Label-Free Measurements of Amyloid Formation by Suspended Microchannel Resonators
(2014-12-12)Amyloid deposition in tissues is a hallmark of many severe diseases including Alzheimer’s and Parkinson’s disease. The formation of amyloid fibrils involves several intermediate steps, and revealing the kinetics of each ... -
Langperiodische magnetotellurische Messungen auf der oberflächennahen Leitfähigkeitsanomalie in der Münchberger Masse: Hinweise auf eine graphitisierte Überschiebungsfläche durch dreidimensionale Modellrechnungen
(2002-10-08)The electrical conductivity of the earth can be much higher in fractures than in the rock. Therefore the investigation of an area with high conductivity provides much knowledge about ... -
Lanthanide Doped Wide Band Gap Semiconductors: Intra-4f Luminescence and Lattice Location Studies
(2004-03-03)The doping of semiconductors with lanthanides is a promising way to realize light emitters, their luminescence arising from radiative electron transitions within the 4f shell of the triply ... -
Large Eddy Simulationen von isolierten Scheibengalaxien
(2014-12-18)In this thesis I present a newly developed, dynamical model for the turbulent, star-forming interstellar medium on scales of some ten parsecs, which is named MIST (Multi-phase Interstellar medium model with Star formation ... -
Large eddy simulations of compressible magnetohydrodynamic turbulence
(2017-02-13)Supersonic, magnetohydrodynamic (MHD) turbulence is thought to play an important role in many processes — especially in astrophysics, where detailed three-dimensional observations are scarce. Simulations can partially fill ... -
Large scale resistivity surveys combining magnetic and magnetotelluric observations
(2006-09-18)Electromagnetic methods allow investigations of subsurface conductivity structures. This work focuses on electromagnetic array data (38 measuring sites) covering an area of 900x600 square ... -
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 ... -
Laser Frequency Combs for High Resolution Spectrograph Calibration
(2021-10-28)While laser frequency combs (LFCs) are in principle ideal calibration light sources for high resolution spectrographs, they are still not regularly used. This is not only due to high cost and maintenance, but also persistent ... -
Laser nitriding of metals:Influences of the ambient pressure and the pulse duration
(2002-03-01)Laser nitriding of metals such as iron, stainless steel, aluminum or titanium is an interesting phenomenon both in physics and industry. On a time scale of hundreds nanoseconds, high intensity ... -
Laser-Carburisierung von Eisen und Edelstahl
(2006-01-20)This work reports on excimer laser irradiation of pure iron and austenitic stainless steel in methane atmospheres. The laser-material-interaction plays a basic role enabling a substantial ... -
Laserinduzierte Änderungen der elektronischen Transporteigenschaften von Manganaten
(2017-07-31)This thesis investigates the influence of local excitations by ultra-short laser pulses in strongly correlated manganites. It focuses on the nonlinear transport properties which are connected to the correlations between ... -
Leaflet-resolved localization and diffusion of molecules within membranes using metal-induced energy transfer
(2022-05-10)Diffusion is the most fundamental process of molecular transport in cell membranes and an important factor in maintaining its fluidity, controlling the dynamics and functioning of the membrane. In-depth knowledge of membrane ... -
Learning and Memory Strategies in Evolving Environments
(2022-01-17)Storing memory of molecular encounters is vital for an effective response to recurring external stimuli. Interestingly, memory strategies vary among different biological processes. These strategies range from networks that ... -
Legacy cross-section measurements of the $t\bar{t}Z$ production process in the trileptonic final state at $\sqrt{s}=13\,$TeV with the ATLAS detector
(2024-01-31)After three years of data-taking during the second run of the LHC at CERN, Geneva, Switzerland, the ATLAS detector has recorded its most extensive proton-proton collision data set to date, allowing for a wide range of ... -
Length scales in granular matter
(2013-04-24)Jammed packings of granular materials differ from thermal systems normally described by statistical mechanics. In recent years a statistical mechanics of static granular media has emerged by using the volume of the system ... -
Lepton production in ice by scattering of astrophysical neutrinos at high energies
(2005-11-18)Ultra-high energy cosmic-ray protons have been observed, and hence the existence of corresponding neutrinos of astrophysical origin is believed to be guaranteed. Due to flavor oscillations ... -
