MAGICS. III. Seeds Sink Swiftly: Nuclear Star Clusters Dramatically Accelerate Seed Black Hole Mergers

open access: yesThe Astrophysical Journal
Merger rate predictions of massive black hole (MBH) seeds from large-scale cosmological simulations differ widely, with recent studies highlighting the challenge of low-mass MBH seeds failing to reach the galactic center, a phenomenon known as the seed ...

Jet Interaction with Galaxy Cluster Mergers

open access: yesThe Astrophysical Journal
Abstract Active galactic nucleus (AGN) bubbles in cool-core galaxy clusters are believed to facilitate the transport of cosmic-ray electrons (CRe) throughout the cluster. Recent radio observations reveal the complex morphologies of cluster diffuse emission, potentially linked to interactions between AGN bursts and the cluster environment.

Epithelial Memory After Respiratory Viral Infection in Mice Results in Prolonged Enhancement of Antigen Presentation

open access: yesAllergy, EarlyView.
RSV infection induces lasting epigenetic and transcriptional changes in LECs, upregulating MHC‐I and MHC‐II, further amplified by LPS exposure. This is accompanied by increased antigen uptake, processing, and presentation. These persistent alterations may influence immune responses, potentially impacting both immunity to infection and respiratory ...

CO Observations of Early-mid Stage Major Mergers in the MaNGA Survey

open access: yesThe Astrophysical Journal Supplement Series
We present a study of the molecular gas in early-mid stage major mergers, with a sample of 43 major-merger galaxy pairs selected from the Mapping Nearby Galaxies at Apache Point Observatory survey and a control sample of 195 isolated galaxies selected ...

CTCF Is Essential for the Development and Maintenance of CALM‐AF10‐Induced Leukemia

open access: yesCancer Science, EarlyView.
CTCF regulates TGM2 gene expression by modulating key histone modifications, including increased acetylation of H3K27 (H3K27ac) and trimethylation of H3K4 (H3K4me3), along with decreased trimethylation of H3K27 (H3K27me3). These epigenetic changes are critical for maintaining the stem‐like properties of CALM‐AF10‐induced AML. Pharmacological inhibition

Galaxy evolution in the post-merger regime. III -- The triggering of active galactic nuclei peaks immediately after coalescence

open access: yesThe Open Journal of Astrophysics
Galaxy mergers have been shown to trigger AGN in the nearby universe, but the timescale over which this process happens remains unconstrained. The Multi-Model Merger Identifier (MUMMI) machine vision pipeline has been demonstrated to provide reliable ...

Deep Learning for Detecting Dental Plaque and Gingivitis From Oral Photographs: A Systematic Review

open access: yesCommunity Dentistry and Oral Epidemiology, EarlyView.
ABSTRACT Objectives This systematic review aimed to evaluate the performance of deep learning (DL) models in detecting dental plaque and gingivitis from red, green, and blue (RGB) intraoral photographs. Methods A comprehensive literature search was conducted across Medline, Scopus, Embase, and Web of Science databases up to January 31, 2025.
