We provide with criteria for a family of sequences operators to share frequently universal vector. These are inspired by the classical Frequent Hypercyclicity Criterion and recent criterion due Grivaux, Matheron Menet where periodic points play central role. As an application, we obtain any operator T in specific class acting on separable Banach space, necessary sufficient condition subset ? co...

Many nephrologists believe that more hemodialysis, whether in the form of longer treatments, more frequent treatments, or both, is better than less. Emerging evidence largely supports this view, with most, although not all studies, showing biochemical, cardiovascular, quality of life, or survival benefits with short daily or slow nocturnal hemodialysis. Much of the focus of studies thus far has...

background: the effect of frequent examinations on the students’ learning has had inconsistent results. this study aimed to assess the effectiveness of fre-quent announced quizzes on the learning of a representative sample of iranian medical students. methods: this experimental study was conducted among 37 fifth semester medical students who had taken the course in protozoology and helmintholog...

Frequent subtree mining has attracted a great deal of interest among the researchers due to its application in a wide variety of domains. Some of the domains include bio informatics, XML processing, computational linguistics, and web usage mining. Despite the advances in frequent subtree mining, mining for the entire frequent subtrees is infeasible due to the combinatorial explosion of the freq...

This study aims to publish a novel similarity metric to increase the speed of comparison operations. Also the new metric is suitable for distance-based operations among strings. Most of the simple calculation methods, such as string length are fast to calculate but doesn’t represent the string correctly. On the other hand the methods like keeping the histogram over all characters in the string ...
