This paper studies the implications of interregional redistributive taxation on interregional and interpersonal inequality and on social welfare. We introduce a model of two regions, where individuals are differentiated by their ability and opportunity, the former being determined by heritage and the latter by their residence. Moreover, agents are immobile and respond to interregional transfers...

In normally perfused myocardium, coronary blood flow is greater within the endocardium than in the epicardium because of greater metabolic activity and oxygen requirements. Adequate perfusion is maintained by local autoregulation with greater vasodilation of endocardial arterioles compared with the more constricted epicardial arteriolar bed (l), with alpha-adrenergic tone probably contributing ...

We consider the Robin Hood model of dry friction to study entropy transfer during sliding. For the polished surface (steady state) we study the probability distribution of slips and find an exponential behavior for all the physically relevant asperity interaction-distance thresholds. In addition, we characterize the time evolution of the sample by its spatial fractal dimension and by its entrop...

Thirty years ago, the Robin Hood collision resolution strategy was introduced for open addressing hash tables, and a recurrence equation was found for the distribution of its search cost. Although this recurrence could not be solved analytically, it allowed for numerical computations that, remarkably, suggested that the variance of the search cost approached a value of 1.883 when the table was ...
