Comparison of Interannual Oscillations in the F, E, and D‐Region Ionosphere Using Longterm Ground‐Based Measurements

Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract This comprehensive study focuses on interannual oscillations from 1 to 25 years in the F, E, and D region ionosphere. By leveraging longterm (1960–2018) continuous ground‐based ionosonde and phase height measurements in northern Germany, we have identified the peak periods and temporal variations of these oscillations using advanced analysis ...

Geomorphological Evidence of Near‐Surface Ice at Candidate Landing Sites in Northern Amazonis Planitia, Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract This work presents geomorphological analyses of an area at the boundary between Arcadia Planitia and northern Amazonis Planitia, situated in the northern mid‐latitudes of Mars. Recent studies have indicated the presence of substantial volumes of near‐surface excess ice in Arcadia Planitia, making this region a promising candidate for future ...

Electron Acceleration and Zebra Stripe Formation in Saturn's Radiation Belts

Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract This study uses the Versatile Electron Radiation Belt code to model Saturn's radiation belt environment, investigating electron acceleration, loss, and transport mechanisms. The simulations consider various physical processes, including convection particularly driven by a Volland‐Stern (VS) electric field, radial diffusion, collisional energy ...

Obras politics

American Ethnologist, Volume 52, Issue 2, Page 183-194, May 2025.
Abstract Materiality tends to play only a marginal role in mainstream theorizations of populism. In Ecuador, however, where populism has been described as the norm rather than the exception, obras (public works) are a crucial element of politics. They are framed as the gifts of leaders to the people, shaping people's lifeworlds and embedding leaders in
