User content as a marketing strategy tool: basic structural elements, principles, benefits and risks of use

Introduction.The processes of globalization and digitization of all economic activities necessitate the updating of methods and tools for promoting goods and services. According to WhatstheBigData, in 2022, the number of smartphones was 6.42 billion units, and in 2023, this figure increased by 297 million. Experts predict that by 2028, the number of smartphones will reach 7.74 billion. This, in turn, triggers an increase in the number of social media users and simplifies communication with consumers. Furthermore, the emergence of new technologies leads to the transformation of communications among all stakeholders. Artificial intelligence tools enable the creation of content and ideas for promotion, taking into account the emotional tone of the target audience, the value of the product, brand, etc. The aim of this paper is to systematize the theoretical and practical basis of UGC, determine the volumes and risks of the market. Methods.The research is based on publicly available information, studies of users’ emotional reactions, and open economic indicators of the user-generated content market. Results. The effectiveness of existing digital tools depends on several factors: 1) content quality and information noise. Instagram users upload 1,099 pieces of content every second, leading to overload, requiring brands to spend more time retaining the attention of their target audience; 2) level of competition. Clear content creation algorithms, user-friendly online dashboards, and relatively low costs result in high competition levels. According to Statista, the number of active Facebook advertisers reached 10 million companies in 2020; 3) algorithm for ranking organic and commercial content. Social networks constantly update their algorithms, which necessitates continuous content updates considering these algorithm and technology changes. According to various studies, four main methods of promotion on social networks are identified: influencer advertising, content marketing, organic promotion, and targeted advertising. Additionally, marketing experts note that user- generated content (UGC) saw significant growth in 2023. The specificity of UGC lies in its creation by the audience of social networks, messengers, and streaming platforms. Its emergence was somewhat triggered by information noise and inauthentic content. Users began sharing personal impressions about products, services, or companies in general. This content is mostly organic, requiring prior preparation and differing in effectiveness and the inability to fully control or predict results. For example, the effectiveness of targeted advertising can be preliminarily determined in the ad manager, while promotion through influencers is based on the analysis of their profile statistics. According to Scopus, 2023 was the most active year for publications on user-generated content. Researchers published 398 papers on the analyzed topic within the fields of business, economics, management, and social sciences. Ukrainian marketing agencies are incorporating UGC into their advertising strategies. For instance, Genius Space and SendPulse use the tool to promote educational courses. Domestic retail chains such as Eva, Avrora, and Silpo are forming marketing campaigns based on UGC. In 2024, the market value has already been estimated at over $4 billion. In the USA, a full-fledged profession – “UGC Creator” – has emerged, which is also starting to appear in Ukraine. Thus, the topic is relevant among both researchers and entrepreneurs. However, the reasons for its emergence, structure, and risks of use are not structured. he advantages and risks of using user-generated content in marketing campaigns. Directions for further investigations. Further research is needed to determine the effectiveness of user-generated content compared to other marketing tools based on statistical indicators. Additionally, methods for minimizing existing risks and identifying further modernization of the tool need to be found. In particular, content created by artificial intelligence is already being actively discussed in scientific communities in 2024. For user- generated content, this could pose a significant threat, so it is necessary to determine the place of “artificial content” within marketing promotion in the future.

Statistical Mechanics of Directed Networks.

Directed networks are essential for representing complex systems, capturing the asymmetry of interactions in fields such as neuroscience, transportation, and social networks. Directionality reveals how influence, information, or resources flow within a network, fundamentally shaping the behavior of dynamical processes and distinguishing directed networks from their undirected counterparts. Robust null models are crucial for identifying meaningful patterns in these representations, yet designing models that preserve key features remains a significant challenge. One such critical feature is reciprocity, which reflects the balance of bidirectional interactions in directed networks and provides insights into the underlying structural and dynamical principles that shape their connectivity. This paper introduces a statistical mechanics framework for directed networks, modeling them as ensembles of interacting fermions. By controlling the reciprocity and other network properties, our formalism offers a principled approach to analyzing directed network structures and dynamics, introducing new perspectives and models and analytical tools for empirical studies.

Finite Element Analysis of Electromagnetic Characteristics of a Single-Phase Permanent Magnet Linear Oscillation Actuator.

The electromagnetic characteristics of a single-phase permanent magnet linear oscillation actuator are analyzed by the finite element method. Firstly, the basic structure and operation principle of the linear oscillation actuator are introduced. The internal stator slot and arc tooth are used to reduce the detent force. According to the principle of electromagnetic fields, the electromagnetic field equation is listed and the function of the motor is deduced. At the same time, the eight-node hexahedral element is used to calculate the listed universal functions, and the inductance, flux linkage, induced electromotive force and electromagnetic force of the motor are deduced. The electromagnetic field of the motor is simulated by two-dimensional and three-dimensional finite element methods, and the accuracy of the calculation results of the electromagnetic characteristics of the cylindrical linear oscillation motor by the two methods is compared and analyzed. Finally, an experimental prototype was developed and the no-load characteristics of the motor were tested using the existing linear motor towing method. By comparing the experimental and simulation results, the accuracy of the theoretical analysis and the rationality of the motor design are verified.

Principles of visual cortex excitatory microcircuit organization.

Synapse-specific connectivity and dynamics determine microcircuit function but are challenging to explore with classic paired recordings due to their low throughput. We therefore implemented optomapping, a ∼100-fold faster two-photon optogenetic method. In mouse primary visual cortex (V1), we optomapped 30,454 candidate inputs to reveal 1,790 excitatory inputs to pyramidal, basket, and Martinotti cells. Across these cell types, log-normal distribution of synaptic efficacies emerged as a principle. For pyramidal cells, optomapping reproduced the canonical circuit but unexpectedly uncovered that the excitation of basket cells concentrated to layer 5 and that of Martinotti cells dominated in layer 2/3. The excitation of basket cells was stronger and reached farther than the excitation of pyramidal cells, which may promote stability. Short-term plasticity surprisingly depended on cortical layer in addition to target cell. Finally, optomapping revealed an overrepresentation of shared inputs for interconnected layer-6 pyramidal cells. Thus, by resolving the throughput problem, optomapping uncovered hitherto unappreciated principles of V1 structure.

Modelling and application of yaw damper with frequency-selective damping on railway vehicles

In this study, a new mechanical yaw damper with frequency-selective damping (FSD) is investigated. The structure principle, modelling and simulation of the damper and its core component, the frequency-selective damping valve, are elaborated. Compared with the conventional damper, the static and dynamic characteristics of the FSD damper have been tested in the experimental bench, and the damping variation rate is proposed to evaluate the damping force variation. A physical parameter model of the yaw damper is established by using the AMESim software, and the simulation accuracy has been verified by comparing the simulated results with the experimental ones. A detailed analysis has been performed for the influence of key parameters of the FSD valve on the mechanical characteristics of the FSD damper. Finally, through the AMESim/Simpack co-simulation method, the dynamic performances of a high-speed locomotive equipped with the FSD yaw damper have been simulated. The results indicate that the FSD yaw damper improves the adaptive stability of railway vehicles in different wheel–rail matching states. In addition, the dynamic performance of the vehicle can be improved when passing through the turnout and narrow curves.

Optimization on Reasonable Construction State for Cable-Stayed Bridge with Steel Box Girder Based on Multi-Objective Programming Algorithm

The reasonable construction state of a cable-stayed bridge refers to the state achieved after construction is carried out according to a specific sequence of procedures, leading to the reasonable completion status the bridge. The corresponding construction states at each stage are considered as part of the reasonable construction state. For the optimization of the construction state of cable-stayed bridges with steel box girders, a method combining a multi-objective programming algorithm with a forward iteration method is proposed to determine a reasonable construction state based on the structural characteristics and optimization principles of such bridges. First, a multi-objective programming model was established, taking the bending moments of the main girder and pylon, as well as cable forces, as objective functions. The weighted square sum method, a type of evaluation function method, was then employed to convert the multi-objective programming model into an unconstrained single-objective quadratic programming model. Subsequently, the damped Newton method was utilized to solve the quadratic programming problem. By integrating this algorithm with the forward iteration method, the reasonable construction state of a large-span and double-tower steel box girder cable-stayed bridge was optimized. The influence of different objective functions on the optimization results was analyzed. The findings demonstrate that the proposed method produces a smooth structural configuration under the optimized construction state, with internal forces and normal stresses within a reasonable range. In the completed state derived from this construction state, internal forces, normal stresses, and cable forces are uniformly distributed, while the reactions at transition piers and auxiliary piers exhibit sufficient pressure reserves. The structural state under dead load achieved through this method closely aligns with the desired reasonable completed state.

НАСЛЕДОВАНИЕ АНСАМБЛЕЙ ЦИКЛИЧЕСКИХ СТРУКТУР И СВЯЗЬ ГЕНЕТИЧЕСКОГО КОДИРОВАНИЯ С ЦИКЛИЧЕСКИМИ КОДАМИ ГРЕЯ И БУЛЕВЫМИ ФУНКЦИЯМИ

The article is devoted to the problem of genetic inheritance of ensembles of mutually coordinated cyclic processes, whose huge choir is the basis of each living organism. It is shown that the structural organization of the genetic coding system is associated with Gray cyclic codes and Karnaugh maps from the Boolean Algebra of Logic. In this regard, this system can be considered as a cyclic coding system associated with Boolean functions. On the basis of the well-known experimental data, the following provision is put forward and justified: the genetic system carries on itself, in addition to the well-known genetic code of amino acid sequences of proteins, also the genetic code of the Boolean functions encoded by n-plets of DNA and RNA, for the inherited ensuring the logically consistent interactions of the body's parts. Accounting for this second, that is Boolean-logical code, allows you to naturally explain a number of difficult problems of genetics, and also opens the way to understand the logical conjugation of many inherited physiological processes. A new understanding is proposed for the phenomenon of using of rhythms and cycles in the creativity works of people - in music, poetry, architecture, etc.: this phenomenon can reflect the unconscious desire of people to reproduce in their creations those principles of structuring, in accordance with which they are built themselves.

Национально-территориальное устройство СССР: «мина замедленного действия» или «исторический компромисс»?

The article attempts to refute the widespread opinion in historiography that the form of organization of the USSR, consisting of ethnoterritorial formations of different status, was one of the main factors in the collapse of a single state. It is argued that the idea of federalization of Russia did not belong to the Bolsheviks, but to national parties and movements that demanded recognition of their right to national-territorial autonomy. The article substantiates the position that the national-territorial principle of the internal structure of the Soviet state contributed both to the preservation and strengthening of the national identity of Soviet ethnic groups and to the creation of a civil nation in the form of the Soviet people as a new historical community.

Functional Neuroanatomy of the Normal and Pathological Basal Ganglia.

The term "basal ganglia" refers to a group of interconnected subcortical nuclei engaged in motor planning and movement initiation, executive functions, behaviors, and emotions. Dopamine released from the substantia nigra is the underlying driving force keeping the basal ganglia network under proper equilibrium and, indeed, reduction of dopamine levels triggers basal ganglia dysfunction, setting the groundwork for several movement disorders. The canonical basal ganglia model has been instrumental for most of our current understanding of the normal and pathological functioning of this subcortical network. This model explains how cortical information flows through the basal ganglia nuclei back to the cortex by going through two pathways with opposing effects that together lead to the proper execution of a given movement. The basal ganglia model has paved the way for the standard clinical management of Parkinson's disease, where pharmacological and neurosurgical treatments in place collectively afford an impressive symptomatic alleviation. Although much of the model has remained, the canonical model has been enriched with new arrivals gathered from evidence provided in the last three decades. Here, we sought to provide a comprehensive review of the basal ganglia network, with emphasis on structure, connectivity patterns, and basic operational principles, both in normal and pathological conditions.

Design of Polarization Spectroscopy Integrated Imaging System

To simultaneously acquire the spectral and polarization information of the target and achieve the monitoring and identification of the target object, a polarization spectral integrated imaging system is proposed in this paper. Firstly, the structural principle of the polarization spectral integrated imaging system is introduced. The relationship between the spatial resolution, spectral resolution, and the system’s structural parameters is analyzed. The design of the optical part of the polarization spectral integrated imaging system is completed, along with the tolerance analysis. Secondly, the mechanical structure of the polarization spectral integrated imaging system is designed. Finally, by using a drone to carry the polarization spectral integrated imaging system, a simulation experiment for sea surface oil spill monitoring is conducted, and the hyperspectral and polarization information of the ocean, crude oil, fuel oil, palm oil, diesel, and gasoline are obtained. The polarization and spectral information were integrated. The integration of hyperspectral and polarization data yields remarkable enhancement outcomes, allowing for the clear delineation of previously challenging-to-identify crude oil contamination areas against the marine background in the fused images, characterized by sharper boundaries and improved discriminability. This accomplishment underscores the feasibility of our system for the rapid identification of large-scale oil spill events.

Advanced Neural Probe Sensors toward Multi‐Modal Sensing and Modulation: Design, Integration, and Applications

AbstractNeural probe devices have undergone significant advancements in recent years, evolving from basic single‐functional devices to sophisticated integrated systems capable of sensing, stimulating, and regulating neural activity. The neural probes have been demonstrated as effective tools for diagnosing and treating numerous neurological disorders, as well as for understanding sophisticated connections and functions of neuron circuits. The multifunctional neural probe platforms, which combine electrical, optical, and chemical sensing capabilities, hold promising potential for revolutionizing personalized healthcare through closed‐loop neuromodulation, particularly in the treatment of conditions such as epilepsy, Parkinson's disease, and depression. Despite these advances, several challenges remain to be further investigated, including biocompatibility, long‐term signal quality and stability, and miniaturization, all of which hinder their broader clinical application. This paper provides an overview of the design principles of the neural probe structures and sensors, fabrication strategies, and integration techniques for the advanced multi‐functional neural probes. Key electrical, optical, and chemical sensing mechanisms are discussed, along with the selection of corresponding functional materials. Additionally, several representative applications are highlighted, followed by a discussion of the challenges and opportunities that lie ahead for this emerging field.

THE ROLE OF THE PUBLIC PROSECUTOR'S OFFICE WITHIN CRIMINAL PROCEEDINGS

The public prosecutor’s office is an independent state body tasked with protecting constitutionality and legality. It this regard, the prosecutor’s office is responsible for prosecuting perpetrators of criminal offenses ex officio. The majority of criminal offences in the Republic of Serbia fall into this category, meaning that a significantly smaller number of offences are prosecuted by private complaint, which depends solely on the will of the injured party. The author first of all examines the historical development of the public prosecutor’s office, which has its roots in France. In the early XIX century, French Code d’instruction criminelle formalized the role of prosecutors as essential participants in the court proceedings, a practice that proved highly effective. The French model was later adopted by other European countries. The paper aims to define the public prosecutor’s office in the context of its organization, focusing on the principles that underpin this state body. These principles exist to ensure the office operates as efficiently as possible. They include the principles of indivisibility, unity, hierarchical structure and monocratic decision-making. The author provides a detailed analysis of each of these principles, thereby offering deeper insight into the organization of the public prosecutor’s office. Particular emphasis is placed on the position of the public prosecutor in the criminal proceedings, as one of the main criminal procedure actors, alongside the criminal court and the defendant. The prosecutor’s role is most easily defined through the analysis of the rights and duties assigned by law. Therefore, the author outlines the role of the public prosecutors not only during the main trial, but also during the investigation, emphasizing their authority to represent the prosecution in the public interest. The public prosecutor is obliged to present the court with relevant evidence showing that the accused has indeed committed the offence in question, which will result in a conviction and the satisfaction of justice. In this regard, the author highlights the role of the police, other state bodies, and all natural and legal persons who are obliged to provide the requested information to the prosecutor if so required. The public prosecutor may propose that the criminal court examine a person as a witness, believing that the individual possesses useful information about the perpetrator and the circumstances under which the crime was committed (location, motive, potential accomplices, etc.). The author’s intention is for the research results to underscore the necessity of good organization and regulation of the position of the public prosecutor’s office, as this is the only way to ensure the effective protection of social goods. These goods primarily relate to a wide range of fundamental human rights guaranteed by both domestic and international legal acts. In conclusion, the author stresses the importance of legal regulation of criminal proceedings because convictions can deprive individuals of their right to freedom for an extended period. For this reason, the author clearly points out the need for fairness in the proceedings, which also applies to the conduct of the public prosecutor, who is obliged to present both inculpatory and exculpatory evidences before the court. Finally, author addresses the anomalies faced by certain states regarding the independence of the public prosecutor’s office, providing recommendations to eliminate, primarily, political influence on the work of public prosecutors.

Architecture of the high-affinity immunoglobulin E receptor.

The high-affinity immunoglobulin E (IgE) receptor (FcεRI) drives type I hypersensitivity in response to allergen-specific IgE. FcεRI is a multimeric complex typically composed of one α, one β, and two disulfide-linked γ subunits. The α subunit binds to the fragment crystallizable (Fc) region of IgE (Fcε), whereas the β and γ subunits mediate signaling through their intracellular immunoreceptor tyrosine-based activation motifs (ITAMs). Here, we report cryo-electron microscopy (cryo-EM) structures of the apo state of FcεRI and of FcεRI bound to Fcε. At the transmembrane domain (TMD), the α and γ subunits associate to form a tightly packed, three-helix bundle (αγ2 bundle) with pseudo-threefold symmetry through extensive hydrophobic and polar interactions. The αγ2 bundle further assembles with the β subunit to complete the TMD, from which multiple ITAMs might extend into the cytoplasm for downstream signaling. The apo mouse FcεRI essentially forms an identical structure to that of the Fcε-bound sensitized form, suggesting that the binding of Fcε to FcεRI does not alter the overall conformation of the receptor. Furthermore, the juxtamembrane interaction between the extracellular domains (ECDs) of mouse FcεRIα and FcεRIβ is not observed between their human counterparts, which implies potential species-specific differences in receptor stability and activation. Our findings provide a framework for understanding the general structural principles underlying Fc receptor assembly, the signaling mechanism underlying type I hypersensitivity, and the design of efficient antiallergic therapeutics.

This paper explores the features of the popular open-source library from the .NET ecosystem MediatR, which implements the behavioral software design pattern Mediator to achieve loose coupling and better communication between the components of developed applications. It introduces an ‘in-process’ mediator, which aids in building systems, based on the Command and Query Responsibility Segregation software design pattern (CQRS). The MediatR library offers the ability to handle both synchronous and asynchronous requests, responses, commands, notifications, and events. It provides a straightforward approach for managing command and request handlers, simplifying the adoption of CQRS. Using the MediatR library improves the modularity and testability of .NET applications by promoting adherence to SOLID principles in the code structure. This facilitates complex interactions between different parts of applications, the integration of new functionalities and the maintenance of existing ones.

A SiC Photo-Conductive Switch-Based Pulse Generator with Nanoseconds and High Voltage for Liver Cancer Cells Ablation Therapy

Electroporation ablation, as an innovative cancer treatment, not only preserves the structure and function of affected organs but also significantly reduces surgical risks, offers patients a safer and more effective therapeutic option, and demonstrates immense potential in the field of oncology. This paper presents the innovative design of a high-voltage nanosecond pulse generator triggered by a silicon carbide (SiC) photoconductive switch. The generator is capable of stably outputting adjustable voltages ranging from 10 kV to 15 kV, with pulse widths precisely controlled between 10 and 15 nanoseconds, and an operating frequency adjustable from 1 Hz to 10 Hz. This device enables instant activation and deactivation of the pulse generator during ablation, enhancing the efficiency of strong electric field applications and preventing overtreatment due to delayed shutdown. This paper introduces the structure and basic principles of this novel SiC photoconductive switch-triggered pulse device and reports on the impact of device-related pulse parameters on the ablation effect of hepatocellular carcinoma cells through cell experiments. Under optimal ablation parameters, the CCK8 results show that the number of viable cells is only 0.7% of that in the untreated control group after 12 h of subculture following ablation. These findings hold significant importance for expanding the application areas of SiC devices.

On the textual problems of publishing the novel “Demons” as a part of the Complete Works of F. M. Dostoevsky (1974 and 2021)

The article contains an analysis of the texts of two academic publications of F. M. Dostoevskyʼs novel “Demons” – as a part of the Complete Works in 30 volumes (1972–1990) and the currently published Complete Works in 35 volumes. The textual and historical-literary problems associated with these publications are analyzed, the methodology and errors characteristic of each of the publications are considered, the pros and cons of both publications are analyzed. The importance of the issue of the fundamental discrepancy between punctuation of the 19th century and the modern norm, based primarily on the structural and semantic principle of punctuation marks and developed in much more detail than the codes of the 19th century, is pointed out. The preservation of individual elements of archaic punctuation when reading a text by a carrier of a modern punctuation norm has a destructive effect on meaning. The article considers a number of examples showing the inapplicability of elements of old spelling and punctuation in the modern traditional academic tradition.

Study of a Companion Trajectory Kinematics Analysis Method for the Five-Blade Rotor Swing Scraper Pump

This paper proposes a five-blade rotor swing scraper pump (FRSSP) to overcome traditional volumetric pumps’ drawbacks, such as poor sealing performance, low volumetric efficiency, and complex structure. This pump employs a rotating cam-swing scraper mechanism to achieve fluid intake and discharge. The FRSSP is compact in structure, self-sealing, and highly efficient in volumetric utilization, offering promising applications. A companion trajectory kinematic analysis method of the FRSSP is proposed. The polar coordinate equation of the companion trajectory is derived from the profile equation of the five-blade rotor cam. Based on this trajectory, a kinematic model of the scraper pump is established, resulting in the kinematic equations for the swing angle of the scraper, the pressure angle of the scraper, the rotation angle of the rotor, the angular velocity of the scraper, and the angular acceleration of the scraper. The kinematics of the FRSSP were simulated and validated using ADAMS. Comparing the results of theoretical calculations and simulation reveals that the error in the scraper swing angle is 1.85%, the maximum error in the scraper angular velocity is 4.93%, and the maximum error in the scraper angular acceleration is 2.47%, confirming the accuracy of the kinematic analysis method. A sensitivity analysis was performed on the kinematic research method for companion trajectories. After modifying the dimensions of key components in the scraper pump, the discrepancies between theoretical calculations and simulation results were within 5%, confirming the accuracy and robustness of the method. Flow field simulation analysis and experimental tests on the scraper pump revealed that the deviation between the simulated and experimental outlet flow rates was less than 5%, validating the feasibility of the pump’s structural principles and the reliability of the simulations. Furthermore, these findings indirectly affirmed the correctness of the companion trajectory kinematic analysis method.
