Suppressing Spurious Causal Chains in Alarm-Triggered Alarm Phenomena via Liang–Kleeman Information Flow–Max-Min Hill-Climbing Graphs

Due to coupling in industrial control structures, alarm variables may exhibit interconnected variations, leading to the “alarm-triggered alarm” phenomenon, which can contribute to alarm flooding. Causal inference methods can characterize dependencies among alarm variables and hel...

Cross-scale mechanistic investigation of multistage carbon dioxide pool flash evaporation with vertical heterogeneity

Pool flash evaporation is a canonical liquid–vapor phase-change process driven by rapid depressurization, yet the stage-dependent flow-pattern evolution and vertical thermodynamic heterogeneity remain poorly understood. Existing heat and mass transfer models treat the process as...

Inhibition mechanism of OH/F doping on radiation-induced optical degradation of amorphous silica

Irradiation-induced formation of color centers in amorphous silica often deteriorates the optical performance of the material, thereby significantly affecting its long-term service performance. At present, the mechanism underlying the inhibition of color centers induced optical p...
