The ∞-Fucík spectrum

In this article we study the behavior as p ↗ +∞ of the Fučik spectrum for p-Laplace operator with zero Dirichlet boundary conditions in a bounded domain Ω ⊂ Rn. We characterize the limit equation, and we provide a description of the limit spectrum. Furthermore, we show some explicit computations of the spectrum for certain configurations of the domain.
Cardiovascular Topics Study of the mechanism of Shexiang Baoxin pill-mediated angiogenesis in acute myocardial infarction

Aim: The Shexiang Baoxin pill (SBP) is a commonly used drug for the treatment of coronary artery disease in China. More recently, some studies have found that it improved coronary microvascular function. This study aimed to explore the possible mechanism by which the SBP promotes angiogenesis after acute myocardial infarction (AMI). Methods: A rabbit model of acute myocardial infarction was established by ligating the left anterior descending coronary artery with silk thread, and the limb lead electrocardiogram was recorded to determine the success of the model. The rabbits were divided into a control group (SBP + normal rabbit group), a sham operation group, a saline + AMI group and an SBP + AMI group. There were 10 rabbits in each group. The animals were sacrificed and myocardial tissue was collected seven days after the operation. Haematoxylin–eosin staining was used to observe the histological changes in the rabbit myocardium in each group. The degree of acute myocardial infarction was observed with picric acid staining, which was used to detect the expression of vascular endothelial growth factor (VEGF), silent information regulator 1 (SIRT1), Beclin1 and mTOR protein in the myocardial tissue of each group. Immunofluorescence CD31-labelled microvascular density (MVD) was used to observe the vascular regeneration of the rabbits in each group. Results: Compared with the normal saline + AMI group, the myocardial infarction area of the SBP + AMI group decreased and CD31 immunofluorescence-labelled MVD increased. Compared with the control and sham operation groups, the expression of VEGF, Beclin1 and mTOR in the normal saline + AMI group and the SBP + AMI group increased, while the expression of SIRT1 decreased. Compared with the normal saline + AMI group and the SBP + AMI group, the positive expression of VEGF, Beclin1, mTOR and SIRT1 in the SBP + AMI group was significantly increased. Conclusion: Autophagy was enhanced after acute myocardial infarction. SBP may affect angiogenesis through the SIRT1/ mTOR signalling pathway after acute myocardial infarction to inhibit ventricular remodelling and a decline in cardiac function.
Reflections on the 2021 Nobel Memorial Prize Awarded to David Card, Joshua Angrist, and Guido Imbens

The 2021 Sveriges Riksbank Prize in Economic Sciences in Memory of Al-fred Nobel was awarded in two halves. One half was awarded to David Card “for his empirical contributions to labour economics” (The Royal Swedish Academy of Sciences 2021, 1). The other half was awarded jointly to Joshua D. Angrist and Guido W. Imbens “for their methodological contributions to the analysis of causal relationships” (1). In this article, I (a philosopher of science interested in causal inference in economics) reflect on the second half of the 2021 Nobel Prize, awarded to Angrist and Imbens. Two beautiful examples of causal inference in economics are Angrist (1990) and Angrist and Krueger (1991), published shortly after Joshua Angrist obtained his PhD in 1989. (His co-laureates David Card and Guido Imbens are his contemporaries, obtaining their PhDs in 1983 and 1991, respectively.) The 1990 study estimates the causal effect of veteran status on earnings 30 years later. It finds that white U.S. veterans from the Vietnam War have approximately 15% lower earnings as a result of military service. The 1991 study finds that, in the U.S., having an additional year of compulsory schooling has a large effect on earnings later in life (An-grist and Krueger 1991).
ENABLERS AND HINDRANCES TO FARMERS’ PARTICIPATION IN PRODUCTION OF FARMER-LEARNING VIDEOS IN CENTRAL UGANDA: A THEMATIC ANALYSIS

Videos can complement extension services provision by improving dissemination of agricultural information to farmers. However, for videos to be effective, they need to have relevant video content. This study assessed enablers and hindrances to farmers’ participation in FLV production based on a coffee FLV. Identifying enablers and hindrances to participation of farmers in production of an FLV is essential for developing strategies that optimise their participation to produce relevant FLVs aligned to their contexts. A qualitative case study research design was employed. Data were collected through focus group discussions, key informant interviews and in-depth interviews, and analysed through thematic analysis guided by the Activity theory analytical framework. The study established that farmers’ attributes especially their competencies to accomplish assigned tasks in FLV production, and motivations, were salient enablers to their participation. The other enablers were related to how the FLV process was organised, which included availability and adequacy of requisite resources, existence of clear guidelines for production of FLV, utilisation of pre-existing relationships, skilfulness of video experts and field officers, and specificity of roles. The limited interactions among actors, differing expectations, and time constraints were the major hindrances to farmers’ participation in production of the FLV. Hence, video experts should provide opportunities for improving farmers’ competences through training, offering technical support, and providing for rehearsals to build confidence. Mechanisms for improving interactions between and among farmers and video experts to harmonise expectations, promote mutual understanding, and foster knowledge sharing are also needed.
Compact Low-Profile Wideband Omnidirectional Circularly Polarized Patch Antenna with reconfigurable polarization

— A compact polarization reconfigurable wideband omnidirectional circularly polarized (CP) antenna is presented in this paper. This design is based on a low profile omnidirectional CP antenna which consists of a microstrip antenna working on TM 01 /TM 02 modes with slots etched on the ground plane. Vias are introduced between the patch and the ground plane, in order to excite the TM01 and TM02 modes which generate vertically polarized electric field within a wide frequency band. Sequential bended slots are introduced on the ground plane to radiate horizontally polarized electric field. As the result of the combined radiations from both the patch antenna and the sequential slots, left hand circularly polarized (LHCP) omnidirectional radiation pattern is obtained. The polarization reconfigurable is realized by introducing PIN diodes on the slots and through controlling the states of the PIN diodes, the effective orientation of the slots on ground plane can be adjusted and the polarization of this antenna can be altered between LHCP and RHCP (right hand circularly polarization). To verify this design concept, one LHCP and one polarization reconfigurable prototypes at 2.4GHz band were designed and fabricated. Experimental results show good agreement with the simulation results. The LHCP antenna exhibits a wide impedance bandwidth of 18.4% from 2.12 to 2.57 GHz and 3dB-axial ratio (AR) bandwidth of 450MHz. For the polarization reconfigurable antenna, 19.8% (2.09 GHz -2.55 GHz) overlapped 3 dB AR and 10 dB impedance bandwidths is obtained. The present design has thickness of only 0. 024λ and exhibit stable CP omnidirectional conical-beam radiation patterns within the operating frequency band with good circularly polarization.
Efficient Entity Resolution Method for Heterogeneous Information Spaces

: Even cutting-edge instanced matching methods cannot perform as expected when they are required to be employed in matching instances over heterogeneous datasets. Such drawback is caused by their essential functioning depending on the direct matching that necessitates direct correlation between instances in origin among instances in any given target dataset. This direct matching may not be appropriate in the case of overlap among datasets being small. In order to resolve this problem, a new model known as class-based matching is proposed here. Under a type of instances drawn from the original dataset, known as the type of interest and some group of participant matches recalled from the mark, class-based matching purifies the participants through filtering out such contenders who are not related to the type of interest. Related to this transformation, only the data present inside the target will be used—it does not involve direct contrasting among the original and the end. The type of interest happens to be a type of instances drawn from the original dataset. The class-based matching can be defined to be a group of contender matches that are recalled from target. The contender purification process can be performed through filtering out such candidates who do not relate to the type of interest. For such kind of purification, just the data present in the end dataset is being used which describes that no involvement of direct contrasting among the original and target. Depending on public benchmarks regarding difficult matching job, this method immensely enhances the cutting-edge systems quality.

FLUX: Design Education in a Changing World

This paper is based on research conducted for a PhD (completed in 2006) that aimed to develop a methodology for the systematic and strategic fostering of creativity in graphic design education at university or college level. The methodology incorporated three main strategies for enhancing creativity in an educational context, namely the teaching of (1) ‘product-related’ techniques that include a range of thinking strategies which could be used to generate creative ideas, (2) ‘process-related’ techniques that deal with the various phases of the creative process and how to manage them effectively and (3) ‘person-related’ techniques that address the socio-psychological factors which tend to influence creative abilities. The synergy of these three dimensions has been integrated into a course in creative thinking skills which is currently being taught at the North-West University in Potchefstroom, South Africa. This paper addresses the question that was of fundamental importance to the purposes of the PhD research, namely whether creativity can be purposefully taught. Within the limited scope of this paper it is only possible to partially answer this question. In order to arrive at a satisfactory answer to this question, all three dimensions mentioned above should be addressed, with cognisance of the complexity of each aspect as well as their interactivity and interdependence. For the purposes of this paper, however, the most ‘teachable’ dimension is selected for discussion, namely the ability to effectively generate original ideas. It aims to address the question of whether creativity can be taught by means of an overview of a series of idea-generation techniques that is currently taught at the North-West University to develop graphic design students’ ability to generate original ideas.

Commercial Electricity Demand Modeling: Do Regional Differences Matter?

One of the key benefits of understanding regional electricity consumption and its response to policy changes is enhancing the decision-making process. In Saudi Arabia, energy policies are set at the national level, and assessing their impacts at the regional level provides valuable insights for assessing the impact of previous and future policies. The regions of Saudi Arabia have unique social and economic characteristics (Mikayilov et al. 2020b) and are expected to react differently to changing policies.
The Factors Affecting Purchase Intention of university students in Fast Food Industry in Quetta. Pakistan

Purchase intention is a crucial factor that affects fast food usage as it reflects the individual's willingness to buy a product or service. In the fast-food industry, purchase intention is particularly important because it can determine the success or failure of a business. If a consumer has a positive purchase intention towards a particular fast-food brand, it is more likely that they will purchase from that brand repeatedly. On the other hand, if a consumer has a negative purchase intention, they may choose to purchase from a competitor or not purchase at all. This article explores the factors that influence the purchase intention of university students in Quetta, Pakistan, in the fast-food industry. The aim of this study is to explore the factors namely, physical environment and health consciousness which affect the purchase intension of universities students. The study uses a quantitative approach, and data was collected from 300 university students through a self-administered questionnaire. Statistics software (SPSS V23) was used to analyze the data. The results indicate that factors such as physical environment and health cautiousness have a significant impact on the purchase intention of university students. Furthermore, the study also suggests that demographic variables such as gender, age, and income have a moderate influence on purchase intention. The findings of this study have important implications for fast-food businesses operating in Quetta, as they can use these factors to develop effective marketing strategies to target the university student market.
Evaluation of the gastrointestinal and metabolic effect in a murine model of a high-fiber snack

This work aimed to evaluate the gastrointestinal and metabolic effect in a murine model of a snack rich in fiber (corn, chickpea, sesame, and chia) (HFS) and the comparison with the consumption of a commercial corn snack (CMS). Unlike the commercial snack, the mixture of corn, chickpea, sesame, and chia improved the nutritional quality of the final product. In the evaluation of the intake of the different diets in the mouse model, high-fiber snack (HFS) decreased cholesterol and triglyceride levels after 30 days of consumption, while CMS increased glucose levels and caused metaplasia in gastric tissue, in addition to decreasing the height villus in small intestinal tissue. The reformulation of snacks, using in addition to cereals, legumes, and oilseeds, can be a functional food easily accessible to the population, being a better option than snacks of low nutritional quality that are on the market.
Perceptions of administrative policymaking authority: Evidence from interviews in three state court systems

Using elite interviews, this paper explores how actors in state courts in the United States perceived and performed their administrative policymaking capacity during the COVID-19 pandemic. It argues that considering both hierarchical and local control explanations of the behavior of those working in courts offers a more nuanced explanation of the distribution of administrative authority in these systems. The interviews reveal that actors in court systems that both concentrate and distribute administrative authority behave in ways that contradict the prevailing explanatory models – in more administratively decentralized systems, some court actors sought more guidance from central actors whereas in a centralized system, some court actors acted in ways that deviated from central commands. In addition to expanding our understanding of the consequences of centralized and decentralized administrative authority for court users, this paper provides evidence of the benefits and challenges of conducting technology-mediated interviews with an elite sample
Hierarchical sliding mode control for a two-dimensional ball segway that is a class of a second-order underactuated system

Ball segway, a ballbot-type personal carrier robot, is an actual under-actuated system with second-order nonholonomic velocity constraints and input coupling case. The two-dimensional ball segway system has two outputs consisting of ball position and body tilt angle, which needs to be controlled but has only one torque driving the ball. Actuators directly drive the ball and the body has no direct control. The main objective of this study is to design a robust controller for the ball segway so that the ball is transferred in a point-to-point motion while the body is maintained in the vertical position. The proposed controller is designed on the basis of hierarchical sliding mode control technique. Both simulations and experiments were conducted to verify the quality and stability of the control system.
FACTORS INFLUENCING THE ATTITUDES OF SECONDARY SCHOOL STUDENTS TOWARDS THE STUDY OF MATHEMETICS.

It is a known fact that there exist behavioral difficulties among Mathematics students in Estiwani as a result of unresolved attitudinal issues that either the students are not aware of, or that the issues are not properly dealt with. This work seeks to investigate some factors influencing the attitude of secondary school students toward studying Mathematics in the Manzini region. Five schools consisting of two boys-only, two girls-only, and one mixed school were been carefully selected for the investigation. A total of 200 students and 15 qualified teachers were randomly and actively engaged. A combination of the discrete and continuous data collected through observations and using a well-designed questionnaire was carefully analyzed from their graphical representations. It was found that the majority of the students showed a huge gap in the content knowledge and also presented a clear negative attitude towards Mathematics as a subject. Some of the factors responsible for this worrying pattern, as shown by the analysis include poor background from their primary schools, ineffective teaching methods by their teachers, and lack of motivation by their parents among others. Training programs for teachers particularly on the use of technology and teaching aids to better disseminate the contents and the rewards were also highlighte

Conclusion
Stochastic finite integration technique for magnetostatic problems

Both nonintrusive and intrusive stochastic approaches on the basis of polynomial chaos expansion are presented for the finite integration technique over generic polyhedral grids for 3D magnetostatic linear problems. Such algorithms outperform Monte Carlo methods (when the number of random parameters is small), both in accuracy and efficiency. A novel algorithm for the intrusive approach is also provided, by which the intrusive approach becomes less computationally expensive than the nonintrusive approach. Validation is performed by solving a magnetic circuit where the reluctivity is uncertain.
Evaluation of Innovation Adaptive Bureaucracy in Disruption Era: A Case Study of Drive Thru Services in Tax Payments in South Sulawesi Province

An adaptive bureaucracy will be able to produce effective and efficient innovations in order to achieve goals in the era of disruption. Innovation is born. Innovation, which essentially requires coherence of sectoral policies, national-regional policies, and innovation governance systems, will not be effective if the policies of various sectors are partial, fragmented, inconsistent and even contradict one another. This study aims to evaluate innovation as a form of adaptive bureaucracy. through a case study of the implementation of Drive Thru services in the tax payment process in South Sulawesi Province. This study uses a qualitative approach. Data sources include primary and secondary data. Data collection includes observation, in-depth interviews and documentation. Analysis of research data used is interactive analysis which includes data collection, data reduction, data presentation and drawing conclusions. The results of this study indicate that drive thru service innovation is a manifestation of the adaptive bureaucracy of the South Sulawesi Provincial Government in responding to the digital disruption era. However, these innovations require development so that they are able to respond to dynamic public needs. It is important to improve the quality of the adaptive bureaucracy so that it is able to develop better innovations and periodically evaluate the implemented innovations.
