PET studies on disease progression and treatment efficacy in Alzheimer’s disease and mild cognitive impairment
Creators: name: Okello, Aren Atiti
Publisher: name: Imperial College London
Year: 2011

description: Alzheimer’s disease (AD) is the most common cause of dementia. Mild cognitive impairment (MCI) is a transitional state between normal ageing and dementia. Positron emission tomography (PET) can detect the metabolic and neuro-chemical changes that occur in MCI and dementia. The aim of this thesis was to assess the use of PET as an in vivo biomarker for early disease detection, prognosis, and proof of treatment efficacy in AD and MCI. In study I, the prevalence of increased beta-amyloid deposition (assessed by 11C-PIB PET) and microglial activation (assessed by 11C-PK11195 PET) was studied in amnestic MCI (aMCI) subjects. 50% had raised amyloid deposition and 38% evidence of microglial activation. Subjects with increased PIB retention had significantly higher cortical PK11195 binding. In study II, rates at which aMCI subjects with and without increased amyloid load converted to AD were compared over one to three years of follow-up. 55% of aMCI subjects had significantly increased PIB retention at baseline and 82% of these converted to AD compared to 7% of aMCI cases with normal PIB uptake. Faster AD converters had higher PIB retention than slower converters. In study III, changes in regional cerebral Aβ deposition (assessed with 11C-PIB PET) and regional cerebral glucose metabolism (rCMRGlc) (assessed with 18F-FDG PET) were followed over three years in MCI and AD subjects. The MCI subjects demonstrated small but significant increases in 11C-PIB retention and parallel decreases in rCMRGlc. 11C-PIB retention in AD subjects remained unchanged, despite decreases in rCMRGlc and a decline in their MMSE. In study IV, the effects of passive immunisation with infusions of the anti-Aβ monoclonal antibody bapineuzumab on amyloid plaque load was assessed in AD subjects. After 78 weeks, subjects receiving bapineuzumab had reduced cortical 11C-PIB retention compared with their baseline and with placebo treated subjects. Through its detection of fibrillar Aβ, PET can detect the presence of Alzheimer pathology and provides a prognostic indicator of future progression of MCI to AD. However, PIB PET is not a marker of AD progression as the amyloid load remains relatively stable. 18F-FDG PET, a marker of synaptic activity, more closely mirrors cognitive decline as neurodegeneration progresses. Finally, PET allows the changes in glial activation in MCI to be monitored and provides a rationale for therapeutic trials of anti-inflammatory agents.

description: In the mixed state of type II superconductors penetrated by an external magnetic field in the form of a lattice of Abrikosov vortices the dc resistance is known to increase with increasing velocity of the vortex lattice. Accordingly, vortex pinning sites impeding the vortex motion are widely used to preserve the low-dissipative response of the system. Here, while subjecting superconducting Nb films with nanogrooves to a combination of dc and ac current stimuli and tuning the number of mobile and pinned vortices by varying the magnetic field around the so-called matching values, we observe a completely opposite effect. Namely, the vortex-related microwave excess loss for mobile vortices becomes smaller than for pinned vortices in a certain range of power levels at ac current frequencies above 100\,MHz. While a theoretical description of the observed effect is yet to be elaborated we interpret our findings in terms of a competition of the effective cooling of the system by the quasiparticles leaving the vortex cores with the conventional Joule heating caused by the current flow.

Ab initio studies of defect concentrations and diffusion in metal oxides
Creators: name: Frensch, Kilian
Publisher: name: Imperial College London
Year: 2011

description: This work presents a methodology for determining the concentrations and diffusion coefficients of point defects in metal oxides using ab initio calculations of defect formation energies and diffusion barriers, and the binding energies of defect-impurity clusters. The methodology is applied to analyse the long-standing mysteries surrounding the mechanism of self-diffusion in α-Al2O3. Al2O3 is a prototypical large band gap ceramic with extensive applications, many of which depend on its defect chemistry. In particular, point defect concentrations, that vary with temperature and impurity doping, govern diffusion properties such as creep, sintering, or the oxidation rate of Al-containing alloys. Experimental measurements of the self-diffusion coefficients in bulk alumina reveal three important truths that theory cannot reconcile, collectively termed the ’corundum conundrum’. First, large experimental activation energies for oxygen and aluminum diffusion and low theoretical formation energies imply unreasonably high diffusion barriers of ∼ 5eV. Second, aluminum diffusion is orders of magnitude faster than oxygen diffusion. Third, the oxygen diffusion coefficient is relatively insensitive to aliovalent doping, increasing by a factor of 100 on heavy Mg2+-doping, and decreasing by a similar amount on Ti4+-doping. We attempt to resolve this conundrum by calculating the formation energies and binding energies of a raft of native point defects and defect-impurity clusters as functions of temperature T and oxygen partial pressure pO2 , and the diffusion barriers of the native defects, using density functional theory. We then use a thermodynamic mass action approach to determine the concentrations of the defects and clusters, and the diffusion coefficients of the defects, as functions of T, pO2 , and the concentrations of aliovalent dopants, [Mg2+] and [Ti4+]. In the process, we discover new ground-state defect structures for the aluminum vacancy and oxygen interstitial, and demonstrate that diffusion of aluminum vacancies and interstitials occurs by extended vacancy and interstitialcy mechanisms, and oxygen interstitials by a dumbbell interstitialcy mechanism, all of which yield much lower migration barriers than previous theory. Unfortunately, the results do not demonstrate the experimentally-found insensitivity of the oxygen diffusivity to aliovalent doping. This could be an artefact of approximations within density functional theory and our methodology, and we show that modest changes in the calculated binding energies lead to significant defect clustering. This defect clustering could result in a buffering mechanism that can explain the insensitivity of the diffusivity to aliovalent doping, and may occur in other ionic materials. More accurate calculations, employing hybrid functionals or quantum Monte Carlo methods, may be necessary to elucidate this effect, but are currently computationally intractable for our purposes.
Destabilisation of the medial meniscus: imaging and mechanics of a murine surgical osteoarthritis model
Creators: name: Moodie, Jonathan
Publisher: name: Imperial College London
Year: 2011

description: Destabilisation of the medial meniscus (DMM) is a murine surgical instability model of osteoarthritis (OA). In this thesis the bone and cartilage changes were examined at different time points and in different strains of mice in the DMM model. In the first study C57Bl/6 mice underwent DMM surgery and were culled four and eight weeks postoperatively. Tibiae were examined using confocal scanning laser microscopy (CSLM) for cartilage changes and micro-computed tomography (micro-CT) for bone changes. Additional mice underwent laxity testing. The tibia exhibited significant loss of cartilage and bone on the posterior plateau. A significant increase of anterior-posterior laxity suggested that damage of the anterior cruciate ligament had occurred during surgery, which permitted the femur to relocate to posterior tibia causing bone and cartilage damage. A second study investigated early stage bone changes in the DMM model. CSLM and micro-CT were used in conjunction with non-decalcified histology. Mice received calcein injections three and six days prior to sacrifice, and were culled two weeks after surgery. There was an increase of epiphyseal bone volume. No change in cartilage was observed with CSLM. A significant increase of mineralising surface/bone surface and osteoid surface/bone surface occurred at two weeks. A final study compared the bone response of two mice strains (BALB/c and C57Bl/6). Laxity was compared between strains eight weeks post operatively. Epiphyseal bone increased in both strains, more so in the BALB/c which had initially less epiphyseal bone volume. There was no change in histological mineralisation parameters or laxity measures. In this work multi-modal imaging techniques were developed to determine the change in bone and cartilage in the DMM model.

description: Although several studies show that Schinus terebinthifolius Raddi fruits are a promising source of bioactive compounds, few studies have investigated the anticancer activity of its essential oil (EO). The objective of this study was therefore to investigate the antiproliferative activity of S. terebinthifolius fruit EO against eight human tumor cell lines. A central composite rotatable design with 11 experiments was developed to investigate the optimal conditions of hydrodistillation by Clevenger apparatus. EO obtained at optimized conditions (yield greater than 6.7%) showed potent activity for all cell lines investigated; the most promising results were observed against leukemia, kidney, multidrug-resistant ovarian, and prostate tumor cell lines. Gas chromatography-mass spectrometry revealed the following major compounds in the EO: δ-3-carene (33.78–36.73%), α-phellandrene (15.67–17.30%), limonene (15.03–16.32%), α-pinene (7.03–9.20%), and germacrene D (4.98–6.99%). Future work involving fractionation of the EO might shed some light on the compounds responsible for each antiproliferative activity.

description: Calcium rich gap transients represent an intriguing new class of faint and fast evolving supernovae that exhibit strong [Ca II] emission in their nebular phase spectra. In this paper, we present the discovery and follow-up observations of iPTF 16hgs -- an intermediate luminosity and fast evolving transient that exhibited a double peaked light curve. Exhibiting a typical Type Ib spectrum in the photospheric phase and an early transition to a [Ca II] dominated nebular phase, we show that iPTF 16hgs shows properties consistent with the class of Ca-rich gap transients, with two interesting exceptions. First, while the second peak of the light curve is similar to other Ca-rich gap transients (suggesting $M_{ej}$ of 0.4 M$_\odot$ and peak luminosity of $3 \times 10^{41}$ ergs s$^{-1}$), we show that the first blue and fast declining (over $2$ days) peak is unique to this source. Second, with Integral Field Unit observations of the host galaxy, we find that iPTF 16hgs occurred in the outskirts (projected offset of $6$ kpc $ = 1.9 R_{eff}$) of a low metallicity (0.4 Z$_\odot$), star forming, dwarf spiral galaxy. Using deep late-time VLA and uGMRT observations, we place stringent limits on the local environment of the source, ruling out a large parameter space of circumstellar densities and mass loss environments of the progenitor. If iPTF 16hgs shares explosion physics with the class of Ca-rich gap transients, the presence of the first peak can be explained by enhanced mixing of 0.01 M$_\odot$ of $^{56}$Ni into the outer layers the ejecta, reminiscent of some models of He-shell detonations on WDs. On the other hand, if iPTF 16hgs is physically unrelated to the class, the first peak is consistent with shock cooling emission (of an envelope with a mass of 0.08 M$_\odot$ and radius of 13 R$_\odot$) associated with a core-collapse explosion of a highly stripped massive star in a close binary system.

Structural insights into host cell adhesion by Toxoplasma gondii MIC4
Creators: name: Cowper, Ben
Publisher: name: Imperial College London
Year: 2012

description: Toxoplasma gondii is a highly pervasive protozoan parasite, capable of infecting almost all mammals, including humans. Infection can have fatal consequences for immuno-suppressed individuals, whilst transmission to a developing fetus can induce a spontaneous abortion in pregnant females. T. gondii is perceived to be a model organism in the study of its phylum, Apicomplexa, which includes the Plasmodium species which cause malaria. Apicomplexans are obligate intracellular parasites, in which a strong host cell attachment is established through surface microneme proteins (MICs). Numerous MICs have been identified in T. gondii, many forming multi-adhesive complexes, such as TgMIC1/4/6, within which TgMIC4 is known to possess host cell binding activity within its C-terminal apple-5 & 6 (A56) domains. Prior to these studies, recombinant TgMIC4-A56 was produced yielding a partially-folded protein capable of binding to galactose. Herein the folded component has been identified as A5, and the solution structure of this domain has been solved via NMR spectroscopy. Carbohydrate microarray experiments have confirmed an ability to bind galactosyl-terminated oligosaccharides, whilst NMR and ITC experiments have enabled extensive characterisation of TgMIC4-A5 binding to a range of ligands. The domain binds particularly strongly to a pentasaccharide fragment from GM1 ganglioside; a potential in vivo receptor. Additionally, chemical shift perturbation data and intermolecular NOEs have been used to drive molecular docking of TgMIC4-A5 and lacto-N-biose (Galβ1→3GlcNac). The resulting structure suggests that the mechanism of galactose discrimination by TgMIC4-A5 is similar to that of other galactose-specific lectins. Combined with collaborating studies, this work aids our overall understanding of TgMIC4 function and encourages speculation as to the precise roles of the protein within T. gondii. In addition to a probable contributory role in the initial stages of host cell invasion, the protein may modulate events downstream of this process, through interactions with galactosylated receptors.

description: The remains of the original 190-mile Las Vegas and Tonopah historic railroad alignment begin north of Las Vegas and end in Goldfield. The rail service began in downtown Las Vegas. From that point, an approximate 20 miles have been removed or disturbed through urbanization. Of the remaining 170 miles, an 18.5-mile portion is managed by Nellis Air Force Base (NAFB). An inventory of this portion of the grade was conducted in 2009. The hardware was removed more than 90 years ago and a degree of off-road driving combined with flash floods has resulted in a lack of overall physical integrity. Archaeologists noted 19 wooden culverts had been constructed within the grade or berm on the NAFB-managed portion. This is the first portion in which wooden culverts have been comparatively evaluated.

description: We estimate a general mixture of Markov jump processes. The key novel feature
of the proposed mixture is that the transition intensity matrices of the Markov
processes comprising the mixture are entirely unconstrained. The Markov
processes are mixed with distributions that depend on the initial state of the
mixture process. The new mixture is estimated from its continuously observed
realizations using the EM algorithm, which provides the maximum likelihood (ML)
estimates of the mixture's parameters. We derive the asymptotic properties of
the ML estimators. To obtain estimated standard errors of the ML estimates of
the mixture's parameters, an explicit form of the observed Fisher information
matrix is derived. In its new form, the information matrix simplifies the
conditional expectation of outer product of the complete-data score function in
the Louis (1982) general matrix formula for the observed Fisher information
matrix. Simulation study verifies the estimates' accuracy and confirms the
consistency and asymptotic normality of the estimators. The developed methods
are applied to a medical dataset, for which the likelihood ratio test rejects
the constrained mixture in favor of the proposed unconstrained one. This
application exemplifies the usefulness of a new unconstrained mixture for
identification and characterization of homogeneous subpopulations in a
heterogeneous population.

description: We study partially massless gravity theory(PM gravity theory) and suggest an alternative way to add higher order interaction vertices to the theory. Rather than introducing self interaction vertices of the gravitational fields to the partially massless gravity action, we consider interactions with matter fields, since it is well known that addition of the self interaction terms necessarily breaks the $U(1)$ gauge symmetry that PM gravity theory enjoys. For the coupling with matter fields, we consider two different types of interaction vertices. The first one is given by an interaction Lagrangian density, $\mathcal L_{int}\sim h_{μν}T^{μν}$, where $h_{μν}$ is the PM gravity field and $T^{μν}$ is the stress-energy tensor of the matter fields. To retain the $U(1)$ gauge symmetry, the matter fields also transform accordingly and it turns out that the transform must be non-local in this case. The second type interaction is obtained by employing a gauge covariant derivative with the PM gravity field, where the PM gravity fields play a role of a gauge connection canceling the phase shift of the matter fields. We also study the actions and the equations of motion of the partially massless gravity fields. As expected, it shows 4 unitary degrees of freedom. 2 of them are traceless tensor modes and they are light like fields. The other 2 are transverse vector modes and their dispersion relation changes as background space time (de Sitter) evolutes. In the very early time, they are light like but in the very late time, their velocity become a half of speed of light. The vector mode dispersion relation shows momentum dependent behavior. In fact, the higher(lower) frequency modes show the faster(slower) velocity. We suggest their quantization, compute Hamiltonians to present their exited quanta and construct their free propagators.

description: We study the nonlocal regularization for the non-abelian gauge theories for an arbitrary value of the gauge parameter (ξ). We show that the procedure for the nonlocalization of field theories established earlier by the original authors, when applied in that form to the Faddeev-Popov effective action in a linear gauge cannot lead to a (ξ)-independent result for the observables. We then show that an alternate procedure which is simpler can be used and that it leads to the S-matrix elements (where they exist) independent of (ξ).

description: Joel Smith begins this 1971 interview by outlining his personal and professional background. La Brie proceeds to ask about the differences between black and white newspapers. Smith discusses the successes and failures of the black press over time and about its future prospects. La Brie asks how the black press has changed and about its sensationalist reputation. Smith explains how he relies on diverse news sources to understand current events and the black press' unique ability to interpret them. The conversation turns to a comparison between the black and establishment press. La Brie asks how the United States would be different without the black press and about its changing social role. They discuss why there are relatively few black newspapers. La Brie asks about the need for a national black news service and what section is, in his view, the most important. The interview concludes with a discussion of whether the mainstream press has become more representative in its coverage of minority affairs.

Method of model reduction and multifidelity models for solute transport in random layered porous media

description: This work presents a hierarchical model for solute transport in bounded layered porous media with random permeability. The model generalizes the Taylor-Aris dispersion theory to stochastic transport in random layered porous media with a known velocity covariance function. In the hierarchical model, we represent (random) concentration in terms of its cross-sectional average and a variation function. We derive a one-dimensional stochastic advection-dispersion-type equation for the average concentration and a stochastic Poisson equation for the variation function, as well as expressions for the effective velocity and dispersion coefficient. We observe that velocity fluctuations enhance dispersion in a non-monotonic fashion: the dispersion initially increases with correlation length λ, reaches a maximum, and decreases to zero at infinity. Maximum enhancement can be obtained at the correlation length about 0.25 the size of the porous media perpendicular to flow.

description: The epithelial mesenchymal transition (EMT) is one step in the process through which carcinoma cells metastasize by gaining the cellular mobility associated with mesenchymal cells. This work examines the dual influence of the TGF-β pathway and intercellular contact on the activation of EMT in colon (SW480) and breast (MCF7) carcinoma cells. While the SW480 population revealed an intermediate state between the epithelial and mesenchymal states, the MC7 cells exhibited highly adhesive behavior. However, for both cell lines, an exogenous TGF-β signal and a reduction in cellular confluence can push a subgroup of the population towards the mesenchymal phenotype. Together, these results highlight that, while EMT is induced by the synergy of multiple signals, this activation varies across cell types.

description: `Umbral calculus' deals with representations of the canonical commutation relations. We present a short exposition of it and discuss how this calculus can be used to discretize continuum models and to construct representations of Lie algebras on a lattice. Related ideas appeared in recent publications and we show that the examples treated there are special cases of umbral calculus. This observation then suggests various generalizations of these examples. A special umbral representation of the canonical commutation relations given in terms of the position and momentum operator on a lattice is investigated in detail.

description: L’identité de genre est un des aspects fondamentaux de l’identité personnelle, spécialement chez les individus LGBT+ (Bereni et al., 2020).
Dans le but de mieux saisir les besoins et attentes de la communauté LGBT+, que l’on peut considérer comme une minorité par rapport aux personnes cisgenres hétérosexuelles (Gündemir et al., 2019), nous mènerons ce programme de recherche afin de déterminer quelle idéologie genrée les personnes LGBT+ préfèrent voir adoptée et quel est l’impact en termes d’égalité entre groupes de genre de ces idéologies genrées.
On recense principalement deux idéologies genrées qui ont pour but commun, mais par des voies distinctes, de favoriser l’égalité entre les différentes identités de genres et l’épanouissement de chacun : l’idéologie « genderaware » (GA) (attention aux différences de genre), qui valorise la diversité des genres et considère qu’il faut prendre en compte les appartenances groupales de genre des individus (Hahn et al., 2015), l’idéologie « genderblind » (GB) (cécité aux différences de genre), qui considère, au contraire, qu’il faut ignorer les appartenances de genre et traiter les personnes en tant qu’individus (Koenig & Richeson, 2010). L’idéologie la plus plébiscitée, correspondant aux besoins fondamentaux de cette minorité (Dovidio et al., 2007), leur permettrait de ressentir plus de confort et davantage de confiance (Purdie-Vaughns et al., 2008). Dès lors, il s’agira de comprendre quelle idéologie genrée, et pourquoi, les personnes LGBT+ préféreront voir adoptée par la société française, quelles sont les conséquences sur leur situation des deux idéologies genrées, et si cela varie selon le contexte dans lequel ces idéologies peuvent servir de cadre de référence (citoyenneté, travail, amis, intimité).
Non-parametric decompositions of disk galaxies in S${^4}$G using DiskFit

description: We present photometric models of 532 disk galaxies in 3.6μm images from the Spitzer Survey of Stellar Structure in Galaxies (S$^4$G) using the non-parametric DiskFit algorithm. We first test DiskFit's performance on 400 synthetic S$^4$G-like galaxy images. DiskFit is unreliable in the bulge region, but accurately disentangles exponential disks from Ferrers bars farther out as long as their position angles differ by more than 5${^\circ}$. We then proceed to model the S$^4$G galaxies, successfully fitting 489 of them using an automated approach for initializing DiskFit, optimizing the model and deriving uncertainties using a bootstrap-resampling technique. The resulting component geometries and surface brightness profiles are compared to those derived by Salo et al. (2015) using the parametric model galfit. We find generally good agreement between the models, but discrepancies between best-fitting values for individual systems are often significant: the choice of algorithm clearly impacts the inferred disk and bar structure. In particular, we find that DiskFit typically assigns more light to the bar and less light to the disk relative to the Ferrers and exponential profiles presented by Salo et al. (2015) in the bar region. Given DiskFit's reliability at disentangling these components in our synthetic images, we conclude that the surface brightness distributions of barred S$^4$G galaxies are not well-represented by these functional forms. The results presented here underscore the importance of validating photometric decomposition algorithms before applying them to real data and the utility of DiskFit's non-parametric approach at measuring the structure of disks and bars in nearby galaxies.

Business models: An empirical approach to firm structures and organisational change
Creators: name: Bock, Adam J.
Publisher: name: Imperial College London
Year: 2010

description: Popular though poorly-defined, the business model construct has generated a fragmented and non-accretive research literature. Despite prominence in the practice community for scholarly research has yet to converge on construct boundaries or establish a research framework in organizational theory. This study develops an integrative approach to business models and identifies business model formation and change processes. Prior studies address business models within the strategy discourse of competitive positioning. The failure to disentangle business models and strategy has limited theoretical and practical research. A quasi-systematic review of the academic literature combined with a discourse analysis of the business model in practice yields an empirical assessment of business model language. Managers use business models to address opportunities rather than position the firm for competitive advantage. This anchors an integrative definition for the business model as the design of organizational structures to enact an opportunity. Building on this framework, an analysis of structured interviews with 556 large firm CEOs establishes the links between organizational structures and strategic flexibility. Working within a capabilities and structural framework, the study extends research on strategic flexibility firms engaged in business model innovation in a global, cross-industry context. Creative culture enables strategic flexibility while partner dependence inhibits it. In addition, firms that focus managerial attention without giving up non-core activities achieve flexible outcomes. Finally, a case-based study of innovative entrepreneurial firms unpacks characteristics of business model formation and change processes. In contrast to theories of outward-facing strategic fit with environment, entrepreneurial firms undergo an internallydriven process towards business model coherence. The case studies reveal a self-evolving narrative process operating at multiple levels within the firm. The application of a narrative framework facilitates a novel sense-making approach to theories of change at entrepreneurial firms.
