Solvability of invariant systems of differential equations on H2$\mathbb {H}^2$ and beyond
Mathematische Nachrichten, Volume 299, Issue 2, Page 456-479, February 2026.Abstract We show how the Fourier transform for distributional sections of vector bundles over symmetric spaces of non‐compact type G/K$G/K$ can be used for questions of solvability of systems of invariant differential equations in analogy to Hörmander's proof of the Ehrenpreis–Malgrange theorem.

Bidiagonal Decompositions and Accurate Computations for the Ballot Table and the Fibonacci Matrix
Numerical Linear Algebra with Applications, Volume 33, Issue 1, February 2026.ABSTRACT Riordan arrays include many important examples of matrices. Here we consider the ballot table and the Fibonacci matrix. For finite truncations of these Riordan arrays, we obtain bidiagonal decompositions. Using them, algorithms to solve key linear algebra problems for ballot tables and Fibonacci matrices with high relative accuracy are derived.

Definition and Computation of Tensor‐Based Generalized Function Composition
Numerical Linear Algebra with Applications, Volume 33, Issue 1, February 2026.ABSTRACT Functions are fundamental to mathematics as they offer a structured and analytical framework to express relations between variables. While scalar and matrix‐based functions are well‐established, higher‐order tensor‐based functions have not been as extensively explored.

Exploration of the Predictive Validity of Middle School Math Screeners
Psychology in the Schools, Volume 63, Issue 2, Page 423-432, February 2026.ABSTRACT Universal screening is a key element of multi‐tiered systems of support. Relative to literacy, fewer studies have investigated the psychometric properties of math assessments particularly amongst middle school students. We investigated whether outcomes from two types of curriculum‐based measures (CBMs), computational fluency (M‐COMP) and ...

Psychology in the Schools, Volume 63, Issue 2, Page 457-470, February 2026.ABSTRACT This study compared the extent to which growth on two types of early math assessments (curriculum‐based measures [CBMs] and computer adaptive tests) predicted end of year performance in broad math skills as well as improvement in broad math skills in Kindergarten (n = 211) and Grade 1 (n = 79) students.

Wind Energy, Volume 29, Issue 2, February 2026.ABSTRACT This paper provides improvements to a previously presented simple, accurate, lower order analytical model for predicting the performance of horizontal‐axis shrouded turbines for a wide range of shroud airfoil shapes varying in length, camber, and thickness. The new, extended model incorporates explicit quantitative predictions of those effects

Modeling Interactions and Dynamic Saturation Processes in Karst Media
Water Resources Research, Volume 62, Issue 2, February 2026.Abstract The simulation of karst aquifers is highly challenging due to complex conduit‐matrix interactions. This study utilizes KarstFOAM, a high‐fidelity, physics‐based numerical model, to address these challenges. KarstFOAM integrates (a) a unified single‐domain Forchheimer–Darcy–Brinkman–Stokes (FDBS) formulation that transitions naturally across ...
