Constraining spatial variations of the fine-structure constant in symmetron models
Physics Letters B, 2017 We introduce a methodology to test models with spatial variations of the fine-structure constant α, based on the calculation of the angular power spectrum of these measurements.

Toward Large Nonradiating Qubits: When Quantum Engineering Meets Photonics
Advanced Quantum Technologies, Volume 9, Issue 3, -Not available-.Nonradiating superconducting qubits suppress radiative losses through photonic‐inspired mechanisms such as anapole states and bound states in the continuum (BICs). This review surveys theoretical foundations and recent implementations of large, wavelength‐scale qubits that confine electromagnetic energy while maintaining coherence.

Accelerated Knowledge Discovery: A Vision for NASA Science
Earth and Space Science, Volume 13, Issue 3, March 2026.Abstract This paper introduces the sixth paradigm of scientific discovery: accelerated knowledge discovery (AKD). This paradigm is defined by the full integration of artificial intelligence (AI) into the research workflow as a tool augmenting cognitive capabilities of human scientists.

Model Validation of M‐I Coupling in SWMF
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract The accurate modeling of field‐aligned currents (FAC) and electron precipitation is critical for understanding magnetosphere‐ionosphere coupling and improving space weather predictions. This study evaluates the performance of the SWMF in replicating observed FAC magnitudes and distributions, as well as electron precipitation during storms and ...

Updated constraints on spatial variations of the fine-structure constant
Physics Letters B, 2016 Recent work by Webb et al. has provided indications of spatial variations of the fine-structure constant, α, at a level of a few parts per million. Using a dataset of 293 archival measurements, they further show that a dipole provides a statistically ...

Ionospheric Characterization Using VLF Whistlers
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Broadband very low frequency (VLF, 3–30 kHz) energy emitted from lightning travels long distances in subionospheric propagation modes. Some of this energy couples into the ionosphere and travels to satellite altitudes along a predominantly field‐aligned path in what is known as a “whistler” propagation mode. Along this path, these VLF signals (

ISENTROPIC "SHOCK WAVES" IN NUMERICAL ASTROPHYSICS
Odessa Astronomical Publications, 2016 Numerical simulations of the cold supersonic flows in different astrophysical problems meets with the loss of precision difficulty. For to overcome the difficulty it was suggested earlier to use conservation entropy equation instead of energy ...
