Impacts of Mid‐Latitude Ionospheric Dynamics on RF Applications During the November 2025 Superstorm Event

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract This study demonstrates the intriguing and complex interplay among auroral precipitation, enhanced TEC, density irregularities, and amplitude scintillations observed during the November 2025 superstorm. For the first time, we present observations of strong amplitude scintillation across continental United States (CONUS)—nearly from coast to ...

SynthPET: A 3D generative AI approach for FDG‐PET image synthesis from T1‐weighted MRI and ASL CBF in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 9, September 2026.
Abstract INTRODUCTION Fluorodeoxyglucose (FDG) positron emission tomography (PET) is widely used for detecting metabolic changes associated with neurodegeneration in Alzheimer's disease (AD) and other dementias but is costly and involves ionizing radiation. Here we developed SynthPET, a multimodal deep learning framework that synthesizes FDG PET images

The Impacts of Tropospheric Gravity Wave‐Generated MSTIDs on Skywaves at Mid‐latitude North American Sector Observed and Modeled Using SuperDARN HF Radars

Radio Science, Volume 61, Issue 9, September 2026.
Abstract Trans‐ionospheric high frequency (HF: 3–30 MHz) response to atmospheric gravity waves (GWs) is studied in the middle‐latitude ionosphere in relation to thunderstorm activity. SuperDARN HF radar observations are compared against the model simulations to quantify the impact of GW‐generated medium‐scale traveling ionospheric disturbances (MSTID ...

Brine Entrainment During Ice Shell Growth on Icy Worlds

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract The role of ocean composition in governing ice shell growth and ocean longevity on icy satellites remains poorly constrained. To address this, we develop a thermomechanical model of small to mid‐sized icy worlds that simulates ice shell growth from a saline ocean, explicitly quantifying brine entrainment through a parameterization of reactive ...

Inferring Io's Internal Properties by Combining Gravity Measurements and Volcanic Activity

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract With its extreme geological activity, Io represents an archetype for tidally heated exoplanets/moons and provides insight into early stages of terrestrial planet evolution. Decades of ground‐based observations and multiple space missions have refined our understanding of Io, yet it remains debated where inside Io the tidal heating takes place.

The Use of Artificial Intelligence in Enhancing Navigation Safety in Case of GNSS Signal Fading or Interference [PDF]

TransNav
Global Navigation Satellite Systems (GNSS) play a key role in modern navigation and transportation service delivery. Today it is difficult to imagine the daily operation of land, sea or air transportation without the positioning and timing provided by ...
