Enhanced Radiation Exposure of Airline Crew and Passengers During the May 2024 Geomagnetic Storm
Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Enhanced radiation at aviation altitudes is a concern for flight crew and passengers. During space weather events, solar flares and coronal mass ejection (CME) driven shocks are sources of energetic particles that can reach Earth's near‐space environment and interact with its magnetic field and atmosphere.

Characterisation of a Novel Jumbo Lytic Aeromonas dhakensis Bacteriophage P19 and Its Endolysin
Microbial Biotechnology, Volume 19, Issue 1, January 2026.A jumbo, lytic myovirus phage P19 against multidrug‐resistant (MDR) Aeromonas dhakensis was isolated from river water. P19 demonstrated robust lytic activity, high thermal and pH stability (pH 6–10, up to 60°C), and no genes associated with lysogeny, virulence or antimicrobial resistance. ORF_358 of P19 encodes for T4‐type lysozyme.

Solar Energetic Particle Events During May 2024 Geomagnetic Superstorm
Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract Three solar energetic particle (SEP) events originating from solar active region 13664 occurred on 10–16 May 2024, coinciding with a geomagnetic superstorm. Using data from the Geostationary Operational Environmental Satellites and Meteorological Operational satellite‐C, we investigate the energetic proton fluxes and east‐west flux ratios in ...

Journal of Applied Clinical Medical Physics, Volume 26, Issue 12, December 2025.Abstract Background ExacTrac Dynamic (ETD) is a novel patient positioning and motion management system for radiation therapy that combines surface guidance, thermal imaging, and stereoscopic x‐rays for image guidance. This combination of technology enables both intrafraction monitoring and surface‐based breath hold gating capabilities.

Dynamic Chiral Plasmonic Systems‐Based on Spiropyran Derivatives and Gold Nanorods
Advanced Materials Interfaces, Volume 12, Issue 23, December 8, 2025.Soft chiral plasmonic nanocomposites are prepared by embedding gold nanorods into spiropyran‐based supramolecular gels. The system self‐assembles into helical structures, enabling plasmonic circular dichroism. When illuminated with UV light spiropyran–merocyanine isomerization occurs, inducing reversible nanoscale reorganization and modulation of the ...

Polarimetric Observations of Spiral Galaxies
Publications of the Astronomical Society of the Pacific, 1967 The extragalactic systems NCC 3031, NCC 4594, NGC 5194, and NGC 5457 have been observed polarimetrically. Linear polarization between 0.1 and 1.0 percent was detected in the spiral arms of all four galaxies. The planes of vibration indicate that reflection as well as interstellar absorption of starlight by the internal dust clouds of the observed ...

Very large spiral galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1983 As a first step in the systematic study of large spirals, which may be useful in cosmological tests and studies of galaxy evolution, a catalog of the 107 largest known spiral galaxies is presented. Catalog galaxies have isophotal diameters greater than 90 kpc, assuming an H(zero) value of 50 km/sec per Mpc.
