International audience; The description of surface textures in terms of repeated colorimetric and geometric local surface variations is a crucial task for several applications, such as object interpretation or style identification. Recently, methods based on extensions ...

International audience; Solid-state phase transitions in SiC are investigated using diffuse x-ray scattering andMonte Carlo simulations. As an example, the 3C-6H transformation is investigated in detail. The transformation is modeled with a statistical algorithm based o...

The optical Yoneda and Brewster scattering phenomena are studied theoretically based on pertubative solutions of the reduced Rayleigh equations. The Yoneda phenomenon is characterized as an enhancement of the intensity of the diffuse light scattered by a randomly rough ...

International audience; We propose a primal-dual splitting algorithm for solving monotone inclusions involving a mixture of sums, linear compositions, and parallel sums of set-valued and Lipschitzian operators. An important feature of the algorithm is that the Lipschitz...

International audience; We develop a novel Hybrid High-Order method for the simulation of Darcy flows in fractured porous media. The discretization hinges on a mixed formulation in the bulk region and on a primal formulation inside the fracture. Salient features of the ...

Autophagy takes place in seeds, as evidenced by detection of autophagosomes and high expression of ATG genes in Arabidopsis, and the seeds of the atg5 mutant exhibit early browning as well as low and early accumulation of 12S globulin.

On a smooth, compact and oriented manifold without boundary, we give a complete description of the correlation function of a Morse-Smale gradient flow satisfying a certain nonresonance assumption. This is done by analyzing precisely the spectrum of the generator of such...
