Eruption of a Magnetic Flux Rope in a Comprehensive Radiative Magnetohydrodynamic Simulation of Flare-productive Active Regions
Authors: Chen Feng , Rempel Matthias , Fan Yuhong
Published: June 2023

Radiative magnetohydrodynamic simulation includes sufficiently realistic physics to allow for the synthesis of remote sensing observables that can be quantitatively compared with observations. We analyze the largest flare in a simulation of the emergence of large flare-productive active regions described by Chen et al. The flare releases 4.5 × 1031 erg of magnetic energy and is accompanied by a spectacular coronal mass ejection. Synthetic soft X-ray flux of this flare reaches M2 class. The eruption reproduces many key features of observed solar eruptions. A preexisting magnetic flux rope is formed along the highly sheared polarity inversion line between a sunspot pair and is covered by an overlying multipole magnetic field. During the eruption, the progenitor flux rope actively reconnects with the canopy field and evolves to the large-scale multithermal flux rope that is observed in the corona. Meanwhile, the magnetic energy released via reconnection is channeled down to the lower atmosphere and gives rise to bright soft X-ray post-flare loops and flare ribbons that reproduce the morphology and dynamic evolution of observed flares. The model helps to shed light on questions of where and when the a flux rope may form and how the magnetic structures in an eruption are related to observable emission properties.
Photometric Monitoring of the ZZ Ceti Star PG 1541+651
Authors: Clausen Mabel E. , Williams Kurtis A.
Published: June 2023

The Kepler and K2 missions discovered multiple ZZ Ceti white dwarf pulsators that exhibit recurrent outbursts. These outbursting white dwarfs are near the red edge of the ZZ Ceti instability strip, suggesting that the phenomenon is physically related to the cessation of pulsations. We present multi-day ground-based monitoring of the poorly studied red-edge ZZ Ceti pulsator PG 1541+651. We do not detect any outbursts in our data. We do find that this pulsator has a very rich and time-variable spectrum of modes in its periodogram. The white dwarf lies in the northern continuous viewing zone of TESS; therefore, it has extensive archival light curves ripe for a detailed asteroseismic analysis of this star.
Problem-based learning using e-module: Does it effect on student’s high order thinking and learning interest in studying geography?
Authors: Wijayanto Bayu , Sumarmi Sumarmi , Hari Utomo Dwiyono , Handoyo Budi , Aliman Muhammad
Published: June 2023

High Order Thinking Skills (HOTS) are abilities that students in the 21st century must acquire. Problem-based learning is one of the learning models to improve high order thinking skills. E-module is an innovative teaching tools used in geography education. Geography is the main focus of education in the 21st century, especially related to environmental issues. This study aimed to determine the effect of PBL with e-module based on HOTS to student’s learning interest in studying geography. The research population consisted of second-year students (grade 11) of social class in SMAN 2 Semarang (Public Senior High School). This research used a factorial experimental design. The data was collected using a test measuring HOTS and a questionnaire measuring enthusiasm for learning geography. The data were analysed using statistics, including the normality test, the homogeneity test, and hypothesis testing with the T-test, linear regression, and two-way ANOVA. The results found that: 1) PBL with e-modules had a significant effect on HOTS; 2) student’s interest in studying geography had no significant effect on HOTS; 3) there was no effect between PBL and e-modules with student’s interest in studying geography on HOTS. The HOTS test results were unaffected by the increase or decrease in student’s interest. The HOTS is not influenced by student’s interest in studying geography, but rather by the actual learning; 4) the highest indicator of developing HOTS is the capacity for abstract thought; 5) students conclude that using e-modules in PBL can improve interest for solving environmental issues. The combination of e-module content with project-based learning motivates students to protect the environment.
A meshless method for numerical solutions of linear and nonlinear time-fractional Black-Scholes models
Authors: Ahmad Hijaz , Khan Muhammad Nawaz , Ahmad Imtiaz , Omri Mohamed , Alotaibi Maged F.
Published: June 2023

The numerical solution of the time-fractional Black-Scholes model for European and American options is presented using a local meshless collocation approach based on hybrid Gaussian-cubic radial basis functions with polynomials is presented. The approach is then expanded to a nonlinear time-fractional model for an option with transaction costs in a market with low liquidity. The spatial derivatives of the models are discretized using the proposed meshless technique. Numerical experiments are carried out for the American option, European option, and nonlinear transaction cost option models. In order to evaluate the effectiveness and precision of the suggested meshless approach, $ L_{\infty} $ and $ L_{rel} $ error norms are utilized. Both call and put option volatility is explored. A non-uniform grid customized around the strike price region is also used to determine the prices of European call and American put options. The methods described in literature are compared with the numerical results.
Dynamical analysis and boundedness for a generalized chaotic Lorenz model
Authors: Mao Xinna , Feng Hongwei , Al-Towailb Maryam A. , Saberi-Nik Hassan
Published: June 2023

The dynamical behavior of a 5-dimensional Lorenz model (5DLM) is investigated. Bifurcation diagrams address the chaotic and periodic behaviors associated with the bifurcation parameter. The Hamilton energy and its dependence on the stability of the dynamical system are presented. The global exponential attractive set (GEAS) is estimated in different 3-dimensional projection planes. A more conservative bound for the system is determined, that can be applied in synchronization and chaos control of dynamical systems. Finally, the finite time synchronization of the 5DLM, indicating the role of the ultimate bound for each variable, is studied. Simulations illustrate the effectiveness of the achieved theoretical results.

Authors: Küçük Dilek , Küçük Emine Ela
Published: June 2023

Domain ontologies are significant structured and semantic resources for information systems. Therefore, they are proposed and used in many application domains including medicine, finance, law, and energy. In this chapter, the authors extend a public health ontology in a semi-automatic manner in order to increase its usability in information systems and social media analysis applications. Basically, the public health ontology is extended with new concepts from a medical ontology, and it is partially aligned with this medical ontology. The final form of the ontology is named Public Health Ontology for Turkish (PHOTr). With this extension, the authors expect that the number and range of artificial intelligence applications that can benefit from the ontology will increase considerably. Also presented in this chapter are important future research directions based on the current study, in addition to information about the applications that can make use of PHOTr.

Published: June 2023

Humans are gifted when they born without any physical or mental disability. Also, till the end of their life, if no more physical disorder arises, they are doubly gifted. Unfortunately, this does not happen always. These disabilities have not been completely identified and severely affect life and lead to many problems in most of lives of affected people in terms of income. Also, few exceptions but exception cases are very little compared with the affected crowd. To solve this issue, a biomedical electronic component based on internet of things is proposed. More focus is given to devise a device for the interpretation of sign language of the deaf and dumb people for the interaction of impaired people with the normal people, and the interaction will increase with the aid of IoT-based devices. Further, the visually impaired people will not be able to move freely without assistance. The solution to this issue is presented as an IoT-based moving system. This will definitely be able to promote their life in terms of health and wealth, and this finds an important place to serve society.

Published: June 2023

The physical object or robotic arm movement in cyber physical system controlled through artificial intelligence algorithms impact on smart devices through marble marcher game is proposed in this work. The cyber physical object movement is framed from the fractal surface which can produce any difficult terrain producing more input for intelligent algorithms. Four different surfaces are framed from the parameters such as rows, columns, foundation functions and peak values. The surface governing equations split the surface as side of cubes controlling the six different geometric planes for extracting more data. These data used as input for taking decision done by intelligent algorithm from core input from the pixel-by-pixel analysis of the smart device input. The coordinate transformation produces more control variable for different factors and accuracy parameters. The simulation model developed in MATLAB language and the results shows that the proposed system enhances the data control and transfer with minimum hardware requirement.

Authors: Oladele Jumoke I. , Ndlovu Mdutshekelwa
Published: June 2023

The experience of the COVID-19 pandemic has revealed a need for the educational sector in Africa to adopt innovative ways for assessment by leveraging technology with the increasing number of student enrollments at all levels of education. A systematic approach is also required to circumvent the challenges faced by developing countries transdisciplinary. Transdisciplinarity is still evolving and has been proved to be a viable tool for engagement, societal impact, new partnerships, fresh ideas, reality checks, new capacities, and systemic thinking leading to new career possibilities. This study conducted a documentary analysis of standardised examination administration in Africa and proposed a framework for action adopting a transdisciplinary approach to research for problem-solving. The study used a qualitative approach for collecting and analysing data from reports and documents supported by empirical findings from existing literature. The study created a framework for action through which the gains of the transdisciplinary approach can be translated to practice.
Implementing UDL in a University Setting
Authors: Smidt Andy , Stanford Tonnette , Kminiak Dagmar , Montague Isobelle , Buhne Jessica
Published: June 2023

UDL principles are not consistently applied in the tertiary sector in Australia and appear infrequently in government policies. There is limited research about UDL in Australia and few studies that describe the challenges in implementing UDL across a whole tertiary institution. In this chapter the authors present an approach taken at the University of Sydney, focusing on supporting academics to understand UDL, identify areas in their own teaching that already use UDL principles, and select one or two new strategies to add to their courses each year. This approach starts with an acknowledgement that change is challenging, and that change can be incremental rather than requiring a whole course review to embed UDL principles. The authors identified institution-specific levels to support academics to choose strategies that would be relatively easy to implement. To date, teaching staff who have used these resources have found them valuable.
Towards Equity and Inclusion Excellence Using Diverse Interventions
Authors: Leifler Emma Kristina
Published: June 2023

Although inclusive education (i.e., education that does not include separate special education classes) is legislated and pervasive worldwide, the implementation of educational inclusion is poor. To create more inclusive school settings, we need to explore what constitutes good practice. Moreover, we need evidence of effective interventions that address student needs. This chapter provides evidence from two interventions aimed at improving inclusion (NDC AI and SKOLKONTAKT®). These mixed methods, which merge quantitative and qualitative data, show that professional development enhances the inclusive skills of teachers and group training of students improves social skills, school attendance, and participation, leading to less loneliness, making the whole school's social environment better. Unexpectedly, the teachers became more aware of social impairments and developed new concrete tools to handle conflicts and bullying.
Co-Teaching Collaboration in K–12 Inclusive Classrooms
Authors: Fleming Jennifer L. , Mullen Carol A.
Published: June 2023

Disseminating knowledge about instructional strategies in collaboratively taught K–12 classrooms can improve the learning environment for students with disabilities. This literature review identifies ways that co-teaching occurs in general education settings and is facilitated by stakeholders. Research questions were: What evidence-based strategies are utilized in cotaught K–12 inclusive classrooms? And how is the co-teaching initiative supported by the parties responsible for their development, implementation, and success? Evidence-based strategies for the general classroom are described along with stakeholder responsibilities. The comprehensive synthesis of salient sources is US based and limited in applicability. Practitioners might consider the solutions and recommendations presented when navigating co-teaching and inclusive practices. Trends favor the instructional co-teaching approach for infusing inclusive strategies, and support research and application. This analysis contributes to the growing body of research on effective collaborative teaching strategies.
The Universal Design for Learning in the Context of Brazilian Education
Authors: Costa-Renders Elizabete Cristina
Published: June 2023

The topic discussed in this chapter is teacher professional development committed to inclusive education. The text presents partial results of a research on the application of the principles of universal design for learning in school inclusion processes in Brazilian schools. It aims to present and reflect on the reports of the participating teachers about the challenges and possibilities of building inclusive education based on UDL. On the one hand, the challenges consist of difficulties in designing activities to include all students considering the class heterogeneity, the institutional bureaucratization that compromises the time to plan teaching, and the scarce means to overcome such difficulties. On the other hand, advances demand the democratic management of school, the ethical leap arising from inclusive education, and the epistemological supports of universal design for learning and pedagogy of seasons. The results of the introduction of UDL are promising and show improvements, but structures and skills need a more permanent pedagogical companionship.
Higher Education for Refugees
Authors: Saeed Sameerah T. , Mustafa Falah
Published: June 2023

This chapter examines how different countries allow refugees to pursue higher education. Policy and practice comparisons will be made between the United Kingdom, Germany, and France. In many industrialized countries, refugees are able to pursue higher education. This is an important part of integrating these individuals into the societies in which they reside. However, depending on the country, there may be differences in the process of qualification recognition, the tuition fees, and the availability of scholarships and financial assistance. Moreover, the policies and practices in the three selected countries emphasize access to higher education, and offer opportunities for participation, while neglecting the aspect of social inclusion related to empowerment. The findings may assist institutions of higher education in determining which policies to adopt in order to provide quality higher education to refugees and enable them to integrate more effectively.

Published: June 2023

Sensors are effective instruments for finding illegal drugs. In the past several years, sensor use and development have garnered a lot of interest. The lack of an effective tool that offers the specialist all the necessary features, including cost-effective manufacturing, on-site analysis, instrumental simplicity, and correct findings, might be blamed for this thirst for the creation of new detectors. Nanotechnology has the potential to significantly advance forensic science and criminal investigation. In forensic nanotechnology, tiny chip materials are employed in place of large apparatus, which simplifies the techniques of analysis and improves the accuracy, precision, timeliness, and suitability of investigations. The reader is provided with up-to-date studies and publications as this chapter describes the use of nano sensors in forensics investigation. Additionally, it details the key distinctions between the three major categories of sensors that provide information on the potential applications of these sensing materials in the future.

Authors: Muller S. Raschid , Burrell Darrell Norman , Nobles Calvin , Mingo Horace C. , Vassilakos Andreas
Published: June 2023

Interference in the election process from both abroad and within the United States has produced chaos and confusion in business markets, communities, and among voters. Elections have become less reliable as a result of misleading statements. Election deniers are actively working to undermine confidence in our elections and suppress turnout, particularly among voters of color and other communities that have historically been marginalized. The false information spread, which includes lies about the voting process and election workers, has the potential to have significant repercussions for people's abilities to vote and their faith in our elections. Election misinformation poses a threat to democratic processes in the United States. Sixty-four percent of election officials reported in 2022 that spreading false information had made their jobs more dangerous. This chapter uses emerging content from extant literature to discuss cyberpsychology and the complex dynamics of these issues with a primary focus on finding solutions to these problems.
The Complement-Targeted Inhibitor Mini-FH Protects against Experimental Periodontitis via Both C3-Dependent and C3-Independent Mechanisms

Published: June 2023

A minimized version of complement factor H (FH), designated mini-FH, was previously engineered combining the N-terminal regulatory domains (short consensus repeat [SCR]1–4) and C-terminal host-surface recognition domains (SCR19–20) of the parent molecule. Mini-FH conferred enhanced protection, as compared with FH, in an ex vivo model of paroxysmal nocturnal hemoglobinuria driven by alternative pathway dysregulation. In the current study, we tested whether and how mini-FH could block another complement-mediated disease, namely periodontitis. In a mouse model of ligature-induced periodontitis (LIP), mini-FH inhibited periodontal inflammation and bone loss in wild-type mice. Although LIP-subjected C3-deficient mice are protected relative to wild-type littermates and exhibit only modest bone loss, mini-FH strikingly inhibited bone loss even in C3-deficient mice. However, mini-FH failed to inhibit ligature-induced bone loss in mice doubly deficient in C3 and CD11b. These findings indicate that mini-FH can inhibit experimental periodontitis even in a manner that is independent of its complement regulatory activity and is mediated by complement receptor 3 (CD11b/CD18). Consistent with this notion, a complement receptor 3–interacting recombinant FH segment that lacks complement regulatory activity (specifically encompassing SCRs 19 and 20; FH19–20) was also able to suppress bone loss in LIP-subjected C3-deficient mice. In conclusion, mini-FH appears to be a promising candidate therapeutic for periodontitis by virtue of its ability to suppress bone loss via mechanisms that both include and go beyond its complement regulatory activity.

Authors: Aggarwal Shivali , Batra Jayati , Singla Aanchal , Gupta Sharang , Chopra Preeyati , Chopra Dimple
Published: June 2023

Background:

Acne vulgaris is a common disorder of pilosebaceous units affecting adolescents and young adults. The various causes include diet, stress, seborrhea, and premenstrual flare.

Objective:

The objective of this study was to compare lipid profile, insulin, and adiponectin levels in acne and controls.

Materials and Methods:

Sixty patients of acne from the age group of 12 to 25 years and 20 healthy age- and gender-matched controls were included in the study.

Results:

Patients with acne showed significantly higher levels of total cholesterol and low-density lipoprotein (LDL), higher levels (although not statistically significant) of triglyceride, and very LDL and significantly lower levels of high-density lipoprotein as compared to controls. Furthermore, individuals with acne had significantly lower levels of serum adiponectin and significantly higher mean levels of fasting serum insulin as compared to controls.

Conclusion:

Derangements in serum lipid profile, serum insulin, and serum adiponectin levels can predispose to acne in adolescent individuals. Thus, dietary and lifestyle modifications should be recommended in such patients.

Authors: Sadang Jonaid M. , Palompon Daisy R. , Agoncillo Deane Joy E. , Datumanong Namera T. , Alawiya Jamal Tango P.
Published: June 2023

Background: Few studies have been conducted on unique conditions such as coronavirus disease 2019 (COVID-19) as an emerging health emergency, despite the strong link between resilience and quality of life in older persons. This study validated the expanded need-threat internal resiliency theory, which claims that an older person who establishes a strong sense of internal resiliency adapts to the situation by maintaining a better disposition. Methods: The underlying methodology in this study was a qualitative design using multiple case studies with non-probability purposive sampling to choose the target participants aged 60 years and above.Results: This cross-case analysis showed two major themes that explained and described the similarities and differences between the internal resiliency and quality of life of older adult participants with their respective sub-themes. Furthermore, this study concluded that older adults who have developed a strong sense of internal resilience, as manifested in the participants’ coping strategies during the COVID-19 pandemic, have sustained quality of life and better life satisfaction.Conclusion: The study proposes a shift in the perspective of aging by emphasizing the importance of resilience as a dynamic process helping in the coping process and adapting to new emerging pandemics, leading to improved quality of life amid adversity.

Pediatric critical care medicine (PCCM), as it is practiced in high-income countries, is focused on specialized medical care for the most vulnerable pediatric patient populations. However, best practices for provision of that care globally are lacking. Thus, PCCM research and education programming can potentially fill significant knowledge gaps by facilitating the development of evidence-based clinical guidelines that reduce child mortality on a global scale. Malaria remains a leading cause of pediatric mortality worldwide. The Blantyre Malaria Project (BMP) is a research and clinical care collaborative that has focused on reducing the public health burden of pediatric cerebral malaria in Malawi since 1986. In 2017, the requirements of a new research study led to the creation of PCCM services in Blantyre, creating the opportunity to establish a PCCM-Global Health Research Fellowship by BMP in collaboration with the University of Maryland School of Medicine. In this perspective piece, we reflect on the evolution of the PCCM-Global Health research fellowship. Although the specifics of this fellowship are out of the scope of this perspective, we discuss the context allowing for the development of this program and explore some early lessons learned to consider for future capacity-building efforts in the future of PCCM-Global Health research.
Impact of Sampling Time, Actuation/measurement Delays and Controller Calibration on Closed-loop Frequency Response for Non-linear Systems
Authors: Rostiti Cristian
Published: June 2023

During input tracking, closed-loop performance is strongly influenced by the dynamic of the system under control. Internal and external delays, such as actuation and measurement delays, have a detrimental effect on the bandwidth and stability. Additionally, production controllers are discrete in nature and the sampling time selection is another critical factor to be considered. In this paper we analyze the impact of both transported delay and controller sampling time on tracking performance using an electric machine speed-control problem as an example. A simple linear PI controller is used for this exercise. Furthermore, we show how the PI parameters can be adjusted to maintain a certain level of performance as the delays and sampling times are modified. This is achieved through an optimization algorithm that minimizes a specifically designed cost function.

Modern life is full of stressful situations, so the study of the level of stress in various social groups has become especially relevant in recent years.

The main purpose of our study was to study the level of stress in today's youth. We also found it interesting to compare and determine whether there would be a difference in the level of stress among working and non-working young people who are only engaged in studies. In addition, we wanted to study the situation of young people living in urban and mountainous areas. According to the existing hypothesis, the level of stress among the inhabitants of the highlands should be significantly lower than that of the inhabitants of the city. We also found it interesting to study depression rates, here again on the assumption that depression rates would be significantly higher among urban youth than those living in the regions.

The results obtained allow us to conclude that students who are employed during their studies have an overall stress score almost twice as high as students who are not employed.

As the second stage of the study showed, our assumption that city dwellers would have a significantly higher level of stress was not confirmed. There is a difference, but a minor one.

As for the study of the level of depression, the results showed that the percentage of depressive states among students living in the city and region is very small. However, this study once again confirmed the link between stress levels and depression.

When looking back the history of mankind, the modern constitutionalism has still the significant meaning in Contemporary Social State Constitution on which its development is based today in that the freedom and the rights of people started to be guaranteed as the modern constitutionalism was established in the era when monarch used to exercise tyrannical sovereignty for a long time. Today, the constitution holding the status of highest law in the country regulates to restrict the arbitrary exercise of sovereignty through separation of power as a mechanism for guaranteeing the rights of the people and realizing them, and it still has the regulatory meaning in these days in that the starting point is the modern constituionalism constitution. Because the country in which the basic rights are guaranteed by constitution is often called the constitutional state, the constitutionalism and the constitutional state are inseparable. Modern constitutionalism presupposes modernity in terms of time, but it did not end in modern times, and its normative contents are still alive in today's Contemporary Social State Constitution. This study reviews the establishment of modern constitutionalism constitution from this view, and also examines how the normative contents are transformed and applied in Today’s Contemporary Social State Constitution. The results to compare Contemporary Social State Constitution with constitutionalism show, first, change from a night view state to a social state, second, substantialization of National Sovereignty, third, strengthening social rights guaranteeing from guaranteeing freedom, fourth, transition from formal rule of law to practical rule of law, fifth, securing the highest norm of the constitution through the constitution trial system. In comparison with modern constitutionalism, the normative contents of modern constitutionalism still have the effective meaning in Contemporary Social State Constitution, but it is shown as a characteristic of the Contemporary Social State Constitution. Like this, because the normative contents of constitutionalism still function as a key content in Contemporary Social State Constitution as well, it is said that the comparison of modern constitutionalism and Contemporary Social State Constitution is significant.
