基于第一性原理计算CuxNi19-x（x<19）混合团簇的结构研究

采用基于第一性原理计算的Chen-Mbius三维晶格反演基础上获得的原子间相互作用势参数,运用最陡下降法和共轭梯度法结合起来的最优化计算Smart方法得到了CuxNi19-x(x<19)二元过渡金属混合团簇的稳态构型,发现Cu-Ni混合团簇中有明显Cu元素偏析现象,即Cu和Ni并没有互相混合形成有序结构,而是分别聚集在一起,所形成的体系对称性很低,呈割据状态。

Can PC format CV reveal the true value of environmental resources in developing countries？ A laboratory experiment in China

This is a report on payment card format contingent valuation prediction validity in China based on the individual level comparison in a world heritage site evaluation. An evaluation index system of indicators is set up according to the consistency of the individual willingness to pay as well as the mean （or median）, the positive （or negative） proportion in the hypothetical context and those in the actual donation context. We took the conservation of a combined world heritage site Wuyi Mountain in China as the case study. By one-to-one individual level comparison, we demonstrate that people usually overstate their paying intention and overestimate their paying abilities, and the hypothetical individual WTP, mean, median, positive proportion and negative proportion are all significantly different from those in the actual context in this case. However, although the relationship between WTP and socioeconomic characteristics in the hypothetical context was not consistent with that in the actual situation, the survey still demonstrated the maximum support proportion and the least opponent proportion to the project when it was carried out. So we can conclude that in this case PC format CV is a poor indicator, partly owning to its free binding. We also find that when a person decides whether to pay （intention）, he or she is more affected by his/her knowledge structure and social duty; when he/she really decides on how much he/she will pay, income becomes the most important factor.     

Rapid induction of mRNAs forPC3 by partial hepatectomy and epidermal growth factor

The expression of immediate early gene plays a pivotal role in rat hepatocyte proliferation from G₀ to G₁ phases and the progression through G₁ phase of the cell cycle within several hours after 2/3 hepatectomy. We investigated the different gene expressions within 1 h after 2/3 hepatectomy by representational difference analysis. Sequence analysis indicated thatPC3 induced by NGF was a kind of immediate early gene and might be correlated with liver regeneration. Moreover, we found that 2/3 hepatectomy could induce the expressing ofPC3 mRNA by Northern blot with a peak 1–2 h after surgery. In primary cultures of rat hepatocytes, addition of EGF resulted in rapid and transient induction ofPC3 mRNA. It was first reported thatPC3 gene belongs to immediate early gene associated with liver regeneration.
