Abstract: A pharmaceutical composition for treating leukemia, including by weight 2 to 8% of realgar, 25 to 42% of indigo naturalis, 50 to 60% of salvia miltiorrhiza, and 6 to 10% of heterophylla.

Abstract: A pharmaceutical composition for treating leukemia, mainly made of the following raw materials by weight percentage: 2 to 8 percent of realgar, 25 to 42 percent of indigo naturalis, 50 to 60 percent of salvia miltiorrhiza, and 6 to 10 percent of heterophylla. The present disclosure improves the preparation method of salvia miltiorrhiza, reduces the amount of the adding water, the number of decocting times and the decocting time. Tanshiuone IIA extraction rate reaches 75%. The pharmaceutical composition of the present disclosure can treat leukemia, the complete remission rate reaches 92.9%, the curative effect is obviously improved, and the toxic side effects are greatly reduced.

Abstract: The present invention provides a method of power control for a plurality of secondary users (SUs), or unlicensed users, in a cognitive radio network having a plurality of primary users (PUs), or licensed users. The method comprises determining an optimal power level for each of the SUs such that a total throughput of all the SUs is maximized while satisfying an individual throughput requirement of each SU and an interference limit constraint of the PUs. In particular, a case having two SUs is considered.

Abstract: A communication system and a method for transmitting data over a communication network includes a processing module arranged for selectively splitting a traffic demand of a transmission link into a plurality of portions of traffic demands distributed over a main channel and at least one auxiliary channel of the communication network, and the processing module is further arranged to determine a data transmission relationship associated with the traffic demand of the transmission link and at least one parameter of both the main channel and the at least one auxiliary channel; and a transmission module arranged to transmit data over one or more of the main channel and the at least one auxiliary channel according to the data transmission relationship.
