Abstract When it comes to building, as with energy, the new doesn't make the old disappear. The extraordinary rise of concrete between 1950 and 2000, far from eradicating other building materials, allowed them to grow : glass of course, steel, wood, but …

Abstract New York, the city of exile for the Surrealists and ethnologist Claude Lévi-Strauss, is the capital of the modern, but also the refuge of the archaic. " Ali Baba's cave ", it provides backdoor exits and an escape from the time of …

Abstract In low- and middle-income countries, there are many small businesses, and few large ones. How can this be explained ? And how do companies in poor countries operate ? Are they as productive ? Do they face specific …

Abstract After an introduction to the entire course and seminar, the first lecture traced the appearance of control structures in the first programming languages (1945-1965) : assembly languages, where control is expressed by unconditional or conditional …

Abstract Challenges are proposed by public services, companies or scientific laboratories, and are based on real-life problems. Participants submit the results of their classification or prediction algorithms, which are then put into competition via the …

The Monte-Carlo method approximates averages by empirical sums of independent samples, which is equivalent to approximating integrals, potentially in very high dimensions. It is used in physics to simulate systems with a large number of degrees of …

Abstract Is love in marriage based on a division between the carnal and the spiritual, which presupposed that a woman could give herself to her husband " without any quivering of the soul " (Georges Duby) ? Despite the efforts of moralists, the Middle …

Abstract After recounting his chance encounter with Carlo Emilio Gadda's La Connaissance de la douleur , Philippe Bordas returns to the work of a great author, little known in France and belatedly known in Italy. For Pasolini, however, Gadda was Dante's …

Documents and media Download support Abstract When interpreting, when reading, what place should be given to details in relation to the overall picture ? We may tend to neglect them in favor of an overall interpretation. Or, on the contrary, we may want …

Catherine Coquery-Vidrovitch : "  Études coloniales, postcoloniales, décoloniales : enjeux et perspectives " Denis Cogneau : "  What is the economic and political assessment of …

Abstract First appearing in the theoretical field, the black hole is now part of the standard astrophysical bestiary. After introducing the concept of the black hole within the framework of the relativistic theory of gravitation - general relativity - we …

Abstract Stars with masses greater than 8 solar masses have a very short life on the main sequence, and then burn helium, followed by carbon, oxygen, etc., until they have a core of iron and silicon. Fusion continues in shells, until the core implodes and …

Abstract What if we built the headquarters of the UN at the center of the earth, equidistant from all states, to make it the very place of the universal ? This seemingly absurd proposal comes not from a science-fiction novel, but from Voltaire's 1761 …

Abstract Flowering plants appeared on the planet over 100 million years ago, and have enjoyed remarkable evolutionary success : they now represent the majority of the living mass on the planet, are at the base of most terrestrial food chains, including …

Abstract Ruelle resonances are characteristics of a dynamical system that describe the fine asymptotics of large-time correlations. It is now well known that this notion is well defined for uniformly hyperbolic smooth systems on compact varieties. In this …

Abstract Recently, Dang and Rivière proved a remarkable identity, which expresses the 0-value of the Poincaré series of any surface of negative curvature as a function of the Euler characteristic. Thus, a Dirichlet series defined from the lengths of …

Abstract Text generation can target different types of languages and take different types of knowledge as input. In this presentation, I will show how neural language models can be adapted to generate text from semantic representation graphs, knowledge …
