Annotation: This article reviews various hardware methods used to treat cellulite, improve skin tone and model body contours. The main goal of the work was to show how these approaches differ from each other and what clinical results can be expected when using them, based on the analysis of already published studies. Standard scientific approaches were used in the work - analysis and generalization of data, comparison of results and systematization of information from various sources. The results obtained indicate that hardware methods for correcting cellulite differ significantly both in terms of mechanisms of action and in the severity and duration of the effect. Radiofrequency therapy mainly affects the dermis, promoting collagen remodeling and increasing skin elasticity, but its ability to eliminate cellulite depressions is usually limited. Extracorporeal shock wave therapy demonstrates a noticeable reduction in the severity of cellulite, which is associated with improved microcirculation and activation of regenerative processes in tissues, although the optimal regimens for its use remain the subject of further research. Mechanical vacuum-assisted therapy provides rapid visual improvement by reducing swelling and congestion, but this effect is usually temporary and requires regular repetition of procedures. Laser techniques, in turn, have proven to be a heterogeneous group: low-intensity laser therapy gives conflicting results, while laser-assisted subcision demonstrates a more stable improvement in skin structure and a reduction in cellulite, especially in the thighs and buttocks. Vibration exercises mainly affect muscle activity and body composition, so it is advisable to consider them as an auxiliary element in complex programs, and not as an independent method of cellulite correction. Subcision, although it is the most invasive approach, shows the most pronounced effect in cases of deep cellulite indentations, since it directly eliminates the mechanical factors of their formation. The practical significance of the analysis is that it allows a more reasoned approach to the choice of hardware techniques, adapting the treatment tactics to the type of cellulite, skin condition and expected clinical result, which is key for individualized correction.

Annotation: The article addresses the challenge of automating architectural quality control in microservice systems designed using Domain-Driven Design methodology. A comparative analysis of the effectiveness of deterministic methods and probabilistic methods was conducted. Using a simulated e-commerce system with a controlled set of defects, a quantitative assessment of Precision and Recall metrics was performed for both approaches. The experiment confirmed that deterministic methods ensure absolute precision in detecting structural boundary violations but exhibit "semantic blindness" regarding complex DDD patterns. Conversely, probabilistic methods demonstrated high effectiveness in identifying semantic defects, such as anemic domain models and context leakage, with an acceptable level of false positives. Based on the results, the necessity of implementing a hybrid verification strategy is substantiated, where static analysis acts as a rigid gatekeeper in CI/CD pipelines, while AI tools serve as an intelligent architect's assistant.

Annotation: The article is dedicated to the study of the efficiency of web applications built on the Laravel framework in different PHP runtime environments, such as PHP-FPM, Apache/mod_php, and Nginx. It also covers high-performance solutions based on long-lived processes, like Swoole and RoadRunner, as well as Laravel Octane. A comparative analysis of the architectural features, startup costs associated with the framework, and the impact of different server configurations on bandwidth and HTTP request processing delays was conducted. Based on the experimental data from synthetic tests and real-world cases, recommendations were formulated for selecting a runtime environment and optimizing Laravel apps for different workload scenarios.

Annotation: This article presents a multilingual analysis of expressiveness in English and Ukrainian, considering their typological, cultural, and communicative characteristics. The study examines the main lexico-semantic, morphological, syntactic, and phonetic-prosodic means through which expressiveness is achieved. Examples of linguistic units are provided to illustrate various mechanisms for conveying emotionality and imagery. The research identifies both shared and distinctive features of expressive expression in the two languages. The findings indicate that English expresses emotion primarily through contextual and logical strategies, while Ukrainian is marked by high emotional intensity, morphological productivity, and intonational expressiveness.

Annotation: The article examines the microbiological risks associated with the nail industry and analyzes the main stages of ensuring safety during manicure and pedicure procedures. Particular attention is given to three key processes: cleaning, disinfection, and sterilization of instruments. The dangers of reusing consumables—such as buffers, files, and gloves—which can accumulate pathogenic microorganisms and contribute to infection transmission between clients, are highlighted. The study provides a comparative analysis of sterilization methods, including dry-heat sterilizers, autoclaves, and ultrasonic baths, assessing their effectiveness, advantages, and limitations. The principles of organizing a safe working environment are also described, including proper storage of sterile instruments, maintaining documented sterilization logs, and adherence to personal hygiene by technicians. The findings emphasize the need for a systematic approach to cleanliness control and sanitary standards in nail services to reduce the risk of infectious complications, improve service quality, and ensure the safety of both clients and specialists.

Annotation: It has been established that multimodality and multimodal metaphors combine various sign systems (visual, verbal, auditory, etc.) to create complex meanings in contemporary discourses and cultural texts.
