Bootstrap technique to study correlation between neutron skin thickness and the slope of symmetry energy in atomic nuclei nucl-th We present a new statistical tool based on random sampling to assess the confidence interval of Pearson's and Spearman's correlation coefficients. These estimators are then used to qua...

Transport of internetwork magnetic flux elements in the solar photosphere astro-ph.SR The motions of small-scale magnetic flux elements in the solar photosphere can provide some measure of the Lagrangian properties of the convective flow. Measurements of these motions have been critical in estimating the turbulen...

The density of rational points near hypersurfaces math.NT math.CA We establish a sharp asymptotic formula for the number of rational points up to a given height and within a given distance from a hypersurface. Our main innovation is a bootstrap method that relies on the synthesis of Poisson summation, projective du...
