Evolutionary dynamics in structured populations [PDF]
Philosophical 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.

NONLINEAR RELAXATION IN POPULATION DYNAMICS [PDF]
Scaling and Disordered Systems, 2002 We analyze the nonlinear relaxation of a complex ecosystem composed of many interacting species. The ecological system is described by generalized Lotka-Volterra equations with a multiplicative noise. The transient dynamics is studied in the framework of the mean field theory and with random interaction between the species. We focus on the statistical

Using stochastic dynamic programming to support weed management decisions over a rotation [PDF]
, 2009 This study describes a model that predicts the impact of weed management on the population dynamics of arable weeds over a rotation and presents the economic consequences.

Julius-Kühn-Archiv, 2016 Weed species easily establish in crops with a similar life cycle. Especially mono-cropping provides best conditions for such weeds. In maize this is true for Echinochloa crus-galli, which is a C4 plant and one of the worst weeds worldwide.

Dynamic computation of population protocols [PDF]
2010 17th International Conference on Telecommunications, 2010 Population protocols provide theoretical foundations for mobile tiny device networks in which global behavior emerges from a set of simple interactions between anonymous agents. The works in this area mostly focus on studying the computational power of the model.

Population Dynamics of Bacterial Persistence
PLoS ONE, 2013 Persistence is a prime example of phenotypic heterogeneity, where a microbial population splits into two distinct subpopulations with different growth and survival properties as a result of reversible phenotype switching. Specifically, persister cells grow more slowly than normal cells under unstressed growth conditions, but survive longer under stress

Age determination and growth in the Tench Tinca tinca (L.) in Lake Jorkjenn, southern Norway
Fauna Norvegica, 1985 The age and growth of tench Tinca tinca (L.) collected from Lake Jorkjenn, southern Norway was investigated. Otoliths and opercular bones were found more suitable for age determination than scales.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...
