Abstract: The invention relates to a method for preparing a simulated maternal cfDNA component for non-invasive prenatal testing, using a DNA fragmentation factor to digest a nucleus for simulating a maternal sample cell line, so as to obtain a simulated maternal cfDNA (short nucleic acid fragment) component. The reference material for non-invasive prenatal testing prepared by mixing different chromosome aneuploid cfDNA fragments with the normal chromosome number cfDNA fragments obtained by the present invention provides a method for manufacturing a reference material for internal quality control and external quality assessment. This method of making a reference material by mixing chromosome aneuploid cfDNA fragments and normal chromosome number cfDNA fragments produced with different enzyme digestions is the first case in the art. This method can also be used to make a series of mixed cfDNA sample reference materials for other noninvasive testing.

Abstract: The application relates to controlling access in a software-defined network (SDN). A controller in the SDN receives an access request from an application program. The controller determines whether an operation on a resource as specified in the access request belongs to a permission list corresponding to the application program. The permission list includes a list of permitted operations on the resource by the application program. When the operation as specified in the access request belongs to the permission list, the controller sends a reply message allowing access by the application program. In this way, accesses by the application program are restricted according to the permission list, and malicious attacks from the application program can be prevented to ensure network security.
