Basins of Attraction and Escape in Pendulum‐Type Potentials with Quadratic Air Drag

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.
ABSTRACT Quadratic air drag is a common dissipative mechanism at moderate to high velocities, yet in nonlinear one‐degree‐of‐freedom systems, it typically blocks closed‐form solutions and energy‐based phase‐plane partitions. We study the autonomous class ẍ+α(x)|ẋ|ẋ+β(x)sgn(ẋ)+V′(x)=0,$$\begin{equation*} \ddot{x}+\alpha (x)\,|\dot{x}|\,\dot{x}+\beta

Excitation of Large Amplitude Compressional ULF Waves in the Magnetosphere by Solar Wind Pressure Spikes and IMF Southward Turning

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We present a case study of large amplitude, compressional Pc5 waves observed by GOES 13 and 15 at geosynchronous orbit near noon. These waves were excited near the arrival time of two consecutive solar wind dynamic pressure spikes at the magnetopause, the second of which was associated with a large and rapid southward turning of the ...

Thermochemical Controls on the X, 410, and 660 Discontinuities in the Central Mediterranean

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The mantle beneath the Central Mediterranean is thermally and compositionally heterogeneous, as indicated by fragmented and locally stagnant slabs in tomographic images and HIMU‐like anorogenic magmatism. Mantle discontinuities are sensitive to both temperature and composition, and thus provide a way to quantify these heterogeneities.

Spatial Variability and Drivers of Salt Marsh Cliff Erosion in the Dutch Wadden Sea: From Observation to Simulation

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Lateral erosion of salt marshes via cliff retreat is a primary cause of global marsh loss, driven by interactions between hydrodynamics, sediment, and vegetation. While previous studies show a linear relationship between wave power and cliff retreat, models based on this relationship are largely unvalidated for short‐term (sub‐yearly) and ...

Assessment of a Finite Volume Discretization of the Horizontal Pressure Gradient Force Beneath Sloping Ice Shelves

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract The accurate computation of pressure gradients in ocean models is essential for simulating ocean and climate processes. Inaccurate computation can result in spurious velocities on the order of real ocean flows, particularly in quiescent ice shelf cavities.
