Stiffness‐Programmable Origami Robots With Tendon‐Driven Actuation via Multimaterial 3D Printing
Advanced Robotics Research, EarlyView.Motion diversity is achieved in a tendon‐driven origami robot through programmable stiffness rather than modified actuation. Multimaterial 3D printing embeds soft creases, modular inserts redirect identical tendon inputs into distinct behaviors, and variable‐stiffness inserts enable real‐time switching.

Accordion effect – Lesson for a novice interventionist during angioplasty
Journal of Indian College of Cardiology, 2014 Abstract Accordion effect is a transient appearance of stenotic lesions after crossing the guidewire in a tortuous vessel during percutaneous coronary intervention. Removal of the guide wire normally leads to the complete resolution of these lesions. Young interventionists should be aware of this effect, in order to avoid misinterpretation and hence ...
