A mobile tomographic gamma camera system for acute studies (1997)

A mobile tomographic gamma camera system, called Cardiotom Mark 1, has been developed for imaging the myocardium and other small organs. The Cardiotom system is based on a tomographic technique, ectomography, which is a limited view angle method using a rotating slant hole collimator (RSHC) and a stationary detector to produce projection images. This enables the ectomographic system to be implemented as a mobile system. With the system developed, almost 200 perfusion studies have been performed. The system is based on a second-hand detector and a 30/spl deg/ RSHC. By segmenting the collimator, total system efficiency is increased and acquisition time can be reduced by a factor equal to the number of segments. The system developed is PC-based and totally self-contained with data acquisition, reconstruction, and image presentation. The mobility of the system and the fact that the examination requires no patient cooperation enable acute studies of myocardial perfusion in the critically ill patient, either in the intensive care unit or the emergency room. A mobile system with three-dimensional imaging can offer new possibilities in cardiological research and diagnosis.
Patents on the Internet versus Patents Online:  A Snapshot in Time (1999)

Internet-based patent information resources have grown considerably in the past few years. Some of them offer search and display capabilities not available through commercial online patent databases, whereas the indexed online databases and the hosts that mount them offer in-depth searching, particularly in chemical areas, and other capabilities still not available on Internet-based databases. This article gives a state-of-the-art summary of Internet and online resources currently available and looks at capabilities unique to both.
Recent progress in understanding protein and lipid factors affecting hepatic VLDL assembly and secretion (2010)

Excess lipid induced metabolic disorders are one of the major existing challenges for the society. Among many different causes of lipid disorders, overproduction and compromised catabolism of triacylglycerol-rich very low density lipoproteins (VLDL) have become increasingly prevalent leading to hyperlipidemia worldwide. This review provides the latest understanding in different aspects of VLDL assembly process, including structure-function relationships within apoB, mutations in APOB causing hypobetalipoproteinemia, significance of modulating microsomal triglyceride-transfer protein activity in VLDL assembly, alterations of VLDL assembly by different fatty acid species, and hepatic proteins involved in vesicular trafficking, and cytosolic lipid droplet metabolism that contribute to VLDL assembly. The role of lipoprotein receptors and exchangeable apolipoproteins that promote or diminish VLDL assembly and secretion is discussed. New understanding on dysregulated insulin signaling as a consequence of excessive triacylglycerol-rich VLDL in the plasma is also presented. It is hoped that a comprehensive view of protein and lipid factors that contribute to molecular and cellular events associated with VLDL assembly and secretion will assist in the identification of pharmaceutical targets to reduce disease complications related to hyperlipidemia.
Induction and recall of immune memory by mucosal immunization with a non‐toxic recombinant enterotoxin‐based chimeric protein (2005)

Previous reports have suggested that peroral delivery of antigens chemically coupled to non-toxic recombinant enterotoxin B subunits, such as the cholera toxin B subunit (CTB), induces tolerance to the antigen that may be abrogated by the toxic enzyme activity of intact enterotoxins, such as cholera toxin (CT). The aim of this study was to examine the immunogenicity of a genetically coupled protein composed of the saliva-binding region (SBR) of the Streptococcus mutans surface antigen AgI/II and the non-toxic A2 and B subunits of CT (SBR-CTA2/B) compared with that of recombinant SBR admixed with CT (SBR + CT) and SBR chemically coupled to recombinant CTB (SBR-CTB) following peroral delivery by intragastric (i.g.) immunization. The results showed that i.g. immunization with SBR-CTA2/B, like SBR + CT, induced antigen-specific serum immunoglobulin G (IgG) and salivary IgA antibodies, and sensitized splenic T cells. Comparison studies with SBR-CTB produced serum IgG but not salivary IgA titres and failed to sensitize splenic cells. Immunization with SBR-CTA2/B via the intranasal route also primed for the recall of antigen-specific memory antibody responses 6 months later. These findings show that SBR-CTA2/B is an immunogenic, not tolerogenic, chimeric protein that can induce and recall antigen-specific memory responses upon mucosal immunization.
The use of inverse layout trees for hierarchical design rule checking (1989)

The inverse layout tree concept is used to perform fully hierarchical DRC without any constraints on the use of overlapping or incomplete cells that are completed at higher levels of hierarchy. Hierarchy is preserved and design rule violations are displayed in the cell where they should be corrected. The DRC is corner-based and processes 200-800 corners/second on a VAX 11/750.
A Nonsense Mutation in TMEM95 Encoding a Nondescript Transmembrane Protein Causes Idiopathic Male Subfertility in Cattle (2014)

Genetic variants underlying reduced male reproductive performance have been identified in humans and model organisms, most of them compromising semen quality. Occasionally, male fertility is severely compromised although semen analysis remains without any apparent pathological findings (i.e., idiopathic subfertility). Artificial insemination (AI) in most cattle populations requires close examination of all ejaculates before insemination. Although anomalous ejaculates are rejected, insemination success varies considerably among AI bulls. In an attempt to identify genetic causes of such variation, we undertook a genome-wide association study (GWAS). Imputed genotypes of 652,856 SNPs were available for 7962 AI bulls of the Fleckvieh (FV) population. Male reproductive ability (MRA) was assessed based on 15.3 million artificial inseminations. The GWAS uncovered a strong association signal on bovine chromosome 19 (P = 4.08 × 10(-59)). Subsequent autozygosity mapping revealed a common 1386 kb segment of extended homozygosity in 40 bulls with exceptionally poor reproductive performance. Only 1.7% of 35,671 inseminations with semen samples of those bulls were successful. None of the bulls with normal reproductive performance was homozygous, indicating recessive inheritance. Exploiting whole-genome re-sequencing data of 43 animals revealed a candidate causal nonsense mutation (rs378652941, c.483C>A, p.Cys161X) in the transmembrane protein 95 encoding gene TMEM95 which was subsequently validated in 1990 AI bulls. Immunohistochemical investigations evidenced that TMEM95 is located at the surface of spermatozoa of fertile animals whereas it is absent in spermatozoa of subfertile animals. These findings imply that integrity of TMEM95 is required for an undisturbed fertilisation. Our results demonstrate that deficiency of TMEM95 severely compromises male reproductive performance in cattle and reveal for the first time a phenotypic effect associated with genomic variation in TMEM95.
General Concepts and History of Living Radical Polymerization (2002)

Nanostructured tellurium semiconductor: from nanoparticles to nanorods (2012)

Selective fabrication of single crystalline tellurium nanorods of various lengths and spherical nanoparticles can be easily achieved by a simple hydrothermal reduction method. The product was characterised by X-ray diffraction, transmission electron microscopy, high-resolution transmission electron microscopy, selected area electron diffraction and energy-dispersive X-ray spectroscopy techniques. It was found that when the concentration of orthotelluric acid gradually increased from 4 to 10, 20, 30 and 50 mM with other conditions controlled, the morphology of the tellurium nanocrystals gradually changed from long nanorod to shorter nanorods and eventually became spherical. Based on the experimental results, the morphology control mechanism of tellurium nanocrytals was well reasoned.
Subband coding with vector quantization (2005)

Vector quantization (VQ) has previously [1] been examined as a technique to enhance performance in subband coding of speech at 9.6 kbit/s. The model in [1] serves as the basis for the new model presented here. Investigations of the statistics of the subband gains and normalized subband signals, and VQ of these, are presented. The investigations revealed some new aspects of using VQ in subband coding. Based on these observations a new model was developed and simulated. Compared to a scalar quantization (SQ) model, our VQ model proved to offer a gain of 2 dB in segmental signal-to-noise ratio (SNRseg) and a distinct improvement in perceptual speech quality.
Holographic imaging of macromolecules (1998)

The low energy electron point source microscope (kendroscope) is used to acquire in-line holograms of rodlike macromolecules of phthalocyaninato polysiloxane (PcPS). The molecules were placed on a new class of substrates, thin microstructured silicon membranes that have slits about 100 nm wide which can be “bridged” by the molecular chains. The resulting in-line holograms of PcPS were recorded digitally and reconstructed numerically via a Kirchoff–Helmholtz transform. The mechanisms of image formation and uncertainties relating to the interpretation of the holograms are discussed.

A simple and practical protocol for the palladium‐catalyzed cross‐coupling of boronic acids with methyl iodide (2004)

Abstract A combination of palladium acetate and tri‐1‐naphthylphosphine was found to be a highly efficient catalyst system for the cross‐coupling of arylboronic acids with methyl iodide at room temperature. The new process allows for a convenient introduction of methyl groups into various functionalized arenes under mild conditions. Copyright © 2004 John Wiley & Sons, Ltd.

종설 : 선진국의 약가정책 고찰을 통한 건강보험 약가제도의 개선방안 (2003)

General drug prices involve three stages: shipment stage, wholesaler stage and retad stage. Policies on drug price differ from country to country. Shipment stage prices are tightly regulated in countries like France and Netherlands. They are free in only a minority of advanced countries. even if these include some major players such as the US, Germany and, in a very limited sense, Japan. The situation in the UK is very complex with a semi-free system, where drug companies are free to set their own prices but cannot exceed a predetermined profit ceiling. Mark-up at both wholesaler and retail stages is formally adrmtted in most countries observed. Apart from the general drug prices, reimbursement price of insured drugs has been major policy concerns. Most countries reviewed in this study has exerted some control over reimbursement prices, but differ both in the way how and in the extent to which prices are adrmtted or fixed. Price fixing has been used in France and Japan. Some countries have transformed their system over time, particularly to move to reference pricing in the last decade. This mechanism has empowered the customer, and improved price competition on the market. Referring to the drug price policies in the advanced countries, this study makes some suggestions for the redirection of Korean price policy for reimbursement drug in health insurance as follows: to match appropriate policy tools to each policy goal: to maximize market mechanism through effective reimbursement price fixing which adrmts mark-ups in wholesaler and retail prices: to introduce reference pricing system in order to redirect patient`s demand with a financial incentive to choose the best-priced drugs and to save the finance of health insurance; and to strengthen surveillance and monitoring mechanism in the drug market.
Catalytic Hydrolysis of <i>p</i>-Nitrophenyl Esters in the Presence of Representative Ammonium Aggregates. Specific Activation of a Cholesteryl Nucleophile Bound to a Dialkylammonium Bilayer Membrane (1979)

Abstract Catalytic hydrolysis of p-nitrophenyl esters (acetate and nonanoate) by hydroxamate and imidazole nucleophiles was studied at 30 °C in the presence of aqueous aggregates of single-chain (hexadecyl), double-chain (didodecyl and dioctadecyl) and triple-chain (trioctyl) ammonium amphiphiles. These three types of ammonium salts give rise to very different aggregate morphologies. The rate constant of ester cleavage by the nucleophiles was enhanced several hundred folds in the presence of these hydrophobic aggregates. Simple long-chain nucleophiles possessed esterolytic reactivities which reflect the hydrophobic microenvironment of the respective aggregates: single-chain&lt;double-chain&lt;triple-chain. On the other hand, the cholesteryl ester of imidazolecarboxylic acid showed an especially high reactivity when bound to the didodecylammonium bilayer. Cholic acid-derived nucleophiles showed normal reactivity patterns. Apparently, specific binding of the cholesterol derivative to the bilayer is responsible for the unusual catalytic behavior.
Semantic Web Interaction through Trust Network Recommender Systems (2005)

In this paper, we present FilmTrust, a website that integrates Semantic Web-based social networks, augmented with trust, to create predictive movie recommendations. We show how these recommendations are more accurate than other techniques in certain cases, and discuss this technique as a mechanism of Semantic Web interaction.
<i>YABBY</i> Polarity Genes Mediate the Repression of <i>KNOX</i> Homeobox Genes in Arabidopsis (2002)

The YABBY (YAB) genes specify abaxial cell fate in lateral organs in Arabidopsis. Loss-of-function mutants in two early-expressing YAB genes, FILAMENTOUS FLOWER (FIL) and YAB3, do not exhibit vegetative phenotypes as a result of redundancy. Mutations in these genes result in the derepression of the KNOX homeobox genes SHOOTMERISTEMLESS (STM), BREVIPEDICELLUS, and KNAT2 in the leaves and in the partial rescue of stm mutants. Here, we show that fil yab3 double mutants exhibit ectopic meristem formation on the adaxial surfaces of cotyledons and leaf blades. We propose that in addition to abaxial specification, lateral organ development requires YAB function to downregulate KNOTTED homeobox genes so that meristem initiation and growth are restricted to the apex.
Multimedia Databases and Servers (1995)

Database technology is evolving to accommodate complex multimedia objects — data types that present unique challenges in the storage and movement of large time-dependent objects. The manipulation and analysis of these large and semantically rich objects require techniques far different from those used for alphanumeric databases. This paper presents multimedia server-based architectures based on massively parallel processor systems and an object-relational database management system. The transition from client-centric multimedia applications to a client/server environment is examined, and several applications are discussed that illustrate the use of multimedia database servers based on the object-relational model. Finally, this paper reviews the architecture of two scaleable multimedia servers that can support these applications: MoonBase, a database server with full content analysis capability for multimedia objects, and the audio/video server, a system-based file server that can operate within the MoonBase architecture.
Business rules in a service development and execution environment (2007)

In the current Web based enterprise systems the need of changes in these systems happens in periods shorter and shorter. Considering that some business logic portions are quite volatile and susceptible to the changes and other portions are quite stable and less susceptible to the changes, this paper introduces a model that can capture business changes and quickly implement them into computational systems. The model includes an approach for fast development and execution of services considering that the volatile portions of business logic can be externalized as business rules and the stable portions as Web services. It is proposed a framework for Web services composition based on business rules and service ontology. The framework provides support for business rules definition using a friendly language to the business analysts, for Web services discovery in the business rules definition time, and for making connection between the business rules and Web services in the service execution time. Business rules are modeled according to OMG's SBVR metamodel.
Navigating large virtual spaces (1996)

As important as navigation is to human performance in virtual worlds, it is an often overlooked problem in the design process. This article reports an experiment intended to show that real‐world wayfinding and environmental design principles are effective in designing virtual worlds that support skilled wayfinding behavior. The study measures participant performance on a complex searching task in a number of virtual worlds with differing environmental cues. The worlds are augmented with either a radial grid, a map, or both a grid and a map. The control condition provided no additional navigational cues. The results showed that navigational performance was superior under both map treatments as compared to the control and grid conditions. The grid was, however, shown to provide superior directional information as compared to the other conditions. The control condition provided the worst performance, with participants often becoming disoriented and experiencing extreme difficulty completing the tasks.
On the Implementation of Blind Interference Alignment With Single-Radio Parasitic Antennas (2016)

This paper studies the electronically steerable parasitic array radiator (ESPAR) antenna as a solution for beam pattern switching to implement blind interference alignment (BIA). The ESPAR antenna uses a single radio-frequency (RF) chain, and its beamforming is achieved by simply tuning the reactance loads of parasitic elements. Furthermore, ESPAR's beam pattern can be designed to enhance the received signal-to-noise ratio (SNR), thereby improving the performance of BIA. The focus of this work is the design of the ESPAR beam pattern to realize and improve BIA. In the first approach, each receiver ESPAR antenna dynamically selects the proper beam patterns from among the sector beam patterns, which are pre-designed to access different angular sectors with constant optimal antenna efficiency. We also propose a singular value decomposition (SVD) beamforming method, by means of the available channel state information at the receiver and a dynamic matching network for a high antenna efficiency. The simulation results illustrate the improvement of BIA with proposed methods, especially in the low and moderate SNR region, due to ESPAR's beamforming capability.
