description: Generalized Wess-Zumino models which admit topologically non-trivial BPS saturated configurations along one compact, spatial dimension are investigated in various dimensions of space-time. We show that, in a representative model and for sufficiently large circumference, there are BPS configurations along the compact dimension containing an arbitrary number of equidistant, well-separated domain walls. We analyze the spectrum of the bosonic and fermionic light and massless modes that are localized on these walls. The masses of the light modes are exponentially suppressed by the ratio of the distance between the walls and their width. States that are initially localized on one wall oscillate in time between all the walls. In (2+1) dimensions the ``chirality'' of localized, massless fermions is determined. In the (1+1)-dimensional case we show how the mass of certain classically BPS saturated solitons is lifted above the BPS bound by instanton tunneling.

description: We present the catalog of ~31500 extragalactic HI line sources detected by the completed ALFALFA survey out to z < 0.06 including both high signal-to-noise ratio (> 6.5) detections and ones of lower quality which coincide in both position and recessional velocity with galaxies of known redshift. We review the observing technique, data reduction pipeline, and catalog construction process, focusing on details of particular relevance to understanding the catalog's compiled parameters. We further describe and make available the digital HI line spectra associated with the catalogued sources. In addition to the extragalactic HI line detections, we report nine confirmed OH megamasers and ten OH megamaser candidates at 0.16 < z < 0.22 whose OH line signals are redshifted into the ALFALFA frequency band. Because of complexities in data collection and processing associated with the use of a feed-horn array on a complex single-dish antenna in the terrestrial radio frequency interference environment, we also present a list of suggestions and caveats for consideration by users of the ALFALFA extragalactic catalog for future scientific investigations.

description: In this work, the self energies of $π^0$ and $π^{\pm}$ up to one loop order have been calculated in the limit of weak external magnetic field. The effective masses are explicitly dependent on the magnetic field which are modified significantly for the pseudoscalar coupling due to weak field approximation of the external field. On the other hand, for the pseudovector coupling, there is a modest increment in the effective masses of the pions. These theoretical developments are relevant for the study of the phenomenological aspect of mesons in the context of neutron stars as well as heavy ion collisions.

title: Characterisation of Fluid-Flow Systems for Irish Lead-Zinc Deposits
Creators: name: Lewis, Helen
Publisher: name: University of Glasgow
Year: 1995
Subjects: subject: Geology, Petrology

description: The lead-zinc sulphide deposits of central Ireland are hosted primarily in Lower Carboniferous strata of the Midland Basin. The ores are thought to be approximately contemporaneous with their sedimentary hosts, but the mode of their formation is a subject of dispute. The mineralisation is variously regarded as having either a predominantly sedimentary-exhalative, or a predominantly MVT-type of genesis. The ores are hydrothermal, so the interpretation of mineral genesis is strongly linked to the interpretation of the fluid-flow system that generated the deposits. This thesis investigates the structural setting of the deposits, particularly in relation to faults, on both the regional and more local scales, and the nature of the fluid-flow systems that could have provided the mineralised fluids. The structural setting is established by reconstructing the geometry of the Midland Basin region, and restoring it to several stages in its Early Carboniferous development. The reconstruction and restorations identify a style of basin development dominated by the movement (mostly subsidence) of fault-bounded blocks of basement, with superjacent sedimentary rocks. The restorations reveal a spatial relationship between ore deposits and fault-block corners. This spatial relationship is proposed to have significance for exploration. The flow systems which could have been active in the Midland Basin and its surrounds (including the Munster Basin) are investigated using both mass balance, and numerical simulations of heat- and fluid-flow. The mass balance study shows that most of the suggested flow systems could have produced adequate metals, but tens to several thousand fluid pore-volumes are required to deliver these metals to the sites of deposition, thus eliminating compaction as a driving mechanism, and severely limiting the applicability of some of the other putative causes of fluid flow. When the results of the mass-balance and the numerical models are combined, they show that: regional flow systems could not have developed in central Ireland during the Carboniferous; gravity-driven flow is cold, shallow and only very local; but local convective systems that penetrate deep into the fractured basement not only develop in this setting, but are very stable. Convective circulation of hydrothermal fluids is the most likely cause of the Irish lead-zinc mineralisation.
The Equilibrium-Tide Model for Tidal Friction

description: We derive from first principles equations governing (a) the quadrupole tensor of a star distorted by both rotation and the presence of a companion in a possibly eccentric orbit, (b) a functional form for the dissipative force of tidal friction, based on the concept that the rate of energy loss from a time-dependent tide should be a positive-definite function of the rate of change of the quadrupole tensor as seen in the frame which rotates with the star, and (c) the equations governing the rates of change of the magnitude and direction of the stellar rotation, and the orbital period and eccentricity, based on the concept of the Laplace-Runge-Lenz vector. Our analysis leads relatively simply to a closed set of equations, valid for arbitrary inclination of the stellar spin to the orbit. The results are equivalent to classical results based on the rather less clear principle that the tidal bulge lags behind the line of centres by some time determined by the rate of dissipation; our analysis gives the effective lag time as a function of the dissipation rate and the quadrupole moment. We discuss briefly some possible applications of the formulation.

p53, a Novel Inhibitor of Apoptosis
Creators: name: Chee, Lai Yuen
Publisher: name: Imperial College London
Year: 2011

description: p53 is a transcription factor known to induce apoptosis via transactivating the expression of pro-apoptotic proteins and by directly activating the mitochondria apoptotic pathway. p53 is also found to be mutated in 50% of human cancers with some of these tumours overexpressing both wild type (WT) and mutant p53. Overexpression of the p53 protein has been implicated with the more aggressive nature of these tumour cells, suggesting a possible gain-of-function of such mutants. In this study, the involvement of p53 in apoptosis via the caspase pathway was investigated. WT-p53 and three mutant p53 with mutations at the 1) N-terminus (D42Y), 2) central domain (R175H) and 3) C-terminus (R337H) were selected. The data collected demonstrated that p53 was able to inhibit the cleavage of caspases early in the apoptotic pathway. In vitro assays showed that addition of recombinant WT and the mutant p53 inhibited the cleavage of both caspase-9 and caspase-3 and subsequently PARP, while overexpression of p53 in mammalian cells yielded the same inhibition profile in vivo. Conversely, removal of p53 via siRNA and immunodepletetion showed accelerated caspase-9 activity and cleavage. Immunoprecipitation experiments and recombinant assay systems suggest that the inhibition by p53 is targeted at the active cleaved caspase-9. In addition, the presence of p53 (WT or mutant) in p53-null cells were able to confer a higher survival rate. These data therefore demonstrate that p53 may have an additional anti-apoptotic role via the inhibition of caspase-9, which is often masked by its pro-apoptotic functions. This anti-apoptotic role could manifest itself in a cancer background overexpressing mutant p53 which has lost its transcriptional activity and hence its ability to induce apoptosis via the induction of pro-apoptotic genes such as PUMA and NOXA. This newly discovered role of p53 could potentially explain the aggressive nature of cancers which overexpress p53.

description: It is known that the partition function and correlators of the two-dimensional topological field theory $G_K(N)/ G_K(N)$ on the Riemann surface $Σ_{g,s}$ is given by Verlinde numbers, dim($V_{g,s,K}$) and that the large $K$ limit of dim($V_{g,s,K}$) gives Vol(${\cal M}_s$), the volume of the moduli space of flat connections of gauge group $G(N)$ on $Σ_{g,s}$, up to a power of $K$. Given this relationship, we complete the computation of Vol(${\cal M}_s$) using only algebraic results from conformal field theory. The group-level duality of $G(N)_K$ is used to show that if $G(N)$ is a classical group, then $\displaystyle \lim_{N\rightarrow \infty} G_K(N) / G_K(N)$ is a BF theory with gauge group $G(K)$. Therefore this limit computes Vol(${\cal M}^\prime_s$), the volume of the moduli space of flat connections of gauge group $G(K)$.
IMMUNOLOGICAL CHARACTERISTICS OF LATENT TUBERCULOSIS INFECTION

description: Tuberculosis (TB) continues to be one of the top 10 causes of death worldwide, caused by Mycobacterium tuberculosis. According to WHO, in 2021, 1.4 million HIV-negative and 187,000 HIV-positive TB deaths were reported worldwide. Latent tuberculosis infection (LTBI) is an immune response against M. tuberculosis without clinical manifestations or radiological evidence of active TB. Current diagnostic methods are insufficient to differentiate between healthy and latently infected populations. Here, we used a machine learning approach to analyze publicly available proteomic data from saliva and serum in Ethiopia's healthy, latent TB (LTBI) and active TB (ATBI) people. Our analysis discovered a profile of six proteins, Mast Cell Expressed Membrane Protein-1, Hemopexin, Lamin A/C, Small Proline Rich Protein 2F, Immunoglobulin Kappa Variable 4-1, and Voltage Dependent Anion Channel 2 that can precisely differentiate between the healthy and latently infected populations. This data suggests that a combination of six host proteins can serve as accurate biomarkers to diagnose latent infection. This is important for populations living in high-risk areas as it may help in the surveillance and prevention of severe disease.

description: With the advent of Deep Learning (DL) techniques, especially Generative Adversarial Networks (GANs), data augmentation and generation are quickly evolving domains that have raised much interest recently. However, the DL techniques are data demanding and since, medical data is not easily accessible, they suffer from data insufficiency. To deal with this limitation, different data augmentation techniques are used. Here, we propose a novel unsupervised data-driven approach for data augmentation that can generate 2D Computed Tomography (CT) images using a simple GAN. The generated CT images have good global and local features of a real CT image and can be used to augment the training datasets for effective learning. In this proof-of-concept study, we show that our proposed solution using GANs is able to capture some of the global and local CT variabilities. Our network is able to generate visually realistic CT images and we aim to further enhance its output by scaling it to a higher resolution and potentially from 2D to 3D.

description: Istat calculates the value of electricity from renewable sources. The variable is defined as the percentage of electricity consumption covered by renewable sources out of total gross internal consumption. The indicator is obtained as the ratio between the actual gross electricity production from RES (not normalised) and the Gross Domestic Consumption of electricity (equal to the gross production of electricity gross of production from pumping contributions plus the balance of exchanges with the abroad or between regions). The data refers to the period between 2004 and 2021 in the Italian regions.
Quantitative imaging with mechanical waves
Creators: name: Huthwaite, Peter Edward
Publisher: name: Imperial College London
Year: 2012

description: Quantitative imaging complements structural imaging by providing quantitative estimations of subsurface material properties as opposed to the sizes, shapes and positions of scatterers available from structural methods. The ability to reconstruct material properties from a series of wave measurements is extremely valuable in a range of applications as it potentially allows diagnostic technology with superior sensitivity and selectivity. Breast cancer, for example, is stiffer and hence of higher sound velocity than the surrounding tissue, so reconstructing velocity from ultrasonic measurements could allow cancer detection. Using this concept, breast ultrasound tomography has the potential to significantly improve the cost, safety and reliability of breast cancer screening and diagnosis over mammography, the gold-standard. Key to unlocking this potential is the availability of an accurate, fast, robust and high-resolution algorithm to reconstruct wave velocity. This thesis introduces HARBUT, the Hybrid Algorithm for Robust Breast Ultrasound Tomography, a new imaging approach combining the complementary strengths of low resolution bent-ray tomography and high resolution diffraction tomography. HARBUT's theoretical foundation is explained and applied to simulated and experimental, in-vivo, breast ultrasound tomography data, confirming that it generates a step change in image quality over existing techniques, revealing lesions that would not be visible on a mammogram. This thesis also shows how, by combining data from many slices, the out-of-plane resolution can be significantly improved compared to treating each slice independently. HARBUT is applied to alternative problems including guided wave tomography, which aims to quantify the remaining wall thickness of a potentially corroded, inaccessible plate-like structure. Thickness estimates within 1mm for a 10mm nominal thickness plate were demonstrated for both simulated and experimental data. The thesis finally investigates HARBUT's performance with limited view configurations, and introduces VISCIT, the Virtual Image Space Component Iterative Technique, which accounts for the missing data, significantly improving the reconstructed image.

Fermionic Zero Modes and Spontaneous Symmetry Breaking on the Light Front

description: Spontaneous symmetry breaking is studied within a simple version of the light-front sigma model with fermions. Its vacuum structure is derived by an implementation of global symmetries in terms of unitary operators in a finite volume with periodic fermi field. Due to the dynamical fermion zero mode, the vector and axial U(1) charges do not annihilate the light-front vacuum. The latter is transformed into a continuous set of degenerate vacuum states, leading to to the spontaneous breakdown of the axial symmetry. The existence of associated massless Nambu-Goldstone boson is demonstrated.

A reduction of the equations is performed in the case when the Dirac field is {\em static} and a further reduction is performed in the case of {\em spherical symmetry}. These static spherically symmetric equations are examined in some detail and a numerical solution presented. Some surprising results emerge: * Spherical symmetry necessitates the existence of a magnetic monopole. * There exists a uniquely defined solution, determined only by the demand that the solution be analytic at infinity. * The equations describe highly compact objects with an inner onion-like shell structure.

Investigation of the mechanisms underlying the regulation of macrophage activation and glomerular inflammation by JunD
Creators: name: Hull, Richard Peter
Publisher: name: Imperial College London
Year: 2011

description: Macrophages are the predominant immune effector cell found in one of the most severe causes of renal failure in humans, crescentic glomerulonephritis (Crgn). The Wistar Kyoto (WLY) rat is uniquely susceptible among rat strains to Crgn and susceptibility genes have previously been mapped to seven quantitative trait loci (Crgn1-7). The AP-1 transcription factor JunD is markedly overexpressed in WKY macrophages and was identified as a major determinant of macrophage activation associated with Crgn susceptibility at Crgn2. The work presented in this thesis aimed to investigate mechanisms underlying the regulation of macrophage activation and glomerular inflammation by JunD in the NTN-susceptible WKY rat strain and in patients with Crgn. Genomic-based approaches, including microarray analysis of bone marrow-derived macrophage transcriptomes, RNA interference and cistrome analysis using ChIP-Seq, along with histological techniques and genotyping studies, were used to identify key genes and pathways underlying JunD-mediated activation of macrophages. Transcriptome analyses showed that the Crgn2 locus regulates expression of over 800 genes in WKY macrophage responses to lipopolysaccharide (LPS). Acute changes in Jund expression by RNA interference also modulated gene expression in WKY macrophages, including effector genes for the macrophage LPS response. Cistrome analysis revealed that genetically determined differences in Jund expression alter its genome binding pattern and the increased numbers of JunD-bound genes in WKY macrophages were functionally linked with signalling pathways and cell activation. Integration of the data identified 47 genes, that were associated with JunD binding peaks and whose expression was both regulated by Crgn2 and altered by siRNA knockdown of Jund, as the key candidates through which JunD determines macrophage activation. Overall, this work provides the basis for understanding genes and pathways through which JunD regulates macrophage activation and has identified novel gene targets for modulation of macrophage phenotypes in WKY rat and human macrophages.
Superextendons with a modified measure

description: For superstrings, the consequences of replacing the measure of integration $\sqrt{-γ}d^2 x$ in the Polyakov's action by $Φd^2 x$ where $Φ$ is a density built out of degrees of freedom independent of the metric $γ_{ab}$ defined in the string are studied. As in Siegel reformulation of the Green Schwarz formalism the Wess-Zumino term is the square of supersymmetric currents. As opposed to the Siegel case, the compensating fields needed for this do not enter into the action just as in a total derivative. They instead play a crucial role to make up a consistent dynamics. The string tension appears as an integration constant of the equations of motion. The generalization to higher dimensional extended objects is also studied using in this case the Bergshoeff and Sezgin formalism with the associated additional fields, which again are dynamically relevant unlike the standard formulation. Also unlike the standard formulation, there is no need of a cosmological term on the world brane.

description: Context: Protostellar jets in high-mass young stellar objects (HMYSOs) play a key role in the understanding of star formation and provide us with an excellent tool to study fundamental properties of HMYSOs. Aims: We aim at studying the physical and kinematic properties of the near-IR (NIR) jet of IRAS\,13481-6124 from au to parsec scales. Methods: Our study includes NIR data from the Very Large Telescope instruments SINFONI, CRIRES, and ISAAC. Information about the source and its immediate environment is retrieved with SINFONI. The technique of spectro-astrometry is performed with CRIRES to study the jet on au scales. The parsec-scale jet and its kinematic and dynamic properties are investigated using ISAAC. Results: The SINFONI spectra in the $H$ and $K$ band are rich in emission lines that are mainly associated with ejection and accretion processes. Spectro-astrometry is applied to the Br$γ$ line, and for the first time, to the Br$α$ line, revealing their jet origin with milliarcsecond-scale photocentre displacements ($11-15$\,au). This allows us to constrain the kinematics of the au-scale jet and to derive its position angle ($\sim216^{\circ}$). ISAAC spectroscopy reveals H$_2$ emission along the parsec-scale jet, which allows us to infer kinematic and dynamic properties of the NIR parsec-scale jet. The mass-loss rate inferred for the NIR jet is $\dot{M}_\mathrm{ejec}\sim10^{-4}\mathrm{\,M_\odot\,yr^{-1}}$ and the thrust is $\dot{P}\sim10^{-2}\mathrm{\,M_\odot\,yr^{-1}\,km\,s^{-1}}$ , which is roughly constant for the formation history of the young star. A tentative estimate of the ionisation fraction is derived for the massive jet by comparing the radio and NIR mass-loss rates. An ionisation fraction $\lesssim8\%$ is obtained, which means that the bulk of the ejecta is traced by the NIR jet and that the radio jet only delineates a small portion of it.

description: This study was to evaluate the biological activity of the extract of Botryosphaeria fabicerciana isolated from leaves of Morus nigra. The volatile compounds from the crude extract were analysed by GC-MS which demonstrate that mellein and β-orcinaldehyde were are the major compounds. The best minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the extract was observed against Gram-positive bacteria, with a MIC of 15.6 μg/mL towards B. cereus and MIC of 62.5 μg/mL towards S. aureus and B. subtilis. MBC values of 31.25 μg/mL, 62.5 μg/mL, and 250 μg/mL were observed towards B. cereus, B. subtilis, and S. aureus, respectively. The cytotoxicity analyses showed CC50 of 115 μg/mL. The crude extract showed antioxidant activity by the DPPH, ABTS, and FRAP assays. Therefore, the extract of the endophytic fungus presented biotechnological potential as an antibacterial and antioxidant agent.
Highly Localised Surface Plasmon Polaritons in Active Metallo-organic Multilayer Structures
Creators: name: Yoon, Hong
Publisher: name: Imperial College London
Year: 2012

description: Amplification of surface plasmon polaritons in plasmonic systems have been of great interest for realizing active nanophotonic devices. In this thesis, we present a study about optical gain of SPPs supported in planar metallo-organic multilayer structures based on the Kretchmann geometry. First, we present the effect of varying the geometry on behaviours of surface plasmon propagation, which appear as the change of angular reflectivity. A theoretical approach explains the characteristics well. A kind of conjugated polymer material is introduced to the structures for obtaining gain. A film of this material with nanometer thickness is attached close to a metallic layer, being optically excited to supply energy. For understanding the interaction between surface plasmon polaritons and the active films, we experimentally investigate energy transfer channels from the active material to surface plasmons with an aid of a theoretical analysis. This result provides a strong evidence of being capable of exciting surface plasmon polaritons via dipole excitation. We also report an experimental demonstration of optical gain properties in conventional waveguide structures where the active material acts as propagating channel by measuring amplified spontaneous emission phenomena, providing information of achievable optical gain. Based on the strong evidences of both the active and passive properties, we demonstrate plasmonic gain in the structure incorporating the polymer film for the first time. For this, a double lock-in amplifier system is introduced. Plasmonic modal gain is explained with a support of theoretical estimates. The achieved modal gain is 9 cm-1. This work suggests the design principle for active nano plasmonic devices.

description: The moiré superstructure of graphene grown on metals can drive the assembly of molecular architectures, as iron-phthalocyanine (FePc) molecules, allowing for the production of artificial molecular configurations. A detailed analysis of the Gr/Co interaction upon intercalation (including a modelling of the resulting moiré pattern) is performed here by density functional theory, which provides an accurate description of the template as a function of the corrugation parameters. The theoretical results are a preliminary step to describe the interaction process of the FePc molecules adsorption on the Gr/Co system. Core level photoemission and absorption spectroscopies have been employed to control the preferential adsorption regions of the FePc on the graphene moiré superstructure and the interaction of the central Fe ion with the underlying Co. Our results show that upon molecular adsorption the distance of C atoms from the Co template mainly drives the strength of the molecules-substrate interaction, thereby allowing for locally different electronic properties within the corrugated interface.

On the kinematic signature of a central Galactic bar in observed star samples

description: A quasi self-consistent model for a barred structure in the central regions of our Galaxy is used to calculate the signature of such a triaxial structure on the kinematical properties of star samples. We argue that, due to the presence of a velocity dispersion, such effects are much harder to detect in the stellar component than in the gas. It might be almost impossible to detect stellar kinematical evidence for a bar using only l-v diagrams, if there is no a priori knowledge of the potential. Therefore, we propose some test parameters that can easily be applied to observed star samples, and that also incorporate distances or proper motions. We discus the diagnostic power of these tests as a function of the sample size and the bar strength. We conclude that about 1000 stars would be necessary to diagnose triaxiality with some statistical confidence.

description: In this paper the relationship between the problem of constructing the ground state energy for the quantum quartic oscillator and the problem of computing mean eigenvalue of large positively definite random hermitean matrices is established. This relationship enables one to present several more or less closed expressions for the oscillator energy. One of such expressions is given in the form of simple recurrence relations derived by means of the method of orthogonal polynomials which is one of the basic tools in the theory of random matrices.

Control of Aluminium Anodization to Regulate the Optical Properties of Porous Aluminium Oxide Membranes
Creators: name: Orsi, Alice
Publisher: name: Imperial College London
Year: 2013

description: Porous alumina anodized (PAA) membranes are widely used as templates for electrodeposition of conductive materials or directly as photonic material [1-3] due to the regular distribution of pores when anodized under defined temperature, electrolyte and voltage. This thesis investigated PAA nucleation and development under constant voltage in order to develop a periodic anodizing procedure to control pore diameter and interpore distance along the pore main axis. The periodic change in the geometrical parameters modifies the optical properties of the membranes and visible light interacts with the porous membrane when the periodicity of the structure is of the same order as the light wavelength. Two porous structures with reflectance peaks in the visible range were realized and their optical properties were studied. Branched membranes presented alternated layers of branched pore and main pore layers of controllable thicknesses. The reflectance spectra was modelled as a Bragg stack whose thicknesses and refractive indices of the alternating layers were obtained from ellipsometrical and SEM measurements of PAA membranes. The second structure was defined as necked membrane, as it presented periodic enlargements and restrictions of pore diameter along the pore main axis without branching. Reflectance spectra showed a single peak in the visible range whose position could be controlled by the anodizing temperature. Reflectance spectra showed by branched and necked samples were considered promising with regards to applications as interleaved reflectors in reflective displays. The presence of selective reflective layers interleaved in a stack display reduces light losses due to undesired absorbance of colour layers and more freedom in display design. [4] 1.

description: We generalise the fusion procedure for the $A_{\n-1}^{(1)}$ open spin chain ($\n>2$) and we show that the transfer matrix satisfies a crossing property. We use these results to solve the $A_{\n-1}^{(1)}$ open spin chain with $U_{q} (SU(\n))$ symmetry by means of the analytical Bethe ansatz method. Our results coincide with the known ones obtained by means of the nested Bethe ansatz.
