The susceptible-infected-susceptible (SIS) model is a canonical model for emerging disease outbreaks. Such outbreaks are naturally modeled as taking place on networks. A theoretical challenge in network epidemiology is the dynamic correlations coming from that if one node is infected, then its neighbors are likely to be infected. By combining two theoretical approaches-the heterogeneous mean-field theory and the effective degree method-we are able to include these correlations in an analytical…

Susceptible-infected-recovered epidemics in random networks with population awareness.
Results show that the local awareness can suppress significantly the epidemic spreading on complex networks via raising the epidemic threshold and such effects are closely related to the formulation of awareness functions.
Robustness and fragility of the susceptible-infected-susceptible epidemic models on complex networks
We analyze two alterations of the standard susceptible-infected-susceptible (SIS) dynamics that preserve the central properties of spontaneous healing and infection capacity of a vertex increasing
Modeling the spread of multiple contagions on multilayer networks
Effective approach to epidemic containment using link equations in complex networks
The approach allows a scheme for the containment of epidemics based on deactivating the most important links in transmitting the disease, and promises to be an effective tool to maintain functionality of networks while controlling the spread of diseases, such as disease spread through air transportation networks.
Contact-Based Model for Epidemic Spreading on Temporal Networks
A contact-based model to study the spreading of epidemics by means of extending the dynamic message-passing approach to temporal networks and derives an analytical expression for the epidemic threshold on temporal networks to demonstrate the feasibility of this method on empirical data.
Toward a generalized theory of epidemic awareness in social networks
We discuss the dynamics of a susceptible-infected-susceptible (SIS) model with local awareness in networks. Individual awareness to the infectious disease is characterized by a general function of


It is still unknown whether there are families of tight knots whose lengths grow faster than linearly with crossing numbers, but the largest power has been reduced to 3/z, and some other physical models of knots as flattened ropes or strips which exhibit similar length versus complexity power laws are surveyed.
