Superconducting and topological states are two most intriguing quantum phenomena in solid materials. The entanglement of these two states, the topological superconducting state, will give rise to even more exotic quantum phenomena. While many materials are found to be either a superconductor or a topological insulator, it is very rare that both states exist(More)
The latest discovery of possible high-temperature superconductivity in the single-layer FeSe film grown on a SrTiO3 substrate has generated much attention. Initial work found that, while the single-layer FeSe/SrTiO3 film exhibits a clear signature of superconductivity, the double-layer film shows an insulating behaviour. Such a marked layer-dependent(More)
In high-temperature cuprate superconductors, it is now generally agreed that superconductivity is realized by doping an antiferromagnetic Mott (charge transfer) insulator. The doping-induced insulator-to-superconductor transition has been widely observed in cuprates, which provides important information for understanding the superconductivity mechanism. In(More)
From July 1958 to June 1978, a total of 333 cases with pathologically proven primary liver cancer (PLC) were admitted to the Zhong Shan Hospital, Shanghai Medical University, Shanghai, the people's Republic of China. Of these, 39.6% (132 of 333) were resected and 14.4% (19 of 132) survived over 10 years after resection for PLC. These 19 patients surviving(More)
During the period of 1958-1986, a series of 125 patients with pathologically proven hepatocellular carcinoma (HCC) surviving more than 5 years was collected in authors' institute. Thirty seven of them survived more than 10 years, the longest being 30 years. Of the entire series, 55.2% of patients was discovered by screening, 48.0% of patients was(More)
