This study addresses the control challenge of ventilated supercavitating vehicles during depth-change maneuvers, where variations in speed and depth induce unsteady cavity evolution and nonlinear planing forces. An unsteady cavity evolution model based on the independent cross-sectional expansion principle was developed and integrated with vehicle dynamics to form a heterogeneous coupled motion framework. A DQN-based controlle...

Backgrounds Methylmercury (MeHg) is regarded as a developmental neurotoxicant but the detailed mechanism remains not completely clear. Methods The Xenopus laevis embryos were exposed to methylmercury chloride and the expression of neurodevelopment and oxidative stress genes was detected by qRT-PCR or Western blotting. PC12 cells were exposed to various levels of H 2 O 2 , and then cell cycle, neurite length, neurodevelopment-r...
