Spreading Processes on Networks

Roles of Nodes, Links, and Hyperlinks

Spreading processes are ubiquitous in nature and society, from the diffusion of information in social platforms to the spread of diseases within populations. Many real-world systems can be represented as networks, where a piece of information or a disease spreads along links conn ...
Nodal spreading influence is the capability of a node to activate the rest of the network when it is the seed of spreading. Combining nodal properties (centrality metrics) derived from local and global topological information respectively has been shown to better predict nodal in ...
This paper aims to understand to what extent the amount of drug (e.g., cocaine) trafficking per country can be explained and predicted using the global shipping network. We propose three distinct network approaches, based on topological centrality metrics, Susceptible-Infected-Su ...
Progress has been made in how to suppress epidemic spreading on temporal networks via blocking all contacts of targeted nodes or node pairs. In this work, we develop contact blocking strategies that remove a fraction of contacts from a temporal (time evolving) human contact netwo ...
