It is a syndrome with many different causes. We reviewed the clinical, electrophysi- ological and nerve biopsy findings of 14 patients who suffered from multiple mononeuropathy in our clinic between January 2009 and June 2013. Patients were diagnosed with vasculitic neurop- athy （n = 6）, perineuritis （n = 2）, chronic inflammatory demyelinating polyradiculoneuropathy （n = 2） or Lewis-Sumner syndrome （n = 1） on the basis of clinical features, laboratory data, elec- trophysiological investigations and nerve biopsies. Two patients who were clinically diagnosed with vasculitic neuropathy and one patient who was clinically diagnosed with chronic inflamma- tory demyelinating polyradiculoneuropathy were not confirmed by nerve biopsy. Nerve biopsies confirmed clinical diagnosis in 78.6% of the patients （11/14）. Nerve biopsy pathological diagno- sis is crucial to the etiological diagnosis of multiple mononeuropathy.展开更多

From the simulation using the ＂PSCAD/EMTDC＂ code, it is found that these control methods can drastically reduce the reac- tive power induced by the four units of the ＂Booster PS＂. In addition, the voltage fluctuation of the motor-generator connected to the ＂Booster PS＂ is expected to be suppressed. This can also contribute to achieve stable control of the JT-60SA magnet power supplies.展开更多
