Bronchoscopy Robot with Enhanced Flexibility and Stability via Multi‐Segment Variable Stiffness Catheter

Advanced Intelligent Systems, EarlyView.
This work presents a magnetic bronchoscopy robot with a novel multi‐segment variable stiffness catheter. This catheter can not only move flexibly in the narrow bronchi but also harden according to the need to provide support. Combined with remote wireless magnetic field drive, it provides a more precise and effective solution for biopsy of deep lung ...

Navigating Whiteness in Australia's Anti‐Racism Movement: A Duoethnographic Inquiry by Women of Colour Scholars

Australian Journal of Social Issues, EarlyView.
ABSTRACT This paper applies Critical Race Theory (CRT) to explore how whiteness operates within Australia's anti‐racism movement as a structuring force that shapes discourse, practice and policy. Despite the anti‐racism movement offering crucial spaces for resistance and reform, it remains entangled in Australia's settler‐colonial present and systemic ...

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

Journal 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 critical buckling load for variable stiffness composites using the lamination parameters as the field variables

Buckling is a critical design concern for thin-walled structures and fiber-reinforced composite materials because it occurs with much lower strains than in failure. In this study, an in-house code is developed to optimize the critical buckling load using

Changing a Winning Team—Replacement of Brominated Flame Retardant and Antimony Trioxide in Acrylonitrile–Butadiene–Styrene

Journal of Applied Polymer Science, EarlyView.
This comprehensive study investigates reducing the amount of brominated flame retardant (Br) and/or antimony trioxide (ATO) in acrylonitrile–butadiene–styrene. Therefore, condensed‐phase flame‐retardant mechanisms are introduced into the flame‐inhibition system.

Dynamic buckling behavior of multi-walled carbon nanotubes subjected to step axial loading

, 2012
This paper studies the dynamic buckling behavior of multi-walled carbon nanotubes (MWNTs) subjected to step axial loading. A buckling condition is derived, and numerical results are presented for MWNTs under fixed boundary conditions.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Optimization of Arthroscopic All‐Inside Meniscus Repair With a Probe

Arthroscopy 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 ...

Critical load for torsional buckling of Kelvin-type digital materials

Abstract Torsional buckling is likely to occur when digital materials are subjected to axial compression. There is little research on the torsional buckling of digital materials, which can be easily overlooked in design and pose safety hazards in engineering applications.

Bridging home, school and community to address educational inequality: Supporting educational trajectories through community bridge work

British Educational Research Journal, EarlyView.
Abstract This paper explores the role of community stakeholders in supporting the educational trajectories of students experiencing socio‐economic disadvantage in the Irish context. Building on international and national policy debates, the study examines how community‐based organisations, statutory services and outreach initiatives work alongside ...
