Bursting Point and beyond

Near-Threshold Bursting Is Delayed by a Slow Passage near a Limit Point

In a general model for square-wave bursting oscillations, we examine the fast transition between the slowly varying quiescent and active phases. In this type of bursting, the transition occurs at a saddle-node (SN) bifurcation point of the fast-variable subsystem when the slow variable is taken to be the bifurcation parameter. A critical case occurs when the SN bifurcation point is also a stead...

Different types of bursting calcium oscillations in non-excitable cells

In the paper different types of bursting Ca2þ oscillations are presented. We analyse bursting behaviour in four recent mathematical models for Ca2þ oscillations in non-excitable cells. Separately, regular, quasi-periodic, and chaotic bursting Ca2þ oscillations are classified into several subtypes. The classification is based on the dynamics of separated fast and slow subsystems, the so-called f...

ساخت ماکرو با هدف رهگیری دو پدیده چروکیدگی و ترکیدگی در فرآیند هیدروفرمینگ لوله

Determination of the optimum loading path (internal pressure- axial feeding) to restrict the Bursting, buckling and wrinkling through tube hydroforming process is necessary to produce an acceptable tube. In this paper, the wrinkling and fracture criteria are implemented to an finite element code devoted to the simulation of tube hydroforming processes. Using the ANSYS parametric design language...

Full system bifurcation analysis of endocrine bursting models.

Plateau bursting is typical of many electrically excitable cells, such as endocrine cells that secrete hormones and some types of neurons that secrete neurotransmitters. Although in many of these cell types the bursting patterns are regulated by the interplay between voltage-gated calcium channels and calcium-sensitive potassium channels, they can be very different. We investigate so-called squ...
