To further improve the performance of constant modulus blind equalization, an instantaneous gradient change rate based dual mode blind equalization algorithm was proposed in this paper. The instantaneous gradient change rate is defined according to the change rate of weights between the adjacent equalization iteration before and after based on which the threshold was set, then the dual mode implement switch from constant modulus algorithm (CMA) to directed decision (DD) algorithm. Dual mode blind equalization algorithm can combine the advantage of robustness of CMA and the faster convergence rate of DD to improve the performance. Computer simulation results demonstrate the validity of the algorithm.

In order to obtain high β-glucosidase productivity from Aspergillus niger M85 fermentation broth, response surface methodology was applied to optimize the key fermentation parameters. Plackett - Burman design was firstly used to screen the significant factors influencing enzyme production, namely wheat bran and MgSO4?7H2O. concentration. The path of steepest ascent was further used to approach to the biggest response region of parameters affecting enzyme activity. The best results of combination experiments was wheat bran 17 g/L, and MgSO4?7H2O 8 g/L. Central composite design and response surface analysis were applied and a second-order regression equation model Y=-19.1057+0.4526X2+3.8260X5-0.02775X2X5-6.3569×10-3X22-0.2085X52 was established to predict enzyme acitivity level. The optimal fermentation parameters were as follows: wheat bran 18.345 g/L, and MgSO4?7H2O 7.963 g/L. After 4 days fermentation under the optimal conditions, the β- glucosidase activity reached 0.2640 U/mL, with an increase of 61.97% compared to the fermentation with original parameters. The prediction model indicated high reliability, which can be applied to optimization of β- glucosidase fermentation conditions. Enzyme production process show thatβ- glucosidase enzyme activity can achieve a maximum of 0.3334 U/mL within 5 days, while reducing sugars concentration decreased to 0.49 g/L.

We discuss the chaotic behavior of a kind of special map on an interval. The map is a good tool to approach problems in practice, such as digital signal processing and chaos control. To use the map for solving problems better, it is necessary to discuss its complexity. In addition, chaos is an useful concept in describing the complexity of a system. The best feature of chaotic system is that the evolution of the system is sensitive to initial conditions. Chaos in the sense of Li-Yorke and distributional chaos are relatively common. Through the method of construction and with the help of the distributional chaos for the shift on the one-sided symbolic space, we prove that the map is distributively chaotic , moreover, it is chaotic in the sense of Li-Yorke.

First of all, an exact relationship between tensile load and inner radius of sphere structure is obtained by using the incompressibility condition and the boundary conditions. Secondly, qualitative analyses are performed for solutions describing the finite deformation of the four sphere structures ( i.e. solid sphere, sphere with an initial micro-void, spherical shell, spherical membrane ). Finally, the effects of material parameters and structure parameters on radial deformation of sphere structures are discussed by utilizing numerical examples in detail.

The fate and potential effect of pharmaceuticals in the ecological environment have been paid high attention to in the world. The single toxicity of active pharmaceutical ingredients (APIs) of Aspirin, ciprofloxacin Hydrochloride and azithromycin were determined by applying the toxicity test to Photobacterium phosphoreum, and the primary ecological toxicity impact assessment results were obtained. Joint toxicity test for binary mixture and ternary mixture of three APIs were performed, their modes of joint action types were known juged by toxic unit method (TU), additive index method (AI) and mixed toxicity index (MTI). The results showed that, Aspirin had the highest single toxicity. The joint action mode of Aspirin and Ciprofloxacin with the highest joint toxicity were partly additive action, the other mixtures were antagonistic action. It can be shown from joint toxicity types that different inter-action can increase the healthy risk caused by pharmaceutical residual.

Loess collapsibility is not only the behavior arose from saturation or from zero suction. It is also affected by water content state (suction) obviously. Some evidences form laboratory tests and field observation indicate that in the constant vertical stress, the increase of water content or reduction of suction can cause loess collapse. Using the pressure plate extractor and GDS, soil water characteristic curves and coefficient of collapsibility of unsaturated loess are obtained, respectively. The paper analyses the influence of soil water characteristic curve of undisturbed loess collapsibility deformation. The results indicate some features of the gradual collapse behavior of the loess and its relationship with the form and parameters of soil-water characteristic curves.

First, the algorithm finds all convex polygons based on layered algorithm, secondly, inner convex polygons are inserted to outer convex polygon to get the blasting isochrones, and finally Greedy Algorithm is applied to fix a few net crosses of the isochrones. The results show that this algorithm can generate the blasting isochrones fast and solve the net crosses’ problem. Real blasting projects show the algorithm uses less time for the isochrones than theoretical testing. The isochrones algorithm is good for blasting network design in the blasting engineering.

Murahatibu, the punitive measures formed in the countryside of Japan in the Post-Edo era, is particularly analyzed in this article in terms of mentality, causes and its manifestations in the modern Japanese society. The formation of Murahatibu is closely related to the Japanese natural environment, Rice Cultivation Culture and Confucius Culture. The Rice Cultivation Culture exactly brings Japanese a Collective spirit, for frequent natural disasters makes the people cooperative and pull together to reduce the damage. Besides, the “Peace is the best option” ideology in the Confucius Culture really plays a great part in the formation of Murahatibu. Thus in their social life, Japanese people pay close attention to their accordance with the whole group and anyone who sacrifices the benefits of the group is undoubtedly excluded and regarded as humiliated. Nowadays in the society, the Murahatibu ideology is still deeply rooted in the Japanese mentality, though banned as punitive measures. Owing to this Shame Culture, Japanese people tend to remain their Murahatibu mentality spontaneously up till nowadays.

Singular nonlinear convex optimization problems have been received much attention in recent years. Most existing approaches are in the nature of iteration, which is time-consuming and ineffective. Different approaches to deal with such problems are promising. In this paper, a novel neural network model for solving singular nonlinear convex optimization problems is proposed. By using LaSalle's invariance principle, it is shown that the proposed network is globally convergent which guarantees the effectiveness of the proposed model for solving singular nonlinear optimization problems. Numerical simulation further verified the effectiveness of the proposed neural network model.

6-OH of ?-Cyclodextrin was modified by diethylene triamine, 6-deoxy-diethylene triamido-?-Cyclodextrin(DTCD) was prepared, which complexes 1,5-naphthalenediamine and 1,8-naphthalenediamine, respectively, in the presence of lanthanide NdCl3 to synthesize two ternary inclusion complexes(host-guest-metal). The molecular recognition of DTCD-Nd complex to 1,5-naphthalenediamine and 1,8-naphthalenediamine was investigated via 1H NMR spectroscopy. The stoichiometric proportion of host and guest molecules is 2:1 for the complexes. Signal degeneration still exists for the guest molecules after the inclusion process, revealing the symmetrical conformation of the guest molecules inside the cavities of the two host molecules. Two complexes both exhibit “sandwich”-typed structure.
