description: The reaction $p + d \rightarrow p + d + X$ was studied at 0.8-2.0 GeV proton beam energies with the ANKE magnetic spectrometer at the COSY synchrotron storage ring. The proton-deuteron pairs emerging with high momenta, 0.6-1.8 GeV/$c$, were detected at small angles with respect to the proton beam. Distribution over the reaction missing mass $M_x$ reveals a local enhancement near the threshold of the pion pair production specific for the so-called ABC effect. The enhancement has a structure of a narrow bump placed above a smooth continuum. The invariant mass of the $dππ$ system in this enhancement region exhibits a resonance-like peak at $M_{dππ} \approx 2.36$ GeV/$c^2$ with the width $Γ\approx 0.10$ GeV/$c^2$. A possible interpretation of these features is discussed.

Ultrafast measurements using x-ray free-electron lasers
Creators: name: Sanchez Gonzalez, Alvaro
Publisher: name: Imperial College London
Year: 2017

description: X-ray free-electron lasers (XFELs) are unique tools for ultrafast science, allowing one to generate tunable pairs of few-fs x-ray pulses with photon energies between ~10 eV and ~10 keV. XFEL machines are however much larger and much more complex than table-top optical lasers, spanning from several hundreds of metres in length up to a few kilometres. This increased size and complexity makes them very prone to fluctuations and single-shot jitter in the parameters of the generated x-ray pulses such as photon energy, intensity and time delay, of up to ~1%, ~100% and ~15 fs, respectively. Using data from different experiments carried out at the Linac Coherent Light Source (LCLS) and the SPring-8 Angstrom Compact Free Electron Laser (SACLA), the author will show examples of the influence that these fluctuations can have on the experimental signals, proposing solutions to separate this influence from actual meaningful experimental results. The thesis starts with a brief introduction to x-ray science and the working principles of XFELs followed by an extensive description of the common configurations that allow generating pairs of pulses for time-resolved experiments. The first experimental results are then presented for two successful experiments measuring nuclear dynamics in the 10-100 fs timescales in the acetylene and C60 molecules. While successful, these experiments already show the effects of the fluctuations, effects that, as shown in the following chapter, are amplified when attempting to use few-fs pulses to measure few-fs dynamics. Although the presence of the fluctuations may be unavoidable, this thesis shows, using data from three additional ultrafast experiments, that the fluctuations can be circumvented by performing a full single-shot characterization of all x-ray pulses and implementing sophisticated data analysis techniques to sort the experimental data. Finally, having exposed the importance of single-shot x-ray characterization, the author proposes and demonstrates a technique based on machine learning to enable such full x-ray characterization at the next generation of high-repetition-rate XFELs.

description: Verifying quantum states is central to certifying the correct operation of various quantum information processing tasks. In particular, in measurement-based quantum computing, checking whether correct graph states are generated is essential for reliable quantum computing. Several verification protocols for graph states have been proposed, but none of these are particularly resource efficient: multiple copies are required to extract a single state that is guaranteed to be close to the ideal one. The best protocol currently known requires $O(n^{15})$ copies of the state, where $n$ is the size of the graph state. In this paper, we construct a significantly more resource-efficient verification protocol for graph states that only requires $O(n^5\log{n})$ copies. The key idea is to employ Serfling's bound, which is a probability inequality in classical statistics. Utilizing Serfling's bound also enables us to generalize our protocol for qudit and continuous-variable graph states. Constructing a resource-efficient verification protocol for them is non-trivial. For example, the previous verification protocols for qubit graph states that use the quantum de Finetti theorem cannot be generalized to qudit and continuous-variable graph states without tremendously increasing the resource overhead. This is because the overhead caused by the quantum de Finetti theorem depends on the local dimension. On the other hand, in our protocol, the resource overhead is independent of the local dimension, and therefore generalizing to qudit or continuous-variable graph states does not increase the overhead. The flexibility of Serfling's bound also makes our protocol robust: our protocol accepts slightly noisy but still useful graph states.

description: Next-generation touristic services will rely on the advanced mobile networks' high bandwidth and low latency and the Multi-access Edge Computing (MEC) paradigm to provide fully immersive mobile experiences. As an integral part of travel planning systems, recommendation algorithms devise personalized tour itineraries for individual users considering the popularity of a city's Points of Interest (POIs) as well as the tourist preferences and constraints. However, in the context of next-generation touristic services, recommendation algorithms should also consider the applications (e.g., social network, mobile video streaming, mobile augmented reality) the tourist will consume in the POIs and the quality in which the MEC infrastructure will deliver such applications. In this paper, we address the joint problem of recommending personalized tour itineraries for tourists and efficiently allocating MEC resources for advanced touristic applications. We formulate an optimization problem that maximizes the itinerary of individual tourists while optimizing the resource allocation at the network edge. We then propose an exact algorithm that quickly solves the problem optimally, considering instances of realistic size. Using a real-world location-based photo-sharing database, we conduct and present an exploratory analysis to understand preferences and users' visiting patterns. Using this understanding, we propose a methodology to identify user interest in applications. Finally, we evaluate our algorithm using this dataset. Results show that our algorithm outperforms a modified version of a state-of-the-art solution for personalized tour itinerary recommendation, demonstrating gains up to 11% for resource allocation efficiency and 40% for user experience. In addition, our algorithm performs similarly to the modified state-of-the-art solution regarding traditional itinerary recommendation metrics.

description: We investigate the formation of molecular clouds from atomic gas by using three-dimensional magnetohydrodynamic simulations, including non-equilibrium chemical reactions and heating/cooling processes. We consider super-Alfvénic head-on colliding flows of atomic gas possessing the two-phase structure that consists of HI clouds and surrounding warm diffuse gas. We examine how the formation of molecular clouds depends on the angle $θ$ between the upstream flow and the mean magnetic field. We find that there is a critical angle $θ_\mathrm{cr}$ above which the shock-amplified magnetic field controls the post-shock gas dynamics. If the atomic gas is compressed almost along the mean magnetic field ($θ\llθ_\mathrm{cr}$), super-Alfvénic anisotropic turbulence is maintained by the accretion of the highly inhomogeneous upstream atomic gas. As a result, a greatly extended turbulence-dominated post-shock layer is generated. Around $θ\sim θ_\mathrm{cr}$, the shock-amplified magnetic field weakens the post-shock turbulence, leading to a dense post-shock layer. For $θ\gg θ_\mathrm{cr}$, the strong magnetic pressure suppresses the formation of cold dense clouds. Efficient molecular cloud formation is expected if $θ$ is less than a few times $θ_\mathrm{cr}$. Developing an analytic model and performing a parameter survey, we obtain an analytic formula for the critical angle as a function of the mean density, collision speed, and field strength of the upstream atomic gas. The critical angle is found to be less than $\sim 15^\circ$ as long as the field strength is larger than $1~μ$G, indicating that the probability of occurrence of compression with $θ

description: We study the decay rate of the energy of solutions to the damped wave equation in a setup where the geometric control condition is violated. We consider damping coefficients which are $0$ on a strip and vanish like polynomials, $x^β$. We prove that the semigroup cannot be stable at rate faster than $1/t^{(β+2)/(β+3)}$ by producing quasimodes of the associated stationary damped wave equation. We also prove that the semigroup is stable at rate at least as fast as $1/t^{(β+2)/(β+4)}$. These two results establish an explicit relation between the rate of vanishing of the damping and rate of decay of solutions. Our result partially generalizes a decay result of Nonnemacher in which the damping is an indicator function on a strip.

description: We present measurements of the gas-phase C/O abundance ratio in six H II regions in the spiral galaxies M101 and NGC 2403, based on ultraviolet spectroscopy using the Faint Object Spectrograph on the Hubble Space Telescope. The C/O ratios increase systematically with O/H in both galaxies, from log C/O approximately -0.8 at log O/H = -4.0 to log C/O approx. -0.1 at log O/H = -3.4. C/N shows no correlation with O/H. The rate of increase of C/O is somewhat uncertain because of uncertainty as to the appropriate UV reddening law, and uncertainty in the metallicity dependence on grain depletions. However, the trend of increasing C/O with O/H is clear, confirming and extending the trend in C/O indicated previously from observations of irregular galaxies. Our data indicate that the radial gradients in C/H across spiral galaxies are steeper than the gradients in O/H. Comparing the data to chemical evolution models for spiral galaxies shows that models in which the massive star yields do not vary with metallicity predict radial C/O gradients that are much flatter than the observed gradients. The most likely hypothesis at present is that stellar winds in massive stars have an important effect on the yields and thus on the evolution of carbon and oxygen abundances. C/O and N/O abundance ratios in the outer disks of spirals determined to date are very similar to those in dwarf irregular galaxies. This implies that the outer disks of spirals have average stellar population ages much younger than the inner disks.

description: We revisit the uncertainties in the calculation of spin-independent scattering matrix elements for the scattering of WIMP dark matter particles on nuclear matter. In addition to discussing the uncertainties due to limitations in our knowledge of the nucleonic matrix elements of the light quark scalar densities < N |{\bar u} u, {\bar d} d, {\bar s} s| N>, we also discuss the importances of heavy quark scalar densities < N |{\bar c} c, {\bar b} b, {\bar t} t| N >, and comment on uncertainties in quark mass ratios. We analyze estimates of the light-quark densities made over the past decade using lattice calculations and/or phenomenological inputs. We find an uncertainty in the combination < N |{\bar u} u + {\bar d} d | N > that is larger than has been assumed in some phenomenological analyses, and a range of < N |{\bar s} s| N > that is smaller but compatible with earlier estimates. We also analyze the importance of the {\cal O}(α_s^3) calculations of the heavy-quark matrix elements that are now available, which provide an important refinement of the calculation of the spin-independent scattering cross section. We use for illustration a benchmark CMSSM point in the focus-point region that is compatible with the limits from LHC and other searches.

description: We conducted spectroscopic and photometric observations of the optical counterpart of the X-ray transient RX J0117.6-7330 in the Small Magellanic Cloud, during a quiescent state. The primary star is identified as a B0.5 IIIe, with mass M = (18 +/- 2) M(sun) and bolometric magnitude M(bol) = -7.4 +/- 0.2. The main spectral features are strong H-alpha emission, H-beta and H-gamma emission cores with absorption wings, and narrow HeI and OII absorption lines. Equivalent width and FWHM of the main lines are listed. The average systemic velocity over our observing run is v(r) = (184 +/- 4) km/s; measurements over a longer period of time are needed to determine the binary period and the K velocity of the primary. We determine a projected rotational velocity v sin i = (145 +/- 10) km/s for the Be star, and we deduce that the inclination angle of the system is i = (21 +/- 3)deg.

description: We calculate the minimum value of the power in kinetic bulk motion of the galactic superluminal source GRS 1915+105. This value far exceeds the Eddington luminosity for accretion onto a black hole of 10 solar masses. This large value severely limits the possible carriers of the kinetic luminosity at the base of the jet, and favours a jet production and acceleration controlled by a magnetic field whose value, at the base of the jet, exceeds $10^8$ Gauss. The Blandford and Znajek process can be responsible of the extraction of the rotational energy of a Kerr black hole, if lasting long enough to provide the required kinetic energy. This time, of the order of a day, implies that the process must operate in a stationary, not impulsive, mode.

Impact of pressure ﬂuctuations on pipe failures in water distribution networks
Creators: name: Rezaei, Hossein
Publisher: name: Imperial College London
Year: 2016

description: Water utilities operate ageing infrastructures that are degraded by environmental factors and operational stresses. Pipe failures have become a routine, resulting in major interruptions and extensive costs to the society. Pipe failure is a result of complex interactions between a variety of factors contributing to the pipe’s structural degradation and ultimate failure. Previous studies have extensively reviewed environmental and pipe-related factors. However, long term impact of quasi-steady and unsteady pressure variations on metallic pipe failures is not fully investigated. The overall aim of this project is to enhance the understanding of the dynamic pressure variations in water supply networks and evaluate their impact on pipe failures, with motivation to enhance the operational efficiency of water supply infrastructures by managing systems’ hydraulic conditions. In this study, a large-scale survey sampling programme is designed and executed in order to gather network representative high frequency pressure samples. A metric is formulated to quantify the stresses imposed on pipes from pressure variations. Causal analysis is undertaken and relationship between pipe failure and predictor variables are investigated by developing logistic regression models. The study develops a methodology for investigating cost-effectiveness of intervention measures and economic justification of the calm networks. The findings from the study illustrate positive associations between the system’s hydraulic variations and predicted probability of pipe failure. It is shown that deterioration models can be enhanced by including pressure variation characteristics as contributing factors to pipe degradation. Investment in achieving calm networks is demonstrated to be economically justifiable.

description: Image based social networks are among the most popular social networking services in recent years. With tremendous images uploaded everyday, understanding users' preferences on user-generated images and making recommendations have become an urgent need. In fact, many hybrid models have been proposed to fuse various kinds of side information~(e.g., image visual representation, social network) and user-item historical behavior for enhancing recommendation performance. However, due to the unique characteristics of the user generated images in social image platforms, the previous studies failed to capture the complex aspects that influence users' preferences in a unified framework. Moreover, most of these hybrid models relied on predefined weights in combining different kinds of information, which usually resulted in sub-optimal recommendation performance. To this end, in this paper, we develop a hierarchical attention model for social contextual image recommendation. In addition to basic latent user interest modeling in the popular matrix factorization based recommendation, we identify three key aspects (i.e., upload history, social influence, and owner admiration) that affect each user's latent preferences, where each aspect summarizes a contextual factor from the complex relationships between users and images. After that, we design a hierarchical attention network that naturally mirrors the hierarchical relationship (elements in each aspects level, and the aspect level) of users' latent interests with the identified key aspects. Specifically, by taking embeddings from state-of-the-art deep learning models that are tailored for each kind of data, the hierarchical attention network could learn to attend differently to more or less content. Finally, extensive experimental results on real-world datasets clearly show the superiority of our proposed model.

description: We extensively test a recent protocol to demonstrate quantum fault tolerance on three systems: (1) a real-time simulation of five spin qubits coupled to an environment with two-level defects, (2) a real-time simulation of transmon quantum computers, and (3) the 16-qubit processor of the IBM Q Experience. In the simulations, the dynamics of the full system is obtained by numerically solving the time-dependent Schrödinger equation. We find that the fault-tolerant scheme provides a systematic way to improve the results when the errors are dominated by the inherent control and measurement errors present in transmon systems. However, the scheme fails to satisfy the criterion for fault tolerance when decoherence effects are dominant.

description: This paper examines the sensitivity of quantitative assessments of foreign aid on the level of income and its distribution across income groups to alternative modelling and parametric assumptions. It does so with the use of a computable general equilibrium model for Egypt by subjecting the model to alternative assumptions. Although the results are (as expected) sensitive to the assumptions made, they indicate that at least potentially, as for example, when foreign aid takes an appropriate form and is accompanied by appropriate offsetting policies, it can be a useful tool for achieving development at minimum social cost.
Option valuation of smart grid technology projects under endogenous and exogenous uncertainty

description: Electricity demand and renewables penetration are set to increase worldwide over the coming decades as part of the global decarbonisation effort. As a result, distribution networks are expected to face challenges related to increased peaks and undesirable voltage excursions. Hence, significant network reinforcements may be required over the next decades. However, a very significant challenge in realizing this transition is the increased uncertainty that surrounds future distributed generation and load connections in terms of size, location and timing. This uncertainty inadvertently will give rise to the prospect of inefficient investments and stranded assets given that current planning practices remain deterministic. It follows that new planning frameworks are needed that allow the quantification of option value and achieve reduction of stranding risk by encouraging cost-efficient strategic investments through smart technologies under both endogenous and exogenous sources of uncertainty. This thesis presents multi-epoch stochastic optimization models, for the distribution network planning problem, that consider a set of investment options with different techno-economical characteristics so as to reflect the multitude of choices available to planners in a realistic setting characterized by endogenous or exogenous uncertainty. These optimization models are rendered tractable through the use of novel decomposition schemes that effectively help manage the associated increased computational burden. The corresponding simulation results validate that smart technologies constitute valuable options for enabling cost effective integration of distributed generation units and underline the importance of early investment in such assets under decision-dependent uncertainty. In addition, the results emphasize that deterministic approaches systematically undervalue the flexibility that smart assets provide, thereby posing a barrier to the advent of the flexible smart grid paradigm.

Worldwide trends in blood pressure and diabetes

description: High blood pressure and diabetes are leading causes of loss of health and included in the targets set by the World Health Organization to control non-communicable diseases (NCDs) globally. My thesis aims to provide comparable estimates of levels and trends in blood pressure and diabetes worldwide. Data were collated via the NCD Risk Factor Collaboration (NCD-RisC) network, from population-based studies that had measured blood pressure from 1975 to 2015, or had measured one or more biomarkers of diabetes from 1980 to 2014. A total of 1,479 studies with 19.1 million participants aged 18 years or older were used in the blood pressure analysis, and 751 studies with 4.4 million participants in the diabetes analysis. I used a Bayesian hierarchical model to estimate trends for 200 countries in the world. Overall, there have been divergent trends in blood pressure, seeing a shift of high blood pressure levels from high-income countries to low- and middle-income countries. The global number of adults affected with raised blood pressure has almost doubled since 1975, driven by population growth and ageing, reaching 1.13 billion in 2015. Similarly, age-standardised diabetes prevalence has increased in almost every country, except those in north-western Europe where the trends have been largely flat. The number of adults affected with diabetes has nearly quadrupled, totalling 422 million in 2014. If post-2000 trends continue, for the world as a whole, the probabilities of meeting the global targets of 25% reduction in raised blood pressure and no rise in diabetes compared to their 2010 levels are 0% for blood pressure and ≤1% for diabetes. A preliminary analysis showed diminishing associations of blood pressure and diabetes with national macroeconomic indicators over time, and weak associations with some measures of food and nutrition.
Current deflection NDE for pipe inspection and monitoring

description: The detection of corrosion on insulated and/or coated pipes in the oil and gas industry remains a challenge. Routine inspection, which is commonly achieved with in-line tools known as "pigs", is not possible where there is any risk of the pig becoming stuck. There are thousands of kilometers of pipe worldwide deemed ``unpiggable'' whose safety must be ensured using Non-Destructive Evaluation (NDE) external to the pipe if potentially catastrophic failure is to be avoided. Many NDE techniques lack sufficient sensitivity due to the coating thickness producing a high standoff distance between the pipe and the sensor and therefore require costly and time-consuming removal of the coating. A method capable of detecting and/or monitoring of defects (e.g. one-third-wall depth corrosion) while leaving the insulation/coating intact would be highly attractive. This thesis documents the development of a technique in which a low-frequency AC current is directly injected into the pipe at distant locations, and perturbations in the magnetic field caused by "current deflection" around defects are measured using solid-state magnetic sensors. Two methods of applying this novel technique were investigated. Firstly, scanning the sensors to measure perturbations in the field and screen for defects, and secondly, permanently installing sensors outside the pipe for Structural Health Monitoring (SHM). A Finite Element (FE) model has been developed and used to investigate the practical challenges that are faced by the technique and how these may be overcome. The sensitivity of the technique for defect detection by external pipe scanning in a practical scenario has then been evaluated using a model-assisted Probability of Detection (POD) framework that combines the measurements of the signal from an undamaged pipe with synthetic damage profiles and contributions from general corrosion and sensor misalignment. The results indicate that good performance is expected for damage detection by scanning above a typical insulation thickness with just a few amps of injected current. A similar framework has then been used to evaluate the sensitivity of the technique as an SHM solution which suggests excellent corrosion detection performance with the permanent installation of inexpensive magnetic sensors. The technique has potential advantages over competing methods in both scanning and monitoring modes and there are many opportunities for future development.

description: Static synthetic magnetic fields give rise to phenomena including the Lorentz force and the quantum Hall effect even for neutral particles, and they have by now been implemented in a variety of physical systems. Moving towards fully dynamical synthetic gauge fields allows, in addition, for backaction of the particles' motion onto the field. If this results in a time-dependent vector potential, conventional electromagnetism predicts the generation of an electric field. Here, we show how synthetic electric fields for photons arise self-consistently due to the nonlinear dynamics in a driven system. Our analysis is based on optomechanical arrays, where dynamical gauge fields arise naturally from phonon-assisted photon tunneling. We study open, one-dimensional arrays, where synthetic magnetic fields are absent. However, we show that synthetic electric fields can be generated dynamically, which, importantly, suppress photon transport in the array. The generation of these fields depends on the direction of photon propagation, leading to a novel mechanism for a photon diode, inducing nonlinear nonreciprocal transport via dynamical synthetic gauge fields.

Novel spectroscopy techniques for functional imaging of bacterial biofilms at microscopic level

description: Biofilms are complex aggregations of microorganisms in which cells adhere on a surface and are held together in a matrix of extracellular polysaccharide substances (EPS). Biofilms are very resistant to attacks and are responsible for the majority of bacterial infections. They are highly heterogeneous and within colonies, both chemical and physical gradients exist. Therefore, in order to study and understand their functionalities, it is essential to develop methods that can provide information at high spatiotemporal resolutions. In this thesis, two novel spectroscopic techniques, namely Transient State (TRAST) monitoring and Brillouin Imaging – that can optically measure oxygen distributions and stiffness of the sample, respectively – are presented and employed for the study of Pseudomonas aeruginosa biofilms. Using TRAST, we found anoxic zones within the colonies. We also observed that oxygen consumption extends outside the areas of high cell densities, establishing a gradient between the biofilm interior and air saturation at the exterior. Using Brillouin microscopy, we found two distinct stiffness patterns in colonies: in younger colonies stiffness increased towards their interior, whereas, some larger (> 45 μm in diameter) colonies were found to have less stiff interiors, suggesting they were hollow, or possibly undergoing transition to the seeding dispersal stage. The tools presented here can offer information in high spatial resolutions that can be applied to address emerging questions about the biofilm mode of life.
The role of EspO1 in Escherichia coli pathogenesis

Publisher: name: Imperial College London

description: Enterohaemorrhagic E. coli (EHEC) has been the causative agent of diarrhoeal outbreaks for decades. EHEC virulence relies on a type 3 secretion system (T3SS), which directly translocates T3SS effectors into the host cell cytoplasm. Once translocated, T3SS effectors alter various host cell functions, including manipulating the cell death response, in order to facilitate bacterial colonisation. EHEC is equipped with at least 40 effector proteins; however, not all identified effectors are fully characterised. This study set out to investigate the role of EspO during EHEC infection. EHEC O157:H7 strain EDL933 carries 2 EspO homologs: EspO1 and EspO2. EspO homologs are also found in several enteric pathogens including Shigella flexneri (OspE1 and OspE2), Salmonella enterica serovar Typhi and Typhimurium (SopD), Citrobacter rodentium (EspO), and some enteropathogenic E. coli (EPEC) clinical isolates (EspO). It has previously been established that the EspO effector family interacts with integrin linked kinase (ILK) via a conserved tryptophan residue: W68 for OspE1 and W77 for EspO1. EspO1 and EspO2 co-operatively inhibit cell detachment by blocking focal adhesion disassembly, via their interactions with ILK and EspM2, respectively. In a previous study, HAX-1 was identified as the novel interaction partner of EspO1 by a yeast 2 hybrid (Y2H) screen. HAX-1 is an ubiquitiously expressed anti-apoptotic protein that localises to mitochondria. In this study, the EspO1-HAX-1 interaction was confirmed by direct Y2H. Functionally, EspO1 and OspE1 were shown to protect HeLa cells from staurosporine-induced apoptosis during transfection and EspO1 was able to inhibit cell death during in vitro infection. Additionally it was established that the EspO1 and OspE1 anti-apoptotic activity is HAX-1 dependent, but ILK independent. To summarise, this study reported that EspO1 displays anti-apoptotic activity in a HAX-1 dependent manner. Therefore, EspO1 serves 2 main functions: inhibition of apoptosis through HAX-1 and blocking of cell detachment through ILK.
