Merging Galaxies with Active Nuclei [PDF]
Symposium - International Astronomical Union, 1999 We are investigating a sample of nearby interacting and merging galaxies showing starburst properties and/or nonthermal nuclear activity (e.g. Mrk 231, Mrk 739, Mrk 1027, NGC 2992, Arp 92).

The clustering and X-ray properties of faint galaxies [PDF]
, 1994 The clustering properties of faint (23 ≤ B ≤ 27) galaxies were investigated, with the aim of obtaining information about their redshift distribution, N(z), and therefore about the processes of galaxy evolution causing the steep rise in the galaxy number ...

Interdisciplinary Medicine, EarlyView.Liquid biopsy uses non‐invasive sampling of blood or body fluids to isolate circulating analytes, including circulating tumor DNA, circulating tumor cells, extracellular vesicles, and RNA. These are analyzed using next‐generation sequencing, qPCR, and proteomics to inform cancer detection, monitoring, and characterization. Figure created with BioRender.

Star clusters in unperturbed spiral galaxies [PDF]
, 2008 Stars do not form in isolation, they form in groups known as star clusters. Star clusters are seen in a wide range of galaxies and environments. Their presence reveals the history of the host galaxy and the processes of its star formation.

AGN STORM 2. VIII. Investigating the Narrow Absorption Lines in Mrk 817 Using HST-COS Observations
The Astrophysical JournalWe observed the Seyfert 1 galaxy Mrk 817 during an intensive multiwavelength reverberation mapping campaign for 16 months. Here, we examine the behavior of narrow UV absorption lines seen in the Hubble Space Telescope/Cosmic Origins Spectrograph spectra,

JSFA reports, EarlyView.Abstract Background This study investigated the effects of crossbreeding, finishing system, and muscle type on carcass characteristics, intramuscular fat (IMF), image‐based IMF estimation, fatty acid composition, and meat quality in beef heifers. Charolais × Salers (C × S) and Angus × Salers (A × S) crossbred heifers were finished either on pasture or ...

Understanding the Concept of Self‐Performed Ultrasound: A Scoping Review
Journal of Ultrasound in Medicine, EarlyView.Self‐performed ultrasound is an emerging technology that facilitates adept self‐scans in untrained hands. Inspired by self‐performed imaging in space for more prompt diagnosis and therapy, it has the potential to accurately monitor chronic conditions remotely. However, the lack of supervision and physical restraints can hinder its usability.
