The main interest in epidemic models stems from their use in uncovering certain qualitative features of epidemic processes. A deterministic model of a general epidemic in a population with an arbitrary number of separate population centers is presented. The mixing within each center is assumed to be homogeneous, and the usual threshold theorem holds for each population. The mixing between cente...

Population geneticists have shown that the effects of local extinction and recolonization on selectively neutral genetic diversity are sensitive to the number of individuals that migrate between groups. Here, we employ a spatially explicit metapopulation model to investigate the extent to which the effects of local extinction on selectively neutral cultural diversity and change are sensitive to...

This paper describes a fictional questionnaire intended to be completed by applicants to an intentional community devoted to gamifying all aspects of its members’ lives. This format was chosen as a plausible alternative to science fiction tropes that include the population of entire worlds or counties. It was also chosen because the historical motivations for creating intentional communities cl...

Variation in movement across time and space fundamentally shapes the abundance and distribution of populations. Although a variety of approaches model structured population dynamics, they are limited to specific types of spatially structured populations and lack a unifying framework. Here, we propose a unified network-based framework sufficiently novel in its flexibility to capture a wide varie...

This paper presents a discussion of coordination properties within populations of geospatially distributed embodied agents. We define two axes: interaction mechanisms and population diversity; and we present a new framework designed for exploring the relationship between values along these axes and the efficiency of solutions for a set of related tasks, e.g., foraging, resource allocation and a...

Previous results found for selection with antagonistic pleiotropy and discrete generations are extended to cases with overlapping generations. In order to do so, protected polymorphism conditions are found for monoecious and dioecious populations when the intrinsic rate of increase, or Malthusian parameter, is not too large in magnitude. Under such conditions, it is shown that recessive deleter...

Evolutionary games have been introduced by Maynard Smith and Price [1973] in the early 70’s with the aim to study the stability of populations in time. In the general model, a population consists of finitely many different types that interact randomly with each other, where each interaction leads to fitness payoffs for each of the types involved. Consequently, the population distribution over t...

The Common-pool resource (CPR) game is a social dilemma where agents have to decide how to consume a shared CPR. Either they each take their cut, completely destroying the CPR, or they restrain themselves, gaining less immediate profit but sustaining the resource and future profit. When no consumption takes place the CPR simply grows to its carrying capacity. As such, this dilemma provides a fr...

The article elaborates on the spatial disaggregation approach of the 1km population density grid created by the European Forum for Geostatistics in a defined study area where accurate population reference data are available. The paper presents an approach to disaggregate the population grid to target resolution of 100m and 500m respectively and describes the evaluation methodology. The resultin...

Model Evolution of Voltage over Time Consider a group of interacting populations of neurons. Equation 1 describes the evolution over time of the membrane voltages for the ith ensemble. Table 1 explains the remaining variables.
