This study focused on one-pot green synthesis of zinc oxide nanoparticles (ZnO NPs) using Ipomoea Sagittifolia Burm.f plant extract. Various techniques were used for particle characteristics such as crystallinity, morphology, elemental composition, particle size, and particle distribution. These techniques reveal the ZnO NPs formation, phytochemicals presence, crystalline nature, and hexagonal wurtzite structure with a size of 37-51 f 8.5 nm. The antibacterial activity of plant extract and ZnO NPs were performed against Staphylococcus aureus, Streptococcus pyogenes, Klebsiella pneumoniae, and Escherichia coli pathogenies. Among four, S. aureus showed the highest zone of inhibition than others. The antioxidant efficiency of plant extract and ZnO NPs were examined. The anticancer activity against A549 and MCF7 cell lines were analysed, MCF7 showed the highest activity (IC50 = 64.41 % and 47.02 %) than A549 (86.09 % and 65.47 %) at 100 mu g/mL. The results were validated with Amoxicillin, doxorubicin and Vero cell lines. Furthermore, molecular docking was performed to study the interactions between the active sites of the target proteins with ligands were reported. The antibacterial strain S. aureus showed the highest mean binding energy -2.92 kcal/mol, -4.10 kcal/mol and -5.03 kcal/mol for the plant extract, ZnO NPs, and Amoxicillin, respectively. Likewise, the anticancer activity against A549, and MCF7 cell lines were analyzed, MCF7 showed the highest activity with mean binding energy of -4.18 kcal/mol, -4.39 kcal/mol and -4.68 kcal/mol for bioactive molecule, ZnO NPs and doxorubicin, respectively. In addition, the degradation efficiency of NPs with methylene blue was 97.8 % after 90 min of exposure time under direct sunlight.

Ship wake identification is crucial for analyzing ocean surface synthetic aperture radar (SAr) pictures because ship wakes typically include important vessel information. A significant proportion of detection algorithms make use of the linear traits of ship wakes by converting the lines in the spatial domain into either dark or light points in a transform domain, using techniques like the Hough or radon transforms. This study presents a novel approach for detecting ship wakes using a Gaussian Mixture Model (GMM). The method involves obtaining the radon transform of the SAr image, which enhances the visibility of linear features. In comparison to the state of art methodologies, the findings show that the method is successful in achieving greater wake detection accuracies. © 2024 IEEE.

Quantum computing poses a significant threat to traditional cryptographic systems, necessitating the exploration of robust alternatives to secure data transmission in the cloud. This abstract delves into the integration of Post-Quantum Cryptography (PQC) and Cloud Security Posture Management (CSPM) as a comprehensive solution. The proposed framework advocates for the adoption of a variant of the McEliece cryptosystem within the cloud infrastructure, providing resistance against potential quantum attacks. Encryption, fortified by Post-Quantum Cryptography, emerges as the dominant method for ensuring the security of cloud-stored data. In parallel, Cloud Security Posture Management (CSPM) is introduced as a set of security protocols designed to identify and remediate cloud misconfigurations, enhancing the overall security posture. This research highlights the synergy between PQC and CSPM, showcasing their collective effectiveness in mitigating emerging threats in cloud computing. The integration of Quantum Key distribution (QKd) further enhances data security, ensuring the confidentiality and integrity of transmitted information. The proposed model not only addresses current data breach challenges but also anticipates the evolving landscape of quantum computing, providing a forward-looking solution for secure data transmission in cloud environments. © 2024 IEEE.

In this new era of wireless communication technology, the design and analysis of microstrip patch antennas for X-band applications, which connects billions of people and machines for radar and satellite applications, is a pervasive practice. The proposed antenna measures 24mm by 18mm and consists of a 1.57mm thick Fr4 substrate. The substrate's dielectric constant is 0.0009, and its relative permittivity is 2.2. A 50-microstrip line delivers the excitation. The evaluation and simulation of the antenna's performance took place using AdS 2020. The X-band applications operate over a frequency range of about 8 to 11 GHz, where the return loss is -10 dB. Its emission pattern is consistent, ranging from 5.28 dBi, providing an average gain that is more prominent and highly suitable for X-band satellite applications. © 2024 IEEE.

Ensuring the safety and efficiency of manufacturing processes is required in Industry 4.0. To address this, an intelligent Poka Yoke system is proposed, specifically designed for monitoring and controlling Industry Programmable Logic Controller machines. This system prioritizes security by requiring strict staff authorization, providing timely alerts, and granting access privileges based on predetermined criteria. It efficiently prevents unauthorized access and minimizes potential industrial dangers by leveraging modern technology such as employee access keys and NFC authentication. NFC is used to authenticate employee credentials, allowing access to only approved jobs by using raspberry Pi Pico as a controller. The technology detects anomalies and safety threats in real time while continuously monitoring equipment operations. The generated data is virtualized in a user-friendly web application, conveniently stored in Mongo dB cloud, allowing for instant notifications and automated equipment shutdown when necessary. This system improves workplace security, safety, and efficiency by streamlining operations and increasing productivity. © 2024 IEEE.

The pandemic situation created by COVId’19 is ridiculous. It has made even the blood relations hide themselves from the infected person. The whole world was stunned by this situation. This is because of the uncertainty in the way in which this disease is spread. As an advancement of this disease, a few other variants like delta, omicron etc. also got spread. It is essential to find a solution to this situation. The variants Omicron and delta are taken into consideration here. Though both the vibrant colours look alike, the symptoms and prevention methods changes for each of these vibrants. This work aims to make a study of the parameters responsible for these variants. As a result of this study, the parameters involved in the spread of these diseases are identified, and the prevention parameters are concluded. The major benefit of this comparatively study is to identify the parameters that are inconclusive, applying the concepts of fuzzy cognitive maps and neutrosophic cognitive maps is applied to bring out the result © 2023, Neutrosophic Sets and *** rights reserved.

In India, where agriculture sustains over 70% of the population, the impact of millet diseases on crop yield and economic outcomes for farmers cannot be overstated. With the advent of digitalization permeating various sectors, including agriculture, leveraging technology becomes imperative for enhancing productivity and ensuring food security. The ability to detect and manage Millet’s diseases efficiently is crucial for maximizing crop yield and minimizing losses. deep learning, mostly Convolutional Neural Networks (CNNs), has appeared as well as an influential tool in digital image processing, offering significant advantages over traditional methods. Leveraging CNNs for the recognition and categorization of Millet's diseases presents a promising solution to this longstanding challenge. The process of Millet's disease detection using CNN involves several key steps, together with acquiring images, initialization, partition, division, as well as disease identification. In conclusion, the integration of CNN-based Millet’s disease detection systems holds immense potential for revolutionizing agricultural practices in India. By connecting the supremacy of deep learning and digitalization, stakeholders can work towards confirming food security, increasing farm profitability, and promoting supportable agricultural practices. In this article, we obtained a 97.8% accuracy in detecting Plant diseases using a CNN-based approach. © 2025 IEEE.
