Gérard de Vaucouleurs (1918–95)

La curieuse destinée des planches anatomiques de Gérard de Lairesse, peintre en Hollande. Lairesse, Bidloo, Cowper

Credit for the discovery of penicillin and its antibacterial effects has been ascribed in varying degrees in the past either to Fleming or to Florey and Chain, all recipients of a Nobel Prize in 1945. Sheehan certainly makes no secret of his support of Fleming, and his facts and arguments are presented to this end. There will be many readers who disagree. The exploitation of the drug in the ear...

l'étude comparative du rêve aurélia de gérard de nerval et la chouette aveugle de hedayat

l’homme a toujours souffert du caractère impeccable du réel qui, imposant des répressions mentales et sociales, interdit la réalisation des souhaits et des désirs. pourtant il semble que rien ne puisse faire d’obstacles à l’esprit humain lorsqu’il prend la voie du rêve, ce phénomène compliqué et surnaturel. mais quelle est la fonction du rêve quand il entre dans le domaine de la littérature? pe...

de Vaucouleurs-Ikeuchi Diagram and Commutation Relations among Phase Space Coordinates

We consider the relations between de Vaucouleurs-Ikeuchi diagram and generalized commutation relations among the coordinates and momenta. All physical objects in the Universe ranging from elementary particles to super cluster of galaxies are confined within the Triangle of the de VaucouleursIkeuchi diagram on the matter density versus scale length plane. These three boundaries are characterized...

Cryptography based on Semigroup Actions ∗ Gérard Maze

A generalization of the original Diffie-Hellman key exchange in (Z/pZ) found a new depth when Miller [27] and Koblitz [16] suggested that such a protocol could be used with the group over an elliptic curve. In this paper, we propose a further vast generalization where abelian semigroups act on finite sets. We define a Diffie-Hellman key exchange in this setting and we illustrate how to build in...
