Computer systems research spans sub-disciplines that include embedded systems, programming languages and compilers, networking, and operating systems. Our contention is that a number of structural factors inhibit quality systems research. We highlight some of the factors we have encountered in our own work and observed in published papers and propose solutions that could both increase the produ...
Purpose. To determine the intraexaminer repeatability and interexaminer reproducibility of tear meniscus height (TMH) and noninvasive Keratograph tear breakup time (NIKBUT) measurements obtained with the Keratograph 5M (K5M) in a sample of healthy and dry eye populations. Methods. Forty-two patients with dry eye disease (DED group) and 42 healthy subjects (healthy group) were recruited in this ...
Purpose. To assess the repeatability and reproducibility of ocular biometry and intraocular lens (IOL) power measurements obtained by ophthalmology residents using an AL-Scan device, a novel optical biometer. Methods. Two ophthalmology residents were instructed regarding the AL-Scan device. Both performed ocular biometry and IOL power measurements using AL-Scan, three times on each of 128 eyes,...
In the present study, we investigated the relationship between blood pressure (BP) and pulse transit time (PTT) and evaluated the accuracy of the PTT-based cuffless BP estimation on 14 normotensive subjects. Least-squares regression was used to estimate BP in the first test and a repeatability test carried out half year later. BP in the repeatability test was also estimated using the regression...
The 2015 Text REtrieval Conference (TREC) introduced the concept of ‘Open Runs’ in response to the increasing focus on repeatability of information retrieval experiments. An Open Run is a TREC submission backed by a software repository such that the software in the repository reproduces the system that created that exact run. The ID of the repository was captured during the process of submittin...
One major assumption for endocrine studies is that hormone titers are consistent within an individual so that if hormone titers are low relative to the cohort on one day, they are relatively low compared to the cohort on other days. This is an especially important assumption for most field studies where researchers may have access to an individual animal only once. We used a laboratory study wi...
John S. Villarrubia András E. Vladár Michael T. Postek National Institute of Standards and Technology Gaithersburg, Maryland 20899 Abstract. The ability of a critical dimension scanning electron microscope CD-SEM to resolve differences in the widths of two lines depends on the instrument’s measurement repeatability and any sampledependent biases. The dependence of repeatability and bias on eigh...
The objective of this study was to evaluate the genotypic stability of agronomic traits in hybrids of Panicum maximum. Hybrids originating from the crosses between two sexual parents and cultivars Mombasa and Tanzania were evaluated in an incomplete-block design. Evaluated traits were total dry matter, leaf dry matter, stem dry matter, percentage of leaves, and leaf:stem ratio. These traits wer...
OBJECTIVE The aim was to study how the measurement error affects the repeatability of mismatch negativity (MMN) measurements. METHODS Event-related potentials (ERPs) to changes in sound frequency, location, intensity, duration, and composition were recorded five times during 1-3 weeks from 13 healthy adults using a multi-feature MMN paradigm. The accumulation of MMN was modeled empirically wi...
Animal personalities are ubiquitous across the animal kingdom and have been shown both to influence individual behaviour in the social context and to be affected by it. However, little attention has been paid to possible carryover effects of social conditions on personality expression, especially when individuals are alone. Here we investigated how the recent social context affected the boldnes...
