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...

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...

Identities , forgeries and disguises Gérard Chollet and

The preservation of your identity could become a major concern. In many situations, you need to claim an identity and this claim needs to be verified somehow. The technology called biometrics may help. But, what if a deliberate impostor claims your identity? Will this forgery be always detected? Biometric identity verification is imperfect. This paper reviews some of the techniques that a delib...
