Réponse des verres dosimètres aux fortes irradiations gamma

Symétrie des interactions fortes

We review recent developments in strong interaction symmetries. We have tried to emphasize a simple approach starting from very well known facts such as charge independance and isotopic spin. We then present unitary symmetry after a short introduction to the language of Lie Algebras. The experimental data, on masses, multiplets, scattering cross sections are confronted with the theory. We brief...

Méthodes numériques pour l'étude de la dynamique des phénomènes critiques : application aux verres de spins

Réponse à des tests de compréhension

This paper presents an adaptation of an existing question answering system for a machine reading task. The proposed method for selecting correct answers relies on textual entailment recognition between hypotheses and texts. The specificities of this method are the generation of hypotheses by parse tree modification and the evaluation of several distance criteria, adapted to take into account te...

Des miasmes aux virus

relationships, whether in the operating theatre or among hospital administrative staff, are often explicit and rarely absent; while even the most innocuous illustrations of waiting rooms, hospital wards, and roof gardens reveal the therapeutic gap that separated the rich from the poor. Nor can the broader context be easily ignored: developments in medical technology, operating techniques, and d...

Des séquences aux tendances

RÉSUMÉ. Les données temporelles peuvent être traitées de nombreuses façons afin d’en extraire des connaissances. La découverte de motifs séquentiels met en évidence des sous-séquences fréquentes contenues dans des séquences d’enregistrements annotés temporellement. L’analyse des accès à un site web permet par exemple de découvrir que “5% des utilisateurs accèdent à la page register.php puis à l...
