Journal of Applied Polymer Science, Volume 143, Issue 34, September 10, 2026.Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Strategic and Discursive Shifts in Türkiye's Perceptions of NATO, 1952–2020
Middle East Policy, Volume 33, Issue 3, Autumn (Fall) 2026.Abstract With crises intensifying across the Middle East, the Türkiye‐NATO relationship has become a matter of vital interest for global security. Employing a mixed‐methods approach, this study investigates shifts in Ankara's perceptions of NATO from the year of Türkiye's accession in 1952 through 2020. Officials’ views are examined through an analysis

Ecology and Evolution, Volume 16, Issue 8, August 2026.We adopted ddRAD‐seq and chloroplast genome sequencing to explore the genetic characteristics of the danxia‐endemic species Viola hybanthoides. This species exhibits extremely low within‐population genetic diversity and obvious genetic differentiation, which is mainly driven by habitat fragmentation, restricted gene flow and Quaternary climatic changes.

Engineering Reports, Volume 8, Issue 8, August 2026.Based on the validated LS‐DYNA model, this study carried out a series of simulations on Phosphogypsum‐Rock Wool‐Phosphogypsum (P‐RW‐P) sandwich lightweight partition wallboards under impact load. The effects of structural and impact load parameters on their impact performance of P‐RW‐P wallboards were systematically analyzed, providing a basis for the ...
