Vibrational properties characterization of mouse embryo during microinjection [PDF]

open access: yes, 2013
To determine the vibration characteristics (natural frequencies and mode shapes) of a mouse embryo during microinjection the modal analysis is used. The spherical mouse embryo 60 μm in diameter is modeled as elastic finite elements biostructure ...

An in-host model of HIV incorporating latent infection and viral mutation [PDF]

open access: yes, 2015
We construct a seven-component model of the in-host dynamics of the Human Immunodeficiency Virus Type-1 (i.e, HIV) that accounts for latent infection and the propensity of viral mutation. A dynamical analysis is conducted and a theorem is presented which

Who Replaces Whom? Local versus Non-local Replacement in Social and Evolutionary Dynamics [PDF]

open access: yes, 2012
In this paper, we inspect well-known population genetics and social dynamics models. In these models, interacting individuals, while participating in a self-organizing process, give rise to the emergence of complex behaviors and patterns.

On the dynamics of a class of multi-group models for vector-borne diseases [PDF]

open access: yes, 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]

open access: yes, 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]

open access: yes, 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.

Do Longer Delays Matter? The Effect of Prolonging Delay in CTL Activation [PDF]

open access: yes, 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.

Transitions in active rotator systems: invariant hyperbolic manifold approach [PDF]

open access: yes, 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.

An Optimal Control Study for a Two‐Strain SEIR Epidemic Model With Saturated Incidence Rates and Treatment

open access: yesDiscrete Dynamics in Nature and Society, Volume 2025, Issue 1, 2025.
This work will study an optimal control problem describing the two‐strain SEIR epidemic model. The model studied is in the form of six nonlinear differential equations illustrating the dynamics of the susceptible and the exposed, the infected, and the recovered individuals.

Escort Evolutionary Game Theory

open access: yes, 2012
A family of replicator-like dynamics, called the escort replicator equation, is constructed using information-geometric concepts and generalized information entropies and diverenges from statistical thermodynamics.
