A Level Set Topology Optimization Theory Based on Hamilton's Principle
International Journal for Numerical Methods in Engineering, Volume 126, Issue 17, 15 September 2025.ABSTRACT In this article, we propose a unified variational framework for deriving the evolution equation of the level set function in topology optimization, departing from conventional Hamilton–Jacobi‐based formulations. The key idea is the introduction of an auxiliary domain, geometrically identical to the physical design domain, occupied by ...

Les trois dimensions de l'espace et les quatre dimensions
de l'espace-temps [PDF]
, 1998 The present work deals with the problem of dimensionality of space, time and space-time, from the points of view of mathematics, physics and epistemology in historical perspective, that show it in its relationships -general as well as particular- with ...

Flow Memory Effect on Open‐Frame Remotely Operated Vehicle Motion
Journal of Field Robotics, Volume 42, Issue 6, Page 2611-2638, September 2025.ABSTRACT The flow memory effect is a kind of viscous force caused by acceleration between continuous phases and underwater vehicles and the development of the boundary layer near the interfacial surface. This paper establishes a 6‐degrees‐of‐freedom unsteady equation of motion describing the flow memory effect on viscous hydrodynamic loads.

Uniqueness of the Canonical Reciprocal Cost
MathematicsWe study a rigidity problem for functions F:R>0→R≥0 that penalize deviation of a positive ratio from equilibrium x=1. Assuming (i) a d’Alembert-type composition law on R>0, and (ii) a single quadratic calibration at the identity (in logarithmic ...

On the Influence of the Fiber Curvature on the Stiffness of Long Fiber Reinforced Composites
International Journal for Numerical Methods in Engineering, Volume 126, Issue 15, 15 August 2025.ABSTRACT The degree of curvature of fiber inclusions in fiber‐reinforced composites impacts the elastic properties of the composite, but numerical studies of this effect are limited by the lack of efficient microstructure generators with fiber curvature control. We propose an extension to the fused Sequential Addition and Migration algorithm (Int.

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect
Advanced Physics Research, Volume 4, Issue 7, July 2025.This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

Le vide matériel ou la matière crée l'espace. [PDF]
, 1998 Nos connaissances actuelles sur le vide font appel à l'ensemble des théories classiques de la physique (requises, par exemple, par l'obtention de vides poussés), aussi bien qu'aux théories relativistes et quantiques et à la cosmologie.

The Southern Journal of Philosophy, Volume 63, Issue 2, Page 211-223, June 2025.Abstract In my article, I propose to analyze the Du Châtelet‐Mairan dispute from the perspective of the modern theory of argumentation, focusing on the study of arguments from authority. I study separately the opinions of Du Châtelet and Mairan on the correct use of the argument from authority (Is the opponent using the argument correctly?
