description: The current study seeks to examine how student endorsement of stereotypes, whether racial, gendered, and/or intersectional stereotypes, impact how students evaluate their teaching assistants and how these stereotypes impact the experiences of teaching assistants who possess marginalized identities. Specifically, this study focuses on evaluations of Black compared to White individuals, women in comparison to men, and comparisons between the four intersectional identities. The researchers seek to identify how stereotype endorsement impact evaluations of TAs of marginalized identities while showcasing that TAs can have the same instruction yet be evaluated differently based on the biases students taking the course hold. Most importantly, this study seeks to showcase that Black women may be more at risk of experiencing these biases in comparison to their prototypical counterparts.

description: The ages of the most common stars - low-mass (cool) stars like the Sun, and smaller - are difficult to derive because traditional dating methods use stellar properties that either change little as the stars age or are hard to measure. The rotation rates of all cool stars decrease substantially with time as the stars steadily lose their angular momenta. If properly calibrated, rotation therefore can act as a reliable determinant of their ages based on the method of gyrochronology. To calibrate gyrochronology, the relationship between rotation period and age must be determined for cool stars of different masses, which is best accomplished with rotation period measurements for stars in clusters with well-known ages. Hitherto, such measurements have been possible only in clusters with ages of less than about one billion years, and gyrochronology ages for older stars have been inferred from model predictions. Here we report rotation period measurements for 30 cool stars in the 2.5-billion-year-old cluster NGC 6819. The periods reveal a well-defined relationship between rotation period and stellar mass at the cluster age, suggesting that ages with a precision of order 10 per cent can be derived for large numbers of cool Galactic field stars.

Training

description: This deliverable describes the Trans National Access (TNA) activities carried out during the ARIADNEplus project within Work Package 11 (WP11) by CNR and describes the results achieved by this work package. CNR were responsible for the delivery of TNA entitled “Visual Media for the Documentation of Fieldwork and Artefacts” at their premises in Pisa, Italy. The first TNA call went out in 2019 and only three person were able to complete their in-house training before the pandemic restrictions stopped travel. No further activities could be undertaken until 2021 when it was decided to organise the TNA as four Summer Schools and all previously accepted applicants were offered (and took up) places on the week-long courses. All candidates had to send in application forms describing their projects and how these would benefit from the use of Visual Media. One of three independent reviewers each evaluated the applications and awarded a mark and recommendation to ensure the quality and relevance of the training for the applicants. The WP11 training was designed to support researchers who wish to use visual media for the management of activities in the field and/or for the study of objects for their specific project. Participants had access to equipment and facilities in the CNR-ISTI (VCL) laboratory with technical support from the tutors, which provided the opportunity to work with state-of-the-art cameras and scanners, post-processing packages and advanced viewing platforms. Each student had the possibility to learn about creating visual media datasets for the documentation of artefacts and archaeological finds, taking in account preservation and sharing of datasets, guidance and advice were tailored to each individual project. The training concluded with a review of the results achieved and further input from local experts on continuation of the work once back home. In total, all six applicants were offered places of which five were able to attend (one dropped out due to a serious family situation). Each student was asked to complete feedback forms after completing their TNA placements. The quality of the students and their projects as well as the training provided is reflected in the feedback. All the students were highly appreciative of the Summer School and what they had learned and from the comments, it is apparent that the Summer School catered very well to the individual requirements of each student. In terms of numbers, the attendance was lower than expected (six offers for 10 places) and if the Summer School had been able to run a year or two earlier as well, it is highly likely that the target would have been met. However, it is evident that the TNA was very well received, meeting the expectations and requirements of the students so that the lower numbers actually was a benefit for those who were able to attend.

description: In realizing practical non-trivial topological electronic phases stable structures need to be determined first. Tin and lead do stabilize an optimal two-dimensional high-buckled phase --a hexagonal-close packed bilayer structure with nine-fold atomic coordination-- and they do not stabilize topological fullerenes, as demonstrated by energetics, phonon dispersion curves, and the structural optimization of finite-size samples. The high-buckled phases are metallic due to their high atomic coordination. The optimal structure of fluorinated tin lacks three-fold symmetry and it stabilizes small samples too. It develops two oblate conical valleys on the first Brillouin zone coupling valley, sublattice, and spin degrees of freedom with a novel $τ_zσ_xs_x$ term, thus making it a new 2D platform for valleytronics.

description: Background: The European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 Physical Functioning subscale is a widely used patient-reported outcome measure that quantifies cancer patients' physical functioning. Strong floor/ceiling effects can affect a scale's sensitivity to change. The aim of this study was to characterize floor/ceiling effects of the physical functioning domain in patients with advanced/metastatic breast cancer enrolled in commercial clinical trials and a community-based trial. Methods: The clinical trial cohort comprised patients from 5 registrational trials submitted to the Food and Drug Administration for review (2010-2017). The community cohort comprised a subgroup of patients from the Alliance Patient Reported Outcomes to Enhance Cancer Treatment (PRO-TECT) trial. The distribution of patient responses to Physical Functioning items and the summed score were assessed at the baseline and 3-month follow-up for both cohorts. Descriptive statistics were used to determine floor/ceiling effects at the item and scale levels. Results: The clinical trial cohort and the community cohort consisted of 2407 and 178 patients, respectively. Twenty-four percent or more of the respondents reported “not at all” for having trouble/needing help with each Physical Functioning item across both cohorts and measurement time points. Fourteen to twenty percent of the patients scored perfectly (100 of 100) on the Physical Functioning subscale summary measure (where higher scores indicated better physical functioning) across both cohorts and time points. Conclusions: Minor floor effects and notable ceiling effects were found at the item and scale levels of the Physical Functioning subscale, regardless of cohort, and this creates some uncertainty about its ability to detect changes in physical functioning among high-functioning patients. Investigators may consider adding additional high-functioning items from the EORTC's item library to more accurately describe the impact of anticancer treatment on patients' physical functioning.

description: This qualitative study explored the Doctor's perspectives, experiences and practices in relation to breaking bad news (BBN) to patients or relatives/attendants. The bad news is defined as one which is pertaining to a situation where there is a feeling of no hope, a threat to a person's mental or physical well-being, a risk of upsetting an established lifestyle or where a message is given which conveys to individual fewer choices in his or her life. In this phenomenal qualitative approach, we collected data from a tertiary care hospital by focus group discussion. The sample size was 30 doctors with 1-8 years of working experience in the hospital. For less experienced doctors it was difficult to break the bad news but with experience, they found it relatively easier. Doctors explored that it was difficult to break news about young patients and children as well as too uneducated people. It is difficult to break due to an inappropriate setting and strategy. It's not a divine force; we can learn it by improving our communication skills. This study provides an insight into a range of different strategies and coping skills using by the doctors (junior and seniors both) in relation to BBN. The results reinforce and refine the imperative for further training to address the impact of BBN from the doctor's perspective if the performance of this critical task is to be improved.

description: Nonribosomal peptide synthetases (NRPSs) are typically multimodular enzymes that assemble amino acids or carboxylic acids into complex natural products. Here, we characterize a monomodular NRPS, PvfC, encoded by the Pseudomonas virulence factor (pvf) gene cluster that is essential for virulence and signaling in different bacterial species. PvfC exhibits a unique adenylation-thiolation-reductase (ATR) domain architecture that is understudied in bacteria. We show that the activity of PvfC is essential in the production of seven leucine-derived heterocyclic natural products, including two pyrazines, a pyrazinone, and a rare disubstituted imidazole, as well as three pyrazine N-oxides that require an additional N-oxygenation step. Mechanistic studies reveal that PvfC, without a canonical peptide-forming domain, makes a dipeptide aldehyde intermediate en route to both the pyrazinone and imidazole. Our work identifies a novel biosynthetic route for the production of pyrazinones, an emerging class of signaling molecules and virulence factors. Our discovery also showcases the ability of monomodular NRPSs to generate amino acid- and dipeptide-aldehydes that lead to diverse natural products. The diversity-prone biosynthesis by the pvf-encoded enzymes sets the stage for further understanding the functions of pvf in bacterial cell-to-cell signaling.

description: In-plant curing costs may mean the difference between profit and loss for many hide processing firms. Efficiency in hide curing also has an important impact on the ability of the American hide and leather industries to compete effectively in domestic and foreign markets. Accordingly, this study was conducted to provide hide processors with guidelines for lowering their marketing costs and increasing their processing efficiency. Data were obtained on the costs, labor, and equipment requirements from 21 hide firms of various sizes curing hides by the following methods: (1) pack salting, (2) agitated brine curing, (3) brine curing of fleshed hides by the pit method, and (4) agitated brine curing of fleshed hides.
Parametric instability in warped astrophysical discs: growth, saturation and feedback

description: Attempts to understand the dynamics of warped astrophysical discs have garnered significant attention, largely motivated by the growing catalogue of observed distorted systems. Previous studies have shown that the evolution of the warp is crucially regulated by the internal flow fields established by the undulating geometry. These are typically modelled as laminar horizontal, shearing flows which oscillate back and forth at approximately the orbital frequency. However this shearing motion is known to be susceptible to a hydrodynamic, parametric instability of inertial waves which might modify the warped dynamics. Whilst the linear growth phase is well understood, the subsequent nonlinear saturation combined with the self-consistent feedback onto the warp has not been studied. In this work, we implement a novel numerical setup using the recent ring model framework of Fairbairn and Ogilvie, within the Lagrangian code GIZMO. We formally identify several locally growing modes in the simulation, as predicted by a three-mode coupling analysis of the instability, and find decent agreement with the theoretical growth rates. We understand the saturation mechanism as a wave breaking process which suppresses the growth of shorter wavelength parametric couplings first, whilst allowing the longest mode to dominate the final quasi-steady, wavelike turbulence. The Reynolds stresses, transporting energy from the warp to the small scales, can be effectively modelled using a time-dependent, anisotropic viscous alpha model which closely captures the amplitude and phase evolution of the warp. Consequently, this model might help inform future global studies which are commonplace but typically don't resolve the parametric instability.

description: This article explores the evolution of pop art from its origins in the mid-20th century to its relevance in contemporary art. Pop art emerged as a response to the consumerist culture and mass media imagery of the post-World War II era. It challenged traditional notions of high art by incorporating elements of popular culture and everyday objects into artworks. The article discusses the historical context of pop art and its themes of consumerism, celebrity culture, and the intersection of art and popular media. It also examines how contemporary pop artists continue to engage with social and political issues, incorporating new techniques, materials, and cultural references. The article concludes by highlighting the ongoing significance of pop art as a dynamic and impactful artistic movement.

description: The IceCube Neutrino Observatory has the invaluable capability of continuously monitoring the whole sky. This has affirmed the role of IceCube as a sentinel, providing real-time alerts to the astrophysical community on the detection of high-energy neutrinos and neutrino flares from a variety of astrophysical sources. As a response to the IceCube alerts, different observatories can join forces in the multi-messenger observation of transient events and the characterisation of their astrophysical sources. The 2017 breakthrough identification of blazar TXS 0506+056 as the source of high-energy neutrinos and UHE gamma rays was proof of this strategy. The Gamma-ray Follow-Up (GFU) is the IceCube program for identifying high-energy muon neutrino single events, as well as outstanding neutrino flares from relevant sources and the whole wide universe. While the identification of single high-energy neutrinos is shared on public alert distribution networks, partner Imaging Air Cherenkov Telescopes are sent low-latency alerts following the detection of neutrino flares, for which they have dedicated follow-up programs. I will present an overview of the GFU platform together with new results from the analysis of recorded neutrino flares, after a dozen years of GFU operation and hundreds of alerts being sent.

description: The light curve of 1SWASP J140747.93-394542.6, a $\sim$16 Myr old star in the Sco-Cen OB association, underwent a complex series of deep eclipses that lasted 56 days, centered on April 2007. This light curve is interpreted as the transit of a giant ring system that is filling up a fraction of the Hill sphere of an unseen secondary companion, J1407b. We fit the light curve with a model of an azimuthally symmetric ring system, including spatial scales down to the temporal limit set by the star's diameter and relative velocity. The best ring model has 37 rings and extends out to a radius of 0.6 AU (90 million km), and the rings have an estimated total mass on the order of $100 M_{Moon}$. The ring system has one clearly defined gap at 0.4 AU (61 million km), which we hypothesize is being cleared out by a $< 0.8 M_{\oplus}$ exosatellite orbiting around J1407b. This eclipse and model implies that we are seeing a circumplanetary disk undergoing a dynamic transition to an exosatellite-sculpted ring structure and is one of the first seen outside our Solar system.

description: The ultra-luminous infrared galaxy Arp2 20 is a late-stage merger with several tidal structures in the outskirts and two very compact, dusty nuclei that show evidence for extreme star formation and host at least one AGN. New and archival high-resolution images taken by the Hubble Space Telescope provide a state-of-the-art view of the structures, dust, and stellar clusters in Arp 220. We find that ~90% of the Halpha emission arises from a shock-ionized bubble emanating from the AGN in the western nucleus, while the nuclear disks dominate the Pbeta emission. Four very young (~3-6 Myr) but lower mass (< 10^4 Msun) clusters are detected in Halpha within a few arcsec of the nuclei, but produce less than 1% of the line emission. We see little evidence for a population of massive clusters younger than 100Myr anywhere in Arp 220. From the masses and ages of the detected clusters, we find that star formation took place more-or-less continuously starting ~few Gyr ago with a rate between ~3-12 Msun/yr. Approximately 100Myr ago, star formation shut off suddenly everywhere, except in the nuclear disks. A very recent flicker of weak star formation produced the four young, low-mass clusters, while the rest of the galaxy appears to have remained in a post-starburst state. Cluster ages indicate that the tidal structures on the west side of the galaxy are older than those on the east side, but all appear to pre-date the shutoff of star formation. Arp 220 has many of the characteristics expected of a 'Shocked Post-Starburst Galaxy' or SPOG, since most of the system has been in a post-starburst state for the past ~100Myr and the detected Halpha emission arises from shocked rather than photo-ionized gas.

description: Despite the success of galaxy-scale strong gravitational lens studies with Hubble-quality imaging, the number of well-studied strong lenses remains small. As a result, robust comparisons of the lens models to theoretical predictions are difficult. This motivates our application of automated Bayesian lens modeling methods to observations from public data releases of overlapping large ground-based imaging and spectroscopic surveys: Kilo-Degree Survey (KiDS) and Galaxy and Mass Assembly (GAMA), respectively. We use the open-source lens modeling software PyAutoLens to perform our analysis. We demonstrate the feasibility of strong lens modeling with large-survey data at lower resolution as a complementary avenue to studies that utilize more time-consuming and expensive observations of individual lenses at higher resolution. We discuss advantages and challenges, with special consideration given to determining background source redshifts from single-aperture spectra and to disentangling foreground lens and background source light. High uncertainties in the best-fit parameters for the models due to the limits of optical resolution in ground-based observatories and the small sample size can be improved with future study. We give broadly applicable recommendations for future efforts, and with proper application this approach could yield measurements in the quantities needed for robust statistical inference.

New low-mass members of the Octans stellar association and an updated 30-40 Myr lithium age

description: The Octans association is one of several young stellar moving groups recently discovered in the Solar neighbourhood, and hence a valuable laboratory for studies of stellar, circumstellar disc and planetary evolution. However, a lack of low-mass members or any members with trigonometric parallaxes means the age, distance and space motion of the group are poorly constrained. To better determine its membership and age, we present the first spectroscopic survey for new K and M-type Octans members, resulting in the discovery of 29 UV-bright K5-M4 stars with kinematics, photometry and distances consistent with existing members. Nine new members possess strong Li I absorption, which allow us to estimate a lithium age of 30-40 Myr, similar to that of the Tucana-Horologium association and bracketed by the firm lithium depletion boundary ages of the Beta Pictoris (20 Myr) and Argus/IC 2391 (50 Myr) associations. Several stars also show hints in our medium-resolution spectra of fast rotation or spectroscopic binarity. More so than other nearby associations, Octans is much larger than its age and internal velocity dispersion imply. It may be the dispersing remnant of a sparse, extended structure which includes some younger members of the foreground Octans-Near association recently proposed by Zuckerman and collaborators.

description: The development of auditory skills is a precursor to the development of spoken language. The purpose of this study was to investigate the impact of age at cochlear implant (CI) activation on the trajectory of auditory skill acquisition in children with congenital deafness. A retrospective review of Functional Listening Index (FLI)1 scores for children who received a CI before 3 years of age showed that children activated early, specifically before 9 months of age, demonstrated a steeper trajectory of auditory skill development and achieved the number of auditory skills expected of children with normal hearing by 2 years of age.

description: We study point-like explosive events (EE), characterized by emission in the far wings of spectral lines, in a quiet region near the South Pole, using Interface Region Imaging Spectrograph (IRIS) spectra at two slit positions, slit-jaw (SJ) observations and Atmospheric Imaging Assembly (AIA) images. The events were best visible in SiIV spectra; they were weak in SJs, occasionally visible in 1600 A and 304 A AIA images, and invisible in higher temperature AIA images. We identified EEs from position--time images in the far wings of the SiIV lines and measured their distance from the limb. A Gaussian model of the height distribution showed that EEs occur in a narrow (0.9") height range, centered at 3.2" above the continuum limb at 2832.0 A. On the disk, we found that they occur in network boundaries. Further, we studied the line profiles of two bright EEs above the limb and one on the disk. We found that what appears as broad-band emission, is actually a superposition of 2--3 narrow-band Gaussian components with well-separated line profiles, indicating that material is expelled towards and/or away from the observer in discrete episodes in time and in space. The expelled plasma accelerates quickly, reaching line-of-sight (LOS) velocities up to 90 km/s. Overall, the motion was practically along the LOS, as the velocity on the plane of sky was small. In some cases tilted spectra were observed that could be interpreted in terms of rotating motions of up to 30 km/s. We did not find any strong absorption features in the wing of the SiIV lines, although in one case a very weak absorption feature was detected. No motions, indicative of jets, were detected in SJ or AIA images. Reconnection in an asymmetric magnetic-field geometry, in the middle or near the top of small loops is a plausible explanation of their observational characteristics.

description: Despite the growing body of literature citing the public health and economic concerns of untreated hearing loss, hearing healthcare still faces disparities in access1,2. The issues of accessibility in the general healthcare system are widely recognized by clinicians and researchers; however, there is limited research on this topic specific to cochlear implantation. Previous research demonstrates that patient characteristics (e.g., socioeconomic status and place of residence) and provider characteristics (e.g., availability) impact access to hearing healthcare3-5. The intersectional and compounding nature of these variables make understanding individual barriers to care incredibly complex. As these studies demonstrate, disparities in access to care are particularly prevalent among patients with low socioeconomic status (SES) and those who reside in rural areas that are further from clinic sites4. It is likely that these disparities also influence access to the audiological and medical evaluations for cochlear implantation candidacy evaluation and associated postoperative care. To ameliorate barriers to cochlear implant (CI) access, clinicians must first examine the present demographic composition and spatial distribution of patients completing the candidacy evaluation. This study aims to elucidate potential barriers in hearing healthcare by examining the referral patterns and follow-up attendance of patients at an adult CI clinic in North Carolina to better understand hearing healthcare disparities from a geographic and socioeconomic perspective.

description: The n-type Ge-on-Si epitaxial material platform enables a novel paradigm for plasmonics in the mid-infrared, prompting the future development of lab-on-a-chip and subwavelength vibrational spectroscopic sensors. In order to exploit this material, through proper electrodynamic design, it is mandatory to retrieve the dielectric constants of the thin Ge epilayers with high precision due to the difference from bulk Ge crystals. Here we discuss the procedure we have employed to extract the real and imaginary part of the dielectric constants from normal incidence reflectance measurements, by combining the standard multilayer fitting procedure based on the Drude model with Kramers-Kronig transformations of absolute reflectance data in the zero-transmission range of the thin film.

description: We investigated properties of a singular billiard, that is, a quantum billiard which contains a pointlike (zero-range) perturbation. A singular billiard was simulated experimentally by a rectangular microwave flat resonator coupled to microwave power via wire antennas which act as singular scatterers. The departure from regularity was quantitatively estimated by the short-range plasma model in which the parameter $η$ takes the values $1$ and $2$ for the Poisson and semi-Poisson statistics, respectively. We show that in the regime of semi-Poisson statistics the experimental power spectrum and the second nearest-neighbor spacing distribution $P(2,s)$ are in good agreement with their theoretical predictions. Furthermore, the measurement of the two-port scattering matrix allowed us to evaluate experimentally the enhancement factor $F(γ^{tot})$ in the regime of the semi-Poisson statistics as a function of the total absorption factor $γ^{tot}$. The experimental results were compared with the analytical formula for $F(γ^{tot})$ evaluated in this article. The agreement between the experiment and theory is good.
Feasibility of implementing a group intervention for transdiagnostic repetitive negative thinking in primary care

Publisher: name: No Publisher Supplied

description: Theoretical conceptualizations of psychopathology have shifted from categorical toward dimensional models, prompting a parallel shift toward transdiagnostic approaches to treatment. Repetitive negative thinking (RNT) is a transdiagnostic construct defined as cognitive perseveration on negative themes (e.g., worry and rumination) and has been implicated in the etiology and maintenance of several disorders including depression, generalized anxiety, and social anxiety. Group metacognitive therapy (MCT) has been shown to be effective in treating RNT across diagnoses in specialty mental health settings. Research is limited regarding the implementation of transdiagnostic group treatments in settings outside of specialty mental healthcare settings. The current study sought to explore the feasibility and effectiveness of implementing a group MCT program to address RNT in a primary care setting. Despite active recruitment attempts, the study enrolled only two participants in a family medicine practice with complaints related to RNT. Participants completed six 1.5 hour MCT group sessions and completed outcome measures at pre-treatment, post-treatment, and 4-week follow-up. Primary outcomes were engagement with RNT, anxiety, and depression. Results suggested that group metacognitive therapy delivered in primary care may be effective at decreasing engagement with RNT and improving symptoms of anxiety and depression, as evidenced by the two participants’ improvements on all outcome measures; however, there were significant difficulties with participant recruitment, calling into question the validity of the findings and the feasibility of such a treatment program. Limitations and future directions are discussed, emphasizing specific recommendations for improving recruitment procedures.

description: The thermal instability of accretion disks is widely used to explain the activity of cataclysmic variables, but its development in protoplanetary disks has been studied in less detail. We present a semi-analytical stationary model for calculating the midplane temperature of a gas and dust disk around a young star. The model takes into account gas and dust opacities, as well as the evaporation of dust at temperatures above 1000 K. Using this model, we calculate the midplane temperature distributions of the disk under various assumptions about the source of opacity and the presence of dust. We show that when all considered processes are taken into account, the heat balance equation in the region r<1 au has multiple temperature solutions. Thus, the conditions for thermal instability are met in this region. To illustrate the possible influence of instability on the accretion state in a protoplanetary disk, we consider a viscous disk model with alpha parameterization of turbulent viscosity. We show that in such a model the disk evolution is non-stationary, with alternating phases of accumulation of matter in the inner disk and its rapid accretion onto the star, leading to an episodic accretion pattern. These results indicate that this instability needs to be taken into account in evolutionary models of protoplanetary disks.

description: We formulate and study an integrable model of Nonlinear Schrödinger (NLS)-type through its Lax representation, where one of the Lax operators is quadratic and the other has a rational dependence on the spectral parameter. We discuss the associated spectral problem, the Riemann-Hilbert problem formulation, the conserved quantities, as well as a generalisation for symmetric spaces. In addition we explore the possibilities for modelling with higher order NLS (HNLS) integrable equations and in particular, the relevance of the proposed system.

description: Current vision language pretraining models are dominated by methods using region visual features extracted from object detectors. Given their good performance, the extract-then-process pipeline significantly restricts the inference speed and therefore limits their real-world use cases. However, training vision language models from raw image pixels is difficult, as the raw image pixels give much less prior knowledge than region features. In this paper, we systematically study how to leverage auxiliary visual pretraining tasks to help training end-to-end vision language models. We introduce three types of visual losses that enable much faster convergence and better finetuning accuracy. Compared with region feature models, our end-to-end models could achieve similar or better performance on downstream tasks and run more than 10 times faster during inference. Compared with other end-to-end models, our proposed method could achieve similar or better performance when pretrained for only 10% of the pretraining GPU hours.
