It is nearly impossible to separate two interleaved phonebooks by pulling their spines. The very slight force exerted by the outer sheets of the assembly is amplified as the exponential of the square of the number of sheets, meaning that even a small

Faraday-Wave Contact-Line Shear Gradient Induces Streaming and Tracer Self-Organization: From Vortical to Hedgehoglike Patterns
Autor: Pablo Gutiérrez, Leonardo Gordillo, Matías Herrera-Muñoz, Héctor Alarcón, Nicolas Périnet, Nicolás Mujica
Publikováno v: Physical Review Letters. 125
In this Letter, we experimentally demonstrate self-organization of small tracers under the action of longitudinal Faraday waves in a narrow container. We observe a steady current formation dividing the interface in small cells given by Faraday-wave s

The response of a thin layer of granular material to an external pure shear imposed at its base is investigated. The experiments show that, even for noncohesive materials, the resulting deformation of the material is inhomogeneous. Indeed, a novel sm

Self-Amplification of Solid Friction in Interleaved Assemblies
Autor: Thomas Salez, Elie Raphaël, Jean-Francis Bloch, Christophe Poulard, Kari Dalnoki-Veress, Héctor Alarcón, Frédéric Restagno
Publikováno v: Physical Review Letters
Physical Review Letters, American Physical Society, 2016, 116, ⟨10.1103/PhysRevLett.116.015502⟩
It is nearly impossible to separate two interleaved phonebooks when held by their spines. A full understanding of this astonishing demonstration of solid friction in complex assemblies has remained elusive. In this Letter, we report on experiments wi

Characterization of Direct Localization Algorithms for Ultrasound Super-Resolution Imaging in a Multibubble Environment: A Numerical and Experimental Study
Autor: Aline Xavier, Hector Alarcon, David Espindola
Publikováno v: IEEE Access, Vol 10, Pp 49991-49999 (2022)
Localization plays a significant role in the production of ultrasound localization microscopy images. For instance, detecting more microbubbles reduces the time of acquisition, while localizing them more accurately improves the resolution of the imag

International audience; We report on a cellular pattern which spontaneously forms at the surface of a thin layer of a cohesive granular material submitted to in-plane stretching. We present a simple model in which the mechanism responsible of the ins
