The model assumes that frequency-selective activations occur primarily at borders between ACFs that share common frequency tuning.
The standard selective sweep model assumes the following: 1) At fixation, all copies of the favored variant are identical by descent and 2) the favored variant begins as a new mutation (Maynard Smith 1976).
The selective phase model assumes that cohesive interactions between FG repeats cross-link them into a sieve-like FG hydrogel, whose mesh size sets an upper size limit for passive NPC passage (Ribbeck and Görlich, 2001; Frey and Görlich, 2007).
Lambert et al. (2002) argued that this region of the mt-genome is not under strong selective pressure, so our model assumes random drift among the N x segregating genomes.
Similarly, the model assumed random, non-selective Symbiodinium loss; selective loss may also follow a Gaussian distribution, but more studies are needed to test this premise.
In brief, the branch-specific model assumes variation among branches, but not among sites; the site-specific model assumes variation of selective pressure among sites, but not among branches.
This model assumes that there is an optimal value of the covariate and that there are some selective penalties associated with extreme values [ 77].
Our model assumes that the expected waiting times depend on the values of three parameters, namely the selective advantage coefficient s, the transform factor a and the initial mutation rate µ0.
The model assumes that processing is largely feedforward but also is influenced by a feedback loop, governed by attention, inducing selective enhancement of signals being processed.
