JWST Reveals Bulge-dominated Star-forming Galaxies at Cosmic Noon

The Astrophysical Journal Letters
Hubble Space Telescope imaging shows that most star-forming galaxies at cosmic noon—the peak of cosmic star formation history—appear disk-dominated, leaving the origin of the dense cores in their quiescent descendants unclear.

DICED (Database of Identified Cleavage Sites Endemic to Diseases States): A Searchable Web Interface for Terminomics/Degradomics

PROTEOMICS, EarlyView.
ABSTRACT Proteolysis is an irreversible posttranslational modification with immense biological impact. Owing to its high disease significance, there is growing interest in investigating proteolysis on the proteome scale, termed degradomics. We developed ‘Database of Identified Cleavage sites Endemic to Disease states’ (DICED; https://diced.lerner.ccf ...

Synergies in Self‐Assembly—From Supramolecular Polymers to Defined Hierarchical Superstructures

Journal of Polymer Science, EarlyView.
Shaping supramolecular polymers built from molecular building blocks into superstructures with defined dimensions. Synergies within supramolecular architectures such as chirality or an additional second orthogonal driving force that does not interfere with the central supramolecular motif facilitate the confinement of the growth of these ...

Anatomy of the Star Formation in a Tidally Disturbed Disk Galaxy: NGC 3718

The Astrophysical Journal
We present a UV, optical, and near-IR study of the star-forming complexes in the nearby peculiar galaxy NGC 3718, using Ultraviolet Imaging telescope, Galaxy Evolution Explorer, Spitzer, and DECam Legacy Survey imaging data.

Distribution and Kinematics of Classical Cepheids in the Galactic Outer Ring

Open Astronomy, 2015
The existence of an outer ring in the Galaxy can explain the kinematics of OB associations in the Perseus and Sagittarius stellar-gas complexes. Moreover, it can also explain the orientation of the Carina arm with respect to the major axis of the bar. We

Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten

physica status solidi (b), EarlyView.
This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...

On the Possibility of Determining the Distance to the Galactic Center from the Geometry of Spiral Arm Segments

Open Astronomy, 2015
A new approach to determining the solar galactocentric distance, R0, from the geometry of spiral-arm segments is proposed. Geometric aspects of the problem are analyzed and a simplified three-point method for estimating R0 from objects in a spiral ...

The Extremely Low Mechanical Force Generated by Nano‐Pulling Induces Global Changes in the Microtubule Network, Nuclear Morphology, and Chromatin Transcription in Neurons

Small, EarlyView.
Nano‐pulling induces stabilization, reorganization, and reorientation of the microtubule network. The nucleus of stretched cells experiences increased lateral tension, becomes more spherical, and develops surface grooves. At the level of gene expression regulation, changes in nuclear morphology induce global chromatin remodeling, leading to reduced ...
