New genetic tools for plant defense against parasitic nematodes
Authors: Kochetov A. V. , Gavrilenko T. A. , Afanasenko O. S.
Published: June 2021

Nematodes belong to economically important pests. Here we reviewed the recent data on molecular mechanisms of plant resistance to cyst and gall nematodes including the most devastating Globodera rostochiensis, G. pallida, Heterodera schachtii, Meloidogyne chitwoodi, and M. incognita. The Golden Potato Cyst Nematode (G. rostochiensis, GPCN) may be taken as an example of an economically important pest: in Russia, it occurs in 61 regions with a total area of 1.8 million ha and may cause the yield loss from 19 to 90 %. The biological characteristics of sedentary nematodes makes their agrotechnical control problematic, i.e. the GPCN cysts remain dormant in soil for many years until a susceptible host appears, whereas nematicides are either toxic or inefficient. Introgression of resistance genes (R-genes) from related cultivated or wild species is likely to be the most appropriate way for their biocontrol. The life cycle of sedentary nematodes is based on juveniles’ penetration into the host root where they reprogram plant cells into a syncytium or the so-called ‘giant cells’ and inhibit the plant defense response. Molecular mechanisms of plant-nematode interaction are unusual and this phenomenon provides a very interesting model for the investigation of plant morphogenesis control as well as for the development of new genetic instruments of biocontrol. Here we reviewed recent publications on plant parasitic nematode effectors used for hijacking of the plant immune system, data on R-genes and molecular mechanisms of their activities. In addition, host-induced gene silencing (HIGS) is discussed as a perspective mechanism for nematode biocontrol. HIGS is based on the RNA interference in the cells of the host plant addressed against the nematode genes important for their development and productivity. Several recent investigations demonstrated efficiency of HIGS against sedentary nematodes.
A Case of Blue Nevus of the Nasal Septum
Authors: Choi Jun Yong , Choi Myoung Su
Published: June 2021

Blue nevus (BN) is a blue- or black-colored benign melanocytic proliferation that commonly occurs on the dorsal surface of the hands and feet or in the head and neck region. However, BN arising from the sinonasal mucosa is extremely rare. BN is usually asymptomatic and small in size. Based on the pigmentation of BN, sinonasal malignant melanoma should be considered in the differential diagnosis of BNs in this region. We herein report a case of BN of the nasal septum. Histopathologic examination revealed the presence of heavily pigmented, spindle-shaped melanocytic cells within the stromal tissue. On immunohistochemical analysis, BN cells were positive for S-100 and HMB-45. Due to the few reported cases of sinonasal BN and challenging location, complete resection, biopsy, and adequate follow-up are recommended.
Complications After Inadequate Treatment of Nasal Bone Fracture Combined With Septal Fracture: A Case Report
Authors: Yang Seung Koo , Hong Seung-No
Published: June 2021

In treating a nasal bone, an incomplete nasal bone reduction can result in nasal deformity, both aesthetic and functional, requiring a secondary operation. A 60-year-old female with a traumatic comminuted nasal bone fracture with septal fracture was initially treated with closed reduction, which later resulted in a saddle nose and a completely occluded nasal cavity. Later, the patient underwent a revision operation of extracorporeal septorhinoplasty with rib cartilage graft, and the postoperative course was uneventful. Herein, we present a case of complications occurring after inadequate treatment of septal fracture. Physicians should thoroughly evaluate the extent of the nasal bone fracture, including the integrity of the nasal septum, and manage accordingly.
Taxation and Customs Reforms in Fragile States: Between Bargaining and Enforcement
Authors: Cantens Thomas , Raballand Gaël
Published: June 2021

In the last decade, African authorities and the international community have called for support to increase taxation capacity in order to reduce reliance on aid flows. This commitment to support tax administrations was reflected in the 2015 Addis Tax Initiative (ATI), which advocated ‘to double assistance to developing countries in order to strengthen their tax systems and administrations’ by the year 2020 (IMF 2017: 6). Increasing domestic resource mobilisation is even more salient for state-building in fragile states, in terms of providing costly services to citizens, including security, across national territory. There is a rich literature (Acemoglu and Robinson 2012; Besley and Persson 2009) arguing that robust and inclusive fiscal institutions are essential for state-building and economic growth. This is not the situation in fragile states.
Access to Climate Finance by Women and Marginalised Groups in the Global South
Authors: Price Roz
Published: June 2021

This paper examines the issue of management of climate finance in the Global South. It acknowledges the efforts made by the various stakeholders so far but seeks to advance a clarion call for a more inclusive and targeted approach in dealing with climate change. The authors highlight the limited role played by least developed countries and small island developing states in contributing to the conversation on climate change. The authors emphasize the need for enhancing the role of the most vulnerable countries, marginalized groups, and indigenous peoples in the management of climate change. This rapid review focusses on the access to the Green Climate Fund by local civil society organisations (CSOs), indigenous peoples, and women organizations within the Global South. The authors observe that there still exist barriers to climate finance by local actors in the Global South. The authors note the need for more significant engagement of all local actors and the need to devolve climate finance to the lowest level possible to the most vulnerable groups. Particularly, climate finance should take into consideration gender equality in any mitigation measures. The paper also highlights the benefits of engaging CSOs in the engagement of climate finance. The paper argues that local actors have the potential to deliver more targeted, context-relevant, and appropriate climate adaptation outcomes. This can be attributed to the growing movement for locally-led adaptation, a new paradigm where decisions over how, when, and where to adapt are led by communities and local actors. There is also a need to build capacities and strengthen institutions and organisations. Further, it is important to ensure transparency and equitable use and allocation of climate finance by all players.
Key Considerations: Operational Considerations for Building Community Resilience for COVID-19 Response and Recovery
Authors: Schmidt-Sane Megan , Niederberger Eva , Hrynick Tabitha
Published: June 2021

As the unequal impact of the COVID-19 pandemic continues, there is a need to robustly support vulnerable communities and bolster ‘community resilience.’ A community resilience approach means to work in partnership with communities and strengthen their capacities to mitigate the impact of the pandemic, including its social and economic fallout. However, this is not resilience which returns the status quo. This moment demands transformative change in which inequalities are tackled and socioeconomic conditions are improved. While a community resilience approach is relatively new to epidemic preparedness and response, it frames epidemic shocks more holistically and from the perspective of a whole system. While epidemic response often focuses on mitigating vulnerabilities, there is an opportunity to use a resilience framework to build existing capacities to manage health, social, psychosocial, and economic impacts of an epidemic. This makes a resilience approach more localised, adaptable, and sustainable in the long-term, which are key tenets of an epidemic response informed by social science. This brief presents considerations for how health and humanitarian practitioners can support communities to respond to and recover from COVID-19 using a community resilience approach. This brief was developed for SSHAP by IDS (led by Megan Schmidt-Sane with Tabitha Hrynick) with Anthrologica (Eva Niederberger).
«Charlatans from medicine» in the «times of great tribulation» in the works of Lu Sin, A. Chekhov, M. Zoshchenko and V. Shalamov»
Authors:   Southwest university in Chongqing, Boldyreva Elena M.
Published: June 2021

The article is devoted to the analysis of the specifics of the artistic representation of the image of the doctorcharlatan in the stories of A. Chekhov, M. Zoshchenko, Lu Sin and V. Shalamov. The article demonstrates that in the humorous stories of A. Chekhov and M. Zoshchenko the phenomenon of «charlatans from medicine» is presented in an ironic mode, when writers create many comic, farcical and vaudeville plots, in which illiterate doctors try to treat stupid common patients unsuccessfully; in the works of Lu Sin and V. Shalamov, this topic is presented in a fundamentally different way: they express the tragedy of a person who has become a hostage of political and social upheavals. Theauthors distinguish three main plot invariants in the medical discourse of writers: plots in which the motive of «drug» is realized – a pseudo-drug used by charlatans for treatment (from farcical and comically absurd in the works of Chekhov and Zoshchenko to senselessly inhuman, associated with motives of blood and death in the works of Shalamov and Lu Sin), plots in which the motive of «the executioner and the victim» is presented, accentuating the barbaric and sadistic methods of treatment used by «charlatans from medicine» and plots where the subject of the image becomes the emotional deprivation of a doctor or pseudo-doctor, a kind of «anesthesia of the heart «, presented in a comic version by Zoshchenko and Chekhov and in a tragic version by Shalamov and Lu Sin. The author comes to the conclusion that doctors M. Zoshchenko and A. Chekhov, in their executioner incarnation, are so naively simple-minded that they are not frightening, but comical and perform their «unconscious butchery» without malicious intent, or out of fear to admit their professional incompetence, or being absolutely sure of their own infallibility, and sick victims lose their martyr's halo, they are equated with doctors in terms of the narrowness of their horizons, and therefore their suffering causes not compassion and sympathy, but laughter. The charlatan healers of Lu Sin embody the tragic hypostasis of butchery, perceiving their healing «torture by fire and blood» as loyalty to barbaric ancient traditions and mythological customs, Shalamov's doctors are sophisticated sadists, their deliberate butchery is based on the awareness of the inviolability of their sacred status, the victims are not treated, but exposed, so they perceive their torment and suffering outside the ethical paradigm and feel their butchery as a creative act, receiving aesthetic pleasure from the process of «medical butchering» and from the awareness of their chosenness and the right to decide human destinies.

Published: June 2021

The phenomenon of multiethnic groups is becoming an urgent issue at the university level. An increased number of mixed groups of learners from different cultures highlights the lack of appropriate methods and means of planning the educational process and requires developing a newer scientific understanding of the education individualization as a strategy for training specialists at the pedagogical university. This paper deals with the theoretical foundations of the individualization in students training in the multiethnic group. The authors have set the objectives of studying the passport of the current national project «Education» by the Russian government; of analyzing the theoretical foundations of multicultural education; of developing some new principles which are to complete the author's concept of individualization of professional training of students at the pedagogical university; of describing the culture maps as a means of individualization of education within multiethnic groups. The authors come to the conclusion that even general understanding of students’ culture-specific behaviours in the educational environment, made into the culture map for each individual multiethnic university group of the university,can help to promote mutual understanding between the subjects of the educational process, which is a factor of the outer individualization. Besides, it can help students accurately understand the professional goals of their training at a Russian pedagogical university, and motivate students to develop an active social attitudes, which is a factor of the inner individualization of training. The authors emphasise the important role of the culture-specific factors in the process of individualization of professional training of students in the multiethnic group of a pedagogical university. The results obtained in the paper can be used in education in order to increase the attractiveness and competitiveness of the Russian universities in the international education industry.

Published: June 2021

A study of subjective safety, its determinants, strategies and psychological mechanisms is very urgent at the present time. There is the theoretical research that is devoted to consideration of the issue of a leading factor in the dyad «the safety – personality features» in this article. On the one hand, personality features determine the characteristics of the safety state, on the other hand, the safety state determines occurrence of personal features. The personal safety is seen as a mental state. The article shows that the safety has all features of mental states. The research was conducted with reliance on age development concepts and mental states concepts. The article presents that personality features are primary and they determine occurrence and particular qualities of the safety state from the perspective of authors of mental states concepts. Authors of age development concepts approve a great part of safe environment in childhood for successful development of a child and for psychological well-being of an adult. From this viewpoint, the safety determines occurrence of personality features. The article shows that mechanism of formation of tendency to the safety state is similar to the process of interiorization as conversion of the external safety (the safety of environment) to the internal (personal) safety. Interiorization of the safety occurs in childhood. The authors of the article take into consideration the stability of personal traits in adulthood and suggest that in adulthood leading factor in the dyad «the safety – personality features» is personality features. Safety need is a basic motivational factor thatinfluences mental life, behavior and activity of human. The safety state and personality features influence together human’s behavior and activity. One of the tasks of the further research is to study the problem empirically. Such examination has theoretical and practical significance. Results of the research may be used in child psychology, advisory psychology, family psychology, military psychology and in other branches of psychology
Relationship between indicators of communication, self-esteem and interpersonal status of preschool children
Authors:   Vitebsk state university named after P. M. Masherov, Lautkina Svetlana V. , Selezneva Irina N. ,   Vitebsk regional institute for education development
Published: June 2021

Communication, complex multidimensional education, begins its active development directly in preschool age. With the correct and timely development of communication, cognitive processes, emotional-volitional and motivational-need spheres, behavior, and the interpersonal status of the child are formed. The formation of communication skills is possible only with the timely full development of speech. The lower the state of speech, the more difficult it is for the child to organize and implement communication, and vice versa, the higher the level of formation of the communicative act, the more fully expressive speech develops. Difficulties in forming speech and communication affect self-esteem. Self-esteem as a phenomenon develops under the influence of the assessment of others. Self-esteem is the result of one's own activity, communication, behavior, activities, experiences of a preschooler. The inability of a preschooler to implement verbal communication in a peer group leads to deformations in the development of personality and interpersonal interaction, reduces his social status, and leads to his isolation from other members of the team. Summarizing the above, we have set a goal – to study the relationship between indicators of communication, selfesteem and interpersonal status in preschool children. The main research method is the contrast group method. Empirical study was carried out in groups of preschoolers – with normal speech development and with speech disorders («General speech underdevelopment (GSU) level III» according to R. Levina's classification). The results of the study showed that the level of communication formation in the group of preschoolers with speech disorders is lower than inthe group of children with normal speech development. The lag in the formation of communication skills is represented by a number of indicators: «interest in a peer», «sensitivity», «prosocial actions», «means of communication», «active speech». Low self-esteem was found only in the group of children with speech impairments. There were no differences in the level of the sociometric status between children of both groups.

Fundamental modulation of energy metabolism in immune cells is increasingly being recognized for the ability to impart important changes in cellular properties. In homeostasis, cells of the innate immune system, such as monocytes, macrophages and dendritic cells (DCs), are enabled to respond rapidly to various forms of acute cellular and environmental stress, such as pathogens. In chronic stress milieus, these cells may undergo a re-programming, thereby triggering processes that may instigate tissue damage and failure of resolution. In settings of metabolic dysfunction, moieties such as excess sugars (glucose, fructose and sucrose) accumulate in the tissues and may form advanced glycation end products (AGEs), which are signaling ligands for the receptor for advanced glycation end products (RAGE). In addition, cellular accumulation of cholesterol species such as that occurring upon macrophage engulfment of dead/dying cells, presents these cells with a major challenge to metabolize/efflux excess cholesterol. RAGE contributes to reduced expression and activities of molecules mediating cholesterol efflux. This Review chronicles examples of the roles that sugars and cholesterol, via RAGE, play in immune cells in instigation of maladaptive cellular signaling and the mediation of chronic cellular stress. At this time, emerging roles for the ligand-RAGE axis in metabolism-mediated modulation of inflammatory signaling in immune cells are being unearthed and add to the growing body of factors underlying pathological immunometabolism.

Observations on natural history are a useful but often overlooked branch of ecology. With the use of camera-traps, collection of data e.g. on breeding behaviour and success has never been easier, particularly when studying cryptic species. Additionally, camera-traps are well suited to citizen science because of their ease of operation and the ability to store and verify data. Malleefowl Leipoa ocellata breeding behaviour has previously been studied through direct observation or timelapse photography, resulting in small sample sizes and potentially biased observations. Using camera-trap data collected by citizen scientists, we examined the breeding behaviour of this species. We quantified the timing and duration of mound-tending activities at 20 mounds using camera surveillance for >30,000 hours (1250 days) over six breeding seasons. Time spent at the mound during five mound stages and visit frequencies by the male and female during each stage are reported. Femaleinvolvement at the mound was consistent, although males spent three times as long at the mound compared with females during egg-laying. On egg-laying days, females spent longer uncovering the mound, compared with covering the mound post egg-laying. Our findings confirm that both male and female Malleefowl spend a substantial amount of time constructing and maintaining their mound throughout the year and, most notably, that the female consistently participates in mound-tending.These insights are particularly valuable as our surveillance was over markedly longer time spans than previous studies that relied upon direct observation.

Published: June 2021

Indonesia is one of the country having a lot of geothermal fields potentially used as a source of energy. For example, Java island is noted to have almost 57 geothermal fields. One of those geothermal fields which is rarely studied is Guci geothermal field. Hence, there was conducted a research to investigate the subsurface image and geothermal system in Guci geothermal field based on resistivity data. The research in Guci geothermal field was carried out using geoelectrical method. Resistivity geoelectrical research used two configurations, namely dipole-dipole and schlumberger. Data acquisitions for dipole-dipole configuration was done in two lines, 500 metres spread for each line. Whereas the acquisitions for schlumberger configuration was done in four points, 200-250 metres spread for each point. Research result showed that the area of geothermal manifestation in Guci consist of top soil layer, sandstone, andesite, and a fluids-containing layer. A fluids-containing layer is estimated to be related to geothermal manifestation in Guci and is a fault zone. Fault is estimated to be a normal fault and lies in 20 metres depth. Fault within geothermal manifestation area in Guci has a role as the pathway of hot-fluid out to the surface which forms a manifestation.

Indonesia is a country traversed by the Pacific ring of fire and is also the meeting point for tectonic plates, making it prone to various disasters including earthquakes. Many victims who fell during the earthquake disaster were due to a lack of understanding of the community in dealing with the disaster. An understanding of the community regarding earthquake disasters is needed to reduce the risk of earthquake disasters, one of which is done for students. Efforts to reduce earthquake risk can be done by developing earthquake learning media and applying it to students. The development of this learning media uses the 4D Model. The results showed that the use of earthquake learning media was effective in increasing students' understanding in dealing with earthquake disasters, so that this could unravel the risk of earthquake disasters for students.

Published: June 2021

The rapid development of Balikpapan City has an impact on the increasingly high demand for land for urban expansion needs. The expansion of Balikpapan City is more directed towards coastal areas which are dominated by mangrove forests. This study discusses the destruction of the mangrove forest and its causal factors and how conservation efforts are being carried out to maintain sustainability. Mangrove forest damage data obtained through surveys and image analysis using NDVI. While the factors causing the damage to mangrove forests were obtained from observations and interviews with the mangrove center manager of Balikpapan. The results showed that there were many mangrove forests that had rare or already damaged that were spread in the West Balikpapan, North Balikpapan, and East Balikpapan Sub-district. This damage is caused by natural and non-natural factors. Natural factors that cause damage to mangrove forests are pests and sedimentation. The non-natural factors are due to the pollution and the opening of fish ponds. Preservation efforts are carried out by replanting mangroves which are only carried out by the mangrove center and some CSR and environmentalists and do not involve the community at large. These Conditions make the mangrove forest in Balikpapan City threatened its sustainability.

Authors: Sivtsev N. S. , Tarasov V. V.
Published: June 2021

In recent years, the economic factor has played an increasingly important role in the selection of technologies for manufacturing machine parts with specified values of normalized parameters of geometric accuracy and quality of working surfaces. As applied to surface plastic deformation processes, this is noticeably manifested in the search for effective friction control methods in the “tool – workpiece” pair, which ultimately determines the distribution pattern and the magnitude of stresses and strains in the workpiece and the tool. It is not possible to obtain a rigorous analytical solution to the problem of establishing a connection between surface conditions, friction, and the stress-strain state of the contacted bodies. In this regard, the construction of mathematical models comes to the fore, the solution of which is possible by numerical methods. The paper presents the results of a numerical study (computational experiment) of a finite-element model of workpiece deformation under various conditions of contact interaction and friction by one of the methods of surface plastic deformation – surface mandrel drilling. The friction coefficient has been chosen as the criterion for assessing the conditions of contact interaction and friction. It is shown that a change in the friction coefficient in the process of surface mandrel has no noticeable effect on the formation of a stress field in the deformable workpiece both in the axial, and in the radial and circumferential directions. At the same time, with an increase in the value of the friction coefficient in the “tool – workpiece” pair and with the associated increase in the force of mechanical resistance to deformation of the workpiece, their growth is observed. A computational experiment has confirmed the presence of non-contact deformations of the workpiece and tool during surface mandrel drilling, as well as  as a decrease in the value of residual deformations in the workpiece with a decrease in the coefficient of friction. Balance assessment of contact surface displacements in the workpiece (the inner surface of the hole to be machined) and the tool (mandrel) has shown that the deformations of the tool in the elastic region can lead to a significant decrease in the real tightness of surface mandrel drilling.

Insect feces are a new kind of biological organic fertilizer. Little is known about the influences of insect feces on rice growth and heavy metal migration from soil to rice plant. In this study, the effects of different amounts (CK (0%), T1 (2%), T2 (4%), T3 (6%), and T4 (8%) ) of black soldier fly larvae (BSFL) feces on the rice growth and the migration/accumulation of heavy metals (Cd and Pb) were investigated by pot experiments within two years. The application of insect feces remarkably increased the contents of soil pH, organic matter, ammonium nitrogen, available phosphorus and potassium. Meanwhile, the insect feces application reduced the weak acid soluble contents of soil Cd and Pb by 8.3–56.8%, but increased those in the oxidizable (by 22.4–165.7%) and residual (by 1.8–225.6%) states. Except for the T4 treatment in the first year, all fertilization treatments increased the rice yield (up to 43.7% and 195.5% higher than those of CK within two years). Moreover, the insect feces application reduced the contents of Cd (8.3%-66.7%) and Pb (6.4%-61.8%) in different parts of rice. Under the same treatment, the metal contents in each part of rice in the second year were lower than those in the first year. The insect feces application decreased the absorption coefficients (24.4%-57.5%) and secondary transport coefficients (3.6%-44.1%) of Cd and Pb by rice plant.

Background: Cryptosporidiosis causes high morbidity and fatality to children under two years globally. The lack of an appropriate animal model that mimics the pathogenesis of disease in humans has hampered the development and testing of potential therapeutic options. This study aimed to develop and validate an infant baboon infection model of cryptosporidiosis.Methods: Eighteen immunocompetent weaned infant baboons aged 12 to 16 months were used. The animals were: n=3 controls and three experimental groups of n=5 animals each inoculated with Cryptosporidium parvum oocysts as follows: Group 1: 2x104, Group 2: 2x105, Group 3: 2x106 followed by daily fecal sampling for oocysts evaluation. Blood sampling for immunological assay was done on infection day and thereafter weekly until the end of the experiment followed by necropsy and histopathology. Statistical analysis was done using R, statistical package for the social sciences (SPSS) and Graph Pad Prism software. Analysis of variance (ANOVA) and Bonferroni post-hoc tests were used for comparison of the means, with p<0.05 considered as a significant difference. Correlation coefficient and Probit analysis were also performed.Results: In all experimental animals but not controls, the onset of oocysts shedding occurred between days 2 and 4, with the highest oocyst shedding occurring between days 6 and 28. Histological analysis revealed parasites establishment only in infected animals. Levels of cytokines (TNF-α, IFN-γ, and IL-10) significantly increased in experimental groups compared to controls. Conclusion: 2x104 oocysts were an effective minimum quantifiable experimental infection dose for developing a reproducible infant baboon model.
Theoretical Modeling for Predicting Material Removal Rate through Interelectrode Gap

In EDM, the thermal energy of the discharge causing material erosion which is supplied by the power source unit as electrical input. The discharge energy may be recognized by the current and voltage pulses on time transient discharge characteristic curve (V-I curve) during machining. However, the plasma resistance is very short for a smaller interelectrode gap in micro-EDM compared to the impedance of the circuit. Hence, direct probe-based measurement of current and voltage pulses may include the voltage drop across the stray impedance which causes variation in its exact value. Here, a modeling-based approach may help to analyze the energy interaction with the interelectrode gap. This article presents a theoretical modeling approach to predict the interelectrode gap based on gap voltage, gap current, and plasma characteristics. Initially, a simplified two-dimensional heat conduction equation (cylindrical form) was studied to understand the asymmetry of heat flow in Gaussian distribution. A numerical analysis of a single discharge pulse was considered by applying some basic assumptions. A numerical model has been developed to predict gap distance and MRR considering gap voltage, gap current, and plasma properties. The predicted model was validated against previously reported data from the literature. Later on, the impact of gap voltage on gap distance, plasma resistance, and material erosion rate was analyzed and discussed briefly.

Over the past few years, there has been a tremendous increase in the interest and enthusiasm for sports among people. This has led to an increase in the importance given to video recording of various sports that capture even the minutest detail using high-end equipment. Recording and analysis have thereby become extremely crucial in sports like soccer that involve several complex and fast events. Ball detection and tracking along with player analysis have emerged as an area of interest among a lot of analysts and researchers. This is because it helps coaches in performance assessment of the team and in decision making to obtain optimized results. Video analysis can additionally be used by coaches and recruiters to look for new, talented players based on their previously played games. Ball detection also plays a pivotal role in assisting the referees in making decisions at game-changing moments. However, as the ball is almost always moving, its shape-appearance keeps changing over time and it is frequently occluded by players, it makes it difficult to track it throughout the game. We propose a deep learning-based YOLOv3 model for the ball and player detection in broadcast soccer videos. Initially, the videos are processed and unnecessary parts like zoom-ins, replays, etc., are removed to obtain only the relevant frames from each game. Tracking is achieved using the SORT algorithm which employs a Kalman filtering and bounding box overlap.
