A celebrated and controversial hypothesis suggests that some biological systems—parts,
aspects, or groups of them—may extract important functional benefits from operating at the …

In recent years the research community has accumulated overwhelming evidence for the
emergence of complex and heterogeneous connectivity patterns in a wide range of …

The propagations of diseases, behaviors and information in real systems are rarely
independent of each other, but they are coevolving with strong interactions. To uncover the …

Concepts shape the interpretation of facts. One of the most popular concepts in systems
neuroscience is that of 'hierarchy'. However, this concept has been interpreted in many …

Abstract Models of epidemic spreading on complex networks have attracted great attention
among researchers in physics, mathematics, and epidemiology due to their success in …

Extensive cooperation among unrelated individuals is unique to humans, who often sacrifice
personal benefits for the common good and work together to achieve what they are unable …

Universality is a powerful concept, which enables making qualitative and quantitative
predictions in systems with extensively many degrees of freedom. It finds realizations in …

Hallmarks of criticality, such as power-laws and scale invariance, have been empirically
found in cortical-network dynamics and it has been conjectured that operating at criticality …

Microbial communities are enigmatically diverse. We propose a novel view of processes
likely affecting microbial assemblages, which could be viewed as the Great American …

This book discusses the study and analysis of the physical aspects of social systems and
models, inspired by the analogy with familiar models of physical systems and possible …
