AB The dielectric permittivity and electric breakdown strength of nanocomposites comprising poly(vinylidene fluoride-co-hexafluoro propylene) and phosphoric acid surface-modified BaTiO3 nanoparticles have been investigated as a function of the volume fraction of nanoparticles. The mode of binding of pentafluorobenzylphosphonic acid on the BaTiO3 particles was investigated using infrared and P-31 solid-state nuclear magnetic resonance spectroscopy, and the phosphonic acid was found to form well ordered, tightly bound monolayers. The effective permittivity of nanocomposites with low volume fractions (<50%) was in good agreement with standard theoretical models, with a maximum relative permittivity of 35. However, for nanoparticle volume fractions of greater than 50%, the effective permittivity was observed to decrease with increasing nanoparticle volume fraction, and this was correlated with an increase in porosity of the spin-coated nanocomposite films. The dielectric breakdown strength was also found to decrease with increasing volume fraction of the BaTiO3 nanoparticles, with an abrupt decrease observed around 10% and a gradual decrease for volume fractions of 20-50%. Comparison of these results with model calculations, using statistical particle packing simulations and effective medium theory for the permittivity and breakdown strength, indicates the important roles of nanoparticle percolation and porosity of the nanocomposites on the dielectric properties. The measured energy density at a field strength of 164 V/mu m, well below the breakdown strength, increased to a value of 3.2 J/cm(3) as the nanoparticle volume fraction is increased to 50%, roughly in line with the trend of the permittivity. The calculated maximum energy densities indicate maximal extractable energy (7-8 J/cm(3) at 1 kHz) for two different particle volume fractions, as a result of the interplay of the dependencies of permittivity and breakdown strength on volume fraction.

AB The parameterization of friction velocity, roughness length, and the drag coefficient over coastal zones and open water surfaces enables us to better understand the physical processes of air-water interaction. In context of measurements from the Humidity Exchange over the Sea Main Experiment (HEXMAX), we recently proposed wave-parameter dependent approaches to sea surface friction velocity and the aerodynamic roughness by using the dimensional analysis method. To extend the application of these approaches to a range of natural surface conditions, the present study is to assess this approach by using both coastal shallow (RASEX) and open water surface measurements (Lake Ontario and Grand Banks ERS-1 SAR) where wind speeds were greater than 6.44 m s(-1). Friction velocities, the surface aerodynamic roughness, and the neutral drag coefficient estimated by these approaches under moderate wind conditions were compared with the measurements mentioned above. Results showed that the coefficients in these approaches for coastal shallow water surface differ from those for open water surfaces, and that the aerodynamic roughness length in terms of wave age or significant wave height should be treated differently for coastal shallow and open water surfaces.

AB A three-component decomposition is applied to global analysis data to show the existence of a beta gyre, which causes Tropical Cyclone (TC) to drift from a large-scale environmental steering current. Analyses from the Global Data Assimilation and Prediction System (GDAPS) of the Korea Meteorological Administration (KMA), the Global Forecast System (GFS) of NCEP, and the Navy Operational Global Atmospheric Prediction System (NOGAPS) are used in this study.
The structure of the beta gyre obtained in our analyses is in good agreement with the theoretical structure, with a cyclonic circulation to the southwest of the TC center, an anticyclonic circulation to the northeast, and a ventilation flow directed northwestward near the center. The circulation of the beta gyre is strongest at the 850-hPa level where the cyclonically swirling primary circulation is strongest, and decreases with height, in a pyramid shape similar to the primary circulation. The individual structure of the beta gyre is case- and model-dependent. At a certain analysis time, one model may clearly reveal a well-defined beta gyre, but the other models may not. Within one model, the beta gyre may be well defined at some analysis times, but not at other times. The structure of the beta gyre in the analysis field is determined by the nature of the vortex initialization scheme and the model behavior during the 6-h forecast in the operational data assimilation cycle.

AB Background: Nighttime activity, a common occurrence in persons with dementia, increases the risk for injury and unattended home exits and impairs the sleep patterns of caregivers. Technology is needed that will alert caregivers of nighttime activity in persons with dementia to help prevent injuries and unattended exits.
Methods: As part of a product development grant, a controlled pilot study was conducted to test the effectiveness of a new night monitoring system designed for informal caregivers to use in the home. Data from 53 subjects were collected at nine points in time during a 12-month period regarding injuries and unattended home exits that occurred while the caregiver slept. Nighttime activity frequently resulted in nursing home placement.
Results: The night monitoring system proved a reliable adjunct to assist caregivers in managing nighttime activity. A total of nine events (injuries or unattended home exits) occurred during the study, with 6 events occurring in the control group. With intent-to-treat analysis, there was no difference between the groups. However, in a secondary analysis that was based on use of the intervention, experimental subjects were 85% less likely to sustain an event than control subjects.
Conclusions: When nighttime activity occurred, it resulted in severe injuries sometimes associated with subsequent nursing home placement. The night monitoring system represents a new technology that caregivers can use to assist them in preventing nighttime injuries and unattended home exits in care recipients with dementia.

AB PURPOSE: There is significant public and veteran concerns over the impact of military deployments to Iraq and Afghanistan on veterans' health. This study investigates morbidity among deployers by uniquely comparing after-deployment hospitalizations to before-deployment hospitalizations and hospitalizations among nondeployers.
METHODS: To compare after,deployment with before-deployment rates of morbidity, we examined active-duty military personnel who deployed for the first time in support of the current conflicts in 2003 or 2004 and had at least 12 months of service before deployment. We also compared the after-deployment hospitalizations to hospitalizations of personnel serving on active duty from May 2002 through May 2004 without a deployment from September 2001 through August 2006. This historical prospective investigation utilized Cox's proportional hazards time-to,event modeling. Hospitalizations for any cause and hospitalizations based on 14 broad diagnostic categories were examined.
RESULTS: After adjusting for demographic and Occupational variables, the after-deployment risk for any-cause hospitalization was greater in comparison with before-deployment (hazard ratio, 1.57; 95% CI, 1.48-1.66) but lower in comparison with nondeployers (HR, 0.95, 95% CI, 0.92-0.98).
CONCLUSIONS: Active-duty service members have an increased risk of hospitalization after deployment compared with before deployment but a lower risk when compared with nondeployers. Ann Epidemiol 2009;19:603-612. (C) Published by Elsevier Inc.

AB PURPOSE: To describe medical symptom and condition reporting in relation to complementary and alternative medicine (CAM) use among members of the US military.
METHODS: CAM was defined as health treatments not widely taught at US medical schools or typically available at US hospitals. By using data from the Millennium Cohort Study, we included participants who completed a survey from 2004 to 2006 (n = 86,131) as part of this cross-sectional analysis in which we sought to identify demographic characteristics and types of health-related symptoms and conditions associated with CAM use. Chi-square tests were used to compare health assessed by self-reported symptoms and conditions among those not reporting CAM use with those reporting practitioner-assisted or self-administered CAM.
RESULTS: Of 86,131 participants, 30% reported using at least one practitioner-assisted CAM therapy, 27% reported using at least one self-administered CAM therapy, whereas 59% did not report using any CAM therapy. Both women and men who used CAM reported a greater proportion of specific health conditions and health-related symptoms compared with those not reporting CAM use (p < 0.05).
CONCLUSIONS: These findings illustrate that a relatively young adult occupational cohort of military personnel using CAM therapies also report multiple comorbidities which may indicate chronic illness management and poorer overall health.

AB At the age of 43 years, John F. Kennedy was the youngest man ever elected president. Throughout both his campaign and his presidency, he was portrayed as the epitome of youth and vigor. In fact, he had the most complex medical history of anyone to occupy the White House. The recent opening of his White House medical records has provided researchers greater insight into the multiple medical conditions that afflicted Kennedy. A recent review of these records, coupled with other available sources, allows new understanding of his health history that can now be explained in the context of a unifying autoimmune endocrine disorder.

Using mouse models of Ebola virus, we further demonstrate that FGI-106 can protect animals from an otherwise lethal infection when used either in a prophylactic or therapeutic setting. A single treatment, administered 1 day after infection, is sufficient to protect animals from lethal Ebola virus challenge. Cell-based assays also identified inhibitory activity against divergent virus families, which supports a hypothesis that FGI-106 interferes with a common pathway utilized by different viruses. These findings suggest FGI-106 may provide an opportunity for targeting viral diseases. (C) 2009 Elsevier B.V. All rights reserved.

AB A systematic theoretical study of laser-irradiated targets made of material with increasing atomic number has been performed. The formation of energetic light ions resulting from the interaction of an intense ultrashort pulse laser with thin planar targets is investigated theoretically with a two-dimensional relativistic electromagnetic particle-in-cell model. A common parameter, the areal electron density of the foil, can be used to describe qualitatively targets made of different material. By varying either the laser intensity or the target thickness we observe a gradual transition of various ion acceleration mechanisms from one into another. Light ions, such as H(+), Li(3+), C(6+), and Al(13+), can be accelerated to GeV energies with existing laser systems at a laser fluence of 10-20 J/mu m(2).

AB We combine the globular cluster (GC) data for 15 brightest cluster galaxies and use this material to trace the mass-metallicity relations (MMRs) in their globular cluster systems (GCSs). This work extends previous studies which correlate the properties of the MMR with those of the host galaxy. Our combined data sets show a mean trend for the metal-poor subpopulation that corresponds to a scaling of heavy-element abundance with cluster mass Z similar to M(0.30 +/- 0.05). No trend is seen for the metal-rich subpopulation which has a scaling relation that is consistent with zero. We also find that the scaling exponent is independent of the GCS specific frequency and host galaxy luminosity, except perhaps for dwarf galaxies. We present new photometry in (g',i') obtained with Gemini/GMOS for the GC populations around the southern giant ellipticals NGC 5193 and IC 4329. Both galaxies have rich cluster populations which show up as normal, bimodal sequences in the color-magnitude diagram. We test the observed MMRs and argue that they are statistically real, and not an artifact caused by the method we used. We also argue against asymmetric contamination causing the observed MMR as our mean results are no different from other contamination-free studies. Finally, we compare our method to the standard bimodal fitting method (KMM or RMIX) and find our results are consistent. Interpretation of these results is consistent with recent models for GC formation in which the MMR is determined by GC self-enrichment during their brief formation period.

All data were obtained in 2006 and 2007 at the Mount Wilson Observatory, using the 2.5 m Hooker telescope. Separations range from 0.'' 06 to 6.'' 31, with a median of 0.'' 34. These three observing runs concentrated on binaries in need of confirmation (mainly Hipparcos and Tycho pairs), as well as systems in need of improved orbital elements. New orbital solutions have been determined for 35 systems as a result.

TI THE EVOLUTION OF CASSIOPEIA A AT LOW RADIO FREQUENCIES

ID FLUX-DENSITY SCALE; SECULAR DECREASE; MHZ; CAS
AB We have used archival 74 MHz Very Large Array data spanning the last 15 years in combination with new data from the Long-Wavelength Demonstrator Array and data from the literature covering the last 50 years to explore the evolution of Cas A at low radio frequencies. We find that the secular decrease of the flux density of Cas A at similar to 80 MHz is rather stable over five decades of time, decreasing at a rate of 0.7%-0.8% yr(-1). This is entirely consistent with previous estimates at frequencies as low as 38 MHz, indicating that the secular decrease is roughly the same at low frequencies, at least between 38 and 80 MHz. We also find strong evidence for as many as four modes of flux density oscillation about the slower secular decrease with periods of 3.10 +/- 0.02 yr, 5.1 +/- 0.3 yr, 9.0 +/- 0.2 yr, and 24 +/- 2 yr. These are also consistent with fluctuations seen previously to occur on scales of a few years. These results provide compelling motivation for a thorough low-frequency monitoring campaign of Cas A to constrain the nature and physical origins of these fluctuations, and to be able to better predict the flux density of Cas A at any given epoch so that it may be used as a reliable low-frequency calibrator.

Mean B, V, R, I magnitudes at the 5% level are obtained at 1-4 epochs between 2005 and 2007 using the 1 m telescopes at Cerro Tololo Inter-American Observatory and the Naval Observatory Flagstaff Station. Of the 134 sources that have V magnitudes in the Veron & Veron-Cetty catalog, a difference of over 1.0 mag is found for the observed-catalog magnitudes for about 36% of the common sources, and 10 sources show over 3 mag difference. Our first set of observations presented here form the basis of a long-term photometric variability study of the selected reference frame sources to assist in mission target selection and to support QSO multicolor photometric variability studies in general.

AB We report on 1.6GHz Very-Long-Baseline-Interferometry (VLBI) observations of supernova SN 1979C made on 18 November 2002. We derive a model-dependent supernova size. We also present a reanalysis of VLBI observations made by us on June 1999 and by other authors on February 2005. We conclude that, contrary to our earlier claim of strong deceleration in the expansion, SN1979C has been undergoing almost-free expansion (m = 0.91 +/- 0.09; R proportional to t(m)) for over 25 years.

AB Aims. We report the first observation of multiple-periodic propagating disturbances along a fan-like coronal structure simultaneously detected in both intensity and Doppler shift in the Fe XII 195 angstrom line with the EUV Imaging Spectrometer (EIS) onboard Hinode. A new application of coronal seismology is provided based on this observation.
Methods. We analyzed the EIS sit-and-stare mode observation of oscillations using the running difference and wavelet techniques.
Results. Two harmonics with periods of 12 and 25 min are detected. We measured the Doppler shift amplitude of 1-2 km s(-1), the relative intensity amplitude of 3%-5% and the apparent propagation speed of 100-120 km s(-1).
Conclusions. The amplitude relationship between intensity and Doppler shift oscillations provides convincing evidence that these propagating features are a manifestation of slow magnetoacoustic waves. Detection lengths (over which the waves are visible) of the 25 min wave are about 70-90 Mm, much longer than those of the 5 min wave previously detected by TRACE. This difference may be explained by the dependence of damping length on the wave period for thermal conduction. Based on a linear wave theory, we derive an inclination of the magnetic field to the line-of-sight about 59 +/- 8 degrees, a true propagation speed of 128 +/- 25 km s(-1) and a temperature of 0.7 +/- 0.3 MK near the loop's footpoint from our measurements.

AB We investigate the effect of the circumstellar medium density profile on the X-ray emission from outer ejecta knots in the Cassiopeia A supernova remnant using the 1 Ms Chandra observation. The spectra of a number of radial series of ejecta knots at various positions around the remnant are analyzed using techniques similar to those devised in previous papers. We can obtain a reasonable match to our data for a circumstellar density profile proportional to r(-2) as would arise from the steady dense wind of a red supergiant, but the agreement is improved if we introduce a small (0.2-0.3 pc) central cavity around the progenitor into our models. Such a profile might arise if the progenitor emitted a fast tenuous stellar wind for a short period immediately prior to explosion. We review other lines of evidence supporting this conclusion. The spectra also indicate the widespread presence of Fe-enriched plasma that was presumably formed by complete Si burning during the explosion, possibly via alpha-rich freezeout. This component is typically associated with hotter and more highly ionized gas than the bulk of the O- and Si-rich ejecta.

AB Erupting filaments are sometimes observed to undergo a rotation about the vertical direction as they rise. This rotation of the filament axis is generally interpreted as a conversion of twist into writhe in a kink-unstable magnetic flux rope. Consistent with this interpretation, the rotation is usually found to be clockwise ( as viewed from above) if the post-eruption arcade has right-handed helicity, but counterclockwise if it has left-handed helicity. Here, we describe two non-active-region filament events recorded with the Extreme-Ultraviolet Imaging Telescope on the Solar and Heliospheric Observatory in which the sense of rotation appears to be opposite to that expected from the helicity of the post-event arcade. Based on these observations, we suggest that the rotation of the filament axis is, in general, determined by the net helicity of the erupting system, and that the axially aligned core of the filament can have the opposite helicity sign to the surrounding field. In most cases, the surrounding field provides the main contribution to the net helicity. In the events reported here, however, the helicity associated with the filament "barbs" is opposite in sign to and dominates that of the overlying arcade.

AB In this paper we present high-resolution 4.7 mu m spectra of the isolated Herbig Be star HD 100546. HD 100546 has been the subject of intense scrutiny because it is a young nearby star with a transitional disk. We observe the Delta(v) = 1 rovibrational CO transitions in order to clarify the distribution of warm gas in the inner disk. Modeling of the CO spectrum indicates that the gas is vibrationally excited by collisions and UV fluorescence. The observed emission extends from 13 to 100 AU. The inner edge of the molecular gas emission is consistent with the inner edge of the optically thick dust disk indicating that the inner hole is not simply a hole in the dust opacity but is likely cleared of gas as well. The rotational temperature of the CO is similar to 1000 K-much hotter than the similar to 200 K CO in the otherwise similar transitional disk surrounding HD 141569. The origin of this discrepancy is likely linked to the brighter polycyclic aromatic hydrocarbon emission observed toward HD 100546. We use the excitation of the CO to constrain the geometry of the inner disk and comment on the evolutionary state of the system.

AB Sea surface height (SSH), sea surface temperature (SST), and surface currents derived from satellite observations are analyzed to investigate signals of equatorial Kelvin and tropical instability waves (TIWs) in the Pacific Ocean. A wavenumber-frequency spectral analysis of SSH and SST anomalies was performed in order to examine their space and time variability. Significant spectral peaks along the dispersion curves of the first baroclinic mode Rossby and Kelvin waves are found in the SSH spectrum, indicating that the analysis can effectively identify the signals of equatorial waves in the upper ocean. A prominent peak in SSH fields at around 33 days and 1500 km wavelength along the Rossby wave dispersion curve is evident, and a similar peak is also found in SST fields. This upper ocean variability on these space and time scales is shown to be associated with TIWs. The spatial structure of 33-day TIWs is further examined based on an analysis of time series filtered in the frequency-wavenumber domain. The phase relationship between SSH, SST, and surface velocity associated with TIWs is described based on a cross-correlation analysis. Also, the interannual variability of TIW activity is compared with that of ENSO, showing a moderate correlation. (C) 2008 Elsevier B.V. All rights reserved.

AB We investigated patterns of primary production across prairie saline lakes in the central and northern Great Plains of the United States. Based on comparative lake sampling in 2004, seasonal predictors of algal primary productivity were identified within subsets of similar lakes using a combination of Akaike's information criterion (AIC) and classification and regression trees (CART). These models indicated complex patterns of nutrient limitation by nitrogen (N), phosphorus (P), and iron (Fe) within different lake groups. Nutrient enrichment assays (control, + Fe, + N, + P, + N + P) were performed in spring and summer of 2006 to determine if phytoplankton in selected lakes followed predicted patterns of nutrient limitation. Both the comparative lake sampling and experimental results indicated that N limitation was widespread in these prairie lakes, with evidence for secondary P limitation in certain lakes. In the experiments, iron did not stimulate primary production. Our results suggest that given the diverse geochemical nature of these lakes, classification models that separate saline lakes into subsets may be an effective method for improving predictions of algal production.

AB We seek in this paper to differentiate driven nonlinear systems using only a single output signal from the driven system. We do not have access to the driving signal. We demonstrate the phase space identification techniques with an experimental model of a radio transmitter. We restrict the driving signals to nearly periodic signals, because these types of signals are the most common signals used in real transmitters. We find that by studying our transmitter as a driven nonlinear system, we are able to distinguish one transmitter from another. This work may have consequences for real transmitters.

DT Article
DE chaos; correlation methods; radar detection; sonar detection
AB The standard method used for detecting signals in radar or sonar is cross correlation. The accuracy of the detection with cross correlation is limited by the bandwidth of the signals. We show that by calculating the cross correlation based on points that are nearby in phase space rather than points that are simultaneous in time, the detection accuracy is improved. The phase space correlation technique works for some standard radar signals, but it is especially well suited to chaotic signals because trajectories that are adjacent in phase space move apart from each other at an exponential rate.

DT Article
DE Simulation; Design of experiments; Screening; Hierarchy organizational

AB Simulation experiments are typically faster, cheaper and more flexible than physical experiments. They are especially useful for pilot studies of complicated systems where little prior knowledge of the system behavior exists. One key characteristic of simulation experiments is the large number of factors and interactions between factors that impact decision makers. Traditional simulation approaches offer little help in analyzing large numbers of factors and interactions, which makes interpretation and application of results very difficult and often incorrect. In this paper we implement and demonstrate efficient design of experiments techniques to analyze large, complex simulation models. Looking specifically within the domain of organizational performance, we illustrate how our approach can be used to analyze even immense results spaces, driven by myriad factors with sometimes unknown interactions, and pursue optimal settings for different performance measures. This allows analysts to rapidly identify the most important, results-influencing factors within simulation models, employ an experimental design to fully explore the simulation space efficiently, and enhance system design through simulation. This dramatically increases the breadth and depth of insights available through analysis of simulation data, reduces the time required to analyze simulation-driven studies, and extends the state of the art in computational and mathematical organization theory.

AB Currently, two main known mechanisms of aluminum (Al) nanoparticle reaction are discussed in the literature, namely these based on diffusion through an oxide shell melt dispersion. The two mechanisms lead to opposite predictions in nanoparticle design. This diffusion mechanism suggests that the reduction or complete elimination of the oxide shell will increase Al reactivity, whereas the melt-dispersion mechanism suggests an increase in initial oxide thickness up to an optimal value. The goal of this study is to perform critical experiments in a confined flame tube apparatus to compare these two predictions. Specifically, the flame propagation rates of perfluoroalkyl carboxylic acid (C13F27COOH). treated Al nanoparticles with and without an alumina shell were measured. Results show that when there is no alumina passivation shell encasing the Al core, the flame rate decreases by a factor of 22-95 and peak pressure decease by 3 orders of manitude, in comparision with the A1 particles with an oxide shell. These results imply that the melt-dispersion reaction mechanism is responisble for high flame propagation rates observed in these confined tube experiments.

AB Having examined the energetic properties of dinitrourea (DNU) as it monoanion, this study was extended to the syntheses and characterization or ten DNU dianionic sails by the metathesis of tetrazolium and guanidinium sulfates with in situ-generated barium DNU in aqueous solution, These materials are impact insensitive. They were fully characterized by NMR, elemental analysis, IR, DSC, and TGA. Bis(guanylguanidinium) DNU dianionic salt (9) crystallizes in the triclinic space group P-1, The detonation pressure (P) values calculated for these salts range from 19.6 to 29.1 GPa, and the detonation velocities (gamma(D)) range from 7521 to 8908 m/s, which make them competitive energetic materials. The chlorine-free DNU dianionic salts are green, and the straightforward synthesis. The process avoids the use of costly silver DNU dianion compares, very favorably with dinitramide as it novel oxidative Species.

AB Expressions for the chemical potential of an Einstein solid, and of ideal Fermi and Bose gases in an external one-dimensional oscillatory trap, are calculated by two different methods and are all found to share the same functional form. These derivations are easier than traditional textbook calculations for an ideal gas in an infinite three-dimensional square well. Furthermore, the results indicate some important features of chemical potential that could promote student learning in an introductory course in statistical mechanics at the undergraduate level.

AB An expression is developed for the energy dissipated when a constant external force is suddenly applied to the end of a particle moving in 1D subject to a conservative restoring force and a general damping force. Assuming the particle was initially at rest and ends up in static equilibrium, the fraction of the mechanical energy lost depends only on the conservative force and on the net displacement of the particle. Mechanical models are suggested to illustrate the ideas and their capacitor circuit analogies. The treatment is appropriate for an intermediate-level undergraduate mechanics course.

AB The studies emphasize investigation of plasma formation, implosion, and radiation features as a function of two load configurations: compact multi-planar and cylindrical wire arrays. Experiments with different Z-pinch loads were performed on 1.6 MA, 100 ns, Zebra generator at University of Nevada, Reno. The multi-planar wire arrays (PWAs) were studied in open and closed configurations with Al, Cu, brass, Mo and W wires. In the open magnetic configurations (single, double, triple PWAs) magnetic fields are present inside the arrays from the beginning of discharge, while in closed configurations (prism-like PWA) the global magnetic field is excluded inside before plasma flow occurs. The new prism-like PWA allows high flexibility in control of implosion dynamics and precursor formation. The spectral modeling, magneto-hydrodynamic (MHD) and wire ablation dynamic model (WADM) codes were used to describe the plasma evolution and plasma parameters. Experimentally observed electron temperature and density in multiple bright spots reached 1.4 keV and 5 x 10(21) cm(-3), respectively. Two types of bright spots were observed. With peak currents up to 1.3 MA opacity effects became more pronounced and led to a limiting of the X-ray yields from compact cylindrical arrays. Despite different magnetic energy to plasma coupling mechanisms early in the implosion a comparison of compact double PWA and cylindrical WA results indicates that during the stagnation stage the same plasma heating mechanism may occur. The double PWA was found to be the best radiator tested at University scale 1 MA generator. It is characterized by a combination of larger yield and power, mm-scale size, and provides the possibility of radiation pulse shaping. Further, the newer configuration, the double PWA with skewed wires, was tested and showed the possibility of a more effective X-ray generation. (c) 2009 Elsevier B.V. All rights reserved.

AB When external events disrupt the normal flow of organizational and relational routines and practices, an organization's latent capacity to rebound activates to enable positive adaptation and bounce back. This article examines an unexpected organizational crisis (a shooting and standoff in a business school) and presents a model for how resilience becomes activated in such situations. Three social mechanisms describe resilience activation. Liminal suspension describes how crisis temporarily undoes and alters formal relational structures and opens a temporal space for organization members to form and renew relationships. Compassionate witnessing describes how organization members' interpersonal connections and opportunities for engagement respond to individuals' needs. And relational redundancy describes how organization members' social capital and connections across organizational and functional boundaries activate relational networks that enable resilience. Narrative accounts from the incident support the induced model.

AB Recently, global biomass-burning research has grown from what was primarily a climate field to include a vibrant air quality observation and forecasting community. While new fire monitoring systems are based on fundamental Earth Systems Science (ESS) research, adaptation to the forecasting problem requires special procedures and simplifications. In a reciprocal manner, results from the air quality research community have contributed scientifically to basic ESS. To help exploit research and data products in climate, ESS, meteorology and air quality biomass burning communities, the joint Navy, NASA, NOAA, and University Fire Locating and Modeling of Burning Emissions (FLAMBE) program was formed in 1999. Based upon the operational NOAA/NESDIS Wild-Fire Automated Biomass Burning Algorithm (WF_ABBA) and the near real time University of Maryland/NASA MODIS fire products coupled to the operational Navy Aerosol Analysis and Prediction System (NAAPS) transport model, FLAMBE is a combined ESS and operational system to study the nature of smoke particle emissions and transport at the synoptic to continental scales. In this paper, we give an overview of the FLAMBE system and present fundamental metrics on emission and transport patterns of smoke. We also provide examples on regional smoke transport mechanisms and demonstrate that MODIS optical depth data assimilation provides significant variance reduction against observations. Using FLAMBE as a context, throughout the paper we discuss observability issues surrounding the biomass burning system and the subsequent propagation of error. Current indications are that regional particle emissions estimates still have integer factors of uncertainty.

AB The problem of cooperative track detection by a dynamic sensor network arises in many applications, including security and surveillance, and tracking of endangered species. Several authors have recently shown that the quality-of-service of these networks can be statically optimized by placing the sensors in the region of interest (ROI) via mathematical programming. However, if the sensors are subject to external forcing, such as winds or currents, they may be rapidly displaced, and their quality-of-service may be significantly deteriorated over time. The novel approach presented in this paper consists of placing the sensors in the ROI based on their future displacement, which can be estimated from environmental forecasts and sensor dynamic models. The sensor network deployment is viewed as a new problem in dynamic computational geometry, in which the initial positions of a family of circles with time-varying radii and positions are to be optimized subject to sets of algebraic and differential equations. When these equations are nonlinear and time-varying, the optimization problem does not have an exact solution, or global optimum, but can be approximated as a finite-dimensional nonlinear program by discretizing the quality-of-service and the dynamic models with respect to time. Then, a near-optimal solution for the initial sensor positions is sought by means of sequential quadratic programming. The numerical results show that this approach can improve quality-of-service by up to a factor of five compared to existing techniques, and its performance is robust to propagated modeling and deployment errors.

AB The Net-Centric Adapter for Legacy Systems (NCALS) is a software technology that makes legacy system data and services available in near real-time to the military Global Information Grid (GIG). The intent of NCALS is to lower the cost and risk, and to decrease the time required for legacy systems to comply with U. S. Department of Defense (DoD) net-centric technical standards. Many different systems could use a common, configurable NCALS software component to comply with these standards. The benefit to the warfighter is improved interoperability with joint and coalition forces. NCALS enables legacy systems to move to a Service-Oriented Architecture (SOA) compatible with the GIG without requiring a costly and risky re-architecture of their legacy software. In addition, NCALS enables mission critical systems such as weapon systems to segregate their real-time, mission critical software from enterprise integration software. This maintains the safety and security required by such systems, while accommodating rapid changes in Internet-based, enterprise technologies. This paper will discuss the legacy system challenge and describe a technology prototype developed by the Naval Surface Warfare Center (NSWC) Dahlgren to realize the NCALS concept. The prototype works automatically, behind the scenes, to expose legacy data to the GIG and to make GIG data available to legacy systems.

AB A complete photovoltaic cell was fabricated using only a handheld airbrush, dilute solutions of CdSe and CdTe nanorods, commercially available silver paint, and transparent-conducting-electrode-coated glass. Produced and stored under ambient conditions, these fully functioning solar cells are stable for months. As a heterojunction cell, the migration of carriers within the CdTe and CdSe layers is polarity-dependent, which directly contributes to the photoinduced voltaic cell response observed. The suitability of a handheld airbrush to create high-quality films by varying solution concentration, air pressure, and nanorod surface functionalization was explored. Notably, ultrasmooth surfaces comparable to spin-coated quality films can be formed from 20 to 500 nm thickness, with continuous, uninterrupted optical domains such that strong light diffraction is observed. While current estimated efficiency is low(<0.01%), this method demonstrates the potential of solar cells that can be incorporated into a variety of devices of unconventional size or design.

AB Objective: Posttraumatic stress disorder (PTSD) is an important source of morbidity in military personnel, but its relationship with characteristics of battle injury has not been well defined. The aim of this study was to characterise the relationship between injury-related factors and PTSD among a population of battle injuries.
Patients and methods: A total of 831 American military personnel injured during combat between September 2004 and February 2005 composed the study population. Patients were followed through November 2006 for diagnosis of PTSD (ICD-9 309.81) or any mental health outcome (ICD-9 290-319).
Results: During the follow-up period, 31.3% of patients received any type of mental health diagnosis and 17.0% received a PTSD diagnosis. Compared with minor injuries those with moderate (odds ratio [OR], 2.37; 95% confidence interval [Cl], 1.61-3.48), serious (OR, 4.07; 95% Cl, 2.55-6.50), and severe (OR, 5.22; 95% Cl, 2.74-9.96) injuries were at greater risk of being diagnosed with any mental health outcome. Similar results were found for serious (OR, 3.03; 95% Cl, 1.81-5.08) and severe (OR, 3.21; 95% Cl, 1.62-6.33) injuries with PTSD diagnosis. Those with gunshot wounds were at greater risk of any mental health diagnosis, but not PTSD, in comparison with other mechanisms of injury (OR 2.07; 95% Cl, 1.35, 3.19). Diastolic blood pressure measured postinjury was associated with any mental health outcome, and the effect was modified by injury severity.
Conclusions: Injury severity was a significant predictor of any mental health diagnosis and PTSD diagnosis. Gunshot wounds and diastolic blood pressure were significant predictors of any mental health diagnosis, but not PTSD. Further studies are needed to replicate these results and elucidate potential mechanisms for these associations. (C) 2009 Elsevier Ltd. All rights reserved.

AB US military personnel are routinely screened for HIV infection. Herpes simplex virus type 2 (HSV-2) is a risk factor for HIV acquisition. To determine the association between HSV-2 and HIV, a matched case-control study was conducted among US Army and Air Force servicemembers with incident HIV infections (cases) randomly matched with two HIV-uninfected servicemembers (controls) between 2000 and 2004. HSV-2 prevalence was significantly higher among cases (30.3%, 138/456) than among controls (9.7%, 88/912, P < 0.001). HSV-2 was strongly associated with HIV in univariate (odds ratio [OR] = 4.2, 95% confidence interval [CI] = 3.1-5.8) and multiple analyses (adjusted [OR] = 3.9, 95% CI = 2.8-5.6). The population attributable risk percentage of HIV infection due to HSV-2 was 23%. Identifying HSV-2 infections may afford the opportunity to provide targeted behavioural interventions that could decrease the incidence of HIV infections in the US military population; further studies are needed.

AB We present a study of the polarimetric information content of dual-pol imaging modes and dual-pol imaging extended by polarimetric scattering models. We compare Wishart classifications both among the partial polarimetric datasets and against the full quad-pol dataset. Our emphasis is the inter-comparisons between the classification results based on dual-pol modes, compact polarimetric modes and scattering model extensions of the compact polarimetric modes. We primarily consider novel dual-pol modes, e.g. transmitting a circular polarization and receiving horizontal and vertical polarizations, and the pseudo-quad-pol data derived from polarimetric scattering models based on dual-pol data. We show that the overall classification accuracy of the pseudo-quad-pol data is essential the same as the classification accuracy obtained directly employing the underlying dual-pol imagery.

TI Sensitivity of Typhoon Track Predictions in a Regional Prediction System

AB Tropical cyclone (TC) track predictions from the operational regional nonhydrostatic TC forecast system of the Taiwanese Central Weather Bureau (CWB) are examined for their sensitivities to initial and lateral boundary conditions. Five experiments are designed and discussed, each using a combination of different initial and lateral boundary conditions coming either from the CWB or the National Centers for Environmental Prediction (NCEP) global forecast system. Eight typhoons in the western Pacific Ocean with 51 cases in 2004 and 2005 are tested with the five designed experiments for the 3-day forecast. The average track forecasts are the best when both the initial and lateral boundary conditions are from the NCEP global forecast system. This reflects the generally superior performance of the NCEP global forecast system relative to that of the CWB. Using different lateral boundary conditions has a greater impact on the track than using different initial conditions. Diagnostics using piecewise inversion of potential vorticity perturbations are carried out to identify synoptic features surrounding the featured typhoon that impact the track the most in each experiment. For the two cases demonstrated with the largest track improvement using NCEP global fields, the diagnostics indicate that the prediction of the strength and extent of the subtropical high in the western Pacific plays the major role in affecting these storm tracks. Using the analysis and predictions of the CWB global forecast system as the initial and lateral boundary conditions produces an overintensified subtropical ridge in the regional TC forecast model. Because most of the typhoons studied are located in the southwestern peripheral of the western Pacific subtropical high, the stronger steering from the more intense and extended high system is the main cause of the poleward bias in the predicted typhoon tracks in the operational run, which uses the CWB global forecast fields. The study suggests that, when efforts are made to improve a regional TC forecast model, it is also critically important to improve the global forecast system that provides the lateral boundary and initial conditions to the regional system.

Pulsed threshold current densities as low as 394 A/cm(2) and voltage efficiencies as high as 76% are obtained at 300 K. The low pulsed threshold power densities (0.9-1.6 kW/cm(2) at 300 K) imply that ambient-temperature cw operation should be possible over the entire spectral band once optimized narrow ridges can be fabricated.

AB Introduction: The purpose of this study was to assess the percentage of new endodontic files (taken directly from the manufacturers' packages) that were contaminated with viable microorganisms and to determine the amount of time new files needed to be immersed in 6% sodium hypochlorite to achieve sterility. Methods: Endodontic files from four manufacturers were placed either immediately in thioglycolate broth or immersed in 6% sodium hypochlorite for 1, 2, or 5 minutes before placement in the broth. The files were aerobically incubated for 72 hours and sterility determined by the absence of broth turbidity, as determined by a blinded examiner. The data were analyzed using the Cochran-Q test followed by the McNemar test for pair-wise comparisons. The level of statistical significance was set at alpha = 0.05. Results: When pooling all manufacturers' files, no significant differences were found between groups. Conclusion: New files demonstrated a 6% contamination rate and none of the immersion times in NaOCl achieved file sterility. (J Endod 2009;35:1253-1254)

TI Optimal Control of a Librating Electrodynamic Tether Performing a
Multirevolution Orbit Change
SO JOURNAL OF GUIDANCE CONTROL AND DYNAMICS
LA English
DT Article
AB Satellites that use low-thrust propulsion systems for maneuvering, although efficient, can take a long time to complete significant orbit changes. Determining the nonlinear optimal controls for such multirevolution maneuvers using the instantaneous orbital state dynamics can he riddled with numerical errors and are often subject to long computation times, due to the large number of discretization nodes required by the optimization algorithm. An approach to optimal control of an electrodynamic tether is examined using averaged orbital state dynamics as constraints instead of instantaneous dynamic constraints. A mean-square libration state is introduced in the dynamic model that captures the average of the out-of-plane libration of the tether. A sample long-term optimal orbit change maneuver of a librating electrodynamic tether subject to atmospheric drag is investigated. The method of averaging is employed to transform the optimal control problem from the time domain into Fourier space, in which the complex problem is significantly reduced to a Zermelo-type problem that is solved using a pseudospectral method. To validate the dynamic model of averaged states, the instantaneous states are propagated from the initial conditions using the resulting optimal controls.

AB The fundamental dynamics of virtual and traditional face-to-face teams may be very different. The purpose of this study is to empirically examine and assess the moderating effects of virtuality on the antecedents and outcome of trust, where virtuality is measured along a continuum from face to face (no virtuality) to fully virtual rather than the more common approach of dichotomizing teams into two groups (i.e., face to face and virtual). The sample includes 116 different new product development teams from a variety of industries. The antecedents of trust that are studied are familiarity, goal clarity, training, relationship conflict, and process conflict. The outcome of trust is analyzed by determining how the impact of trust on cooperation changes as the level of virtuality changes. Primary findings are as follows: (1) Relationship conflict can be more detrimental to virtual teams than face-to-face teams because it is very difficult for team members of virtual teams to resolve their interpersonal disputes; (2) goal clarity is more important for face-to-face teams and less important for virtual teams in creating trust among team members; and (3) the impact of trust on cooperation is less for virtual teams than face-to-face teams. The primary implication for researchers and practice of these findings is that the role and importance of trust in virtual teams needs to be reevaluated. Managers using virtual teams need to realize that interpersonal relationships in virtual teams do not evolve in the same manner as face-to-face teams and may require different management techniques to be successful.

AB In this paper Creamer's [(1996). J. Acoust. Soc. Am. 99, 2825-2838] transport equation for the mode amplitude coherence matrix resulting from coupled mode propagation through random fields of internal waves is examined in more detail. It is shown that the mode energy equations are approximately independent of the cross mode coherences, and that cross mode coherences and mode energy can evolve over very similar range scales. The decay of cross mode coherence depends on the relative mode phase randomization caused by coupling and adiabatic effects, each of which can be quantified by the theory. This behavior has a dramatic effect on the acoustic field second moments like mean intensity. Comparing estimates of the coherence matrix and mean intensity from Monte Carlo simulation, and the transport equations, good agreement is demonstrated for a 100-Hz deep-water example.

ID WAVE-PROPAGATION; RANDOM-MEDIA; LONG-RANGE; PULSE-PROPAGATION; COHERENCE
AB Observations of scattering of low-frequency sound in the ocean have focused largely on effects at long ranges, involving multiple scattering events. Fluctuations due to one and two scattering events are analyzed here, using 75-Hz broadband signals transmitted in the eastern North Pacific Ocean. The experimental geometry gives two purely refracted arrivals. The temporal and vertical scales of phase and intensity fluctuations for these two ray paths are compared with predictions based on the weak fluctuation theory of Munk and Zachariasen, which assumes internal-wave-induced sound-speed perturbations [J. Acoust. Soc. Am. 59, 818-838 (1976)], The comparisons show that weak fluctuation theory describes the frequency and vertical-wave-number spectra of phase and intensity for the two paths reasonably well. The comparisons also show that a resonance condition exists between the local acoustic ray and the internal-wave field, as predicted by Munk and Zachariasen, such that only internal waves whose crests are parallel to the local ray path contribute to acoustic scattering. This effect leads to filtering of the acoustic spectra relative to the internal-wave spectra, such that steep rays do not acquire scattering contributions due to low-frequency internal waves.

AB Marfan syndrome is a variable autosomal dominant disorder; most cases result from mutations of fibrillin-1. Diagnosis is guided by the Ghent nosology. The condition may manifest in the cardiovascular and ocular systems. Musculoskeletal manifestations include scoliosis, dural ectasia, protrusio acetabuli, and ligamentous laxity. Compared with patients with idiopathic scoliosis, patients with Marfan syndrome tend to have scoliosis that progresses at a faster rate and is more resistant to bracing; undergo scoliosis surgery complicated by greater blood loss, pseudarthrosis, and additional curvature; and have more frequent occurrences of dural ectasia, which may cause headaches, leg pain, or perineal pain. Protrusio acetabuli may result in hip joint arthritis and may require valgus osteotomy or total hip arthroplasty.

AB An experimental study was conducted to investigate the usefulness of electrostatic and conventional sprayers for barrier applications. Two conventional and three electrostatic sprayers were used in the study. Usefulness of the sprayers was rated based on penetration of spray into and deposition onto 2 sides of leaves on natural vegetation. Bifenthrin (Talstar (TM) adulticide) was applied at labeled rate, fluorescent dye was added to the tank mix Lis tracer, and all sprayers applied the dye and insecticide at the same rate. The results indicated that sprayers producing larger droplets produced significantly higher deposition on vegetation in barrier applications than the sprayers producing smaller droplets. Sprayers with higher air velocity at the nozzle discharge proved significantly better for barrier sprays than the sprayers with lower air velocity. Electrostatic sprayers did not show any improvement in deposition oil vegetation or in penetration into vegetation over the conventional sprayers. There was no difference in deposition between truck-mounted and backpack sprayers.

AB Numerous spray machines are used to apply pesticides for the control of human disease vectors, such as mosquitoes and flies, and the selection and setup of these machines significantly affects the level of control achieved during an application. The droplet spectra produced by 9 different ultra-low-volume sprayers with oil- and water-based spray solutions were evaluated along with 2 thermal foggers with the use of diesel-based spray solutions. The droplet spectra from the sprayers were measured with the use of laser diffraction droplet sizing equipment. The volume median diameter from the sprayers ranged from 14.8 to 61.9 mu m for the oil-based spray solutions and 15.5 to 87.5 mu m for the water-based spray solutions. The 2 thermal foggers generated sprays with a volume median diameter of 3.5 mu m. The data presented will allow spray applicators to select the spray solution and sprayer that generate the droplet-size spectra that meet the desired specific spray application scenarios.

AB The use of pesticide-treated vegetation as a barrier for control of nuisance and disease-bearing mosquitoes has become an option for mosquito management for home owners and public health and mosquito control professionals. Potted wax myrtle and azalea plants were treated with bifenthrin (0.79% AI) at maximum label rate using backpack and electrostatic sprayers and exposed to various treatments that could affect the residual degradation of the applied pesticides. Treatments included leaf aspect, simulated rainfall, shade, and natural sun exposure with the residual effectiveness of leaves examined in tarsal contact Petri dish assays using laboratory-reared Aedes aegypti. There was no significant difference in efficacy between the adaxial (top) or abaxial (bottom) surfaces of electrostatically or backpack-treated leaves. Significant differences existed between application method, plant species, and exposure with most significant effects between weeks 1 and 4. Simulated heavy rainfalls applied 3 times weekly reduced knockdown by leaves treated with electrostatic and backpack methods with reductions seen as soon as 1 wk after treatment. Reductions were seen with both wax myrtle and azalea leaves and after 1, 4, and 24 h contact of mosquitoes to leaves. Placement of plants with full exposure to sunlight also significantly reduced efficacy compared to plants placed in the shade. Differences were observed most often for 4 and 24 h knockdown counts, and significant decreases were seen from week 4 onwards. Clearly factors such as rain and exposure to sun impact degradation of efficacy of bifenthrin-treated vegetation in the field. Degradation of bifenthrin efficacy was slowest in sites protected from rain and sun, which coincide with preferred resting site locations for many mosquito species.

AB One of the outstanding problems of terahertz spectroscopy is the measurement of the underlying vibrational spectrum of a molecular solid, where individual vibrational transitions are often merged into broad absorption features by line-broadening processes. We address this problem using the technique of waveguide terahertz time-domain spectroscopy (THz-TDS), whereby a thin polycrystalline molecular film is contained within a single-mode metal parallel plate waveguide. Thin films of the molecular solids cyclotrimethylene trinitramine (RDX explosive) and 4-iodo-4'-nitrobiphenyl serve to demonstrate the ability of waveguide THz-TDS to resolve previously unseen complex underlying THz vibrational spectra at cryogenic temperatures, with linewidths as narrow as 7 GHz. With such narrow linewidths we are able to demonstrate the measurement of vibrational line-center frequencies to a precision of 1 GHz. (C) 2009 Optical Society of America

AB Background: The use of mineral (clay) or biologic (chitosan) materials has improved the efficacy of dressings used in the bleeding control of noncompressible areas. A series of novel manufactured products already evaluated in a vascular transection model was further compared in a severe vascular puncture injury model.
Methods: Ten hemostatic dressings were tested in anesthetized Yorkshire swine hemorrhaged for 45 seconds in a femoral arterial puncture model. Application of these dressings was followed by 5 minutes of compression (about 175 mm Hg), and at 15 minutes, 500 mL resuscitation fluid (Hextand) was infused during a 30-minute period. The animals were monitored for a 3-hour experimental observation period. Primary outcomes were incidence of bleeding after dressing application and animal survival.
Results. Blood loss was 18.8% +/- 5.2% estimated blood volume (EBV) after 45 seconds of free bleeding. Relative performance of dressings is characterized as groups of dressings that performed similarly. Recurrence of bleeding after application was observed with most dressings and was lower with Woundstat, Celox, X-Sponge, and ACS+ (35% +/- 49%) compared with FP-21, Hemcon, Chitoflex, and Bloodstop (79% +/- 43%; P < .01). Blood loss after treatment was 25.3% +/- 18.4% EBV for the top four dressings and 53.0% +/- 18.4% EBV for the bottom four (P < .05). Survival was higher for top four vs bottom four dressings (78% +/- 12% vs 25% +/- 0%, respectively; P < .01). Overall performance of these dressings according to survival, incidence of bleeding, and post-treatment blood loss, yielded similar ranking as with a previously tested transection injury model.
Conclusions. The findings indicated that the efficacy of Woundstat, Celox, X-Sponge, and ACS+ were similar and superior in improving survival, hemostasis, and maintenance of mean arterial pressure in an actively bleeding wound caused in this severe vascular injury model.

AB We develop a dynamic model in which Operation Iraqi Freedom (OIF) servicemembers incur a random amount of combat stress during each month of deployment, develop posttraumatic stress disorder (PTSD) if their cumulative stress exceeds a servicemember-specific threshold, and then develop symptoms of PTSD after an additional time lag. Using Department of Defense deployment data and Mental Health Advisory Team PTSD survey data to calibrate the model, we predict that-because of the long time lags and the fact that some surveyed servicemembers experience additional combat after being surveyed-the fraction of Army soldiers and Marines who eventually suffer from PTSD will be approximately twice as large as in the raw survey data. We cannot put a confidence interval around this estimate, but there is considerable uncertainty (perhaps +/-30%). The estimated PTSD rate translates into approximate to 300,000 PTSD cases among all Army soldiers and Marines in OIF, with approximate to 20,000 new cases each year the war is prolonged. The heterogeneity of threshold levels among servicemembers suggests that although multiple deployments raise an individual's risk of PTSD, in aggregate, multiple deployments lower the total number of PTSD cases by approximate to 30% relative to a hypothetical case in which the war was fought with many more servicemembers (i.e., a draft) deploying only once. The time lag dynamics suggest that, in aggregate, reserve servicemembers show symptoms approximate to 1-2 years before active servicemembers and predict that >75% of OIF servicemembers who self-reported symptoms during their second deployment were exposed to the PTSD-generating stress during their first deployment.

AB The periodic inverse scattering transform (PIST) is a powerful analytical tool in the theory of integrable, nonlinear evolution equations Osborne pioneered the use of the PIST in the analysis of data form inherently nonlinear physical processes In particular, Osborne's so-called nonlinear Fourier analysis has been successfully used in the Study of waves whose dynamics are (to it good approximation) governed by the Korteweg-de Vries equation In this paper, the mathematical details and a new application of the PIST are discussed. The numerical aspects of and difficulties in obtaining the nonlinear Fourier (i.e., PIST) spectrum of a physical data set are also addressed. In particular, an improved bracketing of the "spectral eigenvalues" (i.e.. the +/- 1 crossings of the Floquet discriminant) and a new root-finding algorithm for computing the latter are proposed Finally, if is shown how the PIST can be used to gain insightful information about the phenomenon soliton-induced acoustic resonances, by computing the nonlinear Fourier spectrum of a data set from a simulation of internal solitary wave generation and propagation in the Yellow Sea (C) 2009 IMACS Published by Elsevier B.V.

AB Objectives: We analyze whether hazard rates of shutting down trauma centers are higher due to financial pressures or in areas with vulnerable populations (such as minorities or the poor).
Materials and Methods: This is a retrospective study of all hospitals with trauma center services in urban areas in the continental US between 1990 and 2005, identified from the American Hospital Association Annual Surveys. These data were linked with Medicare cost reports, and supplemented with other sources, including the Area Resource File. We analyze the hazard rates of trauma center closures among several dimensions of risk factors using discrete-time proportional hazard models.
Results: The number of trauma center closures increased from 1990 to 2005, with a total of 339 during this period. The hazard rate of closing trauma centers in hospitals with a negative profit margin is 1.38 times higher than those hospitals without the negative profit margin (P < 0.01). Hospitals receiving more generous Medicare reimbursements face a lower hazard of shutting down trauma centers (ratio: 0.58, P < 0.01) than those receiving below average reimbursement. Hospitals in areas with higher health maintenance organizations penetration face a higher hazard of trauma center closure (ratio: 2.06, P < 0.01). Finally, hospitals in areas with higher shares of minorities face a higher risk of trauma center closure (ratio: 1.69, P < 0.01). Medicaid load and uninsured populations, however, are not risk factors for higher rates of closure after we control for other financial and community characteristics.
Conclusions: Our findings give an indication on how the current proposals to cut public spending could exacerbate the trauma closure particularly among areas with high shares of minorities. In addition, given the negative effect of health maintenance organizations on trauma center survival, the growth of Medicaid managed care population should be monitored. Finally, high shares of Medicaid or uninsurance by themselves are not independent risk factors for higher closure as long as financial pressures are mitigated. Targeted policy interventions and further research on the causes, are needed to address these systems-level disparities.

AB In order to properly utilize remotely sensed precipitation estimates in hydrometeorological applications, knowledge of the accuracy of the estimates are needed. However, relatively few ground validation networks operate with the necessary spatial density and time-resolution required for validation of high-resolution precipitation products (HRPP) generated at fine space and time scales (e.g., hourly accumulations produced on a 0.25A degrees spatial scale). In this article, we examine over-land validation statistics for an operationally designed, meteorological satellite-based global rainfall analysis that blends intermittent passive microwave-derived rainfall estimates aboard a variety of low Earth-orbiting satellite platforms with sub-hourly time sampling capabilities of visible and infrared imagers aboard operational geostationary platforms. The validation dataset is comprised of raingauge data collected from the dense, nearly homogeneous, 1-min reporting Automated Weather Station (network of the Korean Meteorological Administration during the June to August 2000 summer monsoon season. The space-time RMS error, mean bias, and correlation matrices were computed using various time windows for the gauge averaging, centered about the satellite observation time. For +/- 10 min time window, a correlation of 0.6 was achieved at 0.1A degrees spatial scale by averaging more than 3 days; coarsening the spatial scale to 1.8A degrees produced the same correlation by averaging over 1 h. Finer than approximately 24-h and 1A degrees time and space scales, respectively, a rapid decay of the error statistics was obtained by trading-off either spatial or time resolution. Beyond a daily time scale, the blended estimates were nearly unbiased and with an RMS error of no worse than 1 mm day(-1).

AB Extrapulmonary manifestations of Mycoplasma pneumoniae are well described, including a subset of central nervous system (CNS)-associated syndromes. In pediatric populations, frequencies of CNS sequelae occur in 0.1% to 7% of patients. Neurologic illness associated with M. pneumoniae, such as meningitis, encephalitis, polyradiculitis. Guillain-Barre, and stroke have been reported; however, the incidence of M. pneurnoniae-associated organic brain syndrome is rare. We present the case of a 20-year-old midshipman with acute psychosis following resolution of M. pneumoniae pneumonia and review 6 other adult cases found in the literature. M. pneumoniae remains one of the most common causes of respiratory illnesses in the military recruit setting and therefore should always be suspected as an organic cause of mental status changes in young persons such as recruits, cadets, and midshipmen particularly with antecedent respiratory illnesses.

AB Cathodoluminescence real-color imaging and spectroscopy were employed to study the properties of Ga2O3 nanowires grown with different Sn/Ga ratios. The structures grown under Sn-rich conditions show large spectral emission variation, ranging from blue to red, with a green transition zone. Spectral emission changes correlate with changes in the chemical composition and structure found by energy dispersive spectroscopy and electron diffraction. A sharp transition from green to red emission correlates with a phase transition of beta-Ga2O3 to polycrystalline SnO2. The origin of the green emission band is discussed based on ab initio calculation results.

It describes some of the main data assembly centers (Argo and in situ data, altimetry, sea surface temperature) developed during the Global Ocean Data Assimilation Experiment. An overview of other data centers (wind and fluxes, ocean color, sea ice) is also given. Much progress has been achieved over the past 10 years to validate, intercalibrate, and merge altimeter data from multiple satellites. Accuracy and timeliness of products have been improved, and new products have been developed. The same is true for sea surface temperature data through the Global High-Resolution Sea Surface Temperature Pilot Project. A breakthrough in processing, quality control, and assembly for in situ data has also been achieved through the development of the real-time and delayed-mode Argo data system. In situ and remote-sensing data are now systematically and jointly used to calibrate, validate, and monitor over the long term the quality and consistency of the global ocean observing system. Main results are illustrated. There is also a review of the development and use of products that merge in situ and remote-sensing data. Future issues and main prospects are discussed in the conclusion.

ID VISUALIZATION
AB The Global Ocean Data Assimilation Experiment (GODAE [http://www.godae.org]) has spanned a decade of rapid technological development. The ever-increasing volume and diversity of oceanographic data produced by in situ instruments, remote-sensing platforms, and computer simulations have driven the development of a number of innovative technologies that are essential for connecting scientists with the data that they need. This paper gives an overview of the technologies that have been developed and applied in the course of GODAE, which now provide users of oceanographic data with the capability to discover, evaluate, visualize, download, and analyze data from all over the world. The key to this capability is the ability to reduce the inherent complexity of oceanographic data by providing a consistent, harmonized view of the various data products. The challenges of data serving have been addressed over the last 10 years through the cooperative skills and energies of many individuals.

AB During the last 15 years, operational oceanography systems have been developed in several countries around the world. These developments have been fostered primarily by the Global Ocean Data Assimilation Experiment (GODAE), which coordinated these activities, encouraged partnerships, and facilitated constructive competition. This multinational coordination has been very beneficial for the development of operational oceanography. Today, several systems provide routine, real-time ocean analysis, forecast, and reanalysis products. These systems are based on (1) state-of-the-art Ocean General Circulation Model configurations, either global or regional (basin-scale), with resolutions that range from coarse to eddy-resolving, and (2) data assimilation techniques ranging from analysis correction to advanced three- or four-dimensional variational schemes. These systems assimilate altimeter sea level anomalies, sea surface temperature data, and in situ profiles of temperature and salinity, including Argo data. Some systems have implemented downscaling capacities, which consist of embedding higher-resolution local systems in global and basin-scale models (through open boundary exchange of data), especially in coastal regions, where small scale-phenomena are important, and also increasing the spatial resolution for these regional/coastal systems to be able to resolve smaller scales (so-called downscaling). Others have implemented coupling with the atmosphere and/or sea ice. This paper provides a short review of these operational GODAE systems.

ID KALMAN FILTER; MODEL; TEMPERATURE; SALINITY; SMOOTHER
AB Ocean data assimilation has matured to the point that observations are now routinely combined with model forecasts to produce a variety of ocean products. Approaches to ocean data assimilation vary widely both in terms of the sophistication of the method and the observations assimilated, and also in terms of specification of the forecast error covariances, model biases, observation errors, and quality-control procedures. In this paper, we describe some of the ocean data assimilation systems that have been developed within the Global Ocean Data Assimilation Experiment (GODAE) community. We discuss assimilation methods, observations assimilated, and techniques used to specify error covariances. In addition, we describe practical implementation aspects and present analysis performance results for some of the analysis systems. Finally, we describe plans for improving the assimilation systems in the post-GODAE time period beyond 2008.

AB The feasibility of global ocean weather prediction was just emerging as the Global Ocean Data Assimilation Experiment (GODAE) began in 1997. Ocean weather includes phenomena such as meandering currents and fronts, eddies, the surface mixed layer and sea surface temperature (SST), equatorial and coastally trapped waves, upwelling of cold water, and Rossby waves, all influencing ocean variables such as temperature (T), salinity (S), currents, and sea surface height (SSH). Adequate real-time data input, computing power, numerical ocean models, data assimilation capabilities, atmospheric forcing, and bathymetric/boundary constraints are essential to make such prediction possible. The key observing systems and real-time data inputs are SSH from satellite altimetry, satellite and in situ SST T, or T and S profiles (e.g., Argo, TAO/Triton, PIRATA moored array in the Atlantic, bathythermographs), and atmospheric forcing. The ocean models dynamically interpolate data in conjunction with data assimilation, convert atmospheric forcing into oceanic responses, and forecast the ocean weather, applying bathymetric/boundary constraints in the process. The results are substantially influenced by ocean model simulation skill and it is advantageous to use an ocean model that is eddy-resolving (nominally 1/10 degrees or finer), not just eddy-permitting. Because the most abundant ocean observations are satellite surface data, and subsurface data are very sparse in relation to the spatial scales of the mesoscale ocean features that dominate the ocean interior, downward projection of surface data is a key challenge in ocean data assimilation. The need for accurate prediction of ocean features that are inadequately observed, such as mixed layer depth, places a major burden on the ocean model, data assimilation, and atmospheric forcing. The sensitivity of ocean phenomena to atmospheric forcing and the time scale for response affect the time scale for oceanic predictive skill, sensitivity to the initial state versus the atmospheric forcing as a function of forecast length, and thus oceanic data requirements and prediction system design. Outside of surface boundary layers and shallow regions, forecast skill is about one month globally and over many subregions, and is only modestly reduced by using climatological forcing after the end of atmospheric forecasts versus using analysis-quality forcing for the duration. In addition, global ocean prediction systems must demonstrate the ability to provide initial and boundary conditions to nested regional and coastal models that enhance their predictive skill. Demonstrations of feasibility in relation to the preceding phenomena, requirements, and challenges are drawn from the following global and basin-scale ocean prediction systems: BLUElink> (Australia), the HYbrid Coordinate Ocean Model (HYCOM; USA), Mercator (France), Multivariate Ocean Variational Estimation/Meteorological Research Institute Community Ocean Model (MOVE/MRI.COM; Japan), and the Naval Research Laboratory Layered Ocean Model (NLOM; USA).

AB During the Global Ocean Data Assimilation Experiment (GODAE), seven international operational centers participated in a dedicated modeling system intercomparison exercise from February to April 2008. The objectives were: (1) to show GODAE global-ocean and basin-scale forecasting systems of different countries in routine interaction and continuous operation, (2) to assess the quality and perform scientific validation of the ocean analyses and the forecasting performance of each system, and (3) to learn from this exercise in order to increase interoperability and collaboration in real time. The validation methodology has steadily improved through several validation experiments and projects performed within the operational oceanography community. It relies on common approaches and standardization of outputs, with a set of diagnostics based on fully detailed metrics that characterize its strengths and weaknesses, but it also provides error levels for ocean estimates. The ocean forecasting systems provide daily fields of mesoscale water mass distribution and ocean circulation, with an option for sea-ice variations. We present a subset of the intercomparisons performed over different areas, showing general ocean circulation in agreement with known patterns. We also present some accuracy assessments through comparison with observed data.

AB Global ocean forecast systems, developed under the Global Ocean Data Assimilation Experiment (GODAE), are a powerful means of assessing the impact of different components of the Global Ocean Observing System (GOOS). Using a range of analysis tools and approaches, GODAE systems are useful for quantifying the impact of different observation types on the quality of analyses and forecasts. This assessment includes both existing and future observation platforms. Many important conclusions can be drawn from these studies. It is clear that altimeter data are extremely important for constraining mesoscale variability in ocean forecast systems. The number of altimeters is also important. For example, near-real-time applications need data from four altimeters to achieve skill that is similar to systems using data from two altimeters in delayed mode. Another important result is that sea surface temperature is the only observation parameter that adequately monitors ocean properties in coastal regions and shallow seas. Assimilation of Argo data provides a significant, measurable improvement to GODAE systems, and is the only observation platform that provides global-scale information for constraining salinity. The complementary nature of different components of GOOS is now clear and the emergence of new assimilation techniques for observing system evaluation provides the GODAE community with a practical path toward routine GOOS monitoring.

ID OPERATIONAL OCEANOGRAPHY
AB The Global Ocean Data Assimilation Experiment (GODAE) brought together an international group of researchers to address the problem of predicting the ocean environment. GODAE addressed the necessary technological development for data assimilation, which is a critical choke point within the process of providing meaningful information. These efforts brought a significant step forward, and today these technologies are applied operationally in areas of historically strong need. One application is for navies throughout the globe. Navies are now making regular use of oceanographic information forecast by numerical models that are initialized by assimilation of global satellite and in situ data sets. Prior to GODAE, forecast properties were not available operationally, and the information provided to navy operators was typically either climatology or local observations. The ability to forecast the ocean environment has significantly changed how navies operate. Rather than going to a location at a predetermined time and determining whether the environment is suitable to safely conduct a mission, navies can now choose where and when they may operate safely and efficiently to either avoid adverse effects or take advantage of favorable conditions. Several example events over recent years highlight how navies around the world use GODAE forecast information.

AB Sudden tropical cyclone (TC) intensification has been linked with high values of upper ocean heat content contained in mesoscale features, particularly warm ocean eddies, provided that atmospheric conditions are also favorable. Although understanding of air-sea interaction for TCs is evolving, this manuscript summarizes some of the current work being carried out to investigate the role that the upper ocean plays in TC intensification and the use of ocean parameters in forecasting TC intensity.

Rather than attempting an exhaustive synthesis, this article illustrates the progress in coastal ocean modeling and prediction made possible by GODAE, either directly by providing estimates, or more subtly by rendering coastal forecasting more feasible and its applications more obvious.

AB We describe a multistage, stochastic, mixed-integer programming model for planning capacity expansion of production facilities. A scenario tree represents uncertainty in the model; a general mixed-integer program defines the operational submodel at each scenario-tree node, and capacity-expansion decisions link the stages. We apply "variable splitting" to two model variants, and solve those variants using Dantzig-Wolfe decomposition. The Dantzig-Wolfe master problem can have a much stronger linear programming relaxation than is possible without variable splitting, over 700% stronger in one case. The master problem solves easily and tends to yield integer solutions, obviating the need for a full branch-and-price solution procedure. For each scenario-tree node, the decomposition defines a subproblem that may be viewed as a single-period, deterministic, capacity-planning problem. An effective solution procedure results as long as the subproblems solve efficiently, and the procedure incorporates a good "duals stabilization method." We present computational results for a model to plan the capacity expansion of an electricity distribution network in New Zealand, given uncertain future demand. The largest problem we solve to optimality has six stages and 243 scenarios, and corresponds to a deterministic equivalent with a quarter of a million binary variables.

AB Amalgam has successfully been used as a restorative material in dentistry for over a century. It has proven to be a cost-effective, wear-resistant material which, when properly placed, can provide many years of service. However, amalgam's popularity has decreased in recent years due, in part, to patient concerns about its potential for adversely affecting their health. Other reasons for its reduced use include the increased emphasis on more esthetic restorative materials and environmental concerns regarding the amount of mercury discharged into wastewater from dental offices. Controversy persists about amalgam's possible role in causing health problems due to its release of mercury. Although conclusive evidence is lacking that directly correlates amalgam with adverse health effects, clinicians should remain knowledgeable about mercury release from amalgam in order to intelligently address their patients' concerns. This article reviews the latest published scientific literature to provide this information.

ID CONDUCTIVITY
AB It is commonly known that underwater imaging is hindered by both absorption and scattering by particles of various origins. However, evidence also indicates that the turbulence in natural underwater environments can cause severe image-quality degradation. A model is presented to include the effects of both particle and turbulence on underwater optical imaging through optical transfer functions to help quantify the limiting factors under different circumstances. The model utilizes Kolmogorov-type index of refraction power spectra found in the ocean, along with field examples, to demonstrate that optical turbulence can limit imaging resolution by affecting high spatial frequencies. The effects of the path radiance are also discussed.

AB P>Traditional vaccine technologies have resulted in an impressive array of efficacious vaccines against a variety of infectious agents. However, several potentially deadly pathogens, including retroviruses and parasites, have proven less amenable to the application of traditional vaccine platforms, indicating the need for new approaches. Viral vectors represent an attractive way to deliver and present vaccine antigens that may offer advantages over traditional platforms. Due to their ability to induce strong cell-mediated immunity (CMI) in addition to antibodies, viral vectors may be suitable for infectious agents, such as malaria parasites, where potent CMI is required for protection. Poxvirus-vectored malaria vaccines have been the most extensively studied in the clinic, achieving significant reductions in liver-stage parasite burden. More recently, adenovirus-vectored malaria vaccines have entered clinical testing. The most promising approach - heterologous prime-boost regimens, in which different viral vectors are sequentially paired with each other or with DNA or recombinant protein vaccines - is now being explored, and could provide high-grade protection, if findings in animal models are translatable to humans. Significant barriers remain, however, such as pre-existing immunity to the vector particle and an unexplained safety signal observed in one trial suggesting an increased risk of HIV acquisition in volunteers with pre-existing immunity to the vector.

nanojunctions with spin-active interfaces
SO PHYSICAL REVIEW B

ID FERROMAGNET STRUCTURES
AB We study triplet pairing correlations induced in an SFS trilayer (where F is a ferromagnet and S an ordinary s-wave superconductor) by spin-flip scattering at the interfaces, via the derivation and self-consistent solution of the appropriate Bogoliubov-de Gennes equations in the clean limit. We find that the spin-flip scattering generates m = +/- 1 triplet correlations, odd in time and study the general spatial behavior of these and of m = 0 correlations as a function of position and of spin-flip strength, H(spin), concentrating on the case where the ferromagnet is half-metallic. For certain values of H(spin), the triplet correlations pervade the magnetic layer and can penetrate deeply into the superconductor. The behavior we find depends very strongly on whether the singlet order parameter is in the 0 or pi state, which must in turn be determined self-consistently. We also present results for the density of states (DOS) and for the local magnetization, which, due to spin-flip processes, is not in general aligned with the magnetization of the half-metal, and near the interfaces, rotates as a function of position and H(spin). The average DOS in both F and S is shown to exhibit various subgap bound states positioned at energies that depend strongly on the particular junction state and the spin-flip scattering strength.

SO PHYSICAL REVIEW B

ID PAIRING SYMMETRY; MAGNETIC ORDER; NMR
AB We investigate the effect of a spin-density wave (SDW) on s(+/-) superconductivity in Fe-based superconductors. We show that, contrary to the common wisdom, no nodes open at the new, reconnected Fermi surfaces when the hole and electron pockets fold down in the SDW state, despite the fact that the s(+/-) gap changes sign between the two pockets. Instead, the order parameter preserves its sign along the newly formed Fermi surfaces. The familiar experimental signatures of an s(+/-) symmetry are still preserved, although they appear in a mathematically different way. For a regular s case (s(++)) the nodes do appear in the SDW state. This distinction suggests a specific way to experimentally separate an s(+/-) state from a regular s in the pnictides. We argue that recently published thermal-conductivity data in the coexisting state are consistent with the s(+/-), but not the s(++) state.

AB A description of spin Faraday rotation, Kerr rotation and ellipticity signals for single-and multilayer ensembles of singly charged quantum dots (QDs) is developed. The microscopic theory considers both the single pump-pulse excitation and the effect of a train of such pulses, which in the case of long resident-electron spin coherence time leads to a stationary distribution of the electron spin polarization. The calculations performed for single-color and two-color pump-probe setups show that the three experimental techniques: Faraday rotation, Kerr rotation, and ellipticity measurements provide complementary information about an inhomogeneous ensemble of QDs. The microscopic theory developed for a three-dimensional ensemble of QDs is shown to agree with the phenomenological description of these effects. The typical time-dependent traces of pump-probe Faraday rotation, Kerr rotation and ellipticity signals are calculated for various experimental conditions.

ID CHAOTIC SYSTEMS; SYNCHRONIZATION; NETWORKS
AB Master-stability functions (MSFs) are fundamental to the study of synchronization in complex dynamical systems. For example, for a coupled oscillator network, a necessary condition for synchronization to occur is that the MSF at the corresponding normalized coupling parameters be negative. To understand the typical behaviors of the MSF for various chaotic oscillators is key to predicting the collective dynamics of a network of these oscillators. We address this issue by examining, systematically, MSFs for known chaotic oscillators. Our computations and analysis indicate that it is generic for MSFs being negative in a finite interval of a normalized coupling parameter. A general scheme is proposed to classify the typical behaviors of MSFs into four categories. These results are verified by direct simulations of synchronous dynamics on networks of actual coupled oscillators.

TI Limiting current enhancements for a relativistic electron beam

SO PHYSICS OF PLASMAS
LA English
DT Article
ID TUBES
AB An investigation of the space-charge-limited (SCL) currents for un-neutralized relativistic electron beams drifting through an infinitely long dielectrically lined coaxial cylindrical structure with a biased inner conductor is presented. To begin, an approximate limiting current expression is developed for an un-neutralized finite-width relativistic electron beam drifting through a biased coaxial cylindrical structure, which contains no dielectric liner. The SCL currents are then numerically calculated and compared to the approximation and it is shown that there is good agreement between the two. Building on this, the SCL currents are then numerically calculated when a dielectric liner, which encloses the finite-width electron beam, is present. It is shown that when a dielectric liner is present, there is a point at which increases in the SCL currents saturate and increasing the relative dielectric constant provides no additional increase in the expected SCL currents. In addition, it is demonstrated that the dielectric liner, in conjunction with the biased inner conductor, provides significant SCL current enhancements when compared to a system with no dielectric liner and no biased inner conductor. Finally, the possibility of dielectric breakdown is addressed as well as the amount of accumulated charge at the vacuum-dielectric interface. [doi: 10.1063/1.3234258]

ID FAST-ELECTRON TRANSPORT; IN-CELL SIMULATIONS; GENERATION; PULSE
AB The ionization dynamics of a thin aluminum foil irradiated by an ultrashort high-intensity laser is investigated with a two-dimensional relativistic electromagnetic particle-in-cell model, which includes optical field and collisional ionizations. The spatio-temporal characteristics of the ion charge and electron density have been studied for peak laser intensities between 10(22) and 10(24) W m(-2) and a laser pulse duration of 80 fs. A series of ionization waves, launched near the front target surface, propagate through the target with a velocity of about two tenths the speed of light. In the pre-plasma region the aluminum is almost fully ionized due to optical field ionization, while in the bulk of the target the collisional ionization is more efficient. The ion charge in the bulk is a result of a complex sequence of events, the major role in which is played by the deposition of laser energy in the system and its distribution among the various degrees of freedom.

AB The prediction of surface drift of floating objects is an important task, with applications such as marine transport, pollutant dispersion, and search-and-rescue activities. But forecasting even the drift of surface waters is very challenging, because it depends on complex interactions of currents driven by the wind, the wave field and the general prevailing circulation. Furthermore, although each of those can be forecasted by deterministic models, the latter all suffer from limitations, resulting in imperfect predictions. In the present study, we try and predict the drift of two buoys launched during the DART06 (Dynamics of the Adriatic sea in Real-Time 2006) and MREA07 (Maritime Rapid Environmental Assessment 2007) sea trials, using the so-called hyper-ensemble technique: different models are combined in order to minimize departure from independent observations during a training period; the obtained combination is then used in forecasting mode. We review and try out different hyper-ensemble techniques, such as the simple ensemble mean, least-squares weighted linear combinations, and techniques based on data assimilation, which dynamically update the model's weights in the combination when new observations become available. We show that the latter methods alleviate the need of fixing the training length a priori, as older information is automatically discarded.
When the forecast period is relatively short (12 h), the discussed methods lead to much smaller forecasting errors compared with individual models (at least three times smaller), with the dynamic methods leading to the best results. When many models are available, errors can be further reduced by removing colinearities between them by performing a principal component analysis. At the same time, this reduces the amount of weights to be determined.
In complex environments when meso- and smaller scale eddy activity is strong, such as the Ligurian Sea, the skill of individual models may vary over time periods smaller than the forecasting period (e.g. when the latter is 36 h). In these cases, a simpler method such as a fixed linear combination or a simple ensemble mean may lead to the smallest forecast errors. In environments where surface currents have strong mean-kinetic energies (e.g. the Western Adriatic Current), dynamic methods can be particularly successful in predicting the drift of surface waters. In any case, the dynamic hyper-ensemble methods allow to estimate a characteristic time during which the model weights are more or less stable, which allows predicting how long the obtained combination will be valid in forecasting mode, and hence to choose which hyper-ensemble method one should use.

AB Hyperspectral imaging data have been collected with different types of imaging spectrometers from aircraft and satellite platforms since the mid-1980s. Because the solar radiation on the sun-surface-sensor path in the 0.4-2.5 mu m visible and near-IR spectral regions is subject to absorption and scattering by atmospheric gases and aerosols, the hyperspectral imaging data contains atmospheric effects. In order to use hyperspectral imaging data for quantitative remote sensing of land surfaces and ocean color, the atmospheric effects must be removed. Over the years, atmospheric correction algorithms have evolved from the earlier empirical line method and the flat field method to more recent methods based on rigorous radiative transfer modeling approaches. Here, a review of hyperspectral atmospheric correction techniques is presented. Issues related to spectral smoothing are discussed. Suggestions for improvements to the present atmospheric correction algorithms, mainly the addition of a module for modeling atmospheric nitrogen dioxide absorption effects in the visible, are given.

AB Lung contusion is a common problem from blunt chest trauma caused by mechanical forces and by exposure to blast overpressure, often with fatal consequences. Lung contusion is also a risk factor for the development of pneumonia, severe clinical acute lung injury (ALI), and acute respiratory distress syndrome (ARDS). Infiltrating neutrophils are considered to be central mediators of lung injuries after blunt trauma. Recent studies have demonstrated that antioxidants reduced pulmonary inflammation in different models of lung damage. This study examined the effect of antioxidant N-acetylcysteine amide (NACA) on the progression of lung inflammation after exposure to a moderate level of blast overpressure (140 kPa). Rats were administered with NACA (i.p. 100 mg/kg) or placebo (PBS) 30, 60 min and 24 h after exposure. Nonblasted sham-injected animals served as controls. Neutrophil infiltration measured by myeloperoxidase (MPO) activity in the lung was significantly increased at 2 days after blast and returned to controls at 8 days. This increase corresponded with activation of integrin CD11b mRNA and lung inflammatory chemokine mRNA expression; macrophage inflammatory protein-1 (MIP-1), monocyte chemotactic peptide-1 (MCP-1), and cytokine-induced neutrophil chemoattractant-1 (CINC-1). At 8 days, all inflammatory mediators returned to control levels. In addition, expression of heme oxygenase-1 (HO-1) mRNA increased at 2 days after exposure. No changes were detected in the lung manganase superoxide dismutase (MnSOD) or glutathione reductase (GR) mRNA expression after blast. N-Acetylcysteine amide significantly reduced infiltration of neutrophils and CD11b mRNA activation in lungs, and completely blocked activation of MIP-1, MCP-1 and CINC-1 mRNA. The relatively higher inhibition of chemokine mRNAs compared with reduction in MPO activity and CD11b is in accordance with an antioxidant effect of NACA on reactive oxygen species (ROS) accumulation, rather than by an effect on neutrophil sequestration. The inhibition of HO-1 mRNA activation after blast was likely also related to the drug antioxidant effect.

By coherent pump-probe spectroscopy, we demonstrate the Autler-Townes splitting and Mollow absorption spectrum in a single neutral quantum dot. Furthermore, we also show the typical Mollow absorption spectrum by driving a singly charged quantum dot in a strong optical coupling regime. Our results show all the typical features of an isolated atomic system driven by a strong optical field, such as the AC stark effect, Rabi side bands and optical gain effect, which indicate that both neutral and charged quantum dots maintain the discrete energy level states even at high optical field strengths.

Objective. To review the management of a neurologically intact patient with complete cervical spondyloptosis with particular attention to the role and timing of closed preoperative cervical traction and subsequent stabilization.
Summary of Background Data. Traumatic cervical spondyloptosis is typically associated with complete and irreversible spinal cord injury. In these patients, cervical traction can be implemented to restore anatomic alignment in preparation for stabilization with minimal consequence. When a patient presents neurologically intact, the management becomes more complicated. Preservation of function and restoration of anatomic alignment collectively represent the goals of therapy. The current literature does not clearly define the role of cervical traction in such cases.
Methods. A patient with traumatic cervical spondyloptosis at the C7-T1 level presented to our institution and was found to be neurologically intact. Computed tomography demonstrated complete spondyloptosis with multiple fractures through the posterior elements.
Results. The spondyloptosis was reduced with closed cervical traction and underwent anterior and posterior instrumented stabilization. No new deficit occurred in the patient after reduction.
Conclusion. Fractures of the posterior elements functionally decompress the spinal canal and thereby allow for cervical traction to be safely implemented in patients with spondyloptosis. Safe restoration of anatomic alignment in the neurologically intact spondyloptotic patient is crucial to minimize the extent of surgical stabilization and create a long-term stable construct of the fracture dislocation.

AB Aerosol samples were collected and cloud condensation nuclei (CCN) concentrations at five supersaturations were measured along and off the central California coast within the cloud-topped, marine boundary layer from aircraft flights during August 2007. Receptor modelling has been applied to estimate the natural versus anthropogenic source contribution of cloud condensation nuclei in this region, a region of climatically important marine stratocumulus. The results suggest that anthropogenic CCN accounted for about 50% of the CCN active at 0.3% supersaturation in this region during the measurement period.

AB Four known electronically diverse cobalt(II) acetylacetonate derivatives were synthesized by replacement of the acetylacetonate methyl groups with combinations of tert-butyl, ethoxy, and trifluoromethyl groups in order to study the effect of catalyst electronic properties on the reaction rate and product yield of the cobalt-catalyzed reaction between haloalkenes and butylzinc iodide. Infrared spectroscopy of these compounds showed an increase in the CO stretching frequency as the ligand substituents became more electron withdrawing. These compounds, in addition to cobalt(II) acetylacetonate itself, were evaluated as catalysts for the coupling reaction between (E)-1-iodo-1-octene and butylzinc iodide to form (E)-5-dodecene. Faster reaction rates were observed and higher yields of 5-dodecene were produced when catalysts containing electron-donating ligands were employed. Side reactions, including the homocoupling of 1-iodo-1-octene to produce 7,9-hexadecadiene, were also observed under the reported reaction conditions. The rate of side-product formation was more competitive with the rate of the cross-coupling reaction when slower, electron-deficient catalysts were employed.

ID QSARS
AB Quantitative structural activity relationship (QSAR) models are receiving wide use because of new regulations and public scrutiny regarding new compounds entered into commerce. Accordingly, the US Department of Defense (DoD) supported this study to evaluate QSAR modeling for energetic compounds. Four compounds proposed to replace ammonium perchlorate were examined: ammonium di(nitramido)amine (ADNA); 1,3,5,5-tetranitrohexahydropyrimidine (DNNC); 1,3,3,5,7,7-hexanitro-1,5-diazacyclooctane (HCO); and diammonium di(nitramido)dinitroethylene (ADNDNE). Currently used compounds were evaluated as analogues for those under development. Ammonium dinitramide (ADN) was the analogue for ADNA; hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) for DNNC; octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) for HCO; and 1,1-diamino-2,2-dinitroethene (FOX-7) for ADNDNE. QSAR analysis was performed with the US Environmental Protection Agency's Estimation Program Interface (EPI) Suite (TM). The comparison of model estimates to literature values ranged from good-to-poor. Results suggested the proposed replacement compounds have low aquatic toxicities and little potential to bioaccummulate, but the uncertainty in the predictions indicates QSAR modeling with EPI Suite (TM) is only useful for qualitative assessments of these proposed energetic compounds.

AB Friction stir welds in Al 5456 were analyzed to determine their microstructure, mechanical properties, and corrosion behavior as a function of position across the transverse cross-section of the weld. The microstructural evolution that occurred in each weld-affected region was correlated to the properties of those regions to determine the microstructural basis for the observed tensile, fatigue, and corrosion properties. In particular, the effects of weld-induced deformation recovery (both in terms of reduced dislocation density and its implications on solute content and precipitation), grain growth, and precipitate evolutions will be discussed.

AB We report K/pi fluctuations from Au+Au collisions at s(NN)=19.6, 62.4, 130, and 200 GeV using the STAR detector at the Relativistic Heavy Ion Collider. K/pi fluctuations in central collisions show little dependence on incident energy and are on the same order as those from NA49 at the Super Proton Synchrotron in central Pb+Pb collisions at s(NN)=12.3 and 17.3 GeV. We report results for the collision centrality dependence of K/pi fluctuations and results for charge-separated fluctuations. We observe that the K/pi fluctuations scale with the charged particle multiplicity density.

TI Amplifying the Pacific Climate System Response to a Small 11-Year Solar
Cycle Forcing
SO SCIENCE
LA English
DT Article
ID VARIABILITY; TEMPERATURE; IRRADIANCE; REGION; PEAKS
AB One of the mysteries regarding Earth's climate system response to variations in solar output is how the relatively small fluctuations of the 11-year solar cycle can produce the magnitude of the observed climate signals in the tropical Pacific associated with such solar variability. Two mechanisms, the top-down stratospheric response of ozone to fluctuations of shortwave solar forcing and the bottom-up coupled ocean-atmosphere surface response, are included in versions of three global climate models, with either mechanism acting alone or both acting together. We show that the two mechanisms act together to enhance the climatological off-equatorial tropical precipitation maxima in the Pacific, lower the eastern equatorial Pacific sea surface temperatures during peaks in the 11-year solar cycle, and reduce low-latitude clouds to amplify the solar forcing at the surface.

TI Comparisons of monthly mean 10 m wind speeds from satellites and NWP
products over the global ocean

AB The accuracy of wind speed at 10 m above the sea surface from two satellite and three numerical weather prediction (NWP) products is investigated over the global ocean. Rain-free equivalent neutral winds from the Quick Scatterometer (QuikSCAT) are converted to stability-dependent winds to be consistent with those from NWP products and are taken as truth in comparisons to winds from other products. Quantitative statistical analyses presented at each grid point over the global ocean reveal that monthly winds from NWP products have almost perfect skill relative to those from QuikSCAT winds during the 3-year common period (September 1999 to August 2002). Exceptions occur in tropical regions and high southern latitudes. Wind speeds adjusted to 10 m at many moored buoys located in different regions of the global ocean further confirm the accuracy of monthly NWP winds, giving RMS difference of 1.0 m s(-1) based on 1281 monthlong time series. The satellite-based QuikSCAT winds agree with buoy winds relatively better than NWP products. While there is good agreement among wind products on monthly timescales, large differences (>3 m s(-1) and more) in NWP winds are found in comparison to QuikSCAT winds on shorter time intervals at high latitudes. Daily means of sensible and latent heat fluxes based on NWP winds can therefore differ as much as 100 W m(-2) in comparison to those based on QuikSCAT winds. In general, NWP wind-based sensible and latent heat fluxes are more similar to their QuikSCAT wind-based counterparts in tropical regions and midlatitudes.

AB We applied the NRL-tight-binding method in static and molecular dynamics simulations for determining the electronic and dynamic properties of the binary Nb-Mo and Cu-Zr systems. The tight-binding (TB) Hamiltonians were determined by least-square fits to databases obtained by density functional theory calculations that include the band structures and the total energies of the pure elements and the B2(CsCl) structures for the alloys. In previous work we established that the NRL-TB scheme gives accurate predictions of many properties of the pure elements. In this work we present calculations referring to the total energy for various compositions, the band structure, the vacancy formation energies and the mean-squared displacements of NbMo and CuZr in the CsCl structure.

TI Impact of modeled versus satellite measured tropical precipitation on

SO GEOPHYSICAL RESEARCH LETTERS

ID CLIMATE MODELS; SCHEME; CONVECTION; PRODUCTS
AB Aerosol and climate models are dependent on the parameterizations of the underlying meteorological model. Precipitation schemes in global meteorological models are designed to close the regional water budget, without concern for representative wet removal. By substituting numerical model precipitation for a multi-satellite precipitation dataset, we demonstrate the impact of modeled versus satellite-derived precipitation on aerosol optical depth (AOD) in the Navy Aerosol Analysis and Prediction System (NAAPS). The model and satellite-derived precipitation are shown to have similar precipitation amounts, but the precipitation area from the model is about twice that in the satellite data. The resulting difference in scavenging results in an increase in mid-visible AOD of about 20-200% in parts of Southeast Asia and South America during the burning seasons (or 0.1-0.2 in AOD). This suggests that care must be taken when combining free-running model and remote sensing data to evaluate smoke-cloud interactions or to estimate source magnitudes. Citation: Xian, P., J. S.

AB In this work we demonstrate a method to derive the concentration of aerosol components from the spectral measurements of AOD (aerosol optical depth) and single scattering albedo along with their size distribution and extinction profile available from AERONET (Aerosol Robotic Network) and MPLNET (Micro-pulse Lidar Network) stations. The technique involves finding the best combination of aerosol concentration by minimizing differences between measured and calculated values of aerosol parameters such as AOD, single scattering albedo, and size distribution. We applied this technique over selected sites in three different regions of the United States (West coast, Great Plains, and North-East). Our results are then compared with the measured concentration of aerosol components available from IMPROVE (Interagency Monitoring of Protected Visual Environments) and EPA (Environmental Protection Agency) network, as well as two different versions of the GFDL (Geophysical Fluid Dynamics Laboratory) General Circulation Model AM2 with online and offline aerosols. In general, concentrations retrieved by our technique compare well with the ground-based measurements, but there are some discrepancies possibly due to the inherent differences in temporal and spatial scales of data averaging or some of the assumptions made in our study. Over continental North America, the online version of AM2 appears to overestimate sulfate concentration approximately by a factor of two and underestimate organic carbon by nearly the same amount. Results of our sensitivity study show that the errors in the retrieval of black carbon and sulfate concentrations could be as high as 100% when there is a large bias of similar to 0.05 in the reference values of single scattering albedo under high AOD (>= 0.5 0.44 mu m) conditions. Knowledge on the vertical distribution of aerosols is crucial for an accurate retrieval of surface concentration of aerosols. We also determine the composition and concentration of elevated aerosol layers using this technique.

AB Experimental study of a shock-decelerated ablation front is reported. A planar solid plastic target is accelerated by a laser across a vacuum gap and collides with a lower-density plastic foam layer. While the target is accelerated, a fast Rayleigh-Taylor (RT) growth of the seeded single-mode perturbation at the ablation front is observed. After the collision, the velocity of the ablation front is seen to remain constant. The reshock quenches the RT growth but does not trigger any Richtmyer-Meshkov growth at the ablation front, which is shown to be consistent with both theory and simulations.

AB We have fabricated hybrid magnetic complexes from V atoms and tetracyanoethylene ligands via atomic manipulation with a cryogenic scanning tunneling microscope. Using tunneling spectroscopy we observe spin-polarized molecular orbitals as well as Kondo behavior. For complexes having two V atoms, the Kondo behavior can be quenched for different molecular arrangements, even as the spin-polarized orbitals remain unchanged. This is explained by variable spin-spin (i.e., V-V) ferromagnetic coupling through a single tetracyanoethylene (TCNE) molecule, as supported by density functional calculations.

AB We present a spectral analysis of the Far Ultraviolet Spectroscopic Explorer ( FUSE) spectra of eight high-declination dwarf novae ( DNs) obtained from a Cycle 7 FUSE survey. These DN systems have not been previously studied in the UV and little is known about their white dwarfs ( WDs) or accretion disks. We carry out the spectral analysis of the FUSE data using synthetic spectra generated with the codes TLUSTY and SYNSPEC. For two faint objects ( AQ Men and V433 Ara) we can only assess a lower limit for the WD temperature or mass accretion rate. NSV 10934 was caught in a quiescent state and its spectrum is consistent with a low-mass accretion rate disk. For five objects ( HP Nor, DT Aps, AM Cas, FO Per, and ES Dra), we obtain WD temperatures between 34,000 K and 40,000 K and/or mass accretion rates consistent with intermediate to outburst states. These temperatures reflect the heating of the WD due to on-going accretion and are similar to the temperatures of other DNs observed on the rise to, and in decline from outburst. The WD temperatures we obtain should therefore be considered as upper limits, and it is likely that during quiescence AM Cas, FO Per, and ES Dra are near the average WD T(eff) for catalcysmic variables above the period gap (similar to 30,000 K), similar to U Gem, SS Aur, and RX And.

AB The observed faintness of infrared fine-structure line emission along with the warm far-infrared ( FIR) colors of ultraluminous infrared galaxies ( ULIRGs) is a long-standing problem. In this work, we calculate the line and continuum properties of a cloud exposed to an active galactic nucleus ( AGN) and starburst spectral energy distribution. We use an integrated modeling approach, predicting the spectrum of ionized, atomic, and molecular environments in pressure equilibrium. We find that the effects of high ratios of impinging ionizing radiation density to particle density (i.e., high-ionization parameters, or U) can reproduce many ULIRG observational characteristics. Physically, as U increases, the fraction of UV photons absorbed by dust increases, corresponding to fewer photons available to photoionize and heat the gas, producing what is known as a "dust-bounded" nebula. We show that high-U effects can explain the "[C II] deficit," the similar to 1 dex drop in the [ C II] 158 mu m/FIR ratio seen in ULIRGs when compared with starburst or normal galaxies. Additionally, by increasing U through increasing the ionizing photon flux, warmer dust and thus higher IRAS F( 60 mu m)/F( 100 mu m) ratios result. High-U effects also predict an increase in [ O I] 63 mu m/[ C II] 158 mu m and a gradual decline in [ O III] 88 mu m/FIR, similar to the magnitude of the trends observed, and yield a reasonable fit to [ Ne V] 14 mu m/FIR ratio AGN observations.

TI FERMI LAT OBSERVATIONS OF LS I+61 degrees 303: FIRST DETECTION OF AN

AB This Letter presents the first results from the observations of LS I + 61 degrees 303 using Large Area Telescope data from the Fermi Gamma-Ray Space Telescope between 2008 August and 2009 March. Our results indicate variability that is consistent with the binary period, with the emission being modulated at 26.6 +/- 0.5 days. This constitutes the first detection of orbital periodicity in high-energy gamma rays (20 MeV-100 GeV, HE). The light curve is characterized by a broad peak after periastron, as well as a smaller peak just before apastron. The spectrum is best represented by a power law with an exponential cutoff, yielding an overall flux above 100 MeV of 0.82 +/- 0.03(stat) +/- 0.07(syst) 10(-6) ph cm(-2) s(-1), with a cutoff at 6.3 +/- 1.1(stat) +/- 0.4(syst) GeV and photon index Gamma = 2.21 +/- 0.04(stat) +/- 0.06(syst). There is no significant spectral change with orbital phase. The phase of maximum emission, close to periastron, hints at inverse Compton scattering as the main radiation mechanism. However, previous very high-energy gamma ray (>100 GeV, VHE) observations by MAGIC and VERITAS show peak emission close to apastron. This and the energy cutoff seen with Fermi suggest that the link between HE and VHE gamma rays is nontrivial.

AB In the summer of 2001, a coastal ocean measurement program in the southeastern portion of San Pedro Bay, CA, was designed and carried out. One aim of the program was to determine the strength and effectiveness of local cross-shelf transport processes. A particular objective was to assess the ability of semidiurnal internal tidal currents to move suspended material a net distance a cross the shelf. Hence, a dense array of moorings was deployed across the shelf to monitor the transport patterns associated with fluctuations in currents, temperature and salinity. An associated hydrographic program periodically monitored synoptic changes in the spatial patterns of temperature, salinity, nutrients and bacteria. This set of measurements show that a series of energetic internal tide scan, but do not always, transport subthermocline water, dissolved and suspended material from the middle of the shelf into the surfzone. Effective cross-shelf transport occurs only when (1) internal tides at the shelf break are strong and (2) subtidal currents flow strongly down coast. The subtidal down coast flow causes isotherms to tilt upward toward the coast, which allows energetic, nonlinear internal tidal currents to carry subthermocline waters into the surfzone. During these events, which may last for several days, the transported water remains in the surfzone until the internal tidal current pulses and/or the down coast subtidal currents disappear. This nonlinear internal tide cross-shelf transport process was capable of carrying water and the associated suspended or dissolved material from the mid-shelf into the surfzone, but there were no observation of transport from the shelf break into the surfzone. Dissolved nutrients and suspended particulates (such as phytoplankton) transported from the mid-shelf into the near shore region by nonlinear internal tides may contribute to near shore algal blooms, including harmful algal blooms that occur off local beaches.

AB Magnetic and structural characteristics were investigated for the nanoparticles of Fe5Si3 grown by a carbon-mediated, kinetically controlled pyrolysis of a thermosetted ferrocenylsiloxane polymeric network. Kinetics of the pyrolysis determined the volume fraction of the crystallographic phase of Fe5Si3 or bcc-Fe that was formed. Nanoparticles of Fe5Si3 were formed during pyrolysis of the network to 1000 degrees C at 10 degrees C/min. and silicon-doped bcc-Fe nanoparticles resulted when the network was ramped to 1000 degrees C at a slower rate of I degrees C/min. Transmission electron microscopy and X-ray diffraction studies revealed that Fe5Si3 nanoparticles were contained in carbon nanocapsules, and the bcc-Fe nanoparticles were associated with linear carbon fibers, all Outcome of the distinct interfacial energies, of the Fe-Si growth phase and carbon surface at the two pyrolysis rates. Fe5Si3 nanoparticles were found to be ferromagnetic with a Curie temperature of similar to 375 K by magnetic measurements.

AB This work was motivated by ostensibly contradictory results from different groups regarding the effect of pressure on the fragility of glycerol. We present new experimental data for an intermediate pressure regime showing that the fragility increases with pressure up to about 1.8 GPa, becoming invariant at higher pressures. There is no discrepancy among the various literature data taken in toto. The behavior of glycerol is quite distinct from that of normal liquids, a result of its substantial hydrogen bonding.

AB A reversible elastic instability was observed in PZN-0.06PT high coupling single crystals when subjected to uniaxial compressions similar to those used in sound projectors. The strain magnitude at the onset of the instability supported a free energy prediction of a ferroelectric rhombohedral (F(R))-ferroelectric orthorhombic (F(O)) phase transition. The thermal response of the normalized phase transition strain is in a good agreement with model calculation. A dc bias field drastically enhanced the crystal stability under compression. dc bias and compressive stress levels that are required for their stable operation in sound projectors have been deduced and will be presented.

AB Geobacter sulfurreducens produces current densities in microbial fuel cells that are among the highest known for pure cultures. The possibility of adapting this organism to produce even higher current densities was evaluated. A system in which a graphite anode was poised at -400 mV (versus Ag/AgCl) was inoculated with the wild-type strain of G. sulfurreducens, strain DL-1. An isolate, designated strain KN400, was recovered from the biofilm after 5 months of growth on the electrode. KN400 was much more effective in current production than strain DL-1. This was apparent with anodes poised at -400 mV, as well as in systems run in true fuel cell mode. KN400 had current (7.6 A/m(2)) and power (3.9 W/m(2)) densities that respectively were substantially higher than those of DL1 (1.4 A/m(2) and 0.5 W/m(2)). On a per cell basis KN400 was more effective in current production than DL1. requiring thinner biofilms to make equivalent current. The enhanced capacity for current production in KN400 was associated with a greater abundance of electrically conductive microbial nanowires than DL1 and lower internal resistance (0.015 versus 0.130 Omega/m(2)) and mass transfer limitation in KN400 fuel cells. KN400 produced flagella, whereas DL1 does not. Surprisingly, KN400 had much less outer-surface c-type cytochromes than DL1. KN400 also had a greater propensity to form biofilms on glass or graphite than DL1, even when growing with the soluble electron acceptor, fumarate. These results demonstrate that it is possible to enhance the ability of microorganisms to electrochemically interact with electrodes with the appropriate selective pressure and that improved current production is associated with clear differences in the properties of the outer surface of the cell that may provide insights into the mechanisms for microbe-electrode interactions.

ID PREDICTION
AB Reliable forecasts of climate change in the immediate future are difficult, especially on regional scales, where natural climate variations may amplify or mitigate anthropogenic warming in ways that numerical models capture poorly. By decomposing recent observed surface temperatures into components associated with ENSO, volcanic and solar activity, and anthropogenic influences, we anticipate global and regional changes in the next two decades. From 2009 to 2014, projected rises in anthropogenic influences and solar irradiance will increase global surface temperature 0.15 +/- 0.03 degrees C, at a rate 50% greater than predicted by IPCC. But as a result of declining solar activity in the subsequent five years, average temperature in 2019 is only 0.03 +/- 0.01 degrees C warmer than in 2014. This lack of overall warming is analogous to the period from 2002 to 2008 when decreasing solar irradiance also countered much of the anthropogenic warming. We further illustrate how a major volcanic eruption and a super ENSO would modify our global and regional temperature projections. Citation: Lean, J.L., and D. H.

TI Recombination-induced stacking fault degradation of 4H-SiC
merged-PiN-Schottky diodes
SO JOURNAL OF APPLIED PHYSICS
LA English
DT Article
AB The increase in the forward voltage drop observed in 4H-SiC bipolar devices due to recombination-induced stacking fault (SF) creation and expansion has been widely discussed in the literature. It was long believed that the deleterious effect of these defects was limited to bipolar devices. Recent reports point to similar degradation in 4H-SiC DMOSFETs, a primarily unipolar device, which was thought to be SF-related. Here we report similar degradation of both unipolar and bipolar operation of merged-PiN-Schottky diodes, a hybrid device capable of both unipolar and bipolar operation. Furthermore, we report on the observation of the temperature-mediation of this degradation and the observation of the current-induced recovery phenomenon. These observations leave little doubt that this degradation is SF-induced and that if SFs are present, that they will adversely affect both bipolar and unipolar characteristics.

AB In an effort to develop a more versatile creeping biocide that is capable of self-spreading and self-decontaminating of pathogenic bacteria, we report the development of two new homologous series of hybrid PDMS molecules. These oligomers were synthesized with terminal quaternary ammonium functionalities bearing variable length oxyethylene moieties. It is shown that the ionic interaction of the ammonium groups with the surface onto which it spreads can be tempered by the oxyethylene segments through close association of the polar chains with the cationic centers within the hydrophobic PDMS environment, thereby promoting self-spreading of the molecule. Once the compounds spread to a humid environment, the oxyethylene chains "blossom" and subsequently expose the biocidal centers, at which point, function as broad spectrum versatile antimicrobials. While biological evaluation showed antimicrobial activity against both Gram-positive and Gram-negative bacteria for all samples, one series was found to be much more effective due to lower steric hindrance surrounding the biocidal cationic termini. However, this increased exposure of the cationic center also altered the physical properties of the compounds except those isolated as a waxy solid. Self-spreading abilities with increasing oxyethylene chain length correlating to a decreasing spread rate. The decontaminating ability of the two most active compounds was demonstrated by allowing samples to spread to pools of water contaminated with S, aureus, yielding log reductions as high as 5.7 in less than two hours without external influences.

TI Andreev Spectra and Subgap Bound States in Multiband Superconductors
SO PHYSICAL REVIEW LETTERS

ID REFLECTION SPECTROSCOPY; POINT; ENHANCEMENT; JUNCTIONS
AB A theory of Andreev conductance is formulated for junctions involving normal metals (N) and multiband superconductors (S) and applied to the case of superconductors with nodeless extended s(+)-wave order parameter symmetry, as possibly realized in the recently discovered ferropnictides. We find qualitative differences from tunneling into s-wave or d-wave superconductors that may help to identify such a state. First, interband interference leads to a suppression of Andreev reflection in the case of a highly transparent N/S interface and to a current deficit in the tunneling regime. Second, surface bound states may appear, both at zero and at nonzero energies.

AB Pulsars are rapidly rotating, highly magnetized neutron stars emitting radiation across the electromagnetic spectrum. Although there are more than 1800 known radio pulsars, until recently only seven were observed to pulse in gamma rays, and these were all discovered at other wavelengths. The Fermi Large Area Telescope (LAT) makes it possible to pinpoint neutron stars through their gamma-ray pulsations. We report the detection of 16 gamma-ray pulsars in blind frequency searches using the LAT. Most of these pulsars are coincident with previously unidentified gamma-ray sources, and many are associated with supernova remnants. Direct detection of gamma-ray pulsars enables studies of emission mechanisms, population statistics, and the energetics of pulsar wind nebulae and supernova remnants.

AB We report the detection of gamma-ray emissions above 200 megaelectron volts at a significance level of 17 sigma from the globular cluster 47 Tucanae, using data obtained with the Large Area Telescope onboard the Fermi Gamma-ray Space Telescope. Globular clusters are expected to emit gamma rays because of the large populations of millisecond pulsars that they contain. The spectral shape of 47 Tucanae is consistent with gamma-ray emission from a population of millisecond pulsars. The observed gamma-ray luminosity implies an upper limit of 60 millisecond pulsars present in 47 Tucanae.

TI A Population of Gamma-Ray Millisecond Pulsars Seen with the Fermi Large
Area Telescope
SO SCIENCE
LA English
DT Article
ID SPACE-TELESCOPE; RADIO PULSARS; EMISSION; DISCOVERY
AB Pulsars are born with subsecond spin periods and slow by electromagnetic braking for several tens of millions of years, when detectable radiation ceases. A second life can occur for neutron stars in binary systems. They can acquire mass and angular momentum from their companions, to be spun up to millisecond periods and begin radiating again. We searched Fermi Large Area Telescope data for pulsations from all known millisecond pulsars (MSPs) outside of globular clusters, using rotation parameters from radio telescopes. Strong gamma-ray pulsations were detected for eight MSPs. The gamma-ray pulse profiles and spectral properties resemble those of young gamma-ray pulsars. The basic emission mechanism seems to be the same for MSPs and young pulsars, with the emission originating in regions far from the neutron star surface.

AB Clear sky and other cloud-related contextual biases are critical yet unsolved mysteries for aerosol related climatological studies using satellite observations. For the first time, we simulated contextual biases over ocean using 2-years of Navy Aerosol Analysis and Prediction System (NAAPS) products that include the Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol optical depth (AOD) assimilation. We compared model-derived AOD in regions with and without observations, and found that sampling results in negligible seasonal globally averaged AOD bias (<5%). Biases are more pronounced in regions with frequent overcast skies and high aerosol loadings, such as Southeast Asia, and mid-latitude South America. This suggests that contextual biases may develop from transport covariance and other observing biases. Lastly, we found that over remote oceans, under cloud decks, a slight increase aerosol optical depth values could exist, comparing with cloud free regions. But this is still small relative to cloud artifacts in the retrieval. Citation: Zhang, J., and J. S.

AB Rapid and effective detection and identification of emerging microbiological threats and potential biowarfare agents is very challenging when using traditional culture-based methods. Contemporary molecular techniques, relying upon reverse transcription and/or polymerase chain reaction (RT-PCR/PCR) provide a rapid and effective alternative, however, such assays are generally designed and optimized to detect only a limited number of targets, and seldom are capable of differentiation among variants of detected targets. To meet these challenges, we have designed a broad-range resequencing pathogen microarray (RPM) for detection of tropical and emerging infectious agents (TEI) including biothreat agents: RPM-TEI v 1.0 (RPM-TEI). The scope of the RPM-TEI assay enables detection and differential identification of 84 types of pathogens and 13 toxin genes, including most of the class A, B and C select agents as defined by the Centers for Disease Control and Prevention (CDC, Atlanta, GA). Due to the high risks associated with handling these particular target pathogens, the sensitivity validation of the RPM-TEI has been performed using an innovative approach, in which synthetic DNA fragments are used as templates for testing the assay's limit of detection (LOD). Assay specificity and sensitivity was subsequently confirmed by testing with full-length genomic nucleic acids of selected agents. The LOD for a majority of the agents detected by RPM-TEI was determined to be at least 10 4 copies per test. Our results also show that the RPM-TEI assay not only detects and identifies agents, but is also able to differentiate near neighbors of the same agent types, such as closely related strains of filoviruses of the Ebola Zaire group, or the Machupo and Lassa arenaviruses. Furthermore, each RPM-TEI assay results in specimen-specific agent gene sequence information that can be used to assess pathogenicity, mutations, and virulence markers, results that are not generally available from multiplexed RT-PCR/PCR-based detection assays.

AB We show that the dominant energy loss mechanism in plate modes of a 1.5 mu m thick silicon micromechanical resonator is thermoelastic damping. In situ ultra-high vacuum annealing lowers the dissipation of two neighboring resonance modes (460 and 510 kHz) at 120 K to Q(-1)< 5x10(-7). From 120 to 400 K, the Q(-1) of these modes increase at different rates, in quantitative agreement with a modification (that accounts for mode shape) of Zener's theory of thermoelastic damping.

AB The availability of high-quality synoptic observations of the extreme-ultraviolet (EUV) and visible corona during the SOHO mission has advanced our understanding of the low corona manifestations of coronal mass ejections (CMEs). The EUV imager/white light coronagraph connection has been proven so powerful, it is routinely assumed that if no EUV signatures are present when a CME is observed by a coronagraph, then the event must originate behind the visible limb. This assumption carries strong implications for space weather forecasting but has not been put to the test. This paper presents the first detailed analysis of a frontside, large-scale CME that has no obvious counterparts in the low corona as observed in EUV and H alpha wavelengths. The event was observed by the SECCHI instruments onboard the STEREO mission. The COR2A coronagraph observed a slow flux-rope-type CME, while an extremely faint partial halo was observed in COR2B. The event evolved very slowly and is typical of the streamer-blowout CME class. EUVI A 171 angstrom images show a concave feature above the east limb, relatively stable for about two days before the eruption, when it rises into the coronagraphic fields and develops into the core of the CME. None of the typical low corona signatures of a CME (flaring, EUV dimming, filament eruption, waves) were observed in the EUVI B images, which we attribute to the unusually large height from which the flux rope lifted off. This interpretation is supported by the CME mass measurements and estimates of the expected EUV dimming intensity. Only thanks to the availability of the two viewpoints we were able to identify the likely source region. The event originated along a neutral line over the quiet-Sun. No active regions were present anywhere on the visible (from STEREO B) face of the disk. Leaving no trace behind on the solar disk, this observation shows unambiguously that a CME eruption does not need to have clear on-disk signatures. Also it sheds light on the question of "mystery" geomagnetic storms, storms without clear solar origin (formerly called problem storms). We discuss the implications for space weather monitoring. Preliminary inspection of STEREO data indicates that events like this are not uncommon, particularly during the ongoing period of deep solar minimum.

AB The solar energetic (E > 1 MeV nucleon(-1)) particles (SEPs) observed in gradual events at 1 AU are assumed to be accelerated by coronal/interplanetary shocks from ambient thermal or suprathermal seed particles. If so, then the elemental abundances of SEPs produced in different solar wind (SW) stream types (transient, fast, and slow) might be systematically distinguished from each other. We look for these differences in SEP energy spectra and in elemental abundance ratios (including Mg/Ne and Fe/C, which compare low/high first ionization potential elements), in a large number of SEP time intervals over the past solar cycle. The SW regions are characterized by the three-component stream classification of Richardson et al. Our survey shows no significant compositional or energy spectral differences in the 5-10 MeV nucleon(-1) range for SEP events of different SW stream types. This result extends the earlier finding that SEP events are observed frequently in fast SW streams, although their higher Alfven and SW flow speeds should constrain SEP production by coronal mass ejection-driven shocks in those regions. We discuss the implications of our results for shock seed populations and cross-field propagation.

TI Sterile Protection against Plasmodium knowlesi in Rhesus Monkeys from a
Malaria Vaccine: Comparison of Heterologous Prime Boost Strategies
SO PLOS ONE
LA English
DT Article
AB Using newer vaccine platforms which have been effective against malaria in rodent models, we tested five immunization regimens against Plasmodium knowlesi in rhesus monkeys. All vaccines included the same four P. knowlesi antigens: the pre-erythrocytic antigens CSP, SSP2, and erythrocytic antigens AMA1, MSP1. We used four vaccine platforms for prime or boost vaccinations: plasmids (DNA), alphavirus replicons (VRP), attenuated adenovirus serotype 5 (Ad), or attenuated poxvirus (Pox). These four platforms combined to produce five different prime/boost vaccine regimens: Pox alone, VRP/Pox, VRP/Ad, Ad/Pox, and DNA/Pox. Five rhesus monkeys were immunized with each regimen, and five Control monkeys received a mock vaccination. The time to complete vaccinations was 420 days. All monkeys were challenged twice with 100 P. knowlesi sporozoites given IV. The first challenge was given 12 days after the last vaccination, and the monkeys receiving the DNA/Pox vaccine were the best protected, with 3/5 monkeys sterilely protected and 1/5 monkeys that self-cured its parasitemia. There was no protection in monkeys that received Pox malaria vaccine alone without previous priming. The second sporozoite challenge was given 4 months after the first. All 4 monkeys that were protected in the first challenge developed malaria in the second challenge. DNA, VRP and Ad5 vaccines all primed monkeys for strong immune responses after the Pox boost. We discuss the high level but short duration of protection in this experiment and the possible benefits of the long interval between prime and boost.

TI Comparison of COSMIC occultation-based electron density profiles and TIP
observations with Arecibo incoherent scatter radar data
SO RADIO SCIENCE
LA English
DT Article
AB In June 2006 an early opportunity arose to compare occultation-based electron density profiles with incoherent scatter radar data. The former were made available by the constellation of satellites called COSMIC. We find that the value of the peak plasma density in the F region is reasonably well characterized but that the altitude of the peak is overestimated above about 300 km and underestimated below that height. A simple Abel transform is not suitable for determining the E region profiles, even in daytime. We also compared the emission strength recorded by the Tiny Ionospheric Photometer (TIP) on board COSMIC to the Arecibo measurement of the TEC as part of an ongoing effort to calibrate the former. The TIP and Arecibo data both show the development of an ionospheric storm of the type referred to as high-intensity, long-duration continuous AE activity. It is surprising that such a modest magnetic storm (Dst similar to -2.5 nT) resulted in wthe anomaly moving to nearly 30 degrees magnetic latitude.

AB A global Earth Magnetic Anomaly Grid (EMAG2) has been compiled from satellite, ship, and airborne magnetic measurements. EMAG2 is a significant update of our previous candidate grid for the World Digital Magnetic Anomaly Map. The resolution has been improved from 3 arc min to 2 arc min, and the altitude has been reduced from 5 km to 4 km above the geoid. Additional grid and track line data have been included, both over land and the oceans. Wherever available, the original shipborne and airborne data were used instead of precompiled oceanic magnetic grids. Interpolation between sparse track lines in the oceans was improved by directional gridding and extrapolation, based on an oceanic crustal age model. The longest wavelengths (>330 km) were replaced with the latest CHAMP satellite magnetic field model MF6. EMAG2 is available at http://geomag.org/models/EMAG2 and for permanent archive at http://earthref.org/ cgi-bin/er.cgi?s=erda.cgi?n=970.

AB The Department of Defense is the largest consumer of middle distillate fuels. It has been recommended that alternative fuel sources be considered as replacements or blending stocks for middle distillate ground transportation and marine fuels. Therefore, the search for suitable replacements or blending stocks is earnestly continuing. Renewable agricultural crops such as soybeans and others are now in the forefront. Nonrenewable synthetic fuels such as those produced by Fischer-Tropsch, FT, synthesis from coal and natural gas have been suggested. It is probable that several of these substitutes would be simultaneously blended into a middle distillate petroleum based diesel fuel. Care must be employed when blending fuels so that fuel specifications and storage stability are not decreased. This paper compares the storage stability of a three-part mixture consisting of Fischer-Tropsch diesel, a petroleum diesel, and a 5% and 10% soy biodiesel under ambient conditions.

ID LOW-LATITUDE IONOSPHERE; TOPSIDE IONOSPHERE; REGION; MODEL
AB The first simulation study of ion (O(+) and H(+)) and electron temperature evolution during equatorial spread F (ESF) is presented. The simulation results are based on the Naval Research Laboratory (NRL) SAMI3/ESF three-dimensional code. It is found that the ions and electrons undergo both cooling and heating during bubble evolution. The main cause of cooling is adiabatic, associated with the increase of the flux tube volume as the plasma bubble rises. Ion heating is primarily caused by the compression of ions as they stream down the converging magnetic field. The electrons are heated by collisional coupling with the ions. Additionally, it is found that the electrons are heated at high altitudes (greater than or similar to 1200 km) because of thermal conduction, and that hydrogen ions can be heated at relatively low altitudes (similar or equal to 300 km) because of ion-neutral frictional heating. We compare the simulation results with observations from the ROCSAT and Hinotori satellites. Citation: Huba, J. D., G. Joyce, J. Krall, and J.

AB A novel method is presented for the beam shaping of far field intensity distributions of coherently combined fiber arrays. The fibers are arranged uniformly on the perimeter of a circle, and the linearly polarized beams of equal shape are superimposed such that the far field pattern represents an effective radially polarized vector beam, or discrete cylindrical vector (DCV) beam. The DCV beam is produced by three or more beams that each individually have a varying polarization vector. The beams are appropriately distributed in the near field such that the far field intensity distribution has a central null. This result is in contrast to the situation of parallel linearly polarized beams, where the intensity peaks on axis. (C) 2009 Optical Society of America

AB The potential of image-based computational modeling for determining the microstructural features that cause initial plastic flow (yield) in metals is investigated using a beta-Ti alloy as the focus material. A high-fidelity three-dimensional (3-D) morphological and crystallographic description of approximately 100 metallic grains is embedded into crystal plasticity finite-element models to analyze the microscale heterogeneity of material response under a set of loading conditions applied at the mesoscale. Preliminary results show that regardless of the globally applied loading condition most of the plastic flow initially occurs generally within only one of the two grains at a grain boundary. Additionally, it was determined that initial local plastic slip is suppressed in a compliant grain neighbored by relatively stiff grains under multiple loading conditions. Overall, the analysis demonstrates that the image-based modeling framework should be used in conjunction with sophisticated data-mining tools for identification of microstructure-property correlations in polycrystalline metals provided a statistically relevant number of grains are accommodated in the models. However, smaller volumes may still be used to investigate the local effect of microstructural features on mechanical behavior. (C) 2009 Acta Materialia Inc. Published by Elsevier Ltd.

AB Wireless sensor nodes are envisioned to be deployed in the urban and indoor environments. With the advancement of technologies, Such as nano-wires and molecular circuits, sensor nodes will become small, cheap and power efficient. At present, many researchers ire implementing and developing protocols with MICAz motes. Thus, it is important to understand the propagation characteristics of the MICAz motes. Antenna patterns and interferences are measured. In addition, software models of the mote and environment are created with the CST Microwave Studio and Rhino; afterwards, they are feed into Urbana and are Simulated. The simulated and measured results are compared, thus, validating the correctness of models, which are later used to simulate the urban and indoor environments in Urbana. Published by Elsevier B.V.

ID SHOCK ASSOCIATED NOISE; SCREECH TONES; ALGORITHM; SOUND; FCT
AB Large-eddy simulations of imperfectly expanded jet flows from a convergent-divergent nozzle with a sharp contraction at the nozzle throat have been carried out. The flowfield and near-field acoustics for various total pressure ratios from overexpanded to underexpanded jet flow conditions have been investigated. The location and spacing of the shock cells are in good agreement with experimental data and previous theoretical results. The velocity profiles are also in good agreement with data from experimental measurements. A Mach disk is observed immediately downstream of the nozzle exit for overexpanded jet conditions with nozzle pressure ratios much lower than the fully expanded value. It is found that this type of nozzle with a sharp turning throat does not have a shock-free condition for supersonic jet flows. The near-field intensities of pressure fluctuations show wavy structures for cases in which screech tones are observed. The large-eddy simulations predictions of the near-field noise intensities show good agreement with those obtained from experimental measurements. This good agreement shows that large-eddy simulations and measurements can play complementary roles in the investigation of the noise generation from supersonic jet flows.

AB Background: In sum, 1-, 2-, and 4-stranded allografts are used for soft tissue anterior cruciate ligament reconstruction; however, the fixation properties of fixation devices are not well assessed.
Hypothesis: There are no differences in the biomechanical characteristics of 1 (Achilles)-, 2 (posterior tibialis)-, and 4 (semitendinosus)-stranded allograft tibial fixation.
Study Design: Controlled laboratory study.
Methods: Sixty-three fresh-frozen porcine tibiae were used to evaluate the fixation of 1-, 2-, and 4-stranded human tendon allografts (Achilles, posterior tibialis, and semitendinosus) with 3 fixation devices (Delta, Intrafix, and Calaxo screws). With use of a materials testing system, each graft was subjected to 500 cycles of loading (50-250 N, 0.75 mm/sec) to determine displacement and cyclic stiffness, followed by a monotonic failure test (20 mm/min) to determine maximum load and pullout stiffness.
Results: For each graft type, there were no significant biomechanical differences between fixation devices. However, the 1-stranded graft (Achilles) construct demonstrated significantly higher mean displacement (3.17 +/- 1.62 mm), lower cyclical stiffness (156 +/- 25 N/mm), lower load to failure (479 +/- 87 N), and lower pullout stiffness (140 +/- 28 N/mm). In comparison with the 2-stranded graft (posterior tibialis), the 4-stranded graft (semitendinosus) exhibited lower displacement (0.86 +/- 0.44 to 1.12 +/- 0.51 mm) and higher ultimate failure load (832 +/- 255 to 656 +/- 168 N). Numerous differences in fixation properties were noted when comparing a device to each of the 3 grafts.
Conclusion: The 1-stranded allograft demonstrated inferior biomechanical tibial fixation properties when compared with 2 (posterior tibialis)-and 4 (semitendinosus)-stranded allograft constructs for all fixation devices tested.
Clinical Relevance: This study demonstrated that not all tibial fixation devices are designed to adequately accommodate different types of anterior cruciate ligament allografts. Biomechanical evidence suggests that caution is warranted when using an Achilles allograft fixated solely with an interference device.

AB Cutaneous leishmaniasis (CL) is prevalent in the Egyptian Sinai Peninsula and Previous research has consistently documented the etiologic a Leishmania gent to he Leishmania major. We report the first isolation of Leishmania tropica from human cases of CL in a Northern Sinai community bordering Palestine. Parasite real-time polymerase chain reaction (PCR), gene sequencing. and restriction fragment length polymorphism (RFLP) analyses indicate CL cases in this community were Caused by either L. major or L. tropica (three cases each). Two wild-caught rodents (Gerbillus pyramidum floweri) were infected with L. tropica. Phlebotomus papatasi sand flies were found harboring L. major, however only non-infected individuals of Phlebotomus sergenti, a vector for L. tropica, Were caught. Patients with L. tropica had not traveled from the region in over a year. suggesting these cases are autochthonous. This scenario is consistent with an incursion of L. tropica from bordering countries and raises concerns about expansion of this parasite further into Egypt.

AB Introduction: In several fields of surgery, the treatment of complicated tissue defects is an unsolved clinical problem. In particular, the use of tissue scaffolds has been limited by poor revascularization and integration. In this study, we developed a polymer, poly-N-acetyl-glucosamine (sNAG), with bioactive properties that may be useful to overcome these limitations.
Objective: To develop a scaffold-like membrane with bioactive properties and test the biologic effects in vitro and in vivo in diabetic wound healing.
Methods: In vitro, cells-nanofibers interactions were tested by cell metabolism and migration assays. In vivo, full thickness wounds in diabetic mice (n = 15 per group) were treated either with sNAG scaffolds, with a cellulosic control material, or were left untreated. Wound healing kinetics, including wound reepithelialization and wound contraction as well as microscopic metrics such as tissue growth, cell proliferation (Ki67), angiogenesis (PECAM-1), cell migration (MAP-Kinase), and keratinocyte migration (p 63) were monitored over a period of 28 days. Messenger RNA levels related to migration (uPAR), angiogenesis (VEGF), inflammatory response (IL-1 beta), and extracellular matrix remodeling (MMP3 and 9) were measured in wound tissues.
Results: sNAG fibers stimulated cell metabolism and the in vitro migratory activity of endothelial cells and fibroblasts. sNAG membranes profoundly accelerated wound closure mainly by reepithelialization and increased keratinocyte migration (7.5-fold), granulation tissue formation (2.8-fold), cell proliferation (4-fold), and vascularization (2.7-fold) compared with control wounds. Expression of markers of angiogenesis (VEGF), cell migration (uPAR) and ECM remodeling (MMP3, MMP9) were up-regulated in sNAG treated wounds compared with controls.
Conclusions: The key mechanism of the bioactive membranes is the cell-nanofiber stimulatory interaction. Engineering of bioactive materials may represent the clinical solution for a number of complex tissue defects.

A theoretical model is also presented, incorporating the effect of the heat perturbation shape, which accurately predicts the measurement behavior. It is shown that the measurement accuracy and spatial resolution are dramatically improved by removing the effect of the heat perturbation shape on the reconstructed profile using a deconvolution technique. The improvement in accuracy is illustrated by the excellent agreement between a weak grating reconstructed with OSDR and the same grating reconstructed with optical frequency domain reflectometry and a layer-peeling method. Reconstruction of a strong grating with an integrated coupling coefficient, (q) over barL = 8.14, demonstrates the utility of this technique. (C) 2009 Optical Society of America

ID SENSITIZED SOLAR-CELLS; CONTACT RESISTANCE; PENTACENE
AB Organic thin-film transistors (OTFTs) with top- and bottom-contact configurations were fabricated using silver nano-inks printed by laser forward transfer for the gate and source/drain electrodes with pentacene and poly-4-vinylphenol as the organic semiconductor and dielectric layers, respectively. The volume of the laser-printed Ag pixels was typically in the subpicoliter (0.2-0.4 pl) range. The top-contact OTFTs resulted in lower contact resistance compared to those obtained from the bottom-contact OTFTs, and showed improved overall device performance. The top-contact OTFTs exhibited field-effect mobilities of similar to 0.16 cm(2) V(-1) s(-1) and on/off current ratios of similar to 10(5).

ID 2 CANDIDATE MATERIALS
AB We have successfully developed a Seebeck coefficient Standard Reference Material (SRM((TM))), Bi(2)Te(3), that is crucial for inter-laboratory data comparison and for instrument calibration. Certification measurements were performed using two different techniques on 10 samples randomly selected from a batch of 390 bars. The certified Seebeck coefficient values are provided from 10 to 390 K. The availability of this SRM will validate the measurement accuracy, leading to a better understanding of the structure/property relationships, and the underlying physics of new and improved thermoelectric materials. An overview of the measurement techniques and data analysis is given.

AB Anterior shoulder instability is a common orthopaedic problem, and the Surgical treatment, both open and arthroscopic, has been shown to effectively restore stability and prevent recurrence. However, despite success with these Surgical techniques, there are several clinically relevant complications associated with both open and arthroscopic techniques for anterior shoulder stabilization. These complications can be subdivided into preoperative, intraoperative, and postoperative and include entities such as nerve injury, chondrolysis, incomplete treatment of associated lesions, and subscapularis dysfunction. When they occur, complications may significantly impact patient outcomes and function. Therefore, surgeon awareness and identification of the factors associated with these complications may help prevent occurrence. Although failure of instability repair can be classified as a complication of surgery, it requires an entirely separate discussion and is therefore not addressed in this article. Because most of the previously published Studies on anterior shoulder instability have emphasized surgical technique and clinical outcomes, the purpose of this article is to define the complications associated with anterior instability repair and provide recommendations on techniques that may be used to help avoid them.

SO ASIA-PACIFIC JOURNAL OF ATMOSPHERIC SCIENCES

DE Tropical cyclone formation; numerical weather prediction model
performance; Tropical Cyclone Structure 2008; THORPEX Pacific Asian
Regional Campaign
ID WESTERN NORTH PACIFIC
AB One of the objectives of the combined Tropical Cyclone Structure (TCS08) and THORPEX Pacific Asian Regional Campaign (T-PARC) field experiment during August and September 2008 was to improve understanding and prediction of western North Pacific tropical cyclone formation. One approach during TCS08 was to subjectively monitor the performance of the four global models as to whether any of the more than 50 deep convective regions labeled as TCSxxx were predicted to become a tropical depression. When a 850-mb vorticity maximum associated with the convective region could be followed in all four models, a consensus of the track forecasts to 72 h provided surprisingly good guidance for the pre-tropical cyclone seedlings and tropical depressions. An experienced analyst was able to recognize signatures in each of the models that indicate tropical cyclone formation was likely or unlikely. When all four global model forecasts were in agreement that formation was likely, high confidence could be given to the predicted scenario. This four-model consensus approach to predict tropical depression formation was most effective for the four pre-tropical cyclone seedlings that would later become typhoons, and did predict with less advance warning two seedlings that later became tropical storms. However, the global models did not consistently predict the four pre-tropical cyclone seedlings that only attained tropical depression status. The four-model consensus had a relatively small number of false alarms. Even though a three-model consensus had somewhat more false alarms, in most of the low latitude cases the lack of time continuity and a systematic decrease in consensus time to formation will make these cases relatively easy to recognize as false alarms.

TI PROBING FINE-SCALE IONOSPHERIC STRUCTURE WITH THE VERY LARGE ARRAY RADIO

DE atmospheric effects; techniques: interferometric
ID FREQUENCY SKY SURVEY; 74 MHZ; SYSTEM
AB High-resolution (similar to 1 arcmin) astronomical imaging at low frequency (<= 150 MHz) has only recently become practical with the development of new calibration algorithms for removing ionospheric distortions. In addition to opening a new window in observational astronomy, the process of calibrating the ionospheric distortions also probes ionospheric structure in an unprecedented way. Here we explore one aspect of this new type of ionospheric measurement: the differential refraction of celestial source pairs as a function of their angular separation. This measurement probes variations in the spatial gradient of the line-of-sight total electron content (TEC) to similar to 10(-3) TECU km(-1) (1 TECU = 10(12) cm(-2)) accuracy over spatial scales of under 10 km to over 100 km. We use data from the VLA Low-frequency Sky Survey (VLSS), a nearly complete 74 MHz survey of the entire sky visible to the VLA telescope in Socorro, New Mexico. These data comprise over 500 hr of observations, all calibrated in a standard way. While ionospheric spatial structure varies greatly from one observation to the next, when analyzed over hundreds of hours, statistical patterns become apparent. We present a detailed characterization of how the median differential refraction depends on source pair separation, elevation, and time of day. We find that elevation effects are large, but geometrically predictable and can be "removed" analytically using a "thin-shell" model of the ionosphere. We find significantly greater ionospheric spatial variations during the day than at night. These diurnal variations appear to affect the larger angular scales to a greater degree indicating that they come from disturbances on relatively larger spatial scales (hundreds of kilometers, rather than tens of kilometers).

AB A new catalog of visual double systems containing eclipsing binaries as one component is presented. The main purpose of this catalog is to compile a complete list of all known multiples of this variety, both for current analysis and to highlight those in need of additional observations. All available photometric and astrometric data were analyzed, resulting in new orbits for eight systems and new times of minimum light for a number of the eclipsing binaries. Some of the systems in the catalog have acceptable solutions for their visual orbits, although in most cases their orbital periods are too long for simultaneous analysis. Also included, however, are a number of systems which currently lack an orbital solution but which may be suitable for simultaneous analysis in the future.

AB Results of a phenomenological model to estimate the gamma-ray burst (GRB) detection rate by the Fermi Gamma-Ray Space Telescope are reported. This estimate is based on the Burst and Transient Source Experiment (BATSE) 4B GRB fluence distribution, the mean ratio of fluences measured at 100 MeV-5 GeV with Energetic Gamma-Ray Experiment Telescope (EGRET) and at 20 keV-2 MeV with BATSE, and the mean EGRET GRB spectrum for the five EGRET spark-chamber GRBs. For a 10% fluence ratio and a number spectral index alpha(1) = -2 at 100 MeV-5 GeV energies, we estimate a rate of approximate to 20 and 4 GRBs yr(-1) in the Fermi Large Area Telescope field of view (FOV) with at least five photons with energy E > 100 MeV and E > 1 GeV, respectively. We also estimate approximate to 1.5 GRBs yr(-1) in the Fermi FOV where at least one photon with energy E > 10 GeV is detected. For these parameters, we estimate approximate to 1-2 GRBs yr(-1) detected with the Fermi telescope with more than 100 gamma-rays with E greater than or similar to 100 MeV. Comparison predictions for alpha(1) = -2.2, different fluence ratios, and the AGILE gamma-ray satellite are made. Searches for different classes of GRBs using a diagram plotting 100 MeV-10 GeV fluence versus 20 keV-20 MeV fluence is considered as a way to search for separate classes of GRBs and, specifically, spectral differences between the short-hard and long-duration GRB classes, and for hard components in GRBs.

AB We report the detection of pulsed gamma-rays from the young, spin-powered radio pulsar PSR J2021+3651 using data acquired with the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope (formerly GLAST). The light curve consists of two narrow peaks of similar amplitude separated by 0.468 +/- 0.002 in phase. The first peak lags the maximum of the 2 GHz radio pulse by 0.162 +/- 0.004 +/- 0.01 in phase. The integral gamma-ray photon flux above 100 MeV is (56 +/- 3 +/- 11) x 10(-8) cm(-2) s(-1). The photon spectrum is well described by an exponentially cut-off power law of the form dF/dE = kE(-Gamma)e((-E/Ec)), where the energy E is expressed in GeV. The photon index is Gamma = 1.5 +/- 0.1 +/- 0.1 and the exponential cut-off is E-c = 2.4 +/- 0.3 +/- 0.5 GeV. The first uncertainty is statistical and the second is systematic. The integral photon flux of the bridge is approximately 10% of the pulsed emission, and the upper limit on off-pulse gamma-ray emission from a putative pulsar wind nebula is < 10% of the pulsed emission at the 95% confidence level. Radio polarization measurements yield a rotation measure of RM = 524 +/- 4 rad m(-2) but a poorly constrained magnetic geometry. Re-analysis of Chandra X-ray Observatory data enhanced the significance of the weak X-ray pulsations, and the first peak is roughly phase aligned with the first gamma-ray peak. We discuss the emission region and beaming geometry based on the shape and spectrum of the gamma-ray light curve combined with radio and X-ray measurements, and the implications for the pulsar distance. Gamma-ray emission from the polar cap region seems unlikely for this pulsar.

AB We present the results of multi-frequency radio observing campaigns designed to elucidate the nature of radio emission from very low mass stars. We detect radio emission in an additional two epochs of the ultracool dwarf binary LP 349-25, finding that the observed emission is broad band and steady on timescales between 10 s and 10.7 hr, as well as on timescales of 0.6 and 1.6 years. This system is unusual for ultracool dwarfs with detectable radio emission, in exhibiting a lack of any large-scale variability, particularly the bursting ( periodic or aperiodic) behavior exhibited by the other objects with detectable levels of radio emission. We explore the constraints that the lack of variability on long-and short-timescales, and flat spectral index, imply about the radio-emitting structures and mechanism. The temporal constraints argue for a high latitude emitting region with a large inclination so that it is always in view, and survives for at least 0.6 years. Temporal constraints also limit the plasma conditions, implying that the electron density be n(e) < 4 x 10(5) cm(-3) and B < 130 G in order not to see time variations due to collisional or radiative losses from high-energy particles. The observations and constraints provided by them are most compatible with a nonthermal radio emission mechanism, likely gyrosynchrotron emission from a spatially homogeneous or inhomogeneous source. This indicates that, similar to behaviors noted for chromospheric, transition region, and coronal plasmas in ultracool dwarfs, the magnetic activity patterns observed in active higher mass stars can survive to the substellar boundary. We also present new epochs of multi-frequency radio observations for the ultracool dwarfs 2MASS 05233822-140322 and 2MASS14563831-2809473(= LHS 3003); each has been detected in at least one previous epoch but are not detected in the epochs reported here. The results here suggest that magnetic configurations in ultracool dwarfs can be long-lasting, and support the need for further radiomonitoring using a simultaneous, multi-frequency observing approach.

AB We perform the analysis of the iron K a lines detected in three sources representing three types of accreting compact sources: cataclysmic variable (CV) GK Per, neutron star (NS) Serpens X-1, and black hole (BH) GX 339-4. We find, using data from Epic-PN Camera onboard XMM-Newton observatory, that the iron K(alpha) emission line in GK Per has a noticeable red-skewed profile. We compare the GK Per asymmetric line with the red-skewed lines observed by XMM-Newton in Serpens X-1 and GX 339-4. The observation of the K(alpha) emission with red-skewed features in CV GK Per cannot be related to the redshift effects of General Relativity (GR). Therefore, if the mechanism of the K(alpha)-line formation is the same in CVs, NSs, and BHs then it is evident that the GR effects would be ruled out as a cause of red skewness of K(alpha) line. The line reprocessing in an outflowing wind has been recently suggested as an alternative model for a broad red-shifted iron line formation. In the framework of the outflow scenario the red-skewed iron line is formed in the strong extended wind due to its illumination by the radiation emanating from the innermost part of the accreting material. The outflow is a common phenomenon for CVs, NSs, and BHs. In this paper, we demonstrate that the asymmetric shapes of the lines detected from these CV, NS, and BH sources are well described with the wind (outflow) model. Furthermore we find by analyzing Rossi X-Ray Timing Explorer(RXTE) observations that when the strong red-skewed iron line is observed in GX 339-4 the high-frequency variability is strongly suppressed. While this fact is hard to reconcile with the relativistic models, it is consistent with the outflowing gas washing out high-frequency modulations of the radiation presumably originated in the innermost part of the source.

AB We analyze the evolution of a sigmoidal (S-shaped) active region toward eruption, which includes a coronal mass ejection (CME) but leaves part of the filament in place. The X-ray sigmoid is found to trace out three different magnetic topologies in succession: a highly sheared arcade of coronal loops in its long-lived phase, a bald-patch separatrix surface (BPSS) in the hours before the CME, and the first flare loops in its major transient intensity enhancement. The coronal evolution is driven by photospheric changes which involve the convergence and cancellation of flux elements under the sigmoid and filament. The data yield unambiguous evidence for the existence of a BPSS, and hence a flux rope, in the corona prior to the onset of the CME.

AB The nature of coronal mass ejection (CME)-associated low corona propagating disturbances, "extreme ultraviolet (EUV) waves," has been controversial since their discovery by EIT on SOHO. The low-cadence, single-viewpoint EUV images and the lack of simultaneous inner corona white-light observations have hindered the resolution of the debate on whether they are true waves or just projections of the expanding CME. The operation of the twin EUV imagers and inner corona coronagraphs aboard STEREO has improved the situation dramatically. During early 2009, the STEREO Ahead (STA) and Behind (STB) spacecrafts observed the Sun in quadrature having a approximate to 90 degrees angular separation. An EUV wave and CME erupted from active region 11012, on February 13, when the region was exactly at the limb for STA and hence at disk center for STB. The STEREO observations capture the development of a CME and its accompanying EUV wave not only with high cadence but also in quadrature. The resulting unprecedented data set allowed us to separate the CME structures from the EUV wave signatures and to determine without doubt the true nature of the wave. It is a fast-mode MHD wave after all.

AB We report, for the first time, the observation near the Earth of anomalous cosmic ray (ACR) particles throughout the interiors of interplanetary magnetic clouds (MCs) at the same intensity as outside the MCs. ACRs, accelerated in the outer heliosphere, have unique elemental abundances making their identity unambiguous as they probe these clouds from the outside. Thus, MCs, carried out from the Sun by coronal mass ejections (CMEs), are seen to contain no structures that are magnetically closed to the penetration of ions with energies above a few MeV amu(-1). As the MCs expand outward, they must fill their increasing volume with ACRs dynamically, to the same degree as neighboring "open" field lines. These observations cast doubt on conventional ideas about the closed field topologies of MCs and the cross-field transport of energetic particles. The ACR observations conflict with some reports of significant exclusion from MCs of solar energetic particles (SEPs) of comparable energy and rigidity. A process that allows cross-field transport of ACRs may also allow similar transport of SEPs late in events, causing the large spatial extent and uniformity of SEPs in "invariant spectral regions" extending far behind CME-driven shock waves.

We observed two different cavities with the Coronal Multichannel Polarimeter on 2005 April 21 and with Hinode/EIS on 2008 November 8. Inside both of these cavities, we find coherent velocity structures based on spectral Doppler shifts. These flows have speeds of 5-10 km s(-1), occur over length scales of tens of megameters, and persist for at least 1 hr. Flows in cavities are an example of the nonstatic nature of quiescent structures in the solar atmosphere.

AB Extrasystoles particularly premature atrial contractions noted during labour on the fetal heart rate monitoring strip are usually thought to be benign. In pregnancies complicated by fetal infection and/or the fetal inflammatory response syndrome, there are some data that extrasystoles noted during the intrapartum period may be related to neonatal sepsis and eventual poor neonatal outcome including death or neonatal encephalopathy. Additional observations are needed to substantiate this hypothesis.

AB HOYT RE, LAWSON BD, McGEE HA, STROMPOLIS ML, MCCLELLAN MA. Modafinil as a potential motion sickness countermeasure. Aviat Space Environ Med 2009; 80:709-15.
Introduction: Motion sickness adversely affects military air and sea operations. Medications help prevent motion sickness but are frequently associated with side effects. Better medications or combinations of medications are needed. Dextroamphetamine has documented anti-motion sickness effects but also has a potential for abuse. Modafinil is a relatively new central nervous system stimulant that has none of the drawbacks of dextroamphetamine, but has not been evaluated for the treatment of motion sickness. Methods: This double-blind, placebo-controlled study evaluated the anti-motion sickness efficacy of modafinil, alone or in combination with oral scopolamine. Moderate nausea was induced via a Coriolis cross-coupling stimulus. There were 60 participants who were assigned randomly to 1 of 3 conditions: 1) 2 placebo pills (DP); 2) modafinil plus placebo (MP); or 3) modafinil plus oral scopolamine (MS). The primary measure of drug efficacy was the number of head tilts tolerated upon reaching moderate nausea for 1 min without abatement. Results: The combination of modafinil and scopolamine (MS) allowed subjects to tolerate significantly more head tilts than placebo, but modafinil alone (MP) failed to differ significantly from placebo (DP). No significant cognitive performance decrements were observed among the three experimental conditions. Conclusion: Modafinil was not found to be more effective than placebo. Further testing is recommended to determine whether the potentially promising combination of modafinil and scopolamine provide,; better efficacy or fewer side effects than scopolamine administered alone.

AB The syntheses of new conformationally locked North- and South-bicyclo[3.1.0]hexene nucleosides is reported. The North analogues were synthesized by a convergent approach from the known (1S,2R,5R)-5-[(tert-butyldiphenylsilyloxy)methyl]bicyclo[3.1.0]hex-3-en-2-ol by Mitsunobu coupling with the nucleobases. The South analogues were synthesized from their bicyclo[3.1.0]hexane nucleoside precursors by the selective protection of the primary hydroxy group, conversion of the secondary alcohol into a good leaving group, and base-catalyzed elimination to generate the olefin. The transformation of a bicyclo[3.1.0]hexane nucleoside into a bicyclo[3.1.0]hexene nucleoside flattens the five-membered ring of the.. bicyclic system and rescues anti-HIV activity for North-D4T, North-D4A, and South D4C. The relationship between planarity and the anti/syn disposition of, the nucleobase that is favored by a particular pseudosugar platform are proposed as key parameters in controlling biological activity.

AB Campylobacter jejuni is 1 of the most common enteric bacterial pathogens worldwide. The mechanisms of pathogenesis remain obscure, in part because of limitations of small animal models. Young ferrets develop diarrhea when fed C. jejuni, but their pathology and the immune response after infection have not been examined in detail. In the present study, we examined the pathogenesis of C. jejuni CG8421 and associated immune responses in ferrets. After oral infection with C. jejuni CG8421,86.7% of the animals developed diarrhea and inflammatory responses that were similar to those seen in human infection. Pronounced histopathologic changes in the colonic mucosa of infected animals were observed during the acute phase (days 1 through 3) of infection. Electron micrographs of colonic epithelium revealed disruption of the villi and internalized bacteria that were not within membrane vacuoles. During the acute phase, C. jejuni was isolated from the livers of 7 of 9 (78%) animals, and bacteria were visualized immunohistochemically in the livers from 5 of the 7 animals (71%) from which C. jejuni was isolated. A vigorous systemic and mucosal immune response to Campylobacter antigens was elicited after infection of ferrets. The data presented contribute to the current knowledge of the pathogenicity of and immunologic response to C. jejuni CG8421 in ferrets and better understanding of this model.

AB We use a 9-km pan-Arctic ice-ocean model to better understand the circulation and exchanges in the Bering Sea, particularly near the shelf break. This region has, historically, been undersampled for physical, chemical, and biological properties. Very little is known about how water from the deep basin reaches the large, shallow Bering Sea shelf. To address this, we examine here the relationship between the Bering Slope Current and exchange across the shelf break and resulting mass and property fluxes onto the shelf. This understanding is critical to gain insight into the effects that the Bering Sea has on the Arctic Ocean, especially in regard to recent indications of a warming climate in this region. The Bering Sea shelf break region is characterized by the northwestward-flowing Bering Slope Current. Previously, it was thought that once this current neared the Siberian coast, a portion of it made a sharp turn northward and encircled the Gulf of Anadyr in an anticyclonic fashion. Our model results indicate a significantly different circulation scheme whereby water from the deep basin is periodically moved northward onto the shelf by mesoscale processes along the shelf break. Canyons along the shelf break appear to be more prone to eddy activity and, therefore, are associated with higher rates of on-shelf transport. The horizontal resolution configured in this model now allows for the representation of eddies with diameters greater than 36 km; however, we are unable to resolve the smaller eddies.

AB Colleges and universities face a principal-agent problem. There are information asymmetries over the actions chosen by administrators. Because non-profit constraints limit the financial stake of trustees there may be insufficient monitoring of administrators and, consequentially, shirking. It is conceivable that faculty will serve as "delegated monitors" given the proper incentives. Faculty monitoring will most likely benefit a university when: (1) monitoring costs are low and (2) administrators cannot impose significant punishment costs on faculty. The practices of organized faculty participation in governance and tenure naturally achieve such ends. Empirical evidence from a sample of colleges and universities in the United States supports the hypothesis that features of a faculty's employment have significant effects on a university's financial performance.

structure matter?
SO ECONOMICS OF EDUCATION REVIEW
LA English
DT Article

ID SOCIAL INTERACTIONS
AB Four alternative structures of peer groups are compared in an empirical analysis of teenage dropouts and recent drug use. In general, individual-specific covariates remain robust regardless of group structure specification in dropout models, but lose significance in models of drug-use. Estimates of correlated school effects depend on the specification of group structure. Contextual group effects have no influence on the probability that an individual uses drugs, but demonstrate some statistical significance, albeit ambiguous and strongly dependent on the specification of group structure. Endogenous peer effects do not influence the probability of dropping-out of school, but exhibit positive complementarities with respect to recent drug-use. Modeling the probabilities of leaving school and recent drug-use within a jointly distributed empirical framework indicates that unobserved attributes bridging the two types of behavior demonstrate positive correlation.

AB The hydrogenation of CO(2) using a traditional Fischer-Tropsch Co-Pt/Al(2)O(3) catalyst for the production of valuable hydrocarbon materials is investigated. The ability to direct product distribution was measured as a function of different feed gas ratios of H(2) and CO(2) (3:1, 2:1, and 1:1) as well as operating pressures (ranging from 450 to 150 psig). As the feed gas ratio was changed from 3:1 to 2:1 and 1:1, the production distribution shifted from methane toward higher chain hydrocarbons. This change in feed gas ratio is believed to lower the methanation ability of Co in favor of chain growth, with possibly two different active sites for methane and C(2)-C(4) products. Furthermore, with decreasing pressure, the methane conversion drops slightly in favor of C(2)-C(4) paraffins. Even though under certain reaction conditions product distribution can be shifted slightly away from the formation of methane, the catalyst studied behaves like a methanation catalyst in the hydrogenation of CO(2).

AB A powerful variable magnetic eddy current damping system has been constructed and utilized in an experimental study of vortex-induced vibrations (VIV). This damping system allows us to impose precise values of nearly ideal viscous damping over a wide range of damping values of interest. This new damping system offers improvements over previously utilized damping methods. Unlike most studies of VIV, where the damping cannot be independently controlled, we are able to impose our system damping independent of the other system parameters. Also, because the system only requires that a thin conductive plate be attached to the oscillating system, the overall mass of the system does not increase dramatically and still allows the investigation of very low mass systems. Finally, the system can operate in a steady-state fashion, supplying a constant damping value for an extended period of time, or in a transient fashion, where the damping value is intentionally varied over time. With this damping system, we have systematically explored both steady and transient damping effects on VIV behavior and provide a brief overview of some sample results.

AB The Fusion Test Facility (FTF) is a high repetition rate ignition facility that would bridge the gap between single shot facilities (such as NIF and LMJ) and a fully functioning laser fusion power plant. It would allow development of science and technologies so that follow-on power plants could have predictable performance. The FTF would need to have enough fusion power, about 100 MW to rigorously test materials and components for the power plants. Because inertial fusion provides a "point" source for neutrons, it can provide very high fluxes for test objects placed close to the target, while the reaction chamber walls remain at conservatively large distances. Simulations indicate that direct-drive designs can achieve 100 MW fusion power with laser energies well below I MJ with a 5 Hz driver. High-resolution 2-D simulations of high-velocity direct-drive implosions utilizing a Krypton-Fluoride (KrF) laser give gains of >60x at 500 kJ, and shock-ignited targets may allow higher gains at even lower driver energy. Utilizing designs that require relatively small driver energy is the most straightforward path to reducing cost and development time for a practical laser fusion energy power plant. A program to develop an FTF would build upon the science and technologies developed in the existing National Ignition Campaign and the High Average Power Laser (HAPL) program, as well as the magnetic fusion technology program.

AB Background: Oesophageal motility, as measured by manometry, is normal in the majority of patients with eosinophilic oesophagitis (EO). However, manometry measures only the circular muscle function of the oesophagus. The goal of the present study was to assess circular and longitudinal muscle function during peristalsis in patients with EO.
Methods: Ultrasound imaging and manometry were simultaneously acquired during swallow-induced peristalsis in patients with EO and controls to measure the longitudinal muscle and circular muscle contraction, respectively. A probe with an ultrasound transducer was positioned 2 cm and then 10 cm above the lower oesophageal sphincter and five, 5 ml water swallows were recorded before and after edrophonium.
Results: There is no difference in the incidence of swallow-induced peristalsis and manometric pressures (a marker of circular muscle contraction) between controls and patients with EO. However, changes in the muscle thickness (a marker of longitudinal muscle contraction) are markedly diminished in patients with EO, at both 2 and 10 cm above the lower oesophageal sphincter. The longitudinal muscle response to edrophonium is markedly blunted in patients with EO. Normal subjects demonstrate synchrony between the circular and longitudinal muscle contraction during peristalsis that is affected by edrophonium. On the other hand, patients with EO demonstrate mild asynchrony of circular and longitudinal muscle contraction during swallow-induced contractions that is not altered by edrophonium.
Conclusions: In patients with EO, there is selective dysfunction of the longitudinal muscle contraction during peristalsis. It is proposed that the longitudinal muscle dysfunction in EO may contribute to dysphagia.

AB Sufficient conditions are derived under which M-ary partial- and full-response continuous phase modulation (CPM) space-time (ST) codes will attain both full spatial diversity and optimal coding gain. General code construction rules are desirable due to the nonlinearity and inherent memory of the CPM signals which makes manual design or computer search difficult. Using a linear decomposition of CPM signals with tilted phase, we identify a rank criterion for M-ary partial- and full-response CPM that specifies the set of allowable modulation indices. We also propose a coding gain design criterion. Optimization of the coding gain for CPM ST codes is shown to depend on the CPM frequency/phase shaping pulse, modulation index, and codewords. The modulation indices and phase shaping functions that improve the coding gain are specified. Finally, optimization of coding gain for ST-CPM and orthogonal ST-CPM codewords is discussed.

Through a time-domain analysis of the sampled link architecture, we show that the link performance metrics reduce to those of a conventional analog optical link in the absence of photodiode nonlinearity. Experimental measurements of the link gain and third-order nonlinearity are presented, emphasizing the link performance as a function of received photocurrent. The work presented here demonstrates that the performance of sampled analog optical links rivals that of the conventional architecture, even in the presence of significant photodiode nonlinearity.

AB In this study, we use a freeze casting technique to construct ceramic-polymer composites in which the 2 phases are arranged in an electrically parallel configuration. By doing so, the composites exhibit dielectric constant (K) up to 2 orders or magnitude higher than that of composites with ceramic particles randomly dispersed in a polymer matrix. In this technique, an aqueous ceramic slurry was frozen unidirectionally to form ice platelets and ceramic aggregates that were aligned in the temperature gradient direction. Upon freeze-drying, the ice platelets sublimed and left the lamellar ceramic structure intact. The green ceramic body was fired to retain the microstructure, and then the space between ceramic lamellae was infiltrated with a polymer material. The finished composites exhibit the high dielectric constant (1000) of ferroelectric ceramics while maintaining the unique properties of polymer materials such as graceful failure., low dielectric loss, and high dielectric breakdown.

AB Objective: To determine current trends among American Society of Pediatric Otolaryngology members on the treatment of various stages of lymphatic malformation (LM) with an emphasis on tongue management.
Methods: We queried the members on practice demographics, number of LMs and LM-Mac treated, preferred treatment of different stages of LM and Lm-Mac, indications for LM-Mac tongue treatment, preferred method of surgical tongue reduction, and medical management of acutely enlarging LMs and LM-Mac.
Results: 39/329 (12%) American Society of Pediatric Otolaryngology members responded to the survey. Airway obstruction or obstructive sleep apnea (27/39, 69%) followed by recurrent tongue trauma with bleeding, pain or mucosal changes (11/39, 28%) were the most common indications for tongue management. 16/37 (43%) of respondents preferred staged tongue reduction followed by neck dissection (cervical approach to the LM), 8/37 (22%) preferred staged neck dissection followed by tongue reduction, and 13/37 (35%) preferred simultaneous treatment of the tongue and neck. The preferred methods of tongue reduction were superficial laser ablation (17/38, 45%) and surgical excision (14/39, 36%). The preferred methods of surgical tongue reduction were anterior wedge (18/38, 47%) and midline keyhole reduction (13/38. 34%). For rapidly enlarging lymphatic malformations involving the tongue, the majority of respondents indicated that they would admit and observe (34/38, 89%), give steroids (34/37, 92%) and administer antibiotics (35/38, 92%).
Conclusions: While providing insight into treatment patterns, this survey also helps to elucidate the need for multicenter trials for treatment of LM to develop a standard of care that can be recommended based on evidence based medicine rather. (C) 2009 Published by Elsevier Ireland Ltd.

AB A motion system collected 120-Hz data from 14 baseball adult hitters using normal and choke-up bat grips. Six swings were digitized for each hitter, and temporal and kinematic parameters were calculated. Compared with a normal grip, the choke-up grip resulted in 1) less time during stride phase and swing; 2) the upper torso more opened at lead foot contact; 3) the pelvis more closed and less bat linear velocity at bat-ball contact; 4) less range of motion of the upper torso and pelvis during swing; 5) greater elbow flexion at lead foot contact; and 6) greater peak fight elbow extension angular velocity. The decreased time during the stride phase when using a choke-up grip implies that hitters quicken their stride when they choke up. Less swing time duration and less upper torso and pelvis rotation range of motion using the choke-up grip supports the belief of many coaches and players that using a choke-up grip results in a "quicker" swing. However, the belief that using a choke-up grip leads to a faster moving bat was not supported by the results of this study.

ID GROUND REACTION FORCES; VELOCITIES; MECHANICS
AB We propose that learning proper hitting kinematics should be encouraged at a young age during youth baseball because this may help reinforce proper hitting kinematics as a player progresses to higher levels of baseball in their adult years. To enhance our understanding between youth and adult baseball hitting, kinematic and temporal analyses of baseball hitting were evaluated with a high-speed motion analysis system between 12 skilled youth and 12 skilled adult baseball players. There were only a small number of temporal differences between youth and adult hitters, with adult hitters taking significantly greater time than youth hitters during the stride phase and during the swing. Compared with youth hitters, adult hitters a) had significantly greater (p < .01) lead knee flexion when the hands started to move forward; b) flexed the lead knee over a greater range of motion during the transition phase (31 degrees versus 13 degrees); c) extended the lead knee over a greater range of motion during the bat acceleration phase (59 degrees versus 32 degrees); d) maintained a more open pelvis position at lead foot off ground; and e) maintained a more open upper torso position when the hands started to move forward and a more closed upper torso position at bat-ball contact. Moreover, adult hitters had greater peak upper torso angular velocity (857 degrees/s versus 717 degrees/s), peak left elbow extension angular velocity (752 degrees/s versus 598 degrees/s), peak left knee extension angular velocity (386 degrees/s versus 303 degrees/s), and bat linear velocity at bat-ball contact (30 m/s versus 25 m/s). The numerous differences in kinematic and temporal parameters between youth and adult hitters suggest that hitting mechanics are different between these two groups.

AB A numerical technique is developed for the spatial localization of 1/f noise sources in AlSb/InAs high-electron-mobility transistors. The technique is based on the microscopic modeling of 1/f noise using the method of Langevin random sources, in which the noise sources are introduced nonuniformly throughout the device. An efficient algorithm is proposed for the determination of the spatial distribution of these noise sources and local (mesh point) values of the Hooge parameter. The algorithm takes advantage of the linearity between the terminal noise current and the power of the noise sources and uses an optimization approach based on linear least-squares minimizations to find the distribution from the experimental noise characteristics. The density of noise sources in the InAs channel is found to be much larger near the top interface than at the bottom interface. The local values of the Hooge parameter vary from 10(-2) at the top to 3x10(-4) at the bottom of the channel.

AB High-sensitivity and low-noise electron tunneling spectroscopy was used to measure the phonon spectra via band-to-band tunneling in Si/SiGe resonant interband tunneling diodes (RITD), tracking the effects of the weighted average Ge percentage in the central tunneling spacer. With a composite RITD tunneling barrier consisting of 4 nm of intrinsic Si0.60Ge0.40 and n nm of intrinsic Si (n=4,6,8,10) all grown on Si substrates, the transverse acoustic (TA) phonon of Si0.60Ge0.40 was identified and the energy was measured to be 16 +/- 1 meV. This is higher than the similar to 14 meV energy of the TA phonon in Si0.60Ge0.40 reported from measurements of Esaki tunnel diodes fabricated from bulk single crystals. The increase is attributed to the compressive strain in the Si0.60Ge0.40 layer grown on Si substrates. The observation of the upshift of phonon energy with strain by electron tunneling spectroscopy demonstrates the capability of electron tunneling spectroscopy to characterize residual strain.

AB Photocathodes are a critical electron source component of accelerators and Free Electron Lasers, but their susceptibility to damage in the harsh environment of an rf photoinjector motivates methods to improve their Quantum Efficiency (QE), lifetime, and performance. In this review, we give an overview of photoemission theory and photocathode development, then describe the status of theoretical modeling of photoemission and the surface conditions of photocathodes that are central to their performance and operation. These models are then related to ongoing experimental efforts to vet the theory and develop a dispenser photocathode that relies on rejuvenating low work function coatings to maintain performance.

AB For a physical III-V or II-VI semiconductor, the optical constants, absorption coefficient, electron scattering cross section, and electron scattering rate are commonly derived from a quantum mechanical theory, using either a density matrix approach or second order perturbation theory. Generally, a number of material parameters are involved and numerical computation is required for results. This paper presents a theoretical model of a simplified "alpha semiconductor" that elucidates the relation between the optical constants and the underlying quantum mechanical processes, predicts the order of magnitude of optical quantities, and in some limits enables their calculation in terms of simpler analytical expressions. In particular the effective electron mass of the alpha semiconductor is related only to, and can be inferred from, the band gap energy. Comparisons are made between the alpha semiconductor model and various physical III-V and II-VI semiconductors for a variety of compounds. The alpha semiconductor model makes possible a theoretical treatment in which parameters can be approximated rather than treated as adjustable, thereby avoiding excessive numerical computation, and its application to the modeling of photoemission is briefly described.

We show that photo-thermal imaging allows for direct visual imaging of the bandgap region of CdTe and CdZnTe substrates. We also show that photo-thermal spectroscopy can provide epilayer thickness information independent of the dielectric function. The method is orthogonal to existing optical characterization techniques and could be combined with them for improved accuracy.

AB Abdominal pain is a common presenting complaint in the Emergency Department. It extends to all populations regardless of age, sex, or socioeconomic status. After gathering a history and examining the patient, most Emergency Physicians form a differential diagnosis and initiate an appropriate work-up. However, in the postpartum woman, additional causes must be considered and treated accordingly, knowing that there are consequences for both mother and child. We present a case of a postpartum woman presenting with right-sided abdominal pain, the cause of which, although atypical, has potential for significant morbidity and mortality if it goes undiscovered.

AB We have investigated the improvement in the phase noise of a 10 GHz optoelectronic oscillator using all-photonic gain as compared to using an electronic amplifier in the cavity. The optoelectronic oscillator achieves the necessary RF gain for oscillation by using the carrier-suppression technique of a low-biased Mach-Zehnder modulator (MZM) followed by optical amplification. The measured RF gain due to this all-photonic technique is as high as 15 dB and matches well with theoretical predictions. The phase noise of the generated 10 GHz signal is at least 10 dB lower than the signal from the same oscillator using an electronic amplifier. The improvement in the phase noise is due to the lower RF noise figure of the all-photonic gain process as compared to the electronic amplifier configuration.

AB States of two-level systems (systems with two eigen-states, such as optical propagation of polarized light or spin 1/2) are conventionally represented by 2 x 1 complex vectors or real 3 x 1 geometric vectors. A limitation of geometrical representations is an inability to represent overall phase, important in optical and quantum interference applications. We propose an extension of the usual geometrical representation for such systems, representing the overall phase as an additional, internal, spin of the geometric state vector. We generalize the earlier representations to include this phase, establish rules for its representation and calculation, and illustrate our model by analyzing an optical interferometer.

ID OCEAN DATA ASSIMILATION; SEA; WATER; GULF
AB High, small-scale SST variability (6 degrees C over 5-10 km) observed South of Martha's Vineyard during the low-wind component of the Coupled Boundary Layers Air-Sea Transfer (CBLAST-Low) oceanographic field program in August 2003 is investigated using the Navy Coastal Ocean Model (NCOM), with atmospheric forcing provided by the Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS (R)).(1) The ocean model includes tidal boundary forcing by the eight major tidal constituents, which is superimposed on the non-tidal lateral boundary conditions obtained from the 1/8 degrees global NCOM real-time hindcast. The simulation is conducted with a high-resolution, 200-m grid, with bathymetry from the NGDC 3-arc-second Coastal Relief Model. The COAMPS fields, tidal forcing and NCOM results are evaluated with the CBLAST-Low observations and previous results. Both the simulation and observation analyses reveal that SST variability south of Martha's Vineyard is significant on August 18 and 25 and is strongly related to the cooling events on August 17 to 18 and August 24 to 25. The northeast winds passing through Muskeget Channel generate sharp horizontal SST gradients on August 18 by accelerating the westward transport of cold water from the cold, tidally-mixed Nantucket Shoals and by wind-induced upwelling and surface-cooling-induced vertical mixing. The mechanism of SST change on August 25 is differentiated from the change on August 18 by the northwest winds being unfavorable to the westward transport of cold water. The SST cooling on August 25 is mainly caused by local vertical mixing induced by heat lost. (C) Published by Elsevier B.V.

AB Traumatic brain injury (TBI) is a leading cause of sustained impairment in military and civilian populations. However, mild (and some moderate) TBI can be difficult to diagnose due to lack of obvious external injuries and because the injuries are often not visible on conventional acute MRI or CT. Injured brain tissues in TBI patients generate pathological low-frequency neuronal magnetic signal (delta waves 1-4 Hz) that can be measured and localized by magnetoencephalography (MEG). We hypothesize that abnormal MEG delta waves originate from gray matter neurons that experience de-afferentation due to axonal injury to the underlying white matter fiber tracts, which is manifested on diffusion tensor imaging (DTI) as reduced fractional anisotropy.
The present study used a neuroimaging approach integrating findings of magnetoencephalography (MEG) and diffusion tensor imaging (DTI), evaluating their utility in diagnosing mild TBI in 10 subjects in whom conventional CT and MRI showed no visible lesions in 9.
The results show: (1) the integrated approach with MEG and DTI is more sensitive than conventional CT and MRI in detecting subtle neuronal injury in mild TBI; (2) MEG slow waves in mild TBI patients originate from cortical gray matter areas that experience de-afferentation due to axonal injuries in the white matter fibers with reduced fractional anisotropy; (3) findings from the integrated imaging approach are consistent with post-concussive symptoms; (4) in some cases, abnormal MEG delta waves were observed in subjects without obvious DTI abnormality, indicating that MEG may be more sensitive than DTI in diagnosing mild TBI.

AB In this paper, the combined effects of refraction and nonlinearity on the evolution of ocean surface wave statistics are considered and possible implications for the likelihood of extreme waves, also known as freak or rogue waves, are examined. A frequency-angular spectrum model is derived that accounts for cubic nonlinear dynamics and weak lateral homogeneity of the medium. Through Monte Carlo simulations, the evolution of wave statistics in freely developing waves, waves over an opposing shearing current, and waves refracted over an isolated topographical feature is modeled. The simulations show that freely developing, directionally spread wave fields generally maintain near-Gaussian statistics, which was also found in earlier model studies. However, the enhanced nonlinearity caused by the refractive focusing of narrowband wave fields can result locally in strongly non-Gaussian statistics and an associated increased likelihood of extreme wave events.

The resultant terminally functionalized dendritic azido and acetylenic groups undergo 1,3-dipolar cycloaddition using methyl (or ethyl) propiolate and benzyl azide, respectively, under catalytic or noncatalytic conditions below 40 C to yield 1,2,3-triazole dendrimeric polymers in 82-95% yield, under extremely mild conditions that could be applied for compounds sensitive to acid, base, or heat. The dendritic azido and activated acetylenic derivatives may act as novel scaffolds to tune the mechanical properties of different polymers. (C) 2009 Wiley Periodicals, Inc.

The ranges varied from 50 to 3200 km. In addition to predicted ocean acoustic arrivals and deep shadow zone arrivals (leaking below turning points), "deep seafloor arrivals," that are dominant on the seafloor geophone but are absent or very weak on the hydrophone array, are observed. These deep seafloor arrivals are an unexplained set of arrivals in ocean acoustics possibly associated with seafloor interface waves. (C) 2009 Acoustical Society of America. [DOI: 10.1121/1.3158826]

FX The idea to deploy OBSs on the 2004 NPAL experiment was conceived at a
workshop held at Woods Hole in March 2004 (Odom and Stephen, 2004). The
LOAPEX source deployments, the moored DVLA receiver deployments, and
some post-cruise data reduction and analysis were funded by the Office
of Naval Research under Award Nos. N000141403-1-0181, N00014-03-1-0182,
and N00014-06-1-0222. Additional post-cruise analysis support was
provided to RAS through the Edward W. and Betty J. Scripps Chair for
Excellence in Oceanography. The OBS/Hs used in the experiment were
provided by Scripps Institution of Oceanography under the U.S. National
Ocean Bottom Seismic Instrumentation Pool
(SIO-OBSIP-http://www.obsip.org). To cover the costs of the OBS/H
deployments funds were paid to SIO-OBSIP from the National Science
Foundation and from the Woods Hole Oceanographic Institution Deep Ocean
Exploration Institute. The OBS/H data are archived at the IRIS
(Incorporated Research Institutions for Seismology) Data Management
Center.

TI Coherence function for the stochastic scattering by a time-varying,
slightly rough, acoustically soft surface
SO JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA
LA English
DT Article
ID SOUND; OCEAN
AB Approximations for the coherence function of the random acoustic field scattered by a moving rough surface are extracted from a second-order perturbation expansion. The statistically rough surface is characterized by a simple, wide-sense stationary autocorrelation function that exhibits temporal and spatial dispersive behavior in terms of three parameters: the acoustically-small mean-square surface height, a correlation length, and a group velocity. Excitation is provided by the quintessential obliquely-incident time-harmonic plane-wave. Asymptotic evaluation of Fourier integral representations of the stochastic field yields expressions for the coherence function that explicitly display the dependence upon the space and time coordinates and their interaction via the geometrical parameters of the rough surface.

STABILITY; DEFECTS; FRACTURES
AB Recurrent anterior shoulder instability may result from a spectrum of overlapping, often coexistent factors, one of which is glenoid bone loss. Untreated, glenoid bone loss may lead to recurrent instability and poor patient satisfaction. Recent studies suggest that the glenoid rim is altered in up to 90% of shoulders with recurrent instability, thus underscoring the need for careful diagnosis, quantification, and preoperative evaluation. Biomechanical and clinical studies offer criteria that may be used in both primary and revision settings to judge whether shoulder stability is compromised by a bony defect. Along with patient activity level, these criteria can help guide the surgeon in selecting treatment options, which range from nonsurgical care to isolated soft-tissue repair as well as various means of bony reconstitution.

AB Exercise is an important component of a healthy lifestyle and, as such, is recommended during pregnancy. However, the response to exercise of both the expectant mother and fetus varies depending on the fitness level of the woman. The response to exercise is also affected by the known musculoskeletal and physiologic changes associated with pregnancy, such as increased ligament laxity, weight gain, change in the center of gravity, and carpal tunnel syndrome. Although the physiologic responses of the pregnant woman and fetus have been well studied, the literature contains comparatively few studies investigating response to exercise. When performed properly, activities such as aerobics, impact and nonimpact activities, resistance training, and swimming may be beneficial during pregnancy.

AB As part of the Coupled Boundary Layers Air-Sea Transfer (CBLAST)-Hurricane program, flights were conducted to directly measure turbulent fluxes and turbulence properties in the high-wind boundary layer of hurricanes between the outer rainbands. For the first time, vertical profiles of normalized momentum fluxes, sensible heat and humidity fluxes, and variances of three-dimensional wind velocities and specific humidity are presented for the hurricane boundary layer with surface wind speeds ranging from 20 to 30 m s(-1). The turbulent kinetic energy budget is estimated, indicating that the shear production and dissipation are the major source and sink terms, respectively. The imbalance in the turbulent kinetic energy budget indicates that the unmeasured terms, such as horizontal advection, may be important in hurricane boundary layer structure and dynamics. Finally, the thermodynamic boundary layer height, estimated based on the virtual potential temperature profiles, is roughly half of the boundary layer height estimated from the momentum flux profiles. The latter height where momentum and humidity fluxes tend to vanish is close to that of the inflow layer and also of the maximum in the tangential velocity profiles.

AB The pitting corrosion resistance of surface-modified 316L austenitic stainless steel and N08367 (a "superaustenitic" stainless steel) were evaluated in 0.6 M NaCl solutions and compared to untreated samples of the same materials. The surface modification process used to treat the surfaces was a low-temperature carburization technology termed "low-temperature colossal supersaturation" (LTCSS). The process typically produces surface carbon concentrations of similar to 15 at. pct without the formation of carbides. The pitting potential of the LTCSS-treated 316L stainless steel in the NaCl solution substantially increased compared to untreated 316L stainless steel, while the pitting behavior of the LTCSS-treated N08367 was unchanged compared to the untreated alloy.

AB The needs of individuals with chronic diseases or disabilities are similar whether within military or civilian communities. With finite resources and the continuing global war on terrorism, military treatment facilities (MTFs) may find collaborative, multidisciplinary, continuing education efforts with community agencies invaluable. Collaborative efforts that bring military and civilian communities together can result in innovative programs that offer cost-effective high-quality information to enhance the knowledge and skill level of military families, providers, and other professionals who provide services and care for military eligible beneficiaries. This article addresses the development and implementation of two major multidisciplinary disease management conferences at Naval Medical Center Portsmouth (NMCP), Virginia. It provides an overview of lessons learned in the areas of preplanning, team building, program development, implementation, and evaluation. Despite challenges, tremendous benefits may be reaped from efforts to include diverse target populations from military and civilian communities.

TI Physician Attire in the Military Setting: Does It Make a Difference to
Our Patients?
SO MILITARY MEDICINE
LA English
DT Article
ID WHITE COATS; ATTITUDES; DOCTORS; CARE
AB Objective: To examine patient preference regarding physician attire and whether perception of medical competence was influenced by the physician's clothing style. Methods: New patients presenting to the OB/GYN clinic at the Naval Medical Center Portsmouth were asked to complete a survey regarding patient preference for physcian attire and any effect on their comfort or confidence in the physician. Results: Surveys were collected over a 2-month period. Completed surveys (328) were analyzed with the following results: 86% had no preference whether the physician wore a white coat, 61% preferred scrubs, 13% were uncomfortable talking to a doctor about general topics, and 16% were uncomfortable talking about sexual, psychological, or personal topics based on physician attire. In a comparison between active duty women and dependent wives, a significantly greater number of dependent wives reported the physician attire having no influence on their comfort level discussing general topics with their physician (p = 0.037) or about sexual, psychological, or personal topics (p = 0.035). No difference was seen between groups in the preference to wear a white coat (p = 0.196) or other attire (p = 0.088) or of an influence of the doctors' clothing on the patient's confidence in the doctors' abilities (p = 0.063). Conclusion: Overall, female patients in a military setting do not have a preference for specific physician attire and attire does not influence their perception of the doctor's competence. However, a greater number of dependent wives report physician attire has no influence on their comfort level discussing both general and personal topics when compared with active duty women. This finding highlights the unique role of the military uniform in the eyes of active duty women and their potential discomfort in discussing personal medical issues with a physician in military uniform.

We present a case of a U.S. Marine in Iraq who was noted to have intermittent and unexplained behavioral changes. The patient had repeatedly denied alcohol use, but during a second medical evacuation from theater, a blood alcohol level was drawn. Results did not come back fast enough to prevent the evacuation, but did eventually confirm that he was intoxicated. Mouthwash was the source. This case illustrates the importance of screening for alcohol abuse and intoxication even in situations in which conventional use of alcohol is not anticipated.

AB This study compares six different guidance products for targeted observations over the northwest Pacific Ocean for 84 cases of 2-day forecasts in 2006 and highlights the unique dynamical features affecting the tropical cyclone (TC) tracks in this basin. The six products include three types of guidance based on total-energy singular vectors (TESVs) from different global models, the ensemble transform Kalman filter (ETKF) based on a multimodel ensemble, the deep-layer mean (DLM) wind variance, and the adjoint-derived sensitivity steering vector (ADSSV). The similarities among the six products are evaluated using two objective statistical techniques to show the diversity of the sensitivity regions in large, synoptic-scale domains and in smaller domains local to the TC. It is shown that the three TESVs are relatively similar to one another in both the large and the small domains while the comparisons of the DLM wind variance with other methods show rather low similarities. The ETKF and the ADSSV usually show high similarity because their optimal sensitivity usually lies close to the TC. The ADSSV, relative to the ETKF, reveals more similar sensitivity patterns to those associated with TESVs. Three special cases are also selected to highlight the similarities and differences among the six guidance products and to interpret the dynamical systems affecting the TC motion in the northwestern Pacific. Among the three storms studied, Typhoon Chanchu was associated with the subtropical high, Typhoon Shanshan was associated with the midlatitude trough, and Typhoon Durian was associated with the subtropical jet. The adjoint methods are found to be more capable of capturing the signal of the dynamic system that may affect the TC movement or evolution than are the ensemble methods.

AB Historical records of aviation turbulence encounters above Greenland are examined for the period from 2000 to 2006. These data identify an important flow regime that contributes to the occurrence of aircraft turbulence encounters, associated with the passage of surface cyclones that direct easterly or southeasterly flow over Greenland's imposing terrain. The result of this incident flow is the generation of mountain waves that may become unstable through interactions with the background directional wind shear. It is shown that this regime accounted for approximately 40% of the significant turbulent events identified in the 7-yr database. In addition, two specific cases from the database are examined in more detail using a high-resolution mesoscale model. The model simulations highlight the important role of three-dimensional gravity wave-critical level interactions and demonstrate the utility of high-resolution forecasts in the prediction of such events.

AB We report a direct correlation between carrier mobility and Raman topography of epitaxial graphene (EG) grown on silicon carbide (SiC). We show the Hall mobility of material on SiC(0001) is highly dependent on thickness and monolayer strain uniformity. Additionally, we achieve high mobility epitaxial graphene (18100 cm(2)/(V s) at room temperature) on SiC(000 (1) over bar) and show that carrier mobility depends strongly on the graphene layer stacking.

ID INTENTIONAL NEGLECT; STROKE; REHABILITATION; RESPONSES
AB Monocular patching might improve perceptual-attentional, not motor-intentional deficits in a patient with chronic post-stroke left spatial neglect. Performing a line-cancellation task, his omission errors were associated with a perceptual-attentional 'where' deficit, while perseverative errors were associated with 'aiming' motor-intentional bias. Contralesional patching had no effect on the omissions (p = .871), whereas ipsilesional patching reduced left-sided omissions compared with the unpatched condition(p = .016). Neither patching condition altered perseverative errors. Further research is needed to examine whether targeting treatments to spatial neglect symptoms (omissions, perseveration) results in improved outcomes.

DE Angiographically negative diffuse subarachnoid hemorrhage; Clinical

ID ANGIOGRAM
AB To identify prognostic factors for vasospasm, hydrocephalus, and clinical outcomes in patients with angiographically negative, non-traumatic, diffuse subarachnoid hemorrhage (d-SAH).
Retrospective review of patients who experienced angiographically negative SAH at our institution over the past 6 years was undertaken. The patients were stratified based on grade at presentation, severity, and pattern of SAH on initial non-enhanced, computed tomography (CT) of the head into perimesencephalic and diffuse subtypes. The patients were further differentiated based on the development of vasospasm, hydrocephalus and required treatments, and clinical outcomes. Patients were excluded if a causative lesion was discovered subsequently.
Ninety-four patients with angiographically negative SAH were identified. A total of 31 patients were considered to have the perimesencephalic (p-SAH) subtype, while 63 patients fit criteria for the diffuse (d-SAH) subtype. Compared to the p-SAH subtype, those patients with d-SAH subtype had significantly higher risk for complications related to SAH with an increased incidence of hydrocephalus (50.8% vs. 9.6%), requirement for external ventricular drainage (41% vs. 9.6%), and for the hydrocephalus requiring eventual permanent cerebrospinal fluid diversion (20.6% vs. 0%). Patients with d-SAH were also at an increased risk for symptomatic vasospasm (28.6% vs. 9.6%). Ultimately, only 76% of d-SAH patients achieved complete recovery and independent living, compared to 96.7% of p-SAH patients.
The angiographically negative d-SAH pattern is associated with worse presentations and outcome. These patients are at increased risk for vasospasm and hydrocephalus requiring aggressive treatment and should therefore be cared for with a higher level of surveillance.

Then using the weak convergence approach, Laplace principle for solutions of the stochastic GOY model is established in certain Polish space. Thus a Wentzell-Freidlin type large deviation principle is established utilizing certain results by Varadhan and Bryc.

AB BACKGROUND: Anaphylaxis associated with breast-feeding is a rare but potentially life-threatening event.
CASE: This woman reported anaphylaxis with three previous pregnancies while breast-feeding. With her fourth pregnancy she was treated with corticosteroids and antihistamines after delivery. Despite treatment, she developed urticaria, facial edema, and throat tightening, less severe than prior episodes. Her symptoms resolved with epinephrine and antihistamine but recurred with subsequent breast-feeding. On postpartum day 4 she had no symptoms while breast-feeding.
CONCLUSION: Three cases of postpartum breast-feeding anaphylaxis have been reported. Although the pathophysiology is unclear, it may involve the decrease in progesterone and rise of prolactin causing mast cell degranulation. Avoidance of nonsteroidal antiinflammatories and prophylaxis with corticosteroids and antihistamines may offer the best protection. (Obstet Gynecol 2009;114:415-6)

AB Measurements and simulations of a dual gas-cell system, which uses Raman scattering to convert infrared laser radiation from 1064 to 1560 nm, are presented. The cells contain deuterium at a pressure of similar to 25 atm. A beamsplitter is used to distribute the energy from the YAG laser between the seed and pump cells. The laser light is focused into the seed cell, which generates a lower-power, backward-propagating, pulse. This seed pulse and a laser pulse counterpropagate in the pump cell to generate a stronger 1560-nm pulse. The goal is to create a single pulse without any shorter pulses or oscillations. Simulation results are presented, which indicate that a beamsplitter directing 25% of the laser energy into the seed cell and the rest into the pump cell is optimal for 1560-nm generation. Laboratory testing of a dual-cell system using a 32% beamsplitter shows the generation of a 1560-nm pulse with 250 mJ/pulse with an efficiency of 35%.

AB Using x-ray diffraction and beam-foil spectroscopy, we have determined precise wavelengths for Lyman alpha(1) and Lyman alpha(2) in hydrogenic germanium of 1.166 993 8 +/- 33 +/- 169 and 1.172 433 6 +/- 39 +/- 170 angstrom. Hydrogenic germanium Ge31+ 1s-2p(3/2) and 1s-2p(1/2) Lamb shifts are measured to be 66 080 +/- 237 +/- 1121 and 67 169 +/- 281 +/- 1237 cm(-1), respectively. This 14 ppm measurement of the wavelengths thus provides a 1.8% measurement of the 2p-1s Lamb shift and is an improvement by a factor of 3 over previous work. Fitting the full two-dimensional dispersion relation, including Balmer and Lyman series, limits random and systematic correlation of parameters. Dominant systematics are due to diffraction parameters including crystal thickness and alignment, differential Doppler shifts due to the variable location of spectral emission downstream of the beam-foil target, and dielectronic, 2s-1s, and 4f-2p satellites. Models developed are applicable to all relativistic plasma modeling in beam-foil spectroscopy at accelerators. The technique also reports the germanium 2p(3/2)-2p(1/2) fine structure as 397 617 +/- 251 +/- 512 cm(-1), representing a 0.14% measurement of the fine structure and a 71% measurement of the QED contribution to the hydrogenic germanium fine structure, an improvement of a factor of 6 over previous work. We also report a precise measurement of heliumlike resonances and fine structure.

From these measurements we characterize the low-energy excitations, revealing that the Fermi surface is reconstructed in the antiferromagnetic state, but leaving itinerant electrons in its wake. The present measurements are consistent with a conventional band folding picture of the antiferromagnetic ground state, placing important limits on the topology and size of the Fermi surface.

AB It is shown through experimental mapping of surface-enhanced Raman scattering (SERS) from dielectric core nanowires exposed to benzene thiol that any dielectric substrate plays a critical role in the SERS enhancement. Theoretical calculations of the plasmonic enhancement using finite element methods confirms the role that the substrate plays in increasing the intensity and spatial extent of the SERS enhancement. It is shown that because of the cylindrical shape of the nanowires, significant SERS hot spots form not only between crossed nanowires but also at the point of contact between the nanowires and the substrate on which they are placed. This result also applies to any structure whose geometry results in a point or line contact with an underlying substrate.

AB We present a systematic analysis of two-pion interferometry in Au+Au collisions at s(NN)=62.4 GeV and Cu+Cu collisions at s(NN)=62.4 and 200 GeV using the STAR detector at the Relativistic Heavy Ion Collider (RHIC). The multiplicity and transverse momentum dependences of the extracted correlation lengths (radii) are studied. The scaling with charged particle multiplicity of the apparent system volume at final interaction is studied for the RHIC energy domain. The multiplicity scaling of the measured correlation radii is found to be independent of colliding system and collision energy.

AB The Long Wavelength Array (LWA) will be a new multipurpose radio telescope operating in the frequency range 10-88 MHz. Upon completion, the LWA will consist of 53 phased array "stations" distributed over a region about 400 km in diameter in the state of New Mexico. Each station will consist of 256 pairs of dipole-type antennas whose signals are formed into beams, with outputs transported to a central location for high-resolution aperture synthesis imaging. The resulting image sensitivity is estimated to be a few millijanskys (5 sigma, 8 MHz, two polarizations, 1 h, zenith) in 20-80 MHz; with resolution and field of view of (8 '', 8 degrees) and (2 '', 2 degrees) at 20 and 80 MHz, respectively. Notable engineering features of the instrument, demonstrated in this paper, include Galactic-noise limited active antennas and direct sampling digitization of the entire tuning range. This paper also summarizes the LWA science goals, specifications, and analysis leading to top-level design decisions.

AB The Square Kilometre Array (SKA) will be an ultrasensitive radio telescope, built to further the understanding of the most important phenomena in the Universe, including some pertaining to the birth and eventual death of the Universe itself. Over the next few years, the SKA will make the transition from an early formative to a well-defined design. This paper outlines how the scientific challenges are translated into technical challenges, how the application of recent technology offers the potential of affordably meeting these challenges, and how the choices of technology will ultimately be made. The SKA will be an array of coherently connected antennas spread over an area about 3000 km in extent, with an aggregate antenna collecting area of up to 106m(2) at centimeter and meter wavelengths. A key scientific requirement is the ability to carry out sensitive observations of the sky over large areas (surveys). The "survey speed" of the SKA will be enabled by the application of the most up-to-date signal-processing technology available. The SKA science impact will be widely felt in astroparticle physics and cosmology, fundamental physics, galactic and extragalactic astronomy, solar system science, and astrobiology.

AB Classical Hall-Petch relation for large grained polycrystals is usually derived using the model of dislocation pile-up first investigated mathematically by Nabarro and coworkers. In this paper the mechanical properties of nanocrystalline materials are reviewed, with emphasis on the fundamental physical mechanisms involved in determining yield stress. Special attention is paid to the abnormal or 'inverse' Hall-Petch relationship, which manifests itself as the softening of nanocrystalline materials of very small (less than 12 nm) mean grain sizes. It is emphasized that modeling the strength of nanocrystalline materials needs consideration of both dislocation interactions and grain-boundary sliding (presumably due to Coble creep) acting simultaneously. Such a model appears to be successful in explaining experimental results provided a realistic grain size distribution is incorporated into the analysis. Masumura et al. [Masumura RA, Hazzledine PM, Pande CS. Acta Mater 1998;46:4527] were the first to show that the Hall-Petch plot for a wide range of materials and mean grain sizes could be divided into three distinct regimes and also the first to provide a detailed mathematical model of Hall-Petch relation of plastic deformation processes for any material including fine-grained nanocrystalline materials. Later developments of this and related models are briefly reviewed.
Prof. Frank Nabarro was a physicist by training, a metallurgist by profession and a genius by nature, blessed with a unique ability to treat everyone as his equal. During his later years he was very much interested in the mechanical properties of nanocrystalline materials. This review on that topic is our contribution to the special issue of Progress in Materials Science honoring him. Published by Elsevier Ltd.

AB Small-scale detonation experiments were conducted in a controlled atmosphere chamber to investigate the post-detonation reactivity of a fuel-rich, plastic bonded explosive. The atmosphere surrounding these 20 g explosive charges was varied in oxygen content from 0.2 to 100% with the total pressure held constant at 101 kPa. The performance of this small-scale explosive charge is sensitive to the changing atmospheric conditions, perhaps more so than a larger charge size, due to burning inefficiencies corresponding to a scaling effect (increased surface area to volume ratio). Time-resolved optical emission spectroscopy was used to contrast the dependence of the post-detonation combustion properties on external oxygen content. The dominant near-ultraviolet and visible emission features evolve from aluminum (Al) and aluminum monoxide (AlO) when oxygen is present. The time evolution of AlO emission was used to estimate the aluminum particle burning times, which lengthen from 6 to 31 mu s as the oxygen content is reduced from 100 to 1%. The absence of AlO spectral features below 1% oxygen levels imply that the emission spectroscopy applied to this detonation environment is most sensitive to the aerobic component of the post-detonation combustion, Pressure and optical pyrometry measurements recorded during the same experiments exhibit the strong dependence of the early time energy release oil the oxygen content in the surrounding atmosphere. Numerical simulations of the detonation and subsequent multiphase flow expansion predict the position of the fuel particles to extend beyond the detonation products and, in some cases, beyond the shock front during the timescales covered in these experiments, stressing the importance of mixing with ambient oxygen for early combustion to occur.

ID EPR DOSIMETRY; RADIATION
AB The results of electron paramagnetic resonance (EPR) measurements in irradiated fingernails are presented. In total, 83 samples of different fingernails were studied. Five different groups of samples were selected based on the collection time of fingernail samples, their level of mechanical stress, and the number and size of clippings: (1) recently (< 24 h) cut, irradiated and measured with EPR without any treatment of samples, and with rigorous control of size and number of clippings (stressed-fresh, controlled); (2) recently (< 24 h) cut, irradiated and measured with EPR after application of a special treatment (10 min of water soaking, 5 min of drying time) to reduce the mechanical stress caused by cutting the samples, and with rigorous control of size and number of clippings (unstressed-fresh, controlled); (3) previously (> 24 h) cut, stored at room temperature, additionally cut into small pieces immediately prior to study, irradiated and measured with EPR without any treatment of samples, and with rigorous control of size and number of clippings (stressed-old, controlled); (4) previously (> 24 h) cut, stored at room temperature, additionally cut into small pieces immediately prior to the study, irradiated and measured with EPR after application of a special treatment to reduce mechanical stress caused by cut, and with rigorous control of size and number of clippings (unstressed-old, controlled); and (5) recently (< 24 h) cut, irradiated and measured with EPR after application of a special treatment to reduce the mechanical stress caused by cut, and without rigorous control of size and number of clippings (unstressed-fresh, uncontrolled). Except for the fifth selected group, variability of the dose dependence inside all groups was found to be not statistically significant, although the variability among the different groups was significant. Comparison of the mean dose dependences obtained for each group allowed selection of key factors responsible for radiation sensitivity (dose response per unit of mass and dose) and the shape of dose dependence in fingernails. The major factor responsible for radiation sensitivity of fingernails was identified as their water content, which can affect radiation sensitivity up to 35%. The major factor responsible for the shape of the radiation sensitivity was identified as the mechanical stress. At a significant level of mechanical stress, the shape of the dose dependence is linear in the studied dose range (< 20 Gy), and in lesser-stressed samples it is of an exponential growth including saturation, which depends on the degree of mechanical stress. In view of the findings, recommendations are discussed and presented for the appropriate protocol for EPR dose measurements in fingernails.

AB Bacteriophage T4 nanoparticles possess characteristics that make them ideal candidates as materials for sensors, particularly as sensor probes. Their surface can be modified, either through genetic engineering or direct chemical conjugation to display functional moieties such as antibodies or other proteins to recognize a specific target. However, in order for T4 nanoparticles to be utilized as a sensor probe, it is necessary to understand and control the variables that determine their assembly and organization on a surface. The aim of this work is to discuss some of variables that we have identified as influencing the behavior of T4 nanoparticles on surfaces. The effect of pH, ionic strength, substrate characteristics, nanoparticle concentration and charge was addressed qualitatively using atomic force microscopy (AFM).

AB Interstellar material (ISMa) is observed both inside and outside of the heliosphere. Relating these diverse sets of ISMa data provides a richer understanding of both the interstellar medium and the heliosphere. The galactic environment of the Sun is dominated by warm, low-density, partially ionized interstellar material consisting of atoms and dust grains. The properties of the heliosphere are dependent on the pressure, composition, radiation field, ionization, and magnetic field of ambient ISMa. The very low-density interior of the Local Bubble, combined with an expanding superbubble shell associated with star formation in the Scorpius-Centaurus Association, dominate the properties of the local interstellar medium (LISM). Once the heliosphere boundaries and interaction mechanisms are understood, interstellar gas, dust, pickup ions, and anomalous cosmic rays inside of the heliosphere can be directly compared to ISMa outside of the heliosphere. Our understanding of ISMa at the Sun is further enriched when the circumheliospheric interstellar material is compared to observations of other nearby ISMa and the overall context of our galactic environment. The IBEX mission will map the interaction region between the heliosphere and ISMa, and improve the accuracy of comparisons between ISMa inside and outside the heliosphere.

AB Heat and hydration may not be the first considerations of tournament directors, coaches, and athletes, when preparing for tennis. However, health risks and performance decrements are associated with both. The demands of tennis, particularly during multiday tournaments, predispose players to increased core body temperature and large fluid losses. This combination of factors can lead to decreased performance and exertional heat illnesses such as heat cramps, heat syncope, or heat exhaustion. By identifying individual fluid and salt needs, designing a replacement plan, and reducing core body temperature during and between matches, athletes can optimize performance while minimizing risk of heat illness.

AB A simple hydrothermal growth process was developed to deposit conformal manganese oxide nanospheres with a diameter of 10 to 20 nm on mesoporous carbon paper. The coating of nanospheres increased the cyclic-voltammogramic response of carbon paper by a factor of 5 with a slight dependence on the scan rate. For comparison, a related chemistry was also developed to fabricate a dense packing of manganese oxide nanorods with a diameter of 20 to 50 nm and a length of approximately 500 nm. The nanorods also increased the cyclic-voltammogramic response of carbon paper but only by a factor of approximately 3.

AB Background: Adverse radiation effects are a known complication after the use of SRS for AVMs, although it is difficult to predict which patients will manifest with these side effects. Treatment of swelling due to ARE is usually medical, but refractory cases may require surgical decompression.
Case Description: This report presents a case of a patient who experienced AREs after SRS (edema, headaches, and nausea) that failed to respond to steroid treatment but was successfully treated with HBO. The treatment characteristics of this and of 5 other cases of radiation injury after SRS for AVM managed with HBO therapy are reviewed, and the pathophysiology is discussed.
Conclusion: Hyperbaric oxygen therapy provides a therapeutic option to treat AREs following SRS of cerebral AVMs. (C) 2009 Published by Elsevier Inc.

AB Using a fully kinetic 2D Fokker-Planck model, the generation and evolution of ion density perturbations from nonuniform laser deposition in a plasma slab have been studied. It is found that significant smoothing of the ion density perturbations from nonuniform optically smoothed single beam laser deposition can be achieved on hydrodynamic times scales over a range of scale sizes. In addition, it is observed that the Fokker-Planck model predicts more smoothing than the hydrodynamic Spitzer model.

AB In situ cloud condensation nuclei (CCN) measurements were obtained in the boundary layer over Houston, Texas, during the 2006 Gulf of Mexico Atmospheric Composition and Climate Study (GoMACCS) campaign onboard the CIRPAS Twin Otter. Polluted air masses in and out of cloudy regions were sampled for a total of 22 flights, with CCN measurements obtained for 17 of these flights. In this paper, we focus on CCN closure during two flights, within and downwind of the Houston regional plume and over the Houston Ship Channel. During both flights, air was sampled with particle concentrations exceeding 25,000 cm(-3) and CCN concentrations exceeding 10,000 cm(-3). CCN closure is evaluated by comparing measured concentrations with those predicted on the basis of measured aerosol size distributions and aerosol mass spectrometer particle composition. Different assumptions concerning the internally mixed chemical composition result in average CCN overprediction ranging from 3% to 36% (based on a linear fit). It is hypothesized that the externally mixed fraction of the aerosol contributes much of the CCN closure scatter, while the internally mixed fraction largely controls the overprediction bias. On the basis of the droplet sizes of activated CCN, organics do not seem to impact, on average, the CCN activation kinetics.

AB The main goal of this paper is to identify the molecular origins of two secondary relaxations observed in mechanical as well as in dielectric spectra in polysaccharides, including cellulose, and starches, such as pullulan and dextran. This issue has been actively pursued by many research groups, but consensus has not been reached. By comparing experimental data of monosaccharides, disaccharides, and polysaccharides, we are able to make conclusions on the origins of two secondary relaxations in poly saccharides. The faster secondary relaxations of polysaccharides are similar to the faster secondary relaxations of mono-, di-, and oligosaccharides. These include comparable relaxation times and activation energies in the glassy states, and also all the faster secondary relaxations have larger dielectric strengths than the slower secondary relaxation. The similarities indicate that the faster secondary relaxations in the polysaccharides have the same origin as that in mono-, di-, and oligosaccharides. Furthermore, since the relaxation time of the faster secondary relaxation in several mono- and disaccharides was found to be insensitive to applied pressure, the faster secondary relaxations of the polysaccharides are identified as internal motions within their monomeric units. The slower secondary relaxations in polysaccharides also have similar characteristics to those of the slower secondary relaxations of the disaccharides (maltose, cellobiose, sucrose, and trehalose), which indicates the analogous motions govern the slower process in these two groups of carbohydrates. Earlier we have shown in disaccharides that the rotation of the monomeric units around the glycosidic bond is responsible for this process. The same motion can occur in polysaccharides in the form of a local chain rotation, These motions involve the whole molecule in disaccharides and a local segment in polysaccharides. It is intermolecular in nature (with relaxation time pressure dependent, as found before in a disaccharide), and hence, it is the precursor of the structural (x-relaxation. These results lead us to identify the slower secondary relaxation of the polysaccharides as the Johari-Goldstein beta-relaxation, which is supposedly a universal and fundamental process in all glass-forming Substances.

AB The nature of the background emission in surface enhanced Raman scattering is elucidated. A simple group of benzene ring based thiols is used to demonstrate the introduction of optically active interface states upon adsorption on Ag coated dielectric core nanowires. Excellent agreement is obtained with density of state (DOS) calculations for benzenethiol adsorbed on Ag. We also present evidence for photoluminescence enhanced resonant Raman scattering as an important component of surface enhanced Raman scattering. (C) 2009 Elsevier B. V. All rights reserved.

TI Microwave response of superconducting pnictides: extended s(+/-)

ID HIGH-TC-SUPERCONDUCTORS; IMPURITY SCATTERING; CONDUCTIVITY; DENSITY
AB We consider a two-band superconductor with relative phase pi between the two order parameters as a model for the superconducting state in ferropnictides. Within this model we calculate the microwave response and the NMR relaxation rate. The influence of intra- and interband impurity scattering beyond the Born and unitary limits is taken into account. We show that, depending on the scattering rate, various types of power law temperature dependences of the magnetic field penetration depth and the NMR relaxation rate at low temperatures may take place.

AB The influence of highly active antiretroviral therapy (HAART) upon hepatitis B virus (HBV) vaccine responses in HIV-infected individuals is unclear. After classification of vaccinees as non-responders (HBsAb <10IU/L) or responders (HBsAb >= 10IU/L) in our HIV cohort, multivariate logistic regression was used to assess factors associated with subsequent vaccine response. Of 626 participants vaccinated from 1988 to 2005, 217 (35%) were vaccine responders. Receipt of >= 3 doses of vaccine (OR 1.83, 95% CI 1.24-2.70), higher CD4 count at vaccination (OR 1.09, 95% CI 1.05-1.13 per 50 cells/mu l increase), and use of HAART (OR 2.37, 95% CI 1.56-3.62) were all associated with increased likelihood of developing a response. However, only 49% of those on HAART at last vaccination responded, and 62% of those on HAART, with CD4 count >= 350, and HIV RNA <400 copies/mL responded. Compared to those on HAART with CD4 count >= 350, those not on HAART with CD4 count >= 350 had significantly reduced odds of developing a vaccine response (OR 0.47, 95% CI 0.30-0.70). While HAART use concurrent with HBV immunization was associated with increased probability of responding to the vaccine, the response rate was low for those on HAART. These data provide additional evidence of HAART benefits, even in those with higher CD4 counts, but also highlight the need for improving HBV vaccine immunogenicity. (C) 2009 Elsevier Ltd.

TI A solar storm observed from the Sun to Venus using the STEREO, Venus

AB The suite of SECCHI optical imaging instruments on the STEREO-A spacecraft is used to track a solar storm, consisting of several coronal mass ejections (CMEs) and other coronal loops, as it propagates from the Sun into the heliosphere during May 2007. The 3-D propagation path of the largest interplanetary CME (ICME) is determined from the observations made by the SECCHI Heliospheric Imager (HI) on STEREO-A (HI-1/2A). Two parts of the CME are tracked through the SECCHI images, a bright loop and a V-shaped feature located at the rear of the event. We show that these two structures could be the result of line-of-sight integration of the light scattered by electrons located on a single flux rope. In addition to being imaged by HI, the CME is observed simultaneously by the plasma and magnetic field experiments on the Venus Express and MESSENGER spacecraft. The imaged loop and V-shaped structure bound, as expected, the flux rope observed in situ. The SECCHI images reveal that the leading loop-like structure propagated faster than the V-shaped structure, and a decrease in in situ CME speed occurred during the passage of the flux rope. We interpret this as the result of the continuous radial expansion of the flux rope as it progressed outward through the interplanetary medium. An expansion speed in the radial direction of similar to 30 km s(-1) is obtained directly from the SECCHI-HI images and is in agreement with the difference in speed of the two structures observed in situ. This paper shows that the flux rope location can be determined from white light images, which could have important space weather applications.

AB We present a technique for generation of miniature plasma lens system that can be used for focusing and collimating a high intensity femtosecond laser pulse. The plasma lens was created by a nanosecond laser, which ablated a capillary entrance. The spatial configuration of the ablated plasma focused a high intensity femtosecond laser pulse. This configuration offers versatility in the plasma lens small f-number for extremely tight focusing of high power lasers with no damage threshold restrictions of regular optical components.

AB We present stereoscopic reconstructions of the location and inclination of polar plumes of two data sets based on the two simultaneously recorded images taken by the EUVI telescopes in the SECCHI instrument package onboard the Solar TErrestrial RElations Observatory spacecraft. The 10 plumes investigated show a superradial expansion in the coronal hole in three dimensions (3D) which is consistent with the two-dimensional results. Their deviations from the local meridian planes are rather small with an average of 6 degrees..47. By comparing the reconstructed plumes with a dipole field with its axis along the solar rotation axis, it is found that plumes are inclined more horizontally than the dipole field. The lower the latitude is, the larger is the deviation from the dipole field. The relationship between plumes and bright points has been investigated and they are not always associated. For the first data set, based on the 3D height of plumes and the electron density derived from SUMER/SOHO Si VIII line pair, we found that electron densities along the plumes decrease with height above the solar surface. The temperature obtained from the density scale height is 1.6-1.8 times larger than the temperature obtained from Mg IX line ratios. We attribute this discrepancy to a deviation of the electron and the ion temperatures. Finally, we have found that the outflow speeds studied in the O VI line in the plumes corrected by the angle between the line of sight and the plume orientation are quite small with amaximum of 10 km s(-1). It is unlikely that plumes are a dominant contributor to the fast solar wind.

AB The first three months of sky-survey operation with the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope reveal 132 bright sources at |b| > 10 degrees with test statistic greater than 100 ( corresponding to about 10 sigma). Two methods, based on the CGRaBS, CRATES, and BZCat catalogs, indicate high-confidence associations of 106 of these sources with known active galactic nuclei (AGNs). This sample is referred to as the LAT Bright AGN Sample (LBAS). It contains two radio galaxies, namely, Centaurus A and NGC 1275, and 104 blazars consisting of 58 flat spectrum radio quasars (FSRQs), 42 BL Lac objects, and 4 blazars with unknown classification. Four new blazars were discovered on the basis of the LAT detections. Remarkably, the LBAS includes 10 high-energy-peaked BL Lacs (HBLs), sources which were previously difficult to detect in the GeV range. Another 10 lower-confidence associations are found. Only 33 of the sources, plus two at |b| < 10 degrees, were previously detected with Energetic Gamma-Ray Experiment Telescope( EGRET), probably due to variability. The analysis of the gamma-ray properties of the LBAS sources reveals that the average GeV spectra of BL Lac objects are significantly harder than the spectra of FSRQs. No significant correlation between radio and peak gamma-ray fluxes is observed. Blazar log N-log S distributions and luminosity functions are constructed to investigate the evolution of the different blazar classes, with positive evolution indicated for FSRQs but none for BL Lacs. The contribution of LAT blazars to the total extragalactic gamma-ray intensity is estimated.

AB Measurements of the temperature and density structure of the solar corona provide critical constraints on theories of coronal heating. Unfortunately, the complexity of the solar atmosphere, observational uncertainties, and the limitations of current atomic calculations, particularly those for Fe, all conspire to make this task very difficult. A critical assessment of plasma diagnostics in the corona is essential to making progress on the coronal heating problem. In this paper, we present an analysis of temperature and density measurements above the limb in the quiet corona using new observations from the EUV Imaging Spectrometer (EIS) on Hinode. By comparing the Si and Fe emission observed with EIS we are able to identify emission lines that yield consistent emission measure distributions. With these data we find that the distribution of temperatures in the quiet corona above the limb is strongly peaked near 1 MK, consistent with previous studies. We also find, however, that there is a tail in the emission measure distribution that extends to higher temperatures. EIS density measurements from several density sensitive line ratios are found to be generally consistent with each other and with previous measurements in the quiet corona. Our analysis, however, also indicates that a significant fraction of the weaker emission lines observed in the EIS wavelength ranges cannot be understood with current atomic data.

AB We performed combined focused ion beam/transmission electron microscopy studies to investigate the chemistry and structure of eight presolar silicate grains that were previously detected by NanoSIMS oxygen isotope mapping of the carbonaceous chondrite Acfer 094. The analyzed presolar silicates belong to the O isotope Groups I/II ((17)O-enriched and (18)O-depleted) and therefore come from 1-2.5 M(circle dot) asymptotic giant branch stars of close-to-solar or slightly lower-than-solar metallicity. Three grains are amorphous, Mg-rich, and show a variable, but more pyroxene-like composition. Most probably, these grains have formed under circumstellar low-temperature conditions below the crystallization temperature. Three grains are Fe-bearing glasses similar to the "glass with embedded metal and sulfides" (GEMS) grains found in interplanetary dust particles. However, two of the meteorite GEMS grains from this study lack comparatively large (greater than or similar to 20 nm) Fe-rich inclusions and have sulfur contents <1 at.%, which is different than observed for the majority of GEMS grains. These grains likely condensed under strong non-equilibrium conditions from an Si-enriched gas. One olivine is characterized by a crystalline core and an amorphous, more Fe-rich rim, which is probably the result of interstellar medium sputtering combined with Mg removal. The detection of another olivine with a relatively high Fe content (Mg# 0.9) shows that circumstellar crystalline silicates are more Fe-rich than astrophysical models usually suggest. The overall predominance of olivine among the crystalline silicate stardust population compared to pyroxene indicates preferential formation or survival of this type of mineral. As pyroxene is indeed detected in circumstellar outflows, it remains to be seen how this result is compatible with astrophysical observations and experimental data.

AB Background: Infants in utero during the terrorist attacks of September 11, 2001 may have been negatively affected by maternal stress. Studies to date have produced contradictory results.
Methods: Data for this retrospective cohort study were obtained from the Department of Defense Birth and Infant Health Registry and included up to 164,743 infants born to active-duty military families. Infants were considered exposed if they were in utero on September 11, 2001, while the referent group included infants gestating in the same period in the preceding and following year (2000 and 2002). We investigated the association of this acute stress during pregnancy with the infant health outcomes of male: female sex ratio, birth defects, preterm birth, and growth deficiencies in utero and in infancy.
Results: No difference in sex ratio was observed between infants in utero in the first trimester of pregnancy on September 11, 2001 and infants in the referent population. Examination of the relationship between first-trimester exposure and birth defects also revealed no significant associations. In adjusted multivariable models, neither preterm birth nor growth deficiencies were significantly associated with the maternal exposure to the stress of September 11 during pregnancy.
Conclusion: The findings from this large population-based study suggest that women who were pregnant during the terrorist attacks of September 11, 2001 had no increased risk of adverse infant health outcomes.

TI Cold atom Raman spectrography using velocity-selective resonances
SO OPTICS EXPRESS
LA English
DT Article
AB We have studied velocity-selective resonances in the presence of a uniform magnetic field and shown how they can be used for rapid, single-shot assessment of the ground state magnetic sublevel spectrum in a cold atomic vapor. Cold atoms are released from a magneto-optical trap in the presence of a small bias magnetic field (approximate to 300 mG) and exposed to a laser field comprised of two phase-locked counterpropagating beams connecting the two ground state hyperfine manifolds. An image of the expanded cloud shows the velocity-selected resonances as distinct features, each corresponding to specific magnetic sublevel, in a direct, intuitive manner. We demonstrate the technique with both Rb-87 and Rb-85, and show the utility of the technique by optically pumping into particular magnetic sublevels. The results are shown to agree with a theoretical model, and are compared to traditional Raman spectroscopy. (C) 2009 Optical Society of America

AB We present a novel method using flow cytometry-fluorescence in situ hybridization (flow-FISH) to detect specific messenger RNA (mRNA) in Suspended cells using locked nucleic acid (LNA)-modified oligonucleotide probes. beta-Actin mRNA was targeted in whole A549 epithelial cells by hybridization with a biotinylated, LNA-modified probe. The LNA bound to beta-actin was then stained using phycoerythrin-conjugated streptavidin and detected by flow cytometry. Shifts in fluorescence signal intensity between the beta-actin LNA probe and a biotinylated, nonspecific control LNA were used to determine optimal conditions for this type of flow-FISH. Multiple conditions for permeabilization and hybridization were tested. and it was found that conditions using 3 mu g/ml of proteinase K for permeabilization and 90 min hybridization at 60 degrees C with buffer containing 50% formamide allow cells containing the LNA-bound mRNA to be detected and differentiated from the control LNA with high confidence (< 14% overlap between Curves). This combined method, called LNA flow-FISH, can be used for detection and quantification of other RNA species as well as for telomerase measurement and detection. (C) 2009 Elsevier Inc.

AB Case Description-3 adult (24- to 43-year-old) Atlantic bottlenose dolphins (Tursiops truncatus) with chronic episodic malaise and inappetence associated with high serum aminotransferase (alanine aminotransferase and aspartate aminotransferase) activities, high serum iron concentration, and serum transferrin saturation > 80% were evaluated.
Clinical Findings-Results of histologic examination of liver biopsy specimens revealed hemosiderosis in all 3 dolphins. Except for chronic lymphocytosis in 1 dolphin, results of extensive diagnostic testing revealed no other abnormalities. For each dolphin, a diagnosis of iron overload of unknown origin was made.
Treatment and Outcome-Phlebotomy treatment was implemented to reduce body stores of iron. Each phlebotomy procedure removed 7% to 17% (1 to 3 L) of estimated blood volume. Treatment consisted of an induction phase of weekly phlebotomy procedures for 22 to 30 weeks, which was complete when serum iron concentration and aminotransferase activities were within reference ranges and serum transferrin saturation was <= 20% or Hct was <= 30%. Total amount of iron removed from each dolphin was 53 to 111 mg/kg (24.1 to 50.5 mg/lb) of body weight. One dolphin required maintenance procedures at 8- to 12-week intervals when high serum iron concentration was detected.
Clinical Relevance-Although the cause of the iron overload and high serum aminotransferase activities remained unknown, phlebotomy treatment successfully resolved the clinicopathologic abnormalities, supporting a role of iron overload in the hepatopathy of the 3 dolphins.

AB This paper describes a rep-rated multibeam KrF laser driver design for the 500 kJ Inertial Fusion test Facility (FTF) recently proposed by NRL, then models its optical pulse shaping capabilities using the ORESTES laser kinetics code. It describes a stable and reliable iteration technique for calculating the required precompensated input pulse shape that will achieve the desired output shape, even when the amplifiers are heavily saturated. It also describes how this precompensation technique could be experimentally implemented in real time on a reprated laser system. The simulations show that this multibeam system can achieve a high fidelity pulse shaping capability, even for a high gain shock ignition pulse whose final spike requires output intensities much higher than the similar to 4 MW/cm(2) saturation levels associated with quasi-cw operation; i.e., they show that KrF can act as a storage medium even for pulsewidths of similar to 1 ns. For the chosen pulse, which gives a predicted fusion energy gain of similar to 120, the simulations predict the FTF can deliver a total on-target energy of 428 kJ, a peak spike power of 385 TW, and amplified spontaneous emission prepulse contrast ratios I(ASE)/I<3 x 10(-7) in intensity and FASE/F < 1.5 x 10(-5) in fluence. Finally, the paper proposes a front-end pulse shaping technique that combines an optical Kerr gate with cw 248 nm light and a 1 mu m control beam shaped by advanced fiber optic technology, such as the one used in the National Ignition Facility (NIF) laser.

TI Anisotropic thermal expansion of RuCo alloys in carbon nanotube matrix
SO JOURNAL OF APPLIED PHYSICS

ID TRANSITION; CO/RU
AB Ru(1-x)Co(x) alloys exhibit hexagonal close packed phase for x <= 0.75. The nanocrystalline samples of Ru(1-x)Co(x) alloys in the presence of carbon nanotubes were prepared by organometallic synthesis and their thermal expansion coefficients were determined using high resolution x-ray diffraction over a temperature range of 25-250 degrees C. The coefficients of linear thermal expansions (CTE) showed anisotropy along the c- and a-axis. The CTE values showed dependence on the composition and varied between 8.8 x 10(-6) / degrees C to 16.1 x 10(-6) / degrees C for c-axis (alpha(parallel to)) and 5.9 x 10(-6) / degrees C to 12.6 x 10(-6) / degrees C for a-axis (alpha(perpendicular to)). These results suggest that RuCo alloys have low thermal expansivity and allow the tailoring of their thermal properties. The radial thermal expansion coefficient (alpha(c)) of carbon nanotube was 26 x 10(-6) / degrees C. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3183914]

TI Galfenol alloying additions and the effects on uniaxial anisotropy
generation
SO JOURNAL OF APPLIED PHYSICS
LA English
DT Article
AB The effects of substitutional and interstitial additions on uniaxial anisotropy (K(uni)) generated via stress annealing were investigated for the galfenol (Fe-Ga) alloy system. Polycrystalline samples prepared via free stand zone melt directional solidification technique were tested under pre- and post-stress annealed conditions in order to ascertain the extent of the built-in stress (T(built-in)) created. Energy based modeling utilizing magnetostriction and magnetization data was used to determine K(uni) and T(built-in). Differential magnetomechanical properties; d(33) and mu(r) were estimated using the same model. Carbon additions from a Fe-C master alloy resulted in K(uni) and T(built-in) values of 12.1 kJ/m(3) and 55 MPa, comparable to the binary system. Low carbon steel additions resulted in a minor decrease in K(uni) to 9.6 kJ/m(3), but still had high T(built-in) values of 54 MPa. Aluminum additions exhibited the largest decreases in K(uni) and T(built-in). A linear decrease in both values was observed as a function of increasing aluminum content. K(uni) values for Fe(81.6)Ga(13.8)Al(4.6) and Fe(81.6)Ga(9.2)Al(9.2) alloys were 6.7 and 4.2 kJ/m(3), respectively. T(built-in) values for Fe(81.6)Ga(13.8)Al(4.6) and Fe81.6Ga9.2Al9.2 alloys were 37 and 24 MPa, respectively. Estimated d(33) and mu(r) values ranged from 2.0 to 2.7 x 10(-8) m/A and 120-170 for all compositions studied. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3177325]

ID HYDRODYNAMIC PERFORMANCE; WHALE; SURFACES; MAMMALS
AB Cetaceans (whales, dolphins and porpoises) have evolved flippers that aid in effective locomotion through their aquatic environments. Differing evolutionary pressures upon cetaceans, including hunting and feeding requirements, and other factors such as animal mass and size have resulted in flippers that are unique among each species. Cetacean flippers may be viewed as being analogous to modern engineered hydrofoils, which have hydrodynamic properties such as lift coefficient, drag coefficient and associated efficiency. Field observations and the collection of biological samples have resulted in flipper geometry being known for most cetacean species. However, the hydrodynamic properties of cetacean flippers have not been rigorously examined and thus their performance properties are unknown. By conducting water tunnel testing using scale models of cetacean flippers derived via computed tomography (CT) scans, as well as computational fluid dynamic (CFD) simulations, we present a baseline work to describe the hydrodynamic properties of several cetacean flippers. We found that flippers of similar planform shape had similar hydrodynamic performance properties. Furthermore, one group of flippers of planform shape similar to modern swept wings was found to have lift coefficients that increased with angle of attack nonlinearly, which was caused by the onset of vortex-dominated lift. Drag coefficient versus angle of attack curves were found to be less dependent on planform shape. Our work represents a step towards the understanding of the association between performance, ecology, morphology and fluid mechanics based on the three-dimensional geometry of cetacean flippers.

AB Solar coronal mass ejections and their interplanetary counterparts often show evidence of a twisted flux rope structure that is nearly identical, though of vastly different spatial scale, to plasmoids observed in the Earth's magnetotail. This paper reviews the current understanding of flux rope formation, morphology, and evolution in coronal mass ejections and magnetotail plasmoids. It highlights the idea that flux rope formation is a common space physics phenomenon and that the physical mechanisms responsible for flux rope formation occur over a wide range of plasma conditions wherever current sheets exist.

AB An isotropic three-dimensional negative refractive index metamaterial has been fabricated and characterized in the visible regime. The metamaterial is based on a structure consisting of polycrystalline magnesium diboride (MgB2) as the host, providing negative permittivity, and silicon carbide (SiC) nanoparticles embedded randomly within the host, providing negative permeability. The metamaterial was fabricated using hot isostatic pressing to produce a fully dense solid with well-dispersed SiC nanoparticles. The properties of the resulting bulk metamaterial were evaluated using surface plasmon excitation, which showed coupling of both magnetic and electric plasmons, signifying both negative permeability and permittivity at 632 nm.

AB We report the discovery by the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope of high-energy. gamma-ray emission from the peculiar quasar PMN J0948+0022 (z = 0.5846). The optical spectrum of this object exhibits rather narrow H beta (FWHM(H beta) similar to 1500 km s(-1)), weak forbidden lines, and is therefore classified as a narrow-line type I quasar. This class of objects is thought to have relatively small black hole mass and to accrete at a high Eddington ratio. The radio loudness and variability of the compact radio core indicate the presence of a relativistic jet. Quasi-simultaneous radio/optical/X-ray and gamma-ray observations are presented. Both radio and gamma-ray emissions (observed over five months) are strongly variable. The simultaneous optical and X-ray data from Swift show a blue continuum attributed to the accretion disk and a hard X-ray spectrum attributed to the jet. The resulting broadband spectral energy distribution (SED) and, in particular, the gamma-ray spectrum measured by Fermi are similar to those of more powerful Flat-Spectrum Radio Quasars (FSRQs). A comparison of the radio and gamma-ray characteristics of PMN J0948+0022 with the other blazars detected by LAT shows that this source has a relatively low radio and gamma-ray power with respect to other FSRQs. The physical parameters obtained from modeling the SED also fall at the low power end of the FSRQ parameter region discussed in Celotti & Ghisellini. We suggest that the similarity of the SED of PMN J0948+0022 to that of more massive and more powerful quasars can be understood in a scenario in which the SED properties depend on the Eddington ratio rather than on the absolute power.

AB We report the discovery of gamma-ray pulsations from the nearby isolated millisecond pulsar (MSP) PSR J0030+0451 with the Large Area Telescope on the Fermi Gamma-ray Space Telescope (formerly GLAST). This discovery makes PSR J0030+0451 the second MSP to be detected in gamma rays after PSR J0218+4232, observed by the EGRET instrument on the Compton Gamma-Ray Observatory. The spin-down power (E) over dot = 3.5 x 10(33) erg s(-1) is an order of magnitude lower than the empirical lower bound of previously known gamma-ray pulsars. The emission profile is characterized by two narrow peaks, 0.07 +/- 0.01 and 0.08 +/- 0.02 wide, respectively, separated by 0.44 +/- 0.02 in phase. The first gamma-ray peak falls 0.15 +/- 0.01 after the main radio peak. The pulse shape is similar to that of the "normal" gamma-ray pulsars. An exponentially cutoff power-law fit of the emission spectrum leads to an integral photon flux above 100 MeV of (6.76 +/- 1.05 +/- 1.35) x 10(-8) cm(-2) s(-1) with cutoff energy (1.7 +/- 0.4 +/- 0.5) GeV. Based on its parallax distance of (300 +/- 90) pc, we obtain a gamma-ray efficiency L-gamma/E similar or equal to 15% for the conversion of spin-down energy rate into gamma-ray radiation, assuming isotropic emission.

AB We report on the Suzaku observation of neutron star (NS) low-mass X-ray binary Cygnus X-2 which reveals a presence of the iron K-alpha emission line. The line profile shows a significant red wing. This discovery increases the number of NS sources where red-skewed iron lines were observed and strongly suggests that this phenomenon is common not only in black holes but also in other types of accreting compact objects. We examine the line profile in terms of models which attribute its production to the relativistic effects due to reflection of X-ray radiation from a cold accretion disk and also as a result of the line formation in the extended wind/outflow configuration. Both models are able to adequately represent the observed line profile. We consider the results of line modeling in the context of subsecond variability. While we were unable to conclusively disqualify one of the models, we find that the wind paradigm has several advantages over the relativistic disk reflection model.

AB We present a spectral analysis of the Far Ultraviolet Spectroscopic Explorer (FUSE) spectra of the eclipsing double-line spectroscopic binary EM Cygni (EM Cyg), a Z Cam DN system. The FUSE spectrum, obtained in quiescence, consists of four individual exposures (orbits): two exposures, at orbital phases phi similar to 0.65 and phi similar to 0.90, have a lower flux; and two exposures, at orbital phases phi = 0.15 and 0.45, have a relatively higher flux. The change of flux level as a function of the orbital phase is consistent with the stream material (flowing over and below the disk from the hot spot region to smaller radii) partially masking the white dwarf. We carry out a spectral analysis of the FUSE data, obtained at phase 0.45 (when the flux is maximal), using synthetic spectra generated with the codes TLUSTY and SYNSPEC. Using a single white dwarf spectral component, we obtain a white dwarf temperature of 40,000 K +/- 1000 K, rotating at 100 km s(-1). The white dwarf, or conceivably, the material overflowing the disk rim, shows suprasolar abundances of silicon, sulphur, and possibly nitrogen. Using a white dwarf+disk composite model, we obtain that the white dwarf temperature could be even as high as 50,000 K, contributing more than 90% of the FUV flux, and the disk contributing less than 10% must have a mass accretion rate reaching 10(-10) M(circle dot) yr(-1). The single white dwarf model fits the absorption lines better than the white dwarf+disk model, but the white dwarf+disk model fits better the continuum in the shorter wavelengths. In both cases, however, we obtain that the white dwarf temperature is much higher than previously estimated. We emphasize the importance of modeling the spectra of EM Cyg around phase phi < 0.5, when the white dwarf and disk are facing the observer, and we suggest that the discrepancy between the present analysis and previous spectral analysis might be due to the occulting effect of the stream veiling the white dwarf and disk.

AB In a recent paper, we reported on the discovery of a radio halo with very steep spectrum in the merging galaxy cluster A521 through observations with the Giant Metrewave Radio Telescope. We showed that the steep spectrum of the halo is inconsistent with a secondary origin of the relativistic electrons and supports a turbulent acceleration scenario. At that time, due to the steep spectrum, the available observations at 1.4 GHz (archival NRAO-Very Large Array-VLA-CnB-configuration data) were not adequate to accurately determine the flux density associated with the radio halo. In this paper, we report the detection at 1.4 GHz of the radio halo in A521 using deep VLA observations in the D configuration. We use these new data to confirm the steep spectrum of the object. We consider A521 the prototype of a population of very steep spectrum halos. This population is predicted assuming that turbulence plays an important role in the acceleration of relativistic particles in galaxy clusters, and we expect it will be unveiled by future surveys at low frequencies with the LOFAR and LWA radio telescopes.

AB We have completed a survey for pulsars at high Galactic latitudes with the 64 m Parkes radio telescope. Observing with the 13 beam multibeam receiver at a frequency of 1374 MHz, we covered similar to 4150 square degrees in the region -100 degrees <= l <= 50 degrees, 15 degrees, <= vertical bar b vertical bar <= 30 degrees with 7232 pointings of 265 s each, thus extending the Swinburne Intermediate Latitude Pulsar Survey a further 15 degrees on either side of the Galactic plane. The signal from each beam was processed by a 96 channel x 3 MHz x 2 polarization filterbank, with the detected power in the two polarizations of each frequency channel summed and digitized with 1 bit sampling every 125 mu s, giving good sensitivity to millisecond pulsars with low or moderate dispersion measure. The resulting 2.4 TB data set was processed using standard pulsar search techniques with the workstation cluster at the Swinburne Centre for Astrophysics and Supercomputing. This survey resulted in the discovery of 26 new pulsars including seven binary and/or millisecond pulsars, and redetected 36 previously known pulsars. We describe the survey methodology and results, and present timing solutions for the 19 newly discovered slow pulsars, as well as for nine slow pulsars discovered the Swinburne Intermediate Latitude Pulsar Survey that had no previous timing solutions. Even with a small sampling interval, 1374 MHz center frequency, and a large mid-latitude survey volume we failed to detect any very rapidly spinning pulsars. Evidently, such "submillisecond" pulsars are rare.

AB We report the discovery of gamma-ray pulsations (>= 0.1 GeV) from the young radio and X-ray pulsar PSR J0205 + 6449 located in the Galactic supernova remnant 3C 58. Data in the gamma-ray band were acquired by the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope (formerly GLAST), while the radio rotational ephemeris used to fold gamma-rays was obtained using both the Green Bank Telescope and the Lovell telescope at Jodrell Bank. The light curve consists of two peaks separated by 0.49 +/- 0.01 +/- 0.01 cycles which are aligned with the X-ray peaks. The first gamma-ray peak trails the radio pulse by 0.08 +/- 0.01 +/- 0.01, while its amplitude decreases with increasing energy as for the other gamma-ray pulsars. Spectral analysis of the pulsed gamma-ray emission suggests a simple power law of index -2.1 +/- 0.1 +/- 0.2 with an exponential cutoff at 3.0(-0.7)(+1.1) +/- 0.4 GeV. The first uncertainty is statistical and the second is systematic. The integral gamma-ray photon flux above 0.1 GeV is (13.7 +/- 1.4 +/- 3.0) x 10(-8) cm(-2) s(-1), which implies for a distance of 3.2 kpc and assuming a broad fan-like beam a luminosity of 8.3 x 10(34) erg s(-1) and an efficiency eta of 0.3%. Finally, we report a 95% upper limit on the flux of 1.7 x 10(-8) cm(-2) s(-1) for off-pulse emission from the object.

AB Since its identification in April 2009, an A(H1N1) virus containing a unique combination of gene segments from both North American and Eurasian swine lineages has continued to circulate in humans. The lack of similarity between the 2009 A(H1N1) virus and its nearest relatives indicates that its gene segments have been circulating undetected for an extended period. Its low genetic diversity suggests that the introduction into humans was a single event or multiple events of similar viruses. Molecular markers predictive of adaptation to humans are not currently present in 2009 A(H1N1) viruses, suggesting that previously unrecognized molecular determinants could be responsible for the transmission among humans. Antigenically the viruses are homogeneous and similar to North American swine A(H1N1) viruses but distinct from seasonal human A(H1N1).

AB The recent discovery of a circuit of brain regions that is highly active in the absence of overt behavior has led to a quest for revealing the possible function of this so-called default-mode network (DMN). A very recent study, finding similarities in awake humans and anesthetized primates, has suggested that DMN activity might not simply reflect ongoing conscious mentation but rather a more general form of network dynamics typical of complex systems. Here, by performing functional MRI in humans, it is shown that a natural, sleep-induced reduction of consciousness is reflected in altered correlation between DMN network components, most notably a reduced involvement of frontal cortex. This suggests that DMN may play an important role in the sustenance of conscious awareness.

TI Effect of large strain on dielectric and ferroelectric properties of
Ba0.5Sr0.5TiO3 thin films
SO APPLIED PHYSICS LETTERS

DT Article
ID MICROWAVE PROPERTIES; STRESS
AB BaxSr1-xTiO3 is ideally suited as a tunable medium for radio frequency passive component. In this context we have studied the effect of biaxial strain on the dielectric and ferroelectric properties of Ba0.5Sr0.5TiO3 thin films grown epitaxially on SrTiO3 (001) substrates. The lattice parameters of the films determined by high-resolution x-ray diffraction with the thickness varying from 160 to 1000 nm indicated large biaxial compressive strain which decreased from 2.54% to 1.14% with increasing film thickness. Temperature-dependent measurements of the dielectric constant in our strained Ba0.5Sr0.5TiO3 thin films revealed a significant increase in the Curie temperature as the film thickness is below 500 nm. Enhanced ferroelectric behavior was observed for highly strained films with a remanent polarization of 15 mu C/cm(2) in the 160-nm-thick layer. However, the thick films (>= 500 nm) exhibited weak temperature dependence of the dielectric constant without any pronounced peak corresponding to the Curie temperature, which may suggest inhomogeneous strain distribution in the thick films.

TI Ultra-low temperature sensitive deep-well quantum cascade lasers
(lambda=4.8 mu m) via uptapering conduction band edge of injector
regions
SO ELECTRONICS LETTERS
LA English
DT Article
AB A new design feature for deep-well quantum cascade (QC) lasers, in which the conduction band edge of the injector region is uptapered, results in virtual suppression of carrier leakage out of the active regions of 4.8 mu m emitting devices. For heatsink temperatures in the 20-90 degrees C range the characteristic temperature coefficients for threshold, T(0), and slope efficiency, T(1), reach values as high as 278 and 285 K, respectively, which are nearly twice the values for conventional QC lasers. At 20 degrees C, the threshold current density for uncoated, 30 period, 3 mm-long devices is only similar to 1.8 kA/cm(2).

AB Robust Si resonant interband tunnel diodes have been designed and tested that demonstrate as-grown negative differential resistance at room temperature with peak-to-valley current ratios (PVCR) up to 2.5 and peak current densities in the order of 1 kA/cm(2). The as-grown Si p(+) in(+) structures were synthesised using solid source molecular beam epitaxy, incorporating B and P delta-doped layers. Both structures have shown thermal stability after 1 min post-growth anneals up through 675 degrees C and the PVCR improves to 2.8 for a 575 degrees C 1 min anneal.

AB OBJECTIVE. Liver stiffness is associated with portal hypertension in patients with chronic liver disease. However, the relation between spleen stiffness and clinically significant portal hypertension remains unknown. The purposes of this study were to determine the feasibility of measuring spleen stiffness with MR elastography and to prospectively test the technique in healthy volunteers and in patients with compensated liver disease.
MATERIALS AND METHODS. Spleen stiffness was measured with MR elastography in 12 healthy volunteers ( mean age, 37 years; range, 25-82 years) and 38 patients ( mean age, 56 years; range, 36-60 years) with chronic liver disease of various causes. For patients with liver disease, laboratory findings, spleen size, presence and size of esophageal varices, and liver histologic results were recorded. Statistical analyses were performed to assess all measurements.
RESULTS. MR elastography of the spleen was successfully performed on all volunteers and patients. The mean spleen stiffness was significantly lower in the volunteers (mean, 3.6 +/- 0.3 kPa) than in the patients with liver fibrosis (mean, 5.6 +/- 5.0 kPa; range, 2.7-9.2 kPa; p < 0.001). In addition, a significant correlation was observed between liver stiffness and spleen stiffness for the entire cohort (r(2) = 0.75; p < 0.001). Predictors of spleen stiffness were splenomegaly, spleen volume, and platelet count. A mean spleen stiffness of 10.5 kPa or greater was identified in all patients with esophageal varices.
CONCLUSION. MR elastography of the spleen is feasible and shows promise as a quantitative method for predicting the presence of esophageal varices in patients with advanced hepatic fibrosis.

TI Orthopaedic Injuries Associated With Skimboarding
SO AMERICAN JOURNAL OF SPORTS MEDICINE
LA English
DT Article
DE skimboarding; fracture; injury pattern; injury prevention
ID SURFING INJURIES
AB Background: Skimboarding is a beachside water sport that is enjoying increasing popularity among both dedicated enthusiasts and casual beachgoers. Although many consider this sport to be similar to its "sister" sport, surfing, the technique, the environment in which it is performed, and the skills required differ dramatically from that of surfing. Moreover, the pattern of injuries seen in skimboarders differs substantially from those sustained while surfing.
Hypothesis: A better understanding of the injuries encountered in this sport will allow improved participant education and facilitate the implementation of preventative measures.
Study Design: Descriptive epidemiology study.
Methods: A case series was generated by performing a single retrospective chart review of skimboarding injuries referred for orthopaedic evaluation over a 2-year period at 2 medical treatment facilities, one on the East Coast and one on the West Coast of the United States; demographic data, injury type, and treatments rendered were documented.
Results: Sixty-one patients were identified and analyzed. Average patient age was 19.1 years. Fractures represented 93.4% of all acute injuries. The most common sites of injury were the ankle (41%) and wrist (36%). Rotation about a planted lower extremity was the most common mechanism of injury (30/61, 49%), followed by falls onto an outstretched hand (26/61, 43%).
Conclusion: Fractures of the ankle and wrist comprise a high proportion of skimboarding injuries. Knowledge of potential hazards associated with this sport should be made available to participants. To decrease the risk of orthopaedic injury, the use of protective equipment or instruction in proper techniques of the activity may be warranted.

AB We conducted a longitudinal observational study of 533 patients presenting to two hospitals in the Ecuadorean Amazon basin with acute undifferentiated febrile illness (AUFI) from 2001 through 2004. Viral isolation, reverse transcription-polymerase chain reaction (RT-PCR), IgM seroconversion, and malaria smears identified pathogens responsible for fever in 122 (40.1%) of 304 patients who provided both acute and convalescent blood samples. Leptospirosis was found in 40 (13.2%), malaria in 38 (12.5%), rickettsioses in 18 (5.9%), dengue fever in 16 (5.3%), Q fever in 1.5 (4.9%), brucellosis in 4 (1.3%), Ilheus infection in 3 (1.0%), and Venezuelan equine encephalitis (VEE), Oropouche, and St. Louis encephalitis virus infections in less than 1% of these patients. Viral isolation and RT-PCR on another 229 participants who provided only acute samples identified 3 cases of dengue fever, 2 of VEE, and 1 of Ilheus. None of these pathogens, except for malaria, had previously been detected in the study area.

DT Article
ID FLOW CYTOMETER; ARRAY IMMUNOSENSOR; SYSTEM
AB A microfabricated flow cytometer was used to demonstrate multiplexed detection of bacteria and toxins using fluorescent coded microspheres. Antibody-coated microspheres bound biothreat targets in a sandwich immunoassay format. The microfluidic cytometer focused the microspheres in three dimensions within the laser interrogation region using passive groove structures to surround the sample stream with sheath fluid. Optical analysis at four different wavelengths identified the coded microspheres and quantified target bound by the presence of phycoerythrin tracer. The multiplexed assays in the microflow cytometer had performance approaching that of a commercial benchtop flow cytometer. The respective limits of detection for bacteria (Escherichia coli, Listeria, and Salmonella) were found to be 10(3), 10(5), and 10(4) cfu/mL for the microflow cytometer and 10(3), 10(6), and 10(5) cfu/mL for the commercial system. limits of detection for the toxins (cholera toxin, staphylococcal enterotoxin B, and ricin) were 1.6, 0.064, and 1.6 ng/mL for the microflow cytometer and 1.6, 0.064, and 8.0 ng/mL for the commercial system.

AB Four active duty military personnel and two retired soldiers/military contractors were treated with spinal or peripheral nerve stimulators. All six personnel were able to deploy after the stimulators were placed. Five patients had no incidents during their deployments. One patient completed four deployments but had mechanical complications that necessitated eventual revisions.
Considering the risks and limitations of reoperation, nerve blocks, and pharmacotherapy in a forward-deployed area, spinal cord stimulation provides an appealing alternative in soldiers who desire to remain deployable on active duty. (Anesth Analg 2009:109:245-8)

PROSTATE-CANCER; COLON-CANCER; COLORECTAL-CANCER; D SUPPLEMENTATION
AB PURPOSE: Higher serum levels of the main circulating form of vitamin D, 25-hydroxyvitamin D (25(OH)D), are associated with substantially lower incidence rates of colon, breast, ovarian, renal, pancreatic, aggressive prostate and other cancers.
METHODS: Epidemiological findings combined with newly discovered mechanisms suggest a new model of cancer etiology that accounts for these actions of 25(OH)D and calcium. Its seven phases are disjunction, initiation, natural selection, overgrowth, metastasis, involution, and transition (abbreviated DINOMIT). Vitamin D metabolites prevent disjunction of cells and are beneficial in other phases.
RESULTS/CONCLUSIONS: It is projected that raising the minimum year-around serum 25(OH)D level to 40 to 60 ng/mL (100-150 nmol/L) would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three fourths of deaths from these diseases in the United States and Canada, based on observational studies combined with a randomized trial. Such intakes also are expected to reduce case-fatality rates of patients who have breast, colorectal, or prostate cancer by half. There are no unreasonable risks from intake of 2000 IU per day of vitamin D(3), or from a population serum 25(OH)D level of 40 to 60 ng/mL. The time has arrived for nationally coordinated action to substantially increase intake of vitamin D and calcium. Ann Epidemiol 2009; 19:468-483. (C) Published by Elsevier Inc.

ID SCATTERING; WATERS; DESIGN
AB We report experimental results from a flow-through integrating cavity absorption meter. The operating range of the device is from 0.004 m(-1) to over 80 m(-1) of absorption. Absorption coefficients have been measured with 8% or less change in the presence of over 200 m(-1) of scattering in the medium. The instrument signal has been shown to be independent of flow rate up to 20 liters/min and thus independent of turbulence. This large operational range along with the ability to measure absorption independently of adverse scattering affects allows the instrument to be utilized in a wide range of environmental conditions.

TI An Evaluation of the Effectiveness of Different Techniques for
Intraoperative Infiltration of Antibiotics Into Alloplastic Implants for
Use in Facial Reconstruction
SO ARCHIVES OF FACIAL PLASTIC SURGERY
LA English
DT Article
ID BONE-CEMENT; POLYETHYLENE IMPLANTS; PROPHYLAXIS; INFECTION
AB Background: Reconstruction in the head and neck can be difficult owing to the size of the defect or characteristics of the tissue that needs to be replaced. Facial wounds or reconstruction sites can be subject to contamination, thereby risking infection of any implanted material even under ideal circumstances. Particular areas of concern are sites where minimizing the bacterial contamination prior to placing an implant is difficult (eg, the oral cavity and internal nose). Reconstruction involves the facial subcutaneous soft tissue and/or bone, and the ideal implant provides support and natural feel, as well as a low risk of infection. The biocompatibility of alloplastic implants depends on the tissue inertness of the implant and the porosity, allowing connective tissue ingrowth, which in turn decreases the susceptibility to infection. Scalafani et al demonstrated that alloplastic implants contaminated prior to fibrovascular ingrowth had a much higher incidence of infection and rejection.
Objective: To examine the effectiveness of several techniques for infiltrating antibiotics into alloplastic implants of different porosity using 2 commonly used alloplastic implants, expanded polytetrafluoroethylene (e-PTFE, or GORE-TEX) and porous high-density polyethylene (Medpor).
Results: Using an in vitro bacterial growth inhibition model, we found that suction infiltration of the implant with antibiotics was the most effective technique, with a statistically significant advantage over other techniques used. The advantages of the suction impregnation were seen to be most effective using alloplasts with a smaller pore size (20-30 mu m) (P < .001), but there was a statistically significant difference even with implants with a larger pore size (150-200 mu m) (P <. 001).
Conclusions: Suction infiltration of antibiotics into porous implants seems to be the most effective method identified using an in vitro testing protocol. Further experiments will be needed to confirm the effectiveness in reducing the perioperative risk of infection in vivo.

AB The use of implants to provide glenohumeral soft tissue fixation has changed dramatically over the past few decades, from point tack fixation to metallic suture anchors to bioabsorbable suture anchors. Bioabsorbable suture anchors have largely replaced metallic anchors because of concerns of implant loosening, migration, and chondral injury. Although the safety and efficacy of bioabsorbable anchors has been well documented, there are numerous reports regarding the early failure related to implant bioabsorbable implant breakage or premature degradation. Patients with anchor-related complications generally present with pain and/or stiffness, and the surgeon should have a high index of suspicion if a patient does not progress as expected. Glenohumeral synovitis, glenoid osteolysis, loose bodies, and chondral injury are some of the notable complications that have been reported. Careful attention to proper anchor insertion techniques can limit the potential for complications. Newer materials, such as polyetheretherketone and other composites, have recently been introduced. These materials may address concerns of biocompatibility and material strength, but additional rigorous in vitro and in vivo trials need to be conducted before their use becomes widespread.

AB Active galactic nuclei (AGN) at the center of galaxy clusters with gas cooling times that are much shorter than the Hubble time have emerged as heating agents powerful enough to prevent further cooling of the intracluster medium (ICM). We carried out an intensive study of the AGN heating-ICM cooling network by comparing various cluster parameters to the integrated radio luminosity of the central AGN, L(R), defined as the total synchrotron power between 10 MHz and 15 GHz. This study is based on the HIFLUGCS sample comprising the 64 X-ray brightest galaxy clusters. We adopted the central cooling time, t(cool), as the diagnostic to ascertain cooling properties of the HIFLUGCS sample and classify clusters with t(cool) < 1 Gyr as strong cool-core (SCC) clusters, with 1 Gyr < t(cool) < 7.7 Gyr as weak cool-core (WCC) clusters and with t(cool) > 7.7 Gyr as non-cool-core (NCC) clusters. We find 48 out of 64 clusters (75%) contain cluster center radio sources (CCRS) cospatial with or within 50 h(71)(-1) kpc of the X-ray peak emission. Furthermore, we find that the probability of finding a CCRS increases from 45% to 67% to 100% for NCC, WCC, and SCC clusters, respectively.
We use a total of similar to 140 independent radio flux-density measurements, with data at more than two frequencies for more than 54% of the sources extending below 500 MHz, enabling the determination of accurate estimates of L(R). We find that L(R) in SCC clusters depends strongly on the cluster scale such that more massive clusters harbor more powerful radio AGN. The same trend is observed between L(R) and the classical mass deposition rate,. M(classical) in SCC and partly also in WCC clusters, and can be quantified as L(R) proportional to M(classical)(1.69 +/- 0.25). We also perform correlations of the luminosity for the brightest cluster galaxy, L(BCG), close to the X-ray peak in all 64 clusters with L(R) and cluster parameters, such as the virial mass, M(500), and the bolometric X-ray luminosity, L(X). To this end, we use the 2MASS K-band magnitudes and invoke the near-infrared bulge luminosity-black hole mass relation to convert L(BCG) to supermassive black hole mass, M(BH). We find a weak correlation between M(BH) and L(R) for SCC clusters, L(R) similar to M(BH)(4.10 +/- 0.42), although with a few outliers. We find an excellent correlation of L(BCG) with M(500) and L(X) for the entire sample, the SCC clusters showing a tighter trend in both the cases. We discuss the plausible reasons behind these scaling relations in the context of cooling flows and AGN feedback.
Our results strongly suggest an AGN-feedback machinery in SCC clusters, which regulates the cooling in the central regions. Since the dispersion in these correlations, such as that between L(R) and M(classical) or L(R) and M(BH), increases in going from SCC to WCC clusters, we conclude there must be secondary processes that work either in conjunction with the AGN heating or independently to counteract the radiative losses in WCC clusters.

AB Calibration of radio interferometric observations becomes increasingly difficult towards lower frequencies. Below similar to 300 MHz, spatially variant refractions and propagation delays of radio waves traveling through the ionosphere cause phase rotations that can vary significantly with time, viewing direction and antenna location. In this article we present a description and first results of SPAM (Source Peeling and Atmospheric Modeling), a new calibration method that attempts to iteratively solve and correct for ionospheric phase errors. To model the ionosphere, we construct a time-variant, 2-dimensional phase screen at fixed height above the Earth's surface. Spatial variations are described by a truncated set of discrete Karhunen-Loeve base functions, optimized for an assumed power-law spectral density of free electrons density fluctuations, and a given configuration of calibrator sources and antenna locations. The model is constrained using antenna-based gain phases from individual self-calibrations on the available bright sources in the field-of-view. Application of SPAM on three test cases, a simulated visibility data set and two selected 74 MHz VLA data sets, yields significant improvements in image background noise (5-75 percent reduction) and source peak fluxes (up to 25 percent increase) as compared to the existing self-calibration and field-based calibration methods, which indicates a significant improvement in ionospheric phase calibration accuracy.

AB We report the discovery of high-energy (E > 100 MeV) gamma-ray emission from NGC 1275, a giant elliptical galaxy lying at the center of the Perseus cluster of galaxies, based on observations made with the Large Area Telescope (LAT) of the Fermi Gamma-ray Space Telescope. The positional center of the gamma-ray source is only approximate to 3' away from the NGC 1275 nucleus, well within the 95% LAT error circle of approximate to 5'. The spatial distribution of gamma-ay photons is consistent with a point source. The average flux and power-law photon index measured with the LAT from 2008 August 4 to 2008 December 5 are F-gamma = (2.10 +/- 0.23) x 10(-7) ph (>100 MeV) cm(-2) s(-1) and Gamma = 2.17 +/- 0.05, respectively. The measurements are statistically consistent with constant flux during the four-month LAT observing period. Previous EGRET observations gave an upper limit of F-gamma < 3.72 x 10(-8) ph (>100 MeV) cm(-2) s(-1) to the gamma-ray flux from NGC 1275. This indicates that the source is variable on timescales of years to decades, and therefore restricts the fraction of emission that can be produced in extended regions of the galaxy cluster. Contemporaneous and historical radio observations are also reported. The broadband spectrum of NGC 1275 is modeled with a simple one-zone synchrotron/synchrotron self-Compton model and a model with a decelerating jet flow.

AB Two well known phenomena associated with erupting filaments are the transient coronal holes that form on each side of the filament channel and the bright post-event arcade with its expanding double row of footpoints. Here we focus on a frequently overlooked signature of filament eruptions: the spike- or fan-shaped brightenings that appear to mark the far endpoints of the filament. From a sample of non-active-region filament events observed with the Extreme-Ultraviolet Imaging Telescope on the Solar and Heliospheric Observatory, we find that these brightenings usually occur near the outer edges of the transient holes, in contrast to the post-event arcades, which define their inner edges. The endpoints are often multiple and are rooted in and around strong network flux well outside the filament channel, a result that is consistent with the axial field of the filament being much stronger than the photospheric field inside the channel. The extreme ultraviolet brightenings, which are most intense at the time of maximum outward acceleration of the filament, can be used to determine unambiguously the direction of the axial field component from longitudinal magnetograms. Their location near the outer boundary of the transient holes suggests that we are observing the footprints of the current sheet formed at the leading edge of the erupting filament, as distinct from the vertical current sheet behind the filament which is the source of the post-event arcade.

AB We present a study of correlations between X-ray spectral and timing properties observed from a number of Galactic black hole (BH) binaries during hard-soft state spectral evolution. We analyze 17 transition episodes from eight BH sources observed with Rossi X-Ray Timing Explorer. Our scaling technique for BH mass determination uses a correlation between the spectral index and quasi-periodic oscillation (QPO) frequency. In addition, we use a correlation between the index and the normalization of the disk "seed" component to cross-check the BH mass determination and estimate the distance to the source. While the index-QPO correlations for two given sources contain information on the ratio of the BH masses in those sources, the index-normalization correlations depend on the ratio of the BH masses and the distance square ratio. In fact, the index-normalization correlation also discloses the index-mass accretion rate saturation effect given that the normalization of disk "seed" photon supply is proportional to the disk mass accretion rate. We present arguments that this observationally established index saturation effect is a signature of the bulk motion (converging) flow onto a BH, which was early predicted by the dynamical Comptonization theory. We use GRO J1655-40 as a primary reference source for which the BH mass, distance, and inclination angle are evaluated by dynamical measurements with unprecedented precision among other Galactic BH sources. We apply our scaling technique to determine BH masses and distances for Cygnus X-1, GX 339-4, 4U 1543-47, XTE J1550-564, XTE J1650-500, H 1743-322, and XTE J1859-226. A good agreement of our results for sources with known values of BH masses and distance provides independent verification for our scaling technique.

AB This is the first report of Fermi Gamma-Ray Space Telescope observations of the quasar 3C 454.3, which has been undergoing pronounced long-term outbursts since 2000. The data from the Large Area Telescope, covering 2008 July 7-October 6, indicate strong, highly variable.-ray emission with an average flux of similar to 3 x 10 (6) photons cm(-2) s(-1), for energies > 100 MeV. The gamma-ray flux is variable, with strong, distinct, symmetrically shaped flares for which the flux increases by a factor of several on a timescale of about 3 days. This variability indicates a compact emission region, and the requirement that the source is optically thin to pair production implies relativistic beaming with Doppler factor delta > 8, consistent with the values inferred from Very Long Baseline Interferometry observations of superluminal expansion (delta similar to 25). The observed gamma-ray spectrum is not consistent with a simple power law, but instead steepens strongly above similar to 2 GeV, and is well described by a broken power law with photon indices of similar to 2.3 and similar to 3.5 below and above the break, respectively. This is the first direct observation of a break in the spectrum of a high-luminosity blazar above 100 MeV, and it is likely direct evidence for an intrinsic break in the energy distribution of the radiating particles. Alternatively, the spectral softening above 2 GeV could be due to gamma-ray absorption via photon-photon pair production on the soft X-ray photon field of the host active galactic nucleus, but such an interpretation would require the dissipation region to be located very close (less than or similar to 100 gravitational radii) to the black hole, which would be inconsistent with the X-ray spectrum of the source.
