The soil slopes in nature are normally unsaturated, heterogeneous, and even carry cracks. In order to assess the stability of slope with crack under steady unsaturated flow and non-uniform conditions, this work proposes a novel discretization-based method to generate the rotational failure mechanism...

We performed volatile and nonvolatile metabolome analysis of Zhuyeqi (Z) and Baihaozao (B) dark teas during three stages of tea processing: (1) after withering and kneading (S), (2) after pile-fermenting (M), and (3) during drying and second kneading (Z). Our results indicate that the Z variety was...
