Multi‐Wavelength Transformer‐Based 24‐Hour Solar Flare Forecasting at the Active‐Region Level
Space Weather, Volume 24, Issue 6, June 2026.Abstract Solar flare forecasting remains challenging due to the complex spatiotemporal evolution of solar active regions (ARs) and the severe class imbalance associated with high‐impact events. In this work, we investigate a transformer‐based framework for active‐region–level solar flare forecasting using short sequences of multi‐wavelength ...

Sense of Belonging in Science: A Focus on the Construct
Journal of Educational Measurement, Volume 63, Issue 2, Summer 2026.Abstract The importance of the construct to the fields of measurement and cognitive science cannot be overstated. Without an understanding of the construct, including clarity and scope of the substantive and structural aspects, one cannot ensure valid use and interpretation of a constructed measure.

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract We present a method to infer ocean diapycnal diffusivity based on high‐resolution ocean model predictions of the depth‐dependent viscous dissipation associated with internal wave shear. This method relies on recent advances in modeling and the parameterization of stratified turbulent mixing processes.

X-ray and gamma ray astronomy detectors
, 1994 X-ray and gamma ray astronomy was made possible by the advent of space flight. Discovery and early observations of celestial x-rays and gamma rays, dating back almost 40 years, were first done with high altitude rockets, followed by Earth-orbiting ...

The Astrophysical JournalThe blazars are one of the leading candidate sources of high-energy neutrinos. Recently, two blazars have been found to be temporally and spatially correlated with some IceCube high-energy neutrino events. The two blazars, GB6 J2113+1121 and NVSS J171822+

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.Abstract We report the observation of a downward terrestrial gamma‐ray flash (TGF) during the dart‐leader stage in a negative cloud‐to‐ground lightning flash. The observation was recorded by the Telescope Array Surface Detector, in conjunction with a Lightning Mapping Array, an interferometer (INTF), a fast antenna, and a high‐speed camera.
