Unraveling authoritarian reform decision‐making: A metacognitive–subcognitive model
American Journal of Political Science, EarlyView.Abstract Recent research indicates that state reforms in East and Southeast Asia have been predominantly top‐down and authoritarian‐led. However, this significant observation implicitly relies on important assumptions about authoritarian decision‐making behavior and psychology that remains understudied.

Boundary value problems for integro-differential and singular higher-order differential equations
Open MathematicsWe investigate third-order strongly nonlinear differential equations of the type (Φ(k(t)u″(t)))′=f(t,u(t),u′(t),u″(t)),a.e. on[0,T],\left(\Phi \left(k\left(t){u}^{^{\prime\prime} }\left(t)))^{\prime} =f\left(t,u\left(t),u^{\prime} \left(t),{u}^{^{\prime ...

Upper and Lower Solutions for the FitzHugh– Nagumo Type System of Equations
Моделирование и анализ информационных систем, 2018 We consider a moving front solution of a singularly perturbed FitzHugh–Nagumo type system of equations. The solution contains an internal transition layer, that is, a subdomain where a sharp change in the values of the functions describing the solution ...

Nagumo conditions for systems of second-order differential equations
Journal of Mathematical Analysis and Applications, 1985 The existence of solutions for the boundary value problem \[ (1)\quad x''(t)+f(t,x(t),x'(t))=0,\quad t\in [a,b],\quad x(a)=A,\quad x(b)=B \] where x takes values in a Hilbert space H and f:[a,b]\(\times H\times H\times H\to H\) is a compact mapping, is studied.

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 ...

Existence and uniqueness of radial solutions for elliptic equations with nonlinear gradient terms
Boundary Value ProblemsIn this paper, we discuss the existence and uniqueness of radial solutions of the elliptic equation with nonlinear gradient term { − △ u = f ( | x | , u , x | x | ⋅ ∇ u ) , x ∈ Ω , u | ∂ Ω = 0 , $$ \left \{ \textstyle\begin{array}{l} -\triangle u = f\big(

Positive Invariance Condition for Continuous Dynamical Systems Based on Nagumo Theorem
, 2022 In this paper, we obtain sufficient and necessary conditions of some classical convex sets as positively invariant sets for a continuous dynamical system, namely positive invariance conditions. The approach is based on Nagumo Theorem by deriving the tangent cones of these sets.

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.
