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.

Existence of solutions of a third-order boundary value problem
四川大学学报. 自然科学版, 2018 In this paper,the existence of solutions of a class of fully third order boundary value problem is considered, where f is continuous. Applying the Leray-schauder fixed point theorem, the existence of solutions is obtained under f satisfies an inequality ...

Kolmogorov--Nagumo Mean Frameworks for Conditional Entropy
This study focuses on conditional entropy frameworks based on the Kolmogorov--Nagumo (KN) mean. First, $(η, ψ)$-KN averaging (\texttt{EPKNAVG}), a KN-mean extension of the $η$-averaging (\texttt{EAVG}) framework for $(η, F)$-entropies, is introduced and proven to be equivalent to \texttt{EAVG} under suitable concavification conditions.

Cauchy problem for derivors in finite dimension
Electronic Journal of Differential Equations, 2001 In this paper we study the uniqueness of solutions to ordinary differential equations which fail to satisfy both accretivity condition and the uniqueness condition of Nagumo, Osgood and Kamke.

Pathology International, Volume 76, Issue 5, May 2026.We systematically evaluated preanalytical factors affecting DNA and RNA quality in FFPE tissues using controlled porcine models and clinical specimens. Our findings provide evidence‐based recommendations for optimizing FFPE workflows for comprehensive genomic profiling: use 10% neutral‐buffered formalin with ≤ 24‐h fixation; select blocks < 1 year old;

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

Existence results for singular nonlinear BVPs in the critical regime
Electronic Journal of Qualitative Theory of Differential EquationsWe study the existence of solutions for a class of boundary value problems on the half line, associated to a third order ordinary differential equation of the type $$\left(\Phi(k(t, u'(t))u''(t))\right)'(t)=f \left(t, u(t), u'(t), u''(t) \right), \quad ...
