description: The processes leading to the birth of high-mass stars are poorly understood. We characterise here a sample of 430 massive clumps from the ATLASGAL survey, which are representative of different evolutionary stages. To establish a census of molecular tracers of their evolution we performed an unbiased spectral line survey covering the 3-mm atmospheric window between 84-117 GHz with the IRAM 30m. A smaller sample of 128 clumps has been observed in the SiO (5-4) transition with the APEX telescope to complement the SiO (2-1) line and probe the excitation conditions of the emitting gas, which is the main focus of the current study. We report a high detection rate of >75% of the SiO (2-1) line and a >90% detection rate from the dedicated follow-ups in the (5-4) transition. The SiO (2-1) line with broad line profiles and high detection rates, is a powerful probe of star formation activity, while the ubiquitous detection of SiO in all evolutionary stages suggests a continuous star formation process in massive clumps. We find a large fraction of infrared-quiet clumps to exhibit SiO emission, the majority of them only showing a low-velocity component (FWHM~5-6 km/s) centred at the rest velocity of the clump. In the current picture, where this is attributed to low-velocity shocks from cloud-cloud collisions, this can be used to pinpoint the youngest, thus, likely prestellar massive structures. Based on the line ratio of the (5-4) to the (2-1) line, our study reveals a trend of changing excitation conditions that lead to brighter emission in the (5-4) line towards more evolved sources. Our analysis delivers a more robust estimate of SiO column density and abundance than previous studies and questions the decrease of jet activity in massive clumps as a function of age.

description: Without measurement errors in predictors, discontinuity of a nonparametric regression function at unknown locations could be estimated using a number of existing approaches. However, it becomes a challenging problem when the predictors contain measurement errors. In this paper, an error-in-variables jump point estimator is suggested for a nonparametric generalized error-in-variables regression model. A major feature of our method is that it does not impose any parametric distribution on the measurement error. Its performance is evaluated by both numerical studies and theoretical justifications. The method is applied to studying the impact of Medicare Levy Surcharge on the private health insurance take-up rate in Australia.

Contemporary Klezmer: Music, Identity, and Meaning
Creators: name: Parshall, Joshua
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Klezmer, the traditional instrumental music of Eastern European Jews, developed as the accompaniment to weddings and other communal celebrations. After an initial blossoming in the early-twentieth century United States, the style lost prominence due to a variety of historical, political, and social factors. Since the 1970s, however, Jewish and non-Jewish musicians have revived and transformed older styles of playing, both in North America and across the world. This thesis examines American discourses surrounding Jewish identity and traditional music, to demonstrate how earlier conceptions of authenticity, hipness, dissent, and difference continue to shape musicians' and fans' interpretations of klezmer music. Drawing from ethnographic research, historical accounts, and theoretical work in folklore, cultural studies, and performance studies, the thesis emphasizes klezmer's role as an active site for the collective and individual negotiation and performance of Jewish identity in the late twentieth and early twenty-first centuries.

Subjects: subject: Medicine and Health Sciences

description: The delivery of hospital care is dramatically changing in the face of new technologies, coupled with increasing social and economic burdens of ageing populations and prevalence of chronic disease.[1, 2] To address the growing challenges, hospitals and governments are experimenting with more cost-effective care alternatives, delivered outside hospitals walls;[3] prioritising greater consumer engagement;[1] and investing in digitised care services.[4] Some hospitals have introduced emerging technologies (e.g., robotics, artificial intelligence (AI), big data analytics) into hospital workflows, to deliver care more seamlessly and continually improve their services.[5-7] This study will build upon a grey literature search that identified seven innovative models of healthcare delivery. As we are interested in the utility of these models, this review will evaluate the evidence-based support for these innovative models of care in addressing high prevalence, priority conditions (chronic and acute), which were derived from local demographic data. This search will be undertaken across medical, nursing, and psychological databases to extract articles detailing clinical methods, healthcare delivery, and patient outcomes. Moreover, as we are interested in innovative methods, we will be limiting our search to only include research published within the last five years.

description: We introduce hmmSeq, a model-based hierarchical Bayesian technique for detecting differentially expressed genes from RNA-seq data. Our novel hmmSeq methodology uses hidden Markov models to account for potential co-expression of neighboring genes. In addition, hmmSeq employs an integrated approach to studies with technical or biological replicates, automatically adjusting for any extra-Poisson variability. Moreover, for cases when paired data are available, hmmSeq includes a paired structure between treatments that incoporates subject-specific effects. To perform parameter estimation for the hmmSeq model, we develop an efficient Markov chain Monte Carlo algorithm. Further, we develop a procedure for detection of differentially expressed genes that automatically controls false discovery rate. A simulation study shows that the hmmSeq methodology performs better than competitors in terms of receiver operating characteristic curves. Finally, the analyses of three publicly available RNA-seq data sets demonstrate the power and flexibility of the hmmSeq methodology. An R package implementing the hmmSeq framework will be submitted to CRAN upon publication of the manuscript.

description: We explore the impact of cosmic rays (CRs) on cosmological adaptive-mesh refinement simulations of a forming 10^12 Msolar halo, focusing on the circumgalactic medium (CGM), and its resulting low-redshift structure and composition. In contrast to a run with star formation and energetic feedback but no CRs, the CR-inclusive runs feature a CGM substantially enriched with CRs and with metals to roughly 0.1 Zsolar, thanks to robust, persistent outflows from the disk. The CR-inclusive CGMs also feature more diffuse gas at lower temperatures, down to 10^4 K, than the non-CR run, with diffuse material often receiving a majority of its pressure support from the CR proton fluid. We compare to recent observations of the CGM of L ~ L* galaxies at low redshift, including UV absorption lines within background quasar spectra. The combination of metal-enriched, CR-driven winds and large swaths of CR pressure-supported, cooler diffuse gas leads to a CGM that provides a better match to data from COS-Halos (for HI, SiIV, CIII and OVI) than the non-CR run. We also compare our models to recent, preliminary observations of diffuse gamma-ray emission in local group halos. For our lower CR-diffusion runs with kappa_CR in the range 0.3 to 1 x 10^28 cm^2/s, the CR enriched CGM produces an inconsistently high level of gamma emission. But the model with a relatively high kappa_CR = 3 x 10^28 cm^2/s provided a gamma-ray luminosity consistent with the extra-galactic gamma-ray background observed by FERMI and roughly consistent with preliminary measures of the emission from M31's CGM.

description: Bernard et al. (2015) study an optimal insurance design problem where an individual's preference is of the rank-dependent utility (RDU) type, and show that in general an optimal contract covers both large and small losses. However, their contracts suffer from a problem of moral hazard for paying more compensation for a smaller loss. This paper addresses this setback by exogenously imposing the constraint that both the indemnity function and the insured's retention function be increasing with respect to the loss. We characterize the optimal solutions via calculus of variations, and then apply the result to obtain explicitly expressed contracts for problems with Yaari's dual criterion and general RDU. Finally, we use a numerical example to compare the results between ours and that of Bernard et al. (2015).

description: Background: There is general agreement that implant supported prostheses offer better masticatory function than traditional prostheses that are not supported by teeth or implants. However, solid evidence is lacking to fully support this, and contrary findings are mentioned in the literature. Aim: To characterize differences in chewing and neuromuscular control characteristics of patients with upper and lower natural teeth, upper full dentures and lower natural teeth, upper and lower full dentures, upper full dentures and lower implant-supported overdentures, upper full dentures and lower implant supported fixed prostheses. Materials and methods: Chewing function is evaluated subjectively (questionnaires) and objectively (electromyographic measurements), while subjects are chewing agar based model foods with 4 different consistencies. Conclusions: Electromyographic methods using i) engineered test foods with controlled physical properties and ii) rigorous analytical techniques can detect and characterize meaningful differences among human subjects who differ in dental status and prosthodontic treatments.

description: Young, intermediate-mass stars are experiencing renewed interest as targets for direct-imaging planet searches. However, these types of stars are part of multiple systems more often than not. Close stellar companions affect the formation and orbital evolution of any planets, and the properties of the companions can help constrain the binary formation mechanism. Unfortunately, close companions are difficult and expensive to detect with imaging techniques. In this paper, we describe the direct spectral detection method wherein a high-resolution spectrum of the primary is cross-correlated against a template for a companion star. Variants of this method have previously been used to search for stellar, brown dwarf, and even planetary companions. We show that the direct spectral detection method can detect companions as late as M-type orbiting A0 or earlier primary stars in a single epoch on small-aperture telescopes. In addition to estimating the detection limits, we determine the sources of uncertainty in characterizing the companion temperature, and find that large systematic biases can exist. After calibrating the systematic biases with synthetic binary star observations, we apply the method to a sample of 34 known binary systems with an A- or B-type primary star. We detect nine total companions, including four of the five known companions with literature temperatures between $4000$ K $ < T < 6000$ K, the temperature range for which our method is optimized. We additionally characterize the companion for the first time in two previously single-lined binary systems and one binary identified with speckle interferometry. This method provides an inexpensive way to use small-aperture telescopes to detect binary companions with moderate mass-ratios, and is competitive with high-resolution imaging techniques inside $\sim 100-200$ mas.

description: In this paper, we theoretically investigate how laser fields change the nature of topological Kondo insulators(TKIs). By employing a prototypical model of TKIs, we treat the effect of the laser fields with Floquet theory, which gives effective description under high frequency laser fields. We derive the effective model of TKIs under the laser irradiation and discuss its topological properties. We demonstrate a possible realization of Floquet Chern insulators specified by various values of Chern number and reveal how the topological phase changes with increasing the laser light intensity. Furthermore, it is shown that Floquet Weyl semimetals, which have some pairs of Weyl nodes protected topologically, can emerge in the three-dimensional case. We explain how the Weyl nodes are created with varying the strength of the laser field.

description: This study examines seventy-one occupational epitaphs of urban freedwomen from the western half of the Roman Empire between the first century B.C. and the third century A.D. An evaluation of the occupational epitaphs of freedwomen preserved in the Corpus Inscriptionum Latinarum (CIL) reveals the breadth of jobs freedwomen held in the urban Roman economy. The choice of commemorating these women's occupations also suggests that pride was taken in their work. A study of the epitaphs in which freedwomen were commemorated with men (just over half of the corpus) suggests that it is the occupation of the freedwomen rather than any social relationship that carries force which conveys their identity. These occupational epitaphs demonstrate that one avenue of commemoration which freedwomen or their relatives elected to employ was memorializing their work as a symbol of the pride in their change of status from slave to freedwoman.

description: Randomized Controlled Trials (RCTs) are considered the gold standard to evaluate the safety and efficacy of treatments and interventions in clinical research (1). Conducting high-quality RCTs is challenging, time consuming and resource intensive (2–4). Consequently, tens of billions of dollars of public and private money are invested into this sector every year (5). Furthermore, RCT costs are rising in response to escalating trial complexity, stricter regulation, and increasing administrative burden (2,6–9). Academic investigators usually depend on scarce financial resources, thus efforts to improve the cost-effectiveness of RCTs are urgently needed. Current literature, however, lacks systematically collected empirical data on detailed resource use and costs of investigator-initiated RCTs. The aim of this study is to generate a database of detailed empirical resource use and cost data from 180 investigator-initiated RCTs in Switzerland, Germany, Canada, and the United Kingdom (UK).

description: We report on the discovery of a z=1.58 mature cluster around the high-redshift radio galaxy 7C1753+6311, first identified in the Clusters Around Radio-Loud AGN survey. Two-thirds of the excess galaxies within the central 1Mpc lie on a red sequence with a colour that is consistent with an average formation redshift of zf~3. We show that 80+/-6% of the red sequence galaxies in the cluster core are quiescent, while the remaining 20% are red due to dusty star formation. We demonstrate that the cluster has an enhanced quiescent galaxy fraction that is three times that of the control field. We also show that this enhancement is mass dependent: 91+/-9% of the M* >10^{10.5}Msun cluster galaxies are quiescent, compared to only 36+/-2% of field galaxies, whereas the fraction of quiescent galaxies with lower masses is the same in the cluster and field environments. The presence of a dense core and a well-formed, quiescent red sequence suggest that this is a mature cluster. This means that distant radio galaxies do not solely reside in young, uncollapsed protoclusters, rather they can be found in clusters in a wide range of evolutionary states.

description: The United States has the highest healthcare costs amongst developed nations with approximately 25% being considered waste. Physicians play a significant role in this waste when they order low-value tests, imaging, and interventions. Previous studies involving resident education have demonstrated the ability to decrease inappropriate laboratory test ordering without negatively impacting the quality of care. Translating these findings to undergraduate medical education, we explored the feasibility of integrating value-based care education into existing platforms in Oregon Health and Science University’s (OHSU) medical school curricula. We hypothesized that curricular changes could improve medical student knowledge, attitudes, and competency with high-value cost-conscious medical care (HVCCC).

description: We focus on the biological problem of tracking organelles as they move through cells. In the past, most intracellular movements were recorded manually, however, the results are too incomplete to capture the full complexity of organelle motions. An automated tracking algorithm promises to provide a complete analysis of noisy microscopy data. In this paper, we adopt statistical techniques from a Bayesian random set point of view. Instead of considering each individual organelle, we examine a random set whose members are the organelle states and we establish a Bayesian filtering algorithm involving such set states. The propagated multi-object densities are approximated using a Gaussian mixture scheme. Our algorithm is applied to synthetic and experimental data.

Protocol Registration: Reviewing Aroma - A Scoping Review of Aromatherapy in Gynecological Cancer Care
Creators: name: Czakert, Judith

Year: 2022
Subjects: subject: Alternative and Complementary Medicine
subject: Integrative Medicine
subject: Medicine and Health Sciences
subject: Medical Specialties
subject: Oncology

description: Despite a high potential of aromatherapy for women with gynaecological-oncological diseases, no recent attempts have been made to summarize and integrate the empirical research activities focusing specifically on this target group. A review about character, features and content of empirical research activities on aromatherapy for this patient group is both: overdue and promising. Hence, the objective of this scoping review is to provide an overview of previous empirical research on aromatherapy in gynecological oncology patients. More specifically, it is intended to describe topic-related research gaps, challenges and specifics in order to be able to consider them in future research and in practical application. For this purpose, a literature-based systematic scoping review is going to be conducted, based on the extension of the PRISMA statement for scoping reviews (PRISMA-ScR) by Tricco and Peters and colleagues (Tricco et al., 2018, Peters et al., 2015).

In vivo force decay of NiTi closed coil springs
Creators: name: Cox, Crystal R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Nickel-titanium(NiTi) closed coil springs are purported to deliver constant forces over extended activation ranges. In vivo studies supporting this claim are limited. Objectives: Evaluate force decay properties of NiTi coil springs after clinical use. Methods: Force-deflection curves for 30 NiTi coil springs(used intra-orally) and 15 laboratory springs were generated pre- and post-retrieval to evaluate force loss following 4, 8, or 12 weeks of use. In vivo and in vitro data were compared to evaluate effect of the oral environment on force properties. Results: Springs showed force decrease (~12%,p<0.01) following 4 weeks of clinical use, with a further significant decrease (~7%,p=0.03) from 4-8 weeks; force levels remained steady thereafter. Space closed at an average rate of 0.91mm/month. In vivo and in vitro force loss data were not statistically different. Conclusions: NiTi closed coil springs do not deliver constant forces when used intra-orally, but still allow for space closure rates of ~1mm/month.

The Ladies of Roubaud (c. 1245–1414): Vision, Faith and Identity in a Provençal Beguine Community
Creators: name: LORD, JENNIFER ANN
Publisher: name: Monash University
Year: 2023
Subjects: History of religion
Gender history
European history (excl. British, classical Greek and Roman)

description: The 'beguine ladies' of Roubaud (c. 1245–1414) were a community of religious laywomen in Provence allied to the local Franciscans. The thesis argues that they resisted institutional Church pressure on religious women to enter cloistered convents, instead offering women inspired by the example of Francis of Assisi an open, less restrictive religious life. The thesis reconstructs their history from the saint’s Life of their foundress, Douceline of Digne (1215–1274), and from documents left by the women.
Atomic Chemistry in Turbulent Astrophysical Media II: Effect of the Redshift Zero Metagalactic Background
Creators: name: Gray, William J

Publisher: name: arXiv
Year: 2015
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: We carry out direct numerical simulations of turbulent astrophysical media exposed to the redshift zero metagalactic background. The simulations assume solar composition and explicitly track ionizations, recombinations, and ion-by-ion radiative cooling for hydrogen, helium, carbon, nitrogen, oxygen, neon, sodium, magnesium, silicon, sulfur, calcium, and iron. Each run reaches a global steady state that not only depends on the ionization parameter, $U,$ and mass-weighted average temperature, $T_{\rm MW},$ but also on the the one-dimensional turbulent velocity dispersion, \soned. We carry out runs that span a grid of models with $U$ ranging from 0 to 10$^{-1}$ and \soned\ ranging from 3.5 to 58 km s$^{-1}$, and we vary the product of the mean density and the driving scale of the turbulence, $nL,$ which determines the average temperature of the medium, from $nL =10^{16}$ to $nL =10^{20}$ cm$^{-2}$. The turbulent Mach numbers of our simulations vary from $M \approx 0.5$ for the lowest velocity dispersions cases to $M \approx 20$ for the largest velocity dispersion cases. When $M \lesssim1,$ turbulent effects are minimal, and the species abundances are reasonably described as those of a uniform photoionized medium at a fixed temperature. On the other hand, when $M \gtrsim 1,$ dynamical simulations such as the ones carried out here are required to accurately predict the species abundances. We gather our results into a set of tables, to allow future redshift zero studies of the intergalactic medium to account for turbulent effects.
