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.

Scalar Material Reference Systems and Loop Quantum Gravity [PDF]

open access: yes, 2012
In the past, the possibility to employ (scalar) material reference systems in order to describe classical and quantum gravity directly in terms of gauge invariant (Dirac) observables has been emphasised frequently.

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.

Corrections of proper motions in declination by using ILS data [PDF]

open access: yesSerbian Astronomical Journal, 2006
There are nowadays numerous astrometric ground{based observations of some stars referred to Hipparcos Catalogue, made at many observatories during the last century.

The Effects of Inertial Forces on the Dynamics of Disk Galaxies

open access: yesGalaxies, 2021
When dealing with galactic dynamics, or more specifically, with galactic rotation curves, one basic assumption is always taken: the frame of reference relative to which the rotational velocities are given is assumed to be inertial.

First Principles Description of Plasma Expansion Using the Expanding Box Model

open access: yesUniverse, 2023
Multi-scale modeling of expanding plasmas is crucial for understanding the dynamics and evolution of various astrophysical plasma systems such as the solar and stellar winds. In this context, the Expanding Box Model (EBM) provides a valuable framework to
