Methods: Adult patients who underwent enterostomy surgery in our gastroenterology department with negative emotions and insomnia between August 2021 and August 2022 were selected as research objects and randomly divided into “3H” nursing mode group and conventional nursing management group. For the conventional nursing group, routine standard nursing mode was adopted after enterostomy, while extra systematic “3H” nursing service on the basis of conventional nursing management was applied for its counterpart. SAS and SDS scores, Pittsburgh sleep quality index, Barthel index and nursing satisfaction were compared between the two groups. Results: SAS and SDS scores, Pittsburgh sleep quality index, Barthel index and nursing satisfaction of “3H” nursing mode group were evidently better than those of conventional nursing management group, and the difference was significant (P Conclusion: The “3H” nursing mode can effectively improve negative emotions of patients with enterostomy, such as anxiety and depression, improve their sleep quality and self-care ability in daily life, and play an important role in building a harmonious relationship between doctors and patients, nurses and patients, which is worthy of clinical application.展开更多

Pumped by a 976-nm fiber-coupled diode laser with 50-ktm core diameter, stable mode-locked laser pulses up to 430 mW were obtained at a repetition rate of 83.61 MHz under 5-W pump power. The autocorrelation measurement shows that the pulse duration is as short as 150 fs by assuming the sech2 pulse shape at a central wavelength of 1048 nm. This work has demonstrated a compact and reliable femtosecond laser source for prospective low-cost applications.展开更多

This control scheme consists of two combined controllers, One is the global sliding mode controller for practical plant, the other is the integral backstepping controller for nominal model. Modeling error between practical plant and nominal model is used to design GSMC. The steady-state control accuracy can be guaranteed by the integral backstepping control law, and the global robustness can be obtained by GSMC. The stability of the proposed controller is proved according to the Lyapunov approach. The simulation results both of sine signal and step signal tracking for 3-axis flight table are investigated to show good position tracking performance and high robustness with respect to large and parameter changes over all the response time.展开更多
