Background: We are living in an era in which different branches of science are growing very rapidly. Therefore, retrieving and summarizing all new valid findings on a specific subject is one of the most important priorities of scientists. The aim of the present article is to categorize different review studies within the health domain based on their approach to retrieving and summarizing ...

Retrieving failed cemented crowns and fixed partial dentures with minimum discomfort to the patient has always been a clinical concern. This article describes a technique which will allow easy and predictable removal of these restorations.

several semantic image search schemes have been recently proposed to retrieve images from the web. however, the query context is regularly ignored in these techniques and hence, many of the returned images are not adequately relevant. in this paper, we make use of context to further confine the outcome of the semantic search engines. for this purpose, we propose a hybrid search engine which uti...

Ultrasound localization microscopy (ULM) is a vascular imaging method that provides 10-fold improvement in resolution compared to ultrasound Doppler imaging. Because typical ULM acquisitions accumulate large numbers of synthetic microbubble (MB) trajectories over hundreds cardiac cycles, transient hemodynamic variations such as pulsatility get averaged out. Here we introduce two independent pro...

Methods of determining, from small-variable asymptotic expansions, the characteristic exponents for variables tending to infinity are analyzed. The following methods considered: diff-log Padé summation, self-similar factor approximation, Borel and Borel–Leroy summation. Several typical problems treated. comparison results shows that all these provide close estimates large-variable exponents. re...
