The movement of ions across nanopores, or nanoporous membranes, is the elementary process at the heart of most transport issues in biological membranes, or in separation, desalination or osmotic energy technologies. The problem is a priori simple in terms …

The session opens with a tribute to Daniel Roche, who passed away on February 19 2023 . From 1999 to 2005, he held the chair at the Collège de France, Histoire de la France des Lumières, and profoundly renewed the social and cultural history of the modern …

The lecture will juxtapose religious approaches, with an analysis of funeral rites and what is inaccurately referred to as the " ancestor cult ", with a legal study of the ways in which inheritances are …

Abstract Everyone is familiar with the term " biodiversity ". But what does this apparently simple term  actually mean? We hear it over and over again: " biodiversity is in crisis ". Are we on the verge of a sixth extinction, with ourselves as the cause ? …

Humans occupy a place like any other in the tree of life. Every species alive today is endowed with remarkable properties. Nevertheless, humans today occupy a special place on Earth : they have a strong impact on ecosystems, and it is the first time in …

Abstract The presentation of an episode from Osamu Tezuka's immense Phoenix saga, produced over the course of his career, will provide an opportunity to read and see a certain conception of metamorphosis, of the forms taken by life, and of comics as the …

Abstract The conduct of a state's external relations includes the management of transboundary natural resources, including international rivers and groundwater. Promoting respect for the law enables riparian states to seek stability and cooperation in the …

Abstract Disputes may arise over the distribution of water resources or over the increasing scarcity of access to these resources. It is important to prevent tensions and conflicts from arising in these areas. Various diplomatic and judicial mechanisms …

Abstract Preserved at the French Institute of Oriental Archaeology in Cairo, the papyrus presented here contains the hitherto unknown remains of thirty verses by the pre-Socratic philosopher Empedocles of Agrigento ( 5th   century BC), and is …

The analysis of the theogonic components of the Homeric Hymn to Demeter continues with the figure of Demophon, the young child of the rulers of Eleusis whom the goddess undertakes to immortalize. The episode depicts the first consequence of Demeter's …

Abstract School documentation   : its biases and limitations (2) The biggest hurdle facing anyone wishing to work on schooling from papyri is whether or not they are dealing with a school text. This brings us to a review of the criteria for belonging to …

Abstract Recent years have seen a boom in neural network-based techniques for image synthesis. These methods are most often based on the minimization of a function, for which the minimizers are assumed to be the solutions of the synthesis problem. In this …

Abstract The entropy rate of a Markov chain is calculated as a function of its transition matrix. It is shown that the Kullback-Liebler distance (relative entropy) always decreases for two probability distributions evolving along a Markov chain. If the …

Abstract Due to their nanometric porosity and high specific surface area, nanoporous materials are at the heart of fundamental research aimed at studying the role of nanoconfinement and surface forces on thermodynamics and fluid dynamics. Moreover, by …

As Feynman remarked, " Everything that living things do can be understood in terms of the jigglings and wigglings of atoms ". At nanometric scales, fluctuations become predominant. How do they affect transport, and can we take advantage of them for …
