THE DEVELOPMENT OF NAVIGATION SYSTEMS IN CIVIL AVIATION
Научный вестник МГТУ ГА, 2017 The article describes the history of navigation systems formation, such as "Cicada" system, which at that time could compete with the US "Transit", European, Chinese Beidou navigation system and the Japanese Quasi-Zenit.The detailed information about ...

Probing the Possible Causes of the Transit Timing Variation for TrES-2b in the TESS Era
The Astronomical JournalNowadays, transit timing variations (TTVs) are proving to be a very valuable tool in exoplanetary science to detect exoplanets by observing variations in transit times. To study the TTV of the hot Jupiter TrES-2b, we have combined 64 high-quality transit

Advanced Functional Materials, EarlyView.This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Which Chromium–Sulfur Compounds Exist as 2D Material?
Advanced Functional Materials, EarlyView.2D chromium sulfides synthesized using molecular beam epitaxy on graphene. Structural characterization reveals two novel 2D materials, Cr2S3‐2D, which lacks a direct bulk counterpart, and Cr223S${\rm Cr}_{2\frac{2}{3}}{\rm S}$4‐2D, a minimum thickness version of Cr5S6. However, attempts to synthesize CrS2 are unsuccessful. Both new 2D phases are stable

Sun Transit Outage Considering Solar Activity and It's Application to Koreasat [PDF]
Journal of Astronomy and Space Sciences, 1999 The purpose of this paper is to predict Sun Transit Outage phenomenon(Sunout). Sunout had been studied mainly for the case of Geostationary satellite and under the assumption of 'Quiet Sun'.

Advanced Functional Materials, EarlyView.A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

The Astronomical JournalNASA’s Transiting Exoplanet Survey Satellite (TESS) has identified over 7000 candidate exoplanets via the transit method, with gas giants among the most readily detected due to their large radii. Even so, long intervals between TESS observations for much
