Abstract: A payment bill query request initiated by a user through a third-party payment platform is obtained at a payment platform server. Whether a payment institution has generated a payment bill for the user is determined based on the payment bill query request, where the payment institution does not provide the third-party payment platform with bill generation information. If so, user information associated with the user is obtained by the payment platform server and based on the payment bill. Whether information for notification that the payment institution has generated the payment bill for the user has been pushed to the region that the user belongs to is determined. If not, the information for notification that the payment institution has generated a payment bill is pushed to each user associated with the third-party payment platform within the region that the user belongs to through an account of the third-party payment platform.

Abstract: The present disclosure discloses a shift register and a driving method thereof, a gate driving circuit, an array substrate, and a display device. With a signal control circuit, a branch control circuit, a cascade signal output circuit and at least two scanning signal output circuits, each shift register can output at least two different scanning signals to correspond to different gate lines in an array substrate. This can reduce the number of shift registers in a gate drive circuit and the space occupied by the gate drive circuit and can achieve an ultra-narrow bezel design, as compared with an existing shift register that can only output one scan signal. Furthermore, as signals of different output control node do not influence each other, the stability of waveforms of the output scanning signals may also be improved, and a difference in the waveforms of the scanning signals is avoided.

Abstract: A server may receive an authentication packet from a Forwarder via a data channel. Where, the server enables a BRAS control plane function and the Forwarder enables a BRAS forwarding plane function. The server authenticates the authentication packet. When the authentication is successful, a session entry for instructing the Forwarder to forward a data packet is created, and the session entry and an identity of the data channel are transmitted to the Forwarder through a protocol connection paired with the data channel.

Abstract: Disclosed is an image analysis method and apparatus, upon a program crash on a computing node, the central node may acquire the image analysis task that results in the crash, split the image analysis task into multiple image analysis sub-tasks, transmit sequentially the image analysis sub-tasks to the computing node until a program crash occurs thereon. The central node then acquires an error image analysis sub-task that results in the crash on the computing node, and discard the error image analysis sub-task. The image analysis method can discard only the crash resulting image from an image analysis task, while other images in the image analysis task are retained. As such, fewer images are lost, so that the duration of a frame loss during video playback can be reduced and the reliability of image analysis can be improved. The approach is applicable for image analysis.
