description: We present a general approach to measurement-based quantum feedback that employs proportional and quantum state-based (PaQS) feedback components to obtain locally optimal protocols. To demonstrate the power of the method, we first show that it reproduces many known feedback protocols, and then apply it to generation of multipartite entanglement with an emphasis on remote entanglement, which requires spatially local feedback Hamiltonians. The symmetry of both measurement and feedback operators is found to be essential for construction of effective protocols. We show that under perfect measurement efficiency, entangled states can be reached with fidelity approaching unity under non-Markovian feedback control protocols, while Markovian protocols resulting from optimizing the feedback unitaries on ensemble averaged states still yield fidelities above 94%. Application of the PaQS approach to generation of N-qubit W, general Dicke and GHZ states shows that such entangled states can be efficiently generated with high fidelity, for up to N = 100 in some cases.

description: This short course offers a new perspective on randomized algorithms for matrix computations. It explores the distinct ways in which probability can be used to design algorithms for numerical linear algebra. Each design template is illustrated by its application to several computational problems. This treatment establishes conceptual foundations for randomized numerical linear algebra, and it forges links between algorithms that may initially seem unrelated.

description: We study the low energy regime of the scattering of two fermionic particles carrying isospin 1/2 and interacting through a non-Abelian Chern-Simons field. We calculate the one-loop scattering amplitude for both the nonrelativistic and also for the relativistic theory. In the relativistic case we introduce an intermediate cutoff, separating the regions with low and high loop momenta integration. In this procedure purely relativistic field theory effects as the vacuum polarization and anomalous magnetic moment corrections are automatically incorporated.

description: We develop a technique for calculating three-dimensional classical partition functions using projected entangled-pair states (PEPS). Our method is based on variational PEPS optimization algorithms for two-dimensional quantum spin systems, and allows us to compute free energies directly in the thermodynamic limit. The main focus of this work is classical frustration in three-dimensional many-body systems leading to an extensive ground-state degeneracy. We provide high-accuracy results for the residual entropy of the dimer model on the cubic lattice, water-ice $I_h$ and water-ice $I_c$. In addition, we show that these systems are in a Coulomb phase by computing the dipolar form of the correlation functions. As a further benchmark of our methods, we calculate the critical temperature and exponents of the Ising model on the cubic lattice.

description: From the computation of three-point singlet correlators in the two-matrix model, we obtain an explicit expression for the macroscopic three-loop amplitudes having boundary lengths $\ell_{i}$ $(i = 1\sim 3)$ in the case of the unitary series $(p,q)= (m+1,m)$ coupled to two-dimensional gravity. The sum appearing in this expression is found to conform to the structure of the CFT fusion rules while the summand factorizes through a product of three modified Bessel functions. We briefly discuss a possible generalization of these features to macroscopic $n$-loop amplitudes.

description: We have observed the cold collision frequency shift of the 1S-2S transition in trapped spin-polarized atomic hydrogen. We find $Δν_{1S-2S} = -3.8(8)\times 10^{-10} n Hz cm^3$, where $n$ is the sample density. From this we derive the 1S-2S s-wave triplet scattering length, $a_{1S-2S}=-1.4(3)$ nm, which is in fair agreement with a recent calculation. The shift provides a valuable probe of the distribution of densities in a trapped sample.

Throwing a chemical spanner in the malaria invasion motor: Interaction and dynamics of the Plasmodium MTIP/MyoA complex
Creators: name: Thomas, Jemima Carys
Publisher: name: Imperial College London
Year: 2011

description: Malaria kills over one million people per year and has devastating social and economic effects on endemic countries. It is caused by the Plasmodium parasite which has a history of developing resistance to anti-malarial drugs, meaning new therapeutics are urgently required. A key event in the Plasmodium life cycle is the invasion of human erythrocytes. The force for this invasion is derived from an actomyosin motor located inside the parasite plasma membrane. This molecular motor consists of a type XIV myosin, Myosin A (MyoA), bound to myosin tail interacting protein (MTIP). The MTIP/MyoA protein-protein interaction is a potential anti-malarial drug target; disruption of this complex should stall erythrocyte invasion and kill the parasite. In the work discussed in this thesis the MyoA tail was mimicked using short chain peptides for the study of MTIP/MyoA binding in vitro. Development of fluorescence assays for the analysis of MyoA peptide binding to MTIP and the screening of potential inhibitors of this complex is described, together with the application of these assays to identify novel binding motifs at the MTIP/MyoA interface. In combination with peptide arrays, these fluorescence assays were also used to investigate MTIP binding to Myosin B (MyoB), another Plasmodium myosin of unknown function. No binding partners of MyoB have yet been identified in vivo, but results reported here show that MTIP can bind MyoB peptides in vitro. CD spectroscopy and protein NMR experiments were used to investigate the structures of MTIP/MyoA and MTIP/MyoB peptide complexes in solution, and indicate that MTIP undergoes a large conformational change upon myosin peptide binding. These structural techniques together with the fluorescence assays provide a platform for future drug discovery efforts targeting MTIP/MyoA. Finally, the information obtained concerning the MTIP/MyoA interaction was used to design and synthesise α-helix mimetic compounds of MyoA. These compounds were examined for inhibition activity against MTIP/MyoA using fluorescence assays, and appear to be able to disrupt MTIP/MyoA complex formation in vitro. This provides a starting point for future anti-malarial drug development and is a further step towards the chemical validation of MTIP/MyoA as a drug target.

The condensate and normal gas are studied by two-photon spectroscopy of the 1S-2S transition. Interactions among the atoms produce a shift of the resonance frequency proportional to density. The condensate is clearly distinguished by its large frequency shift. The peak condensate density is 4.8 +/- 1.1 \times 10^{15} cm^{-3}, corresponding to a condensate population of 10^9 atoms. The BEC transition occurs at about T=50 uK and n=1.8 \times 10^{14} cm^{-3}.

description: We demonstrate a deep-learning-based scatterer density estimator (SDE) that processes local speckle patterns of optical coherence tomography (OCT) images and estimates the scatterer density behind each speckle pattern. The SDE is trained using large quantities of numerically simulated OCT images and their associated scatterer densities. The numerical simulation uses a noise model that incorporates the spatial properties of three types of noise, i.e., shot noise, relative-intensity noise, and non-optical noise. The SDE's performance was evaluated numerically and experimentally using two types of scattering phantom and in vitro tumor spheroids. The results confirmed that the SDE estimates scatterer densities accurately. The estimation accuracy improved significantly when compared with our previous deep-learning-based SDE, which was trained using numerical speckle patterns generated from a noise model that did not account for the spatial properties of noise.

description: The Voigt profile is important for spectroscopy, astrophysics, and many other fields of physics, but is notoriously difficult to compute. McLean et al. [J. Electron Spectrosc. & Relat. Phenom., 1994] have proposed an approximation using a sum of Lorentzians. Our assessment indicates that this algorithm has significant errors for small arguments. After a brief survey of the requirements for spectroscopy we give a short list of both efficient and accurate codes and recommend implementations based on rational approximations.

Evaluating and Correcting Performative Effects of Decision Support Systems via Causal Domain Shift

description: When predicting a target variable $Y$ from features $X$, the prediction $\hat{Y}$ can be performative: an agent might act on this prediction, affecting the value of $Y$ that we eventually observe. Performative predictions are deliberately prevalent in algorithmic decision support, where a Decision Support System (DSS) provides a prediction for an agent to affect the value of the target variable. When deploying a DSS in high-stakes settings (e.g. healthcare, law, predictive policing, or child welfare screening) it is imperative to carefully assess the performative effects of the DSS. In the case that the DSS serves as an alarm for a predicted negative outcome, naive retraining of the prediction model is bound to result in a model that underestimates the risk, due to effective workings of the previous model. In this work, we propose to model the deployment of a DSS as causal domain shift and provide novel cross-domain identification results for the conditional expectation $E[Y | X]$, allowing for pre- and post-hoc assessment of the deployment of the DSS, and for retraining of a model that assesses the risk under a baseline policy where the DSS is not deployed. Using a running example, we empirically show that a repeated regression procedure provides a practical framework for estimating these quantities, even when the data is affected by sample selection bias and selective labelling, offering for a practical, unified solution for multiple forms of target variable bias.

The role of the cerebellothalamocortical pathway in skilled reaching
Creators: name: Wehry, Hillary
Publisher: name: Carnegie Mellon University
Year: 2024
Subjects: classificationCode: 320999
subject: Neurosciences not elsewhere classified

description: The cerebellothalamocortical pathway has been implicated in a broad array of motor functions ranging from controlling the timing of movements to motor adaptation. There is a considerable gap in knowledge concerning how the cerebellum influences cortical control of the upper limbs via the motor (ventrolateral) thalamus. Despite its position as the direct influencer of cortical activity, the cerebellar motor thalamus has been understudied, likely due to technical difficulties in reliably identifying and recording from this area in awake, behaving primates. Scarcely any work has examined the relationship between the motor thalamus and either the cerebellar output nuclei or the motor cortex. This nucleus is involved in different aspects of motor control, but it is not yet clear how cerebellar signaling is transformed at the level of the thalamus, or how thalamic activity modifies or sustains aspects of cortical activity. My thesis aims to clarify the nature of cerebellar influence on cortical control of movement in primates by investigating functional and trial-by-trial relationships between the primary motor cortex and cerebellar motor thalamus. My thesis focuses on multiple outstanding questions in neural basis of motor control: Does input the cerebellar thalamus to M1 drive movement initiation– or the switch between motor preparation to execution? Do M1 units receiving cerebellar input via the thalamus have a distinct functional role relative to the rest of the M1 network? A combination of simultaneous cortical and thalamic population recordings during reaching, electrical stimulation identification, statistical modeling, and simulation-based validation approaches are used to support our answers to these questions.

Dynamic Data Mining: Methodology and Algorithms
Creators: name: Deng, Xiong
Publisher: name: Imperial College London
Year: 2010

description: Supervised data stream mining has become an important and challenging data mining task in modern organizations. The key challenges are threefold: (1) a possibly infinite number of streaming examples and time-critical analysis constraints; (2) concept drift; and (3) skewed data distributions. To address these three challenges, this thesis proposes the novel dynamic data mining (DDM) methodology by effectively applying supervised ensemble models to data stream mining. DDM can be loosely defined as categorization-organization-selection of supervised ensemble models. It is inspired by the idea that although the underlying concepts in a data stream are time-varying, their distinctions can be identified. Therefore, the models trained on the distinct concepts can be dynamically selected in order to classify incoming examples of similar concepts. First, following the general paradigm of DDM, we examine the different concept-drifting stream mining scenarios and propose corresponding effective and efficient data mining algorithms. • To address concept drift caused merely by changes of variable distributions, which we term pseudo concept drift, base models built on categorized streaming data are organized and selected in line with their corresponding variable distribution characteristics. • To address concept drift caused by changes of variable and class joint distributions, which we term true concept drift, an effective data categorization scheme is introduced. A group of working models is dynamically organized and selected for reacting to the drifting concept. Secondly, we introduce an integration stream mining framework, enabling the paradigm advocated by DDM to be widely applicable for other stream mining problems. Therefore, we are able to introduce easily six effective algorithms for mining data streams with skewed class distributions. In addition, we also introduce a new ensemble model approach for batch learning, following the same methodology. Both theoretical and empirical studies demonstrate its effectiveness. Future work would be targeted at improving the effectiveness and efficiency of the proposed algorithms. Meantime, we would explore the possibilities of using the integration framework to solve other open stream mining research problems.
Fatigue effects in elastic materials with variational damage models: A vanishing viscosity approach

Subjects: subject: Analysis of PDEs (math.AP)

description: We study the existence of quasistatic evolutions for a family of gradient damage models which take into account fatigue, that is the process of weakening in a material due to repeated applied loads. The main feature of these models is the fact that damage is favoured in regions where the cumulation of the elastic strain (or other relevant variables, depend on the model) is higher. To prove the existence of a quasistatic evolution, we follow a vanishing viscosity approach based on two steps: we first let the time-step $τ$ of the time-discretisation and later the viscosity parameter $ε$ go to zero. As $τ\to 0$, we find $ε$-approximate viscous evolutions; then, as $ε\to 0$, we find a rescaled approximate evolution satisfying an energy-dissipation balance.
Glenoid failure in Total Shoulder Arthroplasty
Creators: name: Gregory, Thomas Maurice Stewart
Publisher: name: Imperial College London
Year: 2010

description: Compared to hip and knee, anatomic shoulder arthroplasty is relatively poorly understood, underdeveloped and reported loosening rates are very high, the common cause of failure being glenoid aseptic loosening. The aim of this thesis was first to establish in-vitro and in-vivo CT protocols allowing direct monitoring of glenoid fixation and aseptic loosening and secondly to identify key elements of the procedure that could improve results of prosthetic surgery. First, in-vitro, the ASTM standard method for evaluating loosening of glenoid implants was modified, so that, with the use of CT-scans at regular interval basis, it allows the direct monitoring of the failure observed in the laboratory setting. The failure was observed at the cement-implant interface and progressed from the edges of the implants, both superior and inferior, towards the keel. Secondly, an in-vivo CT protocol was established that eliminates most of the metallic artefacts caused by the humeral head and consequently enhances the visualisation of the radiolucent lines and osteolysis around the glenoid. The link between radiological lucencies and aseptic loosening was confirmed first in a study including 68 cases using this CT protocol, which confirmed the progression of the lucencies over time, and secondly, by the use of Spect-CT. The 3-dimensional spatial (mal)position of the glenoid component and the resulting consequences were analysed in three additional studies. The effect of malposition on clinical results and radiological lucencies; the relationship to the preoperative eroded glenoid and the relationship to polyethylene wear were all investigated. These studies stressed how inaccurately the glenoid components are positioned in clinical practise and that this inaccuracy has a detrimental effect on polyethylene wear; aseptic loosening and ultimately on clinical outcome. Future work should focus on establishing the optimal position of the glenoid implant, and how to achieve this optimal placement in surgical practise.

The phase dependent tunneling term contains both the usual 2pi-periodic Josephson term and a 4pi-periodic Majorana tunneling term representing the coupling between Majoranas on both sides of the junction. In non-topological junctions when the charging energy is small compared to the Josephson tunneling scale the low energy physics is described by 2pi phase slips. By contrast, in a topological junction, due to the 4pi periodicity of the tunneling term it is usually expected that only 4pi phase slips are possible while 2pi phase slips are suppressed. However, we find that if the ratio between the strengths of the Majorana assisted tunneling and the Josephson tunneling is small, as is likely to be the case for many setups, 2pi phase slips occur and may even dominate the low energy physics. In this limit one can view the 4pi phase slips as a pair of 2pi phase slips with arbitrarily large separation. We provide an effective descriptions of the system in terms of 2pi and 4pi phase slips valid for all values of the tunneling ratio. Comparing the spectrum of the effective models with numerical simulations we determine the cross-over between the 4pi phase slip regime to 2pi phase slip dominated regime. We also discuss the role of the charging energy as well as the implications of our results on the dissipative phase transitions expected in such a system.

Magnetic resonance coronary vessel wall imaging with highly efficient respiratory motion correction
Creators: name: Scott, Andrew David
Publisher: name: Imperial College London
Year: 2011

description: There is a need for a noninvasive imaging technique for use in longitudinal studies of sub-clinical coronary artery disease. Magnetic resonance (MR) can be used to selectively and non-invasively image the coronary wall without the use of ionising radiation. However, high-resolution 3D studies are often time consuming and unreliable, as data acquisition is generally gated to a small window of diaphragm positions around end-expiration which results in inherently poor and variable respiratory efficiency. This thesis describes the development and application of a novel technique (beat-to-beat respiratory motion correction (B2B-RMC)) for correcting respiratory motion in 3D spiral MR coronary imaging. This technique uses motion of the epicardial fat surrounding the artery as a surrogate for the motion of the artery itself and enables retrospective motion correction with respiratory efficiency close to 100%. This thesis first describes an assessment of the performance of B2B-RMC using a purpose built respiratory motion phantom with realistic coronary artery test objects. Subsequently, MR coronary angiography studies in healthy volunteers show that the respiratory efficiency of B2B-RMC far exceeds that of conventional navigator gating, yet the respiratory motion correction is equally effective. The performance and reproducibility of 3D spiral imaging with B2B-RMC for assessment of the coronary artery vessel wall is subsequently compared to that of commonly used 2D navigator gated techniques. The results demonstrate the high performance, reproducibility and reliability of 3D spiral imaging with B2B-RMC when data acquisition is gated to alternate cardiac cycles. Using this technique, a further in-vivo study demonstrates thickening of the coronary vessel wall with age in healthy subjects and these results are shown to be consistent with outward remodelling of the vessel wall. Finally, the performance of B2B-RMC in a variety of coronary vessel wall applications, including in a small cohort of patients with confirmed coronary artery disease, is presented.

description: We consider bosonic noncritical strings as QCD strings and we present a basic strategy to construct them in the context of Liouville theory. We show that Dirichlet boundary conditions play important roles in generalized Liouville theory. Specifically, they are used to stabilize the classical configuration of strings and also utilized to treat tachyon condensation in our model. We point out that Dirichlet boundary conditions for the Liouville mode maintains Weyl invariance, if an appropriate condition is satisfied, in the background with a (non-linear) dilaton.

Factors influencing press-fit acetabular cup failure : an experimentally validated finite element study
Creators: name: Clarke, Susannah G.
Publisher: name: Imperial College London
Year: 2011

description: The work undertaken in this thesis uses finite element analysis to investigate the most critical causes of acetabular cup implant failure. To enable accurate conclusions from finite element analysis, three studies have been carried out to strengthen understanding and confidence in finite element model outcomes. Two of these are sensitivity studies, which inform the required level of model definition to enable repeatable results. The third study is an in vitro experimental validation of finite element strains, displacements and cup-bone micromotions; therefore validating the use of the finite element model to predict physical situations. Metal on metal press-fit acetabular cups are the worst performing acetabular cup type with severe failure consequences compared to cups made from more inert materials such as polyethylene or ceramic. The cause of failure of these cup types is widely acknowledged to be multi-factorial, therefore creating a complex scenario for analysis through clinical studies. A factorial analysis has been carried out using finite element analysis to investigate the relative influence of five input factors associated with acetabular cup implantation on output parameters indicating potential failure of the implantation. The factorial analysis concluded that the most significant influences on failure are cup positioning and the interference fit between the acetabular bone and implanted cup; and that these influences have a higher potential to cause failure than the design of the implant used, within the boundaries of the implant design parameters investigated here. Errors in these aspects of surgery may result in acetabular cup failure. It is therefore paramount to reduce errors in the surgical process to enable accurate levels of positioning and interference fit. Time and resources may therefore be best spent developing surgical instrumentation which can increase the accuracy of the implant positioning and fit, and ascertaining the optimal levels of both, rather than designing new implants.

description: Understanding morphological evolution in dinosaurs from a mechanistic viewpoint requires the elucidation of the morphogenesis that gave rise to derived dinosaurian traits, such as the perforated acetabulum. In the current study, we used embryos of extant animals with ancestral- and dinosaur-type acetabula, namely, geckos and turtles (with unperforated acetabulum), and birds (with perforated acetabulum). We performed comparative and experimental analyses, focusing on inter-tissue interaction during embryogenesis, and found that the avian perforated acetabulum develops via a secondary loss of cartilaginous tissue in the acetabular region. This cartilage loss might be mediated by inter-tissue interaction with the hip interzone, a mesenchymal tissue that exists in the embryonic joint structure. Furthermore, the data indicate that avian pelvic anlagen is more susceptible to paracrine molecules, e.g. Wnt ligand, secreted by the hip interzone than ‘reptilian’ anlagen. We hypothesize that during the emergence of dinosaurs, the pelvic anlagen became susceptible to the Wnt ligand, which led to the loss of the cartilaginous tissue and to the perforation in the acetabular region. Thus, the current evolutionary-developmental biology study deepens our understanding of morphological evolution in dinosaurs and provides it with a novel perspective.
Patent Foramen Ovale in Obstructive Sleep Apnoea and Chronic Obstructive Pulmonary Disease
Creators: name: Shaikh, Zarrin F

Year: 2011

description: The objective of this thesis was to determine the impact of right to left shunting (RLS) through patent foramen ovale (PFO) on oxygen saturation in obstructive sleep apnoea (OSA) and chronic obstructive pulmonary disease (COPD). The first aim was to determine the prevalence of PFO in severe OSA and whether PFO closure improves nocturnal oxygen saturation. The data showed that PFO with large shunts were more prevalent, however overall prevalence was not statistically different when compared to healthy controls. PFO closure did not reduce nocturnal desaturation. The second aim was to determine whether severe COPD patients with PaO2 ≤ 7.3kPa had a higher prevalence of PFO compared to patients with PaO2 > 8kPa, additionally to compare the prevalence of PFO in COPD with healthy controls. The data showed no difference in PFO prevalence in patients with PaO2 ≤ 7.3kPa compared to patients with PaO2 > 8kPa, however, intrapulmonary shunts were more prevalent in hypoxaemic patients. Similar to OSA, PFO with large shunts were more prevalent in severe COPD, however overall prevalence was not statistically different to healthy controls. The final aim was to determine whether patients with COPD and PFO developed RLS during exercise and whether this was associated with reduced oxygen saturation, reduced exercise endurance and increased intrathoracic pressure swings. The data showed that RLS through PFO increased from baseline during exercise and this was associated with increased swings in intrathoracic pressure. There was no difference in desaturation or exercise endurance when compared to patients with no PFO. In summary, this thesis shows that PFO with large shunts are more prevalent in both OSA and COPD. PFO closure in OSA did not reduce nocturnal desaturation. Furthermore, the presence of a PFO in COPD did not influence resting or exercise oxygen saturation despite the observed increase in RLS with exercise.

description: We give a simple geometric description of all formal deformation quantizations on a Kähler manifold $M$ which enjoy the following property of separation of variables into holomorphic and antiholomorphic ones. For each open subset $U\subset M$, $\star$-multiplication from the left by a holomorphic function and from the right by an antiholomorphic function on $U$ coincides with the pointwise multiplication by these functions. These quantizations are in 1-1 correspondence with formal deformations of the original Kähler metrics on $M$. It has been shown in [Ka] that the formal deformation quantizations obtained from the full asymptotic expansion of Berezin's $*$-product on the orbits of a compact semisimple Lie group in [Mo2] and [CGR1] and on bounded symmetric domains in [Mo1] and [CGR2] are those with separation of variables and correspond to the trivial deformation of the original Kähler metrics.

The role of the coagulation system in the pathogenesis of liver injury
Creators: name: Dhar, Ameet
Publisher: name: Imperial College London
Year: 2011

description: There is a growing body of evidence that suggests a role for the coagulation cascade in promoting liver injury, in particular fibrosis. With the exception of thrombin, the expression and role of individual coagulation proteins in liver injury is poorly understood. The aim of this body of work was to further our understanding of the role of specific coagulation proteins in liver injury and consider viable targets as anti-fibrotic therapies. We examined these concepts using immunohistochemical, cell line, and animal based studies as well as translational studies in human subjects. Using immunohistochemical techniques, upregulation of coagulation proteins in both acute and chronic liver injury in mice and humans was demonstrated and correlated with severity of injury. Data from cell line studies demonstrated stellate cells, the principal cell involved in hepatic fibrosis, were sensitive to both thrombin and Factor Xa. Furthermore the direct inhibition of both thrombin and Factor Xa using novel anticoagulants in cell line studies and chemical induced murine models of liver fibrosis exhibited anti-fibrotic effects. Two unique translational studies were undertaken to determine the applicability of these findings in humans. A pilot study demonstrated that warfarin anticoagulation resulted in a significant reduction in liver stiffness measurements, a surrogate marker of liver fibrosis, in patients with pre-existing hepatitis C related liver fibrosis, and the interim results of a larger study, performed in the setting of hepatitis C post liver transplantation, has shown a reduction in fibrosis scores. The studies presented in this thesis add to the growing body of evidence suggesting a role for coagulation proteins in the pathogenesis of liver injury and are the first to show the potential anti-fibrotic benefits of both novel anticoagulants in murine models of liver fibrosis and warfarin anticoagulation in patients with hepatitis C related liver fibrosis pre and post transplantation.
