description: Analogues of the frequentist chi-square and F tests are proposed for testing goodness-of-fit and consistency for Bayesian models. Simple examples exhibit these tests' detection of inconsistency between consecutive experiments with identical parameters, when the first experiment provides the prior for the second. In a related analysis, a quantitative measure is derived for judging the degree of tension between two different experiments with partially overlapping parameter vectors.

description: We introduce a new class of generalized isotropic Lipkin-Meshkov-Glick models with su$(m+1)$ spin and long-range non-constant interactions, whose non-degenerate ground state is a Dicke state of su$(m+1)$ type. We evaluate in closed form the reduced density matrix of a block of $L$ spins when the whole system is in its ground state, and study the corresponding von Neumann and Rényi entanglement entropies in the thermodynamic limit. We show that both of these entropies scale as $a\log L$ when $L$ tends to infinity, where the coefficient $a$ is equal to $(m-k)/2$ in the ground state phase with $k$ vanishing su$(m+1)$ magnon densities. In particular, our results show that none of these generalized Lipkin-Meshkov-Glick models are critical, since when $L\to\infty$ their Rényi entropy $R_q$ becomes independent of the parameter $q$. We have also computed the Tsallis entanglement entropy of the ground state of these generalized su$(m+1)$ Lipkin-Meshkov-Glick models, finding that it can be made extensive by an appropriate choice of its parameter only when $m-k\ge3$. Finally, in the su$(3)$ case we construct in detail the phase diagram of the ground state in parameter space, showing that it is determined in a simple way by the weights of the fundamental representation of su$(3)$. This is also true in the su$(m+1)$ case; for instance, we prove that the region for which all the magnon densities are non-vanishing is an $(m+1)$-simplex in $\mathbf R^m$ whose vertices are the weights of the fundamental representation of su$(m+1)$.

Narcissistic Abuse Is a Dark Spiritual Experience

description: Spirituality has become a word of controversy in the field of Psychology. Some psychologists argue that spiritual beliefs can become a distorted, non-realistic transference of what needs to be seen ideal within. Words like intrapsychic trauma, empathy, vulnerability and narcissism are parameters of our daily lives whether we realize it or not.  It is proposed that spirituality, being a process by which one recognizes the self as part of the whole, whole being something greater than the self, has a reverse relationship to narcissism. More specifically, narcissism can be seen as a dark place of spirituality.  Lack of empathy is the point of differentiation for diagnosed narcissistic personalities. Spirituality is a place of the heart where empathy is highly promoted needed and emphasized. In addition, being vulnerable willingly, is the gatekeeper of psychotherapy. Narcissism on the other hand, is a state of non-vulnerability. Narcissists do not wish to be submitted to therapeutic pain, as it threatens their pseudo-strength and persona.  It is spirituality through which, we always need to keep an anchor inside, always reminding ourselves that all fundamental truth of ourselves lies within us. It is worth examining how it is related to all other psychological forms of our existence.

Keeping it green: a study of open space conservation efforts in the Triangle
Creators: name: Hebert, Katherine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: This is the first report of its kind in the Triangle Region defined as Wake, Durham, Orange, Chatham, Lee, and Johnston counties in central North Carolina. Although there have been regional open space planning efforts in the past- most markedly the GreenPrint of 2002 and the State of Open Space Reports in 2000 and 2002- this is the first report that combines GIS mapping and analysis with interviews of key stakeholders and a review of plans relevant to open space protection. Thanks to advancements in mapping software and the management of parcel information and land acquisition by each county within the region, a more accurate and comprehensive map of conservation lands is now possible. The availability and accuracy of maps displaying the latest information on conservation lands and easements will play a critical role in the region's ability to conduct open space planning on regional projects. The major finding of this report is that the calculated acreage of conserved lands according to GIS analysis is greatly below the acreage of conserved lands being reported by the different municipalities, non-profit organizations, and federal or state agencies. When the conservation lands and conservation easement shapefiles of the One NC Naturally planning tool were merged, clipped by county boundaries, and dissolved to form one layer with no duplicated properties, the total acreage of land conserved within the Triangle as of July 2009 was 155,499 acres. This is actually about 200 acres less than what was reported in the 2002 State of Open Space Report (Costa, 2002). If progress has been made in land conservation within the Triangle how is this possible? There are a couple of explanations for these findings. In some cases, especially with the larger management areas such as those surrounding Jordan Lake or Falls Lake, the same property had multiple property owners each reporting part or all of the property. While this is a good indicator that regional partnerships are occurring, it also leads to an overestimation of the actual land that is being protected through conservation measures such as fee simple purchase or conservation easements. Another possible explanation is the definition of what is being considered open space is different from one report to the next. For example, the 2002 State of Open Space Report includes corporate lands while the category of corporate lands was not included within the One NC Naturally database (Costa, 2002).

description: A geometric formulation of Higgs Effective Field Theory (HEFT) is presented. Experimental observables are given in terms of geometric invariants of the scalar sigma model sector such as the curvature of the scalar field manifold $\mathcal M$. We show how the curvature can be measured experimentally via Higgs cross-sections, $W_L$ scattering, and the $S$ parameter. The one-loop action of HEFT is given in terms of geometric invariants of $\mathcal M$. The distinction between the Standard Model (SM) and HEFT is whether $\mathcal M$ is flat or curved, not whether the scalars transform linearly or non-linearly under the electroweak group.
description: Journal version. The introduction has been rewritten to make clearer the distinction between SM, SMEFT and HEFT. A slight change of notation has been introduced to connect observables with sectional curvature
A hard X-ray view of the soft excess in AGN

description: An excess of X-ray emission below 1 keV, called soft excess, is detected in a large fraction of Seyfert 1-1.5s. The origin of this feature remains debated, as several models have been suggested to explain it, including warm Comptonization and blurred ionized reflection. In order to constrain the origin of this component, we exploit the different behaviors of these models above 10 keV. Ionized reflection covers a broad energy range, from the soft X-rays to the hard X-rays, while Comptonization drops very quickly in the soft X-rays. We present here the results of a study done on 102 Seyfert 1s (Sy 1.0, 1.2, 1.5 and NLSy1) from the Swift/BAT 70-Month Hard X-ray Survey catalog. The joint spectral analysis of Swift/BAT and XMM-Newton data allows a hard X-ray view of the soft excess that is present in about 80% of the objects of our sample. We discuss how the soft-excess strength is linked to the reflection at high energy, to the photon index of the primary continuum and to the Eddington ratio. In particular, we find a positive dependence of the soft-excess intensity on the Eddington ratio. We compare our results to simulations of blurred ionized-reflection models and show that they are in contradiction. By stacking both XMM-Newton and Swift/BAT spectra per soft-excess strength, we see that the shape of reflection at hard X-rays stays constant when the soft excess varies, showing an absence of link between reflection and soft excess. We conclude that the ionized-reflection model as the origin of the soft excess is disadvantaged in favor of the warm Comptonization model in our sample of Seyfert 1s.

Neighborhood design and body mass: Does weight status differ between a new urbanist and conventional suburban neighborhoods?
Creators: name: Brown, Austin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005
Subjects: New urbanisms
Body mass index

description: Background: The increasing prevalence of overweight and obesity is a public health concern in the United States. There is a small but growing body of literature examining the relationship between neighborhood level characteristics, physical activity and weight status. However, to date, none of theses studies have examined the association between new urbanist communities and weight status. Objective: To examine the prevalence of overweight, obesity and body mass index of household heads in a new urbanist neighborhood relative to household heads of comparable conventional suburban neighborhoods. Method: Using a quasi-experimental design, a new urbanist neighborhood and five conventional suburban neighborhoods in central North Carolina were matched on age of development, assessed property values and regional accessibility. Self-reported height, weight, physical activity and travel behaviors were derived through a questionnaire and travel diary mailed to the heads of household in each neighborhood type between March and May 2003. Results: No significant difference was detected in BMI, overweight and obese prevalence, or moderate and vigorous physical activity levels between household heads in the new urbanist neighborhood and the conventional suburban neighborhoods after controlling for sociodemographic characteristics. However, the study found that new urbanist heads of household made more in-neighborhood utilitarian trips by walking or bicycling than their conventional suburban counterparts and these physical activity trips were related to lower BMI. Conclusion: By offering an environment supportive of non- motorized travel and mixed land uses, household heads of the new urbanist neighborhood integrated walking and biking into their utilitarian trip making. The utilitarian physical activity trips were associated with a lower BMI, however, yet residing in the new urbanist neighborhood was not related to lowering BMI or decreased likelihood of being overweight and obese.

description: A collective, macroscopic signature to detect radiation friction in laser-plasma experiments is proposed. In the interaction of superintense circularly polarized laser pulses with high density targets, the effective dissipation due to radiative losses allows the absorption of electromagnetic angular momentum, which in turn leads to the generation of a quasistatic axial magnetic field. This peculiar "inverse Faraday effect" is investigated by analytical modeling and three-dimensional simulations, showing that multi-gigagauss magnetic fields may be generated at laser intensities $>10^{23}~\mbox{W cm}^{-2}$.

Is the Population Census Useful to Understand the Pedestrian Friendliness of the Built Environment? An Empirical Examination in Portland
Creators: name: Young, Hannah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: This study proposes a built environment index (BEI) that is useful to researchers assessing the quality of the built environment on factors related to walking, bicycling, and transit use. The BEI is an accessible tool because it utilizes readily available U.S. Population Census data and employs a simplified GIS analysis. The index has numerous applications in studies related to health, mode choice, and land use policy. Similar indices have been used in travel models to enhance model accuracy and for the targeting of priority funding areas for cost-effective infrastructure investment. In this study we review previous research utilizing similar indices to examine the types of variables that ought to be included in the index. We compare three different methods for calculating the BEI and conclude that two methods are particularly robust. We then offer a comparison of the BEI with the well-studied pedestrian environment factor (PEF) from Portland. This comparison, however, is tenuous and suggests that though there may be similar uses of the indices, they capture different concepts. We conclude that the BEI is a powerful tool to gain a broad overview of the built environment. It is flexible to manipulation and can be tailored for specific research questions as well as supplemented with more fine-grained approaches where a neighborhood scale analysis is required.

description: We obtain the non-equilibrium effective action of an inflaton like scalar field --the system-- by tracing over sub Hubble degrees of freedom of "environmental" light scalar fields. The effective action is stochastic leading to effective Langevin equations of motion for the fluctuations of the inflaton-like field, with self-energy corrections and stochastic noise correlators that obey a de Sitter space-time analog of a fluctuation dissipation relation. We solve the Langevin equation implementing a dynamical renormalization group resummation of the leading secular terms and obtain the corrections to the power spectrum of super Hubble fluctuations of the inflaton field, $\mathcal{P}(k;η) = \mathcal{P}_0(k)\,e^{-γ(k;η)}$ where $\mathcal{P}_0(k)$ is the nearly scale invariant power spectrum in absence of coupling. $γ(k;η)>0$ describes the suppression of the power spectrum, it features Sudakov-type double logarithms and entails violations of scale invariance. We also obtain the effective action for the case of a heavy scalar field of mass $ M \gg H$, this case yields a local "Fermi" limit with a very weak self-interaction of the inflaton-like field and dissipative terms that are suppressed by powers of $H/M$. We conjecture on the possibility that the large scale anomalies in the CMB may originate in dissipative processes from inflaton coupling to sub-Hubble degrees of freedom.

Defining the "Tipping Point" for Downtown Rocky Mount
Creators: name: Parker, Maggie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Rocky Mount, North Carolina continues to embrace its motto as “a city on the rise.” In particular, the city has sought to redevelop its historic downtown given the decline of businesses and residents over several decades. Since Hurricane Floyd devastated many community assets in 1999, the City of Rocky Mount has initiated and implemented local public sector investments for the redevelopment of historic properties using federal and state resources to incite development. The development of the Douglas Block and Streetscape renovations, more recently, have signaled a belief in the potential redevelopment of downtown Rocky Mount. However, investment from the public sector, in the long-term, is an unsustainable strategy to pursuing economic development for all of the city center. Rather, public investment should incite private-sector interest.
From my previous work in Rocky Mount, it is evident that single-site strategies for market-rate development are not feasible in Rocky Mount’s downtown region. When the private-sector has been involved, 1-2 parcels are purchased but do not demonstrate a change in the market that would prompt additional interest. As a result, an alternative model for provoking real estate development is warranted. This Masters Project assesses the viability of redevelopment of select properties in downtown Rocky Mount, NC as a catalyst for economic development. The analysis attempts to identify the critical mass, or scale of acquisition and operation, needed to make private investment feasible through an acquisition fund. Two case studies on the downtown development trends in Durham, NC and Richmond, VA inform the redevelopment strategy. Implementation of an acquisition fund will spur the process for comprehensively changing the market dynamics, as a “tipping point” for real estate and economic development.
To address this statement, the following report will be separated into three sections that provide the context for the strategy, review case studies, and offer recommendations based on an original financial model. Part 1 will provide context for the strategy by detailing the background on the project and project area; situating the acquisition fund model in literature on downtown redevelopment; and describing the current market for development in Rocky Mount. Part 2 will review case studies in peer cities that influence the assumptions within the acquisition model. Part 3 will provide an overview of the financial model and provide recommendations on using the acquisition fund as a tool for future development.

Can town and country both be green? A comparative study of green building programs and policies in urban and fast-growing rural counties in North Carolina
Creators: name: Van Schaack, Chandler Grant
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Interest in green building has exploded in recent years due to a number of factors. Evidence of global climate change, national security issues relating to dependence on foreign oil, and an economic recession have all helped spur policy makers in the direction of energy efficiency and renewable energy use. While the federal government has enacted a few policies that address green building, the main impetus for addressing energy efficiency in buildings has come from state and local governments. Many state governments, including North Carolina, have adopted legislation meant to promote green building through the use of various financial incentives. Within North Carolina there have been a number of counties and municipalities have adopted policies meant to promote green building as well. "Green public facility" requirements, financial incentives, and permit streamlining have all been ways that local governments have tried to encourage green building practices in North Carolina. The majority of green building policies in place are in urban areas such as Raleigh, Durham, Asheville and Winston-Salem; the vast majority of rural counties and municipalities in the state, which are home to nearly half of the state's residents (NC Rural Center, 2009), do not have any such policies in place. With much of the population growth in the coming decades expected to occur in presently rural areas close to major urban centers (Ibid), building and energy policies in these areas will likely play an increasingly important role in the state's efforts to address global climate change. The purpose of this study is to determine how green building practices can effectively be incorporated into local development policies in fast-growing rural areas that are close to urban centers so as to reduce the environmental impacts of current and future development in 2 these areas. Through a series of five exploratory case studies involving in-depth program analysis and a series of interviews, this study examines 1) why there has been a relative lack of green building initiatives in rural versus urban areas; 2) how different stakeholders influence the adoption and implementation of green building policies; and 3) which policies or programs can most effectively promote green building in fast-growing rural areas. Understanding some of the common constraints to green building and determining ways to effectively promote green building at the local level can provide a tool for local governments to proactively address global climate change and other environmental and economic issues related to rapid growth and development.

description: We calculate the rate of production of hypothetical light vector bosons (LVBs) from nucleon-nucleon bremsstrahlung reactions in the soft radiation limit directly in terms of the measured nucleon-nucleon elastic cross sections. We use these results and the observation of neutrinos from supernova SN1987a to deduce constraints on the couplings of vector bosons with masses $\lesssim 200$ MeV to either electric charge (dark photons) or to baryon number. We establish for the first time strong constraints on LVB that couple only to baryon number, and revise earlier constraints on the dark photon. For the latter, we find that the excluded region of parameter space is diminished by about a factor of 10.

Developing a solar energy potential map for Chapel Hill, NC
Creators: name: Leitelt, Lyle Robert
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Throughout the country, municipalities are mitigating climate change by following the concept of sustainability and promoting themselves as "green" communities. A combination of state incentives and renewable portfolio standards has encouraged the growth of efficient, renewable energy in some communities (US DOE, 2009a). Many cities are looking at ways to decrease emissions and make their communities as carbon neutral as possible. In turn, energy conservation is becoming a bigger issue in the realm of planning. There are several initiatives and projects that cities are promoting, most of which utilize renewable energy, including the installation of solar energy systems throughout the existing urban framework. Local governments are attempting to make solar energy more accessible and affordable for homeowners and businesses (Herbst, 2009). One of the most innovative methods in helping communities with solar energy system installation is to provide a solar energy rooftop potential map. This project is intended to create a solar energy potential map for the Town of Chapel Hill to help with their sustainability efforts. The map's outcome shows the photovoltaic (PV) solar potential for every structure within Chapel Hill. By using raw unprocessed LiDAR data, digital elevation model (DEM) data, town created GIS layers, and GIS spatial analyst tools, every structure's solar area rooftop potential can be determined. Once this base solar rooftop potential is calculated, suitable areas for solar panels can be determined through adequate solar insolation and system cost efficiency. These suitable areas can provide several benefits: the energy savings potential; the installation costs and long term monetary savings (including rebates); and the carbon emissions savings. The calculations of this project are beneficial to several groups including the town's government, homeowners and business owners, and the general public. This project is concurrent with many of the sustainability-focused initiatives that Chapel Hill is committed to and will enhance the town's efforts for energy efficiency.

description: The 3-uniform tight cycle $C_s^3$ has vertex set $ Z_s$ and edge set $\{\{i, i+1, i+2\}: i \in Z_s\}$. We prove that for every $s \not\equiv 0$ (mod 3) and $s \ge 16$ or $s \in \{8,11,14\}$ there is a $c_s>0$ such that the 3-uniform hypergraph Ramsey number $$r(C_s^3, K_n^3)< 2^{c_s n \log n}$$ This answers in strong form a question of the author and Rödl who asked for an upper bound of the form $2^{n^{1+ε_s}}$ for each fixed $s \ge 4$, where $ε_s \rightarrow 0$ as $s \rightarrow \infty$ and $n$ is sufficiently large. The result is nearly tight as the lower bound is known to be exponential in $n$.

description: Background. This paper utilizes a longitudinal dataset, with which we have a great deal of familiarity. We have analyzed portions of the dataset, and have engaged in extensive coding of the narratives. Thus, we detail here what we have done, and what we expect, but this is not a fully pre-registered paper, given our prior knowledge of the dataset. We also refer the reader to the overall OSF page for the project, and the grant proposal, which includes many of our hypotheses prior to data collection. Notably the narrative and codes and survey measures employed in the present study have not been used in any other analyses from this project.
Bringing a rail station back to Hillsborough: an analysis of the process

description: In recent years, increasingly congested roads and airports have led Americans to seek new ways to travel. This parallels with a growing concern over environmental issues and increasing evidence that auto-oriented, large lot, suburban sprawl is not a sustainable lifestyle. An increasing number of people have begun to look forward to the possibilities presented by one of the oldest transportation modes--passenger rail. The United States once had a peerless national network of high-quality, fast, and frequent trains serving the nation's population. Passengers could travel most anywhere in the country on a train, whether the destination was a major city, a small town, or a wilderness resort. Passenger rail, however, declined as transportation priorities shifted after World War II in favor of automobiles and airlines to the point where currently passenger rail barely registers as a blip in national modal choice. Hillsborough, NC actually mirrors this national rail story quite well. Like the rest of the country, rail was instrumental to the early development and economic success of the Town. Further, rail provided the necessary linkages to national locations to keep the Town from being isolated. However, with the growth in importance of autos and roads, passenger rail ridership declined precipitously in Hillsborough and eventually disappeared in 1964. However, prompted by the continued presence of passenger trains on the rail corridor serving the town, economic and energy crises, and current residents who use passenger rail services (embarking from neighboring towns' stations), Hillsborough has begun a process to bring a rail station back to the Town. Prompted by community members, town leaders formed a Rail Station Task Force to study the feasibility of a rail station and then to select the site in town best-suited for rail service; the Task Force eventually selected the Collins Tract, a town-owned parcel near the historic downtown. A second Task-Force (still ongoing as of this writing) has neared completion of a conceptual land-use plan for the site. This paper seeks to analyze the process of bringing a rail station back to Hillsborough to determine whether it has been successful and, to the extent possible, what factors have contributed to that success. In general the process seems to have been a success, although it has been hampered by some problems, such as a lack of funding an occasional sluggishness in process. Factors that have contributed to this success include the competency of the Task Forces, good public support, existing institutional support, leadership from the community, and the political window opened up by the energy crisis and four dollar per gallon gasoline.

description: Identifying and characterizing flame fronts is the most common task in the computer-assisted analysis of data obtained from imaging techniques such as planar laser-induced fluorescence (PLIF), laser Rayleigh scattering (LRS), or particle imaging velocimetry (PIV). We present a novel edge and ridge (line) detection algorithm based on complex-valued wavelet-like analyzing functions -- so-called complex shearlets -- displaying several traits useful for the extraction of flame fronts. In addition to providing a unified approach to the detection of edges and ridges, our method inherently yields estimates of local tangent orientations and local curvatures. To examine the applicability for high-frequency recordings of combustion processes, the algorithm is applied to mock images distorted with varying degrees of noise and real-world PLIF images of both OH and CH radicals. Furthermore, we compare the performance of the newly proposed complex shearlet-based measure to well-established edge and ridge detection techniques such as the Canny edge detector, another shearlet-based edge detector, and the phase congruency measure.
Town of Chapel Hill greenhouse gas emissions inventory municipal operations: 2005 through 2009

description: The scientific evidence of climate change is now well established and necessitates immediate local and global action. This inventory represents the most assertive carbon reduction action yet by the Town of Chapel Hill. Inventorying is where the rubber meets the road in reducing our carbon footprint. Pledges, promises, and plans garner much attention, but inventories are the direction-setters of policy. In order to successfully manage greenhouse gases, it is imperative that emissions are accurately measured. A high-quality inventory indentifies all emission sources, can inform decision makers, and will monitor reduction progress. In many ways an inventory is like a road map: the carbon landscape is revealed, different paths to reduction are identified, and decisions now come with a sense of security provided by a detailed map. Enter this report: the first comprehensive greenhouse gas inventory of municipal operations for the Town of Chapel Hill. It covers the past five calendar years from 2005 to 2009, reported annually, and now gives the town full confidence to move forward. As the first exhaustive inventory conducted for the municipal operations of the Town of Chapel Hill, this report is intended to be a solid foundation for all future town greenhouse gas inventories. Detailed explanations are offered on an array of topics from the current scientific knowledge of climate change to the intricacies of carbon accounting to the methodology of each step. This detail is further necessitated by the fact that this report includes the 2005 baseline, which will likely be referenced by all future reduction targets. Climate change, though a global issue, is still a local matter. Local governments take out the trash, turn on the streetlights, provide transportation service, and shape the character of future growth. And across America it's cities that are at the forefront of climate change action. More and more local governments are responding to climate change in two ways: 1) mitigating the effects of climate change by reducing greenhouse gas emissions at the local level and 2) planning to adapt to some of the expected changes. This document speaks to the first action item: stopping the bleeding. It is the author's hope that this inventory, as an informational item, will help guide the early steps necessary to a carbon-reduced future in Chapel Hill and be an aide to all future carbon-related actions. And for the world's sake, hopefully there are many such actions.
Exploring source region of 3-min slow magnetoacoustic waves observed in coronal fan loops rooted in sunspot umbra

description: Sunspots host various oscillations and wave phenomena like umbral flashes, umbral oscillations, running penumbral waves, and coronal waves. All fan loops rooted in sunspot umbra constantly show a 3-min period propagating slow magnetoacoustic waves in the corona. However, their origin in the lower atmosphere is still unclear. In this work, we studied these oscillations in detail along a clean fan loop system rooted in active region AR12553 for a duration of 4-hour on June 16, 2016 observed by Interface Region Imaging Spectrograph (IRIS) and Solar Dynamics Observatory (SDO). We traced foot-points of several fan loops by identifying their locations at different atmospheric heights from the corona to the photosphere. We found presence of 3-min oscillations at foot-points of all the loops and at all atmospheric heights. We further traced origin of these waves by utilising their amplitude modulation characteristics while propagating in the solar atmosphere. We found several amplitude modulation periods in the range of 9-14 min, 20-24 min, and 30-40 min of these 3-min waves at all heights. Based on our findings, we interpret that 3-min slow magnetoacoustic waves propagating in coronal fan loops are driven by 3-min oscillations observed at the photospheric foot-points of these fan loops in the umbral region. We also explored any connection between 3-min and 5-min oscillations observed at the photospheric foot-points of these loops and found them to be weakly coupled. Results provide clear evidence of magnetic coupling of the solar atmosphere through propagation of 3-min waves along fan loops at different atmospheric heights.

Subjects: subject: Medicine and Health Sciences

description: Background: Antimicrobial resistance (AMR) remains a major health concern globally and is estimated to be responsible for 700,000 deaths per year worldwide. Although immunisation has been shown to significantly reduce AMR, the role of vaccines as part of antimicrobial stewardship (AMS) practices is often overlooked. Objective: The review aims to identify and examine the available literature on the role of vaccines as part of AMS practices. Method: A scoping review will be conducted of seven electronic databases of peer-reviewed articles (MEDLINE, Embase, Scopus, CINAHL, Cochrane Central Register of Controlled Trials, IPA, and Web of Science) and grey literature. The review will be conducted in accordance with the JBI Methodology for Scoping Reviews and reported in line with the PRISMA-SCr checklist.
