After an oral load of 10 g polyethylene glycol, its concentration in the urine was measured by gas chromatography. The coefficient of variation of the imprecision between run was about 11%. The urinary excretion was 25% of the administered dose with a coefficient of variation of the interindividual variation 26% and the intraindividual variation between 13% and 29%.

to perform stability analysis and study g*e interaction, eight commercial sugar beet varieties were evaluated in eight major sugar beet producing areas of karaj, mashad, miandoab, esfahan, shiraz, kermanshah, moghan and hamadan in three years using a randomized complete block design with four replications. the evaluated varieties were br1, 7233, pp.8, ic, 7233-p29, pp22, h5505 and 41rt. having ...

Some statistics in common use take a form of a ratio of two statistics such as sample correlation coefficient, Pearson’s coefficient of variation and so on. In this paper, obtaining an asymptotic representation of the ratio statistic until the third order term, we will discuss asymptotic mean squared errors of the ratio statistics. We will also discuss bias correction of the sample correlation ...

This paper illustrates the design of a nonlinear filter for edge-enhancing smoothing of multiplicative noise using a morphology-based filter structure. This filter is called the Minimum Coefficient of Variation (MCV) filter. The coefficient of variation is the ratio of the standard deviation of a random process to its mean. For an image corrupted only by stationary multiplicative noise, the coe...

PURPOSE To investigate the variation and symmetry of cone density distribution along the nasal and temporal retina of fellow eyes. METHODS An adaptive optics retinal camera (rtx1; Imagine Eyes) was used to obtain images of the parafoveal cone mosaic in 20 healthy subjects. Cone density was estimated at 250, 420, 760, and 1,300 μm eccentricity from the fovea along the nasal and temporal retina...

A b s t r a c t . We examine the effects of changing the coefficient of variation (CV) of the inter-stimulus interval on the CV of the output interspike interval (ISI), using constant magnitude, supra-threshold pointprocess stimuli of the membrane potential variable in the FitzHughNagumo model. The coefficient of variation of the input is changed within the context of a displaced exponential di...
