description: Rivina humilis Linnaeus, Species Plantarum 1: 121. 1753.
"Habitat in Caribaeis, Jamaica, Barbados." RCN: 1006.
Lectotype (Wijnands, Bot. Commelins: 172. 1983): Herb. Clifford: 35, Rivina 1 (BM-000557794).
Generitype of Rivina Linnaeus.
Current name: Rivina humilis L. (Phytolaccaceae).
Note: Fawcett & Rendle (Fl. Jamaica 3: 156. 1914), followed by a number of later authors, indicated 163.1 (LINN) as type, but this sheet lacks Linnaeus’ Species Plantarum number (“1”) and appears to be a post-1753 addition to the collection, and not original material for the name. Smith (Fl. Vitiensis Nova 2: 262. 1981) suggested that Clifford material might make a suitable lectotype, subsequently formalised by Wijnands.

description: We study gravitational wave production during Abelian gauge-field preheating following inflation. We consider both scalar and pseudoscalar inflaton models coupled directly to Abelian gauge fields via either a dilatonic coupling to the gauge-field kinetic term or an axial coupling to a Chern-Simons term. In both cases gravitational waves are produced efficiently during the preheating phase, with a signature louder than most cosmological signals. These gravitational waves can contribute to the radiation energy budget of Universe at a level which will be probed by upcoming cosmic microwave background experiments through $N_{\rm eff}$. For axially coupled fields the resulting gravitational wave spectrum is helically polarized---a unique feature that can be used to differentiate it from other stochastic gravitational wave backgrounds. We compute the gravitational topological charge and demonstrate that gauge preheating following axion inflation may be responsible for the matter-antimatter asymmetry of the Universe via gravitational leptogenesis.

Decision support continuum paradigm for cardiovascular disease: Towards personalized predictive models
Creators: name: Tay, Darwin
Publisher: name: Imperial College London
Year: 2014

description: Clinical decision making is a ubiquitous and frequent task physicians make in their daily clinical practice. Conventionally, physicians adopt a cognitive predictive modelling process (i.e. knowledge and experience learnt from past lecture, research, literature, patients, etc.) for anticipating or ascertaining clinical problems based on clinical risk factors that they deemed to be most salient. However, with the inundation of health data and the confounding characteristics of diseases, more effective clinical prediction approaches are required to address these challenges. Approximately a few century ago, the first major transformation of medical practice took place as science-based approaches emerged with compelling results. Now, in the 21st century, new advances in science will once again transform healthcare. Data science has been postulated as an important component in this healthcare reform and has received escalating interests for its potential for ‘personalizing’ medicine. The key advantages of having personalized medicine include, but not limited to, (1) more effective methods for disease prevention, management and treatment, (2) improved accuracy for clinical diagnosis and prognosis, (3) provide patient-oriented personal health plan, and (4) cost containment. In view of the paramount importance of personalized predictive models, this thesis proposes 2 novel learning algorithms (i.e. an immune-inspired algorithm called the Evolutionary Data-Conscious Artificial Immune Recognition System, and a neural-inspired algorithm called the Artificial Neural Cell System for classification) and 3 continuum-based paradigms (i.e. biological, time and age continuum) for enhancing clinical prediction. Cardiovascular disease has been selected as the disease under investigation as it is an epidemic and major health concern in today’s world. We believe that our work has a meaningful and significant impact to the development of future healthcare system and we look forward to the wide adoption of advanced medical technologies by all care centres in the near future.

Susceptibility factors in paracetamol-induced acute liver failure
Creators: name: Possamai, Lucia
Publisher: name: Imperial College London
Year: 2015

description: Paracetamol is a popular antipyretic and analgesic medication. It is a known hepatotoxin in overdose and is the commonest cause of acute liver failure in the UK. There is significant variability in inter-individual susceptibility to the hepatotoxic effects of paracetamol, which is incompletely understood. This thesis describes work done in murine models of paracetamol-induced acute liver failure with the aim of identifying causes of variable susceptibility and understanding the immune response to liver injury. A quantitative trait locus (QTL) mapping approach was taken using a murine strain susceptible to paracetamol hepatotoxicity (C3H/HeH) crossed with a relatively resistant strain (C57BL/6). Novel QTLs on murine chromosome 17 and 18 were identified that associated with response to paracetamol. Within the loci a number of candidate genes were identified. A survey of 10 inbred mouse strains for their response to paracetamol was conducted and highlighted the large variability within each strain. It was hypothesised that this variability might be due to differences in intestinal microbiota. A study of the role of intestinal microbiota in paracetamol-induced liver failure was conducted, by comparing response in germ free (GF) mice and conventional (CV) controls. This demonstrated that the presence of intestinal microbiota influenced the sulphonation:glucuronidation ratio during paracetamol metabolism. Although the extent of liver injury as assessed by necrosis and liver enzyme elevation was the same in GF and CV mice, there was evidence of a protective effect of a sterile intestine. Finally a reverse genetics approach was taken to study the influence of the gene Slpi in the secondary immune response to liver injury. It was shown that absence of SLPI protected mice against peak liver injury. The work presented in this thesis highlights some potential sources of variability in response to paracetamol and a number of targets that with further research could have therapeutic potential.

Optimal control of differential inclusions
Creators: name: Palladino, Michele
Publisher: name: Imperial College London
Year: 2015

description: The thesis concerns some recent advances on necessary conditions for optimal control problems, paying particular attention to the case in which the velocity constraint is expressed in terms of a multifunction. In the first part of the thesis we have explored the link which arises between relaxation and first order necessary conditions. Relaxation is a widely used regularization procedure in optimal control, involving the replacement of velocity sets by their convex hulls, to ensure the existence of a minimizer. It turns out that some pathological situations arise in which the costs of relaxed and original problems do not coincide (infimum gap conditions). In this case, we cannot obtain approximate solution of the optimal control problem of interest. In particular, we show how necessary conditions expressed in terms of Fully Convexified Hamiltonian Inclusion are a↵ected by the presence of an infimum gap. Applications of these results are showed also in the case in which the velocity constraint is expressed in terms of controlled di↵erential equations. In the second part of the thesis we study the regularity of the Hamiltonian along the optimal trajectory for problems with state constraint. Two applications of these properties are demonstrated. One is to derive improved conditions which guarantee the nondegeneracy of necessary conditions of optimality, in the form of a Hamiltonian inclusion. The other application is to derive new, less restrictive, conditions under which minimizers in the calculus of variations have bounded slope.

description: Current unsupervised image-to-image translation techniques struggle to focus their attention on individual objects without altering the background or the way multiple objects interact within a scene. Motivated by the important role of attention in human perception, we tackle this limitation by introducing unsupervised attention mechanisms that are jointly adversarialy trained with the generators and discriminators. We demonstrate qualitatively and quantitatively that our approach is able to attend to relevant regions in the image without requiring supervision, and that by doing so it achieves more realistic mappings compared to recent approaches.
Optical Emission Lines from Warm Interstellar Clouds - a Decisive Test of the Decaying Neutrino Theory
Creators: name: Sciama, D. W.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Recently developed instruments such as the Taurus Tunable Filter and WHAM should be able to detect some or all of the optical emission lines H$α$, [OI] $λ$6300, [SII] $λ$6717, [NI] $λ$ 5200 and [NII] $λ$6584 from warm interstellar clouds such as those observed by Spitzer $&$ Fitzpatrick (1993) (SF) along the line of sight to the halo star HD93521. The strengths of these lines should resolve the debate as to whether the free electrons, which SF held responsible for the observed excitation of CII in the clouds, are located mainly in the skins of the clouds or in their interiors. If the free electrons are indeed mainly located in the cloud interiors, then the substantial electron density derived by SF, and its constancy from cloud to cloud for the slow-moving clouds, when combined with their opacity to Lyman continuum radiation, lend strong support to the decaying neutrino theory for the ionisation of the interstellar medium (Sciama 1990, 1993 a, b, 1997). If the [OI] and [NI] lines are relatively strong but the [NII] line is weak, then this would lend further, decisive, support to this theory, since decay photons are unable to ionise N, although its ionisation potential is only 0.9 eV greater than that of H.

description: The chromo magnetic dipole moment (CMDM) and chromo electric dipole moment (CEDM) of the top quark are calculated at the one-loop level in the framework of the two-Higgs doublet model with four fermion generations (4GTHDM), which is still consistent with experimental data and apart from new scalar bosons ($H^0$, $A^0$, and $H^\pm$) and quarks ($b'$ and $t'$) predicts new sources of $CP$ violation via the extended $4\times 4$ CKM matrix. Analytical expressions for the CMDM and CEDM of a quark are presented both in terms of Feynman parameter integrals and Passarino-Veltman scalar functions, with the main contributions arising from loops carrying the scalar bosons accompanied by the third- and fourth-generation quarks. The current bounds on the parameter space of the 4GTHDM are discussed and a region still consistent with the LHC data on the 125 GeV Higgs boson is identified. It is found that the top quark CMDM, which is induced by all the scalar bosons, can reach values of the order of $10^{-4}$-$10^{-3}$, with the dominant contributions arising from the fourth generation quarks, though may also be large cancellations for some parameter values, thereby giving a negligible CMDM. As for the top quark CEDM, it only receives contributions from the charged scalar boson and can reach values of the order of $10^{-19}$-$10^{-18}$ ecm for relatively light $m_{H^\pm}$ and large $m_{b'}$, with the dominant contribution arising from the $b'$ quark. The latter would be the most interesting prediction of this model as can be larger than the value predicted by the usual THDMs by one or two orders of magnitude.

description: Entropy production plays a fundamental role in nonequilibrium thermodynamics to quantify the irreversibility of open systems. Its positivity can be ensured for a wide class of setups, but the entropy production rate can become negative sometimes. This is often taken as an indicator of non-Markovian dynamics. We make this link precise by showing under which conditions a negative entropy production rate implies non-Markovian dynamics and when it does not. This is established within a unified language for two setups: (i) the dynamics resulting from a coarse-grained description of a system in contact with a single heat bath described by a Markovian master equation and (ii) the classical Hamiltonian dynamics of a driven system, which is coupled arbitrary strongly to a single heat bath. The quantum version of the latter result is shown not to hold despite the fact that the integrated thermodynamic description is formally equivalent to the classical case. The instantaneous steady state of a non-Markovian dynamics plays an important element in our study. Our key contribution is to provide a consistent theoretical framework to study the finite-time thermodynamics of a large class of dynamics with a precise link to its non-Markovianity.

A New Gauge/Gravity Dictionary via the Division Algebras
Creators: name: Nagy, Silvia
Publisher: name: Imperial College London
Year: 2015

description: The main goal of this thesis is to explore the idea of gravity as the square of a gauge theory at the level of Lagrangian symmetries. By regarding gravity as the convolution of left and right Yang-Mills theories together with a spectator scalar field in the bi-adjoint representation, we derive in linearised approximation the gravitational symmetries of general covariance, p-form gauge invariance, local Lorentz invariance and local supersymmetry from the at space Yang-Mills symmetries of local gauge invariance and global super-Poincare. As an example, we will we focus on the new-minimal (12 + 12) off-shell version of simple four-dimensional supergravity obtained by tensoring the off-shell Yang-Mills multiplets (4 + 4;N_L = 1) and (3 + 0;N_R = 0). By tensoring all possible pairs of on-shell super Yang-Mills multiplets in dimensions 3 ≤ D ≤ 10 to get on-shell supergravity multiplets, possibly with additional matter multiplets. By associating a (direct sum of) division algebra(s) D with each dimension 3 ≤ D ≤ 10 we obtain a formula for the supergravity U-duality G and its maximal compact subgroup H in terms of the internal global symmetry algebras of each super Yang-Mills theory. We then extend our analysis to include supergravities coupled to an arbitrary number of matter multiplets by allowing for non-supersymmetric multiplets in the tensor product. We also introduce the idea of writing the SYM multiplets themselves as a double copy. We construct the states and symmetries of N = 4 super-Yang-Mills by tensoring two N = 1 chiral multiplets and introducing two extra SUSY generators. This allows us to write the maximal N = 8 supergravity as four copies of the chiral multiplet. We extend this to higher dimensions and discuss possible applications.

THE ORBITAL ECCENTRICITIES OF BINARY MILLISECOND PULSARS IN GLOBULAR CLUSTERS

Publisher: name: arXiv
Year: 1995

description: Low-mass binary millisecond pulsars (LMBPs) are born with very small orbital eccentricities, typically of order $e_i\sim10^{-6}$--$10^{-3}$. In globular clusters, however, higher eccentricities $e_f\gg e_i$ can be induced by dynamical interactions with passing stars. Here we show that the cross section for this process is much larger than previously estimated. This is because, even for initially circular binaries, the induced eccentricity $e_f$ for an encounter with pericenter separation $r_{\rm p}$ beyond a few times the binary semi-major axis $a$ declines only as a power-law, $e_f\propto(r_{\rm p}/a)^ {-5/2}$, and {\it not\/} as an exponential. We find that {\it all\/} currently known \lmbps in clusters were probably affected by interactions, with their current eccentricities typically an order of magnitude or more greater than at birth.

description: Tidally-disrupted globular clusters are transformed into thin, dynamically-cold streams of stars that are extremely valuable tracers of the large- and small-scale distribution of mass in the Galaxy. Using data from the Gaia second data release combined with Pan-STARRS photometry, we present a sample of highly-probable members of the longest cold stream in the Milky Way, GD-1. The resulting map of GD-1: (1) extends the apparent length of the stream by $20^\circ$, (2) reveals plausible locations for the progenitor, (3) detects high-contrast gaps along the stream, and (4) indicates the existence of stream members perturbed off the main stream track. These discoveries are only possible because of the exquisite astrometry from Gaia, which permits a clean separation of the stream from Milky Way stars. The additional length and a proper treatment of the progenitor will aid in dynamical modeling of GD-1 for mapping the large-scale dark matter distribution. The complex morphology of the stream points to a turbulent history; detailed phase-space properties of the perturbed stream members could potentially constrain dark matter substructure in the Milky Way.

description: The discovery of X-ray, optical and radio afterglows of gamma-ray bursts (GRBs) and the measurements of the distances to some of them have established that these events come from Gpc distances and are the most powerful photon emitters known in the Universe, with peak luminosities up to 10^52 erg/s. We here report the discovery of an optical transient, in the BeppoSAX Wide Field Camera error box of GRB980425, which occurred within about a day of the gamma-ray burst. Its optical light curve, spectrum and location in a spiral arm of the galaxy ESO 184-G82, at a redshift z = 0.0085, show that the transient is a very luminous type Ic supernova, SN1998bw. The peculiar nature of SN1998bw is emphasized by its extraordinary radio properties which require that the radio emitter expand at relativistical speed. Since SN1998bw is very different from all previously observed afterglows of GRBs, our discovery raises the possibility that very different mechanisms may give rise to GRBs, which differ little in their gamma-ray properties.

Micro-structured hollow fibers for micro-tubular solid oxide fuel cells
Creators: name: Li, Tao
Publisher: name: Imperial College London
Year: 2015

description: Micro-tubular solid oxide fuel cells (MT-SOFCs) have received increasing research interest in the past decade. However, current development is restricted in R&D phase due to several technical challenges, such as expensive manufacturing route, which limits mass-scale production, and the difficulties in efficient current collection, especially from the small lumen of micro-tubes. In terms of fabrication, conventional routes usually consist of repetitions of coating and sintering, which is both time and cost-consuming. To tackle this problem, a phase inversion-assisted co-extrusion process has been established in this study, which dramatically simplifies the fabrication process, with improved adhesion. The phase inversion process could lead to the formation of an asymmetric structure, comprising micro-channels and a sponge-like structure. The former morphology could facilitate fuel transport, while the latter provides reactive sites for electrochemical reactions. The feasibility of the new manufacturing route has been established by fabricating anode/anode functional layer (AFL)/electrolyte triple-layer hollow fibers and the results suggest that inserting an AFL could effectively improve power density by 30% due to enlarged triple-phase boundary. As for the current collection from the lumen side, a new nickel-based current collector has been developed via co-extrusion. By controlling the fabrication parameters, a deliberate mesh-structure has been obtained with uniformly distributed entrances. Inserting this nickel-based inner layer considerably increases the electrical conductivity of anode and reduces gas diffusion resistance. After a complete cell was constructed, systematic electrochemical performance tests were undertaken. It has been illustrated that more uniform current collection has been achieved and contact loss, which is the major contributor towards ohmic loss in conventional current collectors, has been significantly reduced to less than 10% of total ohmic loss. This result indeed highlights the features of process economy and high efficiency of the new current collection design and suggests this design to be suitable for large-scale stack construction.

description: We report the results of new SPH calculations of parabolic collisions between main-sequence (MS) stars. The stars are assumed to be close to the MS turn-off point in a globular cluster and are therefore modeled as $n=3$, $Γ=5/3$ polytropes. We find that the high degree of central mass concentration in these stars has a profound effect on the hydrodynamics. In particular, very little hydrodynamic mixing occurs between the dense, helium-rich inner cores and the outer envelopes. As a result, and in contrast to what has been assumed in previous studies, blue stragglers formed by direct stellar collisions are not necessarily expected to have anomalously high helium abundances in their envelopes or to have their cores replenished with fresh hydrogen fuel.

description: Automatic detection and segmentation of cells and nuclei in microscopy images is important for many biological applications. Recent successful learning-based approaches include per-pixel cell segmentation with subsequent pixel grouping, or localization of bounding boxes with subsequent shape refinement. In situations of crowded cells, these can be prone to segmentation errors, such as falsely merging bordering cells or suppressing valid cell instances due to the poor approximation with bounding boxes. To overcome these issues, we propose to localize cell nuclei via star-convex polygons, which are a much better shape representation as compared to bounding boxes and thus do not need shape refinement. To that end, we train a convolutional neural network that predicts for every pixel a polygon for the cell instance at that position. We demonstrate the merits of our approach on two synthetic datasets and one challenging dataset of diverse fluorescence microscopy images.

description: We discuss the feasibility of finding extra-galactic MACHOs by monitoring quasars behind the Virgo cluster of galaxies. We show that with only a modest observing programme one could detect several MACHOs in the mass range 1 X 10^{-5} to 2 X 10^{-2} solar masses if they make a significant contribution to the mass of Virgo. The contamination by events from cosmologically distributed MACHOs is estimated and is negligible if either the MACHO mass is greater than about 10^{-4} solar masses or the quasar radius is greater than about 3 X 10^{15} cm.

description: Periodically patterned metamaterials are known for exhibiting wave properties similar to the ones observed in electronic band structures in crystal lattices. In particular, periodic ferromagnetic materials are characterized by the presence of bands and bandgaps in their spin-wave spectrum at tunable GHz frequencies. Recently, the fabrication of magnets hosting Dzyaloshinskii-Moriya interactions has been pursued with high interest since properties such as the stabilization of chiral spin textures and nonreciprocal spin-wave propagation emerge from this antisymmetric exchange coupling. In this context, to further engineer the magnon band structure, we propose the implementation of magnonic crystals with periodic Dzyaloshinskii-Moriya interactions, which can be obtained, for instance, via patterning of periodic arrays of heavy-metals wires on top of an ultrathin magnetic film. We demonstrate through theoretical calculations and micromagnetic simulations that such systems show an unusual evolution of the standing spin waves around the gaps in areas of the film that are in contact with the heavy-metal wires. We also predict the emergence of indirect gaps and flat bands and, effects that depend on the strength of the Dzyaloshinskii-Moriya interaction. This study opens new routes towards engineered metamaterials for spin-wave-based devices.

description: We investigate the time evolution of an open quantum system described by a Lindblad master equation with dissipation acting only on a part of the degrees of freedom ${\cal H}_0$ of the system, and targeting a unique dark state in ${\cal H}_0$. We show that, in the Zeno limit of large dissipation, the density matrix of the system traced over the dissipative subspace ${\cal H}_0$, evolves according to another Lindblad dynamics, with renormalized effective Hamiltonian and weak effective dissipation. This behavior is explicitly checked in the case of Heisenberg spin chains with one or both boundary spins strongly coupled to a magnetic reservoir. Moreover, the populations of the eigenstates of the renormalized effective Hamiltonian evolve in time according to a classical Markov dynamics. As a direct application of this result, we propose a computationally-efficient exact method to evaluate the nonequilibrium steady state of a general system in the limit of strong dissipation.

Diffusion of CO2 in fluids relevant to carbon capture, utilisation and storage
Creators: name: Cadogan, Shane
Publisher: name: Imperial College London
Year: 2015

description: In this work, molecular diffusion coefficients of carbon dioxide (CO2) in liquids relevant to carbon capture, utilisation and sequestration and enhanced oil recovery are reported. These parameters are necessary for the accurate and optimal design and control of such processes. Knowledge of these values is required to fully describe the migration of CO2 away from the injection wells and also for calculating the rate of absorption of CO2 into the formation fluids. However, diffusion coefficients are amongst the least studied of thermophysical properties, especially at high pressure, high temperature conditions. This work extended previous measurements where available, and produced new measurements where not, of diffusion coefficients at infinite dilution of CO2 in H2O, and several relevant brines and hydrocarbons at high temperatures (< 423 K) and high pressures (< 69 MPa). The Taylor dispersion method was used to determine diffusion coefficients for CO2 in water and selected hydrocarbons. The hydrocarbons chosen as representative of major crude oil components were n-heptane, nhexadecane, squalane, cyclohexane, and toluene. A technique based on nuclear magnetic resonance was used to measure effective diffusion coefficients of CO2 in several brines, encompassing monovalent and divalent salts, and a mixed brine. The diffusion coefficients of CO2 in water were correlated using the Stokes-Einstein equation in which the Stokes-Einstein number was assigned a value of 4 and the hydrodynamic radius was treated as a linear function of temperature. No relationship between brine salinity and the hydrodynamic radius was found. The results indicated pressure did not have an observable impact on the diffusivity in aqueous systems. The experimental uncertainty was found to be 2.3% with a coverage factor of 2 for the CO2-water system and 1.5% with a coverage factor of 2 for the CO2-brine systems. In contrast to aqueous systems, the diffusion coefficient of CO2 in hydrocarbons was found to be strongly dependent on pressure. At a given temperature the diffusion coefficient decreased by up to 50% over the pressure range investigated (1 to 69 MPa). A correlation based on the Stokes-Einstein equation and a two-parameter correlation based on the rough hard sphere theory was used to model the experimental results. The experimental uncertainty was found to be 1.5% with a coverage factor of 2.

description: We train Artificial Neural Networks to classify galaxies based solely on the morphology of the galaxy images as they appear on blue survey plates. The images are reduced and morphological features such as bulge size and the number of arms are extracted, all in a fully automated manner. The galaxy sample was first classified by 6 independent experts. We use several definitions for the mean type of each galaxy, based on those classifications. We then train and test the network on these features. We find that the rms error of the network classifications, as compared with the mean types of the expert classifications, is 1.8 Revised Hubble Types. This is comparable to the overall rms dispersion between the experts. This result is robust and almost completely independent of the network architecture used.

description: Exact fractals of nonlinear waves that rely on strong dispersion and nonlinearity and arise spontaneously out of magnetic media were observed for the first time. The experiments make use of a microwave to excite a spin wave in a quasi-one-dimensional magnonic crystal. When the power of the input microwave (Pin) is low, the output signal has a power-frequency spectrum that consists of a single peak. When Pin is increased to a certain level, the new side modes are generated through modulational instability (MI), resulting in a comb-like frequency spectrum. With a further increase in Pin, each peak in the frequency comb can evolve into its own, finer comb through the MI. As Pin is increased further, one can observe yet another set of finer frequency combs. Such a frequency-domain fractal manifests itself as multiple layers of amplitude modulation in the time-domain signal.
