Experimental realizations of information engines: Beyond proof of concept
Authors: Goerlich Remi , Hoek Laura , Chor Omer , Rahav Saar , Roichman Yael
Published: February 2025

Gathering information about a system enables greater control over it. This principle lies at the core of information engines, which use measurement-based feedback to rectify thermal noise and convert information into work. Originating from Maxwell's and Szilárd's thought experiments, the thermodynamics of information engines has steadily advanced, with recent experimental realizations pushing the field forward. Coupled with technological advances and developments in nonequilibrium thermodynamics, novel implementations of information engines continue to challenge theoretical understanding. In this perspective, we discuss recent progress and highlight new opportunities, such as applying information engines to active, many-body, and inertial systems and leveraging tools like optimal control to design their driving protocols.
Jewish Revenge on the German Screen
Authors: Landry Olivia
Published: February 2025

Post-Holocaust German cinema is rife with the figure of the Jewish victim and accompanying portrayals of Jewish German and non-Jewish German reconciliation. Instrumental in this tradition, heritage filmmaking of the 1990s manufactured undemanding and sentimental historical tales for a mass audience. More recently, a crop of new films does something radically different. This essay tracks Jewish revenge plots in contemporary German film. Films such as Ende der Schonzeit (Closed Season, dir. Franziska Schlotterer, 2012), Winterjagd (Winter Hunt, dir. Astrid Schult, 2017), Masel Tov Cocktail (dir. Arkadij Khaet and Mickey Paatzsch, 2020), and Plan A—Was würdest du tun? (Plan A—What Would You Do?, dir. Yoav Paz and Doron Paz, 2021) challenge what has come before. In pursuit of different historical narratives, they embrace the Jewish revenge fantasy and hail the diverse possibilities of new Jewish positions. Finally, partaking of a shift in memory culture toward anger, resistance, and self-empowerment advanced by the author and curator Max Czollek, among others, these films usher in a new era for culture and cinema alike.

In interspecific signalling, vivid colours have been interpreted to enable species recognition and maximise signal detection. Recently, it has been shown that vivid colours can also convey information on individual fitness which could be advantageous for receivers. In the marine cleaning mutualism between the Indo-Pacific Bluestreak cleaner wrasse Labroides dimidiatus and their reef fish visitors (known as clients), the colour of cleaners may provide behavioural cues, which clients could use to make decisions, as higher blue saturations associate with better cleaning services. Here we asked if clients perceived differences in blue saturation when evaluating individual cleaners, and if they used this information to choose them. To do this we introduced the client threadfin Butterflyfish (Chaetodon auriga) to three differently saturated video-sequences of cleaners (minimum saturation, control, and maximum saturation). We found that clients actively preferred video-sequences of more saturated cleaners when played against lower saturations (by spending more time, facing more frequently, and during longer periods more saturated blue video sequences, and entering the preference areas near the more saturated monitors more frequently), which provided more evidence that the blue colouration of cleaners may be a true signal of individual quality. By being able to distinguish these saturations it is likely that in the wild, clients use this signal to make decisions and select the cleaners that provide a better cleaning service.

Published: February 2025

Gill regeneration in fish varies inter and intra-specifically. The latter may be associated with myriad factors including capacity of energy metabolism. This study investigated whether mitochondrial respiration capacity influences the degree of gill regeneration, and features of mitochondria in regenerated tissue by feeding fish an experimental diet aimed at modulating mitochondrial efficiency. Fish reared on control and experimental diet were subjected to 50% filament resection on a subset of filaments on the ventral and dorsal regions of the first gill arch. Mitochondrial respiration and citrate synthase activity (CSA) were measured in the resected tips of filaments (week-0) and then in the regenerated tissue at week-20 post-resection. The degree of filament regeneration was measured at week-20 post-resection (week-20). The experimental diet reduced CSA and respiratory control ratio (RCR), and increased proton leak at week-0 which was associated with a 30% reduction in tissue regeneration compared to fish on standard diet. While CSA increased in the regenerated tissue at week-20, there was a decline in state 3 respiration, proton leak, complex IV activity, and RCR as compared to week-0 irrespective of diet. Overall, mitochondrial respiration efficiency at week-0 was positively correlated with the degree of subsequent gill tissue regeneration. Additionally, state 3 respiration and proton leak at week-20 were positively correlated with tissue regeneration, whereas CSA exhibited a negative relationship. Our results indicate that capacity of mitochondrial respiration may at least partially explain the inter-individual variations in tissue regeneration, but mitochondrial function in the regenerating tissue may be limited.

Published: February 2025

For gap-crossing agility, arboreal animals require the ability to stabilize dynamic landings on branches. Despite lacking a prehensile grip, squirrels achieve stable landings using a palmar grasp. We investigated the landing dynamics of free-ranging fox squirrels (Sciurus niger) to uncover strategies for stable, above-branch landings. Using high-speed video and force-torque measurements in the sagittal plane, we quantified landing kinetics across gap distances. Squirrels rapidly managed >80% of the landing energy with their forelimbs. With larger gaps, peak leg force and foot torque increased. Alignment between forelimbs, velocity, and force increased, likely reducing joint moments. We tested control hypotheses based on an extensible pendulum model used in the physical, hopping robot named Salto. Squirrels stabilized off-target landings by modulating leg force and foot torque. To correct for undershooting, squirrels generated pull up torques and reduced leg force. For overshooting, squirrels generated braking torques and increased leg force. Embodying control principles in leg and foot design can enable stable landings in sparse environments for animals and robots alike, even those lacking prehensile grasps.

Authors:   LLC «BELROSAKVA», Burak Leonid Ch. , Ovsyannikova Nataliya L. ,   LLC «BELROSAKVA»
Published: February 2025

The shelf life of garden strawberry fruits when stored under recommended conditions is about a week. Due to microbiological spoilage and seasonal availability of fruits, the issues of their long-term storage are relevant. Various methods of post-harvest treatment have been used to prevent microbial contamination and extend the shelf life of garden strawberries. The purpose of this study is to review modern post-harvest methods of garden strawberry fruits treatment to reduce microbiological spoilage and extend the shelf life of berries. A review of scientific publications and electronic resources for the period from 2012 to 2024 was conducted. The search for relevant literature was carried out by keywords through scientific databases such as Scopus, Web of Science and RSCI, as well as using the Google Scholar system. The study included papers published in English and Russian. Traditionally, thermal, plasma, radiation, chemical and biological treatments are used to preserve fruits after harvesting and extend their shelf life. In recent decades, modern environmentally friendly technologies have been developed, including modified and controlled atmosphere packaging, packaging based on active biopolymers or edible coatings. These methods can significantly increase the shelf life of fruits, as well as ensure the preservation of the quality and safety of raw plant materials. The first part of this review examines the metabolic and biochemical processes that underlie the ripening process of garden strawberries and provides an analysis of the factors causing spoilage of garden strawberries. This review may be of interest to the scientific community, as well as to specialists in the agro-industrial complex involved in the harvest and sale of fruits and berries.

Authors: Lee Si-Young , Yoon Hye-Young
Published: February 2025

Objectives: The aim of this study was to identify and compare the properties associated with the biofilm-forming abilities of bacteria isolated from water in dental unit waterlines (DUWLs). Methods: Twelve bacterial strains isolated from the output water of DUWLs were cultured in 12-well plates containing polyurethane tubing and R2A medium. The amount of biofilm formed by each strain was evaluated. Based on the amount of biofilm formed, three strains were selected, and the level of adhesion was determined for each strain depending on the inoculation concentration and incubation time. In addition, adhesion inhibitors were identified in the three strains, and their hydrophobicity and extracellular polymeric substances (EPS) formation were compared. Results: Among the 12 strains, the highest levels of biofilm accumulation were seen in Cupriavidus pauculus HY12. C. pauculus HY12 showed higher levels of adhesion at lower bacterial concentrations and shorter incubation times than other strains. The adhesion of C. pauculus HY12 was inhibited by trypsin. Among the three isolates, hydrophobicity and EPS production were the highest in Acidovorax delafieldii HY1. Conclusions: The results of this study provide a basis for understanding the mechanism of DUWL biofilm formation and the development of methods to inhibit biofilm formation.
Spinning Bodies into Gold: Thread, Labor, and Choice in Karen Russell’s “Reeling for the Empire” and Paul Thomas Anderson’s Phantom Thread
Authors: Greenhough Amy
Published: February 2025

Abstract: This article uses the tale of “Rumpelstiltskin” as a framing device to explore Paul Thomas Anderson’s feature film Phantom Thread (2017) and Karen Russell’s short story “Reeling for the Empire” (2013) as contemporary fairy tales that illuminate the relationship thread, production, and bodies have to exploitation, specifically in relation to gender. It argues that Anderson and Russell both draw on fairy tale to examine the murky exchanges embedded in advanced capitalist modes of production.
Trans-Species Fairy-Tale Femininities: The Criticality and Performativity of Human-Nonhuman Costuming in Antonín Dvořák’s Opera Rusalka
Authors: Barbieri Donatella
Published: February 2025

Abstract: Staged interpretations of Antonín Dvořák’s Rusalka , kin to other aquatic fairy-tale characters such as Andersen’s “The Little Mermaid,” can situate the opera in trans-species, postcolonial, and new materialist approaches by positioning costume not simply as representational, but as matter actively performing moments, worlds, and transformations. Through distributed agency, the costuming of human-nonhumanity intersects multiple other power imbalances, particularly when engaging the pre-Christian rusalki , mythical antecedents that regulated elemental forces in Slavic folklore, illuminating ecofeminist readings pertinent in addressing climate change. Through costume, this fairy-tale opera raises consciousness on entangled social and environmental concerns, affecting performance and consequently the audience.
A Hood Is Not a Hat: On Translating Fairy-Tale Fashion
Authors: Fraser Lucy
Published: February 2025

Abstract: This article explores the process of translating Ogawa Yōko’s short story, “Zukin kurabu” (The Riding Hood Club) from Japanese into English, with a focus on the theme of fashion, clothing, and costume, and against the backdrop of the history of Japanese translations of Perrault’s and the Grimms’ stories of “Little Red Riding Hood.” The article considers how the translation process itself may inform an investigation into fashion and sewing in fairy-tale retellings across languages and cultures. Translating this story, with reference to its accompanying illustrations, highlighted the complex functions of ideas of “Japanese-ness,” “Western-ness,” and gender in Japanese retellings of European fairy tales.
N-path quantum interference and hypergraphs
Authors: Duarte Francisco
Published: February 2025

It is elucidated that N-slit, or N-path, quantum interference utilizes the intrinsic nonlocality of the photon to illuminate simultaneously from the source the entire N-slit array thus allowing the characterization of the interference via the Dirac-Feynman interferometric principle. This simultaneous illumination of N-paths also applies to the Feynman path integral formulation of quantum mechanics. This quantum mechanism of simultaneous and whole illumination of N-slits, or N-paths, is quite different to the sequential illumination of N-paths via the hypergraph methodology where the N is achieved via the classical diagrammatical binary sequence 1, 2, 4, 8, 16, 32, … .
Immunoinformatic evaluation for the development of a potent multi-epitope vaccine against bacterial vaginosis caused by Gardnerella vaginalis
Authors: Motamedi Hamid , Shoja Saeed , Abbasi Maryam
Published: February 2025

Background

Bacterial vaginosis (BV) is the most common vaginal dysbiosis in fertile women, which is associated with side effects including the risk of premature birth. Gardnerella vaginalis (G. vaginalis) is a facultative anaerobic bacillus known as the main pathogen responsible for BV. In this study, using bioinformatics and immunoinformatics methods, a multi-epitope vaccine with optimal population coverage against BV caused by G. vaginalis was designed.

Methods

Amino acid sequences of two important virulence factors (Vaginolysin and Sialidase) of G. vaginalis were retrieved from NCBI and UniProt databases. At first, three online servers ABCpred, BCPREDS and LBtope were used to predict linear B-cell epitopes (BCEs) and IEDB server was used for T cells. Then the antigenicity, toxicity, allergenicity were evaluated using bioinformatics tools. After modeling the three-dimensional (3D) structure of the vaccine by Robetta Server, molecular docking and molecular dynamics were performed. Finally, immune simulation and in silico cloning were considered effective for the design of vaccine production strategy.

Results

In total, six epitopes of BCEs, eight epitopes from CD4+ and seven epitopes from CD8+ were selected. The designed multi-epitope vaccine was non-allergenic and non-toxic and showed high levels of antigenicity and immunogenicity. After the 3D structure was predicted, it was refined and validated, which resulted in an optimized model with a Z-score of -7.4. Molecular docking and molecular dynamics simulation of the designed vaccine revealed stable and strong binding interactions. Finally, the results of vaccine immunity simulation showed a significant increase in immunoglobulins, higher levels of IFN-γ and IL-2.

Conclusion

According to the findings, the candidate multi-epitope vaccine has stable structural features. It also has the potential to stimulate long-term immunity in the host, but wet-lab validation is needed to justify it.
Finding ‘Crow’: A case study of the musical setting of recent poetry
Authors: Lancaster Philip
Published: February 2025

One of Ted Hughes’s most remarkable works is one that he never completed; and yet the parts of it that he did publish became one of his most enduring poetry collections: Crow. This book, From the Life and Songs of the Crow, to give it its full title, is a vibrant collection in which the eponymous protagonist appears in multifarious forms, in a multitude of situations; a trickster, exploring the world about it and trying to find meaning and its own place and purpose within that world. In The Laughter of Foxes, Keith Sagar presents a synopsis of what Hughes first intended to be the shape for Crow, a prose narrative within which the songs and poems were to be set. With Crow being so full of its own vigorous poetical music, it is perhaps foolhardy to have even considered trying to set some of the poems to music – an act of butchery, even. Sagar’s expounding of the narrative of Hughes’s unfinished epic lead to the thought of possibly recreating by creative means something of Hughes’s intentions, in the form of a song cycle, drawing on poems from Crow and Cave Birds. The nature of the poetry dictates that this is no lyrically romantic journey, but a more expressionist telling of Crow, with a darkly austere ensemble of just two voices: a ’cello, and a baritone. It is a work in progress at the time of writing, but it has been a long journey to get this far, inhabiting the world of Hughes’s Crow and trying to find ways to express and give life to these extraordinary poems, respecting and honouring the words. This article tells something of the hopes for the project, the process and of some of the thinking behind the work being created.
Silence, sound, rhythm, performance and storytelling: The lyricism of Chile’s Violeta Parra
Authors: De Costa Elena M.
Published: February 2025

Violeta Parra (1917–67) was a Chilean cantora (‘a female singer of the people’), folclorista (‘folklorist’), cantautora (‘singer-songwriter’) and compositora (‘composer’), who promoted and performed rural practices of music, poetry and visual crafts as a portrait of self and a mirror of society. The focus of this article is threefold (1) to analyse Violeta Parra’s translating poetics approach to messaging by exploring her different art forms from sound-text to stage performance; (2) to highlight her significance as a social voice of the working class and Indigenous people as well as the folkloric aspects of her work using both textual and non-verbal modes of vernacular expression and (3) to explore the complementary nature of music, poetry and dance as different languages to represent Parra’s world-view, culture, experience and life in general, as these different artistic expressions inform one another and converge in new perspectives by their messaging format.
El Modelo Multinivel de Contexto: un marco para explorar la manipulación del lenguaje y la manera en que lo mediático y lo político se fusionan en un discurso híbrido
Authors: Berlin Lawrence N. , Brousse Irene
Published: February 2025

Este estudio explora la manipulación del lenguaje en los medios por parte del gobierno para fomentar el dominio y el control, con consecuencias tanto para la ideología pública como para la realidad externa. Para ejemplificar el carácter borroso de las líneas que separan los discursos mediáticos y los discursos políticos a través de la inclusión de mensajes políticos, tanto explícitos como encubiertos, se extraen datos del programa semanal Aló, Presidente, una emisión conducida por el presidente venezolano Hugo Chávez. El período de las transcripciones revisadas incluye diez emisiones desde fines de 2007 hasta principios de 2008, culminando con la crisis política andina en la que el líder bolivariano envió tropas a la frontera con el vecino país, Colombia. Se emplea un análisis crítico del discurso que utiliza el Modelo Multinivel de Contexto (Berlin 2007b, 2011). En la primera parte de la aplicación del marco, se realiza un análisis de opciones (Chouliaraki y Fairclough, 1999) para demostrar cómo el discurso híbrido resultante, aunque exhibe rasgos del discurso político y del mediático, es, de hecho, un orden distinto de discurso que incorpora sus propios y característicos rasgos, incluyendo marcadores de manipulación. En la segunda parte, se recurre a un análisis en cadena (Chouliaraki y Fairclough, 1999) para mostrar cómo la manipulación puede producir efectos más allá de los contextos inmediatos del discurso, y volverse especialmente evidente cuando se la examina a lo largo del tiempo en lugar de hacerlo en un episodio individual del programa.
Resource Analysis in Blockchain Transactions: An Opcode-Driven Multilayer Graph Approach
Authors: Hasnaoui Inas , Zrikem Maria , Elassali Raja
Published: February 2025

Blockchain technology has experienced significant growth across various industries. However, challenges such as scalability, high transaction fees, and resource inefficiencies continue to limit its full potential. This paper presents a novel approach using a multilayer graph to model and analyze blockchain transactions, with a focus on resource consumption—specifically opcode execution and gas usage. By categorizing accounts into distinct layers—Externally Owned Accounts (EOAs), smart contracts, oracles, and cross-chain bridges—the graph-based model captures interactions across these account types. Through transaction trace analysis, we extract opcode usage and gas consumption, applying graph-theoretical metrics such as node scoring and edge weighting to identify critical nodes and resource-intensive transactions. Our findings provide new insights into resource-heavy behaviors, revealing optimization opportunities to reduce transaction costs and improve scalability. Additionally, the approach aids in anomaly detection and smart contract optimization, enhancing the cost-effectiveness and performance of blockchain systems.

Authors:   Transbaikal State University, Chita, Russia, Manikovskiy, P.M.
Published: February 2025

The paper focuses on the production of a material based on ash and slag waste. It could perform the function of a heat insulator during the construction of highways in regions with difficult engineering and geological conditions and geographically located in permafrost distribution areas including insular ones. The study aims to create a material with thermal insulation properties based on ash and slag waste from thermal power plants. The study is experimental in nature and is based on bench modeling of the process of thermal energy transfer through a flat wall. During the study, the authors obtained a mixture based on ash and slag waste from one of the thermal power plants in the south of the Transbaikal Territory. It is considered the optimal composition for creating a material with extremely low thermal conductivity which will undoubtedly have a positive effect in practical implementation as a structural element of a highway. The results obtained during the study can be used in the implementation of the decree of the Government of the Russian Federation dated August 28, 2024 No. 2330-r which comes into force on January 1, 2025.
GEOMETRIC CRITERION OF BEARING CAPACITY LOSS OF STEEL-REINFORCED CONCRETE RODS
Authors:   Nizhny Novgorod State University of Architecture and Civil Engineering, Nizhny Novgorod, Russia, Khazov P.A.
Published: February 2025

The article presents a mathematical model of the deformation process of short steel-concrete rods and a geometric criterion for the loss of bearing capacity. It studies the behavior of steel-concrete elements under the action of a short-term compressive load using laboratory samples made from steel pipes with a concrete core. The article presents the diagrams of longitudinal deformation based on experimental data, as well as an engineering model that makes it possible to obtain the P – Δ dependence for tubular concrete elements by scaling a known diagram for a steel pipe. It al-so estimates the contribution of a concrete core to the operation of a composite section. The article proposes a piecewise monotonically increasing function that analytically describes the deformation of composite rods. It presents a geometric criterion for the loss of bearing capacity with a monotonously increasing deformation curve, which makes it possible to uniquely determine the critical value of the longitudinal force. The result of the research can be incorporated into the algorithm of operation of software and computing complexes used in the automated calculation and design of structures and structural systems.

Published: February 2025

Despite being almost 4000m above sea level, cereal crops have been grown in the Ngari Prefecture on the Tibetan Plateau for thousands of years. Where and when domestic crop species adapted to high-altitude growing conditions is a matter of ongoing debate. Here, the authors present a new radiocarbon date from the Gepa serul cemetery, providing the earliest evidence of naked six-rowed barley in Tibet (c. 3500 BP). Evaluating the available evidence for barley cultivation and interregional connections in central Asia at this time, two hypotheses are considered—a generational advance with farmers migrating up river valleys or rapid, long-distance trade through mountain corridors.

Published: February 2025

In this article, we first obtain, for the Kolmogorov distance, an error bound between a tempered stable and a compound Poisson distribution (CPD) and also an error bound between a tempered stable and an α-stable distribution via Stein’s method. For the smooth Wasserstein distance, an error bound between two tempered stable distributions (TSDs) is also derived. As examples, we discuss the approximation of a TSD to normal and variance-gamma distributions (VGDs). As corollaries, the corresponding limit theorem follows.

Published: February 2025

Neon tetra, Paracheirodon innesi, is endemic to rivers and streams in southeastern Colombia, eastern Peru, and western Brazil and is commercially traded as aquarium fish in the world. In Indonesia, neon tetras were mass produced in Bojongsari District, Depok, West Java as the centre of neon tetra fish production. Understanding their genetic variation is useful for implementing their selective breeding programs, environmental restoration, and estimating genetic contributions in stocks. The current study aimed to investigate the patterns of morphometric and molecular diversity using randomly amplified polymorphic DNA-polymerase chain reaction techniques among farmed broodstocks of P. innesi in Indonesia. Three populations, namely: the Bojongsari, Curug, and Pondok Petir derived from the Bojongsari District, Depok, west Java, were used in the study. Thirty live fish from each location were analyzed based on 25 truss morphometric characters. Sixty fresh fish samples were obtained for DNA analysis using the RAPD-PCR technique, which uses three random primers. Principal component analysis (PCA) was performed to distinguish morphometric variations among populations. Morphological and molecular analysis displayed a similar result that Bojongsari and Pondok Petir neon tetra fish had high similarities, while Curug neon tetra was distinguished from others. The closest genetic distance was between the Pondok Petir and Curug populations (0.4088), while the farthest genetic distance was between the Curug and Bojongsari populations (0.4138). The results will be useful in developing breeding programs to improve broodstock quality.

Стаття присвячена актуальним проблемам ефективності інвестування в умовах ризику та невизначеності, які зумовлені сучасними викликами в економіці України, такими як військові дії, економічна нестабільність, корупційні ризики, зруйнована інфраструктура та нестача капіталу. Розглянуто поняття ризику та невизначеності, їх взаємозв'язок та відмінності, а також вплив на прийняття інвестиційних рішень. Особливу увагу приділено аналізу методів оцінки ризиків, включаючи диверсифікацію, хеджування та партнерство з державою, що дозволяє зменшити негативний вплив невизначеності. Акцентовано увагу на ролі держави у стимулюванні інвестиційної діяльності. Розглянуто значення державно-приватного партнерства, індустріальних парків, а також законодавчих ініціатив, спрямованих на залучення іноземних та внутрішніх інвесторів. Зазначено, що індустріальні парки виступають місцем для швидкого старту бізнесу за рахунок наявної інфраструктури діяльності та спрощеним умовам ведення.
Приділено увагу викликам для інвесторів в умовах воєнного стану, включаючи зростання військових ризиків, економічну нестабільність, стійкість у доступі до фінансування, правову невизначеність та відтік робочої сили. Автори відзначають значний потенціал України як інвестиційного майданчика за критеріями її стратегічного розташування, природних ресурсів, технологічних можливостей та активізації реформ, спрямованих на покращення інвестиційного клімату.

Innovations in the Family Legislation of the Russian Federation: Analysis of the Legislative Initiatives and Law Enforcement Trends
Authors: Osadchenko Elvira
Published: February 2025

Introduction: the transformation and evolution of modern society, its values, and its priorities are simultaneously evidenced in fairly sustainable and stable social institutions, which include family and marriage. The multifaceted issues of demography, the family, the transmission of the cultural code, and spiritual heritage through generations currently occupy a central place in state policy – the year of 2024 has been declared the year of the family in Russia. The Russian legislator is carefully and delicately introducing changes in family law, dictated by established judicial practice and aimed at consolidating positive trends (in particular, the protection of paternity as part of alimony obligations), avoiding radical innovations (such as, for example, the introduction of the right to freedom of gender/sexual self-determination). At the same time, the events taking place in the country and disturbing the usual way of life are a powerful factor affecting the family and social condition. The purpose of the study is to identify the reaction of the legislator and law enforcer to the paradigmatic transformation of family and marital relations. Methods: the methodological framework for the study is a set of methods of scientific cognition, whose main ones are analysis, synthesis, generalization, and comparative jurisprudence. Results: the current state of the institution of marriage is characterized by the formation of a new type of family and the construction of new models of marriage, which entails the need to modernize the established legal foundations in this area, whose outline we can observe in the scientifically based concepts and supported by various state development programs. We can observe innovations in marital relations both in the proposed legislative initiatives and in the emerging judicial practice. Conclusions: in modern realities, the law enforcer is faced with such negative phenomena as sham marriages, putative marriages, and putative termination of marital relations, where the parties determine their sociolegal status based on material interest, without pursuing goals arising from the nature of marital relations. According to the author, the legislative initiative on the recognition of actually existing marital relations in a judicial application procedure at the request of one of the parties is aimed at undermining the basic principle of marriage – the mutual expressed consent of both persons wishing to marry. The transformations considered in the marriage sphere allow believing that the special military operation has also played an important role in this process, which has changed the views of many people on the meaning of marriage and its key principles.
Genetic Testing as a Comprehensive Service: The Sources and Content of the Legal Regulation
Authors: Kryukova Elena , Inyushkin Alexey
Published: February 2025

Introduction: the successful conduct of genetic research has allowed moving towards the introduction of individual approaches to the prevention, diagnosis, and treatment of diseases. The widespread use of innovations, in turn, has required proper legal support for genetic testing, which is the basis of personalized medicine focused on the genetic characteristics of the patient. Despite the obvious benefits, the active dissemination of the designated medical service is associated with a number of diverse problems and risks, whose effective elimination is facilitated by a comprehensive and coordinated approach to building the legal regulation. Methods: the methodological framework for the work is made up of both the general scientific and specific scientific research methods. Results: the analysis of the concept and species diversity of genetic testing has allowed substantiating the complex nature of the service under study, identifying the interdependence of testing and medical genetic counseling (both preliminary and subsequent), and tracing a close connection with the legal regime of the genetic information obtained during its implementation. The paper determines that the specifics of this procedure require its isolation in the system of medical services in terms of the legal regulation. Expanded regulation will make it possible to clearly and in detail establish the conditions, restrictions, implementation procedure, and stages of its provision, including subsequent routing for the patient. This approach will make it possible to ensure the quality of the service, distribute the areas of responsibility of its performers, and create additional guarantees for the protection of genetic information. Conclusions: as a result of the study, it is concluded that it is necessary to build a multi-level system for regulating the “genetic testing” service, within which it is proposed to fix the fundamental provisions in the basic sectoral law, the parties, conditions, and algorithm of provision in a separate special law, and the features of some types may be reflected in the departmental acts accompanying certain areas and spheres of medical care activities. The complex nature of the service will determine the content of the legal regulation. The issue of the fate of the information additionally identified during testing that is not related to the original purpose of providing the service is subject to the regulatory resolution.
