description: We reconsider the stochastic gravitational wave background spectrum produced during the first order hadronization process, in presence of ultraviolet cutoffs suggested by the generalized uncertainty principle as a promising signature towards the Planck scale physics. Unlike common perception that the dynamics of QCD phase transition and its phenomenological consequences are highly influenced by the critical temperature, we find that the underlying Planck scale modifications can affect the stochastic gravitational spectrum arising from the QCD transition without a noteworthy change in the relevant critical temperature. Our investigation shows that incorporating the natural cutoffs into MIT bag equation of state and background evolution leads to a growth in the stochastic gravitational power spectrum, while the relevant redshift of the QCD era, remains unaltered. These results have double implications from the point of view of phenomenology. Firstly, it is expected to enhance the chance of detecting the stochastic gravitational signal created by such a transition in future observations. Secondly, it gives a hint on the decoding from the dynamics of QCD phase transition.

Assembling the surface of Clostridium difficile
Creators: name: Willing, Stephanie
Publisher: name: Imperial College London
Year: 2014

description: Clostridium difficile is a Gram-positive, spore forming, obligate anaerobe and pathogen of humans. C. difficile infection (CDI) is a potentially fatal gastrointestinal disease, typically acquired following antibiotic treatment. As a serious nosocomial pathogen, C. difficile also inflicts a large economic cost on healthcare systems. The symptoms of CDI are primarily the result of two toxins, and these have been the focus of much research. However, less well understood is how C. difficile manages to colonise the gastrointestinal tract. The surface of the vegetative cell is likely to prove very important in the colonisation process. The vegetative cell is covered by a paracrystalline array known as a surface layer. There are 28 paralogues of the surface layer protein, SlpA, found on the C. difficile 630 genome; these comprise the cell wall protein family. Each protein within this family has in common a 100 amino acid motif (CWB 2; PF04122) repeated in triplicate at either the N or C-terminus. This motif is found in many species of Gram-positive bacteria, but despite being widespread nothing is known about its anchoring mechanism. This study demonstrates that the CWB 2 repeats have likely evolved into a discrete pseudo-trimer domain such that each repeat is necessary for cell wall protein anchoring. Amino acids that are conserved in the CWB 2 sequence are investigated and residues important for cell wall anchoring identified. A cell wall associated polysaccharide is identified as a ligand of the CWB 2 repeats. A genetic locus that putatively encodes for the biosynthesis of this cell wall associated polysaccharide is investigated, and aberrations in the surface layer demonstrated when these genes are knocked-down. The potential of the CWB 2 repeats to mediate lateral interactions between the surface layer protein SlpA is analysed in experiments that suggest a role for Ca2+ in surface layer assembly. Additionally, a mutant with an unusual colony morphology obtained whilst attempting to inactivate a putative cell wall biosynthesis gene is investigated, revealing a link between a transcription coupled repair factor and toxin expression.

description: Magnetohydrodynamics in divergence form describes a hyperbolic system of covariant and constraint-free equations. It comprises a linear combination of an algebraic constraint and Faraday's equations. Here, we study the problem of well-posedness, and identify a preferred linear combination in this divergence formulation. The limit of weak magnetic fields shows the slow magnetosonic and Alfven waves to bifurcate from the contact discontinuity (entropy waves), while the fast magnetosonic wave is a regular perturbation of the hydrodynamical sound speed. These results are further reported as a starting point for characteristic based shock capturing schemes for simulations with ultra-relativistic shocks in magnetized relativistic fluids.

description: Förster theory describes electronic exciton energy migration in molecular assemblies as an incoherent hopping process between donor and acceptor molecules. The rate is expressed in terms of the overlap integral between donor fluorescence and acceptor absorption spectra. Typical time scales for systems like photosynthetic antennae are on the order of a few picoseconds. Prior to transfer it is assumed that the initially excited donor molecule has equilibrated with respect to the local environment. However, upon excitation and during the equilibration phase the state of the system needs to be described by the full density matrix, including coherences between donor and acceptor states. While being intuitively clear, addressing this regime experimentally has been a challenge until the recently reported advances in Fluorescence Detected Two-Dimensional Spectroscopy (FD2DS). Here, we demonstrate using fourth order perturbation theory, the conditions for the presence of donor-acceptor coherence induced cross-peaks at zero waiting time between the first and the second pair of pulses. The approach is illustrated for a heterodimer model which facilitates an analytical solution.

description: We investigate whether models based on the assumption that jets in quasars are powered by rotating black holes can explain the observed radio dichotomy of quasars. We show that in terms of the ``spin paradigm'' models, radio-loud quasars could be objects in which the black hole's rotation rate corresponds to an equilibrium between spin-up by accretion and spin-down by the Blandford-Znajek mechanism. Radio-quiet quasars could be hosting black holes with an average spin much smaller than the equilibrium one. We discuss possible accretion scenarios which can lead to such a bimodal distribution of black hole spins.

Stability Analysis of Core-Strahl Electron Distributions in the Solar Wind

Year: 2018

description: In this work, we analyze the kinetic stability of a solar wind electron distribution composed of core and strahl subpopulations. The core is modeled by a drifting Maxwellian distribution, while the strahl is modeled by an analytic function recently derived in (Horaites et al. 2018) from the collisional kinetic equation. We perform a numerical linear stability analysis using the LEOPARD solver (Astfalk & Jenko 2017), which allows for arbitrary gyrotropic distribution functions in a magnetized plasma. We find that for typical solar wind conditions, the core-strahl distribution is unstable to the kinetic Alfvén and magnetosonic modes. The maximum growth rates for these instabilities occur at wavenumbers $k d_i \lesssim 1$, at moderately oblique angles of propagation, thus providing a potential source of kinetic-scale turbulence. In contrast with previous reports, we however do not find evidence for a whistler instability directly associated with the electron strahl. This may be related to the more realistic shape of the electron strahl distribution function adopted in our work. We therefore suggest that the whistler modes often invoked to explain anomalous scattering of strahl particles could appear as a result of nonlinear mode coupling and turbulent cascade originating at scales $k d_i \lesssim 1$.

New approaches to coccolith geochemistry and its application to Cenozoic paleoceanography
Creators: name: Prentice, Katherine Clare
Publisher: name: Imperial College London
Year: 2015

description: The use of coccolithophores has until recently been restricted mainly to biostratigraphic indicators. Their small size makes it difficult to obtain species-specific geochemical data and they are often perceived to preserve poorly compared with the larger foraminifer. In the last decade the study of potential coccolithophore bio-geochemical proxies has taken off, but with little to support their use in deep-time records. The suitability of fossil coccolithophores for geochemical proxies has been examined. A large collection of trace metal data from individual coccoliths throughout the Cenozoic has been collected, from a range of taxa. Using SIMS it has been demonstrated that the Sr/Ca values from fossil coccoliths are comparable to those collected from their modern counterparts. It has also been possible to examine the distribution of ions within individual coccoliths, revealing that their original calcite is preserved and the effects of diagenesis can often be overcome. For the first time a high-resolution record of Sr/Ca from calcareous nannofossils has been produced over the Eocene/Oligocene transition, (~34 to 33.5 Ma). This period of extreme climate change resulted in the permanent formation of ice, for the first time in the Cenozoic, at the Antarctic within ~400 ky, accompanied by a general shift to a modern climate state. This shift is associated with changes in nutrient cycling and/or ocean thermal structure due to changes in ocean circulation. It is still debated about how these changes affected productivity in the equatorial Pacific at this time. The Sr/Ca proxy provides a direct record of coccolithophore productivity. Using samples from IODP Site U1334, bulk and individual coccolithophore carbonate are examined, in combination with the coccolithophore isotopic record. The factors affecting the records are examined in detail and reveal a significant shift in productivity over the E/OT, associated with isotopic changes.

description: The dynamics of an electronic system interacting with an electromagnetic field is investigated within mixed quantum-classical theory. Beyond the classical path approximation (where we ignore all feedback from the electronic system on the photon field), we consider all electron-photon interactions explicitly according to Ehrenfest (i.e. mean-field) dynamics and a set of coupled Maxwell-Liouville equations. Because Ehrenfest dynamics cannot capture certain quantum features of the photon field correctly, we propose a new Ehrenfest+R method that can recover (by construction) spontaneous emission while also distinguishing between electromagnetic fluctuations and coherent emission.
Graphene-based membranes for fluid separations
Creators: name: Chong, Jeng Yi
Publisher: name: Imperial College London
Year: 2017

description: Graphene-based materials have attracted great interest to develop ultra-thin and high performance membranes due to their unique 2D structure, one-atomic thickness and high mechanical strength. While many studies have shown excellent performance of graphene-based membranes in fluid separations, scaling up of the membranes is still challenging. In addition, the transport mechanism in the membranes, especially in graphene oxide (GO) membranes is still not well understood. In this study, graphene-based membranes were fabricated on hollow fibre substrates as a step forward to scaling up. High performance stainless steel-ceramic hollow fibres were developed while exploring suitable membrane substrates. GO and graphene membranes were fabricated on ceramic hollow fibres using two different approaches: solution-processing to produce GO membranes and chemical vapour deposition for graphene membranes. GO membranes were found unstable on hollow fibre substrates due to drying-related shrinkage. The stability problem was overcome by introducing a sacrificial layer during membrane synthesis. A post-treatment modification was carried out to improve the water permeation of GO membranes by creating extra microstructural defects in the membranes. Meanwhile, multi-layer graphene membranes were successfully synthesized on the nickel-plated ceramic hollow fibres. The graphene layer was exceptionally inert and could serve as an excellent protection layer against corrosive chemicals. The water transport mechanisms in GO membranes in two different modes: pressure-driven filtration and pervaporation, were also studied. During filtration, GO membranes experienced a severe reduction in water permeation which was caused by the compaction of the loosely packed hierarchical microstructure. GO membranes showed a low steady state permeation flux because of the long transport path in the membranes. However, the water permeation was 1-2 orders of magnitude higher in pervaporation. The higher flux was due to the large capillary pressure in the interlayer space, which was induced by evaporation on the permeate side surface. In addition, an interface-related resistance was observed at the pore entrance of GO membranes when tested with water-ethanol mixture in pervaporation, which enabled the measurement of effective interfacial tension of miscible liquids using GO membranes.

description: We present constraints on the evolution of large-scale structure from a catalog of 710,000 galaxies with I_AB <= 24 derived from a KPNO 4m CCD imaging survey of a contiguous 4 deg x 4 deg region. The advantage of using large contiguous surveys for measuring clustering properties on even modest angular scales is substantial: the effects of cosmic scatter are strongly suppressed. We provide highly accurate measurements of the two-point angular correlation function, w(theta), as a function of magnitude on scales up to 1.5 degrees. The amplitude of w(theta) declines by a factor of ~10 over the range 16 <= I <= 20 but only by a factor of 2 - 3 over the range 20 < I <= 23. For a redshift dependence of the spatial correlation function, xi(r), parameterized as xi(r,z)=(r/r_o)^(-gamma)(1 + z)^(-[3+epsilon]), we find r_o=5.2 +/- 0.4 Mpc/h, and epsilon >= 0 for I <= 20. This is in good agreement with the results from local redshift surveys. At I > 20, our best fit values shift towards lower r_o and more negative epsilon. A strong covariance between r_o and epsilon prevent us from rejecting epsilon > 0 even at faint magnitudes but if epsilon > 1, we strongly reject r_o <= 4/h Mpc (co-moving). The above expression for xi(r,z) and our data give a correlation length of r_o(z=0.5) approx 3.0 +/- 0.4 Mpc/h, about a factor of 2 larger than the correlation length at z = 0.5 derived from the Canada--France Redshift Survey (CFRS). The small volume sampled by the CFRS and other deep redshift probes, however, make these spatial surveys strongly susceptible to cosmic scatter and will tend to bias their derived correlation lengths low. Our galaxy counts agree well with those from the HDF survey and, thus, argue against a significant inclusion of sub-galactic components in the latter census for I < 24.

description: In the present work, a highly efficient Moving Morphable Component (MMC) based approach for multi-resolution topology optimization is proposed. In this approach, high-resolution optimization results can be obtained with much less number of degrees of freedoms (DOFs) and design variables since the finite element analysis model and the design optimization model are totally decoupled in the MMC-based problem formulation. This is achieved by introducing super-elements for structural response analysis and adopting a domain decomposition strategy to preserve the topology complexity of optimized structures. Both two-and three-dimensional numerical results demonstrate that substantial computational efforts can be saved with use of the proposed approach.

Subjects: subject: Quantum Physics (quant-ph)

description: We discuss some fundamental properties of discrete system-time history states. Such states arise for a quantum reference clock of finite dimension and lead to a unitary evolution of system states when satisfying a static discrete Wheeler-DeWitt-type equation. We consider the general case where system-clock pairs can interact, analyzing first their different representations and showing there is always a special clock basis for which the evolution for a given initial state can be described by a constant Hamiltonian $H$. It is also shown, however, that when the evolution operators form a complete orthogonal set, the history state is maximally entangled for any initial state, as opposed to the case of a constant $H$, and can be generated with a simple two-clock setting. We then examine the quadratic system-time entanglement entropy, providing an analytic evaluation and showing it satisfies strict upper and lower bounds determined by the energy spread and the geodesic evolution connecting the initial and final states. We finally show that the unitary operator that generates the history state can itself be considered as an operator history state, whose quadratic entanglement entropy determines its entangling power. Simple measurements on the clock enable to efficiently determine overlaps between system states and also evolution operators at any two times.

description: We compute anomalous dimensions of higher spin operators in Conformal Field Theory at arbitrary space-time dimension by using the OPE inversion formula of \cite{Caron-Huot:2017vep}, both from the position space representation as well as from the integral (viz. Mellin) representation of the conformal blocks. The Mellin space is advantageous over the position space not only in allowing to write expressions agnostic to the space-time dimension, but also in that it replaces tedious recursion relations in terms of simple sums which are easy to perform. We evaluate the contributions of scalar and spin exchanges in the $t-$channel exactly, in terms of higher order Hypergeometric functions. These relate to a particular exchange of conformal spin $β=Δ+J$ in the $s-$channel through the inversion formula. Our exact results reproduce the special cases for large spin anomalous dimension and OPE coefficients obtained previously in the literature.

description: The NASA Kepler and K2 Missions have recently revealed a population of transiting giant planets orbiting moderately evolved, low-luminosity red giant branch stars. Here, we present radial velocity measurements of three of these systems, revealing significantly non-zero orbital eccentricities in each case. Comparing these systems with the known planet population suggests that close-in giant planets around evolved stars tend to have more eccentric orbits than those around main-sequence stars. We interpret this as tentative evidence that the orbits of these planets pass through a transient, moderately eccentric phase where they shrink faster than they circularize due to tides raised on evolved host stars. Additional radial velocity measurements of currently known systems, along with new systems discovered by the recently launched NASA TESS mission, may constrain the timescale and mass dependence of this process.

A laser-machined MEMS axial flow turbine: design, fabrication, testing and materials analysis
Creators: name: Heaton, Mark Edwin
Publisher: name: Imperial College London
Year: 2013

description: This thesis details the design, fabrication and characterisation of a 13 mm-diameter axial flow microturbine with an integrated electromagnetic generator. Axial turbine blades are not amenable to fabrication by traditional MEMS (micro-electromechanical systems) processes because they cannot be produced by machining prismatic shapes into the rotor disc; the direction of machining has to change as material is removed to produce the required blade curvature. This challenge was met by laser machining the blades with a novel moving-mask process so as to produce a step-wise approximation to the desired profile. The chosen material for making the microturbine rotor was the negative photo-resist SU-8. Once properly cured into its solid state, this polymer becomes very durable and dimensionally stable. The SU-8 was readily preformed using lithography and RIE (reactive ion etching), and was also responsive to excimer laser ablation as necessary for finishing the blade profiles. The microturbine was designed to be assembled into a stacked MEMS device comprising a rotor embedded with ten rare earth magnets sandwiched between upper and lower silicon stators carrying electroplated generator coils. Characterisation of the turbine showed that mechanical losses, mainly in the bearings, were significantly reducing the efficiency. A laser scanning vibrometer (Polytec MSA-400) was used to measure the turbine rundown time which was found to be only ~150 ms due to high bearing friction. The in-plane and out-of-plane vibration (wobble) of the rotor as it spun around on its micro roller bearings were also mapped to determine if bearing alignment was reducing power output. The out-of-plane vibration was found to be the main problem, so a new one-piece rotational support holder was constructed for the device. Some microturbine rotors were found to shatter above 100,000 rpm, and this led to interest in the mechanical properties of the cured SU-8. Firstly, PGAA (prompt gamma activation analysis) was used to measure the constituent element percentages and contaminants in a range of SU-8 samples subjected to different heat curing temperatures and UV cross-linking times. It was of interest to see how the O and H percentages changed as these are normally expected to vary depending on temperature and humidity. SANS (small angle neutron scattering) tests were also performed using a 10 MW reactor which measured sub-surface scattering for the same samples to reveal material defects.

Mechanical Effects of Radiation Pressure Quantum Fluctuations

Year: 1995
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: As revealed by space-time probing, mechanics and field theory come out as complementary descriptions for motions in space-time. In particular, quantum fields exert a radiation pressure on scatterers which results in mechanical effects that persist in vacuum. They include mean forces due to quantum field fluctuations, like Casimir forces, but also fluctuations of these forces and additional forces linked to motion. As in classical electron theory, a moving scatterer is submitted to a radiation reaction force which modifies its motional response to an applied force. We briefly survey the mechanical effects of quantum field fluctuations and discuss the consequences for stability of motion in vacuum and for position fluctuations.

Portfolio optimisation and option pricing in discrete time with transaction costs
Creators: name: Quek, Gary Sze Huat
Publisher: name: Imperial College London
Year: 2012

description: Discrete time models of portfolio optimisation and option pricing are studied under the effects of proportional transaction costs. In a multi-period portfolio selection problem, an investor maximises expected utility of terminal wealth by rebalancing the portfolio between a risk-free and risky asset at the start of each time period. A general class of probability distributions is assumed for the returns of the risky asset. The optimal strategy involves trading to reach the boundaries of a no-transaction region if the investor’s holdings in the risky asset fall outside this region. Dynamic programming is applied to determine the optimal strategy, but it can be computationally intensive. In the limit of small transaction costs, a two-stage perturbation method is developed to derive approximate solutions for the exponential and power utility functions. The first stage involves ignoring the no-transaction region and transacting to the optimal point corresponding to the zero transaction costs case. Approximations of the resulting suboptimal value functions are obtained. In the second stage, these suboptimal value functions are corrected to obtain approximations of the optimal value functions and optimal boundaries at all time steps. A discrete time option pricing model is developed based on the utility maximisation approach. This model reduces to the binomial model in the special case where the risky asset follows a binomial price process without transaction costs. Incorporating transaction costs, the utility indifference price and marginal utility indifference price of the option are observed to depend on the price of the underlying risky asset and the investor’s holdings in the risky asset. The regions where these option prices do not vary with the investor’s holdings in the risky asset are identified. An example illustrates how utility indifference pricing or marginal utility indifference pricing enables one to determine the bid and ask price of a European call option.

Excitation and Disruption of a Giant Molecular Cloud by the Supernova Remnant 3C391

description: Using the IRAM 30-m telescope, we observed the supernova remnant 3C 391 (G31.9+0.0) and its surroundings in the CO(2-1), HCO+(1-0), CS(2-1), CS(3-2), and CS(5-4) lines. The ambient molecular gas at the distance (9 kpc) of the remnant comprises a giant molecular cloud whose edge is closely parallel to a ridge of bright non-thermal radio continuum, which evidently delineates the blast-wave into the cloud. We found that in a small (0.6 pc) portion of the radio shell, the molecular line profiles consist of a narrow (2 km/s) component, plus a very wide (> 20 km/s) component. Both spectral components peak within 20" of a previously-detected OH 1720 MHz maser. We name this source 3C 391:BML (broad molecular line); it provides a new laboratory, similar to IC 443 but on a larger scale, to study shock interactions with dense molecular gas. The wide spectral component is relatively brighter in the higher-excitation lines. We interpret the wide spectral component as post-shock gas, either smoothly accelerated or partially dissociated and reformed behind the shock. The narrow component is either the pre-shock gas or cold gas reformed behind a fully dissociative shock. Using the 3 observed CS lines, we measured the temperature, CS column density, and H2 volume density in a dense clump in the parent molecular cloud as well as the wide-line and narrow-line portions of the shocked clump. The physical conditions of the narrow-line gas are comparable to the highest-density clumps in the giant molecular cloud, while the wide-line gas is both warmer and denser. The mass of compressed gas in 3C 391:BML is high enough that its self-gravity is significant, and eventually it could form one or several stars.
