Functional Extrapolations to Tame Unbound Anions in Density-Functional Theory Calculations
2019
Standard flavors of density-functional theory (DFT) calculations are known to fail in describing anions, due to large self-interaction errors. The problem may be circumvented using localized basis sets of reduced size, leaving no variational flexibility for the extra electron to delocalize. Alternatively, a recent approach exploiting DFT evaluations of total energies on electronic densities optimized at the Hartree-Fock (HF) level has been reported, showing that the self-interaction-free HF densities are able to lead to an improved description of the additional electron, returning affinities in close agreement with the experiments. Nonetheless, such an approach can fail when the HF densitie…
Multi-resolution anisotropy studies of ultrahigh-energy cosmic rays detected at the Pierre Auger Observatory
2017
We report a multi-resolution search for anisotropies in the arrival directions of cosmic rays detected at the Pierre Auger Observatory with local zenith angles up to $80^\circ$ and energies in excess of 4 EeV ($4 \times 10^{18}$ eV). This search is conducted by measuring the angular power spectrum and performing a needlet wavelet analysis in two independent energy ranges. Both analyses are complementary since the angular power spectrum achieves a better performance in identifying large-scale patterns while the needlet wavelet analysis, considering the parameters used in this work, presents a higher efficiency in detecting smaller-scale anisotropies, potentially providing directional informa…

Les bizutages dans le monde ouvrier en France à l’époque contemporaine
2013
Dans le monde ouvrier, des pratiques informelles de bizutage se reperent, accomplies par des hommes comme par des femmes sur les jeunes jusque vers les annees 1970 environ, pour accompagner leur entree dans les usines. Elles fonctionnent a la fois comme rites de passage, manifestations brutales de domination voire de violence, et blague dont il convient de rire. Mais, parce qu’elles revetent une dimension sexuelle manifeste, elles participent de l’identification des masculinites ouvrieres a la virilite.

Regional currencies and regional monetary zones in Latin America : what prospects ?
2009
9 p.; This paper aims at drawing lessons from Keynes's plan presented at the Bretton Woods conference, in order to help improving current regional monetary agreements in Latin America. Some promoters of the Bank of the South and the New Financial Architecture in Latin America are proposing to implement a regional clearing system designed to allow a multilateral offsetting of the liabilities and assets generated in the reciprocal transactions of member countries in words that the British economist certainly would not have denied. This system would be very different from current regional payments aggreements that maintain an implicit reference to the US dollar as reserve or payment currency.
