We define the notion of an $S^1$-bundle of projective special complex base type and construct a conical special complex manifold from it. Consequently the base space of such an $S^{1}$-bundle can be realized as $\mathbb{C}^{\ast}$-quotient of a conical special complex manifold. As a corollary, we give an intrinsic characterization of a projective special complex manifold generalizing Mantegazza's characterization of a projective special Kähler manifold. Our characterization is in the language of c-projective structures. As an application, a non-trivial $S^1$-family of Obata-Ricci-flat hypercomplex structures (given by a generalization of the rigid c-map) on the tangent bundle of the total space of a $\mathbb{C}^*$-bundle over a complex manifold with certain kind of c-projective structure is constructed. Finally, we show that the quaternionic structure underlying any of these hypercomplex structures is in general not flat and that its flatness implies the vanishing of the c-projective Weyl tensor of the base of the $\mathbb{C}^*$-bundle. Conversely, any c-projectively flat complex manifold satisfying a cohomological integrality condition gives rise to a flat quaternionic structure.

Abstract Background Telocytes (TCs) are small interstitial cells that extend into multiple bead-like protrusions called telopodes (TPs). TCs are widely found in many tissues and organs, form connections with almost all types of cardiomyocytes, and participate in regulating cardiac microenvironment homeostasis. Methods In this study, transmission electron microscopy combined with special staining techniques (Gomori’s, Masson’s trichrome, and toluidine blue staining) were used to analyse the ultrastructure, distribution, and cytochemical characteristics of TCs in yak hearts. Immunohistochemistry and immunofluorescence double staining techniques were combined to identify the immunophenotypic characteristics of TCs functional markers (CD34, CD117, PDGFR-α and α-SMA) and further reveal their potential functions. Results The results showed that the TCs in the aortic bulb of yak hearts had prominent nuclei, and thin, long TPs with abundant secretory vesicles. TCs in the myocardial tissue exhibited irregularly shaped nuclei, shorter TPs, and connections with myocardial fibres and adjacent capillaries, forming a complex TC network. Immunohistochemical results demonstrated the positive expression of functional markers CD34, CD117, α-SMA and PDGFR-α in both the aortic bulb and myocardium. Immunofluorescence double staining results indicated co-expression of CD34/CD117, CD34/α-SMA, and CD117/PDGFR-α in TCs. Conclusion This is the first study to report the presence of TCs in the aortic bulb and myocardium of yak hearts and that it may form TC networks that mainly participate in mechanical support and cell communication in the heart. The presence and distribution characteristics of TCs in the heart of yaks provide important clues for further research on the role of TC networks in the adaptability of plateau animals to the environment.

IntroductionPhonological processes lie at the intersection of phonetics and morphology. These processes examine various speech and written forms related to morphemes, aiming to investigate how certain words or morphemes are realized phonologically in different lexical or grammatical contexts. The present research aimed to investigate the phonological realization process in Zanjani Turkish based on Optimality Theory (Prince & Smolensky, 1993).The main goal of the Optimality Theory in phonology is to determine how phonological patterns of languages can be explained using constraints. Two types of constraints are examined in this theory: Markedness Constraint and Faithfulness Constraint. Optimality Theory is a method of interpreting constraints, which can be used as a tool in linguistic theories. The core logic of Optimality is based on the premise that constraints cannot be interpreted as binary (satisfied or violated), but rather they are ranked based on their relationship to each other. Such a hierarchical structure results in lower-ranked constraints being violated in favor of higher-ranked constraints.Optimality Theory relies on a conceptually simple but surprisingly rich notion of constraint interaction, where the satisfaction of one constraint can be designated to take absolute priority over the satisfaction of another. The means that grammar uses to resolve conflicts is to rank constraints in a strict dominance hierarchy. Each constraint has absolute priority over all the constraints lower in the hierarchy (Prince & Smolensky, 1993: 2).In Optimality Theory, there are two basic types of constraints. Faithfulness constraints require that the observed surface form (the output) match the underlying or lexical form (the input) in some particular way; that is, these constraints require identity between input and output forms. Markedness constraints, on the other hand, impose requirements on the structural well-formedness of the output. Both types of constraints play a crucial role in the theory, working together to yield the optimal candidate.Optimality Theory also utilizes a Generator (GEN) which generates a list of outputs or candidates from a given input (McCarthy, 2008, p.16).GEN (Input) = {Cand1, Cand2, …}The Generator function has the freedom of analysis so that it can generate unlimited phonetic forms for each word. (McCarthy, 2002, p. 8). The optimal candidate is then chosen by the Evaluator (EVAL) based on the language specific constraints. (McCarthy, 2008: 19): Generator Evaluator Input → → Candidates → → Output Optimal Theory Model (McCarthy, 2002: 10) In order to show the function of GEN and EVAL, Optimality Theory utilizes the tables labeled as tableau. On the other hand, morpho-phonology is the branch of linguistics that studies the interaction between morphological and phonological processes. Morpho-phonological analysis often involves formulating a set of formal rules or constraints that successfully predict regular sound changes occurring in the morphemes of a given language. When morphemes combine, they influence each other’s sound structure, resulting in different variant pronunciations of the same morpheme. This study sought to answer how phonological processes in Zanjani Turkish can be described based on Optimality Theory and how constraints are ranked in these processes. It is evident that Optimality Theory in phonology does not face the limitations of previous generative approaches and is capable of describing all phonological processes across languages, including Zanjani Turkish. Additionally, language forms a part of the cultural identity of each community, and studying the language of a community holds special significance for understanding that community. Considering that a considerable portion of Iran's population speaks Azerbaijani Turkishm and the Zanjani dialect is part of it, studying it is a necessary step toward preserving our country's cultural and linguistic heritage. This research was limited to the city of Zanjan. The researchers are natives of Zanjan and speak Zanjani Turkish. Materials and MethodsData for this study were collected using the interview method, which is one of the fundamental, and perhaps the best, methods of gathering information, especially in dialect studies. Both fieldwork and library methods were employed. The library method was primarily used to collect background theoretical and descriptive studies. Data collection was carried out by approaching native Zanjani dialect speakers, both men and women. Speakers were selected from three age groups, ranging from 15 to 70 years old: adolescents (10 individuals), middle-aged adults (10 individuals), and older adults (10 individuals). The interviews were conducted in a friendly environment to minimize the influence of hypercorrection. All phonetic transcriptions in this research were prepared using the International Phonetic Alphabet (IPA), 2005 version. In this study, morpho-phonetic processed are defined as phonetic changes that occur in the morphemic context, i.e., at the boundary between morphemes, and have phonetic motivation. This research was conducted using descriptive and analytical methods, based on data gathered from native speakers of Zanjani Turkish through a structured questionnaire. The morpho-phonological processes in Zanjani Turkish were analyzed within the framework of Optimality Theory. Results and DiscussionThe data indicate that the high-ranking constraint ONSET (which requires syllables to begin with a consonant) and the HARMONY constraint (which requires the vowel in a suffix to harmonize with the back/front and round/non-round features of the final vowel in the root) play a crucial role in the morpho-phonology of the Zanjani dialect. Violating these constraints significantly reduces optimality. As observed, the plural suffixes (lɑr and lær), ablative suffixes (dæn and dɑn), indirect object suffixes (ɑ and æ), dative (dæ and dɑ), and conditional suffixes (sæ and sɑ) harmonize only with the back/front feature of the final vowel in the root. The accusative suffix (I), negation suffix (sIz), and subjunctive suffix (In) both harmonize with the back/front and the round/non-round features with the final vowel in the preceding root. The data also show that the DEP-IO constraint (do not insert a segment) holds a low rank in the ranking of constraints, as segment insertion or deletion sometimes occurs to avoid vowel hiatus. On the other hand, the MAXMS constraint (do not delete a mon-vocalic suffix) is given a high rank, and deviating from it is considered a violation. The findings of this research support earlier research by Sohrabi (2013), Razinezhad (2012), Razinezhad (2019), Mahmoudi Kojabad (2012), Mahmoudi and Modarresi-Qavami (2007), and Rezvani (2007), confirming that Azerbaijani Turkish is highly sensitive to vowel harmony. ConclusionsThe faithful constraints IDENT-IO (which requires that an output segment retain the same value as its corresponding input segment) is ranked low in the hierarchy of constraints. Violating this constraint does not render the option non-optimal. Sometimes, morpho-phonological processes lead to the phenomenon of homophony.Zanjani speakers, especially adults, sometimes adhere to complete assimilation. This suggests that the AGREE (feature) constraint is also ranked high. In conclusion, in morpho-phonological processes, two constraints HARMONY and IDENT-IO are always in competition. The HARMONY constraint holds a high rank, while the IDENT-IO constraint holds a low rank, meaning that its violating is not fatal. Another competition that arises during the process of assimilation is the competition between the high-ranking AGREE (feature) constraint (which requires the first vowel of a suffix to harmonize with the final vowel of the root) and the low-ranked IDENT-IO (feature) constraint (which requires the output segment to match the input).

The extended professional procedure (EPP) is carried out at primary schools as a special form of preventive work with children who manifest problems in their behavior and their primary environment. This paper aimed to investigate the experiences of experts — educators with backgrounds in social work, social pedagogy, or psychology, involved in the implementation of the EPP. We considered three research questions to investigate: (1) behavioral problems of children who participate in the EPP, (2) educators’ experiences with the implementation of the EPP, and (3) educators’ ideas for improving the program. For data collection, a qualitative focus group method was used, which included experts who have implemented the EPP; for data analysis, thematic qualitative analysis was used. The results show that children who were included in the EPP often manifested milder types of risky behaviors and usually came from families burdened with difficulties, a known risk factor for behavioral problems. Experiences of educators with the implementation of the EPP were both positive and negative. The negative aspects were mainly related to cooperation with the pedagogical service, social work institute, and parents, while the positive aspects were mainly related to the children’s perception of the program and the experts. The experts’ proposals and recommendations included improving the program by developing a clear definition of the EPP in both theory and practice, then paying strict attention to that definition.

In this paper we address the question of non-vanishing of $L'(0,f)$ where $f$ is an algebraic valued periodic function. In 2011, Gun, Murty and Rath studied the nature of special values of the derivatives of even Dirichlet-type functions and proved that it can be either zero or transcendental. Here for some special cases we characterize the set of functions for which $L'(0,f)$ is zero or transcendental. Using a theorem of Ramachandra about multiplicative independence of cyclotomic units we also provide some non-trivial examples of functions where $L'(0,f)$ is zero. Finally, assuming Schanuel's conjecture we derive the algebraic independence of special values of derivatives of $L$-functions.

To date, the knowledge of benthic macroinvertebrates in the upper reaches of the Jinsha River remains quite limited compared to other rivers in China due to the difficulty of sampling and special geographical environment. In this study, benthic macroinvertebrates in the upper reaches of the Jinsha River were investigated to address the knowledge gap. The results showed that dipterans dominated the communities, followed by amphipods and EPT taxa. The density, biomass and biodiversity were at a low level. As a high sediment-loaded river, unlike the Yellow River and the Wei River, oligochaetes are not commonly found in the upper reaches of the Jinsha River, and no mollusks were collected. The results of db-RDA showed that some natural factors influenced the spatial distribution of benthic macroinvertebrates in both dry and wet seasons, but during the flood season (summer and autumn), nitrogen and phosphorus became important factors due to severe soil erosion and high sediment loads in the water. The sections between above Batang and below Batang have obviously different substrates, resulting in the significantly different species composition and functional feeding groups. Moreover, higher habitat diversity can lead to higher benthic macroinvertebrate diversity after comparing the substrate types of the two sections. We consider that the unstable habitat conditions in the upper reaches of the Jinsha River are not conducive to completing the entire life cycle of benthic macroinvertebrates within a localized small habitat, and the communities are likely influenced more by seasonal contributions from populations in tributaries. Considering the impact of the existing cascade hydropower stations in the middle and lower reaches, and the realistic and potential impacts expected from the planned cascade hydropower stations in the upper reaches, it is imperative to prioritize the conservation of the tributaries along both banks of the upper Jinsha River. This enhanced conservation effort aims to preserve the diversity and integrity of benthic macroinvertebrates, which is of great significance in providing reliable food sources for the rare cold-water fish species and ensuring the safety of the aquatic ecosystem in the region.

The article describes the main forms of credit derivatives, the evolution of their development and conditions of use. Particular attention is paid to the conditions of protection against credit risk. The authors demonstrate the possibility and expediency of using credit derivatives in the financial practice of Ukrainian companies in the context of transformation of the current legislation. It is established that credit notes, as a form of credit derivatives, are a more reliable financial instrument. From an economic point of view, they are considered to be securities with a certain set of risks and benefits for investors, which should be taken into account when developing a financial strategy for all capital market participants. The subject of the study is the intricacies of using credit derivatives in financial management, with a special emphasis on their role and conditions in modern Ukrainian financial practice. The research methodology includes a critical review of the existing literature combined with an analysis of the current use of credit derivatives in Ukraine. This approach offers a dual perspective that not only summarises the global context but also takes into account the nuances of local implementation. The purpose of this study is to investigate the effectiveness of credit derivatives as financial instruments for risk hedging and profitability optimisation. By examining different types of these instruments, the study aims to draw practical conclusions and provide recommendations for integrating these instruments into financial management practices in Ukraine. The research concludes that credit derivatives offer significant advantages as reliable financial instruments that contribute to risk management and economic development. The paper highlights their potential to positively impact financial market development, especially under conditions that facilitate risk hedging. The findings of the publication support the creation of a specific legislative and regulatory framework that would facilitate the wider introduction and efficient use of credit derivatives in Ukraine. This includes emphasising the need for specific amendments to existing tax codes and financial regulations to create a favourable environment for these instruments.

The 21st century witnesses a significant surge in the role of a specific communication environment within a special network community. This phenomenon has catalysed the emergence of a new paradigm in educational activity, particularly in the realm of foreign languages. This paradigm, characterized by network learning and self-learning, is founded upon the principles of mass cooperation, the ideology of educational resource openness, and the networked organization of participants’ interaction. This article explores the possibilities and peculiarities of utilizing network technologies in students’ self-directed foreign language learning. Through network interaction, students can vastly expand the scope of linguistic self-education by leveraging social network cooperation, polymodal interaction, and the creation of virtual foreign language communicative environments. Central to this discussion are the main characteristics of networked educational interaction, which play pivotal roles in fostering individual subjectivity development. It is argued that network interaction affords students the opportunity to access a diverse range of conditions for shaping their individual trajectories of linguistic self-education. Moreover, foreign language instruction should encompass not only imparting knowledge and skills for information activities but also cultivating a culture of communication within the digital environment and fostering virtual intercultural competence. In conclusion, harnessing the vast potential of network technologies in foreign language self-learning facilitates language proficiency enhancement and effective development of skills across all types of language activities. Future research should focus on identifying pedagogical conditions conducive to cultivating students’ abilities in creating personalized linguistic self-educational environments

In this scientific article, the author analyzes the features of the application of a flexible working time regime in comparison with other types of special working time regimes, in particular irregular working hours, the shift method of work organization, as well as shift work. It was established that these special regimes have both common and distinctive features. Thus, the author stated that flexible working hours and irregular working hours have in common that: they are established exclusively on a contractual basis; are not implemented where their application is objectively impossible; the employee is not paid extra for the performance of a labor function beyond the normal duration of the working day. The differences are that: an employee with an irregular working day does not have the opportunity to self-regulate working hours, additional social guarantees are provided for an irregular working day. Common to shift and flexible regimes is that: employees are provided with equal guarantees regarding annual leave; the implementation of the specified regimes requires a bilateral will. What is special is that: the shift method directly assumes the place where the employee performs his work function; the shift method is applied exclusively to the enterprise, institution and organization as a whole, or individual divisions, and not to specific employees. From the analysis of flexible working hours and shift work, the author states that the common feature is that the use of the latter does not impose on the employee the obligation to actually work a greater number of hours; special guarantees of social and economic protection do not apply to employees. The difference comes down to the fact that: under a variable working time regime, the employee is obliged to perform a work function in a certain specified place; under variable working hours, the employee is obliged to perform the work function also at night, and under flexible working hours, the employee does not have this obligation.

Open quantum systems are a subject of immense interest as their understanding is crucial in the implementation of modern quantum technologies. In the study of their dynamics, the role of the initial system-environment correlations is commonly ignored. In this work, to gain insights into the role of these correlations, we solve an exactly solvable model of a single two-level system interacting with a spin environment, with the initial system state prepared by a suitable unitary operation. By solving the dynamics exactly for arbitrary system-environment coupling strength while taking into account the initial system-environment correlations, we show that the effect of the initial correlations is, in general, very significant and non-trivial. To further highlight the importance of the initial system-environment correlations, we also extend our study to investigate the dynamics of the entanglement between two two-level systems interacting with a common spin environment.

Let $B/F$ be a quaternion algebra over a totally real number field. We give an explicit formula for heights of special points on the quaternionic Shimura variety associated with $B$ in terms of Faltings heights of CM abelian varieties. Special points correspond to CM fields $E$ and partial CM-types $φ\subset \mathrm{Hom}(E, \mathbb{C})$. We then show that our height is compatible with the canonical height of a partial CM-type defined by Pila, Shankar, and Tsimerman. This gives another proof that the height of a partial CM-type is bounded subpolynomially in terms of the discriminant of $E$.

There is a special, Asian way of production. This is industrial and agricultural production in makhallas. The roots of crafts and entrepreneurship of mahallas go back to the distant history of Central Asia. In the Soviet period, this production was carried out in the form of small craft production. In recent years, the development of crafts and entrepreneurship in makhallas in Uzbekistan has been given the most important importance. The sectoral specialization of all mahallas has been determined in the Republic. Measures to support each of them have been planned and are being implemented. Much attention is paid to the expansion of small industries in the Mahalla environment, including handicraft, sewing, shoe and confectionery. Support is provided to those engaged in home work. More than 2000 mahallas specialize in providing various types of services. Measures are being taken for the effective use of household lands and organized spring sowing. In the agricultural sector, work is being carried out (taking into account the peculiarities of regions, districts) on the specialization of each mahalla in fruit and vegetable growing, greenhouse farming and other areas, according to the principle "one mahalla – one type of product". This gives great opportunities for finding sales markets, contributes to improving product quality, mutual transfer of experience and the development of new technologies. The policy pursued in relation to the mahallas is aimed at solving three important tasks: spiritual, political and socio-economic.

Introduction. The forest complex of Russia is a clear example of the incompatibility of established formal institutions with the preferences of economic agents. The conflict of endogenous and exogenous distribution gives rise to low economic efficiency. The correct adjustment of the institutions is possible only in conditions of compliance of the transformations with the requirements of economic agents and taking into account the influence of the "track effect". Thus, effective forest regions are characterized by a greater degree of compatibility of formal and informal institutions. The study of real market incentives of agents is possible in two ways: through the study of forms of resistance of agents to formal rules or, conversely, by studying the synergy of rules and preferences. The chain of institutional changes cannot be based solely on the elimination of the shortcomings of the system identified in the first way. The models of integration of institutions require empirical material based on the second stage of study. Materials and methods. In this article, with the help of qualitative analysis and classification methods (modeling, synthesis, comparative and induction analysis), models of formal institutions (and, accordingly, indirectly institutions) of regions institutionally close to Russia (especially countries of continental law) with competitive forest industries are studied. Results and conclusions. The boundaries of the formal model and the variables determining its character are indicated. Examples of different resource regimes and levels of ownership are considered, special attention is paid to the differentiation of state ownership of forests. The subjects of the industry regulators are specified, the classification by types of financing and functions performed is considered. Examples of relevant state forest policy instruments in the most relevant areas of development of the Russian forest complex are presented. Discussion. It is shown that in a relatively inclusive institutional environment, state regulatory entities are individualized, and endogenous distribution is characterized by an increase in collective forms of participation. The key differences between the forest policy instruments of the designated environment from the formal institutions of Russia are a lower regulatory burden and another direction of stimulating mechanisms - forestry activities.

This article presents the fundamentals and an overview of the optical-fiber-based scintillation detectors, which consist of a scintillator and an optical fiber light guide. This type of detector is preferentially used in special applications. In these applications, only a scintillator probe is placed in a severe environment, while a photodetector stays in a mild environment. Additionally, a detector should not disturb an irradiated field. As examples, applications in nuclear reactor physics experiments, medical uses, such as radiation therapies, and severe radiation conditions are reviewed.

In the early summer (June) of 2022, the spatial mean precipitation in northeast China (NEC) was 62% higher than normal and broke the historical record since 1951. Based on the precipitation data of 245 meteorological stations in NEC and the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) reanalysis, this paper analyzes the role of large-scale circulation and sea-surface temperature (SST) associated with anomalous precipitation over NEC in June using singular value decomposition (SVD), correlation analysis, regression analysis, and composite analysis methods, and further investigates the possible cause of the abnormal precipitation in June 2022. Results show that the northeast China cold vortex (NCCV) accompanying the blocking high in the Okhotsk Sea (BHOS) has been the primary mid-to-high latitude atmospheric circulation pattern affecting NEC precipitation in June since 2001. This circulation pattern is closely related to the tripole SST pattern over the North Atlantic (NAT) in March. In June 2022, the NAT SST anomaly in March stimulates eastward-propagating wave energy, resulting in the downstream anomalous circulation pattern in which the NCCV cooperates with the BHOS in the mid-high latitudes of East Asia. Under this background atmospheric circulation favorable for precipitation, the Kuroshio region SST anomaly in June led to a more northward and stronger anomalous anticyclone in the northwestern Pacific through local air–sea interaction, which provides more sufficient water vapor for NEC, resulting in unprecedented precipitation in June 2022.

The digitalisation of the building process is increasingly present on the world scene. The methodology that leads to 3D models of construction projects and buildings is called BIM (Building Information Modelling). This methodology has the great advantage of associating different types of information (spatial, temporal, structural, etc.) with the three-dimensional model, thus making it possible to create an information system that can be shared between the various stakeholders involved in the design and construction process of a building. The BIM model also becomes the basis for the development of the so-called Digital Twins, models that integrate information on the use of the building over time and provide important analysis tools for maintenance planning. The surveying methodologies for the creation of BIM most widely used today are photogrammetry and laser scanner surveying. In both cases, the product of the survey are point clouds, i.e. sets of measured points that contain information on the position of the surveyed elements and possibly their colour. Point clouds are an extremely suitable product for BIM, as they are already three-dimensional and can be queried. However, in the case of large buildings or environments with special features, surveys with traditional static lasers (on tripods) can require long time. For this reason, in recent years, the world of topographic surveying has adopted innovative instruments that allow data to be acquired in motion, thus reducing scanning and processing times, the SLAM laser scanners. Stonex has developed a solution that combines precise sensors with a robust SLAM algorithm to produce clean, and accurate point clouds easily usable for BIM creation: the new SLAM X120GO laser scanner. This system features a 360° rotating LiDAR head capable of generating a point cloud coverage of 360° x 270°. In combination with IMU data and the SLAM algorithm, it is able to obtain high-precision threedimensional point cloud data of the surrounding environment without light and GPS. Equipped with three 5MP cameras to generate a horizontal 200°FOV and vertical 100°FOV, it can synchronously obtain texture information and produce colour point clouds and partial panoramic images. Both features are very useful in the BIM authoring phase. With a range of 120 m, the X120GO is suitable for working both indoors and outdoors, even in challenging environments, allowing the survey of an entire building to be completed with a single instrument. The X120GO has an integrated structure that makes it easy to move around the scanning environment. Thanks to the GOapp Android application, you can manage the scanner and observe the creation of the point cloud in real time. Once the start button is pressed, the X120GO can begin operations immediately, making data acquisition efficient and convenient. During data acquisition, the X120GO is also able to collect control point coordinates, which can then be combined with known points to georeference scans.
