Conversions between kinetic and surface energy in periodically forced multiphase turbulence

Jonathan Vahé, Fabien Thiesset

In multiphase flows, kinetic and interfacial energies coexist, and their mutual conversion can potentially influence the overall energy balance. However, in statistically steady fl…

Two-sample test with Wasserstein distance on Gaussian samples based on a log-normal approximation

Johann Clément-Cottuz, Maxime Bérar, Gilles Gasso

In this article, we propose a two-sample test based on the Wasserstein 2-distance between two 1D samples, where the first sample is assumed to be Gaussian based on an approximation…

Frequencies of Patterns in Smooth Sequences Over the Alphabet

Damien Jamet, Irène Marcovici, Léo Poirier +1

We provide an ergodic theory framework to study statistical properties of smooth sequences over the odd alphabet {1,3}. The arithmetic nature of this alphabet yields a partition of…

The effect of grain boundaries on magnetic exchange interactions in iron

Martin Zelený, Martin Heczko, Petr Šesták +3

This work investigates how grain boundaries (GBs) modify magnetic exchange interactions in bcc iron, with particular focus on the effect of phosphorus segregation. Using density-fu…

Population size and centrality effects on NO2 air pollution across and within European cities

Yufei Wei, Rémi Lemoy, Geoffrey Caruso

Understanding how nitrogen dioxide (NO2) varies both within and across cities is essential for assessing urban health inequalities, yet the joint influence of city size and interna…

Modeling (Sub-)millimeter Scattering Properties of Fractal and Consolidated Porous Particles: Applications to Protoplanetary Disks

Gonzalo Vargas, Daniel Guirado, Carlos Carrasco-Gonzalez +5

We perform light-scattering numerical simulations for two dust populations: (i) consolidated porous particles computed with the discrete dipole approximation (ADDA) and (ii) highly…
