description: We propose a Las Vegas probabilistic algorithm to compute the zeta function of a genus-3 hyperelliptic curve defined over a finite field $\mathbb F_q$, with explicit real multiplication by an order $\mathbb Z[η]$ in a totally real cubic field. Our main result states that this algorithm requires an expected number of $\widetilde O((\log q)^6)$ bit-operations, where the constant in the $\widetilde O()$ depends on the ring $\mathbb Z[η]$ and on the degrees of polynomials representing the endomorphism $η$. As a proof-of-concept, we compute the zeta function of a curve defined over a 64-bit prime field, with explicit real multiplication by $\mathbb Z[2\cos(2π/7)]$.

description: We present a study of recent solar neutrino data using a Bayesian method. Assuming that only $ν_e$ are observed in the Super-Kamiokande experiment our results show a marked supression of the survival probability at about 1 MeV, in good agreement with $χ^2$-based analyses. When the detection of $ν_μ$ by Super-Kamiokande is taken into account, assuming $ν_e$ to $ν_μ$ oscillations, we find the largest suppression in survival probability at about 8.5 MeV.

The role of specific amino acids in the regulation of food intake
Creators: name: Greenwood, Hannah Catherine
Publisher: name: Imperial College London
Year: 2011

description: It is well established that ingested protein has a greater satiating effect than other macronutrients. The mechanisms behind this effect are unknown, although it is believed that protein induces a greater increase in levels of anorectic gut hormones than carbohydrate or fat. Recent identification of a family of promiscuous L-amino acid receptors has provided a potential mechanism for the effects of protein on appetite. These amino acid receptors - the G-protein coupled receptor family C group 6 member A (GPRC6A), the Taste receptor type 1 member 1/Taste receptor type 1 member 3 (T1R1/T1R3) dimer and the calcium-sensing receptor (CaR) - are non-specific in their ligand binding but show preference for different families of amino acids. I assessed the effects of peripheral administration of a wide range of amino acids on food intake in rodents. My results demonstrate that the specific amino acids L-arginine, L-cysteine and L-lysine acutely reduce food intake following peripheral administration. The 0-1 hour food intake following both intraperitoneal (i.p.) and oral administration of amino acids in rats negatively correlated with the stimulatory efficacy of amino acids at the T1R1/T1R3. I subsequently investigated the mechanisms by which L-arginine, L-cysteine and L-lysine inhibit food intake. Oral administration, of L-arginine and L-lysine tended to increase levels of the anorectic hormones glucagon-like peptide 1 (GLP-1) and peptide YY (PYY). Intraperitoneal administration of L-cysteine reduced levels of circulating total and acyl-ghrelin. Conditioned taste aversion studies suggested that the anorectic effect of these amino acids is not secondary to visceral illness. Chronic administration of L-cysteine significantly reduces cumulative food intake. My studies suggest that specific amino acids can influence food intake, perhaps by altering circulating levels of gastrointestinal hormones. Altering dietary amino acid content may be helpful to prevent or treat obesity.
The ASCA X-Ray Spectrum Of The Broad-Line Radio Galaxy Pictor A: A Simple Power Law With No Fe K-alpha Line

description: We present the X-ray spectrum of the broad-line radio galaxy Pictor A as observed by ASCA in 1996. The main objective of the observation was to detect and study the profiles of the Fe~K$α$ lines. The motivation was the fact that the Balmer lines of this object show well-separated displaced peaks, suggesting an origin in an accretion disk. The 0.5-10 keV X-ray spectrum is described very well by a model consisting of a power law of photon index 1.77 modified by interstellar photoelectric absorption. We find evidence for neither a soft nor a hard (Compton reflection) excess. More importantly, we do not detect an Fe K-alpha line, in marked contrast with the spectra of typical Seyfert galaxies and other broad-line radio galaxies observed by ASCA. The 99%-confidence upper limit on the equivalent width of an unresolved line at a rest energy of 6.4 keV is 100 eV, while for a broad line (FWHM of approximately 60,000 km/s) the corresponding upper limit is 135 eV. We discuss several possible explanations for the weakness of the Fe K-alpha line in Pictor~A paying attention to the currently available data on the properties of Fe K-alpha lines in other broad-line radio galaxies observed by ASCA. We speculate that the absence of a hard excess (Compton reflection) or an Fe K-alpha line is an indication of an accretion disk structure that is different from that of typical Seyfert galaxies, e.g., the inner disk may be an ion torus.

The regionality of cardiac beta-2-adrenoceptor signalling
Creators: name: Wright, Peter
Publisher: name: Imperial College London
Year: 2013

description: The dysfunction of the apical myocardium is observed following chronic exposure to catecholamines, or after acutely stressful scenarios, in the syndrome of Takotsubo cardiomyopathy. The physiological functions of the β2AR were assessed via measurement of cell shortening; β2AR-cAMP signalling was assessed by FRET microscopy, comparing cells from the apical and basal myocardium. The effects of pre-stimulation of the β2AR with high levels of endogenous catecholamines were investigated to simulate pathological scenarios. The structure of the cellular membranes of cells from different myocardial regions was assessed and manipulated to investigate their role in β2AR signalling. An improved animal model of the regional pathology in Takotsubo was investigated using ovariectomized female rats. Apical cardiomyocytes are sensitized to β2AR stimulation, displaying larger increases in inotropy and lusitropy in comparison to basal cells. This was not due to differences in cAMP levels induced by β2AR within the cell cytosol. Differences were apparent in the amount of cAMP reaching the RII-PKA domains (the main arbiters of cellular inotropy and lusitropy). β2AR-cAMP signalling was discovered to be more persistent in the apical cardiomyocytes. Basal cardiomyocytes were found to have a larger number of caveolae within their membranes, caveolae have been demonstrated to modulate β2AR. Following the disruption of caveolar domains via chelation of cholesterol, apical and basal responses to β2AR stimulation were equalized; inhibition of phosphodiesterase 4 had the same effect. Catecholamine pre-stimulation reduced β2AR responses; adrenaline pre-stimulation exerts a more Gi-dependent desensitization than noradrenaline. Female rats are shown to be relatively protected from the effects of adrenergic overstimulation and ovariectomized female rats suffer acutely high mortality. Cells from different regions of the myocardium may control their receptor signalling in different ways to produce desirable physiological activity. In settings of pathology this phenomena may leave certain regions vulnerable to damage.

description: The circumstellar disk of the Herbig Fe star HD 142527 is host to several remarkable features including a warped inner disk, a 120 au-wide annular gap, a prominent dust trap and several spiral arms. A low-mass companion, HD 142527 B, was also found orbiting the primary star at $\sim$14 au. This study aims to better characterize this companion, which could help explain its impact on the peculiar geometry of the disk. We observed the source with VLT/SINFONI in $H$+$K$ band in pupil-tracking mode. Data were post-processed with several algorithms based on angular differential imaging (ADI). HD 142527 B is conspicuously re-detected in most spectral channels, which enables us to extract the first medium-resolution spectrum of a low-mass companion within 0.1'' from its central star. Fitting our spectrum with both template and synthetic spectra suggests that the companion is a young M2.5$\pm$1.0 star with an effective temperature of $3500\pm100$ K, possibly surrounded with a hot (1700 K) circum-secondary environment. Pre-main sequence evolutionary tracks provide a mass estimate of $0.34\pm0.06 M_{\odot}$, independent of the presence of a hot environment. However, the estimated stellar radius and age do depend on that assumption; we find a radius of $1.37 \pm 0.05 R_{\odot}$ (resp. $1.96 \pm 0.10 R_{\odot}$) and an age of $1.8^{+1.2}_{-0.5}$ Myr (resp. $0.75 \pm 0.25$ Myr) in the case of the presence (resp. absence) of a hot environment contributing in $H$+$K$. Our new values for the mass and radius yield a mass accretion rate of $\sim$5 $\times 10^{-9} M_{\odot}$ yr$^{-1}$ (2-3% that of the primary). Our results illustrate thus the potential for SINFONI+ADI to characterize faint close-in companions. The new spectral type makes HD 142527 B a twin of the well known TW Hya T-Tauri star, and the revision of its mass to higher values further supports its role in shaping the disk.

description: A variety of machine learning models have been proposed to assess the performance of players in professional sports. However, they have only a limited ability to model how player performance depends on the game context. This paper proposes a new approach to capturing game context: we apply Deep Reinforcement Learning (DRL) to learn an action-value Q function from 3M play-by-play events in the National Hockey League (NHL). The neural network representation integrates both continuous context signals and game history, using a possession-based LSTM. The learned Q-function is used to value players' actions under different game contexts. To assess a player's overall performance, we introduce a novel Game Impact Metric (GIM) that aggregates the values of the player's actions. Empirical Evaluation shows GIM is consistent throughout a play season, and correlates highly with standard success measures and future salary.

description: Human activity recognition is typically addressed by detecting key concepts like global and local motion, features related to object classes present in the scene, as well as features related to the global context. The next open challenges in activity recognition require a level of understanding that pushes beyond this and call for models with capabilities for fine distinction and detailed comprehension of interactions between actors and objects in a scene. We propose a model capable of learning to reason about semantically meaningful spatiotemporal interactions in videos. The key to our approach is a choice of performing this reasoning at the object level through the integration of state of the art object detection networks. This allows the model to learn detailed spatial interactions that exist at a semantic, object-interaction relevant level. We evaluate our method on three standard datasets (Twenty-BN Something-Something, VLOG and EPIC Kitchens) and achieve state of the art results on all of them. Finally, we show visualizations of the interactions learned by the model, which illustrate object classes and their interactions corresponding to different activity classes.

Modelling land-use and climate change impacts on hydrology: the Upper Ganges river basin
Creators: name: Tsarouchi, Georgia-Marina
Publisher: name: Imperial College London
Year: 2014

description: This thesis explores the effects that large-scale land-use/cover change (LUCC) and climate change pose to the terrestrial water cycle, by developing a case study in the Upper Ganges (UG) river basin, in India. In an area experiencing rapid rates of LUCC and changes in irrigation practices, historic land-use maps are developed, based on satellite images, to investigate historical trends of LUCC. Future projection scenarios of LUCC for years up to 2035 are derived from Markov chain analysis. To explore the impacts of those changes in hydrology, the generated maps are used to force the Land Surface Model (LSM) JULES. JULES is found to be reasonably skilful in terms of its ability to reproduce observed streamflow. However, the results indicate that there is much room left for improved estimates of evapotranspiration (ET) fluxes, which JULES is found to over-predict. By dynamically coupling JULES with the crop model InfoCrop, the simulated ET fluxes are improved, compared to the original JULES model. The difference in mean annual ET between the two models (coupled and original) is approximately 150 mm/yr and indicates the potential error in ET flux estimations of an LSM without dynamic vegetation. The impact of LUCC and climate change on the hydrological response of the UG basin is quantified, by calculating variations in hydrological components (streamflow, ET and soil moisture) during the period 2000–2035. Severe increases in the high extremes of flows (+40% in the multi-model mean) are being projected for the nearby future (2030–2035). The changes in all examined hydrological components are greater in the combined land-use and climate change scenario, whilst climate change is the main driver of those changes. These results provide the necessary evidence-base to support regional land-use planning, advanced irrigation practices and develop future-proof water resource management strategies under a water-limited environment.

description: We study statistical anisotropies generated in the observed two-point function of the cosmic microwave background (CMB) fluctuations if the primordial statistics are non-Gaussian. Focusing on the dipole modulations of the anisotropies, we find that the hemispherical power asymmetry observed in the CMB temperature fluctuations can be modeled by a local-type trispectrum with amplitude $τ_{\rm NL}(k_p=0.05~{\rm Mpc}^{-1}) \approx 2 \times 10^4$ and a large red tilt $n\approx -0.68$. We numerically evaluate the non-Gaussian covariance of the modulation estimators for both temperature and E-mode polarization fluctuations and discuss the prospects of constraining the model using Planck satellite data. We then discuss other effects of the scale-dependent trispectrum that could be used to distinguish this scenario from other explanations of the power asymmetry: higher-order modulations of the two-point function and the non-Gaussian angular power spectrum covariance. As an important consequence of the non-Gaussian power spectrum covariance, we discuss how the CMB-inferred spectral index of primordial scalar fluctuations can be significantly biased in the presence of a scale-dependent local-type trispectrum.

description: We study a spherically symmetric setup consisting of a Schwarzschild metric as the background geometry in the framework of classical polymerization. This process is an extension of the polymeric representation of quantum mechanics in such a way that a transformation maps classical variables to their polymeric counterpart. We show that the usual Schwarzschild metric can be extracted from a Hamiltonian function which in turn, gets modifications due to the classical polymerization. Then, the polymer corrected Schwarzschild metric may be obtained by solving the polymer-Hamiltonian equations of motion. It is shown that while the conventional Schwarzschild space-time is a vacuum solution of the Einstein equations, its polymer-corrected version corresponds to an energy-momentum tensor that exhibits the features of dark energy. We also use the resulting metric to investigate some thermodynamical quantities associated to the Schwarzschild black hole, and in comparison with the standard Schwarzschild metric the similarities and differences are discussed.

description: We study transport properties and topological phase transition in two-dimensional interacting disordered systems. Within dynamical mean-field theory, we derive the Hall conductance, which is quantized and serves as a topological invariant for insulators, even when the energy gap is closed by localized states. In the spinful Harper-Hofstadter-Hatsugai model, in the trivial insulator regime, we find that the repulsive on-site interaction can assist weak disorder to induce the integer quantum Hall effect, while in the topologically non-trivial regime, it impedes Anderson localization. Generally, the interaction broadens the regime of the topological phase in the disordered system.

description: Tensor force is identified in each meson-nucleon coupling in the relativistic Hartree-Fock theory. It is found that all the meson-nucleon couplings, except the $σ$-scalar one, give rise to the tensor force. The effects of tensor force on various nuclear properties can now be investigated quantitatively, which allows fair and direct comparisons with the corresponding results in the non-relativistic framework. The tensor effects on nuclear binding energies and the evolutions of the $Z,\,N = 8,\,20$, and $28$ magic gaps are studied. The tensor contributions to the binding energies are shown to be tiny in general. The $Z,\,N = 8$ and $20$ gaps are sensitive to the tensor force, but the $Z,\,N = 28$ gaps are not.

description: Spinacia oleracea L. (Spinach) is a leafy vegetable which is considered to have a high nutritional value. Flavonoids in spinach were reported to act as antimutagenic property. Rapid detection of these flavonoids in Spinach was achieved by using HPLC-ESI-QTOF-MS/MS. Thirty six compounds were tentatively identified based on their retention times, accurate mass and MS/MS spectra. The fragmentation patterns of known compounds were applied to elucidate the structure of their corresponding derivatives having the same basic skeleton. Out of thirty six peaks, three peaks were assigned as patuletin and six peaks were assigned as spinacetin derivatives. Twelve compounds were first time identified following the fragmentation pattern of known compounds. Five of the identified compounds i.e., spinacetin, 5,3′,4′-trihydroxy-3-methoxy-6,7-methylenedioxyflavone, protocatechuic acid, ferulic acid and coumaric acid were simultaneously quantified in spinach leaves by a validated UPLC-ESI-MS/MS method under MRM mode.

These can then be used to faithfully teleport unknown quantum states from one observer to the other, thereby achieving faithful transfrom one observer to the other, thereby achieving faithful transmission of quantum information through a noisy channel. We give upper and lower bounds on the yield $D(M)$ of pure singlets ($\ket{Ψ^-}$) distillable from mixed states $M$, showing $D(M)>0$ if $\bra{Ψ^-}M\ket{Ψ^-}>\half$.

description: The collapse of a vapor bubble near a flat solid boundary results in the formation of a jet that is directed towards the boundary. In more complex geometries such as corners, predictions of the collapse cannot be made in a straightforward manner due to the loss of axial symmetry. We experimentally investigate the bubble collapse and jet formation in corners formed of two flat solid boundaries with different opening angles. Using potential flow analysis, we accurately predict the direction of the jet and bubble displacement. We further show that for a corner with an opening angle $α$, there exist analytic solutions that predict the jet direction for all the cases $α=π/n$, where $n$ is a natural number. These solutions cover, in discrete steps, the full range of corners from the limiting case of a bubble near a single wall ($n=1$) up to a bubble in between parallel walls ($n\rightarrow\infty$).

Modelling electric vehicle use and charging behaviour
Creators: name: Daina, Nicolo
Publisher: name: Imperial College London
Year: 2014

description: This thesis explores the role of consumers’ choices into the integration of mobility and power systems. It will contribute to the wider literature of electric vehicles-power systems integration by explicitly accounting for consumers’ preferences in shaping charging demand. This objective is achieved by developing a methodology to investigate electric vehicles (EV) charging choices in technological scenarios that enable smart charging operations. A modelling framework for the joint analysis of EV charging and activity-travel behaviour is introduced. This is based on an extension of traditional activity scheduling models that embeds the charging choice dimensions: namely the available energy after charging (that is related to the driving range) and the charging duration (defined here as the time elapsed from arrival at a charging facility until the desired battery level is achieved). This framework accommodates the interaction between charging behaviour and travel/activity behaviour, and allows us to capture the potential effects of charging service pricing and charging demand management policies on charging choices as well as along the timing dimension of travel/activity choices. A stated response survey instrument for estimating a tour-based operational version of the model is developed. Results from this empirical study provide insights into the value placed by individuals on the main attributes of the charging choice. The trade-offs between target battery levels and schedule delays potentially induced by long durations of the charging operation are also analysed. The model is then implemented into a micro-simulation framework to demonstrate the model applicability for modelling electric vehicle charging demand. The specific application shows the compatibility of charging choices under various electricity pricing scenarios with electric vehicle load flexibility – an essential requirement to enable smart charging operations.
Molecular characteristics of the CupB chaperone-usher pathway and the Tps4 two-partner secretion system in Pseudomonas aeruginosa
Creators: name: Muhl, Daniela
Publisher: name: Imperial College London

description: The opportunistic human pathogen Pseudomonas aeruginosa is a threat for immunocompromised individuals, a major cause of nosocomial infections, and is prevalent in patients with cystic fibrosis. The bacterium can form biofilms that help it evade the immune response. It adheres to host cells using molecular adhesins, such as pili assembled by chaperone-usher pathways (Cup). Understanding the adhesion could, therefore, help develop treatments that prevent the establishment of infections. This thesis considers the CupB system, consisting of an usher (CupB3), two chaperones (CupB2 and CupB4) and two pilin subunits (CupB1 and CupB6). The chaperones target the pilin subunits to the usher assembling a CupB1-containing pilus with a putative CupB6 adhesin at its tip. The cupB operon also encodes the TpsA-like protein (two partner secretion) CupB5, previously suggested to be secreted by CupB3. The aim of this work was to understand the CupB1-containing pilus assembly and CupB5 secretion mechanism. Genetic and biochemical techniques were used, such as deletion or point mutation, qRT-PCR, pull-down assays, shearing assays, and protein structure prediction or resolution. They led to the following results. First, each chaperone likely has a cognate substrate: CupB1 interacts with CupB2 and CupB6 with CupB4. Second, the crystal structure solved for CupB6 showed that it has a pilin and a putative adhesin domain, connected by a poly-proline linker. Third, CupB5 secretion was observed to be CupB3-independent and TpsB4-dependent. tpsB4 is encoded with its substrate tpsA4. The expression of the cupB and tpsB4/tpsA4 operons was shown to be controlled by the same regulatory pathway, Roc1, and deletion of the tpsB4 transporter gene abolished CupB5 secretion. Fourth, a structural analysis indicated that TpsB4 has two POTRA domains, and POTRA-1 interacts with the highly homologue TPS motifs of CupB5 and TpsA4. Based on these results, the thesis presents a model of CupB pilus assembly and CupB5 secretion.

Numerical investigation of tunnelling beneath existing tunnels

description: Tunnels under large metropolitan cities have been constructed for almost two centuries. As the cities expand their surface and subsurface space become congested. The construction of the new Crossrail tunnels under central London, which has been on-going during the preparation of this thesis, has more than 30 interfaces with existing London underground tunnels. In this thesis the effects of excavating the Crossrail tunnels under the existing Central line tunnels below Bayswater road are explored and various aspects of tunnelling in London clay are investigated using the finite element code ICFEP (Imperial College Finite Element Program). The first part of this thesis focuses on the short and long-term behaviour of grey cast iron tunnel linings by modelling the cross-section of the Central line tunnels under Bayswater Road. The effect of the lining permeability on the lining response in terms of deformation and internal forces is highlighted. Simulations of a large-scale experimental set-up (that studies the lining behaviour) are made and ways to overcome some of the experimental limitations are presented. In the second part of the thesis the use of a sophisticated two surface kinematic hardening model for modelling tunnelling in stiff London clay is explored by analysing the Jubilee Line Extension under St. James’s Park and the Crossrail tunnels under Hyde Park. The calibration of the model parameters against laboratory tests on intact samples and the modelling of previous stress history improve the predicted soil displacements due to tunnelling. In the last part of this thesis, a three-dimensional numerical model is used in order to qualitatively estimate the response of the Central line tunnels due to the excavation of the new Crossrail tunnels. Despite the simplifications made, the numerical predictions show that finite element analysis is a useful and reliable tool to analyse such complicated problems.
Hazard identification and risk analysis of nighttime offshore helicopter operations

Publisher: name: Imperial College London

description: Helicopters play a vital role in the movement of people and cargo to and from the installations of the oil and gas industry at sea, often in challenging environments, such as nighttime, where accidents tend to have serious impacts. The ability to remain safe is largely reliant on the processes of hazard identification and risk analysis. However, the processes currently used do not provide the offshore helicopter industry with the desired levels of safety in nighttime operations. The reasons for this include serious methodological weaknesses in current processes, especially the lack of a holistic view of the safety-critical components of the industry; biased and over-simplistic analysis of accidents; overreliance on reported incidents of doubtful statistical utility; ad hoc survey methods to elicit opinions of pilots rather than facts about hazards; and the complete absence of predictive analysis using hazard data. This thesis addresses these weaknesses by developing and implementing a new and comprehensive methodology consisting of a number of processes used in an integrated manner, with novel contributions in taxonomy development, data quality and qualitative and quantitative data analytics to enhance hazard identification and risk analysis of nighttime offshore helicopter operations. The thesis demonstrates that this new methodology is effective in describing the safety-critical components of the offshore helicopter industry, identifying systematic hazards patterns and trends from the statistical analysis of accident reports, establishing the appropriate use of incident reports for hazard identification and risk analysis and exploiting knowledge and facts elicited directly from surveys of pilots to discriminate accurately the riskiest phases of flight, identify an exhaustive and statistically representative range of hazards related to the riskiest of such phases and analyse the hazard data through quantitative predictive analysis. The methodology is easily transferable to other operations in the helicopter domain by institutions of international reach (e.g., the International Civil Aviation Organisation, ICAO) and individual helicopter operators.

description: Conformal supergravity amplitudes are obtained from the double-copy construction using gauge-theory amplitudes, and compared to direct calculations starting from conformal supergravity Lagrangians. We consider several different theories: minimal ${\cal N}=4$ conformal supergravity, non-minimal ${\cal N}=4$ Berkovits-Witten conformal supergravity, mass-deformed versions of these theories, as well as supersymmetry truncations thereof. Coupling the theories to a Yang-Mills sector is also considered. For all cases we give the gravity Lagrangians that the double copy implicitly generates. The two main results are: we determine a Lagrangian for the non-minimal Berkovits-Witten theory, and we uncover the double-copy prescription for the minimal ${\cal N}=4$ conformal supergravity.

description: A fast and simple screening fluorescent method was developed and applied for detection of quinolones in groundwater samples. The experimental conditions for quinolone family detection in 96-well plates were acid media (pH = 4.85) from acetate buffer solution (0.1 mol L−1) and 5.8 × 10−3 mol L−1 of anionic surfactant sodium dodecyl sulfate (SDS) as micellar media at excitation and emission wavelengths of 280 and 450 nm, respectively. The developed method was validated to guarantee the quality of the results reported. Thus, the decision limit (CCα) of ciprofloxacin of 6.8 μg L−1, the most prescript quinolone in our country, was selected as the cut-off level to classify the water samples as ‘suspect’ or ‘negative’ referred to quinolone content. The method showed good recoveries ranging between 80 and 114% for 6.8 μg L−1 ciprofloxacin with relative standard deviation values lower than 13%. Moreover, other families of antibiotics such as aminoglycoside, penicillin, macrolide, sulfonamide and tetracycline did not present interference in the quinolone detection. Groundwater samples from Argentine regions with intensive livestock activities were analysed by this method, and the results had a good correlation with a reference method based on ultraperformance liquid chromatography coupled to mass spectrometry.
