Predictive radar tracking reveals >500 mV/m electric-field transients during the May 2024 superstorm

arXiv:2605.31046v2 Announce Type: replace Abstract: The bulk motion of E-region radar aurora provides a sparsely distributed, direct measurement of the ionospheric electric field in intermittent bursts. We present a tracking procedure for \textsc{icebear} VHF measurements of Farley-Buneman waves. Each cluster is represented as an $\alpha$-shape; frame-to-frame association is a Hungarian linear-assignment problem with a cost combining centroid distance and shape Intersection-over-Union;...

CobSeg: Coherence Boundary Modeling for Dialogue Topic Segmentation

arXiv:2605.30668v1 Announce Type: new Abstract: Dialogue topic segmentation is critical in many human-AI collaborative applications which requires identifying heterogeneous boundary cues, including lexical transitions near utterance edges and semantic discontinuities across utterances. Existing utterance models often dilute these local lexical signals. We propose CobSeg, a novel multi-branch architecture that separates coherence-level semantic continuity from lexical boundary transitions and...

MH-53E Sea Dragon: Why US navy's mine-hunting is retiring after 40 years

As tensions in the Middle East continue to focus attention on maritime security and the strategic Strait of Hormuz, one aircraft has repeatedly found itself back in the spotlight: the MH-53E Sea Dragon. For nearly four decades, the massive helicopter has served as the US Navy's primary airborne mine countermeasures platform, capable of detecting, sweeping and neutralising naval mines that threaten commercial shipping and military vessels. However, the aircraft is now approaching the end of...
