Better criterion screening for left ventricular hypertrophy by electrocardiogram with different purposes (2011)

According to the recommendations for the standardization and interpretation of the electrocardiogram (ECG) of AHA/ACCF/HRS declared in 2009, there are more than 30 criteria for diagnosing left ventricular hypertrophy (LVH). The sensitivity of the various criteria is generally quite low. However, the specificity of ECG in LVH could be 85 to 90%, acting as a strong predictor for cardiovascular events. To investigate the proper criteria in epidemiological screening with different purpose, 5209 qualified ECG out of 6830 people were selected from cross-sectional Handan eye study. Two criteria were chosen: (1) Sokolow-Lyon index, sum of SV1+RV5 or V6 ≥ 35 mm; (2) Cornell voltage duration product, men: (SV3+RaVL)×QRS duration ≥2440 ms; women: (SV3+(RaVL+8 mV))×QRSduration ≥ 2440 ms. The ECG-LVH group contains 829 individuals (12.18% of the cohort), including 607 by Sokolow-Lyon index and 278 by Cornell voltage duration product. After data estimation, we found that there were no statistical differences between ECG-LVH population and normal population. While evaluated these data in the group that have retinopathy without diabetes, the Sokolow-Lyon index and Cornell voltage duration product were statistically different with normal population (P= 0.023 and P= 0.014, respectively). We use the simple MiniMental State Examination (MMSE) to evaluated the mental status of the population and found that when the score was above 15, there was no statistically different between the positive and negative people in Sokolow-Lyon index (P= 0.135); however, in evaluated Cornell voltage duration product, there was statistical difference (P=0.001). When we evaluated the data associated with atherosclerotic factors, we found no differences in Cornell voltage-duration product; as for the Sokolow-Lyon index, the differences were shown in systolic blood pressure, total cholesterols and uric acid (P= 0.03, 0.04 and 0.04, respectively). Different criterion should be chosen for different purposes. For atherosclerotic screening or epidemiological survey of cardiovascular diseases, the Sokolow-Lyon index might be better. If we use the criterion for epidemiological ophthalmology such as our Handan eye study, both Sokolow-Lyon index and Cornell voltage duration product could be used. As for the evaluation of mental status and its relationship with the LVH risk factors, we might choose Cornell voltage duration product.

Safety Data of Injectable Nonanimal Stabilized Hyaluronic Acid Gel for Soft Tissue Augmentation (2002)

BACKGROUND Nonanimal hyaluronic acid gel was recently developed for soft tissue augmentation and volume expansion and has been shown to offer several advantages in comparison to other augmentation materials. There are rare reports of adverse events believed to be secondary to trace amounts of proteins in the hyaluronic acid raw material. OBJECTIVE To determine the safety profile of nonanimal stabilized hyaluronic acid gel (Restylane, Perlane, Restylane Fine Lines, Q-Med AB, Uppsala, Sweden) for soft tissue augmentation using a retrospective review of all adverse events data from Europe, Canada, Australia, South American, and Asia from 1999 and 2000. RESULTS Data from an estimated 144,000 patients treated in 1999 indicated the major reaction to injectable hyaluronic acid was localized hypersensitivity reactions, occurring in approximately 1 of every 1400 patients treated. In 1999 there was an adverse event reported for 1 of every 650 patients (0.15%) treated. These were temporary events that included redness, swelling, localized granulomatous reactions, bacterial infection, as well as acneiform and cystic lesions. For 2000 there was an estimated 262,000 patients treated with hyaluronic acid gel. The total number of adverse events was 144, corresponding to one adverse event for every 1800 patients (0.06%) treated. The major adverse event was again hypersensitivity, occurring in 1 of every 5000 patients treated. CONCLUSION According to the reported worldwide adverse events data, hypersensitivity to nonanimal hyaluronic acid gel is the major adverse event and is most likely secondary to impurities of bacterial fermentation. According to data from 2000, the incidence of hypersensitivity appears to be declining after the introduction of a more purified hyaluronic acid raw material.
Growth in the measurement-while-drilling sector continues (1991)

This book reports that the measurement while drilling (MWD) market is showing some of the most impressive growth in the oil field. Tremendous improvements in the reliability and capability of MWD tools have spurred the expansion of this market. During 1990, the worldwide MWD market expanded by 48%, rising from $250 million in 1989 to $370 million in 1990. The MWD market should expand 15-20% to exceed $430 million in 1991. Although an expansion of 15-20% is considered good, further growth will be impeded by the slowdown of drilling in the Gulf of Mexico. Total market growth should return to greater than 20% per year in 1992 and 1993. MWD technology is in the midst of a rapid adaptation phase, led by expansion of formation evaluation and other logs and by international expansion in long-reach directional and horizontal drilling. The formation evaluation-while- drilling market will have minimal impact on the size and growth of the wire line market. Customers will increasingly employ teams which include drilling and petrophysics personnel to make MWD purchase decisions. Integration of performance drilling systems including all bottom hole components will accelerate because of increases in automation and the need for cost reduction.

Realistic Database for Semiconductor Device Analysis (1998)

Abstract When one department performs extensive analysis, the need for common data within a database structure may be required. A realistic paperless database was developed to solve department needs. This database is carried out with the combination of a Client Module, Operation Module and Management Module. The Client Module includes on-line request for analysis, intensive query, retrieval of the analysis result with digital image and image processing. The Operation Module provides real-time digital data acquisition from the analysis equipment, which have the data types of image, text or graph and real-time data transmission to a dedicated server Digital Alpha 4100. The Management Module includes approval of the request for analysis from the Client Module, creation of reports about analysis results and statistical service for the subjects like failure modes in a device, operation time of equipment and so on. These modules allow multi-users to access the database through the Web on the Intranet. Our database can be also linked to the in-line database and the failure analysis with DRT SEM and physical analysis can become more effective with the use of in-line inspection data. This paper presents the framework of the database along with a technical description of the database implementation.
Parasite manipulation of host personality and behavioural syndromes (2012)

The past decades have seen mounting evidence that parasites alter their host's behaviour in ways that benefit transmission, based on differences in the expression of behavioural traits between infected and control individuals, or on significant correlations between trait expression and infection levels. The multidimensional nature of host manipulation has only recently been recognised: parasites do not target single host traits, but instead suites of interrelated traits. Here, I use recent research on animal personality (behavioural differences among individuals consistent across time and situations) and behavioural syndromes (correlations at the population level among distinct behavioural traits, or between the same trait expressed in different contexts) to provide a framework from which simple testable patterns of host behavioural changes can be predicted. Following infection, a manipulative parasite could (i) change the temporal consistency of its host's behavioural responses, (ii) change the slope of a host reaction norm, i.e. the way host behavioural traits are expressed as a function of an environmental gradient, or (iii) decouple two or more host behavioural traits and/or change the way in which they correlate with each other. Two case studies involving trematode parasites and their freshwater hosts are used to provide empirical illustrations of the above scenarios. These clearly illustrate the full richness of behavioural alterations induced by parasites, and how these effects would go unnoticed using the classical trait-by-trait comparisons of mean values between parasitised and non-parasitised individuals. However, the power of animal personality and behavioural syndromes to inform research on host manipulation by parasites will only be fully realised when underlying mechanisms are elucidated and linked to their phenotypic impacts.
Quantitative SPECT reconstruction using CT-derived corrections (2008)

A method for achieving quantitative single-photon emission computed tomography (SPECT) based upon corrections derived from x-ray computed tomography (CT) data is presented. A CT-derived attenuation map is used to perform transmission-dependent scatter correction (TDSC) in conjunction with non-uniform attenuation correction. The original CT data are also utilized to correct for partial volume effects in small volumes of interest. The accuracy of the quantitative technique has been evaluated with phantom experiments and clinical lung ventilation/perfusion SPECT/CT studies. A comparison of calculated values with the known total activities and concentrations in a mixed-material cylindrical phantom, and in liver and cardiac inserts within an anthropomorphic torso phantom, produced accurate results. The total activity in corrected ventilation-subtracted perfusion images was compared to the calibrated injected dose of [(99m)Tc]-MAA (macro-aggregated albumin). The average difference over 12 studies between the known and calculated activities was found to be -1%, with a range of +/-7%.
II. Differences between sires in their return interval analyses (1975)

Abstract Records were analysed for 41 sires used by the Auckland Livestock Improvement Association in the 1970 season. Each sire recorded at least 597 first inseminations, made on the day after semen collection and processing, with semen diluted in Caprogen and minimum dose rates of 2.5 million total sperm per insemination. The average conception rate (C. R. = 49‐day non‐return rate to first insemination) for Hereford sires (67.9) was significantly higher than for Jersey (61.8) or Friesian sires (59.3). There was a significantly higher incidence of short return intervals (1 to 17 days) among Friesian sires (7.6 v. 6.2%). C. R. and % normal returns (18 to 24 days) were negatively correlated (r = —0.98). The percentage of short return intervals was also negatively correlated with C. R. and was — 0.53, whereas between C. R. and long return intervals (25 to 49 days) it was only — 0.26. Correcting C. R. s for the percentage of short and/or long return intervals for individual sires did not alter their relative C. R. ranking. The results support the hypothesis that C. R. differences between sires are primarily the result of variation in fertilisation rates.
A 5.79-Gb/s Energy-Efficient Multirate LDPC Codec Chip for IEEE 802.15.3c Applications (2012)

An LDPC codec chip supporting four code rates of IEEE 802.15.3c applications is presented. After utilizing row-based layered scheduling, the normalized min-sum (NMS) algorithm can reduce half of the iteration number while maintaining similar performance. According to the unique code structure of the parity-check matrix, a reconfigurable 8/16/32-input sorter is designed to deal with LDPC codes in four different code rates. Both sorter input reallocation and pre-coded routing switch are proposed to alleviate routing complexity, leading to 64% input reduction of multiplexers. In addition, an adder-accumulator-shift register (AASR) circuit is proposed for the LDPC encoder to reduce hardware complexity. After implemented in 65-nm 1P10M CMOS process, the proposed LDPC decoder chip can achieve maximum 5.79-Gb/s throughput with the hardware efficiency of 3.7 Gb/s/mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and energy efficiency of 62.4 pJ/b, respectively.
An Effective Budget Management Framework for Real-Time Bidding in Online Advertising (2020)

Real-time bidding (RTB) has achieved great success and significantly improved the efficiency and transparency of online advertising. It allows advertisers to purchase ad impressions via auctions. Advertisers who adopt RTB always seek an optimal strategy of budget spending to reach as a wider range of audiences with a more sustainable impact as possible. Traditional bidding strategies, such as fixed bid and performance-based bid, easily lead to being either too aggressive (budgets wiped out too fast) or conservative (budget surplus exists at the end with low clicks), due to lack of optimal budget management. In this paper, we study the optimization of budget efficiency under the smooth delivery constraint for display advertising. We model the problem as a multi-constrained budget allocation optimization and use a heuristic algorithm to solve an approximate optimal budget allocation. The key to the solution is to determine the bidding function for each time slot. Here, we propose a piecewise bidding strategy to filter out the low-quality impressions, where each time slot has its own predicted click-through rate (pCTR) threshold - only when the pCTR of an impression is not lower than the threshold, will the campaign participate in the bidding. However, determining the pCTR threshold is challenging due to market uncertainty, we tackle this problem by modeling the distributions of pCTRs and market prices in each time slot. On this basis, we derive an optimal bidding function for each time slot to make the bid price more adaptable to its available budget. We conduct our experiments on a public real-world dataset and the results show that our proposed method performs the best in terms of various standard metrics (e.g., the number of clicks, cost-per-click) under a given budget comparing to the state-of-the-art baselines.
Recycling, Reuse and Rehabilitation of Mine Wastes (2011)

If we want to ensure a sustainable future for the human race, we must learn to prevent, minimize, reuse and recycle waste. Reuse of mine wastes allows their beneficial application, whereas recycling extracts resource ingredients or converts wastes into valuable products. Yet, today, many of the proposed reuse and recycling concepts for mine wastes are not economic. Consequently, the great majority of mine wastes are still being placed into waste storage facilities. Significant research efforts are required to develop cost-effective reuse and recycling options and to prevent the migration of contaminants from rehabilitated waste repositories in the long term.
Bond-selected bimolecular chemistry: H+HOD(4νOH)→OD+H2 (1990)

The reaction of HOD containing four quanta of O–H bond stretching vibration with H atoms produces OD fragments almost exclusively. Vibrational overtone excitation prepares HOD(4νOH) that reacts with H atoms formed in a microwave discharge. The endothermic reaction of water with hydrogen atoms does not occur for ground vibrational state water but proceeds at roughly the gas kinetic collision rate for the vibrationally excited molecule. The production of OD fragments from HOD(4νOH) in the reaction is at least two orders of magnitude more efficient than the production of OH, indicating very selective reaction of the vibrationally excited bond.
Transcellular translocation of<i>Campylobacter jejuni</i>across human polarised epithelial monolayers (1999)

The mechanisms whereby Campylobacter jejuni translocates across the host intestinal epithelium are not yet understood and the transepithelial route remains undefined. During C. jejuni translocation, the transmonolayer electrical resistance (TER) across polarised monolayers of Caco-2 cells is not affected and the penetration of [(14)C]inulin across the monolayers does not increase. Over 24 h, however, bacteria damage the monolayer integrity, causing a decrease in the TER. These results support C. jejuni translocation through the cytoplasm of invaded cells (transcellular) rather than via intercellular spaces (paracellular).
Conserved Filamentous Prophage in <i>Escherichia coli</i> O18:K1:H7 and <i>Yersinia pestis</i> Biovar orientalis (2002)

Microbial virulence is known to emerge by horizontal gene transfer mechanisms. Here we describe the discovery of a novel filamentous prophage, designated CUS-1, which is integrated into the chromosomal dif homologue of the high-virulence clone Escherichia coli O18:K1:H7. An homologous chromosomal element (CUS-2) in Yersinia pestis biovar orientalis is integrated at the same relative location as CUS-1; both lysogenic E. coli and Y. pestis strains produce particles with properties expected of single-stranded DNA virions. CUS(phi) is epidemiologically correlated with the emergence of K1 strains with increased virulence and with the Y. pestis biovar responsible for the current (third) plague pandemic.
Body composition techniques and the four-compartment model in children (2000)

The purpose of this study was to compare the accuracy, precision, and bias of fat mass (FM) as assessed by dual-energy X-ray absorptiometry (DXA), hydrostatic weighing (HW), air-displacement plethysmography (PM) using the BOD POD body composition system and total body water (TBW) against the four-compartment (4C) model in 25 children (11.4 +/- 1.4 yr). The regression between FM by the 4C model and by DXA deviated significantly from the line of identity (FM by 4C model = 0.84 x FM by DXA + 0.95 kg; R(2) = 0.95), as did the regression between FM by 4C model and by TBW (FM by 4C model = 0. 85 x FM by TBW - 0.89 kg; R(2) = 0.98). The regression between FM by the 4C model and by HW did not significantly deviate from the line of identity (FM by 4C model = 1.09 x FM by HW + 0.94 kg; R(2) = 0. 95) and neither did the regression between FM by 4C (using density assessed by PM) and by PM (FM by 4C model = 1.03 x FM by PM + 0.88; R(2) = 0.97). DXA, HW, and TBW all showed a bias in the estimate of FM, but there was no bias for PM. In conclusion, PM was the only technique that could accurately, precisely, and without bias estimate FM in 9- to 14-yr-old children.
Purification and Characterization of a Fibrinolytic Enzyme form Bacillus sp. KDO-13 Isolated from Soybean Paste (2001)

A microorganism producing fibrinolytic enzyme was isolated from Korean traditional soybean paste and identified as Bacillus sp. KDO-13. The fibrinolytic enzyme was purified to homogeneity by ammonium sulfate fractionation, ion-exchange chromatography on DEAE-celluose, and gel chromatography on Sephadex G-100 of the culture supernatant of Bacillus sp. KDO-13. The molecular weight of the purified enzyme was estimated to be 44,000 by SDS-PAGE. The optimum pH and temperature for the enzyme activity were pH 8.0 and 50°C. respectively. The enzyme activity was relatively stable at pH 7.0-9.0 and temperature below 50°C. The activity of the enzyme was inhibited by Al 3- and Hg 2- , but activated by Co 2+ and Ni 2+ . In addition, the enzyme activity was potently inhibited by EDTA and o-phenanthroline. The purified enzyme could completely hydrolyze a fibrin substrate within 6 h in vitro, and had a low K m value for fibrin hydrolysis. It was concluded that the purified enzyme was a metalloprotease with relatively high specificity for fibrinolysis, and thus, could be applied as an effective thrombolytic agent.
An Overview on Quantum Computing as a Service (QCaaS): Probability or Possibility (2016)

Cloud computing is a worldwide classical system. Quantum computing is theoretical concept still in experimental review. Where cloud system is facing vulnerability in security, backup, processing and locality, there quantum computing shows a strong solution to overcome it. Most researchers are optimistic in quantum computing that it will improve cloud system. But to associate physics based subatomic computing system with software based cloud system is not an easy option. Our paper will show all the major advantages and disadvantages of quantum computing in the perspective to integrate it with cloud system. And review some recent progress with some foremost doubtful future aspects of quantum cloud computing. Also we will review the reality of quantum computation and internet system in applied viewpoint until present.
Coreless Electromagnetic Coupling-Based Drillstem Telemetry Using Dual Electronic Gauges (2007)

Summary A coreless electromagnetic coupling-based telemetry system for well-test data involving a full-bore drillstem test apparatus has been developed. This system allows the retrieval of formation pressures and temperatures above and below a tester valve by means of a wireline-conveyed electronic gauge and a permanently installed gauge. A wireline-deployed coreless electromagnetic proximity sonde is put into the well to transfer the data using time-division frequency transmission technology in the "Synchronization-Pressure-Low-Temperature-Low" mode on a single-core wired-armored cable. The coded pulse data are modulated on DC power signals. The surface processor uses a double-counter synchronization method to measure signal frequencies to eliminate ±1 most significant bit (MSB) error. Then a simplified algorithm is proposed, based on least-squares curve fitting and dimensionreduction methods, for computing actual temperatures and pressures for analysis of well-testing data. The proposed system is calibrated for temperatures up to 125°C and pressures up to 70 MPa with a pressure accuracy of 0.1% full scale (FS) and temperature accuracy of ±0.5°C. This approach combines the advantages of drillstem testing and wireline formation testing and has been successfully applied to onshore well testing.
