Idiopathic Cold Urticaria: In Vitro Demonstration of Histamine Release upon Challenge of Skin Biopsies (1981)

WHEN patients with cold-induced urticaria are challenged with a cold stimulus, their exposed areas become pruritic, and hive formation and swelling are evident within a few minutes.1 Investigations regarding the pathogenesis of idiopathic cold urticaria have revealed a number of critical features of the reaction. In virtually all cases studied, histamine1 , 2 and other granule-associated chemotactic factors3 , 4 were released into the circulation when the patient was challenged by having one hand placed in ice water. The sensitivity to cold in some patients (10 per cent in our series) can be passively transferred,5 and this activity can be selectively removed with an . . .
Temperature-sensitive poliovirus mutant fails to cleave VP0 and accumulates provirions (1990)

A temperature-sensitive mutant of poliovirus, VP2-103, was isolated and characterized. A single nucleotide change, resulting in the substitution of glutamine for arginine at amino acid 76 of the capsid protein VP2, prevented the maturation of virions at the nonpermissive temperature. Particles indistinguishable from the previously elusive provirions were observed; these particles have been proposed to be penultimate in virion morphogenesis. Cleavage of VP0 into VP2 and VP4, the products found in mature virions, was not observed in VP2-103-infected cells at the nonpermissive temperature. The cleavage of VP0 in wild-type poliovirus-infected cells is dependent on RNA packaging; this reaction has been postulated to be autocatalytic. The existence of RNA-containing provirionlike particles in VP2-103-infected cells shows that RNA packaging can be uncoupled from VP0 cleavage.
Enhanced oxygen reduction activity of size-selected platinum subnanocluster catalysts: Pt<sub><i>n</i></sub> (<i>n</i> = 3–9) (2022)

Pt n subnanoclusters ( n = 3–9) on a carbon substrate exhibit 1.6–2.2 times higher activity than the standard Pt/C catalysts. EXAFS experiments and DFT calculations show plausible structures and energetics for reaction intermediates in the processes.
Using Education.al Television as a Delivery System for Teaching Futures Market Concepts (1976)

Thirteen weekly programs on futures markets were taught to farmers using television as a delivery system. Agricultural economists were responsible for technical accuracy, while professional writers and announcers were responsible for communicating ideas. Five thousand individuals pre-enrolled in the series. One third of the enrollees watched nine or more programs.
<i>GATA2</i> null mutation associated with incomplete penetrance in a family with Emberger syndrome (2017)

Incomplete penetrance may indicate that GATA2 haploinsufficiency is not enough to produce the phenotype of Emberger syndrome. It could be useful to perform whole exome or genome sequencing, in cases where incomplete penetrance or high variable expressivity is described, in order to probably identify specific gene interactions that drastically modify the phenotype. In addition, skewed gene expression by an epigenetic mechanism of gene regulation should also be considered.
The relationship between critical dimension shift and diffusion in negative chemically amplified resist systems (1991)

Reports of latent image instability in several positive acid catalyzed resists have stimulated interest in the image stability of advanced negative resists (ANR). The critical dimension stability of the chemically amplified ANR resist SAL603 with respect to delay time between the exposure and post-exposure bake (PEB) steps was determined. Both dense and isolated 1.0 μm features were stable during a 24 h delay period and delay times from 24 h to 48 h resulted in a decrease in linewidth. The method of loss in linewidth as a function of delay time was not due to diffusion of the acid within the film. The threshold crosslink density model was introduced based on several simple assumptions concerning the effect of crosslink density (Θ) on image formation and the relationship of the crosslink density to resist acid concentrations. A method was described whereby the threshold crosslink density model can be used to determine the relative crosslink density of the resist as a function of distance along the feature edge. An analysis of the relative values of crosslink density within the resist was used to show that acid loss and not diffusion was responsible for the change in resist linewidth as a function of delay time.
Dc and un SQUID's for readout of ac-biased transition-edge sensors (2003)

We have developed a set of SQUIDs optimized for readout of ac-biased transition edge sensors. Junction shunts are made of Pd and attached to cooling fins to facilitate low-noise operation at sub-kelvin temperatures. SQUID's have a low loop inductance in order to reach a large natural dynamic range even without negative feedback. The SQUIDs are intended to be used for frequency-domain multiplexing of X-ray calorimeter arrays. Both traditional dc-SQUIDs and novel un-SQUIDs are manufactured. The fabrication process and SQUID design criteria are reviewed.
Quantum Error Correction using Linear Optics (2005)

Beat-to-beat analysis method for magnetocardiographic recordings during interventions (2001)

Multichannel magnetocardiography (MCG) during exercise testing has been shown to detect myocardial ischaemia in patients with coronary artery disease. Previous studies on exercise MCG have focused on one or few time intervals during the recovery period and only a fragment of the data available has been utilized. We present a method for beat-to-beat analysis and parametrization of the MCG signal. The method can be used for studying and quantifying the changes induced in the MCG by interventions. We test the method with data recorded in bicycle exercise testing in healthy volunteers and patients with coronary artery disease. Information in all cardiac cycles recorded during the recovery period of exercise MCG testing is, for the first time, utilized in the signal analysis. Exercise-induced myocardial ischaemia was detected by heart rate adjustment of change in magnetic field map orientation. In addition to the ST segment, the T wave in the MCG was also found to provide information related to myocardial ischaemia. The method of analysis efficiently utilizes the spatial and temporal properties of multichannel MCG mapping, providing a new tool for detecting and quantifying fast phenomena during interventional MCG studies. The method can also be applied to an on-line analysis of MCG data.

ABSTRACT An overview of the various carbon structures with characteristic sizes in the nanoscale region is presented, with special attention devoted to the structures and properties of 'nanodiamond' and carbon nanotubes. The term 'nanodiamond' is used broadly for a variety of diamond-based materials at the nanoscale ranging from single diamond clusters to bulk nanocrystalline films. Only selected properties of carbon nanotubes are discussed, with an aim to summarize the most recent discoveries. Current and potential applications of carbon nanostructures are critically analyzed.
Spatial Variability of Anaerobic Processes and Wastewater pH in Force Mains (2016)

The present study focuses on anaerobic organic matter transformation processes in force mains for the purpose of improving existing sewer process models. Wastewater samples were obtained at 100 m intervals from a 1 km long pilot scale force main and measured for several wastewater parameters. Transformation rates for selected parameters were calculated and their spatial variability analyzed. In terms of electron transfer, fermentation was the most significant process, resulting in a net volatile fatty acid formation of 0.83 mmol/L. Sulfate reduction resulted in a production of 0.73 mmol/L of inorganic sulfide. Methanogenesis was negligable in all experiments despite an anaerobic residence time of more than 30 hours. As a result of the anaerobic processes, the wastewater pH decreased by approximately one pH unit, resulting in a corresponding increase in the fraction of molecular hydrogen sulfide. A significant spatial variablilty was observed for the average transformation rates of all parameters.
Preliminary Findings from Quantitative Gait Analyses o f RGO Users (2001)

What is an RGO? The Reciprocating Gait Orthosis (RGO) is a rehabilitation device that enables people with lower limb paralysis to walk with the aid of crutches or a walker (Figs. 1, 2). RGO’s prevent motion at the knee and the ankle, and limit motion of the hip to the sagittal plane. The hip joints of the RGO are mechanically linked so that extension of one hip joint forces flexion in the other, and vice versa.

A millimeter-wave cassegrain antenna using shaped beam waveguide feed (2000)

As a way to increase the efficiency of the focused beam-fed Cassegrain antenna with a large aperture for use at millimeter-wave frequencies, a method is proposed for shaping the surface of two focusing reflectors in the focused beam waveguide feed. The reflector surface shaping method is presented. Since the reflector is used at millimeter-wave frequencies, it is necessary to take into account the effect of the aberration caused by the deformation of the reflector surface on the radiation characteristics. Both the sub- and main reflectors have quadratic surfaces. The aberration in the main reflector due to self weight deformation can be corrected with the deformation of the subreflector in the homologic design. Hence, in order to validate the present beam shaping method, it is necessary to evaluate the effects of the aberration caused by the alignment error of each focusing reflector on the radiation characteristics. In this paper, a method of shaping the two focusing reflectors is applied to the new 10-m antennas for the millimeter-wave interferometer of Nobeyama National Observatory (model No. 6). The alignment errors in the parallel shift in three axis directions and the rotating motion about the axes are assumed, and the aberration and the gain degradation are quantitatively investigated when each focusing reflector is deformed. It is shown that the grain degradation is small in the range of realizable alignment errors and that the method of shaping the surfaces of two focusing reflectors is effective as a reflector shaping method for a millimeter-wave large-aperture antenna. © 2000 Scripta Technica, Electron Comm Jpn Pt 1, 84(4): 39–47, 2001

A Kinetic Study of The Hydrogen Evolution Reaction in Phosphoric Acid Solutions with Iron and Manganese Phosphatized Steel Cathodes (2014)

In this investigation a kinetic study of the HER was carried out employing a steel rotating disk with different aqueous solutions containing Phosphoric Acid (H3PO4) with or without metallic manganese (Mn) and Nitric Acid (HNO3). Furthermore, the HER was evaluated on iron and manganese phosphate coatings. Analyses of Tafel plots and the charge transfer coefficients, revealed one electrical potential zone where the monoatomic hydrogen can be recombined electrochemically to H2 as the rate determining step, with charge transfer coefficients similar to an activationless process (α→0). On the other hand, an increase in the concentration of H3PO4 promotes a higherexchange current for the HER. The Mn in the aqueous solutions has a catalytic effect on the hydrogen generation rate at room temperature. However, the precipitation of Mn3(PO4)2 on steel decreases the HER kinetics at high temperatures. These observations are also supported with SEM (Scanning Electron Microscopy) characterizations.
Ammonia mobility in chabazite: insight into the diffusion component of the NH<sub>3</sub>-SCR process (2016)

The diffusion of ammonia in commercial NH3-SCR catalyst Cu-CHA was measured and compared with H-CHA using quasielastic neutron scattering (QENS) and molecular dynamics (MD) simulations to assess the effect of counterion presence on NH3 mobility in automotive emission control relevant zeolite catalysts. QENS experiments observed jump diffusion with a jump distance of 3 Å, giving similar self-diffusion coefficient measurements for both Cu- and H-CHA samples, in the range of ca. 5-10 × 10(-10) m(2) s(-1) over the measured temperature range. Self-diffusivities calculated by MD were within a factor of 6 of those measured experimentally at each temperature. The activation energies of diffusion were also similar for both studied systems: 3.7 and 4.4 kJ mol(-1) for the H- and Cu-chabazite respectively, suggesting that counterion presence has little impact on ammonia diffusivity on the timescale of the QENS experiment. An explanation is given by the MD simulations, which showed the strong coordination of NH3 with Cu(2+) counterions in the centre of the chabazite cage, shielding other molecules from interaction with the ion, and allowing for intercage diffusion through the 8-ring windows (consistent with the experimentally observed jump length) to carry on unhindered.
Stretching of single DNA molecules by LB technique for restriction site mapping (2003)

Stretched single DNA molecules were prepared on substrates by Langmuir-Blodgett (LB) method for the restriction site mapping. Stretched single Lambda DNA and EcoRI bound to the DNA were observed by scanning near-field optical microscope (SNOM). As a result, the specific binding sites of EcoRI on the Lambda DNA molecules were determined.
Sulfone-mediated synthesis of substituted furans on solid support (2002)

The polymer-supported synthesis of 2,5-disubstituted furans using a traceless linker strategy is described. Deprotonation of a Merrifield resin-bound methyl aryl sulfone followed by reaction with diethyl chlorophosphate furnishes a phosphonate, the lithio-derivative of which reacts in situ with -methoxyaldehydes to yield vinylsulfones. Base-mediated isomerisation to the allylsulfones followed by reaction of the derived anions with aldehydes gives alcohols; trifluoroacetic acid treatment provides 2,5-disubstituted furans with concomitant cleavage from the solid support.

Deficits in cholinergic enzyme activities in septo-temporal regions of the senescent rat hippocampus, and in the forebrain of aged mice: effect of chronic Hydergine treatment. (1985)

Choline acetyltransferase and acetylcholinesterase activities in the septo-temporal regions of the rat hippocampus, and in the forebrain of mice were significantly decreased in senescent as compared with adult animals. A four week treatment of aged rats or mice with Hydergine resulted in the restoration of choline acetyltransferase activity.
A Human Monoclonal Antibody to rh^G (1986)

Hybridomas secreting a human monoclonal IgGi antibody against a variant of the rh^G antigen were produced from B lymphocytes of an Rh-negative donor with serum antibodies to D and C antigens. The antibody reacts by indirect hemagglutination with nearly all C- or D-positive cells, confirming the strong association in the expression of G with D or C antigens. The lack of antibody reactivity to C-negative D^u cells suggests a particular epitope on the D complex associated with the G antigen.
Characterization of soluble factors that induce the cytolytic activity and the expression of T cell growth factor receptors of a T cell hybrid. (1984)

A rat X mouse T cell hybrid (PC60) proliferates in the absence of T cell growth factor (TCGF) and its cytolytic activity can be induced by culture in mixed leukocyte culture supernatants or concanavalin A-activated rat spleen cell supernatant (CS) to lyse 51Cr-labeled tumor target cells. To characterize the factor(s) responsible for this reversible induction, serum-free CS was fractionated by reverse phase high performance liquid chromatography and by phenyl-Sepharose chromatography. A cytotoxicity-inducing activity (CIA) was separated from TCGF and macrophage-activating factor/interferon-gamma. CIA was found to be a macromolecule with an apparent molecular weight of 12,000-18,000 and a pI of 5.0 and 6.2. Its activity on PC60 cells depended on the addition of TCGF. Thus TCGF may have other effects on T cells than the induction of entry into cell cycle. The number of TCGF surface receptors on PC60 cells was measured using purified 3H-TCGF. TCGF receptors were undetectable on noninduced cells but appeared during induction. The expression of TCGF receptors was not induced either by TCGF or by CIA-containing supernatants or fractions alone, only by a combination of both. These results show that TCGF plays a role in the regulation of the expression of its own receptors.
Measurement and modeling of short copper cables for ultra-wideband communication (2006)

High-speed communication using the copper network, originally installed for telephony, is one of the dominant Internet access techniques. Several variants of a technology referred to as digital subscriber line (DSL) have been developed, standardized and installed during the last two decades. Essentially, DSL achieves high rates by exploiting wide bands of the copper cable channel. The shorter the cable, the wider the band that can be used efficiently for communication. Current DSL standards foresee the use of bands up to 30MHz. Cable properties have been studied by means of measurements, characterization and modeling up to frequencies of 30MHz. Recent investigations have shown that it is feasible both from technical and from economical point of view to exploit very short cables (up to 200m) even further and use bands above 30MHz. A prerequisite for further evaluation and the design of such ultra-wideband copper (UWBC) systems is the extension of existing cable models to higher frequencies. This paper presents wideband measurement results of insertion loss and crosstalk coupling in a 10-pair cable of various length values for frequencies up to 200MHz. We compare the results with extrapolations of cable models that are established in the 30MHz-range.
Quality of service (QoS) support for multimedia applications in large-scale networks (2006)

This dissertation studied issues pertaining to QoS provision for multimedia applications at the application layer. We initially studied Internet pathology and Internet stability by repeating experimental and analytical methods conducted by Paxson in 1996. No similar study was done in recent years. Our findings show that behavior of the Internet in 2006 are different from those reported in 1996 in some important aspects. Second, we investigated different stochastic models (e.g. self-similar processes, Auto-Regressive Integrated Moving-Average (ARIMA)) in order to find a suitable model that describes available bandwidth over time of an end-to-end path between two Internet hosts. Our finding of the suitable model is beneficial to predicting of future values of available bandwidth along an end-to-end path. To the best of our knowledge, no similar study was conducted. Third, we designed and evaluated a new path monitoring algorithm inferring available bandwidth of an end-to-end path without monitoring all the paths to minimize monitoring overhead. Our algorithm does not rely on underlying network-layer topology information as required in topology-aware path monitoring techniques. Finally, to complement the above study, we introduced our multicast protocol named core-set routing for transmitting multimedia data from a set of senders to a set of receivers, taking QoS into account. The protocol is suitable for interactive multi-sender multimedia applications such as video conferencing and network gaming.
