Two-photon four-dimensional spatial modes partially entangled Dicke state can be compactly generated from six concurrent spontaneous parametric down-conversion processes by cascading poling domain structures in 5% MgO-doped poled lithium niobate bulk crystal. Entanglement concentration of the two-photon four-dimensional spatial modes partially entangled Dicke state can be realized by using quantum nondestructive detection of nonlinear Kerr medium, optical beam splitter, and quantum gate operation. © 2017, Springer Science+Business Media New York.

Scale effect is one of the basic aspects of urban compactness. This paper takes the use of urban construction land as the breakthrough point, continuity degree and Gini coefficient as the indexes to analyse the scale effect of grid from the calculation through the different scales grid analysis of urban construction land extracted by ERDAS and ARCGIS respectively. The result showed that the selected indicators quantitively indicate the features of research area land, different scale effects of two indexes, big difference in continuity degree influenced by scale, and slight impact on Gini coefficient influenced by scale. © Published under licence by IOP Publishing Ltd.

In this paper, we propose and investigate a stochastic two-prey one-predator model. Firstly, under some simple assumptions, we show that for each species x i, i=1,2,3, there is a π i which is represented by the coefficients of the model. If π i <1, then x i goes to extinction (i.e., lim t→+∞ x i (t)=0); if π i >1, then x i is stable in the mean (i.e., limt→+∞t-1 ∫0 txi(s), ds=a positive constant). Secondly, we prove that there is a stationary distribution to this model and it has the ergodic property. Thirdly, we establish the sufficient conditions for global asymptotic stability of the positive solution. Finally, we introduce some numerical simulations to illustrate the theoretical results. © 2013 Springer Science+Business Media New York.


The electrochemical reduction of sunset yellow at a multiwalled carbon nanotube (MWCNT)-modified glassy carbon electrode is investigated using cyclic voltammetry. A simple, sensitive, and inexpensive method for determination of sunset yellow in soft drinks is proposed and the accuracy and reproducibility of this determination method are evaluated. This method is satisfactorily applied for the determination of sunset yellow in soft drinks in the concentration range of 1.2-125.0 mg L -1 and 125.0-265.0 mg L -1, with a detection limit of 0.5 mg L -1.

Since Einstein predicted the phenomenon of Bose-Einstein Condensation in 1924, more physical scientists have tried to realize it, but they didn't break through until 1995. In this paper, the characteristics and conditions of BEC are introduced first, and then the exploration course is presented. Based on these studied, the realizing techniques of BEC is proposed, including Laser Refrigeration Technique, Ion Trapping of Magnetic Capture, Evaporative Cooling Technology and Measurement Technology of BEC, etc. © (2010) Trans Tech Publications.

Recently Liu et al. (EPL, 87 (2009) 30006) have proposed two new schemes for probabilistically preparing arbitrary two- and three-qubit states with complex coefficients based on two- and three-qubit projective measurement, respectively. In this letter, we present a possible improvement of the successful probability for their schemes. For this purpose, we put forward two novel schemes for remote preparation of arbitrary two- and three-qubit states with complex coefficients via two and three GHZ states as the quantum channel, respectively. To complete the schemes, two novel unitary operations have been introduced. Compared with the previous schemes, the advantage of our schemes is that the total successful probability can reach 100%.

The electrochemical reduction of C.I. Acid Red 18 on the surface of multi-walled carbon nanotube-modified glassy carbon electrode was investigated using cyclic voltammetry. A novel, simple, sensitive and inexpensive method for determination of C.I. Acid Red 18 in soft drinks was proposed and the accuracy and reproducibility of this determination method were evaluated. The method was satisfactorily applied for the determination of C.I.

This paper presents a method used to the eddy current sensor modeling based on Lagurre orthogonal polynomial basis functions neural network. The principle and algorithms of weight values of neural network are introduced. In this method, the non-linear model is set up by Lagurre orthogonal polynomial basis functions neural network according to measurement data. The results show that the sensor modeling has the character of strong robustness and on-line modeling compared with the sensor modeling of least square method. The maximum nonlinearity error can be reduced to 0.048% by using polynomial basis functions neural network. However, the maximum nonlinearity error is 0.075% using the least square method.

This note is concerned with the optimal harvesting of a stochastic logistic model with time delay. The classical optimal harvesting question of this type of model is difficult because it is very difficult to obtain the explicit solution of the corresponding delay Fokker–Planck equation. The main aim of this note was to find a new approach to overcome this problem. In this note, using the ergodic method, sufficient and necessary criteria for the existence of optimal harvesting policy of our model are obtained. At the same time, the optimal harvesting effort and the maximum of harvesting yield are given. This method provides a new approach to study the optimal harvesting problem of stochastic population models, which can be also applied to investigate stochastic multi-species models. © 2015, Springer Science+Business Media New York.
