The mean ratio over all 270 orthologs for each lineage was applied as a relative rate correction to the Ks values for their respective taxa, and one-sided Mann–Whitney U tests of the rate-corrected duplication distributions and the distribution of ortholog divergences were used to assess if duplications occurred after lineage divergence.
The second part of the model comes from (3) log (θ i ) = μ + η i, where the relative risk (RR) in region i is given by θ i, μ represents the overall mean ratio over the entire region and the spatially correlated random effects are denoted by η i.
Computing the mean ratios of observed over expected CTCs (Supplementary Table S1), we determined a mean transfer efficiency of 85% (median 77%, standard deviation ± 49%).
Ratios are volume weighted Mean ratios of tumour rCBF over white matter rCBF were 1.7 ± 0.8 and 2.7 ± 1.5 for PET and PCT, respectively, including all patients.
In three ice-free seasons, the supra-permafrost discharge contributed a mean ratio of over 170% of the precipitation.
However, the mean ratio can vary over a wide range.
The mean ratio of grey over white matter was 2.2 ± 0.4 for PET and 2.5 ± 0.4 for PCT.
For each group and a number of genes, a centroid is defined as the mean ratio per gene over all samples in that group.
Differences in LS Geometric Mean Ratio morphine use over Days 1 3 from placebo were 0.66 (0.82, 0.85); 0.69 (0.56, 0.85); and 0.66 (0.81, 0.81) for etoricoxib 90 mg, etoricoxib 120 mg, and ibuprofen, respectively (p < 0.001 for etoricoxib vs. placebo).
We could show that after 11 cell division cycles in medium containing heavy isotope labeled Arg/Lys the mean ratio of heavy over light isotopes in the detected peptides changed more than 20 fold from 0.51 to 11.4 indicating that the majority of proteins had incorporated the heavy isotope amino acids (Additional file 1: Figure S2A).
