Regular grids or lattices are frequently used to study ecosystems, for observations,
experiments and simulations. The regular rectangular or square grid is used more often than …

Background and objective Many countries around the world experienced a high increase in
the number of COVID-19 cases after a few weeks of the first case, and along with it …

Chagas disease is a major health concern in South and Central America. In the absence of

More than half the global population are already urban, and the UN and other organisations
expect this share to rise in future. However, some researchers argue that the future of cities …

We study the spreading of contagious diseases in a population of constant size using
susceptible-infective-recovered (SIR) models described in terms of ordinary differential …

Abstract Currently, SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) is a
major worldwide public-health problem. Here, its propagation is modeled by using a …

Disease spreading models need a population model to organize how individuals are
distributed over space and how they are connected. Usually, disease agent (bacteria, virus) …

A simple susceptible–infectious–removed epidemic model for smallpox, with birth and death
rates based on historical data, produces oscillatory dynamics with remarkably accurate …

Susceptible-infective-removed (SIR) models are commonly used for representing the spread
of contagious diseases. A SIR model can be described in terms of a probabilistic cellular …

The spread of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) is here
investigated from an epidemic model considering four pathways of person-to-person …
