Изменение спектра аврорального километрового радиоизлучения при распространении в неоднородной космической плазме
Известия РАН. Серия физическая. 2024. Т. 88. № 3. С. 451–456.
We have analyzed characteristics of electric components of the auroral kilometric radiation (AKR) detected onboard of two satellites, in the Earth’s inner magnetosphere (ERG) and in the solar wind (WIND). It is shown that spectra are modified as the result of AKR the propagation in plasma channels — high frequencies are suppressed. The computer simulation confirms experiments.

Numerous studies have provided compelling evidence that the probability distribution of avalanche sizes follows a power law, and that 1/f noise is present in the stochastic dynamics of landslides. We present a theoretical explanation of these phenomena within the framework of self-organized criticality theory, proposing a discrete-time model in the form of a sandpile cellular ...

A discrete-time model is presented for the self-organization of the X/Twitter social network to the edge of a phase transition, characterized by avalanche-like propagation of information in the network. The model is based on the analogy between the critical dynamics of the X social network and sandpile cellular automata with Manna rule on the Chung-Lu ...

Superconducting properties of metallic micro- and nanowires can be entirely different from those of bulk superconductors. Of particular interest is the nonequilibrium current-induced state of a quasi-one-dimensional superconducting channel. The most interesting phenomenon here is the stepped I–V characteristic, explained by a process known as phase slip center activation. If the origin of such step-like ...

Machine learning (ML) has become a powerful tool for accelerating the development of carbon-based supercapacitors;
however, most published models assume that a single predictive framework can describe both conventional
porous carbons and hybrid carbon electrodes. Here, we test this assumption using a comprehensive
benchmark dataset and an extended literature-curated dataset enriched with synthesis- and electrolyte-related
descriptors. Three ML algorithms ...

This paper compares the ranging precision of direct time-of-flight (dToF) and non-line-of-sight (NLOS) LiDAR architectures, both using a superconducting nanowire single-photon detector (SNSPD). Both systems operate at 1550 nm with a 50 ps pulsed laser and time-correlated single-photon counting (TCSPC). The dToF configuration achieved approximately 100 µm precision at 10 m, while the NLOS configuration achieved 500 µm precision for ...

Manufacturing precise quantum computers with small errors in quantum operations, long coherence times, and low power consumption is the most important challenge in modern nanoelectronics. To understand the operating modes of such calculators in detail, both the optimal arrangement of the qubit system within the structure and changes in its magnetic properties must be comprehensively ...

The ERG (Arase) satellite recently discovered a non-thermal hectometric continuum with a narrowband frequency structure. The mechanism behind the generation of this type of emission in the near-Earth plasma is still unknown. This study examines the potential use of electron cyclotron harmonics instability to explain the line structure of hectometric radio emissions for the first ...

We present the results of Auroral Kilo-metric Radiation (AKR) measurements near the plasmapause on the ERG (Arase) satellite. The apogee of the satellite's orbit is located near the ecliptic plane, at latitudes ±30°. According to the generally accepted point of view, AKR observation is impossible in this region since it is shielded by the plasmasphere. ...

Представлены результаты статистической обработки измерений аврорального километрового радиоизлучения, зарегистрированного на спутнике WIND вблизи точки либрации L1. Показано, что частота регистрации аврорального километрового радиоизлучения изменяется в противофазе с вариациями солнечной активности. Сделано предположение, что такое изменение частоты регистрации аврорального километрового радиоизлучения связано с особенностью распространения радиоизлучения в неоднородной плазме солнечного ветра. ...

Above the sunlit surface of Mercury, the properties and formation of dusty plasmas are investigated. It is demonstrated that the dusty plasmas are formed for subsolar angles exceeding approximately 76^o due to photoelectric and electrostatic processes. As a result, the dusty plasmas are present in the polar regions of Mercury, characterized by latitudes of about 70^o and above. The formation ...

Observations are reported of electromagnetic emissions at frequencies above the electron gyrofrequency in a mirror-confined electron cyclotron resonance plasma. These emissions are interpreted as the excitation of the fast extraordinary wave at the fundamental harmonic of the electron gyrofrequency, similar to the excitation of the auroral kilometric radiation (AKR) of the Earth. The paper proposes ...
