Bio‐Inspired Bidirectional Winding Origami With Programmable Modular Reconfigurability and Scalability

open access: yesAdvanced Science, EarlyView.
A bio‐inspired bidirectional‐winding origami platform enables scalable and programmable deployable structures. Double axial folding inspired by earwig hindwings and Flasher‐based hybridization create modular multilayer architectures with diverse attainable winding angles under fixed boundary conditions.

From Folding Mechanics to Robotic Function: A Unified Modeling Framework for Compliant Origami

open access: yesAdvanced Science, EarlyView.
A geometry‐consistent DDG framework captures compliant origami deformation from rigid‐like folding to soft panel bending. By tuning crease and panel stiffness, bistable snap‐through responses transform into smooth monostable deformation, enabling programmable stability and robot‐scale locomotion.

Terahertz‐Nanoscale Visualization of the Microscopic Spin‐Charge Architecture of Colossal Magnetoresistive Switching

open access: yesAdvanced Science, EarlyView.
This study employs cryogenic magneto‐terahertz nanoscopy to reveal the real‐space electrodynamics of the colossal magnetoresistance transition. By capturing the terahertz electrodynamic evolution of field‐driven spin switching, the work unveils the dissipative dynamics of emergent metallic states, providing a high‐frequency view of coupled spin‐charge ...

Partial Phase‐Separation in the Initial Growth Stage of Exsolution‐Active SrTi0.95‐xNi0.05NbxO3‐δ Thin Films

open access: yesAdvanced Science, EarlyView.
Phase separation emerges during the initial growth of heavily Ni‐ and Ni,Nb‐co‐doped STO thin films, leading to preferential accumulation of Ni and embedded NiOx nanoinclusions in thicker films. Nb co‐doping partially suppresses the ordering of these embedded structures, comprising about 20% of all Ni ions.

Children in the mountains

open access: yesBMJ, 1998
Editorial p 873 High altitude areas of the world were once visited only by a privileged minority. Now the great mountain ranges have become popular tourist destinations. An increasing number of children accompany their parents on such journeys, but little consideration has been paid to the potential risks of exposing young children to high altitudes.

Human Factors in High-Altitude Mountaineering [PDF]

open access: yes, 2015
We describe the human performance and cognitive challenges of high altitude mountaineering. The physical (environmental) and internal (health) stresses are first described, followed by the motivational factors that lead people to climb. The statistics of
