Thruster configuration dictates the hydrodynamic stability of underwater welding vehicles, yet standard design protocols rarely penalize undesired forces and moments that compromise precision. This study proposes a multi-index performance evaluation framework that integrates propulsion capability and disturbance minimization into a unified metric. Key indices include the Propulsion Index (PI), Balance Improvement Index (BI), a...

This study explored the potential of bamboo vinegar powder (BVP) to mitigate hepatic injury and metabolic disturbance induced by a high-starch diet in largemouth bass ( Micropterus salmoides ). Fish were distributed into three groups (with three replicates per group) and fed for 56 days with a basal diet (BD), a high-starch diet (CSD), and the BVP-supplemented diet (CSDB, added 2.0 g/kg BVP to the CSD diet), respectively. Afte...
