This study investigates the inter-trial variability of saccade trajectories observed in five rhesus macaques (Macaca mulatta). For each time point during a saccade, the inter-trial variance of eye position and its covariance with eye end position were evaluated. Data were modeled by a superposition of three noise components due to 1) planning noise, 2) signal-dependent motor noise, and 3) signa...

BACKGROUND The management of distal radial fractures is guided by the interpretation of radiographic findings. The aim of this investigation was to determine the intra- and inter-observer reliability of eight traditionally reported anatomic radiographic parameters in adults with an acute distal radius fracture. METHODS Five observers participated. All were routinely involved in making treatme...

conclusions inter-rater accuracy could be improved at middle grades using renal ultrasonography (usg), which could promote communication between different specialists. results the intraclass correlation coefficient (icc) values ranging from 0.86 to 0.89 reflected good reliability. the lowest agreement was associated with middle grades (iii and iv). a marked difference in sensitivity was observe...

to examine metal content of dandelion plants in relation to environmental metal levels,concentrations of cd, hg and pb were analyzed in plant parts (leaves and roots) and soil samples from fivesites in the city of brno (czech republic), differentially impacted by pollution. soils and plants werecollected mid-april 2011. atomic absorption spectrometry was used to determine concentrations of thes...

conclusions this persian version of the fim can be used as a valid, reliable, and replicable instrument for research and rehabilitation purposes in tbi patients. results the inter-rater reliability was acceptable on admission and at discharge (icc = 0.779 to 0.895). the internal consistency of fim and its subscales were excellent (α ≥ 0.97). the results for criterion validity by adjusting the v...

BACKGROUND Corus CAD is a clinically validated test based on age, sex, and expression levels of 23 genes in whole blood that provides a score (1-40 points) proportional to the likelihood of obstructive coronary disease. Clinical laboratory process variability was examined using whole blood controls across a 24 month period: Intra-batch variability was assessed using sample replicates; inter-bat...

 In this paper, we study stochastic comparisons of order statistics of independent random variables with proportional hazard rates, using the notion of variance majorization.

Dimensional variation reduction is critical to assure high product quality in discrete-part manufacturing. Recent innovations in sensor technology enable in-process implementation of laseroptical coordinate sensors and continuous monitoring of product dimensional quality. The abundance of measurement data provides an opportunity to develop next generation process control technologies that not o...
