Why should we correct reported pulsation frequencies for stellar line-of-sight Doppler velocity shifts?

open access: yes, 2014
In the age of Kepler and Corot, extended observations have provided estimates of stellar pulsation frequencies that have achieved new levels of precision, regularly exceeding fractional levels of a few parts in $10^{4}$.

Establishment of local diagnostic reference levels for CT colonography at a tertiary hospital

open access: yesSouth African Journal of Radiology
Background: Diagnostic reference levels (DRLs) are an important metric in identifying abnormally high radiation doses in diagnostic examinations. National DRLs for CT colonography do not currently exist in South Africa, but there are efforts to collect ...

Hierarchical video summarisation in reference frame subspace [PDF]

open access: yes, 2009
In this paper, a hierarchical video structure summarization approach using Laplacian Eigenmap is proposed, where a small set of reference frames is selected from the video sequence to form a reference subspace to measure the dissimilarity between two ...

Confusion in the interpretation of prolactin levels caused by inappropriately low reference intervals

open access: yesEndocrine Connections
Objective: Serum prolactin measurements are important in the differential diagnosis of pituitary masses and subfertility. We observed discrepancies in serum prolactin levels in several patients measured with different immunoassays. Despite differences in
