But neither Duhem nor Quine was careful to systematically distinguish a number of fundamentally distinct lines of thinking about underdetermination that may be discerned in their works.
Our modeling approach allows us to systematically distinguish users who are linked to those who are not linked and study diffusion separately for each group.
In the second case they were systematically distinguished based on the results of the bouton population analyses (see previous section).
As described above, H2AK5, H4K16ac did not systematically distinguish Target and Non-target promoters: logically, therefore, cluster I. and II.
We have therefore used synonymous mutations to measure background LD [20], to systematically distinguish covariation from phylogenetic effects vs. other sources of covariation, independent of mathematical model assumptions.
Our study is the only one to date that has focused specifically on cell-autonomous silencing of transgenes and systematically distinguished between accumulation of primary and secondary siRNAs.
A key question is, how the large numbers of ncRNAs can be systematically distinguished from the complex mRNA population?
It may, therefore, be useful to systematically distinguish pure cases of either disorder from comorbid cases in future studies to better understand what is characteristic of each disorder.
The model successfully accounted for the behavioral data in that, an average cross-correlation based measure was able to systematically distinguish 'figure-present' from 'figure-absent' (or background) stimuli in a manner that mirrored the behavioral responses.
One of the most difficult problems in language comparison is to distinguish systematically between those words likely to be derived from a common protolanguage and the many words that are shared as a result of borrowing (and hence are not evidence of the languages themselves being related).
