Classical BO PVT models only allowed the "surface gas" pseudo-component to be part of both the reservoir gas and oil phases, but did not allow the "stock tank oil" pseudo-component to partake in the reservoir gas (Rv = 0).
Third, most static culture models only allow cells to be exposed to a constant concentration of a drug or chemical when testing for toxic properties.
The most likely reason for those negative results is that branch-site models only allow testing for positively selected codons using two different ω values, one for a given branch and a second for the rest of the tree.
The WINNER model only allows to apply linear antenna arrays with Q=1, whereas for the 3GPP 3D channel model, we consider a linear antenna array with Q=1 as well as a planar antenna array with Q=10 antenna elements in vertical direction.
Wada and Perron (2006) focus on the importance of changes in the level and slope of the trend, and as such, their model only allows the disturbances η t and υ t to be composed by a mixture of normals.
This discrepancy is related to the fact that the spherical model only allows for calculation of the self-tumor doses; however, for tumors located close to the organs with large uptakes (like the kidneys, liver, or spleen), the cross-organ contributions may be substantial.
Our pairwise model only allows identification of loci that are extremely divergent between Germany and other populations, but cannot identify loci that reveal evidence of local adaptation among non-German populations.
Conversely, a phantom model only allows limited conclusions with regard to the in vivo situation.
Finally, we have to acknowledge that the present model only allows median predictions while critical time-courses are clinically more relevant and therapy-limiting.
It is also important to consider that the fixed effect model only allows an inference about the studies included in the meta-analysis, whereas the random effects model allows an inference about the mean effect in a hypothetical population of studies if we can assume that the studies included in the meta-analysis constitute a random selection of studies from this hypothetical population.
