• Biophysical numerical model for pulsed field ablation · 2027

  Résumé de la publication : Pulsed-Field Ablation (PFA) is a non-thermal technique for the treatment of cardiac arrhythmias. Predictive numerical models capable of reliably predicting lesion size and shape remain limited. We introduce a biophysics-grounded and inherently anisotropic model for cardiac PFA, derived by homogenization of a…

• Gabor phase retrieval via semidefinite programming · 2026

  Résumé de la publication : We consider the problem of reconstructing a function $f\in L^2(\R)$ given phase-less samples of its Gabor transform, which is defined by $$ \G f(x,\omega) \coloneqq 2^{\frac14} \int_\R f(t) e^{-\pi (t-x)^2} e^{-2\pi i y t}\,\mbox{d}t,\quad (x,y)\in\R^2. $$ More precisely, given sampling positions $\Omega\subseteq…

• A Continuous Approximation Model for the Electric Vehicle Fleet Sizing Problem · 2026

  Résumé de la publication : Establishing the size of an EV fleet is a vital decision for logistics operators. In urban settings, this issue is often dealt with by partitioning the geographical area around a depot into service zones, each served by a single vehicle. Such zones…

• Uncertainty Principle, annihilating pairs and Fourier restriction · 2026

  Résumé de la publication : Let \(G\) be a locally compact abelian group, and let \(\widehat{G}\) denote its dual group, equipped with a Haar measure. A variant of the uncertainty principle states that for any \(S \subset G\) and \(\Sigma \subset \widehat{G}\), there exists a constant \(C(S,…

• On the Three Balls Inequality for Discrete Schrödinger Operators on Certain Periodic Graphs · 2026

  Résumé de la publication : We investigate quantitative unique continuation properties for discrete magnetic Schrödinger operators in certain periodic graphs. This unique continuation property will be quantified through what is known in the literature as a Three Balls Inequality. We are able to extend this inequality to…
