A novel adaptive dual network design consisting of a rough adjustment network (RAN) and a fine adjustment network (FAN) is proposed to eliminate the unknown time-variant uncertainties of servo system. To accomplish this objective, a RAN is proposed based on the combination of sliding mode control, function approximation, and error compensation technique.(More)
Metabolomics, the systematic analysis of potential metabolites in a biological specimen, has been increasingly applied to discovering biomarkers, identifying perturbed pathways, measuring therapeutic targets, and discovering new drugs. By analyzing and verifying the significant difference in metabolic profiles and changes of metabolite biomarkers,(More)
Network always suffers from the traffic anomaly such as router rate change, device restart or the worm attack. The early detection of unusual anomaly in the network is a key to fast recover and avoidance of future serious problem to provide a stable network transmission. In this paper we present a statistical approach to analysis the distribution of network(More)
Rhizosphere oxygen profiles are the key to understanding the role of wetland plants in ecological remediation. Though in situ determination of the rhizosphere oxygen profiles has been performed occasionally at certain growing stages within days, comprehensive study on individual roots during weeks is still missing. Seedlings of Acorus calamus, a wetland(More)
OBJECTIVE To approach the central nervous mechanism of abdominal acupuncture by using resting-state functional magnetic resonance imaging (fMRI). METHODS Twelve old healthy volunteers were treated by standardized abdominal acupuncture with invigorating the kidney and nourishing marrow method and Zhongwan (CV 12), Xiawan (CV 10), Qihai (CV 6), Guanyuan (CV(More)
Theasymmetric unit of the title salt, C19H17N2S(+)·Cl(-)·0.75H2O, contains two symmetrically independent formula units of the carbenium salt along with three water mol-ecules. The water mol-ecules are only 50% occupated, and one of them is positioned in a hydro-phobic pocket not forming any hydrogen bonds. The conformation of the independent cations is very(More)
