Comparison of Endothelium-Dependent Vasodilation According to the Presence of Diabetes in Coronary Artery Disease (2005)

Background and Objectives：The purpose of this study is to evaluate endothelium dependent vasodilation in the diabetic patients suffering with coronary artery disease (CAD). Subjects and Methods：43 patients who presented with typical chest pain and who underwent coronary angiography were enrolled in this study. They were classified into diabetic patients with CAD (n=13), non-diabetic patients with CAD (n=13), diabetic patients without CAD (n=7), and non-diabetic patients without CAD (n=10), according to the presence of CAD and diabetes mellitus. Endothelium-dependent vasodilation of the brachial artery was measured in all the subjects by performing 7.5 MHz high-resolution ultrasound sonography. Results：The endothelium-dependent vasodilation in the diabetic patients with CAD was 1.30±2.13% and it was 5.72±3.70% in the non-diabetic patients with CAD. There was a significant difference between the two groups (p=0.001). The endothelium-dependent vasodilation in diabetic patients without CAD was 2.28±1.88% and it was 10.70±10.19% in the non-diabetic patients without CAD. There was a significant difference between the two groups (p=0.029). The endothelium-dependent vasodilations in the diabetic group was 2.28±1.88% and it was 10.70±10.19% in the non-diabetic group for all the patients. There was a significant difference between the two groups (p=0.029). There was correlation between the endothelium-dependent vasodilation and the fasting blood sugar. There was negative correlation between the endotheliumdependent vasodilation and the fasting blood sugar (FBS) in the patients with CAD (r=-0.59, p=0.002). However, there was no correlation between the endothelium-dependent vasodilation and the FBS in the patients without CAD (r=-0.327, p=0.201). There was negative correlation between the endothelium-dependent vasodilation and the FBS in all subjects (r=-0.352, p=0.021). Conclusion：The endothelium-dependent vasodilation was decreased in the diabetic patients with CAD as compared to the non-diabetic patients with CAD. There was also was negative correlation between the endothelium-dependent vasodilation and the FBS in the patients with CAD. (Korean Circulation J 2005;35:910-915)
Integration of an IEEE Std. C37.118 compliant PMU into a real-time simulator (2015)

The simulation of Phasor Measurement Units (PMUs) into real-time simulators (RTSs) is typically limited by the complexity of the synchrophasor estimation (SE) algorithm. This is especially true when dealing with distribution network PMUs due to the more demanding accuracy requirement and, for the case of class-P PMUs, for the limited latency. In this respect, if the SE algorithm is too simplistic, the performances of the simulated PMU might not match the specific application needs. On the other hand, when higher precision of the synchrophasors estimations is required, an increased computational complexity of the SE algorithm is obtained and, as a consequence, few devices can be simulated into a RTSs at the same time. The work presented in this paper illustrates the design and the deployment of a C37.118 class-P compliant PMU into the Opal-RT RTS. The RTS-deployed PMU has demonstrated to match the requirements of both transmission and distribution networks. The simulated PMU has been experimentally validated and demonstrated to be well suited for its integration into any RTS.
Screening Procedure for Detection of Antidepressants of the Selective Serotonin Reuptake Inhibitor Type and their Metabolites in Urine as Part of a Modified Systematic Toxicological Analysis Procedure using Gas Chromatography-Mass Spectrometry* (2000)

A gas chromatographic-mass spectrometric (GC-MS) screening procedure was developed for detection of selective serotonin reuptake inhibitors (SSRIs) in urine as part of a systematic toxicological analysis procedure. After acid hydrolysis of one aliquot of urine, another aliquot was added. The mixture was then liquid-liquid extracted at pH 8-9, acetylated, and GC separated. Using mass chromatography with the ions m/z 58, 72, 86, 173, 176, 234, 238, and 290, the possible presence of SSRIs and/or their metabolites could be indicated. The identity of positive signals in such mass chromatograms was confirmed by comparison of the peaks underlying full mass spectra with the reference spectra recorded during this study. The overall recoveries of citalopram, sertraline, and paroxetine ranged between 60 and 80%, and those of fluoxetine and fluvoxamine, which were destroyed during acid hydrolysis, were between 40 and 45%. The coefficients of variation were less than 10-20%, and the limit of detection was at least 100 ng/mL (signal-to-noise ratio = 3). This method allowed the detection of therapeutic concentrations of citalopram, fluoxetine, fluvoxamine, paroxetine, and sertraline in human urine samples.
Immune responses of a liposome/ISCOM vaccine adjuvant against streptococcal fibronectin binding protein 1 (Sfb1) in mice. (2004)

The findings indicated that cisapride caused vasodilatation through the release of nitric oxide (NO) as a result of the release of a substance acting on muscarinic receptors, in the renal vascular bed of the rat. The role of 5-HT4 receptors and prostanoids seemed unlikely.
Assessing control performance in closed-loop anesthesia (2013)

Recently, several control systems for closed-loop anesthesia have been demonstrated both in simulation and clinical studies. A set of performance measures, proposed by Varvel et al., have constituted the standard means of comparing such systems. This paper debates the adequacy of the Varvel measures, as applied to closed-loop anesthesia, and proposes an alternative set of measures. Key features of the proposed measures are: wide acceptance within the control community; reflection of clinical feasibility; separate measures for induction and maintenance of anesthesia; separation of outlier detection and performance evaluation. The proposed measures are descriptive, few, and easy to compute.
Predictive zero-crossing detection algorithm by time localised iterative least-square technique (2011)

A time-localised iterative least square (TILS) based predictive zero-crossing detection (ZCD) algorithm for signals with slowly varying amplitudes and phases has been proposed in this paper. Useful for digital implementation, this technique predicts the zero crossing instant in advance so that further control decision based on ZCD could be performed without delay. The analytical formulation has been verified through experimental results.

Three-dimensional Simulation of Heat Transfer and Stresses in a Steel Slab Caster (2011)

A three-dimensional simulation model is developed of a continuous steel slab caster for optimizing operating conditions and improving slab quality. The heat transfer simulation includes a multi-component steel solidification model and a method to model the characteristics of every single spray nozzle and roll. The temperature predictions are validated using pyrometer data from an operating caster. The stress simulation is based on a visco-plastic constitutive equation for steel, where the semi-solid mush is treated as a compressible porous medium. The stress predictions show regions in the slab where hot tears and cracks are likely to form.
Shared Relay-Based Interference Management Schemes for Device-to-Device Radio Underlaying Cellular Networks (2013)

셀룰러 인프라 구조에 기반하여 셀룰러 스펙트럼을 공유하여 사용하는 D2D (Device-to-Device) 통신은 몇 가지 장점이 있지만, 셀룰러 네트워크 사용자와 동일한 자원을 사용하므로 간섭이 생기는 큰 문제점이 있다. 특히, 다중 셀에서 셀 경계 D2D 사용자와 셀룰러 사용자 간의 간섭 문제는 셀의 중심부에서보다 훨씬 강도가 높게 발생한다. 따라서, 본 논문에서는 인접한 셀들의 중심에 위치한 SRN (Shared Relay Node)이 셀룰러 링크와 D2D 링크 사이에 발생하는 간섭을 효율적으로 관리하는 새로운 방식을 제안한다. 제안하는 SRN은 기존 Type II 릴레이와 같이 데이터 재전송 역할을 수행할 뿐만 아니라, 추가적으로 간섭 관리를 위한 기능을 수행하기 때문에 몇 가지 기능이 새롭게 정의된다. 셀룰러 링크와 D2D 링크 사이에 간섭 관리를 위한 구체적인 방법으로 본 논문에서는 셀 경계영역 사용자들의 간섭 회피를 위한 SRN 기반 자원할당 방법을 제안하고 이들의 성능을 모의실험을 통해 검증하였다. D2D (Device-to-Device) communication on an underlying cellular infrastructure which exploits the same spectrum has several advantages such as increased resource utilization and improved cellular coverage. However, D2D communication system needs to cope with ICI (Inter-Cell Interference) and interference between cellular and D2D links. As a result, macro UEs (User Equipments), especially those located near cell edge, will suffer from serious link performance degradation. We propose a novel interference avoidance mechanism assisted by SRN (Shared Relay Node) in this paper. SRN not only performs data re-transmission as a usual Type II relay but also has several features newly defined to avoid interference between cellular and D2D links. In particular, we suggest resource allocation methods based on the SRN for effective interference avoidance, and evaluate their performance through computer simulations.
Two stage optimization of job scheduling and assignment in heterogeneous compute farms (2004)

Distributed networked computing in a compute farm environment has attracted great attention in recent years. Specialized management system for a compute farm enables heterogeneous distributed resources to be shared in a seamless way between various competing jobs. A key functionality of such system is a scheduler that controls the assignment of jobs to resources. This paper outlines a range of scheduling constrains as well as a list of required scheduling features for a state-of-the-art management system in distributed farm computing. It also presents a novel two stage static-dynamic scheduling algorithm to deal with the scheduling complexity.
Experimental Salmonellosis VII. Comparison of the Immunizing Effect of Live Vaccine and Materials Extracted from <i>Salmonella enteritidis</i> (1966)

Kawakami, Masaya (Gunma University, Maebashi, Japan), Nobutaka Osawa, and Susumu Mitsuhashi. Experimental salmonellosis. VII. Comparison of the immunizing effect of live vaccine and materials extracted from Salmonella enteritidis. J. Bacteriol. 92:1585-1589. 1966.-Attempts were made to isolate the factors of live vaccine which immunize against Salmonella enteritidis infection in mice. Some effective substances were found in cellular extracts of this organism when those extracts were prepared by mild procedures. One of these substances was a heat-labile toxin (toxin L), which was found in an earlier study to be homogeneous as evidenced by chromatographic, ultracentrifugal, and serological analyses and which was phospholipoprotein in nature. Mice immunized with "toxin L" were protected against a 10 MLD challenge infection with a virulent strain to the same extent as animals immunized with live vaccine of an attenuated strain, SER. However, no agglutinin could be detected in sera of the animals given "toxin L." Another effective substance, endotoxin, a heat-stable toxin, which was extracted from the same organisms, demonstrated poor protective effect. Possible mechanisms of immunization with live vaccine in S. enteritidis infection in mice are discussed.
iVector-based prosodic system for language identification (2012)

Prosody is the part of speech where rhythm, stress, and intonation are reflected. In language identification tasks, these characteristics are assumed to be language dependent, and thus the language can be identified from them. In this paper, an automatic language recognition system that extracts prosody information from speech and makes decisions about the language with a generative classifier based on iVectors is built. The system is tested on the NIST LRE09 dataset. The results are still not comparable to state-of-the-art acoustic and phonotactic systems. However, they are promising and the fusion of the new approach with an iVector-based acoustic system is found to bring further improvements over the latter.
ABNORMAL EXPRESSION OF MOLECULAR MARKERS FOR BLADDER IMPERMEABILITY AND DIFFERENTIATION IN THE UROTHELIUM OF PATIENTS WITH INTERSTITIAL CYSTITIS (2004)

The findings reported strongly suggest abnormal differentiation in the IC bladder. The disruption of ZO-1 is similar to that reported in feline IC. Elevated E-cadherin may represent an adaptation to increased bladder permeability.
Strong terahertz absorption using SiO2/Al based metamaterial structures (2012)

Metamaterial absorbers with nearly 100% absorption in the terahertz (THz) spectral band have been designed and fabricated using a periodic array of aluminum (Al) squares and an Al ground plane separated by a thin silicon dioxide (SiO2) dielectric film. The entire structure is less than 1.6 mm thick making it suitable for the fabrication of microbolometers or bi-material sensors for THz imaging. Films with different dielectric layer thicknesses exhibited resonant absorption at 4.1, 4.2, and 4.5 THz with strengths of 98%, 95%, and 88%, respectively. The measured absorption spectra are in good agreement with simulations using finite element modeling.

Physical modeling of voltage-driven resistive switching in oxide RRAM (2012)

Resistive switching random access memory (RRAM) offers fast switching, high endurance and CMOS-compatible integration. Although functional devices below 10 nm have been already demonstrated, assessing the ultimate scaling of RRAM requires a detailed understanding and modeling of switching and reliability processes. This work discusses the modeling of bipolar switching in RRAM. An analytical model is first introduced to describe the temperature- and field-accelerated growth of the conductive filament (CF) induced by ion migration. The analytical model accounts for time-resolved data of the set transition, highlighting the central role of voltage as the driving parameter for set/reset transitions. The analytical model also accounts for the switching parameters as a function of the compliance current. A numerical model is then presented, allowing for a detailed description of the gradual increase during the reset transition. The numerical model highlights the different CF morphology in programmed states obtained by either set or reset. The improved insight into the switching process and the newly developed simulation tools enable device design, reliability prediction and materials engineering in RRAM.
Imaging and characterization of acute myocardial infarction in vivo by gated nuclear magnetic resonance. (1984)

Imaging by nuclear magnetic resonance (NMR) techniques has been shown to provide high-contrast resolution between soft tissues and characterization of normal and pathologic tissues by differences in magnetic relaxation times. The current study was designed to determine whether electrocardiogram (ECG)-gated NMR imaging of the canine heart in vivo could distinguish normal from infarcted myocardium without the use of intravenous paramagnetic contrast agents. Seven dogs were studied by ECG-gated NMR imaging in vivo (spin-echo technique) with a 0.35 Tesla superconducting magnet at 2 to 7 days after ligation of the left anterior descending coronary artery. In six of the seven dogs, signal intensity was increased in the anterior wall compared with the remainder of the left ventricle; this region of high signal intensity corresponded to the area of myocardial infarction demonstrated at postmortem examination. The signal intensity of the infarcted region was 66 +/- 27% greater than that of normal myocardium (p less than .01). The T2 (spin-spin) relaxation time was 69 +/- 3% longer in the infarcted myocardium as compared with normal myocardium (p less than .01). The NMR images from the seventh dog had uniform signal intensity throughout the myocardium of the left ventricle. An infarct was not evident on postmortem examination in this dog. Thus gated NMR imaging in vivo by the spin-echo technique displays acute myocardial infarctions as regions of high signal intensity without the use of contrast media. The infarct is characterized by a prolonged T2 relaxation time.
Study of gaseous substrate fermentations: Carbon monoxide conversion to acetate. 2. Continuous culture (1989)

Abstract The fermentation of gaseous substrates such as CO, H 2 , and CO 2 may be performed in a continuous stirred tank reactor, as well as the traditional batch reactor. In this article, the conversion of carbon monoxide by Peptostreptococcus productus is demonstrated in a stirred tank reactor under both mass transfer‐controlled and nonmass transfer‐controlled conditions. Utilizing a non‐steady‐state procedure, intrinsic rates are evaluated under non‐mass transfer‐controlled conditions in a time period of only 5–6 hours. A steady‐state procedure was used to evaluate CSTR performance under mass transfer‐controlled conditions. The mass transfer coefficient was calculated, followed by the development of a model to predict CSTR behavior for this gas phase substrate.
A model for the loop voltage of reversed field pinches (1987)

A simple model is presented that uses the concept of helicity balance to predict the toroidal loop voltage of reversed field pinches (RFP’s). Data from the RFP’s at Culham [Plasma Phys. Controlled Fusion 27, 1307 (1985)] are used to calibrate and verify the model. The model indicates that most of the helicity dissipation occurs in edge regions that are outside the limiters or in regions where field lines contact the walls. The value of this new interpretation to future RFP and spheromak experiments is discussed.
Characterization of NADPH oxidase 5 in equine testis and spermatozoa (2007)

Reactive oxygen species (ROS) play an important role in normal sperm function, and spermatozoa possess specific mechanisms for ROS generation via an NAD(P)H-dependent oxidase. The aim of this study was to identify the presence of an NADPH oxidase 5 (NOX5) in equine testis and spermatozoa. The mRNA of NOX5 was expressed in equine testis as detected by northern blot probed with human NOX5 cDNA and by RT-PCR. Immunoblotting with affinity purified alpha-NOX5 revealed one major protein in equine testis and other tissues. Immunolocalization of NOX5 showed labeling over the rostral sperm head with some labeling in the equatorial and post-acrosomal regions. In the testis, there was abundant staining in the adluminal region of the seminiferous tubules associated with round and elongating spermatids. The RT-PCR and sequence analysis revealed a high homology with human NOX5. This study demonstrates that NOX5 is present in equine spermatozoa and testes and therefore represents a potential mechanism for ROS generation in equine spermatozoa.
Morphology control of CNT-TiO2 hybrid materials and rutile nanotubes (2008)

Carbon nanotube–inorganic hybrid materials are a new class of functional materials that has gained tremendous interest in recent years due to their exceptional optical, mechanical, electrical and thermal properties. The hydrophobicity of the carbon nanotubes's surface disfavours the adsorption of hydrophilic particles, thus limiting the quality and performance of the hybrid material. We demonstrate that using benzyl alcohol as a surfactant enables TiO2 to interact with the hydrophobic surface of pristine CNTs without the need of covalent functionalisation. The quality of the TiO2 coating is strongly affected by various reaction conditions, including the order of mixing, the choice of drying method, and the water concentration. Furthermore, the effect of heat treatment on the crystallisation of amorphous TiO2 to anatase and the phase transformation from anatase to rutile is discussed in detail. The key achievement of this work is the control of morphology and structure of the TiO2 coating and, after removal of the CNTs, of the rutile nanotubes, which also allows the production of the ideal CNT-TiO2 hybrid material for the desired photochemical, catalytic and sensor applications.
Desorption of positive ions from ionic crystals accompanying 248 nm laser irradiation (2000)

We present a study of the energy distributions of positive ions (Na+, Li+, Ca+, and Mg+) photodesorbed from cleaved NaCl, LiF, MgO, NaNO3, and CaCO3 surfaces during 248 nm excimer laser irradiation at fluences well below the damage thresholds. The observed ion energies are significantly higher than those predicted by already existing models that allow ion rearrangement and relaxation during the electrostatic ion repulsion by the nearby photoionized sites. In contrast to what one would expect, we find that treating the ions as fixed charges and neglecting any ion rearrangement during the emission of the adions describes best the experimentally observed ion energies from all five ionic crystals.
Evaluation of a telepathology system between Boston (USA) and Dijon (France): glass slides versus telediagnostic TV-monitor. (1995)

The objective of this work was to compare diagnoses achieved through the traditional methods of current pathology practice versus diagnoses achieved through a selection of image on a telediagnostic TV-monitor. The Kappa coefficient between the two protocols of k = 0.26 SE(k) = 0.06 z = k/SE(k) = 4.3 (p < 0.001) allows us to conclude that there is a good reliability between video and glass slide diagnoses.
