A Chemodynamical Simulation of Halo Stars in the Milky Way

open access: yes, 2007
In this contribution, we present a new chemodynamical model for the early evolution history of the Milky Way with an improved chemical evolution description. Our new approach is based on the chemical evolution model by Tsujimoto et al. (1999).

The Mass of the Milky Way Galaxy [PDF]

open access: yes, 2023
On the Basis of tabular values of the gravitational constant. The calculated mass of the nucleus of the milky way galaxy. The numerical value of the gravitational constant is determined by the mass of the nucleus of the milky way galaxy.

Inhibition of cyclin‐dependent kinases 12/13 using CT7439 as a treatment for colorectal cancer with CDK12 upregulation

open access: yesMolecular Oncology, EarlyView.
The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and

The origin of the Milky Way globular clusters [PDF]

open access: yes, 2017
We present a cosmological zoom-in simulation of a Milky Way-like galaxy used to explore the formation and evolution of star clusters. We investigate in particular the origin of the bimodality observed in the colour and metallicity of globular clusters ...

The Age-dependent Vertical Actions of Young Stars in the Galaxy

open access: yesThe Astrophysical Journal
Stars in the Galactic disk are born on cold, nearly circular orbits with small vertical excursions. After their birth, their orbits evolve, driven by small- or large-scale perturbations in the Galactic disk’s gravitational potential.

The Chemical Evolution of the Milky Way in a cosmological context [PDF]

open access: yesEAS Publications Series, 2007
A short overview is presented of several topics concerning the evolution of the Milky Way (MW) in a cosmological context. In particular, the metallicity distribution of the MW halo is derived analytically and the halo metallicity and abundance patterns are compared to those of Local Group galaxies.

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

open access: yesMolecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Estimating the Initial Mass of the Gaia–Enceladus Dwarf Galaxy with a Chemical Evolution Model

open access: yesThe Astrophysical Journal
This work investigates the initial mass and chemical evolution history of the Gaia–Enceladus dwarf galaxy. We combine spectroscopic data from APOGEE with astrometric data from Gaia Data Release 3 to identify Gaia–Enceladus candidate stars via a machine ...
