description: We select eight nearby AGNs which, based on previous work, appear to be Compton-thin in the line of sight. We model with MYTORUS their broadband X-ray spectra from 20 individual observations with $Suzaku$, accounting self-consistently for Fe K$α$ line emission, as well as direct and scattered continuum from matter with finite column density and solar Fe abundance. Our model configuration allows us to measure the global, out of the line of sight, equivalent hydrogen column density separately from that in the line of sight. For 5 out of 20 observations (in 3 AGNs) we find that the global column density is in fact $\gtrsim 1.5 \times 10^{24}$cm$^{-2}$, consistent with the distant scattering matter being Compton-thick. For a fourth AGN, 2 out of 5 observations are also consistent with being Compton-thick, although with large errors. Some of these AGNs have been reported to host relativistically broadened Fe K$α$ emission. Based on our modeling, the Fe K$α$ emission line is not resolved in all but two $Suzaku$ observations, and the data can be fitted well with models that only include a narrow Fe K$α$ emission line.

The components of a quality assurance program for smaller hospitals
Creators: name: Finnie, Carol Jean
Publisher: name: University of British Columbia

description: The components of a quality assurance program for smaller hospitals in British Columbia have been defined. These components have been defined by a comparison of the normative standards as determined in the literature and by a survey of administrators. Sixteen administrators of predominantly acute-care, accredited, 20-50-bed hospitals in B.C. were surveyed. Twelve of these administrators were surveyed twice. A new requirement for accreditation was introduced by the Canadian Council on Hospital Accreditation (C.C.H.A.) called the Quality Assurance Standard (1985). This Standard required that quality assurance (QA) programs be established in every department or service in the hospital. The Standard does not give a clear description of the QA functions for each individual department in a smaller hospital. An important and relevant list of specific functions for a QA program were identified at various C.C.H.A. seminars held across Canada in late 1983 and early 1984. The literature review indicated that there were a number of controversial issues affecting the implementation of the QA Standard. In spite of many methodological problems associated with quality measurement and assurance, most hospitals will adopt a quality assurance model. The first survey asked the administrators to define the purpose, goals and objectives of a QA program. They were also asked to determine the QA functions for four areas: hospital board, dietary, nursing and pharmacy. Administrators were asked to identify who in the hospital is primarily responsible for the overall QA program and for the QA program in four areas; the problems and benefits encountered when trying to implement a QA program; and their opinion of the new QA requirements for accreditation. The second survey asked the administrators to assign a priority to those functions identified in Round I. The empirical findings were then compared with the normative standards. With some exceptions, the empirical data were consistent with the normative standards. The empirical findings shows that there are problems related to implementing a QA program but at the same time there are a number of benefits related to the program. The priority ratings of the functions indicated areas of high or low importance to the administrator. It is likely that these priority ratings are useful for planning when alternatives must be considered during this time of fiscal restraint. Government policies along with the strong voluntary support of accreditation programs make it vitally important that suitable models for implementing QA are developed. The Doll model is suggested as a basis for implementing QA. Further areas for research are presented.
Nonlocal protons and deuterons opposed to disorder: a single-crystal neutron diffraction study of KH0.76D0.24CO3 and a theoretical framewok

description: We show with neutron diffraction that a single-crystal of potassium hydrogen deuterium carbonate at room temperature, namely KH$_{0.76}$D$_{0.24}$CO$_3$, is isomorphous with the KHCO$_3$ and KDCO$_3$ derivatives. Protons and deuterons are not disordered particles located at definite sites and Bragg peaks are best fitted with separate H and D sublattices. We propose a theoretical framework for nonlocal observables and macroscopic states compatible with the crystal field.

description: This paper reexamines Raymond Chandler’s influential critique of British Golden Age detective fiction, which promoted hard-boiled realism against the perceived artifice of Golden Age stories. While acknowledging the impact of Chandler’s essay “The Simple Art of Murder”, I submit that his critique oversimplifies the complexity and enduring appeal of works by authors such as Agatha Christie and Dorothy L. Sayers. Contemporary scholarship reveals that Golden Age detective fiction engaged deeply with social, psychological, and gender issues through sophisticated narratives. By reassessing these works and challenging Chandler’s reductive categorization, this paper seeks to provide a more nuanced understanding of the literary value and cultural significance of Golden Age detective fiction.

description: The determination of the coil-globule transition of a polymer is generally based on the reconstruction of scaling laws, implying the need for samples from a rather wide range of different polymer lengths $N$. The spectral point of view developed in this work allows for a very parsimonious description of all the aspects of the finite-size coil-globule transition on the basis of the first two Rouse (cosine) modes only, shedding new light on polymer theory. Capturing the relevant configuration path features, the proposed approach enables to determine the state of a polymer without the need of any information about the polymer length or interaction strength. Importantly, we propose an experimental implementation of our analysis that can be easily performed with modern fluorescent imaging techniques, and would allow differentiation of coil or globule conformations by simply recording the positions of three discernible loci on the polymer.

description: This paper attempts to provide a theoretical consideration of the strategies employed in my translation of Luciano Bianciardi’s 1962 novel La Vita Agra into English. A brief review of the multiple connotations of context and its relation to translation precedes an attempt to define Bianciardi’s literary style and discuss some specific areas of difficulty encountered in rendering the novel’s style in English, focusing on grammatical and syntactical equivalence, and the role of Italian dialect. Throughout, Eric Mosbacher’s 1965 English translation has been used as a point of comparison. The paper concludes with a more extended discussion of the wider intertextual system in which La Vita Agra can be located, and the possible implications this has for a translation of the novel.
The Global Precipitation Measurement Mission: Product Validation and Model Evaluation Studies

Publisher: name: University of Leicester

Subjects: Uncategorized

description: The Global Precipitation Measurement (GPM) mission, an international satellite constellation of microwave remote sensors that observes global precipitation, aims to improve our understanding of the Earth’s water cycle and energy budget. This thesis validates GPM’s constellation-reference sensors over the British Isles, studies the global diurnal cycle of precipitation using GPM, and evaluates climate model performance in simulating the global diurnal cycle. These studies are of paramount importance to science and society, by providing necessary understanding of GPM’s mid-latitude performance prior to its application to the global diurnal cycle of precipitation, which climate models notoriously fail to accurately represent. Identifying climate model shortcomings with accurate observations is critical to improving their realism in simulating the future climate. This thesis first validates the constellation reference NASA-JAXA GPM Core Observatory (CO) Dual-frequency Precipitation Radar (DPR) and GPM Microwave Imager (GMI) precipitation retrievals over the British Isles against the Met Office ground-based radar network. The DPR and combined DPR-GMI retrievals underestimate British-Irish precipitation by 31% and 21%, respectively, with a tendency for winter bias enhancements due to erroneous surface precipitation retrievals in the presence of low freezing levels. The second study investigates the global precipitation diurnal cycle using the global-gridded Integrated Multi-satellitE Retrievals for GPM (IMERG) product, derived from the GPM passive microwave constellation, spaceborne infrared and ground-based gauge sensors. The diurnal cycle is identified to be stronger over land, where precipitation peaks at ~16–24 local solar time (LST), than over ocean, where precipitation peaks at ~0–8 LST (~8–15 LST) over open (coastal) waters. The final study evaluates the global diurnal precipitation representation of three Coupled Model Intercomparison Project (CMIP6) models and the ECMWF Reanalysis (ERA5) using IMERG. Three CMIP6 models and ERA5 are found to simulate precipitation earlier than observed, with difficulty in capturing the nocturnal propagation of precipitation over mountainous regions.

description: Let $X$ be a smooth projective curve of genus $g\geq 2$ over the complex numbers. A holomorphic triple $(E_1,E_2,ϕ)$ on $X$ consists of two holomorphic vector bundles $E_1$ and $E_2$ over $X$ and a holomorphic map $ϕ:E_2 \to E_1$. There is a concept of stability for triples which depends on a real parameter $σ$. In this paper, we determine the Hodge polynomials of the moduli spaces of $σ$-stable triples with $\rk(E_1)=3$, $\rk(E_2)=1$, using the theory of mixed Hodge structures. This gives in particular the Poincaré polynomials of these moduli spaces. As a byproduct, we recover the Hodge polynomial of the moduli space of odd degree rank 3 stable vector bundles.

description: We propose a novel statistical approach to the analysis of experimental data obtained in nucleus-nucleus collisions at high energies which borrows from methods developed within the context of Random Matrix Theory. It is applied to the detection of correlations in momentum distributions of emitted particles. We find good agreement between the results obtained in this way and a standard analysis based on the method of effective mass spectra and two-pair correlation function often used in high energy physics. The method introduced here is free from unwanted background contributions.

description: We computed potentials between static color sources from the six lowest representations of G(2) lattice gauge theory, in numerical simulations with the Wilson action on asymmetric lattices with nonperturbatively estimated values of the bare anisotropy. We present evidence for (approximate) Casimir scaling of the obtained intermediate string tensions. The agreement with the Casimir-scaling prediction improves by increasing the coupling beta in the weak-coupling region above the crossover observed in G(2) gauge theory. The result naturally fits into confinement models with magnetic disorder and vacuum domain structure, but may represent a challenge for other approaches.

description: The recent discovery of universal principles underlying many complex networks occurring across a wide range of length scales in the biological world has spurred physicists in trying to understand such features using techniques from statistical physics and non-linear dynamics. In this paper, we look at a few examples of biological networks to see how similar questions can come up in very different contexts. We review some of our recent work that looks at how network structure (e.g., its connection topology) can dictate the nature of its dynamics, and conversely, how dynamical considerations constrain the network structure. We also see how networks occurring in nature can evolve to modular configurations as a result of simultaneously trying to satisfy multiple structural and dynamical constraints. The resulting optimal networks possess hubs and have heterogeneous degree distribution similar to those seen in biological systems.

description: We calculate the thermodynamic quantities (correlation functions , correlation length xi, spin susceptibility chi, and specific heat C_V) of the frustrated one-dimensional spin-half J2-J2 Heisenberg ferromagnet, i.e. for J2< 0.25|J1|, using a rotation-invariant Green's-function formalism and full diagonalization of finite lattices. We find that the critical indices are not changed by J2, i.e., chi = y_0 T^{-2} and xi = x_0 T^{-1} at T \to 0. However, the coefficients y_0 and x_0 linearly decrease with increasing J2 according to the relations y_0=(1-4J_2/|J_1|)/24 and x_0 =(1-4J_2/|J_1|)/4, i.e., both coefficients vanish at J2=0.25|J1| indicating the zero-temperature phase transition that is accompanied by a change of the low-temperature behavior of chi (xi) from chi \propto T^{-2} (xi \propto T^{-1}) at J2 < 0.25|J1| to chi \propto T^{-3/2} (xi \propto T^{-1/2}) at J2 = 0.25|J1|. In addition, we detect the existence of an additional low-temperature maximum in the specific heat when approaching the critical point at J2=0.25|J1|.

description: In principle, by accepting the idea of a non-zero vacuum energy, the physical vacuum of present particle physics might represent a preferred reference frame. By treating this quantum vacuum as a relativistic medium, the non-zero energy-momentum flow expected in a moving frame should effectively behave as a small thermal gradient and could, in principle, induce a measurable anisotropy of the speed of light in a loosely bound system as a gas. We explore the phenomenological implications of this scenario by considering a new class of dedicated ether-drift experiments where arbitrary gaseous media fill the resonating optical cavities. Our predictions cover most experimental set up and should motivate precise experimental tests of these fundamental issues.

description: We study the twisted-Hopf-algebra symmetries of observer-independent canonical spacetime noncommutativity, for which the commutators of the spacetime coordinates take the form [x^{mu},x^{nu}]=i theta^{mu nu} with observer-independent (and coordinate-independent) theta^{mu nu}. We find that it is necessary to introduce nontrivial commutators between transformation parameters and spacetime coordinates, and that the form of these commutators implies that all symmetry transformations must include a translation component. We show that with our noncommutative transformation parameters the Noether analysis of the symmetries is straightforward, and we compare our canonical-noncommutativity results with the structure of the conserved charges and the "no-pure-boost" requirement derived in a previous study of kappa-Minkowski noncommutativity. We also verify that, while at intermediate stages of the analysis we do find terms that depend on the ordering convention adopted in setting up the Weyl map, the final result for the conserved charges is reassuringly independent of the choice of Weyl map and (the corresponding choice of) star product.

We consider the generic Schwarzschild-AdS black holes (SAdS), the generic Dp-brane, the Klebanov-Tseytlin (KT) geometry, and the N=2* theory. The formula is the "shear mode" result and is not fully trustable, but it may be helpful to learn some generic behaviors about the relaxation time. For example, a simple formula summarizes all known results for SAdS, and a single expression summarizes the results for the Dp-brane and the KT geometry.

Multiple stellar populations in Globular Clusters: collection of information from the Horizontal Branch

description: The majority of the inhomogeneities in the chemical composition of Globular Cluster (GC) stars appear due to primordial enrichment by hot-CNO cycled material processed in stars belonging to a first stellar generation. Either massive AGB envelopes subject to hot bottom burning, or the envelopes of massive fastly rotating stars could be the progenitors. In both cases, the stars showing chemical anomalies must have also enhanced helium abundance, and we have proposed that this higher helium could be at the basis of the many different morphologies of GC horizontal branches (HB) for similar ages and metallicities. The helium variations have been beautifully confirmed by the splitting of the main sequence in the clusters omega Cen and NGC 2808, but this effect can show up only for somewhat extreme helium abundances. Therefore it is important to go on using the HB morphology to infer the number ratio of the first to the second generation in as many clusters as possible. We exemplify how it is possible to infer the presence of a He-rich stellar component in different clusters thanks to different HB features (gaps, RR Lyr periods and period distribution, ratio of blue to red stars, blue tails). In many clusters at least 50% of the stars belong to the second stellar generation, and in some cases we suspect that the stars might all belong to the second generation. We shortly examine the problem of the initial mass function required to achieve the observed number ratios and conclude that: 1) the initial cluster must have been much more massive than today's cluster, and 2) formation of the second stellar generation mainly in the central regions of the cluster may help in obtaining the desired values.

Implications of a rapidly varying FRB in a globular cluster of M81

description: A repeating source of fast radio bursts (FRBs) is recently discovered from a globular cluster of M81. Association to a globular cluster (or other old stellar systems) suggests that strongly magnetized neutron stars, which are the most likely objects responsible for FRBs, are born not only when young massive stars undergo core-collapse, but also by mergers of old white dwarfs. We find that the fractional contribution to the total FRB rate by old stellar populations is at least a few percent, and the precise fraction can be constrained by FRB searches in the directions of nearby galaxies, both star-forming and elliptical ones. Using very general arguments, we show that the activity time of the M81-FRB object is between 10^4 and 10^6 years, and more likely of order 10^5 years. The energetics of radio outbursts puts a lower limit on the magnetic field strength of 10^{13} G, and the spin period > 0.2 sec, thereby ruling out the source being a milli-second pulsar. The upper limit on the persistent X-ray luminosity (provided by Chandra), together with the high FRB luminosity and frequent repetitions, severely constrains (or rules out) the possibility that the M81-FRB is a scaled-up version of giant pulses from Galactic pulsars. Finally, the 50 ns variability time of the FRB lightcurve suggests that the emission is produced in a compact region inside the neutron star magnetosphere, as it cannot be accounted for when the emission is at distances > 10^{10} cm.

Gauge invariant as well as gauge non-invariant interactions are considered to show that the FP factor needs to be modified in more general cases and expressions for these modifications are derived. In particular we show that a gauge invariant theory does not necessarily imply the familiar FP factor for proper quantization.

description: The genus Exobasidium includes a number of species that are pathogenic to members of the Ericales, including blueberries (Vaccinium spp.), and Exobasidium leaf spot is an emerging concern for commercial blueberry production. Atypical Exobasidium leaf spot-like symptoms were observed in wild V. angustifolium (lowbush blueberry) in eastern Newfoundland and Labrador, Canada, beginning in 2016. A fungus with morphological characteristics typical of Exobasidium spp. was isolated from symptomatic tissue. The ITS regions from five isolates, and the LSU regions from two, were sequenced and compared with publicly available Exobasidium spp. sequences, including from E. maculosum, cause of Exobasidium leaf spot on V. angustifolium. The isolates collected in this study were genetically distinct from all isolates of E. maculosum, as well as from the other Exobasidium spp. sequences available, suggesting that the isolates described here represent a genetically distinct population belonging to the genus Exobasidium.

description: We present a family of nonlocal games in which the inputs the players receive are continuous. We study three representative members of the family. For the first two a team sharing quantum correlations (entanglement) has an advantage over any team restricted to classical correlations. We conjecture that this is true for the third member of the family as well.

description: Transition metals, Fe, Co and Ni, are the canonical systems for studying the effect of external perturbations on ferromagnetism. Among these, Ni stands out as it undergoes no structural phase transition under pressure. Here we have investigated the long-debated issue of pressure-induced magnetisation drop in Ni from first-principles. Our calculations confirm an abrupt quenching of magnetisation at high pressures, not associated with any structural phase transition. We find that the pressure substantially enhances the crystal field splitting of Ni-$3d$ orbitals, driving the system towards a new metallic phase violating the Stoner Criterion for ferromagnetic ordering. Analysing the charge populations in each spin channel, we show that the next nearest neighbour interactions play a crucial role in quenching ferromagnetic ordering in Ni and materials alike.

A study of a dominant suppressor of the purple eye-color mutant in Drosophila melanogaster
Creators: name: Firth, James Dawrant
Publisher: name: University of British Columbia
Year: 2010

description: The subject of this study is a new dominant suppressor mutation Su(pr) which acts on the purple eye-colour mutant (pr) of Drosophila a melanogaster. The Induction of Su (pr) was originally associated with the synthesis of a compound-2R chromosome In SD72/cn bw females. The suppression of p_ was first observed in combination with a homologous pr bearing compound-2L chromosome. Suppressed-pr flies appeared to have a fully wild eye phenotype. The intention of this study was to determine the chromosomal constitution necessary for Su(pr) induction, and to map the suppressor site. To do this, many compound-2R chromosomes were synthesized from several combinations of standard seconds. It was found that SD72 must be present to produce a suppressing compound-2R. The SD72 second carries a pericentric inversion that results in a duplication of 2L heterochromatIn, and an associated deficiency of 2R heterochromatin in the compound-2R S u (p r) chromosome. Suppression, therefore, Is associated with the pericentric inversion found only on SD72. The role of this segmental aneuploidy was studied by detaching several C(2L)pr: C(2R)SD72/,cn bw suppressed strains such that both arms of the Su(pr) compound autosome were recovered independently and established in standard strains. Suppressing and non-suppressing detachment products were recovered with a frequency that varied according to the compound-2R Su(pr) strain from which they were derived. The chromosome mechanics involved in the process of C(2R)SD72/cn bw formation and subsequent detachment implicates alterations to a segment of proxlmial 2R heterochromatin from SD72 in Su(pr) Induction. Loss of Su(pr) in the detachment process correlates predominantly with deletions generated In 2R heterochromatIn. Recombination mapping relative to the two visible heterochromatic markers, Iight and rolled, revealed that Su(pr) Iies to the left of rolIed. SpectrophotometrIc measurements of eye pigments revealed that suppressed-pr and suppressed-pru bw flies had pigment levels that exceeded the wild type. The lethal allele prc4. was not found to be suppressible.

description: Developing quantum technologies requires the control and understanding of the non-equilibrium dynamics of quantum information in many-body systems. Local information propagates in the system by creating complex correlations known as information scrambling, as this process prevents extracting the information from local measurements. In this work, we develop a model adapted from solid-state NMR methods, to quantify the information scrambling. The scrambling is measured via time-reversal Loschmidt echoes (LE) and Multiple Quantum Coherences experiments that intrinsically contain imperfections. Considering these imperfections, we derive expressions for out-of-time-order correlators (OTOCs) to quantify the observable information scrambling based on measuring the number of active spins where the information was spread. Based on the OTOC expressions, decoherence effects arise naturally by the effects of the nonreverted terms in the LE experiment. Decoherence induces localization of the measurable degree of information scrambling. These effects define a localization cluster size for the observable number of active spins that determines a dynamical equilibrium. We contrast the model's predictions with quantum simulations performed with solid-state NMR experiments, that measure the information scrambling with time-reversal echoes with controlled imperfections. An excellent quantitative agreement is found with the dynamics of quantum information scrambling and its localization effects determined from the experimental data. The presented model and derived OTOCs set tools for quantifying the quantum information dynamics of large quantum systems (more than $10^{4}$ spins) consistent with experimental implementations that intrinsically contain imperfections.

description: We develop a theory of optical transitions in Coulomb impurity-doped two-dimensional transition metal dichalcogenide monolayers and study the transitions from the spin-resolved valence band to the (Coulomb) donor and acceptor impurities under the influence of a synthetic valley-selective magnetic field produced by a mechanical strain. It is shown that the optical properties of the system are determined by the strength of the synthetic magnetic field, which uncovers an experimental tool, which can be used to manipulate the properties of two-dimensional materials in valley magneto-optoelectronics.

A Polytropic Model of Quark Stars

description: A polytropic quark star model is suggested in order to establish a general framework in which theoretical quark star models could be tested by observations. The key difference between polytropic quark stars and the polytropic model studied previously for normal (i.e., non-quarkian) stars is related to two issues: (i) a constant term representing the contribution of vacuum energy may be added in the energy density and the pressure for a quark star, but not for a normal star; (ii) the quark star models with non-vanishing density at the stellar surface are not avoidable due to the strong interaction between quarks. The first one implies that the vacuum inside a quark star is different from that outside, while the second one is relevant to the effect of color confinement. The polytropic equations of state are stiffer than that derived in conventional realistic models (e.g., the bag model) for quark matter, and pulsar-like stars calculated with a polytropic equation of state could then have high maximum masses (> 2 M_sun). Quark stars can also be very low massive, and be still gravitationally stable even if the polytropic index, n, is greater than 3. All these would result in different mass-radius relations, which could be tested by observations. In addition, substantial strain energy would develop in a solid quark star during its accretion/spindown phase, and could be high enough to take a star-quake. The energy released during star-quakes could be as high as ~ 10^{47} ergs if the tangential pressure is ~ 10^{-6} higher than the radial one.
