The small-scale dynamo is typically studied by assuming that the correlation time of the velocity field is zero. Some authors have used a smooth renovating flow model to study how the properties of the dynamo are affected by the correlation time being nonzero. Here, we assume the velocity is...
南天山冲断褶皱系是中-上新世以来形成的以薄皮滑脱为主的冲断构造,冲断作用导致了盆地内及周缘区古-新生界的碎屑岩和碳酸盐岩地层发主形变。本文对该冲断系前缘区(巴音库鲁提北部至喀什地区)的运动学特征进行了研究。rn 南天山冲断褶皱系从平面上分出了六个冲断褶皱带。从剖面上划分出两种不同的冲断体系。冲...

Gene-environment (G×E) interaction plays a pivotal role in understanding the genetic basis of complex disease. When environment factors are measured in a continuous scale, one can assess the genetic sensitivity over different environmental conditions on a disease phenotype. Motivated by the increasing...
