THE EVOLUTION OF OXYGEN AND MAGNESIUM IN THE BULGE AND DISK OF THE MILKY WAY [PDF]
The Astronomical Journal, 2008 We show that the Galactic bulge and disk share a similar, strong, decline in [O/Mg] ratio with [Mg/H]. The similarity of the [O/Mg] trend in these two, markedly different, populations suggests a metallicity-dependent modulation of the stellar yields from massive stars, by mass loss from winds, and related to the Wolf-Rayet phenomenon, as proposed by ...

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.

The Astrophysical JournalWe present a novel, deep-learning-based method—dubbed Galactic-Seismology Substructures and Streams Hunter, or GS ^3 Hunter for short—to search for substructures and streams in stellar kinematics data.

Are Disks of Satellites Comprised of Tidal Dwarf Galaxies?
Galaxies, 2021 It was found that satellites of nearby galaxies can form flattened co-rotating structures called disks of satellites or planes of satellites. Their existence is not expected by the current galaxy formation simulations in the standard dark matter-based ...

A NEW STELLAR CHEMO–KINEMATIC RELATION REVEALS THE MERGER HISTORY OF THE MILKY WAY DISK [PDF]
, 2013 The velocity dispersions of stars near the Sun are known to increase with stellar age, but age can be difficult to determine, so a proxy like the abundance of α elements (e.g., Mg) with respect to iron, [α/Fe], is used.

An Injection‐Molded Modified Silicone Rubber for Cancer‐on‐Chip Applications
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.This study describes the characterization and application of an injection‐molded functionalized PDMS fluidic insert for the commercially available Micronit system. Modified PDMS can accommodate cell culture and is able to covalently bind proteins for long‐lasting coatings under flow‐conditions.

Rotation of galaxies and dark matter
Results in Physics, 2023 In a previous paper by the author was proposed a new metric for the gravitational field of a thin rotating disk physically different from the Kerr metric. The metric is admissible for any angular momentum of the disk. As demonstrated in the present paper

THE GAIA INERTIAL REFERENCE FRAME AND THE TILTING OF THE MILKY WAY DISK [PDF]
, 2014 While the precise relationship between the Milky Way disk and the symmetry planes of the dark matter halo remains somewhat uncertain, a time-varying disk orientation with respect to an inertial reference frame seems probable.
