The focus of this thesis are synchronization phenomena in networks and their intrinsic control through time delay, which is ubiquitous in real-world systems ranging from physics and acoustics to neuroscience and engineering. We encounter synchronization everywhere and it can be either a helpful or a detrimental mechanism. In the first part, after a survey of complex nonlinear systems and networks, we show that a seemingly simple system of two organ pipes gives birth to complex bifurcation and synchronization scenarios. Going from a 2-oscillator system to a ring of oscillators, we encounter the intriguing phenomenon of chimera states which are partial synchrony patterns with coexisting domains of synchronized and desynchronized dynamics. For more than a decade scientist have tried to solve the puzzle of this spontaneous symmetry-breaking emerging in networks of identical elements. We provide an analysis of initial conditions and extend our model by the addition of time delay and fractalconnectivities. In the second part, we investigate partial synchronization patterns in a neuronal network and explain dynamical asymmetry arising from the hemispheric structure of the human brain. A particular focus is on the novel scenario of partial relay synchronization in multiplex networks. Such networks allow for synchronization of the coherent domains of chimera states via a remote layer, whereas the incoherent domains remain desynchronized. The theoretical framework is demonstrated with different generic models.

This volume studies high and late medieval material culture in a Pan-European context. The idea of ‘unity of culture’ in Medieval Latin Europe is well known in historical texts, especially when it concerns the so-called ‘Europe North of the Alps’. This book investigates the similarities and differences in material culture between areas, regions and political entities and opens the dialogue for a more interregional discussion.The editors acknowledge that there are numerous challenges in understanding the phenomenon the volume addresses, the fundamental one being defining (or even redefining) a common material culture of Europe. Important in determining this is greater appreciation of how objects reflect interactions between peoples, both local and foreign, which can be driven by a variety of factors, including trade, conflict and diplomacy etc. But just as important is observing the differences between ‘things’ across Europe, reflecting developments and transformations its cultural, social and economic history. These works are traditionally presented in isolation or at the local level, maybe even in very specialized tomes, as often it is thought their observation are not relevant to wider discourses. Conversely, what is clear, however, is that by interconnecting these seemingly introvert studies of specific artefact types or sites etc., readers can better appreciate the similarities and differences in material culture across Europe. This book is of interest to researchers in archaeology and material culture.

Offering a groundbreaking interdisciplinary perspective, this book explores the fundamental mechanisms behind music perception by bridging music psychology with computational neuroscience. It models how adaptation and synchronization shape neural responses to music, revealing insights unattainable through traditional brain localization theories. By applying complex systems theory, it shifts the focus from isolated brain regions to dynamic network interactions, providing a holistic and predictive framework with relevance across a broad spectrum of natural sciences. Ideal for researchers across musicology, psychology, neuroscience, as well as complexity and computational science, it opens new paths for understanding the brain’s response to music through scientific precision and cross-disciplinary integration.
