Spatial Nonlinear Analysis of the Reasonable Cable Tension for a Thousand-meter Scale Cable-stayed Bridge

Zhang Jianmin,Xiao Rucheng

Strategic Study of CAE 2004, Volume 6, Issue 12,   Pages 37-42

Abstract:

In this paper, a model for spatial nonlinear optimization programming to obtain the prestresses of cables in the cable-stayed bridge is established, in which the bending strain energy of the beams for the bridge and the cable tower is the objective function, and structural stresses and the cable forces are the constraint conditions. In order to determine the prestresses of the cables of the bridge, the first order optimization method is used to solve the program. This method is used to obtain set of optimal cable tensions of a thousand-meter scale cable-stayed bridge under permanent loads, and the result of analysis showed that the method is easy to apply and effective.

Genome-wide association studies: inherent limitations and future challenges

Yan Du, Jiaxin Xie, Wenjun Chang, Yifang Han, Guangwen Cao

Frontiers of Medicine 2012, Volume 6, Issue 4,   Pages 444-450 doi: 10.1007/s11684-012-0225-3

Abstract:

Genome-wide association studies (GWAS) have achieved great success in identifying genetic variants related to complex human diseases such as cancer and have provided valuable insights into their genetic architecture. Recently, GWAS is quite the fashion in China. However, there are issues related to its nature. Enormous work needs to be done in the post-GWAS era. Deep sequencing followed by functional studies will be needed to elucidate the underpinning biological mechanisms and further translate GWAS findings into medical practice. Along with pharmacogenomics, the success of GWAS in identifying genetic risk factors and genetic differences in drug response has been gradually enabling personalized medicine. In this article, we used hepatocellular carcinoma (HCC) as an example to demonstrate some of the inherent limitations and summarized future challenges of GWAS.
