AB Multispectral imaging (MSI) data collected at multiple angles over shallow water provide analysts with a unique perspective of bathymetry in coastal areas. Observations taken by DigitalGlobe's WorldView-2 (WV-2) sensor acquired at 39 different view angles on 30 July 2011 were used to determine the effect of acquisition angle on bathymetry derivation. The site used for this study was Kailua Bay (on the windward side of the island of Oahu). Satellite azimuth and elevation for these data ranged from 18.8 to 185.8 degrees and 24.9 (forward-looking) to 24.5 (backward-looking) degrees (respectively) with 90 degrees representing a nadir view. Bathymetry were derived directly from the WV-2 radiance data using a band ratio approach. Comparison of results to LiDAR-derived bathymetry showed that varying view angle impact the quality of the inferred bathymetry. Derived and reference bathymetly have a higher correlation as images are acquired closer to nadir. The band combination utilized for depth derivation also has an effect on derived bathymetry. Four band combinations were compared, and the Blue & Green combination provided the best results.

DE WorldView-2; specular reflection; sun glint; ocean color
AB The Naval Research Laboratory (NRL) has been developing the Coastal Water Spectral Toolkit (CWST) to estimate water depth, bottom type and water column constituents such as chlorophyll, suspended sediments and chromophoric dissolved organic matter from hyperspectral imagery. The CWST uses a look-up table approach, comparing remote sensing reflectance spectra observed in an image to a database of modeled spectra for pre-determined water column constituents, depth and bottom type. Recently the CWST was modified to process multi-spectral World View-2 imagery. Generally imagery processed through the CWST has been collected under optimal sun and viewing conditions so as to minimize surface effects such as specular reflection. As such, in our standard atmospheric correction process we do not include a specular reflection correction. In June 2010 a series of 7 World View-2 images was collected within 2 minutes over Moreton Bay, Australia. The images clearly contain varying amounts of surface specular reflection. Each of the 7 images was processed through the CWST using identical processing to evaluate the impact of ignoring specular reflection on coverage and consistency of bottom types retrieved.

DE Constrained energy minimization (CEM); Causal CEM (C-CEM); Progressive
CEM (P-CEM); Real time CEM (RT-CEM)
ID HYPERSPECTRAL IMAGERY; N-FINDR; CLASSIFICATION; ALGORITHM
AB Constrained energy minimization (CEM) has been widely used for subpixel detection. It makes use of the sample correlation matrix R by suppressing the background thus enhancing detection of targets of interest. In many real world problems, implementing target detection on a timely basis is crucial, specifically moving targets. However, since the calculation of the sample correlation matrix R needs the complete data set prior to its use in detection, CEM is prevented from being implemented as a real time processing algorithm. In order to resolve this dilemma, the sample correlation matrix R must be replaced with a causal sample correlation matrix formed by only those data samples that have been visited and the currently being processed data sample. This causality is a pre-requisite to real time processing. By virtue of such causality, designing and developing a real time processing version of CEM becomes feasible. This paper presents a progressive CEM (PCEM) where the causal sample correlation matrix can be updated sample by sample. Accordingly, PCEM allows the CEM to be implemented as a causal CEM (C-CEM) as well as real time (RT) CEM via a recursive update equation in real time.

AB We report a low-cost fabrication method that transforms silica paper into an array of nanopipes with conductive, nanoscopic carbon walls in which the inner and outer carbon surfaces and the inner and outer voids are interconnected in three dimensions. Ultrathin (10-800 nm) carbon coatings are controllably deposited at 1000 degrees C from hydrocarbon vapors onto the fibers of commercial silica filter paper to create a conductive C@SiO2 paper with a shell of carbon wrapping each silica fiber. The cylindrical silica fibril cores that comprise the paper can then be chemically etched to yield a self-supported assembly of hollow, open, thin-walled carbon pipes with continuous electronic pathways and large interfacial areas while retaining the form factor of the original silica paper. Many "lost-wax" templating approaches have been reported, but this protocol enables one to synthetically fine-tune the carbon wall thickness in similar to 10-nm increments such that the ratio of the inner diameter of the pipe to the wall thickness can be as large as 100:1. This two-step route to scalable arrays of carbon pipes ("ductwork") uses inexpensive and readily available precursors and generates a freestanding ultraporous object that can function as stand-alone electrode nanoarchitectures. Such macroscale form factors with nanoscopic conductive conduits are adaptable for advanced energy-storage devices or as an ultralight matrix for thermal management such as spot cooling.

AB This letter presents an experiment using a fully polarimetric hybrid-polarization (CL-pol) radar that employs separate spiral antennas for transmit of the orthogonal circular polarizations and operates from 8 to 16 GHz. We propose a model for the antenna cross-polarization isolation (XPI) and calibration of this radar. The transmit XPI is characterized by leveraging the Doppler shift caused by a continually rotating dihedral target illuminated by a circularly polarized wave. Experimental results show the validity of the radar model and antenna measurement technique.

AB Quantum dots (QDs) are well-established as photoluminescent nanoparticle probes for in vitro or in vivo imaging, sensing, and even drug delivery. A critical component of this research is the need to reliably conjugate peptides, proteins, oligonucleotides, and other biomolecules to QDs in a controlled manner. In this chapter, we describe the conjugation of peptides to CdSe/ZnS QDs using a combination of polyhistidine self-assembly and hydrazone ligation. The former is a high-affinity interaction with the inorganic surface of the QD; the latter is a highly efficient and chemoselective reaction that occurs between 4-formylbenzoyl (4FB) and 2-hydrazinonicotinoyl (HYNIC) moieties. Two methods are presented for modifying peptides with these functional groups: (1) solid phase peptide synthesis; and (2) solution phase modification of presynthesized, commercial peptides. We further describe the aniline-catalyzed ligation of 4FB- and HYNIC-modified peptides, in the presence of a fluorescent label on the latter peptide, as well as subsequent assembly of the ligated peptide to water-soluble QDs. Many technical elements of these protocols can be extended to labeling peptides with other small molecule reagents. Overall, the bioconjugate chemistry is robust, selective, and modular, thereby potentiating the controlled conjugation of QDs with a diverse array of biomolecules for various applications.

AB We describe the development of a magnetic logic device that is uniquely different from spintronic approaches based on magnetoresistive effects that derive from spin dependent transport of carriers. The core of our device is a thin film avalanche diode channel fabricated as a p-n bilayer. Because of the structural asymmetry, the carriers are sensitive to an in-plane magnetic field and the diode has a large magnetoresistance. We characterize our device as a current switch. The high- and low-current states are well defined and are determined by the magnetic field. Positive or negative field orientation with constant field strength is an appropriate selector. We then describe an integrated avalanche diode logic device in which the magnetic field is provided by the local fringe field from a patterned ferromagnetic film with nanometer dimensions. The magnetization orientation of the nanomagnet, and the sign of the magnetic field, is set by spin torque transfer (STT) using small amplitude current pulses. We describe how simple arrangements of these integrated devices can be used as dynamically reconfigurable logic gates. Reconfigurable Boolean AND/OR gates using early prototype structures with micron dimensions are shown. Scaling arguments that justify the plausibility of fabricating an integrated device with dimensions of 100 nm are presented. These arguments suggest that such a device could produce an output current driving STT write processes and provide fanout capability in an integrated network.

AB Pulsed-laser single-event effects experiments on a 65 nm bulk CMOS integrated circuit confirms the existence of single-event pulse quenching and supports previous heavy-ion results. Strikes on pMOS transistors adjacent to each other are most susceptible to pulse quenching, with the pulsed-laser results emphasizing the proclivity of common n-well designs to pulse quenching. Correlation of the laser data with heavy-ion data shows that pulse quenching can occur below an LET of 9 MeV-cm(2)/mg.

AB This paper demonstrates the functionality of a power electronics based energy management system (EMS). An EMS can optimize the use of energy sources and energy storage systems in microgrids. It can provide an intelligent interface with the main grid when the microgrid is connected, and it makes the microgrid fault tolerant by providing power to critical loads when the main power source fails. The EMS presented in this paper is developed on a digitally controlled power electronics system which can act as a current source or a voltage source depending on the situation. The EMS functionality is demonstrated by modeling, simulations and experimental measurements.

AB Presented here are data describing the phase behavior and solvation of lithium trifluoromethanesulfonate (LiCF3SO3) in propylene carbonate (PC). Data obtained from differential scanning calorimetry (DSC) and Raman spectroscopy of sample mixtures are correlated to enhance understanding of solvent-salt associations. A phase diagram will display the behavior of the solvent-salt interactions. The binary phase diagram constructed from thermal data acquired by DSC analyses indicated only glass transition temperatures for all mixtures of PC-LiCF3SO3 tested. Raman spectroscopy is applied to probe the liquid electrolyte and discover solvent-salt associations in solution. Results indicate that mixtures of PC-LiCF3SO3 do not readily form solvent-separated ion pairs but rather tend toward contact ion pair and more aggregated solvates. Overall, this study provided some insight into electrolyte solvation of these model battery electrolyte species.

AB Boron-doped diamond (BDD) electrodes prepared by chemical vapor deposition were used to determine if phenol could be oxidized to CO2 and if biofilms could be oxidized and "cleaned" from a surface. Cyclic voltammetry showed that phenol and biofilms were electrolyzed by the BDD electrodes and that the oxidation products did not foul the electrodes. Experiments were also run with a flow cell in which a liter of 10 mM phenol in 0.1M H2SO4 was circulated through the cell and the total organic carbon (TOC) was monitored as a function of time and cell current. The total carbon in solution was reduced from similar to 1% to <0.1% with no observable decrease in decomposition rate. This low, total organic carbon content supports that the reacted phenol was converted completely to CO2.

AB We have demonstrated efficient propagation of the first excited TE01, TM01, and HE21 modes in a nanofiber with a radius of 400 nm. As we decrease the taper angle from 4 mrad to 1 mrad, the propagation becomes more adiabatic and the transmission improves from 20% to 85%. We have also demonstrated that the choice of drawn fiber can have a significant impact on the propagation characteristics.

DE SWIR; MWIR; LWIR; MILTRAN; IR glass; multispectral optics
AB We report new multispectral materials that transmit from 0.9 to > 12 mu m in wavelength. These materials fill up the glass map for multispectral optics and vary in refractive index from 2.38 to 3.17. They show a large spread in dispersion (Abbe number) and offer some unique solutions for multispectral optics designs. One of the glasses developed is a very good candidate to replace Ge, as it has a combination of excellent properties, including high Abbe number in the LWIR, high index of 3.2, 60% lower dn/dT, and better thermal stability at working temperatures. Our results also provide a wider selection of optical materials to enable simpler achromat designs. For example, we have developed other glasses that have relatively high Abbe number in both the MWIR and LWIR regions, while our MILTRAN ceramic has low Abbe number in both regions. This makes for a very good combination of glasses and MILTRAN ceramic (analogous to crown and flint glasses in the visible) for MWIR + LWIR dual band imaging. We have designed preliminary optics for one such imager with f/2.5, 51 mm focal length and 22 degrees FOV using a spaced doublet of NRL's glass and MILTRAN ceramic. NRL's approach reduces the number of elements, weight, complexity and cost compared with the approach using traditional optics. Another important advantage of using NRL glasses in optics design is their negative or very low positive dn/dT, that makes it easier to athermalize the optical system.

The cables tested included chalcogenide fiber cables with endfaces imprinted with anti-reflective "moth eye" surfaces, whereby the reflection loss is reduced from about 17% per end to less than 3%. The cables with these moth eye surfaces also show excellent laser damage resistance.

AB In this research, fiber Bragg grating (FBG) temperature sensors are embedded in composites in order to detect highly localized temperature gradients in the composite structures. The primary goal is to perform structural health monitoring on a composite structure. A secondary goal is to use the sensors as a diagnostic tool to determine the optimal composite materials, architectures, or structures that are the least susceptible to thermal damage. Initial results will be discussed for two composite materials using a single sensor to measure temperature variations. The tests include measurements of the temporal and spatial thermal response of the composite resulting either from an applied heat source or to high energy radiation incident on the surface. Additional tests demonstrate the response using a 3x2 array of sensors to simultaneously measure the temperature at three varying depths in the composite, using three FBGs aligned with the heat source, and three FBGs located a short lateral distance (3cm) away from the heat source. In addition, since FBGs respond to strain as well as to temperature, any strain in the composite is coupled into the embedded fiber and is also detected by the FBG sensors. Initial measurements demonstrate the simultaneous response of FBG sensors to both temperature and strain. The various components of strain that are observed in the composite will be discussed, and possible methods to isolate these components and mitigate their response will be considered.

AB We report on the fabrication of a microelectromechanical systems (MEMS) based bi-material terahertz (THz) detector integrated with a metamaterial structure to provide high absorption at 3.8 THz. The absorbing element of the sensor was designed with a resonant frequency that matches the quantum cascade laser illumination source, while simultaneously providing structural support, desired thermomechanical properties and optical read-out access. It consists of a periodic array of aluminum squares separated from a homogeneous aluminum (Al) ground plane by a silicon-rich silicon oxide (SiOx) layer. The absorbing element is connected to two Al/SiOx microcantilevers (legs), anchored to a silicon substrate, which acts as a heat sink, allowing the sensor to return to its unperturbed position when excitation is terminated. The metamaterial structure absorbs the incident THz radiation and transfers the heat to the legs where the significant difference between thermal expansion coefficients of Al and SiOx causes the structure to deform proportionally to the absorbed power. The amount of deformation is probed optically by measuring the displacement of a laser beam reflected on the Al ground plane of the metamaterial absorber. Measurement showed that the fabricated absorber has nearly 95% absorption at 3.8 THz. The responsivity and time constant were found to be 1.2 deg/mu W and 0.3 s, respectively. The minimum detectable incident power including the readout noise is around 9 nW. The obtained high sensitivity and design flexibility indicate that sensor can be further tuned to achieve the required parameters for real time THz imaging applications.

AB We present the microfabrication and cold test measurement results of serpentine waveguide amplifier circuits at 220 GHz. The circuits were fabricated using a novel embedded polymer monofilament technique combined with Ultraviolet-LIGA to simultaneously create both the beam tunnel and interaction circuits. We find remarkable characteristic matches between the measurements of the best circuits, illustrating that the process developed is able to create repeatable, highly precise circuits with high yield. It was found that slight beam tunnel misalignment can cause very strong stopbands to appear in the operating band due to bi- or quasi-periodicity. The NRL code TESLA-SW/FW has been used to rapidly simulate the as-built structure under a variety of conditions to accurately predict the performance with an electron beam. The tolerances needed on beam tunnel alignment are studied, with implications extending to the THz range.

AB Continued progress in terahertz (THz) research has emphasized the need for both improved THz sources and detectors. One approach to generate a narrowband THz radiation is to use metamaterial absorbers as thermal emitters. We present metamaterial based THz emitters consisting of a 100 nm aluminum layer patterned into squares separated from a ground plane of aluminum by a thin layer of silicon oxide (<2 mu m) fabricated using standard microfabrication techniques. These metamaterials were designed to emit in one, two, and three different bands of the 4-8 THz range and demonstrate clearly definable separate peaks with bandwidths of approximately 1 THz. Modifying the multiple band configurations can produce relatively broad emission peak if desired. Single band emitters designed for 4.1, 5.4, and 7.8 THz were observed to emit, respectively, 11, 18, and 36 W/m(2) at 400 degrees C in accordance with Kirchhoff's law of thermal radiation. Coating a 4-inch wafer with these materials and heating it to 400 degrees C would produce an estimated 86, 145, and 280 mW of power, respectively. Additionally, emitted power increased linearly with temperature, as expected from the Planck's radiation law in the THz spectral region at elevated temperatures. Emissivity of the metamaterial did not change significantly when heated, indicating that the constituent materials did not significantly change their optical or geometric properties.

AB The U.S. Naval Research Laboratory (NRL) is developing a battery-powered, rep-rate charger for a 60-kJ capacitor bank. The capacitor will be charged with a bank of LiFePO4 batteries in conjunction with a DC-DC converter. During discharge, the batteries will generate heat from the internal resistance. If the heat is not addressed, damage to the cell may occur, leading to degraded cell lifetime and the potential for cell venting. NRL has developed an integrated cooling system for high power batteries that can limit the residual heat in the battery cells. Results from experiments will be presented, both at the cell and the module level.

AB The U.S. Navy has invested considerable funds in the research and development of electrical power technologies for future electric warships. One aspect of institutionalizing these technologies is the creation or modification of standards and specifications to incorporate the new technologies. This paper assesses the current state of standards and specifications in support of the design and construction of an all-electric naval warship. These technical documents will be evaluated in terms of the different power systems architectures to include low voltage ac generation, medium voltage ac generation, medium voltage dc generation, and zonal power distribution. Ongoing standards activity, both in industry and in the Navy, are discussed. Finally, the paper presents recommendations for updating existing specifications and standards and the creation of new specifications to cover technical areas where standards do not currently exist.

AB Electrical power demands for naval surface combatants are projected to rise with the development of increasingly complex and power intensive combat systems. This trend coincides with the need to achieve maximum fuel efficiency at both high and low hull speeds. A proposed solution to meet current and future energy needs of conventionally powered naval surface combatants is through the use of an Integrated Power System (IPS), which is seen as the next evolution in naval ship design. In an effort to enhance the relationship between new-concept designs and historically-based ship design processes, this paper focuses on a novel approach of incorporating IPS at the earliest stage of the design process as part of assessing system-level tradeoffs early within the ship design process.
This paper describes a methodology for the systematic design and arrangement of an IPS machinery plant to meet a desired power generation level. In conjunction with the methodology development, a hierarchical process and design tool were produced to assist in rapid development and evaluation of various IPS arrangements. The result of this process, through several case studies, provides insight into equipment selection philosophy, the initial sizing of the ship's machinery box, and the initial definition of electrical zones.

TI Improved Doppler Velocity Dealiasing for Radar Data Assimilation and

ID DATA QUALITY-CONTROL
AB The Doppler velocity dealiasing technique based on alias-robust VAD and variational (AR-Var) analyses developed at the National Severe Storms Laboratory for radar data quality control and assimilation is further improved in its two-step procedures: the reference check in the first step and the continuity check in the second step. In the first step, the alias-robust variational analysis is modified adaptively and used in place of the alias-robust velocity-azimuth display (VAD) analysis for all scan modes (rather than solely theWSR-88D volume coverage pattern 31 with the Nyquist velocity V.. reduced below 12 m s(-1) and the TDWR Mod80 with nu(N). reduced below 15 m s(-1)), so more raw data can pass the stringent threshold conditions used by the reference check in the first step. This improves the dealiased data coverage without false dealiasing to better satisfy the high data quality standard required by radar data assimilation. In the second step, new procedures are designed and added to the continuity check to increase the dealiased data coverage over storm-scale areas threatened by intense mesocyclones and their generated tornados. The performances of the improved dealiasing technique versus the existing techniques are exemplified by the results obtained for tornadic storms scanned by the operational KTLX radar in Oklahoma.

AB Blast-related ear injuries are a concern during deployment because they can compromise a servicemember's situational awareness and adversely affect operational readiness. The objectives of this study were to describe blast-related ear injuries during Operation Iraqi Freedom, identify the effect of hearing protection worn at the point of injury, and explore hearing loss and tinnitus outcomes within one year after injury. The Expeditionary Medical Encounter Database was used to identify military personnel who survived blast-related injury, and it was linked with outpatient medical databases to obtain diagnoses of hearing loss and tinnitus. The prevalence of ear injuries was 30.7% (1,223 of 3,981). The most common ear injury diagnoses were "inner or middle ear injury involving tinnitus" and tympanic membrane (TM) rupture. Hearing protection reduced the odds of ear injury involving tinnitus. Personnel with TM rupture had higher odds of hearing loss (odds ratio [OR] = 6.65, 95% confidence interval [CI] = 5.04-8.78) and tinnitus outcomes (OR = 4.34, 95% CI = 3.12-6.04) than those without TM rupture. Ear injuries and hearing impairment are frequent consequences of blast exposure during combat deployment. Hearing protection is warranted for all service-members at risk of blast exposure.

AB Influenza viruses cause recurring epidemic outbreaks every year associated with high morbidity and mortality. Despite extensive research and surveillance efforts to control influenza outbreaks, the primary mitigation treatment for influenza is the development of yearly vaccine mixes targeted for the most prevalent virus strains. Consequently, the focus of many detection technologies has evolved toward accurate identification of subtype and understanding the evolution and molecular determinants of novel and pathogenic forms of influenza. The recent availability of potential antiviral treatments are only effective if rapid and accurate diagnostic tests for influenza epidemic management are available; thus, early detection of influenza infection is still important for prevention, containment, patient management, and infection control. This review discusses the current and emerging technologies for detection and strain identification of influenza virus and their specific gene targets, as well as their implications in patient management.

AB One of the major scientific thrusts from recent years has been to try to harness quantum phenomena to dramatically increase the performance of a wide variety of classical devices. These advances in quantum information science have had a considerable impact on the development of photonic-based quantum sensors. Even though quantum radar and quantum lidar remain theoretical proposals, preliminary results suggest that these sensors have the potential of becoming disruptive technologies able to revolutionize reconnaissance systems. In this paper we will discuss how quantum entanglement can be exploited to increase the radar and lidar signature of rectangular targets. In particular, we will show how the effective visibility of the target is increased if observed with an entangled multi-photon quantum sensor.

ID CHLORINE MONOXIDE; DIURNAL-VARIATION
AB We present a re-analysis of upper stratospheric ClO measurements from the ground-based millimeter-wave instrument from January 1992 to February 2012. These measurements are made as part of the Network for the Detection of Atmospheric Composition Change (NDACC) from Mauna Kea, Hawaii, (19.8 degrees N, 204.5 degrees E). Here, we use daytime and nighttime measurements together to form a day-night spectrum, from which the difference in the day and night profiles is retrieved. These results are then compared to the daynight difference profiles from the Upper Atmosphere Research Satellite (UARS) and Aura Microwave Limb Sounder (MLS) instruments. We also compare them to our previous analyses of the same data, in which we retrieved the daytime ClO profile. The major focus will be on comparing the year-to-year and long-term changes in ClO derived by the two analysis methods, and comparing these results to the longterm changes reported by others. We conclude that the reanalyzed data set has less short-term variability and exhibits a more constant long-term trend that is more consistent with other observations. Data from 1995 to 2012 indicate a linear decline of mid-stratospheric ClO of 0.64 +/- 0.15% yr(-1) (2 sigma).

AB In the aquatic environment, particles can be broadly separated into phytoplankton (PHY), non-algal particle (NAP) and dissolved (or very small particle, VSP) fractions. Typically, absorption spectra are inverted to quantify these fractions, but volume scattering functions (VSFs) can also be used. Both absorption spectra and VSFs were used to estimate particle fractions for an experiment in the Chesapeake Bay. A complete set of water inherent optical properties was measured using a suite of commercial instruments and a prototype Multispectral Volume Scattering Meter (MVSM); the chlorophyll concentration, [Chl] was determined using the HPLC method. The total scattering coefficient measured by an ac-s and the VSF at a few backward angles measured by a HydroScat-6 and an ECO-VSF agreed with the LISST and MVSM data within 5 %, thus indicating inter-instrument consistency. The size distribution and scattering parameters for PHY, NAP and VSP were inverted from measured VSFs. For the absorption inversion, the "dissolved" absorption spectra were measured for filtrate passing through a 0.2 mu m filter, whereas [Chl] and NAP absorption spectra were inverted from the particulate fraction. Even though the total scattering coefficient showed no correlation with [Chl], estimates of [Chl] from the VSF-inversion agreed well with the HPLC measurements (r = 0.68, mean relative errors = -20 %). The scattering associated with NAP and VSP both correlated well with the NAP and "dissolved" absorption coefficients, respectively. While NAP dominated forward, and hence total, scattering, our results also suggest that the scattering by VSP was far from negligible and dominated backscattering. Since the sizes of VSP range from 0.02 to 0.2 mu m, covering (a portion of) the operationally defined "dissolved" matter, the typical assumption that colored dissolved organic matter (i.e., CDOM) does not scatter may not hold, particularly in a coastal or estuarine environment.

ID LIQUID SCINTILLATORS
AB Pulse shape discrimination (PSD) is a common method to distinguish between pulses produced by gamma rays and neutrons in scintillator detectors. This technique takes advantage of the property of many scintillators that excitations by recoil protons and electrons produce pulses with different characteristic shapes. Unfortunately, many scintillating materials with good PSD properties have other, undesirable properties such as flammability, toxicity, low availability, high cost, and/or limited size. In contrast, plastic scintillator detectors are relatively low-cost, and easily handled and mass-produced. Recent studies have demonstrated efficient PSD in plastic scintillators using a high concentration of fluorescent dyes. To further investigate the PSD properties of such systems, mixed plastic scintillator samples were produced and tested. The addition of up to 30 wt. % diphenyloxazole (DPO) and other chromophores in polyvinyltoluene (PVT) results in efficient detection with commercial detectors. These plastic scintillators are produced in large diameters up to 4 inches by melt blending directly in a container suitable for in-line detector use. This allows recycling and reuse of materials while varying the compositions. This strategy also avoids additional sample handling and polishing steps required when using removable molds. In this presentation, results will be presented for different mixed-plastic compositions and compared with known scintillating materials

ID LIGHT-SCATTERING; FLUORESCENCE
AB The goal of this project is to investigate correlations of polarimetric angular scattering patterns from individual aerosol particles with the particles' physical structure and composition. Such signature patterns may be able to provide particle classification capability, such as, for example, discrimination between man-made and naturally occurring aerosols. If successful, this effort could improve current detection methods for biological warfare (BW) agent aerosols. So far, we have demonstrated an experimental arrangement to measure polarization-state resolved, multi-angle, scattering intensities from single aerosol particles on-the-fly. Our novel approach is a radical departure from conventional polarimetric measurement methods, and a key factor is the use of a multiple-order retarder to prepare different polarization states, depending on the wavelength of the incident light. This novel experimental technique uses a super-continuum light source, an array of optical fibers, an imaging spectrometer and an EMCCD camera to simultaneously acquire wavelength and angle dependent particle light scattering data as a two-dimensional snapshot.
Mueller matrix elements were initially measured from individual particles held in an optical trap (at 405 nm). Since particles can be stably trapped for long periods (hours), we were able to change the optical configuration to acquire multiple Mueller matrix element measurements on a single particle. We have computationally modeled these measurements at specific angles, and the comparison with experimental measurements shows good agreement. Similar measurements have also been made on slowly falling particles, and our current efforts are focused on improving experimental technique sufficiently to make such measurements on flowing particles.

AB Trace or residue explosives detection typically involves examining explosives found as solid particles on a solid substrate. Different optical spectroscopy techniques are being developed to detect these explosives in situ by probing how light interacts with the surface bound particles of explosives. In order to evaluate these technologies it is important to have available suitable test coupons coated with particles of explosives. When fabricating test coupons to evaluate detection performance or help train a detection algorithm, it is important to use realistic test coupons and consider how the physicochemical properties of the explosives particles, related chemicals, and substrate may affect the spectra produced or signal intensities observed. Specific features of interest include surface fill factor, particle sizes, areal density, degree of particle contact with a substrate and any other chemicals in addition to the explosives and substrate. This level of complexity highlights the need to fabricate test coupons which mimic "real world" particle coated surfaces.
With respect to metrics derived from fingerprints, we compare the properties of test coupons fabricated by sieving and inkjetting for ammonium nitrate, TNT, RDX, and sucrose on stainless steel, automotive painted steel, glass and polyethylene substrates. Sieving provides a random distribution of particles, allows fractionation of relevant particle sizes and allows relevant surface fill factors to be achieved. Inkjetting provides precise control of aerial density but because of complications related to solvent-substrate interactions, relevant fill factors and particle sizes are difficult to achieve. In addition, we introduce a custom image analysis technique, NRL ParticleMath, developed to characterize and quantify particle loadings on test coupons.

AB Blast waves ignited in a supersonic flow are capable of producing density profiles useful for laser acceleration of electrons and ions. By using a approximate to 0.1 joule nanosecond laser as an igniter, and controlling the angle of incidence and timing of the ultra-intense femtosecond drive pulse, one can produce a variety of gas density profiles. A profile with an abrupt up-ramp followed by a gradual down-ramp leads experimentally to stable generation of 40 MeV electrons from a 10 TW drive pulse. A profile with a narrow high density region, and a steep density ramp on one side, is useful for magnetic vortex acceleration of ions. Simulations predict that such a profile can be generated from a laser ignited blast wave, and that 35 MeV protons are produced when a 100 TW pulse is focused into the shock front.

AB Guillaume Postel is often credited as one of the founding fathers of the modern "orientalist" European study of the Middle East, and of Arabic, Islam, and the Quran in particular. He published his most influential work in 1544, calling on the French king to lead a Crusade against the Ottomans and usher in a new, apocalyptic age. Although usually credited as a pioneer in the comparative study of Semitic languages, an influential figure in French-Ottoman relations, and as one of the first Europeans to study the Quran in comparison with the Bible, it was the unique sixteenth-century renaissance combination of apocalyptism, European nationalism, and alchemy behind the specific formation of Postel's universal linguistic theories that would most influence future scholarship. The following pages examine the historical context in which Postel produced his work with particular attention to the apocalyptism of his religious ideas and the kabbalistic sources of his linguistic scholarship.

Specifically, the proposed control method utilizes an iterative learning estimator that is designed in order to promote system stability and asymptotically regulate the laser's target position to a desired location. The learning estimator requires that the disturbance be bounded and its period to be known. Simulation and experimental results are provided to demonstrate the efficacy of the proposed method.

AB Both maximum likelihood estimation as well as minimum mean optimal subpattern assignment (MMOSPA) estimation have been shown to provide meaningful estimates in instances of target identity uncertainty when the number of targets present is known. Maximum likelihood measurement to track association (2D assignment) has been widely studied and is reviewed in this paper. However, it is widely believed that approximate MMOSPA estimation can not be performed in real time except when considering a very small number of targets. This paper demonstrates the MMOSPA estimator arises as a special case of a minimum mean Wasserstein metric estimator when the number of targets is unknown. Additionally, it is shown that approximate MMOSPA estimates can be calculated in microseconds to miliseconds without extensive optimization, making MMOSPA estimation a practicable alternative to more traditional estimators.

AB We are developing a technique for the stand-off detection of trace explosives on relevant substrate surfaces using photo-thermal infrared (IR) imaging spectroscopy (PT-IRIS). This approach leverages one or more compact IR quantum cascade lasers, tuned to strong absorption bands in the analytes and directed to illuminate an area on a surface of interest. An IR focal plane array is used to image the surface and detect small increases in thermal emission upon laser illumination. The PT-IRIS signal is processed as a hyperspectral image cube comprised of spatial, spectral and temporal dimensions as vectors within a detection algorithm. The ability to detect trace analytes on relevant substrates is critical for stand-off applications, but is complicated by the optical and thermal analyte/substrate interactions. This manuscript describes recent PT-IRIS experimental results and analysis for traces of RDX, TNT, ammonium nitrate (AN) and sucrose on relevant substrates (steel, polyethylene, glass and painted steel panels). We demonstrate that these analytes can be detected on these substrates at relevant surface mass loadings (10 mu g/cm(2) to100 mu g/cm(2)) even at the single pixel level.

AB We demonstrate plasmonic enhancement of visible-light-driven splitting of water at three-dimensionally (3D) networked gold-titania (Au-TiO2) aerogels. The sol-gel-derived ultraporous composite nanoarchitecture, which contains 1 to 8.5 wt% Au nanoparticles and titania in the anatase form, retains the high surface area and mesoporosity of unmodified TiO2 aerogels and maintains stable dispersion of the similar to 5 nm Au guests. A broad surface plasmon resonance (SPR) feature centered at similar to 550 nm is present for the Au-TiO2 aerogels, but not Au-free TiO2 aerogels, and spans a wide range of the visible spectrum. Gold-derived SPR in Au-TiO2 aerogels cast as films on transparent electrodes drives photoelectrochemical oxidation of aqueous hydroxide and extends the photocatalytic activity of TiO2 from the ultraviolet region to visible wavelengths exceeding 700 nm. Films of Au-TiO2 aerogels in which Au nanoparticles are deposited on pre-formed TiO2 aerogels by a deposition-precipitation method (DP Au/TiO2) also photoelectrochemically oxidize aqueous hydroxide, but less efficiently than 3D Au-TiO2, despite having an essentially identical Au nanoparticle weight fraction and size distribution. For example, 3D Au-TiO2 containing 1 wt% Au is as active as DP Au/TiO2 with 4 wt% Au. The higher photocatalytic activity of 3D Au-TiO2 derives only in part from its ability to retain the surface area and porosity of unmodified TiO2 aerogel. The magnitude of improvement indicates that in the 3D arrangement either a more accessible photoelectrochemical reaction interphase (three-phase boundary) exists or more efficient conversion of excited surface plasmons into charge carriers occurs, thereby amplifying reactivity over DP Au/TiO2. The difference in photocatalytic efficiency between the two forms of Au-TiO2 demonstrates the importance of defining the structure of Au vertical bar vertical bar TiO2 interfaces within catalytic Au-TiO2 nanoarchitectures.

AB The technology of direct digital additive manufacturing (D2AM) has received considerable attention in recent months. Several government agencies and commercial interests are planning to explore D2AM to find solutions to manufacturing problems. The attraction of D2AM is the benefit of rapidly producing without fixtures or tools or human intervention customized objects of complex geometry not possible by traditional methods. The interest in D2AM ranges from fabrication of critical, high value aerospace metallic components to fabrication of objects having an organic look or as nature would have intended(i). For D2AM to be commercially accepted, it must reliably and predictably make products. It must achieve consistency in reproducibility across relevant D2AM methods. The Office of Naval Research (ONR) has launched a new basic research program, known as Cyber-enabled Manufacturing Systems (CeMS). The long-range goal of the program is to achieve the level of control over D2AM processes for industrial acceptance and wide-use of the technology. This program will develop measuring, sensing and control models and algorithms for D2AM by harnessing principles underpinning cyber-physical systems (CPS) and fundamentals of physical processes. This paper describes the challenges facing D2AM and the CeMS program goals to meet them.

ID ARCHITECTURES; RESTORATION
AB This paper demonstrates methods to select and apply regularization to the linear least-squares model formulation of the radio tomographic imaging (RTI) problem. Typically, the RTI inverse problem of image reconstruction is ill-conditioned due to the extremely small singular values of the weight matrix which relates the link signal strengths to the voxel locations of the obstruction. Regularization is included to offset the non-invertible nature of the weight matrix by adding a regularization term such as the matrix approximation of derivatives in each dimension based on the difference operator. This operation yields a smooth least-squares solution for the measured data by suppressing the high energy or noise terms in the derivative of the image. Traditionally, a scalar weighting factor of the regularization matrix is identified by trial and error (adhoc) to yield the best fit of the solution to the data without either excessive smoothing or ringing oscillations at the boundaries of the obstruction. This paper proposes new scalar and vector regularization methods that are automatically computed based on the weight matrix. Evidence of the effectiveness of these methods compared to the preset scalar regularization method is presented for stationary and moving obstructions in an RTI wireless sensor network. The variation of the mean square reconstruction error as a function of the scalar regularization is calculated for known obstructions in the network. The vector regularization procedure based on selective updates to the singular values of the weight matrix attains the lowest mean square error.

AB The potential of compressive sensing (CS) has spurred great interest in the research community and is a fast growing area of research. However, research translating CS theory into practical hardware and demonstrating clear and significant benefits with this hardware over current, conventional imaging techniques has been limited. This article helps researchers to find those niche applications where the CS approach provides substantial gain over conventional approaches by articulating lessons learned in finding one such application; sea skimming missile detection. As a proof of concept, it is demonstrated that a simplified CS missile detection architecture and algorithm provides comparable results to the conventional imaging approach but using a smaller FPA.

AB While conducting a cutting-edge research in a specific domain, we realize that (1) requirements clarity and correctness are crucial to our success [1], (2) hardware is hard to change, most work is in software requirements development, coding and testing [2], (3) requirements are constantly changing, so that configurability, reusability, scalability, adaptability, modularity and testability are important non-functional attributes [3], (4) cross-domain knowledge is necessary for complex systems [4], and (5) if our research is successful, the results could be applied to other domains with similar problems. In this paper, we propose to use model-driven requirements engineering (MDRE) to model and guide our requirements/development, since models are easy to understand, execute, and modify. The domain for our research is Electronic Warfare (EW) real-time ultra-wide instantaneous bandwidth (IBW1) signal simulation. The proposed four MDRE models are (1) Switch-and-Filter architecture, (2) multiple parallel data bit streams alignment, (3) post-ADC and pre-DAC bits re-mapping, and (4) Discrete Fourier Transform (DFT) filter bank. This research is unique since the instantaneous bandwidth we are dealing with is in gigahertz range instead of conventional megahertz.

AB The capabilities of tactical intelligence, surveillance, and reconnaissance (ISR) payloads are expanding from single sensor imagers to integrated systems-of-systems architectures. Increasingly, these systems-of-systems include multiple sensing modalities that can act as force multipliers for the intelligence analyst. Currently, the separate sensing modalities operate largely independent of one another, providing a selection of operating modes but not an integrated intelligence product. We describe here a Sensor Management System (SMS) designed to provide a small, compact processing unit capable of managing multiple collaborative sensor systems on-board an aircraft. Its purpose is to increase sensor cooperation and collaboration to achieve intelligent data collection and exploitation. The SMS architecture is designed to be largely sensor and data agnostic and provide flexible networked access for both data providers and data consumers. It supports pre-planned and ad-hoc missions, with provisions for on-demand tasking and updates from users connected via data links. Management of sensors and user agents takes place over standard network protocols such that any number and combination of sensors and user agents, either on the local network or connected via data link, can register with the SMS at any time during the mission. The SMS provides control over sensor data collection to handle logging and routing of data products to subscribing user agents. It also supports the addition of algorithmic data processing agents for feature/target extraction and provides for subsequent cueing from one sensor to another. The SMS architecture was designed to scale from a small UAV carrying a limited number of payloads to an aircraft carrying a large number of payloads. The SMS system is STANAG 4575 compliant as a removable memory module (RMM) and can act as a vehicle specific module (VSM) to provide STANAG 4586 compliance (level-3 interoperability) to a non-compliant sensor system. The SMS architecture will be described and results from several flight tests and simulations will be shown.

AB The Hyperspectral Imager for the Coastal Ocean (HICO) is a prototype sensor installed on the International Space Station (ISS) designed to explore the management and capability of a space-borne hyperspectral sensor. The Office of Naval Research (ONR) funded the development and management of HICO. The Naval Research Laboratory (NRL) built and is involved in management of the HICO sensor. Bathymetry information is essential for naval operations in coastal regions. However, bathymetry may not be available in denied areas. HICO has a 100 meter spatial resolution, which makes it more capable for providing information within bays and estuaries than other sensors with coarser resolutions. Furthermore, its contiguous hyperspectral range is well suited to be used as input to the Hyperspectral Optimization Process Exemplar (HOPE) algorithm, which along with other absorption and backscattering values, estimates bottom albedo and water depth. Vicarious calibration uses in situ data to generate new gains and offsets that when applied to the top-of-atmosphere radiance values improves atmospheric correction results and the measurement of normalized water-leaving radiances. In situ remote sensing reflectance data collected in St. Andrews Bay were used to vicariously calibrate a coincident HICO scene. NRL's Automated Processing System (APS) was used to perform atmospheric correction and estimation of remote sensing reflectance (Rrs). The HOPE algorithm used the vicariously calibrated HICO Rrs values to estimate water depth. The results were validated with bathymetry maps from the NOAA National Ocean Service (NOS).

DE sea surface temperature; VIIRS satellite; remote sensing; full swath
AB The ultimate goal of the prediction of Sea Surface Temperature (SST) from satellite data is to attain an accuracy of 0.3 degrees K or better when compared to floating or drifting buoys located around the globe. Current daytime SST algorithms are able to routinely achieve an accuracy of 0.5 degrees K for satellite zenith angles up to 53 degrees. The full scan swath of VIIRS (Visible Infrared Imaging Radiometer Suite) results in satellite zenith angles up to 70 degrees, so that successful retrieval of SST from VIIRS at these higher angles would greatly increase global coverage. However, the accuracy of present SST algorithms steadily degrades to nearly 0.7 degrees K as the satellite zenith angle reaches 70 degrees, due mostly to the effects of increased atmospheric path length. We investigated the use of T-field, a gap-free first guess temperature field used in NLSST, as a separate predictor to the MCSST algorithm in order to clearly evaluate its effects. Results of this new algorithm, TfieldSST, showed how its rms error is heavily dependent on the aggressiveness of the pre-filtering of buoy matchup data with respect to Tfield. It also illustrated the importance of fully exploiting the a priori satellite-only information contained in T-field, presently tamed in the NLSST algorithm due to the fact that it shows up as a multiplier to another predictor. Preliminary results show that SST retrievals using TfieldSST could be obtained using the full satellite swath with a 30% improvement in accuracy at large satellite zenith angles and that a fairly aggressive pre-filtering scheme could help attain the desired accuracy of 0.3 degrees K or better using over 75% of the buoy matchup data.

AB The detection and identification of underwater threats in coastal areas is of interest to the Navy. Conventional optical imaging systems are limited to scenarios where the number of attenuation lengths between the system and the object are less than 4. With a desire to operate at extended ranges and threats becoming smaller and better camouflaged, new approaches are needed. In response to these challenges, new transmitters and receivers are being developed to support the next-generation of underwater optical imaging systems. One of these systems is based on the modulated pulse concept where a pulsed laser source is encoded with a radar signal, and a range-gated, high-speed optical receiver recovers the radar modulation envelope. Subsequent processing of the radar signal provides a way to discriminate against multiply scattered light and to enhance image contrast and resolution. The challenge is developing transmitter and receiver hardware that meets the requirements of the modulated pulse technique. We report recent progress that has been made in developing modulated pulse transmitter and receiver hardware. A working prototype was demonstrated and tested in a controlled laboratory environment. The results of these initial experiments are presented.

Estimated coupled bio-optical, physical error covariances are used in the Kalman gain update providing updates of coupled bio-optical properties in accord with the model dynamics and available observations. With the assimilation of satellite-derived bio-optical properties (chlorophyll-a and absorption due to phytoplankton), the model was able to reproduce intensity and tendencies in subsurface chlorophyll distributions observed at water samples locations in the Monterey Bay, CA. Data assimilation also improved agreement between the observed and model-predicted ratios between diatoms and small phytoplankton populations.

AB The tracking of missiles at close range proximity has been an ongoing challenge for many launch environments. The ability to provide accurate missile trajectory information is imperative for range safety and early termination of flight. In an effort to provide a potential solution to tracking issues that have plagued many traditional techniques, the Tracking Interferometer Pathfinder System (TIPS) was developed at the Naval Research Laboratory, Washington, D. C. The paper herein describes the design, field test, and results of an interferometer deployed for missile tracking.

AB Spinel is a rugged ceramic transparent from ultraviolet to midwave infrared (0.18 - 5.5 mu m) wavelengths. It has the best transmission from 4-5 mu m among the competing materials ALON and sapphire with comparable mechanical properties. We have developed low absorption loss spinel as an exit window aperture for High Energy Laser systems. We demonstrated that spinel possesses excellent thermo-optical characteristics required for the High Energy Laser systems and at the same time it can provide the necessary ruggedness desired for the realistic and harsh battlefield environment. We have demonstrated through testing that spinel can withstand very adverse conditions of rain, sand storms and salt fog conditions without any change in its optical performance. We have also developed rugged anti-reflective coatings and anti-reflective surface structures to maintain high optical transmission in adverse environment.

The technique will permit detection of corrosion on and within aircraft structures and component junctions that are susceptible to corrosion, but which are not accessible for visual inspection. The field application configuration includes surface and embedded optical fiber probes interfaced with a Fourier Transform Infrared (FTIR) interferometer for evanescent wave absorption spectroscopic measurements. The mature and fielded technique will allow periodic remote sensing for structural health monitoring and detection of corrosion.
The potential advantages of optical fiber sensors result from the fact that the sensing element, the optical fiber, is small size, light weight, and immune to electromagnetic field. Also it can be attached to surfaces or embedded in junctions in aircraft structures, in locations where humidity and corrosion can accumulate, but cannot be directly observed.

AB The utilization of unmanned aerial systems (UASs) for intelligence, surveillance and reconnaissance (ISR) applications continues to increase and unmanned systems have become a critical asset in current and future battlespaces. With the development of medium-to-low altitude, rapidly deployable aircraft platforms, the ISR community has seen an increasing push to develop ISR sensors and systems with real-time mission support capabilities. This paper describes the design and development of the RASAR (Real-time, Autonomous, Synthetic Aperture Radar) sensor system and presents demonstration flight test results. RASAR is a modular, multi-band (L and X) synthetic aperture radar (SAR) imaging sensor designed for self-contained, autonomous, real-time operation with mission flexibility to support a wide range of ISR needs within the size, weight and power constraints of Group III UASs. SAR waveforms are generated through direct digital synthesis enabling arbitrary waveform notching to enable operations in cluttered RF environments. RASAR is capable of simultaneous dual-channel receive to enable polarization based target discrimination. The sensor command and control and real-time image formation processing are designed to enable integration of RASAR into larger, multi-intelligence system of systems. The multi-intelligence architecture and a demonstration of real-time autonomous cross-cueing of a separate optical sensor will be presented.

AB There is a growing need for chemical imaging techniques in many fields of science and technology: forensics, materials science, pharmaceutical and chemical industries, just to name a few. While FTIR micro-spectroscopy is commonly used, its practical resolution limit of about 20 microns or more is often insufficient. Raman micro-spectroscopy provides better spatial resolution (similar to 1 micron), but is not always practical because of samples exhibiting fluorescence or low Raman scattering efficiency. We are developing a non-contact and non-destructive technique we call photo-thermal infrared imaging spectroscopy (PT-IRIS). It involves photo-thermal heating of the sample with a tunable quantum cascade laser and measuring the resulting increase in thermal emission with an infrared detector. Photo-thermal emission spectra resemble FTIR absorbance spectra and can be acquired in both stand-off and microscopy configurations. Furthermore, PT-IRIS allows the acquisition of absorbance-like photo-thermal spectra in a reflected geometry, suitable for field applications and for in-situ study of samples on optically IR-opaque substrates (metals, fabrics, paint, glass etc.). Conventional FTIR microscopes in reflection mode measure the reflectance spectra which are different from absorbance spectra and are usually not catalogued in FTIR spectral libraries. In this paper, we continue developing this new technique. We perform a series of numerical simulations of the laser heating of samples during photo-thermal microscopy. We develop parameterized formulas to help the user pick the appropriate laser illumination power. We also examine the influence of sample geometry on spectral signatures. Finally, we measure and compare photo-thermal and reflectance spectra for two test samples.

AB Currently there are extensive modeling and measurement capabilities for the region extending from 100 ft above sea surface to space, but few such capabilities exist for the region extending up to 10 ft above the sea surface. By measuring and characterizing conditions in the marine boundary layer existing below 30 ft above the sea surface such as turbulence and extinction, the optical communication capabilities of maritime vessels when operating at or near the surface may be extended and enhanced. Key physical parameters such as absorption, scattering, and turbulence strength (C-n(2)) along the propagation path have a degree of variability on meteorological conditions as well optical wavelength. Modeling of the atmospheric environment is thus critical in order to generate a good understanding of optical propagation through the atmosphere. NUWC is utilizing software provided by MZA to model C-n(2) and resultant beam propagation characteristics through the near-marine boundary layer. We are developing the capability of near-marine boundary layer atmospheric and turbulence measurements and modeling as well as optical laser link testing at outdoor test sites. Measurements are performed with optical laser links (e. g., bit rate error), scintillometer, and particle image velocimetry (PIV) cameras, while turbulence and propagation modeling is achieved using MODTRAN5, ATMTools, NSLOT, LEEDR, and WaveTrain modeling and simulation code. By better understanding the effects of turbulence on optical transmission in the near-marine boundary layer through modeling and experimental measurements, measures can be implemented to reduce the bit error rate and increase data throughput, enabling more efficient and accurate communication link capabilities.

AB Low-thermal-expansion tungstate materials have the potential to be used as thermal-shock-resistant midwave (3-5 mu m) infrared windows. Material properties that favor thermal shock resistance are high strength, high thermal conductivity, low elastic modulus, and low thermal expansion. Sapphire, for example, owes its high thermal shock resistance to high strength and high thermal conductivity. In principle, it is possible to obtain even higher thermal shock resistance if a window material with near-zero thermal expansion can be made. This paper assesses recent work on Zr(WO4)(2) and Al0.5Sc1.5(WO4)(3). It is concluded that multi-phonon absorption in the midwave spectral region limits the optical capabilities of tungstate materials. These materials have more absorption-and therefore, more emission-than aluminum oxynitride in the 4-5 mu m wavelength region.

AB The deposition of nano-crystalline ZnS/diamond composite protective coatings on silicon, sapphire, and ZnS substrates, as a preliminary step to coating infrared transparent ZnS substrates from powder mixtures by the aerosol deposition method is presented. Advantages of aerosol deposition method include the ability to form dense, nanocrystalline films up to hundreds of microns thick at room temperature and at a high deposition rate on a variety of substrates. Deposition is achieved by creating a pressure gradient that accelerates micrometer-scale particles in an aerosol to high velocity. Upon impact with the target substrate the particles fracture and embed. Continued deposition forms the thick compacted film. Deposition from an aerosolized mixtures of ZnS and diamond powders onto all targets results in linear trend from apparent sputter erosion of the substrate at 100% diamond to formation of a film with increasing fractions of ZnS. The cross from abrasion to film formation on sapphire occurs above about 50% ZnS and a mixture of 90% ZnS and 10% diamond forms a well-adhered film of about 0.7 mu m thickness at a rate of 0.14 mu m/min. Resulting films are characterized by scanning electron microscopy, profilometry, infrared transmission spectroscopy, and x-ray photoemission spectroscopy. These initial films mark progress toward the future goal of coating ZnS substrates for abrasion resistance.

AB This paper examines the signature characteristics of moving targets in spotlight synthetic aperture radar (SAR) image data. This analysis considers the special case in which the radar sensor is assumed to move with constant speed and heading on a level flight path with broadside imaging geometry. It is shown that the resulting defocused smear signature in the spotlight SAR image exhibits range migration effects, as has been shown previously for stripmap SAR analysis. In particular, cases of uniform target motion exhibit simply curved range migration paths, whereas non-uniform target motion can cause complicated smear shapes.

AB The Naval Research Laboratory (NRL) has extensively investigated atmospheric effects on maritime lasercomm in both long term research studies and short term system demonstrations. A current effort is underway in the ONR Tactical Line-of-Sight Optical Communications (TALON) program to better characterize atmospheric transmission at 1550 nm in multiple climates to enable prediction of communication link performance. In order to allow long term unmanned measurements in these multiple climates, NRL developed a scattering-based 1550 nm transmission sensor similar in function to commercial visible wavelength visibility monitors. After the system was built and calibrated, it was deployed to a number of sites with various climate types to collect data over a 1-month period for each site.

AB This paper examines the behavior in multilateral bargaining experiments with alternating offers and asymmetric information. In all experiments, a single buyer has up to ten bargaining periods to purchase one unit of a good from each of two sellers. Treatments vary based on who makes the first offer (buyer or sellers), timing (consistent buyer-offer/sellers-demand or alternating), and information (buyer's value and sellers' costs are known or come from a uniform distribution). We find that actual bargaining outcomes are virtually identical when offers alternate, regardless of which player makes the first offer. We find that alternating offers reduce bargaining delay slightly compared to treatments in which one side or the other makes repeated take-it-or-leave-it offers. Finally, we find that incomplete information increases bargaining delay and the likelihood of failed agreements.

AB LiDAR data are available in a variety of publicly-accessible forums, providing high-resolution, accurate 3-dimensional information about objects at the Earth's surface. Automatic extraction of information from LiDAR point clouds, however, remains a challenging problem. The focus of this research is to develop methods for point cloud classification and object detection which can be customized for specific applications. The methods presented rely on analysis of statistics of local neighborhoods of LiDAR points. A multi-dimensional vector composed of these statistics can be classified using traditional data classification routines. Local neighborhood statistics are defined, and examples are given of the methods for specific applications such as building extract ion and vegetation classification. Results indicate the feasibility of the local neighborhood statistics approach and provide a framework for the design of customized classification or object detection routines for LiDAR point clouds.

AB In this paper, we present our recent progress in the development of rare-earth (Yb3+ or Ho3+) doped Lu2O3 and Y2O3 sesquioxides for high power solid state lasers. We have fabricated high quality transparent ceramics using nano-powders synthesized by a co-precipitation method. This was accomplished by developments in high purity powder synthesis and low temperature scalable sintering technology developed at NRL. The optical, spectral and morphological properties as well as the lasing performance from our highly transparent ceramics are presented. In the second part of the paper, we discuss our recent research effort in developing cladded-single crystal fibers for high power single frequency fiber lasers has the potential to significantly exceed the capabilities of existing silica fiber based lasers. Single crystal fiber cores with diameters as small as 35 mu m have been drawn using high purity rare earth doped ceramic or single crystal feed rods by the Laser Heated Pedestal Growth (LHPG) process. Our recent results on the development of suitable claddings on the crystal fiber core are discussed.

DE Output power; interband cascade laser; mid-infrared; threshold power
density; internal loss; high-power operation
AB We discuss approaches to increasing the cw output power of the interband cascade lasers (ICLs) for the midwave infrared spectral region. While most of the attention to date has been focused on reducing the operating power of the ICL, the optimization for maximum output power proceeds in a different direction. We find that increasing the number of stage is beneficial, in that it boosts the slope efficiency with only a modest penalty due to higher threshold power density and extra heating. The critical figure of merit for realizing high-power ICLs is the internal loss, which can be estimated from the external differential quantum efficiency (EDQE) per stage. The internal loss can be controlled by varying the thickness of the low-doped GaSb separate-confinement layers (SCLs). We demonstrate room-temperature EDQEs approaching 45% for broad-area 7-stage ICLs with 800-nm-thick SCLs.

TI Bimodules over Cartan MASAs in von Neumann algebras, norming algebras,
and Mercer's Theorem
SO NEW YORK JOURNAL OF MATHEMATICS

ID OPERATOR-ALGEBRAS; SUBALGEBRAS; ISOMORPHISMS; COHOMOLOGY
AB In a 1991 paper, R. Mercer asserted that a Cartan bimodule isomorphism between Cartan bimodule algebras A(1) and A(2) extends uniquely to a normal *-isomorphism of the von Neumann algebras generated by A(1) and A(2) (Corollary 4.3 of Mercer, 1991). Mercer's argument relied upon the Spectral Theorem for Bimodules of Muhly, Saito and Solel, 1988 (Theorem 2.5, there). Unfortunately, the arguments in the literature supporting their Theorem 2.5 contain gaps, and hence Mercer's proof is incomplete.
In this paper, we use the outline in Pitts, 2008, Remark 2.17, to give a proof of Mercer's Theorem under the additional hypothesis that the given Cartan bimodule isomorphism is sigma-weakly continuous. Unlike the arguments contained in the above mentioned papers of Mercer and Muhly-Saito-Solel, we avoid the use of the machinery in Feldman-Moore, 1977; as a consequence, our proof does not require the von Neumann algebras generated by the algebras A(i) to have separable preduals. This point of view also yields some insights on the von Neumann subalgebras of a Cartan pair (M, D), for instance, a strengthening of a result of Aoi, 2003.
We also examine the relationship between various topologies on a von Neumann algebra M with a Cartan MASA D. This provides the necessary tools to parameterize the family of Bures-closed bimodules over a Cartan MASA in terms of projections in a certain abelian von Neumann algebra; this result may be viewed as a weaker form of the Spectral Theorem for Bimodules, and is a key ingredient in the proof of our version of Mercer's Theorem. Our results lead to a notion of spectral synthesis for sigma-weakly closed bimodules appropriate to our context, and we show that any von Neumann subalgebra of M which contains D is synthetic.
We observe that a result of Sinclair and Smith shows that any Cartan MASA in a von Neumann algebra is norming in the sense of Pop, Sinclair and Smith.

AB The electrical conduction properties of ruthenium oxide nanocables are of high interest. These cables can be built as thin shells of RuO2 surrounding an inner solid nanowire of a dielectric insulating silica material. With this motivation we have investigated the structural, electronic and transport properties of RuO2 nanotubes using the density functional formalism, and applying many-body corrections to the electronic band structure. The structures obtained for the thinnest nanotubes are of the rutile type. The structures of nanotubes with larger diameters deviate from the rutile structure and have in common the formation of dimerized Ru-Ru rows along the axial direction. The cohesive energy shows an oscillating behavior as a function of the tube diameter. With the exception of the thinnest nanotubes, there is a correlation such that the electronic band structures of tubes with high cohesive energies show small gaps at the Fermi energy, whereas the less stable nanotubes exhibit metallic behavior, with bands crossing the Fermi surface. The electronic conductance of nanotubes of finite length connected to gold electrodes has been calculated using a Green-function formalism, and correlations have been established between the electronic band structure and the conductance at zero bias.

The system will provide the basic design for an imaging/detection systems functioning at optical or infrared frequencies that offer better than classical angular and range resolution. Optimization for enhanced resolution will be included. The signal to noise ratio will be increased by a factor equal to the number of modes employed during the hyper-entanglement process. Likewise, the measurement time can be reduced by the same factor. The hyper-entanglement generator will typically make use of entanglement in polarization, energy-time, orbital angular momentum, etc. Mathematical results will be provided describing the system's performance as a function of loss mechanisms and noise.

TI CIB: An Improved Communication Architecture for Real-Time Monitoring of
Aerospace Materials, Instruments, and Sensors on the ISS
SO SCIENTIFIC WORLD JOURNAL
LA English
DT Article
AB The Communications Interface Board (CIB) is an improved communications architecture that was demonstrated on the International Space Station (ISS). ISS communication interfaces allowing for real-time telemetry and health monitoring require a significant amount of development. The CIB simplifies the communications interface to the ISS for real-time health monitoring, telemetry, and control of resident sensors or experiments. With a simpler interface available to the telemetry bus, more sensors or experiments may be flown. The CIB accomplishes this by acting as a bridge between the ISS MIL-STD-1553 low-rate telemetry (LRT) bus and the sensors allowing for two-way command and telemetry data transfer. The CIB was designed to be highly reliable and radiation hard for an extended flight in low Earth orbit (LEO) and has been proven with over 40 months of flight operation on the outside of ISS supporting two sets of flight experiments. Since the CIB is currently operating in flight on the ISS, recent results of operations will be provided. Additionally, as a vehicle health monitoring enabling technology, an overview and results from two experiments enabled by the CIB will be provided. Future applications for vehicle health monitoring utilizing the CIB architecture will also be discussed.

AB CdSe/ZnS semiconductor quantum dots (QDs) are ideal materials for biological sensing and cellular imaging applications due to their superior photophysical properties in comparison to fluorescent proteins or dyes and their ease of conjugation to biological materials. We have previously developed a number of in vitro FRET based biosensors in the laboratory for detection of proteases and biological and chemical agents. We would like to expand these biosensing capabilities into cellular systems, requiring development of QD cellular delivery techniques. Peptide-mediated cellular delivery of QDs is ideal as peptides are small, easily conjugated to QDs, easily manipulated and synthesized, and can be designed with "handles" for further chemical conjugation with other cargo. Here we discuss four cell delivery peptides that facilitate QD uptake in live cells. Understanding these peptides will help us design better nanoparticle cellular delivery systems and advance our capabilities for in vivo biosensing.

AB Single domain antibodies (sdAb) are variable domains cloned from camel, llama, or shark heavy chain only antibodies, and are among the smallest known naturally derived antigen binding fragments. SdAb derived from immunized llamas are able to bind antigens with high affinity, and most are capable of refolding after heat or chemical denaturation to bind antigen again. We hypothesized that the ability to produce heterodimeric sdAb would enable reagents with the robust characteristics of component sdAb, but with dramatically improved overall affinity through increased avidity. Previously we had constructed multimeric sdAb by genetically linking sdAb that bind non-overlapping epitopes on the toxin, ricin. In this work we explored a more flexible approach; the construction of multivalent binding reagents using multimerization domains. We expressed anti-ricin sdAb that recognize different epitopes on the toxin as fusions with differently charged leucine zippers. When the initially produced homodimers are mixed the leucine zipper domains will pair to produce heterodimers. We used fluorescence resonance energy transfer to confirm heterodimer formation. Surface plasmon resonance, circular dichroism, enzyme linked immunosorbent assays, and fluid array assays were used to characterize the multimer constructs, and evaluate their utility in toxin detection.

AB Atomic vapor cells with buffer gas have a number of advantages when employed as quantum memory blocks based on the DLCZ (Duan-Lukin-Cirac-Zoller) protocol: operation slightly above room temperature, ease of handling, as well as commercial availability. Nevertheless, the signal-to-noise ratio in the current implementations is severely limited by the simultaneous presence of collisional fluorescence and the four-wave mixing noise. In our previous work, we have shown how to minimize the influence of the former on the writing process and provided an unambiguous demonstration of quantum memory lasting for 4 mu s. An elegant approach to suppress the four-wave-mixing noise by pre-pumping to the state with the hyperfine sublevel with the maximum value was proposed by Walther et al., Int. J. Quantum Inform. 5, 51 (2007). Here we show that this approach is fundamentally limited by the cancellation of the Raman matrix elements involving the F' = 1 and F' = 2 levels, which occurs for all experimental conditions in the S -> P transitions of all alkali atoms. A detuning that maximizes the signal-to-noise ratio is shown to exist for a given detector dark-count rate.

AB Laboratory assessment of the adhesion of diatoms to non-toxic fouling-release coatings has tended to focus on single cells rather than the more complex state of a biofilm. A novel culture system based on open channel flow with adjustable bed shear stress values (0-2.4 Pa) has been used to produce biofilms of Navicula incerta. Biofilm development on glass and polydimethylsiloxane elastomer (PDMSe) showed a biphasic relationship with bed shear stress, which was characterised by regions of biofilm stability and instability reflecting cohesion between cells relative to the adhesion to the substratum. On glass, a critical shear stress of 1.3-1.4 Pa prevented biofilm development, whereas on PDMS, biofilms continued to grow at 2.4 Pa. Studies of diatom biofilms cultured on zwitterionic coatings using a bed shear stress of 0.54 Pa showed lower biomass production and adhesion strength on poly(sulfobetaine methacrylate) compared to poly (carboxybetaine methacrylate). The dynamic biofilm approach provides additional information to supplement short duration laboratory evaluations.

AB The ORR on Pt in an alkaline electrolyte is studied for the impact of support effects. Platinum nanoparticles are supported on nanoscale tantalum oxyphosphate or tantalum oxide films on Vulcan carbon (VC) to make either Pt/[TaOPO4/VC] or Pt/[Ta2O5/VC] electrocatalysts, which were then characterized with BF-STEM. Their ORR activity was determined by RDE methodology in 0.10 M KOH electrolyte. The Pt mass activities of the Pt/[TaOPO4/VC] and Pt/[Ta2O5/VC] electrocatalysts are both approximately 250 mA mg(Pt)(-1) at 0.925 V, or about 2 x greater than that of a commercial Pt/VC electrocatalyst (120 mA mg(Pt)(-1)), implying a substantial effect of the Ta-based support films.

AB Measurements of partially spatially coherent infra-red laser beam intensity fluctuations propagating through a hot-air turbulence emulator are compared with visible laser beam intensity fluctuations in the maritime and IR laser beam intensity fluctuations in the terrestrial environment at the United States Naval Academy. The emulator used in the laboratory for the comparison is capable of generating controlled optical clear air turbulence ranging from weak to strong scintillation. Control of the degree of spatial coherence of the propagating laser beam was accomplished using both infrared and visible spatial light modulators. Specific statistical analysis compares the probability density and temporal autocovariance functions, and fade statistics of the propagating laser beam between the in-laboratory emulation and the maritime field experiment. Additionally, the scintillation index across varying degrees of spatial coherence is compared for both the maritime and terrestrial field experiments as well as the in-laboratory emulation. The possibility of a scintillation index 'sweet' spot is explored.

AB The turbulent effects from the Earth's atmosphere degrade the performance of any optical system within it. There have been numerous studies in the effects of atmospheric turbulence on an imaging system that is pointed vertically to the sky looking at distant objects and the seeing conditions associated with it. We investigate the calculation of the seeing conditions with an imaging system pointed horizontally in terrestrial and maritime environments. We have acquired video data of different horizontal paths in the infrared wavelengths and performed data analysis that will be the basis of new characterizations and modeling of horizontal path atmospheric turbulence.

AB The relationship of magnetic clouds (MCs) to interplanetary coronal mass ejections (ICMEs) is still an open issue in space research. The view that all ICMEs would originate as magnetic flux ropes has received increasing attention, although near the orbit of the Earth only about one-third of ICMEs show clear MC signatures and often the MC occupies only a portion of the more extended region showing ICME signatures. In this work we analyze 79 events between 1996 and 2009 reported in existing ICME/MC catalogs (Wind magnetic cloud list and the Richardson and Cane ICME list) using near-Earth observations by ACE (Advanced Composition Explorer) and Wind. We perform a systematic comparison of cases where ICME and MC signatures coincided and where ICME signatures extended significantly beyond the MC boundaries. We find clear differences in the characteristics of these two event types. In particular, the events where ICME signatures continued more than 6 h past the MC rear boundary had 2.7 times larger speed difference between the ICME's leading edge and the preceding solar wind, 1.4 times higher magnetic fields, 2.1 times larger widths and they experienced three times more often strong expansion than the events for which the rear boundaries coincided. The events with significant mismatch in MC and ICME boundary times were also embedded in a faster solar wind and the majority of them were observed close to the solar maximum. Our analysis shows that the sheath, the MC and the regions of ICME-related plasma in front and behind the MC have different magnetic field, plasma and charge state characteristics, thus suggesting that these regions separate already close to the Sun. Our study shows that the geometrical effect (the encounter through the CME leg and/or far from the flux rope center) does not contribute much to the observed mismatch in the MC and ICME boundary times.

ATMOSPHERE; ACCIDENT; PACIFIC
AB The Great East Japan Earthquake and tsunami that caused a loss of power at the Fukushima nuclear power plants (FNPP) resulted in emission of radioactive isotopes into the atmosphere and the ocean. In June of 2011, an international survey measuring a variety of radionuclide isotopes, including Cs-137, was conducted in surface and subsurface waters off Japan. This paper presents the results of numerical simulations specifically aimed at interpreting these observations and investigating the spread of Fukushima-derived radionuclides off the coast of Japan and into the greater Pacific Ocean. Together, the simulations and observations allow us to study the dominant mechanisms governing this process, and to estimate the total amount of radionuclides in discharged coolant waters and atmospheric airborne radionuclide fallout. The numerical simulations are based on two different ocean circulation models, one inferred from AVISO altimetry and NCEP/NCAR reanalysis wind stress, and the second generated numerically by the NCOM model. Our simulations determine that >95% of Cs-137 remaining in the water within similar to 600 km of Fukushima, Japan in mid-June 2011 was due to the direct oceanic discharge. The estimated strength of the oceanic source is 16.2 +/- 1.6 PBq, based on minimizing the model-data mismatch. We cannot make an accurate estimate for the atmospheric source strength since most of the fallout cesium had left the survey area by mid-June. The model explained several key features of the observed Cs-137 distribution. First, the absence of Cs-137 at the southernmost stations is attributed to the Kuroshio Current acting as a transport barrier against the southward progression of Cs-137. Second, the largest Cs-137 concentrations were associated with a semi-permanent eddy that entrained Cs-137-rich waters, collecting and stirring them around the eddy perimeter. Finally, the intermediate Cs-137 concentrations at the westernmost stations are attributed to younger, and therefore less Cs-rich, coolant waters that continued to leak from the reactor in June of that year.

AB The demonstration of fine control over nanomaterials within biological systems, particularly in live cells, is integral for the successful implementation of nanoparticles (NPs) in biomedical applications. Here, we show the ability to differentially label the endocytic pathway of mammalian cells in a spatiotemporal manner utilizing fluorescent nanocolloids (NCs) doped with a perylene-based dye. EDC-based conjugation of green-and red-emitting NCs to the iron transport protein transferrin resulted in stable bioconjugates that were efficiently endocytosed by HEK 293T/17 cells. The staggered delivery of the bioconjugates allowed for the time-resolved, differential labeling of distinct vesicular compartments along the endocytic pathway in a nontoxic manner. We further demonstrated the ability of the NCs to be impregnated with the anticancer therapeutic, doxorubicin. Delivery of the drug-doped nanoconjugates resulted in the intracellular release and nuclear accumulation of doxorubicin in a time-and dose-dependent manner. We discuss our results in the context of the utility of such materials for NP-mediated drug delivery applications.

AB Biocompatible nanoparticles have recently attracted significant attention due to increasing interest in their use for biological sensing, cellular labeling and in vivo imaging. Semiconductor quantum dots (QDs) with good colloidal stability as well as small hydrodynamic sizes are particularly useful within these applications. We have developed a series of dihydrolipoic acid (DHLA) based surface ligands to enhance the colloidal stability and biocompatibility of water soluble QDs. Modification of DHLA with poly(ethylene glycol) derivatives provided the QDs with extended colloidal stability over a wide pH range and under high salt concentrations, which contrasts with the limited colloidal stability provided by DHLA alone. Functionalization of the PEG termini enabled one to have easy access to the QD surface and construct a variety of stable QD-biomolecules conjugates. A series of DHLA-based compact ligands with zwitterionic character has also been explored to develop compact sized QDs without sacrificing the colloidal stability. Despite their smaller sizes than the PEG analogs, the QDs coated with the zwitterionic ligands still have excellent colloidal stability and minimize nonspecific interactions in biological environments. Recent studies of thiol-based multidentate ligands and ligand exchange methods further improved the colloidal stability and fluorescence quantum yields.

AB Mg-Ti alloys are attractive for structural applications because of low density and improved corrosion resistance by selective oxidation including hydrogen storage and switchable mirror applications. Titanium has a melting point (1670 degrees C) that greatly exceeds the boiling point of magnesium (1090 degrees C) and therefore, alloying of Mg and Ti by conventional methods is extremely difficult. Secondly, the solubility of Ti in liquid Mg is very low and it is difficult to extend solubility by rapid solidification. Physical vapor deposition by electron beam deposition and magnetron co-sputtering has been used to extend the solubility of Ti in Mg. Mechanical alloying and anvil-cell processing at extreme temperatures and pressures have also used to enforce alloying of Mg with Ti. The present paper deals with the consolidation of blended magnesium-titanium powders by microwave heating, an approach that appears highly cost effective.

We have synthesized optical quality Lu2O3 nanopowders doped with concentrations of 0.1, 1.0, 2.0, and 5% Ho3+. The powders were synthesized by a co-precipitation method beginning with nitrates of holmium and lutetium. The nanopowders were hot pressed into optical quality ceramic discs. The optical transmission of the ceramic discs is excellent, nearly approaching the theoretical limit. The optical, spectral and morphological properties as well as the lasing performance from highly transparent ceramics are presented.

AB Simulations are conducted with a cloud-resolving numerical model to examine the transformation of a weak incipient mid-level cyclonic vortex into a tropical cyclone. Results demonstrate that two distinct pathways are possible and that development along a particular pathway is sensitive to model physics and initial conditions. One pathway involves a steady increase of the surface winds to tropical cyclone strength as the radius of maximum winds gradually decreases. A notable feature of this evolution is the creation of small-scale lower tropospheric cyclonic vorticity anomalies by deep convective towers and subsequent merger and convergence by the low-level secondary circulation. The second pathway also begins with a strengthening low-level circulation, but eventually a significantly stronger mid-level circulation develops. Cyclogenesis occurs subsequently when a small-scale surface concentrated vortex forms abruptly near the center of the larger-scale circulation. The small-scale vortex is warm core throughout the troposphere and results in a fall in local surface pressure of a few millibars. It usually develops rapidly, undergoing a modest growth to form a small tropical cyclone. Many of the simulated systems approach or reach tropical cyclone strength prior to development of a prominent mid-level vortex so that the subsequent formation of a strong small-scale surface concentrated vortex in these cases could be considered intensification rather than genesis. Experiments are performed to investigate the dependence on the inclusion of the ice phase, radiation, the size and strength of the incipient mid-level vortex, the amount of moisture present in the initial vortex, and the sea surface temperature. Notably, as the sea surface temperature is raised, the likelihood of development along the second pathway is in-creased. This appears to be related to an increased production of ice. The sensitivity of the pathway taken to model physics and initial conditions revealed by these experiments raise the possibility that the solution to this initial value problem is near a bifurcation point. Future improvements to model parameterizations and more accurate observations of the transformation of disturbances to tropical cyclones should clarify the conditions that favor a particular pathway when starting from a mid-level vortex.

AB The electrochemical characteristics of 9-fluorenone have been investigated in various ionic liquids as a means of determining the extent of interaction of representative Lewis acids with this ketone. The ionic liquids studied, with Lewis acids in a particular medium, are : 1-ethyl-3-methylimidazolium tetrafluoroborate (EMI BF4) [BF3 etherate], 1-butyl-1-methylpyrrolidinium trifluoromethanesulfonate (BMPY TfO) [Hf(TfO)(4) and Sc(TfO)(3)], and aluminum chloride : 1-ethyl-3-methylimidazolium chloride (AlCl3 : EMICl) [aluminum chloride]. In EMI BF4 and BMPY TfO, 9-fluorenone undergoes two successive one-electron transfers; however, addition of a Lewis acid produces a new reduction process shifted to a more positive potential. The extent of this shift is taken as an indication of the strength of the Lewis acid interaction with 9-fluorenone. The strongest Lewis acid : 9-fluorenone interaction, judging from the magnitude of the potential shift, is found in the AlCl3 : EMIC ionic liquid, followed by that of Hf(TfO)(4) in BMPY TfO. The interaction of Sc(TfO)(3) with 9-fluorenone in BMPY TfO is considerably less than that of Hf(TfO)(4) In EMI BF4, however, Sc(TfO)(3) interacts quite strongly with 9-fluorenone, indicating that the triflate anion interacts extensively enough with Sc3+ in BMPY TfO to restrict its complexation of 9-fluorenone.

AB We analyse the cloud microphysical response to entrainment mixing in warm cumulus clouds observed from the CIRPAS Twin Otter during the GoMACCS field campaign near Houston, Texas, in summer 2006. Cloud drop size distributions and cloud liquid water contents from the Artium Flight phase-Doppler interferometer in conjunction with meteorological observations are used to investigate the degree to which inhomogeneous versus homogeneous mixing is preferred as a function of height above cloud base, distance from cloud edge and aerosol concentration. Using four complete days of data with 101 cloud penetrations (minimum 300 m in length), we find that inhomogeneous mixing primarily explains liquid water variability in these clouds. Furthermore, we show that there is a tendency for mixing to be more homogeneous towards the cloud top, which we attribute to the combination of increased turbulent kinetic energy and cloud drop size with altitude which together cause the Damkohler number to increase by a factor of between 10 and 30 from cloud base to cloud top. We also find that cloud edges appear to be air from cloud centres that have been diluted solely through inhomogeneous mixing. Theory predicts the potential for aerosol to affect mixing type via changes in drop size over the range of aerosol concentrations experienced (moderately polluted rural sites to highly polluted urban sites). However, the observations, while consistent with this hypothesis, do not show a statistically significant effect of aerosol on mixing type.

AB Recently we suggested a dust-based active debris removal technique to selectively remove small untrackable debris that occupies a very large volume around the Earth. For designing a working system an accurate knowledge of the dynamics of the released dust in orbit is necessary. In this paper we numerically examine the dynamics of non-interacting spherical tungsten dust grains of diameter between 30-60 microns released in a polar low-Earth orbit. We analyze different perturbations due to nonuniform gravity, solar radiation pressure, solar cycles as well as solar and lunar gravity, and dust charging effects, etc., and determine a set of forces adequate to describe the dynamics over the life of the dust in orbit (similar to 12-15 years). With the resulting force model we analyze the orbits of many dust grains to determine the formation and geometry of the ring. We qualitatively examine the effects of the calculated geometry and dynamics of the dust cloud on the efficiency of the Active Debris Removal scheme.

AB The unscented Kalman filter (UKF) is a useful alternative to the extended Kalman filter (EKF) for tracking with nonlinear dynamics models and when the measurements are nonlinear functions of the target state. In this paper, the problem of tracking using monostatic and bistatic measurements is considered. Previous work has demonstrated that the UKF does not always handle measurement nonlinearities in challenging monostatic scenarios better than the EKF, let alone considering more complicated bistatic scenarios. This paper reviews previous work showing that the UKF is one among many numeric integration-based filters. It is demonstrated that a general cubature Kalman filter outperforms the extended Kalman filter for multistatic tracking when cubature points of a sufficiently high order are used. Additionally, cubature-based measurement conversion for track initiation is discussed, and the posterior Cramer-Rao lower bound for basic multistatic tracker assessment is derived.

AB The vast majority of literature published on target tracking ignores the effects of atmospheric refraction. When refraction is considered, the solutions are generally tailored to a simple exponential atmospheric refraction model. This paper discusses how arbitrary refraction models can be incorporated into tracking algorithms. Attention is paid to multistatic tracking problems, where uncorrected refractive effects can worsen track accuracy and consistency in centralized tracking algorithms, and can lead to difficulties in track-to-track association in distributed tracking filters. Monostatic and bistatic track initialization using refraction-corrupted measurements is discussed. The results are demonstrated using an exponential refractive model, though an arbitrary refraction profile can be substituted.

AB This paper describes the methodologies and findings from an industry survey of awareness and utility of Spacecraft Plug-&-Play Avionics (SPA). The survey was conducted via interviews, in-person and teleconference, with spacecraft prime contractors and suppliers. It focuses primarily on AFRL's SPA technology development activities but also explores the broader applicability and utility of Plug-&-Play (PnP) architectures for spacecraft. Interviews include large and small suppliers as well as large and small spacecraft prime contractors. Through these "product marketing" interviews, awareness and attitudes can be assessed, key technical and market barriers can be identified, and opportunities for improvement can be uncovered. Although this effort focuses on a high-level assessment, similar processes can be used to develop business cases and economic models which may be necessary to support investment decisions.

AB Solar power satellites have been envisioned as a means to provide electricity for terrestrial use. The approach entails collection of solar energy in space and its wireless transmission to the earth. This potentially gives the benefit of provision of base load power while avoiding the losses due to the day/night cycle and tropospheric effects that are associated with terrestrial solar power. Proponents have contended that the implementation of such systems could offer energy security, environmental, and technological advantages to those who would undertake their development. Among recent implementations commonly proposed for SSP, the Modular Symmetrical Concentrator and other modular concepts have received considerable attention. Each em ploys an array of modules for performing conversion of concentrated sunlight into microwaves or laser beams for transmission to earth. The research described herein details efforts in the development and testing of photovoltaic arrays, power electronics, microwave conversion electronics, and antennas for 2.45 GHz microwave-based "sandwich" module prototypes. Prototypes were designed, fabricated, and subjected to the challenging conditions inherent in the space environment, including the solar concentration levels in which an array of modules might be required to operate.

AB There are a number of scientific motivations for low frequency radio observations from space. These include the possibility of detecting, and eventually imaging, the spectral line of neutral Hydrogen from the cosmic Dark Ages, before the first stars formed. This is the period between the creation of the cosmic microwave background and the formation of the first stars, massive black holes, and galaxies, a period of large-scale structure formation in the universe. The Hydrogen line from the Dark Ages is redshifted down to frequencies of tens of MHz. In addition, imaging and tracking of emission from solar and interplanetary radio bursts, and detecting electron cyclotron emission from extrasolar gas giant planets, all require observations at and below Earth's ionospheric cutoff. Observations far from Earth can completely eliminate ionospheric absorption and distortion, and greatly reduce terrestrial interference (both natural and human-generated). But efficient antennas at low frequency are physically large. Consequently there has been a lot of work exploring concepts for low mass, wide bandwidth low frequency antennas that can be deployed in space. This paper summarizes recent work on deployable low frequency antennas, including thin film antennas that could be unrolled on the lunar surface and inflatable antennas for both free space and lunar locations.

AB A great need exists for reliable nighttime aerosol products at high spatial and temporal resolution. In this concept demonstration study, using Visible/Infrared Imager/Radiometer Suite (VIIRS) Day/Night Band (DNB) observations on the Suomi National Polar-orbiting Partnership (NPP) satellite, a new method is proposed for retrieving nighttime aerosol optical depth (tau) using the contrast between regions with and without artificial surface lights. Evaluation of the retrieved tau values against daytime AERONET data from before and after the overpass of the VIIRS satellite over the Cape Verde, Grand Forks, and Alta Floresta AERONET stations yields a coefficient of determination (r(2)) of 0.71. This study suggests that the VIIRS DNB has the potential to provide useful nighttime aerosol detection and property retrievals.

AB Reduced edge or "edgeless" detector design offers seamless tileability of sensors for a wide range of applications from particle physics to synchrotron and free election laser (FEL) facilities and medical imaging. Combined with through-silicon-via (TSV) technology, this would allow reduced material trackers for particle physics and an increase in the active area for synchrotron and FEL pixel detector systems.
In order to quantify the performance of different edgeless fabrication methods, 2 edgeless detectors were characterized at the Diamond Light Source using an 11 mu m FWHM 15 keV micro-focused X-ray beam. The devices under test were: a 150 mu m thick silicon active edge pixel sensor fabricated at VTT and bump-bonded to a Medipix2 ROIC; and a 300 mu m thick silicon strip sensor fabricated at CIS with edge reduction performed by SCIPP and the NRL and wire bonded to an ALiBaVa readout system.
Sub-pixel resolution of the 55 mu m active edge pixels was achieved. Further scans showed no drop in charge collection recorded between the centre and edge pixels, with a maximum deviation of 5% in charge collection between scanned edge pixels. Scans across the cleaved and standard guard ring edges of the strip detector also show no reduction in charge collection. These results indicate techniques such as the scribe, cleave and passivate (SCP) and active edge processes offer real potential for reduced edge, tiled sensors for imaging detection applications.

TI Design and fabrication of uniquely shaped thiol-ene microfibers using a
two-stage hydrodynamic focusing design
SO LAB ON A CHIP
LA English

ID NONCIRCULAR CARBON-FIBERS; SILK; FLOW
AB Microfluidic systems have advantages that are just starting to be realized for materials fabrication. In addition to the more common use for fabrication of particles, hydrodynamic focusing has been used to fabricate continuous polymer fibers. We have previously described such a microfluidics system which has the ability to generate fibers with controlled cross-sectional shapes locked in place by in situ photopolymerization. The previous fiber fabrication studies produced relatively simple round or ribbon shapes, demonstrated the use of a variety of polymers, and described the interaction between sheath-core flow-rate ratios used to control the fiber diameter and the impact on possible shapes. These papers documented the fact that no matter what the intended shape, higher flow-rate ratios produced rounder fibers, even in the absence of interfacial tension between the core and sheath fluids. This work describes how to fabricate the next generation of fibers predesigned to have a much more complex geometry, as exemplified by the "double anchor'' shape. Critical to production of the pre-specified fibers with complex features was independent control over both the shape and the size of the fabricated microfibers using a two-stage hydrodynamic focusing system. Design and optimization of the channels was performed using finite element simulations and confocal imaging to characterize each of the two stages theoretically and experimentally. The resulting device design was then used to generate thiol-ene fibers with a unique double anchor shape. Finally, proof-of-principle functional experiments demonstrated the ability of the fibers to transport fluids and to interlock laterally.

AB A series of foreign-object-damage (FOD) tests on ceramic thermal barrier coatings (TBCs) of aeroengine airfoil components were performed to determine their responses to ballistic particle impact. Airfoils coated with electron beam, physical vapor deposition (EB-PVD) TBCs were FOD-tested by 1.6 mm-diameter spherical projectiles of two different materials of borosilicate glass and silicon nitride. A range of impact velocities from 150 to 300 m/s was employed for each of projectile materials. Degree and morphologies of impact damage were quantified and characterized in terms of impact velocity, projectile material, and component service-life. A first-order approximation of impact force was made based on the energy balance principle and the 'contact yield pressure' analysis.

AB Dual, large (52 m(3)), outdoor chambers were used to investigate the effect of aerosol aqueous phase chemistry on the secondary organic aerosol (SOA) yields of the photooxidation products of aromatic hydrocarbons in the coastal environment. Toluene and 1,3,5-trimethylbenzene were photochemically oxidised in the presence and absence of inorganic seeds (sea salt aerosol (SSA) or NaCl) at low NOx conditions. Overall, the presence of SSA, which was shown to contain water even at low relative humidities (RHs), led to higher SOA yields than the presence of NaCl seeds and the seedless condition. The results suggest that SOA yields in the coastal environment will be higher than those produced in terrestrial environment. To study the effect of SOA formation on the chemical composition of SSA, inorganic species were measured using a particle-into-liquid-sampler coupled to an ion chromatograph. The hygroscopic properties of the SSA internally mixed with SOA were analysed using a Fourier-transform infrared spectrometer. The fresh SSA shows a weak phase transition whereas no clear phase transition appeared in the aged SSA. The depletion of Cl- due to the accommodation of nitric acid and carboxylic acids on the surface of SSA coincides with changes in aerosol hygroscopic properties.

AB This paper reports vapor-space condensation heat transfer measurements for R123, R134a, and R245fa for the integral trapezoidal fin, and the Turbo-CII geometries on vertical plates. The data consisted of heat flux and wall temperature difference measurements. Condensation heat transfer measurements on a smooth plate agreed well with both measurements and predictions from the literature. Overall, the heat transfer performance of the three refrigerants on the trapezoidal fin was within approximately 8 kW/m(2) of one another. Similarly, the condensation heat flux for R134a and R245fa on the Turbo-CII was within approximately 18 kW/m(2) of each other, while the heat flux of R123 on the Turbo-CII was between 10 and 80 kW/m2 less than that of R245fa. An existing finned tube condensation model was modified to be expressed in terms of the gradient of the condensate curvature with respect to the length of the liquid vapor interface. Curvature gradients for the two surfaces were developed that, when substituted into the modified model, predicted the present measured driving temperature differences for the trapezoidal fin and the Turbo-CII to within 0.4 and 1.2 K, respectively, for all measurements except for R123 on the Turbo-CII surface. With the aid of the curvature gradients, simple models were developed to predict the performance of the trapezoidal, low-finned tube, and the Turbo-C tube. The heat flux to the low-finned tube and the Turbo-C tube were predicted to within 10% and 15%, respectively, of the measured values from the literature for four different fluids.

ID YBCO COATED CONDUCTOR; FILMS
AB The use of high temperature superconductors (HTS) in applications such as power cables, fault current limiters, and electromagnets, has seen rapid growth in recent years. While HTS exhibit zero dc resistance, appreciable ac losses are observed when the HTS are subject to an applied ac magnetic field. By dividing the HTS films into thin filament arrays and creating periodic metallic cross-overs to allow for flux penetration, the ac loss of the HTS can be significantly reduced. The HTS, YBa2Cu3O7-x (YBCO), films were prepared from the metal organic decomposition of a trifluoroacetate-based (TFA) precursor solution onto buffered substrates, manufactured by AMSC. To deposit the TFA solutions onto the buffered substrates, a new laser direct-write (LDW) technique was developed. LDW is a non-contact, non-lithographic process that relies on the mask-less printing of functional materials, such as metallic inks. The transferred TFA precursor filaments were then decomposed and subsequently characterized. In addition to the deposition of TFA precursors onto buffered substrates, LDW was used to print silver lines for metallic crossovers onto HTS tapes. These results show LDW to be a promising technique for the fabrication and modification of high temperature superconductors.

AB This article describes a theory that uses mental models to integrate deductive, inductive, and probabilistic reasoning. It spells out the main principles of the theory and illustrates them with examples from various domains. It shows how models underlie inductions, explanations, estimates of probabilities, and informal algorithms. In all these cases, a central principle is that the mind represents each sort of possibility in a separate mental model and infers whatever holds in the resulting set of models. Finally, the article reviews what has been accomplished in implementing the theory in a single large-scale computer program, mReasoner.

AB A comparative study of 9-fluorenone electrochemistry in the AlCl3 : 1-ethyl-3-methylimidazolium chloride system has been carried out by addition of the Lewis acids AlCl3 and HfCl4 to fluorenone initially in the neutral melt. It has been found that each Lewis acid is capable of forming a complex with fluorenone, resulting in a positive peak potential shift for the reduction process. Neither these peak potentials, nor the colors of the complexes, are exactly the same, indicating that distinct complexes are formed for HfCl4 and AlCl3. There is some possibility of interaction of HfCl4 with the chloroaluminate melt to form the Lewis acid Al2Cl7-, but this route seems to play a minor role in the present case.

AB Person identification is a fundamental robotic capability for long-term interactions with people. It is important to know with whom the robot is interacting for social reasons, as well as to remember user preferences and interaction histories. There exist, however, a number of different features by which people can be identified. This work describes three alternative, soft biometrics (clothing, complexion, and height) that can be learned in real-time and utilized by a humanoid robot in a social setting for person identification. The use of these biometrics is then evaluated as part of a novel experiment in robotic person identification carried out at Fleet Week, New York City in May, 2012. In this experiment, Octavia employed soft biometrics to discriminate between groups of 3 people. 202 volunteers interacted with Octavia as part of the study, interacting with the robot from multiple locations in a challenging environment.

AB A self-assembled metamaterial exhibiting a positive near-zero index of refraction at visible wavelengths is demonstrated. The metamaterial consists of thiolene-functionalized gold nanospheres self-assembled into macroscopic, crosslinked, monolayers. By measuring the real and imaginary parts of the phase shift of light transmitted through the self-assembled films the effective index of refraction is determined as a function of wavelength. These findings may pave a way to simply and efficiently self-assemble and optically characterize multifunctional, multilayer nanoparticle-ligand metamaterials.

AB The University of Wisconsin Ion Beam Laboratory (UW-IBL) has recently undergone significant infrastructure upgrades to facilitate graduate level research in irradiated materials phenomena and ion beam analysis. A National Electrostatics Corp. (NEC) Torodial Volume Ion Source (TORVIS), the keystone upgrade for the facility, can produce currents of hydrogen ions and helium ions up to similar to 200 mu A and similar to 5 mu A, respectively. Recent upgrades also include RBS analysis packages, end station developments for irradiation of relevant material systems, and the development of an in-house touch screen based graphical user interface for ion beam monitoring. Key research facilitated by these upgrades includes irradiation of nuclear fuels, studies of interfacial phenomena under irradiation, and clustering dynamics of irradiated oxide dispersion strengthened steels. The UW-IBL has also partnered with the Advanced Test Reactor National Scientific User Facility (ATR-NSUF) to provide access to the irradiation facilities housed at the UW-IBL as well as access to post irradiation facilities housed at the UW Characterization Laboratory for Irradiated Materials (CLIM) and other ATR-NSUF partner facilities. Partnering allows for rapid turnaround from proposed research to finalized results through the ATR-NSUF rapid turnaround proposal system. An overview of the UW-IBL including CLIM and relevant research is summarized.

ID SYSTEMS
AB Nuclear data important for the design and development of the next generation of light-water reactors and future fast reactors include neutron elastic and inelastic scattering cross sections on important structural materials, such as Fe, and on coolant materials, such as Na. These reaction probabilities are needed since neutron reactions impact fuel performance during irradiations and the overall efficiency of reactors. While neutron scattering cross sections from these materials are available for certain incident neutron energies, the fast neutron region, particularly above 2 MeV, has large gaps for which no measurements exist, or the existing uncertainties are large. Measurements have been made at the University of Kentucky Accelerator Laboratory to measure neutron scattering cross sections on both Fe and Na in the region where these gaps occur and to reduce the uncertainties on scattering from the ground state and first excited state of these nuclei. Results from measurements on Fe at incident neutron energies between 2 and 4 MeV will be presented and comparisons will be made to model calculations available from data evaluators.

AB Servicemembers with combat-related limb loss often require substantial rehabilitative care. The prevalence of traumatic brain injury (TBI), which may impair cognitive and functional abilities, among servicemembers has increased. The primary objectives of this study were to determine the frequency of TBI among servicemembers with traumatic amputation and examine whether TBI status was associated with discharge to civilian status and medical and rehabilitative service use postamputation. U.S. servicemembers who had a combat-related amputation while deployed in Iraq or Afghanistan between 2001 and 2006 were followed for 2 yr postamputation. Data collected includes injury mechanism; postinjury complications; Injury Severity Score (ISS); and follow-up data, including military service discharge status and number of medical, physical, occupational therapy, and prosthetic-related visits. Of the 546 servicemembers with combat-related amputations, 127 (23.3%) had a TBI diagnosis. After adjusting for ISS and amputation location, those with TBI had a significantly greater mean number of medical and rehabilitative outpatient and inpatient visits combined (p < 0.01). Those with TBI were also at greater odds of developing certain postinjury complications. We recommend that providers treating servicemembers with limb loss should assess for TBI because those who sustained TBI required increased medical and rehabilitative care.

AB The high rate capability and reversibility of lithium iron phosphate battery cathodes is attributed to the highly reversible transition between its LiFePO4 and FePO4 phases. Conflicting models exist for the phase transition mechanism, such as the shrinking or expanding core models, surface reaction limited model, and the single-phase kinetic model. A literature review suggests that the subscribed theories depend upon the experimental methods and also the geometry and size of the LiFePO4 particles. We study the electronic structure and disorder during the two-phase transition of commercial oval-shaped LiFePO4 particles using in situ XAS (X-ray absorption spectroscopy) with the Delta mu XANES (X-ray absorption neat edge structure) difference technique along with traditional EXAFS (extended X-ray absorption fine structure) to track the Debye-Waller (DW) factor. The Delta mu XANES magnitude, vertical bar Delta mu vertical bar, tracks changes in the electronic structure which does not follow a synchronous path with lithium content. The magnitude of the DW shows the degree of structural disorder reaches a maximum near the middle of the charge/discharge cycle. The combined vertical bar Delta mu vertical bar and EXAFS results suggests the LiFePO4/FePO4 transition occurs through a "collective mosaic" or an unrelaxed "sequential" single-phase kinetic model.

AB Mullite is considered a promising candidate for future structural applications such as ceramic recuperators in turbo propelled engines, due to its highly favourable properties at high temperatures. In order for it to be viable for structural applications its relatively weak fracture toughness needs to be improved. A reliable way of improving fracture toughness in a range of materials is to tailor the microstructure to contain elongated grains capable of bridging cracks. In this paper, the tailoring of mullite microstructures using a range of processing methods are reported: reactive sintering of mixtures of alumina and silica, sol-gel synthesis of mullite and the use of sol-gel derived additives to enhance the sintering of commercial mullite powders. The difference in morphologies produced as well as the influence on indentation fracture toughness is described.

AB Foreign object damage (FOD) aspects of an oxide/oxide ceramic matrix composite (CMC) were determined using spherical steel ball projectiles in impact velocity ranging from 100 to 340 m/s. The oxide/oxide CMC test targets were ballistically impacted at a normal incidence angle while sustained in cantilever support. Surface and subsurface impact damages were in the forms of craters, fiber breakage, delamination, cone cracks, and backside protrusion, typically observed in many CMCs in their ballistic impact responses. Qualitative impact damage was also assessed through post-impact residual strength measurements. Compared to two other types of target supports (full and partial supports), the cantilever support configuration resulted in the greatest impact damage of all the three. The impact damage in cantilever support is believed to have been involved both by quasi-static impression and by stress wave interactions, while the impact damage in partial and full supports was involved mainly by quasi-static dynamic impression.

AB According to recent studies, internal mixing of black carbon (BC) with other aerosol materials in the atmosphere alters its aggregate shape, absorption of solar radiation, and radiative forcing. These mixing state effects are not yet fully understood. In this study, we characterize the morphology and mixing state of bare BC and BC internally mixed with sodium chloride (NaCl) using electron microscopy and examine the sensitivity of optical properties to BC mixing state and aggregate morphology using a discrete dipole approximation model (DDSCAT). DDSCAT is flexible in simulating the geometry and refractive index of particle aggregates. DDSCAT predicts a higher mass absorption coefficient (MAC), lower single scattering albedo (SSA), and higher absorption Angstrom exponent (AAE) for bare BC aggregates that are lacy rather than compact. Predicted values of SSA at 550 nm range between 0.16 and 0.27 for lacy and compact aggregates, respectively, in agreement with reported experimental values of 0.25 +/- 0.05. The variation in absorption with wavelength does not adhere precisely to a power law relationship over the 200 to 1000 nm range. Consequently, AAE values depend on the wavelength region over which they are computed. The MAC of BC (averaged over the 200-1000 nm range) is amplified when internally mixed with NaCl (100-300 nm in radius) by factors ranging from 1.0 for lacy BC aggregates partially immersed in NaCl to 2.2 for compact BC aggregates fully immersed in NaCl. The SSA of BC internally mixed with NaCl is higher than for bare BC and increases with the embedding in the NaCl. Internally mixed BC SSA values decrease in the 200-400 nm wavelength range, a feature also common to the optical properties of dust and organics. Linear polarization features are also predicted in DDSCAT and are dependent on particle size and morphology.
This study shows that DDSCAT predicts complex morphology and mixing state dependent aerosol optical properties that have been reported previously and are relevant to radiative transfer, climate modeling, and interpretation of remote sensing measurements.

AB This paper reports on the influence of deposition temperature on the structure, composition, and electrical properties of TiO2 thin films deposited on n-type silicon (100) by plasma-assisted atomic layer deposition (PA-ALD). TiO2 layers similar to 20 nm thick, deposited at temperatures ranging from 100 to 300 degrees C, were investigated. Samples deposited at 200 degrees C and 250 degrees C had the most uniform coverage as determined by atomic force microscopy. The average carbon concentration throughout the oxide layer and at the TiO2/Si interface was lowest at 200 degrees C. Metal oxide semiconductor capacitors (MOSCAPs) were fabricated, and profiled by capacitance-voltage techniques. The sample prepared at 200 degrees C had negligible hysteresis (from a capacitance-voltage plot) and the lowest interface trap density (as extracted using the conductance method). Current-voltage measurements were carried out with top-to-bottom structures. At -2 V gate bias voltage, the smallest leakage current was 1.22 x 10(-5) A/cm(2) for the 100 degrees C deposited sample.

AB Special districts now constitute about 42% of all U.S. jurisdictions, yet little is known about them. Some critics are concerned that special districts and their staffs have insufficient community commitment. This study, based on a national survey of senior managers in large special districts, examines activities and programs of special district managers that foster community building and engagement, including correlates of these. Study results reveal that special districts are committed to their communities and several strategies and conditions are associated with increased community commitment, such as jobs that focus on community interactions, service type, and ethics management, as well as, to a lesser extent, graduate degree qualifications and charters that specify the role of managers in promoting the public interest and in relation to the board.

AB An N-functionalized strategy, including N-amination and N-trinitroethylamination, was utilized for the synthesis of nitroimidazole-based energetic materials, giving rise to a new family of highly insensitive N-aminonitroimidazoles and oxygen-rich N-trinitroethylaminonitroimidazoles with good to excellent properties. These new energetic materials were fully characterized by IR, H-1, and C-13 NMR, elemental analysis, and some high performance compounds were further confirmed by N-15 NMR (4a, 4d, 6a, 6b, and 6d), as well as single crystal X-ray diffraction (6a and 6b). N-Functionalization of nitroimidazoles not only gives rise to the N-aminonitroimidazoles as impact insensitive and thermally stable materials (IS > 40 J; T-d: 144-308 degrees C), but also provides a series of N-trinitroethylaminoimidazoles, which have favorable densities (1.75-1.84 g cm(-3)), good detonation properties (P: 27.6-35.9 GPa; v(D): 7815-8659 m s(-1)), and moderate thermal stabilities (136-172 degrees C). These properties are better than some known energetic compounds, such as TNT (P: 19.5 GPa; v(D): 6881 m s(-1)) and TATB (P: 31.2 GPa; v(D): 8114 m s(-1)), and are comparable to RDX (P: 35.0 GPa; v(D): 8762 m s(-1)).

AB The purpose of this study was to describe career performance outcomes after combat blast injury and to examine the relationship between the injury severity and type of military discharge. A retrospective cohort study of 4,255 male service-members injured in a combat blast as a part of Operation Iraqi Freedom was completed. In the total sample, 37.8% experienced a normal discharge and 8.3% had an early discharge. Of the 2,229 members who had a discharge code, 29.8% experienced a disability discharge. Both early attrition and disability discharge proportions were higher in those with posttraumatic stress disorder (PTSD) than in those without PTSD. There was a significant interaction between PTSD and injury severity in the discharge disability outcome. In those without PTSD, there was a dose-response relationship between injury severity and disability discharge. In those with PTSD, injury severity predicted disability discharge. The relationship between injury severity and disability discharge was less striking in service-members with PTSD than without PTSD. The effect of PTSD and injury severity on career performance outcomes after blast injuries should be factored into outcome planning.

AB Understanding the thermal stability of major reaction products, Li2O2 (space group P6(3)/mmc) and Li2O (space group Fm (3) over barm) is critical to improve the safety characteristics of Li-air batteries. The changes in the crystal structure and surface chemistry of Li2O2 and Li2O were examined as a function of temperature via in situ X-ray diffraction (XRD) and in situ X-ray photoelectron spectroscopy (XPS). Significant decreases in the lattice parameters and the c/a ratio of Li2O2 were found at 280 degrees C and higher. These structural changes can be attributed to the transformation of Li2O2 to Li2O2-delta, which is supported by density functional theory calculations. Upon further heating to 700 degrees C, a lithium-deficient Li2-delta O phase appeared at 300 degrees C and gradually became stoichiometric upon further heating to similar to 550 degrees C. XPS measurements of Li2O2 revealed that Li2O appeared on the surface starting at 250 degrees C, which is in agreement with the onset temperature of phase transformation as detected by XRD. In addition, the growth of Li2CO3 on the surface was found at 250 degrees C, which can be attributed to chemical reactions between Li2O2/Li2O and carbon-containing species (e.g. hydrocarbons) present in the XPS chamber. This finding highlights the challenges of developing stable carbon-based oxygen electrode for Li-air batteries. (C) 2013 The Electrochemical Society. All rights reserved.

AB Cloud droplet formation depends on the condensation of water vapor on ambient aerosols, the rate of which is strongly affected by the condensation (or mass accommodation) coefficient, alpha(c). Estimates of alpha(c) for droplet growth from activation of ambient particles vary considerably and represent a critical source of uncertainty in estimates of global cloud droplet distributions and the aerosol indirect forcing of climate. An analysis of ten globally relevant data sets of cloud condensation nuclei is used to constrain alpha(c), and find that rapid activation kinetics (alpha(c) > 0.1) is uniformly prevalent. This means that uncertainty in water vapor accommodation on droplets is less than previously thought and resolves a long-standing issue in cloud physics.

AB The tricyanate esters of the natural product resveratrol (1) and dihydroresveratrol (2) were synthesized and subjected to thermal curing which gave polycyanurate network polymers which exhibited glass transition temperatures of >340 degrees C and 334 degrees C, respectively. Thermal decomposition temperatures of 412 degrees C and 403 degrees C for polycyanurates of 1 and 2, respectively, were typical of this class. However, char yields (600 degrees C) of 71% and 66% for 1 and 2, respectively, were more than double that from the polycyanurate of bisphenol A dicyanate (25%).

ID ROOM-TEMPERATURE
AB We discuss two distinct approaches to realizing distributed-feedback (DFB) interband cascade lasers (ICLs) for emission in the mid-IR. In the top-grating approach, the first-order gratings are produced by patterning high-index germanium layers on top of narrow ridges with relatively thin top claddings. One 7-mu m-wide device emitting at lambda = 3.8 mu m generated over 27 mW of cw single-mode output at 40 degrees C, with a side-mode-suppression ratio >30 dB, while at 80 degrees C it still emitted >1 mW. At 20 mu C, a second device lased in a single spectral mode with <100 mW of drive power. The tuning range was 21.5 nm with temperature and 10 nm with current. The corrugated-sidewall approach relies on a fourth-order grating defined by optical lithography and etched into the sidewalls of the laser ridge. For a 13-mu m-wide ICL ridge emitting at lambda = 3.6 mu m, the maximum power at T = 25 degrees C was 55 mW, and at 40 degrees C the device still produced 11 mW. We compare the physical requirements and performance characteristics for the two DFB classes and conclude that top-grating DFBs generally exhibit greater stability and reproducibility, although the efficiency is reduced by extra loss induced by modal overlap with the top metallization.

AB A previous effort demonstrated the utility of porphyrin functionalized organosilicate sorbents in the removal of phosgene. The current study sought to characterize the spectrophotometric response of the sorbents during their application to determine the potential for dual use in both removal of phosgene and reporting on phosgene exposure. The effort is intended as a first step toward using the materials for self-reporting or residual life indication. An ethane bridged silica was functionalized using deuteroporphyrin IX 2,4 bis- ethylene glycol. Several metalloporphyrin variants were generated based on this porphyrin functionalized sorbent, and fluorescence characteristics were evaluated in the prior to and following exposure to phosgene. Reflectance characteristics and changes upon target exposure were also evaluated. Cu, Mg, and Zn sorbents showed the most significant changes upon exposure to phosgene. The reflectance characteristics of these sorbents were evaluated across a range of loading levels for sorbent columns to the point of complete target breakthrough. The results indicate the possibility for reflectance or visual inspection based end-of-life indication for these sorbents. Published by Elsevier B.V.

AB The electrical characteristics of oxygen functionalized epitaxial graphene and Ti/Au metal contact interfaces were systematically investigated as a function of temperature. As the temperature was increased from 300 K to 673 K, the contact resistance and the sheet resistance decreased by 75% and 33%, respectively. The resistance of oxygen functionalized graphene vs temperature exhibited Arrhenius type behavior with activation energy of 38 meV. The results showed no hysteresis effects in resistance measurements over the temperatures studied here, suggesting the contact interfaces remain stable at high temperatures.

AB The multiple-zone junction termination extension (MJTE) is a widely used SiC edge termination technique that reduces sensitivity to implantation dose variations. It is typically implemented in multiple lithography and implantation events. To reduce process complexity, cycle time, and cost, a single photolithography/implantation (P/I) MJTE technique was developed and diodes with 3-zone and 120-zone JTEs were fabricated on the same wafer. Here, the process tolerance of the single (P/I) MJTE technique is evaluated by performing CCD monitored blocking voltage measurements on diodes from the same wafer with the 3-zone and 120-zone single (P/I) JTE. The 3-zone JTE diodes exhibited catastrophic localized avalanches at the interface between the 2nd and 3rd zones due to abrupt zone transitions. Diodes with the smooth transitioning 120-zone JTE exhibited no CCD detectable avalanches in their JTE regions up to the testing limit of 12 kV. Under thick dielectric (deposited for on-wafer diode interconnection), diodes with the single P/I 3-zone JTE failed due to significant loss of high-voltage capability, while their 120-zone JTE diode counterparts were minimally affected. Overall, the single (P/I) 120-zone JTE provides a process-tolerant and robust single P/I edge termination at no additional fabrication labor.

ID MULTISENSOR DATA FUSION
AB It is well known that fusion classifiers for physiological signal classification with diverse components (classifiers or data sets) outperform those with less diverse components. Determining component diversity, therefore, is of the utmost importance in the design of fusion classifiers that are often employed in clinical diagnostic and numerous other pattern recognition problems. In this article, a new pairwise diversity-based ranking strategy is introduced to select a subset of ensemble components, which when combined will be more diverse than any other component subset of the same size. The strategy is unified in the sense that the components can be classifiers or data sets. Moreover, the classifiers and data sets can be polychotomous. Classifier-fusion and data-fusion systems are formulated based on the diversity-based selection strategy, and the application of the two fusion strategies are demonstrated through the classification of multichannel event-related potentials. It is observed that for both classifier and data fusion, the classification accuracy tends to increase/decrease when the diversity of the component ensemble increases/decreases. For the four sets of 14-channel event-related potentials considered, it is shown that data fusion outperforms classifier fusion. Furthermore, it is demonstrated that the combination of data components that yield the best performance, in a relative sense, can be determined through the diversity-based selection strategy.

AB Moderate Resolution Imaging Spectroradiometer (MODIS) Deep Blue (DB) collection 5.1 (c5.1) aerosol optical depth (AOD) data were analyzed and evaluated for the first time from an independent research group using eight years of Terra (2000-2007) and Aqua (2002-2009). Uncertainties in the DB AOD were identified and studied, and our results show that the performance of DB c5.1 is strongly dependent on surface albedo and aerosol microphysics. Using data with only "very good" quality assurance, the root-mean-square error (RMSE) of the DB Terra (Aqua) AOD is 0.24 (0.19) when validated against AERONET. Expanding upon the uncertainty analysis, the potential of applying the DB products for aerosol assimilation was explored. Empirical corrections and quality assurance procedures were developed for North Africa and the Arabian Peninsula to create a data assimilation (DA)-quality DB product. After applying those procedures, the RMSE is reduced by 18.1% (18.2 %) for Terra (Aqua) DB data. Prognostic error models of 0.069 + 0.175 x AOD(Terra_DB) with no noise floor and 0.048 + 0.182 x AOD(Aqua_DB) with a noise floor of 0.104 were found for DA-quality Terra and Aqua DB data, respectively. These procedures were also applied to two months of DB collection 6 (c6) AOD data, and reductions in RMSE were found, indicating that the algorithms developed for c5.1 data are applicable to c6 data to some extent.

AB We observe changes in the molecular conductivity of individual oligophenylene-vinylene (OPV) molecules due to interactions with small aromatic molecules. Fluorescence experiments were correlated with scanning tunneling microscopy measurements in order to determine the origin of the observed effect. Both nitrobenzene and 1,4-dinitrobenzene decreased fluorescence intensity and molecular conductivity, while toluene had no effect. The observed changes in the fluorescence and conduction of OPV correlate well with the electron withdrawing ability of the interacting aromatic molecules. These results demonstrate the potential usefulness of OPV as a sensor for aromatic compounds containing electron withdrawing groups.

AB The Naval Undersea Warfare Center has funded a project to investigate the accuracy of various bolt models used to represent actual shipboard bolted connections within an analytical shock survivability assessment. The ultimate goal within this project is to develop finite element bolt representations that are not only computationally efficient, but also accurate. A significant task within this effort involved the development of highly detailed finite element models of bolted connections under various load configurations. Accordingly, high-resolution bolt models were developed and incorporated into simulations of four bolted connection test arrangements: static shear, static tension, dynamic shear, and dynamic tension. These simulation results are validated against experimental data from physical testing of each configuration. Future research will focus on exploring simplified finite element bolt representations and comparing these against the high-resolution results.

AB Sources offer a convenient way to prescribe a size distribution in space. For each newly created mesh point, the mesh generator queries the local size distribution, either to create a new point or element, depending on the underlying mesh generation method, to smooth the mesh, or to get a local relevant length scale. Sources may have different shapes such as points, edges, triangles, or boxes. They provide the size distribution given some user defined parameters and the distance of a point location to the source. Traditionally, the source strength is considered as constant. In this work, extensions to linear sources in space are proposed. It is shown that in the case of curvature refined mesh generation, substantial savings may occur due to the much better approximation of the curvature variation for a simple modification of traditional sources. Even though curvature refinement is the main application of this work, improvements through linear sources are relevant to other contexts such as user defined sources. The technique is very general as it deals with a fundamental aspect of mesh generation and can be easily incorporated into an existing mesh generator with traditional sources. Thorough details of source approximations and source filtering are provided. Relations with lower envelopes are highlighted. Practical examples illustrate the accuracy and efficiency of the method.

AB Dissolved CO2 radiocarbon and stable carbon isotope ratios were measured in groundwater from a fuel contaminated site at the North Island Naval Air Station in San Diego, CA (USA). A background groundwater sampling well and 16 wells in the underground fuel contamination zone were evaluated. For each sample, a two end-member isotopic mixing model was used to determine the fraction of CO2 derived from fossil fuel. The CO2 fraction from fossil sources ranged from 8 to 93% at the fuel contaminated site, while stable carbon isotope values ranged from -14 to +5 parts per thousand(VPDB). Wells associated with highest historical and contemporary fuel contamination showed the highest fraction of CO2 derived from petroleum (fossil) sources. Stable carbon isotope ratios indicated sub-regions on-site with recycled CO2 (delta(CO2)-C-13 as high as +5 parts per thousand(VPDB)) - most likely resulting from methanogenesis. Ancillary measurements (pH and cations) were used to determine that no fossil CaCO3, for instance limestone, biased the analytical conclusions. Radiocarbon analysis is verified as a viable and definitive technique for confirming fossil hydrocarbon conversion to CO2 (complete oxidation) at hydrocarbon-contaminated groundwater sites. The technique should also be very useful for assessing the efficacy of engineered remediation efforts and by using CO2 production rates, contaminant mass conversion over time and per unit volume.

AB The military's need to reduce both fuel and battery resupply is a real-time requirement for increasing combat effectiveness and decreasing vulnerability. Mobile photovoltaics (PV) is a technology that can address these needs by leveraging emerging, flexible space PV technology. In this project, the development and production of a semirigid, lightweight, efficient solar blanket with the ability to mount on, or stow in, a backpack and recharge a high-capacity rechargeable lithium-ion battery was undertaken. The 19% efficient blanket consists of a 10 x 3 solar array of 20 cm(2) and single-junction epitaxial lift-off solar cells, which have an efficiency of similar to 22% under AM1.5G illumination. A power-conditioning module was also developed to interface the solar panel to the battery. Thirteen systems were outfitted during a Limited Objective Experiment-1 in February 2012, and based on the results, a second version of the system is in development.

AB The ensemble adjustment Kalman filter (EAKF) is used to estimate the erodibility fraction parameter field in a coupled meteorology and dust aerosol model (Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS)) over the Sahara desert. Erodibility is often employed as the key parameter to map dust source. It is used along with surface winds (or surface wind stress) to calculate dust emissions. Using the Saharan desert as a test bed, a perfect model Observation System Simulation Experiments (OSSEs) with 40 ensemble members, and observations of aerosol optical depth (AOD), the EAKF is shown to recover correct values of erodibility at about 80% of the points in the domain. It is found that dust advected from upstream grid points acts as noise and complicates erodibility estimation. It is also found that the rate of convergence is significantly impacted by the structure of the initial distribution of erodibility estimates; isotropic initial distributions exhibit slow convergence, while initial distributions with geographically localized structure converge more quickly. Experiments using observations of Deep Blue AOD retrievals from the MODIS satellite sensor result in erodibility estimates that are considerably lower than the values used operationally. Verification shows that the use of the tuned erodibility field results in better predictions of AOD over the west Sahara and the Arabian Peninsula.

AB Time-dependent variational data assimilation allows the possibility of extracting wind information from observations of ozone or other trace gases. Since trace gas observations are not available at sufficient resolution for deriving feature-track winds, they must be combined with model background information to produce an analysis. If done with time-dependent variational assimilation, wind information may be extracted via the adjoint of the linearized tracer continuity equation. This paper presents idealized experiments that illustrate the mechanics of tracer-wind extraction and demonstrate some of the limitations of this procedure. We first examine tracer-wind extraction using a simple one-dimensional advection equation. The analytic solution for a single trace gas observation is discussed along with numerical solutions for multiple observations. The limitations of tracer-wind extraction are then explored using highly idealized ozone experiments performed with a development version of the Navy Global Environmental Model (NAVGEM) in which globally distributed hourly stratospheric ozone profiles are assimilated in a single 6 h update cycle in January 2009. Starting with perfect background ozone conditions, but imperfect dynamical conditions, ozone errors develop over the 6 h background window. Wind increments are introduced in the analysis in order to reduce the differences between background ozone and ozone observations. For "perfect" observations (unbiased and no random error), this results in root-mean-square (RMS) vector wind error reductions of up to similar to 4 m s(-1) in the winter hemisphere and tropics. Wind extraction is more difficult in the summer hemisphere due to weak ozone gradients and smaller background wind errors. The limitations of wind extraction are also explored for observations with imposed random errors and for limited sampling patterns. As expected, the amount of wind information extracted degrades as observation errors or data voids increase. In the case of poorly specified observation error covariances, assimilation of ozone data with imposed errors may result in increased RMS wind error, since the assimilation is constrained too tightly to the noisy observations.

AB A model is presented for analysis of multivariate binary data with spatio-temporal dependencies, and applied to congressional roll call data from the United States House of Representatives and Senate. The model considers each legislators constituency (location), the congressional session (time) of each vote, and the details (text) of each piece of legislation. The model can predict votes of new legislation from only text, while imposing smooth temporal evolution of legislator latent features, and correlation of legislators with adjacent constituencies. Additionally, the model estimates the number of latent dimensions required to represent the data. A Gibbs sampler is developed for posterior inference. The model is demonstrated as an exploratory tool of legislation and it performs well in quantitative comparisons to a traditional ideal-point model.

AB In the present study, we have successfully combined the biocompatible properties of chitin with the high electrical conductivity of carbon nanotubes (CNTs) by mixing them using an imidazolium-based ionic liquid as a common solvent/dispersion medium. The resulting nanocomposites demonstrated uniform distribution of CNTs, as shown by scanning electron microscopy (SEM) and optical microscopy. Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction confirmed the a-crystal structure of chitin in the regenerated chitin nanocomposite scaffolds. Increased CNT concentration in the chitin matrix resulted in higher conductivity of the scaffolds. Human mesenchymal stem cells adhered to, and proliferated on, chitin-CNT nanocomposites with different ratios. Cell growth in the first 3 days was similar on all composites at a range of (0.01 to 0.07) weight fraction of CNT. However, composites at a 0.1 weight fraction of CNTs showed reduced cell attachment. There was a significant increase in cell proliferation using 0.07 weight fraction CNT composites, suggesting a stem cell enhancing function for CNTs at this concentration. In conclusion, the ionic liquid allowed the uniform dispersion of CNTs and dissolution of chitin to create a biocompatible, electrically conducting scaffold permissive for mesenchymal stem cell function. This method will enable the fabrication of chitin-based advanced multifunctional biocompatible scaffolds where electrical conduction is critical for tissue function.

AB This study evaluates the ability of the Hawaii Regional Navy Coastal Ocean Model to accurately predict the depth of the surface mixed layer in the lee of the Hawaiian Islands. Accurately modeling the depth of the surface mixed layer in this complex wake island environment is important to naval operations because the area hosts numerous training exercises. The simulated data were compared to CTD data collected from sea gliders, and tests for correlation were conducted. For mixed layer depths that did show correlation, match-paired t tests were used to determine the significance of the correlations. It was determined that the Hawaii Regional Navy Coastal Ocean Model has difficulty accurately predicting the depth of the surface mixed layer. It was also determined that the model has difficulty with unusual oceanographic features such as mode water eddies. These features are too uncommon and short-lived to be depicted in the climatology data. The climatology data are a major component of the synthetic profiles that the model generates, and these profiles tend to smooth out the unusual subsurface isothermal layer.

AB This article presents a comprehensive experimental and numerical study to investigate the effects of strain rate and temperature on flow stress and ductile failure strain of three aluminum alloys. The test matrix includes smooth and notched round tensile specimens tested at room temperature (24 degrees C) and two elevated temperatures (66 degrees C and 149 degrees C), and under different strain rates. For 5083-H116, three loading rates are considered at 24 degrees C and it is found that the flow stress and failure strain are lowest at the intermediate strain rate. At high strain rate, the flow stresses of 5083-H116 and 6082-T6 are higher than the quasi-static loading while the flow stress of the 5183 weld metal remains unchanged; the ductility of the 5XXX alloys shows a significant increase compared to the quasi-static loading while the ductility of 6082-T6 does not change much. The study indicates that the Johnson-Cook plasticity and fracture models can be used to describe the temperature dependencies of the flow stress and the failure strain for 6082-T6 but not the 5XXX alloys. At 66 degrees C the 5XXX alloys do not display temperature softening compared to 24 degrees C while their ductility is reduced. As temperature is elevated to 149 degrees C, the flow stress of the 5XXX alloys decreases while the ductility increases. The unconventional behavior of the 5XXX alloys in certain temperature and strain rate ranges has been attributed to the dynamic strain aging effect. The study also suggests that the dependency of the failure strain on stress triaxiality can be described by the Johnson-Cook fracture model for all three materials under quasi-static loading at room temperature and the model parameters are calibrated using an inverse method combining experimental results with finite element analysis.

DE Model Based Systems Engineering; integration; qualification; system

AB Many system developments fail at the integration and qualification (I&Q) phases in the development and acquisition cycle. How can we, as Systems Engineers (SE), navigate the uncertainty and risk of system development to ensure I&Q success? One solution is applying significant influence of the system integrator (SI) member of the SE team at the very beginning of system design. If this is a solution, then what processes, methods, and practices can the SI apply in the overall SE process? Can the emerging Model-Based Systems Engineering (MBSE) methods and tools be leveraged by the SI? This paper discusses a Model Based System Integration (MBSI) approach that applies essential MBSE methods and tools to the unique goals of the SI. While MBSE is supportive of the entire SE process, it tends to be optimized for the design-side of the SE process and not necessarily for I&Q goals and objectives. MBSI highlights how MBSE tools and methods can be extended to benefit the SI. Lessons-learned from several SE graduate school projects applying these MBSI methods are provided to demonstrate the efficacy of the MBSI approach. (C) 2013 The Author. Published by Elsevier B. V.

The Graduate Reference Curriculum for Systems Engineering (GRCSE) provides guidelines for graduate program degrees in systems engineering. GRCSE establishes a baseline set of entrance expectations, objectives, outcomes and content for any graduate degree in systems engineering. GRCSE recognizes that each university needs to meet the needs of their constituents, and for this purpose, GRCSE only defines 50% of the program content, and leaves the other 50% to be defined by individual universities to satisfy the needs of their stakeholder.

AB Results from an interannually forced, 0.08 degrees eddy-resolving simulation based on the Hybrid Coordinate Ocean Model, in conjunction with a small but well-determined transport database, are used to investigate the currents and transports associated with the Atlantic meridional overturning circulation (AMOC) in the subpolar North Atlantic (SPNA). The model results yield a consistent warming in the western SPNA since the early 1990s, along with mean transports similar to those observed for the trans-basin AMOC across the World Ocean Circulation Experiment hydrographic section AR19 (16.4 Sv) and boundary currents at the exit of the Labrador Sea near 53 degrees N (39.0 Sv) and east of the Grand Banks near 43 degrees N (15.9 Sv). Over a 34 year integration, the model-determined AMOC across the AR19 section and the western boundary current near 53 degrees N both exhibit no systematic trend but some long-term (interannual and longer) variabilities, including a decadal transport variation of 3-4 Sv from relatively high in the 1990s to low in the 2000s. The decadal variability of the model boundary current transport near 53 degrees N lags the observed winter time North Atlantic Oscillation index by about 2 years and leads the model AMOC across the AR19 section by about 1 year. The model results also show that the long-term variabilities are low compared to those on shorter time scales. Thus, rapid sampling of the current over long time intervals is required to filter out high-frequency variabilities in order to determine the lower frequency variabilities of interest.

AB Stimulated electromagnetic emissions (SEEs) may provide important diagnostic information about space plasma composition, energetics, and dynamics during active experiments in which ground-based high-powered radio waves are transmitted into the ionosphere. The nonlinear plasma processes producing this secondary radiation are not well understood particularly for some recent observations where the transmitter (pump) frequency is near the second harmonic of the electron gyrofrequency. New, more comprehensive, experimental observations of spectral features within 1 kHz of the pump wave frequency are reported here to begin more careful comparisons of the experimental observations and a possible theoretical underpinning, which is also provided. The experimental observations typically show two distinct types of secondary radiation spectra, which are (a) discrete narrowband harmonic spectral structures ordered by the ion gyrofrequency and (b) broadband spectral structure with center frequency near 500 Hz and similar spectral bandwidth. A theoretical model is provided that interprets these spectral features as resulting from parametric decay instabilities in which the pump field ultimately decays into high-frequency upper hybrid/electron Bernstein and low-frequency neutralized ion Bernstein and/or obliquely propagating ion acoustic waves at the upper hybrid interaction altitude. Detailed calculations of the threshold level, growth rate, unstable wave number, and frequency bandwidth of the instabilities are provided for comparisons with experimental observations. An assessment of the effect of the critical instability parameters are provided including pump electric field strength, proximity of the pump frequency to the electron gyrofrequency and pump electric field geometry. The model shows quite reasonable agreement with the experimental observations. Further discussions are provided of connections with past observed SEE spectral features and potential new diagnostic information provided by these newly categorized spectra. Citation: Samimi, A., W.

AB We have examined the electrochemical performance and the surface chemistry of quenched and annealed LiNi0.5Mn0.5O2 electrodes as a function of high voltage cutoff via X-ray photoelectron spectroscopy (XPS). After cycling for 20 cycles, the surface regions of quenched and annealed electrodes are significantly enriched in fluorine and lithium relative to pristine electrodes, with the degree of enrichment being greater for the annealed electrodes. Mn and Ni fluorides are observed on the surface of the cycled annealed electrodes while both Mn and Ni oxides and fluorides are observed on the surface of the cycled quenched electrodes. The XPS data indicate that the surface films formed on the annealed electrodes as a result of cycling are thicker than the films formed on the quenched electrodes. Significantly, the results indicate that Mn and Ni dissolution are suppressed by annealing, further supporting previous findings that showed an increase in the relative concentration of Mn4+ to Mn3+ and a decrease in the Ni/Li interlayer mixing for the annealed material relative to the quenched material. The formation of Mn and Ni fluorides and the suppression of highly resistive LiF upon cycling appear to play an important role toward the improved capacity retention of annealed LiN0.5Mn0.5O2.

AB The stress, sigma, required to penetrate a commercial magnetorheological (MR) fluid exposed to an applied magnetic field, B, in the range of 0 - 0.25 Tesla was determined for: (a) a constant, continuous field and (b) on-off field. With constant field application, it was found that sigma vs. the penetration depth, x, of the cylindrical indenter into the MR fluid at a constant rate of 0.12-0.18 mm/s was parabolic in form, namely sigma = sigma(o)x(n) where sigma(0) = AH, A = 1.7 kPa/(kA/m) and n = 0.3-0.5. The magnitude of so is approximately six times that of the shear yield stress, tau(y), of the MR fluid. A model is proposed to explain the resistance to penetration into the MR fluid with the constant field. The results obtained in the on-off field tests and the in-out tests are in keeping with the model.

AB The use of a spatially distributed set of sensors has become a cost-effective approach to achieve surveillance coverage against moving targets. As more sensors are utilized in a collaborative manner, the optimal placement of sensors becomes critical to achieve the most efficient coverage. In this paper, we develop a numerical optimization approach to place distributed sets of sensors to perform surveillance against moving targets over extended areas. In particular, we develop a genetic algorithm solution to find spatial sensor density functions that maximize effectiveness against moving targets, where the surveillance performance of individual sensors is dependent on their absolute position in the region as well as their relative position to both the expected target(s) and any asset that is being protected. The density function representation of optimal sensor locations is shown to provide a computationally efficient method for determining sensor asset location planning. We illustrate the effective performance of this method on numerical examples based on problems of general area surveillance and risk-based surveillance in protection of an asset.

AB Electrochemical double-layer capacitors (EDLCs) are well suited to time-dependent electrical power output, but in terms of their overall energy density, these devices are much more limited in comparison to Li ion batteries. However, asymmetric supercapacitors that utilize a lithiated negative electrode and a high surface area positive electrode can result in significant improvements in the overall energy density of the device. Key to the development of a LixC6 asymmetric supercapacitor, or Li ion capacitor, is the preparation of the lithiated negative electrode. A common method of accomplishing this is to allow Li ions to intercalate into the carbon material under a spontaneous potential gradient. However, the insertion process can be very slow and may take several hours to reach equilibrium. However, an electrochemically driven lithiation process could significantly decrease the electrode preparation time, which would have great benefits for the development of these devices. Three methods for the insertion of Li into activated carbon electrodes were evaluated in this work that examined the examined the effect of electrochemically-driven lithiation of an activated carbon powder electrode as it may compare to unaided lithiation. In addition, in one of the configurations, the sacrificial Li metal electrode faced the 'back' side of the carbon electrode, which provides the advantage in that the cell would not have to be disassembled and re-assembled to evaluate the completed Li capacitor cell, since the positive electrode could readily be added to the cell during the initial assembly. During the lithiation process, the current flow and total charge passed were monitored and an electrochemical impedance analysis was performed to gain insight into the formation of the SEI layer on the carbon surface during the Li insertion process.

AB We have characterized the single-event transient sensitivity to gate bias of InAlSb/InAs/AlGaSb high electron mobility transistors through experiments and simulations. These depletion-mode transistors exhibit increased charge collection as the gate bias moves from depletion toward threshold, similar to the response observed in floating body silicon-on-insulator devices. Maximum charge collection occurs near threshold, decreasing as the gate bias moves toward accumulation. The interplay between the longitudinal electric field in the channel and the vertical electric field underneath the gate affects the net radiation-generated charge in the InAs channel, which is responsible for the observed experimental trends.

AB Density estimation for marine mammal species is performed primarily using visual distance sampling or capture-recapture. Minke whales in Hawaiian waters are very difficult to sight; however, they produce a distinctive "boing" call, making them ideal candidates for passive acoustic density estimation. We used an array of 14 bottom-mounted hydrophones, distributed over a 60 x 30 km area off Kauai, Hawaii, to estimate density during 12 d of recordings in early 2006. We converted the number of acoustic cues (i.e., boings) detected using signal processing software into a cue density by accounting for the false positive rate and probability of detection. The former was estimated by manual validation, the latter by applying spatially explicit capture-recapture (SECR) methods to a subset of data where we had determined which hydrophones detected each call. Estimated boing density was 130 boings per hour per 10,000 km(2) (95% CI 104-163). Little is known about the population's acoustic behavior, so conversion from boing to animal density is difficult. As a demonstration of the method, we used a tentative boing rate of 6.04 boings per hour, from a single animal tracked in 2009, to give an estimate of 21.5 boing-calling minke whales per 10,000 km(2).

AB Sexual offenders are increasingly reported to use condoms while committing the crime, mainly to prevent the transfer of DNA evidence. Although condoms are often removed from the crime scene, vaginal swabs can be taken from the victim to prove the presence of condom lubricants and therefore evidence of corpus delicti. However, late reporting to the police and the tendency of the victim to wash immediately after the crime, may compromise the detection of condom lubricants. Recently we showed that Matrix-Assisted Laser Desorption/Ionisation MS Imaging (MALDI MSI) of condom contaminated fingermarks enables images of the fingermark ridge pattern to be obtained simultaneously with the detection of the condom lubricant for two condom brands, thus becoming a potential alternative way to link the assailant to the crime. Building on the value of this information, it would be advantageous to identify the condom brand used during the sexual assault. Here we show the development of a multidisciplinary spectroscopic approach, including MALDI MSI, MS/MS, Raman microscopy and ATR-FTIR spectroscopy, applied to a range of condom brands/types. The techniques have complementary features and provide complementary information to retrieve a "condom brand spectroscopic fingerprint". Unique spectroscopic profiles would greatly aid in the screening and identification of the condom, thus adding intelligence to the case under investigation.

AB This article reviews the discovery, development, and use of high-frequency (HF) radio wave backscatter in oceanography. HF radars, as the instruments are commonly called, remotely measure ocean surface currents by exploiting a Bragg resonant backscatter phenomenon. Electromagnetic waves in the HF band (3-30 MHz) have wavelengths that are commensurate with wind-driven gravity waves on the ocean surface; the ocean waves whose wavelengths are exactly half as long as those of the broadcast radio waves are responsible for the resonant backscatter. Networks of HF radar systems are capable of mapping surface currents hourly out to ranges approaching 200 km with a horizontal resolution of a few kilometers. Such information has many uses, including search and rescue support and oil-spill mitigation in real time and larval population connectivity assessment when viewed over many years. Today, HF radar networks form the backbone of many ocean observing systems, and the data are assimilated into ocean circulation models.

DE Cosmic rays; supernovae; gamma rays
AB Cosmic rays are thought to be accelerated at supernova remnant (SNR) shocks, but observation of the pi(0) bump that would confirm this expectation is hampered by weak gamma-ray fluxes of SNRs, instrumental difficulties in observing low energy (less than or similar to 100 MeV) emissions, background gamma rays made from cosmic-ray interactions with gas and dust in the vicinity of SNRs, leptonic gamma rays, and gamma-ray point sources. By contrast, cosmic-ray bombardment of nearby high-latitude gas located away from known molecular cloud complexes and with small ionized hydrogen column density along the line of sight provides a less confused emission region for study. The Large Area Telescope on the Fermi Gamma-ray Space Telescope has measured a gamma-ray spectrum of high-latitude gas that reveals a low-energy cutoff corresponding to a pi(0) -> 2 gamma feature [1].
A shock-accelerated particle flux proportional to p(-s), where p is the particle momentum, follows from simple theoretical considerations of cosmic-ray acceleration at nonrelativistic shocks followed by rigidity-dependent escape into the Galactic halo. A flux of shock-accelerated cosmic-ray protons with s approximate to 2.8 provides an adequate fit to the Fermi-LAT gamma-ray emission spectrum of high-latitude gas when uncertainties in secondary nuclear production models are taken into acount. The cosmic-ray spectrum inferred from the gamma-ray emissivity spectrum is in accord with the SNR hypothesis for the origin of the cosmic rays [2].

AB In spite of major observational advances in high-energy astronomy, the problem of UHECR origin has defied solution. Nevertheless, candidate sources can be ruled out on the basis of physical arguments and available data. For example, only a few source classes remain viable after requiring that the sources of UHECRs are extragalactic, that some of the sources are found within the GZK radius, and that they have adequate emissivity to explain the UHECR intensity and adequate power to accelerate the highest energy UHECRs. Features in the gamma-ray spectra of blazars observed with Fermi at GeV energies, and with ground-based gamma-ray telescopes at very-high energies (VHE; greater than or similar to 100 GeV), favor acceleration of UHECRs in blazar black-hole jets.

AB Looping motions of RAFOS floats deployed off the Central California coast between 1992 and 2010 are described. Most floats were deployed in the California Undercurrent. Floats at 300 m were observed to loop 26% of the time, with anticyclonic rotation observed about twice as often as cyclonic rotation. Characteristics of anticyclonic rotation at 300 m included median swirl speeds of 14 cm/s for diameters of 59 km and 14-day periods. Long-lived (> 70 days and at least 8 consecutive loops) anticyclonic loopers are identified as California Undercurrent eddies (or "cuddies"). One cuddy was observed to move southwestward 1650 km over a period of 520 days before observations ended. Kinematically, cuddies are similar to Mediterranean Water eddies (meddles) in the Iberian Basin, except that meddies are somewhat stronger, larger and deeper.
Over the slope, most cuddies were formed between either Pt. Sur and Pt. Reyes or Cape Mendocino and Cape Blanco. The region north of Cape Mendocino is estimated to generate six cuddles each year. These eddies form from waters on the inshore side of the California Undercurrent as they move past Cape Mendocino. Topographic drag is the most likely formation mechanism.
Two of eight deep floats were observed to loop, one anticyclonically (1545 m) for 279 days and the other cyclonically (1167 m) for 192 days. Looping for these floats ended near Taney Seamounts. Published by Elsevier Ltd.

Fabrication was carried out via ultraviolet photolithography (UV-LIGA) using the SU-8 photoresists. Two cold test methods used to characterize the microfabricated circuits are reported and reveal excellent agreement with simulations. This type of all-copper grating also shows potential for use as a high-average-power sharp-cutoff filter.

AB A cache feature salvaged from an eroding sea cliff on San Nicolas Island produced two redwood boxes containing more than 200 artifacts of Nicoleno, Native Alaskan, and Euro-American origin. Outside the boxes were four asphaltum-coated baskets, abalone shells, a sandstone dish, and a hafted stone knife. The boxes, made from split redwood planks, contained a variety of artifacts and numerous unmodified bones and teeth from marine mammals, fish, birds, and large land mammals. Nicoleno-style artifacts include 11 knives with redwood handles and stone blades, stone projectile points, steatite ornaments and effigies, a carved stone pipe, abraders and burnishing stones, bird bone whistles, bone and shell pendants, abalone shell dishes, and two unusual barbed shell fishhooks. Artifacts of Native Alaskan style include four bone toggling harpoons, two unilaterally barbed bone harpoon heads, bone harpoon fore-shafts, a ground slate blade, and an adze blade. Objects of Euro-American origin or materials include a brass button, metal harpoon blades, and ten flaked glass bifaces. The contents of the cache feature, dating to the early-to-mid nineteenth century, provide an extraordinary window on a time of European expansion and global economic development that created unique cultural interactions and social transformations.

AB Soft materials (e. g., enveloped viruses, liposomes, membranes and supercooled liquids) simultaneously deform or display collective behaviors, while undergoing atomic scale vibrations and collisions. While the multiple space-time character of such systems often makes traditional molecular dynamics simulation impractical, a multiscale approach has been presented that allows for long-time simulation with atomic detail based on the co-evolution of slowly varying order parameters (OPs) with the quasi-equilibrium probability density of atomic configurations. However, this approach breaks down when the structural change is extreme, e. g., when nearest-neighbor connectivity between structural subsystems is not maintained. In the current study, a self-consistent approach is presented wherein OPs and a reference structure co-evolve slowly to yield long-time simulation for dynamical soft-matter phenomena such as structural transitions and self-assembly. The development begins with the Liouville equation for N classical atoms and an ansatz on the form of the associated N-atom probability density. Multiscale techniques are used to derive Langevin equations for the coupled OP-configurational dynamics. The net result is a set of equations for the coupled stochastic dynamics of the OPs and centers of mass of the subsystems that constitute a soft material body. The theory is based on an all-atom methodology and an interatomic force field, and therefore enables calibration-free simulations of soft matter, such as macromolecular assemblies.

AB Little is known about the sexual well-being of male Veteran cancer survivors, or the relationship of sexual concerns to psychosocial adaptation postcancer. This study examined the association between sexual self-esteem and psychosocial concerns in male Veteran cancer survivors. Forty-one male survivors were recruited from a Veterans Affairs (VA) hospital to participate in a pilot study addressing cancer survivorship care for Veterans. Sixty- to 90-minute interviews were conducted, assessing sociodemographic, medical, stress/burden (cancer-related posttraumatic stress disorder [PTSD], depression), and resource (social support, post-traumatic growth) variables. Twenty-one (51.2%) Veteran cancer survivors reported lowered sexual self-esteem as a result of cancer, which corresponded to significantly higher levels of depression and cancer-related PTSD. The lowered sexual self-esteem group also indicated significantly lower social support. Veteran cancer survivors with lowered sexual self-esteem tend to have higher levels of stress and lower levels of resources, putting them at risk for lowered quality of life. This increased risk highlights the importance of addressing sexual well-being in the survivorship care of Veterans.

ID SUPERPLASTIC AA5083; MECHANISMS
AB Thermomechanical processing to enable superplasticity in AA5083 materials includes cold working followed by heating prior to hot blow forming. Upon heating for forming at 450 degrees C, a B-type ({110}< 112 >) rolling texture is replaced by a near-random texture with a weak superimposed cube < 001 > orientation parallel to the sheet normal. The presence of refined grains 7 - 8 mu m in size reflects the predominance of particle-stimulated nucleation of recrystallization prior to forming. The subsequent evolution of microstructure, texture and cavitation behaviour during biaxial deformation in the solute drag creep (SD C) and grain boundary sliding (GBS) regimes will be presented.

Shewanella oneidensis DSP-10 was cultivated in laboratory medium and then fixed on a carbon felt electrode via a silica sol-gel process in order to catalyze anodic fuel cell processes. The cathode electrocatalyst was composed of bilirubin oxidase, fixed to a carbon nanotube electrode using a heterobifunctional cross linker, and then stabilized with a silica sol-gel coating. The anode and cathode half-cells provided operating potentials of -0.44 and 0.48 V, respectively (vs. Ag/AgCl). The HBFC maintained a reproducible open circuit voltage >0.7 V for 9 d in laboratory settings and sustained electrocatalytic activity for >24 h in open environment tests. Published by Elsevier Ltd.

DEPRESSION; SEVERITY; PROTECTION; PERSONNEL; VETERANS; EXPOSURE
AB Hearing is critical to the performance of military personnel and is integral to the rapid and accurate processing of speech information. Thus, noise-induced hearing loss (NIHL) represents a severe impairment that reduces military effectiveness, safety, and quality of life. With the high levels of noise to which military personnel are exposed and the limited protection afforded by hearing conservation programs, it should be no surprise that annual Veterans Affairs disability payments for tinnitus and hearing loss exceeded $1.2 billion for 2009 and continue to increase. Military personnel work in high-noise environments, yet the Department of Defense (DoD) cannot predict who is susceptible to noise-induced hearing loss and tinnitus. Of those exposed to noise, 80% may also suffer from chronic tinnitus. Despite its prevalence, there are no means to objectively measure the severity of tinnitus in those individuals. A fundamental understanding of the underlying mechanisms of tinnitus and its relation to noise-induced hearing loss is critical. Such an understanding may provide insight to who is at risk for each condition, allow aggressive hearing protection measures in those individuals most at risk, and create areas for treatment for those already suffering from the conditions. The current review will address the scope of the problems of NIHL and tinnitus for the military, discuss the noise environments in which military personnel operate, describe the hearing conservation measures currently in place, and the challenges those programs face. Some recent breakthroughs in NIHL research will be discussed along with some challenges and directions for future research on NIHL and tinnitus. Published by Elsevier B.V.

Opt. 2011, 58 (21), 2028--2035] to theoretically and experimentally investigate in detail Raman transitions in a sample of laser cooled 85Rb. Using cross-linearly polarized Raman fields, we find that, for an arbitrarily oriented magnetic field, the Raman spectrum consists of up to eleven peaks. However, by judicious choice of magnetic field direction, the spectrum can be reduced to a five peaked spectrum (transverse magnetic field) or a six peaked spectrum (longitudinal magnetic field). We present cases in which the full spectrum can not be thought of as the incoherent sum of the five and six peaked spectra.

AB Knowledge is key to competitive advantage, and the social reach of knowledge can amplify its power in terms of organizational performance. Leveraging such amplification, social media applications are expected broadly to improve the performance of organizational work, which highlights teams, groups, and organizations as particularly appropriate units of analysis. The technological intermediation of knowledge work within and among such social aggregations of people remains a complex endeavor, however. This pertains in particular to immersive, 3D environments supporting virtual social and game worlds. As with other social media applications, such virtual worlds can amplify knowledge broadly, but they also offer potential to approach the sensations of face-to-face (F2F) interaction in terms of presence, copresence, psychological engrossment, and affective experience. In this exploratory study, we employ both quantitative and qualitative research techniques to investigate how teamwork performed through virtual worlds can approach that accomplished via F2F interactions. This leads to important findings, insights, guidelines, and suggestions for expanded research as well as enhanced practice.

AB To increase the sensitivity of uncooled thermal sensors in the terahertz (THz) spectral range (1 to 10 THz), we investigated thin metamaterial layers exhibiting resonant absorption in this region. These metamaterial films are comprised of periodic arrays of aluminum (Al) squares and an Al ground plane separated by a thin silicon-rich silicon oxide (SiOx) dielectric film. These standard MEMS materials are also suitable for fabrication of bi-material and microbolometer thermal sensors. Using SiOx instead of SiO2 reduced the residual stress of the metamaterial film. Finite element simulations were performed to establish the design criteria for very thin films with high absorption and spectral tunability. Single-band structures with varying SiOx thicknesses, square size, and periodicity were fabricated and found to absorb nearly 100% at the designed frequencies between three and eight THz. Multiband absorbing structures were fabricated with two or three distinct peaks or a single-broad absorption band. Experimental results indicate that is possible to design very efficient thin THz absorbing films to match specific applications. (C) The Authors.

AB A catalyst free approach for nitrogen oxides (NOx) removal has been developed at the United States Naval Research Laboratory. Our goals were to assess the ability of pulsed electron beam to enhance NOx removal at potential lower capital cost with greater efficiency than other large scale NOx removal methods. Removal efficiency over 95% has been attained for NOx concentrations of 1000 parts per million (ppm), 500 ppm and 200 ppm in nitrogen atmosphere. The NOx concentration dropped from 204 ppm to below 4.8 ppm after 10 shots supplying a total dose of 65 kGy. The resultant chemicals after catalyst free pulsed electron beam processing of NOx are nitrogen and oxygen, same as components of air. Pulsed electron beams in a catalyst free approach remove a larger percentage of NOx than continuous wave electron beam with a catalyst. Catalyst free approach removes issues of handling, collecting, transporting and efficiently distributing chemical byproducts. Pulsed electron beams are as efficient as continuous wave electron beams for small removal percentages and have a significant advantage at higher fractional removal percentages of NOx. Preferential destruction of NO species relative to the removal of NO2 species is observed in the pulsed electron beam reaction chamber. The energy required to remove a kilogram of NOx is nearly the same at pressures of 1.16 atmospheres and 1.02 atmospheres.

With child-fixed-effect models and a baseline period that is long before the divorce, the estimates rely on within-child changes over time. Youth are more likely to use alcohol 2-4 years before a parental divorce. After the divorce, youth have an increased risk of using alcohol and marijuana, with the effect for marijuana being 12.1 percentage points in the two years right after the divorce (p = .010). The magnitudes of the effects persist as time passes from the divorce.

AB Crew members on cruise ships are hired in a global labor market, and a major cost for cruise lines is moving crew members from their home cities to the cruise ship's departure port. Complicating the crew scheduling problem is the uncertainty due to no-shows, terminations, and other reasons for crew to terminate their contract prematurely. To address this problem, this paper describes a scheduling system that implements a two-stage planning process that first determines overbooking levels for the number of crew to offer contracts to, and then second, a goal integer programming formulation to minimize the movement cost of assigning crew to ships while maintaining adequate crew levels and a desired crew region composition. We solve actual-sized problems characteristic of the cruise industry in a reasonably short amount of time. Experiments comparing the actual crew movement costs to the system's projected crew movement costs show that the scheduling system can consistently reduce the movement costs in the range of 9-23%, better maintain desired crew levels, and better maintain desired crew region composition.

AB Introduction: We aimed to identify potential risk factors for intussusception (ISS) among children presenting to two pediatric hospitals in Egypt.
Methodology: In this case-control study, enrolled children < 3 years old with ISS (confirmed radiologically and/or surgically) were matched by age and gender to controls admitted with acute non-abdominal surgical illnesses. Stool samples were collected and tested for various enteric bacteria, rotavirus, enteric adenoviruses (EA, 40 and 41) and astroviruses using commercially available ELISA diagnostic kits.
Results: From December 2004 to May 2009, 158 cases and 425 matched controls were enrolled. A history of diarrhoea and cough over the preceding four weeks of interview were more common in cases than controls, respectively. Children with mothers who had secondary education and above were 2.2 times more likely to have ISS than those whose mothers had a lower level of education. In spite of the low detection rate of EA infection (regardless of diarrhoea history) and asymptomatic rotavirus infection, they were detected in higher frequencies in cases than controls; however, infection with astrovirus and bacterial pathogens did not appear to be associated with increased risk of ISS.
Conclusions: History of diarrhoea and cough over the four weeks preceding the study and maternal education above secondary level were potential risk factors for ISS. EA and asymptomatic rotavirus infection were detected in higher frequencies among cases than controls; however, association with ISS cannot be confirmed. Additional research is needed to confirm these findings and evaluate the pathogenesis which may link such infections with ISS.

AB Dengue virus (DENV) is a mosquito-transmitted single stranded RNA virus belonging to genus Flavivirus. The virus is endemic in the tropical and subtropical countries of the world, causing diseases classified according to symptoms and severity (from mild to severe) as dengue fever, dengue hemorrhagic fever, and dengue shock syndrome. Among a variety of human cell types targeted by DENV, monocytes, macrophages, and dendritic cells are members of innate immunity, capable of mounting rapid inflammatory responses. These cells are also major antigen presenting cells, responsible for activating the adaptive immunity for long-term memory. This paper is an overview of the current understanding of the following mutually affected aspects: DENV structure, viral infectivity, cellular receptors, innate immune response, and adaptive immunity.

AB Observations and third-generation wave model hindcasts of ocean surface gravity waves propagating across the Louisiana shelf show that the effects of the mud environment on wave evolution are complex and episodic. Whereas low-frequency waves (0.04-0.20 Hz) show a consistent decay similar to earlier studies, the presence of mud also appears to suppress the development of short waves (0.20-0.25 Hz) under fetch-limited growth conditions. Significant suppression of wave development under wind-forced conditions is found to occur almost exclusively during easterly winds when satellite images show the Atchafalaya mud plume extends into the study area. These results suggest that episodic sediment suspension events with high mud concentrations in the upper water column can affect the evolution of wind waves. (c) 2012 Elsevier Ltd.

AB Conformal nanoscale coatings of Na+-birnessite manganese oxide (MnOx) produced via redox reaction between aqueous permanganate (NaMnO4 center dot H2O) and the carbon surfaces of fiber-paper-supported carbon nanofoams are converted to LiMn2O4 spinel through topotactic exchange of Na+ for Li+ in the as-deposited lamellar birnessite, followed by mild thermal treatments to complete the transformation to LiMn2O4. The evolution of the birnessite-to-spinel conversion is verified with X-ray diffraction, solid-state nuclear magnetic resonance, X-ray absorption spectroscopy, electron microscopy, cyclic voltammetry, and electrochemical impedance spectroscopy. The mild conditions used to convert birnessite to spinel ensure that the conformal nanoscale nature of the oxide coating is retained throughout the macroscopically thick (170 mu m) carbon nanofoam substrate during the conversion process. The architecture of the LiMn2O4-carbon nanofoam facilitates rapid ion/electron transport, enabling the LiMn2O4 to insert and extract Li+ from aqueous electrolytes at scan rates as high as 25 mV s(-1), and with a relaxation time of 37 s as derived from electrochemical impedance. This architectural expression of nanoscale LiMn2O4 delivers full theoretical capacity (148 mA h g(-1)) at 2 mV s(-1).

AB The contact resistance and wear behavior of electrical contact surfaces is a function of hardness, applied load, and material constituents. This work presents a characterization of the mechanical and physical properties of conducting alloys fabricated as functionally graded metal matrix composites (MMCs), in particular, tungsten-carbide-filled bronze. Tungsten-carbide reinforcing particles are attractive in this application for their high hardness and concomitant wear resistance. When used as bushings, bearings, and sleeve materials, bronze has improved wear performance with the addition of tungsten-carbide particles, which improves the hardness of the contact surface. Bronze might also be attractive as a potential electrical conductor when a need exists for high-strength, wear-resistant contact surfaces as found in circuit breakers and sliding electrical contacts. An overview of two types of MMC production methods, sedimentation and centrifugal casting, is presented. MMCs fabricated using the two different methods are compared and contrasted based on physical and mechanical properties. The use of centrifugal casting provides a more effective improvement in physical and mechanical properties plus significant improvement in hardness with relatively low reduction in base-material conductivity was observed. The centrifugal casting method allows for a more tailored product in terms of locating enhanced material properties within the casting.

AB In direct drive inertial confinement laser fusion, a pellet containing D-T fuel is imploded by ablation arising from absorption of laser energy at its outer surface. For optimal coupling, the focal spot of the laser would continuously decrease to match the reduction in the pellet's diameter, thereby minimizing wasted energy. A krypton-fluoride laser (lambda = 248 nm) that incorporates beam smoothing by induced spatial incoherence has the ability to produce a high quality focal profile whose diameter varies with time, a property known as focal zooming. A two-stage focal zoom has been demonstrated on the Nike laser at the Naval Research Laboratory. In the experiment, a 4.4 ns laser pulse was created in which the on-target focal spot diameter was 1.3 mm (full width at half maximum) for the first 2.4 ns and 0.28 mm for the final 2 ns. These two diameters appear in time-integrated focal plane equivalent images taken at several locations in the amplification chain. Eight of the zoomed output beams were overlapped on a 60 mu m thick planar polystyrene target. Time resolved images of self-emission from the rear of the target show the separate shocks launched by the two corresponding laser focal diameters. (C) 2013 American Institute of Physics.

SO SHOCK AND VIBRATION

DE Underwater explosion; ocean floor modeling; shallow water; fluid
structure interaction
AB Current practices for modeling the ocean floor in underwater explosion simulations call for application of an inviscid fluid with soil properties. A method for modeling the ocean floor as a Lagrangian solid, vice an Eulerian fluid, was developed in order to determine its effects on underwater explosions in shallow water using the DYSMAS solver. The Lagrangian solid bottom model utilized transmitting boundary segments, exterior nodal forces acting as constraints, and the application of prestress to minimize any distortions into the fluid domain. For simplicity, elastic materials were used in this current effort, though multiple constitutive soil models can be applied to improve the overall accuracy of the model. Even though this method is unable to account for soil cratering effects, it does however provide the distinct advantage of modeling contoured ocean floors such as dredged channels and sloped bottoms absent in Eulerian formulations. The study conducted here showed significant differences among the initial bottom reflections for the different solid bottom contours that were modeled. The most important bottom contour effect was the distortion to the gas bubble and its associated first pulse timing. In addition to its utility in bottom modeling, implementation of the non-reflecting boundary along with realistic material models can be used to drastically reduce the size of current fluid domains.

AB Direct, tunable coupling between individually assembled graphene layers is a next step toward designer two-dimensional (2D) crystal systems, with relevance for fundamental studies and technological applications. Here we describe the fabrication and characterization of large-area (>cm(2)), coupled bilayer graphene on SiO2/Si substrates. Stacking two graphene films leads to direct electronic interactions between layers, where the resulting film properties are determined by the local twist angle. Polycrystalline bilayer films have a "stained-glass window" appearance explained by the emergence of a narrow absorption band in the visible spectrum that depends on twist angle. Direct measurement of layer orientation via electron diffraction, together with Raman and optical spectroscopy, confirms the persistence of clean interfaces over large areas. Finally, we demonstrate that interlayer coupling can be reversibly turned off through chemical modification, enabling optical-based chemical detection schemes. Together, these results suggest that 2D crystals can be individually assembled to form electronically coupled systems suitable for large-scale applications.

AB Reflective roofs can reduce demand for air conditioning and warming of the atmosphere. Roofs can also host photovoltaic (PV) modules that convert sunlight to electricity. In this study we assess the effects of installing a building integrated photovoltaic (BIPV) roof on an office building in Yuma, AZ. The system consists of thin film PV laminated to a white membrane, which lies above a layer of insulation. The solar absorptance of the roof decreased to 0.38 from 0.75 after installation of the BIPV, lowering summertime daily mean roof upper surface temperatures by about 5 degrees C. Summertime daily heat influx through the roof deck fell to +/- 0.1 kWh/m(2) from 0.3-1.0 kWh/m(2). However, summertime daily heat flux from the ventilated attic into the conditioned space was minimally affected by the BIPV, suggesting that the roof was decoupled from the conditioned space. Daily PV energy production was about 25% of building electrical energy use in the summer. For this building the primary benefit of the BIPV appeared to be its capacity to generate electricity and not its ability to reduce heat flows into the building. Building energy simulations were used to estimate the cooling energy savings and heating energy penalties for more typical buildings. (c) 2012 Elsevier B.V. All rights reserved.

AB Spatial and temporal decorrelation scales in phytoplankton bloom magnitudes are reviewed with the goal of informing the design of efficient and informative observing networks for monitoring of potentially harmful algal blooms (HABs) along the U.S. West Coast. Our analysis of historic MODIS Fluorescent Line Height data shows that, unlike several previous studies, seasonal timing of phytoplankton blooms off the U.S. West Coast propagates from South to North. In situ data show that temporal decorrelation scales are shortest off Northern California (similar to 4 days) and longest in the Southern California Bight (similar to 17 days). In a cross-shore direction, we find that variability in the near-shore biomass is decoupled from biomass further offshore (similar to 2-4 km).
Our review of the cloud cover gap statistics suggests that satellite data provide reasonably inexpensive information about bloom events, particularly at seasonal to inter-annual scales, but is insufficient to capture many event-scale blooms. Absent adequate satellite data, in situ monitoring becomes essential. Existing networks of automated monitoring sites from piers and moorings off the California coast is insufficient to describe regional variability in blooms, but is likely informative of bloom magnitudes in the immediate proximity of observation stations. We suggest that a more effective network will have a combination of shore-based stations and a few (5-10) offshore moorings. Shore-based stations should be located in proximity to sensitive HAB targets. This would provide monitoring of existing conditions and guide decision-making about beach closures and aquaculture management practices. Offshore stations can serve as proxy for regional conditions and can be used to issue early warnings of potential HAB conditions developing in a specific region. (C) 2012 Elsevier B.V.

AB The energetic derivatives of 5-nitro-1,2,3-2H-triazole, which include 2-(methyl or amino)-4-(nitramino, azido, or nitro)-5-nitro-1,2,3-2H-triazoles, were prepared in moderate yields, and confirmed with NMR and IR spectroscopy, and elemental analysis. Their key properties, viz., melting and decomposition temperatures, densities, detonation pressures and velocities, and impact sensitivities, were measured or calculated. Among the new derivatives, 2-amino-4,5-dinitro-1,2,3-2H-triazole exhibits properties (T-m, 94 degrees C; T-d, 190 degrees C; rho, 1.83 g cm(-3); P, 36.2 Gpa, v(D), 8843 m s(-1), IS, 24 J), comparable with RDX (T-m, 205 degrees C; T-d, 230 degrees C; rho, 1.80 g cm(-3); P, 35.0 Gpa, v(D), 8762 m s(-1), IS, 7.5 J), and may have potential as a high-performance energetic material.

AB The impressive specific capacitance and high-rate performance reported for many nanometric charge-storing films on planar substrates cannot impact a technology space beyond microdevices unless such performance translates into a macroscale form factor. In this report, we explore how the nanoscale-to-macroscale properties of the electrode architecture (pore size/distribution, void volume, thickness) define energy and power performance when scaled to technologically relevant dimensions. Our test bed is a device-ready electrode architecture in which scalable, manufacturable carbon nanofoam papers with tunable pore sizes (5-200 nm) and thickness (100-300 mm) are painted with similar to 10 nm coatings of manganese oxide (MnOx). The quantity of capacitance and the rate at which it is delivered for four different MnOx-C variants was assessed by fabricating symmetric electrochemical capacitors using a concentrated aqueous electrolyte. Carbon nanofoam papers containing primarily 10-20 nm mesopores support high MnOx loadings (60 wt%) and device-level capacitance (30 F g(-1)), but the small mesoporous network hinders electrolyte transport and the low void volume restricts the quantity of charge-compensating ions within the electrode, making the full capacitance only accessible at slow rates (5 mV s(-1)). Carbon nanofoam papers with macropores (100-200 nm) facilitate high rate operation (50 mV s(-1)), but deliver significantly lower device capacitance (13 F g(-1)) as a result of lower MnOx loadings (41 wt%). Devices comprising MnOx-carbon nanofoams with interconnecting networks of meso-and macropores balance capacitance and rate performance, delivering 33 F g(-1) at 5 mV s(-1) and 23 F g(-1) at 50 mV s(-1). The use of carbon nanofoam papers with size-tunable pore structures and thickness provides the opportunity to engineer the electrode architecture to deliver scalable quantities of capacitance (F cm(-2)) in tens of seconds with a single device.

AB We examine aspects of the thermodynamic structure of mature Atlantic hurricane Earl (2010) based on airborne dropwindsondes released from the upper troposphere during the National Aeronautics and Space Administration (NASA), Genesis and Rapid Intensification Processes (GRIP) experiment. Vertical sounding profiles of the data raise questions concerning the relative roles of isothermal expansion and relative humidity increase in elevating the equivalent potential temperature of air parcels spiralling inwards to the eyewall convection region. The observational results obtained for two successive days of this category 4 hurricane show that the isothermal expansion effect leads to roughly one half of the increment in equivalent potential temperature for boundary-layer air parcels moving between the region outside the eyewall and the eyewall and eye region.

AB This article presents the adjoint-data assimilation system (adjoint-DAS) approach to evaluate the forecast sensitivity with respect to the specification of the observation-error covariance (R-sensitivity) and background-error covariance (B-sensitivity) in a four-dimensional variational (4D-Var) DAS with a single outer-loop iteration. Computationally efficient estimates to the forecast impact of adjustments in the error covariance models are obtained by exploiting the mathematical properties of the R- and B-sensitivity matrices and their relationship with the observation sensitivity vector. An additional contribution of this work is that it establishes a synergistic link between various methodologies to analyze the DAS performance: observation sensitivity and impact assessment, error covariance sensitivity, and a posteriori diagnosis. The practical ability to obtain sensitivity information with respect to R- and B-parameters is presented with the adjoint versions of the Naval Research Laboratory Atmospheric Variational Data Assimilation SystemAccelerated Representer (NAVDAS-AR) and the Navy Operational Global Atmospheric Prediction System (NOGAPS). The adjoint approach is used to provide guidance on the forecast impact of weighting the radiance data in the DAS according to observation-error variance estimates derived from an a posteriori diagnosis. The results indicate that information extracted from both error covariance diagnosis and sensitivity analysis is necessary to design parameter tuning procedures that are effective in reducing the forecast errors.

AB The effects of polyurea coatings on the response of E-Glass/Vinyl ester curved composite panels subjected to underwater explosive loading has been studied. The thickness and location of the polyurea coating has been varied to determine how these parameters affect the transient response. The composite material is a 0 degrees/90 degrees biaxial layup and the coatings are applied to either the loaded or non-loaded faces. The current work utilizes a conical shock tube facility which produces shock loading conditions equivalent to the underwater detonation of an explosive charge. The transient response of the plates is recorded using a three-dimensional (3D) Digital Image Correlation system, consisting of high-speed photography and specialized post processing software. The results show that for a given polyurea thickness, better performance is obtained when the back face of the panel is coated. Similarly the performance is improved as the coating thickness is increased; however this comes at a cost in terms of increased areal weight. The results show that there is likely an optimal coating thickness, that when located on the back face, provides a balanced tradeoff between panel performance and weight increase.

AB A model-based correlation detection scheme is presented with the aim of detecting and localizing subsurface tunnel infrastructure in an automated fashion. Our goal is to develop a comprehensive detection technology that can be fielded and successfully used by nonexperts, while simultaneously being sufficiently robust as to be effective. Our correlation detection algorithm relies on a library of model signals that are generated using an analytical model of a thin subsurface wire in a homogeneous half-space. The wire is illuminated using an active transmitter source (12, 20, or 200 kHz), and its response is sensed using a man-portable electromagnetic gradiometer (EMG) system. The performance of the detector is assessed using synthetic data and receiver operating characteristic (ROC) analysis as well as experimental data collected during a field test. Preliminary ROC results indicate that at sufficient signal-to-noise ratio, the detector can achieve detection probabilities greater than 0.9 with corresponding false alarm rates of less than one every 1000 m. Results from the field tests revealed that the responses from the EMG can be used to detect and localize (to within 0.5 m in the horizontal) a wire target down to a depth of at least 7 m. We believe the EMG system and correlation detector combine to form a promising technology for detecting tunnel infrastructure that can be used by experts and, more importantly, nonexperts as well.

AB A submersible consisting of a flexible fluid-conveying tail affixed to a rigid head is described and equations which account for all accelerations and rotations of the submersible within a plane are derived. Solution of these equations with a finite-difference method provides evidence that this type of submersible can produce thrust in excess of a fixed jet; a conclusion which is corroborated by preliminary experimental results. An extension of the dynamic model which uses a time-varying velocity of the conveyed fluid has been provided, and simulations have been performed which show that the submersible can be maneuvered by properly choosing the functional description of this velocity.

TI Analysis of the Monotonic Lagrangian Grid as an Air Traffic Simulation
Tool
SO JOURNAL OF GUIDANCE CONTROL AND DYNAMICS
LA English
DT Article
ID ALGORITHM; DYNAMICS
AB A new research platform, the Air Traffic Monotonic Lagrangian Grid, has been developed to serve as a simulation tool for easy and fast testing of various air traffic system concepts. The underlying algorithm is the Monotonic Lagrangian Grid, which is a fast nearest-neighbors interaction algorithm used for sorting and tracking many moving and interacting objects. The nodes of the Monotonic Lagrangian Grid represent the locations of individual aircraft, and the grid moves at each time step as the aircraft move. The model is used to simulate a 24 h period of air traffic flow in the National Airspace System, during which there are 41,594 flights, and this requires only 79 s of wall-clock time on a single processor of a 1.3 GHz Altix. An analysis is presented of the number of nearest-neighbor nodes that must be checked to ensure adequate separation among aircraft. An investigation of the effect of removing waypoints from aircraft trajectories indicates that this may result in a significant reduction in total flight time. Finally, the model is compared with the traditional Latitude - Longitude grid approach, in which the airspace volume is partitioned into fixed stationary grid cells. Results of the comparison indicate that the main advantage of the Monotonic Lagrangian Grid method is that it is a general sorting algorithm that can sort on multiple properties, providing more computational efficiency.

AB The data from two high-frequency radars (HFR) operating in the Iroise Sea are re-processed by applying an improved version of the direction finding algorithm, removing wave-induced surface currents and the variational interpolation on a regular grid. Combining these processing techniques allowed reconstruction of the surface currents at a level of details that was not previously available. Refined resolution enabled to identify fine-scale structures of surface circulation, to quantify the variability of tidal currents and the residual (time averaged) velocity field, and to explain spatial intermittence in polarization of the tidal current ellipses. The analyzed data span two month-long periods in spring and late summer of 2007. The major findings include (a) a dipole structure in the vorticity field characterized by two oppositely rotating eddies, generated on the leeward side of the Ushant Island at flood (negative polarity) and at ebb (positive polarity); (b) an extremely strong fortnightly variability of tidal currents northwest of the Ushant Island with the highest velocity magnitude of 3.9 m/s caused by the interference of the major semi-diurnal tidal constituents; (c) a significant contribution of the higher order nonlinear tidal harmonics to the surface currents in the Fromveur strait, which maintains strong tidal currents and affects the shape of their fortnightly modulation. The residual circulation is characterized by two distinct zones approximately separated by the 100 m isobath: in the offshore zone the residual currents have a significant contribution of the wind-driven component, whereas the nearshore zone is characterized by extremely strong (up to 0.4 m/s) time-independent residual circulation featuring two permanent anticyclonic eddies: north of the western extremity of the Sein archipelago, and north the Ushant Island. The acquired data and the presented results could be useful for regional model validation and studies of the local eddy dynamics, tidal fronts, and passive tracer transport in the region.

AB In South America, various species of Leishmania are endemic and cause New World tegumentary leishmaniasis (NWTL). The correct identification of these species is critical for adequate clinical management and surveillance activities. We developed a real-time polymerase chain reaction (PCR) assay and evaluated its diagnostic performance using 64 archived parasite isolates and 192 prospectively identified samples collected from individuals with suspected leishmaniasis enrolled at two reference clinics in Lima, Peru. The real-time PCR assay was able to detect a single parasite and provided unambiguous melting peaks for five Leishmania species of the Viannia subgenus that are highly prevalent in South America: L. (V.) braziliensis, L. (V.) panamensis, L. (V.) guyanensis, L. (V.) peruviana and L. (V.) lainsoni. Using kinetoplastid DNA-based PCR as a gold standard, the real-time PCR had sensitivity and specificity values of 92% and 77%, respectively, which were significantly higher than those of conventional tests such as microscopy, culture and the leishmanin skin test (LST). In addition, the real-time PCR identified 147 different clinical samples at the species level, providing an overall agreement of 100% when compared to multilocus sequence typing (MLST) data performed on a subset of these samples. Furthermore, the real-time PCR was three times faster and five times less expensive when compared to PCR - MLST for species identification from clinical specimens. In summary, this new assay represents a cost-effective and reliable alternative for the identification of the main species causing NWTL in South America.

AB Calculations are presented of ground state resonance structure at THz frequencies for molecular clusters of the high explosive RDX using density functional theory (DFT). The spectral features of this resonance structure are due to coupling of resonance modes for ground state excitation. In particular, the coupling among ground state resonance modes provides a reasonable molecular level interpretation of spectral features associated with THz excitation of molecular clusters. THz excitation is associated with frequencies that are characteristically perturbative to molecular electronic states, in contrast to frequencies that can induce appreciable electronic state transition. Owing to this characteristic of THz excitation, one is able to make a direct association between local oscillations about ground-state minima of molecules, either isolated or comprising a cluster, and THz excitation spectra. The DFT software GAUSSIAN was used for the calculations of ground state resonance structure presented here. (C) 2012 Elsevier B.V. All rights reserved.

AB Context. We present maps of the main cooling lines of the neutral atomic gas ([OI] at 63 and 145 mu m and [CII] at 158 mu m) and in the [OIII] 88 mu m line of the starburst galaxy M 82, carried out with the PACS spectrometer on board the Herschel satellite.
Aims. Our aim is to study the nature of the neutral atomic gas of M 82 and to compare this gas with the molecular and ionized gas in the M 82 disk and outflow.
Methods. By applying PDR modeling we were able to derive maps of the main ISM physical parameters, including the optical depth (tau([CII])), at unprecedented spatial resolution (similar to 300 pc).
Results. We can clearly kinematically separate the disk from the outflow in all lines.
The tau([CII]) is less than 1 everywhere, is lower in the outflow than in the disk, and within the disk is lower in the starburst region. The [CII] and [OI] distributions are consistent with PDR emission both in the disk and in the outflow. Surprisingly, in the outflow, the atomic and the ionized gas traced by the [OIII] line both have a deprojected velocity of similar to 75 km s(-1), very similar to the average velocity of the outflowing cold molecular gas (similar to 100 km s(-1)) and several times smaller than the outflowing material detected in H alpha (similar to 600 km s(-1)). This suggests that the cold molecular and neutral atomic gas and the ionized gas traced by the [OIII] 88 mu m line are dynamically coupled to each other but decoupled from the H alpha emitting gas.
Conclusions. We propose a scenario where cold clouds from the disk are entrained into the outflow by the winds where they likely evaporate, surviving as small, fairly dense cloudlets (n(H) similar to 500-1000 cm(-3), G(0) similar to 500-1000, T-gas similar to 300 K). We show that the UV photons provided by the starburst are sufficient to excite the PDR shells around the molecular cores and probably also the ionized gas that flows at the same PDR velocity. The mass of the neutral atomic component in the outflow is >= 2-8 x 10(7) M-circle dot to be compared with that of the molecular component (3.3 x 10(8) M-circle dot) and of the H alpha emitting gas (5.8 x 10(6) M-circle dot). The mass loading factor, (M) over dot(Outflow)/SFR, of the molecular plus neutral atomic gas in the outflow is similar to 2. Energy and momentum driven outflow models can explain the data equally well, if all the outflowing gas components are taken into account.

AB With the 100-m telescope at Effelsberg, 19 ammonia (NH3) maser lines have been detected toward the prominent massive star forming region W51-IRS2. Eleven of these inversion lines, the (J, K) = (6, 2), (5, 3), (7, 4), (8, 5), (7, 6), (7, 7), (9, 7), (10, 7), (9, 9), (10, 9), and (12, 12) transitions, are classified as masers for the first time in outer space. All detected masers are related to highly excited inversion doublets. The (5, 4) maser originates from an inversion doublet similar to 340 K above the ground state, while the (12, 12) transition, at similar to 1450K, is the most highly excited NH3 maser line so far known. Strong variability is seen not only in ortho- but also in para-NH3 transitions. Bright narrow emission features are observed, for the first time, in (mostly) ortho- ammonia transitions, at V-LSR similar to 45 km s(-1), well separated from the quasi-thermal emission near 60 km s(-1). These features were absent similar to 25 years ago and show a velocity drift of about +0.2 km s(-1) yr(-1). The component is likely related to the SiO maser source in W51-IRS2 and a possible scenario explaining the velocity drift is outlined. The 57 km s(-1) component of the (9, 6) maser line is found to be strongly linearly polarised. Maser emission in the (J, K) to (J + 1, K) inversion doublets is strictly forbidden by selection rules for electric dipole transitions in the ground vibrational state. However, such pairs (and even triplets with (J + 2, K)) are common toward W51-IRS2. Similarities in line widths and velocities indicate that such groups of maser lines arise from the same regions, which can be explained by pumping through vibrational excitation. The large number of NH3 maser lines in W51-IRS2 is most likely related to the exceptionally high kinetic temperature and NH3 column density of this young massive star forming region.

AB Passive microwave (PMW) satellite-based precipitation over land algorithms rely on physical models to define the most appropriate channel combinations to use in the retrieval, yet typically require considerable empirical adaptation of the model for use with the satellite measurements. Although low-frequency channels are better suited to measure the emission due to liquid associated with rain, most techniques to date rely on high-frequency, scattering-based schemes since the low-frequency methods are limited to the highly variable land surface background, whose radiometric contribution is substantial and can vary more than the contribution of the rain signal. Thus, emission techniques are generally useless over the majority of the Earth's surface. As a first step toward advancing to globally useful physical retrieval schemes, an intercomparison project was organized to determine the accuracy and variability of several emissivity retrieval schemes. A three-year period (July 2004-June 2007) over different targets with varying surface characteristics was developed. The PMW radiometer data used includes the Special Sensor Microwave Imagers, SSMI Sounder, Advanced Microwave Scanning Radiometer (AMSR-E), Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI), Advanced Microwave Sounding Units, and Microwave Humidity Sounder, along with land surface model emissivity estimates. Results from three specific targets in North America were examined. While there are notable discrepancies among the estimates, similar seasonal trends and associated variability were noted. Because of differences in the treatment surface temperature in the various techniques, it was found that comparing the product of temperature and emissivity yielded more insight than when comparing the emissivity alone. This product is the major contribution to the overall signal measured by PMW sensors and, if it can be properly retrieved, will improve the utility of emission techniques for over land precipitation retrievals. As a more rigorous means of comparison, these emissivity time series were analyzed jointly with precipitation data sets, to examine the emissivity response immediately following rain events. The results demonstrate that while the emissivity structure can be fairly well characterized for certain surface types, there are other more complex surfaces where the underlying variability is more than can be captured with the PMW channels. The implications for Global Precipitation Measurement-era algorithms suggest that physical retrievals are feasible over vegetated land during the warm seasons.

ID TRIANGULATION
AB Model selection via exponentially embedded families (EEF) of probability models has been shown to perform well on many practical problems of interest. A key component in utilizing this approach is the definition of a model origin (i.e. null hypothesis) which is embedded individually within each competing model. In this correspondence we give a geometrical interpretation of the EEF and study the sensitivity of the EEF approach to the choice of model origin in a Gaussian hypothesis testing framework. We introduce the information center (I-center) of competing models as an origin in this procedure and compare this to using the standard null hypothesis. Finally we derive optimality conditions for which the EEF using I-center achieves optimal performance in the Gaussian hypothesis testing framework.

AB Retrospective seasonal predictions of tropical cyclones (TCs) in the three major ocean basins of the Northern Hemisphere are performed from 1990 to 2010 using the Geophysical Fluid Dynamics Laboratory High-Resolution Atmospheric Model (HiRAM) at 25-km resolution. Atmospheric states are initialized for each forecast, with the sea surface temperature anomaly (SSTA) "persisted" from that at the starting time during the 5-month forecast period (July-November). Using a five-member ensemble, it is shown that the storm counts of both tropical storm (TS) and hurricane categories are highly predictable in the North Atlantic basin during the 21-yr period. The correlations between the 21-yr observed and model predicted storm counts are 0.88 and 0.89 for hurricanes and TSs, respectively. The prediction in the eastern North Pacific is skillful, but it is not as outstanding as that in the North Atlantic. The persistent SSTA assumption appears to be less robust for the western North Pacific, contributing to less skillful predictions in that region. The relative skill in the prediction of storm counts is shown to be consistent with the quality of the predicted large-scale environment in the three major basins. It is shown that intensity distribution of TCs can be captured well by the model if the central sea level pressure is used as the threshold variable instead of the commonly used 10-m wind speed. This demonstrates the feasibility of using the 25-km-resolution HiRAM, a general circulation model designed initially for long-term climate simulations, to study the impacts of climate change on the intensity distribution of TCs.

AB Friction stir welding generates periodic features within the weld. These "onion ring" features are associated with variations in both texture and the orientation of that texture along the length of the weld. Analysis of an AA2195 friction stir weld reveals the presence of periodic oscillations between the dominant B and B components of the ideal shear texture, suggesting a periodic reversal in the predominant shear orientation during welding that is inconsistent with current understandings of the friction stir welding process. Microstructural features present in the weld and machine force variations during welding indicate that these textures may arise from the oscillation of an off-centered tool. Such a tool oscillation can generate a periodic extrusion of material around the tool, giving rise to the observed flow features, machine force variations, and reversals of the local shear texture orientations. A new model of material flow during friction stir welding is proposed to explain the observed features.

AB Objective: To describe the prevalence of neurocognitive impairment (NCI) among early diagnosed and managed HIV-infected persons (HIV+) compared to HIV-negative controls.
Methods: We performed a cross-sectional study among 200 HIV+ and 50 matched HIV-uninfected (HIV-) military beneficiaries. HIV+ patients were categorized as earlier (<6 years of HIV, no AIDS-defining conditions, and CD4 nadir >200 cells/mm(3)) or later stage patients (n = 100 in each group); both groups were diagnosed early and had access to care. NCI was diagnosed using a comprehensive battery of standardized neuropsychological tests.
Results: HIV+ patients had a median age of 36 years, 91% were seroconverters (median window of 1.2 years), had a median duration of HIV of 5 years, had a CD4 nadir of 319, had current CD4 of 546 cells/mm(3), and 64% were on highly active antiretroviral therapy (initiated 1.3 years after diagnosis at a median CD4 of 333 cells/mm(3)). NCI was diagnosed among 38 (19%, 95% confidence interval 14%-25%) HIV+ patients, with a similar prevalence of NCI among earlier and later stage patients (18% vs 20%, p = 0.72). The prevalence of NCI among HIV+ patients was similar to HIV- patients.
Conclusions: HIV+ patients diagnosed and managed early during the course of HIV infection had a low prevalence of NCI, comparable to matched HIV-uninfected persons. Early recognition and management of HIV infection may be important in limiting neurocognitive impairment. Neurology (R) 2013;80:371-379

AB Modulation-doped quantum wells (QWs) of GaSb clad by AlAsSb were grown by molecular beam epitaxy on InP substrates. By virtue of quantum confinement and compressive strain of the GaSb, the heavy- and light-hole valence bands in the well are split and the hole mobility is thereby significantly enhanced. Room-temperature Hall mobilities as high as 1200-1500 cm(2)/V s were achieved for 5-10 nm QWs and biaxial strains of 1-3%. This contrasts with earlier work on GaSb/AlGaAsSb QWs on GaAs substrates in which the mobilities were found to fall off above 1% strain. Moreover, unlike in comparable InGaSb and InSb QWs, the high mobilities were maintained out to sheet densities of 3.5 x 10(12)/cm(2). As a result, the sheet resistivities observed in the GaSb/AlAsSb wells reached record levels as low as 1500 Omega/square. Modeling indicates that this performance gain is due to the larger valence band offset of the GaSb QWs and the consequent reduction in scattering because of the better confinement and the lower doping levels needed for a given sheet charge.

AB We present a new catalog of spectroscopically confirmed white dwarf stars from the Sloan Digital Sky Survey (SDSS) Data Release 7 spectroscopic catalog. We find 20,407 white dwarf spectra, representing 19,712 stars, and provide atmospheric model fits to 14,120 DA and 1011 DB white dwarf spectra from 12,843 and 923 stars, respectively. These numbers represent more than a factor of two increase in the total number of white dwarf stars from the previous SDSS white dwarf catalogs based on DR4 data. Our distribution of subtypes varies from previous catalogs due to our more conservative, manual classifications of each star in our catalog, supplementing our automatic fits. In particular, we find a large number of magnetic white dwarf stars whose small Zeeman splittings mimic increased Stark broadening that would otherwise result in an overestimated log g if fit as a non-magnetic white dwarf. We calculate mean DA and DB masses for our clean, non-magnetic sample and find the DB mean mass is statistically larger than that for the DAs.

AB Recent work has developed a new framework for the impact of vertical wind shear on the intensity evolution of tropical cyclones. A focus of this framework is on the frustration of the tropical cyclone's power machine by shear-induced, persistent downdrafts that flush relatively cool and dry (lower equivalent potential temperature, theta(e)) air into the storm's inflow layer. These previous results have been based on idealised numerical experiments for which we have deliberately chosen a simple set of physical parameterisations. Before efforts are undertaken to test the proposed framework with real atmospheric data, we assess here the robustness of our previous results in a more realistic and representative experimental setup by surveying and diagnosing five additional numerical experiments. The modifications of the experimental setup comprise the values of the exchange coefficients of surface heat and momentum fluxes, the inclusion of experiments with ice microphysics, and the consideration of weaker, but still mature tropical cyclones.
In all experiments, the depression of the inflow layer theta(e) values is significant and all tropical cyclones exhibit the same general structural changes when interacting with the imposed vertical wind shear. Tropical cyclones in which strong downdrafts occur more frequently exhibit a more pronounced depression of inflow layer theta(e) outside of the eyewall in our experiments. The magnitude of the theta(e) depression underneath the eyewall early after shear is imposed in our experiments correlates well with the magnitude of the ensuing weakening of the respective tropical cyclone. Based on the evidence presented, it is concluded that the newly proposed framework is a robust description of intensity modification in our suite of experiments.

AB Conventional scaling for steady-fin or flapping-fin forces in a uniform flow is by definition incompatible with the scaling that has been developed for hovering flapping fins. Most flapping-fin-based vehicles will need to operate in all three operating regimes: fixed fin in cruise, flapping in cruise, and flapping in hover. A unified normalization scheme is proposed to enable smooth and optimal transition of the scaling rules between these regimes. A rigid flapping foil was experimentally tested in a towing tank. The generated side force was found to be a function only of the fin bias angle and the vector magnitude of the inflow and flapping speeds. The thrust was found to be a function of the ratio of fin flapping speed to total speed magnitude in addition to bias and speed magnitude. As an application of this scaling, an algorithm to synthesize the foil motion parameters for a desired thrust and side force regardless of vehicle speed was tested experimentally on a single foil in real time.

AB Many marine civil engineering applications require knowledge and understanding of the behavior and strength properties of soft cohesive marine sediments under high strain-rate conditions, typically encountered during impact penetration events of sediment probes and other objects as a result of free fall through the water column. To investigate these effects, a series of variable rotational rate vane shear tests was performed on a sample of Gulf of Mexico marine mud, using a precision rheometer and spanning the rotational rate range of 0.25-1000 r/min. A wide range of water contents from 55% to 95% (liquidity index: 1.5-3.3) was examined as a primary influence on the response of a particular saturated silty clay material. Nonlinearities in the behavior of this soil were analyzed, and applicability and precision of various models were examined. A modified rate equation is suggested yielding good correlation with experimental data at all water contents and all rotational rates explored. A testing schedule for a complete material constant derivation procedure is outlined.

AB In this paper, the design of an electronic circuit for harvesting energy trickling from benthic sources and the long-term performance in powering sensors and devices in a littoral tidal basin are considered. The process has to contend with the randomness, diurnal variations, and low levels and voltages in available energy compared to what is required by oceanographic sensors. The system has two components: a circuit for conditioning the power and a large area electrode array in a littoral basin. The circuit has two stages and is able to overcome the leaks in capacitors used to store the power; the energy is stored first in a small capacitor and then in a large one so that voltages compatible with sensors are produced. The footprint of the anode is 10 m(2) and is inserted into the sediment and the cathode resides in the salt water above the sediment. Several different sensors and actuators have been autonomously powered by the stored energy (4.2 kJ at 12 V). A beacon and an underwater acoustic sensor (5 h of activation of combined hydrophone and three-axis accelerometer sensors, every 40 h; duty cycle has been doubled with recent improvements) have been powered over one to two months. Also, in-water propulsion (for 165 s at a time) of a 25-W biorobotic flapping fin propulsor has been achieved. The system is suitable primarily for powering sensors. It has been operated for more than three years at useful duty cycles, indicating sustainability for autonomous usage.

AB This paper presents a feasibility study of underwater communications between buried sensor network nodes. To investigate this problem, two experiments have been conducted: where some sensor nodes are buried in the sediment, and where all sensor nodes are buried in the sediment. The orthogonal frequency-division multiplexing (OFDM) communications have been chosen to test underwater communications because of its unique strength in handling transmissions over long dispersive channels. Since the existing OFDM schemes for underwater communications are designed to achieve high data rate communications within the water column and are not adequate for communications between sensors placed on the ocean floor, a new low-complexity OFDM receiver has been proposed. The proposed receiver performs frame-by-frame channel estimation, residual phase tracking, diversity combining, and data demodulation. This approach is adopted because of its effectiveness in applications with very fast varying channels and a large number of propagation paths. It is demonstrated that the error-free performance can be achieved between buried sensors using the proposed OFDM receiver.

AB Multifunctional structure-battery composites were developed using fiber reinforced marine composites for structure function and rechargeable lithium-ion cells for energy storage and structure function. Laminate, sandwich, and modular beam configurations were fabricated and tested to determine flexural stiffness and strength, energy storage capacity versus discharge rate, and buoyancy (density). The structure-battery composites exhibited higher flexural stiffness but lower strength than equivalent unifunctional designs, energy storage capacities between 40 and 60 Wh/L, and buoyancies bracketing the unifunctional specimen values. Issues requiring further attention include: improved bending strength, simplified fabrication, reversible attachments for modular components, electrical wiring and connections, and battery management circuitry.

AB Objective: To examine the association between postconcussive symptoms and mild traumatic brain injury (MTBI) among combat veterans while adjusting for posttraumatic stress disorder (PTSD) and depression. Patients: Military personnel with provider-diagnosed MTBI (n = 334) or nonhead injury (n = 658) were identified from the Expeditionary Medical Encounter Database. Main Outcome Measures: Post-Deployment Health Assessments and Re-Assessments were used to examine postconcussive symptoms and self-rated health. Results: Personnel with MTBI were more likely to report headache (odds ratio [OR] = 3.37; 95% confidence interval [CI] = 2.19-5.17), back pain (OR = 1.79; 95% CI = 1.23-2.60), memory problems (OR = 1.86; 95% CI = 1.20-2.88), tinnitus (OR = 1.63; 95% CI = 1.10-2.41), and dizziness (OR = 2.13; 95% CI = 1.06-4.29) compared with those with non-head injuries. Among those with MTBI, self-reported decline in health was associated with memory problems (OR = 5.07; 95% CI = 2.56-10.02) and dizziness (OR = 10.60; 95% CI = 3.48-32.27). Conclusions: Mild traumatic brain injury is associated with reports of negative health consequences among combat veterans even when accounting for co-occurring psychological morbidity. The identification of postconcussive symptoms related to declines in a service member's self-rated health may be important in targeting and prioritizing clinical interventions.

AB Background: Maternal depression is a common condition among new mothers that can be associated with poor maternal health and negative consequences on infant health. Little research has been conducted to examine maternal depression, especially among military mothers, where unique conditions often exist. Using data from a large military cohort, this study prospectively examined the relationship between deployment experience before and after childbirth and maternal depression among U.S. servicewomen.
Methods: The study included 1,660 female Millennium Cohort participants who gave birth during active duty service and completed baseline and follow-up questionnaires between 2001 and 2008. Maternal depression was assessed at follow-up using Primary Care Evaluation of Mental Disorders Patient Health Questionnaire criteria.
Results: Deployment before childbirth, regardless of combat experience, and deployment without combat experience after childbirth did not increase the risk of maternal depression. Women who deployed and reported combat experience after childbirth were at increased risk for maternal depression compared with nondeployed women who gave birth (adjusted odds ratio [OR] 2.01, 95% confidence interval [CI] 1.17-3.43). Among the subgroup of female combat deployers, however, women who gave birth did not have a significantly increased risk for depression compared with those who did not give birth.
Conclusions: Military women who deployed with combatlike experiences after childbirth were at increased risk for postdeployment maternal depression. The risk, however, appeared primarily related to combat rather than childbirth-related experiences.

AB Topsoil from arid regions is the main source of dust clouds that move through the earth's atmosphere, and microbial communities within these soils can survive long-range dispersion. Microbial abundance and chemical composition were analyzed in topsoil from various desert regions. Statistical analyses showed that microbial direct counts were strongly positively correlated with calcium concentrations and negatively correlated with silicon concentrations. While variance between deserts was expected, it was interesting to note differences between sample sites within a given desert region, illustrating the 'patchy' nature of microbial communities in desert environments.

By employing the optoelectronic reciprocity relation, the irradiation-induced degradation in the J-V characteristics of all individual subcells and their underlying diode saturation parameters is derived. Also, the dependence of the solar cell irradiation response on the position of the irradiation-induced non-radiative recombination centers within the cell active region, i.e., the quasi-neutral regions and the space charge region, is discussed.

AB Biogenic gas has a wide range of energy applications from being used as a source for crude bio-oil components to direct ignition for heating. The current study describes the use of biogenic gases from Clostridium acetobutylicum for a new application-renewable ballast regeneration for autonomous underwater devices. Uninterrupted (continuous) and blocked flow (pressurization) experiments were performed to determine the overall biogas composition and total volume generated from a semirigid gelatinous matrix. For stopped flow experiments, C. acetobutylicum generated a maximum pressure of 55 psi over 48 h composed of 60 % hydrogen gas when inoculated in a 5 % agar (w/v) support with 5 % glucose (w/v) in the matrix. Typical pressures over 24 h at 318 K ranged from 10 to 33 psi. These blocked flow experiments show for the first time the use of microbial gas production as a way to repressurize gas cylinders. Continuous flow experiments successfully demonstrated how to deliver biogas to an open ballast control configuration for deployable underwater platforms. This study is a starting point for engineering and microbiology investigations of biogas which will advance the integration of biology within autonomous systems.

AB The aim of this article was to determine the effect of cirrhosis on mortality in thermally injured adult patients. We conducted a retrospective review of patients admitted to our burn center during 2003 to 2010. Eight hundred eight patients were included in this study, of whom 24 had the diagnosis of cirrhosis established from electronic medical records and/or autopsy reports. The mortality rate for the cirrhotic patients was 50%, and for the noncirrhotic patients it was 14.8%. On logistic regression, age (odds ratio [OR], 1.08; confidence interval [CI], 1.06-1.10), TBSA (OR, 1.08; CI, 1.06-1.10), inhalation injury (OR, 3.17, CI, 1.61-6.25), and cirrhosis (OR, 8.78; CI, 2.97-25.98) had independent effects on mortality. Of the 24 cirrhotic patients in this study, the admission Model for End-Stage Liver Disease score for the patients who survived hospitalization was 12.1 +/- 4.0, and for the patients who died it was 13.8 +/- 6.0 (P = .4). When comparing patients with 10 to 50% TBSA burn, the mortality rate for cirrhotic patients was 83.3% (10/12), and for the noncirrhotic patients it was only 12.7% (50/394), P < .0001. Adults with cirrhosis are rarely able to survive burn injuries > 10% TBSA. Although we did not detect a significant association between admission Model for End-Stage Liver Disease score and death, the presence of cirrhosis is a high premorbid contributor and, therefore, new strategies are needed to improve outcomes.

AB Unique sets of Electra Doppler Radar (ELDORA) observations in both developing and nondeveloping tropical disturbances in the western North Pacific are used to retrieve latent heating and cooling rates. During the reintensification of Sinlaku, maximum heating rates of about 80 K h(-1) are diagnosed in the upper troposphere in the region of a strong updraft and maximum cooling rates of about -45 K h(-1) are diagnosed in the lower troposphere in the region of a strong convective-scale downdraft. The southern convective burst in the pre-Nuri mission had a lower-tropospheric maximum in latent heating that was a more favorable condition for tropical cyclone formation than was the upper-tropospheric maximum in heating and the lower-tropospheric maximum in cooling in the northern convective burst. Two nondeveloping tropical disturbances had deeper layers of more uniform heating and of cooling rates, and some evidence of more shallow cloud tops, that distinguished them from the developing cases.
Although the Shige et al. Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) algorithm was only intended to be applied over large areas on longer time scales, the PR-derived latent heating profiles were compared with the ELDORA-derived profiles to reveal important mesoscale effects. Because all six cases indicated near-zero cooling rates, a new TRMM PR algorithm should be developed that would include the effects of saturated convective-scale downdrafts in tropical mesoscale convective systems (MCSs). Production of a legacy TRMMPR dataset with this improvement would be useful for diagnosing tropical cyclone formation dating back to 1998, and for specifying initial and validation conditions for numerical models in the tropics.

AB Latent heating and cooling rates have a critical role in predicting tropical cyclone formation and intensification. In a prior study, Park and Elsberry estimated the latent heating and cooling rates from aircraft Doppler radar [Electra Doppler Radar (ELDORA)] observations for two developing and two nondeveloping tropical disturbances during the Tropical Cyclone Structure 2008 (TCS-08) field experiment. In this study, equivalent retrievals of heating rates from two mesoscale models with 1-km resolution are calculated with the same radar thermodynamic retrieval. Contoured frequency altitude diagrams and vertical profiles of the net latent heating rates from the model are compared with the ELDORA-retrieved rates in similar cloud-cluster regions relative to the center of circulation.
In both the developing and nondeveloping cases, the radar-equivalent retrievals from the two models tend to overestimate heating for less frequently occurring, intense convective cells that contribute to positive vorticity generation and spinup in the lower troposphere. The model maximum cooling rates are consistently smaller in magnitude than the heating maxima for the nondeveloping cases as well as the developing cases. Whereas in the model the cooling rates are predominantly associated with melting processes, the effects of evaporative cooling are underestimated in convective downdraft regions and at upper levels. Because of the net warming of the columns, the models tend to overintensify the lower-tropospheric circulations if these intense convective cells are close to the circulation center. Improvements in the model physical process representations are required to realistically represent the evaporative cooling effects.

AB A suite of idealized mesoscale model simulations are conducted to examine the dynamic pathway to the genesis of short-scale, moist baroclinic disturbances. It is shown that in an initially subsaturated environment, two distinct stages of development are necessary before a preexisting surface-concentrated, warm-core vortex can begin to amplify. The first stage, termed environmental preconditioning, involves the moistening of the lower atmosphere via the transport of relatively high equivalent potential temperature air into the immediate environment of the translating vortex.
The second stage results from continuous cloud diabatic processes and it involves the emergence of a low-level positive potential vorticity (PV) anomaly with some evidence of a further, more diffuse, negative PV anomaly at higher elevations. The PV structure is characteristic of a diabatic Rossby vortex (DRV). The disturbance does not begin to amplify until the magnitude and coherence of the low-level PV structure allows for the sufficient production of eddy available potential energy through diabatic processes to overcome frictional dissipation, and this necessitates forced convection for a finite period of time. A comparison of the simulated disturbance structure with observed DRVs lends credence to the idealized model results.
Furthermore, the simulations facilitate the identification of an amplitude threshold for DRV genesis that is defined as a function of both environmental parameters (baroclinicity and moisture content) and the strength of an initial disturbance. In particular, if, given a background environment, the amplitude of an initial disturbance is not sufficiently large, frictional processes will inhibit the genesis of a growing disturbance within a realistic time frame.

AB Quantum transport calculations show that a transport gap approximately E-g = 2hv(F)/W can be engineered in graphene using two parallel transport barriers, separated by W, extended along the zigzag direction. The barriers, modeled by chemically decorated observed line defects, create confinement and resonance bands tracing the bands in zigzag nanoribbons. The resonance bands terminate at the dimensional crossover, where the states become boundary-localized, leaving the transport gap. The structure also allows for nearly perfect valley polarization.

DE RDE; Hydrocarbon; Simulation; Continuous detonation
AB Rotating detonation engines (RDE's) represent a logical step from pulsed detonation engine concepts to a continuous detonation engine concept for obtaining propulsion from the high efficiency detonation cycle. The hydrogen/air and hydrogen/oxygen RDE concepts have been most extensively studied, however, being able to use hydrocarbon fuels is essential for practical RDE's. The current paper extends our hydrogen/air model to hydrocarbon fuels with both air and pure oxygen as the oxidizer. Before beginning the RDE calculations, several detonation tube results are summarized showing the ability of the code to reproduce the correct detonation velocity and CJ properties. In addition, a calculation capturing the expected irregular detonation cell patterns of ethylene/air is also shown. To do the full range of fuels and oxidizers, we found the use of temperature-dependent thermodynamic properties to be essential, especially for hydrocarbon/oxygen mixtures. The overall results for air-breathing RDE's with hydrocarbons ranged from 1990 to 2540 s, while in pure oxygen mode the specific impulse varied from 700 to 1070 s. These results were between 85% and 89% of the expected ideal detonation cycle results, and are in line with previous hydrogen/air estimates from our previous work. We conclude from this that hydrocarbon RDE's are viable and that the basic flow-field patterns and behaviors are very similar to the hydrogen/air cases detailed previously.

AB Time-dependent, multidimensional simulations of unstable propagating detonations were performed using a detailed thermochemical reaction model for a stoichiometric argon-diluted hydrogen-oxygen mixture at low pressures and a hydrogen-air mixture at atmospheric pressure. Detonation cells computed for the low-pressure, dilute H-2-O-2-Ar systems were regular in shape, and their sizes compared reasonably well with experimental observations. The computed H-2-air cells at atmospheric conditions were qualitatively different from those observed in experiments, and their widths range from less than 1 mm to nearly 5 mm with multilevel hierarchal structures. The effective activation energy of the H-2-air mixture, based on constant-volume ignition delay times computed using the detailed thermochemical model, varies between 5 and 40 over the range of post-shock temperatures and pressures in the simulations and is, on average, significantly larger than expected based on the regularity of experimental cellular patterns. Analysis of the simulations suggests that vibrational relaxation of the gas molecules, a process which is ignored when calibrating detailed chemical reaction models, occurs on time scales similar to the ignition delay times for the detonations and may be a source of discrepancy between numerical and experimental results.

AB A substantial portion of the atmospheric particle budget is of biological origin (human and animal dander, plant and insect debris, etc.). These bioaerosols can be considered information-rich packets of biochemical data specific to the organism of origin. In this study, bioaerosol samples from various indoor environments were analyzed to create identifiable patterns attributable to a source level of occupation. Air samples were collected from environments representative of human high-traffic- and low-traffic indoor spaces along with direct human skin sampling. In all settings, total suspended particulate matter was collected and the total aerosol protein concentration ranged from 0.03 to 1.2 mu g/m(3). High performance liquid chromatography was chosen as a standard analysis technique for the examination of aqueous aerosol extracts to distinguish signatures of occupation compared to environmental background. The results of this study suggest that bioaerosol "fingerprinting" is possible with the two test environments being distinguishable at a 97 % confidence interval.

AB FLAGG SY, REGIS DP, PETERSEN K, MAHON RT. Interrupted oxygen prebreathing and decompression outcomes in swine. Aviat Space Environ Med 2013; 84:12-6. Background: Rescue from a disabled submarine may result in substantial risk for severe decompression sickness (DCS) among survivors. Oxygen prebreathe (OPB) before rapid decompression has been shown to significantly reduce risk or delay onset for severe DCS in animals. However, the duration of this benefit remains unknown and might even be lost if a delay between the prebreathe period to initiation of recompression therapy allows for nitrogen reaccumulation. Methods: We hypothesized that the benefit of OPB would be lost following subsequent periods of air interruption in a 70-kg swine saturation model. Following OPB of 45 or 60 min with varying periods (30, 45, 60 min) of air interruption, 61 swine exposed to 2.7 ATA for 22 h were rapidly decompressed. Swine without OPB served as negative controls and swine treated with 45 min of OPB without air interruption served as positive controls. Results: Comparing experimental groups for Type II DCS incidence showed OPB120/60 being the only experimental group (11%) statistically different than the negative control group OPB0 (80%). Log rank tests comparing Type II DCS free survival only showed statistically significant differences for OPB45/60 compared to positive control group OPB45, while, more importantly, demonstrating a significant difference for OPB120/60 compared to that approximated for OPB45, indicating a significant reversal of the air interruption effects with longer OPB on Type II DCS disease free survival. Discussion: Based on these findings we concluded that the protective effects of OPB against severe DCS are reduced with increasing periods of air interruption.

AB ORSELLO CA, PHILLIPS AS, RICE GM. Height and in-flight low back pain association among military helicopter pilots. Aviat Space Environ Med 2013; 84:32-7. Introduction: Low back pain (LBP) among helicopter pilots is a well-recognized problem, with prevalence ranging from 61 to over 80%. Studies indicate association with total flight hour (TFH) exposure and lack of association with height or body mass index (BMI); however, those that have excluded pilots with back injuries unrelated to flying are limited. Methods: Surveyed regarding LBP were 1028 U.S. Navy helicopter pilots. Of the 648 (63%) respondents, 83 pilots, or 12.9%, who reported nonflying related back injuries and those without necessary data were excluded, yielding N = 554. Case-control analysis was performed with logistic regression for height, BMI, and TFH on significant LBP (defined as >30% of each flight) presence versus absence with Chi-square on the median split of each and ANOVA to include airframes. Results: Height was a positive predictor for significant LBP among all subjects (OR: 1.7), with the strongest association among male pilots (OR: 2.1). BMI, THF, and airframe (H-60, TH-57, H-53, and H-46) were not associated. Discussion: These results imply that ergonomic stressors that adversely impact lumbar symmetry may be a predominant factor in LBP during flight. Significant prevalence rates may persist in the absence of design enhancements that mitigate these stressors. Height was a significant predictor for in-flight LBP among U.S. Navy helicopter pilots studied and BMI, TFHs, and airframe were not. For every 1 '' increase among male pilot height values, the odds of experiencing significant LBP in flight increased by 9.3%, with those equal/taller than median (71 in.) having over twice the odds compared with those shorter. Keywords: lumbar spine, low back pain, helicopter, predictors, military.

To mitigate an onslaught from airborne anthrax spores that are maliciously disseminated, it is of paramount importance to develop a rapid-response anthrax vaccine that can be mass administered by nonmedical personnel during a crisis. We report here that intranasal instillation of a nonreplicating adenovirus vector encoding B. anthracis protective antigen could confer rapid and sustained protection against inhalation anthrax in mice in a single-dose regimen in the presence of preexisting adenovirus immunity. The potency of the vaccine was greatly enhanced when codons of the antigen gene were optimized to match the tRNA pool found in human cells. In addition, an adenovirus vector encoding lethal factor can confer partial protection against inhalation anthrax and might be coadministered with a protective antigen-based vaccine.

AB Human health depends on reliable access to safe drinking water, but in many developing countries only a limited number of wells and boreholes are available. Many of these water resources are contaminated with biological or chemical pollutants. The goal of this study was to examine water access and quality in urban Bo, Sierra Leone. A health census and community mapping project in one neighborhood in Bo identified the 36 water sources used by the community. A water sample was taken from each water source and tested for a variety of microbiological and physicochemical substances. Only 38.9% of the water sources met World Health Organization (WHO) microbial safety requirements based on fecal coliform levels. Physiochemical analysis indicated that the majority (91.7%) of the water sources met the requirements set by the WHO. In combination, 25% of these water resources met safe drinking water criteria. No variables associated with wells were statistically significant predictors of contamination. This study indicated that fecal contamination is the greatest health risk associated with drinking water. There is a need to raise hygiene awareness and implement inexpensive methods to reduce fecal contamination and improve drinking water safety in Bo, Sierra Leone.

ID PIPELINES; DYNAMICS; BUBBLE; WATER
AB The basic physics of the underwater implosion of metal tubes is studied using small scale experiments and finite element simulations. A series of underwater implosion experiments have been conducted with thin-wall aluminum alloy 6061-T6 tubes. The nominal tube dimensions are 2.54 cm outside diameter and 30.48 cm length. Two cylinders collapsed at their natural buckling pressure of 6895 kPa gauge pressure (1000 psig). Two additional cylinders were caused to implode at 6205 kPa gauge pressure (900 psig) using an initiator mechanism. Each of the four cylinders failed with a mode 2 shape (collapsed shape is flat with two lobes). The near field pressure time-history in the water is measured at a radial distance of 10.16 cm (4in.) from the centerline at three points along the cylinder's length. The pressure time-histories show very similar behavior between the cylinders which buckled naturally and those which were mechanically initiated at 90% of the buckling pressure. To aid in understanding the physical implosion phenomena, a computational model is developed with a fluid-structure-interaction finite element code (DYSMAS). This model is validated against the experimental data, and it is used to explain the features of the implosion pressure pulse and how it is physically created. [DOI: 10.1115/1.4006944]

ID GAUSSIAN-BASIS SETS; TERAHERTZ SPECTROSCOPY; EXPLOSIVES; SPECTRUM
AB The need for better detection of explosive devices has imposed a necessity for determining the dielectric response properties of energetic materials with respect to electromagnetic wave excitation. Among the range of different frequencies for electromagnetic excitation, the THz frequency range is of particular interest because of its nondestructive nature. The present study is based on significant progress in density functional theory (DFT), and associated software technology, which is sufficiently mature for the determination of dielectric response functions, and actually provides complementary information to that obtained from experiment. This point is further demonstrated in this study by calculations of ground state resonance structure associated with water complexes of the high explosive beta-HMX using DFT, which is for the construction of parameterized dielectric response functions for excitation by electromagnetic waves at frequencies within the THz range. These dielectric functions provide for different types of analyses concerning the dielectric response of explosives. In particular, these dielectric response functions provide quantitative initial estimates of spectral response features for subsequent adjustment with respect to additional information such as laboratory measurements and other types of theory based calculations. With respect to qualitative analysis, these spectra provide for the molecular level interpretation of response structure. The DFT software GAUSSIAN was used for the calculations of ground state resonance structure presented here.

AB This work concerns the development of field directionality mapping algorithms for short acoustic arrays on mobile maneuverable platforms that avoid the left/right ambiguities and endfire resolution degradation common to longer non-maneuverable line arrays. In this paper, it is shown that short maneuverable arrays can achieve a high fraction of usable bearing space for target detection in interference-dominated scenarios, despite their lower array gain against diffuse background noise. Two narrowband techniques are presented which use the expectation-maximization maximum likelihood algorithm under different models of the time-varying field directionality. The first, derivative based maximum likelihood, uses a deterministic model while the second, recursive Bayes maximum likelihood, uses a stochastic model for the time-varying spatial spectrum. In addition, a broadband extension is introduced that incorporates temporal spectral knowledge to suppress ambiguities when the average sensor array spacing is greater than a half-wavelength. Dynamic multi-source simulations demonstrate the ability of a short, maneuvering array to reduce array ambiguities and spatial grating lobes in an interference dominated environment. Monte Carlo evaluation of receiver operating characteristics is used to evaluate the improvement in source detection achieved by the proposed methods versus conventional broadband beamforming.

AB The vast majority of animal vocalizations contain multiple frequency modulated (FM) components with varying amounts of non-linear modulation and harmonic instability. This is especially true of biosonar sounds where precise time-frequency templates are essential for neural information processing of echoes. Understanding the dynamic waveform design by bats and other echolocating animals may help to improve the efficacy of man-made sonar through biomimetic design. Bats are known to adapt their call structure based on the echolocation task, proximity to nearby objects, and density of acoustic clutter. To interpret the significance of these changes, a method was developed for component separation and analysis of biosonar waveforms. Techniques for imaging in the time-frequency plane are typically limited due to the uncertainty principle and interference cross terms. This problem is addressed by extending the use of the fractional Fourier transform to isolate each non-linear component for separate analysis. Once separated, empirical mode decomposition can be used to further examine each component. The Hilbert transform may then successfully extract detailed time-frequency information from each isolated component. This multi-component analysis method is applied to the sonar signals of four species of bats recorded in-flight by radiotelemetry along with a comparison of other common time-frequency representations.

AB Objective: Reintervention rates after repair of abdominal aortic aneurysm (AAA) are higher for endovascular repair (EVAR) than for open repair, mostly due to treatment for endoleaks, whereas open surgical operations for bowel obstruction and abdominal hernias are higher after open repair. However, readmission rates after EVAR or open repair for nonoperative conditions and complications that do not require an intervention are not well documented. We sought to determine reasons for all-cause readmissions within the first year after open repair and EVAR.
Methods: Patients who underwent elective AAA repair in California during a 6-year period were identified from the Health Care and Utilization Project State Inpatient Database. All patients who had a readmission in California <= 1 year of their index procedure were included for evaluation. Readmission rates and primary and secondary diagnoses associated with each readmission were analyzed and recorded.
Results: From 2003 to 2008, there were 15,736 operations for elective AAA repair, comprising 9356 EVARs (60%) and 6380 open repairs (40%). At 1 year postoperatively, the readmission rate was 52.1% after open repair and 55.4% after EVAR (P = .0003). The three most common principle diagnoses associated with readmission after any type of AAA repair were failure to thrive, cardiac issues, and infection. When stratified by repair type, patients who underwent open repair were more likely to be readmitted with primary diagnoses associated with failure to thrive, cardiac complications, and infection compared with EVAR (all P < .001). Those who underwent EVAR were more likely, however, to be readmitted with primary diagnoses of device-related complications (P = .05), cardiac complications, and infection.
Conclusions: Total readmission rates within 1 year after elective AAA repair are greater after EVAR than after open repair. Reasons for readmission vary between the two cohorts but are related to the magnitude of open surgery after open repair, device issues after EVAR, and the usual cardiac and infectious complications after either intervention. Systems-based analysis of these causes of readmission can potentially improve patient expectations and care after elective aneurysm repair. (J Vasc Surg 2013;57:89-95.)

AB Viruses from the Alphavirus genus are responsible for numerous arboviral diseases impacting human health throughout the world. Confirmation of acute alphavirus infection is based on viral isolation, identification of viral RNA, or a fourfold or greater increase in antibody titers between acute and convalescent samples. In convalescence, the specificity of antibodies to an alphavirus may be confirmed by plaque reduction neutralization test. To identify the best method for alphavirus and neutralizing antibody recognition, the standard solid method using a cell monolayer overlay with 0.4% agarose and the semisolid method using a cell suspension overlay with 0.6% carboxymethyl cellulose (CMC) overlay were evaluated. Mayaro virus, Una virus, Venezuelan equine encephalitis virus (VEEV), and Western equine encephalitis virus (WEEV) were selected to be tested by both methods. The results indicate that the solid method showed consistently greater sensitivity than the semisolid method. Also, a "semisolid-variant method" using a 0.6% CMC overlay on a cell monolayer was assayed for virus titration. This method provided the same sensitivity as the solid method for VEEV and also had greater sensitivity for WEEV titration. Modifications in plaque assay conditions affect significantly results and therefore evaluation of the performance of each new assay is needed. Published by Elsevier B.V.

AB Study Objectives: Military members screening positive for blast-related traumatic brain injury (TBI) may subsequently screen positive for posttraumatic stress disorder (PTSD) or depression. The role of sleep as a mediating factor in the development of mental health symptoms was explored.
Design: Prospective study with symptoms evaluated at two time points.
Setting: Postdeployment service in Iraq, Afghanistan, or Kuwait during 2008 and 2009.
Participants: There were 29,640 US Navy and Marine Corps men (29,019 who did not screen positive for PTSD at baseline, 27,702 who did not screen positive for depression at baseline, and 27,320 who did not screen positive at baseline for either condition).
Measurements and Results: After controlling for sleep problems, the adjusted odds of receiving a positive PTSD screening at follow-up decreased from 1.61 (95% confidence interval [CI] 1.21-2.14) to 1.32 (95% CI 0.99-1.77) for a subject screening positive for TBI relative to a subject screening negative, suggesting that sleep problems mediated 26% of TBI's effect on development of PTSD. Likewise, after controlling for sleep problems, the adjusted odds of receiving a positive depression screening decreased from 1.41 (95% CI 1.11-1.80) to 1.15 (95% CI 0.90-1.47), suggesting that sleep problems mediated 41% of TBI's effect on development of depression. Results were similar for those with either PTSD or depression (37% mediated).
Conclusions: These results suggest that sleep problems mediate the effect of a positive TBI screening on the development of mental health disorders, and sleep problems may be an early indicator of risk for PTSD or depression.

AB We report experimental infection and transmission of Leishmania tropica (Wright), by the blood-feeding sand fly Phlebotomus duboscqi (Neveu-Lemaire). Groups of laboratory-reared female sand flies that fed "naturally" on L tropica-infected hamsters, or artificially, via membrane feeding device, on a suspension of L tropica amastigotes, were dissected at progressive time points post-feeding. Acquisition, retention and development of L tropica through procyclic, nectomonad, and leptomonad stages to the infective metacyclic promastigote stage, and anterior progression of the parasites from abdominal midgut blood-meal to the thoracic midgut were demonstrated in both groups. Membrane feeding on the concentrated amastigote suspension led to metacyclic promastigote infections in 60% of sand flies, whereas only 3% of P. duboscqi that fed naturally on an infected hamster developed metacyclics. Sand flies from both groups re-fed on naive hamsters, but despite infections in 25-50% of membrane-fed and 2-3.5% of naturally fed flies, no skin lesions developed in the hamsters. After four months of observation these animals were euthanized and necropsied. Screening of the organs and tissue by polymerase cinain reaction (PCR) that targeted the small subunit RNA gene, amplified generic Leishmania DNA from liver, spleen, bone marrow, and blood, but only from hamsters bitten by membrane-infected P. duboscqi. These results are notable in demonstrating the ability of P. duboscqi, originating from Kenya, to acquire, retain, develop, and transmit a Turkish strain of L tropica originally isolated from a human case of cutaneous leishmaniasis. This marks the first demonstration of complete development and transmission of L tropica by a member of the Phlebotomus subgenus of sand flies. Published by Elsevier B.V.

AB Background. Influenza is a significant cause of morbidity, and vaccination is the preferred preventive strategy. Data regarding the preferred influenza vaccine type among adults are limited.
Methods. The effectiveness of 2 currently available influenza vaccines LAIV and TIV in preventing influenza-like illness (ILI) was compared among US military members (aged 18-49 years) during 3 consecutive influenza seasons (2006-2009). ILI, influenza, and pneumonia events post-vaccination were compared between vaccine types using Cox proportional hazard models adjusted for sociodemographic factors, occupation, and geographic area.
Results. A total of 41 670 vaccination events were evaluated, including 28 929 during 2 "well-matched" seasons (2006-2007 and 2008-2009: LAIV n = 22 734, TIV n = 6195) and 12 741 during a suboptimally matched season due to mild antigenic drift (2007-2008: LAIV n = 9447, TIV n = 3294). ILI crude incidence rates for LAIV and TIV were 139 and 127 cases per 1000 person-seasons for the well-matched seasons, respectively, and 150 and 165 cases per 1000 person-seasons for the suboptimally matched season, respectively. In the multivariable models, there were no differences in ILI events by vaccine type (well-matched seasons: hazard ratio [HR], 0.97; 95% confidence interval [CI], .90-1.06; suboptimally matched season: HR, 1.00; 95% CI, .90-1.11). There were also no differences in influenza and/or pneumonia events by vaccine group.
Conclusions. Between 2006 and 2009, TIV and LAIV had similar effectiveness in preventing ILI and influenza/pneumonia events among healthy adults.

TI Changes in Urine Parameters After Desert Exposure: Assessment of Stone
Risk in United States Marines Transiently Exposed to a Desert
Environment
SO JOURNAL OF UROLOGY
LA English
DT Article
DE urolithiasis; desert climate; military personnel
ID SUNLIGHT
AB Purpose: Living in a desert environment has been associated with a higher incidence of kidney stone formation, likely because of concentrated urine output, higher production of vitamin D and genetic predisposition. We determined the changes in urinary parameters after a group of United States Marines temporarily transitioned from a temperate environment to a desert environment.
Materials and Methods: A total of 50 Marines completed a questionnaire and performed 3, 24-hour urine collections before mobilization to the desert, after 30 days in the desert and 2 weeks after returning from the desert.
Results: Daily urine output decreased 68% to 0.52 L despite marked increased fluid intake (17 L per day). Total daily urinary excretion of calcium, uric acid, sodium, magnesium and potassium in the desert decreased by 70%, 41%, 53%, 22% and 36%, respectively. Urinary pH decreased from 6.1 to 5.6 while in the desert, and citrate and oxalate had minimal changes. After their return from the desert, apart from a decrease of 22% in oxalate, there were no statistically significant differences from baseline. While in the desert, relative supersaturation risks of uric acid and sodium urate were increased 153% and 56%, respectively. Brushite relative supersaturation decreased 24%. After their return there was no statistical difference from baseline.
Conclusions: Our findings suggest that the kidneys preserved water and electrolytes while the Marines were subjected to the desert environment. Despite this conservation, relative saturations indicate increased risk of stones in healthy men exposed to a desert environment with rapid resolution upon return.

DT Article
AB The shapes of two wires in a vertical plane with the same starting and ending points are described as complementary curves of descent if beads frictionlessly slide down both of them in the same time, starting from rest. Every analytic curve has a unique complement, except for a cycloid (solution of the brachistochrone problem), which is self complementary. A striking example is a straight wire whose complement is a lemniscate of Bernoulli. Alternatively, the wires can be tracks down which round objects undergo a rolling race. The level of presentation is appropriate for an intermediate undergraduate course in classical mechanics.

AB In this letter, we propose two improvements of the MOD and K-SVD dictionary learning algorithms, by modifying the two main parts of these algorithms-the dictionary update and the sparse coding stages. Our first contribution is a different dictionary-update stage that aims at finding both the dictionary and the representations while keeping the supports intact. The second contribution suggests to leverage the known representations from the previous sparse-coding in the quest for the updated representations. We demonstrate these two ideas in practice and show how they lead to faster training and better quality outcome.

AB Introduction: Kernicterus is a serious but easily preventable disease in newborns that is not well-known even by some health care professionals. This study evaluated a parent guide and poster on kernicterus awareness and prevention generated by the Centers for Disease Control and Prevention. The Extended Parallel Processing Model was used as a framework for creating the interview protocol and analyzing the results.
Method: In-depth interviews were conducted with four parents and six health care personnel of different ethnicities to evaluate the materials. Content for the parent guide and poster was held constant, but photos were varied according to the ethnicity of the baby (white, African American, or Hispanic) and the language in which the interviews were conducted (English and Spanish).
Results: The parent guide was evaluated positively, but reactions to the poster were varied. The consensus was that the poster drew more attention than the pocket guide but lacked sufficient information about what jaundice is or how to treat it, while the pocket guide provided information, especially with regard to efficacy. The Extended Parallel Processing Model claims that when efficacy is equal to or higher than perceived threat, respondents should engage in recommended responses, which was the general finding from these interviews.
Discussion: Recommendations for improvements of the materials are presented. The focus on different ethnicities in the materials was perceived as unnecessary and potentially counter-productive. Both parents and health care professionals mentioned the lack of information regarding treatment. Providing information on the length and effectiveness of treatment for jaundice and kernicterus might increase efficacy in averting the threat in both conditions. J Pediatr Health Care.

AB Large-scale rodent control can help to manage endangered species that are vulnerable to invasive rodent consumption. A 26 ha rodent snap-trap grid was installed in montane forest on Oahu Island, Hawaii, in order to protect endangered snails and plants. To assess the effectiveness of this trapping operation in reducing fruit consumption and seed predation of the endangered Hawaiian lobeliad, Cyanea superba subsp. superba, pre- and post-dispersal C. superba fruit consumption were monitored for 36 plants at the site with rodent control (Kahanahaiki) and 42 plants at an adjacent site without rodent control (Pahole). Over 47 % of all monitored fruit were eaten on the plants at Pahole compared to 4 % at Kahanahaiki. Images captured using motion-sensing cameras suggest that black rats (Rattus rattus) were the only pre-dispersal fruit consumers. To quantify post-dispersal fruit consumption, and to identify the culprit frugivore(s), mature fruit were placed in tracking tunnels positioned on the forest floor and checked daily. At Pahole, all of the fruit were consumed by rats compared to 29 % at Kahanahaiki. Lastly, to determine if rodents from the sites were predators or dispersers of C. superba seed, fruit were fed to captive black rats and house mice (Mus musculus). Black rats consumed entire fruit, killing all the seed, while mice did little damage to the fruit and seed. Therefore, large-scale rat trapping can directly benefit the reproduction of C. superba subsp. superba. Controlling black rats at restoration sites appears integral to the successful restoration of this endangered plant species.

AB An increasing body of evidence reported in the literature indicates a possible role for post-traumatic stress disorder (PTSD) as a cause for cardiovascular disease (CVD). However, mechanistic evidence on the progression of adverse cardiac outcomes in PTSD is lacking. In this review, we examine the potential paths by which CVD could occur in those with PTSD. Dysregulation of the hypothalamic-pituitary-adrenal axis and autonomic nervous dysfunction are commonly observed in PTSD, which in turn leads to a variety of physiological changes potentially damaging to the heart. Increased inflammation, dysfunction of the vascular endothelium, hypercoagulability, and cardiac hyperreactivity all have been noted in patients with PTSD. Altered neurochemistry, most notably increased arginine vasopressin, as well as an increased prevalence of the metabolic syndrome, may also contribute to adverse cardiac outcomes. Although the association between PTSD and physical disease is often complicated by health risk behaviors or comorbid psychiatric conditions, the evidence for a link between PTSD and CVD is substantial. In our examination, we attempt to identify potential cardiac biomarkers that may be useful in detecting increased cardiac risk in patients with PTSD. As research in this area is exceedingly limited, we hope to inspire further research, as there is great potential value in identifying prognostically useful cardiac biomarkers so as to predict and prevent the onset of CVD in patients with PTSD.

AB The military's need to reduce both fuel and battery resupply is a real-time requirement for increasing combat effectiveness and decreasing vulnerability. Mobile photovoltaics (PV) is a technology that can address these needs by leveraging emerging, flexible space PV technology. In this project, the development and production of a semirigid, lightweight, efficient solar blanket with the ability to mount on, or stow in, a backpack and recharge a high-capacity rechargeable lithium-ion battery was undertaken. The 19% efficient blanket consists of a 10 x 3 solar array of 20 cm(2) and single-junction epitaxial lift-off solar cells, which have an efficiency of similar to 22% under AM1.5G illumination. A power-conditioning module was also developed to interface the solar panel to the battery. Thirteen systems were outfitted during a Limited Objective Experiment-1 in February 2012, and based on the results, a second version of the system is in development.

The interdependent roles of heavy-ion and laser-induced upset evaluation coupled with computer-aided investigations of SEE mechanisms and mitigation techniques in this process are shown to enable a significant reduction in SEE sensitivity of the device, while achieving minimal impact on remanufacturing steps.

AB The first ion-induced, time-resolved charge-collection measurements for p-channel AlGaSb/InGaSb field-effect transistors are reported. The transient response reveals two distinct decay regions; a fast initial decay (< 1 ns) followed by a slower decay (> 10 ns). The slow decay is associated with charge enhancement processes, which are explained by electron trapping and de-trapping via deep-level traps located in the AlGaSb barrier material. Charge enhancement effects are reported for different drain and gate bias conditions, and it is found that charge-enhancement effects are suppressed when the gate bias is increased toward depletion. The effects of the bias on the transient response are presented and discussed.

AB Sparse representation is a promising technique for the field of image processing and pattern recognition. It generally exploits over-complete dictionaries which is fixed and known in advance, or learned using training algorithm such as K-SVD. In this paper, we propose a new multimodal image fusion approach based on the sparsity model with local patch dictionaries generated directly from input images. For every location in the image, dictionary is simply constructed with neighboring patches. Experimental results show that the proposed method is efficient and competitive with some existing image fusion methods.

AB This paper focuses on an optimal control problem in which the objective is to minimize the expectation of a cost functional with stochastic parameters. The inclusion of the stochastic parameters in the objective raises new theoretical and computational challenges not present in a standard nonlinear optimal control problem. In this paper, we provide a numerical framework for the solution of this uncertain optimal control problem by taking a sample average approximation approach. An independent random sample is taken from the parameter space, and the expectation is approximated by the sample average. The result is a family of standard nonlinear optimal control problems which can be solved using existing techniques. We provide an optimality function for both the uncertain optimal control problem and its approximation, and show that the approximation based on the sample average approach is consistent in the sense of Polak. We illustrate the approach with a numerical example arising in optimal search for a moving target.

AB The Aegis Combat System [1] is used to protect US Navy vessels from planes and missiles. The computer-based command-and-decision element is the core of the Aegis Combat System. This interface makes the ACS capable of simultaneous operation against almost all kinds of threats. The Aegis Ballistic Missile Defense System program is intended to enable the Aegis system to act in a sea-based ballistic missile defense function, to counter short- and medium-range ballistic missiles of the variety typically employed by a number of potential opponent states. It works by firing a large amount of projectiles at the incoming missiles. Critical to the success of this system are real time accurate estimates of the trajectories of the incoming missiles. This requires filtering of the noisy measurements but what distinguishes it from standard filtering is that we know where the missiles are heading. (If they are not heading toward the ship or the target that the ship is protecting then we don't care about them.) In effect we are interested in filtering a system that has boundary constraints. Hence we consider the problem of filtering a linear system that satisfies boundary conditions rather than initial conditions.

AB Recently it has been proposed that two-dimensional (2D) oversampled received arrays could be used to provide signal-to-external noise ratio (SENR) gains for over-the-horizon radar applications which are strongly externally noise limited. These array configurations can be used to exploit superdirective adaptive beamforming techniques. A key element of the superdirective adaptive beamforming process is the estimation of the array spatial noise covariance matrix. In this paper we propose a parametric covariance modeling technique called aperture varying autoregressive (AVAR) covariance modeling that captures the 2D spatial correlation structure of high-frequency (HF) background noise sampled by an oversampled 2D receive array. The use of this covariance modeling technique can significantly reduce the computational requirements for the inversion of large spatial covariance matrices. Additional gains are achieved via reduced sample support requirements for an N-element 2D receive array.
In this paper we introduce 2D aperture varying autoregressive models AVAR(m, l) that are spatially non-stationary generalizations of traditional autoregressive AR(m) or AR (m, l) techniques. While traditional AR techniques model covariance structure as toeplitz or toeplitz-block-toeplitz, these new AVAR models enforce a banded or doubly banded inverse covariance structure which is more general. The introduced AVAR methods are closely coupled to the oversampled array architecture which in the presence of nearly homogeneous external noise exhibits spatial correlation most strongly amongst closely spaced elements. Therefore the use of these AVAR methods effectively restricts the adaptive beamforming to gains achievable through superdirective beamforming.

AB When a crisis occurs, there is often little time to evaluate the situation and determine how best to respond. We use rapid ethnographic methods centered on the construction of geo-temporally contextualized social and knowledge networks.

AB Reduced performance in Gallium Nitride (GaN)-based high electron mobility transistors (HEMTs) as a result of self-heating has been well-documented. A new approach, termed "gate after diamond," is shown to improve the thermal budget of the deposition process and enable large-area diamond without degrading the gate metal. Nanocrystalline (NCD)-capped devices had 20% lower channel temperature at equivalent power dissipation. Improved electrical characteristics were observed, notably improved on-resistance and breakdown voltage, and reduced gate leakage. Further refinements to the NCD growth process have enabled deposition directly on the GaN surface. Pulsed I-V measurements indicate a comparable passivation effect to conventional SiNX-capped devices.

AB GaN on SiC technology has offered tremendous benefits over existing GaAs-based RF technologies. The high breakdown voltage and current handling capability of GaN HEMTs enable a 10x increase in RF power over conventional GaAs-based devices for the same device size. These benefits translate to dramatically improved performance for military and commercial communications, radar and high-power RF systems. However, despite the high thermal conductivity materials and optimized epitaxial profiles already being used, additional improvement of MMIC performance is limited by thermal constraints. Substrate and near channel thermal resistance is a key thermal bottleneck limiting device compaction and junction temperature reduction. NGAS will report on revolutionary methods being developed to directly integrate high quality, high thermal conductivity diamond materials with more than 4x greater thermal conductivity over existing state-of-the-art GaN on SiC HEMT technology. Reducing temperature in the device channel and surrounding regions is critical for reliable operation, supporting additional device compaction and improving circuit performance.

AB Motivated by some critical observations from field tests, in this paper, we design and implement a Coding based multi-hop Coordinated Reliable Data Transfer (CCRDT) protocol for underwater acoustic networks. CCRDT is based on hop-by-hop reliable data transfer with multi-hop coordination. For the per-hop data transfer, a GF(256) Random Linear Coding scheme and a coding ratio estimation approach are proposed to guarantee the reliability and efficiency of data transfer. In addition, a multi-hop coordination scheme is designed to enable transmission pipelining that allows multiple nodes to transmit simultaneously. By carefully scheduling the transmission of every node, our multi-hop coordination scheme effectively eliminates packet collisions, which further improves the end-to-end throughput. We implement CCRDT on a lab testbed and conducted extensive tests to evaluate its performance. Our results show that CCRDT achieves a higher end-to-end throughput than other existing reliable data transfer protocols which have been implemented in real systems.

AB The IETF is developing an IPv6 Routing Protocol for Low Power and Lossy Networks (RPL) for smart machine-tomachine networks. In this paper, we present a RPL protocol for the mesh based multigateway Advanced Metering Infrastructure (AMI) of the Smart Grid. The multigateway RPL is based on the construction and maintenance of multiple directed acyclic graphs (DAG) that are each rooted at a gateway. The DAGs are constructed using node rank computation. We incorporate an interference based routing metric into the RPL to facilitate rank computation. The interference link metric, based on SINR measurements, is used to construct and maintain DAGs for least interference routing. We will show that our multigateway RPL protocol performs better in terms of packet delivery ratio, delay and throughput when compared to generic routing schemes such as AODV and RPL protocols that use ETX (expected transmission time) as the link metric. We also study the multigateway RPL under link failures to show that high throughput data routing can be achieved.

AB This work deals with the analysis of a novel data processing approach to estimate the local depth in a shallow coastal area starting from X-band radar data. The approach is based on the maximization of the Normalized Scalar Product (NSP) between the measured and the theoretical wave dispersion relations, which embed the dependence on the searched for parameters (current vector and depth). In the present work, we presented an improvement version of NSP approach able to estimate the local depth, which allows to obtain a high resolution spatial map (subpixel) of the investigated area. The performances of the NSP approach is evaluated by comparing the estimated bathymetry with the ground truth provided the multi-beam echo sounder reported on the same grid resolution of the bathymetric maps of the X-band radar images.

AB Change in the drain and gate current low frequency noise (LFN) spectra of GaN-on-Si high electron mobility transistors (HEMTs) is measured before and after the application of electric field stressing on the gate. Extracted Hooge parameters are found to be consistent with previous research. RTS noise spectra are found to appear superimposed upon the 1/f spectrum after device stress. Time constants of the RTS spectra are characterized over a range of temperatures and voltages. It is found that RTS noise time constants change with ln(tau(rts)) proportional to 1/kT allowing trap activation energies to be calculated. Electron trapping mechanisms responsible for the modification of the RTS spectra are discussed in connection with degradation processes induced by field dependent stressing.

These update message can take different times to traverse the network, which we model as exponential service times, and may result in packets reaching the destination out of order, rendering some of the earlier transmissions obsolete. We analyze the status update age for such a system, and show that it tracks well with simulation results.

AB Future US Navy ships are expected to use multifunction, low radar cross section (RCS) phased array antennas for satellite communications. In this paper, we present a unique phased array concept in which a single planar array antenna (on a mobile earth station) can be used to communicate simultaneously with several geostationary (GEO) satellites by generating multiple independent beams. This array will have full electronic beam scanning capability in the azimuth direction with fixed beam positions in the orthogonal (elevation) plane using one or at most two hard-wired squints without the need for redesigning the antenna for different earth station locations. The proposed technique will reduce the cost and complexity of phased array antennas designed for mobile earth stations.

AB Day recently obtained phase-only element weights for a large transmit array of arbitrary geometry by optimizing complex weights using an objective function that penalized amplitude variation. He used gradient descent modified with a classic SVD technique to create point and sector nulls as desired.
Here Day's approach is extended to allow for main-beam broadening as might be needed to illuminate multiple receive beams. This is done by adding a second objective term, one penalizing variation in array-factor amplitude across a grid of beamspace points covering the desired broad main beam. The tension between the two objective terms turns out to be challenging to manage, and at this preliminary stage of algorithm development, parameter scheduling across a sequence of stages of the optimization is required to obtain good solutions.

AB There has been a significant increase in developing multifunction wideband arrays to consolidate the large number of narrowband reflector antennas on US Navy ships. However, the use of conventional methods results in a need for an extremely large number of radiating elements to populate these arrays resulting in a complex and costly multifunction array. We propose architectures that use wavelengthscaled arrays in combination with asymmetrical distribution of arrays to reduce the number of radiating elements by more than a factor of two as well as ease bandwidth requirements. Additionally, a combination of rectangular and square apertures is used, where possible to help further reduce the number of simultaneous beams from any section of the full array. These proposed architectures are capable of providing eight different beams from a single wideband multifunction array.

ID SYSTEM
AB LWA1 is a new large radio telescope array operating in the frequency range 10-88 MHz, located in central New Mexico. The telescope consists of about 260 pairs of dipole-type antennas whose outputs are individually digitized and formed into beams. Simultaneously, signals from all dipoles can be recorded using one of the telescope's "all dipoles" modes, facilitating all-sky imaging. Notable features of the instrument include four independently-steerable beams utilizing digital true time delay beamforming, high intrinsic sensitivity (approximate to 6 kJy zenith system equivalent flux density), large instantaneous bandwidth (up to 78 MHz), and large field of view (about 3-10., depending on frequency and zenith angle of pointing). This paper summarizes the design of LWA1, its performance as determined in commissioning experiments, and results from early science observations demonstrating the capabilities of the instrument.

AB We characterize photodiode-induced second-order intermodulation distortion (IMD2) implementing a new Mach-Zehnder modulator (MZM) distortion cancellation technique. The magnitude and relative phase of photodiode IMD2 can be determined by measurement of an intensity-modulated directdetection (IMDD) link at the cancellation condition. The magnitude is also found through photodiode fundamental frequency response and calculated second-order output intercept point (OIP2). Experimental results show that the IMDD technique is suitable for rapid amplitude estimation, while also providing phase information for the photodiode non-linearity.

AB One-dimensional (1D) and two-dimensional (2D) drift-diffusion models were created to investigate the sources of nonlinearity in a high-current p-i-n photodetector. Incomplete ionization, an external circuit, and impact ionization are all included in the model. We achieve good agreement with the experimental data with both the 1D and 2D model. We show that impact ionization is the dominant source of device nonlinearity at large applied reverse bias. The electron and hole current contributions to the second harmonic power were calculated. We find that the impact ionization is more important for the electrons. We also find that the hole velocity saturates slowly with increasing reverse bias, and the hole current makes a large contribution to the harmonic power at 10 V. This result implies that decreasing the hole injection will decrease the harmonic power.

AB In communication networks, it is often useful to partition the networks into disjoint clusters so that hierarchical protocols, such as hierarchical routing, can be used. Many clustering techniques have been developed for this purpose, including connectivity-based, centroid-based, and spectral methods. One issue with all of these methods is how to select an appropriate number of clusters from the structure of the network. In this paper, we consider clustering techniques based on spectral graph theory in which the relations among nodes in a communication network are mapped onto a graph. We consider techniques that are designed to minimize the multiway normalized cut, a metric that tries to simultaneously minimize the number of edges cut between clusters while balancing the volumes of the clusters. We develop a new method for determining the number of clusters based on the eigenvalues of a normalized graph Laplacian matrix by comparing the eigenvalues to the statistics of a certain type of random cut of the graph. Performance results are presented to demonstrate the effectiveness of our algorithm.

AB We consider two games played between a spectrum manager and an adversary. The manager attempts to allocate spectrum to primary DoD wireless users and secondary non-DoD users by means of a dynamically updated database. The adversary attempts to detect the presence of DoD users within a cell by querying the database. To prevent this, the manager may add false allocation entries into the database at the cost of possibly excluding legitimate secondary users. We calculate the Nash equilibria of these games and show that they can be surprisingly favorable to the DoD and the secondary network. The manager can ensure that the enemy derives no utility from the database without excluding many secondary users on average.

AB The minimum-length scheduling problem has recently been studied for wireless networks with a realistic physical interference model. In these approaches, the propagation delay is ignored due to the relatively fast speed of RF waves compared to the transmission duration. However, signals in underwater acoustic networks travel at a much slower speed, so the propagation cannot be ignored in determining the transmission schedule. In this work, we highlight the difficulty in determining the minimum-length schedule for networks with non-negligible propagation delays, and we identify some special cases in which the approach without propagation delays can be applied, in some cases yielding an optimal schedule.

AB One intermediate goal towards achieving universal secure voice interoperability in the Department of Defense (DoD) has been the development of a universal voice encoder (vocoder). This vocoder would seamlessly encode speech at a wide range of interoperable variable and fixed data rates to suit a wide range of DoD communication equipment. This paper describes the most important features of such a vocoder and recent advancements in achieving this goal. Specifically this paper will describe three main areas: 1) Summary of the variable data rate (VDR) algorithm and the most recent improvements to the vocoder. 2) Methods for transcoding between fixed rate and variable data rate vocoding modes. 3) Summary of heavily bit error protected, fixed-rate modes.

AB The hardware identifiers of common wireless protocols can be exploited by adversaries for both tracking and physical device association. Rather than examining hardware identifiers in isolation, we observe that many modern devices are equipped with multiple wireless interfaces of different physical types, e. g. GSM and 802.11, suggesting that there exists utility in cross-protocol hardware identifier correlation. This research empirically examines the feasibility of such cross-protocol association, concentrating on correlating a GSM hardware identifier to that of the 802.11 hardware identifier on the same device. Our dataset includes 18 distinct mobile devices, with identifiers collected over time at disparate locations. We develop correlation techniques from the perspective of two adversaries: i) limited, able to observe identifiers only in time and space; and ii) a more advanced adversary with visibility into the data stream of each protocol. We first test correlation via temporal and spatial analysis using only basic signal collection, mimicking an RF collection with no decryption or data processing capability. Using a constrained optimization algorithm over temporal and spatial data to perform matching, we demonstrate increasing association accuracy over time, up to approximate to 80% in our experiments. Our second approach simulates the added capability to collect, decrypt, and reconstruct specific application protocol data, and parses the data of one protocol using search terms derived from the other. With the combined techniques, we achieve 100% accuracy and precision.

DE MapReduce; Hadoop; cross-domain services; multilevel security
AB The Apache (TM) Hadoop (R) framework provides parallel processing and distributed data storage capabilities that data analytics applications can utilize to process massive sets of raw data. These Big Data applications typically run as a set of MapReduce jobs to take advantage of Hadoop's ease of service deployment and large-scale parallelism. Yet, Hadoop has not been adapted for multilevel secure (MLS) environments where data of different security classifications co-exist.
To solve this problem, we have used the Security Enhanced Linux (SELinux) Linux kernel extension in a prototype cross-domain Hadoop on which multiple instances of Hadoop applications run at different sensitivity levels. Their accesses to Hadoop resources are constrained by the underlying MLS policy enforcement mechanism. A benefit of our prototype is its extension of the Hadoop Distributed File System to provide a cross-domain read-down capability for Hadoop applications without requiring complex Hadoop server components to be trustworthy.

AB Civilian and military networks are continually probed for vulnerabilities. Cyber criminals, and autonomous botnets under their control, regularly scan networks in search of vulnerable systems to co-opt. Military and more sophisticated adversaries may also scan and map networks as part of reconnaissance and intelligence gathering. This paper focuses on adversaries attempting to map a network's infrastructure, i.e., the critical routers and links supporting a network. We develop a novel methodology, rooted in principles of military deception, for deceiving a malicious traceroute probe and influencing the structure of the network as inferred by a mapping adversary. Our Linux-based implementation runs as a kernel module at a border router to present a deceptive external topology. We construct a proof-of-concept test network to show that a remote adversary using traceroute to map a defended network can be presented with a false topology of the defender's choice.

AB A new procedure for the extraction of noise parameters of on-wafer devices is presented and validated experimentally for the first time. The procedure is based on the noise figure measurement of similar devices of different size and biased at constant drain current density J(ds) and constant drain voltage V-ds. Key to its implementation is a scalable noise model. The model in use is the Pospieszalski noise model, based on the equivalent noise temperatures T-gs and T-ds, of the gate-source and the drain-source resistance, respectively. The new procedure also outlines a path towards the experimental validation of all the noise temperatures associated with the device's lossy elements.

AB Passive detection of shielded special nuclear material (SNM) is a difficult problem, particularly at standoff distances. The SuperMISTI coded imaging and detection system was used with pulsed bremsstrahlung at the Hermes-III facility at Sandia National Laboratories to study active interrogation techniques as an alternative method of detecting shielded SNM. A combination of high-and low-Z shielding of varying thicknesses was used. Delayed gamma and neutron signatures were measured using NaI and He-3 detectors, and signal-to-background ratios were calculated. Experimental setup details and results will be presented.

AB We report on a collaborative test campaign conducted at the Naval Research Laboratory's Mercury pulsed power facility in December of 2012. The experiment sought to use Mercury in the Intense Pulsed Active Detection (IPAD) [1] mode to interrogate a fissionable material target (depleted uranium, DU) and benchmark the effects of shielding the target with either a low-Z (2% borated high-density polyethylene, BPE) or high-Z (steel) material. A large suite of instrumentation, including He-3, BF3, NaI(Tl), and liquid scintillation detectors were used to measure the delayed. and neutron signatures from the DU. The test campaign consisted of a series of single IPAD pulses, i.e., "shots," employing incremental shielding configurations of BPE (up to 50 g/cm(2)) and steel (up to 150 g/cm(2)) encapsulating the DU target. We show the results from each detector array, for varying amounts of shielding, in terms of the signal-to-noise vs. time.

AB We demonstrate an integrated waveguide technology and apply it to displacement sensing. The waveguide consists of a 175 nm thick Si3N4 core layer with a 3,000 nm SiO2 bottom cladding and exhibits a large evanescent field. Although the nanophotonic waveguides feature sub-lambda/4 vertical confinement, they are fabrication tolerant with micron-scale lateral features. The technology enables complex photonic circuits without electron-beam lithography, which is commonly required for silicon nanophotonics. An unbalanced Mach-Zehnder interferometer is demonstrated in which the presence of an optical fiber near the waveguide surface induces a phase shift, which correlates with the fiber's position. We discuss future work and prospects for high-resolution displacement sensing.

ID SYSTEM
AB A chemiresistor vapor sensor based on electron transport through an ensemble of ligand-stabilized gold nanoclusters is made exceptionally sensitive and selective by terminal carboxylic acid functionalization of the alkanethiol ligand. The directionality of the response (conductance increase or decrease) is strongly dependent on the nanoscale dimensions of the gold core and ligand shell thickness. Films of gold nanoclusters composed of a 2 nm metal core with a 0.5 nm -S(CH2)(5)COOH shell are compared to those based on an 8 nm core and a 1.5 nm -S(CH2)(15)COOH shell. Very strong and selective responses to amine vapors are observed but with a reversal of response in the direction of the conductance transduction. This unexpected result cannot be accommodated by known vapor response transduction mechanisms. A speculative new mechanism based on an ionic capacitance generated by the ligand-vapor interaction and confined to the outer surface fraction of the ligand shell is proposed.

AB We demonstrate a path towards the miniaturization of fiber-optic acoustic sensors based on simple cantilever designs. The reduction in response due to miniaturization is offset by the introduction of a viscous fluid around the cantilever, which changes the dominant driving force and introduces damping. This dramatically changes the response and enables responses 10 times greater than otherwise expected, as well as increased operating bandwidth. We show the performance of several different cantilever sensors and the effect of different viscous fluids on their acoustic response. Theoretical modeling results show excellent agreement with our measured data.

AB We present an architecture for combining two established network paradigms, IP and Disruption-Tolerant Networking (DTN), into a unified packet gateway design that leverages the advantages of both. Vehicular networking (VNET) scenarios often involve brittle links between communicating nodes due to their mobility. DTN solutions, by using a dynamic hop-by-hop delivery model instead of the end-to-end IP model, are able to sustain a large class of applications despite intermittent links. As a defining characteristic, our design is application-transparent in that it requires no changes to host applications (or the underlying host protocol stacks) in order for them to use DTN transport when IP is not feasible. In addition, we build into the architecture an explicit disruption notification service for keeping users informed as well preventing application time-outs during an IP outage. Finally, given the wide range of behaviors exhibited by applications that can benefit from DTN, our design supports the notion of an application lattice to allow operators to customize, on a per application/group/protocol basis, how the switch between IP and DTN and the disruption notification are performed. A preliminary evaluation based on a C++ proof-of-concept implementation has illustrated several potential benefits of the proposed architecture for VNET applications.

AB Screening methods are beneficial for studies involving simulations that have a large number of variables where a relatively small (but unknown) subset is important. In this paper, we show how a newly proposed Lasso-optimal screening design and analysis method can be useful for efficiently conducting simulation screening experiments. Our approach uses new criteria for generating supersaturated designs, and a new algorithm for selecting the optimal tuning parameters for Lasso model selection. We generate a 24x69 Lasso optimal supersaturated design, illustrate its potential with a numerical evaluation, and apply it to an agent-based simulation of maritime escort operations in the Strait of Gibraltar. This application is part of a larger project that seeks to leverage simulation models during the ship design process, and so construct ships that are both cost effective and operationally effective. The supersaturated screening design has already proved beneficial for model verification and validation.

ID QUANTILE
AB The density of stochastic simulation output provides more information on system performance than the mean alone. However, density estimation methods may require large sample sizes to achieve a certain accuracy or desired structural properties. A nonparametric estimation method based on exponential epi-splines has shown promise to overcome this difficulty by incorporating qualitative and quantitative information that reduces the space of possible density estimates substantially. Such 'soft' information may come in the form of the knowledge of a non-negative support, unimodality, and monotonicity, and is often available in simulation applications. We examine this method for output analysis of stochastic systems with fixed input parameters, and for a model with stochastic input parameters, with an emphasis on the use of derivative information.

AB We all know how to estimate a confidence interval for the mean based on a random sample. The interval is centered on the sample mean, with the half-width proportional to the sample standard error. We know also that terminating simulations generate independent observations. What simulators appear to have overlooked is that independence alone is insufficient to guarantee a valid random sample-the observations must also be identically distributed. This is a good assumption if the outcome of each replication is a single observation, but it is demonstrably incorrect if the outcome is an aggregate value and the replications have differing numbers of observations. In this paper we explore the implications of this oversight when within-replication observations are independent. We then derive analytic results showing that although the impact on interval estimates can sometimes be negligible, there also are circumstances where the variance of our estimates is significantly increased. We finish with a simple example which demonstrates the potential impact for practitioners.

AB The procurement planning for high value assets, such as submarines, naval surface ships, aircraft, etc. requires rigorous analysis to ensure that the operation of the platform and its sub-systems meet the capability requirements, based on measures of performance. Measures of performance are identified and defined in a capability analysis, which is not in the scope of the present study. Once the measures of performance have been established, a submarine simulation model can be used to assess the performance of a given design against the measures of performance.
Subject matter experts are able to develop high fidelity models of submarine performance and operations. An efficient way to integrate these high fidelity models, to develop a whole-of-submarine simulation model, is to use an integration tool such as Phoenix Integration Model Center. This integrated tool can be used to perform analysis and parameter sensitivity studies to provide a better understanding of the design space.
In this paper, a submarine simulation model is developed, using Phoenix Integration Model Center, based on sub-system models developed by subject matter experts. The software tool is validated by comparing the designs to several previous designs described in the public literature.
The tool is then applied to a case study, showing the relationship between the weight of a submarine, the number of crew members and the length of its mission in days. The results show a large growth in submarine weight with increasing crew numbers, and a moderate growth in weight with increased mission duration.

AB Purpose - This chapter studies the transfer of performance measurement system (PMS) innovations across the three sectors of the economy: private, public, and nonprofit.
Methodology/approach - The spread of organizational innovations and learning from best practices is slow and complicated (Lillrank, 1995). Based on differences in languages used by writers and readers and differences in employee characteristics among the three sectors as well as cognitive biases, we expect the transfer of PMS innovations to be easier within sectors than across sectors. We use the frequency and timing of journal articles written about activity-based costing and the balanced scorecard as a proxy for the actual transfer of the innovations within and across economic sectors.
Findings - Our empirical results indicate that the transfer of the ideas across economic sectors does not happen as quickly as the transfer of the ideas within sectors. We provide evidence that it is the practitioners, not the academics, who lead the transfer of ideas in the open literature from one sector to another. Viewing a sector as unique limits the applicability of available solutions and applications, thereby inhibits useful change.
Originality/value of paper - By focusing on differences, the exchange of ideas and techniques among the three economic sectors can be hindered.

AB Elastic and inelastic neutron scattering angular distributions have been measured from Na-23 for incident neutron energies between 2 and 4 MeV at the University of Kentucky using neutron time-of-flight techniques. The cross sections obtained are important for applications in nuclear reactor development and other areas, and they are an energy region in which existing data are very sparse. Absolute cross sections were obtained by normalizing Na angular distributions to the well-known np cross sections.

AB The N=88 nucleus Sm-150 has been produced during the Nd-148(alpha,2n)Sm-150 reaction at the Accelerator Laboratory of the University of Jyvaskyla, Finland. Nuclei around the N=90 are considered transitional nuclei, since they lie in a region between lighter nuclei which display vibrational-like spectra and heavier isotopes with a rotational-like structure. The structure of this transitional nuclei and in particular the structure of low-lying excited states still poses some question, and in particular more experimental data are required to investigate their non-yrast collective structures. Some preliminary results which include the placing of new levels and a new positive parity band will be presented.

AB We give a new probabilistic algorithm for interpolating a "sparse" polynomial f given by a straight-line program. Our algorithm constructs an approximation f* of f, such that f-f* probably has at most half the number of terms of f, then recurses on the difference f-f*. Our approach builds on previous work by Garg and Schost (2009), and Giesbrecht and Roche (2011), and is asymptotically more efficient in terms of the total cost of the probes required than previous methods, in many cases.

AB Purpose - This chapter examines the debt aversion of a group of college students who have the opportunity to take out a sizable, low-interest, non-credit dependent loan. If the loan is simply invested in low-risk assets, it would effectively yield a free lunch in net interest earnings.
Methodology - The research uses survey data to examine demographic, socio-economic, personality traits, and other characteristics of those willing and unwilling to accept the loan offer, as well as their intentions of early repayment.
Findings - Individuals willing to accept the loan tend to have prior debt, longer planning horizons, come from middle-income families, and may have higher cognitive ability. Anticipated early repayment of the loan is more likely among those with prior investments, no prior debt, from STEM majors, with upper income parents, and those who expect to buy a home soon.
Research limitations/implications - We find no consistent relationships between debt aversion and intellectual ability or gender, but this finding may be hampered by our small sample of female loan-rejecters. Our limited sample size also precludes examining interactions between the dimensions of personality types.
Originality - We suggest consideration of policies to encourage "smart" borrowing, focusing on the financially disadvantaged, particularly for education loans. This study examines a uniquely occurring natural experiment regarding the opportunity to accept a non-credit dependent loan. Our results describe the behavior of young adults, an infrequently studied yet important segment of the population, especially in the context of borrowing behavior.

AB Approaches to harness recent advances in capabilities of a fast steering mirror (FSM) in its size, range of motion, and control bandwidth are explored to enhance the slew, settle, and jitter suppression performance of optical telescope assembly (OTA) payloads as well as their host satellites. As a point study to assess the slew and settle performance benefits of using FSMs and to study their integration approaches for a satellite hosting an OTA payload, the step-stare observation of the Joint Milli-Arcsecond Pathfinder Survey (JMAPS) mission was considered in this paper. The first approach studied was to install an FSM in front of the OTA to perform the step-stare operation by steering the FSM without maneuvering the host satellite. The second approach was to use the satellite bus and its attitude control system to perform slews while employing the FSM to improve settling performance after the slew. The first approach was effective in reducing slew and settle duration, which may take up a significant portion in time in the step-stare observation sequence. However, it required a sizeable FSM mirror with a large range of motion capability in order to accommodate the OTA aperture size. The second approach was beneficial in reducing the required size and range of motion of the FSM by allowing the integration of the FSM within the OTA but was not as effective in reducing the slew and settle time as the first approach since the slew was conducted by the satellite bus. Although preliminary in nature, this study supports that FSMs can be an effective alternative to improving agility and pointing stability for future satellites hosting OTA payloads.

AB At the request of the Domestic Nuclear Detection Office (DNDO), a Study Committee comprised of representatives from the American Physical Society, Panel on Public Affairs, the IEEE, and Nuclear and Plasma Sciences Society performed a technical review of the DNDO Transformational and Applied Research Directorate (TARD) R&D program. TARD's principal objective is to address gaps in the Global Nuclear Detection Architecture (GNDA) through improvements in the performance, cost, and operational burden of detectors and systems. The charge to the Study Committee was to investigate the existing TARD R&D plan and portfolio, recommend changes to the existing plan, and recommend possible new R&D areas and opportunities. This report is the result of an independent, detailed analysis of the current R&D plan and includes, for each application area, observations, and recommendations to focus future investments within the context of the TARD mission.

AB A stereoscopic particle image velocimetry (SPIV) system was used in a low-speed wind tunnel to measure the external flowfield of a circulation control (CC) wing having an aspect ratio of 1.1. This ongoing project, sponsored by the Office of Naval Research, sought to further the knowledge of the jet interactions and the wingtip vortex formation through 3-component, planar velocity surveys. The CC wing tested had a 20% elliptic airfoil section with a trailing edge Coanda surface that was intended to increase circulation control effectiveness throUgh a segmented system that could create spanwise massflow efflux profiles.
To date, 1.2 TB of raw SPIV data have been acquired in one of two wake station planes at z/c = 1.25 over the vertical region of 0.13. < y/b < 0.87 (i.e, the tip region). The three-component velocity data revealed the nature of the interaction of the jet with the external flowfield and the temporal variability at an overall momentum coefficient of 0.08 with spanwise variations in the trailing edge efflux. The results from these tests will be used to quantify, for the first time, the effects of spanwise massflow distributions on the 3D velocity field near the trailing edge, the stall modes, jet interactions, and the overall performance of a CC wing of this geometry

AB The fabrication of complex ceramic components requires new processing methods that are able to produce components with intricate geometries and accurate dimensions. The accuracy of the finished ceramic component depends upon precise control of the green ceramic body dimensions and uniformity prior to sintering. The authors are investigating the application of the fugitive phase approach, where a sacrificial material is used to form cavities or channels in the finished ceramic component. This paper, a continuation of a previous work, examines the lamination step of the fugitive phase approach for ceramic fabrication. The lamination step is where the fugitive phase pieces are combined with the tape cast green ceramic pieces. The multilayer green body is pressed to laminate the ceramic tape and fugitive phase layers together. Topological complexity is greatly increased when the tape cast ceramic pieces are interspersed with fugitive phase pieces to build up a consolidated multilayer green body. This paper examines the movement of the fugitive phase pieces, viscoelastic deformation of the ceramic phase, the filling of voids, pressure gradients, and the rebounding that occurs when the green ceramic body is removed from the press. This information will be used to complement parallel experimental investigations of the fugitive phase approach to ceramic fabrication.

TI INTEGRATION OF CARBON FIBER COMPOSITE MATERIALS INTO AIR-COOLED

AB The United States Navy (USN) has shown an interest in the development of small displacement, reciprocating piston diesel engines for Unmanned Aerial Vehicles (UAVs). These engines avoid the logistic challenges of relying on gasoline-fueled UAVs, and have relatively low fuel consumption, but suffer from poor power-to-weight ratios. Reducing weight is of significant importance to UAVs to allow sufficient range and loitering times. Carbon fiber composites offer strength-to-weight benefits over the metal components currently used in piston engines. However, composite components have more restrictive operating temperatures. None of the known previous efforts aimed at integration of composites into engines has focused on air-cooled engines and on their potential benefits for UAVs. A small, single-cylinder air-cooled gasoline engine was chosen as a convenient test platform and surrogate for an air-cooled UAV engine. The crankcase and connecting rod from this engine were redesigned using a high fraction of carbon fiber in order to reduce weight. To develop the designs, steady-state temperature profiles were measured both internally and externally. The steady state temperatures for the crankcase ranged between 93 degrees C and 124 degrees C while the connecting rod ranged roughly between 120 degrees C and 160 degrees C. Carbon fiber composite test specimens were tested for strength at a comparable range of temperatures to demonstrate thermal viability. The tensile and compressive tests showed the carbon fiber to be comparable to all aluminum material properties, if not better. Stress was modeled on the stock engine at the worst-case operating condition and used to design the composite crankcase and connecting rod to ensure sufficient strength to survive at this extreme condition. The modeled stresses resulted in a factor of safety of 1.5 for the connecting rod and 3.8 for the crankcase, although internal adhesion of bearing surfaces to fiber was noted as a problem for the connecting rod in the initial prototype, and ultimately led to premature failure. These composite components were integrated and tested, for various lengths of time, on the engine and indicate a potential weight savings of approximately 80% for the crankcase and 26% for the connecting rod. The composite case failed after approximately 20 minutes (O(10(4)) cycles) of operation at the best torque condition (worst-case in terms of mechanical stress) due to manufacturing deficiency at the corners and base; the connecting rod failed after approximately 2 minutes (O(10(3)) cycles) of worst-case operation due to separation of the bearing surface from fiber. Both sets of failures point to simple remedies for follow-on work. The initial prototypes resulted in an overall weight savings of 8.1%. Using commercially available data for small propeller-driven aircraft, this weight savings could be expected to result in a similar relative improvement in aircraft range.

AB Thermal design was incorporated into an undergraduate heat transfer course through a multistage design project. The students were tasked with designing water channels to be cut in an aluminum block using a wire electrical discharge machining (EDM) process. The students begin the process by analyzing the internal channels as a one dimensional array of fins using traditional analysis and correlations and Engineering Equation Solver (EES) to perform the calculations. Working in groups of two, the students conduct several parametric studies and develop a preliminary design using an array of fins method. The requirements for the design included outcomes that had to be met, along with weighting factors for key aspects of the design such as thermal performance, pressure drop, fabrication cost and volumetric flow rate. Next, the students analyze their preliminary design using Solid Works flow simulation and compare their results to the one dimensional array of fins analysis. The groups then begin the process of refining their design using Solid Works flow simulation to predict key parameters. Finally, the students select their best design which is fabricated using a wire EDM machine. The heat sinks are tested using a single experimental apparatus and the best design is determined based on the original requirements. The project is first introduced when the students are covering resistor networks and the analysis of an array of fins. The computational aspect of the project begins after the students have covered steady state conduction using finite difference methods. Using the computational results the students plot the heat transfer coefficient on the surface of the channel, which complements the lectures on internal developing flows.

AB Characteristics of the annealed state of yttria and scandia stabilized zirconia have been investigated using molecular dynamics simulations. A genetic algorithm was used to find the minimal energy configuration of dopant ions to simulate the effects of annealing for compositions of 8 mol% Y2O3 in ZrO2, and compositions with 9, 10 and 11 mol% Sc2O3 with, respectively, 2, 1 and 0 mol% Y2O3 in ZrO2. Conductivity and diffusion coefficients were calculated in each case, and it was discovered that the conductivity increased when the dopant ions were located distant to each other, and the number of first neighbor dopant-dopant pairs were reduced. Furthermore, the Haven ratio was calculated to be on the order of 0.9 for the 11 mol% doped specimens, but substantially lower for the 8 mol% yttria in zirconia specimens.

AB The US Navy is at a critical juncture in determining the types and numbers of ships it will acquire, retire, and sustain to support an evolving US military strategy. In addition to determining how many aircraft carriers, cruisers, amphibious assault craft, fighters, and helicopters it will need, the Navy must determine how it will confront maritime irregular warfare. Assuming an environment of resource scarcity, where new vessel acquisition to support maritime irregular warfare may be increasingly difficult or unlikely, we introduce a method for evaluating the capability and costs of candidate vessels that are in the current Department of Defense inventory, or widely available from the commercial sector to conduct such a mission. Our method combines wargaming with cost analysis to aid Navy leadership in developing maritime irregular warfare concepts of operation as well as resource allocation decisions.

TI Optimizing Intratheater Military Airlift in Iraq and Afghanistan
SO MILITARY OPERATIONS RESEARCH
LA English
DT Article
AB The Air Tasking and Efficiency Model (ATEM) has been used since 2006. Its development was motivated by an urgent need to plan and evaluate intratheater airlift of passengers and palletized freight for Operation Iraqi Freedom in Iraq and Operation Enduring Freedom in Afghanistan. ATEM plans routes and aircraft configurations (capacity of passenger seats and pallet positions) for a heterogeneous fleet of aircraft flying between multiple airfields. ATEM respects limits on crew duty periods, times and abilities of each airfield to handle and fuel each aircraft type, and aircraft speed and carrying capacity. Initially, ATEM advised improving daily and weekly route ensembles, conveying more passengers and pallets and using fewer aircraft than prior manually generated solutions. This early use reduced the required number of ground convoys and thereby exposure to improvised explosive devices. Later, AI EM advised where to advantageously move aircraft to new home airfields, how to shift aircraft between theaters, and when to bring aircraft home from war.

AB A common concern raised in opposition to Appreciative Inquiry (AI) is that a focus on life-giving images in organizations tends to suppress negative voices. It is supposed that AI sees little value in skeptical, cynical, or negative perspectives. However, when AI is properly understood, all voices - both positive and negative - are seen as essential to the life of organization. The challenge is to create an atmosphere in which the cynical voice, rather than perpetuating dysfunction, can be tapped to build generativity. This chapter describes how to accomplish this objective through the use of analogic inquiry, thus exploring the focus on generativity that is central to AI.

AB A spectral domain method is presented to calculate the potential of a vertical dipole in a multilayered medium as a model of long-range radio propagation. The spectral domain Green's function (SDGF) for structures with up to hundreds of thousands of layers is calculated using an efficient matrix formulation, thus enabling simulation of continuously stratified media. The SDGF is sampled to perform pole/residue-extraction using contour quadratures and to perform a novel asymptotic Filon-Clenshaw-Curtis (FCC) quadrature to calculate the far-field Green's functions. The near-fields are directly calculated using an adaptive Clenshaw-Curtis quadrature without pole-extraction. Results of numerical simulations are presented in the case of a graded-index waveguide and an atmospheric gradient-layer above a realistic lossy ground.

AB Rotating disk electrode voltammetry has been touted as a simple means for benchmarking the oxygen reduction activity of platinum-based catalysts in proton exchange membrane fuel cells. The RDE methodology is still highly variable across laboratories, and due to differences in experimental conditions, up to 2.5x differences in mass activities are reported in recent literature from the same catalyst. We demonstrate an RDE protocol, and show that it can be replicated in two different laboratories. Uniform RDE methodology should be developed so that advanced catalysts can be compared between laboratories.

AB The NRL rotational drying method was used to prepare thin film Pt/C electrodes. The electrodes were characterized by the RRDE mearsurements, in which the disk curves were used for the ORR kinetic measurements and the ring curves for the H2O2 production evaluation. The reproducibility of both ring and disk currents for the ORR was investigated. It is demonstrated that RRDE methodology was highly repeatable with the use of the high quality films obtained from the rotational drying method. The results were also repeatable across laboratories, even when different measurement equipment was used, as long as attention was paid to key details about film preparation, chemical and gas purity, and cycling procedures. The rotational drying method for the RRDE measurements make it possible in getting highly reliable and reproducible performance data on the catalysts, which is crucial for the validation of the advancement in catalysts at various laboratories.

AB The light curves of gamma-ray pulsars detected by the Fermi Large Area Telescope show great variety in profile shape and position relative to their radio profiles. Such diversity hints at distinct underlying magnetospheric and/or emission geometries for the individual pulsars. We implemented an offset-dipole magnetic field in an existing geometric pulsar modelling code which already includes static and retarded vacuum dipole fields. In our model, this offset is characterised by a parameter epsilon (with epsilon = 0 corresponding to the static dipole case). We constructed sky maps and light curves for several pulsar parameters and magnetic fields, studying the effect of an offset dipole on the resulting light curves. A standard two-pole caustic emission geometry was used. As an application, we compared our model light curves with Fermi data for the bright Vela pulsar.

AB Guillemot et al. recently reported the discovery of gamma-ray pulsations from the 22.7 ms pulsar (pulsar A) in the famous double pulsar system J0737-3039A/B. The gamma-ray light curve of pulsar A exhibits two peaks separated by approximately half a rotation, and these are noncoincident with the observed radio and X-ray peaks. This suggests that the gamma-ray emission originates in a part of the magnetosphere distinct from where the radio and X-ray radiation is generated. Thus far, three different methods have been applied to constrain the viewing geometry of pulsar A (the inclination angle between its magnetic and rotation axes, and the observer angle): geometric modelling of the radio and gamma-ray light curves, modelling of the position angle sweep in phase seen in the radio polarisation data, and independent studies of the time evolution of the radio pulse profile of pulsar A. These three independent, complementary methods have yielded consistent results: pulsar A's rotation axis is likely perpendicular to the orbital plane of the binary system, and its magnetic axis close to lying in the orbital plane (making this pulsar an orthogonal rotator). The observer is furthermore observing emission close to the magnetic axis. Thus far, however, current models could not reproduce all the characteristics of the radio and gamma-ray light curves, specifically the large radio-to-gamma phase lag. In this paper we discuss some preliminary modelling attempts to address this problem, and offer ideas on how the light curve fits may be improved by adapting the standard geometric models in order to reproduce the profile peak positions more accurately.

AB We modelled the radio and gamma-ray light curves of millisecond pulsars using outer gap, two-pole caustic, low-altitude slot gap, and pair-starved polar cap geometric models, combined with a semi-empirical conal radio model. We find that no model fits all cases, with the outer gap and two-pole caustic models providing best fits for comparable numbers of millisecond pulsar light curves. We find a broad distribution of best-fit inclination angles as well as a clustering at large observer angles. The outer gap model furthermore seems to require relatively larger inclination angles, while the two-pole caustic model hints at an inverse trend between inclination angle and pulsar spin-down luminosity.

AB The network design process today remains ad-hoc and largely complexity agnostic, often resulting in suboptimal networks characterized by excessive amounts of dependencies and commands in device configurations. The unnecessarily high configuration complexity can lead to a huge increase in both the amount of manual intervention required for managing the network and the likelihood of configuration errors, and thus must be avoided. In this paper we present an integrated top-down design approach and show how it can minimize the unnecessary configuration complexity in realizing user reachability control, a key network design objective that involves designing three distinct network elements: VLAN, IP address, and packet filter. Capitalizing on newly-developed abstractions, our approach integrates the design of the three elements into a unified framework by systematically modeling how the design of one element may impact the complexity of other elements. Our approach goes substantially beyond the current "divide-and-conquer" approach that designs each element in complete isolation, and enables minimizing the combined complexity of all elements. Specifically, two new optimization problems are formulated, and novel algorithms and heuristics are developed to solve the formulated problems. Evaluation on a large campus network shows that our approach can effectively reduce the packet filter complexity and VLAN trunking complexity by more than 85% and 70%, respectively, when compared to the ad-hoc approach currently used by the operators.

AB As the main constituents of cohesive sediments in natural waters, clay particles always interact with the waterborne extracellular polymeric substances (EPS) exuded by microorganisms, or exopolymers, resulting in fractal clay-EPS flocs and hence change in sediment transport. During the transition of cohesive sediments from fresh water to salt water in the estuarine areas, the clay-to-clay and clay-to-EPS interactions will be influenced by the salinity change and thus the alternation to sediment transport. This study investigated the influence of a neutral exopolymer, guar gum, on the size, settling velocity, and fractality of clay flocs in both fresh and sea waters. To account for the variety of different clay types in natural cohesive sediments, four clays, namely kaolinite, illite, Ca- and Na-montmorillonite, were used as the inorganic constituents of flocs. To simulate the water chemistry in coastal areas, fresh water and salt water with a salinity of 35 ppt were used. Experimental results showed that the neutral EPS increased the floc size by promoting flocculation. In fresh water, the floc size increased from similar to 0.1-60 mu m to as large as similar to 100 mu m. The settling velocity of clay-EPS flocs was smaller than pure clay particles of the same size in both fresh and salt water, which may be caused by the reduced density. Due to flocculation, more clay particles are attached to flocs and hence become settable. The fractal dimension of flocs, which was estimated based on a simple floc size-settling velocity model, ranges from 1.763-1.861 for pure clay flocculi, 1.387-1.473 for the clay-EPS flocs, 1.861-1.954 for clay flocculi in salt water, and 1.436-1.905 for clay-EPS flocs in salt water. Both the floc size and settling velocity in salt water are greater than that in fresh water. The increased ion concentration also promotes the flocculation of clay particles and clay-EPS flocs by reducing the double layer thickness and cation bridging, which lead to an increase in floc density and fractal dimension.

AB Cohesive sediments are abundant in natural waters, especially in estuarine and coastal environments where organic matter (particularly extracellular polymeric substances (EPS)) and high water turbulence can lead to the formation of clay-EPS flocs. This flocculation process affects the sediment transport and the geotechnical/geophysical properties of the bottom bed. In order to investigate how EPS concentration and hydrodynamic forcing affect sediment flocculation behavior (e.g., floc size distribution, floc breakdown), a pure clay mineral, Ca-montmorillonite, which is abundant in marine environment and a neutral EPS, guar gum, were used in laboratory to prepare flocs with varying EPS to clay weight ratio (E/C) and the hydrodynamic forcing in a laser diffraction-based particle size analyzer. Results indicate that the cohesive sediment flocs exhibit a multimodal particle size distribution (PSD) in all three flow conditions (i.e., laminar, transitional, and turbulent flows). Statistical deconvolution of the PSD curves suggest that the mixture suspensions consist of four discrete particle groups, consisting of primary particles, flocculi, microflocs, and macroflocs. Neutral guar in anionic Ca-montmorillonite suspensions causes the formation of macroflocs (> 200 mu m) and significantly increases the median particle size by several orders of magnitude when compared with the pure clay. However, adding more guar into the clay does not provide a proportional increase in the macrofloc fraction. Further analysis showed that when the E/C is similar to 2%, which is proposed as a critical value, macroflocs have the largest fraction of the entire population, while microflocs make up the smallest one. This demonstrates that smaller microflocs are most likely to form macroflocs at an E/C of 2% through flocculation, assisted and influenced by van der Waals forces, H bond, and other mechanisms as well as physical and chemical properties of Ca-montmorillonite and guar (e.g., specific surface area, surface charges, swelling properties, number of surface active sites, interlayer cations, and EPS polarity). Further, considering the effect of hydrodynamic forcing, macroflocs are weak and can easily breakdown into smaller microflocs when the flow conditions change from laminar to transition or turbulence, due to the breakage of weaker bonds inside the macroflocs.

AB The escape of salmon from aquaculture farms is considered a major problem for the industry. Structural failure is the dominating cause for escapes. One major issue is the contact, and subsequent abrasion between the sinker tube chain and the net, which has caused several large-scale escapes over the past years. Model tests were performed in a tow tank at the United States Naval Academy to investigate at which combinations of waves and current the net deforms and comes in contact with the sinker tube chain. A model in scale 1:40 was used to represent a fish cage with a circumference of 120 meters and net depth of 40 meters. Building a physical model of such a compliant structure is inherently difficult, so particular attention was given to similarity issues. With the physical modelling approach, two different net design and four different weighting systems were tested. The experiments showed that the sinker tube with the fixed connection to the net performs better than individual weights both for cylindrical and conical nets. For cylindrical nets exposed to current only contact occurred at a velocity of 0.3 m/s when using weights and at a velocity of 0.5 m/s when using either the fixed or sliding sinker tube. The results for conical nets exposed to waves and current were less consistent. Weights (contact at 0.3 m/s) performed better than a sinker tube with sliding connection (contact due to waves only) but not as good as a fixed sinker tube (contact at 0.3 m/s). When exposed to waves and current contact occurred at a higher velocity and over a smaller area when using the conical net compared to the conventional cylindrical. For cylindrical nets contact occurred when exposed to waves alone, whereas for conical nets contact occurred at current velocities of 0 m/s, 0.15 m/s, and 0.3 m/s for the weights, the sliding sinker tube, and the fixed sinker tube respectively.

AB Practical aero-engine fuel injection systems are highly complicated, combining complex fuel atomizer and air swirling elements to achieve good fuel-air mixing as well as long residence time in order to enhance both combustion efficiency and stability. While detailed understanding of the multiphase flow processes occurring in a realistic injector has been limited due to the complex geometries and the challenges in near-field measurements, high fidelity, first principles simulation offers, for the first time, the potential for a comprehensive physics-based understanding. In this work, such simulations have been performed to investigate the spray atomization and subsequent droplet transport in a swirling air stream generated by a complex multi-nozzle/swirler combination. A Coupled Level Set and Volume Of Fluid (CLSVOF) approach is used to directly capture the liquid-gas interface and an embedded boundary (EB) method is applied to flexibly handle the complex injector geometry. The ghost fluid (GF) method is also used to facilitate simulations at realistic fuel-air density ratio. Adaptive mesh refinement (AMR) and Lagrangian droplet models are used to efficiently resolve the multi-scale processes. To alleviate the global constraint on the time-step imposed by locally activated AMR near liquid jets, a separate AMR simulation focusing on jet atomization was performed for relatively short physical time and the resulting Lagrangian droplets are coupled into another simulation on a uniform grid at larger time-steps. The high cost simulations were performed at the U.S. Department of Defense high performance computing facilities using over 5000 processors. Experiments at the same flow conditions were conducted at UTRC. The simulation details of flow velocity and vorticity due to the interaction of the fuel jet and swirling air are presented. The velocity magnitude is compared with experimental measurement at two downstream planes. The two-phase spray spreading is compared with experimental images and the flow details are further analyzed to enhance understanding of the complex physics.

ID NOISE
AB When the turbulent structures in the shear layer of highspeed jets travel at supersonic convective speeds relative to the ambient speed of sound, they radiate Mach waves that become the dominant component of the overall perceived noise. This is consistent with the OASPL in the far field reaching a maximum in same direction as the Mach wave angle. When the speed of the supersonic jet exceeds a certain level, the steepening of the wave-front in the near field produces a noise feature called "crackle." Both pressure wave steepening and crackle cannot be recognized in the spectrum of the pressure signal, but in the temporal waveform of the pressure. The statistics of the pressure signal and its time derivative, particularly skewness, have become standard measures of crackle in heated supersonic jets. Previous studies showed that it is possible to reduce far-field pressure skewness with the implementation of notched and chevron nozzles, and to mitigate Mach Wave radiation with secondary flow techniques. In this paper, we investigate the effect of chevrons on the pressure and dP/dt high-order statistics of a M-d = 1.5 converging-diverging round conical nozzle, both in the near and far fields. Cold and heated jets, T-o = 300 K and 600 K, are tested at over, design, and under-expanded conditions. Far-field results of the heated jet showed that chevrons effectively reduce elevated levels of skewness and kurtosis of the pressure and dP/dt. These reductions are remarkable especially around the Mach Wave angle, the region in which high-order statistics tend to propagate. Near-field results corroborated the effectiveness of chevrons in the skewness reduction.

AB Recent improvements in the algorithms and associated processes have resulted in significant improvements in the users' ability to obtain aeroacoustics analysis of hot supersonic jets in a timely manner using only moderate computational resources. This paper discusses these approaches using the example of the Compressible High Order Parallel Acoustics (CHOPA) solver. The fundamental strategy looks to balance computational expense with the accuracy required to predict the most important effects. The objective is to resolve the larger eddies accurately, but exchanges the resolution of fine turbulent structures in return for decreased computational resource requirements. These strategies continue to be developed, along with the corresponding software. As the work progresses, the team expects additional improvements in the near future.

ID PERFORMANCE
AB In much of the public literature on pin-fin heat transfer, Nusselt number is presented as a function of Reynolds number using a power-law correlation. Power-law correlations typically have an accuracy of 20% while the experimental uncertainty of such measurements is typically between 5% and 10%. Additionally, the use of power-law correlations may require many sets of empirical constants to fully characterize heat transfer for different geometrical arrangements. In the present work, artificial neural networks were used to predict heat transfer as a function of streamwise spacing, spanwise spacing, pin-fin height, Reynolds number, and row position. When predicting experimental heat transfer data, the neural network was able to predict 73% of array-averaged heat transfer data to within 10% accuracy while published power-law correlations predicted 48% of the data to within 10% accuracy. Similarly, the neural network predicted 81% of row-averaged data to within 10% accuracy while 52% of the data was predicted to within 10% accuracy using power-law correlations. The present work shows that first-order heat transfer predictions may be simplified by using a single neural network model rather than combining or interpolating between power-law correlations. Furthermore, the neural network may be expanded to include additional pin-fin features of interest such as fillets, duct rotation, pin shape, pin inclination angle, and more making neural networks expandable and adaptable models for predicting pin-fin heat transfer.

ID MATRIX COMPOSITES
AB Implementation of ceramic matrix composites (CMCs) in jet engine applications necessitates the understanding of high velocity impact behavior. To this end, various melt-infiltrated SiC/SiC composites were impacted at room temperature at 350 m/s with different support systems and tensile tested to failure. Non-Destructive techniques including electrical resistance (ER) and flash thermography were used to examine the specimen pre and post impact. Some specimens were then post-tested in order to assess retained properties. For post tested specimens acoustic emission was used to monitor damage accumulation during the post test and leading up to ultimate failure. Microscopy was performed to correlate damage with impact and post-impact applied stress. The properties of the impacted specimens were assessed based on relevant damage zones. The results are also compared with similar studies performed on similar composites with stress-concentrators such as holes or notches and post-impact specimens tested in bending.

AB A generalized model for mapping the trend of the performance characteristics of a double-discharge centrifugal fan is developed based on the work by Casey and Robinson (C&R) which formulated compressor performance maps for tip-speed Mach numbers ranging from 0.4 to 2 using test data obtained from turbochargers with vaneless diffusers. The current paper focuses on low-speed applications for Mach number below 0.4. The C&R model uses four non-dimensional parameters at the design condition including the flow coefficient, the work input coefficient, the tip-speed Mach number and the polytropic efficiency, in developing a prediction model that requires limited geometrical knowledge of the centrifugal turbomachine. For the low-speed fan case, the C&R formulas are further modified to apply a low-speed, incompressible analysis.
The effort described in this paper begins by comparing generalized results using efficiency data obtained from a series of fan measurements to that using the C&R model. For the efficiency map, the C&R model is found to heavily depend on the ratio of the flow coefficient at peak efficiency to that at the choke flow condition. Since choke flow is generally not applicable in the low-speed centrifugal fan operational environment, an alternate, but accurate estimation method based on fan free delivery derived from the fan test data is presented. Using this new estimation procedure, the modified C&R model predicts reasonably well using the double-discharge centrifugal fan data for high flow coefficients, but fails to correlate with the data for low flow coefficients. To address this undesirable characteristic, additional modifications to the C&R model are also presented for the fan application at low flow conditions.
A Reynolds number correction is implemented in the work input prediction of the C&R model to account for low-speed test conditions. The new model provides reasonable prediction with the current fan data in both work input and pressure rise coefficients. Along with the developments for the efficiency and work input coefficient maps, the use of fan shut-off and free delivery conditions are also discussed for low-speed applications.

AB Ceramic thermal barrier coatings (TBCs),attributed to their inherent brittle nature, are highly susceptible to damage by impacting foreign particles when the impacting kinetic energy exceeds certain limits. The damage is termed foreign object damage (FOD) in related turbine components and results in various issues/problems to coatings as well as to substrates from delamination to spallation to cracking to catastrophic failure depending on the severity of impact. The FOD testing was performed using a ballistic impact gun for turbine airfoil components coated with 7% yittria stabilized zirconia (7YSZ) by electron beam physical vapor deposit (EB-PVD). A range of impact velocities up to Mach 1 was applied with three different projectile materials of steel, silicon nitride, and glass balls. The damage was assessed and characterized in terms of impact velocity, projectile material, and remaining life of turbine components. An energy-balance approach was made to develop a model to predict delamination of the TBCs upon impact.

AB Ceramic matrix composite (CMC) materials technology is of fundamental importance to gas turbine engine application. POD (foreign Object Damage) in CMC components can result in component localized damage and a loss of post-impact performance. CMC impact generates a varying degree of damage from localized surface damage to complete penetration depending on the severity of impact events. Ceramic Composite equivalent electrical properties are computed based on simplified Multi-scale micromechanics equations. Electrical resistance and/or conductivity are computed utilizing the constituent material properties, effective medium, and percolation theories. Ceramic composite electrical properties simulation requires the algorithm development that combines the effective medium and percolation theories. A physically based percolation model is implemented to characterize the effective electrical conductivity of heterogeneous composites by means of the combination of effective medium (EM) and percolation equations with universal exponents. It is shown that the present model correlates well with the experimental electrical resistivity and acoustic emission data. The change in electrical resistivity after impact is compared with test data of a SA-SiC fiber reinforced SiC matrix composite. The predicted damage after impact and the trend of damage volume correlated well with experimental observations of damage shape and reduction in electrical resistance. Thus, an empirical relationship between damage volume and mechanisms and electrical resistance are developed and presented.

AB This study forms part of a program to develop a microelectro-mechanical-systems (MEMS) scale turbomachinery based vacuum pump and investigates the roughing portion of such a system. Such a machine would have many radial stages with the exhaust stages operating near atmospheric conditions while the inlet stages operate at near vacuum conditions. In low vacuum such as those to the inlet of a roughing pump the flow can still be treated as a continuum however the no-slip boundary condition is not accurate. The Knudsen number becomes a dominant non-dimensional parameter in these machines due to their small size and low pressures. As the Knudsen number increases slip flow becomes present at the walls. The study begins with a basic overview on implementing the slip wall boundary condition in a commercial code by specifying the wall shear stress based on the mean-free-path of the gas molecules. This is validated against an available micro-Poiseuille classical solution at Knudsen numbers between 0.001-0.1 with reasonable agreement found.
The method of specifying the wall-shear stress is then applied to a generic MEMS scale roughing pump stage that consists of two stators and a rotor operating at a nominal absolute pressure of 500 Pa. The zero flow case was simulated in all cases as the pump down time for these machines is small due to the small volume being evacuated. Initial transient two-dimensional simulations are used to evaluate three boundary conditions, classical no-slip, specified-shear and slip-flow. It is found that the stage pressure rise increased as the flow began to slip at the walls. In addition it was found that at lower pressures the pure slip boundary condition resulted in very similar predictions to the specified shear simulations. As the specified-shear simulations are computationally expensive it is reasonable to use slip-flow boundary conditions. This approach was used to perform three-dimensional simulations of the stage. Again the stage pressure increased when slip-flow was present compared with the classical no-slip boundaries. A characteristic of MEMS scale turbomachinery are the large relative tip gaps requiring three-dimensional simulations. A tip gap sensitivity study was performed and it was found that when no-slip boundaries were present the pressure ratio increased significantly with decreasing tip gap. When slip-flow boundaries were present this relationship was far weaker.

ID SURFACE-ROUGHNESS; CASCADE; SEPARATION; FLOW
AB An experimental investigation has been conducted to characterize the influence of leading edge roughness and Reynolds number on compressor cascade profile loss. Tests have been conducted in a low-speed linear compressor cascade at Reynolds numbers between 210,000 and 640,000. Blade loading and loss have been measured with pressure taps and pneumatic probes. In addition, a two-component laser-doppler velocimeter (LDV) has been used to measure the boundary layer velocity profiles and turbulence levels at various chordwise locations near the blade suction surface. The "smooth" blade has a centerline-averaged roughness (R-a) of 0.62 mu m. The "rough" blade is roughened by covering the leading edge of the "smooth" blade, including 2% of the pressure side and 2% of the suction side, with a 100 mu m-thick tape with a roughness R-a of 4.97 urn. At Reynolds numbers ranging from 210,000 to 380,000, the leading edge roughness decreases loss slightly. At Reynolds number of 210,000, the leading edge roughness reduces the size of the suction side laminar separation bubble and turbulence level in the turbulent boundary layer after reattachment. Thus, the leading edge roughness reduces displacement and momentum thicknesses as well as profile loss at Reynolds number of 210,000. However, the same leading edge roughness increases loss significantly for Re = 450,000 similar to 640,000. At Reynolds number of 640,000, the leading edge roughness decreases the magnitude of the favorable pressure gradient for axial chordwise locations less than 0.41 and induces turbulent separation for axial chordwise locations greater than 0.63, drastically increasing loss. Thus, roughness limited to the leading edge still has a profound effect on the compressor flow field.

ID ENDWALL; BLADE; TURBULENCE; CASCADE
AB Secondary flow losses were investigated experimentally in a linear cascade of high pressure turbine blades in a low speed wind tunnel. Periodic wakes were generated with moving rods upstream of the cascade to simulate the effect of wakes from upstream vanes in an engine. Velocities, turbulence levels and turbulence spectra were documented downstream of the wakes generated by the upstream rods and downstream of the cascade airfoils. Pressure distributions were documented on the airfoils at the midspan and near the tip. Total pressure loss through the passage was measured at the midspan and in the endwall boundary layer. Cases were documented with and without upstream wakes at a Reynolds number of 30,000 based on inlet velocity and axial chord. An additional case was acquired at Re=60,000 without wakes. The effects of wakes and Reynolds number on the pressure distribution on the airfoils were small. In the cases without wakes, total pressure losses were 27% higher at the lower Reynolds number due to thicker boundary layers. Upstream wakes cause an increase of about 80% in total pressure losses at the midspan and a 36% increase near the endwall. Much of this is due to the loss associated with the upstream wakes themselves, but with this direct effect subtracted the losses are still 20% higher in the case with wakes at the midspan with local increases comparable near the endwall.

The system is based primarily on SMS messaging technologies and either indigenous mobile phone service providers or mobile phone service brought in via cellular-on-wheels (COWs), UAVs, rapidly deployed towers, etc. End users use either their own cell phones, running a native SMS application, or low-cost phones that are distributed by a large non-governmental organization, such as UN OCHA. If a proprietary network is set up, SIM cards are distributed to end users to allow access to the network, or administrators will explicitly allow access via a phone's IMEI number or other access control methods.

AB Repetitive control (RC) is a form of control that specifically aims to eliminate the effects of periodic disturbances using knowledge of the disturbance period. It has applications in spacecraft for eliminating disturbances to fine pointing equipment from slight imbalance in reaction wheels or CMG's. In this paper, a spacecraft laser pointing test bed is used for experiments. In some RC applications the period can fluctuate, or the assessment of the period is course due to sampling effects, or the error frequency peak from the disturbance is somewhat wide. In such cases there is a need for control methods that are robust to imprecise knowledge of the disturbance period. This paper evaluates a new method of addressing this problem, by using multiple period repetitive control (MPRC) and making the multiple periods identical. This approach is compared in numeric simulations to the existing method in the literature, higher order repetitive control (HORC) with negative weights. Experimental results will be reported in another publication. In addition, it is shown how to make several other control approaches address the same problem, including matched basis function repetitive control and model predictive control. Advantages and disadvantages of each approach are determined.

AB A new high performance computing software applications package called the Search and Determine Integrated Environment (SADIE) is being jointly developed and refined by the Air Force and Naval Research Laboratories (AFRL and NRL) to automatically resolve uncorrelated tracks (UCTs) and build a more complete space object catalog for improved Space Situational Awareness (SSA). The motivation for SADIE is to respond to very challenging needs identified by and guidance received from Air Force Space Command (AFSPC) and other senior leaders to develop this technology to support the evolving Joint Space Operations Center (JSpOC) and Alternate Space Control Center (ASC2)-Dahlgren. The SADIE suite includes modification and integration of legacy applications and software components that include Search And Determine (SAD), Satellite Identification (SID), and Parallel Catalog (ParCat), as well as other utilities and scripts to enable end-to-end catalog building and maintenance in a parallel processing environment. SADIE is being developed to handle large catalog building challenges in all orbit regimes and includes the automatic processing of radar, fence, and optical data. Promising real data results are provided for the processing of low Earth radar and Air Force Space Surveillance System fence observations as well as Space Surveillance Telescope optical data.

ID MULTIPLE HYPOTHESIS TRACKING; TARGET TRACKING; ALGORITHM; FILTER
AB When observing satellites in an increasingly cluttered space environment, ambiguity in measurement association often arises. By using principles of probabilistic, or Bayesian, inference, we can assign numerical values of probability to the different possible associations. Several methods for handling ambiguous satellite observations are discussed, including Probabilistic Data Association (PDA) and Multiple Hypothesis Tracking (MHT). We present a comparison of these methods for a small number of observations and satellites, with a simplified motion and observation models. Filtering performance is characterized for four representative scenarios, including satellite breakups and conjunctions.

AB Uncertainties in a direction-finding sensor affect the determined orbit. In a radio-frequency interferometer, modeling only phase difference (timing) uncertainty with a normal distribution, the posterior probability density function of the direction is multimodal. We show that by treating the probability density function of the direction cosine as a discrete set of disconnected regions, or segments, corresponding to each mode, and computing within each mode a conventional mean and standard deviation, we can retain information that would be lost given a conventional treatment which is optimized for a unimodal result. With a corresponding generalization in other parts of the calculation, such as observation association and orbit determination, we may obtain not only improvement of results from a conventional antenna array, but the possibility that a less expensive, simplified array, that can still contribute valuable orbital knowledge, and, due to its lower cost, could enjoy more widespread deployment. We introduce and explain the notion of Multiple Mode Combinatorial Hypothesis Least Squares (MMCHLS), graphing the results obtained from synthesized observations, comparing with the known correct result, as an idea of how that generalization might proceed.

AB AlGaN/GaN power high electron mobility transistor (HEMT) performance is limited by current collapse and off-state gate and drain leakage current. A series of studies to improve these properties through optimized surface cleaning, as well as the implementation of novel materials, such as AlN and nanocrystalline diamond, is presented. Reduced leakage currents, degradation of dynamic ON-resistance, and current collapse ratio quantify improvement in HEMT performance. DC I-V measurements, pulsed I-V measurements, and a boost converter test circuit is used to validate these properties.

AB Institutional structures of professional career paths often support bread-winner-homemaker families, with a stay at home wife available full time to support the professional (and children), so the professional can devote complete energy and time to developing a career. This research examines how two partners in the same narrowly structured, fast track occupational culture such as those occurring for dual military officer couples shape how women and men negotiate decision making and life events. Data from interviews with 23 dual U.S. Navy officer couples build upon Becker and Moen's (1999) scaling back notions. With both spouses in these careers, placing limits on work is extremely difficult due to fast track cultures that demand higher status choices and structures that formally do not reliably consider collocations. Trading off occurs, but with distress due to the unique demands on two partners in the fast track culture, which means career death for some. Two partners in fast track careers may not yet have given up on two careers as many peers may have, but they lose a great deal, including time together and their desired number of children. But they ultimately posit individual choice rather than focusing on structural change. The pressured family life resulting is likely similar to that for partners in other narrowly structured, fast track cultures such as in law firms and academia.

AB The imaging, pointing, and tracking performance of precision optical systems are degraded by various disturbances which induce optical beam jitter. The present research proposes adaptive filter control methods for actively attenuating beam jitter using a fast steering mirror. Control loops with various structures of adaptive transversal filters are developed to suppress time-varying or uncertain jitter, and their characteristics and performances are compared. In particular, for situations when obtaining reference signals which are fully coherent with the disturbance is not possible, methods for incorporating multiple semi-coherent reference signals into the control law are developed. An index variable is defined to measure quality of various references signals, and a few signals are selected based on this index. The developed controllers are verified on a jitter control testbed, and experimental results show that the adaptive methods show superior performance in jitter attenuation over the conventional non-adaptive method.

AB Water submerged gas jets are characterized by the interplay of inertia and buoyancy forces and can exhibit diverse behaviors ranging from bubbly plumes to stable jets. In this work, direct measurements of the interfacial behavior of water-submerged gas jets, with Mach numbers ranging from subsonic to supersonic, were performed using high-speed digital photography and shadowgraphs. The results indicate that the jets have a preferential pinch-off position that can be attributed and correspond to the location of the maximum streamwise-velocity turbulence fluctuations. A new, experimentally determined jet penetration distance is proposed; the jetting length is taken as the jet length corresponding to a 99% probability of the gas-jet outer boundary being attached to the orifice during the sampling period. Using the shadowgraph analysis and this criterion, we determined that the electro-resistivity probe measurements, previously used to determine the jet penetration length, may be significantly biased. This is attributed to the inability of the probe measurements to distinguish between a continuous gas jet and advecting bubbles. In addition, based on a simple force-balance of the jet cross-section, we introduce a new scaling relationship for the jet penetration distance. This relationship shows that the jetting length scales with the square of the Froude number and compares well with the experimental observations. Finally, measurements of the gas jet boundary acceleration coupled with estimations of the internal gas jet velocity suggest that both Rayleigh-Taylor and Kelvin-Helmholtz mechanisms are nearly equally responsible for governing the jet boundary dynamics.

Let B-r,B- n(1 <= r <= n) be an n x n matrix of entries {a(j)(i)}, -r <= I <= r, 1 <= j <= r, with the remaining un-indexed entries all zeros. In this paper, generalizing a method of Mallik (1999) [5], we give the LU factorization and the inverse of the matrix B-r,B- n (if it exists). Our results are valid for an arbitrary square matrix (taking r = n), and so, we will give a new approach for computing the inverse of an invertible square matrix.

AB MS2 phage (MS2 empty set) is a coli phage, non-pathogenic to eukaryotic cells, which has been used as a simulant for viral biothreats, such as those causing smallpox and hemorrhagic fever. MS2 empty set consists of an icosahedral capsid, 28 nm in diameter, and a single stranded RNA genome; the viral capsid is composed of 180 copies of coat protein (CP). In this study, we isolated anti-MS2 empty set single domain antibodies (sdAbs) for the sensitive detection of the MS2 empty set. To achieve this, a first immune sdAb library was prepared from llamas immunized with purified coat protein and a second from animals immunized with MS2 empty set. By panning the two libraries against CP, MS2 empty set, or alternating between the two targets, anti-MS2 empty set and anti-CP sdAbs were selected, sequenced, and characterized for their binding affinity. Both direct binding assays and capture sandwich assays were performed on the MAGPIX platform. One of the best anti-MS2 empty set sdAb, Lib2CP12H, could detect MS2 empty set concentrations as low as 1.45 ng/mL (similar to 5.0E+6 pfu/mL), providing equivalent detection to conventional antibodies. This sdAb is thermally stable with a melting temperature around 60 degrees C and recovered 80% of its secondary structure after heat denaturation. Published by Elsevier Ltd.

AB Invasive pneumococcal disease (IPD) associated with Streptococcus pneumonia is a major public health problem worldwide for all age groups, including in Lebanon. Prevention through vaccination remains the most valuable tool to decrease the burden of disease. Pneumococcal conjugate vaccine 7 (PCV7), marketed internationally including in the Middle East and North Africa region for the prevention of IPD, was introduced in Lebanon in 2006, followed by PCV10 and PCV13 in 2010. However, none of these is currently part of the Extended Program of Immunization schedule and published data on IPD incidence, pneumococcal serotypes and vaccine coverage in the region are lacking. The Lebanese Inter-Hospital Pneumococcal Surveillance Program is a surveillance system set up to determine the burden of IPD and the prevalent serotypes responsible. The aim of this prospective 6-year study carried out in 78 hospitals throughout Lebanon was to obtain such data to help health authorities make informed decisions on the implementation of pneumococcal vaccination at the national level. A total of 257 isolates of culture-confirmed Streptococcus pneumoniae were evaluated. Considering all age groups, vaccine coverage was 41.4%, 53.9%, and 67.2% for PCV7, PCV10, and PCV13 serotypes, respectively; for patients <2, 2-5, and >60 years of age, PCV7 coverage was 50%, 51%, and 35%, respectively; PCV10 coverage was 53%, 74%, 45%, respectively; and PCV13 coverage was 63%, 80%, and 68%, respectively. Overall, 17.4% of these isolates were penicillin-G non-susceptible using the latest established breakpoints and mortality occurred in 23.5% of the patients with non-susceptible isolates. In addition, 10.9% of isolates were multi-drug-resistant. The highest mortality rates were observed in the eldest (>60 years of age) and youngest (<2 years of age) patients. The most prevalent invasive serotypes identified were those found in currently available pneumococcal conjugate vaccines, emphasizing the importance of implementing the vaccine in the routine immunization schedule at the national level. Continuation of current surveillance practices will help assess the impact of vaccine implementation on IPD epidemiology, serotype distribution and antibiotic resistance patterns.

AB Boundary layer separation control has been studied using vortex generator jets (VGJs) on a very high lift, low-pressure turbine airfoil. Experiments were done under low (0.6%) freestream turbulence conditions on a linear cascade in a low speed wind tunnel. Pressure surveys on the airfoil surface and downstream total pressure loss surveys were documented. Instantaneous velocity profile measurements were acquired in the suction surface boundary layer. Cases were considered at Reynolds numbers (based on the suction surface length and the nominal exit velocity from the cascade) of 25000 and 50000. Jet pulsing frequency and duty cycle were varied. In cases without flow control, the boundary layer separated and did not reattach. With the VGJs, separation control was achieved. At sufficiently high pulsing frequencies, separation control was possible with low jet velocities and 10% duty cycle. At lower frequencies, a 50% duty cycle helped by separating the disturbances associated with the jets turning on and turning off, thereby doubling the frequency of separation control events above the pulsing frequency. Phase averaged velocity profiles and wavelet spectra of the velocity show the VGJ disturbance causes the boundary layer to reattach, but that it can re-separate between disturbances. When the disturbances occur at high enough frequency, the time available for separation is reduced, and the separation bubble remains closed at all times. Published by Elsevier Ltd.

AB Background: Current efforts are underway to quantify the chemical concentration in a treated air space that elicits a spatial repellent (deterrent) response in a vector population. Such information will facilitate identifying the optimum active ingredient (AI) dosage and intervention coverage important for the development of spatial repellent tools -one of several novel strategies being evaluated for vector-borne disease control. This study reports initial findings from air sampling experiments conducted under field conditions to describe the relationship between air concentrations of repellent AIs and deterrent behavior in the dengue vector, Aedes aegypti.
Methods: Air samples were taken inside and outdoors of experimental huts located in Pu Tuey Village, Kanchanaburi Province, Thailand in conjunction with mosquito behavioral evaluations. A mark-release-recapture study design using interception traps was used to measure deterrency of Ae. aegypti against 0.00625% metofluthrin coils and DDT-treated fabric (2g/m2) within separate experimental trials. Sentinel mosquito cohorts were positioned adjacent to air sampling locations to monitor knock down responses to AI within the treated air space. Air samples were analyzed using two techniques: the U. S. Environmental Protection Agency (USEPA) Compendium Method TO-10A and thermal desorption (TD).
Results: Both the USEPA TO-10A and TD air sampling methods were able to detect and quantify volatized AIs under field conditions. Air samples indicated concentrations of both repellent chemicals below thresholds required for toxic responses (mortality) in mosquitoes. These concentrations elicited up to a 58% and 70% reduction in Ae. aegypti entry (i. e., deterrency) into treated experimental huts using metofluthrin coils and DDT-treated fabric, respectively. Minimal knock down was observed in sentinel mosquito cohorts positioned adjacent to air sampling locations during both chemical evaluations.
Conclusions: This study is the first to describe two air sampling methodologies that are appropriate for detecting and quantifying repellent chemicals within a treated air space during mosquito behavior evaluations. Results demonstrate that the quantity of AI detected by the mosquito vector, Ae. aegypti, that elicits repellency is far lower than that needed for toxicity. These findings have important implications for evaluation and optimization of new vector control tools that function through mosquito behavior modification as opposed to mortality.

AB A hybrid ion-neutral trap provides an ideal system to study collisional dynamics between ions and neutral atoms. This system provides a general cooling method that can be applied to species that do not have optically accessible transitions and can also potentially cool internal degrees of freedom. The long-range polarization potentials (V proportional to - alpha/r(4)) between ions and neutrals result in large scattering cross sections at cold temperatures, making the hybrid trap a favorable system for efficient sympathetic cooling of ions by collisions with neutral atoms. We present experimental evidence of sympathetic cooling of trapped Na+ ions, which are closed shell and therefore do not have a laser-induced atomic transition from the ground state, by equal-mass cold Na atoms in a magneto-optical trap.

AB A set of sensitivity experiments are performed with a two-way coupled and nested ocean-atmosphere forecasting system in order to deconvolve how dense phytoplankton stocks in a coastal embayment may impact thermal energy exchange processes. Monterey Bay simulations parameterizing solar shortwave transparency in the surface ocean as an invariant oligotrophic oceanic water type estimate consistently colder sea surface temperature (SST) than simulations utilizing more realistic, spatially varying shortwave attenuation terms based on satellite estimates of surface algal pigment concentration. These SST differences lead to an similar to 88% increase in the cumulative turbulent thermal energy transfer from the ocean to the atmosphere over the three month simulation period. The result is a warmer simulated atmospheric boundary layer with respective local air temperature differences approaching similar to 2 degrees C. This study suggests that the retention of shortwave solar flux by ocean flora may directly impact even short-term forecasts of coastal meteorological variables. Citation: Jolliff, J. K., T. A.

AB The synthesis and physical properties of cyanurate networks formed from two new tricyanate monomers, 1,3,5-tris[(4-cyanatophenylmethyl]benzene and 3,5-bis[(4-cyanatophenylmethyl)]phenylcyanate, are reported and compared to those of 1,1,1-tris[(4-cyanatophenyl)]ethane (also known as ESR-255). All three networks possessed somewhat different aromatic contents and cross-link densities; however, the thermochemical stability of these networks, as determined by TGA, was outstanding, with that of 1,3,5-tris[(4-cyanatophenylmethyl)]benzene being among the best known for organic cyanate esters despite its comparatively high segmental flexibility. Moreover, the moisture uptake of cured 1,3,5-tris[(4-cyanatophenylmethyl)]benzene, at 2.2% after 96 h immersed in 85 degrees C water, was comparatively low for a cyanate ester network with a glass transition temperature of 320 degrees C at full cure. When cured for 24 h at 210 degrees C, the dry glass transition temperatures of the networks ranged from 245 to 285 degrees C, while the wet glass transition temperatures ranged from 225 to 240 degrees C. The similarity in glass transition temperatures resulted from a lower extent of cure in the networks with more rigid segments. In essence, for networks with very high glass transition temperatures at full cure, the process conditions, rather than the rigidity of the network, determined the attainable glass transition temperature. Because networks with a higher extent of cure tend to exhibit slower long-term degradation, in this case, the networks with greater segment flexibility enabled superior performance despite exhibiting a lower glass transition temperature at full cure. These results illustrate that, in contrast to the prevailing heuristics for improving the performance of high-temperature thermosetting polymer networks, a more flexible network with a lower glass transition temperature at full cure can offer an optimal combination of thermomechanical and thermochemical performance.

AB Two dimensional crystal heterostructures are shown to possess a unique opportunity for nonlinear THz devices. In contrast to the oxide tunneling barrier, the uniformity of layered crystal insulators provides an ideal condition for tunneling barriers in the atomic scale. Numerical calculations based on a first-principles method clearly indicate the feasibility of diode operation with barriers as thin as two monolayers when placed between graphene-metal asymmetric electrodes. Further analysis predicts cut-off frequencies over 10 THz while maintaining strong nonlinearity for zero-bias rectification. Application to hot electron transistors is also examined, illustrating potentially superior performance in the frequency range inaccessible thus far. (C) 2012 American Institute of Physics.

TI Comparative Analysis of Hemagglutination Inhibition Titers Generated
Using Temporally Matched Serum and Plasma Samples
SO PLOS ONE
LA English
DT Article
ID INFLUENZA-VIRUS; IMMUNOGENICITY; ANTIBODIES; VACCINE
AB Influenza-specific hemaggluitination inhibition (HAI) antibody titer, an indicator of immunity to influenza, is often used to measure exposure to influenza in surveillance and immunogenicity studies. Traditionally, serum has been the specimen of choice for HAI assays, but a desire to reduce the amount of blood collected during studies and the availability of plasma in archived sample collections warrant the evaluation of plasma for HAI titer. Therefore, the relationship between serum and plasma HAI titer values is of great interest. Here, we compare HAI titers determined on temporally matched serum and plasma (citrated and heparinized) using influenza A and B viruses. Bland-Altman plots, McNemar's test, and geometric coefficient of variation were used respectively for evaluating agreement, correlation and variability in the serum-plasma titer results. We observed a high degree of agreement (80.5%-98.8%) and correlation (r = 0.796-0.964)in the serum and matched plasma titer values although plasma titers were generally lower than corresponding serum titers. Calculated seropositive (HAI >= 40) rates were higher using serum titers than with plasma titers, but seroconversion rates were unaffected by sample type. Stronger agreement and decreased variability in titers were seen between serum and citrated plasma than between serum and heparinized plasma. Overall, these data suggest that serum or plasma can be used in serodiagnostic HAI assays, but seropositive rates may be underestimated using plasma HAI titers. The type of anticoagulant present in plasma may affect HAI titer values and warrants further investigation. Citation: Defang GN, Martin NJ, Burgess TH, Millar EV, Pecenka LA, et al.

AB We have performed an analysis of the diffuse gamma-ray emission with the Fermi Large Area Telescope (LAT) in the Milky Way halo region, searching for a signal from dark matter annihilation or decay. In the absence of a robust dark matter signal, constraints are presented. We consider both gamma rays produced directly in the dark matter annihilation/decay and produced by inverse Compton scattering of the e(+)/e(-) produced in the annihilation/decay. Conservative limits are derived requiring that the dark matter signal does not exceed the observed diffuse gamma-ray emission. A second set of more stringent limits is derived based on modeling the foreground astrophysical diffuse emission using the GALPROP code. Uncertainties in the height of the diffusive cosmic-ray halo, the distribution of the cosmic-ray sources in the Galaxy, the index of the injection cosmic-ray electron spectrum, and the column density of the interstellar gas are taken into account using a profile likelihood formalism, while the parameters governing the cosmic-ray propagation have been derived from fits to local cosmic-ray data. The resulting limits impact the range of particle masses over which dark matter thermal production in the early universe is possible, and challenge the interpretation of the PAMELA/Fermi-LAT cosmic ray anomalies as the annihilation of dark matter.

AB The structure of non-force-free equilibrium magnetic flux ropes in an ambient medium of specified pressure p(a) is studied. A flux rope is a self-organized magnetized plasma structure consisting of a localized channel of electric current and the magnetic field arising from this current. An analytic method is developed to obtain one-dimensional equilibrium solutions satisfying c(-1) J x B - del p = 0 subject to the requirements that (1) all physical quantities be nonsingular and continuous, (2) pressure p(r) be physically admissible-real and non-negative, and (3) the magnetic field profile have "minimum complexity." The solutions are shown to be characterized by two parameters, B-t* = (B) over bar (t)/(8 pi p(a))(1/2) and B-p* = B-pa/(8 pi p(a))(1/2), where (B) over bar (t) is the toroidal (axial) field averaged over the cross-sectional radius a and B-pa is the poloidal (azimuthal) field at the edge of the current channel (r = a). The physical constraint on pressure defines equilibrium boundaries in the B-t*-B-p* space beyond which no physical solutions exist. The method is illustrated with a number of families of solutions governed by distinct physical constraints. The force-free limit with p(a) not equal 0 is investigated and is found to be characterized by plasma beta = infinity. The local Alfven speed V-A and plasma beta are computed. The results are scale-invariant.

AB We present results from an ongoing multiwavelength radial velocity (RV) survey of the Taurus-Auriga star-forming region as part of our effort to identify pre-main-sequence giant planet hosts. These 1-3 Myr old T Tauri stars present significant challenges to traditional RV surveys. The presence of strong magnetic fields gives rise to large, cool star spots. These spots introduce significant RV jitter which can mimic the velocity modulation from a planet-mass companion. To distinguish between spot-induced and planet-induced RV modulation, we conduct observations at similar to 6700 angstrom and similar to 2.3 mu m and measure the wavelength dependence (if any) in the RV amplitude. CSHELL observations of the known exoplanet host Gl 86 demonstrate our ability to detect not only hot Jupiters in the near-infrared but also secular trends from more distant companions. Observations of nine very young stars reveal a typical reduction in RV amplitude at the longer wavelengths by a factor of similar to 2-3. While we cannot confirm the presence of planets in this sample, three targets show different periodicities in the two wavelength regions. This suggests different physical mechanisms underlying the optical and the K-band variability.

AB GJ 581d is a potentially habitable super-Earth in the multiple system of exoplanets orbiting a nearby M dwarf. We investigate this planet's long-term dynamics with an emphasis on its probable final rotation states acquired via tidal interaction with the host. The published radial velocities for the star are re-analyzed with a benchmark planet detection algorithm to confirm that there is no evidence for the recently proposed two additional planets (f and g). Limiting the scope to the four originally detected planets, we assess the dynamical stability of the system and find bounded chaos in the orbital motion. For the planet d, the characteristic Lyapunov time is 38 yr. Long-term numerical integration reveals that the system of four planets is stable, with the eccentricity of the planet d changing quasi-periodically in a tight range around 0.27, and with its semimajor axis varying only a little. The spin-orbit interaction of GJ 581d with its host star is dominated by the tides exerted by the star on the planet. We model this interaction, assuming a terrestrial composition of the mantle. Besides the triaxiality-caused torque and the secular part of the tidal torque, which are conventionally included in the equation of motion, we also include the tidal torques' oscillating components. It turns out that, depending on the mantle temperature, the planet gets trapped into the 2: 1 or an even higher spin-orbit resonance. It is very improbable that the planet could have reached the 1: 1 resonance. This improves the possibility of the planet being suitable for sustained life.

AB We present a wide (8 degrees.5 x 6 degrees.7, 1050 x 825 kpc), deep (sigma(NHI) = 10(16.8)-10(17.5) cm(-2)) neutral hydrogen (H I) map of the M101 galaxy group. We identify two new Hi sources in the group environment, one an extremely low surface brightness (and hitherto unknown) dwarf galaxy, and the other a starless Hi cloud, possibly primordial in origin. Our data show that M101' s extended Hi envelope takes the form of a similar to 100 kpc long tidal loop or plume of Hi extending to the southwest of the galaxy. The plume has an Hi mass of similar to 10(8) M-circle dot and a peak column density of N-HI = 5 x 10(17) cm(-2), and while it rotates with the main body of M101, it shows kinematic peculiarities suggestive of a warp or flaring out of the rotation plane of the galaxy. We also find two new H I clouds near the plume with masses similar to 10(7) M-circle dot, similar to H I clouds seen in the M81/M82 group, and likely also tidal in nature. Comparing to deep optical imaging of the M101 group, neither the plume nor the clouds have any extended optical counterparts down to a limiting surface brightness of mu(B) = 29.5. We also trace Hi at intermediate velocities between M101 and NGC 5474, strengthening the case for a recent interaction between the two galaxies. The kinematically complex Hi structure in the M101 group, coupled with the optical morphology of M101 and its companions, suggests that the group is in a dynamically active state that is likely common for galaxies in group environments.

AB Reports of humpback whale (Megaptera novaeangliae) song chorusing occurring outside the breeding grounds are becoming more common, but song structure and underwater behavior of individual singers on feeding grounds and migration routes remain unknown. Here, ten humpback whales in the Western Antarctic Peninsula were tagged in May 2010 with non-invasive, suction-cup attached tags to study foraging ecology and acoustic behavior. Background song was identified on all ten records, but additionally, acoustic records of two whales showed intense and continuous singing, with a level of organization and structure approaching that of typical breeding ground song. The songs, produced either by the tagged animals or close associates, shared phrase types and theme structure with one another, and some song bouts lasted close to an hour. Dive behavior of tagged animals during the time of sound production showed song occurring during periods of active diving, sometimes to depths greater than 100 m. One tag record also contained song in the presence of feeding lunges identified from the behavioral sensors, indicating that mating displays occur in areas worthy of foraging. These data show behavioral flexibility as the humpbacks manage competing needs to continue to feed and to prepare for the breeding season during late fall. This may also signify an ability to engage in breeding activities outside of the traditional, warm water breeding ground locations.

AB Study Design. Survival analyses of a large cohort of published lumbar spine compression fatigue tests.
Objective. To produce the first large-scale evaluation of human lumbar spine tolerance to repetitive compressive loading and to evaluate and improve guidelines for human exposure to whole-body vibration and repeated mechanical shock environments.
Summary of Background Data. Several studies have examined the effects of compressive cyclic loading on the lumbar spine. However, no previous effort has coalesced these studies and produced an injury risk analysis with an expanded sample size. Guidelines have been developed for exposure limits to repetitive loading (e. g., ISO 2631-5), but there has been no large-scale verification of the standard against experimental data.
Methods. Survival analyses were performed using the results of 77 male and 28 female cadaveric spinal segment fatigue tests from 6 previously published studies. Segments were fixed at each end and exposed to axial cyclic compression. The effects of the number of cycles, load amplitude, sex, and age were examined through the use of survival analyses.
Results. Number of cycles, load amplitude, sex, and age all are significant factors in the likelihood of bony failure in the spinal column. Using a modification of the risk prediction parameter from ISO 2631-5, an injury risk model was developed, which relates risk of vertebral failure to repeated compressive loading. The model predicts lifetime risks less than 7% for industrial machinery exposure from axial compression alone. There was a 38% risk for a high-speed planing craft operator, consistent with epidemiological evidence.
Conclusion. A spinal fatigue model which predicts the risk of in vitro lumbar spinal failure within a narrow confidence interval has been developed. Age and sex were found to have significant effects on fatigue strength, with sex differences extending beyond those accounted for by endplate area disparities.

AB Background. Low bone mineral density (BMD) is common among patients infected with human immunodeficiency virus (HIV) and present in higher rates in black subjects. This study assessed vitamin D levels in HIV cases versus noninfected matched controls to determine if deficiency was associated with BMD and HIV clinical outcomes.
Methods. In total, 271 military beneficiaries with HIV underwent dual energy x-ray absorptiometry (DEXA) screening in 2001-2. Serum 25OH-vitamin D levels were determined using stored serum from the time of DEXA and 6-18 months prior. Two non-HIV-infected controls for each active duty case (n = 205) were matched on age, sex, race, zip code, and season using the Department of Defense Serum Repository (DoDSR). Vitamin D levels <20 ng/mL were considered deficient. HIV-related factors and clinical outcomes were assessed using data collected in the DoD HIV Natural History study.
Results. In total, 165 of 205 (80.5%) active duty HIV cases had 2 matched controls available. HIV cases had greater odds of for vitamin D deficiency (VDD) compared with controls (demographics adjusted paired data odds ratio [OR], 1.46, 95% confidence interval [CI], .87-2.45), but this was not statistically significant. Blacks were disproportionately deficient (P < .001) but not relative to HIV status or BMD. Low BMD was associated with typical risk factors (low body mass index and exercise levels, alcohol use); given limited available data the relationship between tenofovir exposure and VDD or low BMD could not be determined. Analysis of HIV-specific factors and outcomes such as exposure to antiretrovirals, HIV progression, hospitalizations, and death revealed no significant associations with vitamin D levels.
Conclusions. VDD was highly prevalent in black HIV-infected persons but did not explain the observed racial disparity in BMD. Vitamin D deficiency was not more common among HIV-infected persons, nor did it seem associated with HIV-related factors/clinical outcomes.

AB A novel processing technique was used to solution cast films of poly(benzimidazo benzophenanthroline), (BBL), and the novel ladder polymer poly(4-aza-benzimidazo benzophenanthroline) (Py-BBL), which were used as cathode materials in Type IV electroactive polymer-based electrochemical capacitors (EPECs). This new processing technique involves co-casting the polymer from solution with a room temperature ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIBTI). The new processing technique gave polymer films with superior transport properties and electrochemical stabilities, did not require a break-in period, and yielded higher charge capacity than the standard films. Co-cast films of BBL and Py-BBL were each incorporated into separate Type IV EPECs using poly(3,4-propylene dioxythiophene) (PProDOT) as the anode material. It was found that the PProDOT/BBL capacitors store, on average, about 50% more energy than a comparable PProDOT/Py-BBL EPEC. While PProDOT/BBL films have an energy density advantage at rates (power densities) less than 0.01 kW kg(-1), PProDOT/Py-BBL EPECs are capable of delivering higher energy than the BBL EPECs at rates greater than 0.01 kW kg(-1) (550 s per cycle). In fact, PProDOT/Py-BBL devices delivered more than ten times the energy density of PProDOT/BBL devices at 0.5 kW kg(-1) (50 s per cycle). The PProDOT/Py-BBL EPECs were cycled for 10,000 cycles at 65% depth of discharge and maintained 96% of the initial energy and power density, whereas the PProDOT/BBL EPECs were cycled under the same conditions and lost more than 35% of the initial energy and power density after only 2300 cycles.

AB Background: Lower respiratory tract infections (LRTI) are responsible for a considerable number of deaths among children, particularly in developing countries. In Egypt and the Middle East region, there is a lack of data regarding the viral causes of LRTI. In this study, we aimed to identify the relative prevalence of various respiratory viruses that contribute to LRTIs in young children. Although, nucleic acid-based methods have gained importance as a sensitive tool to determine the viral infections, their use is limited because of their prohibitive cost in low-income countries. Therefore, we applied three different laboratory methods, and presented the different virus prevalence patterns detected by each method.
Methods: We collected nasopharyngeal aspirate samples, demographic data and, clinical data from 450 children under five years of age who presented with LRTI at Abou El Reesh hospital in Cairo during a one-year period. To identify the viral causes of the LRTI we used direct fluorescence assay, real-time reverse-transcriptase polymerase chain reaction (rt-RT-PCR), and shell vial culture. We tested for eight major respiratory viruses.
Results: Two hundred sixty-nine patients (59.9%) had a viral infection, among which 10.8% had a co-infection with two or more viruses. By all three methods, respiratory syncytial virus (RSV) was the most predominant, and parainfluenza virus type 2 (HPIV-2), influenza B virus (FLUBV) were the least predominant. Other viral prevalence patterns differed according to the detection method used. The distribution of various viruses among different age groups and seasonal distribution of the viruses were also determined.
Conclusions: RSV and human adenovirus were the most common respiratory viruses detected by rt-RT-PCR. Co-infections were found to be frequent among children and the vast majority of co-infections were detected by nucleic acid-based detection assays.

TI Inferring dynamics from the wavenumber spectra of an eddying global
ocean model with embedded tides

ACCURACY
AB The slopes of the wavenumber spectra of sea surface height (SSH) and kinetic energy (KE) have been used to infer "interior" or surface quasi-geostrophic (QG or SQG) dynamics of the ocean. However, inspection of spectral slopes for altimeter SSH in the mesoscale band of 70 to 250 km shows much flatter slopes than the QG or SQG predictions over most of the ocean. Comparison of altimeter wavenumber spectra with spectra from an eddy resolving global ocean circulation model (the HYbrid Coordinate Ocean Model, HYCOM, at 1/12.5 degrees equatorial resolution), which has embedded tides, suggests that the flatter slopes of the altimeter SSH may arise from three possible sources: (1) presence of strong internal tides, (2) shift of the inertial sub-range to smaller scales and (3) altimeter noise. Artificially adding noise to the model tends to flatten the spectra for low KE regions. Near internal tide generating regions, spectral slopes in the presence of internal waves are much flatter than QG or SQG predictions. Separating the variability into high and low frequency (around periods of 2 days), then a different pattern emerges with a flat high-frequency wavenumber spectrum and a steeper low-frequency wavenumber spectrum. For low mesoscale KE, the inertial sub-range, defined by the nearly flat enstrophy band, moves to smaller scales and the mesoscale band of 70 to 250 km no longer represents the inertial sub-range. The model wavenumber spectra are consistent with QG and SQG theory when internal waves and inertial sub-range shifts are taken into consideration. Citation: Richman, J. G., B. K. Arbic, J. F.
