The field- and temperature-dependent in-plane resistivity, ρab（T, H）, has been analyzed within the thermally assisted flux-flow（TAFF）formalism. The flux activation energy, U（T, H）, has been extracted from this analysis. The low-T part of the ρab（T, H）data can be described by an activation energy having the functional form of U（T, H） =（1- t）m（H-0/H）β, where t = T /Tc（reduced temperature）, and H0 is a field scale that primarily determines the magnitude of U（T, H）. The temperature exponent, m, shows a systematic variation with p, whereas the field exponent, β, is insensitive to the p values and is close to unity. The H0, on the other hand, changes rapidly as p is varied. U（T, H） is linked to the pinning potential and consequently on the superconducting condensation energy. Since the normal state pseudogap directly affects superconducting condensation energy, a clear correspondence between H0 and the PG energy scale, ε g, is found. Possible implications of these results are discussed.展开更多

Methods: 200 dying cancer patients in our hospital from December 2019 to December 2020 were selected for the study. All the patients were divided into observation group and control group according to the different nursing methods, with 100 cases in one group. The control group was treated with routine nursing, while the observation group was treated with multidisciplinary assistance nursing. At the end of nursing, the quality of life of the two groups was compared. Results: we found that the quality of life of patients with hospice nursing was significantly higher than that of the control group. P < 0.05 showed that the data difference between groups was statistically significant. Conclusion: multidisciplinary assistance palliative nursing has a positive impact on the quality of life of dying patients with cancer, and it can help patients to spend the last stage of life more peaceful and comfortable.展开更多
