Genome evolution of Mediterranean olives following DNA repeats diversification

open access: yesThe Plant Genome, Volume 19, Issue 4, December 2026.
Abstract The olive tree (Olea europaea L. subsp. europaea) is one of the most representative perennial crops of the Mediterranean Basin, yet the genomic processes underlying its domestication and diversification remain poorly understood. Here, we investigated repeatome variation across 20 accessions, including 11 wild oleasters and nine cultivated ...

Modeling the Spectral Energy Distribution of Active Galactic Nuclei: Implications for Cosmological Simulations of Galaxy Formation

open access: yesThe Astrophysical Journal
Modeling the spectral energy distributions (SEDs) of active galactic nuclei (AGNs) plays a very important role in constraining modern cosmological simulations of galaxy formation.

Exploring the Potential of Unmanned Aerial System‐Based Topographic Indices Maps to Evaluate Storm Drain Positioning

open access: yesJournal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT Urbanisation, climate uncertainty, and limited city budgets have heightened the need for efficient urban drainage management. While advanced hydrodynamic models assess the performance of drainage networks, they are computationally intensive, time‐consuming, and expensive.

The impact of angular momentum on black hole accretion rates in simulations of galaxy formation [PDF]

open access: yes, 2015
: Feedback from energy liberated by gas accretion on to black holes (BHs) is an attractive mechanism to explain the exponential cut-off at the massive end of the galaxy stellar mass function.

Liquid Biopsy: Past, Present, and Future

open access: yesMedComm, Volume 7, Issue 11, November 2026.
Liquid biopsy has expanded from cancer genotyping to a broader strategy for probing both oncologic and nononcologic conditions through circulating analytes and multilayer molecular readouts. This review traces the field's past, present, and future—summarizing where liquid biopsy is most actionable today, why performance varies across contexts, and ...

Ongoing Morphological Transformation from Elliptical to Spiral Galaxies Induced by Gas Accretion from Neighboring Galaxies

open access: yesThe Astrophysical Journal
We present results from spectroscopic observations of three interacting galaxy systems, each associated with a primary galaxy—VCC 1748, SDSS J1106, and 2MASX J0834—which have been proposed as potential examples of reverse morphological transformation ...

Cosmogenic 10Be as a Tracer for Recent Heliospheric Encounters With Interstellar Cold Clouds and Nearby Supernovae

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin.

Different Influence of Gas Accretion on the Evolution of Star-forming and Non-star-forming Galaxies

open access: yesThe Astrophysical Journal
Using integral field spectroscopic data from the Mapping Nearby Galaxies at Apache Point Observatory survey, we investigate the spatially resolved properties and empirical relations of a star-forming galaxy and a non-star-forming galaxy hosting ...

Gas accretion in disk galaxies

open access: yes, 2013
Gas accretion is necessary to maintain star formation, spiral and bar structure, and secular evolution in galaxies. This can occur through tidal interaction, or mass accretion from cosmic filaments. Different processes will be reviewed to drive gas towards galaxy centers and trigger starbursts and AGN. The efficiency of these dynamical processes can be

Active Dwarf Galaxy Database. II. Connections between Host Galaxy Properties and Black Hole Accretion Signatures

open access: yesThe Astrophysical Journal
We investigate the connection between accretion signatures and host galaxy properties in the context of how active dwarf galaxies are identified. We use the database constructed in E. J. Wasleske & V. F.
