Thus, for that screening test, a larger percent of participants with true disease go on to have their disease status correctly ascertained, and observed in the study, than for the other screening test.
For Rorty, warrant is a "sociological matter, to be ascertained by observing the reception of [a speaker's] statement by her peers" (1993: 449).
Hence, the performance of the system can only be ascertained by observing the results by probing the exposed interfaces which include the globe system performance and the external resources.
The presence of MAP specific DNA was ascertained by observing IS900 specific amplicons after PCR was performed as described previously [3].
Comparative morphological analyses within a phylogenetic framework help to unravel the complex patterns of skeletal morphological evolution [ 8- 10] and are essential for 1) assessing evolutionary trends [ 10, 11], 2) inferring changes in rates of evolution [ 12], and 3) ascertaining whether observed similarities result from common descent or are acquired independently [ 8, 13].
On the other hand, it is difficult to ascertain whether changes observed were indeed associated with cancer or due to variations in genetic backgrounds when using non-isogenic in vitro cell models.
Both MRC5 and U2OS cell lines were subsequently used in parallel for most experiments to ascertain if any observed effects required the more reliable cell cycle checkpoints of primary cells (MRC5) and thus were not recapitulated in transformed cell lines such as the U2OS line that has stable p53- and pRb-dependent checkpoints but is defective for p16INK [24], [24].
Cells below the subepidermal layer could also be observed, ascertaining that this method is sufficient to obtain enough depth of focus to analyze the entire subepidermal layer in situ.
In order to ascertain that the observed signals were not originating from the annealing of random non-specific sequences, specificity validation was conducted through a simple detection test using species- and gene-specific primers and by gene-specific microarray hybridization.
The total number of prevalent diabetes cases in each province was estimated as the sum of: (1) observed cases ascertained from hospital discharge abstracts only, (2) observed cases ascertained from claims of FFS physicians, (3) predicted cases for NFFS physicians.
Evaluation of model performance is discussed in a forthcoming section but can, in part, be ascertained by superimposing mean observed data onto the simulation results (i.e., plasma- or tissue-specific concentration time data).
