A sun sensor implemented with an asynchronous luminance vision sensor [PDF]
, 2017 A sun sensor implemented with a spiking pixel matrix is reported. It is the very first one based on an asynchronous event-based pixel array. A paradigm associated to classic digital sun sensors is solved with this approach. Only pixels illuminated by the

The Centaurus Group and the Outer Halo of NGC 5128: Are they Dynamically Connected? [PDF]
, 2006 NGC 5128, a giant elliptical galaxy only $\sim 4$ Mpc away, is the dominant member of a galaxy group of over 80 probable members. The Centaurus group provides an excellent sample for a kinematic comparison between the halo of NGC 5128 and its surrounding

Contemporary Icarus: Gustav von Aschenbach’s Journey towards the Sun
Czytanie Literatury, 2020 The point of departure for the reflections contained in this article is the motif of the sun in Tomasz Mann’s Death in Venice. Analysing the presence of the sun in the work turns out to be fruitful for distinguishing and connecting several symbolic ...

Sudden transitions and grand variations in the solar dynamo, past and future☆
Journal of Space Weather and Space Climate, 2012 The solar dynamo is the exotic dance of the sun’s two major magnetic field components, the poloidal and the toroidal, interacting in anti-phase. On the basis of new data on the geomagnetic aa index, we improve our previous forecast of the properties of ...

Influence of cosmic factors on mud volcanic activity of the Earth [PDF]
Геосистемы переходных зон, 2023 In this work, the influence of various cosmic factors (gravitational influence of the Moon and the Sun, solar activity, the Earth’s rotation) on mud volcanic activity was analyzed for the first time. The analysis was carried out mainly on the example of

Melanoma Epidemiology and Sun Exposure
Acta Dermato-Venereologica, 2020 The worldwide incidence of melanoma has increased rapidly over the last 50 years. Melanoma is the most common cancer found in the young adult population, and its incidence is very high among geriatric populations. The incidence of melanoma varies by sex,

The fine structure of the rotational periods of the solar mean magnetic field
Open Astronomy, 2021 The data of mean magnetic field (MMF) of the Sun obtained at the Wilcox Solar Observatory (Stanford, USA) in 1975–2020 are analysed. It was concluded that the MMF maximum occurs, on average, 1.5–2 years later relative to the maximum of Wolf numbers.

The Sun’s Supergranulation [PDF]
Living Reviews in Solar Physics, 2010 Supergranulation is a fluid-dynamical phenomenon taking place in the solar photosphere, primarily detected in the form of a vigorous cellular flow pattern with a typical horizontal scale of approximately 30--35~megameters, a dynamical evolution time of 24--48~h, a strong 300--400~m/s (rms) horizontal flow component and a much weaker 20--30~m/s vertical
