Information limits and Thouless-Anderson-Palmer equations for spiked matrix models with structured noise by Jean Barbier, Francesco Camilli, Yizhou Xu, Marco Mondelli

“…However, existing studies either provide suboptimal algorithms or are limited to a special class of noise ensembles. In this paper, using tools from statistical physics (replica method) and random matrix theory (generalized spherical integrals) we establish the characterization of the information-theoretic limits for a noise matrix drawn from a general trace ensemble. …”

Rapports de force dans l’interaction administrative. Observations sémiotiques sur les rôles actantiels by Clément Commerçon

“…Dans une première partie, nous présenterons une interaction entre un usager et une administration, en partant de l’information préalable donnée à l’échange, que nous considérerons faire partie d’un même ensemble avec sa syntaxe propre. Nous proposerons ensuite un cheminement pour comprendre comment l’articulation entre la circulation d’un objet de valeur, les statuts actantiels et les régimes interactionnels produisent les caractéristiques de la force institutionnelle d’une part, et de la force passionnelle d’autre part.…”

IDENTIFICATION DE RÉGIONS HOMOGÈNES DU POINT DE VUE HYDROLOGIQUE. ÉTUDE DE CAS: LA RÉGION DE LA COURBURE DE L’ARC CARPATIQUE by LILIANA ZAHARIA

“…The conclusions are the following ones: i) the ensemble of the study area is heterogeneous from the point of view of the conditions of formation of the maximum flows; ii) inside this area on we can separate two sub-regions – hilly and mountainous –which heterogeneity is much more reduced, the hilly region being able to even be considered as homogeneous.…”
