In China there are approximately 100 pig breeds, which show great diversity in their appearance. However, information on genome selection signatures, such as spine curvature, is scarce. Therefore, we used the fixation index (FST) and cross‐population extended haplotype homozygosity (XPEHH) methods to explore the genome selection signatures of spine curvature in six breeds of Chinese indigenous pig...
Based on the disturbing effect mechanism of shield construction on surrounding soil and buildings, the construction process of shield tunnel down-crossing nearby existing tunnel is simulated with the FLAC-3D numerical simulation software, taking the engineering situation of a shield section tunnel in Beijing Subway as research objects. The disturbing effect on existing tunnel caused by shield tunnel...
