Stochastic approach for assessing the predictability of chaotic time series using reservoir computing
Igor A Khovanov
The applicability of machine learning for predicting chaotic dynamics relies heavily upon the data used in the training stage. Chaotic time series obtained by numerically solving o…
The response of a bistable energy harvester to different excitations: the harvesting efficiency and links with stochastic and vibrational resonances
Igor A Khovanov
Energy harvesting of ambient vibrations using a combination of a mechanical structure (oscillator) and an electrical transducer has become a valuable technique for powering small w…
Mechanism of the Resonant Enhancement of Electron Drift in Nanometre Semiconductor Superlattices Subjected to Electric and Inclined Magnetic Fields
Stanislav M. Soskin, Igor A. Khovanov, Peter V. E. McClintock
We address the increase of electron drift velocity that arises in semiconductor superlattices (SLs) subjected to constant electric and magnetic fields. It occurs if the magnetic fi…
Frequency stabilization and noise-induced spectral narrowing in resonators with zero dispersion
L. Huang, S. M. Soskin, I. A. Khovanov +3
Mechanical resonators are widely used as precision clocks and sensitive detectors that rely on the stability of their eigenfrequencies. The phase noise is determined by different f…
Regular Rather than Chaotic Origin of the Resonant Transport in Superlattices
S. M. Soskin, I. A. Khovanov, P. V. E. McClintock
We address the enhancement of electron drift in semiconductor superlattices of nanometre scale that occurs in combined electric and tilted magnetic fields if Bloch oscillations bec…
Numerical simulations versus theoretical predictions for a non-Gaussian noise induced escape problem in application to full counting statistics
I. A. Khovanov, N. A. Khovanova
A theoretical approach for characterising the influence of asymmetry of noise distribution on the escape rate of a multi-stable system is presented. This was carried out via the es…
Intrinsic dynamics of heart regulatory systems on short time-scales: from experiment to modelling
I. A. Khovanov, N. A. Khovanova, P. V. E. McClintock +1
We discuss open problems related to the stochastic modeling of cardiac function. The work is based on an experimental investigation of the dynamics of heart rate variability (HRV)…
A New Approach To The Treatment Of Separatrix Chaos And Its Applications
S. M. Soskin, R. Mannella, O. M. Yevtushenko +2
We consider time-periodically perturbed 1D Hamiltonian systems possessing one or more separatrices. If the perturbation is weak, then the separatrix chaos is most developed when th…
Noise-induced failures of chaos stabilization: large fluctuations and their control
I. A. Khovanov, N. A. Khovanova, P. V. E. McClintock
Noise-induced failures in the stabilization of an unstable orbit in the one-dimensional logistic map are considered as large fluctuations from a stable state. The properties of the…
