Power Leveraging: The Everyday Expansion of the Grassroots State in Urban China

Law &Policy, Volume 48, Issue 4, October 2026.
ABSTRACT China has witnessed a notable expansion of state power during and after the pandemic, particularly at the grassroots level. How has this occurred? The Shequ, a grassroots state agent, has played a central role, taking on extensive administrative responsibilities aimed at enhancing social management, often at the expense of rule‐of‐law ...

Electron Regulation of Proton Cyclotron Waves at Mars

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Proton cyclotron waves (PCWs), generated by the solar wind ionization and subsequent pickup of exospheric hydrogen, offer independent constraints on water loss from Mars. However, translating wave observations into quantitative escape rates has been hindered by an incomplete understanding of wave evolution, particularly the role of electron ...

North Sea Storm Surges Amplified by Oscillations Triggered by Preceding Storms

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Storm surges are often treated as independent extremes, yet extratropical cyclones and associated coastal water‐level extremes frequently occur in clustered sequences. Although clustering can increase flood hazard by shortening recovery time, it remains unclear whether preceding storms amplify subsequent surges.

Chorus Element Repetition: Roles of Energetic Electron Injection and Nonlinear Wave Growth

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Chorus waves are coherent whistler‐mode emissions in Earth’s magnetosphere and play a key role in the acceleration and loss of radiation belt electrons. Their spectra commonly consist of discrete and repetitive elements, yet the mechanism governing this repetition is not fully understood.

Substorm Effects on Chorus Emissions Modulated by ULF Waves

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Although cross‐scale wave‐particle interactions play a critical role in energy transfer in the magnetosphere, the influence of geomagnetic activity on the physical mechanisms involved remains unclear. In this study, we investigate this question by analyzing Van Allen Probes‐A observations of an event occurring on 25 July 2016.
