Dynamical Hysteresis without Static Hysteresis: Scaling Laws and Asymptotic Expansions [PDF]
SIAM Journal on Applied Mathematics, 1997 Summary: We study dynamical hysteresis in a simple class of nonlinear ordinary differential equations, namely first-order equations subject to sinusoidal forcing. The assumed nonlinearities are such that the area of the hysteresis loop vanishes as the forcing frequency tends to zero; in other words, there is no static hysteresis.

Surface mobility and structural transitions of poly(n-alkyl methacrylates) probed by dynamic contact angle measurements [PDF]
, 1986 Dynamic contact angles and contact-angle hysteresis of a series of poly(n-alkyl methacrylates) (PAMA) were investigated using the Wilhelmy plate technique.

Dynamics of successive minor hysteresis loops [PDF]
Physical Review B, 2012 Cumulative growth of successive minor hysteresis loops in Co/Pd multilayers with perpendicular anisotropy was studied in the context of time dependent magnetization reversal dynamics. We show that in disordered ferromagnets, where magnetization reversal involves nucleation, domains' expansion and annihilation, differences between the time dependencies ...

Investigation of scaling properties of hysteresis in Finemet thin films [PDF]
, 2004 We study the behavior of hysteresis loops in Finemet Fe$_{73.5}$Cu$_1$Nb$_3$Si$_{18.5}$B$_4$ thin films by using a fluxometric setup based on a couple of well compensated pickup coils.

Relaxation in Population Dynamics Models with Hysteresis [PDF]
SIAM Journal on Control and Optimization, 2021 The present paper is concerned with a nonlinear partial differential control system subject to a state-dependent and nonconvex control constraint. This system models the dynamics of populations in the vegetation--prey--predator framework and takes account of diffusive and hysteresis effects appearing in the process.

Scaling dynamic response and destructive metabolism in an immunosurveillant anti-tumor system modulated by different external periodic interventions. [PDF]
PLoS ONE, 2011 On the basis of two universal power-law scaling laws, i.e. the scaling dynamic hysteresis in physics and the allometric scaling metabolism in biosystem, we studied the dynamic response and the evolution of an immunosurveillant anti-tumor system subjected

Hidden hysteresis – population dynamics can obscure gene network dynamics [PDF]
Journal of Biological Engineering, 2013 Positive feedback is a common motif in gene regulatory networks. It can be used in synthetic networks as an amplifier to increase the level of gene expression, as well as a nonlinear module to create bistable gene networks that display hysteresis in response to a given stimulus. Using a synthetic positive feedback-based tetracycline sensor in E.

Comparator with dynamic hysteresis
Electronics Letters, 1999 A comparator is presented which is based on the use of a time domain phenomenon called 'dynamic hysteresis'. This comparator features only one threshold and a short-time controllable noise immunity.
