Amplitude Modulation of Short-timescale Hot Spot Variability [PDF]
The Astrophysical Journal, 2021 Abstract Variability of Classical T Tauri stars (CTTS) occurs over a vast range of timescales. CTTS in particular are subject to variability caused by accretion shocks, which can occur stochastically, periodically, or quasi-periodically on timescales over a few days.

Quasar variability: Correlations with amplitude [PDF]
Astronomy and Astrophysics Supplement Series, 2000 The relation between quasar variability and parameters such as luminosity and redshift has been a matter of hot debate over the last few years with many papers on the subject. Any correlations which can be established will have a profound effect on models of quasar structure and evolution.

On the assessment of multiaxial fatigue damage under variable amplitude loading [PDF]
Fracture and Structural Integrity, 2016 In this work, the performance of the SSF criterion is evaluated under variable amplitude loading conditions. The main objective was to inspect the validity of the hypothesis in which the SSF damage map remains valid for any high strength steel.

Prediction of Fatigue Crack Initiation under Variable Amplitude Loading: Literature Review
Metals, 2023 Metallic materials are widely employed in engineering constructions, and one of the most common failure mechanisms in metals is fatigue failure. Even though metal fatigue has been studied for almost 160 years, many problems remain unsolved.

Finite amplitude thermal convection with variable gravity
International Journal of Mathematics and Mathematical Sciences, 2001 Finite amplitude thermal convection is studied in a horizontal layer of infinite Prandtl number fluid with a variable gravity. For the present study, gravity is restricted to vary quadratically with respect to the vertical variable.
