Temperature-induced migration of a bubble in a soft microcavity (2011)

We perform studies of pancake-like shaped bubbles submitted to a temperature gradient in a micrometric height Hele-Shaw cell. We show that under the experimental conditions, usually found in microfluidic devices, the temperature-induced dilation of the cavity overcomes the thermocapillary convection due to surface tension variation, effectively driving the bubble toward the cold side of the cavity. The bubble velocity is experimentally characterized as a function of the bubble radius, the temperature gradient, and the initial Hele-Shaw cell thickness. We propose a theoretical prediction of the bubble velocity, based on the analytical resolution of the hydrodynamical problem. The equations set closure is ensured by the pressure value near the bubble and by the dissipation in the moving meniscus.
Potential‐Controlled Chromatography of Short‐Chain Carboxylic Acids (2003)

Abstract A chromatographic column was constructed which could be operated with an electrically conductive stationary phase of graphite particles. This column allowed chromatographic experiments at variable electric potentials of the column material. The chromatographic behavior of selected carboxylic acids was significantly influenced at positive column potentials. An equimolar mixture of three different carboxylic acids were separated at a potential of +600 mV (versus. Ag/AgCl). Surprisingly, the stereoisomers maleic and fumaric acid, which are identical in molecular mass and charge, could also be separated. Further improvements to the chromatographic performance were achieved by applying potential drops and linear potential gradients.
AVM description compilation using types as modes (2003)

This paper provides a method for generating compact and efficient code to implement the enforcement of a description in typed feature logic. It does so by viewing information about types through the course of code generation as modes of instantiation --- a generalization of the common practice in logic programming of the binary instantiated/variable mode declarations that advanced Prolog compilers use. Section 1 introduces the description language. Sections 2 and 3 motivate the view of mode and compilation taken here, and outline a mode declaration language for typed feature logic. Sections 4 through 7 then present the compiler. An evaluation on two grammars is presented at the end.
Electrical properties of chick skeletal muscle fibers developing in cell culture (1971)

Abstract The membrane properties of individual skeletal muscle cells were studied with intracellular microelectrodes as the fibers developed, in vitro , from mononucleated precursor cells. Passive membrane constants were determined from analysis of transmembrane potential responses to pulses of current assuming the myotubes could be represented as sealed, finite cylinders. Resting membrane potentials increased from 10–15 mV in the shortest, youngest myotubes to ca. 60 mV in the longest, most mature fibers. The increase in membrane potential was not associated with a change in membrane resistivity. Action potentials occurred spontaneously in the most mature cells and repetitive spikes could be evoked by depolarizing current pulses. Spikes and twitches could be evoked in young myotubes provided the membrane was first hyperpolarized to 60–70 mV. Apparently the membrane potential is the rate limiting factor in the maturation of excitation‐contraction mechanisms.
Physiological and histological changes in skeletal muscle following in vivo gene transfer by electroporation (2011)

Electroporation (EP) is used to transfect skeletal muscle fibers in vivo, but its effects on the structure and function of skeletal muscle tissue have not yet been documented in detail. Methods We studied the changes in contractile function and histology after EP to determine the mechanism of recovery, the extent of myofiber damage, and the efficiency of expression of a green fluorescent protein (GFP) transgene in the tibialis anterior (TA) muscle of adult male C57Bl/6J mice. Results Immediately after EP, contractile torque decreased by ~ 80% from pre-EP levels. Within 3 hr, torque recovered to ~ 50% but stayed low until day 3. Functional recovery progressed slowly and was complete at day 28. In muscles depleted of satellite cells by X-irradiation, torque remained low after day 3, suggesting that myogenesis is necessary for complete recovery. In unirradiated muscle, myogenic activity after EP was confirmed by an increase in fibers with central nuclei or developmental myosin. Damage after EP was confirmed by the presence of necrotic myofibers infiltrated by CD68+ macrophages, which persisted in electroporated muscle for 42 days. Expression of GFP was detected at day 3 after EP and peaked on day 7, with ~ 25% of fibers transfected. The number of fibers expressing GFP, the distribution of GFP+ fibers, and the intensity of fluorescence in GFP+ fibers were highly variable. We conclude that EP of murine TA muscles produces highly variable and low levels of transgene expression, and causes extensive damage that requires myogenesis for recovery.
Cranking the Immunologic Engine with Chemotherapy: Using Context to Drive Tumor Antigen Cross-Presentation towards Useful Antitumor Immunity (2006)

This review shows how tumor antigen cross-presentation is affected by the major therapeutic modalities including chemotherapy, radiotherapy, and surgery. We argue that this process could affect the way that a tumor works as its own cellular vaccine, and that it is differentially modulated by the choice of treatment.
High density monolayer of diisocyanide on gold surface as a platform of supported Rh-catalyst for selective 1,4-hydrogenation of α,β-unsaturated carbonyl compounds (2014)

A high density monolayer of diisocyanide on gold surface was utilized as a platform of supported Rh catalyst for selective 1,4-hydrogenation of α,β-unsaturated carbonyl compounds. The catalyst exhibited high turnover numbers in a range of 50 000 to 150 000 per Rh atom and showed steady catalyst performance over six recycle usages.
Angular electromagnetic response of double-ring metamaterials for TE polarization (2011)

We investigate transmission characteristics in symmetric planar double-ring metamaterials at oblique angles of incidence theoretically. The double-ring microwave metamaterials are used to study resonant response to incident TE electromagnetic wave. The trapped-mode resonant feature results from the excitation of antisymmetric current mode and the quality factor is associated to the angle of incidence.
Impacto de stents farmacológicos em pacientes com doença arterial coronária estável submetidos a intervenção coronária percutânea na prática diária do mundo real (2010)

INTRODUÇÃO: Estudos recentes incluindo pacientes portadores de doença coronária estável sugerem ausência de benefício clínico da estratégia inicial de intervenção coronária percutânea com stents não-farmacológicos associada a terapia medicamentosa otimizada vs. terapia medicamentosa otimizada isolada. No entanto, o tratamento ideal para pacientes com doença coronária estável no mundo real permanece controverso. Reportamos o impacto dos stents farmacológicos (SF) em pacientes portadores de doença coronária estável tratados na prática clínica diária. MÉTODO: Entre maio de 2002 e novembro de 2009, 1.814 pacientes portadores de doença coronária estável (angina estável ou isquemia silenciosa) foram prospectivamente incluídos no Registro DESIRE, e o seguimento clínico de até 8 anos (média de 3,9 ± 2 anos) foi realizado em 98% desses pacientes. RESULTADOS: A média das idades era de 64,2 ± 10,8 anos, 28% tinham diabetes melito, 21% tinham infarto do miocárdio prévio e 51,7%, revascularização prévia. A artéria descendente anterior foi o vaso-alvo mais tratado (42%), e, considerando-se o total de lesões (n = 2.701), 66,3% delas eram de elevada complexidade (tipos B2/C). Ao final do procedimento, o sucesso angiográfico foi de 99%. No seguimento clínico tardio, as taxas cumulativas de eventos adversos foram: morte cardíaca, 3,4%; infarto do miocárdio, 5,5%; revascularização da lesão-alvo (RLA), 4,8%; e trombose de stent, 0,8%. CONCLUSÃO: A utilização de SF na doença coronária estável esteve associada a excelente evolução clínica tardia, incluindo taxa cumulativa de RLA < 5%, e segurança sustentada. Comparados a dados históricos, tais achados demonstram grande benefício dos SF nessa população, sugerindo que a intervenção coronária percutânea com SF pode ser uma alternativa inicial segura e eficaz no tratamento de pacientes com doença coronária estável.

An Energy Efficiency Analysis of an Industrial Reheating Furnace and an Implementation of Efficiency Enhancements Methods (2014)

Rapid consumption of energy resources, increasing energy needs, the competitive conditions in the industry and environmental concerns, all of those call for efficient use of energy resources. In this context, energy efficiency studies were carried out in a rolling mill of a reheating furnace of an integrated industrial enterprise. In studies, some important efficiency measurements were conducted, mass and energy balances were established by using the results of these measurements and the operating data of the plant along with energy saving opportunities, with the specified amounts and repayment periods were determined. Energy conservation studies that can be realized in the reheating furnace were considered including operation of the reheating furnace with the pertinent excess air coefficient, compensation of the air leakage losses in the recuperator and establishment of the economizer in the furnace. As a result of these investigations some saving opportunities were determined and a new recuperator, economizer and gas analyzer were installed in the reheating furnace leading in total of 2,913,924 kcal/h of energy savings. After the implementation of energy saving measures, reheating furnace efficiency was increased from 61.83% to 69.43%.
Conditions established in a laser thermonuclear reactor chamber by a microexplosion of a target (1975)

Calculations are made of the quantities (pressure, temperature, mass evaporated from the walls, energy evolved by neutrons in the lithium blanket, etc.) representing physical conditions in a reactor chamber. These conditions can be used as the starting point for the selection of the engineering design of a laser thermonuclear reactor.
Nonlinear Vehicle Velocity Observer with Road-Tire Friction Adaptation (2006)

A nonlinear observer for lateral velocity of an automotive vehicle is extended for robustness with respect to unknown road surface conditions. The observer uses a friction model parametrized with the maximum road-tire friction coefficient, and an adaptive parameter update law is designed for estimation of this coefficient. The adaptive nonlinear observer is proven to be uniformly globally asymptotically stable under a uniform 5-persistency-of-excitation condition, and a set of additional technical assumptions, using results related to Matrosov's theorem. The adaptive observer is validated using experimental data from a car
Laser Processing Technology of Medical Devices. (2000)

In the laser micro processing applications, medical devices are bound to attract attention with great interest. Although, compared with the conventional industrial application, it did not spread sufficiently, however, the development of the medical devices which applied laser micro processing technology, have shownconsiderable improvement in the application result. The present work shows such applications for practical use and examines the future prospects.
Transmit Laser Selection for Underwater Visible Light Communication Systems (2019)

Visible light communication (VLC) has the potential to serve as a high-speed underwater wireless connectivity solution to support real-time image and video transmission. Underwater propagation medium imposes additional challenges on the design of VLC systems which were originally proposed for indoor applications. Temperature and salinity fluctuations result in fluctuations of the refractive index of seawater and eventually introduce turbulence-induced fading. In this paper, to mitigate the effects of fading, we propose transmit laser selection for a diver-to-diver underwater VLC link where the transmitter has multiple laser sources and the receiver has one photodetector. The source with the highest received instantaneous signal-to-noise ratio is selected for transmission while the remaining sources remain idle. We derive a closed-form expression for asymptotical bit error rate over log-normal distributed underwater turbulence channels and derive the achievable diversity order. We further present simulation results to confirm our derivations and diversity gain analysis.
Composition of a protein antifreeze from larvae of the beetle, Tenebrio molitor (1979)

Abstract A thermal hysteresis producing antifreeze protein was isolated from larvae of the beetle, Tenebrio molitor . This is the first thermal hysteresis protein purified from an insect. The specific activity of the Tenebrio antifreeze is somewhat greater than that of the fishes. The composition of the Tenebrio protein is quite different from those of the fish protein antifreezes. The most obvious difference is the lack of a large alanine component in the Tenebrio antifreeze. The significance of the differences are discussed.
Structure of Active Adlayers on Bimetallic Surfaces:  Oxygen Reduction on Au(111) with Bi Adlayers (2002)

The structure of Bi adlayers on the Au(111) electrode surface during the course of O2 reduction has been investigated by in situ surface X-ray scattering. Under oxygen reduction conditions, both the low-coverage (2 × 2)-Bi and the close-packed (p × √3)-2Bi adlayer structures are stable. We developed an electrochemical drop cell that provides a more uniform potential distribution during high current conditions compared with commonly used thin-layer cells. Our results clearly indicate distinctly different catalytic properties for the two ordered bismuth adlayer phases. In the potential region corresponding to the (2 × 2)-Bi phase, O2 reduction is promoted to a four-electron reaction, albeit with relatively slow kinetics. The close-packed (p × √3)-2Bi phase, formed at more negative potentials, appears to have a limited number of sites available for four-electron reduction, but the reaction kinetics on this adlayer is enhanced by an increased overpotential.
Spatially Coupled Generalized LDPC Codes: Introduction and Overview (2018)

Generalized low-density parity-check (GLDPC) codes are a class of LDPC codes in which the standard single parity check (SPC) constraints are replaced by more general constraints, viz., constraints defined by a linear block code. These stronger constraints typically result in improved error floor performance, due to better minimum distance and trapping set properties, at a cost of some increased decoding complexity. In this paper, we summarize some recent results on spatially coupled generalized low-density parity-check (SC-GLDPC) codes. Results are compared to GLDPC block codes and the advantages and disadvantages of SC-GLDPC codes are discussed.
Electromagnetic diffraction and subwavelength mask lithography: numerical feasibility study (2000)

Diffraction of light by a single aperture of subwavelength size into lossy media is numerically investigated. The results suggest possibility of fabrication of subwavelength diffractive optical elements by conventional contact or proximity lithography with thin resist layer.
Quinine-Resistant <i>Plasmodium berghei</i> in Mice (1965)

During induction of chloroquine resistance, Plasmodium berghei developed resistance to quinine administered in doses near the maximum amounts tolerated by mice. Resistant parasites did not form malarial pigment. Normal sensitivity to both quinine and chloroquine returned and pigment formation resumed during serial passage of the parasites through untreated mice.
Examining the Linear Complexity of Multi-Value Sequence Generated by Power Residue Symbol (2015)

In our previous work, k-value pseudo random sequence generated by power residue symbol has been researched. The sequence is generated by applying a primitive polynomial over odd characteristics field, trace function, and power residue symbol. The sequence has some important features such as period, periodic autocorrelation, and linear complexity. In this paper, by applying an additional process to the previous procedure, an extended multi-value sequence is generated. Its features, such as the period, periodic autocorrelation, periodic crosscorrelation, and linear complexity are examined in this paper. According to the results, the new sequence also has some interesting features.
Acceleration of orbital-free first principles calculation with graphics processing unit GPU (2010)

Computational material design requires efficient algorithms and high-speed computers for calculating and predicting material properties. The orbital-free first principles calculation (OF-FPC) method, which is a tool for calculating and designing material properties, is an O(N) method and is suitable for large-scaled systems. The stagnation in the development of CPU devices with high mobility of electron carriers has driven the development of parallel computing and the production of CPU devices with finer spaced wiring. We, for the first time, propose another method to accelerate the computation using Graphics Processing Unit (GPU). The implementation of the Fast Fourier Transform (CUFFT) library that uses GPU, into our in-house OF-FPC code, reduces the computation time to half of that of the CPU.
Positive Association of the β Fibrinogen H1/H2 Gene Variation to Basal Fibrinogen Levels and to the Increase in Fibrinogen Concentration during Acute Phase Reaction but not to Coronary Artery Disease and Myocardial Infarction (1997)

Obviously, the H2 allele of the fibrinogen H1/H2 genotype does not only influence basal fibrinogen concentrations, but particularly also the extent of fibrinogen level increase during acute phase reaction. Whereas the fibrinogen plasma level is positively associated with coronary artery disease and myocardial infarction, the H2 allele-although exhibiting an association with elevated fibrinogen levels-was not positively associated with CAD and MI.

New High-Strength Weldable Titanium Alloy T110 (2006)

T110 experimental high-strength weldable titanium alloy was developed. Distribution of alloying elements and impurities in length and section of 400 mm diameter ingots from alloys of Ti-Al-Mo-V-Nb-Fe-Zr system, produced by the method of electron-beam melting with an intermediate crucible (EBMC) was investigated. Optimal operating modes of melting, deformation, heat treatment, welding of T110 alloy based on this alloying system were determined in order to obtain required chemical composition, macro-and microstructure, a level of mechanical characteristics. The mechanical and fatigue characteristics for parent metal and welded joints were determined. It was found that by mechanical characteristics the alloy does not comply and by a level of plasticity exceeds VT22 commercial alloy. The cyclic life of T110 titanium alloy for parent material exceeds this characteristic of VT22 alloy. The cyclic life of T110 alloy welded joints does not depend on welding method. The alloy developed is good technological material: it is easily deformed, quenched by air after annealing, good welded by all kinds of welding. In this case the welded joint have a strength level of 0,95 and KCV of 0,8 of a parent metal properties, minimum.
Aortic leucine-to-glutamate pathway: metabolic route and regulation of contractile responses (2002)

Rat aortic endothelium is differentiated regionally for three signal pathways capable of regulating the cGMP content of the underlying smooth muscle. Formation of nitric oxide (NO) from L-arginine and of glutamate from L-leucine increase cGMP; however, formation of prostaglandin H2 (PGH2) decreases cGMP. All three have peak activity in the windkessel area just distal to the aortic arch and decrease peripherally. We report evidence that the biochemical route of the leucine-to-glutamate (Leu-->Glu) pathway is via metabolism of leucine to acetyl CoA, that the controlling reaction of the pathway is mediated by the branched chain alpha-ketoacid dehydrogenase complex (BCDC), and that glutamate formation via the Leu-->Glu pathway is a major source of aortic segment free glutamate in vitro. Interruption of the pathway by treatment of precontracted rat aortic rings in vitro with each of three classes of inhibitors (leucine analogs, competitors for the BCDC reaction, or inhibitors of L-glutamate transport) enhances contractile responses. The enhancement requires an intact endothelium and is not owing to reductions in NO formation. The results support the hypothesis that the Leu-->Glu pathway functions in the regulation of aortic contractility and compliance.
