Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.Abstract This study investigates global ionospheric variability using Global Total Electron Content (GTEC), defined as the spatial average of daily averaged Global Ionospheric Maps derived from the International GNSS Service. The analysis spans from 2010 to 2024, covering Solar Cycle 24 and the rising phase of Solar Cycle 25, and incorporates ...

Prevention of venous thromboembolic complications in patients with ulcerative colitis
Терапевтический архивBackground. The incidence of venous thromboembolic complications (VTEC) in patients with inflammatory bowel diseases is approximately 3 times higher than in the general population and leads to a 2-fold increase in the risk of mortality.

The nighttime anomalies using Global IGS VTEC Maps [PDF]
, 2013 In this paper we show the VTEC variations at night, considering their geomagnetic, seasonal and solar activity dependences. The variations are analyzed in two time periods 10 p.m. (pre-midnight) and 2 a.m.

Space Weather, Volume 24, Issue 4, April 2026.Abstract The total electron content (TEC) in the ionosphere is strongly affected by solar activity and geomagnetic disturbances in mid‐ and low‐latitude regions, making it a major source of error in GNSS navigation and communication systems. To improve the prediction accuracy of ionospheric TEC, this study proposes a deep learning model—Beluga Whale ...

Space Weather, Volume 24, Issue 4, April 2026.Abstract The total solar eclipse on 8 April 2024 provided a unique opportunity to investigate the three‐dimensional (3‐D) ionospheric response under enhanced solar activity over North America. In this study, we processed high‐density GNSS observations from ∼1,700 stations to derive vertical total electron content and applied a multi‐term sinusoidal ...

New formulation for the topside ionosphere and plasmasphere based on NeQuick
Journal of Space Weather and Space ClimateThe total electron content (TEC) affecting signal propagation of Global Navigation Satellite Systems (GNSS) is strongly influenced by the topside ionosphere and plasmasphere. This study introduces a new approach to representing the two regions.
