Why Not Consider Closed Universes?

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: We consider structure formation and CMB anisotropies in a closed universe, both with and without a cosmological constant. The CMB angular power spectrum and the matter transfer function are presented, along with a discussion of their relative normalization. This represents the first full numerical evolution of density perturbations and anisotropies in a spherical geometry. We extend the likelihood function vs. Omega from the COBE 2-year data to Omega>=1. For large Omega the presence of a very steep rise in the spectrum towards low ell allows us to put an upper limit of Omega<=1.5 (95%CL) for primordial spectra with n<=1. This compares favorably with existing limits on Omega. We show that there are a range of closed models which are consistent with observational constraints while being even older than the currently popular flat models with a cosmological constant. Future constraints from degree scale CMB data may soon probe this region of parameter space. A derivation of the perturbed Einstein, fluid and Boltzmann equations for open and closed geometries is presented in an appendix.

description: We present our analysis of archival Hubble Space Telescope Wide Field Planetary Camera 2 (WFPC2) observations in F450W (~B) and F555W (~V) of the intermediate- age populous star clusters NGC 121, NGC 339, NGC 361, NGC 416, and Kron 3 in the Small Magellanic Cloud. We use published photometry of two other SMC populous star clusters, Lindsay 1 and Lindsay 113, to investigate the age sequence of these seven populous star clusters in order to improve our understanding of the formation chronology of the SMC. We analyzed the V vs (B-V) and M_V vs (B-V)_0 color-magnitude diagrams of these populous Small Magellanic Cloud star clusters using a variety of techniques and determined their ages, metallicities, and reddenings. These new data enable us to improve the age-metallicity relation of star clusters in the Small Magellanic Cloud. In particular, we find that a closed-box continuous star-formation model does not reproduce the age-metallicity relation adequately. However, a theoretical model punctuated by bursts of star formation is in better agreement with the observational data presented herein.

The transport and deposition of molybdenum in porphyry ore systems
Creators: name: Spencer, Edward
Publisher: name: Imperial College London
Year: 2015

description: Approximately 99% of Mo is obtained from porphyry deposits (e.g. Sillitoe, 2010), representing the strongest association of any metal with a single deposit type. Despite this, the controls on the formation of Mo-rich porphyries and the spatial-temporal decoupling of Mo from Cu in these systems remain poorly understood. By combining fieldwork, Re-Os molybdenite dating and a fluid inclusion study at one of the world’s largest Cu-Mo porphyries (El Teniente, Chile), this project assesses the magmatic-hydrothermal evolution of the system to help constrain the processes controlling Mo enrichment. Results indicate that deposit-wide Mo grades of <0.06 wt.% are principally controlled by the abundance of main mineralisation-type quartz-molybdenite veins, that develop outwards and upwards into Cu-rich vein types. Parental ore fluids had low salinities (~6.5 wt.% NaCleq) and were exsolved at depth following the emplacement of multiple intrusions that acted as short-lived (<100,000 years) conduits for mineralising fluids between 6.3 and 4.6 Ma. The decoupled deposition of Mo and Cu surrounding each temporally separate intrusion is attributed to the sequential deposition of Mo then Cu in response to decreasing temperature followed by intermittent fluid boiling and increasing fluid pH in response to sericitic alteration of the mafic host-rocks. Mo grades >0.06 wt.% correspond to the presence of late mineralisation-type veins and breccias produced by the exsolution of Mo-rich brines ±aqueous fluids from a highly fractionated magma source. Mineralisation in this stage was short-lived and occurred in all parts of the deposit at ~4.6 Ma. The relatively Cu-poor nature of this stage is attributed to the prior preferential extraction of Cu from the underlying magma chamber in earlier mineralising events. In accordance with data from other Mo-rich porphyry systems, results indicate that Mo-Cu decoupling is controlled by both changes in magma chemistry as well as by the evolving P-T-X properties of hydrothermal fluids.

description: We evaluate the significance of the line candidates identified by a visual search of burst spectra from BATSE's Spectroscopy Detectors. None of the candidates satisfy our detection criteria: an F-test probability less than 10^-4 for a feature in one detector and consistency among the detectors which viewed the burst. Most of the candidates are not very significant, and are likely to be fluctuations. Because of the expectation of finding absorption lines, the search was biased towards absorption features. We do not have a quantitative measure of the completeness of the search which would enable a comparison with previous missions. Therefore a more objective computerized search has begun.

description: For many years broadband colours have been used to obtain insight into the contents of galaxies, in particular to estimate stellar and dust content. Broadband colours are easy to obtain for large samples of objects, making them ideal for statistical studies. In this paper I use the radial distribution of the colours in galaxies, which gives more insight into the local processes driving the global colour differences than integrated colours. Almost all galaxies in my sample of 86 face-on galaxies become systematically bluer with increasing radius. The radial photometry is compared to new dust extinction models and stellar population synthesis models. This comparison shows that the colour gradients in face-on galaxies are best explained by age and metallicity gradients in the stellar populations and that dust reddening plays a minor role. The colour gradients imply $M/L$ gradients, making the `missing light' problem as derived from rotation curve fitting even worse.

The photometry was carried out using a filter set identical to that which will be used for the Sloan Digital Sky Survey. We find that carbon stars, CVs, R-type, J-type, and V-type asteroids, BHB stars, and RR Lyr stars should be identifiable on the basis of SDSS photometry alone, while Cepheids, metal-poor stars, and many types of asteroids are indistinguishable from the stellar locus of field stars.

Estimating the permeability of reservoir sandstones using image analysis of pore structure
Creators: name: Lock, Peter
Publisher: name: Imperial College London
Year: 2001

description: In this thesis, a method is developed for predicting the permeabilities of a core using only a small number of SEM images, without resorting to computationally intensive procedures. The pore structure is idealised as consisting of a cubic network of pore tubes having an arbitrary distribution of cross-sectional areas and shapes. The areas and perimeters of the individual pores are estimated from image analysis of scanning electron micrographs of thin sections, with appropriate stereological corrections introduced to infer the true cross sections of the pores. Effective medium theory is used to find the effective single-tube conductance, based on the measured distribution of individual conductances, thereby allowing a prediction of the permeability. The methodology has been applied to several reservoir sandstones from the North Sea, and also an outcrop sample from Cumbria, UK, yielding predictions that fall within a factor of two of the laboratory measurements in most cases. The procedure, although based on Kirkpatrick's intrinsically isotropic effectivemedium approximation, is not only capable of yielding reasonably accurate estimates of the permeabilities, but also gives a qualitatively correct indication of the anisotropy ratio. It also found that the use of an Bernasconi's anisotropic effective-medium approximation does not lead to a systematic improvement in the results, perhaps because the samples used in this study were insufficiently anisotropic for the approaches to yield different results. The validity of the effective medium approximation was also tested against exact pore network calculations. For the rocks examined in this study, with pore conductance distributions having log-variances less than 3, the effective medium approximation was found to be accurate to within a few percent.

description: The practice, theory, and critique of allyship have been central to feminist scholarship and activism. Identities once not regarded as identities at all but as neutral givens, such as maleness, whiteness, cisnormativity, heterosexuality, abledness, and settlerhood, have all become politicized planes of analysis and action. Yet little scholarship, praxis, and activism has held people with thin privilege accountable for the role they play in fueling the fires of fatphobia in the day to day. Even while fat studies and fat activisms have worked to dismantle fatphobia, thin people have rarely been asked to play pivotal roles in dismantling fatphobic worldviews. In this piece, we draw on anti-racist feminism, disability studies, and fat activism to think about what it might take to become a fat ally. Grounded in our collaborative corporeality as a (very) fat and (very) thin person, we hone the method of research-practice in this part theoretical essay and part action zine. Specifically, we argue that for fat allyhood to be possible, allies need to hone anti- rather than non-fatphobic commitments and practices grounded in what Mia Mingus frames as “access intimacy.”

description: This work presents an optimally-competitive algorithm for the problem of maximum weighted online perfect bipartite matching with i.i.d. arrivals. In this problem, we are given a known set of workers, a distribution over job types, and non-negative utility weights for each pair of worker and job types. At each time step, a job is drawn i.i.d. from the distribution over job types. Upon arrival, the job must be irrevocably assigned to a worker and cannot be dropped. The goal is to maximize the expected sum of utilities after all jobs are assigned. We introduce DISPATCH, a 0.5-competitive, randomized algorithm. We also prove that 0.5-competitive is the best possible. DISPATCH first selects a "preferred worker" and assigns the job to this worker if it is available. The preferred worker is determined based on an optimal solution to a fractional transportation problem. If the preferred worker is not available, DISPATCH randomly selects a worker from the available workers. We show that DISPATCH maintains a uniform distribution over the workers even when the distribution over the job types is non-uniform.
Impacts of spiral-wound membrane modules in organic solvent nanofiltration applications
Creators: name: Shi, Binchu
Publisher: name: Imperial College London
Year: 2016

description: In recent years organic solvent nanofiltration has showed great potential in a number of industrial fields. A growing number of studies have been reported on development of new membrane materials, optimisation of membrane manufacturing conditions, enhancement of membrane performance and fundamental understanding of molecular transport through membranes. However, studies on spiral-wound membrane modules which are almost exclusively applied in industry are few. In this research project, experimental data on spiral-wound membrane modules of different sizes (from 1.8"x12" to 4.0"x40") in solutions covering a wide range of solute concentrations were collected under steady state operation. Then a procedure to obtain correlations describing fluid dynamics and mass transfer characteristics in the modules was developed using a limited number of experimental data for flat sheets and a 1.8"x12" module only. Furthermore, a multi-scale model for simulating the performance of processes using the modules was developed, considering the molecular transport through the membranes (membrane scale), the fluid dynamics and mass transfer characteristics in the modules (module scale) and the thermodynamic and physical properties of the solutions as a function of operating conditions (process scale). This model was used to simulate the performance of a batch concentration process using different modules under various operating conditions, and good agreement between simulation and experiments was found. In addition, the impact of ultra-high membrane permeance on process efficiency is examined in organic solvent nanofiltration and reverse osmosis as case studies via simulation, considering both concentration polarisation and pressure drops in modules. The key conclusion is that ultra-high permeance membranes will not be able to make a significant impact on process efficiency with current module designs; and the recommendation is that fresh research into module and process design is required.

description: I review models trying to explain dwarf-nova outbursts and soft X-ray transients. The disc-instability model for dwarf-novae is still in its preliminary state of development: its predictions depend very strongly on the unknown viscosity mechanism. It is also doubtful that a {\sl pure} disc-instability phenomenon will be able to describe {\sl all} types of dwarf-nova outbursts, in particular superoutbursts. The disc-instability model for SXTs suffers from the same difficulties but in addition its predictions are contradicted by observations of transient sources in quiescence. The illuminated mass-transfer model cannot describe correctly the time-scales of SXT events for main-sequence secondaries with masses less than 1$M_{\odot}$. The existence of at least three systems with $P_{\rm orb} < 10$ hr seems to rule it out as an explanation of the SXT phenomenon.

description: This Master’s thesis explores the use of a Dirichlet process (DP) prior to enhance Bayesian estimation of the parameters of multiple objects. Specifically, it focuses on a hierarchical Gaussian model where each object is linked to one parameter of interest, one noisy measurement, and one hyperparameter, and the hyperparameters are shared among objects within the same cluster. The model permits the derivation of closed-form performance bounds, enabling a quantification of performance improvements relative to the theoretically achievable performance. Our primary objective is to estimate the parameter of interest for each object based on its associated noisy measurement while leveraging the cluster structure of the hyperparameters. Because a closed-form calculation of the posterior distribution is not possible, we employ a Markov chain Monte Carlo sampling method to approximate the minimum mean square error (MMSE) estimator. This methodology yields an estimator that exploits the inherent cluster structure and, as we show through simulations, consistently achieves a mean squared error (MSE) that is lower than the MSE of the MMSE estimator for a scenario without a cluster structure. Additionally, we derive a closed-form MMSE estimator assuming known object-cluster associations and demonstrate its performance through simulations. Our approach of combining estimation and clustering demonstrates superior performance compared to the widely used method of first clustering and then performing estimation within each cluster; however, this performance advantage comes at the cost of a higher computational complexity.

description: The merger of compact binaries, especially black holes and neutron stars, is frequently invoked to explain gamma-ray bursts (GRB's). In this paper, we present three dimensional hydrodynamical simulations of the relatively neglected mergers of white dwarfs and black holes. During the merger, the white dwarf is tidally disrupted and sheared into an accretion disk. Nuclear reactions are followed and the energy release is negligible. Peak accretion rates are ~0.05 Msun/s (less for lower mass white dwarfs) lasting for approximately a minute. Many of the disk parameters can be explained by a simple analytic model which we derive and compare to our simulations. This model can be used to predict accretion rates for white dwarf and black hole (or neutron star) masses which are not simulated in this paper. Although the mergers studied here create disks with larger radii, and longer accretion times than those from the merger of double neutron stars, a larger fraction of the merging star's mass becomes part of the disk. Thus the merger of a white dwarf and a black hole could produce a long duration GRB. The event rate of these mergers may be as high as 1/Myr per galaxy.

description: We probe the dust extinction through the foreground disk of the overlapping galaxy pair UGC 5041 by analyzing B,I, and H band images. The inclined foreground disk of this infrared-selected pair is almost opaque in B at a projected distance of ~8kpc. From the images, we estimate directly the area-weighted distribution of differential near-IR extinction: it is nearly Gaussian with =0.6 and sigma=0.27. For a homogenous dust distribution and a Milky Way extinction curve, this corresponds to a face-on distribution p(tau) with a mean of =0.34 and sigma_V=0.15. For a clumpy dust model the optical depth estimate increases to =0.41 and sigma_V=0.19. Even though the galaxy pair is subject to different selection biases and our analysis is subject to different systematics, the result is consistent with existing case studies, indicating that ~0.3 is generic for late-type spirals near their half-light radii. We outline how to estimate from p(tau) by how much background quasars are underreresented, where projected within ~10kpc of nearby spirals, such as damped Ly-alpha absorbers or gravitational lenses; from our data we derive a factor of two deficit for flux-limited, optical surveys.

description: We show that if the inner regions of accretion discs in quiescent dwarf nova systems are removed by magnetic disruption or evaporated by siphon flows, the remaining disc is globally stable for mass transfer rates $\lta 10^{15}$ g s$^{-1}$. This implies that (super)outbursts in these systems have to be triggered by an enhanced mass transfer form the companion. We suggest that the lack of normal outbursts in WZ Sge results only from its low mass transfer rate and that the viscosity in its disc does not have to be few orders of magnitude lower than in other quiescent dwarf novae.

description: Novel information technologies have the potential to improve decision making. In the context of smart metering, we investigate the impact of providing households with appliance-level electricity feedback. In a randomized controlled trial, we find that the provision of appliance-level feedback creates a conservation effect of an additional 5% relative to a group receiving standard (aggregate) feedback. Consumers with poor knowledge of appliance wattage respond most strongly to appliance-level feedback, consistent with the mechanism in our model. We estimate that a smart-meter rollout will yield much larger gains in consumer surplus if appliance-level feedback can be provided.

description: We address the question of whether transport coefficients obtained from a unitary closed system setting, i.e., the standard equilibrium Green-Kubo formula, are the same as the ones obtained from a weakly driven nonequilibrium steady-state calculation. We first derive a nonequilibrium Kubo-like expression for the steady-state diffusion constant expressed as a time-integral of either a current or a conserved density nonequilibrium correlation function. This expression has certain advantages over the equilibrium Green-Kubo formula, but is not clear if it gives the same value of the diffusion constant. We then rigorously show that, if the unitary dynamics is diffusive the nonequilibrium formula indeed gives exactly the same transport coefficient. The form of finite-size correction is also predicted. Theoretical results are verified by an explicit calculation of the diffusion constant in several interacting many-body models.

description: We examine models of the mass distribution for the first known case of gravitational lensing. Several new sets of constraints are used, based on recent observations. We remodel the VLBI observations of the radio jets in the two images of Q0957+561, showing that the previously derived positions and uncertainties were incorrect. We use as additional constraints the candidate lensed pairs of galaxies identified recently with the Hubble Space Telescope. We explore a wider range of lens models than before, and find that the Hubble constant is not tightly constrained once elliptical lens models are considered. We also discuss the systematic uncertainties caused by the cluster containing the lens galaxy. We conclude that additional observations of the candidate lensed galaxies as well as direct measurements of the cluster mass profile are needed before an accurate value of the Hubble constant can be derived from this lens.

description: We investigate the dynamics and evolution of coalescing neutron stars. Although the code (Piecewise Parabolic Method) is purely Newtonian, we do include the emission of gravitational waves and their backreaction on the hydrodynamic flow. The properties of neutron star matter are described by the physical equation of state of Lattimer \& Swesty (1991). Energy loss by all types of neutrinos and changes of the electron fraction due to the emission of electron neutrinos and antineutrinos are taken into account by an elaborate ``neutrino leakage scheme''. We simulate the coalescence of two identical, cool neutron stars with a baryonic mass of $\approx\!1.6\,M_\odot$ and a radius of $\approx\!15$~km and with an initial center-to-center distance of 42~km. The initial distributions of density and electron concentration are given from a model of a cold neutron star in hydrostatic equilibrium (central temperature about $8\,{\rm MeV}$). We investigate three cases which differ by the initial velocity distribution in the neutron stars, representing different cases of the neutron star spins relative to the direction of the orbital angular momentum vector. Within about 1~ms the neutron stars merge into a rapidly spinning ($P_{\rm spin}\approx 1$~ms), high-density body ($ρ\approx 10^{14}$~g/cm$^3$) with a surrounding thick disk of material with densities $ρ\approx 10^{10}-10^{12}$~g/cm$^3$ and orbital velocities of~0.3--0.5~c. In this work we evaluate the models in detail with respect to the gravitational wave emission using the quadrupole approximation. In a forthcoming paper we will concentrate on the neutrino emission and implications for gamma-ray bursters. A maximum luminosity in excess of $10^{55}$~erg/s is reached for about 1~ms.

The development of hydro-economic models to support water resource management in the Ganga Basin in a poverty alleviation context
Creators: name: O'Keeffe, Jimmy
Publisher: name: Imperial College London
Year: 2016

description: In the last century, India has progressed from a famine prone country to one that is food self-sufficient. However, India's water resources are now under threat from a growing population with increasing demands, a changing climate and water mismanagement. Developing realistic and sustainable solutions to water resource management in India requires an understanding of local scale water use practices, leading to improved water management tools which incorporate and examine the potential impacts brought by changes in socio-economic and environmental conditions. This research involved the collection of field level data within four districts of the Indian Gangetic Basin; one of the most intensely populated areas of the world, improving understanding of irrigation water use practices in the region. Semi-structured interviews; a method more commonly used in social sciences and healthcare, were used to collect both qualitative and quantitative hydrological information on individuals' water use. The approach provides an effective and efficient method for the collection of information in data scarce regions along with detailed insights into the drivers behind many water use practices. The importance of collecting and incorporating local scale information into large scale understanding is also highlighted, with significant differences between modelled irrigation water requirements, and field reported volumes shown. The information collected and insights gained were used to develop a modelling framework that is capable of accounting for changes in water level and farmer income, resulting from variations in climate, farmer irrigation behaviour, water source and agricultural costs. Calibrated model outputs match observed values of groundwater levels and crop yield in each of the four districts. The modelling framework is used to investigate how predicted and plausible changes in boundary conditions may impact water resources and farmer livelihood. Results show that predicted future climate is likely to have little direct impact on water resources or farmer income, and may lead to increased water availability. Utilising this increase in precipitation through an additional abstraction event suggests an increase in crop yields of up to 0.5 tonnes/ha. Results also suggest additional abstraction is likely to be more sustainable in certain districts if managed appropriately, highlighting the need for local scale understanding and tailor-made solutions. This practice can also help decrease incidences of flooding, and reduce runoff resulting from high groundwater levels in aquifers. The research undertaken could have significant implications for model development, water resource management and policy, as well as poverty alleviation in India and similar developing world settings.
The genetic basis of urinary incontinence in women
Creators: name: Cartwright, James Rufus Patrick
Publisher: name: Imperial College London
Year: 2015

description: Background: Both urgency and stress urinary incontinence are heritable, with genetic factors contributing approximately half of total susceptibility. Aims: The overall aim of this project is to identify known and novel genetic polymorphisms associated with urgency and stress incontinence in women. Design: We systematically reviewed prior genetic association studies of incontinence, and other pelvic floor disorders. We then conducted a two stage GWAS, using women enrolled in NFBC1966, UK Twins, and ALSPAC for discovery, and women in six separate cohorts for replication. To prioritise likely susceptibility genes we measured gene expression in bladder biopsies, using whole genome microarrays, and PCR using custom microfluidic plates. Results: From prior studies of incontinence, and the related condition of prolapse among women, we conducted 13 meta-analyses for different polymorphisms, finding a single moderately credible association for a common variant in the ADRB3 gene associated with overactive bladder. From prior studies of lower urinary tract symptoms in men, we conducted 35 meta-analyses for different polymorphisms, finding a single moderately credible association for a common variant in the VDR gene associated with a composite of symptoms. For the GWAS discovery phase 8,997 women provided both incontinence phenotypes and genome wide genotypes. In meta-analysis, five loci included at least one genome-wide significant variant (p<5x10-8). Twelve loci were taken forward for replication, with two demonstrating robust replication. In bladder biopsies we identified 1,115 significantly differentially expressed genes between stress and urgency incontinence. In the context of the previous literature, these results suggested EN1 and EDN1 as the most likely causal genes within the two replicated GWAS significant loci. Conclusions: This work highlights many of the challenges of identification of risk variants for complex conditions such as incontinence. The discovery of two novel risk loci for incontinence represents a significant advance in understanding the pathophysiology of these conditions.
