Until now use of the PABA test together with ["C] PABA to calculate the PABA excretion index has probably been the best adaptation suggested to enhance the specificity of this non-invasive pancreatic function test. Drawbacks of the method are the application of radioactivity, the fact that children, pregnant women, and patients with renal insufficiency have to be excluded from the test, and the...

This paper presents some testing approaches based on model checking and using different testing criteria. First, test sets are built from different Kripke structure representations. Second, various rule coverage criteria for transitional, non-deterministic, cell-like P systems, are considered in order to generate adequate test sets. Rule based coverage criteria (simple rule coverage, context de...

In this paper, we propose a method to distinguish between mechanisms leading to single molecule subdiffusion in confinement. We show that the method of p-variation, introduced in the recent paper [M. Magdziarz, Phys. Rev. Lett. 103, 180602 (2009)], can be successfully applied also for confined systems. We propose a test which allows distinguishing between heavy-tailed continuous-time random wal...

A customer is presumed to gravitate to a facility by the distance to it and the attractiveness of it. However regarding the location of the facility, the presumption is that the customer opts for the shortest route to the nearest facility. This paradox was recently solved by the introduction of the gravity p-median model. The model is yet to be implemented and tested empirically. We implemented...

m. To establish a quick and easy test to examine flicker functions of the blue-sensitive pathway in a clinica: setting. Method. A strong steady orange adaptation light was used to suppress the red and green cones. Adaptation and stimulation lights were superimposed evenly in a ping-pang ball cut in half and placed close to the eye. This provided a large stimulus field (90 ") making fixation not...

BACKGROUND Given an observed test statistic and its degrees of freedom, one may compute the observed P value with most statistical packages. It is unknown to what extent test statistics and P values are congruent in published medical papers. METHODS We checked the congruence of statistical results reported in all the papers of volumes 409-412 of Nature (2001) and a random sample of 63 results...

An unconditional exact test is a classic method to the significant difference between two independent binomial proportions or multinomial distributions. The p-value based on computed by maximizing probability of tail region. grid search and polynomial are able find maximum with sophisticated enough partition parameter space, while they require rather long time compute those methods computationa...
