Pointing LISA-like gravitational wave detectors [PDF]
arXiv, 2013 Space-based gravitational wave detectors based on the Laser Interferometer Space Antenna (LISA) design operate by synthesizing one or more interferometers from fringe velocity measurements generated by changes in the light travel time between three spacecraft in a special set of drag-free heliocentric orbits.

Fractionated solar power satellite for regional coverage [PDF]
, 2012 This paper presents a preliminary analysis of a fractionated solar power satellite system for regional coverage. The fractionated system is composed of a cluster of satellites, in different possible configurations, that concurrently beam energy to the ...

Scaling of the electron dissipation range of solar wind turbulence
, 2013 Electron scale solar wind turbulence has attracted great interest in recent years. Clear evidences have been given from the Cluster data that turbulence is not fully dissipated near the proton scale but continues cascading down to the electron scales ...

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract Solar wind directional discontinuities can generate transient mesoscale structures such as foreshock bubbles and hot flow anomalies (HFAs) upstream of Earth's bow shock. These structures can have a global impact on near‐Earth space, so understanding their formation conditions is essential.

Field‐Aligned Proton Beams Upstream of the Martian Bow Shock: First Observations
Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.Abstract We report fast sunward‐propagating energetic proton field‐aligned beams (FABs) observed about one Mars radius upstream of the Martian bow shock, recorded by the Solar Wind Ion Analyzer instrument on the MAVEN spacecraft. The velocity distributions show that all the beams have a bulk parallel speed vB=(1.35±0.21)VS ${v}_{B}=(1.35\pm 0.21){V}_{S}

Deep Temporal Clustering : Fully Unsupervised Learning of Time-Domain Features [PDF]
arXiv, 2018 Unsupervised learning of time series data, also known as temporal clustering, is a challenging problem in machine learning. Here we propose a novel algorithm, Deep Temporal Clustering (DTC), to naturally integrate dimensionality reduction and temporal clustering into a single end-to-end learning framework, fully unsupervised.

Solar Terminator Waves Revealed as Dominant Features of Upper Thermospheric Density
Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.Abstract Observations of solar terminator waves (STWs) in thermospheric mass density (TMD) measurements above 500 km reveal STWs as dominant features of the upper thermosphere. While previous investigations have shown that STWs in the middle‐lower thermosphere have amplitudes on the order of 6%–8% of the background TMD in that region, this study shows ...
