This book reviews a wide-range of genetically modified (GM) crops to understand how they are produced, the impacts on the agricultural industry, and their potential for improving food security. The production of GM crops has now become an invaluable asset in the agricultural toolbox. With a significant portion of the world suffering from hunger and poverty, this book examines how food security can be achieved through GM crops. A wide variety of crops are examined, from the earliest developments of GM tomatoes and potatoes to recent interest in the development of low-cost, high yielding biofuels, such as microalgae. Chapters also discuss the role of GM crops in pest management and the consequential reduction in the use of insecticides. Overall, this book provides an important synthesis of GM crops from their commercial value to the agricultural industry, as well as their potential for improving food security. This book will be of great interest to students and scholars of agricultural engineering, crop science, food biotechology, food security, and those interested in food and agriculture and sustainable development more broadly.

Reconfigurable intelligent surface (RIS) has emerged as a cutting-edge technology for beyond 5G and 6G networks due to its low-cost hardware production, nearly passive nature, easy deployment, communication without new waves, and energy-saving benefits. Unmanned aerial vehicle (UAV)-assisted wireless networks significantly enhance network coverage.Resource allocation and real-time decision-making optimisation play a pivotal role in approaching the optimal performance in UAV- and RIS-aided wireless communications. But the existing contributions typically assume having a static environment and often ignore the stringent flight time constraints in real-life applications. It is crucial to improve the decision-making time for meeting the stringent requirements of UAV-assisted wireless networks. Deep reinforcement learning (DRL), which is a combination of reinforcement learning and neural networks, is used to maximise network performance, reduce power consumption, and improve the processing time for real-time applications. DRL algorithms can help UAVs and RIS work fully autonomously, reduce energy consumption and operate optimally in an unexpected environment.This co-authored book explores the many challenges arising from real-time and autonomous decision-making for 6G. The goal is to provide readers with comprehensive insights into the models and techniques of deep reinforcement learning and its applications in 6G networks and internet-of-things with the support of UAVs and RIS.Deep Reinforcement Learning for Reconfigurable Intelligent Surfaces and UAV Empowered Smart 6G Communications is aimed at a wide audience of researchers, practitioners, scientists, professors and advanced students in engineering, computer science, information technology, and communication engineering, and networking and ubiquitous computing professionals.

6G networks are expected to provide one-microsecond latency communication with a billion devices competing for resources 1000 times faster than current standards. Increases in network speed, heterogeneity, virtualization, better radio requirements and adaptive communications will place new demands on physical layer security. Moreover, IoT, blockchain, and artificial intelligence are enabling technologies that require rapid data rates, raising a significant burden on the network's physical layer, requiring that security must be attained at a fast pace, and that the network must be resilient to accommodate sudden changes to the configurations or the load.Physical layer (PHY) security solutions are needed that have the capacity to handle the new demands of 6G networks, whilst protecting those networks against risk factors such as interference, data spoofing, replay attacks, side-channel attacks, jamming, traffic analysis, and cyber-vandalism attacks. This comprehensive book addresses the PHY security challenges and proposes efficient and resilient physical layer security solutions for beyond 5G networks leading to 6G. Several topics have emerged that rely on PHY security in solving real-world network challenges such as ultra-dense networks, adaptive communication, distributed technology, and artificial intelligence.Physical Layer Security for 6G Networks helps readers understand the expectations of 6G's physical layer security in supporting pervasive and integrated communication networks, AI convergence and utility, and develop better sensing solutions, which go beyond cognitive radio, device-to-device or mm-wave communications.

Digital twin (DT) technology is a real-time evolving digital duplicate of a physical object or process that contains all its history. It is enabled by massive real-time multi-source data collection and analysis. While 6G is considered as an enabler of digital twins, DT can also be a facilitator for integrating AI and 6G towards reliable, pervasive and efficient intelligent technologies.While the DT concept is familiar among aerospace and industrial engineers, it is a relatively new topic among electronic, electrical, computer, communications and networking engineers. For future massive-scale industrial internet-of-things (IoT) applications facilitated by DTs, a 6G network will be much more advantageous than its 5G counterpart.Digital Twins for 6G: Fundamental theory, technology and applications aims to bring together knowledge from industrial practitioners and researchers, and to introduce novel concepts that can help address the challenges associated with this interdisciplinary topic. The authors will cover fundamentals, enabling technologies, standards and advanced topics of DT and 6G to demystify the DT concept and its networking requirements and benefits, support a broader understanding of DT and its relationship with 6G to a larger audience, support learning and understanding for researchers and professionals working on 5G and 6G, and create a foundation on DT and 6G for the international research community.This book is intended to be both a tutorial of the important topics around digital twin and advanced wireless communications technologies, including 6G, as well as an advanced overview for technical professionals in the communications industry, technical managers, and researchers in both academia and industry.
