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

open access: yesJournal of Applied Polymer Science, EarlyView.
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

Optimization of Arthroscopic All‐Inside Meniscus Repair With a Probe

open access: yesArthroscopy Techniques, EarlyView.
Abstract Meniscal preservation is essential for knee function and long‐term joint health. All‐inside meniscus repair achieves outcomes comparable to the inside‐out technique, but technical challenges remain, including limited working space, suture cut‐out in degenerative tissue, unfavorable suture angles, and risk of cartilage injury or arthroscope ...

Distortional lateral torsional buckling for simply supported beams with web cleats [PDF]

open access: yesCanadian Journal of Civil Engineering, 2015
Critical moment expressions for steel beams based on elastic lateral torsional buckling as given in classical solutions and present standard provisions are based on assumed fully restrained support conditions and simplifying kinematic assumptions that neglect distortional effects.

Anatomical Study of Lateral Compression II Screw Path and Entry Parameters Based on Three‐Dimensional CT Image Reconstruction Techniques

open access: yesOrthopaedic Surgery, Volume 17, Issue 5, Page 1454-1463, May 2025.
This graphical abstract illustrates a study where 43 adult patients (21 males, 22 females) underwent CT scans to reconstruct 3D pelvic models using Mimics and 3‐Matic software. The analysis measured the Lateral Compression II (LC‐II) screw path, revealing sex‐based anatomical differences that could improve the precision and safety of percutaneous LC‐II

Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 12, 23 June 2026.
Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...
