Correlation between Single Nucleotide Polymorphisms in Endothelial Constitutive Nitric Oxide Synthase Gene and Type 2 Diabetes Mellitus (2010)

Objective To investigate the correlation between single nucleotide polymorphism (SNP) of endothelial constitutive nitric oxide synthase (ecNOS) and type 2 diabetes mellitus (T2DM).Methods DNA samples of peripheral blood white cells were extracted from 210 patients with T2DM and 196 healthy individuals.Tag SNPs of rs7830 and rs3918188 mutations in the ecNOS gene were analyzed with allele-specific fluorogenic oligonucleotide probes in an assay combining the polymerase chain reaction (PCR) and hybridization.Results The CC genotype and C alleles frequencies of rs7830 of T2DM group were obviously lower than those of control group (P0.05).The frequencies of the genotypes and alleles of rs3918188 were not significantly different between two groups (P0.05).The haplotypes of rs7830 and rs3918188 were constructed and the frequencies of haplotypes were not significantly different between two groups (P0.05).Conclusion Rs7830 mutations in the ecNOS gene might be a genetic risk factor for T2DM.
AlGaN-GaN UV light-emitting diodes grown on SiC by metal-organic chemical vapor deposition (2002)

We report the study of the electrical and optical characteristics of AlGaN-GaN quantum-well (QW) ultraviolet light-emitting diodes grown on SiC by metal-organic chemical vapor deposition. These devices exhibit room-temperature electroluminescence emission peaked at /spl lambda/ = 363 nm with a narrow linewidth of /spl Delta//spl lambda/ = 9 nm under high-current-density dc injection. We have also applied a Mg-doped AlGaN-GaN superlattice structure as a p-cladding layer and vertical-geometry hole conduction improvement has been verified. A comparative study of the performance of light-emitting devices with single-QW and multiple-QW structures indicates that the single-QW structure is preferred.
A virtual environment for simulating manufacturing operations in 3D (2001)

This paper presents a method for simulating basic manufacturing operations (unload, load, process, move, and store) in a 3D virtual environment. The virtual environment provides a framework for representing a facility layout in 3D, which encapsulates the static and the dynamic behavior of the manufacturing system. The 3D manufacturing objects in the facility are mapped with the nodes in the framework. The framework, a modified scenegraph structure, is a tree structure, which can be manipulated by updating the parent-child relationships and the transformation matrix to simulate the basic manufacturing operations. The method can be easily extended to represent more specific manufacturing operations.
A new approach to target recognition for LADAR data (2001)

We discuss target detection in LADAR intensity images. Thirteen features, eleven of which come from an asymmetric co-occurrence matrix, are extracted from region-of-interest windows in each image. Two methods of feature selection are applied to the extracted vectors. Random selection leads to a pair of selected features for a nearest-neighbor rule (1-nn) detector. Extended backpropagation leads to six selected features using a modified multilayered perceptron (MLP) network. The 1-nn detector achieves a test-error rate of about 16% at a false-alarm rate of 8%. The MLP has a test-error rate of about 12% with a false-alarm rate of 6%.
The application of laser Doppler velocimetry to trailing vortex definition and alleviation (1973)

A laser Doppler velocimeter whose focal volume can be rapidly traversed through a flowfield has been used to overcome the problem introduced by excursions of the central vortex filament within a wind tunnel test section. The basic concepts of operation of the instrument are reviewed and data are presented which accurately define the trailing vortex from a square-tipped rectangular wing. Measured axial and tangential velocity distributions are given, both with and without a vortex dissipator panel installed at the wing tip. From the experimental data, circulation and vorticity distributions are obtained and the effect of turbulence injection into the vortex structure is discussed.

Early Identification of Fertility in Hens’ Eggs (1938)

IT IS common practice among hatchery-men to wait until eggs have been incubated 14 to 18 days before removing the infertiles. Although infertile eggs are easily detected at this age, by simply passing the tray over a group of lights, nevertheless much incubator space is occupied by them which could be profitably used if the infertile eggs were removed earlier. Still other benefits would be obtained if the two classes of eggs could be distinguished at an early hour of incubation. For example, a poultryman could quickly check the fertility of the eggs from his flock and a scientist could conduct certain experiments using only fertile eggs if he so desired. With this in mind, a series of experiments was conducted to determine the earliest and most practical time when infertile white and brown shelled eggs could be removed from the incubator. Preliminary investigations on this project were begun the . . .
Signal Deformations On Nominally Healthy GPS Satellites (2004)

This paper describes the collection and analysis of real data from twenty-four current, nominally healthy GPS satellites in the context of the ICAO second-order step (2OS) fault model. A simple but novel method is presented for averaging multiple C/A code epochs together, using Doppler prediction to achieve essentially open-loop synchronous sampling of the code waveform. This yields a clean picture of the C/A code edge transitions. Two different methods are then used to estimate the digital failure mode parameter, that characterizes each observed satellite within the context of the 2OS model. The results of this analysis are grouped by satellite block and, separately, by the type of frequency standard in operation at the time of measurement. Finally, the potential implications of these measurements on integrity and continuity are discussed.
Electrocardiogram Monitoring (1990)

ecent years have brought a dramatic increase in the number of local procedures .performed in the operating room. Monitoring patients receiving local anesthesia without the presence of an anesthesiologist is now a vital part of the perioperative nurse's role. The AORN recommended practices concerning monitoring patients under local anesthesia include monitoring heart rate and rhythm to detect cardiovascular responses to local anesthesia.' This monitoring is critical because local anesthetic agents can cause a variety of negative effects, including cardiovascular and respiratory depression.
Homosexuality and the Validity of Marriage - The Developing Jurisprudence (1976)

This article will explore the state of the question regard-ing the evolving jurisprudence in such cases. The author presup-poses his readers &apos; familiarity with the medical literature and will concentrate on the decisions of Church courts on the marital ca-pacity of homosexuals.)

Industry Effects and Appropriability Measures in the Stock Markets Valuation of R&D and Patents (1987)

This paper examines the stock market's valuation of a firm's innovative activity. We estimate the market's relative valuation of firms' tangible and intangible assets, focusing on knowledge capital in the form of accumulated stocks of R&D and patents. We tried to improve upon our estimates of the stock market's valuation of knowledge capital embodied in such stocks by bringing in measures of the appropriability environment facing a firm from the Yale Survey on Industrial Research and Development. The responses to Survey questions about the effectiveness of patents as a mechanism for protecting the returns from innovation turn out to be of some use: there is evidence of an interaction between industry level measures of the effectiveness of patents and the market's valuation of a firm's past R&D and patenting performance, as well as its current R&D moves. We find no evidence, however, that other appropriability mechanisms differ enough across industries to leave measurable traces in our data. The structure of the Yale Survey makes it possible to estimate the sampling error in the appropriability measures derived from it. This information was used by us in an errors-in-variables context, but with little success. In the absence of R&D variables, our estimates imply that a two standard deviation increase in our index of patent effectiveness would raise the value of a patent held by our average firm from $0.4 million to $1.0 million. When R&D variables are introduced into the equations, the patents variables become insignificant - R&D expenditures are a better measure of input to the innovative function of firms than patents are of its output - but we estimate that the same experiment would induce changes in q of between 10 and 27 percent for the average firm, approximately doubling the market's valuation of this kind of capital.
The HIV-1 gp120 envelope protein has the intrinsic capacity to stimulate monokine secretion (1991)

Results and conclusions concerning the ability of HIV glycoprotein (gp) 120 to stimulate monokine secretion have been equivocal, based on observations using natural gp120 derived from infected human cells and a Chinese hamster ovary (CHO) cell-derived recombinant fusion protein. Current studies were designed to determine whether differences in recombinant gp120 proteins could result in failure to trigger monokine production. We found that natural gp120 could stimulate monocytes to release TNF-alpha, IL-1 beta, IL-6, and granulocyte-macrophage-CSF, and this effect could be blocked with soluble CD4. Full-length rgp120 either expressed from an adenovirus vector and purified from infected human cells, or derived from CHO cells, could function similarly. In contrast, full-length recombinant envelope protein expressed in a baculovirus system and a CHO cell-derived recombinant fusion protein tested previously, consistently failed to stimulate monokine production. The stimulatory capacity of both natural and full-length CHO cell-derived gp120 was eliminated by heating at 100 degrees C, and could be blocked with excess CHO cell-derived gp120 fusion protein. Inasmuch as the baculovirus-expressed gp120 and the CHO cell-derived recombinant fusion protein can bind to CD4, these results suggest that HIV gp120 binding to CD4 on the monocyte surface may of itself be insufficient for stimulation of monokine secretion. Therefore, primary protein structure, as well as posttranslational protein modifications, may determine this activity.
Experimental feasibility of spectral photon-counting computed tomography with two contrast agents for the detection of endoleaks following endovascular aortic repair (2018)

• SPCCT might enable advanced endoleak detection. • Material maps derived from SPCCT can differentiate iodine, gadolinium and calcium. • SPCCT may potentially reduce radiation burden for EVAR patients under post-interventional surveillance.
Electrical detection of ferromagnetic resonance in single layers of permalloy: Evidence of magnonic charge pumping (2015)

The generation of a DC voltage in single layers of permalloy (${\mathrm{Ni}}_{81}{\mathrm{Fe}}_{19}$) when the magnetization is undergoing ferromagnetic resonance is investigated in a series of samples with thickness varying from 4.0 to 150 nm. By sweeping the external field at a fixed microwave frequency, we measure a DC voltage at the ends of the layer as a function of the in-plane angle for each sample. The asymmetric voltage signal generated at the resonance field is a superposition of symmetric Lorentzian and antisymmetric Lorentzian derivative line shapes. The in-plane dependence of both symmetric and antisymmetric signals cannot be explained as due to spin rectification (SRE) only. The results are well explained by a model that takes into account in addition to the SRE the contribution of the recent discovered effect of magnonic charge pumping that converts magnetization dynamics into charge current by means of the spin orbit coupling.
Tendon arrangement and muscle force requirements for human-like force capabilities in a robotic finger (2003)

Human motion can provide a rich source of examples for use in robot grasping and manipulation. Adapting human examples to a robot manipulator is a difficult problem, however, in part due to differences between human and robot hands. Even hands that are anthropomorphic in external design may differ dramatically from the human hand in ability to grasp and manipulate objects due to internal design differences. For example, force transmission mechanisms in robot fingers are generally symmetric about flexion/extension axes, but in human fingers they are focused toward flexion. This paper describes how a tendon driven robot finger can be optimized for force transmission capability equivalent to the human index finger. We show that two distinct tendon arrangements that are similar to those that have been used in robot hands can achieve the same range of forces as the human finger with minimal additional cost in total muscle force requirements.
Effect of bradykinin on airway function. (1992)

Bradykinin (BK) has several effects on airway function which may be relevant in obstructive airways disease. These effects are mediated via B2-receptors. BK is a potent bronchoconstrictor in animals and humans in vivo. Bradykinin contracts airway smooth muscle, is a potent bronchial vasodilator, increases microvascular leakage, stimulates epithelial cells to release bronchodilators and stimulates mucus secretion. Perhaps its most important action is the activation of sensory nerves in airways, leading to reflex bronchoconstriction, coughing and neurogenic inflammation through the release of neuropeptides from sensory nerves.
The von Willebrand Factor A3 Domain Does Not Contain a Metal Ion-dependent Adhesion Site Motif (1997)

von Willebrand factor (vWF) is a multimeric plasma protein that mediates platelet adhesion to exposed subendothelium at sites of vascular injury. The A3 domain of vWF (vWF-A3) forms the principal binding site for collagens type I and III. We report here the crystal structure of the vWF-A3 domain at 2.2-A resolution. As expected, the structure is similar to the integrin I domain but with several novel features. Sequence alignments had suggested that the domain contained an integrin metal ion-dependent adhesion site (MIDAS) motif, but the crystal structure shows that the motif is modified and that no metal ion is bound. We have introduced mutations into the vestigial MIDAS motif and report that, unlike the I domain of integrin alpha2beta1, vWF-A3 continues to bind collagen after disruption of the motif. We conclude that collagen recognition by vWF-A3 occurs by a mechanism different from that of the integrin alpha2beta1.

Interkingdom Transfer of the Acne-Causing Agent, Propionibacterium acnes, from Human to Grapevine (2014)

Here, we report the surprising and, to our knowledge, unique example of horizontal interkingdom transfer of a human opportunistic pathogen (Propionibacterium acnes) to a crop plant (the domesticated grapevine Vitis vinifera L.). Humans, like most organisms, have established a long-lasting cohabitation with a variety of microbes, including pathogens and gut-associated bacteria. Studies which have investigated the dynamics of such associations revealed numerous cases of bacterial host switches from domestic animals to humans. Much less is, however, known about the exchange of microbial symbionts between humans and plants. Fluorescent in situ hybridization localized P. acnes in the bark, in xylem fibers, and, more interestingly, inside pith tissues. Phylogenetic and population genetic analyses suggest that the establishment of the grapevine-associated P. acnes as obligate endophyte is compatible with a recent transfer event, likely during the Neolithic, when grapevine was domesticated.

This information are obtained from 31 companies to which the author sent a questionnaire. SAW propagation characteristics such as Rayleigh wave and leaky wave are also briefly summarized.
A Spectroscopic Study of Alpha-Ray-Induced Luminescence in Gases: Part I (1966)

In radiation chemistry, an understanding of the primary processes induced by ionizing radiation and the kinetics of the ions, atoms, and excited species is of paramount importance. From this basic information, chemical systems under ionizing radiation may be directed to produce desired phenomena. The fixation of nitrogen by means of ionizing radiation is one of the major interests of our group at Rensselaer Polytechnic Institute. In our investigation of the behavior of fission fragments on the nitrogen system, a spectroscopic study of the luminescence was desired. Since it was not possible to study spectroscopically the fission fragment luminescence in a nuclear reactor,2 large polonium a-particle sources were used as the best substitute available.
Mitogenic analysis of murine B-cell heterogeneity. (1978)

The B-cell mitogens lipopolysaccharide (LPS), Nocardia water-soluble mitogen (NWSM), and dextran sulfate (DxS) react with different subpopulations of B lymphocytes. Selective in vitro killing of cells responding to either LPS or NWSM has little effect on the in vitro response to the other mitogen, although the response to DxS is reduced in both cases. If, after selective in vitro killing, cells are injected into irradiated mice for 2-3 wk before measuring their in vitro mitogen responses, the same specificity pattern is seen. Thus, one is dealing with different B-cell subpopulations rather than different stages of maturation of a single population. Treatment with various alloantisera and complement before measuring the mitogen response to LPS and NWSM shows that (a) whereas all LPS response cells carry surface Ig, a subpopulation of NWSM responsive cells does not; (b) both LPS- and NWSM-responsive cells carry I-A antigens but might not I-E or I-J antigens; (c) all LPS-responsive cells carry I-C antigens, whereas approximately 25% of NWSM responsive cells do not: (d) there is a subpopulation of NWSM-responsive cells carrying neither surface Ig nor I-C antigens and resistant to anti-theta treatment.
Accelerating Progress towards Achieving the MDG to Improve Maternal Health : A Collection of Promising Approaches (2005)

One of the Millennium Development Goals (MDG) is to improve maternal health, with the target of reducing maternal mortality by three-quarters between 1990 and 2015. In an effort to accelerate progress towards achieving this MDG, this paper brings together high-quality information on a wide range of promising approaches that aim to improve maternal health outcomes. These global promising approaches, based on field research and practice by experienced organizations working in this arena, can serve as a useful starting point in the process to improve current maternal health programming. This paper will be useful for World Bank staff when assisting client countries in developing their National Poverty Reduction Strategy Papers (PRSPs) and costing health sector plans. Moreover, the paper provides Bank staff with substantive evidence to share with governments on how best to prioritize and implement maternal health programs, and scale up efforts to achieve progress. Although primarily intended for use by Bank staff, we hope this guide will also be useful to governments, other international donor agencies, and nongovernmental organizations (NGOs), who are interested in improving maternal health, and minimizing the disparities that currently exist between industrialized and developing countries.
Self-Digitization of Samples into a High-Density Microfluidic Bottom-Well Array (2013)

This paper describes a sample digitization method that generates tens of thousands of nanoliter-sized droplets in a high-density array in a matter of minutes. We show that the sample digitization depends on both the geometric design of the microfluidic device and the viscoelastic forces between the aqueous sample and a continuous oil phase. Our design avoids sample loss: Samples are split into tens of thousands of discrete volumes with close to 100% efficiency without the need for any expensive valving or pumping systems. We envision this technology will have broad applications that require simple sample digitization within minutes, such as digital polymerase chain reactions and single-cell studies.
