We give an alternative proof of a theorem of Gustafson and Seddighin (1993) following the idea used by Das et al. in an earlier study of antieigenvectors (1998). The result proved here holds for certain classes of normal operators even if the space is infinite dimensional.

Résumé Dans cet article nous allons présenter une méthode pour la détection automatique d’objets artificiels dans des images numériques représentant des milieux naturels. Cette méthode est basée sur la distribution statistique des motifs de texture dans l’image. Cette distribution est calculée en utilisant la loi de Zipf. L’image est divisée en imagettes et la distribution de Zipf est calculée ...

The 30-year history of quasicrystals is one in which, time after time, the conventional scientific view about what is possible has been proven wrong. First, quasicrystals were thought to be mathematically impossible; then, physically impossible; then, impossible unless synthesised in the laboratory under carefully controlled conditions. One by one, these strongly held views have been disproven,...

This paper studies the role of transfers among groups within a country as well as among countries in a two level game of international trade negotiations. We show that in order to realize the intended transfer in the presence of asymmetric information on the states of recipients (and donors), a transfer process uses up additional resources. The difficulty of making transfers renders it less lik...

In this commentary, I explore two questions raised by Angelotta and Appelbaum's study. First, I offer an English legal perspective on the protection of children from their mothers, looking at both civil (family) and criminal law. Second, I discuss the idealization of motherhood that is implied by the prosecution of pregnant women; the denigration of those who fail this ideal; and the way that i...
