Real–Time Estimation of User–Level QoS of Audio–Video Transmission over IP Networks (2006)

This paper proposes a real-time estimation method of perceptual QoS (i.e., user-level QoS) of audio-video transmission over IP networks. The estimated quality reflects cross-modal influences of audio and video in the framework of ITU-T Recommendation J. 148. As objective measures of audio and video for the use of the perceptual QoS estimation, we select application-level QoS parameters for media synchronization quality. The perceptual quality is expressed in terms of the user-level QoS parameter of the interval scale, which is referred to as the psychological scale. As the multimedia quality integration function, we propose QoS parameter mapping between the application-level and the user-level. We made subjective quality assessment of simulated audio-video transmission over an IP network by the rating-scale method. We then calculate the psychological scale, utilizing the law of categorical judgment. Furthermore, we obtain the QoS mapping relations by the principal component analysis and multiple regression analysis. The regression formula thus derived can estimate the psychological scale with high accuracy unless the video frame rate is low. Finally we present an extension of the proposed method to continuous time estimation of user-level QoS.
Temporal and spatial isolation in a virtualization layer for multi-core processor based information appliances (2011)

A virtualization layer makes it possible to compose multiple functionalities on a multi-core processor with minimum modifications of OS kernels and applications. A multi-core processor is a good candidate to compose various software independently developed for dedicated processors into one multi-core processor to reduce both the hardware and development cost. In this paper, we present SPUMONE, which is a virtualization layer suitable for developing multi-core processor based-information appliances.
EFFICIENCY EVALUATION OF NAY ZEOLITE AND TIO2/NAY ZEOLITE IN REMOVAL OF METHYLENE BLUE DYE FROM AQUEOUS SOLUTIONS (2011)

In this study titanium dioxide cluster was incorporated onto NaY zeolite and characterized with X-Ray diffractometer and X-ray spectroscopy. These composites have many advantages such as high stability and high porosity. The adsorption behavior of methylene blue was investigated for NaY zeolite and TiO2/NaY zeolite. The efficiency of time, pH, temperature and initial concentration of methylene blue (MB) on removal effect of methylene blue was investigated by UV-Vis spectroscopy. And, the optimum conditions were determined 8h time, basic pH and high initial concentrations of methylene blue and absorbent. With increasing of temperature, the removal efficiency of NaY zeolite and TiO2/NaY increased. Results showed that 92% and 85% of methylene blue was absorbed by synthesized NaY zeolite and TiO2/zeolite, respectively. Adsorption isotherm as studied by fitting data to Langmuir and Freundlich isotherms models, showed monolayer adsorption and Langmuir equilibrium model to be more relevant.
Sulfated quaternary amine lipids: a new class of inverse charge zwitterlipids (2014)

We describe a new class of charge inverted zwitterionic sulfated lipids (AS) with a cationic quaternary amine anchored at the membrane interface and an anionic sulfate moiety extended into the aqueous phase. These lipids have exceptionally high transition temperatures and assemble into lipid aggregates when dispersed in aqueous solutions.
Efficient Parallel Graph Exploration on Multi-Core CPU and GPU (2011)

Graphs are a fundamental data representation that has been used extensively in various domains. In graph-based applications, a systematic exploration of the graph such as a breadth-first search (BFS) often serves as a key component in the processing of their massive data sets. In this paper, we present a new method for implementing the parallel BFS algorithm on multi-core CPUs which exploits a fundamental property of randomly shaped real-world graph instances. By utilizing memory bandwidth more efficiently, our method shows improved performance over the current state-of-the-art implementation and increases its advantage as the size of the graph increases. We then propose a hybrid method which, for each level of the BFS algorithm, dynamically chooses the best implementation from: a sequential execution, two different methods of multicore execution, and a GPU execution. Such a hybrid approach provides the best performance for each graph size while avoiding poor worst-case performance on high-diameter graphs. Finally, we study the effects of the underlying architecture on BFS performance by comparing multiple CPU and GPU systems, a high-end GPU system performed as well as a quad-socket high-end CPU system.
Interactive simulation and rendering of heterogeneous deformable bodies (2005)

In this paper, we present an interactive method for physics-based simulation and rendering of deformable bodies exhibiting heterogeneous material properties. To fully exploit the capabilities of consumer class computer systems, a CPU simulation engine is run in parallel with a GPU render engine. On the simulation side, we have developed a numerical multigrid solver for the governing equations of motion of deformable bodies. This solver allows for the combination of implicit solution methods and varying material parameters into an unconditionally stable simulation support system. The deformable model is rendered using a high-resolution surface mesh, which is subsequently updated on the GPU to exploit parallelism and memory bandwidth. Rendering of the deformed mesh can thus be performed without any additional bus-transfer. The interactive system is open to a variety of different applications ranging from surgery simulation, medical imaging and solid mechanics to computer animation and virtual sculpting.
Using pattern homogenization of binary grayscale masks to fabricate microfluidic structures with 3D topography (2007)

Because fluids at the microscale form three dimensional interfaces and are subject to three dimensional forces, the ability to create microstructures with modulated topography over large areas could greatly improve control over microfluidic phenomena (e.g., capillarity and mass transport) and enable exciting novel microfluidic applications. Here, we report a method for the fabrication of three-dimensional relief microstructures, based on the emergence of smooth features when a photopolymer is exposed to UV light through a transparency mask with binary motifs. We show that homogeneous features emerge under certain critical conditions that are also common to other, apparently unrelated, phenomena such as the emergence of macroscopic continuum properties of composite materials and the rates of ligand binding to cell membrane receptors. This fabrication method is simple and inexpensive, and yet it allows for the fabrication of microstructures over large areas (centimetres) with topographic modulation of features with characteristic dimensions smaller than 100 micrometres.
The EROP-Moscow oligopeptide database (2005)

Natural oligopeptides may regulate nearly all vital processes. To date, the chemical structures of nearly 6000 oligopeptides have been identified from >1000 organisms representing all the biological kingdoms. We have compiled the known physical, chemical and biological properties of these oligopeptides--whether synthesized on ribosomes or by non-ribosomal enzymes--and have constructed an internet-accessible database, EROP-Moscow (Endogenous Regulatory OligoPeptides), which resides at http://erop.inbi.ras.ru. This database enables users to perform rapid searches via many key features of the oligopeptides, and to carry out statistical analysis of all the available information. The database lists only those oligopeptides whose chemical structures have been completely determined (directly or by translation from nucleotide sequences). It provides extensive links with the Swiss-Prot-TrEMBL peptide-protein database, as well as with the PubMed biomedical bibliographic database. EROP-Moscow also contains data on many oligopeptides that are absent from other convenient databases, and is designed for extended use in classifying new natural oligopeptides and for production of novel peptide pharmaceuticals.
Annotated Bibliography Of Resources For Researching Danish-American Folklife (1996)

Danish-American folklife consists of the expressions of traditional culture that identify Americans of Danish heritage as belonging to this small ethnic group. Encompassing a full range of expressive behavior, ranging from building and decorating immigrant homes to crafting intricate patterns with knitting needles, scissors, hammer and anvil, Danish-American folklife includes any form of knowledge or skill that is learned by observation or imitation within a community context (Hansen 1988:23)
Glow discharge in microfluidic chips for visible analog computing (2002)

Here we present a novel visible analog computing approach for solving a wide class of shortest path problems. Using a microfluidic chip for computation, based on the lighting up of a glow discharge, the solution to maze search problems, the solution of a network shortest path and k-shortest paths problems and the practical application of finding the shortest paths between several landmarks from a street map are presented. The solution and visible display (in real time) for these problems shows only a small difference in practical problem solving time among problems with varying differences in size.
Rat brain preproenkephalin mRNA. cDNA cloning, primary structure, and distribution in the central nervous system. (1984)

A cDNA-clone library was constructed from poly-adenylated RNA of Fischer rat striatum and screened for inserts coding for the enkephalin precursor preproenkephalin. The insert of one positive clone, pRPE2, was sequenced and found to contain the coding sequence (810 bases), as well as 316 and 155 bases of the 3' and 5' untranslated regions, respectively, of rat preproenkephalin mRNA. The primary structure of rat preproenkephalin (269 amino acids, Mr 30,932) is similar to those of previously sequenced bovine and human preproenkephalins (78 and 82% matched residues, respectively), and contains four copies of Met-enkephalin, one of Leu-enkephalin, one of Met-enkephalin-Arg6-Gly7-Leu8, and one of Met-enkephalin-Arg6-Phe7. Cell-free translation of rat striatal mRNA selected by hybridization with pRPE2 DNA resulted in the synthesis of a 31,000-Da protein. Southern analysis of rat genomic DNA with 32P-labeled pRPE2 fragments is consistent with a single preproenkephalin gene. A 32P-labeled pRPE2 fragment hybridized specifically with preproenkephalin mRNA (approximately 1500 bases) on Northern blots of polyadenylated or total RNA of all brain regions but not liver. Relative abundances of preproenkephalin mRNA in total RNA of specific regions of the rat central nervous system, determined by a sensitive dot-blot hybridization assay, had the following order: striatum much greater than hypothalamus, pons-medulla, spinal cord greater than cerebellum, midbrain, frontal cortex greater than hippocampus, thalamus. The pRPE2 probe is useful for the analysis of the dynamics of preproenkephalin mRNA in rat neurons.
The Use of Chang Cells Cultured <i>in Vitro</i> to Evaluate Potential Iron Chelating Drugs (1976)

A number of iron chelating agents, consisting largely of hydroxamic acid and benzoic acid derivatives, have been studied in an in vitro Chang cell culture system to determine their effect on cellular iron uptake, ferritin synthesis and the incorporation of iron into ferritin. The results have been compared with those of a previous study in which iron balance was determined in hypertransfused rats. Both techniques appear to be of value in screening new iron chelating agents for potential therapeutic use in patients with iron overload.
Stretchable Thin‐Film Electrodes for Flexible Electronics with High Deformability and Stretchability (2015)

Flexible and stretchable electronics represent today's cutting-edge electronic technologies. As the most-fundamental component of electronics, the thin-film electrode remains the research frontier due to its key role in the successful development of flexible and stretchable electronic devices. Stretchability, however, is generally more challenging to achieve than flexibility. Stretchable electronic devices demand, above all else, that the thin-film electrodes have the capacity to absorb a large level of strain (>>1%) without obvious changes in their electrical performance. This article reviews the progress in strategies for obtaining highly stretchable thin-film electrodes. Applications of stretchable thin-film electrodes fabricated via these strategies are described. Some perspectives and challenges in this field are also put forward.
Refurbishment of turbine generators (1988)

There are two possible strategies which can be applied to the refurbishment of turbine generators: the unit is operated until there is a breakdown or a serious fault is discovered during maintenance, the repair/corrective modification is then applied to all similar units during subsequent planned outages; or, the generator is completely refurbished for a specified extended design life with accompanying technical and commercial assurances. Recently, generating utilities have embarked on the second strategy and the main part of the authors' work concentrates on the scope of work necessary for complete refurbishment. An outline is given of the inspection and analytical methods used in the revalidation of the stator fabrications and rotor forging. The replacement of materials with modern alternatives is discussed and design changes to improve the reliability and flexibility of the unit are also considered. >
An Evaluation of Hemoglobin Determination Using Sodium Lauryl Sulfate (1993)

The standard reference method for hemoglobin determination for years has been the photometric quantitation of cyanmethemoglobin. Other existing methods have not gained popularity in North America. In an attempt to eliminate hazardous cyanide waste, a method to determine the hemoglobin concentration in whole blood using sodium lauryl sulfate has been devised and recently was released as a commercial reagent. The authors compare this new method with the cyanmethemoglobin method using two hematology analyzers. Their results show that there is excellent correlation between the two methods (r2 = 0.996). In addition, other elements of the complete blood count also show good correlation. Thus, it was confirmed that the sodium lauryl sulfate method of estimating hemoglobin concentration is an appropriate alternative to the cyanmethemoglobin method and avoids the generation of toxic wastes.

Life cycle assessment is used to determine impact reductions for greenhouse gas emission and fossil resource depletion for production of polyethercarbonate polyols using CO<sub>2</sub> from flue gases as feedstock.
Automatic Updates of Interactive Information Visualization User Interfaces Supporting Multimedia Information Retrieval through Database Triggers (1999)

this paper, however, we describe an approach to the problem of updating visualization clients based on the usage of a set of active rules. Architectural issues on all these approaches for database-driven information visualization have been discussed to some extent in [LHN99]. Our solution is realized through the use of database triggers which, today, are often implemented in existing database management systems (DBMS) [WC96a]. Database triggers are a mechanism used to define a set of operations which are to be executed by the DBMS as soon as a given part of the data in the database changes.
Plane-wave theory of time-domain fields : near-field scanning applications (1999)

"This invaluable book provides a comprehensive framework for the formulation and solution ofnumerous problems involving the radiation, reception, propagation, and scattering of electromagnetic and acoustic waves. Filled with original derivations and theorems, it includes the first rigorous development of plane-wave expansions for time-domain electromagnetic and acoustic fields. For the past 35 years, near-field measurement techniques have been confined to the frequency domain. Now, with the publication of this book, probe-corrected near-field measurement techniques have been extended to ultra-wide-band, short-pulse transmitting and receiving antennas and transducers. By combining unencumbered straightforward derivations with in-depth expositions of prerequisite material, the authors have created an invaluable resource for research scientists and engineers in electromagnetics and acoustics, and a definitive reference on plane-wave expansions and near-field measurements. Featured topics include: * An introduction to the basic electromagnetic and acoustic field equations * A rigorous development of time-domain and frequency-domain plane-wave representations * The formulation of time-domain, frequency-domain, and static planar near-field measurement techniques with and without probe-correction * Sampling theorems and computation schemes for time-domain and frequency-domain fields * Analytic-signal formulas that simplify the formulation and analysis of transient fields * Wave phenomena, such as ''electromagnetic missiles" encountered only in the time domain * Definitive force and power relations for electromagnetic and acoustic fields and sources."

Brine-Driven Eddies under Sea Ice Leads and Their Impact on the Arctic Ocean Mixed Layer (2008)

Abstract Eddy generation induced by a line-shaped salt flux under a sea ice lead and associated salt transport are investigated using a three-dimensional numerical model. The model is designed to represent a typical condition for the wintertime Arctic Ocean mixed layer, where new ice formation within leads is known to be one of the primary sources of dense water. The result shows that along-lead baroclinic jets generate anticyclonic eddies at the base of the mixed layer, and almost all the lead-originated salt is contained inside these eddies. These eddies survive for over a month after closing of the lead and transport the lead-originated salt laterally. Consequently, the lead-origin salt settles only on the top of the halocline and is not used for increasing salinity of the mixed layer. Sensitivity experiments suggest that the horizontal scale of generated eddies depends only on the surface forcing and is proportional to the cube root of the total amount of salt input. This scaling of eddy size is consistent with a theoretical argument based on a linear instability theory. Parameterizing these processes would improve representation of the Arctic Ocean mixed layer in ocean general circulation models.
Next-Generation Shipboard DC Power System: Introduction Smart Grid and dc Microgrid Technologies into Maritime Electrical Netowrks (2016)

In recent years, evidence has suggested that the global energy system is on the verge of a drastic revolution. The evolutionary development in power electronic technologies, the emergence of high-performance energy storage devices, and the ever-increasing penetration of renewable energy sources (RESs) are commonly recognized as the major driving forces of the revolution. The explosion in consumer electronics is also powering this change. In this context, dc power distribution technologies have made a comeback and keep gaining a commendable increase in research interest and industrial applications. In addition, the concept of flexible and smart distribution has also been proposed, which tends to exploit distributed generation and pack together the distributed RESs and local electrical loads as an independent and self-sustainable entity, namely a microgrid. At present, research in the area of dc microgrids has investigated and developed a series of advanced methods in control, management, and objective-oriented optimization that would establish the technical interface enabling future applications in multiple industrial areas, such as smart buildings, electric vehicles, aerospace/aircraft power systems, and maritime power systems.
Vaginal infection and preterm labour (1991)

There are two distinct bacteriological groupings commonly found in women in PTL, especially in PTL less than 34 weeks gestation. These bacteriological groups are women with bacterial vaginosis in pregnancy and women who demonstrate enteropharyngeal bacteria in the vagina.
Circularly Polarized, Aperture-coupled Patch Antennas for a 2.4 GHz RFID System (1999)

Antennas are key components of microwave RF identification (RFID) tagging systems because miniaturization of the transponder or tag is limited mainly by the antenna dimensions. Printed antennas are widespread in RFID systems due to their minimal processing costs. Compared to a classical patch antenna, aperture-coupled patch antennas offer an improvement in terms of the optimization of radiation characteristics and antenna size. The RFID system is operated in the 2.4 GHz industrial, scientific and medical (ISM) band. Due to the requirements of the modulation scheme, the aperture-coupled patch antennas are circularly polarized with switchable polarization sense.
Identification of a protein encoded by the trans activator gene tatIII of human T-cell lymphotropic retrovirus type III (1986)

The human T-cell lymphotropic virus type III (HTLV-III/LAV) is a retrovirus associated with acquired immune deficiency syndrome. The region on the viral genome that is necessary for trans-activation of the HTLV-III/LAV long terminal repeat called tatIII has previously been determined to lie between nucleotides 5365 and 5607. Here we report that a bacterial fusion protein containing amino acid sequences specified by the first coding exon of the tatIII gene is recognized by some patient antisera. We also demonstrate that lymphoid and epithelial cells that express the trans activator function express a 14-kilodalton (kDa) protein recognized by a patient antiserum that reacts with the bacterial tatIII fusion protein. Cells transiently transfected with a deletion mutant of the trans activator protein produce a 12-kDa protein rather than the 14-kDa protein. These observations indicate that the tatIII region contains a functional gene and is capable of expressing a protein that migrates with an apparent molecular size of 14 kDa in some lymphoid and epithelial cells transfected with plasmids containing the tatIII region. We propose that the product of the trans activator gene be designated p14tat-III.
Identification of Outliers in Multivariate Data (1996)

Abstract New insights are given into why the problem of detecting multivariate outliers can be difficult and why the difficulty increases with the dimension of the data. Significant improvements in methods for detecting outliers are described, and extensive simulation experiments demonstrate that a hybrid method extends the practical boundaries of outlier detection capabilities. Based on simulation results and examples from the literature, the question of what levels of contamination can be detected by this algorithm as a function of dimension, computation time, sample size, contamination fraction, and distance of the contamination from the main body of data is investigated. Software to implement the methods is available from the authors and STATLIB.
