In the study of customized bus planning for non-real-time response, the network planning of passenger direct-arrival of single-origin-destination and single-type is emphasized, while the development of diversified line operation mode is often neglected. Based on the planning theory of conventional bus, the Vehicle Routing Problem(VRP)is referred and the operated characteristics of customized bus are combined. Then this paper constructs the network design model of customized bus in diversified operation of multi-origin-destination and multi-type vehicle and passengers mixed load. Besides, the genetic algorithm is applied to improve the coding rules and to solve the multi-objective combinatorial optimization problem. Finally, an example is used to analyze the method. Compared with the conventional bus, the average stop number is reduced, the full-road ratio is increased, the average travel time is shortened, and the average travel speed is improved. The result shows that the model can get the ideal line operation schemes. The research results enrich the operation mode of customized bus. In the expansion of passenger travel demand coverage, the new method increases the flexibility of the vehicle deployment and line integration. At last, the research can effectively improve the demand response of passengers and the enterprises’ benefit.

In order to improve the effectiveness and accuracy of the control system and to solve the shortcomings such as too many parameters and failing to update the tuning of these control parameters timely of the nonlinear active disturbance rejection control, this paper puts forward a kind of attitude stability control method of the combination of seeker optimization algorithm with inertia term and active disturbance rejection control.

State-of-charge (SOC) is a very important part of lithium-ion battery prediction and health management. As the SOC of the lithium battery cannot be measured directly, this paper presents a method of estimating the SOC of the lithium-ion battery by the random forest regression. Firstly, a random forest regression model is constructed. The battery current, battery voltage and battery temperature are used as the training input of the model, and the corresponding SOC is used as the training output of the model. And then, the random forest algorithm for model training is conducted. Finally, the training model is applied to the battery SOC estimation. The results show that by the random forest regression algorithm, the maximum estimation error of the lithium-ion battery charge is 0.02,and the RMSE is 0.003204.This method can effectively estimate the lithium-ion battery SOC and has high estimation accuracy. This model may provide a reference for the model construction of future battery charge estimation system.

To address the problem that the tracker is easy to drift away from the target and even failure in complex scenes, this paper presents an infrared-visible target tracking algorithm based on AdaBoost confidence map. Firstly, the target samples and background samples in infrared-visible images are characterized by using color and texture descriptor and are classified using AdaBoost classifier, and then the confidence maps of infrared and visible images are calculated based on the classification scores. Secondly, the similarity between confidence maps of target candidate and its template is calculated for visible and infrared images, and the visible similarity and infrared similarity are integrated into a joint objective function by weighting. Finally, a joint target location-shift formula is induced by performing multi-variable Taylor series expansion and maximization on the objective function, and the optimal target location is gained recursively by applying the mean shift procedure. The experimental result in infrared-visible image sequences demonstrates that the proposed method performs well in dealing with illumination change, target intersection, target occlusion and so on.

With the development of Web 2.0 technology, the social network has provided a new and convenient platform to communicate and collaborate for people. Faced with the problem of network information overloaded, it is very difficult to find the experts who are interested in the topic and are reliable to make decisions based on experts’ opinions. In this paper, domain experts recommendation in social network based on the LDA theme model of trust method is proposed. The personalized recommendation of domain experts for the user trust is implemented. The method is based on the topic model (LDA), the social network structure, the users’ trust relationship and social influence. It makes up the deficiency of the traditional experts recommendation methods that only involve expert’s characteristics which lead to low recommendation accuracy and the problem of the pattern of recommended results. Finally, the feasibility and effectiveness of the method are verified by experiments.

In this paper, under some assumptions of V, K and f, the following nonlinear Schrödinger-Maxwell equations are studied.
-Δu+V(x)u+K(x)φu=f(x,u), in R³,
-Δφ=K(x)u², in R³.
First, the nontrivial solution of Schrödinger-Maxwell equations is obtained by using mountain pass theorem. Then, it is shown that the functional is achieved on Nehari manifold, and finally, ground state solutions of Schrödinger-Maxwell equations are obtained. Some conditions in previous literatures are weakened and the conclusions of high energy solutions in previous references are generalized in this paper.

In this paper, the ARMA-GARCH-t model is employed to forecast daily return and volatility of the three stocks with a high market value in different industries of Shanghai Stock Exchange. Under the framework of extended Black-Litterman (BL) model, investor’s subjective return distributions are combined with asset’s priori balanced distribution. Then the weights of the asset allocation is calculated and compared with the ones from traditional Markowitz mean-variance (MV) investment portfolio. The empirical results show that the BL model puts more weight to the asset with high investor’s confidence level and the return of portfolio is larger than the MV case. Finally, the analysis results of the margin trading are applied to verify the validity of the market allocation of the three stocks, which confirms the conclusion that the BL model is more in line with investor expectations. The study can provide more reference for asset managers and investors in asset allocation.

Meanwhile, the removal rate of NH₃-N reached to 65%-75%, 40%-55%, respectively in the total system and ABR. The content of dehydrogenase and protease in each compartment of ABR gradually decreased, and the content of dehydrogenase and protease was 41.06 mg/(g·h) and 0.42 mg/g in the first compartment of the ABR, respectively. According to the high-throughput sequencing results, Chloroflexi, Firmicutes, Proteobacteria were dominant bacteria in the ABR sludge in particular, the abundance of Chloroflexi was 51.12%,46.96%,62.44% and 47.23% in each compartment. Chloroflexi is beneficial to the degradation of a series of complex pollutants. At the same time, known from the heatmap figure, the microbial community structures in the fourth compartment and the first compartment were much closer due to the existence of reflux.

In this study, Cu、Zn、Pb、Cr、Ni、Cd and As were analyzed in the soil samples and they were collected on the highways from the west entrance to the top of the south of Wutai Mountain in different elevations and different soil layers. Two indices—the Index of Geoaccumulation and the Potential Ecological Risk Index were used to evaluate the degree of pollution by heavy metals. The results indicated that the soils in study area were characterized by on-to-partial moderate pollution and posed a high potential ecological risk. With the altitude increasing, the degree pollution and the potential ecological risk increased. The degree pollution and the potential ecological risk in the 0-10 cm layer were higher than that in 10-20 cm layer. The potential ecological risk was characterized by the order of Cd>As>Cu>Ni>Cr>Pb>Zn with the increase of altitude, which belonged to the level of “high ecological risk” on the whole. The potential comprehensive ecological risk level of 0-10 cm and 10-20 cm soil layers is “the highest ecological risk” and “higher ecological risk” respectively with the predominant risk factor being Cd.

The immobilization of lipase from procine pancrestic was performed by using domestic epoxy resin LXEP-120. The immobilization conditions were optimized, and the enzymatic properties of immobilized lipase and free lipase were also compared. The optimal immobilization conditions were as follows: using 1.0 mol/L pH6.0 potassium phosphate buffer, the quantity of epoxy resin being 5.0 g, the appropriate temperature being 22 ℃, and the immobilized time being 12 h. Under above optimized conditions, the activity of immobilized lipase was about 400 U/g, and the recovery rate of the enzymatic activity of the immobilized lipase reached 92.79%. The immobilized lipase retained 70% of its initial enzymatic activity after repeated usage for 10 times. The optimal reaction pH (pH 8.0) was the same as that of free lipase, and the optimal reaction temperature(45 ℃) was 5 ℃ higher than that of free lipase. The thermal-stability and operating-stability reuse rate of immobilized lipase were significantly better than those of free lipase. Additionally, immobilized lipase exhibited very good storage stability. The study shows that domestic epoxy resins LXEP-120 possesses great potential in the immobilization of industrial enzymes.

P. fanjingshan sp. nov. is similar to P. cavaleriei (Schenkel, 1963), but differs from the latter by the strong embolus and the wide RTA. T. zhui sp. nov. can be easily distinguished from other Trachelas species by the large copulatory openings of the epigyne. Type specimens are deposited in the School of Life Science, Southwest University, Chongqing, China.

To evaluate the neuroprotective effect of Magnesium-L-threonate (MgT) on mice model of Parkinson’s disease (PD) induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP) and to investigate the possible mechanism.The PD mice model was established. The mice were randomly divided into control group, MPTP group and the MPTP+MgT group. Rotary bar method was used to observe behavioral changes in mice. The number of dopaminergic neurons in substantia nigra was observed by TH staining. The expression of GFAP, iNOS and TH in substantia nigra and striatum were detected by Western blotting.The time for the MPTP+MgT group to stay on the rotating rod was 68.07% longer than that in the MPTP group. The results showed that, in MPTP+MgT group, the number of dopamine neurons in the substantia nigra increased by 46.15% than that in the MPTP group. Compared with MPTP group, the expression of GFAP and iNOS in MPTP+MgT group was statistically significant (P<0.05).The mechanism of MgT neuroprotective effect is probably related to the down-regulation of GFAP and iNOS expression,and inhibition of inflammation and oxidative stress.
