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

An update on pacemaking in the myometrium
The Journal of Physiology, Volume 604, Issue 9, Page 3661-3671, 1 May 2026.Abstract figure legend The spread of multiple electrical signals (panel A, blue‐to‐red indicates increasing electrical excitability) that are spatiotemporally distinct, yet in‐phase with the excitatory episode, determines action potential shape and form (panel B, as recorded by single cell microelectrodes) and ensures contractile amplitude and duration

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.

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 ...

Existence of three solutions for a higher-order boundary-value problem
Electronic Journal of Differential Equations, 2009 We consider a higher-order multi-point boundary-value problem with a nonlinear boundary condition. Sufficient conditions are obtained for the existence of three solutions.

Error analysis of Crank–Nicolson-FEM for Fitzhugh–Nagumo system with Robin boundary conditions
Partial Differential Equations in Applied MathematicsWe investigate the convergence properties Crank–Nicolson scheme coupled with the finite element approximation of the Fitzhugh–Nagumo system. This model describes the dynamics of excitable media, such as nerve cells, and has applications in various fields, including neuroscience and cardiac modeling.
