  • Publication number: 20240182942
    Abstract: The preparation method for a polypeptide includes the steps of constructing an engineering strain for fusion-expressing a polypeptide gene with a Sumo tag, and inducing the engineering strain for the soluble expression of a polypeptide, obtaining a crude protein containing a polypeptide precursor from the engineering strain by purification, cleaving the crude protein containing the polypeptide precursor by a Ulp1 protease to remove the Sumo tag, and purifying a cleavage product of the Ulp1 protease by a method of acetonitrile combined with heating precipitation or a method of precipitation with hexafluoro isopropanol to obtain the polypeptide.

  • Publication number: 20240037950
    Abstract: The present application relates to a smoke detection method based on deep learning, a device and a storage medium. The method includes the following steps: performing image enhancement processing and color transfer processing on a smoke image to obtain a color transferred smoke image; superimposing the color transferred smoke image on an indoor image to obtain an initial image, and performing screening processing, detection frame updating processing, feature extraction and layer calibration processing on the initial image to obtain a smoke calibrated feature image; performing segmentation processing, detection frame prediction processing, detection frame classification processing and image classification processing on the smoke calibrated feature image in sequence to obtain a smoke image set; and screening the smoke image set to obtain a target smoke image, and outputting a smoke detection result. The present disclosure realizes the collection of smoke data sets and improves the detection accuracy of smoke.
