Emergent complexity: what uphill analysis or downhill invention can not do
Dante R. Chialvo
In these notes we review emergent phenomena in complex systems, emphasizing ways to identify potential underlying universal mechanisms that generates complexity. The discussion is…
Solar forced Dansgaard-Oeschger events and their phase relation with solar proxies
H. Braun, P. Ditlevsen, D. R. Chialvo
North Atlantic climate during glacial times was characterized by large-amplitude switchings, the Dansgaard-Oeschger (DO) events, with an apparent tendency to recur preferably in mu…
Scale-free brain functional networks
Victor M. Eguiluz, Dante R. Chialvo, Guillermo A. Cecchi +2
Functional magnetic resonance imaging (fMRI) is used to extract {\em functional networks} connecting correlated human brain sites. Analysis of the resulting networks in different t…
Large Scale-Invariant Fluctuations in Normal Blood Cell Counts: A sign of criticality?
Carlos A. Perazzo, Elmer A. Fernandez, Dante R. Chialvo +1
All types of blood cells are formed by differentiation from a small self-maintaining population of pluri-potential stem cells in the bone marrow. Despite abundant information on th…
