description: We study two dimensional turbulent magnetic reconnection in a compressible fluid in the gas pressure dominated limit. We use open boundary conditions and start from a Harris current sheet configuration with a uniform total pressure. A small perturbation to the vector potential initiates laminar reconnection at the Sweet-Parker rate, which is allowed to evolve for several dynamical times. Subsequently sub-Alfvenic turbulence is produced through random forcing at small wave numbers. The magnetic field topology near the current sheet is strongly affected by the turbulence. However, we find that the resulting reconnection speed depends on the resistivity. In contrast to previous results in three dimensions, we find no evidence for fast reconnection. The reconnection speed exhibits large variations but the time averages increase smoothly with the strength of the turbulence.

title: Interdisciplinarity: An Expansion of My Creative Approach
Creators: name: Garcia-Tomas, Raquel
Publisher: name: Royal College of Music

description: Over the last decade, the interest in including interdisciplinary practices within the context of contemporary music has increased. Research into this field needs to continue being addressed by composers, as well as by musicologists and art historians, in order to develop case studies which assess and define the multiple creative approaches that a project involving many artistic disciplines can have. The present research evaluates the substantial changes that have occurred in my composition practice as a consequence of using an interdisciplinary methodology –based on the transferral of methods from one discipline to another– and reflects on how an adaptive strategy, which reconsiders the preconceived compositional procedures, leads composers working within an interdisciplinary context to an integrated outcome. Given that this study has mainly been practice-based, the present commentary focuses on the composition of the following eight works: [co][hes][ion] (2013), for dance and pre-recorded electronics; Wondjina (2013), for bass clarinet, live electronics, video and dance; stone:speeches (2014), an audiovisual installation; Alice’s Adventures in Wonderland (2014), for piano, pre-recorded electronics and video-animation; disPLACE (a nowhere opera) – Història d'una casa (2015) (libretto by Helena Tornero), a chamber opera; [logolepsy/lethologica] (2016), an acousmatic work inspired by old radiophonic works; liquid:speeches (2016), a multichannel audiovisual installation; and Blind Contours no. 1 (2016), for ensemble, pre-recorded electronics and video.

description: We compute dilepton invariant mass spectra from the decays of rho mesons produced by photon reactions off nuclei. Our calculations employ a realistic model for the rho photoproduction amplitude on the nucleon which provides fair agreement with measured cross sections. Medium effects are implemented via an earlier constructed rho propagator based on hadronic many-body theory. At incoming photon energies of 1.5 -3 GeV as used by the CLAS experiment at JLAB, the average density probed for iron targets is estimated at about half saturation density. At the pertinent rho-meson 3-momenta the predicted medium effects on the rho propagator are rather moderate. The resulting dilepton spectra approximately agree with recent CLAS data.

description: Shandite with Ni$_{3}$Pb$_{2}$S$_{2}$ chemical formula and R$\bar{3}$m symmetry, contains the kagome sublattice formed by the transition metal atoms. Recent experimental results confirmed the possibility of successfully synthesizing Pd$_{3}$Pb$_{2}Ch_{2}$ ($Ch$=S,Se) with the same structure. In this paper, we theoretically investigate the dynamical properties of such compounds. Furthermore, we study the possibility of realizing Pt$_{3}$Pb$_{2}Ch_{2}$ with the shandite structure. We show that the Pd$_{3}$Pb$_{2}${\it Ch}$_{2}$ and Pt$_{3}$Pb$_{2}$S$_{2}$ are stable with R$\bar{3}$m symmetry. In the case of Pt$_{3}$Pb$_{2}$S$_{2}$, there is a soft mode, which is the source of the structural phase transition from R$\bar{3}$m to R$\bar{3}$c symmetry, related to the distortion within the kagome sublattice. We discuss realized phonon nodal lines in the bulk phonon dispersions in upper frequency modes. We show that the shandite structure can host the phonon surface states, with strong dependence by the surface kind. Additionally, chiral phonons with circular motion of the Pb atoms around the equilibrium position are realized.

HEALING AND REMODELING OF CONNECTIVE TISSUE GRAFT AROUND IMPLANTS WITH POOR KERATINIZED MUCOSA.INFLUENCE OF PROVISIONALIZATION TIMING (DELAYED VS IMMEDIATE) USING BOPT ABUTMENTS.A CLINICAL OBSERVATIONAL CONTROLLED PILOT STUDY.
Creators: name: RANCITELLI, DAVIDE
Publisher: name: Universit� degli Studi di Milano
Year: 2017

description: Aim of the study : the aim of the present study was to investigate the most effective timing of the surgical-prosthetic procedure in order to obtain a stable soft tissue augmentation around dental implants using BOPT abutments. Materials and Methods : Overall, 13 patients have been enrolled. A total amount of 21 implants have been placed and they have been alternatively assigned to the case (immediate provisionalization) or control group (delayed provisionalization) on the basis of the waiting list. The clinical criteria adopted for the enrollment in the study were the partial edentulism in which the teeth were lost at least 2 months before the date of implant placement with KM lower than 2 mm or inadequate soft tissues volume for a proper ridge contour. The two parameters evaluated for test and control groups were the apico-coronal migration and the soft tissue gain after grafting procedure. Results : gingival recession: for the control group 10 implants were analyzed between first and second evaluation. The mean difference was - 0.011 � 0.8 mm (95% CI: - 0.3 to 0.27mm). For the test group 9 implants were analyzed between first and second evaluation. The mean difference was 0.0 � 0.8mm (95% CI: - 0.35 to 0.37mm). Soft tissue gain: for the control group 8 implants were analyzed at the first evaluation. The mean augmentation was 1.17� 0.55 mm (95% CI: 1.12 to 1.45 mm). For the test group 4 implants were analyzed at the first evaluation. The mean augmentation was 0.82 � 0.52 mm (95% CI: 0.85 to 0.65 mm). Conclusions : Both the prosthetic-surgical approaches are valid in order to treat limited horizontal defects with the application of connective tissue graft without recurring to costly, invasive and long lasting guided bone regeneration procedures. Considering the lack of available information from the preliminary results it is impossible to assess which is the best therapeutic option. A total amount of 34 implants will be necessary to be able to reject the null hypothesis that the population means of the experimental and control groups are equal with probability (power) 0.8.

description: We present SPH cosmological simulations of the formation of three disk galaxies with a detailed treatment of chemical evolution and cooling. The resulting galaxies have properties compatible with observations: relatively high disk-to-total ratios, thin stellar disks and good agreement with the Tully-Fisher and the luminosity-size relations. They present a break in the luminosity profile at 3.0 +- 0.5 disk scale lengths, while showing an exponential mass profile without any apparent breaks, in line with recent observational results. Since the stellar mass profile is exponential, only differences in the stellar populations can be the cause of the luminosity break. Although we find a cutoff for the star formation rate imposed by a density threshold in our star formation model, it does not coincide with the luminosity break and is located at 4.3 +- 0.4 disk scale lengths, with star formation going on between both radii. The color profiles and the age profiles are "U-shaped", with the minimum for both profiles located approximately at the break radius. The SFR to stellar mass ratio increases until the break, explaining the coincidence of the break with the minimum of the age profile. Beyond the break we find a steep decline in the gas density and, consequently, a decline in the SFR and redder colors. We show that most stars (64-78%) in the outer disk originate in the inner disk and afterwards migrate there. Such stellar migrations are likely the main origin of the U-shaped age profile and, therefore, of the luminosity break.

Development of a framework for designing nucleic acid-based, out-of-equilibrium catalytic reaction networks.
Creators: name: Mullor Ruiz, Ismael
Publisher: name: Imperial College London
Year: 2021

description: DNA nanotechnology and Toehold Mediated Strand Displacement (TMSD) offer the possibility of building systems that display complex algorithmic behaviours. However, up to the present point most systems based in this technology act as one-shot systems that relax into equilibrium when they operate and lose any chance of responsiveness and adaptation to changing environmental outputs. This situation is starkly opposed to how living systems react to changes in their environment and implement finely-tuned responses. Cells perform this feat via biochemical transduction networks, which have previously been described as distributed computational systems operating out of thermodynamic equilibrium. While transduction networks are highly complex, their fundamental building motif is well known: the push-pull network. In this motif, a substrate is switched between two states via two fuel-consuming catalysts. This out-of-equilibrium operation allows push-pull systems to propagate information robustly in signal-transduction cascades presenting while complex dynamics. Understanding the main operational constraints of push-pull systems is a fundamental question in systems biology and a requirement for their proper use in synthetic biology. Moreover, building DNA-based analogues of push-pull systems would allow us to explore these fundamental questions and provides an ideal engineering platform for implementing non-equilibrium information processing systems in biological and nanotechnology contexts. While emulating the behaviour of transduction network in TMSD systems is possible in principle, there are several performance issues that hinder this possibility. In order to overcome these limitations, we propose the Active Circuits of Duplex Catalysts (ACDC) Framework to meet this challenge. In ACDC, all species are DNA duplexes that interact directly via four-way strand exchange. The present thesis demonstrates that the ACDC Framework can successfully implement all the prerequisite to build extended catalytic reaction networks. Additionally, we discuss functional and formal limitations of the Framework as well as the role of thermodynamic drives in overcoming them.
Uncovering genetic population structure of Puccinia coronata f. sp. avenae in Canada and identifying effective sources of resistance in oat
Creators: name: Yadav, Bharat

description: Oat crown rust (caused by the fungus Puccinia coronata var avenae f. sp. avenae) is a destructive fungal disease that causes significant yield losses in the oat crop in Canada. The genomic diversity of the pathogen population is crucial for understanding its adaptation and evolution to new hosts and environments. In this study, we aimed to (1): detect the genomic diversity of Puccinia coronata var avenae f. sp. avenae (Pca) in Canada using high-throughput sequencing data and (2): determine novel effective sources of resistance genes effective against oat crown rust among a set of 21 parental lines. The primary objective of this study is to determine whether reproducing clonal individuals in the Eastern Prairie region (Manitoba and eastern Saskatchewan) are genetically distinct from sexually reproducing individuals found in Eastern Canada (Ontario and Quebec). Genomic data from 82 Pca isolates, collected from diverse locations across Canada, were sequenced using Illumina NovaSeq6000 sequencing. Raw short sequence data of another 60 US isolates were also included in this study. Comprehensive bioinformatics pipelines were employed for quality control, mapping, and variant calling of the sequencing data. The analysis utilized four primary tools, encompassing both parametric (PCA) and non-parametric (DAPC) clustering approaches, as well as model (RAxML-NG) and non-model-based (STRUCTURE) structural analyses. Population genetic analysis revealed a relatively low level of genetic variation among the Canadian Pca population, indicating limited diversity. The population displayed distinct genetic patterns based on geographical regions, specifically the Eastern Prairie region and Eastern Canada, with discernible patterns of genetic differentiation over time, while a limited number of U.S. isolates were organized based on temporal considerations. Screening of 21 parental lines identified Leggett as the most resistant cultivar against multiple Pca isolates with virulence on 17 Pc genes, highlighting its usefulness as a parent in Canadian breeding programs. Overall, our study provides critical insights into the genomic diversity of Pca in Canada, enhancing our understanding of its evolution and adaptation to new hosts and environments. These scientific findings will serve as a foundation for developing effective strategies to combat oat crown rust in Canada.
Euler systems and arithmetic applications
Creators: name: Graham, Andrew
Publisher: name: Imperial College London
Year: 2021

description: For any p-adic Galois representation, one can attach an analytic object (the complex-valued L-function) and an algebraic object (the Bloch--Kato Selmer group), and the conjecture of Bloch and Kato describes a precise relation between these two objects. More generally, one can often formulate an "Iwasawa main conjecture" for this representation, which predicts a relation between a p-adic L-function and the inverse limit of Selmer groups in a p-adic Lie extension. In this thesis, we explore the connection between Euler systems and both of these conjectures. More precisely, in the first part of this thesis, we construct a split anticyclotomic Euler system for the Galois representation associated with a cuspidal automorphic representation of a unitary group of signature (1, 2n-1), where n is an odd integer. Combining this with the forthcoming work of Jetchev--Nekovář--Skinner, one can control the size of the Bloch--Kato Selmer group provided the bottom class of the Euler system is non-zero. In the second part of this thesis, we discuss applications of Euler systems to supersingular Iwasawa theory in the case of the convolution of two Coleman families. In particular, we obtain some partial results concerning the support of the associated Selmer sheaf and the vanishing locus of the three-variable p-adic L-function constructed by Urban. This crucially relies on the machinery of Selmer complexes as developed by Nekovář and Pottharst.

description: Using their relationship with the free boson and the free symplectic fermion, we study the off-critical perturbation of SLE(4) and SLE(2) obtained by adding a mass term to the action. We compute the off-critical statistics of the source in the Loewner equation describing the two dimensional interfaces. In these two cases we show that ratios of massive by massless partition functions, expressible as ratios of regularised determinants of massive and massless Laplacians, are (local) martingales for the massless interfaces. The off-critical drifts in the stochastic source of the Loewner equation are proportional to the logarithmic derivative of these ratios. We also show that massive correlation functions are (local) martingales for the massive interfaces. In the case of massive SLE(4), we use this property to prove a factorisation of the free boson measure.

title: Death becomes them: death doulas, gender, and advance care planning
Creators: name: Tumber, Alana
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: In Canada, non-medical professionals called “death doulas” have emerged to address perceived gaps in current models of end-of-life and funeral care by providing services that allow individuals to “reclaim” their relationship with death, by educating and supporting clients and their families about their end-of-life options concerning palliative care and funerary options. In order to understand the role of the death doula, I interviewed six death doulas from across Canada. Using a feminist phenomenological approach I explored the following questions: How do death doulas fit into a larger project of death reform? How might hegemonic beliefs about death, gender, and social privilege complicate any roles they might have in death reform movements? Relatedly, in what ways do death doulas resist or reinforce the commodification of care-work? Their responses provided a glimpse into larger debates within the death doula community regarding regulation, the validity of training programs, commodification of care, the role of the death positive movement, and the importance of education.

description: LS 5039 is one of the four TeV emitting X-ray binaries detected up to now. The powering source of its multi-wavelength emission can be accretion in a microquasar scenario or wind interaction in a young non-accreting pulsar scenario. These two scenarios predict different morphologic and peak position changes along the orbital cycle of 3.9 days, which can be tested at milliarcsecond scales using VLBI techniques. Here we present a campaign of 5 GHz VLBA observations conducted in June 2000 (2 runs five days apart). The results show a core component with a constant flux density, and a fast change in the morphology and the position angle of the elongated extended emission, but maintaining a stable flux density. These results are difficult to fit comfortably within a microquasar scenario, whereas they appear to be compatible with the predicted behavior for a non-accreting pulsar.

description: The fidelity of quantum circuits (QC) is influenced by several factors, including hardware characteristics, calibration status, and the transpilation process, all of which impact their susceptibility to noise. However, existing methods struggle to estimate and compare the noise performance of different circuit layouts due to fluctuating error rates and the absence of a standardized fidelity metric. In this work, Q-fid is introduced, a Long Short-Term Memory (LSTM) based fidelity prediction system accompanied by a novel metric designed to quantify the fidelity of quantum circuits. Q-fid provides an intuitive way to predict the noise performance of Noisy Intermediate-Scale Quantum (NISQ) circuits. This approach frames fidelity prediction as a Time Series Forecasting problem to analyze the tokenized circuits, capturing the causal dependence of the gate sequences and their impact on overall fidelity. Additionally, the model is capable of dynamically adapting to changes in hardware characteristics, ensuring accurate fidelity predictions under varying conditions. Q-fid achieves a high prediction accuracy with an average RMSE of 0.0515, up to 24.7x more accurate than the Qiskit transpile tool mapomatic. By offering a reliable method for fidelity prediction, Q-fid empowers developers to optimize transpilation strategies, leading to more efficient and noise-resilient quantum circuit implementations.

description: The 4th IBIS/ISGRI survey lists 723 hard X-ray sources many still unidentified. We cross-correlated the list of the sources included in the 4th IBIS catalogue with the Swift/XRT data archive, finding a sample of 20 objects for which XRT data could help in the search for the X-ray and hence optical counterpart and/or in the study of the source spectral and variability properties below 10 keV. Four objects (IGR J00465-4005, LEDA 96373, IGR J1248.2-5828 and IGR J13107-5626) are confirmed or likely absorbed active galaxies, while two (IGR J14080-3023 and 1RXS J213944.3+595016) are unabsorbed AGN. We find three peculiar extragalactic objects, NGC 4728 being a Narrow Line Seyfert galaxy, MCG+04-26-006 a type 2 LINER and PKS 1143-693 probably a QSO; furthermore, our results indicate that IGR J08262+4051 and IGR J22234-4116 are candidate AGN, which require further optical spectroscopic follow-up observations to be fully classified. In the case of 1RXS J080114.6-462324 we are confident that the source is a Galactic object. For IGR J10447-6027, IGR J12123-5802 and IGR J20569+4940 we pinpoint one X-ray counterpart, although its nature could not be assessed despite spectral and sometimes variability information being obtained. Clearly, we need to perform optical follow-up observations in order to firmly assess their nature. There are five objects for which we find no obvious X-ray counterpart (IGR J07506-1547 and IGR J17008-6425) or even no detection (IGR J17331-2406, IGR J18134-1636 and IGR J18175-1530); apart from IGR J18134-1636, all these sources are found to be variable in the IBIS energy band, therefore it is difficult to catch them even in X-rays.

Modelling radiation transport in high energy density systems
Creators: name: McLean, Kyle
Publisher: name: Imperial College London
Year: 2021

description: This thesis explores the calculations of radiative opacity and its use in modelling radiation transport within high energy density environments, such as those found in laboratory astrophysics and inertial confinement fusion research. Recent work has demonstrated that there may be substantial shortcomings in our current theories of opacity, which motivates a deep consideration of how current opacities are determined and how they are implemented into large scale simulations. Notably, we derive multiplicative correction factors which counteract inaccuracies that may arise due to differences in radiation and electron temperature when calculating such parameters in three-temperature radiation transport algorithms, which is relevant to modelling volume ignition experiments. The Multigroup Diffusion Algorithm for Radiation Transport (M-DART) is then introduced, which was written solely by the author for the intended purpose of providing a fast platform to model supersonic Marshak wave propagation. The M-DART algorithm is then utilised to highlight the necessary convergence steps in using multigroup diffusion algorithms to model radiation wave experiments, which probe the propagation of a Marshak wave through material. We find that computational parameters, such as poor group boundary positions, can lead to large changes in the properties of a Marshak wave, resulting in signatures which cannot be attributed solely to physical effects. M-DART is also used to explore the physical sensitivities present in a recent AWE-NIF shot which probed iron opacity under solar-relevant conditions. In doing this, an extensive insight into the important parameters which must be constrained in such an experiment are identified and analysed meticulously, providing a preliminary investigation into the feasibility of using modern M-DART along with the fast opacity code IMP and statistical methods to enhance findings within the experimental campaign. Finally, an investigation into line broadening due to intense radiation fields is documented and demonstrates that there may exist a region in temperature-density space where the broadening of spectral lines due to the presence of a radiation field could become dominant over Stark broadening and neutral broadening, which would have implications for the calculations of opacity and radiation transport in white dwarf atmospheres.

Various topics in stochastic control and measure theory: singular stochastic control, optimal stopping and decompositions of measures
Creators: name: Milazzo, Alessandro
Publisher: name: Imperial College London
Year: 2021

description: Chapter II describes my doctoral work on the problem of optimally stopping the exponential of a Brownian bridge which was posed by Ernst and Shepp in their paper [42] and was motivated by bond selling with non-negative prices. We show how to obtain an optimal stopping rule for this problem and we prove regularity of the value function and of the optimal boundary. Chapter III describes my doctoral work on problems of singular control with discretionary stopping. We develop a rigorous probabilistic study for this class of problems which leads to the dynamic programming principle. Chapter IV describes my doctoral work on some decompositions of measures and processes. In particular, we study a decomposition of measures introduced by Dellacherie from which we show how to obtain well-known decompositions of measures and processes and which we extend to vector measures.
The Crackdown on Political Dissent in Turkey After July 15, 2016. A Challenge to European Values

description: Turkey is a member of the Council of Europe, of the North Atlantic Treaty Organization, and a candidate to the accession to the European Union. As a transcontinental country, Turkey belongs both to Asia and Europe, and can be used as a benchmark to assess the narrowing of human rights and civil liberties in the fight against terrorism. While having become the central platform for action for Islamist groups in the Middle East, as a result of the gradually Islamized domestic and foreign policy of Ankara since 2011, Turkey demands its Western allies to stand by it in the fight against terrorism. Turkey has a concept of terrorism that clashes with the principles enshrined in the European Convention on Human Rights, that should be obliged to comply, together with other international instruments. The authoritarian turn put in place by the Turkish government after the failed coup d’état of 15 July 2016 is a challenge to the values of European and Western civilization, and pillories all the contradictions and the limits of the latter concerning defending fundamental human rights while countering terrorism. This paper scrutinizes the policy of the Turkish authorities to counter terrorism within the country and at its external borders, and the inconsistencies of this policy with the international legal commitments and with the values of European and Western nations.

description: Dwarf galaxies are the numerically dominating population in the dense regions of the universe. Although they seem to be simple systems at first view, the stellar populations of dwarf elliptical galaxies (dEs) might be fairly complex. Nucleated dEs are of particular interest, since a number of objects exhibit different stellar populations in their nuclei and host galaxy. We present stellar population parameters obtained from integrated optical spectra using a Lick index analysis of seven nucleated dwarf elliptical galaxies and their nuclei. After subtracting the scaled galaxy spectra from the nucleus spectra, we compared them with one another and explore their stellar populations. As a preliminary result, we find that the luminosity weighted ages of the nuclei slightly lower than those of galaxies, however, we do not see any significant difference in metallicity of the host galaxies and their nuclei.

An intelligent class : the development of a novel context capturing method for the functional auto-classification of records
Creators: name: Payne, Nathaniel
Publisher: name: University of British Columbia
Year: 2024

description: The need to accurately classify records is a core problem in many domains. Historically, the classification of records was done manually as records were received and then categorized. Unfortunately, due to a significant growth in the volume of records, the need for robust auto-classification methods that can effectively “read” and classify records, is high. Today, significant challenges remain to the development of effective auto-classification processes for records. This is because the records traditionally require functional classification based on context, not topic classification based on content. Functional classification traditionally has been a challenge for both humans and machines, with little research on how to effectively functionally classify a record. In order to move research forward, this thesis will address the challenges of both human and machine classification of records. Firstly, this thesis, will seek to evaluate the efficacy of human manual classifiers on a classification task, using knowledge from this process to articulate a process for automated functional classification that utilizes a record’s archival diplomatic context. Secondly, this thesis will compare the efficacy of manual versus machine (i.e., auto-classification) using a record set with over 500,000 records, using a novel auto-classification approach that leverages a record’s context, not just its content, to improve classification accuracy. As this thesis will discuss, there is significant variance between expert human (i.e., records managers) during the manual classification process, with statistically significant differences in their ability to accurately classify both administrative and operational records. Moreover, this thesis will demonstrate that an auto-classifier, when trained using key elements of context, can statistically outperform a group of expert human classifiers on a classification task.
The pulsating magnetosphere at Jupiter
Creators: name: Manners, Harry Arthur
Publisher: name: Imperial College London
Year: 2021

description: The study of dynamics in planetary magnetospheres is critical to a fuller understanding of the flow of mass and energy through these systems. Prominent among these dynamical features are waves occupying the ultra-low frequency (ULF) band, which represent reconfigurations forced by global-scale perturbations. These waves have been shown to establish resonances of the entire magnetosphere, exciting the normal modes of the system. Enigmatic pulsations with periods spanning 5 – 60 min have been observed in the magnetosphere at Jupiter for over forty years in various datasets, yet their relation to ULF waves and magnetospheric resonance have remained a mystery. This thesis investigates the broad range of quasi periodic ULF features at Jupiter. First, we establish that the bulk of these observations are consistent with ULF magnetohydrodynamic (MHD) waves. We use a model to demonstrate that the toroidal (east-west polarized) resonant mode is consistent with all the observations. We then present a heritage survey of all the magnetometer data available and search for large amplitude ULF waves. We show that the waves occur most often close to the magnetopause at noon and along the dusk flanks, but waves with the greatest power occur close to the plasma torus at Io’s orbit. Finally, we probe the powerful waves in the torus in greater detail. By modelling the region, we show the torus likely has independent resonance modes, with a markedly different structure than elsewhere. The work presented in this thesis establishes that ULF waves abound in the magnetosphere at Jupiter and play at least as great a role in dynamics as at Earth. Understanding the complex behaviour of the system, as revealed by the ongoing Juno mission and to be followed up by the forthcoming JUICE mission, will require yet greater investigations into ULF phenomena.
