TL;DR: In this article, the authors examined three samples with different constraints on parallax uncertainty and distance errors and stellar spectral types: (1) all OB stars with less than 10.5 kpc, (2) only O-type stars with 0.1 mas errors imposed and with distance errors of less than 0.2 kpc; and (3) only OD stars with

TL;DR: In this paper, the authors presented accurate absolute astrometry of 6.7 GHz methanol masers detected in the Arecibo Methanol Maser Galactic Plane Survey using MERLIN and the Expanded Very Large Array (EVLA).

TL;DR: A comprehensive set of density functional theory simulations combined with thermodynamic modeling that allow us to map out the T-p(O)2 phase diagrams and predict the oxygen affinity of Pt(x)O(y) clusters and find that the Pt clusters have a much stronger tendency to form oxides than does the bulk metal.

TL;DR: In this paper, the results of a survey of radio continuum sources near the Galactic plane using the Very Long Baseline Array (VLBA) were presented, which can be used for parallax measurements in the Bar and Spiral Structure Legacy Survey.

TL;DR: In this article, a two-step catalytic process for the conversion of organic waste-derived butyric acid to butanol was presented, where the first reaction, esterification of butyl acid, was optimized using carbon-based catalysts and the second reaction, hydrogenolysis of this methyl butyrate to butyl alcohol, was investigated using bimetallic Pt-Co catalysts.
