Structure of the beta-amiliod protein, responsible of degenerative
diseases of the nervous system such as Parkinson and sclerosis.
Vectorial and scalar topological defects in the vector complex
Ginzburg-Landau equation. Vectorial defects are surrounded by large
domains while scalar defects accumulate at domain borders.
Exitable chemical reaction in a fluid stirred by a chaotic open flow. The figure shows the activator spatial distribution from a computer simulation of the process. When leaving the system, the substance traces filaments on top of the 'unstable manifold of the chaotic saddle', a fractal region produced by the fluid flow.
Complex networks allow us to represent the interactions in a complex system. For the brain functional network displayed in the figure, nodes represent small voxels of the brain, while the links indicate when two voxels are related functionally.
