Data Analysis of Musical Timeseries
(2024-01-08)Music, despite its ubiquitous familiarity, is surprisingly hard to define. Should one consider its acoustic features, the mechanics by which it is produced and performed, as well as the cultural norms attached to them, ... -
Data-driven modelling of non-linear systems by means of artificial neural network hybrids
(2021-04-16)In the natural sciences, theory and experiment are in permanent interaction with each other. Experimental data provide impulses for new theories and theories suggest new experimental set-ups. Earlier, these two areas had ... -
Multimodal high-resolution mapping of contracting intact Langendorff-perfused hearts
(2021-01-21)The vital function of the heart during normal sinus rhythm relies on the spread of regular excitation waves within the cardiac muscle tissue, leading to an orderly contraction and efficient pumping action. These electrical ... -
Laser cavitation bubbles at objects: Merging numerical and experimental methods
(2020-12-10)The main body of this thesis deals with the existence of the so called fast jet that develops when a single, laser generated cavitation bubble expands and collapses close to a flat, solid boundary at normalised distances ... -
Collective Spiking Dynamics in Cortical Networks
(2020-10-14)Even though information processing in the cortex most likely emerges from the collective interplay of billions of neurons, even basic properties of collective dynamics in cortical networks are still not known with certainty. ... -
Towards a Statistical Physics of Collective Mobility and Demand-Driven Transport
(2018-05-29)Collective mobility and demand-driven transport systems are vital to proper, efficient and sustainable functioning of biological, technical and social systems. They are relevant to mastering several major transitions ... -
Intermittent Complexity Fluctuations during Ventricular Fibrillation
(2018-01-31)Ventricular fibrillation is a lethal cardiac arrhythmia that is one of the major causes of death worldwide. A prevalent treatment is the application of a high-energy shock using a cardiac defibrillator. These defibrillation ... -
Parameterschätzung und Modellevaluation für komplexe Systeme
(2016-10-17)Mathematical models in form of dynamical systems play an important role in many disciplines, such as system biology, engineering, or physics. They are widely used to simulate the time evolution of the internal states of ... -
Encoding of complex sounds in the auditory midbrain
(2015-06-16)How complex natural sounds such as speech and vocalizations are encoded in the main converging center of the auditory midbrain is not yet fully understood. For multi-units, which are composed of several single neurons, ... -
Neural Networks with Nonlinear Couplings
(2015-05-20)Cortical neural networks generate a ground state of highly irregular spiking activity whose dynamics are sensitive to small perturbations such as missing or additional spikes. A robust, reliable transmission of information ... -
Local- and Cluster Weighted Modeling for Prediction and State Estimation of Nonlinear Dynamical Systems
(2011-08-08)This thesis deals with black-box modeling techniques, in particular local models based on nearest neighbors, and Cluster Weighted Models, which combine a stochastic clustering of the input ... -
Modelling closed-loop receptive fields: On the formation and utility of receptive fields in closed-loop behavioural systems
(2010-05-28)In higher animals an increasingly complex hierarchy of visual receptive fields exists from early to higher visual areas, where visual input becomes more and more indirect. From there on ... -
The Time Course of Negative Priming
(2010-03-23)Selective attention enables goal-directed behavior despite the permanent, immense input to the sensory system. Contradicting early speculations of an active attending and passive ignoring, ... -
Mathematical Description of Differential Hebbian Plasticity and its Relation to Reinforcement Learning
(2009-11-18)The human brain consists of more than a billion nerve cells, the neurons, each having several thousand connections, the synapses. These connections are not fixed but change all the time. In order to describe synaptic ...
