The choice of these coordinate axes was motivated by a previous modeling study [19] that suggested that the (o+i) pool of ERG potassium channels was the appropriate slow variable for a fast/slow analysis.
In the case of postmating isolation induced by bidirectional CI, a previous model has shown that premating isolation mechanisms are likely to be selected for [ 30].
This model can be modified to incorporate other cells in the 3D scaffold, like microglia, blood-borne macrophages, and necrotic cellular debris and by combining with a previous model using cells suspended in a CSF-like solution, like astrocytes [ 14], microglia, bacteria, red blood cells or platelets, tumor cells, or necrotic cellular debris.
It enhances a previous model by the authors, which is based on a discrete-continuous concept and is suitable for depths of burial at which 'arching' can develop.
In this study, a RWH site allocation method was improved from a previous model, by introducing the dam wall height as evaluation parameter.
In the present paper, the continuum lumping methodology is applied to the hydrocracking of Fischer Tropsch waxes (n-paraffins), extending a previous model by Laxminarasimhan et al. (1996).
The cavern sizes measured are compared with the fluids' rheology by a simple extension of a previous model, and good agreement is found.
This approach assumes a single collective duplication move as in a previous model by Presser and coworkers [ 14] and is not concerned with asymptotic properties as were other models present in the literature [ 20].
Thirdly, in taking a recommended decision analytical approach, 15 we refined the structure of a previous model by allowing prosthesis failure to occur in the first year after the primary hip replacement or after revision surgery.
In addition, a previous model by Edmunds et al. [ 12] had estimated the potential cost-effectiveness of vaccination prior to the availability of data on the clinical efficacy of such a vaccine.
