Analysis of images of the human retina
Creators: name: Witt, Nicholas William
Publisher: name: Imperial College London
Year: 2019

description: The microvasculature is implicated in the development of cardiovascular disease, and the eye offers a unique window through which the retinal microvasculature can be imaged and evaluated. Retinal fundus photography allows computer aided quantitative measurements characterising vascular geometry that are believed to relate to vascular disorder and cardiovascular risk. Measurement of vessel diameters from non-fluorescein images is challenging for numerous reasons. A novel measurement technique, the Sliding Linear Regression Filter (SLRF) is proposed to overcome deficiencies in earlier approaches, and confidence gained in its performance by comparison with manual measurements by a skilled clinician. Non-dimensional parameters are preferred to characterise the vascular geometry to avoid dependence on refraction of the eye. Departure of diameter relationships from optimal conditions at arterial bifurcations is hypothesised to indicate endothelial dysfunction and to predict risk of atherogenesis and cardiovascular risk. Other parameters of interest include vascular length/diameter ratios and tortuosity. A computer based semi-automatic grading tool using the SLRF method has been developed and applied to images from the Beaver Dam Eye Study in a prospective case-control study to explore associations between retinal vascular geometry and incident death from ischemic heart disease (IHD) and stroke over a 10 year period. Results were obtained from 126 IHD and 28 stroke cases, together with 528 age and gender matched controls. Disordered arterial bifurcation optimality was associated with death from IHD, consistent with the underlying hypothesis. Furthermore, this association appears independent of other recognised risk factors, suggesting that it adds additional prognostic value. Elevated conventional arterial L/D ratio was associated with death from stroke, but this association was not maintained after adjustment for systolic blood pressure. An interesting but unexpected association between reduced simple tortuosity and death from IHD was found, although this should be treated with some caution, due to eccentricities in behaviour of this parameter.

Critical local damage scenarios for robustness assessment of irregular structures
Creators: name: Grosman, Stanyslav
Publisher: name: Imperial College London
Year: 2019

description: Modern-day architects tend to use singular and non-repeatable shapes for building structures. Currently, scenarios for robustness assessment of such structures are defined based on engineering judgement, which can result in designs that are insufficiently robust. This thesis focuses on development of a rigorous robustness assessment framework capable of reliably determining critical scenarios for irregular building structures. To reduce the computational demand associated with analysis of detailed numerical models of building structures undergoing robustness assessment, a novel shell element capable of effectively modelling reinforced concrete slabs under extreme loading conditions is developed. A comparative study conducted in this work demonstrates the computational efficiency of the new element without compromising the accuracy of the modelled response. To address the needs of robustness assessment in the early design stage, a gradient based methodology, founded on the general concepts of topology optimisation, is developed. This methodology is capable of determining critical zones of the considered structure efficiently and to obtain a good estimate of its robustness. The developed methodology is based on an enhancement of the robustness assessment framework developed at Imperial College London, enabling a rational evaluation of robustness for sudden local damage scenarios. To facilitate the convergence of the developed procedure, a simple yet reasonably accurate approach for estimating the sensitivity of the robustness measure to the changes in damage parameters is developed and verified. To provide a reliable framework for estimating robustness at the final stage of design, an efficient global approach based on a meta-modelling technique is developed within the robustness assessment framework. This approach benefits from the developed variant of multifidelity kriging algorithm. The proposed modification utilises a set of independent low fidelity models, obtained through the subdivision of the high-fidelity model into a set of a priori established components. Employing the developed approach these models can be assembled to construct a composite low fidelity model for the response of the whole structure. The developed framework is finally applied in a detailed case study to the robustness assessment of the Agora Garden Tower. This study successfully identified all of the critical scenarios as well as their respective robustness measures. The results of the robustness assessment indicated that concepts commonly accepted for the regular structures do not necessarily hold for specific types of irregular ones, which provides strong support to the original motivation for the conducted research.

Understanding and controlling uniaxial negative thermal expansion in Ruddlesden–Popper oxides
Creators: name: Ablitt, Christopher
Publisher: name: Imperial College London
Year: 2019

description: Most materials expand when heated, yet there exist some that contract – a rare phenomenon known as negative thermal expansion (NTE). Uniaxial NTE has been observed over a pronounced temperature range in certain phases of several Ruddlesden-Popper oxides, which are layered perovskites with general formula An+1BnO3n+1 that are characterised by their layer thickness, n. Despite being renowned for possessing many interesting functional properties, ABO3 perovskites, which form the n = • limit of the Ruddlesden–Popper series, rarely exhibit NTE of this kind and over such a wide temperature range. A central theme of this thesis is thus to establish the origin of uniaxial NTE and discover why it is prevalent only in particular phases of low n Ruddlesden–Popper oxides. Since tunability has become a paradigm in the field of functional ceramics, a further aim is to develop ways to engineer oxides with controllable NTE. This thesis presents mainly the results of first-principles simulations, but also analysis of experimental data and mechanical models to achieve these aims. It is found that uniaxial NTE arises from the combined effects of octahedral tilt vibrations and anisotropic elastic compliance. This compliance is unique to the NTE phase of low n Ruddlesden–Popper oxides and I propose an atomistic model, the corkscrew mechanism, to explain it based on structural arguments. I also find that the magnitude of NTE in Ruddlesden–Popper oxides may be tuned in two ways: by varying the layer thickness – which changes the elasticity; and by altering the chemistry (changing A and B) – which affects the dynamic tilts of BO6 octahedra. Combining these insights gained from atomistic simulations has led to a compound being engineered that displays record uniaxial NTE within a Ruddlesden–Popper oxide due to this mechanism.

Solvent effects on an SNAr reaction; mechanism, kinetics, solvent design
Creators: name: Grant, Eliana Harriet
Publisher: name: Imperial College London
Year: 2019

description: This work provides a detailed study of an example SNAr reaction as these transformations are widely used in the synthesis of pharmaceutical drugs. The specific reaction we are considering is that of 2,4-difluoroacetophenone and pyrrolidine which has not previously been reported in the literature. We focus on elucidating the effect of solvent on the reaction mechanism and kinetics with a subsequent solvent design study to optimise both the reaction rate constant and selectivity. The solvent effect on the mechanism of the competing ortho- and para-substitution pathways is investigated using 1H NMR spectroscopy and density functional theory calculations. The reaction rate constants for the two reaction pathways are then determined by measuring reaction component concentrations in a set of diverse solvents using in situ 1H NMR spectroscopy followed by parameter estimation to extract the reaction rate constants. A hybrid empirical computer-aided methodology to design optimal solvents for the ortho-substitution reaction, incorporating both selectivity and reaction rate constant, is then presented. A surrogate model is built in which the reaction kinetics are correlated with a selection of solvent properties via linear regression. The surrogate model is then employed in a computer-aided molecular design formulation using multi-objective optimisation to identify solvents with improved performance compared with the initial solvent set. Safety, environmental impact and toxicity constraints are introduced which gives the possibility of designing solvents that simultaneously optimise the performance of the reaction whilst keeping in line with industrial guidelines. A set of Pareto-optimal solutions is obtained, highlighting the trade-off between reaction rate constant and selectivity.

description: In this paper, we propose a tree-based method called Multivariate RE-EM tree, which combines the regression tree and the linear mixed effects model for modeling multivariate response longitudinal or clustered data. The Multivariate RE-EM tree method estimates a population-level single tree structure that is driven by the multiple responses simultaneously and object-level random effects for each response variable, where correlation between the response variables and between the associated random effects are each allowed. Through simulation studies, we verify the advantage of the Multivariate RE-EM tree over the use of multiple univariate RE-EM trees and the Multivariate Regression Tree. We apply the Multivariate RE-EM tree to analyze a real data set that contains multidimensional nonfinancial characteristics of poverty of different countries as responses, and various potential causes of poverty as predictors.

description: Zero-point quantum fluctuations of a Néel order can produce effective interactions between quasi-orphan spins weakly coupled to the lattice. On the √3×√3-distorted triangular lattice, this phenomenon leads to a correlated partially disordered phase. In this article, we use matrix product state methods to study a similar model: the S=1/2 stuffed square lattice. Tuning the exchange amplitudes we go from a square lattice plus orphan central spins at J′/J=0, to the union jack lattice at J′/J=1, and a square lattice including all spins at J/J′=0. We calculate the complete antiferromagnetic phase diagram, dominated by ferrimagnetic and Néel orders, and compare it with existing results. Most importantly, we find a partially disordered phase in the weakly frustrated regime. In this phase, the Néel order from the square lattice is unaffected, while the central spins form a collective state with exponentially decaying double-striped correlations. We also study the role of quantum fluctuations by introducing an ordering staggered magnetic field on the square sublattice and find that the central spins order ferromagnetically when fluctuations from the Néel order are suppressed.

description: We investigate the far-infrared properties of galaxies selected via deep, narrow-band imaging of the H$α$ emission line in four redshift slices from $z=0.40$--$2.23$ over $\sim 1$deg$^2$ as part of the High-redshift Emission Line Survey (HiZELS). We use a stacking approach in the Herschel PACS/SPIRE bands, along with $850\,μ$m imaging from SCUBA-2 to study the evolution of the dust properties of H$α$-emitters selected above an evolving characteristic luminosity threshold, $0.2L^\star_{{\rm H}α}(z)$. We investigate the relationship between the dust temperatures and the far-infrared luminosities of our stacked samples, finding that H$α$-selection identifies cold, low-$L_{\rm IR}$ galaxies ($T_{\rm dust}\sim 14$k; $\log[L_{\rm IR}/{\rm L}_\odot]\sim 9.9$) at $z=0.40$, and more luminous, warmer systems ($T_{\rm dust}\sim 34$k; $\log[L_{\rm IR}/{\rm L}_\odot]\sim 11.5$) at $z=2.23$. Using a modified greybody model, we estimate "characteristic sizes" for the dust-emitting regions of HiZELS galaxies of $\sim 0.5$kpc, nearly an order of magnitude smaller than their stellar continuum sizes, which may provide indirect evidence of clumpy ISM structure. Lastly, we measure the dust masses from our far-IR SEDs along with metallicity-dependent gas-to-dust ratios ($δ_{\rm GDR}$) to measure typical molecular gas masses of $\sim 10^{10}$M$_\odot$ for these bright H$α$-emitters. The gas depletion timescales are shorter than the Hubble time at each redshift, suggesting probable replenishment of their gas reservoirs from the intergalactic medium. Based on the number density of H$α$-selected galaxies, we find that typical star-forming galaxies brighter than $0.2L^{\star}_{{\rm H}α}(z)$ host a significant fraction ($35\pm10$%) of the total gas content of the Universe, consistent with the predictions of the latest cosmological simulations.

title: Changing carbonate budgets and the maintenance of coral reefs and reef islands
Creators: name:  Perry,  Chris T
Publisher: name: Deutsche Geologische Gesellschaft - Geologische Vereinigung e.V. (DGGV)
Year: 2021

description: The ecology and structure of many tropical coral reefs have altered markedly over the past few decades. Drivers of this degradation range from direct local damage from destructive human practices to global scale climate stressors, and especially those associated with elevated sea‐surface temperature anomalies. A major consequence of these climatic and pervasive local stressors has often been a rapid decrease in the abundance of habitat building corals, which has consequently reduced reef structural complexity and coral carbonate production rates. Equally, many reefs have been impacted by changes (both increases and decreases) in the abundance of bioeroding taxa such as parrotfish, urchins, sponges and microendolithic organisms. The collective effect has been to alter the rates and relative balance of carbonate producing and eroding processes on many reefs. Such changes are of increasing interest because these processes directly regulate net rates of reef carbonate production and sediment generation, and collectively can impact upon multiple geo‐ecological functions on reefs. These functions include reef‐building and the capacity of reefs to accrete vertically in response to sea‐level rise, and the supply of sands necessary to sustain beaches and reef islands. This talk will discuss recent progress in developing methodologies to estimate rates of reef carbonate production, reef growth and sediment generation. It will then use selected recent field examples to highlight changes in these processes in response to ecological disturbance, and highlight the potential to integrate these data into numerical and lab-based modelling approaches than be used to predict coastal wave exposure under future sea level rise scenarios.

description: High-dimensional chaotic dynamical systems can exhibit strongly transient features. These are often associated with instabilities that have finite-time duration. Because of the finite-time character of these transient events, their detection through infinite-time methods, e.g. long term averages, Lyapunov exponents or information about the statistical steady-state, is not possible. Here we utilize a recently developed framework, the Optimally Time-Dependent (OTD) modes, to extract a time-dependent subspace that spans the modes associated with transient features associated with finite-time instabilities. As the main result, we prove that the OTD modes, under appropriate conditions, converge exponentially fast to the eigendirections of the Cauchy--Green tensor associated with the most intense finite-time instabilities. Based on this observation, we develop a reduced-order method for the computation of finite-time Lyapunov exponents (FTLE) and vectors. In high-dimensional systems, the computational cost of the reduced-order method is orders of magnitude lower than the full FTLE computation. We demonstrate the validity of the theoretical findings on two numerical examples.

description: We investigate the ground state and critical temperature (Tc) phase diagrams of the classical and quantum S=12 pyrochlore lattice with nearest-neighbor Heisenberg and Dzyaloshinskii-Moriya interactions (DMI). We consider ferromagnetic and antiferromagnetic Heisenberg exchange interaction as well as direct and indirect DMI. At the classical level, three ground states are found: all-in/all-out, ferromagnetic, and a locally ordered XY phase, known as Γ5, which displays an accidental classical U(1) degeneracy at the mean-field level. Quantum zero-point energy fluctuations computed to order 1/S are found to lift the classical ground-state degeneracy and select the so-called ψ3 state out of the degenerate manifold in most parts of the Γ5 regime. Likewise, thermal fluctuations treated classically at the Gaussian level entropically select the ψ3 state at T=0+. In contrast to this low-temperature state-selection behavior, classical Monte Carlo simulations find that the system orders at Tc in the noncoplanar ψ2 state of Γ5 for antiferromagnetic Heisenberg exchange and indirect DMI with a transition from ψ2 to ψ3 at a temperature TΓ5

description: BackgroundIn the Indian Ocean, the use of mosquito trawl nets has much developed onseagrass beds that provide appropriate, easily accessible areas for that gear type. Inthe bay of Toliara (Southwestern Madagascar), harboring one of the major Malagasycoral reef fisheries, the number of mosquito trawl nets has burst over the pastdecade, which has led to intense exploitation of seagrass fish and invertebratecommunities.MethodThis study aimed to characterize the abundance and diversity of macroinvertebratesin seagrass beds by analyzing the spatial and temporal patterns of mosquito trawlnet catches in the bay of Toliara. Monthly catches of 12 fishers were monitored for 7months in 2018-2019. The taxonomic richness, diversity, biomass and size structureof invertebrate community were assessed in relation to the nature and compositionof the seagrass habitats.ResultsOverall, 40 taxa of macroinvertebrates were observed in catches, mainly crabs(mainly Portunidae) associated with shrimps (mainly Processidae, Hippolytidae, andPalaemonidae) and Cephalopods (Octopodidae and Loliginidae). The crabcommunity was dominated by the genus Thalamita (two species) which representedthe large part of catches both in total abundance (67%) and biomass (70%).Macroinvertebrates constituted the by-catch of mosquito trawl nets, which mainlytargeted juvenile reef fishes. Invertebrate by-catch yielded from 1 to 72 % of thefishers’ income and was used for animal feed (93,9 %) and human consumption(6,1%).ConclusionOur results suggest that mosquito trawl nets have strong ecosystem effects onseagrass-associated macroinvertebrate community while sustaining the livelihood of> 100 households, which makes management of the fishery difficult. Implementinggear restrictions would involve building social capacity within the coastalcommunities while improving knowledge on the negative effects of the use ofmosquito trawl nets and other gears (i.e., gillnet, beach seine) in the fishery.

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.

description: The current study examines the challenges and constraints faced by rural, small-herd, llama (Lama glama) agropastoralists of the Bolivian Altiplano. Three different study sites with various degrees of agropastoralism were examined in order to describe the relationship between quinoa (Chenopodium quinoa) and llama production and the implications of land use competition between these two livelihoods. In order to document the impact of land use change, the study also examined the native forage species available to free grazing llamas and their relative importance. Llama pastoralists were interviewed and completed a survey on the perceived importance of native forage plants in grazing llama diets as well as the perceived constraints to llama husbandry. The relative frequency of citation (RFC) index was employed as a measure of relative importance of different native forage plant species. This data was supplemented with further primary data collected from the field using mixed methods involving participatory rural appraisal techniques (PRA), interviews and focus groups. Secondary data was collected from an in-depth literature review, government offices and other relevant institutions. The study presents a detailed list of all cited native forage species and their perceived importance as a forage crop and any ethnoveterinary uses. The results reveal that challenges and constraints can often be site-specific, and a lack of forage throughout the dry season (May to November) was a general constraint among study sites. Quinoa production was found to be in direct competition with llama husbandry, with many sites demonstrating s shift away from llama pastoralism.

description: We investigate classical Heisenberg models on the distorted windmill lattice and discuss their applicability to the spin-1/2 spin liquid candidate PbCuTe2O6. We first consider a general Heisenberg model on this lattice with antiferromagnetic interactions Jn (n=1,2,3,4) up to fourth neighbors. Setting J1=J2 (as approximately realized in PbCuTe2O6) we map out the classical ground-state phase diagram in the remaining parameter space and identify a competition between J3 and J4 that opens up interesting magnetic scenarios. Particularly, these couplings tune the ground states from coplanar commensurate or non-coplanar incommensurate magnetically ordered states to highly degenerate ground-state manifolds with subextensive or extensive degeneracies. In the latter case, we uncover an unusual classical spin liquid defined on a lattice of corner-sharing octahedra. We then focus on the particular set of interaction parameters Jn that has previously been proposed for PbCuTe2O6 and investigate the system's incommensurate magnetic ground-state order and finite-temperature multistage ordering mechanism. We perform extensive finite-temperature simulations of the system's dynamical spin structure factor and compare it with published neutron scattering data for PbCuTe2O6 at low temperatures. Our results demonstrate that thermal fluctuations in the classical model can largely explain the signal distribution in the measured spin structure factor but we also identify distinct differences. Our investigations make use of a variety of different analytical and numerical approaches for classical spin systems, such as Luttinger-Tisza, classical Monte Carlo, iterative minimization, and molecular dynamics simulations.

description: The influence of electric felds and currents has been investigated in the high-$T_c$ superconductors $YBaCuO$ and $BiSrCaCuO$ using a point-contact geometry with $Ag$ as the counterelectrode, which reveal switching transitions between states of a different resistance. The origin of this effect in point contacts is associated with electromigration of the oxygen, driven by the electric feld as well as by the currentinduced "electron wind". The switching effect preserves its basic features at elevated temperatures up to room temperature and in high magnetic felds up to 10 T.

Engineered ferritin nanocages for use in single molecule biosensors

description: Within modern healthcare personalised medicine is an important goal. A huge part of this goal is the early detection of disease, providing personalised treatment and eradication through targeted therapies. Single molecule detection offers the possibility to uncover rare hidden events from bulk populations, promising early detection of disease. Biosensors using nanopores or nanowells are an example of this. Whilst highly sensitive, they are often large in comparison to the analyte of interest and require additives to attract the particle to the nanopore. This thesis explored the creation of a nanowell based lab-on-chip device for the early detection of cancer, enabling personalised targeted treatment. Initially this was focused on cholangiocarcinoma (CCA), liver cancer of the bile ducts. To attract the CCA cells into the wells a novel engineered ferritin nanocage would be used. The high adaptability of ferritin proteins and self-assembly of the 24 subunit nanocage in maxi ferritins, make them an attractive targeting scaffold within bio-nanotechnology. Due to instability of the original bacterioferritin nanocage, this thesis describes the development of a stable fluorescent engineered ferritin nanocage through three alternative routes. Chemical labelling and fusing ferritin with Green Fluorescent Protein alone proved unsuccessful. Combining a smaller fluorophore, Improved Light, Oxygen or Voltage domain of the blue light receptor phototropin (iLOV), produced a stable iLOV bacterioferritin protein and Au-nanocage complex. Single molecule studies on the engineered ferritin nanocages showed high polydispersity within the solutions, temporarily improved upon filtration. Transition Electron Microscopy provided the only experimental evidence that gold encapsulated nanocages were formed with the iLOV bacterioferritin Au-nanocage complex. Early proof-of-concept antibody studies demonstrated the potential of using engineered ferritin nanocages in a single molecule biosensor. It is hoped that other researchers can expand on this work, using the novel stable iLOV bacterioferritin Au-nanocage complex for complete integration into a nanowell based lab-on-chip device, for the early detection of cancer.

description: A series of Ni0.6-x/2Zn0.4-x/2SnxFe2O4 (x = 0.0, 0.05, 0.1, 0.15, 0.2 and 0.3) (NZSFO) ferrite composites have been synthesized from nano powders using standard solid state reaction technique. The spinel cubic structure of the investigated samples has been observed by the X-ray diffraction (XRD). The magnetic properties such as saturation magnetization (Ms), remanent magnetization (Mr), coercive field (Hc) and Bohr magneton (B) are calculated from the hysteresis loops. The value of Ms is found to decrease with increasing Sn content in the samples. This change has been successfully explained by the variation of A-B interaction strength due to Sn substitution in different sites. The compositional stability and quality of the prepared ferrite composites have also been endorsed by the fairly constant initial permeability (/) over a wide range of frequency region. The decreasing trend of / with increasing Sn content has been observed. Curie temperature (TC) has found to increase with the increase in Sn content. Wide spread frequency utility zone indicates that the NZSFO can be considered as a good candidate for use in broadband pulse transformer and wide band read-write heads for video recording. The abnormal behavior for x = 0.05 has been explained with existing theory.

description: In highly out-of-equilibrium states of matter, such as those induced by a pump laser, the applicability of well-established spectroscopic probes of magnetic order are called into question. Here we address the validity of x-ray absorption techniques in pump laser conditions, focusing on magnetic linear dichroism (MLD), a crucial probe of antiferromagnetic (AFM) order. We directly compute the dynamics of the square of the spin moment and compare the results to those obtained via the MLD response. For AFM FePd the agreement between these distinct routes to the magnetic moment severely degrades at pulse fluences greater than ∼1mJ/cm2, indicating a breakdown of the MLD response as an accurate probe of the transient moment. This contrasts with the MLD for ferromagnetic FePt, which reliably tracks the moment for fluences (and absorbed energies) up to an order of magnitude greater than the breakdown threshold for AFM FePd. We find the underlying microscopic reason for this to be increased laser induced excitations out of the d band in AFM FePd, where this increase is made possible by the AFM pseudogap.
