Periodic Third-Order Problems with a Parameter [PDF]

, 2021
This work concerns with the solvability of third-order periodic fully problems with a weighted parameter, where the nonlinearity must verify only a local monotone condition and no periodic, coercivity or super or sublinearity restrictions are assumed, as

Pattern Formation in Non‐Equilibrium Architected Materials

Advanced Materials Technologies, Volume 11, Issue 10, 22 May 2026.
This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.

Adrenocortical Carcinoma in Peutz–Jeghers Syndrome With a Rare STK11 Pathogenic Germline Variant: A Case Report

Cancer Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background Peutz–Jeghers syndrome (PJS) is an inherited, autosomal‐dominant condition, featuring STK11 germline mutations, characterized by hamartomatous gastrointestinal polyps and increased cancer risk. The most commonly associated malignancies are gastrointestinal, pancreatic, and breast cancers.

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

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 ...

A Hartman-Nagumo type condition for a class of contractible domains [PDF]

, 2013
We generalize an existence result on second order systems with a nonlinear term satisfying the so-called Hartman-Nagumo condition. The generalization is based on the use of Gauss second fundamental form and continuation techniques.Fil: Amster, Pablo ...

Bifurcation analysis of the travelling waveform of FitzHugh-Nagumo nerve conduction model equation

, 1997
The FitzHugh-Nagumo model for travelling wave type neuron excitation is studied in detail. Carrying out a linear stability analysis near the equilibrium point, we bring out various interesting bifurcations which the system admits when a specific Z2 ...

Boundary value problems associated with singular strongly nonlinear equations with functional terms [PDF]

, 2021
We study boundary value problems associated with singular, strongly nonlinear differential equations with functional terms of type (φ (k (t) x ′ (t))) ′ + f (t, G x (t)) ρ (t, x ′ (t)) = 0, on a compact interval [a, b].

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

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.
