Hand-foot-mouth disease is an infectious disease caused by a variety of enterovirus. The enterovirus 7l is the main pathogen of Hand-foot-mouth disease. The main symptoms are the rash or herpes of hand, foot, mouth, buttocks and other parts, bringing aseptic meningitis, brainstem encephalitis and acute flaccid paralysis and other serious neurological complications and pulmonary edema, pulmonary hemorrhage. Hand-foot-mouth disease harms seriously children's health. Currently, the overall treatment of severe Hand-foot-mouth disease adopts the symptomatic therapy. Early identification of severe and early intervention are the keys to the treatment of children with Hand-foot-mouth disease.

AbstractBased on four sets of numerical simulations prescribed with atmospheric radiative forcing and sea surface temperature (SST) forcing in the Community Atmospheric Model version 3 (CAM3), the interannual and interdecadal variabilities of the Antarctic oscillation (AAO) during austral summer were studied. It was found that the interannual variability is mainly driven by SST forcing. On the other hand, atmospheric radiative forcing plays a major role in the interdecadal variability. A cooling trend was found in the high latitudes of the Southern Hemisphere (SH) when atmospheric radiative forcing was specified in the model. This cooling trend tended to enhance the temperature gradient between the mid and high latitudes in the SH, inducing a transition of the AAO from a negative to a positive phase on the interdecadal timescale. The cooling trend was also partly weakened by the SST forcing, leading to a better simulation compared with the purely atmospheric radiative forcing run. Therefore, SST forcing cannot be ignored, although it is not as important as atmospheric radiative forcing.

The paper reports results of investigation on the harmonic detection technique of a complicated power supply system such as an AC excited generation system, which has a variable fundamental frequency and low order harmonics with rich sub-harmonics whose frequencies are lower than the fundamental one. The in-phase correlation filtering technique, based on the frequency shifting principle, is proposed in this paper. Theoretical analysis and experimental results validate the effectiveness of this technique for the harmonic detections of AC excited generation systems.
