description: The purpose of this article is to provide a follow up to “Libraries on the Frontlines: Neutrality and Social Justice,” which was published in 2017. It addresses institutional responses to protests and uprising in the spring and summer of 2020 after the deaths of Ahmaud Arbery, Breonna Taylor, and George Floyd—all of which occurred in the context of the global COVID-19 pandemic.  The article expands the previous call for libraries to take a stand for Black Lives. We describe the events of 2020 (a global pandemic, multiple murders of unarmed Black people, and the consequent global protests) and responses from within  library and information science, from our perspectives as women of color faculty and library professionals. We comment on how libraries are responding to current events, as well as the possibilities for panethnic solidarity. We also consider specifically how libraries and other institutions are responding to the racial uprisings through statements on social media and call for concrete action to ensure that their organizations and information practices are actively antiracist. In so doing, we update the claims and expand the appeals we made in 2017—that Black Lives Matter and that librarianship must not remain neutral.

description: The Pixelated silicon Drift Detector (PixDD) is a two-dimensional multi-pixel X-ray sensor based on the technology of Silicon Drift Detectors, designed to solve the dead time and pile-up issues of photon-integrating imaging detectors. Read out by a two-dimensional self-triggering Application-Specific Integrated Circuit named RIGEL, to which the sensor is bump-bonded, it operates in the 0:5 — 15 keV energy range and is designed to achieve single-photon sensitivity and good spectroscopic capabilities even at room temperature or with mild cooling (< 150 eV resolution at 6 keV at 0 °C). The paper reports on the design and performance tests of the 128-pixel prototype of the fully integrated system.

How big is too big: a case study using keyword text analysis and unsupervised machine learning to manage large search results

description: Objectives: To employ the use of a data-driven technique to refine a complicated search strategy by analyzing contributions of individual keywords. To prioritize results from a comprehensive, complex search on a broad topic using machine learning.

Methods: We developed a comprehensive search strategy on a diffuse public health subject that resulted in more than 50,000 results from PubMed. To refine the search strategy, we conducted keyword analysis that indicated the relative contribution by individual keywords and informed our decision-making around terms to exclude from the final search strategy. Using this method we revised the search strategy by eliminating several keywords. After executing the final search, we used unsupervised machine learning or clustering to prioritize a subset of studies for manual review. Specifically, we used a clustering algorithm that groups like references based on text similarities in titles and abstracts. For each cluster, the software produces a set of keywords or a topic “signature”. We used these topic signatures to select clusters to prioritize for manual review.

Results: Our initial search in PubMed yielded approximately 50,000 results. Keyword analysis informed our decisions to eliminate several terms that were causing excessive “noise”. The revised search was reduced to approximately 15,000 records. These records were clustered using unsupervised machine learning and we prioritized approximately 1,400 studies for manual review.

Conclusions: Keyword analysis informs searchers of potentially irrelevant terminology in their search strategies and is useful in shining a light on a set of results at any stage of developing a search strategy. Unsupervised machine learning or clustering assists research groups in prioritizing a subset of literature from a large set of results and is particularly useful for broad, comprehensive literature reviews. Our initial results from manual screening indicate a higher degree of precision than would be typically expected from such a large set of search results.

description: In many developing countries intellectual property infringement and the commerce of pirate goods is an entrepreneurial activity. Digital piracy is very often the only media for having access to music, cinema, books and software. At the same time, bio-prospecting and infringement of indigenous knowledge rights by international consortiums is usual in places with high biodiversity. In these arenas transnational actors interact with local communities. Accusations of piracy often go both ways. This article analyzes the case of southeast Mexico. Using a war of attrition game theory model it explains different situations of intellectual property rights piracy and protection. It analyzes different levels of interaction and institutional settings from the global to the very local. The article proposes free IP zones as a solution of IP disputes. The formation of technological local clusters through Free Intellectual Property Zones (FIPZ) would allow firms to copy and share de facto public domain content for developing new products inside the FIPZ. Enforcement of intellectual property could be pursuit outside of the FIPZ. FIPZ are envisioned as a new type of a sui generis intellectual property regime.

description: Reference or citation managers aid in capturing and managing citations and associated full text, tracking references and citing them properly in manuscripts, and creating bibliographies. With more features than ever, selecting the most appropriate reference manager can be overwhelming for users and librarians. One common situation in which librarians are asked for advice involves building shared libraries of references to support collaborative group work. This project developed a structured evaluation for comparison of several common citation managers and prototypical use cases to help match features with user needs, preferences, and workflows. As products evolve and needs change, is there a “perfect fit”?
Undergraduate Career Choice in Governmental Public Health

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: The governmental public health workforce faces many challenges, including recruitment and retention issues, a lack of diversity, and few professionals with an academic background in public health. Encouraging undergraduates and recent graduates to pursue a career in governmental public health has been identified as a strategy to strengthen this workforce. This study explored the barriers and facilitators to pursuing a job in a federal, state, or local governmental public health agency for public health graduates. The researcher conducted interviews with 10 individuals who graduated between December 2012 and August 2017 with a Bachelor of Science in Public Health degree in Health Policy and Management from the UNC Gillings School of Global Public Health. The most common barriers to entering governmental public health were a “tedious and difficult hiring process,” “difficulty obtaining a government job with only an undergraduate degree,” and a “lack of knowledge about governmental public health roles.” The most common facilitators were “government jobs were closely aligned with interests,” “internship/capstone/work project related to government,” and a “positive family/personal financial situation.” If the government wants highly qualified students to make a career choice in governmental public health, then they must make the hiring process less time-consuming, hidden, and slow. If UNC Gillings hopes to contribute to the governmental public health workforce, they should provide more support for individuals wishing to go into governmental public health.

Luttinger surface dominance and Fermi liquid behaviour of topological Kondo insulators SmB$_6$ and YbB$_{12}$

description: Defying the traditional classification into metals and insulators, several materials simultaneously display metallic thermal properties and insulating electric behaviour, as if they hosted quasiparticles carrying entropy but not charge. Among them, some materials also possess quantum oscillations in magnetic fields as if they had well-defined Fermi surfaces despite the insulating gap. This remarkable dichotomy has been observed in the topological Kondo insulators SmB$_6$ and YbB$_{12}$. Prompted by the peculiar mixed-valence nature of these compounds, involving $f$ and $d$ electrons of the lanthanide, we propose an explanation of their intriguing properties drawing inspiration from the physics of the pseudogap phase in underdoped cuprates. We argue that the $f$ and $d$ subsystems, when considered separately, act, respectively, as electron- and hole-doped Mott insulators, featuring Fermi pockets coexisting with Luttinger surfaces responsible for the pseudogap. When the two are coupled to each other a hybridisation gap opens up, and the whole turns into a topological insulator endowed with genuine chiral edge states. However, the Luttinger surfaces persist and support neutral quasiparticles. This scenario, supported by numerical simulations within the dynamical cluster approximation, effectively resolves the paradoxical phenomenology of SmB$_6$ and YbB$_{12}$.

description: We show that higher form fields, specifically 2- and 3-forms in four spacetime dimensions, suffer from loss of hyperbolicity when they have self interaction. The equations of motion lose their wave-like characteristic in certain parts of the configuration space, and such problematic regions can also be reached dynamically from healthy initial data. These findings are analogous to recent results for vector fields, which are equivalently 1-forms, however, the details of the pathology can be different for higher forms. We also show that the possibility of more than one self interaction term in higher forms also leads to the amelioration of hyperbolicity problems.

We characterize its spectral problem using the modified algebraic Bethe anstaz and study the scalar product between the Bethe vector and its dual. We obtain modified Slavnov and Gaudin-Korepin formulas for the model. Thus we provide a first example of such formulas for quantum integrable models without ${\rm U}(1)$ symmetry characterized by an inhomogenous Baxter T-Q equation.

description: We present the derivation of the NNLO two-parton final state contributions to top pair production in the quark-antiquark channel proportionnal to the leading colour factor $N_c^2$. Together with the three and four-parton NNLO contributions presented in a previous publication, this enables us to complete the phenomenologically most important NNLO corrections to top pair hadro-production in this channel. We derive this two-parton contribution using the massive extension of the NNLO antenna subtraction formalism and implement those corrections in a parton-level event generator providing full kinematical information on all final state particles. In addition, we also derive the heavy quark contributions proportional to $N_h$. Combining the new leading-colour and heavy quark contributions together with the light quark contributions derived previously, we present NNLO differential distributions for LHC and Tevatron. We also compute the differential top quark forward-backward asymmetry at Tevatron and find that our results are in good agreement with the measurements by the D0 collaboration.

description: This paper describes the “DisasterMM: Multimedia Analysis of Disaster-Related Social Media Data” Task at MediaEval 2022. Social media data have been widely used in disaster management and have been proven valuable to all phases of a disaster: from early warning to nowcasting and from response to recovery. Nevertheless, the large streams of user-generated content can be very noisy and usually lack geoinformation, which is an essential attribute. The goal of DisasterMM is to tackle these challenges with two subtasks: RCTP (Relevance Classification of Twitter Posts), which asks participants to build a classifier that will predict whether a tweet is relevant or not to a disaster, in particular floods, and LETT (Location Extraction from Twitter Texts), which calls for a text analysis technique that detects which words inside a Twitter message refer to a location.

Social Media Marketing and the Performing Arts Industry: The Effect of Twitter on Broadway Ticket Sales
Creators: name: Lang, Elizabeth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: The integration of social media marketing into the Theatre District has shifted Broadway from a passive experience to a multi-dimensional dialogue. A Broadway show’s cast and creative team now have the opportunity to connect with fans directly as well as to release social media content to the public for further show enjoyment. What research has yet to address, however, is the extent to which an effective social media presence directly translates into increased ticket sales. My research explores this question by analyzing the effect an active Twitter presence has on weekly ticket grosses for six long running Broadway shows. To examine this relationship, I first performed a series of difference-in-difference estimations to determine if simply creating a Twitter account impacted weekly ticket grosses. I then went into greater depth and ran a multiple regression analysis to determine the extent to which volume of show-related tweets impacted weekly ticket grosses. The results indicate that Twitter and volume of tweets likely do not have a significant impact on ticket sales.

description: Old or waste textiles are a modern phenomenon and a problem of highly industrialised societies. The linear economic model of the textile industry and our appetite for fast fashion has serious impacts on the environment, characterised by short use phases, low reuse and reparability, and low rates of fibre-to-fibre recycling. The European ecodesign requirements regulation establishes a framework for improving the environmental sustainability of products by 2026.1 
This paper focuses on the spinning process using recycled fibres as a sub-sector of the circular economy and the specific hurdles arising from the ecodesign requirements for the design process. 
With concrete, marketable prototypes, the complex challenges relating to the spinning sector are addressed using examples. The development of a prototypical poly-cotton recycled ring yarn from pre-consumer baker uniforms is shown: from materials sourcing to production and product application. This research project combines empirical, experimental approaches in cooperation with textile producers, including research on the framework conditions, regulations and standards which pose real challenges for spinning mills and designers when dealing with mechanically recycled fibres.

description: Very recently, the Belle and BESIII experiments observed a new charmonium-like state $X(3823)$, which is a good candidate for the $D$-wave charmonium $ψ(1^3D_2)$. Because the $X(3823)$ is just near the $D\bar{D}^*$ threshold, the decay $X(3823)\to J/ψπ^+π^-$ can be a golden channel to test the significance of coupled-channel effects. In this work, this decay is considered including both the hidden-charm dipion and the usual quantum chromodynamics multipole expansion (QCDME) contributions. The partial decay width, the dipion invariant mass spectrum distribution $\mathrm{d}Γ[X(3823)\to J/ψπ^+π^-]/\mathrm{d}m_{π^+π^-}$, and the corresponding $\mathrm{d}Γ[X(3823)\to J/ψπ^+π^-]/\mathrm{d}\cosθ$ distribution are computed. Many parameters are determined from existing experimental data, so the results depend mainly only on one unknown phase between the QCDME and hidden-charm dipion amplitudes.

description: In this paper, we investigate the qualitative behavior of an evolutionary problem consisting of a hyperbolic dissipative equation whose trajectories undergo instantaneous impulsive discontinuities at the moments when the energy functional reaches a certain threshold value. The novelty of the current study is that we consider the case in which the entire infinite-dimensional phase vector undergoes an impulsive disturbance. This substantially broadens the existing results, which admit discontinuities for only a finite subset of phase coordinates. Under fairly general conditions on the system parameters, we prove that such a problem generates an impulsive dynamical system in the natural phase space, and its trajectories have nonempty compact ω-limit sets.
Executing Nurse-Driven Protocols to Facilitate Early Extubation after Cardiac Surgery: A Qualitative Descriptive Study
Creators: name: Jones, Chrisha
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Early extubation has become a mainstay method used to streamline recovery for adult post-cardiac surgical patients in the intensive care unit. Given the progressive nature of health care, hospitals and health systems are utilizing nurses at the bedside to wean patients from mechanical ventilatory support. While there is literature that examines the risks and benefits of implementing nurse-driven early extubation protocols to fast track the extubation process, there is a gap in literature regarding nurses’ perceptions and knowledge of the practice. The purpose of this qualitative descriptive, pilot study was to systematically investigate empirical evidence that supports the use of nurse-driven protocols to facilitate early extubation from mechanical ventilation in adult post-cardiac surgical patients. Two registered nurses from a single cardiothoracic intensive care unit (CVICU) in a southeast teaching hospital participated in structured interviews to yield accounts of their experiences and perceptions. The interviews were conducted to identify the two nurses' knowledge, attitude, comfort level, and perception of nurse-driven early extubation protocols. The interviews were transcribed verbatim and identifiable themes were extracted. As a result, the following themes emerged: Education, Resources, Independence, and Positive Patient Outcomes. This study will serve as a pilot for future research needed to identify nurses’ knowledge and perception of executing nurse-driven extubation protocols. This may support the extension of nurse-driven early extubation protocols across more intensive care units and allow nurses working at the bedside to practice to the full extent of their education and training.

description: The exponential growth of data generated by sequencing, imaging, and electronic medical records highlights the need for tools to exploit multimodal biomedical data. The objective of my thesis is to develop methods based on artificial intelligence to explore data from patients with congenital myopathies, a family of rare genetic diseases difficult to diagnose. First, I developed IMPatienT (Integrated digital Multimodal PATIENt daTa), a database for annotating and exploring patient reports and histological images. Then I developed NLMyo (Natural Language Myopathies), a tool based on large language models such as GPT-3.5 and LLaMA. NLMyo allows to anonymize and extract information from medical reports, to do diagnostic assistance and to create a patient search engine. Finally, I developed MyoQuant a tool using AI models to automatically quantify pathological markers in muscle fiber biopsies. IMPatient, NLMyo and MyoQuant are available as open-source and online demo versions.

description: Significant advances in coherence have made superconducting quantum circuits a viable platform for fault-tolerant quantum computing. To further extend capabilities, highly coherent quantum systems could act as quantum memories for these circuits. A useful quantum memory must be rapidly addressable by qubits, while maintaining superior coherence. We demonstrate a novel superconducting microwave cavity architecture that is highly robust against major sources of loss that are encountered in the engineering of circuit QED systems. The architecture allows for near-millisecond storage of quantum states in a resonator while strong coupling between the resonator and a transmon qubit enables control, encoding, and readout at MHz rates. The observed coherence times constitute an improvement of almost an order of magnitude over those of the best available superconducting qubits. Our design is an ideal platform for studying coherent quantum optics and marks an important step towards hardware-efficient quantum computing with Josephson junction-based quantum circuits.

description: In quantum information processing, two primary research directions have emerged: one based on discrete variables (DV) and the other on the structure of quantum states in a continuous-variable (CV) space. Integrating these two approaches could unlock new potentials, overcoming their respective limitations. Here, we show that such a DV-CV hybrid approach, applied to superconducting Kerr parametric oscillators (KPOs), enables us to entangle a pair of Schrödinger's cat states by two methods. The first involves the entanglement-preserving conversion between Bell states in the Fock-state basis (DV encoding) and those in the cat-state basis (CV encoding). The second method implements a $\sqrt{\textrm{iSWAP}}$ gate between two cat states following the procedure for Fock-state encoding. This simple and fast gate operation completes a universal quantum gate set in a KPO system. Our work offers powerful applications of DV-CV hybridization and marks a first step toward developing a multi-qubit platform based on planar KPO systems.
MEDICAID WORK REQUIREMENTS: THE IMPACT ON PAYER MIX, OPERATING MARGINS, AND UNCOMPENSATED CARE COSTS AT DISPROPORTIONATE-SHARE HOSPITALS IN NORTH CAROLINA
Creators: name: Noble, John

description: Medicaid work requirements are a relatively new policy, coming into effect January 2018. While the current literature focuses on coverage loss for Medicaid recipients, this honor thesis examines the impacts of implementing Medicaid work requirements in North Carolina. I examine the effects of Medicaid work requirements on payer mix, operating margins, and uncompensated care costs of Disproportionate-Share Hospitals in North Carolina. Using a quantitative approach with hospital data from the Centers for Medicare and Medicaid Services, this study concludes that work requirements significantly impacts payer mix, operating margins, and uncompensated care costs. The results indicate that work requirements could decrease the Medicaid payer mix by 2% at hospitals. Additionally, my research suggests that operating margins improve between 1.8% and 2.0% while uncompensated care costs increase between 3.3% and 3.4%. The results indicate that while hospital margins could improve with work requirements, the increases would be outweighed by the increases in uncompensated care costs.

Improved determination of sterile neutrino dark matter spectrum

description: The putative recent indication of an unidentified 3.55 keV X-ray line in certain astrophysical sources is taken as a motivation for an improved theoretical computation of the cosmological abundance of 7.1 keV sterile neutrinos. If the line is interpreted as resulting from the decay of Warm Dark Matter, the mass and mixing angle of the sterile neutrino are known. Our computation then permits for a determination of the lepton asymmetry that is needed for producing the correct abundance via the Shi-Fuller mechanism, as well as for an estimate of the non-equilibrium spectrum of the sterile neutrinos. The latter plays a role in structure formation simulations. Results are presented for different flavour structures of the neutrino Yukawa couplings and for different types of pre-existing lepton asymmetries, accounting properly for the charge neutrality of the plasma and incorporating approximately hadronic contributions.

How Does Location of Donor and Recipient Impact the Diversity of Surplus Food Redistributed in New York City?
Creators: name: Omens, Allie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: This thesis explores the implementation of donateNYC food portal for redistributing surplus food in the New York City area. This thesis serves as a preliminary program analysis for the portal and seeks to answer if the location of donateNYC donor and recipient impacts what food is being donated on the platform. Through this thesis, a Donation Network tool is developed to visualize donateNYC transactions. 

This thesis recommends that focus should be placed on targeting donateNYC food portal to the five boroughs (Manhattan, Brooklyn, Queens, The Bronx, and Staten Island) with care for catering to each neighborhood’s demographics. Each borough in New York City has potential for taking up the program, and this thesis asserts that neighborhoods in Southeastern Brooklyn could greatly benefit from additional donateNYC food portal activity and the Queens borough represents a large area of untapped potential in both potential donors. This thesis lends insights for food rescue in other major cities across the United States under the assumption of food portals being adopted to support preexisting food rescue. The Donation Network tool should continue to be updated and expanded to continue to understand how this portal is being used throughout the city.

description: We present a proof of concept design for a structured square cloak enclosing a void in an elastic lattice, subjected to flexural vibrations. In addition to the theoretical design, we fabricate and experimentally test an elastic invisibility cloak for flexural waves in a mechanical lattice. Further verification and modelling is performed numerically through finite element simulations. The primary advantage of our square lattice cloak, over other designs, is the straightforward implementation and the ease of construction. The elastic lattice cloak shows an impressive efficiency within the predicted frequency range of 100-250Hz.

description: We investigate even-even two-proton borromean systems at prominent intermediate heavy waiting points for the rapid proton capture process. The most likely single-particle levels are used to calculate three-body energy and structure as a function of proton-core resonance energy. We establish a linear dependence between two- and three-body energies with the same slope, but the absolute value slightly dependent on partial wave structure. Using these relations we predict low-lying excited states in the isotones following the critical waiting points. The capture rate for producing a borromean bound state is described both based on a full three-body calculation and on a very simple analytic rate expression for temperatures about $1-5$~GK. This rate is valid for both direct and sequential capture paths, and it only depends on the three-body resonance energy. As a result the relevant path of the radiative capture reactions can be determined. We present numerical results for $E1$ and $E2$ photon emission, and discuss occurrence preferences in general as well as relative sizes of these most likely processes. Finally, we present narrow estimated intervals for the proton capture rates relevant for the critical waiting points.
