Book Description
Conformal nets provide a mathematical model for conformal field theory. The authors define a notion of defect between conformal nets, formalizing the idea of an interaction between two conformal field theories. They introduce an operation of fusion of defects, and prove that the fusion of two defects is again a defect, provided the fusion occurs over a conformal net of finite index. There is a notion of sector (or bimodule) between two defects, and operations of horizontal and vertical fusion of such sectors. The authors' most difficult technical result is that the horizontal fusion of the vacuum sectors of two defects is isomorphic to the vacuum sector of the fused defect. Equipped with this isomorphism, they construct the basic interchange isomorphism between the horizontal fusion of two vertical fusions and the vertical fusion of two horizontal fusions of sectors.

Book Description
The first edition of Embryos, Genes and BirthDefects, edited by the late Peter Thorogood, was a radicalnew book aimed at bridging the gap between the medical disciplinesof embryology and dysmorphology, and recent advances in cellular,molecular and developmental biology. This new edition remainsunique in its breadth and brings up to date our understanding ofbirth defects and of the strategies utilized to gain suchknowledge. It features new chapters on human cytogenetics,mutagenesis and the eyes and ears. The book presents key topics in developmental biology andexplains how they provide the foundations for understandingclinical birth defects. The first six chapters introduce conceptsand strategies adopted to elucidate developmental anomalies leadingto birth defects. The book then focuses on specific organs andreviews the cellular and molecular mechanisms affecting theirdevelopment and how disruption of these mechanisms by genetic orenvironmental factors may underlie certain birth defects. Thechapters are concise and provide up-to-date coverage of topics in aformat that is easily accessible and yet at the forefront ofresearch. Written primarily for paediatricians, obstetricians, clinicalgeneticists and allied workers, this book guides the reader throughthe contribution of modern molecular biology to our understandingof human development. Developmental and cellular biologists willlearn how errors in the cellular and genetic mechanism can lead toclassical disorders, diseases and syndromes.

Book Description
Laser powder bed fusion of metals is a technology that makes use of a laser beam to selectively melt metal powder layer-by-layer in order to fabricate complex geometries in high performance materials. The technology is currently transforming aerospace and biomedical manufacturing and its adoption is widening into other industries as well, including automotive, energy, and traditional manufacturing. With an increase in design freedom brought to bear by additive manufacturing, new opportunities are emerging for designs not possible previously and in material systems that now provide sufficient performance to be qualified in end-use mission-critical applications. After decades of research and development, laser powder bed fusion is now enabling a new era of digitally driven manufacturing. Fundamentals of Laser Powder Bed Fusion of Metals will provide the fundamental principles in a broad range of topics relating to metal laser powder bed fusion. The target audience includes new users, focusing on graduate and undergraduate students; however, this book can also serve as a reference for experienced users as well, including senior researchers and engineers in industry. The current best practices are discussed in detail, as well as the limitations, challenges, and potential research and commercial opportunities moving forward. Presents laser powder bed fusion fundamentals, as well as their inherent challenges Provides an up-to-date summary of this advancing technology and its potential Provides a comprehensive textbook for universities, as well as a reference for industry Acts as quick-reference guide
