Computational analysis of hemodynamics and thrombosis in aortic dissection for clinical applications
Creators: name: Armour, Chloe Harriet
Publisher: name: Imperial College London
Year: 2021

description: Type B aortic dissection is a potentially devastating disease of the aorta initiated by a tear in the inner lining of the aortic wall. Blood flow through this tear causes the aortic wall layers to separate and a secondary channel of blood flow know as the ‘false lumen’ forms. Complete thrombosis (clotting) of the false lumen, is the desired outcome of either medical or endovascular (TEVAR) treatment. However, it is currently unclear at the time of diagnosis how a specific dissection will progress with either treatment option. Anatomical studies have identified a range of morphological factors that may be influential in disease progression, though no single parameter has been found to be independently predictive of patient prognosis. Computational fluid dynamics (CFD) studies have aimed to assess the hemodynamic state of dissection, however, studies have generally been limited due to simplified geometries and unphysiological boundary conditions due to the lack of patient-specific in vivo flow data. Thanks to recent developments in imaging technologies, in vivo flow data can now be acquired through 4D-flow magnetic resonance imaging (MRI), though detailed evaluation of dissection flow fields is limited due to poor image quality. CFD has the potential to be a useful tool in clinical practice for predicting disease progression, as long as the results are physiological to specific patients. 4D-flow MRI data could provide the patient-specific details required to build detailed and accurate CFD models. The primary objective of this thesis is to develop clinically applicable computational models to accurately simulate hemodynamics and thrombus formation in type B dissection patients. A 4D-flow MRI based CFD workflow was developed and key model inputs were assessed in detail. The use of a patient-specific 3D inlet velocity profile was compared to commonly used idealised profiles, with the 3D profile producing results which agreed best with in vivo data. The importance of major and minor aortic branches in geometry segmentation was assessed, and results showed that exclusion of such branches can significantly impact predicted hemodynamics and thrombus formation. The finalised CFD workflow was evaluated against in vivo data and was shown to be able to faithfully reproduce dissection hemodynamics in a study of 5 patients. A hemodynamics-based thrombus predicting model was evaluated and simplified in order to improve computational efficiency for clinical application. Finally, the CFD workflow and thrombus model were utilised in studies on the influence of re-entry tears both pre- and post-TEVAR.

description: After developing the basic theory of locally cartesian localizations of presentable locally cartesian closed infinity-categories, we establish the representability of equivalences and show that univalent families, in the sense of Voevodsky, form a poset isomorphic to the poset of bounded local classes, in the sense of Lurie. It follows that every infinity-topos has a hierarchy of "universal" univalent families, indexed by regular cardinals, and that n-topoi have univalent families classifying (n-2)-truncated maps. We show that univalent families are preserved (and detected) by right adjoints to locally cartesian localizations, and use this to exhibit certain canonical univalent families in infinity-quasitopoi (certain infinity-categories of "separated presheaves", introduced here). We also exhibit some more exotic examples of univalent families, illustrating that a univalent family in an n-topos need not be (n-2)-truncated, as well as some univalent families in the Morel--Voevodsky infinity-category of motivic spaces, an instance of a locally cartesian closed infinity-category which is not an n-topos for any $0\leq n\leq\infty$. Lastly, we show that any presentable locally cartesian closed infinity-category is modeled by a combinatorial type-theoretic model category, and conversely that the infinity-category underlying a combinatorial type-theoretic model category is presentable and locally cartesian closed. Under this correspondence, univalent families in presentable locally cartesian closed infinity-categories correspond to univalent fibrations in combinatorial type-theoretic model categories.

Towards engineering microbial consortia using RNA-based genetic controllers
Creators: name: Boo, Alice
Publisher: name: Imperial College London
Year: 2022

description: In nature, quorum sensing is a mechanism used by microbes to communicate and coordinate behaviours at the population level. Over the last two decades, synthetic biologists have used the unique property of quorum sensing to sense population density for coordinating cellular behaviours of single and mixed cultures. This gave rise to the development of multicellular biosynthesis systems for metabolic engineering and of spatially distributed systems for synthetic biology. However, robustly controlling the composition of multicellular systems remains a challenge and limits its wide adoption by the metabolic engineering community. Current strategies for controlling synthetic microbial communities vastly rely on engineer- ing metabolic dependencies between microbial species in a process called syntrophy. While syntrophy guarantees the survival of all strains in the coculture, it does not provide a way to control community composition. Existing genetic circuits that can dynamically control community composition often impose too much burden on their hosts for division of labour to be a viable solution to improve yields and titers of valuable metabolic products. Here we investigate the potential of using RNA-based gene circuits to reduce the cost of express- ing heterologous genes for the control of community composition in a two-member E. coli coculture. In this work, we present the development of three genetic modules that rely on RNA species to detect changes in population density and to regulate growth rate when community composition becomes unstable. Together, the modules work in concert to stabilise community composition around a ratio set by the intrinsic properties of the circuit’s genetic components. We identify the key parameters of the circuits that enable tuning of the composition ratio. We characterise the cost of expressing each module of the genetic controller by measuring its impact on the host growth rate and on consumption of free cellular resources. Together these findings highlight the importance of developing host-aware circuits to control community composition so as to enable their wide adoption by metabolic engineers.
Is composite noise necessary for sudden death of entanglement?

description: The finite time disentanglement or entanglement sudden death, when only one part of the composite system is subjected to a single noise, is examined. While it is shown that entanglement sudden death can occur when a part of the entangled mixed state is subjected to either amplitude noise or phase noise, local action of either of them does not cause entanglement sudden death in pure entangled states. In contrast, depolarizing noise is shown to have an abilitiy to cause sudden death of entanglement even in pure entangled states, when only one part of the state is exposed to it. The result is illustrated through the action of different noisy environments individually on a single qubit of the so-called X class of states and an arbitrary two-qubit pure state.

Identifying novel therapeutic strategies for brain metastatic and mucosal melanoma

Publisher: name: Imperial College London
Year: 2021

description: Melanoma encompasses a number of malignancies all originating from cells of melanocytic origin. Generally speaking, melanoma has a promising prognosis with a five-year survival rate of 91.3%, however two subtypes in particular – melanoma brain metastasis (MBM) and mucosal melanoma (MM) – have a high mortality and limited therapeutic options. Cancerous cells frequently have altered metabolic pathways in order to sustain their rapid growth. Cutaneous melanoma has previously been shown to be both arginine dependent and arginine auxotrophic due to silencing of the enzyme argininosuccinate synthase 1 (ASS1), which catalyses de novo arginine synthesis. As a result, arginine deprivation has demonstrated efficacy in the treatment of melanoma, however to date MBM have been excluded from trials. I hypothesised that MBM will be particularly sensitive to arginine deprivation due to it’s observed increased dependency on arginine metabolism and oxidative phosphorylation compared to primary cutaneous melanoma. Results show ASS1 is repressed in both MBM and extracranial melanoma metastasis (EMM), but that this is reversible in some cell lines upon arginine starvation with ADI-PEG20. Regardless of ASS1 upregulation, MBM and EMM were found to be sensitive to ADI-PEG20 via mitochondrial fragmentation followed by apoptotic cell death. The induction of autophagy and epigenetic remodeling of glutamate related pathways constitute two potential resistance mechanisms which were identified. MM is a rare and understudied cancer with very little known about it’s pathogenesis. Investigation of the mutational profile and immunology of disease was hypothesised to identify potentially novel therapeutic targets. Results show oncogeneic pathways similar to those activated in cutaneous melanoma are mutated in MM, however novel pathways unique to MM were also identified. All significantly mutated pathways were associated with MAPK signalling, PI3K/AKT signalling, and the Warburg effect, suggesting these to be potentially important therapeutic targets. Tumours were heavily infiltrated with immune cells in a site specific manner, with gastric and urogenetial tumours displaying infiltration of an anti-tumour immune population, and nasal tumours displaying mixed pro- and anti-tumour infiltration alongside epithelial-to-mesenchymal transition (EMT). Taken together, this study identifies suitable therapies and therapeutic targets for hard-to-treat MBM and MM.
One-dimensional model of inertial pumping

description: A one-dimensional model of inertial pumping is introduced and solved. The pump is driven by a high-pressure vapor bubble generated by a microheater positioned asymmetrically in a microchannel. The bubble is approximated as a short-term impulse delivered to the two fluidic columns inside the channel. Fluid dynamics is described by a Newton-like equation with a variable mass, but without the mass derivative term. Because of smaller inertia, the short column refills the channel faster and accumulates a larger mechanical momentum. After bubble collapse the total fluid momentum is nonzero, resulting in a net flow. Two different versions of the model are analyzed in detail, analytically and numerically. In the symmetrical model, the pressure at the channel-reservoir connection plane is assumed constant, whereas in the asymmetrical model it is reduced by a Bernoulli term. For low and intermediate vapor bubble pressures, both models predict the existence of an optimal microheater location. The predicted net flow in the asymmetrical model is smaller by a factor of about 2. For unphysically large vapor pressures, the asymmetrical model predicts saturation of the effect, while in the symmetrical model net flow increases indefinitely. Pumping is reduced by nonzero viscosity, but to a different degree depending on the microheater location.

Reconstructing flow from thermal wall imprint
Creators: name: Hossain, Md Rakib
Publisher: name: Imperial College London
Year: 2021

description: This thesis develops data-driven flow reconstruction methods to reconstruct the velocity of plane Couette flow from wall temperature. We performed a Direct Numerical Simulation (DNS) for a heated plane Couette flow with imposed flux boundary condition at the bottom wall to create a data-set. Due to the the imposed flux the temperature at bottom wall is free and wall temperature patterns can develop. The focus of this thesis is on the investigations of the strong correlation between the flow velocity and the wall temperature. We analyse their joint probability density function and cross variance spectrum to develop a spectral linear regression model. This model successfully reconstructs wall shear stress from wall temperature except possibly at peaks. To reconstruct flow velocity from wall temperature, we apply flow decomposition modes such as the Proper Orthogonal Decomposition (POD) modes \cite{Holmes2012ProperDecomposition}. We design test problems to develop a framework to reconstruct \emph{gappy} fields with missing information. In this framework, we prescribe suitable regularisation for the under-determined \emph{gappy} fields. We also develop a decomposition method - the subdomain POD method which divides a physical domain into a number of subdomains and then applies the POD method in each subdomain individually. This subdomain POD are locally optimised and inherits properties of the POD modes. In both cases, namely the POD and the subdomain POD method, the reconstructions are found to be in good agreement with the flow velocity obtained form the DNS. To develop data-driven methods with imposed physical constraints, we propose a linear dynamical model based on Orr-Sommerfeld-Squire \cite{Kim2007,Murray2006} system and the scalar transport equation. This model successfully reconstruct some of the key flow structures at $z^+=35$.

description: Transparent electronic materials are increasingly in demand for a variety of optoelectronic applications. BaSnO3 is a semiconducting oxide with a large band gap of more than 3.1 eV. Recently, we discovered that La doped BaSnO3 exhibits unusually high electrical mobility of 320 cm^2(Vs)^-1 at room temperature and superior thermal stability at high temperatures [H. J. Kim et al. Appl. Phys. Express. 5, 061102 (2012)]. Following that work, we report various physical properties of (Ba,La)SnO3 single crystals and films including temperature-dependent transport and phonon properties, optical properties and first-principles calculations. We find that almost doping-independent mobility of 200-300 cm^2(Vs)^-1 is realized in the single crystals in a broad doping range from 1.0x10^19 to 4.0x10^20 cm^-3. Moreover, the conductivity of ~10^4 ohm^-1cm^-1 reached at the latter carrier density is comparable to the highest value. We attribute the high mobility to several physical properties of (Ba,La)SnO3: a small effective mass coming from the ideal Sn-O-Sn bonding, small disorder effects due to the doping away from the SnO2 conduction channel, and reduced carrier scattering due to the high dielectric constant. The observation of a reduced mobility of ~70 cm^2(Vs)^-1 in the film is mainly attributed to additional carrier-scatterings which are presumably created by the lattice mismatch between the substrate SrTiO3 and (Ba,La)SnO3. The main optical gap of (Ba,La)SnO3 single crystals remained at about 3.33 eV and the in-gap states only slightly increased, thus maintaining optical transparency in the visible region. Based on these, we suggest that the doped BaSnO3 system holds great potential for realizing all perovskite-based, transparent high-frequency high-power functional devices as well as highly mobile two-dimensional electron gas via interface control of heterostructured films.

description: We report on an estimate of α_s, renormalised in the MSbar scheme at the tau and Z^0 mass scales, by means of lattice QCD. Our major improvement compared to previous lattice calculations is that, for the first time, no perturbative treatment at the charm threshold has been required since we have used statistical samples of gluon fields built by incorporating the vacuum polarisation effects of u/d, s and c sea quarks. Extracting α_s in the Taylor scheme from the lattice measurement of the ghost-ghost-gluon vertex, we obtain α_s^{MSbar}(m^2_Z)=0.1200(14) and α_s^{MSbar}(m^2_tau)=0.339(13).

description: The infrared structure of quantum gravity is explored by solving a lattice version of the Wheeler-DeWitt equations. In the present paper only the case of 2+1 dimensions is considered. The nature of the wavefunction solutions is such that a finite correlation length emerges and naturally cuts off any infrared divergences. Properties of the lattice vacuum are consistent with the existence of an ultraviolet fixed point in $G$ located at the origin, thus precluding the existence of a weak coupling perturbative phase. The correlation length exponent is determined exactly and found to be $ν=6/11$. The results obtained so far lend support to the claim that the Lorentzian and Euclidean formulations belong to the same field-theoretic universality class.

description: We study the coherence dynamics of a kicked two-mode Bose-Hubbard model starting with an arbitrary coherent spin preparation. For preparations in the chaotic regions of phase-space we find a generic behavior with Flouquet participation numbers that scale as the entire $N$-particle Hilbert space, leading to a rapid loss of single particle coherence. However, the chaotic behavior is not uniform throughout the chaotic sea, and unique statistics is found for preparations at the vicinity of hyperbolic points that are embedded in it. This is contrasted with the low log(N) participation that is responsible for the revivals at the vicinity of isolated hyperbolic instabilities.

description: In this study, we present a highly configurable neuromorphic computing substrate and use it for emulating several types of neural networks. At the heart of this system lies a mixed-signal chip, with analog implementations of neurons and synapses and digital transmission of action potentials. Major advantages of this emulation device, which has been explicitly designed as a universal neural network emulator, are its inherent parallelism and high acceleration factor compared to conventional computers. Its configurability allows the realization of almost arbitrary network topologies and the use of widely varied neuronal and synaptic parameters. Fixed-pattern noise inherent to analog circuitry is reduced by calibration routines. An integrated development environment allows neuroscientists to operate the device without any prior knowledge of neuromorphic circuit design. As a showcase for the capabilities of the system, we describe the successful emulation of six different neural networks which cover a broad spectrum of both structure and functionality.

In the unit cell, the dinuclear molecules are well isolated from each other. The non-monotonous dependence of magnetic susceptibility is explained in terms of the hierarchy of exchange parameters by using exact diagonalization. The thermodynamic behavior of pure cpo and [Mn(hfa)2(cpo)]2 is simulated numerically in a dimer approximation by an extrapolation to spin S = 5/2. The Mn-Mn exchange integral is evaluated.

description: We analyze a two-dimensional Pomeranchuk-Nematic instability, trigger by the Landau parameter $F_2<0$, in the presence of a small magnetic field. Using Landau Fermi liquid theory in the isotropic phase, we analyze the collective modes near the quantum critical point $F_2=-1,ω_c=0$ (where $ω_c$ is the cyclotron frequency). We focus on the effects of parity symmetry breaking on the Fermi surface deformation. We show that, for studying the critical regime, the linear response approximation of the Landau-Silin equation is not sufficient and it is necessary to compute corrections at least of order $ω_c^2$. Identifying the slowest oscillation mode in the disordered phase, we compute the phase diagram for the isotropic/nematic phase transition in terms of $F_2$ and $ω_c$.

description: Ideals are one of the main topics of interest to the study of the order structure of an algebra. Due to their nice properties, ideals have an important role both in lattice theory and semigroup theory. Two natural concepts of ideal can be derived, respectively, from the two concepts of order that arise in the context of skew lattices. The correspondence between the ideals of a skew lattice, derived from the preorder, and the ideals of its respective lattice image is clear. Though, skew ideals, derived from the partial order, seem to be closer to the specific nature of skew lattices. In this paper we review ideals in skew lattices and discuss the intersection of this with the study of the coset structure of a skew lattice.

description: Using holography, we compute the Chern-Simons diffusion rate of 4d gauge theories constructed by wrapping D4-branes on a circle. In the model with antiperiodic boundary conditions for fermions, we find that it scales like $T^6$ in the high-temperature phase. With periodic fermions, this scaling persists at low temperatures. The scaling is reminiscent of 6d hydrodynamic behavior even at temperatures small compared to compactification scales of the M5-branes from which the D4-branes descend. We offer a holographic explanation of this behavior by adding a new entry to the known map between D4 and M5 hydrodynamics, and suggest a field theory explanation based on "deconstruction" or "fractionization".

description: In this short article, we study the extremal behavior $F_Γ(n)$ of divisibility functions $D_Γ$ introduced by the first author for finitely generated groups $Γ$. We show finitely generated subgroups of $\GL(m,K)$ for an infinite field $K$ have at most polynomial growth for the function $F_Γ(n)$. Consequently, we obtain a dichotomy for the growth rate of $\log F_Γ(n)$ for finitely generated subgroups of $\GL(n,\C)$. We also show that if $F_Γ(n) \preceq \log \log n$, then $Γ$ is finite. In contrast, when $Γ$ contains an element of infinite order, $\log n \preceq F_Γ(n)$. We end with a brief discussion of some geometric motivation for this work.

description: Using Molecular Dynamics simulations of a polymer liquid flowing past flat and patterned surfaces, we investigate the influence of corrugation, wettability and pressure on slippage and friction at the solid-liquid interface. For one-dimensional, rectangular grooves, we observe a gradual crossover between the Wenzel state, where the liquid fills the grooves, and the Cassie state, where the corrugation supports the liquid and the grooves are filled with vapor. Using two independent flow set-ups, we characterize the near-surface flow by the slip length, $δ$, and the position, $z_\textrm{h}$, at which viscous and frictional stresses are balanced according to Navier's partial slip boundary condition. This hydrodynamic boundary position depends on the pressure inside the channel and may be located above the corrugated surface. In the Cassie state, we observe that the edges of the corrugation contribute to the friction.

description: Personalised nutrition (PN) products and services have the potential to enhance the health and quality of life of older adults. However, PN innovation is challenging and requires specific competencies and supportive collaborations. This paper reports findings from a Collective Intelligence Scenario-Based Design session conducted with PN experts as part of the Horizon 2020 project INCluSilver, which aims to support the development of products, services, and systems that improve the health and quality of life of older adults through innovation in PN. Experts identified challenges to the design of PN products and services and barriers that small and medium enterprises (SMEs) face when innovating PN products and services for older adults. Options to address these barriers were generated and specific SME competencies supporting PN innovation were identified. This study provides a useful framework for understanding the challenges, opportunities, and key competencies needed to innovate PN products and services for older adults.

description: The Mott insulating state formed from bosons is ubiquitous in solid He-4, cold atom systems, Josephson junction networks and perhaps underdoped high-Tc superconductors. We predict that close to the quantum phase transition to the superconducting state the Mott insulator is not at all as featureless as is commonly believed. In three dimensions there is a phase transition to a low temperature state where, under influence of an external current, a superconducting state consisting of a regular array of 'wires' that each carry a quantized flux of supercurrent is realized. This prediction of the "type-II Mott insulator" follows from a field theoretical weak-strong duality, showing that this 'current lattice' is the dual of the famous Abrikosov lattice of magnetic fluxes in normal superconductors. We argue that this can be exploited to investigate experimentally whether preformed Cooper pairs exist in high-Tc superconductors.

description: Electromagnetic (EM) observations of gravitational-wave (GW) sources would bring unique insights into a source which are not available from either channel alone. However EM follow-up of GW events presents new challenges. GW events will have large sky error regions, on the order of 10-100 square degrees, which can be made up of many disjoint patches. When searching such large areas there is potential contamination by EM transients unrelated to the GW event. Furthermore, the characteristics of possible EM counterparts to GW events are also uncertain. It is therefore desirable to be able to assess the statistical significance of a candidate EM counterpart, which can only be done by performing background studies of large data sets. Current image processing pipelines such as that used by ROTSE are not usually optimised for large-scale processing. We have automated the ROTSE image analysis, and supplemented it with a post-processing unit for candidate validation and classification. We also propose a simple ad hoc statistic for ranking candidates as more likely to be associated with the GW trigger. We demonstrate the performance of the automated pipeline and ranking statistic using archival ROTSE data. EM candidates from a randomly selected set of images are compared to a background estimated from the analysis of 102 additional sets of archival images. The pipeline's detection efficiency is computed empirically by re-analysis of the images after adding simulated optical transients that follow typical light curves for gamma-ray burst afterglows and kilonovae. We show that the automated pipeline rejects most background events and is sensitive to simulated transients to limiting magnitudes consistent with the limiting magnitude of the images.
Quark mass hierarchy and mixing via geometry of extra dimension with point interactions

description: We propose a new model which can naturally explain origins of fermion generations, quark mass hierarchy, and Cabibbo-Kobayashi-Maskawa matrix simultaneously from geometry of an extra dimension. We take the extra dimension to be an interval with point interactions, which are additional boundary points in the bulk space of the interval. Because of the Dirichlet boundary condition for fermion at the positions of point interactions, profiles of chiral fermion zero modes are split and localized, and then we can realize three generations from each five-dimensional Dirac fermion. Our model allows fermion flavor mixing but the form of non-diagonal elements of fermion mass matrices is found to be severely restricted due to geometry of the extra dimension. The Robin boundary condition for a scalar leads to an extra coordinate-dependent vacuum expectation value, which can naturally explain the fermion mass hierarchy.

description: In the light of the discovery of a 126 GeV Standard-Model-like Higgs boson at the LHC, we evaluate the achievable accuracies for direct measurements of the width, mass, and the s-channel resonant production cross section of the Higgs boson at a proposed muon collider. We find that with a beam energy resolution of R=0.01% (0.003%) and integrated luminosity of 0.5 fb^{-1} (1 fb^{-1}), a muon collider would enable us to determine the Standard-Model-like Higgs width to +/- 0.35 MeV (+/- 0.15 MeV) by combining two complementary channels of the WW^* and b\bar b final states. A non-Standard-Model Higgs with a broader width is also studied. The unparalleled accuracy potentially attainable at a muon collider would test the Higgs interactions to a high precision.

State Typohumanism and its role in the rise of völkisch-racism: paideía and humanitas at Issue in Jaeger's and Krieck's ‘political Plato'

description: The aim of this article is to provide a philosophical conceptual frameworkto understand the theoretical roots and political implications ofthe interpretations of Plato’s work in Jaeger’s Third Humanism andKrieck’s v€olkisch-racist pedagogy and anthropology. This article will seekto characterize, as figures of localitas, their conceptions of the individual,community, corporeality, identity, and the State that both authors developeddeparting from Platonic political philosophy. My main hypothesisis that Jaeger’s and Krieck’s interpretations of Platonic paide?ıa sharedseveral core-elements based on a modern conception of State sovereigntyand human will, whose fundamental ground is the subjectivisttechnicalmetaphysics. The “production” of a human type (spiritual and/or racial) and a unitary State political community appears in bothauthors mediated by a theory of political education, that I define as«State typohumanism», that sought its sustenance in Plato’s politicalphilosophy, mainly by means of a distorted understanding of thenotions of t?ypos and ?e^thos, and that, I argue, played a key role in theintellectual legitimization of v€olkisch-racism. This would be broadlytranslated into a programmatic and literal understanding of the PlatonicRepublic which assumes that the inherent function of any State is toproduce subjectivities based on national identities grounded on homogeneouscharacteristics. In these varied characterizations similar appropriationsof humanitas have been expressed both in Jaeger andin Krieck.
