The fitness increase is generated by major beneficial mutations that spread through the population until saturation (the near-stasis phase); subsequent beneficial mutations will lead to a renewed fitness increase (Lenski and Travisano 1994, see also review by Elena and Lenski 2003).
Author's response: Probably, there are some theories of punctuational evolution based on different rate of mutations or different stringency of reparation processes during evolutionary stasis and during phase of accelerated evolution.
The bank said: Since the height of the financial crisis, volumes in the UK residential market have been characterised by three distinct phases: stasis (2009/2012), recovery (2013 onwards) and, more recently, a fall, likely driven by pre-election caution and some impact from tougher bank lending criteria.
This technique allows improved characterization of turbulent flow and CSF stasis relative to phase-contrast techniques.
One hypothesis states that neurons die through 'phase stasis'; in late S phase, G2 and M phase, mitochondrial proliferation takes place, exposing neurons with defective control over their cell cycle even more to the damaging effects of ROS [ 90].
It can be divided into four overlapping pathologic phases: prefreeze, freeze thaw, vascular stasis, and a later ischemic phase (18).
Even though those LTT plots were shown to be indistinguishable from those produced by a model where rates are constant but interrupted by a phase of stasis [ 72], they are still very different from those produced by typical diversity-dependent models such as in our results.
Hopefully this would allow readers to evaluate for themselves the raw data for the existence of two distinct phases of "stasis" vs. "rapid turnover".
We, however, consider the qualitative connotation of the term to be less arbitrary and use "protracted" as a relative term, indicating an evolutionary process with phases of stasis or even reversal.
Tumour dormancy generally describes a phase of apparent stasis in tumour growth and is mechanistically subdivided into two models.
