As the improvement of computing power, texting mining becomes more focused than before. In order to realize the literature productivity of such territory, we analyze the literatures on SSCI database with subjects as “Text Mining”. Applied the methodology of bibliometrics, we found several outcomes in this research. First, the distribution of frequency indexes of author’s productivity fulfills L...

Introduction: SRAS-Cov-2, First found on December 2019 in Wuhan China has turned into a worldwide health care problem. The changes genetic drift, recombination, natural selection, and other mutations originated variants of medical concern because the its transmissibility, pathogenesis, or capacity to avoid immune system. This is mainly structural proteins as spike protein.
 Objective: Desc...

In this article we investigate two-level split-plot designs where the sub-plots consist of only two mirror image trials. Assuming third and higher order interactions negligible, we show that these designs divide the estimated effects into two orthogonal sub-spaces, separating sub-plot main effects and sub-plot by whole-plot interactions from the rest. Further we show how to construct split-plot...

A new construction of combings is used to distinguish between several previously indistinguishable classes of groups associated to the theory of automatic groups and non-positive curvature in group theory. We construct synchronously bounded combings for a class of groups that are neither bicombable nor automatic. The linguistic complexity of these combings is analysed: in many cases the languag...

BACKGROUND Although atrial function has prognostic significance in many cardiovascular conditions, changes during exercise have not previously been assessed. The aim of this study was to evaluate left atrial (LA) and right atrial (RA) volume and function during incremental exercise, both in normal individuals, healthy athletes, and in patients with chronic thromboembolic pulmonary hypertension ...

OBJECTIVE To investigate the relationship between science production and the indexation level of low- and middle-income countries (LAMIC) journals in international databases. METHOD Indicators of productivity in research were based on the number of articles produced over the 1994-2004 period. A survey in both Medline and ISI/Thomson was conducted to identify journals according to their countr...
