Removing the Effect of Source Structure From Correlated VLBI Data
Radio Science, Volume 61, Issue 10, October 2026.Abstract Recent studies suggest that in geodetic very long baseline interferometry (VLBI) the assumption of sources being point‐like results in a significant residual error introduced by the effect of source structure. Our aim is to remove the impact of source structure from geodetic VLBI data right after the correlation step. For this purpose, we have

Kinematics of Nuclei of Sc Galaxies [PDF]
Highlights of Astronomy, 1980 For a sample of 21 Sc galaxies with a wide range of luminosities, of radii, and of masses, W. K. Ford and I have obtained spectra and determined rotation curves. By their kinematical behavior in their central regions, the Sc’s can be separated into two groups. Some galaxies, generally small and of low luminosity, have shallow central velocity gradients,

Features of Ground Level Enhancement (GLE #74) Event on 11 May 2024
Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract Ground Level Enhancement (GLE #74) occurred on 11 May 2024 following an X5.8 solar flare from active region AR 13668 and the associated halo coronal mass ejection. The event was observed by both ground‐based neutron monitors (NMs) and space‐borne instruments and occurred during a deep Forbush decrease and one of the strongest geomagnetic ...

Space Weather, Volume 24, Issue 10, October 2026.Abstract As crewed space missions set course for the Moon and beyond, astronauts will experience prolonged exposure to Galactic Cosmic Rays (GCR) and potentially intense Solar Proton Events (SPEs), both of which pose significant short‐ and long‐term health risks.

A Study of the Continua of the Nuclei of Galaxies [PDF]
Symposium - International Astronomical Union, 1972 Many people have attacked the problem of synthesizing the stellar population of the galaxies. We have performed such a synthesis, by using only the intensities of absorption lines in the nuclei of galaxies. It is then possible to obtain a synthesized continuous spectrum even if there are several possible solutions for the stellar composition, and the ...

Journal of Applied Crystallography, Volume 59, Issue 5, Page 1693-1706, October 2026.A low‐cost, portable, medium‐resolution polarizing digital light microscope device for monitoring crystal growth and for crystal harvesting is described. The device can be used with a cell phone or a personal computer for real‐time imaging by professional and amateur scientists alike.Motivated by the need for a convenient way to demonstrate the growth ...

Cell Proliferation, Volume 59, Issue 10, October 2026.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 ...

Modular training resources for bioimage analysis
Journal of Microscopy, Volume 304, Issue 1, Page 3-14, October 2026.Abstract Modern microscopy enables us to measure structural and dynamical properties of many biological processes and is therefore an indispensable research tool. However, the amount and complexity of the produced imaging data is steadily increasing.

Genomic Signatures of Endemic Pathogen Exposure in a Declining Amphibian
Molecular Ecology, Volume 35, Issue 20, October 2026.ABSTRACT Endemic wildlife diseases can impose strong selection on threatened populations, yet whether persistence is associated with adaptive genomic responses remains poorly understood. We tested whether long‐term exposure to Batrachochytrium dendrobatidis (Bd) following population declines has left detectable selection signatures in the genome of the

Genome architecture modulates 35S and 5S rDNA homogenization in Asteraceae
The Plant Journal, Volume 128, Issue 2, October 2026.SUMMARY Concerted evolution is the model by which multicopy gene families are homogenized across genomes, with ribosomal DNA (rDNA) as its textbook example. However, the extent and efficiency of this process may vary depending on genomic factors. The plant family Asteraceae provides a natural comparative system to address the evolutionary dynamics of ...
