DIAGNOSTICS OF PLASMA JETS IN THE SOLAR CORONA
Solar-Terrestrial Physics, 2021 The paper discusses the diagnostics of plasma jets in the solar corona with the use of data from modern space- and ground-based telescopes observing the Sun in the extreme ultraviolet (EUV) and micro- wave bands.

MAGNETO-ACTIVE LONGITUDES IN THE SUN AND STARS
Bulletin of Taras Shevchenko National University of Kyiv. Astronomy, 2023 An overview of studies of long-term increased magnetic activity in two discrete longitudinal intervals observed on the Sun and on the surface of stars of certain types is reviewed. Active longitudes on the Sun were first discovered at the end of the 19th century.

Seismology of active regions: Current status and perspectives
Frontiers in Astronomy and Space Sciences, 2023 The goal of helioseismology is to provide accurate information about the Sun’s interior from the observations of the wave field at its surface. In the last three decades, both global and local helioseismology studies have made significant advances and ...

Detecting the Sun’s active region using image processing techniques
Physical Sciences and Technology, 2021 The term ‘space weather’ refers to adverse conditions on the Sun that could affect the structures of space or terrestrial technology and risk human health or life. Flares produce effects that span the electromagnetic spectrum.

Molecular Oncology, EarlyView.LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

The Astrophysical JournalUsing synoptic maps, we analyzed the relationship between active longitudes, the most populated longitudes of energetic flares, the distribution of magnetically complex active regions, and the preferred locations of those that produced the largest flares.

The EUV spectrum of the Sun: Quiet- and active-Sun irradiances and chemical composition [PDF]
Astronomy & Astrophysics, 2019 We benchmark new atomic data against a selection of irradiances obtained from medium-resolution quiet-Sun spectra in the extreme ultraviolet (EUV), from 60 to 1040 Å. We used as a baseline the irradiances measured during solar minimum on 2008 April 14 by the prototype (PEVE) of the Solar Dynamics Observatory Extreme ultraviolet Variability Experiment ...
