To investigate the relative magnitudes of these signal variations, a model for the response of the biosensor must be formulated.
Penalised likelihood imposes constraints on rate variation combining a model allowing substitution rate variation among branches with a roughness penalty that mediates rate changes from branch to branch.
It aims at investigating the impact of variations in uncorrelated inputs on the variation of a model output and ranking the importance of the inputs.
To address the extent and genetic basis of variation in a model adaptive trait, we have examined flowering-time variation in a set of C. rubella accessions.
With the data that such experiments generate to hand, what can the natural genetic variation of a model organism tell us?
This idea is a variation on a model in use in several countries, the best known being TERI's Lighting a Billion Lives campaign in India.
This would include a historical investigations unit, an independent commission on information retrieval and an implementation and reconciliation group – a variation of a model that first began to take shape as part of a consultation process that began in 2007 and reported two years later.
The Mystery Plant Adaptation activity described above let the students observe the dramatic effect of introducing inherited variation into a model with a spatially inhomogeneous environment.
Each fairy variation was a model of decorum and refinement, with each woman blossoming through the steps.
