Increasing the size of radio frequency (RF) reflectors in space can enhance gain and spatial resolution in applications such as space-based communication and remote sensing. The size of current passive deployable reflectors is limited by a tradeoff between diameter and surface precision, which causes RF performance to degrade as size increases. A promising approach to overcome this tradeoff is to combine in-space manufacturing, which enables large structures, with distributed embedded actuation, which enables precise control over the reflector surface. Here we demonstrate a reflector antenna system that integrates these two technologies, using a candidate in-space manufacturing process, termed “Bend-Forming,” with embedded electrostatic actuators. We design and fabricate a 1-m-diam prototype of an electrostatically actuated X-band reflector with a knitted gold-molybdenum mesh as the reflector surface, carbon-fiber-reinforced plastic booms as electrodes, and a truss support structure fabricated with Bend-Forming. We characterize the RF performance of this reflector, successfully demonstrating i) control over a wide range of focal lengths by suppressing a pull-in instability and ii) beam steering over an angular range of 4.2° via asymmetric electrostatic actuation. This work lays the foundation for future space communication and remote sensing technologies, offering a scalable solution to enhance RF performance through in-space manufacturing and precision control.
Near-Field Aeroacoustic Shape Optimization at Low Reynolds Numbers
Authors: Hamedi Mohsen , Vermeire Brian
Published: April 2024

We investigate the feasibility of gradient-free aeroacoustic shape optimization using the flux reconstruction (FR) approach to study two-dimensional flow at low Reynolds numbers. The overall sound pressure level (OASPL) is computed via the direct acoustic approach, and optimization is performed using the gradient-free mesh adaptive direct search (MADS) algorithm. The proposed framework is assessed across three problems. First, flow over an open cavity is investigated at a Reynolds number of [Formula: see text] and freestream Mach number of [Formula: see text], resulting in a 7.9 dB noise reduction. The second case considers tandem cylinders at [Formula: see text] and [Formula: see text], achieving a 16.5 dB noise reduction by optimizing the distance between the cylinders and their diameter ratio. Finally, a NACA0012 airfoil is optimized at [Formula: see text] and [Formula: see text] to reduce trailing edge noise. The airfoil’s shape is optimized to generate a new four-digit NACA airfoil at an appropriate angle of attack to reduce OASPL while maintaining the baseline time-averaged lift coefficient and preventing an increase in the baseline time-averaged drag coefficient. The optimized airfoil is silent at 0 dB and the drag coefficient is decreased by 24.95%. These results demonstrate the feasibility of shape optimization using MADS and FR for aeroacoustic design.
Aerodynamic Prediction of the High-Lift Common Research Model with Modified Turbulence Model
Authors: Zhang Shaoguang , Li Haoran , Zhang Yufei
Published: April 2024

Aerodynamic simulations were carried out in the study presented in this paper focusing on the stall performance of the High-Lift Common Research Model obtained from the fourth AIAA High-Lift Prediction Workshop. Various turbulence models of Reynolds-averaged Navier–Stokes simulations are analyzed. A modified version of the transitional [Formula: see text] model was developed to enhance stall prediction accuracy for high-lift configurations with a nacelle chine. The vortex generator, three-element airfoil, and high-lift model are numerically simulated. The results reveal that implementing a [Formula: see text] model with the separation shear layer fixed notably enhances the stall prediction behavior for both the three-element airfoil and high-lift configuration without affecting the prediction of the vortex strength of a vortex generator. Moreover, incorporating rotation correction into the SPF [Formula: see text] model improves the prediction of vortex strength and further enhances stall prediction for the high-lift configuration. The relative error in predicting the maximum lift coefficient is less than 5% of the experimental data. The study also investigated the impact of the nacelle chine on the stall behavior of the high-lift configuration. The results demonstrate that the chine vortex can mitigate the adverse effects of the nacelle/pylon vortex system and increase the maximum lift coefficient.
Central Bank Independence, Inflation and Money Growth: Evidence from South Africa
Authors: Vermeulen Cobus
Published: April 2024

Purpose: This article evaluates the impact of the de jure independence of the South African Reserve Bank (SARB) on the credibility and discipline of domestic monetary policy. Credibility captures the extent to which economic agents trust the SARB to pursue its price stability mandate and is measured by the relationship between the SARB’s independence and domestic inflation. Discipline relates to the effect of independence on money growth rates, while independence is associated with a more disciplined central bank and moderate money growth rates.
Methodology: A simple autoregressive distributed lag (ARDL) econometric specification and Granger causality tests are employed. Following the extant empirical literature, existing indexes of central bank independence (CBI) are regressed on annual rates of inflation and M2 money growth.
Findings: A statistically significant negative relationship is established between both i) CBI and inflation and ii) CBI and money growth for the South African economy. This suggests that the SARB’s legal independence plays an important role in containing inflation (credibility) and limiting excessive money growth (discipline).
Contribution: This article fills a gap in the extant literature by being the first attempt at formalising the empirical link between de jure CBI, inflation, and the rate of money growth in the South African economy.
Navigating Source Code Plagiarism Challenges: Strategies to Mitigate the Impact of COVID-19 Disruptions
Authors: Du Plessis Linda , Smit Imelda
Published: April 2024

In South Africa, the immediate response to the COVID-19 pandemic was a hard lockdown, which shocked the educational community.  The disruption to teaching and learning was particularly profound for first-year computing students, especially those with disadvantaged backgrounds. One of the biggest impacts of emergency remote teaching and learning was on assessment, which is widely regarded as the driving force of learning, particularly in the programming context. Source code plagiarism emerged as a prevalent practice during the pandemic due to the challenges students face, including infrastructure limitations, learning in isolation, and the opportunities presented by online continuous assessment practices. Through an empirical study, the authors, as academics, investigated the occurrence of source code plagiarism during the COVID-19 lockdown period, along with the transition required to adjust to a post-COVID setting. The different theories that drive behaviour and decision-making in this context are analysed, and qualitative data is collected using open-ended questionnaires. Findings yield vital recommendations for the mitigation of source code plagiarism. Reflecting on the findings suggests that engaging students on source code plagiarism can assist in establishing shared norms, playing a positive role in reducing source code plagiarism. This is necessary, especially with the recent introduction of artificial intelligence tools such as ChatGPT, which may take source code plagiarism to a new level. Academics face long-term challenges and exciting opportunities in addressing source code plagiarism issues in the post-COVID context of integrating online and face-to-face modalities.
Student Learning Experiences and Well-Being during the COVID-19 Pandemic at the University of Free State
Authors: Pillay Semira , Lise Kriel  , Frank Magaya
Published: April 2024

South African universities were closed nationally during the COVID-19 pandemic. On-campus learning was suspended, and on-campus student accommodation was closed from March 2020, with phased returns to campus continuing until early 2022. The study intended to identify categories of students whose learning and well-being were most affected by the COVID-19 pandemic and provide empirical evidence to inform initiatives to support these students better. An online cross-sectional survey completed by 1 562 respondents studying at a South African university explored students’ experiences of the COVID-19 pandemic, focusing on students’ learning and well-being, subjective social status, sense of coherence, and future anxiety. Multivariable regression models showed younger age (18 to 21 years), female gender, low subjective social status, and isiZulu and English home language were significantly associated with lower well-being. Regression analysis also showed a significant association between the dimensions of manageability and meaningfulness of sense of coherence and well-being and that high levels of future anxiety were associated with lower well-being. Half of the respondents (49.6%) reported that the pandemic has negatively impacted their overall student experience. However, more than half (51.2%) prefer online to face-to-face learning and found it less time-consuming (63.5%). The results could assist universities in introducing appropriate support services targeting young female students with low subjective social status to support the mental health and well-being of those most affected by the pandemic
Mental Health Considerations in HIV Research Published in the South African Journal of Psychology, 2008–2018
Authors: Variava Tarique , Graham Tanya
Published: April 2024

In this study, we explore the themes related to mental health considerations in HIV/AIDS research published in the South African Journal of Psychology (SAJP) from January 2008 to December 2018. Utilising an exploratory research design, we purposively sampled 35 empirical articles from the SAJP to represent general trends. We conducted a thematic content analysis to identify recurring constructs and themes, following established guidelines. Key themes identified include the intersection between stigma, mental health and access to healthcare; the impact of HIV on cognitive functioning and performance; behavioural vulnerabilities and power dynamics; and challenges in healthcare service utilisation. The cumulative evidence from the SAJP highlights the need for targeted, culturally sensitive interventions that deal with systemic inefficiencies and stigma in the healthcare system. Interventions should also consider broader socio-economic factors and promote equitable relationships. In addition, it is vital to ensure that healthcare providers receive ongoing education on legal and ethical matters to aid in sound ethical decision-making. An all-encompassing, coordinated strategy is key to improving the lives of people living with HIV/AIDS in South Africa.

Authors: Hatupopi Saara , Nuumbosho Hellena , Amwaalanga Matride
Published: April 2024

Perinatal mental health guidelines are still lacking in more than 80% of low- and middle-income countries. World Health Organization has outlined the importance of an evidence-informed approach for developing and sustaining high-quality integrated mental health services for women during the perinatal period.

Method: The study explored healthcare providers' perceptions of implementing guidelines to manage perinatal depression in primary healthcare settings in Namibia. A qualitative, explorative, descriptive, and contextual design was applied to collect data from a purposively selected sample of 12 healthcare providers. This involved two focus groups with healthcare providers. Thematic analysis of the interview transcripts was conducted simultaneously with data collection.

Findings: The study highlighted three major themes for successfully implementing the guidelines to manage perinatal depression: the significance of implementing the guidelines, integration of the guidelines into perinatal care settings, and barriers to implementing the guidelines.

Conclusion: Healthcare providers were aware of poor maternal mental health provision within perinatal care settings and were ready to implement the guidelines to manage perinatal depression. Professional training and continuous education on perinatal depression are fundamental components in fostering quality of care and community awareness, as well as improving stigma within the community and healthcare providers.

This thesis aims to describe how tourism development in the Equator Bonjol Tourism Area, Pasaman Regency. This research is motivated by the small number of visitors who come to the Equator Bonjol Tourism Area, while this tourism has the potential and has become a leading tourism that will be a reference for the development of tourism in other tourist attractions in Pasaman Regency. In addition, Pasaman Regency in its RPJMD sets Pasaman Tourism Destinations as one of the priority programs. Therefore, researchers are interested in describing how tourism development in the Equator Bonjol Tourism area. The method used in this study is a qualitative descriptive method using interview, observation and documentation data collection techniques. Then to test the validity of the data obtained in the field, it is carried out using the source triangulation technique. As well as for the selection of informants, researchers use purposive sampling techniques. Based on research that has been conducted on tourism development in the Equator Bonjol Tourism Area, it can be concluded that broadly speaking these 4 core components already exist but have not been maximized because there are still some parts of these components that are not yet available. The available ones also cannot be developed optimally because the management carried out is not good enough. So that the development of the Equator Bonjol Tourism Area needs to be addressed further.

It can be concluded that the implementation of the Village-Owned Enterprises (BUMDes) Program Policy in Hulawa Village, Paguyaman Sub-district, Boalemo Regency, has not been implemented optimally following existing regulations. Several things still need to be improved, such as aspects of communication, resources,implementing attitude/disposition, and bureaucratic structure.
The Stress System of English Loanwords in Qassimi Arabic: An Optimality Theoretic Analysis
Authors: Alluhaidan Nuha Naser
Published: April 2024

The current paper examines the stress system of English loanwords as used by Qassimi Arabic (QA henceforth) speakers. It specifically conducts an optimality theory (OT) analysis of stress assignment of English borrowed words as uttered by QA speakers. The paper mainly seeks to investigate how stress is assigned in loanwords with different syllable types and syllable numbers, and how optimality accounts for it. The data in the paper are collected from previous studies as well as QA speakers. They are analyzed by the researcher using a number of markedness as well as alignment optimality constraints. It is found that stress assignment in English loanwords is adapted to the stress system of QA. Therefore, the ranking of OT constraints of borrowed English words is the same as that of original Qassimi Arabic words. The researcher concludes that QA stress system is well described and justified using the OT analysis.
Diff-Shape: A Novel Constrained Diffusion Model for Shape based De Novo Drug Design
Authors: Lin Jie , Xu Mingyuan , Chen Hongming
Published: April 2024

Shape-based virtual screening is a widely utilized method in ligand-based de novo drug design, aiming to identify molecules in chemical libraries that share similar 3D shapes but simultaneously possess novel 2D chemical structures compared to the reference compound. As an emerging technology, generative model is an alternative way to do de novo drug design by directly generating 3D novel structures. However, existing models face challenges in reliably generating valid drug-like molecules under specific conformation constrains. Here, a novel diffusion model constrained with 3D reference shape, Diff-Shape, was proposed to generate structures whose 3D conformations are similar to a given reference shape, thereby avoiding the computational cost of screening large database of 3D conformations. This model utilized a zero-weighted graph control module, taking in various forms of point clouds of reference shape to guide diffusion process of 3D molecular generation. The results show that our model is capable of generating molecules with high shape similarity but still low 2D graph similarity to the query structure and it significantly out-performs existing shape based generative models. Examples were also given to demonstrate that combining with docking software our model can effectively generate structures in structure-based drug design scenario.
The remnant of the midbody as a cellular signaling mechanism
Authors: Khripkov I.S. , Golikova A.A.
Published: April 2024

Cell signaling mechanisms are the basis for intercellular integration and regulation of proliferation and differentiation processes at the systemic level. One of the most plausible ways to control cell-to-cell interaction and targeted distribution of genetic information is for cells to use their own structures that are formed during mitosis and carry RNA-dependent signaling molecules that affect the mechanisms of control of intercellular interaction, cell proliferation and differentiation. The midbody remnant is a microtubule-rich structure that forms between dividing cells in the last stages of cytokinesis. Previously, it was thought to be only a temporary structure of the intercellular bridge during cytokinesis, which served to connect two future daughter cells. This structure is a key regulator of abscission and functions as a signaling platform that coordinates the cytoskeleton and endosomal dynamics during the terminal stages of cell division. The midbody is a subcellular structure that is formed during cell division, during penetration into the cleavage sulcus, when the microtubules of the central spindle are compacted and cross-linked by a thin intracellular bridge connecting the two daughter cells. The midbody plays a key role in organizing cytokinesis by recruiting a variety of mitotic kinases such as Aurora B and Plk1, as well as sulcus endosomes containing Rab11/FIP3, the membrane-rupturing ESCRT complex and the microtubule-rupturing enzyme spastin, all of which are responsible for mediated rupture during the later stages of cytokinesis. The midbodies can serve as extracellular and intracellular polarity signals during early embryogenesis, as well as during epithelialization and polarization of neurons. The molecular mechanism that governs the positioning of the middle body and how it transmits signals to neurons during differentiation or epithelium remains unknown. Importantly, the remains of the middle bodies can also function as intracellular signaling scaffolds that regulate proliferation and fate postmitotic cells. Since these structures can be released outside cells and taken up by other non-mitotic cells, it is suggested that they may function as vehicles for alternative transmission of complex sets of signaling molecules and/or receptors between cells, thus profoundly affecting signaling in general.

A Comparative Exploration of Gender Representations in Persian Sufi Literature and Modern Literary Works
Authors: Karımı Pune
Published: April 2024

The research examines how gender is depicted in Sufi and modern Persian literature, exploring the complex factors that influence the representation of gender roles and identities throughout different historical periods. The study meticulously reviews these literary genres to identify the many perspectives on gender, acknowledging that each genre provides a distinct viewpoint through which societal values are conveyed. The investigation delves into not just literary aesthetics but also the cultural and historical conditions that have shaped the development of gender norms. This study examines how Sufi and modern Persian literature, which are deeply influenced by their specific time periods and cultural contexts, mirror and distort social perspectives on gender. Through the analysis of the progression of these depictions over time, the study sheds light on the profound transformation of gender norms and identities throughout the course of Iranian history. This inquiry enhances our comprehension of the complex relationship between literature, culture, and gender dynamics, providing significant insights into how literary works reflect and influence society's perspectives. The results of this study not only enhance academic discussions on Persian literature but also offer a subtle perspective to analyze the wider cultural weave of Iran.
Müteahhir Dönem Hanefî Fakihlerinin Kurucu İmamlara Usulde Muhalefeti Mümkün Mü?: İbnü'l-Hümâm Özelinde Bir İnceleme
Authors: Şahin Ünal
Published: April 2024

Bu çalışmada Hanefî mezhebinin kurucu imamlarına müteahhir dönem mezhep fakihlerinin usul mesailinde muhalefet edip edemeyeceği hususu ele alınmıştır. Konu hakkında Hanefî mezhebinde genel kabul, kurucu imamlara usulde muhalefetin olmadığı yönündedir. Mezhepteki bu kabulün Sanayi Devrimi’ne kadar devam ettiğini söylemek mümkündür. Ancak sonraki dönemlerde meselenin farklı bir noktaya evrildiği müşahede edilmektedir. Bilhassa modern dönem çalışmalarında kurucu imamlara gerçek anlamda muhalefetin varlığı, sınırları ve keyfiyeti sorgulanmıştır. İbnü’l-Hümâm (ö. 861/1457) özelinde meseleye bakıldığında ise daha farklı bir tablo karşımıza çıkmaktadır. O, hicri 9’uncu asırda Mısır coğrafyasında yaşamış bir Hanefî fakihi olarak, farklı bir âlim prototipi ortaya koymakta ve usul meselelerinde içtihatta bulunmaktadır. Bu içtihatlar, mezhepte istikrar bulan ve kurucu imamların görüşlerini yansıtan metinlerden farklılık arz etmektedir. Onun, muhalefet ettiği konuların örf, âdet, zaman ve zemine göre değişen ayrıca, fetva mahiyetinde olmayan görüşlerden müteşekkil olduğunu da ifade etmek gerekmektedir. Bu kapsamda İbnü’l-Hümâm’ın usulî konularda mezhepteki yerleşik yaklaşımdan farklı görüşler ileri sürdüğü ve bunları temellendirmeye çalıştığı görülmektedir. Diğer taraftan İbnü’l-Hümâm’ın bu yönü, mezhep usulünden bütünüyle ayrılmadan tikel meselelerde içtihat faaliyetinin de devam ettiğinin açık delillerindendir. Buradan, mezhep ulemasının ilmî yetkinliğe ulaştığında fürû fıkıh bir tarafa usul mesailinde dahi içtihat ettiği anlaşılmaktadır. Bu içtihatların, farklı bir mezhep görüşünün tercihi olmadığı bilakis, delilden hareketle ulaşılan neticeler olduğu belirtilmelidir. Ayrıca onun Hanefî mezhebinde istikrar bulan yaklaşımdan ayrılan her bir farklı görüşü, içtihat merkezli olmayıp bazen konu hakkında tercih olabilmektedir. Bundan dolayı bu gibi farklılıkların içtihat mı yoksa tercih mi olduğunun iyice tetkik edilmesi gerekmektedir.

Published: April 2024

In this paper, we introduce the concept of a parapseudo-complementation in a paradistributive latticoid(PDL) and investigate its elementary properties. We demonstrate the independence of the axioms related to its definition, highlighting the flexibility of this concept. Additionally, we establish necessary conditions for a PDL with a minimal element to be parapseudo-complemented and explore the properties required for parapseudo-complementation to be equationally definable. Moreover, we establish a one-to one correspondence between the set of all minimal elements and the set of all parapseudo-complementations.
Extending Abelian Rings: A Generalized Approach
Authors: Saad Muhammad , Zailaee Majed
Published: April 2024

We introduce a novel framework for assessing the centrality of idempotents within a ring by presenting a general concept that assigns a degree of centrality. This approach aligns with the previously established notions of semicentral and q-central idempotents by Birkenmeier and Lam. Specifically, we define an idempotent $e$ in a ring $R$ to be $n$-central, where $n$ is a positive integer, if $[e, R]^ne=0$, where $[x,y]$ represents the additive commutator $xy-yx$. If every idempotent in a ring $R$ is $n$-central, we refer to $R$ as $n$-Abelian. Our study lays the groundwork by presenting foundational results that support this concept and examines key features of $n$-central idempotents essential for appropriately categorizing $n$-Abelian rings among various generalizations of Abelian rings introduced in prior literature. We provide examples of $n$-central idempotents that do not fall under the categories of semicentral or $q$-central. Furthermore, we demonstrate that the ring of upper matrices $\mathbb{T}_n(R)$, where $R$ is Abelian, is an $n$-abelian. We also prove that a ring where all of its idempotents are $n$-central is an exchange ring if and only if the ring is clean.

Let $G\neq \overline{K}_n$ be a graph with vertex and edge-sets $V(G)$ and $E(G)$, respectively. Then\linebreak $O$ $\subseteq$ $V(G)$ is called a J-open independent set of $G$ if for every $a,b \in V(G)$ where $a\neq b$, $d_G(a,b)$ $\neq 1$, and $N_G(a) \backslash N_G(b) \neq \varnothing$ and $N_G(b)\backslash N_G(a) \neq \varnothing$. The maximum cardinality of a J-open independent set of G, denoted by $\alpha_J(G)$, is called the J-open independence number of $G$. In this paper, we introduce new independence parameter called J-open independence. We show that this parameter is always less than or equal to the standard independence (resp. J-total domination) parameter of a graph. In fact, their differences can be made arbitrarily large. In addition, we show that J-open independence parameter is incomparable with hop independence parameter. Moreover, we derive some formulas and bounds of the parameter for some classes of graphs and the join of two graphs.

Published: April 2024

For each $\alpha$-ideal of an almost distributive lattice (ADL) to become a $\sigma$-ideal, a set of equivalent conditions is derived, which tends to result in a characterization of generalized Stone ADLs.  On an ADL, a one-to-one correspondence is derived between the set of all prime $\sigma$-ideals of the ADL and the set of all prime $\sigma$-ideals of the quotient ADL. Finally, proved some properties of prime $\sigma$-ideals of a normal ADL topologically.

The Volterra-type composition operators induced by the maps $g$ and $\varphi$ are defined as  $$\left(I_{g}^{\varphi}f\right)(z)= \int_{0}^{z} f^{\prime}(\varphi(\zeta)) g(\zeta) d\zeta  \hspace{0.07in} \text{and} \hspace{0.07in}  \left(T_{g}^{\varphi}f\right)(z)= \int_{0}^{z} f(\varphi(\zeta)) g^{\prime}(\zeta) d\zeta .$$For $1\leq p<\infty$, $S^p(\mathbb{D})$ is the space of all analytic functions on $\mathbb{D}$ whose first derivative $f^{\prime}$ lies in the Hardy space $H^p(\mathbb{D})$, endowed with the norm $\displaystyle \|f\|_{S^p}=|f(0)|+\|f^{\prime}\|_{H^p}$. Let $\mu: (0,1] \rightarrow (0, \infty)$ be a positive continuous function on $\mathbb{D}$ such that for $z\in\mathbb{D}$ we define $\mu(z) = \mu(|z|)$. The weighted Zygmund space  $\mathcal{Z}_{\mu}(\mathbb{D})$ is the space of all analytic functions $f$ on $\mathbb{D}$ such that $\sup_{z\in \mathbb{D}} \mu(z) |f^{\prime\prime}(z)|$ is finite. In this paper, we characterize the boundedness and compactness of the Volterra-type composition operators that act between $S^p$ spaces and weighted Zygmund spaces.
Analysis and Applications of the Chaotic Hyperbolic Memristor Model with Fractional Order Derivative
Authors: Ahmed Ghada
Published: April 2024

This work presents a new five-dimensional fractional-order chaotic system that includes a feedback memristor. A Lorenz-Stenflo-based fractional-order chaotic system with five dimensions that contains feedback memristor dynamics is used to do this. This work focuses on chaotic models through the ABC fractional derivative, a concept we rigorously examine. We designed and usedsophisticated numerical algorithms to model fractional-order dynamics with the utmost precision to understand this system’s complex characteristics. These numerical approaches excel at non-integer order differentiation, which standard numerical methods struggle with. Our research uses fractional calculus to increase the system’s complexity and robustness, revealing its hyperchaotic nature. We demonstrate that the system is chaotic and stable over fractional orders using eigenvalues, Lyapunov exponents, Kaplan-Yorke dimensions, maximal exponents, phase portraits, and equilibrium points. Our conclusions are strengthened by using these numerical systems, intended for this work, and analytical tools. We improve our understanding of fractional-order chaotic systems with our research. It illuminates how to improve electrical integrations and create more sophisticated nonlinear dynamical systems. This work establishes the approach and insights for future research, guiding the development of new systems with enhanced dynamical features

Published: April 2024

This work pioneers a novel approach in image edge detection through the utilization of the generalized fractional operator. By harnessing the global attributes inherent in fractional derivatives, it aims to enhance the extraction of intricate edge details.This is accomplished by creating the mask by using fractional derivative and adapt the mask by another parameter, yielding compelling and informative edge representations, as validated by experimental results. This advancement not only augments computer vision and image analysis techniques but also holds promise for refining image processing methodologies. Future endeavors may explore its adaptability across diverse imaging domains like medical and satellite imagery, while integration into deep learning frameworks could elevate its potential for advanced feature extraction and deeper image understanding. Additionally, optimizing its computational efficiency would broaden its scope for real-time deployment in fields such as robotics and autonomous systems.

Published: April 2024

In this paper, we establish the existence of a common fixed point from a pair of set-valued mappings. By utilizing the concept of convergence of set-valued mappings' sequences, both ordinary and pointwise convergence, we establish a common fixed point theorem. This our newly result is a generalization of common fixed point theorem of set-valued mappings on partial metric spaces. Further, we establish newly common fixed point theorem under $\phi$-contraction on partial metric spaces.

Human beings are a social animal and we progress through communication by using language. Effective communication is needed in our day to day lives and in order to communicate effectively it is significant to attain the language domain effectively as well. Language domain is a communication skill, it is the ability to listen, speak, read and write. The improvement of the four language domains can enable an individual to develop proficiency in Tenyidie. The effective communication depends on the level of how well an individual can use a language accurately and aptly. One cannot become proficient or master a language by overnight rather it is through practice and proper learning of language skills one can attain the desired proficiency in Tenyidie language. This paper aims to discuss the primacy and importance of the language domains and bring out suggestive measures towards improving language skills straddled with the intent to motivate learners to acquire proficiency in Tenyidie language.
Money Supply, Inflation and Dollarization: An Analysis on Türkiye Using Fourier Models
Authors: Alpağut Serhat
Published: April 2024

This study examines the impact of inflation and money supply on dollarization. Especially in recent years, the rapid rise of the exchange rate and inflation in Türkiye has put the phenomenon of dollarization back on the agenda. The study covers the period 2012Q4-2023Q4. The study first applies the Fourier ADL cointegration test, which allows for soft breaks. As a result of the test, it was found that the variables have a long run relationship. In the short run, only budget revenue has a positive effect on dollarization. In the long run, the exchange rate, exports, money supply, and deposit rates have a positive effect, while inflation has a negative effect. The study also applied the Fourier-Toda-Yamamoto causality test. As a result of the test, bidirectional causality was found between exchange rate, inflation and money supply variables and dollarization. The striking result of the study is that inflation has a negative impact on dollarization. This result, which is consistent with some studies in the literature, is attributed to the money supply. Although the demand for foreign exchange increases because the money supply is higher than inflation, the dollarization index decreases. This explanation can explain the negative relationship.

Authors: Özekenci Emre Kadir
Published: April 2024

International Market Selection (IMS) is crucial for companies seeking growth and expansion beyond their domestic boundaries. IMS is a strategic decision that requires careful evaluation of several factors to minimize risks and achieve long-term success in international markets. Accordingly, this study aims to find out optimal market alternatives for exporter companies operated in iron and steel sector. A total of twenty-three market alternatives were evaluated based on ten criteria. The alternatives and criteria were determined by literature review and expert opinions. The weight of criteria was calculated by the FUCOM and LOPCOW methods. Once the weight of criteria was determined, the alternatives were ranked using the SPOTIS, RSMVC, CoCoSo and Borda Count methods. The results showed that balance of trade and GDP were the most and least important criteria, respectively. Overall results revealed that Canada, the UAE, Germany, Japan and Malaysia were the best market alternatives, while Venezuela, Mexico, Peru, Colombia and the UK were the worst market alternatives for iron and steel exporter companies. Additionally, the sensitivity analysis was carried out to observe the robustness of the results.
