This paper presents t~e results o.fa study on the use ofplasma spraying for the fabrication of metallzc glass coatmgs on mzld steel. A commercial, nickel-based alloy powder, Amdry 915, was found to produce sound, amorphous coatings.The hardness, strength and wear coefficient of the coating are related to the crystallzmty of the alloy. It is shown that the properties of the plasma-sprayed coating compare favourably wzth those of a metallic glass ribbon made of the same commercial alloy.
The Perioperative Period is an Underutilized Window of Therapeutic Opportunity in Patients With Colorectal Cancer (2009)

Because surgery remains the appropriate and necessary means of treatment for most CRC patients, new adjuvant therapeutic strategies that prevent tumor recurrence after surgery need to be explored since the perioperative therapeutic window of opportunity offers promising means of improving patient outcome but is unfortunately underutilized.
Aberrant temporal growth pattern and morphology of root and shoot caused by a defective circadian clock in <i>Arabidopsis thaliana</i> (2012)

Circadian clocks synchronized with the environment allow plants to anticipate recurring daily changes and give a fitness advantage. Here, we mapped the dynamic growth phenotype of leaves and roots in two lines of Arabidopsis thaliana with a disrupted circadian clock: the CCA1 over-expressing line (CCA1ox) and the prr9 prr7 prr5 (prr975) mutant. We demonstrate leaf growth defects due to a disrupted circadian clock over a 24 h time scale. Both lines showed enhanced leaf growth compared with the wild-type during the diurnal period, suggesting increased partitioning of photosynthates for leaf growth. Nocturnal leaf growth was reduced and growth inhibition occurred by dawn, which may be explained by ineffective starch degradation in the leaves of the mutants. However, this growth inhibition was not caused by starch exhaustion. Overall, these results are consistent with the notion that the defective clock affects carbon and energy allocation, thereby reducing growth capacity during the night. Furthermore, rosette morphology and size as well as root architecture were strikingly altered by the defective clock control. Separate analysis of the primary root and lateral roots revealed strong suppression of lateral root formation in both CCA1ox and prr975, accompanied by unusual changes in lateral root growth direction under light-dark cycles and increased lateral extension of the root system. We conclude that growth of the whole plant is severely affected by improper clock regulation in A. thaliana, resulting not only in altered timing and capacity for growth but also aberrant development of shoot and root architecture.
Reduced complexity maximum likelihood sequence estimation for multitrack high-density magnetic recording channels (1999)

In this paper we investigate the problem of designing reduced complexity detectors for multitrack high-density magnetic recording systems. The detectors derived in this work operate on superstate sets and carry several survivors for each set. We show that such a reduced state increased survivor approach provides near optimal performance to the maximum likelihood method, namely the Viterbi Algorithm (VA), but operate at a fractional complexity of the VA.

Measurement of brain volume using MRI: software, techniques, choices and prerequisites. (2009)

Magnetic resonance imaging (MRI) permits in vivo quantification of brain compartment volume, and has many applications in cognitive, clinical and comparative neuroscience. There dre numerous approaches for obtaining a brain volume estimate from MRI, and the primary focus of this paper is to provide an overview of the methods available to estimate the volume of three brain structures that are of particular interest in the neurosciences: the cerebral hemispheres, hippocampus and Brocas area. We provide information on choice of computer software, hardware compatibility, required user expertise, the application of manual and automated MR image analysis techniques, and anatomical guidelines, providing the reader with enough information to decide on their approach at the outset of a quantitative MRI study. We advocate the use ofstereology in conjunction with point counting for an unbiased and time efficient estimate of brain compartment volume.
Laser ablated high T(sub c) superconducting thin YBa2Cu3O(7-x) films on substrates suitable for microwave applications (1990)

The development of high temperature superconducting YBa2Cu3O(7-x) thin films on substrates suitable for microwave applications is of great interest for evaluating their applications for space radar, communication, and sensor systems. Thin films of YBa2Cu3O(7-x) were formed on SrTiO3, ZrO2, MgO, and LaAlO3 substrates by laser ablation. The wavelength used was 248 nm from a KrF excimer laser. During deposition the films were heated to 600 C in a flowing oxygen environment, and required no post annealing. The low substrate temperature during deposition with no post annealing gave films which were smooth, which had their c-axis aligned to the substrates, and which had grains ranging from 0.2 to 0.5 microns in size. The films being c-axis aligned gave excellent surface resistance at 35 GHz which was lower than that of copper at 77 K. At present, LaAlO3 substrates with a dielectric constant of 22, appears suitable as a substrate for microwave and electronic applications. The films were characterized by resistance-temperature measurements, scanning electron microscopy, and x ray diffraction. The highest critical transition temperatures (T sub c) are above 89 K for films on SrTiO3 and LaAlO3, above 88 K for ZrO2, and above 86 K for MgO. The critical current density (J sub c) of the films on SrTiO3 is above 2 x 10(exp 6) amperes/sq cm at 77 K. The T(sub c) and J(sub c) are reported as a function of laser power, composition of the substrate, and temperature of the substrate during deposition.
Laplace inversion of low‐resolution NMR relaxometry data using sparse representation methods (2013)

Low-resolution nuclear magnetic resonance (LR-NMR) relaxometry is a powerful tool that can be harnessed for characterizing constituents in complex materials. Conversion of the relaxation signal into a continuous distribution of relaxation components is an ill-posed inverse Laplace transform problem. The most common numerical method implemented today for dealing with this kind of problem is based on <i>L</i><sub>2</sub>-norm regularization. However, sparse representation methods via <i>L</i><sub>1</sub> regularization and convex optimization are a relatively new approach for effective analysis and processing of digital images and signals. In this article, a numerical optimization method for analyzing LR-NMR data by including non-negativity constraints and <i>L</i><sub>1</sub> regularization and by applying a convex optimization solver PDCO, a primal-dual interior method for convex objectives, that allows general linear constraints to be treated as linear operators is presented. The integrated approach includes validation of analyses by simulations, testing repeatability of experiments, and validation of the model and its statistical assumptions. The proposed method provides better resolved and more accurate solutions when compared with those suggested by existing tools. © 2013 Wiley Periodicals, Inc.

A prototype receiver for medium temperature conversion of solar radiation to heat (2011)

In this article, a solar receiver prototype (marked as P2CC, parabolic-and-circular collector) is described for medium temperature conversion of solar radiation in heat. The investigated concentrator has a tubular receiver and two identical reflectors, one from each side of the tubular receiver. The tubular receiver is a concentric tube consisting of a metal tube (absorber) inside the glass tube. Each reflector curve is defined using three curves where one curve is parabola and two curves are circular arcs. The demonstrated prototype has the reception angle of 110° at concentration ratio CR = 1.38, with the significant reception of diffuse radiation. The hydraulic measurements reveal the pressure drop up to 200 Pa. Thermal measurements discover the high efficiency of the P2CC of up to 75 per cent. The prototype application would mean significant savings of electric energy which is now used for preparation of warm water, and in central and long-distance heating systems.
Integrated Anisotropic Velocity Modeling Using Perforation Shots, Passive Seismic and VSP Data (2006)

Economic development of tight gas reservoirs often rely on hydraulic fracturing to stimulate production. Passive microseismic mapping of these hydraulic fractures is a quickly growing technology to map fracture geometry and complexities created during these stimulations. Reliable microseismic locations depend on an accurate velocity model. In this study we examine velocities obtained from Vertical Seismic Profile (VSP) data, perforation shots from an adjacent well, and microseismic data to determine an anisotropic velocity model for improved microseismic hypocentral locations. The observed anisotropy is consistent with an effective media representation of the geological reservoir structure.
Role of interleukin 10 and transforming growth factor beta1 in the angiogenesis and metastasis of human prostate primary tumor lines from orthotopic implants in severe combined immunodeficiency mice. (1999)

Transfection of primary human prostate tumor cells (i.e., HPCA-10a, 10b, 10c, and 10d lines) with the transforming growth factor (TGF)-beta1 gene stimulated anchorage-independent growth and promoted tumor growth, angiogenesis, and metastasis after orthotopic implantation in severe combined immunodeficiency mice. In contrast, interleukin (IL)-10 transfected cells or cells cotransfected with these two genes exhibited reduced growth rates and significantly reduced angiogenesis and metastasis after 8, 12, and 16 weeks. Enzyme-linked immunosandwich assays confirmed that the respective tumors expressed elevated levels of TGF-beta1 and IL-10 in vivo. ELISAs further showed that TGF-beta1 expression induced matrix metalloproteinases-2 (MMP-2) expression, whereas IL-10 down-regulated MMP-2 expression while up regulating TIMP-1 in the transfected cells. Also, tumor factor VIII levels correlated with TGF-beta1 and MMP-2 expression and inversely with IL-10 and TIMP-1 levels. More importantly, mouse survival was zero after 4-6 months in mice bearing TGF-beta1- and MMP-2-expressing tumors and increased significantly in mice implanted with IL-10- and TIMP-1-expressing tumors (i.e., to >80% survival). Analysis of the metastatic lesions showed that they expressed TGF-beta1 and MMP-2 but barely detectable levels of IL-10 or TIMP-1, suggesting that IL-10 and TIMP-1 might normally block tumor growth, angiogenesis, and metastasis.
Statistical multimodal integration for intelligent HCI (2003)

This paper presents a statistical approach to developing multimodal recognition systems and, in particular, to integrating the posterior probabilities of parallel input signals involved in the multimodal system. We first derive the performance bounds of multimodal recognition probabilities, and identify the primary factors that influence multimodal recognition performance. We then develop a technique, a members-teams-committee (MTC) recognition approach, designed to optimize accurate recognition during the multimodal integration process. We evaluate these methods using Quickset, a speech/gesture multimodal system, and report evaluation results based on an empirical corpus collected with Quickset. From an architectural perspective, the integration technique presented offers enhanced robustness. It also is premised on more realistic assumptions than previous multimodal systems using semantic fusion. From a methodological standpoint, the evaluation techniques that we describe provide a valuable tool for evaluating multimodal systems.
Endoluminal Beta-Radiation Therapy for the Prevention of Coronary Restenosis after Balloon Angioplasty (2001)

Intracoronary beta radiation therapy produces a significant dose-dependent decrease in the rate of restenosis after angioplasty. An 18-Gy dose not only prevents the renarrowing of the lumen typically observed after successful balloon angioplasty, but actually induces luminal enlargement.
Low-cost high power-density electronic ballast for automotive HID lamp (2000)

A low-cost high-efficiency high power-density electronic ballast for 35 W automotive high intensity discharge (HID) is presented along with the results of theoretical computations and experimental tests. The ballast circuits is based on a 100 kHz resonant inverter, a half-wave rectifier and a 400 Hz operated square-wave inverter. The converter operates at zero turn on losses, nearly zero turn off losses, and at a reduced electromagnetic interference level. The ballast circuit is designed to prevent inappropriate operations due to the acoustic resonances. The lamp voltage waveform has limited dv/dt and no DC component contributing to a long operating life of the lamp. A breadboard of the electronic ballast was designed and experimentally tested on a 35 W lamp, for a DC input voltage ranging from 9 V to 16 V. The electronic ballast performs all the features required to turn-on, warm-up and drive at the steady state a 35 W HID lamp and operates at a maximum steady state efficiency /spl eta/=84%,.
Characterization of Receiver Response to Spoofing Attacks (2018)

Test procedures are developed for characterizing the response\nof civil GPS receivers to spoofing attacks. Two response\ncharacteristics are analyzed in detail for four representative\nGPS receivers: (1) the spoofer power advantage\nover the authentic signals required for successful receiver\ncapture, and (2) the aggressiveness with which a spoofer\ncan manipulate the victim receiver’s time and position solution.\nTwo of the tested receivers are commonly used\nin critical infrastructure applications, one in smart power\ngrid regulation and one in telecommunications networks.\nThe implications of the test results for these critical infrastructure\napplications are discussed.

Blog acceptance model: An empirical study on exploring users’ acceptance and continual usage of blogs (2009)

Blogs have permeated into our daily lives at a fast speed,and various kinds of blog spaces have attracted our attention.However,little effort has been made on studying the users’motivation to participate in blog activities.This paper aims to construct a theoretical model about the blog adoption based on technology acceptance model(TAM theory),social capital theory and social exchange theory,and put forward 18 related hypotheses.Then the survey method is adopted to analyze the data from 208 questionnaires using the SPSS and LISREL tools,and to examine the theoretical model and hypotheses.Finally,the paper makes a discussion from five aspects due to the results of data analysis,including individual driving factors,group driving factors,community driving factors,technology acceptance factors and moderating variables.The results show that curiosity/enjoyment,user’s experience,social interaction and social identification will greatly affect users’motivation to accept a blog;meanwhile,perceived ease of use,exchange cost and trust will partially influence users’intention to participate in blog activities.The results also suggest that age and education degrees have significant moderating effects on users’acceptance and updating of blogs.
Longitudinal multi-omics of host–microbe dynamics in prediabetes (2019)

Type 2 diabetes mellitus (T2D) is a growing health problem, but little is known about its early disease stages, its effects on biological processes or the transition to clinical T2D. To understand the earliest stages of T2D better, we obtained samples from 106 healthy individuals and individuals with prediabetes over approximately four years and performed deep profiling of transcriptomes, metabolomes, cytokines, and proteomes, as well as changes in the microbiome. This rich longitudinal data set revealed many insights: first, healthy profiles are distinct among individuals while displaying diverse patterns of intra- and/or inter-personal variability. Second, extensive host and microbial changes occur during respiratory viral infections and immunization, and immunization triggers potentially protective responses that are distinct from responses to respiratory viral infections. Moreover, during respiratory viral infections, insulin-resistant participants respond differently than insulin-sensitive participants. Third, global co-association analyses among the thousands of profiled molecules reveal specific host-microbe interactions that differ between insulin-resistant and insulin-sensitive individuals. Last, we identified early personal molecular signatures in one individual that preceded the onset of T2D, including the inflammation markers interleukin-1 receptor agonist (IL-1RA) and high-sensitivity C-reactive protein (CRP) paired with xenobiotic-induced immune signalling. Our study reveals insights into pathways and responses that differ between glucose-dysregulated and healthy individuals during health and disease and provides an open-access data resource to enable further research into healthy, prediabetic and T2D states.
Myelin‐associated inhibitors of axon regeneration (2003)

Trauma in the adult mammalian central nervous system (CNS) has devastating clinical consequences due to the failure of injured axons to spontaneously regenerate. Over 20 years ago, pioneering work demonstrated that the non-permissive nature of CNS myelin for axon outgrowth contributes to this regenerative failure. Over the past few years, tremendous progress has been made in our understanding of the inhibitory components of CNS myelin, the axonal receptors that respond to these cues, and the intracellular signaling cascades mediating axon outgrowth inhibition. Several approaches designed to antagonize molecular mediators of axon inhibition have been tested in an effort to promote regenerative growth after CNS injury. These studies have validated the role of many candidate proteins in axon outgrowth inhibition; however, other approaches such as the generation of knockout mice for myelin-associated inhibitors have created new questions in the field.
A Region-Based Approach to Digital Image Registration with Subpixel Accuracy (1986)

Automatic registration of images with translational, rotational, and scaling differences is discussed. To register two images from the same scene, first, the images are segmented and closedboundary regions in the images are extracted. Next, centers of gravity of closed-boundary regions are taken as control points and correspondence is established between the control points. Using this correspondence, the original images are then revisited and the segmentation process is refined in such a way that the obtained corresponding regions become optimally similar. This enables determination of centers of gravity of the regions up to subpixel accuracy. Finally, registration parameters are determined by the least squares error criterion.
Structural, Biological, and Evolutionary Relationships of Plant Food Allergens Sensitizing via the Gastrointestinal Tract (2004)

The recently completed genome sequence of the model plant species Arabidopsis has been estimated to encode over 25,000 proteins, which, on the basis of their function, can be classified into structural and metabolic (the vast majority of plant proteins), protective proteins, which defend a plant against invasion by pathogens or feeding by pests, and storage proteins, which proved a nutrient store to support germination in seeds. It is now clear that almost all plant food allergens are either protective or storage proteins. It is also becoming evident that those proteins that trigger the development of an allergic response through the gastrointestinal tract belong primarily to two large protein superfamilies: (1) The cereal prolamin superfamily, comprising three major groups of plant food allergens, the 2S albumins, lipid transfer proteins, and cereal alpha-amylase/trypsin inhibitors, which have related structures, and are stable to thermal processing and proteolysis. They include major allergens from Brazil nut, peanuts, fruits, such as peaches, and cereals, such as rice and wheat; (2) The cupin superfamily, comprising the major globulin storage proteins from a number of plant species. The globulins have been found to be allergens in plant foods, such as peanuts, soya bean, and walnut; (3) The cyteine protease C1 family, comprising the papain-like proteases from microbes, plants, and animals. This family contains two notable allergens that sensitize via the GI tract, namely actinidin from kiwi fruit and the soybean allergen, Gly m Bd 30k/P34. This study describes the properties, structures, and evolutionary relationships of these protein families, the allergens that belong to them, and discusses them in relation to the role protein structure may play in determining protein allergenicity.
