Abstract Declines in biodiversity are being observed, and pollinating insects are not spared. Among the environmental pressures on pollinator populations, changes in land use have been identified as a major threat. In Europe, urbanization (expansion and …

Abstract Biodiversity is changing rapidly, but these changes are best known for a few well-studied groups, such as birds and mammals. Insects in general have received much less attention, with the possible exception of honeybees or butterflies. The data …

Abstract This session will be devoted to the deciphering and study of school papyri that are new or misinterpreted by their previous …

Abstract This presentation looks at the environmental history of the Roman province of Egypt, the granary of the Roman Empire. The Nile is the only source of water in this region, its green band easily recognizable on satellite images contrasting with the …

Abstract Throughout the Holocene, natural climatic changes have been a fundamental part of Earth's history, and also of human history. The Romans enjoyed a relatively stable climate, but even so, variability was part of life, and we can study how they …

Abstract The control flow graph is a classic intermediate representation of programs in optimizing compilers for imperative languages. This representation has made it possible to formulate and develop numerous program optimizations, from the simplest to …

Abstract The fourth   lecture introduced the notion of the continuation of a program point in an imperative program, or of a sub-expression in a functional program. This is the sequence of calculations remaining to be performed to reach the end of the …

Abstract How do traditional and new media shape opinions and affect election results ? …

Lecture plan 1. Monasticism and lectures (continued) 1.1. The topos of the illiterate monk: monasteries as a place of unculture or a-culture (continued) 1.2. the monk's duty to know how to read and write 1.3 Monasteries and children: a difficult …

Abstract A causal model describes the distribution of each variable   X as a function of the variables causing   X , and of independent noise (representing other unknown factors influencing   X -   the "   known unknowns   "). A causal model avoids the …

The challenge now is to develop a more efficient algorithm for estimating model parameters. We begin by reviewing the properties of the Kullback-Leibler divergence and the Pinsker inequality that relates it to total variation. An exponential family has a …

Abstract Valentine's Day love poetry is a literary tradition that first found expression at the end of the 14th   century, in England during the reign of Richard   II. Following its transformations right up to Shakespeare and Thomas Hardy, and the "   …

Abstract During their growth and division cycles, proliferating cells must couple their volume growth and macromolecule production to preserve their density, in particular their protein concentration. They must also couple the duration and speed of their …

Abstract In 1789, the French revolutionaries, after declaring that " men are born and remain free and equal in rights ", did not abolish slavery. The Convention did so only in 1794, under pressure from slave revolts and, in particular, the Saint-Domingue …

Abstract Electrochemistry plays a central role in the storage and conversion of renewable energies. It is also at work in a variety of emerging sustainable technologies and devices that have a significant impact on society. Optimizing the performance of …

Abstract This lecture discusses the dynamics of dust particles within a protoplanetary disk, focusing on sedimentation towards the disk midplane and radial drift. These two processes depend on particle size. This size, in turn, is determined by the speed …

Abstract Participatory science can be defined as forms of scientific knowledge production involving - with researchers - citizens. In this seminar, I will review the long history of amateur involvement in science for the study of biodiversity, as well as …
