Then, the constructed brain functional networks were filtered by three thresholding schemes: absolute threshold
, mean degree, and a novel data-driven scheme based on orthogonal minimal spanning trees (OMST), and graph theoretical measures were calculated.
The "absolute threshold
shift" method first defines the present-day threshold temperature in absolute terms ([degrees]C) and then increases it in the future.
A relative threshold defines that line based on a certain percentage of income or spending compared with everyone else; an absolute threshold
sets it at the cost to meet basic needs.
Under low light, ISO 800 is the absolute threshold
, beyond which the colours start deviating from source.
This instrument, which is no longer manufactured, was designed to measure the absolute threshold
of light perception by measuring the logarithm of light threshold against time of dark adaptation for the whole retina, or a specific location.
Hysteresis margin and absolute threshold
are determined to optimize the handover performance in .
Another common approach uses an absolute threshold
, rewarding providers if they exceed a specified level of measured quality (e.g., providers with 50 percent or more patients achieving treatment goals) (Institute of Medicine 2006; Doran et al.
. To construct a sparse representation for the boundaries, absolute threshold
discards the examples whose associated coefficients [[beta].sub.(1,2)] are close to zero.
Citing the public health implication of fall prevention, and the report by the Institute of Medicine, the authors wrote, "The absolute threshold
level of [vitamin D] needed to prevent falls in an elderly population is not known in part because of lack of true dose-ranging studies....
Thirty-seven adult dyslexic readers and 40 adult normal readers performed a battery of tests measuring auditory temporal processing (gap detection and dichotic temporal order judgment), auditory intensity processing (absolute threshold
and intensity discrimination), auditory spectral processing (spectral temporal order judgment) and working memory (backward digit span).
