Isometric training at longer muscle–tendon complex lengths: A potential countermeasure to impaired neuro‐muscle–tendon function during space travel

Experimental Physiology, EarlyView.
Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...

Ballistic performance of hybrid composite structures

, 2021
The aim of this study is to numerically investigate the ballistic behavior of composites with different thicknesses and different reinforcements. The guns were shot at four different velocities on composite models using armor-piercing 7.62 M61 AP projectiles.

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

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

Dosimetric and clinical validation of a high‐density bolus for superficial skin tumors treated with radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Accurate dose deposition in superficial radiotherapy remains challenging due to the inherent skin‐sparing effect of megavoltage photon beams and difficulties in ensuring bolus conformity. Purpose This study aims to comprehensively evaluate the dosimetric characteristics of the room‐temperature‐malleable high‐density bolus, to ...

Quaternary Climate Oscillations Shape Genetic Diversity and Spatial Structure of Viola hybanthoides (Violaceae) Endemic to Danxia Landscape

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.

Parametric Study of Phosphogypsum‐Rock Wool‐Phosphogypsum Sandwich Lightweight Partition Wallboards Under Impact Load

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 ...
