Outdoor operation of GaInP/GaAs/Ge triple junction concentrator solar cells up to 1000 suns (2003)

Results from GaInP/GaAs/Ge, triple-junction concentrator solar cells of larger area than what is typically reported are presented for outdoor measurements up to 1000 suns. The IV characteristics of solar cell assemblies measured under steady illumination at various concentration levels are reported. For a cell aperture area of 0.605/spl times/0.605 cm/sup 2/, the efficiency reached 34.2% at 161 suns and is in close agreement with 33.4% at 52 suns measured by the HIPSS at NREL for cells of the same type and size. Near 1000 suns, the outdoor efficiency is 27.88% with fill factor of 77.7%. The dependence of the V/sub oc/ on concentration is linear from the data obtained from the HIPSS and nonlinear, specifically at higher concentration levels, for the outdoor tests. Their different V/sub oc/ behavior with concentration is due to heat effects. All outdoors test results showed no cell failures even as high as 1000 suns.
A Discrete and Distributed Steady Blowing Application on a High Reynolds Number Semispan Supercritical Wing Configuration (2018)

The FAST-MAC circulation control model was modified to test an array of steady and unsteady actuators at realistic flight Reynolds numbers in the National Transonic Facility at the NASA Langley Research Center. Previous experiments in the FAST-MAC test series used a fullspan tapered slot, and that configuration is used as a baseline for performance and weight flow requirements. The goal of the latest experiment was to reduce the weight flow required to achieve comparable performance established by the baseline FAST-MAC data. Thirty-nine interchangeable actuator cartridges of various designs were mounted into the FAST-MAC model where the exiting jet was directed over a 15% chord simple hinged-flap. These two types of actuators were fabricated using rapid prototype techniques and their design performance was optimized for a transonic cruise configuration having a 0 flap deflection. The steady actuators were found to provide an off-design drag reduction of 5.5%, nearly equaling the drag reduction of the fullspan tapered slot configuration, but with a 69% weight flow reduction. This weight flow savings is similar to the sweeping jet actuators, but with better drag performance.
Effect of Repositioning Aids and Patient Weight on Biomechanical Stresses When Repositioning Patients in Bed (2020)

To safely move dependent patients, a robust solution requires mechanical lifts and may utilize air-assisted transfer devices for patient transfers.
Anticoagulation following mitral valve repair (2020)

Our analysis showed that postoperative warfarin use was associated with an overall reduced composite of bleeding and thromboembolic incidents and superior long-term survival. These findings suggest that anticoagulation with warfarin following mitral valve repair may be a safe and effective means for avoiding postoperative complications and that a large prospective randomized clinical trial is warranted.
The UV and visible spectra of chlorine peroxide: Constraining the atmospheric photolysis rate (2014)

Abstract The photolysis of chlorine peroxide (ClOOCl) is a key chemical step in the depletion of polar stratospheric ozone. As such, precise measurements of the absorption cross sections for ClOOCl are required. In this paper we provide two critical pieces of laboratory data with which to constrain the rate of ozone depletion. First, we provide an optically pure ClOOCl spectrum in the photolytically important UV wavelength region (200–350 nm). Second, we provide the first ever measurement of the ClOOCl spectrum in the visible region (509–536 nm) conclusively demonstrating the photolysis of ClOOCl to be negligible in this spectral region. The visible measurement is important because it can be used to anchor other previously recorded UV spectra and hence reduce the uncertainty in the ClOOCl photolysis rate. The calculated photolysis rate from this study indicates that the current models of stratospheric ozone depletion are correct.
Semi-tied covariance matrices (2002)

A standard problem in many classification tasks is how to model feature vectors whose elements are highly correlated. If multi-variate Gaussian distributions are used to model the data then they must have full covariance matrices to accurately do so. This requires a large number of parameters per distribution which restricts the number of distributions that may be robustly estimated, particularly when high dimensional feature vectors are required. This paper describes an alternative to full covariance matrices in these situations. An approximate full covariance matrix is used. The covariance matrix is now split into two elements, one full and one diagonal, which may be tied at completely separate levels. Typically, the full elements are extensively tied, resulting in only a small increase in the number of parameters compared to the diagonal case. Thus dramatically increasing the number of distributions that may be robustly estimated. Simple iterative re-estimation formulae for all the parameters within the standard EM framework are presented. On a large vocabulary speech recognition task a 10% reduction in word error rate over a standard system was achieved.

Conformational polymorphism is exploited as a means to assign cis-trans and trans-trans conformations of an oligothiophene backbone using solid-state IR spectroscopy.
Use of specific dyes in the detection of antimicrobial compounds from crude plant extracts using a thin layer chromatography agar overlay technique (1995)

Abstract An improved bioautographic agar overlay method was developed for the detection of antimicrobial compounds from crude plant extracts using phenol red and a tetrazolium compound as dyes to improve resolution. This method worked successfully with a wide variety of microorganisms including a number of Gram‐positive and Gram‐negative bacteria and fungi. Phenol red and the test organisms were incorporated directly into nutrient agar that was overlayed onto a thin layer chromatogram of plant extracts. In the case of bacteria, after spraying with thiazolyl blue (methylthiazolyltetrazolium chloride), dark red coloured inhibition zones appeared against blue background. Satisfactory results were obtained even with those compounds which were present in very small quantities. This method proved to be useful for activity‐guided fractionation or for target‐directed isolation of the active constituents of plants.
Catalytic asymmetric epoxidation of stilbene using a chiral salen complex immobilized in Mn-exchanged Al-MCM-41 (2000)

Manganese-exchanged Al-MCM-41 modified by the chiral salen ligand [(R,R)-(−)-N,N′-bis(3,5-di-tert-butylsalicylidene)cyclohexane-1,2-diamine] can be used as an enantioselective heterogeneous epoxidation catalyst using iodosyl benzene as oxygen donor. Epoxidation of (Z)- and (E)-stilbene is studied in detail and experiments are described that demonstrate that the reaction is wholly catalysed heterogeneously. Similar enantioselectivity is observed for the oxidation of (Z)-stilbene to the (E)-epoxide using homogeneous (77.5% ee) or heterogeneous (70% ee) catalysts. The effect of temperature, solvents and donor ligands on the yield and enantioselection are discussed.
Advanced development process for ultrafine photoresist patterns (1993)

Addition of appropriate surfactant to developer will improve wettability of the developer, thus promoting uniformity of dissolution of exposed photoresist. Surface smoothness of the Si substrate is also improved when developer contains surfactant. The only disadvantage is that surfactant is adsorbed onto the wafer surface; however, it can be removed by a Pt-H/sub 2/O/sub 2/ treatment without degrading the photoresist pattern. The optimal tetramethylammonium hydroxide (TMAH) concentration in the developer was investigated by measuring the developing selectivity of the photoresist against various TMAH concentration levels. The developing selectivity is considered to directly affect the photoresist profile and resolution in the development process.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Characterization of a 450-km-baseline GPS Carrier-Phase Link using an Optical Fiber Link (2014)

Intercontinental frequency comparisons require satellite based techniques. We characterize a GPS carrier phase link with a baseline of 450 km using a long-distance phase-stabilized optical fiber link. Active hydrogen masers at both ends are compared via the GPS link and, via optical frequency combs at both ends, through the 920 km fiber link simultaneously. This technique allows us to independently assess the instability and accuracy of the GPS link with sub 1 × 10−15 resolution.
Low-complexity ultrawideband transceiver with compatibility to multiband-OFDM (2004)

We present a low-complexity transceiver for ultrawideband communications with moderate (1-15 Mbit/s) data rate. This transceiver is based on time-frequency-interleaved frequency-shift-keying (TF-FSK), and shows a high degree of compatibility with multiband-OFDM, the currently envisioned standard for high-data-rate (>100 Mbit/s) UWB communications. We show that for dual-mode devices, the major part of the multiband-OFDM transceiver can be reused for the TF-FSK transceiver. We also study the performance of this transceiver in (standardized) UWB channels, and find that, depending on the data rate, coverage ranges of up to 30 m (with LOS connection) are possible.

A 32kb memory is presented with an Ultra Low Voltage optimized 10 transistors bitcell designed to withstand an extended voltage range from 1.2V down to 0.35V, achieving 1.77pJ low energy access. A validation circuit was fabricated in 65nm CMOS and exhibits wafer level yield above 95% at 0.4V, 1MHz. Packaged parts show 0.32V minimum voltage at 490kHz and up to 17X energy gain per operation. The memory terrestrial radiation Soft Error Rate was characterized with no multibit errors reported, enabling future medical appplications radiation reliability through bit-interleaving combined with error correcting code.
Development of metastatic and non‐metastatic tumor lines from a patient's prostate cancer specimen—identification of a small subpopulation with metastatic potential in the primary tumor (2010)

The results indicate that in primary prostate tumors metastatic potential can be confined to a minority of cancer cells. Subrenal capsule xenograft methodology can be used to dissect heterogeneous cancer cells in a patient's primary tumor and sublines derived from such cells provide valuable tools for investigating mechanisms underlying prostate cancer metastasis.
Selective differential ammonia gas sensor based on N‐doped SWCNT films (2011)

Abstract The sensing performance of a micro‐sensor based on a thick film of nitrogen‐doped single‐walled carbon nanotube (SWCNTs) is compared to a pristine SWCNTs film. Transfer length method analysis is used to extract the film sheet resistance from electrical measurements and reveals that the gas sensing mechanism is mainly attributed to the charge transfer between gas molecules and SWCNTs. We demonstrate that the sensitivity to NH 3 can be improved by using a sensor based N‐doped SWCNTs films while the sensitivity to NO 2 and water vapour is unmodified. These unique gas‐sensing properties can be used to develop a new NH 3 ‐selective differential gas sensor.
Electrical resistivity (4K to 2100K) of annealed vapor growth carbon fibers (1987)

Carbon fibers have been grown from methane gas, on iron seeded substrates at 1370 K, and subsequently annealed to a series of temperatures between 2800 K and 3475 K. The subsequent measurement of the electrical resistivity are reported as a function of temperature from 4 K to 2100 K. The two band model for the resistivity of graphite is well fit to the data, and results in physically reasonable parameters of the fits. The resistivity vs temperature results for two boron doped fibers are reported as well. The product of the resistivity times density for these fibers is lower than that product for any refractory metal, for temperatures above about 1000 K, suggesting the usefulness of these fibers as high temperature materials in space applications.
Abstract LB-27: Dissecting signaling transduction network to infer master regulators of non small cell lung cancer (2011)

Abstract Abstract The dissection of signal transduction networks is lagging significantly with respect to their transcriptional and protein-complex counterparts. Innovative use of multiplex and microarray-based approaches, where multiple antibodies can be used to probe an ensemble of phosphoproteins, is starting to become sufficiently mature to allow characterization of small pathways. Yet, this is still far from providing an unbiased, genome-wide view of signal-transduction processes. Using data from the first genome-wide profiling of phosphopeptide abundance in normal and tumor related lung tissue1, we have designed a novel algorithm, pARACNe, to generate an unbiased, genome-wide network representing tyrosine kinase signal transduction pathways. Specifically, pARACNe was used to infer tyrosine kinase substrates in non-small cell lung cancer (NSCLC) from tandem mass-spec abundance profiling of phosphotyrosine enriched peptides from ∼250 samples derived from primary tumors, cell lines, and normal lung tissue. SILAC validation of EGFR, MET and ALK substrates, confirmed &amp;gt;80% of the pARACNe inferred interactions. Further analysis of large-scale NSCLC microarray expression profile data, using the MINDy algorithm2, showed significant convergence between the signal transduction pathways inferred by proteomics and gene expression based methods. The availability of an accurate NSCLC Tyrosine Kinase Interaction Network (TKIN) has significant implications for our ability to elucidate master regulators of oncogenesis and tumor progression and for the identification and prioritization of druggable targets. We used the MARINa algorithm and the TKIN to infer a complete repertoire of master regulator (MRs) kinases of 46 cell lines. Initial validation shows that the method could recapitulate both cancer specific MRs, such as EGFR, as well as cell line specific ones, such as ALK and PTK2 in H2228 cells. Follow up experimental assays have shown that the PTK2, which is active in tumor-related but not in normal cells, is required for H2228 cell viability and may constitute a novel oncogene addiction in NSCLC and a candidate therapeutic target. The TKI suggests that current pathway models are incomplete and sets the stage for quantitative, network-based methods to identify key regulators of physiologic and pathologic cell phenotypes.

Detection of labelled RNA species by contact hybridization (1979)

An improved contact hybridization technique for the analysis of labelled RNA species is presented. The method combines high sensitivity of detection with the high resolution of polyacrylamide gel electrophoresis and should be especially useful for the characterization of transient RNA precursor molecules. Its application to gene mapping is illustrated.
Class I MHC molecules on hematopoietic cells can support intrathymic positive selection of T cell receptor transgenic T cells (1999)

The identity of cells that mediate positive selection of CD8(+) T cells was investigated in two T cell receptor (TCR) transgenic systems. Irradiated beta(2)-microglobulin mutant mice or mice with mutations in both the K(b) and D(b) genes were repopulated with fetal liver cells from class I(+) TCR transgenic mice. In the case of the 2C TCR, mature transgene-expressing CD8(+) T cells appeared in the thymuses of the chimeras and in larger numbers in the peripheral lymphoid organs. These CD8(+) T cells were functional, exhibited a naive, resting phenotype, and were mostly thymus-dependent. Their development depended on donor cell class I expression. These results establish that thymic hematopoietic cells can direct positive selection of CD8(+) T cells expressing a conventional TCR. In contrast, no significant development of HY (male antigen)-TCR(+) CD8(+) T cells was observed in class I(+) into class I-deficient chimeras. These data suggest that successful positive selection directed by hematopoietic cells depends on specific properties of the TCR or its thymic ligands. The possibility that hematopoietic cell-induced, positive selection occurs only with TCRs that exhibit relatively high avidity interactions with selecting ligands in the thymus is discussed.
SurfWave: an object-oriented class library for wavelet analysis (2002)

This paper addresses the design and development of a software environment for experimenting with filter banks, wavelets, and wavelet packets. An object-oriented class library, called SurfWave, is developed that provides a straightforward interface for experimenting and applying wavelet theory. SurfWave uses the power of C++ for efficiency and ease-of-use by isolating the user from distracting software and hardware peculiarities. It can be easily modified to provide new functionality, i.e., support for new cost functions, optimization algorithms, filter bank topologies, etc. SurfWave is available on several platforms (Unix, PC/Windows, Macintosh) and languages (C++, Matlab, CPX), presenting a uniform "point-of-departure" to the widest cross-section of wavelet enthusiasts.
Comparison of Visual and Ultraviolet Light Inspection Versus DNA/Protein Biomarkers to Assess Product Adherence With Vaginal Microbicide Applicators (2014)

Impaired Endothelial Function in Ovariectomised Rats: Effects of Tempol (2012)

Menopause causes endothelial dysfunction. We investigated the hypothesis that reactive oxygen species (ROS) mediate the adverse effects of ovariectomy (OVX) on microvessels. Mesenteric arterioles (MAs) were isolated from rats 4–6 weeks after sham‐operation (S) or OVX alone, S or OVX rats were given vehicle or tempol (2 mmol · l −1 ) throughout (n=6/group) to measure endothelium derived relaxation factor (EDRF) and endothelium dependent contracting factor (EDCF) using a wire myograph. NO and ROS were quantitated by DAF‐FM and tempo‐9AC‐fluorescence using RatioMasterTM. OVX rats had increased mean blood pressure (MBP) (114±7 vs 88±6.5 mmHg, P&lt;0.05). Their MAs had increased medium:lumen ratio (4.44±0.38 vs 1.54±0.29, P&lt;0.01) and EDRF (20±4 vs 41±4%, P&lt;0.001) and decreased NO activity (0.37±0.1 vs 0.7±0.1 Units, P&lt;0.01). However, OVX rats developed a new EDCF response (20±6 vs 5±5%, P&lt;0.05) accompanied by increased ROS activity (0.22±0.09 vs 0.10±0.01 units; P&lt;0.01). Tempol prevented significant changes in BP, vascular remodeling, EDRF and NO activity, and prevented any EDCF or ROS responses in OVX rats. In conclusion, OVX causes hypertension and microvascular remodeling and redirects endothelial responses from relaxation to contraction accompanied by reduced vascular NO and enhanced ROS. All of these effects are dependent on ROS and could, therefore, be targeted with effective antioxidant therapy.

Designing a Novel Polymer Electrolyte for Improving the Electrode/Electrolyte Interface in Flexible All-Solid-State Electrical Double-Layer Capacitors (2018)

A novel copolymer, polyurethane-poly(acrylic acid) (PAA), is successfully synthesized from poly(acrylic acid) (PAA) backbone cross-linked with waterborne polyurethane (WPU). This sticky polymer, which is neutralized with 1 M KOH and then soaked in 1 M KOH (denoted as WPU-PAAK-K), provides an ionic conductivity greater than 10<sup>-2</sup> S cm<sup>-1</sup> and acts as a gel electrolyte perfectly improving the electrode/electrolyte interfaces in a flexible all-solid-state electrical double-layer capacitor (EDLC). The PAA backbone chains in the copolymer increase the amount of carboxyl groups and promote the segmental motion. The carboxyl groups enhance the water-uptake capacity, which facilitates the ion transport and promotes the ionic conductivity. The cross-linked agent, WPU chains, effectively maintains the rich water content and provides mechanical stickiness to bind two electrodes together. An acid-treated carbon paper (denoted as ACP) combining with such a gel polymer electrolyte demonstrates excellent capacitive behavior with a high areal capacitance of 211.6 mF cm<sup>-2</sup> at 10 mV s<sup>-1</sup>. A full cell consisting of ACP/WPU-PAAK-K/ACP displays a low equivalent series resistance of 0.44 Ω from the electrochemical impedance spectroscopic results. An all-solid-state ACP/WPU-PAAK-K/ACP EDLC provides an areal specific capacitance of 94.6 mF cm<sup>-2</sup> at 1 mA cm<sup>-2</sup>. This device under 180° bending shows a capacitance retention over 90%, revealing its remarkable flexibility.
