Radio Measurements of the Magnetic Field in the Solar Chromosphere and the Corona
Frontiers in Astronomy and Space Sciences, 2021 The structure of the upper solar atmosphere, on all observable scales, is intimately governed by the magnetic field. The same holds for a variety of solar phenomena that constitute solar activity, from tiny transient brightening to huge Coronal Mass ...

Signatures of Magnetic Flux Ropes in the Low Solar Atmosphere Observed in High Resolution
Frontiers in Astronomy and Space Sciences, 2019 Magnetic flux ropes (MFRs) are important physical features closely related to solar eruptive activities with potential space weather consequences. Studying MFRs in the low solar atmosphere can shed light on their origin and subsequent magnetic structural

SUN database: Large-scale scene recognition from abbey to zoo
2010 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2010 Scene categorization is a fundamental problem in computer vision. However, scene understanding research has been constrained by the limited scope of currently-used databases which do not capture the full variety of scene categories.
