Labyrinthic granular landscapes

We have numerically studied a model of granular landscape eroded by wind. We show the appearance of labyrinthic patterns when the wind orientation turns by $90^\circ$. The occurence of such structures are discussed. Morever, we introduce the density $n_k$ of ``defects'' as the dynamic parameter governing the landscape evolution. A power law behavior of $n_k$ is found as a function of time. In the case of wind variations, the exponent (drastically) shifts from 2 to 1. The presence of two asymptotic values of $n_k$ implies the irreversibility of the labyrinthic formation process.Comment: 3 pages, 3 figure, RevTe

A Sea Change in the Appellate Process?

Professor David Wexler\u27s essay is certain to engender a sense of fear in appellate judges by its very suggestion that we should undertake such a sweeping reform of the appellate process. But the suggestions should-and will-beget the gnawing feeling that Professor Wexler\u27s analysis of the articles by Professors Nathalie Des Rosiers and Amy Ronner, as well as the questions he poses, require us to explore these ideas further. For those of us who follow the no advisory opinions we might stop there. For thotshee acpapneolnl aotef courts who use a screening process to divert cases to an alternative dispute resolution track at the appellate level, the suggestion of a dialogue may be less intimidating. The probable salutary effects of a therapeutic jurisprudence are too important to ignore the idea. In fact, many jurists, only some intentionally, employ aspect
