A Comparison of Star Formation Rates by Different Tracers in Nearby Galaxies
The Astrophysical Journal Supplement SeriesWe utilize a large sample of ∼113,000 galaxies ( z < 0.3) from the Sloan Digital Sky Survey with high-quality data to compare star formation rates (SFRs) across multiple diagnostic methods and examine their connection to the strength of active galactic ...

GENERAL CATALOGUE OF VARIABLE STARS: CURRENT STATUS AND NEW NAME-LISTS
Odessa Astronomical Publications, 2010 A short history of variable-star catalogs is presented. After the second World War, the International Astronomical Union asked astronomers of the Soviet Union to become responsible for variable-star catalogs. Currently, the catalog is kept electronically

An Investigation of the Ancient Star Catalog [PDF]
Publications of the Astronomical Society of the Pacific, 1982 Various tests are applied to Claudius Ptolemy's long-suspect claim that he himself observed the more than 1000 objects in the Ancient Star Catalog. An obvious consequence of observing under the influence of Ptolemy's large equinox-position error is found not to exist in the Catalog.

Search for Wide Double Stars in the Guide Star Catalog I. All Sky Properties of the Catalog [PDF]
International Astronomical Union Colloquium, 1992 AbstractThe immediate object of this effort is the first systematic investigation of the guide star catalog as a new source list for the discovery of possible new visual binary stars. In this first paper of the series we detail on the way used to establish the properties of the catalog, i.e.

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells
FEBS Open Bio, EarlyView.To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

FEBS Open Bio, EarlyView.The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

THE CHANDRA VARIABLE GUIDE STAR CATALOG [PDF]
The Astrophysical Journal Supplement Series, 2010 Variable stars have been identified among the optical-wavelength light curves of guide stars used for pointing control of the Chandra X-ray Observatory. We present a catalog of these variable stars along with their light curves and ancillary data.
