Hopf bifurcation analysis in a diffusive predator–prey system with spatial heterogeneity and delays
In this paper, we consider a diffusive Lotka–Volterra predator–prey system with spatial heterogeneity and two delays. We first show that there exists a nonconstant positive steady state when the diffusion rate...

An Improved Conditional Euclidean Clustering Point Cloud Segmentation Method
In response to the problem that the traditional segmentation algorithm is not ideal for segmenting point cloud data in parts with large changes in geometric features and complex shapes, a conditional Euclidean...

Open AccessTouch-Responsive Hydrogel for Biomimetic Flytrap-Like Soft Actuator
A pioneering touch-responsive material with multiple responsiveness to touch stimulation (i.e., spatial contact with foreign object) is successfully develo...

Bifurcation analysis in delayed Nicholson blowflies equation with delayed harvest
In this paper, we investigate a delayed Nicholson equation with delay harvesting term which was proposed in open problems and conjectures formulated by Berezansky et al. (Appl. Math. Model. 34: 1405–1417, 2010...

Bifurcation analysis in a nonlinear electro-optical oscillator with delayed bandpass feedback
The dynamics of a nonlinear electro-optical oscillator with delayed bandpass feedback is investigated. By analyzing the distribution of the eigenvalues, the existence and stability of Hopf bifurcations are obt...

Analyzing global stability of a viral model with general incidence rate and cytotoxic T lymphocytes immune response
The global dynamics of a viral model with general incidence rate and CTL immune response is investigated. We derive the basic reproduction number for viral infection

Stability and bifurcation analysis of a diffusive prey–predator system in Holling type III with a prey refuge
A diffusive prey–predator system with Holling type III response function incorporating a prey refuge subject to Neumann boundary conditions is considered. The sufficient conditions are given to ensure that the...

Stability and bifurcation analysis in the cross-coupled laser model with delay
The dynamics of the cross-coupled laser model with delay has been investigated. The investigation confirms that a Hopf bifurcation occurs due to the existence of stability switches when the product of the coup...

Hopf bifurcation analysis in synaptically coupled HR neurons with two time delays
This paper presents an investigation of stability and Hopf bifurcation of a synaptically coupled nonidentical HR model with two time delays. By regarding the half of the sum of two delays as a parameter, we fi...

Bifurcation analysis of Mackey–Glass electronic circuits model with delayed feedback
In this paper, we consider a coupled Mackey–Glass electronic circuits model with two delays, which has been proposed by Sano et al. (Phys. Rev. E 75:016207, 2007). At first, we investigate the stability and occur...

Normal forms for NFDEs with parameters and application to the lossless transmission line
A method for the computation of normal forms for neutral functional differential equations (NFDEs) with parameters is developed by considering an extension of phase space, based on the method of computing nor...

Bifurcation analysis in a time-delay model for prey–predator growth with stage-structure
A time-delay model for prey–predator growth with stage-structure is considered. At first, we investigate the stability and Hopf bifurcations by analyzing the distribution of the roots of associated characteris...
