Computational Studies on the Volume of Activated Tissue in Deep Brain Stimulation, Prof. Dr. Ursula van Rienen, Universität Rostock

06.09.2018 ab 17:00

Technische Fakultät, Gebäude D, Kaisterstraße 2, Aquarium

Abstract

Deep Brain Stimulation (DBS) is a widely used neuronal stimulation therapy for movement disorders like Parkinson’s disease and dystonias. Simulation studies can help for a deeper understanding of this therapy and, in future, for a patient-specific therapy planning aiming to prevent side effects as well. On the other hand, simulations can help e.g. to optimally select stimulation parameters in animal models.

The dielectric properties of biological tissue are based on experimental data and are subject to uncertainty, which arises from difficulties associated with the measuring process such as electrode polarisation at low frequencies, changes in the conditions of the tissue samples post mortem, and inter-individual variations. Based on the current state of measurement techniques for the dielectric properties of biological tissue, it can be assumed that uncertainty in these measurements and the resulting tissue properties will be a non-negligible factor, which has to be considered in computational models of bio-electrical applications.

In this contribution, we will introduce to the simulation pipeline to compute the Volume of Tissue Activated for a human model including uncertainty quantification and show some exemplary simulation results.

Nanopharmaceuticals - (nano)partikuläre Darreichungsformen für den Respirationstrakt?!, Prof. Dr. Regine Scherließ (Antrittsvorlesung)

12.07.2018 von 15:00 bis 15:30

Großer Hörsaal Pharmazie, Gutenbergstraße 76

Abstract

"Nano" ist schon seit geraumer Zeit ein Schlagwort, das sowohl verführerisch klingt wie auch kritisch beäugt wird. Dabei werden Nanostrukturen in der Technik und Medizin nicht erst seit der "National Nano Initiative" des National Institute of Health (NIH) in den USA im Jahr 2000 untersucht und eingesetzt. Mit dem neuen Jahrtausend hat aber das öffentliche Interesse an "Nano" und die Verbreitung von Nanotechnologien deutlich zugenommen. Im Rahmen der Vorlesung wird beleuchtet, was "Nano" im (pharmazeutisch-)technologischen Zusammenhang bedeutet und welche besonderen Eigenschaften Nanostrukturen mit sich bringen können. Nanotechnologien finden sich schon in einer Reihe von Arzneimitteln, den "Nanopharmaceuticals", wieder, wobei diese meist für die parenterale oder perorale Gabe gedacht sind. Im Respirationstrakt werden Nanopartikel häufig zunächst mit toxikologischen Überlegungen (Feinstaub, Rußpartikel) in Verbindung gebracht – aber auch dort können durch nanopartikuläre Formulierungen spezielle Wirkungen erzielt werden. Die Vorlesung wird einige dieser Möglichkeiten aufzeigen und erläutern, wie nanopartikuläre Systeme effektiv in den Respirationstrakt appliziert werden können.

To Catch a Thief, Dr. Giselher Herzer, Vacuumschmelze GmbH & Co. KG, Hanau

10.07.2018 ab 17:00

Technische Fakultät, Gebäude D, Kaisterstraße 2, Aquarium

Abstract

Retailers lose billions of Euros per year to shoplifters. Department store detectives and video cameras are therefore increasingly being assisted by electronic article surveillance (EAS). Hundred thousands of such systems are meanwhile installed and millions of disposable security labels are being produced on a daily base. Basically all EAS-systems operate on the same principle: Articles are affixed with security labels which, if not deactivated at the cash register, respond to electromagnetic fields generated from pedestals at the store's exits. The response is picked up by an antenna in the pedestals, thereby triggering an alarm. Today’s security labels are disposable items which are also used to secure inexpensive articles. Moreover, EAS labels are increasingly integrated directly into products or packaging during the manufacturing or packaging process. One major requirement therefore is that the labels are small and cheap. Further requirements are that the labels are reliably detectable and deactivatable and, as one of the major requests, that they cause no false alarms.

One of the most wide-spread EAS systems is based on magnetoelastic sensors which represent the latest and most sophisticated technology. The sensor element is a short magnetostrictive amorphous alloy ribbon which is housed in a small cavity such that it can vibrate freely. It is excited by magnetic field pulses to longitudinal, resonant vibrations. Once an exciting tone burst is over, the mechanical vibrations ring down exponentially over a time period of several milliseconds, hereby inducing a characteristic voltage in the receiver antenna while the exciting field is off. The detection electronics traces these echo voltages and triggers alarm if it recognizes the typical characteristics (like resonant frequency and ring-down time) of the resonator.

The talk surveys the physics behind magnetoelastic EAS labels and illustrates how to customize the sensor material by appropriate alloy design and thermal treatment.

Particle Physics after the Higgs Discovery: Where do we go? (Prof. Dr. Thomas Mannel, Siegen)

26.06.2018 ab 16:15

Hans - Geiger - Hörsaal (LS13 - R.52) des Physikzentrums

Abstract

After the recent discovery of the Higgs boson the so-called Standard Model of particle physics has become a complete and mathematically consistent theory, which – at least in principle – could be valid up to extremely high energies. In this talk I will discuss, why research in particle physics is still well motivated, although the Higgs boson is discovered. I will consider on the one hand the theoretical problems of the standard model, on the other hand, I will discuss experimental hints, why the standard model cannot be the final theory of the fundamental interactions.

RF NEMS Magnetoelectric Sensors (Northeastern University, Boston)

18.06.2018 von 17:15 bis 18:00

Technische Fakultät, Gebäude D, Kaisterstraße 2, Aquarium

Abstract

The coexistence of electric polarization and magnetization in multiferroic materials provides great opportunities for realizing magnetoelectric coupling, including electric field control of magnetism, or vice versa, through a strain mediated magnetoelectric coupling in layered magnetic/ferroelectric multiferroic heterostructures [1-9]. Strong magnetoelectric coupling has been the enabling factor for different multiferroic devices, which however has been elusive, particularly at RF/microwave frequencies. In this presentation, I will cover the most recent progress on new integrated magnetoelectric materials, magnetoelectric NEMS (nanoelectromechanical system) based sensors and antennas. Specifically, we will introduce magnetoelectric multiferroic materials, and their applications in different devices, including: (1) novel ultra-compact RF NEMS acoustic magnetoelectric antennas immune from ground plane effect with < l0/100 in size, self-biased operation and potentially 1~2% voltage tunable operation frequency; and (2) ultra-sensitive RF NEMS magnetoelectric magnetometers with ultra-low noise of ~1pT/Hz1/2 at 10 Hz for DC and AC magnetic fields sensing. These novel magnetoelectric devices show great promise for applications in compact, lightweight and power efficient sensors and sensing systems, ultra-compact antennas and for radars, communication systems, biomedical devices, IoT, etc.

Imidazolate Frameworks Potsdam and Hydrogen-bonded Supramolecular Networks, Prof. Dr. Hans-Jürgen Holdt (Universität Potsdam)

ICE CUBE and the Discovery of High-Energy Cosmic Neutrinos (Prof. Dr. Francis Halzen, University of Wisconsin)

12.06.2018 ab 16:15

Hans - Geiger - Hörsaal (LS13 - R.52) des Physikzentrums

Abstract

The IceCube project has transformed a cubic kilometer of natural Antarctic ice into a neutrino detector. The instrument detects more than 100,000 neutrinos per year in the GeV to PeV energy range. Among those, we have isolated a flux of high-energy cosmic neutri-nos. I will discuss the instrument, the analysis of the data, the signi-ficance of the discovery of cosmic neutrinos, and the recent multi-messenger observation of a flaring TeV blazar in coincidence with the IceCube neutrino alert IC170922. The large cosmic neutrino flux observed implies that the Universe’s energy density in high-energy neutrinos is the same as that in gamma rays, suggesting that the sources are connected and that a multitude of astronomical objects await discovery.

Cells and tissue as active materials (Prof. Dr. Ulrich Schwarz, Heidelberg)

04.06.2018 von 16:00 bis 16:45

Technische Fakultät, Gebäude D, Kaisterstraße 2, Aquarium

Abstract:

Biological systems such as cells and tissue use non-equilibrium processes to actively generate mechanical stress, movement and growth. Some of these processes can actually be reconstituted in biomimetic experiments with active soft matter. In this talk, we first discuss why and how contractile forces are generated by biological systems and how they can be measured, for example on soft elastic substrates. We then discuss how these contractile systems can be mathematically described by classical continuum mechanics extended by active elements. We finally explain how the local contractility of cells and tissue can be controled with optogenetics, and how the resulting forces and flows can be used to estimate their material properties.

Wires, trusses and pillars produced by assembly of plasma generated nanopartices (Prof. Dr. Ulf Helmersson, Linköping University, Schweden)

29.05.2018 ab 16:15

Abstract

Nanoparticles generated or supplied to a plasma attains a negative potential due to the nature of the plasma. This open up interesting possibilities in synthesis and assembly of the nanoparticles creating structures in the nano- and micro-range. In this work, we use hollow cathode sputtering powered with high-power pulse to ensure close to full ionized of the source material. This promotes rapid growth of the nanoparticles to desired sizes and the negative charge makes it possibility to guide nanoparticles for assembly and collection on desired positions. This is demonstrated by attracting na-noparticles to substrate positions with a positive potential and focusing nanoparticles through a matrix of electrostatic lenses to assemble the nanoparticles into pillars. For ferromagnetic nanoparticles, we also demonstrate generation of nanowires as well as nanowires cross-linked into trusses. Since the iron nanoparticles are generated under relatively pure condition they assemble into wires without oxides in the interfaces. Nanowires and trusses assembled on conducting substrates can potentially be used as low cost large area electrodes.

Acoustic wave lab-on-chip is now flexible, bendable and potentially wearable! (Prof. Richard Fu, Newcastle)

28.05.2018 von 17:15 bis 18:00

Institute Ostufer, Geb. D, "Aquarium", Kaiserstr. 2, 24143 Kiel

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.

Plasma Potential Distribution and Electron Heating in Sputtering Magnetrons (Prof. Dr. A. Anders, Leibniz Institute of Surface Engineering)

08.05.2018 ab 16:15

Hans - Geiger - Hörsaal (LS13 - R.52) des Physikzentrums

Abstract

Sputtering magnetrons are widely used to make thin films and are generally consid-ered a mature technology. Over the last years it has become known that magnetrons show surprisingly rich physics based on plasma instabilities. Without these instabili-ties, magnetrons would generally not work. The energy needed to ionize atoms of the process gas and sputtered from the target is generallythought to be delivered by "hot" secondary electrons (Penning-Thornton paradigm). Recent theoretical [1], spectro-scopic [2], and probe data [3] however indicate that most of the electrons’ energy comes from the presheath, and is provided by localized electric fields concentrated at the edge of "ionization zones" or "spokes" [4, 5]. This is closely related to self-organization and turbulence as observed in interesting images of magnetron plasmas.

Biomagnetic Sensing and Processing – Progress Using a Modular Approach, Dr. Tilmann Sander-Thömmes (PTB, Berlin)

23.04.2018 ab 17:15

Technische Fakultät, Gebäude D, Kaisterstraße 2, Aquarium

Open Talk of the CRC 1261 "Magnetoelectric Sensors: From Composite Materials to Biomagnetic Diagnostics"

In the field of biomagnetism the application of mathematical algorithms has been as important as the hardware itself. Traditionally, the hardware (the sensor Array) was based on superconducting quantum interference devices (SQUIDs) and operated for decades without large modifications. In contrast to that the range of relevant mathematical algorithms increased at a steady pace. This was driven by factors such as an ever increasing PC based computing power, new physiological insights motivating the application of existing algorithms, and the development of new algorithms to test biophysical models among others.

After around three decades of SQUID based Hardware, now new magnetic field sensors with the potential to replace or complement SQUIDs are available or under development. The opportunity for new sensors is the consequence of clinical challenges unsolved by state-of-the art SQUID based systems and due to new technology allowing alternative quantum physics based sensors in a small sized housing. These new sensors often have extra capabilities compared with SQUIDs and naturally some disadvantages. I will illustrate the modular approach using the example of optically pumped magnetometers and the signal processing toolbox FieldTrip.

Short biography
Tilmann Sander-Thömmes studied Physics at University of Freiburg and ETH Zürich and graduated there in 1992. He continued to obtain a PhD in solid-state physics at Imperial College in London. Following two post-docs in Berlin he has been working at Physikalisch-Technische Bundesanstalt since 2000 in the laboratory for Biosignals. Since 1998 he is involved with measuring and analysing magnetic brain signals. He is an expert in magnetoencephalography using both SQUIDs and more recently optically pumped magnetometers.

Applying Quantum Sensors, Prof. Dr. Jörg Wrachtrup (Institute for Quantum Science and Technology, University of Stuttgart)

08.03.2018 ab 17:00

Technische Fakultät, Gebäude D, Kaisterstraße 2, Aquarium

Open Talk of the CRC 1261 "Magnetoelectric Sensors: From Composite Materials to Biomagnetic Diagnostics"

The accuracy of measurements is limited by quantum mechanics. Ingenious demonstrations, like measuring gravitational fields or time have explored accuracy limits and reached fundamental obstructions. Yet, precision measurements so far are restricted to dedicated environmental conditions essentially excluding “every day” applications. In the talk I will discuss spin quantum sensors comprising a single or multiple electron spins. With such a system we measure a variety of quantities including electric and magnetic fields, temperature, and force under ambient conditions. We use nuclear spins to enhance the measurement accuracy of the electron spin e.g. via quantum error correction or as ancillary quantum bits as memory or for quantum Fourier transformation [1-3]. I will present a variety of applications ranging from quantum simulations to imaging of cellular structures. I will emphasize the engineering challenges of these sensors and discuss their use to e.g. measure biomagnetic fields.

Recent Progress on Distributed and Stochastic Optimization for Power Systems (Timm Faulwasser, KIT)

12.02.2018 von 17:15 bis 18:00

Institute Ostufer, Geb. D, "Aquarium", Kaiserstr. 2, 24143 Kiel

Abstract

The increasing need for the de-carbonization of energy supply calls for new operational methods for power systems. In this context, tailored system and control approaches are pivotal- The specific challenges include the consideration of volatile renewable generation, uncertain forecasts thereof, and highly nonlinear system behavior.

In this talk, we focus on the so-called Optimal Power Flow (OPF) problem, which refers to a class of large-scale non-convex steady-state optimization problems frequently arising in power systems. For example, OPF problems provide optimal set points for power dispatch that satisfy the power flow equations and technical limitations such as generation and/or transmission limits. However, OPF problems are highly non-convex and subject to considerable uncertainties, which includes forecasts of renewable generation and household consumption, line parameters and grid topology.

After a concise problem statement, we provide an overview of the state of the art techniques to considering uncertainties in OPF problems and their bottlenecks. Moreover, we will discuss the concept of Polynomial Chaos Expansions (PCE) which allows to consider non-Gaussian uncertainties in OPF problems. PCE builds upon a series expansion of random-variables. We will present recent results on PCE for convex DC-OPF problems and non-convex AC-OPF problems [1, 2]. Moreover, we will comment on the quantification of PCE truncation errors [3].

Due to their large-scale nature, the distributed solution of OPF problems is subject to considerable research efforts. Thus, we will also comment on our recent results on the distributed solution of OPF problems [4].

Quantum-Gas Microscopes - Quantum-Simulation with Single-Particle Access (Stefan Kuhr, Glasgow)

23.01.2018 ab 16:15

Hans - Geiger - Hörsaal (LS13 - R.52) des Physikzentrums

Abstract

Ultracold atoms in well-controlled engineered environments in optical lattices are a versa-tile tool for quantum-simulation of strongly correlated quantum systems. The most recent developments in this field include quantum-gas microscopes [1], enabling single-lattice-site resolution and single-atom control [2]. Imaging of with single-atoms resolution has made it possible to directly observe bosonic and fermionic many-body quantum systems in an un-precedented way, giving access to, e.g., in-situ measurements of temperature and entropy distributions, direct observation of correlations and their spreading, or the build-up of en-tanglement. I will present how we achieved single-atom-resolved fluorescence imaging of fermionic potassium-40 atoms using electromagnetically-induced-transparency (EIT) coo-ling [3], and a new way of Raman gray-molasses cooling [4]. I will also report on our pro-gress towards the creation of fermionic Mott insulators and the study of strongly correlated fermionic quantum systems and their out-of-equilibrium dynamics.

Über die zentrale Bedeutung des Plasmarandes für die Fusionsforschung (Prof. Dr. Ulrich Stroth, TU München/IPP)

16.01.2018 ab 16:15

Hans - Geiger - Hörsaal (LS13 - R.52) des Physikzentrums

Abstract

Der Votrag beschreibt die physikalischen Prozesse, die den Rand des Fusionsplasmas auszeichnen, wo der Übergang vin einem bis zu 100 Millionen Grad heißen Plasma zu den umgebenden matiellen Wänden vollzogen wird. Die Forschung auf diesem Gebiet ist stark interdisziplinär. Sie greift auf Konzepte aus verschiedenen Fachgebieten zurück, angefangen bei der Festkörperphysik, über die Atmo- und Molekülphysik und die Magnetohydrodynamik, bis hin zur Plasmaturbulenz. Durch die Darstellung ausgewählter Prozesse wird das Zusammenwirken der verschiedenen Einflüsse auf das Plasma sichtbar gemacht.
Das Verständnis des Plasmaranders ist insbesondere dazu notwendig, um eine sichere Leistungabfuhr aus Fusionsplasmen zu gewährleisten. Mögliche Realisierungendes Plasmarandes für ein Fusionskraftwerk werden beispielhaft and den Experimenten des MPI für Plasmaphysik, dem Tokamak ASDEX Upgrade und dem Stellarator Wendelstein 7-X, dargestellt.

Nanocrystals in Materials and Life Science Applications (Prof. Weller, Uni Hamburg)

Abstract:


Nanocrystals are already used for many applications in technical products for every day life. The talk will describe actual developments such as quantum dots in display and lighting technology and ultra-hard nanocomposite materials. Modern aspects of particle synthesis will be discussed.
The key idea for using nanocrystals for biomedical diagnostics is to benefit from their outstanding physical properties in the visualization of biological events or malignant cells or tissues. This requires a special design of the ligand shell, which preserves the fluorescent, magnetic and plasmonic properties of the particles in the biological environment on one side and allows a specific targeting on the other. The lecture reports on different chemical approaches and describes factors determining the biological response on fully synthetic nanocrystals. We will highlight concepts based on PEGylation and show how small deviations in the ligand shell alter the behavior in biological environment substantially. Moreover, we will present combinatorial approaches for the functionalization of the nanocrystals with biological affinity molecules to improve targeting specificity and concepts to optimize the physical properties of the inorganic core to increase the sensitivity for the respective imaging techniques.

Microplasma arrays: Concept, configuration, characteristics and potential applications (Dr. Volker Schulz-von der Gathen, Bochum)

07.11.2017 ab 16:15

Leibnizstr. 13, Hans-Geiger-Hörsaal, 24118 Kiel

Abstract:

Microplasma arrays belong to the class of low temperature non-equilibrium atmospheric pressure plasma devices. They consist of huge numbers of about 100 micrometer size cavities regularly positioned on a common ground. These structures are usually generally manufactured applying microstructure techniques on silica wafers [1], but other configurations have been investigated recently. Being basically dielectric barrier discharges, the devices are typically driven by a single power supply at kHz frequencies at voltages of a few hundred volts. Due to the small dimensions strong fields exist in close contact with the surfaces that introduces new physical features. The geometric configuration results e.g. in unique features of discharge dynamics as ionization waves. A huge number of possible applications have been proposed over the last years [2]. The examples range from photonic applications as light generation and detection to large scale surface treatments or use as meta materials. In this talk we will give a basic description of the concepts of microplasma arrays, their operation and some application possibilities. Subsequently we will describe some of the physical features observed mainly by analysis of optical emission.

Electrification of chemical industry: a key role for plasma chemistry (Dr. Gerard van Rooij, Dutch Institute for Fundamental Energy Research DIFFER, Eindhoven)

24.10.2017 ab 16:15

Leibnizstr. 13, Hans-Geiger-Hörsaal, 24118 Kiel

Abstract:

Sustainable energy generation by means of wind or from solar radiation through photovoltaics or concentrated solar power will continue to increase its share of the energy mix. Intermittency due to e.g. day/night cycle, regional variation in availability, and penetration of sustainable energy into sectors other than electricity such as the chemical industry necessitates means of storage, transport and energy conversion on a large scale. A promising option is the synthesis of chemicals and artificial fuels using sustainable energy. A truly circular economy requires that the raw materials are the thermodynamically most stable ones such as CO_2 and N_2 . In this contribution it will be highlighted how plasma chemistry can potentially combine compatibility with e.g. intermittency and localized production to activate these molecules with maximum energy efficiency, essentially due to preferential vibrational excitation (causing inherently strong out-of-equilibrium processing conditions that achieve selectivity in the reaction processes). Examples will be discussed of research carried out at DIFFER to ultimately enable a scale up to chemical industrial applications.

Spin electronics for biomagnetic recordings (Dr. Myriam Pannetier-Lecoeur)

12.10.2017 ab 17:00

Technische Fakultät, Gebäude D, Kaisterstraße 2, Aquarium

Talk of the CRC 1261 "Magnetoelectric Sensors: From Composite Materials to Biomagnetic Diagnostics". Everybody interested is welcome.

Abstract

Currents circulating in excitable cells like neurons or nerve fibers may be measured by the radiated magnetic field. At the organ level, these magnetic fields can be detected by non-invasive experiments using highly sensitive magnetometers such as SQUIDS, atomic magnetometers or mixed sensors, the latter using spin electronics. To understand the genesis of the signals obtained in brain areas, it is relevant to investigate the fields generated at the level of one or few cells. This requires small and sensitive field sensors, operating at physiological temperatures, which has long been out of reach from existing technologies. Spin electronics, based on thin film magnetic properties, explores the variation of conduction electron transport as a function of the state of their spin. It is thus possible to modify the resistance of an element as a function of the magnetic field of its environment. This property has been widely exploited in hard disk drive heads, but also opens up the possibility of manufacturing very sensitive and miniaturizable magnetic sensors. Spin electronics-based magnetic sensors are micron-size devices reaching sub-nanotesla field range on a wide range of temperature, including physiological temperature. We have designed and fabricated magnetic sensors called magnetrodes, as a magnetic equivalent of electrodes, to probe locally the information transmission of excitable cells. These probes contain one or several GMR elements in embodiment compatible to recordings in contact with tissues or within tissues. Two types of sensors have been evaluated on living tissues; a planar probe to investigate the Action Potential propagation in in vitro preparation of muscle cells, which have demonstrated the first local biomagnetic recordings with GMR sensors, and a sharp probe for in vivo recordings of cortical activity. In this talk I will present how sensors based on spin electronics can address biomagnetic signal recordings at the organ level and at local scale. In particular I will discuss the first in vivo experiments performed, which have paved a new way to a local description of electrical activity, without direct contact to the cell and which allow accessing not only the amplitude of the activity but also its direction of propagation, at any depth within the tissues.

Physiology of Peripheral Nerve Conduction from a Signal Analysis Point of View (Prof. Dr. med. Wilhelm Schulte-Mattler)

14.09.2017 ab 17:00

Technische Fakultät, Geb. D, "Aquarium", Kaiserstr. 2, 24143 Kiel

Talk of the CRC 1261 "Magnetoelectric Sensors: From Composite Materials to Biomagnetic Diagnostics". Everybody interested is welcome.


Abstract

To transmit information, peripheral nerve fibers locally change their electrical membrane properties. The changed regions move along the fibers causing traveling electrical fields, causing changes in voltage over time that depend both on where the voltage is recorded and on the nerve’s properties. Things are complicated by the nerves being composed of many thousands of fibers.

A simple model that explains these voltage changes, namely the signals that are recorded from actively transmitting nerves, will be presented. These signals provide information about the nerve’s function. Both, the influence of the recording conditions and the influence of various nerve disorders on the recorded waveforms will be presented. The usefulness of simple measures, such as amplitude and duration, is established. More advanced signal analysis indeed provides more information about peripheral nerve disorders.

Short biography

Wilhelm Schulte-Mattler studied Mathematics and Physics, followed by Medicine. He graduated at the University of Würzburg in 1988. His thesis was on Quantification of recruitment in needle-EMG. He specialized in Neurology in 1993. After heading Clinical Neurophysiology in the Dept. of Neurology, University of Halle-Wittenberg; since the year 2000, he is head of Clinical Neurophysiology in the Dept. of Neurology, University of Regensburg. A significant part of his work is on waveform analysis in clinical neurophysiology, particularly in electromyography and in electroneurography.

Novel Molecular Beam Epitaxy Approach for High Quality Complex Oxide Films, Dr. Bharat Jalan

01.09.2017 ab 10:00

Technische Fakultät, Geb. D, "Aquarium", Kaiserstr. 2, 24143 Kiel

Abstract:

Complex oxides with ABO3 perovskite structure have been of scientific interests for a long time due to their ability to display a wide-range of phenomena. Recent advances in thin film growth approaches have enabled the growth of this material class in thin film and heterostructure forms with structural quality, which has now become similar to that of the conventional semiconductors. However the grand challenge in the field is to obtain these materials with the high level of stoichiometric and defect control. In this talk, we will present our group’s effort to address these challenges and to utilize stoichiometry defects as a new degree of freedom to control material’s physical phenomena using a novel hybrid molecular beam epitaxy (MBE) approach with the focus to understand and control novel electronic and magnetic ground states in defect-managed oxide thin films and heterostructures.

A Family of Crouzeix-Raviart Non-Conforming Finite Elements in Two- and Three Spatial Dimensions (Prof. Sauter, Zürich)

21.07.2017 von 14:15 bis 15:45

Institut für Informatik, Ludewig-Meyn-Straße 2, 24118 Kiel, Raum: Übungsraum 2/K

Abstract:

In this talk we will present a family of non-conforming "Crouzeix-Raviart" type finite elements in two and three dimensions. They consist of local polynomials of maximal degree p on simplicial finite element meshes while certain jump conditions are imposed across adjacent simplices.

We will prove optimal a priori estimates for these finite elements. The characterization of this space via jump conditions goes back to the seminal paper of Crouzeix and Raviart in 1973. However, the definition is implicit and the derivation of an explicit representation of the local basis functions for general p in 3D was an open problem.

We present explicit representations for these functions by developing some theoretical tools for fully symmetric and reflection symmetric orthogonal polynomials on triangles and their representation.

Finally we will analyze the linear independence of these sets of functions and discuss the question whether they span the whole non-conforming space. This talk comprises joint work with P. Ciarlet Jr., ENSTA, Paris and Charles F. Dunkl, Virginia Tech.

Generalized Convolution Quadrature (Prof. Fernández, Zürich)

18.07.2017 von 11:00 bis 13:00

Ludewig-Meyn-Str. 2. Raum Ü2/K (LMS2, R. Ü2/K), 24118 Kiel

Speaker: 

Prof. Dr. María López Fernández, Universität Zürich

Abstract:


ubich's Convolution Quadrature is nowadays a well
established method for the time discretization of retarded potentials
associated to wave equations. It has been very much developed in the
last decade, both from the theoretical and the algorithmic point of
view. However, despite its nice properties, the Convolution Quadrature
is strictly restricted to the use of fixed time steps. In this talk I
will present the "generalized Convolution Quadrature", a new family of
methods designed to overcome the strong restriction to uniform
temporal grids. I will show stability and convergence estimates and
numerical results illustrating the good behaviour of the new method. I
will also outline the current limitations in the implementation of the

Approximating Geometric Knapsack via L-packings (Grandoni, Lugano)

07.07.2017 von 14:15 bis 15:45

Institut für Informatik, Ludewig-Meyn-Str. 2, Raum Ü2/K (LMS2, R. Ü2/K), 24114 Kiel

Speaker:  Prof. Grandoni, IDSIA USI-SUPSI in Lugano

Abstract:

In the 2-dimensional geometric knapsack problem (2DK) we are given a
set of n axis-aligned rectangular items, each one with an associated
profit, and an axis-aligned square knapsack. The goal is to find a
(non-overlapping) packing of a maximum profit subset of items inside
the knapsack (without rotating items). The best-known polynomial-time
approximation factor for this problem (even just in the cardinality
case) is 2 + ε [Jansen and Zhang, SODA 2004]. In this work we break
the 2 approximation barrier, achieving a polynomial-time 17/9 + ε <
1.89 approximation, which improves to 558/325+ ε < 1.72 in the
cardinality case.

Essentially all prior work on 2DK approximation packs items inside a
constant number of rectangular containers, where items inside each
container are packed using a simple greedy strategy. We deviate for
the first time from this setting: we show that there exists a large
profit solution where items are packed inside a constant number of
containers plus one L-shaped region at the boundary of the knapsack
which contains items that are high and narrow and items that are wide
and thin. The items of these two types possibly interact in a complex
manner at the corner of the L.

The above structural result is not enough however: the best-known
approximation ratio for the sub-problem in the L-shaped region is 2 +
ε (obtained via a trivial reduction to 1-dimensional knapsack by
considering tall or wide items only). Indeed this is one of the
simplest special settings of the problem for which this is the best
known approximation factor. As a second major, and the main
algorithmic contribution of this work, we present a PTAS for this
case. We believe that this will turn out to be useful in future work
in geometric packing problems.

We also consider the variant of the problem with rotations (2DKR),
where items can be rotated by 90 degrees. Also in this case the
best-known polynomial-time approximation factor (even for the
cardinality case) is 2 + ε [Jansen and Zhang, SODA 2004]. Exploiting
part of the machinery developed for 2DK plus a few additional ideas,
we obtain a polynomial-time 3/2 + ε-approximation for 2DKR, which
improves to 4/3 + ε in the cardinality case.

Learning Sparse Binary Features for Medical Image Segmentation of the Abdomen (Heinrich, Lübeck)

07.07.2017 von 14:15 bis 15:45

Institut für Informatik,Christian-Albrechts-Platz 4, R.715, 24114 Kiel

Speaker: Jun.-Prof. Dr. Mattias Heinrich, Uni Lübeck

Abstract:


In this talk, we explore the capabilities of sparse binary features for medical image segmentation. Due to insufficient contrast and anatomical shape variations local image patches rarely provide sufficient information for accurate segmentation of abdominal structures. Based on our two recent MICCAI papers, we propose to use long-range binary features to robustly capture the image context. Two different classification strategies are subsequently developed. 

First, a very fast approximate nearest neighbour search based on vantage point forests and Hamming distances between feature strings is presented. The classifier can be learned and applied to new data in few seconds. The approach reaches state-of-the-art performance for larger organs on the VISCERAL3 benchmark.

Second, we develop a deep neural network architecture that combines a local CNN path with a new contextual path that encodes the sparse binary features. Following the ideas from Network-in-Network, 1x1 convolutions are employed to learn the best combination of different binary offset locations. We demonstrate experimentally that this restricted feature extraction in the first layer enables to regularise the network with a huge receptive field and leads to short training times of less than 10 minutes. Using only 1 million trainable parameters, the model achieves a accuracy of 64.5% Dice, which is comparable to the best performing, much more complex deep CNN approach for pancreas segmentation.

Finally, the potential use of learned binary features for other tasks in medical image analysis, such as image registration and disease classification will be discussed.

Eberhard Möbius (New Hampshire): Astronomy with Neutral Atoms

Abstract
 

Eberhard Möbius (Space Science Center and Department of Physics, University of New Hampshire):
Astronomy with Neutral Atoms - Imaging the Heliospheric Boundary and Catching the Interstellar Wind with the Interstellar Boundary Explorer

400 years after Galileo pointed a telescope at celestial objects for the first time, neutral atoms were added to the astronomical toolbox with the Interstellar Boundary Explorer (IBEX), launched October 19, 2008. Since early 2009, two energetic neutral atom (ENA) cameras take global images of the solar system’s interaction with its galactic neighborhood. They have returned stunning images of the heliospheric boundary region, where the solar wind slows down in response to the surrounding interstellar medium, including the front and tail region of the heliosphere. Most unexpectedly, the images show a bright and persistent “Ribbon” across the sky, which provides a marker for the direction of the local interstellar magnetic field, but the processes leading to the bright ENA emission are still being investigated. Time variations in the ENA fluxes that vary with energy provide additional constraints and point to the neutral solar wind that penetrates beyond the boundary of the heliosphere. The IBEX-Lo camera catches the interstellar wind of neutral H, He, O, and Ne atoms that blows through the solar system with a speed of ≈26 km/s and arises from the motion of the Sun relative to the surrounding local interstellar gas cloud (LIC). This observed gas flow distribution is an excellent probe of the state of the LIC and shows clear signatures of the deflection of the interstellar plasma at the heliospheric boundary.

23.06.2017 von 13:00 bis 15:00

Institute Ostufer, Geb. D, "Aquarium", Kaiserstr. 2, 24143 Kiel

Abstract:

Electric machine design paradigms have been dramatically changed by the need to meet the demands for minimizing losses and smooth torque control during driving cycles with widely vary loads and speeds.  Simultaneously, new drive control paradigms systematically out-perform industry standard field oriented control (FOC) and simultaneously solve several classical problems with FOC. In addition, the internet of things is opening expansive opportunities for motor drives.  This presentation with focus on these disruptive changes in the paradigms for electric machines and electrical drives and explore the opportunities for innovation that these technologies provide.

Tiberiu Minea (Paris-Sud): Modeling of vacuum breakdown

13.06.2017 ab 17:15

Hans-Geiger-Hörsaal ( Leibnizstr. 13, Raum 52)

Abstract


Tiberiu Minea (Paris-Sud): Modeling of vacuum breakdown. Thermo-field, dynamics of microparticles and laser assisted electron emission

Vacuum is often used as an isolator in numerous applications, such as X-ray tubes, particle accelerators, high voltage pass-through, etc. However, their performance is limited by the risk of unpredictable breakdown events between electrodes. Moreover, the breakdown usually leads to the formation of arc discharges, which can seriously damage the system.

Since 2010 the LPGP develops a research program “High Voltage holding In Vacuum”, in collaboration with CEA and CentraleSupelec which aims to give a better description of the origin of the vacuum breakdown.

Three numerical models have been developed to tackles three particular aspects of the problem.

(i) The model OVIP (Orsay Vacuum Insulation Percolation) deals with the thermos-field electron emission from a surface microprotrusion and the results are in good agreement with the experimental results for breakdown. The operation with fast pulses allows to enhance the field emission avoiding the breakdown.

(ii) The model OFEN (Orsay Field Emission Nanoparticles) describes the micro-particles (MP) transport in the inter-electrodes gap, in vacuum) and the interactions (heating and modification of the MP charge) between electrons and the MP. It is an extension of the Cranberg’s theory of clumps when the MP is exposed to an intense field ~1-5 MV/m and it is simultaneous bombarded by electrons released from the cathode micro-tips. The results clearly show four different regimes of MP trajectories obtained for different emission currents, MP sizes and inter-electrode distances and the effect of the MP crash of on the cathode, helping to understand the vacuum conditioning.

(iii) The last model OFELIE (Orsay Field Emission and Light Emission) analysis the electron emission induced by picosecond laser from solid surfaces placed under an intense electric field. The results show an important difference between the electrons temperature (5500 K) and the phonons temperature (850 K). In these conditions, the Fermi-Dirac distribution depends of the electron temperature, while the thermo-field emission becomes effective for temperatures well below the fusion of the metal.

In conclusion, the modeling of the related phenomena between solid and vacuum depends on the way the energy is transferred to the electrons and it helps to distinguish between different scenarios and to design performant systems.

Prof. Herbert Jäger (Jacobs University Bremen): An introduction to Reservoir Computing

12.06.2017 von 17:15 bis 18:45

Institut für Elektrotechnik und Informationstechnik, Geb. D, "Aquarium", Kaiserstr. 2, 24143 Kiel

Abstract

 

Recurrent neural networks (RNNs) are general approximators for nonlinear dynamical systems and have recently become widely used in the "deep learning" field of machine learning, especially for speech and language processing tasks. For instance, Google's speech recognition and language translation services are based on RNNs.

However, the deep learning set-ups for RNN training are computationally very expensive, require very large volumes of training data, and need high-precision numerical processing. For such reasons, deep-learning variants of RNNs are problematic in fields where training data are scarce, where fast and cheap algorithms are desired, or where noisy or low-precision hardware is to be used. This is often the case in domains of nonlinear signal processing, control, brain-machine interfacing, or biomedical signal processing.

Reservoir Computing (RC) is an alternative machine learning approach for RNNs which is in many aspects complementary to the ways of deep learning. In RC, a large, random, possibly low-precision and noisy RNN is used as a nonlinear excitable medium - called the "reservoir" - which is driven by an input signal. The reservoir itself is not adapted or trained. Instead, only a "readout" mechanism is trained, which assembles the desired output signal from the large variety of random, excited signals within the reservoir. This readout training is cheap - typically just a linear regression. RC has become a popular approach in research that aims at useful computations on the basis on unconventional hardware (non-digital, noisy, low-precision).

The talk gives an introduction to the basic principles and variants of RC. Numerous examples will be presented according to wishes from the audience.

07.06.2017 ab 18:30

Atlantic Hotel, Raiffeisenstraße 2, 24103 Kiel

Abstract
 

The development of multifunctional bioactive materials for tissue engineering and regenerative medicine will be discussed, summarizing the progress made and the remaining challenges for the future. The focus will be on bioactive glasses and their composites in combination with biodegradable polymers. A comprehensive overview about 3D scaffolds will be presented and key results on the development of (nanostructured) polymer-bioactive glass composite scaffolds will be discussed. Novel approaches involving the coating and infiltration of inorganic scaffolds by biodegradable polymers containing functionalized nanoscale particles or nanofibres for in-situ drug delivery will be introduced, as an attractive concept to merge tissue engineering and drug delivery approaches. To highligth the important advantage of bioactive glasses in comparison with other biomaterials, we will discuss how specific glass compositions doped with bioinorganics (biologically active ions) can induce favourable cell behaviour in relation to osteogenesis and angiogenesis. In this context, the vascularisation potential of a new family of bioactive scaffolds incorporating and releasing such metallic ions will be discussed and the current challenge in the field, e.g. the development of vascularised tissues, will be demonstrated based on recent in vivo results. Areas of future research in the field of biomaterials for engineering (complex) tissue interfaces, e.g. osteochondral defects, and for wound healing and soft tissue regeneration will be discussed introducing the concept of cell encapsulation and biofabrication (processing with cells in bioinks). Finally, the author’s views about the challenges ahead will be presented, focusing on open issues that must be tackled to translate current laboraory based tissue engineering approaches to clinical settings.

Prof. Tamas Kerekes (Aalborg): Design of residential Photovoltaic systems – a guideline

13.02.2017 von 17:15 bis 18:45

Technische Fakultät, Kaiserstr. 2, Raum: "Aquarium", Geb. D

Abstract:

Photovoltaic technology continues to increase its share in the global energy market, with an exceptionally fast growth in the last few decades reaching a cumulative capacity of 227 GW by the end of 2015, with a predicted extra 50GW of new installations for 2016. According to a report from SolarPower Europe (former European Photovoltaic Industry Association (EPIA)), the price of PV systems has decreased more than 75% in the last 10 years, making PV cost competitive with fossil-based generation in several countries. Fueled by this strong cost reduction, the PV industry is transitioning from being driven by subsidies into a viable option for investment for both large power plants and residential installations on a pure cost competition basis. Residential PV systems are a key element in the success story of PV rooftop installations and large utility scale plants share about 50% of new installations today. ENTSO_E forecasts that by 2025 European power generation will have over 50% renewable, where solar will be expected to have a major role. If we combine the solar increase with even more wind penetration, then this will require a much more flexible system in order to make the best use of renewable energy sources when they are available. Among the different flexibility options, storage is one solution that allows to respond quickly to balancing needs by absorbing the excess solar generation at peak times and releasing it during periods of lower production, but high load demand. By making the best use of cheap renewable electricity when it is available, storage can make the energy system more cost-effective. By adapting to demand and limiting the possibility of peak pricing, storage will also have a balancing effect on prices throughout the day. If solar is combined with storage then this will act as a bridging technology between the electricity, heating and cooling as well as transport sectors. Besides the rapidly developing battery storage capacity, the electrification of the transport sector and the use of electricity for heat purposes allow for an integrated approach of the energy system. This will provide new opportunities for European consumers and businesses, whilst potentially offering a variety of services to grid operators.

Axel Gross (Ulm): Challenges in the theoretical description of electrochemical energy storage and conversion

31.01.2017 ab 12:15

Max-Planck-Hörsaal (LS13-R.8), Physikzentrum

Abstract:

In spite of its technological relevance in the energy conversion and storage, our knowledge about the microscopic structure of electrochemical electrode-electrolyte interfaces and electrical double layers is still rather limited. The theoretical description of these interfaces from first principles is hampered by three facts:

  1. In electrochemistry, structures and properties of the electrodeelectrolyteinterfaces are governed by the electrode potential which adds considerable complexity to the theoretical treatment since charged surfaces have to be considered.
  2. The theoretical treatment of processes at solid-liquid interfaces includes a proper description of the liquid which requires to determine free energies instead of just total energies. This means that computationally expensive statistical averages have to be performed.
  3. Electronic structure methods based on density functional theory (DFT) combine numerical efficiency with a satisfactory accuracy. However, there are severe shortcomings of the DFT description of liquids, in particular water, using current functionals.


Despite these obstacles, there has already significant progress been made in the first-principles modeling of electrochemical electrode-electrolyte interfaces. In this contribution, I will present our attempts to contribute to this progress by systematically increasing the complexity of the considered systems [1]. Different approaches to describe aqueous electrolytes at electrodes using first-principles calculations will be compared: the electrolyte can be described either as a thermodynamic reservoir or using implicit of explicit solvent models [2,3]. The equilibrium coverage of specifically adsorbed anions such as halides will be addressed which is an integral part of the realistic modeling of electrochemical double layers [2]. Furthermore, the modelling of electrocatalytic reactions occurring in fuel cells [3] will be presented. Finally, first attempts to model structures and processes in batteries using electronic structure calculations will be presented.
