BACKGROUND T wave alternans (TA) is a repolarisation phenomenon manifesting as a microvolt beat to beat change in the amplitude of the T wave and ST segment. TA has been shown to be a predictor of arrhythmic risk in unselected myocardial infarction populations. TA has not been used to differentiate risk within the ischaemic cardiomyopathy population. METHODS The subjects investigated comprise...

In this paper, we introduce new definitions of L-fuzzy neighborhood systems, L-fuzzy interior operators and L-fuzzy closure operators. Three characterizations of the category L-FTOP of L-fuzzy topological spaces and their L-fuzzy continuous mappings are presented by means of the category L-FNS of L-fuzzy neighborhood spaces and their continuous mappings, the category L-FIS of L-fuzzy interior s...

As a new generation radio telescope, the Allen Telescope Array (ATA) is a prototype for the SKA. Here we describe recently developed design constraints for the ATA digital signal processing chain as a case study for SKA processing. As radio frequency interference (RFI) becomes increasingly problematical for radio astronomy, radio telescopes must support a wide range of RFI mitigation strategies...

Although many studies have analyzed HLA allele frequencies in several ethnic groups in patients with scleroderma (SSc), none has been done in French Caucasian patients and none has evaluated which one of the common amino acid sequences, (67)FLEDR(71), shared by HLA-DRB susceptibility alleles, or (71)TRAELDT(77), shared by HLA-DQB1 susceptibility alleles in SSc, was the most important to develop...

Recently Federici and Scherer [1] proposed an ideal model of an Assistive Technology Assessment (ATA) process that provides reference guidelines for professionals of a multidisciplinary team of assistive technology (AT) service delivery centers to compare, evaluate, and improve their own matching models. The ATA process borrows a user-driven working methodology from the Matching Person and Tech...

To determine the HbO(2) oxygenation level at the microcirculation, we used the hyperbaric chamber. The effects of hyperbaric oxygenation (HBO) were tested on vitality parameters in the brain at various pressures. Microcirculatory hemoglobin oxygen saturation (HbO(2)), cerebral blood flow (CBF) and mitochondrial NADH redox state were assessed in the brain of awake restrained rats using a fiber o...

Yersinia are causative agents in human diseases ranging from gastrointestinal syndromes to Bubonic Plague. There is increasing risk of misuse of infectious agents, such as Yersinia pestis, as weapons of terror as well as instruments of warfare for mass destruction. YopH is an essential virulence factor whose protein-tyrosine phosphatase (PTP) activity is required for Yersinia pathogenicity. Con...

Purpose: to determine the consistency of HVID/WTW measurements on 5 devices, and their correspondence distance from angle (ATA). Methods The relevant information 30 right eyes was obtained volunteers. A prospective study conducted using Wavelight Topolayzer Vario (Alcon), IOL Master 700 (Zeiss), OA2000 (Tomey), AS-OCT Casia 2 Zeiss Atlas 9000 (Carl Zeiss) instruments. Agreement between measurem...
