Gain-controlled directional scattering in core-shell nanoparticles mediated by magnetic toroidal dipoles

Tiago J. Arruda

Toroidal dipole moments arise from poloidal current distributions and form a distinct class of electromagnetic excitations with unique near-field characteristics. Using Lorenz-Mie…

Introduction to Higher Order Classical Dynamics: Pais-Uhlenbeck Model and Coupled Oscillators

Cássius Anderson Miquele de Melo, Ivan Francisco de Souza

Most of the laws of Nature involve derivatives up to the second order. Ostrogradski was the first to seek a formulation of the equations of higher-order derivatives. He extended Ha…

An overview of the fractional-order gradient descent method and its applications

Higor V. M. Ferreira, Camila A. Tavares, Nelson H. T. Lemes +1

Recent studies have shown that fractional calculus is an effective alternative mathematical tool in various scientific fields. However, some investigations indicate that results es…

Tilings of a bounded region of the plane by maximal one-dimensional tiles

Eduardo J. Aguilar, Valmir C. Barbosa, Raul Donangelo +2

We study the tiling of a two-dimensional region of the plane by -cell one-dimensional tiles, or -mers. Unlike previous studies, which typically allowed for one single value o…

Towards mono-energetic virtual beam cross-section measurements: A feasibility study of -Ar interaction analysis with DUNE-PRISM

DUNE Collaboration, S. Abbaslu, A. Abed Abud +1321

Neutrino-nucleus cross-section measurements are critical for future neutrino oscillation analyses. However, our models to describe them require further refinement, and a deeper und…

Brans-Dicke-like field for co-varying and : observational constraints

J. Bezerra-Sobrinho, R. R. Cuzinatto, L. G. Medeiros +1

Ref. [Symmetry 15 (2023) 709] introduced a Brans-Dicke-like framework wherein the scalar field is composed of both and which, for this reason, co-vary according to $c^{…
