Abstract

Two-dimensional (2D) materials and their vertical/lateral heterostructures are currently the subject of massive research interests, both for fundamental science and for technological applications in diverse fields, such as electronics, optoelectronics, quantum metrology, spintronics, membranes, energy conversion/storage, and sensing. Integration of 2D materials within real device structures currently represents the main challenge to move from the laboratory stage to industrial applications, especially in the fields of electronics/optoelectronics.This Book is a collection of 9 papers, covering the different key topics of this rapidly developing research field. These include: synthesis of 2D materials, progress in relevant processing issues (contact, doping and mobility engineering), advanced characterization techniques, novel device applications based on the integration of these 2D materials.Many of the papers of this collection are review papers, providing the general introductory information and a broad overview of the most recent advances in the specific topic. Hence, this book can serve both as a general introduction for non-experts in the field and as a guide for scientists/engineers working in the field of 2D materials integration.

Abstract

This work focuses on the analysis and design of multiple element antennas (MEA) and their interaction with the propagation channel. In particular, attention is given to urban channels and how its information throughput, i.e. capacity, can be improved. With this in mind, this work extends an existing network model of the communication system in order to reduce computation time, investigates the communicational limits of MEA systems and proposes a synthesis method for capacity maximization.

Abstract

This work presents investigates the feasibility of the ""directly steered wheels (DSW)"" under operating condition of tramcars. After analyzing the wheel/rail geometric contact between track and DSW, a mathematical model has been developed to describe the lateral dynamics. Based on this model, a robust guidance controller is designed according to the µ-synthesis. The results of simulations show that the DSW with the designed controller can improve the running performance of tramcars significantly.

Abstract

Antimicrobial peptides (AMPs) are gene-encoded, ancient (and important) mediators of innate host defense that exert direct or indirect antimicrobial action as well as possessing other important biologic activities (e.g., neutralization of endotoxin and anti-biofilm action) that help to protect vertebrates, invertebrates and plants from invading pathogens. While the emergence of multi-antibiotic resistant pathogens (and the desperate need to develop new anti-infectives) has been a recent force driving the field, interest in AMPs has an earlier origin in studies of how phagocytes kill bacteria by oxygen-independent processes. AMPs responsible for such killing of microbes by rabbit and human neutrophils were later purified by Ganz, Selsted and Lehrer, which they termed defensins; at the time of this writing, literally thousands of defensin-based publications can be found in the scientific literature! The initial reports on defensins and the earlier report by Boman’s group on the purification and action of an insect AMP represented a historical and defining point for the AMP field as they, in hindsight, demanded the recognition of AMP research as a unique discipline that has important linkages to other important fields of medicine, especially those of microbiology, infectious diseases and immunology. On a personal note, I remember conferences on phagocytes and host defense in the early 1980s where the topic of AMPs was relegated to one short session in a five day period! Now, we have hundreds of international “AMPologists” with expertise in chemistry, biochemistry, molecular and structural biology, cell biology, microbiology, pharmacology, or medicine who have built their research careers around AMPs and can now attend international conferences dedicated to advances in AMP research.

Abstract

Growing plants have a constitutive demand for sulfur to synthesize proteins, sulfolipids and other essential sulfur containing molecules for growth and development. The uptake and subsequent distribution of sulfate is regulated in response to demand and environmental cues. The importance of sulfate for plant growth and vigor and hence crop yield and nutritional quality for human and animal diets has been clearly recognized. The acquisition of sulfur by plants, however, has become an increasingly important concern for the agriculture due to the decreasing S-emissions from industrial sources and the consequent limitation of inputs from atmospheric deposition. Molecular characterization involving transcriptomics, proteomics and metabolomics in Arabidopsis thaliana as well as in major crops revealed that sulfate uptake, distribution and assimilation are finely regulated depending on sulfur status and demand, and that these regulatory networks are integrated with cell cycle, photosynthesis, carbohydrate metabolism, hormonal signaling, uptake and assimilation of other nutrients, etc., to enable plant growth, development, and reproduction even under different biotic and abiotic stresses. This knowledge can be used to underpin approaches to enhance plant growth and nutritional quality of major food crops around the world. Although considerable progress has been made regarding the central role of sulfur metabolism in plant growth, development and stress response, several frontiers need to be explored to reveal the mechanisms of the cross-talk between sulfur metabolism and these processes. In this research topic the knowledge on plant sulfur metabolism is reviewed and updated. Focus is put not only on molecular mechanisms of control of sulfur metabolism but also on its integration with other vital metabolic events. The topic covers 4 major areas of sulfur research: sulfate uptake, assimilation and metabolism, regulation, and role in stress response. We hope that the topic will promote interaction between researchers with different expertise and thus contribute to a more integrative approach to study sulfur metabolism in plants.

Abstract

Psychology straddles areas from the biological to the social and cultural. Within that vast range, there have been recent explosions of interest in neuropsychology, genetics and epigenetics, and the evolutionary bases of mindedness. Correspondingly, there have been conceptual innovations and new empirical evidence in relation to the embodied, social and discursive processes supporting mind and personhood. Simultaneously, awareness of developmental processes and their dynamic interweaving of genetic, physiological, neurological, social and cultural elements has also increased. Might such developments help ‘connect the dots’ between diverse aspects of mindedness and the contexts within which it arises? Whilst it seems clear that mind is co-constituted of both biological and socio-cultural processes, how might we bring these disparate realms of knowledge together? In a number of these areas, suggestive integrative possibilities have been explored (e.g., predictive processing, embodied and situated cognition, dynamic developmental systems theory) and insights such as a focus on action, ‘knowledge as skills’, embeddedness and connectivity have been pursued across a range of disciplines. This edited collection of articles bring together such possibilities – and others - in the same forum in order to provide an opportunity to re-visit a recurring discussion within theoretical psychology: The claimed lack of - and potential for - theoretical synthesis and unity. While the chapters range over a number of areas of research, this collection is focused on current prospects for conceptual synthesis within - or convergence of research between - aspects of mind and mindedness. As is clear from the contributions, it highlights integrative conceptual proposals that emphasize action-orientation, process, embeddedness and connectivity – especially between explanatory ‘levels’. Beyond specific proposals for integration, several of the contributions explicitly or implicitly expose broader questions about the purpose of psychological research, the epistemological and ontological commitments required, and the relevant social, political and economic contexts within which such research is performed. This is perhaps inevitable since any aim for synthesis of various understandings of mind will - or should - lead to consideration of the general implications, beyond the ‘science’, that follow from an integrated account of mind and mindedness. Whether or not the contributions in this volume provide insights into profitable paths towards greater theoretical synthesis in the sciences of mind or, alternatively, provide grist for the mill of renewed skepticism over the potential or even desirability of such synthesis is unpredictable. Whichever the outcome, we feel sure that they will help provoke future productive research in, and thinking about, the sciences of mind.

Abstract

This open access book brings out the state of the art on how informatics-based tools are used and expected to be used in nanomaterials research. There has been great progress in the area in which “big-data” generated by experiments or computations are fully utilized to accelerate discovery of new materials, key factors, and design rules. Data-intensive approaches play indispensable roles in advanced materials characterization. "Materials informatics" is the central paradigm in the new trend. "Nanoinformatics" is its essential subset, which focuses on nanostructures of materials such as surfaces, interfaces, dopants, and point defects, playing a critical role in determining materials properties. There have been significant advances in experimental and computational techniques to characterize individual atoms in nanostructures and to gain quantitative information. The collaboration of researchers in materials science and information science is growing actively and is creating a new trend in materials science and engineering.
