Reconstruction of observed mechanical motions with artificial intelligence tools
New Journal of Physics, 2022 The goal of this paper is to determine the laws of observed trajectories assuming that there is a mechanical system in the background and using these laws to continue the observed motion in a plausible way.

Vacuum Interaction of Crossed Cosmic Strings
Universe, 2021 In this paper, we consider the vacuum energy of a scalar field in the spacetime of two non-parallel cosmic strings. To this end, we obtain metrics for orthogonal straight cosmic strings and for slightly nonparallel strings.

The Problem of Renormalization of Chiral Nuclear Forces
Frontiers in Physics, 2020 Ever since quantum field theory was first applied to the derivation of nuclear forces in the mid-twentieth century, the renormalization of pion exchange with realistic couplings has presented a challenge.

Optimizing Expected Shortfall under an ℓ1 Constraint—An Analytic Approach
Entropy, 2021 Expected Shortfall (ES), the average loss above a high quantile, is the current financial regulatory market risk measure. Its estimation and optimization are highly unstable against sample fluctuations and become impossible above a critical ratio r=N/T ...

Coarse Graining Spin Foam Quantum Gravity—A Review
Frontiers in Physics, 2020 In quantum gravity, we envision renormalization as the key tool for bridging the gap between microscopic models and observable scales. For spin foam quantum gravity, which is defined on a discretization akin to lattice gauge theories, the goal is to ...

A measure of identifying influential community based on the state of critical functionality
Mathematical Biosciences and Engineering, 2020 As an open issue, the measure of community influential is no uniform standard, how to measure the influence of community has attracted extensive attention. This paper proposed a quantitative measure to identify the influence of community.

QUELLE CONCEPTION DE LA RENORMALISATION DANS LE MÉTIER D’ENSEIGNANT ?
Questions Vives, 2023 This article explores the tensions between prescribed norms and teachers’ real activity through the analysis of a training program designed to support their adoption of the Narramus method, recently introduced in Geneva’s primary schools.
