Phase lag in epidemics on a network of cities

G. Rozhnova, A. Nunes, A. J. McKane

We study the synchronisation and phase-lag of fluctuations in the number of infected individuals in a network of cities between which individuals commute. The frequency and amplitu…

Stochastic oscillations in models of epidemics on a network of cities

G. Rozhnova, A. Nunes, A. J. McKane

We carry out an analytic investigation of stochastic oscillations in a susceptible-infected-recovered model of disease spread on a network of cities. In the model a fraction $f…

Stochastic effects in a seasonally forced epidemic model

Ganna Rozhnova, Ana Nunes

The interplay of seasonality, the system's nonlinearities and intrinsic stochasticity is studied for a seasonally forced susceptible-exposed-infective-recovered stochastic model. T…

Fluctuations and oscillations in a simple epidemic model

Ganna Rozhnova, Ana Nunes

We show that the simplest stochastic epidemiological models with spatial correlations exhibit two types of oscillatory behaviour in the endemic phase. In a large parameter range, t…

Coherence thresholds in models of language change and evolution: the effects of noise, dynamics and network of interactions

J M Tavares, M M Telo da Gama, A Nunes

A simple model of language evolution, proposed in \cite{K_N}, is characterized by a pay-off in communicative function, and by an error in learning, that measures the accuracy in la…

Pair Approximation Models for Disease Spread

Jerome Benoit, Ana Nunes, Margarida Telo da Gama

We consider a Susceptible-Infective-Recovered (SIR) model, where the mechanism for the renewal of susceptibles is demographic, on a ring with next nearest neighbour interactions, a…
