• Sommario/riassunto: This book provides a compilation of mathematical-computational tools that are used to analyze experimental data. The techniques presented are those that have been most widely and successfully applied to the analysis of physiological systems, and address issues such as randomness, determinism, dimension, and nonlinearity. In addition to bringing together the most useful methods, sufficient mathematical background is provided to enable non-specialists to understand and apply the computational techniques. Thus, the material will be useful to life-science investigators on several levels, from phys

• Sommario/riassunto: The ceremonial centers of the Syro-Hittite city-states (1200-700 BC) were lavishly decorated with large-scale, open-air figurative reliefs - an original and greatly influential artistic tradition that has captivated the imagination of its contemporaries as well as that of modern scholars. This volume explores how Syro-Hittite monumental art was used as a powerful backdrop to important ritual events, and it opens up a new perspective by situating the monumental heritage in the context of ; large public performances and civic spectacles of great emotional impact. The first part of the volume focuses on the sites of Carchemish and Zincirli, offering a close reading of the relevant archaeological contexts. The second part of the volume discusses the embedment of monumental art in ritual performance and examines how change in art relates to change in ceremonial behavior, and how the latter relates in turn to change in power structures and models of rulership.
