Stroemgren photometry of globular clusters: M55 & M22 [PDF]
arXiv, 1999 We present Stroemgren CCD photometry for the two galactic globular clusters M55 (NGC 6809) and M22 (NGC 6656). We find average Stroemgren metallicities of -1.71 dex for M55 and -1.62 dex for M22. The determination of metal abundances in cluster giants with the Stroemgren m1 index in comparison with spectroscopic data from Briley et al.

The Metallicity Distribution Function of Red Giants in the LMC [PDF]
, 2000 We report new metallicity determinations for 39 red giants in a 220 square arcminute region, 1.8 degrees southwest of the bar of the Large Magellanic Cloud. These abundance measurements are based on spectroscopy of the Ca II infrared triplet. The metallicity distribution function (MDF) shows a strong peak at [Fe/H] = -0.57 +/- 0.04. Half the red giants

The FEBS Journal, Volume 291, Issue 12, Page 2615-2635, June 2024.The PP1:NIPP1 complex is activated by DNA damage‐induced phosphorylation of NIPP1 at Y335 by a Src kinase. This activation stems from the circularization of NIPP1, leading to de‐inhibition of associated PP1 and enhanced substrate recruitment via NIPP1.

ESO452-SC11: The lowest mass globular cluster with a potential chemical inhomogeneity [PDF]
, 2017 We present the largest spectroscopic investigation of one of the faintest and least studied stellar clusters of the Milky Way, ESO452-SC11. Using the Anglo-Australian Telescope AAOmega and Keck HIRES spectrographs we have identified 11 members of the cluster and found indications of star-to-star light element abundance variation, primarily using the ...

High-speed Laser Micromachining with Copper Bromide Laser [PDF]
arXiv, 2006 The application of the copper bromide (CuBr) laser as an attractive tool in the micro-machining of different materials has been demonstrated. High-quality drilling by trepanning and precision cutting was established on several materials with a negligible heat-affected zone (HAZ).
