We present a quantum game with the restricted strategic space and its realization with linear optical system, which can be played by two players who are separated remotely. This game can also be realized on any other quantum computers. We find that the constraint brings some interesting properties that are useful for making game models.

A new method for the enzymatic synthesis of agmatine by immobilized Escherichia coli cells with arginine decarboxylase（ADC） activity was established and a series of optimal reaction conditions was set down. The arginine decarboxylase showed the maximum activity when the pyridoxal phosphate（PLP） concentration was 50 mmol/L, pH=7 and 45 °C. The arginine decarboxylase exhibited the maximum production efficiency when the substrate concentration was 100 mmol/L and the reaction time was 15 h. It was also observed that the appropriate concentration of Mg2＋, especially at 0.5 mmol/L promoted the arginine decarboxylase activity; Mn2＋ had little effect on the arginine decarboxylase activity. The inhibition of Cu2＋ and Zn2＋ to the arginine decarboxylase activity was significant. The immobilized cells were continuously used 6 times and the average conversion rate during the six-time usage was 55.6%. The immobilized cells exhibited favourable operational stability. After optimization, the maximally cumulative amount of agmatine could be up to 20 g/L. In addition, this method can also catalyze D,L-arginine to agmatine, leaving the pure optically D-arginine simultaneously. The method has a very important guiding significance to the enzymatic preparation of agmatine.

With the development of middleware technology, there are some new features to be adopted on demand in middleware platform based on container component. Aiming at the adaptation of middleware platform, from the nature of component container, this paper begins with behaviors features of EJB （Enterprise Java Bean） container, extracts general behaviors protocol of container, and defines its formal behaviors specification. In the end, the interactive relationship of components is described by WRIGHT language, and the configuration of whole system is shown. The method proposed in this paper mines the hidden features of framework of component container, and applies to refactor middleware platform in reflection and aspect-oriented programming technology.

With the east section of the Changji sag Zhunger Basin as a case study, both a principal curvature method and a moving least square method are elaborated. The moving least square method is introduced, for the first time, to fit a stratum surface. The results show that, using the same-degree base function, compared with a traditional least square method, the moving least square method can produce lower fitting errors, the fitting surface can describe the morphological characteristics of stratum surfaces more accurately and the principal curvature values vary within a wide range and may be more suitable for the prediction of the distribution of structural fractures. The moving least square method could be useful in curved surface fitting and stratum curvature analysis.

Heavy metal pollution in agricultural soils has serious negative influence on human health. Concentrations of Cd, Hg, As, Pb, Cr, Cu, Zn, and Ni in top soils （0-20 cm） of greenhouses and farmlands from four main vegetable production areas Shouguang, Laiyang, Jinxiang, and Zhangqiu in Shandong Province, one of the most rapidly developing regions in China, were measured in this study. Shouguang is mainly occupied by greenhouse vegetables and the other three areas are mainly open field culture. Total of 149 soil samples were collected. The average concentrations of the eight heavy metals of the tested 149 soil samples were all below the threshold values according to ＂Farmland environmental quality evaluation standards for edible agricultural products （HJ332-2006）＂ of China. However, most of the studied heavy metals were present at higher concentrations than those of the natural background levels in local agricultural soils. Among the total 149 soil samples, 22 samples were contaminated by Cd, Ni, Cu, or Hg. Comparisons showed that the main pollution element in greenhouse vegetable soils was Cd, while that of open field vegetable soils was Cu. The results of principal components analysis （PCA） suggested that concentrations of Cr, As, and Ni were mainly controlled by parent rocks; Hg and Pb were affected by anthropogenic activities such as vehicle and industrial fumes and waste water irrigation. Meanwhile, concentrations of Cd, Cu, and Zn were affected mainly by the use of agrochemicals. Most of the heavy metals were positively correlated with each other in concentration. Appropriate measures should be taken to effectively control heavy metal levels in vegetable soils and thus protect human health.

Background Tumor has an ability to become enriched in mesenchymal stem cells （MSCs） and of guiding MSCs to migrate to tumor tissue. But there are lack of relevant reports on the distribution and differentiation of MSCs in tumor tissue and the effect on tumor growth after MSCs engrafted in tumor tissue. In this study, we observed the distribution of bone marrow MSCs in tumor tissue and the possibility of MSCs differentiating into myofibroblast under the induction of local tumor microenvironment.Methods Twenty-four New Zealand rabbits were randomly classified into the control group and the test group. MSCs were isolated and cultured for each animal, vx-2 tumor tissue was transplanted under the bladder mucosa of each animal One week after the transplantation, the self F2 passage MSCs marked by 4＇,6-diamidino-2-phenylindole were transplanted into tumor tissue in the test group while only Dulbecco＇s modified Eagle＇s medium-low glucose was infused into the control group. Ultrasonography was performed for each animal 1, 2, 3 and 4 week（s） after the vx-2 tumor mass was transplanted. The maximum bladder tumor diameter of each animal was recorded and the mean value of each group was calculated. One animal from each group was sacrificed in the third week and the remaining animals in the fourth week to observe the tumor development. Another animal treated the same as the test group was sacrificed to observe the distribution of MSCs in tumor tissue one week after self MSCs transplantation. Immunofluorescence was used to trace MSCs in tumor tissue. The double labeling immunofluorescence for α-smooth muscle actin （α-SMA） and vimentin was performed to identify whether the MSCs can differentiate into myofibroblast.Results The ultrasonography showed no tumor mass one week after the vx-2 tumor mass transplantation. The mean maximum tumor diameter of the control group and test group was （0.70±0.14） cm and （0.78±0.14） cm, respectively, and there was no significant difference （t=1.30

基于Rankine公式,提出了一种可用于计算热轧薄壁槽钢柱抗火极限的方法,采用有限元软件***对模型进行非线性有限元分析,给出模型网格划分及其失效后的变形图。对比有限元分析结果与理论解,吻合较好。并针对薄壁槽钢柱的长细比、扭转刚度参数及截面的宽高比,对其抗火性能的影响进行参数分析。结果表明:长细比是影响柱子抗火能力的最重要的因素,长细比越大,极限抗火承载力越低;弹性弯扭屈曲向弯曲屈曲转化的临界长细比不随温度的改变而改变;对于薄壁槽钢柱而言,在截面面积一定或近似的情况下,截面宽高比越大,扭转刚度参数K越小,柱子在火灾下的极限承载力越好。
