Ion exchanged polypyrrole‐based glucose biosensor: Enhanced loading and response (1995)

Abstract Enhanced loading of glucose oxidase in polypyrrole films via manipulation of the polymer morphology is reported. The exchange of bulky anions such as p ‐toluene sulfonate and ferricyanide present as dopant ions in polypyrrole, with chloride ion in solution leads to greater porosity and resultant maximization of glucose oxidase (GOx) immobilization in polypyrrole. The polypyrrole–Gox electrode thus prepared exhibits improved performance as an amperometric glucose sensor. The fractal dimension estimated from chronoamperometric data demonstrate the increased dimensionality of the polypyrrole network after ion exchange.
Dimension yields from short logs of low-quality hardwood trees. (1980)

Charts are presented for determining yields of 4/4 dimension cuttings from short hardwood logs of aspen, soft maple, black cherry, yellow-poplar, and black walnut for several cutting grades and bolt sizes. Cost comparisons of short log and standard grade mixes show sizes. Cost comparisons of short log and standard grade mixes show the estimated least expensive choice for specific cutting bill.
Discrete Chebyshev Classifiers (2014)

In large scale learning problems it is often easy to collect simple statistics of the data, but hard or impractical to store all the original data. A key question in this setting is how to construct classifiers based on such partial information. One traditional approach to the problem has been to use maximum entropy arguments to induce a complete distribution on variables from statis-tics. However, this approach essentially makes conditional independence assumptions about the distribution, and furthermore does not optimize prediction loss. Here we present a framework for discriminative learning given a set of statistics. Specifically, we address the case where all variables are discrete and we have access to various marginals. Our approach minimizes the worst case hinge loss in this case, which upper bounds the generalization error. We show that for certain sets of statistics the problem is tractable, and in the general case can be approximated using MAP LP relaxations. Empirical results show that the method is competitive with other approaches that use the same input. 1.
Serial changes in humoral and cellular immunity induced by prostaglandin E2 treatment of murine immune complex glomerulonephritis. (1985)

To examine the mechanism by which prostaglandin E2 (PGE2) inhibits the development of apoferritin (HAF)-induced immune complex glomerulonephritis (ICGN), weekly determinations of glomerular histologic conditions, blood urea nitrogen (BUN), total immunoglobulin levels, anti-HAF antibody, peripheral blood and splenic T cell subsets, and splenic suppressor cell activity were compared between mice receiving HAF and mice additionally treated with PGE2. PGE2 therapy prevented the development of glomerular hypercellularity and the increase in BUN concentration. Administration of PGE2 reduced anti-HAF IgG levels, but total IgM and IgG1, IgG2a, and IgG2b levels were unchanged. Mice receiving HAF alone demonstrated serial reductions in phenotypically identified peripheral blood pan-T cells and suppressor-cytotoxic T cells. PGE2-treated mice maintained normal levels of peripheral blood T cell subsets. Significant reductions in splenic total T cells and suppressor-cytotoxic cells occurred in mice receiving HAF as compared with normal mice. This reduction was offset by an increase in splenic B cells. PGE2 therapy prevented the decrease in splenic T cells at week 1, but not at week 4. Nonspecific suppressor cell activity, as measured by the ability of spleen cells from experimental mice to suppress a mixed lymphocyte reaction (MLR) or to suppress MLR-induced polyclonal IgG synthesis, was not different between the two groups. We conclude that prevention of HAF-ICGN by PGE2 is associated with a reduction in nephritogenic antibody production without an alteration in total immunoglobulin synthesis or the generation of nonspecific suppressor T cells. Changes in the percent of peripheral blood and splenic T cells and B cells may represent an effect of PGE2 on antigen-stimulated B cell proliferation.
Contribution of radon in natural gas to the natural radioactivity dose in homes (1973)

in these fields so as to control the tritium concentration and the tritium doses received by persons exposed to gas combustion products. The procedure used in calculating tritium doses received by persons exposed to stack emissions from a power plant burning the gas is outlined. A computer program is described that will compute the annual tritium dose received by any person living in the vicinity of such a power plant.
A Study of Robust Speech Recognition System and Its LSI Design (2005)

When a speech recognition system is used in real environment, noises cause a serious problem in the system. In this paper, we propose a method which normalizes feature parameters after filtering the time trajectories of both the power spectra and the log power spectra. As a result of the isolated word recognition experiment where fifteen kinds of noises were added, higher recognition rates was obtained than conventional method by Spectrum Subtraction (SS) and RelAtive SpecTrAl (RASTA). But the proposed method has problems such as processing time and groupe delay of FIR filter. This paper reports on the outline of LSI to solve these problems.
Beiträge zur Chemie des Bors, LXVI. Über die Bildung von Amin‐Addukten und Boroniumsalzen aus Methyl(methylthio)boranen (1974)

Abstract Pyridin (py) bildet mit den Methyl(methylthio)boranen (CH 3 ) 3−n B(SCH 3 ) n stabilere 1: 1‐Addukte als Timethylamin. Die Acidität der Borane sinkt mit steigender Zahl von CH 3 S‐Gruppen im Molekül. Mit CH 3 Cl 2 reagieren die Pyridin‐Addukte zu den Boroniumsalzen [(CH 3 ) 2 Bpy 2 ]Cl bzw. [CH 3 B(SCH 3 )py 2 ]Cl. Aus B(SCH 3 ) 3 , 2,2′‐Bipyridyl (bpy) und CH 2 Cl 2 wurde [(CH 3 S) 2 Bbpy]Cl erhalten. Die Bildung der Boroniumsalze wird diskutiert.
The adeno-associated virus type 2 p40 promoter requires a proximal Sp1 interaction and a p19 CArG-like element to facilitate Rep transactivation (1997)

We have identified the sequence elements that are required for adeno-associated virus type 2 p40 promoter activity. Mutation of specific promoter elements showed that two Sp1 sites at approximately -50 (Sp1-50) and -70 (GGT-70) bp upstream of the start of the p40 messages were necessary for maximal promoter activity. As expected, the TATA site at -30 was also essential. In vitro DNA binding experiments confirmed that the Sp1-50 and GGT-70 sites were bound by Sp1 or Sp1-like proteins. Two other transcription elements, the ATF-80 and AP1-40 sites, may play a role in p40 activity. Mutation of these elements resulted in a modest decrease in p40 transcription, but DNA binding experiments did not clearly demonstrate binding of transcription factors to these sites. In contrast, a major late transcription factor site at -110 was shown to bind the transcription factor, but mutation of this site had no effect on p40 activity. In a previous report, we have shown that transactivation of the p40 promoter by the viral Rep proteins required an upstream Rep binding element (in the terminal repeat or the p5 promoter), an unidentified p19 promoter element, and a p40 promoter element (D. J. Pereira and N. Muzyczka, J. Virol. 71:1747-1756, 1997). Here we demonstrate that the CArG-140 element in the p19 promoter and the Sp1-50 element in the p40 promoter are the specific p19 and p40 elements required for Rep induction of p40. As in the case of the p19 promoter, Sp1 facilitates interaction of Rep with the p40 promoter by interaction of the two proteins. Furthermore, electron microscopy experiments demonstrated that when Rep is bound to an upstream Rep binding element, it can interact with a proximal Sp1 site by protein contacts and create a loop in the intervening DNA. This finding suggests a common mechanism whereby the Rep binding element in the TR or the p5 promoter induces p19 and p40 activity by interaction with their respective Sp1 sites.
The Antiphospholipid-Thrombosis Syndromes:<i>Fact, Fiction, Confusion, and Controversy</i> (1993)

Anticardiolipin antibodies and the lupus anticoagulant are strongly associated with thrombosis and appear to be the most common of the acquired blood protein defects causing thrombosis. Although the precise mechanism(s) whereby antiphospholipid antibodies alter hemostasis to induce a hypercoagulable state remain unclear, several theories have been advanced. Because the aPTT is unreliable in patients with lupus anticoagulant and is not usually prolonged in patients with anticardiolipin antibodies, definitive tests, such as ELISA for IgG, IgA, and IgM anticardiolipin antibodies and the dRVVT (followed by cephalin correction for confirmation) for lupus anticoagulant, should be immediately ordered when suspecting antiphospholipid syndrome in persons with otherwise unexplained thrombotic or thromboembolic events or fetal wastage syndrome. The laboratory diagnosis of APL-T syndrome is summarized in Figure 1.
B cell dependence on and response to accessory signals in murine lupus strains. (1983)

B cell hyperactivity, a feature common to all lupus-prone murine strains, may be caused by hyperresponsiveness to, overproduction of, or bypassing of certain signals required for B cell activation, proliferation, and differentiation. In this study, we have compared the responses of B cells from three lupus-prone strains of mice (BXSB males, MRL and NZB/W females) and normal strains in a number of assays for which two or more signals are required to obtain a response. In medium to low density cultures of B cells from BXSB and NZB/W but not MRL/l lupus mice, the cells' proliferation induced by bacterial lipopolysaccharide (LPS) or anti-mu antibody was much higher than that of B cells from normal controls. At low B cell density, polyclonal activation by these substances and subsequent Ig secretion were dependent on accessory signals present in supernatants of concanavalin A-treated normal lymphocytes (CAS) or on the MRL/l proliferating T cell-derived B cell differentiation factor (L-BCDF) in both lupus-prone and immunologically normal mice. However, the responses of B cells from BXSB and NZB/W, but not MRL/l, mice to these accessory signals were higher than those of normal mice. Ig synthesis by fresh B cells of BXSB and NZB/W mice cultured in the absence of mitogens but in the presence of CAS or L-BCDF was higher than by similar cells from other strains, suggesting an increased frequency of B cells activated in vivo in these two autoimmune strains of mice. The patterns of IgG subclass secretion in response to LPS (without added CAS or L-BCDF) were abnormal in all lupus strains, with a predominance of IgG2b and/or IgG2a and low levels of IgG3, contrary to normal B cells for which IgG3 synthesis predominated. However, IgG1 synthesis in vitro by autoimmune and normal B cells alike was highly dependent on T cell-derived soluble mediators. Antigen-specific responses to SRBC in vitro of B cells from all lupus strains, like those of B cells from normal strains, required a minimum of three signals (antigen, LPS, T cell-derived antigen nonspecific helper factors). Yet, once triggered, B cells of BXSB and NZB/W mice gave higher responses than those of the other strains. We conclude that B cells of lupus mice have signal requirements similar to those of normal mice. Nevertheless, B cells of BXSB and NZB/W, but not MRL/l, lupus mice hyperrespond or process some accessory signals abnormally.

Anthocyanin Composition of Red Raspberry Juice: Influences of Cultivar, Processing, and Environmental Factors (1993)

ABSTRACT The anthocyanin and anthocyanidin pigment profiles of 46 authentic red raspberry juice samples were determined by HPLC. Total anthocyanin pigment content and percent polymeric color were also determined. This generated a database incorporating influences of cultivar, geographic origin, maturity, processing, and mold contamination. Cultivars exhibited characteristic patterns distinguished by quantitative rather than qualitative differences. Total pigment ranged from 4 to 1,102 mg/L. Commercial red raspberry juice concentrates (14) were also analyzed. Two were shown to be adulterated because of the presence of delphinidin glycosides. Three samples contained high amounts of polymerized pigments, indicating a history of processing or storage abuse.

Standoff detection and classification procedure for bioorganic compounds by hyperspectral laser-induced fluorescence (2015)

The high and still increasing number of attacks by hazardous bioorganic materials makes enormous demands on their detection. A very high detection sensitivity and differentiability are essential, as well as a rapid identification with low false alarm rates. One single technology can hardly achieve this. Point sensors can collect and identify materials, but finding an appropriate position is time consuming and involves several risks. Laser based standoff detection, however, can immediately provide information on propagation and compound type of a released hazardous material. The coupling of both methods may illustrate a solution to optimize the acquisition and detection of hazardous substances. At DLR Lampoldshausen, bioorganic substances are measured, based on laser induced fluorescence (LIF), and subsequently classified. In this work, a procedure is presented, which utilizes lots of information (time-dependent spectral data, local information) and predicts the presence of hazardous substances by statistical data analysis. For that purpose, studies are carried out on a free transmission range at a distance of 22m at two different excitation wavelengths alternating between 280nm and 355 nm. Time-dependent fluorescence spectra are recorded by a gated intensified CCD camera (iCCD). An automated signal processing allows fast and deterministic data collection and a direct subsequent classification of the detected substances. The variation of the substance parameters (physical state, concentration) is included within this method.
Reactive ion etching of Ta–silicide/polysilicon double layers for the fabrication of integrated circuits (1983)

Polysilicides currently find great interest as low resistivity gate and interconnect materials for integrated MOS circuits. We report on detailed investigations of the dry etching characteristics of Ta–silicide/n+-poly-Si double layers in fluorine and chlorine containing gases. A batch-type parallel plate reactor operated in RIE mode is used. We find a sensitive dependence of the etching results on various process parameters, such as gas mixtures, pressure, and rf power. Possible mechanisms for these findings are discussed. Anisotropic etching of the double layer has been achieved using a two stage process. In addition, we analyze the influence of the layer preparation technique on etching profiles.
LSE Re-Engineering Testbed (2009)

Abstract : The basic premise is that a legacy part design that was originally optimized for one manufacturing process may either be impossible to produce by another process, or too costly. To re-manufacture a replacement part, the original geometry and the material need to be modified; such modification must be done without violating the inter-facing, functional and structural constraints. The Rapid Re-Engineering System (RRES) is envisioned to serve as a bridge.
IGHV-unmutated and IGHV-mutated chronic lymphocytic leukemia cells produce activation-induced deaminase protein with a full range of biologic functions (2012)

Clonal evolution occurs during the course of chronic lymphocytic leukemia (CLL) and activation-induced deaminase (AID) could influence this process. However, this possibility has been questioned in CLL because the number of circulating AID mRNA(+) cells is exceedingly low; synthesis of AID protein by blood CLL cells has not been demonstrated; the full range of AID functions is lacking in unmutated CLL (U-CLL), and no prospective analysis linking AID expression and disease severity has been reported. The results of the present study show that circulating CLL cells and those within secondary lymphoid tissues can make AID mRNA and protein. This production is related to cell division because more AID mRNA was detected in recently divided cells and AID protein was limited to the dividing fraction and was up-regulated on induction of cell division. AID protein was functional because AID(+) dividing cells exhibited more double-stranded DNA breaks, IGH class switching, and new IGHV-D-J mutations. Each of these actions was documented in U-CLL and mutated CLL (M-CLL). Furthermore, AID protein was associated with worse patient outcome and adverse cytogenetics. We conclude that the production of fully functional AID protein by U-CLL and M-CLL cells could be involved in clonal evolution of the disease.
INTERACTION OF SIGNAL AND NOISE IN A NONLINEAR SYSTEM (1964)

Abstract : An experimental system has been constructed which simulates the detection stage of a receiver. With the application of periodic bursts of sine- wave plus Gaussian noise at the input, the output of this system is a non stationary random process. The addition of noise to the signal suppresses the mean at the output for the half-wave linear detector. However, the mean is unchanged for the half-wave square-law detector. The non-stationary variance is seen to vary between two values which can be easily measured. Output signal-to- noise ratio is greater for the half-wave square-law device than for the half- wave linear device. Addition of a clipper to the half-wave linear device decreases the signal-to-noise ratio. Detection characteristics of the half-wave linear and half-wave square-law devices are found to be equivalent and the clipper degrades the detection characteristic.

Effect of cyclosporin A on lymphopoiesis. II. Developmental defects of immature and mature thymocytes in fetal thymus organ cultures treated with cyclosporin A. (1989)

The effect of cyclosporin A (CsA) on early T cell development was studied by two-color flow cytometric and biochemical analyses using the fetal thymus organ culture system. Addition of CsA to organ culture resulted in a decreased cell yield and complete inhibition of the appearance of TCR-alpha beta-bearing, single positive thymocytes (both CD4+CD8- and CD4-CD8+). Furthermore, the generation of CD4+CD8+ thymocytes was markedly inhibited by CsA treatment, whereas the development of CD3-, CD4-CD8+ thymocytes and TCR-gamma delta-bearing, CD4-CD8- thymocytes was not affected. These results suggest that CsA induces a maturational arrest of T cells entirely within the thymic environment, and indicate that CsA-induced inhibition occurs at more than one stage of intrathymic T cell development.
Augmenting Entomopathogenic Nematodes in Soil from a Florida CitrusOrchard: Non-Target Effects of a Trophic Cascade. (2007)

Laboratory experiments were conducted to study non-target effects of augmenting entomopathogenic nematode (EPN)communities in soil. When raw soil from a citrus orchard was augmented with either 2,000 Steinernema riobrave or S. diaprepesi, fewer EPN (P </= 0.05) survived if the soil had also been treated with 2,000 S. riobrave 7 d earlier (i.e., two augmentation events rather than one). EPN survival was unaffected by treatment (P </= 0.05) in soil that was air-dried to disrupt antagonist activity prior to the experiment. When S. diaprepesi, S. riobrave, Heterorhabditis zealandica or no EPN were added to raw soil and S. diaprepesi was added 5 d later, the survival of both S. diaprepesi and of total EPN was greater (P </= 0.05) in soil that received no pretreatment than in soilpre treated with S. riobrave. Pretreatment of soil with H. zealandica or S. diaprepesi had less or no affect on survival of S. diaprepesi or total EPN. When nematodes were recovered from soil and placed on water agar, the number of S. diaprepesi that were killed by endoparasitic and trapping nematophagous fungi was greater (P </= 0.05) if soil was pretreated with steinernematid species than if the soil was not pretreated or was pretreated with H. zealandica. The adverse effects of pretreating soil on EPN survival were density dependent within a range of pretreatment dosages (20-100 IJ/cm(2) soil surface), and the treatment effects required more time to become evident at lower than at higher dosages. These experiments suggest that non-target effects of augmenting the EPN community in soil vary among EPN species and have the potential to temporarily reduce EPN numbers below the natural equilibrium density.
