Abstract:
The post-Soviet space has seen a large-scale transformation of media markets that is marked with an unprecedented rise of entrepreneurial initiatives across business sectors, including media businesses. This paper analysed the dynamics of Russian media markets and the challenges of Russian media entrepreneurs. The media markets of Russia shifted toward more concentration and fragmentation, and media holdings are continuously gaining more power. This paper also looked at the regional media markets of Russia. According to research, there are less than 20 self-sustainable regional media holdings in Russia due to the low capacity of regional advertising markets. National media holdings have a diversified portfolio consisting of different types of media with a growing fraction of digital media companies, and the regional media lag behind in terms of its digital component. Most regional media holdings operate traditional media. Their digital channels are yet to be developed, despite the chief executives' acknowledgement that the future of revenue streams comes from digital channels.

Abstract:
The Burridge–Knopoff model of earthquake faults with viscous friction is equivalent to a van der Pol–FitzHugh–Nagumo model for excitable media with elastic coupling. The lubricated creep–slip friction law we use in Burridge–Knopoff model describes the frictional sliding dynamics of a range of real materials. Low-dimensional structures including synchronous oscillations and propagating fronts are dominant, in agreement with the results of laboratory friction experiments. Here we explore the dynamics of fronts in elastic excitable media.

Abstract:
Democratization in communication is the starting point for mass media in achieving a prosperous information society. However, building an ideal democratic role of media is not trouble free. The incredible pace of the development of media industry in Indonesia in the last two decades poses at least two main threats to media consumers. First, the growth of the media industry in Indonesia has been driven by capital interests that lead to media oligopoly. Second, the integration of conventional media and the internet and social media technology place our society information flow on a stranglehold. The media consolidation gives the audience an illusion of information choice without realizing that actually they are losing their rights for reliable information. Hence, an upgrade of media literacy skill and a proper media policy are needed to cope with the current fast-paced world.

Abstract:
A wide range of engineering problems involve porous media modeling. General porous media models are highly nonlinear, geometrically complex, and must account for energy transfer between fluid and solid constituents normally modeled in distinct Lagrangian and Eulerian reference frames. Combining finite element discretization techniques with bond graph methods greatly simplifies the model formulation process, as compared to alternative schemes based on weighted residual solutions of the governing partial differential equations. The result generalizes existing numerical models of porous media and current network thermodynamics/bond graph theory.

Abstract:
We propose a dynamic joint sentiment-topic model (dJST) which allows the detection and tracking of views of current and recurrent interests and shifts in topic and sentiment. Both topic and sentiment dynamics are captured by assuming that the current sentiment-topic specific word distributions are generated according to the word distributions at previous epochs. We derive efficient online inference procedures to sequentially update the model with newly arrived data and show the effectiveness of our proposed model on the Mozilla add-on reviews crawled between 2007 and 2011.

Abstract:
Wave dynamics in the coupled FitzHugh–Nagumo oscillators with pacemaker defects is studied. It is found that with increasing the coupling strength, the lattice experiences a dynamical transition from a local wave to the global propagation. For large enough coupling, a transition from global wave propagation to the propagation failure can be observed. Noise-enhanced wave propagation in the propagation-failure regime is revealed.

Abstract:
We investigate the effects of external and autonomous global interaction fields on an adaptive network of social agents with an opinion formation dynamics based on a simple imitation rule. We study the competition between global fields and adaptive rewiring on the space of parameters of the system. The model represents an adaptive society subject to global mass media such as a directed opinion influence or feedback of endogenous cultural trends. We show that, in both situations, global mass media contribute to consensus and to prevent the fragmentation of the social network induced by the coevolutionary dynamics. We present a discussion of these results in the context of dynamical systems and opinion formation dynamics.

Abstract The paper proposes an approach for constructing exact solutions of differential equations of mathematical physics, in particular, the telegraph equation. The method is based on the theory of finite-dimensional dynamics of systems of evolutionary differential equations. This theory is a natural extension of the theory of dynamical systems to partial differential equations. It allows one to construct exact solutions of partial differential equations even in the case when equations do not have symmetry algebras sufficient for integration.

Abstract:
The article presents the results of a study on the dynamics of the semantic structure of the modern Russian media discourse key concepts: family, patriotism, and business. On the one hand, the relevance of the topic of the article is due to the huge influencing potential of the media texts. On the other hand, it is due to the design of the semantic-cognitive approach to media speech. The main task of the author is to identify the features of the modernization of the semantic structure of concepts with significant- content. To implement this task, a three-stage analytical algorithm was used, which involves the analysis of the lexicographic description of the concept word, identifying its real, the study of discursive interpretation in the media space is the identification of the value component of the semantic structure of the concept presented in journalistic lexical and phraseological stereotypes and to some extent original contexts that form an associative semantic field in which interrelated, mutually conditioned meanings and meanings are presented. The empirical basis of the research is more than 200 media texts of different genres published over two decades in Russian media of different types and different discursive affiliation. The author comes to the conclusion that modern media are actively working, first of all, on the modernization of the axiological (value) component of the semantic structure of mentally significant concepts. The techniques of transformation of conceptual associative-semantic fields are largely associated with the neutralization of conflicts caused by the general attitude of modern media systems to the formation of a consolidated picture of the world with an extremely minimized national component. The prospects for the development of this research topic are connected with the development of the axiology of journalism and with the formation of such a direction of media studies as media anthropology, with the development of new analytical methods corresponding to the long – standing idea of M. M. Bakhtin, who insists on the need to create national comparative studies – a scientific direction that combines the achievements of many humanitarian disciplines.

Abstract:
Abstract Almost all the media the particles move in are non-static, one of which is the most common expanding or contracting (by a scale factor) non-static medium discussed in this paper. Depending on the expected resolution of the studied dynamics and the amplitude of the displacement caused by the non-static media, sometimes the non-static behaviors of the media can not be ignored. In this paper, we build the model describing Lévy walks in one-dimension uniformly non-static media, where the physical and comoving coordinates are connected by scale factor. We derive the equation governing the probability density function of the position of the particles in comoving coordinate. Using the Hermite orthogonal polynomial expansions, some statistical properties are obtained, such as mean squared displacements (MSDs) in both coordinates and kurtosis. For some representative non-static media and Lévy walks, the asymptotic behaviors of MSDs in both coordinates are analyzed in detail. The stationary distributions and mean first passage time for some cases are also discussed through numerical simulations.
