This Paper describes the principle and the adaptive model reference adaptive methods,based on the characteristics of doubly-fed wind generator design of a stator currents and rotor currents as state variables of the adaptive stator observer is derived using Lyapunov stability theory. The recognition rate of speed. By solving a bilinear matrix inequality, has been a constant adaptive observer gain...
This Paper discussed the principle of serial communication mainly, proposed the design method based on RS232, designed the hard circuit of serial communication, and realized the programming to PC Microcomputer and single chip microcomputer by using assembly language and C++ Builder separately.
The objective of this study is to evaluate the efficacy and safety of rhTNFR:Fc: a recombinant tumor necrosis factor receptor:Fc fusion protein compared with methotrexate (MTX) in patients with rheumatoid arthritis in China. We treated 238 patients with active rheumatoid arthritis with either twice weekly subcutaneous injection rhTNFR:Fc (25 mg) or weekly oral MTX (mean 15 mg per week) for 24 weeks...
Plasmacytoid dendritic cells (pDCs) can produce a large amount of interferon-alpha (IFN-α) upon exposure to TLR9 or TLR7 agonists. Human pDCs have been shown to play an important role in the pathogenesis of systemic lupus erythematosus (SLE) through increased production of IFN-α. So, how to negatively regulate activation of pDCs and how to evaluate the activation of pDC in SLE patients attract much...
