The physics of the strong interactions always has been tightly connected to the study of nucleons at shorter and shorter distances. The measurement of the anomalous magnetic moments of the proton and neutron in 1933 and 1939 made clear that nucleons are no elementary particles. During the 1950ies the Hofstadter experiments revealed the charge distributions inside nucleons at scales Q ≃ 0.5 ·M N...

t-Tests are widely used by researchers to compare the average values of a numeric outcome between two groups. If there are doubts about the suitability of the data for the requirements of a t-test, most notably the distribution being non-normal, the Wilcoxon-Mann-Whitney test may be used instead. However, although often applied, both tests may be invalid when discrete and/or extremely skew data...

Computerized dynamic posturography is commonly used to assess balance in service members, but normative values for the military population have not been established. What are Motor Control Test (MCT), Sensory Organization (SOT) and enhanced SOT (eSOT) within at which point do they differ? Cross-sectional study. 237 active duty members (78 % male) completed MCT, eSOT with sway manipulated a gain...

We present a general method for extracting the Gell Mann-Low logarithmic derivative of an e ective charge of an observable directly from data as a mean for empirically verifying the universal terms of the QCD -function. Our method avoids the biases implicit in tting to QCD-motivated forms as well as the interpolation errors introduced by constructing derivatives from discrete data. We also deri...

BACKGROUND Selenium is an essential trace element, but critically ill patients using total parenteral nutrition (PN) do not receive selenium because this mineral is not commonly offered. Threfore, the eval uation of plasma selenium levels is very important for treating or preventing this deficiency. Recent studies have shown that transthyretin may reflect the selenium intake and could be consid...
