PURPOSE To evaluate intersession and intrasession repeatability of aberration data obtained with a new visual simulator based on adaptive optics, which includes a Hartmann-Shack aberrometer (Adaptive Optics Vision Analyzer; Voptica S.L., Murcia, Spain). METHODS Thirty-one healthy right eyes were included in the study. To evaluate intrasession repeatability, three consecutive measurements with...

AIMS The study aimed to: a) determine reliability of an instrumented speculum designed for measuring intravaginal closure pressure, and b) compare findings with a comparable device reported in the literature. The goal of these new devices is to reduce subjectivity, improve precision, and acknowledge reliability issues in quantifying levator ani closure force acting on the vagina. METHODS The ...

The random amplified polymorphic DNA (RAPD) technique is often criticized because it usually shows low levels of repeatability; thus it can generate spurious bands. These problems can be partially overcome by rigid laboratory protocols and by performing repeatability tests. However, because it is expensive and time-consuming to obtain genetic data twice for all individuals, a few randomly chose...

pressure and inter-beat interval variability in man. Apart from that the topic of the study is interesting and important, the paper contains some terminological inconsistencies which seriously undermine implications of research and thus, credibility of the conclusions made by the Authors. It is not uncommon to find studies with inconsistent terminology and definitions, with some terms being def...

We present Provenance-To-Use (PTU), a tool that minimizes computation time during repeatability testing. Authors can use PTU to build a package that includes their software program and a provenance trace of an initial reference execution. Testers can select a subset of the package’s processes for a partial deterministic replay—based, for example, on their compute, memory and I/O utilization as ...

The number of minimally invasive cardiological interventions has increased over the last few years and therefore computer based training systems find growing interest. They offer a better learning schedule compared to traditional master-apprentice models due to the repeatability of the learning situation and the possibility to learn individual tasks. Below we present the research system CathI t...

BACKGROUND AND PURPOSE For more widespread clinical use advanced imaging methods such as relative cerebral blood volume must be both accurate and repeatable. The aim of this study was to determine the repeatability of relative CBV measurements in newly diagnosed glioblastoma multiforme by using several of the most commonly published estimation techniques. MATERIALS AND METHODS The relative CB...
