Clinical application and efficacy of phrenic nerve transferring to the anterior division of upper trunk of brachial plexus for treatment of the brachial plexus injury;

This paper analyzes on the riverbed evolution of the upper reaches mainstream of the Fenhe River, reviews the control situation of the stream channel, and analyzes on the main problems existing in the control starting from the embankment works and the roller-way project, and advances the tasks and principles of the control of the stream channel.

The effect of filter bandwidth in soft limiting satellite transponder with uplink interference is studied.

Taking example by direct sequence spectrum spreading system, firstly the link performance of transparent transponder satcom system is analyzed with uplink interference (or jamming) and then the theory derivation is made.

Firstly the performance of transparent transponder satcom system is analyzed to uplink interference (or jamming) and the closed expression for calculating BER performance is given.
