Numerical analysis of resonant and lasing properties at a defect region within a random structure (2009)

We propose a simple structure for manipulating resonant conditions in random structures, in which a "defect" region where no scatterer is set is deliberately made in the structure. By employing a two-dimensional finite-difference time-domain method including rate equations, we examine the resonant and lasing properties observed at the defect region by changing the filling factor of scatterers. From the numerical results, we confirm that an distinct localized spot at the defect can be realized by determining an optimal filling factor and scatterer size and selecting the appropriate defect size.
The Design of a Hierarchical Circuit-Level Simulator (1984)

We describe a 48-y-old male with chronic progressive myelopathy suggesting thoracic intramedullary neoplasm but in whom laboratory workup disclosed Schistosoma mansoni myelopathy. The case illustrates the need for careful investigation of schistosomiasis in patients from endemic regions with myeloradiculopathy signs.

A BAC-Based Physical Map of the Chicken Genome (2003)

A genome-wide physical map constructed with bacterial artificial chromosomes (BACs) is an essential component in linking phenotypic traits to the responsible genetic variation in the genomes of plants and animals. We have constructed a physical map of the chicken genome from 57,091 BACs (7.9-fold haploid genome coverage) by restriction fingerprint analysis using high-resolution polyacrylamide gel electrophoresis. The physical map consists of 2331 overlapping BAC contigs and is estimated to span 1510 Mb in physical length. BAC contigs were verified manually and by screening the BACs with 367 DNA markers. A total of 361 of the contigs have been anchored to the existing chicken genetic map. This map represents the first genome-wide, BAC-based physical map of the chicken genome. It provides a powerful platform for many areas of chicken genomics, including targeted marker development, fine mapping of genes and QTL alleles, positional cloning, analysis of avian genome organization and evolution, chicken-mammalian comparative genomics, and large-scale genome sequencing.
Mechanism of Action of Sucrose Phosphorylase (1972)

Abstract Sucrose phosphorylase is active in various alcohol-water mixtures and can catalyze the transfer of the glucosyl moiety of sucrose to the alcohols forming the corresponding glucosides. The efficiency of the glucosyl acceptor (Vmax/Km) decreases in the order: trans-1,2-cyclohexanediol (0.057) ≈ ethylene glycol (0.061) g methanol (0.017) ≈ cis-1,2-cyclohexanediol (0.015) g ethanol (0.002) g water (0.001). The dependence of the rates on the concentration of each of the alcohols yields kinetics which shows saturation suggesting that each of the alcohols binds to the enzyme. The apparent Vmax for most of the alcohols is similar to the hydrolytic rate. trans-1,2-Cyclohexanediol and ethylene glycol react with the glucosyl enzyme without reducing the rate of hydrolysis although the water concentration is significantly reduced as the concentration of the alcohol is varied (e.g. 0 to 30% ethylene glycol by volume). trans-1,2-Cyclohexanediol is competitive with phosphate and noncompetitive with sucrose. Ethylene glycol is noncompetitive with both phosphate and sucrose. cis-1,2-Cyclohexanediol and methanol reduce the rate of hydrolysis. The reaction with methanol yields α-methylglucoside, and its rate of formation is apparently not reduced by phosphate. It was concluded that two separate, independent binding sites exist. These were designated water site, at which water and probably methanol react, and acceptor site, at which phosphate and the sugar acceptors as well as trans-1,2-cyclohexanediol and ethylene glycol react. The site of interaction of cis-1,2-cyclohexanediol is uncertain. Two adjacent hydroxyl groups on the glucosyl acceptor molecule seems to be a necessary, but possibly not a sufficient property for interaction at the acceptor site.
A High-Speed FDCT Processor for Real-Time Processing of NTSC Color TV Signal (1982)

A FDCT (fast discrete cosine transform) processor is designed to have throughput rates consistent with high speed, (real time) processing of standard National Television Systems Committee (NTSC) color television signal sampled at 3fsc = 10.7 MHz where fsc is the color subcarrier frequency. This is achieved by using a highly modular structure in a pipeline configuration. The development phase includes the selection of a suitable algorithm and the utilization of important features of the algorithm for hardware implementation. Since the prototype is used for research purposes, provisions are made for versatility of the control and selectabilifty of , the processing accuracy. The FDCT processor is capable of processing 4- or 8- or 16- point input segments and can also be used as a part of a larger system which processes a 32-point input segment. With minor modifications, the algorithm and the basic hardware design can be used for the fast inverse DCT (FIDCT) processor.
Correlation of polymerase replication fidelity with genetic evolution of influenza A/Fujian/411/02(H3N2) viruses (2011)

Influenza virus evolves continuously through mutations presumed to result from evolutionary pressure driving viral replication. This study examined the relationship between the genetic evolution and replication fidelity of influenza viruses. Analysis of influenza sequences from National Centre for Biotechnology Information (NCBI) database revealed a gradual decrease in the rate of genetic evolution of A/Fujian/411/02(H3N2)-like variants after the emergence and predominance of the A/H3N2 Fujian strain in 2002. This decrease may be related to an increase in replication fidelity, which was investigated by assessing mutation frequencies of reassortant viruses carrying the PB1 segment of Fujian variants isolated between 2003 and 2005 in a sequencing-based plaque assay. The data revealed a threefold decrease in substitution per site of the reassortant viruses carrying the Fujian PB1 segments isolated in 2004-2005 compared with those circulating in 2003. The decrease in mutation frequency paralleled a decrease in genetic evolution of the Fujian variants from the NCBI database. This correlation implicates changes in the polymerase replication fidelity as contributing to altered genetic evolution of influenza viruses.
Graphical methodology language for CAD frameworks (2002)

The Ulysses II CAD framework executes a design methodology programmed in the graphical scripts language using data-entry forms and syntax-directed editing. Graphical programming eliminates the need to memorize language syntax and speeds methodology entry. The language has an intelligent error handling system that facilitates methodology debugging. The language encapsulates tools, manipulates CAD data, schedules tools, balances network loads, and maintains data consistency. Ulysses II was used to produce several designs including a 64-bit ALU.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The Evolution of E-Business Environment in Fashion Sector (2010)

Businesses have been changed considerable over the past years as the technology has played strategic role in gaining competitive advantage in the market. The new era of Internet enables major corporations to develop and establish stronger relations with customers and other businesses based on the quick movement of the information and the quick response to customers' requirements. The business environment is changing continuously and the technology has become the mean for managing the challenges of the recent days with the most efficient and accurate way. The capabilities of the Internet are numerous as via its well developed infrastructure the companies can link their internal and external data processing systems more efficiently and flexible by working closely with suppliers and partners, collaborating on sales promotions, doing joint research and better manage customers expectations. Going online, a company has to decide which of the E-Business models suits better to its goals. This paper will introduce the different E-Business models which exist according to the literature review and then it will identify which is the most preferable for fashion businesses. Then it will investigate customers' preferences in buying clothing and fashion products online and also how familiar are with internet purchases. As the meaning of E-Business is broad and multi-functional this pilot study will be focused more on e-commerce and will examine a number of fashion retailers according to their Business to Customer (B2C) model and their communication and interaction with their customers. An assessment of how risky this model can be for both sides will give a clear idea of how safe e-purchases can be for customers and how the companies can gain competitive advantage in the market over their competitors.
Integration of Privacy Protection Mechanisms in Location-Based Services (2013)

In the next few years, we will see the upcoming of location-based services. Such LBSs will be extremely heterogeneous. Protecting the privacy of the users in such a situation requires flexible approaches. A single privacy protection mechanism is often insufficient. The contribution of this paper is two-fold. First we present LbSprint, a middleware architecture for location-based services which integrates different privacy mechanisms by means of the standard XACML language. The system administrator can configure and extend the set of such mechanisms. To the best of our knowledge, this is the first proposal of an architecture which integrates many privacy mechanisms in an extensible way. Secondly, we present practical optimizations which considerably improves the performance of the XACML policy evaluation process.
Genetic Transformation of Populus trichocarpa Genotype Nisqually-1: A Functional Genomic Tool for Woody Plants (2006)

We report here the Agrobacterium-mediated genetic transformation of Nisqually-1, a Populus trichocarpa genotype whose genome was recently sequenced. Several systems were established. Internodal stem segments from vigorously growing greenhouse plants are the explants most amenable to transformation. For the most efficient system, approximately 40% of the stem segments infected with pBI121-containing Agrobacterium tumefaciens C58 produced transgenic calli, as confirmed by beta-glucuronidase (GUS) staining. The regeneration efficiency of independent transgenic plants was approximately 13%, as revealed by genomic Southern analysis. Some transgenic plants were produced in as little as 5 months after co-cultivation. This system may help to facilitate studies of gene functions in tree growth and development at a genome level.
Sandwich repair with two sheets of equine pericardial patch for acute posterior post-infarction ventricular septal defect (1993)

A 74-year-old man, who had posterior post-infarction ventricular septal defect, was treated successfully by early surgical repair with a sandwich technique involving two sheets of equine pericardial patch. In this technique the ventricular septal defect (VSD) was exposed through a trans-infarction approach. The inside patch covered the VSD and ventriculotomy from the inside. The outside patch generously covered the infarcted myocardium. The two patches completely sandwiched the infarcted myocardium including the VSD and ventriculotomy with eighteen interrupted sutures. This technique ensures strong fixation of the VSD, reducing the risk of bleeding and recurrence of VSD, and also maintains the proper shape and size of the left ventricle without the danger of ventricular aneurysm formation.
Application of Coacervated α-Elastin to Arterial Prostheses for Inhibition of Anastomotic Intimal Hyperplasia (1998)

Prevention of anastomotic intimal hyperplasia (AIH) requires inhibition of the migration of smooth muscle cells (SMCs) and promotion of endothelial cell (ECs) growth from the native arterial wall. We investigated the effect of coacervated alpha-elastin on migration of SMCs and ECs in vitro. SMCs and ECs were prepared from porcine aortic media and endothelium. Coacervated alpha-elastin was coated and cross-linked around the perimeter of each 1 cm diameter center of a well in a 12 well plate. SMCs and ECs were placed and cultured within the center of each well. The migration of SMCs and ECs on coacervated alpha-elastin was assayed on the second, third (10 mg/ml), or fourth day (0.1, 1.0, 10.0 mg/ml) of cultivation by measuring the area of migration from the 1 cm diameter center. Coacervated alpha-elastin was then coated and cross-linked on a Dacron graft using 1% glycerol polyglycidyl ether (GPGE) and examined with scanning electron microscopy to determine the feasibility of graft coating. SMC migration was significantly inhibited dose dependently over time (p < 0.005), e.g., 0.1 mg/ml (45.4% +/- 2.7%: % of MES [pH 5] and 1% GPGE without alpha-elastin), 1.0 mg/ml (32.0% +/- 1.4%), 10.0 mg/ml (8.3% +/- 2.9%). EC migration (90.7% +/- 6.2%: p = ns) was not inhibited by 0.1 mg/ml of coacervated alpha-elastin. Cross-linked coacervated alpha-elastin was coated on a dacron graft uniformly. Incorporation of coacervated alpha-elastin into the structure of arterial prostheses offers the possibility of inhibition of SMC hyperplasia without inhibition of EC formation.
Androgen Regulation of Programmed Death of Normal and Malignant Prostatic Cells (1992)

Androgen-dependent normal prostatic glandular cells and androgen-dependent prostatic cancer cells can be induced to undergo cell death after androgen ablation. This death does not require the cells to proliferate and occurs as an energy-dependent process collectively referred to as "programmed cell death" in which the cells actively commit "suicide." Associated with this programmed cell death pathway is the enhanced expression of a series of genes and the fragmentation of the genomic DNA into nucleosomal oligomers. This genomic DNA fragmentation is the irreversible commitment step in the death of the cell and results from activation of Ca2+/Mg(2+)-dependent endonuclease activity within the cell nucleus. This activation is due to sustained elevation of intracellular free Ca2+ (Cai) induced after androgen ablation. Metastatic prostatic cancer within an individual patient is heterogeneous, including both androgen-dependent and -independent cancer cells. Thus, androgen ablation is rarely curative since it only induces the programmed death of the androgen-dependent cancer cells without activating this pathway in the androgen-independent cancer cells within the patient. Androgen-independent prostatic cancer cells do not activate this death process after androgen ablation, since this does not induce a sustained increase in Cai. A new approach to treat androgen-independent prostatic cancer cells has focused on the use of chemotherapeutic agents to induce a sustained increase in Cai. These studies demonstrate that if such a sustained elevation in Cai is maintained, even androgen-independent prostatic cancer cells undergo programmed cell death.
Allocation Fairness for MIMO Precoded UTRA-LTE TDD System (2008)

In future time division duplex (TDD)-based broadband wireless systems, it will be possible to exploit the channel reciprocity to implement channel state information (CSI)-based multi user multiple input multiple output (MU-MIMO) techniques, which will ensure highly efficient spectrum usage. To increase the cell coverage while ensuring the quality of service (QoS) for all UEs across the cell area, fairness should be maximized as much as possible. This paper presents a novel way to help improving fairness performance in the physical layer, via fair power allocation together with resource allocation, in MU-MIMO precoding scenarios where the common approach of guaranteeing fairness at MAC layer is not feasible. The results presented in this paper show that the proposed algorithm is able to reduce the system outage event to a large extent, thus increases fairness.
Studies on the Components in NTU Shale Oil. IV. : The Hofmann Degradation of Open-Chain Quaternary Ammonium Compounds (1971)

Thermal decomposition of sec-alkyldimethylamine methohydroxide (VIII, XII) was examined by pyrolysis-gas chromatographic method, with respect to two reactions, β-elimination and substitution at N-methyl groups. Its result, when compared with known results for methohydroxides of alkyldimethylamines, illustrated the marked inhibitory effect of an alkyl group attached to the α-carbon atom on β-elimination, relative to substitution. Branching of a sec-alkyl group at the γ-carbon atom farther decreases the conversion of to an olefin. The relative ammount of isomeric olefins formed in the thermal decomposition of unsymmetrical sec-alkyl quaternary ammonium compounds was also determined.
EAST, an Epidermal Growth Factor Receptor- and Eps15-associated Protein with Src Homology 3 and Tyrosine-based Activation Motif Domains (1998)

We describe the cloning and characterization of a new cytoplasmic protein designated epidermal growth factor receptor-associated protein with SH3- and TAM domains (EAST). It contains an Src homology 3 domain in its midregion and a tyrosine-based activation motif in its COOH terminus. Antibodies to EAST recognize a 68-kDa protein that is present in most chicken tissues. An epidermal growth factor (EGF)-dependent association between the EGF receptor (EGFR) and EAST was shown by reciprocal immunoprecipitation/immunoblotting studies with specific antibodies. Activated EGFR catalyzed the tyrosine phosphorylation of EAST, as judged by an in vitro kinase assay with both immunoprecipitated and purified EGFR. Immunoprecipitation/immunoblotting experiments also demonstrated an association between EAST and eps15, an EGFR substrate associated with clathrin-coated pits and vesicles, which is essential in the endocytotic pathway. The association between EAST and eps15 was not affected by EGF treatment. In immunofluorescence microscopy, EAST was shown to partially colocalize with clathrin. The sequence of the NH2-terminal portion of EAST shows a high degree of similarity with a group of proteins involved in endocytosis or vesicle trafficking. Thus, EAST is a novel signal transduction component probably involved in EGF signaling and in the endocytotic machinery.
Quantum computers can search rapidly by using almost any selective transformation (2008)

The search problem is to find a state satisfying certain properties out of a given set. Grover's algorithm drives a quantum computer from a prepared initial state to the target state and solves the problem quadratically faster than a classical computer. The algorithm uses selective transformations to distinguish the initial state and target state from other states. It does not succeed unless the selective transformations are very close to phase inversions. Here we show a way to go beyond this limitation. An important application lies in quantum error correction, where the errors can cause the selective transformations to deviate from phase inversions. The algorithms presented here are robust to errors as long as the errors are reproducible and reversible. This particular class of systematic errors arises often from imperfections in the apparatus setup. Hence our algorithms offer a significant flexibility in the physical implementation of quantum search.
