Authors: Shurrab Saeed , Shannak Yazan , Duwairi Rehab
Published: April 2023

Retina disorders are among the common types of eye disease that occur due to several reasons such as aging, diabetes and premature born. Besides, Optical Coherence Tomography (OCT) is a medical imaging method that serves as a vehicle for capturing volumetric scans of the human eye retina for diagnoses purposes. This research compared two pretraining approaches including Self-Supervised Learning (SSL) and Transfer Learning (TL) to train ResNet34 neural architecture aiming at building computer aided diagnoses tool for retina disorders recognition. In addition, the research methodology employs convolutional auto-encoder model as a generative SSL pretraining method. The research efforts are implemented on a dataset that contains 109,309 retina OCT images with three medical conditions including Choroidal Neovascularization (CNV), Diabetic Macular Edema (DME), DRUSEN as well as NORMAL condition. The research outcomes showed better performance in terms of overall accuracy, sensitivity and specificity, namely, 95.2%, 95.2% and 98.4% respectively for SSL ResNet34 in comparison to scores of 90.7%, 90.7% and 96.9% respectively for TL ResNet34. In addition, SSL pretraining approach showed significant reduction in the number of epochs required for training in comparison to both TL pretraining as well as the previous research performed on the same dataset with comparable performance.

(2) To investigate factors related to the level of knowledge and behavior of foot care in patients with diabetes. Methodology: Cross-sectional description on 108 patients diagnosed with diabetes according to ADA 2021 criteria. The study used questionnaires (Modified Diabetes Foot Care Knowledge - MDFCK) to assess knowledge of diabetic foot care and questionnaires (Modified Foot Care Behavior - MDFCB) to assess diabetic foot care behavior. Results: the diabetic foot care knowledge score was at a poor level (mean
score 6.33 ± 2.8) of which 13.9% of them had good knowledge, 32.4% had moderate and 52.7% had poor knowledge. Diabetic foot care behaviors were at poor level (mean 54.36 ± 8.4) of which 64.8% had poor behaviors and 35.2% had moderate behaviors. Low education, time of diabetes for < 5 years and no previous diabetes foot care instructions were predictive factors for poor MDFCK and MDFCB. Good knowledge of diabetic foot care can lead to good caring behavior. Age ≥ 65 has no effect on MDFCB but has a negative effect on MDFCK. Conclusion: the diabetic foot care knowledge score and diabetic foot care behavior score were poor. Health education counseling programs based on relevant factors should be provided to improve the self-care capacity of people with diabetes.

Authors: Kozachuk O. S. , Vorontsova L. L. , Kovalenko V. A.
Published: April 2023

The aim. Study of the state of the cellular link of nonspecific immunity depending on the type and amount of alcohol consumed.

Materials and methods. 110 men between the ages of 20 and 55 were examined, who were divided into 3 groups. The first (control) group consisted of 17 fertile men who do not drink alcoholic beverages. The second group (comparison) consisted of 27 patients who use, but do not abuse, all types of alcoholic beverages (1-2 doses of alcohol approximately once every 1-3 months). The third group consisted of 66 patients who abuse alcoholic beverages (6 or more units of alcohol at a time or 22 or more doses per week). Depending on the type of alcohol, this group was divided into 3 subgroups: 3a subgroup – 13 patients who abuse strong alcoholic beverages; 3b - 27 patients who abuse beer and 3c group - 26 patients who abuse beer and strong alcoholic beverages. All men underwent a survey to assess alcohol consumption during the past year, as well as an assessment of the phagocytic activity of the neutrophilic and monocyte units of the immune system with the calculation of the degree of immune system disorders.

The results of the conducted studies showed that incomplete phagocytosis of neutrophilic and monocyte links was observed in all studied groups with preservation of the functional-metabolic reserve in groups 2 and 3a and its depletion in groups 3b and 3c. The most immunologically compromised were groups 3b and 3c, in which 1-2 degree deficiency was observed, which perhaps reflects the negative effect of beer itself on the cellular factors of innate immunity.

Conclusion. Consumption of both strong alcoholic beverages and beer causes suppression of the phagocytic activity of neutrophils and stimulation of the absorption capacity of monocytes, which is manifested by ineffective phagocytosis. With the consumption of strong alcoholic beverages, preservation of the functional and metabolic reserve of neutrophils is observed, and with the consumption of beer and mixed alcoholic beverages, its deficiency is observed.

Preprocessing Impact Analysis for Machine Learning-Based Network Intrusion Detection
Authors: GÜNEY Hüseyin
Published: April 2023

Machine learning (ML) has been frequently used to build intelligent systems in many problem domains, including cybersecurity. For malicious network activity detection, ML-based intrusion detection systems (IDSs) are promising due to their ability to classify attacks autonomously after learning process. However, this is a challenging task due to the vast number of available methods in the current literature, including ML classification algorithms and preprocessing techniques. For analysis the impact of preprocessing techniques on the ML algorithm, this study has conducted extensive experiments, using support vector machines (SVM), the classifier and the FS technique, several normalisation techniques, and a grid-search classifier optimisation algorithm. These methods were sequentially tested on three publicly available network intrusion datasets, NSL-KDD, UNSW-NB15, and CICIDS2017. Subsequently, the results were analysed to investigate the impact of each model and to extract the insights for building intelligent and efficient IDS. The results exhibited that data preprocessing significantly improves classification performance and log-scaling normalisation outperformed other techniques for intrusion detection datasets. Additionally, the results suggested that the embedded SVM-FS is accurate and classifier optimisation can improve performance of classifier-dependent FS techniques. However, feature selection in classifier optimisation is a critical problem that must be addressed. In conclusion, this study provides insights for building ML-based NIDS by revealing important information about data preprocessing.

Palestinian Novel & Modes of Oral Narration: al-Wārith (The Heir), a Novel by Khalīl Baydas as a Model
Authors:   Birzeit University, Palestine, Khoury Mousa
Published: April 2023

This research studies al-Wārith, a novel by the Palestinian novelist Khalīl Baydas published in 1920. The introduction points at the consequences of the absence of the novel from critical studies for a long time until it was re-published in 2011, and hints at other studies that are mainly dependent on Dr. Nāsir al-Dīn al-Asad’s summary of the novel, and consequently, on his comments and interpretations. In its first section, the research deals with al-Asad’s study of the novel, and uncovers its recurrent impact on latter studies. Then, it proposes another interpretation based on the fact that the Palestinian society, at the turn of the twentieth century, was an oral one, or in its best conditions, an oral society impregnated with writing. In its second section, the research introduces a theoretical framework on which this different interpretation is based which comes in two parts. The first part discusses Baydas’ theoretical concepts of the novel/story and its implied reader, and brings to attention the overall circumstances during which al-Wārith emerged. The second part exhibits the various distinctive features/modes of oral production. In its third section, the research transforms these oral features into thier applicable sphere by following their appearance in the novel; thus, explaining Baydas’ concepts and the critics’ repetitive comments. Finally, the research concludes that al-Wārith did not totally divert from the modes of oral narration and the controls of its production that were absent from studies concerned with Palestinian literature at the beginning of the last century.
Representations of Reality in the Play "The Return of Cain" by the Egyptian Writer Sadia al-Adly
Authors:   Department of Arabic Language and Literature, Taif University, Elaasar Mohamed
Published: April 2023

The research seeks to uncover the social issues and phenomena that have occurred in the Egyptian society in the last ten years due to many factors that have changed its features and disrupted its culture as they are depicted in the play "The Return of Cain" by the Egyptian writer Saadia al-Adly. The study tries to reveal those issues in the Play and to determine their implications. Among the important issues and phenomena that the Egyptian society suffers from and Saadia al-Adly has incorporated in her play are family division, material tyranny, religious ignorance, rejection of terrorism, psychological breakdown, and self-loathing. These phenomena were not common before in the Egyptian society, and they had a negative impact on the community and its safety, especially the city community as it is the most vulnerable to the rapid changes. The importance of this theatrical text comes as a reflection of the reality of society, and an expression of a crisis reality that imposes on the recipient to raise awareness of it and its concerns and issues, and to create a state of transgression in the theatrical text through which it seeks to preserve the remaining customs, traditions and authentic constants in the face of issues of material reality and its negatives through spreading the values of peace, family and community coexistence, and national belonging.

About Some Terms of Regional Linguistics
Authors: Maximchuk Nina
Published: April 2023

The article discusses the problems of terminology of the scientific direction developing within the framework of modern humanitarian knowledge – regional linguistics. The integrative nature of regional linguistics (its relationship with geography, history, ethnography, dialectology, sociolinguistics, etc.) not

only forms the specifics of this discipline, the variety of terminological nominations of its key concepts and their interpretations, but also determines the multivector approaches to solving its main tasks. Within the framework of the proposed

approach, based on the analysis of the scope of the concept of region, considered as a field structure, the external boundaries of the derived terminological nominations are clarified – regiolect, regional worldview and regional linguistic personality. The latter, in turn, are characterized against the background of universal concepts of the world picture and linguistic personality. The specifics of correlation relations between the concepts of regional linguistic personality and regional worldview are determined. The role and place of regional knowledge in the structure is characterized.
An Improved Proactive Handoff Scheme (IPHS) for Target Channel Selection in Cognitive Radio Network
Authors: Orokpo James Audu , Tekanyi A M.S , Abdulkareem H A , Agbon Ezekiel E
Published: April 2023

In recent years, one of the challenges of spectrum allocation and utilization was fixed spectrum allocation which lead to spectrum scarcity and underutilization. In an attempt to address this challenge, Cognitive Radio Network (CRN) which uses Dynamic Spectrum Access (DSA) was proposed. It allows licensed users’ or Primary Users’ (PUs) spectrum to be shared with unlicensed users or Secondary Users (SUs). DSA could be achieved by developing an effective channel selection scheme for SUs spectrum handoff. Selecting an appropriate channel for the SUs to continue their interrupted transmission is a challenging task. Several researchers have used different techniques such as Novel Proactive Handoff Scheme (NPHS) to enhance accurate channel selection for spectrum handoff by considering only channel occupancy. These techniques still suffer some set back like high number of spectrum handoff and delay in channel selection. This paper presents an Improved Proactive Spectrum Handoff Scheme (IPHS) for accurate target channel selection in CRN. The improvement is achieved by considering channel signal quality in addition to channel occupancy as a criteria for the selection of a backup channel for spectrum handoff. Simulation results showed that the IPHS reduced the number of spectrum handoff by 15% and 26% as compared to NPHS and IEEE 802.11 scheme respectively. The average delay was also reduced by 13% and 35% as compared to NPHS and IEEE 802.11 scheme respectively.
Study on Electron Tunneling Lifetime by Projected Green’s Function Approach in Single Quantum Well Semiconductor
Authors: Sarwono Yanoar Pribadi , Zhang Rui-Qin , Sunnardianto Gagus Ketut
Published: April 2023

The tunnelling lifetime of an electron in a single quantum well subject to an externally applied electric field is calculated using the Projected Green’s Function (PGF) approach. The lifetime in the biased single well decreases as a function of the electric field in good agreement with the previous result. The tunnelling lifetime is revealed with the behavior of the ground-state shift and the wave amplitude in the first well. As the electric field increases, the ground state energy shifts, leading to lessened constructive interference between the initial and reflected electron waves. Consequently, the study is essential to characterize the performance of high-speed quantum devices.

Published: April 2023

Feedback-controlled electromigration (FCE) is employed to control metal nanowires with quantized conductance and create atomic junctions. The FCE scheme is commonly implemented using many experimental parameters, and determining the optimal FCE parameters can be regarded as a combinatorial optimization problem. The D-Wave quantum annealer has attracted attention for its hardware implementation of quantum annealing (QA), which is a heuristic algorithm for solving combinatorial optimization problems. This study developed a QA approach for optimizing the FCE parameters and executed it on a quantum annealer. The results and performance were compared with those of a classical solver.

Published: April 2023

Chronic diseases, such as diabetes, hypertension, and heart disease, are a growing public health concern globally. The burden of these diseases on healthcare systems and patients is enormous. To address these challenges, innovative technologies, such as chatbots, have emerged as promising solutions to improve chronic disease management. Chatbots are artificial intelligence (AI) programs that can simulate conversations with humans and provide personalized and cost-effective care. This research paper aims to explore the key use cases for chatbots in chronic disease management, such as personalized education, symptom monitoring, medication management, and lifestyle coaching. Furthermore, it discusses the potential benefits and challenges of chatbots in chronic disease management, including patient engagement, data privacy, and the need for human oversight. Finally, the paper concludes that chatbots have the potential to transform chronic disease management by providing personalized and cost-effective care, but their integration into healthcare systems requires careful consideration of ethical, legal, and regulatory frameworks.

Malware for Android is becoming increasingly dangerous to the safety of mobile devices and the data they hold. Although machine learning techniques have been shown to be effective at detecting malware for Android, a comprehensive analysis of the methods used is required. We review the current state of Android malware detection using machine learning in this paper. We begin by providing an overview of Android malware and the security issues it causes. Then, we look at the various supervised, unsupervised, and deep learning machine learning approaches that have been utilized for Android malware detection. Additionally, we present a comparison of the performance of various Android malware detection methods and talk about the performance evaluation metrics that are utilized to evaluate their efficacy. Finally, we draw attention to the drawbacks and difficulties of the methods that are currently in use and suggest possible future directions for research in this area. In addition to providing insights into the current state of Android malware detection using machine learning, our review provides a comprehensive overview of the subject.
Time-Optimal Model Predictive Control of Permanent Magnet Synchronous Motors in the Whole Speed and Modulation Range Considering Current and Torque Constraints
Authors: Brosch Anian , Wallscheid Oliver , Böcker Joachim
Published: April 2023

Improving control dynamics and enabling maximum torque and power conversion for a given electrical drive are important target quantities of drive control algorithms. To utilize the electrical drive to its maximum extent during transient and steady-state operation, a time-optimal continuous-control-set model predictive flux control (CCS-MPFC) for permanent magnet synchronous motors (PMSM) is proposed. This scheme considers torque and current limits as softened state constraints in the CCS-MPFC’s optimization problem to prevent transient overcurrents as well as torque over- and undershoots during time-optimal operating point changes. Furthermore, the overmodulation range including six-step operation can be entered seamlessly to ensure maximum power conversion at high speeds. Fastest transients within the whole modulation range are enabled by a time-optimal harmonic reference generator (TO-HRG). Here, the flux reference of the CCS-MPFC is complemented with a harmonic content that enables operation in the overmodulation region. Further, the reference is pre-rotated during transient operation to attain time-optimal control performance. Extensive simulative as well as experimental investigations for linearly and nonlinearly magnetized PMSMs show that, compared to state-of-the-art methods, time-optimal control performance in the whole modulation range without transient overcurrents as well as torque over- and undershoots can be achieved by the proposed control method.

Toward Network Slicing Enabled Edge Computing: A Cloud-Native Approach for Slice Mobility
Authors: Shah Syed Danial Ali , Gregory Mark A , Li Shuo
Published: April 2023

Network slicing is a key enabler for 5G and beyond networks that permits operators to provide scalable, flexible, and dedicated networks over a common physical infrastructure. To cope with the rising demand for Ultra-Reliable and Low-Latency Communication (URLLC) in beyond 5G networks, the provision of dedicated secure networks closer to the users is essential. Multi-access Edge Computing (MEC) is a promising technology that provides data and computational resources closer to mobile users. However, MEC servers are resource-constrained, and offering dedicated service-specific network slices at the edge in a highly dynamic and mobile environment is challenging. Network slicing and MEC are being evolved by two different standardization bodies that limit their integration and raise mobility challenges that deserve more attention. We propose a cloud-native microservices architecture for network slice mobility management in MEC that permits each MEC slice to be distributed as stateless and independently deployable microservices. The proposal separates the MEC slice operational data and the user context, as each network function in an MEC slice stores the context in a separate shared database. The proposed architecture leverages new SDN extended federation modules in compliance with the ETSI requirements for inter-MEC system coordination. The federation modules support a more flexible and scalable creation of network slices at MEC servers, efficient resource utilization, and mobility of network slices across MEC servers. The simulation results show that our proposed architecture outperforms the existing SDN-based approaches for network slicing in MEC by achieving high slice acceptance rates and reduced slice migration delay.

Spatiotemporal Dynamics and Frame Features for Improved Input Selection in Video Super-Resolution Models
Authors: Agrahari Baniya Arbind , Lee Glory , Eklund Peter , Aryal Sunil
Published: April 2023

This paper presents a novel approach to video super-resolution (VSR) by focusing on the selection of input frames, a process critical to VSR. VSR methods typically rely on deep learning techniques, those that are able to learn features from a large dataset of low-resolution (LR) and corresponding high-resolution (HR) videos and generate high-quality HR frames from any new LR input frames using the learned features. However, these methods often use as input the immediate neighbouring frames to a given target frame without considering the importance and dynamics of the frames across the temporal dimension of a video. This work aims to address the limitations of the conventional sliding-window mechanisms by developing input frame selection algorithms. By dynamically selecting the most representative neighbouring frames based on content-aware selection measures, our proposed algorithms enable VSR models to extract more informative and accurate features that are better aligned with the target frame, leading to improved performance and higher-quality HR frames. Through an empirical study, we demonstrate that the proposed dynamic content-aware selection mechanism improves super-resolution results without any additional architectural overhead, offering a counter-intuitive yet effective alternative to the long-established trend of increasing architectural complexity to improve VSR results.
