Authors: Leskina Irina
Published: February 2022

The article discusses the problem of managing the effectiveness of a teacher's professional activity in the context of an increase in the speed of the processes of generating data on education in a digital educational environment. The article presents a procedural model of organizing management of the effectiveness of the teacher's professional activity based on work with big data in general education, developed and approved by the Nizhny Novgorod Institute of Education Development, which is a basic component of an in-school system for assessing the quality of education, focused on the implementation of systematic work with different types and composition of data based on complex competences of teachers (professional and digital) in the field of Big Data in education. Introduced into the scientific circulation of the theory and methodology of vocational education, the concept of "complex professional competencies" in relation to teachers working with big data in education, the formation of which is a prerequisite for the implementation of effective professional activities of a teacher in a modern school. Within the framework of the project study, focused on testing the hypothesis about the conditions and mechanisms for managing the effectiveness of the teacher's professional activity in the new conditions, the main approaches to the formation of complex competencies of the teacher in the field of Big Data in education have been identified, problem areas in the teacher's activities have been identified that complicate the process of their formation and improvement and possible ways to eliminate them, a list of indicators of the effectiveness of the teacher's professional activity in the field of Big Data in education has been determined. The practical application of the developed procedural model for managing the effectiveness of the teacher's professional activity is important for creating conditions in a modern school for educational activities that fully satisfy the needs and demands of all participants in educational relations.

Development of the phenomenon of "mentoring" in pedagogical science and practice
Authors: Medvedev Yan
Published: February 2022

The article examines the phenomenon of the emergence and development of mentoring. The development stages, the place and role of mentoring in pedagogy and education are analyzed. In the Russian Empire, the institution of classroom mentoring took shape in the second half of the 19th century, when it was secured by law. The practice of mentoring became widespread in the United States of America as part of social work with children in the early 20th century. The main characteristics of mentoring are presented. In its most general form, mentoring can be defined as a way of transferring knowledge, skills and attitudes from a more experienced person to a less experienced one. Based on the analysis of open literature sources describing the phenomenon of “mentoring”, as well as the experience of implementing mentoring activities in professional educational organizations, the problems of the development of the Institute of Mentoring have been

The Effects of Writing Strategy Instruction on EFL Learners’ Writing Development
Authors: Chen Ai-hua
Published: February 2022

This study examined the effects of integrating writing strategy training into EFL writing instruction on learners’ strategy use and writing performance. Two classes of EFL adult learners participated in this study. The experimental group were instructed with the writing strategy training in their EFL writing class for 14 weeks, whereas the control group received the same EFL writing program without any explicit strategy training. 

Mixed methods were applied in collecting data. The quantitative instruments included the writing strategy questionnaires and writing performance tests, which were both pre-tested and post-tested in the both groups. The qualitative instruments of reflective journals were also conducted in the experimental group to probe deeper insights into learners’ strategy changes. The findings showed that there were significantly positive differences in learners’ using writing strategies and in writing proficiency favoring the experimental group. 

The findings of this study indicate that writing strategy training can be integrated in the EFL writing instruction, and can bring to positive impacts for learners’ strategic awareness and writing strategy use as well as their writing performance. The paper suggested the strong need to the process-based writing instruction, and writing strategy training holds promise in this regard.
The Budget Deficit Financing Impact on the Real Exchange Rate in Egypt (1975-2020)
Authors: Eldepcy Mohamed A.
Published: February 2022

The Purpose of this paper is to examines empirically The causal impact of budget deficit financing methods on real exchange rate in Egypt during the period from 1975 to 2020.The main question of the paper whether there is a causal relationship between the large fluctuations in the real exchange rate and budget deficit/GDP proportion, governed by specific predictable factors, in particular the method of financing the budget deficit.

Using structure vector autoregressive (SVAR) framework with variable lag structure, our empirical results provide evidence of the contribution of the money supply ratio to the GDP in the fluctuations of the real exchange rate in the short and medium terms, while the contribution of non-bank financing expressed in the real interest rate contributed to a lesser degree in these fluctuations, which gives an indication of the expansion in the use of local bank financing to finance the budget deficit during the study period. Moreover, the results showed that the government’s dependence on local sources in financing the budget deficit was large, especially the local bank financing. It was also found that the non-banking domestic sources of funding have less influence on the fluctuations of the real exchange rate and therefore the value of the Egyptian pound relative to the US dollar. furthermore, also found out that the periods in which the real exchange rate index decreased and the value of the pound improved, are the periods in which the reliance on non-banking domestic financing was greater than on domestic banking financing, namely the periods from 1993-1997, and from 2005-2010.

This paper aims to contribute to filling the gap in the applied literature that examined the relationship between the budget deficit and external imbalance by focusing on the role of the means of financing the budget deficit.

Published: February 2022

Background. The consequences of the COVID-19 pandemic include the emergence or intensification of negative emotional states, such as anxiety disorders or depression. The deterioration of the emotional state in human population can be explained by the severe increase in the level of psychological stress related to the pandemic. In turn, mental stress can lead to the appearance or exacerbation of psychosomatic symptoms. Mental stress is one of the risk factors for bruxism. Due to the current pandemic situation, there is an increase in the frequency of bruxism symptoms in the population.
The aim of this study was to analyze the occurrence of bruxism symptoms in sports climbers during the COVID-19 pandemic.
Material and methods. The study consisted of two stages - the first one was carried out in August 2019 and the second one was repeated in May 2020, three months after the national quarantine in Poland had been announced . 67 people in the control group and 67 in the studied group were qualified for the study. The occurrence of awake and sleep bruxism was determined using a questionnaire.
Results. The collective analysis showed that the studied group had a lower percentage of respondents with awake bruxism compared to the control group - the results reached the required threshold of statistical significance. The prevalence of sleep bruxism between the groups was similar - the differences did not reach the assumed significance threshold.
Conclusions. The level of bruxism symptoms among climbers was significantly lower during the COVID-19 pandemic than before it. The obtained results and possible adaptation mechanisms in climbers require further analysis.
Physiological and histological conditionings of articular cartilage regeneration techniques and clinical application of these techniques
Authors: Włodarski Krzysztof H. , Szczęsny Grzegorz , Brodzikowska Aniela
Published: February 2022

In clinical setting no spectacular treatment results confirmed using histological ap­proaches were noted as compared with these obtained in laboratory research (finding the regeneration built of the hyaline cartilage in the damaged area in the treated patients is very rare since, as a rule the regeneration is built of the fibrous cartilage).
Numerous and increasingly frequent procedures aimed at regeneration of the articular cartilage using platelet rich plasma (PRP), isolated autogenous chondrocytes or mesenchymal precursor cells in patients with osteoarthritis provide access to the vast research material for the analysis of the efficacy and safety of the treatment, based on which, no definitely adverse consequences of the applied methods were no­ted, such as life-threatening consequences due to new tissue formation. However, the knowledge of the underlying mechanisms indicates the necessity of exercising caution in qualifying patients for such procedures and many years long monitoring in order to the fastest possible diagnosing and successful treatment of the complications. \
The relationship between field test results measuring physical fitness levels in olympic boxing competitors and their athletic performance
Authors: Kowalik Norbert
Published: February 2022

Background. The aim of the study was to find physical discriminants in Polish senior league elite boxers
Material and methods. 13 competitors from the senior national team of average age and body mass participated in the study. The applied methods of assessment included FMS and CMJ tests, 3kg medicine ball throw and 1200m shuttle run.
Results. Statistical analysis of the studied biomechanical variables compared with the results of the Polish Senior Championships and the yearly rank list did not reveal any significant correlation.
Conclusions. The lack of a clear physical indicator may indicate that the determinants of success in sports depend on other competitors’ traits. On the other hand, the small sample size may be the reason of the lack of statistical significance. An adequate level of physical capacities may allow effective use of the athlete’s vast potential, however, it is not the only decisive factor affecting success in boxing.

Os sistemas de apoio à decisão beneficiam-se de padrões ocultos (semi-)extraídos automaticamente de grandes bases de dados. No domínio específico da caracterização de gastrópodes, dados e medidas morfológicas podem apoiar os biólogos na identificação de caramujos terrestres. Embora lesmas e caramujos possam ser facilmente identificados por seus sistemas excretório e reprodutivo, o corpo do molusco é comumente inacessível por causa da deterioração do material macio ou da fossilização da concha. O presente artigo tem, como objetivo, investigar a performance de um classificador baseado em instâncias, quando aplicado sobre um conjunto de dados com características morfológicas de conchas de caracóis terrestres. Avaliações experimentais indicam que um método proposto alcançou acurácia superior a 99% na identificação de espécies de caramujos.

Physical Activity Levels and Self-perception of Fitness in COVID-19-Recovered Individuals
Authors: Azmodeh Mahnaz , Hoseini Rastegar , Amiri Ehsan
Published: February 2022

Background: The preventative measures to reduce the incidence of coronavirus disease 2019 (COVID-19) have reduced the physical activity level (PAL) that might also affect physical and mental health. Objectives: The present study investigated the relationship between self-perception of fitness (SPF) and PAL in COVID-19-recovered individuals (CRI). Methods: The population of this descriptive-analytical study included all CRI (men and women, in the age range of 20 to 70 years) in Kermanshah. In the present study, 890 volunteers (438 men and 452 women) were sampled using a multistage cluster sampling method. The International Physical Activity Questionnaire (IPAQ-SF) was used to assess the PAL and the Delignières et al. questionnaire to assess the SPF. The Pearson correlation coefficient test and independent t-test were used to analyze the data using SPSS version 24 software. Results: The results showed low PAL (men: 876.11 ± 40.23; women: 739.27 ± 8.02) and poor SPF (men: 6.64 ± 1.62; women: 5.27 ± 1.39) in CRI. Also, there was a significant positive relationship between high and moderate PAL and SPF in men (r = 0.67, P = 0.032; r = 0.77, P = 0.018, respectively) and women (R = 0.56, P = 0.041; r = 0.66, P = 0.035, respectively), while there was a significant inverse relationship between low PAL and SPF among men (r = -0.85, P = 0.001) and women (r = -0.89, P = 0.001). Conclusions: Based on the results, wrong SPF in individuals with low PAL might be one reason for being insufficiently active. Thus, a proper understanding of PAL could be the first step of a regular physical activity schedule to enhance the immune system.

Authors: Sharma Malika , Khade Asha S , Bhoi Umesh , Gaurkar Sudarshan
Published: February 2022

: Focal dermal hypoplasia, popularly known as the goltz syndrome, is an extremely rare multisystem disorder mainly involving the skin, skeletal system, and eyes. Being an X-linked dominant disorder, focal dermal hypoplasia mainly affects females (95%) and is lethal in males. Few affected males who survive are mosaics. The mutation is found on the PORCN gene on the X chromosome. Only about 250 - 300 cases have been reported in the literature. It is a type of ectodermal dysplasia interrupting the development and functioning of the skin, hairs, nails, teeth, eyes, and the skeletal system. Accordingly, a wide variety of clinical manifestations are noticed, the diagnosis of which is primarily on a clinical basis. The present study reports one such case of goltz syndrome presented with a giant cell tumor of the right distal fibula, ie, a minor criterion for diagnosing goltz syndrome. Further detailed examination led to the diagnosis of goltz syndrome. We wish to highlight the importance of minor criteria and the major ones to diagnose goltz syndrome. The patient had skin lesions since birth and had no complaints associated with it. It was the pain and swelling associated with the giant cell tumor that brought the case to notice of physician.
Memory of Oblivion and Oblivion of Memory
Authors: Ćurak Nerzuk ,   Center for Peace and Justice Education at Villanova University
Published: February 2022

Nationalist narratives in Bosnia and Herzegovina generate organized hypocrisy against the culture of memory which involves different protagonists of this society. The real name of the culture of memory of Bosnia and Herzegovina is the culture of denial. This is the very structure of its culture. By examining the perpetuation of memory into organized oblivion as a particular form of structural and cultural violence, the author will establish scholarly and axiological criteria in favor of the creation of conditions to end the culture of oblivion. In contrast to the ontology of oblivion, as an instrument of the culture of denial, this article affirms Emmanuel Levinas’s principle of the responsibility for the Other, as a relationship of pure holiness, as an a priori ethical requirement. Also, to reinforce the argument in favor of a responsible culture of memory in the face of its ideological stagnation, the author also examined critical objection to culture of memory by radical left intellectuals, in whose view culture of memory inhibits emancipation of the oppressed class. Although such argumentation should not be dismissed outright, it dances around the reality of post-conflict communities like Bosnia and Herzegovina, where war victims cry for justice, and hold it as important as their very existence.
(A)symmetrical Conflict between Medical Doctors and Traditional and Faith Healers in the Era of Covid-19 in Rural Communities of Zimbabwe
Authors: Chirambwi Kudakwashe ,   Center for Peace and Justice Education at Villanova University
Published: February 2022

The paper examines the tension in the social construction of pandemic by doctors, traditional healers, and faith-based healers and considers the potential public health implications. Methodologically, the author uses a case study of Mwenezi District in Masvingo Province in Zimbabwe and draws on autoethnographic experiences to observe and analyse local level asymmetric confrontations as the Coronavirus pandemic unfolded. What emerges is how values, beliefs and scientific interpretations are contributing factors to conflict, and more significantly, the deleterious impact it has on mobilizing community action against the pandemic. Research findings reveal how untenable and inconceivable it will be to contain the pandemic without paying appropriate attention to apostolic sects and traditional healers. Interventions have so far ignored this social capital.
Solutions to Displacement
Authors: Kaufmann Lily ,   Center for Peace and Justice Education at Villanova University
Published: February 2022

As displacement increases due to conflict and climate change, it is vital to find permanent solutions to the global refugee crisis. Currently, refugees are predominantly hosted in less-developed states, to the detriment of both the refugees and the communities providing shelter, while developed states with the financial capacity to provide permanent resettlement restrict the number of refugees accepted. Despite anti-immigrant rhetoric, many developed countries are dependent on economic immigrants to provide population influx and economic growth. Examining this dependency while exploring the social factors which facilitate successful newcomer integration, this paper proposes an immigration system which balances the ratio of refugees and economic immigrants to encourage an equitable system of resettlement. Linking refugee resettlement with economic immigration addresses the needs of refugees, ameliorates pressure on less-developed states currently hosting refugees and serves the national self-interest of developed countries.
Two Contemporary Developments of Kant’s Cosmopolitan Project
Authors: Chen Jinghua ,   Center for Peace and Justice Education at Villanova University
Published: February 2022

Habermas and Rawls presented distinctive theories of new world order at the turn of the new century: the Constitutionalization of International Law and the Law of Peoples. Both theories aim to promote peace and justice all over the world. Unfortunately, their theories have been ignored by mainstream IR theorists. Since few scholars make a deep comparative study between Rawls’s Law of Peoples and Habermas’s Constitutionalization of International Law to reveal their crucial difference, this paper aims to fill this gap by clarifying their essential difference and preliminarily exploring how to formulate their proper relationship. I argue that Habermas’s project is a legalistic peace theory. In contrast, Rawls’s Law of Peoples is a modified form of democratic peace theory, putting hope for international peace on the improvement of the domestic political system of sovereign entities. Finally, I present a tentative suggestion to address their relationship, returning to Kant’s systems approach.
The Canadian Federal Department of Peace Initiative
Authors: Kliewer Victor , Byrne Sean ,   Center for Peace and Justice Education at Villanova University
Published: February 2022

This article examines the possibility of establishing a Department of Peace (DOP) as a Department of the Government of Canada. The topic has been introduced in Parliament twice, as Bill C-447 in 2009 and as Bill C-373 in 2011, without any further actions beyond the formal First Reading. The introduction of the bills could only happen on the basis of significant support among Canadians. At present efforts to introduce the DOP continue, although in somewhat muted form. Based largely on oral interviews, this article assesses the potential for establishing a DOP in the context of the Canadian peace tradition as well as global developments. It concludes that a DOP has great potential to move the peace agenda forward but that, in view of the priorities of the current government and the general mood in Canadian society, it is not realistic to expect a DOP to be implemented at present.
Comparison of conventional and new endoscopic band ligation devices for colonic diverticular bleeding
Authors: Takasu Ayaka , Ikeya Takashi , Shiratori Yasutoshi
Published: February 2022

Background/Aims: Endoscopic band ligation (EBL) is used to treat colonic diverticular bleeding (CDB). An endoscopic variceal ligation device for esophageal varices is used as a conventional EBL device (C-EBL). A new EBL device (N-EBL) was developed by Sumitomo Bakelite Co. in August 2018. We aimed to evaluate the clinical outcomes of N-EBL compared with those of C-EBL.Methods: Seventy-nine patients who underwent EBL for CDB at St. Luke’s International Hospital, Japan, between 2017 and 2020 were included in this retrospective study. Patients were divided into the C-EBL and N-EBL groups. Their clinical outcomes, including achieving initial hemostasis, early rebleeding, procedure time, and EBL-associated adverse events, were evaluated.Results: Of the 79 patients, 36 (45.6%) were in the C-EBL group and 43 (54.4%) were in the N-EBL group. The rate of achieving initial hemostasis was 100% in the C-EBL group and 93.0% in the N-EBL group. No significant difference was noted in the early rebleeding rate between the groups (p=0.24). The N-EBL group achieved a shorter median EBL procedure time than the C-EBL group (18.2 minutes vs. 14.2 minutes, p=0.02). No adverse events were observed in either group.Conclusions: The N-EBL device is safe and useful and may reduce EBL procedure time.
An in-depth analysis of the side hop test in patients 9 months following anterior cruciate ligament reconstruction
Authors: Urhausen AP , Gette P , Mouton C , Seil R , Cabri J , Theisen D
Published: February 2022

Purpose: The current criterion to evaluate 30-second side hop (SH) test performance following anterior cruciate ligament reconstruction (ACLR) is limited to the absolute number of jumps, neglecting the quality of execution. This study aims to assess the relevance of spatiotemporal and force plate derived parameters during the SH test. Methods: Seventeen patients nine months post-surgery and 27 healthy controls were instructed to realize a maximal number of jumps during 30 seconds over a 40 cm-distance. Spatiotemporal and force plate derived variables were recorded from two force plates: number of jumps, flight time, contact time, jump distance, vertical impact force, average and instantaneous vertical loading rate. Group (patients and controls) by leg (non-operated/first tested and operated/second tested) interactions were tested using a mixed model analysis of variance. Results: Patients performed a similar number of jumps compared to controls. No differences were found for spatiotemporal and force plate derived parameters, neither for lateral nor medial jumps. High interindividual spread of impact peak forces existed in both groups. Discussion: Patients 9 months following ACLR and successful rehabilitation can safely perform strenuous lateral hops similar to controls. Although the force plate derived parameters during the SH test were normalized compared to controls, impact peak forces outlined particularly high loading parameters in some participants. Applying biomechanical analysis in association to the commonly used clinical parameters helps to point out individual and potentially harmful loading strategies during the SH test.

Published: February 2022

Protective efficiency of inhibitors of the "INCORGAZ" and "AMDOR" series is analyzed in relation to carbon steel corrosion in model stratum waters of oil and gas fields saturated with hydrogen sulfide and carbon dioxide separately and together. The bactericidal properties of the inhibitors with respect to sulfate-reducing bacteria, reduction of steel hydrogenation, influence on the preservation of metal plastic properties are evaluated. The contributions of the inhibitor and the shielding film of corrosion products to the total protective effect are considered. The inhibitors under study provide a decrease in the corrosion rate of carbon steel to a value much less than 0.05 mm/year, according to the data of 240-hour exposure in hydrogen sulfide environments.
Nano-Metal Stability and its Outcomes
Authors: Vigdorowitsch Michael
Published: February 2022

A thermodynamics-based approach to determining stability conditions for metallic nano-ensembles is proposed. It is related to that [ultra-]dispersing the substance leads to changes in thermodynamic potentials (TPs) compared to those of a massive crystal of the same nature. This dimensional phenomenon consists of two components. Among those are a reduction of TPs due to vacancy-related effects and an increase of TPs due to the surface tension effect. Even linear, exponential, and normal distributions of particles on their size in the ensemble have been considered. The resulting equations have been applied to the nano-ensembles of either In or Au particles. The presence of ultra-small particles in an ensemble makes the vacancy-related effect more apparent than the surface tension effect, promoting system stability. With the decrease in the number of ultra-small particles, the vacancy-related effect drastically diminishes and can yield to the surface tension effect, thereby leading to the loss of stability.
Influence of Reduced Air Pollution Source Emission Information on User Behavioural Intention Towards E-Scooter Products
Authors: HUANG Fei-Hui
Published: February 2022

In this study, a mobile application-based service providing information on the reduction in the air pollution source emissions due to the replacement of conventional scooters by electric scooters (e-scooters) was proposed to increase user awareness of air quality and purchase intention towards e-scooters. The extended unified theory of acceptance and use of technology was employed and an explanatory variable of environmental awareness (EA) was incorporated for enhancing constructs to investigate the factors that may influence the user acceptance of text-based mobile information on the reduced carbon emissions, in comparison with that of histogram-based mobile information on the reduction in emissions of six air pollution sources. A within-subjects experimental design was employed to evaluate both information contents. The results indicate that the model constructs of habit and EA are useful predictors of the behavioural intention (BI) to use app services. Furthermore, providing different mobile information contents demonstrated no statistically significant difference in the user’s acceptance and intentions. However, providing different mobile information contents on the same information spindle may trigger different constructs and intensities of influence on users’ purchase intentions for e-scooters. Based on these findings, several recommendations for app managers and developers and suggestions for future research have been provided.
Simulation Based-MCDM Approach for Evaluating Traffic Solutions
Authors: MAGHABLEH Ghazi , MUMANI Ahmad
Published: February 2022

Traffic congestion problems have dramatically esca-lated with the increasing volume of vehicles, pedestrians, and cyclists in the face of limited road capacity. This re-search aims to reduce the time road users spend in the system (school-zone area) and improve the efficiency of the process of dropping off and collecting children from a crowded school area. The study integrates discrete-event simulation (DES) and multi-criterion decision-mak-ing (MCDM) techniques to comprehensively evaluate the proposed alternatives to select an optimal solution based on many performance measures. A real-world case study of the traffic and congestion problems experienced by parents when they drop off and fetch their children from school during peak hours is presented. A heuristic algorithm was developed to simulate the random and un-predictable behaviour of road users. A cost-benefit anal-ysis considered the impact of waiting time, traffic den-sity, number of accidents, additional fuel expenses, and emission reduction. The technique for order of preference by similarity to ideal solution (TOPSIS) and preference selection index (PSI) methods were utilised to select the most appropriate option for parents. The study found that the integration of simulation techniques with MCDM methods could efficiently solve traffic problems.

In this research, field and laboratory testing of three commercially available brake pads with the lowest, mid-dle, and highest price were performed. Complex field testing, where brake pads were tested in real extreme conditions on a loaded van vehicle and laboratory tests were performed. The field testing intended to investigate the temperatures that occur during the braking process and to determine the stopping distance, deceleration, and stopping time separately on the type of brake pads. Labo-ratory tests included the determination of the friction co-efficient according to ASTM G77, the structure of brake pad surfaces before and after the testing, and quantitative chemical analysis of brake pads. The aim of this study was to determine the influence of brake pad temperature on braking time depending on their purchase prices. The obtained results show a significant difference between the temperature, friction coefficient, chemical composi-tion, and braking time of the brake pads and their price.

Hong-Ou-Mandel (HOM) interference is a non-classical effect of photons and plays an important role in quantum optics. The β-barium borate (BBO) has a high nonlinear efficiency, and is commonly used to generate biphoton states, thereby exhibiting HOM interference. However, in previous experiments, researchers often used band-pass filters, so the resulting spectrum was directly determined by the band-pass filter. As a result, the original spectrum of the BBO crystal, especially the spectrum under tight focusing, was lack of systematic research. In this paper, the biphoton spectral distribution and HOM interference generated by the BBO crystal under the condition of tight focusing are systematically studied for the first time. Theoretical calculations show that using a lens with 50-mm focusing length, the spectral width of the down-converted photons is increased by 7.9 times that of the non-focused case; the width of the HOM interference fringe is reduced to 1/8, and the visibility of the interference fringe increases from 53.0% to 98.7%. We experimentally prepare the energy-time entanglement state by using type-II BBO crystal and perform HOM interference, thereby obtaining the interference visibility of \begin{document}$(86.6 \pm 1.0)$\end{document}%. The increasing of the HOM visibility is due to the improvement of biphoton's spectral symmetry. In addition, the proposed technique by which different spectral distributions are obtained at different incident angles is expected to be applied to the preparation of high-dimensional qudits in the future.

Published: February 2022

This note considers some real and complex extensions and generalizations of the Leonardo sequence, which is embedded within each of these two types of intriguing sequences, intriguing because there are still some unanswered questions. The connections between inhomogeneous and homogeneous forms are used as examples of a possible reason that the Leonardo sequences have been, in a sense, historically neglected.

Myofibers are the main components of skeletal muscle, which is the largest tissue in the body. Myofibers are highly adaptive and can be altered under different biological and disease conditions. Therefore, transcriptional and epigenetic studies on myofibers are crucial to discover how chromatin alterations occur in the skeletal muscle under different conditions. However, due to the heterogenous nature of skeletal muscle, studying myofibers in isolation proves to be a challenging task. Single-cell sequencing has permitted the study of the epigenome of isolated myonuclei. While this provides sequencing with high dimensionality, the sequencing depth is lacking, which makes comparisons between different biological conditions difficult. Here, we report the first implementation of single myofiber ATAC-Seq, which allows for the sequencing of an individual myofiber at a depth sufficient for peak calling and for comparative analysis of chromatin accessibility under various physiological and disease conditions. Application of this technique revealed significant differences in chromatin accessibility between resting and regenerating myofibers, as well as between myofibers from a mouse model of Duchenne Muscular Dystrophy (mdx) and wild-type (WT) counterparts. This technique can lead to a wide application in the identification of chromatin regulatory elements and epigenetic mechanisms in muscle fibers during development and in muscle-wasting diseases.

Corona Virus Disease 2019 (COVID-19) pandemic has increased the importance of Virtual Learning Environments (VLEs) instigating students to study from their homes. Every day a tremendous amount of data is generated when students interact with VLEs to perform different activities and access learning material. To make the generated data useful, it must be processed and managed by the proper machine learning (ML) algorithm. ML algorithms’ applications are many folds with Education Data Mining (EDM) and Learning Analytics (LA) as their major fields. ML algorithms are commonly used to process raw data to discover hidden patterns and construct a model to make future predictions, such as predicting students’ performance, dropouts, engagement, etc. However, in VLE, it is important to select the right and most applicable ML algorithm to give the best performance results. In this study, we aim to improve those ML and DL algorithms’ performance that give an inferior performance in terms of performance, accuracy, precision, recall, and F1 score. Several ML algorithms were applied on Open University Learning Analytics (OULA) dataset to reveal which one offers the best results in terms of performance, accuracy, precision, recall, and F1 score. Two popular ML algorithms called Decision Tree (DT) and Feed-Forward Neural Network (FFNN) provided unsatisfactory results. They were selected and experimented with various techniques such as grid search cross-validation, adaptive boosting, extreme gradient boosting, early stopping, feature engineering, and dropping inactive neurons to improve their performance scores. Moreover, we also determined the feature weights/importance in predicting the students’ study performance, leading to the design and development of the adaptive learning system. The ML techniques and the methods used in this research study can be used by instructors/administrators to optimize learning content and provide informed guidance to students, thus improving their learning experience and making it exciting and adaptive.
