Power: a changing commodity. (1991)

"Rapid and tumultuous change in health care as well as business has precipitated a power shift," declares Mr. Hage in this candid discussion of a quality that is both abstract and concrete. Centralized power is no longer the order of the day; in fact, the new stance supports pushing power down into organizations where it can be better used by those closer to the action. The author maintains that effective participants in this new model will learn to share power and respect knowledge as the only tool that wields it.
The complex binary number system (2002)

Conversion algorithms and arithmetic procedures for a (-1 + j)-base binary number allow a given complex number to be represented as one unit. This should simplify the operations involving complex numbers in today's microprocessors. With the division process secure, we can implement the usual algorithms for calculating functions and processes such as logarithms, exponentials and trigonometric functions Currently, work is underway to write Java applets for the algorithms. We are planning to design an arithmetic unit based on the new binary system which will then be implemented using field programmable gate arrays.

Platinum Etching and Plasma Characteristics in RF Magnetron and Electron Cyclotron Resonance Plasmas (1993)

The properties of platinum etching were investigated using both rf magnetron and electron cyclotron resonance plasmas, together with measurement of the plasma parameters. Experiments were performed over a wide pressure range from 0.4 to 50 mTorr in Cl 2 plasmas. In rf magnetron plasmas, the etch rate of Pt was constant at the substrate temperature from 20 to 160°C. The etch rate and the plasma electron density increased with decreasing gas pressure from 50 to 5 mTorr. In ECR plasmas for rf power of 300 W, the etch rate of Pt was almost constant (∼100 nm/min) with decreasing gas pressure from 5 to 0.4 mTorr, while the plasma electron density was gradually increased with decreasing gas pressure. These experimental results were discussed with respect to the relationship between the etch yield and ratio of neutral Cl flux and ion flux incident on the substrate. Submicron patterning (0.5 µm lines & spaces) of platinum masked with photoresist was demonstrated using Cl 2 plasmas in ECR discharges. High accuracy was obtained with no undercutting.
Preamble Structure for MIMO-OFDM Wlan Systems Based on IEEE 802.11A (2006)

This paper proposes a preamble structure for a next-generation high-throughput Wireless LAN physical layer using MIMO-OFDM. The proposed preamble is based on two important criteria as well as those which have already been widely discussed in the literature. One criterion is backward compatibility with legacy devices. The other is accurate AGC for MIMO data payload of the packet. Computer simulations demonstrate that the proposed preamble is superior to the other preambles with respect to these two important criteria

The basic genetic characteristics of the normal cells are conserved in the oral carcinoma-associated fibroblasts, which means the cells have no malignant changes.
A de-centralized scheduling and load balancing algorithm for heterogeneous grid environments (2003)

In the past two decades, numerous scheduling and load balancing techniques have been proposed for locally distributed multiprocessor systems. However they all suffer from significant deficiencies when extended to a Grid environment: some use a centralized approach that renders the algorithm unscalable, while others assume the overhead involved in searching for appropriate resources to be negligible. Furthermore, classical scheduling algorithms do not consider a Grid node to be N-resource rich and merely work towards maximizing the utilization of one of the resources. In this paper, we propose a new scheduling and load balancing algorithm for a generalized Grid model of N-resource nodes that not only takes into account the node and network heterogeneity, but also considers the overhead involved in coordinating among the nodes. Our algorithm is decentralized, scalable, and overlaps the node coordination time with that of the actual processing of ready jobs, thus saving valuable clock cycles needed for making decisions. The proposed algorithm is studied by conducting simulations using the Message Passing Interface (MPI) paradigm.
Agalactosyl IgG in inflammatory bowel disease: correlation with C-reactive protein. (1990)

The proportion of oligosaccharide chains on the Fc fragment of IgG which terminate with N-acetylglucosamine (GlcNAc) rather than galactose is increased in rheumatoid arthritis and tuberculosis, and in sera from patients with Crohn's disease, probably because of decreased activity of a galactosyltransferase in B lymphocytes. We have assayed the prevalence of agalactosyl oligosaccharides on IgG in sera from 67 patients with inflammatory bowel disease (32 ulcerative colitis and 35 Crohn's disease). The prevalence of agalactosyl IgG significantly increases in the majority of Crohn's patients (19/35 patients), and correlates with the level of C-reactive protein (r = 0.79), and inversely with the concentration of serum albumin. Sera from ulcerative colitis patients show less frequent (nine of 32) and less marked rises in agalactosyl IgG, and sera with high C-reactive protein values can contain normal levels. Thus in ulcerative colitis no correlation was seen between the two assays. The diseases in which the percentage of agalactosyl IgG is raised (rheumatoid arthritis, tuberculosis, Crohn's disease and some ulcerative colitis) are characterised by simultaneous T cell mediated granulomatous tissue damage, and acute phase responses. Levels are normal in less tissue damaging granulomatous conditions, including sarcoidosis, and leprosy (except during episodes of erythema nodosum leprosum). We suggest therefore that a raised percentage of agalactosyl IgG is a correlate of a particular type of T cell mediated pathology which may be relevant to the pathogenesis of inflammatory bowel disease.
Effect of Feeding Psyllium and Cholestyramine in Combination on Low Density Lipoprotein Metabolism and Fecal Bile Acid Excretion in Hamsters with Dietary-Induced Hypercholesterolemia (1996)

We wished to determine the effectiveness of submaximal doses of cholestyramine and psyllium given in combination in reversing dietary-induced hypercholesterolemia in Golden Syrian hamsters, and to investigate the mechanism or mechanisms of action through which these agents together decrease plasma low density lipoprotein cholesterol (LDL-C) levels in this model. For 30 days, male hamsters were fed a cholesterol-rich cereal-based diet containing either a submaximal dose of cholestyramine (1% wt/wt) alone or in combination with psyllium (either 2 or 4%), or a high dose of cholestyramine (3%) alone. Although the greatest cholesterol-reducing action was achieved with 3% resin alone, in the animals fed one third as much cholestyramine combined with psyllium (4%) LDL-C production decreased from 288 +/- 15 to 187 +/- 17 micrograms/h per 100 g body weight, the suppression of LDL-receptor activity was almost fully reversed, plasma LDL-C levels were reduced from 90 +/- 8 to 41 +/- 5 mg/dl, and hepatic cholesterol content decreased from 17.1 +/- 1.9 to 2.4 +/- 0.1 mg/g. In the group that received 1% resin alone, the plasma LDL-C and hepatic cholesterol levels were 60 +/- 3 mg/dl and 7.2 +/- 0.6 mg/g, respectively. As compared with animals that received 1% resin alone, those fed both agents manifested higher rates of fecal bile acid excretion and lower levels of intestinal cholesterol absorption. A significant cholesterol-lowering benefit can be derived from using these nonsystemic agents in combination at lower, more tolerable doses.
Modes of action of tunicamycin, liposidomycin B, and mureidomycin A: inhibition of phospho-N-acetylmuramyl-pentapeptide translocase from Escherichia coli (1996)

Using a continuous fluorescence-based enzyme assay, we have characterized the antibacterial agents tumicamycin and liposidomycin B as inhibitors of solubilized Escherichia coli phospho-N-acetylmuramyl-pentapeptide translocase. Tunicamycin exhibited reversible inhibition (Ki = 0.55 +/- 0.1 microM) which was noncompetitive with respect to the lipid acceptor substrate and competitive with respect to the fluorescent substrate analog, dansyl-UDPMurNAc-pentapeptide. Liposidomycin B exhibited slow-binding inhibition (Ki = 80 +/- 15 nM) which was competitive with respect to the lipid acceptor substrate and noncompetitive with respect to dansyl-UDPMurNAc-pentapeptide. These results provide insight into the molecular mechanisms of action of these two classes of nucleoside antibiotics.
Design Criteria of Video Post Production Systems with Optimum Operational Editing Convenience (1979)

In view of the fact that only a limited number of automatic videotape editing systems are available at present in West Germany's broadcasting institutions, the Institut für Rundfunktechnik (IRT) started its own development program for this type of equipment. Some of me results so far obtained are described. Two pilot projects have been undertaken, one being an off-line and the other an on-line videotape editing system. While the off-line system is intended only for post production use, the on-line system can be applied in pre-broadcast program production, in post production work, and in live-program broadcasting. Both systems make use of so-called “intelligent” components (microprocessors); the off-line system uses a central intelligence, whereas the online system makes use of distributed intelligence. Ease of operator manipulation was one of the overriding design criteria. The subdivision of routine tasks, their functionally efficient control by means of clear-text operator/computer dialogue and instantly available status information were other no less important design criteria. The general layouts of both systems and their major components are described. Within 1979, prototypes of both systems will be tested in practical operation by the principal West German broadcasting stations.
Isolation of genomic DNA from defatted oil seed residue of rapeseed (Brassica napus) (2011)

A simple protocol for obtaining pure, restrictable and amplifiable megabase genomic DNA from oil-free seed residue of Brassica napus, an important oil seed plant, has been developed. Oil from the dry seeds was completely recovered in an organic solvent and quantified gravimetrically followed by processing of the residual biomass (defatted seed residue) for genomic DNA isolation. The isolated DNA can be cut by a range of restriction enzymes. The method enables simultaneous isolation and recovery of lipids and genomic DNA from the same test sample, thus allowing two independent analyses from a single sample. Multiple micro-scale oil extraction from the commercial seeds gave approximately 39% oil, which is close to the usual oil recovery from standard oil seed. Most of the amplified fragments were scored in the range of 2.5 to 0.5 kb, best suited for scoring as molecular diagnostics.

Design of terrain adaptive versatile crawler vehicle HELIOS-VI (2002)

We are developing the "HELIOS" series, platforms for off-road vehicles and powered wheelchairs that are able to ascend and descend stairs. At present, we are developing an endless rotation locomotion type terrain adaptive vehicle "HELIOS-VI" that is propelled by 2 crawler belts. This vehicle has two continuously variable transmissions to change the velocity and direction of locomotion. The vehicle also has two active arms attached to the axis of the one drive pulley of the active crawler. One of the arms has two passive tires installed at its tip, and improves the vehicle's terrain adaptability in rough terrain; the other arm carries payload and adjusts payload posture. We introduced a structure that can change the posture of this load dynamically. This paper first outlines development process of the HELIOS series, and then discusses the configuration of terrain adaptive crawler vehicle HELIOS-VI and the design of its driving mechanism.
Customizable detection of changes for XML documents using XPath expressions (2006)

Change detection in XML documents is an important task in the context of query systems. In this paper, we present CustX- Diff, a customizable change detection approach for XML documents based on X-Diff [6]. CustX-Diff performs the change detection operation simultaneosly with the XPath based filtering of XML document parts. The class of XPath expressions used is the tree patterns subset of XPath. For the embedding of simple paths into XPath expressions during the difference operation, a dynamic programming approach is proposed. Comparative performance results with respect to the original X-Diff [6] approach demonstrate the efficiency of the proposed method.
Mesenchymal Stem Cells Differentiate into an Endothelial Phenotype, Reduce Neointimal Formation, and Enhance Endothelial Function in a Rat Vein Grafting Model (2008)

Autologous vein grafts is still commonly used for arterial reconstructive procedures. Their success is limited by the development of neointimal hyperplasia. Clinical and experimental evidence suggest that the bone marrow derived mesenchymal stem cells (MSCs) participate in the neovascularization. The current study used a direct approach to test the hypothesis that, after vein grafting in a rat model, MSCs have potential effects on reendothelialization and neointimal formation. MSCs were isolated by bone marrow cell adherence. Autologously interpositioning left external jugular vein (LEJV) to left common carotid artery-induced vein grafting model of r at w as utilized. Vascular lesion formation after transplantation of MSCs labeled with 4',6-diamidino-2-phenylindole (DAPI) was investigated. Two weeks after implantation, immunofluorescence studies revealed that engrafted cells acquired an endothelial phenotype, and some expressed endothelial nitric oxide synthase (eNOS). Furthermore, proliferation of cells and neointimal formation decreased significantly after MSC implantation. Real-time reverse transcription-PCR and western blotting analysis showed a rise of eNOS expression in the MSC group compared with the vein grafting group. Therefore, engrafted MSCs appeared to differentiate into endothelial cells, diminish the neointima formation and contribute to the improvement on endothelial function, which indicates that MSCs may exert an important function as repair mechanism in vascular injury after vein grafting.
Active Clamping Circuit to Suppress Switching Stress on a MOS-Gate-Structure-Based Power Semiconductor for Pulsed-Power Applications (2011)

Metal-oxide-silicon (MOS)-gate-structure-based power semiconductors, such as MOS field-effect transistors, insulated-gate bipolar transistors, and MOS controlled thyristors, are widely used as high-voltage switch and power modulator components in pulsed-power applications. The power semiconductors are generally connected in series and in parallel in order to increase their maximum switching voltage and current, respectively. It is important to suppress overvoltage or switching stress on power semiconductors connected in series and parallel during an extremely short switching time and at fast operating frequency. Generally, gate drive control techniques and methods for the suppression of high voltage are required. To suppress overvoltage and switching stress, this paper proposes a simple and effective active clamping method rather than the use of a snubber circuit with free switching condition modulation. Based on comparative switching experiments, the active clamping method is expected to suppress switching stress and overvoltage while load and switching conditions are changed without modification of the high-side auxiliary circuit for pulsed-power applications.
Morphogenetic and Regulatory Mechanisms During Developmental Chondrogenesis: New Paradigms for Cartilage Tissue Engineering (2008)

Cartilage is the first skeletal tissue to be formed during embryogenesis leading to the creation of all mature cartilages and bones, with the exception of the flat bones in the skull. Therefore, errors occurring during the process of chondrogenesis, the formation of cartilage, often lead to severe skeletal malformations such as dysplasias. There are hundreds of skeletal dysplasias, and the molecular genetic etiology of some remains more elusive than of others. Many efforts have aimed at understanding the morphogenetic event of chondrogenesis in normal individuals, of which the main morphogenetic and regulatory mechanisms will be reviewed here. For instance, many signaling molecules that guide chondrogenesis--for example, transforming growth factor-beta, bone morphogenetic proteins, fibroblast growth factors, and Wnts, as well as transcriptional regulators such as the Sox family--have already been identified. Moreover, extracellular matrix components also play an important role in this developmental event, as evidenced by the promotion of the chondrogenic potential of chondroprogenitor cells caused by collagen II and proteoglycans like versican. The growing evidence of the elements that control chondrogenesis and the increasing number of different sources of progenitor cells will, hopefully, help to create tissue engineering platforms that could overcome many developmental or degenerative diseases associated with cartilage defects.
A 480mW 2.6GS/s 10b 65nm CMOS time-interleaved ADC with 48.5dB SNDR up to Nyquist (2011)

Trends in cable TV reception for data and video require simultaneous capture of many channels, e.g., 16, arbitrary located in the 48-to-1002MHz TV band. The challenges of integrating more than two zero-IF tuners on a single die could be simplified with a low-power 10b ADC that can digitize the entire TV band and be suitable for integration with baseband DSP. This work presents a 64χ inter leaved 2.6GS/S 10b 65nm CMOS ADC with on-chip calibrations, combining interleaving hierarchy with an open-loop buffer array operated in feedforward sampling and feedback-SAR mode. The ADC achieves an SNDR of 48.5dB at Nyquist and consumes only 0.48W.
