Novelty is a concept of great importance in the writing of a research paper, given that the author has to persuade the audience of the news value of the reported research, which makes it worth publishing. In this paper I…

A new tertiary stibine and bismuthine containing C-heterocyclic selenophene ring have been synthesized. Tris(2-selenophenyl)stibine (1) and tris(2-selenophenyl) bismuthine (2) and characterized by IR, MS, H-1, C-13, COSY, HETCOR NMR spectroscopy. Crystal structures of stibine and bismuthine have been determined. In…

A sustainable energy supply is arguably one of the most pressing problems facing
society today, so there is a huge demand for clean energy technologies. Photocatalytic
water splitting, the disassociation of water into H2 and O2 in the presence of…

Les mécanismes cellulaires et moléculaires qui sous-tendent la mémoire et l’apprentissage chez les mammifères sont incomplètement compris. Le rythme thêta de l’hippocampe constitue l’état « en ligne » de cette structure qui est cruciale pour la mémoire déclarative. Dans la…

Cette thèse interroge l’émergence de ce que j’appelle le problème guerre-communication-public dans le travail de Walter Lippmann (1889-1974), le célèbre journaliste et écrivain, pour ensuite aborder le déploiement ultérieur de ce problème au sein de deux formations contemporaines de pouvoir,…

The ability of building robust semantic space representations of environments is crucial for the development of truly autonomous robots. This task, inherently connected with cognition, is traditionally achieved by training the robot with a supervised learning phase. We argue that…

The exponential increase of subjective, user-generated content since the birth of the Social Web, has led to the necessity of developing automatic text processing systems able to extract, process and present relevant knowledge. In this paper, we tackle the Opinion…

Personalization of web sites has become an important issue in web modeling methods. Many of these methods use similar approaches to specify personalization. However even with similar (personalization) requirements the resulting implementations differ. The consequence is that we cannot reuse…
