Why Do Sudden Commencements Sometimes Generate Disproportionate Geomagnetically Induced Currents?

Space Weather, Volume 23, Issue 10, October 2025.
Abstract Geomagnetically Induced Currents (GICs) in grounded, conducting infrastructure (e.g., power networks) represent an important space weather hazard. GICs are driven by the changing magnetic field at the Earth's surface. Due to a sparsity of GIC measurements, the rate of change of the horizontal geomagnetic field H′ $\left({H}^{\prime }\right ...

Detection of Negative Carbon and Oxygen Pickup Ions From Dust Orbiting Jupiter

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract We report on observations of negative carbon and oxygen pickup ions (PUIs) originating from dust orbiting Jupiter. The PUIs are observed at altitudes of a few thousand kilometers (∼4,800–10,200 km) above the 1‐bar level of Jupiter's atmosphere and up to ∼11,000–15,000 km from the equatorial plane, thus providing constraints on the location of ...

Annotation‐Guided AoS‐to‐SoA Conversions and GPU Offloading With Data Views in C++

Concurrency and Computation: Practice and Experience, Volume 37, Issue 21-22, 25 September 2025.
ABSTRACT The C++ programming language provides classes and structs as fundamental modeling entities. Consequently, C++ code tends to favor array‐of‐structs (AoS) for encoding data sequences, even though structure‐of‐arrays (SoA) yields better performance for some calculations.
