Particle Statistics and Population Dynamics

open access: yes, 2004
We study a master equation system modelling a population dynamics problem in a lattice. The problem is the calculation of the minimum size of a refuge that can protect a population from hostile external conditions, the so called critical patch size ...

Adaptive dynamics in logistic branching populations [PDF]

open access: yes, 2007
We consider a trait-structured population subject to mutation, birth and competition of logistic type, where the number of coexisting types may fluctuate.

Evolutionary dynamics on any population structure

open access: yes, 2016
Evolution occurs in populations of reproducing individuals. The structure of a biological population affects which traits evolve. Understanding evolutionary game dynamics in structured populations is difficult. Precise results have been absent for a long

Modeling Best Practice Life Expectancy Using Gumbel Autoregressive Models

open access: yesRisks, 2021
Best practice life expectancy has recently been modeled using extreme value theory. In this paper we present the Gumbel autoregressive model of order one—Gumbel AR(1)—as an option for modeling best practice life expectancy. This class of model represents

Population Dynamics and Non-Hermitian Localization

open access: yes, 1999
We review localization with non-Hermitian time evolution as applied to simple models of population biology with spatially varying growth profiles and convection.

Treatment Decision‐Making Roles and Preferences Among Adolescents and Young Adults With Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Decision‐making (DM) dynamics between adolescents and young adults (AYAs) with cancer, parents, and oncologists remain underexplored in diverse populations. We examined cancer treatment DM preferences among an ethnically and socioeconomically diverse group of AYAs and their parents.

Entropy production of cyclic population dynamics

open access: yes, 2010
Entropy serves as a central observable in equilibrium thermodynamics. However, many biological and ecological systems operate far from thermal equilibrium. Here we show that entropy production can characterize the behavior of such nonequilibrium systems.

Novel Genetic Risk Factor Identified for L‐Asparaginase‐Induced Pancreatitis in Pediatric Patients With Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background L‐asparaginase is a critical component in treatment protocols for pediatric acute lymphoblastic leukemia. Acute pancreatitis reactions can necessitate delays and, in some cases, discontinuation of L‐asparaginase, which compromises outcomes.

The impact of COVID-19 on life expectancy across socioeconomic groups in Denmark

open access: yesPopulation Health Metrics
Background Denmark was one of the few countries that experienced an increase in life expectancy in 2020, and one of the few to see a decrease in 2021. Because COVID-19 mortality is associated with socioeconomic status (SES), we hypothesize that certain ...

Understanding Health Deterioration and the Dynamic Relationship between Physical Ability and Cognition among a Cohort of Danish Nonagenarians

open access: yesJournal of Aging Research, 2020
This study aims to determine how demographics, socioeconomic characteristics, and lifestyle affect physical and cognitive health transitions among nonagenarians, whether these transitions follow the same patterns, and how each dimension affects the ...
