The work investigates spatial and temporal EEG patterns during real and imagined execution of hand reaching. Six independent sources of electrical activity were identified in the EEG recordings. The sources corresponded to the premotor areas, supplementary motor area, primary motor areas, and posterior parietal cortex. Their activation patterns in the alpha and beta range were ...

We examine the time-frequency co-movements and return and volatility spillovers between the rare earths and
six major renewable energy stocks. We employ the wavelet analysis and the spillover index methodology from
January 1, 2018 to May 15, 2020. We report that the COVID-19-triggered significant increase in co-movements
and spillovers in returns and volatility between the rare earths and ...

The wavelet approach covering simultaneously the time and frequency domains is employed to study the impact of the Covid-19 coverage in mass media on the performance of the Dow Jones Sukuk investment grade total return indices. The overall coherence level for the media-coverage – sukuk pairs is found to increase with the investment horizon. Multiple ...

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 ...

Up to now a Distributed optical fiber Temperature Sensor (DTS) based on the
Raman scattering exhibits a relatively low characteristic causes sharp
temperature changes to be improved. Modeling metrological characteristics has
a long history but essential progress did not achieved. This paper presents
a novel technique of the extremal filtration developed to improve the DTS
temperature and partially spatial resolution. ...

A method is proposed for the study of the height–time characteristics of physical processes in the
region of auroral electron acceleration. Auroral kilometer radiation, which is generated at the local electron
gyrofrequency, can be used to obtain the height distribution of the properties of a radiation source in the auroral
region, and long-term satellite measurements of the auroral ...

The current work is devoted to study of interrelations of the obtained time series by means of econometric and wavelet analysis. At the first stage of this study, econometric analysis was conducted, regression was constructed. In the regression influence of the number of nomads and the amount of resource on the number of plowmen was studied. The ...

This work presents the microwave long-term oscillations with periods of a few tens of minutes obtained from Nobeyama radioheliograph (NoRH) at frequency 17 GHz. In two active regions the fluctuations of radio emission of different types of intersunspot sources (ISS) (compact and extended) were compared with the fluctuations in magnetic fields of sunspots. Common periods ...

Long-term oscillations of microwave emission generated in sunspot magnetospheres are detected with the Nobeyama Radioheliograph (NoRH) at a frequency of 17 GHz, and the Siberian Solar Radio Telescope (SSRT) at 5.7 GHz. Significant periodicities in the range of 22–170 min are found in the variation of the emission intensity, polarisation and the degree of circular polarisation. Periods of ...
