COVID-19. For months, the coronavirus has been holding the world in a death grip. By now, it's dawning on people that nothing will ever be the same. It's the liberal societies of the West that are feeling the merciless impact the most. Besides the immense, spiraling costs, they must also cope with the reality that their freedom-orientated societal models are beginning to unravel because of this disaster. Because of the COVID-19 pandemic, the West is faltering. The West as a colossus with feet of clay- that’s what’s impelling the men around Chinese intelligence agent Yue Fei. Author Klaus Mewes has written a gripping thriller, a sophisticated mixture weaving together geostrategy, the history of the virus pandemic, and the research behind it. Klaus also expertly uses China’s breathtaking development and eventful history over the past thirty years to infuse his story with realism. The author sheds light on the - fictitious, to be sure - events leading up to the outbreak of the pandemic. Meanwhile, a young woman physician, Shenmi, lives through the 1989 events that occurred on Tiananmen Square. Traumatized, she withdraws emotionally. That is, until the death of a boy during the 1997 H5N1 flu epidemic changes her life yet again, and she resolves to dedicate herself to researching viruses - specifically, coronaviruses. Yue Fei, however, the cunning intelligence agent, is playing his own game. Failing in his hunt for dissidents and professionally exiled as a consequence, he contemplates revenge and the opportunity to rehabilitate himself in the eyes of his superiors. One day, by random chance, he stumbles across an old acquaintance - whereupon he hatches a plan that will change the world. Now begins a breathless race against time.
This book presents an up-to-date formalism of non-equilibrium Green's functions covering different applications ranging from solid state physics, plasma physics, cold atoms in optical lattices up to relativistic transport and heavy ion collisions. Within the Green's function formalism, the basic sets of equations for these diverse systems are similar, and approximations developed in one field can be adapted to another field. The central object is the self-energy which includes all non-trivial aspects of the system dynamics. The focus is therefore on microscopic processes starting from elementary principles for classical gases and the complementary picture of a single quantum particle in a random potential. This provides an intuitive picture of the interaction of a particle with the medium formed by other particles, on which the Green's function is built on.
Adopting a unique approach, this novel textbook integrates science and business for an inside view on the biotech industry. Peering behind the scenes, it provides a thorough analysis of the foundations of the present day industry for students and professionals alike: its history, its tools and processes, its markets and products. The authors, themselves close witnesses of the emergence of modern biotechnology from its very beginnings in the 1980s, clearly separate facts from fiction, looking behind the exaggerated claims made by start-up companies trying to attract investors. Essential reading for every student and junior researcher looking for a career in the biotech sector.
This book presents a comprehensive overview of medical image analysis. Practical in approach, the text is uniquely structured by potential applications. Features: presents learning objectives, exercises and concluding remarks in each chapter, in addition to a glossary of abbreviations; describes a range of common imaging techniques, reconstruction techniques and image artefacts; discusses the archival and transfer of images, including the HL7 and DICOM standards; presents a selection of techniques for the enhancement of contrast and edges, for noise reduction and for edge-preserving smoothing; examines various feature detection and segmentation techniques, together with methods for computing a registration or normalisation transformation; explores object detection, as well as classification based on segment attributes such as shape and appearance; reviews the validation of an analysis method; includes appendices on Markov random field optimization, variational calculus and principal component analysis.
The literature on the spectral analysis of second order elliptic differential operators contains a great deal of information on the spectral functions for explicitly known spectra. The same is not true, however, for situations where the spectra are not explicitly known. Over the last several years, the author and his colleagues have developed new,
Real life phenomena in engineering, natural, or medical sciences are often described by a mathematical model with the goal to analyze numerically the behaviour of the system. Advantages of mathematical models are their cheap availability, the possibility of studying extreme situations that cannot be handled by experiments, or of simulating real systems during the design phase before constructing a first prototype. Moreover, they serve to verify decisions, to avoid expensive and time consuming experimental tests, to analyze, understand, and explain the behaviour of systems, or to optimize design and production. As soon as a mathematical model contains differential dependencies from an additional parameter, typically the time, we call it a dynamical model. There are two key questions always arising in a practical environment: 1 Is the mathematical model correct? 2 How can I quantify model parameters that cannot be measured directly? In principle, both questions are easily answered as soon as some experimental data are available. The idea is to compare measured data with predicted model function values and to minimize the differences over the whole parameter space. We have to reject a model if we are unable to find a reasonably accurate fit. To summarize, parameter estimation or data fitting, respectively, is extremely important in all practical situations, where a mathematical model and corresponding experimental data are available to describe the behaviour of a dynamical system.
This much-needed book presents a clear and very practice-oriented overview of thermal separation processes. An extensive introduction elucidates the physical and physicochemical fundamentals of different unit operations used to separate homogenous mixtures. This is followed by a concise text with numerous explanatory figures and tables referring to process and design, flowsheets, basic engineering and examples of separation process applications. Very helpful guidance in the form of process descriptions, calculation models and operation data is presented in an easy-to- understand manner thereby assisting the practicing engineer in the choosing and evaluation of separation processes and facilitating the modeling and design of innovative equipment. A comprehensive reference list provides further opportunity for the following up of special separation problems. Chemical and mechanical engineers, chemists, physicists and biotechnologists in research and development, plant design and environmental protection, as well as students in chemical engineering and natural sciences will find this all-embracing reference guide of tremendous value and practical use.
Many things happen in nature reserves that are contradictory at first glance. For example, flower meadows are mown down during maintenance work, even though all the plants growing there are protected. Elsewhere, protected reed beds are burnt down in a fen or the top layer of soil is removed with bulldozers in a dune conservation area. Still other areas are to remain completely untouched by human intervention. The author Klaus-Dieter Hupke shows the different strategies of nature conservation. He also shows that nature conservation is mostly not exactly what the term says in essence: "protection of nature". On the contrary, in Central Europe nature conservation areas are predominantly the relics of old agricultural and thus cultural landscapes. Often, aesthetic aspects of a landscape section are also in the foreground when designating it as a natural monument or nature reserve. Moreover, nature conservation runs the risk of becoming a substitute action and an alibi for a still growing destruction of traditional and near-natural landscape systems in Central Europe as well as globally. The updated second edition now explicitly includes the consequences of climate change for nature conservation and has also incorporated a stronger reference to Austria as well as to the central Alpine region in some places for the relevant readers.
