With multiple specimens and multiple tests on those specimens, the volume of data collected by PERCH therefore presents analytic challenges in interpreting detection of multiple pathogens and distinguishing infection from causation.
The crack-resistance curve (R-curve) of this BMG has been obtained from fatigue pre-crack samples, employing standard "single-specimen" and "multiple-specimen" techniques.
When multiple and different foci were included in one specimen and thus multiple diagnoses were obtained, those of the most severe grades were regarded as final diagnoses of the main lesions.
Deformation was stopped at the yield point in the pre-failure phase (Kovári and Tisa 1975) to avoid damage of the specimen and permit multiple tests.
A single tissue specimen was provided for 27 patients, and multiple specimens (2 3, collected from different anatomic sites or at different times) were provided for five patients.
Model simulations are compared with results from experiments using cruciform specimens, of single and multiple fiber polymer-matrix composites.
Specimens with single and multiple grooves of tens of micrometers in width were fabricated on silicon wafers.
For this analysis, all serum specimens from these case-patients were considered independent samples, and multiple specimens obtained at different times during the acute phase of illness of the same patient were included in the temporal analysis.
Specimens and datasets are well maintained, sample sizes are large, specimen background information is recorded, and multiple incidence assays and potential supplemental tests have been measured on the same specimens.
Monkeys were euthanized 3 days after challenge and multiple specimens from tissues were collected for pathological, virological and immunological tests.
Single and multiple specimens at the antrum alone, at the body alone, or in combination of antrum and body had been described and applied (Table 4).
