 Abstract

The implementation of a Massive MIMO-based 6G communication system with Full Duplex (FD) and Half Duplex (HD) aims to enhance spectral efficiency and network capacity while addressing self-interference challenges. The project is executed in two phases: first, implementing FD with and without Self-Interference Cancellation (SIC) and Reconfigurable Intelligent Surfaces (RIS); second, comparing FD with HD in terms of spectral efficiency, interference management, and overall system performance. SIC techniques, including digital and analog cancellation, are employed to mitigate self-interference in FD systems, enabling simultaneous transmission and reception on the same frequency band. Key performance metrics such as Signal-to-Noise Ratio (SNR), Bit Error Rate (BER), Mean Square Error (MSE), and data rates are analyzed using MATLAB to compare FD with SIC and RIS against traditional HD systems. The results demonstrate that FD, when integrated with SIC and RIS, significantly improves spectral efficiency and data throughput while reducing latency, making it a promising technology for next-generation 6G networks.

 Abstract

Chronic diseases such as diabetes, cardiovascular conditions, and respiratory illnesses represent some of the most persistent and resource-intensive challenges in modern healthcare. With the increasing global burden of these conditions, the healthcare industry is turning to digital technologies for sustainable solutions. This paper explores the integration of wearable technology and artificial intelligence (AI) as a transformative approach to managing chronic diseases. Wearables, equipped with sensors and connectivity features, continuously collect real-time physiological data such as heart rate, glucose levels, and physical activity. When combined with AI-driven analytics, this data becomes a powerful tool for early detection, personalized treatment, and continuous monitoring. The paper examines the core technologies underpinning wearable-AI synergy, reviews current applications across chronic disease domains, and evaluates ethical, regulatory, and operational considerations. Additionally, it outlines challenges such as data fragmentation, user adherence, and algorithmic transparency. Future innovations like federated learning, smart fabrics, and explainable AI hold immense promise in improving the scalability and reliability of these systems. Through a comprehensive analysis, this study underscores how wearable and AI integration can revolutionize chronic disease care, shifting healthcare from reactive treatment to proactive, data-driven intervention.

 Abstract

An autoimmune response against two hemidesmosomal proteins in the dermal-epidermal junction, BP180 and BP230, is the characteristic of bullous pemphigoid (BP), a blistering dermatosis. BP180 is an extracellular domain-bearing transmembrane glycoprotein, while BP230 is intracellularly bound and associated with the hemidesmosomal plaque. Most BP patients possess autoantibodies that bind to the noncollagenous 16A domain (NC16A) of BP180, an immunodominant region of BP180 that is extracellularly located adjacent to the protein's transmembrane domain. Autoreactive T and B cell responses to BP180 in BP patients have been reported. In mice, a bullous skin disease with a very close analog of human blood pressure is induced by passive antibody transfer to the mouse BP180 ectodomain. In this model of animals, the formation of lesions relies on mast cell degranulation, complement activation, and neutrophil and eosinophil recruitment. Dermal-epidermal separation occurs in cryosections of human skin when autoantibodies against BP180 are co-incubated with leukocytes. Granulocytes secrete proteinases that cause loss of cell-matrix adhesion. The development of new treatment strategies for BP may be facilitated by our increasing knowledge of its pathophysiology.

 Abstract

Artificial intelligence (AI) is revolutionizing drug discovery, accelerating the identification of novel therapeutics and redefining pharmaceutical research. As we approach 2025, AI-driven innovations particularly generative AI and advanced data analytics are not only expediting drug development but also enabling precision medicine and reducing costs. This transformation is fueled by deep learning models capable of designing entirely new molecular structures, predictive analytics that optimize clinical trials, and federated learning that enhances collaborative drug discovery while maintaining data privacy.

 Abstract

Hybrid neural-fuzzy systems are used for gender estimation of dental panoramic radiographs, coupling methods such as convolutional neural net- works (CNNs), fuzzy logic, and contrast-limited adaptive histogram equaliza- tion. Stratified cross-validation is performed for analysis after pre-processing on a dataset comprising 947 images. The most successful approach of SVM augmented using expanded fuzzy rules comes with accuracy rating of 94.93% and finds a better success than traditional models. Results highlight the mer- its of hybrid strategies in maintaining accuracy and interpretability in dental diagnostics and forensic purposes.

 Abstract

Customer satisfaction is a critical factor in the e-commerce industry that affects consumer behaviour, brand loyalty, and market dynamics. This study looked at the main factors influencing customer satisfaction, including customer service, return and refund policies, delivery speed, and product quality. This study provides a thorough analysis of consumer expectations and experiences with online shopping by comparing survey data from 148 participants with previous research. According to the findings, customer satisfaction was largely dependent on delivery speed (39.5%) and product quality (46.7%). Even though e-commerce platform satisfaction is generally moderate (3.5/5), problems with payment security (18.9%) and return/refund procedures (26.8%) still exist. Additionally, 34.2% of respondents said they were unhappy with the customer service they received. The knowledge gained from this study will help businesses improve their plans to satisfy evolving consumer needs.
