Line Emission from an Accretion Disk around a Black hole: Effects of Disk Structure

description: The observed iron K-alpha fluorescence lines in Seyfert-1 galaxies provide strong evidence for an accretion disk near a supermassive black hole as a source of the line emission. These lines serve as powerful probes for examining the structure of inner regions of accretion disks. Previous studies of line emission have considered geometrically thin disks only, where the gas moves along geodesics in the equatorial plane of a black hole. Here we extend this work to consider effects on line profiles from finite disk thickness, radial accretion flow and turbulence. We adopt the Novikov and Thorne (1973) solution, and find that within this framework, turbulent broadening is the dominant new effect. The most prominent change in the skewed, double-horned line profiles is a substantial reduction in the maximum flux at both red and blue peaks. The effect is most pronounced when the inclination angle is large, and when the accretion rate is high. Thus, the effects discussed here may be important for future detailed modeling of high quality observational data.

description: Distortions of the Cosmic Microwave Background energy spectrum of the $μ$ type are sensitive to the primordial power spectrum through the dissipation of curvature perturbations on scales $k\simeq 50$ - $10^4\,\mathrm{Mpc}^{-1}$. Their angular correlation with large-scale temperature anisotropies is then sensitive to the squeezed limit of the primordial bispectrum. For inflationary models obeying the single-field consistency relation, we show that the observed $μT$ angular correlation that would correspond to the local shape vanishes exactly. All leading non-primordial contributions, including all non-linear production and projection effects, are of the "equilateral shape", namely suppressed by $k^2/{\cal H}_f^2$, where ${\cal H}_f\simeq 10^{-1}\,{\rm Mpc}^{-1}$ is the Hubble radius at the end of the $μ$-era. Therefore, these non-primordial contributions are orthogonal to a potential local primordial signal (e.g. from multi-field inflation). Moreover, they are very small in amplitude. Our results strengthen the position of $μ$ distortions as the ultimate probe of local primordial non-Gaussianity.

description: A statistical analysis of texture on the {\it COBE}-DMR first year sky maps based on the genus and spot number is presented. A generalized $χ^2$ statistic is defined in terms of ``observable'' quantities: the genus and spot density that would be measured by different cosmic observers. This strategy together with the use of Monte Carlo simulations of the temperature fluctuations, including all the relevant experimental parameters, represent the main difference with previous analyses. Based on the genus analysis we find a strong anticorrelation between the quadrupole amplitude $Q_{rms-PS}$ and the spectral index $n$ of the density fluctuation power spectrum at recombination of the form $Q_{rms-PS}= 22.2 \pm 1.7 - (4.7 \pm 1.3) \times n\ μ$K for fixed $n$, consistent with previous works. The result obtained based on the spot density is consistent with this $Q_{rms-PS} (n)$ relation. In addition to the previous results we have determined, using Monte Carlo simulations, the minimum uncertainty due to cosmic variance for the determination of the spectral index with the genus analysis. This uncertainty is $δn\approx 0.2$.

Generic Evolution Of Deuterium And Helium-3

description: The primordial abundances of deuterium and of helium-3, produced during big bang nucleosynthesis, depend sensitively on the baryon density. Thus, the observed abundances of D and \he may provide useful ``baryometers'' provided the evolution from primordial to present (or, presolar nebula) abundances is understood. Inevitably, the derivation of primordial from observed abundances requires the intervention of a model for galactic evolution and, so, the inferred primordial abundances are, necessarily, model dependent. Here, an analytic framework for the evolution of D and \he is presented which is ``generic'' in the sense that it should describe the results of any specific galactic evolution model. The ``effective \he survival fraction'', $Γ_3$, is the one free parameter which is model specific. Solar system and interstellar data are used to infer upper and lower bounds to the primordial deuterium mass fraction $(X_{2P})$ as a function of $Γ_3$ and, these bounds are used to constrain the present baryon-to-photon ratio $(η)$ and baryon density $(Ω_B)$. For $Γ_3 \geq$ 1/4 it is found that (from D and \he alone): $3.1 \leq η_{10} \leq 9.0$; $0.045 \leq Ω_B h^2_{50} \leq 0.133$ (where $H_0 = 50h_{50}$ km$\,$s$^{-1}$ Mpc$^{-1}$).

description: Fermion dynamics distinguishes spacetimes having the same metric $g_{μν}$, but different tetrads $e_{μa}$, and in particular, it distinguishes a lapse with negative sign, $N<0$.[1] Here we show that the quasiequilibrium thermodynamic state may exist, in which the region with $N<0$ has negative local temperature $T({\bf r})<0$, while the global Tolman temperature $T_0$ remains positive. For bosons, only $N^2$ matters. However, if bosons are composite, they may inherit the negative $T({\bf r})$ from the fermions, and thus they may distinguish the spacetimes with positive and negative lapse functions via thermodynamics.

description: We consider normal-superconductor (NS) and superconductor-normal-superconductor (SNS) junctions based on one-dimensional nanowires with Rashba spin-orbit coupling and proximity-induced $s$-wave spin-singlet superconductivity and analytically demonstrate how both even- and odd-frequency and spin-singlet and -triplet superconducting pair correlations are always present. In particular, by using a fully quantum mechanical scattering approach, we show that Andreev reflection induces mixing of spatial parities at interfaces, thus being the unique process which generates odd-frequency pairing; on the other hand, both Andreev and normal reflections contribute to even-frequency pairing. We further find that locally neither odd-frequency nor spin-triplet correlations are induced, but only even-frequency spin-singlet pairing. In the superconducting regions of NS junctions, the interface-induced amplitudes decay into the bulk, with the odd-frequency components being generally much larger than the even-frequency components at low frequencies. The odd-frequency pairing also develops short and long-period oscillations due to the chemical potential and spin-orbit coupling, respectively, leading to a visible beating feature in their magnitudes. Moreover, we find that in short SNS junctions at $π$-phase difference and strong spin-orbit coupling, the odd-frequency spin-singlet and -triplet correlations strongly dominate with an alternating spatial pattern for a large range of sub-gap frequencies.

Spectral classification and HR diagram for symbiotic stars in the galactic bulge

description: A sample of 45 symbiotic stars observed in the direction of the galactic bulge are classified in spectral type using TiO $λλ6180, 7100 Å$ and VO $λλ7865 Å$ absorption feature indices and visual comparison. The effective temperatures obtained are used together with K data from the literature to estimate the bolometric luminosity of the giant components if located at d=8.5 kpc. The ($T_{eff}$, $L/L_{\odot}$) pairs are plotted on the HR diagram together with evolutionary tracks for metal rich intermediate mass stars. The mass of the giant components seem to be scattered in the interval ($\sim 1.5 - \sim 4 M_{\odot}$). The giant components of D-type symbiotics appear as if they were more evolved objects than the corresponding giants in S-type systems. Nevertheless, it is unlikely that they form an evolutionary sequence. The results point also to the restriction of the symbiotic phenomenon to the thermally pulsating phase of the AGB, strengthening an accelerated mass loss scenario for the latest evolutionary stages of intermediate mass stars.

description: The bioavailability and potential uptake of heavy metals by crops is fundamentally influenced by the forms of metals in soils. Organic matter plays an important role in controlling the transformation of heavy metal fractionations in soils. However, long-term effects of organic matter on heavy metal speciation remains highly uncertain. In this study, rice straw was introduced to a subtropical Pb-contaminated soil for 2-year period so as to clarify the redistribution of Pb fractions and their correlations with soil properties. By combining sequential extraction and X-ray absorption fine structure spectroscopy, we find that lead is predominantly presented in Fe oxide-bound, surface adsorbed, and residual fractions in the soil. The incorporation of rice straw can effectively reduce the labile species of Pb by promoting the binding of Pb to iron oxides. Furthermore, aging leads to the transfer of considerable amounts of Pb to the association with Fe oxides and this transformation is enhanced by the presence of organic matter. Organic matter input and soil aging tend to shift Pb to amorphous Fe oxides than crystalline Fe oxides. The correlation analysis shows that Fe oxide fractions play vital roles in controlling the forms of Pb in soil. This study presents the first result regarding the long-term effect of organic matter on the redistribution of Pb in naturally polluted soil, which is useful for understanding the fate of Pb and developing remediation strategies for Pb-polluted soils.

description: We carry out a detailed orbit analysis of gravitational potentials selected at different times from an evolving self-consistent model galaxy consisting of a two-component disk (stars+gas) and a live halo. The results are compared with a pure stellar model, subject to nearly identical initial conditions, which are chosen as to make the models develop a large scale stellar bar. The bars are also subject to hose-pipe (buckling) instability which modifies the vertical structure of the disk. The diverging morphological evolution of both models is explained in terms of gas radial inflow, the resulting change in the gravitational potential at smaller radii, and the subsequent modification of the main families of orbits, both in and out of the disk plane. We find that dynamical instabilities become milder in the presence of the gas component, and that the stability of planar and 3D stellar orbits is strongly affected by the related changes in the potential -- both are destabilized with the gas accumulation at the center. This is reflected in the overall lower amplitude of the bar mode and in the substantial weakening of the bar, which appears to be a gradual process. The vertical buckling of the bar is much less pronounced and the characteristic peanut shape of the galactic bulge almost disappears when there is a substantial gas inflow towards the center. Milder instability results in a smaller bulge whose basic parameters are in agreement with observations. We also find that the overall evolution in the model with a gas component is accelerated due to the larger central mass concentration and resulting decrease in the characteristic dynamical time.

description: Helium films show various quantum phases that undergo quantum phase transitions by changing coverage n. We found anomalous elastic phenomena in bosonic 4He and fermionic 3He films adsorbed on a glass substrate. The films stiffen under AC strain at low temperature with an excess dissipation. The onset temperature of the stiffening decreases to 0 K as n approaches a critical coverage nc. The elastic anomaly is explained by thermal activation of helium atoms from the localized to extended states with a distributed energy gap. We determine for the first time the energy band structure of helium films from elasticity. The ground states of 4He and 3He at n < n_c are identically gapped and compressible, which are possibly a sort of Mott insulator or Mott glass.

The pattern speed of the bar in NGC 936
Creators: name: Merrifield, Michael R.
name: Kuijken, Konrad
Publisher: name: arXiv
Year: 1995
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We have used the Tremaine-Weinberg method to measure the angular speed of rotation for the bar in the SB0 galaxy NGC 936. With this technique, the bar's pattern speed, Omega_p, can be derived from the luminosity and stellar-kinematic information in long-slit spectral observations taken parallel to the major axis of the galaxy. The kinematic measurement required is the mean line-of-sight velocity of all stellar light entering the slit. This quantity can only be calculated reliably if any asymmetry in the shape of the broadening function of the spectral lines is also measured, and so we present a method which allows for such asymmetry. The technique also returns a true measure of the RMS uncertainty in the estimate. Application of the analysis to a set of long-slit spectra of NGC 936 returns four separate measures of Omega_p which are mutually consistent. Combining these data produces a best estimate for the bar pattern speed of Omega_p = 60 +/- 14 km/s/kpc (assuming a distance of 16.6 Mpc). This result refines the only previous attempt to make this measurement, which yielded an estimate for Omega_p in NGC 936 of 104 +/- 37 km/s/kpc (Kent 1987). The new measurement places the co-rotation radius just beyond the end of the bar, in agreement with theoretical calculations.

Model-based Aeroservoelastic Design and Load Alleviation of Large Wind Turbines
Creators: name: Ng, Bing Feng
Publisher: name: Imperial College London
Year: 2014

description: With the increase in size of wind turbine for larger energy capture, aeroelastic effects previously not seen in smaller rotors are beginning to surface as a result of increased blade flexibility. This has brought about new needs in terms of modelling requirements and methods of load control to improve the fatigue life of turbine blades. This dissertation presents an aeroservoelastic modelling approach for dynamic load alleviation in large wind turbines with trailing-edge aerodynamic surfaces. Time-domain aerodynamics are given by a linearised three-dimensional unsteady vortex-lattice method that allows better characterisation of aeroelastic responses under attached flow conditions and the direct modelling of lifting surfaces. The resulting unsteady aerodynamics is written in a state-space formulation suitable for model reductions and controller design. This approach does not rely on empirical corrections commonly found in Blade Element Momentum methods. Structural modules of the tower, potentially on a moving base, and the rotating blades are modelled using geometrically non-linear composite beams, which are linearised around reference conditions that have undergone arbitrarily-large structural displacements. The land-based NREL 5MW reference wind turbine is chosen to demonstrate the unified aeroelastic framework, in which the coupled rotor and tower description is modelled to examine both the aeroelastic effects and potential of load alleviation. In the presence of realistic wind fields, turbine blade root-bending moments and tower deflections can be reduced by 13% using active control methods. When combined with passive mechanisms through bend-twist coupling, performance can be improved to more than 40%. The baseline configuration is further extended to cover offshore floating wind turbine concepts. The focus of this dissertation is to provide higher-fidelity efficient numerical models for linear robust controller design (LQG and Hinf), to achieve load alleviation in larger and more flexible wind turbines.

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.

Pricing Inflation and Interest Rates Derivatives with Macroeconomic Foundations
Creators: name: Sarais, Gabriele
Publisher: name: Imperial College London
Year: 2015

description: I develop a model to price inflation and interest rates derivatives using continuous-time dynamics linked to monetary macroeconomic models: in this approach the reaction function of the central bank, the bond market liquidity, and expectations play an important role. The model explains the effects of non-standard monetary policies (like quantitative easing or its tapering) on derivatives pricing. A first adaptation of the discrete-time macroeconomic DSGE model is proposed, and some changes are made to use it for pricing: this is respectful of the original model, but it soon becomes clear that moving to continuous time brings significant benefits. The continuous-time model is built with no-arbitrage assumptions and economic hypotheses that are inspired by the DSGE model. Interestingly, in the proposed model the short rates dynamics follow a time-varying Hull-White model, which simplifies the calibration. This result is significant from a theoretical perspective as it links the new theory proposed to a well-established model. Further, I obtain closed forms for zero-coupon and year-on-year inflation payoffs. The calibration process is fully separable, which means that it is carried out in many simple steps that do not require intensive computation. The advantages of this approach become apparent when doing risk analysis on inflation derivatives: because the model explicitly takes into account economic variables, a trader can assess the impact of a change in central bank policy on a complex book of fixed income instruments, which is not straightforward when using standard models. The analytical tractability of the model makes it a candidate to tackle more complex problems, like inflation skew and counterparty/funding valuation adjustments (known by practitioners as XVA): both problems are interesting from a theoretical and an applied point of view, and, given their computational complexity, benefit from a tractable model. In both cases the results are promising.

description: While most aspects of the Regional Assistance Mission to Solomon Islands (RAMSI) have been well documented, less has been said about the significant contribution of the Pacific Island police who served with it. Pacific Islanders undertook important civilian roles, but the largest numbers were deployed to RAMSI’s Participating Police Force (PPF). Although the bulk of the PPF were from Australia and New Zealand, approximately one-fifth were Pacific Island police — referred to as the Pacific Island contingent (PI contingent) — from 13 countries: Cook Islands, Federated States of Micronesia, Fiji, Kiribati, Marshall Islands, Nauru, Niue, Palau, Papua New Guinea, Samoa, Tonga, Tuvalu, and Vanuatu. Their contribution underscored the mission’s regional nature and sustained support for RAMSI. Drawing on more than 100 interviews, this In Brief summarises preliminary findings from a research project supported by the Australian Federal Police (AFP) that has been examining the experience and impact of RAMSI’s PI contingent on its individual participants, their home police organisations, and on regional policing more broadly.
Circuits and systems for DNA detection by ion-sensitive field effect transistor
Creators: name: Sohbati, Mohammadreza
Publisher: name: Imperial College London
Year: 2014

description: This thesis, after a review on the state-of-the-art sequencing and genotyping technologies, focuses on the semiconductor-based systems using pH change for DNA (Deoxyribonucleic acid) detection by ion-sensitive feld effect transistors (ISFETs). Accuracy and throughput, besides cost, are the key concerns in these systems, which are reflected on their signal-to-noise ratio and ability to process enormous measurement data at low levels for base-calling. Simulations are provided on the signal behaviour, supported by the literature review. The ISFETs have been investigated for their dimension and shape (single-plate vs mesh, and square vs octagonal). More complete formula and design methodology (to suppress the process variations and signal drift) have been provided for the ISFET operation by including the coupling effect. The experiment results, on 8 dies each containing 15 devices, showed the decoupling parasitics dependency on the sensing area perimeter. A buffer-shield structure has been proposed to improve the ISFET coupling. In addition, based on the ISFET drift analysis, measuring the biasing reference electrode current is recommended for the drift direction monitoring/prediction. Considering the two main applications of sequencing and genotyping, new readout configurations have been proposed to enhance the on-chip signal processing. Piecewise linear approximating (PLA), and temperature-insensitive continuous-time ΔpH to digital converter (TICTC), tackle the ISFET and temperature dependency. The TICTC has been designed for a resolution of 0.015pH, easily scalable and only dependent on the relative aspect ratio of its current mirrors. Its dynamic range is not limited despite operating in weak inversion. For very large-scale sequencing arrays, common-mode noise elimination using the back-gate has been proposed. It allows on-chip suppression of the background noise in the sequencing microchips, reducing the low-level processing load. Moreover, a pseudo-inverter-based readout has been designed that may allow improving the conversion resolution by current-mode comparison and indirect feedback to the ISFET gate.
The effect of implant misalignment on shoulder replacement outcomes
Creators: name: Sukjamsri, Chamaiporn
Publisher: name: Imperial College London
Year: 2015

description: Total shoulder arthroplasty is a well-established treatment to relieve pain and restore joint function particularly in arthritis patients. The damaged shoulder joint is replaced with humeral and glenoid components. For success, all replacement components must be aligned properly. However, errors in glenoid component alignment particularly in version is not infrequent due to the complexities such as limited monitoring available during the surgical procedure and glenoid posterior wear, commonly observed in glenohumeral osteoarthritis. Glenoid component version has been found to induce eccentric load and may result in component loosening which is the main indicator for revision surgery. The overall aim of this thesis is to gain the in-depth understanding of how the component version affects the fixation loosening in both cementless and cemented shoulder arthroplasty. Early loosening in cementless arthroplasty is associated with failed biological fixation due to excessive micromotion at the implant-bone interface. To measure interface micromotion, this thesis developed an in-vitro technique based on the application of digital volume correlation (DVC) and micro-computed tomography (μCT). This technique was validated and verified the use of the finite element (FE) method as a tool for investigating the effect of glenoid component version on micromotion. The FE predicted micromotion during a full range of shoulder abduction confirmed that 60° of abduction was the critical position inducting the largest micromotion and large micromotions were shown to be related to increased component retroversion. The condition of the bone was also found to be an important parameter as less stiff bone caused large micromotions.
Mechanobiological predictions of fetal joint morphogenesis
Creators: name: Giorgi, Mario
Publisher: name: Imperial College London
Year: 2015

description: This PhD thesis explores, through the use of a mechanobiological simulation of prenatal joint morphogenesis, the hypotheses on how fetal movements, shapes and position impact on the shape of the developing joint. A novel mechanoregulation algorithm specific for cartilage growth was developed and, for the first time, a 3D mechanobiological simulation of joint morphogenesis in which the effects of a range of movements and different initial joint shapes was proposed. Both pre- and post-cavitational phases of joint development were simulated and the effect of rigid paralysis on joint shape was also explored. This study concluded that the starting joint configuration and applied movement are fundamental for the development of specific and anatomically recognisable joint shapes. Moreover, for the first time, a mechanobiological simulation of prenatal hip joint morphogenesis was used to investigated the effects of reduced, or asymmetric, movement at various stages of fetal hip joint development. This study concluded that normal fetal movements are important for the emergence of a physiological hip joint shape and that movements during development tend to minimise the natural trend of decreasing stability. Results showed that reduced movements at an early stage of development lead to decreased sphericity and acetabular coverage of the femoral head, increasing the risk of subluxation or dislocation of the hip. It also shows that, in the case of mal-positioning or joint laxity in utero, movements may actually lead to an abnormal hip joint shape with characteristics of developmental dysplasia of the hip (DDH). This PhD thesis has advanced the basic understanding of prenatal joint shape development and the implication that different mechanical environments within the joint region, might have on developmental skeletal diseases such as DDH.

description: We investigate the statistical properties of primordial black hole (PBH) formation in the very early Universe. We show that the high level of inhomogeneity of the early Universe leads to the formation of the first generation PBHs. %The existence of these PBHs This causes later the appearance of a dust-like phase of the cosmological expansion. We discuss here a new mechanism for the second generation of PBH formation during the dust-like phase. This mechanism is based on the coagulation process. We demonstrate that the blue power spectrum of initial adiabatic perturbations after inflation leads to overproduction of primordial black holes with $10^9$g$\le M\le10^{15}$g if the power index is $n\ge1.2$.

description: A series of liquid crystals (LCs) of bromine-terminated azobenzene were synthesised and characterised. The LCs were composed of an azobenzene core, an alkyl chain and a flexible spacer with a bromine atom at a remote position. Mesomorphic properties were dependent on both the alkyl chain length and the relative position of the bromine atom at the end of the spacer group. The nematic phase was favoured over the smectic A phase for alkyl chains with one and seven carbon atoms. However, the SmA mesophase was dominant for compounds with 10-carbon alkyl chains. The remote bromine atom in the spacer group favoured SmA for homologous with n-decyl chains and the nematic phase for n-heptyl and methyl groups. Molecular modelling showed that the azobenzene LCs tended to adopt the all trans-conformation in the gas phase as the number of carbon atoms increased. For short spacer groups, bent conformations contributed to the level population proportion of conformers. For the non-LC 5a, the gauche conformation became the most stable with a torsional angle of –68.9°. X-ray experiments showed a monolamellar SmA mesophase in an antiparallel arrangement. Absorption maxima at 360 and 440 nm were assigned to π–π* and n–π* transitions, respectively.
