description: We present an analysis of cosmological models with mixed dark matter (spectrum slope of density perturbations $n_S \in [0.6, 1.6]$, hot dark matter abundance $Ω_ν\in [0.0, 0.6]$) in spatially flat Universe, based on Press-Schechter formalism (P\&S). We found that the models with $n_S > 1$ and $Ω_ν< 0.5$ are preferable. Additionally, for all considered models we simulated $ΔT/T\vert_{10^0}$ and compared it with the COBE measured amplitude of CMB anisotropy. We found that the models favourable for galaxy cluster abundance need large amount of cosmological gravitational waves (T/S $> 1$).

description: The F-statistic is an established method to search for continuous gravitational waves from spinning neutron stars. Prix et al. (2011) introduced a variant for transient quasi-monochromatic signals. Possible astrophysical scenarios for such transients include glitching pulsars, newborn neutron stars and accreting systems. Here we present a new implementation of the transient F-statistic, using pyCUDA to leverage the power of modern graphics processing units (GPUs). The obtained speedup allows efficient searches over much wider parameter spaces, especially when using more realistic transient signal models including time-varying (e.g. exponentially decaying) amplitudes. Hence, it can enable comprehensive coverage of glitches in known nearby pulsars, improve the follow-up of outliers from continuous-wave searches, and might be an important ingredient for future blind all-sky searches for unknown neutron stars.

Vaccinia virus protein C4 is an inhibitor of NF-κB activation and contributes to virulence
Creators: name: Ember, Stuart William John
Publisher: name: Imperial College London
Year: 2012

description: Vaccinia virus (VACV) expresses many proteins that subvert the host innate immune response and this thesis describes the characterisation of C4, a VACV protein unstudied hitherto, which was hypothesised to have such a role. C4 is conserved in six orthopoxvirus species and shares 43.7% amino acid identity to VACV protein C16, a known virulence factor. C4 is an intracellular protein that is expressed early during infection and localises to both the cytoplasm and nucleus. Functional screens revealed C4 is an inhibitor of IFNβ promoter activation via the inhibition of NF-κB activation. Mechanistically, this inhibition is attributable to the prevention of IκBα phosphorylation. Consistent with this mode of action, C4 coprecipitated with the canonical IKK proteins, IKKβ and NEMO. Protein C16 and the icIL-1Ra were also found to inhibit NF-κB activation. Furthermore, C4 is an inhibitor of cytoplasmic DNA sensing in MEFs and interacts with Ku70 and Ku80 (Ku), two components of the DNA sensor, DNA-PK. Another novel discovery is that VACV infection leads to the stabilisation and translocation of HIF-1α. This process is largely dependent on C16, however C4 is also required for maximal HIF-1α stabilisation and transactivation. The role of HIF-1α during infection and the mechanism used by C4 to contribute to its stabilisation process require further investigation. Whilst C4 is non-essential for virus replication and spread in cell culture, its deletion does result in reduced virus virulence in a murine intranasal model of infection. Finally, the deletion of both C16 and C4 lead to a synergistic attenuation of virus virulence in both the intranasal and intradermal models of infection.

Impact of the Galactic Disk and Large Magellanic Cloud on the Trajectories of Hypervelocity Stars Ejected from the Galactic Center

description: We consider how the gravity of the Galactic disk and the Large Magellanic Cloud (LMC) modifies the radial motions of hypervelocity stars (HVSs) ejected from the Galactic Center. For typical HVSs ejected towards low (high) Galactic latitudes, the disk bends trajectories by up to 30 degrees (3-10 deg). For many lines-of-sight through the Galaxy, the LMC produces similar and sometimes larger deflections. Bound HVSs suffer larger deflections than unbound HVSs. Gravitational focusing by the LMC also generates a factor of two overdensity along the line-of-sight towards the LMC. With large enough samples, observations can detect the non-radial orbits and the overdensity of HVSs towards the LMC. For any Galactic potential model, the Galactic rest-frame tangential velocity provides an excellent way to detect unbound and nearly bound HVSs within 10 kpc of the Sun. Similarly, the rest-frame radial velocity isolates unbound HVSs beyond 10-15 kpc from the Sun. Among samples of unbound HVSs, measurements of the radial and tangential velocity serve to distinguish Galactic Center ejections from other types of high velocity stars.

The role of electron orbital angular momentum in the Aharonov-Bohm effect revisited

description: This is a brief review on the theoretical interpretation of the Aharonov-Bohm effect, which also contains our new insight into the problem. A particular emphasis is put on the unique role of electron orbital angular momentum, especially viewed from the novel concept of the physical component of the gauge field, which has been extensively discussed in the context of the nucleon spin decomposition problem as well as the photon angular momentum decomposition problem. Practically, we concentrate on the frequently discussed idealized setting of the Aharonov-Bohm effect, i.e. the interference phenomenon of the electron beam passing around the infinitely-long solenoid. One of the most puzzling observations in this Aharonov-Bohm solenoid effect is that the pure-gauge potential outside the solenoid appears to carry non-zero orbital angular momentum. Through the process of tracing its dynamical origin, we try to answer several fundamental questions of the Aharonov-Bohm effect, which includes the question about the reality of the electromagnetic potential, the gauge-invariance issue, and the non-locality interpretation, etc.

Simulation and characterization of optical nanoantennas for field enhancement and waveguide coupling
Creators: name: Fernandez Garcia, Roberto
Publisher: name: Imperial College London
Year: 2013

description: Optical antennas are nanostructures designed to efficiently convert free-propagating optical radiation to localized energy and vice versa. They are based on localized surface plasmon resonances (LSPRs) that generally exist in metal nanoparticles (NPs). The excitation of LSPRs can lead to large near field enhancements and to an increase of the near field effective area up to several times the physical cross section of the nanoparticle. These properties can be used to increase the interaction of any object located in their vicinity with free space radiation. In this thesis, we investigate experimentally and numerically the interactions of nanoantennas with different systems like organic emitters, graphene and dielectric waveguides. we have numerically reviewed important experimental factors that generally control the optical antennas properties. Substrates, metal sticking layers, geometries or dimensions can significantly influence the maximum near field enhancement and the resonance wavelength that optical antennas can provide for spectroscopies like Surface enhanced Raman Scattering, (SERS) and Photoluminiscence, (PL). In particular, we experimentally analyse the influence of the incorporation of a metallic reflecting layer. This provide a straightforward way to increase the photoluminescence enhancement of nanoemitters induced by optical nanotantennas. Regarding SERS applications, we probe with surface-enhanced Raman scattering the plasmonic properties of an isolated Au double disk nanostructure interfaced with suspended graphene. By rotating the polarization of the excitation, we switch between the dots acting as single plasmonic particles and a coupling regime, realizing a plasmonic cavity. we observe a Raman intensity enhancement of the order of 1000 resulting from the near- field enhancement at the antenna cavity.

description: If Coniaci is a reference to Kōnkaṇ, then Strabo’s Geographica (1st century BC) would be the first historical text to mention Kōnkaṇ. [Hamilton, 1857 :The Geography of Strabo, Ch. I, Bk. XV, 80] The next could possibly be that of Pliny (1st century CE). Pliny describes India in Chapter 23 of his encyclopedia titled Naturalis Historia: “After these we come to the nation of the Pandæ, the only one throughout all India which is ruled by women. … After passing through this list of three hundred towns, we come to the Darangæ, the Posingæ, the Butæ, the Gogaræ, the Umbræ, the Nereæ, the Brancosi, the Nobundæ, the Cocondæ, the Nesei, the Palatitæ, the Salobriasæ, and the Orostræ, … .” [Bostock& Riley, 1755 :The Natural History of Pliny, 48] Could Cocondæ be a reference to Kōnkaṇ ? Prima facie it does not seem to fit the geographical position of Kōnkaṇ. Before coming to the ‘nation of Pandæ’, Pliny describes the Nareæ. Jean Hardouin who edited Pliny’s Natural History in late 17th century identifies Nareæ as probably the people occupying the southern part of the peninsula or the Deccan, with the Malabar and Coromandel coasts. After several more ‘nations’, Pliny comes to the Pandæ, whom Hardouin identifies as the people inhabiting the Peninsula of Gujarat. From here Pliny passes to River Indus. Pliny’s Cocondæ, therefore appears to lie somewhere between Gujarat and Sind. The location of Cocondæ according to Pliny would fit Kōnkaṇa only if his Pandæ refers to the Pandyan Kingdom (with Madurai as its capital) that covered parts of South India between 600 BCE and 13th century CE. The northern tip of the Pandyan kingdom is believed to have touched Mangaluru. Then Pliny’s sequence of places - Pandæ =>Cocondæ - seems to be appropriate.

description: The current ways in which documents are made freely accessible in the Web no longer adhere to the models established Budapest/Bethesda/Berlin (BBB) definitions of Open Access (OA). Since those definitions were established, OA-related terminology has expanded, trying to keep up with all the variants of OA publishing that are out there. However, the inconsistent and arbitrary terminology that is being used to refer to these variants are complicating communication about OA-related issues. This study intends to initiate a discussion on this issue, by proposing a conceptual model of OA. Our model features six different dimensions (prestige, user rights, stability, immediacy, peer-review, and cost). Each dimension allows for a range of different options. We believe that by combining the options in these six dimensions, we can arrive at all the current variants of OA, while avoiding ambiguous and/or arbitrary terminology. This model can be an useful tool for funders and policy makers who need to decide exactly which aspects of OA are necessary for each specific scenario.

description: Quantum Cascade Lasers (QCLs) are generally designed to avoid negative differential conductivity (NDC) in the vicinity of the operation point in order to prevent instabilities. We demonstrate, that the threshold condition is possible under an inhomogeneous distribution of the electric field (domains) and leads to lasing at an operation point with a voltage bias normally attributed to the NDC region. For our example, a Terahertz QCL operating up to the current maximum temperature of 199 K, the theoretical findings agree well with the experimental observations. In particular, we experimentally observe self-sustained oscillations with GHz frequency before and after threshold. These are attributed to traveling domains by our simulations. Overcoming the design paradigm to avoid NDC may allow for the further optimization of QCLs with less dissipation due to stabilizing background current.

The Pedagogy Of The Operating Theatre
Creators: name: Cope, Alexandra Clare
Publisher: name: Imperial College London
Year: 2013

description: This thesis outlines the findings of a large body of research work undertaken during 3 years of full-time study. The findings have already provided the author with helpful anchors for structuring formative feedback to surgical trainees within a simulation program, as well as helpful insights into her own learning. This thesis explores the operating theatre as a teaching and learning environment for postgraduate surgical trainees. The work crosses paradigms and uses contrasting methodologies to provide rich insights into surgical pedagogic practice. The first chapter is an introduction to the subject material, outlining the thesis aims and research questions, making clear why the research is important. The perspectives of the researcher are explained, in the first person, to make explicit her background and epistemological stance. The next chapter presents a narrative review of the literature, providing a background to the subject and a theoretical framework. Chapters three to six constitute empirical work. The third and fourth chapters use a grounded theory method to explore surgeons’ perceptions of the content and process of learning in the operating theatre. Chapter five uses case study methodology to illustrate teaching and learning in the operating theatre with concrete examples of pedagogic practice. The sixth chapter is a quasi-experimental study of learning which makes comparison between different pedagogic styles. The final chapter of the thesis draws together the findings from the empirical investigations. The personal development of the researcher is discussed in the first person and the body of research work is critically examined in view of its contribution to the field and its implications for future educational innovation.

description: Magnetic field-aligned electric fields are characteristic features of magnetic reconnection processes operating in externally agitated magnetized plasmas. An especially interesting environment for such a process are the coronae of accretion disks in active galactic nuclei (AGN). There, Keplerian shear flows perturb the quite strong disk magnetic field leading to intense current sheets. It was previously shown that given field strengths of 200 G in a shear flow, reconnection driven magnetic field aligned electric fields can accelerate electrons up to Lorentz factors of about 2000 in those objects thus providing us with a possible solution of the injection (pre-acceleration) problem. However, whereas in the framework of magnetohydrodynamics the formation of the field-aligned electric fields can be described consistently, the question has to be addressed whether the charged particles can really be accelerated up to the maximum energy supplied by the field-aligned electric potentials, since the accelerated particles undergo energy losses either by synchrotron or inverse Compton mechanisms. We present relativistic particle simulations starting from electric and magnetic fields obtained from magnetohydrodynamic simulations of magnetic reconnection in an idealized AGN configuration including nonthermal radiative losses. The numerical results prove that the relativistic electrons can be effectively accelerated even in the presence of an intense radiation bath. Energies from 50 MeV up to 40 GeV can be reached easily, depending on the energy density of the photon bath.

Seismic Full-Waveform Inversion of 3D Field Data – From the Near Surface to the Reservoir
Creators: name: Nangoo, Tenice Peaches
Publisher: name: Imperial College London
Year: 2013

description: The theory of FWI is well-established. However its practical application to 3D seismic datasets is still a subject of intense research. This technique has shown spectacular results in quantitatively extracting P-wave velocities in the shallow near surface at depths of less than 1 km, using wide-angle OBC datasets. This study deals with establishing a robust methodology for the application of FWI that can be routinely applied to analogous field datasets, both in the shallow near surface and at deeper reservoir depths. A practical strategy for anisotropic 3D acoustic FWI was developed and implemented. The stratergy is tested on a series of 3D datasets: (1) a synthetic Marmousi dataset, (2) an OBC field data and (3) a streamer data. A 3D synthetic Marmousi data is used to compare FWI implementations in both the time domain and the frequency domain. In both domains, it was possible to recover an almost ‘perfect’ model with complete data coverage, no noise, and few iterations. Both approaches were useful and competitive, and ideally both should be available within a comprehensive suite of inversion tools. The anisotropic time-domain FWI strategy was successfully implemented to complex OBC field data set with long offsets, full-azimuthal coverage and low frequencies. The FWI quantitatively recovered p-wave velocities in the shallow near surface, at intermediate depths where the sediments are gas bearing, and at deeper reservoir depths. The velocities are indeed realistic and are consistent with an independent reflection PSDM volume, well data and pressure data. The synthetic FWI data better match the field data, with the phase residuals between the two datasets significantly reduced to low values. The gathers are flatter and the depth-migrated images are more resolved and focused. The strategy was also successfully implemented to complex streamer field data set with short offsets, narrow-azimuthal coverage and reduced signal at the low frequencies. The FWI quantitatively recovered P-wave velocities down to depths of 750 m. A complex series of high and low velocity channels are recovered. These are consistent with an independent reflection PSTM volume. The synthetic FWI data better match the field data, with the phase residuals between the two datasets significantly reduced to low values. The depth-migrated images are more resolved and focused in the shallow section.

description: Context. Astrometric microlensing is an excellent tool to determine the mass of a stellar object. By measuring the astrometric shift of a background source star in combination with precise predictions of its unlensed position and of the lens position, gravitational lensing allows to determine the mass of the lensing star with a precision of 1 percent, independent of any prior knowledge. Aims. Making use of the recently published Gaia Data Release 2 (Gaia DR2) we predict astrometric microlensing events by foreground stars of high proper motion passing by a background star in the coming years. Methods. We compile a list of ~148.000 high-proper-motion stars within Gaia DR2 with $μ_{tot}$ > 150 mas/yr. We then search for background stars close to their paths and calculate the dates and separations of the closest approaches. Using color and absolute magnitude, we determine approximate masses of the lenses. Finally, we calculate the expected astrometric shifts and magnifications of the predicted events. Results . We detect two ongoing microlensing events by the high proper motion stars Luyten 143-23 and Ross 322 and predict closest separations of (108.5 $\pm$ 1.4) mas in July 2018 and (125.3 $\pm$ 3.4) mas in August 2018, respectively. The respective expected astrometric shifts are (1.74 $\pm$ 0.12) mas and (0.76 $\pm$ 0.06) mas. Furthermore, Luyten 143-23 will pass by another star in March 2021 with a closest separation of (280.1 $\pm$ 1.1) mas, which results in an expected shift of (0.69 $\pm$ 0.05) mas.

description: Statistical average of the axial current is evaluated on the basis of the covariant Wigner function. In the resulting formula, chemical potential $μ$, angular velocity $Ω$ and acceleration $a$ enter in combination $μ\pm (Ω\pm ia)/2$. The limiting cases of zero mass and zero temperature are investigated in detail. In the zero-mass limit, the axial current is described by a smooth function only at temperatures higher than the Unruh temperature. At zero temperature, the axial current, as a function of the angular velocity and chemical potential, vanishes in a two-dimensional plane region.

Quadtree Structured Approximation Algorithms
Creators: name: Scholefield, Adam
Publisher: name: Imperial College London
Year: 2013

description: The success of many image restoration algorithms is often due to their ability to sparsely describe the original signal. Many sparse promoting transforms exist, including wavelets, the so called ‘lets’ family of transforms and more recent non-local learned transforms. The first part of this thesis reviews sparse approximation theory, particularly in relation to 2-D piecewise polynomial signals. We also show the connection between this theory and current state of the art algorithms that cover the following image restoration and enhancement applications: denoising, deconvolution, interpolation and multi-view super resolution. In [63], Shukla et al. proposed a compression algorithm, based on a sparse quadtree decomposition model, which could optimally represent piecewise polynomial images. In the second part of this thesis we adapt this model to image restoration by changing the rate-distortion penalty to a description-length penalty. Moreover, one of the major drawbacks of this type of approximation is the computational complexity required to find a suitable subspace for each node of the quadtree. We address this issue by searching for a suitable subspace much more efficiently using the mathematics of updating matrix factorisations. Novel algorithms are developed to tackle the four problems previously mentioned. Simulation results indicate that we beat state of the art results when the original signal is in the model (e.g. depth images) and are competitive for natural images when the degradation is high.
Influence of Epoxy Spray Binder on Infusion and Cure in Liquid Composite Molding Processes

description: Binders are known to influence the different steps in liquid composite molding process chains. Most reseach focuses on powder binder and veils. Spray binders are rarely studied. Therefore, the effect of an epoxy spray binder on the infusion and cure steps of liquid composite molding processes is studied in this paper. Permeability measurements, solubility tests and measurements of glass transition temperature, resin cure time and resin viscosity show a complex interaction between binder and resin depending on the process conditions. The binder mostly increased the permeability of the tested preforms. This effect increases with increasing binder loading. At low fiber volume fractions the binder had a positive effect on preform permeability, most likely by to delaying the closure of macro flow channels or textile inhomogeneity. The binder did not dissolve in the resin until temperatures of around 120 °C, while remaining as a separate phase at 22 °C, 40 and 80 °C. This has to be considered when defining the cure profile of the resin, as the binder is expected to participate in the cure reaction. The glass transition temperature remained unchanged for the binder-resin combination used. An increase in viscosity by a factor of 1.5-2 was observed when the binder was dissolved in the resin. Samples with dissolved binder cured slightly faster than pure resin. The experimental results were theoretically transferred to real infusion processes.
Scalable verification techniques for data-parallel programs

Publisher: name: Imperial College London
Year: 2014

description: This thesis is about scalable formal verification techniques for software. A verification technique is scalable if it is able to scale to reasoning about real (rather than synthetic or toy) programs. Scalable verification techniques are essential for practical program verifiers. In this work, we consider three key characteristics of scalability: precision, performance and automation. We explore trade-offs between these factors by developing verification techniques in the context of data-parallel programs, as exemplified by graphics processing unit (GPU) programs (called kernels). This thesis makes three original contributions to the field of program verification: 1. An empirical study of candidate-based invariant generation that explores the trade-offs between precision and performance. An invariant is a property that captures program behaviours by expressing a fact that always holds at a particular program point. The generation of invariants is critical for automatic and precise verification. Over a benchmark suite comprising 356 GPU kernels, we find that candidate-based invariant generation allows precise reasoning for 256 (72%) kernels. 2. Barrier invariants: a new abstraction for precise and scalable reasoning about data-dependent GPU kernels, an important class of kernel beyond the scope of existing techniques. Our evaluation shows that barrier invariants enable us to capture a functional specification for three distinct prefix sum implementations for problem sizes using hundreds of threads and race-freedom for a real-world stream compaction example. 3. The interval of summations: a new abstraction for precise and scalable reasoning for parallel prefix sums, an important data-parallel primitive. We give theoretical results showing that the interval of summations is, surprisingly, both sound and complete. That is, all correct prefix sums can be precisely captured by this abstraction. Our evaluation shows that the interval of summations allow us to automatically prove full functional correctness of four distinct prefix sum implementations for all power-of-two problem sizes up to 2^{20}.

description: The effect of polymer coating on MNR relaxometry of maghemite nanoparticles has been studied. The samples were carefully sorted by size in order to reach narrow size distribution (<0.2) with size ranging from 4.5 to 12.5 nm. Relaxation dispersion profile as well as studies at a fixed Larmor frequency, were recorded for numerous either uncoated or polymer coated samples. The NMR relaxivities r1 and r2 increase with nanoparticle diameter. We have analysed the role of polydispersity for nanoparticles with the same mean size on the dispersion curves. We have compared the role of coating on nanoparticles NMR relaxivity between bare and poly(sodium acrylate-co-maleate) coated nanoparticles. We have investigated the influence of nanoparticle size on the T1 and T2 activation energy Ea. While Ea decreases with nanoparticle diameter when determined from T1, it increases from T2 determination. The influence is more important for small particles (<9 nm) than for big particles (>9 nm). Moreover, the PAAMA coating changes the energy Ea obtained from T2: Ea becomes independent of the nanoparticle diameter. These results highlight the need of a complete characterisation of the role of the coating on the relaxation of magnetic particles.

description: We demonstrate the presence of modular properties in partition functions of $T\bar{T}$ deformed conformal field theories. These properties are verified explicitly for the deformed free boson. The modular features facilitate a derivation of the asymptotic density of states in these theories, which turns out to interpolate between Cardy and Hagedorn behaviours. We also point out a sub-sector of the spectrum that remains undeformed under the $T\bar{T}$ flow. Finally, we comment on the deformation of the CFT vacuum character and its implications for the holographic dual.
