Matching and Clustering: two Steps towards Automatic Object Model Generation in Computer Vision (1993)

In this paper, we present a general framework for a system for automatic model generation and recognition of 3D polyhedral objects. Such a system has many applications ill robotics: recognition, localization, grasping... Here we focus upon one question: from multiple images of one 3D object taken from different unknown viewpoints, how to recognize those which represent identical aspects of tile object? Briefly, is it possible Io (leternline automatically if two images are similar or not? The two stages detailed ill this paper are matching of two images and clustering of a set of images. Matching consists of finding the common features of two images while no information is known about the image content, camera motion or calibration. Clustering consists of regrouping into sets tile images representing identical aspects of the objects. For both stages, experimental results on real images are shown.
Precision measurements of the thermal conductivity, electrical resistivity, and Seebeck coefficient from 80 to 400 K and their application to pure molybdenum (1974)

A longitudinal heat-flow technique for precise measurement of thermal conductivity, electrical resistivity, and Seebeck coefficient over the temperature range from 80 to 400 K is described. The basis of the technique is the use of a calibrated platinum resistance thermometer to provide in situ calibrations of specimen thermocouples. The total determinate errors at 273 K are ± 0.23% for electrical resistivity, ± 0.49% for thermal conductivity, and ± 0.07 μV/K for the Seebeck coefficient when Pt wire is used as the reference. Experimental results on two high-purity molybdenum specimens with cross-sectional areas differing by a factor of four are presented to demonstrate the system precision and low level of indeterminate erros.
Feminism and the situation of women today (1999)

As we enter a new millennium, many women throughout the world are campaigning, organising and working together to improve their lives. Their aims, methods and interests are diverse in the extreme. Some are working in women's refuges, others are establishing professional networks; some are campaigning against pornography, others are developing erotic writings for women; some are setting up women-only organisations, others are being elected into political office; some are demanding total legal equality with men, others want improved maternity leave; some are setting up literacy schemes for women, others are exposing the male bias of dominant forms of knowledge; some are campaigning for abortion on demand, others are insisting on the right of disabled women to have children. The list goes on.
Chemoselective Protection of the Amino Groups of Chitosan by Controlled Phthaloylation:  Facile Preparation of a Precursor Useful for Chemical Modifications (2001)

A simple and convenient procedure for chemoselectively protecting the amino groups of chitosan has been developed to provide N-phthaloyl-chitosan that is indispensable as a soluble N-protected precursor for further controlled modification reactions of chitosan. Although the conventional N-phthaloylation of chitosan in N,N-dimethylformamide was accompanied by partial phthaloylation of the hydroxy groups, the addition of a small amount of hydroxy-containing compounds effectively suppressed the O-phthaloylation. Of some compounds examined, water proved particularly suitable, resulting in the formation of chemoselectively N-phthaloylated chitosan without any appreciable O-phthaloyl groups. The resulting N-phthaloyl-chitosan was found to be crystalline despite the presence of a bulky substituent. A solubility test indicated that N-phthaloyl-chitosan exhibited considerable affinity for organic solvents.
Energy production, intracellular amino acid pools, and protein synthesis in chronic renal disease. (1989)

Intracellular glycolytic regulating enzyme activities, pyruvate kinase (PK) and phosphofructokinase (PFK), adenylate kinase (AK), energy charge (Ech), free amino acids (ICAA), and protein synthesis (PS) were measured in polymorphonuclear leukocytes--used as a cell model--in 62 adults and 12 children with chronic renal failure, and 66 normal adults and 21 children as comparison controls. In normal subjects, children had significantly lower enzyme activities and cell amino acid levels but similar Ech and higher PS than adults. ICAA concentrations were significantly higher than plasma amino acid concentrations (PAA) in both groups, and the PAA were not correlated with, nor indicative of, the ICAA concentrations. The variance (R2) in PS could be largely accounted for by a combination ("set") of six ICAA, as determined by multivariate analysis. The sets differed in children vs adults, suggesting that different proteins were being synthesized. In the uremic patients, reduced PF, PFK, Ech, most ICAAs and PS were indicative of cellular malnutrition. For the uremic adults, the abnormalities in cell metabolism were modified by therapy--nondialyzed uremics being worst, CAPD patients best and approximately normal, and hemodialyzed intermediate. The uremic CAPD children had reduced, PK, PFK, AK, most ICAA, and PS. Ech was increased. Cellular malnutrition in children with chronic renal failure may contribute to their poor growth.
Immunoprecipitation of the interleukin‐2 receptor from Hodgkin's disease derived cell lines by monoclonal antibodies (1987)

The nature of Hodgkin and Reed-Sternberg (H-RS) cells and their normal counterpart remains a matter of controversy. Our recent investigations have suggested that H-RS-cells derive from certain activated lymphocytes of either B or T cell origin. In keeping with this concept, we were able to demonstrate that in the majority of cases of Hodgkin's disease the interleukin-2 receptor (IL2-R) was detectable on H-RS-cells by three monoclonal antibodies (anti-Tac, Tü69 and ACT-1) with the sensitive alkaline phosphatase anti-alkaline phosphatase (APAAP) tissue staining procedure. In extension of these studies, we precipitated IL2-R antigen from two established permanent cell lines (L540 and L591) derived from patients with Hodgkin's disease. Although these cell lines are different in nature, in that the L540 line shows rearrangement for the T cell receptor beta chain gene and the L591 line displays rearrangement for immunoglobulin genes (gamma heavy and lambda light chain), the antigen precipitated by monoclonal antibodies against IL2-R exhibited a molecular weight of approximately 53 kd on the L591 line and 58 kd on the L540 line. Thus, these data strongly support the view that the labelling of H-RS-cells in tissue sections for IL2-R was not merely due to cross-reactivities of the two anti-IL2-R antibodies with a determinant of an unrelated structure but represents true IL2-R molecules.

Recent literature data on the mechanisms responsible for oxidative stress at infectious diseases and methods of their correction are reviewed.
Functional Identification of an 8-Oxoguanine Specific Endonuclease from Thermotoga maritima (2005)

To date, no 8-oxoguanine-specific endonuclease-coding gene has been identified in Thermotoga maritima of the order Thermotogales, although its entire genome has been deciphered. However, the hypothetical protein Tm1821 from T. maritima, has a helix-hairpin-helix motif that is considered to be important for DNA binding and catalytic activity. Here, Tm1821 was overexpressed in Escherichia coli and purified using Ni-NTA affinity chromatography, protease digestion, and gel filtration. Tm1821 protein was found to efficiently cleave an oligonucleotide duplex containing 8-oxoguanine, but Tm1821 had little effect on other substrates containing modified bases. Moreover, Tm1821 strongly preferred DNA duplexes containing an 8-oxoguanine:C pair among oligonucleotide duplexes containing 8-oxoguanine paired with four different bases (A, C, G, or T). Furthermore, Tm1821 showed AP lyase activity and Schiff base formation with 8-oxoguanine in the presence of NaBH4, which suggests that it is a bifunctional DNA glycosylase. Tm1821 protein shares unique conserved amino acids and substrate specificity with an 8-oxoguanine DNA glycosylase from the hyperthermophilic archaeon. Thus, the DNA recognition and catalytic mechanisms of Tm1821 protein are likely to be similar to archaeal repair protein, although T. maritima is an eubacterium.
Re-Designing from Scratch and Defending Offset Wells: Case Study of a Six-Well Bakken Zipper Project, McKenzie County, ND (2017)

ABSTRACT Completion optimization in unconventional wells has been an industry goal since the earliest stages of horizontal development. Motivated by the desire for higher financial returns and fueled by the rise of both technology and big data, optimization efforts have become de rigueur. This paper describes an optimization project in which a legacy Bakken completion design was set aside to make way for a "blank slate" analysis. Addressed in this context are the optimization research challenges faced by smaller operators in the play. The resulting re-designed completion was applied on a recent six-well zipper frac in east-central McKenzie County yielding a production increase of 13.5% with a cost reduction of 3.6% compared to legacy completions. On the same zipper project, an active well defense strategy on existing producers offsetting the six-well pad was also employed. With the increase in development density across the Bakken play, well interference associated with fracturing treatments is becoming increasingly common. While such well interference, known as "frac hits", can produce a variety of effects, including some that are beneficial, they are generally considered to be undesirable. Included in this paper is a discussion of the operator's frac hit experience and the results of the active well defense strategies applied in this project.
X-ray powder diffraction study of Sn <sub>0.59</sub> Ti <sub>0.41</sub> Te <sub>3</sub> O <sub>8</sub> (2008)

The crystal structure of titanium-tin tellurium oxide Sn 0.59 Ti 0.41 Te 3 O 8 has been determined using X-ray powder diffraction techniques. At room temperature, the title compound crystallizes in cubic space group Ia -3, with lattice parameter a =11.05515(6) Å. Rietveld refinement of the structure led to final confidence factors R p =0.0395 and R wp =0.0577. The structure of Sn 0.59 Ti 0.41 Te 3 O 8 consists of isolated Ti/SnO 6 -octahedra slightly deformed in the a direction. The TeO 4 E [ E =lone pair of Te(IV) atoms] groups are located between the octahedra ensuring the stability of the structure by Ti/Sn-O-Te bonding contacts. Only one peak in thermal behavior was detected for this compound at 488 K by differential scanning calorimetry experiment. An IR spectroscopic study is employed as a means to obtain preliminary structural information and shows the presence of the Ti/SnO 6 and TeO 4 E groups. This result is later confirmed by X-ray diffraction studies.
Deterministic diffractive diffusers for displays (2001)

A LCD backlighting device that uses a diffractive light extractor has been developed for applications in which pointlike light sources are employed. The novel system eliminates the images of light sources, which appear as bright lines emanating from each source in the conventional diffractive approach. In addition, the system illuminates the LCD uniformly: Modulation of the diffractive structure as a function of position is used to control the output field of this extended planar light source.
Monitoring of Blood-<sup>10</sup>B Concentration for Boron Neutron Capture Therapy Using Prompt Gamma-Ray Analysis (1995)

The aim of the present study was to monitor the blood-10B concentration of laboratory dogs receiving boron neutron capture therapy, in order to obtain optimal agreement between prescribed and actual dose. A prompt gamma-ray analysis system was developed for this purpose at the High Flux Reactor in Petten. The technique was compared with inductively coupled plasma-atomic emission spectrometry and showed good agreement. A substantial variation in 10B clearance pattern after administration of borocaptate sodium was found between the different dogs. Consequently, the irradiation commencement was adjusted to the individually determined boron elimination curve. Mean blood-10B concentrations during irradiation of 25.8 +/- 2.2 micrograms/g (1 SD, n = 18) and 49.3 +/- 5.3 micrograms/g (1 SD, n = 17) were obtained for intended concentrations of 25 micrograms/g and 50 micrograms/g, respectively. These variations are a factor of two smaller than irradiations performed at a uniform post-infusion irradiation starting time. Such a careful blood-10B monitoring procedure is a prerequisite for accurately obtaining such steep dose-response curves as observed during the dog study.
The Potential of Trace Amines and Their Receptors for Treating Neurological and Psychiatric Diseases (2007)

Mining of the human genome has revealed approximately 7000 novel proteins, which could serve as potential targets for the development of novel therapeutics. Of these, approximately 2000 are predicted to be G-protein coupled receptors. Within this group of proteins, a family of 18 mammalian receptors has recently been identified that appear to exhibit selectivity toward the so-called trace amines. The trace amines are a family of endogenous compounds with strong structural similarity to classical monoamine neurotransmitters, consisting primarily of 2-phenylethylamine, m- and p-tyramine, tryptamine, m- and p-octopamine and the synephrines. The endogenous levels of these compounds are at least two orders of magnitude below those of neurotransmitters such as dopamine, noradrenaline and 5-HT. The effects of these low physiological concentrations have been difficult to demonstrate but it has been suggested that they may serve to maintain the neuronal activity of monoamine neurotransmitters within defined physiological limits. Such an effect of trace amines would make them ideal candidates for the development of novel therapeutics for a wide range of human disorders. Although the demonstration of a trace amine family of receptors has seen a resurgence of interest in these endogenous compounds, with recent articles reviewing trace amine pharmacological and physiological responses, the potential clinical utility of the trace amine receptors has not been specifically addressed. Historically, trace amines have been implicated in a diverse array of human pathologies ranging from schizophrenia to affective disorders to migraine. Recent studies have strengthened some of this historical data by linking trace amine receptor polymorphisms and mutations to distinct clinical conditions. The aim of the current article is to review the previous studies linking trace amines to human pathology in the context of the recently discovered trace amine receptors and evidence of the existence of trace amine receptor polymorphisms and mutations associated with such disorders. In addition, recent evidence linking trace amines to the development of drug dependence will be discussed.
Adaptive imaging spectrometer in a time-domain filtering architecturedaptive Imaging Spectrometer in a Time-Domain Filtering Architecture (2003)

We demonstrate an imaging spectrometer with 30nm resolution that utilizes a novel time-domain filtering architecture. The architecture is based on a pixel by pixel integration of the interferogram signal mixed with reference waveforms. The system can be adapted in real time to discriminate between LED sources of different wavelengths, perform signal processing on the spectra, as well as discriminate between highly overlapping, broadband spectral features in a scene illuminated by a tungsten lamp. Unlike a conventional spectral signature discrimination system, which needs a dedicated computation subsystem running a discrimination algorithm, the time-domain filtering architecture embeds much of the computation in the filtering, which will aid the design of integrated miniaturized spectral signature discrimination systems.
Analysis of Natural and Induced Variation in Tomato Glandular Trichome Flavonoids Identifies a Gene Not Present in the Reference Genome (2014)

Flavonoids are ubiquitous plant aromatic specialized metabolites found in a variety of cell types and organs. Methylated flavonoids are detected in secreting glandular trichomes of various Solanum species, including the cultivated tomato (Solanum lycopersicum). Inspection of the sequenced S. lycopersicum Heinz 1706 reference genome revealed a close homolog of Solanum habrochaites MOMT1 3'/5' myricetin O-methyltransferase gene, but this gene (Solyc06g083450) is missing the first exon, raising the question of whether cultivated tomato has a distinct 3' or 3'/5' O-methyltransferase. A combination of mining genome and cDNA sequences from wild tomato species and S. lycopersicum cultivar M82 led to the identification of Sl-MOMT4 as a 3' O-methyltransferase. In parallel, three independent ethyl methanesulfonate mutants in the S. lycopersicum cultivar M82 background were identified as having reduced amounts of di- and trimethylated myricetins and increased monomethylated myricetin. Consistent with the hypothesis that Sl-MOMT4 is a 3' O-methyltransferase gene, all three myricetin methylation defective mutants were found to have defects in MOMT4 sequence, transcript accumulation, or 3'-O-methyltransferase enzyme activity. Surprisingly, no MOMT4 sequence is found in the Heinz 1706 reference genome sequence, and this cultivar accumulates 3-methyl myricetin and is deficient in 3'-methyl myricetins, demonstrating variation in this gene among cultivated tomato varieties.
Capillary Gas Chromatography in Essential Oil Analysis (1987)

Capillary GC has strongly contributed to the development of essential oil science both from an industrial point of view (quality control, new sources of odoriferous compounds) and from a scientific point of view (phytochemistry, chemotaxonomy, biochemistry, etc). The reserve, however, is also true. Essential oil research has contributed to the present state of the art in capillary gas chromatography, e.g. the polar and sometimes thermolabile character of essential oil components has emphasized the need for more inert capillary columns and better sample introduction systems, selective polar phases have been developed, etc. Within 14 separate contributions of the book the following topics are discussed: general aspects of essential oil preparation and analysis, considerations on the selection of capillary columns for the analysis, microtechniques, headspace versus classical analysis, 'fingerprints', industrial quality control, retention indices, dual channel analysis, gas chromatography-mass spectroscopy coupling, examples of artefact formation, GC-FTIR analysis, multidimensional gas chromatography.
Biological cell assays on an electrokinetic microchip (2002)

A technique for single cell assay of non adherent cells is demonstrated by using microfabricated flow manifolds and video fluorescence microscopy. The kinetic cellular event of calcium flux release was determined in human lymphocytes. Transport, incubation and reactions on the microchip was accomplished using either electroosmotic or hydrodynamic pumping.
SiC rapid thermal carbonization of the (111)Si semiconductor-on-insulator structure and subsequent metalorganic chemical vapor deposition of GaN (1996)

Si (111) semiconductor-on-insulator (SOI) structures have been converted to SiC by carbonization of the thin (&lt;100 nm) Si layer using rapid thermal chemical vapor deposition with mixtures of propane and H2 at atmospheric pressure. Carbonization temperatures around 1225–1250 °C produced SiC films with optimum structural properties. X-ray diffraction (XRD) reveals a single SiC peak at 2θ=35.7° corresponding to the (111) reflection, with an uncorrected full width at half-maximum (FWHM) of ∼0.24°. Infrared spectroscopy of SiC SOI structures obtained under optimum carbonization conditions exhibited a sharp absorbtion peak produced by the Si–C bond at 795 cm−1, with FWHM=22–25 cm−1. Metalorganic chemical vapor deposition growth of GaN on the (111) SiC SOI was carried out with trimethylgallium and NH3 precursors at 1000 °C. XRD indicates highly oriented hexagonal GaN, with FWHM of the (0002) peak of ∼0.15°. The 300 °K photoluminescence (PL) spectrum of GaN films exhibits a strong near band-edge peak (at λp∼371 nm, with FWHM=100–150 meV) and weak yellow emission. Under low power excitation, the 370 nm PL emission from the GaN/SiC SOI structure displays an emission intensity ∼10× higher than that of equivalent GaN films grown on sapphire.

Nanoparticle Arrays on Surfaces Fabricated Using Anodic Alumina Films as Templates (2003)

Abstract High density nanoparticle arrays on surfaces have been created using a template‐assisted approach. Templates were produced by evaporating aluminum onto substrates and subsequently anodizing the aluminum to produce nanoporous alumina films. The resulting templates have a narrow distribution of pore sizes tunable from ∼ 25 to ∼ 70 nm. To demonstrate the flexibility of this approach for producing nanoparticle arrays on various substrates, templates have been fabricated on silicon oxide, silicon, and gold surfaces. In all cases, a final chemical etching step yielded pores that extended completely through the template to the underlying substrate. Because the templates remain in intimate contact with the substrate throughout processing, they may be used with either vacuum‐based or wet chemical deposition methods to direct the deposition of nanoparticles onto the underlying substrates. Here we have produced gold nanodot arrays using evaporation and gold nanorod arrays by electrodeposition. In each case, the diameter and height of the nanoparticles can be controlled using the confining dimensions of the templates, resulting in high density (∼ 10 10 cm –2 ) arrays of nanoparticles over large areas (> 1 cm 2 ).
On-line spectral estimation of nonstationary time series based on AR model parameter estimation and order selection with a forgetting factor (1995)

A new method for on-line spectral estimation of nonstationary time series via autoregressive (AR) model construction is proposed. The method consists of on-line parameter estimation based on the recursive least squares ladder estimation algorithm with a forgetting factor and on-line order determination based on AIC with some modifications. The effectiveness of the proposed method is demonstrated by computer simulation study and applying to the actual data of electroencephalogram (EEG).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
