In Situ Graph Reasoning and Knowledge Expansion Using Graph‐PRefLexOR

open access: yesAdvanced Intelligent Discovery, Volume 1, Issue 3, December 2025.
Graph‐PRefLexOR is a novel framework that enhances language models with in situ graph reasoning, symbolic abstraction, and recursive refinement. By integrating graph‐based representations into generative tasks, the approach enables interpretable, multistep reasoning.

A Superalgebra Within: Representations of Lightest Standard Model Particles Form a Z25$\mathbb {Z}_2^5$‐Graded Algebra

open access: yesAnnalen 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.

Design and Simulation of an Autotransformer‐Based 18‐Pulse AC‐DC Converter for Enhanced Power Quality in Vector‐Controlled Asynchronous Motor Drives

open access: yesEnergy Science &Engineering, Volume 13, Issue 12, Page 6221-6234, December 2025.
18‐pulse AC/DC converter with T‐connected autotransformer for feeding VCAMD. 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

open access: yes, 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 ...

Acoustic waves interacting with non–locally reacting surfaces in a Lagrangian framework

open access: yesMathematische 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 ...
