Stochastic Spatial Metapopulation Modelling of HPAI Control and Poultry Restocking on Jolly Island
Hammed O. Fatoyinbo, Indranil Ghosh, Parul Tiwari +3
Highly pathogenic avian influenza (HPAI) outbreaks require rapid control during active transmission and evidence-based decisions on the safe restocking of depopulated farms. We dev…
Collective Phase Reorganization and Cluster Synchronization in Networks of Coupled Gumowski--Mira Maps
Hammed Olawale Fatoyinbo, Indranil Ghosh
We investigate the collective dynamics of networks composed of diffusively coupled Gumowski-Mira maps and analyze how modifications in the intrinsic dynamics of the local oscillato…
Spatiotemporal dynamics and ecological risk factors of highly pathogenic avian influenza A(H5N1) in Canadian wildlife: A One Health surveillance analysis
Hammed Olawale Fatoyinbo, Hoyeon Jeong
Highly pathogenic avian influenza A(H5N1) has expanded geographically and ecologically, affecting wild birds, mammalian wildlife, domestic animals, and humans. Wildlife surveillanc…
Stochastic Modelling and Analysis of Within-Farm Highly Pathogenic Avian Influenza Dynamics in Dairy Cattle
Parul Tiwari, Malavika Smitha, Hammed Olawale Fatoyinbo
Highly pathogenic avian influenza (HPAI) has expanded its host range with recent detections in dairy cattle, raising critical concerns regarding within-herd persistence and cross-s…
Disrupting the scammer lifecycle: A dynamically-consistent numerical analysis of a compartment model for scam-victim dynamics
Y. O. Tijani, I. Ghosh, S. D. Oloniiju +1
Online deception and financial scams represent a pervasive threat in the digital age, yet a quantitative analysis and understanding of their propagation is lacking. This study intr…
A mathematical model of HPAI transmission between dairy cattle and wild birds with environmental effects
H. O. Fatoyinbo, P. Tiwari, P. O. Olanipekun +1
Highly pathogenic avian influenza (HPAI), particularly H5N1, poses an increasing threat at the wildlife--livestock--environment interface, with recent detections in dairy cattle mo…
Time series analysis of coupled slow-fast neuron models: From Hurst exponent to Granger causality
Indranil Ghosh, Hammed O. Fatoyinbo, Sishu S. Muni
We perform time series analysis of small networks where every node is the slow-fast version of the denatured Morris--Lecar neuron proposed by Schaeffer and Cain. We choose popular…
Fractional order induced bifurcations in Caputo-type denatured Morris-Lecar neurons
Indranil Ghosh, Hammed Olawale Fatoyinbo
We set up a system of Caputo-type fractional differential equations for a reduced-order model known as the {\em denatured} Morris-Lecar (dML) neurons. This neuron model has a struc…
Dynamical properties of a small heterogeneous chain network of neurons in discrete time
Indranil Ghosh, Anjana S. Nair, Hammed Olawale Fatoyinbo +1
We propose a novel nonlinear bidirectionally coupled heterogeneous chain network whose dynamics evolve in discrete time. The backbone of the model is a pair of popular map-based ne…
On the higher-order smallest ring star network of Chialvo neurons under diffusive couplings
Anjana S. Nair, Indranil Ghosh, Hammed O. Fatoyinbo +1
We put forward the dynamical study of a novel higher-order small network of Chialvo neurons arranged in a ring-star topology, with the neurons interacting via linear diffusive coup…
A synopsis of the non-invertible, two-dimensional, border-collision normal form with applications to power converters
Hammed Olawale Fatoyinbo, David J. W. Simpson
The border-collision normal form is a canonical form for two-dimensional, continuous maps comprised of two affine pieces. In this paper we provide a guide to the dynamics of this f…

Indranil Ghosh, Sishu Shankar Muni, Hammed Olawale Fatoyinbo
We perform a numerical study on the application of electromagnetic flux on a heterogeneous network of Chialvo neurons represented by a ring-star topology. Heterogeneities are reali…
Dynamical Model of Mild Atherosclerosis: Applied Mathematical Aspects
