An important characteristic of data transmission systems (DTS’s) is modularity. Since high transfer lines are widely used and constitute an important subclass of DTS’s , in this paper we focus on formal analysis of logic controllers for high volume transfer lines. We propose a systematic approach to model and to verify the space size of the logic controllers using Petri nets. We consider that P...

To the Editor: Kastrati et al recently reported1 significantly less restenosis with lesions randomized to deployment of one stent design (ACS RX Multi-Link, [ML]) than with a related design (Multi-Link RX Duet, [DT]) from the same manufacturer (Guidant). They attributed the difference in restenosis to the difference in strut thickness. Although the two stent designs do differ significantly in s...

This paper presents a theoretical and computational study on the analysis of parameters for distributed temperature sensing in optical fibers, based on spontaneous Raman scattering effect. The parameters studied were the optical power level, the range of frequency modulation and the length of the sensor element, as well as the application of optical frequency domain reflectometry (OFDR). Two di...

It has been found on the basis of experimental data by Redondo and co-workers (Cell. Signal. 2008) that under the conditions of the experiments thrombinstimulated discharge of DTS is negligible compared to that of the acidic stores. There is good reason to believe that SERCA is activated by unbinding calcium ion(s) from the binding site(s) located on the inner (stores-facing) side of the (macro...

In this paper we attempt to define a mathematical model for the formal study of the concept of Digital Territories (DT) and its properties. We describe a simple DT model and employ the first order language of graphs and random graph properties in order to define and study properties of DTs that emerge as soon as the entities (within the DT) population reaches certain threshold points. Our aim i...

In the current work, a series of bithiopheneimide (BTI)-based D-A copolymers were investigated based on the reported PDTSBTI (1) to screen excellent molecules toward organic photovoltaic (OPV) donor materials. It is found that the PCE based on the proposed derivative 4, where the silicon atom is replaced with vinyl and cyano groups on the DTS unit, shows a 70 percent improvement by Scharber dia...

BACKGROUND/AIMS There are several methods for obtaining tissue samples to diagnose malignant biliary strictures during endoscopic retrograde cholangiopancreatography (ERCP). However, each method has only limited sensitivity. This study aimed to evaluate the diagnostic accuracy of a combined triple-tissue sampling (TTS) method (on-site bile aspiration cytology, brush cytology, and forceps biopsy...

We consider numerically the flow of an electrically conducting fluid in a differentially rotating spherical shell, in a dipolar magnetic field. For infinitesimal differential rotation the flow consists of a super-rotating region, concentrated on the particular field line C just touching the outer sphere, in agreement with previous results. Finite differential rotation suppresses this super-rota...

The efficacy of the diazepam loading dose method of treatment of delirium tremens was assessed in comparison with the traditional therapy. The experimental group and the control group comprised 51 and 45 patients respectively. The clinical institute withdrawal assessment for alcohol (CIWA-A) scale was applied to assess the intensity of the symptoms. Diazepam doses in the experimental group osci...

This investigation deals with the intelligent system for parallel fault-tolerant diagnostic tests construction. A modified parallel algorithm for fault-tolerant diagnostic tests construction is proposed. The algorithm is allowed to optimize processing time on tests construction. A matrix model of data and knowledge representation, as well as various kinds of regularities in data and knowledge a...
