The alignment of the left-right (LR) body axis relative to the anteroposterior (AP) and dorsoventral (DV) axes is central to the organization of the vertebrate body plan and is controlled by the node/organizer. Somitogenesis plays a key role in embryo morphogenesis as a principal component of AP elongation. How morphogenesis is coupled to axis specification is not well understood. We demonstrat...

Munn [9] has shown that for a semigroup S satisfying the minimal condition on principal ideals, there is a natural one-to-one correspondence between irreducible representations of S and irreducible representations vanishing at zero of its 0-simple (or simple) principal factors; for the case of S finite, see Ponizovskii [11]. On the other hand, Clifford, [3] and [4], has obtained all representat...

Abstract Introduction Sleep valuation is the relative worth placed on sleep. Individual differences in sleep relate to age, gender, depression, and overall health. The factor structure of how subfactors health outcomes remain unclear. This study investigated latent factors Methods Data were collected from 125 adults, primarily college students (59% female, mean age 21, 87% white), who completed...

Purpose Measuring internal response of online learning is seen as fundamental to absorptive capacity which stimulates knowledge assimilation. However, the evaluation practice and research validated instruments that could effectively measure behavior limited. Thus, in this study, a new instrument was designed based on literature determine structural variables exist behavior. Design/methodology/a...
