Real Time Quantitative 3-D Imaging of Diffusion Flame Species (1997)

A low-gravity environment, in space or ground-based facilities such as drop towers, provides a unique setting for study of combustion mechanisms. Understanding the physical phenomena controlling the ignition and spread of flames in microgravity has importance for space safety as well as better characterization of dynamical and chemical combustion processes which are normally masked by buoyancy and other gravity-related effects. Even the use of so-called 'limiting cases' or the construction of 1-D or 2-D models and experiments fail to make the analysis of combustion simultaneously simple and accurate. Ideally, to bridge the gap between chemistry and fluid mechanics in microgravity combustion, species concentrations and temperature profiles are needed throughout the flame. However, restrictions associated with performing measurements in reduced gravity, especially size and weight considerations, have generally limited microgravity combustion studies to the capture of flame emissions on film or video laser Schlieren imaging and (intrusive) temperature measurements using thermocouples. Given the development of detailed theoretical models, more sophisticated studies are needed to provide the kind of quantitative data necessary to characterize the properties of microgravity combustion processes as well as provide accurate feedback to improve the predictive capabilities of the computational models. While there have been a myriad of fluid mechanical visualization studies in microgravity combustion, little experimental work has been completed to obtain reactant and product concentrations within a microgravity flame. This is largely due to the fact that traditional sampling methods (quenching microprobes using GC and/or mass spec analysis) are too heavy, slow, and cumbersome for microgravity experiments. Non-intrusive optical spectroscopic techniques have - up until now - also required excessively bulky, power hungry equipment. However, with the advent of near-IR diode lasers, the possibility now exists to obtain reactant and product concentrations and temperatures non-intrusively in microgravity combustion studies. Over the past ten years, Southwest Sciences has focused its research on the high sensitivity, quantitative detection of gas phase species using diode lasers. Our research approach combines three innovations in an experimental system resulting in a new capability for nonintrusive measurement of major combustion species. FM spectroscopy or high frequency Wavelength Modulation Spectroscopy (WMS) have recently been applied to sensitive absorption measurements at Southwest Sciences and in other laboratories using GaAlAs or InGaAsP diode lasers in the visible or near-infrared as well as lead-salt lasers in the mid-infrared spectral region. Because these lasers exhibit essentially no source noise at the high detection frequencies employed with this technique, the achievement of sensitivity approaching the detector shot noise limit is possible.
Risk of esophageal cancer following radiotherapy for Hodgkin lymphoma (2014)

Advances in Hodgkin lymphoma (HL) treatment have dramatically improved prognosis, with 5-year relative survival now over 80% in the United States (US) and Europe. However, subsequent malignancies, often occurring as late adverse effects of treatment, are a leading cause of morbidity and mortality
Some Volatile Components ofVitis ViniferaVariety Cabernet Sauvignon Wine (1980)

A 170-liter sample of 1975 Monterey County Cabernet Sauvignon wine of intense aroma was extracted with successive portions of CH<sub>2</sub>Cl<sub>2</sub>. After neutralization of the acids in the extracts, drying, and removal of the solvent, the essence was analyzed by gas chromatography, coupled gas chromatography-mass spectrometry, and Kovats9 indices. Of particular interest among the 40 compounds identified were <i>cis</i>-2-hexen-1-ol, <i>cis</i>-3-hexen-l-ol, styrene, phenylacetaldehyde, ethyl furoate, diethyl maleate, diethyl malonate, 1,1,6-trimethyl-1,2-dihydronaphthalene, and ethyl cinnamate. 2-Methoxy-3-isobutyl pyrazine could not be identified in the extracts from the wine, nor in extracts when the wine had been made strongly basic and reextracted.
Genotoxic effects of two-generational selenium deficiency in mouse somatic and testicular cells (2014)

Many studies have investigated genotoxic effects of high Se diets but very few have addressed the genotoxicity of Se deprivation and its consequences in germ cells and none in somatic cells. To address these data gaps, C57BL/6 male mice were subjected to Se deprivation starting in the parental generation, i.e. before conception. Mice were given a diet of either low (0.01mg Se/kg diet) or normal (0.23mg Se/kg diet) Se content. Ogg1-deficient (Ogg1 (-/-) ) mice were used as a sensitive model towards oxidative stress due to their reduced capacity to repair oxidised purines. Ogg1 (-/-) mice also mimic the repair characteristics of human post-meiotic male germ cells which have a reduced ability to repair such lesions. The genotoxicity of Se deficiency was addressed by measuring DNA lesions with the alkaline single cell gel electrophoresis (+ Fpg to detect oxidised DNA lesions) in somatic cells (nucleated blood cells and lung cells) and male germ cells (testicular cells). Total Se concentration in liver and GPx activity in plasma and testicular cells were measured. Gene mutation was evaluated by an erythrocyte-based Pig-a assay. We found that Se deprivation of F1 from their conception and until early adulthood led to the induction of DNA lesions in testicular and lung cells expressed as significantly increased levels of DNA lesions, irrespective of the mouse genotype. In blood cells, Se levels did not appear to affect DNA lesions or mutant cell frequencies. The results suggest that the testis was the most sensitive tissue. Thus, genotoxicity induced by the low Se diet in the spermatozoal genome has potential implications for the offspring.
Observation of the Resonant Character of theZ(4430)−State (2014)

Resonant structures in B^{0}→ψ^{'}π^{-}K^{+} decays are analyzed by performing a four-dimensional fit of the decay amplitude, using pp collision data corresponding to 3 fb^{-1} collected with the LHCb detector. The data cannot be described with K^{+}π^{-} resonances alone, which is confirmed with a model-independent approach. A highly significant Z(4430)^{-}→ψ^{'}π^{-} component is required, thus confirming the existence of this state. The observed evolution of the Z(4430)^{-} amplitude with the ψ^{'}π^{-} mass establishes the resonant nature of this particle. The mass and width measurements are substantially improved. The spin parity is determined unambiguously to be 1^{+}.

Analysis of optical fiber failures under bending and high power (2004)

The failure of tightly bent optical fiber under high optical power is observed dynamically with fine time resolution and explained in terms of the behavior of the polymer coating and underlying glass. An abrupt rise in coating temperature stimulates the viscoelastic deformation of the glass. The abrupt bending of the glass is explained by the ability of highly quenched silica to deform at low temperatures. There is no evidence of thermal runaway of the glass core. Coating decomposition is self limiting with no visible flame.
Scalable MPI-3.0 RMA on the Blue Gene/Q Supercomputer (2014)

The MPI Forum has ratified extensions to MPI RMA with a new flexible and high performance passive target synchronization mechanism, new calls for window allocation and atomic operations executed on remote windows. In this paper, we explore an implementation of this new MPI-3.0 RMA interface on the Blue Gene/Q machine with performance results. We take advantage of the one-sided RDMA get and put operations available on the BG/Q machine. We use various micro benchmarks to show performance improvements of MPI-3.0 RMA over MPI-2.2 RMA. We also use the 2D stencil and 3D FFT benchmarks to compare MPI-3.0 RMA with MPI point to point communication. Microbenchmark performance results show MPI-3.0 RMA has lower latency than MPI-2.2 RMA, while application benchmarks show that MPI-3.0 RMA has comparable performance to MPI point-to-point communication.

Coherent equalization for underwater acoustic communications: A performance evaluation of adaptive MMSE and time-reversal techniques (2002)

A simple analytical expression is presented for evaluating and comparing the performance of channel-estimate-based coherent equalizers. A channel-estimate-based equalizer is one whose filter coefficients are calculated as a function of an explicit estimate of the acoustic channel impulse response. This is in contrast to a direct adaptation equalizer whose coefficients are calculated directly as the solution to a data estimation error minimization problem. The equalizer performance expression is different from other commonly used expressions because it is formulated from the viewpoint of the estimate of the channel impulse response rather than the actual channel impulse response. The expression allows the dependence of the performance of coherent equalizers on channel complexity and the quality of the channel estimate to be separately evaluated. The expression is used to evaluate and compare the performance of adaptive MMSE and time-reversal equalizers. [Work supported by ONR Ocean Acoustics.]
Hydrogen diffusion behavior in CH4N-molecularion-implanted wafers for three-dimensional stacked CMOS image sensors (2022)

In this study, the diffusion behavior of hydrogen in a CH4N-molecular-ion-implanted epitaxial wafer was investegated by reaction kinetic analysis. Two hydrogen-trapping sites, carbon aggregate and end of range (EOR) defects, were formed in the CH4N-implanted region. The C-H<inf>2</inf> binding state was formed in the carbon aggregate region. On the other hand, the N-H binding state was formed in the EOR defect region. This result indicates that CH4N-molecular-ion-implanted epitaxial wafers contribute to the reduction in D<inf>it</inf> at the SiO<inf>2</inf>/Si interface due to hydrogen desorption from the CH4N-implanted region during heat treatment in the device process.
A Non-Fickian Mixing Model for Stratified Turbulent Flows (2010)

Abstract : The long term goal of this project is to develop a better understanding of oceanic processes in the range of 100 m to 10 km, in the so-called submesoscale range. In particular, it is important to explore and find out whether and what type of submesoscale instabilities exist, how they are connected to both larger scale and smaller scale motions, and to what extent they influence transport processes in the ocean. Another important objective of this project is to test how well subgrid-scale (SGS) models for large eddy simulations (LES) work in the presence of backward energy cascade that may be characteristic in submesoscale motions. A long term objective of this effort would be to improve the predictive skill of the Navy numerical models for submesoscale transport in the ocean. My main objective has been to model upper ocean mixed layer instabilities, investigate their behavior and try to develop sampling strategies using synthetic drifters and tracers prior to the first LatMix cruises. In addition, modeling help with data analysis is planned. The work is based on LES using the non-hydrostatic spectral element model Nek5000 as well as field data. Also, software has been developed in order to automatically download and make available MODIS raw SST data over the selected region in the first LatMix cruise.
An Analytic Model for the Dielectric Function of Au, Ag, and their Alloys (2013)

An analytical model for the prediction of the dielectric properties of gold–silver alloys is developed. This multi‐parametric model is a modification of the usual Drude–Lorentz model that takes into account the band structure of the metals. It is fitted by a genetic algorithm to the dielectric function of thin alloy films of different gold–silver ratio obtained by ellipsometry. The model is validated for arbitrary alloy compositions by comparing the experimental extinction spectra of alloy nanoparticles with the spectra predicted by Mie theory.
Design of high directivity compact parasitic array for beam-steering applications (2015)

In this paper, two synthesis methods to design directive and compact parasitic antenna arrays with beam-steering capabilities are compared. The two methods are used to calculate the complex excitation coefficients associated to each array element needed to synthetize the antenna radiation pattern in a given direction. The analysis is principally focused on the antenna directivity and has been validated using a nine-element compact array at 1.75 GHz. The antenna is composed of nine monopoles (length 0.21λ), with only one driven element connected to a transceiver. This element is surrounded by eight parasitic monopoles arranged on a finite circular ground plane with a radius of 0.6λ and forming a circular (radius 0.1λ) array. The antenna has been prototyped and evaluated in a radio anechoic chamber. The measurement results are in excellent agreement with full-wave electromagnetic simulations.
Relationship between liquid crystalline phase stability and ingredient composition in liquid crystal oil–water emulsion (2016)

In this study, we postulated that the optical retardation magnitude could be used to evaluate the stability of the LC phase through the Mueller matrix polarimeter method in LC emulsion. In addition, we found that the increase of cetearyl alcohol concentration induced the more periodic dense lattice structure in crystalline phase of LC lamellae and the sorbitan olivate was relatively more responsible for higher ordering in LC phase compared to C12–20 alkyl glucoside in terms of molecular parallel packing on the basis of the optical retardation magnitude. Furthermore, it was confirmed that the LC emulsion had higher skin barrier function owing to lower TEWL and higher reflectance than ordinary emulsion on human skin and maintained a uniform phase without phase separation for 8 weeks.
Branched dipole array applicator for superficial hyperthermia system (2012)

The enhanced applicator for superficial hyperthermia system is presented. The applicator is composed with branched dipole array to heat the human skin region uniformly and effectively. The branched dipole element is designed to be operated at 433 MHz and has branched arm and matching structure. Two types of the 4 × 4 array for applicator are demonstrated on human body model and the enhanced uniformity of SAR and temperature distribution is shown in lattice array type. The temperature distribution by the lattice array is measured on the solid human phantom and compared with simulation.
Content-adaptive lenticular prints (2013)

Lenticular prints are a popular medium for producing automultiscopic glasses-free 3D images. The light field emitted by such prints has a fixed spatial and angular resolution. We increase both perceived angular and spatial resolution by modifying the lenslet array to better match the content of a given light field. Our optimization algorithm analyzes the input light field and computes an optimal lenslet size, shape, and arrangement that best matches the input light field given a set of output parameters. The resulting emitted light field shows higher detail and smoother motion parallax compared to fixed-size lens arrays. We demonstrate our technique using rendered simulations and by 3D printing lens arrays, and we validate our approach in simulation with a user study.
Interleukin 2 mediates stimulation of complement C3 biosynthesis in human proximal tubular epithelial cells. (1991)

Previous reports have suggested the production of complement components C4, C2, and factor B by renal tissue. However, the cells involved in production of complement have not been identified. In this study metabolic labeling experiments demonstrated that human proximal tubular epithelial cells (PTEC) synthesize a 180-kD precursor of C3 that is secreted after proteolytic cleavage into a disulphide linked two-chain molecule as found in plasma. C3 present in culture supernatants of PTEC was functionally active, however, during the culture period there was a partial inactivation of the C3 molecule as assessed by hemolytic titration. Recombinant IL-2 enhances the rate of C3 synthesis in a dose-dependent manner reaching maximal stimulation at doses of 200-400 U/ml IL-2. Northern blot analysis demonstrated a 5.2-kb C3 mRNA species present in PTEC that was increased within 24 h of IL-2 treatment. IL-2-induced enhancement of C3 production by PTEC could be neutralized with specific antibodies to IL-2. This study demonstrates that C3 synthesis in PTEC is upregulated by IL-2, the major cytokine produced by activated T cells.
Biotransformation of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) by a prospective consortium and its most effective isolate Serratia marcescens (1997)

The biotransformation of hexahydro-1,3,5-trinitro-1,3,5 triazine (RDX) has been observed in liquid culture by a consortium of bacteria found in horse manure. Five types of bacteria were found to predominate in the consortium and were isolated. The most effective of these isolates at transforming RDX was Serratia marcescens. The biotransformation of RDX by all of these bacteria was found to occur only in the anoxic stationary phase. The process of bacterial growth and RDX biotransformation was quantified for the purpose of developing a predictive type model. Cell growth was assumed to follow Monod kinetics. All of the aerobic and anoxic growth parameters were determined: micro(max), K(s), and Y(x/s). RDX was found to competitively inhibit cell growth in both atmospheres. Degradation of RDX by Serratia marcescens was found to proceed through the stepwise reduction of the three nitro groups to nitroso groups. Each of these reductions was found to be first order in both component and cell concentrations. The degradation rate constant for the first step in this reduction process by the consortium was 0.022 L/g cells . h compared to 0.033 L/g cells . h for the most efficient isolate.

A phase 3 study of a short, two dose regimen of an investigational Hepatitis B vaccine (2010)

Background: Achieving rapid protection against hepatitis B can be critical for travellers. HBsAg-ISS (HEPLISAV™) is an investigational vaccine containing Hepatitis B surface antigen (HBsAg) and 1018 Immunostimulatory Sequence (ISS), a Toll-like Receptor 9 (TLR9) agonist adjuvant. A Phase 3 study of subjects 18-55 years of age demonstrated non-inferiority of a short, 2 dose regimen of HBsAg-ISS to a 3 dose regimen of a licensed vaccine. This analysis in subjects >40 years of age compares the seroprotection rate (SPR), measured by antibody to HBsAg [anti-HBsAg] ≥10 mIU/mL, and anti-HBsAg geometric mean concentration (GMC) of HBsAg-ISS with licensed vaccine (Engerix-B, 20 mcg). This study demonstrated that the SPR of a short, 2 dose regimen of HBsAg-ISS in subjects 18-55 and in subjects over 40 is superior to the standard regimen of Engerix-B. This vaccine could provide a better solution for clinicians needing rapid, safe and effective protection against hepatitis B disease for travelers. Methods: A randomized observer-blind study comparing 2 doses of HBsAg-ISS at months 0 and 1 with saline placebo at month 6 to 3 doses of licensed vaccine at months 0, 1, and 6. Anti-HBsAg were measured at months 0, 1, 2, 3, 6, and 7. Safety, including local and systemic reactogenicity and adverse events was assessed. Results: 2101 subjects, including 1188 subjects over age 40, were included in the per-protocol analysis in a 3:1 randomization of HBsAg-ISS to Engerix-B. The primary endpoint SPR for all subjects was statistically significantly higher for HBsAg-ISS (95% at month 3) vs. Engerix-B (81% at month 7) [p < 0.0001]. For subjects over age 40 the primary endpoint SPR was 92% for HBsAg-ISS and 75% for Engerix-B) [p < 0.0001]; the GMC (mIU/mL) at month 7 was 236 for HBsAg-ISS and 218 for Engerix-B. HBsAg-ISS was safe, well-tolerated and comparable to Engerix-B with regard to local and systemic adverse events and serious adverse events. Two cases of ANCA-associated vasculitis were observed; one in an HBsAg-ISS subject and one in an Engerix-B subject. A review of AEs potentially associated with autoimmune conditions revealed no difference between groups. Conclusion: This study demonstrated that the SPR of a short, 2 dose regimen of HBsAg-ISS in subjects 18-55 and in subjects over 40 is superior to the standard regimen of Engerix-B. This vaccine could provide a better solution for clinicians needing rapid and safe protection against hepatitis B disease for travelers.
