Coexisting coherent and incoherent domains near saddle-node bifurcation

, 2015
A common external forcing can cause a saddle-node bifurcation in an ensemble of identical Duffing oscillators by breaking the symmetry of the individual bistable (double-well) unit. The strength of the forcing determines the separation between the saddle

Fiber Track Length Gradients in the Avian Sound Localization Circuit Require Conduction Velocity Gradients to Maintain Isochronicity

Journal of Comparative Neurology, Volume 534, Issue 4, April 2026.
The gross anatomy of the sound localization circuit in the chicken brainstem was quantified with 3D reconstructions from serial sections and measurements of the interconnecting pathways. A rostral‐to‐caudal length gradient was measured in both the crossed dorsal cochlear track and the ipsilateral loop.

The Twisting Bifurcations of Double Homoclinic Loops with Resonant Eigenvalues

Abstract and Applied Analysis, 2013
The twisting bifurcations of double homoclinic loops with resonant eigenvalues are investigated in four-dimensional systems. The coexistence or noncoexistence of large 1-homoclinic orbit and large 1-periodic orbit near double homoclinic loops is given ...

Bifurcation of an SIRS Model with a Modified Nonlinear Incidence Rate

Mathematics, 2023
An SIRS epidemic model with a modified nonlinear incidence rate is studied, which describes that the infectivity is strong at first as the emergence of a new disease or the reemergence of an old disease, but then the psychological effect will weaken the ...

The saddle-node Hopf bifurcation with global reinjection

, 2003
A simultaneous saddle-node and Hopf bifurcation is a basic codimension-two local bifurcation of vector fields with a phase space of dimension at least three.

Numerical continuation of canard orbits in slow-fast dynamical systems

, 2009
A trajectory of a system with two clearly separated time scales generally consists of fast segments (or jumps) followed by slow segments where the trajectory follows an attracting part of a slow manifold. The switch back to fast dynamics typically occurs

Multi‐Stability of the Present‐Day Atlantic Meridional Overturning Circulation

WIREs Climate Change, Volume 17, Issue 2, March/April 2026.
There is much supporting evidence (freshwater export, paleo records, model hierarchy) that the present‐day AMOC is in a multi‐stable regime. ABSTRACT The Atlantic Meridional Overturning Circulation (AMOC) plays a key role in the climate system, especially in the global meridional heat transport.

The geometry of quadratic polynomial differential systems with a finite and an infinite saddle-node (A,B)

, 2013
The goal is to make a global study of the family QsnSN of all real quadratic polynomial differential systems which have a finite semi-elemental saddle-node and an infinite saddle-node formed by the collision of two infinite singular points.

A complex network perspective on brain disease

Biological Reviews, Volume 101, Issue 1, Page 364-399, February 2026.
ABSTRACT If brain anatomy and dynamics have a complex network structure as it has become standard to posit, it is reasonable to assume that such a structure should play a key role not only in brain function but also in brain dysfunction. However, exactly how network structure is implicated in brain damage and whether at least some pathologies can be ...
