Annalen der Physik, Volume 537, Issue 12, December 2025.A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.

Regularity results in grand variable exponent Morrey spaces and applications
Electronic Research ArchiveThe boundedness of commutators of Calderón–Zygmund operators in grand variable exponent Morrey spaces is established. The operators and spaces are defined on quasi-metric measure spaces with doubling measure.

ABSTRACT Reducing harmonics in alternating current (AC) input and ripples in direct current (DC) output enhances power quality, achievable through multi‐pulse converters (MPCs). This study presents the design, simulation, and analysis (in MATLAB/Simulink) of an autotransformer‐

Commutation matrices and Commutation tensors
, 2018 The commutation matrix was first introduced in statistics as a transposition matrix by Murnaghan in 1938. In this paper, we first investigate the commutation matrix which is employed to transform a matrix into its transpose. We then extend the concept of the commutation matrix to commutation tensor and use the commutation tensor to achieve the ...

Global Challenges, Volume 9, Issue 12, December 2025.This article introduces a smart solution for the design of a brush DC motor with a winding‐free rotor (DCFR). The proposed model simplifies manufacturing, reduces material costs, and enhances efficiency. Designed for variable speed and solar power applications, the DCFR achieves 91.8% efficiency and a 21% weight reduction compared to conventional ...

Acoustic waves interacting with non–locally reacting surfaces in a Lagrangian framework
Mathematische Nachrichten, Volume 298, Issue 12, Page 3855-3892, December 2025.Abstract The paper deals with a family of evolution problems arising in the physical modeling of small amplitude acoustic phenomena occurring in a fluid, bounded by a surface of extended reaction. They are all derived in a Lagrangian framework. We study well‐posedness of these problems, their mutual relations, and their relations with other evolution ...
