A complex system creates a “whole that is larger than the sum of its parts,” by coordinating many interacting simpler component processes. Yet, each of these processes is difficult to decipher as their visible signatures are only seen in a syntactic background, devoid of the context. Examples of such visible datasets are time-course description of geneexpression abundance levels, neural spike-t...

Double field theory describes a massless subsector of closed string theory with both momentum and winding excitations. The gauge algebra is governed by the Courant bracket in certain subsectors of this double field theory. We construct the associated nonlinear backgroundindependent action that is T-duality invariant and realizes the Courant gauge algebra. The action is the sum of a standard act...

Cet article vise à identifier les déterminants de l'évolution du solde courant algérien l'aide modèle ARDL, sur la période 1980-2020. Les principaux résultats nos analyses montrent que se déduisent en s'appuyant trois caractéristiques essentielles : (1) pression exercée le compte courant, suite volatilité des prix hydrocarbures marché mondial, exacerbe une dépendance pétrolière ; (2) l'inélasti...
