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

TCAD Modeling of the Dynamic VTH Hysteresis Under Fast Sweeping Characterization in p-GaN Gate HEMTs

IEEE Transactions on Electron Devices, 2022
TCAD modeling of the dynamic threshold voltage shift (hysteresis) occurring under fast sweeping characterization in Schottky-type p-GaN gate high-electron-mobility transistors (HEMTs) is reported, to the best of our knowledge, for the first time. Dynamic

Slow magnetic dynamics and hysteresis loops of a bulk ferromagnet [PDF]

, 2011
Magnetic dynamics of a bulk ferromagnet, a new single crystalline compound Co7(TeO3)4Br6, was studied by ac susceptibility and the related techniques. Very large Arrhenius activation energy of 17.2 meV (201 K) and long attempt time (2x10^(-4)s) span the ...

Hysteresis Dynamic Modeling and Analysis of Flexible Nano Silver–Polyvinyl Alcohol Humidity Sensor Based on the Microscopic Process and Langmuir–Fick Theory

ACS Omega, 2022
In recent years, advances in materials science and manufacturing technologies have facilitated the development of flexible sensors. However, there are still performance gaps between emerging flexible sensors and traditional silicon-based rigid sensors ...

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.

A Modified Comprehensive Model for Piezoelectric Stack Actuators and Corresponding Parameter Identification Method

Advances in Materials Science and Engineering, 2015
In order to accurately model the hysteresis and dynamic characteristics of piezoelectric stack actuators (PSAs), consider that a linear force and a hysteresis force will be generated by piezoelectric wafers under the voltage applied to a PSA, and the ...

Vehicle dynamics with brake hysteresis [PDF]

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2012
This paper studies hysteresis of vehicle brakes and its influence on the vehicle dynamics. The experimental investigation clearly shows the non-linear and asymmetric characteristics of hysteresis of the disk brakes in passenger cars. A computational model of the brake mechanism with hysteretic elements, based on the Bouc–Wen method, is developed and ...

Theory of Hysteresis Loop in Ferromagnets [PDF]

, 1998
We consider three mechanisms of hysteresis phenomena in alternating magnetic field: the domain wall motion in a random medium, the nucleation and the retardation of magnetization due to slow (critical) fluctuations.

Research on the Dynamic Hysteresis Loop Model of the Residence Times Difference (RTD)-Fluxgate

Sensors, 2013
Based on the core hysteresis features, the RTD-fluxgate core, while working, is repeatedly saturated with excitation field. When the fluxgate simulates, the accurate characteristic model of the core may provide a precise simulation result.

Orientational hysteresis in swarms of active particles in external field

, 2015
Structure and ordering in swarms of active particles have much in common with condensed matter systems like magnets or liquid crystals. A number of important characteristics of such materials can be obtained via dynamic tests such as hysteresis.
