In this paper, we make a phenomenological study of the mass–radii relationship of hybrid stars from the point of view of the smooth crossover phase transition. We find a way to construct stiff hybrid equations of state (EOSs) with soft EOSs of both the quark matter and the hadronic matter. For the hadron phase, we adopt the EOS softened by introducing hyperons that are considered to exist in the core of a neutron star. For the quark phase, we introduce a quark EOS based on the Dyson–Schwinger equation (DSE) that is calculated in our previous work, and it is also a soft EOS. In contrast to the hybrid EOS based on Maxwell condition, we find that the resulting EOS is stiff and the maximum mass of the hybrid stars is still about two times of solar mass. This result indicates the rich possibilities of the crossover model.

AbstractNonperturbative equations of state (EoSs) for two and three quark flavors are constructed with the functional renormalization group (FRG) within a quark-meson model truncation augmented by vector mesons for low temperature and high density. Based on previous FRG studies without repulsive vector meson interactions the influence of isoscalar vector ω- and ϕ-mesons on the dynamical fluctuations of quarks and (pseudo)scalar mesons is investigated. The grand potential as well as vector meson condensates are evaluated as a function of quark chemical potential and the quark matter EoS in β-equilibrium is applied to neutron star (NS) physics. The tidal deformability and mass-radius relations for hybrid stars from combined hadronic and quark matter EoSs are compared for different vector couplings. We observe a significant impact of the vector mesons on the quark matter EoS such that the resulting EoS is sufficiently stiff to support two-solar-mass neutron stars.

This article studies the cognitive features of the “power” frame and its gender implementation in the historical tragedy by W. Shakespeare “Macbeth”. Here, the author examines the concepts of “frame” and “gender” in linguistics, studying different approaches to their definition. The relevance of this work is determined by the close attention of the contemporary linguistics to these concepts, as well as their place in the contemporary academic paradigm. The academic affirmation of the “frame” and “gender” concepts designates a new step in understanding the ways and peculiarities of the language interaction, consciousness, and culture, and, consequently, it shows new aspects of the relationship of linguistics with other sciences. Nevertheless, the problems of both frame and gender are not yet fully understood. This study allows describing in detail the essence of the frame “power” and showing its meaning, use, and ways of its gender implementation in fiction, which explains the novelty of this article. The study’s methodology is based on the cognitive-discursive analysis of the text, as well as on an integrative approach to the discourse study, which combines methods of both cognitive and gender linguistics, as well as the discourse analysis. Common research methods were used along with private linguistic methods. The application of cognitive-discursive analysis has significantly increased the depth of understanding of the “power” frame that dominates Shakespeare’s historical tragedy. This historical text presents the central theme of political tragedy: the overthrow of the rightful ruler and the usurpation of power. The motive for the seizure of power forms a thematic core and is presented from the usurpers’ point of view. In this article, the author observes the gender shift and duality of the female and male beginnings: Shakespeare puts the female protagonist, hungry for power, among men, thus the images of Lady Macbeth and her husband come into conflict with the gender characteristics attributed to them. The play clearly traces the main idea of Machiavellianism: the goal justifies the means. The results conclude that the “power” frame is the leading one in Lady Macbeth’s monologue, thus setting one of the main themes of this tragedy.

Задачей данной статьи является рассмотрение лингвопрагматических особенностей комментариев пользователей социальной сети «Твиттер» на выход Великобритании из ЕС. Анализ данных комментариев с лингвопрагматической точки зрения представляет интерес, так как показывает наиболее актуальную картину отношения пользователей социальных сетей к произошедшему событию. Приоритетными методами анализа лингвопрагматического потенциала Интернет-комментариев для нас являются: описательный метод, метод прагматического анализа, т.е. рассмотрение языкового материала в его непосредственном контексте в функциональном аспекте, метод частичной выборки, метод контекстологического описания. Контекстуальный метод был использован с целью установления особенностей комментариев в среде социальной сети «Твиттер»; описательный метод - для выявления непосредственного отношения пользователей социальных сетей к выходу Великобритании из ЕС; частичной выборки - для отбора наиболее эффективных и целостных комментариев с позиции прагматики и их реализации в данном контексте. Проведённое исследование позволило установить, что большинство людей удовлетворено результатами выхода Великобритании из ЕС и положительно отзывается об этом событии. Об этом свидетельствует как большое количество экспрессивов, использованных в интернет-комментариях в отношении данного события, так и активное употребление в них оценочной лексики. Результаты проведённого исследования могут быть применены в теоретических работах по описанию характеристик речевых актов, в курсе теоретической грамматики, стилистики, прагмалингвистики. The purpose of this article is to review the linguo-pragmatic features of Brexit represented in the comments in Twitter. Their analysis from a linguistic-pragmatic point of view may be of interest, since it shows the most relevant picture of the relationship of social network users for the event. The priority methods for analyzing the linguo-pragmatic potential of Internet comments for us are: a descriptive method, a pragmatic analysis method, i.e. consideration of linguistic material in its immediate context in the functional aspect, partial sampling method, contextual description method. The contextual method was used to establish the characteristics of comments on the Twitter social network; descriptive method was used to identify the direct relationship of social network users to the UK exit from the EU; partial sampling was used to select the most effective and holistic comments from the position of pragmatics and their implementation in this context. The study found that most people are satisfied with the results of the UK exit from the EU and respond positively to this event. The results of the study can be applied in theoretical works on the description of the characteristics of speech acts, in the course of theoretical grammar, stylistics, pragmalinguistics.

We analyse the hadron/quark phase transition described by the Nambu-Jona-Lasinio (NJL) model [quark phase] and the extended Nambu-Jona-Lasinio model (eNJL) [hadron phase]. While the original formulation of the NJL model is not capable of describing hadronic properties due to its lack of confinement, it can be extended with a scalar-vector interaction so it exhibits this property, the so-called eNJL model. As part of this analysis, we obtain the equations of state within the SU(2) versions of both models for the hadron and the quark phases and determine the binodal surface.

Abstract. The aim of this work is to investigate the relationship between indicators of cicatricial digestion and linearity of cows. Methods. The research was carried out in the breeding enterprises of the Sverdlovsk region on the livestock of Ural-type cows. Cicatricial fluid was collected with an oropharyngeal rubber probe, and a wooden yaw was also used. Cicatricial content was assessed at the Chelyabinsk Interregional Veterinary Laboratory. The pH value was determined by the electrometric method, VFA – in the Markgam apparatus, ammonia – by the microdiffusion method. Ciliates – in Goryaev’s chamber and under a microscope, bacteria – under a microscope with the addition of sodium chloride solution. Statistical data processing was carried out in the Microsoft Office Excel 2010 program. Results. In terms of the number of ciliates and bacteria in the rumen fluid, the Montwick Chieftain cows, characterized by high productive qualities, had an advantage. In terms of pH and VFA, the Vis Back Ideal line was the best. There were no significant differences between the groups in terms of the amount of ammonia in the rumen. The best animals from the point of view of influence on cicatricial metabolism were the animals of the Vis Back Ideal and Montwick Chieftain lineage. Scientific novelty. Studies have shown that linearity is associated with cicatricial digestion in cows. The relationship of bull lines with indicators of cicatricial metabolism of cows has been determined for the first time. The food in the rumen is digested due to the action of bacteria, ciliates, and fungi. An environment has been created in the rumen for the active development of microflora. Bacteria are able to synthesize amino acids and vitamins. The proventriculus can contain up to 50 species of ciliates.

Introduction. The article compares the methods of researching political discourse with special attention to linguistic methods, in particular, to discourse analysis and cognitive and rhetorical approaches. These methods are widely used to study political speeches, statements, texts. Increasingly, political discourse is seen as a social phenomenon, not only at the discursive but also on the cognitive and rhetorical levels. The object of this study is methods of analysis of political discourse allowing to study the position of a politician in the discursive sphere and to identify the character of his audience. The subject of the analysis are examples from Joe Biden's political speeches, seen as an instrument of influence, persuasion in the process of speaking to the electorate. The relevance of the work is determined by the need to develop arguments to choose a particular approach to political discourse, especially cognitive and rhetorical, as well as discourse analysis, which allow to reveal veiled meanings of political statements and consider the methods of persuasion of the electorate.Methodology and data sources. The subject of the analysis are examples of Joe Biden’s political speeches, seen as an instrument of influence, persuasion in the process of speaking to the electorate. To compare approaches the study of political discourse, descriptive and comparative methods are used, the effectiveness of different approaches and methods is illustrated by specific examples of linguistic interpretation of discursive features of publications and speeches, revealing the ambitions of the politician most fully. A method of quantitative counting is also used.Results and discussion. The use of descriptive and comparative methods makes it possible to compare different approaches to the study of political texts and speeches, to discuss the relationship of heterogeneous methods, to identify the most effective methods of studying discourse. The result of the article was the conclusions about the effectiveness of different approaches to the study of the language of politicians at discursive, cognitive and rhetorical levels. Comparison of methods of research of political discourse distinguishes discourse-analysis among other methods of analysis. The use of discourse analysis to study political discourse reveals the functions of discourse, for example, manipulative, selective and combined functions related to political goals. The use of critical discourse analysis allows you to identify these functions most fully.Conclusion. The study of political discourse can be carried out at different levels, but the discursive level compared to cognitive and rhetorical levels is the most effective from a linguistic point of view. Discourse analysis allows to explore political discourse at more qualitative different level than rhetorical and other linguistic methods of research. Discourse analysis is presented as a method of researching hidden meanings in politics in this article.

This article examines the problem of overcoming nihilism in Heidegger’s dialogue with Jünger. It is suggested that nihilism is manifested in various forms and is the deep logic of the whole history of European civilization. One of the main aims of this paper is to outline the relationship of nihilism and Nothing in Heidegger’s dispute with Jünger, viewing how Heidegger distinguishes his approach from Jünger’s point of view. Heidegger, on the one hand, treats nihilism as consummation of the Western metaphysical tradition, on the other hand, identifies Nothing itself as the shadow of Being, which cannot be overcome in the traditional dialectical thinking manner.

RESUMO Ao observar as relações de Nietzsche com seus contemporâneos verifica-se que ele estava ciente das principais discussões relativas à Unificação da Alemanha (1871). Para a unificação era necessário que os 39 estados alemães compartilhassem o sentimento de pertencimento a uma pátria comum. Nesse meandro, os historiadores prussianos do século XIX desempenharam papel fundamental ao produzir um ambiente filosófico nacionalista, uma maneira científica e objetiva de pensar sobre a história. O objetivo deste trabalho é compreender as interações de Nietzsche com estes círculos intelectuais. Para isto, foram selecionados quatro dos chamados fragmentos póstumos de Nietzsche datados entre 1871 e 1873. De acordo com o ponto de vista de Nietzsche, as pretensões dos historiadores, não tinham nenhuma crítica, pois acreditavam, ingenuamente, que a verdade era um alvo tangível. Por outro lado, ele indicou a necessidade de uma história ligada à cultura, que era trabalhada em conjunto com "instintos artísticos".  ABSTRACT By observing the relationship of Nietzsche with his contemporaries one can notice that he was aware of the main discussions related to the unification of Germany (1871). Unification required 39 German states to share the feeling of belonging to a common homeland. Prussian historians of the nineteenth century played a key role in producing such a nationalist philosophical environment, a scientific and objectivist way of thinking about History. This work aim is to understand the interactions between Nietzsche and this intelectual circles. For this purpose, four of the so-called posthumous Nietzsche fragments, dated between 1871 and 1873, were selected. According to Nietzsche's point of view, some historians had a naive pretension to reach the truth, as if it were a tangible target. On another hand, he pointed out the necessity of a link between History and Culture, which should be understood altogether with ‘artistic instincts’.

Frequent public uproar over forms of data science that rely on information about people demonstrates the challenges of defining and demonstrating trustworthy digital data research practices. This paper reviews problems of trustworthiness in what we term pervasive data research: scholarship that relies on the rich information generated about people through digital interaction. We highlight the entwined problems of participant unawareness of such research and the relationship of pervasive data research to corporate datafication and surveillance. We suggest a way forward by drawing from the history of a different methodological approach in which researchers have struggled with trustworthy practice: ethnography. To grapple with the colonial legacy of their methods, ethnographers have developed analytic lenses and researcher practices that foreground relations of awareness and power. These lenses are inspiring but also challenging for pervasive data research, given the flattening of contexts inherent in digital data collection. We propose ways that pervasive data researchers can incorporate reflection on awareness and power within their research to support the development of trustworthy data science.
