LMCPs(1.0 g/kg body weight) in 15% ethanol(10 mL/kg body weight) were given to Wister rats by intragastric gavage. The assay of blood ethanol was conducted by using the enzyme based assay kit. The amino acid analysis was made with an amino acid analyzer. The data of the animal experiments showed that LMCPs could accelerate the metabolism of alcohol in rats. In the control group, the blood ethanol concentration reached the maximum level of (827.0±77.3) mg/L after ethanol loading for 30 min, then gradually decreased. In contrast, the blood ethanol concentration only reached (527.25±47.0) mg/L after 30 min in the group of LMCPs taken. These results indicate that LMCPs could decrease ethanol concentration in blood rapidly.展开更多

Different from conventional artificial neural network, the KⅢnetwork works in its chaotic trajectory. It can simulate not only the output EEG waveform observed in electrophysiological experiments, but also the biological intelligence for pattern classification. The simulation analysis and application to the recognition of handwriting numerals are presented here. The classification performance of the KⅢnetwork at different noise levels was also investigated.展开更多

Calculated carbon flux distribution for the interval from 1981 to 1997 confirms the existence of a terrestrial carbon sink in mid-high latitude area of North Hemisphere. Strong interannual variability exists in carbon flux patterns, implying a possible link with ENSO and other natural episodes such as Pinatubo volcano eruption in 1991. Mechanism of this possible link was investigated with statistic method. Correlation analysis indicated that in North Hemisphere, climatic factors such as temperature and precipitation, to some extend, could influence the carbon cycle process of land and ocean, thus cause considerable change in carbon flux distribution. In addition, correlation study also demonstrated the possible important role of Asian terrestrial ecosystems in carbon cycle.展开更多

Comprehensive budget management can significantly improve the management level of the enterprise, enhance the economic benefits of the enterprise, realize the strategic objectives of the enterprise and enhance the competitive advantage. Especially after entering the new economic normal, enterprises need to face a more complex operating environment. It is of great significance for enterprises to establish a comprehensive budget management mechanism for their long-term and stable development.展开更多

It aims to move dynamic computation within the network. Mobile agent technology is a novel paradigm for distributed computation. This paper discusses the applicability of mobile agent technology for the development of active networks, both security policy and resource management, and other expected application as well. Based on the discussion, it describes a general mobile agent based Active Network (AN) architecture at last.展开更多
