The number, luminosity, and mass density of spiral galaxies as a function of surface brightness
Creators: name: McGaugh, Stacy
Publisher: name: arXiv
Year: 1995
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: I give analytic expressions for the relative number, luminosity, and mass density of disc galaxies as a function of surface brightness. These surface brightness distributions are asymmetric, with long tails to lower surface brightnesses. This asymmetry induces systematic errors in most determinations of the galaxy luminosity function. Galaxies of low surface brightness exist in large numbers, but the additional contribution to the integrated luminosity density is modest, probably 10 -- 30%.

description: The purpose of this study is to evaluate two facets of the Norfolk Police Department's Police Assisted Community Enforcement, or PACE, program. While there has been much research on how community policing affects officer and citizen attitudes, there has been very little that focuses on organizational aspects of implementing this philosophy. This research uses a survey instrument to examine how Norfolk's structuring of their community policing program may have an impact on the way the officers involved cooperate with one another. Levels of cooperation and training are measured, as well as the effects that years on the department and education have on these variables. The analyses reveal that while most of the officers believe that community policing is a worthwhile program, Norfolk's structuring of may have resulted in low levels of cooperation between the PACE and Patrol officers.
Homogeneous quantum groups and their easiness level

description: Given a closed subgroup $G\subset U_N^+$ which is homogeneous, in the sense that we have $S_N\subset G\subset U_N^+$, the corresponding Tannakian category $C$ must satisfy $span(\mathcal{NC}_2)\subset C\subset span(P)$. Based on this observation, we construct a certain integer $p\in\mathbb N\cup\{\infty\}$, that we call "easiness level" of $G$. The value $p=1$ corresponds to the case where $G$ is easy, and we explore here, with some theory and examples, the case $p>1$. As a main application, we show that $S_N\subset S_N^+$ and other liberation inclusions, known to be maximal in the easy setting, remain maximal at the easiness level $p=2$ as well.

Development of novel connection methods between precast concrete panels
Creators: name: Vella, Jean Paul
Publisher: name: Imperial College London
Year: 2017

description: This thesis addresses the design and behaviour of narrow cast in-situ joints between precast concrete elements in which continuity of reinforcement is achieved through overlapping headed bars. The use of headed bars minimises the required reinforcement lap length and hence joint width, thereby, maximising the area of precast concrete units. Confining reinforcement in the form of transverse bars and vertical shear studs is installed within the joint. Improved understanding of the behaviour of such joints is obtained by means of experimental testing and numerical analysis. In total, 32 tensile specimens and five flexural specimens were tested. The main longitudinal reinforcement in all specimens consisted of 25 mm diameter headed bars with 70 mm square heads. The tests investigated the influence on joint performance of concrete strength, confining shear studs, transverse bar arrangement, headed bar lap length and spacing, and out-of-plane offset of precast planks. For tensile specimens, a lap length of 100 mm with four 16 mm transverse bars and concrete compressive strength of 28 MPa was sufficient for headed bar yield. Ductile flexural failure, with headed bar yield, was achieved with the same lap length, two 20 mm transverse bars and concrete compressive strength of 39 MPa. A nonlinear finite element model (NLFEM) is presented with results showing that it captures the behaviour of the joint well. Additional parametric studies carried out with the validated NLFEM provide otherwise unavailable insights into joint behaviour. In conjunction with an appropriate safety format, the model is considered suitable for the design of standard joint configurations. Analytical models based on the strut-and-tie method and upper bound plasticity are presented. The models were found to give reasonable predictions of joint strength, but are not capable of fully capturing the observed joint behaviour. An improved strut and tie design method is suggested and recommendations are made for optimising joint design.

description: We suggest an approach for simulating theories with a sign problem that relies on optimisation of complex integration contours that are not restricted to lie along Lefschetz thimbles. To that end we consider the toy model of a one-dimensional Bose gas with chemical potential. We identify the main contribution to the sign problem in this case as coming from a nearest neighbour interaction and approximately cancel it by an explicit deformation of the integration contour. We extend the obtained expressions to more general ones, depending on a small set of parameters. We find the optimal values of these parameters on a small lattice and study their range of validity. We also identify precursors for the onset of the sign problem. A fast method of evaluating the Jacobian related to the contour deformation is proposed and its numerical stability is examined. For a particular choice of lattice parameters, we find that our approach increases the lattice size at which the sign problem becomes serious from $L \approx 32$ to $L \approx 700$. The efficient evaluation of the Jacobian ($O(L)$ for a sweep) results in running times that are of the order of a few minutes on a standard laptop.

$^{13}CO(J = 1 -- 0)$ Depression in Luminous Starburst Mergers
Creators: name: Taniguchi, Yoshiaki

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

description: It is known that the class of luminous starburst galaxies tends to have higher $R =^{12}CO(J=1--0)/^{13}CO(J=1--0)$ integrated line intensity ratios ($R>20$) than normal spiral galaxies ($R \sim 10$). Since most previous studies investigated only $R$, it remains uncertain whether the luminous starburst galaxies are overabundant in $^{12}$CO or underabundant in $^{13}$CO. Here we propose a new observational test to examine this problem. Our new test is to compare far-infrared luminosities [$L$(FIR)] with those of $^{12}$CO and $^{13}CO [L(^{12}CO)$ and $L(^{13}CO)$, respectively]. It is shown that there is a very tight correlation between $L(^{12}CO)$ and L(FIR), as found in many previous studies. However, we find that the $^{13}$CO luminosities of the high-R galaxies are lower by a factor of three on the average than those expected from the correlation for the remaining galaxies with ordinary $R$ values. Therefore, we conclude that the observed high $R$ values for the luminous starburst galaxies are attributed to their lower $^{13}$CO line intensities.

description: We present an optical/near IR selected catalog of 79 clusters distributed over an area of 5.1~square~degrees. The catalog was constructed from images obtained with the 4-Shooter CCD mosaic camera on the Hale 5m telescope operating in ``scan" mode. The survey, hereafter known as the Palomar Distant Cluster Survey (PDCS), was conducted in two broad band filters that closely resemble~$V$ and~$I$. The $4σ$ limiting magnitudes for our 300 s exposures are~$\sim$~23.8~($V$) and~22.5~($I$). A matched filter algorithm was developed and employed to identify the cluster candidates by using positional and photometric data simultaneously. The clusters cover the range $0.2 \simless z \simless 1.2$, based on the redshift estimates derived in the cluster detection procedure. An accurate selection function is generated from extensive simulations. We find that the cumulative surface density of clusters with richness class R $\ge$ 1 is about a factor of 5 higher than the extrapolated density of R $\ge$ 1 Abell clusters. The PDCS results are consistent with a constant comoving density of clusters to $z \simless 0.6$, albeit at the above high density level. Constraints on cluster abundances at $z > 0.6$ will be possible with the acquisition of spectroscopic redshifts for a large subset of these cluster candidates. We also present a supplemental catalog of 28 clusters that do not satisfy all our selection criteria but which include some of the most distant systems detected in the survey. Finding charts for all 107 cluster candidates are provided.

Mass Flow and Accretion through gaps in Accretion Discs
Creators: name: Kley, Willy
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We study the structure and dynamics of the gap created by a protoplanet in an accretion disc. The hydrodynamic equations for a flat, two-dimensional, non-selfgravitating protostellar accretion disc with an embedded, Jupiter sized protoplanet on a circular orbit are solved. To simulate possible accretion of mass onto the protoplanet we continually remove mass from the interior of the planet's Roche lobe which is monitored. Firstly, it is shown that consistent results independent on numerical issues (such as boundary or initial conditions, artificial viscosity or resolution) can be obtained. Then, a detailed parameter study delineates the influence of the disc viscosity and pressure on the magnitude of the accretion rate. We find that, even after the formation of a gap in the disc, the planet is still able to accrete more mass from the disc. This accretion occurs from regions of the disc which are radially exterior and interior to the planet's orbital radius. The rate depends on the magnitude of the viscosity and vertical thickness of the disc. For a disc viscosity alpha=10^{-3} and vertical thickness H/r=0.05 we estimate the time scale for the accumulation of one Jupiter mass to be of order hundred thousand years. For a larger(smaller) viscosity and disc thickness this accretion rate is increasing(decreasing). For a very small viscosity (alpha < 5 10^{-4}) the mass accretion rate through the gap onto the planet is markedly reduced, and the corresponding accretion time scale becomes larger than the viscous evolution time of the disc.

The Confluent System Formalism: II. The Growth History of Objects

Year: 1995
Subjects: subject: Astrophysics (astro-ph)

description: With the present paper we conclude the presentation of a semianalytical model of hierarchical clustering of bound virialized objects formed by gravitational instability from a random Gaussian field of density fluctuations. In paper I, we introduced the basic tool, the so-called ``confluent system'' formalism, able to follow the evolution of bound virialized objects in the peak model. This was applied to derive the mass function of objects. In the present paper, we calculate other important quantities characterizing the growth history of objects. This model is compared with a similar one obtained by Lacey \& Cole (1993) following the Press \& Schechter (1974) approach. The interest of the new modeling presented here is twofold: 1) it is formally better justified as far as peaks are more reasonable seeds of objects than the indetermined regions in the Press \& Schechter prescription, and 2) it distinguishes between merger and accretion enabling us to unambiguously define the formation and destruction of objects and to estimate growth rates and characteristic times not available in the previous approach.

description: We model the $\lya$ forest in a spatially flat, CDM model with $Ω=0.4$, with an Eulerian hydrodynamic simulation, and find that the intergalactic, photoionized gas collapses into sheet-like and filamentary structures which produce absorption lines like those observed in the $\lya$ forest. A typical filament is $\sim 1 h^{-1} \mpc$ long with thickness $\sim 50-100 h^{-1} \kpc$ (in proper units), and baryonic mass $\sim 10^{10} h^{-1} \msun$. The gas temperature increases with time as structures with larger velocities collapse gravitationally. The predicted distributions of column densities and b-parameters of the absorption lines agree with the observed ones, and their evolution is consistent with our model if the ionizing background has an approximately constant intensity between $z=2$ and $z=4$. We also predict the distribution of transmitted flux and its correlation along a spectrum and on parallel spectra, and the \heii flux decrement as a function of redshift. We predict a correlation length of $\sim 80 h^{-1}\kpc$ perpendicular to the line of sight for features in the Lyman alpha forest. In order to reproduce the observed number of lines and average flux transmission, the baryon content of the clouds may need to be significantly higher than in previous models because of the low densities we predict. If the background intensity $\jhi$ is at least that predicted from the observed quasars, $Ω_b$ needs to be $\sim 0.025 h^{-2}$, higher than expected by light element nucleosynthesis; the model also predicts that most of the baryons at $z>2$ are in $\lya$ clouds, and that the rate at which the baryons move to more overdense regions is slow.

description: Down syndrome (DS) is caused by trisomy of human chromosome 21 (Hsa21). DS is a gene dosage disorder that results in multiple phenotypes including congenital heart defects. This clinically important cardiac pathology is the result of a third copy of one or more of the approximately 230 genes on Hsa21, but the identity of the causative dosage-sensitive genes and hence mechanisms underlying this cardiac pathology remain unclear. Here, we show that hearts from human fetuses with DS and embryonic hearts from the Dp1Tyb mouse model of DS show reduced expression of mitochondrial respiration genes and cell proliferation genes. Using systematic genetic mapping, we determined that three copies of the dual-specificity tyrosine phosphorylation-regulated kinase 1A (Dyrk1a) gene, encoding a serine/threonine protein kinase, are associated with congenital heart disease pathology. In embryos from Dp1Tyb mice, reducing Dyrk1a gene copy number from three to two reversed defects in cellular proliferation and mitochondrial respiration in cardiomyocytes and rescued heart septation defects. Increased dosage of DYRK1A protein resulted in impairment of mitochondrial function and congenital heart disease pathology in mice with DS, suggesting that DYRK1A may be a useful therapeutic target for treating this common human condition.

The equilibrium models were taken from models evolved from the protostellar birthline to the ZAMS for masses in the range 1 to 4 solar masses. The nonlinear analysis allows us to define the instability strip of PMS stars in the HR diagram. These models are used to constrain the internal structure of young stars and to test evolutionary models. We compare our results with observations of the best case of a pulsating young star, HR~5999, and we also identify possible candidates for pulsational variability among known Herbig Ae/Be stars which are located within or close to the instability strip boundaries.

description: We explore the physics of the disordered XYZ spin chain using two complementary numerical techniques: exact diagonalization (ED) on chains of up to 17 spins, and time-evolving block decimation (TEBD) on chains of up to 400 spins. Our principal findings are as follows. First, the clean XYZ spin chain shows ballistic energy transport for all parameter values that we investigated. Second, for weak disorder there is a stable diffusive region that persists up to a critical disorder strength that depends on the XY anisotropy. Third, for disorder strengths above this critical value energy transport becomes increasingly subdiffusive. Fourth, the many-body localization transition moves to significantly higher disorder strengths as the XY anisotropy is increased. We discuss these results, and their relation to our current physical picture of subdiffusion in the approach to many-body localization.

description: The formation, inner properties, and spatial distribution of galaxy groups and clusters are closely related to the background cosmological model. We use numerical simulations of variants of the CDM model with different cosmological parameters and distinguish relaxed objects from recent mergers using the degree of virialisation. Mergers occur mostly in deep potential wells and mark the most important structure formation processes. As consequence, the autocorrelation function of merged halos has a higher amplitude and is steeper than that of the virialized clusters. This can be directly connected to the same result found from the observation of luminous infrared galaxies; they are as well more strongly correlated and can primarily be identified with ongoing merging events.

description: A proposed paradigm for out-of-equilibrium quantum systems is that an analogue of quantum phase transitions exists between parameter regimes of qualitatively distinct time-dependent behavior. Here, we present evidence of such a transition between dynamical phases in a cold-atom quantum simulator of the collective Heisenberg model. Our simulator encodes spin in the hyperfine states of ultracold fermionic potassium. Atoms are pinned in a network of single-particle modes, whose spatial extent emulates the long-range interactions of traditional quantum magnets. We find that below a critical interaction strength, magnetization of an initially polarized fermionic gas decays quickly, while above the transition point, the magnetization becomes long-lived, due to an energy gap that protects against dephasing by the inhomogeneous axial field. Our quantum simulation reveals a non-equilibrium transition predicted to exist but not yet directly observed in quenched s-wave superconductors.

Electrochemical processing of single-walled carbon nanotubes and related materials
Creators: name: Hodge, Stephen Anthony
Publisher: name: Imperial College London
Year: 2012

description: The remarkable properties of single-walled carbon nanotubes (SWNTs) and potential applications are hindered by current solution-phase processing strategies. The initial dissolution of SWNTs remains a fundamental challenge, reliant on aggressive chemistry or ultrasonication and lengthy ultracentrifugation. In this thesis, a simple non-aqueous electrochemical reduction process that leads to spontaneous dissolution of individualised SWNTs from raw, unprocessed powders is outlined. The intrinsic electrochemical stability and conductivity of these nanoparticles allows their electrochemical dissolution from a pure SWNT cathode to form solutions of well-defined nanoparticle anions with characteristic charge density. Other than a reversible change in redox/solvation state, there is no obvious chemical functionalisation of the structure, suggesting an analogy to conventional atomic electrochemical dissolution. The heterogeneity of as-synthesised SWNT samples leads to the sequential dissolution of distinct fractions over time. Initial preferential dissolution of defective nanotubes and carbonaceous debris provides a simple, non-destructive means to purify raw materials without recourse to the usual, damaging, competitive oxidation reactions. During early stage developments, the process showed remarkable affinity for dissolving metallic SWNTs, providing a potentially scalable route for separation by electronic character, vital for many applications. However, selectivity was lost with significantly increased process yields (complete dissolution) following several optimisations. Subsequently, the electrochemical deposition of SWNTs is proposed as a new route to selectively plate specific SWNT species and avoid unwanted functionalisations that occur when exposing reduced SWNTs to different atmospheres. Finally, the extension of electrochemical processing to related materials including activated and graphitic nanocarbons, metallic and metal chalcogenide nanomaterials was also investigated, with great promise for the development of new applications.
title: Attention Deficit Hyperactivity Disorder: Considering the Impact of Educational Institutions and Teacher Perceptions
Creators: name: Glass, Cynthia S.
Publisher: name: Old Dominion University
publisherIdentifier: https://ror.org/04zjtrb98
publisherIdentifierScheme: ROR
Year: 1999

description: This research examines teacher perceptions about the nature of Attention Deficit Hyperactivity Disorder ("ADHD") and the teaching strategies used to work with students who display ADHD behaviors. It also examines the relationship between classroom size and perception of incidence of ADHD within the classroom.

Results indicate that older and more experienced teachers are more flexible than younger, less experienced teachers in their teaching strategies when working with students who display ADHD behaviors. Teachers who received information about ADHD from their school administration utilized flexible methods more often than those who did not receive information. The proportion of students identified as displaying ADHD behaviors generally increases with classroom size. No relationship was found between perception of the nature of ADHD and teaching strategies.

Robust model selection between population growth and multiple merger coalescents

description: We study the effect of biological confounders on the model selection problem between Kingman coalescents with population growth, and Xi-coalescents involving simultaneous multiple mergers. We use a low dimensional, computationally tractable summary statistic, dubbed the singleton-tail statistic, to carry out approximate likelihood ratio tests between these model classes. The singleton-tail statistic has been shown to distinguish between them with high power in the simple setting of neutrally evolving, panmictic populations without recombination. We extend this work by showing that cryptic recombination and selection do not diminish the power of the test, but that misspecifying population structure does. Furthermore, we demonstrate that the singleton-tail statistic can also solve the more challenging model selection problem between multiple mergers due to selective sweeps, and multiple mergers due to high fecundity with moderate power of up to 30%.

description: We present a striking new Hubble Space Telescope (HST) observation of the rich cluster Abell 2218 taken with the Wide-Field and Planetary Camera (WFPC2). HST's restored image quality reveals a sizeable number of gravitationally-lensed features in this cluster, significantly more than had been identified using ground-based telescopes. The brightest arcs are resolved by HST and show internal features enabling us to identify multiply-imaged examples, confirming and improving the mass models of the cluster determined from ground-based observations. Although weak lensing has been detected statistically in this and other clusters from ground-based data, the superlative resolution of HST enables us to individually identify weakly distorted images more reliably than hitherto, with important consequences for their redshift determination. Using an improved mass model for the cluster calibrated with available spectroscopy for the brightest arcs, we demonstrate how inversion of the lensing model can be used to yield the redshift distribution of $\sim$80 faint arclets to $R\simeq25$. We present a new formalism for estimating the uncertainties in this inversion method and review prospects for interpreting our results and verifying the predicted redshifts.

Mechanisms of water transport through soil from a pervaporative irrigation system
Creators: name: Todman, Lindsay Caroline
Publisher: name: Imperial College London
Year: 2013

description: This thesis presents the results of an investigation into the transport of water through soil from a pervaporative irrigation tube. This irrigation system uses a selective polymer membrane that allows water to cross by the process of pervaporation, which releases water into the soil in vapour phase. The polymer membrane is formed into a tube, buried in the soil and filled with saline water. The selectivity of the membrane retains salt within the tube whilst water is released, so the system treats the water and distributes it for irrigation simultaneously. The distribution of water from the system, rather than the treatment efficiency, was the focus of this project. Although in the field the system will interact with the plants it irrigates, in this work, for simplicity, plants were neglected. Instead a series of laboratory experiments were conducted to quantify the flux from the pervaporative tube in different soil types and in different humidity conditions. The results of these experiments highlighted, for the first time, the significance of vapour flow and condensation in the soil during the pervaporative irrigation process. Soil types with high water sorption at low relative humidity (e.g. saline sand) had an increased amount of condensation in the soil which resulted in an increased flux from the pipe. A moisture sorption isotherm was a useful predictor of this behavior. A numerical model was then developed to simulate the experimental findings. Experimental results had demonstrated that diffusion and condensation of water vapour through the soil were significant processes hence these were the main focus of the modelling work. Liquid flow was also simulated when the water content in the soil was sufficient. To simplify the representation of the pervaporative tube it was assumed that the membrane acted as a 100% humidity boundary in the soil thus it was assumed that it was the transport of water through the soil that limited the flux of water from the pervaporative tube rather than the membrane structure itself. The similarity between the observed and simulated results supported the basis of this conceptual understanding of pervaporative irrigation. This research raises a number of further questions regarding the interaction between plants and pervaporative membranes. These include how plants might interact with vapour flows through the soil and the influence of soil salinity on the interaction between the pervaporative membrane and the plant roots.
Use of ionic liquids as a means of recovering value from key organic waste streams in Nigeria
Creators: name: Thompson, Feyisetan Oluremi
Publisher: name: Imperial College London
Year: 2013

description: Two novel processes based on ionic liquid methodology, including steps to recover the ionic liquids for reuse and recycle, are developed for the recovery of key value components from food wastes: namely glycosaminoglycans (GAGs) from seafood waste (scallop gut) and chitin-glucan complexes from cider yeast wastes. Both these components are high-added value materials in nutraceuticals and the chitin- glucan complexes are of particular interest because they are recovered from a vegetarian source. GAG recovery from scallop gut involves treatment of the wet waste with the ionic liquid, HBetNTf2, in a low temperature (30oC) process to separate the insoluble GAG mixture from other components of the waste, which are soluble. The important aspects of this process from the point of view of economic viability are: (i) it is a low-temperature process, (ii) the extraction of the unwanted components occurs quickly, (iii) the product GAGs are obtained in good yield, and (iv) all solvents used can be recovered. The recovery of chitin-glucan involves enzymatic pre-treatment of the cider yeast waste to give a digested pellet from which the complex can be recovered by treatment with the IL, BMIMCl. Two low temperature ionic liquid processes (TESA/TESAC and P6,6,6,14 Cl) for re-refining waste lubricant oils to recover base oils, of sufficient quality to be reused in lubricant applications, are also developed. The TESA/TESAC process is based on a reversible reaction from a solvent, TESA, in which the base oil is soluble to an ionic liquid, TESAC in which the base oil is insoluble. The conversion occurs when carbon dioxide is passed through the solvent and reversed by heating above 50oC. In the P6,6,6,14 Cl process the base oils are recovered from a direct solution of the hydrocarbon content of the waste in the ionic liquid. In both processes all solvents used can be recovered for reuse.
