Nature or Nurture: LMC-like Dust in the Solar Metallicity Galaxy M31

The Astrophysical Journal
Using the Hubble Space Telescope/Space Telescope Imaging Spectrograph, ultraviolet (UV) extinction curves have been measured in M31 along 13 new sight lines, increasing the M31 sample to 17.

THE HOT DARK MATTER MODEL: FURTHER INVESTIGATION

Odessa Astronomical Publications, 2020
e outer region with the dominant hot dark matter (the parabolic orbit of the test particle). It was assumed that the hot dark matter consists of hypothetical Planck neutrinos arising in the decay of the protons at the Planck scale.

Imagined Integration: The Logics of Japanese Immigrant Integration Policy

Policy Studies Journal, Volume 54, Issue 3, August 2026.
ABSTRACT As governments develop immigrant integration policies, they draw on and express conceptions about what successful integration looks like—what we call “imagined integration.” Yet this imagination likely displays variation that matters for implementation: integration policymaking is increasingly multilevel as it involves subnational layers of ...

Haplotype‑resolved comparison of transcription factor superfamilies between wild and cultivated autotetraploid green jujube and prioritization of candidate transcription factors via machine learning

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract A framework beyond single‐reference genomes is needed to understand transcription factor evolution. This study employed an integrated haplotype‑resolved genomes–transcriptome atlas–machine learning to characterize the transcription factors of autotetraploid green jujube (Ziziphus mauritiana).

A Comprehensive Catalog of Emission-line Nebulae, Star Clusters, and Supergiants in M31 from the LAMOST Spectroscopic Survey

The Astronomical Journal
Spectroscopic observations of various tracers in nearby galaxies, such as Andromeda (M31), play a crucial role in identifying and classifying individual stellar populations and nebular objects, thereby enhancing our understanding of galactic composition,

An Interpretable Deep Learning Model for Detecting Tropical Cyclone Genesis Through Incorporation of the Dynamic and Thermodynamic Environment

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract In recent decades, tropical cyclone (TC) track forecasting has improved significantly. However, prediction of TC genesis (TCG) remains challenging. Accurate prediction of TCG is critical for disaster prevention and mitigation. This study develops an interpretable deep learning model that integrates 3D‐residual blocks with gated recurrent units

Semiautomated classification of units in volcanic terrain based on three morphometric attributes derived from a digital elevation model (DEM)

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
The proposed method better responds to the needs of detailed cartography improving the working scale (local and regional) representation; also roughness attributes facilitate the identification of geomorphological units, and the DEM generation method enhances terrain representation.

Fifteen Years of M31* X-Ray Variability and Flares

The Astrophysical Journal
We append an additional 15 yr (2009–2024) to the Chandra X-ray light curve of M31*, the supermassive black hole (SMBH) at the center of M31, the Andromeda galaxy. Extending and expanding on the work in Z.

Lymphocyte Antigen 6G Mediates Vagotomy‐Associated Reduction in Body Weight

The FASEB Journal, Volume 40, Issue 7, 15 April 2026.
Vagotomy was associated with lower body weight and epididymal white adipose tissue (eWAT) mass, as well as increased Ly6G+ cell infiltration in eWAT. This vagotomy‐associated weight loss was significantly attenuated in neutrophil‐deficient mice, suggesting Ly6G+ cells participate in the regulation of eWAT energy homeostasis.
