Properties of Galaxies with Counter-rotating Stellar Disks in the MaNGA Survey
The Astrophysical JournalThe gas accretion process can fuel both star formation and black hole activity, playing a critical role in galaxy evolution. The counter-rotating structures are believed to originate from gas accretion, serving as an ideal laboratory to study its impact ...

Similar Signatures of Coplanar Gas Inflow and Disk Warps in Galactic Gas Kinematic Maps
The Astrophysical Journal, 2023 Hydrodynamic simulations suggest that galactic gas disks form when coplanar gas spirals into the inner regions of the disk. We recently presented a simple modified accretion disk model of viscous galactic disks in which star formation is fed by a radial ...

Cell Proliferation, EarlyView.Polyamine metabolism is innervation responsive and involved in denervation‐induced muscle atrophy. Inhibition of polyamine metabolism attenuates muscle atrophy by restraining proteolysis and preserving MuSCs homeostasis. Denervation‐induced activation of FAP‐derived FGF7 drives premature MuSCs activation, while DFMO suppresses this paracrine cue to ...

THE ACCRETION GEOMETRY IN RADIO-LOUD ACTIVE GALAXIES [PDF]
Modern Physics Letters A, 2007 We review the latest attempts to determine the accretion geometry in radio-loud active galactic nuclei (AGN). These objects, which comprise ~ 10–20% of the AGN population, produce powerful collimated radio jets that can extend thousands of parsecs from the center of the host galaxy. Recent multiwavelength surveys have shown that radio-loudness is more

Diverse Pathways for Supermassive Black Hole–Galaxy Coevolution
The Astrophysical JournalSupermassive black holes (SMBHs) are observed in diverse galaxy populations across cosmic time, yet a clear understanding of how they coevolve with their hosts has not been reached.

Journal of Gastroenterology and Hepatology, EarlyView.ABSTRACT Background Although Helicobacter pylori plays a central role in gastric cancer (GC), other microorganisms involved in gastric dysbiosis may also impact carcinogenesis. We aimed to characterize gastric dysbiosis and its role in the transition from non‐atrophic gastritis (NAG) to gastric premalignant lesions (GPLs) in two populations from Nariño,

The Physics of Galaxy Accretion
How do galaxies get the gas needed to fuel star formation?' remains a fundamental open question, even for the Milky-Way. I will review recent theoretical developments in galaxy accretion physics, which go beyond the classic separation between 'cold' and 'hot' accretion. I will also discuss the potential implications of different accretion modes for the

Accretion of satellite galaxies and the density of the Universe [PDF]
Monthly Notices of the Royal Astronomical Society, 1994 Recent work suggests that the disc mass of a galaxy like our own cannot have grown by more than 10 per cent through the accretion of satellites over the last 5 Gyr, greater accretion would have led to excessive thickening of the stellar disc. This limit has been interpreted as requiring a low-density universe, since current merger rates are then ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Forward genetics has been instrumental in identifying genes underlying desirable traits, yet its application to polyploid plants, many of which are key agricultural crops, remains challenging due to their genomic complexity. Therefore, we developed BenthMap, a bulk segregant analysis platform for high‐throughput trait mapping and gene ...
