First, to further probe the differences between the 'true' substitution process and standard models, we assembled 21 large protein sequence alignments and used two different methods to test if and how empirical frequencies at sites differ from those simulated under the standard JTT + F + Γ substitution model.
Advanced Cell Technology used two different methods to try to create human embryos.
It used two different methods of HMS-PP processing.
To test this hypothesis, we used two different methods to disrupt the function of the single bone-specific SIBLING gene spp1 in zebrafish.
In their experiments they used two different methods of gathering data, one dubbed the disappearance method and one the appearance method.
For measuring phylogenetic signal in thickness of calcareous eggshell layer and egg mass, we used two different methods: Blomberg's K, and Pagel's λ (phylosig from package 'phytools'53) both of which gave a significant phylogenetic signal for both traits (p ≤ 0.001).
We used two different methods for combining scores across judges.
8. Thomson actually used two different methods to determine the charge to mass ratio.
Since we used two different methods of interviews in this study, we found uncovered different levels of reality.
We used two different methods to predict seismic intensity at a target station from observed waveforms of an adjacent station in real time.
Each observer used two different methods for evaluation: (1) PET response criteria in solid tumors (PERCIST) 1.0 and (2) a qualitative approach.
