When presented on its own without further elaboration, it served as the base condition against which all others could be contrasted.
In this setting, these objectively chosen representatives would be used as study sites in which long-term observations could be contrasted with those in the flagship landscapes.
That is to say, the reference device in this paper is an optimum performance, which could be used to contrast.
Nevertheless, Clayton and Schiffler suggested using local curvature which could be expressed as contrasts between relative risk (RR) of adjacent levels of a same variable so that the curvature in age i was: (3a) These identifiable contrasts determine the curvatures of secular trends, i.e. they represent a measure of the acceleration of the trend around age i.
In low-contrast conditions, more discrete visual dysfunctions may be revealed, which could be overlooked in high-contrast tests.
Therefore, the testing methodology outlined here is proposed as a pre-clinical testing tool, which could be used to compare and contrast existing stent designs and to develop novel stent designs.
That leaves the majority of the difference unexplained, which could be attributable to individual contrasts between twins' experiences, randomness or data that is erroneous or incomplete.
Accordingly, the result above proved that γ-alumina was successfully incorporated into the Catalyst II, which could be used as a contrast sample in this study.
A specific issue which could be addressed includes the contrast between ambiguity in the role, which was stressful for volunteers, and flexibility, which volunteers liked (although this may be being eroded by increasing formalisation of the role due to the introduction of management policies, such as job descriptions [ 44]).
