A research team has investigated quasar variability by tracking optical to mid-infrared (MIR) wavelengths of variability ...
Abstract: Extended dispersion entropy-based Lempel–Ziv complexity (EDELZC) can measure the irregularity or chaos of single-channel time series, which is one of the ideal tools for extracting fault ...
Abstract: Urban metro systems (UMS) consist of complex equipment and facility systems (CEFS), characterized by interdependencies, cascading failure effects, limited risk tolerance, and significant ...
