We found evidence of positive selection at the four brush-border enzymes, indicating stronger selective pressure compared with transporters and taste receptors.
In this approximation, a target mutation of selection coefficient σ is subject to interference by stronger selective sweeps at a total rate V > = ∫ σ ∞ d σ ′ V drive.
Our observation of stronger selective constraints in long introns suggests that functional elements subject to purifying selection may be concentrated within long introns.
Smallpox was more likely to kill children before they reached reproductive age, thus creating a stronger selective pressure.
These results suggest that, despite their high average degree, EMFs, unlike regular hubs, are under stronger selective pressure to maintain a stable secondary structure.
Ultimately, I hope to convince you that, contrary to popular belief, living in water appears to impose stronger selective pressures on these organisms than does living on land.
These factors must be taken into account when assessing the present findings, as those with higher IQs would be expected to have stronger selective attention abilities, and the observed group differences are subsumed in part by possible general cognitive delays.
Less faithful copying demands stronger selective forces if adaptive variation is not to be lost.
The bigger the ST value, the stronger the root controls Na+ and promotes transport of K+ to shoot, indicating a stronger selective transport capacity of the root.
In summary, CTL responses that exerted stronger selective pressure occurred earlier, proliferated faster, and decayed faster.
This logic is also found in autoregulated polycistrons which points at stronger selective forces acting on this type of regulation than on the specific genetic implementation.
