In the initial state, the nuclear environment affects the free nucleon PDFs, which are modified depending on the parton fractional momentum xB, the four-momentum transfer squared and the atomic mass number A, as it was first observed by the European Muon Collaboration [5]. At the large ...

(at least according to the widely-believed "hoop conjecture"), one corollary of Bekenstein's bound is the holographic bound: the information content of any region is at most proportional to the surface area of the region, at a rate of one bit per Planck length squared, or 1.4 × 1069 ...
The smoothing parameter of the lasso regression was optimized by finding the with lowest mean squared error in a 500-fold cross validation and picking the simplest model with misclassification error within one standard error. To estimate determinants of ERV-9/LTR12C expres- sion, we fit a ...
On the other hand, rotational autoionization processes that occur at high n have no mass dependence at all, but instead are proportional to the squared difference, (μpσ-μpπ)2, of the spatial components the molecule-fixed quantum defects [3]. The mass-dependences of vibronic interactions ...
