摘要： Integrin-linked kinase (ILK) and Akt/protein kinase B (PKB) are important mediators of signaling in cardiomyocytes and can both prevent damage and promote healing associated with ischemic injury to the heart. Thus, the present invention provides for methods of screening for agents that increase the expression of ILK and/or Akt/PKB. Methods of treatment based on such agents are also provided.

摘要： A method and network element include receiving, at a receiver node, at least one of sender timestamps and sequence numbers in continuity check (CC) frames sent by a sender node; determining receiver timestamps at the receiver node; detecting instability based on one or more of the at least one of sender timestamps and sequence numbers and the receiver timestamps; and performing a remedial action based on the detecting instability. The CC frames can include Bidirectional Forwarding Detection (BFD) or Continuity Check Message (CCM) frames which are regularly transmitted in a session, but do not currently include timestamps or sequence numbers.

摘要： An apparatus and method for video fingerprinting are provided. The method includes, for each frame of a video sequence including a plurality of frames, removing a portion of the frame, dividing a remaining portion of the frame into blocks, dividing each block into sub-blocks, computing a block level feature as a mean of pixels in each sub-block within the block, concatenating all block level features in the frame, and concatenating features of all frames in the video sequence.

摘要： A method and apparatus encode and decode video by determining whether to use discrete cosine transform (DCT) and DST for each of the horizontal and vertical transforms. During encoding, an intra-prediction is performed based on an intra-prediction mode determined for an M×N input image block to obtain an M×N intra-prediction residue matrix (E). Based on the intra-prediction mode, each of a horizontal transform and a vertical transform is performed using one of DCT and DST according to the intra-prediction mode. During decoding, the intra-prediction mode is determined from an incoming video bitstream. The M×N transformed coefficient matrix of the error residue is obtained from the video bitstream using an inverse quantizer. Based on the intra prediction mode, one of DCT and DST is performed for each of an inverse vertical transform and an inverse horizontal transform.

摘要： A method, a network element, and a network include determining an authentication mechanism between two nodes in a network path; operating the network path; performing connectivity check between the two nodes in the network path; and authenticating specific frames in the connectivity check between the two nodes with the authentication mechanism responsive to the specific frames affecting a state of the network path. The frames can be Bidirectional Forwarding Detection (BFD), Continuity Check Messages (CCMs), etc. Advantageously, the method, network element, and network reduce the computational load of providing authentication while maintaining secure authentication for important frames, i.e., ones that affect the state of the network path.
