Journals metadata: information about content (1999)

ABSTRACT Metadata is data about data, or information about content. It is important to have standard ways of describing content for efficient resource discovery on the world‐wide web, and to tie this in with information about people and rights to build the foundations for e‐commerce. The most significant emerging standard is the Dublin Core, which has recently stabilized its simple (minimum) set as DC 1.0. Various organizations (including Wiley) have already been exploring the use of Dublin Core tags in a number of implementations. Other initiatives are taking place to bring all metadata schemes within an overarching data model. As the industry responsible for managing content from commissioning through to authenticated release, publishing should play a major role in metadata creation and promulgation.
Project management in rapid application development (1995)

This work deals with some of the principles upon which rapid application development (RAD) projects are managed, based on recent case studies and published methods. It focuses particularly on the development team, and suggests themes that may underlie RAD principles. An approach to metrics in establishing the relationship between principles and benefits is discussed.
Putting the Infrared Heat on X-rays (1998)

Doctors would love to put an old workhorse—x-rays—out to pasture. Although x-rays are still an indispensable tool for diagnosing everything from broken pinkies to lung tumors, the energetic beams can damage DNA, posing a slight cancer risk. Infrared light, which can pass through tissue harmlessly, could bring a softer touch to medical imaging. But to turn it into a serious rival for x-rays, researchers need a simple way to compose an image from the few infrared photons that pass directly through tissue without getting scattered. In this issue of Science, a team from the University of Arizona in Tucson and the California Institute of Technology (Caltech) in Pasadena reports about a light-sensitive polymer that might do the job.
Prediction of Structural Effects of Trialkylsilyl Groups on Reactivity toward Nucleophilic Displacement at Silicon (1993)

Abstract A quantitative method of predicting reactivities of trialkylsilyl groups relative to Me3Si toward nucleophilic displacement at silicon has been established on the basis of statistical analyses of the rates of solvolysis for a comprehensive series of chlorosilanes in aqueous dioxane.
Wireless link scheduling for data center networks (2011)

Data Center Networks (DCNs) suffer from the congestions caused by unbalanced traffic distributions. Nevertheless, it is difficult to address such a challenge with the existent Ethernet-based DCN architecture. Wireless networking has been considered as a viable approach with a high potential to tackle the problem due to its flexibility. This paper presents Wireless Link Scheduling for Data Center Networks (WLS-DCN) to provide a feasible wireless DCN. More specifically, we propose a wireless DCN architecture as well as a scheduling mechanism. In our wireless scheduling, two different optimization objectives are considered, with one targeting the unbalanced traffic distribution and one maximizing the total network utility, under the constraints of limited wireless resources and co-channel interference. We propose two heuristics for the two problems and carry out extensive simulation study to validate the performance of our design. Our results demonstrate that WLSDCN can significantly improve the performance of DCN.
Marked Production of Ginsenosides Rd, F2, Rg3, and Compound K by Enzymatic Method (2007)

The hydrolysis of protopanaxadiol-type saponin mixture by various glycoside hydrolases was examined. Among these enzymes, crude preparations of lactase from Aspergillus oryzae, beta-galactosidase from A. oryzae, and cellulase from Trichoderma viride were found to produce ginsenoside F(2) [3-O-(beta-D-glucopyranosyl)-20-O-beta-D-glucopyranosyl-20(S)-protopanaxadiol], compound K [20-O-beta-D-glucopyranosyl-20(S)-protopanaxadiol], and ginsenoside Rd {3-O-[beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl]-20-O-beta-D-glucopyranosyl-20(S)-protopanaxadiol}, respectively, from protopanaxadiol-type saponin mixture in large quantities. Moreover, the crude preparation of lactase from Penicillium sp. having a high producing activity of ginsenoside Rh(1) (6-O-beta-D-glucopyranosyl-20(S)-protopanaxatriol) from protopanaxatriol-type saponin mixture gave ginsenoside Rd as a main product, ginsenoside Rg(3) {3-O-[beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl]-20(S)-protopanaxadiol}, and compound K from protopanaxadiol-type saponin mixture. The hydrolytic pathways of ginsenosides Rb(1), Rb(2), and Rc to ginsenosides Rd, Rg(3), and F(2), and compound K by crude preparations of four glycoside hydrolases were also studied. This is the first report on the enzymatic preparation of an intestinal bacterial metabolite, ginsenoside F(2), in quantity, and a considerable amount of a minor saponin, ginsenoside Rg(3), from a protopanaxadiol-type saponin mixture.
Bone regeneration adjacent to titanium dental implants using guided tissue regeneration: a report of two cases. (1990)

The biologic principle of guided tissue regeneration was applied to regenerate alveolar bone in conjunction with the placement of titanium dental implants. In one case, complete osseointegration of an implant was achieved by the placement of a Teflon membrane over an implant that had been inserted into an alveolus immediately following tooth extraction. In a second case, the same biologic principle was used to increase the volume (height and width) of a resorbed, edentulous alveolar ridge to provide adequate bone dimensions for implant installation. In both cases, the membranes appear to have prevented the repopulation of the wound area by cells other than those derived from surrounding bone tissue. These two different applications of the principle of guided tissue regeneration open new avenues for reconstructive osseous surgery.
Mass Spectrometry (1977)

Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Korean companies need to enhance Korean language capabilities for Filipino employee. South Korea has many successive experiences for e-learning. In this paper, we developed Learning Management System (LMS) for Philippines. LMS was implemented in JAVA, ASP and HTML. All lectures are stored in database managed by MS SQL-server.
A Simple Activation/Deactivation Prefetching Scheme for Chip Multiprocessors (2016)

Prefetching significantly reduces the memory latencies of a wide range of applications and thus increases the system performance. However, as a speculative technique, prefetching may also noticeably increase the number of memory accesses, which in turns may negatively impact on the main memory bandwidth consumption, performance, and power. Main memory bandwidth consumption is a critical resource especially in the context of current multicore processors since memory requests from all the cores, both prefetch and demand requests, compete among them in the access to the DRAM banks. Consequently, demand requests may be delayed hurting the system performance. This work proposes the Activation/Deactivation Policies (ADP) scheme for hardware prefetchers in multicore processors. This scheme relies on activation policies that turn on the prefetcher on a given core when it is expected that prefetches will improve the performance, and turn off the prefetcher of that core when it is foreseen that performance will be scarcely improved or not improved at all. The proposed mechanism effectively reduces the memory bandwidth requirements of some cores with respect to a typical always prefetching mechanism, so making available extra bandwidth to the co-runners. Results in a four-core processor show that ADP prefetching achieves similar performance ±2.5% as always prefetching, while significantly reducing the memory bandwidth consumed by use-less prefetches. Moreover, in some applications this reduction is as much as 50%. ADP prefetching is applicable to stream-based prefetchers, global-history-buffer delta correlation prefetchers, and PC-based stride prefetchers.
A general purpose virtual collaboration room (2003)

The general purpose virtual collaboration room (VCR) is an Internet based desktop groupware system that enables a group of remote individuals to flexibly and naturally conduct their collaborative teaching/learning/working without constraints on collaboration types, working styles, group scales, and system platforms. To cope with the complexity, a room metaphor, i.e., emulating a physical room and objects in it, is used as a framework of the system. System implementation becomes no more complex than the case of using one object by identifying associated objects in communication messages between a room server and clients. The VCR provides rich and effective support of awareness of the user, object, space, and their mutual relations. With the use of Java applets for system implementations, users can enter and use a VCR from any standard Java enabled Web browser.
Increase in Quinolone Resistance in a <i>Haemophilus influenzae</i> Strain Isolated from a Patient with Recurrent Respiratory Infections Treated with Ofloxacin (1999)

The increase in the level of quinolone resistance of Haemophilus influenzae clinical isolates during ofloxacin therapy of a patient with recurrent respiratory infections was investigated. The first isolate (MIC of ciprofloxacin of 2 microg/ml) and the second isolate (MIC of 32 microg/ml) belonged to the same clone, as shown by pulsed-field gel electrophoresis, and the increase in the resistance level was associated with a substitution in Ser-84 to Arg in the ParC protein. These results emphasize the potential risk of development of quinolone-resistant H. influenzae during fluoroquinolone therapy in patients with recurrent respiratory infection.
Stable stitching method for stereoscopic panoramic video (2018)

This paper proposes a stable method of generating a stereoscopic panoramic video with the omnidirectional stereo (ODS) format. Different from the traditional image stitching method which can only be applied to generate a monocular panorama, we adopt an optical flow‐based blending method to create two panoramas for binocular vision. In addition, traditional image stitching methods based on seam‐finding tend to cause the problem of temporal flicker. We address this problem by restricting the optical flow field of the new frame with its previous frame's optical flow field. Thus, the generated video is stable and out of temporal flicker. There are four key operations in our approach. First, we adopt the ODS format which is the basis of stereoscopic panorama. Second, we do effective exposure compensation, making the brightness of the two eyes' panoramas consistent. Third, we employ an optical flow‐based blending method to synthesis the final panorama effectively. Fourth, we take the previous frame's optical flow field as the restriction of the present frame's optical flow field to acquire a stable video. The final output videos can deliver a pleasant and impressive stereoscopic viewing experience to the audience when the audience watches the videos in the virtual reality headset.
Long term hemodialysis aggravates lipolytic activity reduction and very low density, low density lipoproteins composition in chronic renal failure patients (2009)

Despite hemodialysis duration, VLDL-LDL metabolism alterations are aggravated submitting patients to a greater risk of atherosclerosis.
Construction and Characterization of a Single-Cycle Chimeric Flavivirus Vaccine Candidate That Protects Mice against Lethal Challenge with Dengue Virus Type 2 (2008)

We have previously described a novel flavivirus vaccine technology based on a single-cycle, capsid (C) gene-deleted flavivirus called RepliVAX. RepliVAX can be propagated in cells that express high levels of C but undergoes only a single cycle of infection in vaccinated hosts. Here we report that we have adapted our RepliVAX technology to produce a dengue vaccine by replacing the prM/E genes of RepliVAX WN (a West Nile virus [WNV] RepliVAX) with the same genes of dengue virus type 2 (DENV2). Our first RepliVAX construct for dengue virus (RepliVAX D2) replicated poorly in WNV C-expressing cells. However, addition of mutations in prM and E that were selected during blind passage of a RepliVAX D2 derivative was used to produce a second-generation RepliVAX D2 (designated D2.2) that displayed acceptable growth in WNV C-expressing cells. RepliVAX D2.2 grew better in DENV2 C-expressing cells than WNV C-expressing cells, but after several passages in DENV2 C-expressing cells it acquired further mutations that permitted efficient growth in WNV C-expressing cells. We tested the potency and efficacy of RepliVAX D2.2 in a well-described immunodeficient mouse model for dengue (strain AG129; lacking the receptors for both type I and type II interferons). These mice produced dose-dependent DENV2-neutralizing antibody responses when vaccinated with RepliVAX D2.2. When challenged with 240 50% lethal doses of DENV2, mice given a single inoculation of RepliVAX D2.2 survived significantly longer than sham-vaccinated animals, although some of these severely immunocompromised mice eventually died from the challenge. Taken together these studies indicate that the RepliVAX technology shows promise for use in the development of vaccines that can be used to prevent dengue.
Ultrasonic mixer for paints and emulsions (1994)

In this paper a device for mixing various sedimented paints and other viscous fluids is described. The action principle of the device is based on the cascade concentration of ultrasonic flexural waves and next their conversion into longitudinal waves in mixed medium. Finally, the acoustical energy is focused along the linear focus inside the mixed liquid medium and results in producing a steep gradient of acoustical pressure which causes movement of the liquid. The opening of paint containers or their shaking is not necessary. This device can also be applied as a washer, emulgator and other similar purposes
Purification of Transplutonium Actinides Produced in Underground Thermonuclear Explosions (1967)

The study of heavy elements produced in underground thermonuclear explosions requires the separation of trace quantities of actinide elements from several hundred to several thousand grams of fused rock containing the products from about 1017 fissions. After the sample is pulverized and dissolved in HNO3, HClO4, and HF, fluoride insoluble salts are precipitated. These are redissolved, and the actinides and lanthanides are extracted into tributyl phosphate from a solution that is highly salted with Al(NO3)3. The actinides and lanthanides are back-extracted intc water and then extracted into di-2-ethylhexyl phosphoric acid. Recovery from di-2-ethylhexyl phosphoric acid is achieved by esterification with decanol. The actinides are separated from the lanthanides by elution from a cation-exchange resin column with an ethanol-hydrochloric acid solution. Individual actinides are separated by elution from a cation-exchange resin column with α-hydroxyisobutyric acid.
A Novel Loss of Function Mutation of <i>PCSK9</i> Gene in White Subjects With Low-Plasma Low-Density Lipoprotein Cholesterol (2006)

We discovered a novel inactivating mutation as well as some rare nonconservative amino acid substitutions of PCSK9 in white hypocholesterolemic individuals.
Fluorescence anisotropy of labeled F-actin: influence of divalent cations on the interaction between F-actin and myosin heads (1982)

The interaction between F-actin and soluble proteolytic fragments of myosin, heavy meromyosin and myosin subfragment 1 without ATP, has been studied by measuring the static anisotropy and the transient anisotropy decay of the fluorescent chromophore N-(iodoacetyl)-N'-(5-sulfo-1-naphthyl) ethylenediamine bound to F-actin. In the presence of Ca2+ ions, the mobility of the chromophore was strongly decreased by adding heavy meromyosin or myosin subfragment 1, and this conformation change of F-actin showed a strong cooperativity; that is, a very small amount of myosin heads induced the maximum anisotropy change. On the other hand, in the presence of Mg2+ ions, the addition of a small amount of myosin subfragment 1 or of heavy meromyosin increased the mobility of labeled F-actin that reached a maximum at a molar ratio of about 1/25 or 1/50, respectively. With further addition of myosin heads, the mobility of the labeled actin decreased. From these studies, one concludes that F-actin undergoes a conformation change by interacting with myosin heads, which depends on the nature of the divalent cations present in the solution.
Optimum maximum voltage angle and current total harmonic distortion of uninterruptible power supply on three level single phase photovoltaic - Wind power hybrid inverter (2012)

This paper presents a new topology of optimum maximum voltage angle and current total harmonic distortion (CTHD) of uninterruptible power supply (UPS) on three level single phase photovoltaic (PV) - wind power hybrid inverter. It consists of four main circuits; they are a hybrid controller circuit, a charger circuit, a pulse driver and full bridge circuit. Its main energy sources are a PV array and wind power generation. In this research, a new technique to optimize the CTHD is by changing maximum voltage angle of the three level waveform that created by a microcontroller PIC16F627A-I/P and searched the lowest CTHD. This inverter is completed by stand by UPS, when the main power source fails, the battery can power the inverter and the microcontroller controls the UPS transfer switch. The result shows that for lamp load of 10 W, the lowest CTHD is obtained when the maximum voltage angle is 134 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sup> .
EMODIN IN BUCKTHORN: A FEEDING DETERRENT TO PHYTOPHAGOUS INSECTS (1979)

Abstract Emodin, a mixture of anthraquinones, occurs in the Rhamnaceae and functions as a deterrent to foliage-feeding insects. There was little attack on foliage of Rhamnus alnifolia in wild stands compared with associated species of woody plants. Anthraquinones extracted from foliage of R . alnifolia were similar to purchased emodin in thin-layer chromatographic and infra-red spectroscopic analyses. Quantities of emodin in foliage samples were high in May, declining to low levels in August. Leaf powders, leaf extracts, and purchased emodin all showed feeding deterrent activity when mixed with artificial diets and assayed with gypsy moth larvae. Purchased emodin showed similar activity when sprayed on foliage of small cherry trees and assayed with eastern tent caterpillar larvae.
Fabrication of Microstructures of Extreme Structural Heights by Reaction Injection Molding (1989)

Abstract For the fabrication of microstructures with minimum lateral dimensions in the micrometer range and structural heights of up to several hundred micrometers a new microfabrication technique has been developed by the Karlsruhe Nuclear Research Center. The so-called LIGA method is based on a combination of deep-etch X-ray-lithography, electroforming and plastic molding. High-quality micromold inserts can be prepared by deep-etch X-ray lithography and electroforming allowing an arbitrary choice of cross section of the microstructures. By optimization of the process parameters of the reaction injection molding process using casting resins on a methyl methacrylate base it has been shown that a yield of 100% can be achieved. For molding microstructures without any flaws, the mold material has to be degassed, the cavity of the mold must be evacuated and the shrinkage due to polymerization has to be compensated by applying a holding pressure. With an internal mold release agent which is a special salt of an organic acid, cycle times of about 12 min have been achieved in the micromolding process step which are very much shorter than the exposure and development times in the direct lithographic production of microstructures. Such plastic structures can represent the final product or, if microstructures are to be made of metal, they are used as templates in a subsequent electroforming process. Depending on the geometrical configuration of the microstructures, either a metallic gate plate or an electrically conducting plastic layer are used as the electrode for electroforming.
Pulmonary arterial hypertension: classification, diagnosis and contemporary management (2006)

Positioned between the two sides of the heart and residing within the lungs, the pulmonary circulation has a central role in cardiopulmonary gas exchange and oxygen transport. Its central position also renders the pulmonary circulation prone to injury as a result of disorders affecting the heart, lungs or systemic circulation. An uncommon, but serious and potentially devastating chronic disorder of the pulmonary circulation is pulmonary hypertension, a haemodynamic abnormality of diverse aetiology and pathogenesis. Over the past decade, several advances have occurred in the understanding, classification and medical management of pulmonary hypertension.1 This article outlines the approach to the diagnosis of pulmonary arterial hypertension (PAH) and discusses the use of currently available drug treatments and surgical procedures for this condition. We searched the Cochrane Controlled Trials Register, PubMed and Medline (MESH terms: primary pulmonary hypertension and pulmonary arterial hypertension) for clinical trials, randomised controlled trials, meta-analyses, practice guidelines and reviews. We selected only studies on humans and articles written in English. Pulmonary hypertension was previously divided into primary and secondary categories; primary pulmonary hypertension described an idiopathic hypertensive vasculopathy exclusively affecting the pulmonary circulation, whereas secondary pulmonary hypertension was associated with a causal underlying disease process. The recent identification of a gene responsible for the inherited forms of this disease, along with the development of specific medical treatments and the refinement of surgical techniques, has prompted a revised classification of pulmonary hypertension. This classification distinguishes conditions that directly affect the pulmonary arterial tree from those primarily affecting the pulmonary venous system or respiratory structure and function2 (box 1). The term primary pulmonary hypertension has now more accurately been replaced by idiopathic PAH, or, when supported by genetic investigation, familial PAH; the term secondary pulmonary hypertension has been abandoned. ### Box 1: Classification of pulmonary arterial hypertension
