Analises the notion “loneliness” as socio-cultural phenomena

This article describes different approaches to the understanding of loneliness in social sciences and humanities. The main aim is to explore the difference of understanding, for describing the main common features of loneliness. The three observes approaches are: philosophical, psychological, sociological. Conclude: loneliness is a widespread modern phenomen, which have no cultural, religious and geographical boundarys. For modern people loneliness is an urgent need. It allows to reach maturity.Данная статья описывает различные подходы к пониманию одиночества в социальных и гуманитарных науках. Главная задача – изучить разницу в понимании для дальнейшего описания наиболее важных общих черт одиночества. Три рассмотренных подхода: философский, психологический и социологический. Заключение: одиночество широко распространенный феномен, не знающий культурных, религиозных, географических границ. Современный человек имеет острую потребность в одиночестве. Оно позволяет ему достигать зрелости

The lichen genera Thelidium and Verrucaria in the Leningrad Region (Russia)

Lichens from the genera Thelidium and Verrucaria in the Leningrad Region (including Saint-Petersburg) are revised. Altogether five species of Thelidium and 31 of Verrucaria are confirmed for this region. Four species (Thelidium minimum, T. olivaceum, Verrucaria maculiformis and V. trabalis) are new to the Leningrad Region, and 17 species (Thelidium aphanes, T. fontigenum, Verrucaria christiansenii, V. elevata, V. epilithea, V. helsingiensis, V. illinoisensis, V. inaspecta, V. invenusta, V. ligni- cola, V. pilosoides, V. polystictoides, V. pseudovirescens, V. rejecta, V. tectorum, V. tornensis and V. transfugiens) are new to Russia. Dubious records for the Leningrad Region include Verrucaria acrotella, V. floerkeana, V. fusca, V. nigrescens, V. obnigrescens, V. umbrinula and V. viridula.

Understanding oscillons: standing waves in a ball

Oscillons are localised long-lived pulsating states in the three-dimensional $\phi^4$ theory. We gain insight into the spatio-temporal structure and bifurcation of the oscillons by studying time-periodic solutions in a ball of a finite radius. A sequence of weakly localised {\it Bessel waves} -- nonlinear standing waves with the Bessel-like $r$-dependence -- is shown to extend from eigenfunctions of the linearised operator. The lowest-frequency Bessel wave serves as a starting point of a branch of periodic solutions with exponentially localised cores and small-amplitude tails decaying slowly towards the surface of the ball. A numerical continuation of this branch gives rise to the energy-frequency diagram featuring a series of resonant spikes. We show that the standing waves associated with the resonances are born in the period-multiplication bifurcations of the Bessel waves with higher frequencies. The energy-frequency diagram for a sufficiently large ball displays sizeable intervals of stability against spherically-symmetric perturbations.Comment: 13 pages, 12 figure

Structured observation as a method of religious landscape studies

The article presents the results of a study devoted to the Orthodox landscape in Yekaterinburg. A professional reader might be interested in the authors’ innovative methodology to study religious interaction in its contextual and cultural uniqueness. The key element of the methodology is a combination of the ‘thick description’ strategy proposed by Norman K. Denzin and a structured observation in the author’s operationalization. Initially, the proposed consideration of the results of the Yekaterinburg interactive landscape’s ‘thick description’ was intended to be a pilot study of a big research project. However during the implementation phase the authors revealed that the method of ‘thick description’ had never been used as a preliminary stage of survey or exert interview. The provocative character of the paper is that the authors explain in detail the methodology of design and operationalization of the structured items of the observation with regard to a specific object. Structured observation introduced by the authors as a scientific method helps to conduct a similar study in any other city or country. The obtained sociological ‘router’ of Yekaterinburg’s Orhodox landscape is an invitation to a scientific journey towards the design of representative samples for narrow-focused projects. © 2018 Russian Public Opinion Research Center VCIOM.

Terahertz Bloch oscillator with a modulated bias

Electrons performing Bloch oscillations in an energy band of a dc-biased superlattice in the presence of weak dissipation can potentially generate THz fields at room temperature. The realization of such Bloch oscillator is a long-standing problem due to the instability of a homogeneous electric field in conditions of negative differential conductivity. We establish the theoretical feasibility of stable THz gain in a long superlattice device in which the bias is quasistatically modulated by microwave fields. The modulation waveforms must have at least two harmonics in their spectra.Comment: 5 page

Additions to the lichen biota of Berezovye Islands, Leningrad Region, Russia

66 species of lichens, 9 lichenicolous fungi and 4 non-lichenized saprobic fungi are reported as new to the Berezovye Islands (Leningrad Region, Russia). The updated lichen biota of the archipelago comprises 356 species. Caloplaca maritima, Lecanora compallens, Verrucaria boblensis and Xanthoriicola physciae are reported for the first time for Russia, Lecanora aitema – for European Russia, Lecanora semipallida and Lichenodiplis lecanorae – for North-Western European Russia. Absconditella sphagnorum, Chaenothecopsis vainioana, Lempholemma polyanthes and Opegrapha niveoatra are new to the Leningrad Region, Arthonia byssacea and Lecanora subrugosa – to the Western Leningrad Region.

Two and three-dimensional oscillons in nonlinear Faraday resonance

We study 2D and 3D localised oscillating patterns in a simple model system exhibiting nonlinear Faraday resonance. The corresponding amplitude equation is shown to have exact soliton solutions which are found to be always unstable in 3D. On the contrary, the 2D solitons are shown to be stable in a certain parameter range; hence the damping and parametric driving are capable of suppressing the nonlinear blowup and dispersive decay of solitons in two dimensions. The negative feedback loop occurs via the enslaving of the soliton's phase, coupled to the driver, to its amplitude and width.Comment: 4 pages; 1 figur
