Deneb Is a Large-amplitude Polarimetric Variable
The Astrophysical Journal LettersWe write to report the discovery that Deneb is a large-amplitude polarization variable. Over a ∼400 days time span from 2022 August Deneb’s polarization was typically around 3900 parts per million (ppm) in the SDSS ${g}^{{\prime} }$ band.

REINFORCING SACCADIC AMPLITUDE VARIABILITY [PDF]
Journal of the Experimental Analysis of Behavior, 2011 Saccadic endpoint variability is often viewed as the outcome of neural noise occurring during sensorimotor processing. However, part of this variability might result from operant learning. We tested this hypothesis by reinforcing dispersions of saccadic amplitude distributions, while maintaining constant their medians.

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.

Small amplitude variable red giants [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractSmall amplitude variable red giants were discovered long time ago (Eggen 1969, Henry et al. 2000, Jorison et al. 1997). The revolutionary turning point for the study of this type of variable was due to the work of Wood (2000) and Soszyński et al.

Non-local energy based fatigue life calculation method under multiaxial variable amplitude loadings [PDF]
, 2013 Reliable design of industrial components against high cycle multiaxial fatigue requires a model capable of predicting both stress gradient and load type effects. Indeed, taking into account gradient effects is of prior importance for the applicability of

A New Small-Amplitude Variable Hot DQ White Dwarf [PDF]
, 2010 We present the discovery of photometric variations in the carbon-dominated atmosphere (hot DQ) white dwarf star SDSS J133710.19-002643.6. We find evidence for two low-amplitude, harmonically-related periodicities at 169 s and 339 s, making it the fastest

A progressive damage fatigue model for unidirectional laminated composites based on finite element analysis: theory and practice [PDF]
Fracture and Structural Integrity, 2018 The simulation of the fatigue damage of laminated composites under multi-axial and variable amplitude loadings has to deal with several new challenges and several methods of damage modelling.

Contradiction of Quantum Mechanics with Local Hidden Variables for Continuous Variable Quadrature Phase Amplitude Measurements [PDF]
, 1998 We demonstrate a contradiction of quantum mechanics with local hidden variable theories for continuous variable quadrature phase amplitude (``position'' and ``momentum'') measurements, by way of a violation of a Bell inequality.
