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.

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.

Abstract: The present disclosure relates to fabricating sacrificial microfiber templates from any biocompatible and resorbable materials depending on the time needed for dissolving the microfiber template to free the endothelial tube with open lumen. Microfiber networks with distinct patterns and defined diameters initially serve as a template to support the growth of vascular cells (endothelial cells or their progenitor cells, or combined with mural cells such as pericytes) and then dissolve to form an empty endothelium lumen. The incorporation of sacrificial microfiber networks encapsulated with vascular cells into 3D cell-rich constructs allows for the creation of various vascularized tissues.
