Effects of Aging, Estimated Fitness, and Cerebrovascular Status on White Matter Microstructural Health

Human Brain Mapping, Volume 46, Issue 5, 01 April 2025.
White matter (WM) health declines with age and improves with estimated fitness. However, the effects of age and estimated fitness do not completely overlap spatially. Cerebrovascular health mediates the relationships of WM health with both age and estimated fitness. Males show steeper declines in WM health than females.

Doublet structural modeling of nonhomogeneous Euler mass sensor nanobeams using boundary characteristics Bernstein Polynomials

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 3, March 2025.
Abstract This study investigates the doublet structural model for analyzing nonhomogeneous Euler mass sensor nanobeams, incorporating the concept of doublet mechanics alongside Bernstein polynomials (BPs). BPs serve as basic functions within the Rayleigh–Ritz method, facilitating conversional governing equations into a geikneralized Eigenvalue problem.
