Here, we consider transcription and expression (T) edges only by looking at the subgraph and defining the subset of genes that are regulated by at least one edge in A potential regulator r can be any node in V that is either a gene, protein family, complex, microRNA, or chemical.
Recently, CD146 or MCAM was used by Sacchetti et al to define the subset of stromal fibroblasts that contribute to a stem cell niche.
We defined the subsets by whether the mean distance of a word to other words is larger or smaller than the median mean distance.
Focusing on the "well behaved" or conserved gene changes alone would not only impede the choice of sample collection, but would also make conclusions and findings more subjective by selecting only those parameters that define the subsets of a population containing these conserved changes.
The first paper begins by defining set, subset, etc., in ways that would be largely acceptable now.
Since selection of the optimal combination of candidate features is a combinatorial problem, we first reduce the size of the search space by defining a predetermined subset of features used in all feature-selection iterations.
We also explored the "chip extension" procedure, an approach allowing to increase the reliability of heterologous hybridizations by defining subset of probes less likely to be prone to expression artifacts.
Moreover, the use of certain biomarkers may provide diagnostic benefit by defining subsets of a disease that may have a distinct response profile to one or another drug.
To maximize system lifetime, we propose to exploit sensor spatial redundancy by defining subsets of sensors active in different time periods, to allow sensors to save energy when inactive.
If the two lineages evolved in parallel, then their phylogenetic trajectories are identical in the morphological space defined by the subset of characters involved.
