Multislice dark‐blood carotid artery wall imaging: A 1.5 T and 3.0 T comparison (2006)

Multislice carotid wall imaging at 3.0 T with IOSB and REX-DIR benefits from improved SNR and CNR relative to 1.5 T, and allows for higher spatial resolution carotid artery wall imaging.
Prioritization and transport in the ADTV digital simulcast system (1992)

A technical overview of the prioritization and transport in the advanced digital television system (ADTV) is provided. ADTV incorporates an efficient MPEG-compatible compression algorithm at its central core, with application-specific data prioritization and transport features added as separable layers. The compression process is based on a 1440*960 HDTV format, producing a selectable bit-rate in the region of 15-20 Mb/s. The data prioritization layer of ADTV achieves robust delivery over an appropriate two-tier modem by separating compressed video data into high- and standard-priority bit-streams with appropriate bit-rates. These prioritized data are then formatted into fixed-length cells with appropriate data-link-level and service-specific adaptation-level headers.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

E‐commerce policies and customer privacy: a longitudinal study (2000‐2010) (2012)

Purpose The present research is an updated and expanded continuation of an article by Parayitam et al. from 2008. The purpose of this study is to examine several internet policies and whether the communication of these policies to the customer has significantly changed during a ten year period. Design/methodology/approach The study defines published policies of how a company operates with respect to different factors. The policies examined are privacy, security, shipping, returns, and warranty. Each of the policies described above were then rated as per the rating scale defined by the authors. The 525 e‐commerce sites studied were divided into service and product sites, respectively. The e‐commerce sites were also separated into 28 industry groups. The data were also collected on some of the other factors that were important in this study. Findings E‐commerce companies do not fully inform their customers. The results showed no significant relationships between the policy ratings and any of the other factors taken into account. Research limitations/implications The net incomes collected were the companies' entire income, not exclusively from online sales. The present study used an unbalanced sample size consisting of more product sites than service sites. Practical implications People doing business over internet with e‐commerce companies need to read the privacy policy carefully and should be aware of how their information will be used by the e‐commerce companies. Originality/value The study provides valuable information about e‐commerce companies in communicating their customer service policies and very little changes have taken place in the last ten year period.

The Japp–Klingemann reaction has been employed to prepare six new tryptamines. Data on the intermediate phenylhydrazones, β-carbolines, and tryptamine carboxylic acids are presented. Syntheses of 5-methyl-, 6-methyl-, 5,5-dimethyl-, and 5,6-dimethyl-2-oxopiperidine-3-carboxylates are described.
A convenient method for the treatment of chronic copper poisoning in sheep using subcutaneous ammonium tetrathiomolybdate (1988)

Effective control of copper poisoning in sheep was obtained by the subcutaneous injection of ammonium tetrathiomolybdate. Three doses, each of 3.4 mg/kg bodyweight, were given on alternate days. This treatment caused a substantial reduction in liver copper content and in liver damage. It also decreased the mortality rate in animals that had developed the haemolytic crisis. The subcutaneous route is as effective as the intravenous route and is more convenient. No adverse side-effects of the treatment were observed.
특집 : 한국 미디어산업의 글로벌화 ; 글로벌 미디어시장 구조의 변화와 대응전략 방향 (2011)

글로벌 자유무역 체제 환경에서 국내 미디어 기업들이 기존의 글로벌 미디어 기업들에 대응하기 위해서는 미국계 글로벌 미디어 기업들이 채택했던 방식보다는 제3의 모델을 탐색할 필요성이 있다. 국내 시장 규모를 감안한다면 내부적으로 콘텐츠 기획, 투자, 제작, 유통에 이르는 다양한 영역의 리스크를 감당할 수 있는 사업자가 다수로 존재하기는 어렵다. 따라서 규모의 경제를 내부적으로 뒷받침하지 못하는 현실을 감안하여 국내 미디어 기업이 생산하는 전문적 영역의 콘텐츠를 중심으로 지역별, 장르별로 제한적인 글로벌화를 추진하는 것이 보다 효율적일 수 있을 것이다. 지역별로는 아시아 시장 중심으로 시장을 확대하여 규모의 경제 효과를 확보할 수 있게 하는 것이며 장르별로는 아시아를 포함한 세계 시장 내에 틈새장르로서 한류의 프로그램 유통을 확대하는 방식이다. 이와 같은 이중적 가치 모델을 기반으로 국내 미디어 기업들이 보다 양질의 콘텐츠를 기획, 투자할 수 있는 인프라 강화가 가장 중요한 요인으로 평가된다.
Anaplastic Large-Cell Lymphoma, T-/Null-Cell Type (2006)

Anaplastic large-cell lymphoma, T-/null-cell type (ALCL), is a rare disease that has only been well characterized for two decades. Despite this, the biology of ALCL is better understood than that of many other more common variants of lymphoma. This review focuses on the pathophysiology, clinical presentation, and therapy of ALCL, including stem cell transplantation. In particular, the text emphasizes how novel prognostic features and the evolving understanding of the biology of this disease will influence treatment selection and drug development.
Recombinant immune interferon inhibits leukemic cell growth by a monocyte-macrophage-mediated mechanism. (1985)

We have investigated direct and monocyte-macrophage (Mono/M phi)-mediated indirect effects of recombinant immune interferon (IFN-gamma) on the growth of established leukemic cell lines (K562, KG1, ML1, HL60, U937, and THP1). The direct antiproliferative effects of IFN-gamma on these leukemic cells were mild or negligible, when estimated by 3H-thymidine incorporation. Indirect effects were assessed by the growth pattern of leukemic cells cocultured with Mono/M phi that were pretreated with INF-gamma. While the leukemic cell growth was slightly suppressed by untreated Mono/M phi, this suppression was significantly augmented by the treatment of Mono/M phi with IFN-gamma (10-10,000 U/ml). In addition, the indirect effects of IFN-gamma on leukemic cell growth were examined at different stages of maturation of Mono/M phi. The augmentation of cytotoxicity was detected only when mature Mono/M phi were treated with INF-gamma. This suggests that IFN-gamma acts on tissue macrophages and augments their cytotoxicity against leukemic cells.

Adult Ciliary Epithelial Cells, Previously Identified as Retinal Stem Cells with Potential for Retinal Repair, Fail to Differentiate into New Rod Photoreceptors (2010)

The ciliary margin in lower vertebrates is a site of continual retinal neurogenesis and a stem cell niche. By contrast, the human eye ceases retinal neuron production before birth and loss of photoreceptors during life is permanent and a major cause of blindness. The discovery of a proliferative cell population in the ciliary epithelium (CE) of the adult mammalian eye, designated retinal stem cells, raised the possibility that these cells could help to restore sight by replacing lost photoreceptors. We previously demonstrated the feasibility of photoreceptor transplantation using cells from the developing retina. CE cells could provide a renewable source of photoreceptors for transplantation. Several laboratories reported that these cells generate new photoreceptors, whereas a recent report questioned the existence of retinal stem cells. We used Nrl.gfp transgenic mice that express green fluorescent protein in rod photoreceptors to assess definitively the ability of CE cells to generate new photoreceptors. We report that CE cells expanded in monolayer cultures, lose pigmentation, and express a subset of eye field and retinal progenitor cell markers. Simultaneously, they continue to express some markers characteristic of differentiated CE and typically lack a neuronal morphology. Previously reported photoreceptor differentiation conditions used for CE cells, as well as conditions used to differentiate embryonic retinal progenitor cells (RPCs) and embryonic stem cell-derived RPCs, do not effectively activate the Nrl-regulated photoreceptor differentiation program. Therefore, we conclude that CE cells lack potential for photoreceptor differentiation and would require reprogramming to be useful as a source of new photoreceptors.
Synthesis of Bimetallic Nanoshells by an Improved Electroless Plating Method (2005)

In the Letter, we demonstrate an improved electroless plating method for the synthesis of bimetallic shell particles. The procedure involves a combination of surface reaction, seeding growth, and removal of supporting cores. We modified ammonical AgNO3 in ethanol with a controlled amount of HCHO in the seeding process and a uniform and relatively dense coverage of silver nanoparticle seeds on colloid cores was achieved. Following the second kind of metal plating, we extended this method to prepare continuous bimetallic core-shell and hollow particles with a submicrometer diameter. The morphologies of the bimetallic Cu/Ag and Pt/Ag particles were studied with transmission electron microscopy and scanning electron microscopy, and their crystallinity and chemical composition were confirmed by X-ray diffraction. The prepared materials may be of applied value in areas such as catalysis, optics, and plasmonics.
Reliability of flexible thin-film embedded resistors and electrical characterization of thin-film embedded capacitors and inductors (2002)

The High Density Electronics Center (HiDEC) at the University of Arkansas is working with the Sheldahl MCM-L Consortium and Rensselaer Polytechnic Institute to develop low-cost embedded resistors, capacitors, and inductors in flexible polyimide film under a DARPA contract. The ability to remove discrete devices from the surface of PCB boards and MCMs and place them into a flexible film would be a breakthrough for MCM technology. Along with eventually using these films as free standing structures, comes advantages such as increased surface density, increased interconnect reliability, low weight, and low cost. The first part of this paper addresses the reliability of the resistor devices. This preliminary evaluation is focused on the processing of films consisting of polyimide layered with CrSi as a resistive material and copper for metallization. A test vehicle incorporating a full range of standard resistor values, with characterization and reliability structures, was used in this evaluation. Temperature, voltage, and moisture sensitivities were determined through temperature/bias, temperature/humidity, and thermal shock stresses. The mechanical dependability was evaluated using thermal shock cycling, and the power handling capability was determined from power cycling stress and power dissipation tests. The second part of the paper discusses the development and processing techniques used to make flexible thin film passive capacitors and inductors. The test vehicle was designed using a range of standard values of capacitors, inductors, and tuned circuits. Electrical characterization of the flexible thin film devices was performed up to 1.8 GHz. The extracted model parameters for the capacitors and inductors are reported.
Construction of Bayesian classifiers with GA for response modeling in direct marketing (2009)

In this paper, a Bayesian classifier for modeling consumer response to direct marketing is constructed based on a novel genetic algorithm (GA). To evaluate the performance of this model, we test it with a large amount of validation data of direct marketing and compare the results with other benchmark methods, including recency-frequency-monetary (RFM) analysis, Chi-Square automatic interaction detector (CHAID), logistic regression (LR) and so on. The results demonstrate the superiority of this model over the others in terms of accuracy of prediction and interpretable of results. Recently, it has been adopted by a credit card company to effectively handle business problems.
Estimation of the impact of noncompliance on pharmacokinetics: an analysis of the influence of dosing regimens (2008)

For equivalent doses for each drug, the longer acting preparation of risperidone, but not oxybutynin, is pharmacokinetically more forgiving of noncompliance than the shorter acting counterparts. Further analysis is required to confirm whether these observations are valid clinically.
Characterization of <i>de novo</i> transcriptome for waterhemp (<i>Amaranthus tuberculatus</i>) using GS‐FLX 454 pyrosequencing and its application for studies of herbicide target‐site genes (2010)

These results demonstrate the enormous value of 454 sequencing for gene discovery and polymorphism detection in a major weed species and its relatives. Furthermore, the merging of the 454 transcriptome data with results from a previous whole genome 454 sequencing experiment has made it possible to establish a valuable genomic resource for weed science research.
Herpesviruses that Infect Fish (2011)

Herpesviruses are host specific pathogens that are widespread among vertebrates. Genome sequence data demonstrate that most herpesviruses of fish and amphibians are grouped together (family Alloherpesviridae) and are distantly related to herpesviruses of reptiles, birds and mammals (family Herpesviridae). Yet, many of the biological processes of members of the order Herpesvirales are similar. Among the conserved characteristics are the virion structure, replication process, the ability to establish long term latency and the manipulation of the host immune response. Many of the similar processes may be due to convergent evolution. This overview of identified herpesviruses of fish discusses the diseases that alloherpesviruses cause, the biology of these viruses and the host-pathogen interactions. Much of our knowledge on the biology of Alloherpesvirdae is derived from research with two species: Ictalurid herpesvirus 1 (channel catfish virus) and Cyprinid herpesvirus 3 (koi herpesvirus).
Observer variability in metameric color matches using color reproduction media (1997)

Standard color-matching functions are designed to represent the mean color-matching response of the population of human observers with normal color vision. When using these functions, two questions arise. Are they an accurate representation of the population? And what is the uncertainty in color-match predictions? To address these questions in the dual context of human visual performance and cross-media reproduction, a color-matching experiment was undertaken in which twenty observers made matches between seven different colors presented in reflective and transmissive color reproduction media and a CRT display viewed through an optical apparatus that produced a simple split-field stimulus. In addition, a single observer repeated the experiment 20 times to estimate intra-observer variability. The results were used to evaluate the accuracy of three sets of color-matching functions, to quantify the magnitude of observer variability, and to compare intra- and inter-observer variability in color-matching. These results are compared with various techniques designed to predict the range of color mismatches. The magnitude of observer variability in this experiment also provides a quantitative estimate of the limit of cross-media color reproduction accuracy that need not be exceeded. On average, the differences between matches made by two different observers was approximately 2.5 CIELAB units. © 1997 John Wiley & Sons, Inc. Col Res Appl, 22, 174–188, 1997

Effect of coumarins on HL-60 cell differentiation. (2000)

Twenty-eight coumarins, including 7 furocoumarins, were examined for their activity of induction of terminal differentiation of human promyelocytic leukemia cells (HL-60) by nitro blue tetrazolium (NBT) reducing, nonspecific esterase, specific esterase and phagocytic activities. Esculetin, nordalbergin, 6,7-dihydroxy-4-methylcoumarin and imperatorin had strong activity among the coumarins examined. HL-60 cells treated with these coumarins differentiated into mature monocyte/macrophage. The structure-activity relationship established from the results revealed that 6,7-dihydroxy moiety had an important role in the induction of differentiation of HL-60.
Design concepts for a mechanically refrigerated 13 K superconducting magnet system (1983)

The construction of small superconducting magnets operating in the 12 to 14 K temperature range without use of supplemental cryogenic fluids is of interest for a number of applications. This requirement can be satisfied for peak fields of up to 3.3 T using Nb <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> Sn superconductor and cooling by means of a close-coupled two stage refrigerator. In order to reduce lead losses, the current must be minimized. Conduction-cooled leads, heat stationed at 14, 70 and 300 K have been designed. Operating at 40 A, they impose 5 and 1 W heat loads (respectively) on the first and second stages of the CTI- 1020 refrigerator capable of absorbing 30 and 2.5 W (respectively) at the 70 and 13 K heat stations. The refrigerator is a relatively inexpensive "off-the-shelf" item.
Signal transduction mechanisms of C1q-mediated superoxide production. Evidence for the involvement of temporally distinct staurosporine-insensitive and sensitive pathways (1992)

C1q, a plasma glycoprotein and the recognition component of the classical complement pathway, interacts with specific cells of the immune system resulting in the enhancement of cell function. For example, interaction of C1q with its cell-surface receptor on neutrophils induces the activation of the respiratory burst, a finding previously documented using a chemiluminescent assay to detect oxygen radical formation. In an alternative approach we have now used a modified cytochrome c reduction assay to characterize C1q-mediated production of superoxide anion (O2-) in more detail. C1q coated to microtiter wells induced O2- release, which occurred microtiter wells induced O2- release, which occurred after a lag period of 10 to 20 min, and was then sustained over approximately 1 h. O2- production could be triggered by the purified pepsin-resistant, collagen-like fragment of C1q, but not by mannose-binding protein and pulmonary surfactant protein A, proteins that also contain collagen-like domains. Concentrations of C1q which promoted a vigorous O2- generation did not induce release of neutrophil primary granules and caused little or no secondary granule release. Investigation of the biochemical events mediating C1q stimulated O2- production by neutrophils revealed that the response invoked two biochemical pathways with distinct sensitivities to previously described inhibitors. A role for Ca2+ in initiation of the response was suggested by the inhibitory effect of EGTA, the calmodulin antagonist W7, and the intracellular Ca2+ chelator BAPTA. The protein kinase inhibitor staurosporine did not inhibit the induction of the response, but did block that component of the response occurring after approximately 30 min. Neither phase of C1q-mediated O2- production was inhibited by pertussis toxin, a strong inhibitor of the G-protein-coupled FMLP-mediated response. In summary, C1q-triggered O2- production is relatively unique both in terms of the kinetics of the response and the biochemical pathways evoked. These data support the hypothesis that more than one biochemical pathway induced by ligand-receptor interaction can activate the neutrophil NADPH oxidase.
