description: We investigate the compatibility of cosmological constraints on inflation and the cosmological constant with the asymptotic safety scenario of quantum gravity. The effective action is taken to be of $f(R)$ form, truncated to second order. The flow generated by the Functional Renormalisation Group Equation is analysed and it is found to allow for trajectories that are compatible with the observational constraints on the parameters of the action, both at early and late cosmological times. In particular, the gravitational effective dynamics generated in the trans-Planckian regime flows to Starobinsky inflation at early times and to standard Einstein Gravity with a cosmological constant at late times. Moreover, the cosmological constant acquires an energy dependence at $10^{-2}$ eV, increasing from its current value of $10^{-66} \,\text{eV}^{2}$ on Hubble scale to a value of $10^{30}\, \text{eV}^{2}$ at inflation scale.

description: The Bhatnagar-Gross-Krook (BGK) model as well as its extensions (ellipsoidal statistical BGK, Shakhov BGK, unified BGK) are used in particle-based fluid dynamics and compared with the Direct Simulation Monte Carlo (DSMC) method. To this end, different methods are investigated that allow efficient sampling of the Shakhov and the unified target distribution functions. As a consequence, particle simulations based on the Shakhov BGK and the unified BGK model are possible in an efficient way. Furthermore, different energy conservation schemes are tested for the BGK models. It is shown that the choice of the energy conservation scheme has a major impact on the quality of the results for each model. The models are verified with a Couette flow problem at different Knudsen numbers and wall velocities. Furthermore, the models are compared with DSMC results of a hypersonic flow around a 70$^\circ$ blunted cone. It is shown that the unified BGK model is able to reproduce rarefied gas phenomena. Furthermore, it is shown that the difference in the reproduction of shock structure is not significant between the ellipsoidal statistical BGK and Shakhov BGK model for the flow around a 70$^\circ$ blunted cone and significantly depends on the energy conservation method. The choice of the energy conservation method is especially crucial for the Shakhov model whereas the ellipsoidal statistical BGK model is much more robust concerning the energy conservation scheme. Additionally, a computational time study is done to show the efficiency of BGK-based simulations for low Knudsen number flows compared with DSMC.

description: Suppose $X$ and $Y$ are finite complexes, with $Y$ simply connected. Gromov conjectured that the number of mapping classes in $[X,Y]$ which can be realized by $L$-Lipschitz maps grows asymptotically as $L^α$, where $α$ is an integer determined by the rational homotopy type of $Y$ and the rational cohomology of $X$. This conjecture was disproved in a recent paper of the author and Weinberger; we gave an example where the `predicted' growth is $L^8$ but the true growth is $L^8\log L$. Here we show, via a different mechanism, that the universe of possible such growth functions is quite large. In particular, for every rational number $r \geq 4$, there is a pair $X,Y$ for which the growth of $[X,Y]$ is essentially $L^r$.

Search for pair and single production of vectorlike quarks in final states with at least one $Z$ boson decaying into a pair of electrons or muons in $pp$ collision data collected with the ATLAS detector at $\sqrt{s} = 13$ TeV

description: A search for vectorlike quarks is presented, which targets their decay into a $Z$ boson and a third-generation Standard Model quark. In the case of a vectorlike quark $T$ ($B$) with charge $+2/3e$ ($-1/3e$), the decay searched for is $T \rightarrow Zt$ ($B \rightarrow Zb$). Data for this analysis were taken during 2015 and 2016 with the ATLAS detector at the Large Hadron Collider and correspond to an integrated luminosity of 36.1 fb$^{-1}$ of $pp$ collisions at $\sqrt{s} = 13$ TeV. The final state used is characterized by the presence of $b$-tagged jets, as well as a $Z$ boson with high transverse momentum, which is reconstructed from a pair of opposite-sign same-flavor leptons. Pair and single production of vectorlike quarks are both taken into account and are each searched for using optimized dileptonic exclusive and trileptonic inclusive event selections. In these selections, the high scalar sum of jet transverse momenta, the presence of high-transverse-momentum large-radius jets, as well as - in the case of the single-production selections - the presence of forward jets are used. No significant excess over the background-only hypothesis is found and exclusion limits at 95% confidence level allow masses of vectorlike quarks of $m_T > 1030$ GeV ($m_T > 1210$ GeV) and $m_B > 1010$ GeV ($m_B > 1140$ GeV) in the singlet (doublet) model. In the case of 100% branching ratio for $T\rightarrow Zt$ ($B\rightarrow Zb$), the limits are $m_T > 1340$ GeV ($m_B > 1220$ GeV). Limits at 95% confidence level are also set on the coupling to Standard Model quarks for given vectorlike quark masses.

description: We present the results of three years of ground-based observations of the Seyfert 1 galaxy NGC 5548, which combined with previously reported data, yield optical continuum and broad-line H-beta light curves for a total of eight years. The light curves consist of over 800 points, with a typical spacing of a few days between observations. During this eight-year period, the nuclear continuum has varied by more than a factor of seven, and the H-beta emission line has varied by a factor of nearly six. The H-beta emission line responds to continuum variations with a time delay or lag of 10-20 days, the precise value varying somewhat from year to year. We find some indications that the lag varies with continuum flux in the sense that the lag is larger when the source is brighter.

A rate-splitting approach to multiple-antenna broadcasting
Creators: name: Joudeh, Hamdi
Publisher: name: Imperial College London
Year: 2016

description: Signal processing techniques for multiple-antenna transmission can exploit the spatial dimension of the wireless channel to serve multiple users simultaneously, achieving high spectral efficiencies. Realizing such gains; however, is strongly dependent on the availability of highly accurate and up-to-date Channel State Information at the Transmitter (CSIT). This stems from the necessity to deal with multiuser interference through preprocessing; as receivers cannot coordinate in general. In wireless systems, CSIT is subject to uncertainty due to estimation and quantization errors, delays and mismatches. This thesis proposes optimized preprocessing techniques for broadcasting scenarios where a multi-antenna transmitter communicates with single-antenna receivers under CSIT uncertainties. First, we consider a scenario where the transmitter communicates an independent message to each receiver. The most popular preprocessing techniques in this setup are based on linear precoding (or beamforming). Despite their near-optimum rate performances when highly accurate CSIT is available, we show that such techniques exhibit severe losses under CSIT uncertainties, even when optimally designed. We depart from this conventional approach and adopt an unorthodox transmission strategy based on Rate-Splitting (RS), which relies on broadcasting a common data stream on top of the private data streams precoded using partial CSIT. We propose an average Weighted Minimum Mean Square Error (WMMSE) algorithm to maximize the ergodic sum-rate performance. While the ergodic sum-rate measure captures the long-term overall performance, it is not well suited for delay-limited or fairness based transmissions. Hence, we generalize the RS strategy to formulate the problem of achieving robust max-min fairness over one random fading state under a bounded CSIT uncertainty model. We derive new performance limits in terms of the symmetric-DoF under heterogeneous CSIT qualities across users to identify the RS gains. Then, a robust WMMSE algorithm based on the cutting-set method is proposed to solve the semi-infinite optimization problem. This framework is extended to address the problem of power minimization under Quality of Service (QoS) constraints. Finally, we consider the problem of achieving max-min fairness in a multigroup multicasting scenario, where each message is intended to a group of users. We assume perfect CSIT in this setup, where the presence of multiple users in each group is thought of as a source of (finite) uncertainty. The DoF performance of conventional beamforming techniques are derived from which their limitations are identified. The RS strategy is then extended to this scenario, where we show that significant DoF gains can be achieved. The RS precoder optimization problem in this setup is then solved using the WMMSE approach.
Spectral Classification of Galaxies Along the Hubble Sequence

description: We develop a straightforward and quantitative two-step method for spectroscopically classifying galaxies from the low signal-to-noise (S/N) optical spectra typical of galaxy redshift surveys. First, using χ^2-fitting of characteristic templates to the object spectrum, we determine the relative contributions of the old stellar component, the young stellar component, and various emission line spectra. Then, we classify the galaxy by comparing the relative strengths of the components with those of galaxies of known morphological type. In particular, we use the ratios of (1) the emission line to absorption line contribution, (2) the young to old stellar contribution, and (3) the oxygen to hydrogen emission line contribution. We calibrate and test the method using published morphological types for 32 galaxies from the long-slit spectroscopic survey of Kennicutt (1992) and for 304 galaxies from a fiber spectroscopic survey of nearby galaxy clusters. From an analysis of a sample of long-slit spectra of spiral galaxies in two galaxy clusters, we conclude that the majority of the galaxies observed in the fiber survey are sufficiently distant that their spectral classification is unaffected by aperture bias. Our spectral classification is consistent with the morphological classification to within one type (e.g. E to S0 or Sa to Sb) for \gtsim 80% of the galaxies. Disagreements between the spectral and morphological classifications of the remaining galaxies reflect a divergence in the correspondence between spectral and morphological types, rather than a problem with the data or method.

How Rare Are Extraterrestrial Civilizations and When Did They Emerge?

Subjects: subject: Astrophysics (astro-ph)

description: It is shown that, contrary to an existing claim, the near equality between the lifetime of the sun and the timescale of biological evolution on earth does not necessarily imply that extraterrestrial civilizations are exceedingly rare. Furthermore, on the basis of simple assumptions it is demonstrated that a near equality between these two timescales may be the most probable relation. A calculation of the cosmic history of carbon production which is based on the recently determined history of the star formation rate suggests that the most likely time for intelligent civilizations to emerge in the universe, was when the universe was already older then about 10 billion years (for an assumed current age of about 13 billion years).

Events in which individual textures become fully wound are rare. The energy density is dominated by the more numerous partially wound configurations, with median topological charge alpha ~ 0.44. This verifies the recent supposition (Borrill et al. 1994) that such partially wound configurations should dominate the cosmic microwave background.

A New Measure of the Clustering of QSO Heavy-Element Absorption-Line Systems

Publisher: name: arXiv
Year: 1998

description: We examine the line-of-sight clustering of QSO heavy-element absorption-line systems, using a new measure of clustering, called the reduced second moment measure, that directly measures the mean over-density of absorbers. While closely related to other second-order measures such as the correlation function or the power spectrum, this measure has a number of distinct statistical properties which make possible a continuous exploration of clustering as a function of scale. From a sample of 352 C IV absorbers with median redshift 2.2, drawn from the spectra of 274 QSOs, we find that the absorbers are strongly clustered on scales from 1 to 20 Mpc. Furthermore, there appears to be a sharp break at 20 Mpc, with significant clustering on scales up to 100 Mpc in excess of that which would be expected from a smooth transition to homogeneity. There is no evidence of clustering on scales greater than 100 Mpc. These results suggest that strong C IV absorbers along a line of sight are indicators of clusters and possibly superclusters, a relationship that is supported by recent observations of ``Lyman break'' galaxies.

Pseudo-differential calculus on generalized motion groups
Creators: name: Nguyen, Binh-Khoi
Publisher: name: Imperial College London
Year: 2016

description: In recent years, effort has been put into following the ideas of M. Ruzhansky and V. Turunen to construct a global pseudo-differential calculus on Lie groups. By this, we mean a collection of operators containing the left-invariant differential calculus with the additional requirement that it be stable under composition and adjunction. Moreover, we would like these operators to have adequate boundedness properties between Sobolev spaces. Our approach consists in using the group Fourier transform to defne a global, operator-valued symbol, yielding pseudo-differential operators via an analogue of the Euclidean Kohn-Nirenberg quantization. The present document treats the case of the Euclidean motion group, which is the smallest subset of Euclidean affne transformations containing translations and rotations. As our representations are infnite-dimensional, the proofs of the calculus properties are more naturally carried out on the kernel side, which means that particular care is required to treat the singularity at the origin. The key argument is a density result which allows us to approximate singular kernels via smooth ones and is proved herein via purely spectral arguments without using classical estimates on the heat kernel.

Single-molecule DNA detection in nanopipettes using high-speed measurements and surface modifications
Creators: name: Fraccari, Raquel Leh-Na
Publisher: name: Imperial College London
Year: 2016

description: Inspired by transmembrane pores found in cell membranes and the operating principle of the Coulter counter used for cell counting, nanopore biosensors have emerged as a tool for single-molecule detection. This thesis describes single-molecule DNA detection through resistive pulse sensing using nanopipettes, a novel subclass of solid-state nanopores. In the first part of this thesis, double-stranded (ds) DNA-nanopipette surface interactions were probed in 1 M KCl electrolyte using DNA molecules with lengths ranging from 48.5 to 4 kilobase pair (kbp). A custom-built current amplifier was employed for low-noise and high-bandwidth measurements. Results from these experiments were used to theoretically rationalise DNA-surface interactions and suggest that dsDNA adsorption to the nanopipette surface prior to translocation through the pore is likely to be an important factor in the process. Subsequently, initial investigations to probe DNA-surface interactions were carried out by modifying the surface charge of nanopipettes using silanes. Additionally, experiments were performed to detect shorter dsDNA lengths. In 1 M KCl electrolyte, 200 base pair (bp) long dsDNA was successfully detected using the low-noise and high-bandwidth current amplifier. However detection of 100 bp long dsDNA required the use of 2 or 4 M LiCl electrolyte. Attention was finally shifted to the detection of 100 bp dsDNA in 1 M KCl electrolyte using functionalised lipid bilayer coated nanopipettes. Additional techniques were employed to prepare and characterise the lipid bilayers, including atomic force microscopy (AFM) and dynamic light scattering (DLS). The promising preliminary results provide a framework for further experiments using functionalised lipid bilayers to coat nanopipettes. Overall, results of the aforementioned research presented in this thesis demonstrate high-speed single-molecule detection of DNA and provide novel insights into the translocation dynamics of DNA molecules in nanopipettes and the sensing capabilities of nanopipettes.
Studies on modal logics of time and space
Creators: name: Gatto, Alberto
Publisher: name: Imperial College London
Year: 2016

description: This dissertation presents original results in Temporal Logic and Spatial Logic. Part I concerns Branching-Time Logic. Since Prior 1967, two main semantics for Branching-Time Logic have been devised: Peircean and Ockhamist semantics. Zanardo 1998 proposed a general semantics, called Indistinguishability semantics, of which Peircean and Ockhamist semantics are limit cases. We provide a finite axiomatization of the Indistinguishability logic of upward endless bundled trees using a non-standard inference rule, and prove that this logic is strongly complete. In Part II, we study the temporal logic given by the tense operators F for future and P for past together with the derivative operator , interpreted on the real numbers. We prove that this logic is neither strongly nor Kripke complete, it is PSPACE-complete, and it is finitely axiomatizable. In Part III, we study the spatial logic given by the derivative operator and the graded modalities {<>n | n in N}. We prove that this language, call it L, is as expressive as the first-order language Lt of Flum and Ziegler 1980 when interpreted on T3 topological spaces. Then, we give a general definition of modal operator: essentially, a modal operator will be defined by a formula of Lt with at most one free variable. If a modal operator is defined by a formula predicating only over points, then it is called point-sort operator. We prove that L, even if enriched with all point-sort operators, however enriched with finitely many modal operators predicating also on open sets, cannot express Lt on T2 spaces. Finally, we axiomatize the logic of any class between all T1 and all T3 spaces and prove that it is PSPACE-complete.
Credit modelling and regime-switching
Creators: name: Bell, Richard
Publisher: name: Imperial College London
Year: 2015

description: This thesis is concerned with some issues arising in relation to the capital structure and pricing of credit risk of a firm partly financed by debt. Three related models are presented. The first extends the existing literature on structural credit models of firms financed by the so called roll-over debt structure to allow for dependence between interest rates, asset volatility and the probability of default by incorporating regimes via the introduction of a Markov chain. The asset returns of a firm are modelled by a regime-switching geometric Brownian motion. An optimised capital structure is generated and the associated credit spreads analysed. The second model adds to recent work on regime-switching in the case of consol, or infinite maturity debt, by incorporating jumps into the asset process. The asset process of the firm is modelled as a phase-type Lévy process which affords a flexible framework capable of accommodating a wide range of stochastic dynamics. An optimal capital structure is identified. The contribution of the first two models is that that they are highly flexible and allow for an arbitrary number of market regimes to be combined in an intuitive way. The final model extends the literature on endogenous default to a firm which is partly financed by a single finite maturity bond. The assets of the firm are modelled as a geometric Brownian motion which pays a continuous dividend. By solving the associated optimal stopping problem, a default boundary is characterised in terms of an integral equation.
Viscous Stability of Relativistic Keplerian Accretion Disks

Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We investigate the viscous stability of thin, Keplerian accretion disks in regions where general relativistic (GR) effects are essential. For gas pressure dominated (GPD) disks, we show that the Newtonian conclusion that such disks are viscously stable is reversed by GR modifications in the behaviors of viscous stress and surface density over a significantly large annular region not far from the innermost stable orbit at $r=\rms$. For slowly-rotating central objects, this region spans a range of radii $14\lo r\lo 19$ in units of the central object's mass $M$. For radiation pressure dominated (RPD) disks, the Newtonian conclusion that they are viscously unstable remains valid after including the above GR modifications, except in a very small annulus around $r\approx 14M$, which has a negligible influence. Inclusion of the stabilizing effect of the mass-inflow through the disk's inner edge via a GR analogue of Roche-lobe overflow adds a small, stable region around \rms~for RPD disks, but leaves GPD disks unchanged. We mention possible astrophysical relevance of these results, particularly to the high-frequency X-ray variabilities observed by the $Rossi$ $X-ray$ $Timing$ $Explorer$.

The impact of fault blocking converters on HVDC protection

description: Multiterminal High Voltage Direct Current (HVDC) systems are anticipated to enable flexible transmission of renewable energy across continents, however protection strategies for such systems are in their infancy. Fast circuit breakers have been proposed, however their implementation on a network is undecided. The protection requirements are likely to depend on both the AC/DC converter and network topologies. This thesis examines several aspects of the protection of HVDC systems, considering factors influencing circuit breaker ratings, and examining primary and backup protection philosophies. A comparison is made throughout between fault feeding and fault blocking converters, aiming to investigate the impact of fault blocking converters on HVDC protection. The ratings of HVDC circuit breakers on meshed networks are evaluated, considering factors such as the current breaking magnitude, operation time, additional inductance and energy dissipation requirements for various network and converter topologies. It is shown that the circuit breaker requirements in network areas with fault blocking converters are reduced compared to when a fault feeding converter is implemented. HVDC protection is investigated, considering primary and backup methods for several protection philosophies. The influence of the converter, network and circuit breaker topologies are examined, and the impact of the HVDC protection strategy on the connected AC systems is evaluated. It is shown that slower protection strategies using fault blocking converters might be technically feasible from both the HVDC and AC system perspectives, which could result in an effective protection strategy with a reduced requirement for circuit breakers.
Heavy Quarkonium Dissociation by Thermal Gluons at Next-to-leading Order in the Quark-Gluon Plasma

description: Using the chromo-electric dipole coupling Hamiltonian from QCD multipole expansion, we derive the dissociation cross sections of heavy quarkonia by thermal gluons at next-to-leading order (NLO, also known as inelastic parton scattering dissociation) in the Quark-Gluon Plasma (QGP) in the framework of second order quantum mechanical perturbation theory. While suffering divergence (infrared and soft-collinear divergences) in vacuum, the cross sections thus derived become finite in the QGP as rendered by the finite thermal gluon masses. In contrast to the leading order (LO, also known as gluo-dissociation) counterparts rapidly dropping off with increasing incident gluon energy, the NLO cross sections exhibits finite value toward high energies because of new phase space being opened up. We then carry out a full calculation of the dissociation rates for various charmonia and bottomonia within a non-relativistic in-medium potential model. The NLO process is shown to dominate the dissociation rate toward high temperatures when the binding energies of heavy quarkonia become smaller relative to the Debye screening mass.

Post-crisis banking in the US
Creators: name: Neumann, Niklas
Publisher: name: Imperial College London
Year: 2017

description: This dissertation contributes to the understanding of the relatively poor performance of banks and the depressed credit supply since the 2007-2009 crisis. In chapter 1, I study the role of securitisation in bank lending. I compare banks with and without access to securitisation and exploit the crash in the market for securitised products in 2007 as a shock to the ability to securitise. My results show that securitisation is associated with enhanced credit supply and lower dependence on capital in lending, giving rise to a capital relief channel. Furthermore, I find evidence that banks use unlocked capital from the securitisation of consumer and residential credit to propel commercial lending, suggesting spill-over effects. I document that since the market crash in late 2007 and even more so after the crisis when tighter regulations kicked in, the credit supply enhancing effects of securitisation have evaporated. In chapter 2, I study the impact of post-crisis stress testing on banking. CCAR is an extremely far-reaching and costly annual stress testing exercise whose outcome directly impacts banks' capital distributions. Bank executives name CCAR as one of the main culprits for poor performance and lower credit supply. I exploit cross-sectional variation in compliance to isolate the impact of CCAR. My results confirm that participating in CCAR is associated with significantly lower profitability and that banks shed high risk-weighted assets including large lending exposures to comply with elevated CCAR-capital requirements. In chapter 3, I study the stock market response to enhanced prudential standards (EPST). I find that immediate price adjustments reflect that investors perceived EPST as relatively good news. In the longer-term, I document that stocks of banks affected by EPST strongly outperform otherwise comparable bank stocks. This outperformance suggests a prolonged learning period of investors to evaluate the impact of EPST on banks' financial performances.

Phase transitions and linear response in strongly coupled systems: A holographic approach
Creators: name: Banks, Elliot
Publisher: name: Imperial College London
Year: 2017

description: Understanding strongly coupled systems is an important area of theoretical physics, and has wide ranging applications from quantum chromodynamics to condensed matter physics. This thesis uses holographic methods to understand two particular aspects of strongly coupled systems - linear response and phase transitions. Firstly, we consider a general class of electrical black holes in Einstein-Maxwell-scalar theory, that are holographically dual to conformal eld theories at nite charge density and explicitly break translational invariance. By considering the linearised perturbations of these background black holes, we show that the DC thermoelectric conductivity of these systems can be determined by solving a set of linearised Navier-Stokes equations on the event horizon of the dual black hole. We demonstrate how to apply this framework in practice with several examples. Next, we consider this framework in the hydrodynamic limit, for the simpler case of Einstein gravity. We show that the full stress-energy response, rather than just the thermal conductivity, can be determined in this limit, and compare the results with the uid/gravity correspondence. We then consider more general hydrodynamics, and demonstrate that periodically deformed eld theories exhibit thermal back ow when a DC thermal source is applied Finally, we study black hole solutions of type IIB supergravity that describe N=4 supersymmetric Yang-Mills plasma with an anisotropic spatial deformation. We show that, by preserving additional scalar modes from the consistent truncation of IIB supergravity on the ve-sphere, these black holes have low temperature instabilities. We construct new thermodynamically preferred black hole solutions, and show that the phase transition between these black hole solution has unusual critical exponents that is not captured by the normal Landau-Ginzburg exponents. We consider various extensions to this, such as introducing a chemical potential, and construct a more complete phase diagram for the theory.

description: The COVID-19 pandemic made a significant impact on all people worldwide. Many workers were unemployed due to the closure of businesses and shutdowns of companies everywhere. Employability of the Hotel and Restaurant Management from 2015 – 2021 was the primary concern of this study to set innovations to strengthen not only the academic performances of the hospitality management students but also upskilling present and future HM students facing and serving the industry with the culture of excellence. The study reveals that most HRM graduate respondents were from the age group of 21-23 males who are single and have a college degree.  Most are employed permanently and work as waiters/waitresses/food servers. This only shows that the employability of HRM graduates from batch 2015 to 2021 is very satisfying, as they are employed in a very related job. However, some of the graduate respondents have jobs unrelated to their specialization. This will be considered as a percentage of mismatch. It is hard to cope with or get a better job during this pandemic. However, the HRM graduates made it through even the highest salary they received, ranging from the minimum wage. Though they received a minimum amount with maximum service provided, graduate respondents managed to deal with daily life challenges.

description: Effective overload control for large-scale online service system is crucial for protecting the system backend from overload. Conventionally, the design of overload control is ad-hoc for individual service. However, service-specific overload control could be detrimental to the overall system due to intricate service dependencies or flawed implementation of service. Service developers usually have difficulty to accurately estimate the dynamics of actual workload during the development of service. Therefore, it is essential to decouple the overload control from service logic. In this paper, we propose DAGOR, an overload control scheme designed for the account-oriented microservice architecture. DAGOR is service agnostic and system-centric. It manages overload at the microservice granule such that each microservice monitors its load status in real time and triggers load shedding in a collaborative manner among its relevant services when overload is detected. DAGOR has been used in the WeChat backend for five years. Experimental results show that DAGOR can benefit high success rate of service even when the system is experiencing overload, while ensuring fairness in the overload control.
