Pressure-driven wrinkling of soft inner-lined tubes

New Journal of Physics, 2022
A simple equation modelling an inextensible elastic lining of an inner-lined tube subject to an imposed pressure difference is derived from a consideration of the idealised elastic properties of the lining and the pressure and soft-substrate forces.

Laryngeal Cryotherapy for Neurogenic Cough: Safety, Feasibility, and Prospective Outcomes

The Laryngoscope, EarlyView.
A prospective clinical trial investigated the safety and clinical outcomes of office‐based selective laryngeal cryotherapy for patients with refractory chronic cough. Patient were followed for 6 months posttreatment and had durable improvement in cough severity index and urge‐to‐cough scores and no serious long term adverse effects.

On the bifurcation analysis of thin multilayer structures by the Asymptotic Numerical Method [PDF]

Journal of Theoretical, Computational and Applied Mechanics
This paper focuses on the stability analysis of multilayer thin shells using the asymptotic numerical method (ANM) combined with Padé approximants. This technique is highly effective for solving nonlinear problems due to its high-order algorithm that ...

Direct numerical simulations of three-dimensional surface instability patterns in thin film-compliant substrate structures

Scientific Reports, 2021
A comprehensive numerical study of three-dimensional surface instability patterns is presented. The formation of wrinkles is a consequence of deformation instability when a thin film, bonded to a compliant substrate, is subject to in-plane compressive ...

HDQ-based solution strategy for in-plane nonlinear buckling of shallow steel arches with linear elastic supports

Frontiers in Physics
This paper investigates the in-plane nonlinear buckling of shallow steel arches with linear elastic supports. Differential equations of equilibrium are built considering a virtual work principle. To balance computational accuracy, efficiency, and cost, a

Testing Times: A Structure/Agency Perspective on Becoming a Science Teacher in a Competitive, Exam‐Based Teacher Selection System

Science Education, EarlyView.
ABSTRACT While extensive research exists on science teacher shortages, less attention has been directed toward countries facing the opposite challenge: an oversupply of science teachers. This study examines the experiences of prospective science teachers in South Korea, where passing a high‐stakes, annual competitive examination is a prerequisite for ...

Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Maximum‐Entropy‐Based Meshless Modeling of Surface‐Tension‐Driven Large Deformation

International Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.
ABSTRACT Soft material modeling is challenging due, among others, to the substantial structural changes these materials undergo. In this context, meshless methods offer a promising alternative to overcome the limitations of established mesh‐based approximations such as finite elements. However, they introduce new challenges.

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

Advanced Intelligent Systems, Volume 8, Issue 9, September 2026.
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 ...
