Degradation Data Analysis Using a Wiener Degradation Model With Three-Source Uncertainties

IEEE Access, 2019
The degradation data have been widely applied in reliability analysis for deteriorating systems. However, the degradation data are usually contaminated by measurement errors that can severely affect the life estimation performance.

Clinical and cost effectiveness of endoscopic bipolar radiofrequency ablation for the treatment of malignant biliary obstruction: a systematic review

Health Technology Assessment, 2023
Background Early evidence suggests that using radiofrequency ablation as an adjunct to standard care (i.e. endoscopic retrograde cholangiopancreatography with stenting) may improve outcomes in patients with malignant biliary obstruction.

Analysis of multiple lightning overvoltage on 110 kV transmission lines

Results in Engineering
As pointed out by the CIGRE TB 549 report issued by the International Power Grid Committee, >80 % of cloud-to-ground lightning are multiple lightning strokes (MLS), posing a severe threat to overhead transmission lines.

Modelling perception-action coupling in the phenomenological experience of “hitting the wall” during long-distance running with exercise-induced muscle damage in highly trained runners

Sports Medicine - Open, 2018
Background “Hitting the wall” (HTW) can be understood as a psychophysiological stress process characterised by (A) discrete and poignant onset, (B) dynamic interplay between physiological, affective, motivational, cognitive, and behavioural systems, and (
