During recent years, bibliometric studies have become increasingly important in evaluating individual scientists, institutes, and entire observatories. In astronomy, often librarians are involved in maintaining publication databases and compiling statistics for their institutions. In this paper, we present a look behind the scenes to understand who is interested in bibliometric statistics, whic...

Regulatory approval documents contain valuable information, often not published, to assess the drug–drug interaction (DDI) profile of newly marketed drugs. This analysis aimed to systematically review all drug metabolism, transport, pharmacokinetics, and DDI data available in the new drug applications and biologic license applications approved by the U.S. Food and Drug Administration in 2014, u...

Introduction: Studies have shown that middle school is a decisive time for either promoting or dissuading student interest in the areas of mathematics and science (1). Students who are not engaged in learning these subjects in the critical middle school years often lose interest and motivation by the time they reach high school.

Given independent samples from P and Q, two-sample permutation tests allow one to construct exact level tests when the null hypothesis is P = Q. On the other hand, when comparing or testing particular parameters θ of P and Q, such as their means or medians, permutation tests need not be level α, or even approximately level α in large samples. Under very weak assumptions for comparing estimators...

ardiac resynchronization therapy (CRT) is an effective reatment for heart failure (HF) for patients who still have ignificant symptoms despite optimal medical therapy. any patients with HF have interventricular and intravenricular conduction delays that cause delayed activation of he lateral wall of the left ventricle (LV).
