On the Validity of Neural Mass Models

open access: yesFrontiers in Computational Neuroscience, 2021
Modeling the dynamics of neural masses is a common approach in the study of neural populations. Various models have been proven useful to describe a plenitude of empirical observations including self-sustained local oscillations and patterns of distant ...

Impact Assessments of Transgenic cry1Ab Rice on the Population Dynamics of Five Non-Target Thrips Species and Their General Predatory Flower Bug in Bt and Non-Bt Rice Fields Using Color Sticky Card Traps

open access: yesJournal of Integrative Agriculture, 2013
A 2-yr field study was conducted to assess the effects of transgenic japonica rice (KMD1 and KMD2) with a synthetic cry1Ab gene from Bacillus thuingiensis Berliner on population dynamics and seasonal average densities of five thrips species including ...

Viability of Pentadesma in reduced habitat ecosystems within two climatic regions with fruit harvesting

open access: yesJournal of Biological Dynamics, 2022
Habitat loss and harvesting of non-timber forest products (NTFPs) significantly affect the population dynamics. In this paper, we propose a general mathematical modelling approach incorporating the impact of habitat size reduction and non-lethal ...

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 ...

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 ...

Linguistic dynamics: women versus general population in Reddit ADHD discussions

open access: yesAcademia Mental Health & Well-Being
Understanding how language reflects the experiences of individuals with attention-deficit/hyperactivity disorder (ADHD) is important for developing targeted support strategies.

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).

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.

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.
