description: We present proper motion measurements of Boötes III, an enigmatic stellar satellite of the Milky Way, utilizing data from the second data release of the Gaia mission. By selecting 15 radial velocity confirmed members of Boötes III, along with a likely RR Lyrae member in the vicinity, we measure an error weighted mean proper motion of $(μ_α \cosδ, μ_δ) = (-1.14, -0.98)\pm(0.18, 0.20)$ mas/yr. We select and present further stars that may be Boötes III members based on their combined proper motion and position in the color magnitude diagram. We caution against assigning membership to stars that are not confirmed spectroscopically, as we demonstrate that there are contaminating stars from the disrupting globular cluster NGC 5466 in the vicinity of the main body of Boötes III, but we note that our results are consistent with previous Boötes III proper motion estimates that did not include spectroscopic members. Based on the measured proper motion and other known properties of Boötes III, we derive its Galactocentric velocity and compute its orbit given canonical Milky Way potentials with halo masses of both 0.8$\times$10$^{12}$ M$_{\odot}$ and 1.6$\times$10$^{12}$ M$_{\odot}$. These orbits robustly show that Boötes III passed within $\sim$12 kpc of the Galactic center on an eccentric orbit roughly 140 Myr ago. Additionally, the proper motion of Boötes III is in excellent agreement with predictions for the retrograde motion of the coincident Styx stellar stream. Given this, along with the small pericenter and metallicity spread of Boötes III itself, we suggest that it is a disrupting dwarf galaxy giving rise to the Styx stellar stream.

description: We study the electron scattering produced by local out-of-plane strain deformations in the form of Gaussian bumps in graphene. Of special interest is to take into account the scalar field associated with the redistribution of charge due to deformations, and in the same footing as the pseudomagnetic field. Working with the Born approximation approach we show analytically that even when a relatively small scalar field is considered, a rather strong valley asymmetric scattering could arise as a function of the energy and angle of incidence. In addition, we find that the valley polarization can reverse its sign as the incident energy is increased. These behaviors are totally absent if the scalar field is neglected. These results are supported by quantum dynamical simulations of electron wave packets. Results for the average trajectories of wave packets in locally strained graphene clearly show focusing and beam splitting effects enhanced by the presence of the scalar field that can be of interest in the implementation of valleytronic devices.

Instabilities in high Reynolds number flows
Creators: name: Banks, Curtis Alwyn
Publisher: name: Imperial College London
Year: 2015

description: An asymptotic method for predicting stability characteristics, both stationary and travelling crossflow vortices, over a variety of surface variations was created. These include flat, convex and concave curved surfaces. Comparisons were made with two different numerical methods (Parabolised Stability Equations and Velocity-Vorticity) and good agreement, to within 5% of the numerical value of the crossflow mode streamwise growth rate was met for both stationary and travelling modes initially for a flat surface. An additional comparison was made with the streamwise growth rates to observe the impact of including curvature and a small convex curvature surface variation was used. Similar results were achieved for this study also. Likewise results for travelling crossflow modes were with accordance with the numerical values. To understand how effective this disturbance in penetrating the boundary-layer, receptivity analysis was developed to analyse various mechanisms in the production of crossflow vortices. A response function was established from the receptivity analysis to calculate the efficiency of this process. The response function is largest near the leading edge, meaning the disturbance is most effective at propagating into the boundary layer there. This means that the approach qualitatively agrees with other research methods. This is true for all surface curvatures and both crossflow modes. There is an intriguing behaviour the response function exhibits for small concave curvature with travelling modes at a moderate frequency. When we consider moderate spanwise wavenumber, the response function is much larger than other modes or surface variation and this could have repercussions for experiments. Careful consideration is needed for this case and can be avoided with the aid of this research. Finally, an asymptotic theory was created to analyse two-dimensional closed streamlines for secondary instabilities. The first instability analysed was the elliptical instability, due to the links to turbulence and the initial interest in this general problem. The method anticipates the existence of short-wave three-dimensional disturbances on a streamline at a distance away from the centre of the vortex of this secondary instability. There was no limitation in the study for symmetrical known streamlines, the analysis can be extended further to analyse any two-dimensional closed streamline such as separation bubbles. With this in mind an observation was required to test this hypothesis and the approach was tested on the structure inside a cavity, from which the location and behaviour of the disturbance was correctly predicted.

New statistical estimation methodology for active learning and classification
Creators: name: Evans, Lewis Percival Gordon
Publisher: name: Imperial College London
Year: 2015

description: Object classification by learning from data is a vast area of statistics and machine learning. Within classification, unlabelled data may be plentiful, allowing a few objects to be chosen for labelling by an expert. Systematically choosing these few objects can maximise classifier improvement: this is the problem of active learning (AL). Many heuristic methods coexist with theoretical approaches making substantial assumptions, leaving a gulf between theory and practice. There is a plethora of applications demanding better algorithms and understanding. Experimental studies give a very mixed picture of results, making AL performance rather mysterious. To explore this, a large scale empirical study examines performance in detail. One approach to active learning is to consider the optimal selection behaviour. Defining optimality by classifier improvement produces a new characterisation of optimal AL behaviour. This optimum yields theoretical insights and practical algorithms for applications, unifying theory and practice. This approach is model retraining improvement (MRI), a novel statistical estimation framework for AL. MRI generates a new guarantee for AL, that an unbiased MRI estimator should outperform random selection on average. New statistical AL algorithms are constructed to estimate the MRI optimum, revealing intricate estimation issues. One new algorithm in particular performs strongly in a large-scale experimental study, compared to standard AL methods. MRI is entirely general in terms of problems, classifiers and loss functions. AL shows that classification examples are not created equal; this diversity of example quality implies that systematic selection and modification can both improve classifier performance. This idea is extended to classification, where label improbability gives a new definition of quality (improbability given the covariates). Handling improbable labels (HIL) defines actions to modify the training data, by pruning, relabelling and weighting, to reduce the impact of the improbable labels. Two large experimental studies establish the effectiveness of HIL algorithms.
The forest of merger history trees associated with the formation of dark matter halos

Year: 1998

description: We describe a simple efficient algorithm that allows one to construct Monte-Carlo realizations of merger histories of dark matter halos. The algorithm is motivated by the excursion set model (Bond et al. 1991) for the conditional and unconditional halo mass functions. The forest of trees constructed using this algorithm depends on the underlying power spectrum. For Poisson or white-noise initial power-spectra, the forest has exactly the same properties as the ensemble of trees described by Sheth (1996) and Sheth & Pitman (1997). In this case, many ensemble averaged higher order statistics of the tree distribution can be computed analytically. For Gaussian initial conditions with more general power-spectra, mean properties of the ensemble closely resemble the mean properties expected from the excursion set approach. Various statistical quantities associated with the trees constructed using our algorithm are in good agreement with what is measured in numerical simulations of hierarchical gravitational clustering.

Wide-baseline image change detection
Creators: name: Jones, Zygmunt
Publisher: name: Imperial College London
Year: 2015

description: Growth in the prevalence of cameras has resulted in larger amounts of available image data. This has resulted in demand for automated methods of analysing this data. One key area of demand is automated change detection, the automated detection of changes in a scene, as recorded by a reference and sample image. Established methods of change detection tend to rely on the reference and sample image being captured from the same position, but much of the available data does not fit this criteria. This thesis presents novel approaches to key challenges in wide-baseline cases involving differences in viewing angle of up to 30 degrees, including registration and the image region matching that are robust to the inherent registration errors. The developed algorithms are then combined into an end-to-end system. This thesis presents novel registration approaches including the use of a Delaunay triangulation mask that enables registration of each component triangle, a method of finding local planes in scenes by clustering matched feature points, the use of edge detection to register the edges of objects, and a method for registering planes that are orthogonal to a defined image plane and to the camera line. These techniques allow for the registration of complex 3D scenes with viewing angles of up to 30 degrees. The density of the available correspondences obtained using feature points is a key limiting factor in these methods and so ASIFT, a extension to the SIFT feature point that improves performance at wide angles is also introduced. ASIFT is shown to have an order of magnitude increase in correctly matches feature point density at 30 degrees. Though robust to wide differences in viewing angle, these registration techniques do nonetheless introduce registration errors of up to a few dozen pixels. For this reason the dense SIFT and shifted dense SIFT image comparison algorithms which are robust to registration errors of a few dozen pixels are also developed. The development of these comparison methods includes an analysis of SIFT descriptor statistics and their correlation. Finally these techniques are combined to form an end-to-end change detection system which is evaluated on a number of test datasets.

Combining reinforcement learning and optimal control for the control of nonlinear dynamical systems
Creators: name: Abramova, Ekaterina
Publisher: name: Imperial College London
Year: 2015

description: This thesis presents a novel hierarchical learning framework, Reinforcement Learning Optimal Control, for controlling nonlinear dynamical systems with continuous states and actions. The adapted approach mimics the neural computations that allow our brain to bridge across the divide between symbolic action-selection and low-level actuation control by operating at two levels of abstraction. First, current findings demonstrate that at the level of limb coordination human behaviour is explained by linear optimal feedback control theory, where cost functions match energy and timing constraints of tasks. Second, humans learn cognitive tasks involving learning symbolic level action selection, in terms of both model-free and model-based reinforcement learning algorithms. We postulate that the ease with which humans learn complex nonlinear tasks arises from combining these two levels of abstraction. The Reinforcement Learning Optimal Control framework learns the local task dynamics from naive experience using an expectation maximization algorithm for estimation of linear dynamical systems and forms locally optimal Linear Quadratic Regulators, producing continuous low-level control. A high-level reinforcement learning agent uses these available controllers as actions and learns how to combine them in state space, while maximizing a long term reward. The optimal control costs form training signals for high-level symbolic learner. The algorithm demonstrates that a small number of locally optimal linear controllers can be combined in a smart way to solve global nonlinear control problems and forms a proof-of-principle to how the brain may bridge the divide between low-level continuous control and high-level symbolic action selection. It competes in terms of computational cost and solution quality with state-of-the-art control, which is illustrated with solutions to benchmark problems.

description: We analyze the possibility to accommodate current $b \to s \ell^+ \ell^-$ anomalies with TeV-scale mediators that couple to right-handed top quarks and muons, contributing to $b \to s \ell^+ \ell^-\,$ at the one-loop level. We use the Standard Model Effective Field Theory (SMEFT) framework but also look at specific scenarios by taking into account all possible irreducible representations of the Lorentz and Standard Model gauge group for the mediators. From a global fit of $b \to s \ell^+ \ell^-$ data and LEP-I observables we find that the Wilson coefficients of two SMEFT operators: $\mathcal{O}_{\ell u}= (\bar \ell_{ L μ} γ^α \ell_{ L μ}) (\bar t_R γ_α t_R )$ and $\mathcal{O}_{e u}= (\bar μ_{R} γ^α μ_{R}) (\bar t_R γ_α t_R )$ need to satisfy $\mathcal{C}_{eu} \sim \mathcal{C}_{\ell u}$. New physics enters then in $b \to s \ell^+ \ell^-$ mainly through the operator $\mathcal{O}_9 = ( \bar s γ_μ P_{L} b )( \bar \ell γ^μ \ell )$ of the Weak Effective Theory. After discussing all possible mediators, we concentrate on two scenarios: A vector boson in the irreducible representation $Z_μ^{\prime} \sim (1,1,0)$ of the Standard Model gauge group with vectorial coupling to muons, and a combination of two leptoquarks: the scalar $R_2 \sim (3,2,7/6)$ and the vector $\widetilde U_{1 μ} \sim (3,1,5/3)$. We derive LHC constraints by recasting di-muon resonance, $pp \to t \bar t t \bar t$ and SUSY searches. Additionally, we analyze the prospects for discovering these mediators during the high-luminosity phase of the LHC.

description: Proton momentum distributions of the $^{12}C$, $^{16}O$, $^{40}Ca$, $^{56}Fe$ and $^{208}$Pb nuclei are calculated by a model using the natural orbital representation and the experimental data for the momentum distribution of the $^{4}He$ nucleus. The model allows realistic momentum distributions to be obtained using only hole-state natural orbitals (or mean-field single-particle wave functions as a good approximation to them). To demonstrate the model two different sets of wave functions were employed and the predictions were compared with the available empirical data and other theoretical results.

description: We present both the experimental and theoretical investigation of a non-trivial electron Landau levels shift in magnetic field in wide ~20 nm HgTe quantum wells: Landau levels split under magnetic fields but become degenerate again when magnetic field increases. We reproduced this behavior qualitatively within an isotropic 6-band Kane model, then using semiclassical calculations we showed this behavior is due to the mixing of the conduction band with total spin 3/2 with the next well subband with spin 1/2 which reduces the average vertical spin from 3/2 to around 1. This change of the average spin changes the Berry phase explaining the evolution of Landau levels under magnetic field.

description: The Cosmic Infrared Background (CIB) is hidden behind veils of foreground emission from our own solar system and Galaxy. This paper describes procedures for removing the Galactic IR emission from the 1.25 - 240 micron COBE DIRBE maps as steps toward the ultimate goal of detecting the CIB. The Galactic emission models are carefully chosen and constructed so that the isotropic CIB is completely retained in the residual sky maps. We start with DIRBE data from which the scattered light and thermal emission of the interplanetary dust (IPD) cloud have already been removed. Locations affected by the emission from bright compact and stellar sources are excluded from the analysis. The unresolved emission of faint stars at near- and mid-IR wavelengths is represented by a model based on Galactic source counts. The 100 micron DIRBE observations are used as the spatial template for the interstellar medium (ISM) emission at high latitudes. Correlation of the 100 micron data with H I column density allows us to isolate the component of the observed emission that is associated with the ISM. Limits are established on the far-IR emissivity of the diffuse ionized medium, which indicate a lower emissivity per H nucleus than in the neutral medium. At 240 micron, we find that adding a second spatial template to the ISM model can greatly improve the accuracy of the model at low latitudes. The crucial product of this analysis is a set of all-sky IR maps from which the Galactic (and IPD) emission has been removed. We discuss systematic uncertainties and potential errors in the foreground subtraction process that may have an impact on studies seeking to detect the CIB in the residual maps.

description: Simultaneous modeling of the spatio-temporal variation patterns of brain functional network from 4D fMRI data has been an important yet challenging problem for the field of cognitive neuroscience and medical image analysis. Inspired by the recent success in applying deep learning for functional brain decoding and encoding, in this work we propose a spatio-temporal convolutional neural network (ST-CNN)to jointly learn the spatial and temporal patterns of targeted network from the training data and perform automatic, pin-pointing functional network identification. The proposed ST-CNN is evaluated by the task of identifying the Default Mode Network (DMN) from fMRI data. Results show that while the framework is only trained on one fMRI dataset,it has the sufficient generalizability to identify the DMN from different populations of data as well as different cognitive tasks. Further investigation into the results show that the superior performance of ST-CNN is driven by the jointly-learning scheme, which capture the intrinsic relationship between the spatial and temporal characteristic of DMN and ensures the accurate identification.

Evidence for a massive BH in the S0 galaxy NGC 4342

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: We present axisymmetric dynamical models of the edge-on S0 galaxy NGC 4342. A combination of observations from the ground and with the Hubble Space Telescope (HST) has shown that NGC 4342 rotates rapidly and has a strong central increase in velocity dispersion. We construct simple two-integral Jeans models as well as fully general, three-integral models. The latter are built using a modified version of Schwarzschild's orbit-superposition technique. The two-integral Jeans models suggest a black hole (BH) mass between 3 and 6x10^8 Msun, depending on the data set used to constrain the model, but they fail to fit the details of the observed kinematics. The three-integral models can fit all ground-based and HST data simultaneously, but only when a central BH is included. Models without BH are ruled out to a confidence level better than 99.73 per cent. We determine a BH mass of 3x10^8 Msun. This corresponds to 2.6 per cent of the total mass of the bulge, making NGC 4342 one of the galaxies with the highest BH mass to bulge mass ratio currently known. The models that best fit the data do not have a two-integral phase-space distribution function. They have rather complex dynamical structures: the velocity anisotropies are strong functions of radius reflecting the multi-component structure of this galaxy. The best fit model without BH tries to fit the high central velocity dispersion by placing stars on radial orbits. The measured rotation velocities, however, restrict the amount of radial anisotropy such that the central velocity dispersion measured with the HST can only be fit when a massive BH is included in the models.

Analysis of the signalling mechanisms involved in Cell Wall Integrity maintenance in A.thaliana
Creators: name: McKenna, Joseph Francis
Publisher: name: Imperial College London
Year: 2013

description: The plant cell wall is a dynamic structure that has an integral role during plant development and responses to biotic and abiotic stresses. A cell wall integrity (CWI) maintenance mechanism in plants has been inferred. The aim of this study was to investigate the signalling mechanism that regulates the response of Arabidopsis thaliana to CWI impairment. Here I show that JA and SA levels increase after 3 and 5 hours (respectively) of CWI impairment. In order to determine the downstream functions of the different signalling mechanisms and their cross-talk upon CWI impairment; lignin deposition, JA & SA induction and root growth inhibition (RGI) phenotypes were used as downstream readouts. My results show that ROS are required for lignin deposition whereas JA & SA-based mechanisms are required to inhibit lignin deposition. ROS and JA act antagonistically to regulate downstream lignin deposition. In addition, a bi-phasic ROS-based signal is induced after CWI impairment, with the initial signal required for JA induction and the later signal required for inhibition of JA induction. H2O2 increased at the plasma membrane in the elongation zone of the root during CWI impairment, as determined by the genetically encoded probe HyPer. The functions of several RLKs in CWI maintenance were investigated. These included BAK1 and BIK1. Most of the mutant RLKs investigated affected one or two of the downstream readouts, highlighting the complexity of CWI signalling and demonstrating the involvement of elements of the innate immunity signalling. However, THE1 and XII7, mutant seedlings display altered responsiveness to all CWI impairment downstream readouts. These results suggest that these two RLKs represent key regulators of CWI maintenance. To summarise, the research piresented here has provided novel insights into the signalling mechanisms mediating the response to CWI impairment; has clarified the involvement of several RLKs whose functions had not been defined before and has shown that THE1 and XII7 are key regulators required for mediating all responses to CWI impairment.

description: In a stochastic process, noise often modifies the picture offered by the mean field dynamics. In particular, when there is an absorbing state, the noise erases a stable fixed point of the mean field equation from the stationary distribution, and turns it into a transient peak. We make a quantitative analysis of this effect for a simple genetic regulatory network with positive feedback, where the proteins become extinct in the presence of stochastic noise, contrary to the prediction of the deterministic rate equation that the protein number converges to a non-zero value. We show that the transient peak appears near the stable fixed point of the rate equation, and the extinction time diverges exponentially as the stochastic noise approaches zero. We also show how the baseline production from the inactive gene ameliorates the effect of the stochastic noise, and interpret the opposite effects of the noise and the baseline production in terms of the position shift of the unstable fixed point. The order of magnitude estimates using biological parameters suggest that for a real gene regulatory network, the stochastic noise is sufficiently small so that not only is the extinction time much larger than biologically relevant time-scales, but also the effect of the baseline production dominates over that of the stochastic noise, leading to the protection from the catastrophic rare event of protein extinction.

description: In this work we consider the role of muons in various URCA processes relevant for neutrino emissions in the core region of neutron stars. The calculations are done for $β$--stable nuclear matter with and without muons. We find muons to appear at densities $ρ= 0.15$ fm$^{-3}$, slightly around the saturation density for nuclear matter $ρ_0 =0.16$ fm$^{-3}$. The direct URCA processes for nucleons are forbidden for densities below $ρ= 0.5$ fm$^{-3}$, however the modified URCA processes with muons $(n+N\rightarrow p+N +μ+\overlineν_μ, p+N+μ\rightarrow n+N+ν_μ$), where $N$ is a nucleon, result in neutrino emissivities comparable to those from $(n+N\rightarrow p+N +e +\overlineν_e, p+N+e \rightarrow n+N+ν_e$). This opens up for further possibilities to explain the rapid cooling of neutrons stars. Superconducting protons reduce however these emissivities at densities below $0.4$ fm$^{-3}$.

description: We describe the specifications, characteristics, calibration, and analysis of data from the University of New South Wales Infrared Fabry-Perot (UNSWIRF) etalon. UNSWIRF is a near-infrared tunable imaging spectrometer, used primarily in conjunction with IRIS on the AAT, but suitable for use as a visitor instrument at other telescopes. The etalon delivers a resolving power in excess of 4000 (corresponding to a velocity resolution ~75 km/s), and allows imaging of fields up to 100" in diameter on the AAT at any wavelength between 1.5 and 2.4 microns for which suitable blocking filters are available.

description: The facilities designed to study collisions of relativistic nuclei, such as the MPD at NICA (JINR), STAR at RHIC (BNL), ALICE, ATLAS and CMS at the LHC (CERN), are equipped with pairs of hadronic Zero Degree Calorimeters (ZDC) to detect forward nucleons at the both sides of the interaction point and estimate the collision centrality. The energy deposited in a ZDC fluctuates from one event to another, but on average it is proportional to the number of absorbed nucleons. Forward nucleons are also emitted in electromagnetic dissociation (EMD) of nuclei in ultraperipheral collisions, and they are used to monitor the luminosity. As known, ZDC energy spectra are specific to each facility, because they are affected by the ZDC acceptance, and the ZDC energy resolution depends on the beam energy. In this work a simple combinatorial model leading to handy formulas has been proposed to connect the numbers of emitted and detected forward nucleons taking into account a limited ZDC acceptance. The ZDC energy spectra from the EMD with the emission of one, two, three and four forward neutrons and protons have been modeled for collision energies of NICA and the LHC. The case of a rather small ZDC acceptance has been investigated and a possibility to measure the inclusive nucleon emission cross section has been demonstrated.

Modelling single-phase fluid-fluid reactive transport at the pore-scale

description: Reactive transport is an important field of study in the earth sciences. It captures both natural phenomena, and industrial and environmental applications, including transport of pollutants in the subsurface, nuclear waste storage, and carbon storage. The aim of this thesis is to provide a better understanding of coupled physico-chemical processes governing these phenomena as well as to be used as tools for better understanding these environmental applications. We introduce from first principles a novel pore-scale modelling approach capable of simulating single-phase fluid-fluid reactive transport directly on voxels of 3D images of porous media constructed from X-ray tomography. We use a streamline-based particle tracking method for simulating flow and transport, while for reaction to occur, both reactants must be within a diffusive distance. We assign a probability of reaction, as a function of the reaction rate constant and the diffusion length. The model for reaction is validated against analytical solutions in a free fluid as well as against experimental data on reactive transport in porous media. It takes into account the degree of incomplete mixing present at the sub-pore level. We demonstrate the nature of dynamic changes in the reaction rate, which is related to the degree of pore-scale mixing. Our model does not use any calibrating parameters to fit empirical data unlike other models published in the literature. The model is then extended to investigate the impact of pore structure heterogeneity, transport, and reaction conditions on the overall reaction rate in porous media by studying different classes of porous media. The overall reaction rate varies significantly according to the degree of heterogeneity and transport conditions. It is found that the rate of reaction is a subtle combination of the amount of mixing and spreading that cannot be predicted from the dispersion coefficient alone. At low Péclet number, the effective reaction rate is principally controlled by the amount of mixing due to diffusion. On the other hand, at high Péclet number the reaction rate is controlled by a combination of pore-scale mixing due to spreading and the degree of heterogeneity of the pore structure.

description: We investigate the effects of fluctuations of the nuclear surface on the harmonic oscillator elastic charge form factor of light nuclei, while simultaneously approximating the short-range correlations through a Jastrow correlation ~factor. Inclusion of surface-fluctuation effects within this description, by truncating the cluster expansion at the two-body part, is found to improve somewhat the fit to the elastic charge form-factor of $^{16}O$ and $^{40}Ca$. However, the convergence of the cluster expansion is expected to deteriorate. An additional finding is that the surface-fluctuation correlations produce a drastic change in the asymptotic behavior of the point-proton form factor, which now falls off quite slowly (i.e. as $const. \cdot q^{-4}$) at large values of the momentum transfer $q$.
