Codimension-one bifurcation analysis and chaos of a discrete prey–predator system

open access: yesJournal of Taibah University for Science
In this paper, we explore local dynamics at equilibrium points, the existence of bifurcation sets and codimension-one bifurcation analysis of a discrete prey–predator system with Holling type-II functional response.

Fluid Inertia Rewires Flow Graphs and Selects Late Solute Paths in a Rough Fracture

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Graph models of fractured media commonly vary edge weights while retaining one directed topology. We tested this assumption in a measured three‐dimensional rough fracture using steady Navier‐Stokes flow, flux‐closure recirculation zones, directed voxel graphs, and conservative graph transport.

Stability and Cycles in a Cobweb Model with Heterogeneous Expectations [PDF]

open access: yes
We investigate the dynamics of a cobweb model with heterogeneous beliefs, generalizing the example of Brock and Hommes (1997). We examine situations where the agents form expectations by using either rational expectations, or a type of adaptive ...

Existence of Singularity Bifurcation in an Euler-Equations Model of the United States Economy: Grandmont was Right [PDF]

open access: yes
: Grandmont (1985) found that the parameter space of the most classical dynamic general-equilibrium macroeconomic models are stratified into an infinite number of subsets supporting an infinite number of different kinds of dynamics, from monotonic ...

Bifurcation and hybrid control of a discrete eco-epidemiological model with Holling type-III.

open access: yesPLoS ONE
In this paper, a three dimensional discrete eco-epidemiological model with Holling type-III functional response is proposed. Boundedness of the solutions of the system is analyzed.

Flip-flop MRI sequence acquisition.

open access: yes, 2018
From left to right: flip sequence, flop sequence and substracted image (flip − flop). Experimental conditions: flowing water in a 3mm inner diameter silicone tube, vmean = 120μm/s, TR = T1/2 = 1.23s, TE = 15ms, FOVREAD = 20mm, FOVPHASE = 20mm, NREAD ...

Some Applications of Bifurcation Formulae to the Period Maps of Delay Differential Equations [PDF]

open access: yes, 2005
Our purpose is to present some applications of the bifurcation formulae derived in [13] for periodic delay differential equations. We prove that a sequence of Neimark-Sacker bifurcations occurs as the parameter increases.

Non-Robust Dynamic Inferences from Macroeconometric Models: Bifurcation Stratification of Confidence Regions [PDF]

open access: yes
Grandmont (1985) found that the parameter space of the most classical dynamic models are stratified into an infinite number of subsets supporting an infinite number of different kinds of dynamics, from monotonic stability at one extreme to chaos at the ...

Bifurcation Curves in Discontinuous Maps [PDF]

open access: yes
Several discrete-time dynamic models are ultimately expressed in the form of iterated piecewise linear functions, in one or two-dimensional spaces. In this paper we study a one-dimensional map made up of three linear pieces which are separated by two ...

Stability and bifurcation analysis of a modified chemostat model

open access: yesDemonstratio Mathematica
In this work, we derive a discrete-time chemostat model from a continuous-time population model using the forward Euler method. We first determine the model’s fixed points and analyze their local stability.
