Sentence examples for evolution ratio from inspiring English sources

The highest O2 evolution ratio is attained under 70% O2, along with the lowest CO2 evolution.

The separate evolution of H2 and O2 from water under solar light irradiation was successfully achieved using the Vis-TiO2/Ti/Pt which is hydrothermally treated for 5 h, while the H2 evolution ratio was 15 μmol h−1 in the early initial stage, corresponding to a solar energy conversion efficiency of 0.23%.

For each gene of interest, the presence of adaptive sequence evolution (ratio between synonymous [KS] and non-synonymous [KA] substitutions) was calculated between a pair of sequences (C. elegans and C. brigssae; C. elegans and C. remanei; C. briggsae and C. remanei) using PAL2NAL [57].

From Figure 5(a), we can see that the ratios of genomic evolution are different in different species, the maximum genomic evolution ratio is approximately equal to 0.9, and the minimum genomic evolution ratio is approximately equal to 0.6.

Rge(x) represents the value of genomic evolution in genome X, and std  Rge denotes the standard deviation of genomic evolution ratio in a set of species.

To test different proportions of rearrangement events, we also simulated datasets where the structural evolution ratios had a 2- and 5-fold increase.

Under a model of neutral evolution, the ratio of nonsynonymous to synonymous divergence is expected to equal the ratio of nonsynonymous to synonymous polymorphism.

Under neutral evolution, the ratio of replacement to silent mutations that are fixed between species should equal the ratio of replacement to silent polymorphisms within species [ 98].

This test posits that under a model of neutral evolution, the ratio of nonsynonymous to synonymous substitutions within a population is the same as the ratio of nonsynonymous to synonymous fixed differences between populations.

The principle idea underlying this test is the following: Given neutral evolution, the ratio of non-synonymous to synonymous polymorphisms Pn/Ps is expected to be the same as the ratio of non-synonymous to synonymous substitutions Dn/Ds [ 77].

'During human evolution, the ratio of omega-6 to omega-3 fatty acids in the diet was probably something like 1 1,' says Dr Alex Richardson, senior research fellow at the University Laboratory of Physiology, Oxford.
