The Effects of Evolutionary Adaptations on Spreading Processes in Complex Networks

, 2019
A common theme among the proposed models for network epidemics is the assumption that the propagating object, i.e., a virus or a piece of information, is transferred across the nodes without going through any modification or evolution.

Activity driven modeling of time varying networks [PDF]

, 2012
Network modeling plays a critical role in identifying statistical regularities and structural principles common to many systems. The large majority of recent modeling approaches are connectivity driven.

Community Structure in Jazz

, 2003
Using a database of jazz recordings we study the collaboration network of jazz musicians. We define the network at two different levels. First we study the collaboration network between individuals, where two musicians are connected if they have played ...

Feedback-induced stationary localized patterns in networks of diffusively coupled bistable elements

, 2013
Effects of feedbacks on self-organization phenomena in networks of diffusively coupled bistable elements are investigated. For regular trees, an approximate analytical theory for localized stationary patterns under application of global feedbacks is ...

Immunization strategies for epidemic processes in time-varying contact networks [PDF]

, 2013
Spreading processes represent a very efficient tool to investigate the structural properties of networks and the relative importance of their constituents, and have been widely used to this aim in static networks.
