  • Publication number: 20180362712
    Abstract: Disclosed is a Y-type discrete polyethylene glycol derivative as shown by Formula (I). The Y-type discrete polyethylene glycol derivative has the advantages of a determined molecular weight and number of segments in the chain, and can avoid the defects where the polyethylene glycol derivative itself is a mixture and the molecular weight is not homogeneous. The Y-type polyethylene glycol of the present invention can solve the problem of insufficient water solubility caused by an increase in the loading capacity when the discrete polyethylene glycol modifies an insoluble drug while increasing the drug loading capacity.

  • Publication number: 20180331673
    Abstract: Differing from the fact that the amount of register units and adder units arranged in conventional moving average filter must be increased for processing more number of reference input signals, the present invention particularly discloses a moving average low-pass filtering device. The moving average low-pass filtering device comprises a register unit and a filtering and processing unit, and is able to use identical circuit architecture to successfully treat reference input signals with a filtering process even if the number of the reference input signals is alternatively increased. Moreover, after finishing a verification experiment by a simulator, simulation results have proved that, this novel moving average low-pass filtering device still can use identical circuit architecture to complete the filtering process under nearly the same calculation efficiency even though the number of the reference input signals is alternatively increased.
