Background: Modifiable atherosclerotic cardiovascular disease risk factors are hypertension, diabetes mellitus, dyslipidemia, cigarette smoking, and obesity; the term coronary artery bifurcation is used when a coronary artery divides into two ...

Dynamics of a Discrete Leslie–Gower Model with Harvesting and Holling-II Functional Response
Recently, Christian Cortés García proposed and studied a continuous modified Leslie–Gower model with harvesting and alternative food for predator and Holling-II functional response, and proved that the model undergoes transcritical bifurcation, saddle ...

Behavior Analysis of a Class of Discrete-Time Dynamical System with Capture Rate
In this paper, we study the stability and bifurcation analysis of a class of discrete-time dynamical system with capture rate. The local stability of the system at equilibrium points are discussed.

Bifurcation of Nonlinear Equations: II. Dynamic Bifurcation [PDF]
[Part 1 appeared ibid., 155--178 (1994; Zbl 1095.47027), see the preceding review.] The authors study dynamic bifurcation when the eigenvalue of the linearized problem has algebraic multiplicity one or two. As in the first part of the work for steady state bifurcations, their key idea is to analyze precisely the effect of the higher-order nondegenerate

Computational Analysis and Bifurcation of Regular and Chaotic Ca2+ Oscillations
This study investigated the stability and bifurcation of a nonlinear system model developed by Marhl et al. based on the total Ca2+ concentration among three different Ca2+ stores.

On the Relationship between Equilibrium Bifurcations and Ideal MHD Instabilities for Line-Tied Coronal Loops [PDF]
For axisymmetric models for coronal loops the relationship between the bifurcation points of magnetohydrodynamic (MHD) equilibrium sequences and the points of linear ideal MHD instability is investigated imposing line-tied boundary conditions.

Generic Twistless Bifurcations [PDF]
We show that in the neighborhood of the tripling bifurcation of a periodic orbit of a Hamiltonian flow or of a fixed point of an area preserving map, there is generically a bifurcation that creates a ``twistless'' torus.

Travelling waves and their bifurcations in the Lorenz-96 model [PDF]
In this paper we study the dynamics of the monoscale Lorenz-96 model using both analytical and numerical means. The bifurcations for positive forcing parameter $F$ are investigated.

Study on the Compatibility of Multi-Bifurcations by Simulations of Pattern Formation
Bifurcation is considered the main mathematical mechanism for the formation of spatial self-organizing patterns in many studies. When bifurcation was initially defined, only the transition of the system from stable state to unstable state or from uniform

Bifurcation phenomena in magnetically confined toroidal plasmas
Bifurcation phenomena observed in turbulence and transport, in topology of magnetic field and MHD, and the interplay between turbulence and MHD bifurcation in magnetically confined toroidal plasmas are reviewed.
