However, one assumption of the GAB model for vapor sorption in glassy polymers is inconsistent with the fact that there are two species of sorption sites as the CDMS model assumes.
It wasn't until her postdoctoral training at the University of California at Berkeley, however, that Lamason found her model systems: two species of bacteria called Rickettsia parkeri and Listeria monocytogenes.
As a means to address this question, we evaluated a novel approach by creating spatial niche models for two species of psammophilic lizards.
Indeed, the model distinguishes only two species of inorganic nitrogen (largely corresponding to ammonium and nitrate) but includes other species, like nitrite, not considered in this study.
The cystic fibrosis (CF) field is the beneficiary of five species of animal models that lack functional cystic fibrosis transmembrane conductance regulator (CFTR) channel.
We can also consider a more general case, in which we have four species of mtDNA in our model: wildtype reproducing (m1), mutant reproducing (m2), wildtype sterile (m3) and mutant sterile (m4).
In this paper, we formulate an nonautonomous impulsive population model with nonlinear interspecific competitive terms, and introduce the random perturbation of the birth rates of two species into this model.
We built a model using four species of endemic passerine birds in order to evaluate the case in an Atlantic Forest area, a biodiversity hotspot.
The gene models were further filtered by running OrthoMCL39 with the protein models from six species of mollusks (Crassostrea gigas, Pinctada fucata, Lottia gigantea, Aplysia californica, Biomphalaria glabrata, and Octopus bimaculoides) and sequences that could be clustered with these molluscs were retained.
The three Plesiosaurus models represents three species of marine reptile, P. macrocephalus, P. dolichoderius and P. hawkinsii, from the Jurassic of England.
