description: Recent efforts to produce single photons via heralding have relied on creating spectrally factorable two-photon states in order to achieve both high purity and high production rate. Through a careful multimode analysis, we find, however, that spectral factorability is not necessary. Utilizing single-mode detection, a similar or better performance can be achieved with non-factorable states. This conclusion rides on the fact that even when using a broadband filter, a single-mode measurement can still be realized, as long as the coherence time of the triggering photons exceeds the measurement window of the on/off detector.

description: Craniotomy is a procedure where neurosurgeons open the patient's skull to gain direct access to the brain. The craniotomy's position defines the access path from the skull surface to the tumour and, consequently, the healthy brain tissue to be removed to reach the tumour. This is a complex procedure where a neurosurgeon is required to mentally reconstruct spatial relations of important brain structures to avoid removing them as much as possible. We propose a visualisation method using Augmented Reality to assist in the planning of a craniotomy. The goal of this study is to visualise important brain structures aligned with the physical position of the patient and to allow a better perception of the spatial relations of the structures. Additionally, a heat map was developed that is projected on top of the skull to provide a quick overview of the structures between a chosen location on the skull and the tumour. In the experiments, tracking accuracy was assessed, and colour maps were assessed for use in an AR device. Additionally, we conducted a user study amongst neurosurgeons and surgeons from other fields to evaluate the proposed visualisation using a phantom head. Most participants indeed agree that the visualisation can assist in planning a craniotomy and feedback on future improvements towards the clinical scenario was collected.

description: Transport and scattering phenomena in open quantum-systems with a continuous energy spectrum are conveniently solved using the time-dependent Schrodinger equation. In the time-dependent picture, the evolution of an initially localized wave-packet reveals the eigenstates and eigenvalues of the system under consideration. We discuss applications of the wave-packet method in atomic, molecular, and mesoscopic systems and point out specific advantages of the time-dependent approach. In connection with the familiar initial value formulation of classical mechanics, an intuitive interpretation of transport emerges. For interacting many-particle systems, we discuss the efficient calculation of the self-consistent classical transport in the presence of a magnetic field.

Beyond dissemination : a knowledge translation study to implement and evaluate a tool to support safe and effective activity in aecopd (AECOPD-Mob)
Creators: name: Ben-Ari, Ori
Publisher: name: University of British Columbia
Year: 2019

description: Background: Acute exacerbations of COPD (AECOPD) are episodes of acute deterioration in airway function and respiratory symptoms. Physical activity and exercise are important components in the recovery of patients from exacerbation. AECOPD-Mob is an evidence-based clinical decision-making tool on best practice for safe and effective exercise for hospitalized AECOPD patients. In our lab, we developed four formats of the tool (the original paper version, a Learner module, a Smartphone app and a traditional Inservice) and evaluated their usability by physical therapists (PTs) and registered nurses (RNs) working in acute care hospitals. Methods: In this study, we have examined the insights of 17 PTs and 3 RNs about the usability and intended use of the AECOPD-Mob formats. The participants were provided with access to the four AECOPD-Mob formats, completed an Evidence-Based-Practice (EBP) Barriers Questionnaire, the Post Study System Usability Questionnaire (PSSUQ) and participated in focus groups to share their thoughts and experiences. Results: We have found that the health care providers (HCPs), PTs and RNs, were satisfied with the usability learner module but were less satisfied with the usability of the Smartphone app. In addition, we originated four key themes from the focus groups: ‘HCPs’ knowledge gaps’, ‘HCPs preferences’, ’Tool quality and usability’ and ‘Improvement suggestions’ and found that the overall preferred version the AECOPD-Mob tool was the original paper version. The learner module and the Inservice were seen as interchangeable and provided necessary information, while the learner module had the benefit of being accessible at any time and, the Inservice had the benefit of better enabled discussion amongst colleagues. The app was considered challenging to use at the bedside, but the content was very favorable. Interestingly, we have found that RNs had a preference for more concise information, while PTs where looking for more broad information in the formats which give more of an overview. Conclusion: We found that PTs and RNs found the AECOPD-Mob paper version to be the easiest and most versatile format. There were concerns about using an App in a hospital setting. Future research should investigate the impact of AECOPD-Mob on patient outcomes.

description: Nowadays, many surgical procedures require preoperative planning, mostly relying on data from 3D imaging techniques like computed tomography or magnetic resonance imaging. However, preoperative assessment of this data is carried out on the PC (using classical CT/MR viewing software) and not on the patient's body itself. Therefore, surgeons need to transfer both their overall understanding of the patient's individual anatomy and also specific markers and labels for important points from the PC to the patient only with the help of imaginative power or approximative measurement. In order to close the gap between preoperative planning on the PC and surgery on the patient, we propose a system to directly project preoperative knowledge to the body surface by projection mapping. As a result, we are able to display both assigned labels and a volumetric and view-dependent view of the 3D data in-situ. Furthermore, we offer a method to interactively navigate through the data and add 3D markers directly in the projected volumetric view. We demonstrate the benefits of our approach using DIEP flap breast reconstruction as an example. By means of a small pilot study, we show that our method outperforms standard surgical planning in accuracy and can easily be understood and utilized even by persons without any medical knowledge.

description: A debris ring around the star HD 207129 (G0V; d = 16.0 pc) has been imaged in scattered visible light with the ACS coronagraph on the Hubble Space Telescope and in thermal emission using MIPS on the Spitzer Space Telescope at 70 microns (resolved) and 160 microns (unresolved). Spitzer IRS (7-35 microns) and MIPS (55-90 microns) spectrographs measured disk emission at >28 microns. In the HST image the disk appears as a ~30 AU wide ring with a mean radius of ~163 AU and is inclined by 60 degrees from pole-on. At 70 microns it appears partially resolved and is elongated in the same direction and with nearly the same size as seen with HST in scattered light. At 0.6 microns the ring shows no significant brightness asymmetry, implying little or no forward scattering by its constituent dust. With a mean surface brightness of V=23.7 mag per square arcsec, it is the faintest disk imaged to date in scattered light.

On the multiple supernova population of Arp 299: constraints on progenitor properties and host galaxy star formation characteristics

description: Throughout the last 20 years 7 supernovae (SNe) have been discovered within Arp 299. One of these is unclassified, leaving 6 core-collapse events; 2 type II, 2 type Ib, a type IIb and one object of indistinct type; Ib/IIb. We analyse the relative numbers of these types, together with their positions with respect to host galaxy properties, to investigate implications for both progenitor characteristics and star formation (SF) properties. Our findings are: 1) the ratio of 'stripped envelope' (SE) events to other type II is higher than that found in the local Universe. 2) All SE SNe are more centrally concentrated within the system than the other type II. 3) All SN environments have similar metallicities and there are no significant metallicity gradients across the system. 4) The SE SNe all fall on bright SF regions while the other type II are found to occur away from bright HII regions. We draw two different -but non-mutually exclusive- interpretations on the system and its supernovae: 1) The distribution of SNe, and the relatively high fraction of types Ib and IIb events over other type II can be explained by the young age of the most recent SF in the system, where insufficient time has expired for the observed to match the 'true' relative SN rates. This explanation provides additional independent evidence that both types Ib and IIb SNe arise from progenitors of shorter stellar lifetime and hence higher mass than other type II. 2) Given the assumption that types Ib and IIb trace higher mass progenitor stars, the relatively high frequency of types Ib and IIb to other type II, and also the centralisation of the former over the latter with respect to host galaxy light implies that in the centrally peaked and enhanced SF within this system, the initial mass function is biased towards the production of high mass stars.

A Possible Hybrid Cooling Channel for a Neutrino Factory

description: A Neutrino Factory requires an intense and well-cooled (in transverse phase space) muon beam. We discuss a hybrid approach for a linear 4D cooling channel consisting of high-pressure gas-filled RF cavities- potentially allowing high gradients without breakdown- and discrete LiH absorbers to provide the necessary energy loss that results in the required muon beam cooling. We report simulations of the channel performance and its comparison with the vacuum case; we also briefly discuss technical and safety issues associated with cavities filled with high-pressure hydrogen gas. Even with additional windows that might be needed for safety reasons, the channel performance is comparable to that of the original, all-vacuum Feasibility Study 2a channel on which our design is based. If tests demonstrate that the gas-filled RF cavities can operate effectively with an intense beam of ionizing particles passing through them, our approach would be an attractive way of avoiding possible breakdown problems with a vacuum RF channel.

Signal to noise : a discussion on the value of interactive technology in lighting design for performing arts
Creators: name: Alfredson, Craig
Publisher: name: University of British Columbia
Year: 2018

description: The goal of this thesis project was to investigate (within the confines of current technological limitations) some of the advantages and disadvantages of interactive technology in lighting for performing arts and compare it to traditional cue-based systems. To accomplish this task, the author designed, implemented, and observed interactive lighting for two contemporary dance shows. The first show, with the working title Signal to Noise, was devised with choreographers Arash Khakpour and Kelly McInnes to test various interactive technologies specifically for this thesis project. It was presented in various forms between February and April of 2013. The second show, Karoshi by Shay Kuebler, premiered at the Scotiabank Dance Centre in Vancouver, B.C. Canada on December 6th, 2012 and subsequently toured around British Columbia. The results were positive but limited. There is notable satisfaction for both the performers and the audience when there is a meaningful correlation between the action on stage and the visual and auditory environment in which it occurs. Automating that correlation using interactive technology can simplify the process for the performers on stage and the artists who create the environment. On the other hand, the complexities of programming computer-controlled interactivity can limit its usefulness. As software improves, interactive technologies will become a more valuable tool for the performing arts.

description: Given a positive real Hermitian holomorphic line bundle L over a smooth real projective manifold X, the space of real holomorphic sections of the bundle L^d inherits for every positive integer d a L^2 scalar product which induces a Gaussian measure. When X is a curve or a surface, we estimate the volume of the cone of real sections whose vanishing locus contains many real components. In particular, the volume of the cone of maximal real sections decreases exponentially as d grows to infinity.

The controls of morphodynamics in steep, aggrading channels : a flume investigation
Creators: name: Booker, William
Publisher: name: University of British Columbia
Year: 2018

description: This thesis presents the results of ten experiments conducted to examine the role grain size distributions play in the behaviour and evolution of one dimensional alluvial fans using a novel flume setup. The two grain size distributions share the same median grain size (D₅₀ = 1.42 mm), one (GSD₁) is composed of log normally distributed material from 0.25 to 5.6 mm and the other (GSD₂) is only composed of two classes: 1.4 and 2.0 mm. Images of the deposit profile and surface were used to monitor the evolution of the deposit and allow for the quantitative and qualitative assessment of behaviour, respectively. A detailed comparison of the aggrading phase of one run condition (Q = 0.1 l/s, Qb = 1 g/s) demonstrates a difference in the morphology that must originate from the grain size distribution. The addition of coarser grains in GSD₁ creates patches of immobility and allows the formation of bars more resistant to flow than in GSD₂. This reduction in transport efficiency of the material results in a higher slope and more stable bed configuration for GSD₁. More widely, this pair of experiments shows that differences in mobility may still manifest in aggrading environments. For all five pairs of experiments this difference is present. Overall, GSD₁ exhibits more stable behaviour: lower transport rates, higher slopes and later transport than GSD₂. However, the difference between the two grain size distributions decreases as discharge increases. That is, the difference is most pronounced at the lowest discharge where grains are less mobile due to the lower maximum stress and lower frequency of it occurring. This reduced mobility is due to a threshold of entrainment present in GSD₁ that is less commonly exceeded at low discharges, but that is not present to the same extent in GSD₂. Therefore, the proportion of immobile grains controls the behaviour and stability of an aggrading channel.

description: The $Λ$ $\to$ $Σ^0$ transition magnetic moment is computed in the QCD sum rules approach. Three independent tensor structures are derived in the external field method using generalized interpolating fields. They are analyzed together with the $Λ$ and $Σ^0$ mass sum rules using a Monte-Carlo-based analysis, with attention to OPE convergence, ground-state dominance, and the role of the transitions in the intermediate states. Relations between sum rules for magnetic moments of $Λ$ and $Σ^0$ and sum rules for transition magnetic moment of $Λ$ $\to$ $Σ^0$ are also examined. Our best prediction for the transition magnetic moment is $μ_{Σ^0Λ}= 1.60\pm 0.07\; μ_N$. A comparison is made with other calculations in the literature.

title: Essays in SME earnings management
Creators: name: Huang, Xing
Publisher: name: University of Reading
Year: 2023

description: This thesis includes three empirical studies in earnings management using EU samples. A large number of studies on earnings management focus on listed and/or large firms, which leaves Small and Mediumsized Enterprises (SMEs), especially European SMEs, understudied. However, SMEs play a vital role in the development of the EU’s economy. They are also more informationally opaque and less creditworthy compared to large enterprises, which could lead to more incentives in earnings management around debt financing. Existing literature that explores SME earnings management substantially focuses on firm-level determinants. Though bank finance is the dominant external source of finance for European SMEs, the banking effects on SME earnings management are rarely explored due to limited data availability. Thus, using unique matched data on SME-bank relationships in EU countries, the first study of the thesis investigates the external effectsfrom the banking market competition perspective. The main results show supporting evidence to the existence of a positive effect of bank market power on SME earnings management. The results also show that the positive effect is more pronounced for SMEs that are smaller-sized, more liquidity-constrained, or have fewer growth opportunities. The second study of the thesis focuses on another external aspect of earnings management determinants, which is country-level lending infrastructure. The comprehensive framework of country-level characteristics is derived from Berger and Udell (2006)1 which includes information, legal, social and regulatory environments. The results in this study show that SME earnings management is more prevalent in countries that have better credit information sharing, more effective legal systems, higher stock of social capital, and more stringent regulatory environments. After examining the external influence of bank market power and lending infrastructure on SME earnings management, the third study of the thesis explores the effects of SME earnings management at firm-level. Specifically, since financial constraint is one of the most serious problems faced by EU SMEs, the third study sheds light on the effect of SME earnings management on its cost of bank credit. In the setting of a less financially constrained SME sample, the main finding suggests that the SME’s extent of earnings management is negatively associated with its cost of debt. In sum, the empirical evidence in this thesis jointly contributes to the current earnings management literature and related policy-making by expanding the understanding of the European SME earnings management behaviours and raising attention to enhance the quality of monitoring mechanisms.

description: We use RHESSI high-resolution imaging and spectroscopy observations from ~5 to 100 keV to characterize the hot thermal plasma during the 2002 July 23 X4.8 flare. These measurements of the steeply falling thermal X-ray continuum are well fit throughout the flare by two distinct isothermal components: a super-hot (T > 30 MK) component that peaks at ~44 MK and a lower-altitude hot (T < 25 MK) component whose temperature and emission measure closely track those derived from GOES measurements. The two components appear to be spatially distinct, and their evolution suggests that the super-hot plasma originates in the corona, while the GOES plasma results from chromospheric evaporation. Throughout the flare, the measured fluxes and ratio of the Fe and Fe-Ni excitation line complexes at ~6.7 and ~8 keV show a close dependence on the super-hot continuum temperature. During the pre-impulsive phase, when the coronal thermal and non-thermal continua overlap both spectrally and spatially, we use this relationship to obtain limits on the thermal and non-thermal emission.

description: The transport of Brownian particles in a slit geometry in the presence of an arbitrary two-dimensional periodic energy landscape and driven by an external force or convected by a flow field is investigated by means of macrotransport theory. Analytical expressions for the probability distribution and the average migration angle of the particles are obtained under the Fick-Jackobs approximation. The migration angle is shown to differ from the orientation angle of the driving field and to strongly depend on the physical properties of the suspended species, thus providing the basis for vector chormatography, in which different species move in different directions and can be continuously fractionated. The potential of microfluidic devices as a platform for partition-induced vector chromatography is demonstrated by considering the particular case of a piece-wise constant, periodic potential that, in equilibrium, induces the spontaneous partition of different species into high and low concentration stripes, and which can be easily fabricated by patterning physically or chemically one of the surfaces of a channel. The feasibility to separate different particles of the same and different size is shown for systems in which partition is induced via 1g-gravity and Van der Waals interactions in physically and chemically patterned channels, respectively.

description: Finite temperature lattice simulations of quantum chromodynamics (QCD) are sensitive to the hadronic mass spectrum for temperatures below the "critical" temperature T_c ~ 160 MeV. We show that a recent precision determination of the QCD trace anomaly shows evidence for the existence of a large number of hadron states beyond those known from experiment. The lattice results are well represented by an exponentially growing hadron mass spectrum up to a temperature T = 155 MeV. Using simple parametrizations we show how one may estimate the total spectral weight in these yet undermined states.

description: We present an algorithm for computing the $p$-component of the automorphic representation arising from a cuspidal newform $f$ for a prime $p$. This is equivalent to computing the restriction to the decomposition group at $p$ of the $\ell$-adic Galois representations attached to $f$ for any $\ell\neq p$. The situation is most interesting when $p^2$ divides the level of $f$, in which case the $p$-component could be supercuspidal. In the supercuspidal case, the local component is induced from an irreducible character of a compact-mod-center subgroup of $\text{GL}_2(\mathbf{Q}_p)$; our algorithm outputs both the group and the irreducible character. We provide examples which illustrate how the local Galois representation can be completely read off from the local component.

description: Almost 40 years ago, Gribov and colleagues at the Leningrad Nuclear Physics Institute developed the ideas that led to the Dokhsitzer-Gribov-Altarelli-Parisi the Baltisky-Fadin-Kuraev-Lipatov equations. These equations describe the evolution of the distributions for quarks and gluon inside a hadron to increased resolution scale of a probe or to smaller values of the fractional momentum of a hadronic constituent. I motivate and discuss the generalization required of these equations needed for high energy processes when the density of constituents is large. This leads to a theory of saturation realized by the Color Glass Condensate

Oases in the grid: The gardens of postwar Milanese middle-class housing

description: The essay investigates the Milanese street-front gardens of post-WWII middle-class housing. Spread around the city by hectic developers, these gardens reflect specific cultural- al, political and social conditions of Italy’s industrial capital during the economic miracle. Street-facing gardens are an essential feature of modern middle-class condominiums. They reflected the modernist urban vision of a park-city and the Milanese tradition of the street facade; they encapsulate the bourgeois culture with its urge for representative decorum and the freedom of architectural experimentation; their image was used as a marketing tool in real estate advertisement but also as an argument in negotiation for the building licence. In Post-WWII Milan urban nature radically changed its connotation: from a hygienic device, it transformed into a status symbol, and the Milanese started to take care of gardens precisely because of their decorative importance. Even though they are private, they are designed to be looked at from the street, and therefore they make an important part of the everyday urban experience. Beyond their speculative nature, the gardens of Milanese condominiums transformed the urban landscape, bringing density together with well-cared nature into the city streets. The essay explores this phenomenon through a series of distant and close-up views as if following a wandering gaze through the streets of the city. Cover image: Condominium in Piazzale Bacone, arch.

The monstrosity of text : gender tensions in early modern English pamphlets, 1550 - 1650
Creators: name: Bailie, Krista
Publisher: name: University of British Columbia
Year: 2018

description: The advent of print and specifically the pamphlet in the sixteenth-century created a new moment for the monster, a time of religious upheaval and gender tensions in which the pamphlet emerged as a way for the literate but no longer only the wealthy and privileged to engage in public discourse. My thesis considers the use of the monster in early modern print in England, arguing that it is the reappropriation of the visual and rhetorical offerings of earlier versions of the monster which makes it a culturally convenient symbol in a time of political instability and revolution. Drawing on an extended history of the symbol of the monster, this work considers the impulse to frame behavior inside the notion of the monstrous, and the ways an imagined monster can appear out of nowhere and disrupt society. As part of a larger concern at the time around women and their conduct, the pamphlet operated as a cultural technology that could sanction, reform or deny the categories of normalcy and deviancy, a tool that simultaneously created and contained the monster. The prolific publishing of pamphlets by men in the late sixteenth and early seventeenth centuries (namely those focusing on monstrous births, controversial fashions, political involvement and sexual deviance) evidences not only the desire to control the behaviour of women but also the ways in which women were resisting this control through retaliatory pamphleteering and publishing, petitioning and self-fashioning. By using these monstrous bodies in print, the stories and the pamphlets become part of a larger narrative of internal and external monstrousness within society. I argue that the content of these pamphlets provides historical evidence of women’s considered political engagement and agency, a disruption that invited the monster in to do the cultural work of embodying religious, political and gender tensions in revolutionary England.

description: We present a detection of a broad Ly-alpha absorber (BLA) with a matching O VI line in the nearby universe. The BLA is detected at z = 0.01028 in the high S/N spectrum of Mrk 290 obtained using the Cosmic Origins Spectrograph. The Ly-alpha absorption has two components, with b(HI) = 55 +/- 1 km/s and b(HI) = 33 +/- 1 km/s, separated in velocity by v ~ 115 km/s. The O VI, detected by FUSE at z = 0.01027, has a b(OVI) = 29 +/- 3 km/s and is kinematically well aligned with the broader HI component. The different line widths of the BLA and OVI suggest a temperature of T = 1.4 x 10^5 K in the absorber. The observed line strength ratios and line widths favor an ionization scenario in which both ion-electron collisions and UV photons contribute to the ionization in the gas. Such a model requires a low-metallicity of -1.7 dex, ionization parameter of log U ~ -1.4, a large total hydrogen column density of N(H) ~ 4 x 10^19 cm^-2, and a path length of 400 kpc. The line of sight to Mrk 290 intercepts at the redshift of the absorber, a megaparsec scale filamentary structure extending over 20 deg in the sky, with several luminous galaxies distributed within 1.5 Mpc projected distance from the absorber. The collisionally ionized gas in this absorber is likely tracing a shock-heated gaseous structure, consistent with a few different scenarios for the origin, including an over-dense region of the WHIM in the galaxy filament or highly ionized gas in the extended halo of one of the galaxies in the filament. In general, BLAs with metals provide an efficient means to study T ~ 10^5 - 10^6 K gas in galaxy halos and in the intergalactic medium. A substantial fraction of the baryons "missing" from the present universe is predicted to be in such environments in the form of highly ionized plasma.

Pairwise dwarf galaxy formation and galaxy downsizing: some clues from extremely metal-poor Blue Compact Dwarf galaxies

description: Some of the extremely metal-poor Blue Compact Dwarf galaxies (XBCDs) in the nearby universe form galaxy pairs with remarkably similar properties. This fact points to an intriguing degree of synchronicity in the formation history of these binary dwarf galaxies and raises the question as to whether some of them form and co-evolve pairwise (or in loose galaxy groups), experiencing recurrent mild interactions and minor tidally induced star formation episodes throughout their evolution. We argue that this hypothesis offers a promising conceptual framework for the exploration of the retarded previous evolution and recent dominant formation phase of XBCDs.

Strongly Interacting Matter Matter at Very High Energy Density: 3 Lectures in Zakopane
Creators: name: McLerran, Larry
Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: These lectures concern the properties of strongly interacting matter at very high energy density. I begin with the Color Glass Condensate and the Glasma, matter that controls the earliest times in hadronic collisions. I then describe the Quark Gluon Plasma, matter produced from the thermalized remnants of the Glasma. Finally, I describe high density baryonic matter, in particular Quarkyonic matter. The discussion will be intuitive and based on simple structural aspects of QCD. There will be some discussion of experimental tests of these ideas.
