Non-perturbative heterogeneous mean-field approach to epidemic spreading in complex networks
Non-perturbative heterogeneous mean-field approach epidemic spreading complex networks
2011/9/9
Since roughly a decade ago, network science has focussed among others on the problem of how the spreading of diseases depends on structural patterns. Here, we contribute to further advance our underst...
Understanding how far information, behaviors, or pathogens spread in social networks is an important problem, having implications for both predicting the size of epidemics, as well as for planning e e...
Impact of Heterogeneous Human Activities on Epidemic Spreading
Epidemic Spreading, Human Dynamics, Inter-Event Time Distribution, Susceptible-Infected Model, Heterogeneity
2011/9/2
Recent empirical observations suggest a heterogeneous nature of human activities.The heavy-tailed inter-event time distribution at population level is well accepted,while whether the individual acts i...

A computer mediated social network is a modern information system where data is generated, distributed, evaluated and accumulated. It is important to understand how the topology of the network affects...

Beam-spreading and topological charge of vortex beams propagating in a turbulent atmosphere
Vortex beams Turbulent atmosphere Beam-spreading Orbital angular momentum
2013/7/3
We theoretically and experimentally investigate the beam-spreading of a vortex beam propagating in a turbulent atmosphere. It is found that the vortex beam is less affected by turbulence than a non-vo...

The Spreading Width Calculation of Giant Resonances with a Semi-Microscopic Approach
Giant Resonance Statistical Multistep Compound Theory Random Phase Approximation Spreading Width
2010/10/13
We have proposed a semi-microscopic approach to calculate the two particles - two holes (2p¡2h) spreading width of giant resonances. Our proposal has been based in a hybrid method that implement...
Stochastic Dynamics of Coupled Systems and Damage Spreading
Stochastic Dynamics Coupled Systems Damage Spreading
2010/10/28
We study the damage spreading in the one-dimensional Ising model by means of the stochastic dynamics resulting from coupling the system and its replica by a family of algorithms that interpolate betwe...
