Parametric decay instabilities frequently occur in wave interactions.These instabilities typically have thresholds for wave amplitudes. They arise when nonlinearity, such as a spatial pressure inhomogenety, couples different waves. For these instabilities to arise, the waves must satisfy frequency and wavenumber matching conditions, which followfrom the laws of energy and momentum conservation. However, parametric instabilities are not limited to wave interactions; the simples form of parametric instability is parametrically coupled oscillators.Magnetoactive plasma represents a unique wave medium in whichnumerous waves of various polarizations and spatial-temporal scales are easily excited and weakly damped. The greater the number of wave types, the easier it is to satisfy resonance conditions like the frequency and wavenumber matching conditions, and thus parametrically excite, or "drive" new waves from the initial wave. Therefore, inmagnetoactive plasma, all known types of parametric instabilities can arise.

This article is the seventh part of the scientific project under the general title "Geometrized Vacuum Physics Based on the Algebra of signature" [1,2,3,4,5,6]. In this article, the metric-dynamic model of two simplest mutually opposite stable spherical vacuum formations is considered - "electron" and "positron". These stable vacuum formations are an integral part of the hierarchical cosmological model proposed in the previous article [6]. The methods of geometrized vacuum physics and the mathematical apparatus of the Algebra of Signature used in this article to study the metric-dynamic model of "electron" and "positron" are suitable for studying all other more complex stable vacuum formations of the same scale: "quarks", "nucleons", "mesons", "atoms" and "molecules", etc., as well as all stable vacuum formations of any scale, for example, "planets", "stars" and "galaxies". This article examines issues related to deformations and accelerated flows of various vacuum layers inside the "electron" and "positron". Paths for the de-velopment of geometrized vacuum electrostatics are outlined. Some aspects of the "electron"-"photon", "electron"-"positron" and "electron"-"electron" interactions are considered. The "electron" and "positron" are infinitely com-plex vacuum formations, but the algorithms and mathematical techniques of the Algebra of signature proposed in the article can allow permanently pushing back darkness into the abyss of the unknown, gradually transforming transcendence into immanence.

The electron represents one of the most exciting and important particles in atomic science. Electrons are very small and mobile fundamental (or elementary) particles that engage in orbitals around atomic nuclei, or can move as an electric current through a conductor, or can spectacularly jump en masse through dielectric material in the form of lightning or an electric arc. They are also important in atomic bonding and chemical reactions. Electric current is usually understood to be caused by the movement of electrons, but electric charge carriers aren't always electrons, and they aren't always negative. In animals (including humans), electric charge carriers are primarily sodium, potassium, calcium, and magnesium ions, which are all positively charged, and when a nerve passes an electric signal, it consists of positive charge movement. For semiconductors, electric current cannot be fully explained simply in terms of the movement of electrons (the negative charge carrier), and a positive charge carrier is required.With like-charges repelling and opposite-charges attracting, we treat negative electric charge as being distinctly different to positive electric charge, or at least that the electric fields associated with each type of charge to be different. This paper considers what electric charge and associated electric fields might consist of, and attempts to explain the reasons why the positive and negative fields of electric charges interact with each other as they do.In terms of like-pole repulsion and opposite pole attraction, magnetic fields are quite similar to electric fields, and are inter-related as implicit in the term ‘electromagnetic’. This paper looks at several models for the electron and its role in electric currents, and explores the nature of and differences between electric and magnetic fields with reference to the STEM electron model.

This paper provides some supplements and revisions to our previous paper titled "New Circular Periodic Table of Elements and Natural Group Theory" (viXra:2401.0001). A subtle revision of circular periodic table of elements is to make 5f small circle (sub-period) not contact to 7sp big circle (main period)，and hence indicates that the 89th element Ac* belongs to 6d elements and the 90th element Th* is the beginning of 5f elements. With this revision, we illustrate the relationships between the stable numbers in nuclides and 2π or π elements, highlight the characteristic numbers of 141, 157 and 173 in f periods and present some proofs in terms of chemical properties for the 70th element Lu to be the end of 4f elements and for the 90th element Th* to be the beginning of 5f elements. We also illustrate the relationships between the characteristic number 112/137/168 and 141/157/173. By the way, we suggest suitable Chinese names for the 117th and 118th element Ts* and Og*.

It is shown that relativity predicts a variable G. The proof starts by considering a dimensionless particle in an empty universe. Then two particles, three particles, and an infinite set of particles are studied. This allows to calculate space-time structure for any realistic energy distribution. The proof uses the interchange of limits theorem, and ad hoc sequences of energy distributions. With only one particle, the result is a singularity everywhere if the universe is empty outside of the particle. Those singularities disappear completely with three particles. Then this calculation is done for any realistic energy distribution. An equation of G is given naturally in the process. This equation is a correct approximation in most of the realistic energy distributions. The fundamental principles building Einstein equation are still valid. But it is shown that the G anthropocentric solar system constant must be replaced by a variable value, which is weaker in strong matter density environments, and greater in low matter density environments. It means that the surrounding effect arises, it was introduced by previous works. And this effect was shown to solve the gravitational mysteries of today in astrophysics and in cosmology. Under a unifying relevant assumption, a solution is also given to the Yang-Mills Millennium problem.

This paper is a brief review of our previous papers concerning 2π-e formula, formulas of the fine-structure constant, formulas of the speed of light in atomic units and formulas of the anomalous magnetic moments of electron, muron and tauon. In this paper, these formulas are mainly elucidated from points of view of their relationships with 2π and e so as to answer the physicist Feynman’s question whether the fine-structure constant was related to π and e. In addition, we also give some new formulas of the fine structure constant and the speed of light in atomic units, especially a formula of a half of the speed of light in atomic units incorporating three factors of 141, 173 and 157, which are related to values of square root of 2, square root of 3 and π/2 in atomic units respectively.
