These results point to the persistence of subject-specific taxa whose frequency fluctuates between the time points.
The duration of visible persistence of subjects did not predict the time interval across which the subjects could integrate the shape cues, nor did it predict the rate of decline that was observed as the interval between display subsets was increased.
(The novel only transcends its time by dint of Orwell's genius, and the sad persistence of its subject; see North Korea, circa 2011).
In this case, we could conclude that Muller's ratchet is an unimportant factor for the persistence of the species subject to selfing, because insufficient time would have elapsed to have resulted in extinction by this process.
The theme of perfectionism and control issues surfaced in many instances among the data sets, concentrating and extending the driven persistence of some entrepreneurial subjects onto those around them, sometimes to an obsessive degree.
The remaining 4 patients with persistence of disease were subjected to a 'watch and wait' strategy (no treatment).
Issues about the persistence of people are the subject of an entire encyclopedia article in their own right (see the separate entry on personal identity), but it is worth highlighting points where the arguments discussed in earlier sections have special consequences for personal survival.
Frequencies of re-infection and persistence of HRV-C among subjects who contributed more than one positive sample over the study period were estimated by sequence comparisons in the VP4/VP2-encoding region.
Despite the low persistence of S. aureus colonization, subjects colonized with a toxigenic strain were found to display distributions of antibody titers skewed toward higher titers than other subjects.
Third, the persistence of MRSA colonization in the study subjects could not be determined and the incidence of subsequent MRSA infection could not be measured.
Similar results have been reported by Erwin & Herschenson [ 20], who assessed the duration of visible persistence by having subjects adjust the onset time of a second stimulus to the perceived offset time of a first stimulus.
