DOI: 10.1080/00223131.2018.1467285
Abstract: ABSTRACT Frequent beam trips as experienced in existing high-power proton accelerators may cause thermal fatigue in Accelerator-Driven System components. In order to overcome the beam-trip problem, the beam-trip frequencies were estimated based on operational data… read more here.

DOI: 10.1103/physreve.104.024133
Abstract: Periodic environmental changes are commonly observed in nature from the amount of daylight to seasonal temperature. These changes usually affect individuals' death or birth rates, dragging the system from its previous stable states. When the… read more here.
