Wave Propagation in Non‐Uniform Media by Linear Expansion of the Refraction Law
ABSTRACT The propagation of mechanical waves in an unbounded, non‐uniform medium can be described by using curvilinear coordinates centered at the source position. The Frenet coordinate system, with origin on a point riding a wave, is used as a basis for the curvilinear coordinates.

Numerical and Analytical Study of Elastic Parameters in Linearized Micropolar Elasticity
ABSTRACT The effect of elastic parameters in the linearized theory of micropolar elasticity on observable deformation is analyzed analytically and numerically. Specifically, a shear deformation boundary value problem is studied to explore the physical implications of a micropolar formulation. Our new analytical solution for the two‐dimensional shearing

This meta‐analysis of 25 studies (17,628 children) shows a substantial decline in gastrointestinal parasitic infections in Nepal from 43.4% to 24.2% between 2004 and 2022. Helminths (20.0%) remained more common than protozoa (9.9%), with slightly higher prevalence in urban (29.0%) than rural areas (27.9%). ABSTRACT Background Gastrointestinal parasitic

ABSTRACT This article examines the persistence and transformation of patriarchal–feudal structures in Polish art universities in the context of post‐1989 higher education (HE) reforms. Drawing on 22 in‐depth interviews with socially engaged academic staff (18 women and four men) across 11 Polish artistic institutions, the study explores how ...

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.
