Partial hydrogenation of polyunsaturated fatty materials (1984)

Abstract For many applications involving the use of polyunsaturated triglycerides such as soybean oil, a liquid product having an improved stability to oxidation is required. The partial hydrogenation of soybean oil into a liquid product containing less oxidizable materials can be achieved with selective nickel catalysts. A soybean oil containing ca. 5% solid matter at 10 C, 1% linolenic acid and 0.5% conjugated dienes is obtained with a nickel/titanium oxide catalyst or with nickel‐zirconium oxide/kieselguhr catalyst treated wity fatty amines such as lauric or coco primary amines. In the frame of this work, ca. 100 heterogenous Ni catalysts have been tested under standard operating conditions for the partial hydrogenation of soybean oil.
Mechanics of the Aorta in Vivo (1971)

The hydraulic properties of the unexposed thoracic aorta were studied in five cats by angiography. Repeated measurements of pressure and diameter were obtained at various distances from the aortic root, and it became obvious that the unexposed aorta in cats was more than twice as distensible as the exposed aorta. Diameter of the aortic root, for example, varied by about 20% over a physiologic pulse pressure (40 mm Hg); even in the lower thoracic aorta variations exceeded 15%. When plotted as a function of distance from the root, aortic diameter and distensibility both decreased, and the calculated impedance increased. Despite these changes, however, the calculated reflection coefficients were quite small. It was concluded that geometric and elastic inhomogeneities in the thoracic aorta tend to balance one another, keeping the reflection coefficient quite low and helping to "decouple" the oscillatory left ventricular pump from the static peripheral vasculature. Since the aortic pulse contour is reflection-free during the first 50 msec following the onset of ventricular ejection, it may reliably indicate left ventricular properties and their changes with stress. In several animals, norepinephrine infusion was used to elevate the aortic pressure to hypertensive levels. When compared to hypertension induced by carotid reflex stimulation or mechanical occlusion of the aorta, however, aortic wall properties were essentially the same, suggesting that this agent has no important direct effect on the aortic wall.
Coupling sensing hardware with data interrogation software for structural health monitoring (2005)

Abstract. The process of implementing a damage detection strategy for aerospace, civil and mechanical engineering infrastructure is referred to as structural health monitoring (SHM). The authors ’ approach is to address the SHM problem in the context of a statistical pattern recognition paradigm. In this paradigm, the process can be broken down into four parts: (1) Operational Evaluation, (2) Data Acquisition and Cleansing, (3) Feature Extraction and Data Compression, and (4) Statistical Model Development for Feature Discrimination. These processes must be implemented through hardware or software and, in general, some combination of these two approaches will be used. This paper will discuss each portion of the SHM process with particular emphasis on the coupling of a general purpose data interrogation software package for structural health monitoring (DIAMOND II) with a modular wireless sensing and processing platform that is being jointly developed with Motorola Labs. More specifically, this paper will address the need to take an integrated hardware/software approach to developing SHM solutions..
Conspicuous consumption and the positional economy: policy and prescription since 1970 (2000)

Abstract In more recent years, the social significance of consumption has increased to such an extent that activity in the so‐called ‘positional economy’ is now seen to threaten prospects for sustainable, long‐term economic growth. In particular, the demand for status goods, fuelled by conspicuous consumption, has diverted many resources away from investment in the manufacture of more material goods and services in order to satisfy consumer preoccupations with their relative social standing and prestige. This paper looks at the policies and prescriptions which have been proposed in order to reduce levels of ‘conspicuous waste’ in the positional sector, and to redirect resources back into more productive economic activity.

Automatic VLSI Layout Verification (1981)

Xerox has instituted a set of software tools that close the loop between circuit design and mask generation of VLSI and provide checks and analysis along the way. The software includes circuit extraction, capacitance calaulation, nodal analysis and logic recognition as well as interfaces to graphic systems. The systematic method of capturing circuit designs and the software packages for analyzing mask data are described in this paper. The kinds of errors checked and the method of reporting errors are explained. This paper traces a single design from circuit description to mask making. It shows all the check points and verification tools presently available to a designer at Xerox. The example used for demonstration is the design of a small component of a chip called a cell. It should be pointed out that the tools described are not restricted to cell verification. For the most part they will accommodate up to full chip designs.
X-ray bandwidth: Determination by on-edge absorption and effect on various absorption experiments (2004)

Knowledge of the monochromaticity of an x-ray source is increasingly important in fundamental experiments and critical applications. The bandwidth of an x-ray beam, selected from a synchrotron radiation spectrum for example, ultimately defines the limiting resolution of the synchrotron source. The development of x-ray technology through the use of characteristic line sources of fixed line shape has impaired the development of understanding of this parameter. The bandwidth is particularly relevant with the modern trend towards the use of synchrotron sources in conjunction with monochromating devices, where the monochromaticity of the x-ray beam is not known a priori. The ability to control the bandwidth of the beam can lead to significant new experiments. We have observed the effect of the x-ray bandwidth on precise but relatively scaled measurements of the mass attenuation coefficient of molybdenum made on the absorption edge. We derive an expression describing the effect of the x-ray bandwidth on these measurements and invert this to determine the bandwidth of a highly monochromatized $20\ensuremath{-}\mathrm{keV}$ synchrotron x-ray beam to be $1.57\mathrm{eV}\ifmmode\pm\else\textpm\fi{}0.03\mathrm{eV}.$ The technique presented here determines the bandwidth, a parameter critically dependent on the x-ray optical elements in the beam, in such a manner as to require no knowledge of these elements. We demonstrate that the x-ray bandwidth has significant effects upon measured edge energies, mass attenuation coefficients, x-ray anomalous-fine structure and x-ray absorption near-edge structure (XANES). In particular, the observed x-ray bandwidth necessitates a correction of up to $1.4%$ in the measurement of the mass attenuation coefficient of molybdenum on the absorption edge and is shown to shift the observed absorption-edge energy location by up to $0.5\mathrm{eV}.$

The secure application of wireless sensor networks has become a hot technology. This paper mainly expounds the key management schemes of wireless sensor networks, and analyzes the mainstream key management schemes.
Adaptive linear prediction of autoregressive models in the presence of noise (2002)

An alternative algorithm is developed for adaptive linear prediction of autoregressive (AR) models in the presence of noise. Central to this algorithm is that the variance of the corrupting noise, which determine the bias in the standard least-squares (LS) parameter estimator, is estimated by using the expected LS errors under the assumption of the known ratio between the driving noise variance and the corrupting noise variance. Then the adaptive linear prediction (ALP) algorithm is established via the bias correction principle. While achieving estimation unbiasedness, the proposed ALP algorithm exhibits computational and algorithmic advantages over the previously developed LS based algorithms.

A Seismic Reconnaissance in the Mcmurdo Sound Region, Antarctica (1966)

Abstract A portable first-arrival seismic refraction instrument was used to measure seismic P-wave velocities in ice, frozen ground, till and shattered rock at various places in the McMurdo Sound region, Antarctica. It was found that some frozen ground exhibits the same seismic velocity as ice, so that buried ice cannot be idengified by seismic velocity measurements. The depth of exfoliation of a granite outcrop in Taylor Valley was successfully measured, as was the depth of an ice-free moraine in Wright Valley. From this latter depth, and from reasonable assumptions about the diffusion of water vapour through till, a minimum age of 75,000 yr. has been deduced for the moraine. This age implies that no through-glacier occupied Wright Valley during the last Northern Hemisphere glaciation.
DER AUTARKE HYBRID - EIN UNIVERSELLES ANTRIEBSKONZEPT FUER PKW (1994)

Die Kombination zweier Antriebsquellen (Hybridantrieb mit konventionellem Verbrennungsmotor und kleiner Elektromaschine) mit weitgespreiztem stufenlosen Getriebe ermoeglicht deutliche Verbrauchsreduzierungen sowohl bei konstanten Leistungsanforderungen als auch im ECE-Zyklus. Die Kraftstoffeinsparung des Autarken Hybrids wird zum einen durch die Vermeidung des unguenstigen Teillastbetriebs des Verbrennungsmotors mit hohem spezifischem Verbrauch und zum anderen durch die Reduzierung und optimale Anpassung der Motordrehzahl im Langstreckenbetrieb erreicht. Der Beitrag stellt die Konzeption des Autarken Hybrids dar. Wesentliche Kennzeichen sind: Antrieb durch Verbrennungsmotor und E-Maschine mit gemeinsamem, stufenlosem Getriebe, E-Maschine ist direkt an Verbrennungsmotor koppelbar, moegliche Addition beider Antriebsquellen, Batterie muss nicht aus dem Stromnetz geladen werden, Bremsenergie-Nutzung.

Quantitative Analysis of DNA Content and Morphology of Colorectal Carcinoma (2002)

Objective To understand the biological behavior of colorectal cancer and its clinical value. Methods Using flow cytometry and scanning microspectrophotometry, we determined the cellular DNA content, ploidy and cell cycle fraction in 88 patients with colorectal carcinoma and precance rous lesions, and in 83 cases with normal colonic nucosa. Also we compared the results with clinical pathological parameters and CEA levels. Results Normal colonic mucosa had the same DNA contents as normal diploid cells (2C), with a DNA index (DI) in rang of 1.00±0.10.MSP histogram was defined as type I. The cellular DNA content of precancerous lesions (adenoma, polyp) was lower than that of cancer ( P 0 01); While their cellular nuclear areas were not much different from those of cancers ( P 0.05). The aneuploidy of DNA was 68.68% in 83 cases of colorectal cancer, with DI1.10 0.90. Their cellular nuclear DNA contents correlated with nuclear areas (r=0.71,P0.01). As the clinicopathological classification of Dukes ascended, the incidence of aneuploidy became higher. Cell cycle analysis indicated that the DNA synthesis fraction (SPF) of diploidy carcinomas was between normal colonic mucosa and aneuploidy carcinomas. The CEA values in aneuploid tumors ( 12.85ng/ml ) were much higher than those of diploid tumors (7.82ng/ml) before operation(P0.05). The DNA index by FCM and modal values by MSP had strong correlation (r=0.73, P0.01), being 95% in aneuploidy tumor and 50% in diploidy tumors. Conclusion The detection of DNA content is beneficial to early discovery of colorectal cancer. The analysis of DNA ploid is in accordance with CEA in predicting the prognosis of colorectal cancer. FCM and MSP in combination can provide an approach to early diagnosis, prediction of prognosis and selection of appropriate therapeutic methods for colorectal cancer.
Automatic control of voltage instability by an expert system utilizing pattern recognition techniques (1991)

The authors describe a knowledge-based algorithm for automatic control of extreme disturbances that could lead to system voltage instability. The study results show that it could adapt for quite different types of disturbance-be it loss of lines or loss of generation-to sustain system voltage stability. A new methodology has been developed that utilises the pattern recognition method in the areas of reactive power control following a contingency. Based on this new methodology, the operators can be provided with a priority list for searching the best available control measures after each contingency. The consequence of each chosen control measure can be predicted beforehand. The algorithm makes use of the knowledge about the system, sensitive factors, operating rules, operator's experience and other requirements for good system operation.
Glycosaminoglycans modulate inflammation and apoptosis in LPS‐treated chondrocytes (2008)

Previous studies reported that hyaluronic acid (HA), chondroitin sulphate (CS) and heparan sulphate (HS) were able to reduce the inflammatory process in a variety of cell types after lipopolysaccharide (LPS) stimulation. The aim of this study was to investigate the anti-inflammatory effect of glycosaminoglycans (GAGs) in mouse articular chondrocytes stimulated with LPS. Chondrocyte treatment with LPS (50 microg/ml) generated high levels of TNF-alpha, IL-1beta, IL-6, IFN-gamma, MMP-1, MMP-13, iNOS gene expression and their related proteins, increased NO concentrations (evaluated in terms of nitrites formation), NF-kappaB activation and IkBalpha degradation as well as apoptosis evaluated by the increase in caspase-3 expression and the amount of its related protein. The treatment of chondrocytes using two different doses (0.5 and 1.0 mg/ml) of HA, chondroitin-4-sulphate (C4S), chondroitin-6-sulphate (C6S), HS, keratan sulphate (KS) and dermatan sulphate (DS) produced a number of effects. HA exerted a very small anti-inflammatory and anti-apoptotic effect while it significantly reduced NO levels, although the effect on iNOS expression and activity was extremely slight. C4S and C6S reduced inflammation mediators and the apoptotic process. C6S failed to decrease NO production, although iNOS expression and activity were significantly reduced. HS, like C4S, was able to reduce all the effects stimulated by LPS treatment. KS and DS produced no reduction in any of the parameters considered. These results give further support to the hypothesis that GAGs actively participate in the regulation of inflammatory and apoptotic processes.

Klippel‐Trenaunay‐Weber syndrome associated with a 5:11 balanced translocation (1995)

We report on a case of Klippel-Trenaunay Weber syndrome (KTWS) associated with a reciprocal translocation [46,XX,t (5;11) (q13.3;p15.1)]. The patient has developmental delay and minor anomalies in addition to classic findings of KTWS. These data support the notion that Klippel-Trenaunay-Weber syndrome may be due to a single gene defect and suggests the possible localization of a Klippel-Trenaunay-Weber gene(s) to 5q or 11p.

Specification of FMS real-time control based on Petri nets with objects and process failure monitoring (2002)

This paper presents an approach for control and monitoring of discrete events systems. We show how it is possible to preserve the advantages of a hierarchical control structure for process monitoring purposes. The limitations of the monitoring system induced by the tools classically used for the specification of the control sequences are exposed. A new approach of knowledge representation is proposed: a database model is associated to the hierarchical control and monitoring structure. In this context, the main monitoring functions become more powerful and are able to treat most of the erroneous situations following from a process failure.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Identification of enteric pathogens by heat shock protein 60 kDa (HSP60) gene sequences (2002)

A highly specific and reproducible approach for the simultaneous detection of enteric pathogenic bacteria was developed using bacterial hsp60 gene and molecular biological tools. A single pair of universal primers was derived from the highly conserved sequence of hsp60 genes encompassing a 600-bp hypervariable region. PCR amplification followed by either dot blot hybridization or restriction enzyme digestion performed on 38 enteric bacteria indicated that this approach could differentiate not only different genera such as Campylobacter, Yersinia and Vibrio, but also species that are closely related genetically, such as between C. jejuni and C. coli, or between Salmonella and Shigella or Escherichia coli.
Control mechanisms of Carboniferous brachiopod zones in eastern Australia (1981)

Analysis of the Carboniferous brachiopod zones of eastern Australia shows that they were affected by two major controlling factors ‐ eustatic changes of sea level, and a deterioration (cooling) of climate. Eustatic lowering of sea level caused the removal of the sea from narrow shelf areas and a loss of habitat, and was responsible for the first (late early to middle Visean) of two major episodes of faunal extinction. Subsequent transgression restored a modified warm‐water cosmopolitan fauna to the shelf regions. Smaller changes in sea levels were probably responsible for the abrupt disappearance of many species or genera at zonal boundaries and their replacement by a new set of species and genera in succeeding zones. The second major episode of extinction was caused by the lowering of temperature in the latest Visean to early Namurian because of the rapid southerly movement of Australia. The warm water cosmopolitan fauna was eliminated and replaced by the low‐diversity Gondwana fauna. Both mechanisms produced particular faunal signatures. The diversity of faunas on either side of the hiatus produced by eustatic lowering of sea level is constant in areas with uniform climatic conditions, and in warm to temperate regions there are low levels of endemism. Faunas associated with a sudden lowering of temperature suffer a significant drop in diversity but are characterized by a high level of endemism.
ZAP-70 Expression in B-Cell Hematologic Malignancy Is Not Limited to CLL/SLL (2004)

ZAP-70 is a tyrosine kinase expressed in normal T cells and NK cells. Expression of ZAP-70 has been associated with poor prognosis in B-cell chronic lymphocytic leukemia and might be a surrogate marker for immunoglobulin heavy chain (IGH) mutational status in that disease. Little is known about ZAP-70 expression in other hematologic malignant neoplasms. We examined 446 specimens representing a range of hematopoietic malignant neoplasms for ZAP-70 expression by immunohistochemical analysis. As expected, most T cell–lineage disorders and a subset of small lymphocytic lymphomas were positive. IGH mutational status corresponded to ZAP-70 expression in a small subset of small lymphocytic lymphoma cases subjected to sequence analysis. Of note, however, ZAP-70 was expressed in a minority of other types of B-cell lymphomas, including precursor B-cell acute lymphoblastic leukemia, diffuse large B-cell lymphoma, mantle cell lymphoma, and very rare cases of classic Hodgkin lymphoma. Immunohistochemical analysis represents an alternative method for assessing ZAP-70 expression and reveals that other B-cell malignant neoplasms express ZAP-70.
