Topological analysis of microtubules during cell division
… to characterize the single and multi-chain topological complexity of such systems. We create computational methods for analyzing the topology of microtubules obtained through large electron tomography data. Our results show that the geometry/topology and entanglement of microtubules changes …

Topological analysis of the grain boundary space
… boundary space not only facilitates statistical analysis of grain boundaries, but can also help describe the structure-property relationships of these interfaces.

Topological Analysis Using Morse Theory and Auditory Display
Finally, we demonstrate the use of wave traversal for creating an auditory display of a simplicial complex. This has application particularly when the complex is large or higher-dimensional, but audio has been shown to reinforce visual display in all cases. The auditory display is intended to …

Characterisation and topological analysis of novel metal-organic frameworks
The investigation of complexes in the solid state has developed exponentially over the past few decades in terms of both crystal engineering and supramolecular chemistry. The preparation of new metal-organic frameworks and coordination polymers has been of particular interest due to the large …

Topological analysis of singularity loci for serial and parallel manipulators
Singularities of robot manipulators have been intensely studied in the last decades by researchers of many fields. Serial singularities produce some local loss of dexterity of the manipulator, therefore it might be desirable to search for singularityfree trajectories in the jointspace. On the other …

Spatial and Temporal Topological Analysis of Landscape Structure using Graph Theory
… a landscape. Traditional approaches to spatial analysis mainly entail the use of spatial statistics and classical spatial data structures to analyse the composition of a landscape. However, such analyses are unable to capture the essence of landscape configuration because spatial relationships …

The conserved dedA family of E. coli membrane proteins: genetic and topological analysis
… 500 mM NaCl but not 400 mM sucrose. Microscopic analysis of Lud135 demonstrates a dramatic defect at a late stage of cell division when cells are grown under permissive conditions. Lud135 is non-motile and overproduces outer membrane vesicles that contain FliC. Preliminary results from the …

Molecular dynamics simulation and topological analysis of the network structure of actinide-bearing materials
… on actinide waste storage shows the utility of topological methods for quantifying the intermediate-range structure of amorphous systems. In many cases, the intermediate-range structure correlates with larger-scale properties, such as density and viscosity. I then identify three molten salt …

Using Persistent Homology for Topological Analysis of Protein Interaction Network of Candida Antarctica Lipase B Molecular Dynamic Simulation Model
… (homology groups) in different states. Employing topological analysis, we compare the active form of CalB at high temperatures to its inactive states to account for possible topological contributions to the protein functionality. By discovering a prominent 1-dimensional hole in the active form of …

A comparison of crystalline and molten structures of zirconolite (CaZrTi₂O₇), a potential plutonium wasteform medium, by molecular dynamics simulation and topological analysis
… structures were compared. Local primitive-ring topological clusters were determined for individual atoms, and averages of ring counts were calculated for atom types within each form of zirconolite. The ideal crystalline structure and the best experimental structure, deduced by Rossell from …

Molecular Engineering of Dipolar and Octupolar Non-Linear Optical Materials for Next-Generation Telecommunications
… materials forms an integral part of this thesis. Topological analysis is applied to these electronic structures, using the quantum theory of atoms in molecules (QTAIM), from which the structural and chemical origins of their NLO properties are assessed. Complementary theoretical methods were also …

Higher-Order Interactions in Social Systems
… explores a different paradigm of social network analysis, namely, using "higher-order" network models such as hypergraphs and simplicial complexes which can explicitly encode co-present contexts between three or more individuals. The first two projects describe how higher-order interactions can …

On the topological properties of the vibrations of solids
This thesis presents the study of the topological properties in the atomic vibrations in solids. The state-of-the-art quantum mechanical simulation techniques are presented first to accurately describe the band structures of electrons and vibrational spectra of nuclei for topological analysis. Two …

Local-global geographies of tacit knowledge production in London and New York's advertising and law professional service firms
… sensitive approach to examine learning. Such an analysis is then applied in order to understand the geographies of knowledge production in global advertising and law firms. Three themes are addressed. First, why is tacit knowledge important in the work of these firms? Second, what are the key …

Crystal engineering of dynamic metal organic frameworks for applications in chromic sensing and capturing of small molecules
… performed by single crystal X-ray diffraction. Topological analysis was performed on the networks formed by the compounds to have a better understanding of the network connectivity. Bulk material was characterised by thermal methods such as thermogravimetric analysis (TGA), differential scanning …

Topology and geometry-based methods for quantifying the complexity of protein structures
New topological and geometrical methods in knot theory provide a way to rigorously measure the entanglement of open curves in 3-space for the first time. These methods enable the topological analysis of physical systems of filaments, such as those formed by proteins. In this dissertation we employ …
