description: Abstract Background Hysterectomy is among the most common surgeries performed on U.S. women. For benign conditions, minimally invasive hysterectomy is recommended, whenever permitted by clinical indication and previous surgery history. No study has examined whether the use of less invasive hysterectomy spread more slowly for Black women. Methods We used the hysterectomy that occurs in outpatient settings as a proxy for minimally invasive hysterectomy. Using claims-based surgery data and census denominators, we calculated age-standardized rates of all hysterectomies in North Carolina from 2011 to 2013. Study participants were 41,899 women (64.6% non-Hispanic White, 28.3% non-Hispanic Black) who underwent hysterectomy for non-malignant indications. We fit Poisson models to determine whether changes in outpatient hysterectomy rates differed by Black-White race. We employed a difference-in-difference approach to control for racial differences in the severity of clinical indication. Further, we restricted to one state to minimize confounding from geographic differences in where Black and White women live. Results From 2011 to 2013, the overall hysterectomy rate decreased from 42.3 per 10,000 women (n = 14,648) to 37.9 per 10,000 (n = 13,241) (p < 0.0001). Most hysterectomy (67.6%) occurred in outpatient settings. The inpatient rate decreased 35.2% (p < 0.0001), to 10.3 per 10,000, while the outpatient rate increased 4.6% (p < 0.01), to 27.5 per 10,000. From 2011 to 2013, Black women’s outpatient rate increased 22% (p < 0.0001): from 25.8 per 10,000 to 31.5. In contrast, among White women, outpatient rates remained stable (p = 0.79): at 28.3 per 10,000 in 2013. Conclusions Rapid increases in outpatient hysterectomy among Black women compared to stable rates among White women indicate a race-specific catch-up phenomenon in the spread of minimally invasive hysterectomy. These results are consistent with the hypothesis that minimally invasive hysterectomy may have been adopted more slowly for Black women than their White counterparts after its introduction in the early 2000s. The persistently high rates of hysterectomy among young Black women and potentially slower adoption of minimally invasive procedures among these women highlight a potential racial disparity in women’s healthcare.

description: A computationally efficient method for solving three-dimensional, viscous, incompressible flows on unbounded domains is presented. The method formally discretizes the incompressible Navier-Stokes equations on an unbounded staggered Cartesian grid. Operations are limited to a finite computational domain through a lattice Green's function technique. This technique obtains solutions to inhomogeneous difference equations through the discrete convolution of source terms with the fundamental solutions of the discrete operators. The differential algebraic equations describing the temporal evolution of the discrete momentum equation and incompressibility constraint are numerically solved by combining an integrating factor technique for the viscous term and a half-explicit Runge-Kutta scheme for the convective term. A projection method that exploits the mimetic and commutativity properties of the discrete operators is used to efficiently solve the system of equations that arises in each stage of the time integration scheme. Linear complexity, fast computation rates, and parallel scalability are achieved using recently developed fast multipole methods for difference equations. The accuracy and physical fidelity of solutions is verified through numerical simulations of vortex rings.

description: The Earth appears non-chondritic in its abundances of refractory lithophile elements, posing a significant problem for our understanding of its formation and evolution. It has been suggested that this non-chondritic composition may be explained by collisional erosion of differentiated planetesimals of originally chondritic composition. In this work, we present N-body simulations of terrestrial planet formation that track the growth of planetary embryos from planetesimals. We simulate evolution through the runaway and oligarchic growth phases under the Grand Tack model and in the absence of giant planets. These simulations include a state-of-the-art collision model which allows multiple collision outcomes, such as accretion, erosion, and bouncing events, that enables tracking of the evolving core mass fraction of accreting planetesimals. We show that the embryos grown during this intermediate stage of planet formation exhibit a range of core mass fractions, and that with significant dynamical excitation, enough mantle can be stripped from growing embryos to account for the Earth's non-chondritic Fe/Mg ratio. We also find that there is a large diversity in the composition of remnant planetesimals, with both iron-rich and silicate-rich fragments produced via collisions.

An evaluation of the metabolic syndrome in the HyperGEN study
Creators: name: Heiss, Gerardo
Publisher: name: BioMed Central Ltd
Year: 2005

description: Abstract Background In 2001 the National Cholesterol Education Program (NCEP) provided a categorical definition for metabolic syndrome (c-MetS). We studied the extent to which two ethnic groups, Blacks and Whites were affected by c-MetS. The groups were members of the Hypertension Genetic Epidemiology Network (HyperGEN), a part of the Family Blood Pressure Program, supported by the NHLBI. Although the c-MetS definition is of special interest in particular to the clinicians, the quantitative latent traits of the metabolic syndrome (MetS) are also important in order to gain further understanding of its etiology. In this study, quantitative evaluation of the MetS latent traits (q-MetS) was based on the statistical multivariate method factor analysis (FA). Results The prevalence of the c-MetS was 34% in Blacks and 39% in Whites. c-MetS showed predominance of obesity, hypertension, and dyslipidemia. Three and four factor domains were identified through FA, classified as "Obesity," "Blood pressure," "Lipids," and "Central obesity." They explained approximately 60% of the variance in the 11 original variables. Two factors classified as "Obesity" and "Central Obesity" overlapped when FA was performed without rotation. All four factors in FA with Varimax rotation were consistent between Blacks and Whites, between genders and also after excluding type 2 diabetes (T2D) participants. Fasting insulin (INS) associated mainly with obesity and lipids factors. Conclusions MetS in the HyperGEN study has a compound phenotype with separate domains for obesity, blood pressure, and lipids. Obesity and its relationship to lipids and insulin is clearly the dominant factor in MetS. Linkage analysis on factor scores for components of MetS, in familial studies such as HyperGEN, can assist in understanding the genetic pathways for MetS and their interactions with the environment, as a first step in identifying the underlying pathophysiological causes of this syndrome.

description: A rising research challenge is running costly machine learning (ML) networks locally on resource-constrained edge devices. ML networks with large convolutional layers can easily exceed available memory, increasing latency due to excessive swapping. Previous memory reduction techniques such as pruning and quantization reduce model accuracy and often require retraining. Alternatively, distributed methods partition the convolutions into equivalent smaller sub-computations, but the implementations introduce communication costs and require a network of devices. However, a distributed partitioning approach can also be used to run in a reduced memory footprint on a single device by subdividing the network into smaller operations. This report extends prior work on distributed partitioning using tiling and fusing of convolutional layers into a memory-aware execution on a single device. Our approach extends prior fusing strategies to allow for two groups of convolutional layers that are fused and tiled independently. This approach reduces overhead via data reuse, and reduces the memory footprint further. We also propose a memory usage predictor coupled with a search algorithm to provide fusing and tiling configurations for an arbitrary set of convolutional layers. When applied to the YOLOv2 object detection network, results show that our approach can run in less than half the memory, and with a speedup of up to 2.78 under severe memory constraints. Additionally, our algorithm will return a configuration with a latency that is within 6% of the best latency measured in a manual search.

description: Abstract Background Life-threatening infections present major challenges for health systems in Malawi and the developing world because routine microbiologic culture and sensitivity testing are not performed due to lack of capacity. Use of empirical antimicrobial therapy without regular microbiologic surveillance is unable to provide adequate treatment in the face of emerging antimicrobial resistance. This study was conducted to determine antimicrobial susceptibility patterns in order to inform treatment choices and generate hospital-wide baseline data. Methods Culture and susceptibility testing was performed on various specimens from patients presenting with possible infectious diseases at Kamuzu Central Hospital, Lilongwe, Malawi. Results Between July 2006 and December 2007 3104 specimens from 2458 patients were evaluated, with 60.1% from the adult medical service. Common presentations were sepsis, meningitis, pneumonia and abscess. An etiologic agent was detected in 13% of patients. The most common organisms detected from blood cultures were Staphylococcus aureus, Escherichia coli, Salmonella species and Streptococcus pneumoniae, whereas Streptococcus pneumoniae and Cryptococcus neoformans were most frequently detected from cerebrospinal fluid. Haemophilus influenzae was rarely isolated. Resistance to commonly used antibiotics was observed in up to 80% of the isolates while antibiotics that were not commonly in use maintained susceptibility. Conclusions There is widespread resistance to almost all of the antibiotics that are empirically used in Malawi. Antibiotics that have not been widely introduced in Malawi show better laboratory performance. Choices for empirical therapy in Malawi should be revised accordingly. A microbiologic surveillance system should be established and prudent use of antimicrobials promoted to improve patient care.

Year: 2015

description: We show gapped critical environment could remarkably prevent an enhanced decay of decoherence factor and quantum correlations at the critical point, which is nontrivially different from the ones in a gapless critical environment (Quan, et.al Phys. Rev. Lett. \textbf{96}, 140604 (2006)). The quantum correlations display very fast decaying to their local minimum at the critical point while maximum decaying occurs away from this point. In particular, our results imply that collapse of decoherence factor is not indicator of a quantum phase transition of environment as opposed to what happens in a gapless criticallity. In the week coupling regime, the relaxation time, at which the quantum correlations touch rapidly local minima, shows a power-law singularity as a function of gap. Furthermore, quantum correlations decay exponentially with second power of relaxation time. Our results are important for a better understanding and characterisation of gap critical environment and its ability as entanglers in open quantum systems.

description: AbstractBackgroundThe purpose of this paper is to examine the acceptability, feasibility, reliability and validity of a new decision quality instrument that assesses the extent to which patients are informed and receive treatments that match their goals.MethodsCross-sectional mail survey of recent breast cancer survivors, providers and healthy controls and a retest survey of survivors. The decision quality instrument includes knowledge questions and a set of goals, and results in two scores: a breast cancer surgery knowledge score and a concordance score, which reflects the percentage of patients who received treatments that match their goals. Hypotheses related to acceptability, feasibility, discriminant validity, content validity, predictive validity and retest reliability of the survey instrument were examined.ResultsWe had responses from 440 eligible patients, 88 providers and 35 healthy controls. The decision quality instrument was feasible to implement in this study, with low missing data. The knowledge score had good retest reliability (intraclass correlation coefficient = 0.70) and discriminated between providers and patients (mean difference 35%, p < 0.001). The majority of providers felt that the knowledge items covered content that was essential for the decision. Five of the 6 treatment goals met targets for content validity. The five goals had moderate to strong retest reliability (0.64 to 0.87). The concordance score was 89%, indicating that a majority had treatments concordant with that predicted by their goals. Patients who had concordant treatment had similar levels of confidence and regret as those who did not.ConclusionsThe decision quality instrument met the criteria of feasibility, reliability, discriminant and content validity in this sample. Additional research to examine performance of the instrument in prospective studies and more diverse populations is needed.

title: The confluence of two rivers: the impact of social capital on the experience of work precariousness
Creators: name: Collins, H
Publisher: name: Liverpool John Moores University
Year: 2024

description: Grounded in a phenomenological paradigm of enquiry about precarious work and its impact on workers in the Northwest of Britain, this research study seeks to understand if workers can re-construct the influences of precarious work through two questions. First, can workers re-construct the (negative) influences of precarious work on their lives? If so, what enables them to do this? This research views precariousness as relational and changeable rather than fixed. and examines how reconstructing the precarious experience draws on the support of social groups in general, and social capital in particular, to support fulfilling work identities. Through a focus on the role of social capital, I challenge assumptions that precarious work has an entirely negative impact on workers and draw attention to the often-hidden acts of informal and collective resistance that can alter the precarious experience in positive ways. By bringing together social capital and precarity I demonstrate how precariousness is reproduced, making life tolerable on a day-to-day basis, yet trapping individuals in precarious roles. The body of work contributes to the literature on precariousness through four interrelated contributions: a holistic theorisation of precarity and social capital; ripple effects of precarity; phenomenon that create and reproduce precarity; and community and collective action and resistance. The conclusion examines the above contributions and suggests areas for future research. To meet the grand challenge of precariousness more insights around the antecedents and consequences of precariousness are needed; above all, what ties them together and enables the identification of moderating elements to inform the ‘happy precariat’.

Year: 2015

description: We systematically compute the annihilation rate for winos and higgsinos into the final state relevant for indirect detection experiments, gamma + X. The radiative corrections to this process receive enhancement from the large Bloch-Nordsieck-Violating Sudakov logarithm, log(2 M_chi/M_W). We resum the double logs and include single logs to fixed order using a formalism that combines nonrelativistic and soft-collinear effective field theories. For the wino case, we update an earlier exclusion adapting results of the HESS experiment. At the thermal relic mass of 3 TeV, LL' corrections result in a ~30% reduction in rate relative to LL. Nonetheless, single logs do not save the wino, and it is still excluded by an order of magnitude. Experimental cuts produce an endpoint region which, our results show, significantly effects the higgsino rate at its thermal-relic mass near 1 TeV and is deserving of further study.

description: Bosonic channels are important in practice as they form a simple model for free-space or fiber-optic communication. Here we consider a single-sender two-receiver pure-loss bosonic broadcast channel and determine the unconstrained capacity region for the distillation of bipartite entanglement and secret key between the sender and each receiver, whenever they are allowed arbitrary public classical communication. We show how the state merging protocol leads to achievable rates in this setting, giving an inner bound on the capacity region. We also evaluate an outer bound on the region by using the relative entropy of entanglement and a `reduction by teleportation' technique. The outer bounds match the inner bounds in the infinite-energy limit, thereby establishing the unconstrained capacity region for such channels. Our result could provide a useful benchmark for implementing a broadcasting of entanglement and secret key through such channels. An important open question relevant to practice is to determine the capacity region in both this setting and the single-sender single-receiver case when there is an energy constraint on the transmitter.

Publisher: name: arXiv
Year: 2015
Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)

description: We extend the recently introduced Bayesian framework `Generative Pulsar Timing Analysis' to incorporate both pulse jitter (high frequency variation in the arrival time of the pulse) and epoch to epoch stochasticity in the shape of the pulse profile. This framework allows for a full timing analysis to be performed on the folded profile data, rather than the site arrival times as is typical in most timing studies. We apply this extended framework both to simulations, and to an 11 yr, 10 cm data set for PSR J1909$-$3744. Using simulations, we show that temporal profile variation can induce timing noise in the residuals that when performing a standard timing analysis is highly covariant with the signal expected from a gravitational wave (GW) background. When working in the profile domain, these variations are de-correlated from the expected GW signal, resulting in significant improvement in the obtained upper limits. Using the PSR J1909$-$3744 data set from the Parkes Pulsar Timing Array project, we find significant evidence for systematic high-frequency profile variation resulting from non-Gaussian noise in the oldest observing system, but no evidence for either detectable pulse jitter, or low-frequency profile shape variation. Using our profile domain framework we therefore obtain upper limits on a red noise process with a spectral index of $γ= 13/3$ of $1\times10^{-15}$, consistent with previously published limits.

Publisher: name: BioMed Central
Year: 2015

description: Abstract Background Although social norms are thought to play an important role in couples’ reproductive decisions, only limited theoretical or empirical guidance exists on how the underlying process works. Using the theory of normative social behavior (TNSB), through a mixed-method design, we investigated the role played by injunctive norms and interpersonal discussion in the relationship between descriptive norms and use of modern contraceptive methods among the urban poor in India. Methods Data from a household survey (N = 11,811) were used to test the underlying theoretical propositions, and focus group interviews among men and women were then conducted to obtain more in-depth knowledge about decision-making processes related to modern contraceptive use. Results Spousal influence and interpersonal communication emerged as key factors in decision-making, waning in the later years of marriage, and they also moderated the influence of descriptive norms on behaviors. Norms around contraceptive use, which varied by parity, are rapidly changing with the country’s urbanization and increased access to health information. Conclusion Open interpersonal discussion, community norms, and perspectives are integral in enabling women and couples to use modern family planning to meet their current fertility desires and warrant sensitivity in the design of family planning policy and programs.

Tree-based model

description: This study applied tree-based machine learning methods to investigate the contributing factors to both crash frequency and injury severity in vehicle-pedestrian crash events. Vehicle and roadway characteristics, driver and pedestrian attributes, traffic controls and land use conditions, transit provision and weather conditions are used as covariates to predict pedestrian crash frequencies (by roadway segment) and injury severity levels (for pedestrians struck by vehicles on public roadways). In both cases, tree-based models offered significantly more prediction accuracy than traditional statistical models (using negative binomial and ordered probit specifications, with the same covariates). The tree-based models also offer valuable interpretability through the regression tree graph itself (with clear branching based on variable cut-points), variable importance plots (for each covariate), and partial dependence plots to help analysts understand the relationship between contributing factors and the target variable (count or severity). Average daily vehicle-miles travelled (DVMT) on each road segment, population density, segment length, census tract-level job density, distance from nearest K-12 school, transit stop density, and segment speed limits were estimated to be the top contributing factors for increasing pedestrian crash counts. DVMT has been found as the single most responsible factor for vehicle-pedestrian crashes and in a way representing pedestrian exposure to such situations. In terms of predicting injury outcomes, intoxication of the pedestrian and/or driver, higher speed limits at the site, crash location not being in the traffic way, older pedestrian, interstate highway locations, and dark and unlit conditions were predictors for more severe outcomes. Importantly, if the surrounding urban area’s population is reasonably high (over 25,000 persons), the probability of the pedestrian dying falls significantly, which supports the ‘safety in numbers’ idea, for more people available to help save the crash victims, or drivers going more slowly due to crowded conditions, closer hospitals, and so on. While few crash studies have included land use variables and local demographics, including proximity to schools, hospitals, and transit stops, population and jobs density variables appeared to add to crash counts and severity for pedestrians, though this is moderated by the 25,000-population threshold and distance variables.

description: Gamma-ray bursts (GRBs) are believed to be powered by the electromagnetic extraction of spin energy from a black hole endowed with a magnetic field supported by electric currents in a surrounding disk (Blandford & Znajek 1977). A generic feature of this mechanism is that, under certain fairly general assumptions, the energy loss rate decays exponentially. In this work, we are looking precisely for such exponential decay in the lightcurves of long duration GRBs observed with the XRT instrument on the Swift satellite. We found out that almost 30 % of XRT lightcurves show such behavior before they reach the afterglow plateau. According to Blandford & Znajek, the duration of the burst depends on the magnetic flux accumulated on the event horizon. This allows us to estimate the surface magnetic field of a possible progenitor. Our estimations are consistent with magnetic fields observed in Wolf-Rayet stars.

description: This thesis is an analysis of the relationship between conspiracy theories and religion, which is divided into three parts that build on each other. Part one provides a general intro-duction to the current state of research on conspiracy theories, examining the term and its his-tory, its characteristics, and the people who believe in them. Part two analyzes the phenome-non from a religious studies perspective and examines concrete connections, similarities, and parallels between the belief in conspiracy theories and religious belief in terms of their mo-tives and functions in satisfying epistemic, existential, and social needs. In the third part, the relevance of these connections for religious education is presented and reflected upon from a didactic point of view in order to derive possible requirements and perspectives for action in religious education, which are then presented in outline.
Protocol-driven primary care and community linkages to improve population health in rural Zambia: the Better Health Outcomes through Mentoring and Assessment (BHOMA) project
Creators: name: Stringer, Jeffrey
Publisher: name: BioMed Central Ltd

description: Abstract Introduction Zambia’s under-resourced public health system will not be able to deliver on its health-related Millennium Development Goals without a substantial acceleration in mortality reduction. Reducing mortality will depend not only upon increasing access to health care but also upon improving the quality of care that is delivered. Our project proposes to improve the quality of clinical care and to improve utilization of that care, through a targeted quality improvement (QI) intervention delivered at the facility and community level. Description of implementation The project is being carried out 42 primary health care facilities that serve a largely rural population of more than 450,000 in Zambia’s Lusaka Province. We have deployed six QI teams to implement consensus clinical protocols, forms, and systems at each site. The QI teams define new clinical quality expectations and provide tools needed to deliver on those expectations. They also monitor the care that is provided and mentor facility staff to improve care quality. We also engage community health workers to actively refer and follow up patients. Evaluation design Project implementation occurs over a period of four years in a stepped expansion to six randomly selected new facilities every three months. Three annual household surveys will determine population estimates of age-standardized mortality and under-5 mortality in each community before, during, and after implementation. Surveys will also provide measures of childhood vaccine coverage, pregnancy care utilization, and general adult health. Health facility surveys will assess coverage of primary health interventions and measures of health system effectiveness. Discussion The patient-provider interaction is an important interface where the community and the health system meet. Our project aims to reduce population mortality by substantially improving this interaction. Our success will hinge upon the ability of mentoring and continuous QI to improve clinical service delivery. It will also be critical that once the quality of services improves, increasing proportions of the population will recognize their value and begin to utilize them.

description: Omicron.BA.5.2.1毒株的分子生物学计算分析报告
 实验运用分子生物学原理，使用计算机工具，对新冠病毒原始毒株和新冠病毒最新流行毒株进行基因序列比对，从而得出相应的结论和推断，为防疫工作提供建议意见。
 （1）计算机实验证明了深圳流行的BF.15毒株（SARS-Cov-2.Omicron.BA.5.2.1的子毒株）具有突破mRNA疫苗保护的更强能力，是一种在普遍疫苗保护下进化出来的抗mRNA疫苗病毒毒株。 （2）由于S1蛋白的改变，接种mRNA疫苗的人体可能很难识别出该毒株，因此可能会出现ADE反应，或体现出致死率更高的情况。 （3）该毒株的其它变异点位并不集中，灭活疫苗依然能够提供较为有效的保护能力。 （4）该毒株并没有发声巨大的基因减材（缺失）变异，因此病毒的致病性应当与原始毒株相当，对未接种人体具有较强的肺炎致病性。 （5）在灭活疫苗的保护下，该毒株的多数感染患者依然会体现出无症状现象。
 接种疫苗的目的是保护高危人群，如果想尽快通过物理隔离的方式终止该毒株的流行，则在计算机算法当中需要保证大于50%的人群未接种疫苗，这部分人群抗病能力强，与接种疫苗的高危人群在社会当中共同生活，作为病毒探针存在，当发现症状时应立即隔离、立即防控。这种方式要好于社会中充斥着无症状患者，后者会让病毒变得难以追踪、难以扑灭，这也是朝鲜在疫情感染之后得以迅速扑灭的最根本原因。

title: Ein Rekonstruktions- und Verortungsversuch des Stürmerspruches in Q 16,16
Creators: name: Belitsch, Christoph Paul
Year: 2023

description: Die Textstelle Q 16,16 bildet eines der rätselhaftesten und abwechslungsreichsten Logien des Neuen Testaments. Neben seiner beeindruckenden inhaltlichen Fülle stechen insbesondere die Differenzen zwischen der lukanischen und matthäischen Überlieferung hervor. Diese betreffen sowohl den Kontext, in dem die Stelle eingebettet ist, als auch die Satzfolge und die Wortwahl. Unter der Annahme der Zweiquellentheorie sowie der Existenz der Logienquelle stellt sich unweigerlich die Frage, wie Q 16,16 ursprünglich überliefert wurde. Die vorliegende Diplomarbeit untersucht diese Problematik, indem sie sich an jenen Ungereimtheiten orientiert, die die Critical Edition of Q zu betreffender Textstelle vorlegt. Nachdem in einem ersten Schritt beide kanonischen Versionen kontextuell und inhaltlich analysiert werden, folgt anschließend eine Untersuchung des ursprünglichen Kontexts von Q 16,16. Da-nach werden die divergierende Satzstellung sowie die Wortdifferenzen zwischen der lukanischen und matthäischen Textstelle jeweils lexikalisch, strukturell und inhaltlich untersucht. Den Abschluss bildet eine begründende Zusammenfassung der Ergebnisse. Der Mehrwert dieser Arbeit besteht in der Entschlüsselung der ursprünglichen Intention, die der historische Jesus mit dieser Textstelle bezwecken wollte.
description: The passage Q 16,16 is one of the most enigmatic and varied logia of the New Testament. Apart from its impressive richness of content, the differences between the Lucan and Matthean traditions are particularly striking. They concern both the context in which the passage is embedded and the sequence of sentences as well as the diction. Assuming the two-source hypothesis and the existence of the Sayings source, the question inevitably arises as to how Q 16,16 was originally passed on. The present diploma thesis examines this problem by focusing on those inconsistencies that the Critical Edition of Q presents concerning this passage. After first analysing the context and content of both canonical versions, the original context of Q 16:16 is examined followed by a lexical, structural, and content analysis of the diverging sentence order and word differences between the Lucan and Matthean passage. The paper concludes with a summary of the results. The added value of this thesis consists in the deciphering of the original intention that the historical Jesus intended with this passage.

description: The central engines of disc-accreting stellar-mass black holes appear to be scaled down versions of the supermassive black holes that power active galactic nuclei. However, if the physics of accretion is universal, it should also be possible to extend this scaling to other types of accreting systems, irrespective of accretor mass, size, or type. We examine new observations, obtained with Kepler/K2 and ULTRACAM, regarding accreting white dwarfs and young stellar objects. Every object in the sample displays the same linear correlation between the brightness of the source and its amplitude of variability (rms-flux relation) and obeys the same quantitative scaling relation as stellar-mass black holes and active galactic nuclei. We also show that the most important parameter in this scaling relation is the physical size of the accreting object. This establishes the universality of accretion physics from proto-stars still in the star-forming process to the supermassive black holes at the centers of galaxies.

Creators: name: Schwarzenbacher, Florian
Year: 2023

description: In vorliegender Arbeit werden von Wind betriebene Musikinstrumente zuerst ausführlich beschrieben und in weiterer Folge hinsichtlich ihrer Klangeigenschaften untersucht. Da das Thema selten bis gar nicht in ganzheitlicher Form behandelt wurde, wird zuerst eine mögliche Übersicht über die Äolsinstrumentenfamilie nach gängigen Spezifikationen (Hornbostel-Sachs-Systematik) gegeben und in ihrer Funktion beschrieben. Um einen möglichst breiten Überblick zu verschaffen, wird anschließend auf die jeweilige Verbreitung der Instrumente eingegangen. Im zweiten Teil der Arbeit wird untersucht, welche Klangeigenschaften in der zum Teil fast überschwänglichen Rezeption der Äolsinstrumente maßgeblich beteiligt sind. Mithilfe von Signalanalysen werden die typischen Klangmerkmale von Äolsinstrumenten ermittelt sowie diejenigen Klangeigenschaften, die besonders in der Rezeption hervortreten. Im abschließenden Teil der Arbeit wird anhand eines Hörer*innenversuches der Frage nachgegangen, welche Klangeigenschaften von Äolsinstrumenten zu den beschriebenen besonderen Hörerlebnissen führen.
