On the other hand, the Levenshtein distance does not consider the time alignment of the two sequences, and may result in misleading evaluation in the case that two phonetic subsequences that are not co-occurring in time are aligned by mistake.
Thus presumably a large number of these species are not co-occurring for the first time in central Pennsylvania, and many of them have likely been living there together for several centuries.
Complementary sequences must not co-occur in the same phylogeny, so that one has to choose one strand from each pair.
PCLD is a progressive disorder characterized by many (>20/liver) fluid-filled liver cysts that might or might not co-occur with autosomal dominant PCKD (Torres et al., 2007).
However, a critical feature distinguishing true recombinants from PCR chimeras is that the latter should always co-occur with both parental sequences in the same amplicon, whereas true recombinants may or may not co-occur with one or both parental sequences.
Moreover, A flagellum does not co-occur with A narutobiei.
Most species/clades did not co-occur, with the exception of M. bravo B1 and B2 (Fig. S2).
NO3− and NH4+ essentially do not co-occur, indicating that the dominant source of NH4+ at these sites likely is not dissimilatory reduction of NO3− to NH4+.
Because MYC amplification is a possible confounder to the miRNA identified as associated with TSG across cancer types, we checked to ensure that mutation of the 8 TSG identified, across cancer types, does not co-occur significantly with MYC amplification.
Variables subject to an order restriction, for instance Y ≤ X, have a bivariate distribution over a non-rectangular joint domain that entails a non-null and potentially large structural relation even if the variables show no association (in the sense that particular ranges of values of X do not co-occur with particular ranges of values of Y).
These do not co-occur with lexical items but rather replace them.
