Magnetic Resonance Neurography of the Brachial Plexus at 1.5 T: Diagnostic Reliability and Time Efficiency of Bilateral Ultra‐Fast 3D STIR vs. Unilateral 2D Dixon

International Journal of Imaging Systems and Technology, Volume 36, Issue 1, January 2026.
ABSTRACT Recent technological advancements may now allow shorter reliable magnetic resonance neurography (MRN) scans of the brachial plexus (BP) even at 1.5 T. The objective of this study was to compare ultra‐fast bilateral coronal 3D T2w TSE STIR (3D‐IR) with unilateral sagittal 2D T2w TSE Dixon (2D‐DX) in terms of image quality, diagnostic ...

A Cross‐Correlation Method to Evaluate Wind Retrieval Accuracy on Mars Using Simulated Microwave Limb Sounder Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract While aspects such as the temperature and composition of the Martian atmosphere are relatively well known thanks to observations from numerous space missions, Martian atmospheric dynamics remain poorly constrained due to the scarcity of direct wind measurements. The use of microwave limb sounders to retrieve winds has been proposed in the past,

exoALMA XXII: A Two-dimensional Atlas of Deviations from Keplerian Disks

The Astrophysical Journal Letters
Protoplanetary disks are the birthplaces of planetary systems, and deviations from Keplerian rotation imprinted in disk gas kinematics serve as key tracers of physical processes and the presence of protoplanets within disks.

Payload Selection Scheme for a Fast‐Response Planetary Defense Scouting Mission: The Satis CubeSat Study

Advances in Astronomy, Volume 2026, Issue 1, 2026.
The continued detection of near‐Earth asteroids with postulated close encounters with Earth is a clear motivation for planetary defense–driven mission designs. Fast reconnaissance in an imminent threat scenario (i.e., less than a few years upon impact) is crucial to gain information about an asteroid potentially impacting the Earth in the near future ...

Constraints on the Physical Origin of Large Cavities in Transition Disks from Multiwavelength Dust Continuum Emission

The Astrophysical Journal
The physical origin of the large cavities observed in transition disks is to date still unclear. Different physical mechanisms (e.g., a companion, dead zones, enhanced grain growth) produce disk cavities of different depth, and the expected spatial ...
