Review of Memristors for In‐Memory Computing and Spiking Neural Networks

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Memristors uniquely enable energy‐efficient, brain‐inspired computing by acting as both memory and synaptic elements. This review highlights their physical mechanisms, integration in crossbar arrays, and role in spiking neural networks. Key challenges, including variability, relaxation, and stochastic switching, are discussed, alongside emerging ...

Data‐Driven Distributed Safe Control Design for Multi‐Agent Systems

International Journal of Adaptive Control and Signal Processing, Volume 40, Issue 1, Page 137-150, January 2026.
This paper presents a data‐driven control barrier function (CBF) technique for ensuring safe control of multi‐agent systems (MASs) with uncertain linear dynamics. A data‐driven quadratic programming (QP) optimization is first developed for CBF‐based safe control of single‐agent systems using a nonlinear controller. This approach is then extended to the

The legacy of the Cartwright–Littlewood collaboration

Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract Mary L. Cartwright and John E. Littlewood published a short “preliminary survey” in 1945 describing results of their investigation of the forced van der Pol equation ÿ−k(1−y2)ẏ+y=bλkcos(λt+a)$$\begin{equation*} \ddot{y}-k(1-y^2)\dot{y}+y = b \lambda k \cos (\lambda t+a) \end{equation*}$$in which b,λ,k,a$b,\lambda,k,a$ are parameters with k$k$

An Overlapping One‐Step Multiderivative Hybrid Block Method for Solving Second‐Order Initial Value Problems

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.
This paper presents a one‐step multiderivative hybrid block method of Order 12 that incorporates an overlapping strategy, in which intrastep points from the previous block are reused in the current step to enhance accuracy and stability when solving linear and nonlinear initial value problems.

Numerical Study of Fourth‐Order Volterra Partial Integrodifferential Equation With Weakly Singular Kernel via Subdivision Collocation Approach

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
In the present article, an emerging subdivision‐based technique is developed for the numerical solution of linear Volterra partial integrodifferential equations (LVPIDEs) of order four with a weakly singular kernel. To approximate the spatial derivatives, the basis function of the subdivision scheme is used, whereas the time discretization is done with

Solution Dynamics of the Time‐Tempered Fractional Burgers‐Like Equation via an Analytical Tempered Laplace Residual Power Series Method

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This work discusses the time‐tempered fractional Burgers’ equation in the context of Caputo tempered fractional derivative. This equation is crucial for modeling non‐Newtonian fluid flow and long‐memory phenomena that involves a time‐tempering effect. In this paper, we employ a novel approach that combines Laplace transformation and the residual power ...

A Novel Orthogonal TU¯ Chebyshev Polynomial Basis for High‐Accuracy Solution of Fractional Integro‐Differential Equations

Journal of Mathematics, Volume 2026, Issue 1, 2026.
The main question addressed in this study is whether a newly constructed orthogonal basis, which is a combination of first‐ and second‐kind Chebyshev polynomials, can provide a more accurate and efficient numerical method for solving fractional integro‐differential equations.

An Optimized Block Hybrid Spectral Simple Iteration Methods for Solving Nonlinear Evolution Equations

International Journal for Numerical Methods in Engineering, Volume 126, Issue 24, 30 December 2025.
ABSTRACT This study presents a new optimized block hybrid method and spectral simple iteration method (OBHM‐SSIM) for solving nonlinear evolution equations. In this method, we employed a combination of the spectral collocation method in space and the optimized block hybrid method in time, along with a simple iteration scheme to linearize the equations.

Rapid‐Onset Therapeutic Effects of Delta Opioid Receptor Agonists on Depression‐Like Behaviors Induced by Chronic Social Defeat Stress

Neuropsychopharmacology Reports, Volume 45, Issue 4, December 2025.
Delta opioid receptor agonists improved social avoidance, depression, and anxiety‐like symptoms induced by chronic social defeat stress within 14 days of chronic administration. Furthermore, the therapeutic effects were observed earlier than with the existing antidepressant paroxetine (28 days).

Resolution of a persistent pneumothorax by blood patch pleurodesis in a cat (Felis catus) with primary pulmonary lymphoma

Veterinary Record Case Reports, Volume 13, Issue 4, December 2025.
Abstract An 18‐year‐old, spayed, female, domestic shorthair cat was presented to our hospital with acute dyspnoea following an episode of vomiting. Thoracic radiography revealed a severe pneumothorax. Despite multiple thoracocenteses, the pneumothorax persisted. Under general anaesthesia, computed tomography revealed multiple pulmonary masses.
