• A stationarity principle generating effective boundary conditions for second-order homogenization · 2026

  Résumé de la publication : We derive an effective model for a periodic chain of linearly-elastic springs, achieving second-order accuracy in the scale separation parameter $\varepsilon \ll 1$. The chain has finite length and is made up of springs connecting both nearest- and next-nearest-neighbors: it serves as…

• Regularization errors in the resolution of elliptic equations in the presence of discontinuities and interfacial sources · 2026

  Résumé de la publication : In this work we present a systematic analysis of the errors introduced in the solution of elliptic equations by the regularization of discontinuous coefficients, jumps on the primitive variable and interfacial flux sources. By decomposing the system into an outer region and…

• Growth Rate and Energy Dissipation in Wind‐Forced Breaking Waves · 2026

  Résumé de la publication : We investigate the energy growth and dissipation of wind‐forced breaking waves at high wind speed using direct numerical simulations of the coupled air–water Navier–Stokes equations. A turbulent wind boundary layer drives the growth of a pre‐existing narrowband wave field until it breaks,…

• The Acoustic Intentionality of the Montivilliers Nuns. · 2026

  Résumé de la publication : L’article examine la notion d’intentionnalité acoustique dans le contexte des constructions sacrées anciennes en interrogeant la pertinence conceptuelle du terme « réverbération » dans l’étude des édifices historiques – ici, à travers une étude de cas centrée sur la communauté des moniales de Montivilliers…

• Averaged equations for disperse two-phase flow with interfacial properties and their closures for dilute suspension of droplets · 2026

  Résumé de la publication : This article provides a derivation of the averaged equations governing the motion of dispersed two-phase flows with interfacial transport. We begin by revisiting the two-fluid formulation, as well as the distributional form of the interfacial transport equation which holds on the entire…
