Bio-Inspired Fault Diagnosis for Aircraft Fuel Pumps Using a Cloud-Edge System.

The fuel pump serves as the central component of the aircraft fuel system, necessitating real-time data acquisition for monitoring purposes. As the number of sensors increases, there is a substantial rise in data volume, leading to a simultaneous increase in computational processing for traditional Prognostics and Health Management methods while computational efficiency decreases. In response to this challenge, a novel health monitoring approach for aircraft fuel pumps is proposed based on the collaborative utilization of cloud-edge resources.

A performance degradation model of nitrile butadiene rubber (NBR) O-rings for hydrogen permeation effects under high-pressure.

The integration of molecular chain changes on a microscopic scale to achieve macroscopic performance is crucial in degradation processes concerning O-ring seals. Nonetheless, a comprehensive and compelling mathematical model that can describe molecular chains' material properties and macroscopic material properties simultaneously for O-rings under high-pressure conditions is yet to be established. In this paper, we propose a degradation model based on viscoelasticity and molecular chain statistics for hydrogen permeation.

Kidney transplantation at the Chinese People's Liberation Army General Hospital.

Between October 1977 and December 2004, 2,037 kidney transplants were performed in 1,804 patients with ESRD at the Peoples Liberation Army General Hospital Postgraduate Medical School. Overall graft survival rates at one, 5, 10, 15, and 20 years were 91.6%, 79.

[Necessity and safety of conversion from mycophenolate mofetil to AzA thioprine after renal transplantation].

Objective: To investigate the necessity and safety of conversion from mycophenolate mofetil (MMF) to Azathioprine (AzA) in stable renal transplant patients.

Methods: In a randomised open clinical trial, A total of 87 low-risk renal allograft recipients on triple immunosuppressive therapy (prednisone/MMF/cyclosporine) 6 months after transplantation was randomised into two groups: converted (switching MMF to AzA treatment 6 months after transplantation, n = 42) and control (continued MMF treatment, n = 45). Renal function, acute rejection episodes, side effects and related complications were analysed in each group.
