Abstract In these last two lectures, we are interested in models of random (q+1)-regular graphs with N vertices. We study the spectral hole of the adjacency matrix, in the limit where N tends to infinity. We present a result due to Joel Friedman, and …

Abstract Mutual understanding during a conversation is an extremely fast and efficient process : we can process three words per second, often more. However, this observation is not consistent with laboratory experiments showing that processing a single …

Abstract Conversational agents, chatbots and large language models   : from Eliza to ChatGPT and ChatLLAMA. How have very large conversational models been trained ? What are their limits, ethical issues, uses and …

Abstract Animals behave flexibly, seamlessly generalizing knowledge between apparently different scenarios. This is the hallmark of intelligence. To do this, representations and computations in the brain must also be flexible and generalise. In this talk …

Children's Drawings and Geometric Universals: How to Explain Them? Abstract In addition to examining the transcultural diversity of geometric signs, across cultures as well as history, the analysis of children's drawings provides a third route to the …

Abstract Single atom catalysts (SACs) can offer appealing catalytic activity and selectivity for heterogeneous catalysis in general, [1] and for electrocatalysis for energy conversion devices in particular. [ 2] This presentation will describe some …

Abstract Driven by the challenge of anthropogenic climate change, the reconstruction of the Holocene climate has provided historians and archaeologists with new insights into the human past. We are learning that the instability of the Earth system has …

Abstract Poor countries raise relatively few taxes, and this limits their ability to take action to help their populations. How are tax revenues distributed ? How can these countries increase their fiscal …

Abstract The second lecture looked at control structures on a larger scale than the commands (statements ) of the first lecture : the scale of mechanisms for breaking programs down into subroutines, procedures, functions and methods. These linguistic …

Markov fields make it possible to build data models with many variables and a reduced number of parameters, by imposing that the variables have only local interactions. These are defined on a non-directional graph, such as an image grid. A Markov field …

Abstract If love is the founding novel of the West, it expresses its political haunts far more than the assurance of its moral edification. This is the case not only in Albert Cohen's Belle du seigneur , but also, thirty   years earlier, in Denis de …

Abstract In the 17th   century, "   Andromaque   " was used to describe a widow. This meaning, fixed in later texts and in the collective imagination, prevents us from seeing how an author like Racine was able to turn the figure of Andromaque, against the …

Documents and media Download support Abstract In classical antiquity, depictions of children reading are rare, as children were not considered as people in their own right. Indeed, children's reading did not always exist as we know it today. The history …

Abstract Most massive stars live in pairs. Often, since their birth, they have lived close to another star. During their life as a couple, certain events in the life of a star will bring them so close together that they will exchange matter, a phenomenon …

Abstract After a supernova explosion, if the remaining core does not exceed 3 solar masses, it can remain in equilibrium as a neutron star. It is the Pauli pressure of the degenerated neutrons that compensates for gravity. The explosion of the Crab …
