Preferable academic work forms of medical students in the era of digitalization

The article presents the sociological study results on the preferred forms of medical students’ academic work in the era of digitalization. The study was carried out among students of the Volga Research Medical University using an online survey. The study purpose is to identify the attitude of various typological groups of medical students to various forms and methods of scientific and methodological support of the educational process, including the use of digital technologies. The work showed that behind the variety of medical students’ attitudes on the effectiveness of different forms of education, there is a willingness of young people to move away from traditional methods of obtaining professional knowledge and skills, and they clearly have a complex request for new forms of teaching, including using the Internet and electronic resources. The assessment of various forms and teaching methods has noticeable differences depending on the affiliation of students to various faculties. The article analyzes the students’ assessments of the various forms’ effectiveness of education using multidimensional data analysis, which made it possible to identify four types of student attitudes: 1) orientation to online learning; 2) live contact with the teacher; 3) electronic library; 4) work with summaries of educational materials. Each of these types contains its own set of preferred and rejected item

Simple model of complex dynamics of activity patterns in developing networks of neuronal cultures

Living neuronal networks in dissociated neuronal cultures are widely known for their ability to generate highly robust spatiotemporal activity patterns in various experimental conditions. These include neuronal avalanches satisfying the power scaling law and thereby exemplifying self-organized criticality in living systems. A crucial question is how these patterns can be explained and modeled in a way that is biologically meaningful, mathematically tractable and yet broad enough to account for neuronal heterogeneity and complexity. Here we propose a simple model which may offer an answer to this question. Our derivations are based on just few phenomenological observations concerning input-output behavior of an isolated neuron. A distinctive feature of the model is that at the simplest level of description it comprises of only two variables, a network activity variable and an exogenous variable corresponding to energy needed to sustain the activity and modulate the efficacy of signal transmission. Strikingly, this simple model is already capable of explaining emergence of network spikes and bursts in developing neuronal cultures. The model behavior and predictions are supported by empirical observations and published experimental evidence on cultured neurons behavior exposed to oxygen and energy deprivation. At the larger, network scale, introduction of the energy-dependent regulatory mechanism enables the network to balance on the edge of the network percolation transition. Network activity in this state shows population bursts satisfying the scaling avalanche conditions. This network state is self-sustainable and represents a balance between global network-wide processes and spontaneous activity of individual elements

Interpretation of percolation in terms of infinity computations

In this paper, a number of traditional models related to the percolation theory has been considered by means of new computational methodology that does not use Cantor's ideas and describes infinite and infinitesimal numbers in accordance with the principle `The part is less than the whole'. It gives a possibility to work with finite, infinite, and infinitesimal quantities numerically by using a new kind of a computer - the Infinity Computer - introduced recently in by Ya.D. Sergeyev in a number of patents. The new approach does not contradict Cantor. In contrast, it can be viewed as an evolution of his deep ideas regarding the existence of different infinite numbers in a more applied way. Site percolation and gradient percolation have been studied by applying the new computational tools. It has been established that in an infinite system the phase transition point is not really a point as with respect of traditional approach. In light of new arithmetic it appears as a critical interval, rather than a critical point. Depending on "microscope" we use this interval could be regarded as finite, infinite and infinitesimal short interval. Using new approach we observed that in vicinity of percolation threshold we have many different infinite clusters instead of one infinite cluster that appears in traditional consideration.Comment: 22 pages, 7 figures. arXiv admin note: substantial text overlap with arXiv:1203.4140, arXiv:1203.316

CENTRO DE INNOVACIÓN TECNOLÓGICA AGROINDUSTRIAL - VALLE DEL COLCA - AREQUIPA

El valle del Colca es reconocido más por sus atractivos turísticos que por sus actividades agropecuarias, pese a la gran influencia que tiene esta actividad sobre la economía y vida del poblador local. Es un lugar que brinda múltiples alternativas de desarrollo para el sector agropecuario, oportunidades que de ser aprovechadas pueden sacar de la pobreza y mejorar la calidad de vida de su población. La presente tesis es una contribución al desarrollo del valle. A través del “Centro de innovación tecnológica agroindustrial valle del Colca” se propone un equipamiento donde las actividades de educación, investigación, producción y difusión mejoren de una forma alternativa y radical las actividades agrícolas del valle. Generando así verdadero bienestar y desarrollo a la población local

On the Localization of the Azak Mosques on the Basis of Epigraphic Finds

The paper provides data on findings, the analysis of which complements the topography of the Golden Horde city of Azak, indicating the locations of several mosques in its territory. The scarce information from written sources, represented by the works of Ibn-Battuta and Josaphat Barbaro, does not provide a basis for an accurate localization. Archaeological materials come to the rescue. Among them are fragments of stone paste and clay tiles, fragments of mosaics, as well as carved stone slabs, glass lamps, and marble mortars. The finds are concentrated in several locations within the city, some of them accompanying the excavated foundations of the walls and minaret towers. An important role is assigned to specimens of architectural decoration containing inscriptions. The paper features the first translation of the Arabic texts found on the inscriptions. It serves as an additional confirmation of the proximate location of Muslim cult structures. As a result of mapping the finds and excavated parts of the buildings, five places were identified in different parts of the city, where a mosque or madrasah very likely existed

Floristic Phenomena of the Samara Bend: The Fractal Organization of Taxonomic Diversity

Considering the problem of taxonomic diversity as a fractal object is the aim of this article. The prerequisites for such an approach were articles with varying degrees of detail and argumentation that substantiate taxonomic diversity from the standpoint of fractal geometry. Common to these papers is that the authors in their theoretical constructs start from the Willis rule (law) describing the rank distribution of the relationship between the number of taxa and their volume. The flora of the Samara Bend (the bend of the Volga River in its middle reaches) has become an object of the research. The authors distinguish seven basic floristic areas on the Samara Bend, the boundaries of which coincide with the respective landscapes. The authors discuss the efficiency of the Willis rule (law), which approximates the relationship between the number of taxa and their volume by rank distribution. The multifractal spectrum (a generalized geometric image of generic structure) of the taxonomic diversity of vascular plants of the Samara Bend is presented. Keywords: taxonomic diversity, fractal organization, Samara Ben
