The platform economy is gaining increasing importance. Digital platforms can be found in more and more areas of consumers' daily lives. One area particularly affected by this is online shopping, which is becoming increasingly popular. Large online retailers have achieved monopolistic positions, and the majority of online shopping takes place on their marketplaces. This presents significant challenges for manufacturer brands. Recently, some of them have started operating their own platforms to counteract the risks within the platform economy, the so-called Brand Flagship Platforms.

Le frère dominicain Jérôme Savonarole partage avec Machiavel l’étrange privilège d’être affecté d’une légende noire, celle d’un « fou de Dieu » qui a imposé à Florence à la fin du XVe siècle une « féroce dictature morale ». Savonarole ne renvoie plus à un personnage historique singulier mais à la façon dont son exemple a été repris dans l’histoire, qui se résume à une réforme fanatique des mœurs et à l’établissement d’une théocratie.

New fabrication techniques and biomaterials have advanced significantly as attention toward healthcare innovations in recent decades has increased. This book provides a comprehensive overview of the application of additive manufacturing for biomedical devices. The book focuses on the use of biomaterial for hard and soft tissue engineering. These materials can imitate the mechanical, structural, and biological characteristics of the parent tissue, repairing or replacing its functioning. It provides details on the use of various biomaterials for different biomedical applications. It highlights the present trends and potential of various techniques and materials for various applications. The chapters in this book written by eminent experts highlight recent developments in additive manufacturing for biological mimicking and surgical planning. It discusses latest advances in various 3D printing technologies in the fabrication of biomedical devices for orthopaedic and cardiovascular applications, along with rising trends in designing and creating tissue replacement substitute simulants. This book can serve as a fundamental textbook for research in additive manufacturing, fabrication of implants or scaffolds and medical device development, biomaterials, tissue engineering, and biomedical engineering. This book can be a valuable resource for mechanical and biomedical engineers, academicians, healthcare researchers, and professionals interested in tissue engineering.

To ultimately address this serious issue, this book begins with the nonlinear dynamic characteristics of marine plankton, focusing on the dynamic behavior of both two-dimensional and spatiotemporal patterns. As a critical foundation of marine ecosystems, the frequent outbreaks of marine phytoplankton and the toxicity of planktonic animals pose significant threats to marine ecological security and human health. One of the primary reasons we currently struggle to effectively manage the safety issues surrounding marine plankton is the extremely complex nature of their growth environment, which exhibits intricate dynamic and nonlinear characteristics. By constructing reaction-diffusion models and fractional diffusion systems of the planktonic ecosystem, the book characterizes the various factors in different environments and studies the nonlinear behavior of marine organisms. Employing linear stability theory, multi-scale analysis, comparison principle, analytical techniques, and the construction of Lyapunov functions, the book delves into the following topic: the stability of the plankton ecosystem, Hopf bifurcation, Turing bifurcation and other local bifurcations, spatial self-organization behavior of marine plankton, the formation of spatiotemporal patterns, and the persistence and extinction properties and characteristics. Marine ecology and the marine environment are currently hot research topics internationally, with the behavior of marine organisms being a core area of this research. The goal of exploring these issues is to scientifically understand the features of marine organisms, control their behavior, manage ocean pollution effectively, contribute to human development, and support social advancement. Additionally, the authors aime to make academic contributions and provide guidance to graduate students and researchers dedicated to this field.

This book explains the most important technical terms and contents and assigns them to the corresponding areas. It also includes seemingly peripheral areas that play a role in information security. For instance, the topic complexes of functional Safety and Privacy are examined in terms of their similarities and differences. The book presents currently used attack patterns and how to protect against them. Protection must be implemented on both a technical level (e.g., through the use of cryptography) and on an organizational and personnel level (e.g., through appropriate management systems and awareness training). How can one determine how secure data is? How can relevant threats be identified that need protection? How do risk analyses proceed?

This book covers lignin, a renewable source of carbonaceous material derived from biomass, which is a subject of research, development and innovation in both academia and industry.

TEX has always been regarded as the most elegant and powerful system for computer typesetting. However, its widespread use beyond academia was hampered by its complexity. Recently, fairly good TEX implementations have come out for PC's putting TEX on the disks of many people including writers, designers, desktop publishers, and engineers. Consequently, interest in TEX has surged. What is needed at this point is a book that teaches step-by-step how to use TEX, illustrating each step with relevant examples. This is exactly what S. v. Bechtolsheim's book does. It is a tutorial and guide for the first-time user of TEX, as well as a reference for the more experienced "TEXpert." TEX in Practice will appear as a four volume set, starting with TEX in Practice, Volume 1: Basics; TEX in Practice, Volume 2: Paragraphs, Math and Fonts; TEX in Practice, Volume 3: Tokens, Macros; TEX in Practice, Volume 4: Output Routines, Tables. TEX in Practice will be an indispensable reference for the TEX community and a guide through the first step for the TEX novice.
