Chitosanases are lytic enzymes involved in the degradation of chitosan, a component of fungal cell walls. The phytopathogenic fungus Fusarium solani produces an extracellular chitosanase, CSN1, the role of which in the physiology and virulence of the fungus remains to be expounded. Here, we studied the expression of the CSN1 gene through gene silencing and(More)
Based on application practices of the CampusWAMS developed in Western Japan 60-Hz power system and Thailand power system, this paper presents a single-mode-oriented monitoring and estimation scheme of power system small-signal stability. The data filtering technique based on FFT is employed to extract oscillation data for single mode. The auto spectrum(More)
We examined the relationship between an early spontaneous type V blood pressure fluctuation and the post-thrombolysis prognosis of patients with acute cerebral infarction. Patients were admitted consecutively. All patients were categorized into the type V blood pressure fluctuation group or non-type V blood pressure group. Their blood pressure was monitored(More)
Real-time transient stability status prediction (RTSSP) is very important to maintain the safety and stability of electrical power systems, where any unstable contingency will be likely to cause large-scale blackout. Most of machine learning methods used for RTSSP attempt to attain a low classification error, which implies that the misclassification costs(More)
OBJECTIVE To investigate the risk factors for hemorrhagic transformation (HT) after intravenous thrombolysis using a recombinant tissue plasminogen activator (r-tPA) in acute cerebral infarction. METHODS Patients with acute cerebral infarction receiving r-tPA thrombolysis in Shanghai Eastern Hospital were retrospectively studied. Based on the cranial(More)
