Algebraic tori in the complement of quartic surfaces

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract Let B⊂P3$B\subset \mathbb {P}^3$ be an slc quartic surface. The existence of an embedding Gm3↪P3∖B$\mathbb {G}_m^3\hookrightarrow \mathbb {P}^3\setminus B$ implies that B$B$ has coregularity zero. In this article, we initiate the classification of coregularity zero semi log canonical (slc) quartic surfaces B⊂P3$B\subset \mathbb {P}^3$ for ...

Optimized FOPID‐Controlled Wavelet Neural Network for Sensorless Speed Control of BLDC Motor Drive in Electric Vehicle Power Trains

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
Brushless direct current (BLDC) motors have become the preferred choice for electric vehicle (EV) power trains due to their exceptional performance attributes, including fast dynamic response, high efficiency, durability, low acoustic noise, and minimized electromagnetic interference (EMI), which is critical for applications sensitive to electrical ...

Safety Assessment of Critical Aircraft Systems Under Multisource Uncertainty Based on Evidence Network

open access: yesInternational Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
As civil aircraft components become more autonomous in China, airworthiness certification is facing the problem of insufficient failure data, leading to challenges in terms of uncertainty. Traditional probabilistic models struggle to effectively integrate multisource uncertainties, limiting their application in data‐scarce scenarios.

Good Integers: A Structural Review With Applications to Polynomial Factorization and Algebraic Coding Theory

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
For nonzero coprime integers a and b, a positive integer l is said to be good with respect to a and b if there exists a positive integer k such that l divides ak + bk. Since the early 1990s, the notion of good integers has attracted considerable attention from researchers. This continued interest stems from both their elegant number‐theoretic structure

Some Properties of Hyper Ideals in Hyper Hoop‐Algebras

open access: yesJournal of Applied Mathematics, Volume 2026, Issue 1, 2026.
In this paper, we investigate the structural properties of hyper ideals in hyper hoop‐algebras, a generalization of hoop‐algebras under the framework of hyperstructures. Building upon foundational concepts in hyper group theory and hoop theory, the study introduces definitions for hyper ideals and weak hyper ideals, as well as their absorptive and ...
