Fast and Robust Multi-Dimensional Cardiac Magnetic Resonance Imaging
(2020-09-02)Magnetic Resonance Imaging (MRI) has become an almost indispensable tool in hospitals worldwide as it provides significant and unique information for the assessment of various disease and injuries. However, MRI is an ... -
Feature Selectivity in Synthetic Neuronal Networks
(2024-06-06)A fundamental property of neurons in the primary visual cortex is their preference for orientation of edges. In primates and carnivores orientation selective neurons are organized into functional domains that are arranged ... -
Feature-based attention in primate visual cortex
(2016-07-06)The scope of this thesis, after a brief summary of the core ideas of top-down attentional control is given (Chapter 2.1), is to shed some light on the cortical control circuit underlying the deployment of feature-based attention. ... -
Flows, morphology, and memory: study of a living network
(2020-06-22)The complex behaviour of the slime mould Physarum polycephalum, a simple eukaryote, has been puzzling researchers since its discovery. The giant unicellular, but multinucleate organism is highly successful at tackling ... -
Fluctuations and Oscillatory Instabilities of Intracellular Fiber networks
(2015-11-10)Biological systems with their complex biochemical networks are known to be intrinsically noisy. The interplay between noise and dynamical behavior is particularly relevant in the case of chemotactic amoeboid cells as their ... -
Fluorescence correlation spectroscopy for studying intermediate filament assembly
(2017-08-10)Intermediate filaments play a central role in the cytoskeleton of eukaryotic cells. Together with microtubules and actin filaments they determine the mechanical properties of cells. Microtubules are also the guiding tracks ... -
Fluorescence Lifetime Single Molecule Localisation Microscopy
(2021-03-26)In conventional fluorescence microscopy, species are distinguished by colour. While these images provide an abundance of information about the sample, they are, in many aspects limited by artefacts and resolution, and some ... -
Fluorescence spectroscopic studies of protein conformational dynamics
(2013-10-31)The folding of a protein into its native structure is the fundamental prerequisite for its functionality. The polypeptide chain itself contains the chemical information necessary for spontaneous folding of the protein. ... -
Food Distribution in Ant Colonies: Trophallaxis and Self-Organization
(2017-09-14)Roughly one hundred million years ago, solitary insect species evolved social interactions that enabled the formation of colonies. A main reason for this advance was their ability to feed each other with previously ... -
Force information integration in the primate fronto-parietal reach network
(2023-11-10)The primate sensorimotor system relies on force predictions, when executing a motor command with a certain force. Yet it remains unclear if the sensorimotor system uses these force predictions to prepare a motor command ... -
Forces in Cellular Growth and Division
(2016-02-05)Under confinement cell populations exert growth forces onto their surroundings. Confined cell populations can be found plentiful in nature, e.g. tumors embedded in healthy tissues, microbial populations in stone cavities ... -
Foundations of Stochastic Thermodynamics
(2015-03-17)Small systems in a thermodynamic medium --- like colloids in a suspension or the molecular machinery in living cells --- are strongly affected by the thermal fluctuations of their environment. Physicists model such ... -
From annotation to bacterial data models
(2022-06-24)Science and technological advancements walk side-by-side and with the recent emergence of novel high throughput techniques, the necessity to have specialized data structures to host and represent the complex and high variety ... -
From hearing to singing:sensory to motor information processing in the grasshopper brain
(2016-08-02)Grasshoppers, and among them especially the species Chorthippus biguttulus, have been used as a model system to study the neuronal basis of acoustic behavior. Auditory neurons have been described from intracellular recordings. ... -
From inside-out to outside-in: cortical lamination development in the Reelin-deficient neocortex
(2019-03-15)The adult mammalian neocortex is divided into six vertical layers, as well as into numerous specialized tangential areas that are defined by distinct cytoarchitectures and specific wiring patterns. Precise neocortical ... -
From Paramagnetic Proteins to Field Alignment of Small Molecules
(2022-03-17)In this dissertation we show how to push the boundaries of structure elucidation using tensorial NMR parameters. Possible sources for these effects are paramagnetic centers or molecular alignment, and they contain valuable ... -
From screening to function - Evolutionary conservation of novel JAK/STAT signal transduction pathway components
(2007-04-03)Signal transduction pathways mediating the exchange of information between cells are essential for development, cellular differentiation and homeostasis. Their dysregulation is also frequently ... -
From vision to action: Hand representations in macaque grasping areas AIP, F5, and M1
(2014-12-19)Grasping and manipulating objects of different shapes is a fundamental feature of the primate hand. This skill requires the transformation of visual object information into corresponding hand actions. In the primate brain ... -
Fullerene-Nitroxide Derivatives as Potential Polarizers for Dynamic Nuclear Polarization (DNP) in Liquid State
(2016-09-12)Nuclear magnetic resonance spectroscopy and imaging (NMR/MRI) are widely applied methods for non-destructive analysis of biological systems, materials and medical applications. Dynamic nuclear polarization (DNP) is a method ... -
Function and homeostasis of non-proteinogenic amino acids in Bacillus subtilis
(2024-07-23)The gram-positive soil bacterium Bacillus subtilis lives in a constantly changing environment, requiring rapid adaptation to survive and thrive. This forces the bacteria to adapt to nutrient availability or stressful ...
