Abstract: The effect of demographic stochasticity, in the form of Gaussian white noise, in a predator-prey model with one fast and two slow variables is studied. We derive the stochastic differential equations (SDEs) from a discrete… read more here.

DOI: 10.1063/1.5053597
Abstract: We present electrostatic Micro-Electromechanical System actuators equipped with dimples and contact pads. The introduction of dimples and contact pads is shown to prevent stiction between the actuator and bottom electrodes and minimize dielectric charging and… read more here.

DOI: 10.1063/5.0098708
Abstract: A model for two symmetrically coupled lasers is investigated, in which mixed-mode oscillations arise in the absence of coupling. For small enough coupling, we show that in the time series, certain dynamical transitions from different… read more here.

DOI: 10.1063/5.0194934
Abstract: In the phenomenon of mixed-mode oscillations, transitions between large-amplitude and small-amplitude oscillations may lead to anomalous jitter in the probe of a tapping mode atomic force microscope (TM-AFM) during the scanning process, thereby affecting the… read more here.

DOI: 10.1088/1402-4896/adc0c8
Abstract: Typically, different bifurcation structures of the multiscale systems can induce different mixed-mode oscillations, but bifurcation structures are not the only factor leading to the mixed-mode oscillations. In this paper, we aim to investigate the coupling… read more here.

DOI: 10.1093/mnras/stae027
Abstract: In a previous paper we have suggested that two-armed disc deformation excites two- or three-armed disco-seismic c-mode oscillations by three-mode resonant coupling processes. This might be one of possible causes of the QPOs observed in… read more here.
