description: We study the elastic scattering of the lightest neutralino with a nucleus in the framework of the minimal supersymmetric standard model (MSSM) with explicit flavor preserving CP violation, including the one-loop CP-violating neutral Higgs-boson mixing effects induced dominantly by the CP phases in the top and bottom (s)quark sectors. We construct the most general form of the effective Lagrangian for the neutralino-nucleus scattering in the limit of vanishing momentum transfers and then we perform a comprehensive analysis of the effects of the complex CP phases on the mass spectra of the lightest neutralino, neutral Higgs bosons and top squarks, and on the the spin-dependent and spin-independent neutralino-nucleus scattering cross section for three neucleus targets F, Si and Ge. The CP phases can reduce or enhance the neutralino-nucleus cross sections significantly, depending on the values of the real parameters in the MSSM.

Adaptive Response System for Distributed Denial-of-Service Attacks
Creators: name: Thing, Vrizlynn Ling Ling
Publisher: name: Imperial College London
Year: 2008

description: The continued prevalence and severe damaging effects of the Distributed Denial of Service (DDoS) attacks in today’s Internet raise growing security concerns and call for an immediate response to come up with better solutions to tackle DDoS attacks. The current DDoS prevention mechanisms are usually inflexible and determined attackers with knowledge of these mechanisms, could work around them. Most existing detection and response mechanisms are standalone systems which do not rely on adaptive updates to mitigate attacks. As different responses vary in their “leniency” in treating detected attack traffic, there is a need for an Adaptive Response System. We designed and implemented our DDoS Adaptive ResponsE (DARE) System, which is a distributed DDoS mitigation system capable of executing appropriate detection and mitigation responses automatically and adaptively according to the attacks. It supports easy integrations for both signature-based and anomaly-based detection modules. Additionally, the design of DARE’s individual components takes into consideration the strengths and weaknesses of existing defence mechanisms, and the characteristics and possible future mutations of DDoS attacks. These components consist of an Enhanced TCP SYN Attack Detector and Bloom-based Filter, a DDoS Flooding Attack Detector and Flow Identifier, and a Non Intrusive IP Traceback mechanism. The components work together interactively to adapt the detections and responses in accordance to the attack types. Experiments conducted on DARE show that the attack detection and mitigation are successfully completed within seconds, with about 60% to 86% of the attack traffic being dropped, while availability for legitimate and new legitimate requests is maintained. DARE is able to detect and trigger appropriate responses in accordance to the attacks being launched with high accuracy, effectiveness and efficiency. We also designed and implemented a Traffic Redirection Attack Protection System (TRAPS), a stand-alone DDoS attack detection and mitigation system for IPv6 networks. In TRAPS, the victim under attack verifies the authenticity of the source by performing virtual relocations to differentiate the legitimate traffic from the attack traffic. TRAPS requires minimal deployment effort and does not require modifications to the Internet infrastructure due to its incorporation of the Mobile IPv6 protocol. Experiments to test the feasibility of TRAPS were carried out in a testbed environment to verify that it would work with the existing Mobile IPv6 implementation. It was observed that the operations of each module were functioning correctly and TRAPS was able to successfully mitigate an attack launched with spoofed source IP addresses.
Controlled Low-Strength Materials Containing Solid Waste from Minerals Bioleaching
Creators: name: Bouzalakos, Steve
Publisher: name: Imperial College London
Year: 2008

description: Sustainable treatment and disposal of mine waste is a serious environmental issue faced by the mining industry worldwide. Conventional methods of mine waste management predominantly involve indefinite retention in engineered tailings dams. The cost and liability of such surface storage facilities have increased significantly in recent years as an outcome of stringent environmental legislation and mine closure requirements gradually transforming the economics of mine waste disposal. Backfill methods, particularly cemented paste backfill, are increasingly perceived as sustainable, environmentally friendly and cost-effective alternatives as they put waste material to practical use. Controlled low-strength materials (CLSM) offer an effective and practical alternative to similar analogues – requiring minimal compaction, being self-levelling and excavatable in the future if necessary. The aim of this research was to develop and evaluate CLSM, previously un-tested at mines, in which novel utilisation of bioleach waste is maximised and Portland cement content minimised while satisfying performance requirements for classification as CLSM. Leachability of toxic substances was minimised through encapsulating CLSM within a coating of relatively inert CLSM. Formulation and optimisation of CLSM using statistical mixture design and response surface analysis has ensured proper understanding of component interactions and influence on mechanical strength with a minimum amount of experiments. Optimised CLSM formulations were tested for their mechanical, physical, micro-structural, mineralogical and chemical properties. Effects of encapsulation were determined by assessing chemical leaching. The work indicated that bioleach waste could be beneficially reformed as CLSM of appropriate compressive strength for application in groundwork as loadbearing materials. Porosity and hydraulic conductivity were correspondingly high. Leachability of arsenic, barium, chromium, lead and zinc was significant (levels varied depending on waste type). Encapsulation significantly reduced leachability indicating promising potential for implementation of this technology in the mining industry. The research presented in this thesis substantiated the need for, and potential of, sustainable novel alternative technologies such as CLSM to augment future waste management strategies in the mining industry via safe emplacement of solid bioleach waste in the sub-surface.
Analytical results for the in-degree and out-degree distributions of directed random networks that grow by node duplication

description: We present exact results for the degree distribution in a directed network model that grows by node duplication (ND). Such models are useful in the study of the structure and growth dynamics of gene regulatory networks and scientific citation networks. Starting from an initial seed network, at each time step a random node, a mother node, is selected for duplication. Its daughter node is added to the network and duplicates each outgoing link of the mother node with probability p. In addition, the daughter node forms a directed link to the mother node itself. We obtain analytical results for the in-degree distribution $P_t(K_{in}=k)$, and for the out-degree distribution $P_t(K_{out}=k)$ at time t. The in-degrees follow a shifted power-law, so the network is asymptotically scale free. In contrast, the out-degree distribution is narrow, and converges to a Poisson distribution in the sparse network limit and to a Gaussian distribution in the dense network limit. Such distinction between a broad in-degree distribution and a narrow out-degree distribution is common in empirical networks such as scientific citation networks. Using this we calculate the mean degree $\langle K_{in}\rangle_t=\langle K_{out}\rangle_t$, which converges to $1/(1-p)$ in the large network limit, for the whole range of $01/2$ the mean degree diverges in the large network limit. We also present analytical results for the distribution of the number of upstream and downstream nodes from a random node. The mean values $\langle N_{up}\rangle_t=\langle N_{down}\rangle_t$ scale logarithmically with the network size, implying that only a small fraction of pairs of nodes are connected by directed paths, unlike the undirected ND case that consists of a single component, hence not a small-world network.

description: Evaluating on adversarial examples has become a standard procedure to measure robustness of deep learning models. Due to the difficulty of creating white-box adversarial examples for discrete text input, most analyses of the robustness of NLP models have been done through black-box adversarial examples. We investigate adversarial examples for character-level neural machine translation (NMT), and contrast black-box adversaries with a novel white-box adversary, which employs differentiable string-edit operations to rank adversarial changes. We propose two novel types of attacks which aim to remove or change a word in a translation, rather than simply break the NMT. We demonstrate that white-box adversarial examples are significantly stronger than their black-box counterparts in different attack scenarios, which show more serious vulnerabilities than previously known. In addition, after performing adversarial training, which takes only 3 times longer than regular training, we can improve the model's robustness significantly.

description: A country's research success can be assessed from the power law function that links country and world rank numbers when publications are ordered by their number of citations; a similar function describes the distribution of country papers in world percentiles. These functions allow calculating the ep index and the probability of publishing highly cited papers, which measure the efficiency of the research system and the ability of achieving important discoveries or scientific breakthroughs, respectively. The aim of this paper was to use these metrics and other parameters derived from the percentile-based power law function to investigate research success in the USA, the EU, and other countries in hot medical, biochemical, and biotechnological topics. The results show that, in the investigated fields, the USA is scientifically ahead of all countries and that its research is likely to produce approximately 80% of the important global breakthroughs in the research topics investigated in this study. EU research has maintained a constant weak position with reference to USA research over the last 30 years.

description: In this dissertation the waste incineration process has been described, an overview of the state of the art control methodologies given and a new approach, based on input/output linearization and extremum seeking has been presented. This approach has been tested on a model appositely designed. The results have shown that it is possible to control the waste bed temperature to certain reference values, with robustness against changes in the waste composition. It is furthermore possible to identify reference values for the waste bed temperature such as the steam ow rate is maximized, while at the same time fulfilling operational constraints.

The calculations are performed in the infrared safe Yennie gauge. The discrepancy between two previous numerical calculations of these corrections existing in the literature is resolved. Our new result eliminates the largest source of the theoretical uncertainty in the magnitude of the deuterium-hydrogen isotope shift.

description: The scale of a phenomenologically successful charge-symmetry-violating nucleon-nucleon interaction, that attributed to meson exchange with a $ΔI =1$ rho-omega transition, is set by the Coleman-Glashow SU(2) breaking tadpole mechanism. A single tadpole scale has been obtained from symmetry arguments, electromagnetic meson and baryon measured mass splittings, and the observed isospin violating ($ΔI=1$) decay $ω\to π^+π^-$. The hadronic realization of this tadpole mechanism lies in the $I = 1$ $a_0$ scalar meson. We show that measured hadronic and two-photon widths of the $a_0$ meson, with the aid of the Vector Meson Dominance model, recover the universal Coleman-Glashow tadpole scale.

Deconfining Phase Transition in QCD_4 and QED_4 at Finite Temperature

description: We investigate the deconfining phase transition in QCD_4 and QED_4 at finite temperature using a perturbative deformation of topological quantum field theory (TQFT). A modified maximal abelian gauge (MAG) is utilized in the analysis. In this case, we can derive the linear potential studying the 2D theory through Parisi-Sourlas (PS) dimensional reduction. The mechanism of deconfining phase transition is proposed. It is geometrical to discuss the thermal effect on the linear potential. All we have to do is to investigate the behavior of topological objects as such instantons and vortices on a cylinder. This is the great advantage of our scenario. This mechanism is also applied in the case of QED_4. The phase structure at the high temperature of QED is investigated using the Coulomb potential on a cylinder. It coincides with the result in the lattice compact U(1) gauge theory. Also, QCD with MAG has the property called the abelian dominance, which enables us to discuss the deconfinement of QCD_4.

description: Surface plasmon polaritons in graphene couple strongly to surface phonons in polar substrates leading to hybridized surface plasmon-phonon polaritons (SPPPs). We demonstrate that a surface acoustic wave (SAW) can be used to launch propagating SPPPs in graphene/h-BN heterostructures on a piezoelectric substrate like AlN, where the SAW-induced surface modulation acts as a dynamic diffraction grating. The efficiency of the light coupling is greatly enhanced by the introduction of the h-BN film as compared to the bare graphene/AlN system. The h-BN interlayer not only significantly changes the dispersion of the SPPPs but also enhances their lifetime. The strengthening of the SPPPs is shown to be related to both the higher carrier mobility induced in graphene and the coupling with h-BN and AlN surface phonons. In addition to surface phonons, hyperbolic phonons appear in the case of multilayer h-BN films leading to hybridized hyperbolic plasmon-phonon polaritons (HPPPs) that are also mediated by the SAW. These results pave the way for engineering SAW-based graphene/h-BN plasmonic devices and metamaterials covering the mid-IR to THz range.

Liquidity risk and its measurement: modelling, analysis and computation
Creators: name: Capper, Yukun
Publisher: name: Imperial College London
Year: 2009

description: The recent turbulence in financial markets, of which a famous casualty is the collapse of the Long Term Capital Management hedge fund, has made market liquidity an issue of high concern to investors and risk managers. The latter group in particular realised that financial models, based on the assumption of perfectly liquid markets where investors can trade large amounts of assets without affecting their prices, may fail miserably under the circumstance where market liquidity vanishes. Understanding the robustness and reliability of models used for trading and risk management purposes is therefore crucially important in the risk analysis. Part I of this thesis studies liquidity risk and its measurement via mean reversion jump diffusion processes. An efficient Monte Carlo method is suggested to find approximate VaR and CVaR for all percentiles with one set of samples from the loss distribution, which applies to portfolios of securities as well as single security. Part II investigates the computational efficiency and flexibility of application of the FFT-based option pricing methodologies. First, an empirical testing of alternative twofactor stochastic volatility affine jump-diffusion models is conducted against an extensive S&P 500 index options data set, using a nonlinear ordinary least squares estimation framework. It is then shown how the two-dimensional FFT may be applied for the pricing of spread options, which have payoff functions and exercise regions that are nonlinear in the underlying log-asset prices. Furthermore, a non-affine four-factor stochastic volatility diffusion model is considered and an approximate CCF specification derived.

Finally, the predictions of the model for neutrino masses and mixing are discussed. The most predictive version of the model naturally fits atmospheric neutrino data with maximal $ν_μ\longrightarrow ν_τ$ oscillations and solar neutrino data with small mixing angle MSW $ν_e \longrightarrow ν_{sterile}$ oscillations.

Applying information theory to efficient SLAM
Creators: name: Chli, Margarita
Publisher: name: Imperial College London
Year: 2009

description: The problem of autonomous navigation of a mobile device is at the heart of the more general issue of spatial awareness and is now a well-studied problem in the robotics community. Following a plethora of approaches throughout the history of this research, recently, implementations have been converging towards vision-based methods. While the primary reason for this success is the enormous amount of information content encrypted in images, this is also the main obstacle in achieving faster and better solutions. The growing demand for high-performance systems able to run on affordable hardware pushes algorithms to the limits, imposing the need for more effective approximations within the estimation process. The biggest challenge lies in achieving a balance between two competing goals: the optimisation of time complexity and the preservation of the desired precision levels. The key is in agile manipulation of data, which is the main idea explored in this thesis. Exploiting the power of probabilistic priors in sequential tracking, we conduct a theoretical investigation of the information encoded in measurements and estimates, which provides a deep understanding of the map structure as perceived through the camera lens. Employing information theoretic principles to guide the decisions made throughout the estimation process we demonstrate how this methodology can boost both the efficiency and consistency of algorithms. Focusing on the most challenging processes in a state of the art system, we apply our information theoretic framework to local motion estimation and maintenance of large probabilistic maps. Our investigation gives rise to dynamic algorithms for quality map-partitioning and robust feature mapping in the presence of significant ambiguity and variable camera dynamics. The latter is further explored to achieve scalable performance allowing dense feature matching based on concrete probabilistic decisions.

description: The Jones eigenvalue problem first described by D.S. Jones in 1983 concerns unusual modes in bounded elastic bodies: time-harmonic displacements whose tractions and normal components are both identically zero on the boundary. This problem is usually associated with a lack of unique solvability for certain models of fluid-structure interaction. The boundary conditions in this problem appear, at first glance, to rule out {\it any} non-trivial modes unless the domain possesses significant geometric symmetries. Indeed, Jones modes were shown to not be possible in most $C^\infty$ domains (see article by T. Hargé 1990). However, we should in this paper that while the existence of Jones modes sensitively depends on the domain geometry, such modes {\it do} exist in a broad class of domains. This paper presents the first detailed theoretical and computational investigation of this eigenvalue problem in Lipschitz domains. We also analytically demonstrate Jones modes on some simple geometries.

description: After giving a pedagogical review of the chiral gauge approach to 2D gravity, with particular emphasis on the derivation of the gravitational Ward identities, we discuss in some detail the interpretation of matter correlation functions coupled to gravity in chiral gauge. We argue that in chiral gauge no {\it explicit} gravitational dressing factor, analogue to the Liouville exponential in conformal gauge, is necessary for left-right symmetric matter operators. In particular, we examine the gravitationally dressed four-point correlation function of products of left and right fermions. We solve the corresponding gravitational Ward identity exactly: in the presence of gravity this four-point function exhibits a logarithmic short-distance singularity, instead of the power-law singularity in the absence of gravity. This rather surprising effect is non-perturbative in the gravitational coupling and is a sign for logarithms in the gravitationally dressed operator product expansions. We also discuss some perturbative evidence that the chiral Gross-Neveu model may remain integrable when coupled to gravity.

description: Properties of excited baryonic states are investigated in the context of electroproduction of baryon resonances off the deuteron. In particular, the hadronic radii and the compositeness of baryon resonances are studied for kinematic situations in which their hadronic reinteraction is the dominant contribution. Specifically, we study the reaction $d(e,e'S_{11})N$ at $Q^2\ge 1 GeV^2$ for kinematics in which the produced hadronic state reinteracts predominantly with the spectator nucleon. A comparison of constituent quark model and effective chiral Lagrangian calculations of the $S_{11}$ shows substantial sensitivity to the structure of the produced resonance.

Environmental risk assessment of inorganic chemicals in mining environment.
Creators: name: Pan, Jilang
Publisher: name: Imperial College London

description: Mining is one of the human‟s earliest industrial activities. Indeed early civilizations such as the Bronze Age and Iron Age are named according to their use of metals; the importance of metals is still central to industrialization and urbanization. The enormous quantities of mine waste and tailings generated by mining every year however, are also of concern. The relocation and removal of large quantities of mineral and waste can also release chemicals into the environment especially surface water, groundwater and soil during the mining lifecycle if good mining engineering and mitigation are not performed. To optimise this risk management based on excellent risk analysis is required. The study analysed the mining life cycle, chemicals in the mining environment, current regulations on chemicals in the environment and the development of environmental risk assessment framework with particular focus on the inorganic substances. Chemicals in the mining environment were then grouped into a) the minor constituents of the ore deposits; b) chemicals used in mining such as explosives, leaching chemicals and froth flotation reagents. c) chemicals generated by mining, milling and smelting including Acid mine drainage (AMD) and emissions from smelting and refining. The natural and anthropogenic sources, potential pathways to environmental and human receptors and the implications on human health of key toxic metals and metalloids in the mining context were then evaluated. A new two-tier risk assessment was developed based on the four-step conventional risk assessment framework by the U.S.National Research Council (NRC). Tier 1 involved analysing and evaluating existing data using two new semi-quantitative risk screening and prioritisation procedures, namely Chemicals of Greatest Concern (CGC) and Media of Greatest Concern (MGC). CGC was developed using specific hazardous properties of the inorganic chemicals and their eco-toxicities in the environment. MGC was a system of decomposition using a combination of various decision-making tools such as Multi-criteria decision making (MCDM) and Hierarchical holographic modelling (HHM) to facilitate hazard identification and assessment. Tier 2 involved quantitative toxicity assessment, exposure assessment and risk characterisation which were used to quantify the total risk to human health using Monte Carlo simulations (MCS). The tiered risk-based approach developed was evaluated using three cases studies, viz, the Rustenburg platinum (Pt) mine, South Africa; the Lisheen lead (Pb) – zinc (Zn) mine, Ireland and the Richmond copper (Cu) smelter. The results from them were evaluated and compared as a basis for Anglo American plc‟s global strategic decision making. Finally, the strengths and weakness of the methodology developed were evaluated in relation to the application at current operational level. Future methodology refinement and incorporation of organic chemicals were also discussed.

Subspace Clustering by Block Diagonal Representation

description: This paper studies the subspace clustering problem. Given some data points approximately drawn from a union of subspaces, the goal is to group these data points into their underlying subspaces. Many subspace clustering methods have been proposed and among which sparse subspace clustering and low-rank representation are two representative ones. Despite the different motivations, we observe that many existing methods own the common block diagonal property, which possibly leads to correct clustering, yet with their proofs given case by case. In this work, we consider a general formulation and provide a unified theoretical guarantee of the block diagonal property. The block diagonal property of many existing methods falls into our special case. Second, we observe that many existing methods approximate the block diagonal representation matrix by using different structure priors, e.g., sparsity and low-rankness, which are indirect. We propose the first block diagonal matrix induced regularizer for directly pursuing the block diagonal matrix. With this regularizer, we solve the subspace clustering problem by Block Diagonal Representation (BDR), which uses the block diagonal structure prior. The BDR model is nonconvex and we propose an alternating minimization solver and prove its convergence. Experiments on real datasets demonstrate the effectiveness of BDR.
Factorial correlators: angular scaling within QCD jets

description: Factorial correlators measure the amount of dynamical correlation in multiplicity between two separated phase-space windows. We present the analytical derivation of factorial correlators for a QCD jet described at the double logarithmic (DL) accuracy. We obtain a new angular scaling property for properly normalized correlators between two solid-angle cells or two rings around the jet axis. Normalized QCD factorial correlators scale with the angular distance and are independent of the window size. Scaling violations are expected beyond DL approximation, in particular from the subjet structure. Experimental tests are feasible, and thus welcome.

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: For the closed superstring, spin fields and bi-spinor states are defined directly in four spacetime dimensions. Explicit operator product expansions are given, including those for the internal superconformal field theory, which are consistent with locality and BRST invariance for the string vertices. The most general BRST picture changing for these fields is computed. A covariant notation for the spin decomposition of these states is developed in which non-vanishing polarizations are selected automatically. The kinematics of the three-gluon dual model amplitude in both the Neveu-Schwarz and Ramond sectors in the Lorentz gauges is calculated and contrasted. Modular invariance and enhanced gauge symmetry of four-dimensional models incorporating these states is described.

Isocalar Roper excitation in the pp --> pp pi0 reaction close to threshold
Creators: name: Hernandez, E.
name: Oset, E.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: A new mechanism for the pp --> pp pi0 reaction close to threshold is suggested coming from the isoscalar excitation of the Roper and its decay into N(pi pi)S-wave, with one of the pi0 emitted and the other one reabsorbed on the second nucleon. The mechanism can lead to important interference with other mechanisms and, together with experiment, serves to exclude large ranges of the 2pi N* decay parameters allowed by the N* partial decay widths.
