Mobile Agents in Wireless LAN and Cellular Data Networks (2006)

Advancing technology in wireless communication offers users anytime, anywhere access to information and network resources without restricting them to the fixed network infrastructure. Mobile computing represents a shift in the distributed systems paradigm. The potential of decoupled and disconnected operation, location-dependent computation and communication and powerful portable computing devices gives rise to opportunities for new patterns of distributed computation that require a revised view of distributed systems. Mobile environment brings different challenges to users and service providers when compared to fixed, wired networks. Mobility brings uncertainties, as well as opportunities to provide new services and supplementary information to users in the locations where they find themselves. A mobile user is one who, on occasion, disconnects from his/her home network to change location and then reconnects, possibly using a different access technology. A necessary feature of mobility management is the ability to continue to provide system and network services to mobile users seamlessly, regardless of their location and the form of their connection. In general, most application software, operating systems and network infrastructures are intended for more conventional environments and so the mobile user has great difficulty in exploiting the computational infrastructure as fully as he/she might. The Internet Roaming solution for corporate wireless data users integrates mobile networking across private wireless local area networks (WLANs), public WLANs and cellular data networks. In this study we have developed an infrastructure using mobile agent for integrating the Wireless LAN and cellular data called Internet Roaming System (IRS). It is implemented on PMADE mobile agent system developed at IIT Roorkee.
Surface Plasmon Resonances in Diffusive Reflection Spectra of Multilayered Silver Nanocomposite Films (2008)

Ion beam mixing of silver-covered oxide films by 400 keV argon ions induces the formation of silver nanoparticles on the oxide surface. Using consecutive conformal dielectric deposition and ion beam mixing, multiple layers of the nanoparticles can be fabricated. By means of diffusive reflection and absorption spectroscopy, surface plasmon resonances of silver nanoparicles are investigated in SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> , Al <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> and TiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> films containing single and double layers of the Ag nanoparticles. We show that, compared to the extinction spectra, the diffusive reflection spectra allow clear observation of the excited plasmon modes and their modifications due to the dielectric environment and the interaction between the particles.
[Value of cardiopulmonary risk index in predicting postoperative short-term prognosis in patients with lung cancer]. (2002)

The preoperative CPRI is one of the important indexes in predicting the short-term postoperative prognosis for patients with lung cancer. However, it can not completely predict all of postoperative risks, and should be used together with other factors.
Dynamic modelling of life table data (1995)

Abstract In this paper we formulate a dynamic model expressing the human life table data by using the first‐passage‐time theory for a stochastic process. The model is derived analytically and then is applied to the mortality data in Belgium and France. A stochastic simulation is also performed for the ‘health state function’ proposed and the related stochastic paths. Furthermore the implications of the proposed model and the results derived for pension funds and option theory are discussed.
Development of Mixed Flow Cycle Absorption Heat Pump (1997)

In the field of cooling systems, due to increased demand for small and medium size cooling machines including residential use, electric power demand becomes highest in summer. This study focuses on the development and evaluation of a high efficiency absorption heat pump which can be applied to a direct gas fired, double effect system with 144㎾ nominal cooling capacity. The performance of the absorption heat pump is investigated through both cycle simulation and experiment to obtain the system characteristics with the inlet temperatures of cooling water, chilled water and gas input flow rates. The relative efficiency of the different cycles was studied. The experimental data and simulation results show that higher COP(coefficient of performance) was obtained with mixed flow cycle. Only a five percent difference in the cycle performance data was obtained from the comparison between the experiment and the cycle simulation results. As a result of this study, the optimum design conditions were determined based on the operating conditions and the COP.
A PRET microarchitecture implementation with repeatable timing and competitive performance (2012)

We contend that repeatability of execution times is crucial to the validity of testing of real-time systems. However, computer architecture designs fail to deliver repeatable timing, a consequence of aggressive techniques that improve average-case performance. This paper introduces the Precision-Timed ARM (PTARM), a precision-timed (PRET) microarchitecture implementation that exhibits repeatable execution times without sacrificing performance. The PTARM employs a repeatable thread-interleaved pipeline with an exposed memory hierarchy, including a repeatable DRAM controller. Our benchmarks show an improved throughput compared to a single-threaded in-order five-stage pipeline, given sufficient parallelism in the software.
East European Refugee Symposium (1990)

On March 29, 1990, the Centre for Refugee Studies organized a symposium at Osgoode Hall Law School, York University, to discuss the Canadian policy towards Eastern Europeans seeking to come to Canada as refugees under the current rapidly-changing circumstances. Participants were invited to express their own opinions based on their knowledge and not to represent any organizational views. Further, it was agreed that there would be no attribution of comments. Nor would the meeting be reported, though the results could be. In any case, there was no commitment by anyone to endorse the results. The intention was to encourage a free exchange of information and ideas without inhibition.
Progress on Re-generable Field Emission Cathodes for Low- Power Electric Propulsion (2007)

The research reported here explores the possibility of field-emission cathodes for use in EP that have the ability to be re-generated when the emitter tip becomes damaged. The method for re-generation takes advantage of Taylor cone formation in an effort to solidify, or quench, an operating liquid-metal-ion-source (LMIS) to preserve the sharp Taylor cone tip for use as a field-emission cathode. Electron emission I-V curves were taken after Taylor cones were formed by quenching the LMIS at different discharge currents. It is shown that quenching the LMIS at as low as 2 μA produced an increase in electron discharge current as compared with the unquenched emitter, 53 nA as compared with 25 nA at an extraction voltage of 2.7 kV. When the ion emission current at quench was increased to 3 μA and then 25 μ μ μ μA, the discharge that was measured increased to 210 nA for the 3 μA emitter and 1.02 μA for the 25 μ μ μ μA emitter at an extraction voltage of 2.7 kV. Fitting the electron emission I-V characteristics using Fowler-Nordheim theory indicated tip radii as small as 80 nm were formed during the LMIS quenching process.
The structure of the synthetic zeolite (K,Ba)*G,L (1972)

The crystal structure of the synthetic zeolite (K, Ba)-G,L, of unit cell composition K2.7 Ba7.65 [AhsShs072] .23H20, has been determined at room temperature from accurate powder data.The zeolite is hexagonal with a = 18.70A and c = 7.50A.The structure was refined to an R(I) value of 0.13 assuming space group P6/mmm.The aluminosilicate framework of (K,Ba)-G,L is very similar to that of zeolite L. However the chemical compositions of the two zeolites differ substantially, both in the Si/Al ratios and in the ions which neutralize the framework charge.Three cation positions were located but only one of these is in the main channel.Ions in the main channel are the only ones likely to exchange readily.
Severe dermatitis with loss of epidermal Langerhans cells in human and mouse zinc deficiency (2012)

Zinc deficiency can be an inherited disorder, in which case it is known as acrodermatitis enteropathica (AE), or an acquired disorder caused by low dietary intake of zinc. Even though zinc deficiency diminishes cellular and humoral immunity, patients develop immunostimulating skin inflammation. Here, we have demonstrated that despite diminished allergic contact dermatitis in mice fed a zinc-deficient (ZD) diet, irritant contact dermatitis (ICD) in these mice was more severe and prolonged than that in controls. Further, histological examination of ICD lesions in ZD mice revealed subcorneal vacuolization and epidermal pallor, histological features of AE. Consistent with the fact that ATP release from chemically injured keratinocytes serves as a causative mediator of ICD, we found that the severe ICD response in ZD mice was attenuated by local injection of soluble nucleoside triphosphate diphosphohydrolase. In addition, skin tissue from ZD mice with ICD showed increased levels of ATP, as did cultured wild-type keratinocytes treated with chemical irritants and the zinc-chelating reagent TPEN. Interestingly, numbers of epidermal Langerhans cells (LCs), which play a protective role against ATP-mediated inflammatory signals, were decreased in ZD mice as well as samples from ZD patients. These findings suggest that upon exposure to irritants, aberrant ATP release from keratinocytes and impaired LC-dependent hydrolysis of nucleotides may be important in the pathogenesis of AE.
Effects of probiotic bacteria in dogs with food responsive diarrhoea treated with an elimination diet<sup>*</sup> (2006)

We evaluated whether a probiotic supplementation in dogs with food responsive diarrhoea (FRD) has beneficial effects on intestinal cytokine patterns and on microbiota. Twenty-one client-owned dogs with FRD were presented for clinically needed duodeno- and colonoscopy and were enrolled in a prospective placebo (PL)-controlled probiotic trial. Intestinal tissue samples and faeces were collected during endoscopy. Intestinal mRNA abundance of interleukin (IL)-5, -10, -12p40 and -13, tumour necrosis factor-alpha, transforming growth factor-beta1 and interferon (IFN)-gamma were analysed and numbers of Lactobacillus spp., Bifidobacterium spp., Enterococcus spp. and Enterobacteriaceae and supplemented probiotic bacteria were determined in faeces. The Canine Inflammatory Bowel Disease Activity Index, a scoring system comprising general attitude, appetite, faecal consistency, defecation frequency, and vomitus, decreased in all dogs (p < 0.0001). Duodenal IL-10 mRNA levels decreased (p = 0.1) and colonic IFN-gamma mRNA levels increased (p = 0.08) after probiotic treatment. Numbers of Enterobacteriaceae decreased in FRD dogs receiving probiotic cocktail (FRD(PC)) and FRD dogs fed PL (FRD(PL)) during treatment (p < 0.05), numbers of Lactobacillus spp. increased in FRD(PC after) when compared with FRD(PC before) (p < 0.1). One strain of PC was detected in five of eight FRD(PC) dogs after probiotic supplementation. In conclusion, all dogs clinically improved after treatment, but cytokine patterns were not associated with the clinical features irrespective of the dietary supplementation.

Studies on the glycosylation of hydroxylysine residues during collagen biosynthesis and the subcellular localization of collagen galactosyltransferase and collagen glucosyltransferase in tendon and cartilage cells (1975)

1. The glycosylation of hydroxylysine during the biosynthesis of procollagen by embryonic chick tendon and cartilage cells was examined. When free and membrane-bound ribosomes isolated from cells labelled for 4min with [14C]lysine were assayed for hydroxy[14C]lysine and hydroxy[14C]lysine glycosides, it was found that hydroxylation took place only on membrane-bound ribosomes and that some synthesis of galactosylhydroxy[14C]lysine and glucosylgalactosylhydroxy[14C]lysine had occurred on the nascent peptides. 2. Assays of subcellular fractions isolated from tendon and cartilage cells labelled for 2h with [14C]lysine demonstrated that the glycosylation of procollagen polypeptides began in the rough endoplasmic reticulum. 14C-labelled polypeptides present in the smooth endoplasmic reticulum and Golgi fractions were glycosylated to extents almost identical with the respective secreted procollagens. 3. Assays specific for collagen galactosyltransferase and collagen glucosyltransferase are described, using as substrate chemically treated bovine anterior-lens-capsule collagen. 4. When homogenates were assayed for the collagen glycosyltransferase activities, addition of Triton X-100 (0.01%, w/v) was found to stimulate enzyme activities by up to 45%, suggesting that the enzymes were probably membrane-bound. 5. Assays of subcellular fractions obtained by differential centrifugation for collagen galactosyltransferase activity indicated the specific activity to be highest in the microsomal fractions. Similar results were obtained for collagen glucosyltransferase activity. 6. When submicrosomal fractions obtained by discontinuous-sucrose-density-gradient-centrifugation procedures were assayed for these enzymic activities, the collagen galactosyltransferase was found to be distributed in the approximate ratio 7:3 between rough and smooth endoplasmic reticulum of both cell types. Similar determinations of collagen glucosyltransferase indicated a distribution in the approximate ratio 3:2 between rough and smooth microsomal fractions. 7. Assays of subcellular fractions for the plasma-membrane marker 5′-nucleotidase revealed a distribution markedly different from the distributions obtained for the collagen glycosyltransferase. 8. The studies described here demonstrate that glycosylation occurs early in the intracellular processing of procollagen polypeptides rather than at the plasma membrane, as was previously suggested.
Amino-acid site variability among natural and designed proteins (2013)

Computational protein design attempts to create protein sequences that fold stably into pre-specified structures. Here we compare alignments of designed proteins to alignments of natural proteins and assess how closely designed sequences recapitulate patterns of sequence variation found in natural protein sequences. We design proteins using RosettaDesign, and we evaluate both fixed-backbone designs and variable-backbone designs with different amounts of backbone flexibility. We find that proteins designed with a fixed backbone tend to underestimate the amount of site variability observed in natural proteins while proteins designed with an intermediate amount of backbone flexibility result in more realistic site variability. Further, the correlation between solvent exposure and site variability in designed proteins is lower than that in natural proteins. This finding suggests that site variability is too uniform across different solvent exposure states (i.e., buried residues are too variable or exposed residues too conserved). When comparing the amino acid frequencies in the designed proteins with those in natural proteins we find that in the designed proteins hydrophobic residues are underrepresented in the core. From these results we conclude that intermediate backbone flexibility during design results in more accurate protein design and that either scoring functions or backbone sampling methods require further improvement to accurately replicate structural constraints on site variability.
Treatment of Colored Effluents with Lignin-Degrading Enzymes: An Emerging Role of Marine-Derived Fungi (2008)

Some of the industries that discharge highly colored effluents are paper and pulp mills, textiles and dye-making industries, alcohol distilleries, and leather industries. Terrestrial white-rot basidiomycetous fungi and their lignin-degrading enzymes laccase, manganese-peroxidase and lignin peroxidases are useful in the treatment of colored industrial effluents and other xenobiotics. Free mycelia, mycelial pellets, immobilized fungi or their lignin-degrading enzymes from terrestrial fungi have been reported in treatment of several effluents. Marine obligate or facultative (marine-derived) fungi may have unique properties but have not been explored sufficiently for this purpose. This article presents a critical review of bioremediation potential of such fungi and their lignin-degrading enzymes in comparison with the state-of-the-art in terrestrial white-rot fungi.
A Novel Interactive Streaming Protocol for Image-Based 3D Virtual Environment Navigation (2009)

Image-based rendering (IBR) has attracted recent attention mainly due to its low requirements for generating new scenes based on a sequence of reference images. IBR has paved the way for a new class of application, the free viewpoint television (FTV), which allows the viewer to interactively control the camera and move freely within a scene. IBR can also be used to render complex 3D virtual environments on graphics-constrained devices, such as cellphones and PDAs. In this paper, we propose a new protocol that offers the user a richer virtual experience by pre-streaming the necessary imagery data to generate new views as the user wanders within a 3D environment. We introduce the idea of key partial panoramas, Le., panorama segments that cover movements in any direction by simply strafing from an appropriate key partial panorama and streaming the amount of lost pixels. We have implemented our protocols and evaluated them against two well-known approaches. Experimental results show that our solution outperforms the selected approaches, by minimizing the delay between image updates and by allowing for a more complex navigation scheme.
Large wavelength shifts in thin p-clad InGaAs QW lasers (2002)

Summary form only given. In our work with thin upper cladding layer InGaAs single quantum well (SQW) lasers, we have found that shifts of greater than 50 nm can be achieved by simply changing the type of metal used on the p-GaAs heavily doped contact layer adjacent to the thin p-clad layer. In this report, we describe how changes in optical mode loss are responsible for the large wavelength shifts observed.

Combined Treatment With Valsartan and Spironolactone Prevents Cardiovascular Remodeling in Renovascular Hypertensive Rats (2006)

Treatment with an angiotensin blocker (ARB) and an aldosterone blocker has been shown to have beneficial effects on cardiac remodeling in several cardiac diseases. It is still not clear whether the combination of these drugs is more effective against cardiac remodeling than the use of either agent alone. We examined the effects of combined treatment with valsartan, an ARB, and spironolactone, an aldosterone blocker, on cardiac remodeling in the renovascular hypertensive (RHT) rat. The RHT rats were divided into 4 groups administered valsartan (3 mg/kg/day, ARB group), spironolactone (4 mg/kg/day, SPRL group), both drugs at these doses (combined group), or neither drug (untreated RHT group). After 5 weeks, systolic blood pressure was significantly reduced in the 3 treatment groups, however, there were no significant differences in the extent of blood pressure reduction among the 3 treatment groups. The heart weight/body weight ratio in each of the 3 treatment groups was significantly lower than that in the untreated RHT group. The degree of cardiac and perivascular fibrosis in the SPRL group and the combined group were significantly lower than that in the untreated RHT group. Myocyte remodeling in the ARB group and in the combined group was significantly smaller than that in the untreated RHT group. These results suggest that SPRL treatment prevents cardiac and perivascular fibrosis and ARB treatment suppresses the cellular hypertrophy of myocytes, and that, therefore, combined treatment with both drugs prevents cardiac remodeling by acting against both myocyte hypertrophy and cardiac fibrosis in RHT rats.
Properties of metK Mutants of Escherichia coli K-12 (1973)

Some of the properties of three metK mutants of Escherichia coli K-12 have been examined. All three strains have lower than normal levels of SAM (S-adenosyl-l-methionine) synthetase and elevated levels of cystathionine synthetase and cystathionase. One strain (RG73) appears to have an unstable SAM synthetase, suggesting that it carries a structural gene mutation. The two strains (RG62 and RG109) which have the lowest levels of SAM synthetase when grown on minimal medium have appreciably higher levels of enzyme when grown on complete medium. Growth on defined media supplemented with leucine or methionine causes a several-fold increase in the specific activity of SAM synthetase with associated decreases in cystathionine synthetase and cystathionase, but the changes are not as large as those seen in cells grown on LB broth. The SAM pools of strains RG62 and RG109 are markedly lower than normal while that of strain RG73 is slightly below normal. The methionine pools of all three strains are elevated several-fold. The metK strains are able to synthesize cyclopropane fatty acids, but the rate of their formation is slowed. Modification and restriction of phage 21 appears to be normal, suggesting that these strains are able to methylate DNA.
Targeting Intraocular Neovascularization and Edema — One Drop at a Time (2008)

Topical application of inhibitors of growth factor receptors or their signaling pathways protects against choroidal neovascularization, vascular leakage, and retinal edema in mice.
3D VQI: 3D Visual Query Interface (2009)

The 3D Visual Query Interface (3D VQI) is a Web-based database application that allows for shape-based searches in addition to more traditional text-based queries of the 3D vessel dataset. This interface allows researchers remote access to vessel collection that can be analyzed from anywhere in the world. The interface is divided into two sections with right half supporting the ability to draw profile curve both symmetric and asymmetric. This query can be further refined using the left half which provides contextual based information. Using a curve-matching algorithm the software then searches the database and returns a series of potential matches sorted by the percentage of similarity between the curves. Each match can then be selected for more detailed viewing of the 3D model and data or for further analysis.
