Effect of intermediate Minkowskian evolution on CMB bispectrum

We consider a non-inflationary early Universe scenario in which relevant scalar perturbations get frozen out at some point, but then are defrosted and follow a long nearly Minkowskian evolution before the hot era. This intermediate stage leaves specific imprint on the CMB 3-point function, largely independent of details of microscopic physics. In particular, the CMB bispectrum undergoes oscillations in the multipole l space with roughly constant amplitude. The latter is in contrast to the oscillatory bispectrum enhanced in the flattened triangle limit, as predicted by inflation with non-Bunch--Davies vacuum. Given this and other peculiar features of the bispectrum, stringent constraints imposed by the Planck data may not apply. The CMB 3-point function is suppressed by the inverse duration squared of the Minkowskian evolution, but can be of observable size for relatively short intermediate Minkowskian stage.Comment: 27 pages, 5 figures; references added, representation of the material improved; matches journal versio

Development of electronic communications in the financial market-based system

Purpose: The article aims at revealing opportunities for forming long-term effective partnership communication with the consumer in the financial market. It elicits prospects for the development of communications in the financial market, considers reactions as responsive behavioral switching nodes evolving in the course of interaction and defines opportunities for forming long-term effective partnerships with consumers. Design / Methodology / Approach: To provide information for marketing communications in the financial market and ensure security, it is necessary: first, to study possible risks of communication and problems which are likely to happen in the course and as a result of interaction and counteraction to hostile manipulations in the information network; second, to provide protection of consumers and target groups' rights and cooperation with public authorities in the field of information and communication security; third, to monitor staff activities; fourth, to entail market research and analysis of new segments, market stakeholders of traditional and innovative services. Findings: To enhance effectiveness of electronic communications in the financial market-based system, a set of measures for information support of marketing communications in the financial market has been elaborated to further ensure security. The technique of modern PR-communications in business is a universal tool of marketing technologies designed to create favorable public opinion and a positive perception of a certain economic entity. At the same time, maximum coverage implies forecasting the future development of the market situation in the financial market and establishing contact with the interested audience. Practical implications: The results of the study can be introduced into management practice to adapt the existing system of banking products distribution to innovative market demands and indicators of hidden and unmet demand and to develop and ideally implement innovative banking services. Originality/Value: The major contribution of this research is to identify prospects for communications development in the financial market and form reactions as response behavioral switching nodes arising in the course of interaction.peer-reviewe
