η<sup>2</sup>-Porphyrin Ru(II) π Complexes (2010)

Highly stable eta(2)-porphyrin Ru(II) pi complexes have been synthesized. The formation of the eta(2) pi bond has been facilitated through pi-pi stacking interactions between the porphyrin and the planar ligand on Ru. pi coordination of ruthenium to porphyrin results in dramatic changes in the aromaticity and electronic properties. These properties are controllable via fine-tuning of the ligand on ruthenium.
Anomalous Source-Side Degradation of InAlN/GaN HEMTs Under High-Power Electrical Stress (2017)

The electrical degradation of InAlN/GaN high-electron-mobility transistors for millimeter-wave applications has been examined under simultaneous high V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">DS,stress</sub> and high I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Dstress</sub> electrical stress. Besides a drain current decrease and a positive threshold voltage shift, the creation of an anomalous source-side gate leakage path has been identified. We attribute this to high electric-field induced trap generation in the AlN layer directly under the gate edge on the source side. The resulting increase in gate leakage further exacerbates the degradation of the gate diode. In addition, we postulate that high-power stress leads to significant device self-heating that causes gate sinking and leads to a permanent positive threshold voltage shift and drain current degradation.
The concurrency hierarchy, and algorithms for unbounded concurrency (2001)

We study wait-free computation using (read/write) shared memory under a range of assumptions on the arrival pattern of processes. We distinguish first between bounded and infinite arrival patterns, and further distinguish these models by restricting the number of arrivals minus departures, the concurrency. Under the condition that no process takes infinitely many steps without terminating, for any finite bound k > 0, we show that bounding concurrency reveals a strict hierarchy of computational models: a model in which concurrency is bounded by k + 1 is strictly weaker than the model in which concurrency is bounded by k, for all k ≱ 1. A model in which concurrency is bounded in each run, but no bound holds for all runs, is shown to be weaker than a k-bounded model for any k. The unbounded model is shown to be weaker still—in this model, finite prefixes of runs have bounded concurrency, but runs are admitted for which no finite bound holds over all prefixes. Hence, as the concurrency grows, the set of solvable problems strictly shrinks. Nevertheless, on the positive side, we demonstrate that many interesting problems (collect, snapshot, renaming) are solvable even in the infinite arrival, unbounded concurrency model.
Technology, Productivity and Employment: An Empirical Analysis of Indian Industries (2018)

Since 2000, technology has changed at a tremendous pace and has transformed the face of industry in the entire world. Many among the top Fortune 500 companies, Amazon, Apple, Facebook, Google, Microsoft, Uber, Wal-Mart, are all technology driven and are also mainly in the services sector. While opening many new windows for investment and increase in productivity, the new technology is simultaneously disturbing the existing technological complementarities and exerting a lot of pressure on the supply of the matching skill. Many jobs which exist today would disappear tomorrow and many new jobs will get created tomorrow which do not exist today. So there is a simultaneous creation and destruction of jobs and the net impact thus depends upon their respective pace. Skill mismatches are now a common feature in all economies. While new technology is expected to increase productivity of labour and hence employment especially- in the long run, it is also simultaneously expected to displace some labour because of its very nature in the short run. A part of the explanation for the structural shift in employment in India from agriculture to services could lie in the availability and use of new technology. The present paper aims to look at the impact of technology change on labour productivity growth and employment growth for the Indian manufacturing and service industry.
Effects of Hormone Replacement Therapy on Endometrial Histology in Postmenopausal Women (1996)

At a dosage of 0.625 mg, the daily administration of CEE enhanced the development of endometrial hyperplasia. Combining CEE with cyclic or continuous MPA or cyclic MP protected the endometrium from hyperplastic changes associated with estrogen-only therapy.
Sublethal effects induced by morphine to the freshwater biological model <scp><i>D</i></scp><i>reissena polymorpha</i> (2014)

Opioids are considered as emerging contaminants in aquatic ecosystems, mainly due to their large illicit consume worldwide. Morphine (MOR) is the main opiate and it was commonly found at measurable concentrations in freshwaters. Even though its occurrence is well documented, just limited information is available regarding its hazard to nontarget organisms. The aim of this study was of the evaluation of sublethal effects induced by MOR to the freshwater bivalve Dreissena polymorpha. We exposed mussels to two MOR concentrations (0.05 µg/L and 0.5 µg/L) for 14 days and we investigated the sublethal effects by a suite of biomarkers. The Neutral Red Retention Assay (NRRA) was used as a test of cytotoxicity, while the oxidative stress was evaluated by the activity of antioxidant and detoxifying enzymes, namely catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione-S-transferase (GST), and by measuring the levels of lipid peroxidation (LPO) and protein carbonylation (PCC). The genetic damage was assessed by the Single Cell Gel Electrophoresis (SCGE) assay, the DNA diffusion assay and the micronucleus test (MN test). Finally, the filtration rate of D. polymorpha was evaluated in order to investigate possible physiological effects. Both tested concentrations reduced the lysosome membrane stability of bivalves, but only the highest MOR concentration induced significant changes in the activity of antioxidant enzymes (SOD, CAT, and GPx) and increase in lipid peroxidation levels. Slight increase in primary DNA fragmentation was noticed, while no fixed genetic damage and alterations of the filtering rate were found.
Parallel SFC/MS‐MUX screening to assess enantiomeric purity (2008)

Enantiomeric excess (ee) was evaluated for two internally synthesized compound libraries using a high-throughput automated, intelligent four-channel parallel supercritical fluid chromatography/mass spectrometry system equipped with a multiplexed ion source interface (SFC/MS-MUX). The two libraries contained compounds spanning a wide range of enantiomeric ratios with structurally diverse chemical scaffolds and stereogenic centers. The system analyzed each sample simultaneously against four chiral columns using up to six organic modifiers. Enhancements to our previously published parallel supercritical fluid chromatography/mass spectrometry system were implemented to address the challenges associated with automated trace enantiomer identification and quantitation. A reversal of enantiomer elution order was observed for several samples across multiple CSPs and modifiers. The relationship between elution order and % ee accuracy is presented for compounds exhibiting high, middle and low % ee values. Despite incidences in which the minor enantiomer eluted prior to the major enantiomer with less than baseline resolution, the overall % ee was in agreement with separations in which full baseline resolution was achieved. The methods presented here demonstrate the value and utility of high-throughput ee determinations to support drug discovery and development programs.
Outage probability analysis of dual-hop full-duplex decode-and-forward relaying over generalized multipath fading conditions (2015)

The present paper analyzes the outage probability of full-duplex (FD) regenerative relay systems over multipath fading channels. Unlike the majority of investigations that assume basic symmetric fading conditions, this analysis considers asymmetric generalized fading conditions, which are more realistic as they are encountered more often in practical wireless transmissions. To this end, it is assumed that the source-relay and source-destination links are subject to k -μ multipath fading conditions, which can represent generalized line-of-sight communication scenarios; on the contrary, the relay-to-destination link is subject to η-μ fading conditions that typically represent generalized non-line-of-sight communication scenarios. Novel analytic expressions are derived for the outage probability (OP) of the considered FD relaying system. These expressions are given in closed-form and have a relatively tractable algebraic form which renders them convenient to handle both analytically and numerically. To this effect, they are subsequently employed in analyzing the corresponding performance for various communication scenarios. It is shown that the OP of the FD relay system is, as expected, highly dependent upon the severity of fading, the relay self-interference and the interference from the direct link. Furthermore, it is shown that at relatively high average signal-to-noise ratio values, the outage probability at low fading severity and at high relay self interference outperforms the respective performance for the case of high fading severity, but with low relay self-interference. Based on this, the offered results can be useful in the design and deployment of future full-duplex based cooperative communication systems.
A Case of Clear-Cell Sarcoma (1980)

In 1965, Enzinger described a new type of a malignant soft tissue tumor under the discriptive title of “clear-cell sarcoma of tendons and aponeuroses”. This tumor was intimately bound to tendons and was composed of small nests or aggregates of round or fusiform, pale-staining cells showing prominent nucleoli.This brief paper presents the case of a 60-year-old Japanese woman with a tumor in the left knee. The histological findings of this tumor are very similar to that of Enzinger's which is above-mentioned. We, therefore, diagnosed this tumor as clear-cell sarcoma.

A New Multi-Loop Digital Control DC-DC Converter (2009)

This paper presents a new multi-loop digital control circuit which is able to detect not only the average output voltage but also the output current and input voltage of the dc-dc converter. The proposed digital control circuit consists of the three A-D converters, one DSP and the digital PWM circuit. In this proposed digital control circuit, the output voltage is used for the digital P-I-D control, the load resistance is calculated using the output voltage and current and then the moving average of the load resistance is obtained for another control loop. As a result, it is clarified that the transient time is suppressed to within 1.15ms and this result is approximately 84% smaller than the conventional static model controlled dc-dc converter. Especially, the overshoot of reactor current is suppressed to within 68% and this result is approximately 50% smaller than that of the conventional control method. It is confirmed that the proposed multi-loop control technique is useful to realize the high performance digital control circuit of dc-dc converter.
Superconductor to weak-insulator transitions in disordered tantalum nitride films (2017)

We study the two-dimensional superconductor-insulator transition (SIT) in thin films of tantalum nitride. At zero magnetic field, films can be disorder-tuned across the SIT by adjusting thickness and film stoichiometry; insulating films exhibit classical hopping transport. Superconducting films exhibit a magnetic-field-tuned SIT, whose insulating ground state at high field appears to be a quantum-corrected metal. Scaling behavior at the field-tuned SIT shows classical percolation critical exponents $z\ensuremath{\nu}\ensuremath{\approx}1.3$, with a corresponding critical field ${H}_{c}\ensuremath{\ll}{H}_{c2}$, the upper critical field. The Hall effect exhibits a crossing point near ${H}_{c}$, but with a nonuniversal critical value ${\ensuremath{\rho}}_{xy}^{c}$ comparable to the normal-state Hall resistivity. We propose that high-carrier-density metals will always exhibit this pattern of behavior at the boundary between superconducting and (trivially) insulating ground states.

Artificial retina chips as on-chip image processors and gesture-oriented interfaces (1999)

Players of a video game may sometimes find the use of conventional interfaces inappropriate. In such cases, we think that interfaces realized with a vision-based gesture recognition system may find favor. The artificial retina (AR) chip is a versatile image sensor whose use ranges from normal image acquisition to on-chip image processing, including on-chip image convolution. In this paper, we describe a gesture- input video game system, with the AR module including the AR chip, and motion-based gesture recognition algorithms. We showed that the algorithms can be accelerated by projection data, the direct output from the AR chip. To show its performance, we have applied our system to two commercially available video games.
Bioremediation of wastewater containing azo dyes through sequential anaerobic–aerobic bioreactor system and its biodiversity (2010)

Wide range of dyes and dyestuffs used in textile manufacturing are xenobiotic compounds and attract stricter to strict environmental regulations. The ability of microbial consortia to decolorize and metabolize dyes has long been known, and the use of bioremediation based technologies for treating textile wastewater has attracted interest. These dyes are decolorized by microbial consortia but technologies for their complete mineralization are still not developed. The most logical concept for the removal of azo dyes in biological wastewater treatment systems is based on anaerobic treatment, for the reductive decolorization, in combination with aerobic treatment, for the degradation of the by-products (aromatic amines) generated in the anaerobic bioreactor. Several research and review articles were published on anaerobic decolorization; however, research on complete mineralization of dyes through sequential anaerobic–aerobic bioreactors has received greater attention recently. Bioremediation through sequential anaerobic–aerobic bioreactor system has been reviewed in this article with critical appraisal using data generated through our experiments. While reviewing this work, we realized the importance of microbial diversity in a treatment unit to better understand the functional status to enhance the mineralization activity of the bioreactor.
Years of Life Lost Due to Transportation Noise and Air Pollution: a Comparative Risk Assessment for Switzerland in 2010 (2014)

Background: The health impact of noise and air pollution from rail, aircraft and road traffic is needed to estimate external costs of transport-related pollution to help policy-makers adapt road taxation schemes in Switzerland. Objective: To estimate life years lost due to transportation-related noise and air pollution in Switzerland. Methods: Spatially resolved noise and air pollution models for the year 2010 were derived for road, rail and aircraft sources. Average day-evening-night sound level (Lden) and particulate matter (PM10) were selected as indicators, and population-weighted exposures derived by traffic source. Cause-specific exposure-response functions for mortality were derived from a meta-analysis for noise and literature review for PM10. Life years lost were calculated using life table methods. Results: Burden was characterised using relative risk estimates of 1.046, 1.014 and 1.076 per 10dB increase in Lden for death from myocardial infarction, stroke and hypertension-related disease, respectively and for natural cause mortality using a relative risk estimate of 1.045 per 10µg/m3 increase in PM10. Total transport-related burden in Switzerland in 2010 amounted to 17,682 years of life lost (69% air pollution; 31% noise). Stratified by source 14,464 (82%) years of life lost were due to road, 11% to rail and 2% to aircraft traffic. Conclusions: Transport-related pollution and burden in Switzerland is dominated by air pollution from road traffic. Noise remains an important contributor to total burden, especially in relation to rail transport, since Switzerland has one of the densest rail networks in Europe which is also highly trafficked during night.

Cost-effectiveness of Clozapine in Patients With High and Low Levels of Hospital Use (1999)

This study examined the relationship between pretreatment hospital use and the cost-effectiveness of clozapine in the treatment of refractory schizophrenia.Data from a 15-site randomized clinical trial were used to compare clozapine with haloperidol in hospitalized Veterans Affairs patients with refractory schizophrenia (n = 423). Outcomes were compared among those with many days in the hospital use (hereafter, high hospital users) (n = 141; mean = 215 psychiatric hospital days in the year prior to study entry) and those with few days in the hospital use (hereafter, low hospital users) (n = 282; mean = 58 hospital days). Analyses were conducted with the full intention-to-treat sample (n = 423) and with crossovers excluded (n = 291).Clozapine treatment resulted in greater reduction in hospital use among high hospital users (35 days less than controls, P = .02) than among low users (21 days less than controls, P = .05). Patients taking clozapine also had lower health care costs; after including the costs of both medications and other health services, costs were $7134 less than for controls among high hospital users (P = .14) but only $759 less than for controls among low hospital users (P = .82). Clinical improvement in the domains of symptoms, quality of life, extrapyramidal symptoms, and a synthetic measure of multiple outcomes favored clozapine in both high and low hospital user groups.Substantial 1-year cost savings with clozapine are observed only among patients with very high hospital use prior to initiation of treatment while clinical benefits are more similar across groups. Cost-effectiveness evaluations, and particularly studies of expensive treatments, cannot be generalized across type of use groups.
Regioselective Cleavage by a Palladium(II) Aqua Complex of a Polypeptide in Different Overall Conformations (1998)

Two molecules of the complex cis-[Pd(en)(H(2)O)(2)](2+) lose aqua ligands and bind to His5 and His9 residues in the nonadecapeptide that is the carboxy-terminal segment of the protein myohemerythrin. The known modes of palladium(II)-histidine coordination are detected by (1)H NMR spectroscopy. Only the [Pd(en)(H(2)O)](2+)group bound to His5 cleaves the polypeptide backbone; the group bound to His9 does not. Only the amide bond Val3-Pro4 is cleaved. This regioselectivity is attributed to electrostatic repulsion of the [Pd(en)(H(2)O)](2+)group by cationic lysine residues 6, 7, and 10 and the absence of repulsion by the residues "upstream" from His5. The polypeptide in a partially alpha-helical conformation and the tripeptide AcGly-Gly-His, which adopts many flexible conformations, are both cleaved at the second amide bond "upstream" from the histidine residue bearing the [Pd(en)(H(2)O)](2+) group. Moreover, the rate constants for the cleavages of these two peptides are virtually the same. Regioselectivity and kinetics of the cleavage of peptides by palladium(II) aqua complexes seems to be affected by the local secondary structure in the vicinity of the scissile bond. This study is a step toward our ultimate goal-design of artificial metallopeptidases.
Thymoglobulin induction protects liver allografts from ischemia/reperfusion injury (2005)

The TG allowed for more compromised liver grafts to be transplanted with less clinical evidence of IRI and improved function. Further studies on the degree of apoptosis in the liver biopsy post-reperfusion are underway.
