    The electricity systems of many countries are currently undergoing a process of transformation. Market liberalization has induced major mergers and acquisitions in the electricity sector, but has also forced companies to seek out new business areas. Environmental regulations, like the Kyoto process and the European Emissions Trading Scheme, are exposing the sector to external pressure. New technologies - such as renewable energy, combined heat and power (CHP), or "clean coal" technologies - are emerging. Recent worldwide experiences with blackouts have once more put security of supply on the agenda. In Germany, the nuclear phase-out and decommissioning of outdated coal plants will lead to a need for replacement of more than one third of the current generation capacity by 2020. The need for replacement is an extremely important driving force for the current transformation, forcing conventional and new technologies to compete for a role in the future energy supply. The overall transformation of electricity systems is neither driven nor shaped by technical or societal modifications alone, but rather by a rich diversity of processes in the realms of technology, politics, society and economy.

  • Cette étude est consacrée à l'examen de la théorie du monde social qui se découvre dans la phénoménologie d'Edmund Husserl : est-elle à même de dire les phénomènes sociaux, sur quel mode et avec quels résultats ?Dans un premier moment, nous reconstituons le propos des deux « ontologies sociales » qui pensent le monde social en son essence et en ses essences : d'une part, l'ontologie de la région « monde social », subordonnée à la région de l'« esprit » et élaborée à partir d'une phénoménologie de la communication ; d'autre part, l'ontologie morphologique et eidétique des formes essentielles de communautés sociales. Dans un second moment, nous suivons l'élaboration d'une « sociologie transcendantale » qui reconsidère le rapport de la subjectivité transcendantale au monde social. Nous montrons comment les développements de la théorie de la personne dans la perspective de la phénoménologie génétique, qui semblent nous détourner de la considération de sa socialité, précisent en réalité le rapport du sujet personnel au monde social sous l'angle de sa « mienneté », de l'habitualité et de la familiarité d'une part, et dans la perspective d'une éthique sociale d'autre part. On établit enfin comment, autour de la Krisis, la théorie du monde de la vie fournit le cadre théorique d'une « sociologie transcendantale » qui se développe, sur le fond d'une anthropologie du monde commun, comme théorie de la générativité. De l'ontologie sociale à la sociologie transcendantale, cette recherche est conçue comme une investigation des ressources et des difficultés de la voie par l'ontologie d'accès à la réduction transcendantale, relativement à la question du « social ».Remarquable enquête menée sur l'expérience sociale du sujet, la phénoménologie husserlienne du monde social est susceptible d'intéresser le sociologue comme le philosophe qui s'interroge sur la nature du « social » en général.

  • Relative entropy has played a significant role in various fields of mathematics and physics as the quantum version of the Kullback-Leibler divergence in classical theory. Many variations of relative entropy have been introduced so far with applications to quantum information and related subjects. Typical examples are three different classes, called the standard, the maximal, and the measured f-divergences, all of which are defined in terms of (operator) convex functions f on (0,8) and have respective mathematical and information theoretical backgrounds. The a-Rényi relative entropy and its new version called the sandwiched a-Rényi relative entropy have also been useful in recent developments of quantum information.
    In the first half of this monograph, the different types of quantum f-divergences and the Rényi-type divergences mentioned above in the general von Neumann algebra setting are presented for study. While quantum information has been developing mostly in the finite-dimensional setting, it is widely believed that von Neumann algebras provide the most suitable framework in studying quantum information and related subjects. Thus, the advance of quantum divergences in von Neumann algebras will be beneficial for further development of quantum information. 
    Quantum divergences are functions of two states (or more generally, two positive linear functionals) on a quantum system and measure the difference between the two states. They are often utilized to address such problems as state discrimination, error correction, and reversibility of quantum operations. In the second half of the monograph, the reversibility/sufficiency theory for quantum operations (quantum channels) between von Neumann algebras via quantum f-divergences is explained, thus extending and strengthening Petz' previous work.
    For the convenience of the reader, an appendix including concise accounts of von Neumann algebras is provided.

  • The package of Gromov's pseudo-holomorphic curves is a major tool in global symplectic geometry and its applications, including mirror symmetry and Hamiltonian dynamics. The Kuranishi structure was introduced by two of the authors of the present volume in the mid-1990s to apply this machinery on general symplectic manifolds without assuming any specific restrictions. It was further amplified by this book's authors in their monograph Lagrangian Intersection Floer Theory and in many other publications of theirs and others. Answering popular demand, the authors now present the current book, in which they provide a detailed, self-contained explanation of the theory of Kuranishi structures.
    Part I discusses the theory on a single space equipped with Kuranishi structure, called a K-space, and its relevant basic package. First, the definition of a K-space and maps to the standard manifold are provided. Definitions are given for fiber products, differential forms, partitions of unity, and the notion of CF-perturbations on the K-space. Then, using CF-perturbations, the authors define the integration on K-space and the push-forward of differential forms, and generalize Stokes' formula and Fubini's theorem in this framework. Also, "virtual fundamental class" is defined, and its cobordism invariance is proved.
    Part II discusses the (compatible) system of K-spaces and the process of going from "geometry" to "homological algebra". Thorough explanations of the extension of given perturbations on the boundary to the interior are presented. Also explained is the process of taking the "homotopy limit" needed to handle a system of infinitely many moduli spaces. Having in mind the future application of these chain level constructions beyond those already known, an axiomatic approach is taken by listing the properties of the system of the relevant moduli spaces and then a self-contained account of the construction of the associated algebraic structures is given. This axiomatic approach makes the exposition contained here independent of previously published construction of relevant structures. 

  • This monograph focuses on the mathematical and numerical analysis of simplicial partitions and the finite element method. This active area of research has become an essential part of physics and engineering, for example in the study of problems involving heat conduction, linear elasticity, semiconductors, Maxwell's equations, Einstein's equations and magnetic and gravitational fields.
    These problems require the simulation of various phenomena and physical fields over complicated structures in three (and higher) dimensions. Since not all structures can be decomposed into simpler objects like d-dimensional rectangular blocks, simplicial partitions are important. In this book an emphasis is placed on angle conditions guaranteeing the convergence of the finite element method for elliptic PDEs with given boundary conditions. 
    It is aimed at a general mathematical audience who is assumed to be familiar with only a few basic results from linear algebra, geometry, and mathematical and numerical analysis. 

  • This book offers a wide-ranging and up-to-date overview of the basic science underlying PET and
    its preclinical and clinical applications in modern medicine. In addition, it provides the reader with a sound understanding of the scientific principles and use of PET in routine practice and biomedical imaging research. The opening sections address the fundamental physics, radiation safety, CT scanning dosimetry, and dosimetry of PET radiotracers, chemistry and regulation of PET radiopharmaceuticals, with information on labeling strategies, tracer quality control, and regulation of radiopharmaceutical production in Europe and the United States. PET physics and instrumentation are then discussed, covering the basic principles of PET and PET scanning systems, hybrid PET/CT and PET/MR imaging, system calibration, acceptance testing, and quality control. Subsequent sections focus on image reconstruction, processing, and quantitation in PET and hybrid PET and on imaging artifacts and correction techniques, with particular attention to partial volume correction and motion artifacts. The book closes by examining clinical applications of PET and hybrid PET and their physiological and/or molecular basis in conjunction with technical foundations in the disciplines of oncology, cardiology and neurology, PET in pediatric malignancy and its role in radiotherapy treatment planning. Basic Science of PET Imaging will meet the needs of nuclear medicine practitioners, other radiology specialists, and trainees in these fields.

Common underlying principles and connections between different perspectives are developed; results are illustrated through graphs and explained heuristically. This book can be used as a reference and is aimed toward graduate students, researchers and practitioners in mathematics, finance, economics, and optimization. Topics include: Markowitz portfolio theory, growth portfolio theory, fundamental theorem of asset pricing emphasizing the duality between utility optimization and pricing by martingale measures, risk measures and its dual representation, hedging and super-hedging and its relationship with linear programming duality and the duality relationship in dynamic hedging of contingent claims

  • This book expands on the classical statistical multivariate analysis theory by focusing on bilinear regression models, a class of models comprising the classical growth curve model and its extensions. In order to analyze the bilinear regression models in an interpretable way, concepts from linear models are extended and applied to tensor spaces. Further, the book considers decompositions of tensor products into natural subspaces, and addresses maximum likelihood estimation, residual analysis, influential observation analysis and testing hypotheses, where properties of estimators such as moments, asymptotic distributions or approximations of distributions are also studied. Throughout the text, examples and several analyzed data sets illustrate the different approaches, and fresh insights into classical multivariate analysis are provided. This monograph is of interest to researchers and Ph.D. students in mathematical statistics, signal processing and other fields where statistical multivariate analysis is utilized. It can also be used as a text for second graduate-level courses on multivariate analysis.

  • This timely book allows clinicians of the nervous system, who are increasingly confronted with degenerative and psychiatric diseases, to familiarize themselves with the cerebral amygdala and the anatomical structures involved in these pathologies.

  • Bimetallic nanoparticles, also called nanoalloys, are at the heart of nanoscience because of their ability to tune together composition and size for specific purposes. By approaching both their physical and chemical properties, Nanoalloys: Synthesis, Structure & Properties provides a comprehensive reference to this research field in nanoscience by addressing the subject from both experimental and theoretical points of view, providing chapters across three main topics:
    Growth and structural properties
    Thermodynamics and electronic structure of nanoalloys
    Magnetic, optic and catalytic propertiesThe growth and elaboration processes which are the necessary and crucial part of any experimental approach are detailed in the first chapter. Three chapters are focused on the widely used characterization techniques sensitive to both the structural arrangements and chemistry of nanoalloys. The electronic structure of nanoalloys is described as a guide of useful concepts and theoretical tools.  Chapters covering thermodynamics begin with bulk alloys, going to nanoalloys via surfaces in order to describe chemical order/disorder, segregation and phase transitions in reduced dimension. Finally, the optical, magnetic and catalytic properties are discussed by focusing on nanoparticles formed with one element to track the modifications which occur when forming nanoalloys. The range and detail of Nanoalloys: Synthesis, Structure & Properties makes it an ideal resource for postgraduates and researchers working in the field of nanoscience looking to expand and support their knowledge of nanoalloys.

  • Forewords by Claes-Göran Granqvist, Uppsala University, Sweden, and Neal F. Lane, Rice University, TexasNanomaterials inevitably have bright prospects, but even now they play an important role in many areas of industry. Some of these new materials are commercially available and are used in off the shelf products, others are important model systems for physicochemical and materials science research. However, research findings and application data are not compiled in a single work. The Springer Handbook of Nanomaterials collects description and data of materials which have dimensions on the nanoscale. The description of nanomaterials follows the interplay of structure, properties, processing and applications mainly in their solid phase. The chapters were arranged according to the classical materials-science classifications: carbon materials, metals, ceramics, composites, and biomaterials. For each part, materials structures represent different dimensionality; zero-dimensional clusters, nanoparticles and quantum dots, one-dimensional nanowires and nanotubes, and two-dimensional thin films and surfaces. Combinations cover for instance nanostructured and hybrid materials. Almost 100 leading scientists from academia and the industry were selected to write the 32 chapters and collect the physical, chemical and mechanical data. The handbook was written and compiled for professionals and practitioners, materials scientists, physicists and chemists at universities, as well as in the fields of industrial research and production.The Handbook is organized in seven parts. Part A: NanoCarbons. Part B: NanoMetals. Part C: NanoCeramics. Part D: NanoComposits. Part E: Nanoporous Materials. Part F: Organic and Biomaterilas. Part G: Applications and Impact.  

  • The ever increasing emission of carbon dioxide due to rapid industrialization, urbanization, unplanned tourism and alteration of land use pattern is causing unprecedented changes to marine biodiversity. Irrespective of political philosophy, nation, caste, sex and religion, mankind is under the appalling shadow of climate change. Today nature-based approaches for the mitigation of climate change are increasingly accepted as part of the low-cost solution. Thrust has been given by several scientific communities to assess the magnitude and viability of carbon sequestering potential of plants. Coastal producer communities like mangroves, salt marsh grass, seagrass beds, and seaweeds absorb atmospheric carbon dioxide during the process of photosynthesis. This carbon known as the `blue carbon' is thus associated with the marine and estuarine ecosystems. However, a number of gaps in our scientific knowledge on blue carbon domain still exist. Molluscs, coral reefs, phytoplankton, which are amongst the important storehouses of carbon, have not been addressed. Very few scientific studies on the carbon stored in these valuable natural vaults have been performed, and no data bank is available on their carbon sequestering capacity on global basis. The methodologies for assessing blue carbon stock also need further standardization so that credit from blue carbon reservoir is accepted by the International bodies in the form of a concrete policy. It is a matter of great appreciation that Conservation International (CI), the International Union for Conservation of Natural Resources (IUCN), and the Intergovernmental Oceanic Commission (IOC) of UNESCO is collaborating with governments, research institutions, non-governmental and international organizations, and communities around the world to develop management approaches, financial incentives and policy mechanisms for ensuring conservation and restoration of blue carbon ecosystems and implement projects around the world that demonstrate the feasibility of blue carbon accounting, management, and incentive agreements. The present book has critically presented the data bank for each community of blue carbon not merely in the form of text description, but also through case studies that are the outcomes of research projects and pilot programmes.

  • This eagerly awaited book offers a unique, comprehensive scientific study of the anatomy of the organ of female sexual pleasure. The authors use macroscopic and microscopic research to guide the reader from the glans, the visible part of the clitoris, where they explore the impressive sensory corpuscles, to the hidden roots of the bulbo-clitoral organ. They show its complexity, its exact location within the external genitalia and its intimate relationship with the urethro-vaginal pyramid.They also remind us that throughout history there has been a failure to understand this organ and explain that this misunderstanding remains the cause of persistent excisions, criminal mutilating practices that have not yet been eradicated.Using extensive iconography, they demonstrate throughout this book that the bulbo-clitoral organ is an exceptional natural treasure that every woman possesses and that every man should know well.

  • The Enhancing Diversity in Graduate Education (EDGE) Program began twenty years ago to provide support for women entering doctoral programs in the mathematical sciences. With a steadfast commitment to diversity among participants, faculty, and staff, EDGE initially alternated between Bryn Mawr and Spelman Colleges. In later years, EDGE has been hosted on campuses around the nation and expanded to offer support for women throughout their graduate school and professional careers. The refereed papers in A Celebration of the EDGE Program's Impact on the Mathematics Community and Beyond range from short memoirs, to pedagogical studies, to current mathematics research. All papers are written by former EDGE participants, mentors, instructors, directors, and others connected to EDGE. Together, these papers offer compelling testimony that EDGE has produced a diverse new generation of leaders in the mathematics community. This volume contains technical and non-technical works, and it is intended for a far-reaching audience, including mathematicians, mathematics teachers, diversity officers, university administrators, government employees writing educational or science policy, and mathematics students at the high school, college, and graduate levels. By highlighting the scope of the work done by those supported by EDGE, the volume offers strong evidence of the American Mathematical Society's recognition that EDGE is "a program that makes a difference."
    This volume offers unique testimony that a 20-year old summer program has expanded its reach beyond the summer experience to produce a diverse new generation of women leaders, nearly half of whom are underrepresented women. While some books with a women-in-math theme focus only on one topic such as research or work-life balance, this book's broad scope includes papers on mathematics research, teaching, outreach, and career paths.

  • EtYIL 2019 comes out while the world is in the midst of a new coronavirus pandemic that has infected millions and killed thousands of people without distinction as to age, race, colour, or creed. As an attack on all humanity, Covid-19, the disease caused by the coronavirus, has challenged the fitness of the global order as never before, and its institutional and normative frameworks have been found wanting. As is often the case in such circumstances, when the WHO is denied resources to assist those countries or the WTO is unable to guarantee access to Covid-19 medical supplies and protective equipment, it is the poorest nations that suffer the most. EtYIL's mission is to provide a platform for purpose-oriented scholarly analysis and debate on issues of particular significance for African countries such as Covid-19, disputes over Nile water resources, and Ethiopia-Eritrea relations. Although the pandemic came too late for this issue of EtYIL, we have managed to include two important articles that examine the subject from geostrategic and legal perspectives. EtYIL 2019 also addresses a number of other topical issues, including the responsibility of the UN Security Council (UNSC) in climate-related risks to least developed countries, the Global South's approach to environmental protection, the challenges of international regulation of arms brokering, and the contributions of Martin Luther King, Jr. to Pan-Africanism and international human rights law. Finally, the Yearbook also continues its coverage of regional issues such as the evolving Ethiopia-Eritrea relations, Djibouti's accession to the ICSID Convention; the trilateral negotiations between Ethiopia, Sudan and Egypt over the Grand Ethiopian Renaissance Dam and the U.S. meddling and the role of the UNSC on the issue have also been covered. As before, our contributors come from all over the world, to all of whom we extend our sincere appreciations.

  • Attention deficit disorder, attention deficit hyperactive disorder, pervasive developmental disorder, obsessive-compulsive disorder, asperger's syndrome, and autism, to name but a few, may be viewed as points on a spectrum of developmental disabilities in which those points share features in common and possibly etiology as well, varying only in severity and in the primary anatomical region of dysfunctional activity.
    This text focuses on alterations of the normal development of the child. A working theory is presented based on what we know of the neurological and cognitive development in the context of evolution of the human species and its brain. In outlining our theory of developmental disabilities in evolutionary terms, the authors offer evidence to support the following notions: Bipedalism was the major reason for human neocortical evolution; Cognition evolved secondary and parallel to evolution of motricity; There exists an overlap of cognitive and motor symptoms; Lack of thalamo-cortical stimulation, not overstimulation, is a fundamental problem of developmental disabilities; A primary problem is dysfunctions of hemisphericity; Most conditions in this spectrum of disorders are the result of a right hemisphericity; Environment is a fundamental problem; All of these conditions are variations of the same problem; These problems are correctable; Hemisphere specific treatment is the key to success.

  • This book focuses on the development of stapled peptides, a novel molecular modality used to regulate aberrant intracellular protein-protein interactions (PPIs). The author designs and presents a novel helical peptide stabilization methodology by constructing a chiral cross-linker moiety, namely "chiral center induced peptide helicity (CIH)". The book demonstrates that a precisely positioned carbon chiral center on tether can decisively determine the secondary structure of a peptide, and that the R-configured peptide is helical, while the S-configured peptide is non-helical. Further, it reports that helicity-enhanced R isomer peptides displayed significantly enhanced cell permeability and target binding affinity, as well as tumor inhibition efficiency, in comparison to S isomer peptides. The book will not only advance readers' understanding of the basic principle of stapled peptides, but also accelerate the clinical transformation of stapled peptide drugs.
