Sub-spreading events limit the reliable elimination of heterogeneous epidemics

Kris V. Parag
2021 Journal of the Royal Society Interface  
We show that sub-spreading events, i.e. transmission events in which an infection propagates to few or no individuals, can be surprisingly important for defining the lifetime of an infectious disease epidemic  ...  and hence its waiting time to elimination or fade-out, measured from the time-point of its last observed case.  ...  These characteristics make the GW process unsuitable for the analysis of elimination statistics [7] , especially when the generation time distribution is known (a) to be non-degenerate, (b) to have long  ...

Spontaneous brain activity as a source of ideal1/fnoise

Paolo Allegrini, Danilo Menicucci, Remo Bedini, Leone Fronzoni, Angelo Gemignani, Paolo Grigolini, Bruce J. West, Paolo Paradisi
2009 Physical Review E  
We convert the coincidences into a diffusion process with three distinct rules that can yield the same only in the case where the coincidences are driven by a renewal process.  ...  We establish that the time interval between two consecutive renewal events driving the coincidences has a waiting-time distribution with inverse power-law index Ϸ 2 corresponding to ideal 1 / f noise.  ...  Proving that the brain's 1 / f noise emerges from the renewal condition would provide a solid foundation for the science of socioneurophysiological processes.  ...
