Are physiological oscillations physiological?
The Journal of Physiology, Volume 604, Issue 9, Page 3672-3693, 1 May 2026.Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Sufficient conditions for nonexistence of gradient blow-up for nonlinear parabolic equations
Electronic Journal of Differential Equations, 2007 In this paper we study the initial-boundary value problems for nonlinear parabolic equations without Bernstein-Nagumo condition. Sufficient conditions guaranteeing the nonexistence of gradient blow-up are formulated.

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 ...

四川大学学报. 自然科学版, 2021 We consider the existence of positive radial solutions to a class of elliptic boundary value problem with gradient term. The existence of positive radial solutions is obtained by using the Leray-Schauder fixed point theorem.

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

Cancer Reports, Volume 9, Issue 1, January 2026.ABSTRACT Background Enfortumab vedotin (EV) has demonstrated clinical benefits as a third‐line monotherapy after chemotherapy and immune checkpoint inhibitors and is currently established, in combination with pembrolizumab, as a first‐line standard therapy for metastatic urothelial carcinoma (mUC). However, dermatologic adverse events (DAEs) are common

Existence of solutions to infinite elastic beam equations with unbounded nonlinearities
Electronic Journal of Differential Equations, 2017 This article concerns the existence of unbounded solutions to fourth-order boundary-value problem on the half-line with two-point boundary conditions. One-sided Nagumo condition plays a special role as it allows an asymmetric unbounded behavior on 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$k$

A Fractional‐Order Discrete‐Time FitzHugh–Nagumo Model With Multiple Time Delays
Computational and Mathematical Methods, Volume 2026, Issue 1, 2026.This paper introduces a novel fractional‐order (FO) discrete‐time FitzHugh–Nagumo model (FHNM) that incorporates multiple time delays to capture the combined effects of memory and transmission latencies inherent in neuronal dynamics. The model is formulated using the Caputo nabla difference operator, providing a rigorous mathematical framework that ...
