THE LOCAL DWARF GALAXIES:BUILDING BLOCKS OFMASSIVE ONES? I.THE FORNAX DWARF GALAXY
Odessa Astronomical Publications, 2008 A chemical evolution of the Local Group dwarf galaxy Fornax is considered in the framework of the merger scenario. We suppose a galactic stellar halo to be formed as separate fragments which then merge; thus, we can calculate the set of such the ...

Accuracy and interpretability of smartwatch electrocardiogram for early detection of atrial fibrillation: A systematic review and meta-analysis. [PDF]
J ArrhythmThe smartwatch ECG algorithm achieved 86% sensitivity and 94% specificity with an sAUC of 96%, while manual readings by trained personnel reached 96% sensitivity, 95% specificity, and an sAUC of 98% in a brand‐specific subgroup analysis. These findings demonstrate that the smartwatch ECG detects AFib, although 3% of results are unreadable.

Star Formation Histories with Gaia: The Galaxy and Beyond
Open Astronomy, 2003 ESA’s Gaia mission will provide accurate astrometric, photometric and spectroscopic data for millions of stars in the Galaxy and beyond. We discuss the prospects of using this vast amount of astrophysical information for understanding star formation ...

DISCRETE X-RAY SOURCES IN GALAXY CLUSTERS
Odessa Astronomical Publications, 2020 Current studies of extragalactic X-ray sources using data from orbital observatory XMM- Newton are at the front line of X-ray astronomy. Resolution capacity of the observatory instruments enable to detect separate X-ray sources in the close galaxies.

Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa
Advanced Science, EarlyView.Sesbania, a leguminous halophyte, thrives in saline soils. Comparative genomics reveals key genomic variations—particularly chromosomal inversions—are identified as contributors to population differentiation and salt resilience. These findings advance the understanding of genomic variation driving evolution and phenotypic differentiation and offer ...

Dominant galaxies in 2dF groups [PDF]
Proceedings of the International Astronomical Union, 2004 We investigate whether the spectral-type of a locally dominant (most luminous) galaxy can be used to select sets of galaxies that are physically associated (groups). We assume that passive dominants trace a group-like potential, and SF-dominants a field-like environment.
