We analyze the complexity of the Walk on Spheres algorithm for simulating Brownian Motion in a domain Ω ⊂ R. The algorithm, which was first proposed in the 1950s, produces samples from the hitting probability distribution of the Brownian Motion process on ∂Ω within an error of ε. The algorithm is used as a building block for solving a variety of differential equations, including the Dirichlet P...

introduction: in the current study, we compared the h-indices of web of science (wos), scopus, and gs of the iranian nuclear medicine scientists methods: full time members of two major nuclear medicine research centers of iran with more than 5 year of experience (nuclear medicine research center of mashhad university of medical sciences, and research institute for nuclear medicine of tehran uni...

The paper presents comparative analyses of two publication point systems, The Norwegian and the in-house system from the interdisciplinary Danish Institute of International Studies (DIIS), used as case in the study for publications published 2006, and compares central citation-based indicators with novel publication point indicators (PPIs) that are formalized and exemplified. Two diachronic cit...

Background: Systematic reviews and meta-analysis have significant advantages over conventional reviews in that all available data should be presented. This study aimed to evaluate Iranian systematic reviews and meta-analysis abstracts indexed in WOS and Scopus during 2003-2012 based on PRISMA checklist. Methods: This is an analytical study. We evaluated 46 article abstracts indexed in WOS, 89 a...

BACKGROUND Disciplines differ in their authorship and citation practices, thus discipline-specific h-index norms are desirable. Thus the goal of this study was to examine the relationship between the h-index and academic rank in the field of medical education, and the differences in the h-index between MD's and PhD's in this field. METHODS Due to the absence of a formalized registry of medica...

BACKGROUND Web of Science, Scopus, and Google Scholar are three major sources which provide h-indices for individual researchers. In this study we aimed to compare the h-indices of the academic pediatricians of Mashhad University of Medical Sciences obtained from the above mentioned sources. METHOD Academic pediatrician who had at least 5 ISI indexed articles entered the study. Information re...

This paper studies the correlations between peer review and citation indicators when evaluating research quality in library and information science (LIS). Forty two LIS experts provided judgments on a five-point scale of the quality of research published by 101 scholars; the median rankings resulting from these judgments were then correlated with h-, gand H-index values computed using three dif...
