This article is a theoretical discussion on the dimensions of learning in play and the dimensions of play in learning, using the playful interaction between children and teachers as a starting point. From an empirical study observations of two situations were chosen, one from a mealtime and one of children’s play, both typical examples of playful interactions between teachers and children. The ...

We determine the function fields of varieties of dimension ≥ 2 defined over the algebraic closure of Fp, modulo purely inseparable extensions, from the quotient by the second term in the lower central series of their pro-` Galois groups.

As a multi-classification problem, classification of moving vehicles has been studied by different statistical methods. These practical applications have various requirements, efficiencies, and performance, such as the size of training sample sets, convergence rate, and inseparable or ambiguous classification issues. With a reduction in its training time, the one-to-many support vector machine ...

A recent Keystone symposium on 'Stem Cell Interactions with their Microenvironmental Niche' was organized by David T. Scadden and Allan C. Spradling. The meeting was held in conjunction with another Keystone symposium, 'Stem Cells and Cancer', at Keystone, Colorado. Among the work that was presented at this meeting, scientists presented data that advances our understanding of the contribution t...

Let L/K be a primitive purely inseparable extension of fields of characteristic p, [L : K] > p, p odd. It is well known that L/K is Hopf Galois for some Hopf algebra H, and it is suspected that L/K is Hopf Galois for numerous choices of H. We construct a family of K-Hopf algebras H for which L is an H-Galois object. For some choices of K we will exhibit an infinite number of such H. We provide ...

Although much has been learned concerning the mechanisms of secretory vesicle formation and fusion at donor and acceptor membrane compartments, relatively little attention has been paid toward understanding how cells maintain a homeostatic membrane balance through vesicular trafficking. In neurons and neuroendocrine cells, release of neurotransmitters, neuropeptides, and hormones occurs through...
