Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.Abstract In subwavelength physics, a challenging problem is to characterise the spectral properties of finite systems of subwavelength resonators. In particular, it is important to identify localised modes as well as bandgaps and associated mobility edges.

Review of Summation-by-parts schemes for initial-boundary-value problems
, 2013 High-order finite difference methods are efficient, easy to program, scales well in multiple dimensions and can be modified locally for various reasons (such as shock treatment for example).

European Journal of Heart Failure, Volume 27, Issue 11, Page 2173-2194, November 2025.The diagnosis of atrial cardiomyopathy (AtCM) requires electrical atrial dysfunction, with evidence of either mechanical atrial dysfunction, atrial enlargement, or excessive atrial fibrosis. The diagnostic cut‐points presented are for standard electrocardiogram and echocardiogram studies (see Figure 1 for further detail).

Hierarchical interpolative factorization for elliptic operators: differential equations [PDF]
, 2015 This paper introduces the hierarchical interpolative factorization for elliptic partial differential equations (HIF-DE) in two (2D) and three dimensions (3D).

Space‐Time Boundary Elements on Graded Meshes for 3D Elastodynamics
International Journal for Numerical Methods in Engineering, Volume 126, Issue 20, 30 October 2025.ABSTRACT The solution to the elastodynamic equations in the exterior of a polygonal or polyhedral domain or a screen exhibits singularities at corners and edges. This paper presents a space‐time boundary element method in 3D on algebraically graded meshes to resolve these singularities, based on recently obtained error estimates for the weakly singular

Robust Mammogram Denoising Under Extreme Impulse Noise via FLBMF‐Selective Median‐TV Hybrid Scheme
Engineering Reports, Volume 7, Issue 10, October 2025.(a–g) Original, degraded, and denoised DDSM Mammogram A_0042_1.RIGHT_CC.jpg, S, and P noise densities: 10%, 20%, 40%, 60%, 70%, 80%, and 90%. ABSTRACT Critical for the early detection and precise diagnosis of breast cancer, mammogram imaging risks encountering extreme impulse noise which, in some cases, occurs at levels between 60% and 90%.

Riemann solvers and undercompressive shocks of convex FPU chains
, 2009 We consider FPU-type atomic chains with general convex potentials. The naive continuum limit in the hyperbolic space-time scaling is the p-system of mass and momentum conservation.

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.Abstract The paucity of in situ meso‐scale permeability measurements within subduction zones makes it difficult to fully characterize hydrologic processes and conditions that influence fault zone behavior. In the Hikurangi subduction zone, where large shallow slow slips are observed, there are outstanding questions about the hydrologic influence splay ...
