Effects of behaviour change on HFMD transmission
Journal of Biological Dynamics, 2023 We propose a hand, foot and mouth disease (HFMD) transmission model for children with behaviour change and imperfect quarantine. The symptomatic and quarantined states obey constant behaviour change while others follow variable behaviour change depending

On the dynamics of a class of multi-group models for vector-borne diseases [PDF]
, 2015 The resurgence of vector-borne diseases is an increasing public health concern, and there is a need for a better understanding of their dynamics. For a number of diseases, e.g.

Modeling and analysis of random and stochastic input flows in the chemostat model [PDF]
, 2019 In this paper we study a new way to model noisy input flows in the chemostat model, based on the Ornstein-Uhlenbeck process. We introduce a parameter β as drift in the Langevin equation, that allows to bridge a gap between a pure Wiener process, which is

Beyond clustering: mean-field dynamics on networks with arbitrary subgraph composition [PDF]
, 2014 Clustering is the propensity of nodes that share a common neighbour to be connected. It is ubiquitous in many networks but poses many modelling challenges.

On variable-order hybrid FracInt Covid-19 mathematical model: optimal control approach
Arab Journal of Basic and Applied Sciences, 2023 An optimal control problem for the variable-order fractional-integer mathematical model of vaccination Covid 19 is presented in this research, where the order of the derivatives varies during the course of the time interval, becoming fractional or ...

Does a population with the highest turnover coefficient win competition?
, 2017 We consider a discrete time competition model. Populations compete for common limited resources but they have different fertilities and mortalities rates. We compare dynamical properties of this model with its continuous counterpart.

Do Longer Delays Matter? The Effect of Prolonging Delay in CTL Activation [PDF]
, 2010 The activation of a specific immune response takes place in the lymphoid organs such as the spleen. We present here a simplified model of the proliferation of specific immune cells in the form of a single delay equation.

International Journal of Differential Equations, Volume 2025, Issue 1, 2025.Gompertz dynamics offer significant applications for the growth of invasive species, cancer modeling, optimal harvesting policies, sustainable yield, and maintaining population levels due to its pattern formation in low‐density cases. This paper examines a widely applicable nonhomogeneous diffusive Gompertz law with zero Neumann boundary conditions ...

Information Geometry and Evolutionary Game Theory [PDF]
, 2009 The Shahshahani geometry of evolutionary game theory is realized as the information geometry of the simplex, deriving from the Fisher information metric of the manifold of categorical probability distributions.

Transitions in active rotator systems: invariant hyperbolic manifold approach [PDF]
, 2011 Our main focus is on a general class of active rotators with mean field interactions, that is globally coupled large families of dynamical systems on the unit circle with non-trivial stochastic dynamics.
