Anisotropic Magneto-conductance of InAs Nanowire: Angle Dependent Suppression of 1D Weak Localization

The magneto-conductance of an InAs nanowire is investigated with respect to the relative orientation between external magnetic field and the nanowire axis. It is found that both the perpendicular and the parallel magnetic fields induce a positive magneto-conductance. Yet the parallel magnetic field induced longitudinal magneto-conductance has a smaller magnitude. This anisotropic magneto-transport phenomenon is studied as a function of temperature, magnetic field strength and at an arbitrary angle between the magnetic field and the nanowire. We show that the observed effect is in quantitative agreement with the suppression of one-dimensional (1D) weak localization

Application of Nursing Risk Management in Patients with Cardiovascular Emergencies

Objectives: To study the nursing effect of nursing risk management in patients with acute cardiovascular disease. Methods: A total of 62 acute and critical cardiovascular patients admitted to the Second People's Hospital of Shandong Province from November 2021 to January 2023 were selected as the study objects, and the patients were randomly divided into control group and observation group. The control group adopted conventional nursing methods, while nursing risk management measures were carried out in the observation group. The nursing effects of the two groups were compared, and the incidence rate and patient satisfaction were analyzed according to the time. Results: The effective rate of the observation group was 93.55%, significantly higher than 61.29% of the control group, and the difference was statistically significant(P<0.05). The occurrence of risk events in observation group was significantly less than that in control group, and patient satisfaction was significantly higher than that in control group (P<0.05). Conclusion: Nursing risk management could significantly improve the nursing effect of patients, reduce the occurrence of risk events, improve patient satisfaction, has a certain application value
