A number of studies have focused on the effects of rare earth elements(REEs) on crop plants,while little attention has been paid on how tolerant plant species respond to increasing mixed REE *** this study,ramie(Boehmeria nivea L.) was exposed to a series of REE concentrations prepared with equimolar mixtures of 16 REEs(i.e.0,1.6,8,16,80,160,400,800 μmol/L) in order to explore REE accumulation and fractionation characteristics in ramie and the responses of this plant to mixed *** show that ramie root and shoot biomasses are unaffected under lower REE concentrations(1.6-80 μmol/L),while the growth of ramie and the uptake of nutrients especially Ca and Mn are largely inhibited under higher REE concentrations(160-800 μmol/L).The P and Mo concentrations in the roots increase with the increasing REE concentrations in the solution,suggestive of an involvement of P and Mo in dealing with the high concentrations of REEs in this *** preferential uptake of Ce and heavy REEs(HREEs) and the preferential transport of HREEs within the plant lead to a positive Ce anomaly and a HREE enrichment in ramie *** study suggests that ramie could be a good candidate for the phyto re mediation of heavily REE-contaminated soils(e.g.,REE mine tailings in southern China).Our results also shed light on points of taking into account phytoremediation management strategies of REEcontaminated soils(e.g.,P and Mo fertilization).

Inhibition of protein synthesis appeared to be a direet toxic effect of podophyllotoxin and occurred independently from that of RNA. The reduction of DNA synthesis was reflected by a reduction of H3-thymidine incorporation,which is believed to be the consequence of inhibition on the mitotic activity by podophyllotoxin

Factors Influencing FDI Location Choice in China's Inland Areas

China & world Economy 2008年第2期16卷 93-108页

作者： Laijun Luo louis Brennan chang Liu Yuze Luo Assistant Professor School of Economics Renmin University Beijing China Senior Lecturer School of Business Trinity College Dublin Ireland PhD candidate School of Business Trinity College Dublin Ireland Researcher China Academy of Telecom Research Ministry of Information Industry Beijing China

Since 1978, the bulk of foreign direct investment （FDI） has gone to the south-eastern coastal areas in China, with only a small portion received inland. with the launch of the western Development Strategy in 2000 and the Central China Rising Strategy in 2004, the choice of investment locations has expanded to inland areas. Based on panel data covering 98 inland cities from 1999 to 2005, this study identifies location preference variables for FDI invested in China＇s inland areas, and finds that well-established factors such as natural resources and low labor costs are not important factors in determining FDI locations within China＇s inland. Instead, policy incentives and industrial agglomeration are the most important factors. The findings of the present study have policy implications for both host country authorities and multinational corporations.

在智能交通控制系统、军事数字化战场、辅助驾驶系统中,实时、精确、可靠的移动对象不确定性轨迹预测具有极高的应用价值.智能轨迹预测不仅可以提供精准的基于位置的服务,而且可以提前监测和预判交通状况,进而推荐最佳路线,已经成为移动对象数据库研究的热点,亟需设计准确而高效的位置预测方法.针对现有方法的不足,提出了基于高斯混合模型的轨迹预测方法 GMTP,主要步骤包括:(1)针对复杂运动模式利用高斯混合模型建模;(2)利用高斯混合模型计算不同运动模式的概率分布,进而将轨迹数据划分为不同分量;(3)利用高斯过程回归预测移动对象最可能的运动轨迹.GMTP是高斯非线性概率统计模型,其优势在于:计算结果不仅是位置预测值,更是关于移动对象未来所有可能运动轨迹的概率分布,可以利用概率统计分布特性获得某种运动模式(如匀加速运动)下的位置预测.大量真实轨迹数据集上的实验结果表明:与相同参数设置下的高斯回归预测和卡尔曼滤波预测法相比,GMTP的预测准确性平均提高了22.2%和23.8%,预测时间平均缩减了92.7%和95.9%.
