With the goal of achieving advanced and multi-step prediction of silicon content of molten iron in the blast furnace ironmaking process,a path adaptive optimization seeking strategy coupled with simulated annealing algorithm and genetic algorithm was proposed from the perspective of innovative intelligent algorithm *** was further coupled with wavelet neural network algorithm to deeply explore the nonlinear and strong coupling relationship between the information of big data samples and construct a cascade model for continuous prediction of silicon content of molten iron with the intelligent research results of state variables such as permeability index as the node and silicon content forecast as the *** the model construction process,the 3r criterion was used for non-anomaly estimation of abnormal data to build a time-aligned sample set for multi-step forecasting of iron content,the normalization method was used to eliminate the influence of dimensionality of sample information,and the spearman correlation analysis algorithm was used to eliminate the time delay between state variables,control variables,and silicon content of molten iron in the blast furnace smelting *** results show that permeability and theoretical combustion temperature as the key state variable nodes have real-time correlation with the silicon content of molten iron,and there are accurate forecasting results on the optimal path with the endpoint of molten iron silicon content *** path finding based on the improved genetic algorithm of simulated annealing has good effect on the downscaling and depth characterization of sample data and improves the data ecology for the application of wavelet neural network *** accuracy of the real-time continuous forecasting model for the silicon content of molten iron reaches 95.24%;the hit rate of continuous forecasting one step ahead reaches 91.16%,and the hit rate of continuous forecasting five steps ahead is 87.41

We investigate the heterotic super-Liouville model on the base of the basic Lie super-algebra Osp(1|2).Using the super extension of Leznov-Saveliev analysis and Drinfeld Sokolov linear system, we construct the explicit solution of the heterotic super-Liouville system in component form. We also show that the solutions are local and periodic by calculating the exchange relation of the solution. Finally starting from the action of heterotic super-Liou ville model, we obtain the conserved current and conserved charge which possessed the BR ST properties.

Objective To investigate the mechanisms underlying elemene-induced analgesia in rats with spared nerve injury(SNI).Methods Sixty-five rats were equally divided into 5 groups using a random number table:naive group,sham group,SNI group,SNI+elemene(40 mg·kg−1·d−1)group and naive+elemene(40 mg·kg−1·d−1)*** SNI rat model was established and the intervention were given respectively for 14 consecutive *** Frey filament tests and elevated plus-maze(EPM)tests were used to evaluate the effect of elemene on the mechanical threshold and anxiety,*** and immunostaining were used to measure the expression of glial fibrillary acidic protein(GFAP)and NMYC downstream-regulated gene 2(NDRG2)within the lumbar spinal dorsal horn(SDH).Results The SNI rat model exhibited a significant decrease in paw withdrawal threshold and exploratory behaviour in the EPM(P<0.05).Consecutive administration of elemene alleviated SNI-induced mechanical allodynia and anxiety in rats(P<0.05).Immunohistochemical data showed that elemene decreased SNI-induced upregulation of NDRG2 within the SDH(P<0.05).Double immunofluorescent staining data further showed that elemene decreased SNI-induced upregulation of the number of GFAP immunoreactive(-ir),NDRG-ir,and GFAP/NDRG2 double-labelled cells within the SDH(P<0.05).Immunoblotting data showed that elemene decreased SNI-induced upregulation of GFAP and NDRG2 within the SDH(P<0.05).Conclusion Elemene possibly alleviated neuropathic pain by downregulating the expression of NDRG2 in spinal astrocytes in a rat model of SNI.

Distinguishability plays a crucial rule in studying observability of hybrid system such as switched system. Recently, for two linear systems, Lou and Si gave a condition not only necessary but also sufficient to the distinguishability of linear systems. However, the condition is not easy enough to verify. This paper will give a new equivalent condition which is relatively easy to verify.
