description: The $Δ$-operator of the Batalin-Vilkovisky formalism is the Hamiltonian BRST charge of Abelian shift transformations in the ghost momentum representation. We generalize this $Δ$-operator, and its associated hierarchy of antibrackets, to that of an arbitrary non-Abelian and possibly open algebra of any rank. We comment on the possible application of this formalism to closed string field theory.

description: We study the dispersion relation for scalar excitations in supersymmetric, non-commutative theories at finite temperature. In N=4 Yang-Mills the low momenta modes have superluminous group velocity. In the massless Wess-Zumino model the minimum of the dispersion relation is at non zero momentum for temperatures above T_0 ~ (g θ)^(-1\2). We briefly comment on N=2 Yang-Mills at finite density.

description: This paper proposes a low order geometrically exact flexible beam formulation based on the utilisation of generic beam shape functions to approximate distributed kinematic properties of the deformed structure. The proposed nonlinear beam shapes approach is in contrast to the majority of geometrically nonlinear treatments in the literature in which element based --- and hence high order --- discretisations are adopted. The kinematic quantities approximated specifically pertain to shear and extensional gradients as well as local orientation parameters based on an arbitrary set of globally referenced attitude parameters. In developing the dynamic equations of motion, an Euler angle parameterisation is selected as it is found to yield fast computational performance. The resulting dynamic formulation is closed using an example shape function set satisfying the single generic kinematic constraint. The formulation is demonstrated via its application to the modelling of a series of static and dynamic test cases of both simple and non-prismatic structures; the simulated results are verified using MSC Nastran and an element-based intrinsic beam formulation. Through these examples it is shown that the nonlinear beam shapes approach is able to accurately capture the beam behaviour with a very minimal number of system states.

Does airway pathology in severe preschool wheezers predict childhood asthma?
Creators: name: O’Reilly, Ruth
Publisher: name: Imperial College London
Year: 2012

description: Although one third of all preschool children wheeze, only half of these will have persistent symptoms and go on to have asthma at school age. Pathological changes characteristic of asthma, including eosinophilic inflammation and increased reticular basement membrane thickness, were evident in endobronchial biopsies from severe recurrent wheezers aged 2-3 years when compared with age matched controls. However, at the time of endobronchial biopsy it was not known which children would persistently wheeze and develop asthma at school age. The work of this thesis follows up this group of children, both preschool wheezers (n=47) and non-wheezing controls (n=21), aged between 6-11 years and establishes the presence or absence of school age asthma, relating this to pre-school airway pathology. Children (n=51) were followed up at school age, and those who attended for the research visit (n=39) were characterised in terms of atopic status, lung function (spirometry, lung clearance index) and airway inflammation (exhaled nitric oxide) at school age. Forty percent (15/37) of preschool wheezers had developed asthma at school age. Although increased airway smooth muscle is an established pathological feature of asthma in school age children, nothing is known about airway smooth muscle in preschool wheezers, hence airway smooth muscle, smooth muscle mast cells and reticular basement membrane tenascin-C were measured in the endobronchial biopsies taken at preschool age. Next, airway remodelling (increased airway smooth muscle and increased reticular basement membrane thickness) and airway inflammation at preschool age were related to the presence or absence of asthma at school age. Sixty two percent (42/68) of children had one or more evaluable biopsies for airway smooth muscle assessment. Although reticular basement membrane thickness and submucosal eosinophils were significantly higher in preschool wheezers compared with controls, they did not discriminate the children who developed asthma by school age, suggesting these airway pathological features may be associated with current symptoms rather than future asthma risk. In contrast preschool airway smooth muscle was increased in those severe preschool wheezers who went on to develop school age asthma (n=8, median age 8.2 [6-10.4] years, median ASM 0.12 [0.08-0.16]) when compared with those who did not develop asthma (n=24, median age 7.3 [5.9-11] years, median ASM 0.07 [0.02-0.23]), p=0.007. These data suggest that future studies investigating the mechanisms underlying the persistence of preschool wheeze and its development to asthma should have a primary focus on airway smooth muscle.

description: Current phenotyping and systems biology research requires not only integration of large volumes of Electronic Health Record (EHR) and multi-omics data, but also capturing the multitudes of relations among the concepts. Graph databases have emerged as a promising technology for such tasks, supporting not only local analysis but also global analysis leveraging graph algorithms like Centrality, Community Detection, Path Finding or Node Embeddings.Unfortunately, EHR data is rarely available in a graph format. While a nave row-to-node conversion is possible, the resulting graph is typically attribute-heavy, resulting in suboptimal performance. To address this limitation, we developed a modelling method to convert data form the Observational Medical Outcomes Partnership Common Data Model (OMOP CDM) to the Neo4j [www.neo4j.com] graph property model.

description: In this paper, we present an asymptotic model describing localised flexural vibrations along a structured ring containing point masses or spring-mass resonators in an elastic plate. The values for the required masses and stiffnesses of resonators are derived in a closed analytical form. It is shown that spring-mass resonators can be tuned to produce a "negative inertia" input, which is used to enhance localisation of waveforms around the structured ring. Theoretical findings are accompanied by numerical simulations, which show exponentially localised and leaky modes for different frequency regimes.

The Application of Adaptive Mesh Techniques to Convective Processes in Oceanography
Creators: name: MacTavish, Flora Pamela
Publisher: name: Imperial College London
Year: 2013

description: Idealised numerical simulations of two oceanographic processes, salt finger formation and the restratification phase of open ocean deep convection, are considered. These processes are modelled using the Imperial College Ocean Model (Fluidity-ICOM). This is a finite element code with the novel capability to perform mesh adaptivity. The mesh is triangular/tetrahedral and can be unstructured. If mesh adaptivity is used, all the fields are periodically interpolated onto a new mesh that has been optimised from the previous mesh. The new mesh is designed to represent one or more of the solution fields as accurately as possible by putting more nodes in regions where the Hessians of the fields being adapted to are higher. The first process to be presented is the formation of salt fingers in double diffusive convection. A secondary instability is observed to form. Due to the unstructured mesh, the fingers start off slightly different lengths from each other and this difference is observed to grow with time. A new set of simulations are run in which the secondary instability is initialised from a perturbation in the initial condition. These results are used to compare between fixed and adaptive mesh results. Evidence is obtained to show that adaptive mesh is able to produce the same results as the fixed mesh with fewer computational nodes because the resolution is used in the regions where is it most needed. The second process is the restratification after open ocean deep convection. In order to run ocean scale simulations the model must be able to accurately represent geostrophic and hydrostatic balance on a high aspect ratio domain. In order to do this with an unstructured mesh it is shown that it is necessary to constrain the nodes to be aligned in the vertical. This type of mesh is known as a 2+1 mesh and it can be adapted in both the vertical and the horizontal in order to resolve the solution fields more accurately. The model is able to reproduce previous results for a simple restratification test case using mesh adaptivity. The representation of balance is investigated using different types of mesh and different finite element shape functions. A more complex restratification test case in which baroclinic eddies form is then examined. The results obtained are compared to other models with different numerical schemes. Fixed and adaptive results are compared. These results demonstrate that Fluidity-ICOM is able to represent balance and model relatively complex processes on ocean scale, high aspect ratio domains whilst using mesh adaptivity.

We detect, for the first time, the broad-band spectrum of a stellar corona up to 100 keV; for Cas A we report upper limits to the ^44Ti line intensities that are lower than those available to date; for Cyg X-2 we report the evidence of a high energy component; we report a clear detection of a broad Fe K line feature from Cygnus X-1 in soft state and during its transition to hard state; Mkn 3 is one of several Seyfert 2 galaxies detected with BeppoSAX at high energies, for which Compton scattering process is important.

Modelling multiphase flow through micro-CT images of the pore space
Creators: name: Qaseminejad Raeini, Ali
Publisher: name: Imperial College London
Year: 2013

description: We present a numerical method for modelling two-phase flow through porous media directly at the pore scale. The volume of fluid method is used to capture the interface motion. The volume of fluid equation and the incompressible Navier-Stokes equations are discretised by the finite volume method using a single fluid methodology, with a discontinuity in the phase properties. Capillary forces are calculated using a new semi-sharp formulation and filtered, to allow for simulations at low capillary numbers and avoid non-physical velocities. They are applied into the Navier-Stokes equations using a semi-implicit formulation, which allows larger time steps at low capillary numbers. The numerical method is verified on several test cases, demonstrating its efficiency, stability and accuracy in modelling multiphase flow through porous media with complex interface motion and irregular solid boundaries. We present two-phase flow simulations on simple pore geometries and study the mechanisms controlling two-phase flow at the pore scale. Particularly, we study the effect of geometry and flow rate on trapping and mobilization of the non-wetting-phase. We introduce a new concept to upscale the subpore-scale forces and find the relations between the flow and the pore-scale pressure drops. These information can be used as input to pore-network models. As an example, we applied this concept to predict the threshold capillary number to prevent trapping during imbibition. Furthermore, we present two-phase flow simulations on two micro-CT images of porous media and show the effect of capillary number on the flow pattern, the trapped non-wetting phase saturation and blob sizes. We present a rigorous approach to relate the pore-scale forces controlling the flow to the Darcy-scale parameters and use it to obtain relative permeability curves. Overall, this thesis provides a methodology for a detailed pore-scale analysis of multiphase flow, serving as a rigorous foundation for large-scale modelling and prediction.
Topological Solitons in Discrete Space-Time as the Model of Fermions

Year: 2000
Subjects: subject: High Energy Physics - Theory (hep-th)

description: In the present paper we discuss arguments, favouring the view that massive fermions represent dislocations (i.e. topological solitons) in discrete space-time with Burgers vectors, parallel to an axis of time. If to put symmetrical parts of tensors of distortions (i.e. derivatives of atomic displacements on coordinates) and mechanical stresses equal zero, the equations of the field theory of dislocations get the form of the Maxwell equations. If to consider these tensors as symmetrical, we shall receive the equations of the theory of gravitation, and it turns out that the sum of tensor of distortions and pseudo-Euclidean metrical tensor is the analogue of metrical tensor. It is shown that we can also get Dirac equation with four-fermion interaction in the framework of the field theory of dislocations. This model explains quantization of electrical charge: it is proportional to the topological charge of dislocation, and this charge accepts quantized values because of discrete structure of the 4-dimensional lattice.

description: Optomechanical SiN nano-oscillators in high-finesse Fabry-Perot cavities can be used to investigate the interaction between mechanical and optical degree of freedom for ultra-sensitive metrology and fundamental quantum mechanical studies. In this work we present a nano-oscillator made of a high-stress round-shaped SiN membrane with an integrated on-chip 3D seismic filter properly designed to reduce mechanical losses. This oscillator works in the 200 kHz - 5 MHz range and features a mechanical quality factor of $Q\simeq10^7$ and a Q-frequency product in excess of $6.2 \times 10^{12}$ Hz at room temperature, fulfilling the minimum requirement for quantum ground-state cooling of the oscillator in an optomechanical cavity. The device is obtained by MEMS DRIE bulk micromachining with a two-side silicon processing on a Silicon-On-Insulator (SOI) wafer. The microfabrication process is quite flexible and additional layers could be deposited over the SiN membrane before the DRIE steps, if required for a sensing application. Therefore, such oscillator is a promising candidate for quantum sensing applications in the context of the emerging field of Quantum Technologies.

description: A pseudoclassical model is proposed for the description of planar $P,T-$invariant massive fermions. The quantization of the model leads to the (2+1)-dimensional $P,T-$invariant fermion model used recently in $P,T-$conserving theories of high-T${}_c$ superconductors. The rich symmetry of the quantum model is elucidated through the analysis of the canonical structure of its pseudoclassical counterpart. We show that both the quantum $P,T-$invariant planar massive fermion model and the proposed pseudoclassical model --- for a particular choice of the parameter appearing in the Lagrangian --- have a U(1,1) dynamical symmetry as well as an $N=3$ supersymmetry. The hidden supersymmetry leads to a non-standard superextension of the (2+1)-dimensional Poincaré group. In the quantum theory the one particle states provide an irreducible representation of the extended supergroup labelled by the zero eigenvalue of the superspin. We discuss the gauge modification of the pseudoclassical model and compare our results with those obtained from the standard pseudoclassical model for massive planar fermions.

Probing Strong Gravitational Fields in X-ray Novae
Creators: name: McClintock, Jeffrey E.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Most X-ray novae (aka soft X-ray transients) contain black hole primaries. In particular, the large mass functions measured for six X-ray novae directly clinch the argument (within general relativity) that they contain black holes. These firm dynamical results are discussed, and the urgent need to determine precise masses for black holes is stressed. The dynamical evidence for black holes is convincing but it is indirect. Now it appears that direct evidence may be at hand. Three recent studies have revealed phenomena that very likely probe strong gravitational fields: (1) a comparison of the luminosities of black hole systems and neutron star systems has yielded compelling evidence for the existence of event horizons; (2) RXTE observations of fast, stable QPOs have probed the very inner accretion disks of two black holes; and (3) three different types of low energy spectra have been linked to different black-hole spin states (e.g. Kerr vs. Schwarzschild).

We illustrate the formulation by a discussion of the Higgs mechanism and comment on the large N masterfield.

Spatio-temporal Modeling and Analysis of Brain Development
Creators: name: Serag, Ahmed
Publisher: name: Imperial College London
Year: 2012

description: The incidence of preterm birth is increasing and has emerged as a leading cause of neurodevelopmental impairment in childhood. In early development, defined here as the period before and around birth, the brain undergoes significant morphological, functional and appearance changes. The scope and rate of change is arguably greater than at any other time in life, but quantitative markers of this period of development are limited. Improved understanding of cerebral changes during this critical period is important for mapping normal growth, and for investigating mechanisms of injury associated with risk factors for maldevelopment such as premature birth. The objective of this thesis is the development of methods for spatio-temporal modeling and quantitative measures of brain development that can assist understanding the patterns of normal growth and can guide interventions designed to reduce the burden of preterm brain injury. An approach for constructing high-definition spatio-temporal atlases of the developing brain is introduced. A novelty in the proposed approach is the use of a time-varying kernel width, to overcome the variations in the distribution of subjects at different ages. This leads to an atlas that retains a consistent level of detail at every time-point. The resulting 4D fetal and neonatal average atlases have greater anatomic definition than currently available 4D atlases, an important factor in improving registrations between the atlas and individual subjects with clear anatomical structures and atlas-based automatic segmentation. The fetal atlas provides a natural benchmark for assessing preterm born neonates and gives some insight into differences between the groups. Also, a novel framework for longitudinal registration which can accommodate large intra-subject anatomical variations is introduced. The framework exploits previously developed spatio-temporal atlases, which can aid the longitudinal registration process as it provides prior information about the missing anatomical evolution between two scans taken over large time-interval. Finally, a voxel-wise analysis framework is proposed which complements the analysis of changes in brain morphology by the study of spatio-temporal signal intensity changes in multi-modal MRI, which can offer a useful marker of neurodevelopmental changes.

 uma tecitura/tessitura de autores, com o intuito de elaborar uma organização através de um
 gesto alegórico. A articulação e o mapeamento prático de uma constelação de vozes, atesta a
 estratégia de escrita não criativa e do cut-up. Estes procedimentos propõem que trechos ou
 samples sejam cortados e rearranjados de maneiras diferentes de sua ordem original, tal qual
 uma colagem dadaísta, presente tanto na obra Almoço Nu de William Burroughs, quanto nas
 composições de beatmakers de rap. The research conducted was intended to analyze and transcribe as conceptual bases of the
 creative process of my productions in Visual Arts, recombining theoretical and plastic references.
 A redirection, which offers the act of quotation, hypertextuality and remix culture, as another

 The procedures propose that excerpts or samples be cut and rearranged in ways different from

Towards Robot Learning of Tool Manipulation from Demonstrations

description: Robot learning from demonstrations (RLD), also known as imitation learning, plays an important role in human-robot interactions (HRI) because it creates a userfriendly environment for non-expert end-users to teach a robot new skills. Recent advances in sophisticated humanoid robots provide an opportunity for these robots to manipulate everyday tools. This thesis focuses on some key aspects in enabling humanoid robots to learn manipulation of tools using an RLD approach as a threefold investigation. Firstly, this work investigates the outstanding issues in existing RLD frameworks for applications in a real-world HRI environment and presents an RLD model using template-based approach integrated with an online learning algorithm to address these issues. Further investigations probe into biological systems for inspirations on improving the reusability of learned skills which results in an integrated framework using the proposed RLD model as the base model. Attention is then turned to an important aspect tightly coupled with RLD learning for tool manipulation - recognition of tools. A biologically-inspired framework based on RLD-learned tool affordance is proposed to address the issues of applying to tools the traditional static feature matching approach for object recognition. In a series of experiments, we show that our RLD model is capable of learning skills without demanding the users for repeated demonstrations. The learned skills can be generalised to similar tasks with different environmental constraints and updated as more demonstrations of the skill are presented. We also demonstrate the reusability of the complete framework in comparison to the base model by a realworld HRI application in playing the tic-tac-toe game. Through the experiments on tool recognition using a set of human demonstrations, the benchmarked performance indicates that our proposed tool representation framework is a suitable supplement to the current object recognition models on tools.
Solid oxide fuel cell microstructure and performance modeling
Creators: name: Rhazaoui, Khalil
Publisher: name: Imperial College London

description: The fundamental operation of Solid Oxide Fuel Cells (SOFCs) relies on the liberation of electrons at reaction sites within porous electrodes. These reaction sites, or triple-phase boundary (TPB) points, must be percolated to allow for reactants and products to flow to and from these sites. Due to the fact that electrochemical reactions in composite electrodes are dependent on the presence of TPB sites, a direct link exists between SOFC electrode microstructures and electrochemical performance. Recently, the development of advanced tomography and imaging techniques has allowed for this link to be better understood and quantified. This thesis presents the development of a novel effective conductivity model (ResNet) for 3D composite, anisotropic microstructures in the context of Ni-YSZ electrode characterization. The ResNet model is first used to derive the effective conductivity of simple structures, conductivities of which can be found in the literature. Good agreement was found in this initial study. The model is then used to compute the effective conductivities of more complex synthetic microstructures, comparing model outputs to those given by COMSOL Multiphysics, a commercial modeling platform. It was found that for a sufficiently high resolution, both models converge to the same results. Varying the discretization resolution allowed for an optimum discretization resolution to be determined, based on the mean particle size used for fabrication. The introduction of Volume Elements into the ResNet model is then presented, and the optimum aggregation resolution is extracted from a set of simulations. This allowed for the analysis of a real SOFC anode microstructure to be carried out, and underlined the importance of selecting a microstructure sample of a size that can be considered representative of the entire electrode. After a series of simulations on synthetically generated microstructures, several microstructural parameters are varied to carry out a sensitivity analysis on the effective conductivities and current densities of the microstructures. This analysis yielded an optimum ratio of 7 particles per structure length for microstructure size representativeness. Using the parameters derived from the studies presented in this thesis, the effective conductivities of two experimental Ni/10ScSZ anodes are extracted using the ResNet model and compared to their experimentally determined values. Excellent agreement was obtained, validating the ResNet model and associated work. In a final instance, it was shown that using the ResNet model in the electronic phase in conjunction with the VOF model developed by Golbert et al. does not yield a noticeable difference in current density output when compared to results obtained without using the ResNet. When applied to the ionic phase however, using the ResNet model in conjunction with the VOF model is found to predict as much as 50% lower computed area current densities than when the volume fraction average model is used.
Source-to-source compilation of loop programs for manycore processors

description: It is widely accepted today that the end of microprocessor performance growth based on increasing clock speeds and instruction-level parallelism (ILP) demands new ways of exploiting transistor densities. Manycore processors (most commonly known as GPGPUs or simply GPUs) provide a viable solution to this performance scaling bottleneck through large numbers of lightweight compute cores and memory hierarchies that rely primarily on software for their efficient utilization. The widespread proliferation of this class of architectures today is a clear indication that exposing and managing parallelism on a large scale as well as efficiently orchestrating on-chip data movement is becoming an increasingly critical concern for high-performance software development. In such a computing landscape performance portability -- the ability to exploit the power of a variety of manycore chips while minimizing the impact on software development and productivity -- is perhaps one of the most important and challenging objectives for our research community. This thesis is about performance portability for manycore processors and how source-to-source compilation can help us achieve it. In particular, we show that for an important set of loop-programs, performance portability is attainable at low cost through compile-time polyhedral analysis and optimization and parametric tiling for run-time performance tuning. In other words, we propose and evaluate a source-to-source compilation path that takes affine loop-programs as input and produces parametrically tiled parallel code amenable to run-time tuning across different manycore platforms and devices -- a very useful and powerful property if we seek performance portability because it decouples the compiler from the performance tuning process. The produced code relies on a platform-independent run-time environment, called Avelas, that allows us to formulate a robust and portable code generation algorithm. Our experimental evaluation shows that Avelas induces low run-time overhead and even substantial speed-ups for wavefront-parallel programs compared to a state-of-the-art compile-time scheme with no run-time support. We also claim that the low overhead of Avelas is a strong indication that it can also be effective as a general-purpose programming model for manycore processors as we demonstrate for a set of ParBoil benchmarks.
The role and diversity of Pythium and Phytophthora in UK gardens
Creators: name: Denton, Geoffrey James
Publisher: name: Imperial College London

description: Gardens are little studied particularly in relation to major plant pathogen genera such as Phytophthora, or the closely related Pythium. UK gardens harbour a wide diversity of plants of worldwide origin, compared to the relatively few native in the UK, and are frequently the endpoint of the worldwide trade in plants and sometimes, as fellow passengers their associated pathogens. Samples from a plant clinic were surveyed for the presence of Phytophthora by three methods. DNA extracted from symptomatic tissue followed by a semi-nested PCR (DEN) gave the highest detection rates with approx. 70% of tests positive. A commercial immunoassay test kit (PocketDiagnositic™) was the fastest; with results in less than 10 min. Apple baiting gave the lowest detection rates (9%), but provided cultures vital for further studies. An unexpected and novel result was the widespread detection of Pythium causing much the same symptoms as Phytophthora. The phylogenetic trees, created using the elision method, of the Phytophthora and Pythium rDNA sequences revealed 46 named or well defined species, 21 and 25 respectively. The phylogeny of both genera was in general accordance with previous publications. Frequently identified species included Ph. cryptogea, Ph. cinnamomi, Py. intermedium and Py. sylvaticum, all ubiquitous with wide host ranges. Occasional occurrences included Ph. ramorum, Ph. tropicalis, Ph. austrocedri and Ph. “niederhauseri”. Twenty putative new species were also detected, based on the Phytophthora and Pythium phylogenies, 11 and 9 species respectively. In pathogenicity tests Phytophthora and Pythium caused root rot, and Py. intermedium caused Hebe death within 3 days of soil inoculation. Not all plants infected with Phytophthora or Pythium died, indicating disease development may involve additional interactions. Pythium foliar blight of mature woody plants was identified. Koch’s postulates were satisfied, indicating new symptoms previously not associated with Pythium infections.

description: The star-matrix models are difficult to solve due to the multiple powers of the Vandermonde determinants in the partition function. We apply to these models a modified Q-matrix approach and we get results consistent with those obtained by other methods.As examples we study the inhomogenous gaussian model on Bethe tree and matrix $q$-Potts-like model. For the last model in the special cases $q=2$ and $q=3$, we write down explicit formulas which determinate the critical behaviour of the system.For $q=2$ we argue that the critical behaviour is indeed that of the Ising model on the $ϕ^3$ lattice.
