In medical clinical studies, various tests Electronics usually relate to the sample size.This paper proposes several methods to calculate sample sizes for a common test of relative risk ratios in stratified bilateral data.Under the prespecified significant level and power, we derive some explicit formulae and an algorithm of the sample size.The sam
Stygobiont species show common, typical traits derived from their adaptation to subterranean life.Due to the general absence of light in cave environments, the majority of them are eyeless.Although the absence of eyes generally does not allow them to perceive luminous stimuli, some stygobionts still present phototaxis.Previous studies determined th
Background: Osteoclasts are bone-resorbing multinuclear polykaryons essential for bone remodeling, formed through cell fusion of mononuclear macrophage/monocyte lineage precursor cells upon stimulation by the RANK/RANKL system.Recent studies have revealed that a family of tetraspanin proteins, such as CD9, is critically involved in the cell fusion/
This study examined the effect of human resource factors and the moderating role of gender on online teaching intention among course tutors in distance education.A quantitative approach and survey design were adopted for the study.Data were gathered with a self-administered questionnaire from 539-course tutors (teachers on the distance mode) in a u
