Metal Preferences and Metallation [PDF]

Journal of Biological Chemistry, 2014
The metal binding preferences of most metalloproteins do not match their metal requirements. Thus, metallation of an estimated 30% of metalloenzymes is aided by metal delivery systems, with ∼ 25% acquiring preassembled metal cofactors. The remaining ∼ 70% are presumed to compete for metals from buffered metal pools.

The Effects of Doping on the Electronic Characteristics and Adsorption Behavior of Silicon Polyprismanes

Computation, 2020
Quantum–chemical calculations of the electronic characteristics of carbon and boron-doped silicon polyprismanes were carried out, and the atomic hydrogen adsorption on these structures was analyzed.

THE STUDY OF GALACTIC BEAT CEPHEIDS WITH APPLICATION OF ITS RESULTS TO THOSE IN THE MAGELLANIC CLOUDS

Odessa Astronomical Publications, 2014
A thorough study of the correlation between P1=P0 ratio, fundamental period, and chemical composition (abundances of metals that compose Z) was conducted to investigate the significance of the iron-peak elements on the ratio. The results suggested a more

A Surprising Lack of Metallicity Evolution with Redshift in the Long Gamma-Ray Burst Host Galaxy Population

The Astrophysical Journal, 2023
The number of long-duration gamma-ray burst (LGRB) host galaxies with measured metallicities and host masses has expanded sufficiently to investigate how the distributions of these properties change with redshift.

On the sizes of z>2 Damped Lyman-alpha Absorbing Galaxies [PDF]

, 2012
Recently, the number of detected galaxy counterparts of z > 2 Damped Lyman-alpha Absorbers in QSO spectra has increased substantially so that we today have a sample of 10 detections. M{\o}ller et al.

High-resolution Spectroscopic Metallicities of Milky Way Cepheid Standards and Their Impact on the Leavitt Law and the Hubble Constant

The Astrophysical Journal Letters, 2023
Milky Way Cepheid variables with accurate Hubble Space Telescope photometry have been established as standards for primary calibration of the cosmic distance ladder to achieve a percent-level determination of the Hubble constant ( H _0 ).

Properties and occurrence rates of $Kepler$ exoplanet candidates as a function of host star metallicity from the DR25 catalog [PDF]

, 2018
Correlations between the occurrence rate of exoplanets and their host star properties provide important clues about the planet formation processes. We studied the dependence of the observed properties of exoplanets (radius, mass, and orbital period) as a

Metal Metal

Artilugio, 2023
METAL METAL es una pieza electroacústica creada en 2022. El material sonoro utilizado en la composición fue grabado durante la pandemia mundial de Covid-19. Aprovechando el aislamiento obligatorio, se realizaron sesiones de improvisación rítmica, tímbrica y textural con latas de aluminio. Estas se registraron con un grabador digital Zoom H4.
