Modeling complex systems [PDF]

open access: yesAgricultural Economics, 2010
AbstractEmpirical observations suggest that linear dynamics are not an adequate representation of ecological systems and that a realistic representation would require adoption of complex nonlinear dynamical systems with characteristics encountered in complex adaptive systems (CAS).

On modelling the immune system as a complex system [PDF]

open access: yesTheory in Biosciences, 2006
We argue that immune system is an adaptive complex system. It is shown that it has emergent properties. Its network structure is of the small world network type. The network is of the threshold type, which helps in avoiding autoimmunity. It has the property that every antigen (e.g.virus or bacteria) is typically attacked by more than one effector. This
