Using root distribution of specific functions in signal recovery from nonuniform samples (1994)

This article presents a new procedure for the recovery of a signal from its nonuniform samples based on the root distribution of a given function; as an example, an orthonormal sampling expansion analogue to the Shannon expansion is shown to be useful in the recovery. We also extend the concept of a "bandlimited signal" to transformed domains other than the Fourier domain.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Synthesis of s-Alcohols via Liquid Phase Oxidation of n-Paraffins Effects of Ammoniac Base Co-catalysts (1992)

The present study indicated the liquid phase air oxidation of technical n-paraffins (C12C14), as a raw material, using dehydrated boric acids catalyst with an effective co-catalyst to give secondary alcohols with high selectivity.This catalyst system consists of dehydrated boric acids with a highly degree of dispersion property, and ammoniac base co-catalyst.This system prevents the inhibitory effect of aromatic compounds in n-paraffins on oxidation.Present boroxine (metaboric acid ester of alcohol) retards the auto-oxidation of n-paraffins, but the ammoniac base co-catalysts lessen this effect. Thus, we have been able to employ adequate dehydrated boric acids.The authors have thus devised a highly selective oxidation method of n-paraffins to secondary alcohols.Clarification of the ammoniac base co-catalyst should be further studied for catalysis mechanisms.
Imaging system at 94 GHz using tapered slot antenna elements (1983)

A 94 GHz Imaging System using linearly tapered slot antennas with integrated beamlead diodes as receptor elements has been developed. The elements have sufficient gain to directly illuminate the sub-reflector of a Cassegrain antenna. The one-foot diameter of the main reflector determines a beam-width of 0.7 degrees for each beam. The measured spacing between adjacent beams in a seven element array is 0.64 degrees. A four element array has also been used for tracking.

A silicon photomultiplier with &#x003E;30% detection efficiency from 450&#x2013;750nm and 11.6&#x03BC;m pitch NMOS-only pixel with 21.6% fill factor in 130nm CMOS (2012)

A 16×16 Silicon Photomultiplier (SiPM) is reported in a 130nm CMOS imaging technology with a photon detection probability of >;30% from 450-750nm. The SiPM demonstrates a 21.6% fill factor with an 11.6μm pitch and 8μm diameter SinglePhoton Avalanche Diodes (SPADs). This is achieved using a new SPAD structure with integrated resistor and capacitor. NMOS-only pixel electronics are used to improve fill factor and to implement an addressable array of SPADs that are isolated from the array and column load. A 1T DRAM in each pixel is implemented to inhibit the output of high dark count rate (DCR) SPADs. The SiPM also achieves: a median DCR of ≈200Hz at 1.2V excess bias; low after pulsing; and a SPAD timing jitter of ≈95ps at 654nm with a column delay of ≈100-200ps.
Involvement of membrane sugar receptors and membrane glycoconjugates in the adhesion of 3LL cell subpopulations to cultured pulmonary cells. (1986)

Lewis lung carcinoma cells are able to bind sugar residues, mainly alpha-D-glucosyl and alpha-D-mannosyl derivatives as assessed by fluorescent neoglycoproteins binding assay. We have investigated the binding efficiency and shown that: 3LL tumor cells are heterogeneous with regards to their capability to recognize neoglycoproteins, as shown by fluorescence microscopy and flow cytofluorometry analyses; basically two distinct subpopulations could be evidenced which were called glucose-receptor-rich (or glucose-specific lectin-rich, GLR 3LL) and glucose-receptor-poor (or glucose-specific lectin-poor, GLP 3LL) cells; those two subpopulations could be separated on the basis of their binding properties to neoglycoprotein-substituted microcarriers onto which GLR 3LL cells were able to rapidly adhere (2 h) while GLP 3LL cells were not. Some aspects of the biological behavior of these two selected populations were investigated in order to determine the possible involvement of 3LL cell membrane sugar receptors in cell-cell recognition and adhesion to other cells: namely C57 B1/6 mouse pulmonary cells maintained in primary culture. The two 3LL sublines bind to pulmonary cells but their adhesion kinetics were markedly different. Adhesion inhibition studies showed the adhesion process to be dependent upon the specificity of membrane lectins present on both the tumor cell surface (alpha-D-glucose-specific) and on the pulmonary cells (alpha-L-fucose-specific). Surface sugar-specific receptors on mouse pulmonary cells were shown to bind beta-D-galactose-, alpha-L-fucose and alpha-L-rhamnose substituted serum albumin. A neoglycoprotein bearing alpha-L-rhamnose residues was an efficient binder under the conditions of cell adhesion experiments and a potent cell adhesion inhibitor. A fucose-containing neoglycoprotein was shown to have a high inhibitory activity when used concomitantly to alpha-D-glucose-containing neoglycoproteins. Adhesion inhibition experiments, performed with cells the sugar specific receptors of which have been selectively inactivated, showed that the alpha-L-fucose specific receptors on pulmonary cell surface are partly responsible for the specificity of this cell-cell recognition process.

<i>vesl</i>, a gene encoding VASP/Ena family related protein, is upregulated during seizure, long‐term potentiation and synaptogenesis<sup>1</sup> (1997)

We have isolated a novel cDNA, vesl, that was induced during convulsive seizure in the rat hippocampus. The vesl gene encodes a protein of 186 amino acids that has significant homology to the EVH1 domain of the VASP/Ena family of proteins implicated in the control of microfilament dynamics. The expression of vesl mRNA was induced in the granule cell layer during persistent long-term potentiation (LTP) of the dentate gyrus in an NMDA receptor-dependent manner. Furthermore, vesl mRNA was expressed at a high level during hippocampal synaptogenesis. We suggest that the Vesl protein may be involved in the structural changes that occur at synapses during long-lasting neuronal plasticity and development.
Hydraulic distribution of water and air over a membrane module using AirFlush® (2002)

Delft University of Technology, Department of Sanitary Engineering, is researching the fundamentals of air-water flushing (AirFlush®) for membrane cleaning. The research is focused on two topics: velocities of water and air for optimal cleaning and the distribution of water and air over the cross sectional area of the module. In an earlier study the velocities of water and air to achieve an optimal cleaning for tubular membranes have been investigated. In this article the distribution of water and air over the cross sectional area of a 3ʺ-membrane module will be discussed. Experiments have been performed and the fundamental processes that influence the distribution of air and water have been studied.
Xanthine derivative HWA 138 attenuates hemodynamic and oxygen uptake dysfunction secondary to severe endotoxin shock in sheep. (1992)

Continuous E. coli endotoxin infusion in five awake sheep produced hypodynamic shock characterized by decreased cardiac output, increased pulmonary vascular resistance (PVR), leukopenia, high plasma levels of lactate, thromboxane B2 (TXB2) and 6-keto-prostaglandin F1 alpha (6-k-PGF1 alpha), and a pathological oxygen delivery-consumption relationship, i.e., a dependence of oxygen consumption on oxygen delivery, leading to death within 8-9 hr. Pretreatment with the xanthine derivative HWA 138 in six sheep prevented the endotoxin-induced fall in cardiac output and oxygen delivery, attenuated the increase in PVR and plasma 6-k-PGF1 alpha, and prolonged survival to 13-19 hr in five of the six sheep. The xanthine derivative had no effect on endotoxin-induced leukopenia, nor on the increase of plasma lactate and TXB2 levels. Although in the HWA 138 treated animals oxygen consumption increased significantly (by 59 +/- 17% at 8 hr), this increase was only transient, and at a level that was most probably insufficient to meet the increased metabolic requirements of this model. We conclude that pretreatment with HWA 138 attenuates endotoxin-induced hemodynamic and oxygen uptake disturbances and prolongs survival in this animal model of severe endotoxin shock.
Nonequilibrium Fluctuations and Mechanochemical Couplings of a Molecular Motor (2007)

We investigate theoretically the violations of Einstein and Onsager relations and the thermodynamic efficiency for a single processive motor operating far from equilibrium using an extension of the two-state model introduced by Kafri et al. [Biophys. J. 86, 3373 (2004)10.1529/biophysj.103.036152]. With the aid of the Fluctuation Theorem, we analyze the general features of these violations and this efficiency and link them to mechanochemical couplings of motors. In particular, an analysis of the experimental data of kinesin using our framework leads to interesting predictions that may serve as a guide for future experiments.
Vaginal deployment and tenofovir delivery by microbicide gels (2015)

Gels are one of the soft material platforms being evaluated to deliver topically acting anti-HIV drugs (microbicides) to the vaginal environment. For each drug, its loaded concentration, gel properties and applied volume, and frequency of dosing can be designed to optimize PK and, thence, PD. These factors also impact user sensory perceptions and acceptability. Deterministic compartmental modeling of vaginal deployment and drug delivery achieved by test gels can help delineate how multiple parameters characterizing drug, vehicle, vaginal environment, and dosing govern details of PK and PD and also gel leakage from the canal. Such microbicide delivery is a transport process combining convection, e.g., from gel spreading along the vaginal canal, with drug diffusion in multiple compartments, including gel, mucosal epithelium, and stroma. The present work builds upon prior models of gel coating flows and drug diffusion (without convection) in the vaginal environment. It combines and extends these initial approaches in several key ways, including: (1) linking convective drug transport due to gel spreading with drug diffusion and (2) accounting for natural variations in dimensions of the canal and the site of gel placement therein. Results are obtained for a leading microbicide drug, tenofovir, delivered by three prototype microbicide gels, with a range of rheological properties. The model includes phosphorylation of tenofovir to tenofovir diphosphate (which manifests reverse transcriptase activity in host cells), the stromal concentration distributions of which are related to reference prophylactic values against HIV. This yields a computed summary measure related to gel protection ("percent protected"). Analyses illustrate tradeoffs amongst gel properties, drug loading, volume and site of placement, and vaginal dimensions, in the time and space history of gel distribution and tenofovir transport to sites of its anti-HIV action and concentrations and potential prophylactic actions of tenofovir diphosphate therein.
Alkylative Cyclization of 1,6-Enynes in Water with an Amphiphilic Resin-Supported Palladium Catalyst (2006)

An alkylative cyclization of a 1,6-enyne with aryl halides was performed with an amphiphilic polystyrene-poly(ethylene glycol) (PS-PEG) resin supported phosphine-palladium complex in water under heterogeneous conditions to give benzylidenecyclohexenes in good to high yields, which proceeds via formation of a vinylpalladium intermediate and subsequent intramolecular Heck reaction. The polymeric palladium catalyst can be readily recovered and recycled.
III-V Multijunction Solar Cells—New Lattice-Matched Products And Development Of Upright Metamorphic 3J Cells (2011)

AZUR SPACE's current CPV product 3C40C is an advanced lattice‐matched In0.50Ga0.50P/In0.01Ga0.99As/Ge triple junction (3J) solar cell. Recently, efficiencies up to 41.2% (450–600×AM1.5d) have been confirmed for this 40%‐class product. This kind of solar cell structure has now reached its practical efficiency limit and went into production in 2010. AZUR offers customized cell structures, regarding size and grid design, as well as anti‐reflection coatings adapted to the individual CPV system. Integration grades from diced wafers up to assemblies, such as dense arrays, are available. Special features and production results for the 3C40C structure are presented in this work. In order to further push efficiencies beyond 42% AZUR has successfully transferred the upright metamorphic cell from Fraunhofer ISE and advances this concept now for production. First results on metamorphic 3J solar cells at AZUR SPACE and the actual potential of this concept will be discussed. A target efficiency of 42% seems to be realistic.

Human naive CD4 T cells produce interleukin‐4 at priming and acquire a Th2 phenotype upon repetitive stimulations in neutral conditions (1995)

The maturation of naive CD4 T cells into interleukin (IL)-4-producing effectors was shown to require the presence of IL-4 at priming, the cellular origin of which remains unclear. We demonstrate here that naive T cells themselves release IL-4 at very low levels that are nevertheless sufficient to promote their development into Th2-like cells. This conclusion is based on three observations: (1) highly purified human naive CD4 T cells, of neonatal or adult origin, develop into Th2 effectors upon repetitive cycles of stimulation with anti-CD3 monoclonal antibody (mAb) cross-linked to CD32-B7 transfected L fibroblasts followed by IL-2 expansion; (2) IL-4 protein is readily detectable in the concentrated supernatant fluids of priming cultures performed in the presence of anti-IL-4 receptor mAb; and (3) addition of anti-IL-4 or anti-IL-4 receptor mAb at priming markedly inhibits the acquisition of IL-4- and IL-5-producing capacity while enhancing that of interferon-gamma.
Intrapleural chemotherapy for effusion from metastatic breast carcinoma (1970)

Efficacy of thoracentesis with the instillation of nitrogen mustard or thio-TEPA for malignant pleural effusions due to metastatic mammary carcinoma is investigated. One hundred and thirty-eight patients were evaluated, of whom 93 were treated by aspiration or intercostal tube drainage of the effusion followed by instillation of a cytotoxic agent. The remaining 45 patients received similar intrapleural chemotherapy and subsequent systemic cytotoxic agents several months later. Thirty-eight (27.5%) of the total patients in this study demonstrated an objective response with an average duration of 8.8 months. Subjective improvement was observed in 73 (53%). Rate and duration of response to instillation of nitrogen mustard and thio-TEPA were similar. The use of a recently devised weighted intercostal tube with the same alkylating agents significantly improved the results.
A performance study of delta modulation systems for voiceband data signals (1980)

In this paper the performance of delta modulation (DM) systems have been studied by computer simulation when the input signal to the DM coder is a voiceband data signal. First, the parameter values of three DM systems, linear DM (LDM), constant factor DM (CFDM), and continuously variable slope DM (CVSD) has been optimized for 4800 bits/s differential phase shift keying (DPSK) signal. Then, the performance of the three DM systems have been studied for ideal and noisy channels. It has been found that the peak signal-to-quantization-noise ratio (SQNR) is nearly the same regardless of coding scheme used, but CFDM yields the widest dynamic range. In a noisy channel, however, CFDM is very sensitive to channel bit errors. Considering the overall performance, CVSD appears to be the best among the three DM systems studied. Also, the performances of DM's have been compared with those of PCM and DPCM systems. In addition, we have studied the effect of DM quantization noise on modem bit error rate by the Monte Carlo simulation method. It is possible to transmit a 4800 bits/s DPSK signal at a bit error rate below 10-5by CVSD with the rate of 32 kbits/s.
Stepwise Evolution Improves Identification of Diverse Peptides Binding to a Protein Target (2017)

Considerable efforts have been made to develop technologies for selection of peptidic molecules that act as substrates or binders to a protein of interest. Here we demonstrate the combination of rational peptide array library design, parallel screening and stepwise evolution, to discover novel peptide hotspots. These hotspots can be systematically evolved to create high-affinity, high-specificity binding peptides to a protein target in a reproducible and digitally controlled process. The method can be applied to synthesize both linear and cyclic peptides, as well as peptides composed of natural and non-natural amino acid analogs, thereby enabling screens in a much diverse chemical space. We apply this method to stepwise evolve peptide binders to streptavidin, a protein studied for over two decades and report novel peptides that mimic key interactions of biotin to streptavidin.
An evaluation of the osmotic method of controlling suction∗ (2008)

Experimental techniques of testing the mechanical properties of unsaturated soils are complex and difficult to conduct. As a consequence, complete sets of parameters that characterise the behaviour of unsaturated soils remain scarce and necessary. In this context, it has been found useful to gather the information obtained after some years of practice of the osmotic technique of controlling suction. As compared to the more documented axis-translation technique, the osmotic technique has its own advantages and drawbacks that are discussed in this paper, together with some potential future developments. The osmotic method has been developed by soil scientists in the 1960s and adapted to geotechnical testing in the early 1970s. This paper presents the osmotic technique and comments on its advantages (including suction condition close to reality and higher suctions easily attained) and drawbacks (including some concern with the membrane resistance and some membrane effects in the suction/concentration calibration). Various applications to geotechnical testing are presented such as the determination of the water retention curve, oedometer and triaxial testing procedures and the determination of the permeability of unsaturated soils. Recent developments, that include the extension of the method up to high suctions (10 MPa) are also described, together with some recent and novel applications such as data from high controlled suction oedometer compression test and the determination of the oil/water retention properties of oil reservoir chalks.
Quantitative measurements in an unsteady flame using high-speed rainbow schlieren deflectometry (2006)

Rainbow schlieren deflectometry was integrated with a high-speed digital imaging system to quantify the scalar flow structure of flames at a high temporal resolution. The schlieren image data were processed to determine the temperature field across the whole field assuming chemical equilibrium in the flame. First, shapes of steady hydrogen jet diffusion flames estimated from the schlieren technique were compared with those obtained by direct visualization. Next, the schlieren technique was applied to flame experiments at a jet exit Reynolds number of 300, which produced periodic oscillations or flame flicker. Rainbow schlieren images taken at acquisition rates of 30, 60, 125, 250, 500 and 1000 frames per second were analysed to construct the instantaneous temperature distributions across the whole field, the vortex convection velocity profiles, and the mean and root-mean-square temperature profiles. Results demonstrate that high-speed rainbow schlieren deflectometry is effective in quantitatively describing the transient flow structure of unsteady flames.

Determination of mass transfer coefficients for bubble‐free devolatilization of polymeric solutions in twin‐screw extruders (1985)

Abstract Theoretical and experimental studies have been conducted on the mass transfer rates which occur during the continuous devolatilization of bubble‐free polymeric solutions in a corotating twin‐screw extruder. Experimental measurements of the mass transfer rates, when reported in terms of the product of the individual liquid phase mass transfer coefficient and the surface area for mass transfer per unit volume of empty extruder, were found to correlate well with screw speed in accordance with the predictions of a model based on penetration theory. It is shown, however, that significant differences exist between the measured and predicted values for the rates of mass transfer, which leads to the conclusion that the surface area for mass transfer is substantially smaller than the value computed on the basis that continuous films are formed on the surfaces of the screws and the barrel wall.
