Meta Conjugation Effect on the Torsional Motion of Aminostilbenes in the Photoinduced Intramolecular Charge-Transfer State (2007)

The photochemical behavior of a series of trans-3-(N-arylamino)stilbenes (m1, aryl = 4-substituted phenyl with a substituent of cyano (CN), hydrogen (H), methyl (Me), or methoxy (OM)) in both nonpolar and polar solvents is reported and compared to that of the corresponding para isomers (p1CN, p1H, p1Me, and p1OM). The distinct propensity of torsional motion toward a low-lying twisted intramolecular charge-transfer (TICT) state from the planar ICT (PICT) precursor between the meta and para isomers of 1CN and 1Me reveals the intriguing meta conjugation effect and the importance of the reaction kinetics. Whereas the poor charge-redistribution (delocalization) ability through the meta-phenylene bridge accounts for the unfavorable TICT-forming process for m1CN, it is such a property that slows down the decay processes of fluorescence and photoisomerization for m1Me, facilitating the competition of the single-bond torsional reaction. In contrast, the quinoidal character for p1Me in the PICT state kinetically favors both fluorescence and photoisomerization but disfavors the single-bond torsion. The resulting concept of thermodynamically allowed but kinetically inhibited TICT formation could also apply to understanding the other D-A systems, including trans-4-cyano-4'-(N,N-dimethylamino)stilbene (DCS) and 3-(N,N-dimethylamino)benzonitrile (3DMABN).
T<scp>RIBLER</scp>: a social‐based peer‐to‐peer system (2007)

Abstract Most current peer‐to‐peer (P2P) file‐sharing systems treat their users as anonymous, unrelated entities, and completely disregard any social relationships between them. However, social phenomena such as friendship and the existence of communities of users with similar tastes or interests may well be exploited in such systems in order to increase their usability and performance. In this paper we present a novel social‐based P2P file‐sharing paradigm that exploits social phenomena by maintaining social networks and using these in content discovery, content recommendation, and downloading. Based on this paradigm's main concepts such as taste buddies and friends, we have designed and implemented the T RIBLER P2P file‐sharing system as a set of extensions to BitTorrent. We present and discuss the design of T RIBLER , and we show evidence that T RIBLER enables fast content discovery and recommendation at a low additional overhead, and a significant improvement in download performance.

A Method of Anti-lock Braking System for Higher Braking Stability of a Three-wheeled motorcycle (2021)

This paper proposes an anti-lock brake system (ABS) with a good maneuver performance for three-wheeled motorcycles. The proposed configuration of the ABS method includes signal processing and control algorithm. It avoids wheel lock-up and maintains the controllability of the motorcycles. When independently control the wheels, the proposed method balances the braking pressure of both left and right wheels and reduces the yaw motion of the motorcycles. Several tests were executed to verify the braking performance on the uniform, and u jump road surface. The results show that the proposed method successfully adjusts the braking pressure of the wheels. Braking maneuvers will become safer and more efficient through the utilization of the advanced safety techniques for anti-lock braking and the performance meets the regulations for all the tests.

Inhibition of Surface-Induced Platelet Activation by Nitric Oxide (1995)

This study was undertaken to determine whether the nitric oxide/platelet cyclic guanosine monophosphate (NO/cGMP) pathway might be used to reduce platelet activation by artificial surfaces. Because serotonin release (SR) is a platelet activation indicator, rabbit platelets in their own plasma (PRP) were labeled with 3H-serotonin. Labeled PRP was incubated with glass beads for 5-10 min, at 37 degrees C with gentle agitation, and SR was measured. PRP pretreatment with NO gas or nitroprusside + N-acetylcysteine inhibited SR 50%. Dose response studies indicate the existence of an optimal NO concentration above which its inhibitory effect is diminished. The guanylate cyclase inhibitor methylene blue attenuates the NO effect, implicating cGMP in NO mediated inhibition of surface induced platelet activation. Adult pigs were supported on a membrane oxygenator in an in vitro model of cardiopulmonary bypass (CPB). Introduction of NO gas into the oxygenator sweep gas at 500 ppm reduced platelet adherence to the oxygenator surfaces, increased circulating platelet counts, and decreased the rate of platelet aggregation (whole blood impedance platelet aggregometry) compared with the results of the control animals. Indications of NO toxicity were seen when the NO flow rate was increased to 1,000 ppm. These studies support the hypothesis that NO reduces platelet activation by artificial surfaces in clinical devices.
High efficiency CMOS rectifier circuit with self-Vth-cancellation and power regulation functions for UHF RFIDs (2007)

High efficiency CMOS rectifier circuit for UHF RFID applications has been developed. The rectifier utilizes self Vth cancellation (SVC) scheme in which threshold voltage of MOSFETs is cancelled by applying gate bias voltage generated by output voltage of the rectifier itself. Very simple circuit configuration and no power dissipation feature of the scheme enable excellent power conversion efficiency (PCE) especially in small RF input power conditions. At higher RF input power conditions, PCE of the rectifier automatically decreases. This is the built-in self-power-regulation function. Proposed SVC CMOS rectifier has been fabricated with 0.35μm CMOS process and the measured performance has been compared with other types of rectifiers. The SVC CMOS rectifier achieves 29% PCE at −9.9dBm RF input power condition. This PCE is larger than ever reported rectifiers under the condition.
Evaluation of Commercial Conjugates for Fluorescent Antibody Detection of Salmonellae (1974)

Fluorescent antibody (FA) reagents for Salmonella produced by Difco, Sylvana, and Clinical Sciences, Inc., were evaluated for physicochemical and performance characteristics. The Difco panvalent (A through 064) and the Difco polyvalent (A through S) were similar in physicochemical characteristics. They had less than 60% gamma globulin with 3% albumin and had fluorescein to protein (F/P) ratios of less than 10. The Sylvana conjugate had 81% gamma globulin with less than 1% albumin. Its F/P was 33.9. The Clinical Sciences reagent contained 75% unlabeled albumin as packaged in the Fluoro-kit. Analysis of the original conjugate showed 86.5% gamma globulin with only 0.5% albumin. The (F/P) was 32.8. The performance characteristics were determined by using a variety of Enterobacteriaceae and food and feed samples. All conjugates stained the homologous Salmonella strains. The majority of cross-reactions were limited primarily to the Arizona, Citrobacter, and Escherichia coli groups. The Difco panvalent was more reactive with heterologous organisms. It stained 89% of the Arizona compared with 42% stained by the Difco polyvalent (A through S) and 39% stained by the Sylvana and Clinical Sciences reagents. We found 90% agreement between FA and culture when the Difco polyvalent was used to examine food and feed samples and 94% agreement when the Clinical Sciences Fluoro-kit was used on another group of samples.
Optimal Design of an Antenna Array for Energy Harvesting (2013)

A high-gain, linear polarized microstrip antenna array for energy harvesting at 915 MHz is studied in this letter. The optimization theory for wireless power transmission efficiency has been used to design the feeding network of the antenna array to achieve the maximum power transmission efficiency with a given antenna configuration. As a demonstration, a light emitting diode (LED) is used as the resistive load of the rectifier (a three-stage Dickson charge pump circuit) connected to the antenna array terminal. For a given input power of 10 dBm fed into a circularly polarized transmitting antenna with 6 dBi gain, the maximum distance for lighting the LED is 51 cm.

Measurement and mitigation of free convection in microfluidic gradient generators (2018)

Microfluidic gradient generators are used to study the movement of living cells, lipid vesicles, and colloidal particles in response to spatial variations in their local chemical environment. Such gradient driven motions are often slow (less than 1 μm s-1) and therefore influenced or disrupted by fluid flows accompanying the formation and maintenance of the applied gradient. Even when external flows are carefully eliminated, the solute gradient itself can drive fluid motions due to combinations of gravitational body forces and diffusioosmotic surface forces. Here, we develop a microfluid gradient generator based on the in situ formation of biopolymer membranes and quantify the fluid flows induced by steady solute gradients. The measured velocity profiles agree quantitatively with those predicted by analytical approximations of relevant hydrodynamic models. We discuss how the speed of gradient-driven flows depends on system parameters such as the gradient magnitude, the fluid viscosity, the channel dimensions, and the solute type. These results are useful in identifying and mitigating undesired flows within microfluidic gradient systems.

Low-rank approximation for FMCW automotive radar (2017)

For making car driving a much safer experience, various forms of radar systems and other object detection systems are being installed. In this paper we consider frequency-modulated continuous-wave (FMCW) automotive radar systems which collect information in so-called Range-Doppler (RD) matrices. The large amount of data collected will soon overwhelm the capacity of automotive data interfaces, and efficient data representation, and compression schemes become increasingly important for the automotive industry. To this end we propose low-rank approximation of RD matrices provided by truncated singular value decomposition. We analytically and numerically investigate error estimates for our approach. We demonstrate that low-rank approximations of RD matrices with a compression factor of over twenty still capture all essential information contained in the original RD matrix.
Display Characteristics of Example Light-Valve Projectors (1989)

Abstract : This report provides quantitative data on performance characteristics of light valve projectors in simulator displays as well as in optimal laboratory conditions. Two types of light valve projectors are discussed: a single light- valve projector (also called Talaria) and a multiple light-valve projector. The data show that (a) these projectors do not achieve brightnesses above the mesopic level in large-screen simulator displays, (b) color output includes a 'dark-field haze' which must be dealt with like ambient illumination, and (c) light/dark ratios (L/D) above 5:1 are obtainable only when the light region is white or yellow-green. Keywords: Chromaticity; Contrast; Display systems; Flight simulation; Light modulators; Light-valve projector; Luminance; Mesopic vision; Modulation transfer function; Resolution; Optical properties.
Development of micro variable optics array (2014)

This research is on the development of a micro variable optics array which employs electrowetting as the working principle. The single pixel of the array has four separated electrodes and each of them is controlled independently giving the device multi-degree of freedom. The separated electrodes are fabricated using a thick photoresist and electroplating. Several formulas showing the relation among the radius of curvature, the prism angle, and electrowetting parameters are provided. The prism angles are measured to be ±30° and compared to the calculated values. The measurement of the radius of curvature is also presented showing that the various radiuses of curvature are achievable from concave to convex.
Stabilization of a Zn(<scp>ii</scp>) hydrosulfido complex utilizing a hydrogen-bond accepting ligand (2016)

Hydrogen sulfide (H2S) has gained recent attention as an important biological analyte that interacts with bioinorganic targets. Despite this importance, stable H2S or HS(-) adducts of bioinorganic metal complexes remain rare due to the redox activity of sulfide and its propensity to form insoluble metal sulfides. We report here reversible coordination of HS(-) to Zn(didpa)Cl2, which is enabled by an intramolecular hydrogen bond between the zinc hydrosulfido product and the pendant tertiary amine of the didpa ligand.

Temporal evolution of financial-market correlations (2011)

We investigate financial market correlations using random matrix theory and principal component analysis. We use random matrix theory to demonstrate that correlation matrices of asset price changes contain structure that is incompatible with uncorrelated random price changes. We then identify the principal components of these correlation matrices and demonstrate that a small number of components accounts for a large proportion of the variability of the markets that we consider. We characterize the time-evolving relationships between the different assets by investigating the correlations between the asset price time series and principal components. Using this approach, we uncover notable changes that occurred in financial markets and identify the assets that were significantly affected by these changes. We show in particular that there was an increase in the strength of the relationships between several different markets following the 2007-2008 credit and liquidity crisis.
Parasexuality and Ploidy Change in Candida tropicalis (2013)

Candida species exhibit a variety of ploidy states and modes of sexual reproduction. Most species possess the requisite genes for sexual reproduction, recombination, and meiosis, yet only a few have been reported to undergo a complete sexual cycle including mating and sporulation. Candida albicans, the most studied Candida species and a prevalent human fungal pathogen, completes its sexual cycle via a parasexual process of concerted chromosome loss rather than a conventional meiosis. In this study, we examine ploidy changes in Candida tropicalis, a closely related species to C. albicans that was recently revealed to undergo sexual mating. C. tropicalis diploid cells mate to form tetraploid cells, and we show that these can be induced to undergo chromosome loss to regenerate diploid forms by growth on sorbose medium. The diploid products are themselves mating competent, thereby establishing a parasexual cycle in this species for the first time. Extended incubation (>120 generations) of C. tropicalis tetraploid cells under rich culture conditions also resulted in instability of the tetraploid form and a gradual reduction in ploidy back to the diploid state. The fitness levels of C. tropicalis diploid and tetraploid cells were compared, and diploid cells exhibited increased fitness relative to tetraploid cells in vitro, despite diploid and tetraploid cells having similar doubling times. Collectively, these experiments demonstrate distinct pathways by which a parasexual cycle can occur in C. tropicalis and indicate that nonmeiotic mechanisms drive ploidy changes in this prevalent human pathogen.
Transcription of the rat dopamine‐D2‐receptor gene from two promoters (1994)

Modulation of the expression of the D2-dopamine receptor gene is involved in several pathological and developmental circumstances. The gene and the corresponding promoter regions of the rat D2 receptor were isolated and partly characterized to study its regulation. The rat D2-receptor gene spans at least 50 kb, and possesses eight exons; its organization was compared to those of the other dopamine-receptor genes in a phylogenetic perspective. The gene contains two transcription-start sites: the major one is located about 320 bp upstream from the 3' end of the first exon, and a minor site is 70 bp further upstream. Transient-expression assays with fusion constructs comprising fragments of the D2-promoter region and the luciferase reporter gene confirmed the existence of two independent, TATA-lacking promoters. Both promoters separately induced transcription of the luciferase gene in C6 glioma, primary fibroblasts, GH3 and MMQ pituitary cell lines, among which only the MMQ cells normally express the D2 receptor. Transcription is enhanced by the reunion of the two promoters, and modified by the addition of upstream sequences. Thus the 1-kb promoter region analysed does not contain all the elements necessary to confer tissue-specific expression of the gene, but does carry some positive and negative regulatory elements, which remain to be characterized.
Fundamental Basis for Distance Relaying on 3-Phase Systems (1947)

In the preceding investigation the quantities upon which distance relays must depend for their operation have been determined for all possible types of faults occurring at a single location. It has been shown that the quantities obtained by the use of earlier distance relay connections for both line and ground faults do not give the closest approach to the desired result, a constant indication for all types of faults at a given location. It has been shown further that, by the use of different connections and certain auxiliary apparatus, a constant relaying indication may be obtained by the line relays for all types of line faults and by the ground relays for all types of faults involving ground, if the fault resistance is zero, and, if the fault resistance is not zero, that smaller deviations from the normal value will be obtained for a given fault resistance. The analysis has been based upon the assumptions of sine wave currents and voltages, constant circuit impedances, and negligible distributed capacitance in the faulted sections of line. It has been assumed further that the fault impedance is resistance only and that it is effectively constant throughout each cycle. All of these assumptions, except perhaps the latter, are reasonably valid as far as relaying is concerned, although some consideration must be given to the d-c component of the short-circuit currents with very high-speed relays.
A partitioned signature file structure for multiattribute and text retrieval (2002)

A partitioning method is introduced for reducing the search space required on the signature file. A partitioned signature file is better than the multilevel signature file and the S-tree in that it has an extremely small storage and processing overhead. Three partitioning schemes are outlined and their performance discussed. A description is given of the data structure necessary to support the partitioning schemes and the algorithms for signature insertion, deletion, and retrieval.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Axonal Regulation of Schwann Cell Proliferation and Survival and the Initial Events of Myelination Requires PI 3-Kinase Activity (2000)

In this report, we have investigated the signaling pathways that are activated by, and mediate the effects of, the neuregulins and axonal contact in Schwann cells. Phosphatidylinositol 3-kinase (PI 3-kinase) and mitogen-activated protein kinase kinase (MAPK kinase) are strongly activated in Schwann cells by glial growth factor (GGF), a soluble neuregulin, and by contact with neurite membranes; both kinase activities are also detected in Schwann cell-DRG neuron cocultures. Inhibition of the PI 3-kinase, but not the MAP kinase, pathway reversibly inhibited Schwann cell proliferation induced by GGF and neurites. Cultured Schwann cells undergo apoptosis after serum deprivation and can be rescued by GGF or contact with neurites; these survival effects were also blocked by inhibition of PI 3-kinase. Finally, we have examined the role of these signaling pathways in Schwann cell differentiation in cocultures. At early stages of coculture, inhibition of PI 3-kinase, but not MAPK kinase, blocked Schwann cell elongation and subsequent myelination but did not affect laminin deposition. Later, after Schwann cells established a one-to-one relationship with axons, inhibition of PI 3-kinase did not block myelin formation, but the myelin sheaths that formed were shorter, and the rate of myelin protein accumulation was markedly decreased. PI 3-kinase inhibition had no observable effect on the maintenance of myelin sheaths in mature myelinated cocultures. These results indicate that activation of PI 3-kinase by axonal factors, including the neuregulins, promotes Schwann cell proliferation and survival and implicate PI 3-kinase in the early events of myelination.
