Detailed Structural, Spectroscopic, and Electrochemical Trends of Halido Mono- and Bis(NHC) Complexes of Au(I) and Au(III) (2013)

A complete series of ten Au(I) and Au(III) NHC complexes of the general formulas [AuIX(iPr2-bimy)] (1–3, X = Cl, Br, and I), [AuI(iPr2-bimy)2]BF4 (4), [AuIIIX3(iPr2-bimy)] (5–7, X = Cl, Br, and I) and trans-[AuIIIX2(iPr2-bimy)]BF4 (8–10, X = Cl, Br, and I) bearing the iPr2-bimy ligand, and all three common halido ligands have been synthesized and fully characterized. Detailed trends in their NMR and UV–Vis spectroscopic properties have been studied, and their electrochemical behavior have been probed by cyclic voltammetry. The solid state molecular structures of all new complexes determined by single crystal X-ray diffraction are also described.
Global Gender Research (2013)

Readers of Global Gender Research will learn to compare and contrast feminist concerns globally, gain familiarity with the breadth of gender research, and understand the national contexts that produced it. This volume provides an in-depth comparative picture of the current state of feminist sociological gender and women's studies research in four regions of the world—Africa, Asia, Latin America/the Caribbean, and Europe—as represented by many countries. The introductory essay to each region explains how social science research on women and/or gender issues has been shaped by economics, politics, and culture, and by trends that are simultaneously local, regional, and global. It familiarizes readers with the wide range of salient issues, research methods, writing styles, and leading authors from around the globe. Each regional section includes several chapters on gender research in specific countries that represent the region's diversity and cover the major theoretical and empirical trends that have emerged over time, as well as the relationship of key research questions to feminist activism and women’s or gender studies. Next, the editors illustrate this new wave of gender scholarship with translated/reprinted samples of research articles from additional countries in the region, that cover a wide range of important global topics—such as work, sexuality, masculinities, childcare and family issues, religion, violence, law and gender policies. Finally, this volume provides scholars with extensive bibliographies and a listing of web sites for women’s and gender research centers in 85 countries.

Cane-sugar feeding in Culex pipiens fatigans. (1967)

The relatively poor results that have been obtained in controlling or eradicating Culex pipiens fatigans, the urban vector of Wuchereria bancrofti, have made it necessary to obtain as much information as possible about its biology. In this paper the unexpected finding of the influence of cane sugar in delaying oviposition in the gravid female is reported. This is an important finding for those who are investigating the biology of this mosquito in the laboratory and who make use of the age-old practice of keeping adult mosquitos alive by feeding them cane sugar. It is also reported that under certain conditions extensive cane-sugar feeding takes place in nature and it seems possible that this habit may have unsuspected repercussions on behaviour and physiology beyond the confines of the laboratory. One possible development would be the isolation of the attractant present in unrefined sugars and its use in traps in order to assess mosquito populations in the field.
Development of a Software-Defined Radar (2017)

Abstract : In wartime environments, radio frequency interference (RFI) is created by communication devices, jammers, and other electronic sources. The RFI spectrum is assumed to be nonstationary over time, which creates potential to disrupt desired radar operation. The cognitive radar system discussed herein mitigates the effects of RFI by sensing and adapting the transmitted waveform to the widest available (unoccupied) instantaneous bandwidth in real time. Consequently, the radar range resolution and target detection are ameliorated. Results of a prototype cognitive radar implemented on an Ettus X310 software-defined radio are presented.
QSulf1 remodels the 6-O sulfation states of cell surface heparan sulfate proteoglycans to promote Wnt signaling (2003)

The 6-O sulfation states of cell surface heparan sulfate proteoglycans (HSPGs) are dynamically regulated to control the growth and specification of embryonic progenitor lineages. However, mechanisms for regulation of HSPG sulfation have been unknown. Here, we report on the biochemical and Wnt signaling activities of QSulf1, a novel cell surface sulfatase. Biochemical studies establish that QSulf1 is a heparan sulfate (HS) 6-O endosulfatase with preference, in particular, toward trisulfated IdoA2S-GlcNS6S disaccharide units within HS chains. In cells, QSulf1 can function cell autonomously to remodel the sulfation of cell surface HS and promote Wnt signaling when localized either on the cell surface or in the Golgi apparatus. QSulf1 6-O desulfation reduces XWnt binding to heparin and HS chains of Glypican1, whereas heparin binds with high affinity to XWnt8 and inhibits Wnt signaling. CHO cells mutant for HS biosynthesis are defective in Wnt-dependent Frizzled receptor activation, establishing that HS is required for Frizzled receptor function. Together, these findings suggest a two-state "catch or present" model for QSulf1 regulation of Wnt signaling in which QSulf1 removes 6-O sulfates from HS chains to promote the formation of low affinity HS-Wnt complexes that can functionally interact with Frizzled receptors to initiate Wnt signal transduction.
The propagation of a Gaussian pulse in sea water and its applicaiton to remote sensing (1993)

The propagation of a single Gaussian pulse in sea water and of a Gaussian pulse as an envelope for a low-frequency burst are analyzed and their anomalous behavior determined. The use of such a pulse to locate a metal cylinder submerged in the sea is studied quantitatively for two pulse widths. It is concluded that detection of the cylinder by means of its backscattered field should be possible.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Efficient frequency offset resolution for OFDM systems based on ML principle (2004)

The main disadvantage of OFDM systems is its sensitivity to carrier frequency offset (CFO) and timing offset. In this paper, an efficient method for estimating CFO is developed based on maximum likelihood principle, of which emphasis on the CFO ambiguity resolution. In this method, only one training symbol is required and the range of the CFO that can be handled is the overall transmission spectrum. Differential coding in frequency-domain is performed to estimate the integral part of CFO (IFO). When frequency-selective channel is present, prior information of the statistic of the channel frequency response is used to eliminate its effect on estimation performance. Computer simulations are performed to show the superiority to the method available.

Methylation of histone H4 at aspartate 24 by Protein L-isoaspartate O-methyltransferase (PCMT1) links histone modifications with protein homeostasis (2014)

Histone modifications play crucial roles in modulating chromatin function and transcriptional activity. Due to their long half-life, histones can, in addition to post-translational modifications, also accumulate spontaneous chemical alterations, which can affect their functionality and require either protein repair or degradation. One of the major sources of such protein damage or ageing is the conversion of aspartate into isoaspartate residues that can then be methylated. Here, we characterize a novel histone modification, the methylation of histone H4 at aspartate 24 (H4D24me). We generated H4D24me specific antibodies and showed that H4D24me is ubiquitously present in different mouse and human cells. Our in vitro and in vivo data identified PCMT1 (Protein L-isoaspartate O-methyltransferase), an enzyme involved in protein repair, as a novel H4D24 specific histone methyltransferase. Furthermore, we demonstrated that VprBP (HIV-1 viral protein R (Vpr)-binding protein), a chromo domain-containing protein, specifically recognizes H4D24me potentially implicating H4D24me in H4 degradation. Thus, this work links for the first time a histone modification with histone protein aging and histone homeostasis, suggesting novel functions for histone modifications beyond transcriptional regulation.
Cathode processes and materials for solid oxide fuel cells with proton conductors as electrolytes (2010)

This article provides a brief review of the cathode reaction mechanisms in proton-conducting solid oxide fuel cells (H-SOFCs) and a comparative analysis of electrochemical performance and the ionic and electronic transport in cathode materials. The transfer of protons from electrolyte to triple phase boundaries (TPBs) and the diffusion of O−ad from catalytic sites to TPBs are proposed to be the rate-limiting steps for H-SOFCs, of which the latter is more related to the cathode components, microstructure, conducting species and electrical conductivity. The experimental and theoretical analyses also suggest that cathode materials with electron and proton conductivity present smaller polarisation resistances due to the ability of protons to transfer from the electrolyte into the bulk, which extends the reaction areas for protons and oxygen species to the entire gas/cathode surface.

The impact of peripheral arterial disease on health-related quality of life in the Peripheral Arterial Disease Awareness, Risk, and Treatment: New Resources for Survival (PARTNERS) Program (2008)

This study tested the hypothesis that patients with PAD have impaired health-related quality of life (HRQoL) to a degree similar to that of patients with other types of cardiovascular disease (other-CVD), and also evaluated the clinical features of PAD associated with impaired HRQoL. This was a cross-sectional study in 350 primary care practice sites nationwide with 6,499 participants. The reference group had no clinical or hemodynamic evidence of PAD or other-CVD; the PAD group had an ankle-brachial index < 0.90 or a prior history of PAD; the other-CVD group had a clinical history of cardiac or cerebral vascular disease (but no PAD), and the combined PAD-other-CVD group included both diagnoses. Individuals were assessed using four HRQoL questionnaires including the Walking Impairment Questionnaire (WIQ), Medical Outcomes Study SF-36 (SF-36), Cantril Ladder of Life and the PAD Quality of Life questionnaire. PAD patients had lower WIQ distance scores than the other-CVD group. Both the PAD and other-CVD groups had significantly lower SF-36 Physical Function scores compared with the reference group. The WIQ revealed that PAD patients were more limited by calf pain, whereas other-CVD patients were more limited by chest pain, shortness of breath and palpitations. In conclusion, in this nationwide study, one of the first to directly compare the HRQoL burden of CVD with that of PAD, the evaluation of PAD in office practice revealed a HRQoL burden as great in magnitude as in patients with other forms of CVD.
Compared Protective Effect of Nasal Immunoprophylaxis Using a New Human Monoclonal IgM Antibody, Human Polyclonal Antibodies, F(ab′)2, Amantadine, and Zanamivir for Prophylaxis of Influenza A Virus Pneumonia in Mice (2003)

This study evaluated the effectiveness of five human monoclonal antibodies in comparison with human polyclonal antibodies, F(ab')2, amantadine, and zanamivir in a mouse model of lethal influenza A virus infection. A single intranasal administration of antibodies was done for immunoprophylaxis. Zanamivir was administered intranasally and amantadine was administered orally. Mice were fully protected by a single dose of 30 mg/kg intravenous Ig administered at least 3 days before challenge. This treatment was equivalent to zanamivir. F(ab')2 were less effective (p < 0.001). One of the monoclonal antibodies tested was less efficient than both zanamivir (p < 0.001) and intravenous Ig (p < 0.001) but similar to amantadine.
A parallel multigrid Poisson solver for fluids simulation on large grids (2010)

We present a highly efficient numerical solver for the Poisson equation on irregular voxelized domains supporting an arbitrary mix of Neumann and Dirichlet boundary conditions. Our approach employs a multigrid cycle as a preconditioner for the conjugate gradient method, which enables the use of a lightweight, purely geometric multigrid scheme while drastically improving convergence and robustness on irregular domains. Our method is designed for parallel execution on shared-memory platforms and poses modest requirements in terms of bandwidth and memory footprint. Our solver will accommodate as many as 7682 x 1152 voxels with a memory footprint less than 16 GB, while a full smoke simulation at this resolution fits in 32 GB of RAM. Our preconditioned conjugate gradient solver typically reduces the residual by one order of magnitude every 2 iterations, while each PCG iteration requires approximately 6.1 sec on a 16-core SMP at 7683 resolution. We demonstrate the efficacy of our method on animations of smoke flow past solid objects and free surface water animations using Poisson pressure projection at unprecedented resolutions.

Flow Modeling and Rendering to Support 3D River Shipping Based on Cross-Sectional Observation Data (2020)

The flow in meandering rivers is characterized by rapid changes in flow velocity and water level, especially in flooded environments. Accurate cross-sectional observation data enable continuous monitoring of flow conditions, which is important for river navigation. In this paper, cross-sectional data based flow modeling and rendering methods are studied to build an interactive hybrid flow environment for three-dimensional river shipping. First, the sparse cross-sectional data are extrapolated and interpolated to provide dense sampling points. Then, the data are visualized separately by dynamic texture mapping, particle tracking, streamline rendering, and contour surface rendering. Finally, the rendering models are integrated with ship animation to build a comprehensive hybrid river navigation scenario. The proposed methods are tested by visualizing measured cross-sectional data in the Yangtze River using an open-source software, called World Wind. The experimental results demonstrate that the hybrid flow rendering achieves comprehensive visual effect and the rendering frame rate is greater than 30. The interactive hybrid flow visualization is beneficial to support river shipping analysis.
A 63 GHz single-feed low-profile Fabry-P&#x00E9;rot cavity antenna using a thick metallic FSS (2013)

A simple solution for a 63 GHz planar single-feed Fabry-Pérot cavity (FPC) antenna covered by a thick metallic frequency selective surface (FFS) is proposed. The antenna is fed through a planar feed consisting of a coplanar-waveguide-fed slot on the ground plane of the cavity. The FSS is made of periodic circular slots in a thick Brass plate. Moreover, the sides of the metallic FSS are terminated with vertical metallic walls leading to a self-supported low-profile FPC filled with air. Good agreement is observed between measured and simulated results.
Design of a Time Synchronization System Based on GPS and IEEE 1588 for Transmission Substations (2016)

Accurate timing is often required for the intelligent electronic devices (IEDs) used in transmission substations. A common method of achieving this is direct connection of a device to a local global positioning system (GPS) receiver and the use of its one-pulse-per-second synchronizing signal and the IRIG-B coded message. However, concerns about GPS reliability are encouraging the use of timing systems less dependent on the direct use of local GPS receivers. The IEEE 1588 protocol is a network-based time synchronization technique designed to coexist with IEC 61850 applications and deliver sub microsecond timing accuracy. Many utilities are now considering the adoption of IEEE 1588, but they need confidence in the reliability of this technology before it can be rolled out to real substations. Hence, comprehensive tests were undertaken on an IEEE 1588 timing system, to help gain insight into the limitations of the system. This paper presents a procedure to assess the performance of a timing system based on distributed GPS receivers and one based on a mixture of GPS receivers and IEEE 1588 devices. Test results indicate whichever system is selected, high quality devices and systems, with appropriate installation and engineering, are essential to satisfy the stringent ±1 μs accuracy requirements needed by critical IED applications.
Four-wave mixing in an artificial Kerr medium (1981)

Degenerate four-wave mixing experiments have been performed using a liquid suspension of 0.234-microm-diameter latex spheres as the nonlinear medium. The measured effective optical Kerr coefficient, n(2), is 3.6 x 10(-3) (MW/cm(2))(-1). This is ~10(5)x the value for CS(2). Measured grating reflectivity, formation, and decay times are in reasonable agreement with a simple model assuming Rayleigh scattering and Brownian diffusion.
Pyrosequencing Reveals the Influence of Organic and Conventional Farming Systems on Bacterial Communities (2012)

It has been debated how different farming systems influence the composition of soil bacterial communities, which are crucial for maintaining soil health. In this research, we applied high-throughput pyrosequencing of V1 to V3 regions of bacterial 16S rRNA genes to gain further insight into how organic and conventional farming systems and crop rotation influence bulk soil bacterial communities. A 2×2 factorial experiment consisted of two agriculture management systems (organic versus conventional) and two crop rotations (flax-oat-fababean-wheat versus flax-alfalfa-alfalfa-wheat) was conducted at the Glenlea Long-Term Crop Rotation and Management Station, which is Canada's oldest organic-conventional management study field. Results revealed that there is a significant difference in the composition of bacterial genera between organic and conventional management systems but crop rotation was not a discriminator factor. Organic farming was associated with higher relative abundance of Proteobacteria, while Actinobacteria and Chloroflexi were more abundant in conventional farming. The dominant genera including Blastococcus, Microlunatus, Pseudonocardia, Solirubrobacter, Brevundimonas, Pseudomonas, and Stenotrophomonas exhibited significant variation between the organic and conventional farming systems. The relative abundance of bacterial communities at the phylum and class level was correlated to soil pH rather than other edaphic properties. In addition, it was found that Proteobacteria and Actinobacteria were more sensitive to pH variation.
Selective Pressure of Antibiotic Pollution on Bacteria of Importance to Public Health (2012)

Measured environmental concentrations of antibiotics, as well as concentrations representing environmental risk assessment action limits, are high enough to exert a selective pressure on clinically relevant bacteria that may lead to an increase in the prevalence of resistance.
YBaCuO-deposition on metal tape substrates (2001)

Ni and Ni-alloy substrates were used for the deposition of YBa/sub 2/Cu/sub 3/O/sub 7/-tape conductors. Cube texture of the metallic substrates was achieved by cold rolling and annealing at temperatures >850/spl deg/C resulting in well aligned cube texture. Tape samples up to 20 cm in length were heated up to the deposition temperature of 670/spl deg/C in a reducing Ar/H-gas ambient to remove oxides from the Ni substrate surface. Subsequently, CeO/sub 2/-based buffer layers were deposited by vacuum evaporation. YBa/sub 2/Cu/sub 3/O/sub 7/-films were grown on this tape by thermal co-evaporation and intermittent oxidation in a turntable substrate holder. We obtained transition temperatures up to 87 K and critical current densities at 77 K in excess of 1 MA/cm/sup 2/. Critical current characterization in external magnetic fields revealed an excellent power of resistance. Up to 10 T the critical current dropped only by a factor of two and leveled off at higher fields yielding 45 % of its zero field value even at 15 T.
