Protective effect of Withania somnifera dunal root extract against protracted social isolation induced behavior in rats. (2008)

This study investigated the effect of Withania somnifera Dunal (WS) root extract and diazepam in social isolation induced behavior such as anxiety and depression in rats. Rats were isolated for 6 weeks and the assessment of changed behavior were done on elevated plus maze (EPM) and forced swim test (FST). Isolation reared rats spent less time into the open arms on EPM and significantly increased immobility time in FST compared to group housed rats. WS (100, 200 or 500 mg/kg, oral) and diazepam (1 or 2 mg/kg, ip) dose dependently increased the time spent and entries into the open arms on EPM test and showed the anxiolytic activity. Subeffective dose of WS (50 mg/kg, oral) potentiated the anxiolytic action of diazepam (0.5, 1 or 2 mg/kg, ip). WS (100, 200 or 500 mg/kg, oral) also reduced the immobility time in FST, thus showed antidepressant effect in both group housed and social isolates. The investigations support the use of WS as a mood stabilizer in socially isolation behavior in Ayurveda.
Spectral and temporal resolution of recombination from multiple excitation states in modulation-doped AlGaN∕GaN multiple quantum well heterostructures (2005)

Time-resolved photoluminescence measurements of carrier lifetimes in modulation-doped (100Å)AlxGa1−xN∕(100Å)GaN multiple quantum well heterostructures are reported. The photoluminescence (PL) spectrum exhibits several lines associated with recombination of carriers from multiple excited electron states to the hole ground state. The PL decay times associated with ground state recombination, e0h0, are found to be much longer than the inverse repetition rate of our system (20μs) and estimated to be 9 ms. The experimental lifetimes associated with carrier recombination from excited states vary between 4μs for the first excited state, e1h0, and 4.5 ns for the fourth excited state, e4h0. These lifetimes are in very good agreement with a self-consistent calculation of radiative recombination lifetimes which takes into account piezoelectric and spontaneous polarization. The significant differences in recombination lifetimes are the result of the large built-in electric field in the wells (0.5MV∕cm).
Prediction of Suicidal Behavior in Clinical Research by Lifetime Suicidal Ideation and Behavior Ascertained by the Electronic Columbia-Suicide Severity Rating Scale (2013)

Patients reporting lifetime suicidal ideation with intent to act and/or prior suicidal behavior at baseline are 4 to 9 times more likely to prospectively report suicidal behavior during study participation.
4D DMLC leaf sequencing to minimize organ at risk dose in moving anatomy (2007)

The most favorable treatment for moving body anatomy should aim at utilizing organ motion to minimize the dose to sensitive structures without compromising the dose delivered to the target. The solution of the problem of appropriate intensity redistribution over different phases of body motion is achievable in dynamic multileaf collimator (DMLC) intensity modulated radiation therapy delivery, due to the fact that multiple solutions are admissible for imposing the same intensity map over a moving target in this technique of irradiation. The realization of this type of delivery provides a treatment methodology that delivers treatment plans for moving patient anatomy that are superior to any treatments possible for static patient body anatomy. This paper is devoted to exploring this idea. To this end, a simple, though clinically realistic example is developed and presented that shows modified DMLC leaf motions that deliver a predetermined intensity to a moving target while reducing the dose delivered to organs at risk.
PARTIAL PURIFICATION AND PROPERTIES OFANGIOTENSIN I CONVERTING ENZYME FROM RABBIT PLASMA (1971)

Angiotensin I converting enzyme was purified from rabbit plasma by means of ammonium sulfate fractionation, DEAE-Sephadex A-50 column chromatography and Sephadex G-200 gel filtration. The purified material was separated from angiotensinase, carboxypeptidase and L-leucyl-β-naphthylamidase, but could not be separated from di- or tri-peptidases. The specific activity of the enzyme was elevated 63 fold by the purification method. The purified material produced angiotensin II, His-Leu, histidine and leucine when incubated with angiotensin I at 37°C, pH 7.2 for 20 hours. This fact suggests that the enzyme hydrolyses the Phe-His bond of angiotensin I. The enzyme activity was inhibited by the addition of 10-3M EDTA. Optimum pH of the enzyme was about pH 7.2.
Harvesting Triplet Excitons from Fluorescent Blue Emitters in White Organic Light‐Emitting Diodes (2007)

A novel concept for white organic light emitting diodes (OLEDs) enabling the utilization of all electrically generated excitons for light generation is introduced. The key feature is a fluorescent blue emitter with high triplet energy, rendering it possible to harvest its triplet excitons by letting them diffuse to an orange phosphorescent iridium complex.
Characterization of exceptionally thermostable single-stranded DNA-binding proteins from Thermotoga maritima and Thermotoga neapolitana (2010)

The results showed that TmaSSB and TneSSB are the most thermostable SSB proteins identified to date, offering an attractive alternative to TaqSSB and TthSSB in molecular biology applications, especially with using high temperature e. g. polymerase chain reaction (PCR).
A Possible Chromatic Correction System for Electron Lenses (1955)

It is shown that a suitably arranged group of four electrodes has properties which make it a useful integral part of a system for the correction of axial chromatic aberration. Its application to the correction system proposed by Scherzer, and to a new simplified system having certain advantages over that of Scherzer is discussed. Curves are given for the chromatic and focal properties of the corrective electrode group, and an example of a corrective system is considered numerically. The effect of this system on off-axial chromatic aberration is investigated, and the possibility of combining it with a system for spherical correction is envisaged.
Further Bioactive Piperidine Alkaloids from the Flowers and Green Fruits of <i>Cassia </i><i>s</i><i>pectabilis</i> (2004)

The flowers of Cassia spectabilis yielded three new piperidine alkaloids, (-)-3-O-acetylspectaline (1), (-)-7-hydroxyspectaline (2), and iso-6-spectaline (3), together with the known (-)-spectaline (4). The green fruits of this plant were also investigated, resulting in the isolation of 1 and 4. Their structures were elucidated using a combination of multidimensional NMR and MS techniques, and relative stereochemistries were established by NOESY correlations and analysis of coupling constants. The DNA-damaging activity of these compounds was evaluated using a mutant yeast, Saccharomyces cerevisiae, assay.
Toughening through multilayering in TiN–AlTiN films (2007)

The damage response of columnar multilayers of TiN and AlTiN to Vickers indentation is studied through focused ion beam machining and elastic modelling. Multilayers display an enhanced resistance, which increases with layer refinement, to the multiple fracture modes that appear at high loads in these materials, including edge (nested) cracks and inclined shear cracks. Measurements of layer thickness reveal that multilayers display additional modes of plastic deformation that lead to permanent compression and bending of the film. An elastic model of contact deformation in a bilayer where plasticity is mimicked by greatly enhanced elastic compliance of the film is used to rationalize the trends in crack resistance. It is shown that the enhanced toughness is not due to any increase in the strain capacity (hardness/modulus) of the film material, brought about by multilayering.
Wavelength-spacing tunable multiwavelength erbium-doped fiber laser based on four-wave mixing of dispersion-shifted fiber (2006)

We experimentally demonstrate a wavelength-spacing tunable multiwavelength erbium-doped fiber laser based on degenerate four-wave mixing in a dispersion-shifted fiber incorporating multiple-fiber Bragg gratings. We have achieved stable operation of the multiwavelength erbium-doped fiber laser, which has 0.8 nm spacing ten-channel lasing wavelengths and a high extinction ratio of more than ∼45 dB, at room temperature. The output power of the multiwavelength erbium-doped fiber laser is stable, so the peak fluctuation is less than ∼0.2 dB. By changing the properties such as loss and polarization state of multiple fiber Bragg grating cavities, we can exercise flexible control of the wavelength spacing of the multiwavelength output. We can also obtain switchable multiwavelength lasing operation by elimination of the effects of alternate single-fiber Bragg gratings.
Early-Onset Aging and Defective DNA Damage Response in <i>Cdc14b</i>-Deficient Mice (2011)

The Cdc14 dual-specificity phosphatase plays a key role in the mitotic exit of budding yeast cells. Mammals have two homologues, Cdc14a and Cdc14b. Unlike the yeast counterpart, neither Cdc14a nor Cdc14b seems to be essential for mitotic exit. To determine the physiological function of Cdc14b, we generated mice deficient in the phosphatase. The mutant mice were viable and did not display overt abnormalities. However, these mice developed signs of aging at much younger ages than the wild-type mice. At the cellular level, the Cdc14b-deficient mouse embryonic fibroblasts (MEFs) grew more slowly than the controls at later passages as a result of increased rates of senescence. Consistent with these premature-aging phenotypes, Cdc14b-deficient cells accumulated more endogenous DNA damage than the wild-type cells, and more Cdc14b-deficient MEFs entered senescence than control MEFs in response to exogenous DNA damage. However, no deficiencies in DNA damage checkpoint response were detected in Cdc14b mutant cells, suggesting that the function of Cdc14b is required for efficient DNA damage repair.
Numerical Simulation of Coughed Droplets in the Air-Conditioning Room (2015)

Abstract The public pay close attention to infectious disease transmission in the indoor environments since the outbreak of severe acute respiratory infectious diseases. This paper studies the spatial distribution and temporal evolution of coughed droplets with the size of 10 μm in the air-conditioning room of two ventilation patterns, specifically mixing ventilation (MV) and displacement ventilation (DV). There are two people standing face to face with a distance of 0.5m, 0.75m and 1m. RNG k-ɛ turbulent model is used to simulate indoor airflow. The diffusion, gravitational settling and deposition mechanism of coughed droplets matter are simulated by using Lagrangian method. The simulation results indicate that the temperature is uniform in MV, while it is not in DV. DV is easier to discharge the coughed droplets and reduce infection rates. The closer distance between human bodies can increase infection rates.
Alternatives in cellular system design for serving portables (1984)

System design alternatives for serving low-power hand-held portable radiotelephones in cellular systems are explored. Two popular designs are considered for systems with little or no frequency reuse. In one design, omnidirectional antennas are used with full-coverage space diversity and receivers with high sensitivity. In the other design, 60-degree sector receive antennas are used with sectorized space diversity. Although both designs are able to compensate for the low radiated power (0.6 watts) of hand-held portables, the more complex sectorized scheme shows somewhat greater variability in service quality because it combines signals from antennas looking into different sectors. With both methods, quality in the portable-to-land direction will generally be better than quality in the land-to-portable direction despite the low radiated power of the portable. The major difficulty with serving portables in systems that have significant frequency reuse is co-channel interference. Cell sectorization, RF power balancing, and dynamic RF power control are needed to control interference and allow portables and vehicular mobiles to operate on the same set of channels. Diversity combining arrangements at the cell site that provide full diversity coverage over the serving sector (i.e., two antennas per sector) offer better protection against interference than do those that combine signals coming from antennas that are looking into different sectors. With the latter arrangement, the full benefit of cell sectorization cannot be realized since the cell-site receiver is susceptible to interference coming into adjacent sector antennas as well as interference coming into the serving sector antenna.
Studies in the chemistry of technetium. Complexes of technetium-(II), -(III), and -(IV) with 1,2-bis(diphenylphosphino)ethane (1970)

Complexes of bi-and ter-valent technetium have been prepared with the diphosphine 1,2-bis(diphenylphosphino)ethane, viz. [Tc(diphos)2X2] and [Tc(di-phos)2Br2]Br where X = CL, Br. The complexes can be formulated as octahedral compounds and both magnetic and spectral evidence agree with this. The quadrivalent technetium compounds TcBr4, TcBr4(Ph3P)2, and the salts (diphos-H2)TcX6(X = CL, Br) and Ag2TcCl6 have also been prepared and are described. Attempts to prepare the trichloride (TcCL3) are also reported.
Multisolvent Successive Extractive Refining of Coal (1996)

Abstract A selected group of commercial solvents, namely, anthracene oil (AO), ethylenediamine (EDA), and liquid paraffin (LP), were used for successive extraction of Assam coal. Hot AO provided a wide range of mixed solvents that dissociate chemically and interact favorably with dissociated and undissociated coal macro-molecules (“like dissolves like”). This resulted to the enhancement of the EDA extractability of the AO-pretreated residual coal. EDA is a good swelling solvent and results in physical dissociation of coal molecules. The residual coal obtained after EDA extraction was subjected to extraction with LP, an H-donor, high-boiling (330°-360°C) solvent. LP thermally dissociates coal macromolecules and interacts with the coal at its plastic stage at the free radical pockets. The mechanism and molecular dynamics of the multisolvent successive extraction of Assam coal using AO-EDA-LP solvents are discussed. In early attempts, successive extractions did not modify the extraction yield in the single solvent showing the maximum extraction. However, the AO-EDA-LP extraction resulted in the extraction of 70% coal, more than for any of the individual solvents used. Therefore, AO-EDA-LP extraction of coal affords a process yielding a superclean, high-heating value fuel from coal under milder conditions. Several uses of superclean coal have been recommended. Present studies have revealed a new concept concerning the structure of coal having 30% polyaromatic condensed entangled rings and 70% triaromatic-heterocyclic-naphthenic-aliphatic structure. The insolubility of coal is due to the polyfunctional-hetero-cyclic-condensed structure having a polyaromatic core with intermacromolecular entanglements.
<i>cis</i>- and<i>trans</i>-Linalool 3,7-Oxides and Methyl Salicylate Glycosides and (<i>Z</i>)-3-Hexenyl<i>β</i>-<scp>D</scp>-Glucopyranoside as Aroma Precursors from Tea Leaves for Oolong Tea (1996)

Two new alcoholic aroma precursors, cis- and trans-linalool, 3,7-oxides 6-O-beta-D-apiofuranosyl-beta-D-glucopyranosides (1 and 2), as well as two already known compounds, (Z)-3-hexenyl beta-D-glucopyranoside (3) and methyl salicylate 6-O-beta-D-xylopyranosyl-beta-D-glucopyranoside (beta-primeveroside: 4), and another new monoterpendiol glycoside, 8-hydroxygeranyl beta-primeveroside (5) have recently been isolated as aroma precursors in tea leaves (Camellia sinensis var. sinensis cv. Maoxie) ready for oolong tea processing.
Multifunctional Trackable Dendritic Scaffolds and Delivery Agents (2011)

Dual action: Trackable multifunctional dendritic scaffolds with high internal loading capacity were synthesized based on a PEG core. Orthogonal functionalization of chain-end and internal groups allowed the dendrimers to be both labeled and loaded with releasable dyes for simultaneous monitoring of the dendritic carrier and release of the dye payload inside living cells (see picture).

An Experimental Study of Bitmap Compression vs. Inverted List Compression (2017)

Bitmap compression has been studied extensively in the database area and many efficient compression schemes were proposed, e.g., BBC, WAH, EWAH, and Roaring. Inverted list compression is also a well-studied topic in the information retrieval community and many inverted list compression algorithms were developed as well, e.g., VB, PforDelta, GroupVB, Simple8b, and SIMDPforDelta. We observe that they essentially solve the same problem, i.e., how to store a collection of sorted integers with as few as possible bits and support query processing as fast as possible. Due to historical reasons, bitmap compression and inverted list compression were developed as two separated lines of research in the database area and information retrieval area. Thus, a natural question is: Which one is better between bitmap compression and inverted list compression?

Simultaneous measurement of cocaine, cocaethylene, their metabolites, and "crack" pyrolysis products by gas chromatography-mass spectrometry (1994)

We developed a sensitive and specific assay for the simultaneous measurement of cocaine, cocaethylene, six of their metabolites, and anhydroecgonine methyl ester, a pyrolysis product, in biological fluids. The assay involves solid-phase extraction columns containing a copolymeric bonded phase for isolation of cocaine analytes, derivatization with N,O-bis(trimethylsilyl)trifluoroacetamide and 10 g/L trimethylchlorosilane, and measurement with gas chromatography-mass spectrometry operating in the selected-ion monitoring mode. Detector responses for analytes were linear over a concentration range of 3.1-1000 micrograms/L. The limits of detection were approximately 1 microgram/L for cocaine, ecgonine methyl ester, and benzoylecgonine and 3-6 micrograms/L for the remaining analytes. Hydrolysis of cocaine and artifact formation of anhydroecogonine methyl ester during extraction and assay was < 1%. Cocaine and its derivatives appear in different proportions in plasma, saliva, and urine according to the biological fluid and time of measurement. Each biological fluid provides unique information on the disposition of cocaine in human subjects.
Probation Practice and an End to Punishment (1990)

On prudential and moral grounds, it is argued, the rehabilitation of offenders should be restored as the central philosophical ideal of the probation service. The paper discusses how and why this might be done, and suggests how it might modify current probation practice and its regulation.
Fast digital recording of X-ray dilution curves: a preliminary evaluation. (1982)

A digital radiography apparatus that is implemented on a computed tomography (CT) scanner allows for the fast recording of dilution curves of thin sections of a CT scan. Densities are plotted vs. time, and structures can be allocated by reference to the corresponding CT image. Intravenous bolus passage in the larger vessels, and enhancement in the organs was determined in patients. Modulations that resulted from breathing posed problems, but those that resulted from pulsation may yield useful additional information. Possible clinical applications are discussed.
Inulin-type fructans of longer degree of polymerization exert more pronounced in vitro prebiotic effects (2006)

Its slower fermentation rate and higher prebiotic potency makes inulin a more interesting compound than oligofructose to beneficially influence the microbial community from both the proximal and distal colon regions.
