Commutativity theorems for rings with constraints on commutators [PDF]
International Journal of Mathematics and Mathematical Sciences, 1991 In this paper, we generalize some well‐known commutativity theorems for associative rings as follows: Let n > 1, m, s, and t be fixed non‐negative integers such that s ≠ m − 1, or t ≠ n − 1, and let R be a ring with unity 1 satisfying the polynomial identity ys[xn, y] = [x, ym]xt for all y ∈ R.

Development of a preclinical testing platform for clinically relevant therapy for Dravet syndrome
Epilepsia, EarlyView.Abstract Objective Patients with drug‐resistant epilepsy, including Dravet syndrome, are frequently prescribed multiple antiseizure medications. Nevertheless, people with Dravet syndrome often have inadequate seizure control, and there is an ongoing unmet clinical need to identify novel therapeutics.

Química Nova, 2001 An important component for the automation of flow injection analysis (FIA) systems is the sample injection valve. A simple and inexpensive commutator with 16 pinch valves (8 normally open and 8 closed) was developed and configured as a multichannel ...

Analytic Philosophy, EarlyView.ABSTRACT Laws play some role in explanations: at the very least, they somehow connect what is explained, or the explanandum, to what explains, or the explanans. Thus, thermodynamical laws connect the match's being struck and its lightning, so that the former causes the latter; and laws about set formation connect Socrates' existence with {Socrates}'s ...

Where Mathematical Symbols Come From
Topics in Cognitive Science, EarlyView.Abstract There is a sense in which the symbols used in mathematical expressions and formulas are arbitrary. After all, arithmetic would be no different if we would replace the symbols ‘+$+$’ or ‘8’ by different symbols. Nevertheless, the shape of many mathematical symbols is in fact well motivated in practice.

Compactifications of strata of differentials
Bulletin of the London Mathematical Society, EarlyView.Abstract In this informal expository note, we quickly introduce and survey compactifications of strata of holomorphic 1‐forms on Riemann surfaces, that is, spaces of translation surfaces. In the last decade, several of these have been constructed, studied, and successfully applied to problems.

Bounded cohomology of groups acting on trees with almost prescribed local actions
Bulletin of the London Mathematical Society, EarlyView.Abstract We prove the vanishing of bounded cohomology of the groups acting on trees with almost prescribed local actions G(F,F′)$G(F, F^{\prime })$, where F
