The infectious hypodermal and haematopoietic necrosis virus (IHHNV) represents a significant viral threat to global shrimp aquaculture, leading to considerable economic losses. In this study, we have developed a one‐step, one‐pot isothermal assay for the detection of IHHNV, employing recombinase‐aided amplification in conjunction with clustered regularly interspaced short palindromic repeats‐Cas12a (RAA‐CRISPR/Cas12a). The ass...

The stern rudder of an underwater vehicle has a significant impact on the wake field and the flow noise. Hence, it is important to optimize the design of the stern rudder for reducing the radiated noise. In this work, a numerical model is set up to predict the flow noise of the underwater vehicle, based on the LES turbulence model and FW-H acoustic analogy method. After the verification study, the numerical prediction of the f...

Gerbils are a subfamily of rodents living in arid regions of Asia and Africa. Recent studies have shown that several gerbil species have unusual amino acid changes in the PDX1 protein, a homeodomain transcription factor essential for pancreatic development and β-cell function. These changes were linked to strong GC-bias in the genome that may be caused by GC-biased gene conversion, and it has been hypothesized that this caused...
