Multi-variable H-β optimization approach for the lateral support design of a wide field survey telescope.

We have proposed a multi-variable H-β optimization approach (MHOA). Compared with the conventional push-pull-shear lateral support optimization (CPLSO), which has only one design variable, β, MHOA adds another design variable, H, which is the support position height. By contrast, the support position height of CPLSO is usually fixed at mid-thickness, H (or at H, the height of the center of gravity for the mirror), on the outer rim of the mirror blank.

Epidemiological study on Clonorchis sinensis infection in Shenzhen area of Zhujiang delta in China.

To study the transmission route and epidemiological features of Clonorchis sinensis infection in Shenzhen area, which is the biggest immigration city in the south of China, we examined 1,473 individuals (710 males and 763 females) to assess the current status of C. sinensis infection among the people in a village of Shenzhen in Zhujiang delta of Guangdong province, China. Freshwater snails, 630, of different species known as the first intermediate host of C.
