Mid-infrared Variability in Nearby Galaxies from the MaNGA Sample

The Astrophysical Journal
We use mid-infrared variability in galaxies to search for active galactic nuclei (AGN) in the local universe. We use a sample of 10,220 galaxies from the Mapping Nearby Galaxies at Apache Point Observatory survey, part of the Sloan Digital Sky Survey ...

PEARLS: Discovery of Point-source Features within Galaxies in the North Ecliptic Pole Time Domain Field

The Astrophysical Journal
The first public 0.9–4.4 μ m NIRCam images of the North Ecliptic Pole Time Domain Field uncovered galaxies displaying point-source features in their cores as seen in the longer-wavelength filters. We visually identified a sample of 66 galaxies (∼1 galaxy

X-ray Eclipses of Active Galactic Nuclei

, 2017
X-ray variation is a ubiquitous feature of active galactic nuclei (AGNs), however, its origin is not well understood. In this paper, we show that the X-ray flux variations in some AGNs, and correspondingly the power spectral densities (PSDs) of the ...

Unfolding the Network Structure of [Pyr14Cl/(BCl3)0.25]/(δ‐MgCl2)x Ionic Liquid Using the BCl4− Probe

Small Structures, EarlyView.
The network structure of ionic liquid‐based electrolytes doped with δ‐MgCl2 is unveiled using the BCl4− molecular probe. A comprehensive approach, including DFT, Fourier transform infrared, broadband electrical spectroscopy, and nuclear magnetic resonance studies, reveals the interplay between anionic and cationic domains, demonstrating enhanced ...

A Catalog of Broad Hα and Hβ Active Galactic Nuclei in MaNGA

The Astrophysical Journal
Broad H α and H β emission lines (FWHM > 1000 km s ^−1 ) are incredibly efficient tracers of the high-velocity clouds encircling active galactic nuclei (AGNs).

A patient‐derived orthotopic xenograft model unveils metastatic dynamics in head and neck squamous cell carcinoma

The FEBS Journal, EarlyView.
Metastasis in head and neck squamous cell carcinoma (HNSC) poses significant clinical challenges. This proof‐of‐concept study establishes patient‐derived orthotopic xenografts (PDOXs) as advanced models that closely replicate primary HNSC tumours, including local lymph node metastasis and the intricate cancer–stroma interaction.

From cells to pixels: A decision tree for designing bioimage analysis pipelines

Journal of Microscopy, EarlyView.
Abstract Bioimaging has transformed our understanding of biological processes, yet extracting meaningful information from complex datasets remains a challenge, particularly for biologists without computational expertise. This paper proposes a simple general approach, to help identify which image analysis methods could be relevant for a given image ...

Identifying the Secondary Jet in the RadioAstron Image of OJ 287

The Astrophysical Journal
The 136 yr long optical light curve of OJ 287 is explained by a binary black hole model where the secondary is in a 12 yr orbit around the primary. Impacts of the secondary on the accretion disk of the primary generate a series of optical flares that ...

Technical considerations and review of urinary microRNAs as biomarkers for chronic kidney disease in dogs and cats

Veterinary Clinical Pathology, EarlyView.
Abstract MicroRNAs (miRNAs or miRs) are small, non‐coding RNAs that play a crucial role in gene regulation, making them potential biomarkers for various diseases. In the field of veterinary medicine, there is a growing interest in exploring the diagnostic and therapeutic potential of miRNAs in kidney diseases affecting dogs and cats.
