description: Building on our previous cross-correlation analysis (Xia et al. 2011) between the isotropic gamma-ray background (IGRB) and different tracers of the large-scale structure of the universe, we update our results using 60-months of data from the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope. We perform a cross-correlation analysis between the IGRB and objects that may trace the astrophysical sources of the IGRB: SDSS-DR6 QSOs, the SDSS-DR8 Main Galaxy Sample, Luminous Red Galaxies (LRGs) in the SDSS catalog, 2MASS galaxies, and radio NVSS galaxies. The benefit of correlating the Fermi-LAT signal with catalogs of objects at various redshifts is to provide tomographic information on the IGRB which is crucial to separate the various contributions and to clarify its origin. We observe a significant (>3.5 sigma) cross-correlation signal on angular scales smaller than 1 deg in the NVSS, 2MASS and QSO cases and, at lower statistical significance (~3.0 sigma), with SDSS galaxies. These results are robust against the choice of the statistical estimator, estimate of errors, map cleaning procedure and instrumental effects. Finally, we test the hypothesis that the IGRB observed by Fermi-LAT originates from the summed contributions of three types of unresolved extragalactic sources: BL Lacs, FSRQs and Star-Forming Galaxies (SFGs). We find that a model in which the IGRB is mainly produced by SFGs ($72^{+23}_{-37}$% with 2 sigma errors), with BL Lacs and FSRQs giving a minor contribution, provides a good fit to the data. We also consider a possible contribution from Misaligned Active Galactic Nuclei, and we find that, depending on the details of the model and its uncertainty, they can also provide a substantial contribution, partly degenerate with the SFG one.

description: We study a class of two-dimensional ${\cal N}=(0, 4)$ quiver gauge theories that flow to superconformal field theories. We find dualities for the superconformal field theories similar to the 4d ${\cal N}=2$ theories of class ${\cal S}$, labelled by a Riemann surface ${\cal C}$. The dual descriptions arise from various pair-of-pants decompositions, that involves an analog of the $T_N$ theory. Especially, we find the superconformal index of such theories can be written in terms of a topological field theory on ${\cal C}$. We interpret this class of SCFTs as the ones coming from compactifying 6d ${\cal N}=(2, 0)$ theory on $\mathbb{CP}^1 \times {\cal C}$

description: We obtain Koszul-type dualities for categories of graded modules over a graded associative algebra which can be realized as the semidirect product of a bialgebra coinciding with its degree zero part and a graded module algebra for the latter. In particular, this applies to graded representations of the universal enveloping algebra of the Takiff Lie algebra (or the truncated current algebra) and its (super)analogues, and also to semidirect products of quantum groups with braided symmetric and exterior module algebras in case the latter are flat deformations of classical ones.

description: To achieve accurate slug lengths and velocities in a slug flow regime, monitoring of the droplet/bubble train is an essential stage which necessitates the use of proper techniques. In most experiments, the traditional measurement apparatus consists of a high-speed camera coupled to a microscope which are employed to characterize such flows in microchannels. However, when using these techniques, optical distortion caused by the curved channel walls can result in large measurement uncertainty which undermines the measurement accuracy. In this regard, this study introduces a novel technique to easily and reliably measure slug length and velocity. This automated, non-intrusive measurement technique allows for in-line high-frequency droplet/bubble detection and related physical properties based on changes in the light intensity caused by a phase shifting in liquid-liquid or liquid-gas flows.

description: To determine the prevalence of adult refractive error and associated risk factors in the Vientiane Province of the Lao People’s Democratic Republic. Population-based, cross-sectional ophthalmic survey of individuals ≥ 40 years of age in Vientiane Province. Suitable refractive data was available in 1058 individuals. Demographic data, which included age and gender, was obtained from all participants. Smoking status, presence of diabetes and hypertension was also recorded. The ophthalmic examination included autorefraction, grading of cataract, applanation tonometry and ultrasound pachymetry for ocular biometry, including axial length. Mean refractive error measured −0.36 diopters (D) (standard deviation [SD], 1.41) and mean cylindrical error measured −0.33 D (SD 0.95). Myopia ≤ −0.5 D and ≤ −5.0 D occurred in 53.2% (95% confidence interval [CI]: 43.7 to 62.6) and 2.0% (95% CI: 0.4 to 3.6) of participants, respectively. There was a correlation between myopia and both age and higher grading of nuclear cataract (p < .001). Hyperopia ≥ +0.5 D was present in 26.4% of participants and was associated with increasing age (p < .001). Astigmatism was present in 55.8% (95% CI: 51.5 to 60.2) of the population and was associated with increased nuclear cataract (p < .001). Urban participants had a reduced prevalence of myopia compared with rural participants. Myopia was associated with younger age and a higher grade of nuclear cataract. The prevalence of myopia in the adult population of Vientiane Province was higher than that reported in neighbouring Asian regions and contributed to low vision.

description: Aluminum is widely used for space and military applications due to its performance and availability. However,aluminum combustion is complex and not fully understood so far. Aluminum combustion produces aluminum oxide (Al2O3 ) as fine particles (smoke) but this oxide is also present on the burning particle as a distinct cap, or lobe, because liquid aluminum and its oxide are non-miscible. The presence of this oxide lobe on the particle decreases the available surface for aluminum evaporation and is believed to affect combustion times. Moreover,once aluminum has fully burnt out, the lobe remains as a relatively large oxide particle (so-called oxide residue) in the flow. Currently, there is no clear and well-accepted mechanism for this oxide lobe formation and quantitative predictions of lobe growth and final oxide residue are missing. In this work, we investigate the role of thermophoresis as a possible mechanism for the deposition of alumina smoke from the flame to the aluminum particle surface. Thermophoresis is the motion of fine particles due to gradients in temperature. We have performed direct numerical simulations on a single aluminum droplet burning in a quiescent atmosphere and found that thermophoresis is the main mechanism driving smoke back to the particle surface and a major contributor to the oxide lobe development on the particle. The presence of the lobe is found to distort the flow field, and this favors hot and smoke-rich regions closer to the lobe, thereby enhancing thermophoresis. This combination of aerodynamic and thermophoretic effects leads to a mass rate of deposited smoke which is consistent with experimental data. We have then developed a simplified model, deduced from simulation results, which predicts final oxide residues that are quite close to measurements and identifies the initial amount of oxide present on the particle as an important parameter. This study confirms that aluminum oxide present on the burning aluminum particle as a lobe is largely due to material formed in the flame, subsequently deposited by thermophoresis.

description: We study the cross-correlation of distribution of galaxies, the Sunyaev-Zel'dovich (SZ) and X-ray power spectra of galaxies from current and upcoming surveys and show these to be excellent probes of the nature, i.e. extent, evolution and energetics, of the circumgalactic medium (CGM). The SZ-galaxy cross-power spectrum, especially at large multipoles, depends on the steepness of the pressure profile of the CGM. This property of the SZ signal can, thus, be used to constrain the pressure profile of the CGM. The X-ray cross power spectrum also has a similar shape. However, it is much more sensitive to the underlying density profile. We forecast the detectability of the cross-correlated galaxy distribution, SZ and X-ray signals by combining South Pole Telescope-Dark Energy Survey (SPT-DES) and eROSITA-DES/eROSITA-LSST (extended ROentgen Survey with an Imaging Telescope Array-Large Synoptic Survey Telescope) surveys, respectively. We find that, for the SPT-DES survey, the signal-to-noise ratio (SNR) peaks at high mass and redshift with SNR $\sim 9$ around $M_h\sim 10^{13} h^{-1} M_{\odot}$ and $z\sim 1.5\hbox{--} 2$ for flat density and temperature profiles. The SNR peaks at $\sim 6 (12 )$ for the eROSITA-DES (eROSITA-LSST) surveys. We also perform a Fisher matrix analysis to find the constraint on the gas fraction in the CGM in the presence or absence of an unknown redshift evolution of the gas fraction. Finally, we demonstrate that the cross-correlated SZ-galaxy and X-ray-galaxy power spectrum can be used as powerful probes of the CGM energetics and potentially discriminate between different feedback models recently proposed in the literature; for example, one can distinguish a `no active galactic nuclei feedback' scenario from a CGM energized by `fixed-velocity hot winds' at greater than $3σ$.

description: Acute optic neuritis (ON) is variably treated with glucocorticoids. We aimed to describe factors associated with glucocorticoid use. In this retrospective, longitudinal cohort study of insured patients in the United States (2005–2019), adults 18–50 years old with one inpatient or ≥2 outpatient diagnoses of ON within 90 days were included. Glucocorticoid use was classified as none, any dose, and high-dose (>100 mg prednisone equivalent ≥1 days). The primary outcome was glucocorticoid receipt within 90 days of the first ON diagnosis. Multivariable logistic regression models assessed the relationship between glucocorticoid use and sociodemographics, comorbidities, clinician specialty, visit number, and year. Of 3026 people with ON, 65.8% were women (n = 1991), median age (interquartile range) was 38 years (31,44), and 68.6% were white (n = 2075). Glucocorticoids were received by 46% (n = 1385); 54.6% (n = 760/1385) of whom received high-dose. The odds of receiving glucocorticoids were higher among patients with multiple sclerosis (OR 1.61 [95%CI 1.28–2.04]; P < .001), MRI (OR 1.75 [95%CI 1.09–2.80]; P = .02), 3 (OR 1.80 [95%CI 1.46–2.22]; P < .001) or more (OR 4.08 [95%CI 3.37–4.95]; P < .001) outpatient ON visits, and in certain regions. Compared to ophthalmologists, patients diagnosed by neurologists (OR 1.36 [95%CI: 1.10–1.69], p = .005), emergency medicine (OR 3.97 [95%CI: 2.66–5.94]; P < .001) or inpatient clinicians (OR 2.94 [95%CI: 2.22–3.90]; P < .001) had higher odds of receiving glucocorticoids. Use increased 1.1% annually (P < .001). Demyelinating disease, care intensity, setting, region, and clinician type were associated with glucocorticoid use for ON. To optimize care, future studies should explore reasons for ON care variation, and patient/clinician preferences.

description: Supersymmetry searches at the LHC are both highly varied and highly constraining, but the vast majority are focused on cases where the final-stage visible decays are prompt. Scenarios featuring superparticles with detector-scale lifetimes have therefore remained a tantalizing possibility for sub-TeV SUSY, since explicit limits are relatively sparse. Nonetheless, the extremely low backgrounds of the few existing searches for collider-stable and displaced new particles facilitates recastings into powerful long-lived superparticle searches, even for models for which those searches are highly non-optimized. In this paper, we assess the status of such models in the context of baryonic R-parity violation, gauge mediation, and mini-split SUSY. We explore a number of common simplified spectra where hadronic decays can be important, employing recasts of LHC searches that utilize different detector systems and final-state objects. The LSP/NLSP possibilities considered here include generic colored superparticles such as the gluino and light-flavor squarks, as well as the lighter stop and the quasi-degenerate Higgsino multiplet motivated by naturalness. We find that complementary coverage over large swaths of mass and lifetime is achievable by superimposing limits, particularly from CMS's tracker-based displaced dijet search and heavy stable charged particle searches. Adding in prompt searches, we find many cases where a range of sparticle masses is now excluded from zero lifetime to infinite lifetime with no gaps. In other cases, the displaced searches furnish the only extant limits at any lifetime.

description: We present a systematic analysis of the rotation curves of 187 galaxies with masses greater than 10^10 M_sol, with atomic gas masses from the GALEX Arecibo Sloan Survey (GASS), and with follow-up long-slit spectroscopy from the MMT. Our analysis focuses on stellar rotation curves derived by fitting stellar template spectra to the galaxy spectra binned along the slit. In this way, we are able to obtain accurate rotation velocity measurements for a factor of 2 more galaxies than possible with the Halpha line. Galaxies with high atomic gas mass fractions are the most dark-matter dominated galaxies in our sample and have dark matter halo density profiles that are well fit by Navarro, Frenk & White profiles with an average concentration parameter of 10. The inner slopes and of the rotation curves correlate more strongly with stellar population age than with galaxy mass or structural parameters. At fixed stellar mass, the rotation curves of more actively star-forming galaxies have steeper inner slopes than less actively star-forming galaxies. The ratio between the galaxy specific angular momentum and the total specific angular momentum of its dark matter halo, R_j, correlates strongly with galaxy mass, structure and gas content. Low mass, disk-dominated galaxies with atomic gas mass fractions greater than 20% have median values of R_j of around 1, but massive, bulge-dominated galaxies have R_j=0.2-0.3. We argue that these trends can be understood in a picture where gas inflows triggered by disk instabilities lead to the formation of passive, bulge-dominated galaxies with low specific angular momentum.

description: Nitrogen is a key factor limiting primary production in coastal ecosystems. Determining how these systems modulate nitrogen availability is critical. Estuarine environments are heterogeneous, with physical differences such as tidal elevation and sediment characteristics that affect nutrient processing. I used membrane inlet mass spectrometry to measure changes in N2 flux, referred to as denitrification, in a channel and the nearby marsh of a tidal creek through an annual cycle. I will discuss how denitrification rates vary between habitat and the predictive factors that can be used to assess the ecosystem function associated with nitrogen cycling in estuarine sediments.
title: Schools transitioning towards more climate awareness : a multi-level analysis of climate protection projects in the German school system

Subjects: subject: 300 Sozialwissenschaften

description: This thesis conceptualizes the school as a socio-technical system, in which change towards sustainable development and a transition towards more climate awareness are necessary. The multi-level perspective (MLP) framework is applied to the German school system and to climate protection projects (CPPs) as examples of niche activities integrating climate protection (CP) in the school. The thesis utilizes the analytical levels of the MLP (landscape, regime, and niche) and the concept of regulative, cognitive, and normative rules and addresses the question: How do actors in CPPs perceive drivers and barriers for transitioning towards more climate awareness in the German school system? The data were collected through expert interviews and analyzed by conducting a qualitative content analysis. The results show that the German school system is characterized by an inherent rigidity, deep-set normative role dynamics, and an unappreciated role of schools in society. They also highlight the importance of public pressure, strategic CP orientation, and hands-on approaches. CPPs can be a driving force for this in individual schools, but, overall, CP needs to be addressed more systematically in the school and more substantial efforts and reforms are necessary. Highly motivated niche actors play an important role and represent key drivers for such developments. This thesis reveals the complex and systemic nature of the challenges the German school system is faced with. It highlights the difficulties of integrating CP and the importance of substantial and transformative political action. The thesis demonstrates the crucial need to recognize the significance of schools and their actors for society and to integrate new methods and approaches into the school. This thesis also contributes to the body of literature on socio-technical systems and sustainability transitions. It offers an operationalization of the MLP and reveals strengths and limits as well as future research outlooks.

description: We present a numerical method for the computation of the conformal map from unbounded multiply-connected domains onto lemniscatic domains. For $\ell$-times connected domains the method requires solving $\ell$ boundary integral equations with the Neumann kernel. This can be done in $O(\ell^2 n \log n)$ operations, where $n$ is the number of nodes in the discretization of each boundary component of the multiply connected domain. As demonstrated by numerical examples, the method works for domains with close-to-touching boundaries, non-convex boundaries, piecewise smooth boundaries, and for domains of high connectivity.

A vinculin tail hotspot mutation in cancer patients affects mouse embryonic fibroblast motility
Creators: name: Chaddha, Jasleen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Vinculin, an essential adhesion scaffolding protein, physically links membrane bound integrin and cadherin receptors to filamentous actin. Cells that fail to express vinculin or possess dysfunctional vinculin exhibit rounded morphology, enhanced motility, and resistance to apoptosis and anoikis. Therefore, vinculin is classified as a tumor suppressor protein in which mutations have serious consequences in cancer. A possible ‘hotspot’ region—an encoded region of a protein that is highly inclined to mutate and phenotypically manifest—has been identified at in the tail-domain of vinculin at residue R925. At this residue, a specific histidine mutation has been linked to several types of cancer. The purpose of this study was to examine the possibility of residue R925 as a hotspot region and test whether the R925H mutation in vinculin enhances motility properties in a model cell line. To examine the status of R925 as a hotspot region, we mined several databases to link certain prevalent mutations in vinculin to different types of cancer. R925H was the most prominent mutation in vinculin that was present in 5 types of cancer, confirming R925 as a hotspot region. In order to assess whether R925H affected the motility of mouse embryonic fibroblasts (MEFs), actin binding and bundling activity of mutant vinculin was compared to that of wild-type vinculin. We found that R925H mutant vinculin had lower actin bundling ability. To evaluate the changes in motility patterns caused by the introduction of R925H, we conducted random motility assays to measure the two-dimensional migration of MEFs on micro-fabricated and microfluidic devices. Mutant MEFs on hydrogels displayed significant differences in motility compared to wild-type cells—particularly in total accumulated distance, persistence and velocity. However, further investigation is required to interpret these findings. The insight on the effects of the R925H mutation on cell motility will serve as one of the first steps to unravel the complexities of vinculin’s potential role in several human cancer settings.

description: Numerical results for ground state and excited state properties (energies, double occupancies, and Matsubara-axis self energies) of the single-orbital Hubbard model on a two-dimensional square lattice are presented, in order to provide an assessment of our ability to compute accurate results in the thermodynamic limit. Many methods are employed, including auxiliary field quantum Monte Carlo, bare and bold-line diagrammatic Monte Carlo, method of dual fermions, density matrix embedding theory, density matrix renormalization group, dynamical cluster approximation, diffusion Monte Carlo within a fixed node approximation, unrestricted coupled cluster theory, and multi-reference projected Hartree-Fock. Comparison of results obtained by different methods allows for the identification of uncertainties and systematic errors. The importance of extrapolation to converged thermodynamic limit values is emphasized. Cases where agreement between different methods is obtained establish benchmark results that may be useful in the validation of new approaches and the improvement of existing methods.

description: When Industrial Control Systems (ICS) started to be developed, their security was not considered to be a priority, because they were isolated from other networks. Nowadays ICS networks are connected to other networks, even to the internet. Making sure these networks are protected from malicious attacks is an important issue. One of the ways to protect an ICS network is with the use of honeypots. This dissertation describes, at first, the known classifications of honeypots and the communication protocols that are used mostly in ICS networks. Based on the bibliography there are honeypots that can simulate these protocols in various combinations. These honeypots are described and categorized according to certain attributes. Concerning the modern deployment methods, after the reference of all known deployment methods, containerized application deployment is the most time and cost efficient method, according to the bibliography. Kubernetes is a container orchestration system for managing, scaling, and deploying software. And by combining Kubernetes with HoneyChart, we were able to achieve fast and automatic deployment of containerized honeypots.
description: Όταν άρχισαν να αναπτύσσονται τα Συστήματα Βιομηχανικού Ελέγχου (ΣΒΕ), η ασφάλειά τους δεν θεωρούταν προτεραιότητα, επειδή ήταν απομονωμένα από άλλα δίκτυα. Σήμερα τα δίκτυα ΣΒΕ είναι συνδεδεμένα με άλλα δίκτυα, ακόμη και με το διαδίκτυο. Η διασφάλιση της προστασίας αυτών των δικτύων από κακόβουλες επιθέσεις είναι ένα σημαντικό ζήτημα. Ένας από τους τρόπους προστασίας ενός δικτύου ΣΒΕ είναι με τη χρήση honeypots. Η παρούσα εργασία περιγράφει, αρχικά, τις γνωστές κατηγορίες των honeypots και τα πρωτόκολλα επικοινωνίας που χρησιμοποιούνται κυρίως σε δίκτυα ΣΒΕ. Με βάση τη βιβλιογραφία υπάρχουν honeypots που μπορούν να προσομοιώσουν αυτά τα πρωτόκολλα σε διάφορους συνδυασμούς. Αυτά τα honeypots περιγράφονται και κατηγοριοποιούνται σύμφωνα με ορισμένα χαρακτηριστικά. Όσον αφορά τις σύγχρονες μεθόδους ανάπτυξης, μετά την αναφορά όλων των γνωστών μεθόδων ανάπτυξης, η ανάπτυξη εφαρμογών σε μορφή container είναι η πιο αποδοτική μέθοδος από άποψη χρόνου και κόστους, σύμφωνα με τη βιβλιογραφία. Το λογισμικό Kubernetes είναι ένα σύστημα ενορχήστρωσης container για διαχείριση, κλιμάκωση και ανάπτυξη λογισμικού. Και συνδυάζοντας το Kubernetes με το HoneyChart, μπορέσαμε να επιτύχουμε γρήγορη και αυτόματη ανάπτυξη containerized honeypots.

How Can Immigrant Access to Legal Services in North Carolina Be Improved? A Case Study Analysis

description: 	Since North Carolina does not guarantee legal representation for immigrants in immigration proceedings, the fairness of the complex system in the state is questionable. Achieving equitable outcomes requires changes. This thesis aims: 1) To qualitatively evaluate challenges in North Carolina’s immigration system and 2) To provide recommendations for improvement. Twenty-three North Carolina Legal Service Organizations (LSOs) were selected from a national registry and invited to participate in individual Zoom video conferences surveying the immigration legal system in the state. A qualitative case study analysis was carried out using grounded theory to derive improvement suggestions. 14/23 LSOs (60.8%) participated. Zoom transcribed the interviews. The qualitative analysis unearthed the following common themes about challenges in NC’s immigration system: the complexity of the immigration system and law; barriers faced by immigrants; and funding limitations for LSOs. Literature review dovetailed with themes to delineate how to enact and fund representation for immigration proceedings. Three improvement suggestions surfaced. Final reflection revealed three meta-themes: capitalize now on the pro-immigration spirit unleashed by Trump’s harshness; enact, expand, and pay for politically progressive immigration changes, and recognize there is no “silver bullet.”

description: The presence of multiple populations in globular clusters has been well established thanks to high-resolution spectroscopy. It is widely accepted that distinct populations are a consequence of different stellar generations: intra-cluster pollution episodes are required to produce the peculiar chemistry observed in almost all clusters. Unfortunately, the progenitors responsible have left an ambiguous signature and their nature remains unresolved. To constrain the candidate polluters, we have measured lithium and aluminium abundances in more than 180 giants across three systems: NGC~1904, NGC~2808, and NGC~362. The present investigation along with our previous analysis of M12 and M5 affords us the largest database of simultaneous determinations of Li and Al abundances. Our results indicate that Li production has occurred in each of the three clusters. In NGC~362 we detected an M12-like behaviour, with first and second-generation stars sharing very similar Li abundances favouring a progenitor that is able to produce Li, such as AGB stars. Multiple progenitor types are possible in NGC~1904 and NGC~2808, as they possess both an intermediate population comparable in lithium to the first generation stars and also an extreme population, that is enriched in Al but depleted in Li. A simple dilution model fails in reproducing this complex pattern. Finally, the internal Li variation seems to suggest that the production efficiency of this element is a function of the cluster's mass and metallicity - low-mass or relatively metal-rich clusters are more adept at producing Li.

Polyethylene Glycol Size and Protein-Complex Stability
Creators: name: Lauzier, Francis

description: The cellular interior is a crowded and dynamic environment where macromolecules occupy 20% to 30% of the total volume. In such an environment, cytoplasmic components experience soft chemical interactions and hard-core repulsions. These soft interactions can be stabilizing or destabilizing, while hard-core repulsions are only stabilizing. While there have been studies on the effects of the crowded environment on protein stability, few studies exist on protein-protein interactions. To study how protein-protein interactions are affected by crowding, I used polyethylene glycols at a concentration of 200 g/L, a homodimerizing variant of the B1 domain of protein G as my model system, and 19F nuclear magnetic resonance to determine the crowding effects of twelve sizes of PEGs on dimer stability, defined as the free energy of dissociation, ∆𝐺°′D→M. I observed a destabilizing effect with PEGs smaller than 1 kDa, including the monomer, ethylene glycol. PEGs larger than 1 kDa had an increasing stabilizing effect, until leveling off around 8 kDa. Preliminary investigations into the temperature dependence of stability were used to assess the enthalpic contributions. The data suggest that attractive interactions between PEG and the protein are overcome by hard-core repulsions that increase with PEG molecular weight.

description: Massive gravity theories have been developed as viable IR modifications of gravity motivated by dark energy and the problem of the cosmological constant. On the other hand, modified gravity and modified dark matter theories were developed with the aim of solving the problems of standard cold dark matter at galactic scales. Here we propose to adapt the framework of ghost-free massive bigravity theories to reformulate the problem of dark matter at galactic scales. We investigate a promising alternative to dark matter called dipolar dark matter (DDM) in which two different species of dark matter are separately coupled to the two metrics of bigravity and are linked together by an internal vector field. We show that this model successfully reproduces the phenomenology of dark matter at galactic scales (MOND) as a result of a mechanism of gravitational polarisation. The model is safe in the gravitational sector, but because of the particular couplings of the matter fields and vector field to the metrics, a ghost in the decoupling limit is present in the dark matter sector. However, it might be possible to push the mass of the ghost beyond the strong coupling scale by an appropriate choice of the parameters of the model. Crucial questions to address in future work are the exact mass of the ghost, and the cosmological implications of the model.

Evaluating the Feasibility and Potential Impact of a Transitional Care Management Service in an Independent Community Pharmacy + Clinic
Creators: name: Pike, Jefferson
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Introduction: Hospital readmissions are a significant and largely preventable burden on the healthcare system. They can often be prevented with diligent coordination of care and a smooth transition of
patients from hospitalist back to primary care. Transitional care management is a billable service that is designed to reward providers for reducing readmissions. This study assessed the feasibility and
potential impact of a transitional care management service in the setting of an independent community pharmacy and embedded clinic.
Methods: This exploratory mixed-method quality improvement study pursued three aims: (1) describe the current landscape of transitional care services in the literature based on an informal environmental
scan; (2) adapt and improve the baseline transitional care service in Hillsborough Pharmacy to align with billing requirements for billing as guided by the intervention mapping methodology; and (3) establish the feasibility of the transitional care service in the pharmacy setting by conducting interviews with pharmacists considering a partnership with the clinic franchise company (IndyCare). Results: The environmental scan found 26 transitional care studies in community pharmacy settings. Feedback on service implementation was abstracted from the studies and used to identify best practices, facilitators, and barriers to program implementation. Key insights included the need for buy-in
from external stakeholders to enable patient data sharing, and careful planning to ensure satisfactory patient enrollment in the service. These insights were used to improve the transitional care service
through iterative intervention mapping in order to identify desired outcomes and revise the clinic’s processes to achieve them in the context of anticipated facilitators and barriers. This process enabled
the clinic to achieve full alignment with billing requirements. Interview feedback from future partners was generally positive, with interviewees expressing an intent to partner in providing transitional care
management. Conclusions: The independent pharmacy + clinic is a viable practice setting for implementing a transitional care management program, provided careful planning and awareness of best practices.
While having in-house providers allows for more autonomy, collaboration with external providers is still a vital component for numerous reasons, including notification of recent discharges and shared patient data. Given its collaborative nature, transitional care management is a good service for initiating collaborative partnerships with external healthcare professionals.
