Effects of the radial flows on the chemical evolution of the Milky Way disk [PDF]
, 2011 Context. The majority of chemical evolution models assume that the Galactic disk forms by means of infall of gas and divide the disk into several independent rings without exchange of matter between them.

Disk origin of the Milky Way bulge: the necessity of the thick disk [PDF]
Astronomy & Astrophysics, 2019 In the Milky Way bulge, metal-rich stars form a strong bar and are more peanut-shaped than metal-poor stars. It has recently been claimed that this behavior is driven by the initial (i.e., before bar formation) in-plane radial velocity dispersion of these populations, rather than by their initial vertical random motions.

Tracing and Capturing the Epiblast Pluripotency of Sheep Preimplantation Embryos
Advanced Science, EarlyView.This study performs a comprehensive single‐cell transcriptome analysis of sheep embryos from embryonic (E) day 1 to E14 to elucidate the mechanism of early lineage specification and the pluripotency changes (naïve, formative, and primed) of epiblast.

The Emergence of the Thick Disk in a CDM Universe II: Colors and Abundance Patterns
, 2005 The recently emerging conviction that thick disks are prevalent in disk galaxies, and their seemingly ubiquitous old ages, means that the formation of the thick disk, perhaps more than any other component, holds the key to unravelling the evolution of ...

Candidate Members of the VMP/EMP Disk System of the Galaxy from the SkyMapper and SAGES Surveys
The Astrophysical Journal Supplement SeriesPhotometric stellar surveys now cover a large fraction of the sky, probe to fainter magnitudes than large-scale spectroscopic surveys, and are relatively free from the target selection biases often associated with such studies.

ORIGIN AND EVOLUTION OF THE ABUNDANCE GRADIENT ALONG THE MILKY WAY DISK [PDF]
, 2009 Based on a simple model of the chemical evolution of the Milky Way disk, we investigate the disk oxygen abundance gradient and its time evolution. Two star formation rates (SFRs) are considered, one is the classical Kennicutt–Schmidt law (Ψ = 0.25Σ1.4gas,

Myonuclear alterations associated with exercise are independent of age in humans
The Journal of Physiology, EarlyView., 2023 Abstract figure legend Structural and mechanical properties of myonuclei in trained young and aged individuals. In skeletal muscle fibres from trained individuals, myonuclei are more spherical, have greater lamin A and are stiffer compared to untrained counterparts.
