APPLYING SOURCE MODELS TO PREDICT DRIVING MECHANISMS OF QUASI-PERIODIC TREMOR
Creators: name: Traphagan, Julian Watanabe
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Modeling harmonic tremor recorded at volcanoes is an essential practice in improving eruption forecasting methods and warning systems. We model the conduit dynamics of quasi-periodic tremor (chugging) recorded at Karymsky, Tungurahua, and Fuego volcanoes to estimate its source characteristics. Chugging mechanisms are estimated using two theoretical models originally derived in Garces (1997) and Girona et al. (2019), respectively. Comparisons of the conduit and fluid output parameters suggests that chugging is primarily limited to near-surface oscillations and outgassing due to an accumulation of gas between eruptive episodes. The modeled results indicate clustered release of volatiles exsolved from a deeper magma conduit region, triggered by an initial explosion. This interpretation is consistent with both infrasonic and seismic observations at each volcano.

description: We analyze spectral properties of a leaky wire model with a potential bias. It describes a two-dimensional quantum particle exposed to a potential consisting of two parts. One is an attractive $δ$-interaction supported by a non-straight, piecewise smooth curve $\mathcal{L}$ dividing the plane into two regions of which one, the `interior', is convex. The other interaction component is a constant positive potential $V_0$ in one of the regions. We show that in the critical case, $V_0=α^2$, the discrete spectrum is non-void if and only if the bias is supported in the interior. We also analyze the non-critical situations, in particular, we show that in the subcritical case, $V_0

title: Metal Rim Smartphone Antennas for 5G Communications
Creators: name: Chen, Lyuwei
Publisher: name: University of Liverpool Repository
Year: 2025

description: The advent of 5G has presented new challenges and opportunities for smartphone antenna design. With more frequency bands and higher speed requirements, antenna engineers face the task of achieving comprehensive coverage and faster data transmission in smaller smartphone volumes. Additionally, users' demands for network speed and connection quality have increased, necessitating higher-performing and more stable antenna designs. Despite these challenges, antenna engineers can meet market needs through innovation and design optimization. Furthermore, as 5G ushers in a wider range of services, improving the channel capacity of mobile phones is crucial. MIMO technology offers an effective solution by enhancing channel capacity and spectral efficiency. However, integrating numerous antennas into mobile phones restricts space for 5G MIMO arrays, leading to difficulties in achieving isolation and minimizing interference. Moreover, the human body's presence can significantly impact mobile phone antenna performance. Human tissue absorbs and reflects wireless signals, resulting in signal loss and increased interference, ultimately affecting communication quality and user experience. Therefore, studying the influence of the human body on mobile phone antennas can drive better antenna designs and optimize performance, enhancing smartphone communication quality.

Building and Maintaining Trust in Small, Rural Northern Alberta Schools
Creators: Jessica Whelan
Publisher: name: University of Alberta Library
Year: 2022

Building trust is essential for rural schools to succeed. Relationships based on trust increase communication and decision-making which positively affect school functioning. Trust in relationships is not static, therefore, it takes effort to build and sustain that trust, which is a slow and deliberate process. Trust is fragile and can, if not sustained, break down over time. It can be broken not only by intentional acts, but by unintentional ones as well. Both sides must feel there is a benefit to rebuilding the relationship in order to make the effort to do so. The overall purpose of this study was to gain an

understanding of how principals in small, rural Northern Alberta schools build and maintain trust with their staffs. A qualitative interview model, drawing on aspects of a grounded theory research paradigm combined with a critical praxis research approach, was used to gain an in-depth description of respondents’ views. The analysis of three case studies of principals of small, rural Northern Alberta schools, found principals must act with benevolence, vulnerability, reliability, and competence to build trust. Small, rural school principals must be aware the culture of trust they create with their staff can be affected by the larger community, therefore, they must gain a thorough understanding of the context of their community if they wish to be successful leaders. When trust is perceived as having been broken, it takes time and commitment to restore it.

Year: 2020

description: This study assessed characteristics of parents and their children associated with parent awareness of AT-implemented injury prevention strategies, and parent trust in AT medical knowledge. A cross-sectional self-administered questionnaire was distributed to parents of high school athletes from one central North Carolina school district during fall and winter sport preseason parent meetings. Parents exhibited moderate awareness of both AT-implemented injury prevention strategies (median score=14, IQR 12-16, possible range: 0-17) and trust in AT medical knowledge (median score=55, IQR 51-59, possible range: 14-70). High trust in AT medical knowledge was associated with high awareness of AT-implemented injury prevention strategies (OR=2.32, 95% CI: 1.15-4.67) and previous experience interacting with an AT for one’s own injury (OR=2.30, 95% CI: 1.08-4.88). An increased awareness of AT-implemented injury prevention strategies score and experience interacting with an AT for ones’ own injury were associated with higher trust in AT medical knowledge.
title: Factors affecting de novo formation of a yeast prion
Creators: name: Stojanovski, Klement
Publisher: name: University of Kent
Year: 2022

description: Prions are aggregates of misfolded proteins that have acquired an amyloid-like structure and ability to propagate through recruitment of new proteins. [PSI+], a prion form of eukaryotic release factor Sup35 (eRF1) is widely used as a model for research on prion formation and propagation and in this study [PSI+] is used to explore an effect of three previously identified proteins on de novo prion formation. One mechanism proposed to affect prion formation is direct interaction of Sup35p with its binding partners and search for proteins that interact with Sup35p identified Ppq 1 p, a putative Ser/Thr protein phosphatase (M.F. Tuite and T. von der Haar). Another approach was to identify proteins that function to protect translational apparatus from environmental and . endogenous oxidative damage. and this approach identified two ribosome associated peroxiredoxins, Tsa1 p and Tsa2p (T. Sideri and C.M. Grant). The data presented here shows that the deletion of PPQ1 gene greatly increases the rate of de novo formation of [PSI+] but the mechanism by which loss of Ppq1 p affects [PSI+] formation is not known. Analysis of the distribution of fluorescently-tagged Ppq 1 P showed that the protein co-localises with mitochondria. A further line of evidence linking Ppq 1 P to mitochondria was an observed reduction in respiratory capacity of a ppq1 Δ strain. That exposure to environmental sources of oxidative stress promotes [PSI+] prion formation was previously reported (Tyedmers et al., 2008). Results presented here show that an endogenous source of oxidative stress, brought about by deleting the ribosomally- associated peroxiredoxins (Prx) encoded by genes TSA 1/2 (Trotter et al., 2008; Sideri et al., 2010), also increases the rate of de novo [PSI+]formation. This result provides a direct link between oxidative stress and the eukaryotic release factor Sup35p.

description: We perform model searches on smooth Calabi-Yau compactifications for both the supersymmetric E8xE8 and SO(32) as well as for the non-supersymmetric SO(16)xSO(16) heterotic strings simultaneously. We consider line bundle backgrounds on both favorable CICYs with relatively small h_11 and the Schoen manifold. Using Gram matrices we systematically analyze the combined consequences of the Bianchi identities and the tree-level Donaldson-Uhlenbeck-Yau equations inside the Kahler cone. In order to evaluate the model building potential of the three heterotic theories on the various geometries, we perform computer-aided scans. We have generated a large number of GUT-like models (up to over a few hundred thousand on the various geometries for the three heterotic theories) which become (MS)SM-like upon using a freely acting Wilson line. For all three heterotic theories we present tables and figures summarizing the potentially phenomenologically interesting models which were obtained during our model scans.

Distinct Indiscernibles and the Nature of Identity
Creators: name: Thornton, Zach
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: There exists indiscernibles, entities that are numerically distinct but share all their qualitative properties. The existence of indiscernibles raises a problem for Leibniz's Law, the longstanding standard account of the nature of identity and distinctness which states that entities are identical if and only if they are qualitatively indiscernible, and distinct otherwise. In this paper, I aim to propose an alternative account to Leibniz's Law that explains the distinctness of indiscernibles. My proposal, which I will call the Modal Independence proposal, states that the distinctness of indiscernibles is explained by the fact that they are possibly discernible. While indiscernibles share all their qualitative properties in the world they reside, there are worlds where they do not. At some worlds, the entities are discernible, and this is what makes them distinct.
UNDERSTANDING FACTORS INFLUENCING YOUNG ORTHODONTIST CAREER DECISIONS
Creators: name: Campbell, Catherine

Year: 2020

description: Orthodontic graduates in the United States are choosing associateships over ownership as their initial employment. Less than one-third of recent graduates pursue ownership today, compared to 62% in 2010. The job market of orthodontics is being reshaped by high student debt, growth of corporate dentistry, changing gender demographics, and evolving consumer behaviors. Through qualitative interviews, and a national survey, we aim to identify factors influencing orthodontist career trajectories, and to evaluate how early career choices influence job satisfaction. Twenty-five orthodontic residents and practicing orthodontists were interviewed in a semi-structured format. Interview transcripts were analyzed to identify factors influencing career decisions and job satisfaction. Thematic patterns were established through iterative systematic analysis. To test generalizability of our qualitative results, we developed and distributed a national survey to AAO members via the Partners in Research Program. Data were assessed using descriptive and bivariate analyses. Survey response reveals increased student debt, need for income, and desire for work-life balance are influencing the decision of orthodontic residents to pursue employment options rather than ownership. Orthodontic residents maintain long-term ownership goals similar to their predecessors. Work-life balance is important to both residents and working orthodontists. The desire to spend more quality time with family friends at the cost of income is contributed to increased job satisfaction later in one’s career.

description: Motivated by model calculations for the heavy fermion superconductor CePt3Si predicting phonon anomalies because of anti-symmetric spin-orbit coupling we performed a detailed experimental study of the lattice dynamical properties of CePt3Si. In particular, we investigated the dispersion of transverse acoustic and low energy optic phonon branches along the [110] direction using inelastic neutron scattering. In these branches, we found deviations from our ab-initio lattice dynamical calculations, which overall give a good description of the phonon dispersion in CePt3Si. However, the agreement for the [110] transverse modes can be improved if we neglect the Ce 4f states, done in an additional calculation. We conclude that the lattice dynamics of CePt3Si are conventional and that the observed deviations are not related to effects of anti-symmetric spin-orbit-coupling. More likely, ab-initio calculations overestimate the exchange between different phonon branches, particularly in the presence of 4f electron states. Our results imply that the ASOC plays less a role in non-centrosymmetric superconductors than commonly believed.

title: Plays, Politics and Pedagogy: Lancastrian Drama c.1400–1461
Creators: name: Claridge, Alexandra
Publisher: name: University of Liverpool Repository
Year: 2525

description: The Lancastrian kings are well known historical figures but comparatively little is known about the culture of drama and performance which surrounded them. Plays, Politics and Pedagogy: Lancastrian Drama c.1400–1461 explores the extensive culture of dramatic activity engaged in by members of the Lancastrian family. Drama in the early fifteenth-century society was often shaped by political concerns but, when Henry VI became king aged nine months, politics and drama was reorientated around a child. A study of Lancastrian drama necessarily includes dramatic activity for and about children. Consequently, this thesis offers a rare case study in contextualising fifteenth-century child-focused drama. Through connecting extant play texts to historical records, this study finds a flourishing culture of pedagogical drama among the Lancastrian family and their networks. The core texts upon which this study is based are diverse. Some are by well-known writers, such as John Lydgate or Titus Livius Frulovisi, while others, like ‘The Winchester Dialogues’, are anonymous. Reading these texts in their historical context and connecting them with members of a single, if powerful, family, allows this thesis to reveal how the concerns of the Lancastrian court, including anxieties about childhood, were expressed through drama.

description: This paper investigates the effects that the extensive use of communication technologies, fostered by the pandemic, has on organizational inclusion. It is an explorative study that offers theoretical reflections supported by analysis of interviews and journalistic reports of disabled people’s experience with communication technologies and assistive devices. We argue that such technology, although able to foster unexpected changes in work activities, is not inclusive in itself, as it can also produce errors, malfunctions, frustrations, misnarration. Therefore, we propose a relational approach that sees inclusion not in terms of the adoption of single accessibility devices, nor of specific policies in HR management, but rather as a dynamic process characterized by multimodal action-nets, composed of multiple socio-material agents and nodes, both human and non-human, and complex interdependencies between individuals, public and private organizations, technological artifacts, design, IT services and data processing, hiring policies, knowledge and narratives. Such an approach highlights the fruitful connection between inclusion and resilience.

description: Style transfer for out-of-domain (OOD) singing voice synthesis (SVS) focuses on generating high-quality singing voices with unseen styles (such as timbre, emotion, pronunciation, and articulation skills) derived from reference singing voice samples. However, the endeavor to model the intricate nuances of singing voice styles is an arduous task, as singing voices possess a remarkable degree of expressiveness. Moreover, existing SVS methods encounter a decline in the quality of synthesized singing voices in OOD scenarios, as they rest upon the assumption that the target vocal attributes are discernible during the training phase. To overcome these challenges, we propose StyleSinger, the first singing voice synthesis model for zero-shot style transfer of out-of-domain reference singing voice samples. StyleSinger incorporates two critical approaches for enhanced effectiveness: 1) the Residual Style Adaptor (RSA) which employs a residual quantization module to capture diverse style characteristics in singing voices, and 2) the Uncertainty Modeling Layer Normalization (UMLN) to perturb the style attributes within the content representation during the training phase and thus improve the model generalization. Our extensive evaluations in zero-shot style transfer undeniably establish that StyleSinger outperforms baseline models in both audio quality and similarity to the reference singing voice samples. Access to singing voice samples can be found at https://aaronz345.github.io/StyleSingerDemo/.

title: The impact of child obesity news on UK household food expenditure
Creators: name: Silva, Andres
Publisher: name: University of Kent
Year: 2022

description: The United Kingdom (UK) has one of the highest obesity levels in the world (Mazzocchi, Traill and Shogren, 2009). As indicated by the National Health Service (2010), 25% of adults and 17% of children are obese in the UK. This last statistic represents an increase of four points in comparison to 1995. The Government Office for Science (2010) estimated that by 2050, half of the UK population would be obese, with a consequent direct annual cost of £ 1 0 billion and an indirect annual cost of £50 billion at today's prices. Governments have the role of ensuring that households have the most complete information possible about their food choices (Mazzocchi, Traill and Shogren, 2009). With this objective, the UK government has conducted information campaigns such as nutritional food labelling and the 'Change 4 Life' campaign, in order to increase nutritional awareness. Despite government efforts, obesity has been steadily increasing in the UK. This research aims to contribute to the debate on how health-related information impacts household food expenditure and whether this impact varies across income groups and household composition. This study specifically measures the impact of child obesity news on household food expenditure in the UK. To this end, the study calculated a set of elasticities for different income groups (high vs. low) and family composition (families with and without children). This set of elasticities gives us a measure of responsiveness, to change in terms of price, income and news. This study uses an augmented two-stage budgeting demand system. Demand systems combine price, income and news index data into a well-supported economic framework. The empirical analysis includes testing for homogeneity, symmetry, concavity and the time series properties of the data and the residuals. In the UK, no recent study has measured the impact of news on household food expenditure. Moreover, few empirical demand studies use structural approaches that are consistent with the time series properties of the data.
Self-induced flavor conversion of supernova neutrinos on small scales

description: Self-induced flavor conversion of supernova (SN) neutrinos is a generic feature of neutrino-neutrino dispersion. The corresponding run-away modes in flavor space can spontaneously break the original symmetries of the neutrino flux and in particular can spontaneously produce small-scale features as shown in recent schematic studies. However, the unavoidable "multi-angle matter effect" shifts these small-scale instabilities into regions of matter and neutrino density which are not encountered on the way out from a SN. The traditional modes which are uniform on the largest scales are most prone for instabilities and thus provide the most sensitive test for the appearance of self-induced flavor conversion. As a by-product we clarify the relation between the time evolution of an expanding neutrino gas and the radial evolution of a stationary SN neutrino flux. Our results depend on several simplifying assumptions, notably stationarity of the solution, the absence of a "backward" neutrino flux caused by residual scattering, and global spherical symmetry of emission.

description: We study the effects of hybridization between the two electron pockets in Fe-based superconductors with s-wave gap with accidental nodes. We argue that hybridization reconstructs the Fermi surfaces and also induces an additional inter-pocket pairing component. We analyze how these two effects modify the gap structure by tracing the position of the nodal points of the energy dispersions in the superconducting state. We find three possible outcomes. In the first, the nodes simply shift their positions in the Brillouin zone; in the second, the nodes merge and disappear, in which case the gap function has either equal or opposite signs on the electron pockets; in the third, a new set of nodal points emerges, doubling the original number of nodes.

Our analysis is model independent and based on symmetry considerations alone. The identities we obtain are valid to all orders in the slow roll expansion. For special conformal transformations, the Ward identities include a term which is non-linear in the fields that arises due to a compensating spatial reparametrization. Some observational consequences are also discussed.

description: Dust acoustic waves in the bulk of a dust cloud in complex plasma of low-pressure gas discharge under microgravity conditions are considered. The complex plasma is assumed to conform to the ionization equation of state (IEOS) developed in our previous study. This equation implies the ionization similarity of plasmas. We find singular points of IEOS that determine the behavior of the sound velocity in different regions of the cloud. The fluid approach is utilized to deduce the wave equation that includes the neutral drag term. It is shown that the sound velocity is fully defined by the particle compressibility, which is calculated on the basis of the used IEOS. The sound velocities and damping rates calculated for different three-dimensional complex plasmas both in ac and dc discharges demonstrate a good correlation with experimental data that are within the limits of validity of the theory. The theory provides interpretation for the observed independence of the sound velocity on the coordinate and for a weak dependence on the particle diameter and gas pressure. Predictive estimates are made for the ongoing PK-4 experiment.

Is collaboration during videoconferencing encounters a meaningful experience? An ‘embodied’ affordance approach to explore challenges and opportunities
Creators: name: Shaba, Emanuela

Year: 2022
Subjects: Organization

description: As videoconferencing encounters have become ‘business as usual’, team members are forced to increasingly actualize technological affordances to be able to interact and collaborate to reach goals. Affordance research on virtual collaboration has neglected one fundamental dimension of the experienced relationship between humans and technology, the materiality of the ‘space between’, through which the situated practices become inherently meaningful. Thereby, this study endeavored to enquire the emerging experience of the human (body)-technology relationship, and its implications for relational aspects of collaboration. Empirical results indicate that due to lack of resonance of bodily movements to the things to which it attends, members are experiencing weakened intrinsic temporal dimensions of conversation in the virtual space, conducive of frustration and lack of trust in the technology. The higher level of distraction and disengagement that follows is suppressing ‘triggered attendance’ and spontaneous initiation of social interaction, two main antecedents of sharing and collaboration. Findings enrich knowledge on the body-emotions-technology relations in the novel context, while disentangling implications for aspects of work.

description: I review the current state of numerical simulations of stellar feedback in the context of star formation at scales ranging from the formation of individual stars to models of galaxy formation including cosmic reionisation. I survey the wealth of algorithms developed recently to solve the radiative transfer problem and to simulate stellar winds, supernovae and protostellar jets. I discuss the results of these simulations with regard to star formation in molecular clouds, the interaction of different feedback mechanisms with each other and with magnetic fields, and in the wider context of galactic-- and cosmological--scale simulations.

Performance Improvement in Risk Assessment for Hepatitis A, B, and C among Asymptomatic Hmong Patients in a Primary Care Setting
Creators: name: Lo, Ka Blia Nicky
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: The Hmong, a minority Asian subgroup, have one of the highest rates of infectious hepatitis in the United States.  In 2014, the United States Preventive Services Task Force (USPSTF) expanded hepatitis B recommendations to include individuals born in hepatitis high prevalent regions and American born individuals not vaccinated as infants whose parents were born in very high prevalent regions. These regions include the Southeast Asian countries, areas where the Hmong people emigrated from.       The project purpose was to increase hepatitis A (HAV), hepatitis B (HBV), and hepatitis C (HCV) risk assessments in adult patients, using the USPSTF’s 2014 HBV and 2013 HCV recommendations and the Centers for Disease Control and Prevention’s (CDC’s) HAV and HBV immunization recommendations.  The project used evidence-based interventions and the Diffusion of Innovation and Culture Care Theories.  Measures used in evaluating the intervention included provider and staff pre-test post-test surveys, a modified hepatitis risk assessment tool (HRAT), and qualitative feedback from clinic staff and community members.  The HRAT utilization was implemented among the patients of one provider.  Results were analyzed using frequencies, descriptive statistics, and paired t-tests to determine if perspectives on hepatitis risk screening changed from pre- to post- survey.        Attitudes and skills of staff and providers did not improve in six out of eight survey questions; however, the majority of the respondents reported positive views in risk screening in both the pre- and post-intervention surveys.  Knowledge scores improved 26.37 percentage points, with staff having the most improvement (+38.29%).  The provider screened 196 patients, with a 43% HRAT utilization rate.  This study found that 95.2% Hmong (n = 20 of 21) and 92.3% Asian (n = 12 of 13) patients had the highest risk for HBV, with the 95.2% Hmong (n = 20 of 21) and 100% Asian (n = 13) patients meeting the USPSTF’s recommendations.       This project piloted interventions to increase hepatitis risk screening, increase patient hepatitis education, and improve provider recommendations to further improve patient outcomes for those who have viral hepatitis risks.  Further work is needed to identify ways to create a system change for clinic staff to increase risk screening rates.

description: We study the character of the first excited 1/2^{+} state of {9}^Be, which is observed as a low-lying sharp peak in the cross section of 9^Be(γ,n)2α just above the {8}^Be+n threshold. Using the α+α+n three-body model, we describe the ground and excited unbound states of {9}^Be above the α+α+n threshold. Applying the complex scaling method to the three-body model, we find no 1/2^{+} resonant solutions, while the low-lying peak in the photodisintegration cross section is reproduced in the present calculation. It is found that the low-lying peak is dominantly explained by the 8^Be+n component. Furthermore, using the analytical continuation of the coupling constant of the three-body interaction for the α+α+n system, we discuss the virtual-state character of the 1/2^{+} state.

description: Considered as an exogenous and continuous shock characterized by great difficulty in descriptive terms, COVID-19 management required out of the ordinary organizational approaches for hospitals. This paper aims to highlight the resilience factors than can curb or accelerate the rebooting phase of the resilient process for hospitals under COVID-19 stress. Resilience is here considered as a multilevel, multidimensional, and dynamic construct mainly composed of three characteristics: robustness, redundancy, resourcefulness. Technology resulted as an activator of change working as a booster in the rebooting phase. By leveraging on the concept of learning ambidexterity, hospitals made choices between exploitation and exploration-oriented activities. In this direction, it was found that it is necessary to acquire and develop crisis management skills as the existing pre-pandemic ones proved unable to cover a wide range of not linear issues such as those brought about by COVID-19.

description: Dynamic mode decomposition (DMD) provides a practical means of extracting insightful dynamical information from fluids datasets. Like any data processing technique, DMD's usefulness is limited by its ability to extract real and accurate dynamical features from noise-corrupted data. Here we show analytically that DMD is biased to sensor noise, and quantify how this bias depends on the size and noise level of the data. We present three modifications to DMD that can be used to remove this bias: (i) a direct correction of the identified bias using known noise properties, (ii) combining the results of performing DMD forwards and backwards in time, and (iii) a total least-squares-inspired algorithm. We discuss the relative merits of each algorithm, and demonstrate the performance of these modifications on a range of synthetic, numerical, and experimental datasets. We further compare our modified DMD algorithms with other variants proposed in recent literature.
