Correction: MN15: A Kohn-Sham global-hybrid exchange-correlation density functional with broad accuracy for multi-reference and single-reference systems and noncovalent interactions. [PDF]

open access: yesChem Sci, 2016
We report a global-hybrid approximation, MN15, to the exchange–correlation functional of Kohn–Sham theory with broadly accurate performance for both multi-reference and single-reference systems.

Emergence of Hierarchical Reference Systems in Multi-agent Communication [PDF]

open access: yesInternational Conference on Computational Linguistics, 2022
In natural language, referencing objects at different levels of specificity is a fundamental pragmatic mechanism for efficient communication in context.

Independent analysis of μδ data of ILS and INDLS catalogs to obtain the spin of the bright Gaia DR2 reference frame [PDF]

open access: yesSerbian Astronomical Journal, 2021
The Gaia DR2 reference frame should be without relative rotation to the quasars (QSOs) and consistent with the International Celestial Reference System (ICRS).

Corrections to the Hipparcos proper motions in declination for 807 stars [PDF]

open access: yesSerbian Astronomical Journal, 2008
We used the data on latitude variations obtained from observations with 10 classical photographic zenith tubes (PZT) in order to improve the Hipparcos proper motions in declinations µδ for 807 stars.

Photographic zenith tubes observations to improve HIPPARCOS proper motion in declination of some stars [PDF]

open access: yesSerbian Astronomical Journal, 2005
A procedure of calculation and results of an attempt to improve proper motions in declination for some HIPPARCOS stars are presented. A long series of optical observations of these stars observed with Photographic Zenith Tubes (PZT) are used.

Spherical trigonometry of the projected baseline angle [PDF]

open access: yesSerbian Astronomical Journal, 2008
The basic vector geometry of a stellar interferometer with two telescopes is defined by the right triangle of (i) the baseline vector between the telescopes, of (ii) the delay vector which points to the star, and of (iii) the projected baseline vector in

Earth orientation and its excitations by atmosphere, oceans, and geomagnetic jerks [PDF]

open access: yesSerbian Astronomical Journal, 2015
In addition to torques exerted by the Moon, Sun, and planets, changes of the Earth orientation parameters (EOP) are known to be caused also by excitations by the atmosphere and oceans.

Astrometric star catalogues as combination of Hipparcos/Tycho catalogues with ground-based observations [PDF]

open access: yesSerbian Astronomical Journal, 2004
The successful ESA mission Hipparcos provided very precise parallaxes positions and proper motions of many stars in optical wavelength. Therefore it is a primary representation of International Celestial Reference System in this wavelength.
