  • Patent number: 12211267
    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: 20240393977
    Abstract: A memory device includes a memory array configured as quad-level cell (QLC) memory and a control logic operatively coupled to the memory array. The control logic identifies a first two bits of particular pages of a QLC logical state. The control logic causes memory cells of the memory array to be coarse programmed with a threshold voltage distribution of a multi-level cell (MLC) logical state corresponding to the first two bits. The control logic reads the MLC logical state from the memory cells and a second two bits from a cache buffer to determine the QLC logical state. The control logic causes the memory cells to be further coarse programmed with a QLC threshold voltage distribution corresponding to the QLC logical state.
