A variety of fractional soliton solutions for three important coupled models arising in mathematical physics

This paper deals with the optical solitons of fractional coupled Boussinesq, Burgers-type and mKdV equations by the hypothesis of traveling wave and [Formula: see text]-expansion scheme. These equations are important in different fields such as propagation of long water waves, fluid dynamics, and shallow water wave propagation. In comparison to other analytical procedures, the analytical methodology [Formula: see text] is an incredibly beneficial approach. This technique can also be used with other nonlinear fractional models. The suggested method generates three distinct solutions such as trigonometric, hyperbolic, and rational. Moreover, graphical representation has been used to portray the physical significance of the constructed solutions. Finally, a comprehensive study is made by using a definition of Beta fractional derivative and obtained solutions are represented graphically to understand considered models.

Role of rehabilitation amidst the COVID-19 pandemic: a review

COVID-19 remains globally a highly infectious disease targeting multiple organs. Rehabilitation is increasingly valued among the supportive care fields to combat COVID-19 as currently definitive curative treatment remains largely absent. This narrative review is to address rehabilitation related topics associated with the treatment of COVID-19 patients. Nosocomial spread remains a high risk for healthcare workers, with comparable high ratios of exposed workers suffering from the disease with more severe clinical course. Primary principle of rehabilitation is to protect rehabilitation physicians and cover all person-to-person interactions. Translating perspectives are encouraged through each multidisciplinary approach. Rehabilitation for the outpatient remains a potential beneficial approach. Artificial intelligence can potentially provide aid and possible answers to important problems that may emerge involving COVID-19. The real value of rehabilitation in COVID-19 may be very impactful and beneficial for patient’s physical and mental health.

The Polish Experience in the Development of Smart Cities

In recent years, Poland has seen an increased migration of people to cities, which translates into significant urban population growth. This, in turn, raises new challenges in the performance of cities’ tasks and responsibilities. Additionally, climate changes and the depletion of natural resources necessitate the modification of existing urban practices. Polish cities seek solutions which would enable social, economic and environmental demands to be reconciled so that urban spaces become friendly for the city’s inhabitants and investors. Some Polish cities have applied the smart city concept to solve their problems. Despite the fact that the concept has been the subject of scientific research for many years, no universal definition of the smart city has been agreed upon. Analyzed assumptions of the smart city concept as well as the Polish experiences in the implementation indicate that the concept is dynamic and changes over time. It should be considered as a perpetual process unrestricted by a specific timeframe. This impedes the formulation of uniform, generally accepted assumptions of the concept since its existence is inscribed in the change related to urban development. This article claims that this would be a beneficial approach for formulating the general characteristics of the smart city that could be applicable to any city, and that could be employed regardless of the present challenges cities may face.

Hypocholesterolemia and Statins in Multiple Myeloma

Statins are lipid-lowering agents. They also have immunomodulatory, anti-inflammatory, anti-angiogenic, and anti-proliferative functions. In this context, they are demonstrated to have beneficial effects on mortality in several malignancies including esophageal, breast, lung, liver, pancreatic, endometrial, and colorectal cancers. Multiple myeloma is considered as an incurable plasma cell disorder with current therapy; however due to the current knowledge about the correlation between cholesterol-lowering agents and myeloma; it’s suggested to have lower mortality rates for patients using statins. Patients with multiple myeloma usually have a low cholesterol level which is often underestimated by clinicians. Hereby we aimed to summarize the myeloma-hypocholesterolemia relationship and emphasize the importance of statins as an inexpensive and beneficial approach for these patients.

To Compete or Cooperate? Intermunicipal Management of Overtourism

Is it beneficial for municipalities to cooperate or compete with one another to attract visitors? The myopic rationality of game theory favors competition for short-term gains, whereas the nonmyopic theory of moves suggests that cooperation in this regard might be more farsighted, consensual, inclusive, and sustainable. To understand why popular cities switched to cooperation when faced with the crisis of overtourism, even though the players’ preferences about the outcomes did not change, we analyzed the case study of Amsterdam. The results indicate that the theories are appropriate in different situations. Thus, the theory of moves’ rules—alternating choices, thinking ahead in making choices—are more appropriate to finding a solution that would be stable in the future, not just one that is myopically stable in the present. We conclude that cooperation remains a more beneficial approach to managing tourism even in periods of undertourism. Policy directions are provided.

Performance Evaluation of a Hybrid Solar Collector in Two Different Climates

The solar hybrid collector (PV/T) modules are a beneficial approach that simultaneously transforms solar radiation into heat and electric power. This work examined the performance of a PV/T module with flat-plate absorber type and water-cooled by optimizing the PV/T model under two significantly different climate conditions. The first is for Stuttgart city, and the second is for Kabul. According to what has been conducted in this study, Kabul has a higher percentage of the received heat energy than Stuttgart, at more than 50.4%. Furthermore, Kabul's electrical efficiency is 48.3% higher than Stuttgart's. As a matter of fact, the annual radiation of Kabul is more than Stuttgart city by 49.12%. Thus, Kabul city seems to be more convenient than Stuttgart for the PV/T applications.

Mobile Games for a house museum.

The paper discusses a formal didactic activity in a higher education context, which brought to the design, development, and testing of thirteen Location-Based Mobile Games (LBMGs) for the Bagatti Valsecchi House Museum. The activity involved BSc Design students in developing and testing interactive solutions aimed at reaching out to the "under 35" community of the museum with engaging and entertaining experiences. For this purpose, the stakeholder group of the museum experts was also involved in co-designing the solutions. On the one hand, this study focuses on the beneficial approach of involving Design students in the multiple roles of designer, player/visitor, and target audience. On the other hand, it looks at those aspects that may turn LBMGs into a means for engaging and entertaining museum visitors' experiences. We focus on four LBMGs (out of thirteen) that the museum selected to be tested with their younger community, highlighting those elements that emerged as particularly relevant for enhancing visitors' engagement and motivations. In this regard, three aspects stand out as the most impacting: (i) the benefits of a design approach based on the early involvement of both experts (the museum) and the target audience (students themselves); (ii) an intelligent orchestration of narratives and game mechanics, specifically designed to leverage the fascinating museum space, and (iii) the ability of such games to stimulate social engagement.

Supporting Peer Feedback on Learning Strategies: Effects on Self-Efficacy and Feedback Quality

The study focused on supporting the distinct processes of assessment and providing feedback within a peer feedback setting in teacher education and investigates the effects on student teachers’ self-efficacy and feedback quality in a quasi-experiment. Student teachers ( n = 129) were asked to repeatedly provide peer feedback on learning strategies and were supported by a digital tool. The support was varied: support in assessment (A; realized by rubrics), in formulating the feedback (F; by providing sentence starters), in both components (A+F), or no support (Control). We conducted a 2 × 2 analysis of variance (ANOVA) to measure the effect on feedback quality and 2 × 2×2 mixed ANOVAs to investigate the effects on self-efficacy. Results revealed that student teachers perceived higher self-efficacy regarding assessing learning strategies and giving feedback after repeatedly giving and receiving peer feedback. While supporting feedback-writing (F) was immediately beneficial for students’ self-efficacy, the combination (A + F) was most advantageous in the long run. In addition, feedback quality was higher when students were supported in writing the feedback. The findings show that competencies to assess and to give feedback seem to be distinct components that should be fostered individually. The developed support by the digital tool seems to be one beneficial approach here.

Multicriteria optimization of a novel degradable nonwoven mulch fabricated from recycled natural fibers using CV-TOPSIS technique

Conventional polyethylene mulch is widely used in arid areas; however, excess residues have caused significant problems, such as tillage soil pollution, crop destruction, and food crisis. To solve these problems, new types of degradable nonwoven mulch fabricated from recycled natural fibers are proposed in this study, which are measured by field trial performances based on cotton yield and quality indicators, and prioritized by the Coefficient of Variation-Technique for Order Preference by Similarity to Ideal Solution (CV-TOPSIS) method. The results from this study indicate the suitability of the new mulch in cropping systems. Moreover, based on the CV-TOPSIS method, five mulch samples were prioritized as N-3 > N-4 > N-1 > N-2 > N-5, considering an agricultural evaluation. This study also confirmed that the CV-TOPSIS method was precise and robust for analyzing comprehensive agronomic assessments. The development of a new degradable nonwoven mulch provides a bidirectionally beneficial approach for recycling industrial waste fibers and for enhancing agricultural production. The comprehensive evaluation method for both crop quantity and quality introduces an efficient assessment of various mulch. In the future, deducing the parameters of the degradable nonwoven mulch design and optimizing this method requires further study.
