Objective(s): In heart failure, the heart-to-mediastinum (H/M) ratio of the delayed image and washout rate (WR) are well-known as a powerful cardiac event predictors. H/M ratio quantifies the accumulation rate of MIBG in the myocardium and WR quantifies reduction of meta-iodobenzylguanidine (MIBG) accumulation in the heart from the early planar image to the delayed pla...

The majority of current coreference resolution systems rely on annotated corpora to train classifiers for this task. However, this is possible only for languages for which annotated corpora are available. This paper presents a system that automatically extracts coreference chains from texts in Portuguese without the need for Portuguese corpora manually annotated with coreferential information. ...

We intend to demonstrate the innate problems with existing spreadsheet products and to show how to tackle these issues using a new type of spreadsheet program – Resolver. It addresses the issues head-on and thereby moves the 1980’s “VisiCalc paradigm” on to match the advances in computer languages and user requirements. Continuous display of the spreadsheet grid and the equivalent computer prog...

Position sensorless control has been widely studied for electrical rotor position estimation. However, because of the magnetic periodicity, mechanical multipole electric machine was hardly reported. By increasing dimensions, this article proposes novel topologies named as dual-gap dual-pole composite machines, where can be demodulated from positions two air gaps. The and corresponding theory ar...

The efficiency of the wind power conversions systems can be greatly improved using an appropriate control algorithm. In this work, a sliding mode control for variable speed wind turbine that incorporates a doubly fed induction generator is described. The electrical system incorporates a wound rotor induction machine with back-to-back three phase power converter bridges between its rotor and the...

We have previously shown that complement factor 5a (C5a) plays a role in the pathogenesis of 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis in rats by using the selective, orally active C5a antagonist AcF-[OP(d-Cha)WR]. This study tested the efficacy and potency of a new C5a antagonist, hydrocinnamate (HC)-[OP(d-Cha)WR], which has limited intestinal lumenal metabolism, in this model...

Using the latest stellar evolution models, theoretical stellar spectra, and a compilation of observed emission line strengths from Wolf-Rayet (WR) stars, we construct evolutionary synthesis models for young starbursts. We explicitly distinguish between the various WR subtypes (WN, WC, WO), whose relative frequency is a strong function of metallicity, and we treat O and Of stars separately. We c...

PURPOSE The work rate (WR) corresponding to ventilatory threshold (VT) is an appropriate intensity for regenerative and low-intensity training sessions. During incremental ramp exercise, VO(2) increase lags behind WR increase. Traditionally, a VO(2) time delay (t(d)) of 45 seconds is used to calculate the WR at VT from such tests. Considerable inaccuracies were observed when using this constant...

Doubly fed wound rotor induction machine with vector control is very attractive to the high performance, variable speed drive and generating applications[ 1-31. In variable speed drive application, the so-called slip power recovering scheme is a common practice where the power due to the rotor slip belowlabove synchronous speed is recovered to/supplied from the power source, resulting a high ef...

We study the dynamics of stellar wind bubbles around hydrogen-deficient stars using numerical simulations with timeand ion dependent cooling. We consider two types of hydrogen-deficient stars, massive WR stars, producing Ring Nebulae, and low mass [WR] stars, producing Planetary Nebulae. We show that for the Planetary Nebulae, the different cooling properties of the hydrogen-deficient wind lead...
