Confining density functional approach for color superconducting quark matter and mesonic correlations

We present a novel relativistic density-functional approach to modeling quark matter with a mechanism to mimic confinement. The quasiparticle treatment of quarks provides their suppression due to large quark selfenergy already at the mean-field level. We demonstrate that our approach is equivalent to a chiral quark model with medium-dependent couplings. The dynamical restoration of the chiral symmetry is ensured by construction of the density functional. Beyond the mean field, quark correlations in the pseudoscalar channel are described within the Gaussian approximation. This explicitly introduces pionic states into the model. Their contribution to the thermodynamic potential is analyzed within the Beth–Uhlenbeck framework. The modification of the meson mass spectrum in the vicinity of thee (de)confinement transition is interpreted as the Mott transition. Supplemented with the vector repulsion and diquark pairing the model is applied to construct a hybrid quark-hadron EoS of cold compact-star matter. We study the connection of such a hybrid EoS with the stellar mass-radius relation and tidal deformability. The model results are compared to various observational constraints including the NICER radius measurement of PSR J0740+6620 and the tidal deformability constraint from GW170817. The model is shown to be consistent with the constraints, still allowing for further improvement by adjusting the vector repulsion and diquark pairing couplings.

Electron Delocalization on the Silicon Nanoparticles Surface

The specific properties of tubular and fullerenlike silicon nanoparticles depend on theirs electronic structure, which is directly related to the surface geometry. Using density functional approach, a novel dual nature of the surface structure of silicon nanotubes which depends on the type of nanotube have been revevaled. The rippled form of the surface has shown to be a favorable one for (n, n) type structure and the most stable form for (n, 0) Si NT is the nanotube with a smooth-walled graphene-like surface. The phenomenon is explained by the relative position of the non-hybridized p orbitals on the surface.

Cooperation and Environmental Responsibility as Positive Factors for Entrepreneurial Resilience

In this review, we study the state of entrepreneurial education as it applies to business resilience. We consider records over the last 20 years about entrepreneurial resilience that consider their social impact and focus on sustainability. The aim of the study was to determine whether an enterprise that stresses social impact and sustainability rather than profits could reinforce entrepreneurial resilience. The importance of this study is that it offers a more complex description of entrepreneurial resilience by connecting social and environmental sensitivity with a profit-oriented logic. We found a mild incremental rise in, first, the years of the 2000s and a jump by 2010. We then used VosViewer to create a cluster map from the record list of WOS, creating three clusters of: “education and sustainability”, “entrepreneurship and social impact” and “innovation”, and these three clusters were related to superior entrepreneurial resilience. This approach should be adopted in real time to be able to adapt to socio-economic crises, adopting a functional approach based on cooperativeness and awareness of complexity.

Using the Phonological Approach to Describe the Vocal System of the Russian Language in the Context of Russian-Spanish Language Contact

The article is devoted to the description of the vocal systems of different languages, considering the functional approach, based on the objective linguistic reality. Today the traditional approach used by research scientists is gradually losing the ability to identify effective models of the phonetic-phonological system of the language, which significantly affects the productivity and research results. The rapid development of new directions of science, the evolution of the language system and all its sublevels indicates the need to adjust the traditional principles of describing phonetic-phonological systems of different languages and imposes special requirements on the relevance, productivity, adequacy and compliance of such descriptions with objective reality. The article analyzes the system of vowels from a phonological point of view - a general classification of vowels through the prism of phonological systematics of meaningful oppositions - considering the articulatory base of the language and the modern orthoepic norm, their changes in the flow of speech, an inextricable connection with consonantism and the prosodic organization of the word. This system is more productive and relevant for solving the problems of modern linguistics. The approbation of the vocal system of the Russian language, obtained within the framework of the corrected approach to the description of systems, is carried out in conditions of language contact, since the problems of language contact are interconnected with the main tasks of the theory of language in the framework of the comparative historical description and comparison of languages. Phonetic interference, together with a foreign accent, is a consequence of the contact between the native language and the target language. Phonetic interference, being an integral part of linguistic contact, causes a violation of the sound side of the language of foreigners. After analyzing the descriptions of the vocal systems of the Spanish and Russian languages, made within the framework of the adjusted functional approach, it is possible to highlight the main features of the Spanish accent in the pronunciation of Russian vowel sounds, and the analysis of the practical material confirms all the selected features and demonstrates the high efficiency of the above approach. The results of this work can be used in various theoretical courses, as well as to create systems for automatic synthesis and speech recognition.

Metoda unilateralna w prawie prywatnym międzynarodowym. Uwagi na marginesie orzeczenia TSUE w sprawie C-135/15 Republika Grecji przeciwko Grigoriosowi Nikiforidisowi

The article confronts the unilateral and multilateral methods in private international law. The author first identifies the basic differences between the two. She then moves to describe the instruments and concepts resulting from the unilateral method: the theories of the Statutists in the period between 12th to 19th centuries, the solutions offered by the so called new American school, the method of recognition of private situations crystallized in a foreign legal system, the rules governing the spatial scope of the EU provisions, including the regulations and the directives, and finally the paradigm of the overriding mandatory rules. The second part of the paper provides a comment to the Nikiforidis case. The author makes a number of critical remarks with respect to the restrictive and rigid interpretation of Article 9(3) adopted by the CJEU. The argument is made that the more flexible and functional approach proposed by the Attorney General Maciej Szpunar in his Opinion should be preferred. Finally, the author makes her own proposition regarding the Nikiforidis case. She advocates a unilateral methodology that rejects the distinction between the overriding mandatory rules of the legis fori, legis causae and these of a third country.

Dydaktyka polonistyczna online w czasach kwarantanny

In the paper I discuss the most important trends observed in teaching the Polish language in online TV lessons during the quarantine period. Polish lessons during the Covid-19 pandemic are an important source of knowledge about methodological and didactic trends in Polish schools. They enable the study of contemporary educational habits, as well as ways of their mediatization. Remote education engages teachers and students differently than classroom lessons. I am askingif it creates new didactic perspectives or if it turns out to be just a prosthesis of a traditionally functioning school. I make an analytical review of online Polish language lessons for secondary schools of April, May and June 2020. I note that during the pandemic, an attractive and functional approach to distance learning was not developed, but one methodological tendency was highlighted, namely presentismand providing information.
