Limit Cycles of Continuous–Discontinuous Piecewise Linear Hamiltonian Systems in ℝ2 Separated by the Curve y=sinx

Mathematical Methods in the Applied Sciences, Volume 49, Issue 3, Page 2093-2097, February 2026.
ABSTRACT These last decades piecewise differential systems have been studied intensively, mainly due to their applications. Inside the study of the dynamics of these differential systems, the limit cycles, that is, the isolated periodic orbits inside the set of all periodic orbits of the system, play a main role.

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.

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 ...
