Sentence examples for nested subsets of from inspiring English sources

Third, we examined to what extent species assemblages of species-poor habitat islands are nested subsets of those of species-rich ones.

The seed bank composition changed with time since fragmentation started, triggered by the deterministic loss of grassland species, generating nested subsets of the seed banks of semi-natural grasslands.

It can therefore be inferred that factor 2 subsumes nested subsets of biotic and abiotic variables that directly affect the (mean) fitnesses of species' populations in different guilds.

In order to study sensitivity to sample size (number of observations), we sample without replacement from the original gene expression data nested subsets of size 10, 20, 30,..., N, where N is the number of samples in the dataset.

In order to check that this is the case, we used three nested subsets of sequences for each of the three protein families and calculated the resulting reproducibility and accuracy (see "Methods").

As an additional measure of the composition of the median ant faunas, we tested whether depauperate medians tended to have a nested subset of species found at more diverse medians.

While exposure assessment may add substantial costs limiting feasibility, future health studies, which use a combination of measurements in a nested subset of health assessment households together with exposure models, are needed to minimize exposure misclassification, thereby strengthening the evidence for association while providing relevant exposure-response information.

In a propensity score matched-pairs analysis that used a nested subset of the cohort (N = 706), attributable length of stay attributable to CDAD was 2.8 days, attributable readmission at 180 days was 19.3%, and attributable death at 180 days was 5.7%.

According to [28] there are four steps to implement the structural risk minimization (see section Structural risk minimization), of which the first step is to choose a class of functions with hierarchy of nested subsets in ordered of the complexity.

One possible approach for dealing with residual heterogeneity is to subdivide the main classes further, such as into Types 1A, 1B, 2A, 2B, etc, effectively classifying samples in multiple tiers to establish nested subsets, within each of which the cases and controls are more homogeneous and better balanced.

However the definition of an appropriate sequence of nested subsets remains an open issue.
