Within the current VUCA technological environment, manufacturing industry in emerging countries faces serious challenges, such as disengagement of employees, increased stress levels, and high turnover rate. Even though artificial intelligence (AI) is increasingly being incorporated into work processes, little research has been conducted on AI and its impact on the emotional reactions of employees. Thus, this research fills this gap by using outside-in perspective to investigate the impact of ...
Copper is highly vulnerable to degradation in corrosive environments, necessitating effective surface protection strategies. In this study, nickel coatings were electrodeposited onto copper substrates to improve their properties. However, the as-deposited coatings exhibited inadequate adhesion with surface defects, indicating the need for an additional post-treatment. To overcome this limitation, a surface mechanical treatment through conventional shot peening (CSP) was employed to refine the...
Non-incremental clustering algorithms (NICLAs) dealing with dynamic data suffer from issues related to their compute-intensive behaviour. A plausible approach to address these issues lie in transforming the NICLAs into intelligent (incremental) methods that are capable of processing dynamic data. MBSCAN is one such robust NICLA that leverages the idea of data-dependent dissimilarity to find clusters. An incremental version of MBSCAN namely ππππ π was designed to handle single-point inser...
This paper presents a comprehensive study of advanced techniques for designing digitally coded metasurfaces, highlighting their ability to manipulate electromagnetic wave propagation. Five key methodologies are investigated and compared: Back Projection (BP), Genetic Algorithm (GA), Particle Swarm Optimization (PSO), Superposition, and Deep Learning (DL). While the computationally efficient BP method is suitable for single-beam configurations, it is inadequate for multi-beam or complex radiat...

With the increasing incidence of multidrug-resistant (MDR) bacterial infections and aggressive cancers such as cholangiocarcinoma, the present study aimed to evaluate the phytochemical composition, antibacterial activity, and anticancer potential of C. thevetia leaf and flower extracts. Ethanolic and aqueous extra...
Mangrove ecosystems are a foundational pillar of the emerging blue economy. However, environmental stressors such as salinity fluctuations, pollution, and climate change threaten mangrove survival and regeneration. This study aim to evaluate the role of a synergistic polymicrobial bacterial-fungal inoculum as a blue biotechnology strategy to promote seed germination and enhance the growth of Avicennia officinalis L.. Amplicon-based metagenomic analysis revealed 1,372 bacterial and 2...
Underwater images suffer from unique challenges during restoration, due to absorption and scattering of light. It results in significant loss of fine details, color cast, blurriness, and irregular haze. Existing methods struggle to capture the fine details in complex underwater scenarios. To tackle these difficulties, we propose a novel Edge-guided Feature Refinement (EFR) module using channel attention and integrate this in a vision transformer based architecture. It is precisely designed to...
Different machine learning (ML) models are used in various engineering applications for prediction purposes. The performance of ML models is often governed by their hyperparameters. Support vector regression (SVR) is a widely accepted ML model for predicting transportation costs across various engineering fields, as it can learn non-linear relationships with the help of a kernel, even with small to medium-sized datasets. Therefore, the present work uses SVR to model transportation cost in the...

Phenylketonuria (PKU) is an inherited metabolic disorder caused by deficiency of phenylalanine hydroxylase, resulting in excessive accumulation of phenylalanine inside the body. Accumulation of it shows metabolic and cytotoxicity, high concentration of phenylalanine undergoes spontaneous self-assembly under physiological conditions, forming ordered amyloid-like aggregates stabilized by aromatic ΟβΟ interactions, hydrogen bonding, and hydrophobic forces, with fibrillary morphology similar to p...
The precise estimation of active earth pressure (AEP) in retaining walls supporting unsaturated backfills continues to be a major challenge in geotechnical engineering. Classical theories mostly consider dry or fully saturated soils, thus, neglecting the development of the tensile stress zones under partial saturation conditions [1], [2]. Such conditions eventually give rise to tension cracks, which further, alter the lateral stress field and thus, affecting the global stability of retaining ...

Cancer is a leading cause of mortality worldwide, with brain cancers accounting for approximately 3% of all reported cases. Glioblastoma is the most aggressive and treatment-resistant form of brain cancer, necessitating the development of novel therapeutic strategies. Berberine, a naturally occurring isoquinoline alkaloid derived from plants of the Berberidaceae family, has demonstrated significant anticancer potential due to its low toxicity and ability to cross the blood-brain barrier. In t...
Fossil fuel reserves are rapidly depleting and the burning of conventional fuels releases large amounts of carbon dioxide into the atmosphere. Crops which are rich in sugar and starch are the best biomass for conversion to ethanol. However, most of them are edible crops and this competes with their use as food. One promising alternative is bioethanol production from seaweed. One of the major advantages associated with using seaweed is that it can grow in ocean water without the need for arabl...
