With the digitization of media, computers can be employed to help us with the process of classification, both by learning from our behavior to perform the task for us and by exposing new ways for us to think about our information. Given that most of our media comes in the form of electronic text, research in this area focuses on building automatic text classification systems. The standard repre...
BACKGROUND AND PURPOSE The paradox of the reported low prevalence of atrial fibrillation (AF) in blacks compared with whites despite higher stroke rates in the former could be related to limitations in the current methods used to diagnose AF in population-based studies. Hence, this study aimed to use the ethnic distribution of ECG predictors of AF as measures of AF propensity in different ethni...
The most common type of arrhythmia following coronary artery bypass graft (CABG) is atrial fibrillation (AF) with an incidence rate of 20-30%. Pericardial effusion is one of the etiologic factors of atrial fibrillation occurring after CABG. Posterior pericardiotomy (PP) causes the drainage of blood and fluids from the pericardial space into the pleural space leading to a decreased pericardial e...
Swarm is a computational model which extends UNITY in three important ways: (1) UNITY's fixed set of variables is replaced by an unbounded set of tuples which are addressed by content rather than by name; (2) UNITY's static set of statements is replaced by a dynamic set of transactions; and (3) UNITY's static IIcomposition is augmented by dynamic coupling of transactions into synchronic groups....
1878-3317/$ e see front matter Copyright 2011, Ta doi:10.1016/j.jecm.2011.04.004 Atrial fibrillation (AF) is the most common cardiac arrhythmia seen in clinical practice and can induce cardiac dysfunction and strokes. Mechanisms of AF involve a triggering mechanism from thoracic vein and/ or a substrate mechanism in the atria. Studies showed that elimination of ectopic focus from pulmonary vein...
nesar anticline is located in west of country and in north of kermanshah province. pattern of drainage network at each district is under the effect of various factors which has intensive anomaly in nesar anticline in spite of its low area and this in turn reflects different lithology, tectonic effects and slope changes in anticline. the goal of this research is the recognition of influential fa...
BACKGROUND The relationship between pulmonary vein (PV) arrhythmogenicity and its anatomy has been reported. However, that of the superior vena cava (SVC) has not been well discussed. Arrhythmogenic response induced by pacing stimulation at SVC might help with identifying SVC arrhythmogenicity. The purpose of this study was to investigate the relationship between the anatomical dilatation of SV...
