Structural and Electrical Properties of NASICON Type Solid Electrolyte Nanoscaled Glass-Ceramic Powder by Mechanical Milling for Thin Film Batteries (2013)

During last two decades, lithium-based glasses have been studied extensively as electrolytes for solid-state secondary batteries. For practical use, solid electrolyte must have high ionic conductivity as well as chemical, thermal and electrochemical stability. Recent progresses have focused on glass electrolytes due to advantages over crystalline solid. Glass electrolytes are generally classified into two types oxide glass and sulfide glass. Oxide glasses do not react with electrode materials and this chemical inertness is advantageous for cycle performances of battery. In this study, major effort has been focused on the improvement of the ion conductivity of nanosized LiAlTi(PO4)3 oxide electrolyte prepared by mechanical milling (MM) method. After heating at 1000 degrees C the material shows good crystallinity and ionic conductivity with low electronic conductivity. In LiTi2(PO4)3, Ti4+ ions are partially substituted by Al3+ ions by heat-treatment of Li20-Al2O3-TiO2-P2O5 glasses at 1000 degrees C for 10 h. The conductivity of this material is 1.09 x 10(-3) S/cm at room temp. The glass-ceramics show fast ion conduction and low E(a) value. It is suggested that high conductivity, easy fabrication and low cost make this glass-ceramics promising to be used as inorganic solid electrolyte for all-solid-state Li rechargeable batteries.
Use of Polyoxetane Resin-Supported Quaternary Onium Salts as a Polymeric Phase-Transfer Catalyst for Preparing Ethers from Hydroxy Compounds and Alkyl Halides (1989)

Abstract As a polymer support for preparing polymeric phase-transfer catalysts (PTC), soft, moderately polar polyoxetane resins were employed which were synthesized by a cationic ring-opening copolymerization of oxetanes Br(CH2)nOCH2–X with bisoxetanes X–CH2O(CH2)nOCH2–X, where X=3-methyl-3-oxetanyl and n=4 or 6. In a few cases of those polymerizations, 3-(2-oxadecyl)-3-methyloxetane was used as a comonomer with a lipophilic pendant. The terminal bromine of the pendant groups of such polyoxetane resins was quaternized with tributylamine or tributylphosphine in DMF in order to examine the phase-transfer catalyzing ability of the resultant quaternary onium bromides in the etherification reaction between alkyl halides and alcohols or phenols. These reactions gave the desired products in fairly good yields within reaction periods of 1–3 h, indicating that the catalytic activities of those PTCs are comparable to that of tetrabutylammonium bromide. A fairly high catalytic activity of the polymeric PTC was observed at each of ten stages in a process using the polymeric PTC repeatedly for the etherification reaction of 3-hydroxymethyl-3-methyloxetane with 1,4-dibromobutane.
Scattering and absorption characteristics of lossy dielectric, chiral, nonspherical objects (1985)

A procedure based on the T-matrix method is devised to study the electromagnetic response of chiral, (lossy) dielectric, nonspherical objects exposed to an arbitrary incident field. Reductions in the method for axisymmetric objects are discussed. Using the technique thus developed, the plane wave scattering and absorption characteristics of lossy dielectric, axisymmetric scatterers (spheres as well as prolate and oblate spheroids), with and without chiral properties, are examined at frequencies above 50 GHz. The relative permittivity of the objects is assumed to be frequency dependent, whereas the chiral parameters are set to be constant in the numerical study. From the computed results, it appears that chiral spheres are the most effective objects in retarding the progress of an incident plane wave regardless of its polarization.
Capacity Planning as a Service for Enterprise Standard Software (2017)

Too often, capacity planning activities that are crucial to software performance are being pushed to late development phases where trivial measurement-based assessment techniques can be employed on enterprise applications that are nearing completion. This procedure is highly inefficient, time consuming, and may result in disproportionately high correction costs to meet existing service level agreements. However, enterprise applications nowadays excessively make use of standard software that is shipped by large software vendors to a wide range of customers. Therefore, an application similar to the one whose capacity is being planned may already be in production state and constantly produce log data as part of application performance monitoring facilities. In this paper, we demonstrate how potential capacity planning service providers can leverage the dissemination effects of standard software by applying machine learning techniques on measurement data from various running enterprise applications. Utilizing prediction models that were trained on a large scale of monitoring data enables cost-efficient measurement-based prediction techniques to be used in early design phases. Therefore, we integrate knowledge discovery activities into wellknown capacity planning steps, which we adapt to the special characteristics of enterprise applications. We evaluate the feasibility of the modeled process using measurement data from more than 1,800 productively running enterprise applications in order to predict the response time of a widely used standard business transaction. Based on the trained model, we demonstrate how to simulate and analyze future workload scenarios. Using a Pareto approach, we were able to identify cost-effective design alternatives for a planned enterprise application.
Deletion mutants of simian virus 40 defective in biosynthesis of late viral mRNA. (1979)

Deletion mutants of simian virus 40 defective in late gene functions have been examined for genetic elements that control the biosynthesis of the viral mRNAs. Mutant-specific RNA from infected cells was identified by CH3Hg/(OH)/agarose gel electrophoresis and mapped by the nuclease S1 technique. Altered RNA species, shortened by a size equivalent to the deletion region, can be detected in cells infected with these mutants lacking sequences within the body RNA segments. On the other hand, mutants that lack the 5'-end of the body sequences (a splice junction) fail to accumulate the respective shortened RNA species. In particular, mutant dl-2301 whose deletion includes both the leader and body splice junctions plus the intervening sequences, exhibits a polar effect on a distal gene. Whereas the late region of dl-2301 can be transcribed normally, the mutant defect appears to be associated with little or no accumulation of the mutant-specific late RNA in the infected cells. These results suggest that splice junctions or the intervening sequences, or both, in the viral genome are control signals for post-transcriptional processing of the viral RNA.

Bilirubin/Albumin Ratio for Predicting Acute Bilirubin-induced Neurologic Dysfunction. (2011)

Based on our results, we suggest using B/A ratio in conjunction with TSB. This can improve the specificity and prevent unnecessary invasive therapy such as exchange transfusion in icteric neonates.

Two-Dimensional Gas Chromatography Analysis of Components in Fuel and Fuel Additives Using a Simplified Heart-Cutting GC System (2003)

Multidimensional gas chromatography (MGC) using heart cutting is an old idea that can benefit from the performance of modern instruments and capillary columns to provide fast, reliable separation of target analytes from complex sample matrices. A simplified heart-cutting switch is described that uses these improvements to provide very narrow precise heart cuts between columns of different selectivity. This system is used to analyze ppm levels of 4,6-dimethydibenzothiophene in diesel fuel using a standard flame ionization detector instead of a complex sulfur-selective detector. MGC systems also offer the possibility of faster analysis speed by using two short columns of different selectivity instead of very long columns to resolve compounds from complex matrices. The analysis of alcohols in denatured fuel ethanol using the MGC system is performed over six times faster than the standard American Society for Testing and Materials methodology.
Corrosion behavior of Hastelloy-N alloys in molten salt fluoride in Ar gas or in air (2015)

The effects of air on the corrosion of Hastelloy-N alloys in molten salt coolant containing fission product elements were investigated to determine the safety of structural materials in high-temperature reactors cooled with fluoride salt. Corrosion tests of Hastelloy-N in the molten fluoride salt FLiNaK in an alumina crucible and a graphite crucible under argon gas or air were performed at 773–923 K for 100 h. The depth of corrosive attack, as well as the extent of chromium and molybdenum depletion, increased with increasing temperature. The extent of Hastelloy-N corrosion in molten salt under air was significantly greater than under argon gas. The effect of adding the impurity cesium iodide to molten salt containing nuclear waste fuel on the corrosion behavior was negligible.
Aerosol vaccination with Bacille Calmette-Guerin induces a trained innate immune phenotype in calves (2019)

Mycobacterium bovis Bacillus Calmette-Guérin (BCG) is a live attenuated vaccine for use against tuberculosis (TB); however, it is known to reduce childhood mortality from infections other than TB. The unspecific protection induced by BCG vaccination has been associated with the induction of memory-like traits of the innate immune system identified as 'trained' immunity. In humans and mouse models, in vitro and in vivo BCG training leads to enhanced production of monocyte-derived proinflammatory cytokines in response to secondary unrelated bacterial and fungal pathogens. While BCG has been studied extensively for its ability to induce innate training in humans and mouse models, BCG's nonspecific protective effects have not been defined in agricultural species. Here, we show that in vitro BCG training induces a functional change in bovine monocytes, characterized by increased transcription of proinflammatory cytokines upon restimulation with the toll-like receptor agonists. Importantly, in vivo, aerosol BCG vaccination in young calves also induced a 'trained' phenotype in circulating peripheral blood mononuclear cells (PBMCs), that lead to a significantly enhanced TLR-induced proinflammatory cytokine response and changes in cellular metabolism compared to PBMCs from unvaccinated control calves. Similar to the long-term training effects of BCG reported in humans, our results suggest that in young calves, the effects of BCG induced innate training can last for at least 3 months in circulating immune populations. Interestingly, however, aerosol BCG vaccination did not 'train' the innate immune response at the mucosal level, as alveolar macrophages from aerosol BCG vaccinated calves did not mount an enhanced inflammatory response to secondary stimulation, compared to cells isolated from control calves. Together, our results suggest that, like mice and humans, the innate immune system of calves can be 'trained'; and that BCG vaccination could be used as an immunomodulatory strategy to reduce disease burden in juvenile food animals before the adaptive immune system has fully matured.
Fluorometric determination of indocyanine green in plasma. (1987)

With this fluorometric method for measuring indocyanine green (ICG) in biological fluids, the limit of detection is an order of magnitude lower than for the traditional spectrophotometric procedure. The excitation and emission maxima are 780 and 810 nm, respectively. Agreement was excellent (r = 0.998) between direct results by this method and those by a liquid-chromatographic procedure with spectrophotometric detection. ICG breaks down in aqueous solution; the degradation products can be detected with liquid-chromatographic/spectrophotometric methods, but because the metabolites are not fluorescent, they do not interfere in the method present here. The increased specificity and sensitivity of this method should permit much more complete analysis of the kinetics of ICG disposition.
Self-sovereign Identity $-$ Opportunities and Challenges for the Digital Revolution (2017)

The interconnectedness of people, services and devices is a defining aspect of the digital revolution, and, secure digital identities are an important prerequisite for secure and legally compliant information exchange. Existing approaches to realize a secure identity management focus on central providers of identities such as national authorities or online service providers. Hence, changing residence or service provider often means to start over and creating new identities, because procedures for data portability are missing. Self-sovereign digital identities are instead created and managed by individuals, and enable them to maintain their digital identities independent from residence, national eID infrastructure and market-dominating service providers.
Network Traffic Classification techniques and comparative analysis using Machine Learning algorithms (2016)

Network Traffic Classification is a central topic nowadays in the field of computer science. It is a very essential task for Internet service providers (ISPs) to know which types of network applications flow in a network. Network Traffic Classification is the first step to analyze and identify different types of applications flowing in a network. Through this technique, internet service providers or network operators can manage the overall performance of a network. There are many methods traditional technique to classify internet traffic like Port Based, Pay Load Based and Machine Learning Based technique. The most common technique used these days is Machine Learning (ML) technique. Which is used by many researchers and got very effective accuracy results. In this paper, we discuss network traffic classification techniques step by step and real time internet data set is develop using network traffic capture tool, after that feature extraction tool is use to extract features from the capture traffic and then four machine learning classifiers Support Vector Machine, C4.5 decision tree, Naïve Bays and Bayes Net classifiers are applied. Experimental analysis shows that C4.5 classifiers gives very good accuracy result as compare to other classifies.
High-speed confocal fluorescence lifetime imaging microscopy (FLIM) with the analog mean delay (AMD) method (2011)

We demonstrate a high-speed confocal fluorescence lifetime imaging microscopy (FLIM) whose accuracy and photon economy are as good as that of a time-correlated single photon counting (TCSPC). It is based on a new lifetime determination scheme, the analog mean delay (AMD) method. Due to the technical advantages of multiple fluorescence photon detection capability, accurate lifetime determination scheme and high photon detection efficiency, the AMD method can be the most effective method for high-speed confocal FLIM. The feasibility of real-time confocal FLIM with the AMD method has been demonstrated by observing the dynamic reaction of calcium channels in a RBL-2H3 cell with respect to 4αPDD stimulus. We have achieved the photon detection rate of 125 times faster than a conventional TCSPC based system in this experiment.
Phage Resistance in a Phage-Insensitive Strain of <i>Streptococcus lactis</i> : Temperature-Dependent Phage Development and Host-Controlled Phage Replication (1984)

Streptococcus lactis ME2 is a dairy starter strain that is insensitive to a variety of phage, including phi18. The efficiency of plating of phi18 on ME2 and N1 could be increased from <1 x 10 to 5.0 x 10 and from 7.6 x 10 to 2.1 x 10, respectively, when the host strains were subcultured at 40 degrees C before plating the phage and the phage assay plates were incubated at 40 degrees C. Host-dependent replication was demonstrated in N1 at 30 degrees C and in N1 and ME2 at 40 degrees C, suggesting the operation of a temperature-sensitive restriction and modification system in ME2 and N1. The increased sensitivity of ME2 and N1 to phi18 at 40 degrees C was also demonstrated by lysis of broth cultures and increased plaque size. ME2 grown at 40 degrees C showed an increased ability to adsorb phi18, indicating a second target for temperature-dependent phage sensitivity in ME2. Challenge of N1 with a phi18 preparation that had been previously modified for growth on N1 indicated that at 40 degrees C phage development was characterized by a shorter latent period and larger burst size than at 30 degrees C. The evidence presented suggests that the high degree of phage insensitivity expressed by ME2 consists of a variety of temperature-sensitive mechanisms, including (i) the prevention of phage adsorption, (ii) host-controlled restriction of phage, and (iii) suppression of phage development. At 30 degrees C these factors appear to act cooperatively to prevent the successful emergence of lytic phage active against S. lactis ME2.
Entanglement generation and quantum information transfer between spatially-separated qubits in different cavities (2013)

The generation and control of quantum states of spatially-separated qubits distributed in different cavities constitute fundamental tasks in cavity quantum electrodynamics. An interesting question in this context is how to prepare entanglement and realize quantum information transfer between qubits located at different cavities, which are important in large-scale quantum information processing. In this paper, we consider a physical system consisting of two cavities and three qubits. Two of the qubits are placed in two different cavities while the remaining one acts as a coupler, which is used to connect the two cavities. We propose an approach for generating quantum entanglement and implementing quantum information transfer between the two spatially-separated intercavity qubits. The quantum operations involved in this proposal are performed by a virtual photon process, and thus the cavity decay is greatly suppressed during the operations. In addition, to complete the present tasks, only one coupler qubit and one operation step are needed. Moreover, there is no need of applying classical pulses, so that the engineering complexity is much reduced and the operation procedure is greatly simplified. Finally, our numerical results illustrate that high-fidelity implementation of this proposal using superconducting phase qubits and one-dimenstion transmision line resonators is feasible for current circuit QED implementations. This proposal can also be applied to other types of superconducting qubits, including flux and charge qubits.
Endothelial Dysfunction (2004)

Endothelial dysfunction is characterized by a shift of the actions of the endothelium toward reduced vasodilation, a proinflammatory state, and prothrombic properties. It is associated with most forms of cardiovascular disease, such as hypertension, coronary artery disease, chronic heart failure, peripheral artery disease, diabetes, and chronic renal failure. Mechanisms that participate in the reduced vasodilatory responses in endothelial dysfunction include reduced nitric oxide generation, oxidative excess, and reduced production of hyperpolarizing factor. Upregulation of adhesion molecules, generation of chemokines such as macrophage chemoattractant peptide-1, and production of plasminogen activator inhibitor-1 participate in the inflammatory response and contribute to a prothrombic state. Vasoactive peptides such as angiotensin II and endothelin-1; the accumulation of asymmetric dimethylarginine, an endogenous nitric oxide inhibitor; hypercholesterolemia; hyperhomocysteinemia; altered insulin signaling; and hyperglycemia can contribute to these different mechanisms. Detachment and apoptosis of endothelial cells (anoikis) are associated phenomena. Endothelial dysfunction is an important early event in the pathogenesis of atherosclerosis, contributing to plaque initiation and progression. Reductions in circulating endothelial progenitor cells that participate in regeneration of the endothelium participate in endothelial pathophysiology. The severity of endothelial dysfunction has been shown to have prognostic value for cardiovascular events. Correction of endothelial dysfunction may be associated with reduced cardiovascular risk. Circulating endothelial progenitor cells may represent a potential therapeutic approach for endothelial dysfunction.
Dynamic Formation of a Hot Field Reversed Configuration with Improved Confinement by Supersonic Merging of Two Colliding High-<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>β</mml:mi></mml:math>Compact Toroids (2010)

A hot stable field-reversed configuration (FRC) has been produced in the C-2 experiment by colliding and merging two high-$\ensuremath{\beta}$ plasmoids preformed by the dynamic version of field-reversed $\ensuremath{\theta}$-pinch technology. The merging process exhibits the highest poloidal flux amplification obtained in a magnetic confinement system (over tenfold increase). Most of the kinetic energy is converted into thermal energy with total temperature (${T}_{i}+{T}_{e}$) exceeding 0.5 keV. The final FRC state exhibits a record FRC lifetime with flux confinement approaching classical values. These findings should have significant implications for fusion research and the physics of magnetic reconnection.
