TI Sexual Health Competence of International Medical Graduate Psychiatric Residents in the United States SO ACADEMIC PSYCHIATRY LA English DT Article ID UNANNOUNCED STANDARDIZED PATIENTS; EROTIC PLASTICITY; HONG-KONG; ATTITUDES; BEHAVIORS; STUDENTS; CULTURE; PHYSICIANS; KNOWLEDGE; DYSFUNCTION AB Objective: Currently in the United States, more than one in three psychiatric residents are international medical graduates (IMGs). In light of forecasts of physician shortages, this proportion is likely to continue growing. Although central to psychiatric care, sexual health competence levels of IMGs may be lower than those of U. S. graduates. Methods: The authors conducted a nonsystematic review of the literature and online data to establish the learning needs of IMGs in this area. Results: Data on five areas are summarized: demographic and sociocultural data of IMGs in the United States; the need for sexual medicine competence for practicing psychiatrists; how sexual health is currently taught in foreign medical schools; attitudes toward sexuality and sexual problems among physicians and patients of different cultures; and the management of sexual issues, including sexual boundaries, by IMGs. Conclusion: The authors found evidence suggesting that IMGs from areas most culturally dissimilar to the United States are likely to benefit from sexual medicine curricula in the context of cultural competence training. The diversity and resilience of IMGs are emphasized. Implications for immediate training and future research are outlined.

TI Thread-Management Techniques to Maximize Efficiency in Multicore and Simultaneous Multithreaded Microprocessors SO ACM TRANSACTIONS ON ARCHITECTURE AND CODE OPTIMIZATION LA English DT Article DE Design; Performance; Meeting point thread characterization; critical threads; thread delaying; thread balancing; multi-threaded application; microarchitecture; low-power; energy-aware AB We provide an analysis of thread-management techniques that increase performance or reduce energy in multicore and Simultaneous Multithreaded (SMT) cores. Thread delaying reduces energy consumption by running the core containing the critical thread at maximum frequency while scaling down the frequency and voltage of the cores containing noncritical threads. In this article, we provide an insightful breakdown of thread delaying on a simulated multi-core microprocessor. Thread balancing improves overall performance by giving higher priority to the critical thread in the issue queue of an SMT core. We provide a detailed breakdown of performance results for thread-balancing, identifying performance benefits and limitations. For those benchmarks where a performance benefit is not possible, we introduce a novel thread-balancing mechanism on an SMT core that can reduce energy consumption. We have performed a detailed study on an Intel microprocessor simulator running parallel applications. Thread delaying can reduce energy consumption by 4% to 44% with negligible performance loss. Thread balancing can increase performance by 20% or can reduce energy consumption by 23%. C1 [Rakvic, R.] USN Acad, Annapolis, MD 21402 USA.

TI Quantum Dot Peptide Biosensors for Monitoring Caspase 3 Proteolysis and Calcium Ions SO ACS NANO LA English DT Article DE quantum dot; nanocrystal; biosensor; protease; calcium; FRET; indicator; caspase 3; fluorescence; energy transfer; dye ID RESONANCE ENERGY-TRANSFER; CLICK CHEMISTRY; GOLD NANOPARTICLES; TERMINAL ALKYNES; DRUG-DELIVERY; PROTEINS; APOPTOSIS; NANOCRYSTALS; NANOSENSOR; DIAGNOSIS AB The nanoscale size and unique optical properties of semiconductor quantum dots (QDs) have made them attractive as central photoluminescent scaffolds for a variety of biosensing platforms. In this report we functionalize QDs with dye-labeled peptides using two different linkage chemistries to yield Forster resonance energy transfer (FRET)-based sensors capable of monitoring either enzymatic activity or ionic presence. The first sensor targets the proteolytic activity of caspase 3, a key downstream effector of apoptosis. This QD conjugate utilized carbodiimide chemistry to covalently link dye-labeled peptide substrates to the terminal carboxyl groups on the QD's surface hydrophilic ligands in a quantitative manner. Caspase 3 cleaved the peptide substrate and disrupted QD donor-dye acceptor FRET providing signal transduction of enzymatic activity and allowing derivation of relevant Michaelis-Menten kinetic descriptors. The second sensor was designed to monitor Ca2+ ions that are ubiquitous in many biological processes. For this sensor, Cu+-catalyzed [3 + 2] azide-alkyne cycloaddition was exploited to attach a recently developed azide-functionalized CalciumRuby-CI indicator dye to a cognate alkyne group present on the terminus of a modified peptide. The labeled peptide also expressed a polyhistidine sequence, which facilitated its subsequent metal-affinity coordination to the QD surface establishing the final FRET sensing construct. Adding exogenous Ca2+ to the sensor solution increased the dyes fluorescence, altering the donor-acceptor emission ratio and manifested a dissociation constant similar to that of the native dye. These results highlight the potential for combining peptides with QDs using different chemistries to create sensors for monitoring chemical compounds and biological processes.

Precipitation of Al(3)Sc (L1(2)) commences between 200 and 250 degrees C in Al-0.1Sc, reaching a 670 MPa peak microhardness at 325 degrees C. For Al-0.1Zr, precipitation of Al(3)Zr (L1(2)) initiates between 350 and 375 degrees C, resulting in a 420 MPa peak microhardness at 425-450 degrees C. A pronounced synergistic effect is observed when both Sc and Zr are present. Above 325 degrees C, Zr additions provide a secondary strength increase from the precipitation of Zr-enriched outer shells onto the Al(3)Sc precipitates, leading to a peak microhardness of 780 MPa at 400 degrees C for Al-0.1Sc-0.1Zr. Compositions, radii, volume fractions and number densities of the Al(3)(Sc(1-x)Zr(x)) precipitates are measured directly using atom-probe tomography. This information is used to quantify the observed strengthening increments, attributed to dislocation shearing of the Al(3)(Sc(1-x)Zr(x)) precipitates.

TI Three-dimensional analysis of grain topology and interface curvature in a beta-titanium alloy SO ACTA MATERIALIA LA English DT Article DE 3-D serial sectioning; Grain growth; Grain morphology ID COMPUTER-SIMULATION; FIELD MODEL; GROWTH LAW; DIMENSIONS AB While considerable efforts have been made to model the effects of grain coarsening, there has been little experimental verification of these models. Using serial sectioning techniques, the full 3-D morphology of 2098 beta-titanium grains in Ti-21S are analyzed and directly compared to grain coarsening theories. The experimental grain size distribution and the distribution in the number of grain faces are shown to have a close comparison to the predictions of the steady-state size distribution from a number of simulations and analytical theories. The geometric factor of the growth rates is determined by measuring the mean curvature of the grain faces. It is found that, on average, the grains with an average of 15.5 faces have a zero integral mean curvature of the grain faces, higher than the predicted value of 13.4 faces. This difference is suggested to be due to the non-random nearest-neighbor effects within the grain network. Published by Elsevier Ltd. on behalf of Acta Materialia Inc. C1 [Rowenhorst, D.

Five factors were associated with antisocial behavior in multivariate analyses: post-traumatic stress disorder (PTSD) symptoms, deployment-related stressors, combat exposure, younger age, and being divorced. PTSD symptoms had a stronger association with antisocial behavior than any other variable. A unique and important finding of this study was the association between deployment-related stressors and a higher incidence of antisocial behavior. Because deployment-related stressors are potentially modifiable, the military may be able to address them in concrete ways such as by shortening deployments and improving communication with home.

TI Injury Reduction Effectiveness of Assigning Running Shoes Based on Plantar Shape in Marine Corps Basic Training SO AMERICAN JOURNAL OF SPORTS MEDICINE LA English DT Article DE physical fitness; physical activity; tobacco use; prior injury; demographics; menstrual dysfunction ID LOWER-EXTREMITY INJURY; MEDICAL SURVEILLANCE; US NAVY; MILITARY; EPIDEMIOLOGY; PREVENTION; RECOMMENDATIONS; RECRUITS; RATES; ARMY AB Background: Shoe manufacturers market motion control, stability, and cushioned shoes for plantar shapes defined as low, normal, and high, respectively. This assignment procedure is presumed to reduce injuries by compensating for differences in running mechanics. Hypothesis: Assigning running shoes based on plantar shape will not reduce injury risk in Marine Corps basic training. Study Design: Randomized controlled clinical trial; Level of evidence, 1. Methods: After foot examinations, Marine Corps recruits in an experimental group (E: 408 men, 314 women) were provided motion control, stability, or cushioned shoes for plantar shapes indicative of low, medium, or high arches, respectively. A control group (C: 432 men, 257 women) received a stability shoe regardless of plantar shape. Injuries during the 12 weeks of training were determined from outpatient visits obtained from the Defense Medical Surveillance System. Other known injury risk factors (eg, fitness, smoking, prior physical activity) were obtained from a questionnaire, existing databases, or the training units. Results: Cox regression indicated little difference in injury risk between the E and C groups among men (hazard ratio [E/C] = 1.01; 95% confidence interval, 0.82-1.24) or women (hazard ratio [E/C] = 0.88; 95% confidence interval, 0.70-1.10). Conclusion: This prospective study demonstrated that assigning shoes based on the shape of the plantar foot surface had little influence on injuries even after considering other injury risk factors.

TI Llama-derived single-domain antibodies for the detection of botulinum A neurotoxin SO ANALYTICAL AND BIOANALYTICAL CHEMISTRY LA English DT Article DE Single-domain antibody; Botulinum neurotoxin; Camelid; Immunoassay ID TOXIN; FRAGMENTS; ASSAY; STABILITY; BIOSENSOR; FOODS AB Single-domain antibodies (sdAb) specific for botulinum neurotoxin serotype A (BoNT A) were selected from an immune llama phage display library derived from a llama that was immunized with BoNT A toxoid. The constructed phage library was panned using two methods: panning on plates coated with BoNT A toxoid (BoNT ATd) and BoNT A complex toxoid (BoNT Ac Td) and panning on microspheres coupled to BoNT A Td and BoNT A toxin (BoNT A Tx). Both panning methods selected for binders that had identical sequences, suggesting that panning on toxoided material may be as effective as panning on bead-immobilized toxin for isolating specific binders. All of the isolated binders tested were observed to recognize bead-immobilized BoNT A Tx in direct binding assays, and showed very little cross-reactivity towards other BoNT serotypes and unrelated protein. Sandwich assays that incorporated selected sdAb as capture and tracer elements demonstrated that all of the sdAb were able to recognize soluble ("live") BoNT A Tx and BoNT Ac Tx with virtually no cross-reactivity with other BoNT serotypes. The isolated sdAb did not exhibit the high degree of thermal stability often associated with these reagents; after the first heating cycle most of the binding activity was lost, but the portion of the protein that did refold and recover antigen-binding activity showed only minimal loss on subsequent heating and cooling cycles. The binding kinetics of selected binders, assessed by both an equilibrium fluid array assay as well as surface plasmon resonance (SPR) using toxoided material, gave dissociation constants (K(D)) in the range 2.2 x 10(-11) to 1.6 x 10(-10) M. These high-affinity binders may prove beneficial to the development of recombinant reagents for the rapid detection of BoNT A, particularly in field screening and monitoring applications.

TI Binding Kinetics of Antiricin Single Domain Antibodies and Improved Detection Using a B Chain Specific Binder SO ANALYTICAL CHEMISTRY LA English DT Article ID RICIN; LIBRARY; PLANTS; TOXINS; ABRIN AB Single domain antibodies are the recombinantly expressed binding fragments derived from heavy chain antibodies found in camels and llamas. These unique binding elements offer many desirable properties such as their small size (similar to 15 kDa) and thermal stability, which makes them attractive alternatives to conventional monoclonal antibodies. We created a phage display library from llamas immunized with ricin toxoid and selected a number of single domain antibodies. Phage selected on ricin were found to bind to either ricin A chain or the intact molecule; no ricin B chain binders were identified. By panning on B chain, we identified binders and have characterized their binding to the ricin B chain. While they have a poorer affinity than the previously described A chain binders, it was found that they performed dramatically better as capture reagents for the detection of ricin, providing a limit of detection in enzyme linked immunosorbent assay (ELISA) below 100 pg/mL and excellent specificity for ricin versus the highly related RCA 120 (1 to 10 000). We also reevaluated the previously isolated antiricin single domain antibody binding kinetics using surface plasmon resonance and found their K(d)s matched closely to those previously obtained under equilibrium binding conditions measured using the Luminex flow cytometer.

DISCOVERY OF NEW PROPER MOTION STARS IN UCAC3 WITH 0.'' 40 yr(-1) > mu >= 0.'' 18 yr(-1) BETWEEN DECLINATIONS-90 degrees AND-47 degrees SO ASTRONOMICAL JOURNAL LA English DT Article DE astrometry; solar neighborhood; stars: distances; stars: statistics; surveys ID SUPERCOSMOS SKY SURVEY; SOLAR NEIGHBORHOOD; NEARBY STARS; SOUTHERN SKY; CATALOG; -90-DEGREES; -47-DEGREES; PHOTOMETRY; DWARFS AB This paper presents 442 new proper motion stellar systems in the southern sky between declinations -90 degrees and -47 degrees with 0.'' 40 yr(-1) > mu >= 0.'' 18 yr(-1). These systems constitute a 25.3% increase in new systems for the same region of the sky covered by previous SuperCOSMOS RECONS (SCR) searches that used Schmidt plates as the primary source of discovery. Among the new systems are 25 multiples, plus an additional 7 new common proper motion (CPM) companions to previously known primaries. All stars have been discovered using the third U. S. Naval Observatory (USNO) CCD Astrograph Catalog (UCAC3). A comparison of the UCAC3 proper motions to those from the Hipparcos, Tycho-2, Southern Proper Motion (SPM4), and SuperCOSMOS efforts is presented and shows that UCAC3 provides similar values and precision to the first three surveys. The comparison between UCAC3 and SuperCOSMOS indicates that proper motions in R. A. are systematically shifted in the SuperCOSMOS data but are consistent in decl. data, while overall showing a significantly higher scatter. Distance estimates are derived for stars having SuperCOSMOS Sky Survey BJ, R59F, and IIVN plate magnitudes and Two-Micron All Sky Survey infrared photometry. We find 15 systems estimated to be within 25 pc, including UPM 1710-5300 our closest new discovery estimated at 13.5 pc. Such new discoveries suggest that more nearby stars are yet to be found in these slower proper motion regimes, indicating that more work is needed to develop a complete map of the solar neighborhood.

TI On the origin of [NeII] 12.81 mu m emission from pre-main sequence stars: Disks, jets, and accretion SO ASTRONOMY & ASTROPHYSICS LA English DT Article DE stars: formation; stars: pre-main sequence; protoplanetary disks ID T-TAURI STARS; YOUNG STELLAR OBJECTS; IRRADIATED PROTOPLANETARY DISKS; HIGH-RESOLUTION SPECTROSCOPY; MOLECULAR-HYDROGEN EMISSION; CO FUNDAMENTAL EMISSION; SPITZER-SPACE-TELESCOPE; STRUCTURE LINE EMISSION; NEWTON EXTENDED SURVEY; PHOTON IMAGING CAMERA AB Context. Extreme-ultraviolet (EUV) and X-ray photons from classical T Tauri stars are powerful ionization and heating agents that drive disk chemistry, disk instabilities, and photoevaporative flows. The mid-infrared fine-structure line of [Ne II] at 12.81 mu m has been proposed to trace gas in disk surface layers heated and ionized by stellar X-ray and EUV radiation. Aims. We aim at locating the origin of [Ne II] line emission in circumstellar environments by studying distributions of [Ne II] emission and correlating the inferred [Ne II] luminosities, L([Ne II]), with stellar and circumstellar disk parameters. Methods. We have conducted a study of [Ne II] line emission based on a sample of 92 pre-main sequence stars mostly belonging to the infrared Class II, but including 13 accreting transition disk objects, and also 14 objects that drive known jets and outflows. Results. We find several significant correlations between L([Ne II]) and stellar parameters, in particular L(X) and the wind mass loss rate,. (M) over dot(loss). Most correlations are, however, strongly dominated by systematic scatter of unknown origin. While there is a positive correlation between L([Ne II]) and L(X), the stellar mass accretion rate,. (M) over dot(acc), induces a correlation only if we combine the largely different subsets of jet sources and stars without jets. Our results indeed suggest that L([Ne II]) is bi-modally distributed, with separate distributions for the two subsamples. The jet sources show systematically higher L([Ne II]), by 1-2 orders of magnitude with respect to objects without jets. Jet-driving stars also tend to show higher mass accretion rates. We therefore hypothesize that the trend with. (M) over dot(acc) only reflects a trend with (M) over dot(loss) that is more physically relevant for [Ne II] emission. Conclusions. The [Ne II] luminosities measured for objects without known outflows and jets are found to agree with simplified calculations of [Ne II] emission from disk surface layers if the measured stellar X-rays are responsible for heating and ionizing the gas. The large scatter in L([Ne II]) may be introduced by variations of disk properties and the irradiation spectrum, as previously suggested. If these additional factors can be sufficiently well constrained, then the [Ne II] 12.81 mu m line should be an important diagnostic for disk surface ionization and heating, at least in the inner disk region. This applies in particular to transition disks also included in our sample. The systematically enhanced [Ne II] flux from jet sources clearly suggests a role for the jets themselves, as previously demonstrated by a spatially resolved observation of the outflow system in the T Tau triple.

TI TANAMI: tracking active galactic nuclei with austral milliarcsecond interferometry I. First-epoch 8.4GHz images SO ASTRONOMY & ASTROPHYSICS LA English DT Article DE galaxies: active; galaxies: jets; galaxies: nuclei; gamma rays: observations; quasars: general ID SOUTHERN RADIO-SOURCES; GAMMA-RAY EMISSION; GIGAHERTZ-PEAKED SPECTRUM; LACERTAE OBJECT PKS-2005-489; HEMISPHERE ICRF SOURCES; PARSEC-SCALE STRUCTURE; LARGE-AREA TELESCOPE; BLAZAR PKS 0537-441; VLBI OBSERVATIONS; EGRET OBSERVATIONS AB Context. A number of theoretical models vie to explain the gamma-ray emission from active galactic nuclei (AGN). This was a key discovery of EGRET. With its broader energy coverage, higher resolution, wider field of view and greater sensitivity, the Large Area Telescope (LAT) of the Fermi Gamma-ray Space Telescope is dramatically increasing our knowledge of AGN gamma-ray emission. However, discriminating between competing theoretical models requires quasi-simultaneous observations across the electromagnetic spectrum. By resolving the powerful parsec-scale relativistic outflows in extragalactic jets and thereby allowing us to measure critical physical properties, Very Long Baseline Interferometry observations are crucial to understanding the physics of extragalactic gamma-ray objects. Aims. We introduce the TANAMI program (Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry) which is monitoring an initial sample of 43 extragalactic jets located south of -30 degrees declination at 8.4GHz and 22GHz since 2007. All aspects of the program are discussed. First epoch results at 8.4GHz are presented along with physical parameters derived therefrom. Methods. These observations were made during 2007/2008 using the telescopes of the Australian Long Baseline Array in conjunction with Hartebeesthoek in South Africa. These data were correlated at the Swinburne University correlator. Results. We present first epoch images for 43 sources, some observed for the first time at milliarcsecond resolution. Parameters of these images as well as physical parameters derived from them are also presented and discussed. These and subsequent images from the TANAMI survey are available at http://pulsar.sternwarte.uni-erlangen.de/tanami/. Conclusions. We obtain reliable, high dynamic range images of the southern hemisphere AGN. All the quasars and BL Lac objects in the sample have a single-sided radio morphology. Galaxies are either double-sided, single-sided or irregular. About 28% of the TANAMI sample has been detected by LAT during its first three months of operations. Initial analysis suggests that when galaxies are excluded, sources detected by LAT have larger opening angles than those not detected by LAT. Brightness temperatures of LAT detections and non-detections seem to have similar distributions. The redshift distributions of the TANAMI sample and sub-samples are similar to those seen for the bright gamma-ray AGN seen by LAT and EGRET but none of the sources with a redshift above 1.8 have been detected by LAT.

TI Testing magnetofrictional extrapolation with the Titov-Demoulin model of solar active regions SO ASTRONOMY & ASTROPHYSICS LA English DT Article DE magnetic fields; Sun: corona; Sun: surface magnetism ID CORONAL MAGNETIC-FIELD; FORCE-FREE FIELD; VECTOR MAGNETOGRAPH DATA; QUASI-SEPARATRIX LAYERS; HYPERBOLIC FLUX TUBES; NON-CONSTANT-ALPHA; KINK INSTABILITY; MASS EJECTIONS; ROPE; EQUILIBRIUM AB We examine the nonlinear magnetofrictional extrapolation scheme using the solar active region model by Titov and Demoulin as test field. This model consists of an arched, line-tied current channel held in force-free equilibrium by the potential field of a bipolar flux distribution in the bottom boundary. A modified version with a parabolic current density profile is employed here. We find that the equilibrium is reconstructed with very high accuracy in a representative range of parameter space, using only the vector field in the bottom boundary as input. Structural features formed in the interface between the flux rope and the surrounding arcade - "hyperbolic flux tube" and "bald patch separatrix surface" - are reliably reproduced, as are the flux rope twist and the energy and helicity of the configuration. This demonstrates that force-free fields containing these basic structural elements of solar active regions can be obtained by extrapolation. The influence of the chosen initial condition on the accuracy of reconstruction is also addressed, confirming that the initial field that best matches the external potential field of the model quite naturally leads to the best reconstruction. Extrapolating the magnetogram of a Titov-Demoulin equilibrium in the unstable range of parameter space yields a sequence of two opposing evolutionary phases, which clearly indicate the unstable nature of the configuration: a partial buildup of the flux rope with rising free energy is followed by destruction of the rope, losing most of the free energy.

We report results obtained from the analysis of 13 months of LAT data for three of these pulsars (PSR J1057-5226, PSR J1709-4429, and PSR 11952+3252) each of which had some unique feature among the EGRET pulsars. The excellent sensitivity of LAT allows more detailed analysis of the evolution of the pulse profile with energy and also of the variation of the spectral shape with phase. We measure the cutoff energy of the pulsed emission from these pulsars for the first time and provide a more complete picture of the emission mechanism. The results confirm some, but not all, of the features seen in the EGRET data. C1 [Ardo, A. A.; Chekhtman, A. .; Cheung, C. C.; Dermer, C. D.; Grove, J. E.; Johnson, W. N.; Makeev, A.; Strickman, M.

In order to search for new young stellar objects (YSOs), we have observed this region in seven mid- and far-infrared bands using the Spitzer Space Telescope and in four bands in the optical using the U. S. Naval Observatory 40 inch telescope. We find infrared excesses in four of the six previously known T Tauri stars in our combined infrared maps, and we find six entirely new candidate YSOs, one of which may be an edge-on disk. Most of the YSOs seen in the infrared are Class II objects, and they are all in the "head" of the nebula, within the most massive molecular cloud of the region. C1 [Guieu, S.; Rebull, L.

TI FERMI-LAT OBSERVATIONS OF THE GEMINGA PULSAR SO ASTROPHYSICAL JOURNAL LA English DT Article DE gamma rays: stars; pulsars: general; pulsars: individual (PSR J0633+1746, Geminga) ID LARGE-AREA TELESCOPE; GAMMA-RAY PULSARS; PHASE-RESOLVED SPECTRA; SPACE-TELESCOPE; VELA PULSAR; OUTER MAGNETOSPHERE; OPTICAL COUNTERPART; WIND TORI; RADIATION; EMISSION AB We report on the Fermi-LAT observations of the Geminga pulsar, the second brightest non-variable GeV source in the gamma-ray sky and the first example of a radio-quiet gamma-ray pulsar. The observations cover one year, from the launch of the Fermi satellite through 2009 June 15. A data sample of over 60,000 photons enabled us to build a timing solution based solely on gamma-rays. Timing analysis shows two prominent peaks, separated by Delta phi = 0.497 +/- 0.004 in phase, which narrow with increasing energy. Pulsed gamma-rays are observed beyond 18 GeV, precluding emission below 2.7 stellar radii because of magnetic absorption. The phase-averaged spectrum was fitted with a power law with exponential cutoff of spectral index Gamma = (1.30 +/- 0.01 +/- 0.04), cutoff energy E-0 = (2.46 +/- 0.04 +/- 0.17) GeV, and an integral photon flux above 0.1 GeV of (4.14 +/- 0.02 +/- 0.32) x 10(-6) cm(-2) s(-1). The first uncertainties are statistical and the second ones are systematic. The phase-resolved spectroscopy shows a clear evolution of the spectral parameters, with the spectral index reaching a minimum value just before the leading peak and the cutoff energy having maxima around the peaks. The phase-resolved spectroscopy reveals that pulsar emission is present at all rotational phases. The spectral shape, broad pulse profile, and maximum photon energy favor the outer magnetospheric emission scenarios. C1 [Abdo, A. A.; Chekhtman, A.; Cheung, C. C.; Dermer, C. D.; Grove, J.

TI THE FERMI-LAT HIGH-LATITUDE SURVEY: SOURCE COUNT DISTRIBUTIONS AND THE ORIGIN OF THE EXTRAGALACTIC DIFFUSE BACKGROUND SO ASTROPHYSICAL JOURNAL LA English DT Article DE cosmology: observations; diffuse radiation; galaxies: active; galaxies: jets; gamma rays: diffuse background; surveys ID LARGE-AREA TELESCOPE; ACTIVE GALACTIC NUCLEI; GAMMA-RAY EMISSION; N-LOG S; LUMINOSITY FUNCTION; SPACE-TELESCOPE; DARK-MATTER; COSMIC-RAYS; BLAZARS; GALAXIES AB This is the first of a series of papers aimed at characterizing the populations detected in the high-latitude sky of the Fermi-LAT survey. In this work, we focus on the intrinsic spectral and flux properties of the source sample. We show that when selection effects are properly taken into account, Fermi sources are on average steeper than previously found (e.g., in the bright source list) with an average photon index of 2.40 +/- 0.02 over the entire 0.1-100 GeV energy band. We confirm that flat spectrum radio quasars have steeper spectra than BL Lacertae objects with an average index of 2.48 +/- 0.02 versus 2.18 +/- 0.02. Using several methods, we build the deepest source count distribution at GeV energies, deriving that the intrinsic source (i.e., blazar) surface density at F-100 >= 10(-9) ph cm(2) s(-1) is 0.12(-0.02)(+0.03) deg(-2). The integration of the source count distribution yields that point sources contribute 16(+/- 1.8)% (+/- 7% systematic uncertainty) of the GeV isotropic diffuse background. At the fluxes currently reached by LAT, we can rule out the hypothesis that pointlike sources (i.e., blazars) produce a larger fraction of the diffuse emission. C1 [Abdo, A.

DETECTION RATES SO ASTROPHYSICAL JOURNAL LA English DT Article DE astrochemistry; protoplanetary disks; stars: pre-main sequence ID T-TAURI STARS; MAIN-SEQUENCE STARS; INTERMEDIATE-MASS STARS; PLANET-FORMING REGION; YOUNG STELLAR OBJECTS; HERBIG AE/BE STARS; H-ALPHA-EMISSION; CIRCUMSTELLAR DISKS; SPECTROSCOPIC BINARIES; GAS TEMPERATURE AB We present a Spitzer InfraRed Spectrometer search for 10-36 mu m molecular emission from a large sample of protoplanetary disks, including lines from H(2)O, OH, C(2)H(2), HCN, and CO(2). This paper describes the sample and data processing and derives the detection rate of mid-infrared molecular emission as a function of stellar mass. The sample covers a range of spectral type from early M to A, and is supplemented by archival spectra of disks around A and B stars. It is drawn from a variety of nearby star-forming regions, including Ophiuchus, Lupus, and Chamaeleon. Spectra showing strong emission lines are used to identify which lines are the best tracers of various physical and chemical conditions within the disks. In total, we identify 22 T Tauri stars with strong mid-infrared H(2)O emission. Integrated water line luminosities, where water vapor is detected, range from 5 x 10(-4) to 9 x 10(-3) L(circle dot), likely making water the dominant line coolant of inner disk surfaces in classical T Tauri stars. None of the five transitional disks in the sample show detectable gaseous molecular emission with Spitzer upper limits at the 1% level in terms of line-to-continuum ratios (apart from H(2)), but the sample is too small to conclude whether this is a general property of transitional disks. We find a strong dependence on detection rate with spectral type; no disks around our sample of 25 A and B stars were found to exhibit water emission, down to 1%-2% line-to-continuum ratios, in the mid-infrared, while more than half of disks around late-type stars (M-G) show sufficiently intense water emission to be detected by Spitzer, with a detection rate approaching 2/3 for disks around K stars. Some Herbig Ae/Be stars show tentative H(2)O/OH emission features beyond 20 mu m at the 1%-2% level, however, and one of them shows CO(2) in emission. We argue that the observed differences between T Tauri disks and Herbig Ac/Be disks are due to a difference in excitation and/or chemistry depending on spectral type and suggest that photochemistry may be playing an important role in the observable characteristics of mid-infrared molecular line emission from protoplanetary disks.

TI FERMI LARGE AREA TELESCOPE OBSERVATIONS OF MISALIGNED ACTIVE GALACTIC NUCLEI SO ASTROPHYSICAL JOURNAL LA English DT Article DE galaxies: active; galaxies: jets; gamma rays: general ID GAMMA-RAY EMISSION; I RADIO GALAXIES; MOLONGLO-SOUTHERN-4-JY SAMPLE MS4; RELATIVISTIC JETS; M87 JET; SPACE-TELESCOPE; HIGH-RESOLUTION; LAC OBJECTS; SCALE JETS; HOT-SPOTS AB Analysis is presented for 15 months of data taken with the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope for 11 non-blazar active galactic nuclei (AGNs), including seven FRI radio galaxies and four FRII radio sources consisting of two FRII radio galaxies and two steep spectrum radio quasars. The broad line FRI radio galaxy 3C 120 is reported here as a gamma-ray source for the first time. The analysis is based on directional associations of LAT sources with radio sources in the 3CR, 3CRR, and MS4 (collectively referred to as 3C-MS) catalogs. Seven of the eleven LAT sources associated with 3C-MS radio sources have spectral indices larger than 2.3 and, except for the FRI radio galaxy NGC 1275 that shows possible spectral curvature, are well described by a power law. No evidence for time variability is found for any sources other than NGC 1275. The gamma-ray luminosities of FRI radio galaxies are significantly smaller than those of the BL Lac objects detected by the LAT, whereas the gamma-ray luminosities of the FRII sources are quite similar to those of FSRQs, which could reflect different beaming factors for the gamma-ray emission. A core dominance (CD) study of the 3CRR sample indicates that sources closer to the jet axis are preferentially detected with the Fermi LAT, insofar as the gamma-ray-detected misaligned AGNs have larger CD at a given average radio flux. The results are discussed in view of the AGN unification scenario. C1 [Grandi, P.; Malaguti, G.; Torresi, E.] INAF IASF Bologna, I-40129 Bologna, Italy. [Abdo, A. A.; Chekhtman, A.; Cheung, C.

TI GALEX AND PAN-STARRS1 DISCOVERY OF SN IIP 2010aq: THE FIRST FEW DAYS AFTER SHOCK BREAKOUT IN A RED SUPERGIANT STAR SO ASTROPHYSICAL JOURNAL LETTERS LA English DT Article DE supernovae: individual (SN 2010aq); surveys; ultraviolet: general ID CORE-COLLAPSE SUPERNOVAE; FORMING GALAXIES; P SUPERNOVAE; LIGHT CURVES; GRB-060218; SPECTROSCOPY; PROGENITORS; ABUNDANCES; EMISSION; PLATEAU AB We present the early UV and optical light curve of Type IIP supernova (SN) 2010aq at z = 0.0862, and compare it to analytical models for thermal emission following SN shock breakout in a red supergiant star. SN 2010aq was discovered in joint monitoring between the Galaxy Evolution Explorer (GALEX) Time Domain Survey (TDS) in the NUV and the Pan-STARRS1 Medium Deep Survey (PS1 MDS) in the g, r, i, and z bands. The GALEX and Pan-STARRS1 observations detect the SN less than 1 day after the shock breakout, measure a diluted blackbody temperature of 31,000 +/- 6000 K 1 day later, and follow the rise in the UV/optical light curve over the next 2 days caused by the expansion and cooling of the SN ejecta. The high signal-to-noise ratio of the simultaneous UV and optical photometry allows us to fit for a progenitor star radius of 700 +/- 200R(circle dot), the size of a red supergiant star. An excess in UV emission two weeks after shock breakout compared with SNe well fitted by model atmosphere-code synthetic spectra with solar metallicity is best explained by suppressed line blanketing due to a lower metallicity progenitor star in SN 2010aq. Continued monitoring of PS1 MDS fields by the GALEX TDS will increase the sample of early UV detections of Type II SNe by an order of magnitude and probe the diversity of SN progenitor star properties.

From observations of filament eruptions recorded with the Extreme-Ultraviolet Imager on STEREO during 2008-2009, it is evident that these dimmings are much more pronounced in 19.5 nm than in the lower-temperature line 17.1 nm, as viewed either on the disk or above the limb. We conclude that most of the cooler coronal plasma is not ejected but remains gravitationally bound when the loops open up. This result is consistent with Doppler measurements by Imada and coworkers, who found that the upflow speeds in a transient coronal hole increased dramatically above a temperature of 1 MK; it is also consistent with the quasistatic behavior of polar plumes, as compared with the hotter interplume regions that are the main source of the fast solar wind. When the open flux reconnects and closes down again, the trapped plasma is initially heated to such high temperatures that it is no longer visible at Fe IX 17.1 nm. Correspondingly, 17.1 nm images show a dark ribbon or "heat wave" propagating away from the polarity inversion line and coinciding with the brightened Fe XV 28.4 nm and Fe XII 19.5 nm post-eruptive loops and their footpoint areas. Such dark ribbons provide a clear example of dimmings that are not caused by a density depletion. The propagation of the "heat wave" is driven by the closing-down, not the opening-up, of the flux and can be observed both off-limb and on-disk.

TI A SURVEY OF STELLAR FAMILIES: MULTIPLICITY OF SOLAR-TYPE STARS SO ASTROPHYSICAL JOURNAL SUPPLEMENT SERIES LA English DT Article DE binaries: general; planetary systems; stars: solar-type; stars: statistics; surveys ID ALL-SKY SURVEY; BROWN DWARF DESERT; EXOPLANET HOST STARS; PROPER-MOTION STARS; SPECTROSCOPIC BINARY ORBITS; ICCD SPECKLE OBSERVATIONS; PHOTOELECTRIC RADIAL-VELOCITIES; LONG-PERIOD COMPANIONS; ADAPTIVE OPTICS SURVEY; RHO-CORONAE-BOREALIS AB We present the results of a comprehensive assessment of companions to solar-type stars. A sample of 454 stars, including the Sun, was selected from the Hipparcos catalog with pi > 40 mas, sigma(pi)/pi < 0.05, 0.5 <= B - V <= 1.0 (similar to F6-K3), and constrained by absolute magnitude and color to exclude evolved stars. These criteria are equivalent to selecting all dwarf and subdwarf stars within 25 pc with V-band flux between 0.1 and 10 times that of the Sun, giving us a physical basis for the term "solar-type." New observational aspects of this work include surveys for (1) very close companions with long-baseline interferometry at the Center for High Angular Resolution Astronomy Array, (2) close companions with speckle interferometry, and (3) wide proper-motion companions identified by blinking multi-epoch archival images. In addition, we include the results from extensive radial-velocity monitoring programs and evaluate companion information from various catalogs covering many different techniques. The results presented here include four new common proper-motion companions discovered by blinking archival images. Additionally, the spectroscopic data searched reveal five new stellar companions. Our synthesis of results from many methods and sources results in a thorough evaluation of stellar and brown dwarf companions to nearby Sun-like stars. The overall observed fractions of single, double, triple, and higher-order systems are 56% +/- 2%, 33% +/- 2%, 8% +/- 1%, and 3% +/- 1%, respectively, counting all confirmed stellar and brown dwarf companions. If all candidate, i.e., unconfirmed, companions identified are found to be real, the percentages would change to 54% +/- 2%, 34% +/- 2%, 9% +/- 2%, and 3% +/- 1%, respectively. Our completeness analysis indicates that only a few undiscovered companions remain in this well-studied sample, implying that the majority (54% +/- 2%) of solar-type stars are single, in contrast to the results of prior multiplicity studies. Our sample is large enough to enable a check of the multiplicity dependence on various physical parameters by analyzing appropriate subsamples. Bluer, more massive stars are seen as more likely to have companions than redder, less massive ones, consistent with the trend seen over the entire spectral range. Systems with larger interaction cross sections, i.e., those with more than two components or long orbital periods, are preferentially younger, suggesting that companions may be stripped over time by dynamical interactions. We confirm the planet-metallicity correlation (i.e., higher metallicity stars are more likely to host planets), but are unable to check it for brown dwarfs due to the paucity of such companions, implying that the brown dwarf desert extends over all separation regimes. We find no correlation between stellar companions and metallicity for B - V < 0.625, but among the redder subset, metal-poor stars ([Fe/H] < -0.3) are more likely to have companions with a 2.4 sigma significance. The orbital-period distribution of companions is unimodal and roughly log normal with a peak and median of about 300 years. The period-eccentricity relation shows the expected circularization for periods below 12 days, caused by tidal forces over the age of the Galaxy, followed by a roughly flat distribution. The mass-ratio distribution shows a preference for like-mass pairs, which occur more frequently in relatively close pairs. The fraction of planet hosts among single, binary, and multiple systems are statistically inditinguishable, suggesting that planets are as likely to form around single stars as they are around components of binary or multiple systems with sufficiently wide separations. This, along with the preference of long orbital periods among stellar systems, increases the space around stars conducive for planet formation, and perhaps life.

TI Investigation of Atmospheric Pressure CVD-Produced Aluminum Coatings for the Protection of Steel from Corrosion SO CHEMICAL VAPOR DEPOSITION LA English DT Article DE Aluminum; APCVD; Corrosion protection; Step coverage; TIBAL ID CHEMICAL-VAPOR-DEPOSITION; CHEMISTRY; CADMIUM AB This study investigates the use of atmospheric pressure (AP)CVD-produced aluminum (Al) coatings for the protection of steel from corrosion. Coatings produced through thermal decomposition of a triisobutylaluminum (TIBAL)-based precursor at 548 and 573 K are shown to exhibit growth rates of 0.5 and 1.1 mu m min(-1), respectively. Glow discharge optical emission spectroscopy (GDOES) reveals that, in the main, the coatings consist of pure Al with oxygen present as a minor constituent. Results of the structural, morphological, electrical, and mechanical characterization reveal that the APCVD Al coatings exhibit a face center cubic (fcc) structure with no preferred orientation, a non-columnar grain structure with grain size ranging from 3 to 10 mu m, and a surface roughness close to 2 mu m. Such coatings are also shown to offer an electrical resistivity of 3.5 mu Omega.cm, a density of 2.60 g cm(-3), and an adhesive strength of 703 kg cm(-2). Cross-sectional examination of coated samples indicate that the APCVD process can yield excellent step coverage and throwing power. Hydrogen embrittlement (HE) tests reveal that Al-coated bars with no post baking experience premature failure due to the presence of incorporated reaction product, hydrogen, in the steel substrate. Samples post-baked at 463 K for 23 h to remove the hydrogen from the substrate are shown to withstand the load for as long as 202 h. Corrosion studies conducted using potentiodynamic polarization measurements, electrochemical impedance spectroscopy, and salt fog tests show that the corrosion resistance of the APCVD Al coatings is comparable to that of pure Al foils, and that such coatings provide acceptable sacrificial protection for steel substrates.

The work consists of experimental testing, utilizing a water filled conical shock tube and computational simulations, utilizing the commercially available LS-DYNA finite element code. Two test series have been performed and simulated: (1) a reduced energy series which allowed for the use of strain gages and (2) a series with increased energy which imparted material damage. The strain gage data and the computational results show a high level of correlation using the Russell error measure. The finite element models are also shown to be able to simulate the onset of material damage by both in-plane and delamination mechanisms. Published by Elsevier Ltd.

The impact of growth temperature, In flux, and ammonia flow on the InN microstructure and epitaxial alignment was evaluated. Increased growth temperature resulted in nanorods with high-aspect ratio and enhanced epitaxial alignment of InN(001)//Al(2)O(3)(001). Faceting exhibited by our growth product confirmed that simple bond-counting does not determine the exhibited planes and phenomena such as dipole-dipole attractions and surface diffusion determined crystal morphology under certain conditions. An increase in growth product with increased In flux indicated our growths are carried out under heavily N-rich conditions with V/III similar to 10(4). These results provide a stronger understanding of the growth mechanisms of this unique semiconductor. C1 [Simpkins, B. S.; Pehrsson, P. E.] USN, Res Lab, Div Chem, Washington, DC 20375 USA.

First, the surface area of Pt3Co/VC catalyst is rigorously characterized by hydrogen adsorption, CO stripping voltammetry and underpotential deposition (upd) of copper adatoms. Then the performance of PEMFC cathodes employing 30 wt.% Pt3Co/VC and 50 wt.% Pt/VC catalysts is compared after exposure to 1 ppm SO2 in air for 3 h at constant cell voltage of 0.6V. In agreement with results reported for the electrode/solution interface, the Pt3Co/VC is more susceptive to SO2 poisoning than Pt/VC at a given platinum loading. Both catalysts can be recovered from adsorbed sulfur species by running successive polarization curves in air or cyclic voltammetry (CV) in inert atmosphere. However, the activity of Pt3Co/VC having similar to 3 times higher sulfur coverage is recovered more easily than Pt/VC. To understand the difference between the two catalysts in terms of activity recovery, platinum-sulfur interaction is probed by thermal programmed desorption at the catalyst/inert gas interface and CV at the electrode/solution interface and in the FC environment.

TI Early changes in vasoreactivity after simulated microgravity are due to an upregulation of the endothelium-dependent nitric oxide/cGMP pathway SO EUROPEAN JOURNAL OF APPLIED PHYSIOLOGY LA English DT Article DE Microgravity; Vascular; Aorta; Hindlimb unweighting; Endothelium ID POSTSPACEFLIGHT ORTHOSTATIC HYPOTENSION; CEREBRAL-ARTERIES; RAT MODEL; SYNTHASE; PHOSPHORYLATION; ACTIVATION; HSP90; CELLS; SPACEFLIGHT; INTOLERANCE AB Emerging evidence suggests that nitric oxide (NO) plays a pivotal role in the mechanism of vascular hyporesponsiveness contributing to microgravity-induced orthostatic intolerance. The cellular and enzymatic source of the NO, however, remains controversial. In addition, the time course of the endothelial-dependent contribution remains unstudied. We tested the hypotheses that the change in vasoresponsiveness seen in acute (3-day) hindlimb unweighted (HLU) animals is due to an endothelium-dependent mechanism and that endothelial-dependent attenuation in vasoreactivity is due to endothelial nitric oxide synthase (NOS-3) dependent activation. Vasoreactivity was investigated in rat aortic rings following acute HLU treatment. Dose responsiveness to norepinepherine (NE) was depressed after 3-day HLU [1,338 +/- A 54 vs. 2,325 +/- A 58 mg at max (NE), HLU vs. C, P < 0.001]. However, removal of the endothelium restored the vascular contractility to that of C. In addition, 1H-oxadiazole quinoxalin-1-one (ODQ), a soluble guanylyl cyclase inhibitor, restored the reduced vasoconstrictor responses to phenylephrine (PE) seen in 3-day HLU rings (1.30 +/- A 0.10 vs. 0.53 +/- A 0.07 g, HLU + ODQ vs. HLU, P = 0.0001). Ca(+) dependent nitric oxide synthase (NOS) activity was increased, as was vascular NO products as a result of HLU. While NOS-3 expression was not increased in HLU rats, phosphorylation of NOS-3 at serine-1177 (an activator of NOS-3) was increased while phosphorylation of serine-495 (an inactivator of NOS-3) was decreased. These findings demonstrate that changes in vasoresponsiveness in the acute HLU model of microgravity are due to an upregulation of the endothelial-dependent NO/cGMP pathway through NOS phosphorylation.

To gain better control of this highly energetic reaction, glycerin was used to coat the reactant particles to form slurry prior to their reaction with water. This process was shown to moderate the rate of gas production, as well as to provide a means for preparing slurry that could be pumped into the reactor vessel. It was also observed that the presence of calcium hydroxide, a by-product of hydrolysis, lowered the solubility of acetylene resulting in a higher initial flow rate due to less acetylene being dissolved in solution. However, the buildup of calcium hydroxide with time inhibited the hydrolysis of both calcium carbide and calcium hydride causing the acetylene and hydrogen flow rates to decrease.

Franklin, Anet TI Cumulative effects of land use, altered fire regime and climate change on persistence of Ceanothus verrucosus, a rare, fire-dependent plant species SO GLOBAL CHANGE BIOLOGY LA English DT Article DE Ceanothus verrucosus; chaparral; climate change; fire; habitat fragmentation; Mediterranean systems; obligate seeding shrub; population model ID SOUTHERN CALIFORNIA; GEOGRAPHIC-DISTRIBUTION; BIODIVERSITY HOTSPOTS; UNITED-STATES; GLOBAL CHANGE; POPULATION; VEGETATION; WILDFIRE; DISPERSAL; SEEDLINGS AB Mediterranean ecosystems are among the highest in species richness and endemism globally and are also among the most sensitive to climate and land-use change. Fire is an important driver of ecosystem processes in these systems; however, fire regimes have been substantially changed by human activities. Climate change is predicted to further alter fire regimes and species distributions, leading to habitat loss and threatening biodiversity. It is currently unknown what the population-level effects of these landscape-level changes will be. We linked a spatially explicit stochastic population model to dynamic bioclimate envelopes to investigate the effects of climate change, habitat loss and fragm entation and altered fire regime on population abundances of a long-lived obligate seeding shrub, Ceanothus verrucosus, a rare endemic species of southern California. We tested a range of fire return intervals under the present and two future climate scenarios. We also assessed the impact of potential anthropogenic land-use change by excluding land identified as developable by local governments. We found that the 35-50 year fire return interval resulted in the highest population abundances. Expected minimum population abundance (EMA) declined gradually as fire return interval increased, but declined dramatically for shorter fire intervals. Simulated future development resulted in a 33% decline in EMA, but relatively stable population trajectories over the time frame modeled. Relative changes in EMA for alternative fire intervals were similar for all climate and habitat loss scenarios, except under the more severe climate scenario which resulted in a change in the relative ranking of the fire scenarios. Our results show climate change to be the most serious threat facing obligate seeding shrubs embedded in urban landscapes, resulting in population decline and increased local extirpation, and that likely interactions with other threats increase risks to these species. Taking account of parameter uncertainty did not alter our conclusions. C1 [Lawson, Dawn M.; Franklin, Anet] San Diego State Univ, Dept Biol, San Diego, CA 92182 USA.

We assessed platelet carbonic anhydrase activity and catecholamine-induced platelet aggregation in the presence of a thiazide and a "thiazide-like" inhibitor of the sodium-chloride cotransporter. Individual variation in platelet carbonic anhydrase activity correlated with contrasting sensitivity to epinephrine-mediated platelet aggregation. Both chlorthalidone, which potently inhibits platelet carbonic anhydrase, and bendroflumethiazide, which has much less effect on this enzyme, increased the amount of epinephrine needed to induce platelet aggregation when compared with the absence of a diuretic. However, chlorthalidone was significantly more effective than bendroflumethiazide in reducing epinephrine-mediated platelet aggregation. Chlorthalidone also induced marked changes in the number of gene transcripts for two proteins that mediate angiogenesis and vascular permeability, vascular endothelial growth factor C and transforming growth factor-beta 3; chlorthalidone and bendroflumethiazide had contrasting effects on the expression of vascular endothelial growth factor C. Chlorthalidone and bendroflumethiazide reduced vascular permeability to albumin, but only chlorthalidone increased angiogenesis. Thiazides and thiazide-like diuretics can comparably reduce blood pressure, but the drugs in this class are not all alike. It can be suggested from our findings that thiazide and thiazide-like diuretics vary in their pleiotropic effects on platelets and in the vasculature, and these differences could explain the contrasting ability of these drugs to reduce cardiovascular morbidity despite comparable reduction in blood pressure.

In this case, the improvement in performance is determined by the receiver's ability to resolve signal-photon arrival times. We use fast clock recovery and commercially available single-photon detectors with timing resolution enhanced by additional electronic circuitry to implement temporal gating down to 50 ps in a free-space QKD system. The single-photon channel operates at 850 nm, and the improved timing resolution enables transmission rates of 1.25 GHz. We observe daytime quantum bit error rates of 0.04, which is less than one-third of the ungated error rate. We present the design and performance of the system and demonstrate its benefit to free-space QKD.

TI Analysis of a Wavelength-Scaled Array (WSA) Architecture SO IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION LA English DT Article DE Antenna arrays; domain decomposition; phased arrays; ultrawideband arrays; wavelength-scaled arrays ID FINITE ANTENNA-ARRAYS; DESIGN; ELEMENTS AB Wavelength-scaled array architectures use scaled elements to achieve ultrawideband performance with significantly fewer overall radiators than traditional ultrawideband arrays based on a single element type. Compared to a conventional ultrawideband array with 8:1 bandwidth, a wavelength-scaled array that uses elements of three different sizes creates an aperture with fewer than 16% of the original element count, i.e., 6.4-times fewer elements, and by extension a comparable reduction in electronics required to feed the array. In this paper, a study of an asymmetric wavelength-scaled array architecture is presented for finite arrays of offset-centered dual-polarized flared-notch radiators. The unique element transitions within the finite array structure are modeled via a non-matching grid Domain Decomposition-Finite Element Method that allows for rigorous impedance and radiation pattern prediction of full-sized wavelength-scaled arrays. This design study shows that the wavelength-scaled array has comparable performance to traditional ultrawideband arrays in terms of VSWR, radiation patterns, array mismatch efficiency, and cross-polarization levels.

The AR surface, we call an inverse motheye, was formed by machining a multi-layer grating of subwavelength circular holes into a non-absorptive dielectric. This created low reflected energies (< -30 dB) over reasonably large bandwidths and incidence angles. An optimization algorithm, based on a direct pattern search, integrated with a rigorous electromagnetic model was used to design the grating geometries. Experimental results are provided at Ka-band demonstrating the validity of the method. C1 [Mirotznik, Mark S.; Good, Brandon L.] Univ Delaware, Newark, DE 19716 USA.

The first revolution was with integrated circuits which gave us the microprocessor, PCs, cell phones, and MP3 players. The second electronic revolution started with power electronics, which give us motor controllers, switching power supplies, hybrid cars, and electric ships. Just as the first electronic revolution changed our concepts of information, the second electronic revolution is redefining control. This paper discusses these changes and the opportunities enabled by new technologies and levels of control. Most notably, this paper provides a logical argument for future controller abilities to control any system to near perfection-accurately, precisely, reliably, and safely. This paper also proposes the use of building block concepts with modeling and simulation to create new tools and methods for designing and building power systems.

These high nonlinearities also allow efficient supercontinuum generation, which is useful for broadband sources in the near and mid-IR. These materials can also be poled to induce an effective chi((2)), opening up the potential of waveguide parametric amplifiers and sources. The Brillouin gain coefficients are relatively large and enable the demonstration of slow light in small core fibers.

TI From nation-states in conflict to conflict in nation-states: The United States of America and nation building from South Vietnam to Afghanistan SO INTERNATIONAL POLITICS LA English DT Article DE nation building; nation-state; security; development; geopolitics; failed state ID FAILED STATES AB This article engages with the latest (post-Cold War) debate about the theory and practice of nation building (state building). This is linked to a discussion of the shift in US foreign policy towards Afghanistan relative to Iraq between late 2008 and late 2009. Afghanistan is currently a major focus of nation building efforts and counter-insurgency programs led by the United States of America. Meanwhile, the discussion here ranges from South Vietnam to Colombia, Iraq and Afghanistan, and explores some of the ghosts that now haunt the US presence in Afghanistan 9 years on from the start Operation Enduring Freedom at the end of 2001. We argue that the possibility of successful nation building in Afghanistan is both far-fetched and far-off. In fact, what is required is the reorientation and reduction (even termination) of Washington and its allies' direct commitment to Kabul. Washington and its allies should focus on a grand strategy for the Middle East and Asia that attaches far less importance to Afghanistan. This should occur in the context of understanding the history of the emergence, universalization and contemporary crisis of the nation-state system. Nowhere are the limits of the nation-state system and the failure of nation building more apparent today than in Afghanistan. In this context a whole new approach to questions of war, peace and progress is in order. The comprehensive elaboration of a new security-development framework is beyond the scope of this article, but we conclude by elaborating some of the main elements of a new framework: this will include a point of departure for research and policy to move beyond the current crisis of the nation-state system and nation building.

TI Stochastic Modeling of Incident Gust Effects on Aerodynamic Lift SO JOURNAL OF AIRCRAFT LA English DT Article ID UNCERTAINTY QUANTIFICATION; POLYNOMIAL CHAOS; FLOW SIMULATIONS; TURBULENCE AB The intrusive formulation of polynomial chaos expansion is implemented to determine uncertainty in aerodynamic loads on a rigid airfoil due to imprecise parameters that characterize an incoming gust. The results yield the sensitivity of the lift coefficient to variations in intensities and integral length scales of the gust fluctuations. The results show that lift coefficient fluctuations about the mean of each time step are affected primarily by the intensity of the fluctuations of the vertical velocity component, which should be expected. Next in order of importance is the integral length scale of the vertical velocity component. This implementation of the intrusive polynomial chaos expansion provides guidance for future efforts to quantify uncertain gust loads on micro air vehicles with higher fidelity models.

The target response of covered TNT impacted by single fragments is predicted through numerically determined shock-to-detonation thresholds as well as empirical penetration equations. Included in the methodology is a comprehensive, deterministic endgame model that consists of an intercept model, a static and dynamic fragment model, and a hit model generating the number of effective hits for arbitrary intercept situations. Experimental data supporting the assumptions of the models are reported. The model is also useful in establishing interceptor requirements.

No discernible change was seen in the Z(1/2) and EH(6/7) trap concentrations for films grown on both orientations with electron concentrations in the range of 1 x 10(14) to 1 x 10(16) cm(-3), suggesting that the Z(1/2) and EH(6/7) traps are not associated with isolated carbon vacancies. The defect concentrations did not correlate with the measured carrier lifetimes, which is consistent with a carrier lifetime controlled by other recombination centers. Observed decreases in lifetime were related to increases in doping levels, with similar trends seen for both orientations. Carrier lifetimes in 8 degrees material were slightly longer than in 4 degrees films for similar doping concentrations, most likely being associated with surface recombination and/or extended defects.

TI Arthroscopic Repair of Circumferential Lesions of the Glenoid Labrum Surgical Technique SO JOURNAL OF BONE AND JOINT SURGERY-AMERICAN VOLUME LA English DT Article AB BACKGROUND: Symptomatic pan-labral or circumferential (360) tears of the glenohumeral labrum are an uncommon injury. The purpose of the present study was to report the results of surgical treatment of circumferential lesions of the glenoid labrum with use of validated outcome instruments. METHODS: From July 2003 to May 2006, forty-one shoulders in thirty-nine patients (thirty-four men and five women) with a mean age of 25.1 years were prospectively enrolled in a multicenter study and were managed for a circumferential (360) lesion of the glenoid labrum. All patients had a primary diagnosis of pain and recurrent shoulder instability, and all underwent arthroscopic repair of the circumferential labral tear with a mean of 7.1 suture anchors. The outcomes for thirty-nine of the forty-one shoulders were assessed after a mean duration of follow-up of 31.8 months on the basis of the rating of pain and instability on a scale of 0 to 10, a physical examination, and three outcome instruments (the Single Assessment Numeric Evaluation score, the modified American Shoulder and Elbow Surgeons score, and the Short Form-12 score). RESULTS: Significant improvement was noted in terms of the mean pain score (from 4.3 to 1.1), the mean instability score (from 7.3 to 0.2), the mean modified American Shoulder and Elbow Surgeons score (from 55.5 to 89.6), the mean Short Form-12 score (from 75.7 to 90.0), and the mean Single Assessment Numeric Evaluation score (from 36.7 to 88.5). Six shoulders required revision surgery because of recurrent instability (two), recalcitrant biceps tendinitis (two), or postoperative tightness (two). All patients returned to their preinjury activity level. CONCLUSIONS: Pan-labral or circumferential lesions are an uncommon yet extensive injury of the glenohumeral joint that may result in recurrent instability and pain. The present study demonstrates that arthroscopic capsulolabral repair with suture anchor fixation can restore the stability of the glenohumeral joint and can provide a reliable improvement in subjective and objective outcome measures.

TI Genotypic and Phenotypic Characterization of Enterotoxigenic Escherichia coli Strains Isolated from Peruvian Children SO JOURNAL OF CLINICAL MICROBIOLOGY LA English DT Article ID GM1-ENZYME-LINKED IMMUNOSORBENT-ASSAY; COLONIZATION FACTORS; MONOCLONAL-ANTIBODIES; DEVELOPING-COUNTRIES; PROSPECTIVE COHORT; DIARRHEA; TOXIN; DISEASE; ETEC; INFECTIONS AB Enterotoxigenic Escherichia coli (ETEC) is a major cause of childhood diarrhea. The present study sought to determine the prevalence and distribution of toxin types, colonization factors (CFs), and antimicrobial susceptibility of ETEC strains isolated from Peruvian children. We analyzed ETEC strains isolated from Peruvian children between 2 and 24 months of age in a passive surveillance study. Five E. coli colonies per patient were studied by multiplex real-time PCR to identify ETEC virulence factors. ETEC-associated toxins were confirmed using a GM1-based enzyme-linked immunosorbent assay. Confirmed strains were tested for CFs by dot blot assay using 21 monoclonal antibodies. We analyzed 1,129 samples from children with diarrhea and 744 control children and found ETEC in 5.3% and 4.3%, respectively. ETEC was more frequently isolated from children > 12 months of age than from children < 12 months of age (P < 0.001). Fifty-two percent of ETEC isolates from children with diarrhea and 72% of isolates from controls were heat-labile enterotoxin (LT) positive and heat-stable enterotoxin (ST) negative; 25% and 19%, respectively, were LT negative and ST positive; and 23% and 9%, respectively, were LT positive and ST positive. CFs were identified in 64% of diarrheal samples and 37% of control samples (P < 0.05). The most common CFs were CS6 (14% and 7%, respectively), CS12 (12% and 4%, respectively), and CS1 (9% and 4%, respectively). ST-producing ETEC strains caused more severe diarrhea than non-ST-producing ETEC strains. The strains were most frequently resistant to ampicillin (71%) and co-trimoxazole (61%). ETEC was thus found to be more prevalent in older infants. LT was the most common toxin type; 64% of strains had an identified CF. These data are relevant in estimating the burden of disease due to ETEC and the potential coverage of children in Peru by investigational vaccines. C1 [Ochoa, T.

The acoustics objective was to quantify the temporal and spatial variability in acoustic propagation characteristics on the continental shelf in the presence of locally-generated and trans-basin nonlinear internal waves (NLIW). Broadband (400 Hz center frequency) m-sequence signals transmitted nearly continuously by a source moored near the seabed were received by vertical line arrays at 3 and 6 km range. The acoustic transect was oriented approximately parallel to the wave fronts of the shoaling trans-basin NLIW's which had crossed the deep basin from their origin in the Luzon Strait. The acoustic propagation variability due to strong vertical and horizontal refraction induced by the very large NLIW's creates an extremely complex acoustic field as a function of time and space. Experimental data and numerical acoustic propagation modeling results are presented to (1) examine and estimate the contribution of internal wave induced horizontal refraction to the received acoustic field; and (2) to quantify the range of propagation angles relative to the internal wave fronts within which strong horizontal refraction occurs and 3D propagation models are required to accurately predict the range-and depth-dependent acoustic propagation.

Benjamin TI THREE-DIMENSIONAL ACOUSTIC SIMULATION OF AN ACOUSTIC REFRACTION BY A NONLINEAR INTERNAL WAVE IN A WEDGE BATHYMETRY SO JOURNAL OF COMPUTATIONAL ACOUSTICS LA English DT Article DE Nonlinear internal wave (NIW); WA-FOR3D; 3D effect; horizontal refraction ID SOUTH CHINA SEA; CROSS-RANGE COHERENCE; SHALLOW-WATER; SOUND INTENSITY; PROPAGATION; SOLITONS; FIELD; PACKETS; MODEL; TIME AB Nonlinear internal wave (NIW) results in three dimensional acoustic effect such as ducting and whispering gallery effects in acoustic propagation. Acoustic energy restricted within internal wave crests (crest-crest) on the shelf constitutes the ducting effect, and energy confined along the crest when the source is located upslope from the NIW crest is known as the whispering gallery effect. Numerical experiments are presented in this paper for the study of 3D acoustic effects caused by both internal wave and wedge-bathymetry. 3D effects are predicted by Wide-Angle- FOR3D and the modal contents are calculated by MOS3DPEF. Following are the case studies detailing differences between 2D and 3D calculation, and the joint effect of propagating internal waves with upslope-bathymetry. Modeled time series of transmission Loss reveal that internal wave induces the oceanic waveguide and concentrate acoustic energy along the wave front. By modeling larger calculation ranges (20 km) and deeper deploying sources, the changing of the growth and decline of acoustic energy and lower acoustic mode amplitude by range, along the front of internal wave can be observed in this paper.

Our samples are spontaneously nucleated thin platelets of approximate dimensions of 2 x 2 x 0.025 mm(3), or samples grown on both polycrystalline and single crystal HVPE large-area (similar to 3 x 8 x 0.5 mm(3)) seeds. Electron paramagnetic resonance spectra consists of a single Lorentzian line with axial symmetry about the c-axis, with approximate g-values, g(parallel to) = 1.951 and g(perpendicular to) = 1.948 and a peak-to-peak linewidth of similar to 4.0 G. This resonance has been previously assigned to shallow impurity donors/conduction electrons in GaN and attributed to Si- and/or O impurities. Room temperature photoluminescence and photoluminescence imaging data from both Ga- and N-faces show different dominant emission bands, suggesting different incorporation of impurities and/or native defects. Raman scattering and X-ray diffraction show moderate to good crystalline quality. (C) 2010 Elsevier B.V. All rights reserved. C1 [Garces, N. Y.; Feigelson, B. N.; Freitas, J.

To this aim, a metal organic chemical vapor deposition process was developed to create a (14 mu m) thick stress-free homoepitaxial GaN film. Low temperature photoluminescence measurements are consistent with low donor background and low concentration of deep compensating centers. Capacitance-voltage measurements performed at 30 degrees C verified a low level of about 2 x 10(15) cm(-3) of n-type free carriers (unintentional doping), which enabled a breakdown voltage of about 500 V. A secondary ion mass spectrometry depth profile confirms the low concentration of background impurities and X-ray diffraction extracted a low dislocation density in the film. These results indicate that thick GaN films can be deposited with free carrier concentrations sufficiently low to enable high voltage rectifiers for power switching applications.

A set of linear time-invariant equivalent models of the faulty hydraulic actuator is first established, in the frequency domain, by Fourier transformation of acceptable actuator input-output responses. Then, a robust position control law is synthesized by quantitative feedback theory to meet the prescribed design tolerances on closed-loop stability and reference tracking. The designed fault tolerant controller uses only actuator position as feedback, yet it can accommodate nonlinearities in the hydraulic functions, maintain robustness against typical parametric uncertainties, and maintain the closed-loop performance despite a leakage fault that can bypass up to 40% of the rated servovalve flow across the actuator piston. To demonstrate the utility of the fault tolerant control approach in a realistic application, the experimental fault tolerant hydraulic system is operated as a flight surface actuator in the hardware-in-the-loop simulation of a high-performance jet aircraft.

In addition to the restrictions made in 2003 by the Accreditation Council for Graduate Medical Education, the potential effects of the 2008 Institute of Medicine (IOM) report on resident duty hours were postulated. Discussion: The elements highlighted include patient safety, resident wellness, and the resident training experience. Many of the changes and recommendations did not affect EM as significantly as other specialties. Current training standards in EM have already emphasized patient safety by requiring continuous onsite supervision of residents. Resident fatigue has been addressed with restrictions of shift lengths and limitation of consecutive days worked. Conclusion: One recommendation from the IOM was a required 5-h rest period for residents on call. Emergency department (ED) patient safety becomes an important concern with the decrease in the availability and in the patient load of a resident consultant that may result from this recommendation. Of greater concern is the already observed slower throughput time for admitted patients waiting for resident care, which will increase ED crowding and decrease patient safety in academic institutions. A balance between being overly prescriptive with duty hour restrictions and trying to improve resident wellness was recommended. Discussion is included regarding the appropriate length of EM training programs if clinical experiences were limited by new duty hour regulations. Finally, this report presents a review of the financing issues associated with any changes. (C) 2010 Elsevier Inc. C1 [Wagner, Mary Jo] Michigan State Univ, E Lansing, MI 48824 USA.

Heyes, Andrew Pullen, Keith TI Design Overview of a Three Kilowatt Recuperated Ceramic Turboshaft Engine SO JOURNAL OF ENGINEERING FOR GAS TURBINES AND POWER-TRANSACTIONS OF THE ASME LA English DT Article ID WATER-VAPOR; MICROTURBINES; OXIDATION AB A three kilowatt turboshaft engine with a ceramic recuperator and turbine has been designed for small unmanned air vehicle (UAV) propulsion and portable power generation. Compared with internal combustion (IC) engines, gas turbines offer superior reliability, engine life, noise and vibration characteristics, and compatibility with military fuels. However, the efficiency of miniature gas turbines must be improved substantially, without severely compromising weight and cost, if they are to compete effectively with small IC engines for long-endurance UAV propulsion. This paper presents a design overview and supporting analytical results for an engine that could meet this goal. The system architecture was chosen to accommodate the limitations of mature, cost-effective ceramic materials: silicon nitride for the turbine rotors and toughened mullite for the heat exchanger and turbine stators. An engine with a cycle pressure ratio below 2:1, a multistage turbine, and a highly effective recuperator is shown to have numerous advantages in this context. A key benefit is a very low water vapor-induced surface recession rate for silicon nitride, due to an extremely low partial pressure of water in the combustion products. Others include reduced sensitivity to internal flaws, creep, and foreign object damage; an output shaft speed low enough for grease-lubricated bearings; and the potential viability of a novel premixed heat-recirculating combustor.

Gregory TI Measuring Search Efficiency in Complex Visual Search Tasks: Global and Local Clutter SO JOURNAL OF EXPERIMENTAL PSYCHOLOGY-APPLIED LA English DT Article DE visual search; clutter; attention ID CORTICAL MAGNIFICATION; FEATURE-INTEGRATION; ATTENTION; PRECEDENCE; TARGET; PARALLEL; FEATURES; OBJECTS; MEMORY; DEPEND AB Set size and crowding affect search efficiency by limiting attention for recognition and attention against competition; however, these factors can be difficult to quantify in complex search tasks. The current experiments use a quantitative measure of the amount and variability of visual information (i.e., clutter) in highly complex stimuli (i.e., digital aeronautical charts) to examine limits of attention in visual search. Undergraduates at a large southern university searched for a target among 4, 8, or 16 distractors in charts with high, medium, or low global clutter. The target was in a high or low local-clutter region of the chart. In Experiment 1, reaction time increased as global clutter increased, particularly when the target was in a high local-clutter region. However, there was no effect of distractor set size, supporting the notion that global clutter is a better measure of attention against competition in complex visual search tasks. As a control, Experiment 2 demonstrated that increasing the number of distractors leads to a typical set size effect when there is no additional clutter (i.e., no chart). In Experiment 3, the effects of global and local clutter were minimized when the target was highly salient. When the target was nonsalient, more fixations were observed in high global clutter charts, indicating that the number of elements competing with the target for attention was also high. The results suggest design techniques that could improve pilots' search performance in aeronautical charts. C1 [Beck, Melissa R.] Louisiana State Univ, Dept Psychol, Baton Rouge, LA 70808 USA.

TI Sodium tungstate (Na2WO4) exposure increases apoptosis in human peripheral blood lymphocytes SO JOURNAL OF IMMUNOTOXICOLOGY LA English DT Article DE Apoptosis; cytokine; lymphocyte; sodium tungstate ID SYSTEMIC INFLAMMATION; ANTIDIABETIC AGENT; XANTHINE-OXIDASE; HISTONE H1.2; CELLS; RATS; INHIBITION; PHOSPHORYLATION; PROLIFERATION; TRANSITION AB The potential for adverse health effects of using tungsten and its alloys in military munitions are an important concern to both civilians and the US military. The toxicological implications of exposure to tungsten, its alloys, and the soluble tungstate (Na2WO4) are currently under investigation. To examine tungstate toxicity, a series of experiments to determine its in vitro effects on cells of the immune system were performed. We identified alterations in isolated human peripheral blood lymphocytes (PBL) treated in vitro with sodium tungstate (0.01, 0.1, 1.0, and 10 mM). Analyses of apoptosis with annexin V and propidium iodide revealed a dose-and time-dependent increase in the quantity of cells in early apoptosis after tungstate exposure. Reductions in the number of cells entering into the cell cycle were also noted. Exposure of PBL to tungstate (1 mM) and Concanavalin A (ConA) for 72 h reduced the number of cells in S and G(2)/M phases of the cell cycle. There were alterations in the numbers of cells in G(0)/G(1), S, and G(2)/M phases of the cell cycle in long-term THP-1 (acute leukemic monocytes) cultures treated with tungstate (0.01, 0.1, 1.0, and 10 mM). Gel electrophoresis, silver staining, and LC-MS/MS showed the cytoplasmic presence of histone H1b and H1d after 72 h of tungstate exposure. The addition of tungstate to cultures resulted in significant reductions in the quantity of interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-alpha), and IL-6 produced by stimulated [CD3/CD28, ConA, or lipopolysaccharide (LPS)] and tungstate-treated lymphocytes. Taken together, these data indicate that tungstate increases apoptosis of PBL, alters cell cycle progression, reduces cytokine production, and therefore warrants further investigation.

TI Detection of gyrA mutation among clinical isolates of Campylobacter jejuni isolated in Egypt by MAMA PCR SO JOURNAL OF INFECTION IN DEVELOPING COUNTRIES LA English DT Article DE fluoroquinolone resistance; mismatch sequence detection; Africa AB Introduction: Campylobacter spp are the major cause of enteritis in humans and more than 90% of reported infections are caused by Campylobacter jejuni. Fluoroquinolones such as ciprofloxacin are the antibiotics of choice for treatment. An increase in the frequency of ciprofloxacin-resistant Campylobacter has been reported globally due to a single base mutation (C-257 to T) in codon 86 of the quinolone resistance determining region (QRDR) of the gyrA gene altering the amino acid sequence from threonine at position 86 to isoleucine (Thr-86 to Ile). Methodology: Campylobacter spp (n = 118) were selected from a collection of Egyptian isolates spanning 1998 to 2005. The presence of C. jejuni gyrA gene was confirmed in each isolate by a PCR assay amplifying 368bp portion of the gyrA gene. C to T alteration was detected by the mismatch amplification mutation assay MAMA PCR. The MIC of nalidixic acid (NA) and ciprofloxacin (CIP) was determined by E-test. Results: C. jejuni gyrA gene was detected in 100 of the Campylobacter spp studied; the other 18 isolates were found to be Campylobacter coli by lpxA PCR. The mutation was detected in 89 C. jejuni resistant isolates with MIC values (NA; 8 - >256 mu g/ml) and (CIP; 4 - >32 mu g/ml). The other 11 sensitive C. jejuni isolates with MIC values (NA; 0.38 - 3 mu g/ml) and (CIP; 0.03 - 0.125 mu g/ml) were not amplified by the MAMA primers. There was 100% congruence with MAMA PCR, MIC results and gyrA gene sequence analysis. Conclusions: In Egypt the main mechanism for resistance to fluoroquinolones is an alteration in the gyrA QRDR. MAMA PCR provides an economical and rapid means for screening fluoroquinolone resistance.

TI Strain path and microstructure evolution during severe deformation processing of an as-cast hypoeutectic Al-Si alloy SO JOURNAL OF MATERIALS SCIENCE LA English DT Article; Proceedings Paper CT 6th International Symposium on Ultrafine Grained Materials CY FEB 14-18, 2010 CL Seattle, WA SP Minerals, Metals & Mat Soc ID SEVERE PLASTIC-DEFORMATION; HIGH-PRESSURE TORSION; GRAIN-REFINEMENT AB Microstructure evolution in an as-cast Na modified Al-7%Si (wt. pct.) alloy was examined during redundant and monotonic straining by repetitive equi-channel angular pressing (ECAP) under ambient temperature conditions, and during friction stir processing (FSP). Redundant straining during repetitive ECAP was accomplished by processing following route B(C) while monotonic straining employed route A. Single- and multi-pass FSP was conducted on this same as-cast material using an FSP tool having a threaded pin. The as-cast microstructure comprises equiaxed primary alpha dendrite cells embedded in the Al-Si eutectic constituent. The evolution of this microstructure during repetitive ECAP can be described by idealized models of this process. The primary and eutectic constituents can still be discerned and the Si particle distribution is not homogenized even during ambient temperature processing involving von Mises strains > 9.0. In contrast, the primary and eutectic constituents cannot be distinguished in the stir zone after even a single FSP pass. Strain estimates based on the shape change of the primary alpha constituent indicate that the Si particle distribution has become homogeneous at local von Mises strains of 2.5-3.0 during the FSP thermomechanical cycle. Mechanical property data are consistent with strain path during SPD processing by repetitive ECAP and FSP. C1 [Su, J. Q.; Menon, S. K.; McNelley, T.

TI Probabilistic (Bayesian) Modeling of Gene Expression in Transplant Glomerulopathy SO JOURNAL OF MOLECULAR DIAGNOSTICS LA English DT Article ID CHRONIC ALLOGRAFT NEPHROPATHY; GROWTH-FACTOR-BETA; RENAL-TRANSPLANTATION; FUTURE-DIRECTIONS; ACUTE REJECTION; T-CELLS; RECIPIENTS; BIOPSIES; INJURY; C4D AB Transplant glomerulopathy (TG) is associated with rapid decline in glomerular filtration rate and poor outcome. We used low-density arrays with a novel probabilistic analysis to characterize relationships between gene transcripts and the development of TG in allograft recipients. Retrospective review identified TG in 10.8% of 963 core biopsies from 166 patients; patients with stable function were studied for comparison. The biopsies were analyzed for expression of 87 genes related to immune function and fibrosis by using real-time PCR, and a Bayesian model was generated and validated to predict histopathology based on gene expression. A total of 57 individual genes were increased in TG compared with stable function biopsies (P < 0.05). The Bayesian analysis identified critical relationships between ICAM-1, IL-10, CCL3, CD86, VCAM-1, MMP-9, MMP-7, and LAMC2 and allograft pathology. Moreover, Bayesian models predicted TG when derived from either immune function (area under the curve [95% confidence interval] of 0.875 [0.675 to 0.999], P = 0.004) or fibrosis (area under the curve [95% confidence interval] of 0.859 [0.754 to 0.963], P < 0.001) gene networks. Critical pathways in the Bayesian models were also analyzed by using the Fisher exact test and had P values <0.005. This study demonstrates that evaluating quantitative gene expression profiles with Bayesian modeling can identify significant transcriptional associations that have the potential to support the diagnostic capability of allograft histology. This integrated approach has broad implications in the field of transplant diagnostics.

Part I: Definition, Calibration, and Validation SO JOURNAL OF PHYSICAL OCEANOGRAPHY LA English DT Article ID ATMOSPHERIC BOUNDARY-LAYER; WIND-GENERATED WAVES; QUASI-LINEAR THEORY; GRAVITY-WAVES; BREAKING WAVES; ENERGY-DISSIPATION; EQUILIBRIUM RANGE; SURFACE-WAVES; MODEL; SPECTRUM AB New parameterizations for the spectral dissipation of wind-generated waves are proposed. The rates of dissipation have no predetermined spectral shapes and are functions of the wave spectrum and wind speed and direction, in a way consistent with observations of wave breaking and swell dissipation properties. Namely, the swell dissipation is nonlinear and proportional to the swell steepness, and dissipation due to wave breaking is nonzero only when a nondimensional spectrum exceeds the threshold at which waves are observed to start breaking. An additional source of short-wave dissipation is introduced to represent the dissipation of short waves due to longer breaking waves. A reduction of the wind-wave generation of short waves is meant to account for the momentum flux absorbed by longer waves. These parameterizations are combined and calibrated with the discrete interaction approximation for the nonlinear interactions. Parameters are adjusted to reproduce observed shapes of directional wave spectra, and the variability of spectral moments with wind speed and wave height. The wave energy balance is verified in a wide range of conditions and scales, from the global ocean to coastal settings. Wave height, peak and mean periods, and spectral data are validated using in situ and remote sensing data. Some systematic defects are still present, but, overall, the parameterizations probably yield the most accurate estimates of wave parameters to date. Perspectives for further improvement are also given. C1 [Ardhuin, Fabrice; Filipot, Jean-Francois; Magne, Rudy; Queffeulou, Pierre] Serv Hydrog & Oceanog Marine, Brest, France.

TI A Modeling Study of Circulation and Eddies in the Persian Gulf SO JOURNAL OF PHYSICAL OCEANOGRAPHY LA English DT Article ID ARABIAN GULF; RESIDUAL CURRENTS; COMPUTATION; DRIVEN; HORMUZ; STRAIT; FLOW AB The circulation and mesoscale eddies in the Persian Gulf are investigated using results from a high-resolution (similar to 1 km) Hybrid Coordinate Ocean Model (HYCOM). The circulation in the Persian Gulf is composed of two spatial scales: basin scale and mesoscale. The progression of a cyclonic circulation cell dominates the basin-scale circulation in the eastern half of the gulf (52 degrees-55 degrees E) during March-July. This is primarily the consequence of density-driven outflow-inflow through the Strait of Hormuz and strong stratification. A northwestward-flowing Iranian Coastal Current (ICC; 30-40 cm s(-1)) between the Strait of Hormuz and north of Qatar (similar to 52 degrees E) forms the northern flank of the cell. Between July and August the ICC becomes unstable because of the baroclinic instability mechanism by releasing the potential energy stored in the cross-shelf density gradient. As a result, the meanders in the ICC evolve into a series of mesoscale eddies, which is denoted as the Iranian coastal eddies (ICE). The ICE have a diameter of about 115-130 km and extend vertically over most of the water column. Three cyclonic eddies produced by the model during August-September 2005 compared quite well with the Moderate Resolution Imaging Spectroradiometer (MODIS) SST and chlorophyll-a observations. The remnants of ICE are seen until November, after which they dissipate as the winter cooling causes the thermocline to collapse.

TI Effects of duration of injection drug use and age at first injection on HCV among IDU in Kabul, Afghanistan(dagger) SO JOURNAL OF PUBLIC HEALTH LA English DT Article DE Afghanistan; age; duration; first injection; HCV; IDU; risk ID HEPATITIS-C VIRUS; RISK-FACTORS; INFECTION; PREVALENCE; HIV; PROGRAMS; SEROCONVERSION; TRANSMISSION; INITIATION; EQUIPMENT AB Hepatitis C virus (HCV) prevalence is high among injection drug users (IDUs) in Afghanistan. Duration of injection and young age at first injection are common risk factors for HCV in IDU populations. The association of HCV with these time factors was analyzed. Socio-demographic and drug use behavior information were collected. Participants had rapid testing for HCV with recombinant immunoblot assay confirmation. Modeling of non-linear associations was performed using fractional polynomial logistic regression. Among 459 male IDUs, age at first injection had a constant HCV risk (odds ratio (OR): 1.01 per year; 95% confidence interval (CI): 0.98-1.03), while each additional year of injection drug use had a significantly increased risk (OR: 4.72 per year, 95% CI: 2.92-7.66). HCV risk increased significantly with each additional year of injecting drug use by groups of injectors: young (< 22 years, OR: 1.97; 95% CI: 1.27-3.07), middle (23-28 years, OR: 1.76; 95% CI: 1.28-2.43) and older (>= 29 years, OR: 7.56; 95% CI: 3.15-18.14). The probability of HCV infection increased markedly by duration of injection drug use and varied according to age at first injection. Drug counseling and educational efforts should be directed to older drug users who have not yet initiated injecting and to young IDUs to avert infection and reduce risky drug use behaviors.

TI An Experimental Method to Satisfy Dynamic Similarity Requirements for Model Submarine Maneuvers SO JOURNAL OF SHIP RESEARCH LA English DT Article DE hydrodynamics (hull form); submersibles; manuevering AB Dimensional analysis and dynamic similarity requirements show that Reynolds, Froude, and Strouhal scales are important parameters to be satisfied for free-running submarine model (FRM) maneuvering experiments so that they correctly represent full-scale behavior. The requirement that all three scales be satisfied simultaneously presents conflicting demands on the relationship between the velocity U and the characteristic length L of the model. The inability to meet these demands presents technical challenges to properly satisfy dynamic similarity for the FRM. Instead, we take a first-principles approach by considering the forces and moments acting on the vehicle and seek solutions that dynamically produce the same scaled forces and moments on the model as exist on the full-scale vehicle. Thus, this paper presents an extended dynamic similarity theory, introducing scaling formulas that have been derived from similarity solutions. These are applied to an unsteady turning maneuver of the FRM to suggest an improved experimental program. The improved approach will then dynamically satisfy the aforementioned three scaling parameters. C1 [Shen, Young T.; Hess, David E.] USN, Ctr Surface Warfare, Bethesda, MD USA.

TI Vibration of elliptic cylindrical shells: Higher order shell theory SO JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA LA English DT Article ID CIRCUMFERENTIALLY VARYING THICKNESS; PROPAGATION; WAVES AB The equations for the free vibration of an elliptic cylindrical shell of constant thickness were derived using a Ritz approach. A higher order shell theory is employed that includes the effects of shear deformation, rotary inertia, and symmetric and antisymmetric thickness stretch deformations. The frequency-wavenumber spectrum has seven branches: flexural, extensional, torsional, two thickness shear, and two thickness stretch. The resulting seven coupled algebraic equations are symmetric and positive definite. The shell has a constant thickness, h, finite length, L, and is "simply supported" at its ends, (z=0, L), where z is the axial coordinate. The elliptic cross-section is defined by the shape parameter, a, and the half-length of the major axis, l. The modal solutions are expanded in a doubly infinite series of comparison functions in terms of circular functions in the angular and axial coordinates. Numerical results for the natural frequencies were obtained for two values of h/l and L/l, and various shape parameters, including the limiting case of a simply supported cylindrical shell (a approximate to 100).

TI The acoustic field on the forehead of echolocating Atlantic bottlenose dolphins (Tursiops truncatus) SO JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA LA English DT Article; Proceedings Paper CT 5th Animal Sonar Symposium CY SEP 14-18, 2009 CL Kyoto, JAPAN ID PHOCOENA-PHOCOENA; BEAM; HEAD; TRANSMISSION; BLUBBER; TISSUES; SIGNALS; LIPIDS; WHALE; MELON AB Arrays of up to six broadband suction cup hydrophones were placed on the forehead of two bottlenose dolphins to determine the location where the beam axis emerges and to examine how signals in the acoustic near-field relate to signals in the far-field. Four different array geometries were used; a linear one with hydrophones arranged along the midline of the forehead, and two around the front of the melon at 1.4 and 4.2 cm above the rostrum insertion, and one across the melon in certain locations not measured by other configurations. The beam axis was found to be close to the midline of the melon, approximately 5.4 cm above the rostrum insert for both animals.. The signal path coincided with the low-density, low-velocity core of the melon; however, the data suggest that the signals are focused mainly by the air sacs. Slight asymmetry in the signals were found with higher amplitudes on the right side of the forehead. Although the signal waveform measured on the melon appeared distorted, when they are mathematically summed in the far-field, taking into account the relative time of arrival of the signals, the resultant waveform matched that measured by the hydrophone located at 1 m.

The relationship between the functional demand on these tissues and metabolic substrate requirements is unknown. Using positron emission tomography (PET), relative cerebral blood flow was measured in a bottlenose dolphin. Approximately 60 mCi (13)NH(3) was administered to the dolphin via a catheter inserted into the hepatic vein and threaded proximate to the vena cava. Radio label initially appeared as distributed focal points in the cerebellum. Increasing scan time resulted in an increase in the number of focal regions and in the diffusivity of label activity throughout the brain. The time course and spatial distribution of radiolabel was consistent with a cerebral blood supply dominated by the spinal meningeal arteries. Blood flow was predominantly observed in the cerebellum and neocortex, particularly the auditory and visual cortex. Differential brain glucose uptake, previously measured in a separate dolphin, showed good agreement with the differential supply of blood to brain tissues. Rates of blood supply and glucose uptake in the auditory cortex, inferior colliculus, and cerebellum are consistent with a high metabolic demand of tissues which are important to the integration of auditory and other sensory inputs.

TI A method to enable a bottlenose dolphin (Tursiops truncatus) to echolocate while out of water SO JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA LA English DT Article; Proceedings Paper CT 5th Animal Sonar Symposium CY SEP 14-18, 2009 CL Kyoto, JAPAN ID MAGNETIC-RESONANCE IMAGES; 3-DIMENSIONAL RECONSTRUCTIONS; HEARING; SENSITIVITY; ANATOMY; TARGET; BRAIN; GENERATION; WHALE; HEAD AB The study of site-specific brain activity associated with dolphin echolocation has been hampered by the difficulties inherent in administering radiolabels and performing medical imaging while a dolphin echolocates in an aquatic environment. To overcome these limitations, a system has been developed to allow a bottlenose dolphin to echolocate while out of the water. The system relies on a "phantom echo generator" (PEG) consisting of a Texas Instruments C6713 digital signal processor with an analog input/output daughtercard. Echolocation clicks produced by the dolphin are detected with a hydrophone embedded in a suction cup on the melon, then digitized within the PEG. Clicks exceeding a user-defined threshold are convolved with a target impulse response, delayed, and scaled before being converted to analog and transmitted through a sound projector embedded in a suction cup attached to the dolphin's lower jaw. Dolphin in-air echolocation behavior, inter-click intervals, and overall performance were analogous to those observed during comparable underwater testing with physical targets, demonstrating that the dolphin was indeed performing an echolocation task while out of water.

Thus, the uptake of increased levels of atmospheric CO(2) by seawater, leading to reduced pH, has potential to change ambient noise levels. An important question is: By how much? Here, changes in ambient noise level due to hypothetical changes in seawater pH have been calculated at three receiver locations for years 1960 and 2250. The calculations used a range dependent propagation model that was applied to realistic environments based on climatology. Model results indicate changes in noise levels less than 0.21 dB are anticipated. C1 [Joseph, John E.; Chiu, Ching-Sang] USN, Postgrad Sch, Dept Oceanog, Monterey, CA 93943 USA.

The atmospheric behavior is found to be different between the two model configurations, and it is shown that the differences in the two simulations can be attributed to differences in the behavior of the zonal mean state of the stratosphere, where reflection of quasi-stationary resolved planetary waves from the lid of the low-top model is prominent; the more realistic physics in the high-top model is not relevant. It is also shown that downward propagation of zonal wind anomalies during weak stratospheric vortex events is substantially different in the two model configurations. These findings extend earlier results that a poorly resolved stratosphere can influence simulations throughout the troposphere.

The MgO-Y2O3 nanopowder was plasma sprayed using a conventional, DC arc plasma spray system. X-ray diffraction analysis shows that the as-sprayed MgO-Y2O3 coating is composed of cubic MgO and Y2O3 phases and has similar to 95% density. Microstructure characterization by SEM reveals that the as-sprayed coating has fine grain sizes of 100-300 nm as a result of rapid solidification. The hardness of the coating, 7.5 +/- A 0.6 GPa, is higher than that of coarse-grained, dense MgO, and Y2O3 ceramics. This approach demonstrates the potential of plasma spray processes for making thick, dense MgO-Y2O3 nanocomposite performs for applications as durable, infrared windows.

The gate current increases by one to two orders of magnitude at this bias, corresponding to an electric field strength around 1.8 MV cm(-1). The gate current increased by roughly five orders of magnitude after step-stressing the gate bias from 10 to 42 V in 1 V increments for 1 min at each bias. The drain current was also decreased by similar to 20% after this step-stress cycle. The photoluminescence and electroluminescence intensity from the semiconductor is decreased along the periphery of the gate region after stressing and transmission electron microscopy shows a thin native oxide layer under the gate and this disappears as the gate metal reacts with the underlying AlGaN.

A total of 31,184 chigger mites collected from 508 rodents and insectivores were slide-mounted and 10 species belonging to 4 genera were identified. Leptotrombidium pallidum (53.4%) was the most frequently collected, followed by L. palpale (15.7%), Neotrombicula tamiyai (14.3%), L. orientale (10.7%), L. zetum (3.1%), Walchia fragilis (2.1%), and L. gemiticulum (0.8%), while the remaining 3 species, L. subintermedium, N. gardellai, and Euschoengastia koreaensis were rarely observed (prevalence < 10%). In contrast to previous surveys, higher chigger indices of the primary scrub typhus vectors, L. pallidum (165.4), L. orientale (45.0), and L. palpale (21.4), were observed during the spring season.

Both of these equations are based on flux relations that were originally proposed as models of thermal wave phenomena, also known as second-sound. We then show how this method can be extended and used to obtain a particular type of exact solution to a class of nonlinear, hyperbolic PDEs. Published by Elsevier B.V. on behalf of IMACS.

TI Comet 81P/Wild 2: The size distribution of finer (sub-10 mu m) dust collected by the Stardust spacecraft SO METEORITICS & PLANETARY SCIENCE LA English DT Article ID TRANSMISSION ELECTRON-MICROSCOPY; ALUMINUM FOILS; HYPERVELOCITY IMPACT; MECHANICAL-BEHAVIOR; LABORATORY IMPACTS; PARTICLE-SIZE; STRAIN-RATE; CRATERS; RESIDUES; SIMULATION AB The fluence of dust particles < 10 mu m in diameter was recorded by impacts on aluminum foil of the NASA Stardust spacecraft during a close flyby of comet 81P/Wild 2 in 2004. Initial interpretation of craters for impactor particle dimensions and mass was based upon laboratory experimental simulations using projectiles less than > 10 mu m in diameter and the resulting linear relationship of projectile to crater diameter was extrapolated to smaller sizes. We now describe a new experimental calibration program firing very small monodisperse silica projectiles (470 nm-10 mu m) at approximately 6 km s-1. The results show an unexpected departure from linear relationship between 1 and 10 mu m. We collated crater measurement data and, where applicable, impactor residue data for 596 craters gathered during the postmission preliminary examination phase. Using the new calibration, we recalculate the size of the particle responsible for each crater and hence reinterpret the cometary dust size distribution. We find a greater flux of small particles than previously reported. From crater morphology and residue composition of a subset of craters, the internal structure and dimensions of the fine dust particles are inferred and a "maximum-size" distribution for the subgrains composing aggregate particles is obtained. The size distribution of the small particles derived directly from the measured craters peaks at approximately 175 nm, but if this is corrected to allow for aggregate grains, the peak in subgrain sizes is at < 100 nm.

The first case examines the impact of a hurricane-induced cold ocean wake on simulated changes in the structure of Hurricane Katrina. The second case investigates the effect of wind- and current-induced island wakes and their impact on the local electromagnetic (EM) and acoustic propagation characteristics in the Southern California Bight region. In the Katrina case, both the atmosphere and ocean show a strong response from air-sea interaction. The model results show that wind- induced turbulent mixing, vertical advection, and horizontal advection are the three primary causes of the development of the trailing cold ocean wake. A distinct spatial separation is seen in these three primary forcing terms that are generating the bulk of the cooling in the ocean mixed layer. An asymmetric tropical cyclone structure change has been documented in detail from a more realistic, full physics, and tightly coupled model. These changes include a broadening of the eye, a reduced radius of hurricane-force wind, and a pronounced inner-core dry slot on the west side of the storm. In the island wake experiment, many finescale variations in the wind, current, and static stability structure resulting from the two-way interaction are described. These variations take the form of narrow vorticity and temperature anomalies that are found to reside in the ocean and atmosphere well downwind from the Channel Islands. Upwind differences in the lower-atmospheric wind and thermal structure also arise and are found to have a small impact on the lee-flow structure and EM characteristics of the southernmost Channel Islands.

Calculations, based on density functional theory and enabled by adopting helical symmetry, show that F-terminated armchair ribbons are intrinsically twisted in helices, unlike flat H-terminated strips. Twisting ribbons of either termination couple the conduction and valence bands, resulting in band gap modulation. This electromechanical response could be exploited in switches and sensor applications. C1 [Gunlycke, Daniel; White, Carter T.] USN, Res Lab, Div Chem, Washington, DC 20375 USA.

This paper develops a two-stage stochastic optimization model to guide the allocation of budget to acquire and position relief assets, decisions that typically need to be made well in advance before a disaster strikes. The optimization focuses on minimizing the expected number of casualties, so our model includes first-stage decisions to represent the expansion of resources such as warehouses, medical facilities with personnel, ramp spaces, and shelters. Second-stage decisions concern the logistics of the problem, where allocated resources and contracted transportation assets are deployed to rescue critical population (in need of emergency evacuation), deliver required commodities to stay-back population, and transport the transfer population displaced by the disaster. Because of the uncertainty of the event's location and severity, these and other parameters are represented as scenarios. Computational results on notional test cases provide guidance on budget allocation and prove the potential benefit of using stochastic optimization.

Performance of these transducers has been investigated by analyzing the sources and effects of on-chip parasitic capacitances on the insertion-loss of the transducers. Modeling and experimental studies showed that on-chip parasitic capacitances degraded the performance of the transducers and an improved method of fabrication was suggested and new devices were built. New devices developed with minimal parasitic effects were shown to improve the performance significantly. A 1-mm aperture PVDF device developed with minimal parasitic effects has resulted in a reduction of insertion loss of 21 dB compared with devices fabricated using a previous method.

This model is suggested by the inverse gamma shape of the source exhibiting crossing legs of a rising flux loop and by evidence that the legs interact at or near the crossing point. The interaction is reflected by the location of peak brightness near the crossing point and by the formation of superimposed compact nonthermal sources most likely at or near the crossing point. These sources propagate upward along both legs, merge into a single, bright source at the top of the structure, and continue to rise at a velocity > 1000 km s(-1). The compact sources trap accelerated electrons which radiate in the radio and hard X-ray ranges. This suggests that they are plasmoids, although their internal structure is not revealed by the data. They exhibit variations of the radio brightness temperature at a characteristic time scale of similar to aEuro parts per thousand 40 s, anti-correlated to their area, which also support their interpretation as plasmoids. Their propagation path differs from the standard scenario of plasmoid formation and propagation in the flare current sheet, suggesting the helical current sheet formed by the instability instead.

Such a reconnection is complex, involving also the ambient field. In addition to breaking up the original rope, it can form a new, low-lying, less twisted flux rope. The new flux rope is pushed downward by the reconnection outflow, which typically forces it to break as well by reconnecting with the ambient field. The top part of the original rope, largely rooted in the sources of the ambient flux after the break-up, can fully erupt or be halted at low heights, producing a "failed eruption." The helical current sheet associated with the instability is squeezed between the approaching legs, temporarily forming a double current sheet. The leg -aEuro parts per thousand leg reconnection proceeds at a high rate, producing sufficiently strong electric fields that it would be able to accelerate particles. It may also form plasmoids, or plasmoid-like structures, which trap energetic particles and propagate out of the reconnection region up to the top of the erupting flux rope along the helical current sheet. The kinking of a highly twisted flux rope involving leg -aEuro parts per thousand leg reconnection can explain key features of an eruptive but partially occulted solar flare on 18 April 2001, which ejected a relatively compact hard X-ray and microwave source and was associated with a fast coronal mass ejection.

This may be attributed to the complexities in the classification, etiology, and physical examination of a patient with suspected posterior and multidirectional instability. Failure to address the primary and concurrent lesion adequately and the development of pain and/or stiffness are contributing factors to the failure of P-MDI procedures. Other pitfalls include errors in history and physical examination, failure to recognize concomitant pathology, and problems with the surgical technique or implant failure. Patulous capsular tissues and glenoid version also play in role management of failed P-MDI patients. With an improved understanding of pertinent clinical complaints and physical examination findings and the advent of arthroscopic techniques and improved implants, successful strategies for the nonoperative and operative management of the patient after a failed posterior or multidirectional instability surgery may be elucidated. This article highlights the common presentation, physical findings, and radiographic workup in a patient that presents after a failed P-MDI repair and offers strategies for revision surgical repair.

Computational analysis of an HAdV-C5 field strain genome, recovered from a patient with acute respiratory disease and coinfected with HAdV-B21, shows that there was no exchange of genomic material into HAdV-C5. Comparison of this genome to the sparsely amplified prototype demonstrates a high level of sequence conservation and stability of this genome across 45 years. Further, comparison to a version of the prototype that had been passaged in laboratory settings shows stability as well. HAdV genome stability and evolution are considerations for applications as vaccines and as vectors for gene delivery. In the annotation analysis, a single sequencing error in the HAdV-C5_ARM (Adenovirus Reference Material) genome is noted and may lead to erroneous annotation and biological interpretations.

The infinite domain is truncated via an artificial boundary B, and a high-order NRBC is applied on B. Numerical examples, in various configurations, concerning the propagation of a pressure pulse are used to demonstrate the performance of the SE implementation. Effects of time integration techniques and long term results are discussed. Specifically, we show that in order to achieve the full benefits of high-order accuracy requires balancing all errors involved: this includes the order of accuracy of the spatial discretization method, time-integrators, and boundary conditions.

CA STAR Collaboration TI Azimuthal di-hadron correlations in d plus Au and Au plus Au collisions at root s(NN)=200 GeV measured at the STAR detector SO PHYSICAL REVIEW C LA English DT Article ID AU+AU COLLISIONS; RADIATION; PLASMA AB Yields, correlation shapes, and mean transverse momenta p(T) of charged particles associated with intermediate-to high-p(T) trigger particles (2.5 < p(T) < 10 GeV/c) in d + Au and Au + Au collisions at root s(NN) = 200 GeV are presented. For associated particles at higher p(T) greater than or similar to 2.5 GeV/c, narrow correlation peaks are seen in d + Au and Au + Au, indicating that the main production mechanism is jet fragmentation. At lower associated particle pT < 2 GeV/c, a large enhancement of the near- (Delta phi similar to 0) and away-side (Delta phi similar to pi) associated yields is found, together with a strong broadening of the away-side azimuthal distributions in Au + Au collisions compared to d + Au measurements, suggesting that other particle production mechanisms play a role. This is further supported by the observed significant softening of the away-side associated particle yield distribution at Delta phi similar to pi in central Au + Au collisions. C1 [Aggarwal, M.

This paper shows that the change in the magnetic field strength B(t) was less abrupt than the plasma changes, and the fluctuations of the magnetic field strength in interval B were of moderate amplitude, with indications of a quasiperiodic structure in part of the interval. The magnetic field was directed away from the sun (positive polarity) similar to 78% +/- 5% of the time in both interval A and interval B, changing in an irregular way from positive to negative polarities throughout the interval. The polarity distribution indicates that the minimum latitudinal extent of the heliospheric current sheet (HCS) was near V2 throughout the interval, consistent with the extrapolated minimum latitudes of the HCS computed from solar magnetic field observations. Thus, V2 was observing magnetic fields from the southern polar coronal hole most of the time. The distribution of B was lognormal in interval A and Gaussian interval B. C1 [Burlaga, L.

TI A computationally compact representation of Magnetic-Apex and Quasi-Dipole coordinates with smooth base vectors SO JOURNAL OF GEOPHYSICAL RESEARCH-SPACE PHYSICS LA English DT Article ID HIGH-LATITUDES; SYSTEM; THERMOSPHERE; FIELD AB Many structural and dynamical features of the ionized and neutral upper atmosphere are strongly organized by the geomagnetic field, and several magnetic coordinate systems have been developed to exploit this organization. Quasi-Dipole coordinates are appropriate for calculations involving horizontally stratified phenomena like height-integrated currents, electron densities, and thermospheric winds; Modified Apex coordinates are appropriate for calculations involving electric fields and magnetic field-aligned currents. The calculation of these coordinates requires computationally expensive tracing of magnetic field lines to their apexes. Interpolation on a precomputed grid provides faster coordinate conversions, but requires the overhead of a sufficiently fine grid, as well as finite differencing to obtain coordinate base vectors. In this paper, we develop a compact and robust representation of the transformation from geodetic to Quasi-Dipole (QD), Apex, and Modified Apex coordinates, by fitting the QD coordinates to spherical harmonics in geodetic longitude and latitude. With this representation, base vectors may be calculated directly from the expansion coefficients. For an expansion truncated at order 6, the fitted coordinates deviate from the actual coordinates by a maximum of 0.4 degrees, and typically by 0.1 degrees. The largest errors occur in the equatorial Atlantic region. Compared to interpolation on a pre-computed grid, the spherical harmonic representation is much more compact and produces smooth base vectors. An algorithm for efficiently and concurrently computing scalar and vector spherical harmonic functions is provided in the appendix. Computer code for producing the expansion coefficients and evaluating the fitted coordinates and base vectors is included in the auxiliary material. C1 [Emmert, J. T.; Drob, D.

TI Amplification of the quasi-two day wave through nonlinear interaction with the migrating diurnal tide SO GEOPHYSICAL RESEARCH LETTERS LA English DT Article ID 2-DAY WAVE; MIDDLE ATMOSPHERE; MESOSPHERE; SUMMER; SABER; MODEL AB [1] We present a case study of the non-linear interaction between the quasi-two day wave (Q2DW) and the migrating diurnal tide based on global synoptic meridional wind fields for January 2006 and January 2008 from a high-altitude data assimilation/forecast system. We find large quasi-two day wave amplitudes, small diurnal tide amplitudes, and phase locking of the Q2DW with the diurnal cycle during January 2006. In January 2008 the amplitudes of the Q2DW were much smaller, with no evidence of phase locking, while the tidal amplitudes were larger than in the 2006 case. Space-time spectral analysis reveals an enhancement in a diurnal zonal wavenumber 6 feature in the January 2006 case, which can be attributed to a non-linear interaction between the Q2DW and migrating diurnal tide. The relatively strong summer easterly jet in the extratropical upper mesosphere during early January 2006 appears to have created conditions favoring this interaction. Citation: McCormack, J. P., S.

Measurements from instruments on the SOHO and TIMED spacecraft, and by suborbital rocket flights, indicate that solar extreme-ultraviolet irradiance levels were lower than they were during the previous solar minimum. Analysis of atmospheric drag on satellite orbits indicate that the thermosphere was lower in density, and therefore cooler, and than at any time since the beginning of the space age. However, secular change due to increasing levels of carbon dioxide and other greenhouse gases, which cool the upper atmosphere, also plays a role in thermospheric climate. Simulations by the NCAR Thermosphere-Ionosphere-Electrodynamics General Circulation Model are compared to thermospheric density measurements, yielding evidence that the primary cause of the low thermospheric density was the unusually low level of solar extreme-ultraviolet irradiance.

TI Coupling optical and electrical gating for electronic readout of quantum dot dynamics SO PHYSICAL REVIEW B LA English DT Article ID SINGLE-ELECTRON; TIME-DOMAIN; TRANSPORT; SPIN; OSCILLATIONS; CONDUCTANCE; MOLECULES; SYSTEM AB We explore the coherent transfer of electronic signatures from a strongly correlated, optically gated nanoscale quantum dot to a weakly interacting, electrically backgated microscale channel. In this unique side-coupled "T" geometry for transport, we predict a mechanism for detecting Rabi oscillations induced in the dot through quantum, rather than electrostatic means. This detection shows up directly in the dc conductance-voltage spectrum as a field-tunable split in the Fano lineshape arising due to interference between the dipole coupled dot states and the channel continuum. The split is further modified by the Coulomb interactions within the dot that influence the detuning of the Rabi oscillations. Furthermore, time resolving the signal we see clear beats when the Rabi frequencies approach the intrinsic Bohr frequencies in the dot. Capturing these coupled dynamics requires attention to memory effects and quantum interference in the channel as well as many-body effects in the dot. We accomplish this coupling by combining a Fock-space master equation for the dot dynamics with the phase-coherent, non-Markovian time-dependent nonequilibrium Green's function transport formalism in the channel through a properly evaluated self-energy and a Coulomb integral. The strength of the interactions can further be modulated using a backgate that controls the degree of hybridization and charge polarization at the transistor surface.

It is clear from the 2001 cases that survival may be markedly improved by administration of antimicrobial therapy during the early symptomatic phase of the illness; i. e., within 3 days of appearance of symptoms. Microbiological detection methods are feasible only for organisms that can be cultured in vitro and cannot detect all genetic modifications with the exception of antibiotic resistance. Currently available immuno or nucleic acid-based rapid detection assays utilize known, organism-specific proteins or genomic DNA signatures respectively. Hence, these assays lack the ability to detect novel natural variations or intentional genetic modifications that circumvent the targets of the detection assays or in the case of a biological attack using an antibiotic resistant or virulence enhanced Bacillus anthracis, to advise on therapeutic treatments. Methodology/ Principal Findings: We show here that the Roche 454-based pyrosequencing can generate whole genome draft sequences of deep and broad enough coverage of a bacterial genome in less than 24 hours. Furthermore, using the unfinished draft sequences, we demonstrate that unbiased identification of known as well as heretofore-unreported genetic modifications that include indels and single nucleotide polymorphisms conferring antibiotic and phage resistances is feasible within the next 12 hours. Conclusions/ Significance: Second generation sequencing technologies have paved the way for sequence-based rapid identification of both known and previously undocumented genetic modifications in cultured, conventional and newly emerging biothreat agents. Our findings have significant implications in the context of whole genome sequencing-based routine clinical diagnostics as well as epidemiological surveillance of natural disease outbreaks caused by bacterial and viral agents.

Last reported in Eurasia in 1963, this virus has since been conspicuously absent in broad surveys, and was never isolated in North America despite inclusion of specific tests for this serotype in surveillance methods. In 2006 and 2007, this virus suddenly emerged in North America, causing high attack rate epidemics of FRI and, in some cases, severe pneumonias and occasional fatalities. Some outbreaks have been relatively mild, with low rates of progression beyond uncomplicated FRI, while other outbreaks have involved high rates of more serious outcomes. Methodology and Findings: In this paper we present the complete genomic sequence of this emerging pathogen, and compare genomic sequences of isolates from both mild and severe outbreaks. We also compare the genome sequences of the recent isolates with those of the prototype HAdV-14 that circulated in Eurasia 30 years ago and the closely related sequence of HAdV-11a, which has been circulating in southeast Asia. Conclusions: The data suggest that the currently circulating strain of HAdV-14 is closely related to the historically recognized prototype throughout its genome, though it does display a couple of potentially functional mutations in the fiber knob and E1A genes. There are no polymorphisms that suggest an obvious explanation for the divergence in severity between outbreak events, suggesting that differences in outcome are more likely environmental or host determined rather than viral genetics.

Since CD8+ T cell responses have been implicated in protection against pre-erythrocytic stage malaria, this study was designed to identify MHC class I-restricted epitopes within AMA1. Methods: A recombinant adenovirus serotype 5 vector expressing P. falciparum AMA1 was highly immunogenic when administered to healthy, malaria-naive adult volunteers as determined by IFN-gamma ELISpot responses to peptide pools containing overlapping 15-mer peptides spanning full-length AMA1. Computerized algorithms (NetMHC software) were used to predict minimal MHC-restricted 8-10-mer epitope sequences within AMA1 15-mer peptides active in ELISpot. A subset of epitopes was synthesized and tested for induction of CD8+ T cell IFN-gamma responses by ELISpot depletion and ICS assays. A 3-dimensional model combining Domains I + II of P. falciparum AMA1 and Domain III of P. vivax AMA1 was used to map these epitopes. Results: Fourteen 8-10-mer epitopes were predicted to bind to HLA supertypes A01 (3 epitopes), A02 (4 epitopes), B08 (2 epitopes) and B44 (5 epitopes). Nine of the 14 predicted epitopes were recognized in ELISpot or ELISpot and ICS assays by one or more volunteers. Depletion of T cell subsets confirmed that these epitopes were CD8+ T cell-dependent. A mixture of the 14 minimal epitopes was capable of recalling CD8+ T cell IFN-gamma responses from PBMC of immunized volunteers. Thirteen of the 14 predicted epitopes were polymorphic and the majority localized to the more conserved front surface of the AMA1 model structure. Conclusions: This study predicted 14 and confirmed nine MHC class I-restricted CD8+ T cell epitopes on AMA1 recognized in the context of seven HLA alleles. These HLA alleles belong to four HLA supertypes that have a phenotypic frequency between 23% - 100% in different human populations.

Lindner, Netanel Rudolph, Terry TI Optically Generated 2-Dimensional Photonic Cluster State from Coupled Quantum Dots SO PHYSICAL REVIEW LETTERS LA English DT Article ID COMPUTER; SPIN AB We propose a method to generate a two-dimensional cluster state of polarization encoded photonic qubits from two coupled quantum dot emitters. We combine the proposal for generating one-dimensional cluster state strings from a single dot, with a new proposal for an induced conditional phase gate between the two quantum dots. The entanglement between the two dots translates to entanglement between the two photonic cluster state strings. Further interpair coupling of the quantum dots using cavities and wave-guides can lead to a two-dimensional cluster sheet, the importance of which stems from the fact that it is a universal resource for quantum computation. Analysis of errors indicates that our proposal is feasible with current technology. Crucially, the emitted photons need not have identical frequencies, and so there are no constraints on the resonance energies for the quantum dots.

The Shigella flexneri Invaplex 50 is a macromolecular complex containing IpaB, IpaC, and LPS, formulated from an aqueous extract of virulent Shigella delivered via nasal administration. Preclinical vaccine testing demonstrated safety, immunogenicity and efficacy. An open-label dose-escalating phase 1 study evaluated a 3-dose (2-week intervals) regimen via nasal pipette delivery. Thirty-two subjects were enrolled into one of four vaccine dose groups (10, 50,240, or 480 mu g). The vaccine was well tolerated with minor short-lived nasal symptoms without evidence of dose effect. Antibody-secreting cell (ASC) responses were elicited at doses >= 50 mu g with the highest IgG ASC, Invaplex 50 (100%) and S. flexneri 2a LPS (71%), as well as, serologic responses (43%) occurring with the 240 mu g dose. Fecal IgA responses, Invaplex 50(38.5%) and LPS (30.8%), were observed at doses >= 240 mu g. The Invaplex 50 nasal vaccine was safe with encouraging mucosal immune responses. Follow-on studies will optimize dose, delivery mechanism and assess efficacy in a S. flexneri 2a challenge study. Published by Elsevier Ltd.

TI Using conformationally locked nucleosides to calibrate the anomeric effect: implications for glycosyl bond stability SO TETRAHEDRON LA English DT Article ID PSEUDOROTATIONAL EQUILIBRIUM; PENTOFURANOSE MOIETY; ALCOHOLS; H-1-NMR; SYSTEM AB Steric and electronic parameters, such as the anomeric effect (AE) and gauche effect play significant roles in steering the North <-> South equilibrium of nucleosides in solution. Two isomeric oxa-bicyclo[3.1.0]hexane nucleosides that are conformationally locked in either the North or the South conformation of the pseudorotational cycle were designed to study the consequences of having the AE operational or not, independent of other parameters. The rigidity of the system allowed the orientation of the orbitals involved to be set in 'fixed' relationships, either antiperiplanar where the AE is permanently 'on', or gauche where the AE is impaired. The consequences of these two alternatives were subjected to high-level calculations and measured experimentally by X-ray crystallography, hydrolytic stability of the glycosyl bond, and pK(a) values.

TI WHITE LIGHT AND IN SITU COMPARISON OF A FORMING MERGED INTERACTION REGION SO ASTROPHYSICAL JOURNAL LA English DT Article DE solar-terrestrial relations; solar wind; Sun: coronal mass ejections (CMEs) ID CORONAL MASS EJECTION; MAGNETIC CLOUD EXPANSION; STEREO MISSION; SOLAR-WIND; HELIOSPHERIC IMAGERS; 1 AU; SECCHI; BRIGHTNESS; TRACKING; EARTH AB The images taken by the Heliospheric Imager (HI) instruments, part of the SECCHI imaging package on board the pair of STEREO spacecraft, provide information on the radial and latitudinal evolution of the plasma transported by coronal mass ejections (CMEs). In this case study, a CME, appearing near 15 UT on 2007 November 15 in SECCHI coronagraph images, leads to the formation of two out-flowing density structures (DSs) in the heliosphere. The analysis of time-elongation maps constructed from images obtained by the HI instruments shows that these DSs were propagating along the Sun-Earth line. A direct comparison of HI images and in situ measurements taken near Earth could therefore be performed. These two DSs are separated by a cavity associated with little brightness variation or equivalently little electron density variation. In situ measurements made in the solar wind near Earth on 2007 November 20 show that this cavity corresponds to a magnetic cloud (MC). While the leading DS is related to the sheath in front of the MC, the second DS is located on the sunward side of the MC where high-speed solar wind from a coronal hole catches up and interacts with the MC. We conclude that HI observes the sub-structures of a merged interaction region (MIR), a region of the interplanetary medium where the total solar wind pressure is greatly enhanced by the interaction of an MC with the ambient solar wind. This MIR caused the largest geomagnetic storm in 2007. C1 [Rouillard, A. P.; Lavraud, B.; Jacquey, C.] Univ Toulouse, Ctr Etud Spatiale Rayonnements, F-21028 Toulouse, France. [Rouillard, A.

TI FERMI LARGE AREA TELESCOPE VIEW OF THE CORE OF THE RADIO GALAXY CENTAURUS A SO ASTROPHYSICAL JOURNAL LA English DT Article DE galaxies: active; galaxies: individual (Centaurus A); galaxies: jets; gamma rays: galaxies; radiation mechanisms: non-thermal ID GAMMA-RAY EMISSION; ACTIVE GALACTIC NUCLEI; ENERGY COSMIC-RAYS; SUPERMASSIVE BLACK-HOLE; BASE-LINE INTERFEROMETRY; BL LACERTAE OBJECTS; X-RAY; PARTICLE-ACCELERATION; TEV BLAZARS; NGC 5128 AB We present gamma-ray observations with the Large Area Telescope (LAT) on board the Fermi Gamma-Ray Space Telescope of the nearby radio galaxy Centaurus A (Cen A). The previous EGRET detection is confirmed, and the localization is improved using data from the first 10 months of Fermi science operation. In previous work, we presented the detection of the lobes by the LAT; in this work, we concentrate on the gamma-ray core of Cen A. Flux levels as seen by the LAT are not significantly different from that found by EGRET, nor is the extremely soft LAT spectrum (Gamma = 2.67 +/- 0.10(stat) +/- 0.08(sys) where the photon flux is Phi alpha E-Gamma). The LAT core spectrum, extrapolated to higher energies, is marginally consistent with the non-simultaneous HESS spectrum of the source. The LAT observations are complemented by simultaneous observations from Suzaku, the Swift Burst Alert Telescope and X-ray Telescope, and radio observations with the Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry program, along with a variety of non-simultaneous archival data from a variety of instruments and wavelengths to produce a spectral energy distribution (SED). We fit this broadband data set with a single-zone synchrotron/synchrotron self-Compton model, which describes the radio through GeV emission well, but fails to account for the non-simultaneous higher energy TeV emission observed by HESS from 2004 to 2008. The fit requires a low Doppler factor, in contrast to BL Lac objects which generally require larger values to fit their broadband SEDs. This indicates that the gamma-ray emission originates from a slower region than that from BL Lac objects, consistent with previous modeling results from Cen A. This slower region could be a slower moving layer around a fast spine, or a slower region farther out from the black hole in a decelerating flow. The fit parameters are also consistent with Cen A being able to accelerate ultra-high energy cosmic-rays, as hinted at by results from the Auger observatory. C1 [Abdo, A.

These whirling motions often persist in the same sense for up to several days and provide strong evidence that the cavities and the immediately surrounding streamer material have the form of helical flux ropes viewed along their axes. A pronounced bias toward spin in the equatorward direction is observed during 2008. We attribute this bias to the poleward concentration of the photospheric magnetic flux near sunspot minimum, which leads to asymmetric heating along large-scale coronal loops and tends to drive a flow from higher to lower latitudes; this flow is converted into an equatorward spinning motion when the loops pinch off to form a flux rope. As sunspot activity increases and the polar fields weaken, we expect the preferred direction of the spin to reverse.

TI Measurement of polarisation-dependent phase shift in DPSK demodulator SO ELECTRONICS LETTERS LA English DT Article ID FIBER-OPTIC SENSORS; PHOTONIC LINKS; NOISE AB The recent availability of DPSK demodulators has spurred interest in phase-modulated analogue RF photonic links, but phase shifts due to birefringence can cause transmission impairments. Presented are measurements of the polarisation-dependent phase shift in a DPSK demodulator created by the relative angle (in Stokes space) between the launch SOP and the demodulator's eigenstate. This phase shift is connected to earlier theoretical predictions, and results are compared to a vendor's specifications for three models. Since imperfect phase modulators may cause modulation of the polarisation at the signal frequency, these impairments may limit RF photonic link performance. C1 [Frigo, N.

Analysis of RADARSAT-2 (R2) quad-polarization (quad-pol) data with collocated in situ ocean wind measurements reveals that the de-pol radar backscatter does not saturate in high winds. This is a significant development for radar wind sensing, because wind retrieval with copolarized (co-pol) backscatter suffers from problems of incidence-and-azimuth-angle-dependent signal saturation and dampening in high winds. We present a study comparing satellite quad-pol measurements with the composite surface Bragg (CB) theory of radar backscattering from the ocean surface. The co-pol data are in good agreement with the CB theory. De-pol data are more sensitive to wind speed compared to theoretical prediction, thus retrieval of high winds is more accurate using the de-pol return. The cubic wind speed dependence of de-pol returns in high winds reflects the significant breaking wave contributions. The relationship can be used to obtain wave-breaking properties from space.

The QDs were prepared starting from CdSe-ZnS core shell QDs surface-capped with carboxy-functionalized poly(ethylene glycol) (PEG) ligands. This modification allowed coupling of a controllable number of oligohistidine-tagged proteins via metal-affinity interactions. In particular, QD-Ni-NTA complexes were coupled to 5 x His-tagged maltose binding proteins labeled with Texas red, where effective formation of the QD-MBP-Texas red conjugates was confirmed by agarose gel electrophoresis and fluorescence resonance energy transfer studies. The stability of the QD-MBP conjugates was further tested inside live cells following microinjection directly into the cytoplasm. This design expands on the good colloidal stability afforded by our earlier PEG-based modular ligands which provided QDs with great colloidal stability over a broad range of biologically relevant conditions.

An adsorbed layer of pyruvic acid (PA) was successfully formed on Ga2O3 NWs by simple room temperature vapor transport, which was confirmed by Fourier transform infrared spectroscopy. The effect of the adsorbed PA on the surface properties was demonstrated by the change in the response of the NW gas-sensing devices. Results indicate that the adsorption of PA reduced the sensitivity of the Ga2O3 NW device to common hydrocarbons such as nitromethane and acetone while improving the response to triethylamine by an order of magnitude. Taking into account the simplicity of this functionalization together with the ease of producing these capacitance-based gas-sensing devices, this approach represents a viable technique for sensor development.

TI HLA B*44 Protective effects in MS susceptibility and MRI outcome SO NEUROLOGY LA English DT Article ID MULTIPLE-SCLEROSIS SUSCEPTIBILITY; CLASS-I REGION; HLA-A; DISEASE SEVERITY; GENES; POPULATION; DISABILITY; RISK; HLA-DRB1-ASTERISK-1501; ASSOCIATION AB Objective: In addition to the main multiple sclerosis (MS) major histocompatibility complex (MHC) risk allele (HLA DRB1*1501), investigations of the MHC have implicated several class I MHC loci (HLA A, HLA B, and HLA C) as potential independent MS susceptibility loci. Here, we evaluate the role of 3 putative protective alleles in MS: HLA A*02, HLA B*44, and HLA C*05. Methods: Subjects include a clinic-based patient sample with a diagnosis of either MS or a clinically isolated syndrome (n = 532), compared to subjects in a bone marrow donor registry (n = 776). All subjects have 2-digit HLA data. Logistic regression was used to determine the independence of each allele's effect. We used linear regression and an additive model to test for correlation between an allele and MRI and clinical measures of disease course. Results: After accounting for the effect of HLA DRB1*1501, both HLA A*02 and HLA B*44 are validated as susceptibility alleles (p A*02 0.00039 and p B*44 0.00092) and remain significantly associated with MS susceptibility in the presence of the other allele. Although A*02 is not associated with MS outcome measures, HLA B*44 demonstrates association with a better radiologic outcome both in terms of brain parenchymal fraction and T2 hyperintense lesion volume (p = 0.03 for each outcome). Conclusion: The MHC class I alleles HLA A*02 and HLA B*44 independently reduce susceptibility to MS, but only HLA B*44 appears to influence disease course, preserving brain volume and reducing the burden of T2 hyperintense lesions in subjects with MS.

A thermal-excitation model of "hot" injected electrons from the upper laser state to upper active-region states is used to calculate leakage currents. The calculated characteristic temperature T(0) for J(th) is found to agree well with experiment for both conventional and deep-well (DW) QCLs. For conventional QCLs eta(wp,max) is found to be strongly temperature dependent; explaining experimental data. At 300 K for optimized DW-QCLs, front-facet, continuous-wave eta(wp,max) values >20% are projected. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3478836] C1 [Botez, D.; Shin, J.

Optical intensity waveforms exhibiting complementary modulation are synthesized via polarization pulse shaping; balanced photodetection is then utilized to suppress the waveform pedestal in the electrical domain.

TI On the driving force for recombination-induced stacking fault motion in 4H-SiC SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID ENHANCED DISLOCATION GLIDE; PIN DIODES; SINGLE-CRYSTALS; LUMINESCENCE; DEFECTS; DEVICES AB The formation and expansion of recombination-induced stacking faults (SFs) within 4H-SiC bipolar and unipolar devices is known to induce a drift in the forward voltage during forward bias operation. This drift renders devices unsuitable for commercial applications. While the expansion of SFs in 4H-SiC occurs by the recombination-enhanced dislocation glide mechanism, why SF expansion occurs, i.e., the energetic driving force, remains unclear. Recent experiments have revealed that SF contraction and a recovery of the forward voltage drift can be induced under many conditions, including forward bias operation. Such observations have enabled the identification of SF-related degradation in devices where imaging methods are not possible and are inconsistent with the previously reported energetic driving force models. We present a model that qualitatively explains these recent experimental observations, which is based on the quasi-Fermi energy of the electron population during forward bias operation. Device simulation results and further experiments are also reported in support of this model.

A Diamond secondary emitter used in conjunction with a photocathode and drive laser has potential to enable a high brightness, high peak current photoinjector by increasing the effective quantum efficiency of the photocathode. A theoretical characterization of the bunches so produced has been heretofore absent. Using a combination of Monte Carlo and analytical models, the shape of the bunches, their transit time, and emission time constants are determined and shown to be sensitive to the accelerating field in the diamond flake, incident beam profile, doping, and surface conditions. Methods to allow for extension to regimes of technological interest in terms of diamond thickness, external field, and primary pulse shape are given. (C) 2010 American Institute of Physics.

Slutsky, Jonathan Bettridge, Shannon TI Hydrodynamics of a ship/whale collision SO JOURNAL OF EXPERIMENTAL MARINE BIOLOGY AND ECOLOGY LA English DT Article DE Hydrodynamics; Ship strike; Whale/vessel collisions ID ATLANTIC RIGHT WHALES; VESSEL SPEED; MORTALITY; SHIPS; RISK AB All endangered large whale species are vulnerable to collisions with large ships: and "ship strikes" are the greatest known threat to one of the world's rarest whales, the North Atlantic right whale (Eubalaena glacialis). The magnitude of this threat is likely to increase as maritime commerce expands. Factors influencing the incidence and severity of ship strikes are not well understood, although vessel speed appears to be a strong contributor. The purpose of this study was to characterize the hydrodynamic effects near a moving hull that may cause a whale to be drawn to or repelled from the hull, and to assess the accelerations exerted on a whale at the time of impact. Using scale models of a container ship and a right whale in experimental flow tanks, we assessed hydrodynamic effects and measured accelerations experienced by the whale model in the presence of a moving vessel. Accelerations at impact were measured while the whale was at the surface, for various vessel speeds, orientations of the whale relative to the vessel path, and distances off the direct path of the vessel. Accelerations experienced by the whale model in a collision: increased in magnitude with increasing ship speed: were not dependent on whale orientation to the vessel path: and decreased exponentially with increasing separation distances from the ship track. Subsequent experiments with the whale model submerged at one to two times the ship's draft indicated a pronounced propeller suction effect, a drawing of the whale toward the hull, and increased probability of propeller strikes resulting from this class of encounter. Measured accelerations are a proxy for impact severity, but do not constitute a detailed study of injury mechanism in a living animal, though they may help inform future work. We present a heuristic map of the hydrodynamic field around a transiting hull likely involved in close whale/vessel encounters. These results may have bearing on policy decisions, particularly those involving vessel speed, aimed at protecting large whales from ship strikes worldwide. Published by Elsevier B.V.

TI Theoretical Implications of the Elastic Modulus Discontinuity in Rubber Networks SO JOURNAL OF POLYMER SCIENCE PART B-POLYMER PHYSICS LA English DT Article DE elastomers; strain; stress; theory ID LINKED NATURAL-RUBBER; SMALL-STRAIN BEHAVIOR; POLY(DIMETHYLSILOXANE); COMPRESSIONS; EXTENSION; STRESS; RANGE AB The existence of a discontinuity in the modulus of rubber as the strain transitions from compression to extension is strongly suggested by multiple experiments. Classical rubber elasticity theories, however, do not admit such behavior. Here, we investigate a modification of the assumptions of classical elasticity theory to reconcile this discrepancy. We present an analysis of the consequences of assuming that chain forces are nonzero only for chain extension relative to the unstrained state, in contrast to the classical elasticity theory, which assumes that the chain force is directly proportional to the chain end-to-end distance (an entropic spring). Assuming an affine transformation of the network node coordinates, we derive two modulus discontinuity factors between compression and extension: D(1), based on the differing number of network chains being extended and D(2), based on the average differential chain extension. The discontinuities arise due to geometric effects, inherent in the affine transformation between compressive and extensive strains. We find that D(1), the ratio of the numbers of participating chains (compressive/extensive = 1.37), suffices to account for the experimentally observed modulus discontinuity in natural rubber of 1.34.

CA STAR Collaboration TI Balance functions from Au+Au, d+Au, and p+p collisions at root s(NN)=200 GeV SO PHYSICAL REVIEW C LA English DT Article ID HEAVY-ION COLLISIONS; AU-AU COLLISIONS; TIME PROJECTION CHAMBER; BY-EVENT FLUCTUATIONS; QUARK-GLUON PLASMA; TRANSVERSE-MOMENTUM; MEAN-P(T) FLUCTUATIONS; MODEL; HADRONIZATION; SIGNATURES AB Balance functions have been measured for charged-particle pairs, identified charged-pion pairs, and identified charged-kaon pairs in Au + Au, d + Au, and p + p collisions at root s(NN) = 200 GeV at the Relativistic Heavy Ion Collider using the STAR detector. These balance functions are presented in terms of relative pseudorapidity, Delta eta, relative rapidity, Delta y, relative azimuthal angle, Delta phi, and invariant relative momentum, q(inv). For charged-particle pairs, the width of the balance function in terms of Delta eta scales smoothly with the number of participating nucleons, while HIJING and UrQMD model calculations show no dependence on centrality or system size. For charged-particle and charged-pion pairs, the balance functions widths in terms of Delta eta and Delta y are narrower in central Au + Au collisions than in peripheral collisions. The width for central collisions is consistent with thermal blast-wave models where the balancing charges are highly correlated in coordinate space at breakup. This strong correlation might be explained by either delayed hadronization or limited diffusion during the reaction. Furthermore, the narrowing trend is consistent with the lower kinetic temperatures inherent to more central collisions. In contrast, the width of the balance function for charged-kaon pairs in terms of Delta y shows little centrality dependence, which may signal a different production mechanism for kaons. The widths of the balance functions for charged pions and kaons in terms of q(inv) narrow in central collisions compared to peripheral collisions, which may be driven by the change in the kinetic temperature.

Skirlo, Scott TI Spatial resolution of a hard x-ray CCD detector SO APPLIED OPTICS LA English DT Article ID POWER AB The spatial resolution of an x-ray CCD detector was determined from the widths of the tungsten x-ray lines in the spectrum formed by a crystal spectrometer in the 58 to 70 keV energy range. The detector had 20 mu m pixel, 1700 by 1200 pixel format, and a CsI x-ray conversion scintillator. The spectral lines from a megavolt x-ray generator were focused on the spectrometer's Rowland circle by a curved transmission crystal. The line shapes were Lorentzian with an average width after removal of the natural and instrumental line widths of 95 mu m (4.75 pixels). A high spatial frequency background, primarily resulting from scattered gamma rays, was removed from the spectral image by Fourier analysis. The spectral lines, having low spatial frequency in the direction perpendicular to the dispersion, were enhanced by partially removing the Lorentzian line shape and by fitting Lorentzian curves to broad unresolved spectral features. This demonstrates the ability to improve the spectral resolution of hard x-ray spectra that are recorded by a CCD detector with well-characterized intrinsic spatial resolution.

TI COORDINATED ANALYSES OF PRESOLAR GRAINS IN THE ALLAN HILLS 77307 AND QUEEN ELIZABETH RANGE 99177 METEORITES SO ASTROPHYSICAL JOURNAL LA English DT Article DE circumstellar matter; dust, extinction; nuclear reactions, nucleosynthesis, abundances; stars: AGB and post-AGB; stars: winds, outflows; supernovae: general ID ASYMPTOTIC GIANT BRANCH; SILICON-CARBIDE GRAINS; TITANIUM ISOTOPIC COMPOSITIONS; GALACTIC CHEMICAL EVOLUTION; CIRCUMSTELLAR GRAPHITE GRAINS; INTERPLANETARY DUST PARTICLES; SIC GRAINS; CARBONACEOUS CHONDRITES; MURCHISON METEORITE; INTERSTELLAR-MEDIUM AB We report the identification of presolar silicates (similar to 177 ppm), presolar oxides (similar to 11 ppm), and one presolar SiO(2) grain in the Allan Hills (ALHA) 77307 chondrite. Three grains having Si-isotopic compositions similar to SiC X and Z grains were also identified, though the mineral phases are unconfirmed. Similar abundances of presolar silicates (similar to 152 ppm) and oxides (similar to 8 ppm) were also uncovered in the primitive CR chondrite Queen Elizabeth Range (QUE) 99177, along with 13 presolar SiC grains and one presolar silicon nitride. The O-isotopic compositions of the presolar silicates and oxides indicate that most of the grains condensed in low-mass red giant and asymptotic giant branch stars. Interestingly, unlike presolar oxides, few presolar silicate grains have isotopic compositions pointing to low-metallicity, low-mass stars (Group 3). The (18)O-rich (Group 4) silicates, along with the few Group 3 silicates that were identified, likely have origins in supernova outflows. This is supported by their O- and Si-isotopic compositions. Elemental compositions for 74 presolar silicate grains were determined by scanning Auger spectroscopy. Most of the grains have non-stoichiometric elemental compositions inconsistent with pyroxene or olivine, the phases commonly used to fit astronomical spectra, and have comparable Mg and Fe contents. Non-equilibrium condensation and/or secondary alteration could produce the high Fe contents. Transmission electron microscopic analysis of three silicate grains also reveals non-stoichiometric compositions, attributable to non-equilibrium or multistep condensation, and very fine scale elemental heterogeneity, possibly due to subsequent annealing. The mineralogies of presolar silicates identified in meteorites thus far seem to differ from those in interplanetary dust particles.

This constitutes the largest continuous X-ray-monitoring data set analyzed to date for this source. Such an extended analysis allows us to report (1) the discovery of variability in the orbital profiles of the X-ray emission, (2) the existence of a few (recent) short flares on top of the overall behavior typical of the source, which, given the PCA field of view, may or may not be associated with LS I + 61. 303, and (3) the determination of the orbital periodicity using soft X-ray data alone.

This airglow occurred during an experiment at twilight from 02551600 UT (1855-2000 LT) and with estimated scale sizes of 100 m (at assumed 225 km altitude) constitutes the smallest structure observed in artificial airglow to date. The rays appeared to be oriented along the geomagnetic field lines. During this period, other instruments, SuperDARN, GPS receivers, stimulated electromagnetic emissions receivers, also recorded unusual data sets with the general characteristic of time scales longer than anticipated for features to form. The experiment took place at the commencement of a small geomagnetic disturbance (Kp of 4.3). This unique observation is as yet unexplained. The airglow features start as large scale structures and then become smaller as heating continues in apparent contradiction to current theories on irregularity development. A thermal gradient instability at boundary of the ionospheric footprint of the plasmapause may be responsible for causing the small-scale structuring. Observations of 427.8 nm N-2(+) (first negative group) emissions indicate the presence of ionization. C1 [Kendall, Elizabeth] SRI Int, Menlo Pk, CA 94025 USA.

TI Directly measured heating rates of a tropical subvisible cirrus cloud SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article ID RADIATIVE PROPERTIES; ACCURATE PARAMETERIZATION; LIDAR MEASUREMENTS; CLIMATE MODELS; TROPOPAUSE; THIN; IMPACT; STRATOSPHERE; TROPOSPHERE; AEROSOL AB We present the first direct measurements of the infrared and solar heating rates of a tropical subvisible cirrus (SVC) cloud sampled off the east coast of Nicaragua on 25 July 2007 by the NASA ER-2 aircraft during the Tropical Composition, Cloud and Climate Coupling Experiment (TC4). On this day a persistent thin cirrus layer, with mostly clear skies underneath, was detected in real time by the cloud lidar on the ER-2, and the aircraft was directed to profile down through the SVC. Measurements of the net broadband infrared irradiance and spectrally integrated solar irradiance above, below, and through the SVC are used to determine the infrared and solar heating rates of the cloud. The lidar measurements show that the variable SVC layer was located between similar to 13 and 15 km. Its midvisible optical depth varied from 0.01 to 0.10 with a mean of 0.034 +/- 0.033. Its depolarization ratio was approximately 0.4, indicative of ice clouds. From the divergence of the measured net irradiances the infrared heating rate of the SVC was determined to be similar to 2.50-3.24 K d(-1) and the solar heating rate was found to be negligible. These values are consistent with previous indirect observations of other SVC and with model-generated heating rates of SVC with similar optical depths. This study illustrates the utility and potential of the profiling sampling strategy employed here. A more fully instrumented high-altitude aircraft that also included in situ cloud and aerosol probes would provide a comprehensive data set for characterizing both the radiative and microphysical properties of these ubiquitous tropical clouds.

The effects of temperature and field, which affect the electron distribution and transmission probability, respectively, of electrons incident on the surface barrier, are found. The resulting formulations of emittance are compared to the asymptotic limit found by D. H. Dowell and J.F. Schmerge [Phys. Rev. ST Accel.

TI Salt transport in the near-surface layer in the monsoon-influenced Indian Ocean using HYCOM SO GEOPHYSICAL RESEARCH LETTERS LA English DT Article ID MIXED-LAYER; SALINITY; SEA AB Salt advection in the top 5 m layer of the monsoon-influenced Indian Ocean has been studied with high resolution HYbrid Coordinate Ocean Model (HYCOM) simulated sea surface salinity (SSS) during 2003-06. The effect of monsoon reversals and roles of Ekman drift and geostrophic currents are emphasized. The Ekman drift component is found to be more important than the geostrophic component in exchange of salt in the basins; an indication of the influence of winds and the associated surface currents. The strongest differences in the salt advection terms occurred in the Bay of Bengal (BoB), an indication of the significant role of advection for the distribution of freshwater and the Ekman processes. The Inter-Tropical Convergence Zone (ITCZ) is seen to influence advection patterns via Ekman drift along the equatorial region. This results in the creation of two salt advection bands whose positions vary seasonally. This study will help to interpret data from the recently launched Soil Moisture Ocean Salinity (SMOS) and future Aquarius salinity missions for the Indian Ocean. Citation: Nyadjro, E. S., B.

TI Tight-binding Hamiltonian for LaOFeAs SO PHYSICAL REVIEW B LA English DT Article ID SUPERCONDUCTIVITY AB First-principles electronic-structure calculations have been very useful in understanding some of the properties of the new iron-based superconductors. Further explorations of the role of the individual atomic orbitals in explaining various aspects of research in these materials, including experimental work, would benefit from the availability of a tight-binding (TB) Hamiltonian that accurately reproduces the first-principles band-structure results. In this work we have used the Naval Research Laboratory-TB method to construct a TB Hamiltonian from linearized augmented plane wave (LAPW) results. Our TB model includes the Fe d orbitals and the p orbitals from both As and O for the prototype material LaOFeAs. The resulting TB band structure agrees well with that of the LAPW calculations from 2.7 eV below to 0.8 eV above the Fermi level, epsilon(F), and the Fermi surface matches perfectly to that of the LAPW. The TB densities of states (DOSs) are also in very good agreement with those from the LAPW in the above energy range, including the per orbital decomposition. We use our results to provide insights on the existence of a pseudogap in the DOS just above the Fermi level. We have also performed a separate TB fit to a database of LAPW results as a function of volume and with variations in the As positions. This fit although less accurate regarding the band structure near epsilon(F), reproduces the LAPW total energies very well and has transferability to nonfitted energies. C1 [Papaconstantopoulos, D.

We introduce a graphical retrieval method and phase unwrapping techniques. The graphical method utilizes the linear regression technique. Our method can reduce the uncertainty of experimental measurements and the ambiguity of phase unwrapping. Moreover, the graphical method can simultaneously determine the bulk values of the six effective material parameters, permittivity and permeability tensors, from a single layer of unit cells.

The results show that the post-anneal Schottky barrier height (SBH) increased with increasing annealing temperature, reaching a peak increase of 43% at 500 degrees C. A further increase in the anneal temperature above 500 degrees C degraded the SBH. The ideality factor displayed a weak dependence on post-annealing temperature until rising dramatically at a post-annealing temperature of 600 degrees C. The degradation at 600 degrees C post-annealing temperature can be attributed to the formation of Nickel-Gallides. In-situ current-voltage characteristics obtained between 15 degrees C and 165 degrees C revealed that both the ideality factor and SBH were stable up to 165 degrees C with increasing in-situ measurement temperature.

ED crowding not only is associated with poorer patient outcomes, but it also contributes to lost demand for ED services when patients leave without being seen and hospitals must go on ambulance diversion. However, somewhat paradoxically, ED crowding may financially benefit hospitals. This is because ED crowding allows hospitals to maximize occupancy with well-insured, elective patients while patients wait in the ED. In this article, the authors propose a more holistic model of hospital flow and revenue that contradicts this notion and offer suggestions for improvements in ED and hospital management that may not only reduce crowding and improve quality, but also increase hospital revenues. Also proposed is that increased efficiency and quality in U.S. hospitals will require changes in systematic microeconomic and macroeconomic incentives that drive the delivery of health services in the United States. Finally, the authors address several questions to propose mutually beneficial solutions to ED crowding that include the realignment of hospital incentives, changing culture to promote flow, and several ED-based strategies to improve ED efficiency.

TI The Cost of Pursuing a Medical Career in the Military: A Tale of Five Specialties SO ACADEMIC MEDICINE LA English DT Article ID PHYSICIAN WORKFORCE; STATES AB Purpose The physician payment system is a focus of potential reform in the United States. The authors explored the effects of the military's method of physician payment on physicians' returns on educational investment for several specialties. Method This retrospective, observational study used national data from 2003 and standard financial techniques to calculate the net present value-the current value of an expected stream of cash flows at a particular rate of interest-of the educational investments of medical students in ten 30-year career paths: either military or civilian careers in internal medicine, psychiatry, gastroenterology, general surgery, or orthopedics. Results At a 5% discount rate, in the civilian world, the lowest return on an educational investment accrued to psychiatrists ($1.136 million) and the highest to orthopedists ($2.489 million), a range of $1.354 million. In the military, the lowest returns accrued to internists ($1.377 million) and the highest to orthopedists ($1.604 million); however, the range was only $0.227 million, one-sixth that found in the civilian sector. The authors also found that most military physicians do not remain in the military for their full careers. Conclusions Choosing a military career substantially decreases the net present value of an educational investment for interventionalists, but it does so only modestly for primary care physicians. Further, a military career path markedly diminishes specialty-specific variation in the net present values of educational investment. Adopting a military structure for engaging medical students might help reverse the current trend of declining interest in primary care.

The resulting FeO(x)-carbon nanofoams are characterized as device-ready electrode structures for aqueous electrochemical capacitors and they demonstrate a 3-to-7 fold increase in charge-storage capacity relative to the native carbon nanofoam when cycled in a mild aqueous electrolyte (2.5 M Li(2)SO(4)), yielding mass-, volume-, and footprint-normalized capacitances of 84 F g(-1), 121 F cm(-3), and 0.85 F cm(-2), respectively, even at modest FeO(x) loadings (27 wt %). The additional charge-storage capacity arises from faradaic pseudocapacitance of the FeO(x) coating, delivering specific capacitance >300 F g(-1) normalized to the content of FeO(x) as FeOOH, as verified by electrochemical measurements and in situ X-ray absorption spectroscopy. The additional capacitance is electrochemically addressable within tens of seconds, a time scale of relevance for high-rate electrochemical charge storage. We also demonstrate that the addition of borate to buffer the Li(2)SO(4) electrolyte effectively suppresses the electrochemical dissolution of the FeO(x) coating, resulting in <20% capacitance fade over 1000 consecutive cycles.

STUDY DESIGN: A retrospective cohort study of pregnant women referred for colposcopy from 2004-2007 at four academic centers. RESULTS: One thousand seventy-nine patients were identified. Colposcopic impression by cervical cytology is detailed later in the text. Of patients who underwent biopsy, results correlated with or were less severe than colposcopic impression in 83% with CIN 1 and 56% with CIN 2/3. Fifty-seven percent had follow-up postpartum, with 61% reverting normal. Resolution of cervical dysplasia was inversely associated with smoking (P = .002). No progression to cancer occurred during pregnancy. CONCLUSION: Colposcopic impression in pregnancy correlated with cervical biopsy results and postpartum colposcopic findings when performed by expert colposcopists. A high proportion of cervical dysplasia regressed postpartum. Cervical biopsies in pregnancy may not be necessary unless invasive cancer is suspected.

We analyzed how ease of geographic access to emergency departments (EDs), defined as driving time to the closest ED, changed between 2001 and 2005, and whether access deterioration was more likely to occur in vulnerable communities. Methods. We classified communities on the basis of American Hospital Association and Census data into 3 categories according to driving time to the nearest ED: no increase, less than a 10-minute increase, and a 10-minute or more increase. We estimated a multinomial logit model to examine the relative risk ratio (RRR) of various community characteristics. Results. More than 95% of communities experienced no ED access deterioration. However, 11.4 million people experienced increased driving time to their nearest ED. Low-income communities had a higher risk of facing deteriorating access compared with high-income communities (urban: RRR=3.67; P<.01; rural: RRR= 1.75; P<.10), and communities with higher shares of Hispanics also had higher risks of facing declines (urban: RRR=3.41; P<.10; rural: RRR=2.67; P<.01). Conclusions. Deteriorating access to EDs is more likely to occur in communities with economic hardship and high shares of Hispanic populations. The uneven access to critical services warrants increased attention from policy-making bodies.

The usual injury mechanism is during eccentric shortening of the pectoralis major under heavy load, such as when performing a bench press exercise. The ability to detect and treat a pectoralis major rupture is important for both the clinician and the patient and is aided with knowledge of the anatomy, the clinical findings, and results of nonoperative and operative care. It is important to understand the physical demands and desires of the patient as well as to understand the outcomes of both nonoperative and operative care to make an informed decision regarding optimal treatment. This article highlights the importance of the clinical examination in identifying the injury, examines various surgical techniques to repair the rupture, and reports on potential complication and reinjury rates.

We characterized the magnitude of the outbreak through disease surveillance and serosurveys, and investigated contributing factors to enhance strategies for forecasting to prevent or minimize the impact of future outbreaks. Of 700 suspected cases, 392 met probable or confirmed case definitions; demographic data were available for 340 (87%), including 90 (26.4%) deaths. Male cases were more likely to die than females, Case Fatality Rate Ratio 1.8 (95% Confidence Interval [CI] 1.3-3.8). Serosurveys suggested an attack rate up to 13% of residents in heavily affected areas. Genetic sequencing showed high homology among viruses from this and earlier RVF outbreaks. Case areas were more likely than non-case areas to have soil types that retain surface moisture. The outbreak had a devastatingly high case-fatality rate for hospitalized patients. However, there were up to 180,000 infected mildly ill or asymptomatic people within highly affected areas. Soil type data may add specificity to climate-based forecasting models for RVF.

Entomologic surveillance was performed in four districts to determine the epidemic/epizootic vectors of RVF virus (RVFV). Approximately 297,000 mosquitoes were collected, 164,626 identified to species, 72,058 sorted into 3,003 pools and tested for RVFV by reverse transcription-polymerase chain reaction. Seventy-seven pools representing 10 species tested positive for RVFV, including Aedes mcintoshi/circumluteolus (26 pools), Aedes ochraceus (23 pools), Mansonia uniformis (15 pools); Culex poicilipes, Culex bitaeniorhynchus (3 pools each); Anopheles squamosus, Mansonia africana (2 pools each); Culex quinquefasciatus, Culex univittatus, Aedes pembaensis (1 pool each). Positive Ae. pembaensis, Cx. univittatus, and Cx. bitaeniorhynchus was a first time observation. Species composition, densities, and infection varied among districts supporting hypothesis that different mosquito species serve as epizootic/epidemic vectors of RVFV in diverse ecologies, creating a complex epidemiologic pattern in East Africa.

TI Pathologic Studies on Suspect Animal and Human Cases of Rift Valley Fever from an Outbreak in Eastern Africa, 2006-2007 SO AMERICAN JOURNAL OF TROPICAL MEDICINE AND HYGIENE LA English DT Article ID HEMORRHAGIC-FEVER; NEWBORN LAMBS; LASSA FEVER; VIRUS; PATHOGENESIS; TISSUES; LESIONS; DIAGNOSIS; ANTIGEN; DISEASE AB Rift Valley fever (RVF) is an important viral zoonotic disease in Africa with periodic outbreaks associated with severe disease, death, and economic hardship. During the 2006-2007 outbreaks in Eastern Africa, postmortem and necropsy tissue samples from 14 animals and 20 humans clinically suspected of RVF were studied with histopathologic evaluation and immunohistochemical (IHC) assays. Six animal and 11 human samples had IHC evidence of Rift Valley fever virus (RVFV) antigens. We found that extensive hepatocellular necrosis without prominent inflammatory cell infiltrates is the most distinctive histopathologic change in liver tissues infected with RVFV. Pathologic studies on postmortem tissue samples can help establish the diagnosis of RVF, differentiating from endemic diseases with clinical manifestations similar to RVF, such as malaria, leptospirosis, or yellow fever.

In cardiac arrest, the smooth muscle of the lower esophageal sphincter relaxes in a time-dependent and irreversible manner. If relaxation also occurs in the muscular posterior tracheal wall, it could predispose tracheal invagination or collapse with negative pressure, potentially yielding false-negative (tracheal ET, EDD indicates esophagus) results. We compared 3 different EDDs in their ability to correctly discriminate tracheal and esophageal intubation. METHODS: ETTs were placed into the trachea and esophagus of 5 domestic swine, and bronchoscopy was used to visualize the trachea while 3 EDDs were tested. Tracheal wall activity was observed before and after induced cardiac arrest. Tracheal ETTs were aspirated with increasing negative force and pressures at initial wall movement and >50% tracheal lumen obliteration were recorded. Measurements were repeated at 4, 8, and 12 minutes postarrest and pressures at tracheal wall collapse pre- and postarrest were determined. EDDs were also tested on esophageal ETTs prearrest and at 6 and 10 minutes postarrest. RESULTS: In a closed system, each EDD generated more than -100 cm H(2)O pressure. Average prearrest pressure at tracheal collapse was -112 cm H(2)O. Average postarrest collapse pressures were -68, -66, and -54 cm H(2)O at 4, 8, and 12 minutes postarrest. One EDD consistently gave equivocal results; the remaining 2 gave accurate results in all subjects. Most observed movement was insufficient to cause device failure although tracheal wall movement was noted in all postarrest EDD trials. Esophageal intubation was correctly determined at all times pre- and postarrest. CONCLUSION: These findings describe a mechanism for false-negative results from decreased posterior tracheal wall tone during cardiac arrest. Further studies are required to elucidate factors contributing to its occurrence and impact on EDD use.

TI Study of Composite Interface Fracture and Crack Growth Monitoring Using Carbon Nanotubes SO APPLIED COMPOSITE MATERIALS LA English DT Article DE Composites interface; Fracture strength; Carbon nanotubes; Crack monitoring ID STRAIN; REINFORCEMENT; STRENGTH AB Interface fracture of woven fabric composite layers was studied using Mode II fracture testing. Both carbon fiber and E-glass fiber composites were used with a vinyl ester resin. First, the single-step cured (i.e., co-cured) composite interface strength was compared to that of the two-step cured interface as used in the scarf joint technique. The results showed that the two-step cured interface was as strong as the co-cured interface. Carbon nanotubes were then applied to the composite interface using two-step curing, and then followed by Mode II fracture testing. The results indicated a significant improvement of the interface fracture toughness due to the dispersed carbon nanotube layer for both carbon fiber and E-glass fiber composites. The carbon nanotube layer was then evaluated as a means to monitor crack growth along the interface. Because carbon nanotubes have very high electrical conductivity, the electrical resistance was measured through the interface as a crack grew, thus disrupting the carbon nanotube network and increasing the resistance. The results showed a linear relationship between crack length and interface resistance for the carbon fiber composites, and allowed initial detection of failure in the E-glass fiber composites. This study demonstrated that the application of carbon nanotubes along a critical composite interface not only improves fracture properties but can also be used to detect and monitor interfacial damage.

An Er : YAG laser (2937 nm, 350 mu s) is used as a light source and the effect of the energy density supplied by the laser on the morphology of the deposited films is investigated. It is found that the appearance of undesirable non-uniform morphological features arises from either poor solubility of the guest molecules or insufficient energy density provided by the laser to vaporize the entire ejected volume. In addition, the surface roughness of two guest-host systems is found to depend linearly on the polymer concentration. These results allow us to better understand earlier work in the field and to establish a framework by which MAPLE films may be improved.

From the spectroscopic and imaging information, we determined the fundamental geometry of the outflow and inner disk, via two modeling programs used to recreate the morphology of these regions imaged with HST. We also determined that the bicone of ionizing radiation from the active galactic nucleus intersects with the inner disk, illuminating a section of the disk including inner segments of spiral arms, fully seen through structure mapping, which appear to be outflowing and expanding. In addition, we see high velocities at projected distances of >= 2 '' (similar to 700 pc) from the nucleus, which could be due to rotation or in situ acceleration of gas off the spiral arms. We find that the true half-opening angle of the ionizing bicone (53 degrees) is much larger than the apparent half-opening angle (34 degrees) due to the above geometry, which may apply to a number of other Seyferts as well.

TI BRORFELDE SCHMIDT CCD CATALOG SO ASTRONOMICAL JOURNAL LA English DT Article DE astrometry; catalogs; methods: data analysis ID DIGITAL SKY SURVEY; SURVEY 2MASS; UCAC3 AB The Brorfelde Schmidt CCD Catalog (BSCC) contains about 13.7 million stars, north of +49 degrees decl. with precise positions and V, R photometry. The catalog has been constructed from the reductions of 18,667 CCD frames observed with the Brorfelde Schmidt Telescope between 2000 and 2007. The Tycho-2 catalog was used for astrometric and photometric reference stars. Errors of individual positions are about 20-200 mas for stars in the R = 10-18 mag range. External comparisons with the Two Micron All-Sky Survey (2MASS) and Sloan Digital Sky Survey reveal possible small systematic errors in the BSCC of up to about 30 mas.

TI DISCOVERY OF A GeV BLAZAR SHINING THROUGH THE GALACTIC PLANE SO ASTROPHYSICAL JOURNAL LETTERS LA English DT Article DE galaxies: active ID LARGE-AREA TELESCOPE; VARIABLE RADIO-SOURCES; NORTHERN MILKY-WAY; GAMMA-RAY EMISSION; GHZ SOURCES; SKY SURVEY; CATALOG; SPECTRA; PATROL AB The Fermi Large Area Telescope (LAT) discovered a new gamma-ray source near the Galactic plane, Fermi J0109+6134, when it flared brightly in 2010 February. The low Galactic latitude (b = -1 degrees.2) indicated that the source could be located within the Galaxy, which motivated rapid multi-wavelength follow-up including radio, optical, and X-ray observations. We report the results of analyzing all 19 months of LAT data for the source, and of X-ray observations with both Swift and the Chandra X-ray Observatory. We determined the source redshift, z = 0.783, using a Keck Low-Resolution Imaging Spectrometer observation. Finally, we compiled a broadband spectral energy distribution (SED) from both historical and new observations contemporaneous with the 2010 February flare. The redshift, SED, optical line width, X-ray absorption, and multi-band variability indicate that this new GeV source is a blazar seen through the Galactic plane. Because several of the optical emission lines have equivalent width > 5 angstrom, this blazar belongs in the flat-spectrum radio quasar category.

TI Mammographic density does not differ between unaffected BRCA1/2 mutation carriers and women at low-to-average risk of breast cancer SO BREAST CANCER RESEARCH AND TREATMENT LA English DT Article DE Mammographic density; Breast cancer risk; Breast cancer screening; Gene, BRCA1; Gene, BRCA2; Genetic predisposition to disease ID INCREASED GENETIC RISK; PARENCHYMAL PATTERNS; FAMILY-HISTORY; COMPUTERIZED ANALYSIS; FEATURES; CARCINOMA; TISSUE; AGE AB Elevated mammographic density (MD) is one of the strongest risk factors for sporadic breast cancer. Epidemiologic evidence suggests that MD is, in part, genetically determined; however, the relationship between MD and BRCA1/2 mutation status is equivocal. We compared MD in unaffected BRCA1/2 mutation carriers enrolled in the U.S. National Cancer Institute's Clinical Genetics Branch's Breast Imaging Study (n = 143) with women at low-to-average breast cancer risk enrolled in the same study (n = 29) or the NCI/National Naval Medical Center's Susceptibility to Breast Cancer Study (n = 90). The latter were BRCA mutation-negative members of mutation-positive families or women with no prior breast cancer, a Pedigree Assessment Tool score < 8 (i.e., low risk of a hereditary breast cancer syndrome) and a Gail score < 1.67. A single experienced mammographer measured MD using a computer-assisted thresholding method. We collected standard breast cancer risk factor information in both studies. Unadjusted mean percent MD was higher in women with BRCA1/2 mutations compared with women at low-to-average breast cancer risk (37.3% vs. 33.4%; P = 0.04), but these differences disappeared after adjusting for age and body mass index (34.9% vs. 36.3%; P = 0.43). We explored age at menarche, nulliparity, age at first birth, menopausal status, number of breast biopsies, and exposure to exogenous hormonal agents as potential confounders of the MD and BRCA1/2 association. Taking these factors into account did not significantly alter the results of the age/body mass index-adjusted analysis. Our results do not provide support for an independent effect of BRCA1/2 mutation status on mammographic density.

TI Extinction of premixed methane/air flames in microgravity by diluents: Effects of radiation and Lewis number SO COMBUSTION AND FLAME LA English DT Article DE Extinction; Microgravity; Inert gases; Lewis number; Radiation and reabsorption; Chemical suppression ID COUNTERFLOW DIFFUSION FLAMES; FLAMMABILITY-LIMIT; HEAT-LOSS; ASYMPTOTIC ANALYSIS; H-2-AIR FLAMES; NOX FORMATION; CO2 ADDITION; INERT-GASES; CUP-BURNER; LAMINAR AB Laminar burning velocities and flammability limits of premixed methane/air flames in the presence of various diluents were investigated by combined use of experiments and numerical simulations. The experiments used a 1-m free-fall spherical combustion chamber to eliminate the effect of buoyancy, enabling accurate measurements of near-limit burning velocities and flammability limits. Burning velocities were measured for CH(4)/air flames with varying concentrations of He, Ar, N(2) and CO(2) at NTP. The limiting concentration of each diluent was measured by systematically varying the composition and ignition energy and finding the limiting condition through successive experiment trials. The corresponding freely-propagating, planar 1-D flames were simulated using PREMIX. The transient spherically-expanding flames were simulated using the 1-D Spherical Flame & Reactor Module of COSILAB considering detailed radiation models. The results show that helium exhibits more complex limit behavior than the other diluents due to the large Lewis number of helium mixtures. The near-limit helium-diluted flames require much higher ignition energy than the other flames. In addition, for the spherically expanding helium-diluted flames studied here (Le > 1), stretch suppresses flame propagation and may cause flame extinction. For the CO(2)-diluted flames, the flame speed predicted by the optically-thick model based on the Discrete Transfer Method (DTW) and a modified wide band model has better agreement with measurements in the near-limit region. A significant amount of heat is absorbed by the dilution gas CO(2), resulting in elevation of temperature of the ambient gases. The optically-thick model, however, still overpredicts flame speed, indicating a more sophisticated radiation property model may be needed. Finally, the chemical effect of CO(2) on flame suppression was quantified by a numerical analysis. The results show that the chemical effect of CO(2) is more important than the other diluents due to its active participation in the reaction CO(2) + H = CO + OH, which competes for H radicals with the chain-branching reactions and thus reduces flame speed.

Rather than present some pedantic general survey of the history of organized crime in modern Turkey, this essay attempts to address two broader critical points of departure. First, how did Anatolia's journey from imperial to republican rule impact, and how was it impacted by, criminal gangs? Second, how do we situate the experience of modern gangs in Turkey in a global context? In attempting to answer these questions, this paper looks at the development of criminal syndicates among Laz migrants in the greater Istanbul area during the first half of the twentieth century. The case of the Laz shows particularly how war, migration, imperial politics, urbanisation and the rise of the international drug trade shaped the parallel development of organised crime and the nascent Turkish Republic.

Viruses are introduced as protein cages, scaffolds, and templates for the production of biohybrid nanostructured materials where organic and inorganic molecules are incorporated in a precise and a controlled fashion. Genetic engineering enables the insertion or replacement of selected amino acids on virus capsids for uses from bioconjugation to crystal growth. The variety of nanomaterials generated in rod-like and spherical viruses is highlighted for tobacco mosaic virus (TMV), M13 bacteriophage, cowpea chlorotic mottle virus (CCMV), and cowpea mosaic virus (CPMV).

TI Persian Gulf response to a wintertime shamal wind event SO DEEP-SEA RESEARCH PART I-OCEANOGRAPHIC RESEARCH PAPERS LA English DT Article DE Persian Gulf; Shamal wind; Heat flux; Circulation; Numerical model ID VERTICAL DIFFUSIVITIES; OCEAN TURBULENCE; RESIDUAL FLOW; ARABIAN GULF; HEAT; HORMUZ; MOMENTUM; STRAIT; MODEL AB The results from a similar to 1 km resolution HYbrid Coordinate Ocean Model (HYCOM), forced by 1/2 degrees Navy Operational Global Atmospheric Prediction System (NOGAPS) atmospheric data, were used in order to study the dynamic response of the Persian Gulf to wintertime shamal forcing. Shamal winds are strong northwesterly winds that occur in the Persian Gulf area behind southeast moving cold fronts. The period from 20 November to 5 December 2004 included a well defined shamal event that lasted 4-5 days. In addition to strong winds (16 m s(-1)) the winter shamal also brought cold dry air (T(a) = 20 degrees C, q(a) = 10 g kg(-1)) which led to a net heat loss in excess of 1000 W m(-2) by increasing the latent heat flux. This resulted in SST cooling of up to 10 degrees C most notably in the northern and shallower shelf regions. A sensitivity experiment with a constant specific humidity of q(a) = 15 g kg(-1) confirmed that about 38% of net heat loss was due to the air-sea humidity differences. The time integral of SST cooling closely followed the air-sea heat loss, indicating an approximate one-dimensional vertical heat balance. It was found that the shamal induced convective vertical mixing provided a direct mechanism for the erosion of stratification and deepening of the mixed layer by 30 m. The strong wind not only strengthened the circulation in the entire Persian Gulf but also established a northwestward flowing Iranian Coastal Current (ICC, 25-30 cm s(-1)) from the Strait of Hormuz to about 52 degrees E, where it veered offshore. The strongest negative sea level of 25-40 cm was generated in the northernmost portion of the Gulf while the wind setup against the coast of the United Arab Emirates established a positive sea level of 15-30 cm. The transport through the Strait of Hormuz at 56.2 degrees E indicated an enhanced outflow of 0.25 Sv (Sv equivalent to 10(6) m(3) s(-1)) during 24 November followed by an equivalent inflow on the next day.

CA Millennium Cohort Study Team TI Risk of Diabetes in US Military Service Members in Relation to Combat Deployment and Mental Health SO DIABETES CARE LA English DT Article ID POSTTRAUMATIC-STRESS-DISORDER; INSULIN-RESISTANCE; PRIMARY-CARE; DEPRESSION; PERFORMANCE; CHECKLIST; VETERANS; MELLITUS; ADULTS; SPAN AB OBJECTIVE Few prospective data exist on the risk of diabetes in individuals serving in the U.S. military. The objectives of this study were to determine whether military deployment, combat exposures, and mental health conditions were related to the risk of newly reported diabetes over 3 years. RESEARCH DESIGN AND METHODS Data were from Millennium Cohort Study participants who completed baseline (July 2001-June 2003) and follow-up (June 2004-February 2006) questionnaires (follow-up response rate = 71.4%). After exclusion criteria were applied, adjusted analyses included 44,754 participants (median age 36 years, range 18-68 years). Survey instruments collected demographics, height, weight, lifestyle, military service, clinician-diagnosed diabetes, and other physical and mental health conditions. Deployment was defined by U.S. Department of Defense databases, and combat exposure was assessed by self-report at follow-up. Odds of newly reported diabetes were estimated using logistic regression analysis. RESULTS Occurrence of diabetes during follow-up was 3 per 1,000 person-years. Individuals reporting diabetes at follow-up were significantly older, had greater baseline BMI, and were less likely to be Caucasian. After adjustment for age, sex, BMI, education, race/ethnicity, military service characteristics, and mental health conditions, only baseline posttraumatic stress disorder (PTSD) was significantly associated with risk of diabetes (odds ratio 2.07 [95% Cl 1.31-3.29]). Deployments since September 2001 were not significantly related to higher diabetes risk, with or without combat exposure. CONCLUSIONS In this military cohort, PTSD symptoms at baseline but not other mental health symptoms or military deployment experience were significantly associated with future risk of self-reported diabetes.

TI Simulated and observed circulation in the Indonesian Seas: 1/12 degrees global HYCOM and the INSTANT observations SO DYNAMICS OF ATMOSPHERES AND OCEANS LA English DT Article DE Indonesian Throughflow; Global HYCOM; INSTANT; Inter-ocean exchange; Ocean modeling ID SOUTH CHINA SEA; OCEAN MODEL HYCOM; INDIAN-OCEAN; THERMOHALINE CIRCULATION; VERTICAL DIFFUSIVITIES; GENERAL-CIRCULATION; WORLD OCEAN; PART I; THROUGHFLOW; DYNAMICS AB A 1/12 degrees global version of the HYbrid Coordinate Ocean Model (HYCOM) using 3-hourly atmospheric forcing is analyzed and directly compared against observations from the International Nusantara STratification ANd Transport (INSTANT) program that provides the first long-term (2004-2006) comprehensive view of the Indonesian Throughflow (ITF) inflow/outflow and establishes an important benchmark for inter-basin exchange, including the net throughflow transport. The simulated total ITF transport (-13.4 Sv) is similar to the observational estimate (similar to 15.0 Sy) and correctly distributed among the three outflow passages (Lombok Strait. Ombai Strait and Timor Passage). Makassar Strait carries similar to 75% of the observed total ITF inflow and while the temporal variability of the simulated transport has high correlation with the observations, the simulated mean volume transport is similar to 37% too low. This points to an incorrect partitioning between the western and eastern inflow routes in the model and is the largest shortcoming of this simulation. HYCOM simulates the very deep (>1250m) overflow at Lifamatola Passage (-2.0 Sv simulated vs. -2.5 Sv observed) and indicates overflow contributions originating from the North (South) Equatorial Current in boreal winter-spring (summer-autumn). A new finding of INSTANT is the mean eastward flow from the Indian Ocean toward the interior Indonesian Seas on the north side of Ombai Strait. This flow is not robustly simulated at 1/12 degrees resolution, but is found in a 1/25 degrees version of global HYCOM using climatological forcing, indicating the importance of horizontal resolution. However, the 1/25 degrees model also indicates that the mean eastward flow retroflects, turning back into the main southwestward Ombai Strait outflow, and in the mean does not enter the interior seas to become part of the water mass transformation process. The 1/12 degrees global HYCOM is also used to fill in the gaps not measured as part of the INSTANT observational network. It indicates the wide and shallow Java and Arafura Seas carry -0.8 Sv of inflow and that the three major outflow passages capture nearly all the total Pacific to Indian Ocean throughflow.

TI Isotopic anomalies in organic nanoglobules from Comet 81P/Wild 2: Comparison to Murchison nanoglobules and isotopic anomalies induced in terrestrial organics by electron irradiation SO GEOCHIMICA ET COSMOCHIMICA ACTA LA English DT Article ID X-RAY-ABSORPTION; MOLECULAR-CLOUD MATERIAL; INNER-SHELL EXCITATION; DEUTERIUM FRACTIONATION; INTERPLANETARY DUST; AROMATIC-HYDROCARBONS; PRIMITIVE METEORITES; INTERSTELLAR CLOUDS; PRESOLAR GRAPHITE; CORE EXCITATION AB Nanoglobules are a form of organic matter found in interplanetary dust particles and primitive meteorites and are commonly associated with N-15 and D isotopic anomalies that are suggestive of interstellar processes. We report the discovery of two isotopically-anomalous organic globules from the Stardust collection of particles from Comet 81P/Wild 2 and compare them with nanoglobules from the Murchison CM2 meteorite. One globule from Stardust Cometary Track 80 contains highly aromatic organic matter and a large N-15 anomaly (delta N-15 = 1120 parts per thousand). Associated, non-globular, organic matter from this track is less enriched in N-15 and contains a mixture of aromatic and oxidized carbon similar to bulk insoluble organic material (IOM) from primitive meteorites. The second globule, from Cometary Track 2, contains non-aromatic organic matter with abundant nitrile (-C N) and carboxyl (-COOH) functional groups. It is significantly enriched in D (delta D = 1000 parts per thousand) but has a terrestrial N-15/N-14 ratio. Experiments indicate that similar D enrichments, unaccompanied by N-15 fractionation, can be reproduced in the laboratory by electron irradiation of epoxy or cyanoacrylate. Thus, a terrestrial origin for this globule cannot be ruled out, and, conversely, exposure to high-energy electron irradiation in space may be an important factor in producing D anomalies in organic materials. For comparison, we report two Murchison globules: one with a large N-15 enrichment and highly aromatic chemistry analogous to the Track 80 globule and the other only moderately enriched in N-15 with IOM-like chemistry. The observation of organic globules in Comet 81P/Wild 2 indicates that comets likely sampled the same reservoirs of organic matter as did the chondrite parent bodies. The observed isotopic anomalies in the globules are most likely preserved signatures of low temperature (<10 K) chemistry in the interstellar medium or perhaps the outer regions of the solar nebula. In other extraterrestrial samples, D isotopic anomalies, but not those of N-15, may be explained in part by exposure to ionizing electron radiation. (C) 2010 Elsevier Ltd. All rights reserved.

The wall-plug efficiency for the FEL oscillator and amplifier (uniform and tapered wiggler) is strongly dependent on the energy recovery process. A theoretical model for electron beam dynamics in the energy recovery linac is derived and applied to the acceleration and deceleration of nano-Coulomb electron bunches for a tapered FEL amplifier. For the tapered amplifier, the spent electron beam exiting the wiggler consists of trapped and untrapped electrons. Decelerating these two populations using different phases of the radio-frequency wave in the recovery process enhances wall-plug efficiency. For the parameters considered here, the wall-plug efficiency for the tapered amplifier can be similar to 10% using this approach.

FMCW is desirable for through-slab applications because of the signal gain resulting from pulse compression of long transmit pulses (1.926-4.069 GHz chirp in 10 ms). The difficulty in utilizing FMCW radar for this application is that the air-slab boundary dominates the scattered return from the target scene and limits the upper bound of the receiver dynamic range, reducing sensitivity for targets behind the slab. A method of range-gating out the air-slab boundary by significant band-limiting of the IF stages facilitates imaging of low radar cross section (RCS) targets behind the slab. This sensor is combined with a 1D linear rail and utilized as a rail synthetic aperture radar (SAR) imaging system. A 2D model of a slab and cylinder shows that image blurring due to the slab is negligible when the SAR is located at a stand-off range of 6 m or greater, and thus, the two-way attenuation due to wave propagation through the slab is the greatest challenge at stand-off ranges when the air-slab boundary is range-gated out of the scattered return. Measurements agree with the model, and also show that this radar is capable of imaging target scenes of cylinders and rods 15.24 cm in height and 0.95 cm in diameter behind a 10 cm thick lossy dielectric slab. Further, this system is capable of imaging free-space target scenes with transmit power as low as 5 pW, providing capability for RCS measurement.

A computational model resolution of 1 mm has been used for most of the human body model, including regions proximal to the electrode contact points, while a progressively coarser resolution up to 5 mm is utilized, according to an expanding grid scheme for body regions distant from the source, such as the lower extremities. Using quasi-static assumptions, discrete Fourier transforms have been used to average the electric field values at the desired frequencies for times much shorter than their time periods. The field values induced in the human body were then obtained as ratios with respect to the source, which can be scaled depending on the magnitude. This study suggests that the ADI-FDTD method can be used for the solution of low-frequency large-scale bioelectromagnetic problems. It is shown that, when used with quasi-static assumptions, Fourier series decomposition, and expanding grid, the D-H ADI-FDTD can be an effective computational bioelectromagnetics tool.

By holding the input to the string of inverters at high voltage (1.8 V) during exposure to ionizing radiation, an asymmetry in the threshold voltages of the n-channel transistors is induced, i.e., the inputs to the inverters alternate between high and low voltage, which results in every odd-numbered n-channel transistor experiencing more Total Ionizing Dose (TID) degradation than the even-numbered n-channel transistors. The asymmetry manifests itself as an additional broadening of laser-light induced transients when the input to the string of inverters is set to low voltage and a contraction of the transients when the input is set to high voltage. Exposure of the inverter string to heavy ions with a fixed input voltage resulted in a contraction of the transients, regardless of whether the input was at high or low voltage, behavior that is consistent with the results from pulsed laser testing.

TI Large SET Duration Broadening in a Fully-Depleted SOI Technology-Mitigation With Body Contacts SO IEEE TRANSACTIONS ON NUCLEAR SCIENCE LA English DT Article; Proceedings Paper CT 10th European Conference on Radiation and Its Effects on Components and Systems (RADECS - 09) CY SEP 14-18, 2009 CL Bruges, BELGIUM DE Body contacts; floating body effects; propagation induced pulse broadening; single event transient ID SINGLE-EVENT TRANSIENTS; HEAVY-ION IRRADIATION; PULSED-LASER; DIGITAL CMOS; PROPAGATION; TRANSISTORS; MOSFETS; CIRCUITS; INSIGHTS; GENERATION AB Significant floating body effects were measured in 0.2 m fully-depleted SOI resulting in large amounts of single event transient (SET) broadening, i.e., SET duration stretching. The transient response of single transistors and the propagation of single-event transients (SET) in chains of logic gate (inverters and NOR gates) were investigated by using either heavy ion irradiation or focused laser pulses. Single transistors displayed a particularly slow recovery after an ion strike (>100 ns). In logic chains, large amounts of SET duration broadening, up to 30 ps/gate, were measured when the unattenuated rail-to-rail SET propagates to the output of the chain. These floating body effects occur mainly at low frequency. They are induced by the accumulation of majority carriers in the body region which contribute to reduce the threshold voltage of OFF-state transistors. This is a slow phenomenon which takes up to several tenths of a second to build-up. It is demonstrated that floating body effects are reduced when designed with body contacts or when the chain operates at high frequency.

TI Estimation of Heavy-Ion LET Thresholds in Advanced SOI IC Technologies From Two-Photon Absorption Laser Measurements SO IEEE TRANSACTIONS ON NUCLEAR SCIENCE LA English DT Article; Proceedings Paper CT 10th European Conference on Radiation and Its Effects on Components and Systems (RADECS - 09) CY SEP 14-18, 2009 CL Bruges, BELGIUM DE Hardness assurance; heavy-ion testing; laser testing; single-event upset; threshold LET; two-photon absorption ID SINGLE-EVENT-UPSET; TRANSIENT-RESPONSE; PULSED-LASER; ENERGY; SRAM; TRANSISTORS; LATCHUP; IMPACT; CELLS AB The laser energy thresholds for SEU for SOI 1-Mbit SRAMs built in Sandia's 0.35-m SOI technology were measured using carrier generation by two-photon absorption. The laser measurements were correlated to heavy-ion threshold LET measurements to determine an empirical relationship between laser energy threshold and heavy-ion threshold LET. This empirical relationship was used to estimate the threshold LETs for other circuits built in Sandia's 0.35-m SOI technology and SRAMs built in IBM's 45 and 65-nm SOI technologies. For an ASIC built in Sandia's 0.35-m SOI technology the estimated threshold from laser measurements was close to the measured heavy-ion threshold LET. However, for a dual-port SRAM also built in Sandia's 0.35-m SOI technology and for the 45- and 65-nm IBM SOI SRAMs, the threshold LETs estimated from laser measurements did not correlate to the measured heavy-ion threshold LETs. For the IBM SRAMs, the likely cause of the discrepancy between the threshold LETs estimated from laser measurements and the threshold LETs measured by heavy-ion testing is due to the laser pulse simultaneously injecting charge into multiple transistors within a memory cell and/or in adjacent memory cells. This is due to the relatively large size of the laser spot size compared to the size of the SEU sensitive volume of the IBM SOI devices. The hardness assurance implications of these results are discussed.

Spatial correlation between excess channel carriers and the horizontal field is shown to be the key factor. Hole accumulation in the AlSb buffer layer increases the electron concentration in the two-dimensional electron gas, increasing the collected charge. Potential drop across access regions reduces charge collection towards zero gate bias. A secondary but perceptible dependence on high field electron mobility is demonstrated.

Following 0.6 and 1 MeV electron irradiation, the measured DLTS spectra matched that of the literature. After 5 MeV electron irradiation, however, a new DLTS peak was observed. The new peak is located on the low temperature side of the common E3 peak. This new electron-induced DLTS peak is assigned to be the same peak produced by proton irradiation and commonly labeled PR4 ''. Further analysis of the DLTS data indicate that the PR4 '' peak is independent of the displacement damage dose deposited but is dependent on the primary recoil energy.

It represents the given function as an edge-valued multiple-valued decision diagram (EVMDD), and shows a systematic design method based on the EVMDD. To achieve a design, we characterize a numeric function f by the values of I and p for which f is an l-restricted Mp-monotone increasing function. Here, l is a measure of sub-functions of f and p is a measure of the rate at which f increases with an increase in the dependent variable. For the special case of an EVMDD, the EVBDD, we show an upper bound on the number of nodes needed to realize an l-restricted Mp-monotone increasing function. Experimental results show that all of the two-variable numeric functions considered in this paper can be converted into an l-restricted Mp-monotone increasing function with p = 1 or 3. Thus, they can be compactly realized by EVBDDs. Since EVMDDs have shorter paths and smaller memory size than EVBDDs, EVMDDs can produce fast and compact NFGs.

TI Estimating surface water flow speeds using time-frequency methods SO IET SIGNAL PROCESSING LA English DT Article ID MOVING TARGETS AB Synthetic aperture radar (SAR) image formation implicitly assumes that the backscattered returns arise from stationary isotropic targets. When objects move during the SAR integration time, signal anomalies appear that distort, displace and smear moving targets in the image. Although these anomalies degrade the image, they provide the information that allows analysis of the underlying target motion. Joint time-frequency analysis (JTFA) exploits these signal anomalies to estimate the motion of typical point targets. However, the weak, transient returns from water surface scatterers complicate standard JTFA estimates of water surface speeds. A time-frequency representation is applied based on the Capon's spectral estimation technique that allows joint analysis of multiple azimuth lines, thereby increasing the signal-to-clutter ratio of weak scatterers. The authors compare the time-frequency estimate, employing single-phase-centre SAR data, to along-track interferometric SAR estimates of the same flow and show that both the methods produce comparable results. The authors derive the JTFA equations and estimate water surface speed for data collected at a specific imaging geometry. This study highlights the feasibility of using a single-phase-centre SAR system to determine the motion of slow moving distributed targets representative of water flow. C1 [Kersten, P. R.; Jansen, R.

TI Transition to turbulence in the separated shear layers of yawed circular cylinders SO INTERNATIONAL JOURNAL OF HEAT AND FLUID FLOW LA English DT Article DE Transition to turbulence; Yawed circular cylinders; Separated shear layers; Large-eddy simulation ID LARGE-EDDY SIMULATION; REYNOLDS-NUMBERS; WAKE; INSTABILITY AB Spatial and temporal resolution of transition to turbulence inside the free-shear layers of two yawed circular cylinders is the subject of the present investigation. These physics were resolved using the large-eddy simulation (LES) methodology. An O-type grid was implemented such that the spatial scales of the LES computation fully resolved the energy range physics of the shear layers at Reynolds number Re(D) = 8000 based on the cylinder diameter. The two test cases modeled the cylinder span skewed at angles 45 degrees and 60 degrees from the horizontal axis. Observations revealed the same transition process as the normal cross-flow state. Soon after separation, Tollmien-Schlichting disturbances were predicted that evolved into Kelvin-Helmholtz (K-H) eddies before absorption by the large-scale Karman-type vortices. These eddies defaulted to a spanwise wavy pattern similar to a normal cross-flow due to their three-dimensional instability. No mixed modes were found between the K-H (Bloor) and Strouhal frequencies. The effect of yaw angle shortened the transition process. As a result, peak turbulence levels inside the wake formation zone approach the downstream cylinder periphery. In addition, the dimensionless frequencies of the K-H eddies lie above the normal cross-flow relationship as formulated by Bloor (1964). Disparity between the yawed and normal cross-flow states was further emphasized by the shear-layer transition characteristics. Although each property displayed the expected exponential growth during transition to turbulence, their dimensionless form was miss-aligned with those of the normal cross-flow case. Based on the present evidence, additional simulations (and/or experimental measurements) are necessary to form conclusive arguments regarding the expected behavior of the transition characteristics within the free-shear layers of yawed circular cylinders.

TI Recombination processes controlling the carrier lifetime in n(-)4H-SiC epilayers with low Z(1/2) concentrations SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID ENERGY-ELECTRON IRRADIATION; CHEMICAL-VAPOR-DEPOSITION; 4H-SIC EPITAXIAL LAYERS; SURFACE-RECOMBINATION; BULK LIFETIME; INTERFACE RECOMBINATION; TEMPERATURE-DEPENDENCE; SEMICONDUCTOR SURFACES; DEEP LEVELS; VELOCITY AB The dominant recombination processes controlling the carrier lifetime in n-type 4H-SiC epitaxial layers grown with low concentrations of the Z(1/2) defect (the dominant bulk lifetime killer), where Z(1/2) no longer determines the lifetime, have been investigated by studying the variation in the carrier lifetime with temperature. The temperature dependent lifetimes were obtained primarily by low-injection photoluminescence decay for several low-Z(1/2) epilayers over a wide temperature range. The results were fitted to simulations of the temperature dependent recombination rate, where bulk, surface and interface recombination was considered. No significant contribution from other bulk defects was observed, and upper limits to the bulk recombination rate were found to be consistent with the low Z(1/2) concentrations measured in these materials. There was also no significant contribution from carrier capture at the epilayer/substrate interface, which is consistent with behavior expected at low injection for low-doped epilayers grown on n(+) substrates. Corresponding high-injection measurements exhibited very different behavior, consistent with the surface/interface under flat-band conditions. Consequently, it is concluded that for low-Z(1/2) materials, control of the carrier lifetime has not been transferred from Z(1/2) to another bulk defect, but is instead dominated by surface and interface recombination. Simulations suggest that further enhancement of the total lifetime under the high injection conditions of a device structure would require very thick epilayers, effectively passivated surface and interface recombination and a further reduction in the remaining Z(1/2) concentrations. The temperature dependence of the low-injection carrier lifetime was also found to provide a method to estimate the surface band bending and the surface defect density.

We have constructed a fast near infrared (NIR) spectrometer and have made temporally and spectrally-resolved emission measurements during postdetonation combustion of pure pentaerythritol tetranitrate (PETN) charges and PETN charges doped with 10 wt % microparticles composed of silver (Ag) and aluminum (Al). We have observed postdetonation PETN emission spectra between 750 and 1500 nm at rates up to 46 992 spectra/s. The instrument captures the highly structured spectra immediately following breakout as well as the longer-lived broadband NIR emission signals from hot particles. The early spectra reveal spectral signatures related to PETN and the reacting constituents of the particles. The later spectra provide a means to infer the gray-body temperature history of the particles. (C) 2010 American Institute of Physics.

Noor TI Contact mechanisms and design principles for (Schottky and Ohmic) metal contacts to semiconductor nanowires SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID WIDE TEMPERATURE-RANGE; GAN NANOWIRES; SILICON NANOWIRES; BARRIER HEIGHTS; BAND-GAP; I-V; ELECTRICAL-TRANSPORT; SERIES RESISTANCE; INTERFACE STATES; COHESIVE ENERGY AB Contact mechanisms and design principles for (Ohmic and Schottky) metal (M) contacts to semiconductor nanowires (NWs) have been studied. The NWs have been assumed to be cylindrical. A unified model has been developed for the contacts. The model takes into consideration the amorphicity of the M/NW interface structure, the diameter dependence of the energy band gap, the barrier height modulation, and the fluctuations in both the barrier height and the applied bias. While the fluctuations in the barrier height are assumed to involve band tails, the fluctuations in applied bias are assumed to involve tiny Gaussian peaks. Several different features of the Ohmic and the Schottky contacts have been addressed. These include temperature and dimension dependencies of the current-voltage characteristics, the influence of the M/NW interface on the contact characteristics, the relationship between the barrier height and the ideality factor, and the barrier height reduction as a function of temperature. The model appears to be very general. It seems to explain all experimental results available to date in the literature. The calculated results are almost always in good correspondence with the experimental results. The study seemingly demonstrates an alternative to the doping dependence of the Ohmic contacts. It elucidates the fundamental physics underlying M/NW contacts. It highlights means to yield low-resistivity Ohmic contacts by thermionic emission. It describes design criteria for both Ohmic and Schottky contacts. The design criteria for Ohmic contacts tend to address the long-term reliability concerns for devices. They explain also the behavior of both good and bad Ohmic contacts. All these may be the most striking attributes of the study. These attributes explain why Schottky contacts to NWs, with proper gate modulation, may act also as Schottky barrier transistors. (C) 2010 American Institute of Physics.

The "fatigue design diagram" (FDD) method has been described and demonstrated to determine the depth and magnitude of compression required to achieve the optimum high cycle fatigue strength, and to mitigate a given depth of damage characterized by the fatigue stress concentration factor, k(f). LPB surface treatment technology and the FDD method have been combined to successfully mitigate a wide variety of surface damage ranging from FOD to corrosion pits in titanium and steel gas turbine engine compressor and fan components. LPB mitigation of fretting-induced damage in Ti-6Al-4V in laboratory samples has now been extended to fan and compressor components. LPB tooling technology recently developed to allow the processing of the pressure faces of fan and compressor blade dovetails and mating disk slots is described. Fretting-induced microcracks that form at the pressure face edge of bedding on both the blade dovetail and the dovetail disk slots in Ti-6-4 compressor components can now be arrested by the introduction of deep stable compression in conventional computer numerical control (CNC) machine tools during manufacture or overhaul. The compressive residual stress field design method employing the FDD approach developed at Lambda Technologies is described in application to mitigate fretting damage. The depth and magnitude of compression and the fatigue and damage tolerance achieved are presented. It was found that microcracks as deep as 0.030 in. (0.75 mm) large enough to be readily detected by current nondestructive inspection (NDI) technology can be fully arrested by LPB. The depth of compression achieved could allow NDI screening followed by LPB processing of critical components to reliably restore fatigue performance and extend component life.

The derivation uses a Volterra-series model for the system response and yields expressions for both auto-spectra, where the output of only one degree-of-freedom is used, and cross-spectra, where the bispectral density contains multiple output-response time series. The proposed formulation is used to identify the presence and location of quadratic nonlinearities in multiple degree-of-freedom systems. Results show that the ability to detect and localize nonlinearity is heavily dependent on which particular bispectral density is utilized.

Experimental data show that replacement of conventional anode designs, which use graphite composites coated on copper foil, with a freestanding silicon-[single-walled carbon nanotube (SWCNT)] anode, can increase the usable anode capacity by up to 20 times. In this work, a series of calculations were performed to elucidate the relative improvement in battery energy density for such anodes paired with conventional LiCoO(2), LiFePO(4), and LiNiCoAlO(2) cathodes. Results for theoretical flat plate prismatic batteries comprising freestanding silicon-SWCNT anodes with conventional cathodes show energy densities of 275 Wh/kg and 600 Wh/L to be theoretically achievable; this is a 50% improvement over today's commercial cells.

By using a nonplanar resonator geometry in conjunction with mechanical stress in polycrystalline silicon (poly) gate layers, we create rigid and robust mechanical structures with efficient electromechanical transduction. We demonstrate polysilicon domes with capacitive pickup and arch-bridge resonators with piezoresistive readout. The small footprint of our MEMS structures enables on-chip integration of large arrays of resonators for RF signal processing or sensing applications. Their large surface-to-volume ratio in combination with high rigidity (that alleviates stiction associated with wet chemistry processing) can make these resonators particularly useful for sensors that require surface functionalization.

Using these measured data to obtain transfer functions from irregular following sea ship motions is complicated by the combined effects of very low encounter frequencies and the "folding" of the sea spectra. This results in having both overtaking and encountered waves of the same encounter frequency but different wavelengths. Computing transfer functions becomes untenable when the ship speed approaches the wave phase velocity, where the encounter spectrum has a mathematical singularity. St. Denis and Pierson (1953, "On the Motions of Ships in Confused Seas," Soc. Nay. Archit. Mar Eng., Trans., 61, pp. 280-357) suggested the basic relationships between response ship motions or moments that can be developed in the wave frequency domain at the outset. The St. Denis Pierson method is based on a linear theory and works well when the ship response regime is linear or weakly nonlinear However, for high-speed craft operating at different headings where the problems are nonlinear; especially strongly nonlinear, the St. Denis Pierson assumptions will break down inducing error (1953, "On the Motions of Ships in Confused Seas," Soc. Nay. Archit. Mar Eng., Trans., 61, pp. 280-357). Furthermore, using the frequency resolution method to remove the singularity point may also induce errors, especially when the singularity point is located near the peak of stationary frequency. How to obtain the correct frequency resolution in the local region of singularity point is still an unsolved problem. In this study, we will propose a new method capable of predicting ship response motions for crafts with nonlinear or strongly nonlinear behaviors quantitatively. For example, using this method, one can use measured ship motion data in head seas to predict the motions of the ship at high speed in following seas. The new method has six steps, including using a filter to eliminate those unexpected modes that are not from incident waves, inertial motions, or nonlinear interactions, and applying a higher-order Taylor expansion to eliminate the singularity point. We refer to the new method as the Lin-Hoyt method, which agrees reasonably well with computations of the nonlinear "digital, self-consistent, ship experimental laboratory ship motion model," also known as DiSSEL (2006, "Numerical Modeling of Nonlinear Interactions Between Ships and Surface Gravity Waves II: Ship Boundary Condition," J. Ship Res., 50(2), pp. 181-186). We also use experimental head sea data to validate the simulations of DiSSEL. The Lin-Hoyt method is fast and inexpensive. The differences in the results of the numerical simulations obtained by the Lin-Hoyt method and other linear methods diverge rapidly with increased forward ship speed due to the nonlinearity of ship motion responses.

The design will be driven by the unique biomechanics specific to this fracture location. Materials and Methods: A finite element model of a fractured human mandible was created using computed tomography scans. The boundary conditions included simulating molar, canine, and incisal loading. The bone plate design process included a shape optimization routine and design parameter analysis using the model. The optimized bone plate design was finally compared with standard bone plate configurations according to stress and strain measures. Results: Compared with the miniplate combination, the Inter Flex III plate, with the same thickness and just 14% more implanted volume, had only 55% of the plate stress and 25% less fracture strain under the strongest loads considered by the model. Compared with the band/fracture plate combination, the Inter Flex plate had 88% of the fracture strain and 74% of the plate stress, despite having only 60% of the plate volume. Conclusions: The results have demonstrated that the new optimized plate is a hybrid of fixation hardware with the small profile of the smallest miniplate configuration and the superior fixation strength and safety that exceeds that of the larger fracture plate configuration.

Thresholds were measured approximately one-half octave above the exposure frequency using a behavioral response paradigm featuring an adaptive staircase procedure. Preliminary data provide evidence of frequency-specific differences in TTS onset and growth, and increased susceptibility to auditory fatigue after exposure to 3-kHz tones compared to data obtained two years earlier.

Coy, Lawrence TI A Spectral Parameterization of Drag, Eddy Diffusion, and Wave Heating for a Three-Dimensional Flow Induced by Breaking Gravity Waves SO JOURNAL OF THE ATMOSPHERIC SCIENCES LA English DT Article ID ELIASSEN-PALM FLUX; MIDDLE ATMOSPHERE; GENERAL-CIRCULATION; LOWER THERMOSPHERE; LOWER STRATOSPHERE; PLANETARY-WAVES; MOUNTAIN WAVES; DIURNAL TIDE; MESOSPHERE; PROPAGATION AB There are three distinct processes by which upward-propagating gravity waves influence the large-scale dynamics and energetics of the middle atmosphere: (i) nonlocalized transport of momentum through wave propagation in three dimensions that remotely redistributes atmospheric momentum in both zonal and meridional directions from wave generation to wave dissipation regions; (ii) localized diffusive transport of momentum, heat, and tracers due to mixing induced by wave breaking; and (iii) localized transport of heat by perturbing wave structures due to dissipation that redistributes the thermal energy within a finite domain. These effects become most significant for breaking waves when momentum drag, eddy diffusion, and wave heating- the "breaking trinity"-are all imposed on the background state. This paper develops a 3D parameterization scheme that self-consistently includes the breaking trinity in large-scale numerical models. The 3D parameterization scheme is developed based on the general relationship between the wave action flux and the subgrid-scale momentum and heat fluxes developed by Zhu in 1987 and a mapping approximation between the wave source spectrum and momentum deposition distribution developed by Alexander and Dunkerton in 1999. For a set of given input wind and temperature profiles at each model grid, the parameterization scheme outputs the vertical profiles of the subgrid-scale force terms together with the eddy diffusion coefficients in the momentum and energy equations for a 3D background flow.

The presence of TaB2 inhibited gram growth of TaC and Increased the hardness compared to pure TaC. If a coarse TaC powder was used, the compositions did not densify In contrast, pure nano-TaC was pressureless sintered at 1800 degrees C by the addition of 2 wt.% carbon introduced as carbon black or graphite The introduction of carbon black resulted in fully dense TaC ceramics at temperatures as low as 1500 degrees C. The grain size of nominally pure TaC ceramics was a strong function of carbon stoichiometry. Enhanced grain size in sub-stoichiometric TaC, compared to stoichiometric TaC, was observed Additional work is necessary to optimize processing parameters and evaluate the properties of ceramics in the TaC-TaB2-C system.

These viruses infect eukaryotic algal hosts from both fresh and marine waters, and are an Important component of aqueous environments. They play important roles in the dynamics of algal blooms, nutrient cycling, algal community structure, and possibly gene transfer between organisms As such, it is important to identify new viruses within the Phycodnaviridae family. Biological laser printing (BioLP) was used to Isolate single virus particles from solution.

TI Mobile autonomous process sampling within coastal ocean observing systems SO LIMNOLOGY AND OCEANOGRAPHY-METHODS LA English DT Article ID INTERMEDIATE NEPHELOID LAYERS; MARINE INVERTEBRATE LARVAE; POPULATION CONNECTIVITY; NORTHERN CALIFORNIA; ATLANTIC BIGHT; BIVALVE LARVAE; MONTEREY BAY; TRANSPORT; NUTRIENT AB Predicting when and where key oceanic processes will be encountered is problematic in dynamic coastal waters where diverse physical, chemical, and biological factors interact in varied and rapidly changing combinations. Defining key processes often requires efficient sampling of specific water masses and prompt sample return for subsequent analyses. This compound challenge motivated our efforts to develop mobile autonomous process sampling (MAPS) for use with autonomous underwater vehicles (AUVs). With this system, features are recognized by artificial intelligence that integrates AUV sensor data to estimate probabilistic states for adaptive control of survey navigation and triggering of targeted water samplers. To demonstrate the utility of the MAPS/AUV system, we focused on intermediate nepheloid layers (INLs), episodic transport events that may play a role in zooplankton ecology. During multiple field tests in Monterey Bay, California, the MAPS/AUV system recognized, mapped, and sampled INLs. Invertebrate larvae contained in the water samples were subsequently characterized with molecular probes developed for high-throughput screening. Preliminary results support the hypothesis that INLs function as vehicles for episodic larval transport. Applying MAPS within a greater coastal ocean observing system permitted description of regional oceanographic dynamics that influenced the patterns and scales of INL and larval transport.

Evaluation Measures: Patient healthcare utilization, financial, clinical, and humanistic outcomes. Absolute measures were translated into effect size and incorporated into a scorecard. Research Design: Actual outcomes for program participants were compared with outcomes predicted in the absence of disease management. The predictive equations were established from regression models based on historical control groups (n = 39,217). Z scores were calculated for the humanistic measures obtained through a mailed survey. Data Collection Methods: Administrative records containing medical claims, patient demographics and characteristics, and program participation status were linked using an encrypted patient identifier (n = 57,489). The study time frame is 1 year prior to program inception through 2 years afterward (October 2005-September 2008). A historical control group was identified with the baseline year starting October 2003 and a 1-year follow-up period starting October 2004. A survey was administered to a subset of participants 6 months after baseline assessment (39% response rate). Results: Within the observation window-24 months for asthma and congestive heart failure, and 15 months for the diabetes program-we observed modest reductions in hospital days and healthcare cost for all 3 programs and reductions in emergency visits for 2 programs. Most clinical outcomes moved in the direction anticipated. Conclusions: The scorecard provided a useful tool to track performance of 3 regional contractors for each of 3 diseases and over time.

TI Low-Temperature Carburization of the Ni-base Superalloy IN718: Improvements in Surface Hardness and Crevice Corrosion Resistance SO METALLURGICAL AND MATERIALS TRANSACTIONS A-PHYSICAL METALLURGY AND MATERIALS SCIENCE LA English DT Article ID AUSTENITIC STAINLESS-STEEL; PARAEQUILIBRIUM CARBURIZATION; CARBON SUPERSATURATION; NICKEL; DIFFUSION; CHROMIUM; ALLOY; PRECIPITATION; INCONEL-718; VOLUME AB "Case-hardening" of the Ni-base superalloy IN718 has been achieved by low-temperature gas-phase carburization. After carburization under optimum conditions, the hardened surface layer (the "case") has about twice the hardness of the core (HV of a parts per thousand 800) and contains a parts per thousand 12 at pct carbon in interstitial solid solution. This causes a lattice parameter expansion of a parts per thousand 1 pct perpendicular to the surface and, because of the mechanical constraint provided by the noncarburized core below, develops a large biaxial surface compressive residual stress (a parts per thousand 1.9 GPa) parallel to the surface. Microstructural studies and X-ray diffractometry reveal no carbide precipitates in the case. In agreement with this observation, low-temperature carburization does not compromise the ductility and actually improves the crevice corrosion resistance of the alloy.

In this study, we begin to explore the ncRNA diversity in four recently sequenced environmental Vibrio species (Vibrio alginolyticus 40B, Wino communis 1DA3, Vibrio mimicus VM573 and Vibrio campbellii BAA-1116) by performing in silico searches using Infernal and Rfam for the identification of putative ncRNA-encoding genes This search method resulted in the identification of 31-38 putative ncRNA genes per species and the total ncRNA catalogue spanned an assortment of regulatory mechanisms (riboswitches, cis-encoded ncRNAs, trans-encoded ncRNAs, modulators of protein activity, ribonucleoproteins, transcription termination ncRNAs and unknown). We chose to experimentally validate the identifications for V campbellii BAA-1116 using a microarray-based expression profiling strategy. Transcript hybridization to tiled probes targeting annotated V. campbellii BAA-1116 intergenic regions revealed that 21 of the 38 predicted ncRNA genes were expressed in mid-exponential-phase cultures grown in nutrient-rich medium. The microarray findings were confirmed by testing a subset of three highly expressed (6S, tmRNA and TPP-2) and three moderately expressed (CsrB, GcvB and purine) ncRNAs via reverse transcription PCR. Our findings provide new information on the diversity of ncRNA in environmental vibrios while simultaneously promoting a more accurate annotation of genomic intergenic regions C1 [Silveira, Ana Cristina G.; Thompson, Fabiano L.] Univ Fed Rio de Janeiro, Microbiol Lab, Inst Biol, BR-21941590 Rio De Janeiro, Brazil.

Particularly difficult mixed-agency dilemmas occur when a military psychiatrist, psychologist, or social worker encounters an apparent conflict between an ethical obligation-enumerated in a professional code of ethics-and a federal statute. This article explores ethical-legal conflicts for uniformed mental health providers. Three case vignettes illustrate situations in which military providers may find themselves stuck between incongruent ethical and legal demands. The authors conclude with several recommendations designed to prevent and resolve ethical-legal conflicts for military mental health providers. C1 [Johnson, W.

TI Residual Mosquito Barrier Treatments on US Military Camouflage Netting in a Southern California Desert Environment SO MILITARY MEDICINE LA English DT Article; Proceedings Paper CT 75th Annual Meeting of the American-Mosquito-Control-Association CY APR 06, 2009 CL New Orleans, LA SP Amer Mosquito Control Assoc ID FIELD-EVALUATION; MALARIA VECTORS; INSECTICIDE; BIFENTHRIN; PERMETHRIN; PROTECTION; VEGETATION; AUSTRALIA; MALATHION; DIPTERA AB Treating perimeters of vegetation with residual insecticides for protection from mosquito vectors has potential for U.S. military force health protection. However, for current U.S. military operations in hot-arid environments with little or no vegetation, residual applications on portable artificial materials may be a viable alternative. We evaluated bifenthrin residual treatments of U.S. military camouflage netting under hot-arid field conditions in a desert area in southern California exposed to abundant wild Culex tarsalis mosquitoes. We assessed the ability of the treatment to reduce the numbers of mosquitoes penetrating perimeters of netting and reaching CO(2)-baited mosquito traps. Treated camouflage netting barriers reduced mosquitoes by >= 50% for 7-14 days and by 20-35% for 21-28 days compared to untreated barriers. Although reductions may be translated into reductions in risk of exposure to mosquito-borne diseases, we emphasize that barrier treatments should be a component in a suite of insect control measures to be effective.

Methods: Retrospective study of 4 consecutive patients who underwent NSRH/PLND for stage IB1-IIB cervical carcinoma was conducted. Resection of the cardinal and uterosacral ligaments was performed with the Ligasure Atlas. Pelvic autonomic nerve dissection and lymphadenectomy were completed with the bipolar shears. Outcomes were collectively analyzed. Results: Mean operative time was 251 minutes (range, 230-265). Blood loss averaged 625 mL (range, 400-900). Average LOS was 5 days (range, 4-5). Average duration until normal postvoid residual volume was 17 days (range, 10-24). No perioperative complications were encountered. Conclusion: Bipolar surgical instrumentation offers many advantages. The Ligasure Atlas provides efficient sealing and division of vascular pedicles, while the bipolar shears allow precise and fine dissection. Our results demonstrate the "bipolar sealer and shears technique" a preferable method of NSRH/PLND. C1 [Shen-Gunther, Jane] USN, San Diego Med Ctr, Gynecol Oncol Serv, San Diego, CA 92134 USA.

Removal of the tumor is usually curative, and the syndrome is associated with the presence, rather than the history, of tumor. We present a case in which a 25-year-old, Hispanic woman presented with seizures, memory loss, and unusual behavioral changes. The woman had a teratoma removed 2 months earlier. Because of the time course, a paraneoplastic syndrome was initially considered unlikely. Brain imaging, electroencephalography (EEG) and neurologic work-up were negative. The patient was treated for a suspected somatoform disorder and psychosis. Based on the clinical picture, the working diagnosis was changed to delirium due to paraneoplastic limbic encephalitis. A course of intravenous immunoglobins (IVIg), and high dose steroids was administered. The patient's symptoms improved, and she was discharged home.

The forecasted surface winds over the southeast Pacific compare favorably with available observations. According to the forecasts and sensitivity simulations, the Southeast Pacific high pressure system(SEPH) plays a primary role in driving the CLLCJ. The Andes significantly intensify the CLLCJ mainly through interacting with the SEPH and anchoring a baroclinic zone along the Chilean coast. The land-sea differential heating also enhances the CLLCJ by strengthening the coastal baroclinic zone. Based on the location of the SEPH center, the CLLCJ can be separated into two types: a strong-forcing jet, with the SEPH close to the central Chilean coastline; and a weak-forcing jet, with the SEPH centered far away from the coastline. The former is much more intense and associated with stronger interaction between the SEPH and the Andes. The CLLCJ is slightly supergeostrophic within the marine boundary layer top inversion, where weak easterlies develop, and subgeostrophic in the turbulent boundary layer below, where westerlies are present. The inversion easterlies induce strong subsidence along the coast, which contributes to the formation of the coastal low and the coastal baroclinic zone.

For the 73 TCs that intensified to typhoon intensity during their lifetimes, the 33% and 67% respective percentiles of R15 at tropical storm intensity and at typhoon intensity are used to categorize small, medium, and large TCs. Whereas many of the small TCs form from an easterly wave synoptic pattern, the monsoon-related formation patterns are favorable for forming medium to large TCs. Most of these 73 TCs stay in the same size category during intensification, which implies specific physical mechanisms for maintaining TC size in the basin. The 18 persistently large TCs from the tropical storm to the typhoon stage mostly have northwestward or north-northwestward tracks, while the 16 persistently small TCs either move westward-northwestward in lower latitudes or develop at higher latitudes with various track types. For the large TCs, strong low-level southwesterly winds exist in the outer core region south of the TC center throughout the intensification period. The small TCs are more influenced by the subtropical high during intensification. The conclusion is that it is the low-level environment that determines the difference between large and small size storms during the early intensification period in the western North Pacific.

Using the cumulative distribution functions of 24-h intensity changes from the 2003-08 best-track data, four intensity change bins are defined: rapidly intensifying (RI), intensifying, neutral, and weakening. The Navy Operational Global Atmospheric Prediction System daily 0000 and 1200 UTC global analysis and Tropical Rainfall Measuring Mission Microwave Imager data are then used as proxies for the real atmosphere, and composites of various environmental fields believed relevant to TC intensity change are made in the vicinity of the TCs. These composites give the average characteristics near the TC, prior to undergoing a given intensity change episode. For the environmental variables, statistically significant differences are examined between RI storms and the other groups. While some environmental differences were found between RI and weakening/neutral TCs in both basins, an interesting result from this study is that the environment of RI TCs and intensifying TCs is quite similar. This indicates that the rate of intensification is only weakly dependent on the environmental conditions, on average, provided the environment is favorable. Notable exceptions were that in the WPAC, RI events occurred in environments with significantly larger conditional instability than intensifying events. In the ATL, RI events occurred in environments with weaker deep-layer shear than intensifying events. An important finding of this work is that SSTs are similar between intensifying and rapidly intensifying TCs, indicating that the rate of intensification is not critically dependent on SST. The TCs in both basins were more intense prior to undergoing an RI episode than an intensifying or neutral episode. In the WPAC, the three groups had similar translational speeds and headings, and average initial position. In the ATL, RI storms were located farther south than intensifying and neutral storms, and had a larger translational speed and a more westward component to the heading.

An efficient and dynamically consistent TC vortex relocation scheme for the WRF terrain-following mass coordinate has been developed to improve the first guess of the TC analysis, and hence improves the tropical cyclone initialization. The vortex relocation scheme separates the first-guess atmospheric flow into a TC circulation and environmental flow, relocates the TC circulation to its observed location, and adds the relocated TC circulation back to the environmental flow to obtain the updated first guess with a correct TC position. Analysis of these typhoon cases indicates that the relocation procedure moves the typhoon circulation to the observed typhoon position without generating discontinuities or sharp gradients in the first guess. Numerical experiments with and without the vortex relocation procedure for Typhoons Sinlaku, Jangmi, and Linfa forecasts show that about 67% of the first-guess fields need a vortex relocation to correct typhoon position errors while eliminates the topographical effect. As the vortex relocation effectively removes the typhoon position errors in the analysis, the simulated typhoon tracks are considerably improved for all forecast times, especially in the early periods as large adjustments appeared without the vortex relocation. Comparison of the horizontal and vertical vortex structures shows that large errors in the first-guess fields due to an incorrect typhoon position are eliminated by the vortex relocation scheme and that the analyzed typhoon circulation is stronger and more symmetric without distortions, and better agrees with observations. The result suggests that the main difficulty of objective analysis methods [e. g., three-dimensional variational data assimilation (3DVAR)], in TC analysis comes from poor first-guess fields with incorrect TC positions rather than not enough model resolution or observations. In addition, by computing the eccentricity and correlation of the axes of the initial typhoon circulation, the distorted typhoon circulation caused by the position error without the vortex relocation scheme is demonstrated to be responsible for larger track errors. Therefore, by eliminating the typhoon position error in the first guess that avoids a distorted initial typhoon circulation, the vortex relocation scheme is able to improve the ARW-WRF typhoon initialization and forecasts particularly when using data assimilation update cycling.

When exposed on one side the F coverage saturates at 25% (C(4)F), which is optically transparent, over 6 orders of magnitude more resistive than graphene, and readily patterned. Density functional calculations for varying coverages indicate that a C(4)F configuration is lowest in energy and that the calculated band gap increases with increasing coverage, becoming 2.93 eV for one C(4)F configuration. During defluorination, we find hydrazine treatment effectively removes fluorine while retaining graphene's carbon skeleton. The same films may be fluorinated on both sides by transferring graphene to a silicon-on-insulator substrate enabling XeF(2) gas to etch the Si underlayer and fluorinate the backside of the graphene film to form perfluorographane (CF) for which calculated the band gap is 3.07 eV. Our results indicate single-side fluorination provides the necessary electronic and optical changes to be practical for graphene device applications.

TI Intrinsic magnetism at silicon surfaces SO NATURE COMMUNICATIONS LA English DT Article ID AB-INITIO; SPIN; RECONSTRUCTION; SI(557)-AU; INSULATOR; CHAINS; OXIDE AB It has been a long-standing goal to create magnetism in a non-magnetic material by manipulating its structure at the nanoscale. Many structural defects have unpaired spins; an ordered arrangement of these can create a magnetically ordered state. In this article we predict theoretically that stepped silicon surfaces stabilized by adsorbed gold achieve this state by self-assembly, creating chains of polarized electron spins with atomically precise structural order. The spins are localized at silicon step edges having the form of graphitic ribbons. The predicted magnetic state is supported by recent experimental observations, such as the coexistence of double-and triple-period distortions and the absence of edge states in photoemission. Ordered arrays of surface spins can be accessed by probes with single-spin sensitivity, such as spin-polarized scanning tunnelling microscopy. The integration of structural and magnetic order is crucial for technologies involving spin-based computation and storage at the atomic level.

Wallcraft, Alan Shinoda, Toshiaki Yeager, Stephen TI Patterns of Indian Ocean sea-level change in a warming climate SO NATURE GEOSCIENCE LA English DT Article ID RISE; SURFACE; TRENDS AB Global sea level has risen during the past decades as a result of thermal expansion of the warming ocean and freshwater addition from melting continental ice(1). However, sea-level rise is not globally uniform(1-5). Regional sea levels can be affected by changes in atmospheric or oceanic circulation. As long-term observational records are scarce, regional changes in sea level in the Indian Ocean are poorly constrained. Yet estimates of future sea-level changes are essential for effective risk assessment(2). Here we combine in situ and satellite observations of Indian Ocean sea level with climate-model simulations, to identify a distinct spatial pattern of sea-level rise since the 1960s. We find that sea level has decreased substantially in the south tropical Indian Ocean whereas it has increased elsewhere. This pattern is driven by changing surface winds associated with a combined invigoration of the Indian Ocean Hadley and Walker cells, patterns of atmospheric overturning circulation in the north-south and east-west direction, respectively, which is partly attributable to rising levels of atmospheric greenhouse gases. We conclude that-if ongoing anthropogenic warming dominates natural variability-the pattern we detected is likely to persist and to increase the environmental stress on some coasts and islands in the Indian Ocean.

QDs are highly sensitive to charge-transfer processes, which can alter their optical properties. Here, we demonstrate that QD-dopamine-peptide bioconjugates can function as charge-transfer coupled pH sensors. Dopamine is normally characterized by two intrinsic redox properties: a Nernstian dependence of formal potential on pH and oxidation of hydroquinone to quinone by O(2) at basic pH. We show that the latter quinone can function as an electron acceptor quenching QD photoluminescence in a manner that depends directly on pH. We characterize the pH-dependent QD quenching using both electrochemistry and spectroscopy. QD-dopamine conjugates were also used as pH sensors that measured changes in cytoplasmic pH as cells underwent drug-induced alkalosis. A detailed mechanism describing the QD quenching processes that is consistent with dopamine's inherent redox chemistry is presented.

The searcher is constrained by maximum limits on the consumption of one or more resources such as time, fuel, and risk along any path. We develop a specialized branch-and-bound algorithm for this problem that uses several network reduction procedures as well as a new bounding technique based on Lagrangian relaxation and network expansion. The resulting algorithm outperforms a state-of-the-art algorithm for solving time-constrained problems and also is the first algorithm to solve multi-constrained problems.

Because new members of the solar neighborhood tend towards later spectral types, infrared parallax programs are particularly desirable. Therefore, the astrometric quality of the new infrared camera, FanCam, developed by the Virginia Astronomical Instrumentation Laboratory (VAIL) for the 31-in. (0.8 m) Tinsley reflector at Fan Mountain Observatory was assessed using 68 J-band exposures of an open cluster, NGC 2420, over a range of hour angles during 2005. Positions of 16 astrometric evaluation stars were measured and the repeatability of those positions was evaluated using the mean error in a single observation of unit weight. Overall, a precision of 1.3 +/- 0.7 mu m in x (RA) and 1.3 +/- 0.8 mu m in y (Dec) was attained, which corresponds to 0.04" +/- 0.02" in each axis. Although greater precision is expected from CCDs in the visual and near-infrared, this instrument can achieve precision similar to that of the ESO NTT infrared parallax program. Therefore, measuring parallaxes in the infrared would be feasible using this equipment. If initiated, such a program could provide essential distances for brown dwarfs and very low mass stars that would contribute significantly to the solar neighborhood census.

TI Optimization of irradiation configuration in laser fusion utilizing self-organizing electrodynamic system SO PHYSICS OF PLASMAS LA English DT Article ID CONSTRAINED GLOBAL OPTIMIZATION; INERTIAL CONFINEMENT FUSION; HIGH-GAIN; UNIFORMITY; IGNITION; TARGETS; REACTOR; ENERGY; PELLET AB A simple numerical method to determine an optimum beam configuration for highly uniform irradiation is proposed for direct-drive laser fusion systems and is applied to an arbitrary number of laser beams, NB. Driven by the Coulomb repulsion force, NB randomly distributed like charges move on a spherical surface to settle with a stable configuration having the minimum Coulomb energy for the system. Such resultant charge configurations practically do not depend on the initial conditions, and thus the solutions are very robust and unique. The irradiation uniformity is numerically assessed by overlapping NB beam patterns and calculating the laser absorption based on various spatial absorption patterns for the individual beams. The present method provides some improved illumination configurations for laser fusion compared with previously proposed designs. In particular, new coordinates for N(B)=48 and 72 are found to give an extraordinarily higher uniformity than for other numbers of NB. The influence of system imperfection on the irradiation uniformity is also discussed. (C) 2010 American Institute of Physics.

Internship training and postdoctoral supervision are key to producing competent military psychologists that can simultaneously serve effectively as commissioned officers. The context of supervision has evolved in recent years as the majority of military psychologists are deployed to the combat theater and many are tasked with nontraditional operational roles. This article explores the key ethical considerations faced by supervisors who prepare psychology interns, postdoctoral residents, or civilian psychologists for high-risk military roles in a time of war. Recommendations are provided for both clinical supervisors and military psychology leaders. C1 [Johnson, W. Brad] USN Acad, Dept Leadership Eth & Law, Annapolis, MD 21402 USA.

TI End-to-end system test for solid-state microdosemeters SO RADIATION PROTECTION DOSIMETRY LA English DT Article ID RADIATION QUALITY AB The gold standard in microdosemeters has been the tissue equivalent proportional counter (TEPC) that utilises a gas cavity. An alternative is the solid-state microdosemeter that replaces the gas with a condensed phase (silicon) detector with microscopic sensitive volumes. Calibrations of gas and solid-state microdosemeters are generally carried out using radiation sources built into the detector that impose restrictions on their handling, transportation and licensing in accordance with the regulations from international, national and local nuclear regulatory bodies. Here a novel method is presented for carrying out a calibration and end-to-end system test of a microdosemeter using low-energy photons as the initiating energy source, thus obviating the need for a regulated ionising radiation source. This technique may be utilised to calibrate both a solid-state microdosemeter and, with modification, a TEPC with the higher average ionisation energy of a gas. C1 [Pisacane, V. L.; Dicello, J.

Here we demonstrate how the method can be used to monitor viral RNA in infected cells. We compared the results of the LNA flow-FISH with other methods of quantifying virus replication, including the use of an enhanced green fluorescent protein (EGFP) viral construct and quantitative reverse-transcription polymerase chain reaction. We found that an LNA probe complementary to Sindbis virus RNA is able to track the increase in viral RNA over time in early infection. In addition, this method is comparable to the EGFP construct in sensitivity, with both peaking around 3 h and at the same level of infected cells. Finally, we observed that the LNA flow-FISH method responds to the decrease in levels of viral RNA caused by antiviral medication. This technique represents a straightforward way to monitor viral infection in cells and is easily applicable to any virus.

Two sites were studied: a rural hospital in Bardoli and an urban hospital in Surat. HIV-associated stigma among healthcare workers (N = 170) was assessed using a Stigma Index. Overall, analyses suggest an increase in medical education was found to be associated with higher stigmatisation (p < 0.001).

TI Consistent Tropical Cyclone Wind and Wave Forecasts for the US Navy SO WEATHER AND FORECASTING LA English DT Article ID TRAPPED-FETCH WAVES; PREDICTION SYSTEM; MODEL; OCEAN; ASSIMILATION; CLIMATOLOGY; PERSISTENCE; CURRENTS; NCEP AB A new algorithm to generate wave heights consistent with tropical cyclone official forecasts from the Joint Typhoon Warning Center (JTWC) has been developed. The process involves generating synthetic observations from the forecast track and the 34-, 50-, and 64-kt wind radii. The JTWC estimate of the radius of maximum winds is used in the algorithm to generate observations for the forecast intensity (wind), and the JTWC-estimated radius of the outermost closed isobar is used to assign observations at the outermost extent of the tropical cyclone circulation. These observations are then interpolated to a high-resolution latitude-longitude grid covering the entire extent of the circulation. Finally, numerical weather prediction (NWP) model fields are obtained for each forecast time, the NWP model forecast tropical cyclone is removed from these fields, and the new JTWC vortex is inserted without blending zones between the vortex and the background. These modified fields are then used as input into a wave model to generate waves consistent with the JTWC forecasts. The algorithm is applied to Typhoon Yagi (2006), in anticipation of which U. S. Navy ships were moved from Tokyo Bay to an area off the southeastern coast of Kyushu. The decision to move (sortie) the ships was based on NWP model-driven long-range wave forecasts that indicated high seas impacting the coast in the vicinity of Tokyo Bay. The sortie decision was made approximately 84 h in advance of the high seas in order to give ships time to steam the approximately 500 n mi to safety. Results from the new algorithm indicate that the high seas would not affect the coast near Tokyo Bay within 84 h. This specific forecast verifies, but altimeter observations show that it does not outperform, the NWP model-driven wave analysis and forecasts for this particular case. Overall, the performance of the new algorithm is dependent on the JTWC tropical cyclone forecast performance, which has generally outperformed those of the NWP model over the last several years.

TI High-order semi-implicit time-integrators for a triangular discontinuous Galerkin oceanic shallow water model SO INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN FLUIDS LA English DT Article DE discontinuous Galerkin; explicit; finite element; finite volume; implicit; semi-implicit; shallow water; triangle ID MONOMIAL CUBATURE RULES; NAVIER-STOKES EQUATIONS; SPECTRAL ELEMENT; COMPRESSIBLE FLOW; TSUNAMI; DISCRETIZATION; SIMULATIONS; COMPILATION; STROUD; SETS AB We extend the explicit in time high-order triangular discontinuous Galerkin (DG) method to semi-implicit (SI) and then apply the algorithm to the two-dimensional oceanic shallow water equations; we implement high-order SI time-integrators using the backward difference formulas from orders one to six. The reason for changing the time-integration method from explicit to SI is that explicit methods require a very small time step in order to maintain stability, especially for high-order DG methods. Changing the time-integration method to SI allows one to circumvent the stability criterion due to the gravity waves, which for most shallow water applications are the fastest waves in the system (the exception being supercritical flow where the Froude number is greater than one). The challenge of constructing a SI method for a DG model is that the DG machinery requires not only the standard finite element-type area integrals, but also the finite volume-type boundary integrals as well. These boundary integrals pose the biggest challenge in a SI discretization because they require the construction of a Riemann solver that is the true linear representation of the nonlinear Riemann problem; if this condition is not satisfied then the resulting numerical method will not be consistent with the continuous equations. In this paper we couple the SI time-integrators with the DG method while maintaining most of the usual attributes associated with DG methods such as: high-order accuracy (in both space and time), parallel efficiency, excellent stability, and conservation. The only property lost is that of a compact communication stencil typical of time-explicit DG methods; implicit methods will always require a much larger communication stencil. We apply the new high-order SI DG method to the shallow water equations and show results for many standard test cases of oceanic interest such as: standing, Kelvin and Rossby soliton waves, and the Stommel problem. The results show that the new high-order SI DG model, that has already been shown to yield exponentially convergent solutions in space for smooth problems, results in a more efficient model than its explicit counterpart. Furthermore, for those problems where the spatial resolution is sufficiently high compared with the length scales of the flow, the capacity to use high-order (HO) time-integrators is a necessary complement to the employment of HO space discretizations, since the total numerical error would be otherwise dominated by the time discretization error. In fact, in the limit of increasing spatial resolution, it makes little sense to use HO spatial discretizations coupled with low-order time discretizations.

TI First results on terrestrial gamma ray flashes from the Fermi Gamma-ray Burst Monitor SO JOURNAL OF GEOPHYSICAL RESEARCH-SPACE PHYSICS LA English DT Article ID BREAKDOWN; SPACE; SPRITES; AIR AB The Gamma-ray Burst Monitor (GBM) on the Fermi Gamma-ray Space Telescope detected 12 intense terrestrial gamma ray flashes (TGFs) during its first year of observation. Typical maximum energies for most of the TGFs are similar to 30 MeV, with one TGF having a 38 MeV photon; two of the TGFs are softer and longer than the others. After correcting for instrumental effects, a representative bright TGF is found to have a fluence of similar to 0.7 photons cm (2). Pulses are either symmetrical or have faster risetimes than fall times; they are well fit with Gaussian or lognormal functions. The fastest risetime observed was 7 mu s, constraining the source radius to be less than about 2 km from the velocity of light. TGFs with multiple pulses separated in time have been known since their discovery; the GBM sample also includes clear cases of partially overlapping pulses. Four TGFs are associated with lightning locations from the World Wide Lightning Location Network. With the several mu s absolute time accuracy of GBM, the time order can be confidently identified: one TGF occurred before the lightning, two were simultaneous, and one TGF occurred after the lightning.

TI Effect of doping and pressure on magnetism and lattice structure of iron-based superconductors SO PHYSICAL REVIEW B LA English DT Article ID WAVE AB Using first-principles calculations, we analyze structural and magnetic trends as a function of charge doping and pressure in BaFe(2)As(2), and compare to experimentally established facts. We find that density-functional theory, while accurately reproducing the structural and magnetic ordering at ambient pressure, fails to reproduce some structural trends as pressure is increased. Most notably, the Fe-As bond length which is a gauge of the magnitude of the magnetic moment, mu, is rigid in experiment but soft in calculation, indicating residual local Coulomb interactions. By calculating the magnitude of the magnetic ordering energy, we show that the disruption of magnetic order as a function of pressure or doping can be qualitatively reproduced but that in calculation, it is achieved through diminishment of vertical bar mu vertical bar, and therefore likely does not reflect the same physics as detected in experiment. We also find that the strength of the stripe order as a function of doping is strongly site dependent: magnetism decreases monotonically with the number of electrons doped at the Fe site but increases monotonically with the number of electrons doped at the Ba site. Intraplanar magnetic ordering energy (the difference between checkerboard and stripe orderings) and interplanar coupling both follow a similar trend. C1 [Johannes, M. D.; Mazin, I. I.; Parker, D.

Using a case control design this study's purpose was to explore, among a population of methamphetamine-dependent Caucasians, six putative single nucleotide polymorphisms previously found to be associated with methamphetamine dependence in Asian populations. A total of 193 non-psychotic males (117 methamphetamine-dependent and 76 controls) were genotyped for variants located in six genes (AKT1, ARRB2, BDNF, COMT, GSTP1, OPRM1). Genotypic and allelic frequencies, odds ratios, and 95% confidence intervals were calculated. None of the putative gene associations was significantly replicated in our sample of Caucasian men. Effect size comparisons suggest a trend toward allelic divergence for arrestin beta 2 (ARRB2) and glutathione S-transferase P1 (GSTP1) and allelic convergence for brain-derived neurotrophic factor (BDNF). Results provide preliminary support for further exploration and validation of candidate single nucleotide polymorphisms (SNPs) for methamphetamine (METH) dependence reported among Asian populations across other ethnic/ancestral groups.

TI upsilon cross section in p plus p collisions at root s=200 GeV SO PHYSICAL REVIEW D LA English DT Article ID NUCLEUS-NUCLEUS COLLISIONS; QUARK-GLUON PLASMA; J-PSI; SUPPRESSION; RESONANCES; DIMUON; GAMMA AB We report on a measurement of the gamma(1S + 2S + 3S) -> e(+)e(-) cross section at midrapidity in p + p collisions at root s = 200 GeV. We find the cross section to be 114 +/- 38(stat + fit)(-24)(+23)(syst) pb. Perturbative QCD calculations at next-to-leading order in the color evaporation model are in agreement with our measurement, while calculations in the color singlet model underestimate it by 2 sigma. Our result is consistent with the trend seen in world data as a function of the center-of-mass energy of the collision and extends the availability of gamma data to RHIC energies. The dielectron continuum in the invariant-mass range near the gamma is also studied to obtain a combined yield of e(+)e(-) pairs from the sum of the Drell-Yan process and b-(b) over bar production.

However, the efficient modification of QDs with complex biomolecules represents a significant challenge. Here, we describe a straightforward arylhydrazone approach for the chemoselective covalent modification of QDs that is compatible with neutral pH and micromolar concentrations of the peptide target. The kinetics of covalent modification can be monitored spectroscopically at 354 nm in the presence of the QD and average peptide/QD ratios from 2:1 to 11:1 were achieved with excellent control over the desired valency. These results suggest that aniline catalyzed hydrazone ligation has the potencial to provide a general method for the controlled assembly of a variety of nanoparticle-biomolecule hybrids.

We have determined the structure and polarization for a number of arrangements of Ca and Sr in a 2 x 2 x 2 supercell. The a and b lattice vectors are strained to match the lattice constants of the rotated Si(001) face. To set the context for the CSTO study, we also include simulations of the Si(001) constrained structures for CaTiO3 and SrTiO3. Our primary findings are that all Ca0.5Sr0.5TiO3 structures examined except one are ferroelectric, exhibiting polarizations ranging from 0.08 C/m(2) for the lowest energy configuration to about 0.26 C/m(2) for the higher energy configurations. We find that the configurations with larger polarizations have lower c/a ratios. The net polarization of the cell is the result of Ti-O ferroelectric displacements regulated by A-site cations.

SO BMC PUBLIC HEALTH LA English DT Article ID MENTAL-HEALTH PROBLEMS; MALE VIETNAM VETERANS; HOUSEHOLD DYSFUNCTION; NATIONAL SAMPLE; PTSD SYMPTOMS; COMBAT; ABUSE; MILITARY; ASSOCIATION; DEPLOYMENT AB Background: Posttraumatic stress disorder ( PTSD) has been associated with combat intensity, lack of social support, and adverse childhood factors among military personnel in previous studies. It has not been well established if adverse childhood experiences reported predeployment are independently associated with postdeployment PTSD. Methods: Data were evaluated from 8,391 male responders of the Recruit Assessment Program survey at Marine Corps Recruit Depot in San Diego who were deployed in support of military conflicts between September 2001 and June 2004. Using patient medical records to determine PTSD diagnoses, Cox proportional hazard modeling was performed to examine if adverse childhood experiences were independently associated with postdeployment PTSD. Results: After adjustment, those who reported adverse childhood experiences in more than one category were significantly more likely to be diagnosed with postdeployment PTSD. Specifically, childhood physical neglect was mostly strongly associated with postdeployment PTSD. Conclusions: Findings suggest that Marines who experience multiple types of adverse childhood experiences may be at increased risk for postdeployment PTSD. It is possible, however, that these results indicate that men willing to report childhood adverse experiences are also more willing to seek care for PTSD.

We separate the steady-state solution of the appropriate density matrix element into the sum of three resonances. The effect of each resonance on the overall absorption and dispersion experienced by the probe is studied as a function of the strengths of the two other fields. In the limit of low saturation, we reveal the physics of these resonances and associate them with atomic excitation pathways, which we explicitly explain in the bare-states picture.

Compared to oligo(phenylene vinylene) (OPV)(3), the introduction of oxygen atoms into the phenyl ring for OPVQ leads to the appearance of a narrow transmission band at close proximity to the electrode Fermi levels. This band allows OPVQ to operate as an efficient n-type conductor with a single molecular electron transfer efficiency approaching I G(0) (quantum conductance). The close location to the Fermi level and the narrow shape of the band lead to high and stable molecular conductivity even at a very low bias. The presence of an efficient transmission hand close to the electrode Fermi level explains experimentally observed high molecular conductance of OPVQ, which will allow this molecule to be used in low band gap molecular electronic devices.

We present the electronic structure, ionization energies, quasiparticle gap, and the excitation energies for the Si-14(CH3)(24) and the exact silicon analog of adamantane Si10H16 obtained at the all-electron level using the delta-self-consistent-field and transitional state methods within two different density functional models: (i) Perdew-Burke-Ernzerhof generalized gradient approximation and (ii) fully analytic density functional (ADFT) implementation with atom dependent potential. The ADFT is designed so that molecules separate into atoms having exact atomic energies. The calculations within the two models agree well, to within 0.25 eV for optical excitations. The effect of structural relaxation in the presence of electron-hole-pair excitations is examined to obtain its contribution to the luminescence Stokes shift. The spin-influence on exciton energies is also determined. Our calculations indicate overall decrease in the absorption, emission, quasiparticle, and highest occupied molecular orbital-lowest unoccupied molecular orbital gaps, ionization energies. Stokes shift, and exciton binding energy when passivating hydrogens in the Si10H16 are replaced with electron donating groups such as methyl (Me) and trimehylsilyl (-Si(Me)(3)).

TI Sun to 1 AU propagation and evolution of a slow streamer-blowout coronal mass ejection SO JOURNAL OF GEOPHYSICAL RESEARCH-SPACE PHYSICS LA English DT Article ID INTERPLANETARY MAGNETIC CLOUDS; FLUX-ROPES; SOLAR-WIND; LASCO OBSERVATIONS; SOHO LASCO; MODEL; HELICITY; ROTATION; EARTH; RECONNECTION AB We present a comprehensive analysis of the evolution of the classic, slow streamer blowout CME of 1 June 2008 observed by the STEREO twin spacecraft to infer relevant properties of the pre-eruption source region which includes a substantial portion of the coronal helmet streamer belt. The CME was directed similar to 40 degrees East of the Sun-Earth line and the Heliospheric Imager observations are consistent with the CME propagating essentially radially to 1 AU. The elongation-time J-map constructed from the STEREO-A HI images tracks the arrival of two density peaks that bound the magnetic flux rope ICME seen at STEREO-B on 6 June 2008. From the STEREO-A elongation-time plots we measure the ICME flux rope radial size R-c(t) and find it well approximated by the constant expansion value V-exp = 24.5 km/s obtained from the STEREO-B declining velocity profile within the magnetic cloud. The flux rope spatial orientation, determined by forward modeling fits to the STEREO COR2 and HI1 data, approaches the observed 1 AU flux rope orientation and suggests large-scale rotation during propagation, as predicted by recent numerical simulations. We compare the ICME flux content to the PFSS model coronal field for Carrington Rotation 2070 and find sufficient streamer belt flux to account for the observed ICME poloidal/twist flux if reconnection during CME initiation process is responsible for the conversion of overlying field into the flux rope twist component in the standard fashion. However, the PFSS model field cannot account for the ICME toroidal/axial flux component. We estimate the field strength of the pre-eruption sheared/axial component in the low corona and the timescales required to accumulate this energized pre-eruption configuration via differential rotation and flux cancelation by supergranular diffusion at the polarity inversion line. We show that both mechanisms are capable of generating the desired shear component over time periods of roughly 1-2 months. We discuss the implications for slow streamer-blowout CMEs arising as a natural consequence of the corona's re-adjustment to the long term evolutionary driving of the photospheric fields.

The ligands are made of a PEG segment appended with two thioctic acid (TA) or two dihydrolipoic acid (DHLA) anchoring groups, bis(TA)-PEG-OCH(3) or bis(DHLA)-PEG-OCH(3). The synthesis utilizes Michael addition to create a branch point at the end of a PEG chain combined with carbodiimide-coupling to attach two TA groups per PEG chain. Dispersions of CdSe-ZnS core-shell QDs and AuNPs with remarkable long-term colloidal stability at pHs ranging from 1.1 to 13.9 and in the presence of 2 M NaCl have been prepared and tested using these ligands. AuNPs with strong resistance to competition from dithiothreitol (as high as 1.5 M) have also been prepared. This opens up possibilities for using them as stable probes in a variety of bio-related studies where resistance to degradation at extreme pHs, at high electrolyte concentration, and in thiol-rich environments is highly desirable. The improved colloidal stability of nanocrystals afforded by the tetradentate ligands was further demonstrated via the assembly of stable QD-nuclear localization signal peptide bioconjugates that promoted intracellular uptake.

TI A new radio loudness diagnostic for active galaxies: a radio-to-mid-infrared parameter SO MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY LA English DT Article DE Galaxy: stellar content; galaxies: Seyfert; infrared: galaxies ID BLACK-HOLE MASS; SPITZER-SPACE-TELESCOPE; EXTENDED 12-MU-M SAMPLE; X-RAY LUMINOSITY; SEYFERT-GALAXIES; GALACTIC NUCLEI; STAR-FORMATION; LIMITED SAMPLE; MU-M; ENERGY-DISTRIBUTIONS AB We have studied the relationship between the nuclear (high-resolution) radio emission, at 8.4 GHz (3.6 cm) and 1.4 GHz (20 cm), the [O iv] lambda 25.89 mu m, [Ne iii] lambda 15.56 mu m and [Ne ii] lambda 12.81 mu m emission lines and the black hole mass accretion rate for a sample of Seyfert galaxies. In order to characterize the radio contribution for the Seyfert nuclei we used the 8.4 GHz/[O iv] ratio, assuming that [O iv] scales with the luminosity of the active galactic nuclei (AGN). From this we find that Seyfert 1s (i.e. Seyfert 1.0s, 1.2s and 1.5s) and Seyfert 2s (i.e. Seyfert 1.8s, 1.9s and 2.0s) have similar radio contributions, relative to the AGN. On the other hand, sources in which the [Ne ii] emission is dominated either by the AGN or star formation have statistically different radio contributions, with star formation dominated sources more 'radio loud', by a factor of similar to 2.8 on average, than AGN dominated sources. We show that star formation dominated sources with relatively larger radio contribution have smaller mass accretion rates. Overall, we suggest that 8.4 GHz/[O iv], or alternatively, 1.4 GHz/[O iv] ratios, can be used to characterize the radio contribution, relative to the AGN, without the limitation of previous methods that rely on optical observables.

The ends of the cylinder are coated with specularly reflecting aluminum to increase the signal by reflecting the stimulating light beam through the medium multiple times. The circumference of the cylinder is similarly coated to increase the fraction of the emitted light that is collected and sent into the slit of a spectrometer. Such a cell can greatly increase the signal measured by an analysis system without any modifications to the system. C1 [Lucke, Robert L.; Grun, Jacob] USN, Res Lab, Washington, DC 20375 USA.

TI FORMATION AND RECONNECTION OF THREE-DIMENSIONAL CURRENT SHEETS IN THE SOLAR CORONA SO ASTROPHYSICAL JOURNAL LA English DT Article DE Sun: activity; Sun: corona; Sun: magnetic topology ID HYPERBOLIC FLUX TUBES; MAGNETIC RECONNECTION; MASS EJECTIONS; ENERGY-RELEASE; FIELDS; EVOLUTION; DYNAMICS; MODEL; ERUPTIONS; BREAKOUT AB Current-sheet formation and magnetic reconnection are believed to be the basic physical processes responsible for much of the activity observed in astrophysical plasmas, such as the Sun's corona. We investigate these processes for a magnetic configuration consisting of a uniform background field and an embedded line dipole, a topology that is expected to be ubiquitous in the corona. This magnetic system is driven by a uniform horizontal flow applied at the line-tied photosphere. Although both the initial field and the driver are translationally symmetric, the resulting evolution is calculated using a fully three-dimensional (3D) magnetohydrodynamic simulation with adaptive mesh refinement that resolves the current sheet and reconnection dynamics in detail. The advantage of our approach is that it allows us to directly apply the vast body of knowledge gained from the many studies of two-dimensional (2D) reconnection to the fully 3D case. We find that a current sheet forms in close analogy to the classic Syrovatskii 2D mechanism, but the resulting evolution is different than expected. The current sheet is globally stable, showing no evidence for a disruption or a secondary instability even for aspect ratios as high as 80:1. The global evolution generally follows the standard Sweet-Parker 2D reconnection model except for an accelerated reconnection rate at a very thin current sheet, due to the tearing instability and the formation of magnetic islands. An interesting conclusion is that despite the formation of fully 3D structures at small scales, the system remains close to 2D at global scales. We discuss the implications of our results for observations of the solar corona. C1 [Edmondson, J. K.] NASA, Jet Prop Lab, Pasadena, CA 91109 USA. [Antiochos, S.

TI FERMI LARGE AREA TELESCOPE OBSERVATIONS OF THE SUPERNOVA REMNANT W28 (G6.4-0.1) SO ASTROPHYSICAL JOURNAL LA English DT Article DE acceleration of particles; cosmic rays; gamma rays: ISM; ISM: individual objects (W28, G6.4-0.1); ISM: supernova remnants ID GAMMA-RAY EMISSION; H-II REGIONS; SHOCKED MOLECULAR GAS; GALACTIC COSMIC-RAYS; MHZ OH MASERS; IC 443; DISCOVERY; OUTFLOW; CLOUDS; W44 AB We present detailed analysis of two gamma-ray sources, 1FGL J1801.3-2322c and 1FGL J1800.5-2359c, that have been found toward the supernova remnant (SNR) W28 with the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope. 1FGL J1801.3-2322c is found to be an extended source within the boundary of SNR W28, and to extensively overlap with the TeV gamma-ray source HESS J1801-233, which is associated with a dense molecular cloud interacting with the SNR. The gamma-ray spectrum measured with the LAT from 0.2 to 100 GeV can be described by a broken power-law function with a break at similar to 1 GeV and photon indices of 2.09 +/- 0.08 (stat) +/- 0.28 (sys) below the break and 2.74 +/- 0.06 (stat) +/- 0.09 (sys) above the break. Given the clear association between HESS J1801-233 and the shocked molecular cloud and a smoothly connected spectrum in the GeV-TeV band, we consider the origin of the gamma-ray emission in both GeV and TeV ranges to be the interaction between particles accelerated in the SNR and the molecular cloud. The decay of neutral pions produced in interactions between accelerated hadrons and dense molecular gas provides a reasonable explanation for the broadband gamma-ray spectrum. 1FGL J1800.5-2359c, located outside the southern boundary of SNR W28, cannot be resolved. An upper limit on the size of the gamma-ray emission was estimated to be similar to 16' using events above similar to 2 GeV under the assumption of a circular shape with uniform surface brightness. It appears to coincide with the TeV source HESS J1800-240B, which is considered to be associated with a dense molecular cloud that contains the ultra compact H II region W28A2 (G5.89-0.39). We found no significant gamma-ray emission in the LAT energy band at the positions of TeV sources HESS J1800-230A and HESS J1800-230C. The LAT data for HESS J1800-230A combined with the TeV data points indicate a spectral break between 10 GeV and 100 GeV. C1 [Abdo, A. A.; Chekhtman, A.; Dermer, C. D.; Grove, J. E.; Johnson, W.

Specifically, we use a Markov Chain Monte Carlo method for sampling the posterior parameter distributions thus producing both point and interval estimates for parameters. The method is first used to identify both linear and nonlinear parameters in a multiple degree-of-freedom structural systems using free-decay vibrations. The approach is then applied to the problem of identifying the location, size, and depth of delamination in a model composite beam. The influence of additive Gaussian noise on the response data is explored with respect to the quality of the resulting parameter estimates. Published by Elsevier Ltd. C1 [Nichols, J. M.; Olson, C.

TI Magnetic moment degradation of nanowires in biological media: real-time monitoring with SQUID magnetometry SO NANOTECHNOLOGY LA English DT Article ID BICARBONATE SOLUTIONS; NICKEL NANOWIRES; DRUG-DELIVERY; NANOPARTICLES; OXIDE; COBALT; SPECTROSCOPY; HYPERTHERMIA; HYDROXIDE; CATALYSTS AB Magnetic nanoparticles are used throughout biology for applications from targeted drug and gene delivery to the labeling of cells. These nanoparticles typically react with the biological medium to which they are introduced, resulting in a diminished magnetic moment. The rate at which their magnetic moment is diminished limits their utility for targeting and can signal the unintended release of surface-functionalized biomolecules. A foreknowledge of the time-dependent degradation of the magnetic moment in a given medium can aid in the selection of the optimal buffering solution and in the prediction of a reasonable experimental time frame. With this goal in mind, we have developed a SQUID magnetometer based methodology for measuring the saturation magnetic moment of nanoparticles in real time while immersed in a biological medium. Measurements on Co and Ni nanowires in a variety of commonly used buffered salines demonstrated that the technique has the dynamic range and sensitivity to detect the rapid reduction in moment due to active corrosion as well as much more subtle changes from the formation of a passivating surface oxide layer. In order to correlate the magnetic moment reductions to these specific chemical processes, samples were additionally characterized using x-ray photoelectron spectroscopy, inductively coupled plasma spectroscopy and scanning electron microscopy. The most reactive buffers studied were found to be phosphate and carbonate based, which caused active corrosion of the Co nanowires but only a comparatively slow passivation of the Ni nanowires by oxidation.

TI Fast and slow carrier recombination transients in highly excited 4H-and 3C-SiC crystals at room temperature SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID AUGER RECOMBINATION; SURFACE RECOMBINATION; ABSORPTION; 4H; 3C; PARAMETERS; DEPENDENCE; LIFETIME; SILICON; 6H AB Nonequilibrium carrier recombination in highly excited epitaxial layers of 4H-SiC and free standing 3C-SiC was analyzed numerically and studied experimentally by the time-resolved free carrier absorption (FCA) technique. The measurement setup combined interband carrier excitation by a picosecond laser pulse and probing of carrier dynamics at excess carrier densities in the Delta N = 10(17)-10(20) cm(-3) range by optically or electronically delayed probe pulses, thus providing temporal resolution of 10 ps and 10 ns, respectively. FCA decay kinetics at different excitation levels and subsequent numerical modeling were used to determine the bulk lifetime, surface recombination velocity, and bimolecular (B) and Auger recombination (C) coefficients at 300 K. Bulk lifetimes of similar to 800 ns and similar to 65 ns were determined in 4H and 3C epitaxial layers, respectively. The numerical fitting of FCA kinetics in the 4H layer provided values of B = (1.2 +/- 0.4) x 10(-12) cm(3)/s and C = (7 +/- 4) x 10(-31) cm(6)/s at lower excitations while the Auger coefficient decreased to C = (0.8 +/- 0.2) x 10(-31) cm(6)/s at Delta N similar to 10(20) cm(-3) due to screening of the Coulomb-enhanced Auger recombination. In 3C crystals, these values were measured to be B = (2.0 +/- 0.5) x 10(-12) cm(3)/s and C = (2.0 +/- 0.5) x 10(-32) cm(6)/s. The tendency for a strongly increased surface recombination rate in 3C at high excitation conditions was observed experimentally and associated with the screening of the surface potential by the high density carrier plasma.

TI A Fundamental Study of the Transport Properties of Aqueous Superacid Solutions SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID PROTON CONDUCTIVITY; FIELD GRADIENT; HYDROXYL IONS; LIQUID WATER; SPIN ECHOES; ACID; MEMBRANES; SOLVATION; MECHANISM; DIFFUSION AB An extensive investigation of the transport properties of aqueous acid solutions was undertaken. The acids studied were trifluoromethanesulfonic (CF3SO3H), bis(trifluoromethanesulfonyl)imide [(CF3SO7)(2)NH], and para-toluenesulfonic (CH3C6H4SO3H), of which the first two are considered superacids. NMR measurements of self-diffusion coefficients (D), spin lattice relaxation times (T-1), and chemical shifts, in addition to ionic conductivity (sigma), viscosity (eta), and density measurements, were performed at 30 degrees C over the concentration range of 2-112 water to acid molecules. Results showed broad maxima in sigma for all three acids in the concentration range of 12-20 water to acid molecules. This coincided with minima in anion Ds and is attributed to a local molecular ordering, reduced solution dielectric permittivity, and increased ionic interactions. The location of the maxima in sigma correlates with what is observed for hydrated sulfonated perfluoropolymers such as Nation, which gives a maximum in ionic transport when the ratio of water to acid molecules is about 15-20. Of the three acids, bis(trifluoromethanesulfonyl)imide was found to be the least dependent on hydration level. The occurrence of the anticorrelation between the ionic conductivity maximum and the anion self-diffusion minimum supports excess proton mobility in this region and may offer additional information on the strength of hydrogen bonding in aqueous media as well as on the role of high acid concentration in the Grotthuss proton transport mechanism.

TI Resolving Sulfur Oxidation and Removal from Pt and Pt3Co Electrocatalysts Using in Situ X-ray Absorption Spectroscopy SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID PT/VULCAN CARBON ELECTROCATALYSTS; OXYGEN REDUCTION REACTION; MEMBRANE FUEL-CELLS; PLATINUM-ELECTRODE; ANION ADSORPTION; FINE-STRUCTURE; VIBRATIONAL SPECTROSCOPY; HYDROGEN ADSORPTION; SULFATE ADSORPTION; TRANSITION-METALS AB Adsorbed sulfur is a poison to the Pt catalysts used in proton exchange membrane fuel cells, but it can be removed by potential cycling. This process is studied for Si-poisoned nanoscale Pt- and Pt3Co- on Vulcan carbon (Pt/VC and Pt3Co/VC) in perchloric acid electrolyte using the Delta mu adsorbate isolation technique for in situ X-ray absorption spectroscopy. The Delta mu technique is modified to better distinguish the Delta mu signatures for H, O, and S-x on Pt. The resulting Delta mu analysis suggests that SO2 on nanoscale Pt is oxidized to bisulfate or sulfate species in two regions, near 1.05 V on the cluster edges of the Pt nanoparticle, and at higher potentials from the Pt(111) faces where oxygen is less strongly bound. The bisulfate or sulfate species desorb from the Pt surface at high potentials due to O(OH) adsorption/replacement and at low potentials due to loss of the Coulomb attraction between the bisulfate anion and the Pt. A similar oxidation process occurs for S-x-poisoned Pt3Co/VC, but at lower potentials because a ligand effect coming from Co shifts the oxidization potential of adsorbed SO2 to lower potentials while pushing OH adsorption to higher potentials. The spectroscopic results give insights into cyclic voltammetry data and are consistent with electrochemical cycling procedures for removing the sulfur.

Applications of functionalized sorbent polymers include preconcentrator devices, SPME fibers, membrane introduction systems, chromatographic stationary phases and coatings for chemical sensors. One common feature of a wide range of hazardous chemicals is their hydrogen bond (h-b) basicity. In this work, we report on the synthesis and characterization of a h-b acidic hyperbranched carbosilane fluoroalcohol based sorbent polymer (poly(methyldi(1,1,1-trifluoro-2-trifluoromethyl-2-hydroxypent-4-enyl)silane; HCSFA2), which is suitable for sorbing these hazardous h-b basic analytes. Multiple batches of HCSFA2 were characterized with routine composition, spectroscopic, thermal analysis, and inverse gas chromatography (iGC) to evaluate polymer physicochemical properties. In comparison with previously developed h-b acidic polymers (e.g., FPOL and SXFA), HCSFA2 exhibits a sorption improvement of 10-15 fold for h-b basic analytes. (C) 2010 Wiley Periodicals, Inc.

During R/V Tangaroa cruise TAN0607 in 2006 heat flow probing for measurements of vertical fluid migration, sediment coring for methane concentrations, and additional seismic profiles were obtained across the ridge In a subsequent 2007 expedition, on R/V Sonne cruise SO191, a controlled source electromagnetic (CSEM) experiment was conducted along the same seismic. geochemical, and heat flow transect to reveal the electrical resistivity distribution CSEM data highlight a remarkable coincidence of anomalously high resistivity along the western, landward flank of the ridge which point to locally higher gas hydrate concentration above the high amplitude reflection band. Measured sediment temperature profiles, also along the western flank, consistently show non-linear and concave geothermal gradients typical of advective heat flow Geochemical data reveal elevated methane concentrations in surface sediments concomitant with a rapid decline in sulfate concentrations indicating elevated methane flux and oxidation of methane in conjunction with sulfate reduction at the landward ridge base Together, these data sets suggest that the western rim of Porangahau Ridge is a tectonically driven zone of rising fluids that transport methane and cause an upward inflection of the base of gas hydrate stability and the formation of locally enriched gas hydrate above the reflective zone (C) 2009 Elsevier B.V.

We present seismic data across the Porangahau Ridge on the outer accretionary wedge The data show high-amplitude reflections above the regional BSR level Based on polarity and reflection strength, we interpret these reflections as being caused by free gas We propose that the presence of gas above the regional level of BSRs indicates local upwarping of the base of gas hydrate stability caused by advective heatflow from upward migrating fluids, although we cannot entirely rule out alternative processes Simplified modelling of the increase of the thermal gradient associated with fluid flow suggests that funnelling of upward migrating fluids beneath low-permeability slope basins into the Porangahau Ridge would not lead to the pronounced thermal anomaly inferred from upwarping of the base of gas hydrate stability Focussing of fluid flow is predicted to take place deep in the accretionary wedge and/or the underthrust sediments. Above the high-amplitude reflections, sediment reflectivity is low. A lack of lateral continuity of reflections suggests that reflectivity is lost because of a destruction of sediment layering from deformation rather than gas-hydrate-related amplitude blanking Structural permeability from fracturing of sediments during deformation may facilitate fluid expulsion on the ridge A gap in the BSR in the southern part of the study area may be caused by a loss of gas during fluid expulsion We speculate that gaps in otherwise continuous BSRs that are observed beneath some thrusts on the Hikurangi Margin may be characteristic of other locations experiencing focussed fluid expulsion (C) 2009 Elsevier B.V.

TI Effects of magnetism and doping on the electron-phonon coupling in BaFe2As2 SO PHYSICAL REVIEW B LA English DT Article ID FERROPNICTIDES AB We calculate the effect of local magnetic moments on the electron-phonon coupling in doped BaFe2As2 using the density-functional perturbation theory. We show that the magnetism enhances the total electron-phonon coupling by similar to 50%, up to lambda <= 0.35, still not enough to explain the high critical temperature, but strong enough to have a non-negligible effect on superconductivity, for instance, by frustrating the coupling with spin fluctuations and inducing order-parameter nodes. The enhancement comes not from the phonon softening but mostly from a renormalization of the electron-phonon matrix elements. We also investigate, in the rigid band approximation, the effect of doping, and find that lambda versus doping does not mirror the behavior of the density of states; while the latter decreases upon electron doping, the former does not, and even increases slightly.

In this wavelength range video rate (60 fields/sec) spectrographic observations found the NUV and blue emissions to be predominantly N-2 (2PG). The negligible level of N-2 + (1NG) present in the spectrum is confirmed by observations of a co-aligned, narrowly filtered 427.8 nm imager and is in agreement with previous ground-based filtered photometer observations. The synthetic spectral fit to the observations indicates a characteristic energy of similar to 1.8 eV, in agreement with our other NUV observations. C1 [Heavner, M.

The trajectories of five CMEs are determined using LASCO/SOHO or SECCHI/STEREO data, and the associated soft X-ray (SXR) light curves are obtained from GOES 1-8 angstrom data. As the theoretical description of CME physics, the existing erupting flux-rope model is used in which an initial flux rope is driven out of equilibrium by the increasing poloidal magnetic flux Phi(p)(t) (poloidal "flux injection"). Mathematically, this is represented by d Phi(p)(t)/dt. For each CME, this function is adjusted to obtain the solution that best fits the observed height-time data. The resulting d Phi(p)(t)/dt is shown to be strongly constrained by the CME height data. This function and the attendant electromotive force (EMF) given by epsilon(t) = -(1/c)d Phi(p)(t)/dt constitute predictions of the theory for each CME trajectory. It is shown that the best-fit solutions fit the CME trajectories within 1%-2% of the CME height data and that the temporal profile of the predicted d Phi(p)(t)/dt is correlated with that of the associated X-ray light curve regardless of the flare duration. Specifically, we find that the observed duration of SXR emission Delta T-SXR is comparable to and scales with the predicted duration Delta T-p of poloidal flux injection, i.e.,Delta T-SXR similar or equal to Delta T-p. Neither the predicted d Phi(p)(t)/dt nor the input CME height data contain any information on X-ray data. Thus, the correlation is nontrivial, constituting evidence that poloidal flux injection is physically connected to flare energy release. It is suggested that this connection is provided by the EMF that produces electric fields to accelerate particles. C1 [Chen, James] USN, Div Plasma Phys, Res Lab, Washington, DC 20375 USA.

We find a 95% confidence interval for the pulse frequency derivative of (+0.7, +4.7) x 10(-14) Hz s(-1) and (-0.6, +3.8) x 10(-14) Hz s(-1) for the fundamental and second harmonics, respectively. The sinusoidal fractional amplitudes of the pulsations are the highest observed among AMXPs and can reach values of up to 27% (2.5-30 keV). The pulse arrival time residuals of the fundamental frequency follow a linear anti-correlation with the fractional amplitudes that suggests hot spot motion both in longitude and latitude over the surface of the neutron star. An anti-correlation between residuals and X-ray flux suggests an influence of the accretion rate on pulse phase and casts doubts on the interpretation of pulse frequency derivatives in terms of changes of spin rates and torques on the neutron star.

TI RESOLVING THE xi BOO BINARY WITH CHANDRA, AND REVEALING THE SPECTRAL TYPE DEPENDENCE OF THE CORONAL "FIP EFFECT" SO ASTROPHYSICAL JOURNAL LA English DT Article DE stars: coronae; stars: individual (xi Boo); stars: late-type; X-rays: stars ID SOLAR-TYPE STARS; EMISSION MEASURE DISTRIBUTIONS; INTERMEDIATE-ACTIVITY LEVELS; XMM-NEWTON VIEW; RAY SPECTROSCOPY; STELLAR CORONAE; ATOMIC DATABASE; NE/O ABUNDANCE; ACTIVE REGIONS; EQ-PEGASI AB On 2008 May 2, Chandra observed the X-ray spectrum of xi Boo (G8 V+K4 V), resolving the binary for the first time in X-rays and allowing the coronae of the two stars to be studied separately. With the contributions of xi Boo A and B to the system's total X-ray emission now observationally established (88.5% and 11.5%, respectively), consideration of mass loss measurements for GK dwarfs of various activity levels (including one for xi Boo) leads to the surprising conclusion that xi Boo B may dominate the wind from the binary, with. Boo A's wind being very weak despite its active corona. Emission measure (EM) distributions and coronal abundances are computed for both stars and compared with Chandra measurements of other moderately active stars with G8-K5 spectral types, all of which exhibit a narrow peak in EM near log T = 6.6, indicating that the coronal heating process in these stars has a strong preference for this temperature. As is the case for the Sun and many other stars, our sample of stars shows coronal abundance anomalies dependent on the first ionization potential (FIP) of the element. We see no dependence of the degree of "FIP effect" on activity, but there is a dependence on spectral type, a correlation that becomes more convincing when moderately active main-sequence stars with a broader range of spectral types are considered. This clear dependence of coronal abundances on spectral type weakens if the stellar sample is allowed to be contaminated by evolved stars, interacting binaries, or extremely active stars with log L(X) > 29, explaining why this correlation has not been recognized in the past.

TI FERMI OBSERVATIONS OF HIGH-ENERGY GAMMA-RAY EMISSION FROM GRB 090217A SO ASTROPHYSICAL JOURNAL LETTERS LA English DT Article DE gamma-ray burst: individual (GRB090217A) ID SYNCHROTRON SHOCK MODEL; LARGE-AREA TELESCOPE; SPECTRAL COMPONENT; BURST; PROMPT AB The Fermi observatory is advancing our knowledge of gamma-ray bursts (GRBs) through pioneering observations at high energies, covering more than seven decades in energy with the two on-board detectors, the Large Area Telescope (LAT) and the Gamma-ray Burst Monitor (GBM). Here, we report on the observation of the long GRB 090217A which triggered the GBM and has been detected by the LAT with a significance greater than 9 sigma. We present the GBM and LAT observations and on-ground analyses, including the time-resolved spectra and the study of the temporal profile from 8 keV up to similar to 1 GeV. All spectra are well reproduced by a Band model. We compare these observations to the first two LAT-detected, long bursts GRB 080825C and GRB 080916C. These bursts were found to have time-dependent spectra and exhibited a delayed onset of the high-energy emission, which are not observed in the case of GRB 090217A. We discuss some theoretical implications for the high-energy emission of GRBs. C1 [Ackermann, M.; Ajello, M.; Bechtol, K.; Berenji, B.; Blandford, R. D.; Borgland, A.

CA STAR Collaboration TI Higher Moments of Net Proton Multiplicity Distributions at RHIC SO PHYSICAL REVIEW LETTERS LA English DT Article ID QCD PHASE-DIAGRAM; CRITICAL-POINT; TRANSITION; COLLISIONS; MODEL AB 200 GeV corresponding to baryon chemical potentials (mu(B)) between 200 and 20 MeV. Our measurements of the products kappa sigma(2) and S sigma, which can be related to theoretical calculations sensitive to baryon number susceptibilities and long-range correlations, are constant as functions of collision centrality. We compare these products with results from lattice QCD and various models without a critical point and study the root s(NN) dependence of kappa sigma(2). From the measurements at the three beam energies, we find no evidence for a critical point in the QCD phase diagram for mu(B) below 200 MeV. C1 [Aggarwal, M. M.; Bhati, A. K.; Pruthi, N.

A prior history of mastectomy is felt to be a contraindication. Case presentation: A patient with recurrent breast cancer in her skin flap was discovered to have positive axillary sentinel nodes by sentinel lymph node biopsy five years after mastectomy for ductal carcinoma in situ. Conclusion: A prior history of mastectomy may not be an absolute contraindication to sentinel lymph node biopsy.

CA STAR Collaboration TI Three-Particle Coincidence of the Long Range Pseudorapidity Correlation in High Energy Nucleus-Nucleus Collisions SO PHYSICAL REVIEW LETTERS LA English DT Article ID GLASMA FLUX TUBES AB We report the first three-particle coincidence measurement in pseudorapidity (Delta eta) between a high transverse momentum (p(perpendicular to)) trigger particle and two lower p(perpendicular to) associated particles within azimuth |Delta phi| < 0.7 in root s(NN) = 200 GeV d + Au and Au + Au collisions. Charge ordering properties are exploited to separate the jetlike component and the ridge (long range Delta eta correlation). The results indicate that the correlation of ridge particles are uniform not only with respect to the trigger particle but also between themselves event by event in our measured Delta eta. In addition, the production of the ridge appears to be uncorrelated to the presence of the narrow jetlike component. C1 [Abelev, B. I.; Barannikova, O.; Betts, R. R.; Garcia-Solis, E. J.; Hofman, D.

TI Nonlinear Rossby waves off California SO GEOPHYSICAL RESEARCH LETTERS LA English DT Article AB A new interpretation of SSH anomalies propagating in the California Current System as weakly nonlinear Rossby waves (RWs) is suggested. Satellite altimetry and float data were used to extract annual and semi-annual components of RWs from a multi-scale altimetry signal and estimate their kinematic characteristics. Different propagation regimes for the waves were identified by propagation speed, wave steepness and length of spatial phase coherence (SPC). A transition from a SSH field dominated by waves to a turbulent-like field was detected in the saturation regime. The recurrence period for wave behavior was estimated as about 105-120 (195-210) days for the semiannual (annual) component. The propagation speed and length of SPC decreased when wave steepness increased, and westward propagation halted during the saturation regime. Citation: Ivanov, L. M., C. A. Collins, T. M.

Contact angle goniometry, visible absorption spectroscopy, and atomic force microscopy were used to assess the formation, desorption, and photopolymerization of SAMs of diacetylenic alkylphosphonicl acids (CH(3)(CH(2))(n) -C equivalent to C-C equivalent to C- (CH(2))(m)PO(OH)(2); (m, n) = (3, 11), (6, 8), and (9, 5)). As with GaN substrates (Ito, T.; Forman, S. M.; Cao, C.; Li, E.; Eddy, C. R., Jr.; Mastro, M. A.; Holm, R. T.; Henry, R. L.; Hohn, K.; Edgar, J. H. Langmuir 2008, 24, 6630-6635), alkylphosphonic acids formed SAMs on UV/O(3)-treated AlGaN substrates from their toluene solutions in contrast to other primary substituted hydrocarbons with a terminal -COOH, -NH(2), -OH, or -SH group, Diacetylenic alkylphosphonate SAMs on group-Ill nitrides could be polymerized by UV irradiation (254 nm), as indicated by the appearance of a visible absorption band around 640 nm and also by their significantly reduced desorption from the surface in a 0.1 M aqueous NaOH solution. A longer UV irradiation time was required to maximize the photopolymerization of a SAM having a diacetylene group close to the terminal phosphonatc moiety, probably because of the hindrance of the topochemical polymerization due to the limited flexibility of the cross-linking moieties on an atomically rough substrate surface.

TI Effect of the Crosslink Functionality on the Mechanical Properties of Crosslinked 1,2,3-Triazole Polymers as Potential Binders for Rocket Propellants SO JOURNAL OF APPLIED POLYMER SCIENCE LA English DT Article DE crosslinking; mechanical properties; modulus; polyurethanes; strain ID AZIDE-ALKYNE CYCLOADDITION; ELASTOMERIC PROPERTIES; JUNCTION FUNCTIONALITY; CLICK CHEMISTRY; MODEL NETWORKS; DEPENDENCE; HYDROGELS; DENSITY; SCIENCE; CHAINS AB The mechanical properties of crosslinked polymers depend on their structural features, one of which is the functionality of the crosslinks in a polymer network. To study the effect of crosslink functionality (Phi) on the mechanical properties of 1,2,3-triazole polymers for potential application as rocket propellant binders, crosslinkers with different Phi's (3, 4, 6, 16, 32, and 64) were used in the polymerization. As the percentage of acetylenic groups provided by crosslinker was kept constant and the functionality of the crosslinker increased, the resulting polymer showed a higher modulus but a lower strain. Compared to traditional polyurethane binders, 1,2,3-triazole polymers showed comparable mechanical properties, although the stress and modulus tended to be lower and the strain capability tended to be greater for the triazole-linked rubbers.

TI Design and characterization of terahertz-absorbing nano-laminates of dielectric and metal thin films SO OPTICS EXPRESS LA English DT Article AB A terahertz-absorbing thin-film stack, containing a dielectric Bragg reflector and a thin chromium metal film, was fabricated on a silicon substrate for applications in bi-material terahertz (THz) sensors. The Bragg reflector is to be used for optical readout of sensor deformation under THz illumination. The THz absorption characteristics of the thin-film composite were measured using Fourier transform infrared spectroscopy. The absorption of the structure was calculated both analytically and by finite element modeling and the two approaches agreed well. Finite element modeling provides a convenient way to extract the amount of power dissipation in each layer and is used to quantify the THz absorption in the multi-layer stack. The calculation and the model were verified by experimentally characterizing the multi-layer stack in the 3-5 THz range. The measured and simulated absorption characteristics show a reasonably good agreement. It was found that the composite film absorbed about 20% of the incident THz power. The model was used to optimize the thickness of the chromium film for achieving high THz absorption and found that about 50% absorption can be achieved when film thickness is around 9 nm.

TI Double Negative (CD3(+)4(-)8(-)) TCR alpha beta Splenic Cells from Young NOD Mice Provide Long-Lasting Protection against Type 1 Diabetes SO PLOS ONE LA English DT Article ID REGULATORY T-CELLS; INVARIANT NKT CELLS; VERSUS-HOST-DISEASE; GAMMA-DELTA; IN-VIVO; SUPPRESSOR CELLS; INTERFERON-GAMMA; CUTTING EDGE; ANTIGEN; MOUSE AB Background: Double negative CD3(+)4(-)8(-) TCR alpha beta splenic cells (DNCD3) can suppress the immune responses to allo and xenografts, infectious agents, tumors, and some autoimmune disorders. However, little is known about their role in autoimmune diabetes, a disease characterized by the reduction of insulin production subsequent to destruction of pancreatic beta-cells by a polyclonal population of self-reactive T-cells. Herein, we analyzed the function and phenotype of DNCD3 splenic cells in young NOD mice predisposed to several autoimmune disorders among which, the human-like autoimmune diabetes. Methodology/Principal Findings: DNCD3 splenic cells from young NOD mice (1) provided long-lasting protection against diabetes transfer in NOD/Scid immunodeficient mice, (2) proliferated and differentiated in the spleen and pancreas of NOD/Scid mice and pre-diabetic NOD mice into IL-10-secreting T-R-1 like cells in a Th2-like environment, and (3) their anti-diabetogenic phenotype is CD3(+)(CD4(-)CD8(-))CD28(+)CD69(+)CD25(low) Foxp3(-) iCTLA-4(-)TCR alpha beta(+) with a predominant V beta 13 gene usage. Conclusions/Significance: These findings delineate a new T regulatory component in autoimmune diabetes apart from that of NKT and CD4(+)CD25(high) Foxp3(+)T-regulatory cells. DNCD3 splenic cells could be potentially manipulated towards the development of autologous cell therapies in autoimmune diabetes. C1 [Duncan, Beverly] NCI, NIH, Bethesda, MD 20892 USA.

The resulting dot morphologies and their configurational uniformity are studied using cross sectional scanning tunneling microscopy and atomic force microscopy. Combining photoluminescence measurements with structural characterization allows interpretation of the ensemble photoluminescence spectrum. Bright spectra for the three-dimensional structures suggest an improved method for combining lithographic nucleation sites with self-assembled dot growth. These techniques can be applied to lithographic templates to fabricate complex quantum dot networks.

TI Demonstration of concept for fabrication of lunar physical assets utilizing lunar regolith simulant and a geothermite reaction SO ACTA ASTRONAUTICA LA English DT Article DE ISRU; Moon; Regolith; SHS; Dome; Habitat AB NASA's anticipated return to the Moon by 2020 and subsequent establishment of a lunar base will necessitate the development of methods to utilize lunar resources for various construction and resource extraction applications. In this study the design of a lunar physical asset utilizing in-situ resources available at the lunar surface was examined. The design incorporated a voussoir dome type of architecture that has been in use for centuries on Earth. Production of the desired dome elements was accomplished by initiating a geothermite reaction in a mixture of lunar regolith simulant and aluminum powder. Shaping of voussoir elements was accomplished during the reaction using a custom fabricated silica-slip crucible to contain the geothermite reactant mixture. The product of the reaction retained the shape of the crucible. (C) 2009 Elsevier Ltd. All rights reserved.
