Single cell visual psychophysics
Domdei, Niklas (2021-10-05)On the one hand, the eye is the human being’s window to the world. On the other hand the eye is a window to the human brain enabling noninvasive and in vivo assessment of nervous tissue. With adaptive optics scanning laser ... -
Single impurity atoms immersed in an ultracold gas
Spethmann, Nicolas (2012-06-20)In this thesis, experiments with an ultracold gas doped with few and single atoms of another species are presented.
The techniques to adequately prepare and manipulate an ultracold Rb gas and to dope it with a precisely ... -
Single molecule tracking with light sheet microscopy
Ritter, Jörg (2011-11-11)The work presented here concentrates on light sheet based fluorescence microscopy (LSFM) and its application to single molecule tracking.
In LSFM the sample is illuminated perpendicular to the detection axis with a ... -
Single optical microfibre-based modal interferometer
Karapetyan, Konstantin (2012-11-23)In this thesis, I report on the experimental investigation and the computer simulation of optical microfibre-based modal interferometers. An optical microfibre (OMF) can be produced from a commercial single-mode optical ... -
Single-top production t-channel cross section measurement in the electron+jets final state at ATLAS with 35 pb-1 of data
Khoriauli, Gia (2012-09-03)The cross section of the Standard Model electroweak production of a single top quark in the t-channel has been measured using the LHC proton-proton collision data at $sqrt{s}=7$ TeV, $35 {\rm pb}^{-1}$ of integrated ... -
Singular integrals and maximal operators related to Carleson's theorem and curves in the plane
Roos, Joris (2017-08-15)In this thesis we study several different operators that are related to Carleson's theorem and curves in the plane.
An interesting open problem in harmonic analysis is the study of analogues of Carleson's operator ... -
Singular propagators in deformation quantization and Shoikhet-Tsygan formality
Löffler, Johannes (2015-06-03)This thesis adds some details to the seminal approach to logarithmic formality and interpolation formality by Alekseev, Rossi, Torossian and Willwacher: We prove that the interpolation family of Kontsevich formality maps ... -
Singulärer N+/Si-Austausch im Molekülgerüst allosterischer Modulatoren vom Alkan-Bisammonium-Typ: Konsequenzen für die Interaktion mit muskarinischen Acetylcholin-Rezeptoren vom Subtyp M2
Albrecht, Marc (2005)Muskarinische Acetylcholin-Rezeptoren zählen zu den G-Protein gekoppelten Rezeptoren und besitzen neben der Acetylcholin-Bindungsstelle, die auch als orthosterische Bindungsstelle bezeichnet wird, ein weiteres spezifisches ... -
Site-Directed Spin Labeling of Large Riboswitches Using Click Chemistry
Kerzhner, Mark (2019-02-14)Due to the conformational variability of riboswitches, their structural analysis is of a great importance. The most frequently used techniques to investigate dynamic processes within the riboswitches are NMR and FRET. EPR ... -
Sleep and navigation in Drosophila
Flores-Valle, Andres (2023-12-20)Sleep plays an essential role in life and is critical for the optimal functioning of the brain, for example in learning and memory. Drosophila displays many of the signatures of sleep observed in mammals or humans, including ... -
Slow Atomic Beams Manipulation with Magnetic Videotapes
Mérimèche, Habib (2004)Laser cooling methods provide the possibility to obtain very well collimated and slow atomic beams. These intense sources have attracted new interest in the manipulation of atomic trajectories. Atom optical schemes based ... -
Small embeddings, forcing with side conditions, and large cardinal characterizations
Njegomir, Ana (2019-09-26)In this thesis, we provide new characterizations for several well-studied large cardinal notions. These characterizations will be of two types. Motivated by seminal work of Magidor, the first type characterizes large ... -
Small Molecules, Big Impact: Investigating Hydrides in the Interstellar Medium
Jacob, Arshia Maria (2021-06-16)This thesis investigates hydride molecules in the interstellar medium (ISM) and their use as diagnostics of different phases of the ISM. Particular emphasis is given to the central CH radical, a probe of diffuse and ... -
Small-scale Physical and Chemical Structure of Diffuse and Translucent Molecular Clouds along the Line of Sight to the Galactic Center
Thiel, Vivien (2019-05-02)Diffuse and translucent molecular clouds constitute a large part of the molecular interstellar medium (ISM) in our Galaxy as well as in other spiral galaxies. In particular, the envelopes of giant molecular clouds (GMCs), ... -
Small-scale studies of the Milky Way disc and halo gas with absorption-line spectroscopy
Nasoudi Shoar, Soroush (2012-12-13)Progressive studies in the last decades have shown that the interstellar medium (ISM) is more complex and dynamic than previously thought. The presence of the small-scale structures, structures on scales below 1 pc, has ... -
SMNrp und TUBA: Isolierung und Charakterisierung zweier neuer Gene mit Homologie zu SMN, dem Krankheitsgen der spinalen Muskelatrophie
Plöttner, Oliver (2002)Spinale Muskelatrophie, die zweithäufigste autosomal rezessive Erbkrankheit mit Todesfolge beim Menschen, wird durch Mutationen im SMN1-Gen verursacht, die zu einem Mangel an funktionellem SMN-Protein in den Zellen ... -
Smooth 4-Manifolds and Surface Diagrams
Behrens, Stefan (2014-06-18)Surface diagrams are a diagrammatic representation of smooth, 4-dimensional manifolds. In fact, a surface diagram encodes a 4-manifold together with a map onto the 2-sphere. After giving a detailed proof of this correspondence, ... -
Smoothed Analysis of Selected Optimization Problems and Algorithms
Brunsch, Tobias (2014-03-20)Optimization problems arise in almost every field of economics, engineering, and science. Many of these problems are well-understood in theory and sophisticated algorithms exist to solve them efficiently in practice. ... -
Soft tissue preservation in amber: a comparative study on the taphonomy and limits of fossilisation of resin embedded arthropods
Barthel, Hans Jonas (2022-11-02)This doctoral thesis deals with the limits of morphological and biomolecular preservation of fossils in amber and provides new information on their taphonomy. A particular focus lies on arthropod inclusions from Cambay and ... -
