The pace of evolution across fitness valleys [PDF]

open access: yes, 2009
How fast does a population evolve from one fitness peak to another? We study the dynamics of evolving, asexually reproducing populations in which a certain number of mutations jointly confer a fitness advantage.

Comparing Levels of Fitness of Police Officers between Two United States Law Enforcement Agencies Journal of Sports Medicine and Physical [PDF]

open access: yes, 2018
BACKGROUND: The general physical task demands of law enforcement may suggest that police Officers are of similar fitness levels across cities, states and countries.OBJECTIVE: To investigate whether fitness levels of police Officers from two different ...

No association between passive material property and cross-sectional area in human hamstring

open access: yesJournal of Physical Fitness and Sports Medicine, 2018
The passive material properties of a muscle, as evaluated by shear or Young’s modulus, can vary depending on the muscle cross-sectional area (CSA), since intramuscular compositions such as adipose tissue and connective tissue change with muscle ...

The relative fitness of drug-resistant Mycobacterium tuberculosis: a modelling study of household transmission in Peru. [PDF]

open access: yes, 2017
The relative fitness of drug-resistant versus susceptible bacteria in an environment dictates resistance prevalence. Estimates for the relative fitness of resistant Mycobacterium tuberculosis (Mtb) strains are highly heterogeneous and mostly derived from

The epigenetic clock is correlated with physical and cognitive fitness in the Lothian Birth Cohort 1936 [PDF]

open access: yes, 2015
Background: The DNA methylation-based 'epigenetic clock' correlates strongly with chronological age, but it is currently unclear what drives individual differences. We examine cross-sectional and longitudinal associations between the epigenetic clock and

Metastable Evolutionary Dynamics: Crossing Fitness Barriers or Escaping via Neutral Paths?

open access: yes, 1999
We analytically study the dynamics of evolving populations that exhibit metastability on the level of phenotype or fitness. In constant selective environments, such metastable behavior is caused by two qualitatively different mechanisms. One the one hand,

Pulmonary Dysfunction Is Associated With Sleep Study Abnormalities in Children With Sickle Cell Disease: A Multicenter Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.
