EMC Computer Modeling Techniques for CPU Heat Sink Simulation (2006)

This paper presents finite-element frequency domain results for electromagnetic radiation emitted from high power microelectronic circuits connected to a heat sink. The heat sink model associated with one of the IEEE EMC challenging problems has been used to investigate three different grounding configurations. A new simulation model for the Intel P4 CPU heat sink is proposed and analyzed. A resonant frequency of 2.6 GHz with a reflection coefficient of 8.3 dB was found for the CPU heat sink. This is close to the IEEE and Bluetooth wireless communication system's operating frequency of 2.4 GHz. An optimal design of the CPU heat sink design should be performed in order to minimize the radiated emission from the CPU heat sink
A null mutation in the photoreceptor guanylate cyclase gene causes the <i>retinal degeneration</i> chicken phenotype (1998)

The retinas of the retinal degeneration (rd) chicken are fully developed and possess normal morphology at hatching but fail to respond to light stimulation. Analyses of retinal cGMP, the internal messenger of phototransduction, show that the amount of cGMP in predegenerate, fully developed rd/rd photoreceptors is 5-10 times less than that seen in normal photoreceptor cells. We show that the low levels of cGMP in rd chicken retina are a consequence of a null mutation in the photoreceptor guanylate cyclase (GC1) gene. Thus, the rd chicken is a model for human Leber's congenital amaurosis. Absence of GC1 in rd retina prevents phototransduction and affects survival of rods and cones but does not interfere with normal photoreceptor development.

AND/OR Graph Representation of Assembly Plans (1986)

A compact representation of all possible assembly plans of a given product using AND/OR graphs is presented. Such a representation forms the basis for efficient planning algorithms that make possible an increase in assembly system flexibility by allowing an intelligent robot to pick a course of action according to instantaneous conditions. The AND/OR graph is equivalent to a state transition graph but requires fewer nodes and simplifies the search for feasible plans. Three applications are discussed: the preselection of the best assembly plan, the recovery from execution errors, and the opportunistic scheduling of tasks. A hypothetical error situation in the assembly of the four-part assembly is discussed to show how a bottom-up search of the AND/OR graph leads to an efficient recovery. The scheduling efficiency using this representation is compared with fixed sequence and precedence graph representations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Optimization of Reburning for Advanced N0<sub>x</sub>Control on Coal-fired Boilers (1989)

This paper summarizes an experimental study which was conducted to investigate the chemical constraints of the reburning process and identify reburning configurations for optimal NOx reduction in coal-fired boilers. Tests were performed on a bench scale tunnel furnace to characterize and optimize the fuel-rich reburning zone and the fuel-lean burnout zone independently. Detailed measurements ofunburned hydrocarbons, CO, NH3, and HCN were made at the reburning zone exit. The influence of the concentrations of reactive species was examined as were temperature effects for both the reburning and burnout zone. Results indicated that reburning zone chemistry was not rate limiting. The impacts of temperature and burnout zone oxidation were of major importance. Integration of the optimum reburning and burnout zone configurations resulted in increased NOx reduction. Over 85 percent reduction in NOx emissions was achieved with ammonium sulfate injection in the burnout zone under optimum reburning conditions.

The Clinical Spectrum of Primary Tuberculosis in Adults (1968)

Thirty-seven adults with tuberculosis are reported, in whom there was evidence (usually tuberculin conversion) that infection was of primary type. The clinical spectrum of primary tuberculosis ranges from a total lack of symptoms in most to massive miliary tuberculosis in a few. Between these extremes, 9 were observed with minor clinical illness accompanied by parenchymal infiltrate, 11 with pleural effusion, and 16 with chronic tuberculosis. Chronic lesions appeared in some at the site of the primary implantation but were more common in the apex, probably because of hematogenous seeding there in the course of the primary infection. Of particular interest were 16 patients in whom primary tuberculosis progressed within a few months or years into chronic pulmonary tuberculosis; reinfection appeared to play no role. Such progression supports the "unitary concept" of tuberculosis recently advocated (1-3). Whenever tuberculin-negative persons (even adults) are exposed to an open case of tuberculosis, infection may take place and be treacherous: primary tuberculosis is difficult to recognize because of mildness of illness, tendency to spontaneous "healing," and lack of prior tuberculin data in most cases. Despite absence of initial illness, primary tuberculosis may progress either sooner or later to chronic tuberculosis. Prevention of serious complication of primary infection can be accomplished by two means: vaccination of persons who must be exposed in work (Peace Corps workers, etc.) with Calmette-Cuérin bacillus to prevent infection, or prophylactic chemotherapy with isoniazid (INH) for those in whom infection has already occurred.
Quality-of-service routing in optical networks (1997)

Influence of Different Electron Donors and Acceptors on Dehalorespiration of Tetrachloroethene by <i>Desulfitobacterium frappieri</i> TCE1 (1999)

Strain TCE1, a strictly anaerobic bacterium that can grow by reductive dechlorination of tetrachloroethene (PCE) and trichloroethene (TCE), was isolated by selective enrichment from a PCE-dechlorinating chemostat mixed culture. Strain TCE1 is a gram-positive, motile, curved rod-shaped organism that is 2 to 4 by 0.6 to 0.8 microm and has approximately six lateral flagella. The pH and temperature optima for growth are 7.2 and 35 degrees C, respectively. On the basis of a comparative 16S rRNA sequence analysis, this bacterium was identified as a new strain of Desulfitobacterium frappieri, because it exhibited 99.7% relatedness to the D. frappieri type strain, strain PCP-1. Growth with H(2), formate, L-lactate, butyrate, crotonate, or ethanol as the electron donor depends on the availability of an external electron acceptor. Pyruvate and serine can also be used fermentatively. Electron donors (except formate and H(2)) are oxidized to acetate and CO(2). When L-lactate is the growth substrate, strain TCE1 can use the following electron acceptors: PCE and TCE (to produce cis-1,2-dichloroethene), sulfite and thiosulfate (to produce sulfide), nitrate (to produce nitrite), and fumarate (to produce succinate). Strain TCE1 is not able to reductively dechlorinate 3-chloro-4-hydroxyphenylacetate. The growth yields of the newly isolated bacterium when PCE is the electron acceptor are similar to those obtained for other dehalorespiring anaerobes (e.g., Desulfitobacterium sp. strain PCE1 and Desulfitobacterium hafniense) and the maximum specific reductive dechlorination rates are 4 to 16 times higher (up to 1.4 micromol of chloride released. min(-1). mg of protein(-1)). Dechlorination of PCE and TCE is an inducible process. In PCE-limited chemostat cultures of strain TCE1, dechlorination is strongly inhibited by sulfite but not by other alternative electron acceptors, such as fumarate or nitrate.
A Note - Production of Vinegar from Whey (2003)

Cheese whey supplemented with lactose was employed to produce vinegar. Whey was first transformed into an alcoholic beverage via fermentation with the yeast Kluyveromyces fragilis, and then the alcoholic product was employed as a substrate for an acetic acid fermentation. The bacteria used for the acetic acid production process were isolated from a starter culture provided by a vinegar factory. The bacteria employed were classified as Acetobacter pasteurianus. The vinegar obtained had a concentration of acetic acid between 5 and 6% (v/v). Ethyl acetate and fusel alcohols (isobutanol, 2-methyl-1-butanol and 3-methyl-1-butanol) were detected in the final product. The process and the substrates employed satisfied FAO requirements that the product was acceptable for human consumption. The efficiency of bio-transformation of ethanol into acetic acid was 84%.
Amplification of evoked potentials recorded from mouse hippocampal slices by very low repetition rate pulsed magnetic fields (2004)

The influence of low repetition rate pulsed magnetic fields (LRMF) on the evoked potential (population spike) recorded from mouse hippocampal slices was investigated. LRMF were applied according to two protocols. In protocol A, LRMF applied with a constant strength (15 mT) and frequency ranging from 0.03 to 0.5 Hz resulted in an amplification of the potential. Although the frequency of 0.16 Hz was the most effective, enhancing the population spike by over 280%, it also caused an increase in spontaneous activity, seizures, and cessation of neuronal activity in 50% of the slices. In protocol B, LRMF were applied with a variable intensity (9-15 mT) and in cycles of different duration ranging from 5 to 20 min. While an increase in the amplitude of the population spike was observed in all slices exposed to LRMF applied according to protocol B, the longest exposure was the most effective. Neither seizures nor an increase in the spontaneous activity were observed in this group of the slices. These results support and extend our previous data and characterize further the relation between the pattern of applied magnetic fields and their influence on the nervous system.
Application of Bi-State Magnetic Material to an Automotive IPM Starter/Alternator Machine (2005)

A new bi-state soft magnetic material has been developed that can have its normally high magnetic permeability reduced permanently to that of air by means of heat treatment. As a result, localized heating via laser or other means can be used to locally "unmagnetize" regions in machine laminations while retaining the high permeability of adjacent untreated regions. A 6 kW interior permanent magnet (IPM) direct-drive starter/alternator machine was used as the target for this investigation. Two alternative designs for the same set of starter/alternator specifications are presented using the new magnetic material for the rotor laminations. Lumped-parameter magnetic circuit models including saturation were used to design both machines and the electromagnetic performance results were subsequently confirmed using finite element analysis (FEA). These results indicate that the performance specifications can be met using this new material while significantly increasing the mechanical integrity of the rotor at high speeds. Advantages and limitations of using this new bi-state magnetic material in IPM machine designs for starter/alternators and other applications are discussed.

Manufacturing processes of soft magnetic composite cores for permanent magnet machines (2017)

By using the low mass density compaction, the electrical machine with soft magnetic composite (SMC) cores has shown its great advantage of the low manufacturing cost over that with silicon steels, especially in the mass production. For the laboratory prototype, wire cutting method is widely used to build the SMC cores for electrical machine. However, cutting the SMC preform block can destroy the magnetic properties of the SMC material, making that the electrical machine made in the laboratory cannot have the same performance as that in the mass production. To minimize the gap between the laboratory prototype and the mass production, the SMC cores should be made by the die compaction. However, to achieve high mass density, the compact pressure must be high and the productivity is low. On the other hand, low mass density compaction would greatly increase the productivity, but the core performance may deteriorate, which can be dealt with careful design and optimization of electrical machine. This paper presents our recent investigation on the manufacturing process of soft magnetic cores. The details of designing the die tools and building the SMC cores by using these tools are described.
Radio-frequency molecular-beam-epitaxy growth of III nitrides for microsensor applications (2001)

To date, GaN-based compounds have proven commercially viable for optoelectronic devices such as light-emitting diodes (LEDs), laser diodes, and UV detectors, and are also under investigation for use in high-power, high-temperature electronics. Other areas in which the III nitrides could be especially beneficial are in high-energy particle detectors and in narrow-band optical sensors for the UV/visible spectral range. In addition to the inherent thermal, mechanical, and chemical stability of III nitrides, such devices would benefit from the larger band gap, higher breakdown, and insulating properties of GaN and related alloys. The surface quality of nitride materials is generally good, and this is very important for fabrication of optical devices. The specific characteristics of the III-nitride layers can be achieved by appropriate substrate selection and precise control over the material growth process. In this article, results on radio-frequency molecular-beam-epitaxy growth of GaN, AlN, AlGaN, and InGaN layers on sapphire and silicon substrates for optoelectronic sensor development applications are presented. Growth of high-quality p-GaN layers with hole concentration of up to ∼5×1017 cm−3 were realized and used in Schottky barrier light-emitting and photodiode structures. AlGaN layers with an Al mole fraction up to 42% as measured by cathodoluminescence, and AlN layers with breakdown fields of 333 V/μm are currently being investigated for applications as insulating layers and active layers, respectively, for devices with an UV-extended spectral range such as hot-electron-based avalanche LEDs and photodiodes.
Convergent and divergent effects of costimulatory molecules in conventional and regulatory CD4 <sup>+</sup> T cells (2012)

Costimulatory molecules of the CD28 family on T lymphocytes integrate cues from innate immune system sensors and modulate activation responses in conventional CD4(+) T cells (Tconv) and their FoxP3(+) regulatory counterparts (Treg). To better understand how costimulatory and coinhibitory signals might be integrated, we profiled the changes in gene expression elicited in the hours and days after engagement of Treg and Tconv by anti-CD3 and either anti-CD28, -CTLA4, -ICOS, -PD1, -BLA, or -CD80. In Tconv, a shared "main response" was induced by CD28, ICOS, and, surprisingly, BTLA and CD80, with very limited CD28-specific (primarily Il2) or ICOS-specific elements (including Th1 and Th2 but not the follicular T signature). CTLA4 and PD1 had a very subtle impact in this system, similarly inhibiting the response to anti-CD3. Treg responded to the same costimulatory hierarchy and to the same extent as Tconv, but inducing different clusters of genes. In this reductionist system, costimulatory or coinhibitory engagement mainly elicits generic responses, suggesting that the variability of their effects in vivo result from temporal or anatomical differences in their engagement, rather than from inherently different wiring.
Analysis and Problem Statements for Interworking between 5G Network Slicing and Transport Network (2018)

This document describes problem statements for realizing an end-to-
end network slicing that is expected to provide service-oriented
communications between users and applications. 3GPP introduced the
network slicing concept in the 5G architecture (3GPP Release 15),
however, it mainly focuses on mobile access and core domains. In order
to reap the benefit of the concept, a network slicing needs to be
designed across multiple domains of the network including non-3GPP
parts. This document analyzes the current 3GPP 5G network slicing
architecture and summarizes problem statements for the interworking
between the 5G network slicing and the transport network.
The influence of amino substitutions within the mature part of an Escherichia coli outer membrane protein (OmpA) on assembly of the polypeptide into its membrane. (1988)

The membrane part of the 325-residue outer membrane protein OmpA of Escherichia coli encompasses residues 1-177. This part is thought to cross the membrane eight times in antiparallel beta-strands, forming four loops of an amphipathic beta-barrel. With the aim of gaining some insight into the mechanism of sorting, i.e. the way the protein recognizes and assembles into its membrane, a set of point mutants in the ompA gene has been generated. Selection for toxicity of ompA expression following mutagenesis with sodium bisulfite yielded genes with multiple base pair substitutions, the majority of which resulted in amino acid substitutions in the membrane moiety of the protein. None of the altered proteins was blocked in membrane incorporation. A proline residue exists at or near each of the presumed turns at the inner side of the outer membrane. Using oligonucleotide-directed mutagenesis, each of them was replaced by a leucine residue which is thought to be a turn blocking residue. None of these proteins had lost the ability to be incorporated into the membrane. Apparently, leucine residues are tolerated at turns in this protein. To interfere with the formation of antiparallel beta-strands, four double mutants were prepared: ompA-ON3 (Ala11----Pro, Leu13----Pro), -ON4 (Ala11----Asp, Leu13----Pro), -ON5 (Gly160----Val, Leu162----Arg), and -ON6 (Leu164----Pro, Val166----Asp). The former three proteins and even quadruple mutants consisting of a combination of ompA-ON2 or -ON4 with -ON5 were not defective in membrane assembly. In contrast, the OmpA-ON6 protein was translocated across the plasma membrane but could not be incorporated into the outer membrane. It is concluded that at least one rather small area of the polypeptide is of crucial importance for the assembly of OmpA into the outer membrane.
Process Technology Variation (2011)

Moore's law technology scaling has improved performance by five orders of magnitude in the last four decades. As advanced technologies continue the pursuit of Moore's law, a variety of challenges will need to be overcome. One of these challenges is the management of process variation. This paper discusses the importance of process variation in modern transistor technology, reviews front-end variation sources, presents device and circuit variation measurement techniques, including circuit and memory data from the 32-nm node, and compares recent intrinsic transistor variation performance from the literature.
