Buckling of a Nonlinearly Elastic Column: Variational Principles, Bifurcation and Asymptotics
Rocky Mountain Journal of Mathematics, 1995 We study the equilibrium states of an elastic column subject to an end thrust. The column is modeled as an inextensible rod with a nonlinear moment-curvature equation. We bring various mathematical theories to bear on this problem; the calculus of variations, bifurcation theory, phase plane analysis, and singular perturbation theory for ordinary ...

Bio‐Inspired Micro‐Fin‐Assisted Multi‐Modal Vascular Intervention
Advanced Science, Volume 13, Issue 8, 9 February 2026.A magnetic guidewire with a micro‐fin–integrated tip is introduced for multimodal cardiovascular navigation. The micro‐fins exploit fluid drag to augment magnetic torque, enabling bifurcation traversal at 15 mT, tolerating 45° misalignment, bidirectional crawling, and buckle self‐correction.

Entangled Multistable Origami with Reprogrammable Stiffness Amplification and Damping
Advanced Functional Materials, Volume 36, Issue 5, 15 January 2026.This study introduces a class of origami‐inspired metamaterials that overcome the limitations of existing multistable metamaterials by eliminating the need for rigid lateral confinements. Panel entanglement, snap‐through interactions, and instabilities synergy enable them to achieve extensive shape‐shifting, enhanced stiffness, and remarkable energy ...
