Adaptive multi-round scheduling strategy for divisible workloads in grid environments (2009)

Scheduling is the key to divisible workload execution. UMR (Uniform Multi-Round) algorithm potentially performs near optimal by improving overlap of communication and computation. However, it is questioned how a static schedule works effectively in dynamic grid environment. The paper proposes an adaptive divisible workload scheduling system, which can adjust the schedule in a proactive way. An adaptive UMR-based multi-round algorithm (called AUMR) is presented and evaluated. In AUMR, if the run-time resource monitor notifies the scheduler of any resource changes, the scheduler will evaluate its impact and adjust the schedule if necessary. The experiment results show a considerable performance improvement by AUMR in dynamic grid environment.
Albumin Recovery Enhancement in Membrane Plasma Fractionation using Pulsatile Flow (1991)

In therapeutic plasmapheresis using cascade filtration, it is important to maximize albumin recovery while rejecting as many gamma-globulins as possible. Several membrane fractionation techniques were investigated using fresh bovine and human plasma and cellulose acetate filters (PF 100, AKZO). In dead end mode the sieving coefficients were found to decrease as transmembrane pressure increased. This was due to membrane plugging during the course of filtration after about 20 minutes which lead to a rapid increase in transmembrane pressure. In single pass mode the albumin recovery factor generally remains around 40% since the permeate flux is much less than the inlet flow. When strong pulsations (4 to 6 Hz) were superposed on the inlet plasma flow in single pass mode, the albumin sieving coefficient remained at about 0.95 while the permeate flux was increased by 106%. As a result a recovery factor of more than 80% could be sustained for at least 90 minutes without membrane plugging. Therefore pulsatile flow plasma fractionation seems to be an interesting approach to combine continuous operation with high albumin recovery.
Tilted-Component Telescopes Part I: Theory (1970)

A simple but unorthodox application of third-order aberration theory enables one to design a simple form of highly corrected off-axis telescope. Known as the tilted component telescope, with subclasses (a) Schiefspiegler, (b) Yolo, and (c) catadioptric herschelian (CHT), is it distinguished by axially symmetric components that frequently require only spherical curvature.
Stock market trend prediction using ARIMA-based neural networks (2002)

We develop a prediction system useful in forecasting mid-term price trend in Taiwan stock market (Taiwan stock exchange weighted stock index, abbreviated as TSEWSI). The system is based on a recurrent neural network trained by using features extracted from ARIMA analyses. By differencing the raw data of the TSEWSI series and then examining the autocorrelation and partial autocorrelation function plots, the series can be identified as a nonlinear version of ARIMA(1,2,1). Neural networks trained by using second difference data are shown to give better predictions than otherwise trained by using raw data. During backpropagation training, in addition to the traditional error modification term, we also feedback the difference of two successive predictions in order to adjust the connection weights. Empirical results shows that the networks trained using 4-year weekly data is capable of predicting up to 6 weeks market trend with acceptable accuracy.
Tolerance and contact sensitivity to DNFB in mice. I. In vivo detection by ear swelling and correlation with in vitro cell stimulation. (1974)

Tolerance and sensitivity to a potent contact sensitizer were studied in vivo and in vitro. Contact hypersensitivity to 2,4-dinitro-1-fluorobenzene (DNFB) was induced in BALB/c mice by two daily paintings with 0.5% DNFB. The degree of hypersensitivity was assayed 4 days after the second painting by measuring the increments of ear thickness 24 hr after challenging the ears with 0.2% DNFB. Ear swelling was maximum at 24 hr and the histology was compatible with delayed type hypersensitivity. Specific tolerance to DNFB was produced by a single i.v. injection of 15 mg of 2,4-dinitrobenzene-1-sulfonic acid sodium salt (DNB·SO 3 Na) 7 days prior to sensitization. DNB SO 3 Na given 2 days before, the same day as or 1 or 3 days after sensitization resulted in only partial unresponsiveness. Tolerance and sensitization were also measured by in vitro stimulation of DNA synthesis in cultured lymphoid cells. Lymph node cells taken 5 days after sensitization were specifically stimulated by DNP-BSA (but not by BSA) in vitro as assayed by increase of 3 H-thymidine uptake. This response was dependent on the presence of T cells. Cells from non-sensitized mice responded poorly to DNP-BSA stimulation. Lymph node cells from tolerant mice responded 71 to 87% less than did sensitized cells. The results are discussed in terms of possible mechanisms of tolerance. In the context of this model of contact sensitivity, this appears to be tolerance at the T-cell level.
Synthesis of 3-aryl-2-thiohydantoin- and 3-arylhydantoin-5-acetic acids and screening of some of their pharmacological properties. (1976)

Seven 3-aryl-2-thiohydantoin-5-acetic acids were obtained from asparagine and arylisothiocyanates. After desulphuration of these compounds by monochloroacetic acid seven 3-arylhydantoin-5-acetic acids were obtained. The structure of these compounds was confirmed by their IR spectra. None of the compounds neither showed the anticonvulsive activity in the electroconvulsions and pentylenetetrazole tests nor inhibited the prostaglandin synthetase.
The MiniWiD-Coater. III. Effect of Application Temperature on the Dissolution Profile of Sustained-Release Theophylline Pellets Coated with Eudragit Rs 30 D (1993)

Theophylline pellets were coated with Eudragit RS 30 D in a miniature fluid-bed pan coater called MiniWiD developed recently. The dispersions were plasticized with varying amounts of triethyl citrate (TEC), dibutyl phthalate (DBP), and polyethylene glycol 6000 (PEG) and applied at different temperatures ranging from 25 to 45 °C. Theophylline release was tested by dissolution using the USP Apparatus 2 (paddle) in 0.1 N hydrochloric acid under sink conditions over 6 hours.At a coating level of 4 % (0.7 mg/cm2) sustained-release profiles were obtained from dispersions plasticized with TEC or DBP. By reducing the amount of plasticizer from 20 to 10%, films with higher permeabilities were obtained. This effect was compensated by tempering the pellets at 50 deg;C for 24 hours. The coating temperature had little effect on the dissolution profiles of TEC-plasticized films and no effect on films with DBP.Coatings plasticized with 20% PEG were applied at temperatures ranging from 25 to 45 °C. These films required a coating level of about 18 % (3.3 mg/cm2) to provide comparable sustained-release properties. In contrast to DBP and TEC, a strong influence of the coating temperature on the release rates was observed in which higher temperatures led to slower release rates. This behavior can be explained by the minimum film-forming temperature (MFT). Since PEG does not lower the MFT of Eudragit RS 30 D, the application of these films below the MFT of 45 °C is associated with a lower degree of film formation.
Video-based signature verification and pen-grasping posture analysis for user-dependent identification authentication (2012)

This article proposes a video-based identification authentication framework via signature verification and pen-grasping posture analysis. The authors consider the case of using a camera instead of a pressure-sensitive tablet to acquire signatures. The proposed reliable verification method is useful when pressure-sensitive digitising tablets are not available. In addition, the authors can acquire more information in addition to the trajectories of the signature in video-based handwritten signature verification. The entire writing process and the pen-grasping posture are personalised features that cannot be easily imitated and forged. The authors analyse the signature trajectories using curvelets and the pen-grasping posture using modified motion energy images to perform user-dependent identification authentication. The proposed system is able to achieve both low false-rejection rates and low false-acceptance rates for database containing both unskilled and skilled imitation signatures.
Characterization of coplanar waveguide open end capacitance-theory and experiment (1994)

The theory, numerical analysis, analytical approximate formula, measurement technique, and characteristic curves were presented in this paper for the characterization of coplanar waveguide open end capacitance. A novel variational equation was proposed in terms of the scalar potential on the slot aperture and was solved by applying the finite element method. With the available analytical Green's function and exact integration formulas in the space domain, this approach was found to be quite efficient and suitable for analyzing the coplanar waveguide discontinuity problems-even with more complicated geometrical configurations. Numerical results were compared to those obtained numerically and experimentally in previous literature, but did not correlate very well. An analytical formula under narrow-slot assumption was thus derived to render a verification of numerical results. Measurement by utilizing the resonance method were also made and the experimental data confirmed the validity of our theory. The relationship between the capacitance and the physical dimensions was also investigated. The characteristic curves of the open end capacitance were obtained. Also, an empirical formula was established for the open end structures with a thick substrate and narrow gap.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Standardization of provisions for ISDN/PSTN interworking of data terminals (1992)

The provision for the interworking of terminals on an Integrated Services Digital Network (ISDN) with terminals on existing networks is essential to the evolution of ISDN. The author considers the status of standards for the interworking of data terminals using circuit-mode services. The existing network of primary concern is the public switched telephone network (PSTN). The concepts discussed are equally applicable to scenarios where either or both the ISDN or existing network is private. >
A 50-Mbit/s CMOS monolithic optical receiver (1988)

A general-purpose CMOS optical receiver that operates at data rates from 1 to 50 Mb/s has been fabricated in a 1.75- mu m CMOS process. The technology choice resulted in a high level of integration compared with similar bipolar technology receivers. The measured minimum signal current for a 10/sup -9/ bit error rate at 50 Mb/s is 48-nA r.m.s. Automatic gain control gives the receiver an electrical input dynamic range of greater than 60 dB. The outputs are TTL (transistor-transistor logic)-compatible and the chip dissipates less than 500 mW when switching at maximum speed. The die area is 16 mm/sup 2/. A comprehensive noise analysis of the receiver front end provides insight into the design tradeoffs of optical receiver preamplifiers. A wideband precision amplifier used in the linear channel is discussed in detail. A simple method for recovering low-frequency signal information lost in AC coupling is described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A STUDY OF POTENTIAL HISTIDINE DECARBOXYLASE INHIBITORS (1960)

A series of compounds has been examined for ability to inhibit histidine decarboxylase. Histidine analogues having substituents in the imidazole ring showed a wide variation in potency, but these were all much less active than alpha-methyldopa [beta-(3,4-dihydroxyphenyl)-alpha-methylalanine], the most potent known inhibitor of histidine decarboxylase. Some tentative conclusions are drawn regarding the relationship between chemical structure and inhibitory activity.
A heuristic method for aircraft maintenance scheduling under various constraints (2006)

Aircraft maintenance is a very important aspect of aircraft fleet management since it usually accounts for a substantial part of the overall operational costs and sets constraints on the planning of flight operations. Maintenance scheduling underlies typically a large number of constraints. Among them are capacities of maintenance facilities, capacities, and skills of maintenance staff, fleet-specific maintenance rules as well as inter-maintenance flying hours and quarterly flying hour demands. In this paper, we present a novel heuristic method for preventive aircraft maintenance scheduling which has been developed in a joint project of the Institute of Data Analysis and Process Design (IDP) and the Swiss Air Force (SAF). For two fleets we show some results and findings. The algorithms have shown to work very reliable, fast, and with good optimisation results even with strong constraints, e.g. with various manual settings. One of the major benefits is a significant increase in speed to compute a new maintenance/flight plan (now within 5 to 15 minutes; before: 1.5 to 2 days). This allows for a fast reaction on events like thunderstorms (Bernese Oberland, August 2005), tsunamis (Sumatra mission, January/February 2005) etc. Moreover, investigations of “What-If-Analyses” to compare different maintenance strategies can now be carried out efficiently.
Metabolism and growth inhibition of four retinoids in head and neck squamous normal and malignant cells (2001)

Isotretinoin (13-cis-retinoic acid, 13cRA) has proven to be active in chemoprevention of head and neck squamous cell carcinoma (HNSCC). Moreover, both all-trans-retinoic acid (ATRA) and 13cRA induce objective responses in oral premalignant lesions. After binding of retinoids to retinoic acid receptors (RARs and RXRs) dimers are formed that are able to regulate the expression of genes involved in growth and differentiation. We compared the metabolism and level of growth inhibition of 13cRA with that of ATRA, 9cRA and retinol in four HNSCC cell lines and normal oral keratinocyte cultures (OKC). These retinoid compounds are known to bind with different affinities to the retinoic acid receptors. We observed that all retinoids were similar with respect to their capacity to induce growth inhibition. One HNSCC line could be ranked as sensitive, one as moderately sensitive and the remaining two were totally insensitive; OKC were moderately sensitive. The rate at which the cells were able to catabolize the retinoid was similar for all compounds. Retinoid metabolism in HNSCC cells resulted in a profile of metabolites that was unique for each retinoid. These metabolic profiles were different in OKC. Our findings indicate that differences in retinoid receptor selectivity of these retinoids do not influence the level of growth inhibition and rate of metabolism.
An Interview with Jeremiah Pangloss-A Prelude to the Constitutional Debate (1982)

Given the complex nature of nuclear weapons strategy for instituting W.W. II,-a subject (survival) for which most of us display intense feelings that tend to cloud our objectivity-I decided to ask my illustrious friend Dr. Jeremiah Pangloss, to write an introductory piece for this symposium.
Ignorability and Coarse Data (1991)

We present a general statistical model for data coarsening, which includes as special cases rounded, heaped, censored, partially categorized and missing data. Formally, with coarse data, observations are made not in the sample space of the random variable of interest, but rather in its power set. Grouping is a special case in which the degree of coarsening is known and nonstochastic. We establish simple conditions under which the possible stochastic nature of the coarsening mechanism can be ignored when drawing Bayesian and likelihood inferences and thus the data can be validly treated as grouped data. The conditions are that the data be coarsened at random, a generalization of the condition missing at random, and that the parameters of the data and the coarsening process be distinct. Applications of the general model and the ignorability condition are illustrated in a numerical example and described briefly in a variety of special cases.
PriSense: Privacy-Preserving Data Aggregation in People-Centric Urban Sensing Systems (2010)

People-centric urban sensing is a new paradigm gaining popularity. A main obstacle to its widespread deployment and adoption are the privacy concerns of participating individuals. To tackle this open challenge, this paper presents the design and evaluation of PriSense, a novel solution to privacy-preserving data aggregation in people-centric urban sensing systems. PriSense is based on the concept of data slicing and mixing and can support a wide range of statistical additive and non-additive aggregation functions such as Sum, Average, Variance, Count, Max/Min, Median, Histogram, and Percentile with accurate aggregation results. PriSense can support strong user privacy against a tunable threshold number of colluding users and aggregation servers. The efficacy and efficiency of PriSense are confirmed by thorough analytical and simulation results.
Fuzzy-control with a PEARL-based multi-loop controller (2002)

To serve the demand for fuzzy control components in automation systems, manufacturers extend the function block libraries of their multi loop and PLC software by respective function blocks. Other demands are for the openness of PLC software and its adaptation to the IEC 1131 standard which, for the first time, gives recommendations with respect to a task model and task communication. The unique idea of the PEARL PLC is to use an adequate high level real time language for PLC software design and implementation facilitating all mentioned user demands in a totally open form. Definition and verification of fuzzy components are described in the paper and further advantages of the use of high level real time languages in PLCs with respect to safety critical aspects are mentioned.
Development of glaucoma after cataract surgery in dogs: 220 cases (1987–1998) (2000)

Multiple factors appear to contribute to the onset of glaucoma in dogs after cataract surgery. Complications prohibiting IOL placement during cataract surgery may lead to a high risk of glaucoma development.
The original position (2014)

The “original position” is the name Rawls gives to the central formal device in his argument for the two principles of justice within the conception of justice he calls “justice as fairness.” It is perhaps the most well-known part of Rawls’s theory, and not surprisingly, the one over which there has been the most disagreement amongst his readers and commentators. This entry provides an overview of the original position’s place within Rawls’s overall project, discusses its various elements and their justification, and provides a summary of the argument from the original position to the two principles of justice.
In vivo microbubble detection in decompression sickness using a second harmonic resonant bubble detector. (1986)

A resonant bubble detection method based on a second harmonic technique has been used to monitor the femoral vascular system of dogs subjected to rapid decompression. For this study, the detector consisted of two acoustic transducers mounted at right angles to each other that were packaged in a perivascular cuff configuration. This detector responds selectively only to bubbles near resonant size (4.2 mum in diameter); solid particles and large bubbles produce no response. The detector was used to monitor a total of 15 dogs. Eleven dogs were subjected to a series of simulated underwater dives until acute symptoms of decompression sickness occurred; 4 dogs served as controls. In the dived group, either the femoral vein or the femoral artery was monitored. Resonant bubbles were observed in the femoral veins of all 6 dogs monitored at this location. During arterial monitoring, most dogs showed no response, but an occasional weak response was observed in 2 of the dogs. No resonant bubbles were detected in the femoral artery or the femoral vein in any of the controls. The data suggest that this bubble detection method is feasible for in vivo use. Furthermore, 4 mum diameter bubbles are much more prevalent in the veins of dogs suffering from decompression sickness than they are in dog arteries, presumably because they are filtered out effectively by the pulmonary circulation. Modifications of this method are discussed to enhance its accuracy and applicability for quantifying bubble size, location, and number.
Molecular Basis of Skeletal Muscle Regeneration (1996)

Skeletal muscle regeneration is a vital process with important implications for various muscle myopathies and adaptations to physiological overload. Few of the molecular regulatory proteins controlling this process have so far been identified. Several growth factors have defined effects on myogenic precursor cells and appear to also be involved during regeneration. In addition, factors that may be released by cells of the immune system may activate satellite cells during regeneration. Many of these growth factors are associated with signalling cascades which transmit information to the nucleus. The nuclear "receptors" that receive the incoming signals are transcription factors that interact with DNA regulatory sequences in order to modulate gene expression. Of the nuclear factors isolated so far, the immediate-early genes are associated with muscle precursor cell proliferation. This review aims to synthesize the extensive research on myogenic differentiation and relate this to research concerning the molecular regulation of skeletal muscle regeneration.
An empirical Bayes testing procedure for detecting variants in analysis of next generation sequencing data (2013)

Because of the decreasing cost and high digital resolution, next-generation sequencing (NGS) is expected to replace the traditional hybridization-based microarray technology. For genetics study, the first-step analysis of NGS data is often to identify genomic variants among sequenced samples. Several statistical models and tests have been developed for variant calling in NGS study. The existing approaches, however, are based on either conventional Bayesian or frequentist methods, which are unable to address the multiplicity and testing efficiency issues simultaneously. In this paper, we derive an optimal empirical Bayes testing procedure to detect variants for NGS study. We utilize the empirical Bayes technique to exploit the across-site information among many testing sites in NGS data. We prove that our testing procedure is valid and optimal in the sense of rejecting the maximum number of nonnulls while the Bayesian false discovery rate is controlled at a given nominal level. We show by both simulation studies and real data analysis that our testing efficiency can be greatly enhanced over the existing frequentist approaches that fail to pool and utilize information across the multiple testing sites.
