How Metals Are Transported In And Out Of A Galactic Disk: Dependence On The Hydrodynamic Schemes In Numerical Simulations [PDF]
, 2021 Metallicity is a fundamental probe for understanding the baryon physics in a galaxy. Since metals are intricately associated with radiative cooling, star formation, and feedback, reproducing the observed metal distribution through numerical experiments will provide a prominent way to examine our understandings of galactic baryon physics. In this study,

Evaluation of the effect of metal stents on dose perturbation in the carbon beam irradiation field
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Propose Carbon ion therapy is indicated for cases in which stents have been inserted, such as bile ducts, but the effect of metal stents on carbon ion therapy is unclear. In this study, the dose perturbation of carbon ion therapy caused by metallic bile duct stents was evaluated by dosimetry. Materials and methods Five different types of metal

Metallicity gradients in local field star-forming galaxies: insights on inflows, outflows, and the coevolution of gas, stars and metals [PDF]
, 2015 We present metallicity gradients in 49 local field star-form ing galaxies. We derive gas- phase oxygen abundances using two widely adopted metallicity calibrations based on the (O III)/H , (N II)/Hand (N II)/(O II) line ratios.

CO Emission, Molecular Gas, and Metallicity in Main-sequence Star-forming Galaxies at z ∼ 2.3
The Astrophysical Journal, 2023 We present observations of CO(3−2) in 13 main-sequence z = 2.0–2.5 star-forming galaxies at $\mathrm{log}({M}_{* }/{M}_{\odot })=10.2\mbox{--}10.6$ that span a wide range in metallicity (O/H) based on rest-optical spectroscopy. We find that ${L}_{\mathrm{

Linking dust emission to fundamental properties in galaxies: the low-metallicity picture [PDF]
, 2015 Aims. In this work, we aim to provide a consistent analysis of the dust properties from metal-poor to metal-rich environments by linking them to fundamental galactic parameters. Methods.

The Regulation of Trace Metal Elements in Cancer Ferroptosis
Advanced Biology, EarlyView.The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

The Mass-Metallicity Relation at z≳2 [PDF]
, 2006 We use a sample of 87 rest-frame UV-selected star-forming galaxies with mean spectroscopic redshift ⟨z⟩ = 2.26 ± 0.17 to study the correlation between metallicity and stellar mass at high redshift.
