This study presents a systematic airfoil optimization framework to enhance the hydrodynamic performance of vertical-axis tidal turbines (VATTs) under low-flow conditions. The integrated methodology combines parameterized design, response surface methodology (RSM) optimization, and high-fidelity computational fluid dynamics (CFD) validation to investigate the effects of maximum thickness (Factor A), maximum thickness position (...

Litopenaeus vannamei, a widely cultivated aquatic species worldwide, has its growth status intrinsically tied to the economic profitability of the aquaculture industry. However, infection by the microspondian parasite Enterocytozoon hepatopenaei (EHP) has emerged as a pivotal threat to the healthy growth of these shrimp. Through transcriptome sequencing, this study identified substantial alterations in gene expression patterns...
