Abstract: The present disclosure relates to the technical field of multimedia, and in particular, to a control method and apparatus for multimedia content display, an electronic device, and a medium. First multimedia content is displayed on a first page; and in response to a terminal device changing in a preset attitude, the first page is switched to a second page, and second multimedia content is displayed on the second page. That is, the switching of the first page to the second page is implemented by triggering the attitude change of the terminal device, thereby improving the interestingness of user interaction.

Abstract: This application discloses a call method and system, and a related apparatus. When a specific condition is met (for example, a callee fails to be paged), a network device forwards, to a VoIP server, a first call request to a target number, where the first call request is a call request initiated by a calling terminal to the target number, and the target number has been subscribed to a call forwarding service. Then the VoIP server parses a forwarding message from the network device to obtain a called number, searches, based on the called number, for the called terminal associated with the called number, and initiates a VoIP call to the called terminal, so that the callee in an out-of-service state (for example, there is no signal of an operator network or the callee is in an airplane mode) can still receive the call request from the caller.

Abstract: The invention discloses an anti-phenacetin monoclonal antibody hybridoma cell strain AD, a preparation method and application thereof, and relates to the technical field of food safety immunodetection. The monoclonal antibody hybridoma cell strain is named monoclonal cell strain AD and the number CGMCC19681. The Phe-BA obtained by the hydrolysis of the reaction product of the phenacetin metabolite acetaminophen and ethyl 4-bromobutyrate is used as the hapten, and the hapten is coupled with the carrier protein to prepare the immunogen Phe-BA-BSA. After the mice were immunized with the immunogen Phe-BA-BSA, they were fused with myeloma cells by PEG method, screened by indirect competitive enzyme-linked immunosorbent assay and subcloned five times to obtain hybridoma cell lines. The monoclonal antibody secreted by the cell line can be made into a phenacetin detection kit, which has good affinity and detection sensitivity for phenacetin, and can be used for immunodetection of phenacetin residues in food.

Abstract: A method for generating and check-controlling a network identity identification code in a network electronic identity is provided for the establishment of a unified network identity management and service ecosystem that effectively protects the network application security and identity information privacy of citizens. A server performs initialization and generates and distributes random numbers while receiving and auditing a request to generate a network identity identification code from a client. If the client passes the audit, encryption coding is performed and a network identity identification code is generated and sent to a network electronic identification card through the client. The network electronic identification card performs check processing of the network identity identification code, and feeds back a result to the server. The server stores the network identity identification code into a database, and informs the user.

Abstract: One of the common channels of the GSM system is the paging channel (PCH) for alerting the mobile station of an incoming call. The PCH message is scattered among four bursts as a result of coding, interleaving, and mapping processes before transmission. It is a waste of power for a handset to turn on and analyze all four bursts if the PCH message is a dummy one. Ideally, a handset needs to be able to make a determination whether a PCH message is a dummy one in as short of a time as possible and, if it is, turn off the power. Embodiments of this invention include methods and apparatus for enabling a handset to make this determination by merely analyzing the first received burst. Since most of the PCH messages are dummy ones, the proposed methods will cause noticeable savings in the power consumption of the GSM handsets.
