The log-concave maximum likelihood estimator of a density on the real line based on a sample of size n is known to attain the minimax optimal rate of convergence of O(n−4/5) with respect to, for ...

An empirical method, designated as DMR (density-magnetic resonance) porosity, combines density and nuclear magnetic resonance porosities to improve the estimate of tight gas sand porosity. The DMR ...

The inset scatter plot shows the natural log-transformed aerial density (log No./10 3 m 3) of all high-flying insects sampled over time (1926-2017). The data points are color-coded by continent, with ...
