Keynote conference. Abstract Cities are home to a high proportion of the population ; temperature, air pollution and noise levels are generally higher there than elsewhere ; and they are more vulnerable to rising sea levels and flood risks. As a result, …

Abstract To meet future urban challenges, many cities have embarked on a process of " renaturation ", through revegetation programs and actions to increase biodiversity. These actions have many positive impacts on the health and well-being of residents. …

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 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 Philippe Clergeau will present the concept of regenerative urbanism, after recalling the definitions of biodiversity and ecosystems, which are essential to a liveable, sustainable city. Nature-based solutions already permeate architecture, but we …

Abstract Cities are particularly exposed to hydro-climatic hazards, now exacerbated by anthropogenic global warming. As both major sources of greenhouse gas emissions and vulnerable territories, cities are called upon to be drivers of mitigation and …

Abstract This paper examines the future of cities by shifting the focus to the African continent. The aim is to consider African cities as places for exploring new imaginaries and new ways of inhabiting the world. This reflection comes at a crucial time …

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 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 La Chaumière indienne is a short philosophical tale by Bernardin de Saint-Pierre, published in 1791. It depicts the encounter between an English scholar and an Indian outcast, a face-off between the learned culture of the European Enlightenment …

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 …

Abstract First-person thoughts, i.e. thoughts one would express using the pronoun " I ", are reflexive : the thought I would express by saying " I'm hungry " is about myself as the thinker of that thought. In this seminar, I defend an introspectionist …

Abstract A thought, in the sense of Descartes and the Cartesians, is a content of consciousness, whatever it may be. Some contents of consciousness are " representative " and have an object to which they relate. Among these, we distinguish between those …

Abstract The immense diversity of floral characteristics (flower shape, size and color, floral odors) is commonly explained by the shared evolutionary history between plants and pollinators. The many species of pollinator are thought to have played a …

Abstract In the history of life, the first interactions between plants and pollinators were almost concomitant with the appearance of flowering plants, or even preceded it. Through natural selection mechanisms, they led to the evolution of traits that …

Abstract In the past few years, there has been considerable activity around a set of quantum bounds on transport coefficients (viscosity, conductivity) and chaos (Lyapunov exponents), relevant at low temperatures. The interest comes from the fact that …
