description: The Eisenbud-Wigner-Smith (EWS) time delay of photoemission depends on the phase term of the matrix element describing the transition. Because of an interference process between partial channels, the photoelectrons acquire a spin polarization which is also related to the phase term. The analytical model for estimating the time delay by measuring the spin polarization is reviewed in this manuscript. In particular, the distinction between scattering EWS and interfering EWS time delay will be introduced, providing an insight in the chronoscopy of photoemission. The method is applied to the recent experimental data for Cu(111) presented in M. Fanciulli et al., PRL 118, 067402 (2017), allowing to give better upper and lower bounds and estimates for the EWS time delays.

Seismic wavefield modelling and application in viscoelastic media
Creators: name: Ning, Chao
Publisher: name: Imperial College London
Year: 2016

description: Accurate seismic exploration demands sophisticated seismic techniques that can be applied to any complex geological structures. The key of most recent seismic processing techniques is wave propagation modelling. For accurate simulation of the seismic wavefield, the characteristics of the real Earth media should be appropriately considered, such as attenuation effects and anisotropy. This dissertation aims to address the attenuation problems in seismic wavefield modelling in attenuative media and its related applications. My work presented in this dissertation includes 1. A viscoelastic wave equation for isotropic media is proposed. The attenuation operator applied in the wave equation consists of separate terms, which are related to velocity dispersion and energy absorption effects respectively. It is derived that the two effects are completely decoupled. 2. A numerical scheme based on low-rank approximation is presented for wave simulation in heterogeneous attenuative media. This method can achieve very high accuracy while the computational cost is greatly reduced compared with conventional method. 3. In order to take account of the anisotropic attenuation, a generalized viscoelastic wave equation is presented. The velocity dispersion and energy absorption effects are also decoupled in the encapsulated attenuation operators. Based on this, the seismic wave propagation in arbitrary anisotropic media with anisotropic attenuation can be accurately simulated. 4. Q-compensated reverse-time migration (RTM) is investigated. It is shown that the velocity dispersion and energy absorption effects should be taken care of separately. Attributed to the completed decoupled attenuation effects in the derived viscoelastic wave equation, the \Q-compensation operator is derived. As a result, the dispersion correction and energy compensation is successfully separated and can be implemented simultaneously. Based on this, different \Q-compensation schemes are analysed and compared.

description: In this white paper we introduce the IMAGINE Consortium and its scientific background, goals and structure. Our purpose is to coordinate and facilitate the efforts of a diverse group of researchers in the broad areas of the interstellar medium, Galactic magnetic fields and cosmic rays, and our goal is to develop more comprehensive insights into the structures and roles of interstellar magnetic fields and their interactions with cosmic rays. To achieve a higher level of self-consistency, depth and rigour can only be achieved by the coordinated efforts of experts in diverse areas of astrophysics involved in observational, theoretical and numerical work. We present our view of the present status of this topic, identify its key unsolved problems and suggest a strategy that will underpin our work. The backbone of the consortium is the Interstellar MAGnetic field INference Engine, a publicly available Bayesian platform that employs robust statistical methods to explore the multi-dimensional likelihood space using any number of modular inputs. It provides an interpretation and modelling framework that has the power and flexibility to include a variety of observational, theoretical and numerical lines of evidence into a self-consistent and comprehensive picture of the thermal and non-thermal interstellar media. An important innovation is that a consistent understanding of the phenomena that are directly or indirectly influenced by the Galactic magnetic field, such as the deflection of ultra-high energy cosmic rays or extragalactic backgrounds, is made an integral part of the modelling. The IMAGINE Consortium, which is informal by nature and open to new participants, hereby presents a methodological framework for the modelling and understanding of Galactic magnetic fields that is available to all communities whose research relies on a state-of-the-art solution to this problem.

The amplitude, scale and dependence on galaxy colours of the observed overdensity are consistent with its being a result of the magnification bias caused by the weak gravitational lensing of large scale structures at redshift $z \approx 0.2-0.4$ and are hardly explained by other causes, as obscuration by dust.

description: In languages like C, buffer overflows are widespread. A common mitigation technique is to use tools that detect them during execution and abort the program to prevent the leakage of data or the diversion of control flow. However, for server applications, it would be desirable to prevent such errors while maintaining availability of the system. To this end, we present an approach to handle buffer overflows without aborting the program. This approach involves implementing a continuation logic in library functions based on an introspection function that allows querying the size of a buffer. We demonstrate that introspection can be implemented in popular bug-finding and bug-mitigation tools such as LLVM's AddressSanitizer, SoftBound, and Intel-MPX-based bounds checking. We evaluated our approach in a case study of real-world bugs and show that for tools that explicitly track bounds data, introspection results in a low performance overhead.

Statistical models for spatio-temporal extrema and dependencies
Creators: name: Noven, Ragnhild Cassel
Publisher: name: Imperial College London
Year: 2016

description: This thesis develops statistical models for capturing the dependence characteristics and distributional structures of spatio-temporal data. In the first part we propose a parsimonious stochastic process model for characterising rainfall time series. It is shown that the model is sufficiently flexible to capture important features of the rainfall process at different locations and time scales. We also study an application to the pricing of rainfall derivatives that introduces the market price of risk via the Esscher transform, and calculate futures prices based on empirical rainfall data. In the second part we consider statistical models based on the class of trawl processes, which are stationary, infinitely divisible stochastic processes. We discuss properties of this class and introduce a novel representation of trawl processes in terms of independent random variables. The trawl process class is used to construct a new model for characterising temporal dependence in exceedances above a threshold, which has the proper limiting distribution from extreme value theory. We illustrate the model by applying it to time series of rainfall and pollution measurements, and demonstrate its ability to capture the dependence structure of extreme value data. The third part of the thesis introduces a framework for hierarchical models based on trawl processes, which includes the extreme value model as a special case. We develop a targeted MCMC algorithm for this class of models, which exploits the trawl process representation from the second part. We also introduce two specific models in this framework, and fit the second model to a time series of wind production. In the final part we consider a wider class of processes for spatio-temporal modelling, which contains the specific models considered previously. We discuss the construction of models with specific covariance functions, and introduce a discrete approximation for these processes.
Distances from Surface Brightness Fluctuations

description: The practice of measuring galaxy distances from their spatial fluctuations in surface brightness is now a decade old. While several past articles have included some review material, this is the first intended as a comprehensive review of the surface brightness fluctuation (SBF) method. The method is conceptually quite simple, the basic idea being that nearby (but unresolved) star clusters and galaxies appear "bumpy", while more distant ones appear smooth. This is quantified via a measurement of the amplitude of the Poisson fluctuations in the number of unresolved stars encompassed by a CCD pixel (usually in an image of an elliptical galaxy). Here, we describe the technical details and difficulties involved in making SBF measurements, discuss theoretical and empirical calibrations of the method, and review the numerous applications of the method from the ground and space, in the optical and near-infrared. We include discussions of stellar population effects and the "universality" of the SBF standard candle. A final section considers the future of the method.

description: For practical applications, the long time behaviour of the error of numerical solutions to time-dependent partial differential equations is very important. Here, we investigate this topic in the context of hyperbolic conservation laws and flux reconstruction schemes, focusing on the schemes in the discontinuous Galerkin spectral element framework. For linear problems with constant coefficients, it is well-known in the literature that the choice of the numerical flux (e.g. central or upwind) and the selection of the polynomial basis (e.g. Gauß-Legendre or Gauß-Lobatto-Legendre) affects both the growth rate and the asymptotic value of the error. Here, we extend these investigations of the long time error to variable coefficients using both Gauß-Lobatto-Legendre and Gauß-Legendre nodes as well as several numerical fluxes. We derive conditions guaranteeing that the errors are still bounded in time. Furthermore, we analyse the error behaviour under these conditions and demonstrate in several numerical tests similarities to the case of constant coefficients. However, if these conditions are violated, the error shows a completely different behaviour. Indeed, by applying central numerical fluxes, the error increases without upper bound while upwind numerical fluxes can still result in uniformly bounded numerical errors. An explanation for this phenomenon is given, confirming our analytical investigations.

Investigating the Type IV pili of Clostridium difficile and Clostridium sordellii
Creators: name: Couchman, Edward
Publisher: name: Imperial College London
Year: 2016

description: Type IV pili (T4P) are the only type of bacterial pili known to be produced by both Gram-negative and Gram-positive organisms. Though the main pilus shaft consists primarily of only one protein (the major pilin), T4P are unusual in their complexity, requiring multiple (10 or more) different protein components for assembly. Like most types of pili, T4P often function as virulence factors. In particular, T4P frequently operate as adhesins, enabling bacteria on which they are present to stick to each other (to form a biofilm or suchlike) or to adhere directly to host cells. Many T4P systems are able to retract, in which case the T4P may mediate flagella-independent motility. Most research into T4P has historically been performed on Gram-negative organisms, with T4P-encoding genes only being identified in Gram-positive organisms more recently. In particular, all sequenced species of the genus Clostridium are known to encode T4P, but only minimal investigation of these systems has been performed to date. In this study, the T4P of Clostridium difficile were investigated. C. difficile is an important pathogen, being the leading cause of antibiotic-associated diarrhoea in the developed world and thus a considerable burden on Western healthcare systems. By investigating the T4P of this species it was hoped to further elucidate its mechanisms of pathogenicity. Data is presented demonstrating the control of T4P expression by cyclic-di-GMP, and identifying which genes are essential for T4P production in C. difficile. Additionally, a genomic analysis of the related pathogen Clostridium sordellii was performed, using the first high quality genome sequence produced for this species. Genes encoding T4P were identified, analysed and investigated. Furthermore, plasmids carrying the genes encoding the species’ key virulence factors (Lethal Toxin, TcsL, and in some cases haemorrhagic toxin, TcsH) were identified. These plasmids appear to be unstable, a fact with significant implications for diagnosis of C. sordellii disease.

description: In Papers I and II, we have used a free-energy minimization approach that stems from the Landau-Ginzburg theory of phase transitions to describe in simple and clear physical terms the secular and dynamical instabilities as well as the bifurcations along equilibrium sequences of rotating, self-gravitating fluid systems. Here we investigate the secular and dynamical 3rd-harmonic instabilities that appear first on the Jacobi sequence of incompressible zero- vorticity ellipsoids. Poincare found a bifurcation point on the Jacobi sequence where a 3rd-harmonic mode becomes neutral. A sequence of pear-shaped equilibria branches off at this point but stands at higher energies. Therefore, the Jacobi ellipsoids remain secularly and dynamically stable. Cartan found that dynamical 3rd-harmonic instability also sets in at the Jacobi-pear bifurcation. We find that Cartan's instability leads to differentially rotating objects and not to uniformly rotating pear-shaped equilibria. We demonstrate that the pear-shaped sequence exists at higher energies and at higher rotation relative to the Jacobi sequence. The Jacobi ellipsoid undergoes fission on a secular time scale and a short-period binary is produced. The classical fission hypothesis of binary-star formation of Poincare and Darwin is thus feasible.

Markovian rough paths
Creators: name: Ogrodnik, Marcel Bogdan
Publisher: name: Imperial College London
Year: 2016

description: The accumulated local p-variation functional, originally presented by Cass et al. (2013), arises naturally in the theory of rough paths in estimates both for solutions to rough differential equations (RDEs), and for the higher-order terms of the signature (or Lyons lift). In stochastic examples, it has been observed that the tails of the accumulated local p-variation functional typically decay much faster than the tails of classical p-variation. This observation has been decisive, e.g. for problems involving Malliavin calculus for Gaussian rough paths as illustrated in the work by Cass et al. (2015). All of the examples treated so far have been in this Gaussian setting, that contains a great deal of additional structure. In this paper we work in the context of Markov processes on a locally compact Polish space E, which are associated to a class of Dirichlet forms. In this general framework, we first prove a better-than-exponential tail estimate for the accumulated local p-variation functional derived from the intrinsic metric of this Dirichlet form. By then specialising to a class of Dirichlet forms on the step-⌊p⌋ free nilpotent group, which are subelliptic in the sense of Fefferman-Phong, we derive a better than exponential tail estimate for a class of Markovian rough paths. This class includes, but also goes beyond, the examples studied by Friz and Victoir (2008). We comment on the significance of these estimates to recent results, including the results of Hao (2014) and Chevyrev and Lyons (2015).

description: We investigate the electronic transport properties of semiconducting ($m$,$n$) carbon nanotubes (CNTs) on the mesoscopic length scale with arbitrarily distributed realistic defects. The study is done by performing quantum transport calculations based on recursive Green's function techniques and an underlying density-functional-based tight-binding model for the description of the electronic structure. Zigzag CNTs as well as chiral CNTs of different diameter are considered. Different defects are exemplarily represented by monovacancies and divacancies. We show the energy-dependent transmission and the temperature-dependent conductance as a function of the number of defects. In the limit of many defetcs, the transport is described by strong localization. Corresponding localization lengths are calculated (energy dependent and temperature dependent) and systematically compared for a large number of CNTs. It is shown, that a distinction by $(m-n)\,\mathrm{mod}\,3$ has to be drawn in order to classify CNTs with different bandgaps. Besides this, the localization length for a given defect probability per unit cell depends linearly on the CNT diameter, but not on the CNT chirality. Finally, elastic mean free paths in the diffusive regime are computed for the limit of few defects, yielding qualitatively same statements.

description: This paper presents a high-resolution radio continuum (843 MHz) survey of the Vela supernova remnant. The contrast between the structures in the central pulsar-powered nebula of the remnant and the synchrotron radiation shell allows the remnant to be identified morphologically as a member of the composite class. The data are the first of a composite remnant at spatial scales comparable with those available for the Cygnus Loop and the Crab Nebula, and make possible a comparison of radio, optical and soft X-ray emission from the resolved shell filaments. The survey, made with the Molonglo Observatory Synthesis Telescope, covers an area of 50 square degrees at a resolution of 43'' x 60'', while imaging structures on scales up to 30'.

Novel applications of luminescence for solar energy
Creators: name: Videira, Jose Joao Henriques
Publisher: name: Imperial College London
Year: 2016

description: Luminescent solar concentrators (LSCs) provide indirect light concentration by absorbing both direct and indirect incident light, and have applications in building-integrated photovoltaics (BIPV). Fibre LSCs were found to have a linear relationship between photon concentration and fibre lengths in scales suitable for LSC modules. Using raytrace modelling, cylindrical LSC arrays were found to exhibit light trapping properties at certain angles of incidence, which can pave the way for more efficient BIPV applications. Novel optics for a double-illuminated water splitting reactor were introduced, for the objective of solar hydrogen for energy storage and sustainable transport fuels. A reflective cone embedded in a waveguide reflects incident concentrated light into the waveguide. Raytrace modelling and practical high concentration measurements demonstrate the viability of the optical system as well as necessity for a perfectly smooth reflective cone. It was also shown that replaced the reflective cone with a quantum well solar cell (QWSC) in order to harness the photoluminescence (PL) is not a viable concept with current QWSC structures. Another form of sustainable transport fuels is to use biofuels produced by algae. Algae have evolved to absorb excess amounts of energy, even when it is detrimental to their own growth and survival. This causes inefficiencies when growing algae in raceway ponds. The luminescent solar diffuser (LSD) is an optical funnel, optimisable by use of a genetic algorithm, that can be retrofitted into an algae raceway pond in order to better distribute incident light into the pond depths. This was calculated to increase algae growth rates in the pond, thereby increasing the yield of an algae farm.

Vision-based retargeting for endoscopic navigation
Creators: name: Ye, Menglong
Publisher: name: Imperial College London
Year: 2016

description: Endoscopy is a standard procedure for visualising the human gastrointestinal tract. With the advances in biophotonics, imaging techniques such as narrow band imaging, confocal laser endomicroscopy, and optical coherence tomography can be combined with normal endoscopy for assisting the early diagnosis of diseases, such as cancer. In the past decade, optical biopsy has emerged to be an effective tool for tissue analysis, allowing in vivo and in situ assessment of pathological sites with real-time feature-enhanced microscopic images. However, the non-invasive nature of optical biopsy leads to an intra-examination retargeting problem, which is associated with the difficulty of re-localising a biopsied site consistently throughout the whole examination. In addition to intra-examination retargeting, retargeting of a pathological site is even more challenging across examinations, due to tissue deformation and changing tissue morphologies and appearances. The purpose of this thesis is to address both the intra- and inter-examination retargeting problems associated with optical biopsy. We propose a novel vision-based framework for intra-examination retargeting. The proposed framework is based on combining visual tracking and detection with online learning of the appearance of the biopsied site. Furthermore, a novel cascaded detection approach based on random forests and structured support vector machines is developed to achieve efficient retargeting. To cater for reliable inter-examination retargeting, the solution provided in this thesis is achieved by solving an image retrieval problem, for which an online scene association approach is proposed to summarise an endoscopic video collected in the first examination into distinctive scenes. A hashing-based approach is then used to learn the intrinsic representations of these scenes, such that retargeting can be achieved in subsequent examinations by retrieving the relevant images using the learnt representations. For performance evaluation of the proposed frameworks, extensive phantom, ex vivo and in vivo experiments have been conducted, with results demonstrating the robustness and potential clinical values of the methods proposed.
Mass Distributions of Clusters Using Gravitational Magnification

description: Lensing in the context of rich clusters is normally quantified from small image distortions, yielding a relative mass distribution in the limit of weak lensing. Here we show the magnification effect of lensing can also be mapped over a cluster, resulting in absolute mass determinations for the weak limit. Furthermore, given both magnification and distortion measurements, the mass distribution may be constrained in the strong regime. Methods for obtaining the magnification using spectroscopic and/or photometric information are discussed, for object detection within a fixed isophote or to a given flux limit. A map of the magnification around A1689 is constructed from the observed depletion of background red galaxy counts.

description: We study the information-geometric properties of the Deser-Sarioglu-Tekin black hole, which is a higher derivative gravity solution with contributions from a non-polynomial term of the Weyl tensor to the Einstein-Hilbert Lagrangian. Our investigation is focused on deriving the relevant information metrics and their scalar curvatures on the space of equilibrium states. The analysis is conducted within the framework of thermodynamic information geometry and shows highly non-trivial statistical behavior. Furthermore, the quasilocal formalism, developed by Brown and York, was successfully implemented in order to derive the mass of the Deser-Sarioglu-Tekin black hole.

Limits on the Boron Isotopic Ratio in HD 76932

description: Data in the 2090 A B region of HD 76932 have been obtained at high S/N using the HST GHRS echelle at a resolution of 90,000. This wavelength region has been previously identified as a likely candidate for observing the B11/B10 isotopic splitting. The observations do not match a calculated line profile extremely well at any abundance for any isotopic ratio. If the B abundance previously determined from observations at 2500 A is assumed, the calculated line profile is too weak, indicating a possible blending line. Assuming that the absorption at 2090 A is entirely due to boron, the best-fit total B abundance is higher than but consistent with that obtained at 2500 A, and the best-fit isotopic ratio (B11/B10) is in the range ~10:1 to ~4:1. If the absorption is not entirely due to B and there is an unknown blend, the best-fit isotopic ratio may be closer to 1:1. Future observations of a similar metal-poor star known to have unusually low B should allow us to distinguish between these two possibilities. The constraints that can be placed on the isotopic ratio based on comparisons with similar observations of HD 102870 and HD 61421 (Procyon) are also discussed.

Structural studies on histamine receptors
Creators: name: Geng, Tian
Publisher: name: Imperial College London
Year: 2015

description: The work presented in this thesis concerns a sub-family of the biologically important family of G-protein coupled receptors (GPCRs) known as histamine receptors. They are recognized as important drug targets for many disorders in mankind, such as allergic rhinitis and Alzheimer’s disease. This thesis has its roots in the first structure of histamine receptor H1, determined in complex with a first generation antihistamine (doxepin) in 2011. Here, extensive biological, computational and structural investigations have been carried out for H1 in complex with two second-generation antihistamines (cetirizine and fexofenadine). Crystal structures of H1-cetirizine (3.1 Å) and H1-fexofenadine (3.4 Å) show the binding modes of second-generation antihistamines correspond well with the previous docking studies. The so-called “anion binding site” on H1 is responsible for the high specificity of the ligands. Some regions on the receptor were difficult to define in the crystal structures. These regions were characterized by radioligand binding assays, together with molecular dynamic simulations (carried out by our collaborators from Oxford University) suggested that, second generation ligands have a significantly large impact on receptor dynamics. While H1 mediates many immune-related disorders, the histamine receptor H3 is a drug target to many mental disorders. In addition to the H1 work presented here, it is also reported the initial work done on the histamine receptor H3. With extensive screenings on various H3 constructs (from human and turkey organisms) and expression systems, it was observed that the best construct was from turkey. An optimal expression protocol in insect cells was obtained. This has established a secure starting point for future structural studies on H3.
Trends and forecasts in cause-specific mortality

Publisher: name: Imperial College London
Year: 2015

description: Mortality forecasting models are typically limited in that they pertain only to national death rates, predict only all-cause mortality, or do not capture and utilize the correlation among diseases. I have developed a novel Bayesian hierarchical model that jointly forecasts cause- specific death rates for geographic subunits. I examined the model’s effectiveness by applying it to United States vital statistics data from 1982 to 2011 that I prepared using a new cause of death reassignment algorithm. I found that the model not only generated coherent forecasts for mutually exclusive causes of death, but it also exhibited lower out-of-sample error than alternative commonly-used models for forecasting mortality. I then used the model to produce forecasts of US cause-specific mortality through 2025 and analysed the resulting trends. I found that total death rates in the US were likely to continue their decline, but at a slower rate of improvement than has been observed for the past several decades. While death rates due to major causes of death like ischaemic heart disease, stroke, and lung cancer were projected to continue trending downward, increases in causes such as unintentional injuries and mental and neurological conditions offset many of these gains. These findings suggest that the US health system will need to adapt to a changing cause composition of disease burden as its population ages in the coming decade. Forecasting research should continue to consider how to best incorporate and balance the many dimensions of mortality when producing projections.

description: When a quantum phase transition is crossed in finite time, critical slowing down leads to the breakdown of adiabatic dynamics and the formation of topological defects. The average density of defects scales with the quench rate following a universal power-law predicted by the Kibble-Zurek mechanism. We analyze the full counting statistics of kinks and report the exact kink number distribution in the transverse-field quantum Ising model. Kink statistics is described by the Poisson binomial distribution with all cumulants exhibiting a universal power-law scaling with the quench rate. In the absence of finite-size effects, the distribution approaches a normal one, a feature that is expected to apply broadly in systems described by the Kibble-Zurek mechanism.
