Different from the discriminatory analysis method currently used in the mathemalic statistics, it is unnecessary to assume that the predictand should be subject to a certain distribution. On the contrary, the statistical relationship between predictand and predictor has been obtained directly with computer according to actual distribution to recognize the category of patterns. Result of forecast has been improved as compared with the usual analytic discriminatory method. The influence of predictor on predictand can be seen clearly from this method and the transparency is good. Therefore, it is better to use the method in very short range forecast for which causality is more obvious.展开更多

The results show that EA performed at Chen Time could improve the left ventricular function of CHD patients as indicated by shortening of PEPI and decrease of PEPI/LVETI ratio; on the contrary, EA performed at Xu Time prolonged PEPI and raised PEPI/LVETI ratio in CHD patients, suggesting impairment of left ventricular function.展开更多

In the present study, the Kunming white mouse was used as an animal model and indirect immunofluorescence was performed to analyze the toxic effects of alcohol on early pre-implantation embryos. H3K9 acetylation immunofluorescence could not be detected in MII oocytes. H3K9 acetylation levels in the treatment group were higher than in the control group during the morula stage, and contrary to results during the blastocyst stage. Other stages showed no obvious differences for in vivo embryos. For in vitro embryos, almost no difference was found between the two experimental groups across all stages, and both groups showed increasing H3K9 acetylation levels（except at the 2-cell stage）. This study shows that H3K9 acetylation levels in early pre-implantation embryos are notably impacted by excessive alcohol ingestion by females. These data are the first step in understanding the epigenetic mechanism of alcohol toxicity in early preimplantation mouse embryos.展开更多

The influence of the performance of the carbon fiber reinforced plastic (CFRP) molds made by subjects with difference skill level was discussed. Subjects were allowed to choose their process and molding tools. Subject A had 13 years,and subject B had 1 year of professional experience.The time spent usage of tools and process was recorded by a video camera used for analysis and comparison. Mechanical properties assessed in this study include tensile,compressive and Izod impact properties. The working time analysis shows that subject A needs short time for each process. On the other hand,subject B takes twice time to work for each process compared with subject A. From the surface and cross-section observation, it was found that the molding made by subject B had wrinkles all over and the disorderly inter-layer direction; on the contrary,the wrinkles on the molding surface of subject A are barely,and the inter-layer direction of which are more orderly. The results of tensile and Izod impact tests show that the surface winkles have little influence on the mechanical properties of the molding. According to the compression test and failure structure analysis in edge corner part,it was found that it had a great influence on the compression mechanical properties of the sample belonging to different subjects with different experience.展开更多
