Model inference and uncertainty quantification in complex resistivity imaging
(2026-06-19)This thesis contributes to the solution of the complex resistivity imaging (CRI) problem by introducing an inversion workflow that emphasizes accurate model inference and uncertainty quantification in a probabilistic ... -
Titanocene-Catalyzed Hydrosilylation of Cyclic Ethers to Stereochemically Enriched Anti-Markovnikov Alcohols and Fatty Alcohols
(2026-06-19)In this thesis, titanocene-catalyzed hydrosilylations are investigated as tools towards pharmaceutically relevant motifs. First, this work establishes a straightforward approach to stereochemically enriched <em>anti-Mark ... -
From Encounters to Guidance: Privacy-Preserving Risk Modeling on Temporal Contact Networks for Proactive Digital Contact Tracing
(2026-06-19)COVID-19 highlighted the promise and limits of digital contact tracing. Decentralized deployments protected privacy, but alerts were reactive, binary, and often triggered broad quarantines. Network-based targeting can ... -
Warm Inner Envelopes of Massive Star-Forming Regions
(2026-06-19)High-mass stars play crucial roles in the evolution of galaxies, but their formation process is still not fully understood. Our work investigates this topic by studying the warm inner gas envelopes around high-mass ... -
Deciphering the role of locus coeruleus for hippocampus-dependent learning and its impairment in a mouse model of Alzheimer's disease
(2026-06-18)The locus coeruleus (LC) is a key neuromodulatory nucleus and the brain's main source of norepinephrine. It is involved in a wide range of functions, notably, memory processing. Alzheimer's disease (AD) is a progressive ... -
Phenanthrazin-verknüpfte π-konjugierte Donor-Akzeptor-Systeme
(2026-06-18)Im Rahmen der vorliegenden Arbeit wurden neuartige H-förmige Donor-Akzeptor Strukturen synthetisiert und vollständig charakterisiert. Diese Strukturen dienten als Modellsysteme für optoelektronische Eigenschaften. <br/> Der ... -
Synthesis of Trityl-based Spin Systems and Investigation of Spin-Spin Interactions for Quantum Information Science
(2026-06-18)Quantum information science and molecular magnetism rely on precise control and understanding of spin-spin interactions in multi-spin systems. The exchange coupling constant J, which governs the magnetic interaction between ... -
Near-Optimum Circuits for Binary Addition and Multi-Output And Functions
(2026-06-17)In this thesis we present theoretical and practical work on the optimization of Boolean functions in chip design. On a chip, complex Boolean functions are built from basic building blocks computing for example an AND. For ... -
'Blue health' for healthy aging? Urban blue spaces as potentially therapeutic landscapes for older people in Ahmedabad and Ruhr Metropolis
(2026-06-17)In recent decades, increasing scientific evidence has emerged demonstrating the health benefits of exposure to surface waters called "blue spaces" in analogy to green spaces. Those health benefits mainly relate to positive ... -
Learning Perception and Manipulation of Objects in Cluttered Environments
(2026-06-17)Robots are increasingly deployed to operate autonomously in cluttered, everyday environments such as homes, warehouses, or retail spaces. In such settings, robust manipulation requires more than isolated grasping or motion ... -
DATCON: FPGA-based data reduction for the Belle II Pixel Detector
(2026-06-16)<strong>DATCON</strong>, the Data Acquisition Tracking and Concentrator Online Node, is a system of 15 FPGAs at the Belle II detector at KEK in Tsukuba, Japan. As part of the data acquisition (DAQ) chain, its task is to ... -
