Previous theoretical efforts have pointed out that this deficiency can be overcome using an along-track multichannel SAR (MSAR), but lack an experimental foundation. In this paper we conduct in-depth sensitivity studies that characterize and demonstrate the robustness of an MSAR system for scene motion characterization. These include novel experimental studies that build on our previous work in MSAR emulation. Of significance, to our knowledge this is the first experimental verification of removing motion distortions in shoaling ocean waves using such an MSAR system. We also introduce a new processing mode for MSAR systems called SAVSAR (subaperture velocity SAR), which affords us a much wider range of options in adjusting the spatial and temporal resolution capabilities of MSAR imaging. The insights gained in this paper provide guidance on the choice of suitable configurations and processing methods for scene motion estimation using airborne MSAR systems.

The operational background is analyzed with respect to the potential use of these systems by field officers. An analysis for operational micro and picosatellite characteristics is executed, and a brief outlook on the vulnerabilities of those for Low Earth Orbits is given. Moreover, a real scenario has been implemented, and the obtained computational results provide useful insight into how these space systems can be used for maritime security operations. Particular reference is given to the state-of-the-art status of propulsion systems capable of enhancing the lifetime of the satellites. Similarly, a literature survey has been conducted collecting all available picosatellites in orbit today that deal with maritime security applications. The study also explores the application of Lambdasat picosatellite (currently in orbit) to demonstrate the capability of exchanging alert messages between ground stations in Greece and in the US and vessels in the middle of the ocean. With these experiments we will demonstrate the ability magnitude of a picosatellite to support maritime operations.

Acoust. Soc. Am. 134, 3347-3358 (2013)] for measurements acquired during the 2009 Philippine Sea experiment and associated Monte Carlo computations. The predictions here utilize the theory of Munk and Zachariasen [J. Acoust. Soc. Am. 59, 818-838 (1976)]. The scattering mechanism is the Garrett-Munk internal wave spectrum scaled by metrics based on measured environmental profiles. The transmitter was at 1000m depth and the receivers at nominal range 107 km and depths 600-1600 m. The signal was a broadband m-sequence centered at 284 Hz. Four classes of propagation paths are examined: the first class has a single upper turning point at about 60m depth; the second and third classes each have two upper turning points at roughly 250 m; the fourth class has three upper turning points at about 450 m. Log-amplitude variance for all paths is predicted to be 0.04-0.09, well within the regime of validity of either Born or Rytov scattering. The predictions are roughly consistent with the measured and Monte Carlo log-amplitude variances, although biased slightly low. Paths turning in the extreme upper ocean (near the mixed layer) seem to incorporate additional scattering mechanisms not included in the original theory. (C) 2015 Acoustical Society of America.

TI Underwater sound transmission through arrays of disk cavities in a soft elastic medium SO JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA LA English DT Article ID ALBERICH ANECHOIC COATINGS; ABSORPTION MECHANISMS; WATERBORNE SOUND; SCATTERING; WAVE; BUBBLES; ULTRASOUND; OSCILLATIONS; RESONANCE; SOLIDS AB Scattering from a cavity in a soft elastic medium, such as silicone rubber, resembles scattering from an underwater bubble in that low-frequency monopole resonance is obtainable in both cases. Arrays of cavities can therefore be used to reduce underwater sound transmission using thin layers and low void fractions. This article examines the role of cavity shape by microfabricating arrays of disk-shaped air cavities into single and multiple layers of polydimethylsiloxane. Comparison is made with the case of equivalent volume cylinders which approximate spheres. Measurements of ultrasonic underwater sound transmission are compared with finite element modeling predictions. The disks provide a deeper transmission minimum at a lower frequency owing to the drum-type breathing resonance. The resonance of a single disk cavity in an unbounded medium is also calculated and compared with a derived estimate of the natural frequency of the drum mode. Variation of transmission is determined as a function of disk tilt angle, lattice constant, and layer thickness. A modeled transmission loss of 18 dB can be obtained at a wavelength about 20 times the three-layer thickness, and thinner results (wavelength/thickness similar to 240) are possible for the same loss with a single layer depending on allowable hydrostatic pressure.

TI Using the Discrete Event System Specification to model Quantum Key Distribution system components SO JOURNAL OF DEFENSE MODELING AND SIMULATION-APPLICATIONS METHODOLOGY TECHNOLOGY-JDMS LA English DT Article DE Conceptual modeling; Discrete Event Simulation; Discrete Event System Specification; modeling and simulation; Quantum Key Distribution ID SIMULATION; DEVS AB In this paper, we present modeling a Quantum Key Distribution (QKD) system with its components using the Discrete Event System Specification (DEVS) formalism. The DEVS formalism assures the developed component models are composable and exhibit well-defined temporal behavior independent of the simulation environment. These attributes enable users to assemble a valid simulation using any collection of compatible components to represent complete QKD system architectures. To illustrate the approach, we introduce a prototypical "prepare and measure'' QKD system, decompose one of its subsystems, and present the detailed modeling of the subsystem using the DEVS formalism. The developed models are provably composable and exhibit behavior suitable for the intended analytic purpose, thus improving the validity of the simulation. Finally, we examine issues identified during the verification of the conceptual DEVS model and discuss the impact of these findings on implementing a hybrid QKD simulation framework.

TI Reduction Expansion Synthesis as Strategy to Control Nitrogen Doping Level and Surface Area in Graphene SO MATERIALS LA English DT Article DE reduction-expansion-synthesis; nitrogen-doped graphene ID LITHIUM-ION BATTERIES; DOPED MONOLAYER GRAPHENE; GRAPHITE OXIDE; ANODE MATERIALS; UREA; SHEETS; SUPERCAPACITORS; FABRICATION; SONICATION; NANOSHEETS AB Graphene sheets doped with nitrogen were produced by the reduction-expansion (RES) method utilizing graphite oxide (GO) and urea as precursor materials. The simultaneous graphene generation and nitrogen insertion reactions are based on the fact that urea decomposes upon heating to release reducing gases. The volatile byproducts perform two primary functions: (i) promoting the reduction of the GO and (ii) providing the nitrogen to be inserted in situ as the graphene structure is created. Samples with diverse urea/GO mass ratios were treated at 800 degrees C in inert atmosphere to generate graphene with diverse microstructural characteristics and levels of nitrogen doping. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to study the microstructural features of the products. The effects of doping on the samples structure and surface area were studied by X-ray diffraction (XRD), Raman Spectroscopy, and Brunauer Emmet Teller (BET). The GO and urea decomposition-reduction process as well as nitrogen-doped graphene stability were studied by thermogravimetric analysis (TGA) coupled with mass spectroscopy (MS) analysis of the evolved gases. Results show that the proposed method offers a high level of control over the amount of nitrogen inserted in the graphene and may be used alternatively to control its surface area. To demonstrate the practical relevance of these findings, as-produced samples were used as electrodes in supercapacitor and battery devices and compared with conventional, thermally exfoliated graphene.

A brief overview of bond-order potentials is provided which focuses on the reactive empirical bond-order (REBO) potential for hydrocarbons (Brenner et al 2002 J. Phys.: Condens. Matter 14 783) and the large number of useful potentials it has spawned. Two specific extensions of the REBO potential that make use of its formalism are discussed. First, the 2B-SiCH potential (Schall and Harrison 2013 J. Phys. Chem. C 117 1323) makes the appropriate changes to the hydrocarbon REBO potential so that three atom types, Si, C, and H, can be modeled. Second, we recently added the electronegative element O, along with the associated charge terms, to the adaptive intermolecular REBO (AIREBO) potential (Stuart et al 2000 J. Chem. Phys. 112 6472). The resulting qAIREBO potential (Knippenberg et al 2012 J. Chem. Phys. 136 164701) makes use of the bond-order potential/split-charge (BOP/SQE) equilibration method (Mikulski et al 2009 J. Chem. Phys. 131 241105) and the Lagrangian approach to charge dynamics (Rick et al 1994 J. Chem. Phys. 101 6141). The integration of these two techniques allows for atomic charges to evolve with time during MD simulations: as a result, chemical reactions can be modeled in C-, O-, and H-containing systems. The usefulness of the 2B-SiCH potential for tribological investigations is demonstrated in molecular dynamics (MD) simulations of axisymmetric tips composed of Si and SiC placed in sliding contact with diamond(1 1 1) surfaces with varying amounts of hydrogen termination. The qAIREBO potential is used to investigate confinement of sub-monolayer coverages of water between nanostructured surfaces.

To better understand the reaction dynamics of these ionic liquid fuels, this study reports the results of molecular dynamics simulations performed for two predicted intermediate compounds in DCA-based ionic liquids/nitric acid (HNO3) combustion, i.e. protonated DCA (DCAH) and nitro-dicyanamide-carbonyl (NDC). Calculations were performed using a ReaxFF reactive force field. Single component simulations show that neat NDC undergo exothermic decomposition and ignition. Simulations with HNO3 were performed at both a low (0.25 g ml(-1)) and high (1.00 g ml(-1)) densities, to investigate the reaction in a dense vapor and liquid phase, respectively. Both DCAH and NDC react hypergolically with HNO3, and increased density led to shorter times for the onset of thermal runaway. Contrary to a proposed mechanism for DCA combustion, neither DCAH nor NDC are converted to 1,5-Dinitrobiuret (DNB) before thermal runaway. Details of reaction pathways for these processes are discussed. C1 [Weismiller, Michael R.; Junkermeier, Chad E.; Russo, Michael F., Jr.; van Duin, Adri C.

TI Lagrangian vortices in developing tropical cyclones SO QUARTERLY JOURNAL OF THE ROYAL METEOROLOGICAL SOCIETY LA English DT Article DE vortex identification; Lagrangian coherent structures; tropical cyclogenesis ID WAVE CRITICAL LAYER; 2-DIMENSIONAL TURBULENCE; COHERENT STRUCTURES; VELOCITY-FIELDS; 2D TURBULENCE; TRANSPORT; VORTEX; CYCLOGENESIS; CRITERION; SYSTEMS AB Tracking pre-genesis tropical cyclones is important for earlier detection of developing systems as well as targeting potential locations for dropsondes in field experiments. The use of a reference frame moving with the disturbance gives a more accurate depiction of streamlines and closed circulation than the Earth-relative frame. However, identification of recirculating regions does not require a choice of reference frame when marked by the Galilean invariant Eulerian Okubo-Weiss (OW) parameter. While the Eulerian OW parameter is generally effective at identifying vortex cores at a given place and a given time, it has its limitations in weak disturbances and in time-dependent flows. Integrating the eigenvalue of the velocity gradient tensor along particle trajectories provides a time-smoothing of the Eulerian OW parameter, and provides earlier detection with fewer false alarms. We refer to this integration along trajectories as the Lagrangian OW parameter. When mapped to a horizontal grid it becomes a Lagrangian OW field. The Lagrangian OW field has advantages over the Eulerian OW field in the detail of additional flow structures that it identifies. The Lagrangian OW field shows the Lagrangian boundaries that are present as a disturbance develops from an easterly wave, and a shear sheath that forms when a disturbance becomes self-sustaining, typically at tropical storm strength. Since all of these structures are Lagrangian, they are advected with the flow field, and display the continuous evolution of coherent flow features as the fluid evolves. Examples of the use of the Lagrangian OW field are given for ECMWF forecast data from the 2014 Atlantic hurricane season. All of the Lagrangian coherent structures that can be identified by this field are shown for developing disturbances and mature cyclones. The Lagrangian OW field also shows additional details of vortex mergers, and is used to identify a stable crystal lattice configuration in which vorticity does not aggregate.

TI The benefits of correlated observation errors for small scales SO QUARTERLY JOURNAL OF THE ROYAL METEOROLOGICAL SOCIETY LA English DT Article DE correlated observation error; high-resolution analysis; observation-error covariance; data assimilation ID DATA ASSIMILATION; OBSERVATION DENSITY; RESOLUTION AB In operational data assimilation, observation errors are generally assumed to be uncorrelated, though some observations, such as satellite data, have correlated errors. We show that, if observation-error correlations are correctly accounted for, an observing instrument with spatially correlated errors is better able to resolve small scales than an instrument with the same error variance and uncorrelated errors. We explore the disadvantages of falsely assuming uncorrelated observation errors, investigating two methods of compensating for such mis-specification by either observation-error inflation or data thinning. We identify scenarios in which correctly specifying the covariance reduces small-scale error by over 99%. C1 [Rainwater, Sabrina] Naval Res Lab, Natl Res Council, Monterey, CA 93943 USA.

TI LOCAL INTERSTELLAR MEDIUM: SIX YEARS OF DIRECT SAMPLING BY IBEX SO ASTROPHYSICAL JOURNAL SUPPLEMENT SERIES LA English DT Article DE interplanetary medium; ISM: general; local interstellar matter; Sun: heliosphere ID BOUNDARY-EXPLORER OBSERVATIONS; LO OBSERVATIONS; FLOW PARAMETERS; SOLAR-SYSTEM; PHYSICAL-PROPERTIES; ABUNDANCE RATIO; NEUTRAL HELIUM; HYDROGEN WALL; STELLAR-WIND; GAS-FLOW AB The Interstellar Boundary Explorer (IBEX) has been directly observing neutral atoms from the local interstellar medium for the last six years (2009-2014). This paper ties together the 14 studies in this Astrophysical Journal Supplement Series Special Issue, which collectively describe the IBEX interstellar neutral results from this epoch and provide a number of other relevant theoretical and observational results. Interstellar neutrals interact with each other and with the ionized portion of the interstellar population in the "pristine" interstellar medium ahead of the heliosphere. Then, in the heliosphere's close vicinity, the interstellar medium begins to interact with escaping heliospheric neutrals. In this study, we compare the results from two major analysis approaches led by IBEX groups in New Hampshire and Warsaw. We also directly address the question of the distance upstream to the pristine interstellar medium and adjust both sets of results to a common distance of similar to 1000 AU. The two analysis approaches are quite different, but yield fully consistent measurements of the interstellar He flow properties, further validating our findings. While detailed error bars are given for both approaches, we recommend that for most purposes, the community use "working values" of similar to 25.4 km s(-1), similar to 75 degrees.7 ecliptic inflow longitude, similar to-5 degrees.1 ecliptic inflow latitude, and similar to 7500 K temperature at similar to 1000 AU upstream. Finally, we briefly address future opportunities for even better interstellar neutral observations to be provided by the Interstellar Mapping and Acceleration Probe mission, which was recommended as the next major Heliophysics mission by the NRC's 2013 Decadal Survey.

TI EXPLORING THE POSSIBILITY OF O AND Ne CONTAMINATION IN ULYSSES OBSERVATIONS OF INTERSTELLAR HELIUM SO ASTROPHYSICAL JOURNAL SUPPLEMENT SERIES LA English DT Article DE ISM: atoms; Sun: heliosphere ID IBEX-LO OBSERVATIONS; INTERPLANETARY HYDROGEN; FLOW PARAMETERS; ABUNDANCE RATIO; NEUTRAL HELIUM; SOLAR-SYSTEM; BOW SHOCK; HELIOSPHERE; TEMPERATURE; OXYGEN AB We explore the possibility that interstellar O and Ne may be contributing to the particle signal from the GAS instrument on Ulysses, which is generally assumed to be entirely He. Motivating this study is the recognition that an interstellar temperature higher than any previously estimated from Ulysses data could potentially resolve a discrepancy between Ulysses He measurements and those from the Interstellar Boundary Explorer (IBEX). Contamination by O and Ne could lead to Ulysses temperature measurements that are too low. We estimate the degree of O and Ne contamination necessary to increase the inferred Ulysses temperature to 8500 K, which would be consistent with both the Ulysses and IBEX data given the same interstellar flow speed. We find that producing the desired effect requires a heavy element contamination level of similar to 9% of the total Ulysses/GAS signal. However, this degree of heavy element contribution is about an order of magnitude higher than expected based on our best estimates of detection efficiencies, ISM abundances, and heliospheric survival probabilities, making it unlikely that heavy element contamination is significantly affecting temperatures derived from Ulysses data.

TI Observation of 27day solar cycles in the production and mesospheric descent of EPP-produced NO SO JOURNAL OF GEOPHYSICAL RESEARCH-SPACE PHYSICS LA English DT Article DE energetic particle precipitation (EPP); mesosphere; nitric oxide; geomagnetic index; middle atmosphere; mesosphere-lower thermosphere (MLT) ID UNIVERSAL TIME VARIATIONS; NITRIC-OXIDE; LOWER THERMOSPHERE; GEOMAGNETIC-ACTIVITY; MIDDLE ATMOSPHERE; ICE EXPERIMENT; PROTON EVENTS; STRATOSPHERE; OCCULTATION; LATITUDES AB Nitric oxide (NO) is produced by energetic particle precipitation (EPP) in the mesosphere-lower thermosphere (MLT) region, and during the polar winter, NO can descend to stratospheric altitudes where it destroys ozone. In this paper, we study the general scenario, as opposed to a case study, of NO production in the thermosphere due to energetic particles in the auroral region. We first investigate the relationship between NO production and two geomagnetic indices. The analysis indicates that the auroral electrojet index is a more suitable proxy for EPP-produced NO than the typically used midlatitude Ap index. In order to study the production and downward transport of NO from the lower thermosphere to the mesosphere, we perform superposed epoch analyses on NO observations made by the Solar Occultation For Ice Experiment instrument on board the Aeronomy of Ice in the Mesosphere satellite. The epoch analysis clearly shows the impact of the 27day solar cycle on NO production. The effect is observed down to an altitude range of about 50km to 65km, depending on the hemisphere and the occurrence of stratospheric warmings. Initially, a rapid downward transport is noted during the first 10days after EPP onset to an altitude of about 80-85km, which is then followed by a slower downward transport of approximately 1-1.2km/d to lower mesospheric altitudes in the order of 30days.

Such accumulations of material play an important role in a variety of applications, from biology to pollution mitigation. Identifying where clusters will form can aid in locating, for example, hotspots of biological activity or regions of high pollutant concentration. Here cluster strength is introduced as a new metric for defining clusters when all particle positions are known. To diagnose regions likely to contain clusters without the need to integrate millions of particle trajectories, we propose to use dilation, which quantifies area changes of Lagrangian patches. Material deformation is decomposed into dilation and area-preserving stretch processes to refine previous approaches based on finite-time Lyapunov exponents (FTLE) by splitting the FTLE into fundamental kinematic properties. The concepts are developed theoretically and illustrated in the context of a state-of-the-art data-assimilating predictive ocean model of the Gulf of Mexico. Regions of dilation less than one are shown to be much more likely (6 times more likely in the given example) to be visited by particles than those of dilation greater than one. While the relationship is nonlinear, dilation and cluster strength exhibit a fairly good correlation. In contrast, both stretch and Eulerian divergence are found to be uncorrelated with cluster strength. Thus, dilation maps can be used as guides for identifying cluster locations, while saving some of the computational cost of trajectory integrations. C1 [Huntley, Helga S.; Lipphardt, B.

TI Southern Bay of Bengal currents and salinity intrusions during the northeast monsoon SO JOURNAL OF GEOPHYSICAL RESEARCH-OCEANS LA English DT Article ID MADDEN-JULIAN OSCILLATION; INDIA COASTAL CURRENT; MIXED-LAYER; SOUTHWEST MONSOON; TROPICAL PACIFIC; OCEAN; CIRCULATION; PREDICTION; DYNAMICS; DRIFTERS AB Shipboard velocity and hydrographic profiles collected in December 2013 along with drifter observations, satellite altimetry, global ocean nowcast/forecast products, and coupled model simulations were used to examine the circulation in the southern Bay of Bengal as part of ongoing international research efforts in the region. The observations captured the southward flowing East India Coastal Current (EICC) off southeast India and east of Sri Lanka. The EICC was approximately 100 km wide, with speeds exceeding 1 m s(-1) in the upper 75 m. East of the EICC, a subsurface-intensified 300 km-wide, northward current was observed, with maximum speeds as high as 1 m s(-1) between 50 m and 75 m. The EICC moved low-salinity water out of the bay and the subsurface northward flow carried high-salinity water into the bay during typical northeast monsoon conditions during a time period when the central equatorial Indian Ocean was experiencing a westerly wind burst related to the Madden-Julian Oscillation (MJO) event. While the northward subsurface high-salinity flow has previously been observed during the southwest monsoon, it was observed during the northeast monsoon. The observations are consistent with northward high-salinity subsurface flow in numerical model solutions. The analysis suggests that direct forcing along the equator may play a significant role for high-salinity intrusions east of Sri Lanka. C1 [Wijesekera, H. W.; Jensen, T. G.; Jarosz, E.; Teague, W.

The measured VSFs are consistent with concurrent measurements of total scattering coefficients by the ac-meters and angular scattering at 100, 125, and 1508 by the ECO-VSF sensor and at 1408 by the HydroScat-6 sensor. The inferred backscattering coefficients by the VSPs correlate strongly with the absorption coefficients measured for the colored dissolved organic matter, indicating that the dissolved portion of particles do scatter light. In the coastal waters that we studied, the backscattering by VSPs dominate over larger particles (of sizes >0.2 mu m), accounting for 40-80% of total backscattering at 532 nm, while only account for <5% of total scattering.

This process relies on subjecting masked diamond films to a controlled oxygen atmosphere at temperatures of 700-800 degrees C to controllably etch both vertically through the film and laterally underneath the mask SiO2, SiNx, and Al2O3 films constitute viable mask materials for this process, provided that the underlying diamond film is fully outgassed before mask deposition and diamond etching. As expected, etching occurred more rapidly at higher temperatures. The etch rate was higher in the lateral direction than the vertical direction, which has been attributed to accelerated etching along disordered grain boundaries and the underlying nucleation layer. Similar activation energies (136-140 kj/mol) were obtained for both lateral and vertical etching from 700 to 800 degrees C. Using the dry etch process developed in this research, diamond films can be removed from exposed features and undercut masked regions at a controlled rate, as indicated by microscopy and Raman spectroscopy.

At the lowest temperatures, the increases in C and Q(-1) are consistent with an increased density of two-level systems (TLS). The light-induced increase in C persists to room temperature. Neither the sound velocity nor shear modulus change with light soaking indicating that the Debye specific heat is unchanged which suggests that light soaking creates localized vibrational modes in addition to TLS. The increase can be reversibly added and removed by light soaking and annealing, respectively, suggesting that it is related to the Staebler-Wronski effect (SWE), even in a-Si without H, and involves a reversible nanoscale structural rearrangement that is facilitated by, but does not require, H to occur.

In this study, we compare the normalized water-leaving radiance (nLw) products generated by the Naval Research Laboratory Automated Processing System (APS) with those produced by the stand-alone software package, the GOCI Data Processing System (GDPS), developed by the Korean Ocean Research & Development Institute (KORDI). Both results are then compared to the nLw measured by the above water radiometer at the Ieodo site. This above-water radiometer is part of the Aerosol Robotic NETwork (AeroNET). The results indicate that the APS and GDPS processed nLw correlates well within the same image slot where the coefficient of determination (r(2)) is higher than 0.84 for all the bands from 412 nm to 745 nm. The agreement between APS and the AeroNET data is higher when compared to the GDPS results. The Root-Mean-Squared-Error (RMSE) between AeroNET and APS data ranges from 0.24 [mW/(cm(2)sr mu m)] at 555 nm to 0.52 [mW/(cm(2)sr mu m)] at 412 nm while RMSE between AeroNET and GDPS data ranges from 0.47 [mW/(cm(2)sr mu m)] at 443 nm to 0.69 [mW/(cm(2)sr mu m)] at 490 nm.

The codes include the single-Gaussian DEM, a bi-Gaussian DEM, a fixed-Gaussian DEM, a linear spline DEM, the spatial-synthesis DEM, the Monte-Carlo Markov Chain DEM, the regularized DEM inversion, the Hinode/X-Ray Telescope (XRT) method, a polynomial spline DEM, an EVE+GOES, and an EVE+RHESSI method. Averaging the results from all 11 DEM methods, we find the following accuracies in the inversion of physical parameters: the EM-weighted temperature , the peak emission measure , the total emission measure , and the multi-thermal energies . We find that the AIA spatial-synthesis, the EVE+GOES, and the EVE+RHESSI method yield the most accurate results.

Fabricated diabolo optical antenna arrays were characterized by measuring the transmittance and reflectance with a microscope-coupled FTIR spectrometer. It was found experimentally that reducing the waist width significantly shifts the resonance to longer wavelength and narrowing the waist of the antennas is more effective than increasing the period of the array for tuning the resonance wavelength. Also it is found that the magnetic field enhancement near the antenna waist is correlated to the shift of the resonance wavelength. (C) 2015 Author(s).

Suppression of interband Auger decay, such as biexciton Auger recombination, has been achieved with the design of heterostructured core shell QDs. Auger-like processes are also believed to be responsible for rapid intraband hot-electron cooling in QDs. However, the simultaneous effect of shell growth on interband Auger recombination and intraband hot-electron cooling has not been addressed. Here we investigate how the growth of a CdS shell affects these two relaxation processes in CdSe/CdS core shell QDs. Using a combination of ultrafast pump push probe spectroscopy on the QD ensemble and analysis of the photon statistics from single QDs, we find that Auger losses in the biexciton state are suppressed with increasing shell thickness, while hot-electron cooling remains unaffected. Calculations conducted within an eight-band k.p model confirm the experimental dependence of the biexciton Auger decay on the shell thickness, and provide insights into the factors determining the cooling rate of hot carriers.

This article provides a review of existing studies evaluating the impacts of data from the TAO/TRITON array and other components of the Tropical Pacific Observing System (TPOS) on current ocean DA systems used for a variety of operational and research applications. It can be considered as background information that can guide the evaluation exercise of TPOS. Temperature data from TAO/TRITON array are assimilated in most ocean DA systems which cover the tropical Pacific in order to constrain the ocean heat content, stratification, and circulation. It is shown that the impacts of observation data depend considerably on the system and application. The presence of model error often makes the results difficult to interpret. Nevertheless there is consensus that the data from TAO/TRITON generally have positive impacts complementary to Argo floats. In the equatorial Pacific, the impacts are generally around the same level or larger than those of Argo. We therefore conclude that, with the current configuration of TPOS, the loss of the TAO/TRITON data is having a significant detrimental impact on many applications based on ocean DA systems. This conclusion needs to be kept under review because the equatorial coverage by Argo is expected to improve in the future.

Here we report on the analysis of a deep Herschel/PACS observation of an extremely high-J CO transition (40-39) in the Seyfert 2 galaxy NGC 1068. The line was not detected, with a derived 3 sigma upper limit of 2 x 10(-17) W m(-2). We apply an XDR model in order to investigate whether the upper limit constrains the properties of a molecular torus in NGC 1068. The XDR model predicts the CO spectral line energy distributions for various gas densities and illuminating X-ray fluxes. In our model, the CO(40-39) upper limit is matched by gas with densities of similar to 10(6)-10(7) cm(-3), located at 1.6-5 pc from the AGN, with column densities of at least 1025 cm (2). At such high column densities, however, dust absorbs most of the CO(40-39) line emission at lambda = 65.69 mu m. Therefore, even if NGC 1068 has a molecular torus that radiates in the CO(40-39) line, the dust can attenuate the line emission to below the PACS detection limit. The upper limit is thus consistent with the existence of a molecular torus in NGC 1068. In general, we expect that the CO(40-39) is observable in only a few AGN nuclei (if at all), because of the required high gas column density, and absorption by dust. C1 [Janssen, A.

TI Spanning Strong to Weak Normal Mode Coupling between Vibrational and Fabry-Perot Cavity Modes through Tuning of Vibrational Absorption Strength SO ACS PHOTONICS LA English DT Article DE quantum optical chemistry; vacuum Rabi splitting; strong coupling; infrared spectroscopy; optical cavity; vibrational coupling ID SINGLE QUANTUM-DOT; SEMICONDUCTOR MICROCAVITIES; POLAR-SOLVENTS; VACUUM-FIELD; RELAXATION; EXCITONS; SYSTEM; STATES AB Designing coupled vibrational-cavity polariton systems to modify chemical reaction rates and paths requires an understanding of how this coupling depends on system parameters (i.e., absorber strength, modal distribution, and vibrational absorber and cavity line widths). Here, we evaluate the impact of absorption coefficient and cavity design on normal mode coupling between a Fabry-Perot cavity and a molecular vibration. For a vibrational band of urethane in a polymer matrix, the coupling strength increases with its concentration so that the system spans the weak and strong coupling regimes. The experimentally determined Rabi splitting values are in excellent agreement with an analytical expression derived for classical coupled oscillators that includes no fitting parameters. Also, the cavity mode profile is altered through choice of mirror type, with metal mirrors resulting in stronger confinement and thus coupling, while dielectric stack mirrors provide higher transmission for a given cavity quality factor and decreased coupling due to greater mode penetration into the dielectric mirror. In addition to polymers, the cavities can couple to molecular vibrational bands of dissolved species in solution, which greatly expands the range of systems that can be explored. Finally, longer path length cavities are used to demonstrate the path length independence of the coupling strength. The ability to adjust the cavity line width, through the use of higher order modes, represents a route to match the cavity dephasing time to that of the molecular vibration and may be applied to a range of molecular systems. Understanding the roles of cavity design and validating empirical and analytical descriptions of absorber properties on coupling strength will facilitate application of these strong coupling effects to enable currently unreachable chemistries.

The site is just east of ship and marine emission sources and is also influenced by continental pollution and wildfires, such as those near the California-Oregon border which occurred near the end of NiCE. Two micro-orifice uniform deposit impactors (MOUDIs) were used, and water-soluble and elemental compositions were measured. The five most abundant water-soluble species (in decreasing order) were chloride, sodium, non-sea salt (nss) sulfate, ammonium, and nitrate. During wildfire periods, nss K mass concentrations were not enhanced as strongly as other species in the sub-micrometer stages and even decreased in the super-micrometer stages; species other than nss K are more reliable tracers for biomass burning in this region. Chloride levels were reduced in the fire sets likely due to chloride depletion by inorganic and organic acids that exhibited elevated levels in transported plumes. During wildfire periods, the mass size distribution of most dicarboxylic acids changed from unimodal to bimodal with peaks in the 0.32 mu m and 1.0-1.8 mu m stages. Furthermore, sulfate's peak concentration shifted from the 032 mu m to 0.56 mu m stage, and nitrate also shifted to larger sizes (1.0 mu m to 1.8-3.2 mu m stages). Mass concentrations of numerous soil tracer species (e.g., Si, Fe) were strongly enhanced in samples influenced by wildfires, especially in the sub-micrometer range. Airborne cloud water data confirm that soil species were associated with fire plumes transported south along the coast. In the absence of biomass burning, cloud condensation nuclei (CCN) composition is dominated by nss sulfate and ammonium, and the water-soluble organic fraction is dominated by methanesulfonate, whereas for the samples influenced by wildfires, ammonium becomes the dominant overall species, and oxalate is the most abundant organic species.

The averaged ISO strength (measured by combined 850-hPa zonal and meridional wind fields) increases by 9% when the realistic TCs are included.

Electrochemical water electrolysis tests conducted in ambient operating conditions on standard SOCs show that NIR imaging can be used to spatially resolve the electrochemically active regions associated with an accumulation of Ce3+. These effective emissivity changes are attributed to changes in optical properties (e.g. the index of refraction) of ceria that occur upon reduction. These data correlate strongly with APXPS measurements, simultaneously supporting the model (near ambient conditions and single-sided cell setup required by APXPS experiments) and the ability to elucidate mechanistic details on an operating SOC using an inexpensive, convenient NIR imaging technique.

We first provide an agent-based programming model for sensor networks. A logical framework enables reasoning about security, safety, and integrity with respect to usage of resources in this model. Embedded sensor networks often operate in rapidly changing mission-critical environments where both functional and nonfunctional requirements can alter dynamically in an unforeseen manner. The network may need to be reconfigured and reprogrammed in response to changes in its operating conditions. We provide a framework based on counterfactual logic to formally represent changes to the system and perform what-if reasoning about their impact on security and safety even before they have been applied.double dagger Copyright (C) 2015 John Wiley & Sons, Ltd.

The world's second largest coastal hypoxic (2mg of O(2)l(-1)) zone occurs annually in the northern Gulf of Mexico. The net effect of hypoxia is the diversion of energy flow away from higher trophic levels to microorganisms. This energy shunt is consequential to the overall productivity of hypoxic water masses and the ecosystem as a whole. In this study, water column samples were collected at 39 sites in the nGOM, 21 of which were hypoxic. Analysis of the microbial community along a hypoxic to oxic dissolved oxygen gradient revealed that the relative abundance (iTag) of Thaumarchaeota species 16S rRNA genes (>40% of the microbial community in some hypoxic samples), the absolute abundance (quantitative polymerase chain reaction; qPCR) of Thaumarchaeota 16S rRNA genes and archaeal ammonia-monooxygenase gene copy number (qPCR) were significantly higher in hypoxic samples. Spatial interpolation of the microbial and chemical data revealed a continuous, shelfwide band of low dissolved oxygen waters that were dominated by Thaumarchaeota (and Euryarchaeota), amoA genes and high concentrations of phosphate in the nGOM, thus implicating physicochemical forcing on microbial abundance.

Baumgartner, Gerald TI Quantum Key Distribution: Examination of the Decoy State Protocol SO IEEE COMMUNICATIONS MAGAZINE LA English DT Article ID SECURITY AB Quantum key distribution (QKD) is an innovative technology that exploits the laws of quantum mechanics to generate and distribute a shared cryptographic key for secure communications. The unique nature of QKD ensures that eavesdropping on quantum communications necessarily introduces detectable errors which is desirable for high-security environments. QKD systems have been demonstrated in both freespace and optical fiber configurations, gaining global interest from national laboratories, commercial entities, and the U.S. Department of Defense. However, QKD is a nascent technology where realized systems are constructed from non-ideal components, which can significantly impact system performance and security. In this article, we describe QKD technology as part of a secure communications solution and identify vulnerabilities associated with practical network architectures. In particular, we examine the performance of decoy state enabled QKD systems against a modeled photon number splitting attack and suggest an improvement to the decoy state protocol security condition that does not assume a priori knowledge of the QKD channel efficiency.

Shear rate effects on viscosity of these suspensions were also systematically addressed. These effects typically have a strong influence on the overall rheological response of materials incorporating any polymeric substance. It was found that the addition of guar gum, even as little as 5% relative to the clay content, increases the viscosity of the floc suspensions significantly. The higher the guar-gum and clay content, the greater is the viscosity of the floc suspensions, within the guar-gum loading range investigated in this study. The floc suspensions with higher solid content were found to exhibit a slight shear thinning behavior, apparently due to the breakdown of the floc structure under high shear stress. This behavior is more pronounced in montmorillonite floc suspensions than in the kaolinite suspensions due to the differences in the clay mineral surface charge properties and surface-to-mass ratios. We explore different rheological models in their applicability to describing the observed viscous response and conclude that a cross-type formulation may be most appropriate.

Frequently, AN is mixed with a fuel and used in improvised explosives devices (IEDs). To characterize the low-volatility components emanating from AN, a sample of AN was sealed inside a stainless steel chamber while a laminar flow of air swept the headspace vapor components into a water impinger or cold-trap for pre-concentration and subsequent analysis by ion chromatography (IC). Both collection methods were found to be 100% efficient for collecting nitric acid vapor, whereas the collection efficiency for ammonia was dependent upon the collection method and, for the water impinging method, additionally upon the vapor concentration, humidity and flow rate. Cold-trapping efficiency for ammonia was 4% +/- 2% across all parameters studied. Water impinging was more efficient (20-70%), but the efficiency varied according to each of the aforementioned variables. The characteristics of an AN vapor generated from a solid sample were found to vary as the sample approached equilibrium inside the chamber. Initially, large quantities of ammonia were observed, but as a steady state was achieved within the laminar flow and a dynamic equilibrium established, the ratio of ammonia to nitric acid in the effluent vapor dropped, although never becoming equimolar. The ratio was strongly dependent upon humidity. C1 [Steinkamp, Frank Lucus] US Naval Res Lab, Washington, DC 20375 USA.

TI Metaproteomic evidence of changes in protein expression following a change in electrode potential in a robust biocathode microbiome SO PROTEOMICS LA English DT Article DE Biocathode; Microbial fuel cell; Microbiology ID TANDEM MASS-SPECTROMETRY; ACIDITHIOBACILLUS-FERROOXIDANS; COMMODITY CHEMICALS; STATISTICAL-MODEL; PROTEOMICS; ELECTROSYNTHESIS; IDENTIFICATIONS; COMMUNITIES; DATABASE AB Microorganisms that respire electrodes may be exploited for biotechnology applications if key pathways for extracellular electron transfer can be identified and manipulated through bioengineering. To determine whether expression of proposed Biocathode-MCL extracellular electron transfer proteins are changed by modulating electrode potential without disrupting the relative distribution of microbial constituents, metaproteomic and 16S rRNA gene expression analyses were performed after switching from an optimal to suboptimal potential based on an expected decrease in electrode respiration. Five hundred and seventy-nine unique proteins were identified across both potentials, the majority of which were assigned to three previously defined Biocathode-MCL metagenomic clusters: a Marinobacter sp., a member of the family Chromatiaceae, and a Labrenzia sp (abbreviated as MCL). Statistical analysis of spectral counts using the Fisher's exact test identified 16 proteins associated with the optimal potential, five of which are predicted electron transfer proteins. The majority of proteins associated with the suboptimal potential were involved in protein turnover/synthesis, motility, and membrane transport. Unipept and 16S rRNA gene expression analyses indicated that the taxonomic profile of the microbiome did not change after 52 h at the suboptimal potential. These findings show that protein expression is sensitive to the electrode potential without inducing shifts in community composition, a feature that may be exploited for engineering Biocathode-MCL.

Spectral density and wavelet analysis of the total precipitable water (TPW) constructed from the DYNAMO soundings and TRMM satellite precipitation reveal a deep layer of vapor resurgence during the observed Wheeler and Hendon real-time multivariate MJO index phases 5-8 (MJO suppressed phase), which include diurnal, quasi-2-, quasi-3-4-, quasi-6-8-, and quasi-16-day oscillations. A similar oscillatory pattern is found in the DYNAMO moorings sea surface temperature analysis, suggesting a tightly coupled atmosphere and ocean system during these periods. COAMPS hindcast focused on the 12-16 November 2011 event suggests that both the diurnal sea surface temperature (SST) pumping and horizontal and vertical moisture transport associated with the westward propagating mixed Rossby-Gravity (MRG) waves play an essential role in the moisture resurgence during this period. Idealized COAMPS simulations of MRG waves are used to estimate the MRG and diurnal SST contributions to the overall moisture increase. These idealized MRG sensitivity experiments showed the TPW increase varies from 9% to 13% with the largest changes occurring in the simulations that included a diurnal SST variation of 2.5 degrees C as observed.

We demonstrate that an electric field typical of those found in neuronal membranes results in suppression of the QD photoluminescence (PL) and, for the first time, that QD PL is able to track the action potential profile of a firing neuron with millisecond time resolution. This effect is shown to be connected with electric-field-driven QD ionization and consequent QD PL quenching, in contradiction with conventional wisdom that suppression of the QD PL is attributable to the quantum confined Stark effect.

These new plasmon modes offer the potential to incorporate a tunable plasmonic channel into a device with electrical contacts, a critical step toward practical graphene terahertz optoelectronics. Through theory and experiments, we demonstrate, for example, anomalously high resonant absorption or transmission when subwavelength graphene-filled apertures are introduced into an otherwise conductive layer.

One common method for determining whether a microorganism or protein can degrade this class of polymer is to qualitatively assess its ability to "clear" a polyester-polyurethane colloid branded Impranil (R) DLN (Impranil), whose formulation is proprietary. However, its colloidal state has ultimately made Impranil a precarious choice for determining if an organism or enzyme can degrade polyurethanes. In this work, the chemical hydrolysis products from Impranil using 0.1 M HCl or 0.1 M NaOH were identified and compared to the concentration of hydrolysis products formed using three commercial enzymes by proton nuclear magnetic spectroscopy (H-1 NMR) and Fourier-transform infrared spectroscopy (FT-IR). The differences in the integrated signal intensities from key H-1 NMR signals were used to calculate the amount of Impranil that was hydrolyzed. These data were then correlated with the change in optical density of colloid containing reaction mixtures (termed as "clearing"). The enzymes (a Pseudomonas fluorescens recombinant esterase, Pseudomonas sp. lipase, and Bacillus sp. protease) showed significant esterase activities and partially-cleared, completely-cleared, or aggregated Impranil, respectively. However, only the Pseudomonas sp. lipase significantly degraded Impranil based on NMR and IR data. This study illustrates how Impranil can be used to quantitatively assess biodegradation rather than just be a qualitative "clearing" indicator of biodegradation. Published by Elsevier Ltd.

The baseline model system is the recently determined crystallographic structure of a llama sdAb (denoted as A3), which exhibits an unusually high thermal stability. An evaluation of the simulation results for the A3 comparative model and crystal structure shows that, despite the overall low C-alpha root-mean-square deviation between the two structures, the model contains misfolded regions that yields a thermal profile of unraveling at a lower temperature. Yet comparison of the simulations of four different comparative models for sdAb A3, C8, A3C8 and E9, where A3C8 is a design of swapping the sequence of the complementarity determining regions of C8 onto the A3 framework, discriminated among the sequences to detect the highest and lowest experimental melting transition temperatures. Further structural analysis of A3 for selected alanine substitutions by a combined computational and experimental study found unexpectedly that the comparative model performed admirably in recognizing substitution 'hot spots' when using a support-vector machine algorithm.

TI Ekman Spiral in a Horizontally Inhomogeneous Ocean with Varying Eddy Viscosity SO PURE AND APPLIED GEOPHYSICS LA English DT Article ID MIXED-LAYER MODEL; BOUNDARY-LAYER; CURRENTS; DEPTH AB The classical Ekman spiral is generated by surface wind stress with constant eddy viscosity in a homogeneous ocean. In real oceans, the eddy viscosity varies due to turbulent mixing caused by surface wind and buoyancy forcing. Horizontally inhomogeneous density produces vertical geostrophic shear which contributes to current shear that also affects the Ekman spiral. Based on similar theoretical framework as the classical Ekman spiral, the baroclinic components of the Ekman spiral caused by the horizontally inhomogeneous density are obtained analytically with the varying eddy viscosity calculated from surface wind and buoyancy forcing using the K-profile parameterization (KPP). Along with the three existing types of eddy viscosity due to pure wind forcing (zero surface buoyancy flux), such an effect is evaluated using the climatological monthly mean data of surface wind stress, buoyancy flux, ocean temperature and salinity, and mixed layer depth.

TI Banning cigarette smoking on US Navy submarines: a case study SO TOBACCO CONTROL LA English DT Article ID TOBACCO CONTROL; MILITARY PERSONNEL; POLICY; PROMOTION; LEADERS; STRESS AB Background The military has had a long pro-tobacco tradition. Despite official policy discouraging smoking, tobacco still is widely seen as part of military culture. While active smoking has presented a particular challenge for the military, in recent years there also has been increasing concern with secondhand smoke. This is especially true in closed environments and submarines may be deployed for months at a time. The current case study describes the successful implementation by the Navy of a comprehensive ban on smoking aboard submarines. Methods The authors searched documents on the internet, popular media, military-based news outlets and the scientific literature. We also conducted interviews with Navy officers who were instrumental in policy implementation. Findings Data demonstrating substantial exposure of non-smokers to tobacco smoke aboard submarines had major impact on successful adoption of the policy. A systematic and extended roll out of the ban included establishing a working group, soliciting input and active engagement from submarine personnel, and offering cessation assistance. Support was enlisted from Chief Petty Officers who could have been strongly opposed but who became strong proponents. Fewer problems were encountered than had been expected. In contrast to a previous unsuccessful attempt by a Navy captain to ban smoking on his ship, the ban was adopted without apparent tobacco industry interference. Conclusions Lessons learned included the importance of strong empirical support, effective framing of the issue, setting a realistic timeline, soliciting support from key personnel and providing appropriate resources. These lessons have implications for those considering further tobacco policy changes in the military and elsewhere.

TI Weighted Analog Technique for Intensity and Intensity Spread Predictions of Atlantic Tropical Cyclones SO WEATHER AND FORECASTING LA English DT Article DE Statistical forecasting ID SITUATION-DEPENDENT INTENSITY; CONSENSUS; GUIDANCE AB A situation-dependent intensity and intensity spread prediction technique for the Atlantic called the Weighted Analog Intensity Atlantic (WAIA) is developed using the same procedures as for a similar technique for the western North Pacific that is operational at the Joint Typhoon Warning Center. These simple techniques are based on rankings of the 10 best historical track analogs to match the official track forecast and current intensity. A key step is the development of a bias correction to eliminate an overforecast bias. The second key step is a calibration of the original intensity spread among the 10 analogs to achieve a probability of detection of about 68% at all forecast intervals, which it is proposed would be an appropriate intensity spread for the National Hurricane Center (NHC) official intensity forecasts. The advantages of WAIA as an operational intensity forecast product for Atlantic tropical cyclones are described in terms of mean absolute errors, sample-mean biases, and geographic distributions of WAIA versus various guidance products available at NHC. Specific attention is given to the four guidance products that are included in the intensity consensus (ICON) technique that is the most skillful of all the products. Evidence is given that WAIA would be an independent, and more likely skillful at longer forecast intervals, technique to include in ICON. Consequently, WAIA would likely lead to improved NHC intensity forecasts at 4-5-day intervals. C1 [Tsai, Hsiao-Chung] Tamkang Univ, Dept Water Resources & Environm Engn, New Taipei City, Taiwan.

TI Evaluating Environmental Impacts on Tropical Cyclone Rapid Intensification Predictability Utilizing Statistical Models SO WEATHER AND FORECASTING LA English DT Article DE Tropical cyclones; Statistical techniques; Forecasting techniques; Model evaluation; performance ID PREDICTION SCHEME SHIPS; NORTH PACIFIC BASINS; HURRICANE-OPAL 1995; GULF-OF-MEXICO; INTENSITY CHANGE; WARM-CORE; PART II; ATLANTIC; IMPROVEMENTS; CLIMATOLOGY AB New multi-lead-time versions of three statistical probabilistic tropical cyclone rapid intensification (RI) prediction models are developed for the Atlantic and eastern North Pacific basins. These are the linear-discriminant analysis-based Statistical Hurricane Intensity Prediction Scheme Rapid Intensification Index (SHIPS-RII), logistic regression, and Bayesian statistical RI models. Consensus RI models derived by averaging the three individual RI model probability forecasts are also generated. A verification of the cross-validated forecasts of the above RI models conducted for the 12-, 24-, 36-, and 48-h lead times indicates that these models generally exhibit skill relative to climatological forecasts, with the eastern Pacific models providing somewhat more skill than the Atlantic ones and the consensus versions providing more skill than the individual models. A verification of the deterministic RI model forecasts indicates that the operational intensity guidance exhibits some limited RI predictive skill, with the National Hurricane Center (NHC) official forecasts possessing the most skill within the first 24 h and the numerical models providing somewhat more skill at longer lead times. The Hurricane Weather Research and Forecasting Model (HWRF) generally provides the most skillful RI forecasts of any of the conventional intensity models while the new consensus RI model shows potential for providing increased skill over the existing operational intensity guidance. Finally, newly developed versions of the deterministic rapid intensification aid guidance that employ the new probabilistic consensus RI model forecasts along with the existing operational intensity model consensus produce lower mean errors and biases than the intensity consensus model alone.

TI A Consensus Forecast for Tropical Cyclone Gale Wind Radii SO WEATHER AND FORECASTING LA English DT Article DE Tropical cyclones; Forecast verification; skill; Forecasting techniques; Operational forecasting; Statistical forecasting ID CLIMATOLOGY AB The National Hurricane Center (NHC) has been forecasting gale force wind radii for many years, and more recently (starting in 2004) began routine postanalysis or best tracking of the maximum radial extent of gale [34 knots (kt; 1 kt = 0.514 m s(-1))] force winds in compass quadrants surrounding the tropical cyclone (wind radii). At approximately the same time, a statistical wind radii forecast, based solely on climatology and persistence, was implemented so that wind radii forecasts could be evaluated for skill. If the best-track gale radii are used as ground truth (even accounting for random errors in the analyses), the skill of the NHC forecasts appears to be improving at 2- and 3-day lead times, suggesting that the guidance has also improved. In this paper several NWP models are evaluated for their skill, an equally weighted average or consensus of the model forecasts is constructed, and finally the consensus skill is evaluated. The results are similar to what is found with tropical cyclone track and intensity in that the consensus skill is comparable to or better than that of the individual models. Furthermore, the consensus skill is high enough to be of potential use as forecast guidance or as a proxy for official gale force wind radii forecasts at the longer lead times.

TI Growth of High Crystalline Quality HVPE-GaN Crystals with Controlled Electrical Properties SO CRYSTAL GROWTH & DESIGN LA English DT Article ID AMMONOTHERMAL GAN; BULK GAN; SEEDS AB Thick free-standing hydride vapor phase epitaxy (HE) GaN wafers were grown with close to perfect crystalline quality and with more than two orders of magnitude reduced free carrier concentration relative to ammonothermal GaN without resorting to deep level compensation. These new homoepitaxially grown crystals exceed the quality of any commercially available GaN substrates. High crystalline quality is confirmed by XRD rocking curve measurements having full width at half-maximum of only 16 arc s. Detailed Raman scattering spectroscopy and imaging show that the wafers are biaxially stress-free and have a uniform and low background doping. The stress-free, flat nature of these substrates is essential for high-yield device fabrication. High-resolution photoluminescence studies in combination with SIMS analysis identify Si and 0 as residual shallow donors with concentration levels orders of magnitude lower than those present in ammonothermal GaN substrates.

TI Reflection-Mode Bandstop Filters With Minimum Through-Line Length SO IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES LA English DT Article DE Filter design; filters; filter synthesis; microwave filters; passive filters ID BANDPASS-FILTERS; COUPLING MATRIX; NETWORKS AB This paper presents a technique that enables the design of high-order microwave bandstop filters with a total through-line length of significantly less than one quarter-wavelength at the filter center frequency. The total through-line length using this technique can be zero regardless of the filter order in theory, but it is limited in practice by the finite line length required to obtain a desired coupling magnitude between the through line and a resonator. A fifth-order quasi-elliptic reflection-mode bandstop filter design is shown with total through-line length of less than 1/15th of a wavelength in suspended-stripline technology. The measured response has a 42-MHz 30-dB bandwidth at a center frequency of 3 GHz and four reflection zeros. The bandstop filter design technique described in this paper shows great promise for reducing the size and weight of microwave bandstop filters.

TI Current Density Scaling Expressions for a Bipolar Space-Charge-Limited Cylindrical Diode SO IEEE TRANSACTIONS ON PLASMA SCIENCE LA English DT Article DE Bipolar flow; current density; cylindrical diodes; space-charge limited (SCL) ID HIGH-POWER; INDUSTRIAL APPLICATIONS; ELECTRON; BEAMS; FLOW AB Exact analytical solutions for the currents in a bipolar space-charge-limited (SCL) diode in cylindrical geometry do not exist. Expressions for the electron and ion current densities as functions of the diode cathode and anode radii and the applied voltage are developed and fit to numerical solutions. The results are provided for nonrelativistic and relativistic electrons. These provide scaling relations for the diode, which were not previously available. They also converge to known planar diode expressions in the appropriate limit. The relativistic scaling relations are then combined with nonrelativistic results using a fit function technique to provide a general expression for the current densities valid for all values of the diode voltage. The results are presented for both negative and positive polarities. For completeness, single-species SCL flow results in cylindrical geometry are also developed using the same techniques presented here for bipolar SCL flow and are included in the Appendix.

The study objective was to characterize the epidemiology of airway management in maxillofacial trauma. Study Design Retrospective database analysis. Setting Military treatment facilities in Iraq and Afghanistan and stateside tertiary care centers. Subjects In total, 1345 military personnel with combat-related maxillofacial injuries sustained March 2004 to August 2010 were identified from the Expeditionary Medical Encounter Database using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes. Methods Descriptive statistics, including basic demographics, injury severity, associated injuries, and airway interventions, were collected. A logistic regression was performed to determine factors associated with the need for tracheostomy. Results A total of 239 severe maxillofacial injuries were identified. The most common mechanism of injury was improvised explosive devices (66%), followed by gunshot wounds (8%), mortars (5%), and landmines (4%). Of the subjects, 51.4% required intubation on their initial presentation. Of tracheostomies, 30.4% were performed on initial presentation. Of those who underwent bronchoscopy, 65.2% had airway inhalation injury. There was a significant relationship between the presence of head and neck burn and association with airway inhalation injury (P < .0001). There was also a significant relationship between the severity of facial injury and the need for intubation (P = .002), as well as the presence of maxillofacial fracture and the need for tracheostomy (P = .0001). Conclusions There is a high incidence of airway injury in combat maxillofacial trauma, which may be underestimated. Airway management in this population requires a high degree of suspicion and low threshold for airway stabilization.

TI Sleep Duration in Rough Sea Conditions SO AEROSPACE MEDICINE AND HUMAN PERFORMANCE LA English DT Article DE sleep; sopite syndrome; motion sickness ID MOTION SICKNESS; SOPITE SYNDROME; CIRCADIAN-RHYTHMS AB INTRODUCTION: Environmental motion can affect shipboard sleep of crewmembers. Slamming and similar harsh motion may interfere with sleep, whereas mild motion and sopite syndrome may enhance sleep. If sleep needs vary by sea condition, this factor should be considered when assessing human performance at sea. The goal of this study was to assess sleep duration in different sea conditions. METHODS: Crewmembers (N = 52) from a U.S. Navy vessel participated in the study while performing their normal daily schedule of duties. Sleep was assessed with wrist-worn actigraphy. Motion sickness and sopite syndrome were assessed using standardized questionnaires. RESULTS: In rough sea conditions, crewmembers experienced increased severity of motion sickness and sopite syndrome compared to their ratings during calmer sea conditions. Crewmembers slept significantly longer during sea state 5-6 compared to sleep on days with sea state 4 (25% increase) and sea state 3-4 (30% increase). Specifically, daily sleep increased from 6.97 +/- 1.24 h in sea state 3-4, to 7.23 +/- 1.65 h in sea state 4, to 9.04 +/- 2.90 h in sea state 5-6. DISCUSSION: Although the duration of sleep in rough seas increased significantly compared to calmer sea conditions, causal factors are inconclusive. Accumulated sleep debt, motion-induced fatigue, and sopite syndrome all may have contributed, but results suggest that motion sickness and sopite syndrome were the predominant stressors. If sleep needs increase in severe motion environments, this factor should be taken into account when developing daily activity schedules or when modeling manning requirements on modern ships.

Nelson, Eric A. TI "Do we need to memorize that?" or cognitive science for chemists SO FOUNDATIONS OF CHEMISTRY LA English DT Article DE Chemical education research; Automaticity; Cognitive science ID WORKING-MEMORY; CAPACITY AB In introductory chemistry courses, should students be encouraged to solve problems by reasoning based on conceptual understanding or by applying memorized facts and algorithms? Cognitive scientists have recently studied this issue with the assistance of new technologies. In the current consensus model for cognition, during problem solving the brain relies on "working memory" to sequentially process small elements of knowledge. Working memory is able to hold and manipulate virtually all elements that can be recalled "with automaticity" from long-term memory, but very few elements that are not recallable. As one consequence, students can reliably solve well-structured science problems only if most of the facts and algorithms needed to solve the problem have previously been well memorized. To achieve automaticity in recall, facts and procedures must be committed to memory (assimilated) and then tagged with associations to other knowledge (accommodated) in the brain's conceptual frameworks. Accommodation can be assisted by guided inquiry. Articles citing methods that can assist students in the development of automaticity are listed, and implications for chemistry instruction are discussed.

TI Two-Way Pattern Grating Lobe Control for Distributed Digital Subarray Antennas SO IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION LA English DT Article DE Distributed subarray antennas; grating lobe (GL) suppression; two-way pattern; virtual elements ID ARRAY; ELEMENTS AB An approach to controlling the two-way pattern (i.e., the product of the transmitting and receiving antenna patterns) for a distributed digital subarray antenna (DDSA) is presented. Collectively combining periodic widely separated sub-arrays results in grating lobes (GLs), and they are unwanted because of the ambiguities that accompany them. The approach to GL control presented here involves a combination of conventional suppression methods on the transmitting side and in the digital beamforming on the receiving side, filling the gaps between the subarrays with "virtual" elements, thus forming a contiguous array. Individually, the transmitting and receiving antenna patterns may not have adequate performance, but it is demonstrated that if designed to complement each other, the two-way pattern can achieve ultralow sidelobe performance. The effects of receiving element signal-to-noise ratio (SNR) and errors in calibration are also addressed. C1 [Feng, Bo-Kai] Natl Chung Shan Inst Sci & Technol, Longtan 32546, Taiwan.

The formulation includes the effects of shear forces on displacements and stresses and of the beam curvature on the distribution of bending and torsional stress over the cross section. The element is coherent with the well-known theory for straight beams, which is obtained exactly as the curvature radius becomes infinite. The numerical predictions for a test case compare favourably with published analytical and experimental results and with the outcome of a purposely developed, large-scale FE brick model.

TI "Twisted Beam" SEE Observations of Ionospheric Heating from HAARP SO EARTH MOON AND PLANETS LA English DT Article DE Ionospheric modification; Orbital angular momentum; Twisted beam AB Nonlinear interactions of high power HF radio waves in the ionosphere provide aeronomers with a unique space-based laboratory capability. The High-Frequency Active Auroral Research Program (HAARP) in Gakona, Alaska is the world's largest heating facility, yielding effective radiated powers in the gigawatt range. New results are present from HAARP experiments using a "twisted beam" excitation mode. Analysis of twisted beam heating shows that the SEE results obtained are identical to more traditional patterns. One difference in the twisted beam mode is the heating region produced is in the shape of a ring as opposed to the more traditional "solid spot" region from a pencil beam. The ring heating pattern may be more conducive to the creation of stable artificial airglow layers because of the horizontal structure of the ring. The results of these runs include artificial layer creation and evolution as pertaining to the twisted beam pattern. The SEE measurements aid the interpretation of the twisted beam interactions in the ionosphere. C1 [Briczinski, S. J.; Bernhardt, P. A.; Siefring, C.

The validity of this law is illustrated by results of numerical simulations, in situ measurements of growing wind seas and wind-wave tank observations.

Initial tests are conducted to determine the correct procedure and materials to properly fabricate a carbon nanotube (CNT) based sensor, which is then placed in between a composite patch and the aluminum structure. The CNTs have been utilized as sensors in previous studies but only for sensing crack propagation within the composite itself. This study focuses on crack propagation in the base material and is not concerned with the composite. In this application, the composite is only a patch and can be replaced if damaged. The study conducts both tension and fatigue testing to determine the usefulness of the CNT sensor. The CNT sensor is shown to be effective in giving an indication of the crack propagation in the aluminum. Correlation is done between the crack propagation length and the increase in electrical resistance in the CNT sensor under tensile and cyclic loading, respectively. C1 [Olson, T. M.; Kwon, Y.

The etiologic agent of AHPND has recently been identified as a unique strain of Vibrio parahaemolyticus: One that is different from human pathogenic V. parahaemolyticus strains. In this study, two sets of primers (LAMP-A2 and LAMP-A3) were developed and validated for use in a LAMP assay to specifically identify V. parahaemolyticus causing AHPND (V. parahaemolyticus AHPND). LAMP-A2 and LAMP-A3 detected all 33 V. parahaemolyticus AHPND isolates except the non-V. parahaemolyticus AHPND isolates and 19 other closely related bacterial species. In pure culture and in spiked shrimp experiments, the LAMP assay was superior to PCR for the detection of V. parahaemolyticus AHPND. In pure cultures, the detection limit of LAMP-A3 was 53 CFU/ml or 0.1 CFU per reaction (10x lower than LAMP-A2), whereas in spiked shrimp experiments, the detection limit was 4.4 x 10(5) CFU/ml or 8.8 x 10(2) CFU per reaction. Further testing of 24 post-larvae, shrimp, sediment and water samples collected from a shrimp farm revealed that V. parahaemolyticus AHPND was detected mostly in the sediment samples. Taken together, the results suggested that the LAMP-A3-based LAMP assay, but not LAMP-A2 or PCR, was suitable for the identification of V. parahaemolyticus AHPND in shrimp aquaculture.

Despite standard treatment modalities, which typically include surgery and medical management of allergies, patients still have a high rate of recurrence. Subcutaneous immunotherapy (SCIT) has been used as adjuvant treatment for AFS. Evidence exists to support the use of sublingual immunotherapy (SLIT) as a safe and efficacious method of treating allergies, but no studies have assessed the utility of SLIT in the management of allergic fungal sinusitis. A record review of cases of AFS that are currently or previously treated with sublingual immunotherapy from 2007 to 2011 was performed. Parameters of interest included serum IgE levels, changes in symptoms, Lund-McKay scores, decreased sensitization to fungal allergens associated with AFS, and serum IgE levels. Ten patients with diagnosed AFS were treated with SLIT. No adverse effects related to the use of SLIT therapy were identified. Decreases in subjective complaints, exam findings, Lund-McKay scores, and serum IgE levels were observed. Thus, sublingual immunotherapy appears to be a safe adjunct to the management of AFS that may improve patient outcomes.

As future new fuels will likely be used in both older mechanical injected engines as well as newer high pressure common rail engines, the question as to the sensitivity of a new fuel type across a range of engines is of concern. In this study, conventional diesel fuel (Navy NATO F76) was compared with the new Navy hydroprocessed renewable diesel (HRD) fuel from algal sources, as well as the high cetane reference fuel nC16 (n-hexadecane CN = 100). It was seen that, in general, ignition delay (IGD) was shortened for all fuels with increasing fuel injection pressure and was shortened with higher CN fuels. The combustion duration for all fuels was also significantly reduced with increasing fuel injection pressure, however, longer durations were seen for higher CN fuels at the same fuel pressure due to less premixing before the start of combustion. Companion modeling using the Lawrence Livermore National Lab (LLNL) heavy hydrocarbon and diesel primary reference fuel (PRF) chemical kinetic mechanisms for HRD and nC16 was applied to understand the relative importance of the physical and chemical delay periods of the IGD. It was seen that at low fuel injection pressures, the physical and chemical delay times are of comparable duration. However, as injection pressure increases the importance of the chemical delay times increases significantly (longer), especially with the lower CN fuel.

About three quarters of these toxic blooms are caused by dinoflagellate species. One dinoflagellate species, i.e., Karenia brevis, blooms nearly every year in the Gulf of Mexico, particularly on the West Florida Shelf (WFS), where these blooms cause millions of dollars in socioeconomic damage. In this letter, we use the red band difference (RBD) bloom detection technique for detection of low backscattering phytoplankton blooms, such as K. brevis, and conduct time-series analyses of the spatial extent of these blooms using Moderate Resolution Imaging Spectroradiometer (MODIS) monthly mean data spanning July 2002 (sensor inception) to September 2014. The time-series results show that the RBD successfully detects the documented HABs in the region, illustrating the seasonal and interannual variability, including the extensive blooms of 2005 and 2014.

TI Modelling field emitter arrays using line charge distributions SO JOURNAL OF PHYSICS D-APPLIED PHYSICS LA English DT Article DE field emitters; electrostatics; cathodes ID ELECTRON-EMISSION; CARBON NANOTUBE; SURFACE; ENHANCEMENT AB Field emitter arrays are high-brightness electron sources with important current and future applications in vacuum electronics, particle accelerators, and directed energy. The current produced by individual emitters in these arrays is controlled by the total electric field on their surfaces, which depends on the background field, the space charge field from previously-emitted electrons, and field enhancements due to geometric features at the macro-, meso-, and micro-scales. To facilitate the study of shielding and space charge effects in these arrays, we have developed a mathematical model using tapered line charges to generate equipotential surfaces which approximate the geometry of high aspect ratio field emitters. This model provides an analytic approach for studying contributions to array performance due to macro-scale and meso-scale features such as array geometry, emitter height, and emitter tip radius. Here we present this model and use it to assess the impact of these parameters on the field enhancement factor of individual field emitters and emitters in 1D and 2D arrays. C1 [Harris, J.

It is shown that the projectile experiences a force perpendicular to its direction of motion as one side of the projectile passes through a channel of reduced air density. A single channel of reduced air density can be generated by the energy deposited from filamentation of an intense laser pulse. We propose changing the laser pulse energy from shot-to-shot to build longer effective channels. Current femtosecond laser systems with multi-millijoule pulses could provide trajectory correction of several meters on 5 km trajectories for sub-kilogram projectiles traveling at Mach 3.

The antenna is comprised of a two-dimensional waveguide patterned with radiating acoustic shunts. When excited using a single acoustic source within the waveguide, the antenna acts as a sonic prism that exhibits frequency steering. This design allows for control of acoustic steering angle using only a single source transducer and a patterned aperture. Aperture design was determined using transmission line analysis and finite element methods. The designed antenna was fabricated and the steering angle measured. The performance of the measured aperture was within 9% of predicted angle magnitudes over all examined frequencies. (C) 2015 AIP Publishing LLC.

At high sample bias voltages (approaching + 10 V), a series of well defined resonances are identified as the typical Stark shifted image states that are commonly found on metallic surfaces in the form of field emission resonances (FER). At lower bias voltages, a more complex situation arises. Up to three double peaks are identified as the first three FERs that are split due to their interaction with the periodic surface potential. The high corrugation of this potential is also quantified by means of density functional theory (DFT) calculations. Another sharp resonance not belonging to the FER series is associated with an unoccupied surface state.

TI Structure versus Composition: A Single-Particle Investigation of Plasmonic Bimetallic Nanocrystals SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID OPTICAL-PROPERTIES; GOLD NANOCRYSTALS; METAL NANOPARTICLES; SILVER NANOCUBES; NOBLE-METALS; SIZE; SHAPE; RESONANCE; SPECTROSCOPY; AG AB Stellated bimetallic nanostructures are a new class of plasmonic colloids in which the interplay between composition and overall architecture can provide tunable optical properties and new functionality. However, decoupling the complex compositional and structural contributions to the localized surface plasmon resonance (LSPR) remains a challenge, especially when the monometallic counterparts are not synthetically accessible for comparison. Here, stellated Au-Pd nanocrystals (NCs) with O-h symmetry are used as a model system to decouple structural and complex compositional effects on LSPR. Single-particle correlation of the LSPR with the structure of octopodal Au-Pd NCs was achieved using optical dark-field spectroscopy with scanning electron microscopy. These measurements were compared to calculations of the optical properties of structurally similar Au-only octopods by the finite difference time domain method. This comparison enabled the role of complex composition, which was determined by scanning transmission electron microscopy energy-dispersive spectrometry measurements, on the LSPR to be elucidated from the structural contributions. This methodology provides a powerful framework to guide the design of new plasmonic colloids through both structure and composition.

TI Decay and Fission Hindrance of Two- and Four-Quasiparticle K Isomers in (254)Rf SO PHYSICAL REVIEW LETTERS LA English DT Article ID NUCLEI; STATES; FM-250; NO-254 AB Two isomers decaying by electromagnetic transitions with half-lives of 4.7(1.1) and 247(73) mu s have been discovered in the heavy (254)Rf nucleus. The observation of the shorter-lived isomer was made possible by a novel application of a digital data acquisition system. The isomers were interpreted as the K-pi = 8(-), nu(2)(7/2(+)[624]; 9/2(-)[734]) two-quasineutron and the K-pi = 16(+), 8(-)nu(2)(7/2(+)[624]; 9/2(-)[734] circle times 8(-)pi(2) (7/2(-)[514]; 9/2(+)[624]) four-quasiparticle configurations, respectively. Surprisingly, the lifetime of the two-quasiparticle isomer is more than 4 orders of magnitude shorter than what has been observed for analogous isomers in the lighter N = 150 isotones. The four-quasiparticle isomer is longer lived than the (254)Rf ground state that decays exclusively by spontaneous fission with a half-life of 23.2(1.1) mu s. The absence of sizable fission branches from either of the isomers implies unprecedented fission hindrance relative to the ground state. C1 [David, H. M.; Chen, J.; Seweryniak, D.; Kondev, F.

AVIRIS with 224 bands from 0.4 to 2.5 mu m were converted to reflectance. HyTES data with 256 bands covering 8 to 12 mu m were converted to emissivity. Two approaches were investigated for integration of the datasets for full spectrum analysis. A combined (integrated) bands method utilized 332 spectral bands spanning both datasets. Spectral endmembers were extracted, and the predominant material at each pixel was mapped for the full spectral range using partial unmixing. This approach separated a variety of materials, but it was difficult to directly relate mapping results to surface properties. The second method used visible to near-infrared, shortwave infrared, and longwave infrared data independently to determine and map key endmembers in each spectral range. AVIRIS directly mapped a variety of specific minerals, while HyTES separated and mapped several igneous rock phases. Individual mapping results were then combined using geologically directed logical operators. The full-range results illustrate that integrated analysis provides advantages over use of just one spectral range, leading to improved understanding of the distribution of geologic units and alteration.

TI Examining the Polyproline Nanoscopic Ruler in the Context of Quantum Dots SO CHEMISTRY OF MATERIALS LA English DT Article ID RESONANCE ENERGY-TRANSFER; SINGLE-MOLECULE FLUORESCENCE; POLY-L-PROLINE; II CONFORMATIONAL BIAS; SPECTROSCOPIC RULER; GOLD NANOPARTICLES; COLLOIDAL NANOPARTICLES; ELECTRON-TRANSFER; MODEL PEPTIDES; CIS RESIDUES AB The rigidity and defined length of the polyproline type II helix (PPII) have made it the structural basis of a nanoscopic ruler, which has been widely applied in Forster resonance energy transfer (FRET) studies. A growing body of data, however, has questioned the foundation for this and has provided evidence for structural perturbations to the PPII caused by temperature, salt content, solvent polarity, and even Pro repeat length. Here, we examine the polyproline ruler in the context of semiconductor quantum dots (QDs) and FRET. For this study, a series of polyproline peptides (Pro(n), n = 0, 3, 6, 9, 12, 15, 18) displaying a C-terminal hexahistidine sequence (His(6)) and an N-terminal cysteine for site-specific labeling with Cy3 dye were synthesized. Peptide rigidity was first examined with ATTO 647 Ni2+-nitrilotriacetic acid acceptor dye coordinated to the His(6)-termini of the Cy3 donor-labeled peptides. These conditions provided a steady-state fluorescent response that closely followed FRET predictions derived from the expected donor-acceptor distances; this confirmed the PPII conformation and nanoscopic ruler in the context of our sequences. Peptides were next assembled to negatively charged dihydrolipoic acid functionalized 530 nm emitting QDs, which then acted as a donor to the Cy3 acceptor. These data revealed decreases in FRET efficiency E but at significantly less than the magnitude predicted. Lastly, peptides were assembled to neutral poly(ethylene glycol) or PEG-appended dihydrolipoic acid functionalized 530 nm QDs, and here FRET E did not change as peptide length increased. The latter observations were confirmed with excited-state lifetime measurements and single-pair FRET analysis. Circular dichroism spectroscopy was performed on select peptides both free in solution and as assembled to the PEGylated QDs along with physical characterization by dynamic light scattering and electrophoretic mobility. Overall, analysis confirms the initial validity of the rigid polyproline ruler, while it also suggests that peptide subpopulations adopt a different conformation when attached to QDs. Rather than a gross structural rearrangement, this change is consistent with a trans to cis bond reversion in some of the Pro-Pro peptidyl bond(s), which alters persistence length. This suggests that the PPII is highly context dependent and can be strongly influenced by microenvironments or interfacial effects and thus requires careful consideration of experimental format and related factors before being implemented with nanopartides.

TI Interband cascade lasers with > 40% continuous-wave wallplug efficiency at cryogenic temperatures SO APPLIED PHYSICS LETTERS LA English DT Article ID HIGH-POWER AB Broad-area 10-stage interband cascade lasers (ICLs) emitting at lambda = 3.0-3.2 gamma m are shown to maintain continuous-wave (cw) wallplug efficiencies exceeding 40% at temperatures up to 125 K, despite having a design optimized for operation at ambient and above. The cw threshold current density at 80K is only 11 A/cm(2) for a 2mm cavity with anti-reflection/high-reflection coatings on the two facets. The external differential quantum efficiency for a 1-mm-long cavity with the same coatings is 70% per stage at 80 K, and still above 65% at 150 K. The results demonstrate that at cryogenic temperatures, where free carrier absorption losses are minimized, ICLs can convert electrical to optical energy nearly as efficiently as the best specially designed intersubband-based quantum cascade lasers.

The presence of graphene resulted in two types of chiral signatures in the LCs: an electroclinic effect (a polar tilt of the LC director perpendicular to, and linear in, an applied electric field) in the smectic-A phase of 9OO4, and a macroscopic helical twist of the LC director in the nematic phase of 5CB. Graphene flakes generally possess strain chirality and edge chirality. The non-covalent interactions between the LC molecules and chiral graphene flakes induce molecular conformational deracemization in the LC, exhibiting a bulk electroclinic effect and a macroscopic helical twist.

In its 2010 periastron passage, multiwavelength emission from radio to TeV was observed, as well as an unexpected GeV flare measured by the Fermi Large Area Telescope (LAT). Here, we report the results of LAT monitoring of PSR B1259-63 during its most recent 2014 periastron passage. We compare the gamma-ray behavior in this periastron with the former in 2010 and find that PSR B1259-63 shows a recurrent GeV flare. The similarities and differences in the phenomenology of both periastron passages are discussed. C1 [Caliandro, G.

Kane, Charles L. TI Dirac Semimetals in Two Dimensions SO PHYSICAL REVIEW LETTERS LA English DT Article ID INSULATORS; GRAPHENE AB Graphene is famous for being a host of 2D Dirac fermions. However, spin-orbit coupling introduces a small gap, so that graphene is formally a quantum spin Hall insulator. Here we present symmetry-protected 2D Dirac semimetals, which feature Dirac cones at high-symmetry points that are not gapped by spin-orbit interactions and exhibit behavior distinct from both graphene and 3D Dirac semimetals. Using a two-site tight-binding model, we construct representatives of three possible distinct Dirac semimetal phases and show that single symmetry-protected Dirac points are impossible in two dimensions. An essential role is played by the presence of nonsymmorphic space group symmetries. We argue that these symmetries tune the system to the boundary between a 2D topological and trivial insulator. By breaking the symmetries we are able to access trivial and topological insulators as well as Weyl semimetal phases.

TI Sample port design for ballast water sampling: Refinement of guidance regarding the isokinetic diameter SO MARINE POLLUTION BULLETIN LA English DT Article DE Aquatic nuisance species; Compliance; Invasive species; Sampling; Ballast water ID ORGANISMS; TANKS AB By using an appropriate in-line sampling system, it is possible to obtain representative samples of ballast water from the main ballast line. An important parameter of the sampling port is its "isokinetic diameter" (D-ISO), which is the.diameter calculated to determine the velocity of water in the sample port relative to the velocity of the water in the main ballast line. The guidance in the U.S. Environmental Technology Verification (ETV) program protocol suggests increasing the diameter from 1.0 x D-ISO (in which velocity in the sample port is equivalent to velocity in the main line) to 1.5-2.0 x D-ISO. In this manner, flow velocity is slowed-and mortality of organisms is theoretically minimized as water enters the sample port. This report describes field and laboratory trials, as well as computational fluid dynamics modeling, to refine this guidance. From this work, a No of 1.0-2.0 x (smaller diameter sample ports) is recommended. (C) 2015 Elsevier Ltd. All rights reserved.

The circulation of human adenovirus type 21 (HAdV21) in the United States has been documented since the 1960s in association with outbreaks of febrile respiratory illness (FRI) in military boot camps and civilian cases of respiratory disease. Methods.aEuro integral To describe the molecular epidemiology of HAdV21 respiratory infections across the country, 150 clinical respiratory isolates obtained from continuous surveillance of military recruit FRI, and 23 respiratory isolates recovered from pediatric and adult civilian cases of acute respiratory infection were characterized to compile molecular typing data spanning 37 years (1978-2014). Results.aEuro integral Restriction enzyme analysis and genomic sequencing identified 2 clusters of closely related genomic variants readily distinguishable from the prototype and designated 21a-like and 21b-like. A-like variants predominated until 1999. A shift to b-like variants was noticeable by 2007 after a 7-year period (2000-2006) of cocirculation of the 2 genome types. US strains are phylogenetically more closely related to European and Asian strains isolated over the last 4 decades than to the Saudi Arabian prototype strain AV-1645 isolated in 1956. Conclusions.aEuro integral Knowledge of circulating HAdV21 variants and their epidemic behavior will be of significant value to local and global FRI surveillance efforts.

This study reports the design and experimental realization of an acoustic gradient-index lens using a sonic crystal lattice that is impedance matched to water over a broad bandwidth. In contrast to previous designs, the underlying lattice features refractive indices that are lower than the water background, which facilitates propagation control based on a phase advance as opposed to a delay. The index gradient is achieved by varying the filling fraction of hollow, air-filled aluminum tubes that individually exhibit a higher sound speed than water and matched impedance. Acoustic focusing is observed over a broad bandwidth of frequencies in the homogenization limit of the lattice, with intensity magnifications in excess of 7 dB. An anisotropic lattice design facilitates a flat-faceted geometry with low backscattering at 18 dB below the incident sound-pressure level.

TI Atmospheric correction for global mapping spectroscopy: ATREM advances for the HyspIRI preparatory campaign SO REMOTE SENSING OF ENVIRONMENT LA English DT Article DE Imaging spectroscopy; HyspIRI mission; Atmospheric correction ID VEGETATION LIQUID WATER; AVIRIS DATA; IMAGING SPECTROSCOPY; SATELLITE SIGNAL; SOLAR SPECTRUM; SIERRA-NEVADA; RETRIEVAL; ALGORITHM; ABSORPTION; SNOWMELT AB Orbital imaging spectrometers, such as the proposed Hyperspectral Infrared Imager (HyspIRI) mission, will provide global, multi-year Visible Shortwave Infrared (VSWIR) reflectance maps. Monitoring the Earth's surface at high spectral resolution will advance our understanding of changing ecosystems and land use. These applications depend on reliable correction of atmospheric scattering and absorption. The HyspIRI Preparatory Campaign is an airborne precursor mission comprised of multiple flights by the "classic" Airborne Visible Infrared Imaging Spectrometer (AVIRIS-C) over a wide geographic area. This article describes the atmospheric correction that we have implemented for the campaign. We first present the theoretical basis of our approach, which is grounded in the ATmospheric REMoval (ATREM) algorithm. We then describe new enhancements including retrieval of pressure altitude, which improves accuracy over widely varying topography, and joint retrieval of optical absorption for three phases of water (vapor, liquid, and ice), which improves accuracy over vegetated areas. Reflectance is validated using ground spectra acquired across a wide range of targets and elevations. Finally, we use the algorithm to map vapor, liquid, and ice phases of water over 6 months across a 14,000 km(2) region of California. (C) 2015 Elsevier Inc. All rights reserved.

We derive an expression for the output photocurrent in terms of the launch state and the link characteristics. We verify the theoretical description with an experimental investigation of a photonic link into which controlled polarization-dependent losses are introduced. The experimental results confirm a surprising theoretical conclusion: the distortion caused by polarization-dependent loss is equivalent to a simple system phase shift.

TI Effect of carbon nanotube interfacial geometry on thermal transport in solid-liquid phase change materials SO APPLIED ENERGY LA English DT Article DE Phase change materials; Multi-walled carbon nanotubes; Phonon; Thermal conductivity; Constriction resistance; Thermal boundary conductance ID GRAPHITE NANOFIBERS; ENERGY-STORAGE; CONDUCTIVITY; RESISTANCE; GRAPHENE; COMPOSITES; NANOCOMPOSITES; SUSPENSIONS; NANOFLUIDS; MANAGEMENT AB For nearly two decades, research groups have attempted to increase the thermal conductivity of bulk materials by saturating them with different concentrations and types of nanoparticles. However, optimal enhancements in the thermal conductivity of these materials continue to go unrealized, primarily due to interfacial phenomena that impede phonon propagation from the bulk material to the nanoparticle or between individual, contacting nanoparticles. Though it is almost certain that interfacial resistances between contacting nanoparticles are responsible for the underwhelming thermal performance of nanoparticles in bulk materials, the physical mechanisms that limit thermal transport at nanoparticle junctions is not well understood. In this study, we investigate the effect of nanoparticle constriction size (i.e. the contact area between linked nanoparticles) on the bulk thermal conductivity of a surrounding paraffin-based phase change material. To this end, we measure the effective thermal conductivity of different Multi-walled Carbon Nanotube (MWCNT)/paraffin nanocomposites is measured with the transient plane source technique. Using a newly developed physical model, the interfacial thermal resistance between the contacting nanoparticles is determined as a function of the constriction geometry. Results suggest that the thermal conductance (i.e. the rate of heat transfer) between contacting MWCNTs can be increased by a factor of 27 by increasing their diameter by only 58 nm. This is in direct conflict with effective medium approximations, which predict an increase in the bulk thermal conductivity of MWCNT-PCM composites when MWCNT diameters are reduced. Such a result indicates that the contact area between individual, contacting nanoparticles has a significant impact on thermal transport within the PCM nanocomposite, and therefore its bulk thermal conductivity. It is expected that these results will strongly impact the design of nanoparticle-laden PCMs. (C) 2015 Elsevier Ltd. All rights reserved.

We describe a novel cometary disruption mechanism whereby comet nuclei fragment and disperse through dynamic sublimation pressure, which induces differential stresses within the interior of the nucleus. When these differential stresses exceed its material strength, the nucleus breaks into fragments. We model the sublimation process thermodynamically and propose that it is responsible for the disruption of Comet ISON. We estimate the bulk unconfined crushing strength of Comet ISON's nucleus and the resulting fragments to be 0.5 Pa and 1-9 Pa, respectively, assuming typical Jupiter Family Comet (JFC) albedos. However, if Comet ISON has an albedo similar to Pluto, this strength estimate drops to 0.2 Pa for the intact nucleus and 0.6-4 Pa for its fragments. Regardless of assumed albedo, these are similar to previous strength estimates of JFCs. This suggests that, if Comet ISON is representative of dynamically new comets, then low bulk strength is a primordial property of some comet nuclei, and not due to thermal processing during migration into the Jupiter Family.

The oligomeric PN monomers were prepared from the reaction of an excess amount of bisphenol A with a dihalo-aliphatic containing compound in the presence of K2CO3 in dimethylsulfoxide, followed by end-capping with 4-nitrophthalonitrile in a two-step, one-pot reaction. These PN resin systems exhibited excellent viscosities for molding various shaped articles after thermal curing to yield crosslinked polymers. These polymers offered more mechanical flexibility, when compared with an all aromatic backbone, while still maintaining good thermal stability, dielectric properties, and low water absorption.

The u(s)-u(p) Hugoniot analysis yields a linear relationship under the range of particle velocity investigated, in agreement with previous simulation and experimental results. NP addition improves the mechanical properties of the composites, as reflected by the increased Young's modulus and yield strength especially in the case of shorter chain length of polymer. This is directly related to the increased shock impedance with NP volume fraction, as demonstrated by the enhanced pressure in the shocked state, slightly reduced microscopic deformation, and increased shock velocity. The layered structure with alternate soft and hard regions, with NP addition only in the hard regions, leads to significantly enhanced microscopic deformation in the soft regions. It is also important that the shock impedance difference between the soft and hard region to be large enough to facilitate the energy absorption through plastic deformation in the soft regions.

The two methods are implemented in a unified way which allows for a direct comparison of the non-conforming edge treatment. We outline the implementation details of the non-conforming direct stiffness summation algorithm for the CG method and show that the mass conservation error is similar to the DG method. Both methods conserve to machine precision, regardless of the presence of the non-conforming edges. For lower order polynomials the CG method requires additional stabilization to run for very long simulation times. We addressed this issue by using filters and/or additional artificial viscosity. The mathematical proof of mass conservation for CG with non-conforming meshes is presented in Appendix B. (C) 2015 Elsevier Inc. All rights reserved.

The encapsulation of enhanced green fluorescent protein (eGFP) and resultant confinement effect for eGFP within these nanotubes is studied via confocal microscopy. Timed release rate studies of eGFP encapsulated in LCA nanotubes and fluorescence recovery after photobleaching (FRAP) indicate that the diffusive transport of eGFP out of and/or within the nanotubes is very slow, in contrast to the rapid introduction of eGFP into the nanotubes. By encapsulating two fluorescent proteins in LCA nanotubes, eGFP and mCherry, as a fluorescence resonance energy transfer (FRET) pair, the FRET efficiencies are determined using FRET imaging microscopy at three different protein concentrations with a fixed donor-to-acceptor ratio of 1:1. Forster theory reveals that the proteins are spatially separated by 4.8-7.2 nm in distance inside these nanotubes. The biomimetic nanochannels of LCA nanotubes not only afford a confining effect on eGFP that results in enhanced chemical and thermal stability under conditions of high denaturant concentration and temperature, but also function as protein concentrators for enriching protein in the nanochannels from a diluted protein solution by up to two orders of magnitude.

From the analysis based on x-ray diffraction, Raman spectroscopy, scanning electron microscopy, and transmission electron microscopy, it has been found that the processed samples of wheat husk consisted of 2H and 3C polytypes of SiC exhibiting the nanostructure shapes. These nanostructures of silicon carbide formed from wheat husks are of technological importance for designing advance composites, applications in biotechnology, and electro-optics. The thermodynamics of the formation of SiC is discussed in terms of the rapid solid state reaction between hydrocarbons and silica on the molecular scale, which is inherently present in the wheat husks.

TI Inelastic neutron scattering cross sections for Ge-76 relevant to background in neutrinoless double-beta decay experiments SO PHYSICAL REVIEW C LA English DT Article ID DOPPLER-SHIFT ATTENUATION AB The experimental signature in searches for the neutrinoless double-beta decay of Ge-76 is a peak near 2039 keV in the spectrum. Given the low probability of the process, it is important that the background in this region be well understood. Inelastic scattering reactions with neutrons from muon-induced interactions and (alpha, n) reactions in the surrounding materials or in the detector can provide contributions to the background. We have measured the production cross sections for gamma rays from the Ge-76(n, n'gamma) reaction in the 2039-keV region at incident neutron energies up to 4.9 MeV. In addition to determining that the cross sections of a previously known 2040.7-keV gamma ray from the 3952-keV level in Ge-76 are rather small, we find that a larger contribution arises from a 2037.5-keV gamma ray which is attributed to a newly identified level at 3147 keV in Ge-76. A third contribution is also possible from another new level at 3577 keV. These results indicate that the 2039-keV region in Ge-76 neutrinoless double-beta decay searches is more complex than was previously thought. C1 [Crider, B. P.; McEllistrem, M. T.; Prados-Estevez, F.

TI PARKES RADIO SEARCHES OF FERMI GAMMA-RAY SOURCES AND MILLISECOND PULSAR DISCOVERIES SO ASTROPHYSICAL JOURNAL LA English DT Article DE gamma-rays: stars; pulsars: individual (PSR J0955-6150, PSR J1012-4235, PSR J1036-8317, PSR J1903-7051, PSR J1946-5403) ID LARGE-AREA TELESCOPE; X-RAY; SOURCE CATALOG; SPACE VELOCITIES; PSR J1227-4853; BINARY PULSARS; NEUTRON-STAR; LAT; POLARIZATION; PULSATIONS AB In a search with the Parkes radio telescope of 56 unidentified Fermi-Large Area Telescope (LAT) gamma-ray sources, we have detected 11 millisecond pulsars (MSPs), 10 of them discoveries, of which five were reported by Kerr et al. We did not detect radio pulsations from six other pulsars now known in these sources. We describe the completed survey, which included multiple observations of many targets conducted to minimize the impact of interstellar scintillation, acceleration effects in binary systems, and eclipses. We consider that 23 of the 39 remaining sources may still be viable pulsar candidates. We present timing solutions and polarimetry for five of the MSPs and gamma-ray pulsations for PSR J1903-7051 (pulsations for five others were reported in the second Fermi-LAT catalog of gamma-ray pulsars). Two of the new MSPs are isolated and five are in > 1 day circular orbits with 0.2-0.3 M. presumed white dwarf companions. PSR J0955-6150, in a 24 day orbit with a approximate to 0.25 M-circle dot companion but eccentricity of 0.11, belongs to a recently identified class of eccentric MSPs. PSR J1036-8317 is in an 8 hr binary with a > 0.14 M-circle dot companion that is probably a white dwarf. PSR J1946-5403 is in a 3 hr orbit with a > 0.02 M-circle dot companion with no evidence of radio eclipses. C1 [Camilo, F.] Columbia Univ, Columbia Astrophys Lab, New York, NY 10027 USA.

The mission objectives are primarily the observation of the oceanic mesoscales but also include coastal oceanography, global and regional sea level monitoring, data assimilation, and operational oceanography. Secondary objectives include ice sheet and inland waters monitoring. One year after launch, the results widely confirm the nominal expectations in terms of accuracy, data quality and data availability in general.Today's performances are compliant with specifications with an overall observed performance for the Sea Surface Height RMS of 3.4cm to be compared to a 4cm requirement. Some scientific examples are provided that illustrate some salient features of today's SARAL/AltiKa data with regard to standard altimetry: data availability, data accuracy at the mesoscales, data usefulness in costal area, over ice sheet, and for inland waters.

Wu, Dong Ho TI Responsivity optimization in magneto-optic sensors based on ferromagnetic materials SO APPLIED OPTICS LA English DT Article ID GARNET-FILMS; IRON GARNETS; FIELD; MAGNETIZATION AB In an effort to optimize magnetic field detection sensitivities, the Faraday responsivity vector, which determines the relationship between the Faraday rotation angle and an externally applied magnetic field, was investigated in magneto-optic sensors based on bismuth-doped iron-garnet films. Under externally applied fields, Faraday rotation is produced principally by domain rotation and domain wall motion, whose relative contributions depend on the domain geometry and the direction of laser propagation. When optically probed along a principal magnetization axis, Faraday rotation is driven by a single magnetization mechanism, and the responsivity is linearized (reduced to an effective Verdet constant). When the films are probed along an oblique angle to the principal axes, the relationship between the Faraday rotation and the external field becomes tensorial and much more complex. Although this may lead to more complicated phenomena, the interplay of domain rotation and domain wall bowing can be exploited to improve responsivity or bandwidth. A generalized model for the magnitude and direction of the responsivity vector is formulated, which gives predictions that are consistent with the experimental data. Applications to arrayed sensors and three-axis field measurements are discussed. (C) 2015 Optical Society of America C1 [Garzarella, A.; Shinn, M.

TI Simultaneous Stress and Field Control of Sustainable Switching of Ferroelectric Phases SO SCIENTIFIC REPORTS LA English DT Article ID PT SINGLE-CRYSTALS; SOLID-SOLUTIONS; PZN-PT; THERMODYNAMICS; PIEZOELECTRICS; TRANSITIONS; TITANATE; STRAIN AB In ferroelectrics, manifestation of a strong electromechanical coupling is attributed to both engineered domain morphology and phase transformations. However, realization of large sustainable and reversible strains and polarization rotation has been limited by fatigue, nonlinearity and hysteresis losses. Here, we demonstrate that large strain and polarization rotation can be generated for over 40 x 10(6) cycles with little fatigue by realization of a reversible ferroelectric-ferroelectric phase transition in [011] cut Pb(In1/2Nb1/2)O-3-Pb(Mg1/3Nb2/3)O-3-PbTiO3 (PIN-PMN-PT) relaxor ferroelectric single crystal. Direct tuning of this effect through combination of stress and applied electric field, confirmed both macroscopically and microscopically with x-ray and Raman scattering, reveals the local symmetry while sweeping through the transition with a low applied electric field (<0.2 MV/m) under mechanical stress. The observed change in local symmetry as determined by x-ray scattering confirms a proposed polarization rotation mechanism corresponding to a transition between rhombohedral and orthorhombic phases. These results shed more light onto the nature of this reversible transformation between two ferroelectric phases and advance towards the development of a wide range of ferroic and multiferroic devices.

Source data consist of the abundances of major taxonomic groups of phytoplankton derived from algal photopigments (1995-2004) and cell counts (1985-2007). Algal photopigments were measured by high-performance liquid chromatography (HPLC) and analyzed using the software CHEMTAX to determine the proportions of chlorophyll-a (chl-a) in major taxonomic groups. Cell counts determined microscopically provided species identifications, enumeration, and dimensions used to obtain proportions of cell volume (CV), plasma volume (PV), and carbon (C) in the same taxonomic groups. We drew upon these two independent data sets to take advantage of the unique strengths of each method, using comparable quantitative measures to express floral composition for the main stem bay. Spatial and temporal variability of floral composition was quantified using data aggregated by season, year, and salinity zone. Both time-series were sufficiently long to encompass the drought flood cycle with commensurate effects on inputs of freshwater and solutes. Diatoms emerged as the predominant taxonomic group, with significant contributions by dinoflagellates, cryptophytes, and cyanobacteria, depending on salinity zone and season. Our analyses revealed increased abundance of diatoms in wet years compared to long-term average (LTA) or dry years. Results are presented in the context of long-term nutrient over-enrichment of the bay, punctuated by inter-annual variability of freshwater flow that strongly affects nutrient loading, chl-a, and floral composition. Statistical analyses generated flow-adjusted diatom abundance and showed significant trends late in the time series, suggesting current and future decreases of nutrient inputs may lead to a reduction of the proportion of biomass comprised by diatoms in an increasingly diverse flora.

In this work, the poisoning of a Pt/C PEMFC cathode was probed by a trace of chlorobenzene in the air feed. Chlorobenzene inhibits the oxygen reduction reaction and causes significant cell performance loss. The performance loss is largely restored by neat air operation and potential cycling between 0.08 and 1.2 V under H-2/N-2 (anode/cathode). The analysis of emissions, in situ X-ray absorption spectroscopy, and electrochemical impedance spectra show the chlorobenzene adsorption/reaction and molecular orientation on Pt surface depend on the electrode potential. At low potentials, chlorobenzene deposits either on top of adsorbed H atoms or on the Pt surface via the benzene ring and is converted to benzene (ca. 0.1 V) or cyclohexane (ca. 0 V) upon Cl removal. At potentials higher than 0.2 V, chlorobenzene binds to Pt via the Cl atom and can be converted to benzene (less than 0.3 V) or desorbed. Cl- is created and remains in the membrane electrode assembly. Cl- binds to the Pt surface much stronger than chlorobenzene but can slowly be flushed out by liquid water.

It was determined that the proper combination of reaction time and temperature allows for the control of PbSe nanorod length and diameter and therefore control over their electronic states, as probed through absorbance and photoluminescence measurements. Similar to PbSe nanowires, nanorods display higher Stokes shifts than for spherical nanocrystals due to intrananorod diameter fluctuations.

We use a difference-in-differences identification strategy, measuring the changes over time in these outcomes following the combat loss of a medic or doctor and comparing it to the changes following the combat loss of a soldier who is not a medic or doctor. We find that overall unit deaths decrease in the five or ten days following the deaths of medical personnel in Vietnam, Korea, and the Pacific theater in World War II (WWII). In contrast, the WWII European and North African results indicate that overall unit deaths rise following medical personnel deaths. We find no relationship between medical personnel deaths and other unit deaths in Iraq and Afghanistan. For Korea and the Pacific theater of WWII, our estimates suggest unit commendation medals decrease following the deaths of medical personnel. This pattern of evidence is consistent with a model in which units often halted aggressive tactical maneuvers and reduced pursuit of their military objectives until deceased medical personnel were replaced.

Recruiting stations and recruiters are assigned monthly goals for the quantity of new recruits that may create an unintended incentive to sacrifice quality, especially towards the end of the month. Using data on the universe of Navy recruits from FY1998 to 2010, we find significant reductions in the quality of recruits towards the end of the contracting month, both in terms of pre-existing quality of recruits and in medium-term outcomes that reflect the quality of the job match.

To do so, we construct a model to explore the impact of a principal's choice among imperfect performance metrics for a military operation. In doing so, the principal must consider both the incentivizing and informational properties of the metric. We show the conditions under which uncertainty regarding the nature of the agent, as well as uncertainty regarding the operational environment, drives a metric choice that induces pathological behavior from the agent. More specifically, a poor metric choice can create an overly optimistic assessment and end up prolonging the conflict. We illustrate the model's insights in the cases of World War II and the Vietnam War. C1 [Blanken, Leo J.] Naval Postgrad Sch, Dept Def Anal, Monterey, CA 93943 USA.

TI Topological study of steady state, three dimensional flow over a backward facing step SO COMPUTERS & FLUIDS LA English DT Article DE Tornado like vortex; Three dimensional theory of separation ID EXPANSION; RATIO; WALL AB The topology and evolution of flow over a backward facing step in three dimensional channel flow is examined from creeping flow conditions up to Re = 950 with aspect ratio 1:40 and expansion ratio 1:2. Direct numerical simulations were performed via the parallel finite element code "FEM-3D". Analysis of the results is performed using the three dimensional theory of separation. Results reveal the existence of a primary spanwise vortex that emanates from the lateral wall and is present for all Reynolds numbers immediately downstream from the step. Frictional (shear) stresses along the lateral wall create multiple tornado like vortices. Another spanwise vortex along the top wall appears at Re = 400. As the Reynolds number increases, the top vortex increases both in spanwise and streamwise length and stunts the growth of the primary vortex. The downstream motion of the top vortex releases frictional stress thus destroying some critical points upstream while creating new ones downstream. Finally, at Re = 900 and 950, the primary and top vortices are twisting severely. Published by Elsevier Ltd. C1 [Liakos, Anastasios] US Naval Acad, Dept Math, Annapolis, MD 21402 USA.

In this context, a sensor network has two competing objectives: (1) maximisation of the network performance with respect to the probability of successful search for a specified upper bound on the probability of false alarms, and (2) maximisation of the network's operable life. As both sensing and communication of data consume battery energy at the sensing nodes of the sensor network, judicious use of sensing power and communication power is needed to improve the lifetime of the sensor network. This paper presents an adaptive energy management policy that will optimally allocate the available energy between sensing and communication at each sensing node to maximise the network performance subject to specified constraints. Under the assumptions of fixed total energy allocation for a sensor network operating for a specified time period, the problem is reduced to synthesis of an optimal network topology that maximises the probability of successful search (of a target) over a surveillance region. In a two-stage optimisation, a genetic algorithm-based meta-heuristic search is first used to efficiently explore the global design space, and then a local pattern search algorithm is used for convergence to an optimal solution. The results of performance optimisation are generated on a simulation test bed to validate the proposed concept. Adaptation to energy variations across the network is shown to be manifested as a change in the optimal network topology by using sensing and communication models for underwater environment. The approximate Pareto-optimal surface is obtained as a trade-off between network lifetime and probability of successful search over the surveillance region.

TI Optimal carbon capture and storage contracts using historical CO2 emissions levels SO ENERGY SYSTEMS-OPTIMIZATION MODELING SIMULATION AND ECONOMIC ASPECTS LA English DT Article ID COST AB In an effort to reduce carbon dioxide (CO2) emissions to the atmosphere, carbon capture and storage (CCS) technology has been developed to collect CO2 from emissions generators and store it underground. Recent proposed legislation would limit the volume of emissions generated from power sources, effectively requiring some sources to participate in CCS. Both emissions sources and storage operators require incentives to enter into contracts to capture excess emissions at the source, and transport and store the CO2 underground. As the level of emissions from power plants is stochastic and carryover into future time periods is expensive, we develop a newsvendor model to determine the optimal price and volume of these contracts to maximize the expected profit of the storage operator and encourage the participation of multiple emissions sources. Because the storage operator has a limit on the amount of CO2 that can be injected each month, this limit affects the allocation of the optimal contract amounts between the emitters. The distribution of emissions and relative costs of transportation also influence the optimal policy. In addition to analytical solutions, we present data-driven methods for using correlated emissions data to determine the optimal price and volume of these contracts.

Henshaw, C. Glen TI Trajectory Guidance Using Periodic Relative Orbital Motion SO JOURNAL OF GUIDANCE CONTROL AND DYNAMICS LA English DT Article AB Relative motion of one satellite about another in circular orbit, where the two objects have the same semimajor axis, is periodic in the linearized approximation. A set of orbital elements, the geometric relative orbital elements, which are an exact geometric analogy to the classical orbital elements, can be defined. The relative orbit is manifestly seen to be an ellipse or circle in apocentral coordinates, analogous to perifocal coordinates in inertial motion and different from the local-vertical local-horizontal Cartesian coordinates customarily used for analysis of relative motion problems. These provide a way to do relative motion trajectory design and guidance that stands in contrast to the use of Cartesian coordinates. Algorithms are presented for computing the delta-v and timing for impulsive maneuvers to change a single element: two that change the plane and one that changes the size of the relative orbit. The change in size is a two-maneuver transfer and uses the solution of the three-point periodic boundary value problem, also solved and presented here. This solution permits the direct computation, with no iteration or searching, of the periodic relative orbit that connects two points. Optimization to minimize fuel use can be done with a one-dimensional search. C1 [Healy, Liam M.; Henshaw, C. Glen] Naval Res Lab, Code 8233, Washington, DC 20375 USA.

TI Entropy rate defined by internal wave scattering in long-range propagation SO JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA LA English DT Article ID NORMAL-MODE AMPLITUDES; MATHEMATICAL-THEORY; SOUND-PROPAGATION; RANDOM OCEAN; STATISTICS; RAYS; COMMUNICATION; COHERENCE; STABILITY; CHAOS AB The reduction of information capacity of the ocean sound channel due to scattering by internal waves is a potential problem for acoustic communication, navigation, and remote sensing over long ranges. In spite of recent progress in research on acoustic signal scattering by random internal waves and the fact that random internal waves are ubiquitous in the world oceans, there is no clear understanding of how these waves influence data communication performance. The entropy decrease resulting from scattering by internal waves is an important measure of information loss. Here a rigorous calculation of the entropy is carried out using second moment transport theory equations with random sound-speed perturbations obeying the Garrett-Munk internal-wave model. It is shown that full-wave rate of entropy is of the same order of magnitude as the Kolmogorov-Sinai entropy and Lyapunov exponents for the relevant ray trajectories. The correspondence between full-wave and ray entropies suggests a correspondence between full-wave scattering and ray chaos near statistical saturation. The relatively small level of entropy rate during propagation through the random internal-wave field shows that scattering by internal waves is likely not an essential limitation for data rate and channel capacity.

TI Suture Technique Influences the Biomechanical Integrity of Pectoralis Major Repairs SO ORTHOPEDICS LA English DT Article ID TENDON-RUPTURE; MUSCLE; TEARS AB Pectoralis major ruptures occur in large, muscular individuals, and repair constructs may experience significant tension. Four different suture techniques were evaluated biomechanically to determine the effect of suture technique on optimizing fixation strength. Forty fresh-frozen cadaveric shoulders were repaired using endosteal buttons. The control group was repaired with #2 polyblend suture in a modified Mason-Allen stitch configuration. The triple group was repaired using the same suture and configuration, but with the addition of triple-loaded buttons. The configuration group was repaired using the same suture in a Krackow/Bunnell configuration. The tape group was repaired using 2-mm polyethylene tape and #5 polyblend suture in the Krackow/Bunnell configuration. Under cyclic loading, there was no significant difference between groups. Under load-to-failure testing, the tape group withstood a significantly greater maximum load (726.0 +/- 90.0 N) than the control and triple groups (330.2 +/- 20.2 and 400.2 +/- 35.2 N, respectively; P<.005), and similar load to the configuration group (509.9 +/- 68.6 N; P=.16). The configuration group failed via suture breakage (9/10); the other groups failed via suture pullout, in which suture pulled through tendon (26/30). Pectoralis major repair in a running, locked configuration appears to improve biomechanical performance by preventing suture pull-out. Use of a polyethylene tape construct demonstrates the potential for improved failure loads, but its role remains undefined.

CA Fermi LAT Collaboration TI Limits on dark matter annihilation signals from the Fermi LAT 4-year measurement of the isotropic gamma-ray background SO JOURNAL OF COSMOLOGY AND ASTROPARTICLE PHYSICS LA English DT Article DE gamma ray experiments; dark matter theory; dark matter experiments; dark matter simulations ID LARGE-AREA TELESCOPE; RADIO GALAXIES; GALACTIC HALO; COSMOLOGICAL PARAMETERS; MASS; RADIATION; EMISSION; MILKY; 1ST; ANISOTROPIES AB We search for evidence of dark matter (DM) annihilation in the isotropic gamma-ray background (IGRB) measured with 50 months of Fermi Large Area Telescope (LAT) observations. An improved theoretical description of the cosmological DM annihilation signal, based on two complementary techniques and assuming generic weakly interacting massive particle (WIMP) properties, renders more precise predictions compared to previous work. More specifically, we estimate the cosmologically-induced gamma-ray intensity to have an uncertainty of a factor similar to 20 in canonical setups. We consistently include both the Galactic and extragalactic signals under the same theoretical framework, and study the impact of the former on the IGRB spectrum derivation. We find no evidence for a DM signal and we set limits on the DM-induced isotropic gamma-ray signal. Our limits are competitive for DM particle masses up to tens of TeV and, indeed, are the strongest limits derived from Fermi LAT data at TeV energies. This is possible thanks to the new Fermi LAT IGRB measurement, which now extends up to an energy of 820 GeV. We quantify uncertainties in detail and show the potential this type of search offers for testing the WIMP paradigm with a complementary and truly cosmological probe of DM particle signals.

In particular, we prove a 'duality' result for mod p harmonic sums similar to (but distinct from) that for multiple zeta values. We also exploit the Hopf algebra structure of the quasi-symmetric functions to perform calculations with multiple harmonic sums mod p, and obtain, for each weight n through nine, a set of generators for the space of weight-n multiple harmonic sums mod p. When combined with recent work, the results of this paper offer significant evidence that the number of quantities needed to generate the weight-n multiple harmonic sums mod p is the nth Padovan number (OEIS sequence A000931).

The interest in this problem is motivated by numerous observations of magnetic oscillations with frequencies in the range of 0.1-4.0Hz detected on the ground at low and middle latitudes. In a number of studies these oscillations interpreted as shear Alfven waves standing inside the so-called ionospheric Alfven resonator. We present results from two-dimensional, time-dependent simulations of the reduced two-fluid MHD model performed in the dipole magnetic field geometry with the realistic parameters of the magnetospheric plasma. These simulations show that these pulsations can be produced by the fundamental mode of the global field line resonator, spanning the entire magnetic field line in the low or middle magnetosphere. Simulations also show that even the waves with the highest considered frequencies (2.44Hz) are not trapped inside the ionospheric resonator. Therefore, if these waves will be generated by some ionospheric source, then they can reach the equatorial magnetosphere and interact with energetic protons in the proton radiation belt.

The aim of this work was to compare the V. harveyi CAIM 1792 genome with related genome sequences to determine their phylogenic relationship and explore unique regions in silico that differentiate this strain from other V. harveyi strains. Twenty-one newly sequenced genomes were compared in silico against the CAIM 1792 genome at nucleotidic and predicted proteome levels. The proteome of CAIM 1792 had higher similarity to those of other V. harveyi strains (78 %) than to those of the other closely related species Vibrio owensii (67 %), Vibrio rotiferianus (63 %) and Vibrio campbellii (59 %). Pan-genome ORFans trees showed the best fit with the accepted phylogeny based on DNA DNA hybridization and multi-locus sequence analysis of 11 concatenated housekeeping genes. SNP analysis clustered 34/38 genomes within their accepted species. The pangenomic and SNP trees showed that V. harveyi is the most conserved of the four species studied and V. campbellii may be divided into at least three subspecies, supported by intergenomic distance analysis. BLASTP atlases were created to identify unique regions among the genomes most related to V. harveyi CAIM 1792; these regions included genes encoding glycosyltransferases, specific type restriction modification systems and a transcriptional regulator, LysR, reported to be involved in virulence, metabolism, quorum sensing and motility.

TI A New Look at Type-III Bursts and Their Use as Coronal Diagnostics SO SOLAR PHYSICS LA English DT Article DE Corona, radio emission; Radio bursts, dynamic spectrum; Radio bursts, type III; Waves, plasma ID SOLAR RADIO-BURSTS; SPATIAL VARIATIONS; ELECTRON; TEMPERATURES; BEAMS AB We present meter-wave solar radio spectra of the highest spectro-temporal resolution achieved to date. The observations, obtained with the first station of the Long Wavelength Array (LWA1), show unprecedented detail of solar emissions across a wide bandwidth during a Type-III/IIIb storm. Our flux calibration demonstrates that the LWA1 can detect Type-III bursts much weaker than 1 SFU, much lower than previous observations, and that the distribution of fluxes in these bursts varies with frequency. The high sensitivity and low noise in the data provide strong constraints to models of this type of plasma emission, providing evidence against the idea that Type-IIIb striae are generated from electrons trapped in Langmuir-wave sidebands. The continuous generation of electron beams in the corona revealed by the high density Type-III storm is evidence for ubiquitous magnetic reconnection in the lower corona. Such an abundance of reconnection events not only contributes to the total coronal energy budget, but also provides an engine by which to form the populations of seed particles responsible for proton-rich solar energetic-particle events. An active region (AR) with such levels of reconnection and the accompanying Type-III/IIIb storms is proposed here to be associated with an increase of SEP production if a CME erupts. The data's constraints on existing theories of Type-IIIb production are used to make an association of the observed Type-IIIb storm to specific electron-beam paths with increased inhomogeneities in density, temperature, and/or turbulence. This scenario ties in the observed timing of Type-III and -IIIb storms, constrained theories of Type-III and -IIIb emission, and the ability of the emitting AR to produce a strong SEP event. The result requires but a single observable to cement these ideas, the statistical correlation of Type-III/IIIb activity with SEP-productive AR. C1 [Beltran, Samuel D.

Using data from the Solar-Terrestrial Environment Laboratory, Japan, these reconstructions provide a real-time prediction of the global solar-wind density and velocity throughout the whole heliosphere with a temporal cadence of about one day ips.ucsd.edu . Updates to this modeling effort continue: in the present article, near-Sun results extracted from the time-dependent 3D reconstruction are used as inner boundary conditions to drive 3D-MHD models (e.g. ENLIL and H3D-MHD). This allows us to explore the differences between the IPS kinematic-model data-fitting procedure and current 3D-MHD modeling techniques. The differences in these techniques provide interesting insights into the physical principles governing the expulsion of coronal mass ejections (CMEs). Here we detail for the first time several specific CMEs and an induced shock that occurred in September 2011 that demonstrate some of the issues resulting from these analyses.

TI SAMI3/SD-WACCM-X simulations of ionospheric variability during northern winter 2009 SO SPACE WEATHER-THE INTERNATIONAL JOURNAL OF RESEARCH AND APPLICATIONS LA English DT Article DE ionospheric modeling; lower atmospheric coupling; SSW ID LOWER THERMOSPHERE; SEASONAL-VARIATION; DIURNAL TIDE; WACCM-X; ATMOSPHERE; MODEL; MESOSPHERE; WAVE; GCM AB We have performed simulations using the Naval Research Laboratory's physics-based model of the ionosphere, Sami3 is A Model of the Ionosphere (SAMI3), to illustrate how neutral wind dynamics is responsible for day-to-day variability of the ionosphere. We have used neutral winds specified from the extended version of the specified dynamics Whole Atmosphere Community Climate Model (SD-WACCM-X), in which meteorology below 92km is constrained by atmospheric specifications from an operational weather forecast model and reanalysis. To assess the realism of the simulations against observations, we have carried out a case study during January-February 2009, a dynamically disturbed time characterized by a sudden stratospheric warming (SSW) commencing 24 January 2009. Model results are compared with total electron content (TEC) from Jet Propulsion Laboratory global ionospheric maps. We show that SAMI3/SD-WACCM-X captures longitudinal variability in the equatorial ionization anomaly associated with nonmigrating tides, with strongest contributions coming from the diurnal eastward wave number 2 (DE2) and DE3. Both migrating and nonmigrating tides contribute to significant day-to-day variability, with TEC varying up to 16%. Our simulation during the SSW period reveals that at the Jicamarca longitude (285 degrees E) on 27 January 2009 nonmigrating tides contribute to an enhancement of the electron density in the morning followed by a decrease in the afternoon. An enhancement of the semidiurnal eastward wave number 2 (SE2) and SE3 nonmigrating tides, likely associated with the appearance of the SSW, suggests that these tides increase the longitudinal variability of the SSW impact on the ionosphere. The conclusion is that realistic meteorology propagating upward from the lower atmosphere influences the dynamo region and reproduces aspects of the observed variability in the ionosphere.

We used a zero-one integer program to partition 58 donor service areas into between four and eight sharing districts that minimize the disparity in liver availability among districts. Because the integer program necessarily suppressed clinically significant differences among patients and organs, we tested the optimized district maps with a discrete-event simulation tool that represents liver allocation at a per-person, per-organ level of detail. In April 2014, the liver committee of the Organ Procurement and Transplantation Network (OPTN) decided in a unanimous vote of 22-0-0 to write a policy proposal based on our eight-district and four-district maps. The OPTN board of directors could implement the policy after the proposal and public-comment period. Redistricting liver allocation would save hundreds of lives over the next five years and would attenuate the serious geographic inequity in liver transplant offers.

We nominally define the hurricane boundary layer as the layer in which the effects of surface friction are associated with significant departures from gradient wind balance. The boundary layer in the intensifying primary and forming secondary eyewalls is found to be nonlinear. At large radii, exterior to the eyewalls, Ekman-like balance as traditionally defined, is found to hold true. Where significant departures from Ekman-like balance are found, the departures are characterized by large vertical advection of horizontal velocity through the depth of the boundary layer. Shock-like structures are not found to be prominent in the azimuthally averaged view of the vortex boundary layer, with the largest azimuthally averaged radial gradients of the radial and tangential velocities being on the order of only a few meters per second per kilometer. Also, in the radial regions of the eyewalls, at the height where the averaged tangential wind is a maximum, the radial advection of radial velocity is an order of magnitude smaller than the agradient force per unit mass. Some physical implications of these findings are discussed. C1 [Abarca, Sergio F.] NOAA NWS NCEP, IMSG, College Pk, MD 20740 USA. [Montgomery, Michael T.] Naval Postgrad Sch, Monterey, CA USA.

The study addresses three outstanding basic questions concerning the effects of moist convection on the azimuthal flow asymmetries and provides a bridge between the problem of tropical cyclone intensification in a quiescent environment and that in vertical shear over a deep tropospheric layer. At any instant of time, explicit deep convection in the model generates flow asymmetries that tend to mask the induced flow asymmetries predicted by the dry, slab boundary layer model of Shapiro, whose results are frequently invoked as a benchmark for characterizing the boundary layer-induced vertical motion for a translating storm. In sets of ensemble experiments in which the initial low-level moisture field is randomly perturbed, time-averaged ensemble mean fields in the mature stage show a coherent asymmetry in the vertical motion rising into the eyewall and in the total (horizontal) wind speed just above the boundary layer. The maximum ascent occurs about 45 degrees to the left of the vortex motion vector, broadly in support of Shapiro's results, in which it occurs ahead of the storm, and consistent with one earlier more complex numerical calculation by Frank and Ritchie. The total wind asymmetry just above the boundary layer has a maximum in the forward right sector, which is in contrast to the structure effectively prescribed by Shapiro based on an inviscid dry symmetric vortex translating in a uniform flow where, in an Earth-relative frame, the maximum is on the right.

TI Indirect evidence for substantial damping of low-mode internal tides in the open ocean SO JOURNAL OF GEOPHYSICAL RESEARCH-OCEANS LA English DT Article DE internal tide damping; internal tide dissipation ID GENERAL-CIRCULATION MODEL; DEEP-OCEAN; HAWAIIAN RIDGE; TIDAL ENERGY; KAENA RIDGE; SURFACE MANIFESTATION; VERTICAL COORDINATE; CONTINENTAL-SLOPE; BAROCLINIC TIDES; GLOBAL PATTERNS AB A global high-resolution ocean circulation model forced by atmospheric fields and the M-2 tidal constituent is used to explore plausible scenarios for the damping of low-mode internal tides. The plausibility of different damping scenarios is tested by comparing the modeled barotropic tides with TPXO8, a highly accurate satellite-altimetry-constrained tide model, and by comparing the modeled coherent baroclinic tide amplitudes against along-track altimetry. Five scenarios are tested: (1) a topographic internal wave drag, argued here to represent the breaking of unresolved high vertical modes, applied to the bottom flow (default configuration), (2) a wave drag applied to the barotropic flow, (3) absence of wave drag, (4) a substantial increase in quadratic bottom friction along the continental shelves (with wave drag turned off), and (5) application of wave drag to the barotropic flow at the same time that quadratic bottom friction is substantially increased along the shelves. Of the scenarios tested here, the default configuration (1) yields the most accurate tides. In all other scenarios (2-5), the lack of damping on open ocean baroclinic motions yields baroclinic tides that are too energetic and travel too far from their sources, despite the presence of a vigorous mesoscale eddy field which can scatter and decohere internal tides in the model. The barotropic tides are also less accurate in the absence of an open ocean damping on barotropic motions, that is, in scenarios (3) and (4). The results presented here suggest that low-mode internal tides experience substantial damping in the open ocean.

TI Impact of Deck and Jet Blast Deflector on the Flow and Acoustic Properties of an Imperfectly Expanded Supersonic Jet SO NAVAL ENGINEERS JOURNAL LA English DT Article ID FLUX-CORRECTED TRANSPORT; ALGORITHMS; TURBULENCE; EQUATIONS; EULER; FCT AB The impact of a model aircraft carrier deck and jet blast deflector (JBD) has been investigated using a recently developed flow code JENRE (the Jet Engine Noise Reduction) at an underexpanded jet condition. The agreement of the computed flow and near-field acoustic properties of the baseline configuration (without the carrier deck and JBD) agree well with available experimental data. It is found that the deck surface, which is 1.6 D (D is the nozzle exit diameter) below the jet centerline, and a JBD surface, which is roughly 6.0 D downstream of the end of the potential core, have little impact on the shock-cell structure and jet potential core. However, the deck reflection increases the near-field noise levels and the magnitude of this increase grows with the axial distance up to the location roughly 5.0 D downstream of the jet potential core. It is found that the increase of the noise level caused by the deck reflection is predominantly in the high-frequency components. The JBD surface redirects both the jet plume and the pressure waves generated by the jet plume to the upward direction relative to the JBD surface. The trailing edges of the JBD surface also generate pressure waves that propagate in both upstream and downstream directions and interact with pressure waves generated by the jet plume. The JBD surface increases the noise level in the low-frequency range upstream of the JBD location, indicating that the trailing edge effect is the main cause of this increase.

The catalyst for this project was a new ship class requirement to have an Unrep system that could deliver current system loads at twice the speed or twice as heavy loads at current systems speeds, Heavy E-STREAM (Electronic-Standard Tensioned REplenishment Alongside Method). Legacy technologies proved to be ineffectual for these difficult requirements while modern components and electronic controls proved highly capable to solve this complex at-sea, intership cargo transfer system. Obsolescence and maintenance issues with the legacy system, along with demonstrated performance gains and proposed engineering improvements reducing Total Ownership Costs (TOC) of this new system, led to the sponsor tasking development of two additional Unrep systems, one fuel and one cargo. These systems would be designed with legacy capability, utilizing the controls developed during the Heavy E-STREAM, maximizing any development work put into reducing TOC, and would become the Navy's new Standard Unrep system. These two new systems are E-STREAM Fueling-At-Sea (E-FAS) and E-STREAM Cargo (E-RAS - E-STREAM Replenishment-At-Sea). The following paper discusses why and how the system was modernized, how the new design will decrease maintenance requirements, both preventative and corrective, and what the current status is of the system development.

TI Review of wave-turbulence interactions in the stable atmospheric boundary layer SO REVIEWS OF GEOPHYSICS LA English DT Review DE waves; turbulence; wave-turbulence interaction; atmospheric boundary layer; stably stratifed flows ID INTERNAL GRAVITY-WAVES; KELVIN-HELMHOLTZ BILLOWS; STRATIFIED SHEAR FLOWS; ONE CRITICAL-LEVEL; MONOTONIC VELOCITY PROFILE; CRITICAL RICHARDSON-NUMBER; SCALE ELIMINATION MODEL; TETHERED LIFTING SYSTEM; DIRECTIONAL WIND SHEAR; ANTARCTIC ICE SHELF AB Flow in a stably stratified environment is characterized by anisotropic and intermittent turbulence and wavelike motions of varying amplitudes and periods. Understanding turbulence intermittency and wave-turbulence interactions in a stably stratified flow remains a challenging issue in geosciences including planetary atmospheres and oceans. The stable atmospheric boundary layer (SABL) commonly occurs when the ground surface is cooled by longwave radiation emission such as at night over land surfaces, or even daytime over snow and ice surfaces, and when warm air is advected over cold surfaces. Intermittent turbulence intensification in the SABL impacts human activities and weather variability, yet it cannot be generated in state-of-the-art numerical forecast models. This failure is mainly due to a lack of understanding of the physical mechanisms for seemingly random turbulence generation in a stably stratified flow, in which wave-turbulence interaction is a potential mechanism for turbulence intermittency. A workshop on wave-turbulence interactions in the SABL addressed the current understanding and challenges of wave-turbulence interactions and the role of wavelike motions in contributing to anisotropic and intermittent turbulence from the perspectives of theory, observations, and numerical parameterization. There have been a number of reviews on waves, and a few on turbulence in stably stratified flows, but not much on wave-turbulence interactions. This review focuses on the nocturnal SABL; however, the discussions here on intermittent turbulence and wave-turbulence interactions in stably stratified flows underscore important issues in stably stratified geophysical dynamics in general.

The water surface and the bed were imaged simultaneously to create time-dependent maps of the water surface velocities and the bed elevations that can be used to validate numerical models at high spatial and temporal resolution. The technique was applied in a sandy meander bend at the University of Minnesota Saint Anthony Falls Laboratory Outdoor StreamLab. The root mean square differences between optical estimates of the bed and in situ observations ranged between 0.01 and 0.03 m. Mean bed form wavelength was 0.73 m and mean crest height was 0.07 m, but both varied with distance around the meander bend. Bed form classification varied with distance downstream, and sinuosity of bed forms varied with local radius of curvature. Bed form roughness scaled similarly to other natural riverine environments although wavelength and height magnitude and variability were larger than predicted by empirical formulations for straight reaches. Bed form translation rate varied between 1 and 5 mm s(-1). Estimates of velocity from particle image velocimetry (PIV) on the water surface were approximate to 10% higher than in situ observations collected approximate to 0.05 m below the water surface. Using the PIV observations to drive simple equations for bed load sediment flux, we explained up to 72% of the observed variance in downstream sediment flux. The new methodology described here provides nonintrusive, high spatial and temporal resolution measurements of both the bed and the flow.

High proton yield emitted to narrow solid angle with energies of up 25 MeV were detected from interaction of a 5 TW laser with snow targets. The high yield was attributed to a carefully planned prepulse and microstructured snow targets. We studied experimentally the minimal energy requirements for the adequate prepulse and we are using PIC simulations to study the dynamics of acceleration process. Based on our simulations, we predict that using the proposed scheme protons can be accelerated to energies above 150 MeV by 100 TW laser systems.

Two second language (L2) Spanish participants and three L2 English participants carried out a six-week e-mail exchange that centered on specific holidays, giving researchers an opportunity to study participants' intercultural communicative competence (ICC) (Byram, 1997) and how participants critically analyzed and discussed cultural aspects of an L2 language (Klein & Solem, 2008). Participants' exchanges revealed the following: (1) each participant's thoughts on his/her partner's culture as was perceived through L2 instruction, (2) each partner's reaction to perceptions and insight to cultural reality, and (3) sharing of personal anecdotes. Patterns in exchanges were analyzed using NVivo 10 software with a data-driven, hybrid analytical approach. Thematic categories were created from the data and used to code the e-mail exchanges and subsequently correlated to Helm and Guth's (2010) framework. Results indicated that participants using a Web 1.0 resource experienced transformation through the telecollaboration. Researchers concluded that more nuanced categories were needed to assess ICC to understand the intricacies of online collaborative exchanges. Researchers believed that Web 1.0, in the absence of Web 2.0, remained a valuable venue for telecollaboration.

The first generation super dielectric materials (SDM) are multi-material mixtures with dielectric constants greater than 1.0 x 10(5), composed of a porous, electrically insulating powder filled with a polarizable, ion-containing liquid. Second-generation SDMs (TSDM), introduced here, are anodic titania nanotube arrays filled with concentrated aqueous salt solutions. Capacitors using TiO2 based TSDM were found to have dielectric constants at similar to 0 Hz greater than 10(7) in all cases, a maximum operating voltage of greater than 2 volts and remarkable energy density that surpasses the highest previously reported for EC capacitors by approximately one order of magnitude. A simple model based on the classic ponderable media model was shown to be largely consistent with data from nine EC type capacitors employing TSDM.

How these electrons are transported and heat the plasma are crucial questions for laser fusion. This paper works out a Fokker Planck and Krook theory for such transport and heating. The result is a set of equations, for which one can find a simple asymptotic approximation for the solution, for the Fokker Planck case, and an exact solution for the Krook case. These solutions are evaluated and compared with one another. They give rise to expressions for the spatially dependent heating of the background plasma, as a function of the instantaneous laser and plasma parameters, in either planar or spherical geometry. These formulas are simple, universal (depending weakly only on the single parameter Z, the charge state), and can be easily be incorporated into a fluid simulation. (C) 2015 AIP Publishing LLC.

Predominantly electrostatic waves in the whistler branch are launched that propagate near the resonance cone with measured wave normal angle greater than 85 degrees. When the pump amplitude exceeds a threshold similar to 5 x 10(-6) times the background magnetic field, wave power at frequencies below the pump frequency is observed at wave normal angles (similar to 55 degrees). The scattered wave has a perpendicular wavelength that is nearly an order of magnitude larger than that of the pump wave. Occasionally, the parametric decay of a lower hybrid wave into a magnetosonic wave and a whistler wave is simultaneously observed with a threshold of delta B/B-0 similar to 7 x 10(-7).

As a control, T. scotoductus cells were also cultured using convection heating at the same temperature as the MW studies. Cell growth was analyzed by optical density (OD) measurements, and cell morphologies were characterized using electron microscopy imaging (scanning electron microscopy [SEM] and transmission electron microscopy [TEM]), dynamic light scattering (DLS), and atomic force microscopy (AFM). Biophysical properties (i.e., turgor pressure) were also calculated with AFM, and biochemical compositions (i.e., proteins, nucleic acids, fatty acids) were analyzed by attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy. Gas chromatography-mass spectrometry (GC-MS) was used to analyze the fatty acid methyl esters extracted from cell membranes. Here we report successful cultivation of a thermophile with only dielectric heating. Under the MW conditions for growth, cell walls remained intact and there were no indications of membrane damage or cell leakage. Results from these studies also demonstrated that T. scotoductus cells grown with MW heating exhibited accelerated growth rates in addition to altered cell morphologies and biochemical compositions compared with oven-grown cells.

We start with our own discovery of the phenomenon, but go on to establish the historical timeline of this topic back to the earliest known paper. The topic of synchronization of chaotic systems has always been intriguing, since chaotic systems are known to resist synchronization because of their positive Lyapunov exponents. The convergence of the two systems to identical trajectories is a surprise. We show how people originally thought about this process and how the concept of synchronization changed over the years to a more geometric view using synchronization manifolds. We also show that building synchronizing systems leads naturally to engineering more complex systems whose constituents are chaotic, but which can be tuned to output various chaotic signals. We finally end up at a topic that is still in very active exploration today and that is synchronization of dynamical systems in networks of oscillators. (C) 2015 Author(s).

TI Asymmetric turbulent boundary layers along long thin circular cylinders at low-Re SO PHYSICS OF FLUIDS LA English DT Article ID WALL-PRESSURE-FLUCTUATIONS; AXIAL-FLOW; FLAT-PLATE; SIMULATIONS; WAKE AB Notable deviations of the asymmetric turbulent boundary layer (TBL) statistics from their axisymmetric counterpart along long thin circular cylinders are vitally important to the naval and oceanographic jurisdictions. Although the available experimental evidence backs their concern, the realm of parametric variability (both geometric and kinematic) is extremely limited to draw solid conclusions. We know that only small misalignments which quantify less than one degree of incidence between the freestream and the straight cylinder axis can substantially alter the boundary layer thicknesses, mean axial velocity, and Reynolds stresses. But the statistical database is plainly inadequate to justify modifying the design tools that were founded solely for axisymmetric flow conditions. Herein, we begin rectifying this drawback by numerical means. The investigation centers on low turbulent Reynolds numbers (500 <= Re-a <= 2500) and small angles-of-incidence (0 degrees < alpha < 9 degrees) to validate and complement the lions-share of the present database (Re-a = aU(o)/v, where a, U-o, and. are the cylinder radius, freestream velocity, and kinematic viscosity, respectively). In particular, we numerically resolved the statistical responses of the TBL, mean axial velocity, Reynolds stresses, and skin friction under angles-of-incidence up to the earliest signs of Strouhal-type shedding. Clearly, the first prominent response was the thinning and thickening of the TBL along the respective windward and leeward sides to only a minor misalignment. Tilting the straight cylinder to slightly higher yaw angles transformed the TBL to a transitional boundary layer along the windward side for all simulated Reynolds numbers. For yaw angles alpha > 2 degrees, all turbulent statistics of the asymmetric boundary layer were measurably dissimilar to those of the axisymmetric state.

TI Screens versus microarrays for ruggedized retarding potential analyzers SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article ID ION; TEMPERATURE; ERRORS AB An array of highly miniaturized electrostatic lenses is shown to be a viable replacement for meshes or screens in a retarding potential analyzer (RPA) where mechanical ruggedness or the ability to intercept large currents of energetic particles is desirable. Data from a prototype device are presented cross-calibrated with a traditional planar RPA indicating how the so-called microarray configuration avoids energy-dependent transparency (either reduced or enhanced) associated with meshes or screens while providing accurate energy analysis with reasonable energy resolution. In contrast, another ruggedized configuration employing a screen is presented, showing the severity of energy-dependent enhanced transparency, verified by numerical simulation. C1 [Enloe, C.

IPC-2014 was held in three separate parts to assess the state of the art in three prominent areas of planning research: the deterministic (classical) part (IPCD), the learning part (IPCL), and the probabilistic part (IPPC). Each part evaluated planning systems in ways that pushed the edge of existing planner performance by introducing new challenges, novel tasks, or both. The competition surpassed again the number of competitors that participated in its predecessor, highlighting the competition's central role in shaping the landscape of ongoing developments in evaluating planning systems.

TI THE THIRD CATALOG OF ACTIVE GALACTIC NUCLEI DETECTED BY THE FERMI LARGE AREA TELESCOPE SO ASTROPHYSICAL JOURNAL LA English DT Article DE BL Lacertae objects: general; galaxies: active; galaxies: jets; gamma rays: galaxies ID GAMMA-RAY EMISSION; ALL-SKY SURVEY; EXTRAGALACTIC BACKGROUND LIGHT; SPECTRUM RADIO QUASARS; GALAXY 3C 111; X-RAY; COMPLETE SAMPLE; OPTICAL IDENTIFICATIONS; PARTICLE-ACCELERATION; RELATIVISTIC JETS AB The third catalog of active galactic nuclei (AGNs) detected by the Fermi-LAT (3LAC) is presented. It is based on the third Fermi-LAT catalog (3FGL) of sources detected between 100 MeV and 300 GeV with a Test Statistic greater than 25, between 2008 August 4 and 2012 July 31. The 3LAC includes 1591 AGNs located at high Galactic latitudes (vertical bar b vertical bar > 10 degrees), a 71% increase over the second catalog based on 2 years of data. There are 28 duplicate associations, thus 1563 of the 2192 high-latitude gamma-ray sources of the 3FGL catalog are AGNs. Most of them (98%) are blazars. About half of the newly detected blazars are of unknown type, i.e., they lack spectroscopic information of sufficient quality to determine the strength of their emission lines. Based on their gamma-ray spectral properties, these sources are evenly split between flat-spectrum radio quasars (FSRQs) and BL Lacs. The most abundant detected BL Lacs are of the high-synchrotron-peaked (HSP) type. About 50% of the BL Lacs have no measured redshifts. A few new rare outliers (HSP-FSRQs and high-luminosity HSP BL Lacs) are reported. The general properties of the 3LAC sample confirm previous findings from earlier catalogs. The fraction of 3LAC blazars in the total population of blazars listed in BZCAT remains non-negligible even at the faint ends of the BZCAT-blazar radio, optical, and X-ray flux distributions, which hints that even the faintest known blazars could eventually shine in gamma-rays at LAT-detection levels. The energy-flux distributions of the different blazar populations are in good agreement with extrapolation from earlier catalogs.

Staphylococcus spp. (n = 10) and a variety of Gram-negative isolates (n = 21) were taken from a larger collection of wound isolates collected during 2011-2013 and were analysed for the presence of >230 resistance determinants using a broad-spectrum DNA microarray. These isolates were chosen to represent the species most commonly found in wound isolates referred during this time and to include some of the most resistant strains. Resistance determinants detected among the staphylococci included blaZ (90%), mecA (100%), erm(B) (70%), erm(C) (20%), tet(38) (90%), tet(K) (40%), tet(L-p) (10%), tet(M) (20%), Inu(A)/lin(A) and Inu(B)/lin(B) (10% each), msr(A)/msr(B)/msr(SA) (10%), norA (80%) and dfrA (10%). Eleven different beta-lactamase genes were detected among the Gram-negative bacteria, including genes encoding the TEM (48%), CTX-M-1 (48%), CTX-M-9 (5%), SHV (5%) and VEB (10%) families of broad-spectrum and extended-spectrum beta-lactamase enzymes, as well as the carbapenemase gene bla(OXA-23). Forty additional genes were also detected in the Gram-negative isolates conferring resistance to aminoglycosides (11 genes), phenicols (5 genes), macrolides [4 genes, including mph(A)/mph(K) (10%)], lincosamides [Inu(F)Ilin(F), Inu(G)Ilin(G)1, tetracycline (4 genes), rifampicin [arr (29%)], quaternary amines [qacE Delta 1 (43%)], quinolones [qnrS (14%) and qnrB (5%)], sulfonamides [sul1 (29%), sul2 (38%) and sul3 (10%)], streptothricin (sat2) and trimethoprim (6 genes). The results obtained here provide a snapshot of the broad variety of resistance determinants currently circulating within Cambodia.

TI ConfChem Conference on Flipped Classroom: Time-Saving Resources Aligned with Cognitive Science To Help Instructors SO JOURNAL OF CHEMICAL EDUCATION LA English DT Article DE General Public; High School/Introductory Chemistry; First-Year Undergraduate/General; Curriculum; Problem Solving/Decision Making Learning Theories AB Studies in cognitive science have verified that working memory (where the brain solves problems) can manipulate nearly all elements of knowledge that can be recalled automatically from long-term memory, but only a few elements that have not previously been well memorized. Research in reading comprehension has found that "lecture notes with clicker questions" can move a portion of lecture content to homework. By applying these findings to the design of homework-tutorials for students, under the right conditions, we found that time for active learning during lecture increased and student achievement measurably improved. Factors that have affected the outcome of our experiments are discussed. This communication summarizes one of the invited papers to the ConfChem online conference Flipped Classroom, held from May 9 to June 12, 2014 and hosted by the ACS DivCHED Committee on Computers in Chemical Education (CCCE).

For this reason multiple companies have designed traps to specifically target those species. Recently the standard trap for DENV and CHIKV vectors, the BG-Sentinel (BGS) trap, has been remodeled to be more durable and better suited for use in harsh field conditions, common during military operations, and relabeled the BG-Sentinel 2 (BGS2). This new trap was evaluated against the standard Centers for Disease Control and Prevention (CDC) light trap, Zumba Trap, and BG-Mosquitito Trap to determine relative effectiveness in collecting adult Aedes aegypti and Ae. albopictus. Evaluations were conducted under semifield and field conditions in suburban areas in northeastern Florida from May to August 2014. The BGS2 trap collected more DENV and CHIKV vectors than the standard CDC light trap, Zumba Trap, and BG-Mosquitito Trap, but attracted fewer species, while the BG-Mosquitito Trap attracted the greatest number of mosquito species.

TI Growth and optimization of InxGayAl1-x-ySb buffer layers for electronic and optoelectronic applications SO JOURNAL OF VACUUM SCIENCE & TECHNOLOGY B LA English DT Article ID COMPOUND SEMICONDUCTORS; TRANSISTORS; SUBSTRATE; DEVICES; DIODES; GASB AB In(x)GayAl(1-x-y)Sb alloys have been grown by molecular beam epitaxy for use as a buffer layer for growing semiconductors on GaAs substrates with lattice constants beyond that of AlSb. This is an extension of the use of In(x)GayAl(1-x-y)Sb alloys to accommodate for the lattice mismatch with semi-insulating GaAs substrates. The growth of In0.21Ga0.19Al0.6Sb with a 6.2 angstrom lattice constant on semi-insulating GaAs substrates is the focus of this work. Several measures of the quality of a 1 mu m-thick In0.21Ga0.19Al0.6Sb layer improved when the growth temperature was increased from 460 to 600 degrees C. Atomic force microscopy root-mean-square values decreased from 2.9 to 1.8 nm and the peak-to-valley values decreased from 17.7 to 9.7 nm. In addition, double crystal x-ray diffraction omega-2 Theta spectra linewidths decreased from 568 to 482 arc sec. At the lower growth temperatures, several photoluminescence (PL) peaks associated with radiative recombination from regions with different alloy compositions were found. However, on increasing the growth temperature a single PL line was observed, strongly suggesting a more uniform alloy composition.

TI Formation of nanometer-thick delaminated amorphous carbon layer by two-step plasma processing of methacrylate-based polymer SO JOURNAL OF VACUUM SCIENCE & TECHNOLOGY B LA English DT Article ID VACUUM-ULTRAVIOLET RADIATION; 193 NM PHOTORESIST; ION-BOMBARDMENT; CROSS-LINKING; PMMA; CHEMISTRY; RESIST AB The authors show that extended He plasma pretreatment (PPT) of methacrylate-based 193 nm photoresist (PR) material in conjunction with a subsequent biased Ar plasma treatment can lead to blister formation at the polymer surface due to delamination of an ultrathin, ion-induced, dense, amorphous carbon (DAC) layer formed by low energy ion bombardment. For our experimental conditions, the delaminated layer is 1-2 nm thick and primarily composed of sp(2)-hybrized amorphous carbon. A He or Ar plasma process alone will not lead to this phenomenon, and so far the authors have only observed it for a methacrylate polymer. A possible mechanism of the formation of the ultrathin layer that is consistent with all observations is as follows: During He plasma pretreatment, volatile species are produced by ultraviolet/vacuum ultraviolet radiation-induced photolysis of the polymer pendant groups, e.g., adamantyl and chain-scissioning of the polymer backbone to a depth of greater than 100 nm. While volatile products formed close to the polymer surface can diffuse out during He PPT, those formed deep within the polymer bulk cannot and their concentration will become significant for extended He PPT. During the biased Ar plasma treatment step, a DAC surface layer is generated by Ar+ ion bombardment within the first seconds of plasma exposure. The thickness is dependent on ion energy and in the range of one to several nanometers. This layer appears to be impermeable to gaseous products formed in the PR material. Thus, volatile species diffusing to the surface can accumulate underneath the DAC layer, causing a loss of adhesion and subsequent delamination of this layer from the PR bulk film. The authors also report surface and electrical characterizations of the ultrathin DAC layer using optical microscopy, transmission electron microscopy, Raman and x-ray photoemission spectroscopy, and two-point probe techniques.

TI Effect of Interface Interaction on the Segmental Dynamics of Poly(vinyl acetate) Investigated by Local Dielectric Spectroscopy SO ACS MACRO LETTERS LA English DT Article ID THIN POLYMER-FILMS; GLASS-TRANSITION TEMPERATURE; FORCE MICROSCOPY; BULK BEHAVIOR; T-G; CONFINEMENT; NANOSCALE; RELAXATION; LIQUIDS; DEVIATIONS AB The segmental dynamics of poly(vinyl acetate) (PVAc) thin films were measured in the presence of an aluminum interface and in contact with an incompatible polymer, poly(4-vinylpyridine). The local dielectric relaxation was found to be faster in thin films than in the bulk; however, no differences were observed for the various interfaces, including a PVAc/air interface. These results show that capping of thin films, even with a rigid material, does not necessarily affect the dynamics, the speeding up herein for capped PVAc was equivalent to that for the air interface. The insensitivity of the dynamics to the nature of the interface affords a means to engineer thin films while maintaining desired mechanical properties. Our findings for PVAc also may explain the discordant results that have been reported in general for the effect of air versus rigid interfaces on the local segmental relaxation of thin films.

Two ratiometric quantum dot (QD) Forster resonance energy transfer-based sensors designed to monitor the activity of the proteolytic enzymes collagenase and elastase are investigated here. Given the unique material constraints of these sensing constructs, assays are realized utilizing excess enzyme and fixed substrate in progress curve format to yield enzyme specificity or k (cat)/K (m) ratios. The range of k (cat)/K-m values derived is 0.5-1.1 mM(-1) s(-1) for the collagenase sensor and 3.7-4.2 mM(-1) s(-1) for the elastase sensor. Of greater interest is the observation that the elastase sensor can be well represented by the Michaelis-Menten model while the collagenase sensor cannot. The latter demonstrates increased specificity at higher peptide substrate/QD loading values and an apparent QD-caused reversible inhibition as the reaction progresses. Understanding the detailed kinetic mechanisms that underpin these types of sensors will be important especially for their further quantitative utilization.

Previous researches showed differential expression of genes when entomopathogenic fungi are cultured in insect or plant materials. However, so far there is no report on metabolic alterations of B. bassiana in the environments of insect or plant. The purpose of this paper is to address this problem. Herein, we first provide the metabolomic analysis of B. bassiana cultured in insect pupae extracts (derived from Euproctis pseudoconspersa and Bombyx mori, EPP and BMP), plant root exudates (derived from asparagus and carrot, ARE and CRE), distilled water and minimal media (MM), respectively. Principal components analysis (PCA) shows that mycelia cultured in pupae extracts and root exudates are evidently separated and individually separated from MM, which indicates that fungus accommodates to insect and plant environments by different metabolic regulation mechanisms. Subsequently, orthogonal projection on latent structure-discriminant analysis (OPLS-DA) identifies differential metabolites in fungus under three environments relative to MM. Hierarchical clustering analysis (HCA) is performed to cluster compounds based on biochemical relationships, showing that sphingolipids are increased in BMP but are decreased in EPP. This observation further implies that sphingolipid metabolism may be involved in the adaptation of fungus to different hosts. In the meantime, sphingolipids are significantly decreased in root exudates but they are not decreased in distilled water, suggesting that some components of the root exudates can suppress sphingolipid to down-regulate sphingolipid metabolism. Pathway analysis finds that fatty acid metabolism is maintained at high level but non-ribosomal peptides (NRP) synthesis is unaffected in mycelia cultured in pupae extracts. In contrast, fatty acid metabolism is not changed but NRP synthesis is high in mycelia cultured in root exudates and distilled water. This indicates that fungal fatty acid metabolism is enhanced when contacting insect, but when in the absence of insect hosts NRP synthesis is increased. Ornithine, arginine and GABA are decreased in mycelia cultured in pupae extracts and root exudates but remain unchanged in distilled water, which suggests that they may be associated with fungal cross-talk with insects and plants. Trehalose and mannitol are decreased while adenine is increased in three conditions, signifying carbon shortage in cells. Together, these results unveil that B. bassiana has differential metabolic responses in pupae extracts and root exudates, and metabolic similarity in root exudates and distilled water is possibly due to the lack of insect components.

TI Optical Filter Selection for High Confidence Discrimination of Strongly Overlapping Infrared Chemical Spectra SO ANALYTICAL CHEMISTRY LA English DT Article ID INDUCED BREAKDOWN SPECTROSCOPY; PATTERN-RECOGNITION; PREDICTIVE SPECTROSCOPY; EXPLOSIVES DETECTION; STANDOFF DETECTION; IDENTIFICATION; DESIGN; CLASSIFICATION; KROMOSCOPY; RESIDUES AB Optical filter-based chemical sensing techniques provide a new avenue to develop low-cost infrared sensors. These methods utilize multiple infrared optical filters to selectively measure different response functions for various chemicals, dependent on each chemical's infrared absorption. Rather than identifying distinct spectral features, which can then be used to determine the identity of a target chemical, optical filter-based approaches rely on measuring differences in the ensemble response between la given filter set and specific chemicals of interest. Therefore, the results of such methods are highly dependent on the original optical filter choice, which will dictate the selectivity, sensitivity, and stability of any filter-based sensing method, Recently, a method has been developed that utilizes unique detection vector operations defined by optical multifilter responses, to discriminate between volatile chemical vapors. This method, comparative-discrimination spectral detection (CDSD), is a technique Which employs broadband optical filters to selectively discriminate between chemicals with highly overlapping infrared absorption spectra. CDSD has been shown to correctly distinguish between similar chemicals in the carbon hydrogen stretch region of the infrared absorption spectra from 2800-3100 cm(-1). A key challenge to this approach is how to determine Which optical filter sets should be utilized to achieve the greatest discrimination between target chemicals. Previous studies used empirical approaches to select the optical filter set; however this is insufficient to determine the optimum selectivity between strongly overlapping chemical spectra. Here we present a numerical approach to systematically study the effects of filter positioning and bandwidth on a number of three-chemical systems. We describe how both the filter properties, as well as the chemicals in each set, affect the CDSD results and subsequent discrimination. These results demonstrate the importance of choosing the proper filter set and chemicals for comparative discrimination, in order to identify the target chemical of interest in the presence of closely matched chemical interferents. These findings are an integral step in the development of experimental prototype sensors, which will utilize CDSD.

Exactly 475 nightmares and 433 unpleasant dreams were collected from Dreamboard users, while 135 nightmares were collected from individuals who reported having recurrent nightmares via a SurveyMonkey survey. Results demonstrated that physical aggression and anxiety levels were significantly higher for nightmares from individuals who reported recurrent nightmares relative to nightmares from people not reporting recurrent nightmares who in turn reported nightmares, which evidenced higher physical aggression levels relative to unpleasant dreams. Use of personal pronouns, verbs, and social terms were significantly reduced in recurrent nightmares relative to regular nightmares and unpleasant dreams. Aggressors were most often supernatural agents in recurrent nightmares; unfamiliar males in regular nightmares and familiar males in unpleasant dreams. Physical aggression against the dreamer was the most common theme in nightmares while interpersonal conflict was the most common theme in unpleasant dreams. Nightmares associated with awakenings evidenced significantly higher levels of aggression relative to nightmares not associated with awakenings. People with recurrent nightmares were 3 times more likely to report a relative on their maternal side with recurrent nightmares. We conclude that levels of physical aggression within the dream and targeted against the dreamer distinguishes recurrent from nonrecurrent nightmares and unpleasant dreams.

Iodine's nutrient-like behavior and the source-specificity of I-131 make this radionuclide a potentially valuable tracer in wastewater nitrogen studies. Iodine-I-131 was measured in Potomac River water and sediments in the vicinity of the Blue Plains WPCP, Washington, DC, USA. Dissolved I-131 showed a strong, positive correlation with delta N-15 values of nitrate (delta(NO3-)-N-15) in the river, the latter being a traditional indicator of nutrient inputs and recycling. Surface water delta(NO3-)-N-15 values ranged from 8.7 to 33.4 parts per thousand; NO3- + NO2- concentrations were 0.39-2.79 mg N L-1 (26-186 mu M). Sediment profiles of particulate I-131 and delta N-15 indicate rapid mixing or sedimentation and in many cases remineralization Of a heavy nitrogen source consistent with wastewater nitrogen. Values of delta N-15 in sediments ranged from 4.7 to 9.3 parts per thousand. This work introduces I-131 as a tool to investigate the short-term fate of wastewater nitrogen in the Potomac River and demonstrates the general utility of I-131 in aquatic research.

Principal findings of the relationship between Delta SD and the MJO included the following: 1) Statistically significant regions of lagged Delta SD anomalies for multiple phases of the MJO were found in March, April, and May in both North America and Eurasia. 2) In each month, lagged Delta SD anomalies were physically supported by corresponding lagged anomalies of 500-hPa height (Z500) and surface air temperature (SAT). Spearman rank correlation coefficients indicated a moderate to strong relationship between both Z500 and Delta SD and SAT and Delta SD in both Eurasia and North America for phases 5 and 7 in March. In April, a moderately strong relationship between Z500 and Delta SD was found over Eurasia for phase 5, but the relationship between SAT and Delta SD was weak. In May, correlations between Delta SD and both Z500 and SAT over a hemisphere-wide latitude band from 60 degrees to 75 degrees N were close to -0.5 and -0.4, respectively. Given the strength of these statistical relationships, the following physical pathway is proposed for intraseasonal variability of spring snow depth changes: poleward-propagating Rossby waves in response to tropical MJO convection interact with Northern Hemisphere background flow, leading to anomalous troughing and ridging. These anomalous circulation centers then impact daily snow depth change via precipitation processes and anomalies in surface air temperature.

TI Future Flood Frequency under Sea-Level Rise Scenarios SO JOURNAL OF COASTAL RESEARCH LA English DT Article DE Sea-level rise acceleration; storm surge; statistics AB The effect of sea-level rise (SLR) on exceedance probabilities for annual flooding at coastal locations is explored in this paper. We assess four future SLR scenarios given by the U.S. Army Corps of Engineers and how these SLR scenarios affect monthly flooding statistics. Focusing on one case site, Annapolis, Maryland, we fit the probability density function of the monthly maximum tide gauge record with a Pareto-tail distribution. Random sampling from this distribution is then performed on top of the various future SLR scenarios. Exceedance probabilities for a storm tide to exceed the coastal flood stage, the elevation of which has already been established in a previous paper, are then calculated from the interpolated Pareto cumulative distribution. We illustrate that even mild increases in mean sea level acceleration lead to drastically higher exceedance probabilities of coastal flooding.

TI Field Observations of Surf Zone-Inner Shelf Exchange on a Rip-Channeled Beach SO JOURNAL OF PHYSICAL OCEANOGRAPHY LA English DT Article ID VERTICAL STRUCTURE; SOUTHERN CALIFORNIA; FINITE DEPTH; WAVE-DRIVEN; CURRENTS; UNDERTOW; FLOW; TRANSPORT; DRIFTERS; MOTIONS AB Cross-shore exchange between the surf zone and the inner shelf is investigated using Lagrangian and Eulerian field measurements of rip current flows on a rip-channeled beach in Sand City, California. Surface drifters released on the inner shelf during weak wind conditions moved seaward due to rip current pulses and then returned shoreward in an arcing pattern, reentering the surf zone over shoals. The cross-shore velocities of the seaward- and shoreward-moving drifters were approximately equal in magnitude and decreased as a function of distance offshore. The drifters carried seaward by the rip current had maximum cross-shore velocities as they exited the surf zone and then decelerated as they moved offshore. The drifters moving shoreward accelerated as they approached the surfzone boundary with maximum cross-shore velocities as they reentered the surf zone over shoals. It was found that Stokes drift was not solely responsible for the onshore transport across the surfzone boundary. The cross-shore diffusivity on the inner shelf was greatest during observations of locally contained cross-shore exchange. These field observations provide evidence that the cross-shore exchange between the surf zone and inner shelf on a rip-channeled beach is due to wave-driven rip current circulations and results in surface material being contained within the nearshore region.

A 2-way multivariate analysis of variance (MANOVA) was conducted to explore the relationship of hardiness dimensions on several psychological and physical factors. Compared with other military samples, this cohort reported similar levels on hardiness control and rigidity subscales. Recruits who reported higher scores on a measure of positive hardiness also reported higher scores on measures of grit, grit ambition, sensation seeking, training expectations, positive ways of coping, physical and mental health, fitness scores, and lower scores on a measure of depression. This study provides a more complete understanding of the complex array of attributes of Marine recruits and forms a foundation for predictive models of injury risk and/or attrition.

Bis-oximes contain two oxime groups connected by a hydrophobic linker. One oxime group of Ortho-7 binds at the entrance to the active-site gorge near Trp279, and the second binds at the bottom near Trp84 and Phe330. In the Ortho-7-TcAChE complex the oxime at the bottom of the gorge was directed towards the nucleophilic Ser200. In contrast, the oxime group of 2BIM-7 was rotated away from Ser200 and the oxime at the entrance induced a significant conformational change in the peripheral anionic site (PAS) residue Trp279. The conformational change alters the surface of the PAS and positions the imidazolium oxime of 2BIM-7 further from Ser200. The relatively weaker binding and poorer reactivation of VXinhibited, tabun-inhibited or sarin-inhibited human acetylcholinesterase by 2BIM-7 compared with Ortho-7 may in part be owing to the unproductively bound states caught in crystallo. Overall, the reactivation efficiency of 2BIM-7 was comparable to that of 2-pyridine aldoxime methyl chloride (2-PAM), but unlike 2-PAM the bis-imidazolium oxime lacks a fixed charge, which may affect its membrane permeability.

The oligomeric phthalonitrile monomer is prepared from the reaction of an excess amount of bisphenol A with 4-(chlorophenyl)sulfone in the presence of a mixed base system (NaOH/K2CO3) in a dimethylsulfoxide/toluene solvent mixture, followed by end-capping with 4-nitrophthalonitrile in a two-step, one-pot reaction. This phthalonitrile resin exhibits lower viscosities than previously reported systems for molding into various shapes. After being thermally cured to yield crosslinked polymers, this sulfonyl-based polymer demonstrates superb mechanical properties and thermo-oxidative stability, absorbs less than 1.0 weight percent water, and maintains good dielectric properties.

The thermal stability and their thermal expansion coefficients were investigated up to 1000 degrees C using in situ X-ray diffraction. No phase transitions were observed in these samples up to 1000 degrees C. Volume thermal expansion coefficients for the hexagonal and monoclinic phases of bulk Gd2-xInxO3 for x=0.5 and 1.0 showed increasing trend in comparison to the end compound of In2O3. The inverse susceptibility measurements between 300 and 5K showed the linear relationship with temperature consistent with the Curie-Weiss law. The Weis constants were small and negative, indicating a slight degree of anti-ferromagnetic exchange between cations and consistent with the absence of magnetic order down to 5K. C1 [Qadri, S.

TI The STEP Model: Characterizing Simultaneous Time Effects on Practice for Flight Simulator Performance Among Middle-Aged and Older Pilots SO PSYCHOLOGY AND AGING LA English DT Article DE practice effects; age; expertise; real-world performance ID INTRAINDIVIDUAL VARIABILITY; COGNITIVE-ABILITY; EXPERTISE; SKILLS; SELECTION; ADULTS; TESTS AB Understanding the possible effects of the number of practice sessions (practice) and time between practice sessions (interval) among middle-aged and older adults in real-world tasks has important implications for skill maintenance. Prior training and cognitive ability may impact practice and interval effects on real-world tasks. In this study, we took advantage of existing practice data from 5 simulated flights among 263 middle-aged and older pilots with varying levels of flight expertise (defined by U.S. Federal Aviation Administration proficiency ratings). We developed a new Simultaneous Time Effects on Practice (STEP) model: (a) to model the simultaneous effects of practice and interval on performance of the 5 flights, and (b) to examine the effects of selected covariates (i.e., age, flight expertise, and 3 composite measures of cognitive ability). The STEP model demonstrated consistent positive practice effects, negative interval effects, and predicted covariate effects. Age negatively moderated the beneficial effects of practice. Additionally, cognitive processing speed and intraindividual variability (IIV) in processing speed moderated the benefits of practice and/or the negative influence of interval for particular flight performance measures. Expertise did not interact with practice or interval. Results indicated that practice and interval effects occur in simulated flight tasks. However, processing speed and IIV may influence these effects, even among high-functioning adults. Results have implications for the design and assessment of training interventions targeted at middle-aged and older adults for complex real-world tasks.

The learning-based classifiers achieve the state-of-the-art accuracies, but have been criticized for the computational complexity that grows linearly with the number of classes. The nonparametric nearest neighbor (NN)-based classifiers naturally handle large numbers of categories, but incur prohibitively expensive computation and memory costs. In this brief, we present a novel classification scheme, i.e., discriminative hierarchical K-means tree (D-HKTree), which combines the advantages of both learning-based and NN-based classifiers. The complexity of the D-HKTree only grows sublinearly with the number of categories, which is much better than the recent hierarchical support vector machines-based methods. The memory requirement is the order of magnitude less than the recent Na ve Bayesian NN-based approaches. The proposed D-HKTree classification scheme is evaluated on several challenging benchmark databases and achieves the state-of-the-art accuracies, while with significantly lower computation cost and memory requirement.

The structural evolution of deep convection through the life cycle of the ERC was clearly evident in the radial variation of positive water vapor (WV) minus infrared (IR) brightness temperature differences over the 96-h period. Within this framework, the ERC was divided into six broadly defined stages, wherein convective processes (including eyewall development and decay) were analyzed and then validated using microwave data. Dual maxima in aircraft wind speeds and geostationary satellite BTs along flight transects through Sinlaku were used to document the temporal evolution of the ERC within the TC inner core. Negative correlations were found between IR BTs and surface wind speeds, indicating that colder cloud tops were associated with stronger surface winds. Spatial lags indicated that the strongest surface winds were located radially inward of both the flight-level winds and coldest cloud tops. Finally, timing of the ERC was observed equally in IR and WV minus IR (WVIR) BTs with one exception. Decay of the inner eyewall was detected earlier in the WVIR data. These findings highlight the potential utility of WVIR and IR BT radial profiles, particularly so for basins without active aircraft weather reconnaissance programs such as the western North Pacific.

In moist air, the rate of hydrogen entry may control crack growth rates. X-ray photoelectron spectroscopy showed that the oxide formed in ambient conditions (e.g. similar to 50% RH) was more hydrated on the AA7075-T651 than AA7079-T651. (C) 2015 Elsevier Ltd.

Haloperidol has been shown to be effective for migraine treatment. Study Objective: Our study compared the use of metoclopramide vs. haloperidol to treat ED migraine patients. Methods: A prospective, double-blinded, randomized control trial of 64 adults aged 18-50 years with migraine headache and no recognized risks for QT-prolongation. Haloperidol 5 mg or metoclopramide 10 mg was given intravenously after 25 mg diphenhydramine. Pain, nausea, restlessness (akathisia), and sedation were assessed with 100-mm visual analog scales (VAS) at baseline and every 20 min, to a maximum of 80 min. The need for rescue medications, side effects, and subject satisfaction were recorded. QTc intervals were measured prior to and after treatment. Follow-upcalls after 48 h assessed satisfaction and recurrent or persistent symptoms. Results: Thirty-one subjects received haloperidol, 33 metoclopramide. The groups were similar on all VAS measurements, side effects, and in their satisfaction with therapy. Pain relief averaged 53 mm VASoverbothgroups, with equal times to maximumim provement. Subjects receiving haloperidol required rescuemedication significantly less often (3% vs. 24%, p < 0.02). MeanQTcs were equal and normal in the two groups and did not change after treatment. In telephone follow-up, 90% of subjects contacted were "happy with the medication'' they had received, with haloperidol-treated subjects experiencing more restlessness (43% vs. 10%). Conclusions: Intravenous haloperidol is as safe and effective as metoclopramide for the ED treatment of migraine headaches, with less frequent need for rescue medications. Published by Elsevier Inc.

US military members from the Millennium Cohort Study deployed in support of the recent operations were followed for approximately 7 years from baseline through 2 follow-up periods between 2001 and 2008. Propensity score matching was used to match 1 male to each female using demographic, military, and behavioral factors including baseline sexual assault. Analyses were stratified by combat experience defined as reporting at least one of five exposures during follow-up. Outcome measures included a positive screen for PTSD and severity scores measured by the PTSD Patient Checklist Civilian Version. Discrete-time survival analysis quantified the association between gender and incident PTSD. Among 4684 matched subjects (2342 women and men), 6.7% of women and 6.1% of men developed PTSD during follow-up. Results showed no significant gender differences for the likelihood of developing PTSD or for PTSD severity scores among women and men who reported combat experience and among those who did not. This study is the first of its kind to match a large population of male and female service members on important baseline characteristics including sexual assault. Findings suggest that while combat deployed personnel develop PTSD, women do not have a significantly different risk for developing PTSD than men after experiencing combat. Published by Elsevier Ltd.

In this review, we first survey techniques for measuring thermospheric density, empirical models that provide a synthesis of historical data, and physical models that simulate the environment by solving fluid equations. We then review the climate and weather features that are observed in thermospheric density (including its response to solar forcing) and summarize recent studies of these features. The review is focused on results published between 2000 and 2014, which coincides with a period of extensive accelerometer measurements of density and accompanying research; some historical context is also provided.

A retrospective cohort study was conducted to evaluate the association between spousal deployment and postpartum depression among pregnant wives of active-duty service members. Electronic medical records for 161,454 births occurring between 2004 and 2009 were used to define postpartum depression. Three non-mutually exclusive exposure variables were created to categorize deployments as occurring before, during, or after the infant's delivery. A multivariable logistic regression model mutually adjusted for these exposure variables was fitted, producing an odds ratio for each of the three timing categories. A modest significant association was detected only in those whose husbands deployed in pregnancy and returned after delivery (i.e., deployed during delivery) [odds ratio (OR) 1.10, 95 % confidence interval (CI) 1.04-1.15]. An interactive effect between preexisting depression or anxiety and deployment during delivery was also detected in the data (OR 1.13, 95 % CI 1.07-1.20 for those without a preexisting diagnosis; OR 0.87, 95 % CI 0.80-0.95 for those with a preexisting diagnosis). Health care providers should continue to be aware of spousal deployment as a military-unique stressor in this population and rigorously screen for potential symptoms of postpartum depression, especially among those whose husbands are absent at delivery.

Schiller/Goethe; Kafka's hybrid duality; Noah's Ark ID 'BERICHT-FUR-EINE-AKADEMIE'; FREEDOM AB This paper explores the key concept of 'Ruhe' in "A Report to an Academy" (1917), essential for an understanding of its inception and Kafka's spiritual ties to the Christian and Greek tradition. While Kafka scholarship has already made some reference to Schiller's irony and typological writing "On Naive and Sentimental Poetry" (1795), it has yet to recognize Kafka's poetic appropriation of Goethe's observing mode of 'Ruhe' as narrative mode. The entertaining variety show acts, along with making the ape's philosophical reflections on his mortifying cage experience evident to the critical eye, help create a streaming gaze that morphs all activities and gestures into simple human rituals. The ship (a modern version of Noah's Ark), a microcosm of human society, entails in embryo all elements that will shape the ape's life on the continent after achieving a certain degree of 'humanity.' The report culminates in a drinking parody of Goethe's theoretical writing "Simple Imitation, Manner, Style" (1789), depicting the ape's breakthrough and ascension to human and academic status through language. In this new light the report humorously manifests Kafka's defiance of Goethe's literary authority while, at the same time, paying an homage to ancient classicism.

However, to our knowledge, the influence of this body of work has not been evaluated bibliometrically, and doing so is important to determine the modern impact of combat casualty research in the wider medical community. Questions/purposes We sought to identify the 20 most commonly cited works from military surgeons published during the Iraq and Afghanistan conflicts and analyze them to answer the following questions: (1) What were the subject areas of these 20 articles and what was the 2013 Impact Factor of each journal that published them? (2) How many citations did they receive and what were the characteristics of the journals that cited them? (3) Do the citation analysis results obtained from Google Scholar mirror the results obtained from Thompson-Reuters' Web of Science? Methods We searched the Web of Science Citation Index Expanded for relevant original research performed by US military orthopaedic surgeons related to Operation Iraqi Freedom and Operation Enduring Freedom between 2001 and 2014. Articles citing these studies were reviewed using both Web of Science and Google Scholar data. The 20 most cited articles meeting inclusion criteria were identified and analyzed by content domain, frequency of citation, and sources in which they were cited. Results Nine of these studies examined the epidemiology and outcome of combat injury. Six studies dealt with wound management, wound dehiscence, and formation of heterotopic ossification. Five studies examined infectious complications of combat trauma. The median number of citations garnered by these 20 articles was 41 (range, 28-264) in Web of Science. Other research citing these studies has appeared in 279 different journals, covering 26 different medical and surgical subspecialties, from authors in 31 different countries. Google Scholar contained 97% of the Web of Science citations, but also had 31 duplicate entries and 29 citations with defective links. Conclusions Modern combat casualty research by military orthopaedic surgeons is widely cited by researchers in a diverse range of subspecialties and geographic locales. This suggests that the military continues to be a source of innovation that is broadly applicable to civilian medical and surgical practice and should encourage expansion of military-civilian collaboration to maximize the utility of the knowledge gained in the treatment of war trauma.

Consistent with recently published results, we show that the early onset of the NH PMC season in 2013 was accompanied by a warm springtime stratosphere; conversely, we show that the late onset in 2008 coincides with a very cold springtime stratosphere. Similar stratospheric temperature anomalies for 1997 and 2011 also are connected either directly, through observed temperatures, or indirectly, through an early PMC onset, to conditions near the mesopause. These 4 years, 2008, 1997, 2011, and 2013 represent the extremes of stratospheric springtime temperatures seen in the MERRA analysis and correspond to analogous extrema in planetary wave activity. The three years with enhanced planetary wave activity (1997, 2011 and 2013) are shown to coincide with the recently identified stratospheric Frozen In Anticyclone (FrIAC) phenomenon. FrIACs in 1997 and 2013 are associated with early PMC onsets; however, the dramatic FrIAC of 2011 is not. This may be because the 2011 FrIAC occurred too early in the spring. The link between NH PMC onset and stratospheric FrIAC occurrences represents a new mode of coupling between the stratosphere and mesosphere. Since FrIACs appear to be more frequent in recent years, we speculate that as a result, PMCs may occur earlier as well. Finally we compare the zonal mean zonal winds and observed gravity wave activity for the FrIACs of 2011 and 2013. We find no evidence that gravity wave activity was favored in 2013 relative to 2011, thus suggesting that direct forcing by planetary waves was the key mechanism in accelerating the cooling and moistening of the NH mesopause region in May of 2013.

Russell, James M., III TI The influence of PMCs on water vapor and drivers behind PMC variability from SOFIE observations SO JOURNAL OF ATMOSPHERIC AND SOLAR-TERRESTRIAL PHYSICS LA English DT Article DE Polar mesospheric cloud; PMC; SOFIE; AIM; SBUV ID POLAR MESOSPHERIC CLOUDS; SUMMER MESOSPHERE; TEMPERATURE AB Observations from the Solar Occultation For Ice Experiment (SOFIE) are used to quantify relationships between polar mesospheric clouds (PMC) and their environment. Dehydration due to ice growth is found to be greatest similar to 1.8 km above the height of peak ice mass density on average, and H2O enhancement due to sublimation is greatest near the bottom of the PMC layer. The dehydration and hydration layers contain a similar amount of H2O, although less than is found in ice layers, a difference that may be due to meridional transport. Because PMCs modify the surrounding water vapor, PMC-H2O relationships can be misleading and recommendations are made for dealing with this issue. The dependence of PMCs on water vapor and temperature was quantified, accounting for the effects of ice on water vapor. The approach examined inter-annual variations and considered the subset of PMCs detected by the Solar Backscatter Ultraviolet (SBUV) instruments, which are less sensitive than SOFIE. Results in the Northern Hemisphere indicate that PMC variations are dominated by temperature, but that a combination of temperature and water vapor provides the best explanation of the observations. In the Southern Hemisphere PMC variability is attributed primarily to temperature, with water vapor playing a minor role. The subset of SBUV PMCs are found to be one third as sensitive to changing temperature as the entire PMC population observed by SOFIE. Finally, an approach is presented which allows temperature and water vapor anomalies to be estimated from various PMC data sets such as SBUV. Using recently reported SBUV PMC trends at 64-74 degrees N latitude with the results of this study indicates a cooling trend of -0.27 +/- 0.14 K decade(-1) and a water vapor increase of +0.66 +/- 0.34% decade(-1) (both at 80-84 km). This cooling trend agrees with reports based on observations in the middle atmosphere at similar latitudes. The water vapor increase is lower than expected due to increasing methane, although this difference may be consistent with H2O loss due to photolysis at PMC altitudes. (C) 2015 Elsevier Ltd.

The OHP has dimensions of 1.3 cm thick, 22.9 cm long, and 7.6 cm wide embedded with two-independent closed-loops forming three layers of channels. The OHP was directly clamped to a railgun system in a medium caliber launcher (MCL) and subjected to high current electric discharges occurring over several microseconds. The experimental results show that the OHP is capable of significantly reducing peak temperatures during a pulsed heating event over pure copper, even in the presence of relatively high magnetic fields.

Kevin TI The Value of Recovery Transformers in Protecting an Electric Transmission Grid Against Attack SO IEEE TRANSACTIONS ON POWER SYSTEMS LA English DT Article DE Power system modeling; restoration and protection; security; substations; transformers ID TERRORIST THREAT; POWER-SYSTEMS; INTERDICTION; SECURITY AB This paper incorporates, as part of an attacker-defender (AD) model for an electric power transmission grid, an inventory of "recovery spares" for high-voltage transformers (HVTs). In this sequential-game model, an attacker first uses limited resources to disable grid components, seeking to maximize second-stage "total cost." This value corresponds to a defender who operates the damaged grid to minimize generating and economic load-shedding costs. The defender's problem includes 1) optimal power-flow solutions to represent post-attack operations, 2) optimized replacement of disabled HVTs with quickly installable recovery spares, and 3) longer-term replacements using new procurements. Global Benders decomposition, with a mixed-integer subproblem, solves the AD model; new enumerative techniques help solve the decomposition's master problem and subproblems. Computational tests demonstrate tradeoffs between the number of recovery spares and worst-case total cost, and show how the model could help guide an inventory strategy for recovery spares in an adversarial setting.

In particular, we are focusing on the associated structural and physical behaviors of the melts of different cross-linking degree under Couette and Poiseuille flow conditions. At the nanoscale, we also investigated the stress, heat flux and temperature fields that are computable from the quantities of the coarse-grained model of the epoxy resin melt with the extended Hardy's theory to multibody potentials. We have established that the epoxy resin chains tend to reorient along the direction of the imposed Couette flow, and the degree of alignment increases with the cross-linking degree and shear rate. The pronounced reorientation of cross-linked epoxy resin melts can be ascribed to the inter-bonded chains. This conformational change explains the shear thinning behaviors of cross-linked melts that initiate at low shear rates. The cross-linked melts under Poiseuille flow possess less pronounced velocity profiles, accompanied with the smaller temperature rise from the applied gravity force. Due to the size of the nanoscale channel height, the epoxy resin melts under Poiseuille flow can only be approximately predicted via the continuum theory. We have shown that the discrepancies between atomistic simulations and continuum predictions increase as the wall/epoxy interaction strength reduces. This study reveals the variations of important rheological properties during the cross-linking process and elucidates the roles played by the topological changes in the shear flow, thus can contribute to the design and manufacturing of the epoxy-resin based nanocomposites.

Indium and aluminum fluxes were varied independently at substrate temperatures below and above the onset of thermal desorption of indium. At low temperatures, the InAIN composition and growth rate are determined by the group-Ill fluxes. With increasing substrate temperature, the surface morphology transitions from quasi-3D to a smooth, 20 morphology at temperatures significantly above the onset of indium loss. At higher temperatures, we observe increased indium evaporation with higher indium fluxes and a suppression of indium evaporation with increased aluminum flux. The final optimized InAIN thin film results in step-flow morphology with rms roughness of 0.19 nm and high interfacial quality. (C) 2015 Elsevier B.V. All rights reserved. C1 [Hardy, M.

A power-series expansion of the subaperture phase history data is applied to compute a generic expression for the down-range and cross-range components of the predicted central 2-D contour of mover signatures, including the cross-range offset. In addition, the current analysis generates an analytic approximation for the 2-D impulse response (IPR) of surface moving target signatures within subaperture images. This investigation reveals that the summation of a large number of nonoverlapping IPRs yields an excellent reproduction of the target signature, including smear width and self-interference effects, as compared with standard image formation using simulated radar data. Thus, the analytics derived herein can provide an effective methodology for understanding the shape, extent, location, width, and interference effects of smears due to arbitrarily moving surface targets for squinted spotlight SAR.

Kosta, Marek TI Constructing a single cell in cylindrical algebraic decomposition SO JOURNAL OF SYMBOLIC COMPUTATION LA English DT Article DE Cylindrical algebraic decomposition; Projection operator; Polynomial constraints AB This paper presents an algorithm which, given a point and a set of polynomials, constructs a single cylindrical cell containing the point, such that the given polynomials are sign-invariant in the computed cell. To represent a single cylindrical cell, a novel data structure is introduced. The algorithm works with this representation and proceeds incrementally, i.e., first constructing a cell representing the whole real space, and then iterating over the input polynomials, refining the cell at each step to ensure the sign-invariance of the current input polynomial. A merge procedure realizing this refinement is described, and its correctness is proven. The merge procedure is based on McCallum's projection operator, but uses geometric information relative to the input point to reduce the number of projection polynomials computed. The use of McCallum's operator implies the incompleteness of the algorithm in general. However, the algorithm is complete for well-oriented sets of polynomials. Moreover, the incremental approach described in this paper can be easily adapted to a different projection operator. The cell construction algorithm presented in this paper is an alternative to the "model-based" method described by jovanovie and de Moura in a 2012 paper. It generalizes the algorithm described by the first author in a 2013 paper, which could only produce full-dimensional cells, to allow for the construction of cells of arbitrary dimension. While a thorough comparison, whether analytical or empirical, of the new algorithm and the "modelbased" approach will be the subject of future work, this paper provides preliminary justification for asserting the superiority of the new method.

The composition of these ternaries was intentionally varied through alterations in the cycle ratios of the III-nitride binary layers (AlN, GaN, and InN). By this digital alloy growth method, we are able to grow III-nitride ternaries by PA-ALE over nearly the entire stoichiometry range including in the spinodal decomposition region (x = 15-85%). These early efforts suggest great promise of PA-ALE at low temperatures for addressing miscibility gap challenges encountered with conventional growth methods and realizing high performance optoelectronic and electronic devices involving ternary/binary heterojunctions, which are not currently possible.

The RuO2 nanoskins are disordered and exhibit lower conductivity than polycrystalline sputtered RuO2 films but are more optically transmissive: similar to 1.6 k Omega sheet resistance and 80% transmission at 800 nm for a 10-nm-thick nanoskin. Ruthenia nanoskins are promising transparent conducting coatings because they are easy to fabricate and provide a chemically versatile, conformal film that is highly transmissive over a broad spectral region suitable for spectroelectrochemical studies. Due primarily to their lower absorption, the real component (epsilon(1)) of the complex permittivity epsilon for the RuO2 nanoskins is positive over the entire spectral region investigated (0.6-4.5 eV) whereas it is negative for the sputtered films, consistent with their metallic character. The imaginary component (epsilon(2)) of the complex permittivity places disordered RuO2 in the ranks of less "lossy" conductors, but its low epsilon(1) ensures that this form of the oxide cannot be plasmonic in the optical window.

TI Effective field enhancement factor and the influence of emitted space charge SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID ELECTRON-EMISSION; CARBON NANOTUBES; CATHODES; MODELS AB Although Fowler and Nordheim developed the basics of field emission nearly one century ago with their introduction of the Fowler-Nordheim equation (FNE), the topic continues to attract research interest particularly with the development of new materials that have been proposed as field emitters. The first order analysis of experiments typically relies upon the FNE for at minimum a basic understand of the physical emission process and its parameters of emission. The three key parameters in the FNE are the work function, emission area, and field enhancement factor, all of which can be difficult to determine under experimental conditions. This paper focuses in particular, on the field enhancement factor beta. It is generally understood that b provides an indication of the surface roughness or sharpness of a field emitter cathode. However, in this paper, we experimentally and computationally demonstrate that cathodes with highly similar surface morphologies can manifest quite different field enhancements solely through having different emission regions. This fact can cause one to re-interpret results in which a single sharp emitter is proposed to dominate the emission from a field emitting cathode. (C) 2015 AIP Publishing LLC.

Microporous and mesoporous carbon structures are computationally generated using liquid quench method and reactive force fields. Motivated by the need to understand high temperature diffusivity of light weight gases like H-2, O-2, H2O, and CO in amorphous carbon, we investigate the diffusion behavior as function of two important parameters: (a) the pore size and (b) the concentration of diffusing gases. The effect of pore size on diffusion is studied by employing multiple realizations of the amorphous carbon structures in microporous and mesoporous regimes, corresponding to densities of 1 g/cm(3) and 0.5 g/cm(3), respectively. A detailed analysis of the effect of gas concentration on diffusion in the context of these two porosity regimes is presented. For the microporous structure, we observe that predominantly, a high diffusivity results when the structure is highly anisotropic and contains wide channels between the pores. On the other hand, when the structure is highly homogeneous, significant molecule-wall scattering leads to a nearly concentration-independent behavior of diffusion (reminiscent of Knudsen diffusion). The mesoporous regime is similar in behavior to the highly diffusive microporous carbon case in that diffusion at high concentration is governed by gas-gas collisions (reminiscent of Fickian diffusion), which transitions to a Knudsen-like diffusion at lower concentration.

TI Comparison of co-located independent ground-based middle atmospheric wind and temperature measurements with numerical weather prediction models SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article ID LOW-TOP VERSIONS; RESEARCH SATELLITE; DATA ASSIMILATION; ROCKETSONDE WIND; SURFACE CLIMATE; GRAVITY-WAVES; VARIABILITY; THERMOSPHERE; STRATOSPHERE; SIMULATIONS AB High-resolution, ground-based and independent observations including co-located wind radiometer, lidar stations, and infrasound instruments are used to evaluate the accuracy of general circulation models and data-constrained assimilation systems in the middle atmosphere at northern hemisphere midlatitudes. Systematic comparisons between observations, the European Centre for Medium-Range Weather Forecasts (ECMWF) operational analyses including the recent Integrated Forecast System cycles 38r1 and 38r2, the NASA's Modern-Era Retrospective Analysis for Research and Applications (MERRA) reanalyses, and the free-running climate Max Planck Institute-Earth System Model-Low Resolution (MPI-ESM-LR) are carried out in both temporal and spectral domains. We find that ECMWF and MERRA are broadly consistent with lidar and wind radiometer measurements up to similar to 40 km. For both temperature and horizontal wind components, deviations increase with altitude as the assimilated observations become sparser. Between 40 and 60km altitude, the standard deviation of the mean difference exceeds 5 K for the temperature and 20m/s for the zonal wind. The largest deviations are observed in winter when the variability from large-scale planetary waves dominates. Between lidar data and MPI-ESM-LR, there is an overall agreement in spectral amplitude down to 15-20 days. At shorter time scales, the variability is lacking in the model by similar to 10 dB. Infrasound observations indicate a general good agreement with ECWMF wind and temperature products. As such, this study demonstrates the potential of the infrastructure of the Atmospheric Dynamics Research Infrastructure in Europe project that integrates various measurements and provides a quantitative understanding of stratosphere-troposphere dynamical coupling for numerical weather prediction applications.

TI Surface and airborne measurements of organosulfur and methanesulfonate over the western United States and coastal areas SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article ID SECONDARY ORGANIC AEROSOL; ISOPRENE-DERIVED ORGANOSULFATES; 2011 E-PEACE; FLIGHT MASS-SPECTROMETRY; ATMOSPHERIC AEROSOLS; AMBIENT AEROSOLS; MARINE AEROSOL; CLOUD-WATER; LOS-ANGELES; AROMATIC ORGANOSULFATES AB This study reports on ambient measurements of organosulfur (OS) and methanesulfonate (MSA) over the western United States and coastal areas. Particulate OS levels are highest in summertime and generally increase as a function of sulfate (a precursor) and sodium (a marine tracer) with peak levels at coastal sites. The ratio of OS to total sulfur is also highest at coastal sites, with increasing values as a function of normalized difference vegetation index and the ratio of organic carbon to elemental carbon. Correlative analysis points to significant relationships between OS and biogenic emissions from marine and continental sources, factors that coincide with secondary production, and vanadium due to a suspected catalytic role. A major OS species, methanesulfonate (MSA), was examined with intensive field measurements, and the resulting data support the case for vanadium's catalytic influence. Mass size distributions reveal a dominant MSA peak between aerodynamic diameters of 0.32-0.56 mu m at a desert and coastal site with nearly all MSA mass (>= 84%) in submicrometer sizes; MSA: non-sea-salt sulfate ratios vary widely as a function of particle size and proximity to the ocean. Airborne data indicate that relative to the marine boundary layer, particulate MSA levels are enhanced in urban and agricultural areas and also the free troposphere when impacted by biomass burning. Some combination of fires and marine-derived emissions leads to higher MSA levels than either source alone. Finally, MSA differences in cloud water and out-of-cloud aerosol are discussed.

Approximately 65% of NSVIPR participants also inadvertently received Anthrax Vaccine Adsorbed (AVA) while pregnant, providing a ready opportunity to evaluate pregnancy and infant health outcomes among these women. AVA-exposed pregnancies were ascertained using NSVIPR and electronic healthcare data. Rates of pregnancy loss and infant health outcomes, including major birth defects, were compared between AVA-exposed and AVA-unexposed pregnancies. Analyses included AVA-exposed and AVA-unexposed pregnant women who also received smallpox vaccine 28 days prior to or during pregnancy. Rates of adverse outcomes among the AVA-exposed group were similar to or lower than expected when compared with published reference rates and the AVA-unexposed population. The findings provide reassurance of the safety of AVA when inadvertently received by a relatively young and healthy population during pregnancy. (C) 2015 Elsevier Ltd. All rights reserved.

Here we propose a rapid and facile strategy called the "layer hydrogen bonding pairing approach" to organize energetic molecules via layer-by-layer stacking, which grants access to tunable energetic materials with targeted properties. Using this strategy, an unusual energetic salt, hydroxylammonium 4-amino-furazan-3-yl-tetrazol-1-olate, with good detonation performances and excellent sensitivities, was designed, synthesized, and fully characterized. In addition, the expected unique layer-by-layer structure with a high crystal packing coefficient was confirmed by single-crystal X-ray crystallography. Calculations indicate that the layer-stacking structure of this material can absorb the mechanical stimuli-induced kinetic energy by converting it to layer sliding, which results in low sensitivity.

CA STAR Collaboration TI Precision Measurement of the Longitudinal Double-Spin Asymmetry for Inclusive Jet Production in Polarized Proton Collisions at root s=200 GeV SO PHYSICAL REVIEW LETTERS LA English DT Article ID PARTON DISTRIBUTIONS; UNCERTAINTIES AB We report a new measurement of the midrapidity inclusive jet longitudinal double-spin asymmetry, A(LL), in polarized pp collisions at center-of-mass energy root s = 200 GeV. The STAR data place stringent constraints on polarized parton distribution functions extracted at next-to-leading order from global analyses of inclusive deep-inelastic scattering (DIS), semi-inclusive DIS, and RHIC pp data. The measured asymmetries provide evidence at the 3 sigma level for positive gluon polarization in the Bjorken-x region x > 0.05.

TI Chromatic analysis and design of a first-order radial GRIN lens SO OPTICS EXPRESS LA English DT Article ID GRADIENT-INDEX LENSES; INHOMOGENEOUS LENSES; PARAXIAL ABERRATIONS; OPTICS; MEDIA AB From the expression for optical power of a radial first-order graded-index (GRIN) lens with curved surfaces, we derive an expression for chromatic aberration. Our expressions for optical power and chromatic aberration are valid under the paraxial approximation. By applying a series of further simplifying assumptions, namely a thin lens and thin GRIN, we derive a set of equations with which one can design an achromatic GRIN lens. We also derive expressions for the dispersive property of a GRIN element. Our analysis enables us to derive the relationship between material pairs that indicate their suitability as a material pair for a GRIN achromat. We use this relationship to search a standard glass catalog for attractive GRIN material pairs for a particular achromat design. We compare the optical performance of our GRIN design to that of a conventional homogeneous doublet and demonstrate that our approach is capable of identifying material pairs that perform well for achromatic GRIN lenses which would not generally be considered for conventional achromatic design. We also demonstrate our approach is capable of designing GRIN achromats with superior performance.

TI Degradation mechanisms of 2MeV proton irradiated AlGaN/GaN HEMTs SO APPLIED PHYSICS LETTERS LA English DT Article ID ELECTRON-MOBILITY TRANSISTORS; RADIATION; DEVICES AB Proton-induced damage in AlGaN/GaN HEMTs was investigated using energy-dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM), and simulated using a Monte Carlo technique. The results were correlated to electrical degradation using Hall measurements. It was determined by EDS that the interface between GaN and AlGaN in the irradiated HEMT was broadened by 2.2 nm, as estimated by the width of the Al EDS signal compared to the as-grown interface. The simulation results show a similar Al broadening effect. The extent of interfacial roughening was examined using high resolution TEM. At a 2 MeV proton fluence of 6 x 10(14) H+/cm(2), the electrical effects associated with the Al broadening and surface roughening include a degradation of the ON-resistance and a decrease in the electron mobility and 2DEG sheet carrier density by 28.9% and 12.1%, respectively.

CA STAR Collaboration TI Measurements of dielectron production in Au plus Au collisions at root s(NN)=200 GeV from the STAR experiment SO PHYSICAL REVIEW C LA English DT Article ID RELATIVISTIC NUCLEAR COLLISIONS; SUPER-PROTON SYNCHROTRON; HEAVY-ION COLLISIONS; DILEPTON PRODUCTION; CHIRAL RESTORATION; TRANSPORT APPROACH; SPS ENERGIES; CERN-SPS; MULTIPLICITY; FLOW AB We report on measurements of dielectron (e(+) e(-)) production in Au + Au collisions at a center-of-mass energy of 200 GeV per nucleon-nucleon pair using the STAR detector at BNL Relativistic Heavy Ion Collider. Systematic measurements of the dielectron yield as a function of transverse momentum (p(T)) and collision centrality show an enhancement compared to a cocktail simulation of hadronic sources in the low invariant-mass region (M-ee < 1 GeV / c(2)). This enhancement cannot be reproduced by the rho-meson vacuum spectral function. In minimum-bias collisions, in the invariant-mass range of 0.30-0.76 GeV / c(2), integrated over the full pT acceptance, the enhancement factor is 1.76 +/- 0.06 (stat.) +/- 0.26 (sys.) +/- 0.29 (cocktail). The enhancement factor exhibits weak centrality and pT dependence in STAR's accessible kinematic regions, while the excess yield in this invariant-mass region as a function of the number of participating nucleons follows a power-law shape with a power of 1.44 +/- 0.10. Models that assume an in-medium broadening of the rho-meson spectral function consistently describe the observed excess in these measurements. Additionally, we report on measurements of omega-and phi-meson production through their e+ e(-) decay channel. These measurements show good agreement with Tsallis blast-wave model predictions, as well as, in the case of the phi meson, results through its K+ K- decay channel. In the intermediate invariant-mass region (1.1 < Mee < 3 GeV / c(2)), we investigate the spectral shapes from different collision centralities. Physics implications for possible in-medium modification of charmed hadron production and other physics sources are discussed.

TI Far-ultraviolet morphology of star-forming filaments in cool core brightest cluster galaxies SO MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY LA English DT Article DE galaxies: active; galaxies: clusters: general; galaxies: clusters: intracluster medium; galaxies: star formation ID GALACTIC NUCLEUS FEEDBACK; RAY-LUMINOUS CLUSTERS; CENTRAL-DOMINANT-GALAXIES; X-RAY; FLOW CLUSTERS; MOLECULAR GAS; EMISSION-LINE; HYDRA-A; PERSEUS CLUSTER; ABELL 2597 AB We present a multiwavelength morphological analysis of star-forming clouds and filaments in the central (a parts per thousand(2)50 kpc) regions of 16 low-redshift (z < 0.3) cool core brightest cluster galaxies. New Hubble Space Telescope imaging of far-ultraviolet continuum emission from young (a parts per thousand(2)10 Myr), massive (a parts per thousand(3)5 M-aS (TM)) stars reveals filamentary and clumpy morphologies, which we quantify by means of structural indices. The FUV data are compared with X-ray, Ly alpha, narrow-band H alpha, broad-band optical/IR, and radio maps, providing a high spatial resolution atlas of star formation locales relative to the ambient hot (similar to 10(7-8) K) and warm ionized (similar to 10(4) K) gas phases, as well as the old stellar population and radio-bright active galactic nucleus (AGN) outflows. Nearly half of the sample possesses kpc-scale filaments that, in projection, extend towards and around radio lobes and/or X-ray cavities. These filaments may have been uplifted by the propagating jet or buoyant X-ray bubble, or may have formed in situ by cloud collapse at the interface of a radio lobe or rapid cooling in a cavity's compressed shell. The morphological diversity of nearly the entire FUV sample is reproduced by recent hydrodynamical simulations in which the AGN powers a self-regulating rain of thermally unstable star-forming clouds that precipitate from the hot atmosphere. In this model, precipitation triggers where the cooling-to-free-fall time ratio is t(cool)/t(ff) similar to 10. This condition is roughly met at the maximal projected FUV radius for more than half of our sample, and clustering about this ratio is stronger for sources with higher star formation rates.

The same function, with different constants d and k, also describes the relationship between Gamma(gamma) and peak Compton frequency nC. This behavior is derived analytically using an equipartition blazar model with a log-parabola description of the electron energy distribution (EED). In the Thomson regime, k=k(EC)=3b/4 for external Compton (EC) processes and k=k(SSC)=9b/16for synchrotron self-Compton (SSC) processes, where b is the log-parabola width parameter of the EED. The BL Lac object Mrk 501 is fit with a synchrotron/SSC model given by the log-parabola EED, and is best fit away from equipartition. Corrections are made to the spectral-index diagrams for a low-energy power-law EED and departures from equipartition, as constrained by absolute jet power. Analytic expressions are compared with numerical values derived from self-Compton and EC scattered gamma-ray spectra from Lya broad-line region and IR target photons. The Gamma(gamma) versus ns behavior in the model depends strongly on b, with progressively and predictably weaker dependences on gamma-ray detection range, variability time, and isotropic gamma-ray luminosity. Implications for blazar unification and blazars as ultra-high energy cosmic-ray sources are discussed. Arguments by Ghisellini et al. that the jet power exceeds the accretion luminosity depend on the doubtful assumption that we are viewing at the Doppler angle.

TI THE RECENT REJUVENATION OF THE SUN'S LARGE-SCALE MAGNETIC FIELD: A CLUE FOR UNDERSTANDING PAST AND FUTURE SUNSPOT CYCLES SO ASTROPHYSICAL JOURNAL LA English DT Article DE Sun: corona; Sun: coronal mass ejections (CMEs); Sun: magnetic fields; sunspots ID GALACTIC COSMIC-RAYS; CORONAL INFLOWS; SOLAR MINIMUM; CURRENT SHEET; MODULATION; INTERPLANETARY; DEPENDENCE; EVOLUTION; TRANSPORT; PHASE AB The quiet nature of sunspot cycle 24 was disrupted during the second half of 2014 when the Sun's large-scale field underwent a sudden rejuvenation: the solar mean field reached its highest value since 1991, the interplanetary field strength doubled, and galactic cosmic rays showed their strongest 27-day modulation since neutron-monitor observations began in 1957; in the outer corona, the large increase of field strength was reflected by unprecedentedly large numbers of coronal loops collapsing inward along the heliospheric current sheet. Here, we show that this rejuvenation was not caused by a significant increase in the level of solar activity as measured by the smoothed sunspot number and CME rate, but instead was caused by the systematic emergence of flux in active regions whose longitudinal distribution greatly increased the Sun's dipole moment. A similar post-maximum increase in the dipole moment occurred during each of the previous three sunspot cycles, and marked the start of the declining phase of each cycle. We note that the north-south component of this peak dipole moment provides an early indicator of the amplitude of the next cycle, and conclude that the amplitude of cycle 25 may be comparable to that of cycle 24, and well above the amplitudes obtained during the Maunder Minimum.

We compare these 90 GHz measurements, taken with the Multiplexed Squid/TES Array at Ninety Gigahertz (MUSTANG) receiver on the Green Bank Telescope, with generalized Navarro-Frenk-White (gNFW) models derived from Bolocam 140 GHz SZE data as well as maps of the thermal gas derived from Chandra X-ray observations. We adopt a serial-fitting approach, in which gNFW models are first fit to the Bolocam data and then compared to the MUSTANG data to determine an overall best-fit model. For MACS J0647.7+ 7015, we find a gNFW profile with core slope parameter gamma = 0.9 fits the MUSTANG image with chi(2)(red) = 1.005 and probability to exceed (PTE) = 0.34. For MACS J1206.2-0847, we find gamma = 0.7, chi(2)(red) = 0.993 and PTE = 0.70. In addition, we find a significant (> 3 sigma) residual SZE feature in MACS J1206.2-0847 coincident with a group of galaxies identified in Very Large Telescope data and filamentary structure found in a weak-lensing mass reconstruction. We suggest the detected sub-structure may be the SZE decrement from a low mass foreground group or an infalling group. Giant Metrewave Radio Telescope measurements at 610 MHz reveal diffuse extended radio emission to the west, which we posit is either an active galactic nucleus-driven radio lobe, a bubble expanding away from disturbed gas associated with the SZE signal, or a bubble detached and perhaps re-accelerated by sloshing within the cluster. Using the spectroscopic redshifts available,we find evidence for a foreground (z = 0.423) or infalling group, coincident with the residual SZE feature.

Several recent studies have proposed that the Sun's open flux consists of a constant or "floor" component that dominates at sunspot minimum, and a time-varying component due to coronal mass ejections (CMEs). Here, we point out that CMEs cannot account for the large peaks in the IMF strength which occurred in 2003 and late 2014, and which coincided with peaks in the Sun's equatorial dipole moment. We also show that near-Earth interplanetary CMEs, as identified in the catalog of Richardson and Cane, contribute at most similar to 30% of the average radial IMF strength even during sunspot maximum. We conclude that the long-term variation of the radial IMF strength is determined mainly by the Sun's total dipole moment, with the quadrupole moment and CMEs providing an additional boost near sunspot maximum. Most of the open flux is rooted in coronal holes, whose solar cycle evolution in turn reflects that of the Sun's lowest-order multipoles. C1 [Wang, Y. -M.; Sheeley, N.

TI Expanding the Operational Limits of the Single-Point Impedance Diagnostic for Internal Temperature Monitoring of Lithium-ion Batteries SO ELECTROCHIMICA ACTA LA English DT Article DE Electrochemical Impedance Spectroscopy; Lithium-Ion; Temperature Diagnostic ID LI-ION; ELECTROCHEMICAL IMPEDANCE; LITHIATED GRAPHITE; THERMAL-BEHAVIOR; SHORT-CIRCUIT; CELLS; SPECTROSCOPY; OVERCHARGE; MECHANISMS; ELECTRODES AB Instantaneous internal temperature monitoring of a commercial 18650 LiCoO2 lithium-ion battery was performed using a single-point EIS measurement. A correlation between the imaginary impedance, -Z(imag), and internal temperature at 300 Hz was developed that was independent of the battery's state of charge. An Arrhenius-type dependence was applied, and the activation energy for SEI ionic conductivity was found to be 0.13 eV. Two separate temperature-time experiments were conducted with different sequences of temperature, and single-point impedance tests at 300 Hz were performed to validate the correlation. Limitations were observed with the upper temperature range (68 degrees C < T< 95 degrees C), and consequently a secondary, empirical fit was applied for this upper range to improve accuracy. Average differences between actual and fit temperatures decreased around 3-7 degrees C for the upper range with the secondary correlation. The impedance response at this frequency corresponded to the anode/SEI layer, and the SEI is reported to be thermally stable up to around 100 degrees C, at which point decomposition may occur leading to battery deactivation and/or total failure. It is therefore of great importance to be able to track internal battery temperatures up to this critical point of 100 degrees C, and this work demonstrates an expansion of the single-point EIS diagnostic to these elevated temperatures.

We show how it is possible to change the lubrication regime from boundary lubrication to hydrodynamic lubrication even at relatively low shearing velocities by the addition of vertical pores to a compliant polymer. It is hypothesized that the compressed, pressurized liquid in the pores produces a repulsive hydrodynamic force as it extrudes from the pores. The presence of the fluid between two shearing surfaces results in low coefficients of friction (mu approximate to 0.31). The coefficient of friction is reduced further by using a boundary lubricant. The tribological properties are studied for a range of applied loads and shear velocities to demonstrate the potential applications of such materials in total joint replacement devices.

The molecular micelle is used as a chiral selector in capillary electrophoresis. This study is part of a larger effort to understand the mechanism of chiral recognition in capillary electrophoresis by characterizing the molecular micelle binding of chiral compounds with different geometries and charges. Propranolol and atenolol were chosen because their structures are similar, but their chiral interactions with the molecular micelle are different. Molecular dynamics simulations showed both propranolol enantiomers inserted their aromatic rings into the molecular micelle core and that (S)-propranolol associated more strongly with the molecular micelle than (R)-propranolol. This difference was attributed to stronger molecular micelle hydrogen bonding interactions experienced by (S)-propranolol. Atenolol enantiomers were found to bind near the molecular micelle surface and to have similar molecular micelle binding free energies. (C) 2015 The Authors. Published by Elsevier B.V.

TI Experimental Demonstration of Underwater Acoustic Scattering Cancellation SO SCIENTIFIC REPORTS LA English DT Article ID CLOAKING; TRANSPARENCY AB We explore an acoustic scattering cancellation shell for buoyant hollow cylinders submersed in a water background. A thin, low-shear, elastic coating is used to cancel the monopole scattering from an air-filled, neutrally buoyant steel shell for all frequencies where the wavelength is larger than the object diameter. By design, the uncoated shell also has an effective density close to the aqueous background, independently canceling its dipole scattering. Due to the significantly reduced monopole and dipole scattering, the compliant coating results in a hollow cylindrical inclusion that is simultaneously impedance and sound speed matched to the water background. We demonstrate the proposed cancellation method with a specific case, using an array of hollow steel cylinders coated with thin silicone rubber shells. These experimental results are matched to finite element modeling predictions, confirming the scattering reduction. Additional calculations explore the optimization of the silicone coating properties. Using this approach, it is found that scattering cross-sections can be reduced by 20 dB for all wavelengths up to k(0)alpha = 0.85.

Datta and Das predicted this precession would manifest as an oscillation in the source-drain conductance of the channel in a spin-injected field effect transistor (Spin FE I). The indium arsenide single quantum well materials system has proven to be ideal for experimental confirmation. The 2DES carriers have high mobility, low sheet resistance, and high spin orbit interaction. Techniques for electrical injection and detection of spin polarized carriers were developed over the last two decades. Adapting the proposed Spin FET to the Johnson Silsbee non-local geometry was a key to the first experimental demonstration of gate voltage controlled coherent spin precession. More recently, a new technique measured the oscillation as a function of channel length. This article gives an overview of the experimental phenomenology of the spin injection technique. We then review details of the application of the technique to InAs single quantum well (SQW) devices. The effective magnetic field associated with Rashba spin-orbit coupling is described, and a heuristic model of coherent spin precession is presented. The two successful empirical demonstrations of the Datta Das conductance oscillation are then described and discussed.

Residuals are analyzed between the data and empirical Global Average Mass Density Model (GAMDM) that takes into account density variability due to solar activity, season, geomagnetic activity, and long-term trend. A superposed epoch analysis of 37 SSW events reveals a density reduction of 3-7% at 250-575km around the time of maximum polar vortex weakening. The relative density perturbation is found to be greater at higher altitudes. The temperature perturbation is estimated to be -7.0K at 400km. We show that the density reduction can arise from enhanced wave forcing from the lower atmosphere. C1 [Yamazaki, Yosuke; Kosch, Michael J.] Univ Lancaster, Dept Phys, Lancaster, England.

The overlap of the cross-sections in the transitions H-3(6) -> H-3(5) and H-3(5) -> H-3(4) enable both transitions to simultaneously amplify a single wavelength in the range between 4.25 mu m and 4.55 mu m. High gain and low noise are achieved simultaneously if the signal is at 4.5 mu m. We show that 45% of pump power that is injected at 2 mu m can be shifted to 4.5 mu m. The efficiency of using a mid-IR fiber amplifier is higher than what can be achieved by using mid-IR supercontinuum generation, which has been estimated at 25%. This mid-IR fiber amplifier can be used in conjunction with quantum cascade lasers to obtain a tunable, high-power mid-IR source.

TI A high degree of enhancement of strength of sputter deposited Al/Al2O3 multilayers upon post annealing SO ACTA MATERIALIA LA English DT Article DE Metal/ceramic multilayers; Advanced nanocomposites; Strengthening mechanisms; Modified Hall-Petch; DFT simulations ID AUGMENTED-WAVE METHOD; MECHANICAL-PROPERTIES; ALUMINUM; COMPOSITES; BEHAVIOR; ALLOYS; DEFORMATION; GRADIENT; COATINGS; SURFACE AB We report here an order of magnitude enhancement of strength of sputter deposited Al/Al2O3 multilayers after annealing. The increase in strength is shown to be mostly associated with the precipitation of extremely fine gamma-Al2O3, 5-10 nm in diameter, in Al layers. This provides a new method of achieving high strength in Al/Al2O3 multilayers that cannot be explained by the Koehler effect or modified Hall-Petch, which will lead to the growth and development of new generation of Al/Al2O3 multilayers. We also examine the fracture behavior of the post annealed Al/Al2O3 multilayered composites with TEM and density functional theory (DFT) simulations. DFT showed that the multilayers are not likely to delaminate at the Al/Al2O3 interface, consistent with the experimental observations. The simulations are also used to determine elastic constants for the gamma-Al2O3 phase and to calculate a driving force for O transport from the gamma-Al2O3 to the Al layers. The formation of these precipitates is consistent with DFT calculations, which predict an energetic driving force for the dissolution of O atoms from the gamma-Al2O3 layers into the Al layers.

The molecules consist of several coupled quantum dots, each of which comprises a chain of charged adatoms that electrostatically confines intrinsic surface-state electrons. The coupling takes place across tunnel barriers created reversibly using the STM tip.

Here, the structure of stable silver carbon alloys is described, which are produced by thermoelectrically charging molten silver with carbon ions. Transmission electron microscopy and Raman scattering are combined to establish that large amount of carbon is accommodated in the form of epitaxial graphene-like sheets. The carbon bonds covalently to the silver matrix as predicted from density functional theory (DFT) calculations with bond energies in the range 1.1-2.2 eV per atom or vacancy. Graphitic-like sheets embedded in the crystal lattice of silver form 3D epitaxial structures with the host metal with a strain of approximate to 13% compared to equilibrium graphene. The carbon nanostructures persist upon remelting and resolidification. A DFT-based analysis of the phonon density of states confirms the presence of intense vibration modes related to the AgC bonds observed in the Raman spectra of the alloy. The solid silver-high carbon alloy, termed Ag-covetic, displays room temperature electrical conductivity of 5.62 x 10(7) S m(-1) even for carbon concentrations of up to approximate to 6 wt% (36 at%). This process of incorporation of carbon presents a new paradigm for electrocharging assisted bulk processing.

In previous work, we created a new theoretical formalism for describing the PSDs and time lags produced via a combination of stochastic particle injection and emission via the synchrotron, synchrotron self-Compton, and external Compton (EC) processes. This formalism used the Thomson cross section and simple delta-function approximations to model the synchrotron and Compton emissivities. Here we expand upon this work, using the full Compton cross section and detailed and accurate emissivities. Our results indicate good agreement between the PSDs computed using the delta-function approximations and those computed using the accurate expressions, provided the observed photons are produced primarily by electrons with energies exceeding the lower limit of the injected particle population. Breaks are found in the PSDs at frequencies corresponding to the cooling timescales of the electrons primarily responsible for the observed emission, and the associated time lags are related to the difference in electron cooling timescales between the two energy channels, as expected. If the electron cooling timescales can be determined from the observed time lags and/or the observed EC PSDs, then one could in principle use the method developed here to determine the energy of the external seed photon source for EC, which is an important unsolved problem in blazar physics.

TI Simulation of a partially depleted absorber (PDA) photodetector SO OPTICS EXPRESS LA English DT Article ID IMPACT-IONIZATION; AVALANCHE PHOTODIODES; OPTICAL-ABSORPTION; NOISE; FIELD; NONLINEARITY; CHARGE; MODEL; GAIN AB We use a 2D drift-diffusion model to study the nonlinear response of a partially depleted absorber (PDA) phododetector. The model includes external loading, incomplete ionization, the Franz-Keldysh effect, and history-dependent impact ionization. It also takes into account heat flow in the device. With all these effects included, we obtain excellent agreement with experiments for the responsivity and for the harmonic power at different modulation frequencies. The role of these different physical effects is elucidated, and we find that both the Franz-Keldysh effect and the load resistance play a key role in generating higher harmonic power at larger reverse biases. Increasing the size of the p-region absorption layers reduces the impact of the Franz-Keldysh effect. Decreasing the effective load resistance also decreases the higher harmonic powers. We also show that the model can suggest design changes that will improve device performance.

TI PSR J1906+0722: AN ELUSIVE GAMMA-RAY PULSAR SO ASTROPHYSICAL JOURNAL LETTERS LA English DT Article DE gamma rays: stars; pulsars: individual (PSR J1906+0722) ID LARGE-AREA TELESCOPE; FERMI UNASSOCIATED SOURCES; REMNANT 3C 397; SOURCE CATALOG; SEARCHES; MULTIWAVELENGTH; DISCOVERY; MODEL; YOUNG AB We report the discovery of PSR J1906+0722, a gamma-ray pulsar detected as part of a blind survey of unidentified Fermi Large Area Telescope (LAT) sources being carried out on the volunteer distributed computing system, Einstein@Home. This newly discovered pulsar previously appeared as the most significant remaining unidentified gamma-ray source without a known association in the second Fermi-LAT source catalog (2FGL) and was among the top 10 most significant unassociated sources in the recent third catalog (3FGL). PSR J1906+0722 is a young, energetic, isolated pulsar, with a spin frequency of 8.9 Hz, a characteristic age of 49 kyr, and spin-down power 1.0 x 10(36) erg s(-1). In 2009 August it suffered one of the largest glitches detected from a gamma-ray pulsar (Delta f/f approximate to 4.5 x 10(-6)). Remaining undetected in dedicated radio follow-up observations, the pulsar is likely radio-quiet. An off-pulse analysis of the gamma-ray flux from the location of PSR J1906+0722 revealed the presence of an additional nearby source, which may be emission from the interaction between a neighboring supernova remnant and a molecular cloud. We discuss possible effects which may have hindered the detection of PSR J1906+0722 in previous searches and describe the methods by which these effects were mitigated in this survey. We also demonstrate the use of advanced timing methods for estimating the positional, spin and glitch parameters of difficult-to-time pulsars such as this. C1 [Clark, C. J.; Pletsch, H.

Corey Fuchs olefination followed by reaction with n-BuLi led to various 1-(2-ethynylphenyl)naphthalenes. Cycloisomerization of individual 1-(2-ethynylphenyl)naphthalenes to various benzo[c]phenanthrene (BcPh) analogues was accomplished smoothly with catalytic PtCl2 in PhMe. In the case of 4,5-dihydrobenzo[l]acephenanthrylene, oxidation with DDQ gave benzo[l]acephenanthrylene. The dimethoxy-substituted benzo[c]phenanthrenes were demethylated with BBr3 and oxidized to the o-quinones with PDC. Reduction of these quinones with NaBH4 in THF/EtOH in an oxygen atmosphere gave the respective dihydrodiols. Exposure of the dihydrodiols to N-bromoacetamide in THF-H2O led to bromohydrins that were cydized with Amberlite IRA 400 HO- to yield the series 1 diol epoxides. Epoxidation of the dihydrodiols with mCPBA gave the isomeric series 2 diol epoxides. All of the hydrocarbons as well as the methoxy-substituted ones were crystallized and analyzed by X-ray crystallography, and these data are compared to other previously studied BcPh derivatives. The methodology described is highly modular and can be utilized for the synthesis of a wide variety of angularly fused polycyclic aromatic hydrocarbons and their putative metabolites and/or other derivatives.

CA STAR Collaboration TI Energy dependence of K pi, p pi, and Kp fluctuations in Au plus Au collisions from root s(NN)=7.7 to 200 GeV SO PHYSICAL REVIEW C LA English DT Article ID DECONFINEMENT PHASE-TRANSITION; NUCLEUS-NUCLEUS COLLISIONS; BY-EVENT FLUCTUATIONS; STAR EXPERIMENT AB A search for the quantum chromodynamics (QCD) critical point was performed by the STAR experiment at the BNL Relativistic Heavy Ion Collider, using dynamical fluctuations of unlike particle pairs. Heavy ion collisions were studied over a large range of collision energies with homogeneous acceptance and excellent particle identification, covering a significant range in the QCD phase diagram where a critical point may be located. Dynamical K pi, p pi, and Kp fluctuations as measured by the STAR experiment in central 0-5% Au + Au collisions from center-of-mass collision energies root s(NN) = 7.7 to 200 GeV are presented. The observable nu(dyn) was used to quantify the magnitude of the dynamical fluctuations in event-by-event measurements of the Kp, pp, and Kp pairs. The energy dependences of these fluctuations from central 0-5% Au + Au collisions all demonstrate a smooth evolution with collision energy.

TI Improvements in dizziness and imbalance results from using a multi disciplinary and multi sensory approach to Vestibular Physical Therapy - a case study SO FRONTIERS IN SYSTEMS NEUROSCIENCE LA English DT Article DE CAREN; vestibular physical therapy; virtual reality; treadmill; traumatic brain injury; TBI ID TRAUMATIC BRAIN-INJURY; DYSFUNCTION; POSTURE AB This paper discusses a case study of a 41-year-old active duty male service member who sustained head trauma from a motorcycle accident and underwent multidisciplinary vestibular physical therapy rehabilitation. He was initially treated with traditional physical therapy applications of treadmill walking and standing balance with some symptom improvements, but was not able to maintain a running speed that would allow him to return to full active duty status. Further treatment utilizing a Computer Assisted Rehabilitation Environment was performed in order to increase level of difficulty and further enhance function. This treatment is able to elicit vestibular deficits seen in the community as it requires subjects to walk and balance while performing tasks within a virtual scenario incorporating platform motion, visual surround and flow, and cognitive processing. After 6 weeks of therapy, twice weekly, improvements in clinical vestibular measures were observed as well as walking speed and patient confidence. The patient was able to return to full duty after treatment. This case study provides supportive evidence that multidimensional tasking in a virtual environment provides a safe but demanding form of vestibular therapy for patients needing more challenging tasks than those provided with traditional therapy techniques. Those persons requiring higher levels of performance before returning to full duty (e.g., pilots, special operators, etc.) may find this type of therapy beneficial.

TI Correlating Changes in Electron Lifetime and Mobility on Photocatalytic Activity at Network-Modified TiO2 Aerogels SO JOURNAL OF PHYSICAL CHEMISTRY C LA English DT Article ID MODULATED PHOTOCURRENT SPECTROSCOPY; NANOCRYSTALLINE PHOTOVOLTAIC CELLS; SOLAR-CELLS; TERAHERTZ SPECTROSCOPY; GOLD NANOPARTICLES; SIZE QUANTIZATION; TITANIUM-DIOXIDE; CARRIER DYNAMICS; BACK-REACTION; FILMS AB We use intensity-modulated photovoltage spectroscopy (IMVS) and intensity-modulated photocurrent spectroscopy (IMPS) to characterize Carrier dynamics in titania (TiO2) aerogels under photocatalytic conditions. By systematically increasing the weight fraction of the sol gel precursor during TiO2 sol-gel synthesis, we are able to impart drastic changes in Carrier transport/trapping and improve the photocatalytic activity of TiO2 aerogels for two mechanistically divergent photochemical reactions: reductive water splitting (H-2 generation) and oxidative degradation of dichloroacetate (DCA). The lifetimes of photogenerated electrons increase in going from lowest-to-highest precursor concentrations, as measured by IMVS, indicating increasing site density for electron traps a trend that correlates with an 8X improvement for photo catalytic H-2 generation. Electron mobility in the aerogel films, as measured by IMPS, decreases with increasing trap density, further implicating the trapping sites as reactive sites. In contrast, photocatalytic DCA degradation driven primarily by direct hole transfer to adsorbed DCA-depends only weakly on the electron dynamics in the film. Transient infrared spectroscopy shows no difference in carrier decay among the aerogel samples on picosecond time scales, indicating that changes in carrier dynamics within these networked nanomaterials are only observable at time scales measured by IMPV and IMPS. Correlating hole-mediated and electron-mediated photo catalytic activity with direct measurement of election dynamics under photocatalytically relevant conditions and time scales comprises a powerful approach to determine how synthetic modifications to networked nanostructured photocatalysts affect the relevant physicochemical phenomena underlying their photocatalytic performance.

TI A surface-enhanced Raman study of N-methylquinolinium tricyanoquinodimethanide adsorbed on Ag nanospheres: Determination of molecular orientation and order SO SPECTROCHIMICA ACTA PART A-MOLECULAR AND BIOMOLECULAR SPECTROSCOPY LA English DT Article DE Surface enhanced Raman; DFT ID SCANNING-TUNNELING-MICROSCOPY; SELF-ASSEMBLED MONOLAYERS; HEXADECYLQUINOLINIUM TRICYANOQUINODIMETHANIDE; ELECTRICAL RECTIFICATION; ELECTRONIC DEVICES; GOLD ELECTRODES; RECTIFIERS; OLIGO(PHENYLENE-ETHYNYLENE)S; CONDUCTANCE AB Quinolinium tricyanoquinodimethanides are among the most promising molecules for electronic applications. Disorder can be detrimental to the desired electronic properties of a monolayer, and as such, a reliable method to characterize a monolayer without destroying or creating defects is paramount to determining potential applications. Here, the normal and surface-enhanced Raman scattering spectra of N-methylquinolinium tricyanoquinodimethanide (CH(3)Q-3CNQ) on silver coated nanosurfaces have been obtained and analyzed. Theoretical treatment of CH(3)Q-3CNQ was performed. Optimization and frequency search was conducted using the B3LYP functional with the 6-31G(d) basis set. A complete list of frequencies and assignments for the molecules are presented. The spectroscopic evidence points to the fact that a monolayer of CH(3)Q-3CNQ can be formed through the self-assembly process, and the SERS data indicate that the monolayer attaches to the silver surface through the nitrile groups.

This high frequency image acquisition makes it possible to study more detailed dynamics of red tide blooms, sediment plumes, and colored dissolved organic matter plumes, and can aid in the prediction of biophysical phenomena. We apply the red band difference and the fluorescence line height algorithms to GOCI imagery to separate waters with high algal and nonalgal particles and validate the results with the MODIS imagery. We also track optical features using hourly GOCI imagery and assess their movement through comparisons with predicted ocean currents derived from the navy coastal ocean model and tidal data.

TI Threshold displacement energies in graphene and single-walled carbon nanotubes SO PHYSICAL REVIEW B LA English DT Article ID MOLECULAR-DYNAMICS; ELECTRON; STABILITY AB The threshold displacement energy E-d has been determined for graphene and 216 different (n, m) single-walled carbon nanotube chiralities, with 5 <= n <= 20 and 0 <= m <= n, under several model conditions using classical molecular dynamics. The model conditions vary by particle (electron or carbon ion), empirical potential (two parametrizations of Tersoff [J. Tersoff, Phys. Rev. B 39, 5566 (1989); L. Lindsay and D. A. Broido, 81, 205441 (2010)] and one of Brenner et al. [D. W. Brenner, O. A. Shenderova, J. A. Harrison, S. J. Stuart, B. Ni, and S. B. Sinnott, J. Phys.: Condens. Matter 14, 783 (2002)]), and momentum transfer direction (towards or away from the nanotube axis). For electron irradiation simulations, E-d exhibits a smoothly varying chirality dependence and a characteristic curvature influenced by the momentum transfer direction. Changing the empirical potential shifts the magnitude of E-d, but the trend is preserved for electron simulations. However, the perturbation in the knock-on dynamics introduced by the carbon ion leads to E-d trends that diverge from the equivalent electron simulation. Thus, the ion interaction has a non-negligible effect on the dynamics of the collision and leads to E-d values that can distinctly vary depending on the selected carbon nanostructure.

We present detections of periodic emission from 44 previously known pulsars, including 3 millisecond pulsars. The effects of the interstellar medium (ISM) on pulsar emission are significantly enhanced at the low frequencies of the LWA1 band (10-88 MHz), making LWA1 a very sensitive instrument for characterizing changes in the dispersion measure (DM) and other effects from the ISM. Pulsars also often have significant evolution in their pulse profile at low frequency and a break in their spectral index. We report DM measurements for 44 pulsars, mean flux density measurements for 36 pulsars, and multi-frequency component spacing and widths for 15 pulsars with more than one profile component. For 27 pulsars, we report spectral index measurements within our frequency range. We also introduce the LWA1 Pulsar Data Archive, which stores reduced data products from LWA1 pulsar observations. Reduced data products for the observations presented here can be found in the archive. Reduced data products from future LWA1 pulsar observations will also be made available through the archive.

In this study, an in silico subtractive proteomic strategy was used to identify a novel 101 kDa GH3 family beta-glucosidase (LamN) that was found in bioluminescent Vibrio campbellii strains capable of utilizing the algal storage glucan laminarin. A heterologous overexpression system verified the sequence-predicted function of LamN as it enabled the growth of Escherichia coli on laminarin as a sole carbon source. Quantitative reverse transcription PCR analyses revealed that V. campbellii grown on laminarin demonstrated a 4- to 314-fold induction of lamN gene expression when compared to the same strains grown on glucose or glycerol. Corresponding tandem mass spectrometric analyses detected LamN protein expression only in cells grown on laminarin. Heterologous expression, purification and biochemical characterization identified LamN as a heat stable laminarinase with beta-1,3, beta-1,4 and beta-1,6 glucosidase activity. Collectively, these data identify an enzyme that may allow V. campbellii to exploit some of the most abundant polysaccharides associated with deteriorating phytoplankton blooms and provide support for the potential involvement of V. campbellii in the formation of bioluminescent milky seas.

During a time that has witnessed the rapid emergence of a variety of national space programs even among lesser powers like Iran and South Korea Brazil's failure to emerge as a significant space actor requires further analysis. This article traces the history of Brazil's space efforts and examines the factors that have held it back, some of which continue to influence its policies today: inadequate funding, conflicting organizations, poorly handled foreign relations, and an unclear national vision for Brazil's "place" in space. Recent efforts to overcome these hurdles through an improved domestic strategy and smarter international relations show promise. But a more sustained political commitment to space development will be needed if they are to succeed. Published by Elsevier Ltd.

Measurements of fluid velocity were made using Particle Image Velocimetry. The strength of the fluid shear stresses and the pressure gradients were examined for a range of oscillatory flow conditions at the onset of motion of the sediment particles to determine which mechanism had induced particle motion. The three sediment types utilized in these experiments facilitated an assessment of the effects of sediment grain size diameter, shape, and density on incipient motion. Results suggested that the onset of sediment motion was dominated by the pressure gradients for flows with small orbital excursion amplitudes, by the shear stresses for flows with large orbital excursion amplitudes and by the combined effects for intermediate flows. The denser, angular gravel required greater free-stream accelerations to trigger sediment motion than the spherical, less dense acetate beads, and Smart Sediment Grains. A combined parameter for incipient motion that accounts for the simultaneous effects of both shear stresses and pressure gradients while depending on the static coefficient of friction and the packing concentration of the mobile bed layer was evaluated for accuracy using a range of sediment types. The results suggested that the combined parameter may be a better indicator of sediment mobilization under oscillatory flows than the typically assumed shear stress criterion.

Joseph TI Bathymetrically controlled velocity-shear front at a tidal river confluence SO JOURNAL OF GEOPHYSICAL RESEARCH-OCEANS LA English DT Article ID CHANNEL CONFLUENCES; SHALLOW ESTUARIES; CIRCULATION; TOPOGRAPHY; RADAR; WATER; FLOW; BAY AB Nonbuoyant front formation at the confluence of Nanjemoy Creek and the main Potomac River (MD) channel is examined. Terra satellite ASTER imagery reveals a sediment color front emerging from Nanjemoy Creek when the Potomac is near maximum ebb. Nearly contemporaneous ASTER and Landsat ETM1 imagery are used to extract surface velocities, which suggest a velocity shear front is collocated with the color front. In situ velocities (measured by RiverRay traverses near the Nanjemoy Creek mouth) confirm the shear front's presence. A finite-element simulation (using ADCIRC) replicates the observed velocity-shear front and is applied to decipher its physics. Three results emerge: (1) the velocity-shear front forms, confined to a shoal downstream of the creek-river confluence for most of the tidal cycle, (2) a simulation with a flat bottom in Nanjemoy Creek and Potomac River (i.e., no bathymetry variation) indicates the velocity-shear front never forms, hence the front cannot exist without the bathymetry, and (3) an additional simulation with a blocked-off Creek entrance demonstrates that while the magnitude of the velocity shear is largely unchanged without the creek, shear front formation is delayed in time. Without the Creek, there is no advection of the M-6 tidal constituent (generated by nonlinear interaction of the flow with bottom friction) onto the shoals, only a locally generated contribution. A tidal phase difference between Nanjemoy and Potomac causes the ebbing Nanjemoy Creek waters to intrude into the Potomac as far south as its deep channel, and draw from a similar location in the Potomac during Nanjemoy flood.

TI UV solar irradiance in observations and the NRLSSI and SATIRE-S models SO JOURNAL OF GEOPHYSICAL RESEARCH-SPACE PHYSICS LA English DT Article DE solar irradiance; solar variability ID II SOLSTICE-II; SPECTRAL IRRADIANCE; SEMIEMPIRICAL MODELS; BACKSCATTERED ULTRAVIOLET; STRATOSPHERIC OZONE; CYCLE VARIATION; VARIABILITY; RECONSTRUCTION; ATMOSPHERE; CLIMATE AB Total solar irradiance and UV spectral solar irradiance has been monitored since 1978 through a succession of space missions. This is accompanied by the development of models aimed at replicating solar irradiance by relating the variability to solar magnetic activity. The Naval Research Laboratory Solar Spectral Irradiance (NRLSSI) and Spectral And Total Irradiance REconstruction for the Satellite era (SATIRE-S) models provide the most comprehensive reconstructions of total and spectral solar irradiance over the period of satellite observation currently available. There is persistent controversy between the various measurements and models in terms of the wavelength dependence of the variation over the solar cycle, with repercussions on our understanding of the influence of UV solar irradiance variability on the stratosphere. We review the measurement and modeling of UV solar irradiance variability over the period of satellite observation. The SATIRE-S reconstruction is consistent with spectral solar irradiance observations where they are reliable. It is also supported by an independent, empirical reconstruction of UV spectral solar irradiance based on Upper Atmosphere Research Satellite/Solar Ultraviolet Spectral Irradiance Monitor measurements from an earlier study. The weaker solar cycle variability produced by NRLSSI between 300 and 400nm is not evident in any available record. We show that although the method employed to construct NRLSSI is principally sound, reconstructed solar cycle variability is detrimentally affected by the uncertainty in the SSI observations it draws upon in the derivation. Based on our findings, we recommend, when choosing between the two models, the use of SATIRE-S for climate studies. C1 [Yeo, K. L.; Krivova, N. A.; Solanki, S.

The diagnostics include GPS scintillations, ground-based stimulated electromagnetic emission (SEE), the HAARP ionosonde, Kodiak radar, and signals received at the Ukrainian Antarctic Station (UAS). The latter allowed analysis of waves scattered by the AIT into the ionospheric waveguide along Earth's terminator, 15.6mm from the HAARP facility. For the first time, the amplitudes of two prominent SEE features, the downshifted maximum and broad upshifted maximum, were observed to saturate at similar to 50% of the maximum HAARP effective radiated power. Nonlinear effects in slant total electron content, SEE, and signals received at UAS at different transmitted frequencies and intensities of the pump wave were observed. The correlations between the data from different detectors demonstrate that the scattered waves reach UAS by the waveguide along the Earth's terminator, and that they were injected into the waveguide by scattering off of artificial striations produced by AIT above HAARP, rather than via direct injection from sidelobe radiation.

TI Wind Magnetic Clouds for 2010-aEuro parts per thousand 2012: Model Parameter Fittings, Associated Shock Waves, and Comparisons to Earlier Periods SO SOLAR PHYSICS LA English DT Article DE Magnetic cloud; Interplanetary shock; Magnetic cloud-like structure; Model ID CORONAL MASS EJECTIONS; 23RD SOLAR MINIMUM; 1 AU; EMPIRICAL RECONSTRUCTION; INTERACTION REGION; INNER HELIOSPHERE; COMPLEX EJECTA; FLUX ROPES; INTERPLANETARY; EARTH AB We fitted the parameters of magnetic clouds (MCs) as identified in the Wind spacecraft data from early 2010 to the end of 2012 using the model of Lepping, Jones, and Burlaga (J. Geophys. Res. 95, 1195, 1990). The interval contains 48 MCs and 39 magnetic cloud-like (MCL) events. This work is a continuation of MC model fittings of the earlier Wind sets, including those in a recent publication, which covers 2007 to 2009. This period (2010 -aEuro parts per thousand 2012) mainly covers the maximum portion of Solar Cycle 24. Between the previous and current interval, we document 5.7 years of MCs observations. For this interval, the occurrence frequency of MCs markedly increased in the last third of the time. In addition, over approximately the last six years, the MC type (i.e. the profile of the magnetic-field direction within an MC, such as North-to-South, South-to-North, all South) dramatically evolved to mainly North-to-South types when compared to earlier years. Furthermore, this evolution of MC type is consistent with global solar magnetic-field changes predicted by Bothmer and Rust (Coronal Mass Ejections, 139, 1997). Model fit parameters for the MCs are listed for 2010 -aEuro parts per thousand 2012. For the 5.7 year interval, the observed MCs are found to be slower, weaker in estimated axial magnetic-field intensity, and shorter in duration than those of the earlier 12.3 years, yielding much lower axial magnetic-field fluxes. For about the first half of this 5.7 year period, i.e. up to the end of 2009, there were very few associated MC-driven shock waves (distinctly fewer than the long-term average of about 50 % of MCs). But since 2010, such driven shocks have increased markedly, reflecting similar statistics as the long-term averages. We estimate that 56 % of the total observed MCs have upstream shocks when the full interval of 1995 -aEuro parts per thousand 2012 is considered. However, only 28 % of the total number of MCLs have driven shocks over the same period. Some interplanetary shocks during the 2010 -aEuro parts per thousand 2012 interval are seen to apparently occur without an obvious MC-driver, probably indicating an encounter with a distant flank of a MC-driven shock. Some of these may be driven by a different kind of structure, however. C1 [Lepping, R. P.; Szabo, A.] NASA, Goddard Space Flight Ctr, Heliophys Sci Div, Greenbelt, MD 20771 USA.

TI Ambulance Diversion Associated With Reduced Access To Cardiac Technology And Increased One-Year Mortality SO HEALTH AFFAIRS LA English DT Article ID ACUTE MYOCARDIAL-INFARCTION; TIME; DISEASE; ARREST; IMPACT AB Ambulance diversion, which occurs when a hospital emergency department (ED) is temporarily closed to incoming ambulance traffic, is an important system-level interruption that causes delays in treatment and potentially lower quality of care. There is little empirical evidence investigating the mechanisms through which ambulance diversion might affect patient outcomes. We investigated whether ambulance diversion affects access to technology, likelihood of treatment, and ultimately health outcomes for Medicare patients with acute myocardial infarction in twenty-six California counties. We found that patients whose nearest hospital ED had significant ambulance diversions experienced reduced access to hospitals with cardiac technology. This led to a 4.6 percent decreased likelihood of revascularization and a 9.8 percent increase in one-year mortality compared to patients who did not experience diversion. Policy makers may wish to consider creating a policy to specifically manage certain time-sensitive conditions that require technological intervention during periods of ambulance diversion.

The field experiment gathered detailed information on the chemical composition of the inflow and outflow regions of midlatitude thunderstorms in northeast Colorado, west Texas to central Oklahoma, and northern Alabama. A unique aspect of the DC3 strategy was to locate and sample the convective outflow a day after active convection in order to measure the chemical transformations within the upper-tropospheric convective plume. These data are being analyzed to investigate transport and dynamics of the storms, scavenging of soluble trace gases and aerosols, production of nitrogen oxides by lightning, relationships between lightning flash rates and storm parameters, chemistry in the upper troposphere that is affected by the convection, and related source characterization of the three sampling regions. DC3 also documented biomass-burning plumes and the interactions of these plumes with deep convection.

TI The LatMix Summer Campaign: Submesoscale Stirring in the Upper Ocean SO BULLETIN OF THE AMERICAN METEOROLOGICAL SOCIETY LA English DT Article ID INTERNAL WAVES; MIXED-LAYER; VERTICAL MOTION; PART I; DISPERSION; INSTABILITIES; SIMULATIONS; DISSIPATION; PYCNOCLINE; TURBULENCE AB Lateral stirring is a basic oceanographic phenomenon affecting the distribution of physical, chemical, and biological fields. Eddy stirring at scales on the order of 100 km (the mesoscale) is fairly well understood and explicitly represented in modern eddy-resolving numerical models of global ocean circulation. The same cannot be said for smaller-scale stirring processes. Here, the authors describe a major oceanographic field experiment aimed at observing and understanding the processes responsible for stirring at scales of 0.1-10 km. Stirring processes of varying intensity were studied in the Sargasso Sea eddy field approximately 250 km southeast of Cape Hatteras. Lateral variability of water-mass properties, the distribution of microscale turbulence, and the evolution of several patches of inert dye were studied with an array of shipboard, autonomous, and airborne instruments. Observations were made at two sites, characterized by weak and moderate background mesoscale straining, to contrast different regimes of lateral stirring. Analyses to date suggest that, in both cases, the lateral dispersion of natural and deliberately released tracers was O(1) m(2) s(-1) as found elsewhere, which is faster than might be expected from traditional shear dispersion by persistent mesoscale flow and linear internal waves. These findings point to the possible importance of kilometer-scale stirring by submesoscale eddies and nonlinear internal-wave processes or the need to modify the traditional shear-dispersion paradigm to include higher-order effects. A unique aspect of the Scalable Lateral Mixing and Coherent Turbulence (LatMix) field experiment is the combination of direct measurements of dye dispersion with the concurrent multiscale hydrographic and turbulence observations, enabling evaluation of the underlying mechanisms responsible for the observed dispersion at a new level.

In most cases these materials must be conjugated to different types of biologicals such as proteins or DNA to accomplish this. However, most traditional methods of bioconjugation result in heterogeneous attachment and loss of activity. Bioorthogonal chemistries and in particular enzymatic labeling chemistries offer new strategies for catalyzing specific biomolecular attachment. We highlight current enzymatic labeling methods available for bioconjugating nanoparticles, some materials they have been used with, and how the resulting bioconjugates were applied. A discussion of the benefits and remaining issues associated with this type of bioconjugation chemistry and a brief perspective on how this field will develop is also provided.

TI Increasing the activity of immobilized enzymes with nanoparticle conjugation SO CURRENT OPINION IN BIOTECHNOLOGY LA English DT Review ID GRAPHENE OXIDE; QUANTUM DOTS; GOLD NANOPARTICLES; ENHANCED ACTIVITY; PERFORMANCE; SIZE; FABRICATION; BIOSENSORS; SURFACES; SYSTEM AB The efficiency and selectivity of enzymatic catalysis is useful to a plethora of industrial and manufacturing processes. Many of these processes require the immobilization of enzymes onto surfaces, which has traditionally reduced enzyme activity. However, recent research has shown that the integration of nanoparticles into enzyme carrier schemes has maintained or even enhanced immobilized enzyme performance. The nanoparticle size and surface chemistry as well as the orientation and density of immobilized enzymes all contribute to the enhanced performance of enzyme-nanoparticle conjugates. These improvements are noted in specific nanoparticles including those comprising carbon (e.g., graphene and carbon nanotubes), metal/metal oxides and polymeric nanomaterials, as well as semiconductor nanocrystals or quantum dots.

An underlying SU (3) group structure at each spatial point regulates the theory. The intrinsic time behavior of the theory is analyzed, together with its ground state and primordial quantum fluctuations. Cotton-York potential dominates at early times when the universe was small; the ground state naturally resolves Penrose's Weyl curvature hypothesis, and thermodynamic and gravitational "arrows of time" point in the same direction. Ricci scalar potential corresponding to Einstein's general relativity emerges as a zero-point energy contribution. A new set of fundamental commutation relations without Planck's constant emerges from the unification of gravitation and quantum mechanics.

Corridors were 80-100 cm wide and 2-4m long. Using the two-choice Y-shaped paradigm to compensate for left-right bias and spatial memory, a moveable, weakly reflective thin-net barrier randomly blocked the left or right corridor, interspersed with no-barrier trials. Flight path and beam aim were tracked using an array of 24 microphones surrounding the flight room. Each bat flew on a path centered in the entry corridor (base of Y) and then turned into the left or right passage, to land on the far wall or to turn abruptly, reacting to avoid a collision. Broadcasts were broadly beamed in the direction of flight, smoothly leading into an upcoming turn. Duration of broadcasts decreased slowly from 3 to 2 ms during flights to track the chains' progressively closer ranges. Broadcast features and flight velocity changed abruptly about 1m from the barrier, indicating that echoes from the net were perceived even though they were 18-35 dB weaker than overlapping echoes from surrounding chains.

TI A highly directional transducer for multipath mitigation in high-frequency underwater acoustic communications SO JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA LA English DT Article AB This paper presents a transducer design of the hollow cylinder type designed to minimize transmission multipath and the need for channel equalization over short acoustic communication distances in shallow water. Operating at 750 kHz, the half-maximum envelope of the main lobe is approximately 3 degrees. The transducer was incorporated into a low-complexity modem system in which it acted as both transmitter and receiver. At-sea testing indicated that the system is capable of operating over horizontal distances of 5m without evidence of multipath distortion. The system was also found to be effective as an omnidirectional transmitter/receiver in the 10-60 kHz band.

TI Dependence of optimal spacing on applied field in ungated field emitter arrays SO AIP ADVANCES LA English DT Article ID CARBON NANOTUBES; VACUUM MICROELECTRONICS; MICROWAVE-AMPLIFIERS; EMISSION PROPERTIES; CATHODES; FILMS; CONES AB In ungated field emitter arrays, the field enhancement factor beta of each emitter tip is reduced below the value it would have in isolation due to the presence of adjacent emitters, an effect known as shielding or screening. Reducing the distance b between emitters increases the density of emission sites, but also reduces the emission per site, leading to the existence of an optimal spacing that maximizes the array current. Most researchers have identified that this optimal spacing is comparable to the emitter height h, although there is disagreement about the exact optimization. Here, we develop a procedure to determine the dependence of this optimal spacing on the applied electric field. It is shown that the nature of this dependence is governed by the shape of the beta(b) curve, and that for typical curves, the optimal value of the emitter spacing b decreases as the applied field increases.

TI Herschel spectroscopic observations of the compact obscured nucleus in Zw 049.057 SO ASTRONOMY & ASTROPHYSICS LA English DT Article DE ISM: molecules; galaxies: ISM; galaxies: individual: Zw 049.057; line: formation; infrared: galaxies; submillimeter: galaxies ID LUMINOUS INFRARED GALAXIES; ACTIVE GALACTIC NUCLEI; STAR-FORMING GALAXIES; WATER-VAPOR; NGC 4418; MOLECULAR OUTFLOWS; RADIATION PRESSURE; MARKARIAN 231; DISSOCIATIVE RECOMBINATION; ROTATIONAL-EXCITATION AB Context. The luminous infrared galaxy Zw 049.057 contains a compact obscured nucleus where a considerable amount of the galaxy's luminosity is generated. This nucleus contains a dusty environment that is rich in molecular gas. One approach to probing this kind of environment and to revealing what is hidden behind the dust is to study the rotational lines of molecules that couple well with the infrared radiation emitted by the dust. Aims. We probe the physical conditions in the core of Zw 049.057 and establish the nature of its nuclear power source (starburst or active galactic nucleus). Methods. We observed Zw 049.057 with the Photodetector Array Camera and Spectrometer (PACS) and the Spectral and Photometric Imaging Receiver (SPIRE) onboard the Herschel Space Observatory in rotational lines of H2O, (H2O)-O-18, OH, (OH)-O-18, and [O I]. We modeled the unresolved core of the galaxy using a spherically symmetric radiative transfer code. To account for the different excitation requirements of the various molecular transitions, we use multiple components and different physical conditions. Results. We present the full high-resolution SPIRE FTS spectrum of Zw 049.057, along with relevant spectral scans in the PACS range. We find that a minimum of two different components (nuclear and extended) are required in order to account for the rich molecular line spectrum of Zw 049.057. The nuclear component has a radius of 10-30 pc, a very high infrared surface brightness (similar to 10(14) L-circle dot kpc(-2)), warm dust (T-d > 100 K), and a very large H-2 column density (N-H2 = 10(24) - 10(25) cm(-2)). The modeling also indicates high nuclear H2O (similar to 5 x 10(-6)) and OH (similar to 4 x 10(-6)) abundances relative to H-2 as well as a low O-16/O-18-ratio of 50-100. We also find a prominent infall signature in the [O I] line. We tentatively detect a 500 km s(-1) outflow in the H2O 3(13) -> 2(02) line. Conclusions. The high surface brightness of the core indicates the presence of either a buried active galactic nucleus or a very dense nuclear starburst. The estimated column density towards the core of Zw 049.057 indicates that it is Compton-thick, making a buried X-ray source difficult to detect even in hard X-rays. We discuss the elevated H2O abundance in the nucleus in the context of warm grain and gas-phase chemistry. The H2O abundance is comparable to that of other compact (ultra-)luminous infrared galaxies such as NGC 4418 and Arp 220 - and also to hot cores in the Milky Way. The enhancement of O-18 is a possible indicator that the nucleus of Zw 049.057 is in a similar evolutionary stage as the nuclei of Arp 220 - and more advanced than NGC 4418. We discuss the origin of the extreme nuclear gas concentration and note that the infalling gas detected in [O I] implies that the gas reservoir in the central region of Zw 049.057 is being replenished. If confirmed, the H2O outflow suggests that the nucleus is in a stage of rapid evolution. C1 [Falstad, N.; Aalto, S.] Chalmers, Dept Earth & Space Sci, Onsala Space Observ, S-43992 Onsala, Sweden.

TI Temperature-Dependence of Lipid A Acyl Structure in Psychrobacter cryohalolentis and Arctic Isolates of Colwellia hornerae and Colwellia piezophila SO MARINE DRUGS LA English DT Article DE lipopolysaccharide; lipid A; lipid structure; mass spectrometry; psychrophile; homeoviscous adaptation ID CHLAMYDIA-TRACHOMATIS; ESCHERICHIA-COLI; SP NOV.; PSYCHROMONAS-MARINA; CARRIER PROTEIN; LIPOPOLYSACCHARIDE; ENDOTOXIN; BACTERIA; MOIETY; SHOCK AB Lipid A is a fundamental Gram-negative outer membrane component and the essential element of lipopolysaccharide (endotoxin), a potent immunostimulatory molecule. This work describes the metabolic adaptation of the lipid A acyl structure by Psychrobacter cryohalolentis at various temperatures in its facultative psychrophilic growth range, as characterized by MALDI-TOF MS and FAME GC-MS. It also presents the first elucidation of lipid A structure from the Colwellia genus, describing lipid A from strains of Colwellia hornerae and Colwellia piezophila, which were isolated as primary cultures from Arctic fast sea ice and identified by 16S rDNA sequencing. The Colwellia strains are obligate psychrophiles, with a growth range restricted to 15 degrees C or less. As such, these organisms have less need for fluidity adaptation in the acyl moiety of the outer membrane, and they do not display alterations in lipid A based on growth temperature. Both Psychrobacter and Colwellia make use of extensive single-methylene variation in the size of their lipid A molecules. Such single-carbon variations in acyl size were thought to be restricted to psychrotolerant (facultative) species, but its presence in these Colwellia species shows that odd-chain acyl units and a single-carbon variation in lipid A structure are present in obligate psychrophiles, as well.

TI Post-traumatic Stress Disorder Among Navy Health Care Personnel Following Combat Deployment SO MILITARY MEDICINE LA English DT Article ID AUSTRALIAN ARMY NURSES; ALLOSTATIC LOAD; BURNOUT; PROVIDERS; VIETNAM; ADAPTATION; DISEASE; ERRORS; WAR AB U.S. Navy health care personnel are exposed to an array of psychological stressors during combat deployment. This study compared rates of post-traumatic stress disorder (PTSD) among Navy health care personnel with nonhealth care personnel following single and repeated combat deployments. The study sample was identified from electronic records indicating deployment to Iraq, Kuwait, or Afghanistan, and included 3,416 heath care and 4,648 nonhealth care personnel. Health care personnel had higher PTSD rates and an increasing trend in PTSD rates across repeated deployments. After adjusting for combat exposure and other covariates, health care compared with nonhealth care personnel were more likely to be diagnosed with PTSD after one (odds ratio [OR] 2.02; 95% confidence interval [CI] 1.45-2.80), two (OR 2.27; 95% CI 1.26-4.08), and three deployments (OR 4.37; 95% CI 1.25-15.28). Exposure to wounded/dead friendly forces was associated with higher PTSD rates in health care personnel (OR 1.53; 95% CI 1.13-2.07). Health care personnel occupy a unique and essential role in current wartime operations, and are a high-risk group for PTSD. These findings suggest that further research is needed on the effects of caregiver stress, and refinements to postdeployment screening for health care personnel should be pursued.

TI Electron density dependence of impedance probe plasma potential measurements SO PHYSICS OF PLASMAS LA English DT Article ID RADIO-FREQUENCY PROBE; RESONANCE AB In earlier works, we used spheres of various sizes as impedance probes in demonstrating a method of determining plasma potential, phi(p), when the probe radius is much larger than the Debye length, lambda(D). The basis of the method in those works [Walker et al., Phys. Plasmas 13, 032108 (2006); ibid. 15, 123506 (2008); ibid. 17, 113503 (2010)] relies on applying a small amplitude signal of fixed frequency to a probe in a plasma and, through network analyzer-based measurements, determining the complex reflection coefficient, Gamma, for varying probe bias, V-b. The frequency range of the applied signal is restricted to avoid sheath resonant effects and ion contributions such that omega(pi) << omega << omega(pe), where omega(pi) is the ion plasma frequency and omega(pe) is the electron plasma frequency. For a given frequency and applied bias, both Re(Z(ac)) and Im(Z(ac)) are available from Gamma. When Re(Z(ac)) is plotted versus V-b, a minimum predicted by theory occurs at phi(p) [Walker et al., Phys. Plasmas 17, 113503 (2010)]. In addition, Im(Z(ac)) appears at, or very near, a maximum at phi(p). As n(e) decreases and the sheath expands, the minimum becomes harder to discern. The purpose of this work is to demonstrate that when using network analyzer-based measurements, Gamma itself and Im(Z(ac)) and their derivatives are useful as accompanying indicators to Re(Z(ac)) in these difficult cases. We note the difficulties encountered by the most commonly used plasma diagnostic, the Langmuir probe. Spherical probe data is mainly used in this work, although we present limited data for a cylinder and a disk. To demonstrate the effect of lowered density as a function of probe geometry, we compare the cylinder and disk using only the indicator Re(Z(ac)). (C) 2015 AIP Publishing LLC. C1 [Walker, D.

TI Measurements of electron density and temperature profiles in plasma produced by Nike KrF laser for laser plasma instability research SO REVIEW OF SCIENTIFIC INSTRUMENTS LA English DT Article ID 2-PLASMON DECAY; INHOMOGENEOUS PLASMAS; ACCURACY; FACILITY AB A grid image refractometer (GIR) has been implemented at the Nike krypton fluoride laser facility of the Naval Research Laboratory. This instrument simultaneously measures propagation angles and transmissions of UV probe rays (lambda = 263 nm, Delta t = 10 ps) refracted through plasma. We report results of the first Nike-GIR measurement on a CH plasma produced by the Nike laser pulse (similar to 1 ns FWHM) with the intensity of 1.1 x 10(15) W/cm(2). The measured angles and transmissions were processed to construct spatial profiles of electron density (n(e)) and temperature (T-e) in the underdense coronal region of the plasma. Using an inversion algorithm developed for the strongly refracted rays, the deployed GIR system probed electron densities up to 4 x 10(21) cm(-3) with the density scale length of 120 mu m along the plasma symmetry axis. The resulting n(e) and T-e profiles are verified to be self-consistent with the measured quantities of the refracted probe light. (C) 2015 Author(s).

Herein we develop high-aspect ratio (150:1), multiwalled carbon nanotube microarray membranes (CNT-MMs) for propulsive, MUV thrust generation by the decomposition of hydrogen peroxide (H2O2). The CNT-MMs are grown via chemical vapor deposition with diamond shaped pores (nominal diagonal dimensions of 4.5 x 9.0 gm) and subsequently decorated with urchin-like, platinum (Pt) nanoparticles via a facile, electroless, chemical deposition process. The Pt-CNT-MMs display robust, high catalytic ability with an effective activation energy of 26.96 Id mol(-1) capable of producing a thrust of 0.209 +/- 0.049 N from 50% [w/w] H2O2 decomposition within a compact reaction chamber of eight Pt-CNT-MMs in series.

Knowledge of the water affinity of graphene and its spatial variations is critically important as it can affect the graphene properties as well as the performance of graphene devices exposed to humidity. By employing chemical force microscopy with a probe rendered hydrophobic by functionalization with octadecyltrichlorosilane (OTS), the adhesion force between the probe and epitaxial graphene on SIC has been measured in deionized water. Owing to the hydrophobic attraction, a larger adhesion force was measured on 2LG Bernal-stacked domains of graphene surfaces, thus showing that 2LG is more hydrophobic than 1LG. Identification of 1LG and 2LG domains was achieved through Kelvin probe force microscopy and Raman spectral mapping. Approximate values of the adhesion force per OTS molecule have been calculated through contact area analysis. Furthermore, the contrast of friction force images measured in contact mode was reversed to the 1LG/2LG adhesion contrast, and its origin was discussed in terms of the likely water depletion over hydrophobic domains as well as deformation in the contact area between the atomic force microscope tip and 1LG.

PTE conjugation to QDs underwent extensive characterization including structural simulations, electrophoretic mobility shift assays, and dynamic light scattering to confirm orientational and ratiometric control over enzyme display which appears to be necessary for enhancement. PTE hydrolytic activity was then examined when attached to ca. 4 and 9 nm diameter QDs in comparison to controls of freely diffusing enzyme alone. The results confirm that the activity of the QD conjugates significantly exceeded that of freely diffusing PTE in both initial rate (similar to 4-fold) and enzymatic efficiency (similar to 2-fold). To probe kinetic acceleration, various modified assays including those with increased temperature, presence of a competitive inhibitor, and increased viscosity were undertaken to measure the activation energy and dissociation rates. Cumulatively, the data indicate that the higher activity is due to an acceleration in enzyme-product dissociation that is presumably driven by the markedly different microenvironment of the PTE-QD bioconjugate's hydration layer. This report highlights how a specific change in an enzymatic mechanism can be both identified and directly linked to its enhanced activity when displayed on a nanoparticle. Moreover, the generality of the mechanism suggests that it could well be responsible for other examples of nanoparticle-enhanced catalysis.

Unfortunately, this type of plan does not help those people who are unable to move themselves to the designated meeting locations. In the United States, according to the Post-Katrina Emergency Management Reform Act of 2006, state or local governments have the responsibility to coordinate evacuation plans for all populations. These include those with disabilities. However, few, if any, have plans in place for those who are mobility-challenged. The problem of evacuating mobility-challenged people from their individual locations in a short-notice disaster is a challenging combinatorial optimization problem. In order to develop the model and select a solution approach, we surveyed related literature. Based on our review, we formulate the problem and develop an Ant Colony Optimization (ACO) algorithm to solve it. We then test two different versions of the ACO algorithm on five stylized datasets with several different parameter settings.

A study group undergoing RAL utilizing sTBURG (group 1) was compared with a control group undergoing open surgery in the horizontal position (group 2), and laparoscopic cases in the horizontal position (group 3). An ophthalmologic examination including Snellen visual acuity, IOP, Humphrey Visual Field (HVF) 24-2 with standard Swedish Interactive Thresholding Algorithm, time domain optical coherence tomography (OCT), retinal nerve fiber layer (RNFL) analysis, pachymetry, and dilated fundus examination was conducted preoperatively and at 1 month postoperatively. IOP was measured intraoperatively at discrete time-points.Main Outcome Measures:IOP values, change in OCT RNFL thickness, HVF mean deviation, and HVF pattern standard deviation.Results:Baseline IOP (mm Hg) was similar, 13.73.2 for group 1 versus 15.3 +/- 3.2 for group 2 and 14.1 +/- 2.4 for group 3 (P=0.55). The IOP plateau from 60 minutes until case conclusion occurred at 29.9 mm Hg (95% confidence interval, 27.4-32.5), 19.9 mm Hg (95% confidence interval, 17.6-22.3), and 22.8 mm Hg (95% confidence interval, 20.2-25.4) for group 1, group 2, and group 3, respectively. There were no significant changes in OCT RNFL thickness, HVF mean deviation, and HVF pattern standard deviation.Conclusions:Significant elevations of IOP are experienced during robotic surgery utilizing sTBURG positioning in patients with healthy eyes, and we recommend a multidisciplinary approach in determining potential risk to those with known ocular disease who are candidates for these procedures.

TI CK-MM Polymorphism is Associated With Physical Fitness Test Scores in Military Recruits SO MILITARY MEDICINE LA English DT Article ID CREATINE-KINASE GENE; SKELETAL-MUSCLE; VARIANTS; EXERCISE; PERFORMANCE; STRENGTH AB Objective: Muscle-specific creatine kinase is thought to play an integral role in maintaining energy homeostasis by providing a supply of creatine phosphate. The genetic variant, rs8111989, contributes to individual differences in physical performance, and thus the purpose of this study was to determine if rs8111989 variant is predictive of Physical Fitness Test (PFT) scores in male, military infantry recruits. Methods: DNA was extracted from whole blood, and genotyping was performed in 176 Marines. Relationships between PFT measures (run, sit-ups, and pull-ups) and genotype were determined. Results: Participants with 2 copies of the T allele for rs8111989 variant had higher PFT scores for run time, pull-ups, and total PFT score. Specifically, participants with 2 copies of the TT allele (variant) (n = 97) demonstrated an overall higher total PFT score as compared with those with one copy of the C allele (n = 79) (TT: 250 +/- 31 vs. CC/CT: 238 +/- 31; p = 0.02), run score (TT: 82 +/- 10 vs. CC/CT: 78 +/- 11; p = 0.04) and pull-up score (TT: 78 +/- 11 vs. CC/CT: 65 +/- 21; p = 0.04) or those with the CC/CT genotype. Conclusion: These results demonstrate an association between physical performance measures and genetic variation in the muscle-specific creatine kinase gene (rs8111989).

TI Assessing the Biological Stability of a Terpene-Based Advanced Biofuel and Its Relationship to the Corrosion of Carbon Steel SO ENERGY & FUELS LA English DT Article ID SULFATE-REDUCING BACTERIA; ALTERNATIVE FUELS; ALKANE METABOLISM; ALPHA-PINENE; N-ALKANES; BIODEGRADATION; MONOTERPENES; DEGRADATION; DIESEL; DITERPENOIDS AB Energy-dense terpene biofuels have recently been recognized as renewable alternatives for high-density petroleum-derived fuels. While the physicochemical properties of terpene dimer fuel (TDF) have been well-documented, the propensity of these mixtures to undergo biodegradation and exacerbate the corrosion of the fuel infrastructure remains unknown. Coastal seawater/sediment incubations were amended with TDF or a blend of petroleum-derived hydrocarbons and incubated under strict anaerobic conditions. In some incubations, a model hydrocarbon-degrading sulfate-reducing bacterium (Desulfoglaeba alkanexedens, strain ALDC) was inoculated as a positive control. No increase in sulfate reduction or corrosion was observed in long-term experiments (300 days) relative to TDF-free controls when only seawater/sediment served as the inoculum. However, inoculation with the positive control organism and a mixture of C-6-C-12 n-alkanes increased both the sulfate reduction rate (95.2 +/- 5.2 mu M/day) and general corrosion, as determined by both coupon weight loss (27.9 +/- 1.6 mg) and the number of pits (495 +/- 62). The ratio of manganese (Mn)/weight loss (0.34) in incubations exhibiting coupon pitting was lower than those (0.53-0.68) showing only generalized coupon corrosion. Despite no indication for TDF biodegradation under all test conditions, the detection of a suite of alkylsuccinate metabolites attested to the anaerobic metabolism of the suite of n-alkanes when strain ALDC and the hydrocarbons served as amendments. These findings suggest that TDF is resistant to biodegradation and will not exacerbate the corrosion of carbon steel. If used in combination with petroleum hydrocarbons, the degree of metal corrosion would be that expected as a result of labile fuel components. However, the relatively recalcitrant nature of TDF might pose other risks if released to the environment and, thus, warrants further study.

The association of sexual trauma with health and occupational outcomes was investigated using longitudinal data from the Millennium Cohort Study. Of 13,001 U.S. service women, 1,364 (10.5%) reported recent sexual harassment and 374 (2.9%) recent sexual assault. Women reporting recent sexual harassment or assault were more likely to report poorer mental health: OR = 1.96, 95% CI [1.71, 2.25], and OR = 3.45, 95% CI [2.67, 4.44], respectively. They reported poorer physical health: OR = 1.39, 95% CI [1.20, 1.62], and OR = 1.39, 95% CI [1.04, 1.85], respectively. They reported difficulties in work/activities due to emotional health: OR = 1.80, 95% CI [1.59, 2.04], and OR = 2.70, 95% CI [2.12, 3.44], respectively. They also reported difficulties with physical health: OR = 1.55, 95% CI [1.37, 1.75], and OR = 1.52 95% CI [1.20, 1.91], respectively, after adjustment for demographic, military, health, and prior sexual trauma characteristics. Recent sexual harassment was associated with demotion, OR = 1.47, 95% CI [1.12, 1.93]. Findings demonstrated that sexual trauma represents a potential threat to military operational readiness and draws attention to the importance of prevention strategies and services to reduce the burden of sexual trauma on military victims.

TI Modifying Surface Energy of Graphene via Plasma-Based Chemical Functionalization to Tune Thermal and Electrical Transport at Metal Interfaces SO NANO LETTERS LA English DT Article DE Graphene; contacts; functionalization; thermal boundary conductance; contact resistivity ID SINGLE-LAYER; TRANSISTORS; CONTACTS; DEVICES; FILMS; RESISTANCE AB The high mobility exhibited by both supported and suspended graphene, as well as its large in-plane thermal conductivity, has generated much excitement across a variety of applications. As exciting as these properties are, one of the principal issues inhibiting the development of graphene technologies pertains to difficulties in engineering high-quality metal contacts on graphene. As device dimensions decrease, the thermal and electrical resistance at the metal/graphene interface. plays a dominant role in degrading overall performance. Here we demonstrate the use of a low energy, electron-beam plasma to functionalize graphene with oxygen, fluorine, and nitrogen groups, as a method to tune the thermal and electrical transport properties across gold-single layer graphene (Au/SLG) interfaces. We find that while oxygen and nitrogen groups improve the thermal boundary conductance (h(K)) at the interface, their presence impairs electrical transport leading to increased contact resistance (rho(C)). Conversely, functionalization with fluorine has no impact on h(K) yet rho(C) decreases with increasing coverage densities. These findings indicate exciting possibilities using plasma-based chemical functionalization to tailor the thermal and electrical transport properties of metal/2D material contacts.

When the N/Nb flux ratios are greater than one, the most critical parameter for high-quality beta-Nb2N is the substrate temperature. The X-ray characterization of films grown between 775 and 850 degrees C demonstrates beta-Nb2N phase formation. The (0002) and (21 (3) over bar1) X-ray diffraction measurements of a beta-Nb2N film grown at 850 degrees C reveal a 0.68% lattice mismatch to the 6H-SiC substrate. This suggests that beta-Nb2N can be used for high-quality metal/semiconductor heterostructures that cannot be fabricated at present. (C) 2015 The Japan Society of Applied Physics C1 [Katzer, D.

TI Predicting and managing heat dissipation from a neural probe SO BIOMEDICAL MICRODEVICES LA English DT Article DE Neural probe thermalmanagement; Heated neural probe; Neuron photostimulation; Bioheat equation; Heat transfer in neural tissue ID STIMULATION; BRAIN AB Light stimulating neural probes are rapidly increasing our understanding of neural pathways. Relocating the externally coupled light source to the probe tip has the potential to dramatically improve the flexibility of the technique. However, this approach would generate heat within the embedded probe where even minor temperature excursions could easily damage tissues under study. A COMSOL model was used to study the thermal effects of these heated probes in the brain including blood perfusion and metabolic heating, and to investigate the effect of passive methods for improving heat dissipation. The probe temperature initially decreases with insertion depth, and then becomes steady. Extending the probe beyond the heated region has a similar effect, while increasing the size of the heated region steadily decreases the probe temperature. Increasing the thermal conductivity of the probe promotes spreading, decreasing the probe temperature. The effects of insertion depth and probe power dissipation were experimentally tested with a microfabricated, heated mock neural probe. The heated probe was tested in 0.65 % agarose gel at room temperature and in ex vivo cow brain at body temperature. The thermal resistance between the probe and the neural tissue or agarose gel was determined at a range of insertion depths and compared to the COMSOL model.

The effects of voltammetric cycle number, BPB concentration, and pH on film thickness, density, optical absorption, and electrochemical susceptibility were evaluated, and favorable deposition conditions were identified. Quantitative measurement of the film mass via quartz crystal microbalance enabled determination of the molar volume and revealed a strong dependence of film density with deposition pH. Finally, electrochemical control of the optical properties of BPB films was demonstrated via in situ spectroelectrochemistry. We believe this is the first demonstration of electropolymerization of pure BPB on Au, and thus the first demonstration of poly(BPB) as an electrochemically switchable optical coating.

The implementation of gas puffs as a copious source of X-rays has encountered major challenges, such as disruptive instabilities and the quest for long implosion times. During nearly four decades of experimental and theoretical efforts, those challenges have been successfully met to a great extent. This success is a result of the efforts of a large number of researchers. Today, the gas-puff Z-pinch has evolved into a powerful source of X-rays and neutrons, and is fielded on multi-Mega-Ampere generators. The basic force imploding a pinch is straightforward, but the operation of a gas puff requires specialized hardware and a thorough understanding of the radiation physics involves magnetohydrodynamics coupled with nonequilibrium ionization kinetics. The goal of this review is to document the experiments and theory that have led to the success of the gas puff as a K-shell X-ray and neutron source. Consequently, this review takes a historical approach to the covered material, but also provides a broad introduction to relevant scientific concepts.

As higher current generators become available, Z-pinches incorporate increasingly larger masses of plasma and are nearly always optically thick to some or most of the photons that they produce. Understanding and modeling the transport of this radiation is an important element in attaining an overall picture of the physics of Z-pinches and in optimizing their properties for applications. This paper focuses on the aspects of radiation transport that are most relevant to the Z-pinch environment. The topics covered include: theory of radiation transport and its strengths and limitations, sources of opacity in Z-pinches, requirements for local thermodynamic equilibrium in the presence of opacity, transition to the blackbody limit, and Z-pinch experiments that demonstrate the effects of radiation transport.

TI 2-D RMHD Modeling Assessment of Current Flow, Plasma Conditions, and Doppler Effects in Recent Z Argon Experiments SO IEEE TRANSACTIONS ON PLASMA SCIENCE LA English DT Article DE Collisional radiative equilibrium; Doppler effects; K-shell radiation ID PHOTON-ESCAPE PROBABILITIES; RADIATION TRANSPORT; Z MACHINE; EQUATION; CODE AB By varying current-loss circuit parameters, the Mach2-tabular collisional radiative equilibrium 2-D radiation magnetohydrodynamic model was tuned to reproduce the radiative and electrical properties of three recent argon gas-puff experiments (same initial conditions) performed on the Z machine at Sandia National Laboratories. The model indicates that there were current losses occurring near or within the diode region of the Z machine during the stagnation phase of the implosion. The "good" simulation reproduces the experimental K-shell powers, K-shell yields, total powers, percentage of emission radiated in a lines, size of the K-shell emission region, and the average electron temperature near the time-of-peak K-shell power. The calculated atomic populations, ion temperatures, and radial velocities are used as input to a detailed multifrequency ray-trace radiation transport model that includes the Doppler effect. This model is employed to construct time-, space-, and energy-resolved synthetic spectra. The role the Doppler effect likely plays in the experiments is demonstrated by comparing synthetic spectra generated with and without this effect. C1 [Thornhill, J.

Theory, numerical modeling, and experimental data suggest that an optimum exists corresponding to a tradeoff between the increase in radiating mass and the decrease in coupled current with increasing pinch height. A typical load height of 20 mm used on many previous Z wire-array X-ray sources is found to be near optimal for K-shell yield production in SS and copper implosions. Electrical data, pinhole imaging, and spectroscopy are used to study plasma conditions in wire-array z pinches corresponding to the variation in K-shell power and yield per unit length as the pinch height is changed from 12 to 24 mm.

TI Arctic Radiative Fluxes: Present-Day Biases and Future Projections in CMIP5 Models SO JOURNAL OF CLIMATE LA English DT Article ID COMMUNITY ATMOSPHERE MODEL; SEA-ICE ALBEDO; CLIMATE MODEL; POLAR AMPLIFICATION; CLOUDS; INSTRUMENT; SATELLITE; EXTENT; PHASE AB Radiative fluxes are critical for understanding the energy budget of the Arctic region, where the climate has been changing rapidly and is projected to continue to change. This work investigates causes of present-day biases and future projections of top-of-atmosphere (TOA) Arctic radiative fluxes in phase 5 of the Coupled Model Intercomparison Project (CMIP5). Compared to Clouds and the Earth's Radiant Energy System Energy Balanced and Filled (CERES-EBAF), CMIP5 net TOA downward shortwave (SW) flux biases are larger than outgoing longwave radiation (OLR) biases. The primary contributions to modeled TOA SW flux biases are biases in cloud amount and snow cover extent compared to the GCM-Oriented CALIPSO Cloud Product (CALIPSO-GOCCP) and the newly developed Making Earth System Data Records for Use in Research Environments (MEaSUREs) dataset, respectively (with most models predicting insufficient cloud amount and snow cover in the Arctic), and biases with sea ice albedo. Future projections (2081-90) with representative concentration pathway 8.5 (RCP8.5) simulations suggest increasing net TOA downward SW fluxes (+8 W m(-2)) over the Arctic basin due to a decrease of surface albedo from melting snow and ice, and increasing OLR (+6 W m(-2)) due to an increase in surface temperatures. The largest contribution to future Arctic net TOA downward SW flux increases is declining sea ice area, followed by declining snow cover area on land, reductions to sea ice albedo, and reductions to snow albedo on land. Cloud amount is not projected to change significantly. These results suggest the importance of accurately representing both the surface area and albedos of sea ice and snow cover as well as cloud amount in order to accurately represent TOA radiative fluxes for the present-day climate and future projections.

However, a climatology of the MJO, particularly with respect to the frequency of activity levels or of consecutive days at certain activity thresholds, does not yet exist. Thus, several climatological aspects of the MJO were developed in this study: 1) annual and 2) seasonal variability in MJO intensity, quantified using four defined activity categories (inactive, active, very active, and extremely active); 3) persistence in the above-defined four categories; 4) cycle length; and 5) low-frequency (decadal) variability. On an annual basis, MJO phases 1 and 2 occurred more often, and phase 8 occurred less often, than the other phases throughout the year. Notable seasonality was also found, particularly in the frequency of extremely active MJO in March-May (8% of days) compared with June-August (only 1% of days). The MJO was persistent in time and across intensity categories, and all activity categories the following day had at least an 80% chance of maintaining their amplitudes. Implications of this climatology are discussed, including length of complete MJO cycles (the shortest of which was 17 days) and correlations between MJO amplitude and atmospheric response.

Participants were 80 U.S. Navy members assigned to an Arleigh Burke-class destroyer anticipating an 8-month deployment after Operation Enduring Freedom/Operation Iraqi Freedom. The effect that the number of deployments had on perpetrating physical partner violence diminished as relationship satisfaction increased. Results suggest the importance of designing domestic violence intervention and treatment efforts toward those who report high levels of deployment and low relationship satisfaction.

In addition, the authors review briefly what is known about tropical cyclone intensification in the presence of vertical wind shear. The authors go on to examine two recent lines of research that seem to offer very different views to understanding the intensification problem. The first of these proposes a mechanism to explain rapid intensification in terms of surface pressure falls in association with upper-level warming accompanying outbreaks of deep convection. The second line of research explores the relationship between the contraction of the radius of maximum tangential wind and intensification in the classical axisymmetric convective ring model, albeit in an unbalanced framework. The authors challenge a finding of the second line of research that appears to cast doubt on a recently suggested mechanism for the spinup of maximum tangential wind speed in the boundary layera feature seen in observations. In doing so, the authors recommend some minimum requirements for a satisfactory explanation of tropical cyclone intensification.

Coherent spin precession in a Rashba effective magnetic field(1,2) in the channel of a spin field-effect transistor(3,4) and the spin Hall effect(5-7) are the two most compelling topics in this area. Here, we combine these effects to provide a direct demonstration of the ballistic intrinsic spin Hall effect(8) and to demonstrate a technique for an all-electric measurement of the Datta-Das(3) conductance oscillation, that is, the oscillation in the source-drain conductance due to spin precession. Our hybrid device has a ferromagnet electrode as a spin injector and a spin Hall detector. Results from multiple devices with different channel lengths map out two full wavelengths of the Datta-Das oscillation. We also use the original Datta-Das technique with a single device of fixed length and measure the channel conductance as the gate voltage is varied. Our experiments show that the ballistic spin Hall effect can be used for efficient injection or detection of spin polarized electrons, thereby enabling the development of an integrated spin transistor.

The test uses the recently developed ensemble Kalman filter (EnKF) at the Naval Research Laboratory (NRL) for mesoscale data assimilation with the U.S. Navy's mesoscale numerical weather prediction model. Experiments are performed for a period of 6 days with a continuous update cycle of 12 h. Results from the experiments show remarkable improvements in both the ensemble analyses and forecasts with TES compared to those without. The improvements in the EnKF analyses by TES are very similar across the model's three nested grids of 45-, 15-, and 5-km grid spacing, respectively. This study demonstrates the usefulness of the TES method for ensemble-based data assimilation when the ensemble size cannot be sufficiently large because of operational constraints in situations where a time-critical environment assessment is needed or the computational resources are limited.

Escherichia coli (E. coli), Citrobacter koseri (C. koseri), Citrobacter braakii (C. braakii), and Bacillus cereus (B. cereus) were grown to logarithmic and stationary phases in nutrient broth and brain heart infusion broth. Resonance Raman spectra of bacteria were obtained at multiple wavelengths between 220 and 260 nm; a range that encompasses the resonance frequencies of cellular constituents. We find that spectra of the same bacterial species exhibit differences due to both growth condition and growth phase, but the larger differences reflect changes due to growth phase. The differences in the Raman spectra correlate with genetic differences among the species. Using a Pearson correlation based algorithm, we achieve successful identification of these bacteria in 83% of the cases.

PABA/NO has proven active in several cancer models in vitro and in vivo, but its tendency to be metabolized via a variety of pathways, some that generate inactive metabolites and hydrolysis products, limits its potential as a drug. Here we show that a simple replacement of cyano for nitro at the 4 position to give compound 4b ('p-cyano-PABA/NO') has the dual effect of slowing the undesired side reactions while enhancing the proportion of NO release and arylating activity on catalysis by GSTP1. Compound 4b showed increased resistance to hydrolysis and uncatalyzed reaction with GSH, along with a more favorable product distribution in the presence of GSTP1. It also showed significant proapoptotic activity. The data suggest p-cyano-PABA/NO to be a more promising prodrug than PABA/NO, with better selectivity toward cancer cells. Published by Elsevier Ltd.

It postulates that uncertainty is a guide to improbability. In its computer implementation, an intuitive system 1 simulates evidence in mental models and forms analog non-numerical representations of the magnitude of degrees of belief. This system has minimal computational power and combines evidence using a small repertoire of primitive operations. It resolves the uncertainty of divergent evidence for single events, for conjunctions of events, and for inclusive disjunctions of events, by taking a primitive average of non-numerical probabilities. It computes conditional probabilities in a tractable way, treating the given event as evidence that may be relevant to the probability of the dependent event. A deliberative system 2 maps the resulting representations into numerical probabilities. With access to working memory, it carries out arithmetical operations in combining numerical estimates. Experiments corroborated the theory's predictions. Participants concurred in estimates of real possibilities. They violated the complete joint probability distribution in the predicted ways, when they made estimates about conjunctions: P(A), P(B), P(A and B), disjunctions: P(A), P(B), P(A or B or both), and conditional probabilities P(A), P(B), P(B|A). They were faster to estimate the probabilities of compound propositions when they had already estimated the probabilities of each of their components. We discuss the implications of these results for theories of probabilistic reasoning. C1 [Khemlani, Sangeet S.] Naval Res Lab, Navy Ctr Appl Res Artificial Intelligence, Washington, DC 20375 USA.

Unlike whole-file hashing, hash-based carving can identify files that are fragmented, files that are incomplete, or files that have been partially modified. Previous efforts at hash-based carving have looked for evidence of a single file or a few files. We attempt hash-based carving with a target file database of roughly a million files and discover an unexpectedly high false identification rate resulting from common data structures in Microsoft Office documents and multimedia files. We call such blocks "non-probative blocks." We present the HASH-SETS algorithm that can determine the presence of files, and the HASH-RUNS algorithm that can reassemble files using a database of file block hashes. Both algorithms address the problem of non-probative blocks and provide results that can be used by analysts looking for target data on searched media. We demonstrate our technique using the bulk_extractor forensic tool, the hashdb hash database, and an algorithm implementation written in Python. Published by Elsevier Ltd on behalf of DFRWS.

The MIM nanostructure consists of patterned gold squares with systematically varying size and period atop a thin aluminum nitride dielectric layer on a thick gold film. Both the transverse-electric (TE) slab-waveguide mode and the transverse-magnetic (TM) surface plasmon-polariton mode can be excited in the nanostructure. Grating coupling of the incident light into nonlocalized traveling waves is found from electromagnetic field patterns and from the linear dispersion of the absorption modes with period. A localized mode strengthens the near-IR absorption band for small square sizes, and the resonance shifts to red for large square sizes.

Foelsch, Stefan TI Gating a single-molecule transistor with individual atoms SO NATURE PHYSICS LA English DT Article ID SCANNING TUNNELING MICROSCOPE; FRANCK-CONDON BLOCKADE; QUANTUM DOTS; SEMICONDUCTOR SURFACE; ORGANIC-MOLECULE; JUNCTIONS; BARRIER AB Transistors, regardless of their size, rely on electrical gates to control the conductance between source and drain contacts. In atomic-scale transistors, this conductance is sensitive to single electrons hopping via individual orbitals(1,2). Single-electron transport in molecular transistors has been previously studied using top-down approaches to gating, such as lithography and break junctions(1,3-11). But atomically precise control of the gate-which is crucial to transistor action at the smallest size scales-is not possible with these approaches. Here, we used individual charged atoms, manipulated by a scanning tunnelling microscope(12), to create the electrical gates for a single-molecule transistor. This degree of control allowed us to tune the molecule into the regime of sequential single-electron tunnelling, albeit with a conductance gap more than one order of magnitude larger than observed previously(8,11,13,14). This unexpected behaviour arises from the existence of two different orientational conformations of the molecule, depending on its charge state. Our results show that strong coupling between these charge and conformational degrees of freedom leads to new behaviour beyond the established picture of single-electron transport in atomic-scale transistors.

TI Mass-modulation schemes for a class of wave energy converters: Experiments, models, and efficacy SO OCEAN ENGINEERING LA English DT Article DE Ocean wave energy converter; Energy harvesting; Piecewise-smooth dynamical systems ID OSCILLATING BODIES; DYNAMICAL-SYSTEMS; POWER ABSORPTION; OPTIMIZATION; VIBRATION; SHAPE AB In a recent series of works, mass-modulation schemes have been proposed for a class of ocean wave energy converter (WEC). The goal of the schemes is to improve the energy harvesting capabilities of these devices by taking advantage of the ambient water. However this improvement comes at the cost of increased system complexity and possible impulse loadings at the instances where the mass changes. In the present work, experimental results for a pair of these schemes are presented and one of them is shown to be effective in increasing the energy harvesting potential of a WEC. Building and testing prototype WECs are costly and challenging and so, in order to examine as wide a range of parameters and designs as possible, a detailed two degree-of-freedom model is developed for a WEC equipped with a mass-modulation scheme. Numerical analysis of the model also shows the potential benefits of the mass-modulation scheme. Published by Elsevier Ltd.

Background As part of the White House Military Office, PEOC personnel historically worked a 12-hr Panama watch schedule. Personnel reported experiencing chronic insufficient and disrupted sleep patterns and sought advice for improving their watchstanding schedule. Method Participants (N= 14 active-duty military members, ages 29 to 42 years) completed the Profile of Mood State (POMS) three times: before, during, and after switching to the alternative schedule with 5-hr sleep periods built into their workday. Participants completed a poststudy questionnaire to assess individual schedule preferences. Sleep was measured actigraphically, supplemented by activity logs. Results As indicated by POMS scores, mood improved significantly on the new schedule. Although average total sleep amount did not change substantively, the timing of sleep was more consistent on the new schedule, resulting in better sleep hygiene. PEOC personnel overwhelmingly preferred the new schedule, reporting not only that they felt more rested but that the new schedule was more conducive to the demands of family life. Conclusions Demands of family life and time spent commuting were found to be critical factors for acceptance of the alternative schedule. This new schedule will be most effective if personnel adhere to the scheduled rest periods assigned during their 24-hr duty. Application A successful schedule should avoid conflicts between social life and operational demands. Results may lead to changes in the work schedules of other departments with similar 24/7 responsibilities.

Linear stability analysis and nonlinear BOUT++ simulations demonstrate that electromagnetic effects in high temperature or high beta plasmas suppress the resistive drift wave turbulence in the blob when resistivity drops below a certain value. In the course of blob's motion in the SQL its temperature is reduced, which leads to enhancement of resistive effects, so the blob can switch from electromagnetic to electrostatic regime, where resistive drift wave turbulence become important. It is found that inhomogeneity of magnetic curvature or plasma pressure along the filament length leads to bending of the high-beta blob filaments. This is caused by the increase of the propagation time of plasma current (Alfven time) in higher-density plasma. The effects of sheath boundary conditions on the part of the blob away from the boundary are also diminished by the increased Alfven time. (C) 2014 Elsevier B.V. All rights reserved.

TI Liver sharing and organ procurement organization performance under redistricted allocation SO LIVER TRANSPLANTATION LA English DT Article ID GEOGRAPHIC DISPARITIES; UNITED-STATES; WAITING-LIST; TRANSPLANTATION; ACCESS; RATES AB Concerns have been raised that optimized redistricting of liver allocation areas might have the unintended result of shifting livers from better-performing to poorer-performing organ procurement organizations (OPOs). We used liver simulated allocation modeling to simulate a 5-year period of liver sharing within either 4 or 8 optimized districts. We investigated whether each OPO's net liver import under redistricting would be correlated with 2 OPO performance metrics (observed to expected liver yield and liver donor conversion ratio), along with 2 other potential correlates (eligible deaths and incident listings above a Model for End-Stage Liver Disease score of 15). We found no evidence that livers would flow from better-performing OPOs to poorer-performing OPOs in either redistricting scenario. Instead, under these optimized redistricting plans, our simulations suggest that livers would flow from OPOs with more-than-expected eligible deaths toward those with fewer-than-expected eligible deaths and that livers would flow from OPOs with fewer-than-expected incident listings to those with more-than-expected incident listings; the latter is a pattern that is already established in the current allocation system. Redistricting liver distribution to reduce geographic inequity is expected to align liver allocation across the country with the distribution of supply and demand rather than transferring livers from better-performing OPOs to poorer-performing OPOs.

The model did not assimilate any data; instead, weak relaxation of temperature and salinity was implemented to keep the model stable in the long-term simulations. In this study, the skill of the IORM in simulating physical states in the IO was evaluated. Basin-scale surface circulation and cross-sectional transports were compared to observations, which demonstrated that the model replicated most of the observed features with reasonably good accuracy. Consistency and biases in the upper ocean temperature, salinity, and mixed layer depth were also analyzed. Lastly, the seasonality in the IO, its response to monsoonal forcing, and the evolution and dynamics of surface and subsurface dipole events were examined. The IORM reproduced most of the dynamic features including Ekman pumping, wave propagation, and climate variability at both annual and interannual time scales. The internal ocean dynamics and behavior of the modeled sea surface temperature anomaly (SSTA) suggest a coupled ocean/atmosphere instability that will require further research, including sensitivity experiments to realize improvements in model parameterization.

We used locations from 54 bowhead whales, obtained by satellite telemetry between 2006 and 2012, to define areas of concentrated use, termed "core-use areas". We identified six primary core-use areas and describe the timing of use and physical characteristics (oceanography, sea ice, and winds) associated with these areas. In spring, most whales migrated from wintering grounds in the Bering Sea to the Cape Bathurst polynya, Canada (Area 1), and spent the most time in the vicinity of the halocline at depths <75 m, which are within the euphotic zone, where calanoid copepods ascend following winter diapause. Peak use of the polynya occurred between 7 May and 5 July; whales generally left in July, when copepods are expected to descend to deeper depths. Between 12 July and 25 September, most tagged whales were located in shallow shelf waters adjacent to the Tuktoyaktuk Peninsula, Canada (Area 2), where wind-driven upwelling promotes the concentration of calanoid copepods. Between 22 August and 2 November, whales also congregated near Point Barrow, Alaska (Area 3), where east winds promote upwelling that moves zooplankton onto the Beaufort shelf, and subsequent relaxation of these winds promoted zooplankton aggregations. Between 27 October and 8 January, whales congregated along the northern shore of Chukotka, Russia (Area 4), where zooplankton likely concentrated along a coastal front between the southeastward-flowing Siberian Coastal Current and northward-flowing Bering Sea waters. The two remaining core-use areas occurred in the Bering Sea: Anadyr Strait (Area 5), where peak use occurred between 29 November and 20 April, and the Gulf of Anadyr (Area 6), where peak use occurred between 4 December and 1 April; both areas exhibited highly fractured sea ice. Whales near the Gulf of Anadyr spent almost half of their time at depths between 75 and 100 m, usually near the seafloor, where a subsurface front between cold Anadyr Water and warmer Bering Shelf Water presumably aggregates zooplankton. The amount of time whales spent near the seafloor in the Gulf of Anadyr, where copepods (in diapause) and, possibly, euphausiids are expected to aggregate provides strong evidence that bowhead whales are feeding in winter. The timing of bowhead spring migration corresponds with when zooplankton are,expected to begin their spring ascent in April. The core-use areas we identified are also generally known from other studies to have high densities of whales and we are confident these areas represent the majority of important feeding areas during the study (2006-2012). Other feeding areas, that we did not detect, likely existed during the study and we expect core-use area boundaries to shift in response to changing hydrographic conditions. (C) 2014 The Authors.

TI Variability in normal-incidence acoustic response in shallow-water marine sediments SO CONTINENTAL SHELF RESEARCH LA English DT Article DE Marine sediment classification; Sediment variability; Acoustic variability; Normal-incidence ID PROPERTY VARIABILITY; CONTINENTAL-MARGIN; CLASSIFICATION; FLUCTUATIONS; POROSITY; DENSITY; OCEAN AB Lateral variations in mass properties of sediments (grain density, porosity, and composition) occur at many spatial scales in all types of sediments. Sediment bulk properties determine elasticity and density and, therefore, the degree of acoustic response. Variations in properties and processes limit the potential of using acoustic response to differentiate sediment types. Small changes in one or more properties can produce a wide variation in the acoustic response, and empirical curve fitting most often serves as models for these relationships. Sedimentary data and acoustic variability at 30 and 50 kHz from three sites in the Mississippi Sound (Lambert et al., 2002) have been further analyzed and compared for the available Shepard sediment classes. Initial observations revealed trends in acoustic variability based on sediment classification. Clustering techniques were used to estimate the central tendency of the sparse set of geoacoustic measurements based on selected combinations of geotechnical parameters. The group-averaged sediment properties (geotechnical, granulometric, and geoacoustical) partially correlate with the acoustic coefficient of variation of the normal-incidence ping-ensemble 50 kHz response. Changes in acoustic fluctuations at 30 and 50 kHz strongly correlate with water content and compositional variations, and are consistent with volume variability and scattering.

A prospective longitudinal cohort study of influenza virus infection in 800 adults conducted during 2008-2010 in KPP suggested that subclinical or mild H5N1 infections had occurred among this adult cohort. However, this study was conducted after the peak of H5N1 activity in KPP. Coincidentally, banked serum samples were available from a prospective longitudinal cohort study of primary school children who had undergone active surveillance for febrile illnesses from 2004 to 2007 and lived in the same district of KPP as the adult cohort. Objectives: We sought to investigate whether subclinical or mild H5N1 infections had occurred among KPP residents during the peak of H5N1 activity from 2004 to 2006. Study design: H5N1 microneutralization (MN) assay was performed on banked serum samples from a prospective longitudinal cohort study of primary school children who had undergone active surveillance for febrile illnesses in KPP. Annual blood samples collected from 2004 to 2006 from 251 children were selected based on the criteria that they lived in villages with documented H5N1 infection. Result: No H5N1 neutralizing antibodies were detected in 753 annual blood samples from 251 children. Conclusion: During 2004-2006, very few subclinical or mild H5N1 infections occurred in KPP. Elevated H5N1MN titers found in the adult cohort in 2008 were likely due to cross-reactivity from other influenza virus subtypes highlighting the complexities in interpreting influenza serological data.

TI Inverse Thermal Analysis of Welds Using Multiple Constraints and Relaxed Parameter Optimization SO JOURNAL OF MATERIALS ENGINEERING AND PERFORMANCE LA English DT Article DE joining; modeling and simulation; thermal analysis; welding ID POOL SURFACE; FLUID-FLOW; HEAT; STEEL; MODEL AB Aspects of a methodology for inverse thermal analysis of welds are examined that provide for relaxed model-parameter optimization. These aspects are associated with the inherent insensitivity of temperature fields, obtained by inverse analysis, to local shape variations of constrained boundaries within these fields. The inverse analysis methodology is in terms of numerical-analytical basis functions for construction parametric temperature histories, which can be adopted as input data to computational procedures for further analysis. In addition, these parametric temperature histories can be used for inverse thermal analysis of welds corresponding to other process parameters or welding processes whose process conditions are within similar regimes. The inverse thermal analysis procedure provides for the inclusion of volumetric constraint conditions whose two-dimensional projections are mappings onto transverse cross sections of experimentally measured boundary conditions, such as solidification and transformation boundaries, and isothermal surfaces associated with thermocouple measurements. Issues concerning relaxed parameter optimization are discussed with respect to inverse thermal analysis of Ti-6Al-4V pulsed-mode laser welds using multiple constraint conditions.

TI All-Atom Molecular-Level Analysis of the Ballistic-Impact-Induced Densification and Devitrification of Fused Silica SO JOURNAL OF MATERIALS ENGINEERING AND PERFORMANCE LA English DT Article DE all-atom molecular-level analyses; fused silica; quantum-mechanical density functional theory (DFT) analyses; quartz; stishovite ID SODA-LIME GLASS; PENETRATION RESISTANCE; CARBON-NANOTUBES; AMORPHOUS SILICA; MATERIAL MODEL; FORCE-FIELD; PRESSURE; DYNAMICS; COMPASS; SYSTEMS AB All-atom molecular-level computations are carried out to infer the dynamic response and material microstructure/topology changes of fused silica subjected to ballistic impact by a hard projectile. The analysis was focused on the investigation of specific aspects of the dynamic response and of the microstructural changes such as the deformation of highly sheared and densified regions and the conversion of amorphous fused silica to SiO2 crystalline allotropic modifications (in particular, alpha-quartz and stishovite). The microstructural changes in question were determined by carrying out a post-processing atom-coordination procedure. This procedure suggested the formation of stishovite (and perhaps alpha-quartz) within fused silica during ballistic impact. To rationalize the findings obtained, the all-atom molecular-level computational analysis is complemented by a series of quantum-mechanics density functional theory (DFT) computations. The latter computations enable determination of the relative potential energies of the fused silica, alpha-quartz, and stishovite under ambient pressure (i.e., under their natural densities) as well as under imposed (as high as 50 GPa) pressures (i.e., under higher densities) and shear strains. In addition, the transition states associated with various fused-silica devitrification processes were identified. The results obtained are found to be in good agreement with their respective experimental counterparts. C1 [Grujicic, M.; Snipes, J.

TI Analysis and Comparison of Single-Crystal and Polycrystalline Nd:YAG, Scatter SO IEEE JOURNAL OF QUANTUM ELECTRONICS LA English DT Article DE Polycrystalline YAG; single crystal YAG; Nd:YAG; optical properties; scatterance; BSDF; TIS; Kubelka-Munk; anomalous diffraction; ADA ID ND-YAG CERAMICS; LASER; PERFORMANCE; SILICA AB The extrinsic scatterance properties of polycrystalline and single crystal Nd:YAG materials are reported. Materials include undoped, 1%, 1.5%, 2%, 4%, and 6% Nd doped polycrystalline YAG, and undoped and 1% Nd doped single crystal YAG. The motivation of this study is to determine the ideal material type, and doping percentage gain media for use in 0.946 mu m Nd: YAG lasers. In-plane bidirectional scatterance distribution function measurements are collected at multiple wavelengths from 0.405 mu m to 1.55 mu m for all samples. Scatterance data is fit to standard models and a total integrated scatter (TIS) for each sample at various wavelengths is determined. Using the TIS at multiple wavelengths, some conclusions on material quality and suitability are presented. A coated sphere anomalous diffraction (ADA) model is developed and applied to known sources of scatter in polycrystalline and single-crystal Nd: YAG. A Kubelka-Munk wavelength-dependant scatter coefficient model is developed using our ADA model. The model provides an accurate estimate of scatter at 0.946 mu m. A comparison of strengths and weaknesses of single-crystal and polycrystalline materials is presented. This comparison reveals a possible continuing problem with background scatter present in single-crystal YAG.

TI Non-planar mixed-mode growth of initially straight-fronted surface cracks, in cylindrical bars under tension, torsion and bending, using the symmetric Galerkin boundary element method-finite element method alternating method SO FATIGUE & FRACTURE OF ENGINEERING MATERIALS & STRUCTURES LA English DT Article DE fatigue crack growth; round bar; SGBEM-FEM alternating method; stress intensity factor ID STRESS INTENSITY FACTORS; ENERGY-RELEASE RATES; FATIGUED ROUND BARS; ANALYSES SGBEM-FEM; FRACTURE-MECHANICS; SINGULAR TRACTION; CIRCULAR BAR; EDGE CRACK; EQUATION; INTEGRALS AB In this paper, the stress intensity factor (SIF) variations along an arbitrarily developing crack front, the non-planar fatigue-crack growth patterns, and the fatigue life of a round bar with an initially straight-fronted surface crack, are studied by employing the 3D symmetric Galerkin boundary element method-finite element method (SGBEM-FEM) alternating method. Different loading cases, involving tension, bending and torsion of the bar, with different initial crack depths and different stress ratios in fatigue, are considered. By using the SGBEM-FEM alternating method, the SIF variations along the evolving crack front are computed; the fatigue growth rates and directions of the non-planar growths of the crack surface are predicted; the evolving fatigue-crack growth patterns are simulated, and thus, the fatigue life estimations of the cracked round bar are made. The accuracy and reliability of the SGBEM-FEM alternating method are verified by comparing the presently computed results to the empirical solutions of SIFs, as well as experimental data of fatigue crack growth, available in the open literature. It is shown that the current approach gives very accurate solutions of SIFs and simulations of fatigue crack growth during the entire crack propagation, with very little computational burden and human-labour cost. The characteristics of fatigue growth patterns of initially simple-shaped cracks in the cylindrical bar under different Modes I, III and mixed-mode types of loads are also discussed in detail.

TI Drag Forces on, and Deformation of, Closed Flexible Bags SO JOURNAL OF OFFSHORE MECHANICS AND ARCTIC ENGINEERING-TRANSACTIONS OF THE ASME LA English DT Article ID FILLED MEMBRANE; WAVES AB The use of closed flexible bags is among the suggestions considered as a potential way to expand the salmon production in Norway. Few ocean structures exist with large, heavily compliant submerged components, and there is presently limited existing knowledge about how aquaculture systems with flexible closed cages will respond to external sea loads. The flexibility and deformation of the bag are coupled to the hydrodynamic forces, and the forces and deformation will be dependent on the filling level of the bag. In order to get a better understanding of the drag forces on, and deformation of, such bags, experiments were conducted with a series of closed flexible bags. The bags were towed in a towing tank in order to simulate uniform current. Four different geometries were investigated, cylindrical, cubical, conical, and pyramidal, and the filling levels were varied between 70% and 120%. The main findings from the experiments were that the drag force was highly dependent on the filling level, and that the drag force increases with decreasing filling level. Comparing the drag force on a deflated bag with an inflated one showed an increase of up to 2.5 times.

Our objective was to determine if urinary incontinence is associated with disability in community-dwelling women 40 years and older. MethodsCross-sectional study among US women 40 years (n=4,458) from National Health and Nutrition Examination Surveys 2005-2010. We estimated the age-stratified weighted prevalence and factors independently associated with disability (Activities of Daily Living (ADLs), Instrumental Activities of Daily Living (IADLs), mobility, and functional limitations) in women with and without urinary incontinence while controlling for confounders of the association between disability and urinary incontinence. ResultsThe weighted prevalence of all disabilities was higher in women with urinary incontinence than women without urinary incontinence across most decades of life with the greatest difference in the prevalence of mobility disabilities: 40-49 years (12.1% vs. 7.0%), 50-59 years (17.0% vs. 9.2%), 60-69 years (28.3% vs. 19.8%), and 70+ years (43.8% vs. 33.0%, all P<0.05). On multivariable analysis, after controlling for the confounding effect of age, co-morbidities, and income-poverty ratio, urinary incontinence was weakly associated with disabilities. The adjusted odds ratio (95% confidence interval) of disabilities for urinary incontinence was ADL 1.96 (1.07, 3.58), IADL 1.18 (0.78, 1.78), mobility 1.26 (1.01, 1.56), and functional limitations 1.36 (1.07, 1.73). ConclusionsUrinary incontinence is weakly associated with disabilities and cannot be implicated as a cause of disability in community dwelling women. Neurourol. Urodynam. 34:539-543, 2015.

A procedure for the spatial enhancement of ocean color products, including chlorophyll and inherent optical properties (IOPs), is developed using a sharpened visible water-leaving radiance spectrum for the visible infrared imaging radiometer suite (VIIRS). A new approach for spectral sharpening is developed by utilizing the spatial covariance of the spectral bands for sharpening the M bands (412, 443,486, 551, 671 nm; 750-m resolution) with the I-1 band (645 nm; 375-m resolution). The spectral shape remains consistent by the use of a dynamic, wavelength-specific spatial resolution ratio that is weighted as a function of the relationship between proximate I- and M-band variance at each pixel. A comparison of bio-optical satellite products at 375-m and 750-m spatial resolution with in situ measurements of water leaving radiance and bio-optical properties show an improved capability of the VIIRS 375-m products in turbid and optically complex waters, such as the Chesapeake Bay and Mississippi River Plume.

They are characterized by Schrodinger wavefunctionals having support on 3-metrics of constant spatial scalar curvature, and thus contain two full physical field degrees of freedom in accordance with the Yamabe construction. These solutions are moreover Gaussians of minimum uncertainty and they are naturally associated with a rigged Hilbert space. In addition, in the limit the regulator is removed, exact 3-dimensional diffeomorphism and local gauge invariance of the solutions are recovered. (C) 2015 Published by Elsevier Inc.

TI Positron clouds within thunderstorms SO JOURNAL OF PLASMA PHYSICS LA English DT Article ID GAMMA-RAY FLASHES; RUNAWAY ELECTRON AVALANCHE; ATMOSPHERIC-PRESSURE; FEEDBACK MECHANISM; X-RAYS; DISCHARGES; BREAKDOWN; AIR; RADIATION; EMISSION AB We report the observation of two isolated clouds of positrons inside an active thunderstorm. These observations were made by the Airborne Detector for Energetic Lightning Emissions (ADELE), an array of six gamma-ray detectors, which flew on a Gulfstream V jet aircraft through the top of an active thunderstorm in August 2009. ADELE recorded two 511 keV gamma-ray count rate enhancements, 35 s apart, each lasting approximately 0.2 s. The enhancements, which were approximately a factor of 12 above background, were both accompanied by electrical activity as measured by a flat-plate antenna on the underside of the aircraft. The energy spectra were consistent with a source mostly composed of positron annihilation gamma rays, with a prominent 511 keV line clearly visible in the data. Model fits to the data suggest that the aircraft was briefly immersed in clouds of positrons, more than a kilometre across. It is not clear how the positron clouds were created within the thunderstorm, but it is possible they were caused by the presence of the aircraft in the electrified environment.

In this study however, the selection near the coast of East Asia is optimally from the Surface Velocity Program (SVP) data using the bin average method. Japan, Vietnam, Taiwan, and Philippines have suitable sites for the development of ocean current power generation. In these regions, the average current speeds reach 1.4,1.2,1.1, and 1.0 ms(-1) respectively. Vietnam has a better bottom topography to develop the current power generation. Taiwan and Philippines also have good conditions to build plants for generating ocean current power. Combined with the four factors of site selection (near coast, shallow seabed, stable flow velocity, and high flow speed), the waters near Vietnam is most suitable for the development of current power generation. Twelve suitable sites, located near coastlines of Vietnam, Japan, Taiwan, and Philippines, are identified for ocean current power generation. After the Kuroshio power plant being successfully operated in Taiwan, more current power plants can be built in these waters. (C) 2015 Elsevier Ltd. All rights reserved.

Variables tested included the impact of UV radiation, inclusion of hydrogen peroxide, catalyst treatment methods (oven treated and plasma torch treated) and type of the support. Results obtained for Orange II degradation indicated that active sites on carbon are more active for the catalytic decomposition of Orange II molecules, than metal sites. Oven-treated iron catalysts showed higher OII removal than catalysts prepared by plasma torch due to the fact that iron blocks carbon catalytic sites. XRD experiment on the non-active support allowed concluding that the oxidation state of Fe on the catalyst is not the main factor in the photocatalytic degradation of Orange II.

CA STAR Collaboration TI Long-range pseudorapidity dihadron correlations in d plus Au collisions at root S-NN=200 GeV SO PHYSICS LETTERS B LA English DT Article ID TIME PROJECTION CHAMBER; HEAVY-ION COLLISIONS; QUARK-GLUON PLASMA; P-PB COLLISIONS; ANGULAR-CORRELATIONS; ROOT-S(NN)=5.02 TEV; COLLECTIVE FLOW; PPB COLLISIONS; STAR; COLLABORATION AB Dihadron angular correlations in d + Au collisions at root S-NN = 200 GeV are reported as a function of the measured zero-degree calorimeter neutral energy and the forward charged hadron multiplicity in the Au-beam direction. A finite correlated yield is observed at large relative pseudorapidity (Delta eta) on the near side (i.e. relative azimuth Delta phi similar to 0). This correlated yield as a function of Delta eta appears to scale with the dominant, primarily jet-related, away-side (Delta phi similar to pi) yield. The Fourier coefficients of the Delta phi correlation, V-n = < cosn Delta phi >, have a strong Delta eta dependence. In addition, it is found that V-1 is approximately inversely proportional to the mid-rapidity event multiplicity, while V-2 is independent of it with similar magnitude in the forward (d-going) and backward (Au-going) directions.

TI Modeling the ionospheric impact of tsunami-driven gravity waves with SAMI3: Conjugate effects SO GEOPHYSICAL RESEARCH LETTERS LA English DT Article DE tsunami; gravity waves; ionosphere; conjugate effects ID ATMOSPHERE; EARTHQUAKE AB The Naval Research Laboratory first-principles ionosphere model SAMI3 is used to study the ionospheric effects associated with tsunami-driven gravity waves. Specifically, the Tohoku-Oki tsunami of 11 March 2011 is modeled. It is shown that gravity wave-induced variations in the neutral wind lead to plasma velocity variations both perpendicular and parallel to the geomagnetic field. Moreover, the electric field induced by the neutral wind perturbations can map to the conjugate hemisphere. Thus, electron density variations can be generated in both hemispheres which impact the total electron content (TEC) and 6300 angstrom airglow emission. It is found that the TEC exhibits variations of less than or similar to +/- 0.1 total electron content unit (1 TECU = 10(16) el m(-2)) and the 6300 angstrom airglow emission variation is up to similar to +/- 2.5% relative to the unperturbed background airglow.

TI Density perturbation theory SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID LINEAR-COMBINATION; FUNCTIONAL THEORY; 2ND DERIVATIVES; WAVE-FUNCTIONS; ENERGY; IMPLEMENTATION; EXPANSION; INTEGRALS; SOLIDS AB Despite the fundamental importance of electron density in density functional theory, perturbations are still usually dealt with using Hartree-Fock-like orbital equations known as coupled-perturbed Kohn-Sham (CPKS). As an alternative, we develop a perturbation theory that solves for the perturbed density directly, removing the need for CPKS. This replaces CPKS with a true Hohenberg-Kohn density perturbation theory. In CPKS, the perturbed density is found in the basis of products of occupied and virtual orbitals, which becomes ever more over-complete as the size of the orbital basis set increases. In our method, the perturbation to the density is expanded in terms of a series of density basis functions and found directly. It is possible to solve for the density in such a way that it makes the total energy stationary even if the density basis is incomplete. (C) 2015 AIP Publishing LLC.

In many cases, there are minimal differences between temporally and spatially coincident MODIS and VIIRS bio-optical products. However, due to factors such as atmospheric effects, sensor, and solar geometry differences, there are cases where the sensors' derived products do not compare favorably. When these cases occur, selected nLw values from one sensor can be used to vicariously calibrate the other sensor. Coincident VIIRS and MODIS scenes were used to test this cross-sensor calibration method. The VIIRS sensor was selected as the "base" sensor providing "synthetic" in situ nLw data for vicarious calibration, which computed new sensor gain factors used to reprocess the coincident MODIS scene. This reduced the differences between the VIIRS and MODIS bio-optical measurement. Chlorophyll products from standard and cross-sensor calibrated MODIS scenes were fused with the VIIRS chlorophyll product to demonstrate the ability for this cross-sensor calibration and product fusion method to remove atmospheric and cloud features. This cross-sensor calibration method can be extended to other current and future sensors. (C) The Authors. Published by SPIE under a Creative Commons Attribution 3.0 Unported License.

TI Electron Backscatter Diffraction Study of Hexagonal Boron Nitride Growth on Cu Single-Crystal Substrates SO ACS APPLIED MATERIALS & INTERFACES LA English DT Article DE boron nitride; 2-D; crystal orientation; EBSD; copper substrates; XPS ID CHEMICAL-VAPOR-DEPOSITION; GRAPHENE; MONOLAYER; COPPER; CU(100); SURFACE; OXYGEN AB Hexagonal boron nitride (h-BN) is an important material for the development of new 2D heterostructures. To enable this development, the relationship between crystal growth and the substrate orientation must be explored and understood. In this study, we simultaneously grew h-BN on different orientations of Cu substrates to establish the impact of substrate structure on the growth habit of thin h-BN layers. The substrates studied were a polycrystalline Cu foil, Cu(100), Cu(110), and Cu(111). Fourier transform grazing-incidence infrared reflection absorption spectroscopy (FT-IRRAS) was used to identify h-BN on copper substrates. X-ray photoelectron spectroscopy (XPS) was used to determine the effective thickness of the h-BN. Scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD) were used to measure the morphology of the films and postgrowth crystal structure of the Cu substrates, respectively. Combining the SEM and EBSD images allowed for the correlation between h-BN film coverage and the crystal structure of Cu. It was found that the growth rate was inversely proportional to the surface free energy of the Cu surface, with Cu(111) having the most h-BN surface coverage. The Cu foil predominately crystallized with a (100) surface orientation, and likewise had a film coverage very close to the Cu(100).

TI Increased Dietary Intake of Saturated Fatty Acid Heptadecanoic Acid (C17:0) Associated with Decreasing Ferritin and Alleviated Metabolic Syndrome in Dolphins SO PLOS ONE LA English DT Article ID BOTTLE-NOSED DOLPHINS; TYPE-2 DIABETES-MELLITUS; TURSIOPS-TRUNCATUS; INSULIN-RESISTANCE; DAIRY CONSUMPTION; FISH CONSUMPTION; ARACHIDONIC-ACID; SERUM FERRITIN; LIVER-DISEASE; IRON-OVERLOAD AB Similar to humans, bottlenose dolphins (Tursiops truncatus) can develop metabolic syndrome and associated high ferritin. While fish and fish-based fatty acids may protect against metabolic syndrome in humans, findings have been inconsistent. To assess potential protective factors against metabolic syndrome related to fish diets, fatty acids were compared between two dolphin populations with higher (n = 30, Group A) and lower (n = 19, Group B) mean insulin (11 +/- 12 and 2 +/- 5 mu IU/ml, respectively; P < 0.0001) and their dietary fish. In addition to higher insulin, triglycerides, and ferritin, Group A had lower percent serum heptadecanoic acid (C17:0) compared to Group B (0.3 +/- 0.1 and 1.3 +/- 0.4%, respectively; P < 0.0001). Using multivariate stepwise regression, higher percent serum C17:0, a saturated fat found in dairy fat, rye, and some fish, was an independent predictor of lower insulin in dolphins. Capelin, a common dietary fish for Group A, had no detectable C17:0, while pin-fish and mullet, common in Group B's diet, had C17:0 (41 and 67 mg/100g, respectively). When a modified diet adding 25% pinfish and/or mullet was fed to six Group A dolphins over 24 weeks (increasing the average daily dietary C17:0 intake from 400 to 1700 mg), C17:0 serum levels increased, high ferritin decreased, and blood-based metabolic syndrome indices normalized toward reference levels. These effects were not found in four reference dolphins. Further, higher total serum C17:0 was an independent and linear predictor of lower ferritin in dolphins in Group B dolphins. Among off the shelf dairy products tested, butter had the highest C17:0 (423mg/100g); nonfat dairy products had no detectable C17:0. We hypothesize that humans' movement away from diets with potentially beneficial saturated fatty acid C17:0, including whole fat dairy products, could be a contributor to widespread low C17:0 levels, higher ferritin, and metabolic syndrome.

TI The binary nature of PSR J2032+4127 SO MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY LA English DT Article DE binaries: eclipsing; stars: individual: MT91 213; stars: neutron; pulsars: individual: J2032+4127, Be stars; open clusters and associations: individual: Cyg OB2 ID GAMMA-RAY PULSARS; RADIO OBSERVATIONS; STARS; B1259-63; LAT; OB2 AB PSR J2032+4127 is a gamma-ray and radio-emitting pulsar which has been regarded as a young luminous isolated neutron star. However, its recent spin-down rate has extraordinarily increased by a factor of 2. We present evidence that this is due to its motion as a member of a highly-eccentric binary system with an similar to 15-M circle dot Be star, MT91 213. Timing observations show that, not only are the positions of the two stars coincident within 0.4 arcsec, but timing models of binary motion of the pulsar fit the data much better than a model of a young isolated pulsar. MT91 213, and hence the pulsar, lie in the Cyg OB2 stellar association, which is at a distance of only 1.4-1.7 kpc. The pulsar is currently on the near side of, and accelerating towards, the Be star, with an orbital period of 20-30 yr. The next periastron is well constrained to occur in early 2018, providing an opportunity to observe enhanced high-energy emission as seen in other Be-star binary systems. C1 [Lyne, A.

TI Clinical and imaging assessment of acute combat mild traumatic brain injury in Afghanistan SO NEUROLOGY LA English DT Article ID AMYLOID PRECURSOR PROTEIN; HEAD-INJURY; AXONAL INJURY; MILITARY PERSONNEL; CONCUSSION; BLAST; DEPRESSION; SPORTS; PERFORMANCE; MANAGEMENT AB Objective: To evaluate whether diffusion tensor imaging (DTI) will noninvasively reveal white matter changes not present on conventional MRI in acute blast-related mild traumatic brain injury (mTBI) and to determine correlations with clinical measures and recovery. Methods: Prospective observational study of 95 US military service members with mTBI enrolled within 7 days from injury in Afghanistan and 101 healthy controls. Assessments included Rivermead Post-Concussion Symptoms Questionnaire (RPCSQ), Post-Traumatic Stress Disorder Checklist Military (PCLM), Beck Depression Inventory (BDI), Balance Error Scoring System (BESS), Automated Neuropsychological Assessment Metrics (ANAM), conventional MRI, and DTI. Results: Significantly greater impairment was observed in participants with mTBI vs controls: RPCSQ (19.7 +/- 12.9 vs 3.6 +/- 7.1, p < 0.001), PCLM (32 +/- 13.2 vs 20.9 +/- 7.1, p < 0.001), BDI (7.4 +/- 6.8 vs 2.5 +/- 4.9, p < 0.001), and BESS (18.2 +/- 8.4 vs 15.1 +/- 8.3, p = 0.01). The largest effect size in ANAM performance decline was in simple reaction time (mTBI 74.5 +/- 148.4 vs control -11 +/- 46.6 milliseconds, p < 0.001). Fractional anisotropy was significantly reduced in mTBI compared with controls in the right superior longitudinal fasciculus (0.393 +/- 0.022 vs 0.405 +/- 0.023, p < 0.001). No abnormalities were detected with conventional MRI. Time to return to duty correlated with RPCSQ (r = 0.53, p < 0.001), ANAM simple reaction time decline (r = 0.49, p < 0.0001), PCLM (r = 0.47, p < 0.0001), and BDI (r = 0.36 p = 0.0005). Conclusions: Somatic, behavioral, and cognitive symptoms and performance deficits are substantially elevated in acute blast-related mTBI. Postconcussive symptoms and performance on measures of posttraumatic stress disorder, depression, and neurocognitive performance at initial presentation correlate with return-to-duty time. Although changes in fractional anisotropy are uncommon and subtle, DTI is more sensitive than conventional MRI in imaging white matter integrity in blast-related mTBI acutely.

TI HIGH SPATIAL RESOLUTION X-RAY SPECTROSCOPY OF THE IC 443 PULSAR WIND NEBULA AND ENVIRONS SO ASTROPHYSICAL JOURNAL LA English DT Article DE ISM: individual objects (G189.22+2.90, IC 443); ISM: supernova remnants; stars: neutron; X-rays: individual (CXOU J061705.3+222127); X-rays: ISM ID SUPERNOVA REMNANT IC-443; BOW-SHOCK NEBULAE; VELA PULSAR; EMISSION; ROTATION; SPECTRUM; JET AB Deep Chandra ACIS observations of the region around the putative pulsar, CXOU J061705.3+222127, in the supernova remnant (SNR) IC 443 reveal an similar to 5 '' radius ring-like structure surrounding the pulsar and a jet-like feature oriented roughly north-south across the ring and through the pulsar's location at 06(h)17(m)5(s).200 + 22 degrees 21' 27 ''.52 (J2000.0 coordinates). The observations further confirm that (1) the spectrum and flux of the central object are consistent with a rotation-powered pulsar, (2) the non-thermal spectrum and morphology of the surrounding nebula are consistent with a pulsar wind, and (3) the spectrum at greater distances is consistent with thermal emission from the SNR. The cometary shape of the nebula, suggesting motion toward the southwest, appears to be subsonic: There is no evidence either spectrally or morphologically for a bow shock or contact discontinuity; the nearly circular ring is not distorted by motion through the ambient medium; and the shape near the apex of the nebula is narrow. Comparing this observation with previous observations of the same target, we set a 99% confidence upper limit to the proper motion of CXOU J061705.3+222127 to be less than 44 mas yr(-1) (310 km s(-1) for a distance of 1.5 kpc), with the best-fit (but not statistically significant) projected direction toward the west.

The O-isotopic composition of the grain indicates an origin in a low-mass (similar to 2.2M(circle dot)), approximately solar metallicity red/asymptotic giant branch (RGB/AGB) star undergoing first dredge-up. The magnetite is a single crystal measuring 750 x 670 nm, is free of defects, and is stoichiometric Fe3O4. We hypothesize that the magnetite formed via oxidation of previously condensed Fe dust within the circumstellar envelope of its progenitor star. Using an empirically derived rate constant for this reaction, we calculate that such oxidation could have occurred over timescales ranging from approximately similar to 9000-500,000 years. This timescale is within the lifetime of estimates for dust condensation within RGB/AGB stars. C1 [Zega, Thomas J.] Univ Arizona, Lunar & Planetary Lab, Tucson, AZ 85721 USA.

In the most extreme case the Ar XIV line intensity relative to the Ca XIV intensity was 7 times the value expected from the photospheric abundance ratio, which is about 30 times the abundance of argon relative to calcium in active regions, i.e., the measured Ar/Ca abundance ratio is about 10 instead of 0.37 as in active regions. The Ar XIV and Ca XIV lines are formed near 3.4 MK and have very similar contribution functions. This is the first observation of the inverse FIP effect in the Sun. Other regions show increases of 2-3 over photospheric abundances, or just photospheric abundances. This phenomenon appears to occur rarely and only over small areas of flares away from the regions containing multi-million degree plasma, but more work is needed to quantify the occurrences and their locations. In the bright hot regions of flares the Ar/Ca abundance ratio is coronal, i.e., the same as in active regions. In this Letter we show three examples of the inverse FIP effect. C1 [Doschek, G.

With a median redshift of < z > = 0.22, the clusters found by Planck at z > 0.3 are proving to be exceptionally massive and/or disturbed systems. One notable Planck discovery at z = 0.645, PLCK G147.3-16.6, has an elongated core and hosts a radio halo, indicating it is likely in the process of merging. We present a 16 ''.5 resolution SZ observation of this high-z merger using the Goddard-IRAM Superconducting 2-Millimeter Observer, and compare it to X-ray follow-up observations with XMM-Newton. We find the SZ pressure substructure is offset from the core components seen in X-ray. We interpret this as possible line of sight temperature or density substructure due to the on-going merger.

TI Effects of magnetic field and pressure in magnetoelastic stress reconfigurable thin film resonators SO APPLIED PHYSICS LETTERS LA English DT Article ID BEAM RESONATORS; TUNING FORKS; SENSORS; MODEL AB Free-standing CoFe thin-film doubly clamped stress reconfigurable resonators were investigated as a function of magnetic field and pressure. A large uniaxial anisotropy resulting from residual uniaxial tensile stress, as revealed from magnetic hysteresis loops, leads to an easy magnetization axis aligned along the length of the beams. The quality factor of the driven resonator beams under vacuum is increased by 30 times, leading to an enhanced signal-to-noise ratio and a predicted reduction in the intrinsic magnetic noise by a factor of 6, potentially reaching as low as similar to 25 pT/root Hz at 1 Torr. Stress reconfigurable sensors operating under vacuum could thus further improve the limit of detection and advance development of magnetic field sensing technology. (C) 2015 AIP Publishing LLC.

Here, we report the observation of an unusual insulating state with an electrically insulating bulk that simultaneously yields bulk quantum oscillations with characteristics of an unconventional Fermi liquid. We present quantum oscillation measurements of magnetic torque in high-purity single crystals of the Kondo insulator SmB6, which reveal quantum oscillation frequencies characteristic of a large three-dimensional conduction electron Fermi surface similar to the metallic rare earth hexaborides such as PrB6 and LaB6. The quantum oscillation amplitude strongly increases at low temperatures, appearing strikingly at variance with conventional metallic behavior. C1 [Tan, B.

TI Zero-energy peak and triplet correlations in nanoscale superconductor/ferromagnet/ferromagnet spin valves SO PHYSICAL REVIEW B LA English DT Article ID LOCAL-DENSITY; FERROMAGNET; SUPERCONDUCTIVITY; STATES AB Using a self-consistent Bogoliubov-de Gennes approach, we theoretically study the proximity-induced density of states (DOS) in clean SFF spin valves with noncollinear exchange fields. Our results clearly demonstrate a direct correlation between the presence of a zero-energy peak (ZEP) in the DOS spectrum and the persistence of spin-1 triplet pair correlations. By systematically varying the geometrical and material parameters governing the spin valve, we point out experimentally optimal system configurations where the ZEPs are most pronounced, and which can be effectively probed via scanning tunneling microscopy. We complement these findings in the ballistic regime by employing the Usadel formalism in the full proximity limit to investigate their diffusive SFF counterparts. We determine the optimal normalized ferromagnetic layer thicknesses which result in the largest ZEPs. Our results can serve as guidelines in designing samples for future experiments.

The spectroscopic evidence points to the fact that monolayers of the molecule can be formed through the self-assembly process and the SERS data indicate that the monolayer attach to the silver surface through the nitrile groups. SERS spectroscopy was useful in determining the orientation of the monolayer as well as estimating its order. Deprotection the thiol group thereby terminating the tail of the molecule with a sulfur atom allowed for a selectively oriented monolayer to be formed which permanently bound the molecules to the surface preventing rearrangements. This orientation of AcSC(6)H(12)Q-3CNQ on silver a surface allowed the electron pairs of the nitrogen to be available for interaction with a second contact. Based on trigonometric tangent function calculations the tilt angle was calculated to be 38 for the protected molecule and 70 for the deprotected alkane thiol monolayer. (C) 2015 Elsevier Inc.

TI Stratified Sampling of Neighborhood Sections for Population Estimation: A Case Study of Bo City, Sierra Leone SO PLOS ONE LA English DT Article AB There is a need for better estimators of population size in places that have undergone rapid growth and where collection of census data is difficult. We explored simulated estimates of urban population based on survey data from Bo, Sierra Leone, using two approaches: (1) stratified sampling from across 20 neighborhoods and (2) stratified single-stage cluster sampling of only four randomly-sampled neighborhoods. The stratification variables evaluated were (a) occupants per individual residence, (b) occupants per neighborhood, and (c) residential structures per neighborhood. For method (1), stratification variable (a) yielded the most accurate re-estimate of the current total population. Stratification variable (c), which can be estimated from aerial photography and zoning type verification, and variable (b), which could be ascertained by surveying a limited number of households, increased the accuracy of method (2). Small household-level surveys with appropriate sampling methods can yield reasonably accurate estimations of urban populations.

TI The influence of magnetic field on electron beam generated plasmas SO JOURNAL OF PHYSICS D-APPLIED PHYSICS LA English DT Article DE electron beam; magnetic field; Boltzmann equation; plasma processing ID TRANSPORT; KINETICS; ARGON; COLUMN AB Magnetically confined argon plasma in a long cylindrical tube driven by an electron beam is studied experimentally and theoretically. Langmuir probes are used to measure the electron energy distribution function, electron density and temperature in plasmas generated by 2 keV, 10 mA electron beams in a 25 mTorr argon background for magnetic field strengths of up to 200 Gauss. The experimental results agree with simulations done using a spatially averaged Boltzmann model adapted to treat an electron beam generated plasma immersed in a constant magnetic field. The confining effect of the magnetic field is studied theoretically using fluid and kinetic approaches. The fluid approach leads to two regimes of operation: weakly and strongly magnetized. The former is similar to the magnetic field-free case, while in the latter the ambipolar diffusion coefficient and electron density depend quadratically on the magnetic field strength. Finally, a more rigorous kinetic treatment, which accounts for the impact of the magnetic field over the whole distribution of electrons, is used for accurate description of the plasma.

A common molecular template used in the development of D3R-selective antagonists and partial agonists incorporates a butylamide linker between two pharmacophores, a phenylpiperazine moiety and an extended aryl ring system. The series of compounds described herein incorporates a change to that chemical template, replacing the amide functional group in the linker chain with a 1,2,3-triazole group. Although the amide linker in the 4-phenylpiperazine class of D3R ligands has been previously deemed critical for high D3R affinity and selectivity, the 1,2,3-triazole moiety serves as a suitable bioisosteric replacement and maintains desired D3R-binding functionality of the compounds. Additionally, using mouse liver microsomes to evaluate CYP450-mediated phase I metabolism, we determined that novel 1,2,3-triazole-containing compounds modestly improves metabolic stability compared to amide-containing analogues. The 1,2,3-triazole moiety allows for the modular attachment of chemical subunit libraries using copper-catalyzed azide-alkyne cycloaddition click chemistry, increasing the range of chemical entities that can be designed, synthesized, and developed toward D3R-selective therapeutic agents.

In such cases the recovery process will yield artifacts, or in many cases, fail completely. This work represents the first demonstration of a solution to this so-called "off-grid" problem in an experimental, compressively sampled system.

TI SEARCH FOR EARLY GAMMA-RAY PRODUCTION IN SUPERNOVAE LOCATED IN A DENSE CIRCUMSTELLAR MEDIUM WITH THE FERMI LAT SO ASTROPHYSICAL JOURNAL LA English DT Article DE cosmic rays; gamma rays: general; methods: data analysis; supernovae: general ID LARGE-AREA TELESCOPE; SHOCK BREAKOUT; SN 2010JL; CONFIDENCE-INTERVALS; EMISSION; EXPLOSIONS; WIND AB Supernovae (SNe) exploding in a dense circumstellar medium (CSM) are hypothesized to accelerate cosmic rays in collisionless shocks and emit GeV gamma-rays and TeV neutrinos on a timescale of several months. We perform the first systematic search for gamma-ray emission in Fermi Large Area Telescope data in the energy range from 100 MeV to 300 GeV from the ensemble of 147 SNe Type IIn exploding in a dense CSM. We search for a gamma-ray excess at each SNe location in a one-year time window. In order to enhance a possible weak signal, we simultaneously study the closest and optically brightest sources of our sample in a joint-likelihood analysis in three different time windows (1 year, 6 months, and 3 months). For the most promising source of the sample, SN 2010jl (PTF 10aaxf), we repeat the analysis with an extended time window lasting 4.5 years. We do not find a significant excess in gamma-rays for any individual source nor for the combined sources and provide model-independent flux upper limits for both cases. In addition, we derive limits on the gamma-ray luminosity and the ratio of gamma-ray-to-optical luminosity ratio as a function of the index of the proton injection spectrum assuming a generic gamma-ray production model.

JOINT ANALYSIS TECHNIQUE SO ASTROPHYSICAL JOURNAL LA English DT Article DE galaxies: clusters: general; galaxies: clusters: individual (Abell 1835, MACS J0647.7+7015) ID COSMIC DISTANCE SCALE; GREEN-BANK-TELESCOPE; X-RAY MEASUREMENTS; INTRACLUSTER MEDIUM; COMPLETE SAMPLE; POWER SPECTRUM; ABELL-1835; MASS; GAS; SIMULATION AB We present a technique to constrain galaxy cluster pressure profiles by jointly fitting Sunyaev-Zeldovich effect (SZE) data obtained with MUSTANG and Bolocam for the clusters Abell 1835 and MACS0647. Bolocam and MUSTANG probe different angular scales and are thus highly complementary. We find that the addition of the high-resolution MUSTANG data can improve constraints on pressure profile parameters relative to those derived solely from Bolocam. In Abell 1835 and MACS0647, we find gNFW inner slopes of gamma = 0.36(-0.21)(+0.33) and gamma = 0.38(-0.25)(+0.20), respectively, when alpha and beta are constrained to 0.86 and 4.67, respectively. The fitted SZE pressure profiles are in good agreement with X-ray derived pressure profiles. C1 [Romero, Charles E.] Natl Radio Astron Observ, Charlottesville, VA 22903 USA.

TI A HIGHLY ECCENTRIC 3.9 MILLISECOND BINARY PULSAR IN THE GLOBULAR CLUSTER NGC 6652 SO ASTROPHYSICAL JOURNAL LETTERS LA English DT Article DE binaries: close; equation of state; globular clusters: individual (NGC 6652, NGC 6388); gravitation; pulsars: individual (NGC 6652A) ID X-RAY BINARIES; RELATIVISTIC CELESTIAL MECHANICS; BRIGHTNESS PROFILES; MILKY-WAY; PARAMETERS; EMISSION; SYSTEMS; TELESCOPE; NGC-6652; CATALOG AB We present the Robert C. Byrd Green Bank Telescope discovery of the highly eccentric binary millisecond pulsar PSR J1835-3259A in the Fermi Large Area Telescope-detected globular cluster NGC 6652. Timing over one orbit yields the pulse period 3.89 ms, orbital period 9.25 days, eccentricity similar to 0.95, and an unusually high companion mass of 0.74 M-circle dot assuming a 1.4 M-circle dot pulsar. We caution that the lack of data near periastron prevents a precise measurement of the eccentricity, and that further timing is necessary to constrain this and the other orbital parameters. From tidal considerations, we find that the companion must be a compact object. This system likely formed through an exchange encounter in the dense cluster environment. Our initial timing results predict the measurements of at least two post- Keplerian parameters with long-term phase-connected timing: the rate of periastron advance omega similar to 0.degrees 1 yr(-1), requiring 1 year of phase connection; and the Einstein delay gamma(GR) similar to 10 ms, requiring 2-3 years of timing. For an orbital inclination i > 50 degrees, a measurement of sin i is also likely. PSR J1835-3259A thus provides an opportunity to measure the neutron star mass with high precision, to probe the cluster environment, and, depending on the nature of the companion, to investigate the limits of general relativity.

CA STAR Collaboration TI Beam-energy-dependent two-pion interferometry and the freeze-out eccentricity of pions measured in heavy ion collisions at the STAR detector SO PHYSICAL REVIEW C LA English DT Article ID QUARK-GLUON PLASMA; RELATIVISTIC NUCLEAR COLLISIONS; BOSE-EINSTEIN CORRELATIONS; TRANSVERSE-MOMENTUM; COULOMB CORRECTIONS; PB+PB COLLISIONS; PHASE-TRANSITION; CRITICAL-POINT; SPS ENERGIES; QCD AB We present results of analyses of two-pion interferometry in Au + Au collisions at root s(NN) = 7.7, 11.5, 19.6, 27, 39, 62.4, and 200 GeV measured in the STAR detector as part of the BNL Relativistic Heavy Ion Collider Beam Energy Scan program. The extracted correlation lengths (Hanbury-Brown-Twiss radii) are studied as a function of beam energy, azimuthal angle relative to the reaction plane, centrality, and transverse mass (m(T)) of the particles. The azimuthal analysis allows extraction of the eccentricity of the entire fireball at kinetic freeze-out. The energy dependence of this observable is expected to be sensitive to changes in the equation of state. A new global fit method is studied as an alternate method to directly measure the parameters in the azimuthal analysis. The eccentricity shows a monotonic decrease with beam energy that is qualitatively consistent with the trend from all model predictions and quantitatively consistent with a hadronic transport model.

The proposed methodology simultaneously takes into account multi-fidelity in models, such as direct numerical simulations versus empirical formulae, as well as multi-fidelity in the probability space (e.g. sparse grids versus tensor product multi-element probabilistic collocation). We are able to construct response surfaces of complex dynamical systems by blending multiple information sources via auto-regressive stochastic modelling. A computationally efficient machine learning framework is developed based on multi-level recursive co-kriging with sparse precision matrices of Gaussian-Markov random fields. The effectiveness of the new algorithms is demonstrated in numerical examples involving a prototype problem in risk-averse design, regression of random functions, as well as uncertainty quantification in fluid mechanics involving the evolution of a Burgers equation from a random initial state, and random laminar wakes behind circular cylinders.

TI Ultrasensitive Detection of Ricin Toxin in Multiple Sample Matrixes Using Single-Domain Antibodies SO ANALYTICAL CHEMISTRY LA English DT Article ID MOLECULE ARRAYS; ASSAY; PROTEIN; INFECTION; TOXICITY; COMMUNIS; PHAGE AB Ricin is an extremely potent ribosomal inactivating protein listed as a Category B select agent. Although ricin intoxication is not transmittable from person to person, even a single ricin molecule can lead to cell necrosis because it inactivates 1500 ribosomes/min. Since there is currently no vaccine or therapeutic treatment for ricin intoxication, ultrasensitive analytical assays capable of detecting ricin in a variety of matrixes are urgently needed to limit exposure to individuals as well as communities. In this paper, we present the development and application of a single-molecule array (Simoa) for the detection of ricin toxin in human urine and serum. Single-domain antibodies (sdAbs), among the smallest engineered binding fragments, were chemically coupled to the surface of paramagnetic beads for the sensitive detection of ricin toxin. The Simoa was able to detect ricin at levels of 10 fg/mL, 100 fg/mL, and 1 pg/mL, in buffer, urine and serum, respectively, in a fraction of the assay time need using immuno-polymerase chain reaction (IPCR). Using a fully automated state-of-the-art platform, the Simoa HD-1 analyzer, the assay time was reduced to 64 min.

TI Equivalent sources method for supersonic intensity of arbitrarily shaped geometries SO JOURNAL OF SOUND AND VIBRATION LA English DT Article ID FIELD ACOUSTIC HOLOGRAPHY; SURFACE; POWER; FORMULATIONS AB Supersonic acoustic intensity is utilized to locate radiating regions on a complex vibrating structure. The supersonic intensity is obtained by a special process that removes the evanescent waves from the near-field acoustical holography measurement. The altering process is well understood for separable geometries, but unfortunately, there are few results for arbitrarily shaped objects. This work proposes a methodology based on a stable invertible representation of the radiated power operator. The power operator is approximated numerically by the equivalent source formulation and the appropriate complete spectral basis is employed to form the stable invertible operator. The operator is formed with the most efficient radiation modes and these modes are utilized to obtain the supersonic solution for the near-field holographic problem. This concept is tested using numerically generated data in a spherical geometry and the results are validated with the spherical harmonic, supersonic alter. Finally, a vibrating ship-hull structure provides a physical example for application and validation of the proposed methodology in a more complex geometry. Published by Elsevier Ltd.

TI Thin Fresnel zone plate lenses for focusing underwater sound SO APPLIED PHYSICS LETTERS LA English DT Article ID ULTRASONIC-WAVES; AIR; PHASE AB A Fresnel zone plate (FZP) lens of the Soret type creates a focus by constructive interference of waves diffracted through open annular zones in an opaque screen. For underwater sound below MHz frequencies, a large FZP that blocks sound using high-impedance, dense materials would have practical disadvantages. We experimentally and numerically investigate an alternative approach of creating a FZP with thin (0.4 lambda) acoustically opaque zones made of soft silicone rubber foam attached to a thin (0.1 lambda) transparent rubber substrate. An ultra-thin (0.0068 lambda) FZP that achieves higher gain is also proposed and simulated which uses low-volume fraction, bubble-like resonant air ring cavities to construct opaque zones. Laboratory measurements at 200 kHz indicate that the rubber foam can be accurately modeled as a lossy fluid with an acoustic impedance approximately 1/10 that of water. Measured focal gains up to 20 dB agree with theoretical predictions for normal and oblique incidence. The measured focal radius of 0.68 lambda (peak-to-null) agrees with the Rayleigh diffraction limit prediction of 0.61 lambda/NA (NA = 0.88) for a low-aberration lens.

It has not been synthesized through traditional physical vapor deposition (PVD) techniques because of its thermodynamic instability in low oxygen pressures. Epitaxial thin films of Ru doped tetragonal rutile CrO2 were synthesized by a PVD technique. The as-deposited RuxCr1-xO2 was ferrimagnetic with the saturation magnetization moment showing a strong dependence on the Ru concentration. Curie temperature as high as 241K has been obtained for similar to 23 at. % Ru. The Ru substitution increased the electrical conductivity by increasing the minority spin concentration. The spin polarization was found to be as high as 70% for 9 at.% Ru and decreased to similar to 60% with Ru concentrations up to similar to 44 at. %, which is determined by the Fermi velocities of the majority and minority spins. First principle calculations were performed to understand the effect of Ru content on the properties of CrO2. The PVD processes of Ru doped CrO2 could lead to the practical applications of the high spin polarization of CrO2 in spintronic devices. (C) 2015 AIP Publishing LLC. C1 [West, Kevin G.; Dao, Nam N.

TI Integer domination of Cartesian product graphs SO DISCRETE MATHEMATICS LA English DT Article DE Vizing's conjecture; Domination theory; Product graphs ID NUMBER AB Given a graph G, a dominating set D is a set of vertices such that any vertex not in D has at least one neighbor in D. A {k}-dominating multiset D-k is a multiset of vertices such that any vertex in G has at least k vertices from its closed neighborhood in D-k when counted with multiplicity. In this paper, we utilize the approach developed by Clark and Suen (2000) to prove a "Vizing-like" inequality on minimum {k}-dominating multisets of graphs G rectangle H and the Cartesian product graph G rectangle H. Specifically, denoting the size of a minimum {k}-dominating multiset as gamma({k})(G), we demonstrate that gamma({k}) (G)gamma({k})(H) <= 2k gamma({k})(G rectangle H).

Instead, wars in which there is a break in external support are more likely to continue into the next calendar year than even those wars with continued external support.

These new data are ground-based 630 nm Fabry-Perot Interferometer (FPI) measurements in the equatorial and polar regions, as well as cross-track winds from the Gravity Field and Steady State Ocean Circulation Explorer (GOCE) satellite. The GOCE wind observations provide valuable wind data in the twilight regions. The ground-based FPI measurements fill latitudinal data gaps in the prior observational database. Construction of this reference model also provides the opportunity to compare these new measurements. The resulting update (HWM14) provides an improved time-dependent, observationally based, global empirical specification of the upper atmospheric general circulation patterns and migrating tides. In basic agreement with existing accepted theoretical knowledge of the thermosphere general circulation, additional calculations indicate that the empirical wind specifications are self-consistent with climatological ionosphere plasma distribution and electric field patterns.

Objective: To describe a novel protocol for the treatment of acute lateral patellar dislocation that returns patients to play far sooner than traditional treatment protocols. Design: Case series and review of the literature. Setting: Division I NCAA institution. Patients: Two collegiate athletes who sustained first-time acute lateral patellar dislocations. Interventions: Traditional standard of care for acute lateral patellar dislocation after reduction involves 1-7 weeks of immobilization in full extension. Knee stiffness commonly results from this method, and return to full activity typically takes 2-4 months. We used a protocol involving immobilization in maximal flexion for 24 hr, with early aggressive range of motion and quadriceps strengthening in the first week after injury. Main Outcome Measures: Time to return to play. Results: Immediate on-site reduction of the patella followed by 24 hr of immobilization in maximal knee flexion was performed. Following an accelerated rehabilitation regimen, patients were able to return to sport an average of 3 days postinjury. Neither patient has experienced a recurrent dislocation. Conclusions: Our protocol is based on anatomic studies demonstrating reduced tension on the medial patellofemoral ligament, reduced hemarthrosis, and reduced soft tissue swelling in maximal knee flexion. This method apparently bypasses the knee stiffness and deconditioning commonly seen with traditional nonoperative regimens, allowing return to sport weeks or months sooner.

Global sensitivity analysis algorithms enable more complete system characterization for more complex, nondifferentiable models, such as a digital elevation model (DEM). This paper develops the necessary framework for applying global sensitivity analysis methods to geolocation systems and demonstrates the algorithm's enhanced fidelity by applying it to an example angle of arrival and DEM geolocation system. Terrain roughness is found to be a significant parameter solely through interaction effects with other parameters, effects that would have been missed by simpler analyses.

Most published tracking algorithms ignore light-time delays, implying that the time the light hit the target is ascertained from each measurement individually. This paper demonstrates that prediction biases worsen at high bistatic angles and exceed 250 m magnitude in a realistic scenario, indicating that more specialized algorithms should be used in such scenarios.

The probe is a combination of graphite electrodes, filter paper, with ethylene glycol and choline chloride as the solvent/electrolyte. Square wave chromatovoltammograms show the probes have a sensitivity for TNT of 0.75 nA/ng and a limit of detection of 100 ng. In addition, by taking advantage of the inherent paper chromatography step, TNT can be separated in both time and cathodic peak potential from 4-amino-dinitrotolene co-spotted on the probe or in soil samples with the presence of methyl parathion as a possible interferent.

The set-up is composed of environmental baroclinicity defined by a zonally uniform jet in thermal wind balance with a meridional temperature gradient and moisture content defined by relative humidity profiles. Initiation of disturbance growth is achieved by superimposing a weak, surface-based warm-cored cyclonic disturbance to the set-up. The experiments show that the disturbance is able to amplify within such an environment in the absence of an upper-level perturbation, surface fluxes, friction, or radiation. Separation between developing and non-developing disturbances is feasible by considering the baroclinic and diabatic contributions to eddy available potential energy. Developing disturbances show a clear diabatic dominance during the early stage of development, whereas experiments lacking this diabatic boost fail to intensify within a 3-day time window. A comparison with the conceptual framework of the Diabatic Rossby Vortex (DRV) growth mechanism provides insight into the dynamical pathway potentially underlying the enhanced amplification. The emerging disturbance qualitatively resembles the postulated DRV structure, the major difference being a decreased depth in comparison with simulated and observed DRVs in midlatitudes. A suit of sensitivity experiments examines the range of atmospheric conditions in which enhanced amplification by diabatic processes is possible. Threshold values for moisture content and isentropic slopes are identified. C1 [Terpstra, Annick; Spengler, Thomas] Univ Bergen, Inst Geophys, N-5020 Bergen, Norway.

A review of all active duty patients undergoing coronary artery bypass grafting (CABG), mitral valve repair (MVrep), bioprosthetic valve replacement (BIOVALVE), mechanical valve replacement (MECHVALVE), and septal defect closure (ASD/VSD) at Naval Medical Center Portsmouth between January 1, 2004 and December 31, 2011 was used to determine final duty status: Return to Full Duty (RTFD), Medical Board Separation or Planned Retirement/Separation. Complete data on final disposition was available for 99% (75/76) of patients. There were 9 Planned Retirement/Separation patients. There was a 100% rate of RTFD for all MVrep, BIOVALVE, and ASD/VSD patients. Patients undergoing CABG had an 83% (20/23) rate of RTFD. MECHVALVE patients had RTFD in only 23% (5/21) of cases. Patients undergoing MECHVALVE are unlikely to be suitable for continued service after surgery, but most if not all military patients undergoing MVrep, ASD/VSD, or BIOVALVE and the vast majority of CABG patients can expect to return to unrestricted active duty after surgery.

Twenty-nine Naval Special Warfare (NSW) Operators wore an actiwatch for an 8-day/7-night period for objective sleep assessment and completed a nightly sleep log. A total of 170 nights of actigraphically recorded sleep were collected. When comparing objectively versus subjectively recorded sleep parameter data, statistically significant differences were found. Compared with sleep log data, actigraphy data indicate NSW Operators took longer to fall asleep (an average of 25.82 minutes), spent more time awake after sleep onset (an average of 39.55 minutes), and demonstrated poorer sleep efficiency (83.88%) (ps < 0.05). Self-reported sleep quality during the study period was 6.47 (maximum score = 10). No relationships existed between the objectively derived sleep indices and the self-reported measure of sleep quality (rs = -0.29 to 0.09, all ps > 0.05). Strong inter-relationships existed among the subjectively derived sleep indices (e.g., between self-reported sleep quality and sleep efficiency; r = 0.61, p < 0.001). To our knowledge, this is the first study to objectively and subjectively quantify sleep among NSW Operators. These findings suggest sleep maintenance and sleep efficiency are impaired when compared to normative population data.

A model for dengue fever is driven by simulated data from secondary infective populations. Primary infective populations in the driven system synchronize to the correct values from the driver system. Most hospital cases of dengue are secondary infections, so this method provides a way to deduce unobserved primary infection levels. We derive center manifold equations that relate the driven system to the driver system and thus motivate the use of synchronization to predict unobserved primary infectives. Synchronization stability between primary and secondary infections is demonstrated through numerical measurements of conditional Lyapunov exponents and through time series simulations.

TI Simulation of shallow-water jets with a unified element-based continuous/discontinuous Galerkin model with grid flexibility on the sphere SO QUARTERLY JOURNAL OF THE ROYAL METEOROLOGICAL SOCIETY LA English DT Article DE reduced lat-lon grids; icosahedral grid; cubed-sphere; shallow-water equations; spectral element method; discontinuous Galerkin; grid generation on the sphere; transfinite interpolation ID DIFFERENTIAL-EQUATIONS; CUBED-SPHERE; GEOMETRY; DISCRETIZATION; APPROXIMATIONS; DRY AB We test the behaviour of a unified continuous/discontinuous Galerkin (CG/DG) shallow-water model in spherical geometry with curved elements on three different grids of ubiquitous use in atmospheric modelling: (i) the cubed-sphere, (ii) the reduced latitude-longitude, and (iii) the icosahedral grid. Both conforming and non-conforming grids are adopted including static and dynamically adaptive grids for a total of twelve mesh configurations. The behaviour of CG and DG on the different grids are compared for a nonlinear midlatitude perturbed jet and for a linear case that admits an analytic solution. Because the inviscid solution on certain grids shows a high sensitivity to the resolution, the viscous counterpart of the governing equations is also solved and the results compared. The logically unstructured element-based CG/DG model described in this article is flexible with respect to arbitrary grids. However, we were unable to define a best grid configuration that could possibly minimize the error regardless of the characteristic geometry of the flow. This is especially true if the governing equations are not regularized by the addition of a sufficiently large, fully artificial, diffusion mechanism, as will be shown. The main novelty of this study lies in the unified implementation of two element-based Galerkin methods that share the same numerical machinery and do not rely on any specific grid configuration to solve the shallow-water equation on the sphere.

TI Similarity theory based on the Dougherty-Ozmidov length scale SO QUARTERLY JOURNAL OF THE ROYAL METEOROLOGICAL SOCIETY LA English DT Article DE Dougherty-Ozmidov length scale; mixing efficiency; Monin-Obukhov similarity theory; oceanic vertical mixing; stable boundary layer; z-less similarity ID ATMOSPHERIC SURFACE-LAYER; STABLE BOUNDARY-LAYER; TURBULENT KINETIC-ENERGY; FLUX-PROFILE RELATIONSHIPS; DISSIPATION RATE; LOCAL ISOTROPY; TEMPERATURE PROFILES; RICHARDSON-NUMBER; STRATIFIED FLUID; SELF-CORRELATION AB This article describes a local similarity theory for developed turbulence in the stably stratified boundary layer that is based on the Brunt-Vaisala frequency and the dissipation rate of turbulent kinetic energy instead of the turbulent fluxes used in the traditional Monin-Obukhov similarity theory. Based on dimensional analysis (Pi theorem), it is shown that any properly scaled statistics of the small-scale turbulence are universal functions of a stability parameter defined as the ratio of a reference height z and the Dougherty-Ozmidov length scale, which in the limit of z-less stratification is linearly proportional to the Obukhov length scale. Measurements of atmospheric turbulence made at five levels on a 20 m tower over the Arctic pack ice during the Surface Heat Budget of the Arctic Ocean experiment (SHEBA) are used to examine the behaviour of different similarity functions in the stable boundary layer. In the framework of this approach the non-dimensional turbulent viscosity is equal to the gradient Richardson number, whereas the non-dimensional turbulent thermal diffusivity is equal to the flux Richardson number. These results are a consequence of the approximate local balance between production of turbulence by shear in the mean flow and viscous dissipation. The turbulence framework based on the Brunt-Vaisala frequency and the dissipation rate of turbulent kinetic energy may have practical advantages for estimating turbulence when the fluxes are not directly available.

Ko, Hanseok TI Visual Speech Recognition Using Weighted Dynamic Time Warping SO IEICE TRANSACTIONS ON INFORMATION AND SYSTEMS LA English DT Article DE visual speech recognition; lip reading ID CLASSIFICATION AB It is unclear whether Hidden Markov Model (HMM) or Dynamic Time Warping (DTW) mapping is more appropriate for visual speech recognition when only small data samples are available. In this letter, the two approaches are compared in terms of sensitivity to the amount of training samples and computing time with the objective of determining the tipping point. The limited training data problem is addressed by exploiting a straightforward template matching via weighted-DTW. The proposed framework is a refined DTW by adjusting the warping paths with judicially injected weights to ensure a smooth diagonal path for accurate alignment without added computational load. The proposed WDTW is evaluated on three databases (two in the public domain and one developed in-house) for visual recognition performance. Subsequent experiments indicate that the proposed WDTW significantly enhances the recognition rate compared to the DTW and HMM based algorithms, especially under limited data samples.

TI Coronal Pseudo-Streamer and Bipolar Streamer Observed by SOHO/UVCS in March 2008 SO SOLAR PHYSICS LA English DT Article DE Corona; Streamer; Solar wind; MHD model ID WHOLE SUN MONTH; SOLAR-WIND VELOCITY; SLOW WIND; PSEUDOSTREAMERS; MINIMUM; HOLE; SPECTROMETER; DENSITY; LASCO AB The past solar minimum is characterized by several peculiar aspects and by a complex magnetic topology with two different types of coronal streamers: pseudo-streamers and bipolar streamers. Pseudo-streamers or unipolar streamer are coronal structures that separate coronal holes of the same polarity, without a current sheet in the outer corona; unlike bipolar streamers, which separate coronal holes of opposite magnetic polarity. In this study, two examples of these structures have been identified in the period of Carrington rotation 2067 by applying a potential-field source-surface extrapolation of the photospheric field measurements. We present a spectroscopic analysis of a pseudo-streamer and a bipolar streamer observed in the period 12 -aEuro parts per thousand 17 March 2008 at high spectral and spatial resolution by the Ultraviolet Coronagraph Spectrometer (UVCS; Kohl et al., Solar Phys. 162, 313, 1995) onboard the Solar and Heliospheric Observatory (SOHO). The solar wind plasma parameters, such as kinetic temperature, electron density, and outflow velocity, were inferred in the extended corona (from 1.7 to ) by analyzing the O vi doublet and H i Ly line spectra. The coronal magnetic topology was taken into account and was extrapolated with a 3D magneto-hydrodynamic model of the global corona. The results of the analysis show some peculiarities of the pseudo-streamer physical parameters in comparison with those obtained for bipolar streamers: in particular, we have found a higher kinetic temperature and higher outflow velocities of O vi ions and lower electron density values. In conclusion, we point out that pseudo-streamers produce a hybrid type of outflow that is intermediate between the slow and fast solar winds. These outflows are a possible source of slow/fast wind in a non-dipolar solar magnetic field configuration. C1 [Abbo, L.] Osservatorio Astrofis Torino, INAF, I-10025 Pino Torinese, Italy.

We examine the tunneling behavior through measuring the IV curves and zero bias resistance. We also fabricate hydrogenated graphene/graphene nonlocal spin valves and measure the spin lifetimes using the Hanle effect, with spintronic nonlocal spin valve operation demonstrated up to room temperature. We show that while hydrogenated graphene indeed allows for spin transport in graphene and has many advantages over oxide tunnel barriers, it does not perform as well as similar fluorinated graphene/graphene devices, possibly due to the presence of magnetic moments in the hydrogenated graphene that act as spin scatterers.

We have previously shown that intensely photoluminescent 9-nm diameter quantum dots (QDs) with a CdSe core, a ZnS shell, and a negatively charged compact molecular ligand coating (CL4) selectively target neurons rather than glia. We now provide an explanation for this selective neuronal delivery. In this study, we compared three zwitterionic QD coatings differing only in their regions of positive or negative charge, as well as a positively charged (NH2) polyethylene glycol (PEG) coat, for their ability to deliver the cell-membrane-penetrating chaperone lipopeptide JB577 (WG(Palmitoyl) VKIKKP(9)G(2)H(6)) to individual cells in neonatal rat hippocampal slices. We confirm both that preferential uptake in neurons, and the lack of uptake in glia, is strongly associated with having a region of greater negative charge on the QD coating. In addition, the role of negatively charged chondroitin sulfate of the extracellular matrix (ECM) in restricting uptake was further suggested by digesting neonatal rat hippocampal slices with chondroitinase ABC and showing increased uptake of QDs by oligodendrocytes. Treatment still did not affect uptake in astrocytes or microglia. Finally, the future potential of using QDs as vehicles for trafficking proteins into cells continues to show promise, as we show that by administering a histidine-tagged green fluorescent protein (eGFP-His(6)) to hippocampal slices, we can observe neuronal uptake of GFP.

Research design: Participants were male, US military personnel treated in Afghanistan within 4 days following an IED-related mTBI event (n=239). Methods and procedures: Demographics, diagnosis of ASR, injury history and self-reported mTBIs, blast exposures and psychological health histories were recorded. Main outcomes and results: In total, 12.5% of patients met ASR criteria. Patients with ASR were significantly younger and junior in rank (p<0.05). Patients with ASR were more likely to experience the IED-blast while dismounted, report a loss of consciousness (LOC) and higher pain levels (p<0.05). Adjusting for age and rank, multivariate logistic regression showed an association between mTBI history and ASR (AOR = 1.405; 95% CI = 1.105-1.786, p<0.01). Adjusting for mechanism of injury (dismounted vs. mounted), LOC and pain, multivariate logistic regression showed an association between mTBI history and ASR (AOR = 1.453; 95% CI = 1.132-1.864, p<0.01). Prior blast exposure and past psychological health issues were not associated with ASR. Conclusions: A history of multiple mTBIs is associated with increased risk of ASR. Future research is warranted. C1 [Norris, Jacob N.] Naval Med Res Ctr, Neurotrauma Dept, Silver Spring, MD 20910 USA. [Smith, Scottie] Branch Hlth Clin Kings Bay, Kings Bay, GA USA.

While these distortions are usually deleterious to propagation, beams reflected in a turbulent medium can undergo a local recovery of spatial coherence and intensity enhancement referred to as enhanced backscatter (EBS). Here we validate the commonly used phase screen simulation with experimental results obtained from lab-scale experiments. We also verify theoretical predictions of the dependence of the turbulence strength on EBS. Finally, we present a novel algorithm called the "tilt-shift method" which allows detection of EBS in frozen turbulence, reducing the time required to detect the EBS signal.

Gammon, Daniel TI Spin-cavity interactions between a quantum dot molecule and a photonic crystal cavity SO NATURE COMMUNICATIONS LA English DT Article ID NANOCAVITY; QUBIT AB The integration of InAs/GaAs quantum dots into nanophotonic cavities has led to impressive demonstrations of cavity quantum electrodynamics. However, these demonstrations are primarily based on two-level excitonic systems. Efforts to couple long-lived quantum dot electron spin states with a cavity are only now succeeding. Here we report a two-spin-cavity system, achieved by embedding an InAs quantum dot molecule within a photonic crystal cavity. With this system we obtain a spin singlet-triplet Lambda-system where the ground-state spin splitting exceeds the cavity linewidth by an order of magnitude. This allows us to observe cavity-stimulated Raman emission that is highly spin-selective. Moreover, we demonstrate the first cases of cavity-enhanced optical nonlinearities in a solid-state Lambda-system. This provides an all-optical, local method to control the spin exchange splitting. Incorporation of a highly engineerable quantum dot molecule into the photonic crystal architecture advances prospects for a quantum network.

TI The Flaring of Intellectual Outliers: An Organizational Interpretation of the Generation of Novelty in the RAND Corporation SO ORGANIZATION SCIENCE LA English DT Article DE organizational evolution and change; organization and management theory; archival research; organizational processes; organization and management theory; deviance; innovation ID UNITED-STATES; INNOVATION; INSTITUTIONS; PERSPECTIVE; KNOWLEDGE; SYSTEMS AB Much of intellectual history is punctuated by the flaring of intellectual outliers, small groups of thinkers who briefly, but decisively, influence the development of ideas, technologies, policies, or worldviews. To understand the flaring of intellectual outliers, we use archival and interview data from the RAND Corporation after the Second World War. We focus on five factors important to the RAND experience: (1) a belief in fundamental research as a source of practical ideas, (2) a culture of optimistic urgency, (3) the solicitation of renegade ambition, (4) the recruitment of intellectual cronies, and (5) the facilitation of the combinatorics of variety. To understand the subsequent decline of intellectual outliers at RAND, we note that success yields a sense of competence, endurance in a competitive world, and the opportunity and inclination to grow. Self-confidence, endurance, and growth produce numerous positive consequences for an organization; but for the most part, they undermine variety. Outliers and the conditions that produce them are not favored by their environments. Engineering solutions to this problem involve extending time and space horizons, providing false information about the likelihoods of positive returns from exploration, buffering exploratory activities from the pressures of efficiency, and protecting exploration from analysis by connecting it to dictates of identities.

TI Simultaneous Bilateral Anterior Approach Total Hip Arthroplasty SO ORTHOPEDICS LA English DT Article ID ONE-STAGE; 2-STAGE PROCEDURES; KNEE ARTHROPLASTY; SINGLE PROCEDURE; REPLACEMENT; OSTEOARTHRITIS; COMPLICATIONS; EFFICACY; SAFETY AB Simultaneous bilateral total hip arthroplasty (THA) has been performed successfully, with good outcomes and low complication rates reported. Most published studies on the topic used anterolateral or posterior surgical approaches. The anterior approach is performed under live fluoroscopy with the patient supine, obviating the need for patient repositioning during bilateral surgery. The authors report their experience with simultaneous bilateral anterior approach total hip arthroplasty. The authors retrospectively reviewed data for 75 patients (150 hips). Mean follow-up was 26 months (range, 5-60 months). Mean patient age was 59 years and the majority were American Society of Anesthesiology class 2 (range, 1-3). Mean total surgical time was 144 minutes (72 minutes per hip). Mean blood loss was 565 mL. Mean hospital length of stay was 2.75 days (range, 1-4 days). Ninety-six percent of patients were able to ambulate on postoperative day 1. Sixty-eight percent of patients were discharged to home. Mean Harris Hip Score improved from 50 to 97. All patients noted a return to preoperative level of activity or higher. Complications included 1 atraumatic minimally displaced trochanteric fracture occurring 2 weeks postoperatively, 1 pulmonary embolism on postoperative day 3 treated without sequelae, 1 episode of postoperative atrial fibrillation, and 4 minor local wound complications. No readmission, infection, nerve palsy, dislocation, reoperation, or death occurred. Anterior approach THA has the advantage of a single supine position for bilateral simultaneous surgery and the current study supports its use in appropriate patients.

TI Electromagnetic drift waves dispersion for arbitrarily collisional plasmas SO PHYSICS OF PLASMAS LA English DT Article ID SCRAPE-OFF-LAYER; DIII-D; TURBULENCE; TRANSPORT; EDGE; TOKAMAK; BLOB AB The impacts of the electromagnetic effects on resistive and collisionless drift waves are studied. A local linear analysis on an electromagnetic drift-kinetic equation with Bhatnagar-Gross-Krook-like collision operator demonstrates that the model is valid for describing linear growth rates of drift wave instabilities in a wide range of plasma parameters showing convergence to reference models for limiting cases. The wave-particle interactions drive collisionless drift-Alfven wave instability in low collisionality and high beta plasma regime. The Landau resonance effects not only excite collisionless drift wave modes but also suppress high frequency electron inertia modes observed from an electromagnetic fluid model in collisionless and low beta regime. Considering ion temperature effects, it is found that the impact of finite Larmor radius effects significantly reduces the growth rate of the drift-Alfven wave instability with synergistic effects of high beta stabilization and Landau resonance.

TI GLOBAL STRUCTURE OF ISOTHERMAL DIFFUSE X-RAY EMISSION ALONG THE FERMI BUBBLES SO ASTROPHYSICAL JOURNAL LA English DT Article DE Galaxy: center; Galaxy: halo; X-rays: ISM ID GALACTIC-CENTER; HOT GAS; HALO; TELESCOPE; SPECTRUM; SUZAKU; RADIO; WIND; NUCLEUS; MISSION AB In our previous works, we found absorbed thermal X-ray plasma with kT similar or equal to 0.3 keV observed ubiquitously near the edges of the Fermi bubbles and interpreted this emission as weakly shock-heated Galactic halo gas. Here we present a systematic and uniform analysis of archival Suzaku (29 pointings; 6 newly presented) and Swift (68 pointings; 49 newly presented) data within Galactic longitudes vertical bar l vertical bar < 20 degrees and latitude 5 degrees less than or similar to vertical bar b vertical bar < 60 degrees, covering the whole extent of the Fermi bubbles. We show that the plasma temperature is constant at kT similar or equal to 0.30 +/- 0.07 keV, while the emission measure (EM) varies by an order of magnitude, increasing toward the Galactic center (i.e., low vertical bar b vertical bar) with enhancements at the North Polar Spur (NPS), SE-claw, and NW-clump features. Moreover, the EM distribution of kT similar or equal to 0.30 keV plasma is highly asymmetric in the northern and southern bubbles. Although the association of the X-ray emission with the bubbles is not conclusive, we compare the observed EM properties with simple models assuming (i) a filled halo without bubbles, whose gas density follows a hydrostatic isothermal model (King profile), and (ii) a bubble-in-halo in which two identical bubbles expand into the halo, forming thick shells of swept halo gas. We argue that the EM profile in the north (b > 0 degrees) favors (ii), whereas that of the south (b < 0 degrees) is rather close to (i), but a weak excess signature is clearly detected also in the south like NPS (South Polar Spur). Such an asymmetry, if due to the bubbles, cannot be fully understood only by the inclination of bubbles' axis against the Galactic disk normal, thus suggesting asymmetric outflow due to different environmental/initial conditions.

We obtained four epochs of photometry at 3.6 and 4.5 mu m covering the bar of the LMC and the central region of the SMC in order to probe the variability of extremely red sources missed by variability surveys conducted at shorter wavelengths, and to provide additional epochs of observation for known variables. Our six total epochs of observations allow us to probe infrared (IR) variability on 15 different timescales ranging from similar to 20 days to similar to 5 yr. Out of a full catalog of 1 717 554 (LMC) and 457 760 (SMC) objects, we find 10 (LMC) and 6 (SMC) large amplitude Asymptotic Giant Branch (AGB) variables without optically measured variability owing to circumstellar dust obscuration. The catalog also contains multiple observations of known AGB variables, type I and II Cepheids, eclipsing variables, R CrB stars, and young stellar objects, which will be discussed in following papers. Here we present IR Period-Luminosity (PL) relations for classical Cepheids in the Magellanic Clouds, as well as improved PL relationships for AGB stars pulsating in the fundamental mode using mean magnitudes constructed from six epochs of observations.

In this paper, we conduct a careful analysis of the collective dynamics of a swarm of self-propelled heterogeneous, delay-coupled agents. We show the emergence of collective motion patterns and segregation of populations of agents with different dynamic properties; both of these behaviors (pattern formation and segregation) emerge naturally in our model, which is based on self-propulsion and attractive pair-wise interactions between agents. We derive the bifurcation structure for emergence of different swarming behaviors in the mean field as a function of physical parameters and verify these results through simulation.

TI Cooperative Path Following of Multiple Multirotors Over Time-Varying Networks SO IEEE TRANSACTIONS ON AUTOMATION SCIENCE AND ENGINEERING LA English DT Article DE Consensus algorithms; networked systems; time-coordinated path following ID UNMANNED AERIAL VEHICLES; AUTONOMOUS VEHICLES; SWARM AGGREGATIONS; COORDINATION; SYSTEMS; TRACKING; ROBOTS AB This paper addresses the problem of time-coordination of a team of cooperating multirotor unmanned aerial vehicles that exchange information over a supporting time-varying network. A distributed control law is developed to ensure that the vehicles meet the desired temporal assignments of the mission, while flying along predefined collision-free paths, even in the presence of faulty communication networks, temporary link losses, and switching topologies. In this paper, the coordination task is solved by reaching consensus on a suitably defined coordination state. Conditions are derived under which the coordination errors converge to a neighborhood of zero. Simulation and flight test results are presented to validate the theoretical findings. Note to Practitioners-This paper presents an approach which enables a fleet of multirotor UAVs to follow a set of desired trajectories and coordinate along them, thus satisfying specific spatial and temporal assignments. The proposed solution can be employed in applications in which multiple vehicles are tasked to execute cooperative, collision-free maneuvers, and accomplish a common goal in a safely manner. An example is sequential monitoring, in which the UAVs have to visit and monitor a set of points of interest, while maintaining a desired temporal separation between each other. In this paper, we also simulate a scenario in which the vehicles, positioned in a square room, are required to exchange position with each other. It is shown that the proposed control algorithm not only ensures that the UAVs arrive at the final destinations at the same time, but also guarantees safety, i.e., the vehicles avoid collision with each other at all times.

TI Reactive Motion Planning for Unmanned Aerial Surveillance of Risk-Sensitive Areas SO IEEE TRANSACTIONS ON AUTOMATION SCIENCE AND ENGINEERING LA English DT Article DE Motion planning; risk-sensitive surveillance; unmanned aerial vehicles ID PATH; ALGORITHM AB This paper proposes a reactive motion-planning approach for persistent surveillance of risk-sensitive areas by a team of unmanned aerial vehicles (UAVs). The planner, termed PARCov (Planner for Autonomous Risk-sensitive Coverage), seeks to: i) maximize the area covered by sensors mounted on each UAV; ii) provide persistent surveillance; iii) maintain high sensor data quality; and iv) reduce detection risk. To achieve the stated objectives, PARCov combines into a cost function the detection risk with an uncertainty measure designed to keep track of the regions that have been surveyed and the times they were last surveyed. PARCov reduces the uncertainty and detection risk by moving each quadcopter toward a low-cost region in its vicinity. By reducing the uncertainty, PARCov is able to increase the coverage and provide persistent surveillance. Moreover, a nonlinear optimization formulation is used to determine the optimal altitude for flying each quadcopter in order to maximize the sensor data quality while minimizing risk. The efficiency and scalability of PARCov is demonstrated in simulation using different risk models and an increasing number of UAVs to conduct risk-sensitive surveillance. Evidence of successful physical deployment is provided by experiments with AscTec Pelican quadcopters. Note to Practitioners-This paper was motivated by the viability of UAVs to enhance automation in environmental monitoring, search-and-rescue missions, package delivery, and many other applications. As UAVs become an economically feasible option for deployment, it becomes important to enhance their autonomy so as to increase productivity. In this paper, we develop an approach that uses simple interactions among UAVs to promote maximizing the area coverage while maintaining high sensor data quality and reducing the detection risk. The approach provides scalability, making it easy for UAVs to leave and join the mission as needed. Experimental results in simulation and with real quadcopters provide promising results. In future research, we would like to test and enhance the approach so that it can be used in various applications extending beyond laboratory testings.

Dry in-situ plasma treatments are shown to reduce the estimated density of interface states by over two orders of magnitude compared to a standard wet HCl-treatment, without increasing gate leakage. The chemical compositions of the natively oxidized and treated GaSb surfaces are analyzed via x-ray photoemission spectroscopy (XPS). XPS spectra indicate that the native GaSb oxide is segregated, with Sb-oxide compounds localized at the air interface. Effective H-2/Ar-plasma treatments act to remove the Sb-oxide, resulting in a surface Ga-oxide layer enriched in Ga2O3.

TI Hot photocarrier dynamics in organic solar cells SO NATURE COMMUNICATIONS LA English DT Article ID CONVERSION EFFICIENCY; ENERGY; SEMICONDUCTORS; SEPARATION; MOBILITY AB Photocurrent in an organic solar cell is generated by a charge transfer reaction between electron donors and acceptors. Charge transfer is expected to proceed from thermalized states, but this picture has been challenged by recent studies that have investigated the role of hot excitons. Here we show a direct link between excess excitation energy and photocarrier mobility. Charge transfer from excited donor molecules generates hot photocarriers with excess energy coming from the offset between the lowest unoccupied molecular orbital of the donor and that of the acceptor. Hot photocarriers manifest themselves through a short-lived spike in terahertz photoconductivity that decays on a picosecond timescale as carriers thermalize. Different dynamics are observed when exciting the acceptor at its absorption edge to a thermalized state.

TI The Role of Magnetic Resonance Cholangiopancreatography in the Diagnosis of Choledocholithiasis: Do Benefits Outweigh the Costs? SO AMERICAN SURGEON LA English DT Article AB Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard in evaluation of the biliary tree for choledocholithiasis. Formal indications for magnetic resonance cholangiopancreatography (MRCP) in suspected choledocholithiasis are lacking. Our objective was to determine if MRCP affects management of patients who otherwise would undergo ERCP. A review was conducted of all MRCPs and ERCPs at our institution from 2008 to 2012 with suspected choledocholithiasis. Patients who underwent MRCP and ERCP were compared with those who underwent ERCP alone. Demographic data were collected and notation of whether a post-MRCP ERCP occurred was the primary variable. MRCP was performed in 107 patients for choledocholithiasis. Eighty-eight patients were negative for choledocholithiasis (82%) and 76 were discharged without ERCP (71%). Thirty-one patients received a diagnosis of choledocholithiasis and were referred for ERCP. Of the 19 patients with MRCP-diagnosed common bile duct stones, 95 per cent were confirmed by ERCP (odds ratio 18.0, P < 0.05; agreement 77%, sensitivity 0.76, specificity 0.86, positive predictive value 0.95, negative predictive value 0.50). Length of stay was similar for all groups. A total of 131 patients underwent ERCP without a preprocedural MRCP. Choledocholithiasis was found in 116 patients (92%), whereas 12 patients (9%) had no common bile duct stones and three had an alternate diagnosis. In conclusion, MRCP significantly affected the management of patients who would have undergone ERCP. MRCP did not increase length of stay and contributed to the 95 per cent positivity rate of subsequent ERCPs. These data illustrate the utility of MRCP in suspected choledocholithiasis patients at a low cost with regard to risk and time.

Internet technologies are changing the way individuals form and interact with social contacts and access social support. These technologies have the potential to offer expatriates new sources and means for accessing social support. We investigated the role of blogging technology in expatriates' adjustment to foreign environments through a qualitative analysis of a set of blogs written by foreign individuals living in Canada between 2005 and 2012. We found that the blogging system, which is comprised of the blogging technology, bloggers, discussants, and co-created digital discourse, generated online adjustment support resources which were accessed by expatriates. Online adjustment support resources are social support resources, created and residing online, which may help expatriates deal with their experiences of uncertainty, ambiguity and anxiety and include information, interpretation schemas, and comfort.

Erick TI Adjoint-Free Variational Data Assimilation into a Regional Wave Model SO JOURNAL OF ATMOSPHERIC AND OCEANIC TECHNOLOGY LA English DT Article ID HEIGHT DATA; OCEAN; WAM; SUBSPACE; SPECTRA; SYSTEM; FILTER; RADAR; SEA AB A variational data assimilation algorithm is developed for the ocean wave prediction model [Wave Model (WAM)]. The algorithm employs the adjoint-free technique and was tested in a series of data assimilation experiments with synthetic observations in the Chukchi Sea region from various platforms. The types of considered observations are directional spectra estimated from point measurements by stationary buoys, significant wave height (SWH) observations by coastal high-frequency radars (HFRs) within a geographic sector, and SWH from satellite altimeter along a geographic track. Numerical experiments demonstrate computational feasibility and robustness of the adjoint-free variational algorithm with the regional configuration of WAM. The largest improvement of the model forecast skill is provided by assimilating HFR data (the most numerous among the considered types). Assimilating observations of the wave spectrum from a moored platform provides only moderate improvement of the skill, which disappears after 3 h of running WAM in the forecast mode, whereas skill improvement provided by HFRs is shown to persist up to 9 h. Space-borne observations, being the least numerous, do not have a significant impact on the forecast skill but appear to have a noticeable effect when assimilated in combination with other types of data. In particular, when spectral data from a single mooring are used, the satellite data are found to be the most beneficial as a supplemental data type, suggesting the importance of spatial coverage of the domain by observations.

Millions of soldiers around the world represent one of the most vulnerable populations regarding exposure to human immunodeficiency virus (HIV) infection. The programs for HIV prevention remain the most viable approach to reducing the spread of HIV infection. Very few studies have tested the effectiveness of HIV preventive interventions undertaken in military population. The aim of this study was to determine the effectiveness of educational film to transfer knowledge about HIV infection to soldiers. Methods. We performed a quasi-experimental study among 102 soldiers of the Serbian Armed Forces. The experimental intervention consisted of the HIV knowledge prequestionnaire, watching a film on HIV knowledge, then the post-HIV knowledge questionnaire. The results of pre-and post-HIV knowledge questionnaires were compared. Results. There were 23 questions in the test. The average total score on the questionnaire before watching the film was 18.23 and after watching it was 20.14, which was statistically significant difference (p < 0.001). Conclusions. The results of the study show that viewing a film on HIV infection is an effective method of transferring knowledge about HIV to the Serbian military population.

The technique is based on the assumption of statistical independence of the PEs and drifter accelerations. The method provides a realistic approximation to the probability density function of the accelerations while keeping the difference between the filtered and observed trajectories within the error bars of the positioning noise. Performance of the method is demonstrated in application to real data acquired during the Grand Lagrangian Deployment (GLAD) experiment in the Northern Gulf of Mexico in 2012.

The NCEP analyzed fields during this period are separated into a slowly varying background-flow component, a 10-60-day low-frequency component representing the monsoon gyre, and a 10-day high-pass-filtered component representing Megi and other synoptic-scale motion. It appears that the low-frequency (10-60 day) monsoon gyre interacted with Megi and affected its track. To investigate the effect of the low-frequency mode on Megi, numerical experiments were designed. In the control experiment, the total fields of the analysis are retained in the initial and boundary conditions, and the model is able to simulate Megi's sharp northward turn. In the second experiment, the 10-60-day monsoon gyre mode is removed from the initial and lateral boundary fields, and Megi moves westward and slightly northwestward without turning north. Tracks of the relative positions between the Megi and the monsoon gyre centers suggest that a Fujiwhara effect may exist between the monsoon gyre and Megi. The northward turning of both Megi and the monsoon gyre occurred when the two centers were close to each other and the beta drift was enhanced. A vorticity budget analysis was conducted. It is noted that the Megi moves toward the maximum wavenumber-1 vorticity tendency. The sharp change of the maximum vorticity tendency direction before and after the track turning point is primarily attributed to the change of the horizontal vorticity advection. A further diagnosis shows that the steering of the vertically integrated low-frequency flow is crucial for the change of the horizontal advection tendency.

TI Risk of Anterior Cruciate Ligament Injury in Athletes on Synthetic Playing Surfaces: A Systematic Review SO AMERICAN JOURNAL OF SPORTS MEDICINE LA English DT Article DE anterior cruciate ligament injury; injury risk; playing surfaces; soccer; football ID NATIONAL FOOTBALL LEAGUE; HIGH-SCHOOL FOOTBALL; GENERATION ARTIFICIAL TURF; NATURAL GRASS; RECONSTRUCTION SURGERY; ORTHOPEDIC-SURGEONS; KNEE INJURIES; PLAYERS; FIELDTURF; SEVERITY AB Background: The effect of synthetic playing surfaces on the risk of injury in athletes is frequently debated in the orthopaedic literature. Biomechanical studies have identified increased frictional force at the shoe-surface interface, theoretically increasing the risk of injury relative to natural grass. This increase in frictional force is potentially relevant for the risk of anterior cruciate ligament (ACL) rupture, where noncontact mechanisms are frequent. However, clinical studies examining this issue have shown mixed results. Hypothesis/Purpose: The purpose of this study was to systematically review the available literature on risk of ACL rupture on natural grass versus artificial turf. We hypothesized that the risk of ACL rupture on synthetic playing surfaces would not be higher than that of natural grass playing surfaces. Study Design: Systematic review. Methods: A systematic keyword search was performed of OVID, EMBASE, the Cochrane Library of Systematic Reviews, and the PROSPERO International Prospective Register of Systematic Reviews. Candidate articles were included if they reported the risk ratio of ACL rupture on natural grass versus synthetic playing surfaces, were of level 3 evidence or better, and included only ACL injuries sustained during organized athletic events. Exclusion criteria included a study with non-field-related sports and the use of historical cohorts for calculating risk ratios. Results: A total of 10 studies with 963 ACL injuries met criteria for inclusion, all of which reported on soccer and football cohorts. Among these, 4 studies (753 ACL injuries) found an increased risk of ACL injury on artificial playing surfaces. All 4 of these articles were conducted using American football cohorts, and they included both earlier-generation surfaces (AstroTurf) and modern, 3rd-generation surfaces. Only 1 study in football players found a reduced risk of ACL injury on synthetic playing surfaces. No soccer cohort found an increased risk of ACL injury on synthetic surfaces. Conclusion: High-quality studies support an increased rate of ACL injury on synthetic playing surfaces in football, but there is no apparent increased risk in soccer. Further study is needed to clarify the reason for this apparent discrepancy.

Despite the risk these and similar tree hole-inhabiting mosquitoes present to global public health, surprisingly few studies have been conducted to determine an efficient method of applying larvicides specifically to tree holes. The Stihl SR 450, a backpack sprayer commonly utilized during military and civilian vector control operations, may be suitable for controlling larval tree-hole mosquitoes, as it is capable of delivering broadcast applications of granular and liquid dispersible formulations of Bacillus thuringiensis var. israelensis (Bti) to a large area relatively quickly. We compared the application effectiveness of two granular (AllPro Sustain MGB and VectoBac GR) and two liquid (Aquabac XT and VectoBac WDG) formulations of Bti in containers placed on bare ground, placed beneath vegetative cover, and hung 1.5 or 3m above the ground to simulate tree holes. Aedes aegypti (L.) larval mortality and Bti droplet and granule density data (when appropriate) were recorded for each formulation. Overall, granular formulations of Bti resulted in higher mortality rates in the simulated tree-hole habitats, whereas applications of granular and liquid formulations resulted in similar levels of larval mortality in containers placed on the ground in the open and beneath vegetation.

During The Observing System Research and Predictability Experiment (THORPEX) Pacific Asian Regional Campaign (T-PARC)/Tropical Cyclone Structure-2008 (TCS-08) field experiment, over 50 tropical cloud clusters were monitored for development, but only 4 developed into a tropical cyclone. One nondeveloping tropical disturbance (TCS025) was closely observed for potential formation during five aircraft research missions, which provided an unprecedented set of observations pertaining to the large-scale and convective environments of a nondeveloping system. The TCS025 disturbance was comprised of episodic convection that occurred in relation to the diurnal cycle along the eastern extent of a broad low-level trough. The upper-level environment was dominated by two cyclonic cells in the tropical upper-tropospheric trough (TUTT) north of the low-level trough in which the TCS025 circulation was embedded. An in-depth examination of in situ observations revealed that the nondeveloping circulation was asymmetric and vertically misaligned, which led to larger system-relative flow on the mesoscale. Persistent environmental vertical wind shear and horizontal shearing deformation near the circulation kept the system from becoming better organized and appears to have allowed low equivalent potential temperature ( [GRAPHICS] ) air originating from one of the TUTT cells to the north (upshear) to impact the thermodynamic environment of TCS025. This in turn weakened subsequent convection that might otherwise have improved alignment and contributed to the transition of TCS025 to a tropical cyclone.

The modification of psychological tasks gives insight into understanding how to effectively train military decision makers and how experienced decision makers arrive at optimal or near optimal decisions. We developed a task modeled after the Iowa Gambling Task (IGT) to measure military decision making performance. This new task focuses on high stakes and uncertain environments particular to military decision making conditions. Thirty-four U.S. military officers from all branches of service completed the tasks yielding decision data for validation. The new task retains essential characteristics of the foundational task and gives insight into reinforcement learning of military decision makers. Results indicate that the additional metric of regret defines higher performance at a trial-by-trial level, and clustering by multiple metrics defines high performance groups.

Investigating the Causes of the Earnings Penalty of Being a Tied-migrant Military Spouse SO ARMED FORCES & SOCIETY LA English DT Article DE earnings penalty; tied-migrant spouse; decomposition ID FAMILY MIGRATION; EMPLOYMENT; WIVES; WOMEN; ECONOMICS; HUSBANDS; MARRIAGE; WORK AB Prior empirical research on the earnings penalty of being a tied-migrant has focused primarily on the working wives of servicemen. Over the last couple of decades the increased number of women in the armed forces makes it feasible to study the earnings of another group of tied-migrants, the husbands of servicewomen. Using data from the 2000 U.S. Census, Sample Edited Detail File (SEDF), we show that there is a consistently lower age-earnings pattern for military husbands as well as wives. These annual earnings patterns capture the essence of, but do not provide an explanation for, the observed annual earnings differences. These differences are evaluated using multivariate analysis accounting for sample selectivity. Moreover, decomposition analysis strongly suggests that demand-side factors account for a greater portion of the differences in annual earnings than has been previously acknowledged and, therefore, that retention might respond favorably to job matching assistance and/or employer hiring incentives offered military spouses.

An optimal PMU placement method for power system dynamic state estimation is further formulated as an optimization problem which maximizes the determinant of the empirical observability Gramian and is efficiently solved by the NOMAD solver, which implements the Mesh Adaptive Direct Search algorithm. The implementation, validation, and the robustness to load fluctuations and contingencies of the proposed method are carefully discussed. The proposed method is tested on WSCC 3-machine 9-bus system and NPCC 48-machine 140-bus system by performing dynamic state estimation with square-root unscented Kalman filter. The simulation results show that the determined optimal PMU placements by the proposed method can guarantee good observability of the system states, which further leads to smaller estimation errors and larger number of convergent states for dynamic state estimation compared with random PMU placements. Under optimal PMU placements an obvious observability transition can be observed. The proposed method is also validated to be very robust to both load fluctuations and contingencies.

Using the properties of Riemann-Stieltjes sums, a minimum principle is generated from the limit of a semidiscretization. The optimal control minimizes a Riemann-Stieltjes integral of the Pontryagin Hamiltonian. The challenges associated with addressing the noncommutative operations of integration and minimization are addressed via cubature techniques leading to the concept of hyper-pseudospectral points. These ideas are then applied to address the practical uncertainties in control moment gyroscopes that drive an agile spacecraft. Ground test results conducted at Honeywell demonstrate the new principles. The Riemann-Stieltjes optimal control problem is a generalization of the unscented optimal control problem. It can be connected to many independently developed ideas across several disciplines: search theory, viability theory, quantum control and many other applications involving tychastic differential equations.

TI Flame index and its statistical properties measured to understand partially premixed turbulent combustion SO COMBUSTION AND FLAME LA English DT Article DE Flame index; Partially premixed flames; PLIF; Turbulent flames ID LASER-INDUCED FLUORESCENCE; TURBINE MODEL COMBUSTOR; LARGE-EDDY SIMULATION; NUMERICAL-SIMULATION; EDGE-DETECTION; SWIRL FLAMES; TEMPERATURE; ACETONE; FLOW; JET AB This work addresses some fundamental questions in the area of partially premixed combustion what parameters control the fraction of flamelets that are premixed (versus non-premixed), and what are the locations of high probability of premixed (versus non-premixed) combustion? To answer these questions there is a need to measure the flame index (xi) and its statistical properties, and this information previously has not been available. Flame index is +1 where a premixed flamelet exists and is -1 at the location of a non-premixed flamelet A new method to measure flame index was developed that adds NO2 to the air; acetone is used as one component of the fuel. Laser-induced fluorescence images indicate the locations of flamelets and whether the gradients of the fuel and O-2 are in the same direction or not. Flame index was measured in a gas turbine model combustor that was designed at DLR that is a good example of partially premixed combustion. Measurements show how the mean flame index varies in space; near the fuel injector the combustion is 50% non-premixed and 50% premixed while downstream the flamelets are mostly premixed. This trend is consistent with two numerical simulations of swirl flames; however for simple lifted jet flames the premixed flamelets do not extend so far downstream. It was found that one parameter that controls the fraction of flamelets that are premixed is the ratio of the fuel injection velocity to the air velocity. Increasing this ratio increases the fraction of flamelets that are premixed because it increases the distance that the fuel stream penetrates into the more intense mixing region. Good signal-to-noise ratios of 24 (for acetone) and 13 (for NO2) were achieved and an uncertainty analysis is presented that is based on calibration experiments. (C) 2015 The Combustion Institute.

Due to the challenges arising from mesh quality and large disparity in time-scales, coupled morpho- and hydro-dynamics simulations of bed forms has, for the most part, been restricted to sand wave amplitudes of few centimeters. In this work, we overcome such difficulties by employing the immersed boundary approach and a dual time-stepping technique of the VSL3D model [63]. The VSL3D employs the curvilinear immersed boundary (CURVIB) method along with a suspended sediment load module and is capable of simulating turbulent stratified flows coupled with bed morphodynamic evolution in realistic riverine environments with arbitrarily complex hydraulic structures. Turbulence is handled either via large-eddy simulation (LES) with the dynamic Smagorinski subgrid scale model or unsteady Reynolds-averaged Navier Stokes (URANS) equations closed with the k - omega turbulence model. Simulations in the intermediate-scale OSL channel, in which we also collected experimental morphodynamic data, show that LES can capture the evolution and migration of bed forms with characteristics that are in good agreement with experimental measurements. The URANS model, however, fails to excite the bed instability in the OSL channel but captures realistic dune evolution in the two large-scale meandering rivers. This finding is especially important as it demonstrates the potential of the VSL3D model as a powerful tool for simulating morphodynamic evolution under prototype conditions. To our knowledge, our work is the first attempt to simulate large-scale bed forms in waterways with an order of magnitude disparity in spatial scales, from the similar to 2.7 m wide OSL channel to the 27 m wide rivers. Accordingly, the height of the simulated dunes ranges from similar to 0.2 m to 2.0 m and the wavelength ranges from similar to 0.1 m to 50 m for the OSL and large-scale rivers, respectively. For all cases the statistical properties of the simulated bed forms are shown to agree well with those of bed forms observed in nature. (C) 2014 Elsevier Ltd. All rights reserved.

TI Integral expressions for mountain wave steepness SO WAVE MOTION LA English DT Article DE Mountain waves; Wave steepness; Internal gravity waves; Fourier transform methods; Hilbert transform ID HYDROSTATIC FLOW; LINEAR-THEORY; LEE WAVES; DRAG AB Expressions are derived for the wave steepness eta(z) of mountain waves, defined as the altitude (z) derivative of the vertical displacement eta. The derivation begins with a known Fourier integral for eta. The altitude derivative of the Fourier integral for eta introduces a singularity in the integrand that is not absolutely integrable at any altitude. It is seen, nonetheless, that the altitude derivative can be moved under the integral sign for altitudes above the ground, but not at the ground, for which a special expression is found relating wave steepness to the mountain height function. It is shown that the upwind limit of wave steepness at the ground is zero, but the downwind limit is nonzero in general, and an expression for the downwind limit in terms of the mountain height function is given. It is also found that the imaginary part of complex wave steepness diverges approaching the ground, and an asymptotic formula is given. The results are applied to three mountain topography shapes: elliptical Gaussian, circular with algebraic decay, and infinite ridge. (C) 2015 Elsevier B.V. All rights reserved.

These randomly occurring lags could act as short breaks and improve performance or as short interruptions and impair performance. The lags improved placekeeping accuracy, and to interpret this effect we developed a cognitive model of placekeeping operations, which accounts for the effect in terms of the lag making memory for recent performance more distinct. Self-report data suggest that rehearsal was the dominant strategy for maintaining placekeeping information during interruptions, and we incorporate a rehearsal mechanism in the model. To evaluate the model we developed a simple new goodness-of-fit test based on analysis of variance that offers an inferential basis for rejecting models that do not accommodate effects of experimental manipulations.

TI Heat generation rate measurement in a Li-ion cell at large C-rates through temperature and heat flux measurements SO JOURNAL OF POWER SOURCES LA English DT Article DE Lithium-ion batteries; Heat generation rate measurement; Heat flux sensor; Thermal conduction; Battery safety ID THERMAL-BEHAVIOR; HIGH-POWER; BATTERIES; ELECTRODES; SYSTEMS; MODEL AB Understanding the rate of heat generation in a Li-ion cell is critical for safety and performance of Li-ion cells and systems. Cell performance, cycle life, and system safety all depend on temperature distribution in the cell, which, in turn, depends on heat generation rate within the cell and on heat removal rate at the cell surface. Despite the existence of a number of theoretical models to predict heat generation rate, there is not much literature on experimental measurement at high C-rates. This paper reports measurement of heat generation rate from a Li-ion cell at high discharge rates, up to 9.6C, using measurements of cell temperature and surface heat flux. As opposed to calorimetry-based approaches, this method can be applied in situ to yield measurements of heat generation rate in laboratory or field use provided that at least one a priori test is performed to measure the temperature gradient within a cell in the same ambient condition. This method is based on simultaneous determination of heat stored and heat lost from the cell through heat flux and temperature measurements. A novel method is established for measurement of the internal temperature of the cell. Heat generation measurements are shown to agree with well-established theoretical models. The effect of actively cooling the cell is briefly discussed. (C) 2015 Elsevier B.V. All rights reserved. C1 [Drake, S. J.; Jain, A.] Univ Texas Arlington, Mech & Aerosp Engn Dept, Arlington, TX USA.

These measurements were complemented by gamma-ray excitation functions using the (n, n'gamma) reaction to include excited levels not resolved in the neutron detection measurements. The time-of-flight (TOF) technique was employed for background reduction in both neutron and gamma-ray measurements and for energy determination in neutron detection measurements. Previous reaction model evaluations relied primarily on neutron total cross sections and four (n, n(0)) and (n, n(1)) angular distributions in the 5 to 9 MeV range. The inclusion of more inelastic channels and measurements at lower incident neutron energies provide additional information on direct couplings between elastic and inelastic scattering as a function of angular momentum transfer. Reaction model calculations examining collective direct-coupling and compound absorption components were performed. (C) 2015 Elsevier B.V. All rights reserved. C1 [Vanhoy, J. R.; Watts, D.

This note demonstrates that those specialized models are unnecessary as the tools to explicitly find optimal fixed gains for arbitrary observable systems are already in the literature.

TI Restoration of images degraded by underwater turbulence using structure tensor oriented image quality (STOIQ) metric SO OPTICS EXPRESS LA English DT Article ID RESOLUTION; RECOVERY AB Recent advances in image processing for atmospheric propagation have provided a foundation for tackling the similar but perhaps more complex problem of underwater imaging, which is impaired by scattering and optical turbulence. As a result of these impairments underwater imagery suffers from excessive noise, blur, and distortion. Underwater turbulence impact on light propagation becomes critical at longer distances as well as near thermocline and mixing layers. In this work, we demonstrate a method for restoration of underwater images that are severely degraded by underwater turbulence. The key element of the approach is derivation of a structure tensor oriented image quality metric, which is subsequently incorporated into a lucky patch image processing framework. The utility of the proposed image quality measure guided by local edge strength and orientation is emphasized by comparing the restoration results to an unsuccessful restoration obtained with equivalent processing utilizing a standard isotropic metric. Advantages of the proposed approach versus three other state-of-the-art image restoration techniques are demonstrated using the data obtained in the laboratory water tank and in a natural environment underwater experiment. Quantitative comparison of the restoration results is performed via structural similarity index measure and normalized mutual information metric. (C)2015 Optical Society of America C1 [Kanaev, A.

We focus on the elastic constant associated with the Laplace pressure-induced deformation of the membrane upon capillary condensation, i.e., the pore-load modulus. We perform finite-element method (FEM) simulations of the adsorption-induced deformation of hexagonal and square lattices of cylindrical pores representing the membrane. We find that the pore-load modulus weakly depends on the geometrical arrangement of pores, and can be expressed as a function of porosity. We propose an analytical model which relates the pore-load modulus to the porosity and to the elastic properties of bulk silicon (Young's modulus and Poisson's ratio), and provides an excellent agreement with FEM results. We find good agreement between our experimental data and the predictions of the analytical model, with the Young's modulus of the pore walls slightly lower than the bulk value. This model is applicable to a large class of materials with morphologies similar to mesoporous silicon. Moreover, our findings suggest that liquid condensation experiments allow one to elegantly access the elastic constants of a mesoporous medium. (C) 2015 AIP Publishing LLC.

TI Resonant quantum efficiency enhancement of midwave infrared nBn photodetectors using one-dimensional plasmonic gratings SO APPLIED PHYSICS LETTERS LA English DT Article ID OPTICAL-PROPERTIES; COUPLER; PB; NI; AU AB We demonstrate up to 39% resonant enhancement of the quantum efficiency (QE) of a low dark current nBn midwave infrared photodetector with a 0.5 mu m InAsSb absorber layer. The enhancement was achieved by using a 1D plasmonic grating to couple incident light into plasmon modes propagating in the plane of the device. The plasmonic grating is composed of stripes of deposited amorphous germanium overlaid with gold. Devices with and without gratings were processed side-by-side for comparison of their QEs and dark currents. The peak external QE for a grating device was 29% compared to 22% for a mirror device when the illumination was polarized perpendicularly to the grating lines. Additional experiments determined the grating coupling efficiency by measuring the reflectance of analogous gratings deposited on bare GaSb substrates. (C) 2015 AIP Publishing LLC.

The observations were made with the Imaging Ultraviolet Spectrograph, a remote sensing instrument on the Mars Atmosphere and Volatile EvolutioN spacecraft orbiting Mars. Ionized magnesium caused the brightest emission from the planet's atmosphere for many hours, resulting from resonant scattering of solar ultraviolet light. Modeling suggests a substantial fluence of low-density dust particles 1-100 mu m in size, with the large amount and small size contrary to predictions. The event created a temporary planet-wide ionospheric layer below Mars' main dayside ionosphere. The dramatic meteor shower response at Mars is starkly different from the case at Earth, where a steady state metal layer is always observable but perturbations caused by even the strongest meteor showers are challenging to detect.

TI Growth and characterization of (110) InAs quantum well metamorphic heterostructures SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID MOLECULAR-BEAM EPITAXY; 2-DIMENSIONAL ELECTRON-GAS; GAAS-SURFACES; RELAXATION; INTERFACE; STRAIN; FILMS; DOTS; INSB; HETEROEPITAXY AB An understanding of the growth of (110) quantum wells (QWs) is of great importance to spin systems due to the observed long spin relaxation times. In this article, we report on the metamorphic growth and characterization of high mobility undoped InAs (110) QWs on GaAs (110) substrates. A low-temperature nucleation layer reduces dislocation density, results in tilting of the subsequent buffer layer and increases the electron mobility of the QW structure. The mobility varies widely and systematically (4000-16 000 cm(2)/Vs at room temperature) with deposition temperature and layer thicknesses. Low-temperature transport measurements exhibit Shubnikov de-Haas oscillations and quantized plateaus in the quantum Hall regime. (C) 2015 AIP Publishing LLC.

The case is based on observations obtained during the RACORO Campaign (Routine Atmospheric Radiation Measurement (ARM) Aerial Facility (AAF) Clouds with Low Optical Water Depths (CLOWD) Optical Radiative Observations) at the ARM Climate Research Facility's Southern Great Plains site. The LES models are driven by continuous large-scale and surface forcings and are constrained by multimodal and temporally varying aerosol number size distribution profiles derived from aircraft observations. We compare simulated cloud macrophysical and microphysical properties with ground-based remote sensing and aircraft observations. The LES simulations capture the observed transitions of the evolving cumulus-topped boundary layers during the three daytime periods and generally reproduce variations of droplet number concentration with liquid water content (LWC), corresponding to the gradient between the cloud centers and cloud edges at given heights. The observed LWC values fall within the range of simulated values; the observed droplet number concentrations are commonly higher than simulated, but differences remain on par with potential estimation errors in the aircraft measurements. Sensitivity studies examine the influences of bin microphysics versus bulk microphysics, aerosol advection, supersaturation treatment, and aerosol hygroscopicity. Simulated macrophysical cloud properties are found to be insensitive in this nonprecipitating case, but microphysical properties are especially sensitive to bulk microphysics supersaturation treatment and aerosol hygroscopicity.

TI Selection and Evaluation of Reference Genes for Reverse Transcription-Quantitative PCR Expression Studies in a Thermophilic Bacterium Grown under Different Culture Conditions SO PLOS ONE LA English DT Article ID REAL-TIME PCR; IN-VITRO GROWTH; RT-PCR; THERMUS-SCOTODUCTUS; GLYCERALDEHYDE-3-PHOSPHATE DEHYDROGENASE; DEINOCOCCUS-RADIODURANS; EXTREME THERMOPHILE; HOUSEKEEPING GENES; IDENTIFICATION; NORMALIZATION AB The phylum Deinococcus-Thermus is a deeply-branching lineage of bacteria widely recognized as one of the most extremophilic. Members of the Thermus genus are of major interest due to both their bioremediation and biotechnology potentials. However, the molecular mechanisms associated with these key metabolic pathways remain unknown. Reverse-transcription quantitative PCR (RT-qPCR) is a high-throughput means of studying the expression of a large suite of genes over time and under different conditions. The selection of a stably-expressed reference gene is critical when using relative quantification methods, as target gene expression is normalized to expression of the reference gene. However, little information exists as to reference gene selection in extremophiles. This study evaluated 11 candidate reference genes for use with the thermophile Thermus scotoductus when grown under different culture conditions. Based on the combined stability values from BestKeeper and NormFinder software packages, the following are the most appropriate reference genes when comparing: (1) aerobic and anaerobic growth: TSC_c19900, polA2, gyrA, gyrB; (2) anaerobic growth with varied electron acceptors: TSC_c19900, infA, pfk, gyrA, gyrB; (3) aerobic growth with different heating methods: gyrA, gap, gyrB; (4) all conditions mentioned above: gap, gyrA, gyrB. The commonly-employed rpoC does not serve as a reliable reference gene in thermophiles, due to its expression instability across all culture conditions tested here. As extremophiles exhibit a tendency for polyploidy, absolute quantification was employed to determine the ratio of transcript to gene copy number in a subset of the genes. A strong negative correlation was found to exist between ratio and threshold cycle (C-T) values, demonstrating that C-T changes reflect transcript copy number, and not gene copy number, fluctuations. Even with the potential for polyploidy in extremophiles, the results obtained via absolute quantification indicate that relative quantification is appropriate for RT-qPCR studies with this thermophile.

CA STAR Collaboration TI Observation of Charge Asymmetry Dependence of Pion Elliptic Flow and the Possible Chiral Magnetic Wave in Heavy-Ion Collisions SO PHYSICAL REVIEW LETTERS LA English DT Article ID RELATIVISTIC NUCLEAR COLLISIONS; MODEL; VIOLATION; MATTER; FIELD; QCD AB We present measurements of pi(-) and pi(+) elliptic flow, v(2), at midrapidity in Au + Au collisions at root s(NN) = 200, 62.4, 39, 27, 19.6, 11.5, and 7.7 GeV, as a function of event-by-event charge asymmetry, A(ch), based on data from the STAR experiment at RHIC. We find that pi(-) (pi(+)) elliptic flow linearly increases (decreases) with charge asymmetry for most centrality bins at root s(NN) = 27 GeV and higher. At root s(NN) = 200 GeV, the slope of the difference of v(2) between pi(-) and pi(+) as a function of A(ch) exhibits a centrality dependence, which is qualitatively similar to calculations that incorporate a chiral magnetic wave effect. Similar centrality dependence is also observed at lower energies. C1 [Adamczyk, L.; Fulek, L.; Sikora, R.] AGH Univ Sci & Technol, PL-30059 Krakow, Poland. [Krueger, K.; Spinka, H. M.; Underwood, D.

TI Updated search for spectral lines from Galactic dark matter interactions with pass 8 data from the Fermi Large Area Telescope SO PHYSICAL REVIEW D LA English DT Article ID CANDIDATES; GALAXIES; DENSITY AB Dark matter in the Milky Way may annihilate directly into. rays, producing a monoenergetic spectral line. Therefore, detecting such a signature would be strong evidence for dark matter annihilation or decay. We search for spectral lines in the Fermi Large Area Telescope observations of the Milky Way halo in the energy range 200 MeV-500 GeV using analysis methods from our most recent line searches. The main improvements relative to previous works are our use of 5.8 years of data reprocessed with the Pass 8 event-level analysis and the additional data resulting from the modified observing strategy designed to increase exposure of the Galactic center region. We search in five sky regions selected to optimize sensitivity to different theoretically motivated dark matter scenarios and find no significant detections. In addition to presenting the results from our search for lines, we also investigate the previously reported tentative detection of a line at 133 GeV using the new Pass 8 data.

TI Fingerprints of the initial conditions on the density profiles of cold and warm dark matter haloes SO MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY LA English DT Article DE galaxies: dwarf; galaxies: haloes; cosmology: theory; dark matter ID INNER STRUCTURE; ACCRETION HISTORY; SECONDARY INFALL; GALAXY FORMATION; MASS; UNIVERSAL; DEPENDENCE; COSMOLOGY; CLUSTERS; MODELS AB We use N-body simulations of dark matter haloes in cold dark matter (CDM) and a large set of different warm dark matter (WDM) cosmologies to demonstrate that the spherically averaged density profile of dark matter haloes has a shape that depends on the power spectrum of matter perturbations. Density profiles are steeper in WDM but become shallower at r < 0.01R(vir). Virialization isotropizes the velocity dispersion in the inner regions of the halo but does not erase the memory of the initial conditions in phase space. The location of the observed deviations from CDM in the density profile and in phase space can be directly related to the ratio between the halo mass and the filtering mass and are most evident in small mass haloes, even for a 34 keV thermal relic WDM. The rearrangement of mass within the haloes supports analytic models of halo structure that include angular momentum. We also find evidence of a dependence of the slope of the inner density profile in CDM cosmologies on the halo mass with more massive haloes exhibiting steeper profiles, in agreement with the model predictions and with previous simulation results. Our work complements recent studies of microhaloes near the filtering scale in CDM and strongly argue against a universal shape for the density profile.

TI A CONSISTENT PICTURE EMERGES: A COMPACT X-RAY CONTINUUM EMISSION REGION IN THE GRAVITATIONALLY LENSED QUASAR SDSS J0924+0219 SO ASTROPHYSICAL JOURNAL LA English DT Article DE accretion, accretion disks; gravitational lensing: micro; quasars: general ID ACTIVE GALACTIC NUCLEI; MICROLENSING LIGHT CURVES; HUBBLE-SPACE-TELESCOPE; ACCRETING BLACK-HOLES; FLUX RATIO ANOMALIES; TIME DELAYS; CHANDRA OBSERVATIONS; MASS-DISTRIBUTION; EMITTING REGIONS; EINSTEIN RINGS AB We analyze the optical, UV, and X-ray microlensing variability of the lensed quasar SDSS J0924+ 0219 using six epochs of Chandra data in two energy bands (spanning 0.4-8.0 keV, or 1-20 keV in the quasar rest frame), 10 epochs of F275W (rest-frame 1089 angstrom) Hubble Space Telescope data, and high-cadence R-band (rest-frame 2770 angstrom) monitoring spanning 11 years. Our joint analysis provides robust constraints on the extent of the X-ray continuum emission region and the projected area of the accretion disk. The best-fit half-light radius of the soft X-ray continuum emission region is between 5 x 10(13) and 10(15) cm, and we find an upper limit of 10(15) cm for the hard X-rays. The best-fit soft-band size is about 13 times smaller than the optical size, and roughly 7GM(BH)/c(2) for a 2.8 x 10(8) M-circle dot black hole, similar to the results for other systems. We find that the UV emitting region falls in between the optical and X-ray emitting regions at 10(14) cm < r(1/2,UV) <3x10(15) cm. Finally, the optical size is significantly larger, by 1.5 sigma, than the theoretical thin-disk estimate based on the observed, magnification-corrected I-band flux, suggesting a shallower temperature profile than expected for a standard disk.

We reconstruct the projected matter distribution from a joint weak-lensing analysis of two-dimensional shear and azimuthally integrated magnification constraints, the combination of which allows us to break the mass-sheet degeneracy. The resulting mass distribution reveals elongation with an axis ratio of similar to 0.7 in projection, aligned well with the distributions of cluster galaxies and intracluster gas. When assuming a spherical halo, our full weak-lensing analysis yields a projected halo concentration of c(200c)(2D) = 8.9 +/- 1.1 (c(vir)(2D) similar to 11), consistent with and improved from earlier weak-lensing work. We find excellent consistency between independent weak and strong lensing in the region of overlap. In a parametric triaxial framework, we constrain the intrinsic structure and geometry of the matter and gas distributions, by combining weak/strong lensing and X-ray/SZE data with minimal geometric assumptions. We show that the data favor a triaxial geometry with minor-major axis ratio 0.39 +/- 0.15 and major axis closely aligned with the line of sight (22 degrees +/- 10 degrees). We obtain a halo mass M-200c (1.2 +/- 0.2) x 10(15) M-circle dot h(-1). and a halo concentration c(200c)= 8.4 +/- 1.3, which overlaps with the greater than or similar to 1 sigma tail of the predicted distribution. The shape of the gas is rounder than the underlying matter but quite elongated with minor-major axis ratio 0.60 +/- 0.14. The gas mass fraction within 0.9 Mpc is 10(-2)(+3)%, a typical value for high-mass clusters. The thermal gas pressure contributes to similar to 60% of the equilibrium pressure, indicating a significant level of non-thermal pressure support. When compared to Planck ' s hydrostatic mass estimate, our lensing measurements yield a spherical mass ratio of MPlanck/MGL= 0.70 +/- 0.15 and 0.58 +/- 0.10 with and without corrections for lensing projection effects, respectively.

Given the unique stressors experienced by U.S. service members, including lengthy and/or multiple deployments, this study aimed to examine the associations of recent divorce on health and military outcomes among a cohort of U.S. service members. Methods: Millennium Cohort participants from the first enrollment panel, married at baseline (2001-2003), and married or divorced at follow-up (2004-2006), (N = 29,314). Those divorced were compared to those who remained married for mental, behavioral, physical health, and military outcomes using logistic regression models. Results: Compared to those who remained married, recently divorced participants were significantly more likely to screen positive for new-onset posttraumatic stress disorder, depression, smoking initiation, binge drinking, alcohol-related problems, and experience moderate weight gain. However, they were also more likely be in the highest 15th percentile of physical functioning, and be able to deploy within the subsequent 3-year period after divorce. Conclusions: Recent divorce among military members was associated with adverse mental health outcomes and risky behaviors, but was also associated with higher odds of subsequent deployment. Attention should be given to those recently divorced regarding mental health and substance abuse treatment and prevention strategies.

At equilibrium, avobenzone exists as a chelated-enol characterized by a strong intramolecular hydrogen bond. Many nanosecond- to,microsecond-scale experiments have shown that the photoisomerization involves several tionchelated enol (NCE) isomers and reaction paths, including some that reduce avobenzone's efficacy as a sunscreen. Because some of the NCE isomers are unstable, these experiments do, not directly measure their spectroscopic sighatOres. Here, we report the dynamics of airobenzone on the picosecond time scale. We excite avobenzone at 350 nm and observe the formation and relaxation of new isomers and vibrationally excited species with broadband visible probe pulses and 266 nm probe pulses. Our results show the first direct evidence of two unstable NCE isomers and establish the lifetimes of and the branching ratio between these isomers.

We consider intrinsic spin-orbit interactions (ISOIs) that are confined within the N wire and absent in the s-wave superconducting electrodes (S). Using experimentally feasible parameters, we demonstrate that the coupling of the ISOIs and spin moment of the spin-active interface results in maximum singlet-triplet conversion and accumulation of spin current density at the corners of the N wire nearest the spin-active interface. By solely modulating the superconducting phase difference, we show how the opposing parities of the charge and spin currents provide an effective venue to experimentally examine pure edge spin currents not accompanied by charge currents. These effects occur in the absence of externally imposed fields and moreover are insensitive to the arbitrary orientations of the interface spin moment. The experimental implementation of these robust edge phenomena are also discussed. C1 [Alidoust, Mohammad] Univ Basel, Dept Phys, CH-4056 Basel, Switzerland.

The device allows for easy access to the individual fibers while offering similar properties to multicore optical fiber. To demonstrate, a two-axis inclinometer is rapidly developed and evaluated for its performance. In this example, three fibers containing fiber Bragg gratings written in single-mode fiber are metalized and attached to each other using a low-temperature indium-based solder.

TI Morphological study of Insoluble Organic Matter from carbonaceous chondrites: Correlation with petrologic grade SO GEOCHIMICA ET COSMOCHIMICA ACTA LA English DT Article ID INTERPLANETARY DUST PARTICLES; TAGISH LAKE METEORITE; PRIMITIVE METEORITES; AQUEOUS ALTERATION; INTERSTELLAR GRAINS; MURCHISON METEORITE; PARENT BODIES; ORIGIN; EVOLUTION; GLOBULES AB The major form of organic material delivered to Earth from an extraterrestrial origin is Insoluble Organic Matter (IOM). A morphological study of IOM in the CR (Renazzo-type) and CM (Mighei-type) carbonaceous chondrites was performed in order to constrain its origins and processing history. IOM residues from the following CR chondrites: GRO 95577 (CR1), Al Rais (CR1/2), EET 92042 (CR2), QUE 99177 (CR3) and the CM chondrites: MET 01070 (CM2.2), Cold Bokkeveld (CM2.3), Murchison (CM2.4) and QUE 97990 (CM2.5) were studied using Annular Dark Field STEM imaging. Characteristic features of the IOM, organic nanoglobules, were manually identified and measured for their abundances and size distributions. The IOM residues were also compared holistically for their degree of average 'roughness' or 'coarsening' using fractal image analysis. Manually identified nanoglobules have abundances making up less than 10% of the total IOM, which is consistent with previous studies. Their measured abundances do not correlate with petrologic grade. Thus parent body processing did not systematically deplete their abundances. The IOM is however on average 'smoother' or 'coarser' in the more altered chondrites, demonstrated by a lower fractal dimension using fractal box counting (D-B). The D-B values for the IOM in the CR chondrites are distinctive: QUE 99177 has the largest DB value (average = 1.54 +/- 0.004) and GRO 99577 has the lowest (average = 1.45 + 0.011). Al Rais and EET 92042 have IOM with average DB values within this range (average, 1.46 + 0.009 and 1.50 +/- 0.006). The CMs record a similar but less distinctive trend in DB, with QUE 97990 having the largest value (1.52 +/- 0.004), MET 01070 the lowest (1.45 +/- 0.019), and Cold Bokkeveld (1.50 +/- 0.011) and Murchison (1.49 +/- 0.017) equivalent to one another within error. The identified nanoglobules in the IOM of the CM chondrites are on average larger than those in the CR chondrites. The 'coarsening' or 'smoother' texture of the IOM (lower DB) in the more altered chondrites coupled with a tentative increase in the size of large features (identified nanoglobules) demonstrates that the aqueous processes leading to the lower petrologic types also formed the overall IOM morphology. In addition, observations of fluid-like textures more frequently found in the more altered carbonaceous chondrite residues suggests that organic and aqueous fluids determined at least some of these morphologies. The polymerization of organic solutions is consistent with these morphologies. Their formation conditions are more favorable under the containment of carbonaceous chondrite parent bodies.

TI Improved synthesis and properties of aryl ether-based oligomeric phthalonitrile resins and polymers SO POLYMER LA English DT Article DE Aryl ether; Phthalonitrile; High temperature ID CARBON FIBER COMPOSITES; OXIDATIVE STABILITY; BISPHENOL-A; TEMPERATURE; CURE; POLYMERIZATION AB A versatile scheme to produce a multiple aromatic ether-linked phthalonitrile has been developed and applied to the preparation of two unique resin systems. The oligomeric phthalonitrile monomer was prepared from the reaction of an excess amount of bisphenol A or bisphenol A6F with 1,3-dibromobenzene in the presence of K2CO3 as the base in a N,N-dimethylformamide/toluene solvent mixture, followed by end-capping with 4-nitrophthalonitrile in a two-step, one-pot reaction. Both phthalonitrile resin systems exhibited excellent viscosities for molding various shaped articles and were thermally cured to yield crosslinked polymers. Each bisphenol-based polymer also demonstrated superb mechanical properties and thermo-oxidative stability while absorbing less than 1% percent water by weight. The two systems differed greatly in their relative reactivity toward the curing additive bis(4-[3-aminophenoxy]phenyl)-sulfone (m-BAPS). The presence of the electron withdrawing CF3 groups on the bisphenol A6F resulted in a faster curing reaction to the thermoset polymer but weaker mechanical properties and less overall thermal stability relative to the bisphenol A-containing resin. The bisphenol A6F polymer showed a lower overall water absorption but exhibited a comparable dielectric constant relative to the bisphenol A polymer. Published by Elsevier Ltd.

TI GALAXY CLUSTER SCALING RELATIONS BETWEEN BOLOCAM SUNYAEV-ZEL'DOVICH EFFECT AND CHANDRA X-RAY MEASUREMENTS SO ASTROPHYSICAL JOURNAL LA English DT Article DE galaxies: clusters: general; galaxies: clusters: intracluster medium ID SOUTH-POLE TELESCOPE; WEAK-LENSING MASSES; 720 SQUARE DEGREES; COSMOLOGICAL CONSTRAINTS; MACS J0717.5+3745; SECONDARY CALIBRATORS; TEMPERATURE RELATION; OBSERVED GROWTH; RICH CLUSTERS; XMM-NEWTON AB We present scaling relations between the integrated Sunyaev-Zel'dovich effect (SZE) signal, Y-SZ, its X-ray analogue, Y-X = MgasTX, and total mass, M-tot, for the 45 galaxy clusters in the Bolocam X-ray SZ (BOXSZ) sample. All parameters are integrated within r(2500). Y-2500 values are measured using SZE data collected with Bolocam, operating at 140 GHz at the Caltech Submillimeter Observatory. The temperature, T-X, and mass, M-gas,M- 2500, of the intracluster medium are determined using X-ray data collected with Chandra, and M-tot is derived from M-gas assuming a constant gas mass fraction. Our analysis accounts for several potential sources of bias, including selection effects, contamination from radio point sources, and the loss of SZE signal due to noise filtering and beam-smoothing effects. We measure the Y-2500-Y-X scaling to have a power-law index of 0.84 +/- 0.07, and a fractional intrinsic scatter in Y-2500 of (21 +/- 7)% at fixed Y-X, both of which are consistent with previous analyses. We also measure the scaling between Y-2500 and M-2500, finding a power-law index of 1.06 +/- 0.12 and a fractional intrinsic scatter in Y-2500 at fixed mass of (25 +/- 9)%. While recent SZE scaling relations using X-ray mass proxies have found power-law indices consistent with the self-similar prediction of 5/3, our measurement stands apart by differing from the self-similar prediction by approximately 5 sigma. Given the good agreement between the measured Y-2500-Y-X scalings, much of this discrepancy appears to be caused by differences in the calibration of the X-ray mass proxies adopted for each particular analysis.

TI DISCOVERY OF GAMMA-RAY PULSATIONS FROM THE TRANSITIONAL REDBACK PSR J1227-4853 SO ASTROPHYSICAL JOURNAL LA English DT Article DE pulsars: individual (J1227-4853); binaries: eclipsing; gamma rays: stars ID LARGE-AREA TELESCOPE; BINARY MILLISECOND PULSAR; HIGH-ENERGY EMISSION; BLACK-WIDOW PULSARS; X-RAY; XSS J12270-4859; LIGHT CURVES; NEUTRON-STARS; STATE CHANGE; SLOT GAPS AB The 1.69 ms spin period of PSR J1227-4853 was recently discovered in radio observations of the low-mass X-ray binary XSS J12270-4859 following the announcement of a possible transition to a rotation-powered millisecond pulsar state, inferred from decreases in optical, X-ray, and gamma-ray flux from the source. We report the detection of significant (5s) gamma-ray pulsations after the transition, at the known spin period, using similar to 1 year of data from the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope. The gamma-ray light curve of PSR J1227-4853 can be fit by one broad peak, which occurs at nearly the same phase as the main peak in the 1.4 GHz radio profile. The partial alignment of light-curve peaks in different wavebands suggests that at least some of the radio emission may originate at high altitude in the pulsar magnetosphere, in extended regions co-located with the gamma-ray emission site. We folded the LAT data at the orbital period, both pre- and post-transition, but find no evidence for significant modulation of the gamma-ray flux. Analysis of the gamma-ray flux over the mission suggests an approximate transition time of 2012 November 30. Continued study of the pulsed emission and monitoring of PSR J1227-4853, and other known redback systems, for subsequent flux changes will increase our knowledge of the pulsar emission mechanism and transitioning systems.

TI Einstein@Home DISCOVERY OF A PALFA MILLISECOND PULSAR IN AN ECCENTRIC BINARY ORBIT SO ASTROPHYSICAL JOURNAL LA English DT Article DE methods: data analysis; pulsars: general; pulsars: individual (J1950+2414); stars: neutron ID GAMMA-RAY PULSARS; SYSTEM PSR J1023+0038; SHAPIRO DELAY; RADIO PULSARS; GENERAL-RELATIVITY; GLOBULAR-CLUSTERS; RECYCLED PULSARS; 1ST DISCOVERIES; TIMING PACKAGE; GALACTIC PLANE AB We report the discovery of the millisecond pulsar (MSP) PSR J1950+2414 (P = 4.3 ms) in a binary system with an eccentric (e = 0.08) 22 day orbit in Pulsar Arecibo L-band Feed Array survey observations with the Arecibo telescope. Its companion star has a median mass of 0.3M(circle dot) and is most likely a white dwarf (WD). Fully recycled MSPs like this one are thought to be old neutron stars spun-up by mass transfer from a companion star. This process should circularize the orbit, as is observed for the vast majority of binary MSPs, which predominantly have orbital eccentricities e < 0.001. However, four recently discovered binary MSPs have orbits with 0. 027 < e < 0.44; PSR J1950+2414 is the fifth such system to be discovered. The upper limits for its intrinsic spin period derivative and inferred surface magnetic field strength are comparable to those of the general MSP population. The large eccentricities are incompatible with the predictions of the standard recycling scenario: something unusual happened during their evolution. Proposed scenarios are (a) initial evolution of the pulsar in a triple system which became dynamically unstable, (b) origin in an exchange encounter in an environment with high stellar density, (c) rotationally delayed accretion-induced collapse of a super-Chandrasekhar WD, and (d) dynamical interaction of the binary with a circumbinary disk. We compare the properties of all five known eccentric MSPs with the predictions of these formation channels. Future measurements of the masses and proper motion might allow us to firmly exclude some of the proposed formation scenarios.

TI Robust Performance of Marginal Pacific Coral Reef Habitats in Future Climate Scenarios SO PLOS ONE LA English DT Article ID OCEAN ACIDIFICATION; TROPICAL CYCLONES; ECOSYSTEMS; DISTRIBUTIONS; ENVIRONMENTS; BIODIVERSITY; SERVICES; MODELS AB Coral reef ecosystems are under dual threat from climate change. Increasing sea surface temperatures and thermal stress create environmental limits at low latitudes, and decreasing aragonite saturation state creates environmental limits at high latitudes. This study examines the response of unique coral reef habitats to climate change in the remote Pacific, using the National Center for Atmospheric Research Community Earth System Model version 1 alongside the species distribution algorithm Maxent. Narrow ranges of physicochemical variables are used to define unique coral habitats and their performance is tested in future climate scenarios. General loss of coral reef habitat is expected in future climate scenarios and has been shown in previous studies. This study found exactly that for most of the predominant physico-chemical environments. However, certain coral reef habitats considered marginal today at high latitude, along the equator and in the eastern tropical Pacific were found to be quite robust in climate change scenarios. Furthermore, an environmental coral reef refuge previously identified in the central south Pacific near French Polynesia was further reinforced. Studying the response of specific habitats showed that the prevailing conditions of this refuge during the 20th century shift to a new set of conditions, more characteristic of higher latitude coral reefs in the 20th century, in future climate scenarios projected to 2100.

We show that these spectral features can provide a measure of the parameters that govern the optical pumping process: electron-nuclear cross-relaxation rate, Bohr radius and fractional occupancy of the optically relevant defect (ORD), and electron polarization at the ORD. Applying a model of the spatial and temporal evolution of the nuclear spins under optical pumping to P-31 in semi-insulating InP we find an ORD Bohr radius of 6 nm, independent of the electron polarization used to fit the data, confirming the ORD is a shallow donor. For an electron polarization of -0.15, the ORD fractional occupancy is 0.02, leading to an electron-nuclear cross-relaxation time of 0.20 s and a hyperfine frequency shift of 8.1 kHz for super-bandgap irradiation. Allowing the electron polarization to vary in the model constrained to the hyperfine shift data, we find the fractional occupancy and electron-nuclear cross-relaxation rate to be approximately inversely proportional to the electron polarization. From the long-time evolution of the nuclear polarization we calculate an ORD density of 5 x 10(15) cm(-3). C1 [Miller, J. B.; Klug, C. A.; Sauer, K. L.; Yesinowski, J.

Samples were grown lattice-matched to InP by molecular beam epitaxy and two different growth temperatures of 450 degrees C and 325 degrees C were compared. Interpolated bandgap energies suggest that the development of this alloy would extend the range of available direct bandgaps attainable in materials lattice-matched to InP to energies as high as 1.81 eV. However, the peak energy of the observed PL emission is anomalously low for samples grown at both temperatures, with the 450 degrees C sample showing larger deviation from the expected bandgap. A fit of the integrated PL intensity (I) to an I proportional to P-k dependence, where P is the incident power density, yields characteristic coefficients k = 1.05 and 1.18 for the 450 degrees C and 325 degrees C samples, respectively. This indicates that the PL from both samples is dominated by excitonic recombination. A blue-shift in the peak emission energy as a function of P, along with an S-shaped temperature dependence, is observed. These trends are characteristic of spatially-indirect recombination associated with compositional variations. The energy depth of the confining potential, as derived from the thermal quenching of the photoluminescence, is 0.14 eV for the 325 degrees C sample, which is consistent with the red-shift of the PL emission peak relative to the expected bandgap energy. This suggests that compositional variation is the primary cause of the anomalously low PL emission peak energy. The higher energy PL emission of the 325 degrees C sample, relative to the 450 degrees C sample, is consistent with a reduction of the compositional fluctuations. The lower growth temperature is therefore considered more favorable for further growth optimization. (C) 2015 AIP Publishing LLC.

TI Enhancing secondary yield of a diamond amplifier using a nitrogen layer SO JOURNAL OF APPLIED PHYSICS LA English DT Article ID SINGLE-CRYSTAL AB A thin nitrogen-doped layer less than 4% of the total thickness in diamond thin film amplifier is shown to reduce losses of generated secondaries to the back contact, generated by a high energy primary electron beam compared to a thin film without the substitutional nitrogen layer modification. Simulation indicates that the losses due to absorption of diffusing electrons by the back contact may be considerably reduced by a factor of 2 (depending on field across the film, width of the nitrogen layer, and boron doping level), thereby mitigating undesirable effects associated with trace amounts of boron.

TI Uniform circular array pattern synthesis using second-order cone programming SO IET MICROWAVES ANTENNAS & PROPAGATION LA English DT Article ID OPTIMIZATION; SDPT3 AB Here, the authors formulate second-order cone programs (SOCPs) for synthesising complex weights for far-field directional (single-point mainbeam) patterns for narrowband arrays. These formulations, while constructed here with the uniform circular array (UCA) in mind, are actually quite general in that they control the arbitrary-pol sidelobe level (SLL) and co-pol signal-to-noise ratio loss relative to ideal by minimising either while upper bounding the other. The SLL can be addressed in either an L-infinity sense or an L1 sense, and elements are assumed characterised by individual embedded complex patterns, modelled or measured, and so need not be identical. Conformal arrays are the obvious application, but we leave that for others and here instead apply the SOCPs to UCAs of directional elements. Design examples assume an antipodal Vivaldi element design with an embedded element pattern obtained through simulation using appropriate unit-cell boundary conditions. Rotation and translation of that simulated pattern provides embedded element patterns for all elements of the circular array.

However, little research exists to examine associated serological and health effects, especially in adults. Method: We retrospectively examined 416 paired serum specimens from U.S. military subjects who had received the inactivated polio vaccine (IPV) alone or in combination with either 1 other vaccine (<3 group) or 4 other vaccines (>4 group). Each of the 2 groups was subdivided into 2 subgroups in which Tdap was present or absent. Results: The >4 group was associated with a higher proportion of polio seroconversions than the <3 group (95% vs. 58%, respectively, p<0.01). Analysis of the <3 subgroup that excluded Tdap vs. the >4 subgroup that excluded Tdap showed no difference between them (p>0.1). However, the >4 subgroup that included Tdap had significantly more seroconversions than either the <3 subgroup that excluded Tdap or the >4 subgroup that excluded Tdap (p<0.01). Overall, at least 98% of subjects were at or above the putative level of seroprotection both pre- and post-vaccination, yet at least 81% of subjects seroconverted. In an analysis of 400 of the subjects in which clinic in- and outpatient encounters were counted over the course of 1 year following vaccinations, there was no significant difference between the 2 groups (p>0.1). Conclusion: A combination of >4 vaccines including IPV appeared to have an immunopotentiation effect on polio seroconversion, and Tdap in particular was a strong candidate for an important role. The dose of IPV we studied in our subjects, who already had a high level of seroprotection, acted as a booster. In addition, there appear to be no negative health consequences from receiving few versus more multiple simultaneous vaccinations. Published by Elsevier Ltd.

To better understand the mechanisms that give rise to high conductivity, the goal of this work is to correlate Li site occupancy with Li-ion transport. Toward this goal, the Li site occupancy is studied in cubic garnet as a function of Li concentration over the compositions range: Li7-xLa3Zr2-xTaxO12 (x = 0.5, 0.75, and 1.5). The distribution of Li between the two interstitial sites (24d and 96h) is determined using neutron and synchrotron diffraction. The bulk conductivity is measured on >97% relative density polycrystalline specimens to correlate Li-ion transport as a function of Li site occupancy. It is determined that the conductivity changes nonlinearly with the occupancy of the octahedral (96h) Li site. It is shown that the effective carrier concentration is dependent on the Li site occupancy and suggests that this is a consequence of significant carrier-carrier coulombic interactions. Furthermore, the observation of maximum conductivity near Li = 6.5 mol is explained.

TI Suppressing the Neurospora crassa circadian clock while maintaining light responsiveness in continuous stirred tank reactors SO SCIENTIFIC REPORTS LA English DT Article ID FEEDBACK LOOPS; RHYTHMICITY; SYSTEM; GENES; HOMEOSTASIS; FREQUENCY; CULTURES; MUTANTS; CLONING; INPUT AB Neurospora crassa has been utilized as a model organism for studying biological, regulatory, and circadian rhythms for over 50 years. These circadian cycles are driven at the molecular level by gene transcription events to prepare for environmental changes. N. crassa is typically found on woody biomass and is commonly studied on agar-containing medium which mimics its natural environment. We report a novel method for disrupting circadian gene transcription while maintaining light responsiveness in N. crassa when held in a steady metabolic state using bioreactors. The arrhythmic transcription of core circadian genes and downstream clock-controlled genes was observed in constant darkness (DD) as determined by reverse transcription-quantitative PCR (RT-qPCR). Nearly all core circadian clock genes were up-regulated upon exposure to light during 11hr light/dark cycle experiments under identical conditions. Our results demonstrate that the natural timing of the robust circadian clock in N. crassa can be disrupted in the dark when maintained in a consistent metabolic state. Thus, these data lead to a path for the production of industrial scale enzymes in the model system, N. crassa, by removing the endogenous negative feedback regulation by the circadian oscillator.

Along the lines of previous preon models positing a substructure to explain these aspects, Bilson-Thompson showed how the first family of elementary particles is realized as the crossings of braids made of three strands, with charges resulting from twists of those strands with certain conditions; in this topological model, there are only two distinct neutrino states. Modeling the particles as braids implies these braids must be the representation space of a Lie algebra, giving the symmetries of the standard model. In this paper, this representation is made explicit, obtaining the raising operators associated with the Lie algebra of SU (5), one of the earliest grand unified theories. Because the braids form a group, the action of these operators are braids themselves, leading to their identification as gauge bosons. Possible choices for the other two families are also given. Although this realization of particles as braids is lacking a dynamical framework, it is very suggestive, especially when considered as a natural method of adding matter to loop quantum gravity.

We examined whether military service, including deployment and combat experience, were related to smoking initiation and relapse. Methods. We included older (panel 1) and younger (panel 2) participants in the Millennium Cohort Study. Never smokers were followed for 3 to 6 years for smoking initiation, and former smokers were followed for relapse. Complementary log-log regression models estimated the relative risk (RR) of initiation and relapse by military exposure while adjusting for demographic, health, and lifestyle factors. Results. Deployment with combat experience predicted higher initiation rate (panel 1: RR = 1.44; 95% confidence interval [CI] = 1.28, 1.62; panel 2: RR = 1.26; 95% CI = 1.04, 1.54) and relapse rate (panel 1 only: RR = 1.48; 95% CI = 1.36, 1.62). Depending on the panel, previous mental health disorders, life stressors, and other military and nonmilitary characteristics independently predicted initiation and relapse. Conclusions. Deployment with combat experience and previous mental disorder may identify military service members in need of intervention to prevent smoking initiation and relapse.

Secretary of the Navy Ray Mabus stated, "each $1 increase in the price of a barrel of oil results in a $30 million bill for the Navy and Marine Corps. In 2011 and 2013, price fluctuations added an unplanned $3 billion to the Department of Defense's (DoD) fuel expenses! While fluctuating fuel costs dramatically influence operating budgets, energy supply and consumption have an enormous impact on the warfighter's readiness and capability. Warfighter capability in respect to energy is primarily concerned with five major variables: budgets, supply, consumption, maintenance, and operations. As the Navy continues to emphasize energy security in a fiscally constrained environment, many energy saving technologies, tools, and procedures are being developed and implemented. This will allow the Navy to increase presence with less fuel while reducing supply chain vulnerabilities. This paper will address the impact of fluctuating fuel prices, the supply and logistics of fuels at-sea, and the importance of energy efficiency as a capability to be exploited. It will introduce means to reduce energy consumption by energy efficient technologies, operation and system commands planning and decisions, and maintenance actions. Finally, it will discuss the importance of an integrated energy management system that can be used to measure the effectiveness of these efforts, provide actionable plant alignment and equipment maintenance recommendations, and inform future fuel budgets.

TI Human Endurance in Ship Design SO NAVAL ENGINEERS JOURNAL LA English DT Article AB In the January 2013 U.S. Naval Institute Proceedings article entitled "A Sea Change in Standing Watch," Dr. Nita Shattuck and I discussed the operational advantages of a four-section, circadian watch rotation to mitigate shipboard fatigue [34-39]. Nearly two years and several studies later, numerous ships have adopted similar watch rotations and data have continued to show positive effects from this approach. These studies have revealed that the best circadian rotations require a four-section watch to maintain; however, most U.S. Navy ships are constrained [by the design of the watch bill and the berthing spaces] to just enough personnel to support a three-section watch. "A Sea Change in Standing Watch" was written for the ship's crew and leadership and provided some "best practices" to reduce fatigue, but the restrictions imposed by ship design and manning policies can limit the activities' effectiveness. So there is a need for a discussion regarding a different group the naval engineers who design Navy ships. This article is intended as natural follow-up for them. My qualifications for writing the previous article were seven operational sea tours on which I either stood watch or supervised watch teams and monitored their performance. My nuclear naval engineering background, two tours in pre-commissioning CVNs, and service on two ships that represented the first ship of their class at that time, USS Arleigh Burke and USS Oscar Austin, qualifies me to write this paper. My experiences lead me to believe that there is room for improvement in the design phase of Navy ships to take human endurance and fatigue into consideration.

The goal of the analysis is to provide early discovery of system states from which the system will inevitably fail in the future by violating some formal specification. This goal can also be formulated as a form of temporal specification conflicts. The technique utilizes SAT-solver based bounded constraint solvingwithin a custom search algorithm. The proposed technique is also compared to an alternative model checking of Computational Tree Logic technique. The proposed technique can assist in providing an early warning for a mission critical system such as the power grid prior to an emerging catastrophic failure.

The dropsonde provides high-quality, high-vertical-resolution profiles of atmospheric pressure, temperature, relative humidity, wind speed, and direction from the aircraft flight level to the surface over oceans and remote areas. Since 1996, GPS dropsondes have been routinely dropped during hurricane reconnaissance and surveillance flights to help predict hurricane track and intensity. From 1996 to 2012, NOAA has dropped 13,681 dropsondes inside hurricane eye walls or in the surrounding environment for 120 tropical cyclones (TCs). All NOAA dropsonde data have been collected, reformatted to one format, and consistently and carefully quality controlled using state-of-the-art quality-control (QC) tools. Three value-added products, the vertical air velocity and the radius and azimuth angle of each dropsonde location, are generated and added to the dataset. As a result, a long-term (1996-2012), high-quality, high-vertical-resolution (similar to 5-15 m) GPS dropsonde dataset is created and made readily available for public access. The dropsonde data collected during hurricane reconnaissance and surveillance flights have improved TC-track and TC-intensity forecasts significantly. The impact of dropsonde data on hurricane studies is summarized. The scientific applications of this long-term dropsonde dataset are highlighted, including characterizing TC structures, studying TC environmental interactions, identifying surface-based ducts in the hurricane environment that affect electromagnetic wave propagation, and validating satellite temperature and humidity profiling products.

These two-dimensional oblique impact predictions are often used for studies of wave slam loadings, as well as observations of the asymmetric formation of the spray jets. In the present study, an existing zero gravity, inviscid two-dimensional oblique impact model is applied to the three-dimensional planing case using slender body theory, producing estimates of planing hull side force as a function of yaw angle. Plots are generated to predict the side force generated by planing surfaces as a function of speed, beam, wetted length, trim angle and yaw angle. The resulting predictions are compared with previously published and new measurements of planing hull side forces during steady drift tests. The comparisons are used to establish recommended limitations of the method and provide insight into future work. Published by Elsevier Ltd.

A double-layered absorber consisting of a 32-nm-thick aluminum (Al) metallic layer, located on a glass medium (Si02) of 1 mm thickness, was fabricated and used to design a fine-tuned absorber through a theoretical and finite element modeling process. The results indicate that the proposed low-cost, double-layered absorber can be tuned based on the metal layer sheet resistance and the thickness of various glass media. This can be done in a way that takes advantage of the diversity of the absorption of the metal films in the desired THz domain (6 to 10 THz). It was found that the composite absorber could absorb up to 86% (a percentage exceeding the 50%, previously shown to be the highest achievable when using single thin metal layer) and reflect <1% of the incident THz power. This approach will enable monitoring of the transmission coefficient (THz transmission fingerprint) of the biosample with high accuracy, while also making the proposed double-layered absorber a good candidate for a microbolometer pixel's active element.

CA MAGIC Collaboration VERITAS Collaboration TI Unprecedented study of the broadband emission of Mrk 421 during flaring activity in March 2010 SO ASTRONOMY & ASTROPHYSICS LA English DT Article DE radiation mechanisms: non-thermal; galaxies: active; BL Lacertae objects: individual: Mrk 421; gamma rays: galaxies ID LARGE-AREA TELESCOPE; BL LACERTAE OBJECTS; GAMMA-RAY OUTBURST; SIMULTANEOUS MULTIWAVELENGTH OBSERVATIONS; ATMOSPHERIC CHERENKOV TELESCOPES; EXTRAGALACTIC BACKGROUND LIGHT; SPECTRAL ENERGY-DISTRIBUTION; SELF-COMPTON MODEL; X-RAY; TEV BLAZARS AB Context. Because of its proximity, Mrk 421 is one of the best sources on which to study the nature of BL Lac objects. Its proximity allows us to characterize its broadband spectral energy distribution (SED). Aims. The goal is to better understand the mechanisms responsible for the broadband emission and the temporal evolution of Mrk 421. These mechanisms may also apply to more distant blazars that cannot be studied with the same level of detail. Methods. A flare occurring in March 2010 was observed for 13 consecutive days (from MJD 55 265 to MJD 55 277) with unprecedented wavelength coverage from radio to very high energy (VHE; E > 100 GeV) gamma-rays with MAGIC, VERITAS, Whipple, Fermi-LAT, MAXI, RXTE, Swift, GASP-WEBT, and several optical and radio telescopes. We modeled the day-scale SEDs with one-zone and two-zone synchrotron self-Compton (SSC) models, investigated the physical parameters, and evaluated whether the observed broadband SED variability can be associated with variations in the relativistic particle population. Results. The activity of Mrk 421 initially was high and then slowly decreased during the 13-day period. The flux variability was remarkable at the X-ray and VHE bands, but it was minor or not significant at the other bands. The variability in optical polarization was also minor. These observations revealed an almost linear correlation between the X-ray flux at the 2-10 keV band and the VHE gamma-ray flux above 200 GeV, consistent with the gamma-rays being produced by inverse-Compton scattering in the Klein-Nishina regime in the framework of SSC models. The one-zone SSC model can describe the SED of each day for the 13 consecutive days reasonably well, which once more shows the success of this standard theoretical scenario to describe the SEDs of VHE BL Lacs such as Mrk 421. This flaring activity is also very well described by a two-zone SSC model, where one zone is responsible for the quiescent emission, while the other smaller zone, which is spatially separated from the first, contributes to the daily variable emission occurring at X-rays and VHE gamma-rays. The second blob is assumed to have a smaller volume and a narrow electron energy distribution with 3 x 10(4) < gamma < 6 x 10(5), where. is the Lorentz factor of the electrons. Such a two-zone scenario would naturally lead to the correlated variability at the X-ray and VHE bands without variability at the optical/UV band, as well as to shorter timescales for the variability at the X-ray and VHE bands with respect to the variability at the other bands. Conclusions. Both the one-zone and the two-zone SSC models can describe the daily SEDs via the variation of only four or five model parameters, under the hypothesis that the variability is associated mostly with the underlying particle population. This shows that the particle acceleration and cooling mechanism that produces the radiating particles might be the main mechanism responsible for the broadband SED variations during the flaring episodes in blazars. The two-zone SSC model provides a better agreement with the observed SED at the narrow peaks of the low-and high-energy bumps during the highest activity, although the reported one-zone SSC model could be further improved by varying the parameters related to the emitting region itself (delta, B and R), in addition to the parameters related to the particle population.

In particular, these material properties have been exploited to significantly enhance the transduction of biorecognition events in fluorescence-based biosensing involving Forster resonant energy transfer (FRET). This review analyzes current advances in sensors and biosensors that utilize graphene, CNTs or CDs as the platform in optical sensors and biosensors. Widely utilized synthesis/fabrication techniques, intrinsic material properties and current research examples of such nanocarbon, FRET-based sensors/biosensors are illustrated. The future outlook and challenges for the research field are also detailed.

TI Bilocal current densities and mean trajectories in a Young interferometer with two Gaussian slits and two detectors SO JOURNAL OF MATHEMATICAL PHYSICS LA English DT Article ID DELAYED-CHOICE EXPERIMENT AB The recent single-photon double-slit experiment of Steinberg et al., based on a weak measurement method proposed by Wiseman, showed that, by encoding the photon's transverse momentum behind the slits into its polarization state, the momentum profile can subsequently be measured on average, from a difference of the separated fringe intensities for the two circular polarization components. They then integrated the measured average velocity field, to obtain the average trajectories of the photons enroute to the detector array. In this paper, we propose a modification of their experiment, to demonstrate that the average particle velocities and trajectories change when the mode of detection changes. The proposed experiment replaces a single detector by a pair of detectors with a given spacing between them. The pair of detectors is configured so that it is impossible to distinguish which detector received the particle. The pair of detectors is then analogous to the simple pair of slits, in that it is impossible to distinguish which slit the particle passed through. To establish the paradoxical outcome of the modified experiment, the theory and explicit three-dimensional formulas are developed for the bilocal probability and current densities, and for the average velocity field and trajectories as the particle wavefunction propagates in the volume of space behind the Gaussian slits. Examples of these predicted results are plotted. Implementation details of the proposed experiment are discussed. (c) 2015 AIP Publishing LLC. C1 [Withers, L.

A BVA dilution oil was used for the control. Oil-based adulticides were sprayed using a truck-mounted Curtis DynaFog Maxi-Pro 4 ultra-low volume (ULV) sprayer. Malathion (Fyfanon ULV, 96% active ingredient [AI]), resmethrin (Scourge 4 + 12, 4% AI), pyrethrins (ULD BP-300, 3% AI), and BVA Spray 13 (100% refined petroleum distillate) were mixed with Uvitex optical brightener fluorescent dye and applied at 2 speeds on evenings when wind speed was less than 16.1 km/h (10 mph). Collection targets using biodegradable cotton ribbons (I m x 2.5 cm) were later read with a fluorometer to quantify the amount of insecticide deposited on targets set at heights of 15.2, 76.2, and 152.4 cm (6, 30, and 60 in.) and distances of 1.5, 6.1, 15.2, 30.5, 61.0, and 91.4 m (5, 20, 50, 100, 200, and 300 ft). Mean insecticide deposition across all distances was 31% on 76.2-cm targets and 49% on 152.4-cm targets, while 15.2-cm targets typically collected <20% of test spray. Mean ground temperatures were typically within 5 degrees C of air temperatures at 152.4 cm and within 1 to 5 degrees C of air at 15.2 cm or 76.2 cm. Collectively, mean insecticide deposition was 80% at or above 76.2 cm for all insecticides. This finding may explain in part why control of low-flying phlebotomine sand flies with ULV insecticides has been met with less than optimal success by US military forces deployed in the Middle East.

Two battery-powered sprayers, Birchmeier and Hudson, were coriwared with the standard hand-pump SOLO 425 sprayer, which is currently used in pest management operations. Physical characteristics, droplet analysis, and overall ease of use were documented. Multiple dilutions of the insecticide were also evaluated. The results indicated that the Birchmeier sprayer was the preferable machine in terms of its physical characteristics and operator use. There was no significant difference in percent mortality of the test mosquitoes between the sprayers. Multiple dilutions ranging from 1:9 to 1:1050 of the insecticide resulted in greater than 80% mean mortality.

These are applied to a study of transport and mixing in the Hill's spherical vortex subject to a linear strain rate field. We consider the axisymmetric case and the fully three dimensional case with different types of time dependence. We develop a Lagrangian characterization of transport and mixing appropriate for open three dimensional flows and we show that the EIs provide a detailed description of the flow structure that can be correlated with the Lagrangian transport and mixing results. The EIs yield results consistent with the dynamics of the Hill's vortex flow characteristics, correlation with transverse shear, and anti-correlation with transversality. (C) 2015 AIP Publishing LLC.

The motion results in X-ray emission, but the brilliance and photon energy are limited by the electrons' initial transverse coordinate. To overcome this, we exploit parametrically unstable betatron motion in a cavitated, axially modulated plasma. Theory and simulations are presented showing that the unstable oscillations increase both the total X-ray energy and average photon energy. C1 [Palastro, J.

On mineral surfaces such as calcite, biomolecular recognition of, and self-assembly on, distinct atomic kinks and steps could additionally orchestrate changes to the overall shape and symmetry of a bulk crystal. In this work, we show through in situ atomic force microscopy (AFM) experiments that an acidic 20 kDa cement protein from the barnacle Megabalanus rosa (MRCP20) binds specifically to step edge atoms on {10 (1) over bar4} calcite surfaces, remains bound and further assembles over time to form one-dimensional nanofibrils. Protein nanofibrils are continuous and organized at the nanoscale, exhibiting striations with a period of ca. 45 nm. These fibrils, templated by surface steps of a preferred geometry, in turn selectively dissolve underlying calcite features displaying the same atomic arrangement. To demonstrate this, we expose the protein solution to bare and fibril-associated rhombohedral etch pits to reveal that nanofibrils accelerate only the movement of fibril-forming steps when compared to undecorated steps exposed to the same solution conditions. Calcite mineralized in the presence of MRCP20 results in asymmetric crystals defined by frustrated faces with shared mirror symmetry, suggesting a similar step-selective behavior by MRCP20 in crystal growth. As shown here, selective surface interactions with step edge atoms lead to a cooperative regime of calcite modification, where templated long-range protein nanostructures shape crystals.

TI Optical Dark-Field and Electron Energy Loss Imaging and Spectroscopy of Symmetry-Forbidden Modes in Loaded Nanogap Antennas SO ACS NANO LA English DT Article DE localized surface plasmon; hybrid nanoparticles; plasmon hybridization; dark-field spectroscopy; electron energy loss spectroscopy; nanogap antenna ID LOCALIZED PLASMON RESONANCES; GOLD NANORODS; NANOPARTICLE; NANOANTENNAS; DIMERS; INTERFERENCE; ENHANCEMENT; MECHANISMS; SCATTERING; NANOWIRES AB We have produced large numbers of hybrid metal semiconductor nanogap antennas using a scalable electrochemical approach and systematically characterized the spectral and spatial character of their plasmonic modes with optical dark-field scattering, electron energy loss spectroscopy with principal component analysis, and full wave simulations. The coordination of these techniques reveal that these nanostructures support degenerate transverse modes which split due to substrate interactions, a longitudinal mode which scales with antenna length, and a symmetry-forbidden gap-localized transverse mode. This gap-localized transverse mode arises from mode splitting of transverse resonances supported on both antenna arms and is confined to the gap load enabling (i) delivery of substantial energy to the gap material and (ii) the possibility of tuning the antenna resonance via active modulation of the gap material's optical properties. The resonant position of this symmetry-forbidden mode is sensitive to gap size, dielectric strength of the gap material, and is highly suppressed in air-gapped structures which may explain its absence from the literature to date. Understanding the complex modal structure supported on hybrid nanosystems is necessary to enable the multifunctional components many seek.

TI FERMI LARGE AREA TELESCOPE THIRD SOURCE CATALOG SO ASTROPHYSICAL JOURNAL SUPPLEMENT SERIES LA English DT Article DE catalogs; gamma-rays: general ID GAMMA-RAY EMISSION; PULSAR WIND NEBULA; ALL-SKY SURVEY; ACTIVE GALACTIC NUCLEI; PSR B1259-63/LS 2883; SUPERNOVA REMNANT; RADIO-SOURCES; UNASSOCIATED SOURCES; GLOBULAR-CLUSTERS; WMAP OBSERVATIONS AB We present the third Fermi Large Area Telescope (LAT) source catalog (3FGL) of sources in the 100 MeV-300 GeV range. Based on the first 4 yr of science data from the Fermi Gamma-ray Space Telescope mission, it is the deepest yet in this energy range. Relative to the Second Fermi LAT catalog, the 3FGL catalog incorporates twice as much data, as well as a number of analysis improvements, including improved calibrations at the event reconstruction level, an updated model for Galactic diffuse.-ray emission, a refined procedure for source detection, and improved methods for associating LAT sources with potential counterparts at other wavelengths. The 3FGL catalog includes 3033 sources above 4 sigma significance, with source location regions, spectral properties, and monthly light curves for each. Of these, 78 are flagged as potentially being due to imperfections in the model for Galactic diffuse emission. Twenty-five sources are modeled explicitly as spatially extended, and overall 238 sources are considered as identified based on angular extent or correlated variability (periodic or otherwise) observed at other wavelengths. For 1010 sources we have not found plausible counterparts at other wavelengths. More than 1100 of the identified or associated sources are active galaxies of the blazar class; several other classes of non-blazar active galaxies are also represented in the 3FGL. Pulsars represent the largest Galactic source class. From source counts of Galactic sources we estimate that the contribution of unresolved sources to the Galactic diffuse emission is similar to 3% at 1 GeV. C1 [Acero, F.; Ballet, J.; Casandjian, J.

Here we report that hyperbolic phonon polaritons allow for a flat slab of hexagonal boron nitride to enable exciting near-field optical applications, including unusual imaging phenomenon (such as an enlarged reconstruction of investigated objects) and sub-diffractional focusing. Both the enlarged imaging and the super-resolution focusing are explained based on the volume-confined, wavelength dependent propagation angle of hyperbolic phonon polaritons. With advanced infrared nanoimaging techniques and state-of-art mid-infrared laser sources, we have succeeded in demonstrating and visualizing these unexpected phenomena in both Type I and Type II hyperbolic conditions, with both occurring naturally within hexagonal boron nitride. These efforts have provided a full and intuitive physical picture for the understanding of the role of hyperbolic phonon polaritons in near-field optical imaging, guiding, and focusing applications.

TI ON THE MERGING CLUSTER ABELL 578 AND ITS CENTRAL RADIO GALAXY 4C+67.13 SO ASTROPHYSICAL JOURNAL LA English DT Article DE galaxies: active; galaxies: clusters: individual (Abell 578); galaxies: individual (4C+67.13); galaxies: jets; intergalactic medium; X-rays: galaxies: clusters ID DEEP CHANDRA OBSERVATION; ACTIVE GALACTIC NUCLEI; DIGITAL SKY SURVEY; SUPERMASSIVE BLACK-HOLES; CENTIMETER VLA SURVEY; BRIGHTEST CLUSTER; XMM-NEWTON; JET POWER; ACCRETION MODES; HOST GALAXIES AB Here we analyze radio, optical, and X-ray data for the peculiar cluster Abell 578. This cluster is not fully relaxed and consists of two merging sub-systems. The brightest cluster galaxy (BCG), CGPG 0719.8+6704, is a pair of interacting ellipticals with projected separation similar to 10 kpc, the brighter of which hosts the radio source 4C+67.13. The Fanaroff-Riley type-II radio morphology of 4C+67.13 is unusual for central radio galaxies in local Abell clusters. Our new optical spectroscopy revealed that both nuclei of the CGPG 0719.8+6704 pair are active, albeit at low accretion rates corresponding to the Eddington ratio similar to 10(-4) (for the estimated black hole masses of similar to 3x10(8) M-circle dot and similar to 10(9) M.). The gathered X-ray (Chandra) data allowed us to confirm and to quantify robustly the previously noted elongation of the gaseous atmosphere in the dominant sub-cluster, as well as a large spatial offset (similar to 60 kpc projected) between the position of the BCG and the cluster center inferred from the modeling of the X-ray surface brightness distribution. Detailed analysis of the brightness profiles and temperature revealed also that the cluster gas in the vicinity of 4C+67.13 is compressed (by a factor of about similar to 1.4) and heated (from similar or equal to 2.0 keV up to 2.7 keV), consistent with the presence of a weak shock (Mach number similar to 1.3) driven by the expanding jet cocoon. This would then require the jet kinetic power of the order of similar to 10(45) erg s(-1), implying either a very high efficiency of the jet production for the current accretion rate, or a highly modulated jet/accretion activity in the system.

SO ASTROPHYSICAL JOURNAL LA English DT Article DE acceleration of particles; cosmic rays; ISM: supernova remnants; magnetic fields; shock waves ID SUPERNOVA REMNANT SHOCKS; COSMIC-RAY PRECURSOR; PARTICLE-ACCELERATION; HYDROMAGNETIC-WAVES; MAGNETIC-FIELD; INSTABILITY; TURBULENCE; SPECTRUM; AMPLIFICATION; TRANSMISSION AB We describe a new model for the "stripes" of synchrotron radiation seen in the remnant of Tycho's supernova. In our picture, cosmic rays streaming ahead of the forward shock generate parallel propagating (with respect to the local magnetic field direction) circularly polarized Alfven waves that are almost free of dissipation, and, due to being circularly polarized, exhibit no spatial variation of magnetic field strength. Following the interaction with the supernova remnant (SNR) shock with nonzero obliquity, these parallel propagating waves become obliquely propagating, due the the wave refraction (which is different, in principle, for the different plane wave components), and dissipation sets in. The magnetosonic polarization decays faster, due to transit time damping, leaving only the Alfven mode. This surviving mode now exhibits a spatial variation of the magnetic field, leading to local maxima and minima in the synchrotron emission, i.e., the stripes. We attribute the initial wave generation to the Bell instability, which in contrast to the resonant generation of upstream Alfven waves, gives rise to a preferred wavelength, and hence the single wave period at which the stripes are seen. Based on estimates for damping rates due to turbulent cascade and transit time damping, we estimate the dependence of the visibility of the stripes on the shock obliquity and determine a maximum cosmic ray energy in Tycho's SNR in the range 6x10(14)-1x10(15) eV.

TI ASYMMETRIC MAGNETIC RECONNECTION IN WEAKLY IONIZED CHROMOSPHERIC PLASMAS SO ASTROPHYSICAL JOURNAL LA English DT Article DE magnetic reconnection; methods: numerical; plasmas; Sun: chromosphere ID 2-FLUID SIMULATIONS; SOLAR CHROMOSPHERE; PENUMBRAL MICROJETS; AMBIPOLAR DIFFUSION; ELLERMAN BOMBS; CURRENT LOOPS; IONIZATION; ATMOSPHERE; DRIVEN; FLARE AB Realistic models of magnetic reconnection in the solar chromosphere must take into account that the plasma is partially ionized and that plasma conditions within any two magnetic flux bundles undergoing reconnection may not be the same. Asymmetric reconnection in the chromosphere may occur when newly emerged flux interacts with pre-existing, overlying flux. We present 2.5D simulations of asymmetric reconnection in weakly ionized, reacting plasmas where the magnetic field strengths, ion and neutral densities, and temperatures are different in each upstream region. The plasma and neutral components are evolved separately to allow non-equilibrium ionization. As in previous simulations of chromospheric reconnection, the current sheet thins to the scale of the neutral-ion mean free path and the ion and neutral outflows are strongly coupled. However, the ion and neutral inflows are asymmetrically decoupled. In cases with magnetic asymmetry, a net flow of neutrals through the current sheet from the weak-field (high-density) upstream region into the strong-field upstream region results from a neutral pressure gradient. Consequently, neutrals dragged along with the outflow are more likely to originate from the weak-field region. The Hall effect leads to the development of a characteristic quadrupole magnetic field modified by asymmetry, but the X-point geometry expected during Hall reconnection does not occur. All simulations show the development of plasmoids after an initial laminar phase. C1 [Murphy, Nicholas A.] Harvard Smithsonian Ctr Astrophys, Cambridge, MA 02138 USA.

TI A VERY DEEP CHANDRA OBSERVATION OF THE GALAXY GROUP NGC 5813: AGN SHOCKS, FEEDBACK, AND OUTBURST HISTORY SO ASTROPHYSICAL JOURNAL LA English DT Article DE galaxies: active; galaxies: clusters: general; galaxies: groups: individual (NGC 5813); galaxies: individual (NGC 5813); X-rays: galaxies ID X-RAY SPECTROSCOPY; GALACTIC NUCLEUS FEEDBACK; ELLIPTIC GALAXIES; PERSEUS CLUSTER; GAS MOTIONS; HIGH-RESOLUTION; COOLING FLOW; COLD FRONTS; INTRACLUSTER MEDIUM; RADIO-LOBE AB We present results from a very deep (650 ks) Chandra X-ray observation of the galaxy group NGC 5813, the deepest Chandra observation of a galaxy group to date. This system uniquely shows three pairs of collinear cavities, with each pair associated with an unambiguous active galactic nucleus (AGN) outburst shock front. The implied mean kinetic power is roughly the same for each outburst, demonstrating that the average AGN kinetic luminosity can remain stable over long timescales (similar to 50 Myr). The two older outbursts have larger, roughly equal total energies as compared with the youngest outburst, implying that the youngest outburst is ongoing. We find that the gas radiative cooling rate and mean shock heating rate are well balanced at each shock front, suggesting that shock heating alone is sufficient to offset cooling and establish AGN/intracluster medium (ICM) feedback within at least the central 30 kpc. This heating takes place roughly isotropically and most strongly at small radii, as is required for feedback to operate. We suggest that shock heating may play a significant role in AGN feedback at smaller radii in other systems, where weak shocks are more difficult to detect. We find non-zero shock front widths that are too large to be explained by particle diffusion. Instead, all measured widths are consistent with shock broadening due to propagation through a turbulent ICM with a mean turbulent speed of similar to 70 km s(-1). Finally, we place lower limits on the temperature of any volume-filling thermal gas within the cavities that would balance the internal cavity pressure with the external ICM. C1 [Randall, S.

TI Efficacy, but Not Antibody Titer or Affinity, of a Heroin Hapten Conjugate Vaccine Correlates with Increasing Hapten Densities on Tetanus Toxoid, but Not on CRM197 Carriers SO BIOCONJUGATE CHEMISTRY LA English DT Article ID SUBSTANCE-ABUSE; GLYCOCONJUGATE VACCINES; MORPHINE/HEROIN VACCINE; PROTEIN; TOXIN; RATS; 6-MONOACETYLMORPHINE; IMMUNOGENICITY; DERIVATIVES; ADDICTION AB Vaccines against drugs of abuse have induced antibodies in animals that blocked the biological effects of the drug by sequestering the drug in the blood and preventing it from crossing the blood-brain barrier. Drugs of abuse are too small to induce antibodies and, therefore, require conjugation of drug hapten analogs to a carrier protein. The efficacy of these conjugate vaccines depends on several factors including hapten design, coupling strategy, hapten density, carrier protein selection, and vaccine adjuvant. Previously, we have shown that 1 (MorHap), a heroin/morphine hapten, conjugated to tetanus toxoid (TT) and mixed with liposomes containing monophosphoryl lipid A [L(MPLA)] as adjuvant, partially blocked the antinociceptive effects of heroin in mice. Herein, we extended those findings, demonstrating greatly improved vaccine induced antinociceptive effects up to 3% mean maximal potential effect (%MPE). This was obtained by evaluating the effects of vaccine efficacy of hapten 1 vaccine conjugates with varying hapten densities using two different commonly used carrier proteins, TT and cross-reactive material 197 (CRM197). Immunization of mice with these conjugates mixed with L(MPLA) induced very high anti-1 IgG peak levels of 400-1500 mu g/mL that bound to both heroin and its metabolites, 6-acetylmorphine and morphine. Except for the lowest hapten density for each carrier, the antibody titers and affinity were independent of hapten density. The TT carrier based vaccines induced long-lived inhibition of heroin-induced antinociception that correlated with increasing hapten density. The best formulation contained TT with the highest hapten density of >= 30 haptens/TT molecule and induced %MPE of approximately 3% after heroin challenge. In contrast, the best formulation using CRM197 was with intermediate 1 densities (10-15 haptens/CRM197 molecule), but the % MPE was approximately 13%. In addition, the chemical synthesis of 1, the optimization of the conjugation method, and the methods for the accurate quantification of hapten density are described.

Analysis of the chemical composition of the ATJ showed a high quantity of two specific branched alkanes (2,2,4,4,6,8,8-heptamethylnonane and 2,2,4,6,6-pentamethylheptane) and a small quantity of other branched alkanes that are isomers of these two alkanes. Surrogate mixtures containing 2,2,4,4,6,8,8-heptamethylnonane and a mixture of isododecane isomers were prepared to determine what composition would match the density, viscosity, speed of sound, bulk modulus, surface tension, and flash point of ATJ. The optimal surrogate contained a 0.25 mass fraction of 2,2,4,4,6,8,8-heptamethylnonane in isododecane isomers. Combustion experiments were then conducted in a Yanmar diesel engine with fuel mixtures containing 70% (by volume) petroleum jet fuel with 30% ATJ, 2,2,4,4,6,8,8-heptamethylnonane, the optimal surrogate mixtures based on physical properties, or the isododecane isomers. The startup performances of the three 30% surrogate mixtures were very similar to that of the 70% JP-5 with 30% ATJ fuel. No significant differences were seen in the engine combustion characteristics of the three 70/30 surrogates, as compared to the base 70% JP-5/30% ATJ fuel mixture. These results show that a surrogate mixture has been successfully prepared that matches the physical and chemical properties and combustion behavior of an ATJ fuel. C1 [Prak, Dianne J.

Natural energy harvesting complexes have exquisite spectrally- and spatially-tuned systems with high redundancy to maximize their ability to gather, channel, and distribute electromagnetic radiation. Attempting to mimic these highly efficient systems requires at the very least (sub)nanoscale precision in the positioning of light sensitive molecules, the latter of which must also possess carefully selected photophysical properties; in essence, these two fundamental properties must be exploited in a synergistic manner. First, the scaffold must be highly organized, ideally with multiple symmetrical components that are spatially arranged with nanoscale accuracy. Second, the structure must be amenable to chemical modification in order to be (bio)functionalized with the desired light sensitive moieties which have expanded greatly to now include organic dyes, metal chelates, fluorescent proteins, dye-doped and noble metal nanoparticles, photoactive polymers, along with semiconductor quantum dots amongst others. Several families of biological scaffolding molecules offer strong potential to meet these stringent requirements. Recent advances in bionanotechnology have provided the ability to assemble diverse naturally derived scaffolds along with manipulating their properties and this is allowing us to understand the capabilities and limitations of such artificial light-harvesting antennae and devices. The range of scaffold or template materials that have been used varies from highly symmetrical virus capsids to self-assembled biomaterials including nucleic acids and small peptides as well as a range of hybrid inorganic-biological systems. This review surveys the burgeoning field of artificial light-harvesting and energy transfer complexes that utilize biological scaffolds from the perspective of what each has to offer for optimized energy transfer. We highlight each biological scaffold with prominent examples from the literature and discuss some of the benefits and liabilities of each approach. Cumulatively, the available data suggest that DNA is the most versatile biological material currently available, though it has challenges including precise dye placement and subsequent dye performance. We conclude by providing a perspective on how this field will progress in both the short and long term, with a focus on the transition to applications and devices. Published by Elsevier B.V.

TI Resistance Prediction on Submerged Axisymmetric Bodies Fitted with Turbulent Spot Inducers SO JOURNAL OF SHIP RESEARCH LA English DT Article DE resistance (general); model testing; hydrodynamics (general) ID BOUNDARY-LAYER; TRANSITION AB A method to predict bare hull ship resistance is presented in this article. Hull resistance is assumed to consist of friction drag and residual drag. The friction drag coefficient is represented by an equivalent flat plate coefficient multiplied by a form factor to incorporate effects of body geometry and boundary layer (BL) characteristics on drag. Theories of form factors including the effect of BL transition locations have been successfully derived. Form factors are shown to have a noticeable effect on body drag at high Reynolds numbers (Re) and a significant effect at model Re. Residual drag coefficient is obtained from model tests with application of scaling formulae to relate model scale residual drag coefficient to full scale drag coefficient. To address the issue of laminar flow on models in residual drag measurements, a new device termed a "turbulent spot inducer" is introduced in model tests. Finally, a new scaling formula to relate model scale residual drag coefficient to full scale residual drag coefficient with the flow on body surface partly laminar and partly turbulent is derived. It is shown that a traditional 1+K scaling method used in the marine industry is a special case of the newly derived residual drag scaling formula.

This study examines the co-construction of culture through the conversational actions of the participants. Utilizing the cultural triangle of the three Ps (product, practice and perspective) proposed by the American Council on the Teaching of Foreign Languages (ACTFL) for classroom learning (National Standards in Foreign Language Education Project, 2006), this study examines whether this framework is useful for uncovering cultural talk in natural settings among Korean speakers of Japanese and their interlocutors. Cultural talk in this study is identified by demonstrating where participants display orientations through their conversational actions to culture. The findings move beyond the classroom to see how the participants display cultural awareness in conversations about culture and how ACTFL's products, practices and perspectives are accomplished in talk.

A locally corrected Nystrom discretization of the magnetostatic volume integral equation is used to implement the stepped solver. Characterization of the stepped solver is performed using various magnetic material models which support hysteresis. Solver accuracy is validated using Team Workshop Problem 13, analytic results of a magnetic sphere with hysteresis, and against measured data for a hollow steel pipe.

Intrusions of the Kuroshio and strong mesoscale variability in the Luzon Strait can influence their generation and propagation. Here, the authors use eight moorings and two numerical models to investigate these relationships by quantifying the coherence of the diurnal and semidiurnal internal tides in the Luzon Strait. This study finds that the level of coherence of internal tide generation, energy, and energy flux is quite variable, depending on the specific location within the Luzon Strait. Large-scale spatial patterns in internal tide pressure and velocity exist across the region, shaped by the bathymetry, mean flow, and stratification. Internal tide coherence is lower (<30%) near large gradients in this pattern (predominantly along the eastern ridge), which are shifted by the variable Kuroshio and mesoscale fields. At other locations within the Luzon Strait, the internal tide is largely coherent (>80%), and simple calculations suggest that remote sources of internal tides could account for these small decreases in coherence. To the west of the Luzon Strait (away from the primary generation regions), the model suggests that diurnal internal tide energy is more coherent than semidiurnal.

A DBMP is created in optically pumped nanocrystals by dynamic polarization of dangling bond spins, (DBSs) at the nanocrystal surface during radiative recombination of the ground state "dark" exciton assisted by a spin-flip of the DBS. The formation of DBMPs suppresses the radiative recombination of the dark exciton and leads to a temperature-dependent Contribution to the Stokes shift of the photoluminescence. This model consistently explains the experimentally observed low-temperature photoluminescence features of nonmagnetic cdSe nano crystals as manifestation's of their spin-related magnetic properties.

The basic strategy is to incorporate nanoaluminum in the form of a micrometer scale particle containing a gas-generator, to enable easier processing, and potential benefits resulting from reduced sintering prior to combustion. The mesoparticles were made by electrospray and comprised aluminum nanoparticles (50 nm) and nitrocellulose to form micrometer scale particles. In this study, 80% solids loaded composite propellants (AP/HTPB based) were made with the addition of micrometer sized (2-3 mm) aluminum (10 wt-%), and compared directly to propellants made by directly substituting aluminum mesoparticles for traditional micrometer sized particles. Propellant burning rate was relatively insensitive for mesoparticles containing between 5-15 wt-% nitrocellulose. However, direct comparison between a mesoparticle based propellant, to a propellant containing micrometer scale aluminum particles showed burning rates approximately 35% higher while having a nearly identical burning rate exponent. High speed imaging indicate that propellants using mesoparticles have less agglomeration of particles on the propellant surface.

TI Effective Strategy for Improving Electrocatalyst Durability by Adhesive Immobilization of Catalyst Nanoparticles on Graphitic Carbon Supports SO ACS CATALYSIS LA English DT Article DE tantalum polyphosphate; nanoglue; anchoring; ORR; durability; nanoparticle ripening ID TRANSMISSION ELECTRON-MICROSCOPY; FUEL-CELL CATALYSTS; OXYGEN REDUCTION; ANCHORING SEMICONDUCTOR; TANTALUM OXYPHOSPHATE; METAL NANOPARTICLES; ACID-SOLUTION; PLATINUM; DEGRADATION; PT/C AB We have found that Ta-based additive films in our catalyst system act as adhesives, which improves electrocatalyst durability by immobilizing the catalyst Pt NPs on the graphitic Vulcan carbon support. Furthermore, we suggest that this can be a general design principle in producing higher-durability electrocatalysts on graphitic supports. By electrochemically probing the contributing roles of the tantalum oxide (Ta2O5) and the polyphosphate (PPA) components in separate samples, we show that these combine to produce the observed improvement in activity and durability of our best catalyst, the tantalum polyphosphate (TaOPO4)-treated sample. To control variables for a valid electrochemical comparison, such as dissimilar catalyst particle size distributions and variations in surface coverage, four new catalyst samples closely matched in every way were prepared: (1) Pt/VC, (2) Pt[PPA/VC], (3) Pt/[Ta2O5/VC], and (4) Pt[TaOPO4/VC]. We present HR-TEM/HAADF-STEM, EDS elemental mapping, PXRD, XPS, and electrochemical activity and durability evidence, showing that the TaOPO4 and Ta2O5 additives act as adhesives, effectively tethering the NPs to the VC graphitic support surface. Pt/[Ta2O5/VC] exhibited 3X better durability as compared with the Pt/VC control because of better catalyst nanoparticle immobilization by the Ta2O5 adhesive. Pt[TaOPO4/VC] is the overall best performer, exhibiting both a high MA of 0.82 A mg(pt)(-1), the highest ORR MA after heat treatment, as well as 1.75X greater durability over the Pt/VC control.

TI Structure of Chlamydomonas reinhardtii THB1, a group 1 truncated hemoglobin with a rare histidine-lysine heme ligation SO ACTA CRYSTALLOGRAPHICA SECTION F-STRUCTURAL BIOLOGY COMMUNICATIONS LA English DT Article DE 2/2 hemoglobin; distal ligand; nitric oxide dioxygenase; nitrogen metabolism; lysine coordination ID X-RAY-STRUCTURE; NITRIC-OXIDE; MYCOBACTERIUM-TUBERCULOSIS; LIGAND-BINDING; MONOMERIC HEMOGLOBIN; CYTOCHROME C-550; PROTEIN; GLOBINS; IDENTIFICATION; REVEALS AB THB1 is one of several group 1 truncated hemoglobins (TrHb1s) encoded in the genome of the unicellular green alga Chlamydomonas reinhardtii. THB1 expression is under the control of NIT2, the master regulator of nitrate assimilation, which also controls the expression of the only nitrate reductase in the cell, NIT1. In vitro and physiological evidence suggests that THB1 converts the nitric oxide generated by NIT1 into nitrate. To aid in the elucidation of the function and mechanism of THB1, the structure of the protein was solved in the ferric state. THB1 resembles other TrHb1s, but also exhibits distinct features associated with the coordination of the heme iron by a histidine (proximal) and a lysine (distal). The new structure illustrates the versatility of the TrHb1 fold, suggests factors that stabilize the axial ligation of a lysine, and highlights the difficulty of predicting the identity of the distal ligand, if any, in this group of proteins.

The sensitivity gained from the arrayed configuration was found to depend on the ferromagnetic domain geometry of the films. Under small, externally applied fields, films with planar anisotropy yielded an optical modulation depth which increased linearly with the number of crystals in the array. In films with perpendicular anisotropy, linearity and sensitivity were obstructed by a mechanism of optical polarization incoherence which was found to be generated within the magnetic domains. Our results indicate that optimal sensitivity in arrayed configurations requires planar anisotropies, or a direction of laser propagation that is perpendicular to the local domain magnetization.

TI Visible Plasma Clouds With an Externally Excited Spherical Porous Cavity Resonator SO IEEE TRANSACTIONS ON PLASMA SCIENCE LA English DT Article DE Microwave breakdown; plasma devices; plasma generators ID WAVE AB A microwave driven resonator is as an electron/ion cloud generator for illumination and plasma source applications. A sustained porous cavity resonator (PCR) glow discharge is externally excited using a resonant frequency electromagnetic (EM) wave that excites large internal electric fields. The resonator with a Q of 300 amplifies the incident electric field by factors of about 100 causing a breakdown of the neutral gas inside the sphere. The rise time of the fields inside the sphere is Q times the wave period. A glowing plasma ball is sustained around the point where the maximum electric fields exceed the plasma-discharge threshold for the low-pressure gas inside the resonator. After the EM pump field is removed, the plasma light source is rapidly quenched. The externally driven spherical PCR was fabricated from a theoretical design of the PCR for a laboratory demonstration of the plasma ball generation system. Using both theory and experiment, basic research has been applied to understand: 1) the EMs of resonator excitation and amplification; 2) the generation of light by glow radio frequency discharge; and 3) the effect of background neutral density of the size and intensity of the glowing plasma clouds. For this study, plasma resonators were constructed for the spherical TM101 and TE101 modes and a TE011 circular-cylindrical cavity. All PCR structures provide the ability to confine a plasma into a desired spatial shape without magnetic fields.

That is why we performed experiments with RAFIRA operated in multishot mode (firing rate of 50 Hz), using different rail materials (CuCr and Dural) and various shot energies. For these experiments, the shot energy for RAFIRA was raised, for the first time, up to the maximum energy at a disposal of 1.45 MJ per shot with projectile masses of over 120 g. In this way, we were able to show that the influence of the rail material depends on the applied shot energy: for low shot energies (< 1 MJ), CuCr rails show better results in terms of velocities and exit times of the projectiles. This effect vanishes for high shot energies (> 1 MJ). Whereas in terms of electrical contact, Dural rails show both less erosion and the capability to maintain a solid sliding contact until shot out for all energies applied.

In this paper, the strain and strain-induced electric field associated with the longitudinal acoustic waves propagating in the xz plane of ferroelectric BaTiO3 crystal is applied to the perturbation theory of the acousto-optic interactions to examine the effect of the photoelastic tensor stiffening by z-directed acoustic-wave-induced electric fields on the effective photoelastic constant as extra control of optic wave interaction with x-directed acoustic waves in the crystal. The tensorial photoelastic coupling is suggested to have a great potential for development of low voltage and tunable acousto-optic devices by using the strain-induced electric field and tuning the strain magnitude.

When a particulate-contaminated surface is illuminated by high-power continuous-wave laser light, a short burst of light is emitted from the surface, and the particles rapidly heat over a period of milliseconds to thousands of degrees Celsius, migrating over and evaporating from the surface. The surviving particles tend to coalesce into larger ones and leave a relatively flat residue on the surface. The total volume of the material on the surface has decreased dramatically. The optical surface itself heats substantially during illumination, but the surface temperature can decrease as the material is evaporated. Optical surfaces that survive this process without catastrophic damage are found to be more resistant to laser damage than surfaces that have not undergone the process. The surface temperature of the conditioned surfaces under illumination is lower than that of unconditioned surfaces. These conditioning effects on particles occurred within the first 30 s of laser exposure, with subsequent laser shots not affecting particle distributions. High-speed photography showed the actual removal and agglomeration of individual particles to occur within about 0.7 ms. Elemental changes were measured using time-of-flight secondary ion mass spectroscopy, with conditioned residuals being higher in hydrocarbon content than pristine particles. The tests in this study were conducted on high-reflectivity distributed Bragg reflector coated optics with carbon microparticles in the size range of 20-50 mu m, gold particles of size 250 nm, and silica 1 mu m in size.

The objective was to study the dynamic behaviour of the fish cage model in waves and current. The fish cage model was composed of a model net, a flexible floating collar of the circular plastic type and a weight system. It was found that there are many wave periods in which cancellation of the wave-induced forces on the model occur. These cancellation wave periods are within the range of dimensioning wave periods commonly used for testing of fish farm structures and hence are important to be aware of. Large deformations of the net under realistic wave and current conditions were observed, where contact between the net and other parts of the structure were identified. This may cause damages to the net due to abrasion. C1 [Kristiansen, David; Lader, Pal; Jensen, Osten] SINTEF Fisheries & Aquaculture, N-7465 Trondheim, Norway.

It had two main parts: firstly the growth characteristics of E. larynx were investigated by use of field tests at a Norwegian aquaculture site; secondly the hydrodynamic drag on the fouled twines was studied in a towing tank by using fabricated models of net twines with artificial hydroid fouling. In the field tests, the growth of the hydroids was first measured after three weeks of immersion and then again after six weeks. During this interval, the density of hydroids and the thickness of the hydroid stem were almost constant (1.4 hydroids/mm and 0.29 mm, respectively), while the average length of the hydroids increased from 6.4 to 11.2 mm. The hydroid length followed a Rayleigh distribution, while the thickness was normal (Gaussian) distributed. Replicas of twines with three different levels of hydroid growth were made (1.5 hydroids/mm twine, hydroid length 9 mm, 16 mm and 20 mm), and the drag on these twines was measured at different towing velocities (0.1 to 1.4 m/s) and with different twine configurations. For the twine with the shortest hydroids (9 mm), the drag was from 1.5 times (Re=4000) to 2.2 times (Re=1000) the drag on a clean twine. For the longest hydroids (21 mm), the drag was 2 times and 3.8 times, respectively.

The oropharynx is most commonly affected. Angioedema of the small bowel is a much rarer occurrence; it uniformly presents with abdominal pain of variable duration. Case Report: A 51-year-old man presented to the emergency department (ED) with generalized abdominal pain, emesis, diarrhea, and bloating. Medical history was significant for hypertension and medications included captopril, metoprolol and aspirin. Vital signs and laboratory tests were unremarkable. Due to the presence of significant abdominal tenderness with guarding on examination, a FAST (focused assessment with ultrasound in trauma) examination was performed and revealed free fluid in the abdomen. A computed tomography scan of the abdomen was quickly obtained, which revealed a large amount of simple-appearing free fluid within the abdomen and mucosal edema throughout the small bowel. The patient underwent an emergent diagnostic laparoscopy and was ultimately diagnosed with angioedema of the small bowel, deemed secondary to captopril usage. Captopril was discontinued and symptoms gradually resolved with supportive care. When imaging is obtained in cases such as this one, small bowel submucosal edema and ascites are often present. Supportive care and cessation of ACEi usage are the cornerstones of treatment. Why Should an Emergency Physician Be Aware of This?: In patients on ACEi, it is important to keep this diagnosis in mind to potentially avoid an unneeded surgical intervention, as the condition is self-limiting and can be treated primarily with supportive measures.

TI The e-POP Radio Receiver Instrument on CASSIOPE SO SPACE SCIENCE REVIEWS LA English DT Review DE Ionosphere; Electric fields; Wave propagation; Digital receiver; Signal processing ID SPACE AB The Radio Receiver Instrument (RRI) is a four-channel digital receiver fed by four 3-metre monopoles, arranged in a crossed configuration, each connected to a high input impedance preamplifier. The RRI bandwidth extends from 10 Hz to 18 MHz. The receiver measures the electric fields of either spontaneous radio emissions or waves created by ground transmitters, such as ionosondes, high-frequency radars and ionospheric heaters. In order to measure accurately the intensity, frequency, direction of propagation and signal delay of such fields over the broad frequency range, modern digital receiver technology is employed. The amplified signals from the monopoles are digitized at a rate of 40 megasamples per second, and from there on, the signal is down-converted, filtered, time-stamped and communicated in digital form. The characterization results of the RRI flight model are reported. Formats for data commands for configuring the digital receiver and for data output are described. C1 [James, H. G.; King, E.

CERTO signals can be used to measure ionospheric Total Electron Content (TEC) and radio scintillations along propagation paths between CERTO and receivers. The combination of CERTO and the array of e-POP in-situ diagnostics form a powerful tool for studying ionospheric plasma processes that have not been previously possible. Of note, the combination CERTO and the Radio Receiver Instrument (RRI), a modern digital receiver, which measures between 10 Hz to 18 MHz in selectable bands allows for innovative High Frequency (HF) radio propagation experiments. The use of high-power HF ionospheric heating facilities for such experiments further allows for repeatable studies of a number of important plasma processes. The new CERTO beacon transmits un-modulated, phase-coherent waves at 150, 400, and 1067 MHz with either right-hand-circular or linear polarization and TEC is measured using either differential phase and/or Faraday rotation. With a linear array of CERTO receivers, TEC data can be used for tomographic imaging of the ionosphere yielding two-dimensional maps of the plasma below the satellite orbit. In addition, the three CERTO frequencies cover a wide range for determination of radio scintillation effects caused by diffraction from propagation through ionospheric irregularities. We will describe the CERTO beacon and several potential innovative experiments using HF heating facilities in conjunction with CERTO, the RRI and other e-POP instruments.
