Upper and Lower Solutions for the FitzHugh– Nagumo Type System of Equations
, 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 ...

QRS Detection in Noisy Electrocardiogram Based on Multi‐Parameter Constrained Stochastic Resonance
IEEJ Transactions on Electrical and Electronic Engineering, Volume 20, Issue 11, Page 1745-1756, November 2025.One major challenge of QRS wave detection is the deleterious impact of inevitable noise in electrocardiogram (ECG) signals, which can deteriorate the detection performance of algorithms. Previous research has shown a nonlinear monostable potential‐based algorithm for enhancing the QRS complex in a noisy environment. Its main mechanism is the stochastic

Psychiatry and Clinical Neurosciences Reports, Volume 4, Issue 3, September 2025.Preferences for gender‐affirming surgery in Japan were shaped by legal and psychological factors, with financial difficulty as the main barrier. Abstract Aim To understand the preferences of individuals with gender incongruence (GI) regarding gender‐affirming surgery (GAS), including gonadectomy.

Development, Growth &Differentiation, Volume 67, Issue 7, Page 406-416, September 2025.ABSTRACT Osteoblast differentiation is essential for skeletal development and homeostasis. Although bone marrow‐derived mesenchymal stem/stromal cells (BM‐MSCs) are commonly used to study osteoblast differentiation in the context of bone homeostasis, their relevance to osteoblast differentiation during human skeletal development remains unclear.

Boundary value problems for singular second order equations [PDF]
, 2018 We investigate strongly nonlinear differential equations of the type (Φ(k(t)u′(t)))′=f(t,u(t),u′(t)),a.e. on [0,T], $$\bigl(\Phi \bigl(k(t) u'(t) \bigr) \bigr)'= f \bigl(t,u(t),u'(t) \bigr), \quad\text{a.e. on } [0,T], $$ where Φ is a strictly increasing

Poincaré–Bendixson theory for certain reaction–diffusion boundary-value problems
, 1994 The paper studies orbits in a function space described by solutions of a system of reaction–diffusion equations in a bounded domain with a boundary condition of homogeneous Robin type. The omega-limit set of a bounded semi-orbit is shown to have a simple

Projecting Multiscale River Flood Changes Across Japan at +2°C and +4°C Climates
Earth's Future, Volume 13, Issue 5, May 2025.Abstract This study addresses computational challenges in high‐resolution, large‐domain, process‐based flood quantile estimation, focusing on Japan's future flood risks at 150 m resolution. Using the Aggregating Grid Event (AGE) method, the Rainfall‐Runoff‐Inundation (RRI) model, and the Peaks‐Over‐Threshold (POT) approach, it incorporates 2,160‐year ...

Stability of N‐front and N‐back solutions in the Barkley model
GAMM-Mitteilungen, Volume 48, Issue 1, March 2025.ABSTRACT In this article, we establish for an intermediate Reynolds number domain the stability of N$$ N $$‐front and N$$ N $$‐back solutions for each N>1$$ N>1 $$ corresponding to traveling waves, in an experimentally validated model for the transition to turbulence in pipe flow proposed in [Barkley et al., Nature 526(7574):550‐553, 2015]. We base our
