The use of organocatalysts able to photocatalyze an organic reaction is a rapidly growing field. These photocatalyzed transformations are more environmentally sustainable with respect to the use of expensive/toxic metal-based photocatalysts. Based on the authors extensive experience in photogenerated intermediates, this book presents an overview on photocatalyzed organic processes having a synthetic significance, where an organic molecule functions as the photocatalyst. After a brief introduction defining the nature and the characteristics of a photo-organocatalyst (POC), the chapters are organized according to the class of POC used, as detailed below. Each chapter begins with a summary of the photophysical characteristics of the POCs and is followed by selected examples of synthetic applications. The last two chapters are devoted to the applications of photo-organocatalysis in polymerizations and to flow photo-organocatalysis. These in-depth explanations and practical applications make this title an essential reading for any chemistry student interested in organic (sustainable) synthesis.

The study of heavy-tailed distributions allows researchers to represent phenomena that occasionally exhibit very large deviations from the mean. The dynamics underlying these phenomena is an interesting theoretical subject, but the study of their statistical properties is in itself a very useful endeavor from the point of view of managing assets and controlling risk. In this book, the authors are primarily concerned with the statistical properties of heavy-tailed distributions and with the processes that exhibit jumps. A detailed overview with a Matlab implementation of heavy-tailed models applied in asset management and risk managements is presented. The book is not intended as a theoretical treatise on probability or statistics, but as a tool to understand the main concepts regarding heavy-tailed random variables and processes as applied to real-world applications in finance. Accordingly, the authors review approaches and methodologies whose realization will be useful for developing new methods for forecasting of financial variables where extreme events are not treated as anomalies, but as intrinsic parts of the economic process.
