Potassium Channel Simulation with Force Field Development and Enhanced Sampling
(2026-01-22)Potassium (K+) channels are a type of membrane protein that selectively permeates K+ ions. They play important roles in several biological processes, including regulating membrane potential, neuronal excitability, and ... -
3d Transition Metal-Catalyzed C–H Activation for Late-Stage Functionalization
(2026-01-22)Transition metal-catalyzed direct C–H activation has become a versatile platform for highly efficient and selective molecular transformations. Specifically, 3d transition metal catalysts, which are more earth-abundant and ... -
Unraveling ezrin's binding to PtdIns[4,5]P2 and F-actin in biomimetic systems
(2026-01-22)To fulfil manifold life-sustaining functions such as cell motility, maintenance of cell shape, and cell division, a thin layer of filamentous actin together with regulatory proteins beneath the plasma membrane is ... -
Measuring and Optimizing Peer-to-Peer Networks: A Case Study of the InterPlanetary File System
(2026-01-21)The Internet's transformation from a decentralized network of networks into a landscape dominated by centralized platforms has created systemic risks including infrastructure fragility, censorship vulnerabilities, and ... -
Study of Compact Multi-Planet Systems around M Dwarf Stars
(2026-01-21)In this thesis, the architecture and dynamics of two known compact multi-planet systems around M dwarf stars were investigated, in particular L 98-59 and YZ Ceti. These two systems are among the 28 closest M dwarfs to ... -
Generalised Diagonal Dimension and Roe-Like Algebras
(2026-01-21)In this dissertation, we introduce a generalised diagonal dimension and use it to compute the asymptotic dimension of a class of metric spaces via their C*-algebras of controlled-propagation operators. We discuss why the ... -
Development of Low-Order Scaling Multicomponent Methods
(2026-01-16)This work targets the development and application of low-order scaling multicomponent methods for efficient simulation of nuclear quantum effects (NQE) within complex systems. The awareness of NQEs is increasingly growing ... -
Advancing Differentially Private Deep Learning: Algorithmic Improvements and Performance Evaluation
(2026-01-16)In recent years, machine learning and deep learning technologies have been widely applied across various domains. However, the privacy concerns associated with these technologies have become increasingly prominent. In this ... -
Sedimentary Provenance Analysis from Methods to Application: Grain-Size Inheritance and the Miocene Geological Evolution of Northern Calabria
(2026-01-14)The sedimentary record is arguably one of the most valuable archives of Earth’s history. Sedimentary provenance analysis encompasses all aspects of sediment formation related to composition of the source-rock, topography, ... -
Conditional Stability and Instability Estimates for Inverse Random Source Problems
(2026-01-13)This thesis is motivated by the study of passive imaging problems. Such problems can be characterised as scattering problems under uncontrolled incident waves. We focus specifically on inverse random source problems, a ... -
Basement-Cover Relationships in the Dom Feliciano Belt
(2026-01-08)The interaction of the main cratons that constitute the present-day configuration of South America and Africa, together with several minor blocks, led to the amalgamation of Southwest Gondwana in the late Neoproterozoic, ... -
Single Step Genomics: Methods and Implementation in German Cattle Populations
(2026-01-08)Genomics and genomic technologies have significantly advanced the development of many plant and livestock populations. However, their impact on beef cattle populations, particularly in Germany, has been limited. This thesis ... -
Multi-layered proteogenomic characterization of mouse brain aging in physiology and disease
(2026-01-06)Functional decline and increased susceptibility to neurodegenerative disease are the result of a complex interplay of molecular changes that accompany brain aging. These changes include accumulation of cellular damage, ... -
Structural Complexity and Biomass of Mountain Forests in the Annapurna Region, Himalaya
(2026-01-06)Heterogeneous environmental conditions characterize mountain forests and can be highly dynamic due to climatic and socio-economic changes. Despite their importance, our understanding of forests in the Himalaya is limited, ... -
Food Consumption and Malnutrition: Machine Learning Applications and Agricultural Trade Analysis
(2026-01-06)Consumers’ nutritional health status is facing significant global challenges, including malnutrition, obesity, and overweight-related health risks. The persistent high consumption of meat further exacerbates resource ... -
A robust, automated nudged elastic band method in internal coordinates
(2025-12-18)In this work, a robust and reliable implementation of the Nudged Elastic Band (NEB) method is developed and tested. It is a method for finding reaction paths and TS, which can be used to theoretically compute reaction ... -
Sums with hyperbolic conditions
(2025-12-18)We develop a generalization of the hyperbola method, a technique used to obtain asymptotic estimates for summations involving a product of variables as a constraint, given that similar sums over rectangular regions can be ... -
