    This paper deals with a Dirichlet boundary value problem for a three-species cooperating model with porous medium type of diffusion.It is proved that the time-dependent problem possesses a unique bounded global solution under appropriate conditions;and in addition to the trivial and semi-trivial solutions,there exists a positive maximal solution and a positive minimal solution to the corresponding steady state problem.Moreover,the time-dependent solution converges to the maximal solution for one class of initial functions,and to the minimal solution for another class of initial functions.The above convergence property holds true for any reaction rates in the reaction function.The results indicate that the dynamic behavior of a cooperating model with porous medium type of diffusion can be quite different from the model with constant diffusion terms.

    In this paper,we disscuss a class of generalized variational inequality problems involved in strictly pseudo-contractive mapping in Banach spaces by using some new algorithms which couple modified extra-gradient method with extended Mann iteration.It is proved that the sequences generated by the proposed iterative algorithms converge strongly to the solution of the generalized variational inequality problem.The results presented in this paper extend and improve some well-known results in the literature.

    The visualization study of the period of bubble behavior in the microgroove heat sinks was implemented by high speed photography technique.The microgroove plates were vertically placed and coated with 250 nm titanium nano coating to generate micro-nano composite structure surface.The results showed that when the heat flux density was small,the bubble period decreased with the increase of micro groove depth-width ratio;with the increase of heat flux density,bubble period decreased,and the micro-scale effect on bubble period was weaken as well.

    Prediction models of neural network and partial least squares for wheat scab are proposed,which provides a scientific basis for prevention of wheat scab.The meteorological factors and morbidity rate between 2004 and 2014 in Anhui are chosen as independent variables and dependent variable,respectively.The alternating gradient back-propagation algorithm of Flecher-Reeves is employed to build the neural network model.Since the simple functional relationship between meteorological factors and morbidity rate can't be provided by the model,the correlation among meteorological factors is analyzed and the partial least squares model is built through principal component analysis and regression analysis.The accuracy of the neural network model is about 99%,through which the topology between meteorological factors and morbidity rate is provided.The linear function is obtained through the partial least squares model and the accuracy is about 97%.Both the neural network model and the partial least squares model can achieve high prediction accuracy and provide scientific guidance for the prevention of Anhui wheat scab.

    From 2009 to 2013,the values of stature and body mass of 16 501 rural Chinese Han adults from 36 regions were measured through the stratified random sampling method,including eleven Chinese dialect groups in north,middle and south China.The BMI values were calculated according to the values of stature and body mass,and were compared with those of Japanese and Korean.Results show that the BMI values of the dialect groups of Wu,Min and Hakka in China were close to those of Japanese,while the BMI values of the other eight groups in China were different from those of Japanese.The BMI values of northwest,southwest and Jianghuai dialect groups were similar to those of Korean,while the BMI values of the other eight groups were different from those of Korean.Among the Han groups with different BIM values from those of Japanese and Korean,north groups generally had larger BIM values,while south groups had smaller BIM values than those of Japanese and Korean.

    In order to obtain high-temperature resistant cellulose-degrading bacteria,samples were collected from chicken manure and mushroom residue compost.After being enriched through filter paper medium,high-temperature resistant cellulose-degrading bacteria were isolated and purified on cellulose Congo red medium.The isolates were preliminarily screened through filter medium and cellulose Congo red medium,and then were further screened through quantitative analysis of cellulase activity of liquid fermentation broth.A high-temperature resistant cellulose-degrading bacterium,designated strain XD-3,was obtained,which grew well at 50 ℃ and the carboxymethyl-cellulase (CMCase) activity was 6.14±0.37 U/mL.The combination of morphology,physiological/biochemical characterization and phylogenetic analysis based on 16S rRNA gene sequence showed that strain XD-3 was a member of a known Bacillus species,Bacillus amyloliquefaciens.

    A mechanic seismic analysis model is constructed with the pseudo-classic three-storey Chinese-style attic as the study object.Applying the artificial wave and the natural wave to the structure,we obtain the storey displacement in X direction and Y direction through time-procedure analysis.The research shows that the displacement in X direction is smaller than that in Y direction,which indicates that the lateral stiffness in X direction is larger than that in Y direction.The 1-3 storey displacement angle is far less than the elasticity limit 1/550,which indicates that the structural stiffness is large.Reduction in the cross-sectional areas of walls and pillar and reduction in the number of beams and pillars have little effect on the structural mechanic performance.To increase the integral stiffness,it is necessary to increase the lateral stiffness in Y direction which can be realized through increasing the cross-section area in Y direction.
