Published: March 2023

Lung Cancer is a dangerous disease which is caused by consumption of tobacco and other pollutants it is very hard to predict. But in this era of technology, prediction of lung cancer is possible with the help of machine learning and deep learning algorithms. According to the surveys the survival rate of patients that are affected by cancer is very low, it is because of lack of prediction of cancerous cells in earlier phase. In this Project we use CT(Computed Tomography) scan images of malignant, benign and normal cases are taken in the dataset to classify them as cancerous and non-cancerous images with the help of CNN family Algorithm, i.e, Inception V3 Algorithm. The CT scan images are preprocessed with the help of image preprocessing techniques such as image warping and image cropping. After the preprocessing of the CT images the images are processed with Inception V3 Algorithm, the image dataset is trained under Inception V3 Algorithm of deep learning technique and under the range of 10 epochs the best accuracy the algorithm has provided is 97%. Many Machine Learning Algorithms are used to classify the images such as SVM, CNN, etc. But under deep learning technique the inception V3 algorithm has provided the best accuracy so far. Keywords— CT Scan Images, CNN Algorithm, Cancer Nodules, Malignant cases, Benign Cases, Normal Cases, Inception V3 Algorithm, SVM Algorithm, Image Warping and Image Cropping.

Published: March 2023

This paper analyzes seasonal dynamics of the Mongun-Taiga massif vegetation cover from February to October 2022 based on the application of the NDVI vegetation index using Sentinel-2 satellite imagery data. To analyze the seasonal dynamics of the vegetation index of the Mongun-Taiga massif, 15 points on the valleys of five rivers were selected they are the Tolaity River (south side), the Holash River (west side), the Balyktyg River (north side), the Right-Mugur River (north-east side) and the Shara-Khoragai river (east side). The graphs of the vegetation cover of different exposures of the massif slopes show that the highest values are represented at the western side of the massif (the Holash River), then on the southern side (the Tolaity River) and then on the northern side of the massif (the Balyktyg River). The valleys of the Shara-Khoragai River (east side) and the Right-Mugur River (north-east side) have the lowest indicators of vegetation cover. Different curves of the vegetation cover graphs for different exposures of the massif explain that the climate in this area is very complex. Terrain, slope exposures, humidity, strength and direction of winds, sunlight, temperature, slopes of selected points, as well as watercourses affect vegetation cover differently. For a more thorough study, it is necessary to obtain higher-resolution images and conduct ground-based measurement work to assess the state of the vegetation cover of the massif and obtain accurate meteorological data.

Published: March 2023

The paper presents the results of the study of temperature regime optimization for storing seeds of tropical orchids on the example of Eulophia streptopetala Lindley and Stanhopea tigrina Batem ex Lindl. Mature seeds were frozen at temperatures of 18C, 40C or 80C for a period of 1, 3, 6 or 12 months, the storage temperature was +4C. Before and after freezing, the viability of seeds was determined by visual and tetrazole methods. After defrosting, the seeds were sown and the plants grown from them were cultivated on a nutrient asymmetric medium, then the dynamics of plant development was recorded, the content of photosynthesis pigments (chlorophyll and carotenoids) was quantified. The analysis of the data obtained showed that the viability of seeds significantly decreases after storage, including in conditions of low temperatures. At the same time, in experimental groups of plants, the terms of early ontogenetic states were shortened, and the growth rate of protocorms increased. Freezing of seeds caused further restructuring of the photosynthetic apparatus. The optimal temperatures for storing seeds of the species Eulophia streptopetala were +4C, and for Stanhopea tigrina 80C and 40C.
Vegetation and biotopes of the regional botanical natural monument «Kashtak Pine Forest» (Sosnovskiy District of Chelyabinsk Oblast)
Authors: Nazarenko Nazar Nikolayevich
Published: March 2023

The vegetation and biotopes of the regional botanical natural monument Kashtak Pine Forest have been characterized in this paper. By multivariate statistics and a dominant approach 13 pine and birch-pine plant associations have been identified. But in most cases the associations are detected by dominance or co-dominance of Fragaria vesca L. in the herbage in spite of high biodiversity. The difference of associations is identified by shrub species dominance mainly. The biotopes of the regional botanical natural monument Kashtak Pine Forest are not characterized by principal abiotic factors of high variation while the differences are determined by coenotic factors. The classification of Kashtak Pine Forest biotopes is identified by soil acidity and soil nitrogen regimes in the first place. For Kashtak Pine Forest three ordination axes have been detected: 1) boreal pine forests of Boreal zone, 2) temperate pine and birch-pine forests of Temperate Forest and Forest-Steppe zones and 3) axe of soil moistening and cryoregime. Three coenotic series have also been detected: hydrosere of Fragaria vesca associations and two trophoseries of boreal pine forests of Boreal zone. These series form an integrated biotopical sere and succession of South-Urals pine forests from temperate forest-steppe pine forests to boreal pine forests of Boreal zone.

The total contents of Mn, Cr, Ni, Cu, Zn, Pb and Cd in foreshore soils and bottom sediments of 20 ponds have been investigated for the first time in Samara by the method of spectrometry with inductively coupled plasma. It is shown that polymetallic pollution of coastal soils and bottom sediments of 16 ponds out of 20 considered is acceptable; 3 ponds, located in the 13th microdistrict (small pond) and on the Solnechnaya street (large and small ponds), are characterized by moderately hazardous pollution with heavy metals; 1 pond, located in the area of the former Hippodrome, has a high level of pollution of coastal soils. Cu, Zn and Pb should be considered to be the main elements that significantly affected the ecological state of coastal soils and bottom sediments of the studied ponds. Their content in selected samples ranged: from 0,3 to 20,3 for Cu, from 0,2 to 14,9 units for Zn, from 0,2 to 25,2 units of background concentrations to Pb. The analysis of heavy metals average levels in coastal soils and bottom sediments of Samara ponds showed, that bottom sediments were enriched with all analyzed metals except Mn in comparison with coastal soils, whereas Mn was accumulated to upper levels in coastal soils. The location of water bodies in various parts of the urban area relief caused differences between the levels of heavy metals accumulation. For instance, the coastal soils of the ponds located on the watershed between the Saratov reservoir and the Samara River accumulated heavy metals more actively than the coastal soils of the ponds on the Volga slope. The accumulation of heavy metals in bottom sediments on the watershed was more active for Mn, Cr, Zn and Cd whereas in the ponds on the Volga slope it was shown for Ni, Cu and Pb.

The world population growth postulates a necessity for food increase to provide mankind with edible products. A growing number of archaeobotanical finds of acorns indicates that they were important as a staple food for some regions. According to its characteristics, red oak is one of the promising species that can increase the resource potential of oak forests in the Middle Volga region. Compared to local oak one, red oak wood is more resistant to vascular and necrotic-cancerous pathologies. The red oak is also more resistant to oak powdery mildew. On the territory of the Middle Volga region, red oak is still rare, because of its limited use in plantations. The subject of the study is the quality of red oak seeds formed by trees from the arboretum of the Institute of Ecology of the Volga Basin (Togliatti city), where they were collected in an amount enough to assess the quality of seeds formed by an introduced species on a territory new to it. The study of the internal structure of oak seeds with dense shells was carried out by digital microfocus radiography using a PRDU installation. This method is included in international standards, primarily for assessing the formation of the seeds internal structure and grain damage by phytophages. X-ray screening allowed to categorize the red oak seeds: 1) seeds, fully formed, filled and not damaged by insects; 2) seeds that, when falling from a tree, retain their cupula (do not have a developed content); 3) seeds damaged by insects during the formation of cotyledons; 4) seeds without a cupula, but with varying severity of underdevelopment; 5) seeds with partial underdevelopment of the cotyledons, which do not fill the entire volume of the seed coats. The weight and size parameters of seeds formed in the Samara region correspond to the indicators from other regions of red oak growth and are: diameter 1,76 0,01 cm; length 2,48 0,02 cm; weight of 1000 seeds 4224 62,65 g (harvest 2021). At the same time, only from 55 to 39% of red oak seeds (harvests in 2021 and 2022, respectively) were of a sufficiently high quality to be used for sowing. Considering the prospects of red oak as an agent of biological invasion, the authors point to the variability of its seed harvest by years, the formation of a high proportion of low-quality seeds, as well as a small amount of self-seedings with increased demands to soil moisture.
Sex identification of Humboldt penguins using a morphometric analysis
Authors: Sabutskaya Miroslava Alekseevna
Published: March 2023

Primorsky Aquarium keeps a population of 32 Humboldt penguins. The employees of Ornithology Department are faced with a problem of sex identification of 18 immature/young penguins. Male and female Humboldt penguins have not significant differences in feather coloration, so reliable sex identification by direct observation is not possible. The most reliable ultrasound and genetic methods require special equipment, reagents and qualified specialists as well as provoke stress that is dangerous for the health of the birds. Sex identification by morphometric parameters for captivity birds is more preferable, since this procedure is non-invasive, does not require special equipment and specialists. We have performed a statistical analysis of measurements of the beak length in 3 variations, of the dorsal part of flipper length, and weight of females and males of the studied group. For the first time, we have added to the analysis the length of the beak from the nostril, which was not previously taken into account. It has been found that the use of 4 traits simultaneously in the analysis does not demonstrate a significant correlation with the sex of the bird, and therefore is not suitable for the sex identification of penguins. The most consistent features for correlation analysis were the beak length and the flipper length. The maximum grouping of birds by sex within the study group was observed while comparing these morphometric characteristics.

Published: March 2023

The widespread use of triazoles in agriculture as retardants has led to the need to investigate the possible mutagenic effects of these compounds on natural ecosystems adjacent to agrocoenoses. Model experiments were set up to investigate the ability to induce dominant lethal mutations by synthesized triazoles: 1,2,4-triazole: (1,2,4-triazole (1,2,4-TrH), N-triazolid methanesulfonic acid (CH₃SO₂TrH), N-triazolid benzene sulfonic acid (PhSO₂1,2,4-Tr) and N-triazolid toluene sulfonic acid (4-CH₃ ArSO₂1,2,4-Tr) in Drosophila melanogaster adults. The possibility of developing an adaptive response to these compounds in Drosophila melanogaster was studied. A relationship between the structure and physicochemical properties of the studied alkyl(aryl)sulfonyl 1,2,4-triazoles and their mutagenicity was analyzed. A series was constructed in which mutagenicity for Drosophila adults decreases in the following order: CH₃SO₂TrH 1,2,4-TrH PhSO₂1,2,4-TrH 4-CH₃ArSO₂1,2,4-TrH, both when exposed to non-toxic doses of substances (0,001 mg/ml concentration) and when exposed to compounds at a dose of LD₅₀. It has been established that a short-term (within a day) preliminary action on adults by nontoxic doses (0,0001 mg/ml) followed by action on the same adults by these substances in LD₅₀ dose causes an adaptive response only in females of Drosophila melanogaster. Long-term exposure (the entire larval life period of drosophila) to a nontoxic dose and then repeated exposure of the same Drosophila melanogaster adults to the same compounds at the LD₅₀ dose caused a significant decrease in the number of induced dominant lethalities in females as well as in drosophila males. Consequently, the adaptive response developed only in tissues with an active cell division. It is supposed that the repair mechanisms leading to the development of an adaptive response in adults and larvae are different.
The influence of the Sayano-Shushenskaya Dam reservoir on the nesting and abundance of the osprey (Pandion haliaetus L., 1758)
Authors: Shikalova Elena Alekseevna
Published: March 2023

The paper presents the materials of the study of the osprey grouping on the territory of the Sayano-Shushensky Nature Reserve. Before the formation of the reservoir, 34 osprey nests were recorded on the banks of the Yenisei. The flooding of the valley was accompanied by the formation of extensive flat areas suitable for nesting. The volume of fish resources that form the basis of the ospreys food supply has increased and their availability is one of the main criteria of the ecosystem, on which the number of this rare bird depends. Continuous monitoring of the osprey grouping on the shores of the Sayano-Shushenskaya Dam reservoir within the Sayano-Shushensky Nature Reserve began in 2012. The work included a survey of suitable habitats in order to identify nesting sites, certification of nests, accounting of adult birds, as well as monitoring the reproduction of ospreys. Based on the results of the research, it was possible to create a model of optimal natural conditions for nesting ospreys in the mountainous regions of Siberia. The creation of a large artificial reservoir has had a positive impact on the number of protected groups of ospreys. A special regime of strict protection peculiar to biosphere reserves plays a positive role, which excludes visits to nest bays, significantly reducing the anxiety factor. Together, this allows the birds to expand the nesting areas and breed offspring.

Published: March 2023

The trends of the coenoflora structure dynamics of the perennial grass crops communities were characterized on the gradient of restorative succession in the conditions of the steppe and forest-steppe zones of the Southern Urals. Using an agglomerative cluster analysis, four community groups have been identified, which corresponds to the stages of succession and reflecting the age of the communities (from 1 to 16 years or more). It is demonstrated that the succession gradient complicates the species composition, the species richness of the communities increases by almost 2 times. An analysis of the activity index change for the coenoflora core species at each stage has been carried out. It has been revealed that the activity of sown herbs species decreases, while the total activity of well-eaten species as well as the feed value of the whole phytocoenoses increases with the age of communities. A community of each stage of succession is marked by a group of highly active species, the functional composition and coenotic affinity of which changes. The activity of apophyte species increases while the activity of synanthropic ones decreases. There is a natural complication of the phytosociological spectrum from species of affine to classes of synanthropic vegetation Sisymbrietea and Artemisietea to species of classes of natural vegetation meadows (Molinio-Arrhenatheretea) and steppes (Festuco-Brometea). At the same time, the most active substitution of synanthropic species for natural ones occurs after the second stage of succession, i.e. its significant acceleration is observed after the age of 11 years. According to the results of the ordination analysis (DCA-ordination) with an additional assessment of the contribution of environmental variables, the leading in the differentiation of the species composition of communities is the factor of the age of communities, the factor of humidification of habitats makes a smaller contribution. According to the results of the comparison of the studied phytocoenoses with the data of weed, meadow and steppe communities from the database of non-forest vegetation of the Southern Urals (1660 releves), the central position of perennial grass crop communities on the gradient of restorative succession from disturbed arable land vegetation to natural (steppes) (steppes) and quasi-natural (meadows) vegetation types is demonstrated. Thus, a high importance of perennial grass crops for the creation of stable phytocoenoses of high forage value, which can be used for the restoration of biodiversity in the forest-steppe and steppe regions, is revealed.

Published: March 2023

The paper is devoted to the results of the research materials of Kairshak site of the North Caspian Sea region. The relevance of the topic is determined by the role of this region in the Neolithic process of Eastern Europe. The ceramic tradition of the early Neolithic is one of the oldest in this region. Technical and technological analysis of ceramics indicates that the dishes were made of silt with an addition of freshwater molluscs. Different vessels are typologically identified. An ornament is made by a drawn line and a single prick. The set of features allows to assign the collection of ceramics to the Kairshak type. Stone tools are characterized by plate-flake technique. End scrapers dominated. Arrowed and other forms are rarely met. The second category concludes geometrical microliths of segment type. The number of sharp points isnt big. An amount of indicators indicates that the complex has an early Neolithic character. A kind of animal is identified with an archeozoological method kulan. The radiocarbon date indicates the end of the 6th millennium BC. This contradicts the available data bank on the chronology of the Kairshak type sites. According to all characteristics of the stone and ceramic inventory, the discovered complex is most similar to the materials of the Kairshak I.

Published: March 2023

The study of the USA cinema during World War II is interesting not only from the point of view of forming the image of the enemy, but also of allies. This will allow us to determine more accurately what visual propaganda techniques were used by American directors. The image of China was always significant for the American information discourse: through it they created and adjusted of ideas about the East as an arena of struggle between the USA and Japan. This paper reveals features of the process of mythologizing the Second World War in the American cinema in 19411942, through an analysis of the features of constructing the image of China in the USA films. This will make it possible to judge the cinematography of the war years as a special phenomenon of the socio-political and cultural life of the United States of America. In addition, the features of American films about China, the methods and techniques of propaganda, and the role of cinema in the overall system of the American propaganda are clarified. The features of the process of visualization and mythologization of the Second World War in American society are determined as a historical phenomenon of the public life of the United States of America, which reflects both general (characteristic of civilization as a whole) and national patterns. The authors study interethnic imagological plots (the image of enemies and allies on the screen) as well as internal ones (American volunteers, the image of America), which have no less strong influence on the formation of the American national self-concept in a historical crisis period.
Anti-communism as a factor in shaping the foreign policy of the Russian Federation in 1991–1992
Authors: Mochalov Dmitriy Petrovich , Magomedov Ramazan Radzhabovich
Published: March 2023

The purpose of the paper is to consider the anti-communist component in the foreign policy of the Russian Federation during the first post-Soviet years. Based on the material of the socio-political periodicals of that time and the documents of the archive of the Presidential Center of Boris Yeltsin, the influence of the struggle against the threat of communist revenge inside the country on the foreign policy of the state is traced. The paper examines the international reaction to the persecution of the Communist Party in Russia and attempts to use this event to promote foreign policy interests. The specific steps of the Russian leadership in the fight against the international communist movement and the assessment of this activity by contemporaries are considered. Various conceptual approaches to overcoming the Soviet in the field of international relations, which were formulated in Russia at that time, are highlighted. The main directions of using anti-communist rhetoric in building relations with a number of states, successes and failures in this direction are outlined. The conclusion is made about the preservation of the ideological component in the Russian foreign policy of the first post-Soviet years, despite the declarations on the de-ideologization of this sphere. It is noted that the anti-communism of the new government has not always been an effective tool in achieving foreign policy goals and has not always found a positive assessment even in Western countries.
The Soviet military-industrial complex in 1945–1950: crisis or conversion transition (historiographical aspect)
Authors: Zakharchenko Aleksey Vladimirovich
Published: March 2023

The paper presents an analysis of the historiography of the military-industrial complex development in the USSR in 19451950. Attention is focused on determining the main approaches to the development of the military-industrial complex in the years of post-war economic recovery. The results of the study show that the characterization of the situation in which military production found itself since the second half of 1945, as a crisis, has no sufficient grounds. Most of the problems experienced by the Soviet military-industrial complex took place during the Great Patriotic War and even earlier. The transition to a peaceful life only aggravated them. Changes in the military-industrial complex system after the war were not related to the crisis, but to the conversion transition, which was accompanied by significant investments in new industries rocket science, nuclear industry, radar. On the other hand, the conversion process was characterized by an increase in the share of civilian output and a reduction in defence products. Modern Russian historiography shows that the approach to managing the economy of military production and planning underwent changes. The requirements for the quality of weapons in connection with the increase in their service life became tougher. It is proved that one of the promising directions in historiography at the present stage is the plot of interdepartmental conflicts in the military-industrial complex system and ways to resolve them.

Authors: Kremneva Alena Sergeevna , Markova Nadezhda Grigorievna , Kudasheva Alexandra Alekseevna
Published: March 2023

In this paper the authors actualize the need for the development of moral qualities and feelings among students with signs of giftedness, which encourage them to overcome difficulties, solve educational problems of various designs. The moral paradigm in the organization of an individual educational route of students with signs of giftedness is the basis of constructive subjective interaction. Namely, the development of moral qualities helps each student to build his or her own individual educational route. The purposefulness and systematic nature of pedagogical influences in the organization of an individual educational route of students helps to consolidate their moral qualities, develop moral feelings, and most importantly, develop skills and habits of moral behavior that are necessary for the implementation of an individual educational route. Students with signs of giftedness gradually develop confidence, willpower, and an active lifestyle. Practice confirms that the purposefulness and systematic impact on the consciousness and feelings of students makes it possible to maintain the productive educational process, oriented on the development of the students personality, the consolidation of his qualities and the enrichment of motivation resources. The development of students personal qualities affects the quality of the individual educational route of students with signs of giftedness, their creative activity in general, the formation of an active life position and the formation of studying habits.
The hermeneutic approach for shaping students’ experience of moral interaction with other people
Authors: Razumovskaya Anna Aleksandrovna
Published: March 2023

The paper actualizes the problem of preparing young people studying in vocational education institutions for moral interaction with other people, one of the aspects of which is the shaping of students experience of moral interaction as a personal education with a structure (cognitive, motivational-value, communicative and behavioral components). The potential of hermeneutic, value, dialogic and personal-activity approaches in shaping the experience of students moral interaction with other people is substantiated, and the advantage of each of the approaches to the shaping of a specific component of experience is indicated. The possibilities of the hermeneutic approach, the central concept of which is understanding, are revealed in the shaping of the cognitive component of the experience of students moral interaction. The correlation of knowledge and understanding is substantiated: knowledge, which precedes understanding and serves as its source, is presented to the individual in various forms, the main of which is the text. The potential of the hermeneutic arc is revealed in equipping students with knowledge that shapes the content of the cognitive component of the experience of moral interaction between students: knowledge about morality, values, etc., known to students, is enriched through the content of the texts presented to them, acquiring personal meaning, and then, returning to the life of students, substantiates their choice of ways of moral interaction. It is proved that the implementation of the hermeneutic approach contributes to the isolation in the texts presented to the student of such knowledge that justifies the students choice of ways of moral interaction, provides a reflective comprehension by the student of another person based on a deep personal understanding.

The paper discusses the types and features of school expeditions and their role in the meta-subject approach of teaching schoolchildren. An expedition is an off-site event that is conducted according to a developed program in order to learn and study the territory and/or several objects. Depending on the goals and objectives, research, educational, historical and local history school expeditions are distinguished. An educational expedition is understood as an extensive, well-designed event organized by teachers of various subjects to consolidate the knowledge of students acquired at school, to acquire skills to solve various problems in society. The educational expedition can be used both in regular and extracurricular activities in order to implement a meta-subject approach in teaching schoolchildren. Since 2021, the educational project Interesting lessons in sneakers has been implemented in Secondary School № 14 of Novocheboksarsk of the Chuvash Republic. A program, a scenario, didactic materials, feedback questionnaires are compiled for each educational expedition, and the necessary documents are prepared for the organization and holding of the event. Within the framework of the project, 6 field educational expeditions were conducted with a total coverage of more than 160 people: Time to fly, In the footsteps of Robinson Crusoe, Sursky Frontier, A visit to the marmots, Tsvetik-semitsvetik, BBK. Conducting educational expeditions increases the natural science functional literacy of students, develops cognitive and research skills.
Philosophical prerequisites for researching the personal and developmental potential of knowledge of the prospective engineer
Authors: Charikova Irina Nikolaevna
Published: March 2023

Changes taking place in the dynamically developing industrial production and society determine the key resource and wealth of the information society knowledge, meanings, ideas, educational design and creativity of the subject of engineering activity. The problem of the personal development potential of knowledge as the most important attribution that becomes in the space of professional self-development of the prospective engineer is relevant for modern society. Today, the need for innovative transformations in the training of engineers of a new formation with the appropriate amount of knowledge for the successful solution of scientific, technical and production-organizational problems is obvious. The idea of coevolution of natural and social epistemically manifests itself in modern bionic engineering projects, awakening professional education to investigate the phenomenon of interpenetration of knowledge and mechanisms of cognition. The paper attempted to assess the existing aspects of the problem under consideration, to justify the relevance of the appeal to philosophical and scientific knowledge, the teaching of knowledge, the fundamental provisions of which will provide the required result, both for professional and personal development of prospective engineers. To determine the philosophical prerequisites for the personal-developing potential of knowledge, we turned to epistemology, a science that is more occupied with the value-meaning question: What is knowledge for a person? What matters more in the development of personality as a subject of cognition? The study has found that in the changed conditions of modern information and communicative civilization, epistemology puts forward the requirement to rethink traditional ideas about knowledge, how to obtain it and justify it. Its task-target functionality includes understanding the categorical essence of knowledge, identifying the grounds for its reliability, considering the mechanisms and models of cognitive processes; search for prerequisites for the developing potential of knowledge; awareness of the world around us, and the opportunities to live and act in it.

Published: March 2023

Due to their starting and running torque needs as well as their four-quadrant operation, modern industrial drives utilise induction motors (IM). Failures in the rotor bars of the motor can be found using the voltages and currents of each of the three phases as well as the acceleration and velocity signals. For the diagnosis of the quantity of broken rotor bars for a failed IM, conventional signal processing-based feature extraction techniques and machine learning algorithms have been applied in the past. The number of broken rotor bars is determined in this study by looking into a novel technique. For the aforementioned aims, specifically, the deep learning methodologies are studied. In order to do this, convolutional neural network (CNN) transfer learning algorithms are described. Initially, a bandpass filter is used for denoising, and then the signals are transformed using the continuous wavelet transform to create time-frequency pictures (CWT). The collected images are used for deep feature extraction and classification using the support vector machine (SVM) classifier, as well as for fine-tuning the pre-trained ResNet18 model. Metrics for performance evaluation employ categorization accuracy. Additionally, the results demonstrate that the deep features that are recovered from the mechanical vibration signal and current signal yield the greatest accuracy score of 100%. Nonetheless, a performance comparison with the publicly available techniques is also done. The comparisons also demonstrate that the proposed strategy outperforms the compared methods in terms of accuracy scores.

Specific Antibody Deficiency
Authors: Petrak Russell
Published: March 2023

Patients with recurrent infections generate a large number of outpatient infectious disease referrals. While the differential diagnosis is vast, primary immunodeficiency is a consideration, but frequently overlooked. A subset of these maladies is Specific Antibody Deficiency. By definition, this diagnosis requires levels of both quantitative immunoglobulins and IgG subsets to be normal. Therapy is available, making identification of this immunodeficiency critical.
On the Minimization Problem of the Sum of Ratios
Authors: Jargalsaikhan Davaajargal , Darkhijav Bayarjargal
Published: March 2023

We consider the problem of minimizing a sums of ratios that belong to a class of global optimization problems. Since the problem is nonconvex, the application of local search algorithms cannot always guarantee to find a global solution. It has been shown that problem can be solved by DC programming methods and algorithms. Dinkelbach-type algorithms are more efficient techniques because fractional problems reduce to a scalarized optimization problem. For solving the problem, we apply a generalized Dinkelbach algorithm requires finding the roots of a nonlinear equation. The numerical experiments were conducted on Python Jupyter Notebook for a box constrained set. The problem also has been solved by a gradient descent method and compared with the Dinkelbach algorithm. Numerical results are provided.

Artificial Neural Network Method for Solving of Bratu’s Problem
Authors: Badarch Tumurkhuyag , Balt Batgerel
Published: March 2023

The Bratu’s problem is widely used to model phenomenas such as heat transfer and combustion theory. For certain values of the parameters, there are 2 different solutions,  and finding the lower solution is not difficult, and it is quite possible to apply standard  mathematical methods for it calculation. However, finding the upper solution is difficult and requires the use of high-order convergent algorithms. In this study, the method of calculating the numerical solution of the Bratu’s problem using artificial neural networks is considered.  When constructing the neural network, sinusoids were used as the activation function, and RMSprop (Root Mean Squared Propagation) was used as the optimization method. By doing so, its possible to calculate two solutions of the Bratu’s problem.   

Хиймэл Нейроны Сүлжээг Ашиглан Нэг Хэмжээст Брату Бодлогын Шийдийг Тооцоолох нь

Хураангуй: Брату бодлогыг дулаан дамжуулалт, шаталтын процесс гэх мэт үзэгдлүүдийг загварчлахад өргөн ашигладаг. Тэгшитгэл параметрийн тодорхой утгуудад хоёр шийдтэй бөгөөд доод шийдийг олох нь төвөггүй, тооцон бодох математикийн стандарт аргуудыг хэрэглэх бүрэн боломжтой. Харин дээд шийдийг олох нь бэрхшээлтэй бөгөөд өндөр эрэмбийн нийлэлттэй алгоритмуудыг ашиглах шаардлага тулгардаг. Энэхүү судалгаанд Брату бодлогын тоон ший- дийг хиймэл нейроны сүлжээ ашиглан тооцоолох аргыг авч үзлээ. Нейроны сүлжээг байгуулахдаа идэвхжилтийн функцээр синусоидийг, оновчлолын аргаар RMSprop (Root Mean Squared Propagation) аргыг ашиглав. Ингэснээр Брату бодлогын хоёр шийдийг тооцоолох боломжтой болов.

Study on Interactions of the SARS-CoV-2 Spike Proteins with the Human Toll-like Receptor 4 using Molecular Dynamic Simulations
Authors: Chagdarjav Munkhdalai , Balt Batgerel , Mijiddorj Batsaikhan
Published: March 2023

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) has speared around the world since December 2019.  SARS-CoV-2 induces the human innate and adaptive immune systems, and the activation pathways are not still fully understood. However, several studies have shown that interaction between the S1 subunit of SARS-CoV-2 spike proteins and human toll-like receptor 4 (hTLR4)  activates the innate immune responses. It leads to the cytokines over secretions and may facilitate the ‘cytokines storm’ that contributes to the severity of the COVID-19 patients.  However, the atomic-level explanation of the interaction between spike proteins and hTLR4 has not yet been elucidated. In this study, we performed molecular dynamics simulations of spike protein and hTLR4 to clarify their interaction. We show the possible interactions of spike protein and hTLR4.   

SARS-CoV-2 Вирусийн Спайк Уураг ба Хүний Толл-төст Рецептор 4 Уураг хоорондын Харилцан Үйлчлэлийн Молекулын Динамик Симуляци

Хураангуй: COVID-19 өвчний үүсгэгч SARS-CoV-2 вирус нь 2019 оны 12 сараас эхлэн дэлхий  даяар тархаад байна. SARS-CoV-2 вирус нь төрөлхийн болон өвөрмөц дархлааны системийг  идэвхжүүлдэг ба идэвхжүүлэх зам одоо ч бүрэн ойлгогдоогүй байна. Сүүлийн үеийн судалгаагаар SARS-CoV-2 вирусийн спайк уураг нь хүний толл-төст рецептор 4 уурагтай харилцан  үйлчлэх замаар төрөлхийн дархлааны хариу үйлдлийг өдөөж, олон төрлийн цитокинуудын хэт  их нийлэгжлийг идэвхжүүлдэг болохыг харуулсан. Цитокинуудын хэт их нийлэгжил нь COVID-19-тэй өвчтөний хүндрэлийн зэргийг нэмэгдүүлдэг. Гэсэн хэдий ч спайк уураг болон хүний TLR4  уураг хоорондын харилцан үйлчлэлийн талаар атомын түвшинд нарийн тайлбарлаагүй байна.  Энэ ажлаар SARS-CoV-2 вирусийн спайк уураг ба хүний TLR4 уураг хоорондын харилцан  үйлчлэлийг молекулын динамик симуляцийн аргаар судлав. Симуляциар SARS-CoV-2 вирусийн спайк уургийн ялгаатай хоёр гинжний амин төгсгөлийн домеин ба рецепторт холбогдогч  домеин хамтарч хүний TLR4 уурагтай холбогдож болохыг харуулав. Энэ үр дүн SARS-CoV-2  вирусийн спайк уураг болон хүний TLR4 уураг хоорондын харилцан үйлчлэлийн механизмыг  ойлгоход чухал мэдээлэл болно.
