Dynamical Models of the Milky Way in Action Space with LAMOST DR8 and Gaia EDR3

The Astrophysical Journal
This work explores dynamical models of the Milky Way (MW) by analyzing a sample of 86,109 K giant stars selected through cross-matching the LAMOST DR8 and Gaia EDR3 surveys. Our earlier torus models of Q. Wang et al.

Dynamical evidence of the age-metallicity relation in the Milky Way disk [PDF]

Astronomy & Astrophysics, 2006
We studied the relationship between the average stellar abundance of several elements and the orbital evolution of stars in the neighbourhood of the Sun, using both observational data for 325 late-type dwarfs in a volume-complete sample and simulations of the orbital diffusion.

Robust Systemic and Mucosal Immune Responses to Coxsackievirus B3 Elicited by Spider Silk Protein Based Nanovaccines via Subcutaneous Immunization

Advanced Functional Materials, EarlyView.
Spider minor ampullate silk protein (MiSp) and retinoic acid (RA) based nanovaccine are capable of eliciting both mucosal and systemic immune responses following subcutaneous administration and demonstrate significant protective effects against CVB3 infection in mice.

Orbital Torus Imaging: Acceleration, Density, and Dark Matter in the Galactic Disk Measured with Element Abundance Gradients

The Astrophysical Journal
Under the assumption of a simple and time-invariant gravitational potential, many Galactic dynamics techniques infer the milky Way’s mass and dark matter distributions from stellar kinematic observations.

Deep Potential: Recovering the Gravitational Potential from a Snapshot of Phase Space

The Astrophysical Journal, 2023
One of the major goals of the field of Milky Way dynamics is to recover the gravitational potential field. Mapping the potential would allow us to determine the spatial distribution of matter—both baryonic and dark—throughout the galaxy.

3D‐Printed and Recombinant Spider Silk Particle Reinforced Collagen Composite Scaffolds for Soft Tissue Engineering

Advanced Functional Materials, EarlyView.
The newly developed, combined 3D‐extrusion bioprinting process of a collagen ink and a recombinant spider silk precipitation bath with a subsequent potassium phosphate post‐treatment fabricates spider silk particle‐reinforced, fibrillar collagen scaffolds with promising properties for soft tissue engineering.

The Milky Way’s Rowdy Neighbors: The Effects of the Large Magellanic Cloud and Sagittarius Dwarf on the Milky Way Disk

The Astrophysical Journal
The Milky Way (MW) is a barred spiral galaxy shaped by tidal interactions with its satellites. The Large Magellanic Cloud (LMC) and the Sagittarius dwarf galaxy (Sgr) are the dominant influences at the present day. This paper presents a suite of four 10 ^

The early gaseous and stellar mass assembly of Milky Way-type galaxy halos [PDF]

, 2016
How the Milky Way has accumulated its mass over the Hubble time, whether significant amounts of gas and stars were accreted from satellite galaxies, or whether the Milky Way has experienced an initial gas assembly and then evolved more-or-less in isolation is one of the burning questions in modern astronomy, because it has consequences for our ...

The Milky Way's bright satellites as an apparent failure of LCDM

, 2012
We use the Aquarius simulations to show that the most massive subhalos in galaxy-mass dark matter halos in LCDM are grossly inconsistent with the dynamics of the brightest Milky Way dwarf spheroidal galaxies.

A Novel Protein‐Polysaccharide Oral Nanoemulsion Targeting Activated Hepatic Stellate Cells to Enhance the Therapeutic Effect of Pirfenidone on Fibrosis After Transarterial Chemoembolization for Liver Cancer

Advanced Functional Materials, EarlyView.
Transarterial Chemoembolization (TACE) may aggravate liver fibrosis. In this study, a novel oral targeting nanoemulsion is fabricated to enhance the therapeutic effect of antifibrotic drug‐pirfenidone (PFD) on fibrosis after TACE. Studies have shown that PFD nanoemulsion can enhance the oral liver targeting effect of PFD, and effectively improve the ...
