Preparation and testing of organic dye molecules as single photon sources on a chip
Creators: name: Polisseni, Claudio
Publisher: name: Imperial College London
Year: 2017

description: The physical realisation of a photonic quantum computer requires a reliable, fast, ondemand source of single indistinguishable photons. A promising candidate for one of these sources is a single dye molecule in a solid state matrix placed within the evanescent field of a photonic waveguide. This thesis explores the possibility of coupling of single dibenzoterrylene (DBT) molecules in an anthracene matrix to a silicon nitride waveguide at room temperature. I first discuss the theory by which photons from a DBT molecule can be evanescently coupled to a ridge waveguide. I present a novel growth method to form DBT-doped anthracene crystals which is very promising for applications to photonic devices. I discuss the methodology and the theory of such growth. I describe the confocal microscope I developed and used to image and characterise the emission of the single DBT molecules embedded in these crystals. My measurements show that the molecules are extremely stable single quantum emitters with a well-de ned polarization relative to the crystal axes. Measurements of the saturation intensity at room temperature allow me to estimate that a single DBT molecule could deliver at least 1012 photons before bleaching. This method of growth was used to deposit DBT molecules on top of a silicon nitride ridge waveguide. The results of the coupling experiment are shown. These include confocal images, saturation and lifetime measurements. The coupling efficiency is calculated and compared to what was simulated. The challenges of such structures are then presented. To tackle these challenges I deposited the molecules on top of lithium niobate and in silicon nitride slots. I conclude with a proposal for constructing the best photonic structure which would guarantee an easy deposition of the molecules and high coupling efficiencies.
The Intrinsic Shapes of Stellar Systems

description: I compute the estimated distribution function f(q) for the apparent axis ratio q of various types of stellar systems, using a nonparametric kernel method. I then invert f(q) to find the distribution of intrinsic axis ratios, using two different hypotheses: first, that the stellar systems are all oblate, and second, that they are all prolate. The shapes of globular clusters in our own galaxy are consistent, at the 99% confidence level, with both the oblate and prolate hypothesis. The shapes of dwarf galaxies in the Virgo cluster are consistent, at the 99% confidence level, with the prolate hypothesis, but inconsistent with the oblate hypothesis. The shapes of star clusters in the Large Magellanic Cloud, of ordinary elliptical galaxies, of brightest cluster ellipticals, and of galaxy clusters are all inconsistent, at the 99% confidence level, with both the oblate and prolate hypotheses. The globular clusters in our galaxy are older than their half-mass relaxation time, and are most likely rotationally flattened oblate spheroids. The other stellar systems considered are generally younger than their half-mass relaxation time, and thus are triaxial bodies flattened by anisotropy of their velocity dispersion.

description: Diverse interlayer tunability of physical properties of two-dimensional layers mostly lies in the covalent-like quasi-bonding that is significant in electronic structures but rather weak for energetics. Such characteristics result in various stacking orders that are energetically comparable but may significantly differ in terms of electronic structures, e.g. magnetism. Inspired by several recent experiments showing interlayer anti-ferromagnetically coupled CrI3 bilayers, we carried out first-principles calculations for CrI3 bilayers. We found that the anti-ferromagnetic coupling results from a new stacking order with the C2/m space group symmetry, rather than the graphene-like one with R3 as previously believed. Moreover, we demonstrated that the intra- and inter-layer couplings in CrI3 bilayer are governed by two different mechanisms, namely ferromagnetic super-exchange and direct-exchange interactions, which are largely decoupled because of their significant difference in strength at the strong- and weak-interaction limits. This allows the much weaker interlayer magnetic coupling to be more feasibly tuned by stacking orders solely. Given the fact that interlayer magnetic properties can be altered by changing crystal structure with different stacking orders, our work opens a new paradigm for tuning interlayer magnetic properties with the freedom of stacking order in two dimensional layered materials.
Understanding the degeneracies in NO$ν$A data

description: The combined analysis of $ν_μ$ disappearance and $ν_e$ appearance data of NO$ν$A experiment leads to three nearly degenerate solutions. This degeneracy can be understood in terms of deviations in $ν_e$ appearance signal, caused by unknown effects, with respect to the signal expected for a reference set of oscillations parameters. We define the reference set to be vacuum oscillations in the limit of maximal $θ_{23}$ and no CP-violation. We then calculate the deviations induced in the $ν_e$ appearance signal event rate by three unknown effects: (a) matter effects, due to normal or inverted hierarchy (b) octant effects, due to $θ_{23}$ being in higher or lower octant and (c) CP-violation, whether $δ_{CP} \sim - π/2$ or $δ_{CP} \sim π/2$. We find that the deviation caused by each of these effects is the same for NO$ν$A. The observed number of $ν_e$ events in NO$ν$A is equivalent to the increase caused by one of the effects. Therefore, the observed number of $ν_e$ appearance events of NO$ν$A is the net result of the increase caused by two of the unknown effects and the decrease caused by the third. Thus we get the three degenerate solutions. We also find that further data by NO$ν$A can not distinguish between these degenerate solutions but addition of one year of neutrino run of DUNE can make a distinction between all three solutions. The distinction between the two NH solutions and the IH solution becomes possible because of the larger matter effect in DUNE. The distinction between the two NH solutions with different octants is a result of the synergy between the anti-neutrino data of NO$ν$A and the neutrino data of DUNE.

Seeing the people for the trees: Impacts of conservation on human well-being in Northern Cambodia
Creators: name: Beauchamp, Emilie
Publisher: name: Imperial College London
Year: 2016

description: Over recent decades, conservation projects, such as Protected Areas (PAs) and Payment for Environmental Services (PES), have increasingly incorporated poverty alleviation goals or targets towards improving human well-being in addition to biodiversity conservation outcomes. While methods to evaluate biodiversity are widely available, there is less guidance on how to measure the impacts of conservation interventions on human lives. Economic proxies have been popular, yet rarely reflect the multi-faceted incentives of resource users and their responses to conservation interventions. In this study, I use mixed methods to investigate the effects of conservation interventions on human well-being in Northern Cambodia, using three complementary approaches at different geographical scales. The Northern Plains landscape provides an ideal context for this exercise, because it includes two PAs and three PES initiatives, while also facing increasing development pressures in the form of large-scale agro-industrial development interventions: Economic Land Concessions (ELCs). I begin by exploring correlates of the spatial placement of ELCs, their outcomes in terms of deforestation rates, and the extent to which these development interventions trade off against conservation goals. The evidence indicates that ELCs not only fail to achieve their intended outcome but are also the main predictor of deforestation in the region, compromising environmental sustainability in the long-run. I then build on an existing longitudinal dataset from the Northern Plains to provide a medium-term evaluation of the impacts of PAs and PES on the socio-economic status of households in villages within PAs, compared with matched villages outside PAs. I demonstrate that external factors remain the main contributors to the socio-economic status of households across the landscape, with combined PAs and PES slightly reducing the rate of increase in household economic status and agricultural productivity, yet without impeding household development. The second half of this PhD offers a qualitative exploration of the conceptualisations of human well-being in the study area, to capture the multidimensionality and heterogeneity of well-being in the landscape. I find that individual well-being as well as village solidarity and trust are heavily linked with issues relating to land and resources, and their governance. From this study I developed locally relevant indicators pertaining to perceptions of salient land issues, which allow a more accurate assessment of the subjective dimension of human well-being across a landscape that features competing land uses from PAs and ELCs. The research findings highlight the complexity of attributing conservation impacts and capturing the direct and indirect consequences of conservation and development policies, and demonstrate how a more nuanced evaluation of conservation impacts on humans can guide future conservation interventions.

description: Weak degeneracy of a graph is a variation of degeneracy that has a close relationship to many graph coloring parameters. In this article, we prove that planar graphs with distance of $3$-cycles at least 2 and no cycles of lengths $5, 6, 7$ are weakly $2$-degenerate. Furthermore, such graphs can be vertex-partitioned into two subgraphs, one of which has no edges, and the other is a forest.

description: The influence of transversely oriented sinusoidal wall corrugation on an incompressible isothermal flow in the near-wall region, subjected to adverse pressure gradient conditions at a friction Reynolds number of $Re_τ = 2500$, is investigated using Large Eddy Simulation. This study is a continuation of the work of Kamiński et al. (2024) devoted to dynamics of the flow in the regions of crests and downhill/uphill waviness parts, and where the impact of the local and global pressure gradient were analysed. It focuses on the influence of the waviness parameters, such as amplitude ($A$) and number of waviness periods ($N_λ$) on the turbulent boundary layer separation. In terms of the effective slope, $ES\propto|{dA}/{dx}|$, where $x$ is the streamwise direction, the analyzed cases included the configurations with $ES$ ranging from $ES=0$ (flat wall) to $ES=0.2455$ ($A/λ=0.051$, where $λ$ is the length of a single waviness). Specifically, the primary objective was to identify a combination of $A$ and $N_λ$ that would result in the greatest increase in the wall-shear stress $τ_w$, relative to the flat plate configuration, aiming to achieve the maximum postponement of turbulent separation. It is shown that the waviness significantly affects the flow field by enhancing the turbulent kinetic energy that leads to increased $τ_w$. In particular, it is shown that the enhancement in TKE depends mainly on $ES$ and not on particular values of $A$ and $N_λ$. Namely, the cases which are significantly diversified by $A$ and $N_λ$ but are characterised by the same $ES$ exhibit almost identical TKE profiles. The highest increase in the wall-shear stress compared to the reference flat plate configuration was observed for the combination of $A$ and $N_λ$ corresponding to $ES=0.1473$.

Experimental and numerical investigation of soft impact loading on aircraft materials
Creators: name: Zhou, Jie
Publisher: name: Imperial College London
Year: 2017

description: Bird strike poses a great hazard to aircraft components, such as the engine and windshield, during flight. Thus, it is critical to understand the impact resistance of key aircraft components under bird strike. During this PhD study, Aluminium Alloy 2024-T3 and laminated glass interlayered with thermoplastic polyurethane (TPU), which are commonly used as the materials of the aircraft fuselage and windshield respectively, are selected as impact target materials. Both laboratory-based experiments and finite element simulations are performed using a light gas gun and ABAQUS/EXPLICIT respectively. A good agreement is achieved between the experimental work and numerical predictions for the impact response. Two bird substitute materials were selected: RTV rubber and ballistic gelatine, whose dynamic pressure profiles are similar to that of a real bird during a high speed impact. Mechanical properties of both materials were investigated by conducting compression tests at quasi-static (0.25, 2.5 and 25 min-1) and intermediate rate (2760 min-1 to 22500 min-1). As a result, the relationship between true stress and strain is obtained and constitutive equations are established using the hyperelastic models, i.e. the Ogden, Mooney-Rivlin and Neo-Hookean. The 3D Digital Image Correlation technique was employed in the gas gun test of the AA 2024-T3 and TPU interlayered laminated glass. Thus, the impact compliance of both targets from rubber and gelatine impacts are attained and found to be roughly equal to the same initial projectile momentum. An FE simulation was used to model the experimental process and was validated against the DIC results. Moreover, the Hugoniot pressure plays a predominant role in laminated glass fracture during the impact, with the rubber projectile leading to a larger damage than the gelatine projectile given the same momentum. This is because the shock wave speed in the rubber is larger than that in the gelatine projectile. A validated FE simulation is therefore presented, which can be used to simulate real bird impact on real aircraft structures in the future. Thus, this PhD work can be potentially implemented into industrial research programmes to aid design and optimisation.

description: A comprehensive census of the stellar content of the nearby OB associations is presented, based on Hipparcos positions, proper motions, and parallaxes. Moving groups are identified by combining de Bruijne's refurbished convergent point method with the `Spaghetti method' of Hoogerwerf & Aguilar. Monte Carlo simulations are used to estimate the expected number of interloper field stars. Astrometric members are listed for 12 young stellar groups, out to a distance of ~650 pc. These are the 3 subgroups Upper Scorpius, Upper Centaurus Lupus and Lower Centaurus Crux of Sco OB2, as well as Vel OB2, Tr 10, Col 121, Per OB2, alpha Persei (Per OB3), Cas-Tau, Lac OB1, Cep OB2, and a new group designated as Cep OB6. The selection procedure corrects the list of previously known astrometric and photometric B- and A-type members, and identifies many new members, including a significant number of F stars, as well as evolved stars, e.g., the Wolf-Rayet stars gamma^2 Vel (Vel OB2) and EZ CMa (Col 121), and the classical Cepheid delta Cep in Cep OB6. In the nearest associations the later-type members include T Tauri objects and other pre-main sequence stars. Astrometric evidence for moving groups in the fields of R CrA, CMa OB1, Mon OB1, Ori OB1, Cam OB1, Cep OB3, Cep OB4, Cyg OB4, Cyg OB7, and Sct OB2, is inconclusive, due to their large distance or unfavorable kinematics. The mean distances of the well-established groups are systematically smaller than previous estimates. The mean motions display a systematic pattern, which is discussed in relation to the Gould Belt. Six of the 12 detected moving groups do not appear in the classical list of nearby OB associations. The number of unbound young stellar groups in the Solar neighbourhood may be significantly larger than thought previously.

Finite-volume effects due to spatially non-local operators

description: Spatially non-local matrix elements are useful lattice-QCD observables in a variety of contexts, for example in determining hadron structure. To quote credible estimates of the systematic uncertainties in these calculations, one must understand, among other things, the size of the finite-volume effects when such matrix elements are extracted from numerical lattice calculations. In this work, we estimate finite-volume effects for matrix elements of non-local operators, composed of two currents displaced in a spatial direction by a distance $ξ$. We find that the finite-volume corrections depend on the details of the matrix element. If the external state is the lightest degree of freedom in the theory, e.g.~the pion in QCD, then the volume corrections scale as $ e^{-m_π(L- ξ)} $, where $m_π$ is the mass of the light state. For heavier external states the usual $e^{- m_πL}$ form is recovered, but with a polynomial prefactor of the form $L^m/|L - ξ|^n$ that can lead to enhanced volume effects. These observations are potentially relevant to a wide variety of observables being studied using lattice QCD, including parton distribution functions, double-beta-decay and Compton-scattering matrix elements, and long-range weak matrix elements.

Phytochrome-based fluorophores: sensitive tools for heme detection and in vivo imaging in bacterial pathogens
Creators: name: Mullineaux Sanders, Caroline Elizabeth
Publisher: name: Imperial College London
Year: 2016

description: The acquisition of iron is crucial for bacterial pathogenesis. In this thesis I describe the development and validation of a biosensor for heme in bacteria, an important host source of iron for human pathogens. I demonstrate that the co-expression of a phytochrome-based fluorophore (PBF), which utilises the heme-derived metabolite biliverdin IXα as a chromophore, with a heme oxygenase (HO) in Gram-negative bacteria results in heme-dependent near infra-red fluorescence. Using this PBF+HO reporter, I probe heme metabolism in the opportunistic human pathogen Pseudomonas aeruginosa and for the first time provide direct evidence linking the previously putative heme receptor HxuC to heme metabolism. Further, coupling of the heme biosensor to transposon mutagenesis and Fluorescence-Activated Cell Sorting was used to screen a P. aeruginosa transposon library leading to the identification of several putative novel components of heme metabolism. Finally, I demonstrate the potential of our fluorescent biosensor to be used to study heme metabolism and host-pathogen interactions in vivo using a live adult zebrafish model of infection. The PBF+HO heme biosensor allows the highthroughput, non-invasive study of bacterial heme metabolism in real-time and proves a useful tool for gaining further insight into iron-heme metabolism in bacterial pathogens.

description: This paper introduces a 3D shape generative model based on deep neural networks. A new image-like (i.e., tensor) data representation for genus-zero 3D shapes is devised. It is based on the observation that complicated shapes can be well represented by multiple parameterizations (charts), each focusing on a different part of the shape. The new tensor data representation is used as input to Generative Adversarial Networks for the task of 3D shape generation. The 3D shape tensor representation is based on a multi-chart structure that enjoys a shape covering property and scale-translation rigidity. Scale-translation rigidity facilitates high quality 3D shape learning and guarantees unique reconstruction. The multi-chart structure uses as input a dataset of 3D shapes (with arbitrary connectivity) and a sparse correspondence between them. The output of our algorithm is a generative model that learns the shape distribution and is able to generate novel shapes, interpolate shapes, and explore the generated shape space. The effectiveness of the method is demonstrated for the task of anatomic shape generation including human body and bone (teeth) shape generation.
Distributions of Peak Flux and Duration for Gamma-Ray Bursts

description: Many of the important conclusions about Gamma-Ray Bursts follow from the distributions of various quantities such as peak flux or duration. We show that for astrophysical transients such as bursts, multiple selection thresholds can lead to various forms of data truncation, which can strongly affect the distributions obtained from the data if not accounted for properly. Thus the data should be considered to form a multivariate distribution. We also caution that if the variables forming the multivariate distribution are not statistically independent of each other, further biases can result. A general method is described to properly account for these effects, and as a specific example we extract the distributions of flux and duration from the BATSE 3B Gamma-Ray Burst data. It is shown that properly accounting for the aforementioned biases tends to increase the slope of the $\log{N}$-$\log{S}$ relation at low values of $S$, and dramatically increases the number of short duration bursts.

description: Using two-dimensional numerical simulations of gravitational clustering, with initial power spectra of a power-law form with index n, we compare the properties of voids in real space to their properties in redshift space. Both the void probability function (VPF) and the underdense probability function (UPF) are enhanced in redshift space. The enhancement is greatest in the limit n=-2. The VPF and UPF treat voids statistically and assume that two-dimensional voids are circular; we present an algorithm which detects individual voids. Voids found by this algorithm are ellipses whose enclosed density of galaxies falls below a threshold density. When voids are identified using this algorithm, the mean void size and the maximum void size both increase in going from real space to redshift space. The increase is greatest in the limit n=-2. In redshift space, the principal axes of the largest voids in the n=2 and n=0 simulations show a statistically significant tendency (at the 95% confidence level) to be distributed anisotropically, relative to the line of sight from the origin to the void center.

description: We present fully nonparametric estimates of the frequency function of elliptical galaxy intrinsic shapes under the axisymmetric and triaxial hypotheses. If elliptical galaxies are assumed to be oblate or prolate, the frequency function of intrinsic shapes is negative for axis ratios near unity due to the lack of apparently round galaxies. Both axisymmetric hypotheses are found to be inconsistent at the 99 percent level with the data. Triaxial intrinsic shapes are fully consistent with the data; a number of possible triaxial frequency functions are presented, some of which exhibit strong bimodality. We also compute the ``maximum entropy'' distribution of intrinsic shapes under the triaxial hypothesis.

description: A topologized semilattice $X$ is complete if each non-empty chain $C\subset X$ has $\inf C\in\bar C$ and $\sup C\in\bar C$. It is proved that for any complete subsemilattice $X$ of a functionally Hausdorff semitopological semilattice $Y$ the partial order $P=\{(x,y)\in X\times X:xy=x\}$ of $X$ is closed in $Y\times Y$ and hence $X$ is closed in $Y$. This implies that for any continuous homomorphism $h:X\to Y$ from a compete topologized semilattice $X$ to a functionally Hausdorff semitopological semilattice $Y$ the image $h(X)$ is closed in $Y$. The functional Hausdorffness of $Y$ in these two results can be replaced by the weaker separation axiom $\vec T_{2δ}$, defined in this paper.

Highly Ionized High Velocity Clouds: Intergalactic Gas in the Local Group or Distant Gas in the Galactic Halo?

description: We have recently identified several high velocity (V < -100 km/s) clouds in the directions of Mrk 509 and PKS 2155-304 that have unusual ionization properties. The clouds exhibit strong C IV absorption with little or no detectable low ion (C II, Si II) absorption or H I 21cm emission. As the closest known analog to the outer diffuse halos of damped Ly-alpha absorbers and the low H I column density metal line absorption systems seen in the spectra of high redshift quasars, these "C IV-HVCs" present unique opportunities for relating the conditions within the Milky Way halo and nearby intergalactic gas to the properties of galactic halos at higher redshift. The C IV-HVCs have ionization properties consistent with photoionization by extragalactic background radiation, though some contribution by collisional ionization within a hot plasma cannot be ruled out. The clouds are probably low density [n(H) ~ 10^-4 cm^-3], large [greater than several kiloparsecs], and mostly ionized [n(HI)/n(H) ~ 10^-3] regions located well beyond the neutral gas layer of the Galaxy. The presence of weak H I-HVCs detected through 21cm emission near both sight lines indicates that the C IV-HVCs trace the extended, ionized, low density regions of the H I-HVCs. Several lines of evidence, including very low thermal pressures (P/k ~ 2 cm^-3 K), favor a location for the C IV-HVCs in the Local Group or very distant Galactic halo.

Bioactive glass nanoparticles for therapeutic applications
Creators: name: Greasley, Sarah Louise
Publisher: name: Imperial College London
Year: 2015

description: There is great therapeutic potential for bioactive glass nanoparticles, as they can be internalised within cells and achieve sustained intracellular delivery of active ions. Bioactive glass nanoparticles are also used in nano-composites. The Stӧber process is commonly used for synthesising spherical silica particles. This thesis reports a comprehensive study of how the process variables can be systematically altered to obtain monodispersed particles of specific sizes in the range 20 – 500 nm. Modification of the Stӧber process so that the particles can contain cations such as calcium, which can impart bioactivity, while maintaining monodispersity, is therefore highly desirable. Here, both zinc and calcium incorporation is achieved, with a homogenous distribution and without affecting the size, dispersity or morphology of the particles. However, careful characterisation shows that much of the cations were not incorporated and a washing step was essential, which suggests that previous reports are likely to have overestimated the amount of calcium incorporated. A maximum of 8.9 ± 1.1 mol % CaO and 22.7 ± 0.8 mol % ZnO was incorporated into the particles. Monodispersed mesoporous silica particles were also synthesised in this thesis, containing up to 18.5 ± 2.7 mol % Ca and 21.5 ± 1.3 mol % Zn. The differences in incorporation between the two cations were attributed to the different roles that they play within the silicate network. Whilst calcium acts purely as a network modifier, zinc can also act as a network former. These differences are seen to affect % cation incorporation, surface area, network connectivity and subsequent degradation. Nanoparticles of 80 - 100 nm were readily internalised by cells, where they were located both within vesicles and also as individual particles within the cytoplasm (having escaped from the endosomal pathway). SiO2-ZnO mesoporous particles were also seen to subsequently degrade rapidly inside cells, demonstrating preferential toxicity to cancer cells due to pH sensitive intracellular release of toxic Zn2+ ions. SiO2-CaO particles were successfully functionalised and show great potential for incorporation into nano-composites for bone regeneration.
Structure-preserving finite element methods for fluids
Creators: name: Natale, Andrea
Publisher: name: Imperial College London
Year: 2017

description: Many fluid models share a common geometric structure which is usually ignored by the standard algorithms used in computer simulations. As a consequence, numerical solutions may often exhibit unphysical behaviour and fail to reproduce certain features of the governing equations, such as conservation laws or symmetries. In this thesis we use the framework of finite element exterior calculus to derive discretisations for fluid systems that preserve as much as possible of their geometric structure. The main part of this work is devoted to the discretisation of the incompressible Euler equations. We construct a finite-dimensional approximation of these equations by mimicking their variational derivation and preserving the particle relabelling symmetry. As a consequence, we obtain a finite element scheme that conserves energy and possesses a discrete version of Kelvin’s circulation theorem. The variational derivation also introduces a new form of energy-conserving upwind stabilisation in the discrete advection term. We find that this reproduces the energy backscatter which characterises two-dimensional turbulence; we study this behaviour numerically, by comparing our discretisation with other types of upwind schemes. In addition, we address a number of issues related to structure preservation in finite element discretisations, primarily motivated by applications in geophysical fluid dynamics. Specifically, we study the approximation properties of tensor product finite element spaces of differential forms and we show how to generalise these to manifolds. Moreover, we use similar spaces to characterise the convergence to zonal flows of time-averaged discrete approximations of incompressible flows on a rotating sphere.

description: We describe a robust Bayesian statistical method for determining Lyman alpha forest cloud sizes in spherical and in thin disk geometries, using absorption in adjacent sightlines toward closely separated QSO pairs and groups, apply this method to the available data, and discuss implications of our results for models of Ly alpha clouds. Under the assumption of a population of uniform- size and unclustered clouds, the data from Q1343+2640A/B give a 99% confidence lower and upper bounds 61 0.4 A threshold on all linelists, we find a trend of larger inferred cloud radius with larger proper separation of QSO pairs, significant at the 3.4 sigma level. This indicates that the idealization of unclustered, uniform-sized clouds does not accurately describe the Ly alpha cloud population.
