Abstract: Provided are a polypeptide for promoting angiogenesis and a composition including the polypeptide. The polypeptide for promoting angiogenesis provided by the present application includes at least one selected from the group consisting of the following (a) to (c): (a) a polypeptide in which a carboxyl terminus has a GRPRF (SEQ ID NO: 12) sequence; (b) a polypeptide in which there is a GKR cleavage site at a carboxyl terminus; and (c) a polypeptide in which there is an amidation modification at a carboxyl terminus. By binding to NPY-Y2R of the neuropeptide Y (NPY) receptor family, the polypeptide ZsTx can regulate the proliferation, migration, and tube formation of vascular endothelial cells to promote the angiogenesis.

Abstract: This document relates to natural language processing using a framework such as a neural network. One example method involves obtaining a first document and a second document and propagating attention from the first document to the second document.

Abstract: This application discloses when a first terminal device has performed a connection to a wireless access device based on a first channel (for example, a DFS channel), it may be determined whether both the first terminal device and a second terminal device support performing peer-to-peer communication in the first channel. When it is determined that both the configurations support establishing peer-to-peer communication in the first channel, peer-to-peer communication may be established based on the first channel. It can be ensured that a channel for communication between a device of at least one end and a wireless access device is the same as a channel for peer-to-peer communication, to effectively reduce occurrence of a scenario in which the terminal device performs time division switching between different channels, increase time for transmitting data in a peer-to-peer channel, and avoid a phenomenon like picture freezing, thereby improving user experience.
