Many of the reservations that might attach to the use of meta-analysis generaLly uor example, regarding publication bias) do not apply in the specific context of drug develop-ment. A meta-analysis is, in fact, a highly natural and appropriate way to summarize the results of a drug development

HAL is a multi-disciplinary open access archive for the deposit and dissemination of sci-entific research documents, whether they are pub-lished or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et a ̀ la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d’enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

In this paper, we investigate the security, in the Luby-Rackoff security paradigm, of blockcipher modes of operation allowing to expand a one-block input into a longer t-block output under the control of a secret key K. Such “one-block-to-many ” modes of operation are of frequent use in cryptology

compression standard for continuous-tone still images, both grayscale and color. JPEG’s proposed standard aims to be generic, to support a wide variety of applications for continuous-tone images. To meet the differing needs of many applications, the JPEG standard includes two basic compression methods, each

This work is dedicated to my loving husband Jonny, without whose support, determination and understanding I would never have reached this far. “In physics, you don’t have to go around making trouble for yourself- nature does it for you.”

The high confidence levels are important because they al-low very large databases to be searched exhaustively (one-to-many “identification mode”) without making any false matches, despite so many chances. Biomet-rics lacking this property can only survive one-to-one (“verification

that loopy propagation can also work well for graphs with many small loops. At the same time, our experimental results suggest a cautionary note about loopy propagation, showing that the marginals may exhibit oscillations that have very little correlation with the correct marginals. We presented some

Many popular programs, such as Netscape, use untrusted helper applications to process data from the network. Unfortunately, the unauthenticated network data they interpret could well have been created by an adversary, and the helper applications are usually too complex to be bug-free. This raises
