Abstract: Method and system for detecting disease in blood sample is described. By extracting extracellular vesicles (EVs) from the blood sample and employing liposome fusion probes, it is shown that the test can be completed within hours instead of weeks, and the detection limit can be significantly lowered.

Abstract: An access control method. A BNG CP may receive a first message from first user equipment. The first message is used by the first user equipment to request to access a network, a primary gateway through which the first user equipment accesses the network is a first BNG, and a backup gateway through which the first user equipment accesses the network is a second BNG. After receiving the first message, the BNG CP may determine, from a first network segment, an IP address assigned to the first user equipment, and send the IP address of the first user equipment to the first user equipment. The first network segment is only used to assign an IP address to user equipment that accesses the network by using the first BNG as a primary gateway and the second BNG as a backup gateway.
