description: This thesis investigates social learning in large scale courses, from the perspective of exploiting the benefits of massive participation. Specifically, I examine the affordances of the FutureLearn course platform, analysing their impact on learner interactions. I then create new affordances through a novel mediating artefact, the Comment Discovery Tool, and develop innovative pedagogical models which are refined through 3 phases of design-based research. The Comment Discovery Tool is an interactive visualisation of all learner commentary that allows learners to see conversations and emergent themes from the course in a non-linear fashion. In the second phase of design-based research I use formal learning design frameworks to introduce inquiry and reflection activities into the pedagogical toolkit. These are generally missing from the established model of large scale course design which values completion, progress and retention only. The third phase of design-based research continues the pedagogical innovation by encouraging learners to alter their writing style towards the development of communities of ‘ambient affiliation’. This demonstrates that learning at scale requires a reconceptualisation of online courses, placing massive-ness and cooperation at the heart of the pedagogic design. This thesis is a case study into how this can be achieved by using design-based research, placing learners at the centre of the design process, and levelling up the human activity of learning to one where learners can extend the range of their own environment for the benefit of others. The research represents an original contribution because I demonstrate how real-time visualisations can encourage cooperative activity and demonstrate how pedagogical innovation can be achieved through a rigorous user-centric analysis, starting from the materiality of the platform, and integrating theoretical frameworks. I also use a GPL open-source licence for the tool which enables others to download, remix and re-use the technology on other courses.

description: We use the available two different self-consistent formulations of quasiparticle models and extend their applications for the description of quark gluon plasma (QGP) at non-vanishing baryon chemical potentials. The thermodynamical quantities calculated from these models are compared with the values obtained from lattice simulations and a good agreement between theoretical calculations and lattice QCD data suggests that the values of the parameters used in the paper are consistent. A new equation of state (EOS) for a gas of extended baryons and pointlike mesons is presented here which incorporates the repulsive hard-core interactions arising due to geometrical size of baryons. A first order deconfining phase transition is constructed using Gibb's equilibrium criteria between the hadron gas EOS and quasiparticle model EOS for the weakly interacting quark matter. This leads to an interesting finding that the phase transition line ends at a critical end point beyond which a crossover region exists in the phase diagram.

description: We demonstrate the ability to measure the CP-phase of a Higgs boson state by looking at the decays of heavy, Majorana neutrinos in the process $pp \to H \to N N$ at the LHC. This is shown for signals with both opposite-sign ($l^{\pm} l^{\mp} W^{\pm} W^{\mp}$) and same-sign ($l^{\pm} l^{\pm} W^{\mp} W^{\mp}$) leptonic final states. These signals are investigated in the general framework of a sequential fourth generation of fermions with an additional right-handed neutrino. Such a scenario would naturally give rise to heavy Majorana neutrinos as well as significant enhancements to Higgs production via gluon fusion due to the contributions of the new, heavy quark states running in the fermion loops. Combined with the low background inherent to a same-sign lepton signal, this could be a useful way to investigate the CP-nature of a Higgs boson state at the LHC.

Creators: name: Jeffrey, Ellen
Publisher: name: Lancaster University
Year: 2021

description: This artistic research project is concerned with the development of a noctographic movement practice using choreological principles. This practice aims to investigate the perception of rural nightscapes through movement. The practice is designed to take place at nightfall in all seasons of the year and is therefore (i) a time-specific practice, concerned with engaging with the durational and temporal qualities of a nightscape, and (ii) a site-specific practice, concerned with co-forming place through the experience of night’s darkness. The research uses choreological analysis, phenomenology and new materialism to reflect upon the experiences that individuals and communities have of a site at night. In doing so, this thesis considers how engaging with a night-time, durational movement practice – a practice in which the real and imagined, self and other, become entangled − has the capacity to transform human and more-than-human relatedness. By engaging with night as a world in which what is visually perceived no longer equates to clarity and accuracy − a world where the imagination anticipates form rather than recognises it − this artistic research endeavours to comprehend the movement of the dancer in the dark as a patterning of potentialities that compose and de-compose within the temporalities of that nightscape. Central to this practice is the inquiry as to whether, at night, movement holds within itself the potentiality to be beyond-form, as much as the dark is beyond-vision. This written thesis is accompanied by the submission of two time-specific performances: On the Patterns We Gaze, which took place 28th - 31st March 2019 in Grubbins Wood, Cumbria (vimeo.com/352720897/6088154a1c) and On the Traces We Carry, which took place April 2021, in Lancaster (vimeo.com/535227668/9b54a4e280). These performances were supported by a series of night-time movement workshops which took place from March 2018 to February 2019 in Grubbins Wood.

description: The effects of the electromagnetic (e.m.) electron-electron interactions in half-filled graphene are investigated in terms of a lattice gauge theory model. By using exact Renormalization Group methods and lattice Ward Identities, we show that the e.m. interactions amplify the responses to the excitonic pairings associated to a Kekulé distortion and to a charge density wave. The effect of the electronic repulsion on the Peierls-Kekulé instability, usually neglected, is evaluated by deriving an exact non-BCS gap equation, from which we find evidence that strong e.m. interactions among electrons facilitate the spontaneous distortion of the lattice and the opening of a gap.

description: The quantum theory of optical coherence is applied to the scrutiny of the statistical properties of the relic inflaton quanta. After adapting the description of the quantized scalar and tensor modes of the geometry to the analysis of intensity correlations, the normalized degrees of first-order and second-order coherence are computed in the concordance paradigm and are shown to encode faithfully the statistical properties of the initial quantum state. The strongly bunched curvature phonons are not only super-Poissonian but also super-chaotic. Testable inequalities are derived in the limit of large angular scales and can be physically interpreted in the light of the tenets of Hanbury Brown-Twiss interferometry. The quantum mechanical results are compared and contrasted with different situations including the one where intensity correlations are the result of a classical stochastic process. The survival of second-order correlations (not necessarily related to the purity of the initial quantum state) is addressed by defining a generalized ensemble where super-Poissonian statistics is an intrinsic property of the density matrix and turns out to be associated with finite volume effects which are expected to vanish in the thermodynamic limit.

Attributional and consequential life cycle assessment of wood chip and bark mulch use on Okanagan apple orchards, including uncertainty assessment and best practices recommendations
Creators: name: Bamber, Nicole
Publisher: name: University of British Columbia
Year: 2019

description: Food systems contribute substantially to environmental impacts, including 19-29% of greenhouse gas (GHG) emissions. The use of wood and bark chip mulch as soil cover has been proposed to reduce GHG emissions, in addition to water use and herbicide use on apple orchards. The current study expanded the scope of this prior investigation of mulch use to include all “upstream” processes for the production and transportation of the mulch used on orchards, as well as all other industrial systems that use mulch and would be impacted (i.e. through decreased availability) if mulch use on orchards were to increase. This was done using life cycle assessment (LCA), a sustainability management tool that accounts for all environmental inputs and outputs along the supply chain, or life cycle, of a product. The differences in water and herbicide use with and without mulch were not accounted for due to the experimental study design. When the orchard life cycle was considered, apples produced using mulch had higher GHG emissions than those without mulch, as well as higher impacts in all of the other impact categories considered (including acidification, eutrophication, toxicity, land and energy use). When the systems that would likely be affected by an increase in mulch use were also considered (i.e. bioenergy co-generation and paper production, the primary alternative uses of bark and wood chips in the region), the results were mixed. Some impact categories showed a benefit for mulch use on orchards and some showed a negative impact. These results also depended on whether the co-generation processes were assumed to take place in British Columbia or Washington (locations where biomass is used for co-generation). These results do not support the recommendation of mulch application on orchards as a sustainability management practice, based on the GHG mitigation benefits alone (other mulch benefits were not included). This study also demonstrates the importance of including LCA in sustainability assessment, and highlights the need for improved availability of high quality data for LCA in Canada in order to reduce uncertainty and improve the robustness of results.

description: In a recent letter [Phys. Rev. Lett. 104, 167201 (2010)] we proposed a new confining method for ultracold atoms on optical lattices, based on off-diagonal confinement (ODC). This method was shown to have distinct advantages over the conventional diagonal confinement (DC) that makes use of a trapping potential, including the existence of pure Mott phases and highly populated condensates. In this paper we show that the ODC method can also lead to temperatures that are smaller than with the conventional DC method, depending on the control parameters. We determine these parameters using exact diagonalizations for the hard-core case, then we extend our results to the soft-core case by performing quantum Monte Carlo (QMC) simulations for both DC and ODC systems at fixed temperatures, and analysing the corresponding entropies. We also propose a method for measuring the entropy in QMC simulations.

description: Mass spectrometry-based proteomics has become the tool of choice for identifying and quantifying the proteome of an organism. Though recent years have seen a tremendous improvement in instrument performance and the computational tools used, significant challenges remain, and there are many opportunities for statisticians to make important contributions. In the most widely used "bottom-up" approach to proteomics, complex mixtures of proteins are first subjected to enzymatic cleavage, the resulting peptide products are separated based on chemical or physical properties and analyzed using a mass spectrometer. The two fundamental challenges in the analysis of bottom-up MS-based proteomics are as follows: (1) Identifying the proteins that are present in a sample, and (2) Quantifying the abundance levels of the identified proteins. Both of these challenges require knowledge of the biological and technological context that gives rise to observed data, as well as the application of sound statistical principles for estimation and inference. We present an overview of bottom-up proteomics and outline the key statistical issues that arise in protein identification and quantification.

description: Structural pattern recognition describes and classifies data based on the relationships of features and parts. Topological invariants, like the Euler number, characterize the structure of objects of any dimension. Cohomology can provide more refined algebraic invariants to a topological space than does homology. It assigns `quantities' to the chains used in homology to characterize holes of any dimension. Graph pyramids can be used to describe subdivisions of the same object at multiple levels of detail. This paper presents cohomology in the context of structural pattern recognition and introduces an algorithm to efficiently compute representative cocycles (the basic elements of cohomology) in 2D using a graph pyramid. An extension to obtain scanning and rotation invariant cocycles is given.

Transcendence: boundaries, thresholds and the fourth dimension in the composite 'musical novel'
Creators: name: Monument, Liz
Publisher: name: Lancaster University
Year: 2021

description: This PhD has two parts: a composite novel (Transcendence); and an accompanying essay, which explores creative and critical strategies vital to the novel’s writing. Transcendence follows characters who cross boundaries and thresholds of different kinds, to undertake life-changing journeys: the Anglo Saxon Cwenhild must choose between art and marriage; Jules, a pregnant man, becomes the subject of an unlawful experiment; Izzy and Mei plan escape from their futuristic cities, travelling through ruined dystopian landscape and magical forest in search of freedom; and an anthrobot called Dottie reminisces about the old world which gave way to the new. Forgotten women are resurrected, as the characters’ stories overlap in chance encounters which breach boundaries and cross thresholds in space and time. Transcendence is inspired by the composite novels of David Mitchell, in its long timeline, multiple narrators, composite form, and cross-genre elements. The novel explores how all manner of boundaries and thresholds can be creatively crafted to push both narrative form and content in new directions. Transcendence is accompanied by a 20,000-word critical essay. The essay explores the musical devices I employed whilst writing (form, dissonance, silence, motif, coda and aleatoric composition), adopting Emily Petermann’s term the ‘musical novel’ to examine how these relate to fiction. I identify a beyond-boundary landscape in the fourth dimension, and suggest how Fortean aspects of the fourth dimension (ghosts, timeslips, alien abduction and the magical forest) can contribute fresh elements to story. I conclude that musical form and the fourth dimension present all kinds of boundaries and thresholds, which inspire new interpretations of structure and content in cross-genre pan-historical composite narrative.

description: We discuss gravitational magnetic bags, i.e. clusters of large number of monopoles in presence of gravitational effects. Physics depends on the dimensionless ratio between the vev of the Higgs field at infinity and the Planck mass. We solve the equations for the gravitational bags, and study the transition from monopole to black hole. The critical coupling for this transition is $v_{cr} = \sqrtπ/(4 \sqrt{G})$, and it is larger than that of a single 't Hooft-Polyakov monopole. We investigate in detail the black-hole limit.

description: We report the remarkably robust ferroelectric state in the multiferroic compound Mn$_{1-x}$Zn$_x$WO$_4$. The substitution of the magnetic Mn$^{2+}$ with nonmagnetic Zn$^{2+}$ reduces the magnetic exchange and provides control of the various magnetic and multiferroic states of MnWO$_4$. Only 5 % of Zn substitution results in a complete suppression of the frustrated collinear (paraelectric) low temperature phase. The helical magnetic and ferroelectric phase develops as the ground state. The multiferroic state is stable up to a high level of substitution of more than 50 %. The magnetic, thermodynamic, and dielectric properties as well as the ferroelectric polarization of single crystals of Mn$_{1-x}$Zn$_x$WO$_4$ are studied for different substitutions up to x=0.5. The magnetic phases have been identified in single crystal neutron scattering experiments. The ferroelectric polarization scales with the neutron intensity of the incommensurate peak of the helical phase.

description: If nonlocality is to be inferred from a violation of Bell's inequality, an important assumption is that the measurement settings are freely chosen by the observers, or alternatively, that they are random and uncorrelated with the hypothetical local variables. We study the case where this assumption is weakened, so that measurement settings and local variables are at least partially correlated. As we show, there is a connection between this type of model and models which reproduce nonlocal correlations by allowing classical communication between the distant parties, and a connection with models that exploit the detection loophole. We show that even if Bob's choices are completely independent, all correlations obtained from projective measurements on a singlet can be reproduced, with the correlation (measured by mutual information) between Alice's choice and local variables less than or equal to a single bit.

Soil and pitting corrosion of hot-dip galvanized steel : experimental and mathematical modeling
Creators: name: Nakhaie, Davood
Publisher: name: University of British Columbia
Year: 2019

description: Hot-dip galvanized steel is widely used in the electric power utility industry for power transmission and distribution structures because of its suitable service life in many atmospheric and underground conditions. The Zn coating protects the carbon steel substrate via the formation of a passive layer and by providing a sacrificial anode. Transmission towers are designed to last decades and the slow corrosion rate of the Zn coating plays an important role in assuring this service. However, under certain conditions, the corrosion rate of Zn coatings is considerable, and it may threaten the integrity of the galvanized steel structure, thus limiting its service life. Therefore, evaluating the below-grade corrosion of galvanized steel transmission towers is necessary. In this work, different experimental and analytical techniques coupled with thermodynamic and mathematical modeling were employed to evaluate the soil corrosion of hot-dip galvanized steel transmission towers. Results showed that corrosion of the Zn coated steel takes place in three successive stages, mostly in the form of localized corrosion, likely arising from the complex nature of the soil environment. Mechanistic studies of the pitting corrosion of Zn revealed that it has very different behavior than other metals, such as Fe and stainless steel. While stable pit growth of other metals strongly depends on the presence of a metal salt film, stable Zn pits can grow at potentials well below the salt film precipitation potential, most likely due to Zn’s high tendency for complexation. Once a corrosion pit is formed in the Zn coating, which can penetrate the coating and expose the steel substrate to the environment, its growth is independent of the presence of the salt film. This distinct dissolution behavior of Zn, along with the localized nature of soil corrosion of hot-dip galvanized steel, were used to develop a mathematical model to predict the soil corrosion of galvanized steel. This new model, which is based on fundamental electrochemical equations, considers all three stages of the corrosion process. The model, which dynamically considers environmental variables to calculate the corrosion rate, was validated using existing models from the literature as well as in-situ corrosion testing.

title: Novel Candidates for the Environmental Control of Photosynthesis.

Creators: name: Griffin, Jonathan
Publisher: name: Lancaster University

description: Phytochromes (phy) are key regulators of photosynthesis that act in the nucleus to orchestrate signalling pathways involved in co-ordinating plant growth and development in response to environmental cues, including light and temperature. Using publicly available transcriptomic datasets, this thesis identifies phys as master modulators for the control of nuclear genes involved in plastome gene expression mechanisms in response to red light, regulating genes involved in both the transcriptional and post-transcriptional signalling pathways. This thesis also identifies that the bZIP transcription factor HY5 may be a key transducer for phys in regulating these pathways. Among the RNA-binding proteins families that conduct the post-transcriptional regulation of the plastome are the chloroplast RNA-binding proteins (cpRNPs). Published research has shown that the cpRNPs are global modulators of plastome genes, and this thesis further identifies them as a part of an R-phyB-HY5-cpRNP signalling cascade. This thesis also shows that cpRNPs are essential to Rlight mediated greening responses in Arabidopsis thaliana and are involved in delivering light signals to the required chloroplast-encoded genes during de-etiolation. Through phyB and HY5, this thesis also shows that in addition to light quality signals, cpRNPs also integrate a diverse range of light intensity and temperature environmental signals to maintain photosynthesis. The cpRNP family has previously been characterised as regulators of the plastome but this thesis shows that they are also involved in the nucleus. Reverse genetics studies identify reductions in photosynthesis-associated nuclear-encoded gene (PhANG) transcripts in cprnp mutants, making cpRNPs a part of the co-ordination of nuclear- and plastid-encoded genes pathways for tuning photosynthesis to environmental changes. The evidence gathered here also reveals that through the phyB-modulation of alternative transcriptional start sites (TSS), cpRNP isoforms are generated with alternative nuclear subcellular localisations. Furthermore, this thesis shows that cpRNP expression is linked to retrograde signals from the chloroplast through chemical retrograde signal activator treatments affecting both cpRNP subcellular localisation and transcript accumulation. Finally, this thesis shows that the conservation of cpRNPs across higher plants makes them notable for the global efforts to generate new toolkits to maintain photosynthetic rates in crops under changing environments. This thesis describes a novel role for cpRNPs in plastid transition processes, using Solanum lycopersicum as a model crop to study chloroplast-to-chromoplast transitions.

description: We study optically driven Rabi rotations of a quantum dot exciton transition between 5 and 50 K, and for pulse-areas of up to $14π$. In a high driving field regime, the decay of the Rabi rotations is nonmonotonic, and the period decreases with pulse-area and increases with temperature. By comparing the experiments to a weak-coupling model of the exciton-phonon interaction, we demonstrate that the observed renormalization of the Rabi frequency is induced by fluctuations in the bath of longitudinal acoustic phonons, an effect that is a phonon analogy of the Lamb-shift.

description: Making use of recently released data on dihadron correlations by the STAR collaboration, I analyze the long-range ("ridge-like") part of these data and show that the dependence on both transverse momentum as well as orientation with respect to the event plane are consistent with correlations expected from only collective flow. In combination with previously analyzed centrality-dependent data, they provide strong evidence that only collective flow effects are present at large relative pseudorapidy. In contrast, by analyzing a "background subtracted" signal, the authors presenting the new data concluded that the ridge-like part of the measured correlation could not in fact be entirely generated from collective flow of the medium. I explain the discrepancy and illustrate some pitfalls of using the ZYAM prescription to remove flow background.

description: We analyze the properties of circular orbits of test particles on the equatorial plane of a rotating central mass whose gravitational field is described by the Kerr spacetime. For rotating black holes and naked singularities we explore all the spatial regions where circular orbits can exist and analyze the behavior of the energy and the angular momentum of the corresponding test particles. In particular, we find all the radii at which a test particle can have zero angular momentum due to the repulsive gravity effects generated by naked singularities. We classify all the stability zones of circular orbits. It is shown that the geometric structure of the stability zones of black holes is completely different from that of naked singularities.
