description: It is well established that the parasites of the genus Leishmania exhibit complex surface interactions with the sandfly vector midgut epithelium, but no prior study has considered the details of their hydrodynamics. Here, the boundary behaviours of motile Leishmania mexicana promastigotes are explored in a computational study using the boundary element method, with a model flagellar beating pattern that has been identified from digital videomicroscopy. In particular a simple flagellar kinematics is observed and quantified using image processing and mode identification techniques, suggesting a simple mechanical driver for the Leishmania beat. Phase plane analysis and long-time simulation of a range of Leishmania swimming scenarios demonstrate an absence of stable boundary motility for an idealised model promastigote near passive or repulsive surfaces, with behaviours ranging from boundary capture to deflection into the bulk. Indeed, the inclusion of a repulsive surface force results in the deflection of all surface-bound promastigotes, suggesting that the documented surface detachment of infective metacyclic promastigotes may be the result of morphological adaptation and simple hydrodynamics. Further, simulation elucidates a remarkable morphology-dependent hydrodynamic mechanism of boundary approach, hypothesised to be the cause of the well-established phenomenon of tip-first epithelial attachment of Leishmania promastigotes to the sandfly vector midgut.

description: The demonstration of repeated gamma-ray bursts from an individual source would severely constrain burst source models. Recent reports (Quashnock and Lamb 1993; Wang and Lingenfelter 1993) of evidence for repetition in the first BATSE burst catalog have generated renewed interest in this issue. Here, we analyze the angular distribution of 585 bursts of the second BATSE catalog (Meegan et al. 1994). We search for evidence of burst recurrence using the nearest and farthest neighbor statistic and the two-point angular correlation function. We find the data to be consistent with the hypothesis that burst sources do not repeat; however, a repeater fraction of up to about 20% of the observed bursts cannot be excluded.

Diagnosis and application of laser wakefield accelerators
Creators: name: Cole, Jason Mark
Publisher: name: Imperial College London
Year: 2015

description: This thesis is concerned with experimental diagnostic methods of the laser-plasma interaction in laser wakefield accelerators, and how high energy photon beams from such accelerators may be exploited in a potential application. Raman scattered light from the 20 TW Astra laser pulse was found to have shorter wavelength than expected given the interferometrically-measured plasma density, due to the relativistic motion of plasma electrons. Simulations indicated that the scattering helps to shape the pulse, removing laser energy not trapped in the wake. The signature of Raman scatter from the 200 TW Astra-Gemini pulse was instead the generation of extended plasma filaments, the direction of which indicated weaker relativistic effects. Altering the focal spot position or quality generated more filaments and reduced electron beam charge, linking Raman scattering, pulse focussing, and accelerator performance. When a low intensity (10¹⁰ W/cm²) probe pulse crossed a high intensity (10¹⁹ W/cm²) drive pulse of equal frequency, the probe was observed to be amplified in intensity by up to 10⁵ over a distance of tens of microns. No frequency shift of the probe was observed, and the effect required the polarisations of the pulses to be parallel. In simulations the pulses created a ponderomotive grating, trapping electrons which were able to scatter the drive into the probe in the superradiant regime of Raman amplification. Laser wakefield-driven x-ray beams were used to perform a microtomographic scan of a human femoral trabecular bone sample. Under optimal conditions x-ray beams containing 1.3 ± 0.5 × 10⁹ photons were produced on 97% of laser shots, with critical energy 33 ± 12 keV and source size of 2-3 μm. Image resolution was 36 ± 7 μm and after 180 image acquisitions the 3D resolution of the tomogram was up to 50 μm. The average photon flux between 10 and 100 keV was 5.9 ± 2.4 × 10⁵ ph/s/mrad² which is comparable to microfocus sources capable of few-micron source sizes.

Asset allocation and portfolio optimization with small transaction costs
Creators: name: Liu, Cong
Publisher: name: Imperial College London
Year: 2016

description: This thesis is devoted to the asset allocation and portfolio optimization with small transaction costs. Three topics are studied. The first and second topics are on asset allocation problems with purely proportional transaction cost and strictly positive transaction cost, respectively. The fundamental objective is to keep the asset portfolio close to a target portfolio and in the meantime to reduce the trading cost in doing so. For each problem, we derive the quasi-variational inequality and prove a verification theorem giving sufficient conditions for a QVI solution to be the value function. The optimal strategy is a singular control in the first topic and an impulse control in the second. Furthermore, we provide a matrix exponential representation of the QVI solution for both problems and perform asymptotic analysis to characterize the optimal no transaction region when transaction costs are sufficiently small. Additionally, for both topics, we apply the asymptotic results for the boundary points and derive an expansion for the QVI solution, the optimality of which can be shown via verification theorem (up to leading orders). The third topic is on portfolio optimization with proportional transaction cost. We construct an efficient frontier problem (EFP) of maximizing expected terminal utility and minimizing terminal CVAR. We first solve the frictionless case by duality approach and nonsmooth analysis. For three representative utility functions, we obtain numerically the optimal trading strategy, optimal expected terminal utility and optimal CVAR. Our analysis of how these three quantities change with respect to different CVAR constraints provides flexibility for an investor to balance return and risk according to her own preference. We then include transaction cost to the EFP, which is equivalent to including transaction cost to a non-smooth utility maximization problem. Asymptotic analysis gives expansions for no transaction boundaries which are then applied to EFPs with different utility functions. This topic ends by numerical analysis on impact of introducing CVAR constraint and/or transaction cost for classical utility maximization problem.

Molecular analyses of malignant pleural mesothelioma
Creators: name: Lo, Shir Kiong (Karl)
Publisher: name: Imperial College London
Year: 2016

description: Malignant pleural mesothelioma (MPM) is an aggressive cancer that is strongly associated with asbestos exposure. Majority of patients with MPM present with advanced disease and the treatment paradigm mainly involves palliative chemotherapy and best supportive care. The current chemotherapy options are limited and ineffective hence there is an urgent need to improve patient outcomes. This requires better understanding of the genetic alterations driving MPM to improve diagnostic, prognostic and therapeutic strategies. This research aims to gain further insights in the pathogenesis of MPM by exploring the tumour transcriptional and mutational profiles. We compared gene expression profiles of 25 MPM tumours and 5 non-malignant pleura. This revealed differentially expressed genes involved in cell migration, invasion, cell cycle and the immune system that contribute to the malignant phenotype of MPM. We then constructed MPM-associated co-expression networks using weighted gene correlation network analysis to identify clusters of highly correlated genes. These identified three distinct molecular subtypes of MPM associated with genes involved in WNT and TGF-ß signalling pathways. Our results also revealed genes involved in cell cycle control especially the mitotic phase correlated significantly with poor prognosis. Through exome analysis of seven paired tumour/blood and 29 tumour samples, we identified frequent mutations in BAP1 and NF2. Additionally, the mutational profile of MPM is enriched with genes encoding FAK, MAPK and WNT signalling pathways. We also found mutations in several novel genes involved in chromatin remodelling other than BAP1 and SETD2 that may contribute to dysregulation of gene expression in MPM. In conclusion, MPM is a complex disease with heterogeneous molecular aberrations. By combining findings from both transcriptome and exome analyses, we identified alterations in genes involved in common signalling pathways such as FAK, WNT and MAPK. These may have important roles in driving MPM carcinogenesis with therapeutic implications and require further explorations.
User modelling for adaptive training in high performance driving
Creators: name: Georgiou, Theodosis
Publisher: name: Imperial College London

description: User model creation is a fundamental component for the development of intelligent personalised systems. This thesis proposes an adaptive user modelling framework that uses a combination of unobtrusive task-related and physiological data with the aim of identifying strengths and weaknesses in user performance in the defined task. The research is focused on utilising the framework to provide personalised content adaptation in car racing games. Our system adopts concepts from the Trace Theory (TT) framework, and uses machine learning techniques to extract specific features from the user and the game. These metrics are then transformed and evaluated into higher level abstractions such as experience, exploration and physiological attention by utilising the educational theoretical frameworks of Flow and Zone Theory. The end result is to provide new game paths utilising the user’s model. We demonstrate that this procedural generation of user-tailored content drives the self-motivating behaviour of players to immerse and engage themselves in the game’s virtual world. Collection of data and feedback from multiple users (52) allowed us to associate the model’s outcomes to the user responses, as well as device multiple trial scenarios to verify their training and engagement. We have also evaluated the algorithms for the generation of new tracks for their suitability on the skill’s profile of 41 of our subjects and race track diversity among the evolved paths. We have also designed a method for predicting the states of the user-controlled system by combining information from both sources – vehicle and user – via Gaussian Processes (GPs). In the context of high speed car racing we showed that the forthcoming position and speed of the car can be predicted with high accuracy by our trained user models. This opens up future possibilities of generating better personalised tracks for individuals or even real-time share-control of the car to optimally assist the users in dangerous situations.

Interaction between hairy surfaces and turbulence for different surface time scales

description: Surfaces with filamentous structures are ubiquitous in nature on many different scales, ranging from forests to micrometer-sized cilia in organs. Hairy surfaces are elastic and porous, and it is not fully understood how they modify turbulence near a wall. The interaction between hairy surfaces and turbulent flows is here investigated numerically in a turbulent channel flow configuration at $Re_τ\approx 180$. We show that a filamentous bed of a given geometry can modify a turbulent flow very differently depending on the resonance frequency of the surface, which is determined by elasticity and mass of the filaments. Filaments having resonance frequencies lower than the main frequency content of the turbulent wall-shear stress conform to slowly traveling elongated streaky structures, since they are too slow to adapt to fluid forces of higher frequencies. On the other hand, a bed consisting of stiff and low-mass filaments has a high resonance frequency and shows local regions of increased permeability, which results in large entrainment and a vast increase in drag.

Evaluating the irradiation and processing history of potential radiological device materials
Creators: name: Hodgson, Andrew Phillip James
Publisher: name: Imperial College London
Year: 2016

description: Cobalt-60 and iridium-192 sources are both generated in nuclear reactors through the irradiation of stable target materials. Variation in: neutron energy, flux and irradiation time; target material characteristics and purity; the activation cross sections of the desired neutron reactions; decay and daughter progeny in-growth; and any post-irradiation processing, can all play a key part in determining the isotopic and chemical composition of the material produced. These isotopic ratios, together with any activated elemental impurities, could potentially be used as signatures in order to provide information relating towards not only the material’s production date, but also the source’s production route, irradiation history and original elemental and isotopic composition. All of which are key indicators for material attribution in the event of a nuclear forensics incident. Computational studies to evaluate the effects of neutron flux spectra on nuclide production within these materials have indicated a number of impurity nuclides that have the potential to be used as nuclear forensics signatures. These signatures though show significant variability depending on the irradiation position and reactor conditions used. When combined with the various issues that investigations into target material purity and manufacturing conditions highlighted regarding signature development, the complexity of the problem starts to become a strong impediment towards the identification of a material’s source of origin. It is therefore unlikely that these impurity signatures could ever be used in nuclear forensics investigations, because investigators would need to know the specific processes and procedures employed by manufacturers in order to attribute materials back to their source of origin. This is an unlikely scenario based on the number of manufacturers and the variety of processes that are employed during source production.

description: Axisymmetric disks of eccentric Kepler orbits are vulnerable to an instability which causes orbits to exponentially grow in inclination, decrease in eccentricity, and cluster in their angle of pericenter. Geometrically, the disk expands to a cone shape which is asymmetric about the mid-plane. In this paper, we describe how secular gravitational torques between individual orbits drive this "inclination instability". We derive growth timescales for a simple two-orbit model using a Gauss $N$-ring code, and generalize our result to larger $N$ systems with $N$-body simulations. We find that two-body relaxation slows the growth of the instability at low $N$ and that angular phase coverage of orbits in the disk is important at higher $N$. As $N \to \infty$, the e-folding timescale converges to that expected from secular theory.

description: A hydrodynamic model involving cooling gas in the stagnation region of a collimated outflow is proposed for the formation of the giant parsec-scale bipolar envelope that surrounds the planetary nebula KjPn 8. Analytical calculations and numerical simulations are presented to evaluate the model. The envelope is considered to consist mainly of environmental gas swept-up by shocks driven by an episodic, collimated, bipolar outflow. In this model, which we call the ``free stagnation knot'' mechanism, the swept-up ambient gas located in the stagnation region of the bow-shock cools to produce a high density knot. This knot moves along with the bow-shock. When the central outflow ceases, pressurization of the interior of the envelope stops and its expansion slows down. The stagnation knot, however, has sufficient momentum to propagate freely further along the axis, producing a distinct nose at the end of the lobe. The model is found to successfully reproduce the peculiar shape and global kinematics of the giant bipolar envelope of KjPn 8.

description: Composite materials with inorganic nanoparticles were systematically investigated to prepare a highly functional composite. This study reports poly(acrylic acid) (PAA) and CaCO3 nanoparticle complexes (noted as PAA-CaCO3) that were layer-by-layer (LbL) assembled with poly(allylamine hydrochloride) (PAH) to produce (PAH/PAA-CaCO3)*n adhesive films with n deposition layers of PAH/PAA-CaCO3(n is the number of deposition cycles). Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) demonstrated that CaCO3 nanoparticles were homogeneously dispersed in (PAH/PAA-CaCO3)*n adhesive films. Polyelectrolytes repeat the “in-and-out” diffusion processes in adhesive films by exponentially growing the LbL assembly, which well disperses CaCO3 nanoparticles. Adhesive films exhibited high adhesive strength, even reaching 3.76 ± 0.67 MPa when the content of the CaCO3 nanoparticles reached 70 mol%. The results demonstrated sufficient adhesion performance for use as an adhesive in advanced optical applications. Optical transmittances of adhesive films were all greater than 87% in the visible light range. Furthermore, the refractive index (RI) increased from 1.5332 to 1.5450 with increasing CaCO3 nanoparticles content.

Fluorogenic Peptide Nucleic Acid probes for the detection of circulating microRNAs: applications to cancer diagnosis
Creators: name: Metcalf, Gavin Alan Dorman
Publisher: name: Imperial College London
Year: 2016

description: Cancer is a global burden with escalating incidence and mortality, often as a result of late diagnosis. Therefore, early detection, in order to improve prognosis and survival, remains a vital strategy for cancer management. A promising method for early diagnosis requires highly sensitive biomarkers and suitable technologies to detect them. Highly abundant in cells, microRNAs (miRNAs or miRs) play a key role as regulators of gene expression. A proportion of them are found circulating in biofluids, making them ideal non-invasive biomarkers for pathologies which aberrantly express miRNAs, such as cancer. Peptide Nucleic Acids (PNAs) are engineered uncharged oligonucleotide analogues capable of hybridising to complementary nucleic acids with high affinity and specificity. Herein, novel PNA-based fluorogenic biosensors have been designed and synthesised to target specific miRNAs that were previously identified (and in some cases already validated) as potential diagnostic biomarkers for either Prostate Cancer (PCa) (miR-141 and miR-375) or Epithelial Ovarian Cancer (EOC) (miR-132). The sensing strategy is based on oligonucleotide-template reactions (OTRs) where only the miRNA of interest serves as a matrix to catalyse an otherwise highly unfavourable fluorogenic reaction. Validated in vitro using synthetic DNA and RNA oligonucleotides, these newly developed biosensors were then shown to detect endogenous concentrations of miRNA in human blood samples, without the need for any amplification step, and with minimal sample processing. This low-cost, quantitative and versatile sensing technology has been technically validated using gold-standard RT-qPCR. Compared to RT-qPCR however, this enzyme-free, isothermal blood test is amenable to incorporation into low-cost devices or assay kits. To investigate this further three platforms were explored where out PNA probes were compartmentalised into water-in-oil micro-droplets, embedded into permeable hydrogels or immobilised onto microplates. Low-cost and highly versatile, these platforms could pave the way for new point-of-care testing or public screening tools based on miRNA detection.
Interstellar matter in Shapley-Ames elliptical galaxies. IV. A diffusely distributed component of dust and its effect on colour gradients

description: The presence of dust in elliptical galaxies has recently been shown to be quite common. Deep optical multi-colour CCD imaging has revealed the presence of dust lanes and patches, and the technique of co-adding IRAS survey scans has led to many detections of elliptical galaxies. The optical and far-infrared surveys reported similar detection rates of dust, which may indicate that dust in elliptical galaxies is generally distributed in the optically detected lanes or patches. However, we show here that the amount of dust as derived from the optical extinction values is typically an order of magnitude smaller than that derived from the IRAS flux densities, in strong contrast with the situation in spiral galaxies. To unriddle this dilemma, we postulate that the majority of the dust in elliptical galaxies exists as a diffusely distributed component which is undetectable using optical methods. Employing a multiple scattering model for the dust, we show that the presence of this newly postulated dust component implies significant radial colour gradients which were essentially thought to arise from stellar population gradients only. The energetics of the diffusely distributed dust component is shown to be consistent with the IRAS data. A comparison of the detectable amount of dust in elliptical galaxies embedded in hot, X-ray-emitting gas with the amount expected in case the production and destruction rates of dust are equal indicates that most of the dust in elliptical galaxies has been accreted from other galaxies.

description: We propose a platform to realize nodal topological superconductors in a superconducting monolayer of MoX$_2$ (X$=$S, Se, Te) using an in-plane magnetic field. The bulk nodal points appear where the spin splitting due to spin-orbit coupling vanishes near the $\pm \boldsymbol{K}$ valleys of the Brillouin zone, and are six or twelve per valley in total. In the nodal topological superconducting phase, the nodal points are connected by flat bands of zero-energy Andreev edge states. These flat bands, which are protected by chiral symmetry, are present for all lattice-termination boundaries except zigzag.

Modular verification of equivalence for memory allocating procedures
Creators: name: Wood, Timothy
Publisher: name: Imperial College London
Year: 2016

description: Verifying the equivalence of programs has been applied in many situations: for example, proving the correctness of bug-fixes, refactorings, compilation, and optimisation, proving program continuity, proving non-interference in secure information flow, proving abstraction and refinement relationships between programs, and proving that programs conform to differential privacy policies. Verifying the equivalence of heap manipulating procedures where the order and amount of memory allocations differ is challenging for state-of-the-art equivalence verifiers. We describe a fully automatic program equivalence tool, and propose a verification methodology, for such dynamically allocating programs. Recent years have seen significant progress toward fully automatic program equivalence verification, with the release of several tools taking a variety of approaches. Two main approaches are to use a weakest-precondition based program verifier or a bounded model checker. One such tool has built in support for programs that differ in the order of memory allocation, it uses a bounded model checker to discharge some proof obligations and restricts the allowable shapes of heap data structures to trees. We describe a fully automatic program equivalence verification tool for a simple object oriented language. It has a notion of procedure equivalence that is powerful enough to allow procedures with different orders and amounts of memory allocation or garbage creation to be considered equivalent, with no restrictions on heap shapes. Our tool establishes equivalence by verifying that procedures result in isomorphic heaps. The tool is built on top of an off-the-shelf weakest-precondition based verifier which itself uses an SMT solver to discharge proof obligations. A naive encoding of procedure equivalence would require the verification tool to produce a witness to the heap isomorphism before and after procedure calls, which SMT based tools are not very good at. Instead we propose a modular verification methodology, called RIE, that allows us to soundly establish heap isomorphism by checking that an approximation preserves heap equality. RIE then allows us to assume that: whenever we can establish an isomorphism between parts of stores that these stores are in fact equal, and that whenever equivalent procedures are called in an isomorphic manner their effects are equal. RIE also allows our tool to handle some cases where there is not a simulation between the recursive procedure calls of the programs being compared. We prove, and provide intuitions, that RIE is sound for a simple programming language that includes non-deterministic allocation, unbounded recursion, and unbounded heap updates.
Optical concentrator from a hyperbolic liquid crystal metamaterial

description: We examine the optical properties of two different configurations of a cylindrical device made from a hyperbolic metamaterial with optical axis defined by circular and radial director fields. The hyperbolic metamaterial is an uniaxial anisotropic medium for which the ratio between ordinary and extraordinary permittivities is negative, leading to a particular effective geometry with two timelike coordinates in the metric (Kleinian signature). By using differential geometry tools we are able to perform a comparison between a simple geometrical optics treatment and the wave formalism that shows the concentration of light along the cylinder axis for the case of the circular field configuration, whatever the injection conditions are.
