Transcritical riddling in a system of coupled maps [PDF]

open access: yes, 2001
The transition from fully synchronized behavior to two-cluster dynamics is investigated for a system of N globally coupled chaotic oscillators by means of a model of two coupled logistic maps.

Bifurcation Behavior Analysis in a Predator-Prey Model

open access: yesDiscrete Dynamics in Nature and Society, 2016
A predator-prey model is studied mathematically and numerically. The aim is to explore how some key factors influence dynamic evolutionary mechanism of steady conversion and bifurcation behavior in predator-prey model.

A Survey of SIR‐Based Differential Epidemic Models for Control and Security Against Malware Propagation in Computer Networks

open access: yesSECURITY AND PRIVACY, Volume 9, Issue 1, January/February 2026.
ABSTRACT Unarguably, malware and their variants have metamorphosed into objects of attack and cyber warfare. These issues have directed research focus to modeling infrastructural settings and infection scenarios, analyzing propagation mechanisms, and conducting studies that highlight optimized remedial measures.

Arnol′d tongues arising from a grazing-sliding bifurcation [PDF]

open access: yes, 2009
The Neımark–Sacker bifurcation, or Hopf bifurcation for maps, is a well-known bifurcation for smooth dynamical systems. At this bifurcation a periodic orbit loses stability, and, except at certain “strong” resonances, an invariant torus is born.

Mathematical Modeling of the Dynamics of Female Genital Schistosomiasis as a Risk Factor to Cervical Cancer

open access: yesAbstract and Applied Analysis, Volume 2026, Issue 1, 2026.
Female genital schistosomiasis (FGS), caused by chronic infection with Schistosoma haematobium, represents a significant but neglected gynecological condition that affects approximately 56 million women in sub‐Saharan Africa. This parasitic disease manifests itself through chronic inflammation and tissue damage in the female genital tract, leading to ...

Assessing the Potential Effect of Antiretroviral Therapy Disruption on HIV Transmission Dynamics

open access: yesAbstract and Applied Analysis, Volume 2026, Issue 1, 2026.
Background Sustained access to antiretroviral therapy (ART) is central to controlling human immunodeficiency virus (HIV) transmission and reducing AIDS‐related morbidity and mortality. Recent funding uncertainties and policy shifts, however, threaten the continuity of ART provision in several high‐burden settings.

Some New Investigations on the Dynamic Biocompetitive Ecological Model (DBEM): A Nonautonomous Framework for Planetary Overshoot

open access: yesComplexity, Volume 2026, Issue 1, 2026.
Seven of nine planetary boundaries have been transgressed and anthropogenic mass now exceeds all living biomass, yet existing collapse models assume ecological regeneration—contradicting tipping‐point evidence—while integrated assessment models rely on smooth damage functions that preclude irreversibility.

A Fractional‐Order Complexity Framework for Misinformation Propagation With Fact‐Checking Saturation and Social Vulnerability Dynamics

open access: yesComplexity, Volume 2026, Issue 1, 2026.
Misinformation spreads through communities in ways that resemble infectious diseases, but existing mathematical models often miss three real‐world complexities: People remember past information (memory effects), some folks are more easily fooled than others (vulnerability), and fact‐checkers can get overwhelmed during big outbreaks (saturation).

A Dynamical Analysis of Supply Chain Systems Under a Dynamic Game Framework Considering Green Technology Innovation

open access: yesDiscrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.
A dynamic model of a green supply chain, comprising two manufacturers incorporating green technology innovation and one product component supplier, was constructed based on a gradient adjustment mechanism. The dynamic behavior of the system was analyzed through stability analysis of equilibrium points and bifurcation conditions, using parameter ...
