Wiggle Instability of Galactic Spiral Shocks: Effects of Magnetic Fields

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: It has been suggested that the wiggle instability (WI) of spiral shocks in a galactic disk is responsible for the formation of gaseous feathers observed in grand-design spiral galaxies. We perform both a linear stability analysis and numerical simulations to investigate the effect of magnetic fields on the WI. The disk is assumed to be infinitesimally-thin, isothermal, and non-self-gravitating. We control the strengths of magnetic fields and spiral-arm forcing using the dimensionless parameters $β$ and $\mathcal{F}$, respectively. By solving the perturbation equations as a boundary-eigenvalue problem, we obtain dispersion relations of the WI for various values of $β=1-\infty$ and $\mathcal{F}=5\%$ and $10\%$. We find that the WI arising from the accumulation of potential vorticity at disturbed shocks is suppressed, albeit not completely, by magnetic fields. The stabilizing effect of magnetic fields is not from the perturbed fields but from the unperturbed fields that reduce the density compression factor in the background shocks. When $\mathcal{F}=5\%$ and $β\lesssim 10$ or $\mathcal{F}=10\%$ and $β\sim5-10$, the most unstable mode has a wavelength of $\sim0.1-0.2$ times the arm-to-arm separation, which appears consistent with a mean spacing of observed feathers.

description: Photodeposition is a specific method for depositing metallic co-catalysts onto photocatalysts and was applied for immobilizing platinum nanoparticles onto cellulose, a photocatalytically inactive biopolymer. The obtained Pt@cellulose catalysts show narrow and well-dispersed nanoparticles with average sizes between 2 and 5 nm, whereby loading, size and distribution depend on the preparation conditions. The catalysts were investigated for the hydrogenation of para-nitrophenol via transfer hydrogenation using sodium borohydride as the hydrogen source, and the reaction rate constant was determined using the pseudo-first-order reaction rate law. The Pt@cellulose catalysts are catalytically active with rate constant values k from 0.09 × 10−3 to 0.43 × 10−3 min−1, which were higher than the rate constant of a commercial Pt@Al2O3 catalyst (k = 0.09 × 10−3 min−1). Additionally, the Pt@cellulose catalyst can be used for electrochemical hydrogenation of para-nitrophenol where the hydrogen is electrocatalytically formed. The electrochemical hydrogenation is faster compared to the transfer hydrogenation (k = 0.11 min−1).

description: Introduction: With the increasing severity of the opioid epidemic in America, there has been an increase in publications addressing this urgent issue.  However, no systematic analysis has been performed to identify who the main researchers are, where these studies are the published, and what topics are they publishing on. Objectives: This study conducted a bibliometric analysis on opioid-related research publications produced at the University of North Carolina-Chapel Hill (UNC-CH).Methods: Bibliometric methods were used to reveal the research productivity within opioid research at UNC-CH.  Organizational and country collaboration networks were generated to show the collaborated working with UNC-CH researchers.  The topic analysis illustrated the range in topics over the past 20 years.Results: The results demonstrate that there has been a shift in topics over the past 20 years as well as the increase in collaboration with other academic research institutions.
A Critical Discourse Analysis of the Historical Development of the Library Bill of Rights

Year: 2019

description: This study describes a critical discourse analysis of the officially adopted versions of the American Library Association’s Library Bill of Rights (LBR). This analysis was performed to examine how –if at all– the LBR has materially changed since its initial version, and what this might say about the document itself, and its relationship to librarianship.  The five official versions of the LBR from 1939-2019 were analyzed using Stuart Hall’s models of encoding/decoding and hegemony. The language of iteration was examined individually as well as relative to previous and subsequent versions of the document. A taxonomy was then developed. The data and their analysis suggest the LBR is the discursive practice through which hegemonic consent is created and rearticulated.

description: The tonal noise generated at the tip is a major contribution to the aerodynamic noise generated by three-dimensional airfoils. One way to reduce this noise is the use of end plates, which was investigated in the present study for three different circular end plate geometries applied to a cambered NACA 4412 airfoil with aspect ratio 2 and forced boundary layer transition. Microphone array measurements were performed in a small aeroacoustic wind tunnel for chord based Reynolds numbers between 75,000 and 200,000 and geometric angles of attack between 0° and 20°. The acoustic far-field noise spectra obtained for the baseline configuration show a broadband hump centered at a chord based Strouhal number of 13 that is associated with the noise generation at the tip and scales with the third power of the flow velocity. The application of end plates reduces this peak and is most effective for end plates which bound the flow on the suction side of the airfoil. Hot-wire measurements taken for one configuration show that the end plates diffuse the turbulence intensity in the relevant frequency range and reduce the fluid transfer along the pressure gradient at the tip. The suction side end plate additionally prevents the interaction of turbulent structures with the trailing edge and is therefore more effective in reducing noise. Surface flow visualizations for this configuration reveal a separation line extending along the full span up to the tip while the surface flow of the baseline and pressure configuration is strongly affected by the flow swept around the tip. Therefore, the placement of the end plate on the suction side is more effective in reducing tip noise.
Framework for Version Control & Dependency Link of Components & Products in a Software Product Line

description: Software product line deals with the assembly of products from existing core assets commonly known as components and continuous growth in the core assets as we proceed with production. This idea has emerged as vital in terms of software development from component-based architecture. Since in software product line one has to deal with number of products and components simultaneous therefore there is a need to develop a strategy, which will help to store components and products information in such a way that they can be traced easily for further development. This storage strategy should reflect a relationship between products and components so that product history with reference to components can be traced and vise versa. In this paper we have presented a tree structure based storage strategy for components and products in software product line. This strategy will enable us to store the vital information about components and products with a relationship of their composition and utilization. We implemented this concept and simulated the software product line environment.
Availability and Range of Large Print Books for Children and Teens in North Carolina Public Libraries

description: Several studies have shown that large swaths of our younger patrons suffer from vision issues, and especially undiagnosed vision issues.  Additionally, research has shown that large print books can help children with vision issues, like low vision and dyslexia.  This study examined the catalogs of five of the best funded public libraries in North Carolina, searching for books labeled both as large print and for children and teens.   The available items meeting this criteria did not meet the collection development policies set out by the libraries.  Of the five total libraries surveyed, there were only 52 books that appeared when searching for large print and children or teens.  Furthermore, adults make up 55-80% of the readership for YA books.  For these reasons, large print versions of children and teen books should be collected.

description: Stable ultrashort light pulses and frequency combs generated by mode-locked lasers have many important applications including high-resolution spectroscopy, fast chemical detection and identification, studies of ultrafast processes, and laser metrology. While compact mode-locked lasers emitting in the visible and near infrared range have revolutionized photonic technologies, the systems operating in the mid-infrared range where most gases have their strong absorption lines, are bulky and expensive and rely on nonlinear frequency down-conversion. Quantum cascade lasers are the most powerful and versatile compact light sources in the mid-infrared range, yet achieving their mode locked operation remains a challenge despite dedicated effort. Here we report the first demonstration of active mode locking of an external-cavity quantum cascade laser. The laser operates in the mode-locked regime at room temperature and over the full dynamic range of injection currents of a standard commercial laser chip.

description: Usage statistics have consistently been an integral part of collection development for libraries and archives, as they allow the staff to understand what kinds and types ofmaterials their patrons want. As more of these institutions turn to digitization to make their materials accessible, usage statistics become more important as digital materials canbe costly. In this exploratory paper, I tracked the usage of recently digitized materials from the North Carolina Collection at Wilson Library that were uploaded to both the Internet Archive and the HathiTrust. As the study lasted for two months and one month,respectively, I can draw no strong conclusions from the data, but rather a baseline for further studies for this collection.
title: I, Daniel
title: An Illegitimate Reading of Jacques Derrida's "Envois"
titleType: Subtitle
Creators: name: Stewart, Jeremy
Publisher: name: Lancaster University
Year: 2023

description: Much creative-critical writing is characterized by a desire to find space within academia for otherwise marginalized experiences. This is often a case of drawing on personal, emotional, or spiritual registers typically excluded from academic writing, and thus rendered illegitimate. This thesis is a case in point, as it draws, inter alia, on my dreams, my Christian faith, my middle name, and, indeed that I was born, as they say, outside of wedlock – illegitimate, if you will, outside the law. My primary text is Jacques Derrida’s “Envois,” the opening section of his book The Post Card: From Socrates to Freud and Beyond (University of Chicago Press, 1987). It has often been read in purely philosophical terms but Derrida, alluding to Freud’s talk of “theoretical fiction,” describes it as a “project for a ‘fiction.’” “Envois” is, then, a text that could itself be said to be a work of creative-critical writing – not least because of its very personal character. “Envois” takes the form of hundreds of postcards to an unnamed lover. Central to my exploration is a figure called ‘Daniel.’ In some respects, he is myself, since my middle name is Daniel, and in some respects, he is Daniel Agacinski, Derrida’s unrecognized son. This Daniel was born in 1984 to Sylviane Agacinski, the woman who is believed to be the unnamed lover addressed throughout “Envois.” As Derrida’s biographer, Benoit Peeters, writes, “everything suggests that the original version [of “Envois”] was written for Sylviane Agacinski.” One of “Envois’” key conceits is that it is “the preface to a book […] not [yet] written.” Taking, as my cues, fleeting references to the biblical book of Daniel and George Eliot’s novel Daniel Deronda, I proceed as though “Envois” is a preface not so much to an unwritten book but to the text that is the name ‘Daniel.’ My own theoretical fiction, then, is the story of my succumbing to the temptation to see myself mirrored in Daniel Agacinski – a Daniel who, like myself, and indeed my thesis, is what one might call a bastard.

description: Search in an environment with an uncertain distribution of resources involves a trade-off between exploitation of past discoveries and further exploration. This extends to information foraging, where a knowledge-seeker shifts between reading in depth and studying new domains. To study this decision-making process, we examine the reading choices made by one of the most celebrated scientists of the modern era: Charles Darwin. From the full-text of books listed in his chronologically-organized reading journals, we generate topic models to quantify his local (text-to-text) and global (text-to-past) reading decisions using Kullback-Liebler Divergence, a cognitively-validated, information-theoretic measure of relative surprise. Rather than a pattern of surprise-minimization, corresponding to a pure exploitation strategy, Darwin's behavior shifts from early exploitation to later exploration, seeking unusually high levels of cognitive surprise relative to previous eras. These shifts, detected by an unsupervised Bayesian model, correlate with major intellectual epochs of his career as identified both by qualitative scholarship and Darwin's own self-commentary. Our methods allow us to compare his consumption of texts with their publication order. We find Darwin's consumption more exploratory than the culture's production, suggesting that underneath gradual societal changes are the explorations of individual synthesis and discovery. Our quantitative methods advance the study of cognitive search through a framework for testing interactions between individual and collective behavior and between short- and long-term consumption choices. This novel application of topic modeling to characterize individual reading complements widespread studies of collective scientific behavior.

description: This study examined the themes present in Diversity Statements of libraries at schools with an ALA Accredited program in Library and Information Studies. A quantitative and qualitative content analysis method was conducted using a coding scheme found in the literature which coded for themes in university diversity statements. In addition, strong emergent themes specific to Library Diversity Statements were coded for as well. Results indicate that very few libraries have Diversity Statements available online, and of those that do, many are more focused on the Library or the University than they are focused on diversity.

description: We introduce a unitary matrix-product operator (UMPO) based variational method that approximately finds all the eigenstates of fully many-body localized (fMBL) one-dimensional Hamiltonians. The computational cost of the variational optimization scales linearly with system size for a fixed bond dimension of the UMPO ansatz. We demonstrate the usefulness of our approach by considering the Heisenberg chain in a strongly disordered magnetic field for which we compare the approximation to exact diagonalization results.

description: Purpose: Across Australia and New Zealand, speech-language pathologists (SLPs) routinely assess and treat adults with cognitive-communication disorders following traumatic brain injury (TBI). Despite their regular involvement, little is known about how clinicians provide management to this client group, particularly in community-based contexts. Therefore the aim of this study is to explore the clinical practices of SLPs who have experience working in community-based rehabilitation services with adults with cognitive-communication disorders following TBI. Method: A qualitative descriptive study using one-on-one semi-structured interviews was conducted as part of an explanatory sequential mixed-methods design. Fourteen SLPs with experience working with individuals with TBI completed an interview with content analysis used to explore the data. Result: The overarching theme identified was that a “Client-centred and inclusive approach to community-based rehabilitation services” is required. The three subthemes to emerge from the data included the importance of utilising a (1) “flexible service delivery approach”, with (2) “meaningful therapy focus”, and (3) “collaboration” with multidisciplinary team members and significant others when managing this client group. Conclusion: SLPs play a crucial role in client-centred inclusive rehabilitation for community-dwelling adults with cognitive-communication disorders following TBI. The complexity of working with this population requires current and future models of care to incorporate an interdisciplinary approach that is flexible in its delivery and meaningful in focus.

description: This paper examines university students and their knowledge, concerns and actions in regards to privacy of personal data on Facebook.  As Facebook continues to grow, it is important that users are aware of the types of information Facebook is collecting and how users can protect themselves. This paper uses interviews to determine whether or not focus of study and level of education contribute to a Facebook users’ level of knowledge on the data Facebook collects, their privacy concerns and their likelihood to act to protect their personal data. The interviews provided results showing that graduate students studying Information Science are more knowledgeable and act to protect personal information more than undergraduates from various majors. This arises the suggestion that undergraduate studies should require online personal privacy courses.

description: We construct the classical phase space of geometries in the near-horizon region of vacuum extremal black holes as announced in [arXiv:1503.07861]. Motivated by the uniqueness theorems for such solutions and for perturbations around them, we build a family of metrics depending upon a single periodic function defined on the torus spanned by the $U(1)$ isometry directions. We show that this set of metrics is equipped with a consistent symplectic structure and hence defines a phase space. The phase space forms a representation of an infinite dimensional algebra of so-called symplectic symmetries. The symmetry algebra is an extension of the Virasoro algebra whose central extension is the black hole entropy. We motivate the choice of diffeomorphisms leading to the phase space and explicitly derive the symplectic structure, the algebra of symplectic symmetries and the corresponding conserved charges. We also discuss a formulation of these charges with a Liouville type stress-tensor on the torus defined by the $U(1)$ isometries and outline possible future directions.

description: Three-dimension will be a characteristic of future user interfaces, although we are just starting to gain an understanding of how users can navigate and share information within a virtual 3D environment. Three-dimensional graphical user interfaces (3D-GUI) raise many issues of design, metaphor and usability. This research is devoted to designing a 3D-GUI as a front-end tool for a file management system, in this case, for Microsoft Windows\c{opyright} Explorer; as well as evaluating the efficiency of a 3D application. The software design was implemented by extending the Half-Life 3D engine. This extension provides a directory traversal and basic file management functions, like cut, copy, paste, delete, and so on. This paper shows the design and implementation of a real-world application that contains an efficient 3D-GUI.

description: This project-based study implements a high recall and high precision interactive literature retrieval system based on the ReQuery-ReClassify (ReQ-ReC) framework proposed by Wang et al. in 2014. The study summarizes the challenges and difficulties of current methods of literature retrieval and review in achieving high recall in addition to high precision. Following the double-loop mechanism of the ReQ-ReC framework, the project applies the methodology of system design, database design and user interface design to turn the framework into a real-world web application. Heuristic evaluation for the user interface design indicates that the system is user-friendly and can be integrated with literature retrieval systems like PubMed.

description: We study the stochastic homogenization and obtain a random fluctuation theory for semilinear elliptic equations with a rapidly varying random potential. To first order, the effective potential is the average potential and the nonlinearity is not affected by the randomness. We then study the limiting distribution of the properly scaled homogenization error (random fluctuations) in the space of square integrable functions, and prove that the limit is a Gaussian distribution characterized by the homogenized solution, the Green's function of the linearized equation around the homogenized solution, and by the integral of the correlation function of the random potential. These results enlarge the scope of the framework that we have developed for linear equations to the class of semilinear equations.

Year: 2019

description: This paper explores how growth in the field of Chinese Studies has affected subject trends in academic publications, library holdings, and usage of Chinese Studies materials from 1992 to 2017. Using data on academic monographs published from EBSCO’s GOBI (Global Online Bibliographic Information), comparisons were made with subject trends found in the Chinese Studies print collection at the University of North Carolina at Chapel Hill. Contrary to expectation, there was no discernible increase in social science literature relative to other subjects. Meaningful findings included an increased diversity in topics covered and the continuity in traditional areas of strength for Chinese-language resources. This paper also describes the methodology for using library metadata to measure subject trends, and discusses potential explanations for specific findings.

description: Purpose: There is poor reporting of the cost of simulation and greater transparency is needed. The primary study aim was to conduct a financial analysis of the university/training institution costs associated with a 5-day simulation-based learning program for speech–language pathology students. The secondary aim was to consider the economic costs of the model. Method: Costs associated with the delivery of a 5-day simulation-based learning program for speech–language pathology students from six Australian universities were collected regarding: (a) pre-program training, (b) personnel, (c) room hire, (d) equipment, and (e) consumables. Both financial costs and economic costs (Australian dollar, at June 2017) were calculated per university site, and per student. Result: The simulation program was run 21 times involving 176 students. Average total financial cost per program ranged from $4717 to $11 425, with cost variation primarily attributed to local labour costs and various use of in-kind support. Average financial cost per student was $859 (range $683–$1087), however this was almost double ($1461 per student, range $857–$2019) in the economic cost calculation. Personnel was the largest contributing cost component accounting for 76.6% of financial costs. Personnel was also the highest contributing cost in the economic analysis, followed by room hire. Conclusion: This study provides clarity regarding financial and economic costing for a 5-day simulation-based learning program. These data can help universities consider potential up-front financial costs, and well as strategies for financial cost minimisation, when implementing simulation-based learning within the university context.

description: Recent broad-band 34 and 44 GHz radio continuum observations of the Galactic center have revealed 41 massive stars identified with near-IR counterparts, as well as 44 proplyd candidates within 30" of Sgr A*. Radio observations obtained in 2011 and 2014 have been used to derive proper motions of eight young stars near Sgr A*. The accuracy of proper motion estimates based on near-IR observations by Lu et al. and Paumard et al. have been investigated by using their proper motions to predict the 2014 epoch positions of near-IR stars and comparing the predicted positions with those of radio counterparts in the 2014 radio observations. Predicted positions from Lu et al. show an rms scatter of 6 mas relative to the radio positions, while those from Paumard et al. show rms residuals of 20 mas, which is mainly due to uncertainties in the IR-based proper motions. Under the assumption of homogeneous ionized winds, we also determine the mass-loss rates of 11 radio stars, finding rates that are on average $\sim$2 times smaller than those determined from model atmosphere calculations and near-IR data. Clumpiness of ionized winds would reduce the mass loss rate of WR and O stars by additional factors of 3 and 10, respectively. One important implication of this is a reduction in the expected mass accretion rate onto Sgr A* from stellar winds by nearly an order of magnitude to a value of few$\times10^{-7}$ \msol\ yr$^{-1}$. Finally, we present the positions of 318 compact 34.5 GHz radio sources within 30\arcs\ of Sgr A*. At least 45 of these have stellar counterparts in the near-IR $K_s$ (2.18 $μ$m) and $L'$ (3.8$μ$m) bands.

An Analysis of Upwork Profiles: Visualizing Characteristics of Gig Workers using Digital Platform
Creators: name: Bang, Eugene
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: In the transitional period of manual and algorithmic hiring, there has been an explosion of new employment opportunities. As a result of the ubiquity of mobile communication technologies, a gig economy has emerged which champions digital platforms as a solution to meet the burgeoning demand for on-demand workers, frequently called independent contractors or freelancers, by hiring organizations. Visualizations and linear regression are used to study information-rich Upwork profiles to determine variables that could predict how users maneuver in the gig economy. A typology of existing gig workers’ motivations is combined with visualizations to better understand the situation of the typical gig economy worker.

description: Purpose: This study presented an initial step towards developing the evidence base for intergenerational choral singing as a communication-focussed rehabilitative approach for Parkinson’s disease (PD). Method: A theoretical framework was established to conceptualise the rehabilitative effect of intergenerational choral singing on four domains of communication impairments – motor drive, timing mechanism, sensorimotor integration, higher-level cognitive and affective functions – as well as activity/participation, and quality of life. A computer-assisted multidimensional acoustic analysis was developed to objectively assess the targeted domains of communication impairments. Voice Handicap Index and the World Health Organization’s Quality of Life assessment-abbreviated version were used to obtain patient-reported outcomes at the activity/participation and quality of life levels. As a proof of concept, a single subject with PD was recruited to participate in 9 weekly 1-h intergenerational choir rehearsals. The subject was assessed before, 1 week post, and 8 weeks post-choir. Result: Notable trends of improvement were observed in multiple domains of communication impairments at 1 week post-choir. Some improvements were maintained at 8 weeks post-choir. Patient-reported outcomes exhibited limited pre-post changes. Conclusion: This study provided the theoretical groundwork and an empirical measurement tool for future validation of intergenerational choral singing as a novel rehabilitation for PD.

description: Purpose: Improving language and literacy skills in preschoolers can lead to better life outcomes. One way speech-language pathologists (SLPs) can improve these skills in preschoolers is by supporting educators through professional development (PD). However, PD in early childhood education and care (ECEC) settings is a complex intervention. To improve preschoolers' language and literacy skills using PD, SLPs must first work with educators to change or increase educators' language and literacy-promoting behaviours. This paper aimed to describe educator behaviours and preschooler skills following a real-world language and literacy PD intervention facilitated by two community SLPs. Method: Two pragmatic studies were conducted across four ECEC centres: (1) an observation study of 13 educators' self-reported language and literacy promoting behaviours, and (2) a non-randomised controlled trial investigating the language and literacy skills of 82 preschoolers as reported by their educators and parents/carers. Result: After the intervention, educators rated themselves as performing language and literacy-promoting behaviours more frequently. Educators also rated the early reading skills of preschoolers more highly after the PD intervention, but not preschoolers' oral language or early writing skills. Parents/carers did not report any significant improvements in preschoolers' skills. Conclusion: PD as an SLP intervention, whilst promising, showed mixed outcomes. Educator outcomes improved; however, preschooler outcomes were varied.

description: Purpose: There is poor reporting of the cost of simulation and greater transparency is needed. The primary study aim was to conduct a financial analysis of the university/training institution costs associated with a 5-day simulation-based learning program for speech–language pathology students. The secondary aim was to consider the economic costs of the model. Method: Costs associated with the delivery of a 5-day simulation-based learning program for speech–language pathology students from six Australian universities were collected regarding: (a) pre-program training, (b) personnel, (c) room hire, (d) equipment, and (e) consumables. Both financial costs and economic costs (Australian dollar, at June 2017) were calculated per university site, and per student. Result: The simulation program was run 21 times involving 176 students. Average total financial cost per program ranged from $4717 to $11 425, with cost variation primarily attributed to local labour costs and various use of in-kind support. Average financial cost per student was $859 (range $683–$1087), however this was almost double ($1461 per student, range $857–$2019) in the economic cost calculation. Personnel was the largest contributing cost component accounting for 76.6% of financial costs. Personnel was also the highest contributing cost in the economic analysis, followed by room hire. Conclusion: This study provides clarity regarding financial and economic costing for a 5-day simulation-based learning program. These data can help universities consider potential up-front financial costs, and well as strategies for financial cost minimisation, when implementing simulation-based learning within the university context.
