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.

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.

Advanced Intelligent Systems, Volume 8, Issue 7, July 2026.This work presents a bio‐inspired computing framework for Parkinson's disease analog recognition using electroencephalogram signals. Temporally encoded EEG features stimulate a mycelium‐inspired memristive reservoir, where disease‐related patterns emerge through physical spatiotemporal dynamics.

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 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 ...

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.

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.

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;
