Effect of Polyurethane Colloid Content on the Ballistic Performance of Prepreg PBO Fiber Composite Laminates

open access: yesGaoya wuli xuebao
To address the issue of weak interfacial bonding and insufficient ballistic performance in poly-p-phenylene ben-zobisoxazole (PBO) fiber composites caused by the chemically inert fiber surface, the waterborne polyurethane impregnation followed by a hot ...

Contextual Learning of New Meanings for Familiar Words: Perturbation of Original Meanings Occurs Without Deliberate Study

open access: yesLanguage Learning, EarlyView.
Abstract The present study investigated learning new meanings of known words from reading, following Hulme et al.’s (2018) study. English speakers read four short stories containing 16 critical words (i.e., familiar word forms assigned invented secondary meanings).

Computational Modeling of Decision Making Enhances the Adversity Researcher's Toolbox

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Over the past decades, there has been major progress in our understanding of how adversity influences cognitive abilities and strategies. However, most of this research is based on raw performance, such as response times and accuracy. These measures are informative about decision‐making outcomes but tell us little about cognitive processes. In

Common inputs to motor units are modulated by force profile and muscle length

open access: yesExperimental Physiology, EarlyView.
Abstract Groups of motor units receive common synaptic inputs from specialized networks of premotor neurons to produce movement. Here, we test whether common inputs received by motor units in the first dorsal interosseous are fixed or task‐dependent during submaximal isometric contractions.

Simulation and Analysis of Stiffened Auxetic Honeycombs Having Enhanced High Impact Velocity Response

open access: yesApplied Research, Volume 5, Issue 5, October 2026.
The ballistic resistance of auxetic re‐entrant honeycomb structures can be significantly improved through geometric tailoring and structural reinforcement. Vertical and horizontal stiffening ribs enhanced the ballistic performance, increasing the energy absorption efficiency by 119.45% and the projectile velocity reduction by 281.36%, ultimately ...
