Abstract:

For many years, the theoretical and experimental study of eddy current non-destructive evaluation (NDE) has been conducted separately, as most models were not suited to practical industrial applications. The aim of this work is to bridge this gap by investigating the relationship between magnetic fields and defects using both modelling and experimental study and to link these results to quantitative NDE. In this work, 3D FEM numerical simulations are used to predict the response of an eddy current probe being scanned over the area of a defect and understand the underlying change in magnetic fi

Abstract:

DNA methylation is increasingly recognised as a significant epigenetic event that may initiate and drive the process of neoplasia in humans. In the colon, DNA methylation of key genes is common in a subset of colorectal cancers. The extent to which DNA methylation at various genes contributes to initiation of colorectal neoplasms is less clear. This study sought to clarify the biological and clinicopathological significance of methylation of various genes in the development of sporadic and familial colorectal neoplasia.

A new APT specimen fabrication process was developed with the ability to select a specific defect for APT analysis.

General ideas in the conformal bootstrap program are covered. Both numerical and analytical approaches to the bootstrap equation are reviewed to show how it can be manipulated in different ways. Further analytical approaches are studied for theories with defects.

Anomalous dimensions for bulk- and defect-local fields as well as one of the OPE coefficients are found to the first loop order. Implications of inserting this defect and constraints that arises

Quick mass production of homogeneous thin film material is required in paper, plastic, fabric, and thin film industries.

Abstract:

There are several reasons to be interested in conformal field theories in two dimensions. Apart from arising in various physical applications, ranging from statistical mechanics to string theory, conformal field theory is a class of quantum field theories that is interesting on its own. First of all there is a large amount of symmetries. In addition, many of the interesting theories satisfy a finiteness condition, that together with the symmetries allows for a fully non-perturbative treatment, and even for a complete solution in a mathematically rigorous manner.

BACKGROUND:Cancers often arise within an area of cells (e.g. an epithelial patch) that is predisposed to the development of cancer, i.e. a "field of cancerization" or "field defect."

If a field defect were deficient in DNA repair, DNA damages would tend to escape repair and give rise to carcinogenic mutations.PURPOSE:To determine whether reduced expression of DNA repair proteins Pms2, Ercc1 and Xpf (pairing partner of Ercc1) are early steps in progression to colon cancer.RESULTS:Tissue biopsies were ta

Abstract:

This thesis outlines methods for generating new integrable defects in affine Toda field theory. These methods are grounded in the hypothesis that defects have a particle-like classification with as many species of fundamental defect existing in a particular affine Toda theory as there are species of soliton. The methods employed are: 1. Defect fusing rules, linking different species of defect in the same theory. Defect fusing rules are used in this thesis to find transmission matrices for a new, species 2, defect in a^(1)_3. 2. Folding, linking defects in simply laced theories to defects in no

This thesis expands previous work on defects appearing in classical integrable field theories, with a generalised form for momentum conserving defects being found. It is shown that the defect equations can always be augmented to give a Bäcklund transformation for the bulk theory, and new momentum conserving defects are found for the Br and Dr ATFTs. Momentum conservation is shown to be a necessary condition if the system is to have an infinite number of conserved quantities for all defects in ATFTs. The D4 defect in particular is investigated, with the system shown to have a zero curvature rep

Abstract:

The infinite-dimensional symmetry algebra of a conformal field theory (CFT), the Virasoro algebra, is generated by the holomorphic and anti-holomorphic part of the stress tensor. Besides such 'chiral symmetries' the CFT also has an integrable symmetry, that is, infinite families of commuting conserved charges. In this thesis a step towards combining these two symmetries into a single formalism is taken, by identifying integrable stuctures of a CFT through studying the representation category of the underlying chiral algebra. Then by introducing defects in the system, conserved charges can be c

Abstract:

In this thesis, we examine the construction and characteristics of generalised reflection matrices, within the a_1^(1), a_2^(1) and a_2^(2) integrable affine Toda field theories. In doing so, we generalise the existing finite-dimensional reflection matrices because our construction involves the dressing of an integrable boundary with a defect. Within this framework, an integrable defect's ability to store an unlimited amount of topological charge is exploited, therefore all generalised solutions are intrinsically infinite-dimensional and exhibit interesting features.

Abstract:

Dans les alliages multiphasés, la cohérence des interfaces entre des phases en désaccord paramétrique génère des champs élastiques internes à longue distance et généralement anisotropes. L'interaction de ces champs affecte fortement la cinétique des transformations de phase diffusives, et influence la forme et l'arrangement spatial des précipités. Dans la microstructure des superalliages monocristallins à base de nickel, obtenue par précipitation de la phase γ’ ordonnée L12 dans la matrice CFC γ, l'élasticité conduit à la formation d'alignements quasi-périodiques des précipités γ’ cuboïdaux.

Abstract:

The integration of defence companies in Europe and the U.S. has in the defence market’s environment for a long time received considerable interest. Companies see business opportunities and attractive technology on the other side of the Atlantic Ocean. Governments advocate in a public discourse that transatlantic defence industry integration is highly desirable and that it would benefit all concerned. This supportive discourse is compared to the action; the corporate integration that has occurred. The aim of the thesis is to understand and explain the level and nature of the transatlantic defen

Abstract:

This thesis addresses the behaviour of artificial magnetic square spin ice patterns in response to applied magnetic fields and thermal activation. Two main points of focus are the access of well-defined statistical states and the properties of fractionalised “monopole” charge defects. Experimental investigations are conducted using magnetic force microscopy of athermal remanent states. Magnetic reversal of a square ice subject to magnetic fields applied slightly off a diagonal symmetry axis is found to mediate via incremental sublattice-independent processes. Dipolar correlations manifest as c

Abstract:

Electrically detected magnetic resonance (EDMR) is a sensitive spectroscopic technique, which can be used to readout few to single electron spins in semiconductor and carbon nanodevices for applications in solid state quantum information processing (QIP). Since only electrically active defects contribute to the EDMR signal, this technique can be used further to investigate defects and impurities in photovoltaic devices, in which they limit the sunlight-to-energy conversion efficiency significantly. Here, I employ X-band EDMR for semiconductor defect analysis and identify the most important rec
