International Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 224-246, June 2026.ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies

Moments of L$L$‐functions via a relative trace formula
Proceedings of the London Mathematical Society, Volume 132, Issue 4, April 2026.Abstract We prove an asymptotic formula for the second moment of the GL(n)×GL(n−1)$\mathrm{GL}(n)\times \mathrm{GL}(n-1)$ Rankin–Selberg central L$L$‐values L(1/2,Π⊗π)$L(1/2,\Pi \otimes \pi)$, where π$\pi$ is a fixed cuspidal representation of GL(n−1)$\mathrm{GL}(n-1)$ that is tempered and unramified at every place, while Π$\Pi$ varies over a family of

Diophantine tuples and product sets in shifted powers
Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.Abstract Let k⩾2$k\geqslant 2$ and n≠0$n\ne 0$. A Diophantine tuple with property Dk(n)$D_k(n)$ is a set of positive integers A$A$ such that ab+n$ab+n$ is a k$k$th power for all a,b∈A$a,b\in A$ with a≠b$a\ne b$. Such generalizations of classical Diophantine tuples have been studied extensively.

Research on Three‐Dimensional Autonomous Obstacle Avoidance Path Planning Methods for UAVs
Transactions on Emerging Telecommunications Technologies, Volume 37, Issue 2, February 2026.This study presents a three‐dimensional autonomous obstacle‐avoidance path planning method for unmanned aerial vehicles (UAVs) based on a deep reinforcement learning (DRL)‐enhanced Mayfly Algorithm. The traditional Mayfly Algorithm suffers from issues such as random initial population generation and slow convergence.

IET Communications, Volume 20, Issue 1, January/December 2026.This paper proposes a reinforcement learning–based framework for robust modulation classification and resource management in non‐orthogonal multiple access (NOMA) systems. By integrating Q‐learning, deep reinforcement learning, and proximal policy optimisation, the approach enhances spectral efficiency, mitigates interference, and improves ...

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.This paper presents a robust H∞ decentralised and centralised control approach for a microsurgical manipulator using Particle Swarm Optimisation and Gravitational Search Algorithm (PSOGSA). The proposed fixed‐structure Proportional‐Integral‐Derivative (PID)‐based controllers address implementation challenges of conventional high‐order H∞ controllers ...

Families of Multidimensional Periodic Arrays With Large Peak Auto‐ to Cross‐Correlation Ratios
Electronics Letters, Volume 62, Issue 1, January/December 2026.We propose two new families of n‐dimensional periodic arrays for digital video watermarking constructed from shifted versions of a base array obtained by folding a ternary Sidelnikov sequence. The resulting arrays achieve peak autocorrelation of order p^(2l) and low non‐peak auto‐correlation and cross‐correlation of order pl$p^{l}$, for l≥n$l \ge n ...

Optimal Sparse Array Design Against Desired Signal DOA Mismatch for Robust Adaptive Beamforming
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.The performance of the adaptive beamformer is not only related to the array weight but also influenced by the array structure. Different sparse array configurations exhibit varying sensitivities to uncertainties in the signal direction of arrival (DOA).

Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.This paper presents a new design method of a functional observer for a bilinear system class with unknown input and constant time delay present in both state and input vectors. The proposed observer is developed in time and frequency domains. The time domain solution is based on Lyapunov–Krasovskii stability theory, which is transformed on linear ...

Incorporating £‐Complex Intuitionistic Fuzzy Set to Sylow Theorems in Group Theory
Journal of Mathematics, Volume 2026, Issue 1, 2026.The complex intuitionistic fuzzy (CIF) set is an advanced version of the regular intuitionistic fuzzy set. It is made to better show the uncertainty and complexity that arise in real‐life problems. The grading and nongrading degrees in the CIF set are shown by complex‐valued functions that are defined on the unit disc of the complex plane.
