Hamiltonian dynamics of the SIS epidemic model with stochastic fluctuations

GM Nakamura, AS Martinez - Scientific reports, 2019 - nature.com
Empirical records of epidemics reveal that fluctuations are important factors for the spread
and prevalence of infectious diseases. The exact manner in which fluctuations affect …

Markovian approach to tackle the interaction of simultaneous diseases

D Soriano-Paños, F Ghanbarnejad, S Meloni… - Physical Review E, 2019 - APS
The simultaneous emergence of several abrupt disease outbreaks or the extinction of some
serotypes of multistrain diseases are fingerprints of the interaction between pathogens …

Large deviations of random walks on random graphs

F Coghi, J Morand, H Touchette - Physical Review E, 2019 - APS
We study the rare fluctuations or large deviations of time-integrated functionals or
observables of an unbiased random walk evolving on Erdös-Rényi random graphs, and …

Generalized optimal paths and weight distributions revealed through the large deviations of random walks on networks

R Gutiérrez, C Pérez-Espigares - Physical Review E, 2021 - APS
Numerous problems of both theoretical and practical interest are related to finding shortest
(or otherwise optimal) paths in networks, frequently in the presence of some obstacles or …

[HTML][HTML] Rare slips in fluctuating synchronized oscillator networks

J Hindes, IB Schwartz - Chaos: An Interdisciplinary Journal of …, 2018 - pubs.aip.org
We study rare phase slips due to noise in synchronized Kuramoto oscillator networks. In the
small-noise limit, we demonstrate that slips occur via large fluctuations to saddle phase …

Weighted-ensemble network simulations of the susceptible-infected-susceptible model of epidemics

E Korngut, O Vilk, M Assaf - Physical Review E, 2025 - APS
The presence of erratic or unstable paths in standard kinetic Monte Carlo simulations
significantly undermines the accurate simulation and sampling of transition pathways. While …

General formulation of long-range degree correlations in complex networks

Y Fujiki, T Takaguchi, K Yakubo - Physical Review E, 2018 - APS
We provide a general framework for analyzing degree correlations between nodes
separated by more than one step (ie, beyond nearest neighbors) in complex networks. One …

Epidemic extinction in networks: insights from the 12 110 smallest graphs

P Holme, L Tupikina - New Journal of Physics, 2018 - iopscience.iop.org
We investigate the expected time to extinction in the susceptible-infectious-susceptible
model of disease spreading. Rather than using stochastic simulations, or asymptotic …

Enhancement of large fluctuations to extinction in adaptive networks

J Hindes, IB Schwartz, LB Shaw - Physical Review E, 2018 - APS
During an epidemic, individual nodes in a network may adapt their connections to reduce
the chance of infection. A common form of adaption is avoidance rewiring, where a …
