description: One of the current issues in Brain-Computer Interface is how to deal with noisy Electroencephalography measurements organized as multidimensional datasets. On the other hand, recently, significant advances have been made in multidimensional signal completion algorithms that exploit tensor decomposition models to capture the intricate relationship among entries in a multidimensional signal. We propose to use tensor completion applied to EEG data for improving the classification performance in a motor imagery BCI system with corrupted measurements. Noisy measurements are considered as unknowns that are inferred from a tensor decomposition model. We evaluate the performance of four recently proposed tensor completion algorithms plus a simple interpolation strategy, first with random missing entries and then with missing samples constrained to have a specific structure (random missing channels), which is a more realistic assumption in BCI Applications. We measured the ability of these algorithms to reconstruct the tensor from observed data. Then, we tested the classification accuracy of imagined movement in a BCI experiment with missing samples. We show that for random missing entries, all tensor completion algorithms can recover missing samples increasing the classification performance compared to a simple interpolation approach. For the random missing channels case, we show that tensor completion algorithms help to reconstruct missing channels, significantly improving the accuracy in the classification of motor imagery, however, not at the same level as clean data. Tensor completion algorithms are useful in real BCI applications. The proposed strategy could allow using motor imagery BCI systems even when EEG data is highly affected by missing channels and/or samples, avoiding the need of new acquisitions in the calibration stage.

Influence of Viscosity Modifiers on Hydrodynamic Friction
Creators: name: Holtzinger, Jennifer
Publisher: name: Imperial College London
Year: 2011

description: Polymer additives, named Viscosity Modifiers (VMs), have been added to motor engine lubricants for more than 50 years, where they are used to increase the viscosity index of their blends. It is well known that solutions of VMs exhibit shear thinning under high strain rate conditions as are present in engine journal bearings. In the past, this shear thinning was regarded as undesirable since it might reduce hydrodynamic film thickness. However it has been reported that multigrade oils containing VMs provide lower engine friction than polymer-free oils of comparable viscosity and the most likely origin of this is a reduction of hydrodynamic friction due to temporary shear thinning of the polymer solutions. In this thesis, the role of polymer shear thinning in reducing hydrodynamic friction is clarified by the experimental work carried out on a range of different polymer types. This study includes the viscosity measurements over a wide range of shear rate and also friction and film thickness analyses performed in a soft elastohydrodynamic lubrication contact in order to avoid piezoviscous effects. A very recent technique based on laser induced fluorescence technology is used to evaluate the film thickness. These experimental results are compared with theoretical calculations, which allows based on the rheological data of each polymer solution, the impact of polymer shear thinning on hydrodynamic friction to be quantified. The studied polymer solutions show a decrease in film thickness and in hydrodynamic friction compared to Newtonian fluids of similar viscosity. This reduction is ascribed to the temporary shear thinning of polymer blends. The proposed theoretical models show good agreement with the experimental values. They appear to be useful tools to quantify the impact of polymer shear thinning on film thickness and friction. In addition to this main work, the polymer solutions are analysed under high contact pressure and the shear stability of some commercials viscosity modifiers are studied. A new method is developed to quantify the permanent viscosity loss of each polymer solution and this is compared to the industrial Kurt-Orbahn test.

description: We study the Casimir effect for scalar fields with general curvature coupling subject to mixed boundary conditions $(1+β_{m}n^μ\partial_μ)ϕ=0$ at $x=a_{m}$ on one ($m=1$) and two ($m=1,2$) parallel plates at a distance $a\equiv a_{2}-a_{1}$ from each other. Making use of the generalized Abel-Plana formula previously established by one of the authors \cite{Sahrev}, the Casimir energy densities are obtained as functions of $β_{1}$ and of $β_{1}$,$β_{2}$,$a$, respectively. In the case of two parallel plates, a decomposition of the total Casimir energy into volumic and superficial contributions is provided. The possibility of finding a vanishing energy for particular parameter choices is shown, and the existence of a minimum to the surface part is also observed. We show that there is a region in the space of parameters defining the boundary conditions in which the Casimir forces are repulsive for small distances and attractive for large distances. This yields to an interesting possibility for stabilizing the distance between the plates by using the vacuum forces.

description: We study supersymmetric solutions within seven-dimensional $N=2$ gauged supergravity coupled to three vector multiplets in seven dimensions. The gauged supergravity contains six vector fields that gauge the $SO(4)\sim SO(3)\times SO(3)$ symmetry and admits two $N=2$ supersymmetric $AdS_7$ vacua with $SO(4)$ and $SO(3)_{\textrm{diag}}\subset SO(3)\times SO(3)$ symmetries. We consider solutions interpolating between two asymptotically locally $AdS_7$ geometries in the presence of a three-form field. For a particular value of the two $SO(3)$ gauge coupling constants, the $SO(3)_{\textrm{diag}}$ supersymmetric $AdS_7$ vacuum does not exist, but the solutions can be uplifted to eleven dimensions by a known reduction ansatz. We also study solutions of this type and their embedding in M-theory. We further extend these solutions to include the $SO(3)_{\textrm{diag}}$ gauge fields and argue that, in general, this generalization does not lead to supersymmetric solutions.

description: We calculate the Legendre expansion of the rate of the process $ν+ \barν \leftrightarrow e^+ + e^-$ up to 3rd order extending previous results of other authors which only consider the 0th and 1st order terms. Using different closure relations for the moment equations of the radiative transfer equation we discuss the physical implications of taking into account quadratic and cubic terms on the energy deposition outside the neutrinosphere in a simplified model. The main conclusion is that 2nd order is necessary in the semi-transparent region and gives good results if an appropriate closure relation is used.

On a continuation of quaternionic and octonionic logarithm along curves and the winding number

description: This paper focuses on the problem of finding a continuous extension of the hypercomplex logarithm along a path. While a branch of the complex logarithm can be defined in a small open neighbourhood of a strictly negative real point, no continuous branch of the hypercomplex logarithm can be defined in any open set $A\subset \mathbb K\setminus \{0\}$ which contains a strictly negative real point $x_0$ (here $\mathbb K$ represents the algebra of quaternions or octonions).
 To overcome these difficulties, we introduced the logarithmic manifold $\mathscr E_\mathbb K^+$ and then showed that if $q\in\mathbb K,\ q=x+Iy$ then $E(x+Iy) %= (\exp (x + Iy), Iy) = (\exp x \cos y + I\exp x \sin y, Iy)$ is an immersion and a diffeomorphism between $\mathbb K$ and $\mathscr E_\mathbb K^+$.
 In this paper, we consider lifts of paths in $\mathbb K\setminus\{0\}$ to the logarithmic manifold $\mathscr{E}^+_\mathbb K$; even though $\mathbb K \setminus \{0\}$ is simply connected, in general, given a path in $\mathbb K \setminus \{0\}$, the existence of a lift of this path to $\mathscr{E}^+_\mathbb K$ is not guaranteed. There is an obvious equivalence between the problem of lifting a path in $\mathbb K \setminus \{0\}$ and the one of finding a continuation of the hypercomplex logarithm $\log_{\mathbb K}$ along this path.

description: We describe a method for determining the limb polarization and limb darkening of stars in eclipsing binary systems, by inverting photometric and polarimetric light curves. Because of the ill-conditioning of the problem, we use the Backus-Gilbert method to control the resolution and stability of the recovered solution, and to make quantitative estimates of the maximum accuracy possible. Using this method we confirm that the limb polarization can indeed be recovered, and demonstrate this with simulated data, thus determining the level of observational accuracy required to achieve a given accuracy of reconstruction. This allows us to set out an optimal observational strategy, and to critcally assess the claimed detection of limb polarization in the Algol system. The use of polarization in stars has been proposed as a diagnostic tool in microlensing surveys by Simmons et al. (1995), and we discuss the extension of this work to the case of microlensing of extended sources.

Modelling the freezing behaviour of ITS-90 metal fixed points for better understanding of the influence of impurities and thermal effects
Creators: name: Malik, Zohaib
Publisher: name: Imperial College London
Year: 2011

description: The methods currently used by metrologists for estimating the influence of impurities in metal fixed points require accurate knowledge of the concentrations of impurities present and of liquidus slopes of binary systems. In this thesis, two alternative methods are presented that can estimate the influence of impurities without requiring any knowledge of the impurities. Both methods are based on Scheil’s solidification model. By using a numerical solidification model it is shown that the freezing behaviour of a fixed point cell can approximate to Scheil’s model when the freezing time is greater than x2 / D, where x is the thickness of the ingot and D is the diffusion coefficient of impurities in the liquid. The first method uses the gradient of a freezing curve at about 0.5 fraction solid, and is able to predict the influence of impurities with a maximum uncertainty of around 25%. This is assuming that all the important impurities have distribution coefficients much lower than 1, which is often the case in practice. By applying some modifications to this method, it is possible to determine whether or not the distribution coefficients of the dominant impurities lie below or above 1. The second method involves numerically best fitting Scheil’s equation to a freezing curve. This method works for materials with multiple impurities, but problems arise when it is applied to an experimental freezing curve due to distortion in the freeze plateau. This is thought to be caused by the thermal effects arising from the non-uniform thermal conditions under which the fixed point is realised. It is experimentally and numerically demonstrated that the thermal uniformity of the three-zone furnace is improved by separating (thermally isolating) the heating zones. By modelling the freezing behaviour of a silver cell in the three-zone furnace it is shown that (a) increasing the freeze undercooling increases the influence of the thermal effects and adversely affects the shape of the freeze plateau, and (b) making the temperature at the base of the cell higher than that at the top reduces the influence of the thermal effects and improves the shape of the freeze plateau.

description: We improve reliable, long-horizon, goal-directed navigation in partially-mapped environments by using non-locally available information to predict the goodness of temporally-extended actions that enter unseen space. Making predictions about where to navigate in general requires non-local information: any observations the robot has seen so far may provide information about the goodness of a particular direction of travel. Building on recent work in learning-augmented model-based planning under uncertainty, we present an approach that can both rely on non-local information to make predictions (via a graph neural network) and is reliable by design: it will always reach its goal, even when learning does not provide accurate predictions. We conduct experiments in three simulated environments in which non-local information is needed to perform well. In our large scale university building environment, generated from real-world floorplans to the scale, we demonstrate a 9.3\% reduction in cost-to-go compared to a non-learned baseline and a 14.9\% reduction compared to a learning-informed planner that can only use local information to inform its predictions.

The mirror partner of singular Calabi-Yau with a shrinking del Pezzo four-cycle is described as the affine 7-brane backgrounds probed by a D3-brane. Evaluating the mirror map and the BPS central charge we relate junction charges to RR charges of D-branes wrapped on del Pezzo surfaces. This enables us to determine how the string junctions are mapped to D-branes on del Pezzo surfaces.

In a simple model for one complex field an expansion in the parameters describing the relative position of two vortices can be given in terms of trigonometric and exponential functions. The results are then compared to those of the Ginzburg-Landau theory of a superconductor in a magnetic field at the point between type-I and type-II superconductivity. For the angular dependence a similar pattern emerges in both models. The differences for the radial functions are studied up to third order.

description: We present a machine learning (ML) method for predicting electronic structure correlation energies using Hartree-Fock input.The total correlation energy is expressed in terms of individual and pair contributions from occupied molecular orbitals, and Gaussian process regression is used to predict these contributions from a feature set that is based on molecular orbital properties, such as Fock, Coulomb, and exchange matrix elements. With the aim of maximizing transferability across chemical systems and compactness of the feature set, we avoid the usual specification of ML features in terms of atom- or geometry-specific information, such atom/element-types, bond-types, or local molecular structure. ML predictions of MP2 and CCSD energies are presented for a range of systems, demonstrating that the method maintains accuracy while providing transferability both within and across chemical families; this includes predictions for molecules with atom-types and elements that are not included in the training set. The method holds promise both in its current form and as a proof-of-principle for the use of ML in the design of generalized density-matrix functionals.

Distance bounding and Heegaard Floer homology methods in reducible Dehn surgery
Creators: name: Mauricio, Mauro
Publisher: name: Imperial College London
Year: 2012

description: Motivated by the formation of certain link types during Hin-mediated DNA recombination experiments, we consider tangle equations where one of the products is a connect-sum of 2-bridge links. We are thus led to study Dehn surgeries on knots in lens spaces that yield connect-sums of lens spaces. Using 3-manifold methods, we prove, for certain classes of knot exteriors, a distance bound on Dehn surgery slopes. (This proof complements an algebraic-geometric proof of a more general statement due to Boyer and Zhang [6]). Analysing the known examples of connect-sums of lens spaces surgeries, together with some sample calculations, we conjecture that if surgery on a knot K [Symbol appears here. To view, please open pdf attachment] L(p, q), with p, q [Symbol appears here. To view, please open pdf attachment]1, 2, yields L(p, q)#L(t, 1), then the knot has reducible exterior. Using Heegaard Floer homology, we prove a special case of the conjecture, as well as some surgery obstructions. We then apply our results, in the spirit of the tangle model of Ernst and Sumners [67], to the problem of Hin-mediated DNA recombination, where we characterise its distributive recombination step.
Finite Simple Subgroups of Exceptional Algebraic Groups
Creators: name: Litterick, Alastair
Publisher: name: Imperial College London
Year: 2013

description: Let G = G(K) be a simple algebraic group over an algebraically closed field K of characteristic p ­­≥ 0. The study of subgroups of G splits naturally according to whether G is of classical or exceptional type, and according to whether the subgroups considered are finite or of positive dimension. This thesis considers finite subgroups of adjoint groups G of exceptional type. A finite subgroup of G is called Lie primitive if it lies in no proper, closed subgroup of positive dimension. This is a natural maximality condition and, when studying Lie primitive subgroups, a reduction theorem due to Borovik allows us to focus on those whose socle is a non-abelian finite simple group. The study then splits again according to whether or not this socle is a member of Lie(p), the simple groups of Lie type in characteristic p. For H = H(q) ∈ Lie(p), in [LS98b] Liebeck and Seitz prove, for all but finitely many q, that G cannot have a Lie primitive subgroup with socle H unless G and H are of the same Lie type. For H ∉ Lie(p), in [LS99] Liebeck and Seitz produce a complete (finite) list of those H which embed into an adjoint exceptional simple algebraic group, though conjugacy and Lie primitivity remain largely open. The first result of this thesis is to disprove the existence of Lie primitive embeddings of many simple groups H ∉ Lie(p). For example, for n ≥ 10 the alternating group Altn has no Lie primitive embeddings into an adjoint exceptional algebraic group, in any characteristic. This has implications for the subgroup structure of the nite groups of Lie type. In particular, it is deduced here that for n ≥ 11 the groups Altn and Symn never occur as a maximal subgroup of any nite almost-simple group of exceptional Lie type.

description: We report on results of recent, high resolution hydrodynamic simulations of the formation and evolution of X-ray clusters of galaxies carried out within a cosmological framework. We employ the highly accurate piecewise parabolic method (PPM) on fixed and adaptive meshes which allow us to resolve the flow field in the intracluster gas. The excellent shock capturing and low numerical viscosity of PPM represent a substantial advance over previous studies using SPH. We find that in flat, hierarchical cosmological models, the ICM is in a turbulent state long after turbulence generated by the last major merger should have decayed away. Turbulent velocites are found to vary slowly with cluster radius, being $\sim 25%$ of $σ_{vir}$ in the core, increasing to $\sim 60%$ at the virial radius. We argue that more frequent minor mergers maintain the high level of turbulence found in the core where dynamical times are short. Turbulent pressure support is thus significant throughout the cluster, and results in a somewhat cooler cluster ($T/T_{vir} \sim .8$) for its mass. Some implications of cluster turbulence are discussed.

description: Quantum mechanical few-body systems in reduced dimensionalities can exhibit many interesting properties such as scale-invariance and universality. Analytical descriptions are often available for integer dimensionality, however, numerical approaches are necessary for addressing dimensional transitions. The Fully-Correlated Gaussian method provides a variational description of the few-body real-space wavefunction. By placing the particles in a harmonic trap, the system can be described at various degrees of anisotropy by squeezing the confinement. Through this approach, configurations of two and three identical bosons as well as heteronuclear (Cs-Cs-Li and K-K-Rb) systems are described during a continuous deformation from three to one dimension. We find that the changes in binding energies between integer dimensional cases exhibit a universal behavior akin to that seen in avoided crossings or Zeldovich rearrangement.

description: The neutralization of low energy Na$^+$ and Li$^+$ ions scattered from Au nanoclusters formed by deposition onto oxide surfaces decreases as the cluster size increases. An explanation for this behavior is provided here, which is based on the notion that the atoms in the clusters are not uniformly charged, but that the edge atoms are positively charged while the center atoms are nearly neutral. This leads to upward pointing dipoles at the edge atoms that increase the neutralization probability of alkali ions scattered from those atoms. As the clusters increase in size, the number of edge atoms relative to the number of center atoms decreases, so that that the average neutralization also decreases. Calculations employing this model are compared to experimental data and indicate good agreement if the strengths of the dipoles at the edge atoms are assumed to decrease with cluster size. This model also explains differences in the neutralization probabilities of scattered Na$^+$ and Li$^+$.

description: Many populations of animals or plants, exhibit a metapopulation structure with close, spatially-separated subpopulations. The field of metapopulation theory has made significant advancements since the influential Levins model. Various modeling approaches have provided valuable insights to theoretical Ecology. Despite extensive research on metapopulation models, there are still challenging questions that are difficult to answer from ecological metapopulational data or multi-patch models. Low-dimension mathematical models offer a promising avenue to address these questions, especially for global dynamics which have been scarcely investigated. In this study, we investigate a two-patch metapopulation model with logistic growth and diffusion between patches. By using analytical and numerical methods, we thoroughly analyze the impact of diffusion on the dynamics of the metapopulation. We identify the equilibrium points and assess their local and global stability. Furthermore, we analytically derive the optimal diffusion rate that leads to the highest metapopulation values. Our findings demonstrate that increased diffusion plays a crucial role in the preservation of both subpopulations and the full metapopulation, especially under the presence of stochastic perturbations. Specifically, at low diffusion values, the origin is a repeller, causing orbits starting around it to travel closely parallel to the axes. This configuration makes the metapopulation less resilient and thus more susceptible to local and global extinctions. However, as diffusion increases, the repeller transitions to a saddle point, and orbits starting near the origin rapidly converge to the unstable manifold of the saddle. This phenomenon reduces the likelihood of stochastic extinctions and the metapopulation becomes more resilient due to these changes in the vector field of the phase space.

Transverse Laser Cooling of SrF
Creators: name: Matsushima, Aki
Publisher: name: Imperial College London
Year: 2013

description: This thesis discusses an experiment, which has demonstrated transverse laser cooling of a pulsed supersonic beam of strontium monofluoride (SrF) molecules. Producing ultracold molecules is important because they could advance many fields including many-body physics, quantum chemistry and precision measurements to explore fundamental forces in nature. Direct laser cooling of molecules is a new and promising way to produce molecules with temperatures in the sub-millikelvin range. In the experiment, SrF molecules produced from a pulsed supersonic source were cooled in the transverse direction using light from just two lasers. The molecular beam brightness was increased by about 20%. I discuss the detailed experimental setup, laser system and data analysis. I also present several theoretical models, which give insight into the cooling experiment. Finally, I discuss improvements to this experiment, which should enable higher yields of ultracold molecules to be produced.
Non-canonical folding of Dynkin diagrams and reduction of affine Toda theories

description: The equation of motion of affine Toda field theory is a coupled equation for $r$ fields, $r$ is the rank of the underlying Lie algebra. Most of the theories admit reduction, in which the equation is satisfied by fewer than $r$ fields. The reductions in the existing literature are achieved by identifying (folding) the points in the Dynkin diagrams which are connected by symmetry (automorphism). In this paper we present many new reductions. In other words the symmetry of affine Dynkin diagrams could be extended and it leads to non-canonical foldings. We investigate these reductions in detail and formulate general rules for possible reductions. We will show that eventually most of the theories end up in $a_{2n}^{(2)}$ that is the theory cannot have a further dimension $m$ reduction where $m

description: In this paper, we study the large $n$ asymptotics of the expected maximum of an $n$-step random walk/Lévy flight (characterized by a Lévy index $10$, the asymptotic expansion of the expected maximum is simply related to the one for $c<0$ by adding to the latter the linear drift term $cn$, making the leading term grow linearly for large $n$, as expected. Finally, we derive a scaling form interpolating smoothly between the cases $c=0$ and $c\ne 0$. These results are borne out by numerical simulations in excellent agreement with our analytical predictions.

ASCA spectroscopy of the luminous infrared galaxy NGC6240: X-ray emission from a starburst and a buried active nucleus

Publisher: name: arXiv

description: We present an X-ray spectral study of the prototype far-infrared galaxy NGC6240 from ASCA. The soft X-ray spectrum (below 2 keV) shows clear signatures of thermal emission well described with a multi-temperature optically-thin plasma, which probably originates in a powerful starburst. Strong hard X-ray emission is also detected with ASCA and its spectrum above 3 keV is extremely flat with a prominent iron K line complex, very similar to that seen in the Seyfert 2 galaxy NGC1068 but about an order of magnitude more luminous [L(3-10keV)=1.4E42 erg/s]. The hard X-ray spectrum indicates that only reflected X-rays of an active galactic nucleus (AGN) buried in a heavy obscuration [N(H)>2E24 cm-2] are visible. This is evidence for an AGN in NGC6240 emitting possibly at a quasar luminosity and suggests its significant contribution to the far-infrared luminosity.

Binding a Hopfion in Chiral Magnet Nanodisk

description: Hopfions are three-dimensional (3D) topological textures characterized by the integer Hopf invariant $Q_H$. Here, we present the realization of a zero--field, stable hopfion spin texture in a magnetic system consisting of a chiral magnet nanodisk sandwiched by two films with perpendicular magnetic anisotropy. The preimages of the spin texture and numerical calculations of $Q_H$ show that the hopfion has $Q_H=1$. Furthermore, another non-trivial state that includes a monopole--antimonopole pair (MAP) is also stabilized in this system. By applying an external magnetic field, hopfion and MAP states with the same polarization can be switched between each other. The topological transition between the hopfion and the MAP state involves a creation (annihilation) of the MAP and twist of the preimages. Our work paves the way to study non-trivial 3D topological spin textures and stimulates more investigations in the field of 3D spintronics.

The unifying formula is expected to be of great use in applied mathematics. Some applications of the formula are given for illustration.

description: R. Hirota and K. Kimura discovered integrable discretizations of the Euler and the Lagrange tops, given by birational maps. Their method is a specialization to the integrable context of a general discretization scheme introduced by W. Kahan and applicable to any vector field with a quadratic dependence on phase variables. We report several novel observations regarding integrability of the Kahan-Hirota-Kimura discretization. For several of the most complicated cases for which integrability is known (Clebsch system, Kirchhoff system, and Lagrange top), - we give nice compact formulas for some of the more complicated integrals of motion and for the density of the invariant measure, and - we establish the existence of higher order Wronskian Hirota-Kimura bases, generating the full set of integrals of motion. While the first set of results admits nice algebraic proofs, the second one relies on computer algebra.
