Air plant (Tillandsia spp.) is a kind of special plants that can grow in the air and does not need soil. It is originated from Central and South America and has been introduced and cultivated all over the world because of its unique ornamental value. As a special epiphytic group, the root function of air plant is degraded, and it's growth completely depends on the leaves to absorb water and nutrients from the air, so its leaf absorption capacity is strong.The book contains a systematic study on the biomonitoring, purification and dynamic response of air plant to air pollutants. The results show that air plant is a broad spectrum plant to absorb atmospheric pollutants, including heavy metals (Hg, Cd, Pb etc.), formaldehyde, radon (Rn) and particulate matters (PM10, PM2.5 etc.). The specialized foliar trichomes densely covering Tillandsia leaves played a major role in the absorption of various pollutants. Moreover, air plant has a strong ability to resist air pollution damage, and has various unique avoidance or mitigation mechanisms in structure, physiology, gene and other aspects. Hormesis effect, in the framework of which a toxicant has a stimulating effect at low doses and a toxic effect at high doses, can commonly occur in this plant. Plant resistance genes and glutathione (GSH) may play an important role in the generation of hormesis.

Flexible Distribution Networks facilitates the enhanced flexibility, efficiency and reliability of distribution networks under complex operating environments delivered by high DG penetration. Considering the high share of DG and flexibility improvement brought by SOP-type power electronic devices, the work aims to solve the issues of optimal operation of flexible distribution networks. Technical solutions for flexible operation problems of FDN are discussed in depth, including efficient analytical methods with high penetration of DG, SOP-based optimal operation methods with uncertainty, and high-performance convex optimization algorithms. Readers will develop sound knowledge and gain insights into the optimal operation of FDN with high penetration of DG.

This book represents an introduction to ecoacoustics theory, to the application of the Acoustic Complexity Indices (ACIs) to acoustic survey, and to the use of an innovative software to process acoustic data. It enables readers to comprehend the main principles that guide the recent development of ecoacoustics and offers a synthesis about the role of sound in the ecological research.Readers will be introduced to the use of the ACIs by a detailed description of the main algorithms recently formulated and on their correct application in the acoustic processing concurring to the creation of sonic information systems. Readers will also find a new dedicated software application, namely SonoScape, that is described in detail with its codes attached in the supplementary material in a completely visible format. The SonoScape is a performing software application operating in MatLab® and is enriched of several options to manage single and large collection of acoustics files. It vides the feasibility to process data at different temporal scale, using different combination of parameters, and to extract novel complexity measures such as entropy and fractal dimension of ecoacoustic events. It also offers functions to visualize the results using customized 3-D plots or ternary plots, intuitively demonstrating the patterns of ACIs based on the vast number of numerical results.Finally, this book provides several examples of case studies with the aim of better understanding the potentiality of ACIs and the power of SonoScape as multitasking software to approaching the complexity of the ecoacoustic investigation.Students and scholars in ecology, land managers and technicians may find an important tool to interpret the complex relationship between humans and natural processes when sounds are adopted as proxy.

Based on the design theory and development experience of Beidou navigation satellite system (BDS), this book highlights the space segment and the related satellite technologies as well as satellite-ground integration design from the perspective of engineering. The satellite navigation technology in this book is divided into uplink and reception technology, broadcasting link technology, inter-satellite link technology, time-frequency system technology, navigation signal generation and assessment technology, navigation information management technology, autonomous operation technology of navigation satellite. In closing, the book introduces readers to the technological development status and trend of BDS and other GNSS, and propose the technologies of future development.Unlike most current books on this topic, which largely concentrate on principles, receiver design or applications, the book also features substantial information on the role of satellite system in the GNSS and the process of signal information flow, and each chapter not only studies on the theoretical function and main technologies, but also focuses on engineering development. Accordingly, readers will gain not only a better understanding of navigation satellite systems as a whole, but also of their main components and key technologies.

This brief examines current research on cooperative device-to-device (D2D) communication as an enhanced offloading technology to improve the performance of cognitive radio cellular networks. By providing an extensive review of recent advances in D2D communication, the authors demonstrate that the quality of D2D links significantly affects offloading performance in cellular networks, which motivates the design of cooperative D2D communication. After presenting the architecture of cooperative D2D communication, the challenges of capacity maximization and energy efficiency are addressed by optimizing relay assignment, power control and resource allocation. Furthermore, cooperative D2D communication is enhanced by network coding technology, and then is extended for broadcast sessions. Along with detailed problem formulation and hardness analysis, fast algorithms are developed by exploiting problem-specific characteristics such that they can be applied in practice.

This book describes the physiological effects of acupuncture, which can be used to enhance traditional Chinese practice. Following a history of the development of traditional Chinese medicine, the first section covers the scientific basis and mechanism of acupuncture, particularily in relation to the cardiovascular system. The second section is devoted to clinical case studies, illustrating that scientific knowledge can be integrated with traditional concepts in Chinese medicine to provide effective treatments. This is an informative and provocative text that describes the current status of knowledge and challenges scientists to better define acupuncture therapy. It is a useful reference guide for advanced students and practitioners of traditional Chinese medicine and acupuncture, as well as scientists conducting physiological and pharmacological research on acupuncture.
