Experimental and molecular epidemiological studies indicate important roles for adipose tissue or high-fat diet (HFD) in tumor growth and metastasis. Gastric cancer (GC) possesses a metastatic predilection for the adipocyte-rich peritoneum. However,

It is generally acknowledged that the failure of the layer-crack structure is closely related to rock bursts (a layer-crack structure means a coal or rock rib that is cut by fractures that are parallel or sub-parallel to the surface of the rib). Unde
