Although parts of population models, e.g. the simulation of developmental stages or the simulation of survival, may be rather easy to understand, the existence and interaction of many such 'modules' make models more difficult to explain.
This bias in expression is highly robust and consistent across different tissues and developmental stages, and simulations demonstrate that these results are not due to ascertainment bias alone (Table S4; see File S1 for details).
Quite probably – in the simulations showing developmental system drift the phenotype used is one or more gene expression levels, 18, 47, 48 which is as applicable to unicellular systems as development, and may be more tractable in simpler, experimental evolution systems.
The model depends on a set of initial conditions to start the developmental stage of the simulation using a randomly generated initial state vector.
Population pharmacokinetic modelling and developmental approach enabled to perform simulations, which showed that continuous infusion was the most adapted dosing regimen, for children over 1 month of age.
The developmental time in all our simulations is based on experimental observations [24], [39].
In simulations of dynamical developmental processes such as pattern formation, one should also expect robust behaviour within a certain extent in the model [ 20].
Our simulation suggests that developmental 'double dissociations' can be especially misleading, since developmental disorders can produce contrasting differential deficits in a single integrated mechanism, but the application of standard neuropsychological reasoning would interpret this pattern as evidence for a two-part system. 1.
Finally, a conceptual model is developed, based on field survey and numerical simulations, to summarize the developmental processes operating within the intertidal zone in response to CER.
Thus, using a carefully constructed fitness function and with target patterns representing the typical complexity of a developmental CRM, we hoped that our simulations will provide meaningful insights into what it takes to evolve an enhancer.
