description: We present results of our investigation into student understanding of the physical significance and utility of the Boltzmann factor in several simple models. We identify various justifications, both correct and incorrect, that students use when answering written questions that require application of the Boltzmann factor. Results from written data as well as teaching interviews suggest that many students can neither recognize situations in which the Boltzmann factor is applicable, nor articulate the physical significance of the Boltzmann factor as an expression for multiplicity, a fundamental quantity of statistical mechanics. The specific student difficulties seen in the written data led us to develop a guided-inquiry tutorial activity, centered around the derivation of the Boltzmann factor, for use in undergraduate statistical mechanics courses. We report on the development process of our tutorial, including data from teaching interviews and classroom observations on student discussions about the Boltzmann factor and its derivation during the tutorial development process. This additional information informed modifications that improved students' abilities to complete the tutorial during the allowed class time without sacrificing the effectiveness as we have measured it. These data also show an increase in students' appreciation of the origin and significance of the Boltzmann factor during the student discussions. Our findings provide evidence that working in groups to better understand the physical origins of the canonical probability distribution helps students gain a better understanding of when the Boltzmann factor is applicable and how to use it appropriately in answering relevant questions.

description: We report some new interesting features of the dynamics of a string axion field (i.e., a (pseudo-)scalar field with tiny mass with sine-Gordon-type self-interaction) around a rotating black hole in three respects. First, we revisit the calculation of the growth rate of superradiant instability, and show that in some cases, overtone modes have larger growth rates than the fundamental mode with the same angular quantum numbers when the black hole is rapidly rotating. Next, we study the dynamical evolution of the scalar field caused by the nonlinear self-interaction, taking attention to the dependence of the dynamical phenomena on the axion mass and the modes. The cases in which two superradiantly unstable modes are excited simultaneously are also studied. Finally, we report on our preliminary simulations for gravitational wave emission from the dynamical axion cloud in the Schwarzschild background approximation. Our result suggests that fairly strong gravitational wave burst is emitted during the bosenova, which could be detected by the ground-based detectors if it happens in Our Galaxy or nearby galaxies.

description: This is a scanned copy of a document on temperature stratification for Kogelberg and Silvermine Nature Reserve. The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities in state plantations would affect climate, water conservation and erosion, and was later expanded to include studies of fynbos ecology, fire and alien species. Studies from the 1930s to the early 1990s saw the accumulation of a large amount of data dealing with fire experiments, detailed vegetation plot surveys, rare plant surveys and ecological studies, hydrological studies and the development of management plans for catchments around the Western Cape.  SAEON now houses the archive of data collected by the Jonkershoek Forestry Research Center, which was originally held by the Council for Scientific and Industrial Research (CSIR).

description: This thesis presents three self-contained essays that emphasize the relevance of household heterogeneity and distributional implications in the analysis of business cycle dynamics and fiscal policy. In Chapter 2, I investigate the impact of redistributive taxation on private borrowing constraints and the cross-sectional distributions of consumption and income. I show that tax policy can have a substantial effect on households’ access to private credit markets in the sense that borrowing constraints become tighter when redistribution is increased. Chapter 3 studies the role of household heterogeneity in the transmission of government expenditure shocks and provides a mechanism that naturally generates state-dependent fiscal multipliers. In Chapter 4, I demonstrate that interpersonal comparison is an important driver of short-run credit movements.

description: The decay rate of the Higgs decay $H \to Z γ$ is evaluated at the one-loop level in the $SO(5)\times U(1)$ gauge-Higgs unification. Although an infinite number of loops with Kaluza-Klein states contribute to the decay amplitude, there appears the cancellation among the loops, and the decay rate is found to be finite and non-zero. It is found that the decay rate is well approximated by the decay rate in the standard model multiplied by $\cos^2θ_H$, where $θ_H$ is the Aharonov-Bohm phase induced by the vacuum expectation value of an extra-dimensional component of the gauge field.

description: Pediatric lung transplantation has advanced over the years, providing a potential life-prolonging therapy to patients with cystic fibrosis. Despite this, many challenges in lung transplantation remain and result in worse outcomes than other solid organ transplants. As CF lung disease progresses, children and their caregivers are often simultaneously preparing for lung transplantation and end of life. In this article, we will discuss the current barriers to success in pediatric CF lung transplantation as well as approaches to end of life care in this population.

description: Complex quantum systems consisting of large numbers of strongly coupled states exhibit characteristic level repulsion, leading to a non-Poisson spacing distribution which can be described by Random Matrix Theory. Scattering resonances observed in ultracold atomic and molecular systems exhibit similar features as a consequence of their energy level structure. We study how the overlap between Feshbach resonances affects the distribution of resonance spacings. The spectrum of strongly overlapping resonances turns out to be non-Poisson even when the assumptions of Random Matrix Theory are not fulfilled, but the spectrum is also not completely chaotic and tends towards being semi-Poisson.

description: We investigate the resilience of symmetry-protected topological edge states at the boundaries of Kitaev chains in the presence of a bath which explicitly introduces symmetry-breaking terms. Specifically, we focus on single-particle losses and gains, violating the protecting parity symmetry, which could generically occur in realistic scenarios. For homogeneous systems, we show that the Majorana mode decays exponentially fast. By the inclusion of strong disorder, where the closed system enters a many-body localized phase, we find that the Majorana mode can be stabilized substantially. The decay of the Majorana converts into a stretched exponential form for particle losses or gains occuring in the bulk. In particular, for pure loss dynamics we find a universal exponent $α\simeq 2/3$. We show that this holds both in the Anderson and many-body localized regimes. Our results thus provide a first step to stabilize edge states even in the presence of symmetry-breaking environments.

description: Background: A zucchini disease outbreak with unusual symptoms associated with Pseudomonas syringae clade 2b was identified in Bundaberg, Australia during autumn 2016. To investigate the genetic diversity of the 11 Australian isolates obtained from the outbreak, the genomes were compared to the publicly available P. syringae strains in phylogroup 2. Results: Average nucleotide identity refined the P. syringae clade 2b-a into four clusters (Cluster A, B, C1 and C2), an expansion from the previously identified A, B and C. Australian isolates were in Cluster A, C1 and C2. Genomic analyses highlighted several key factors that may contribute to the virulence of these isolates. Six orthologous groups, including three virulence factors, were associated with P. syringae phylogroup 2 cucurbit-infecting strains. A region of genome plasticity analysis identified a type VI secretion system pathway in clade 2b-a strains which could also contribute to virulence. Pathogenicity assays on isolates KL004-k1, KFR003-1 and 77-4C, as representative isolates of Cluster A, C1 and C2, respectively, determined that all three isolates can infect pumpkin, squash, watermelon and zucchini var. Eva with different levels of disease severity. Subsequently, type III effectors were investigated and four type III effectors (avrRpt2, hopZ5, hopC1 and hopH1) were associated with host range. The hopZ effector family was also predicted to be associated with disease severity. Conclusions: This study refined the taxonomy of the P. syringae clade 2b-a, supported the association between effector profile and pathogenicity in cucurbits established in a previous study and provides new insight into important genomic features of these strains. This study also provided a detailed and comprehensive resource for future genomic and functional studies of these strains.

description: Gamma-ray bursts (GRBs) are the most luminous electromagnetic explosions in the Universe, which emit up to $8.8\times10^{54}$ erg isotropic equivalent energy in the hard X-ray band. The high luminosity makes them detectable out to the largest distances yet explored in the Universe. GRBs, as bright beacons in the deep Universe, would be the ideal tool to probe the properties of high-redshift universe: including the cosmic expansion and dark energy, star formation rate, the reionization epoch and the metal enrichment history of the Universe. In this article, we review the luminosity correlations of GRBs, and implications for constraining the cosmological parameters and dark energy. Observations show that the progenitors of long GRBs are massive stars. So it is expected that long GRBs are tracers of star formation rate. We also review the high-redshift star formation rate derived from GRBs, and implications for the cosmic reionization history. The afterglows of GRBs generally have broken power-law spectra, so it is possible to extract intergalactic medium (IGM) absorption features. We also present the capability of high-redshift GRBs to probe the pre-galactic metal enrichment and the first stars.

description: We derive equations for the mean entropy and the mean internal energy in the low-Mach-number temperature stratified turbulence (i.e., for turbulent convection or stably stratified turbulence), and show that turbulent flux of entropy is given by ${\bf F}_s=\overlineρ \, \overline{{\bf u} s}$, where $\overlineρ$ is the mean fluid density, $s$ are fluctuations of entropy and overbars denote averaging over an ensemble of turbulent velocity field, ${\bf u}$. We demonstrate that the turbulent flux of entropy is different from the turbulent convective flux, ${\bf F}_c=\overline{T} \, \overlineρ \, \overline{{\bf u} s}$, of the fluid internal energy, where $\overline{T}$ is the mean fluid temperature. This turbulent convective flux is well-known in the astrophysical and geophysical literature, and it cannot be used as a turbulent flux in the equation for the mean entropy. This result is exact for low-Mach-number temperature stratified turbulence and is independent of the model used. We also derive equations for the velocity-entropy correlation, $\overline{{\bf u} s}$, in the limits of small and large Peclet numbers, using the quasi-linear approach and the spectral tau approximation, respectively. This study is important in view of different applications to the astrophysical and geophysical temperature stratified turbulence.

description: Die letzten Jahrzehnte haben bisher nicht gekannte soziokulturelle und rechtliche Errungenschaften gebracht, unter anderem die Entkriminalisierung von Homosexualität und die Anerkennung der Menschenrechte sexueller Minderheiten in vielen Ländern dieser Welt. Doch diese Errungenschaften wurden auch einer heftigen Kritik unterzogen, indem aufgezeigt wurde, wie sie zugleich zu queerem Rassismus, Homonationalismus und einer imperialistischen Agenda der global gay politics führen. Der vorliegende Essay ist ein Versuch, diese verstörenden Entwicklungen innerhalb queerer Politiken in ihrer Komplexität darzulegen. Zugleich wird argumentiert, dass eine Politik des Anti-Homonationalismus mit einer Staatsphobie verbunden ist, die dazu führt, dass der ausschließliche Fokus auf queeren Rassismus im globalen Norden es unmöglich macht, homophobe und heteronormative Praxen und Strukturen innerhalb migrantischer Communities ebenso wie in der postkolonialen Welt zu adressieren.
description: The past decades have been ones of unprecedented sociocultural and legal gains for queer politics. But these achievements have been accompanied by a severe critique of queer racism and of the imperialist agenda of global gay politics. While supportive of the urgency of critiquing the complicities of Western queer politics in neoliberal, imperial discourses, the essay argues that the politics of anti-homonationalism represents a form of state-phobia so that the sole focus on queer racism in the global North neglects to address heterosexism and homophobia in diasporic and postcolonial contexts.

description: Reduced heart rate variability (HRV) suggests autonomic imbalance in the control of heart rate and is associated with unfavorable cardiometabolic outcomes. We examined whether antenatal corticosteroid (ANCS) exposure had long-term programming effects on heart rate variability (HRV) in adolescents born with very low birth weight (VLBW).

description: Stellar magnetic field measurements using Zeeman broadening in total intensity (Stokes I) spectra are complementary to measurements using circularly polarized (Stokes V) spectra. Stokes V measurements provide information about the large-scale geometry of a magnetic field. Zeeman broadening measurements are sensitive to smaller regions of very strong magnetic field, which can cancel out in Stokes V. Here we present results for two K-type stars with weak but detectable magnetic fields: epsilon Eri and HD 189733. These observations, obtained with SPIRou at the CFHT, illustrate the advantage of spectropolarimetry in the IR. They also allow direct comparisons between Zeeman broadening measurements and longitudinal magnetic measurements from Stokes V. As expected there are large differences between the longitudinal magnetic field and the magnetic field from Zeeman broadening, but combining these approaches could provide more complete pictures of stellar magnetic fields in future studies.

L'étude de la stratification architecturale dans les monuments historiques. Cas du pont el kantara à Constantine
Creators: name: HAOUACHA, Ferial
Publisher: name: Zenodo
Year: 2015
Subjects: Stratification - monument historique -histoire constructive- histoire diachronique- morphologie- ordre chronologique

description: La réflexion conduite dans le présent travail sur le phénomène de la stratification architecturale découle de la tendance à prendre "la valeur historique" des monuments patrimoniaux détachée de sa continuité chronologique, pour faire référence à une identité jugée emblématique et représentative d'une région et/ou d'un peuple donnés. Un tel positionnement nous engage dans un débat conflictuel quant à la nature même de la dimension historique du patrimoine architectural, et l'objectif conventionnel intergénérationnel visé par son entreprise. A travers notre présente étude, on va aborder la stratification comme phénomène morphologique engendré par un soubassement logique et intelligible, ancré dans la matérialité des monuments historiques. Ainsi, on va mettre en avant essentiellement deux aspects de la question; d'un côté comment appréhender une telle configuration sur le plan perceptif, et ceux en mettant de l'ordre dans ce qui semble à priori être complexe et concaténé par ce qu'on appelle communément l'ensemble des unités stratigraphiques. D'autre part, on s'intéressera à l'identification des rapports entre les différentes unités stratigraphiques en question, en faisant ressortir la causalité structurale, et l'organisation chronologique entre elles. En définitive, on mettra l'accent sur la stratification comme incarnation matérielle de l'histoire constructive diachronique des monuments, et l'impact d'un tel comportement comme intervention sur l'existant dans la perspective de la conservation du patrimoine architectural.
title: A realist approach to categorizing musical works
Creators: name: Cantabrana, Cody
Publisher: name: University of Glasgow
Year: 2022

description: This thesis seeks to advance our comprehension of musical ontology as it pertains to realism from a platonist vantagepoint. Similar to other areas of ontological inquiry, such as fictional and mathematical objects, musical ontology is a specific field in philosophy of art that disputes the categorical nature and identity of musical objects. Much like its fictional and mathematical counterparts, categorizing works of music has been amply discussed by realists. In order to advance our understanding in this field, I will examine the categorical nature of such objects and the consequences realists face upon application. My dissertation will be separated in two distinct parts: one developing and one applying my platonist account. The first three chapters develop a certain stripe of musical realism that has previously been unexplored in the literature. In order to achieve this aim, Chapter One lays out a taxonomy of ontologies that catalogs realists, non-realists (nominalism and anti-realism), and arealist accounts. Chapters Two and Three provide two realist accounts hitherto undiscussed in the taxonomy. What makes both accounts enticing to the musical realist is that they endorse a property theory of musical works, which stands in contrast to its popular cousin, type/token theory. In particular, Chapter Two unpacks the property theory from an aristotelian perspective, while Chapter Three does so from a platonist perspective. Chapter Three provides the account that I develop and endorse. The purpose of application—contained in the last three chapters—is meant to not only show my account’s implications, but also exhibit how these can render the account advantageous. Chapter Four will explain how realists should approach and contemplate the role of the musical score. Chapter Five will provide a realist response to the role of artificial intelligence in musical composition, and Chapter Four will provide a realist’s modest definition of music. My goal is to showcase my account’s fruitfulness in these applications, as well as to demonstrate how it can facilitate further questions about the nature of musical works and the categories to which they belong.

description: Preterm newborns exposed to intrauterine inflammation are at increased risk of neurodevelopmental disorders. We hypothesized that adverse outcomes are more strongly associated with a combination of antenatal and postnatal inflammation than with either of them alone.

description: Let ${\mathcal B}^{\, p, \, p^{\prime}, \, {\mathcal H}}_{N, n}$ be a conformal block, with $n$ consecutive channels $χ_ı$, $ı= 1, \cdots, n$, in the conformal field theory $\mathcal{M}^{\, p, \, p^{\prime}}_N \! \times \! \mathcal{M}^{\mathcal{H}}$, where $\mathcal{M}^{\, p, \, p^{\prime}}_N$ is a $\mathcal{W}_N$ minimal model, generated by chiral fields of spin $1, \cdots, N$, and labeled by two co-prime integers $p$ and $p^{\prime}$, $1 < p < p^{\prime}$, while $\mathcal{M}^{\mathcal{H}}$ is a free boson conformal field theory. $\mathcal{B}^{\, p, \, p^{\prime}, \mathcal{H}}_{N, n}$ is the expectation value of vertex operators between an initial and a final state. Each vertex operator is labelled by a charge vector that lives in the weight lattice of the Lie algebra $A_{N-1}$, spanned by weight vectors $ω_1, \cdots, ω_{N-1}$. We restrict our attention to conformal blocks with vertex operators whose charge vectors point along $ω_1$. The charge vectors that label the initial and final states can point in any direction. Following the $\mathcal{W}_N$ AGT correspondence, and using Nekrasov's instanton partition functions without modification, to compute $\mathcal{B}^{\, p, \, p^{\prime}, \mathcal{H}}_{N, n}$, leads to ill-defined expressions. We show that restricting the states that flow in the channels $χ_ı$, $ı= 1, \cdots, n$, to states labeled by $N$ partitions that satisfy conditions that we call $N$-Burge partitions, leads to well-defined expressions that we identify with $\mathcal{B}^{\, p, \, p^{\prime}, \, \mathcal{H}}_{N, n}$. We check our identification by showing that a specific non-trivial conformal block that we compute, using the $N$-Burge conditions satisfies the expected differential equation.

description: Congenital diaphragmatic hernia (CDH) involves lung hypoplasia and pulmonary hypertension (PH). Post-natal Perflubron ventilation induces lung growth. This phenomenon is called Perflubon-induced lung growth (PILG). However, it does not appear to ameliorate PH in CDH. We aim to determine the effect of PILG on pulmonary vascular remodeling in neonates with CDH and PH requiring extracorporeal membrane oxygenation (ECMO).

description: BACKGROUND: Children with complex airway problems see multiple specialists. To improve outcomes and coordinate care, we developed a multidisciplinary Children's Airway Center. For children with tracheostomies, aspects of care targeted for improvement included optimizing initial hospital discharge, promoting effective communication between providers and caregivers, and avoiding tracheostomy complications.

METHODS: The population includes children up to 21 years old with tracheostomies. The airway center team includes providers from pediatric pulmonology, pediatric otolaryngology/head and neck surgery, and pediatric gastroenterology. Improvement initiatives included enhanced educational strategies, weekly care conferences, institutional consensus guidelines and care plans, personalized clinic schedules, and standardized intervals between airway examinations. A patient database allowed for tracking outcomes over time.

RESULTS: We initially identified 173 airway center patients including 123 with tracheostomies. The median number of new patients evaluated by the center team each year was 172. Median hospitalization after tracheostomy decreased from 37 days to 26 days for new tracheostomy patients <1 year old discharged from the hospital. A median of 24 care plans was evaluated at weekly conferences. Consensus protocol adherence increased likelihood of successful decannulation from 68% to 86% of attempts. The median interval of 8 months between airway examinations aligned with published recommendations.

CONCLUSIONS: For children with tracheostomies, our Children's Airway Center met and sustained goals of optimizing hospitalization, promoting communication, and avoiding tracheostomy complications by initiating targeted improvements in a multidisciplinary team setting. A multidisciplinary approach to management of these patients can yield measurable improvements in important outcomes.
