Effect of confinement on dense packings of rigid frictionless spheres and polyhedra
Jean-François Camenen, Yannick Descantes, Patrick Richard
We study numerically the influence of confinement on the solid fraction and on the structure of three-dimensional random close packed (RCP) granular materials subject to gravity. T…
Linear Algebra over Z_p[[u]] and related rings
Xavier Caruso, David Lubicz
Let R be a complete discrete valuation ring, S=R[[u]] and n a positive integer. The aim of this paper is to explain how to compute efficiently usual operations such as sum and inte…
Experimental Investigation of Plastic Deformations Before Granular Avalanche
Axelle Amon, Roman Bertoni, Jérôme Crassous
We present an experimental study of the deformation inside a granular material that is progressively tilted. We investigate the deformation before the avalanche with a spatially re…
Seismic diagnostics for transport of angular momentum in stars 1. Rotational splittings from the PMS to the RGB
J. P. Marques, M. J. Goupil, Y. Lebreton +12
Rotational splittings are currently measured for several main sequence stars and a large number of red giants with the space mission Kepler. This will provide stringent constraints…
Complexe de poids des variétés algébriques réelles avec action
Fabien Priziac
Using the functoriality of C. McCrory and A. Parusiński's weight complex -which induces an analog of the weight filtration for complex algebraic varieties on the Borel-Moore homolo…
An explicit expression of the Luroth invariant
Romain Basson, Reynald Lercier, Christophe Ritzenthaler +1
In this short note, we give an algorithm to get an explicit expression of the Luroth invariant in terms of the Dixmier-Ohno invariants. We also get the explicit factorized expressi…
Reachability of Communicating Timed Processes
Lorenzo Clemente, Frédéric Herbreteau, Amélie Stainer +1
We study the reachability problem for communicating timed processes, both in discrete and dense time. Our model comprises automata with local timing constraints communicating over…
The Hofer question on intermediate symplectic capacities
Alvaro Pelayo, San Vu Ngoc
Roughly twenty five years ago Hofer asked: can the cylinder B^2(1) \times \mathbb{R}^{2(n-1)} be symplectically embedded into B^{2(n-1)}(R) \times \mathbb{R}^2 for some R>0? We sho…
Spectral theory of piecewise continuous functions of self-adjoint operators
Alexander Pushnitski, Dmitri Yafaev
Let , be a pair of self-adjoint operators for which the standard assumptions of the smooth version of scattering theory hold true. We give an explicit description of the a…
Hybrid models of the cell cycle molecular machinery
Vincent Noel, Dima Grigoriev, Sergei Vakulenko +1
Piecewise smooth hybrid systems, involving continuous and discrete variables, are suitable models for describing the multiscale regulatory machinery of the biological cells. In hyb…
Boundary regularity of rotating vortex patches
Taoufik Hmidi, Joan Mateu, Joan Verdera
We show that the boundary of a rotating vortex patch (or V-state, in the terminology of Deem and Zabusky) is of class C^infinity provided the patch is close enough to the bifurcati…
Seismic signature of envelope penetrative convection: the CoRoT star HD 52265
Yveline Lebreton, MarieJo Goupil
Aims: We aim at characterizing the inward transition from convective to radiative energy transport at the base of the convective envelope of the solar-like oscillator HD 52265 rece…
The Tate conjecture for K3 surfaces over finite fields
François Charles
Artin's conjecture states that supersingular K3 surfaces over finite fields have Picard number 22. In this paper, we prove Artin's conjecture over fields of characteristic p>3. Thi…
Silo collapse under granular discharge
G. Gutiérrez, C. Colonnello, P. Boltenhagen +4
We investigate, at a laboratory scale, the collapse of cylindrical shells of radius and thickness induced by a granular discharge. We measure the critical filling height fo…
Triangulable $\CO_F$-analytic -modules of rank 2
Lionel Fourquaux, Bingyong Xie
The theory of -modules is a generalization of Fontaine's theory of -modules, which classifies -representations on $\CO_F$-modules and -vector spaces for any…
Coupling techniques for nonlinear hyperbolic equations. IV. Multi-component coupling and multidimensional well-balanced schemes
Benjamin Boutin, Frédéric Coquel, Philippe G. LeFloch
This series of papers is devoted to the formulation and the approximation of coupling problems for nonlinear hyperbolic equations. The coupling across an interface in the physical…
Orbital currents, anapoles, and magnetic quadrupoles in CuO
S. Di Matteo, M. R. Norman
We show that orbital currents in a CuO2 plane, if present, should be described by two independent parity and time-reversal odd order parameters, a toroidal dipole (anapole) and a m…
Reduction of dynamical biochemical reaction networks in computational biology
Ovidiu Radulescu, Alexander N. Gorban, Andrei Zinovyev +1
Biochemical networks are used in computational biology, to model the static and dynamical details of systems involved in cell signaling, metabolism, and regulation of gene expressi…
A First Search for coincident Gravitational Waves and High Energy Neutrinos using LIGO, Virgo and ANTARES data from 2007
The ANTARES Collaboration, the LIGO Scientific Collaboration, the Virgo Collaboration +959
We present the results of the first search for gravitational wave bursts associated with high energy neutrinos. Together, these messengers could reveal new, hidden sources that are…
Search for gravitational waves associated with gamma-ray bursts during LIGO science run 6 and Virgo science runs 2 and 3
The LIGO Scientific Collaboration, Virgo Collaboration, J. Abadie +807
We present the results of a search for gravitational waves associated with 154 gamma-ray bursts (GRBs) that were detected by satellite-based gamma-ray experiments in 2009-2010, dur…
Cubic fourfolds containing a plane and a quintic del Pezzo surface
Asher Auel, Marcello Bernardara, Michele Bolognesi +1
We isolate a class of smooth rational cubic fourfolds X containing a plane whose associated quadric surface bundle does not have a rational section. This is equivalent to the nontr…
Conservative Subgroup Separability For Surfaces With Boundary
Mark D. Baker, Daryl Cooper
If F is a surface with boundary, then a finitely generated subgroup without peripheral elements of G = π_1(F) can be separated from finitely many other elements of G by a finite in…

Massimo Campanino, Dimitri Petritis
Simple random walks on a partially directed version of are considered. More precisely, vertical edges between neighbouring vertices of can be traverse…

J. Aasi, J. Abadie, B. P. Abbott +798
Between 2007 and 2010 Virgo collected data in coincidence with the LIGO and GEO gravitational-wave (GW) detectors. These data have been searched for GWs emitted by cataclysmic phen…
