Fractal and multifractal analysis of PET-CT images of metastatic melanoma before and after treatment with ipilimumab
Christina-Marina Breki, Antonia Dimitrakopoulou-Strauss, Jessica Hassel +4
PET/CT with F-18-Fluorodeoxyglucose (FDG) images of patients suffering from metastatic melanoma have been analysed using fractal and multifractal analysis to assess the impact of m…
Controlling Chimera States - The influence of excitable units
Thomas Isele, Johanne Hizanidis, Astero Provata +1
We explore the influence of a block of excitable units on the existence and behavior of chimera states in a nonlocally coupled ring-network of FitzHugh-Nagumo elements. The FitzHug…
Multi-chimera states in the Leaky Integrate-and-Fire model
N. D. Tsigkri-DeSmedt, J. Hizanidis, P. Hoevel +1
We study the dynamics of identical leaky integrate-and-fire neurons with symmetric non-local coupling. Upon varying control parameters (coupling strength, coupling range, refractor…
Chimera states in population dynamics: networks with fragmented and hierarchical connectivities
Johanne Hizanidis, Evangelia Panagakou, Iryna Omelchenko +3
We study numerically the development of chimera states in networks of nonlocally coupled oscillators whose limit cycles emerge from a Hopf bifurcation. This dynamical system is ins…
