Investigation of tool-tissue interactions for application to surgical needle insertion
Creators: name: Leibinger, Alexander Philipp Manuel Erich
Publisher: name: Imperial College London
Year: 2016

description: Needle insertions are performed for a variety of medical diagnostic and therapeutic procedures, where placement accuracy has a direct influence on the effectiveness and potential injury associated to a given treatment. However, interventions in soft tissues are challenging due to the deforming anatomy, restricted view of the surgical area and restricted control of the surgical instruments. Steerable surgical needles can assist surgeons to access deep-seated targets with high accuracy, while avoiding obstacles and sensitive regions along the insertion path. One approach to this is provided by a biologically inspired needle, which is currently under development at Imperial College. The needle consists of four axially interlocked segments, enabling it to steer within a compliant medium, with bioinspired motion profiles that can result in reduced tissue deformation. This thesis aims to advance the development of this needle and to produce a better understanding of the tool-tissue interactions, which influence its ability to steer and its impact on the surrounding tissue. Experimental setups are developed for the insertion of rigid and flexible needles using tissue phantom materials and a laser based image correlation technique. For spatially resolved measurements of the material response close to the needle and at high resolution, micrometre-sized particles embedded in a tissue phantom are illuminated in a laser light sheet, and tracked using one or multiple cameras. From recorded images, displacements and strains are obtained inside the substrate to compare the extent of tissue disruption for different insertion methods. Using this technique, different phantom materials are assessed for realistic modelling of interactions, and different insertion motion profiles are evaluated to ascertain which parameters of the interaction influence needle performance. Finally, results of the deformation study and tool-tissue characterisation are employed to explore the effect of needle trajectories and insertion strategies on target motion. The thesis ends with conclusions and future work, drawn from the results on tissue phantoms, motion strategies and target motion, which can be used to improve existing models and to accelerate the development of steerable surgical tools, leading to safer and more accurate needle placement.

description: 12 W~UMa-type systems were observed at 3.6 cm with a goal to compare their radio luminosities with those of non-contact, rapidly rotating, late-type stars. Only 3 systems, all of spectral type K, have been detected. The detections and (low) upper limits for remaining systems confirm the strong under-luminosity of W~UMa-type systems. VW~Cep, which was been detected several times before, has been analyzed in terms of the temporal cumulative flux distribution. Apparently, VW~Cep spends most of the time in radio quiescence with flare-like events taking less than 20\% of time.

description: Hyperspectral imaging is an important tool having been applied in various fields, but still limited in observation of dynamic scenes. In this paper, we propose a snapshot hyperspectral imaging technique which exploits both spectral and spatial sparsity of natural scenes. Under the computational imaging scheme, we conduct spectral dimension reduction and spatial frequency truncation to the hyperspectral data cube and snapshot it in a low cost manner. Specifically, we modulate the spectral variations by several broadband spectral filters, and then map these modulated images into different regions in the Fourier domain. The encoded image compressed in both spectral and spatial are finally collected by a monochrome detector. Correspondingly, the reconstruction is essentially a Fourier domain extraction and spectral dimensional back projection with low computational load. This Fourier-spectral multiplexing in a 2D sensor simplifies both the encoding and decoding process, and makes hyperspectral data captured in a low cost manner. We demonstrate the high performance of our method by quantitative evaluation on simulation data and build a prototype system experimentally for further validation.

Power converter design for HVDC applications
Creators: name: Judge, Paul Daniel
Publisher: name: Imperial College London
Year: 2016

description: This thesis investigates the design of modular voltage source converters for High Voltage Direct Current (HVDC) applications. The first half of the thesis focuses on the design of existing multilevel HVDC technology. A design methodology for sizing modular converters for a given grid code specification, and with given design constraints in terms of peak sub-module voltage rating and capacitor size, is developed and used as the basis of comparing converter designs. Results show that the half-bridge MMC requires an energy storage in the region of 35 kJ/MVA in order to achieve a good balance between sub-module capacitor size, and required number of sub-modules. The design of the Hybrid MMC, which combines half- and full-bridge sub-modules in the design in order to achieve DC fault tolerance, is then investigated using the same design methodology, an advantage of which is that the optimum modulation index can be determined, rather than assumed. Results show that the highest efficiencies may be achievable if the converter is operated at a modulation index of 1.2. The power-loss and thermal properties of several converters are then analysed. The Alternate Arm Converter and over-modulating Hybrid MMC show the greatest efficiencies, though the AAC suffers from relatively high junction temperatures within its director switches. The potential of designing overload capability into MMCs, to enable them to provide system support services such as frequency response is then investigated. Results show 30% overload ratings may be achievable with only a 10% require increase in the number of sub-modules within the converter. System studies show that significant response improvements to the AC system can be made even if the converters need to be dynamically rated to prevent excessive junction temperatures being reached. The second half of this thesis focuses on a brand new multilevel thyristor-augmented structure called a power-group, which has the potential to allow voltage source converters that are tolerant to faults on both the AC and DC network to be constructed, while having efficiencies similar to those achievable with Current Source Converter (CSC) technology. Results show that this is possible while also retaining high quality current waveforms and independent control of real and reactive power. Results throughout the thesis are backed up by a combination of simulation and experimental work using a lab-scale multilevel converter that was constructed during the project.

An Optical/Near-Infrared Study of Radio-Loud Quasar Environments II. Imaging Results

name: Green, Richard F.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)

description: We use optical and near-IR imaging to examine the properties of the significant excess population of K>=19 galaxies found in the fields of 31 z=1-2 radio-loud quasars by Hall, Green & Cohen (1998). The excess occurs on two spatial scales: a component at <40'' from the quasars significant compared to the galaxy surface density at >40'' in the same fields, and a component roughly uniform to ~100'' significant compared to the galaxy surface density seen in random-field surveys in the literature. The r-K color distributions of the excess galaxy populations are indistinguishable and are significantly redder than the color distribution of the field population. The excess galaxies are consistent with being predominantly early-type galaxies at the quasar redshifts, and there is no evidence that they are associated with intervening MgII absorption systems. The average excess within 0.5 Mpc (~65'') of the quasars corresponds to Abell richness class ~0 compared to the galaxy surface density at >0.5 Mpc from the quasars, and to Abell richness class ~1.5 compared to that from the literature. We discuss the spectral energy distributions (SEDs) of galaxies in fields with data in several passbands. Most candidate quasar-associated galaxies are consistent with being 2-3 Gyr old early-types at the quasar redshifts of z~1.5. However, some objects have SEDs consistent with being 4-5 Gyr old at z~1.5, and a number of others are consistent with ~2 Gyr old but dust-reddened galaxies at the quasar redshifts. These potentially different galaxy types suggest there may be considerable dispersion in the properties of early-type cluster galaxies at z~1.5. There is also a population of galaxies whose SEDs are best modelled by background galaxies at z>2.5.

EBSD characterisation of heterogeneous microstructures in zirconium alloys
Creators: name: Tong, Vivian Suetto
Publisher: name: Imperial College London
Year: 2016

description: This thesis explores heterogeneous deformation and grain growth behaviour in zirconium alloys using electron backscatter diffraction techniques. Zirconium alloys are widely used for nuclear power applications and controlling microstructure during manufacture of reactor parts is critical for safe operation of the nuclear reactor. Mechanisms for the formation of abnormally large ‘blocky alpha’ grains in Zircaloy-4, which forms when annealing lightly deformed Zircaloy-4 within the alpha phase, have been explored using uniaxial compression and three point bending. The presence of blocky alpha is a known industrial problem, and adversely affects reactor safety, though there are limited studies addressing this problem. It was found that blocky alpha nucleates via strain induced grain boundary migration and grows via abnormal grain growth. In the presence of a strain gradient, blocky alpha grains nucleate in highly strained regions and grow towards lower strained regions. The final orientations of the blocky alpha grains depend on the pre-annealing strain state. High resolution electron backscatter diffraction (HR-EBSD) has been used to characterise microstructures before and after annealing to produce blocky alpha. To validate observations of increased dislocation density near grain boundaries, the effect of pattern overlap near grain boundaries on accuracy of HR-EBSD measurements is quantified. It was found that HR-EBSD measurements do not produce significant artefacts in this case. A simple calibration model and experiment is described to enable the extent of pattern overlap to be measured in other set-ups. Twinning behaviour in commercially pure zirconium was studied as a function of texture and strain rate. Twin types preferentially activated under high strain rate (10^3 s-1) and quasi-static strain rate (10^-3 s-1) were characterised using electron backscatter diffraction (EBSD) post-processing software. This software was written in-house and explanations of the algorithms used to identify twin boundaries and map intragranular misorientations have been included in this thesis.

description: We use our state-of-the-art Galaxy Evolution and Assembly (GAEA) semi-analytic model to study how and on which time-scales star formation is suppressed in satellite galaxies. Our fiducial stellar feedback model, implementing strong stellar driven outflows, reproduces relatively well the variations of passive fractions as a function of galaxy stellar mass and halo mass measured in the local Universe, as well as the `quenching' time-scales inferred from the data. We show that the same level of agreement can be obtained by using an alternative stellar feedback scheme featuring lower ejection rates at high redshift, and modifying the treatment for hot gas stripping. This scheme over-predicts the number densities of low to intermediate mass galaxies. In addition, a good agreement with the observed passive fractions can be obtained only by assuming that cooling can continue on satellites, at the rate predicted considering halo properties at infall, even after their parent dark matter substructure is stripped below the resolution of the simulation. For our fiducial model, the better agreement with the observed passive fractions can be ascribed to: (i) a larger cold gas fraction of satellites at the time of accretion, and (ii) a lower rate of gas reheating by supernovae explosions and stellar winds with respect to previous versions of our model. Our results suggest that the abundance of passive galaxies with stellar mass larger than ~10^10 Msun is primarily determined by the self-regulation between star formation and stellar feedback, with environmental processes playing a more marginal role.

The structural performance and frequency filtering effects of perforated metal to composite joints
Creators: name: Brambleby, Reuben
Publisher: name: Imperial College London
Year: 2016

description: Glass fibre reinforced polymer (GFRP) composites are becoming increasingly common place in structural load bearing applications. Many of these applications require that loads from the GFRP are transmitted to steel elements. The aim of this thesis was to investigate the performance of joints between steel and vinyl-ester GFRP, comparing the tension strength at quasi-static loading rates with that at impact loading rates. The effect of loading rate on the mode II fracture toughness of the GFRP material was also investigated in order to establish a link between the increase in joint strength under dynamic loads and the increase in mode II fracture toughness under dynamic loads. The effect that typical manufacturing flaws have on the performance of the joints was also assessed. Specimens were manufactured using the vacuum assisted resin transfer moulding process, steel adherends were co-bonded during manufacture. The investigation was undertaken using both physical tests and numerical analyses, physical tests on joints were conducted at both quasi-static and impact loading rates. The effect of loading rate on the mode II fracture toughness of vinyl-ester GFRP was investigated using four point bending end notch flexure tests at a range of loading rates. Digitial image correlation techniques were used to measure crack propagation during the end notch flexure testing. The phononic crystal behaviour of perforated steel adherends was investigated in order to demonstrate that attenuation of in-plane stress waves could be achieved at frequencies relevant to the likely joint applications . Finite element analyses and plots of the in-plane wave dispersion relations were employed for the frequency filtering studies. It was shown that the tension strength of the joints was significantly higher under impact loads than quasi-static loads and that this increase in strength could be attributed to an increase in the mode II fracture toughness of the GFRP at the higher loading rate. The perforations in the steel plates enhanced both the static and impact tension strength of the joints, the joints were found to be relatively insensitive to the types of manufacturing flaw that were assessed. It was demonstrated that finite element surface based cohesive behaviour was able to effectively simulate the debond failures in the physical specimens. The investigation into frequency filtering effects has shown that finite steel plates with resin filled perforations are capable of attenuating in-plane waves at frequencies likely to be generated during a blast event.

description: We have obtained images of the eclipsing pulsar binary PSR~B1957+20 using the Planetary Camera of the Hubble Space Telescope. The high spatial resolution of this instrument has allowed us to separate the pulsar system from a nearby background star which has confounded ground-based observations of this system near optical minimum. Our images limit the temperature of the backside of the companion to $T \simlt 2800$~K, about a factor of two less than the average temperature of the side of the companion facing the pulsar, and provide a marginal detection of the companion at optical minimum. The magnitude of this detection is consistent with previous work which suggests that the companion nearly fills its Roche lobe and is supported through tidal dissipation.

In particular, we study how to assign gauge algebras and matter content to seven-branes and their intersections, and the implication of anomaly cancellation in our construction, generalizing earlier analyses without any O7+ planes. By including O7+ planes we can realize 6d superconformal field theories hitherto unobtainable in F-theory, such as those with hypermultiplets in the symmetric representation of su. We also examine a couple of compact models. These reproduce some famous perturbative models, and in some cases enhance their gauge symmetries non-perturbatively.

From evidence to practice: the use of mathematical models to inform HIV programme planning and policy decision making
Creators: name: Case, Kelsey Kathryn
Publisher: name: Imperial College London
Year: 2016

description: From early in the HIV epidemic, mathematical models have been used to understand patterns of infection and the potential for spread and can be a valuable tool to help inform strategic decisions. This thesis aims to investigate the use of mathematical models to inform HIV programme planning and policy decision making. This is done by examining key mathematical models used for this purpose, generating recommendations to advance the utility of these models, and investigating their use in the policy environment. Quantitative and qualitative methods from epidemiology, political science and social science are used to provide an integrated global health perspective. Mathematical models are first used to investigate the long-term epidemiological implications of different policy decisions for HIV prevention and treatment in the countries most affected by HIV. Next, they are used at the national level in a country application to produce short-term projections of incidence within the population. The results from the second model are used to frame a discussion which arose at the international level regarding its use and formulates recommendations for improved use. Finally, a descriptive multi-case study investigation is conducted in Malawi and Zambia exploring the use of mathematical models in guiding national policy with respect to HIV interventions. A qualitative approach drawing on principles from grounded theory is used and a theoretical framework is developed to guide and provide structure for the investigations. This framework views research utilisation as a spectrum and considers a range of different types of use across this continuum. This chapter describes the use of modelling within the policy environment, the key stakeholders involved, and identifies the barriers, facilitators and conditions for use of modelling to inform programme planning and decision making. Taken together, this thesis progresses from global to local, taking modelling beyond the research arena and into the policy environment.

description: Chaos and complex-network based study is performed to look for signature of phase transition in Pb-Pb collision data sample at 2.76TeV per nucleon pair from ALICE Collaboration. The analysis is done on the pseudorapidity values extracted from the data of ALICE experiment and the methods used are Multifractal-Detrended-Fluctuation-Analysis(MF-DFA), and a rigorous chaos-based, complex-network based method - Visibility-Graph(VG) analysis. The fractal behavior of pionisation process is studied by utilizing MF-DFA method for extracting the Hurst exponent and Multifractal-spectrum-width to analyze the scale-freeness and fractality inherent in the fluctuation pattern of eta. Then VG method is used to analyze the fluctuation from a completely different perspective of complex network. This algorithm's scale-freeness detection mechanism to extract the Power-of-Scale-freeness-of-Visibility-Graph(PSVG), re-establishes the scale-freeness and fractality. Earlier, it has been shown that the scaling behavior is different from one hadron-nucleus($π^{-}$-AgBr(350 GeV)) to one nucleus-nucleus($^{32}$S-AgBr(200 A GeV)) interaction which is of comparatively higher total energy. In this work, we have compared the fluctuation pattern in terms of 3 rigorous parameters - Multifractal-spectrum-width, Hurst exponent and PSVG, between Pb-Pb(2.76TeV per nucleon pair) data and either of $π^{-}$-AgBr(350 GeV) or $^{32}$S-AgBr(200 A GeV) data, where both the interaction data are of significantly less energy than the ALICE data. We found that the values of the 3 parameters are substantially different for ALICE data compared to the other two interaction data. As remarkably different value of long-range-correlation indicates phase-transition, similar change in the fluctuation pattern in terms of these parameters can be attributed to a phase-transition and also the onset of QGP.

description: Recent measurements of semileptonic B-meson decays seemingly imply violations of lepton flavor universality beyond the Standard Model predictions. With three-level explanations based on extended Higgs sectors being strongly challenged by the measurements of the $B_c^-$ lifetime, new theories invoking leptoquark or vector fields appear as the only feasible answer. However, in this work we show that simple scalar extensions of the Standard Model still offer a possible solution to the $B$ physics puzzle, owing to sizeable loop-level corrections which mimic the effects of new vector contributions. Considering a simplified model characterised by a charged and a neutral scalar particle, we verify the compatibility of the observed $R_{D^{(*)}}$ signal with the relevant collider bounds. We also study an embedding of the simplified model into a three-Higgs-doublet framework, and investigate its main phenomenological constraints.

Establishment and Priority of Neospathodus bevelledi over Neospathodus yangtzeensis: Clarification and Recommendations for Future Nomenclature and Stratigraphic Naming
Creators: name: Leu, Marc
Publisher: name: Zenodo
Year: 2024

description: This comment addresses the taxonomic dispute over the priority and validity of Neospathodus bevelledi (Leu et al., 2022), in relation to Neospathodus yangtzeensis (Lyu et al., 2023). We refute the junior synonym claim made by Wu et al. (2024) based on the International Code of Zoological Nomenclature (ICZN) guidelines, highlight the formal publication and ZooBank registration of Ns. bevelledi and propose future nomenclatural corrections and biostratigraphic zone renaming. The initial mention of Ns. bevelledi in Leu's (2021) doctoral dissertation is acknowledged as an early indication of the species concept.

description: Necessary technical experience is being gained from successful construction and deployment of current prototype detectors to search for UHE neutrinos in Antarctica, Lake Baikal in Russia, and the Mediterranean. The prototype detectors have also the important central purpose of determining whether or not UHE neutrinos do in fact exist in nature by observation of at least a few UHE neutrino-induced leptons with properties that are not consistent with expected backgrounds. We discuss here the criteria for a prototype detector to accomplish that purpose in a convincing way even if the UHE neutrino flux is substantially lower than predicted at present.

description: The stellar equilibrium and collapse, including mainly white dwarfs, neutron stars and supper massive stars, is an interplay between general relativistic effects and the equation of state of nuclear matter. In the present work, we use the Chandrasekhar criterion of stellar instability by employing a large number of realistic equations of state (EoS) of neutron star matter. We mainly focus on the critical point of transition from stable to unstable configuration. This point corresponds to the maximum neutron star mass configuration. We calculate, in each case, the resulting compactness parameter, $β=GM/c^2R$, and the corresponding effective adiabatic index, $γ_{\rm cr}$. The role of the trial function $ξ(r)$ is presented and discussed in details. We found that it holds a model-independent relation between $γ_{\rm cr}$ and $β$. This statement is strongly supported by the large number of EoS and it is also corroborated by using analytical solutions of the Einstein's field equations. In addition, we present and discuss the relation between the maximum rotation rate and the adiabatic index close to the instability limit. Accurate observational measurements of the upper bound of the neutron star mass and the corresponding radius, in connection with the present predictions, may help to impose constraints on the high density part of the neutron star equation of state.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Higgs inflation scenario is one of the most compelling models of inflation at present time. It not only explains the observed data well, but also provides means to include the inflaton field within the well understood Standard Model of particle physics, without invoking any need for its extension. Despite this, due to the requirement of large non-minimal coupling to the curvature scalar of the inflaton field, or in this case the Higgs field, this model suffers from a problem often called as the `unitarity' or the `naturalness' problem. On the other hand, to address the longstanding `interpretational issue' of quantum to classical transition of the primordial modes, the collapse dynamics of quantum mechanics has recently been included into the inflationary mechanism. We show that inclusion of such collapse mechanism in Higgs inflation helps alleviate the `unitarity problem' to a great deal.

description: We investigate the properties of fakeons in quantum gravity at one loop. The theory is described by a graviton multiplet, which contains the fluctuation $h_{μν}$ of the metric, a massive scalar $ϕ$ and the spin-2 fakeon $χ_{μν}$. The fields $ϕ$ and $χ_{μν}$ are introduced explicitly at the level of the Lagrangian by means of standard procedures. We consider two options, where $ϕ$ is quantized as a physical particle or a fakeon, and compute the absorptive part of the self-energy of the graviton multiplet. The width of $χ_{μν}$, which is negative, shows that the theory predicts the violation of causality at energies larger than the fakeon mass. We address this issue and compare the results with those of the Stelle theory, where $χ_{μν}$ is a ghost instead of a fakeon.

description: Proton acceleration in nearby blazars can be diagnosed measuring their intense TeV $γ$-ray emission. Flux predictions for 1101+384 (Mrk421) and 1219+285 (ON231), both strong EGRET sources (0.1-10 GeV), are obtained from model spectra of unsaturated synchrotron pair cascades fitted to publicly available multifrequency data. An experimental effort to confirm the predicted emission in the range 1-10 TeV would be of great importance for the problems of the origin of cosmic rays, the era of galaxy formation and the cosmological distance scale.
