Adapting EMAP3D to parallel processing [for EM launcher modelling] (2001)

EMAP3D (Electromechanical Analysis Program in Three Dimensions) is a single-processor (serial) program that uses finite element (FE) methods to solve coupled electromagnetic, thermal and structural problems for high velocity conductors in transient electromagnetic fields. Its primary application has been the simulation of electromagnetic launchers and pulsed rotating machines. While ETVAP3D has been applied successfully to a wide range of problems, its serial execution time limits the achievement of finer detail in large problems, even on high performance vector machines. The present class of production simulations, involving 100,000 unknowns, can take a week to complete on time-sharing machines at computation centers. To reduce simulation time, a parallel implementation of the EMAPSD program has been undertaken. While vector parallel programming is straightforward and a reasonable approach, access to more than 16 vector processors is limited. The availability, low cost, and scalability of massively parallel processing (MPP) make MPP computing more attractive than vector-parallel processing. The number of MPP processors on PC Beowulf clusters usually ranges from 8 to 100 and can be as high as several thousand on IBM (SP) and Gray (T3E) systems. The authors have decoupled the matrix generation and solution components of the FE algorithm, thereby allowing us to use any of the new MPP-parallel solvers on the matrix equations. Since the number of zero matrix elements is high for EMAPSD problems, a sparse matrix solver is ideal. Hence, their parallel implementation uses the sparse iterative solvers of PETSc (Portable Extensible Toolkit for Scientific Computing). Here, they report the performance, scalability and use of PETSc preconditioners and solver algorithms as a "solution engine" for real EMAP3D simulations and test cases.

GM's PrEView Impact electric vehicle (1995)

This article reports on the GM PrEView Drive, a two-year, nationwide field test to obtain real-world data from consumers about electric vehicle (EV) performance and capabilities, determine infrastructure requirements to support electric vehicle use, and test and evaluate several advanced technologies that could be applied to future forms of transportation. GM is teaming with some of the nation`s utility companies and more than 1,000 consumers in 12 US cities who will test drive GM`s Impact EV for two- or four-week periods. Drivers selected typically drive about 56 km a day and have a home capable of being wired for the vehicle`s charging system. Test-drive feedback about product attributes, real-world driving situations, vehicle performance, and infrastructure needs will help GM with future vehicles plans by defining consumer preferences. Utilities will study the effects that EV use has on their generation, transmission, and distribution systems to determine the adequacy of local distribution facilities and the need for substation reinforcement strategies. The PrEView Drive also will determine adequate power supplies for residential charging, locate non-residential charging systems, and calculate the amount of local equipment needed to support them. Organizations developing electrical building codes will be able to obtain information needed to begin accommodatingmore » EV charging stations and developing and adopting power-quality and power-factor standards for chargers.« less
Quasi-one-dimensional photonic crystal as a compact building-block for refractometric optical sensors (2005)

We report the fabrication and the characterization of the refractometric and thermo-optical properties of a quasi-one-dimensional waveguide photonic crystal-a strong, 76-/spl mu/m-long Bragg grating. The transmission spectra (around 660 nm) of the structure have been measured as a function of both the cladding refractive index and the temperature. The transmission stopband was found to shift by 0.8-nm wavelength for either a cladding refractive index change of 0.05 or a temperature change of 120 K. The steep stopband edges provide a sensitive detection method for this band shift, by monitoring the transmitted output power.
A voice controlled telephone dialer (1989)

The design and implementation of a voice controlled telephone dialer is described. The dialer is based on a speaker-dependent speech recognition system and is controlled by a Commodore 64 microcomputer. The purpose of the system is to recognize spoken digits to replace normal pushbutton dialing, or to recognize names stored in a directory and then automatically dial the corresponding telephone numbers upon request. Software necessary to evaluate and operate the system is presented. The hardware designed to interface the telephone with the microcomputer is given. The performance of the system is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Human Infection with<i>Ascaris lumbricoides</i>Is Associated with Suppression of the Interleukin-2 Response to Recombinant Cholera Toxin B Subunit following Vaccination with the Live Oral Cholera Vaccine CVD 103-HgR (2001)

To investigate the potential immunomodulatory effects of concurrent ascariasis on the cytokine response to a live oral vaccine, we measured cytokine responses to cholera toxin B subunit (CT-B) following vaccination with the live oral cholera vaccine CVD 103-HgR in Ascaris lumbricoides-infected subjects randomized in a double-blind study to receive two doses of either albendazole or placebo prior to vaccination and in a group of healthy U.S. controls. Postvaccination cytokine responses to CT-B were characterized by transient increases in the production of interleukin-2 (IL-2; P = 0.02) and gamma interferon (IFN-gamma; P = 0.001) in the three study groups combined; however, postvaccination increases in IFN-gamma were significant only in the albendazole-treated A. lumbricoides infection group (P = 0.008). Postvaccination levels of IL-2 were significantly greater in the albendazole-treated group compared with the placebo group (P = 0.03). No changes in levels of Th1 and Th2 cytokines in response to control ascaris antigens were observed over the same period. These findings indicate that vaccination with CVD 103-HgR is associated with a Th1 cytokine response (IL-2 and IFN-gamma) to CT-B, that infection with A. lumbricoides diminishes the magnitude of this response, and that albendazole treatment prior to vaccination was able to partially reverse the deficit in IL-2. The potential modulation of the immune response to oral vaccines by geohelminth parasites has important implications for the design of vaccination campaigns in geohelminth-endemic areas.
High Temperature Polymers from Thermally Curable Oligomers (1985)

The synthesis, physical and mechanical properties of thermally curable oligomers primarily for use as high temperature composite matrices are reviewed. High temperature in this context is defined as having usable mechanical properties at 177°C and higher.
Variability of response to lithium augmentation in refractory depression (1986)

Eighty-four patients with major depression refractory to a controlled antidepressant trial had lithium added to their ongoing treatment. Objective symptom ratings showed highly significant improvement in the sample as a whole. At discharge or after 24 days, 31% of the patients showed a marked response, 25% a partial response. Thus, 56% of patients had a significant positive response, while 44% were nonresponders. This study indicates that response to lithium augmentation may be quite variable and a 3-week trial is necessary to assess full benefit.
Symbiotic Nitrogen Fixation in the Fungus Gardens of Leaf-Cutter Ants (2009)

Bacteria-mediated acquisition of atmospheric N2 serves as a critical source of nitrogen in terrestrial ecosystems. Here we reveal that symbiotic nitrogen fixation facilitates the cultivation of specialized fungal crops by leaf-cutter ants. By using acetylene reduction and stable isotope experiments, we demonstrated that N2 fixation occurred in the fungus gardens of eight leaf-cutter ant species and, further, that this fixed nitrogen was incorporated into ant biomass. Symbiotic N2-fixing bacteria were consistently isolated from the fungus gardens of 80 leaf-cutter ant colonies collected in Argentina, Costa Rica, and Panama. The discovery of N2 fixation within the leaf-cutter ant-microbe symbiosis reveals a previously unrecognized nitrogen source in neotropical ecosystems.

A cytotoxic anti-IL-3Rα antibody targets key cells and cytokines implicated in systemic lupus erythematosus (2016)

To date, the major target of biologic therapeutics in systemic lupus erythematosus (SLE) has been the B cell, which produces pathogenic autoantibodies. Recently, targeting type I IFN, which is elaborated by plasmacytoid dendritic cells (pDCs) in response to endosomal TLR7 and TLR9 stimulation by SLE immune complexes, has shown promising results. pDCs express high levels of the IL-3Rα chain (CD123), suggesting an alternative potential targeting strategy. We have developed an anti-CD123 monoclonal antibody, CSL362, and show here that it affects key cell types and cytokines that contribute to SLE. CSL362 potently depletes pDCs via antibody-dependent cell-mediated cytotoxicity, markedly reducing TLR7, TLR9, and SLE serum-induced IFN-α production and IFN-α-upregulated gene expression. The antibody also inhibits TLR7- and TLR9-induced plasmablast expansion by reducing IFN-α and IL-6 production. These effects are more pronounced than with IFN-α blockade alone, possibly because pDC depletion reduces production of other IFN subtypes, such as type III, as well as non-IFN proinflammatory cytokines, such as IL-6. In addition, CSL362 depletes basophils and inhibits IL-3 signaling. These effects were confirmed in cells derived from a heterogeneous population of SLE donors, various IFN-dependent autoimmune diseases, and healthy controls. We also demonstrate in vivo activity of CSL362 following its s.c. administration to cynomolgus monkeys. This spectrum of effects provides a preclinical rationale for the therapeutic evaluation of CSL362 in SLE.
Optimizing QoS aware ethernet spanning trees (2005)

Ethernet is gaining in importance in both access and metro networks. As a layer 2 technology, Ethernet gives a basic framework for routing, QoS and traffic engineering (TE), as well as a protocol for building up trees. IEEE 802.1 standards define default configuration parameters considering the topology only. We propose methods for resource management in Ethernet networks through spanning tree optimization for both STP (spanning-tree protocol) (IEEE 802.1D) and MSTP (multiple spanning-tree protocol) (IEEE 802.1s). As a result of optimization, we assign costs to the bridge ports in the network to build trees based on these costs via STP and MSTP. These trees yield optimized routing, TE and support for different QoS classes. We show on typical metro-access networks that, through optimization, the total network throughput can be significantly increased for both enforcing fairness or allowing starvation of some demands. This gain can be realized by simultaneously assigning demands to trees and routing these trees.
Gitelman 증후군 1예 (2003)

Gitelman`s syndrome (GS) (also called tubular hypomagnesemia-hypokalemia with hypocalciuria), an autosomal recessive disorder, is often not diagnosed until late childhood or even adulthood. GS is a more benign condition than Batter`s syndrome. However, the syndrome is usually symptomatic and can be associated with serious clinical manifestations such as cramps, severe fatigue, polyuria, and nocturia. Patients with GS have mutations in the gene coding for the thiazide-sensitive Na-Cl cotransporter in the distal tubule. A defect in this transporter can account for both the magnesium wasting and the often marked decrease in calcium excretion (the opposite of the hypercalciuria seen in classic Bartter`s syndrome). There is no direct correlation between the clinical phenotype and the underlying genotypic abnormality. A 37-year-old man was admitted with complaints of intemittent chest tightness and generalized weakness. He had no history of laxative or diuretic abuse or of vomiting, and he was taking no medications. Physical examination revealed a well-developed. His blood pressure was 124/80 mmHg. On admssion, laboratory values were: hemoglobin 17.0 g/dl, hematocrit 48.9%, white blood cell count 11,500/mm3, platelet 424,000/mm3, BUN 18 mg/dl, serum creatinine 1.20 mg/dl, AST 27 IU/L, ALT 29 IU/L, serum sodium 137 mEq/L, potassium 2.5 mEq/L, calcium 10 mg/dl, magnesium 1.2 mg/dl, TTKG 5.0, supine PRA 32.1 ng/ml/hr, supine aldosterone, 218.9 pg/ml, pH 7.44, PCO2 40.5 mmHg, HCO3- 26.9 mEq/L. Follow-up laboratory values revealed: serum sodium 133 mEq/L, potassium 2.2 mEq/L, calcium 9.8 mg/dl, magnesium 1.4 mg/dl, TTKG 5.3, supine PRA 48.2 ng/ml/hr, supine aldosterone 402.9 pg/ml, pH 7.45 PCO2 39 mmHg HCO3- 27.4 mEq/L, 24 hours urine calcium/creatinine ratio 0.09, fractional excretion of magnesium (FEMg) 56.5%. The patient was discharged on spirolactone 100 mg. Three monthe later, he remained asymptomatic and near normal serum potassium level.
Zigbee-based intra-car wireless sensor networks: a case study (2007)

There is a growing interest in eliminating the wires connecting sensors to the microprocessors in cars due to an increasing number of sensors deployed in modern cars. One option for implementing an intra-car wireless sensor network is the use of ZigBee technology. In this article we report the results of a ZigBee-based case study conducted in a vehicle. Overall, the results of the experiments and measurements show that ZigBee is a viable and promising technology for implementing an intra-car wireless sensor network.
Effect of Intramuscularly Injected Polyprenols on Influenza Virus Infection in Mice (2000)

This study demonstrates the possibility of achieving a prophylactic effect by intramuscular injection of Abies sibirica polyprenols for the control of influenza virus infection in mice. One of the five polyprenol preparations tested, preparation N1, which had the lowest hydrophilic-lipophilic balance (8.6), produced a significant protective effect when injected in a dose of 2000 microg/mouse 2 days before aerosol infection of mice with influenza virus. A moderate protective effect was also observed using a second preparation, designated N2. One day after aerosol infection, animals pre-treated with 2000 microg doses of the polyprenol preparations or Hanks' solution showed no difference in the level of interferon accumulation in the lungs. Three days after injection of preparation N2 and N1, a significant decrease in spleen and thymus weights was, observed in the mice. One day after injection of these preparations, the number of lymphocytes in the bronchoalveolar tract of the mice exceeded almost twice that seen in mice treated with placebo. After 3 days, relative and absolute numbers of macrophages decreased, whereas those of lymphocytes increased significantly. Three days after the administration of preparations N1 and N2, macrophages became approximately twice as active in absorbing zymozan granules. Preparation N1 affected the system of superoxide radical anion production to a greater extent than preparation N2. The production of radical anions by the macrophages of the bronchoalveolar tract in the mice, 1 day after intramuscular injection of preparation N1, was significantly higher than that seen on day 3 and that induced by preparation N2 1 and 3 days after injection. These data indicate that emulsions of polyprenols that have relatively low hydrophilic-lipophilic balance, inhibit influenza virus infection in mice through a modulation of the host immune response.
Terapia intra-articolare con acido ialuronico (Hylan G-F 20) sotto guida ecografica nell'artrosi dell'anca. Risultati clinici a 12 mesi Intra-articulaar treatment with Hylan G-F 20 under ultrasound guidance in hip osteoarthritis. Clinical results after 12 months follow-up (2005)

SUMMARY Hip is a site very commonly affected by osteoarthritis (OA), yet few data exist in literature regarding intra-articulaar use of hyaluronic acid in this pathology. We evaluated the efficacy of Hylan G-F 20 hip viscosupplementation performed under ultrasound guidance. We enrolled 26 patients affected by symptomatic hip OA and treated them with a single intraarticular injection of Hylan G-F 20, which could be repeated every two months. The injection was performed under ultrasound guidance with an antero-superior approach. Treatment efficacy was assessed through Lequesne index, visual analogue scale (VAS) pain quantification, and NSAID intake at the timepoint zero (baseline), and after 2, 6 and 12 months. We observed a statistically significant reduction of all considered parameters at the timepoints 2 and 6 months, when compared to baseline. At 12 months the changes were still statistically significant for all parameters for about 50% of the patients. No side effect was observed, nor systemic complication. Viscosupplementation is a promising approach for hip OA, although further and wider studies are wanted to determine how long the beneficial effect lasts, and what is the optimal number of injections to administer.
Removal of Nutrients in Wastewater by using Magnesium Salts (1998)

Abstract The removal of ammonia nitrogen and phosphorus from wastewater by precipitating out with magnesium salts was showed. Factors of pH, reaction time, N/P ratio, and dissolution test were investigated to find optimal conditions for magnesium ammonium phosphate (MAP) formation. The investigated conditions were also applied to toxic industrial wastewater. SEM and EDS analyses indicated that the precipitate was magnesium ammonium phosphate that was fine crystals of Mg and P compounds. The removal of ammonia and phosphorus increased with pH up to 10.5 where 82.6% and 97% of ammonia nitrogen and phosphorus were removed. It was found that minimum 10 minutes reaction was required for the nutrients removal. However, a small amount of phosphorus dissolved after 60 minutes. Ammonia nitrogen was well removed at one mole to two moles of magnesium. But at doses higher than two moles of magnesium, ammonia nitrogen increased due probably to the decreased pH. Bittern and sea water proved to be excellent coagulants for nutrient removal from industrial wastewater. The comparative study of different magnesium sources showed that bittern was the most efficient as 72% 99% of ammonia and phosphorus, respectively, were removed.

Liquid distribution in trickle‐bed reactors: Part II. Tracer studies (1978)

Abstract An aqueous solution of potassium chloride tracer was introduced at a central location in the water feed to a trickle bed, and the tracer concentration was measured at various radial positions and bed depths. From the model and parameters of liquid distribution proposed in Part I, tracer concentrations can also be predicted. The predicted and experimental concentrations usually agreed within a few percent, providing an independent evaluation of the flow distribution model.
Bio-oil Production from Biomass: Steps toward Demonstration (2011)

Metso, UPM, Fortum, and VTT have developed the world’s first integrated bio-oil production concept to provide an alternative to fossil fuels. The consortium has constructed an up to 7 tons/day bio-oil production pilot unit, which uses a bubbling fluidized-bed (BFB) pyrolysis reactor integrated with a conventional fluidized-bed boiler. Proof-of-concept has been carried out; close to 90 tons of bio-oil has been produced from sawdust and forest residues at high availability. Around 40 tons of bio-oil has been combusted in Fortum’s 1.5 MW district heating plant in Masala, Finland, with high efficiency. Flue gas emissions were close to those of heavy fuel oil, at 4% O2, CO emissions ranged from 0 to 10 ppm and NOx emissions ranged from 300 to 400 ppm. Organic compounds were under 5 mg m–3 N–1, and particulate emissions were in the range of 150–200 mg m–3 N–1. No odor emissions occurred. Development of the concept has been supported by experimental work on fast pyrolysis at VTT. This paper presents the recent results from the piloting project covering the whole chain from feedstock processing to bio-oil combustion, including the quality control system with online gas and liquid analyzers. The research supporting the pilot project, from various laboratory-scale units to systematic analytical development, is discussed, and the potential for market introduction of the new technology in forest product industries in western Europe and North America is described.
Removal of subjective redundancy by adaptive quantization of DCT coefficients (2002)

The removal of subjective redundancy in image coding has been playing a very important role in studies of the low bit rate video communications to attain even greater levels of signal compression. This paper discusses in depth the psychovisual interactions between the basis pictures (components) of DCT in the transform domain, and based on this, suggests a coding scheme to further reduce the required bit rate by adaptively quantizing the DCT coefficients. The general goal is to maintain the perception of reconstructed images as good as possible, therefore, several human visual system's characteristics such as the responses to intensity and to spacial frequency as well as the spacial masking effect are fully exploited. Some experiments are carried out, and very encouraging results are obtained.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
