Hyperelastic swelling of stiff hydrogels

Posted by dbos January 8, 2024Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Justin C. Burton, , , | Summary: Hydrogels are biphasic, swollen polymer networks where elastic deformation is coupled to nanoscale fluid flow. As a consequence, hydrogels can withstand large strains and exhibit nonlinear, hyperelastic properties. For low-modulus hydrogel and semiflexible biopolymer networks, previous studies have […]

Optically Helicity-Dependent Orbital and Spin Dynamics in Two-Dimensional Ferromagnets

Posted by dbos January 8, 2024January 22, 2024Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Shuo Li, Ran Wang, Thomas Frauenheim, Junjie He, | Summary: Disentangling orbital (OAM) and spin (SAM) angular momenta in the ultrafast spin dynamics of two-dimensional (2D) ferromagnets on subfemtoseconds is a challenge in the field of ultrafast magnetism. Herein, we employed non-collinear spin version of real-time time-dependent […]

LightHouse: A Survey of AGI Hallucination

Posted by dbos January 8, 2024Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, , , , | Summary: With the development of artificial intelligence, large-scale models have become increasingly intelligent. However, numerous studies indicate that hallucinations within these large models are a bottleneck hindering the development of AI research. In the pursuit of achieving strong artificial intelligence, a […]
