GAMM-Mitteilungen, Volume 49, Issue 3, September 2026.Abstract This article investigates the modeling of metallic isotropic porous materials by evaluating and comparing macroscopic and microstructure‐resolved simulation approaches. At the macroscopic level, different variants of the Deshpande‐Fleck (DF) model are implemented to describe the elastoplastic behavior of metallic porous materials.

A Magnetic Resonance Fingerprinting Approach for Simultaneous T1‐ and PRFS‐Based 3D MR‐Thermometry
Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1274-1282, September 2026.ABSTRACT Purpose To evaluate a three dimensional dual echo magnetic resonance fingerprinting sequence for simultaneous proton resonance frequency shift (PRFS) and T1 thermometry during microwave ablation with T1 improving robustness near gas bubble induced susceptibility changes while PRFS provides high precision elsewhere.

Numerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.ABSTRACT In this work, we present an extension of the semi‐discrete Lagrangian‐Eulerian numerical scheme for diffusive‐dispersive conservation law problems, including a jump discontinuous flux function. As in the one‐dimensional scalar hyperbolic case, the no‐flow curves also organize the geometry of the method.

Uniqueness of solutions for fourth-order nonlocal boundary value problems
Boundary Value Problems, 2006 Uniqueness implies uniqueness relationships are examined among solutions of the fourth-order ordinary differential equation, y(4)=f(x,y,y′,y″,y‴), satisfying 5-point, 4-point, and 3-point nonlocal boundary conditions.

Impact of a Stratocumulus Scheme on Clouds and Feedbacks in MIROC7
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Marine stratocumulus (Sc) clouds exert a strong cooling effect on climate by reflecting solar radiation, yet many climate models underestimate their amount and cause uncertainty in equilibrium climate sensitivity (ECS). Herein, we show that incorporating a physically based Sc parameterization into the seventh version of the Model for ...

Nonlocal Boundary Value Problems for q-Difference Equations and Inclusions
International Journal of Differential Equations, 2015 We study boundary value problems for q-difference equations and inclusions with nonlocal and integral boundary conditions which have different quantum numbers. Some new existence and uniqueness results are obtained by using fixed point theorems. Examples

Optical Responses From Zero Optical‐Path‐Length Object
Nanophotonics, Volume 15, Issue 15, 13 August 2026.This work address a fundamental question—what is the ultimately minimal embodiment of optical objects that produce useful optical effects? In fact, such an object does not require nonzero physical and optical‐path‐length volume as opposed to the conventional perception.

On well-posedness of the nonlocal boundary value problem for parabolic difference equations
Discrete Dynamics in Nature and Society, 2004 We consider the nonlocal boundary value problem for difference equations (uk−uk−1)/τ+Auk=φk, 1≤k≤N, Nτ=1, and u0=u[λ/τ]+φ ...
