Abstract: A live human face detection method includes: obtaining an image frame comprising a human face of a target object to be detected, obtaining texture information and deformation information corresponding to the human face in the image frame, performing feature extraction on the texture information through a live human face detection model, to obtain a texture feature, and performing feature extraction on the deformation information, to obtain a deformation feature; concatenating the texture feature and the deformation feature, to obtain a concatenated feature, and outputting a live human face prediction score through the live human face detection model based on the concatenated feature; and determining that the human face in the image frame is a live human face in response to that the live human face prediction score is greater than or equal to a live human face threshold.

Abstract: A method for mapping a packet service onto an optical transport network is disclosed. An embodiment of the method includes: receiving a packet service message from an access side, identifying the message by using a first board number of a first line board in which a first egress is located and a first port number of the first egress; sending the message to the first line board corresponding to the first board number; and encapsulating the message that is sent to the first line board, mapping the encapsulated message onto a first optical channel data unit ODU corresponding to the first port number, and sending the first ODU by using the first egress. Cross-connect scheduling of any bandwidth in any direction is implemented based on a packet service, and packet services on different tributary boards share different ODU timeslots or a same ODU timeslot on a same line board.

Abstract: The present invention provides a method for enrichment and isolation of endogenous transcription factors and their complexes. Also, this invention provides corresponding tandem arrays of concatenated transcription factor response elements (catTFRE). The method employs the property of transcription factors binding to sequence-specific DNA elements during regulation of gene expression. The catTFREs are designed and synthesized as concatenate dual copies of DNA response elements for various transcription factors. The DNA sequence of synthesized catTFRE is cloned to a target vector. Biotinylated catTFRE with 200 bp arms is prepared by PCR strategy. For enrichment and isolation of endogenous transcription factors and their complexes, the biotinylated catTFRE is immobilized to streptavidin-coated magnetic beads and then incubated with nuclear extract. Thereby endogenous transcription factors and their complexes are isolated from nuclear extract.

Abstract: Methods and devices for implementing Link Pass Through in a point-to-multipoint network in respect of the network reliability field are provided. Embodiments of the present invention are applicable to a network having an access gate, an access device, an aggregation device and a router. When a failure occurs in an active link between the access device and the aggregation device or between the aggregation device and the router, the access device breaks the connection between the access device and the access gate enables a standby link to conduct communication. Advantageously, when a failure occurs in the active link between the access device and the aggregation device or between the aggregation device and the router, the access device may break the connection between the access device and the access gate and the access gate may enable a standby link to conduct communication.

Abstract: The invention discloses a flow control method for VC-Trunks in metropolitan-area network equipment. The method at least includes following steps: Receiving-end transmission equipment determines whether there is a service data packet block in its VC-Trunk, if it is, a flow control packet with the VC-Trunk tag is sent out; The transmission equipment that has received the flow control packet pauses service data packets forwarding of the VC-Trunk according to the VC-Trunk tag in the flow control packet until the timing brought in by the flow control packet is ended and there is no other new flow control packet coming. The method can individually control data flow for each VC-Trunk, and comparing with the present technique the method solves problems that there is no flow control in SDH.
