Electrodiffusion in cardiac intercalated disc nanostructures alters cell–cell action potential transmission via ephaptic coupling: A model study

The Journal of Physiology, EarlyView.
Abstract figure legend Ephaptic phenomena in a high‐resolution model of the cardiac intercalated disc. Meshed representation of a tortuous intercalated disc that was generated based on electron and super‐resolution microscopy data. Na+ channels (red) and gap junctions (green) are heterogeneously distributed, with additional regions of reduced ion ...

Optimized Spatial Ensemble Approaches for Approximating the Fire Weather Index With Interpolation

Environmetrics, Volume 37, Issue 8, December 2026.
ABSTRACT Wildland fire science and management rely on modeling indicators of wildland fire risk, such as the Fire Weather Index (FWI). Spatial interpolation methods can estimate FWI across a region, but accuracy can vary with observation density and daily spatial dependencies.

Blow-up of solution for the initial boundary value problem of Moore-Gibson-Thompson equation with weighted nonlinear term

四川大学学报. 自然科学版
In this paper， the blow-up of solution for the initial boundary value problem of Moore-Gibson-Thompson equation with weighted nonlinear term on exterior domain in 3D space， i.e.， the complement of some bounded regions in 3D space， is established， where ...

Immersed Boundary Projection Method for Boundaries With Slip Velocities

International Journal for Numerical Methods in Fluids, Volume 98, Issue 12, Page 1266-1292, December 2026.
A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...

The Dirichlet problem for the Brinkman system in exterior domains

Journal of Elliptic and Parabolic Equations
Abstract The Dirichlet problem for the Brinkman system is studied in $$W^{1,q}(\Omega ,{\mathbb {R}}^m) \times L^q_\textrm{loc}(\overline{\Omega })$$

Eigenvalue problems on exterior domains and Dirichlet to Neumann maps

Journal of Computational and Applied Mathematics, 2004
The author considers the eigenvalue problem for the Schrödinger equation with a complex valued potential \(q\) in an exterior domain subject to third kind boundary conditions. It is assumed that \(q\) has a limit \(q(\infty)\) at infinity. The problem is perturbed in a first step by cutting off \(q\) outside of a large ball to obtain a compactly ...

Arbitrary Lagrangian–Eulerian Formulation in a Rotating Frame to Model Friction Spinning

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Friction spinning is a metal forming process that can be used to manufacture various shapes by rotating a metallic workpiece relative to a blunt tool. When used as a hot metal forming process, the relative velocity between workpiece and tool is increased until substantial heat is generated due to friction.

Stochastic Galerkin and Monte Carlo Methods for Parabolic Problems: Numerical Performance of Variational Matrix‐Free Approximations

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Stochastic Galerkin methods offer unexplored potential for the numerical simulation of parabolic problems with random variables, in particular if they are combined with variational discretizations of the space and time variables. Due to the high dimensionality, the solution of the arising algebraic systems do not become feasible without ...

A Two‐Way Coupled Simulation Framework for the Prediction of Fire‐Induced Damage and Smoke Propagation in a Building

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The contribution is concerned with a fully coupled simulation methodology for fire‐induced damage in concrete structures. Fire events in buildings not only generate high temperatures and the spreading of smoke gases but also induce significant structural damages of the concrete structure.
