State-dependent processing of Dentate Gyrus granule cell activity in-vivo
(2020-12-16)
The ability to form dissimilar neural activity patterns from similar sensory driven inputs is a phenomenon found in all vertebrates, called pattern separation. In mammals, pattern separation is closely related to a subregion ...
From galaxies to the cosmic web and back: the interplay of different scales in galaxy formation and cosmic reionization
(2020-10-08)
The evolution of the Universe is primarily governed by gravity, that triggers the development of a complex web-like distribution of galaxies. The latter are embedded in larger structures, called haloes, mainly composed by ...
Die Phyllosphäre als Lebensraum für Bakterien: Mechanismen der Interaktion epiphyller Bakterien mit der pflanzlichen Kutikula
(2020-12-16)
Die Phyllosphäre stellt einen lebensfeindlichen Lebensraum dar. Jedoch gibt es epiphytisch lebende Bakterien, die diesen Lebensumständen entgegenwirken und Mechanismen entwickelt haben, in diesem kargen Lebensraum Nährstoffe ......
Analyzing the Role of CyFIP2 in the Mouse Brain
(2020-06-19)
An important regulator of neuron outgrowth, growth cone motility and dendritic spine formation is the actin nucleator ARP2/3, a protein complex that functions in forming branched actin networks. ARP2/3 complex activity is ...
Efficient Algorithms for Routing a Net Subject to VLSI Design Rules
(2020-12-17)
In this thesis we consider detailed routing, an important step in the design of integrated circuits. On large instances detailed routing requires packing millions of node-disjoint Steiner trees into a graph with hundreds ......
Probabilistic and differential geometric methods for relativistic and Euclidean Dirac and radiation fields
(2020-07-09)
The main objective of the thesis is to study relativistic and Euclidean Fermionic quantum fields from a geometrical and probabilistic point of view as opposed to the standard treatment which is more algebraic in nature.
Gradient Flows, Metastability and Interacting Particle Systems
(2020-06-19)
Many stochastic models exhibit a phenomenon called metastability. The first goal of this thesis is to study this phenomenon for certain classes of interacting particle systems. The second goal of this thesis is the following. ...
Analytic Bipedal Walking with Fused Angles and Corrective Actions in the Tilt Phase Space
(2020-12-15)
As humanoid robots start to move from research labs to workplace environments and homes, the topic of how they should best and most reliably locomote in the face of unknown disturbances will be a topic of increasing ...
Geriatrische Medikationsanalyse für Pflegeheimbewohner durch öffentliche Apotheken
(2020-05-18)
Pflegeheimbewohner sind häufig von Polymedikation und damit einhergehenden arzneimittelbezogenen Problemen (ABP) betroffen. Medikationsanalysen können die Angemessenheit der Medikation bei Älteren verbessern. Mit der ...
Accumulation and Clearing of Ions in Circular Electron Accelerators
(2020-09-02)
Modern sychrotron light sources have to provide stable storage for electron beams with high charge densities to make brilliant synchrotron radiation available to users. Since requirements on the brilliance of the radiation ...
