Abstract

The physical and chemical properties of cold and dense molecular clouds are key to understanding how stars form. Using the IRAM 30 m and NRO 45 m telescopes, we carried out a Multiwavelength line-Imaging survey of the 70 $��$m dark and bright clOuds (MIAO). At a linear resolution of 0.1--0.5 pc, this work presents a detailed study of parsec-scale CO depletion and $\rm HCO^+$ deuterium (D-) fractionation toward four sources (G11.38+0.81, G15.22-0.43, G14.49-0.13, and G34.74-0.12) included in our full sample. In each source with $\rm T, accepted by ApJ

Abstract

Also part of the Lecture Notes in Artificial Intelligence book sub series (LNAI, volume 6178); International audience; The theory of ma jorisation between real vectors with equal sum of components, originated in the beginning of the XXth century, enables a partial ordering between discrete probability distributions to be defined. It corresponds to comparing, via fuzzy set inclusion, possibility distributions that are the most specific transforms of the original probability distributions. This partial ordering compares discrete probability distributions in terms of relative peakedness around their mode, and entropy is monotonic with respect to this partial ordering. In fact, all known variants of entropy share this monotonicity. In this paper, this question is studied in the case of unimodal continuous probability densities on the real line, for which a possibility transform around the mode exists. It corresponds to extracting the family of most precise prediction intervals. Comparing such prediction intervals for two densities yields a variant of relative peakedness in the sense of Birnbaum. We show that a generalized form of continuous entropy is monotonic with respect to this form of relative peakedness of densities.
