Commuting Pairs in Quasigroups
Journal of Combinatorial Designs, Volume 33, Issue 11, Page 418-427, November 2025.ABSTRACT A quasigroup is a pair ( Q , ∗ ), where Q is a nonempty set and ∗ is a binary operation on Q such that for every ( a , b ) ∈ Q 2, there exists a unique ( x , y ) ∈ Q 2 such that a ∗ x = b = y ∗ a. Let ( Q , ∗ ) be a quasigroup. A pair ( x , y ) ∈ Q 2 is a commuting pair of ( Q , ∗ ) if x ∗ y = y ∗ x.

Meta‐Metamodelling of Engineering Systems by Help of Abstract Mathematics
Mathematical Methods in the Applied Sciences, Volume 48, Issue 16, Page 14815-14827, 15 November 2025.ABSTRACT The growing trend of automation in engineering significantly increases the complexity of engineering systems and necessitates a deeper understanding of the coupling of physical and cyber components interacting within the systems. A typical example of such a highly coupled system is an autonomous construction site, where robotic systems aim to ...

Psychology 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
Geophysical 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

Amphibious Generator via Mechanical Coupling for Versatile Energy Harvesting
Advanced Energy and Sustainability Research, Volume 6, Issue 10, October 2025.An amphibious hybrid triboelectric nanogenerator–electromagnetic generator (TENG–EMG) efficiently harvests energy from wind and water. By integrating TENG and EMG units with a gear‐assisted mechanism, it enhances power output and powers small electronic devices.
