Approche géomorphologique pour déterminer le potentiel de franchissement du trait de côte par les vagues de tempête à partir de l’exemple de la Petite Côte sénégalaise
Published 2023-10-01“…If we focus on the potential for wave overtopping, which depends on the physical characteristics of the coastline under study, notably the height of the coastline, our results from modelling the extreme water level for the 5 events selected show unequal exposure to the risk of coastal flooding and potential overtopping in some places, while in others the coastline is high enough to make overtopping difficult or even impossible.…”

Orbital-selective effect of spin reorientation on the Dirac fermions in a non-charge-ordered kagome ferromagnet Fe3Ge
Published 2024-11-01“…The one with less-dispersive bands (k z ~ 0) containing the $$3{d}_{{z}^{2}}$$ 3 d z 2 orbitals evolves from gapped into nearly gapless, while the other with linear dispersions (k z ~ π) embracing the 3d x z /3d y z components remains intact, suggesting that the effect of spin reorientation on the Dirac fermions has an orbital selectivity. Moreover, we demonstrate that there is no signature of charge order formation in Fe3Ge, contrasting with its sibling compound FeGe, a newly established charge-density-wave kagome magnet.…”

‘Along Footpaths over Snow-Covered Mountains…’ Historical Perspectives on Migration Journeys across the France–Italy Border (1945-1960)
Published 2020-10-01“…The goal of this article is to examine the processes that (both legal and illegal) migration flows across the French-Italian Alps entailed between 1945 and 1960, a period that covers the last big wave of Italian emigration to France. Beyond the analysis of public policies aimed at selecting and managing “desirable migrants”, the study of individual journeys made through a cross-border micro-area – that is, the Aosta and Suse valleys, Beaufortain, Briançonnais and Maurienne – enriches our understanding of mobility phenomena. …”
