Detection of Contact Binary Candidates Observed By TESS Using the Autoencoder Neural Network
The Astronomical JournalA contact binary may be the progenitor of a red nova that eventually produces a merger event and have a cut-off period of around 0.2 days. Therefore, a large number of contact binaries is needed to search for the progenitor of red novae and to study the ...

Cytoskeleton, EarlyView.ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Turbulence in the Atmospheres of Eclipsing Binary Stars [PDF]
International Astronomical Union Colloquium, 1980 Abstract:A review of the orbits and dimensions of the ζ Aurigae systems is given, based on photometric and spectrographic observations. The Ca II K-line has been studied intensively to determine the extent and uneven structure of the chromospheres of these stars; the multiple structure of this line observed at several eclipses confirms the presence of ...

β Cephei Pulsators in Eclipsing Binaries Observed with TESS
The Astrophysical Journal Supplement SeriesThe combined strength of asteroseismology and empirical stellar basic parameter determinations for in-depth asteroseismic analysis of massive pulsators in eclipsing binaries shows great potential for treating the challenging and mysterious discrepancies ...

A New Binary Star System of EW Type in Draco: GSC 03905-01870
, 2018 Discovery of a new binary star system (GSC 03905-01870 = USNO-B1.0 1431-0327922 = UCAC4 716-059522) in the Draco constellation is presented. It was discovered during a search for previously unreported eclipsing binary stars through the ASAS-SN database ...

ChemMedChem, EarlyView.This study uses six small‐molecule inhibitors to evaluate optimal cellular accumulation assay conditions in a 96‐well format with high performance liquid chromatography with tandem mass spectrometry detection. The obtained medium to high‐throughput workflow is suitable for reliably identifying cellular accumulation, valuable for preclinical selection ...

KM UMa: An Active Short-period Detached Eclipsing Binary in a Hierarchical Quadruple System
The Astrophysical JournalThe first detailed photometric and spectroscopic analysis of the G-type eclipsing binary KM UMa is presented, which indicates that the system is a short-period detached eclipsing binary.

Food Safety and Health, EarlyView.This study shows the protective effects of potential probiotic strain of Pediococci strains against diarrheal Escherichia coli strains in Caenorhabditis elegans model system. The E. coli strains resulted in severe morphological and physiological damage to the worm whereas the probiotic interventions were able to reduce these damages.

Short-period Heartbeat Binaries from TESS Full-frame Images
The Astrophysical Journal Supplement SeriesWe identify 240 short-period ( P ≲ 10 days) binary systems in Transiting Exoplanet Survey Satellite data, 180 of which are heartbeat binaries. The sample is mostly a mix of A- and B-type stars and primarily includes eclipsing systems, where over 30% of ...
