Machine learning-based rail corrugation recognition: a metro vehicle response and noise perspective
Philosophical Transactions of the Royal Society A, 2023 Rail corrugation is a common problem in metro lines, and its efficient recognition is always an issue worth studying. To recognize the wavelength and amplitude of rail corrugation, a particle probabilistic neural network (PPNN) algorithm is developed ...

Vehicle-track dynamic interaction analysis of a metro vehicle
IOP Conference Series: Materials Science and Engineering, 2020 Abstract In this paper, comparison of results between the self-programming model (considering the track flexibility) and SIMPACK model (considering only fastener support) is carried out. The wheelset vibration is more obviously for the self-programming model as the track flexibility is considered. For the traditional dynamic calculation,

Macrophage‐derived MLKL in alcohol‐associated liver disease: Regulation of phagocytosis
Hepatology, EarlyView., 2022 EtOH causes leaky gut allowing bacteria and PAMPs into the liver, resulting in hepatic inflammation and injury. We demonstrate that LPS induces STAT1‐mediated expression and phosphorylation of MLKL in macrophages and identify a novel function that myeloid MLKL translocates to phagosomes and lysosomes and regulates phagocytosis, which contributes to the

Wear rates in urban rail systems [PDF]
, 2017 A significant part of maintenance costs in urban rail systems (metro, tram, light rapid transit/light metro) is due to wheel-rail wear. Wear rates - measured for example as depth of wear per kilometre run (rolling stock) or per train passage (rails ...
