Development of a new approach to data analysis of complex systems: Study of synchronization in the dynamics of solar activity parameters
(2021) Yunusov, V. A.; Demin, S. A.; Demina, N. Y.; Timashev, S. F.; Тимашев, Сергей Федорович
© 2021 IEEE.In this paper, we develop a new approach to the study of matching and mismatching effects in simultaneously recorded time signals characterizing the evolution of natural systems. We discuss the challenges of developing methods of intellectual data analysis of data generated by complex composite objects. In the framework of basic provisions and concepts of Flicker-Noise Spectroscopy, we study the frequency-phase synchronization in the dynamics of Wolf numbers and coronal solar ejections. The evolution of collective processes in the solar atmosphere is represented by changes in the shape of the cross-correlators. We calculated the quantitative structural parameters of cross-correlators to assess causal relationships between the parameters of solar activity. The established levels of cross-correlations in thermodynamically open distributed systems, such as the Sun, can become an object of standardization. The combination of Flicker-Noise Spectroscopy with mathematical models and machine learning software will allow advancing in understanding the collective phenomena realized in complex systems.

Variations in Cosmic Rays before Powerful Earthquakes
(2021) Borog, V. V.; Timashev, S. F.; Борог, Владимир Викторович; Тимашев, Сергей Федорович
© 2021, Allerton Press, Inc.Abstract: It is found that variations in cosmic ray fluxes are observed before powerful earthquakes (magnitude M ≈ 8) at most neutron monitors of the world network located on different continents. Reliable data obtained via flicker-noise spectroscopy are recorded several days before earthquakes and can serve as the basis for creating a predictor of the first level.

АНАЛИЗ ВЛИЯНИЯ ИОННО-КЛАСТЕРНОЙ ОБРАБОТКИ НА СОСТОЯНИЕ ПОВЕРХНОСТИ ОПТИЧЕСКОЙ СТЕКЛОКЕРАМИКИ МЕТОДОМ ФЛИККЕР- ШУМОВОЙ СПЕКТРОСКОПИИ

A method of parameterization of supersmooth surfaces used in micro- and nanoelectronics as substrates and light-reflecting elements is proposed. The method is based on the flicker-noise spectroscopy (FNS) as the general phenomenological approach to extracting information from the chaotic temporal or spatial signals. The glass-ceramic samples were processed by cluster-ion beams and their topology was investigated by atomic force microscopy before and after treatment. It is established that gas cluster ion beams processing of glass ceramics leads to angstrom-level surface roughness.

Atom As an Open Dissipative System in the Basic Environment–the Electromagnetic Component of a Physical Vacuum: Phenomenology
(2022) Timashev, S. F.; Тимашев, Сергей Федорович
Abstract: Based on ideas developed by the author about the vacuum of an electromagnetic field (the EM vacuum as a basic system of reference and the Casimir polarization of the EM vacuum near electrons and atomic nuclei) it is shown that the genesis of the irreversibility of real processes in time—the “arrow of time”, as one of the “great problems of modern physics” (according to V.L. Ginzburg)—lies in the inevitability of dissipative processes at all spatiotemporal levels of the hierarchy of natural systems. Dissipation accompanies all processes, from macroscopic—in the dynamics of which irregularities of a chaotic nature inevitably appear—to those at the level of atoms and atomic nuclei, since energy must be supplied from the EM vacuum even to maintain the functionally active state of the electronic subsystem of the atom and the nuclear matter of the atomic nucleus. This occurs in the non-equivalent exchange of energy between the virtual photons of the EM vacuum and the region of the Casimir polarization of the electronic subsystem of an atom or atomic nucleus. Within such representations, the Universe itself is an open system fed with energy from the energy-saturated world environment—the proto-vacuum. Phenomenological ideas about the dynamics of the Universe that are developed in this work allow us to solve the most acute problems of such dynamics in a natural way, along with that of the so-called cosmological constant, and to establish the relationship between this constant, which characterizes the expansion of the Universe, and the energy density of the EM vacuum. The introduced concepts allow us to understand a number of other unsolved problems connected in one way or another with the key role of virtual photons in a number of optical phenomena. This is true in particular for the mysterious phenomenon of no light scattering from distant stellar sources, manifested most clearly in the fixed independence of the surface brightness of similar galaxies from their redshifts, which cannot be understood on the basis of the Huygens–Fresnel principle. It has also been shown that the recently established effect of “mass being attracted by a light flux” is due to the accumulated energy of virtual photons produced by the intense light flux in the near-surface regions of massive objects. The subsequent re-emission of light can in this case determine the so-called lensing effect observed in astrophysics, which is usually considered as associated with the effect gravity has on light fluxes. © 2022, Pleiades Publishing, Ltd.

On the Physical Nature of Quantum Mechanics and Gravitation: Phenomenology
(2022) Timashev, S. F.; Тимашев, Сергей Федорович
Abstract: An attempt to solve the general problems concerning the physical essence of quantum mechanics formulated by R. Feynman back in 1964 is presented. The proposed phenomenological approach is based on the hypothesis about the electromagnetic component of physical vacuum (EM vacuum) as the basic medium of the expanding Universe and the absolute reference system associated with it, as well as on the idea of Casimir polarization of EM vacuum in the vicinity of atomic nuclei and electrons as systems open to EM vacuum. Due to Casimir polarization, the electron is no longer a point particle, but an EM polaron with a characteristic size of (Formula presented.) = 5.2 × 10–11 cm. The region of Casimir polarization in the vicinity of the proton is (Formula presented.) = 2.8 × 10–14 cm. It is exactly the nonpoint nature of the introduced EM polarons that is responsible for the fact that the apparatus of quantum mechanics is based on the introduced operators for the observed characteristics of particles, but not on the direct use of these characteristics. It was established that within the framework of the introduced concepts, all the operators introduced in the Dirac equation for the electron are consistent with the observed characteristics of electron as a wave–particle. The quantum mechanical tunneling effect was explained as permeation of a wave–particle through a barrier with repulsive centers. The physical essence of the phenomenon of quantum entanglement was considered. It was shown also that gravity is determined by the overlap of Casimir polarization regions of atomic nuclei of two macroscopic objects separated from each other by macroscopic distances up to intergalactic ones. © 2022, Pleiades Publishing, Ltd.

Flicker-Noise Spectroscopy analysis of magnetoencephalogram signals in diagnosis and treatment of photosensitive epilepsy
(2022) Demin, S. A.; Yunusov, V. A.; Timashev, S. F.; Тимашев, Сергей Федорович
© 2022 SPIE.Our study demonstrates the potential of Flicker-Noise Spectroscopy analysis of neuromagnetic brain responses (magnetoencephalograms) in possible diagnosis and estimating the effectiveness of treatment of photosensitive epilepsy. The tendency of the organism to restore the synchronization to its normal levels is considered the cornerstone of the analysis. A two-parameter Flicker-Noise Spectroscopy cross-correlation function is applied to show that the breakdown of frequency-phase synchronization in the magnetoencephalograms of the patient can be associated with two distinct mechanisms: high-frequency resonances (50-100 Hz) at specific brain areas and changes in high-frequency stochastic components for other brain areas. Our analysis also reveals a certain disruption of regular behavior and occurrence of asymmetry in three-dimensional plots of the cross-correlation function for some healthy controls, suggesting that these individuals may be susceptible to photosensitive epilepsy. We believe that a similar cross-correlation analysis based on appropriate biomedical signals may be used to assess the effectiveness of medical treatment for other diseases and conditions.
