Existence of solutions for higher order $\phi-$Laplacian BVPs on the half-line using a one-sided Nagumo condition with nonordered upper and lower solutions

Cubo, 2023
In this paper, we consider the following $(n+1)$st order bvp on the half line with a $\phi-$Laplacian operator $$ \begin{cases} (\phi(u^{(n)}))'(t)=f(t,u(t),\ldots,u^{(n)}(t)),& a.e., \,t\in [ 0,+\infty ),\\& n\in \mathbb{N}\setminus\{0\}, \\ u^

Cooperative and Non‐Cooperative Solutions in a Dynamic Model of Forest Management

Natural Resource Modeling, Volume 39, Issue 3, August 2026.
ABSTRACT This study develops a deterministic finite‐horizon bioeconomic control model linking forest biomass, biodiversity, cumulative harvesting pressure, and disturbance‐motivated expected biodiversity losses. Biodiversity is modeled as a productive state variable that feeds back into biomass growth, while cumulative harvesting pressure records the ...

Impact of European Association of Urology Combination and Platinum Eligibility on Real‐World Treatment Sequences and Survival in Japanese Patients With Metastatic Urothelial Carcinoma

International Journal of Urology, Volume 33, Issue 5, May 2026.
ABSTRACT Objectives To evaluate the prevalence of European Association of Urology‐defined combination and platinum eligibility at first‐line treatment initiation, and to assess their impact on conventional treatment sequence and overall survival in a real‐world Japanese cohort. Methods We retrospectively analyzed 148 patients with metastatic urothelial

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 ...
