Condition-Dependent Neural Dimensions Progressively Shift during Reach to Grasp

open access: yesCell Reports, 2018
Summary: Neural population space analysis was performed to assess the dimensionality and dynamics of the neural population in the primary motor cortex (M1) during a reach-grasp-manipulation task in which both the reach location and the object being ...

How long do Red Queen dynamics survive under genetic drift? A comparative analysis of evolutionary and eco-evolutionary models

open access: yesBMC Evolutionary Biology, 2020
Background Red Queen dynamics are defined as long term co-evolutionary dynamics, often with oscillations of genotype abundances driven by fluctuating selection in host-parasite systems.

Dynamics of populations with changing rates: Generalization of the stable population theory

open access: yesTheoretical Population Biology, 1987
A general and complete exposition of the dynamics of populations with changing vital rates is given in the discrete time formulation. Results obtained are stronger than Lopez's or Hajnal's. In addition to the proof of existence of limits, an explicit expression for the age distribution is obtained by considering forward products of population ...

Dynamic Models of Infectious Disease Transmission in Prisons and the General Population [PDF]

open access: yesEpidemiologic Reviews, 2018
Incarcerated populations experience elevated burdens of infectious diseases, which are exacerbated by limited access to prevention measures. Dynamic models are used to assess the spread and control of diseases within correctional facilities and repercussions on the general population.

Continuous Monocyclic and Polycyclic Age Structured Models of Population Dynamics

open access: yesCommunication in Biomathematical Sciences, 2019
This paper focuses on the study of continuous age-structured models, or more general, physiologically structured models, which used for detailed and accurate study of population dynamics in many ecological, biological applications and medicine.

The Molecular Epidemiology and Transmission Dynamics of HIV Type 1 in a General Population Cohort in Uganda

open access: yesViruses, 2020
The General Population Cohort (GPC) in south-western Uganda has a low HIV-1 incidence rate (25 years (aOR = 1.52; 95% CI, 1.16–2.0) and being a resident in the GPC (aOR = 6.90; 95% CI, 5.22–9.21).

Understanding and forecasting population dynamics in changing arctic ecosystems [PDF]

open access: yes, 2020
Rapid environmental changes are currently occurring in the Arctic because of global warming. Arctic food webs can exhibit complex dynamics because of the prevalence of tight interactions between trophic levels.

The evolution of a population under recombination: how to linearise the dynamics [PDF]

open access: yes, 2002
A system of recursions is derived for the dynamics of an infinitely large population, evolving under a very general process of recombination, whereby an individual can inherit genes from an arbitrary number of parents, sampled independently from the ...
