Effects of the Accelerating Mathematics Performance With Practice Strategies (AMPPS) Intervention Program When Delivered During Summer in a One‐On‐One Virtual Format

open access: yesPsychology in the Schools, Volume 62, Issue 11, Page 4725-4739, November 2025.
ABSTRACT Despite extensive research suggesting the importance of students developing strong foundational math skills during early grades, more than 60% of 4th graders in the United States lack proficiency in mathematics. Such data are influenced by several factors, including summer learning loss in math, negative impacts from the COVID‐19 pandemic, and

Tensor Analysis of Tropical Cyclone Boundary Layer Turbulence

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Turbulent momentum transport critically influences tropical cyclone (TC) structure and intensity, but its multiscale characteristics remain poorly understood. Using two large eddy simulations, we investigate the Reynolds stress tensor and subfilter‐scale momentum flux tensor during rapid intensification and mature stages of an idealized TC. We

Characterization of the In Situ Stress State of Blood Clots in Ischemic Stroke: The Effect of Initial Conditions and Arterial Interaction

open access: yesInternational Journal for Numerical Methods in Biomedical Engineering, Volume 41, Issue 10, October 2025.
Ischemic stroke is a leading cause of death worldwide, yet clot lodging mechanics remain poorly understood. Most in silico studies assume a stress‐free clot, though both the clot and artery are likely in a pre‐stressed state at the point of thrombectomy procedures.

Microstructural Evolution, Performance, and Triboelectric Response of Cu–Fe Composites Processed via Deformation‐Driven Metallurgy

open access: yesEngineering Reports, Volume 7, Issue 10, October 2025.
Microhardness reached a maximum of 158.5 ± 3.9 HV at 4 wt.% Fe, with tensile strength peaking at 331.9 ± 9.9 MPa, whereas higher Fe addition (6 wt.%) caused microhardness and tensile strength to decline to 142.4 ± 4.8 HV and 294.7 ± 9.2 MPa, respectively, due to particle clustering and thermal softening.

On Endomorphism Universality of Sparse Graph Classes

open access: yesJournal of Graph Theory, Volume 110, Issue 2, Page 223-244, October 2025.
ABSTRACT We show that every commutative idempotent monoid (a.k.a. lattice) is the endomorphism monoid of a subcubic graph. This solves a problem of Babai and Pultr and the degree bound is best‐possible. On the other hand, we show that no class excluding a minor can have all commutative idempotent monoids among its endomorphism monoids. As a by‐product,

A Dichotomy Theorem for Γ‐Switchable H‐Colouring on m‐Edge‐Coloured Graphs

open access: yesJournal of Graph Theory, Volume 110, Issue 2, Page 200-208, October 2025.
ABSTRACT Let G be a graph in which each edge is assigned one of the colours 1 , 2 , … , m, and let Γ be a subgroup of S m. The operation of switching at a vertex x of G with respect to an element π of Γ permutes the colours of the edges incident with x according to π.
