LEARNING, EVOLUTION AND POPULATION DYNAMICS [PDF]

open access: yesAdvances in Complex Systems, 2008
We study a complementarity game as a systematic tool for the investigation of the interplay between individual optimization and population effects and for the comparison of different strategy and learning schemes. The game randomly pairs players from opposite populations. It is symmetric at the individual level, but has many equilibria that are more or

Population Dynamics in River Networks [PDF]

open access: yesJournal of Nonlinear Science, 2019
Natural rivers connect to each other to form networks. The geometric structure of a river network can significantly influence spatial dynamics of populations in the system. We consider a process-oriented model to describe population dynamics in river networks of trees, establish the fundamental theories of the corresponding parabolic problems and ...

Stratification in health and survival after age 100: evidence from Danish centenarians

open access: yesBMC Geriatrics, 2021
Background The existence of a super-select group of centenarians that demonstrates increased survivorship has been hypothesized. However, it is unknown if this super-select group possesses similar characteristics apart from extreme longevity.

Evolutionary dynamics in structured populations [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2010
Abstract Evolutionary dynamics shape the living world around us. At the centre of every evolutionary process is a population of reproducing individuals. The structure of that population affects evolutionary dynamics. The individuals can be molecules, cells, viruses, multicellular organisms or humans.

Modeling and forecasting sex differences in mortality: a sex-ratio approach

open access: yesGenus, 2018
Female and male life expectancies have converged in most industrialized societies in recent decades. To achieve coherent forecasts between females and males, this convergence needs to be considered when forecasting sex-specific mortality.

Mapping adolescent sexual and reproductive health research in sub-Saharan Africa: protocol for a scoping review

open access: yesBMJ Open, 2020
Introduction Previous studies have attempted to review the vast body of evidence on adolescent sexual and reproductive health (ASRH), but none has focused on a complete mapping and synthesis of the body of inquiry and evidence on ASRH in sub-Saharan ...

Potential gains in life expectancy by reducing inequality of lifespans in Denmark: an international comparison and cause-of-death analysis

open access: yesBMC Public Health, 2018
Background Reducing lifespan inequality is increasingly recognized as a health policy objective. Whereas lifespan inequality declined with rising longevity in most developed countries, Danish life expectancy stagnated between 1975 and 1995 for females ...
