In the scenario where the dark matter(DM) particles χχˉ pair annihilate through a resonance particle R,the constraint from DM relic density makes the corresponding cross section for DM-nuclei elastic scattering ext...
An innovative lower extremity exoskeleton with hybrid leg structures is proposed in this paper. The compound pendulum model is applied to analyze the swing motion during walking for the wearer and the exoskeleton resp...
