Reorganization of the National Network of Mass Libraries: From the History of the State Library Policy of the 20th Century
Authors:   Altai State Institute of Culture, Fomina Anna
Published: December 2022

The centralization of libraries in the works of domestic experts has received an ambiguous assessment. The experience of the zemstvo system, the development of network construction by mass libraries were negatively interpreted for ideological reasons. A negative assessment of the work on the creation of a unified library network in the pre-war period prevented its development. It took decades for the party-state leadership to revise the criticism of the idea of centralization. During the second half of the 20th century, the centralization of library management structures was supplemented by technologies of interlibrary interaction. The introduction by mass libraries of standards for the bibliographic description of documents, the systematization of funds based on domestic tables of library and bibliographic classification allowed to join the work of interlibrary subscription, depository storage of funds.

Immune checkpoint inhibitors are monoclonal antibodies directed against the molecules blocking immune response, such as cytotoxic T-lymphocyte- associated protein 4 (CTLA-4), programmed cell death protein-1 (PD1) and its ligand, which enhance anti-tumor immunity. Immune checkpoint inhibitors have demonstrated high efficacy in cancer treatment, including the most common types of cancer and helped to increase recurrence- free and overall survival of cancer patients. At the same time, the use of checkpoint inhibitors is associated with a high risk of immune-related adverse events (irAEs) — autoimmune conditions that occur in multiple organs and tissues, including endocrinopathies. Endocrine irAEs can affect the thyroid, pituitary gland, adrenal glands, and pancreas. These events are unique when compared with other irAEs because the manifestations are often irreversible. The awareness of clinicians of potential irAEs, including endocrinopathies caused by agents from the group of immune checkpoint inhibitors will improve their timely identification and treatment. Thus, it will promote the safe use of highly effective anti-tumor therapy.

Can Dimensional Anisotropy Satisfy Mach's Principle? A Topological Approach to Variable Dimensions of Space using the Borsuk-Ulam Theorem
Authors: Deli Eva
Published: December 2022

In general relativity, Einstein's equations relate the geometry of space-time to the distribution of matter. Nevertheless, the equations are in contradiction with quantum mechanics and even possibly our experience of physical reality. We propose a thought experiment to investigate a compact wave function (WF) insulated by an information-blocking horizon. The WF can produce entanglement independent of distance, but interaction with the horizon evolves the quantum state (frequency) and the topology (curvature) of the horizon in an orthogonal relationship. Their mutual evolution satisfies the Borsuk-Ulam Theorem and the Page and Wootters mechanism of static time. Therefore, the field curvature measures the particle's evolution as time and fine-tunes the cosmos' parameters. The interaction of the field and the compact WF give rise to poles with dimensionality transformations, and it formulates global self-regulation. Because field strength generates pressure, culminating in two-dimensional black hole horizons (infinite time), whereas vacuum gives rise to four-dimensional cosmic voids (time zero). The four-dimensional cosmic voids can produce accelerating expansion without dark energy on the one hand, and pressure gives the impression of dark matter on the other. The verifiable and elegant hypothesis satisfies Mach's principle.
Honorary Authorship in Biomedical Journals: The Endless Story
Authors: Kandil Mohamed
Published: December 2022

Honorary authorship is when a scientist has been listed as a co-author without significant contribution to the manuscript. Although unethical, honorary authorship is on the rise. The motive behind it is different for scientists at different stages of their career. It helps juniors to get more publications and thereby have faster promotions and probably better employment opportunities. For scientists more advanced in their careers, it helps getting more scientific recognition and possible financial gains. Honorary authorship is not without disadvantages. It is probably held responsible for the over inflation in the number of authors per article in different publications. On the individual level, it dilutes the contribution of each author and may ruin the reputation of an honorary author if the data integrity were found questionable after publication.

This work studied the impact of graphene content and heat treatment on the structural changes and electrical parameters of graphite/N-doped graphene mixtures. Using photoelectron spectroscopy the appearance of two types of carbon-containing phases was detected in the visible range of the N-doped graphene samples synthesized from liquid nitrogen. The following features of the samples were shown: one typical structure of graphene (sp2C–sp2C), two atypical structures (sp3C–N and the C–O bond), and graphene components modified with nitrogen (pyridine–N, pyrrole–N, graphite–N and oxidized N–O). The dependence between the ratio of components in graphite–graphene mixtures and their electrochemical properties was found. The effect of graphite content and heat treatment on the change in the type of conductivity in a graphite–graphene mixture was determined by comparison of resistance and capacitance distribution in the frequency range of 100–900 Hz. The change of the graphite concentration in the graphene–graphite mixture allows governing the type of doping and electrical parameters of the mixtures.

This paper considers the principles of designing a composite mixture for the production of ceramic facing bricks based on clay materials. The complex of conducted researches allows establishing rational technological parameters of molding and firing of ceramic products to achieve high values of operational properties. Composite charges were obtained based on clays from Druzhkovsky and Zalyutinsky deposits, as well as on clay wastes of zircon-ilmenite sand enrichment from Vilnohirsk Mining and Metallurgical Plant. It was established that based on these materials by forming via the method of rigid extrusion and application of firing at temperatures of 1020–10400С, it is possible to fabricate a ceramic brick of grade not lower than M225.
Comparison of measured resistance for drilled shafts socketed in weak rock in Oklahoma to previously established SPT and TCP-based predictive design relations
Authors:   , Burton Elgin
Published: December 2022

The design of drilled shafts socketed in shale and other weak rock is challenging for a multitude of reasons. Sites may be difficult to characterize because the materials may quickly degrade upon sampling. The materials can also be highly variable on not only a site-specific basis, but on regional and even global scales as well. Shale and other weak rock also pose challenges for purely empirical calibrations because of the relative strength of these materials -- it is often difficult to achieve ultimate failure in load tests and as a result, many available field load test measurements are not completely suitable for calibration of resistance factors. Furthermore, the performance of drilled shafts in shale and other weak rock may be greatly affected by construction techniques which are difficult to account for in design. Due to the difficulties posed by shale and other weak rock, numerous alternative design methods based on in situ testing have been proposed and used (e.g. TCP, SPT, pressuremeter, point load index test, etc.); however the reliability of these methods is often unquantified or poorly characterized. Fortunately, more consistent reliability can be achieved by developing and adopting resistance factors that are taken to be a function of the variability and uncertainty for design input parameters. Currently, design of bridge foundations for transportation infrastructure in the U.S. is performed following LRFD methods; however ODOT does not presently employ such a design method. Therefore, the motivation of the works described herein is to facilitate and inform the development of rational and defensible methods for design of drilled shafts in weak rock based on previous experience developing design methods for federal and state transportation agencies. Eight drilled shafts were constructed to support the development of methods for the load and resistance factor design of drilled shafts in weak rock. Four drilled shafts with 4-foot diameters and 70-foot lengths were constructed in Minco, Oklahoma targeting the Fairmont Shale formations. Four more drilled shafts with 4-foot diameters and 45-foot lengths were constructed in Edmond, Oklahoma targeting the Garber Sandstone formation. All test shafts were loaded with a bi-directional load cell, the Osterberg Cell (O-CellTM), to establish ultimate unit tip and ultimate unit side resistance values. The results of the load tests were compared to previously established SPT and TCP-based predictive design relations to facilitate and inform the development of an Oklahoma-specific load and resistance factor design method with the expectation that this developed method would produce a more economical drilled shaft foundation design for use by the Oklahoma Department of Transportation while fulfilling established target reliabilities.

Cytoprotection and neural regeneration in peripheral nerve injury
Authors:   , Dahlgren Kylie Joy
Published: December 2022

Neural injuries are some of the most common ailments presented in the clinic, affecting up to 20 million Americans. While a number of treatments have been studied, many of their drawbacks outweigh their advantages, so new solutions are still needed. Simple signaling molecules (SSMs), very small agents that govern bioactivity, offer an exciting approach to traditional approaches due to their small size, availability, and influence on cellular pathways. In this research, I evaluated the cytoprotective and neuroinductive capacity of three SSMs: hydrogen sulfide (H2S), n-acetyl cysteine (NAC), and glutathione (GSH). To investigate each molecule's cytoprotective effect, neural stem cells (NE-4Cs) were exposed to a toxic level of a known reactive oxygen species (ROS) - hydrogen peroxide (H2O2) - while supplemented with various concentrations of H2S, NAC, or GSH. In this model of oxidative stress, H2S did not exhibit significant cytoprotective effects, however, NAC and GSH both demonstrated considerable promise. In specific, therapeutic ranges of 2 - 8 mM NAC and 2 - 12 mM GSH were established as cytoprotective against H2O2-mediated cellular insult. To study the neuroinductivity of H2S, NAC, and GSH in NE-4Cs, immunofluorescence microscopy for an early neuronal marker, [beta]3 tubulin, was employed to assess stem cell neural differentiation. This evaluation revealed that H2S presented the most neuroinductive potential, while NAC and GSH showed little capacity to facilitate neuronal differentiation. A neuroinductive window of 3.9 - 250 [mu]M H2S was established through this study. With the neuroinductive range of H2S and the cytoprotective ranges of NAC and GSH identified, this research paves the way for future controlled drug delivery systems of these molecules to be developed and implemented for peripheral nerve injury applications.
Neotectonic assessment of the southern Wassuk Range, western Nevada
Authors:   , Heins Julie
Published: December 2022

Active deformation across western North America is distributed across a broad zone spanning from the San Andreas fault system to the Basin and Range Province. The Wassuk Range fault zone (WRFZ), located within the Walker Lane deformation belt of the western Basin and Range, is a N- to NNW-striking normal fault system. With its oblique orientation to the wide-scale, NW-trending shear between Pacific and North American plates, it demonstrates a transtensional regime. The Whiskey Flat study area (southern WRFZ) corresponds with east-dipping, late Quaternary fault scarps ([tilde] 1-7 meters) along the range front. Seismic and photogrammetric methods were used to examine underlying geometry and fault scarp morphology. Through these imaging techniques, fault scarp degradation modeling assessed the kinematic evolution and longterm slip rate of [tilde] 0.10-0.36 mm/yr, accommodating 0.49-1.4 mm/yr of E-W extension. Significantly, this extension rate is slightly faster than northern and central segments of the Wassuk Range. Holocene earthquakes are estimated to have occurred between 687 and 3774 years ago with magnitudes that range from 6.9 to 7.1. In addition, seismic refraction imaging reveals a potential asymmetric half-graben formation, supporting the idea of a dominant normal fault system that aligns with the broad, NW-trending, rightlateral shear of the Walker Lane and associating plate boundaries. This study demonstrates how structural evolution, neotectonic activity, and future deformation can be gleaned from seismic imaging techniques and numerical models of landscape morphology.
Migrations of love and circumstance: a history of intimacy and policy in the migration of Italian war brides, 1943-1954
Authors:   , Limmer Michael Bird
Published: December 2022

In the spring of 1946, the foreign brides and children of American soldiers from the Second World War migrated to the United States through mass migrations coordinated by the War Department. This project contextualizes the lives of Italian war brides in regards to twentieth-century migration through their experiences in Italy, within American immigration policy, and their lives after immigration to America. War brides emerged from the mass global deployment of the American G.I.s through an array of coercive and consensual social-sexual encounters abroad. The Allied Military Government, Congress, and the War Department sought to control their interactions in the war-torn and inequal sexual economy of Italy, but their efforts had limited effect. Propaganda depicted Italian women in paradoxical imaginaries, but much to the dismay of overseeing institutions, these soldiers and foreign women married and had sexual relations. After the war, the restrictions and bureaucracy of the immigration system that inhibited immigration frustrated soldiers, their foreign wives, and in-laws. This required Congress to reckon with their competing desires to uphold restriction while doing everything for the soldier. This led to the facilitation and privileged immigration of war brides that established conjugal love and heteronormativity within the quota system. In America, war brides, tied to their soldier husbands, experienced an isolating migration experience away from ethnicity and towards domesticity. The complicated origins of immigration and the context of war shaped a new kind of migration around war bride identity that was anchored in a new kind of domestic assimilation that erased their migrant identities and migration experience.
E-scooter simulator development and applications
Authors:   , Qi Weitong
Published: December 2022

Although electric scooters have brought a lot of convenience to people's lives, the laws and regulations related to it are just being developed, and the number of people injured by electric scooters is increasing every year. Most of the published literature on electric scooters is from a safety perspective, while this research is more from the perspective of people's riding behavior. To better understanding people's riding behavior, the ZouSim E-Scooter simulator was built. The design process of the simulator can be divided into two parts, hardware development and software development. The hardware development includes the construction of the simulator base and the applications of the measurement sensors. The software development includes the use of Arduino for data collection and transmission, and the use of Unity3D for scenario creating. Due to the COVID-19 epidemic, this research only includes 25 human subjects, and all subjects experienced the same scenarios to ensure the validity of the data. The collected data shows that when the subjects were not educated, 60 percent of them chose to ride on the sidewalk. After being educated, only 3 percent of them chose to ride on the sidewalk. This shows that electric scooter education is effective on most riders. Upon the completion of the test, each subject was given a post-simulation survey. From the survey results, 76 percent of the human subjects admitted that they had never worn a helmet when riding an electric scooter, and only 8 percent of the test subjects said that they always wear a helmet when riding an electric scooter. Moreover, 56 percent of the test subjects said that even though they knew that riding on the sidewalk might have potential risks to pedestrians, they still preferred to ride on the sidewalk because they were uncomfortable with riding on the street next to vehicles. Policy makers could consider this preference in formulating rules and policies instead of regulating E-Scooters solely because they are motorized.
Effects of beta radiation on nanostructured semiconductor devices for low energy radiation sensing
Authors:   , Acosta Eric Milan
Published: December 2022

Beta radiation detection currently relies primarily on scintillation detectors. However, the construction of these detectors tends to be large which significantly limits their applicability for field-use. A nanostructured Pt/TiO2/Ti Schottky device was constructed for use as a compact, low energy radiation detector by making use of surface plasmon resonance which has been shown to enhance energy coupling in similar technologies. The fabrication of the device was done by first electrochemically anodizing a titanium substrate to create a nanoporous surface, followed by annealing to produce a crystalline, semiconducting TiO2 layer and finally the deposition of the Pt Schottky metal through atomic layer deposition. Modeling of the device using COMSOL software showed the formation of strong electric fields when nanostructures were present. Exposure of the device to low energy 63Ni beta radiation showed a 2-to-3-fold increase to the forward current during radiation exposure without any additional signal amplification. This increase in the current is a consequence of a 2 to 4 percent lowering of the Schottky barrier height during radiation exposure as well as the production of hot and secondary electrons in the semiconductor. Subsequent improvements to the device using rapid thermal annealing resulted in a nearly 6 percent decrease of the Schottky barrier height during radiation exposure and a consequent 5-fold increase to the forward bias current in the presence of radiation. Thus, in its current construction the device is capable of being used as a qualitative low energy beta radiation detector.
Moving object localization using frequency measurements
Authors:   , Ahmed Musaab Mohammed
Published: December 2022

This research investigates the ability of locating a moving object using the Doppler shifts of a carrier frequency signal sent or re ected by the object and observed by several fixed or moving sensors spatially distributed in the 2-D or 3-D space. The idea was previously studied and several solutions are proposed based on exhaustive grid search or numerical polynomial optimization. We shall formulate the problem as a constrained optimization and propose two efficient solutions. The first is by using linear optimization method to reach a closed-form solution and the second is through semi-definite relaxation technique to achieve a noise resilient estimate. The solutions are derived first for the single-time measurement and then developed to multipletime observations collected during a short time interval in which the object motion is linear. Several scenarios are considered including 2-D and 3-D localization geometry, the sensors are fixed or moving along nonlinear trajectory with random speed, the presence of errors in the carrier frequency and the sensor positions, and the noncooperative object scenario where the frequency of the carrier signal is completely not known. Analysis validates the algebraic closed-form solution in reaching the Cramer- Rao Lower Bound accuracy under Gaussian noise within the small error region. The simulations show good performance for the proposed algorithms and support the theoretical analysis.
Applied genomics toward targeted improvement of soybean
Authors:   , Dietz Nicholas Andrew
Published: December 2022

The abundance of genomic data produced by the research community in the last decade has offered an unprecedented view into the variation present in the soybean genome and has been exploited to uncover the genetic architecture of important agronomic traits. In this work, I utilized resequence and genetic marker data to show the geographic distribution of natural variation in the E1La gene and that it likely played a major role in migration of wild soybean to higher latitudes. I further demonstrated that this variant allele could be utilized to promote maturity in both an e1-as and E1 background. An induced mutation of the E1Lb gene also promoted maturity, although its effect was only observed in an e1-as background. By pooling together resequenced accessions from several published works, I developed a catalogue containing an allele for every gene in the genome of [greater than] 1000 soybean accessions. Using latitude of origination as a proxy for relative flowering time, I tested [greater than] 100 soybean orthologues of Arabidopsis flowering genes for their allele distribution among the subset of US cultivars in this catalogue and identified eight candidate genes likely playing a role in reproductive timing of US soybean. I also used this resource to compare the allele composition of these US cultivars to 16 of the major North American ancestor lines from which they are derived. From this analysis, I highlighted regions of the genome which have experienced artificial selection during US breeding efforts and found that over 60 percent of genes are fixed or nearly fixed for a single allele. Taken together, these data will facilitate breeder selection for appropriate maturity in their programs and define a framework for identifying regions of genetic variation and fixation in their germplasm.
Molecular approaches to improve soybean plant architecture and seed composition
Authors:   , Kim Jeonghwa
Published: December 2022

Soybean is an important agronomic crop which has been widely used as a vegetable oil as well as a source of protein for animals and humans. Among various desired traits for genetic improvement to improve the value of soybean, yield and seed composition deserve attention considering its ever-increasing demand as well as where its overall value comes from. In terms of yield improvement, the current research suggested an alternative strategy to remodel the architecture of soybean plants for better adaptation, especially to high yield environments. From the field trials in three latitudinal environments in the US, tall determinate soybean types were found to change the overall plant architecture of soybean in both Midwest and Southern environments in the US by increasing plant height and node number and creating similar stem thickness and pod density at the stem tip compared to typical determinate types. The increase in pod-bearing nodes with lodging resistance has the potential to result in more yield, especially in high yield planting environments. Further agronomic merits need to be examined in diverse environments for its full utilization in soybean breeding. For the improvement of soybean seed composition, this research showed the feasibility of soybean variety development with an oil and meal value bundle. The results from eight environments indicated that the desired oil, the high oleic and low linolenic acid oil trait (HOLL; [greater than] 70 percent oleic and [less than] 3 percent linolenic acid), and meal value traits, the reduced seed content of the raffinose family of oligosaccharides (RFO), can be successfully combined by genotype selection without interference. The modified seed composition traits will contribute to creating healthier, more oxidatively stable soybean oil and higher metabolizable energy soybean meal.
Privacy-preserving collaboration in an integrated social environment
Authors:   , Uplavikar Nitish Milind
Published: December 2022

Privacy and security of data have been a critical concern at the state, organization and individual levels since times immemorial. New and innovative methods for data storage, retrieval and analysis have given rise to greater challenges on these fronts. Online social networks (OSNs) are at the forefront of individual privacy concerns due to their ubiquity, popularity and possession of a large collection of users' personal data. These OSNs use recommender systems along with their integration partners (IPs) for offering an enriching user experience and growth. However, the recommender systems provided by these OSNs inadvertently leak private user information. In this work, we develop solutions targeted at addressing existing, real-world privacy issues for recommender systems that are deployed across multiple OSNs. Specifically, we identify the various ways through which privacy leaks can occur in a friend recommendation system (FRS), and propose a comprehensive solution that integrates both Differential Privacy and Secure Multi-Party Computation (MPC) to provide a holistic privacy guarantee. We model a privacy-preserving similarity computation framework and library named Lucene-P2. It includes the efficient privacy-preserving Latent Semantic Indexing (LSI) extension. OSNs can use the Lucene-P2 framework to evaluate similarity scores for their private inputs without sharing them. Security proofs are provided under semi-honest and malicious adversary models. We analyze the computation and communication complexities of the protocols proposed and empirically test them on real-world datasets. These solutions provide functional efficiency and data utility for practical applications to an extent.

Authors:   , Yao Shizeng
Published: December 2022

Multi-view stereopsis (MVS) is a core problem in computer vision, which takes a set of scene views together with known camera poses, then produces a geometric representation of the underlying 3D model Using 3D reconstruction one can determine any object's 3D profile, as well as knowing the 3D coordinate of any point on the profile. The 3D reconstruction of objects is a generally scientific problem and core technology of a wide variety of fields, such as Computer Aided Geometric Design (CAGD), computer graphics, computer animation, computer vision, medical imaging, computational science, virtual reality, digital media, etc. However, though MVS problems have been studied for decades, many challenges still exist in current state-of-the-art algorithms, for example, many algorithms still lack accuracy and completeness when tested on city-scale large datasets, most MVS algorithms available require a large amount of execution time and/or specialized hardware and software, which results in high cost, and etc... This dissertation work tries to address all the challenges we mentioned, and proposed multiple solutions. More specifically, this dissertation work proposed multiple novel MVS algorithms to automatically and accurately reconstruct the underlying 3D scenes. By proposing a novel volumetric voxel-based method, one of our algorithms achieved near real-time runtime speed, which does not require any special hardware or software, and can be deployed onto power-constrained embedded systems. By developing a new camera clustering module and a novel weighted voting-based surface likelihood estimation module, our algorithm is generalized to process di erent datasets, and achieved the best performance in terms of accuracy and completeness when compared with existing algorithms. This dissertation work also performs the very first quantitative evaluation in terms of precision, recall, and F-score using real-world LiDAR groundtruth data. Last but not least, this dissertation work proposes an automatic workflow, which can stitch multiple point cloud models with limited overlapping areas into one larger 3D model for better geographical coverage. All the results presented in this dissertation work have been evaluated in our wide area motion imagery (WAMI) dataset, and improved the state-of-the-art performances by a large margin.The generated results from this dissertation work have been successfully used in many aspects, including: city digitization, improving detection and tracking performances, real time dynamic shadow detection, 3D change detection, visibility map generating, VR environment, and visualization combined with other information, such as building footprint and roads.

The increasing population growth, the more vehicle users. This makes the government also have toimprove transportation services. One way is to improve the quality of asphalt in order to meet its servicelife. But the problem that is happening at this time is the difficulty of getting rock ash filler where in therules it is stated that fine aggregate (fly ash) must pass sieve no. 200 under 10%. This research mixed flyash as much as 1%, 2%, and 3%. The results of the study are the addition of fly ash from burning coalash as a filler for combustion residue from the Tanjung Enim PLTU for Asphalt Concrete WearingCourse (AC WC) asphalt mixture, the best results were obtained on a 2% mixture with the followingvalues: Stability value of 1240, 253 kg, VIM (Void In Mix) Value of 4.233%, VMA (Void in MineralAggregate) Value of 16.139%, VFB (Void Filled Bitumen) Value of 73.782%, Flow (melting) Value of3.63 mm and Marshall Quotient obtained at 329.280 kg/mm.

Geopolymer is the synthesis of inorganic natural materials through a polymerization process. The mainingredients in the manufacture of geopolymers are materials containing silica and alumina. Geopolymermaterial can be obtained from coal industry waste products such as fly ash. Innovative technology inmanufacturing foam concrete is widely used in building construction, such as using earthquake-resistantbuilding walls and energy-efficient buildings. In this study, geopolymer foam concrete was manufacturedby combining a mixture of geopolymer and a mixture of foam. A solution of 14 M NaOH and Na2SiO3with a ratio of 2.5 was used as an activator. Fly ash is a precursor, and the ratio of foaming agent andwater is 1:20, 1:30, and 1:40, which is used as a material for making foam. This study aimed todetermine geopolymer foam concrete's physical and mechanical properties with various foaming agentsand water. The results of testing for air content in fresh concrete indicate that the use of more foamingagents in the manufacture of foam can improve the quality of the foam and reduce the air content of theconcrete so that it can increase the compressive strength of the test object. The use of fewer foamingagents can reduce the density of geopolymer foam concrete.

Background: Dermatophytes are keratinophilic fungi that affect the stratum corneum of the skin and keratinous structures. Violent factors play a vital role in the pathogenesis and antifungal resistance of dermatophytes. Objective: This study aims to evaluate the activity of extracellular enzymatic and biofilm formation as virulence factors of dermatophyte isolates. Methods: Fifty-eight dermatophyte isolates belonged to 27 Trichophyton. rubrum (46.6%), 19 T. mentagrophytes (32.8%), and 12 Microsporum. canis (20.7%) for evaluating the activity of phospholipase, hemolysin, proteinase, and biofilm formation were examined. The biofilm formed was analyzed by scanning electron microscopy (SEM). Findings: Evaluation of extracellular enzymes production revealed that 86.2%, 77.6 %, and 57% of dermatophyte strains were shown to be phospholipase, hemolysin, and proteinase producers, respectively. Furthermore, all isolates of T. rubrum and M. canis can produce phospholipase and hemolysin, respectively. There was a statistically significant difference between phospholipase activity and dermatophyte strains (P<0.05). In addition, biofilm formation ability was observed in 41.5% of dermatophyte isolates. The highest level of biofilm production was found in 93% of dermatophytes isolated from nail chips. A significant difference between biofilm formation with dermatophyte isolates and different body sites was observed (P <0.05). Conclusion: The activity of hydrolytic enzymes and biofilm formation as important pathogenic factors may play a role in the persistence of dermatophytosis infections. Our results showed that dermatophyte isolates have enzymatic activity and biofilm production at different levels. Therefore, understanding the function of these factors is essential to controlling the spread of dermatophytosis infection.
“Human – Social Robot” Interaction: Through Overcoming Barriers to Hybrid Communication

Published: December 2022

Introduction. The article analyzes the problems that arise during communication between a person and a social robot. Barriers that prevent a person from adapting to the specifics of communication tools embedded in the software of devices with artificial intelligence are revealed. Human reactions to the behavior of humanoid robots in various conditions of their use are analyzed. The presence of a person's desire to adapt to the behavior pattern of the device is checked. The authors also test the hypothesis of the emergence of hybrid communication as a way to overcome the barriers of human communication with smart devices. 

Methodology and sources.The approach implemented in the article interprets the communication of a person and a social robot as a similar subject-subject interaction of performers of social roles by heterogeneous communication participants who implement a model of mutual adaptation to the reactions of the Other. As the key methods there was used the method of observation, mediated by digital recordings of human communication situations with various types of devices. A nonobtrusive (unobtrusive) research method was applied, which excludes the contact of the researcher with the object of study. The sources were audiovisual documents containing recordings of a demonstration of human communication with a social robot.

Results and discussion.A weak orientation of a person to adjust his reactions to actions on the part of a social robot with simultaneous attempts to modify his behavior with a focus on imitation of the robot was revealed. The development of hybrid reactions is affected by an increase in the duration of human communication with the device. To a greater extent, hybrid forms of communication continue to be present in the software embedded in social robots of its communication with a person.

Conclusion. In the process of reproducing the stable nature of communication in the peculiarities of the behavior of each of the parties, there were ways of responding to overcome the blockade, not foreseen either by the developers of the algorithms or by a person entering into communication with a robot with the expectation of programmed “machine behavior”. Such a process remains predominantly one-sided and is not supplemented by the activity of the other party – a person, their participation in the synthesis of natural and artificial languages, which is impossible without modification of the language of the person oneself, and their cultural and bodily modifications.
