description: We have obtained a deep 8-field XMM-Newton mosaic of M33 covering the galaxy out to the D$_{25}$ isophote and beyond to a limiting 0.2--4.5 keV unabsorbed flux of 5$\times$10$^{-16}$ erg cm$^{-2}$ s$^{-1}$ (L${>}$4$\times$10$^{34}$ erg s$^{-1}$ at the distance of M33). These data allow complete coverage of the galaxy with high sensitivity to soft sources such as diffuse hot gas and supernova remnants. Here we describe the methods we used to identify and characterize 1296 point sources in the 8 fields. We compare our resulting source catalog to the literature, note variable sources, construct hardness ratios, classify soft sources, analyze the source density profile, and measure the X-ray luminosity function. As a result of the large effective area of XMM-Newton below 1 keV, the survey contains many new soft X-ray sources. The radial source density profile and X-ray luminosity function for the sources suggests that only $\sim$15% of the 391 bright sources with L${>}$3.6$\times$10$^{35}$ erg s$^{-1}$ are likely to be associated with M33, and more than a third of these are known supernova remnants. The log(N)--log(S) distribution, when corrected for background contamination, is a relatively flat power-law with a differential index of 1.5, which suggests many of the other M33 sources may be high-mass X-ray binaries. Finally, we note the discovery of an interesting new transient X-ray source, which we are unable to classify.

description: Tunicates populate a great variety of marine underwater substrates worldwide and represent a significant concern in marine shipping and aquaculture. Adhesives are secreted from the anterior papillae of their swimming larvae, which attach and metamorphose into permanently adhering, filter-feeding adults. We recently described the cellular composition of the sensory adhesive organ of the model tunicate Ciona intestinalis in great detail. Notably, the adhesive secretions of collocytes accumulate at the tip of the organ and contain glycoproteins. Here, we further explore the components of adhesive secretions and have screened for additional specificities that may influence adhesion or cohesion of the Ciona glue, including other carbohydrate moieties, catechols and substrate properties. We found a distinct set of sugar residues in the glue recognized by specific lectins with little overlap to other known marine adhesives. Surprisingly, we also detect catechol residues that likely originate from an adjacent cellular reservoir, the test cells. Furthermore, we provide information on substrate preferences where hydrophobicity outperforms charge in the attachment. Finally, we can influence the settlement process by the addition of hydrophilic heparin. The further analysis of tunicate adhesive strategies should provide a valuable knowledge source in designing physiological adhesives or green antifoulants.This article is part of the theme issue ‘Transdisciplinary approaches to the study of adhesion and adhesives in biological systems’.

How Nurses Can Best Support Families of a Child with Autism Spectrum Disorder: A Model Educational Module for BSN Students
Creators: name: Hower, Jennifer

Year: 2021

description: Autism spectrum disorder (ASD) is a developmental condition in around 1.8% of children that results in difficulties with social interaction, speech, and nonverbal communication (CDC, 2020). Diagnosis of ASD is stressful for parents and families, yet a review conducted for this project showed nursing textbooks present a disproportional view of ASD, focusing on severe symptoms and limited information on interventions for family support. This project resulted in a model module to educate BSN students on evidence-based best practices in nursing care with families of children with ASD that use the real experiences of families with ASD to engage students. A focused scoping review of the literature to explore research on families of children with ASD revealed that parents often experience stigma related to the diagnosis, have informational and emotional needs during the initial diagnosis, and benefit from connecting with other parents. Interviews with parents of a child with ASD and a young adult with ASD revealed that families can thrive and successfully support their developing child. The research review, along with reviews of websites for specialty centers for ASD, informational websites on ASD, BSN nursing textbooks, and social media were combined with compelling animated content and the voices of parents to create a model module with educational content, a scavenger hunt of an ASD resource, and reinforcement of concepts through a care plan and a skill exercise. The module was reviewed and critiqued by a BSN educator and will be disseminated in a scholarly publication. Additional resources are provided.

description: We explore ground-state entanglement properties of helium atom confined at the center of an impenetrable spherical cavity of varying radius by using explicitly correlated Hylleraas-type basis set. Results for the dependencies of the von Neumann and linear entanglement entropic measures on the cavity radius are discussed in details. Some highly accurate numerical results for the von Neumann and linear entropy are reported for the first time. It is found that the transition to the strong confinement regime is manifested by the entropies as an appearance of the inflection points on their variations.

Year: 2021

description: Dietary intake throughout the first two years of life is a significant determinant of long-term growth and health. Caregivers are known to shape the diets of young children, though less is known about how caregiver diet influences that of their children in infancy. This study aims to identify and summarize evidence on the associations between caregiver and infant dietary intake and to describe the differences in the associations by type of caregiver. We reviewed the literature for studies that: contained samples of children aged 6-24 months and at least one type of caregiver; assessed intake of foods and food groups excluding breast milk and infant formula; and reported a measure of association between caregiver and child dietary intake. Among the 25 identified studies, three dietary outcomes were evaluated (foods/food groups, dietary patterns, and dietary diversity) for both children and three types of caregivers (mothers, fathers, and grandmothers). Overall, studies found significant positive associations between caregiver and child dietary intake despite the substantial heterogeneity observed, supporting the targeting of caregiver diet in future interventions aimed at influencing child diet. Findings call for additional studies focused on non-maternal caregiver diet and for the standardization of measurement instruments, diet collection methodology, and reporting of results.

description: Zero-Forcing (ZF) has been considered as one of the potential practical precoding and detection method for massive MIMO systems. One of the most important advantages of massive MIMO is the capability of supporting a large number of users in the same time-frequency resource, which requires much larger dimensions of matrix inversion for ZF than conventional multi-user MIMO systems. In this case, Neumann Series (NS) has been considered for the Matrix Inversion Approximation (MIA), because of its suitability for massive MIMO systems and its advantages in hardware implementation. The performance-complexity trade-off and the hardware implementation of NS-based MIA in massive MIMO systems have been discussed. In this paper, we analyze the effects of the ratio of the number of massive MIMO antennas to the number of users on the performance of NS-based MIA. In addition, we derive the approximation error estimation formulas for different practical numbers of terms of NS-based MIA. These results could offer useful guidelines for practical massive MIMO systems.

description: We develop crossing symmetric dispersion relations for describing 2-2 scattering of identical external particles carrying spin. This enables us to import techniques from Geometric Function Theory and study two sided bounds on low energy Wilson coefficients. We consider scattering of photons, gravitons in weakly coupled effective field theories. We provide general expressions for the locality/null constraints. Consideration of the positivity of the absorptive part leads to an interesting connection with the recently conjectured weak low spin dominance. We also construct the crossing symmetric amplitudes and locality constraints for the massive neutral Majorana fermions and parity violating photon and graviton theories. The techniques developed in this paper will be useful for considering numerical S-matrix bootstrap in the future.

The Styles and Distributions of Chunkey Stones in the Eastern Woodlands
Creators: name: Paul, Aidan

Year: 2021

description: Recent studies of the indigenous North American game of chunkey have made it increasingly clear that it played an important role in the political, economic, and religious landscapes of Pre and Post-Colombian Eastern Woodland societies in addition to being a popular recreational activity. However, analysis of chunkey stones themselves, the primary archaeological signature of the game, are limited by an insufficient understanding of genre and style. This study attempts to move towards remedying this issue by conducting a stylistic and distributional analysis on a large sample (n = 266) of discoidals from across the Eastern Woodlands with the goal of systematically separating chunkey stones from other discoidals and identifying styles of chunkey stones and their approximate chronological spans and geographical distributions.

description: A single field inflation based on a supergravity model with a shift symmetry and $U(1)$ extension of the MSSM is analyzed. We show that one of the real components of the two $U(1)$ charged scalar fields plays the role of inflaton {with} an effective scalar potential similar to the "new chaotic inflation" scenario. Both non-anomalous and anomalous (with Fayet-Iliopoulos term) $U(1)$ are studied. We show that the non-anomalous $U(1)$ scenario is consistent with data of the cosmic microwave background and recent astrophysical measurements. A possible kinetic mixing between $U(1)$ {and} $U(1)_{B-L}$ is considered in order to allow for natural decay channels of the inflaton, leading to a reheating epoch. Upper limits on the reheating temperature thus turn out to favour an intermediate ($\sim {\cal O}(10^{13})$ GeV) scale $B-L$ symmetry breaking.

description: Many recent problems in signal processing and machine learning such as compressed sensing, image restoration, matrix/tensor recovery, and non-negative matrix factorization can be cast as constrained optimization. Projected gradient descent is a simple yet efficient method for solving such constrained optimization problems. Local convergence analysis furthers our understanding of its asymptotic behavior near the solution, offering sharper bounds on the convergence rate compared to global convergence analysis. However, local guarantees often appear scattered in problem-specific areas of machine learning and signal processing. This manuscript presents a unified framework for the local convergence analysis of projected gradient descent in the context of constrained least squares. The proposed analysis offers insights into pivotal local convergence properties such as the conditions for linear convergence, the region of convergence, the exact asymptotic rate of convergence, and the bound on the number of iterations needed to reach a certain level of accuracy. To demonstrate the applicability of the proposed approach, we present a recipe for the convergence analysis of projected gradient descent and demonstrate it via a beginning-to-end application of the recipe on four fundamental problems, namely, linear equality-constrained least squares, sparse recovery, least squares with the unit norm constraint, and matrix completion.

Understanding Differences in Prescription Drug Use Between Mexican Americans and Non-Hispanic White Americans: Results from the National Health and Nutrition Examination Survey (NHANES)
Creators: name: Zuckerman, Gabrielle
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021
Subjects: Public health--Research

description: Background: Several studies have found that Mexican Americans are less likely than Non-Hispanic White Americans to use prescription drugs; however, the factors underlying this association remain unclear. We sought to evaluate the factors mediating the association between race/ethnicity and prescription drug use. We also investigated this association among persons with various health conditions to better understand differences in potential for unmet need.

Methods: The exposure of interest was race/ethnicity, comparing Mexican Americans to Non-Hispanic White Americans. The outcome was prescription drug usage within the past 30 days (yes vs no). Several variables were assessed as potential mediators. The percentage mediated and its respective 95% CI was calculated using bootstrapping with 1000 repetitions. Significant mediators were included in a joint difference mediation model that was analyzed using multinomial logistic regression. We also looked at those with diabetes, hypertension, hyperlipidemia, or depression. Logistic regression models were used to calculate odds ratios (unadjusted and fully adjusted) and their 95% CIs for the association between race/ethnicity and use of a prescription drug class corresponding to the condition.

Results: Non-Hispanic whites were more likely to have taken prescription drugs in the past 30 days than Mexican Americans (67.2% vs 37.5%). The joint mediation model mediated 44.3% of the relationship between race/ethnicity and prescription drug use. Among those with diabetes, Mexican Americans were more likely to be treated with an antidiabetic. Among those with hypertension, hyperlipidemia, or depression, Mexican Americans were less likely to be treated than Non-Hispanic whites, with hypertension and depression having statistically significant unadjusted and fully adjusted models.

Conclusions: The association between race/ethnicity and prescription drug use is partially mediated by age, poverty income ratio, and variables reflecting health access. Disparities in prescription drug use persist among those with hypertension and depression. Further investigations should be done to better understand this disparity and the underlying factors contributing to it.

description: We present a Reduced Order Model (ROM) which exploits recent developments in Physics Informed Neural Networks (PINNs) for solving inverse problems for the Navier--Stokes equations (NSE). In the proposed approach, the presence of simulated data for the fluid dynamics fields is assumed. A POD-Galerkin ROM is then constructed by applying POD on the snapshots matrices of the fluid fields and performing a Galerkin projection of the NSE (or the modified equations in case of turbulence modeling) onto the POD reduced basis. A $\textit{POD-Galerkin PINN ROM}$ is then derived by introducing deep neural networks which approximate the reduced outputs with the input being time and/or parameters of the model. The neural networks incorporate the physical equations (the POD-Galerkin reduced equations) into their structure as part of the loss function. Using this approach, the reduced model is able to approximate unknown parameters such as physical constants or the boundary conditions. A demonstration of the applicability of the proposed ROM is illustrated by two cases which are the steady flow around a backward step and the unsteady turbulent flow around a surface mounted cubic obstacle.

description: In cooperatively breeding species, social conflict is typically assumed to underlie destructive behaviours like infanticide. However, an untested alternative hypothesis in birds is that infanticide in the form of egg tossing may simply be a parental response to partial nest predation representing a life-history trade-off. We examined egg tossing behaviour in the colonial and cooperatively breeding grey-capped social weaver (Pseudonigrita arnaudi), a plural breeder in which pairs nest separately, often in the same tree. Using infrared nest cameras, we found that 78% of the tossing events from 2012 to 2017 were committed by parents, suggesting that social conflict is unlikely to be the main reason underlying egg tossing in this species. Instead, reductions in clutch size due to both natural and experimentally simulated predation induced parental egg tossing. Our study suggests that destructive behaviour in cooperatively breeding birds can be shaped by a variety of mechanisms beyond social conflict and that alternative hypotheses must be considered when studying the adaptive significance of infanticide in group-living species.
Regional Geography of Vaccination Uptake and the Impacts of Policy Change in Pennsylvania

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Childhood vaccination in the United States continues to be a pressing issue, as vaccine hesitancy and low levels of vaccine uptake have led to a number of outbreaks. Prior to the 2017 school year, Pennsylvania’s vaccination policy was updated with the intention of reducing the state’s provisional entrance rate and in turn improving vaccination rates among kindergarteners. The new policy reduced the grace period, the timeframe in which provisional entrants must become up-to-date or submit a schedule for becoming up-to-date, from 8 months to 5 days. This project explores the policy’s impact on the global and local clustering of county-level provisional entry rates as well as the relationship between community-level factors and provisional entry rate. Vaccination data for the 2015-16 to 2018-19 school years were obtained from the Pennsylvania Department of Health, and demographic data were gathered from 2014-2018 American Community Survey. Clustering of county-level kindergarten provisional entry rates was not detected prior to the new policy; however, clustering was detected after, suggesting that the policy had a variable impact across counties. Linear regression models indicated that percent White population was consistently a negative predictor of provisional entry rate before and after the policy change. The models also suggested that communities with more adults with less than a high school diploma had a smaller decrease in provisional entry rate. The predictor variables (percent White population, percent adults with less than a high school diploma, and insurance coverage) better captured provisional entry rate following the implementation of the new policy. Pennsylvania’s vaccination policy update resulted in a more predictable distribution of provisional entry rates. Future vaccination campaigns to discourage provisional entrance may focus on regions with more adults without a high school diploma.

description: In 1933-1934 Born and Infeld constructed the first non-linear generalization of Maxwell's electrodynamics that turned out to be a remarkable theory in many respects. In 1935 Heisenberg and Euler computed a complete effective action describing non-linear corrections to Maxwell's theory due to quantum electron-positron one-loop effects. Since then, these and a variety of other models of non-linear electrodynamics proposed in the course of decades have been extensively studied and used in a wide range of areas of theoretical physics including string theory, gravity, cosmology and condensed matter (CMT). In these notes I will overview general properties of non-linear electrodynamics and particular models which are distinguished by their symmetries and physical properties, such as a recently discovered unique non-linear modification of Maxwell's electrodynamics which is conformal and duality invariant. I will also sketch how non-linear electromagnetic effects may manifest themselves in physical phenomena (such as vacuum birefringence), in properties of gravitational objects (e.g. charged black holes) and in the evolution of the universe, and can be used, via gravity/CMT holography, for the description of properties of certain conducting and insulating materials.

0295 Notes on the Early Provenance of Paolo Veronese’s Saint Catherine of Alexandria in Prison
Creators: name: Bubryák, Orsolya
Publisher: name: RIHA Journal
Year: 2023

description: This article provides information about the early provenance of the Paolo Veronese painting entitled Saint Catherine of Alexandria in Prison in The Metropolitan Museum of Art in New York. The painting can most likely be traced back to sixteenth- and seventeenth-century Augsburg. Descriptions that match the Veronese painting are found in the inventories of two very wealthy Augsburg merchants: one is in the post mortem inventory of Octavian Secundus Fugger (ca. 1600/1601), the other in a list of works of art from the collection of Hans Steininger (ca. 1641/42). Octavian Secundus Fugger only occasionally bought paintings from Venice, never seeking to amass a systematic collection of art. The deeply religious Catholic merchant, who was a strong supporter of the Jesuits, hung his picture of Saint Catherine, along with other religious paintings, in the antechapel of his house, and it remained at this location until the early 17th century. The painting’s later owner, however, the Lutheran textile merchant Hans Steininger, was a highly educated art collector who created one of the most illustrious collections in Augsburg. In his Kunstkammer, Veronese’s painting was displayed in the company of mythological female figures, nymphs, and Venus, accompanied by a whole series of paintings by renowned artists such as Hans von Aachen, Christoph Amberger, Paris Bordone, Hans Burgkmair, Joseph Heintz and Titian. Steininger’s collection was dispersed after his death, but many of the paintings he owned can still be identified. Veronese’s Saint Catherine of Alexandria may be one of them.

description: For any positive integers $a$ and $b$, we enumerate all colored partitions made by noncrossing diagonals of a convex polygon into polygons whose number of sides is congruent to $b$ modulo $a$. For the number of such partitions made by a fixed number of diagonals, we give both a recurrence relation and an explicit representation in terms of partial Bell polynomials. We use basic properties of these polynomials to efficiently incorporate restrictions on the type of polygons allowed in the partitions.

description: We establish new interaction estimates for a system introduced by Baiti and Jenssen. These estimates are pivotal to the analysis of the wave front-tracking approximation. In a companion paper we use them to construct a counter-example which shows that Schaeffer's Regularity Theorem for scalar conservation laws does not extend to systems. The counter-example we construct shows, furthermore, that a wave-pattern containing infinitely many shocks can be robust with respect to perturbations of the initial data. The proof of the interaction estimates is based on the explicit computation of the wave fan curves and on a perturbation argument.

The Effect of Lifetime Stress on Accelerated Epigenetic Aging

description: Allostatic load, a measure of the biological aging process, describes the cumulative effect of chronic exposure to stress. The cumulative burden presented by repeated adaptation to stressful events in one’s environment can alter and more importantly, exacerbate the ongoing progression of biological aging and increase susceptibility to aging-related disease onset. Epigenetic biomarkers, such as DNA methylation (DNAm), characteristically accumulate over time to represent biological progression. Current evidence from the literature reports that lifetime PTSD severity and childhood maltreatment are associated with accelerated DNAm age. Despite the robust evidence linking accelerated DNAm aging to these different types of stressors, much remains unknown about the cumulative effect of stress on biological aging throughout one’s lifetime. In the Detroit Neighborhood Health Study (DNHS), we evaluated the effect of a series of life stressors suspected to negatively impact health on accelerated DNAm aging using Horvath and Hannum epigenetic clocks. Cumulative stress was measured and validated using the Holmes-Rahe Stress Scale (full and reduced versions); multiple linear regression models were stratified by gender and social support and adjusted for smoking status, education level, race, and immune cell proportion estimates. We found no evidence of an association between Holmes-Rahe lifetime stress and accelerated DNAm aging (total sample: β= -0.09, 95% CI: -0.94, 0.76); women: β= -0.76, 95% CI: -1.86, 0.33; and men: β= 0.77. 95% CI: -0.68, 2.21). Findings were consistent using the reduced version of the lifetime stress score and among secondary analyses that assessed the association between the count of Holmes-Rahe stressful life events and presence of survivorship bias. It is unclear whether these results between lifetime stress and accelerated DNAm aging are unique to participants in DNHS. Future studies should examine other measures of cumulative life stress in DNHS or other similar neighborhood studies to determine the validity of these observed associations.

description: Discoveries of rotating radio transients and fast radio bursts (FRBs) in pulsar surveys suggest that more of such transient sources await discovery in archival data sets. Here we report on a single-pulse search for dispersed radio bursts over a wide range of Galactic latitudes (|b| < $60^{\circ}$) in data previously searched for periodic sources by Burgay et al. We re-detected 20 of the 42 pulsars reported by Burgay et al. and one rotating radio transient reported by Burke-Spolaor. No FRBs were discovered in this survey. Taking into account this result, and other recent surveys at Parkes, we corrected for detection sensitivities based on the search software used in the analyses and the different backends used in these surveys and find that the all-sky FRB event rate for sources with a fluence above 4.0 Jy ms at 1.4 GHz to be ${\cal R} = 4.4^{+5.2}_{-3.1} \times 10^3$ FRBs day$^{-1}$ sky$^{-1}$, where the uncertainties represent a $99\%$ confidence interval. While this rate is lower than inferred from previous studies, as we demonstrate, this combined event rate is consistent with the results of all systematic FRB searches at Parkes to date and does not require the need to postulate a dearth of FRBs at intermediate latitudes.

description: We consider the phenomenological signatures of Simplified Models of Flavourful Leptoquarks, whose Beyond-the-Standard Model (SM) couplings to fermion generations occur via textures that are well motivated from a broad class of ultraviolet flavour models (which we briefly review). We place particular emphasis on the study of the vector leptoquark $Δ_μ$ with assignments $\left({\bf{3}}, {\bf{1}}, 2/3 \right)$ under the SM's gauge symmetry, $SU(3)_C \times SU(2)_L \times U(1)_Y$, which has the tantalising possibility of explaining both $\mathcal{R}_{K^{(\star)}}$ and $\mathcal{R}_{D^{(\star)}}$ anomalies. Upon performing global likelihood scans of the leptoquark's coupling parameter space, focusing in particular on models with tree-level couplings to a single charged lepton species, we then provide confidence intervals and benchmark points preferred by low(er)-energy flavour data. Finally, we use these constraints to further evaluate the (promising) Large Hadron Collider (LHC) detection prospects of pairs of $τ$-flavoured $Δ_μ$, through their distinct (a)symmetric decay channels. Namely, we consider direct third-generation leptoquark and jets plus missing-energy searches at the LHC, which we find to be complementary. Depending on the simplified model under consideration, the direct searches constrain the $Δ_μ$ mass up to 1500-1770 GeV when the branching fraction of $Δ_μ$ is entirely to third-generation quarks (but are significantly reduced with decreased branching ratios to the third generation), whereas the missing-energy searches constrain the mass up to 1150-1700 GeV while being largely insensitive to the third-generation branching fraction.

description: Στη μεταπτυχιακή αυτή εργασία μελετάται το έργο του 7ου αιώνος του Ιωάννου Μόσχου γνωστό ως Λειμωνάριο. Συγκεκριμένα, παρουσιάζονται οι λειτουργικές μαρτυρίες περί Τυπικού, ακολουθιών, περί της διακρίσεως του ιερατικού χαρίσματος και του μοναχισμού, περί των μυστηρίων του Βαπτίσματος και της θείας Ευχαριστίας, περί της εξοδίου ακολουθίας, της μοναχικής κουράς και της πνευματικής αναδοχής, όπως εντοπίζονται μέσα στις ασκητικές διηγήσεις του Λειμωναρίου. Διερευνάται η λειτουργική συνέχεια και ενότητα της καθολικής Εκκλησίας μέσα από τις διηγήσεις εκείνες, όπου εντοπίζεται, είτε «πλούτος» ή και ίχνος μαρτυριών της λειτουργικής ζωής της Εκκλησίας. Επιζητείται όχι μόνο η προβολή των επί μέρους λειτουργικών στοιχείων, αλλά και η εξελικτική σχέση αυτών των στοιχείων έως τής σήμερον εν τόπω και χρόνω ορθοδόξου λειτουργικής.
description: Τhe Master’s thesis is dedicated to John Moschos' s 7th century work well known as Leimonarion. More specifically, liturgical testimonies are presented in Typicon, in services, in discernment between priesthood and monasticism, in Baptism and in the Eucharist, in funeral traditions as well as in monastic devotion and in spiritual provision as they are found in the ascetic tales of Leimonarion. The thesis examines the liturgical continuity and unity of the Orthodox Catholic Church. Narratives are presented, whether plenty or a trace of testimonies of the liturgical act of the Church are found. Not only is the projection of the individual liturgical elements shown, but also the evolution of these elements, up to the present day, of Orthodox liturgics.
