Self-supervised learning (SSL) has recently emerged as a promising paradigm for training generalisable models on large-scale data in the fields of vision, text, and speech. Although SSL been proven effective speech audio, its application to music audio yet be thoroughly explored. This is partially due distinctive challenges associated with modelling musical knowledge, particularly tonal pitched characteristics music. To address this research gap, we propose an acoustic Music undERstanding...

The main aim is identify an optimal height range, if any, in interface region between photosphere and lower corona, where onset time capability WG best exploited. prediction, by means method, achieved earlier than at photospheric level. 3D structures, based on potential...
The Solar Activity Magnetic Monitor (SAMM) Network (SAMNet) is a future UK-led international network of ground-based solar telescope stations. SAMNet, at its full capacity, will continuously monitor the Sun’s intensity, magnetic, and Doppler velocity fields multiple heights in atmosphere (from photosphere to upper chromosphere). Each SAMM sentinel be equipped with cluster identical telescopes each different magneto-optical filter (MOFs) take observations K I, Na D, Ca I spectral bands. A...

Jets, whatever small (e.g. spicules) or large macrospicules) their size, may play a key role in momentum and energy transport from photosphere to chromosphere at least the low corona. Here, we investigate properties of abundant, large-scale dynamic jets observable solar atmosphere: macrospicules (MS). These are observationally more distinct phenomena than little, perhaps ubiquitous, cousins, spicules. Investigation long-term variation help better understanding underlying physics generation...

The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) has observed more than 80,000 solar energetic events since its launch on February $12^{\rm th}$, 2002. Using this large sample of flares, we studied the spatio-temporal relationship between succeeding flares. Our results show that statistical temporal and spatial differences flares can be described as a power law form $R(t)\sim t^p$ with $p=0.327\pm 0.007$. We discuss possible interpretations result characteristic function...
