Abstract: A transmission control method in a satellite communication system and a related apparatus are provided. A terminal may determine, through satellite selection, a target satellite with a strongest signal from at least one satellite in geosynchronous orbit. The terminal may determine a satellite transmission link direction based on location information of the terminal and location information of the target satellite and may further determine a radiation direction of a satellite antenna in the terminal based on geomagnetic data and attitude data of the terminal. The terminal may enable, by using the satellite transmission link direction and the radiation direction of the satellite antenna, the radiation direction of the satellite antenna in the terminal to be aligned with the target satellite. After aligning with the target satellite, the terminal may send a first data packet to the target satellite along the radiation direction of the satellite antenna.

Abstract: The present disclosure relates to the field of tumor drug therapy, in particular to use of a methylaminocolchicine and salts thereof. The use includes use of a methylamino-substituted colchicine at C10 position and salts thereof in preparation of antitumor drugs, use thereof in antitumor drugs for antagonizing microtubule inhibitor resistance, or use thereof in combination an antitumor drug. In the present disclosure, the methylaminocolchicine and the salts thereof have significant antitumor effects, are more active than paclitaxel, vincristine, and colchicine, do not exhibit cross resistance to the paclitaxel and the vincristine, and inhibit paclitaxel-resistant cell growth in vivo. With in vivo acceptable therapeutic indexes, the methylaminocolchicine and the salts thereof have a synergistic antitumor effect when used in combination with an anti-apoptotic protein Bcl-2/Bcl-xL inhibitor.

Abstract: Embodiments of the present invention provide a method, system and server for delivering an advertisement based on user characteristic information. The method includes performing, by a server, data mining on user raw data corresponding to a client to obtain user characteristic information, generating a characteristic label based on the user characteristic information; determining, by the server, a type of advertisement according to the characteristic label, and delivering an advertisement of the type to the client. In the embodiments of the present invention, a great amount of user raw data is collected and stored in a server, data mining is performed on the user raw data, a characteristic label is generated based on user characteristic information obtained, and a network advertisement is delivered according to the characteristic label. Therefore, the advertisement can be delivered to particular users and the click ratio of the advertisement is increased.
