Appendico‐Ileal Knotting; Case Series in Ethiopia
Clinical Case ReportsAppendico‐ileal knotting is an extremely rare complication of acute appendicitis, leading to obstruction when the inflammed appendiceal shaft wraps around the adjacent ileal segment and its mesentery. Diagnosis requires high clinical suspicion and urgent

Retained Percutaneous Tube—A Misery of Illiteracy
Asian Journal of Surgery, 2007 Percutaneous catheter drainage of liver abscesses is an established technique. Intracavitatory knotting of the tube is a rare and potentially preventable complication that can involve significant morbidity.

Knot Factories with Helical Geometry Enhance Knotting and Induce Handedness to Knots
Polymers, 2022 We performed molecular dynamics simulations of DNA polymer chains confined in helical nano-channels under compression in order to explore the potential of knot-factories with helical geometry to produce knots with a preferred handedness. In our simulations, we explore mutual effect of the confinement strength and compressive forces in a range covering ...

Soft Yet Tough Tanglemers Through Rapid Photopolymerization for DLP 3D Printing
Advanced Materials, EarlyView.Soft yet tough tanglemers are produced through low‐initiator free radical photopolymerization and translated to DLP 3D printing. Systematic control over light intensity, initiator loading, and crosslink density reveals processing windows that balance printability, elasticity, toughness, and feature fidelity. ABSTRACT Additive manufacturing of compliant

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Bioinspired Soft‐Skeleton Robotics With Cooperative Shape Transformation and Stiffness Adaptation
Advanced Robotics Research, EarlyView.A bioinspired soft‐skeleton robot that integrates variable‐stiffness chain skeletons into a soft textile skin is developed. The chain skeletons are highly flexible initially but can stiffen upon pneumatic actuation, enabling large deformation and enhanced load‐bearing capacity.
