Abstract: In this paper we consider the imaging of small electromagnetic inhomogeneities from measured limited-view near-field data. We propose a multi-frequency imaging algorithm for this purpose.

Abstract: Direction-of-arrival (DOA) estimation via noisy and one-bit quantized data has attracted considerable research interest in array signal processing. In practical scenarios, amplitude and ...

A high-energy signal lasting over seven hours, first observed in mid-2025, has drawn intense scrutiny from astrophysicists tracking rare cosmic phenomena. Detected by multiple space-based ...

The agency’s 31% year-over-year surge in AI use cases includes work with predictive models and surveillance technologies that sparked concern from privacy and technology safety advocates.

A new analysis from the SCOPE consortium evaluates stroke prevention and atrial fibrillation risk after PFO closure in young ...

Technologies like ARM’s Ethos Neural Processing Units (NPUs) offer more power-efficient AI acceleration than general-purpose CPUs. While they add design complexity, they reduce long-term costs by ...

Heart failure (HF) is a chronic and progressive cardiovascular condition associated with significant morbidity, mortality and ...

A machine learning model incorporating functional assessments predicts one-year mortality in older patients with HF and improves risk stratification beyond established scores. Functional status at ...
