Jost asymptotics for matrix orthogonal polynomials on the real line
, 2011 We obtain matrix-valued Jost asymptotics for block Jacobi matrices under an L1-type condition on Jacobi parameters, and give a necessary and sufficient condition for an analytic matrix-valued function to be the Jost function of a block Jacobi matrix with

Second‐Order Optimality Conditions in a New Lagrangian Formulation for Optimal Control Problems
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT It has been shown recently that optimal control problems with the dynamical constraint given by second‐order system admit a regular Lagrangian formulation. This implies that the optimality conditions can be obtained in a new form based on the variational approach.

Dissolved Organic Matter and Pretreatment Effects on PFAS Removal by Granular Activated Carbon
AWWA Water Science, Volume 8, Issue 3, May/June 2026.ABSTRACT Granular activated carbon (GAC) adsorption is commonly used to remove per‐ and polyfluoroalkyl substances (PFAS) from water. In this study, we evaluated the impact of dissolved organic matter (DOM) concentration and pretreatment on GAC use rates for PFAS removal.

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons
Communications on Pure and Applied Mathematics, Volume 79, Issue 5, Page 1151-1298, May 2026.Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Explicit‐Implicit Material Point Method for Dense Granular Flows With a Novel Regularized µ(I) Model
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 7, Page 3256-3273, May 2026.ABSTRACT The material point method (MPM) is widely employed to simulate granular flows. Although explicit time integration is favored in most current MPM implementations for its simplicity, it cannot rigorously incorporate the incompressible µ(I)‐rheology, an efficient model ubiquitously adopted in other particle‐based numerical methods. While operator‐

Limited contribution by non‐volant small mammals to regeneration in ironstone rocky outcrops
Restoration Ecology, Volume 34, Issue 4, May 2026.Abstract Introduction Animal‐mediated seed dispersal contributes substantially to natural regeneration in degraded areas. However, the role of seed dispersal by non‐volant small mammals (NVSM), mainly marsupials and rodents, in contributing to regeneration remains underexplored, especially in mountaintop, open‐canopy ecosystems.

Polynomial identities for quivers via incidence algebras
Bulletin of the London Mathematical Society, Volume 58, Issue 5, May 2026.Abstract We show that the path algebra of a quiver satisfies the same polynomial identities (PI) of an algebra of matrices, if any. In particular, the algebra of n×n$n\times n$ matrices is PI‐equivalent to the path algebra of the oriented cycle with n$n$ vertices.
