Usage of ITO to Prevent Spacecraft Charging (1982)

FEP Teflon, Kapton and Quartz mirror coated with Indium Oxide or Indium Tin Oxide were evaluated as non-charging spacecraft thermal control surfaces. Coatings from 50Å to 600Å were evaluated under environmental conditions of: solar visible, UV and X-rays; thermal shock; extreme temperatures; abrasion and handling; high energy radiation; humidity; vacuum; and chemicals. Material parameters measured were: electrical resistivity, optical absorptivity and emissivity, adhesion, abrasion resistance, and flexibility. The samples qualify for space use and do not arc under space simulating irradiation. Coating "grounding" techniques were also developed.
An intelligent optimization approach for storage space allocation at seaports: A case study (2015)

Storage space allocation problem at container terminals is NP-hard combinatorial optimization problem. This paper proposes a new approach based on genetic algorithm to optimize the solution for storage space allocation problem in container terminal at seaports. A new mathematical model is formulated to avoid bottlenecks in container yard operations, and to minimize vessels service time in port. Also, a simulation model using discrete event simulation tool is conducted to optimize the solution for storage space allocation problem is presented in this study. The proposed approach is applied on a real case study data of container terminal at Damietta port. The computational results show the effectiveness of the proposed approach.
A LQR Controller Design for Active Vibration Control of Flexible Structures (2008)

This paper demonstrates an active vibration control system of flexible structures by using piezoelectric sensors and actuators. A set of vibration control equations, sensing equations and actuating equations are derived through using the modal theory for piezoelectric flexible structures, then the model is converted into the state space form. With recent developments in sensors/actuators technologies, many researchers have concentrated on control methods for suppressing vibration of the structures using smart materials such as piezoelectric transducers (PZT). In this paper, two piezoelectric patches are collocated on both sides of the same position of the structure which used as modal sensors and actuators, and the optimal location of them is ascertained by the function of displacement deflection, a LQR controller is designed based on the independent mode space control techniques to suppress the vibration of the system. Finally, the paper takes a piezoelectric cantilever beam as an example, and gives the control simulation results which demonstrate the effectiveness of the method in this paper.

P-channel, vertical insulated gate bipolar transistors with collector short (1987)

P-channel, collector-shorted, vertical insulated gate bipolar transistors with hexagonal and square cell geometries were studied. The presence of the collector short, surrounding the edges of the device, resulted in a linear I-V region before the conductivity modulation region sets in. The effect of poly-Si overlap and JFET dosage on forward drop and breakdown voltage were analyzed for hexagonal and square DMOS cell geometries. In contrast to the conventional IGBT, the turn-off time increases with increasing collector current A maximum controllable current of -5A (-710A/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> was measured when switching into -300V at room temperature. The built-in anti-parallel diode formed between the collector short and the deep n+ short in the DMOS cells has also been character ized.
The uptake of amino acids by mouse cells (strain LS) during growth in batch culture and chemostat culture: the influence of cell growth rate (1967)

Abstract The uptake of thirteen essential amino acids by mouse LS cells in suspension culture was determined by bacteriological assay methods. Chemostat continuous-flow cultures were used to determine the effect of different cell growth rates on the quantitative amino acid requirements for growth. The growth yields of the cells (Y = g cell dry weight produced/g amino acid utilized) were calculated for each of the essential amino acids. A mixture of the non-essential amino acids, serine, alanine and glycine increased the cell yield from the essential amino acids. The growth yields from nearly all the essential amino acids in batch culture were increased when glutamic acid was substituted for the glutamine in the medium. The growth yields from the amino acids in batch culture were much less at the beginning than at the end of the culture. The highest efficiencies of conversion of amino acids to cell material were obtained by chemostat culture. When glutamic acid largely replaced the glutamine in the medium the conversion of amino acid nitrogen to cell nitrogen was 100 % efficient (that is, the theoretical yield was obtained) at the optimum growth rate (cell doubling time, 43 h). The maximum population density a given amino acid mixture will support can be calculated from the data. It is concluded that in several routinely used tissue culture media the cell growth is limited by the amino acid supply. In batch culture glutamine was wasted by (1) its spontaneous decomposition to pyrrolidone carboxylic acid and ammonia, and (2) its enzymic breakdown to glutamic acid and ammonia, but also glutamine was used less efficiently than glutamic acid. Study of the influence of cell growth rate on amino acid uptake rates per unit mass of cells indicated that a marked change in amino acid metabolism occurred at a specific growth rate of 0.4 day-1 (cell doubling time, 43 h). With decrease in specific growth rate below 0.4 day-1 there was a marked stimulation of amino acid uptake rate per cell and essential amino acids were consumed increasingly for functions other than synthesis of cell material.

A Monoclonal Antibody Against Human MUDENG Protein (2013)

MUDENG (mu-2-related death-inducing gene, MuD) encodes a predicted ∼54-kDa protein in humans, considered to be involved in trafficking proteins from endosomes toward other membranous compartments as well as in inducing cell death. Here we report on the generation of a mouse monoclonal antibody (MAb) against the middle domain of human (h) MuD. This IgG sub 1 MAb, named M3H9, recognizes residues 244-326 in the middle domain of the MuD protein. Thus, the MuD proteins expressed in an astroglioma cell line and primary astrocytes can be detected by the M3H9 MAb. We showed that M3H9 MAb can be useful in enzyme-linked immunosorbent assay (ELISA) and immunoblot experiments. In addition, M3H9 MAb can detect the expression of the MuD protein in formalin-fixed, paraffin-embedded mouse ovary and uterus tissues. These results indicate that the MuD MAb M3H9 could be useful as a new biomarker of hereditary spastic paraplegia and other related diseases.

Protein separation in pH gradients using free‐flow electrophoretic apparatus II. The pH gradients formed by the concentration gradient of boric acid in solutions of borax and mannitol (1985)

Abstract Protein separation was investigated in the free‐flow apparatus using pH gradients generated by a concentration gradient of boric acid in a solution of borax. The linear pH gradient covering the range pH 8.2–9.2 was obtained in a solution of 2.5 mM borax due to the formation of the logarithmic concentration gradient of 0–45 mM boric acid. These pH gradients lacked a conductivity gradient in contrast to borate mannitol pH gradients, described in the joint report. By addition of mannitol into the gradient, at constant concentration, the pH was shifted toward more acidic values in proportion to the amount of mannitol added, without changing the range and shape of the pH gradient. According to this procedure of gradient formation the pH gradients can be obtained within the range from pH 3.5 to 9.2. The gradients were rapidly decaying under the experimental conditions. Thus, isoelectric focusing of proteins could not be achieved, and the separation resulted from electrophoresis in the pH gradient. The results of protein separation in the gradients practically did not depend on the point of injection of the samples into the pH gradient, at least in the cases when the proteins were injected near their isoelectric points.
Design space exploration algorithm for heterogeneous multi-processor embedded system design (1998)

Single-chip multi-processor embedded system becomesnowadays a feasible and very interesting option. What isneeded however is an environment that supports the designerin transforming an algorithmic specification into a suitableparallel implementation. In this paper we present anddemonstrate an important component of such an environment - an efficient design space exploration algorithm. The algorithm can be used to semi-automatically find the bestparallelization of a given embedded application. It employsfunctional pipelining [13] and data set partitioning [16]simultaneously with source-to-source program transformationsto obtain the most advantageous hierarchical parallelizations.
모바일 게임산업환경에서의 개인정보보호에 대한 법정책적 고찰 (2016)

개인정보보호법의 제정·시행 이후 개인정보 보호에 대한 사회적 인식이 높아지고 실질적 보호를 위한 체계가 마련되었지만, 반면 개인정보 관련 모든 분야에 동일하게 적용되는 내용으로 인하여 보다 현실적이고 구체적 상황에 적합한 보호 정책 마련의 목소리 또한 높다. 게임산업의 경우 회원가입이나 본인확인, 연령에 따른 서비스 제공, 결제의 과정 등에서 개인정보의 수집이 이루어지고 그에 따라 개인정보보호법의 규율을 받고 있다. 이러한 법적 규제는 최근 게임산업의 핵심으로 떠오르고 있는 모바일 게임환경에서도 동일하게 적용된다고 보는 것이 일반적인데, 서비스 제공의 메커니즘이 다층적이고 복잡한 모바일 게임환경에 지금의 개인정보보호법의 적용이 적절한지 여부는 살펴볼 필요가 있다. 실제 모바일 게임 서비스의 과정을 넓게 보면 개인정보의 흐름을 쉽게 포착할 수 있지만 이들은 대체적으로 디바이스의 구입, 개통 혹은 앱 구입을 위한 마켓가입, 플랫폼 가입 등 게임서비스 제공 그 자체가 아닌 그 주변에서 이루어지는 과정임에 주목해야 한다. 오히려 게임서비스 자체의 과정에서의 개인정보의 흐름은 필요 최소한으로 한정되어 있고 사실상 존재하지 않는 것으로 보이는데 개인정보 수집·보관으로 인한 법적 부담에서 자유롭고 싶어 하는 사업자들의 의식적인 노력의 결과로 보인다. 이러한 상황에도 불구하고 개인정보보호법이나 게임산업 관련법에서는 게임서비스 제공자에게 개인정보 보호에 대한 일반적이며 상당한 의무를 부담시키고 있는데 실제로 개인정보를 수집하거나 저장하지 않는 일반적 경우에 이러한 규제는 현실적이지 못하다. 따라서 게임산업, 특히 모바일 게임산업환경에 적절한 개인정보보호 정책의 마련이 요구되는데 이를 위해서는 개인정보 흐름의 구체적 상황에 대한 고려가 필수적이라 할 수 있다. 더불어 기술 발전에 상응하는 개인정보의 범위에 대한 논의도 필요하며 모바일 게임환경의 특수성과 글로벌 환경에서의 정책의 효율성을 도모하기 위해 자율규제의 도입도 고려해볼 필요가 있다.
Studies on the Synthesis of Benzimidazo[2,1- <i>a</i> ]isoquinolines (1998)

The reaction of the isocoumarin derivative 1-acetylimino-3-methyl-1 H -2-benzopyran-4-carbonitrile (1a) with aromatic ortho diamines provides entry to the benzimidazo[2,1- a ]isoquinoline and related systems. Various conversions of the methyl and cyano groups in the tetracycles into amide, aldehyde and acid functions have been carried out, along with studies of electrophilic nitration.
Assortment Planning and Inventory Decisions Under a Locational Choice Model (2005)

We consider a single-period assortment planning and inventory management problem for a retailer, using a locational choice model to represent consumer demand. We first determine the optimal variety, product location, and inventory decisions under static substitution, and show that the optimal assortment consists of products equally spaced out such that there is no substitution among them regardless of the distribution of consumer preferences. The optimal solution can be such that some customers prefer not to buy any product in the assortment, and such that the most popular product is not offered. We then obtain bounds on profit when customers dynamically substitute, using the static substitution for the lower bound, and a retailer-controlled substitution for the upper bound. We thus define two heuristics to solve the problem under dynamic substitution, and numerically evaluate their performance. This analysis shows the value of modeling dynamic substitution and identifies conditions in which the static substitution solution serves as a good approximation.
CNV and nervous system diseases – what’s new? (2008)

Several new genomic disorders caused by copy number variation (CNV) of genes whose dosage is critical for the physiological function of the nervous system have been recently identified. Dup(7)(q11.23) patients carry duplications of the genomic region deleted in Williams-Beuren syndrome, they are characterized by prominent speech delay. The phenotypes of Potocki-Lupski syndrome and MECP2 duplication syndrome were neuropsychologically examined in detail, which revealed autism as an endophenotype and a prominent behavioral feature of these disorders. Tandem duplication of LMNB1 was reported to cause adult-onset autosomal dominant leukodystrophy. PAFAH1B1/LIS1 and YWHAE, which were deleted in isolated lissencephaly (PAFAH1B1/LIS1 alone) and Miller-Dieker syndrome (both genes), were found to be duplicated in patients with developmental delay. Finally, two novel microdeletion syndromes affecting 17q21.31 and 15q13.3, as well as their reciprocal duplications, were also identified. In this review, we provide an overview of the phenotypic manifestation of these syndromes and the rearrangements causing them.
Osmium(II) CNN Pincer Complexes as Efficient Catalysts for Both Asymmetric Transfer and H<sub>2</sub> Hydrogenation of Ketones (2008)

Catalysis at a pinch: Osmium CNN pincer complexes [OsCl(CNN)P2] (see graphic) are extremely active and productive catalysts for both the transfer and asymmetric hydrogenation of ketones (TOF≈106 h−1 and TON≈105). High enantioselectivity is achieved in the presence of only 0.005–0.002 mol % of the chiral osmium derivatives. [OsX(CNN)(dppb)] species with X=H and OR are involved in these catalytic TH and HY reactions.

Ankle arthrodesis using an arthroscopic method: Long‐term follow‐up of 34 cases (1996)

Thirty-four ankle arthrodeses performed using an arthroscopic technique were followed for an average of 8 years. The fusion rate was 97% and the average time to fusion was 9 weeks; 86% of patients had good or excellent functional results. There were no wound infections or neurological injuries. There was one malunion and one additional minor complication. The arthroscopic method uses an abrader to denude the joint surfaces of cartilage, followed by screw fixation. The average time to fusion is significantly less than other ankle arthrodesis techniques, which hastens the recovery period. The shorter time to fusion is likely a result of the minimal soft tissue stripping that is performed during the procedure. The low morbidity of this technique eliminates the need for hospitalization in most cases. There were no long-term adverse sequelae. This is the largest reported series of arthroscopic ankle arthrodeses.
Connectionist expert systems (1988)

[Influence of microiontophoretic morphine on nociceptive responses of Pf neurons after lesion of SmI]. (1995)

Neuronal responses in thalamic nucleus parafasciculus (Pf) to microiontophoretic morphine were examined in 20 wistar rats after lesion of SmI. Extracellular recordings were made with five-barreled glass microelectrodes. The results showed that the spontaneous responses of Pf neurons were not statistically changed (n = 11, P > 0.05), but their nociceptive responses were attenuated at 0-8 minutes after iontophoretic morphine (n = 11, P < 0.05). There were statistically significant differences in nociceptive responses between morphine and saline groups at 0-8 minutes after iontophoresis. The results suggest that morphine may be involved in corticofugal modulation of nociceptive responses in thalamic Pf neurons.
Diverse Myocardial Extension and Autonomic Innervation on Ligament of Marshall in Humans (2006)

MB-LA connections were mainly observed at the CS juncture and PV-LA junctions. The association between sympathetic nerve fibers and MBs was distinct at the PV-LA junctions. At the CS juncture, the regression of the sympathetic nerve fibers and the increase of parasympathetic ganglions were observed. The diverse arrangement and autonomic innervation of MBs seem to characterize the LOM region in humans.
The Molecular Mechanisms of Anesthetic Action: Updates and Cutting Edge Developments from the Field of Molecular Modeling (2010)

For over 160 years, general anesthetics have been given for the relief of pain and suffering. While many theories of anesthetic action have been purported, it has become increasingly apparent that a significant molecular focus of anesthetic action lies within the family of ligand-gated ion channels (LGIC's). These protein channels have a transmembrane region that is composed of a pentamer of four helix bundles, symmetrically arranged around a central pore for ion passage. While initial and some current models suggest a possible cavity for binding within this four helix bundle, newer calculations postulate that the actual cavity for anesthetic binding may exist <i>between</i> four helix bundles. In either scenario, these cavities have a transmembrane mode of access and may be partially bordered by lipid moieties. Their physicochemical nature is amphiphilic. Anesthetic binding may alter the overall motion of a ligand-gated ion channel by a "foot-in-door" motif, resulting in the higher likelihood of and greater time spent in a specific channel state. The overall gating motion of these channels is consistent with that shown in normal mode analyses carried out both <i>in vacuo</i> as well as in explicitly hydrated lipid bilayer models. Molecular docking and large scale molecular dynamics calculations may now begin to show a more exact mode by which anesthetic molecules actually localize themselves and bind to specific protein sites within LGIC's, making the design of future improvements to anesthetic ligands a more realizable possibility.

[Pulmonary vascular disease in shunted and nonshunted patients with tetralogy of Fallot]. (1989)

Histometric analysis of pulmonary vascular disease was performed in 21 nonshunted patients and in 13 shunted patients with tetralogy of Fallot and in 29 normal controls. There was no significant difference in the medial thickness of the small pulmonary arteries between cases of tetralogy of Fallot and normal controls. However, the media in the shunted cases of tetralogy of Fallot gave the impression of being thicker than these in the nonshunted cases. Intimal fibrosis, regarded as organized thrombi, and thrombi of small pulmonary arteries were observed generally after 4 years of age in shunted and nonshunted cases of tetralogy of Fallot. Intimal proliferation of musculoelastosis which was formed longitudinal smooth muscle bundles and elastic fibers was characteristic in shunted patients, especially after the central palliation procedure, Waterston anastomosis and modified Blalock-Taussig (B-T) anastomosis using a Gore-Tex tube graft. However, musculoelastosis was not usually seen in the B-T anastomosis cases. Unexpected pulmonary hypertension due to shunt operation is thought to be the cause of musculoelastosis, because musculoelastosis was observed even in a patient with pulmonary hypertension 3 weeks following surgery. We, therefore, recommend original B-T anastomosis as the shunt procedure. When considering use of the other shunt operations which entail pressure load on the pulmonary vascular bed, attention must be given to the size of the anastomosis or artificial tube graft.
PCB integrated inductors for low power DC/DC converter (2003)

This paper discusses the use of printed circuit board (PCB) integrated inductors for low power DC/DC buck converters. Coreless, magnetic plates and closed core structures are compared in terms of achievable inductance, power handling and efficiency in a footprint of 10 /spl times/ 10 mm/sup 2/. The magnetic layers consist of electroplated NiFe, so that the process is fully compatible with standard PCB process. Analytic and finite element method (FEM) methods are applied to predict inductor performance for typical current waveforms encountered in a buck converter. Conventional magnetic design procedures are applied to define optimum winding and core structures for typical inductor specifications. A 4.7 /spl mu/H PCB integrated inductor with dc current handling of up to 500 mA is presented. This inductor is employed in a 1.5 W buck converter using a commercial control integrated circuit (IC). The footprint of the entire converter measures 10 /spl times/ 10 mm/sup 2/ and is built on top of the integrated inductor to demonstrate the concept of integrated passives in power electronic circuits to achieve ultra flat and compact converter solutions.
