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 …

In elite families, daughters were sometimes vowed to the local deity : the best known are the nun-nadîtum , particularly those of the god Šamaš in Sippar. Princesses could also become priestesses, like those dedicated to Sin in Ur or Šamaš in …

Abstract Population genetics is the discipline of tracing the evolutionary history of populations and species by analyzing their DNA sequences. This alternative to archaeology enables us to better understand the movements of past populations, their …

The sequencing and comparison of DNA sequences has made it possible to discover important phenomena in living organisms that were previously hidden from our senses. Reconstruction of kinship links between species, biogeography, evolution of character …

Abstract The Organization for the Development of the River Senegal (OMVS) is unique in many respects. The organization has enabled its member states to pool their financial and human resources to invest in the construction of major development …

Abstract The construction of dams and other hydraulic structures can be a source of tension and dispute between riparian states. International law attempts to dispel them through confidence-building measures, based in particular on the communication of …

Abstract The public will be asked to consider the functions of a wooden tablet containing a contract written in Greek on one side, dating from the 7th   century AD. The reverse, containing a text in Coptic, may provide the …

The Hymn " Homeric " to Demeter has been preserved as part of a collection of thirty-three hymnal pieces in honor of a whole series of divinities, whose hexametric form has associated them with Homer's name. Both the date and length of these poems vary. …

Abstract The centrality of schools The centrality of the school explains why the State and the Church were particularly interested in it during the period we're looking at. The former paid increasing attention to teaching, and for this reason was the …

Abstract Despite the rapid evolution in the development and deployment of machine learning methods in almost all areas of society, our theoretical understanding of the mechanisms behind this success remains rather limited. As discussed several times in …

Abstract The Shannon-MacMillan-Breiman theorem proves the asymptotic equipartition property in typical sets, as soon as the process is ergodic. The notion of ergodicity and Birkhoff's theorem are introduced, but not proved. The main argument of the proof …

Abstract Liquids are usually described within classical physics, whereas solids require the tools of quantum mechanics. I will show how in nanoscale systems this distinction no longer holds. At these scales, liquid flows may in fact exhibit quantum …
