L’approche de la performance des firmes par l’identification des facteurs clés de succès (FCS) est très présente dans la littérature en économie et gestion. Cet article propose d’identifier les FCS que les dirigeants des ligues sportives professionnelles françaises jugent les plus importants. L’analyse porte sur trois championnats français : les pr...
Anna Deavere Smith’s embodiment of a series of characters offers a postmodern version of performing hybridity. Fires in the Mirror: Crown Heights, Brooklyn, and Other Identities and Twilight: Los Angeles 1992, created in the early 1990s, brought her fame across the United States most obviously because they provided an artistic answer to the racial ...
La communication a pour objet d'explorer les différents quartiers de Jérusalem dans les pas du canadien Guy Delisle, auteur du reportage graphique « Chroniques de Jérusalem », paru en 2011 et lauréat du Fauve d'or en 2012 (prix du meilleur album du festival de bande dessinée d'Angoulême) et de retranscrire les représentations urbaines de l'œuvre pa...
We investigate cosmological constraints on K-mouflage models of modified gravity. We consider two scenarios: one where the background evolution is free to deviate from $\Lambda$CDM (K-mouflage) and another one which reproduces a $\Lambda$CDM expansion (K-mimic), implementing both of them into the EFTCAMB code. We discuss the main observational sign...

The Galileon model is a tensor-scalar theory of gravity which explains the late acceleration of the Universe expansion with no instabilities and recovers General Relativity in the strong field limit. Most constraints obtained so far on Galileon model parameters from cosmological data were derived for the limited subset of tracker solutions and repo...

It is well known that the standard scalar field mimetic cosmology provides a dark matter-like energy density component. Considering $SU(2)$ gauge symmetry, we study the gauge field extension of the mimetic scenario in spatially flat and curved FLRW spacetimes. Because of the mimetic constraint, the standard Yang-Mills term plays the role of the cos...
Over the last years, radio detection has matured to become a competitive method for the detection of air showers. Arrays of thousands of antennas are now envisioned for the detection of cosmic rays of ultra high energy or neutrinos of astrophysical origin. The data exploitation of such detectors requires to run massive air-shower simulations to eva...
Mixed Damping is a physical effect that occurs when two fluids have interactions with each other but the particles in one fluid are already free-steaming. As such, it is a cross between collisional damping and free-streaming and has never been studied numerically. Mixed damping is particularly relevant in the context of dark matter-neutrino weak in...
