A Mechanistic Model for Partial Preferences
Theoretical Population Biology, 2000Classic prey optimal foraging model assumes that individual predators are globally omniscient; that is, they have exact knowledge of prey population densities in the environment. This study examines a spatially explicit individual-based model of a one-predator two-prey system where individual predators are assumed to be omniscient only locally, i.e ...

A mechanistic model of a PDGFRα+ cell
Journal of Theoretical Biology, 2016A novel platelet-derived growth factor receptor alpha-positive cell (PDGFRα(+)) has recently been identified as part of the purinergic inhibitory neural control mechanism in the gastrointestinal (GI) tract. The mechanism through which PDGFRα(+) cells mediate GI muscle relaxation has been found to be associated with the purine receptors P2Y1 and apamin ...

A mechanistic model of plasma filtration
Medical Engineering & Physics, 1998A model describing the sieving and transmembrane pressure behavior of plasma filtration is developed and numerically simulated. The model assumes a mechanistic criteria for particle passage through a membrane with cylindrical pores. The initial pore diameter distribution and porosity are assumed to be known.

Mechanistic Modeling of Carbonated Waterflooding
SPE Improved Oil Recovery Conference, 2018AbstractCO2 enhanced oil recovery is usually affected by poor sweep efficiency due to unfavorable mobility contrast between the injected CO2 and oil. To alleviate this problem, CO2 is added to the injected brine and transported in the reservoir by flood water.

Mechanistic Model of Wound Contraction
Journal of Surgical Research, 1993The interplay between cellular, biochemical, and biomechanical phenomena which result in wound contraction is examined with the aid of a mathematical model. The model accounts for fibroblasts repopulating the wound extracellular matrix (ECM) by a combination of migration and proliferation and, in the course of exerting traction forces associated with ...

Abstract The empiric models discussed heretofore have not explicitly incorporated knowledge of specific biological mechanisms, although in some cases, the form of the dose–response model may be motivated by theoretical considerations, such as the linear-quadratic cell-killing model used in radiobiology (see Chapter 6). In some instances,

Mechanistic biological modeling thrives
Science, 2016In their Perspective “Systems biology (un)certainties” (23 October 2015, p. [386][1]), P. D. W. Kirk et al. may give readers the impression that mathematical modeling and computer simulations of biological systems have fallen on hard times, owing to difficulties in measuring parameter values.

Mechanistic models for wind dispersal
Trends in Plant Science, 2006The growing need for ecological forecasts of, for example, species migration, has increased interest in developing mechanistic models for wind dispersal of seeds, pollen and spores. Analytical models are only able to predict mean dispersal distances, whereas sophisticated trajectory simulation models are able to incorporate rare wind conditions causing

A mechanistic damage model for ligaments
Journal of Biomechanics, 2017The accuracy of biomechanical models is predicated on the realism by which they represent their biomechanical tissues. Unfortunately, most models use phenomenological ligament models that neglect the behaviour in the failure region. Therefore, the purpose of this investigation was to test whether a mechanistic model of ligamentous tissue portrays ...

Mechanistic models are hypotheses: A perspective
Mathematical BiosciencesScience involves perceiving patterns (events that are repeated) in observations, hypothesizing causal explanations (underlying processes), and testing them. Mathematical models either describe or provide explanations for patterns. The equations of descriptive models have convenient mathematical properties while those of mechanistic ones correspond to ...
