). The time-resolved emission spectrum is best modeled with a combination of a Band function and a blackbody spectrum. The peak energy of the Band component was initially 15 +/- 2 MeV, which is the highest value ever detected in a GRB. This measurement was made possible by combining GBM/BGO data with LAT Low Energy events to achieve continuous 10-100 MeV coverage. The peak energy later decreased as a power law in time with an index of -1.89 +/- 0.10. The temperature of the blackbody component also decreased, starting from similar to 80 keV, and the decay showed a significant break after similar to 2 s. The spectrum provides strong constraints on the standard synchrotron model, indicating that alternative mechanisms may give rise to the emission at these energies.

AB Based on our measurements of intermodulation distortion in MgB2, we have previously proposed that the pi energy-gap in MgB2 entails six nodal lines [Y.D. Agassi, D. E. Oates, and B. H. Moeckly, Phys. Rev. B 80 (2009) 174522]. Here we report high-precision measurements in MgB2 stripline resonators that show an increase of the penetration depth as the temperature is decreased below 5 K. This increase is consistent with the l = 6 symmetry of the pi energy gap that we have proposed. We interpret the increase as a manifestation of Andreev surface-attached states that are associated with the nodal lines of the pi energy gap. Penetration-depth calculations are in good agreement with our data. To reconcile the present interpretation with existing literature, we review other penetration-depth data, magnetic-impurity and tunneling experiments, and data on the paramagnetic Meissner effect. We conclude that these data do not rule out the interpretation of our experimental data based on a nodal pi energy gap. (C) 2012 Elsevier B. V. All rights reserved.

AB We used preceramic polysiloxane polymers to fabricate superconducting MgB2 composites that are doped with carbon and nanosized inclusions to improve the pinning properties. The polysiloxanes were prepared by atom transfer radical polymerization and the composites were fabricated by the short time spark plasma sintering method. We found that the superconducting critical temperatures were higher than expected from the carbon content found from the X-ray diffraction analysis of the (110) peak of MgB2. To explain this finding we propose that the grains are unevenly doped, with a core-shell distribution. We also found that both, the upper critical fields and the critical current densities are higher in the preceramic-doped samples than in pure MgB2, in agreement with the carbon doping level. When ferrocene-grafted polysiloxane is used, the upper critical field is the largest, while the critical current density is the lowest. We attribute this fact to the fact that the polymer pyrolysis results in iron-based nanostructures which have a pair breaking effect. (C) 2012 Elsevier B. V. All rights reserved.

INFECTIOUS DIARRHEA
AB Purpose of review
Diarrhoea among military travellers deployed globally in conflict and peacekeeping activities remains one of the most important health threats. Here we review recent advances in our understanding of the epidemiology, laboratory identification, treatment and chronic health consequences of this multi-cause infection, and consider the implications for public health management and future research.
Recent findings
The incidence of diarrhoea among deployed military personnel from industrialized countries to lesser developed countries is approximately 30% per month overall, with clinical incidence between 5 and 7% per 100 person-months. The risk appears to be higher early during deployment and is associated with poor hygienic conditions and contaminated food sources. Gaps remain in our understanding of the cause, given the lack of laboratory capability in austere conditions of deployment; however, recent advances in molecular methods of characterization hold promise in improving our detection capabilities. While there have been improvements in understanding of best treatments, more work needs to be done in transforming this knowledge into action and optimizing single-dose antibiotic treatment regimens. Finally, the under recognized burden of chronic consequences of these infections is gaining awareness and reinforces the need to find effective preventive strategies.
Summary
Our understanding of the epidemiology of diarrhoea is improving but further research is needed to fully account for acute operational-focused health impacts as well as the chronic enduring disease impacts. Improved field diagnostics would be of great value to support these efforts.

AB We develop an incomplete-markets q-theoretic model to study entrepreneurship dynamics. Precautionary motive, borrowing constraints, and capital illiquidity lead to underinvestment, conservative debt use, under-consumption, and less risky portfolio allocation. The endogenous liquid wealth-illiquid capital ratio w measures time-varying financial constraint. The option to accumulate wealth before entry is critical for entrepreneurship. Flexible exit option is important for risk management purposes. Investment increases and the private marginal value of liquidity decreases as w decreases and exit becomes more likely, contrary to predictions of standard financial constraint models. We show that the idiosyncratic risk premium is quantitatively significant, especially for low w. (c) 2012 Elsevier B.V. All rights reserved.

AB This work presents an iterative-deepening A(au) (IDA(au)) based approach to the traveling tournament problem (TTP). The TTP is a combinatorial optimization problem which abstracts the Major League Baseball schedule. IDA(au) is able to find optimal solutions to this problem, with performance improvements coming from the incorporation of various past concepts including disjoint pattern databases, symmetry breaking, and parallelization along with new ideas of subtree skipping, forced deepening, and elite paths to help to reduce the search space. The results of this work show that an IDA(au) based approach can find known optimal solutions to most TTP instances much faster than past approaches. More importantly, it has been able to optimally solve two larger instances that have been unsolved since the problem's introduction in 2001. In addition, a new problem set called GALAXY is introduced, using a 3D space to create a challenging problem set.

AB The Department of Defense is aggressively addressing combat stress reactions (CSRs) through comprehensive Combat/Operational Stress Control (COSC) briefings/programs and referral resources for the prevention, identification, and treatment of stress reactions. The purpose of this study was to develop and administer a survey to assess perceptions of CSRs and barriers to care which affect help-seeking behavior in Marines attending the COSC program. A sample of 553 U.S. Marine Corps Officers and Enlisted personnel from Air (44%), Logistics (38%), and Infantry (18%) communities were recruited for the survey. The results suggested that misconceptions and stigma about CSRs still persist in Marines. The findings reinforced the need to facilitate treatment utilizatiori by focusing on mental health-related stigma as well as organizational barriers.

TI The scattering properties of horizontally aligned snow crystals and

SO RADIO SCIENCE
LA English
DT Article
AB The capability of current and future sensors to make accurate measurements of polarized microwave radiation allows for the investigation of particle shape and orientation. Additionally, the dichroic properties of media consisting of particles with preferential alignment will alter the polarization state of radiation emitted and reflected by the surface below a cloud boundary. Therefore, a deep understanding of the influence of particle orientation and shape upon radiation are required for remote sensing of both cloud and surface properties. In this study, we compute the scattering properties of three horizontally aligned snow crystals: two dendrites and an hexagonal plate. Additionally, we create two approximations using cylindrical plates. One uses a plate with a diameter equal to the maximum dimension of the respective snow crystal, utilizing an effective dielectric model which assumes the disk to be a matrix of ice with air inclusions. The other approximation uses a cylindrical plate of equal mass, with a radius chosen to conserve mass. To simplify the analysis, all particles have equal thickness. The results show a strong polarization response, particularly in the Q element of the Stokes vector. This polarization response is captured well by the two approximations. While the approximations are applicable for certain cases, there are discrepancies between the scattering properties of the idealized snow crystals and the two cylindrical plate models that may limit the generality of the approximations. Further radiative transfer studies are required to test the full applicability of the crystal approximations.

Surface morphology was examined by non-contact mode atomic force microscopy before and after thermal annealing process performed at 700, 800, 900, and 1000 degrees C for 1 h, in air. Wafers with optimum surface quality submitted to thermal annealing treatment at 900 degrees C were characterized by reduced scratched density and residual stress, and surface roughness of 0.096 nm. Surface quality improvement was confirmed by relatively large recovery of the room temperature near band edge luminescence intensity. (C) 2012 Elsevier B.V. All rights reserved.

ID LIMITS
AB This paper investigates the fundamental performance limits of medium access control (MAC) protocols for particular multihop, RF-based wireless sensor networks and underwater sensor networks. A key aspect of this study is the modeling of a fair-access criterion that requires sensors to have an equal rate of underwater frame delivery to the base station. Tight upper bounds on network utilization and tight lower bounds on the minimum time between samples are derived for fixed linear and grid topologies. The significance of these bounds is two-fold: First, they hold for any MAC protocol under both single-channel and half-duplex radios; second, they are provably tight. For underwater sensor networks, under certain conditions, we derive a tight upper bound on network utilization and demonstrate a significant fact that the utilization in networks with propagation delay is larger than that in networks with no propagation delay. The challenge of this work about underwater sensor networks lies in the fact that the propagation delay impact on underwater sensor networks is difficult to model. Finally, we explore bounds in networks with more complex topologies.

AB Our previous work concluded that the application of force altered the physical structure of the activated carbon electrodes, which resulted in a decrease in the accessible surface area and a displacement of the electrolyte. In this work, the response that different carbon material electrodes exhibit to an applied force was evaluated. Activated carbon powders possess different porous structures, which would exhibit different behaviors when subjected to an applied force and after the release of that force. Cyclic voltammetry and electrochemical impedance spectroscopy (EIS) were used to characterize the response behaviors of the different carbons. Furthermore, a porosimetry analysis was conducted on the carbon material of the electrode before and after the application of force. It was concluded that the application of force shifted the pore distribution toward overall smaller pores through a compression of the porous structure of the carbon. This resulted in a decrease in the more easily accessible surface area, which was exhibited as a decrease in the capacitance values as calculated from the cyclic voltammetry data. There was no longer sufficient time to access the now smaller powers at the given time scale of the cyclic voltammetry analysis, which negatively impacted the formation of the double layer.

AB The hydrothermal reactions of various Cu(II) salts with 3- and 4-pyridinetetrazole and pyrazinetetrazole were exploited in the preparation of a series of Cu(II) and Cu(I) azolate materials. The parent copper/pyridyltetrazole compositions are observed in the two-dimensional [Cu(3-pyrtet)(2)] (1), the reduced three-dimensional [Cu(4-pyrtet)] (2) and reduced two-dimensional [Cu(4-pyrtet)].0.5DMF (3.0.5DMF) (Hpyrtet = pyridyltetrazole). The consequences of introducing coordinating anions are revealed in the structures of the one-dimensional [CuCl2(4-Hpyrtet)].0.5H(2)O (4.0.5H(2)O) and the two-dimensional [Cu2I2(4-Hpyrtet)] (5) and [Cu(acac)(4-pyrtet)] (7) (acac = acetylacetonate; H(2)en = ethylenediammonium cation). The pyrazinetetrazolate derivative [H(2)en] 0.5[CuCl2(prztet)] (Hprztet = pyrazinetetrazole) (6) is one-dimensional, but structurally distinct from the chain observed for 4. (c) 2012 Elsevier B.V.

AB The electrochemical behavior of magnesium perchlorate in an ionic liquid, 1,2-dimethyl-3-octylimidazolium bis(trifluoromethanesulfonyl)imide, is characterized using RuO2 as the cathode and Mg foil as the anode material. Electrochemical results indicated that the maximum Mg content intercalated into RuO2 resulted in Mg0.25RuO2, with an initial capacity of 101 mAh/g. X-ray diffraction studies of the Mg-intercalated RuO2 indicated a large expansion of the unit cell and a decrease from cubic to monoclinic symmetry. X-ray diffraction studies and structural analysis suggest a similarity between the structure of Mg0.25RuO2 and Li2RuO3. Charge/discharge experiments at a C/3 rate were performed vs. Mg metal. Results indicated that the capacity decreased significantly with cycling, most likely due to the strong interaction of Mg2+ with the oxide lattice of RuO2. Published by Elsevier Ltd.

TI Titan airglow during eclipse
SO GEOPHYSICAL RESEARCH LETTERS
LA English
DT Article
AB Solar XUV photons can provide enough energy to account for the observed nitrogen UV dayglow emissions above 800 km, but a small or sporadic contribution from energetic particles cannot be ruled out. Furthermore, ion production at altitudes deeper than 800 km as inferred from radio occultation cannot be produced by solar XUV stimulation and implies energy deposition from protons and oxygen ions. Here we examine UV spectra and visible-wavelength images of Titan in Saturn's shadow, when XUV stimulation is absent. UV emissions are observed in one of the three sets of spectra, and the intensity of these emissions is about a factor of 10 less than the peak intensity reported on the dayside. We observe visible-wavelength emissions for the first time. No horizontally resolved auroral structures are seen in the visible images. At visible wavelengths Titan has a global emission at the haze-top level that is not understood, although cosmic ray ionization and chemiluminescence are candidates needing further investigation.

AB We study the probability distribution and the escape rate in systems with delayed dissipation that comes from the coupling to a thermal bath. To logarithmic accuracy in the fluctuation intensity, the problem is reduced to a variational problem. It describes the most probable fluctuational paths, which are given by acausal equations due to the delay. In thermal equilibrium, the most probable path passing through a remote state has time-reversal symmetry, even though one cannot uniquely define a path that starts from a state with given system coordinate and momentum. The corrections to the distribution and the escape activation energy for small delay and small noise correlation time are obtained in explicit form.

TI Frequency-wavenumber velocity spectra, Taylor's hypothesis, and length
scales in a natural gravel bed river
SO WATER RESOURCES RESEARCH
LA English
DT Article
ID DEPTH-LIMITED FLOW; OPEN-CHANNEL FLOW; TURBULENT-FLOW
AB Macroscale turbulent coherent flow structures in a natural fast-flowing river were examined with a combination of a novel 2 MHz Acoustic Doppler Beam (ADB) and a Maximum Likelihood Estimator (MLE) to characterize the streamwise horizontal length scales and persistence of coherent flow structures by measuring the frequency (f)-streamwise-wavenumber (k(s)) energy density velocity spectrum, E(f, k(s)), for the first time in natural rivers. The ADB was deployed under a range of Froude numbers (0.1-0.6) at high Reynolds numbers (similar to 10(6)) based on depth and velocity conditions within a gravel bed reach of the Kootenai River, Idaho. The MLE employed on the ADB data increased our ability to describe river motions with relatively long (>10 m) length scales in similar to 1 m water depths. The E(f, k(s)) spectra fell along a ridge described by V = f/k(s), where V is the mean velocity over depth, consistent with Taylor's hypothesis. New, consistent length scale measures are defined based on averaged wavelengths of the low-frequency E(f, k(s)) and coherence spectra. Energetic (similar to 50% of the total spectral energy), low-frequency (f < 0.05 Hz) streamwise motions were found. Mean length scales, L-m, compared with the depth, h, are significantly larger than previously suggested for macroturbulence with L-m/h similar to 28-118. Although the energy appears as low-pass white noise, it is streamwise coherent along the length of the array. In fast flows with velocities > 1 m/s, L-m were found to be significantly longer than their corresponding coherence lengths, suggesting that the turbulent structures evolve rapidly under these conditions. This is attributed to the stretching and concomitant deformation of preexisting macroturbulent motions by the ubiquitous bathymetry-induced spatial flow accelerations present in a natural gravel bed river.

TI Perioperative Dexamethasone Administration and Risk of Bleeding
Following Tonsillectomy in Children A Randomized Controlled Trial

AB Context Corticosteroids are commonly given to children undergoing tonsillectomy to reduce postoperative nausea and vomiting; however, they might increase the risk of perioperative and postoperative hemorrhage.
Objective To determine the effect of dexamethasone on bleeding following tonsillectomy in children.
Design, Setting, and Patients A multicenter, prospective, randomized, double-blind, placebo-controlled study at 2 tertiary medical centers of 314 children aged 3 to 18 years undergoing tonsillectomy without a history of bleeding disorder or recent corticosteroid medication use and conducted between July 15, 2010, and December 20, 2011, with 14-day follow-up. We tested the hypothesis that dexamethasone would not result in 5% more bleeding events than placebo using a noninferiority statistical design.
Intervention A single perioperative dose of dexamethasone (0.5 mg/kg; maximum dose, 20 mg), with an equivalent volume of 0.9% saline administered to the placebo group.
Main Outcome Measures Rate and severity of posttonsillectomy hemorrhage in the 14-day postoperative period using a bleeding severity scale (level I, self-reported or parent-reported postoperative bleeding; level II, required inpatient admission for postoperative bleeding; or level III, required reoperation to control postoperative bleeding).
Results One hundred fifty-seven children (median [interquartile range] age, 6 [4-8] years) were randomized into each study group, with 17 patients (10.8%) in the dexamethasone group and 13 patients (8.2%) in the placebo group reporting bleeding events. In an intention-to-treat analysis, the rates of level I bleeding were 7.0% (n = 11) in the dexamethasone group and 4.5% (n = 7) in the placebo group (difference, 2.6%; upper limit 97.5% CI, 7.7%; P for noninferiority = .17); rates of level II bleeding were 1.9% (n = 3) and 3.2% (n = 5), respectively (difference, -1.3%; upper limit 97.5% CI, 2.2%; P for noninferiority < .001); and rates of level III bleeding were 1.9% (n = 3) and 0.6% (n = 1), respectively (difference, 1.3%; upper limit 97.5% CI, 3.8%; P for noninferiority = .002).
Conclusions Perioperative dexamethasone administered during pediatric tonsillectomy was not associated with excessive, clinically significant level II or III bleeding events based on not having crossed the noninferior threshold of 5%. Increased subjective (level I) bleeding events caused by dexamethasone could not be excluded because the noninferiority threshold was crossed.

AB Background: Hemorrhagic shock results in systemic activation of the immune system and leads to ischemia-reperfusion injury. Lymphocytes have been identified as critical mediators of the early innate immune response to ischemia-reperfusion injury, and immunomodulation of lymphocytes may prevent secondary immunologic injury in surgical and trauma patients.
Methods: Yorkshire swine were anesthetized and underwent a grade III liver injury with uncontrolled hemorrhage to induce hemorrhagic shock. Experimental groups were treated with a lymphocyte depletional agent, porcine polyclonal anti-thymocyte globulin (PATG) (n=8) and compared to a vehicle control group (n=9). Animals were observed over a 3 day survival period. Circulating lymphocytes were examined with FACS analysis for CD3/CD4/CD8, and central lymphocytes with mesenteric lymph node and spleen staining for CD3. Circulating and lung tissue16 infiltrating neutrophils were measured. Circulating CD3 lymphocytes in the blood and in central lymphoid organs (spleen/lymph node) were stained and evaluated using FACS analysis. Immune-related gene expression from liver tissue was quantified using RT-PCR.
Results: The overall survival was 22% (2/9) in the control and 75% (6/8) in the PATG groups, p=0.09; during the reperfusion period (following hemorrhage) survival was 25% (2/8) in the control and 100% (6/6) in the PATG groups, p=0.008. Mean blood loss and hemodynamic profiles were not significantly different between the experimental and control groups. Circulating CD3(+)CD4(+) lymphocytes were significantly depleted in the PATG group compared to control. Lymphocyte depletion in the setting of hemorrhagic shock also significantly decreased circulating and lung tissue infiltrating neutrophils, and decreased expression of liver ischemia gene expression.
Conclusions: Lymphocyte manipulation with a depletional (PATG) strategy improves reperfusion survival in experimental hemorrhagic shock using a porcine liver injury model. This proof of principle study paves the way for further development of immunomodulation approaches to ameliorate secondary immune injury following hemorrhagic shock.

AB Most environmental satellite radiometers use solar reflectance information when it is available during the day but must resort at night to emission signals from infrared bands, which offer poor sensitivity to low-level clouds and surface features. A few sensors can take advantage of moonlight, but the inconsistent availability of the lunar source limits measurement utility. Here we show that the Day/Night Band (DNB) low-light visible sensor on the recently launched Suomi National Polar-orbiting Partnership (NPP) satellite has the unique ability to image cloud and surface features by way of reflected airglow, starlight, and zodiacal light illumination. Examples collected during new moon reveal not only meteorological and surface features, but also the direct emission of airglow structures in the mesosphere, including expansive regions of diffuse glow and wave patterns forced by tropospheric convection. The ability to leverage diffuse illumination sources for nocturnal environmental sensing applications extends the advantages of visible-light information to moonless nights.

REYNOLDS-NUMBER; FREE SHEAR-LAYER; GRAVITY-CAPILLARY; STOKES LAYER;
EVOLUTION; GENERATION; FLOW
AB Nonlinear interactions between free-surface waves of the same wave speed and wind are studied by extending the linear resonant theory of Miles (J. Fluid Mech., vol. 3, 1957, pp. 185-204). A nonlinear interaction can occur when the steepness of a primary three-dimensional wave, which propagates obliquely to the wind direction, becomes of the order of the cube of the density ratio of air to water. If a secondary wave of smaller amplitude is also an oblique wave, the nonlinear critical-layer interaction between the primary and secondary fluctuations in air generates a difference mode whose wavenumbers are equal to the differences between the primary and secondary values. In addition, the nonlinear interaction in the critical layer between the primary and difference modes induces a parametric-growth effect on the secondary surface wave, if the frequency of the primary wave is higher than that of the secondary wave. The primary wave remains linear during this '2 + 1 mode critical-layer interaction' stage between two free-surface waves and a nonlinearly generated mode. The evolution of the secondary-wave amplitude is governed by an integro-differential equation and that of the difference mode is determined by an integral equation. Both inviscid and viscous numerical results show that the nonlinear growth rates become much larger than the linear growth rates. Effect of viscosity is shown to delay the onset of the nonlinear growth. The growth of the secondary and difference modes is more effectively enhanced when the signs of propagation angles of the primary and secondary waves are opposite than when they are equal. The 2 C 1 mode interaction can occur when wave steepnesses are very small. The nonlinear interaction is entirely confined to a thin critical layer, and the perturbations outside the critical layer are governed by linear equations. It is shown that the initial nonlinear growth of a free-surface wave could be governed by a mode-mode interaction in air.

TI On sound generated by gas-jet impingement on a bubbly gas-water
interface, with application to supercavity self-noise
SO JOURNAL OF SOUND AND VIBRATION
LA English
DT Article
ID FLOW
AB An analysis is made of the sound produced when a high speed turbulent gas jet impinges at normal incidence on a planar gas-water interface in the presence of a uniform, thin homogeneous bubble layer between the gas and the water. It is shown that the bubble layer exhibits a behaviour similar to a 'quarter-wave' resonator, storing energy supplied by gas impingement which is subsequently released as high amplitude sound into the water. In the absence of bubbles the radiation into the water has dipole characteristics, peaking strongly in the direction normal to the interface. The bubbles diffuse this sharp dipole lobe, and are predicted to increase the sound power in the water by up to 10 dB or more over a range of intermediate frequencies when the layer properties are similar to those encountered in experiments using a model scale supercavitating vehicle. At higher frequencies, in the range important for vehicle guidance and control, the bubble layer tends to reduce this source of self-noise. The same mechanism of resonant amplification should be effective more generally, when the bubbles lie within a more confined surface envelope, such as the surface 'wake' of the jet impact zone, whose shape defines a different set of interior eigenmodes.

DE Bayesian network; bathymetry; database; uncertainty
ID SEA-FLOOR TOPOGRAPHY; ALGORITHMS; ERRORS
AB A Bayesian network approach has been developed to estimate uncertainties for gridded bathymetry models that store grids of large regional or worldwide bathymetry. A previous technique to estimate uncertainty for historical data uses Monte Carlo simulations to estimate uncertainty using soundings data, but it is infeasible to implement for gridded bathymetry models. The Bayesian network is designed to estimate uncertainty using gridded bathymetry and a distribution of navigation uncertainties for the survey data used to create the grid as inputs. This paper discusses how the Monte Carlo technique is used to train the network and how to implement it to estimate gridded uncertainty. A demonstration of this approach is presented that uses the data from the original paper for the Monte Carlo technique. Both Monte Carlo and Bayesian network estimators provide higher uncertainty with bottom slope. The Bayesian network estimate is generally greater than the Monte Carlo approach, which is by design for navigation safety, but is within an order of magnitude agreement.

AB Local and nonlocal reaction-diffusion models have been shown to demonstrate nontrivial steady state patterns known as Turing patterns. That is, solutions which are initially nearly homogeneous form non-homogeneous patterns. This paper examines the pattern selection mechanism in systems which contain nonlocal terms. In particular, we analyze a mixed reaction-diffusion system with Turing instabilities on rectangular domains with periodic boundary conditions. This mixed system contains a homotopy parameter beta to vary the effect of both local ( beta = 1) and nonlocal (beta = 0) diffusion. The diffusion interaction length relative to the size of the domain is given by a parameter epsilon. We associate the nonlocal diffusion with a convolution kernel, such that the kernel is of order epsilon(-theta) in the limit as epsilon -> 0. We prove that as long as 0 <= theta < 1, in the singular limit as epsilon -> 0, the selection of patterns is determined by the linearized equation. In contrast, if theta = 1 and beta is small, our numerics show that pattern selection is a fundamentally nonlinear process.

AB The emerging field of compressive sampling has potentially powerful implications for the design of analog-to-digital sampling systems. In particular, the mathematics of compressive sampling suggests that one can recover a signal at a smaller sampling interval than is dictated by the rate at which the samples are digitized. In a recent work the authors presented an all-photonic implementation of such a system and experimentally demonstrated the basic operating principles. This paper offers a more in-depth study of the system, including a more detailed description of the hardware, issues involved in real-time implementation, and how choice of signal model and model fidelity can influence the reconstruction.

FLARES

ID PARTICLE-ACCELERATION; DYNAMICS; FLOWS
AB One of the leading models for electron acceleration in solar flares is stochastic acceleration by weakly turbulent fast magnetosonic waves ("fast waves"). In this model, large-scale flows triggered by magnetic reconnection excite large-wavelength fast waves, and fast-wave energy then cascades from large wavelengths to small wavelengths. Electron acceleration by large-wavelength fast waves is weak, and so the model relies on the small-wavelength waves produced by the turbulent cascade. In order for the model to work, the energy cascade time for large-wavelength fast waves must be shorter than the time required for the waves to propagate out of the solar-flare acceleration region. To investigate the effects of wave escape, we solve the wave kinetic equation for fast waves in weak turbulence theory, supplemented with a homogeneous wave-loss term. We find that the amplitude of large-wavelength fast waves must exceed a minimum threshold in order for a significant fraction of the wave energy to cascade to small wavelengths before the waves leave the acceleration region. We evaluate this threshold as a function of the dominant wavelength of the fast waves that are initially excited by reconnection outflows.

AB The evolution of orientation-dependent metastable states during shock-induced solid-liquid phase transitions in crystalline Al is followed using moving window molecular dynamics simulations. The orientation-dependent transition pathways towards an orientation-independent final state Hugoniot include both "cold melting'' followed by recrystallization in [110]- and [111]-oriented shock waves and crystal overheating followed by melting in [100] shock waves. The orientation-dependent dynamics take place within a zone that can extend up to hundreds of nanometers behind the shock front.

TI Tropical cyclone and extreme rainfall trends in East Asian summer
monsoon since mid-20th century

AB Proper interpretations of extreme rainfall trends in the Asian monsoon regions are complicated by tropical cyclones (TCs) from tropical oceans, whose rainfall trend may be different from the local monsoon (non-TC) rain. Here we show that the trends over the China summer monsoon region have been distorted by western North Pacific typhoons, which bring rainfall with decreasing frequency and increasing intensity. Typically the latter is not sufficient to overcome the former, so TC-related extreme rainfall trend is smaller than monsoon-related extreme rainfall. The net impact underestimates the increasing trend and overestimates the decreasing trend in monsoon extreme rainfall over most areas. The effect is minimal in the Meiyu rain belt region, but reaches 30% in northeastern and southern China. The largest distortions occur on offshore islands in the main TC paths that underwent significant decadal variations. In Hainan, the -3%/decade trend becomes +7%/decade if typhoon rainfall is removed. An opposite case occurs in Taiwan, where the extreme rainfall trend is hugely inflated by local increases in TC rainfall. These opposite effects emphasize the importance of considering the different mechanisms of rainfall systems in order to avoid mis-attribution of regional effects on extreme rainfall to thermodynamic consequences of global warming.

AB This paper presents remotely sensed neutral temperatures obtained from ultraviolet observations and compares them with temperatures from the NRLMSISE-00 version of the Mass Spectrometer and Incoherent Scatter (MSIS) model (unconstrained and constrained to match the total densities from satellite drag). Latitudinal profiles of the temperatures in the Earth's thermosphere are obtained by inversion of high-resolution (similar to 1.3 angstrom) observations of the (1,1) and (5,4) Lyman-Birge-Hopfield (LBH) bands of N-2. The spectra are from the High resolution Ionospheric and Thermospheric Spectrograph (HITS) instrument aboard the Advanced Research and Global Observation Satellite (ARGOS). The results indicate that on each day examined there was consistency between the remotely sensed thermospheric temperatures, the densities from coincident satellite drag measurements at adjacent altitudes, and the NRLMSISE-00 model.

AB Barnacles adhere permanently to surfaces by secreting and curing a thin interfacial adhesive underwater. Here, we show that the acorn barnacle Balanus amphitrite adheres by a two-step fluid secretion process, both contributing to adhesion. We found that, as barnacles grow, the first barnacle cement secretion (BCS1) is released at the periphery of the expanding base plate. Subsequently, a second, autofluorescent fluid (BCS2) is released. We show that secretion of BCS2 into the interface results, on average, in a 2-fold increase in adhesive strength over adhesion by BCS1 alone. The two secretions are distinguishable both spatially and temporally, and differ in morphology, protein conformation, and chemical functionality. The short time window for BCS2 secretion relative to the overall area increase demonstrates that it has a disproportionate, surprisingly powerful, impact on adhesion. The dramatic change in adhesion occurs without measurable changes in interface thickness and total protein content. A fracture mechanics analysis suggests the interfacial material's modulus or work of adhesion, or both, were substantially increased after BCS2 secretion. Addition of BCS2 into the interface generates highly networked amyloid-like fibrils and enhanced phenolic content. Both intertwined fibers and phenolic chemistries may contribute to mechanical stability of the interface through physically or chemically anchoring interface proteins to the substrate and intermolecular interactions. Our experiments point to the need to reexamine the role of phenolic components in barnacle adhesion, long discounted despite their prevalence in structural membranes of arthropods and crustaceans, as they may contribute to chemical processes that strengthen adhesion through intermolecular cross-linking.

AB Geobacter spp. can acquire energy by coupling intracellular oxidation of organic matter with extracellular electron transfer to an anode (an electrode poised at a metabolically oxidizing potential), forming a biofilm extending many cell lengths away from the anode surface. It has been proposed that long-range electron transport in such biofilms occurs through a network of bound redox cofactors, thought to involve extracellular matrix c-type cytochromes, as occurs for polymers containing discrete redox moieties. Here, we report measurements of electron transport in actively respiring Geobacter sulfurreducens wild type biofilms using interdigitated microelectrode arrays. Measurements when one electrode is used as an anode and the other electrode is used to monitor redox status of the biofilm 15 mu m away indicate the presence of an intrabiofilm redox gradient, in which the concentration of electrons residing within the proposed redox cofactor network is higher farther from the anode surface. The magnitude of the redox gradient seems to correlate with current, which is consistent with electron transport from cells in the biofilm to the anode, where electrons effectively diffuse from areas of high to low concentration, hopping between redox cofactors. Comparison with gate measurements, when one electrode is used as an electron source and the other electrode is used as an electron drain, suggests that there are multiple types of redox cofactors in Geobacter biofilms spanning a range in oxidation potential that can engage in electron transport. The majority of these redox cofactors, however, seem to have oxidation potentials too negative to be involved in electron transport when acetate is the electron source.

DE Lagrangian Coherent Structures; Water quality; Dynamical systems;
Coastal circulation; Tidal regime
ID MARINE; ENTEROCOCCI; FLOWS; ZONE
AB The accumulation of pollutants near the shoreline can result in low quality coastal water with negative effects on human health. To understand the role of mixing by tidal flows in coastal water quality we study the nearshore Lagrangian circulation. Specifically, we reveal Lagrangian Coherent Structures (LCSs), i.e., distinguished material curves which shape global mixing patterns and thus act as skeletons of the Lagrangian circulation. This is done using the recently developed geodesic theory of transport barriers. Particular focus is placed on Hobie Beach, a recreational subtropical marine beach located in Virginia Key, Miami, Florida. According to studies of water quality, Hobie Beach is characterized by high microbial levels. Possible sources of pollution in Hobie Beach include human bather shedding, dog fecal matter, runoff, and sand efflux at high tides. Consistent with the patterns formed by satellite-tracked drifter trajectories, the LCSs extracted from simulated currents reveal a Lagrangian circulation favoring the retention near the shoreline of pollutants released along the shoreline, which can help explain the low quality water registered at Hobie Beach.

AB We have carried out a NanoSIMS C, N and O ion imaging study of the CO3.0 chondrite ALHA77307. The distribution of O-anomalous grains in ALHA77307 is similar to that observed in other primitive meteorites, and is dominated (84%) by O-17-rich Group 1 grains from low-mass asymptotic giant branch (AGB) stars of close-to-solar metallicity. Four percent of the grains belong to Group 2, whose O-18 depletions suggest cool-bottom processing in low-mass stars during the AGB phase, while 8% are Group 4 grains with likely origins in Type II supernova (SN) ejecta. One ferromagnesian silicate has a very high O-17 enrichment; nova explosions have been suggested as sources for such grains, but recent models with updated reaction rates show large discrepancies with the grain data, leaving the origins of these grains uncertain.
Most of the grains are silicates (86%) with the remainder consisting of oxides (8%), three silica grains and two 'composite' grains composed of multiple subgrains with different elemental compositions. The elemental compositions of the silicates are similar to those found in other studies, with a predominance of non-stoichiometric compositions and high (up to 44 at.%) Fe concentrations. A comparison of isotopic and elemental compositions for all presolar silicates shows that olivine compositions are overabundant in Group 4 grains compared to grains from Groups 1 and 2. This may reflect injection of presolar material from a nearby supernova into the early solar nebula and incorporation into parent bodies before alteration of compositions through irradiation and sputtering in the interstellar medium, as is likely to have occurred for the Group 1 and 2 grains from more distant AGB stars.
The matrix material in ALHA77307 contains abundant carbonaceous hotspots with excesses in N-15. However, unlike CR chondrites, the insoluble organic matter (IOM) in ALHA77307 does not have a bulk N isotopic anomaly, consistent with Raman evidence that it has experienced more processing than IOM from CR chondrites. Nevertheless, secondary processing has clearly not been so pervasive as to lead to complete destruction of N isotopic anomalies in this meteorite. Moreover, presolar silicate abundances and elemental compositions show little evidence for thermal processing, indicating a decoupling of the effects of metamorphism on organic matter and matrix silicates.

AB Microwave remote sensing can provide reliable measurements of surface soil moisture. However, some land surface conditions can have a perturbing influence on soil moisture retrievals. In the soil moisture experiments in 2005 (SMEX05), we attempted to contribute to the understanding of the effect of dew using concurrent ground and aircraft observations. Early morning flights were conducted with an airborne microwave radiometer from June 19 to July 2, 2005, in Iowa, USA over an agricultural domain. Results of the experiment indicated that dew had a small but measurable effect on the observed 10.7-GHz brightness temperatures. The results indicate that the H-pol emissivity increased 0.015 to 0.04 for the corn sites, 0.014 to 0.02 for soybean, and 0.01 for forest sites as dew evaporated. These results suggest that the presence of dew decreases X-band land surface emissivity slightly and the effect of dew varies with vegetation types. Our findings are consistent with other works in the literature that has found that the effect of dew depends on both the type of vegetation and the wavelength of observation, but further studies should be conducted to verify this hypothesis.

TI Demonstration of Anisotropic Fluid Closure Capturing the Kinetic
Structure of Magnetic Reconnection
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID MAGNETOTAIL
AB Collisionless magnetic reconnection in high-temperature plasmas has been widely studied through fluid-based models. Here, we present results of fluid simulation implementing new equations of state for guide-field reconnection. The new fluid closure accurately accounts for the anisotropic electron pressure that builds in the reconnection region due to electric and magnetic trapping of electrons. In contrast to previous fluid models, our fluid simulation reproduces the detailed reconnection region as observed in fully kinetic simulations. We hereby demonstrate that the new fluid closure self-consistently captures all the physics relevant to the structure of the reconnection region, providing a gateway to a renewed and deeper theoretical understanding of reconnection in weakly collisional regimes.

AB Background: Limited information exists on the epidemiology of acute febrile respiratory illnesses in tropical South American countries such as Venezuela. The objective of the present study was to examine the epidemiology of influenza-like illness (ILI) in two hospitals in Maracay, Venezuela.
Methodology/Principal Findings: We performed a prospective surveillance study of persons with ILI who presented for care at two hospitals in Maracay, Venezuela, from October 2006 to December 2010. A respiratory specimen and clinical information were obtained from each participant. Viral isolation and identification with immunofluorescent antibodies and molecular methods were employed to detect respiratory viruses such as adenovirus, influenza A and B, parainfluenza, and respiratory sincytial virus, among others. There were 916 participants in the study (median age: 17 years; range: 1 month - 86 years). Viruses were identified in 143 (15.6%) subjects, and one participant was found to have a co-infection with more than one virus. Influenza viruses, including pandemic H1N1 2009, were the most frequently detected pathogens, accounting for 67.4% (97/144) of the viruses detected. Adenovirus (15/144), parainfluenza virus (13/144), and respiratory syncytial virus (11/144) were also important causes of ILI in this study. Pandemic H1N1 2009 virus became the most commonly isolated influenza virus during its initial appearance in 2009. Two waves of the pandemic were observed: the first which peaked in August 2009 and the second - higher than the preceding - that peaked in October 2009. In 2010, influenza A/H3N2 re-emerged as the most predominant respiratory virus detected.
Conclusions/Significance: Influenza viruses were the most commonly detected viral organisms among patients with acute febrile respiratory illnesses presenting at two hospitals in Maracay, Venezuela. Pandemic H1N1 2009 influenza virus did not completely replace other circulating influenza viruses during its initial appearance in 2009. Seasonal influenza A/H3N2 was the most common influenza virus in the post-pandemic phase.

NETWORKS; BEHAVIOR; CONTAGION; DIFFUSION; CONSENSUS; AGENTS
AB We develop a sequence of models describing information transmission and decision dynamics for a network of individual agents subject to multiple sources of influence. Our general framework is set in the context of an impending natural disaster, where individuals, represented by nodes on the network, must decide whether or not to evacuate. Sources of influence include a one-to-many externally driven global broadcast as well as pairwise interactions, across links in the network, in which agents transmit either continuous opinions or binary actions. We consider both uniform and variable threshold rules on the individual opinion as baseline models for decision making. Our results indicate that (1) social networks lead to clustering and cohesive action among individuals, (2) binary information introduces high temporal variability and stagnation, and (3) information transmission over the network can either facilitate or hinder action adoption, depending on the influence of the global broadcast relative to the social network. Our framework highlights the essential role of local interactions between agents in predicting collective behavior of the population as a whole.

AB For the first time, the kinematic evolution of a coronal wave over the entire solar surface is studied. Full Sun maps can be made by combining images from the Solar Terrestrial Relations Observatory satellites, Ahead and Behind, and the Solar Dynamics Observatory, thanks to the wide angular separation between them. We study the propagation of a coronal wave, also known as the "Extreme Ultraviolet Imaging Telescope" wave, and its interaction with a coronal hole (CH) resulting in secondary waves and/or reflection and transmission. We explore the possibility of the wave obeying the law of reflection. In a detailed example, we find that a loop arcade at the CH boundary cascades and oscillates as a result of the extreme ultraviolet (EUV) wave passage and triggers a wave directed eastward that appears to have reflected. We find that the speed of this wave decelerates to an asymptotic value, which is less than half of the primary EUV wave speed. Thanks to the full Sun coverage we are able to determine that part of the primary wave is transmitted through the CH. This is the first observation of its kind. The kinematic measurements of the reflected and transmitted wave tracks are consistent with a fast-mode magnetohydrodynamic wave interpretation. Eventually, all wave tracks decelerate and disappear at a distance. A possible scenario of the whole process is that the wave is initially driven by the expanding coronal mass ejection and subsequently decouples from the driver and then propagates at the local fast-mode speed.

AB We report on our serendipitous pre-discovery detection and follow-up observations of the broad-lined Type Ic supernova (SN Ic) 2010ay at z = 0.067 imaged by the Pan-STARRS1 3 pi survey just similar to 4 days after explosion. The supernova (SN) had a peak luminosity, M-R approximate to -20.2 mag, significantly more luminous than known GRB-SNe and one of the most luminous SNe Ib/c ever discovered. The absorption velocity of SN 2010ay is v(Si) approximate to 19 x 10(3) km s(-1) at similar to 40 days after explosion, 2-5 times higher than other broad-lined SNe and similar to the GRB-SN 2010bh at comparable epochs. Moreover, the velocity declines similar to 2 times slower than other SNe Ic-BL and GRB-SNe. Assuming that the optical emission is powered by radioactive decay, the peak magnitude implies the synthesis of an unusually large mass of Ni-56, M-Ni = 0.9M(circle dot). Applying scaling relations to the light curve, we estimate a total ejecta mass, M-ej approximate to 4.7 M-circle dot, and total kinetic energy, E-K approximate to 11 x 10(51) erg. The ratio of M-Ni to M-ej is similar to 2 times as large for SN 2010ay as typical GRB-SNe and may suggest an additional energy reservoir. The metallicity (log(O/H)(PP04) + 12 = 8.19) of the explosion site within the host galaxy places SN 2010ay in the low-metallicity regime populated by GRB-SNe, and similar to 0.5(0.2) dex lower than that typically measured for the host environments of normal (broad-lined) SNe Ic. We constrain any gamma-ray emission with E-gamma less than or similar to 6 x 10(48) erg (25-150 keV), and our deep radio follow-up observations with the Expanded Very Large Array rule out relativistic ejecta with energy E greater than or similar to 10(48) erg. We therefore rule out the association of a relativistic outflow like those that accompanied SN 1998bw and traditional long-duration gamma-ray bursts (GRBs), but we place less-stringent constraints on a weak afterglow like that seen from XRF 060218. If this SN did not harbor a GRB, these observations challenge the importance of progenitor metallicity for the production of relativistic ejecta and suggest that other parameters also play a key role.

TI Ion-neutral-atom sympathetic cooling in a hybrid linear rf Paul and

AB Long-range polarization forces between ions and neutral atoms result in large elastic scattering cross sections (e. g., similar to 10(6) a.u. for Na-Na+ or Na-Ca+ at cold and ultracold temperatures). This suggests that a hybrid ion-neutral trap should offer a general means for significant sympathetic cooling of atomic or molecular ions. We present SIMION 7.0 simulation results concerning the advantages and limitations of sympathetic cooling within a hybrid trap apparatus consisting of a linear rf Paul trap concentric with a Na magneto-optical trap (MOT). This paper explores the impact of various heating mechanisms on the hybrid system and how parameters related to the MOT, Paul trap, number of ions, and ion species affect the efficiency of the sympathetic cooling.

AB Passive remote sensing of the Earth system has used spatial resolutions ranging from meters to kilometers. It is thus necessary to understand how data products with different spatial resolutions can be compared with each other, and how sub-pixel variations may affect data comparison. This is particularly important for ocean color remote sensing where the measured signal (water-leaving radiance or remote sensing reflectance) is a non-linear function of sub-surface constituents. As a result, products at low resolution are not necessarily arithmetic or geometric means of those at higher resolution. Here, we developed analytical expressions to link ocean color properties derived from high-and low-resolution data, and the proof-of-concept is further demonstrated with both simple examples and measurements of MERIS full-resolution (FR) and reduced resolution (RR). These results suggest that current global chlorophyll concentration is likely underestimated due to the coarse spatial resolutions. Application of the expressions will facilitate cross-sensor comparisons and may also reduce uncertainties. (C) 2012 Optical Society of America

cascade lasers
SO OPTICS EXPRESS
LA English
DT Article
AB We demonstrate cw output powers >290 mW into a nearly diffraction-limited (M-2 approximate to 2.2) output beam from an interband cascade laser operating at lambda = 3.6-3.7 mu m at room temperature. The interband cascade laser was designed for nearly equal electron and hole populations in the active region with heavy electron-injector doping, and was processed into narrow ridges mounted epitaxial side down on a copper heat sink. A 15.7-mu m-wide, 4-mm-long ridge with the back facet coated for high reflection (HR) and an anti-reflection-coated front facet produced 253 mW of cw output power at T = 25 degrees C into a beam with M-2 approximate to 2.7. Furthermore, corrugating the sidewalls of the ridge leads to a 20% improvement in the brightness. A 15.7-mu m-wide, 0.5-mm-long ridge with an HR-coated back facet and an uncoated front facet exhibited a maximum cw wall-plug efficiency of nearly 15% at room temperature.

AB In this article we report on metamaterial- based narrowband thermal terahertz (THz) emitters with a bandwidth of about 1 THz. Single band emitters designed to radiate in the 4 to 8 THz range were found to emit as high as 36 W/m(2) when operated at 400 degrees C. Emission into two well-separated THz bands was also demonstrated by using metamaterial structures featuring more complex unit cells. Imaging of heated emitters using a microbolometer camera fitted with THz optics clearly showed the expected higher emissivity from the metamaterial structure compared to low-emissivity of the surrounding aluminum.

AB Aircraft measurements during the 2006 Gulf of Mexico Atmospheric Composition and Climate Study (GoMACCS) are used to examine the influence of shallow cumulus clouds on vertical profiles of aerosol chemical composition, size distributions, and secondary aerosol precursor gases. The data show signatures of convective transport of particles, gases and moisture from near the surface to higher altitudes, and of aqueous-phase production of aerosol mass (sulfate and organics) in cloud droplets and aerosol water. In cloudy conditions, the average aerosol volume concentration at an altitude of 2850 m, above typical cloud top levels, was found to be 34% of that at 450 m; for clear conditions, the same ratio was 13%. Both organic and sulfate mass fractions were on average constant with altitude (around 50%); however, the ratio of oxalate to organic mass increased with altitude (from 1% at 450 m to almost 9% at 3450 m), indicative of the influence of in-cloud production on the vertical abundance and characteristics of secondary organic aerosol (SOA) mass. A new metric termed "residual cloud fraction" is introduced as a way of quantifying the "cloud processing history" of an air parcel. Results of a parcel model simulating aqueous phase production of sulfate and organics reproduce observed trends and point at a potentially important role of SOA production, especially oligomers, in deliquesced aerosols. The observations emphasize the importance of shallow cumulus clouds in altering the vertical distribution of aerosol properties that influence both their direct and indirect effect on climate.

AB Density functional theory and molecular dynamics simulations have been used to optimize the structure of nanowires of SiO2. The starting structures were based on beta-cristobalite, ortho-tridymite, beta-tridymite, and rutile crystals. The analysis of the electronic structure has been validated by many-body perturbation calculations using the G(0)W(0) and GW + Bethe-Salpeter equation approximations, to account for quasiparticle and excitonic effects. The calculations indicate that many of these nanowires have semiconducting character, while the corresponding bulk solids are insulators. In the case of thick rutilelike nanowires, we found the gap congested with surface states. Electronic charge is transferred from silicon atoms to oxygen atoms, and the bonding in the nanowires is partly ionic and partly covalent. The magnitude of the band gap can be engineered by changing the structure and the thickness of the nanowires.

SO PHYSICAL REVIEW B
LA English
DT Article
ID DIELECTRIC SOLIDS; MGO; SCATTERING; CRYSTALS; PBTE
AB Using a first-principles approach based on density functional perturbation theory and an exact numerical solution to the phonon Boltzmann equation, we show that application of high compressive hydrostatic pressure dramatically increases the thermal conductivity of diamond. We connect this enhancement to the overall increased frequency scale with pressure, which makes acoustic velocities higher and reduces phonon-phonon scattering rates. Of particular importance is the often-neglected fact that heat-carrying acoustic phonons are coupled through lattice anharmonicity to higher frequency optic modes. An increase in optic mode frequencies with pressure weakens this coupling and contributes to driving the diamond thermal conductivities to far larger values than in any material at ambient pressure and temperature.

AB Given a graph G, its triangular line graph is the graph T(G) with vertex set consisting of the edges of G and adjacencies between edges that are incident in G as well as being within a common triangle. Graphs with a representation as the triangular line graph of some graph G are triangular line graphs, which have been studied under many names including anti-Gallai graphs, 2-in-3 graphs, and link graphs. While closely related to line graphs, triangular line graphs have been difficult to understand and characterize. Van Bang Le asked if recognizing triangular line graphs has an efficient algorithm or is computationally complex. We answer this question by proving that the complexity of recognizing triangular line graphs is NP-complete via a reduction from 3-SAT. Published by Elsevier B.V.

AB Measurements of the differential cross section and the transverse single-spin asymmetry, A(N), vs x(F) for pi(0) and eta mesons are reported for 0.4 < x(F) < 0.75 at an average pseudorapidity of 3.68. A data sample of approximately 6.3 pb(-1) was analyzed, which was recorded during p(up arrow) + p collisions at root s = 200 GeV by the STAR experiment at RHIC. The average transverse beam polarization was 56%. The cross section for pi(0), including the previously unmeasured region of x(F) > 0.55, is consistent with a perturbative QCD prediction, and the eta/pi(0) cross-section ratio agrees with existing midrapidity measurements. For 0.55 < x(F) < 0.75, the average A(N) for eta is 0.210 +/- 0.056, and that for pi(0) is 0.081 +/- 0.016. The probability that these two asymmetries are equal is similar to 3%.

AB We investigate the possibility of a molecular bottom-up approach to the construction of the basic element for optical negative index metamaterials. Undoped and doped graphene-based molecules, including nanotubes, are considered. We employ first-principles and tight-binding electronic structure methods to determine the energy levels and the stability of the molecules. Under certain assumptions, we simulate the electromagnetic response of the molecules by a corresponding network of perfect wires. The nanotubes exhibit a resonant response at the soft x-ray range.

AB Use of biologic graft extenders in spinal fusions is increasing. Multiple allograft alternatives exist to the "gold-standard" autologous bone grafting. The ideal graft extender is osteoconductive, osteoinductive and has osteogenic potential. While the ideal graft extender has yet to be found, available bone graft extenders have varying degrees of predominately osteoconductive and osteoinductive properties. This review will provide an update on available graft extenders including bone morphogenetic proteins, mesenchymal stem cells, and demineralized bone matrix. The goal is to provide a review of the current use in spinal fusions and future directions in biologics for spinal fusion.

ID LEAD-FREE SOLDERS; TENSILE PROPERTIES; MECHANICAL-PROPERTIES;

AB This paper investigates the mechanical behavior of a copper solder interface when subjected to varying strain rate loading between 0.05 s(-1) and 10.0 s(-1). The copper is alloy 101, and the solder is lead-free type with a composition of 96% tin and 4% silver. Both uniform and nonuniform two-level strain rate loadings were applied. For the two-level strain rate loading, the strain rate was changed from one level to another during the loading process as a step change. The strain rate tests were performed at room temperature as well as at an elevated temperature of 65 degrees C. The test results showed significant effects of uniform and nonuniform strain rates as well as temperature on fracture surface, peak stress, fracture strain, modulus, and stored energy density until fracture. Generally, a higher strain rate increased the peak stress and fracture strain, but decreased the modulus. The heated specimens showed significantly reduced strength and fracture strain at high strain rates when compared to the specimens tested at room temperature. For the two-level strain rates, the sequence of the loading rates affected the material behavior significantly. The peak stress under the two-level strain rates might be located outside the range that was determined by the two individual uniform strain rates occurring in the two-level rates. On the other hand, the fracture strain under two-level strain rate loading always fell inside that range. An expression was proposed to predict the interface fracture strains for the case of a two-level strain rate loading based on the data of each respective single-level strain test. The prediction was reasonable when compared to the experimental data with an average absolute error of 10%. [DOI: 10.1115/1.4006862]

TI Spatial Resolution of the Axisymmetric Turbulent Statistics Along Thin
Circular Cylinders at High Transverse Curvatures and Low-Re
SO JOURNAL OF FLUIDS ENGINEERING-TRANSACTIONS OF THE ASME
LA English
DT Article
ID LARGE-EDDY SIMULATION; BOUNDARY-LAYER; AXIAL-FLOW; WALL-PRESSURE;
VELOCITY
AB After three decades of accumulated experimental and numerical results, a comprehensive understanding of the spatial evolution of axisymmetric turbulent boundary layers (ATBL) along long thin cylinders still eludes both scientists and engineers. While experimentalists dealt with axial alignment complexities, computationalists lacked proper inflow boundary conditions. Herein, we correct this latter deficiency and initiate an investigation of the thin cylinder turbulence under low Reynolds numbers and high transverse curvatures (boundary layer thicknesses to radius). Using the large-eddy simulation (LES) methodology, we are particularly interested in the radial propagation of the transverse curvature on the ATBL statistics. A ten-simulation matrix was constructed to examine these effects with validation against the experimental evidence. These tests investigated the ATBL maturity up to transverse curvatures approaching 2 orders of magnitude. A recently developed turbulent inflow procedure for the thin cylinder was implemented that couples a dynamic form of Spalding's expression for rescaling the mean streamwise velocity with recycling of all superimposed turbulent fluctuations. The technique specifically circumvents intensive computations from the cylinder leading edge, and the rescaling-recycling combination minimizes the inflow turbulent regeneration length under very high transverse curvatures. After the initial transition phase in each LES computation, the respective numerical uncertainty was quantified to ensure sufficient spatial resolution within the discretized domain for resolving the energy-bearing scales of the turbulent motion. For the present low-Re conditions, the strength of the log layer steadily diminishes under continuous rise in the transverse curvature whereas the scaled fluctuating intensities elevate (except for the dominate shear stresses) with no sign towards full maturity. Each simulation reveals a boundary layer thickness that grows downstream by a factor of 7 relative to the momentum thickness with a linear influence of the transverse curvature on the wall-shear stress coefficient.

DT Article
ID FIRE; AUSTRALIA
AB On 22 November 2006 a pair of pyrocumulonimbus (pyroCb) storms, roughly 75 km apart, erupted simultaneously in the forests of Wollemi and Blue Mountains National Parks. The so-named Wollemi and Grose Valley fires blew up at an unusual time late morning and injected smoke into the uppermost troposphere. This is the first pyroCb event recorded during active pyroconvection by NASA's A-Train satellite constellation. Hence we show for the first time the pyroconvection column from simultaneous passive imagers, active lidar and radar, and UV backscattering instruments. There are no previous reports of pyroCb activity from Wollemi, and a report of the Grose Valley pyroconvective column limited its vertical extent to 6 km. Here we show, using ground-based radar data, that both fires blew up quasi-simultaneously before local noon. The Grose Valley pyroCb penetrated to the tropopause, the Wollemi pyroCb injection height exceeded the tropopause by 1-3 km. Analysis of a portion of the smoke plume sampled by the A-Train on 23 November confirms tropopause injection altitude. We explore a variety of meteorological observations and analyses to determine that the blow ups on 22 November 2006 (and only on this date in the fires' lifetimes) were mostly a consequence of anomalous boundary layer warmth and wind speed.

AB The structural characteristics of a subsurface cage system for sea cucumber, Stichopus japonicus, grow-out were analyzed by using numerical modeling techniques. The cage system was constructed of polypropylene pipe and netting and weighted to sit on the seafloor bottom. Inside the cage, concrete blocks were used for animal aestivation and weight and a thin-plated device was mounted for animal movement. Environmental loads on the structure, resulting from a prescribed irregular wave field with and without currents, were first determined with a Morison equation-type finite element model. The structural response of beam and truss cage components was then calculated with the software MSC.MARC/Mentat. In addition to the irregular wave and current input forcing parameters of the structure, response was also calculated for possible forces incurred during lifting operations. Reaction loads, bending moments, axial tensions, and von Mises stresses of the sea cucumber cage structure were calculated for evaluation. The results of the study indicate that the combination of numerical model analyses presented can be used to assess structural integrity of these subsurface cage systems. These techniques will become more important as the industry expands and economics of scale promotes the construction of larger sea cucumber containment structures.

AB The efficacy and feasibility of using zerovalent zinc (ZVZ) to treat 1,2,3-trichloropropane (TCP)-contaminated groundwater was assessed in laboratory and field experiments. In the first portion of the study, the reactivity of commercially available granular ZVZ toward TCP was measured in bench-scale batch-reactor and column experiments. These results were used to design columns for on-site pilot-scale treatment of contaminated groundwater at a site in Southern California. Two of the ZVZ materials tested were found to produce relatively high rates of TCP degradation as well as predictable behavior when scaling from bench-scale to field testing. In addition, there was little decrease in the rates of TCP degradation over the duration of field testing. Finally, no secondary impacts to water quality were identified. The results suggest that ZVZ may be an effective and feasible material for use in engineered treatment systems, perhaps including permeable reactive barriers.

ID SEQUENTIAL CONFIDENCE-INTERVALS; SIMULATION; LENGTH
AB Absolute precision stopping rules are often used to determine the length of sequential experiments to estimate confidence intervals for simulated performance measures. Much is known about the asymptotic behavior of such procedures. In this paper, we introduce coverage contours to quantify the trade-offs in interval coverage, stopping times, and precision for finite-sample experiments using absolute precision rules. We use these contours to evaluate the coverage of a basic absolute precision stopping rule, and we show that this rule will lead to a bias in coverage even if all of the assumptions supporting the procedure are true. We define optimal stopping rules that deliver nominal coverage with the smallest expected number of observations. Contrary to previous asymptotic results that suggest decreasing the precision of the rule to approach nominal coverage in the limit, we find that it is optimal to increase the confidence coefficient used in the stopping rule, thus obtaining nominal coverage in a finite-sample experiment. If the simulation data are independent and identically normally distributed, we can calculate coverage contours analytically and find a stopping rule that is insensitive to the variance of the data while delivering at least nominal coverage for any precision value.

AB Subpectoral biceps tenodesis is a minimally invasive surgical technique that efficiently and reproducibly addresses long head of the biceps (LHB) tendon pathology. Indications for biceps tenodesis include traumatic and degenerative tearing, biceps instability, rupture, and failed surgery. Subpectoral tenodesis may be a preferred technique in the setting of complete LHB rupture, failed tenotomy, or prior tenodesis. The LHB tendon is tenotomized arthroscopically at its origin, and a miniopen subpectoral approach is used to identify the tendon distally. Fixation is performed deep and just proximal to the inferior margin of the pectoralis major muscle. Fixation in this area can be achieved through the use of bone tunnels, an interference screw, suture anchor(s), or a cortical button. Attention is given to maintain the native position of the LHB musculotendinous junction relative to the inferior border of the pectoralis major. This technique maintains the biceps length-tension relationship and addresses intertubercular biceps pathology by eliminating pain generators within the bicipital groove. Superior biomechanical properties are achieved using interference screw fixation, and a single suture is added for reinforcement. Complications may occur in approximately 2% of patients and include infection, fixation failure, cosmetic deformity, cramping, fracture, and nerve injury.

AB An all-fiber based supercontinuum source with emission covering the wavelength range of 1.9-4.8 mu m is demonstrated. The laser source is based on a combination of silica commercial off-the shelf components and a chalcogenide-based nonlinear optical fiber. The system provides 10 dB spectral flatness from 2.0 to 4.6 mu m, and -20 dBm points from 1.9 to 4.8 mu m. The output power is 565mW but scalable by scaling the repetition rate. The limit on the long wavelength edge of the system is identified as an extrinsic absorption feature in the fiber used; confirming the system could be scaled to generated a broadband source even further in the infrared.

AB Thin cirrus clouds frequently contaminate satellite images. These clouds are traditionally treated as aerosols in atmospheric correction processes for satellite remote sensing of ocean color. Through analysis of spectral imaging data covering a solar spectral region between approximately 0.4 and 0.9 mu m and acquired with the Hyperspectral Imager for the Coastal Ocean (HICO) instrument currently on board the International Space Station, we have developed an empirical but very effective technique to remove thin cirrus effects from HICO data acquired over fairly clear ocean waters where the water leaving reflectances above 0.8 mu m are close to zero. The development of the technique is based on this property and on the fact that cirrus reflectances in the 0.4-1.0-mu m region are spectrally constant. The empirical technique is described, and sample results are presented. The same technique is applicable to thin cirrus corrections over clear water surfaces for other hyperspectral or multichannel imaging instruments covering similar spectral range.

ID MODEL
AB With the growing adoption of comprehensive health and usage monitoring and evaluation systems tracking military aircraft operations on a flight-by-flight basis, improved reliability of automated procedures that process data has become a priority. One approach to fulfill this need is for the automated data analysis procedures themselves to be capable of ascertaining when their processing may be in error. This can be achieved through the implementation of self-monitoring activities. To capture the level of automation truly necessary to process large quantities of data autonomously, a complimentary capability that allows the self-monitoring activity to learn from its processing experiences by readily incorporating that knowledge into its future processing is also necessary. In this study, self-monitoring activities capable of modifying their functionality autonomously in response to data content are presented. In particular, self-monitoring activities are developed for ensuring the proper operation of monitored signals and algorithms performing signal reconstruction as well as event detection. The entire adaptive self-monitoring analysis is demonstrated and evaluated using flight data from a set of 47 flights obtained from several naval rotorcraft equipped with an integrated mechanical diagnostic system. Additional results are obtained and evaluated for an unbounded data set represented by more than 1000 flights.

ID BLUFF-BODY; DRAG; TUBERCLES; REDUCTION
AB The flowfield and the aerodynamic forces on a two-dimensional airfoil with sinusoidal leading-edge protuberances were computed numerically and compared with the baseline NACA 63(4)-021 airfoil. The amplitude and wavelength of the sinusoidal leading edge were 12 and 50% of the mean chord length. The sinusoidal leading-edge airfoil is dominated by the flow around and over the protuberances at all angles of attack, resulting in significant spanwise variation in all flow properties, in contrast to the baseline airfoil. The surface-pressure distribution on the modified airfoil consists of low-pressure pockets in the troughs that are symmetric and periodic at low angles of attack, and evolve into complicated patterns at higher angles. The low-pressure pockets persist to high angles of attack, resulting in the continued increase of lift. The modified airfoil has lower lift and higher drag in the prestall regime. The lift and drag characteristics at high angles of attack, as well as the dependence on Reynolds number, are addressed in this study.

ID AIRWAKE; FLIGHT; AERODYNAMICS; SIMULATION; INTERFACE; DYNAMICS
AB Velocity measurements in a ship airwake are obtained in situ aboard a 108 ft naval training vessel. The measurements and analyses are motivated by the need for validation data for airwake computational fluid dynamics simulations. Three-component anemometers are placed above the bow of the ship and at numerous locations above a flight deck at the stern of the ship. Data are presented for a direct headwind (nominally 0 deg wind-over-deck). The mean velocity field shows a clear structure to the flow, dominated by a recirculation region in the near-wake of a hangar-like backward-facing step. The location of this primary vortex and the reattachment point on the flight deck are estimated. Reynolds stresses are presented to quantity the turbulent fluctuations, which are required for the prediction of unsteady loading on rotorcraft operating in this environment. Significant anisotropy is measured in the wake, both within the primary vortex and in the far field. The peak Reynolds shear stress is located in the recirculation region, while the streamwise normal stress is found to increase with height throughout the measurement domain. Finally, auto- and two-point velocity correlations from the flight deck provide an estimate of flow scales, showing the potential influence of turbulence on piloted helicopter operations.

AB Hemochromatosis in bottlenose dolphins (Tursiops truncatus) is associated with high postprandial plasma insulin levels, suggestive of insulin resistance. In humans, insulin resistance is associated with liver pathologies, including excessive iron deposition and nonalcoholic fatty liver disease. Dolphin liver tissues, in addition to excessive iron storage, were evaluated for other pathologies supportive of underlying insulin resistance. Archived liver tissues collected postmortem during 1985-2010 from 18 dolphins (median age 27.9 yr, range 0.7-51.4) that were part of the Navy Marine Mammal Program's managed collection were assessed for the presence and severity of hemosiderin deposition, fatty liver disease, and hepatitis. Demographics, clinical pathology values, and percentage weight loss were compared among dolphins with and without these changes. Twelve (66.7%) dolphins had mild to moderate hemosiderin deposition, 7(38.9%) had mild to severe fatty liver disease, and 11(61.1%) had mild to moderate hepatitis. Of the 12 dolphins with hemosiderosis, deposition occurred in the Kupffer cells among 11 (91.7%). Dolphins with fatty liver disease were more likely to have higher postprandial serum hyperglycemia (>140 mg/dl), leukocytosis (>11,000 cells/mu l), and hyperglobulinemia (>3.5 g/dl). Unlike in many nonhuman terrestrial animals, fatty liver disease was not associated with rapid weight loss or hypoglycemia. Interestingly, there were no significant associations among dolphins with hemosiderosis, fatty liver disease, and hepatitis. This study supports that both hemochromatosis and fatty liver disease were present in the dolphin study population, and histopathology and clinical pathology among these animals suggest a nonhereditary, metabolic etiology.

DE Brown Pelican; disturbance; El Nino; nesting; Pelecanus occidentalis;
roosting; San Nicolas Island; Southern California Bight
AB To assist long-term protection of roost sites, roosting patterns of California Brown Pelicans (Pelecanus occidentalis californicus) at San Nicolas Island (SNI), California, were assessed for the 1972-2006 period. SNI was used for roosting year-round, with most birds likely from nearest primary, breeding colonies (Santa Barbara and Anacapa islands) within the Southern California Bight subpopulation. Among non-El Nino years, monthly diurnal counts varied, but ranged from less than 100 birds during the breeding season to approximately 1,000 during fall. Influxes from the large Gulf of California subpopulation also occurred on occasion, best demonstrated by prolonged increased numbers during strong El Nino conditions in 1972-1973, possibly reflecting delayed or skipped breeding and increased prey availability near the outer California Channel Islands. The peak estimate of 13,500 night-roosting pelicans was on 16 November 1972 during these El Nino conditions. Most pelicans roosted diurnally on the north shore, reflecting close proximity to main foraging areas. Diurnal roost patterns did not appear affected by introduced feral cats (Felis catus) and Island Foxes (Urocyon littoralis dickeyi). The single, major night roost shifted 4 km from Cormorant Rock Area (used 1972-1992) to Vizcaino Point by 2006, following reduction of human disturbance in 1992-1996. Vizcaino Point and Cormorant Rock Area should be designated as "key, long-semi roosts" that merit additional protection. Received 25 July 2011, accepted 14 March 2012.

AB A large and increasing share of international humanitarian and development aid is raised from nongovernmental sources, allocated by transnational NGOs. We know little about this private foreign aid, not even how it is distributed across recipient countries, much less what explains the allocation. This article presents an original data set, based on detailed financial records from most of the major U.S.based humanitarian and development NGOs, which allows us for the first time to map and analyze the allocation of U.S. private aid. We find no support for the common claim that aid NGOs systematically prioritize their organizational self-interest when they allocate private aid, and we find only limited support for the hypothesis that expected aid effectiveness drives aid allocation. By contrast, we find strong support for the argument that the deeply rooted humanitarian discourse within and among aid NGOs drives their aid allocation, consistent with a view of aid NGOs as principled actors and constructivist theories of international relations. Recipients' humanitarian need is substantively and statistically the most significant determinant of U.S. private aid allocation (beyond a regional effect in favor of Latin American countries). Materialist concerns do not crowd out ethical norms among these NGOs.

ID FLIR PERFORMANCE
AB Recent progress, in small infrared detector fabrication, has raised interest in determining the minimum useful detector size. We approach detector size analysis, from an imaging system point of view, with reasonable assumptions for future sensor design. The analysis is a simplified version of the target task performance model using the parameter F lambda/d for generalization. Our figure-of-merit is a system characteristic. The results are easy to use and yield minimum useful detector size of 2 mu m for the mid-wave infrared region (MWIR) and 5 mu m for the long-wave infrared region (LWIR) when coupled with an F/1 optical system under high signal-to-noise ratio conditions. Final size depends upon optical design difficulty, manufacturing constraints, noise equivalent differential temperature, and the operational scenario. For challenging signal-to-noise ratio conditions and more reasonable F/1.2 optics, a 3 mu m MWIR detector and a 6 mu m LWIR detector are recommended. There are many benefits to approaching these detector sizes with low F-number optics. They include lower cost detectors, no need for dual FOV or continuous zoom optics, and no need for dual F-number optics. Our approach provides the smallest volume and lowest weight sensor with maximum range performance. While this paper focuses on infrared design, our approach applies to all imaging sensors.

AB Neutron detectors on spacecraft in the inner heliosphere can observe the low-energy (<30 MeV) solar-flare neutrons that are not easily observable at Earth because they are lost to decay during transit. We present calculations of low-energy neutron production using a computer code incorporating updated neutron-production cross sections for the proton and alpha-particle reactions with heavier elements at all ion energies, especially at low energies (E-ion < 10 MeV nucleon(-1)) most important for producing low-energy neutrons from these reactions. We calculate escaping-neutron spectra and neutron-capture line yields from ions propagating in a magnetic loop with various kinetic-energy spectra. This study provides the basis for planning inner-heliospheric missions having a low-energy neutron detector. The MESSENGER spacecraft orbiting Mercury has such a detector. We conclude that a full understanding of ion acceleration, transport, and interaction at the Sun requires observation of both neutrons and gamma rays with detectors of comparable sensitivity. We find that the neutron-capture line fluence at 1 AU is comparable to the 1-10 MeV neutron fluence at 0.5 AU, and therefore as effective for revealing low-energy ion acceleration. However, as the distance from the Sun to the neutron detector decreases, the tremendous increase of the low-energy neutron flux allows exploration of ion acceleration in weak flares not previously observable and may reveal acceleration at other sites not previously detected where low-energy neutrons could be the only high-energy signature of ion acceleration. Also, a measurement of the low-energy neutron spectrum will provide important information about the accelerated-ion spectrum that is not available from the capture line fluence measurement alone.

AB In this Letter, high-purity, KAuBr4-treated single-wall carbon nanotube (SWCNT) materials are utilised as outer conductors in coaxial cables. The attenuation/length is within Mil-C-17 specification and nearly equivalent to traditional copper outer conductors up to 3 GHz. The improved transmission performance is attributed to higher conductivity and density of the SWCNT network which creates enhanced nanoscale coverage to improve screening. The weight/length which can be achieved with SWCNT outer coaxial cables results in greater than 40% savings compared with conventional coaxial cables while maintaining a flexible cable design.

AB BACKGROUND CONTEXT: Musculoskeletal disorders of the spine in the US military account for the single largest proportion of the absence of sickness causes leading to early termination. We explored if selected psychological and physical factors were associated with poor outcome after episodes of low back pain (LBP).
PURPOSE: To identify clinical, demographic, and psychological factors predictive of work duty status after a complaint of LBP.
STUDY DESIGN: A prospective clinical cohort of US Navy personnel treated for LBP.
PATIENT SAMPLE: Eligible cases were active duty US Navy or Marine Corps personnel presenting to an emergency clinic or primary care clinic with a complaint of LBP, where the index episode of LBP was no more than 12 weeks duration before enrollment.
OUTCOME MEASURES: The subject's work status (full duty, light duty, sick in quarters [SIQ], limited duty, or medically released to full duty) was abstracted from the subject's electronic medical record at approximately 4 weeks and then again 12 weeks after study enrollment. Work status in this study population is assigned by a Navy health-care provider at the time of a clinical visit and based on the health-care provider's determination of medical fitness for duty. This study collapsed work status into two groups, "full duty" (consisting of "full duty" and "medically released to full duty") and "not at full duty" (consisting of "light duty," "SIQ," and "limited duty").
METHODS: Volunteers completed a baseline questionnaire consisting of recommended well-validated measures, including attitudes and beliefs about LBP and work (Fear-Avoidance Beliefs Questionnaire [FABQ] and the Tampa Scale of Kinesiophobia), distress (the Pain Catastrophizing Scale), clinical depression (The Center for Epidemiologic Studies Depression scale), a numeric pain intensity scale, self-perceived disability (Oswestry Disability Index), and general health status (12-Item Short Form Health Survey). Navy health-care providers conducted a back pain-specific medical evaluation. Associations are expressed as multivariate-adjusted prevalence ratios (PRs) estimated using Poisson regression.
RESULTS: Two hundred fifty-three participants were enrolled. Work status outcome was collected for 239 participants. Predictors of "not at full duty" at 4 weeks after enrollment included having back pain for 4 weeks or less before study enrollment (PR, 2.69; 95% CI, 1.21-5.97) and increased FABQ Work subscale score (PR, 1.05; 95% CI, 1.01-1.08). The sole predictor of work status at 12 weeks after enrollment was increased FABQ Physical Activity (FABQ Physical) subscale score (PR=1.14; 95% CI, 1.00-1.30).
CONCLUSIONS: The findings that fear-avoidance beliefs were predictive of subsequent work status among active duty service personnel in this study population (after adjusting for clinical, demographic, and psychological covariates) suggest the clinical utility of addressing these factors during treatment of back pain episodes in the military. These findings reflect the important role that psychological factors may play in the return to work process in an active duty military population. (C) 2012 Elsevier Inc. All rights reserved.

TI The quadratically damped oscillator: A case study of a non-linear
equation of motion
SO AMERICAN JOURNAL OF PHYSICS
LA English
DT Article
AB The equation of motion for a quadratically damped oscillator, where the damping is proportional to the square of the velocity, is a non-linear second-order differential equation. Non-linear equations of motion such as this are seldom addressed in intermediate instruction in classical dynamics; this one is problematic because it cannot be solved in terms of elementary functions. Like all second-order ordinary differential equations, it has a corresponding first-order partial differential equation, whose independent solutions constitute the constants of the motion. These constants readily provide an approximate solution correct to first order in the damping constant. They also reveal that the quadratically damped oscillator is never critically damped or overdamped, and that to first order in the damping constant the oscillation frequency is identical to the natural frequency. The technique described has close ties to standard tools such as integral curves in phase space and phase portraits. (C) 2012 American Association of Physics Teachers.

AB Sand flies are important vectors of cutaneous leishmaniasis, especially along coastal towns of northwestern Libya where an estimated 20,000 cases have occurred from 2004 to 2009. Host-seeking traps are an important tool for sampling sand fly populations and surveying the incidence of Leishmania major and L. tropica within a given population. We evaluated the capture efficiency of CO2-baited BG-Sentinel, Centers for Disease Control and Prevention (CDC) light, CDC ultraviolet light, and nonbaited CO2 CDC light traps in 3 coastal townships during June, August, September, and November 2010. A total of 3,248 sand flies, representing 8 species from 2 genera, were collected; most sand flies were identified as either Phlebotomus papatasi or P. longicuspis. Three of the traps captured significantly more sand flies compared to the BG-Sentinel baited with CO2 (P < 0.001). Three of 456 DNA pools extracted from sand flies were positive for Leishmania DNA, indicating a minimum estimated infection rate of 0.83% and 0.47% for P. papatasi and P. longicuspis, respectively.

AB Mucinous eccrine carcinoma (MEC) is a rare skin cancer of sweat gland origin with a high rate of recurrence. The most common sites are head and neck, with 40% of cancers found on the eyelid. The clinical appearance and differential diagnosis of MEC are highly varied, but histologically it is similar to metastatic carcinomas, specifically breast and colon. A diagnosis of primary MEC always warrants a full systemic workup to ensure that no other malignancy is present. This cancer is known for frequent recurrences, but rarely metastasizes to distant organs. MEC is resistant to both chemotherapy and radiation; surgical excision remains the treatment of choice in most cases. The authors report a unique case of extension of MEC to the lacrimal gland with a brief review of histologic characteristics of this tumor.

AB A roadmap is suggested and demonstrated experimentally for the production of high-energy (>15 MeV) neutrons using short pulse lasers. Investigation with a 3D Monte Carlo model has been employed to quantify the production of energetic neutrons. Numerical simulations have been performed for three nuclear reactions, d(d,n)He-3, Li-7(d,n)Be-8, and Li-7(p,n)Be-7, driven by monoenergetic ion beams. Quantitative estimates for the driver ion beam energy and number have been made and the neutron spectra and yield in the ion propagation direction have been evaluated for various incident ion energies. In order to generate neutron fluence above a detection limit of 10(6) neutrons/sr, either similar to 10(10) protons with energy 20-30 MeV or comparable amount of deuterons with energy 5-10 MeV are required. Experimental verification of the concept with deuterons driven by the Titan laser (peak intensity 2 x 10(19) W/cm(2), pulse duration of 9 ps, wavelength 1.05 mu m, and energy of 360 J) is provided with the generation of neutrons with energy of up to 18 MeV from Li-7(d,n)Be-8 reactions. Future research will focus on optimized schemes for ion acceleration for production of high-energy neutrons, which will involve efficient target design, laser parameter optimization, and converter material.

AB The synthesis of novel zwitterionic polyurethane hydrogels with tunable water uptake via the polymerization of protected carboxybetaine-functionalized diols with polyisocyanate oligomers is presented. Post-polymerization hydrolysis of a diol-segment side chain establishes zwitterionic carboxybetaine functionalities that facilitate water uptake via the enhanced hydration capacities surrounding the opposing charges of the diol component. Tunable hydration of these materials, ranging from 24 to 250% solution uptake (based on the dry polymer weight), is achieved by controlling the structural characteristics of the diol precursor, such as ammonium/carboxylate spacing and ethyl ester hydrolysis conditions (i.e., exposure time to an aqueous base).

AB We report on the gamma-ray observations of giant molecular clouds Orion A and B with the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope. The gamma-ray emission in the energy band between similar to 100 MeV and similar to 100 GeV is predicted to trace the gas mass distribution in the clouds through nuclear interactions between the Galactic cosmic rays (CRs) and interstellar gas. The gamma-ray production cross-section for the nuclear interaction is known to similar to 10% precision which makes the LAT a powerful tool to measure the gas mass column density distribution of molecular clouds for a known CR intensity. We present here such distributions for Orion A and B, and correlate them with those of the velocity-integrated CO intensity (W-CO) at a 1 degrees x 1 degrees pixel level. The correlation is found to be linear over a W-CO range of similar to 10-fold when divided in three regions, suggesting penetration of nuclear CRs to most of the cloud volumes. The W-CO-to-mass conversion factor, X-CO, is found to be similar to 2.3 x 10(20) cm(-2) (K km s(-1))(-1) for the high-longitude part of Orion A (l > 212 degrees), similar to 1.7 times higher than similar to 1.3 x 10(20) found for the rest of Orion A and B. We interpret the apparent high XCO in the high-longitude region of Orion A in the light of recent works proposing a nonlinear relation between H-2 and CO densities in the diffuse molecular gas. W-CO decreases faster than the H-2 column density in the region making the gas "darker" to W-CO.

AB We present Chandra ACIS-I X-ray observations of 0FGL J1311.9-3419 and 0FGL J1653.4-0200, the two brightest high Galactic latitude (|b| > 10 degrees) gamma-ray sources from the three-month Fermi Large Area Telescope (LAT) bright source list that are still unidentified. Both were also detected previously by EGRET, and despite dedicated multi-wavelength follow-up, they are still not associated with established classes of gamma-ray emitters like pulsars or radio-loud active galactic nuclei. X-ray sources found in the ACIS-I fields of view are cataloged, and their basic properties are determined. These are discussed as candidate counterparts to 0FGL J1311.9-3419 and 0FGL J1653.4-0200, with particular emphasis on the brightest of the 9 and 13 Chandra sources detected within the respective Fermi-LAT 95% confidence regions. Further follow-up studies, including optical photometric and spectroscopic observations, are necessary to identify these X-ray candidate counterparts in order to ultimately reveal the nature of these enigmatic gamma-ray objects.

TI MULTIWAVELENGTH OBSERVATIONS OF V2775 Ori, AN OUTBURSTING PROTOSTAR IN L

AB Individual outbursting young stars are important laboratories for studying the physics of episodic accretion and the extent to which this phenomenon can explain the luminosity distribution of protostars. We present new and archival data for V2775 Ori (HOPS 223), a protostar in the L 1641 region of the Orion molecular clouds that was discovered by Caratti o Garatti et al. to have recently undergone an order-of-magnitude increase in luminosity. Our near-infrared spectra of the source have strong blueshifted He I lambda 10830 absorption, strong H2O and CO absorption, and no H I emission, all typical of FU Orionis sources. With data from the Infrared Telescope Facility, the Two Micron All Sky Survey, the Hubble Space Telescope, Spitzer, the Wide-field Infrared Survey Explorer, Herschel, and the Atacama Pathfinder Experiment that span from 1 to 70 mu m pre-outburst and from 1 to 870 mu m post-outburst, we estimate that the outburst began between 2005 April and 2007 March. We also model the pre- and post-outburst spectral energy distributions of the source, finding it to be in the late stages of accreting its envelope with a disk-to-star accretion rate that increased from similar to 2 x 10(-6) M-circle dot yr(-1) to similar to 10(-5) M-circle dot yr(-1) during the outburst. The post-outburst luminosity at the epoch of the FU Orionis-like near-IR spectra is 28 L-circle dot, making V2775 Ori the least luminous documented FU Orionis outburster with a protostellar envelope. The existence of low-luminosity outbursts supports the notion that a range of episiodic accretion phenomena can partially explain the observed spread in protostellar luminosities.

AB We present four new seasons of optical monitoring data and six epochs of X-ray photometry for the doubly imaged lensed quasar Q J0158-4325. The high-amplitude, short-period microlensing variability for which this system is known has historically precluded a time delay measurement by conventional methods. We attempt to circumvent this limitation by the application of a Monte Carlo microlensing analysis technique, but we are only able to prove that the delay must have the expected sign (image A leads image B). Despite our failure to robustly measure the time delay, we successfully model the microlensing at optical and X-ray wavelengths to find a half-light radius for soft X-ray emission log(r(1/2), (X), (soft)/cm) = 14.3(-0.5)(+0.4), an upper limit on the half-light radius for hard X-ray emission log(r(1/2), (X), (hard)/cm) <= 14.6, and a refined estimate of the inclination-corrected scale radius of the optical R-band (rest frame 3100 angstrom) continuum emission region of log(r(s)/cm) = 15.6 +/- 0.3.

AB It is now well established that Kepler's supernova remnant (SNR) is the result of a Type Ia explosion. With an age of 407 yr and an angular diameter of similar to 4', Kepler is estimated to be between 3.0 and 7.0 kpc distant. Unlike other Galactic Type Ia SNRs such as Tycho and SN 1006, and SNR 0509-67.5 in the Large Magellanic Cloud, Kepler shows evidence for a strong circumstellar interaction. A bowshock structure in the north is thought to originate from the motion of a mass-losing system through the interstellar medium prior to the supernova. We present results of hydrodynamical and spectral modeling aimed at constraining the circumstellar environment of the system and the amount of Ni-56 produced in the explosion. Using models that contain either 0.3M(circle dot) (subenergetic) or 1.0M(circle dot) (energetic) of Ni-56, we simulate the interaction between supernova Ia ejecta and various circumstellar density models. Based on dynamical considerations alone, we find that the subenergetic models favor a distance to the SNR of <6.4 kpc, while the model that produces 1M(circle dot) of Ni-56 requires a distance to the SNR of >7 kpc. The X-ray spectrum is consistent with an explosion that produced similar to 1M(circle dot) of Ni-56, ruling out the subenergetic models, and suggesting that Kepler's SNR was an SN 1991T-like event. Additionally, the X-ray spectrum rules out a pure r(-2) wind profile expected from isotropic mass loss up to the time of the supernova. Introducing a small cavity around the progenitor system results in modeled X-ray spectra that are consistent with the observed spectrum. If a wind-shaped circumstellar environment is necessary to explain the dynamics and X-ray emission from the shocked ejecta in Kepler's SNR, then we require that the distance to the remnant be greater than 7 kpc.

AB Biofouling, the attachment and growth of organisms on submerged, man-made surfaces, has plagued ship operators for at least 2500 years. Accumulation of biofouling, including barnacles and other sessile marine invertebrates, increases the frictional resistance of ships' hulls, resulting in an increase in power and in fuel consumption required to make speed. Scientists and engineers recognized over 100 years ago that in order to solve the biofouling problem, a deeper understanding of the biology of the organisms involved, particularly with regard to larval settlement and metamorphosis and adhesives and adhesion, would be required. Barnacles have served as an important tool in pursuing this research. Over the past 20 years, the pace of these studies has accelerated, likely driven by the introduction of environmental regulations banning the most effective biofouling control products from the market. Research has largely focused on larval settlement and metamorphosis, the development of new biocides, and materials/surface science. Increased research has so far, however, failed to result in commercial applications. Two recent successes (medetomidine/Selektope (R), surface-bound noradrenaline) build on our improving understanding of the role of the larval nervous system in mediating settlement and metamorphosis. New findings with regard to the curing of barnacle adhesives may pave the way to additional successes. Although the development of most current biofouling control technologies remains largely uninfluenced by basic research on, for example, the ability of settling larvae to perceive surface cues, or the nature of the interaction between organismal adhesives and the substrate, newly-developed materials can serve as useful probes to further our understanding of these processes.

AB A new wind-input and wind-breaking dissipation for phase-averaged spectral models of wind-generated surface waves is presented. Both are based on recent field observations in Lake George, New South Wales, Australia, at moderate-to-strong wind-wave conditions. The respective parameterizations are built on quantitative measurements and incorporate new observed physical features, which until very recently were missing in source terms employed in operational models. Two novel features of the wind-input source function are those that account for the effects of full airflow separation (and therefore relative reduction of the input at strong wind forcing) and for nonlinear behavior of this term. The breaking term also incorporates two new features evident from observational studies; the dissipation consists of two parts-a strictly local dissipation term and a cumulative term-and there is a threshold for wave breaking, below which no breaking occurs. Four variants of the dissipation term are selected for evaluation, with minimal calibration to each. These four models are evaluated using simple calculations herein. Results are generally favorable. Evaluation for more complex situations will be addressed in a forthcoming paper.

AB The thermospheric wind is a critical geophysical parameter for understanding the behavior of the Earth's upper atmosphere. Global-scale characterization of this parameter is needed to enable improved specification and forecasting of the near space environment. Global-scale measurements of horizontal wind vectors versus altitude have been performed from satellites using a variety of techniques, but the available data are still sparse. To address some of the challenges presented by space-based thermospheric wind measurement, the Doppler Asymmetric Spatial Heterodyne (DASH) technique has recently been developed. Here we present results of a ground-based validation of the DASH technique. The successful validation was performed by conducting collocated ground-based measurements with an instrument that uses the well established Fabry-Perot interferometer technique. Due to cloud cover and a limited observation period, data for only one night of simultaneous observations with minor cloud interference were obtained. The wind velocities observed by the two techniques show good overall agreement, but differences larger than the combined uncertainties are present at times. Contributions to these larger disagreements could be due to cloud interference, the minor differences in the observation geometry, or a non-zero vertical wind. A comparison of this single night of data with the Horizontal Wind Model (HWM07) climatology shows differences of up to about 100 m/s on timescales of less than an hour to several hours.

AB Observations of optical and hydrodynamic processes were made on the open beach on Santa Rosa Island, Florida, in March 1995. This study focuses on the passage of two cold fronts. The observations have been supplemented by a bio-optical model; a suite of hydrodynamic models to simulate coastal flows forced by waves, tides, local wind, and coastal sea level; and a gee-optical model that predicts scattering by mineral particles resuspended by wave action. These models have been used to examine the interaction of atmospheric forcing and hydrodynamics with respect to the observed marine hydrosol. The optical and hydrodynamic measurements, and the model results, have been used to conceive a cold-front regime model of the hydrosol for open beaches in the Gulf of Mexico. The optical environment during the cold front was determined by three hydrosol phases: (1) a prefrontal steady-state hydrosol consisting of fine resuspended mineral particles, phytoplankton cells, organic detritus, and colored dissolved organic matter; (2) a frontal phase dominated by resuspended mineral particles; and (3) a postfrontal hydrosol containing large phytoplankton, detritus, and fine mineral particles. This concept is useful for identifying the physical processes responsible for observed optical properties. It should be applicable to other regions and types of events.

AB Background: Pregnant women commonly present to the Emergency Department (ED) for evaluation during their first trimester. These women have many concerns, one of which is the viability of their pregnancy and the probability of miscarriage. Study Objectives: We sought to determine fetal outcomes of women with an indeterminate ultrasound who present to the ED during the first trimester of pregnancy. Methods: A retrospective analysis of consecutive ED patient encounters from December 2005 to September 2006 was performed to identify patients who were pregnant and who had an indeterminate transvaginal ultrasound performed by an emergency physician or through the Radiology Department during their ED visit. Demographic data, obstetric/gynecologic history, and presenting symptoms were recorded onto a standardized patient chart template designed to be used for any first trimester pregnancy. Outcomes (spontaneous abortion, ectopic pregnancy, and 20-week gestation) were determined via computerized medical records. Results: During the study timeframe, a total of 1164 patients were evaluated in the ED during the first trimester of their pregnancy; 359 patients (30.8%) met inclusion criteria and had a diagnosis of indeterminate ultrasound. Outcome data were obtained for 293 patients. Carrying the pregnancy to >= 20 weeks occurred in 70 patients (23.9%). Spontaneous abortion occurred in 193 women (65.9%), and 30 women (10.2%) were treated for an ectopic pregnancy. Total fetal loss incidence was 89.2% in patients presenting with any vaginal bleeding, compared to 34.7% in patients with pain only. Conclusion: Indeterminate ultrasounds in the setting of first trimester symptomatic pregnancy are indicative of poor fetal outcomes. Vaginal bleeding increased the risk of fetal loss. These data will assist emergency physicians in counseling women in the ED who are found to have an indeterminate ultrasound. Published by Elsevier Inc.

AB Although the effects of combat deployment on posttraumatic stress disorder have been extensively studied, little is known about the effects of combat deployment on depression and anxiety. This study examined the factors associated with anxiety and depression in a sample of 1560 US Marines who were deployed to Iraq and Afghanistan. Eleven demographic and psychosocial factors were studied in relation to depression and anxiety. Five factors emerged as significant in relation to depression: deployment-related stressors, combat exposure, attitudes toward leadership, mild traumatic brain injury symptoms, and marital status. The same factors, with the exception of marital status, emerged as significant in relation to anxiety. Deployment-related stressors had a stronger association with both depression and anxiety than any other variable, including combat exposure. This finding is important because deployment-related stressors are potentially modifiable by the military.

STRUCTURE; COHERENT VORTICES; TURBULENCE; EDDIES; FLUXES; SPACE; MODEL
AB Motivated by the ubiquity of time series in oceanic data, the relative lack of studies of geostrophic turbulence in the frequency domain, and the interest in quantifying the contributions of intrinsic nonlinearities to oceanic frequency spectra, this paper examines the spectra and spectral fluxes of surface oceanic geostrophic flows in the frequency domain. Spectra and spectral fluxes are computed from idealized two-layer quasigeostrophic (QG) turbulence models and realistic ocean general circulation models, as well as from gridded satellite altimeter data. The frequency spectra of the variance of streamfunction (akin to sea surface height) and of geostrophic velocity are qualitatively similar in all of these, with substantial variance extending out to low frequencies. The spectral flux Pi(omega) of kinetic energy in the frequency omega domain for the QG model documents a tendency for nonlinearity to drive energy toward longer periods, in like manner to the inverse cascade toward larger length scales documented in calculations of the spectral flux Pi(k) in the wavenumber k domain. Computations of Pi(omega) in the realistic model also display an "inverse temporal cascade." In satellite altimeter data, some regions are dominated by an inverse temporal cascade, whereas others exhibit a forward temporal cascade. However, calculations performed with temporally and/or spatially filtered output from the models demonstrate that Pi(omega) values are highly susceptible to the smoothing inherent in the construction of gridded altimeter products. Therefore, at present it is difficult to say whether the forward temporal cascades seen in some regions in altimeter data represent physics that is missing in the models studied here or merely sampling artifacts.

AB The present paper examines the temporal evolution of acoustic fields by modeling forward propagation subject to sea surface dynamics with time scales of less than a second to tens of seconds. A time-evolving rough sea surface model is combined with a rough surface formulation of a parabolic equation model for predicting time-varying acoustic fields. Surface waves are generated from surface wave spectra, and stepped in time using a Runge-Kutta integration technique applied to linear evolution equations. This evolving, range-dependent surface information is combined with other environmental parameters and input to the acoustic model, giving an approximation of the time-varying acoustic field. The wide-angle parabolic equation model manages the rough sea surfaces by molding them into the boundary conditions for calculations of the near-surface acoustic field. This merged acoustic model is validated using concurrently-collected acoustic and environmental information, including surface wave spectra. Data to model comparisons demonstrate that the model is able to approximate the ensemble-averaged acoustic intensity at ranges of about a kilometer for acoustic signals of around 15 kHz. Furthermore, the model is shown to capture variations due to surface fluctuations occurring over time scales of less than a second to tens of seconds. (C) 2012 Acoustical Society of America.

DT Article
ID PROPAGATION
AB Following the derivation presented by Press and Ewing [Geophysics 15, 426-446 (1950)], a normal mode solution for the Pekeris waveguide problem with an elastic bottom is outlined. The analytic solution is benchmarked against data collected in an experiment performed at the Naval Research Laboratory [Collis et al., J. Acoust. Soc. Am. 122, 1987-1993 (2007)]. Comparisons reveal a close match between the analytic solution and experimental data. Results are strongly dependent on the accuracy of the horizontal wavenumbers for the modes, and horizontal wavenumber spectra are compared against those from the experimental data.

TI Effects of Reynolds Number and Surface Roughness Magnitude and Location
on Compressor Cascade Performance
SO JOURNAL OF TURBOMACHINERY-TRANSACTIONS OF THE ASME
LA English
DT Article
ID TURBINE; FLOW
AB An experimental investigation has been conducted to characterize the influence of Reynolds number and surface roughness magnitude and location on compressor cascade performance. Flow field surveys have been conducted in a low-speed, linear compressor cascade. Pressure, velocity, and loss have been measured via a five-hole probe, pitot probe, and pressure taps on the blades. Four different roughness magnitudes, R-a values of 0.38 mu m (polished), 1.70 mu m (baseline), 2.03 mu m (rough 1), and 2.89 mu m (rough 2), have been tested. Furthermore, various roughness locations have been examined. In addition to the as manufactured (baseline) and entirely rough blade cases, blades with roughness covering the leading edge, pressure side, and 5%, 20%, 35%, 50%, and 100% of suction side from the leading edge have been studied. All of the tests have been carried out for Reynolds numbers ranging from 300,000 to 640,000. For Reynolds numbers under 500,000, the tested roughnesses do not significantly degrade compressor blade loading or loss. However, loss and blade loading become sensitive to roughness at Reynolds numbers above 550,000. Cascade performance is more sensitive to roughness on the suction side than pressure side. Furthermore, roughness on the aft 2/3 of suction side surface has a greater influence on loss. For a given roughness location, there exists a Reynolds number at which loss begins to significantly increase. Finally, increasing the roughness area on the suction surface from the leading edge reduces the Reynolds number at which the loss begins to increase. [DOI: 10.1115/1.4003821]

TI Thermally reflowed ZEP 520A for gate length reduction and profile
rounding in T-gate fabrication
SO JOURNAL OF VACUUM SCIENCE & TECHNOLOGY B
LA English
DT Article
DE electron resists
ID PHOTORESIST; FREQUENCY; RESIST; HEMTS
AB The characteristics of thermally reflowed ZEP 520A-7 (ZEP), a resist commonly used in electron beam lithography, are presented for use as a gate stem resist layer in T-gate process development. As-developed ZEP lines possess a resist sidewall profile that displays varying amounts of undercut, which are determined by the conditions used to expose the line. The authors find that after thermal reflow, the top of the ZEP profile becomes substantially rounded in shape, mitigating "metal cathedraling" problems, a yield-affecting issue that becomes more pronounced as the gate length is reduced. In addition to profile rounding, a linewidth reduction of over 100 nm is observed, and this process has been used to produce gate lengths in the 30-40 nm range. The changes in feature size and the final profile shape depend on the as-developed sidewall angle. Additionally, the ZEP reflow process saturates after a certain amount of time, so reproducibility is not hindered by a lack of precise control in timing. As larger lines can be used to produce smaller features via reflow, the potential for faster throughput exists due to the use of a higher beam current, which would normally limit the attainable minimum feature size.

AB This study examines the convection and rapid filamentation in Typhoon Sinlaku (2008) using the Naval Research Laboratory (NRL) P-3 aircraft data collected during the Tropical Cyclone Structure 2008 (TCS-08) and The Observing System Research and Predictability Experiment (THORPEX) Pacific Asian Regional Campaign (T-PARC) field experiments. The high-resolution aircraft radar and wind data are used to directly compute the filamentation time, to allow an investigation into the effect of filamentation on convection. During the reintensification stage, some regions of deep convection near the eyewall are found in the vorticity-dominated area where there is little filamentation. In some other parts of the eyewall and the outer spiral rainband region, including areas of upward motion, the filamentation process appears to suppress deep convection. However, the magnitude of the suppression differs greatly in the two regions. In the outer spiral band region, which is about 200 km from the center, the suppression is much more effective, such that the ratio of the deep convective regime occurrence over the stratiform regime varies from around 50% (200%) for filamentation time shorter (longer) than 24 min. In the eyewall cloud region where the conditions are conducive to deep convection, the filamentation effect may be quite limited. While effect of filamentation suppression is only about 10%, it is still systematic and conspicuous for filamentation times shorter than 19 min. The results suggest the possible importance of vortex-scale filamentation dynamics in suppressing deep convection and organizing spiral bands, which may affect the development and evolution of tropical cyclones.

TI Outcomes from a US military neurology and traumatic brain injury
telemedicine program
SO NEUROLOGY
LA English
DT Article
AB Objective: This study evaluated usage of the Army Knowledge Online (AKO) Telemedicine Consultation Program for neurology and traumatic brain injury (TBI) cases in remote overseas areas with limited access to subspecialists. We performed a descriptive analysis of quantity of consults, response times, sites where consults originated, military branches that benefitted, anatomic locations of problems, and diagnoses.
Methods: This was a retrospective analysis that searched electronic databases for neurology consults from October 2006 to December 2010 and TBI consults from March 2008 to December 2010.
Results: A total of 508 consults were received for neurology, and 131 consults involved TBI. For the most part, quantity of consults increased over the years. Meanwhile, response times decreased, with a mean response time of 8 hours, 14 minutes for neurology consults and 2 hours, 44 minutes for TBI consults. Most neurology consults originated in Iraq (67.59%) followed by Afghanistan (16.84%), whereas TBI consults mainly originated from Afghanistan (40.87%) followed by Iraq (33.91%). The most common consultant diagnoses were headaches, including migraines (52.1%), for neurology cases and mild TBI/concussion (52.3%) for TBI cases. In the majority of cases, consultants recommended in-theater management. After receipt of consultant's recommendation, 84 known neurology evacuations were facilitated, and 3 known neurology evacuations were prevented.
Conclusions: E-mail-based neurology and TBI subspecialty teleconsultation is a viable method for overseas providers in remote locations to receive expert recommendations for a range of neurologic conditions. These recommendations can facilitate medically necessary patient evacuations or prevent evacuations for which on-site care is preferable. Neurology (R) 2012;79:1237-1243

TI Analysis of rapid-condensation transient using TRACE
SO NUCLEAR ENGINEERING AND DESIGN
LA English
DT Article
AB A1-Dimensional TRACE model of the UMD-USNA Near One-dimensional Transient Experimental Apparatus (MANOTEA) facility was created and the output compared to facility data. The model over-estimated pressures and temperatures observed in the condenser during the experiment. In addition, the model always predicted that the condenser pipe would fill.
In order to improve the model, a list of the phenomena was generated, and then mapped to TRACE parameters. This exercise was aimed at finding ways to capture the energy partition; and in doing so, prevent the condenser from filling. Over 250 TRACE cases were run, and the effective and physically justifiable parameters were incorporated into a 3-Dimensional Model. The 3-D Model incorporated non-condensable gases, providing a physical mechanism by which transient simulations could terminate smoothly. In addition, A VESSEL component was added to provide a rudimentary means to approximate the energy partition. The 3-D Model generally under-predicted trends observed in the experiments.
Shortcomings in these initial models were discussed. In spite of the need for model improvement, the present work underscored the need to implement a droplet field in TRACE. This droplet field may improve simulations of MANOTEA transients by providing a better means to capture condensation phenomena occurring in the condenser vapor space. Published by Elsevier B.V.

AB Filovirus infection presents many unique challenges to patient management. Currently no approved treatments are available, and the recommendations for supportive care are not evidence based. The austere clinical settings in which patients often present and the sporadic and at times explosive nature of filovirus outbreaks have effectively limited the information available to evaluate potential management strategies. This review will summarize the management approaches used in filovirus outbreaks and provide recommendations for collecting the information necessary for evaluating and potentially improving patient outcomes in the future.

AB The scintillation measured over close-to-ground retro-reflector links can be substantially enhanced due to the correlations experienced by both the direct and reflected echo beams. Experiments were carried out at China Lake, California, over a variety of ranges. The emphasis in this paper is on presenting the data from the 1.1 km retro-reflecting link that was operated for four consecutive days. The dependence of the measured irradiance flux variance on the solar fluence and on the temperature gradient above the ground is presented. The data are consistent with scintillation minima near sunrise and sunset, rising rapidly during the day and saturating at irradiance flux variances of similar to 10. Measured irradiance probability distributions of the retro-reflected beam are compared with standard probability density functions. The ratio of the irradiance flux variances on the retro-reflected to the direct, single-pass case is investigated with two data sets, one from a monostatic system and the other using an off-axis receiver system.

DE Computable general equilibrium; Demographic heterogeneity; Consumer

ID FUTURE CARBON EMISSIONS
AB We describe and evaluate a new method of aggregating heterogeneous households that allows for the representation of changing demographic composition in a multi-sector economic growth model. The method is based on a utility and labor supply calibration that takes into account time variations in demographic characteristics of the population. We test the method using the Population-Environment-Technology (PET) model by comparing energy and emissions projections employing the aggregate representation of households to projections representing different household types explicitly. Results show that the difference between the two approaches in terms of total demand for energy and consumption goods is negligible for a wide range of model parameters. Our approach allows the effects of population aging, urbanization. and other forms of compositional change on energy demand and CO2 emissions to be estimated and compared in a computationally manageable manner using a representative household under assumptions and functional forms that are standard in economic growth models.

TI Stability of a hydrogen molecule in a vacancy of palladium hydrides
SO INTERNATIONAL JOURNAL OF HYDROGEN ENERGY

DT Article
DE Hydrogen molecule; Vacancy; Palladium hydride
ID DEUTERIUM; POINTS
AB We report our ab-initio calculations of energy states of equilibrium H-H separation in a vacancy of palladium and palladium hydrides at a variety of H/Pd loading ratios. In a vacancy of pure palladium, the H-2 molecule has a shallow local energy minimum only in the [001] direction at a separation of 0.96 angstrom and it dissociates into positions near interstitial sites due to its high energy state. Increasing the H/Pd ratio to the beta phase deepens the energy well of the H-2 molecule and results in a shorter H-H separation. At a loading ratio around 1, the H-2 molecule is mostly affected by surrounding hydrogen neighbors and the H-H separation reaches 0.77 angstrom. The H-2 molecule is then fairly stable and its energy state is comparable to that of nearby interstitial sites. Our calculations suggest that the loading ratio of hydrogen in palladium has a significant effect on the stability of the H-2 molecule in the vacancy.

TI A Simple Verification Test for Nonlinear Flow Calculations Around a Ship
Hull Steadily Advancing in Calm Water
SO JOURNAL OF SHIP RESEARCH
LA English
DT Article
DE nonlinear ship waves; CFD verification; analytical relations; wave
profile
AB Simple analytical relations that can readily be applied to verify a critical aspect of numerical predictions of fully nonlinear free-surface flows around ship hulls steadily advancing in calm water are given. The relations do not involve the flow field equations; that is, they are only based on the boundary conditions at the ship hull surface and at the free surface. These boundary conditions have a predominant influence on free-surface flows around advancing ship hulls. The analytical relations are exact for inviscid flows, and can be applied to numerical methods that solve either the Laplace equation (potential-flow methods) or the Euler flow equations (CFD Euler-flow methods). They provide a simple test to verify if numerical predictions given by nonlinear potential-flow or Euler-flow methods correctly satisfy the hull-surface and free-surface boundary conditions along the contact curve between the hull surface and the free surface. The relations might also be used to verify CFD methods that solve the RANS equations if they are applied at the edge of the viscous boundary layer. The analytical test can identify an inconsistency, which might point to a "method issue" related to a feature of a numerical method (e.g., a numerical-differentiation scheme) or an "implementation issue" in the implementation of the method (e.g., a poor discretization). For purposes of illustration, the test is applied to predictions of flows around the Wigley parabolic hull given by two CFD methods that solve the Euler equations with fully nonlinear boundary conditions at the free surface. This illustrative example demonstrates that the test can indeed be useful to identify numerical inaccuracies. The analytical relations can also be used to determine experimental values of the flow velocity at a ship wave profile that correspond to measurements of the wave profile.

AB BACKGROUND Concerns about reproductive health persist among U.S. military members who served in the 19901991 Gulf War. This study explores the long-term impact of 19901991 Gulf War deployment on the prevalence of birth defects among infants of Gulf War veterans. METHODS Health care data from the Department of Defense Birth and Infant Health Registry and demographic and deployment information from the Defense Manpower Data Center were used to identify infants born between 1998 and 2004 to both male and female 19901991 Gulf War veterans. Multivariable logistic regression models estimated the adjusted odds of any birth defect and eight specific birth defects among infants of deployers versus non-deployers. In addition, birth defects were evaluated among infants born to 19901991 Gulf War veterans with deployment-specific exposures. RESULTS Among 178,766 infants identified for these analyses, 3.4% were diagnosed with a birth defect in the first year of life. Compared to infants of non-deployers, infants of deployers were not at increased odds of being diagnosed with a birth defect, or any of eight specific birth defects, in the first year of life. A slightly increased prevalence of birth defects was observed among infants born to men who deployed to the 19901991 Gulf War for 153 to 200 days compared to those who deployed for 1 to 92 days. No other deployment-specific exposures were associated with birth defects in these infants. CONCLUSIONS The 19901991 Gulf War deployers, including those with specific exposures of concern, were not found to be at increased risk for having infants with birth defects 7 to 14 years after deployment.

AB A study of an interesting meteorological episode over the Owens Valley, California, USA during the Terrain-Induced Rotor EXperiment was conducted using a recently adapted statistical interpolation method to retrieve wind-velocity vectors from Doppler lidar data. This vector retrieval method has been adapted from radar data assimilation techniques. Results show that the method allows better preservation of local variations in the flow field than other techniques. In addition, a high resolution Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS (R)) run is used to understand the large-scale flow within the valley and compared with lidar retrievals. Observations from 1030 UTC to 1230 UTC (0230 local time to 0430 local time) on March 27, 2006 are presented. Lidar observations show complex and uncharacteristic flows such as sudden bursts of westerly cross-valley wind mixing with the dominant up-valley wind. Model results from COAMPS and other in-situ instrumentation are used to corroborate and complement these observations. The optimal interpolation technique for Doppler lidar data vector retrieval appears well suited for scenarios with complex spatial variations in the flow field.

Fracture-Dislocations

ID METACARPAL; JOINT; INJURIES; BASE
AB Purpose Ulnar-sided carpometacarpal injuries can be difficult to diagnose radiographically. We hypothesized that the resting position of the normal hand during lateral radiography provides a consistent relationship between the rays and that dorsal subluxation of the metacarpal base in fracture-dislocations increases the angle between the uninjured index and long metacarpals and the injured small metacarpal.
Methods A control group of 100 consecutive patients with normal hand radiographs and a series of 12 patients with known carpometacarpal fracture-dislocations were examined. Angles between the index and small metacarpal shaft (I-S IMA) and between the long and small metacarpal shaft (L-S IMA) were measured on the lateral hand radiograph.
Results In the control group, the mean I-S IMA and L-S IMA were both 6 degrees. In the study group, the mean I-S IMA was 18 degrees, and the mean L-S IMA was 16 degrees. Intraobserver and interobserver reliability was good to excellent for both groups, and a statistical difference existed between the normal and study groups. Based on box-plot analysis of normal and abnormal IMAs, a natural dividing line existed at 10 degrees. With this dividing line, the 1-S IMA had a sensitivity of 92% and a specificity of 81%, and the L-S IMA had a sensitivity of 83% and a specificity of 84%.
Conclusions Both the I-S IMA and the L-S IMA were useful screening measurements on lateral hand radiographs for detection of ulnar-sided carpometacarpal fracture-dislocations. When evaluating posttraumatic ulnar-sided hand pain, advanced imaging should be considered if the I-S IMA or the L-S IMA is greater than 10 degrees. (J Hand Surg 2012;37A:1839-1844.

AB An analysis of the performance of parameterizations for the drag coefficient CD over the ocean is presented. The results were obtained by considering detailed observations from the recent IntOA experiment in which a co-existence of wind sea and swell provides characteristic mixed sea conditions in a wide range of wind speeds. Recent research has advanced our understanding of air-sea fluxes, proposing new functional forms for the drag coefficient, as well as applying wavelength scaling and determining dimensionally consistent expressions for the drag coefficient. Nevertheless, a detailed analysis of the influence of wind sea parameters confirms the need to include the sea state dependence on parameterizing CD for mixed sea conditions. It is also shown that better results are obtained when aerodynamic roughness is considered as a function of wave age and wave steepness, or equivalently if CD is expressed as a function of a characteristic peak frequency defined through the wave momentum spectrum.

AB A new furazan macrocycle, hexakis[1,2,5]oxadiazole[3,4-c:3',4'-e;3 '',4 ''-g:3'",4'"-k:3 '''',4 ''''-m:3 ''''',4 '''''-o][[1,2,9,10]-tetraazacyclohexadecine was synthesized by oxidation of diamino trifurazan with trichloroisocyanuric acid. A macrocyclic product is formed under the reaction conditions. The product displays interesting structural properties within the trifurazan segments of the molecule, where the central rings are rotated nearly 90 degrees out of plane from the outer rings. The macrocycle has also been shown to be a sensitive explosive with sensitivity and power similar to the explosive pentaerythritol tetranitrate (PETN). The chemical and explosive properties of this new macrocycle are described in this letter.
