Three actively constrained regions as a function of the main disturbances, namely, the fuel and steam feed rates, are identified; each region represents different sets of active constraints.
Overall, the findings of this study provide the necessary insight and motivation to the remote sensing community, particularly in resource constrained regions, to shift towards embracing various texture metrics obtained from the readily-available and cheap multispectral Landsat-8 OLI sensor.
Since HIV-1 proteins other than p24 may also contain functionally and structurally constrained regions, we investigated if there is a general correlation between the relative hazard of HLA alleles and the tendency to target constrained parts of the HIV-1 proteome.
Another advantage of the ICA approach is that it requires no prior assumptions regarding the number or locations of active neural sources in a given paradigm (although of course there is often prior knowledge that constrains regions of interest, as in the present case).
However, a high degree of sequence divergence between the predicted products of each ORF (the level of sequence identity varies from approximately 40% to 60% identity in amino acid sequence alignments, although the identity is locally higher in functionally constrained regions, Table S1) is observed.
Underrepresented oligonucleotides, however, seem to be gradually eliminated by a molecular drag emanating from the combined effects of mutation, the negative effect of the oligonucleotide and some of its mutated forms on the fitness of the carrier, and selection against changes in the functionally constrained regions of the genome.
Evolutionarily constrained regions were detected essentially as described previously [ 12].
We then used this HMM to predict constrained regions to which we refer as mitoPopCons elements.
The bioinformatics procedures used for calling SNPs have their own assumptions (including that the underlying genome is diploid) which may unduly constrain regions marked as potentially heterogeneous.
When purifying selection is weak and mutation is biased, constrained regions can even evolve faster than neutral sequences and thus can appear to be under positive selection.
