Approximate Inference Applications to Representation Learning and Stochastic Processes Problems
Ojeda Marin, César Ali (2021-04-07)The present dissertation dwells in the development of inference algorithms and methodologies for the study of dynamical datasets. We developed techniques to analyze time-series datasets for point processes, switching ... -
Approximation Algorithms for the Traveling Salesman Problem
Zhong, Xianghui (2021-05-11)The traveling salesman problem (TSP) is probably one of the best-studied problems in discrete optimization. Given a complete weighted graph with n vertices, the task is to find a tour of minimal length that visits every ... -
Approximation Algorithms for Traveling Salesman Problems
Traub, Vera (2020-04-15)The traveling salesman problem is the probably most famous problem in combinatorial optimization. Given a graph G and nonnegative edge costs, we want to find a closed walk in G that visits every vertex at least once and ... -
Approximation Complexity of Optimization Problems: Structural Foundations and Steiner Tree Problems
Hauptmann, Mathias (2004)In this thesis we study the approximation complexity of the Steiner Tree Problem and related problems as well as foundations in structural complexity theory. The Steiner Tree Problem is one of the most fundamental problems ... -
Approximations for Hierarchical and Lower-Bounded Clustering and the Complexity of Minimum-Error Triangulation
Arutyunova, Anna (2024-03-28)Clustering deals with the problem of finding structures in data. Given a number k we search for a good partition of a set of data points into at most k sets, where the sets of the partition are called clusters. In the ... -
Aptamer-mediated transactivation of transcription utilizing CRISPR/Cas9 and a photoreceptor
Renzl, Christian (2021-12-16)In synthetic biology, spatio-temporal control of molecular functions is an essential tool for the investigation and manipulation of cellular processes. The usage of light enables a reversible non-invasive trigger, that ... -
Aptamers for targeted activation of T cell-mediated immunity
Haßel, Silvana Katharina (2016-09-19)An attractive way of preventing or curing infections and diseases is to mobilize patient’s own defense mechanisms, the immune system. Treatments following this approach are commonly known as immunotherapies. The development ... -
Aptamerselektion zur Funktionsuntersuchung von zytosolischen Proteinen
Fucik, Katharina (2007)Zur biologischen Einordnung der CC-bindenden Proteine CYTIP und KIAA0403 einem auf Genomebene neu entdeckten Vertreter, wie auch FHL2, einem vielseitigen Ko-Transkriptionsfaktor, wurde die Aptamertechnologie zur in vitro ... -
The aqueous corrosion of borosilicate glasses studied in operando by in situ fluid-cell Raman spectroscopy
Fritzsche, Moritz Bernd Karl (2023-01-30)Die Eigenschaften von Gläsern hängen vor allem von deren chemischen Zusammensetzung ab und sind aufgrund der großen Zusammensetzungsvielfalt sehr variabel, was eine Vielzahl von Anwendungsmöglichkeiten eröffnet. <br ... -
Aqueous solubility of drug-like compounds
Du-Cuny, Lei (2006)New effective experimental techniques in medicinal chemistry and pharmacology have resulted in a vast increase in the number of pharmacologically interesting compounds. However, the possibility of producing drug candidates ... -
Arithmetic structures on noncommutative tori with real multiplication
Plazas, Jorge (2007)We study the homogeneous coordinate rings of real multiplication noncommutative tori as defined by A. Polishchuk. Our aim is to understand how these rings give rise to an arithmetic structure on the noncommutative torus. ... -
Arterial-Spin-Labeling-Sequenzentwicklung zur Optimierung der 3T- & 7T-Perfusionsbildgebung und zur Permeabilitätsmodellierung
Schidlowski, Martin (2022-04-04)<strong>Arterial spin labeling sequence development for optimization of 3T & 7T perfusion imaging and for permeability modeling</strong> <br />Pseudo-continuous arterial spin labeling (pCASL) is a magnetic resonance technique ... -
Articulated Human Pose Estimation in Unconstrained Images and Videos
Iqbal, Umar (2018-12-12)The understanding of the articulated human body pose is of great interest in many scenarios. While humans have an unmatched ability to effortlessly extract and interpret such information in any unconstrained environment, ... -
