A Primer on Quantitative Modeling

2015
Caenorhabditis elegans is particularly suitable for obtaining quantitative data about behavior, neuronal activity, gene expression, ecological interactions, quantitative traits, and much more. To exploit the full potential of these data one seeks to interpret them within quantitative models. Using two examples from the C.

A quantitative model of Phycomyces phototropism

Journal of Theoretical Biology, 1977
Abstract A quantitative model accounting for phototropism in the wild type and in behavioural mutants of Phycomyces is described. Photomecisms (changes in the sporangiophore's growth velocity in response to changes in light intensity) are produced by a system composed of two sets of linear transducers separated by an adaptation mechanism, the first ...

Quantitative modeling of dielectrophoretic traps

Lab on a Chip, 2006
We present quantitative modeling software for simulating multiple forces acting on a single particle in a microsystem. In this paper, we focus on dielectrophoretic (DEP) trapping of single cells against fluid flow. The software effectively models the trapping behavior for a range of particles including beads, mammalian cells, viruses, and bacteria.

A quantitative model of diffusion bioassays

Journal of Theoretical Biology, 1979
Abstract A quantitative description is given of the well-known experiment of detecting biological activity of a chemical by putting a droplet of it at the center of a petri-dish containing a bacterial lawn in an agar gel. The model used for the quantitative description relates activity exclusively to the space-time concentration profile of the ...

Mathematical modelling and quantitative methods

Food and Chemical Toxicology, 2002
The present review reports on the mathematical methods and statistical techniques presently available for hazard characterisation. The state of the art of mathematical modelling and quantitative methods used currently for regulatory decision-making in Europe and additional potential methods for risk assessment of chemicals in food and diet are ...

Quantitative modeling of segmental duration

Proceedings of the workshop on Human Language Technology - HLT '93, 1993
In natural speech, durations of phonetic segments are strongly dependent on contextual factors. Quantitative descriptions of these contextual effects have applications in text-to-speech synthesis and in automatic speech recognition. In this paper, we describe a speaker-dependent system for predicting segmental duration from text, with emphasis on the ...
