To describe the processes of acceleration and transfer of charged particles in turbulent magnetospheric and solar plasmas, a two-dimensional model of a turbulent electromagnetic field with a controlled intermittency level is proposed. In the model, the electromagnetic field has two components: a turbulent electromagnetic field obtained in the form of a superposition of plane waves, and an electromagnetic field created by oscillating magnetoplasma structures—plasmoids. Within the framework of the model, the role of intermittency in the acceleration of charged particles is investigated. It is shown that, the larger the parameter characterizing the level of intermittency, the higher the energy values that the charged particles are able to reach. The use of the model for describing observations of high-energy particle fluxes in the Earth's magnetosphere and in the solar wind is discussed. [ABSTRACT FROM AUTHOR]

It is believed that microscopic life is possible in the subglacial ocean of Europa, a satellite of Jupiter. However, Jupiter's radiation belts make it difficult to detect it on the surface or at shallow depths. Using numerical simulations, we investigated the influence of the inclination of the magnetic dipole of Jupiter, the Alfvén wings, and the induced field of Europa on the dynamics of electrons near the satellite of Jupiter, which made it possible to refine the map of radiation doses on Europa's surface, obtained earlier in the approximation of the guiding center.

The assertion that social upheaval tends to coincide with peaks of solar activity is the main result of A.L. Chizhevskii's first famous work, published in 1924. The connection between solar activity and averaged indicators of the collective human mental state has since then been repeatedly verified by independent authors on various datasets and confirmed with certainty. However, all patterns revealed to date concern small spatial (about the size of a city) and huge time (about 10 years) scales of this correlation between solar activity and indicators of human mental states. In our research we attempt to extend proof of this correlation to a much smaller time scale and a much larger spatial scale. The effect of geomagnetic activity on the human nervous system is studied through investigating its correlation with frequencies of emotion-laden words in a database of posts from the scientific forum dxdy.ru in the years 2006–2016. A subset of emotion-laden words whose relative frequency correlates with the Kр-index at a level r = 0.4–0.6 with p < 0.0001 (p being the probability of obtaining a sample correlation coefficient of 0.4–0.6 if the true correlation between the series is zero) is identified.
