  • Publication number: 20220415044
    Abstract: The present disclosure provides a method, apparatus, medium and device for extracting a river drying-up region and frequency, and belongs to the technical field of remote sensing. The method for extracting a river drying-up region and frequency can be applied to efficiently acquiring river drying-up information for a long time within the large spatial region. With the inverse normalized difference water index (iNDWI) and the maximum value composite (MVC) method for the remote sensing images, the present disclosure omits the troublesome step of separately extracting a river range for each image in the conventional method. In addition, the present disclosure quickly obtains the drying-up frequency by counting the total number of available images and the number of non-water images at the same pixel position, and yields a greater efficiency for extracting the river drying-up region and frequency.

  • Publication number: 20220056479
    Abstract: Disclosed is a method for delivering a gene into target cells, wherein immune cells are used as a vector for virus packaging and transportation to complete the delivery of biomacromolecules among cells, and thus change original characteristics of the target cells or generate new characteristics in the target cells. The gene delivery system, on one hand, can kill target cells such as tumor cells by utilizing the specificity of immune cells; and on the other hand, can modify genes of cells in a lesion by gene delivery to target cells, to directly kill the target cells.
