Abstract: The present disclosure discloses a method for extracting epidermal cells. The method includes soaking skin tissues in a digestive juice, and obtaining an epidermal cell suspension through alternate use of a high-temperature digestion condition and a low-temperature digestion condition. The method can be used for clinical research or treatment of burns, scalds, pigmentation and hypopigmentation, ulcers, aesthetic dermatology and the like. Through adjusting the digestion conditions of the skin tissues, the method separate the epidermis from the dermis within a relatively short time, and have the advantages of extracting epidermal cells in large amount, high survival rate and high activity. The extracted epidermal cells are applicable to various clinical indications.

Abstract: An antenna array decoupling method, apparatus and system, and a non-transitory computer-readable storage medium are disclosed. The method may include: receiving predetermined digital domain signals of a plurality of channels, each of the plurality of channels being a data channel corresponding to a respective one of array elements in an antenna array 5 (S110); determining decoupling factors of channels involved in decoupling corresponding to each channel, the decoupling factors being factors which have been solved for beforehand according to measured in-array pattern information of each array element in the antenna array (S120); and processing the predetermined digital domain signals of the channels involved in decoupling corresponding to each channel according to the decoupling factors to obtain a 10 decoupled predetermined digital domain signal of each channel (S130).
