Machine learning for ultrasound brain imaging
Creators: name: Strong, George
Publisher: name: Imperial College London

description: Clinical diagnosis and treatment of stroke is limited by the absence of rapid, transportable, cost-effective and universally safe brain imaging. Full-waveform inversion (FWI) of transcranial ultrasound has recently been proposed as a potential solution. Despite its promise, a fundamental limitation of FWI is that it is a highly non-linear inverse problem. I address this through the transfer of various geophysical imaging techniques to medical ultrasound. Superior performance across numerous tests is obtained by graph-space optimal transport and adaptive waveform inversion. I then explore the clinical utility of FWI for stroke diagnosis by constructing an anatomically realistic data set of acoustic properties for stroke-perturbed human head models, for which three-dimensional in silico experiments were conducted. The results demonstrate that FWI is able to illuminate all stroke-relevant features that are currently detectable using diagnostic stroke-related clinical neuroimaging techniques. Commonalities between FWI and machine learning have been exploited throughout this thesis via the creation and use of a PyTorch-based FWI library. This facilitated the regularisation of FWI using traditional priors, and the development of a deep learning-based prior that leverages the hierarchical nature of pre-trained convolutional neural networks. Finally, I introduce the Wiener diffusion, a novel non-parametric generative model. I demonstrate that it is well suited to tasks with limited data, is flexible at inference time, and discuss how it can be readily incorporated within FWI to improve and accelerate convergence. The findings of this research have the potential to significantly enhance the utility of brain imaging, particularly in the diagnosis of stroke, a major contributor to global mortality and impairment.

description: Recent work in the area of interdependent networks has focused on interactions between two systems of the same type. However, an important and ubiquitous class of systems are those involving monitoring and control, an example of interdependence between processes that are very different. In this Article, we introduce a framework for modelling distributed supervisory control in the guise of an electrical network supervised by a distributed system of control devices. The system is characterised by degrees of freedom salient to real-world systems--- namely, the number of control devices, their inherent reliability, and the topology of the control network. Surprisingly, the behavior of the system depends crucially on the reliability of control devices. When devices are completely reliable, cascade sizes are percolation controlled; the number of devices being the relevant parameter. For unreliable devices, the topology of the control network is important and can dramatically reduce the resilience of the system.

Characterisation of immune responses to vaccination against SARS-CoV-2
Creators: name: Elliott, Tamara
Publisher: name: Imperial College London
Year: 2023

description: The outbreak of the COVID-19 pandemic highlighted the importance of effective vaccinations that can be rapidly adapted and produced. COVID-19 mRNA vaccines, that had never previously been approved for use against any infectious pathogen, were shown to be extremely effective for protection against severe disease, and billions of doses have since been administered globally. Self-amplifying RNA (saRNA) vaccines display many similarities to mRNA vaccines, but with the potential to be given at lower doses due to the capacity to replicate mRNA within the target cells. A first-in-human clinical trial for a novel COVID-19 saRNA vaccine (COVAC1) demonstrated the safety of this vaccine, but with reduced immunogenicity. Throughout this body of work, I have explored in more detail the humoral and cellular responses following this saRNA vaccination in individuals with or without previous COVID-19, and have made a comparison with mRNA vaccina>on (BNT162b2). I have also endeavoured to look at the differences in early innate responses to both vaccinations. I found that although most individuals seroconverted following saRNA, this was still sub-optimal compared to mRNA. However, BNT162b2 delivery following completion of the saRNA course, resulted in a robust antibody and cellular response, especially evident in those with previous COVID-19. Interestingly, those who received both saRNA and mRNA appeared to have enhanced antigen specific CD8+ T cell responses, characterised by an activated mature memory phenotype. Analysis of soluble mediators at 24-hours following vaccination showed increased concentrations of pro-inflammatory cytokines and chemokines following saRNA compared to mRNA. Coupled with this, transcriptomic analysis demonstrated a more pronounced increase in genes for inflammatory mediators following saRNA. Taken together, the data presented throughout this thesis suggest an immune benefit of saRNA given with mRNA (particularly in COVID-19 convalescence). Additional work needs to be done to optimise this vaccine platform, perhaps with an aim to reduce early inflammation which may result in an improved antigen expression and immune response.

description: Lorentz invariance is a fundamental symmetry of both Einstein's theory of general relativity and quantum field theory. However, deviations from Lorentz invariance at energies approaching the Planck scale are predicted in many quantum gravity theories seeking to unify the force of gravity with the other three fundamental forces of matter. Even though any violations of Lorentz invariance are expected to be very small at observable energies, they can increase with energy and accumulate to detectable levels over large distances. Astrophysical observations involving high-energy emissions and long baselines can therefore offer exceptionally sensitive tests of Lorentz invariance. With the extreme features of astrophysical phenomena, it is possible to effectively search for signatures of Lorentz invariance violations (LIV) in the photon sector, such as vacuum dispersion, vacuum birefringence, photon decay, and photon splitting. All of these potential signatures have been studied carefully using different methods over the past few decades. This chapter attempts to review the status of our current knowledge and understanding of LIV, with particular emphasis on a summary of various astrophysical tests that have been used to set lower limits on the LIV energy scales.

description: We describe how the dynamics of cosmic structure formation defines the intricate geometric structure of the spine of the cosmic web. The Zeldovich approximation is used to model the backbone of the cosmic web in terms of its singularity structure. The description by Arnold et al. (1982) in terms of catastrophe theory forms the basis of our analysis. This two-dimensional analysis involves a profound assessment of the Lagrangian and Eulerian projections of the gravitationally evolving four-dimensional phase-space manifold. It involves the identification of the complete family of singularity classes, and the corresponding caustics that we see emerging as structure in Eulerian space evolves. In particular, as it is instrumental in outlining the spatial network of the cosmic web, we investigate the nature of spatial connections between these singularities. The major finding of our study is that all singularities are located on a set of lines in Lagrangian space. All dynamical processes related to the caustics are concentrated near these lines. We demonstrate and discuss extensively how all 2D singularities are to be found on these lines. When mapping this spatial pattern of lines to Eulerian space, we find a growing connectedness between initially disjoint lines, resulting in a percolating network. In other words, the lines form the blueprint for the global geometric evolution of the cosmic web.

description: Given a digraph D, the complementarity spectrum of the digraph is defined as the set of complementarity eigenvalues of its adjacency matrix. This complementarity spectrum has been shown to be useful in several fields, particularly in spectral graph theory. The differences between the properties of the complementarity spectrum for (undirected) graphs and for digraphs, makes the study of the latter of particular interest, and characterizing strongly connected digraphs with a small number of complementarity eigenvalues is a non trivial problem. Recently, strongly connected digraphs with one and two complementarity eigenvalues have been completely characterized. In this paper we study strongly connected digraphs with exactly three elements in the complementarity spectrum, ending with a complete characterization. This leads to a structural characterization of general digraphs having three complementarity eigenvalues.

Tra tutti i sistemi stellari binari, quelli costituiti da stelle di neutroni e stelle simili al Sole sono piuttosto rari. Si stima che circa una stella di tipo solare su un milione orbiti attorno a una stella di neutroni, in un'orbita ampia. Un nuovo studio guidato dal Caltech ne ha trovati ventuno, grazie alle capacità del satellite Gaia di rilevare le piccolissime oscillazioni indotte dalle stelle di neutroni sulle compagne

description: We present systematic spectral analyses of GRBs detected with the Burst and Transient Source Experiment (BATSE) onboard the Compton Gamma-Ray Observatory (CGRO) during its entire nine years of operation. This catalog contains two types of spectra extracted from 2145 GRBs and fitted with five different spectral models resulting in a compendium of over 19000 spectra. The models were selected based on their empirical importance to the spectral shape of many GRBs, and the analysis performed was devised to be as thorough and objective as possible. We describe in detail our procedures and criteria for the analyses, and present the bulk results in the form of parameter distributions. This catalog should be considered an official product from the BATSE Science Team, and the data files containing the complete results are available from the High-Energy Astrophysics Science Archive Research Center (HEASARC).

Exact domain wall theory for deterministic TASEP with parallel update

description: Domain wall theory (DWT) has proved to be a powerful tool for the analysis of one-dimensional transport processes. A simple version of it was found very accurate for the Totally Asymmetric Simple Exclusion Process (TASEP) with random sequential update. However, a general implementation of DWT is still missing in the case of updates with less fluctuations, which are often more relevant for applications. Here we develop an exact DWT for TASEP with parallel update and deterministic (p=1) bulk motion. Remarkably, the dynamics of this system can be described by the motion of a domain wall not only on the coarse-grained level but also exactly on the microscopic scale for arbitrary system size. All properties of this TASEP, time-dependent and stationary, are shown to follow from the solution of a bivariate master equation whose variables are not only the position but also the velocity of the domain wall. In the continuum limit this exactly soluble model then allows us to perform a first principle derivation of a Fokker-Planck equation for the position of the wall. The diffusion constant appearing in this equation differs from the one obtained with the traditional `simple' DWT.

description: We systematically construct a class of two-dimensional $(2,2)$ supersymmetric gauged linear sigma models with phases in which a continuous subgroup of the gauge group is totally unbroken. We study some of their properties by employing a recently developed technique. The focus of the present work is on models with one Kähler parameter. The models include those corresponding to Calabi-Yau threefolds, extending three examples found earlier by a few more, as well as Calabi-Yau manifolds of other dimensions and non-Calabi-Yau manifolds. The construction leads to predictions of equivalences of D-brane categories, systematically extending earlier examples. There is another type of surprise. Two distinct superconformal field theories corresponding to Calabi-Yau threefolds with different Hodge numbers, $h^{2,1}=23$ versus $h^{2,1}=59$, have exactly the same quantum Kähler moduli space. The strong-weak duality plays a crucial rôle in confirming this, and also is useful in the actual computation of the metric on the moduli space.

description: Muon catalyzed fusion ($μ$CF) has recently regained considerable research interest owing to several new developments and applications. In this regard, we have performed a comprehensive study of the most important fusion reaction, namely $(dtμ)_{J=v=0}\toα$+$n$+$μ$+17.6 MeV or $(αμ)_{nl}$+$n$+17.6 MeV. The coupled-channels Schrödinger equation for the reaction is thus solved, satisfying the boundary condition for the muonic molecule $(dtμ)_{\rm J=v=0}$ as the initial state and the outgoing $αn μ$ channel with the $α$-$n$ $D$ wave. We employ the $dtμ$- and $αn μ$-channel coupled three-body model. All the $d$-$t$ and $α$-$n$ potentials, and the $d t$-$αn$ channel-coupling nonlocal tensor potential are chosen to reproduce the observed low-energy astrophysical $S$-factor of the reaction $d$+$t\toα$+$n$+17.6 MeV, as well as the total cross section of the $α$+$n$ reaction. The resultant $dtμ$ fusion rate is 1.15x10$^{12}$ s$^{-1}$. Substituting the obtained total wave function into the $T$ matrix, we have calculated absolute values of the fusion rates going to the bound and continuum states of the outgoing $α$-$μ$ pair. We then derived the initial $α$-$μ$ sticking probability $ω_S^0$=0.857%, which is $\sim$7% smaller than the literature values ($\simeq$0.91-0.93%), and can explain the recent observations (2001) at high D-T densities. We also calculate the absolute values for the momentum and energy spectra of the emitted muon. The most important result is that the peak energy is 1.1 keV although the mean energy is 9.5 keV. This is an essential result for the ongoing experimental project to realize the generation of an ultra-slow negative muon beam by utilizing the $μ$CF for various applications e.g., a scanning negative muon microscope and an injection source for the muon collider.

description: The past decade's discovery of topological excitations in nanoscale ferroelectrics has turned the prevailing view that the polar ground state in these materials is uniform. However, the systematic understanding of the topological polar structures in ferroelectrics is still on track. Here we study stable vortex-like textures of polarization in the nanocylinders of ferroelectric PbTiO$_3$, arising due to the competition of the elastic and electrostatic interactions. Using the phase-field numerical modeling and analytical calculations, we show that the orientation of the vortex core with respect to the cylinder axis is tuned by the geometrical parameters and temperature of the system.

description: We present a fully quantum-mechanical model of the electronic dynamics of primary photoexcitations in a polymeric semiconductor heterojunction, which includes both polymer stacking and phonon relaxation. By examining the phonon-induced fluctuations in the state-to-state energy gaps and the exact golden-rule rate constants, we conclude that resonant tunnelling between the primary exciton to delocalized interchain charge-transfer states may be the initial step in the formation of charge-carriers in polymer-based bulk-heterojunction photovoltaic diodes.
Decoherence Effect of Qubits in 1D Transverse Ising Model

description: With the development of lab technology, the low-order correlation function can no longer describe the main effect of decoherence in quantum many-body system, so it is imperative to study the higher-order correlation function of the system. In this paper, we study the changes of the correlation functions in the decoherence effect, analytically. And explore when it is possible to approach the qubit decoherence process only by low-order correlation function, and when third-order or higher correlation functions are needed in 1D transverse Ising model. It indicates that, under strong coupling and long coherence time, the effect of high-order correlation functions can not be ignored, and the approximation of classical Markov process is limited. But, in the case of weak coupling and short coherence time, low-order correlation function can describe well.

description: This short note is a review of the intriguing connection between the quantum Gaudin model and the classical KP hierarchy recently established in [1]. We construct the generating function of integrals of motion for the quantum Gaudin model with twisted boundary conditions (the master T-operator) and show that it satisfies the bilinear identity and Hirota equations for the classical KP hierarchy. This implies that zeros of eigenvalues of the master $T$-operator in the spectral parameter have the same dynamics as the Calogero-Moser system of particles.
