Abstract In December 2019, the latest generation transportable superconducting gravimeter (SG) iGrav-043 purchased by University of Bonn was installed in Walferdange Underground Laboratory for Geodynamics (WULG) Grand Duchy Luxembourg. this paper, we estimate calibration factor iGrav-043, which is essential long-term gravity monitoring. We used simultaneously collected data from un-calibrated a...

We analyze a high-resolution, high signal-to-noise spectrum of the carbon-rich, extremely metal-poor star CS 29498–043, obtained with the Subaru Telescope High Dispersion Spectrograph. We find its iron abundance is extremely low ([Fe/H] = −3.7), placing it among the few stars known with [Fe/H] ≤ −3.5, while Mg and Si are significantly overabundant ([Mg/Fe] = +1.8, and [Si/Fe] = +1.1) compared w...

Abstract Introduction Young adults are among the populations with lowest quality diets in US, and poor sleep could be a contributing factor. Social jetlag, lack of consistent timing from weekdays to weekends, is also more common young adults. Our objective was examine associations between social jetlag diet US adults, evaluate effect modification by sex or race/ethnicity. Methods The study popu...
