Modular periodicity of the Euler numbers and a sequence by Arnold

Sanjay Ramassamy

For any positive integer , the sequence of the Euler up/down numbers reduced modulo was proved to be ultimately periodic by Knuth and Buckholtz. Based on computer simulation…

Fault orientation in damage failure under compression

Véronique Dansereau, Vincent Démery, Estelle Berthier +2

The Mohr-Coulomb criterion is widely used in geosciences to relate the state of stress at failure to the observed orientation of the resulting faults. This relation is based on the…

On the Origin of Diffuse Ionized Gas in the Antennae Galaxy

Peter M. Weilbacher, Ana Monreal-Ibero, Anne Verhamme +14

The "Antennae Galaxy" (NGC 4038/39) is the closest major interacting galaxy system and therefore often taken as merger prototype. We present the first comprehensive integral field…

Diffusion-approximation for a kinetic equation with perturbed velocity redistribution process

Nils Caillerie, Julien Vovelle

We derive the hydrodynamic limit of a kinetic equation with a stochastic, short range perturbation of the velocity operator. Under some mixing hypotheses on the stochastic perturba…

Companions, Causality and Codensity

Damien Pous, Jurriaan Rot

In the context of abstract coinduction in complete lattices, the notion of compatible function makes it possible to introduce enhancements of the coinduction proof principle. The l…

Finite-time universality in nonequilibrium CFT

Krzysztof Gawedzki, Edwin Langmann, Per Moosavi

Recently, remarkably simple exact results were presented about the dynamics of heat transport in the local Luttinger model for nonequilibrium initial states defined by position-dep…

The Hilbert-Galton board

Arvind Ayyer, Sanjay Ramassamy

We introduce the Hilbert-Galton board as a variant of the classical Galton board. Balls fall into a row of bins at a rate depending on the bin, and at random times, each bin gets s…

Information Theory to probe Intrapartum Fetal Heart Rate Dynamics

Carlos Granero-Belinchon, Stéphane Roux, Patrice Abry +3

Intrapartum fetal heart rate (FHR) monitoring constitutes a reference tool in clinical practice to assess the baby health status and to detect fetal acidosis. It is usually analyze…

Ionised gas structure of 100 kpc in an over-dense region of the galaxy group COSMOS-Gr30 at z ~ 0.7

Benoît Epinat, Thierry Contini, Hayley Finley +16

We report the discovery of a 10^4 kpc^2 gaseous structure detected in [OII] in an over-dense region of the COSMOS-Gr30 galaxy group at z~0.725 thanks to deep MUSE Guaranteed Time O…

Turbulence statistics in a 2D vortex condensate

Anna Frishman, Corentin Herbert

Disentangling the evolution of a coherent mean-flow and turbulent fluctuations, interacting through the non-linearity of the Navier-Stokes equations, is a central issue in fluid me…

Phoresis in turbulent flows

Vishwanath Shukla, Romain Volk, Mickaël Bourgoin +1

Phoresis, the drift of particles induced by scalar gradients in a flow, can result in an effective compressibility, bringing together or repelling particles from each other. Here,…

The nature of giant clumps in distant galaxies probed by the anatomy of the Cosmic Snake

Antonio Cava, Daniel Schaerer, Johan Richard +4

Giant stellar clumps are ubiquitous in high-redshift galaxies. They are thought to play an important role in the build-up of galactic bulges and as diagnostics of star formation fe…
