Odor and flavor contribution of 2‐pentyl pyridine to soy protein isolates (1997)

Abstract Total lipid extracts from two commercial soy protein isolates (SPI) were subjected to analyses by gas chromatography/olfaction by using capillary columns with stationary phases of three different polarities. With Kovats indices to identify the location of the odorous compounds on chromatograms produced with the same lipid extracts by gas chromatography/mass spectroscopy, the corresponding mass spectra of clearly distinguishable odors were examined. Compounds, tentatively identified by their mass spectra, were confirmed by retention times (on all three stationary phases), odor intensity, and odor description when compared with standards. Major odorous compounds identified included 2‐methyl butyric acid methyl ester, hexanal, butyric acid, and 2‐pentyl pyridine. Subsequent sensory analyses demonstrated that the mean levels of 2‐pentyl pyridine found in two SPI (0.28 and 1.01 ppm), combined with its repulsive flavor profile (throat‐catching and grassy in water) and extremely low flavor threshold level (0.000012 ppm), make it a major contributor to the undesirable flavor of SPI. Its mean contents in SPI were 23,333 and 84,167 times greater, respectively, than its flavor threshold. The level of hexanal was 112 and 201 times, respectively, above its flavor threshold, and the level of 2‐pentyl furan in each SPI was 433 and 592 times, respectively, above its flavor threshold, which indicates that these two compounds make relatively minor contributions to the flavor of SPI.
Identification of a Core Set of 58 Gene Transcripts With Broad and Specific Expression in the Microvasculature (2008)

We have used a combination of publicly available and own microarray data to identify 58 gene transcripts with broad yet specific expression in microvascular endothelium. Most of these have unknown functions, but many of them are predicted to be cell surface expressed or implicated in cell signaling processes and should therefore be explored as putative microvascular drug targets.
The Survival of Human Skin Stored by Refrigeration at 4°C in McCoyʼs 5A Medium: Does Oxygenation of the Medium Improve Storage Time? (1998)

To establish the viable storage time of human skin stored by refrigeration at 4 degrees C in McCoy's 5A medium and to establish whether oxygenating the medium improves the viable storage time, the following experiment was conducted. Eighty discs of human split-thickness skin graft, each 3 mm in diameter, were stored in 40 sterile sealable containers under four different conditions: in 0.9% saline, in McCoy's 5A medium, in oxygenated McCoy's 5A medium, and in carbon dioxide supplemented McCoy's 5A medium. Skin graft viability was assessed using tissue culture. Skin stored in saline was viable for only 1 week, whereas skin stored in McCoy's 5A medium and in oxygenated McCoy's 5A medium was viable for 4 weeks. Skin stored in carbon dioxide supplemented McCoy's 5A solution did not even survive the first week. These findings show that McCoy's 5A medium allows at least 4 weeks of viable human skin storage by refrigeration at 4 degrees C. Furthermore, oxygenating the medium does not seem to improve the viable storage time, and carbon dioxide supplementation is detrimental. The advantages of skin storage by refrigeration and the implications of the above findings are discussed. A clinical case in which split-thickness skin was stored for approximately 5 weeks and still resulted in good graft take is quoted as an example of our experience with the use of McCoy's 5A medium.
Fiber optic health monitoring of civil structures using long gage and acoustic sensors (2005)

Structural health monitoring with optical fibers provides practical sensing capabilities in many applications including in aeronautics and mechanical structures. A variety of optical fiber sensors have been used including Bragg gratings, intensity or amplitude sensors, and Fabry–Perot ones. Civil structures pose further challenges in monitoring mainly due to their large dimensions, diversity as well as heterogeneity of materials involved, and hostile construction environment. Monitoring of strains, deformations, and deflections provides clues essential for evaluation of design parameters and behavior under service loads. Long gage distributed or multiplexed sensors are excellent candidates for such applications. On the other hand, detection of structural damage and anomalies such as cracking in concrete, splintering of fibers in composites, and fracturing of welds and connections are best accomplished by acoustic sensors. This paper describes principles involved in serial multiplexing of two kinds of optical fibers, namely long gage and acoustic sensors. Both sensor types offer promise in structural health monitoring of large civil structural systems. Representative examples are introduced and described in detail.
Electro-optical serrodyne frequency translator for λ=1.3μm (1985)

Sparse spatio-temporal representation of joint shape-motion cues for human action recognition in depth sequences (2013)

The availability of 3D sensors has recently made it possible to capture depth maps in real time, which simplifies a variety of visual recognition tasks, including object/action classification, 3D reconstruction, etc.We address here the problems of human action recognition in depth sequences. On one hand, we present a new joint shape-motion descriptor which we call as 3D Spherical Histogram of Oriented Normal Vectors (3DS-HONV), since it is a spatio-temporal extension of the original HONV quantized in a 3D spherical coordinate. We further prove that the Optical Flow fields in depth sequences could be used in conjunction with the presented descriptor to augment the ability of capturing in-plane movements; the experiments later show that this combination is more efficient than the standalone 3DS-HONV. In addition, a discriminative dictionary learning and feature representation via Sparse Coding is applied to proposed descriptors to relieve the intrinsic effects of noise and capture high-level patterns. By learning these sparse and distinctive representations, we demonstrate large improvements over the state-of-the-art on two challenging benchmarks, which results with an overall accuracy of 91.92% on the MSRAction3D and 93.31% on the MSRGesture3D datasets, respectively.
Utilization of 4-.BETA.-Galactosyl-Lactose by the Intestinal Bacteria. (1991)

Utilization of the 4-β-galactosyl-lactose, O-β-D-galactopyranosyl-(1→4)-0-β-D-galactopyranosyl-(1→4)-D-glucopyranose, by the intestinal bacteria was investigated. The saccharide was utilized by all species of Bifidobacterium, whereas it was not assimilated by Escherichia coli and almost all species of Clostridium tested. The growth-promoting effect of the 4-β-galactosyl-lactose was specific for bifidobacteria being classified as beneficial intestinal bacteria.
Imaging Alternative Splicing in Living Cells (2004)

We have developed an in vivo reporter of alternative splicing decisions that allows for the determination of FGF-R2 splicing patterns without the destruction of cells. This method has broad applications, including the study of other alternatively spliced genes in tissue culture and in whole animals, and may be useful in creating imaging markers for the study of tumor progression and metastasis. In this chapter, the authors present one example of this method using fluorescence reporters. As with any new assay, a series of experiments were performed to validate the method. This chapter documents some of these experiments.
Communication driven remapping of processing element (PE) in fault-tolerant NoC-based MPSoCs (2017)

We propose a remapping algorithm to tolerate the failures of Processing Elements (PEs) on Multiprocessor System-on-Chip. A new graph modeling is proposed to precisely define the increase of communication cost among PEs after remapping. Our method can be used not only to repair faults but also to improve the communication cost of given initial mapping results. Experimental results show that under multiple failures, the communication cost by our method is 43.59% less on average compared with that by previous work [1] using the same number of spare PEs. Moreover, the communication cost is further reduced by 4.16% after applying our method to initial mappings produced by NMAP [2].
Phenylated imide–quinoxaline copolymers (1970)

Abstract Phenylated, ordered imide–quinoxaline copolymers of high oxidative‐thermal stability were prepared by one‐step solution condensation of aromatic tetraamines with N,N ′‐bis(4‐benzilyl)pyromellitimide. Polymerization in m ‐cresol leads to high molecular weight polymers that remain soluble. Thermal gravimetric analysis and isothermal decomposition at 400°C shows that these polymers are as stable as polyimides or polyquinoxalines. The polymer decomposition temperatures range between 495 and 550°C, depending upon structure. Also, the rate of isothermal decomposition at 400°C in air showed a strong dependency of weight loss on structure. Tough films were cast from solution.

Atmospheric Pressure Radio Frequency Glow Discharges in Argon: Effects of External Matching Circuit Parameters (2007)

Numerical simulations of radio frequency atmospheric pressure argon glow discharges were performed using a one-dimensional hybrid model. The discharge simulations were carried out for a parallel plate electrode configuration with an inter-electrode gap of 1.0 mm together with an external matching circuit. The external matching circuit parameters were found to have significant effect on the discharge characteristics. The results indicate that the discharge can operate at either the α or γ mode depending on the matching circuit parameters. The two modes of operation were found to be distinctly different. The predicted Ar∗ density was considered to provide qualitatively the visual appearance of the α or γ mode discharge. The α mode was found to have a luminous region in the center of the discharge. On the other hand, the γ mode had luminous regions very close to the electrodes which were followed by alternating dark and bright regions. The appearance of the simulated γ mode was found to resemble that of an atmospheric pressure direct current glow discharge. The predicted gas temperature indicated the γ mode to have higher gas temperature compared with the α mode.
Novel mutations in the gene encoding ATP-binding cassette 1 in four Tangier disease kindreds (2000)

Tangier disease (TD) is an autosomal co-dominant disorder in which homozygotes have a marked deficiency of high density lipoprotein (HDL) cholesterol and, in some cases, peripheral neuropathy and premature coronary heart disease (CHD). Homozygotes are further characterized by cholesteryl ester deposition in various tissues throughout the body, most notably in those of the reticuloendothelial system. Several studies have demonstrated that the excess lipid deposition in TD is due to defective apolipoprotein-mediated efflux of cellular cholesterol and phospholipids. Although much progress has been made in our understanding of the metabolic basis of TD, the precise molecular defect had remained elusive until very recently. By positional cloning methods, we: 1) confirm the assignment of TD to chromosome 9q31, 2) provide evidence that human ATP-binding cassette-1 (hABC-1) maps to a 250 kb region on 9q31, and 3) describe novel deletion, insertion, and missense mutations in the gene encoding hABC-1 in four unrelated TD kindreds. These results establish a causal role for mutations in hABC-1 in TD and indicate that this transporter has a critical function in the regulation of intracellular lipid trafficking that dramatically affects plasma HDL cholesterol levels.
Surprisingly stable ammonium ion complex of a non-cyclic crown-type polyether: solid and solution studies (2010)

The first crystal structure of an NH4+ ion complex with 1,13-bis(8-quinolyl)-1,4,7,10,13-pentaoxatridecane (L), a representative non-cyclic analogue of 18-crown-6, is reported along with the characteristics of the complex’s solution; very interestingly, L forms a more stable complex with the NH4+ ion than does 18-crown-6 by the formation of unique recognition tetrahedral-type hydrogen bonds.
A Cost Effective Pipelined Divider for Double Precision Floating Point Number (2006)

The growth of high-performance application in computer graphics, signal processing and scientific computing is a key driver for high performance, fixed latency, pipelined floating point dividers. Solutions available in the literature use large lookup table for double precision floating point operations. In this paper, we propose a cost effective, fixed latency pipelined divider using modified Taylor-series expansion for double precision floating point operations. We reduce chip area by using a smaller lookup table. We show that the latency of the proposed divider is 49.4 times the latency of a full-adder. The proposed divider reduces chip area by about 81% than the pipelined divider in (Jong-Chul Jeong, 2004) which is based on modified Taylor-series

Two-step granular activated carbon filtration in drinking water treatment (2002)

In the treatment of Finnish surface waters, the main objective is to reduce natural organic matter (NOM) before the water is disinfected. In many treatment plants, granular activated carbon (GAC) filtration is applied for the enhanced removal of NOM after conventional treatment. The aim of this study was to assess the performance of two-step GAC filtration in NOM removal and to determine its effects on the water quality in the distribution system. Furthermore, the optimal operation conditions of the existing process scheme at Helsinki Water's treatment plant after installing two-step GAC filtration and UV disinfection was evaluated.\n\nThe study revealed that the major factors influencing the effective NOM removal in GAC filtration are the choice of GAC type and the frequency of regeneration. Other factors, such as empty bed contact time and biological degradation rate, were of minor importance. However, even the fully exhausted "old" GAC effectively decreased the assimilable organic carbon (AOC) and the regrowth of heterotrophic bacteria in the distribution system. The most interesting finding of the study was that introducing GAC filtration and UV disinfection increased the nitrification in the chloraminated distribution system.\n\nIntroducing GAC filtration is a challenge for the more efficient use of the existing treatment process. Although optimal ozonation probably provided the highest biological activity in the following exhausted GAC filters, alone it does not justify the use of ozone. After installing GAC filtration and UV disinfection, the role of ozone is rather to provide an additional barrier against unexpected changes in the source water quality.
Detection of High Impedance Fault in Power Distribution Systems Using Mathematical Morphology (2012)

A high impedance fault (HIF) is characterized by a small, nonlinear, random, unstable, and widely varying fault current in a power distribution system. HIFs draw very low fault currents, and hence are not always effectively cleared by conventional overcurrent relays. Various schemes are proposed to detect such faults. This paper presents a method to detect HIFs using a tool based on mathematical morphology (MM). The method is implemented alongside the conventional overcurrent relay at the substation to improve the performance of this relay in detecting HIFs. It is rigorously tested on standard test systems using PSCAD/EMTDC® to generate test waveforms, and Matlab® to implement the method. Simulation results show that the proposed method is fast, secure, and dependable.
Comparison of Axial Flux Permanent Magnet Synchronous Machines With Electrical Steel Core and Soft Magnetic Composite Core (2017)

This paper presents a comparison of axial flux permanent magnet machines (AFPMs) with an electrical steel core and that with a soft magnetic composite (SMC) core. SMCs have several advantages such as low core loss and low eddy current loss. However, compared with electrical steel, SMCs have poor magnetic properties such as low flux density saturation and unsaturated relative permeability. The analysis of the electromagnetic characteristics in a wide frequency range revealed that for an AFPM using an electric steel core, the performance was excellent in a low-frequency range; however, for an AFPM using an SMC core, the performance improves with an increase in frequency. Finally, the operation area of an AFPM using an SMC core is proposed.
Liquid Crystalline Properties of 4-Methyl-, 4-Ethyl- and 4-Propyl-4'-alkyloxyazobenzenes (2002)

For these three homologous series, temperatures and enthalpies of phase transitions and the types ofmesophases are presented. The influence ofthe alkoxy chain length on the sequence of mesophases, temperatures of the phase transitions and the entropy effects are discussed.

The growth of wireless Internet enables users to connect to the network from different locations using mobile Interne
Effects of network delay on a collaborative motor task with telehaptic and televisual feedback (2004)

The incorporation of haptic interfaces into collaborative virtual environments is challenging when the users are geographically distributed. Reduction of latency is essential for maintaining realism, causality and the sense of co-presence in collaborative virtual environments during closely-coupled haptic tasks. In this study we consider the effects of varying amounts of simulated constant delay on the performance of a simple collaborative haptic task. The task was performed with haptic feedback alone or with visual feedback alone. Subjects were required to make a coordinated movement of their haptic displays as rapidly as possible, while maintaining a target simulated spring force between their end effector and that of their collaborator. Increasing simulated delay resulted in a decrease in performance, either in deviation from target spring force and in increased time to complete the task. At large latencies, there was evidence of dissociation between the states of the system that was observed by each of the collaborating users. This confirms earlier anecdotal evidence that users can be essentially seeing qualitatively different simulations with typical long distance network delays.
Effects of REM sleep and ambient temperature on hot flash-induced sleep disturbance (2006)

In the second half of the night, rapid eye movement sleep suppresses hot flashes and associated arousals and awakenings. This may explain previous discrepancies between self-reported and laboratory-reported data in postmenopausal women with hot flashes.
Knowledge worker constraints in the productive use of information technology (1999)

The impact of Information Technology on managing enterprises continues unabated. Realizing the potential of IT has become a critical concern as the investments mount exponentially. The prosperity of organizations requires that IT resources are used productively by people.This study tests for constraints in the productive use of Information Technology by knowledge workers in organizations. The QRS® NUD*IST™ analysis package is used to analyze one hundred and twenty-five knowledge workers' written assessments. The non-directive assessments identified infrastructure, technical, information, and task categories of issues. The sub-categories of these issues lead to the identification of the structure of constraints.Information Technology can be better utilized to address users needs. The analyses reveal that infrastructure issues are critical. Organizations are not providing support necessary to utilize IT effectively. Technical issues are also important. The expected advantages of IT, such as speed and reliability, do not match knowledge workers expectations. Instead, they are perceived as constraints. The gap between expected and realized IT capabilities is much larger than expected. This leads to difficulties in alienation, anxiety, overload, and lower productivity. Knowledge workers offered their own solutions to resolving the principal, and sub-categories of constraints. Their views provide the basis for addressing practical problems and future research directions in improving knowledge worker productivity using Information Technology.
An overview of a network design system (1980)

During the past few years there has been an increasing trend toward the development of on-line computer systems. By 1980 it is estimated that 70--80 percent of all larger computer installations will support some networking capability. This trend has resulted in an increasing network user population and varying applications for computer-communication networks. Furthermore, due to economics, the prevalence of single-application networks is giving way to increasing numbers of multi-application networks.
