QZS isolators with multi-pairs of oblique bars for isolating ultralow frequency vibrations
Quasi-zero stiffness (QZS) vibration isolators have been intensively studied due to their importance in isolating low-frequency vibration, but isolating the ultralow frequency vibration and supporting variable...

Internal signal stochastic resonance of a two-component gene regulatory network under Lévy noise
Noises are ubiquitous in nature and can often induce some curious phenomena. In this paper, we investigate the internal signal stochastic resonance (ISSR) phenomenon of a two-component gene regulatory network ...

One-to-three resonant Hopf bifurcations of a maglev system
This paper studies the dynamics of a maglev system around 1:3 resonant Hopf–Hopf bifurcations. When two pairs of purely imaginary roots exist for the corresponding characteristic equation, the maglev system ha...

Secondary resonances of a quadratic nonlinear oscillator following two-to-one resonant Hopf bifurcations
Stable bifurcating solutions may appear in an autonomous time-delayed nonlinear oscillator having quadratic nonlinearity after the trivial equilibrium loses its stability via two-to-one resonant Hopf bifurcati...

Effect of External Excitations on a Nonlinear System with Time Delay
The trivial equilibrium of a two-degree-of-freedom autonomous system may become unstable via a Hopf bifurcation of multiplicity two and give rise to oscillatory bifurcating solutions, due to presence of a time...

Bifurcation Control of a Parametrically Excited Duffing System
A linear time-delayed feedback control is used to delay the occurrenceof pitchfork bifurcations and to eliminate saddle-node bifurcations,which may arise in the nonlinear response of a parametrically excitedDu...

Local Bifurcation Control of a Forced Single-Degree-of-Freedom Nonlinear System: Saddle-Node Bifurcation
It is well known that saddle-node bifurcations can occur in the steady-state response of a forced single-degree-of-freedom (SDOF) nonlinear system in the cases of primary and superharmonic resonances. This dis...
