It is contended that one of the promising directions for solving the problem of incommensurability of paradigms, coined by T. Kuhn and P. Feyerabend, can be associated with the trend of advancement of neo-Kantian epistemology, presented by the writings of Ernst Cassirer. According to Cassirer, the statements fixing connections and relationships between mathematical ideal constructs form a “neutral language” that can serve as a firm ground for comparing the “old” and “new” paradigms. A case study of the genesis and functioning of a neutral mathematical language related to the Maxwellian synthesis of optics and electromagnetism isprovided. It is elicited that its basis is constituted by the mathematical language of continuum mechanics. The main function of the neutral language was to project the consequences of all the unified theories onto the mathematical model, “rewrite” all known laws in this mathematical language, compare their conclusions with each other to eliminate contradictions and generalize the stuff in a self-consistent system of equations.

One of the priority directions of the state policy is the development of the sphere of physical culture and sports as a significant branch of national economy and socio-economic practice of effective management. In the current economic conditions, on the one hand, there are tendencies to increase commercialization in the sports industry. On the other hand, the need for financial support, diversification of sources and modernization of the sports financing model, increasing the effectiveness of public-private partnership mechanisms, and developing state order tools in order to achieve sustainable industry dynamics are announced. The severity and unresolved financial and economic problems of sports development determined the choice of the direction of this study and its relevance. In the process of research based on the synthesis of system and process approaches, we used methods of economic cybernetics, organization theory, construction of structural-information decision-making schemes using analytical assessments, tools of structural-logical and criteria analysis, methodological approaches of unit economics. As a result, the poly-subject environment of the industry ecosystem was determined, a conceptual approach to the formation of the financial model of sports was developed, the structural and functional space of the ecosystem business model was designed taking into account its digital component, sources, business processes and alternative financing objects were identified, a set of model parameters and infrastructure components were developed.

This work presents the first instance of a silica few-mode microstructured optical fiber (MOF) being successfully fabricated with a hollow GeO2-doped ring core and by strongly inducing twisting up to 790 revolutions per meter. Some technological issues that occurred during the manufacturing of the GeO2-doped supporting elements for the large hollow cores are also described, which complicated the spinning of the MOFs discussed above. We also provide the results of the tests performed for the pilot samples—designed and manufactured using the untwisted and twisted MOFs described above—which were characterized by an outer diameter of 65 µm, a hollow ring core with an inner diameter of 30.5 µm, under a wall thickness of 1.7 µm, and a refractive index difference of Δn = 0.030. Moreover, their geometrical parameters, basic transmission characteristics, and the measurements of the far-field laser beam profile patterns are also provided.

Bruno Latour’s distinctive historiographic standpoint on the origins of scientific revolutions and the multifarious accounts of their reconstructions are elicited. It is contended that, in spite of their highly iconoclastic character, Latour’s views can be welcomed for their innovative approach to the inquiries of social facets of science. In particular, they can elucidate the foundations of the lucid mature theory change model proffered in our preceding writings. Correspondingly, the Copernican Revolution is envisaged in the wayward context of intense interaction and interpenetration of Aristotelean and Ptolemaic sophisticated research practices. Eventually, the Aristotle – Ptolemy pagan cosmology could not help but be exposed to repeated cogent attacks during the Middle Ages since it apparently confronted the renowned principles of monotheism, not admitting the impervious demarcation line between the celestial and mundane realms. All the opposite worlds should have one and the same Creator. Commencing with the unification, Copernicus, in effect, paved the way for the descent of mathematics from Heaven to Earth and the spread of natural philosophy from Earth to Heaven.

Phenotypes of athletic performance and exercise capacity are complex traits influenced by both genetic and environmental factors. This update on the panel of genetic markers (DNA polymorphisms) associated with athlete status summarises recent advances in sports genomics research, including findings from candidate gene and genome-wide association (GWAS) studies, meta-analyses, and findings involving larger-scale initiatives such as the UK Biobank. As of the end of May 2023, a total of 251 DNA polymorphisms have been associated with athlete status, of which 128 genetic markers were positively associated with athlete status in at least two studies (41 endurance-related, 45 power-related, and 42 strength-related). The most promising genetic markers include the AMPD1 rs17602729 C, CDKN1A rs236448 A, HFE rs1799945 G, MYBPC3 rs1052373 G, NFIA-AS2 rs1572312 C, PPARA rs4253778 G, and PPARGC1A rs8192678 G alleles for endurance; ACTN3 rs1815739 C, AMPD1 rs17602729 C, CDKN1A rs236448 C, CPNE5 rs3213537 G, GALNTL6 rs558129 T, IGF2 rs680 G, IGSF3 rs699785 A, NOS3 rs2070744 T, and TRHR rs7832552 T alleles for power; and ACTN3 rs1815739 C, AR ≥21 CAG repeats, LRPPRC rs10186876 A, MMS22L rs9320823 T, PHACTR1 rs6905419 C, and PPARG rs1801282 G alleles for strength. It should be appreciated, however, that elite performance still cannot be predicted well using only genetic testing.

The aim of the research is to identify universal patterns and specific features in the semantic fields of phraseological units with the somatism “head” in the Canadian French, French and English languages. The scientific novelty of the research is accounted for by the fact that the relationship between culture and language and the issues associated with the reflection of the national-cultural distinctness of the functional and semantic features that are peculiar to phraseological units with the somatism “head” in Canadian French, French and English has been little studied. The paper carries out a comparative analysis of phraseological units with the somatism “head” in Canadian French, French and English, identifies and systematises the semantic values of these phraseological units, determines equivalents and lacunae in the semantic fields of these phraseological units in the languages compared. As a result, it has been proved that the somatism “head” is a part of a large number of phraseological units in the languages compared, however, there are more similarities in the semantics of these phraseological units in French and English, while Canadian French, due to the use of French set expressions and idioms, shows greater lacunarity.

The α-actinin-3 (ACTN3) gene rs1815739 (C/T, R577X) polymorphism is a variant frequently associated with athletic performance among different populations. However, there is limited research on the impact of this variant on athlete status and physical performance in basketball players. Therefore, the aim of this study was twofold: (1) to determine the association of ACTN3 rs1815739 polymorphism with changes in physical performance in response to six weeks of training in elite basketball players using 30 m sprint and Yo-Yo Intermittent Recovery Test Level 2 (IR 2) tests, and (2) to compare ACTN3 genotype and allelic frequencies between elite basketball players and controls. The study included a total of 363 individuals, comprising 101 elite basketball players and 262 sedentary individuals. Genomic DNA was isolated from oral epithelial cells or leukocytes, and genotyping was performed by real-time PCR using KASP genotyping method or by microarray analysis. We found that the frequency of the ACTN3 rs1815739 XX genotype was significantly lower in basketball players compared to controls (10.9 vs. 21.4%, p = 0.023), suggesting that RR/RX genotypes were more favorable for playing basketball. Statistically significant (p = 0.045) changes were observed in Yo-Yo IRT 2 performance measurement tests in basketball players with the RR genotype only. In conclusion, our findings suggest that the carriage of the ACTN3 rs1815739 R allele may confer an advantage in basketball.

Abstract Backgroundː The aim of this study was to compare changes in plantar pressure distribution during normal stance lunges and service by professional badminton players. Methodsː The study involved 12 badminton players. The Tekscan HR pedobarographic platform (USA) was used to record data. Resultsː The results showed that both the forefoot and the hindfoot were loaded differently depending on the stage of the delivery being performed or the posture adopted. In the area of the midfoot, metatarsals and toes of the left foot, the peak pressure was lower, and the highest value was in the 3rd metatarsal during a calm stance. An analysis of changes in pressure on the foot after loading, however, relative to the initial stance showed a trend in the distribution of load on the outer surface in the left foot. On the right foot, in contrast, toe use decreased by 50%, but heel support increased by 20%, and midfoot pressure increased by 20%. During the delivery in the swing phase, there was an increase in pressure in the area of the heel of the unsupported leg. In the lunge phase, the pressure was distributed over the entire plantar surface, however, the pressure distribution remained uneven with an area of greater pressure in the heel and lateral part of the metatarsus. Conclusionsː It is recommended to introduce exercises into the training process aimed at preventing and correcting the correct position of the feet in order to reduce the risk of injuries to the ankle and knee joints.
