Statistical Survey of Cosmic Noise Absorption in Conjunction With Plasma Wave Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Using a decade of observations from the Canadian Geospace Observatory Riometer Network (GO‐RIO), we selected an east‐west subset of stations near L∼7 $L\sim 7$ to classify cosmic noise absorption (CNA) (a proxy for enhanced D‐region ionization) into two morphologies, simultaneous and drifting, based on the relative timing of signals across the

Diffusion in barred-spiral galaxies

, 2010
We characterize the radial migration of stars in the disk plane by calculating the diffusion coefficient and the diffusion time-scale for a bulge-disk N-body self-consistent system with a marginally-stable Toomre-Q parameter. We find that diffusion is not constant in time, but follows the evolution of the bar, and becomes maximum near the corotation ...

Year‐round spawning increases throughput of genetic modification of common carp (Cyprinus carpio)

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract The common carp (Cyprinus carpio) is an economically and ecologically significant species. It is both one of the most highly produced fish in aquaculture globally and a persistent, widespread invasive species. Research efforts focused on understanding its biology, improving traits for aquaculture, and generating next‐generation carp control ...

Invariant manifolds in barred galaxy simulations

Astronomy & Astrophysics
Context. The origin and nature of spiral arms in barred galaxies are still under debate. Among others, the theory of invariant manifolds provides a framework capable of explaining spiral and ringed structures in these systems. Aims.

On the Role of Noncircular Motions in MaNGA Galaxies. I. Global Properties

The Astrophysical Journal
Noncircular (NC) motions represent the imprints of nonaxisymmetric structures in galaxies, providing opportunities to study the physical properties of gas departing from circular rotation.

Tracing evolutionary pathways of bar-driven quenching in local Universe disk galaxies

Astronomy & Astrophysics
Bars play an integral role in regulating star formation in spiral galaxies, from triggering central starbursts to driving quenching. The diverse star formation morphologies observed in local barred galaxies reflect different evolutionary stages of the ...

Supramolecular Aggregates of Amino Acid‐Functionalized 1,8‐Naphthalimides for Chiral Recognition

Chemistry–Methods, Volume 6, Issue 7, July 2026.
We synthesized three self‐assembling, amino acid‐functionalized 1,8‐naphthalimides. We studied their aggregation in solution and demonstrated their chiral recognition ability by fluorescence and resonance light scattering measurements. Notably, these fluorescent probes maintain their chiral recognition ability when incorporated in solid supports like ...

The TYPHOON Stellar Population Synthesis Survey. I. The Young Stellar Population of the Great Barred Spiral NGC 1365

The Astrophysical Journal, 2023
We analyze TYPHOON long-slit-absorption line spectra of the starburst barred spiral galaxy NGC 1365 obtained with the Progressive Integral Step Method covering an area of 15 kpc ^2 .
