ACTION-BASED DYNAMICAL MODELING FOR THE MILKY WAY DISK [PDF]
The Astrophysical Journal, 2016 ABSTRACT We present RoadMapping, a full-likelihood dynamical modeling machinery that aims to recover the Milky Way’s (MW) gravitational potential from large samples of stars in the Galactic disk. RoadMapping models the observed positions and velocities of stars with a parameterized, three-integral distribution function (DF) in a ...

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance
Advanced Functional Materials, EarlyView.A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Generalized Rotation Curves of the Milky Way from the GAIA DR3 Data Set: Constraints on Mass Models
The Astrophysical JournalThe circular velocity curve traced by stars provides a direct means of investigating the potential and mass distribution of the Milky Way. Recent measurements of the Galaxy’s rotation curve have revealed a significant decrease in velocity for Galactic ...

An Ultrapotent, Ultraeconomical, Antifreeze Polypeptide
Advanced Materials, EarlyView.Simple and inexpensive polypeptides composed of random copolymers of alanine and glutamic acid are effective antifreezes for applications in foods and biomedicine. The polypeptides, inspired by natural extremophile proteins, inhibit the growth of large ice crystals and prevent damage to sensitive biologics.

Cosmological pseudobulge formation
, 2012 Bulges can be classified into classical and pseudobulges; the former are considered to be end products of galactic mergers and the latter to form via secular evolution of galactic disks.

THE VERTICAL METALLICITY GRADIENT OF THE MILKY WAY DISK: TRANSITIONS IN [α/Fe] POPULATIONS [PDF]
, 2014 Using G dwarfs from the Sloan Extension for Galactic Understanding and Exploration (SEGUE) survey, we have determined the vertical metallicity gradient in the Milky Way's disk and examined how this gradient varies for different [α/Fe] subsamples.

The Space Within: How Architected Voids Promote Tissue Formation
Advanced Materials, EarlyView.This review explores the role of void spaces in tissue engineering scaffolds and examines four key methods for introducing porosity into hydrogels at different scales. It discusses sacrificial templating, microgels, phase separation, and 3D printing, highlighting principles, advantages, and limitations. It also addresses emerging strategies integrating

CHEMICAL CARTOGRAPHY WITH APOGEE: LARGE-SCALE MEAN METALLICITY MAPS OF THE MILKY WAY DISK [PDF]
, 2013 We present Galactic mean metallicity maps derived from the first year of the SDSS-III APOGEE experiment. Mean abundances in different zones of projected Galactocentric radius (0 < R < 15 kpc) at a range of heights above the plane (0 < |z| < 3 kpc), are ...
