description: We analyse the spatially resolved colours of distant galaxies of known redshift in the Hubble Deep Field, using a new technique based on matching resolved four-band internal colour data to the predictions of evolutionary synthesis models. We quantify the relative age, dispersion in age, ongoing star-formation rate, star-formation history, and dust content of these galaxies. To demonstrate the potential of the method, we study the near-complete sample of 32 I<21.9 mag galaxies with ~ 0.5 studied by Bouwens et al (1997).

description: We consider processes where an electroweak gauge boson ($W$ and $Z$) is produced in the decays of a heavy fermion. The polarization state of the produced gauge boson is given in terms of a vector polarization and a rank-2 tensor polarization. In the rest frame of the mother fermion, these are given directly by the dynamical parameters of the underlying theory. In a frame where the mother particle is moving, the polarization parameters of the gauge boson are dependent additionally upon kinematical factors. We show that these kinematical factors depend only on the magnitude of the velocity of the mother particle and derive analytical expressions for them. We apply the results to pair production of heavy fermions at the LHC with one of the fermions decaying to a gauge boson ($W$, $Z$) and a light Standard Model fermion. We construct estimators of laboratory frame values of polarization parameters of the produced gauge boson. These estimators can be used to estimate the laboratory frame values of polarization parameters of the produced gauge boson without a detailed simulation of the entire process. We validate our expressions with detailed Monte Carlo simulations in the context of beyond the Standard Model scenarios which have a vector-like top partner. We also indicate how to include finite width effects of the heavy fermion in some special cases.

description: We have begun a program to discover high-redshift supernovae ($z \approx$ 0.25--0.5), and study them with follow-up photometry and spectroscopy. We report here our first discovery, a supernova at $z = 0.458$. The photometry for this supernova closely matches the lightcurve calculated for this redshift from the template of well-observed nearby Type Ia supernovae. We discuss the measurement of the deceleration parameter $q_0$ using such high-redshift supernovae, and give the best fit value assuming this one supernova is a normal, unextincted Type Ia. We describe the main sources of error in such a measurement of $q_0$, and ways to reduce these errors.

A contribution in: hedging and portfolio optimisation under weak stochastic target constraints
Creators: name: Bouveret, Géraldine
Publisher: name: Imperial College London
Year: 2016

description: This thesis aims at investigating hedging and portfolio optimisation problems under weak stochastic target constraints. Our first contribution consists in the representation of the hedging price of some contingent claims under both probabilistic and expected shortfall ("weak") constraints holding on a set of dates. We consider a Markovian and complete market framework and favour a dual approach. This work is an extension to Föllmer and Leukert (1999,2000). We then extend the previous results to the case where the wealth process diffusion is semi-linear in the control/strategy variable. The previous convex duality machinery does not apply anymore and we rely on PDE arguments. Bouchard, Elie and Touzi (2009) already proved the PDE characterisation of such price functions but a comparison result, necessary to build a convergent numerical scheme, is still missing in the literature. We will prove that such a result actually holds. The main difficulty arises from the discontinuity of the operators involved in the PDE characterisation of the price function. An application to the quantile hedging of Bermudan options is provided. Our third contribution relies on the PDE characterisation of the problem of portfolio optimisation under a European quantile hedging constraint. We extend the results of Bouchard, Elie and Imbert (2010) to the case where the constraint holds in a weaker sense. The study is based on a reformulation of the initial constraint into an obstacle and almost-sure stochastic target one. This reduction is done by the introduction of an additional controlled state variable coming from the diffusion of the probability of reaching the target (see Bouchard, Elie and Touzi (2009)) and by means of the Geometric Dynamic Programming principle of Soner and Touzi (2002). However this additional controlled state variable raises non-trivial boundary conditions that have to be characterised. We also have to handle the discontinuity of the operators involved in the characterisation.

A Generalized $K$ correction for Type Ia Supernovae: Comparing R-band Photometry Beyond z=0.2 with B, V, and R-band Nearby Photometry

description: Photometric measurements show that as a group nearby type Ia supernovae follow similar lightcurves and reach similar peak magnitudes Thus, these supernovae can serve as standard candles or calibrated candles at cosmological distances. Magnitudes of local and distant supernovae, both in the same filter band, are compared using a $K$ correction to account for the different spectral regions incident on that filter. A generalized approach compares magnitudes in different bands for the nearby and distant supernova, bands that are selected to give sensitivity in corresponding regions of the redshifted and unredshifted spectra. Thus at a redshift of $z \approx 0.5$, local $B$ magnitudes are compared with distant $R$ magnitudes. We compute these generalized $K$ corrections over a range of redshifts and bandpass pairs and discuss their advantages over the traditional single-band $K$ correction. In particular, errors near maximum light can be kept below 0.05 mag out to at least $z=0.6$, whereas the traditional $K$ correction is difficult to use beyond $z > 0.2$.

Security in power system state estimation
Creators: name: Majumdar, Ankur
Publisher: name: Imperial College London
Year: 2016

description: With the power system evolving from passive to a more active system there is an incorporation of information and communication infrastructures in the system. The measurement data are more prone to tampering from attackers for mala fide intentions. Therefore, security and reliability of distribution have become major concerns. State estimation (SE), being the core function of the energy/distribution management system (EMS/DMS), has become necessary in order to operate the system efficiently and in a controlled manner. Although SE is a well-known task in transmission systems, it is usually not a common task in unbalanced distribution systems due to the difference in design and operation philosophy. This thesis addresses these issues and investigates the distribution system state estimation with unbalanced full three-phase modelling. The formulation, based on weighted least squares estimation, is extended to include the open/closed switches as equality constraints. This research then explores the vulnerabilities of the state estimation problem against attacks associated with leverage measurements. Detecting gross error particularly for leverage measurements have been found to be difficult due to low residuals. The thesis presents and discusses the suitability of externally studentized residuals compared to traditional residual techniques. Additionally, the masking/swamping phenomenon associated with multiple leverages makes the identification of gross error even more difficult. This thesis proposes a robust method of identifying the high leverages and then detecting gross error when the leverage measurements are compromised. All algorithms are validated in different IEEE test systems.

description: We discuss the properties of the Seyfert 1.5 galaxy LB 1727, also known as 1H 0419-577, from X-ray observations obtained by ASCA and ROSAT along with optical observations from earlier epochs. ASCA shows only modest (< 20%) variations in X-ray flux within or between the observations. In contrast, a daily monitoring campaign over 1996 Jun - Sept by the ROSAT HRI instrument reveals the soft X-ray (0.1-2 keV) flux to have increased by a factor ~3. The 2 - 10 keV continuum can be parameterized as a power-law with a photon index Gamma ~ 1.45-1.68 across ~0.7 - 11 keV in the rest-frame. We also report the first detection of iron Kalpha line emission in this source. Simultaneous ASCA and ROSAT data show the X-ray spectrum to steepen sharply at a rest-energy \~0.75 keV, the spectrum below this energy can be parameterized as a power-law of slope Gamma ~3.6. We show that LB 1727 is one of the few Seyferts for which we can rule out the possibility that the presence of a warm absorber is solely responsible for the spectral steepening in the soft X-ray regime. Consideration of the overall spectral-energy-distribution for this source indicates the presence of a pronounced XUV-bump visible in optical, ultraviolet and soft X-ray data.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

Effects of non-linear vacuum electrodynamics on the polarization plane of light

description: We consider the Pleba{ń}ski class of nonlinear theories of vacuum electrodynamics, i.e., Lagrangian theories that are Lorentz invariant and gauge invariant. Our main goal is to derive the transport law of the polarization plane in such a theory, on an unspecified general-relativistic spacetime and with an unspecified electromagnetic background field. To that end we start out from an approximate-plane-harmonic-wave ansatz that takes the generation of higher harmonics into account. By this ansatz, the electromagnetic field is written as an asymptotic series with respect to a parameter $α$, where the limit $α\to 0$ corresponds to sending the frequency to infinity. We demonstrate that by solving the generalized Maxwell equations to zeroth and first order with respect to $α$ one gets a unique transport law for the polarization plane along each light ray. We exemplify the general results with the Born-Infeld theory.

Gravitational Radiation during Thorne-Zytkow object formation

description: Calculation of gravitational radiation during binary inspiral leading to possible formation of a Thorne-Zytkow (TZ) object (a neutron star inside a supergiant core) is performed. The calculations were done for polytropic density distributions with different indeces $n$, as well as for realistic models of supergiants. A maximum frequency of the emitted gravitational waves during this process was found to range from a few to 300 initial keplerian orbital frequensies, that is from $10^{-5}$ to $\sim 0.1$ Hz, depending on the model. A dimensionless strain metric amplitude can reach $h\sim 10^{-23.5}$ for a source lying 10 kpc away from the Sun. We conclude that TZ objects forming at a rate of 1 per 500 yrs in the Galaxy could be potential astrophysical targets for space laser intereferometers. Analysis of gravitational waveforms emitted during TZ-object formation could bring a unique information about stellar structure.

Physiological studies investigating the actions of novel reproductive hormones

Publisher: name: Imperial College London
Year: 2016

description: Infertility is becoming increasingly more common, affecting 1 in 6 couples in the UK and an estimated 48.5 million couples worldwide. Although there are a number of hormonal treatments, there has been very little advance in new treatments in the last decade. However, assisted reproductive therapies including in vitro fertilisation (IVF) are being more commonly used and in fact 2% of babies were conceived in the UK through IVF in 2012, although the average pregnancy rate per cycle has remained stable at only 20% for several years. Therefore, there is a huge scope for developing new treatments to help with the rising problem of infertility. Kisspeptin is a hypothalamic hormone that was associated for the first time with reproduction in 2003 and is now emerging as a possible novel future therapeutic for reproductive and fertility disorders. Kisspeptin signalling is vital for normal reproductive function and critically regulates GnRH secretion in response to metabolic and environmental cues. Previous research studies have shown that kisspeptin can be administered safely to humans with no side effects and therefore, my research builds on this previous work. I have focused on investigating how best to optimise the use of kisspeptin for future therapy, by firstly examining which isoform of kisspeptin is more potent and how this compares to GnRH (a current treatment modality). Secondly, I investigated whether continuous subcutaneous administration of kisspeptin would be a viable treatment modality, as in the future kisspeptin could be administered in a subcutaneous pump device and managed at home by the patient. I also investigate how baseline oestradiol levels may influence the gonadotrophin response to kisspeptin. Lastly, I investigate how kisspeptin interacts with two other neuropeptides to affect gonadotrophin secretion, by coadministration of them in healthy males.

description: We complement a recent work on the stability of fixed points of the CMC-Einstein-$Λ$ flow. In particular, we modify the utilized gauge for the Einstein equations and remove a restriction on the fixed points whose stability we are able to prove by this method, and thereby generalize the stability result. In addition, we consider the notion of the reduced Hamiltonian, originally introduced by Fischer and Moncrief for the standard CMC-Einstein flow. For the analog version of the flow in the presence of a positive cosmological constant we identify the stationary points and relate them to the long-time behavior of the flow on manifolds of different Yamabe types. This entails conjectures on the asymptotic behaviour and potential attractors.

Applications of metal oxides in the contact systems of organic electronic devices
Creators: name: Lofts, Edward
Publisher: name: Imperial College London
Year: 2015

description: Metal oxides are a group of materials that have shown great promise in improving the efficiency of devices based on organic materials through inclusion in the contact structures of such devices. In this work, the deposition technique of spray pyrolysis is developed for use for the deposition of doped zinc oxide films and molybdenum oxide films. Spray pyrolysis is of great interest as a technique for use in the organic electronics field due to its cost, scalability and compatibility with other solution processing techniques. This makes the technique particularly interesting for use in devices intended for large scale applications such as lighting The study of doped zinc oxide focuses on its application as an alternative transparent conducting layer to the standard indium tin oxide layer. The zinc oxide layer was doped with aluminium to increase its conductivity, and the effect of lithium doping was investigated with the intent of improving the conductivity of the layers further. Annealing of the layers in a nitrogen environment was found to produce layers of a similar conductivity to that of indium tin oxide and the lithium doping was found to result in higher conductivities in annealed layers. The study of molybdenum oxide focuses on its application as a hole injection layer included in the anode contact of organic light emitting diodes. The deposition temperature was found to have a large effect on the resulting device efficiencies. This effect was determined to be due to variation of the work function and ion ratios present in the molybdenum oxide layer with deposition temperature. This work resulted in the fabrication of devices with efficiencies double that of the standard solution processed hole injection layer.

description: We propose a method for fast, deterministic resonator reset based on tunable dissipative modes. The dissipator is based on a Josephson junction with relatively low quality factor. When the dissipator is tuned into resonance with a high quality microwave resonator, resonator photons are absorbed by the dissipator at a rate orders of magnitude faster than the resonator relaxation rate. We determine the optimal parameters for realization of the tunable dissipator, and examine application of the dissipator to removing spurious photon population in the qubit readout resonator in circuit quantum electrodynamics. We show that even in the nonlinear large photon occupation regime, this enhanced resonator decay rate can be attained by appropriate modulation of the dissipator frequency.

Poincaré type Kähler metrics and stability on toric varieties
Creators: name: Sektnan, Lars Martin
Publisher: name: Imperial College London
Year: 2016

description: In this thesis we study the relationship between the existence of extremal Kähler metrics and stability. We introduce a space of symplectic potentials for toric manifolds, which we show gives metrics with mixed Poincaré type and cone angle singularities. We show uniqueness and that existence implies stability for extremal metrics arising from these potentials. For quadrilaterals, we give a computable criterion for stability in certain cases, giving a definite log-stable region for generic quadrilaterals. We use computational tools to find new examples of stable and unstable toric manifolds. For Poincaré type manifolds with an S1-action, we prove a version of the LeBrun-Simanca openness theorem and Arezzo-Pacard blow-up theorem.
Conjugated polymer-metal complexes for organic electronics

description: Organometallic complexes play a crucial role in Organic Electronics and due to their interesting optoelectronic properties they have been widely applied in organic light-emitting diodes and organophotovoltaic devices. Organometallic complexes are often used in the form of small molecules and their exact orientation in the bulk material can have a major effect on device performance. In this work, different approaches of covalently incorporating metal-porphyrin complexes into polymers were explored with the aim of producing homogeneous donor-acceptor type polymers which allow for the elimination of phase separation effects within the active material of the respective devices. A set of design rules was developed for the creation of porphyrin-polymer complexes and their application as host-guest systems in the triplet-sensitisation of semi-conducting polymers was studied, determining the optimal functional groups as well as matching absorption and emission properties. To this end, a synthesis pathway was developed that enabled the creation of metal porphyrins as well as their specific functionalisation for use in different co-polymerisation reactions. Platinum (II), palladium (II) and zinc (II) porphyrins were synthesised and successfully incorporated into a series of semi-conducting polymers: regiorandom and regioregular poly(3-hexylthiophene) (P3HT), poly(bis(decylthiophene)phenylene) (TTP) and poly(para-phenylenevinylene) (PPV). Successful co-polymerisation was reported for all polymers and the electronic interaction between the polymer hosts and porphyrin guests was analysed. The successful creation of triplet-sensitised polymers was shown and the full triplet formation pathway was mapped by spectroscopic means, creating a novel tool for the generation and analysis of polymer triplet excitons. Finally, computational methods were used for the accurate description of polymer triplet excited states and their usefulness in the prediction of excited state properties was shown. Polymer models were designed, computed and compared to experimental data and the use of computational methods as a widely applicable and precise tool for determining polymer excited states was discussed, further substantiating the design rules developed throughout this work.

description: We present a photometric catalog (based on V and I photometry) of galaxies in the central regions of the Fornax galaxy cluster. Our 11 CCD fields cover 0.17 degrees in total. The limiting surface brightness is around 24 mag arsec^-2, similar to that of Ferguson's (1989, AJ 98, 367) catalog, whereas our limiting total magnitude is around V = 22 mag, about two magnitudes fainter. It is the surface brightness limit, however, that prevents us from detecting the counterparts of the faintest Local Group dwarf spheroidals. The photometric properties of all objects are presented as a catalog. The properties and fit parameters of the surface brightness profiles for a sub-sample are presented as a second catalog (both catalogs are available in electronic form at the CDS). We can only add 4 new dwarf galaxies to Ferguson's catalog. However, we confirm that the dwarf galaxies in Fornax follow a similar surface brightness-magnitude relation as the Local Group dwarfs. They also follow the color (metallicity) - relation seen in other galaxy clusters. A formerly suspected excess of dwarf galaxies surrounding the central cD galaxy NGC 1399 can finally be ruled out. An enhanced density of objects around NGC 1399 can indeed be seen, but it appears displaced with respect to the central galaxy and is identified as a background cluster at z = 0.11 in Paper II of these series, which will discuss spectroscopic results for our sample.

The influence of MAIT cells and host genomic risk factors on dengue infection

Publisher: name: Imperial College London

description: Dengue virus (DENV) is a rapidly emerging pathogen causing an estimated 100 million symptomatic infections annually. The clinical spectrum of dengue disease is broad ranging from asymptomatic to death. Factors contributing to differential outcome of DENV disease are not entirely understood. However, variation in host genetics and in the immune response are thought to play an important role in dengue pathogenesis. In this thesis, the influence of host genetics and of a recently discovered unconventional T cell, called Mucosal Associated Invariant T (MAIT) cell, on DENV infection were investigated. MAIT cells are abundant in humans and recognise bacterial ligands. For the first time, activation of MAIT cells was observed during a human viral infection in vivo and in vitro. This activation was TCR independent but dependent on IL-18. Furthermore, levels of IL-18 and MAIT cell activation correlated with disease severity in DENV infected patients. Upon activation, MAIT cells were able to enhance or inhibit DENV infection of various target cells in vitro mediated by IFN-γ. These findings suggest a possible mechanism for how MAIT cell activation may contribute to both antiviral defence and immunopathology during DENV infection. As high viremia is associated with disease severity, the influence of host genetic variants on the susceptibility of two target cells – primary human DCs and macrophages - on DENV infection was investigated using a systems genetics approach. In DCs and macrophages, expression levels of 93 and 3 genes showed strong correlations with the inter-individual variation in infection rates, respectively. These results may lead to the discovery of unknown host genomic risk factors for DENV susceptibility. Overall, understanding the role of MAIT cells during DENV infection as well as identifying new host genomic risk factors for DENV susceptibility are crucial to better understand dengue pathogenesis and may help generate therapeutic agents in the future.

description: We explore a series expansion method to calculate the modes of oscillations for a variety of uniformly rotating finite disks, either with or without a dark halo. Since all models have the same potential, this survey focuses on the role of the distribution function in stability analyses. We show that the stability behaviour is greatly influenced by the structure of the unperturbed distribution, particularly by its energy dependence. In addition we find that uniformly rotating disks with a halo in general can feature spiral-like instabilities.

Deterministic global optimisation and location of transition states
Creators: name: Nerantzis, Dimitrios
Publisher: name: Imperial College London
Year: 2016

description: Transition states (index-1 saddle points) play a crucial role in determining the rates of chemical transformations but their reliable identification remains challenging in many applications. Deterministic global optimization methods have previously been employed for the location of transition states (TSs) by initially finding all stationary points and then identifying the TSs among the set of solutions. We propose several regional tests, applicable to general nonlinear, twice continuously differentiable functions, to accelerate the convergence of such approaches by identifying areas that do not contain any TS or that may contain a unique TS. The tests are based on the application of the interval extension of theorems from linear algebra to an interval Hessian matrix. They can be used within the framework of global optimization methods with the potential of reducing the computational time for TS location. We present the theory behind the tests, discuss their algorithmic complexity and show via a few examples that significant gains in computational time can be achieved by using these tests. Next, we present and explore the behaviour of a branch-and-bound algorithm for calculating valid bounds on the k-th largest eigenvalue of a symmetric interval matrix. Branching on the interval elements of the matrix takes place in conjunction with the application of Rohn’s method (an interval extension of Weyl’s theorem) in order to obtain valid outer bounds on the eigenvalues. Inner bounds are obtained with the use of two local search methods. The algorithm has the theoretical property that it provides bounds to any arbitrary precision ε > 0 (assuming infinite precision arithmetic) within finite time. In contrast with existing methods, bounds for each individual eigenvalue can be obtained even if its range overlaps with the ranges of other eigenvalues. Performance analysis is carried out through various examples. Finally, we present a refinement method in order to improve (reduce) the α values given by the scaled Gerschgorin method and thus create tighter convex underestimators. We apply the new method and compare it with the scaled Gerschgorin method on a number of test interval symmetric matrices. Although in the experiments we use the scaled Gerschgorin method the refinement algorithm can be utilized to improve the α values of any other method as well.

description: Radial velocities of 94 galaxies brighter than about V_tot = 20 mag in the direction of the central Fornax cluster have been measured. Except for 8 Fornax members, all galaxies lie in the background. Among the 8 members, there are 5 nucleated dwarf ellipticals that are already listed in the FCC (Ferguson 1989, AJ 98, 367). Two of the 3 ``new'' members are very compact and have surface brightnesses comparable to globular clusters, however their luminosities are in the range of dwarf elliptical nuclei. The measured line indices (especially Mg2, H beta, and iron) of the brighter of the compact objects suggest a solar metallicity, whereas the fainter compact object as well as the dE,Ns have line indices that are similar to those of old metal-poor globular clusters (GCs). However, with these data it is not possible to clearly classify the compact objects either as very bright globular clusters, isolated nuclei of dE,Ns, or even compact ellipticals. A background galaxy cluster at z = 0.11 has been found just behind the center of the Fornax cluster. This explains the excess population of galaxies reported in Paper I. The brightest galaxy of the background cluster lies only 1.1 arcmin south of NGC 1399 and is comparable in absolute luminosity with the central Fornax galaxy itself.

New generation of effective core potentials from correlated calculations: 2nd row elements

description: Very recently, we have introduced correlation consistent effective core potentials (ccECPs) derived from many-body approaches with the main target being its use in explicitly correlated methods but also in mainstream approaches. The ccECPs are based on reproducing excitation energies for a subset of valence states, i.e., achieving a near-isospectrality between the original and pseudo Hamiltonians. In addition, binding curves of dimer molecules have been used for refinement and overall improvement of transferability over a range of bond lengths. Here we apply similar ideas to the second row elements and study several aspects of the constructions in order to find the optimal (or nearly-optimal) solutions within the chosen ECP forms with $3s,3p$ valence space (Ne-core). New constructions exhibit accurate low-lying atomic excitations and equilibrium molecular bonds (on average within $\approx$ $0.03$ eV and $3$ mÅ), however, the errors for Al and Si oxide molecules at short bond lengths are notably larger for both ours and existing ECPs. Assuming this limitation, our ccECPs show a systematic balance between the criteria of atomic spectra accuracy and transferability for molecular bonds. In order to provide another option with much higher uniform accuracy, we also construct He-core ECPs for the whole row with typical discrepancies of $\approx$ 0.01 eV or smaller.
