Keywords: Mie theory, high-order Fano resonance, mesoscale spherical particle, mesotronics, superresonance, giant magnetic field
Although the Mie theory was created about 120 years ago, most of the discoveries made during the last 30 years can be described on the basis of this theory (photon jet, Fano resonance, optical anapoli, optical vortices, acoustic jet). They were "encoded" in the Lorenz-Mie formulas and were just waiting for someone to decipher them. The article briefly discusses a new effect - superresonance (and the accompanying Fano resonance of an extremely high order), which describes the scattering of light by spherical particles. Superresonance could also have been discovered as early as in 1908 and its basic physics can also be explained using the Mie theory. However, this effect remained hidden inside the exact Mie solution for almost 120 years!

Keywords: water vapor, LED-based Fourier transform spectroscopy, energy levels, vibrational-ratational transitions
Fourier absorption spectrum of water vapor is studied in the spectral region 14800-15500-1 with a resolution of 0.05 cm-1 and an optical path length of 3480 cm. A detailed list is obtained consisting of 906 identified absorption lines of H216O, as well as a set of 426 energy levels belonging to 19 vibrational states. Fifty-five energy levels are determined for the first time, and the energies of 64 levels are corrected. A comparison is made with the data available in the literature. The error in the positions of well-resolved not very weak lines is 0.002 cm-1, and the error in intensities is 10-15%.

Keywords: IR spectrum, carbon dioxide, dimers (СО), spectral line wings
Absorption due to (СО2)2 dimers is estimated as the difference between the experimental CO2 absorption and that calculated on the basis of the asymptotic line wing theory. This procedure successfulness depends on the quantity and quality of the given experimental data. Available absorption data on the absorption within the 4.3 and 15 mm СО2 bands do not satisfy in full these requirements. However the qualitative agreement of the dimer absorption obtained with the measured and calculated positions of the (СО2)2 bands allows one to say about the procedure as about additional way of estimate absorption of the stable dimers of the H2O and CO2 molecules important for the atmospheric IR absorption.

Keywords: microparticle, laser radiation, heating, laser breakdown, thermal emission, conductivity, microwave reflection
Physical processes occurring in aerodisperse media with solid particles in a laser channel during thermal emission of electrons from the particle surface and primary optical breakdown are considered. Estimates of the change in the refractive index during the formation of plasma halos around radiation-heated microparticles are given. The possibility of weak ionization of the air medium at a distance of several centimeters from the breakdown site is shown, due to the ionization of NO molecules and the course of a number of thermochemical reactions.

Keywords: Arctic, atmosphere, aerosol, air, vertical distribution, transport, impurity, number concentration, chemical composition
This work presents the analysis of the spatial distribution of number concentrations, size distribution, and chemical composition of aerosol particles measured for the first time over the seas of the Russian Arctic. Various types of vertical distribution of the number concentration were recorded, characteristic of both coastal marine and continental areas. Most of them turned out to be of the continental type. Attention is also drawn to the almost complete absence of coarse particles above 2-3 km over all seas. The chemical composition of the Arctic aerosol at altitudes of 200 m 5000 m contains ions that can be attributed to both marine and continental. The identifiable non-carbon elemental part of the aerosol (without ions) over the Arctic is 3-4 times larger than the at for ions. Over all seas and at both altitudes, the Arctic aerosols mainly contain elements of terrigenous origin - Al, Cu, Fe, Si. Over almost all seas, except the Barents Sea, Si dominates in the elemental composition of the aerosol, its contribution over the Chukchi Sea reaching 85%. The analysis of backward trajectories showed that in all cases considered, whether the aerosol was formed over the continent or sea, air trajectories passed both over sea and over land. In this case, the formed particles could be enriched with additional ions and elements along the way.

Keywords: measurement problem, quantum (anti-)fundamentalism, Bohr, contextual quantum realism
According to one of the possible diagnoses of the quantum measurement problem, it is a consequence of quantum fundamentalism, which claims that ontology and epistemology of the world are exclusively quantum, and classical physics is only an approximation. For N. Bohr, the problem of measurement is a pseudo-problem, since any quantum phenomenon presupposes a classical context of an experimental unit and the use of classical concepts to describe it. We consider Bohr’s position in terms of our contextual quantum realism (QCR), which is inspired by the philosophy of the later Wittgenstein. Our approach is consistent with H. Zinkernagel’s interpretation, which is that Bohr’s position is not only epistemological anti-fundamentalism, but also ontological anti-fundamentalism.

The term “artificial intelligence winter” was coined by analogy with the term “nuclear winter” to describe the chain reaction caused by experts’ pessimistic forecasts and resulting in a drastic decline in AI research. Later on, the term “AI winter,” influenced by the concept of “hype cycle,” began to describe the investment cycle of AI research and only became stronger with coining the term “AI spring” as a synonym for “AI boom.” Over the past few years, several researchers have been predicting an AI winter and warning of potential problems following the “peak of inflated expectations.” However, a more thorough analysis shows that predicting an AI winter does not take into account some factors, the key ones being institutional and economic, as well as ignores the fundamentally different approach of modern society to AI research. This means that even with the advent of “AI November,” the winter of basic AI research will not come in the near future.

In the Modern era, the accumulation and development of knowledge acquired through new theoretical and experimental approaches to understanding the processes occurring in the body continued, and important discoveries were made. At present, blood physiology is one of the important sections of physiology. The article is aimed at identifying and characterizing the main periods of formation and development of blood physiology. The materials for this work were domestic and foreign studies on the issue. The main results consist in presenting the stages of the development of blood physiology and featuring the contributions of leading researchers in this field. The conclusion is made about the process of formation and development of blood physiology as a branch of medical and biological knowledge.

Keywords: higher education, university, educational cluster, ecosystem approach, innovative educational ecosystem, tracks of innovative development
The article proposes an ecosystem approach as the basis of the methodology for de-signing a university educational cluster in an emerging innovative society. The ontology of the development of university educational structures is represented as a self-developing cluster system whose principles of functioning are modeled using the ecosystem approach. The design principles for restructuring the university education system are presented at two levels: the university and its developing structure are modeled as a transdisciplinary cluster system, and the structural and functional dynamics is represented as a self-organizing system that adapts to a changing external environment. The methodology for solving the problem is revealed through key concepts and methods: the goal and purpose of the eco-system, the main activity process, the structure of the ecosystem and its elements, the educational environment, the management system, the product of the ecosystem, as well as the process of formation and self-development of educational structures of the ecosys-tem as a socio-cultural phenomenon.
The article provides a review of the book “Epistemology: An Introduction to the Theory of Knowledge” by Nicholas Rescher and contains a summаry of the main ideas of each chapter.
