Titel: A simple excitable model reveals how brain network topology shapes neural activity patterns
Abstract: Brain networks are characterized by a number of distinctive topological features, such as a
heterogenous degree distribution with hubs, hierarchically organized modules, as well as a
characteristic spectrum of motifs and cycles. These features have consequences for various aspects
of brain dynamics, such as self‐sustained network activity, the wave‐like propagation of activations as
well as correlations and anti‐correlations of activity patterns. In a series of recent studies we have
demonstrated that the relation between neural network topology and dynamics can be
systematically investigated with the help of a simple, but powerful excitable (cellular automaton)
model which facilitates a mechanistic understanding of the contributions of different topological
features of brain networks to brain dynamics.

Titel: Sensing the Nanoscale with Optoplasmonics
Abstract: Nanophotonic device building blocks, such as optical nano/microcavities and plasmonic nanostructures, lie at the forefront of sensing and spectrometry of trace biological and chemical substances. My laboratory is developing a new class of nanophotonic architectures by combining optically resonant dielectric nano/microcavities with plasmonically resonant metal nanostructures to enable detection at the nanoscale with extraordinary sensitivity. Initial demonstrations include single-molecule detection and even single-ion sensing. The coupled photonic-plasmonic resonator system promises a leap forward in the nanoscale analysis of physical, chemical, and biological entities. I will review our work in this burgeoning field of optoplasmonic biosensors. I will also talk about our most recent advances in localising light at the nanoscale in disordered 2D photonic crystals.

Titel: Flow-induced Noise in Hydroacoustic Sensor Systems
Abstract: Sound can propagate over a large distance in the sea without significant attenuation and is therefore of unique importance in underwater communication, navigation, and detection. Underwater sound is received in these applications with hydroacoustic sensor systems that are often attached to or towed behind a vessel. The turbulent flow that forms around the hull of the moving sensor system induces hydroacoustic noise in the interior that dominates the noise level (and therefore limits the performance) at larger speeds due to the strong speed dependence of flow acoustic sources (e.g. Lighthill’s v8-law). In a series of research cruises in recent years the statistical properties and underlying physical mechanisms of interior hydroacoustic noise induced from outer turbulent flows have been investigated under sea conditions with towed measurement systems. The talk will focus on the spatio-temporal correlation of the turbulent noise sources as well as the filter properties of the mechanical hull structure and the embedded hydrophones. The analysis is predominantly performed in wavenumber-frequency space. New developments in piezoelectric thin-film sensor technology allow in principle the design of specific wavenumber filters for flow noise reduction. The potential of such sensors for future underwater applications is discussed.

Titel: Acoustic wave lab-on-chip is now flexible, bendable and potentially wearable!
Abstract: Thin film acoustic wave devices especially surface acoustic waves (SAW) have been used for sample preparation (sorting, separating, mixing, nebulization and dispensing) as well as bio-sensing. This talk will focus on our recent work of flexible and wearable thin film acoustic wave lab-on-chip (mainly using ZnO and AlN films on flexible substrates) for acoustic wave based microfluidic applications. We report theoretical and experimental studies of the evolution, hybridization and decoupling of wave modes in the flexible acoustic wave devices, as well as their vibration patterns. thus providing a guide for different microfluidic applications. Thin film based flexible SAW devices have the potential to be integrated with other microfluidic and sensing technology on flexible substrates including CMOS integrated circuits to make novel lab-on-chip for bio-detection for wearable and flexible applications. SAW devices on commercial polymer and aluminum foils have been fabricated and various microfluidic functions, such as mixing, pumping, jetting have been demonstrated with bent and deformed acoustic wave devices.

Titel: „Datenschutz: Anbruch eines neuen Zeitalters? – Zur Geltung der EU-Datenschutzgrundverordnung ab dem 25. Mai"
Abstract: Ab dem 25.5.2018 haben alle Bürger, Behörden und Unternehmen neue Vorschriften zum Datenschutz zu beachten, denn dann gelten europaweit die Regelungen der „EU-Datenschutzgrundverordnung“ sowie in Deutschland ein Bundesdatenschutzgesetz, bei dem nicht ein einziger Paragraph so wie vorher geblieben ist. Darauf weisen seit Monaten nicht nur Datenschützer, sondern auch viele andere hin, wie z.B. Unternehmensberater, Rechtsanwälte und Zertifizierungsunternehmen wie der TÜV. Doch was wird sich ab Ende Mail tatsächlich ändern? Hat vor dem Hintergrund z.B. der drastisch erhöhten Sanktionen ein echtes Umdenken stattgefunden oder bleibt der Datenschutz eine ungeliebte bürokratische Bürde?

Titel: Multivariate Algorithms for Machine Scheduling Problems
Abstract: Machine scheduling problems are a long-time key domain of algorithms and complexity research. In those problems, we are generally given a finite set J of jobs with certain characteristics, and we must find a schedule for processing the jobs on one or more machines, which also may have their individual specifications. Typical characteristics of a job are its processing time, its release date, its due date, or its importance reflected by an integer weight. A significant amount of research has been devoted in the past 60 years towards designing polynomial-time algorithms which approximate the value of optimal schedules (for various objective functions). A novel approach to machine scheduling problems are multivariate algorithms, which aim to find a provably optimal schedule at the expense of an increased run time, which is permitted to depend moderately exponentially on the job characteristics or other structural parameters. We survey some recent algorithms in this paradigm, present some novel results, and discuss several challenging open problems in this exciting research area.
