We investigate the control of electron injection in the cascaded laser wakefield accelerators, optimization of seeding phase and the self-guided propagation of laser pulses between the two accelerators. The maximum acceleration gradient with energy spread narrowing was obtained when the seeding phase and the laser pulse propagation were optimized.

Fan, Shenggen, Li, Lixing, and Zhang, Xiaobo-Challenges of creating cities in China: Lessons from a short-lived county-to-city upgrading policy #n#It has been widely observed that China is under-urbanized. The central government has tried to use various policies to promote urbanization. In this paper, we evaluate one of these policies - count-to-city upgrading. Under China's hierarchical governance structure, a city status can only be determined and awarded by the central government. In the 1980s and 1990s, China adopted a formula-based county-to-city upgrading policy. Based on a large panel dataset covering all counties in China, we find that the formula was not strictly enforced in the practice. Moreover, jurisdictions that were upgraded to cities prior to 1998 do not perform better than their counterparts that remained county status in terms of both economic growth and providing public services. Largely because of these problems, this policy was called off in 1997. Given the strong need for urbanization, more indigenous institutional innovations are needed to find a viable way of creating cities, which would also provide compatible incentives to local governments.

You Z, Jiang D, Stamnes J, Chen J, Xiao J. Characteristics and applications of two-dimensional light scattering by cylindrical tubes based on ray tracing. APPLIED OPTICS. 2012;51:8341-8349.Abstract
The intensity distribution of light scattered by a capillary tube filled with a liquid is studied using geometrical optics or ray tracing. Several intensity step points are found in the scattering pattern due to contributions from different geometrical rays. The scattering angles of these intensity step points vary with the capillary parameters, i.e., with the inner and outer radii of the capillary wall and the refractive indices of the liquid and the wall material. The relations between the scattering angles of the step points and the capillary parameters are analyzed using the reflection law and Snell's law. A method is developed to determine the capillary parameters from measurements of the scattering angles of the step points. An experiment is designed to provide measured data from which the capillary parameters can be obtained by the proposed method. It is shown that this method provides capillary parameters of high precision. (c) 2012 Optical Society of America
Hu WW, Hu M, Deng ZQ, Xiao R, Kondo Y, Takegawa N, Zhao YJ, Guo S, Zhang YH. The characteristics and origins of carbonaceous aerosol at a rural site of PRD in summer of 2006. Atmospheric Chemistry and PhysicsAtmospheric Chemistry and Physics. 2012;12:1811-1822.Abstract
Both organic carbon (OC) and elemental carbon (EC) were measured during PRIDE-PRD 2006 summer campaign by using a semi-continuous thermal-optical carbon analyzer at a rural site, Back Garden (BG), which is located 50 km to the northwest of Guangzhou City. Together with the online EC/OC analyzer, various kinds of instruments related to aerosol chemical properties were employed here, which provided a good opportunity to check data quality. The concentrations of OC correlated well with the mass of organic matter (OM) and water soluble organic carbon (WSOC), implying the reliability of the data measured in this campaign. The average OC concentrations in fine particle for three typical periods during the campaign (local emission influence, typhoon and precipitation and normal days) were 28.1 mu gC m(-3), 4.0 mu gC m(-3) and 5.7 mu gC m(-3), respectively; and EC were 11.6 mu gC m(-3), 1.8 mu gC m(-3), and 3.3 mu gC m(-3), respectively. The diurnal patterns of EC and OC during the campaign were higher at night and in early morning than daytime, which was probably caused by the primary emission and accumulation in the occurrence of low boundary layer. Compared with the constant diurnal enhancement ratios of EC, the enhancement ratio of OC (OC versus (CO-CObackground)) kept in a relative high level in the afternoon, with a similar diurnal profile to oxygenated organic aerosol (OOA), due to the strong photochemical formation of OC. Here, a modified EC tracer method was used to estimate the formation of secondary organic carbon (SOC). These results showed that the average SOC concentration (normal days) at BG site was about 2.0 +/- 2.3 mu gC m(-3), and the SOC fraction in OC could reach up to 80% with the average of 47 %. The modified approach in this study proved to be effective and reliable for SOC estimation based on good correlations between estimated SOC versus OOA or WSOC, and estimated POC versus hydrocarbon-like organic aerosol (HOA).
