Hyperelastic swelling of stiff hydrogels

Posted by dbos Peking

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 Peking

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 […]

Inferring the redshift of more than 150 GRBs with a Machine Learning Ensemble model

Posted by dbos Stanford

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Maria Giovanna Dainotti, Elias Taira, Eric Wang, Elias Lehman, Aditya Narendra | Summary: Gamma-Ray Bursts (GRBs), due to their high luminosities are detected up to redshift 10, and thus have the potential to be vital cosmological probes of early processes in the universe. Fulfilling this potential requires […]
